Typescript from v1.4 has the type keyword which declares a type alias (analogous to a typedef in C/C++). You can declare your callback type thus:

type CallbackFunction = () => void;

which declares a function that takes no arguments and returns nothing. A function that takes zero or more arguments of any type and returns nothing would be:

type CallbackFunctionVariadic = (...args: any[]) => void;

Then you can say, for example,

let callback: CallbackFunctionVariadic = function(...args: any[]) {
  // do some stuff
};

If you want a function that takes an arbitrary number of arguments and returns anything (including void):

type CallbackFunctionVariadicAnyReturn = (...args: any[]) => any;

You can specify some mandatory arguments and then a set of additional arguments (say a string, a number and then a set of extra args) thus:

type CallbackFunctionSomeVariadic =
  (arg1: string, arg2: number, ...args: any[]) => void;

This can be useful for things like EventEmitter handlers.

Functions can be typed as strongly as you like in this fashion, although you can get carried away and run into combinatoric problems if you try to nail everything down with a type alias.

You need to set the error mode attribute PDO::ATTR_ERRMODE to PDO::ERRMODE_EXCEPTION.
And since you expect the exception to be thrown by the prepare() method you should disable the PDO::ATTR_EMULATE_PREPARES* feature. Otherwise the MySQL server doesn't "see" the statement until it's executed.

<?php
try {
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);


    $pdo->prepare('INSERT INTO DoesNotExist (x) VALUES (?)');
}
catch(Exception $e) {
    echo 'Exception -> ';
    var_dump($e->getMessage());
}

prints (in my case)

Exception -> string(91) "SQLSTATE[42S02]: Base table or view not found: 
1146 Table 'test.doesnotexist' doesn't exist"

see http://wezfurlong.org/blog/2006/apr/using-pdo-mysql/
EMULATE_PREPARES=true seems to be the default setting for the pdo_mysql driver right now. The query cache thing has been fixed/change since then and with the mysqlnd driver I hadn't problems with EMULATE_PREPARES=false (though I'm only a php hobbyist, don't take my word on it...)

*) and then there's PDO::MYSQL_ATTR_DIRECT_QUERY - I must admit that I don't understand the interaction of those two attributes (yet?), so I set them both, like

$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly', array(
    PDO::ATTR_EMULATE_PREPARES=>false,
    PDO::MYSQL_ATTR_DIRECT_QUERY=>false,
    PDO::ATTR_ERRMODE=>PDO::ERRMODE_EXCEPTION
));

Have you tried:

#!/usr/local/bin/php

I.e. without the -q part? That's what the error message "Could not open input file: -q" means. The first argument to php if it doesn't look like an option is the name of the PHP file to execute, and -q is CGI only.

EDIT: A couple of (non-related) tips:

1. You don't need to terminate the last block of PHP with ?>. In fact, it is often better not to.
2. When executed on the command line, PHP defines the global constant STDIN to fopen("php://stdin", "r"). You can use that instead of opening "php://stdin" a second time: $fd = STDIN;

The read_sql docs say this params argument can be a list, tuple or dict (see docs).

To pass the values in the sql query, there are different syntaxes possible: ?, :1, :name, %s, %(name)s (see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2 in your case I suppose).

In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2 documentation, they support the %(name)s style (and so not the :name I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:

df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
                     'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
                   db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
                   index_col=['Timestamp'])

If you are using Scene Builder, you will see at the right an accordion panel which normally has got three options ("Properties", "Layout" and "Code"). In the second one ("Layout"), you will see an option called "[parent layout] Constraints" (in your case "AnchorPane Constrainsts").

You should put "0" in the four sides of the element wich represents the parent layout.

If you are using boost libs you can obtain a random generator in this way:

#include <iostream>
#include <string>

// Used in randomization
#include <ctime>
#include <boost/random/mersenne_twister.hpp>
#include <boost/random/uniform_int_distribution.hpp>
#include <boost/random/variate_generator.hpp>

using namespace std;
using namespace boost;

int current_time_nanoseconds(){
    struct timespec tm;
    clock_gettime(CLOCK_REALTIME, &tm);
    return tm.tv_nsec;
}

int main (int argc, char* argv[]) {
    unsigned int dice_rolls = 12;
    random::mt19937 rng(current_time_nanoseconds());
    random::uniform_int_distribution<> six(1,6);

    for(unsigned int i=0; i<dice_rolls; i++){
        cout << six(rng) << endl;
    }
}

Where the function current_time_nanoseconds() gives the current time in nanoseconds which is used as a seed.

Here is a more general class to get random integers and dates in a range:

#include <iostream>
#include <ctime>
#include <boost/random/mersenne_twister.hpp>
#include <boost/random/uniform_int_distribution.hpp>
#include <boost/random/variate_generator.hpp>
#include "boost/date_time/posix_time/posix_time.hpp"
#include "boost/date_time/gregorian/gregorian.hpp"


using namespace std;
using namespace boost;
using namespace boost::posix_time;
using namespace boost::gregorian;


class Randomizer {
private:
    static const bool debug_mode = false;
    random::mt19937 rng_;

    // The private constructor so that the user can not directly instantiate
    Randomizer() {
        if(debug_mode==true){
            this->rng_ = random::mt19937();
        }else{
            this->rng_ = random::mt19937(current_time_nanoseconds());
        }
    };

    int current_time_nanoseconds(){
        struct timespec tm;
        clock_gettime(CLOCK_REALTIME, &tm);
        return tm.tv_nsec;
    }

    // C++ 03
    // ========
    // Dont forget to declare these two. You want to make sure they
    // are unacceptable otherwise you may accidentally get copies of
    // your singleton appearing.
    Randomizer(Randomizer const&);     // Don't Implement
    void operator=(Randomizer const&); // Don't implement

public:
    static Randomizer& get_instance(){
        // The only instance of the class is created at the first call get_instance ()
        // and will be destroyed only when the program exits
        static Randomizer instance;
        return instance;
    }
    bool method() { return true; };

    int rand(unsigned int floor, unsigned int ceil){
        random::uniform_int_distribution<> rand_ = random::uniform_int_distribution<> (floor,ceil);
        return (rand_(rng_));
    }

    // Is not considering the millisecons
    time_duration rand_time_duration(){
        boost::posix_time::time_duration floor(0, 0, 0, 0);
        boost::posix_time::time_duration ceil(23, 59, 59, 0);
        unsigned int rand_seconds = rand(floor.total_seconds(), ceil.total_seconds());

        return rand_date_in_interval(epoch, ceil_date);
    }

    date rand_date_in_interval(date floor_date, date ceil_date){

        long long step_seconds = Randomizer::get_instance().rand(0, gap_seconds);

    }
};

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

You can do the following if you already know the number of fields of the input:

client_name = raw_input("Enter you first and last name: ")
first_name, last_name = client_name.split() 

and in case you want to iterate through the fields separated by spaces, you can do the following:

some_input = raw_input() # This input is the value separated by spaces
for field in some_input.split():
    print field # this print can be replaced with any operation you'd like
    #             to perform on the fields.

A more generic use of the "split()" function would be:

    result_list = some_string.split(DELIMITER)

where DELIMETER is replaced with the delimiter you'd like to use as your separator, with single quotes surrounding it.

An example would be:

    result_string = some_string.split('!')    

The code above takes a string and separates the fields using the '!' character as a delimiter.

pip is also a python package. So the easiest way to install modules to a specific python version would be below

 python2.7 /usr/bin/pip install foo

or

python2.7 -m pip install foo

v$resource_limit view is so interesting for me in order to glance oracle sessions,processes..:

https://bbdd-error.blogspot.com.es/2017/09/check-sessions-and-processes-limit-in.html

Similar problem - same error message. I got the same message when trying to clone something from bitbucket with ssh. The problem was in my ssh configuration configured in the mercurial.ini: I used the wrong bitbucket username. After I corrected the user name things worked.

Just changed Amber's COUNT(*) to COUNT(1) for the better performance.

SELECT name, COUNT(1) as count 
FROM tablename 
GROUP BY name 
ORDER BY count DESC;

It took me a while to develop something that took the accepted answer and turned it into a robust function.

I am not sure about others, but I work in an environment with machines on both PowerShell version 2 and 3, so I needed to handle both. The following function offers a graceful fallback:

Function Get-PSScriptRoot
{
    $ScriptRoot = ""

    Try
    {
        $ScriptRoot = Get-Variable -Name PSScriptRoot -ValueOnly -ErrorAction Stop
    }
    Catch
    {
        $ScriptRoot = Split-Path $script:MyInvocation.MyCommand.Path
    }

    Write-Output $ScriptRoot
}

It also means that the function refers to the Script scope rather than the parent's scope as outlined by Michael Sorens in one of his blog posts.

Read the manual, it covers it very well: http://php.net/manual/en/function.mysql-query.php

Usually you do something like this:

while ($row = mysql_fetch_assoc($result)) {
  echo $row['firstname'];
  echo $row['lastname'];
  echo $row['address'];
  echo $row['age'];
}

Might help some else - I came here because I missed putting two // after http:. This is what I had:

http:/abc.my.domain.com:55555/update

Another way (although it is a longer code) but it is faster than the above codes. Check it using %timeit function:

df[df.index.isin([1,3])]

PS: You figure out the reason

A Window object is just what it sounds like: its a new Window for your application. You should use it when you want to pop up an entirely new window. I don't often use more than one Window in WPF because I prefer to put dynamic content in my main Window that changes based on user action.

A Page is a page inside your Window. It is mostly used for web-based systems like an XBAP, where you have a single browser window and different pages can be hosted in that window. It can also be used in Navigation Applications like sellmeadog said.

A UserControl is a reusable user-created control that you can add to your UI the same way you would add any other control. Usually I create a UserControl when I want to build in some custom functionality (for example, a CalendarControl), or when I have a large amount of related XAML code, such as a View when using the MVVM design pattern.

When navigating between windows, you could simply create a new Window object and show it

var NewWindow = new MyWindow();
newWindow.Show();

but like I said at the beginning of this answer, I prefer not to manage multiple windows if possible.

My preferred method of navigation is to create some dynamic content area using a ContentControl, and populate that with a UserControl containing whatever the current view is.

