Are you ssh'ing to a directory that's inside your work tree? If the root of your ssh mount point doesn't include the .git dir, then zsh won't be able to find git info. Make sure you're mounting something that includes the root of the repo.

As for GIT_DISCOVERY_ACROSS_FILESYSTEM, it doesn't do what you want. Git by default will stop at a filesystem boundary. If you turn that on (and it's just an env var), then git will cross the filesystem boundary and keep looking. However, that's almost never useful, because you'd be implying that you have a .git directory on your local machine that's somehow meant to manage a work tree that's comprised partially of an sshfs mount. That doesn't make much sense.

You can always do this from finder. Simply navigate to the directory above where the mount is and hit the eject icon over the mounted folder, which will have SSHFS in the name (in the finder). A shortcut to open a folder in the finder from the terminal is

open .

which will open up the current directory in a new finder window. Replace "." with your directory of choice.

Crossframe-Scripting is not possible when the two frames have different domains -> Security.

See this: http://javascript.about.com/od/reference/a/frame3.htm

Now to answer your question: there is no solution or work around, you simply should check your website-design why there must be two frames from different domains that changes the url of the other one.

Double click and install the production certificate in your key chain. This might resolve the issue.

Thanks for the great answer @user3136169, here is an example of how that might be done also removing NoneType values.

def regex_filter(val):
    if val:
        mo = re.search(regex,val)
        if mo:
            return True
        else:
            return False
    else:
        return False

df_filtered = df[df['col'].apply(regex_filter)]

Also you can also add regex as an arg:

def regex_filter(val,myregex):
    ...

df_filtered = df[df['col'].apply(res_regex_filter,regex=myregex)]

It can be changed in the $CATALINA_BASE/conf/server.xml in the <Host />. See the Tomcat documentation, specifically the section in regards to the Host container:

Tomcat 6 Configuration

Tomcat 7 Configuration

The default is webapps relative to the $CATALINA_BASE. An absolute pathname can be used.

Hope that helps.

Can't you use

id = id.substring(0, id.length()-4);

And what Eric said, ofcourse.

As of Python 3.5, you can use enhanced generators for async functions.

import asyncio
import datetime

Enhanced generator syntax:

@asyncio.coroutine
def display_date(loop):
    end_time = loop.time() + 5.0
    while True:
        print(datetime.datetime.now())
        if (loop.time() + 1.0) >= end_time:
            break
        yield from asyncio.sleep(1)


loop = asyncio.get_event_loop()
# Blocking call which returns when the display_date() coroutine is done
loop.run_until_complete(display_date(loop))
loop.close()

New async/await syntax:

async def display_date(loop):
    end_time = loop.time() + 5.0
    while True:
        print(datetime.datetime.now())
        if (loop.time() + 1.0) >= end_time:
            break
        await asyncio.sleep(1)


loop = asyncio.get_event_loop()
# Blocking call which returns when the display_date() coroutine is done
loop.run_until_complete(display_date(loop))
loop.close()

public void myfunction(){
        try
        {
            sqlcon.Open();
            SqlCommand cmd = new SqlCommand("sp_laba", sqlcon);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.ExecuteNonQuery();
        }
        catch(Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
        finally
        {
            sqlcon.Close();
        }
}

With localStorage, web applications can store data locally within the user's browser. Before HTML5, application data had to be stored in cookies, included in every server request. Large amounts of data can be stored locally, without affecting website performance. Although localStorage is more modern, there are some pros and cons to both techniques.

Cookies

Pros

• Legacy support (it's been around forever)
• Persistent data
• Expiration dates

Cons

• Each domain stores all its cookies in a single string, which can make parsing data difficult
• Data is unencrypted, which becomes an issue because... ... though small in size, cookies are sent with every HTTP request Limited size (4KB)
• SQL injection can be performed from a cookie

Local storage

Pros

• Support by most modern browsers
• Persistent data that is stored directly in the browser
• Same-origin rules apply to local storage data
• Is not sent with every HTTP request
• ~5MB storage per domain (that's 5120KB)

Cons

• Not supported by anything before: IE 8, Firefox 3.5, Safari 4, Chrome 4, Opera 10.5, iOS 2.0, Android 2.0
• If the server needs stored client information you purposely have to send it.

localStorage usage is almost identical with the session one. They have pretty much exact methods, so switching from session to localStorage is really child's play. However, if stored data is really crucial for your application, you will probably use cookies as a backup in case localStorage is not available. If you want to check browser support for localStorage, all you have to do is run this simple script:

/* 
* function body that test if storage is available
* returns true if localStorage is available and false if it's not
*/
function lsTest(){
    var test = 'test';
    try {
        localStorage.setItem(test, test);
        localStorage.removeItem(test);
        return true;
    } catch(e) {
        return false;
    }
}

/* 
* execute Test and run our custom script 
*/
if(lsTest()) {
    // window.sessionStorage.setItem(name, 1); // session and storage methods are very similar
    window.localStorage.setItem(name, 1);
    console.log('localStorage where used'); // log
} else {
    document.cookie="name=1; expires=Mon, 28 Mar 2016 12:00:00 UTC";
    console.log('Cookie where used'); // log
}

"localStorage values on Secure (SSL) pages are isolated" as someone noticed keep in mind that localStorage will not be available if you switch from 'http' to 'https' secured protocol, where the cookie will still be accesible. This is kind of important to be aware of if you work with secure protocols.

To get data types of all columns:

describe table_name

or just a single column:

describe table_name column_name

If you do the call several times you can use the new method handles introduced in Java 7. Here we go for your method returning a String:

Object obj = new Point( 100, 200 );
String methodName = "toString";  
Class<String> resultType = String.class;

MethodType mt = MethodType.methodType( resultType );
MethodHandle methodHandle = MethodHandles.lookup().findVirtual( obj.getClass(), methodName, mt );
String result = resultType.cast( methodHandle.invoke( obj ) );

System.out.println( result );  // java.awt.Point[x=100,y=200]

Method 2 - Using Element.scrollIntoView:

Note that browser support isn't great for this one

var targetElm = document.querySelector('.boxChild'),  // reference to scroll target_x000D_
    button = document.querySelector('button');        // button that triggers the scroll_x000D_
  _x000D_
// bind "click" event to a button _x000D_
button.addEventListener('click', function(){_x000D_
   targetElm.scrollIntoView()_x000D_
})

.box {_x000D_
  width: 80%;_x000D_
  border: 2px dashed;_x000D_
  height: 180px;_x000D_
  overflow: auto;_x000D_
  scroll-behavior: smooth; /* <-- for smooth scroll */_x000D_
}_x000D_
_x000D_
.boxChild {_x000D_
  margin: 600px 0 300px;_x000D_
  width: 40px;_x000D_
  height: 40px;_x000D_
  background: green;_x000D_
}

<button>Scroll to element</button>_x000D_
<div class='box'>_x000D_
  <div class='boxChild'></div>_x000D_
</div>

Method 3 - Using CSS scroll-behavior:

.box {_x000D_
  width: 80%;_x000D_
  border: 2px dashed;_x000D_
  height: 180px;_x000D_
  overflow-y: scroll;_x000D_
  scroll-behavior: smooth; /* <--- */_x000D_
}_x000D_
_x000D_
#boxChild {_x000D_
  margin: 600px 0 300px;_x000D_
  width: 40px;_x000D_
  height: 40px;_x000D_
  background: green;_x000D_
}

<a href='#boxChild'>Scroll to element</a>_x000D_
<div class='box'>_x000D_
  <div id='boxChild'></div>_x000D_
</div>

If you want the accepted answer to work in JQuery 3 change the code like this:

var scrollItems = menuItems.map(function () {
    var id = $(this).attr("href");
    try {
        var item = $(id);
      if (item.length) {
        return item;
      }
    } catch {}
  });

I also added a try-catch to prevent javascript from crashing if there is no element by that id. Feel free to improve it even more ;)

• XQuery Against the xml Data Type
• General XQuery Use Cases
• XQueries Involving Hierarchy

• XQueries Involving Order

• Anything in Michael Rys blog

Update

My recomendation would be to shred the XML into relations and do searches and joins on the resulted relation, in a set oriented fashion, rather than the procedural fashion of searching specific nodes in the XML. Here is a simple XML query that shreds out the nodes and attributes of interest:

select x.value(N'../../../../@stepId', N'int') as StepID
  , x.value(N'../../@id', N'int') as ComponentID
  , x.value(N'@nom',N'nvarchar(100)') as Nom
  , x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box/components/component/variables/variable') t(x)

However, if you must use an XPath that retrieves exactly the value of interest:

select x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
       variables/variable[@nom="Enabled"]') t(x)

If the stepID and component ID are columns, not variables, the you should use sql:column() instead of sql:variable in the XPath filters. See Binding Relational Data Inside XML Data.

And finaly if all you need is to check for existance you can use the exist() XML method:

select @x.exist(
  N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
      variables/variable[@nom="Enabled" and @valeur="Yes"]') 

Give up and use Perl

Since sed does not cut it, let's just throw the towel and use Perl, at least it is LSB while grep GNU extensions are not :-)

• Print the entire matching part, no matching groups or lookbehind needed:

  cat <<EOS | perl -lane 'print m/\d+/g'
  a1 b2
  a34 b56
  EOS
  

  Output:

  12
  3456
  

• Single match per line, often structured data fields:

  cat <<EOS | perl -lape 's/.*?a(\d+).*/$1/g'
  a1 b2
  a34 b56
  EOS
  

  Output:

  1
  34
  

  With lookbehind:

  cat <<EOS | perl -lane 'print m/(?<=a)(\d+)/'
  a1 b2
  a34 b56
  EOS
  

• Multiple fields:

  cat <<EOS | perl -lape 's/.*?a(\d+).*?b(\d+).*/$1 $2/g'
  a1 c0 b2 c0
  a34 c0 b56 c0
  EOS
  

  Output:

  1 2
  34 56
  

• Multiple matches per line, often unstructured data:

  cat <<EOS | perl -lape 's/.*?a(\d+)|.*/$1 /g'
  a1 b2
  a34 b56 a78 b90
  EOS
  

  Output:

  1 
  34 78
  

  With lookbehind:

  cat EOS<< | perl -lane 'print m/(?<=a)(\d+)/g'
  a1 b2
  a34 b56 a78 b90
  EOS
  

  Output:

  1
  3478
  

Your code should be something like

require_once('class.twitter.php');

$t = new twitter;
$t->username = 'user';
$t->password = 'password';

$data = $t->publicTimeline();

Yes. You know that you can put any Object into the Object parameter of most JOptionPane.showXXX methods, and often that Object happens to be a JPanel.