<Window x:Class="MyNamespace.MainWindow" ...>
    <DockPanel>
        <ContentControl x:Name="ContentArea" />
    </DockPanel>
</Window>

and in your navigate event you can simply set it using

ContentArea.Content = new MyUserControl();

But if you're working with WPF, I'd highly recommend the MVVM design pattern. I have a very basic example on my blog that illustrates how you'd navigate using MVVM, using this pattern:

<Window x:Class="SimpleMVVMExample.ApplicationView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:SimpleMVVMExample"
        Title="Simple MVVM Example" Height="350" Width="525">

   <Window.Resources>
      <DataTemplate DataType="{x:Type local:HomeViewModel}">
         <local:HomeView /> <!-- This is a UserControl -->
      </DataTemplate>
      <DataTemplate DataType="{x:Type local:ProductsViewModel}">
         <local:ProductsView /> <!-- This is a UserControl -->
      </DataTemplate>
   </Window.Resources>

   <DockPanel>
      <!-- Navigation Buttons -->
      <Border DockPanel.Dock="Left" BorderBrush="Black"
                                    BorderThickness="0,0,1,0">
         <ItemsControl ItemsSource="{Binding PageViewModels}">
            <ItemsControl.ItemTemplate>
               <DataTemplate>
                  <Button Content="{Binding Name}"
                          Command="{Binding DataContext.ChangePageCommand,
                             RelativeSource={RelativeSource AncestorType={x:Type Window}}}"
                          CommandParameter="{Binding }"
                          Margin="2,5"/>
               </DataTemplate>
            </ItemsControl.ItemTemplate>
         </ItemsControl>
      </Border>

      <!-- Content Area -->
      <ContentControl Content="{Binding CurrentPageViewModel}" />
   </DockPanel>
</Window>

This is not an exact duplicate of sprintf; however, it is similar and more powerful: https://github.com/anywhichway/stringformatter

Format expressions using this library take the form of embedded Javascript objects, e.g.

format("I have {number: {currency: "$", precision:2}}.",50.2); 

will return "I have $50.20.".

Instead of sudo, try

su - username command

In my experience, sudo is not always available on RHEL systems, but su is, because su is part of the coreutils package whereas sudo is in the sudo package.

Void is used only in method signatures. For return types it means method will not return anything to the calling code. For parameters it means, no parameters are passed to the method

e.g.

void MethodThatReturnsAndTakesVoid(void)
{
// Method body
}

In C# we can omit the void for parameters and can write the above code as:

void MethodThatReturnsAndTakesVoid()
{
// Method body
}

Void should not be confused with null. Null means for the variable whose address is on stack, the value on the heap for that address is empty.

Based on the above stuff:

import matplotlib.pyplot as plt
import matplotlib.font_manager as fm

fontPath = "/usr/share/fonts/abc.ttf"
font = fm.FontProperties(fname=fontPath, size=10)
font2 = fm.FontProperties(fname=fontPath, size=24)

fig = plt.figure(figsize=(32, 24))
fig.text(0.5, 0.93, "This is my Title", horizontalalignment='center', fontproperties=font2)

plot = fig.add_subplot(1, 1, 1)

plot.xaxis.get_label().set_fontproperties(font)
plot.yaxis.get_label().set_fontproperties(font)
plot.legend(loc='upper right', prop=font)

for label in (plot.get_xticklabels() + plot.get_yticklabels()):
    label.set_fontproperties(font)

Use a vertical bar (|) for "or".

case "$C" in
"1")
    do_this()
    ;;
"2" | "3")
    do_what_you_are_supposed_to_do()
    ;;
*)
    do_nothing()
    ;;
esac

All I did is:

map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds));

And it works on V3 API.

You can use pyperclip - cross-platform clipboard module. Or Xerox - similar module, except requires the win32 Python module to work on Windows.

private boolean current;

public void setCurrent(boolean current){
    this.current=current;
}

public boolean hasCurrent(){
    return this.current;
}

For what its worth, COALESCE is similiar but

IFNULL(expr1, default)

is the exact match you're looking for in DB2.

COALESCE allows multiple arguments, returning the first NON NULL expression, whereas IFNULL only permits the expression and the default.

Thus

SELECT product.ID, IFNULL(product.Name, "Internal") AS ProductName
FROM Product

Gives you what you're looking for as well as the previous answers, just adding for completeness.

This problems gave me great headache when i tried to use reverse for generating activation link and send it via email of course. So i think from tests.py it will be same. The correct way to do this is following:

from django.test import Client
from django.core.urlresolvers import reverse

#app name - name of the app where the url is defined
client= Client()
response = client.get(reverse('app_name:edit_project', project_id=4)) 

you can use rindex() function to get the last occurrence of a character in string

s="hellloooloo"
b='l'
print(s.rindex(b))

for (int i = 0; i < list.size(); i++) {
  for (int j = i+1; j < list.size(); j++) {
    // compare list.get(i) and list.get(j)
  }
}

If you don't want to commit, or want to commit later (commit message will still be prepared for you, which you can also edit):

git revert -n <commit>

There is charts4j which is a charts and graphs API. It enables developers to programmatically create the charts available in the Google Chart API through a straightforward and intuitive Java API.

Disclaimer: I wrote charts4j. We will be doing another major release in the next few weeks.

You could just check if the value is not zero.

if ((Int32)(letter & Letters.AB) != 0) { }

But I would consider it a better solution to introduce a new enumeration value with value zero and compare agains this enumeration value (if possible because you must be able to modify the enumeration).

[Flags]
enum Letters
{
    None = 0,
    A    = 1,
    B    = 2,
    C    = 4,
    AB   =  A | B,
    All  = AB | C
}

if (letter != Letters.None) { }

UPDATE

Missread the question - fixed the first suggestion and just ignore the second suggestion.

This site has two pretty simple solutions - just check the code, I provided the descriptions in case you wanted them - saves you some clicks.

http://www.richardlord.net/blog/dates-in-php-and-mysql

1.One common solution is to store the dates in DATETIME fields and use PHPs date() and strtotime() functions to convert between PHP timestamps and MySQL DATETIMEs. The methods would be used as follows -

$mysqldate = date( 'Y-m-d H:i:s', $phpdate );
$phpdate = strtotime( $mysqldate );

2.Our second option is to let MySQL do the work. MySQL has functions we can use to convert the data at the point where we access the database. UNIX_TIMESTAMP will convert from DATETIME to PHP timestamp and FROM_UNIXTIME will convert from PHP timestamp to DATETIME. The methods are used within the SQL query. So we insert and update dates using queries like this -

$query = "UPDATE table SET
    datetimefield = FROM_UNIXTIME($phpdate)
    WHERE...";
$query = "SELECT UNIX_TIMESTAMP(datetimefield)
    FROM table WHERE...";

Navigate via shell inside of your project folder and run following command:

mvn -U clean install

Usually this should already solve your problem.

If you see a message like this:

Could not resolve dependencies for project :war:0.0.1-SNAPSHOT: Failed to collect dependencies at com.sun.jersey:jersey-server:jar:1.9

Then execute:

export MAVEN_OPTS=-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

followed by:

mvn -U clean install

again to finally update your dependencies.

Afterwards perform clean maven build:

maven clean install

You can use this function (I found it here: http://excelribbon.tips.net/T010780_Colors_in_an_IF_Function.html):

Function GetFillColor(Rng As Range) As Long
    GetFillColor = Rng.Interior.ColorIndex
End Function

Here is an explanation, how to create user-defined functions: http://www.wikihow.com/Create-a-User-Defined-Function-in-Microsoft-Excel

In your worksheet, you can use the following: =GetFillColor(B5)

I think the problem is you have to use the ! to unbundle identifier

I have

override func prepareForSegue(segue: UIStoryboardSegue?, sender: AnyObject?) {
        if segue!.identifier == "Details" {
            let viewController:ViewController = segue!.destinationViewController as ViewController
            let indexPath = self.tableView.indexPathForSelectedRow()
            viewController.pinCode = self.exams[indexPath.row]

        }

    }

My understanding is that without the ! you just get a true or false value

Check out this link.. It helped me a lot.

http://www.w3schools.com/jsref/jsref_toprecision.asp

The toPrecision(no_of_digits_required) function returns a string so don't forget to use the parseFloat() function to convert to decimal point of required precision.

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

In the latest mongoose (3.8.1 at the time of writing), you do two things differently: (1) you have to pass single argument to sort(), which must be an array of constraints or just one constraint, and (2) execFind() is gone, and replaced with exec() instead. Therefore, with the mongoose 3.8.1 you'd do this:

var q = models.Post.find({published: true}).sort({'date': -1}).limit(20);
q.exec(function(err, posts) {
     // `posts` will be of length 20
});

or you can chain it together simply like that:

models.Post
  .find({published: true})
  .sort({'date': -1})
  .limit(20)
  .exec(function(err, posts) {
       // `posts` will be of length 20
  });

To delete the last element of the lists, you could use:

def deleteLast(self):
    if self.Ans:
        del self.Ans[-1]
    if self.masses:
        del self.masses[-1]

You don't need jQuery for this. Here's a simple working example:

                top: 49%;
                left: 48.85%;
            }
        </style>
        <script type="text/javascript">
            window.onload = function(){

                var x, y;
    // On mousemove use event.clientX and event.clientY to set the location of the div to the location of the cursor:

I chose position: fixed; so scrolling wouldn't be an issue.

Try using the following pattern in scanf. It will read until the end of the line:

scanf("%d\n", &n)

You won't need the getchar() inside the loop since scanf will read the whole line. The floats won't match the scanf pattern and the prompt will ask for an integer again.

Jonathon gave you an approach using dict comprehensions in his answer. Here is an approach that deals with your do something part.

If you want to do something with the values of the dictionary, you don't need a dictionary comprehension at all:

I'm using iteritems() since you tagged your question with python-2.7

results = map(some_function, [(k,v) for k,v in a_dict.iteritems() if 'foo' in k])

Now the result will be in a list with some_function applied to each key/value pair of the dictionary, that has foo in its key.

If you just want to deal with the values and ignore the keys, just change the list comprehension:

results = map(some_function, [v for k,v in a_dict.iteritems() if 'foo' in k])

some_function can be any callable, so a lambda would work as well:

results = map(lambda x: x*2, [v for k,v in a_dict.iteritems() if 'foo' in k])

The inner list is actually not required, as you can pass a generator expression to map as well:

>>> map(lambda a: a[0]*a[1], ((k,v) for k,v in {2:2, 3:2}.iteritems() if k == 2))
[4]

After facing a similar issue, below is what I did :

• Created a class extending javax.ws.rs.core.Application and added a Cors Filter to it.

To the CORS filter, I added corsFilter.getAllowedOrigins().add("http://localhost:4200");.

Basically, you should add the URL which you want to allow Cross-Origin Resource Sharing. Ans you can also use "*" instead of any specific URL to allow any URL.

public class RestApplication
    extends Application
{
    private Set<Object> singletons = new HashSet<Object>();

    public MessageApplication()
    {
        singletons.add(new CalculatorService()); //CalculatorService is your specific service you want to add/use.
        CorsFilter corsFilter = new CorsFilter();
        // To allow all origins for CORS add following, otherwise add only specific urls.
        // corsFilter.getAllowedOrigins().add("*");
        System.out.println("To only allow restrcited urls ");
        corsFilter.getAllowedOrigins().add("http://localhost:4200");
        singletons = new LinkedHashSet<Object>();
        singletons.add(corsFilter);
    }

    @Override
    public Set<Object> getSingletons()
    {
        return singletons;
    }
}

• And here is my web.xml:

<web-app id="WebApp_ID" version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <url-pattern>/rest/*</url-pattern>

The most important code which I was missing when I was getting this issue was, I was not adding my class extending javax.ws.rs.Application i.e RestApplication to the init-param of <servlet-name>resteasy-servlet</servlet-name>

   <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.app.RestApplication</param-value>
    </init-param>

And therefore my Filter was not able to execute and thus the application was not allowing CORS from the URL specified.

here is the thing i did for the same trouble i had.

when I'm passing the text to the next page in jsp, i'm reading it as a textarea instead of reading something like

so the output came as you wanted. and for other properties, you can use as below.

<textarea style="background-color: white; border: none; width:660px;font-family: Arial, Helvetica, sans-serif; font-size:1.0em; resize:none;" name="text" cols="75" rows="15" readonly="readonly" ><s:property value="%{text}"/></textarea>

Use img.Convert(), supports “L”, “RGB” and “CMYK.” mode

import numpy as np
from PIL import Image

img = Image.open("IMG/center_2018_02_03_00_34_32_784.jpg")
img.convert('L')

print np.array(img)

Output:

 [137 130 137 ...,   9  20  13]
 [170 177 183 ...,  14  10 250]

OK, answering to my own question.

Steps to connect LocalDB to Visual Studio Server Explorer

1. Open command prompt
2. Run SqlLocalDB.exe start v11.0
3. Run SqlLocalDB.exe info v11.0
4. Copy the Instance pipe name that starts with np:\...
5. In Visual Studio select TOOLS > Connect to Database...
6. For Server Name enter (localdb)\v11.0. If it didn't work, use the Instance pipe name that you copied earlier. You can also use this to connect with SQL Management Studio.
7. Select the database on next dropdown list
8. Click OK

You've accidentally set "Pause on Exceptions" to all/uncaught exceptions.

Go to the "Sources" tab. At the bottom toolbar, toggle the button that looks like the pause symbol surrounded by a circle (4th button from the left) until the color of the circle turns black to turn it off.

It can be useful to someone that uses a different system that does not have that library readily available. If that is not declared and you have some functions in your script that are not supported by that system, you should declare #/bin/bash. I've ran into this problem before at work and now I just include it as a practice.

StandardScaler performs the task of Standardization. Usually a dataset contains variables that are different in scale. For e.g. an Employee dataset will contain AGE column with values on scale 20-70 and SALARY column with values on scale 10000-80000.
As these two columns are different in scale, they are Standardized to have common scale while building machine learning model.

Be aware that changing locale is process-wide and not thread safe (iow., can have side effects or can affect other code executed within the same process).

My proposition: check out the Babel package. Some means of integrating with Django templates are available.

Using a CLI, the easiest way (cross-platform) I've found is to use the NPM package https://github.com/sindresorhus/open-cli

npm install --global open-cli

Installing it globally allows running something like open-cli https://unlyed.github.io/next-right-now/.

You can also install it locally (e.g: in a project) and run npx open-cli https://unlyed.github.io/next-right-now/

Or, using a NPM script (which is how I actually use it): "doc:online": "open-cli https://unlyed.github.io/next-right-now/",

Running yarn doc:online will open the webpage, and this works on any platform (windows, mac, linux).

The way to get the results of your formula would be to start in a new sheet.

In cell A1 put the formula

=IF('testsheet'!C1 <= 99,'testsheet'!A1,"") 

Copy that cell down to row 40 In cell B1 put the formula

=A1

In cell B2 put the formula

=B1 & A2

Copy that cell down to row 40.

The value you want is now in that column in row 40.

Not really the answer you want, but that is the fastest way to get things done excel wise without creating a custom formula that takes in a range and makes the calculation (which would be more fun to do).

Tried every stuff but this one worked .. 1. Eclipse -> Help -> Install New Software. 2. Type " http://download.eclipse.org/releases/indigo/ " & Hit Enter. 3. Expand " Collaboration " tag. 4. Select Maven plugin from there. 5. Click on next . 6. Accept the agreement & click finish. After installing the maven it will ask for restarting the Eclipse, So restart the eclipse again to see the changes.

Thanks Mukesh for Guiding.

You couldn't login because you did't get proper solt text at login time. There are two options, first is define static salt, second is if you want create dynamic salt than you have to store the salt somewhere (means in database) with associate with user. Than you concatenate user solt+password_hash string now with this you fire query with username in your database table.

That will only work for small numbers and I'm guessing it's also implementation-dependent. Python uses the same object instance for small numbers (iirc <256), but this changes for bigger numbers.

>>> a = 2104214124
>>> b = 2104214124
>>> a == b
True
>>> a is b
False

So you should always use == to compare numbers.

If you can use Java NIO (JDK 1.4 or greater), then I think you're looking for java.nio.channels.FileChannel.lock()

FileChannel.lock()

If you are working with google maps, then check if the lat lng are being passed into new google.maps.LatLng are of a proper format. In my case they were being passed as undefined.

var cumulativeOffset = function(element) {
    var top = 0, left = 0;
    do {
        top += element.offsetTop  || 0;
        left += element.offsetLeft || 0;
        element = element.offsetParent;
    } while(element);

    return {
        top: top,
        left: left
    };
};

You can use "ComboBoxItem.PreviewMouseDown" event. So each time when mouse is down on some item this event will be fired.

To add this event in XAML use "ComboBox.ItemContainerStyle" like in next example:

   <ComboBox x:Name="MyBox"
        ItemsSource="{Binding MyList}"
        SelectedValue="{Binding MyItem, Mode=OneWayToSource}" >
        <ComboBox.ItemContainerStyle>
            <Style>
                <EventSetter Event="ComboBoxItem.PreviewMouseDown"
                    Handler="cmbItem_PreviewMouseDown"/>
            </Style>
        </ComboBox.ItemContainerStyle>
   </ComboBox>

and handle it as usual

void cmbItem_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    //...do your item selection code here...
}

For me, it was due to the project missing Gradle Libraries in its project structure.

Just add in build.gradle: apply plugin: 'idea'

And then run: $ gradle idea

After that gradle rebuilds dependencies libraries and the references are recognized!

You can also use the following syntax for the strongly typed version:

<% using (Html.BeginForm<SomeController>(x=> x.SomeAction(), 
          FormMethod.Post, 
          new { enctype = "multipart/form-data" })) 
   { %>

There's a simple way to this in any C-like language. The style is not Pythonic but works with pure Python:

def remove_html_markup(s):
    tag = False
    quote = False
    out = ""

    for c in s:
            if c == '<' and not quote:
                tag = True
            elif c == '>' and not quote:
                tag = False
            elif (c == '"' or c == "'") and tag:
                quote = not quote
            elif not tag:
                out = out + c

    return out

The idea based in a simple finite-state machine and is detailed explained here: http://youtu.be/2tu9LTDujbw

You can see it working here: http://youtu.be/HPkNPcYed9M?t=35s

For Power-Shell

./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'

For linux(burrowing asnwer from @0x8BADF00D)

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

For single string find in power shell

./adb shell getprop | Select-String -Pattern 'model'

or

./adb shell getprop | Select-String -Pattern '(model)'

For multiple

./adb shell getprop | Select-String -Pattern '(a|b|c|d)'

What about this?

function replaceLast(x, y, z){
  var a = x.split("");
  a[x.lastIndexOf(y)] = z;
  return a.join("");
}

replaceLast("Hello world!", "l", "x"); // Hello worxd!

You can also use:

@Scripts.RenderFormat("<script type=\"text/javascript\" src=\"{0}\"></script>", "~/bundles/mybundle")

To specify the format of your output in a scenario where you need to use Charset, Type, etc.

I had this issue in VS 2015. The following solved it for me:

Find "webpages:Version" in the appsettings and update it to version 3.0.0.0. My web.config had

<add key="webpages:Version" value="2.0.0.0" />

and I updated it to

<add key="webpages:Version" value="3.0.0.0" />

No - but technically there is a work-around (not that i'd actually use it unless forced to):

for(struct { int a; char b; } s = { 0, 'a' } ; s.a < 5 ; ++s.a) 
{
    std::cout << s.a << " " << s.b << std::endl;
}

It doesn't matter - they are exactly the same thing. However, the main thing is that you must be consistent

p.s. I struggle with this sort of "whats the right thing" all the time.

I use following code, found somewhere in the internet don't remember the source though.

    var allText;
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function () {
        if (rawFile.readyState === 4) {
            if (rawFile.status === 200 || rawFile.status == 0) {
                allText = rawFile.responseText;
            }
        }
    }
    rawFile.send(null);
    return JSON.parse(allText);

How about using os.kill? See the docs here: http://docs.python.org/library/os.html#os.kill

Wow, most of the syntax is horrible! Here is one solution with some simpler syntax if you need to indirectly reference arrays:

#!/bin/bash

foo_1=(fff ddd) ;
foo_2=(ggg ccc) ;

for i in 1 2 ;
do
    eval mine=( \${foo_$i[@]} ) ;
    echo ${mine[@]}" " ;
done ;

For simpler use cases I recommend the syntax described in the Advanced Bash-Scripting Guide.

Without a GROUP BY clause, any summation will roll all rows up into a single row, so your query will indeed not work. If you grouped by, say, name, and ordered by sum(c_counts+f_counts), then you might get some useful results. But you would have to group by something.

In Swift 2.0:

UIApplication.sharedApplication().openURL(NSURL(string: "http://stackoverflow.com")!)

This should do it, let me know if you have trouble with it:

Sub foo()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy

'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial

'Close x:
x.Close

End Sub

Alternatively, you could just:

Sub foo2()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1") 

'Close x:
x.Close

End Sub

To extend this to the entire sheet:

With x.Sheets("name of copying sheet").UsedRange
    'Now, paste to y worksheet:
    y.Sheets("sheet name").Range("A1").Resize( _
        .Rows.Count, .Columns.Count) = .Value
End With

And yet another way, store the value as a variable and write the variable to the destination:

Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value

'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals 

'Close x:
x.Close

End Sub

The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:

Copy/PasteSpecial vs Range.Value = Range.Value

That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.

Or in php >= 7.3.0

you can use the function array_key_last()

As described in php.net — Gets the last key of an array

https://www.php.net/manual/en/function.array-key-last.php

Echo the meta tag like this:

URL is the one where the page should be redirected to after the refresh.

echo "<meta http-equiv=\"refresh\" content=\"0;URL=upload.php\">";

I really like the description and the example from http://python-3-patterns-idioms-test.readthedocs.io/en/latest/Visitor.html.

The assumption is that you have a primary class hierarchy that is fixed; perhaps it’s from another vendor and you can’t make changes to that hierarchy. However, your intent is that you’d like to add new polymorphic methods to that hierarchy, which means that normally you’d have to add something to the base class interface. So the dilemma is that you need to add methods to the base class, but you can’t touch the base class. How do you get around this?

The design pattern that solves this kind of problem is called a “visitor” (the final one in the Design Patterns book), and it builds on the double dispatching scheme shown in the last section.

The visitor pattern allows you to extend the interface of the primary type by creating a separate class hierarchy of type Visitor to virtualize the operations performed upon the primary type. The objects of the primary type simply “accept” the visitor, then call the visitor’s dynamically-bound member function.