In your situation, perhaps you could use a JPanel that has several JTextFields in it:

import javax.swing.*;

public class JOptionPaneMultiInput {
   public static void main(String[] args) {
      JTextField xField = new JTextField(5);
      JTextField yField = new JTextField(5);

      JPanel myPanel = new JPanel();
      myPanel.add(new JLabel("x:"));
      myPanel.add(xField);
      myPanel.add(Box.createHorizontalStrut(15)); // a spacer
      myPanel.add(new JLabel("y:"));
      myPanel.add(yField);

      int result = JOptionPane.showConfirmDialog(null, myPanel, 
               "Please Enter X and Y Values", JOptionPane.OK_CANCEL_OPTION);
      if (result == JOptionPane.OK_OPTION) {
         System.out.println("x value: " + xField.getText());
         System.out.println("y value: " + yField.getText());
      }
   }
}

Use DATE_ADD function

DATE_ADD(datecolumn, INTERVAL 30 MINUTE);

check that you entered a variable as argument with the '$' symbol

var matches = [];
$(".className:checked").each(function() {
    matches.push(this.value);
});

Just create a data.frame with 0 length variables

eg

nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)

## 'data.frame':    0 obs. of  3 variables:
##  $ x: num 
##  $ y: int 
##  $ z: Factor w/ 0 levels: 

or to create a data.frame with 5 columns named a,b,c,d,e

nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))

In addition, if you want to refer to the root directory, you can use:

/

Which will refer to the root. So, let's say we're in a file that's nested within a few levels of folders and you want to go back to the main index.html:

<a href="/index.html">My Index Page</a>

Robert is spot-on with further relative path explanations.

a='hello world'
map(lambda x:x, a)

['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd']

An easy way is using function “map()”.

/* =============================
 * Disable / Enable Page Scroll
 * when Bootstrap Modals are
 * shown / hidden
 * ============================= */

function preventDefault(e) {
  e = e || window.event;
  if (e.preventDefault)
      e.preventDefault();
  e.returnValue = false;  
}

function theMouseWheel(e) {
  preventDefault(e);
}

function disable_scroll() {
  if (window.addEventListener) {
      window.addEventListener('DOMMouseScroll', theMouseWheel, false);
  }
  window.onmousewheel = document.onmousewheel = theMouseWheel;
}

function enable_scroll() {
    if (window.removeEventListener) {
        window.removeEventListener('DOMMouseScroll', theMouseWheel, false);
    }
    window.onmousewheel = document.onmousewheel = null;  
}

$(function () {
  // disable page scrolling when modal is shown
  $(".modal").on('show', function () { disable_scroll(); });
  // enable page scrolling when modal is hidden
  $(".modal").on('hide', function () { enable_scroll(); });
});

Try

if (this.onsubmit instanceof Function) {
    // do stuff;
}

After looking on Super User I found this question which explains how to do this with the shortcut on the start screen. Similarly you can do the same when Visual Studio is pinned to the task bar. In either location:

1. Right click the Visual Studio icon
2. Go to Properties
3. Under the Shortcut tab select Advanced
4. Check Run as administrator

Unlike in Windows 7 this only works if you launch the application from the shortcut you changed. After updating both Visual Studio shortcuts it seems to also work when you open a solution file from Explorer.

Update Warning: It looks like one of the major flaws in running Visual Studio with elevated permissions is since Explorer isn't running with them as well you can't drag and drop files into Visual Studio for editing. You need to open them through the file open dialog. Nor can you double click any file associated to Visual Studio and have it open in Visual Studio (aside from solutions it seems) because you'll get an error message saying There was a problem sending the command to the program. Once I uncheck to always start with elevated permissions (using VSCommands) then I'm able to open files directly and drop them into an open instance of Visual Studio.

Update For The Daring: Despite there being no UI to turn off UAC like in the past, that I saw at least, you can still do so through the registry. The key to edit is:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
EnableLUA - DWORD 1-Enabled, 0-Disabled

After changing this Windows will prompt you to restart. Once restarted you'll be back to everything running with admin permissions if you're an admin. The issues I reported above are now gone as well.

Just use --repo option for git push command. Like this:

$ git push --repo https://name:[email protected]/name/repo.git

Using following commands to uninstall :

npm uninstall -g @angular/cli
npm cache clean --force

To verify: ng --version /* You will get the error message, then u have uninstalled */

Using following commands to re-install :

npm install -g @angular/cli

Notes : - Using --force for clean all the caches - On Windows run this using administrator - On Mac use sudo ($ sudo <command>)

• If you are using npm>5 you may need to use cache verify instead. ($ npm cache verify)

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

In the examples below the client is the browser and the server is the webserver hosting the website.

Before you can understand these technologies, you have to understand classic HTTP web traffic first.

Regular HTTP:

1. A client requests a webpage from a server.
2. The server calculates the response
3. The server sends the response to the client.

Ajax Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server at regular intervals (e.g. 0.5 seconds).
3. The server calculates each response and sends it back, just like normal HTTP traffic.

Ajax Long-Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server.
3. The server does not immediately respond with the requested information but waits until there's new information available.
4. When there's new information available, the server responds with the new information.
5. The client receives the new information and immediately sends another request to the server, re-starting the process.

HTML5 Server Sent Events (SSE) / EventSource:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection to the server.

3. The server sends an event to the client when there's new information available.

   • Real-time traffic from server to client, mostly that's what you'll need
   • You'll want to use a server that has an event loop
   • Connections with servers from other domains are only possible with correct CORS settings
   • If you want to read more, I found these very useful: (article), (article), (article), (tutorial).

HTML5 Websockets:

1. A client requests a webpage from a server using regular http (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection with the server.

3. The server and the client can now send each other messages when new data (on either side) is available.

   • Real-time traffic from the server to the client and from the client to the server
   • You'll want to use a server that has an event loop
   • With WebSockets it is possible to connect with a server from another domain.
   • It is also possible to use a third party hosted websocket server, for example Pusher or others. This way you'll only have to implement the client side, which is very easy!
   • If you want to read more, I found these very useful: (article), (article) (tutorial).

Comet:

Comet is a collection of techniques prior to HTML5 which use streaming and long-polling to achieve real time applications. Read more on wikipedia or this article.

Now, which one of them should I use for a realtime app (that I need to code). I have been hearing a lot about websockets (with socket.io [a node.js library]) but why not PHP ?

You can use PHP with WebSockets, check out Ratchet.

Use a+ to open a file for reading, writing as well as create it if it doesn't exist.

a+ Opens a file for both appending and reading. The file pointer is at the end of the file if the file exists. The file opens in the append mode. If the file does not exist, it creates a new file for reading and writing. -Python file modes

with open('"File.txt', 'a+') as file:
    print(file.readlines())
    file.write("test")

Note: opening file in a with block makes sure that the file is properly closed at the block's end, even if an exception is raised on the way. It's equivalent to try-finally, but much shorter.

The only difference is that CHARACTER VARYING is more human friendly than VARCHAR

The reason why you are getting the compilation error is, you are trying to access the session in declaration block (<%! %>) where it is not available. All the implicit objects of jsp are available in service method only. Code of declarative blocks goes outside the service method.

I'd advice you to use EL. It is a simplified approach.

${sessionScope.username} would give you the desired output.

The os.makedirs function does this. Try the following:

import os
import errno

filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
    try:
        os.makedirs(os.path.dirname(filename))
    except OSError as exc: # Guard against race condition
        if exc.errno != errno.EEXIST:
            raise

with open(filename, "w") as f:
    f.write("FOOBAR")

The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.

In Python 3.2+, there is a more elegant way that avoids the race condition above:

import os

filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
    f.write("FOOBAR")

Writing a decorator that works with and without parameter is a challenge because Python expects completely different behavior in these two cases! Many answers have tried to work around this and below is an improvement of answer by @norok2. Specifically, this variation eliminates the use of locals().

Following the same example as given by @norok2:

import functools

def multiplying(f_py=None, factor=1):
    assert callable(f_py) or f_py is None
    def _decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            return factor * func(*args, **kwargs)
        return wrapper
    return _decorator(f_py) if callable(f_py) else _decorator


@multiplying
def summing(x): return sum(x)

print(summing(range(10)))
# 45


@multiplying()
def summing(x): return sum(x)

print(summing(range(10)))
# 45


@multiplying(factor=10)
def summing(x): return sum(x)

print(summing(range(10)))
# 450

Play with this code.

The catch is that the user must supply key,value pairs of parameters instead of positional parameters and the first parameter is reserved.

I wrote a Tester class which can test the performance:

public class Tester
{
    public static void main(String[] args)
    {
        String text = "";

        int loopCount = 10000000;
        long startTime, endTime, duration1, duration2;

        startTime = System.nanoTime();
        for (int i = 0; i < loopCount; i++) {
            text.equals("");
        }
        endTime = System.nanoTime();
        duration1 = endTime - startTime;
        System.out.println(".equals(\"\") duration " +": \t" + duration1);

        startTime = System.nanoTime();
        for (int i = 0; i < loopCount; i++) {
            text.isEmpty();
        }
        endTime = System.nanoTime();
        duration2 = endTime - startTime;
        System.out.println(".isEmpty() duration "+": \t\t" + duration2);

        System.out.println("isEmpty() to equals(\"\") ratio: " + ((float)duration2 / (float)duration1));
    }
}

I found that using .isEmpty() took around half the time of .equals("").

In most modern browsers, you can now specify:

<table>
 <colgroup>
  <col width="100px" />
  <col width="200px" />
  <col width="145px" />
 </colgroup>
 <thead>
  <tr>
   <th>My 100px header</th>
   <th>My 200px header</th>
   <th>My 145px header</th>
  </tr>
 </thead>
 <tbody>
  <td>100px is all you get - anything more hides due to overflow.</td>
  <td>200px is all you get - anything more hides due to overflow.</td>
  <td>100px is all you get - anything more hides due to overflow.</td>
 </tbody>
</table>

Then if you apply the styles from the posts above, as follows:

table {
    table-layout: fixed; /* This enforces the "col" widths. */
}
table th, table td {
    overflow: hidden;
    white-space: nowrap;
}

The result gives you nicely hidden overflow throughout the table. Works in latest Chrome, Safari, Firefox and IE. I haven't tested in IE prior to 9 - but my guess is that it will work back as far as 7, and you might even get lucky enough to see 5.5 or 6 support. ;)

Since String is a bridge type for NSString, the "old" methods should work, but it's not clear how - e.g., this doesn't work either (doesn't appear to be valid syntax):

 let x = str.substringWithRange(NSMakeRange(0, 3))

To me, that is the really interesting part of your question. String is bridged to NSString, so most NSString methods do work directly on a String. You can use them freely and without thinking. So, for example, this works just as you expect:

// delete all spaces from Swift String stateName
stateName = stateName.stringByReplacingOccurrencesOfString(" ", withString:"")

But, as so often happens, "I got my mojo workin' but it just don't work on you." You just happened to pick one of the rare cases where a parallel identically named Swift method exists, and in a case like that, the Swift method overshadows the Objective-C method. Thus, when you say str.substringWithRange, Swift thinks you mean the Swift method rather than the NSString method — and then you are hosed, because the Swift method expects a Range<String.Index>, and you don't know how to make one of those.

The easy way out is to stop Swift from overshadowing like this, by casting explicitly:

let x = (str as NSString).substringWithRange(NSMakeRange(0, 3))

Note that no significant extra work is involved here. "Cast" does not mean "convert"; the String is effectively an NSString. We are just telling Swift how to look at this variable for purposes of this one line of code.

The really weird part of this whole thing is that the Swift method, which causes all this trouble, is undocumented. I have no idea where it is defined; it is not in the NSString header and it's not in the Swift header either.

For anyone that wants to do this using Python, and be able to export all tables without predefinining field names etc, I wrote a short script for this the other day, hope someone finds it useful:

from contextlib import closing
from datetime import datetime
import json
import MySQLdb
DB_NAME = 'x'
DB_USER = 'y'
DB_PASS = 'z'

def get_tables(cursor):
    cursor.execute('SHOW tables')
    return [r[0] for r in cursor.fetchall()] 

def get_rows_as_dicts(cursor, table):
    cursor.execute('select * from {}'.format(table))
    columns = [d[0] for d in cursor.description]
    return [dict(zip(columns, row)) for row in cursor.fetchall()]

def dump_date(thing):
    if isinstance(thing, datetime):
        return thing.isoformat()
    return str(thing)


with closing(MySQLdb.connect(user=DB_USER, passwd=DB_PASS, db=DB_NAME)) as conn, closing(conn.cursor()) as cursor:
    dump = {}
    for table in get_tables(cursor):
        dump[table] = get_rows_as_dicts(cursor, table)
    print(json.dumps(dump, default=dump_date, indent=2))

An anonymous namespace makes the enclosed variables, functions, classes, etc. available only inside that file. In your example it's a way to avoid global variables. There is no runtime or compile time performance difference.

There isn't so much an advantage or disadvantage aside from "do I want this variable, function, class, etc. to be public or private?"

Safe Methods : Get Resource/No modification in resource
Idempotent : No change in resource status if requested many times
Unsafe Methods : Create or Update Resource/Modification in resource
Non-Idempotent : Change in resource status if requested many times

According to your requirement :

1) For safe and idempotent operation (Fetch Resource) use --------- GET METHOD
2) For unsafe and non-idempotent operation (Insert Resource) use--------- POST METHOD
3) For unsafe and idempotent operation (Update Resource) use--------- PUT METHOD
3) For unsafe and idempotent operation (Delete Resource) use--------- DELETE METHOD

try :%s/\^M// At least this worked for me.

Looks fine to me:

You're sure you didn't on the settings globally or something? This is a clean installation of the beta on Windows 7. The developer tools report that the page is defaulting to IE9 Standard Mode.

Well, you can't check if it's down after the event, but you can check if it's Up... If it's up.. it means that no longer is down :P lol

So the user presses the button down (onMouseDown event) ... and after that, you check if is up (onMouseUp). While it's not up, you can do what you need.

This is what I've been using for development:

<?xml version="1.0" ?>
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>

This is a very liberal approach, but is fine for my application.

As others have pointed out below, beware the risks of this.

I have found that I can also generate exactly that error output on a perfectly working piece of code by attempting to use the profiler on it.

Note that this was on Windows (where the forking is a bit less elegant).

I was running:

python -m profile -o output.pstats <script> 

And found that removing the profiling removed the error and placing the profiling restored it. Was driving me batty too because I knew the code used to work. I was checking to see if something had updated pool.py... then had a sinking feeling and eliminated the profiling and that was it.

Posting here for the archives in case anybody else runs into it.

OkHttp Version:3.11.0 or higher

From okhttp source code:

/**
 * Sets the default connect timeout for new connections. A value of 0 means no timeout,
 * otherwise values must be between 1 and {@link Integer#MAX_VALUE} when converted to
 * milliseconds.
 *
 * <p>The connectTimeout is applied when connecting a TCP socket to the target host.
 * The default value is 10 seconds.
 */
public Builder connectTimeout(long timeout, TimeUnit unit) {
    connectTimeout = checkDuration("timeout", timeout, unit);
    return this;
}

unit can be any value of below

TimeUnit.NANOSECONDS
TimeUnit.MICROSECONDS
TimeUnit.MILLISECONDS
TimeUnit.SECONDS
TimeUnit.MINUTES
TimeUnit.HOURS
TimeUnit.DAYS

example code

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(5000, TimeUnit.MILLISECONDS)/*timeout: 5 seconds*/
    .build();

String url = "https://www.google.com";
Request request = new Request.Builder()
    .url(url)
    .build();

try {
    Response response = client.newCall(request).execute();
} catch (IOException e) {
    e.printStackTrace();
}

Updated

I have add new API to OkHttp from version 3.12.0, you can set timeout like this:

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(Duration.ofSeconds(5)) // timeout: 5 seconds
    .build();

NOTE: This requires API 26+ so if you support older versions of Android, continue to use (5, TimeUnit.SECONDS).

This query uses the Group By and and Having clauses to allow you to select (locate and list out) for each duplicate record. The As clause is a convenience to refer to Quantity in the select and Order By clauses, but is not really part of getting you the duplicate rows.

Select
    Title,
    Count( Title ) As [Quantity]
   From
    Training
   Group By
    Title
   Having 
    Count( Title ) > 1
   Order By
    Quantity desc

In very simple terms, I like to think about it like this:

• real is the actual amount of time it took to run the command (as if you had timed it with a stopwatch)

• user and sys are how much 'work' the CPU had to do to execute the command. This 'work' is expressed in units of time.

Generally speaking:

• user is how much work the CPU did to run to run the command's code
• sys is how much work the CPU had to do to handle 'system overhead' type tasks (such as allocating memory, file I/O, ect.) in order to support the running command

Since these last two times are counting 'work' done, they don't include time a thread might have spent waiting (such as waiting on another process or for disk I/O to finish).

real, however, is a measure of actual runtime and not 'work', so it does include any time spent waiting.

"Class.forName()" returns the Class-Type for the given name. "newInstance()" does return an instance of this class.

On the type you can't call directly any instance methods but can only use reflection for the class. If you want to work with an object of the class you have to create an instance of it (same as calling "new MyClass()").

Example for "Class.forName()"

Class myClass = Class.forName("test.MyClass");
System.out.println("Number of public methods: " + myClass.getMethods().length);

Example for "Class.forName().newInstance()"

MyClass myClass = (MyClass) Class.forName("test.MyClass").newInstance();
System.out.println("String representation of MyClass instance: " + myClass.toString());

The header function is used to send HTTP response headers back to the user (i.e. you cannot use it to create request headers.

May I ask why are you doing this? Why simulate a POST request when you can just right there and then act on the data someway? I'm assuming of course script.php resides on your server.

To create a POST request, open a up a TCP connection to the host using fsockopen(), then use fwrite() on the handler returned from fsockopen() with the same values you used in the header functions in the OP. Alternatively, you can use cURL.

public static long byteArrayToLong(byte[] bytes) {
    return ((long) (bytes[0]) << 56)
            + (((long) bytes[1] & 0xFF) << 48)
            + ((long) (bytes[2] & 0xFF) << 40)
            + ((long) (bytes[3] & 0xFF) << 32)
            + ((long) (bytes[4] & 0xFF) << 24)
            + ((bytes[5] & 0xFF) << 16)
            + ((bytes[6] & 0xFF) << 8)
            + (bytes[7] & 0xFF);
}

convert bytes array (long is 8 bytes) to long

It will be $_COOKIE['CaptchaResponseValue'], not $_COOKIE('CaptchaResponseValue')

You can make all warnings being treated as such using -Wno-error. You can make specific warnings being treated as such by using -Wno-error=<warning name> where <warning name> is the name of the warning you don't want treated as an error.

If you want to entirely disable all warnings, use -w (not recommended).

In the context of Drupal, the difference will depend whether clean URLs are on or not.

With them off, $_SERVER['REQUEST_URI'] will have the full path of the page as called w/ /index.php, while $_GET["q"] will just have what is assigned to q.

With them on, they will be nearly identical w/o other arguments, but $_GET["q"] will be missing the leading /. Take a look towards the end of the default .htaccess to see what is going on. They will also differ if additional arguments are passed into the page, eg when a pager is active.

SELECT
    *
FROM
    (SELECT MAX(PriceDate) AS MaxP, Partid FROM MyPrices GROUP BY Partid) MaxP 
    JOIN
    MyPrices MP On MaxP.Partid = MP.Partid AND MaxP.MaxP = MP.PriceDate
    JOIN
    MyParts P ON MP.Partid = P.Partid

You to get the latest pricedate for partid first (a standard aggregate), then join it back to get the prices (which can't be in the aggregate), followed by getting the part details.

Mine didn't work because I created it from a button from the documentation. I went again to the project and created another OAuthClientID. It worked. Yes, be careful about the extra spaces on right and left too.

I had to use a slightly extended version @Erwin Brandstetter used:

DO
$do$
DECLARE
  _db TEXT := 'some_db';
  _user TEXT := 'postgres_user';
  _password TEXT := 'password';
BEGIN
  CREATE EXTENSION IF NOT EXISTS dblink; -- enable extension 
  IF EXISTS (SELECT 1 FROM pg_database WHERE datname = _db) THEN
    RAISE NOTICE 'Database already exists';
  ELSE
    PERFORM dblink_connect('host=localhost user=' || _user || ' password=' || _password || ' dbname=' || current_database());
    PERFORM dblink_exec('CREATE DATABASE ' || _db);
  END IF;
END
$do$

I had to enable the dblink extension, plus i had to provide the credentials for dblink. Works with Postgres 9.4.