This is an easy way to blur Images Efficiently with Android's RenderScript that I found on this article

1. Create a Class called BlurBuilder

   public class BlurBuilder {
     private static final float BITMAP_SCALE = 0.4f;
     private static final float BLUR_RADIUS = 7.5f;
   
     public static Bitmap blur(Context context, Bitmap image) {
       int width = Math.round(image.getWidth() * BITMAP_SCALE);
       int height = Math.round(image.getHeight() * BITMAP_SCALE);
   
       Bitmap inputBitmap = Bitmap.createScaledBitmap(image, width, height, false);
       Bitmap outputBitmap = Bitmap.createBitmap(inputBitmap);
   
       RenderScript rs = RenderScript.create(context);
       ScriptIntrinsicBlur theIntrinsic = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));
       Allocation tmpIn = Allocation.createFromBitmap(rs, inputBitmap);
       Allocation tmpOut = Allocation.createFromBitmap(rs, outputBitmap);
       theIntrinsic.setRadius(BLUR_RADIUS);
       theIntrinsic.setInput(tmpIn);
       theIntrinsic.forEach(tmpOut);
       tmpOut.copyTo(outputBitmap);
   
       return outputBitmap;
     }
   }
   

2. Copy any image to your drawable folder

3. Use BlurBuilder in your activity like this:

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       requestWindowFeature(Window.FEATURE_NO_TITLE);
       getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
               WindowManager.LayoutParams.FLAG_FULLSCREEN);
       setContentView(R.layout.activity_login);
   
       mContainerView = (LinearLayout) findViewById(R.id.container);
       Bitmap originalBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.background);
       Bitmap blurredBitmap = BlurBuilder.blur( this, originalBitmap );
       mContainerView.setBackground(new BitmapDrawable(getResources(), blurredBitmap));
   

4. Renderscript is included into support v8 enabling this answer down to api 8. To enable it using gradle include these lines into your gradle file (from this answer)

   defaultConfig {
       ...
       renderscriptTargetApi *your target api*
       renderscriptSupportModeEnabled true
   }
   

5. Result

Just show file name extension from Windows Explorer, after applying the below steps, create a new file, and type your extension as .json

Open Folder Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Appearance and Personalization, and then clicking Folder Options.

Click the View tab, and then, under Advanced settings, clear the Hide extensions for known file types check box, and then click OK

For the given json format as in file ~/my-app/src/db/abc.json:

  [
      {
        "name":"Ankit",
        "id":1
      },
      {
        "name":"Aditi",
        "id":2
      },
      {
        "name":"Avani",
        "id":3
      }
  ]

inorder to import to .js file like ~/my-app/src/app.js:

 const json = require("./db/abc.json");

 class Arena extends React.Component{
   render(){
     return(
       json.map((user)=>
        {
          return(
            <div>{user.name}</div>
          )
        }
       )
      }
    );
   }
 }

 export default Arena;

Output:

Ankit Aditi Avani

I had this issue for longer than I would like to admit.

I simply just needed to run VS as an administrator, rookie mistake on my part...

I tried the first solution and it works but the end user can easily identify that the div's are refreshing as it is fadeIn(), without fade in i tried .toggle().toggle() and it works perfect. you can try like this

$("#panel").toggle().toggle();

it works perfectly for me as i'm developing a messenger and need to minimize and maximize the chat box's and this does it best rather than the above code.

I may be just repeating everyone else but I do have a pretty piece of code that extends the DependencyObject class with a method FindChild() that will get you the child by type and name. Just include and use.

public static class UIChildFinder
{
    public static DependencyObject FindChild(this DependencyObject reference, string childName, Type childType)
    {

Hope you find it useful.

best way to handle this issue is to use a HashSet :

ArrayList<String> listGroupCode = new ArrayList<>();
listGroupCode.add("A");
listGroupCode.add("A");
listGroupCode.add("B");
listGroupCode.add("C");
HashSet<String> set = new HashSet<>(listGroupCode);
ArrayList<String> result = new ArrayList<>(set);

Just print result arraylist and see the result without duplicates :)

If you want to add the row to the end of the grid use the Add() method of the Rows collection...

DataGridView1.Rows.Add(New String(){Value1, Value2, Value3})

If you want to insert the row at a partiular position use the Insert() method of the Rows collection (as GWLlosa also said)...

DataGridView1.Rows.Insert(rowPosition, New String(){value1, value2, value3})

I know you mentioned you weren't doing databinding, but if you defined a strongly-typed dataset with a single datatable in your project, you could use that and get some nice strongly typed methods to do this stuff rather than rely on the grid methods...

DataSet1.DataTable.AddRow(1, "John Doe", true)

git config --global http.sslverify "false"

Node.js remove extension from full path keeping directory

https://stackoverflow.com/a/31615711/895245 for example did path/hello.html -> hello, but if you want path/hello.html -> path/hello, you can use this:

#!/usr/bin/env node
const path = require('path');
const filename = 'path/hello.html';
const filename_parsed = path.parse(filename);
console.log(path.join(filename_parsed.dir, filename_parsed.name));

outputs directory as well:

path/hello

https://stackoverflow.com/a/36099196/895245 also achieves this, but I find this approach a bit more semantically pleasing.

Tested in Node.js v10.15.2.

Specifically regarding "Can I rely completely upon jquery html() method that it'll perform like innerHTML" my answer is NO!

Run this in internet explorer 7 or 8 and you'll see.

jQuery produces bad HTML when setting HTML containing a <FORM> tag nested within a <P> tag where the beginning of the string is a newline!

There are several test cases here and the comments when run should be self explanatory enough. This is quite obscure, but not understanding what's going on is a little disconcerting. I'm going to file a bug report.

Take a look at the INFORMATION_SCHEMA.TABLES table. It contains metadata about all your tables.

Example:

SELECT * FROM `INFORMATION_SCHEMA`.`TABLES`
WHERE TABLE_NAME LIKE 'table1'

The advantage of this over other methods is that you can easily use queries like the one above as subqueries in your other queries.

I know it is late but I just want to share on what I have done for this. I'm not allowed to add another table or trigger so I need to generate it in a single query upon insert. For your case, can you try this query.

CREATE TABLE YOURTABLE(
IDNUMBER VARCHAR(7) NOT NULL PRIMARY KEY,
ENAME VARCHAR(30) not null
);

Perform a select and use this select query and save to the parameter @IDNUMBER

(SELECT IFNULL
     (CONCAT('LHPL',LPAD(
       (SUBSTRING_INDEX
        (MAX(`IDNUMBER`), 'LHPL',-1) + 1), 5, '0')), 'LHPL001')
    AS 'IDNUMBER' FROM YOURTABLE ORDER BY `IDNUMBER` ASC)

And then Insert query will be :

INSERT INTO YOURTABLE(IDNUMBER, ENAME) VALUES 
(@IDNUMBER, 'EMPLOYEE NAME');

The result will be the same as the other answer but the difference is, you will not need to create another table or trigger. I hope that I can help someone that have a same case as mine.

You'd use $_FILES['uploaded_file']['tmp_name'], which is the path where PHP stored the uploaded file (it's a temporary file, removed automatically by PHP when the script ends, unless you've moved/copied it elsewhere).

Assuming your client-side form and server-side upload settings are correct, there's nothing you have to do to "pull in" the upload. It'll just magically be available in that tmp_name path.

Note that you WILL have to validate that the upload actually succeeded, e.g.

if ($_FILES['uploaded_file']['error'] === UPLOAD_ERR_OK) {
    ... attach file to email ...
}

Otherwise you may try to do an attachment with a damaged/partial/non-existent file.

If you ever want to check what locale or character set java is using this is built into the JVM:

java -XshowSettings -version

and it will dump out loads of the settings it's using. This way you can check your LANG and LC_* values are getting picked up correctly.

Remember that

log(n!) = log(1) + log(2) + ... + log(n-1) + log(n)

You can get the upper bound by

log(1) + log(2) + ... + log(n) <= log(n) + log(n) + ... + log(n)
                                = n*log(n)

And you can get the lower bound by doing a similar thing after throwing away the first half of the sum:

log(1) + ... + log(n/2) + ... + log(n) >= log(n/2) + ... + log(n) 
                                       = log(n/2) + log(n/2+1) + ... + log(n-1) + log(n)
                                       >= log(n/2) + ... + log(n/2)
                                        = n/2 * log(n/2) 

The only portable way to achieve consistency between rooms and tags and making sure rooms are never returned after they had been deleted is locking them with SELECT FOR UPDATE.

However in some systems locking is a side effect of concurrency control, and you achieve the same results without specifying FOR UPDATE explicitly.

To solve this problem, Thread 1 should SELECT id FROM rooms FOR UPDATE, thereby preventing Thread 2 from deleting from rooms until Thread 1 is done. Is that correct?

This depends on the concurrency control your database system is using.

• MyISAM in MySQL (and several other old systems) does lock the whole table for the duration of a query.

• In SQL Server, SELECT queries place shared locks on the records / pages / tables they have examined, while DML queries place update locks (which later get promoted to exclusive or demoted to shared locks). Exclusive locks are incompatible with shared locks, so either SELECT or DELETE query will lock until another session commits.

• In databases which use MVCC (like Oracle, PostgreSQL, MySQL with InnoDB), a DML query creates a copy of the record (in one or another way) and generally readers do not block writers and vice versa. For these databases, a SELECT FOR UPDATE would come handy: it would lock either SELECT or the DELETE query until another session commits, just as SQL Server does.

When should one use REPEATABLE_READ transaction isolation versus READ_COMMITTED with SELECT ... FOR UPDATE?

Generally, REPEATABLE READ does not forbid phantom rows (rows that appeared or disappeared in another transaction, rather than being modified)

• In Oracle and earlier PostgreSQL versions, REPEATABLE READ is actually a synonym for SERIALIZABLE. Basically, this means that the transaction does not see changes made after it has started. So in this setup, the last Thread 1 query will return the room as if it has never been deleted (which may or may not be what you wanted). If you don't want to show the rooms after they have been deleted, you should lock the rows with SELECT FOR UPDATE

• In InnoDB, REPEATABLE READ and SERIALIZABLE are different things: readers in SERIALIZABLE mode set next-key locks on the records they evaluate, effectively preventing the concurrent DML on them. So you don't need a SELECT FOR UPDATE in serializable mode, but do need them in REPEATABLE READ or READ COMMITED.

Note that the standard on isolation modes does prescribe that you don't see certain quirks in your queries but does not define how (with locking or with MVCC or otherwise).

When I say "you don't need SELECT FOR UPDATE" I really should have added "because of side effects of certain database engine implementation".

Whenever I have a class that contains a nested class that is of any significant size/complexity, I mark the class as partial and put the nested class in a separate file. I name the file containing the nested class using the rule: [class name].[nested class name].cs.

The following MSDN blog explains using partial classes with nested classes for maintainability: http://blogs.msdn.com/b/marcelolr/archive/2009/04/13/using-partial-classes-with-nested-classes-for-maintainability.aspx

I know this is an old question, but how about just binding to Command if using MVVM?

ex:

<CheckBox Content="Case Sensitive" Command="{Binding bSearchCaseSensitive}"/>

For me it triggers on both Check and Uncheck.

What I usually do is create a delete page that shows a confirmation form if the request method is "GET" and deletes the data if the method was "POST" and the user chose the "Yes" option.

Then, in the page with the delete link, I add an onclick function (or just use the jQuery confirm plugin) that uses AJAX to post to the link, bypassing the confirmation page.