One-liner: re.match(r"pattern", string) # No need to compile

import re
>>> if re.match(r"hello[0-9]+", 'hello1'):
...     print('Yes')
... 
Yes

You can evalute it as bool if needed

>>> bool(re.match(r"hello[0-9]+", 'hello1'))
True

I would say everything probably works except that the column idx doesn't actually exist in the table you're selecting from. Maybe you meant to select from @Practitioner:

WHILE (@i <= (SELECT MAX(idx) FROM @Practitioner))

because that's defined in the code above like that:

DECLARE @Practitioner TABLE (
    idx smallint Primary Key IDENTITY(1,1)
    , PractitionerId int
)

JSONObject site = (JSONObject)jsonSites.get(i); // Exception happens here.

The return type of jsonSites.get(i) is JSONArray not JSONObject. Because sites have two '[', two means there are two arrays here.

1. = 0 means that a function is pure virtual and you cannot instantiate an object from this class. You need to derive from it and implement this method
2. = delete means that the compiler will not generate those constructors for you. AFAIK this is only allowed on copy constructor and assignment operator. But I am not too good at the upcoming standard.

Server.MapPath specifies the relative or virtual path to map to a physical directory.

• Server.MapPath(".")¹ returns the current physical directory of the file (e.g. aspx) being executed
• Server.MapPath("..") returns the parent directory
• Server.MapPath("~") returns the physical path to the root of the application
• Server.MapPath("/") returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

An example:

Let's say you pointed a web site application (http://www.example.com/) to

C:\Inetpub\wwwroot

and installed your shop application (sub web as virtual directory in IIS, marked as application) in

D:\WebApps\shop

For example, if you call Server.MapPath() in following request:

http://www.example.com/shop/products/GetProduct.aspx?id=2342

then:

• Server.MapPath(".")¹ returns D:\WebApps\shop\products
• Server.MapPath("..") returns D:\WebApps\shop
• Server.MapPath("~") returns D:\WebApps\shop
• Server.MapPath("/") returns C:\Inetpub\wwwroot
• Server.MapPath("/shop") returns D:\WebApps\shop

If Path starts with either a forward slash (/) or backward slash (\), the MapPath() returns a path as if Path was a full, virtual path.

If Path doesn't start with a slash, the MapPath() returns a path relative to the directory of the request being processed.

Note: in C#, @ is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.

Footnotes

1. Server.MapPath(null) and Server.MapPath("") will produce this effect too.

Adding to the many answers, my problem stemmed from wanting to use the docker's ruby as a base, but then using rbenv on top. This screws up a lot of things.

I fixed it in this case by:

• The Gemfile.lock version did need updating - changing the "BUNDLED WITH" to the latest version did at one point change the error message, so may have been required
• in .bash_profile or .bashrc, unsetting the environment variables:

unset GEM_HOME
unset BUNDLE_PATH

After that, rbenv worked fine. Not sure how those env vars were getting loaded in the first place...

cat dump.txt | head -16224 | tail -258

should do the trick. The downside of this approach is that you need to do the arithmetic to determine the argument for tail and to account for whether you want the 'between' to include the ending line or not.

I enjoy the classic "what's the difference between a LinkedList and an ArrayList (or between a linked list and an array/vector) and why would you choose one or the other?"

The kind of answer I hope for is one that includes discussion of:

• insertion performance
• iteration performance
• memory allocation/reallocation impact
• impact of removing elements from the beginning/middle/end
• how knowing (or not knowing) the maximum size of the list can affect the decision

What about this. Seems to give better performance.

byte[] bytes = new byte[1000];

StringBuilder x = new StringBuilder();

int numRead = 0;
while ((numRead = is.read(bytes)) >= 0) {
    x.append(new String(bytes, 0, numRead));
}

Edit: Actually this sort of encompasses both steelbytes and Maurice Perry's

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

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

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

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

nav.service.ts

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

components.ts

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

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

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

This will list out your local comment history (not yet pushed) with corresponding message

There are a couple issues here. First, you need to make sure to bind your JSON object back to the model in the controller. This is done by changing

data: JSON.stringify(usersRoles),

to

data: { model: JSON.stringify(usersRoles) },

Secondly, you aren't binding types correctly with your jquery call. If you remove

contentType: "application/json; charset=utf-8",

it will inherently bind back to a string.

All together, use the first ActionResult method and the following jquery ajax call:

    jQuery.ajax({
        type: "POST",
        url: "@Url.Action("AddUser")",
        dataType: "json",
        data: { model: JSON.stringify(usersRoles) },
        success: function (data) { alert(data); },
        failure: function (errMsg) {
        alert(errMsg);
        }
   });

You can just concatenate the strings and build a command line.

std::string command = a + ' ' + b + " > " + c;
system(command.c_str());

You don't need any extra libraries for this.

Add android:fitsSystemWindows="true" to the layout, and this layout will resize.

I'd start by not calling it list, since that's the name of the constructor for Python's built in list type.

But once you've renamed it to cities or something, you'd do:

print(cities[0][0], cities[1][0])
print(cities[0][1], cities[1][1])

Try below code :

Assign the path of the folder to variable FolderPath before running the below code.

Sub sample()

    Dim FolderPath As String, path As String, count As Integer
    FolderPath = "C:\Documents and Settings\Santosh\Desktop"

    path = FolderPath & "\*.xls"

    Filename = Dir(path)

    Do While Filename <> ""
       count = count + 1
        Filename = Dir()
    Loop

    Range("Q8").Value = count
    'MsgBox count & " : files found in folder"
End Sub

You can still get not-a-number (NaN) values from simple arithmetic involving inf:

>>> 0 * float("inf")
nan

Note that you will normally not get an inf value through usual arithmetic calculations:

>>> 2.0**2
4.0
>>> _**2
16.0
>>> _**2
256.0
>>> _**2
65536.0
>>> _**2
4294967296.0
>>> _**2
1.8446744073709552e+19
>>> _**2
3.4028236692093846e+38
>>> _**2
1.157920892373162e+77
>>> _**2
1.3407807929942597e+154
>>> _**2
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
OverflowError: (34, 'Numerical result out of range')

The inf value is considered a very special value with unusual semantics, so it's better to know about an OverflowError straight away through an exception, rather than having an inf value silently injected into your calculations.

Okey so thanks to @bploat and the link to http://www.codingexplorer.com/nsuserdefaults-a-swift-introduction/

I've found that the answer is quite simple for some basic string storage.

let defaults = NSUserDefaults.standardUserDefaults()

// Store
defaults.setObject("theGreatestName", forKey: "username")

// Receive
if let name = defaults.stringForKey("username")
{
    print(name)
    // Will output "theGreatestName"
}

I've summarized it here http://ridewing.se/blog/save-local-data-in-swift/

I figured I'd leave this here for those upgrading to Turbolinks 5: the easiest way to fix your code is to go from:

var ready;
ready = function() {
  // Your JS here
}
$(document).ready(ready);
$(document).on('page:load', ready)

to:

var ready;
ready = function() {
  // Your JS here
}
$(document).on('turbolinks:load', ready);

I followed the following steps and it worked for me.

For Rails4:

So, what you're wanting is an inner join, so you really should just use the joins predicate:

  Foo.joins(:bar)

  Select * from Foo Inner Join Bars ...

But, for the record, if you want a "NOT NULL" condition simply use the not predicate:

Foo.includes(:bar).where.not(bars: {id: nil})

Select * from Foo Left Outer Join Bars on .. WHERE bars.id IS NOT NULL

Note that this syntax reports a deprecation (it talks about a string SQL snippet, but I guess the hash condition is changed to string in the parser?), so be sure to add the references to the end:

Foo.includes(:bar).where.not(bars: {id: nil}).references(:bar)

DEPRECATION WARNING: It looks like you are eager loading table(s) (one of: ....) that are referenced in a string SQL snippet. For example:

Post.includes(:comments).where("comments.title = 'foo'")

Currently, Active Record recognizes the table in the string, and knows to JOIN the comments table to the query, rather than loading comments in a separate query. However, doing this without writing a full-blown SQL parser is inherently flawed. Since we don't want to write an SQL parser, we are removing this functionality. From now on, you must explicitly tell Active Record when you are referencing a table from a string:

Post.includes(:comments).where("comments.title = 'foo'").references(:comments)

Go to Phone Settings --> Developer Options --> Simulate Secondary Displays and turn it to None. If you don't see Developer Options in the settings menu (it should be at the bottom, go Settings ==> About phone and tap on the Build number a lot of times)

run single test –by filename–

Actually, one can also run a single mocha test by filename (not just by „it()-string-grepping“) if you remove the glob pattern (e.g. ./test/**/*.spec.js) from your mocha.opts, respectively create a copy, without:

node_modules/.bin/mocha --opts test/mocha.single.opts test/self-test.spec.js

Here's my mocha.single.opts (it's only different in missing the aforementioned glob line)

--require ./test/common.js
--compilers js:babel-core/register
--reporter list
--recursive

Background: While you can override the various switches from the opts-File (starting with --) you can't override the glob. That link also has some explanations.

Hint: if node_modules/.bin/mocha confuses you, to use the local package mocha. You can also write just mocha, if you have it installed globally.

And if you want the comforts of package.json: Still: remove the **/*-ish glob from your mocha.opts, insert them here, for the all-testing, leave them away for the single testing:

"test": "mocha ./test/**/*.spec.js",
"test-watch": "mocha -R list -w ./test/**/*.spec.js",
"test-single": "mocha $1",
"test-single-watch": "mocha -R list -w $1",

usage:

> npm run test

respectively

> npm run test-single -- test/ES6.self-test.spec.js 

(mind the --!)

A faster way is to use javascript directly, eg.

var parent = $(innerdiv.get(0).parentNode.parentNode.parentNode);

This runs significantly faster on my browser than chaining jQuery .parent() calls.

See: http://jsperf.com/jquery-get-3rd-level-parent

This is relatively new to C# which makes it easy for us to call the functions with respect to the null or non-null values in method chaining.

old way to achieve the same thing was:

var functionCaller = this.member;
if (functionCaller!= null)
    functionCaller.someFunction(var someParam);

and now it has been made much easier with just:

member?.someFunction(var someParam);

I strongly recommend this doc page.

I noticed following line from error.

exact fetch returns more than requested number of rows

That means Oracle was expecting one row but It was getting multiple rows. And, only dual table has that characteristic, which returns only one row.