Here's the idea in pseudo code:

delete.php:

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    if ($_POST['confirm'] == 'Yes') {
        delete_record($_REQUEST['id']); // From GET or POST variables
    }
    redirect($_POST['referer']);
}
?>

<form action="delete.php" method="post">
    Are you sure?
    <input type="submit" name="confirm" value="Yes">
    <input type="submit" name="confirm" value="No">

    <input type="hidden" name="id" value="<?php echo $_GET['id']; ?>">
    <input type="hidden" name="referer" value="<?php echo $_SERVER['HTTP_REFERER']; ?>">
</form>

Page with delete link:

<script>
    function confirmDelete(link) {
        if (confirm("Are you sure?")) {
            doAjax(link.href, "POST"); // doAjax needs to send the "confirm" field
        }
        return false;
    }
</script>

<a href="delete.php?id=1234" onclick="return confirmDelete(this);">Delete record</a>

Here's a non-standard but cross-browser method that may be useful if you don't want to pass any arguments:-

Html:

<div onclick=myHandler() id="my element's id">&rarr; Click Here! &larr;</div>

Script:

function myHandler(){
    alert(myHandler.caller.arguments[0].target.id)
}

Just bumped into this post, by getting the same error, trying to test if two variables are both empty (or non-empty). That turns out to be a compound comparison - 7.3. Other Comparison Operators - Advanced Bash-Scripting Guide; and I thought I should note the following:

• I used -e thinking it means "empty" at first; but that means "file exists" - use -z for testing empty variable (string)
• String variables need to be quoted
• For compound logical AND comparison, either:
  • use two tests and && them: [ ... ] && [ ... ]
  • or use the -a operator in a single test: [ ... -a ... ]

Here is a working command (searching through all txt files in a directory, and dumping those that grep finds contain both of two words):

find /usr/share/doc -name '*.txt' | while read file; do \
  a1=$(grep -H "description" $file); \
  a2=$(grep -H "changes" $file); \
  [ ! -z "$a1" -a ! -z "$a2"  ] && echo -e "$a1 \n $a2" ; \
done

Edit 12 Aug 2013: related problem note:

Note that when checking string equality with classic test (single square bracket [), you MUST have a space between the "is equal" operator, which in this case is a single "equals" = sign (although two equals' signs == seem to be accepted as equality operator too). Thus, this fails (silently):

$ if [ "1"=="" ] ; then echo A; else echo B; fi 
A
$ if [ "1"="" ] ; then echo A; else echo B; fi 
A
$ if [ "1"="" ] && [ "1"="1" ] ; then echo A; else echo B; fi 
A
$ if [ "1"=="" ] && [ "1"=="1" ] ; then echo A; else echo B; fi 
A

... but add the space - and all looks good:

$ if [ "1" = "" ] ; then echo A; else echo B; fi 
B
$ if [ "1" == "" ] ; then echo A; else echo B; fi 
B
$ if [ "1" = "" -a "1" = "1" ] ; then echo A; else echo B; fi 
B
$ if [ "1" == "" -a "1" == "1" ] ; then echo A; else echo B; fi 
B

<input type="text" required="true" value="" readonly="true">

This will make a text box in readonly mode, might be helpful in generating passwords and datepickers.

Delete the .git directory in the root-directory of your repository if you only want to delete the git-related information (branches, versions).

If you want to delete everything (git-data, code, etc), just delete the whole directory.

.git directories are hidden by default, so you'll need to be able to view hidden files to delete it.

Here is elegant solution using Kotlin extensions:

data class ApiError(val code: Int, val message: String?) {
    companion object {
        val EMPTY_API_ERROR = ApiError(-1, null)
    }
}

fun Throwable.getApiError(): ApiError? {
    if (this is HttpException) {
        try {
            val errorJsonString = this.response()?.errorBody()?.string()
            return Gson().fromJson(errorJsonString, ApiError::class.java)
        } catch (exception: Exception) {
            // Ignore
        }
    }
    return EMPTY_API_ERROR
}

and usage:

showError(retrofitThrowable.getApiError()?.message)

You can use this script to find dates between two dates. Reference taken from this Article:

DECLARE @StartDateTime DATETIME
DECLARE @EndDateTime DATETIME

SET @StartDateTime = '2015-01-01'
SET @EndDateTime = '2015-01-12';

WITH DateRange(DateData) AS 
(
    SELECT @StartDateTime as Date
    UNION ALL
    SELECT DATEADD(d,1,DateData)
    FROM DateRange 
    WHERE DateData < @EndDateTime
)
SELECT DateData
FROM DateRange
OPTION (MAXRECURSION 0)
GO

The easiest correct way to convert JS Date to SQL datetime format that occur to me is this one. It correctly handles timezone offset.

const toSqlDatetime = (inputDate) => {
    const date = new Date(inputDate)
    const dateWithOffest = new Date(date.getTime() - (date.getTimezoneOffset() * 60000))
    return dateWithOffest
        .toISOString()
        .slice(0, 19)
        .replace('T', ' ')
}

toSqlDatetime(new Date()) // 2019-08-07 11:58:57
toSqlDatetime(new Date('2016-6-23 1:54:16')) // 2016-06-23 01:54:16

Beware that @Paulo Roberto answer will produce incorrect results at the turn on new day (i can't leave comments). For example:

var d = new Date('2016-6-23 1:54:16'),
    finalDate = d.toISOString().split('T')[0]+' '+d.toTimeString().split(' ')[0];
console.log(finalDate); // 2016-06-22 01:54:16 

We've got 22 June instead of 23!

Without using an overlay, you can use pointer-events: none on the div in CSS, but this does not work in IE or Opera.

div.disabled

  pointer-events: none;

  /* for "disabled" effect */

  background: #CCC;
}

This little example shows how the $rootScope emit a event that will be listen by a children scope in another controller.

(function(){


angular
  .module('ExampleApp',[]);

angular
  .module('ExampleApp')
  .controller('ExampleController1', Controller1);

Controller1.$inject = ['$rootScope'];

function Controller1($rootScope) {
  var vm = this, 
      message = 'Hi my children scope boy';

  vm.sayHi = sayHi;

  function sayHi(){
    $rootScope.$broadcast('greeting', message);
  }

}

angular
  .module('ExampleApp')
  .controller('ExampleController2', Controller2);

Controller2.$inject = ['$scope'];

function Controller2($scope) {
  var vm = this;

  $scope.$on('greeting', listenGreeting)

  function listenGreeting($event, message){
    alert(['Message received',message].join(' : '));
  }

}


})();

The answer of @gayathri bottom explain technically the differences of all those methods in the scope angular concept and their implementations $scope and $rootScope.

The name of the array indicates the starting address. Starting address of both namet2 and nameIt2 are different. So the equal to (==) operator checks whether the addresses are the same or not. For comparing two strings, a better way is to use strcmp(), or we can compare character by character using a loop.

Try this:

$(this).hide("slide", { direction: "left" }, 1000);

$(this).show("slide", { direction: "left" }, 1000);

To all the great answers, I want to add a small detail:

If You write plugins (e.g. DLLs or .so libraries to be loaded by a CAD system), then static is a life saver that avoids name collisions like this one:

1. The CAD system loads a plugin A, which has a "const int foo = 42;" in it.
2. The system loads a plugin B, which has "const int foo = 23;" in it.
3. As a result, plugin B will use the value 42 for foo, because the plugin loader will realize, that there is already a "foo" with external linkage.

Even worse: Step 3 may behave differently depending on compiler optimization, plugin load mechanism, etc.

I had this issue once with two helper functions (same name, different behaviour) in two plugins. Declaring them static solved the problem.

It really depends on the database server.

For example, SQL Server 2008 supports a FILESTREAM datatype for exactly this situation.

Other than that, if you use a MemoryStream, it has a ToArray() method that will convert to a byte[] - this can be used for populating a varbinary field..

First you should use print_r($_FILES) to debug, and see what it contains. :

your uploads.php would look like:

//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);

//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];


//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
    //Tells you if its all ok
    echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
    // Connects to your Database
    mysql_connect("localhost", "root", "") or die(mysql_error()) ;
    mysql_select_db("altabotanikk") or die(mysql_error()) ;

    //Writes the information to the database
    mysql_query("INSERT INTO picture (Filename,Description)
    VALUES ('$Filename', '$Description')") ;
} else {
    //Gives and error if its not
    echo "Sorry, there was a problem uploading your file.";
}

Incredibly late but inspired by Homan's brilliantly simple answer, allow me to post a more general solution (general in the sense that Homan's solution crashes on arrays of points with less than 3 vertices):

function smooth(ctx, points)
{
    if(points == undefined || points.length == 0)
    {
        return true;
    }
    if(points.length == 1)
    {
        ctx.moveTo(points[0].x, points[0].y);
        ctx.lineTo(points[0].x, points[0].y);
        return true;
    }
    if(points.length == 2)
    {
        ctx.moveTo(points[0].x, points[0].y);
        ctx.lineTo(points[1].x, points[1].y);
        return true;
    }
    ctx.moveTo(points[0].x, points[0].y);
    for (var i = 1; i < points.length - 2; i ++)
    {
        var xc = (points[i].x + points[i + 1].x) / 2;
        var yc = (points[i].y + points[i + 1].y) / 2;
        ctx.quadraticCurveTo(points[i].x, points[i].y, xc, yc);
    }

If you are doing something like writing HTML and Javascript in a code editor on your personal computer, and testing the output in your browser, you will probably get error messages about Cross Origin Requests. Your browser will render HTML and run Javascript, jQuery, angularJs in your browser without needing a server set up. But many web browsers are programed to watch for cross site attacks, and will block requests. You don't want just anyone being able to read your hard drive from your web browser. You can create a fully functioning web page using Notepad++ that will run Javascript, and frameworks like jQuery and angularJs; and test everything just by using the Notepad++ menu item, RUN, LAUNCH IN FIREFOX. That's a nice, easy way to start creating a web page, but when you start creating anything more than layout, css and simple page navigation, you need a local server set up on your machine.

Here are some options that I use.

1. Test your web page locally on Firefox, then deploy to your host.
2. or: Run a local server

Test on Firefox, Deploy to Host

1. Firefox currently allows Cross Origin Requests from files served from your hard drive
2. Your web hosting site will allow requests to files in folders as configured by the manifest file

Run a Local Server

• Run a server on your computer, like Apache or Python
• Python isn't a server, but it will run a simple server

Run a Local Server with Python

Get your IP address:

• On Windows: Open up the 'Command Prompt'. All Programs, Accessories, Command Prompt
• I always run the Command Prompt as Administrator. Right click the Command Prompt menu item and look for Run As Administrator
• Type the command: ipconfig and hit Enter.
• Look for: IPv4 Address . . . . . . . . 12.123.123.00
• There are websites that will also display your IP address

If you don't have Python, download and install it.

Using the 'Command Prompt' you must go to the folder where the files are that you want to serve as a webpage.

• If you need to get back to the C:\ Root directory - type cd/
• type cd Drive:\Folder\Folder\etc to get to the folder where your .Html file is (or php, etc)
• Check the path. type: path at the command prompt. You must see the path to the folder where python is located. For example, if python is in C:\Python27, then you must see that address in the paths that are listed.
• If the path to the Python directory is not in the path, you must set the path. type: help path and hit Enter. You will see help for path.
• Type something like: path c:\python27 %path%
• %path% keeps all your current paths. You don't want to wipe out all your current paths, just add a new path.
• Create the new path FROM the folder where you want to serve the files.
• Start the Python Server: Type: python -m SimpleHTTPServer port Where 'port' is the number of the port you want, for example python -m SimpleHTTPServer 1337
• If you leave the port empty, it defaults to port 8000
• If the Python server starts successfully, you will see a msg.

Run You Web Application Locally

• Open a browser
• In the address line type: http://your IP address:port
• http://xxx.xxx.x.x:1337 or http://xx.xxx.xxx.xx:8000 for the default
• If the server is working, you will see a list of your files in the browser
• Click the file you want to serve, and it should display.

More advanced solutions

• Install a code editor, web server, and other services that are integrated.

You can install Apache, PHP, Python, SQL, Debuggers etc. all separately on your machine, and then spend lots of time trying to figure out how to make them all work together, or look for a solution that combines all those things.

I like using XAMPP with NetBeans IDE. You can also install WAMP which provides a User Interface for managing and integrating Apache and other services.

Normally this error means that a connection was established with a server but that connection was closed by the remote server. This could be due to a slow server, a problem with the remote server, a network problem, or (maybe) some kind of security error with data being sent to the remote server but I find that unlikely.

Normally a network error will resolve itself given a bit of time, but it sounds like you’ve already given it a bit of time.

cURL sometimes having issue with SSL and SSL certificates. I think that your Apache and/or PHP was compiled with a recent version of the cURL and cURL SSL libraries plus I don't think that OpenSSL was installed in your web server.

Although I can not be certain However, I believe cURL has historically been flakey with SSL certificates, whereas, Open SSL does not.

Anyways, try installing Open SSL on the server and try again and that should help you get rid of this error.

Navigation properties are typically defined as virtual so that they can take advantage of certain Entity Framework functionality such as lazy loading.

If a navigation property can hold multiple entities (as in many-to-many or one-to-many relationships), its type must be a list in which entries can be added, deleted, and updated, such as ICollection.

From a quick glance on MDN I think you may need to include the .js at the end of your file name so the import would read import './course.js' instead of import './course'

Ref: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import

You want to check the settings.py in the INSTALLED_APPS list and make sure all the apps with models are listed in there.

Running makemigrations in the project folder means it will look to update all the tables related to all the apps included in settings.py for the project. Once you include it, makemigrations will automatically include the app (this saves a lot of work so you don't have to run makemigrations app_name for every app in your project/site).

Simply specify the version in your current pom. The version specified here will override other.

Forcing a version
A version will always be honoured if it is declared in the current POM with a particular version - however, it should be noted that this will also affect other poms downstream if it is itself depended on using transitive dependencies.

Run this command:

The current directory is a system-level feature; it returns the directory that the server was launched from. It has nothing to do with the website.

You want HttpRuntime.AppDomainAppPath.

If you're in an HTTP request, you can also call Server.MapPath("~/Whatever").

Use the ensure_ascii=False switch to json.dumps(), then encode the value to UTF-8 manually:

>>> json_string = json.dumps("??? ????", ensure_ascii=False).encode('utf8')
>>> json_string
b'"\xd7\x91\xd7\xa8\xd7\x99 \xd7\xa6\xd7\xa7\xd7\x9c\xd7\x94"'
>>> print(json_string.decode())
"??? ????"

If you are writing to a file, just use json.dump() and leave it to the file object to encode:

with open('filename', 'w', encoding='utf8') as json_file:
    json.dump("??? ????", json_file, ensure_ascii=False)

Caveats for Python 2

For Python 2, there are some more caveats to take into account. If you are writing this to a file, you can use io.open() instead of open() to produce a file object that encodes Unicode values for you as you write, then use json.dump() instead to write to that file:

with io.open('filename', 'w', encoding='utf8') as json_file:
    json.dump(u"??? ????", json_file, ensure_ascii=False)

Do note that there is a bug in the json module where the ensure_ascii=False flag can produce a mix of unicode and str objects. The workaround for Python 2 then is:

with io.open('filename', 'w', encoding='utf8') as json_file:
    data = json.dumps(u"??? ????", ensure_ascii=False)
    # unicode(data) auto-decodes data to unicode if str
    json_file.write(unicode(data))

In Python 2, when using byte strings (type str), encoded to UTF-8, make sure to also set the encoding keyword:

>>> d={ 1: "??? ????", 2: u"??? ????" }
>>> d
{1: '\xd7\x91\xd7\xa8\xd7\x99 \xd7\xa6\xd7\xa7\xd7\x9c\xd7\x94', 2: u'\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4'}

>>> s=json.dumps(d, ensure_ascii=False, encoding='utf8')
>>> s
u'{"1": "\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4", "2": "\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4"}'
>>> json.loads(s)['1']
u'\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4'
>>> json.loads(s)['2']
u'\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4'
>>> print json.loads(s)['1']
??? ????
>>> print json.loads(s)['2']
??? ????

You can also have a look at Enum that implements Comparator.

http://tobega.blogspot.com/2008/05/beautiful-enums.html

e.g.

Collections.sort(myChildren, Child.Order.ByAge.descending());

Other answers have demonstrated the way you should do this. Here's a way you shouldn't:

>>> def foo(counter=[0]):
...   counter[0] += 1
...   print("Counter is %i." % counter[0]);
... 
>>> foo()
Counter is 1.
>>> foo()
Counter is 2.
>>> 

Default values are initialized only when the function is first evaluated, not each time it is executed, so you can use a list or any other mutable object to store static values.

You can do something like that:

$ci = get_instance(); // CI_Loader instance
$ci->load->config('email');
echo $ci->config->item('name');

I might do something like the following. Of course, with the wealth of Collection classes, i can't imagine ever needing to use this in any practical code.

public class Shift {
  public static <T> T[] left (final T... i) {
    if (1 >= i.length) {
      return i;
    }
    final T t = i[0];
    int x = 0;
    for (; x < i.length - 1; x++) {
      i[x] = i[x + 1];
    }
    i[x] = t;
    return i;
  }
}

Called with two arguments, it's a swap.

It can be used as follows:

int x = 1;
int y = 2;
Integer[] yx = Shift.left(x,y);

Alternatively:

Integer[] yx = {x,y};
Shift.left(yx);

Then

x = yx[0];
y = yx[1];

Note: it auto-boxes primitives.

When dealing with marker clusters this one worked for me.

var infowindow = null;

google.maps.event.addListener(marker, "click", function () {

        if (infowindow) {
            infowindow.close();
        }
        var markerMap = this.getMap();
        infowindow = this.info;
        this.info.open(markerMap, this);


    });

Another way is to create functions in global scope. This was necessary for me since it wasn't possible in Angular 1.5 to reach a component's scope.

Example:

angular.module("app", []).component("component", {_x000D_
  controller: ["$window", function($window) {_x000D_
    var self = this;_x000D_
    _x000D_
    self.logg = function() {_x000D_
      console.log("logging!");_x000D_
    };_x000D_
    _x000D_
    $window.angularControllerLogg = self.logg;_x000D_
  }_x000D_
});_x000D_
               _x000D_
window.angularControllerLogg();

You can see if the file is locked by trying to read or lock it yourself first.

Please see my answer here for more information.

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

Got help from this discussion. In my case the

git reset HEAD subby
git commit

worked for me :)

I used part of the method from the solutions above; however, they did not work completely. On the latest version of Andy, this worked for me:

On Andy (Root Shell) [To get, right click the HandyAndy icon and select Term Shell]

Inside the shell, run these commands:

mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd /system/bin
cat sh > su && chmod 4775 su

Then, install SuperSU and install SU binary. This will replace the SU binary we just created. (Optional) Remove SuperSU and install Superuser by CWM. Install the su binary again. Now, root works!

Get a backup copy of the .metadata/.plugin/org.eclipse.core.resources folder, then delete that folder and launch eclipse. That should launch the workspace, but all projects will be gone as org.eclipse.core.resources keeps a list of all projects.

Next, close eclipse properly and copy back org.eclipse.core.resources from back up to .metadata/.plugins/ folder overriding the existing one.

Open eclipse and things should work fine with all your projects back to normal.

Update for angularJS 4:

Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:3000/node_modules/@angular/platform-browser/bundles/platform-browser.umd.js/animations

Solution:

**cli:** (command/terminal)
npm install @angular/animations@latest --save

**systemjs.config.js** (edit file)
'@angular/animations': 'npm:@angular/animations/bundles/animations.umd.js',
'@angular/animations/browser': 'npm:@angular/animations/bundles/animations-browser.umd.js',
'@angular/platform-browser/animations': 'npm:@angular/platform-browser/bundles/platform-browser-animations.umd.js',

**app.module.ts** (edit file)
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
@NgModule({
  imports:      [ BrowserModule,BrowserAnimationsModule ],
...

Here you go:

InputStream is = new ByteArrayInputStream( myString.getBytes() );

Update For multi-byte support use (thanks to Aaron Waibel's comment):

InputStream is = new ByteArrayInputStream(Charset.forName("UTF-16").encode(myString).array());

Please see ByteArrayInputStream manual.

It is safe to use a charset argument in String#getBytes(charset) method above.

After JDK 7+ you can use

java.nio.charset.StandardCharsets.UTF_16

instead of hardcoded encoding string:

InputStream is = new ByteArrayInputStream(StandardCharsets.UTF_16.encode(myString).array());

Just add a div around the container so it looks like:

<div style="background: red;">
  <div class="container marketing">
    <h2 style="padding-top: 60px;"></h2>
  </div>
</div>

this way i follow and its work for me fine, may it will works for you,

<iframe class="img-responsive" src="{{pdfLoc| trustThisUrl }}" ng-style="{
                height: iframeHeight * 0.75 + 'px'
            }" style="width:100%"></iframe>

here trustThisUrl is just filter,

angular.module("app").filter('trustThisUrl', ["$sce", function ($sce) {
        return function (val) {
            return $sce.trustAsResourceUrl(val);
        };
    }]);

My freely available memory profiler MemPro allows you to compare 2 snapshots and gives stack traces for all of the allocations.

What does the assert keyword in Java do?

Let's look at the compiled bytecode.

We will conclude that:

public class Assert {
    public static void main(String[] args) {
        assert System.currentTimeMillis() == 0L;
    }
}

generates almost the exact same bytecode as:

public class Assert {
    static final boolean $assertionsDisabled =
        !Assert.class.desiredAssertionStatus();
    public static void main(String[] args) {
        if (!$assertionsDisabled) {
            if (System.currentTimeMillis() != 0L) {
                throw new AssertionError();
            }
        }
    }
}

where Assert.class.desiredAssertionStatus() is true when -ea is passed on the command line, and false otherwise.

We use System.currentTimeMillis() to ensure that it won't get optimized away (assert true; did).

The synthetic field is generated so that Java only needs to call Assert.class.desiredAssertionStatus() once at load time, and it then caches the result there. See also: What is the meaning of "static synthetic"?