Later I recall, I have done few changes in dual table and when I executed dual table. Then found multiple rows.

So, I truncated dual table and inserted only row which X value. And, everything working fine.

To expand on @Steve Roberts answer.

My username is of the form "domain\username" - including the slash in the proxy configuration resulted in a forward slash appearing. So entering this:

npm config set proxy "http://domain\username:password@servername:port/"

I also had to URL encode my domain\user string, however, I have a space inside my username so I put a + to encode the space URL encoding, but it would get double encoded as %2B (which is the URL encoding for the plus sign, however the URL encoding for a space is %20), so I had to instead do the following:

npm command

// option one 
// it works for some packages
npm config set http_proxy "http://DOMAIN%5Cuser+name:[email protected]:port"
npm config set proxy "http://DOMAIN%5Cuser+name:[email protected]:port"

// option two
// it works best for me
// please notice that I actually used a space 
// instead of URL encode it with '+', '%20 ' OR %2B (plus url encoded)
npm config set http_proxy "http://DOMAIN%5Cuser name:[email protected]:port"
npm config set proxy "http://DOMAIN%5Cuser name:[email protected]:port"

// option two (B) as of 2019-06-01
// no DOMAIN
// instead of URL encode it with '+', '%20 ' OR %2B (plus url encoded)
npm config set http_proxy "http://user name:[email protected]:port"
npm config set proxy "http://user name:[email protected]:port"

troubleshooting npm config

I used the npm config list to get the parsed values that I had set above, and that is how I found out about the double encoding. Weird.

Essentially you must figure out the following requirements:

1. Is a DOMAIN string required for authentication
2. Do you need to encode special characters?
   • Spaces and at (@) signs are specially challenging

Regards.

WINDOWS ENVIRONMENT VARIABLES (CMD Prompt)

Update

Turns out that even with the above configurations, I still had some issues with some packages/scripts that use Request - Simplified HTTP client internally to download stuff. So, as the above readme explained, we can specify environment variables to set the proxy on the command line, and Request will honor those values.

Then, after (and I am reluctant to admit this) several tries (more like days), of trying to set the environment variables I finally succeeded with the following guidelines:

rem notice that the value after the = has no quotations
rem    - I believe that if quotations are placed after it, they become
rem    part of the value, you do not want that
rem notice that there is no space before or after the = sign
rem     - if you leave a space before it, you will be declaring a variable 
rem     name that includes such space, you do not want to do that
rem     - if you leave a space after it, you will be including the space
rem     as part of the value, you do not want that either
rem looks like there is no need to URL encode stuff in there
SET HTTP_PROXY=http://DOMAIN\user name:[email protected]:port
SET HTTPS_PROXY=http://DOMAIN\user name:[email protected]:port

cntlm

I used the above technique for a few weeks, untill I realized the overhead of updating my password across all the tools that needed the proxy setup.

Besides npm, I also use:

• bower
• vagrant
  • virtual box (running linux)
  • apt-get [linux]
• git
• vscode
• brackets
• atom
• tsd

cntlm Setup Steps

So, I installed cntlm. Setting cntlm is pretty stright forward, you look for the ini file @ C:\Program Files\Cntlm\cntlm.ini

1. Open C:\Program Files\Cntlm\cntlm.ini (you may need admin rights)
2. look for Username and Domain lines (line 8-9 I think)
   • add your username
   • add your domain

3. On cmd prompt run:

   cd C:\Program Files\Cntlm\
   cntlm -M
   cntlm -H  
   

   • you will be asked for the password:

    cygwin warning:
      MS-DOS style path detected: C:\Program Files\Cntlm\cntlm.ini
      Preferred POSIX equivalent is: /Cntlm/cntlm.ini
      CYGWIN environment variable option "nodosfilewarning" turns off this warning.
      Consult the user's guide for more details about POSIX paths:
        http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
    Password:
   

4. The output you get from cntlm -H will look something like:

   PassLM          561DF6AF15D5A5ADG  
   PassNT          A1D651A5F15DFA5AD  
   PassNTLMv2      A1D65F1A65D1ASD51  # Only for user 'user name', domain 'DOMAIN'
   

   • It is recomended that you use PassNTLMv2 so add a # before line PassLM and PassNT or do not use them
5. Paste the output from cntlm -H on the ini file replacing the lines for PassLM, PassNT and PassNTMLv2, or comment the original lines and add yours.
6. Add your Proxy servers. If you do not know what the proxy server is... Do what I did, I looked for my proxy auto-config file by looking for the AutoConfigURL Registry key in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings. Navigate to that url and look through the code which happens to be JavaScript.
7. Optionaly you can change the port where cntlm listens to by changing the Listen #### line, where #### is the port number.

Setup NPM with cntlm

So, you point npm to your cntml proxy, you can use the ip, I used localhost and the default port for cntlm 3128 so my proxy url looks like this

http://localhost:3128

With the proper command:

npm config set proxy http://localhost:3128

Is a lot simpler. You setup all your tools with that same url, and you only update the password on one place. Life is so much simpler not.

Must Setup The npm CA certificate

From the npm documentation ca

If your corporate proxy is intercepting https connections with its own Self Signed Certificate, this is a must to avoid npm config set strict-ssl false (big no-no).

Basic steps

1. Get the certificate from your browser (Chromes works well). Export it as Base-64 encoded X.509 (.CER)
2. Replace new lines with \n
3. Edit your .npmrc add a line ca[]="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"

Issues

I have noticed tha sometimes npm kind of hangs, so I stop (sometimes forcefully) cntlm and restart it.

int.from_bytes( bytes, byteorder, *, signed=False )

doesn't work with me I used function from this website, it works well

https://coderwall.com/p/x6xtxq/convert-bytes-to-int-or-int-to-bytes-in-python

def bytes_to_int(bytes):
    result = 0
    for b in bytes:
        result = result * 256 + int(b)
    return result

def int_to_bytes(value, length):
    result = []
    for i in range(0, length):
        result.append(value >> (i * 8) & 0xff)
    result.reverse()
    return result

I usually start out with some combination of:

typeof(obj)
class(obj)
sapply(obj, class)
sapply(obj, attributes)
attributes(obj)
names(obj)

as appropriate based on what's revealed. For example, try with:

obj <- data.frame(a=1:26, b=letters)
obj <- list(a=1:26, b=letters, c=list(d=1:26, e=letters))
data(cars)
obj <- lm(dist ~ speed, data=cars)

..etc.

If obj is an S3 or S4 object, you can also try methods or showMethods, showClass, etc. Patrick Burns' R Inferno has a pretty good section on this (sec #7).

EDIT: Dirk and Hadley mention str(obj) in their answers. It really is much better than any of the above for a quick and even detailed peek into an object.

What you want can be achieved by modifying the hosts file through Fiddler 2 application.

Follow these steps:

1. Install Fiddler2

2. Navigate to Fiddler2 menu:- Tools > HOSTS.. (Click to select)

3. Add a line like this:-

   localhost:8080 www.mydomainname.com

4. Save the file & then checkout www.mydomainname.com in browser.

Also make sure your code doesn't have true for setBlockNetworkLoads

webView.getSettings().setBlockNetworkLoads (false);

The easy method that will work even in corrupted setup environment is :

To download ez_setup.py and run it using command line

python ez_setup.py

If the PATH value would be too long after your user's PATH variable has been concatenated onto the environment PATH variable, Windows will silently fail to concatenate the user PATH variable.

This can easily happen after new software is installed and adds something to PATH, thereby breaking existing installed software. Windows fail!

The best fix is to edit one of the PATH variables in the Control Panel and remove entries you don't need. Then open a new CMD window and see if all entries are shown in "echo %PATH%".

We have our Create/Alter scripts under source control. As for the database itself, when you have hundreds of tables and a lot of processing data every minutes, it would be CPU and HDD killer to version all the database. That's why backup is still, according to me, the best way to control your data.

Too late to answer, but an iterative approach sounds easy here:

1) for a set of n elements, get the value of 2^n. There will be 2^n no.of subsets. (2^n because each element can be either present(1) or absent(0). So for n elements there will be 2^n subsets. ). Eg:
for 3 elements, say {a,b,c}, there will be 2^3=8 subsets

2) Get a binary representation of 2^n. Eg:
8 in binary is 1000

3) Go from 0 to (2^n - 1). In each iteration, for each 1 in the binary representation, form a subset with elements that correspond to the index of that 1 in the binary representation. Eg:

For the elements {a, b, c}
000 will give    {}
001 will give    {c}
010 will give    {b}
011 will give    {b, c}
100 will give    {a}
101 will give    {a, c}
110 will give    {a, b}
111 will give    {a, b, c}

4) Do a union of all the subsets thus found in step 3. Return. Eg:
Simple union of above sets!

You could use jQuery and do it as such way

$("li:last-child").addClass("someClass");

Yes! exit(). It's in <cstdlib>.

Although Android can't find and connect to ad-hoc networks it sure can connect to Access Points. So as a work-around you can turn your Wireless Card into an Access Point using, for example, Connectify.

array=(z 'b c'); { set "${array[@]}"; printf '%s\n' "$@"; } \
    | sort \
    | mapfile -t array; declare -p array
declare -a array=([0]="b c" [1]="z")

• Open an inline function {...} to get a fresh set of positional arguments (e.g. $1, $2, etc).
• Copy the array to the positional arguments. (e.g. set "${array[@]}" will copy the nth array argument to the nth positional argument. Note the quotes preserve whitespace that may be contained in an array element).
• Print each positional argument (e.g. printf '%s\n' "$@" will print each positional argument on its own line. Again, note the quotes preserve whitespace that may be contained in each positional argument).
• Then sort does its thing.
• Read the stream into an array with mapfile (e.g. mapfile -t array reads each line into the variable array and the -t ignores the \n in each line).
• Dump the array to show its been sorted.

As a function:

set +m
shopt -s lastpipe

sort_array() { 
    declare -n ref=$1
    set "${ref[@]}"
    printf '%s\n' "$@"
    | sort \
    | mapfile -t $ref
}

then

array=(z y x); sort_array array; declare -p array
declare -a array=([0]="x" [1]="y" [2]="z")

I look forward to being ripped apart by all the UNIX gurus! :)

Why not simply:

if (typeof myObject.myProperty == "undefined") alert("myProperty is not defined!");

Or if you expect a specific type:

if (typeof myObject.myProperty != "string") alert("myProperty has wrong type or does not exist!");

.before and .after

Use modern vanilla JS! Way better/cleaner than previously. No need to reference a parent.

const div1 = document.getElementById("div1");
const div2 = document.getElementById("div2");
const div3 = document.getElementById("div3");

div2.after(div1);
div2.before(div3);

One more way of running an R script from the command line would be:

R < scriptName.R --no-save  

or with --save.

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String

If you want to run a few scripts, you can use Set-executionpolicy -ExecutionPolicy Unrestricted and then reset with Set-executionpolicy -ExecutionPolicy Default.

Note that execution policy is only checked when you start its execution (or so it seems) and so you can run jobs in the background and reset the execution policy immediately.

# Check current setting
Get-ExecutionPolicy

# Disable policy
Set-ExecutionPolicy -ExecutionPolicy Unrestricted
# Choose [Y]es

Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 example.com | tee ping__example.com.txt }
Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 google.com  | tee ping__google.com.txt  }

# Can be run immediately
Set-ExecutionPolicy -ExecutionPolicy Default
# [Y]es

Transient variables in Java are never serialized.

Use the library ngx-print.

Installing:

yarn add ngx-print
or
npm install ngx-print --save

Change your module:

import {NgxPrintModule} from 'ngx-print';
...
imports: [
    NgxPrintModule,
...

Template:

<div id="print-section">
  // print content
</div>
<button ngxPrint printSectionId="print-section">Print</button>

Another way would be to use the apply() function.

If you have the data.frame

df <- data.frame (var1 = c(1:7,NA),
                  var2 = c(1,2,1,3,4,NA,NA,9),
                  var3 = c(NA)
                  )

then you can use apply() to see which columns fulfill your condition and so you can simply do the same subsetting as in the answer by Musa, only with an apply approach.

> !apply (is.na(df), 2, all)
 var1  var2  var3 
 TRUE  TRUE FALSE 

> df[, !apply(is.na(df), 2, all)]
  var1 var2
1    1    1
2    2    2
3    3    1
4    4    3
5    5    4
6    6   NA
7    7   NA
8   NA    9

Nowadays (2016) in Chrome Dev Tools console, you can quickly execute this function below to show all event listeners that have been attached to an element.

getEventListeners(document.querySelector('your-element-selector'));

Are you sure you want to use __getattribute__? What are you actually trying to achieve?

The easiest way to do what you ask is:

class D(object):
    def __init__(self):
        self.test = 20
        self.test2 = 21

    test = 0

or:

class D(object):
    def __init__(self):
        self.test = 20
        self.test2 = 21

    @property
    def test(self):
        return 0

Edit: Note that an instance of D would have different values of test in each case. In the first case d.test would be 20, in the second it would be 0. I'll leave it to you to work out why.

Edit2: Greg pointed out that example 2 will fail because the property is read only and the __init__ method tried to set it to 20. A more complete example for that would be:

class D(object):
    def __init__(self):
        self.test = 20
        self.test2 = 21

    _test = 0

    def get_test(self):
        return self._test

    def set_test(self, value):
        self._test = value

    test = property(get_test, set_test)

Obviously, as a class this is almost entirely useless, but it gives you an idea to move on from.

Since an example of Apache FastDateFormat(click for the documentations of versions:2.6and3.5) is missing here, I am adding one for those who may need it. The key here is the pattern ZZ(2 capital Zs).

import java.text.ParseException
import java.util.Date;
import org.apache.commons.lang3.time.FastDateFormat;
public class DateFormatTest throws ParseException {
    public static void main(String[] args) {
        String stringDateFormat = "yyyy-MM-dd'T'HH:mm:ssZZ";
        FastDateFormat fastDateFormat = FastDateFormat.getInstance(stringDateFormat);
        System.out.println("Date formatted into String:");
        System.out.println(fastDateFormat.format(new Date()));
        String stringFormattedDate = "2016-11-22T14:30:14+05:30";
        System.out.println("String parsed into Date:");
        System.out.println(fastDateFormat.parse(stringFormattedDate));
    }
}

Here is the output of the code:

Date formatted into String:
2016-11-22T14:52:17+05:30
String parsed into Date:
Tue Nov 22 14:30:14 IST 2016

Note: The above code is of Apache Commons' lang3. The class org.apache.commons.lang.time.FastDateFormat does not support parsing, and it supports only formatting. For example, the output of the following code:

import java.text.ParseException;
import java.util.Date;
import org.apache.commons.lang.time.FastDateFormat;
public class DateFormatTest {
    public static void main(String[] args) throws ParseException {
        String stringDateFormat = "yyyy-MM-dd'T'HH:mm:ssZZ";
        FastDateFormat fastDateFormat = FastDateFormat.getInstance(stringDateFormat);
        System.out.println("Date formatted into String:");
        System.out.println(fastDateFormat.format(new Date()));
        String stringFormattedDate = "2016-11-22T14:30:14+05:30";
        System.out.println("String parsed into Date:");
        System.out.println(fastDateFormat.parseObject(stringFormattedDate));
    }
}

will be this:

Date formatted into String:
2016-11-22T14:55:56+05:30
String parsed into Date:
Exception in thread "main" java.text.ParseException: Format.parseObject(String) failed
    at java.text.Format.parseObject(Format.java:228)
    at DateFormatTest.main(DateFormatTest.java:12)

The var keyword in C#'s main benefit is to enhance readability, not functionality. Technically, the var keywords allows for some other unlocks (e.g. use of anonymous objects), but that seems to be outside the scope of this question. Every variable declared with the var keyword has a type. For instance, you'll find that the following code outputs "String".

var myString = "";
Console.Write(myString.GetType().Name);

Furthermore, the code above is equivalent to:

String myString = "";
Console.Write(myString.GetType().Name);

The var keyword is simply C#'s way of saying "I can figure out the type for myString from the context, so don't worry about specifying the type."

var myVariable = (MyType)null or MyType myVariable = null should work because you are giving the C# compiler context to figure out what type myVariable should will be.

For more information:

• How to initialize var?
• http://msdn.microsoft.com/en-us/library/bb397696.aspx

The other answers sufficiently answer the question, but I thought I would share some additional information. Others describe the "DESCRIBE table" syntax in order to get the table information. If you want to get the information in the same format, but without using DESCRIBE, you could do:

SELECT column_name as COLUMN_NAME, nullable || '       ' as BE_NULL,
  SUBSTR(data_type || '(' || data_length || ')', 0, 10) as TYPE
 FROM all_tab_columns WHERE table_name = 'TABLENAME';

Probably doesn't matter much, but I wrote it up earlier and it seems to fit.

String.Join(" ", myList) or String.Join(" ", myList.ToArray()). The first argument is the separator between the substrings.

var myList = new List<String> { "foo","bar","baz"};
Console.WriteLine(String.Join("-", myList)); // prints "foo-bar-baz"

Depending on your version of .NET you might need to use ToArray() on the list first..

So the way I would solve this problem is to make sure the two datetimes are in the right timezone.

I can see that you are using datetime.now() which will return the systems current time, with no tzinfo set.

tzinfo is the information attached to a datetime to let it know what timezone it is in. If you are using naive datetime you need to be consistent through out your system. I would highly recommend only using datetime.utcnow()

seeing as somewhere your are creating datetime that have tzinfo associated with them, what you need to do is make sure those are localized (has tzinfo associated) to the correct timezone.

Take a look at Delorean, it makes dealing with this sort of thing much easier.

It is session-based, when set the way you did in your question.

https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html

According to this, FOREIGN_KEY_CHECKS is "Both" for scope. This means it can be set for session:

SET FOREIGN_KEY_CHECKS=0;

or globally:

SET GLOBAL FOREIGN_KEY_CHECKS=0;

Another simple way:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).Select    
Selection.EntireRow.Delete

or simpler:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).EntireRow.Delete

I find the dict literal d = {'one': '1'} to be much more readable, your defining data, rather than assigning things values and sending them to the dict() constructor.

On the other hand i have seen people mistype the dict literal as d = {'one', '1'} which in modern python 2.7+ will create a set.

Despite this i still prefer to all-ways use the set literal because i think its more readable, personal preference i suppose.

Things seems a little confused in the code in your question, so I am going to give you an example of what I think you are try to do.

First considerations are about mixing HTML, Javascript and CSS:

Why is using onClick() in HTML a bad practice?

Unobtrusive Javascript

Inline Styles vs Classes

I will be removing inline content and splitting these into their appropriate files.

Next, I am going to go with the "click" event and displose of the "change" event, as it is not clear that you want or need both.

Your function changeBackground sets both the backround color and the text color to the same value (your text will not be seen), so I am caching the color value as we don't need to look it up in the DOM twice.

CSS

#TheForm {
    margin-left: 396px;
}
#submitColor {
    margin-left: 48px;
    margin-top: 5px;
}

HTML

<form id="TheForm">
    <input id="color" type="text" />
    <br/>
    <input id="submitColor" value="Submit" type="button" />
</form>
<span id="coltext">This text should have the same color as you put in the text box</span>

Javascript

function changeBackground() {
    var color = document.getElementById("color").value; // cached

    // The working function for changing background color.
    document.bgColor = color;

    // The code I'd like to use for changing the text simultaneously - however it does not work.
    document.getElementById("coltext").style.color = color;
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

Color Values

CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).

Hex values are written as 3 double digit numbers, starting with a # sign.

Update: as pointed out by @Ian

Hex can be either 3 or 6 characters long

Source: W3C

Numerical color values

The format of an RGB value in hexadecimal notation is a ‘#’ immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.

Here is an alternative function that will check that your input is a valid CSS Hex Color, it will set the text color only or throw an alert if it is not valid.

For regex testing, I will use this pattern

/^#(?:[0-9a-f]{3}){1,2}$/i

but if you were regex matching and wanted to break the numbers into groups then you would require a different pattern

function changeBackground() {
    var color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i;

    if (rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Hex Color");
    }
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

On jsfiddle

Here is a further modification that will allow colours by name along with by hex.

function changeBackground() {
    var names = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "Darkorange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Grey", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGrey", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"],
        color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i,
        formattedName = color.charAt(0).toUpperCase() + color.slice(1).toLowerCase();

    if (names.indexOf(formattedName) !== -1 || rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Color");
    }
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

On jsfiddle

I think it is fine because I've seen many people doing this way.