We can verify that with:

javac Assert.java
javap -c -constants -private -verbose Assert.class

With Oracle JDK 1.8.0_45, a synthetic static field was generated (see also: What is the meaning of "static synthetic"?):

static final boolean $assertionsDisabled;
  descriptor: Z
  flags: ACC_STATIC, ACC_FINAL, ACC_SYNTHETIC

together with a static initializer:

 0: ldc           #6                  // class Assert
 2: invokevirtual #7                  // Method java/lang Class.desiredAssertionStatus:()Z
 5: ifne          12
 8: iconst_1
 9: goto          13
12: iconst_0
13: putstatic     #2                  // Field $assertionsDisabled:Z
16: return

and the main method is:

 0: getstatic     #2                  // Field $assertionsDisabled:Z
 3: ifne          22
 6: invokestatic  #3                  // Method java/lang/System.currentTimeMillis:()J
 9: lconst_0
10: lcmp
11: ifeq          22
14: new           #4                  // class java/lang/AssertionError
17: dup
18: invokespecial #5                  // Method java/lang/AssertionError."<init>":()V
21: athrow
22: return

We conclude that:

• there is no bytecode level support for assert: it is a Java language concept
• assert could be emulated pretty well with system properties -Pcom.me.assert=true to replace -ea on the command line, and a throw new AssertionError().

var dt = new Date()  //current date of week
var currentWeekDay = dt.getDay();
var lessDays = currentWeekDay == 0 ? 6 : currentWeekDay-1
var wkStart = new Date(new Date(dt).setDate(dt.getDate()- lessDays));
var wkEnd = new Date(new Date(wkStart).setDate(wkStart.getDate()+6));

This will be useful for any date scenario.

In my case it happened after I converted the whole solution (using an extension called Target Framework Migrator) to 4.6.2 but ended up undoing the changes and going back to 3.5 (solution is versioned by TFS). To solve this, I converted just the problematic project (which was using IIS Express to run) to 4.6.2 and then back to 3.5.

Probably not what you want to hear, but a "feeds" table would be a great middleman for this sort of transaction, giving you a denormalized way of pivoting to all these data with a polymorphic relationship.

You could build it like this:

<?php

Schema::create('feeds', function($table) {
    $table->increments('id');
    $table->timestamps();
    $table->unsignedInteger('user_id');
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->morphs('target'); 
});

Build the feed model like so:

<?php

class Feed extends Eloquent
{
    protected $fillable = ['user_id', 'target_type', 'target_id'];

    public function user()
    {
        return $this->belongsTo('User');
    }

    public function target()
    {
        return $this->morphTo();
    }
}

Then keep it up to date with something like:

<?php

Vote::created(function(Vote $vote) {
    $target_type = 'Vote';
    $target_id   = $vote->id;
    $user_id     = $vote->user_id;

    Feed::create(compact('target_type', 'target_id', 'user_id'));
});

You could make the above much more generic/robust—this is just for demonstration purposes.

At this point, your feed items are really easy to retrieve all at once:

<?php

Feed::whereIn('user_id', $my_friend_ids)
    ->with('user', 'target')
    ->orderBy('created_at', 'desc')
    ->get();

Integer Types:

short            -> signed short
signed short
unsigned short
int              -> signed int
signed int
unsigned int
signed           -> signed int
unsigned         -> unsigned int
long             -> signed long
signed long
unsigned long

Be careful of char:

char  (is signed or unsigned depending on the implmentation)
signed char
unsigned char

use:

import six
if isinstance(obj, six.text_type)

inside the six library it is represented as:

if PY3:
    string_types = str,
else:
    string_types = basestring,

Since Symfony 3.1 you can use JSON Helper http://symfony.com/doc/current/book/controller.html#json-helper

public function indexAction()
{
// returns '{"username":"jane.doe"}' and sets the proper Content-Type header
return $this->json(array('username' => 'jane.doe'));

// the shortcut defines three optional arguments
// return $this->json($data, $status = 200, $headers = array(), $context = array());
}

div tags are used to style the webpage so that it look visually appealing for the users or audience of the website. using container-div in html will make the website look more professional and attractive and therefore more people will want to explore your page.

you can define a custom ScrollView class, & add an interface be called when scrolling like this:

public class ScrollChangeListenerScrollView extends HorizontalScrollView {


private MyScrollListener mMyScrollListener;

public ScrollChangeListenerScrollView(Context context) {
    super(context);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


public void setOnMyScrollListener(MyScrollListener myScrollListener){
    this.mMyScrollListener = myScrollListener;
}


@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
    super.onScrollChanged(l, t, oldl, oldt);
    if(mMyScrollListener!=null){
        mMyScrollListener.onScrollChange(this,l,t,oldl,oldt);
    }

}

public interface MyScrollListener {
    void onScrollChange(View view,int scrollX,int scrollY,int oldScrollX, int oldScrollY);
}

}

Check if JsonProperty attribute is set on the fields that come as null - it could be that they are mapped to different json property-names.

Here is the function which we can use to calculate business days between two date. I'm not using holiday list as it can vary accross country/region.

If we want to use it anyway we can take third argument as list of holiday and before incrementing count we should check that list does not contains d

public static int GetBussinessDaysBetweenTwoDates(DateTime StartDate,   DateTime EndDate)
    {
        if (StartDate > EndDate)
            return -1;

        int bd = 0;

        for (DateTime d = StartDate; d < EndDate; d = d.AddDays(1))
        {
            if (d.DayOfWeek != DayOfWeek.Saturday && d.DayOfWeek != DayOfWeek.Sunday)
                bd++;
        }

        return bd;
    }

I prefer using a separate file for ie rules, as described earlier.

<!--[if IE]><link rel="stylesheet" type="text/css" href="ie-style.css"/><![endif]-->

And inside it you can set up rules for different versions of ie using this:

.abc {...} /* ALL MSIE */
*html *.abc {...} /* MSIE 6 */
*:first-child+html .abc {...} /* MSIE 7 */

This excellent answer to a similar question (that I could not find before, unfortunately) helped me solve the problem.

Copying Content from referenced answer :

SQL Developer will look in the following location in this order for a tnsnames.ora file

$HOME/.tnsnames.ora
$TNS_ADMIN/tnsnames.ora
TNS_ADMIN lookup key in the registry
/etc/tnsnames.ora ( non-windows )
$ORACLE_HOME/network/admin/tnsnames.ora
LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME_KEY
LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME

If your tnsnames.ora file is not getting recognized, use the following procedure:

Define an environmental variable called TNS_ADMIN to point to the folder that contains your tnsnames.ora file.

In Windows, this is done by navigating to Control Panel > System > Advanced system settings > Environment Variables...
In Linux, define the TNS_ADMIN variable in the .profile file in your home directory.

Confirm the os is recognizing this environmental variable

From the Windows command line: echo %TNS_ADMIN%

From linux: echo $TNS_ADMIN

Restart SQL Developer Now in SQL Developer right click on Connections and select New Connection.... Select TNS as connection type in the drop down box. Your entries from tnsnames.ora should now display here.

Refering to Oliver Gierke's hint:

When the manipulation of the persistance.xml does the trick, then you created a normal java-class instead of a entity-class.

When creating a new entity-class then the entry in the persistance.xml should be set by Netbeans (in my case).

But as mentioned by Oliver Gierke you can add the entry later to the persistance.xml (if you created a normal java-class).

Its easy, dont Align it to anything

<Button_x000D_
        android:id="@+id/the_button"_x000D_
        android:layout_width="wrap_content"_x000D_
        android:layout_height="wrap_content" _x000D_
        android:layout_centerInParent="true"_x000D_
        android:text="Centered Button"/>

open looks in the current working directory, which in your case is ~, since you are calling your script from the ~ directory.

You can fix the problem by either

• cding to the directory containing data.csv before executing the script, or

• by using the full path to data.csv in your script, or

• by calling os.chdir(...) to change the current working directory from within your script. Note that all subsequent commands that use the current working directory (e.g. open and os.listdir) may be affected by this.

It turns out, I was using the fetch method incorrectly.

fetch expects two parameters: an endpoint to the API, and an optional object which can contain body and headers.

I was wrapping the intended object within a second object, which did not get me any desired result.

Here's how it looks on a high level:

fetch('API_ENDPOINT', OBJECT)  
  .then(function(res) {
    return res.json();
   })
  .then(function(resJson) {
    return resJson;
   })

I structured my object as such:

var obj = {  
  method: 'POST',
  headers: {

Your application is already running on that port 8080 . Use this code to kill the port and run your code again

sudo lsof -t -i tcp:8080 | xargs kill -9

So I'm not entirely sure why this works, but it saves an image with my plot:

dtf = pd.DataFrame.from_records(d,columns=h)
dtf2.plot()
fig = plt.gcf()
fig.savefig('output.png')

I'm guessing that the last snippet from my original post saved blank because the figure was never getting the axes generated by pandas. With the above code, the figure object is returned from some magic global state by the gcf() call (get current figure), which automagically bakes in axes plotted in the line above.

Read this and try, this will help you:

Table1

column11,column12,column13,column14

Table2

column21,column22,column23,column24


SELECT table1.column11,table1.column12,table2asnew1.column21,table2asnew2.column21 
FROM table1 INNER JOIN table2 AS table2asnew1 ON table1.column11=table2asnew1.column21  INNER TABLE table2 as table2asnew2 ON table1.column12=table2asnew2.column22

table2asnew1 is an instance of table 2 which is matched by table1.column11=table2asnew1.column21

and

table2asnew2 is another instance of table 2 which is matched by table1.column12=table2asnew2.column22

Or, alternatively, you can take a list comprehension approach:

>>> mylis = ['this is test', 'another test']
>>> [item.upper() for item in mylis]
['THIS IS TEST', 'ANOTHER TEST']

Dim arr As Integer() = {1, 2, 3}
Dim newItem As Integer = 4
ReDim Preserve arr (3)
arr(3)=newItem

This is a select statement, so each branch of the case must return something. If you want to perform actions, just use an if.

In stead of replacing text branding, I divided into two rows like in the code below and gave img-responsive class to the image......

<div class="collapse navbar-collapse navbar-ex1-collapse" style="background: #efefef; height:auto;">
  <div class="container" style="margin-bottom:-1px;">
    <div class="row">
      <div class="col-md-3">
        <div id="menubar-logo">
          <a href="index.html"><img src="img/tl_logo.png" class="img-responsive" alt="Triple Luck IT Service Logo"></a>
        </div>
      </div>
      <div class=" col-md-offset-3 col-md-6">

        <ul class="nav navbar-nav">
          <li><a href="index.php" class="active">Home</a></li>
          <li><a href="about_us.php">About Us</a></li>
          <li><a href="contact_us.php">Contact Us</a></li>
        </ul>
      </div>
    </div>
    <!-- end of "row" -->
  </div>
  <!-- end of "container" -->
</div>
<!-- end of "collapse" -->

and in addition,I added the following css codes.......

#menubar-logo img {
  margin-top: 10px;
  margin-bottom: 20px;
  margin-right: 10px;
}

If my code solves your problem, it's my pleasure.....