If you are just defining the event handler within the directive, you do not have to define it on the scope, though. Following would be fine.

myApp.directive('clickme', function() {
  return function(scope, element, attrs) {
    var clickingCallback = function() {
      alert('clicked!')
    };
    element.bind('click', clickingCallback);
  }
});

for me, it didn't work without specifying the MIME in web.config, under <system.webServer><staticContent>

<mimeMap fileExtension=".ico" mimeType="image/ico" />

I have an application that I am developing that is laid out similar with Tabs in the Action Bar that launches fragments, some of these Fragments have multiple embedded Fragments within them.

I was getting the same error when I tried to run the application. It seems like if you instantiate the Fragments within the xml layout after a tab was unselected and then reselected I would get the inflator error.

I solved this replacing all the fragments in xml with Linearlayouts and then useing a Fragment manager/ fragment transaction to instantiate the fragments everything seems to working correctly at least on a test level right now.

I hope this helps you out.

Linq With Or Condition by using Lambda expression you can do as below

DataTable dtEmp = new DataTable();

dtEmp.Columns.Add("EmpID", typeof(int));
dtEmp.Columns.Add("EmpName", typeof(string));
dtEmp.Columns.Add("Sal", typeof(decimal));
dtEmp.Columns.Add("JoinDate", typeof(DateTime));
dtEmp.Columns.Add("DeptNo", typeof(int));

dtEmp.Rows.Add(1, "Rihan", 10000, new DateTime(2001, 2, 1), 10);
dtEmp.Rows.Add(2, "Shafi", 20000, new DateTime(2000, 3, 1), 10);
dtEmp.Rows.Add(3, "Ajaml", 25000, new DateTime(2010, 6, 1), 10);
dtEmp.Rows.Add(4, "Rasool", 45000, new DateTime(2003, 8, 1), 20);
dtEmp.Rows.Add(5, "Masthan", 22000, new DateTime(2001, 3, 1), 20);


var res2 = dtEmp.AsEnumerable().Where(emp => emp.Field<int>("EmpID")
            == 1 || emp.Field<int>("EmpID") == 2);

foreach (DataRow row in res2)
{
    Label2.Text += "Emplyee ID: " + row[0] + "   &   Emplyee Name: " + row[1] + ",  ";
}

You can also use Tab Layout with custom tab view to achieve this.

Should do it

You may also want to use hasOwnProperty in the loop.

for (var prop in obj) {
    if (obj.hasOwnProperty(prop)) {
        switch (prop) {
            // obj[prop] has the value
        }
    }
}

node.js is single-threaded which means your script will block whether you want it or not. Remember that V8 (Google's Javascript engine that node.js uses) compiles Javascript into machine code which means that most basic operations are really fast and looping through an object with 100 keys would probably take a couple of nanoseconds?

However, if you do a lot more inside the loop and you don't want it to block right now, you could do something like this

switch (prop) {
    case 'Timestamp':
        setTimeout(function() { ... }, 5);
        break;
    case 'Start_Value':
        setTimeout(function() { ... }, 10);
        break;
}

If your loop is doing some very CPU intensive work, you will need to spawn a child process to do that work or use web workers.

For a start simply add the following to your application.properties file

spring.security.user.name=user
spring.security.user.password=pass

NB: with no double quote

Run your application and enter the credentials (user, pass)

I was doing some volume rendering in octave (matlab clone) and building my 3D arrays (ie an array of 2d slices) using

buffer=zeros(1,512*512*512,"uint16");
vol=reshape(buffer,512,512,512);

Memory consumption seemed to be efficient. (can't say the same for the subsequent speed of computations :^)

public: for the accessibility across all the classes, just like the methods present in the interface

static: as interface cannot have an object, the interfaceName.variableName can be used to reference it or directly the variableName in the class implementing it.

final: to make them constants. If 2 classes implement the same interface and you give both of them the right to change the value, conflict will occur in the current value of the var, which is why only one time initialization is permitted.

Also all these modifiers are implicit for an interface, you dont really need to specify any of them.

Odd errors like "inappropriate ioctl for device" are usually a result of checking $! at some point other than just after a system call failed. If you'd show your code, I bet someone would rapidly point out your error.

You can limit your textview's number of characters and add (...) after the text. Suppose You need to show 5 letters only and thereafter you need to show (...), Just do the following :

String YourString = "abcdefghijk";

if(YourString.length()>5){

YourString  =  YourString.substring(0,4)+"...";

your_text_view.setText(YourString);
}else{

 your_text_view.setText(YourString); //Dont do any change

}

a little hack ^_^. Though its not a good solution. But a work around which worked for me :D

EDIT: I have added check for less character as per your limited no. of characters.

Aside from using %, age of empires III to lower case is age of empires iii so your query should be:

select *
from games
where lower(title) like 'age of empires iii%'

Start with the use of tabs - the \t character modifier. It will advance to a fixed location (columns, terminal lingo).

However, it doesn't help if there are differences of more than the column width (4 characters, if I recall correctly).

To fix that, write your "OK/NOK" stuff using a fixed number of tabs (5? 6?, try it). Then return (\r) without new-lining, and write your message.

I hade the same problem with a jQuery Dialog.

Why destroy the instance if you just want to remove previous data ?

function clearEditor(id)
{
  var instance = CKEDITOR.instances[id];
  if(instance)
  {
    instance.setData( '' );
  }
}

Maybe a DNS issue?

Try your URL against this code:

$_h = curl_init();
curl_setopt($_h, CURLOPT_HEADER, 1);
curl_setopt($_h, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($_h, CURLOPT_HTTPGET, 1);
curl_setopt($_h, CURLOPT_URL, 'YOUR_URL' );
curl_setopt($_h, CURLOPT_DNS_USE_GLOBAL_CACHE, false );
curl_setopt($_h, CURLOPT_DNS_CACHE_TIMEOUT, 2 );

var_dump(curl_exec($_h));
var_dump(curl_getinfo($_h));
var_dump(curl_error($_h)); 

Try using a format file since your data file only has 4 columns. Otherwise, try OPENROWSET or use a staging table.

myTestFormatFiles.Fmt may look like:

This tutorial on skipping a column with BULK INSERT may also help.

Your statement then would look like:

USE xta9354
GO
BULK INSERT xta9354.dbo.Students
    FROM 'd:\userdata\xta9_Students.txt' 
    WITH (FORMATFILE = 'C:\myTestFormatFiles.Fmt')

DECLARE @sql VARCHAR(MAX)
SET @sql=''
SELECT @sql=@sql+'drop procedure ['+name +'];' FROM sys.objects
WHERE type = 'p' AND  is_ms_shipped = 0
exec(@sql);

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

it seems that you should set your command as an String[],for example:

String[] command = new String[]{"rmiregistry","2020"};
Runtime.getRuntime().exec(command);

it just like the style of main(String[] args).

-z

string is null, that is, has zero length

String=''   # Zero-length ("null") string variable.

if [ -z "$String" ]
then
  echo "\$String is null."
else
  echo "\$String is NOT null."
fi     # $String is null.

Command:

foo >> output.txt 2>&1

appends to the output.txt file, without replacing the content.

The process handle will be signaled if it exits.

So the following will work (error handling removed for brevity):

BOOL IsProcessRunning(DWORD pid)
{
    HANDLE process = OpenProcess(SYNCHRONIZE, FALSE, pid);
    DWORD ret = WaitForSingleObject(process, 0);
    CloseHandle(process);
    return ret == WAIT_TIMEOUT;
}

Note that process ID's can be recycled - it's better to cache the handle that is returned from the CreateProcess call.

You can also use the threadpool API's (SetThreadpoolWait on Vista+, RegisterWaitForSingleObject on older platforms) to receive a callback when the process exits.

EDIT: I missed the "want to do something to the process" part of the original question. You can use this technique if it is ok to have potentially stale data for some small window or if you want to fail an operation without even attempting it. You will still have to handle the case where the action fails because the process has exited.

Actually without PDB files and symbolic information they have it would be impossible to create a successful crash report (memory dump files) and Microsoft would not have the complete picture what caused the problem.

And so having PDB improves crash reporting.

C# 6 adds a new feature just for this: extension Add methods. This has always been possible for VB.net but is now available in C#.

Now you don't have to add Add() methods to your classes directly, you can implement them as extension methods. When extending any enumerable type with an Add() method, you'll be able to use it in collection initializer expressions. So you don't have to derive from lists explicitly anymore (as mentioned in another answer), you can simply extend it.

public static class TupleListExtensions
{
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
            T1 item1, T2 item2)
    {
        list.Add(Tuple.Create(item1, item2));
    }

    public static void Add<T1, T2, T3>(this IList<Tuple<T1, T2, T3>> list,
            T1 item1, T2 item2, T3 item3)
    {
        list.Add(Tuple.Create(item1, item2, item3));
    }

    // and so on...
}

This will allow you to do this on any class that implements IList<>:

var numbers = new List<Tuple<int, string>>
{
    { 1, "one" },
    { 2, "two" },
    { 3, "three" },
    { 4, "four" },
    { 5, "five" },
};
var points = new ObservableCollection<Tuple<double, double, double>>
{
    { 0, 0, 0 },
    { 1, 2, 3 },
    { -4, -2, 42 },
};

Of course you're not restricted to extending collections of tuples, it can be for collections of any specific type you want the special syntax for.

public static class BigIntegerListExtensions
{
    public static void Add(this IList<BigInteger> list,
        params byte[] value)
    {
        list.Add(new BigInteger(value));
    }

    public static void Add(this IList<BigInteger> list,
        string value)
    {
        list.Add(BigInteger.Parse(value));
    }
}

var bigNumbers = new List<BigInteger>
{
    new BigInteger(1), // constructor BigInteger(int)

C# 7 will be adding in support for tuples built into the language, though they will be of a different type (System.ValueTuple instead). So to it would be good to add overloads for value tuples so you have the option to use them as well. Unfortunately, there are no implicit conversions defined between the two.

public static class ValueTupleListExtensions
{
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
        ValueTuple<T1, T2> item) => list.Add(item.ToTuple());
}

This way the list initialization will look even nicer.

var points = new List<Tuple<int, int, int>>
{
    (0, 0, 0),
    (1, 2, 3),
    (-1, 12, -73),
};

But instead of going through all this trouble, it might just be better to switch to using ValueTuple exclusively.

var points = new List<(int, int, int)>
{
    (0, 0, 0),
    (1, 2, 3),
    (-1, 12, -73),
};

Something like this:

class Class {
    // visibility will default to private unless you specify it
    struct Struct {
        //specify members here;
    };
};

Use WORKSPACE environment variable to change workspace directory.