For those using asyncio, an easy way is to use asyncio.wait_for():

async def my_loop():
    res = False
    while not res:
        res = await do_something()

await asyncio.wait_for(my_loop(), 10)

Right now, you're creating an instance of every type defined in the assembly. You only need to create a single instance of Class1 in order to call the method:

class Program
{
    static void Main(string[] args)
    {
        var DLL = Assembly.LoadFile(@"C:\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\DLL.dll");

        var theType = DLL.GetType("DLL.Class1");
        var c = Activator.CreateInstance(theType);
        var method = theType.GetMethod("Output");
        method.Invoke(c, new object[]{@"Hello"});

        Console.ReadLine();
    }
}

As for me, curly braces serve as a substitution for concatenation, they are quicker to type and code looks cleaner. Remember to use double quotes (" ") as their content is parsed by PHP, because in single quotes (' ') you'll get the literal name of variable provided:

<?php

 $a = '12345';

// This works:
 echo "qwe{$a}rty"; // qwe12345rty, using braces
 echo "qwe" . $a . "rty"; // qwe12345rty, concatenation used

// Does not work:
 echo 'qwe{$a}rty'; // qwe{$a}rty, single quotes are not parsed
 echo "qwe$arty"; // qwe, because $a became $arty, which is undefined

?>

Use attr

$('#abc_frame').attr('src', url)

This way you can get and set every HTML tag attribute. Note that there is also .prop(). See .prop() vs .attr() about the differences. Short version: .attr() is used for attributes as they are written in HTML source code and .prop() is for all that JavaScript attached to the DOM element.

You have to define the text color in the layout *simple_list_item_1* that defines the layout of each of your items.

You set the background color of the LinearLayout and not of the ListView. The background color of the child items of the LinearLayout are transparent by default (in most cases).

And you set the black text color for the TextView that is not part of your ListView. It is an own item (child item of the LinearLayout) here.

Use @Input to pass your data to child components and then use ngOnChanges (https://angular.io/api/core/OnChanges) to see if that @Input changed on the fly.

You can probably start a Service here if you want your Application to run in Background. This is what Service in Android are used for - running in background and doing longtime operations.

UDPATE

You can use START_STICKY to make your Service running continuously.

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    handleCommand(intent);
    // We want this service to continue running until it is explicitly
    // stopped, so return sticky.
    return START_STICKY;
}

One option is to use do.call():

 > do.call(rbind, a)
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5
 [4,]    4    1    2    3    4    5
 [5,]    5    1    2    3    4    5
 [6,]    6    1    2    3    4    5
 [7,]    7    1    2    3    4    5
 [8,]    8    1    2    3    4    5
 [9,]    9    1    2    3    4    5

I wish AngularJS had a built in confirmation dialog. Often, it is nicer to have a customized dialog than using the built in browser one.

I briefly used the twitter bootstrap until it was discontinued with version 6. I looked around for alternatives, but the ones I found were complicated. I decided to try the JQuery UI one.

Here is my sample that I call when I am about to remove something from ng-grid;

    // Define the Dialog and its properties.
    $("<div>Are you sure?</div>").dialog({
        resizable: false,
        modal: true,
        title: "Modal",
        height: 150,
        width: 400,
        buttons: {
            "Yes": function () {
                $(this).dialog('close');
                //proceed with delete...
                /*commented out but left in to show how I am using it in angular
                var index = $scope.myData.indexOf(row.entity);

                $http['delete']('/EPContacts.svc/json/' + $scope.myData[row.rowIndex].RecordID).success(function () { console.log("groovy baby"); });

                $scope.gridOptions.selectItem(index, false);
                $scope.myData.splice(index, 1);
                */
            },
            "No": function () {
                $(this).dialog('close');
                return;
            }
        }
    });

I hope this helps someone. I was pulling my hair out when I needed to upgrade ui-bootstrap-tpls.js but it broke my existing dialog. I came into work this morning, tried a few things and then realized I was over complicating.

Just in case someone stumbles here, I did it this way

  componentDidMount(){
    const node = this.refs.trackerRef;
    node && node.scrollIntoView({block: "end", behavior: 'smooth'})
  }
  componentDidUpdate() {
    const node = this.refs.trackerRef;
    node && node.scrollIntoView({block: "end", behavior: 'smooth'})
  }

  render() {
    return (

      <div>
        {messages.map((msg, index) => {
          return (
            <Message key={index} msgObj={msg}
              {/*<p>some test text</p>*/}
            </Message>
          )
        })}

        <div style={{height: '30px'}} id='#tracker' ref="trackerRef"></div>
      </div>
    )
  }

scrollIntoView is native DOM feature link

It will always shows tracker div

In my case eclipse was using an old settings.xml file.

Sets new value for backgroundPosition on the carousel div when a li in the submenu div is hovered. Removes the backgroundPosition when hovering ends and resets backgroundPosition to old value.

$('#submenu li').hover(function() {
    if ($('#carousel').data('oldbackgroundPosition')==undefined) {
        $('#carousel').data('oldbackgroundPosition', $('#carousel').css('backgroundPosition'));
    }
    $('#carousel').css('backgroundPosition', [enternewvaluehere]);
},
function() {
    var reset = '';
    if ($('#carousel').data('oldbackgroundPosition') != undefined) {
        reset = $('#carousel').data('oldbackgroundPosition');
        $('#carousel').removeData('oldbackgroundPosition');
    }
    $('#carousel').css('backgroundPosition', reset);
});

One thing I have observed regarding this error is that is appears only for the first response from the server, which in case of http should be the handshake response. Once an immediate response is sent from the server to the gateway, if after the main response takes time it does not give an error. The key here is that the first response on a request by a server should be fast.

It could be that the user identity is outdated, especially if you've tried starting a stopped app pool and the next request again fails.

In IIS, go to the Application Pools under the Server, then find the correct Application Pool for your web site, and click on it. On the Advanced Settings menu to the right, select Identity and change it and enter new user and password. Click on your Application Pool again, and select Recycle to restart it.

You can also try looking at the error message in Event Viewer, under Windows Logs, Application, Details tab.

Base url is defined inside Symfony\Component\Routing\RequestContext.

It can be fetched from controller like this:

I've read and tried all the posts and I would like to give an overview of all the solutions. The best way is depending on your requirements. If there are only short snippets that are not longer than a page then go with Insert Object. If the code is longer than one page go with RTF Formatting.

Insert Textbox

• No page break possible
• Spell check available
• Formatting can be ruined very quickly
• In a document with thousands of pages Word 2016 started to make problems. At some point Word always crashed while trying to insert a new Textbox.

Insert Object > Document

• No page break possible
• No spell check
• Formatting and content stays safe

RTF Formatting

• Page breaks possible
• Spell check available
• Annoying line numbers when copying the code again from word
• Online: Planet2b.ca http://www.planetb.ca/syntax-highlight-word
• Offline: Highlight http://www.andre-simon.de/doku/highlight/highlight.php

Or any other wysiwyg-editor/online tool/library to style the code.

All down or doesn't work anymore.

After a lot of trial and error with directory permissions I ended up with an epiphany...there was no space left on the disk's partition. Just wanted to share to make sure nobody else is stupid enough to keep looking for the solution in the wrong direction.

In Linux you can use df -h to check your disk size and free space.

There's always a goto statement, but I would recommend nesting an if with an inverse of the breaking condition.

Use pyplot.text() (import matplotlib.pyplot as plt)

import matplotlib.pyplot as plt

x=[1,2,3]
y=[9,8,7]

plt.plot(x,y)
for a,b in zip(x, y): 
    plt.text(a, b, str(b))
plt.show()

I think in certain cases, you can create a FAKE "list" of items in the database, for example, the merchandise has a few pictures to show its details, you can concatenate all the IDs of pictures split by comma and store the string into the DB, then you just need to parse the string when you need it. I am working on a website now and I am planning to use this way.

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

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

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

I hate using these in-cell formulas and having to fill in a new column, and I finally learned enough to make by own VBA macro to accomplish this effect.

This might not be all that logically different from another answer, but I think the code looks a hell of a lot better:

Dim Switch As Boolean
For Each Cell In Range("B2:B" & ActiveSheet.UsedRange.Rows.Count)
    If Not Cell.Value = Cell.Offset(-1, 0).Value Then Switch = Not (Switch)
    If Switch Then Range("A" & Cell.Row & ":" & Chr(ActiveSheet.UsedRange.Columns.Count + 64) & Cell.Row).Interior.Pattern = xlNone
    If Not Switch Then Range("A" & Cell.Row & ":" & Chr(ActiveSheet.UsedRange.Columns.Count + 64) & Cell.Row).Interior.Color = 14869218
Next

My code here is going by column B, it assumes a header row so it starts at 2, and I use the Chr(x+64) method to get column letters (which won't work past column Z; I haven't yet found a simple-enough method for getting past this).

First, the boolean variable will alternate whenever the value changes to a new one (uses Offset to check cell above), and for each pass the row is checked for either True or False and colors it accordingly.

For a multidimensional array in PHP4 you can use the following addition to the code posted by Udo G:

function js_str($s) {
   return '"'.addcslashes($s, "\0..\37\"\\").'"';
}

function js_array($array, $keys_array) {
  foreach ($array as $key => $value) {
    $new_keys_array = $keys_array;
    $new_keys_array[] = $key;
    if(is_array($value)) {          
      echo 'javascript_array';
      foreach($new_keys_array as $key) {
        echo '["'.$key.'"]';
      }
      echo ' = new Array();';

      js_array($value, $new_keys_array);
    } else {
      echo 'javascript_array';
      foreach($new_keys_array as $key) {
        echo '["'.$key.'"]';
      }
      echo ' = '.js_str($value).";";                        
    }
  } 
}

echo 'var javascript_array = new Array();';
js_array($php_array, array());

You can use Union or Concat, the former removes duplicates, the later doesn't

foreach (var item in List1.Union(List1))
{
   //TODO: Real code goes here
}

foreach (var item in List1.Concat(List1))
{
   //TODO: Real code goes here
}

anyway you have not a unlimited accuracy so C define a constant in this way:

#define PI 3.14159265358979323846

import math.h to use this

This regex selects all spaces, you can use this and replace it with a single space

\s+

example in python

result = re.sub('\s+',' ', data))

The canonic answer, in Python, would be :

s = ''.join(s.splitlines())

It splits the string into lines (letting Python doing it according to its own best practices). Then you merge it. Two possibilities here:

• replace the newline by a whitespace (' '.join())
• or without a whitespace (''.join())

The use operator is for giving aliases to names of classes, interfaces or other namespaces. Most use statements refer to a namespace or class that you'd like to shorten:

use My\Full\Namespace;

is equivalent to:

use My\Full\Namespace as Namespace;
// Namespace\Foo is now shorthand for My\Full\Namespace\Foo

If the use operator is used with a class or interface name, it has the following uses:

// after this, "new DifferentName();" would instantiate a My\Full\Classname
use My\Full\Classname as DifferentName;

// global class - making "new ArrayObject()" and "new \ArrayObject()" equivalent
use ArrayObject;

The use operator is not to be confused with autoloading. A class is autoloaded (negating the need for include) by registering an autoloader (e.g. with spl_autoload_register). You might want to read PSR-4 to see a suitable autoloader implementation.