If doing using Jenkinsfile, use following code :

dir("${env.WORKSPACE}/aQA"){
    sh "pwd"
}

To stop your loop you can use break with label. It will stop your loop for sure. Code is written in Java but aproach is the same for the all languages.

public void exitFromTheLoop() {
    boolean value = true;
            loop_label:for (int i = 0; i < 10; i++) {
              if(!value) { 
                 System.out.println("iteration: " + i);
              break loop_label;
        }
    }
}   

}

Here is another solution if the reason is that your video download is super slow and the video hasn't buffered:

if (videoElement.state.paused) { videoElement.play(); } else if (!isNaN(videoElement.state.duration)) { videoElement.pause(); }

If you want to use Graph API to get current user ID then just send a request to:

https://graph.facebook.com/me?access_token=...

If what you need is that the process should run forever no matter whether you are logged in or not, consider running the process as a daemon.

supervisord is a great out of the box solution that can be used to daemonize any process. It has another controlling utility supervisorctl that can be used to monitor processes that are being run by supervisor.

You don't have to write any extra code or modify existing scripts to make this work. Moreover, verbose documentation makes this process much simpler.

After scratching my head for hours around python-daemon, supervisor is the solution that worked for me in minutes.

Hope this helps someone trying to make python-daemon work

Considering the typical top-level class. Only public and no modifier access modifiers may be used at the top level so you'll either see public or you won't see any access modifier at all.

`static`` is used because you may not have a need to create an actual object at the top level (but sometimes you will want to so you may not always see/use static. There are other reasons why you wouldn't include static too but this is the typical one at the top level.)

void is used because usually you're not going to be returning a value from the top level (class). (sometimes you'll want to return a value other than NULL so void may not always be used either especially in the case when you have declared, initialized an object at the top level that you are assigning some value to).

Disclaimer: I'm a newbie myself so if this answer is wrong in any way please don't hang me. By day I'm a tech recruiter not a developer; coding is my hobby. Also, I'm always open to constructive criticism and love to learn so please feel free to point out any errors.

I think you just need to enable BrowserHistory on your router by intializing it like that : <Router history={new BrowserHistory}>.

Before that, you should require BrowserHistory from 'react-router/lib/BrowserHistory'

I hope that helps !

UPDATE : example in ES6

const BrowserHistory = require('react-router/lib/BrowserHistory').default;

const App = React.createClass({
    render: () => {
        return (
            <div><button onClick={BrowserHistory.goBack}>Go Back</button></div>
        );
    }
});

React.render((
    <Router history={BrowserHistory}>
        <Route path="/" component={App} />
    </Router>
), document.body);

Here is a method that does not require editing the code and works regardless of the number of characters.

More from Bill Phillip's article (go read it!) but i thought it was important to point out the following.

In ListView, there was some ambiguity about how to handle click events: Should the individual views handle those events, or should the ListView handle them through OnItemClickListener? In RecyclerView, though, the ViewHolder is in a clear position to act as a row-level controller object that handles those kinds of details.

We saw earlier that LayoutManager handled positioning views, and ItemAnimator handled animating them. ViewHolder is the last piece: it’s responsible for handling any events that occur on a specific item that RecyclerView displays.

It is a simple 3 Step Process :

1. Go to your private repo and click on settings
2. To the left of the screen click on Manage access
3. Then Click on Invite Collaborator

This, but also - the invited user needs to be logged in to Github before clicking the invitation link in their email or they'll get a 404 error.

Excerpt from PostgreSQL documentation:

Restricting and cascading deletes are the two most common options. [...] CASCADE specifies that when a referenced row is deleted, row(s) referencing it should be automatically deleted as well.

This means that if you delete a category – referenced by books – the referencing book will also be deleted by ON DELETE CASCADE.

Example:

CREATE SCHEMA shire;

CREATE TABLE shire.clans (
    id serial PRIMARY KEY,
    clan varchar
);

CREATE TABLE shire.hobbits (
    id serial PRIMARY KEY,
    hobbit varchar,
    clan_id integer REFERENCES shire.clans (id) ON DELETE CASCADE
);

DELETE FROM clans will CASCADE to hobbits by REFERENCES.

sauron@mordor> psql
sauron=# SELECT * FROM shire.clans;
 id |    clan    
----+------------
  1 | Baggins
  2 | Gamgi
(2 rows)

sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  1 | Bilbo    |       1
  2 | Frodo    |       1
  3 | Samwise  |       2
(3 rows)

sauron=# DELETE FROM shire.clans WHERE id = 1 RETURNING *;
 id |  clan   
----+---------
  1 | Baggins
(1 row)

DELETE 1
sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  3 | Samwise  |       2
(1 row)

If you really need the opposite (checked by the database), you will have to write a trigger!

Fixing that problem is very simple if you was using permalinks other than the default such as Day and name, Month and name, Numeric, Post name or Custom Structure, you only need to

Login to your admin area: Settings > Permalinks which should be : http://yoursite.com/wp-admin/options-permalink.php

Choose Default permalink setting, then save changes

Then you can return it again to your other previous permalink choice or keep it as default as yo wish

Note that this problem can happen when you move your site from a domain or location to another one.

There is a conflict between Visual Studio 2015 and Visual Studio Code for the git credentials. When i changed my credentials on VS 2015 VS Code let me push with the correct git ID.

None of the solutions offered here is a good solution. It may work for individual cases, but only if you're in control of the final display. Take my example: my work produces list of products they sell to retail. This is in CSV format and contain part-codes, some of them start with zero's, set by manufacturers (not under our control). Take away the leading zeroes and you may actually match another product. Retail customers want the list in CSV format because of back-end processing programs, that are also out of our control and different per customer, so we cannot change the format of the CSV files. No prefixed'=', nor added tabs. The data in the raw CSV files is correct; it's when customers open those files in Excel the problems start. And many customers are not really computer savvy. They can just about open and save an email attachment. We are thinking of providing the data in two slightly different formats: one as Excel Friendly (using the options suggested above by adding a TAB, the other one as the 'master'. But this may be wishful thinking as some customers will not understand why we need to do this. Meanwhile we continue to keep explaining why they sometimes see 'wrong' data in their spreadsheets. Until Microsoft makes a proper change I see no proper resolution to this, as long as one has no control over how end-users use the files.

Swift

yourImageView.contentMode = .center

You can use the following options to position your image:

• scaleToFill
• scaleAspectFit // contents scaled to fit with fixed aspect. remainder is transparent
• redraw // redraw on bounds change (calls -setNeedsDisplay)
• center // contents remain same size. positioned adjusted.
• top
• bottom
• left
• right
• topLeft
• topRight
• bottomLeft
• bottomRight

Use org.apache.commons.lang3.StringUtils

String emptyString = new String();    
result = StringUtils.defaultIfEmpty(emptyString, "default");
System.out.println(result);

String nullString = null;
result = StringUtils.defaultIfEmpty(nullString, "default");
System.out.println(result);

Both of the above options will print:

If you want the head command, one easy way to get it is to install Cygwin. Then you'll have all the UNIX tools at your disposal.

Sometimes, when a function name and a variable name to which the return of the function is stored are same, the error is shown. Just happened to me.

I had the same error in nodejs. But adding signatureVersion in s3 constructor helped me:

const s3 = new AWS.S3({
  apiVersion: '2006-03-01',
  signatureVersion: 'v4',
});

It seems to work fine in Google Chrome. Which browser are you using? Here the proof http://jsfiddle.net/CN8XL/

Anyhow you can also access to the input value parameter through the document.FormName.checkyear.value. You have to wrap in the input in a <form> tag like with the proper name attribute, like shown below:

<form name="FormName">
    <input type="hidden" name="checkyear" id="checkyear" value="">
</form>

Have you considered using the jQuery Library? Here are the docs for .val() function.

In the "Developer Tab" go to "Visual Basic" and create a Module. Copy paste the following. Remember changing the code, depending on what you want. Then run the module.

  Sub sbDelete_Rows_IF_Cell_Contains_String_Text_Value()
    Dim lRow As Long
    Dim iCntr As Long
    lRow = 390
    For iCntr = lRow To 1 Step -1
        If Cells(iCntr, 5).Value = "none" Then
            Rows(iCntr).Delete
        End If
    Next
    End Sub

lRow : Put the number of the rows that the current file has.

The number "5" in the "If" is for the fifth (E) column

http://en.wikipedia.org/wiki/Post/Redirect/Get

The most common way to implement this pattern in ASP.Net is to use Response.Redirect(Request.RawUrl)

Consider the differences between Redirect and Transfer. Transfer really isn't telling the browser to forward to a clear form, it's simply returning a cleared form. That may or may not be what you want.

Response.Redirect() does not a waste round trip. If you post to a script that clears the form by Server.Transfer() and reload you will be asked to repost by most browsers since the last action was a HTTP POST. This may cause your users to unintentionally repeat some action, eg. place a second order which will have to be voided later.

Precision and scale are often misunderstood. In numeric(3,2) you want 3 digits overall, but 2 to the right of the decimal. If you want 15 => 15.00 so the leading 1 causes the overflow (since if you want 2 digits to the right of the decimal, there is only room on the left for one more digit). With 4,2 there is no problem because all 4 digits fit.

Just to extend the answers a bit with what to do with the parsed object:

# JSON Parsing example
require "rubygems" # don't need this if you're Ruby v1.9.3 or higher
require "json"

string = '{"desc":{"someKey":"someValue","anotherKey":"value"},"main_item":{"stats":{"a":8,"b":12,"c":10}}}'
parsed = JSON.parse(string) # returns a hash

p parsed["desc"]["someKey"]
p parsed["main_item"]["stats"]["a"]

# Read JSON from a file, iterate over objects
file = open("shops.json")
json = file.read

parsed = JSON.parse(json)

parsed["shop"].each do |shop|
  p shop["id"]
end

try following statement

 Uri myuri = new Uri(System.Web.HttpContext.Current.Request.Url.AbsoluteUri);
 string pathQuery = myuri.PathAndQuery;
 string hostName = myuri.ToString().Replace(pathQuery , "");

Example1

 Input : http://localhost:4366/Default.aspx?id=notlogin
 Ouput : http://localhost:4366

Example2

 Input : http://support.domain.com/default.aspx?id=12345
 Output: support.domain.com

If you target android 5.0 and above. You could use:

Activity.startLockTask()

You could give the form and the link some ids and then subscribe for the onclick event of the link and submit the form:

<form id="myform" action="" method="POST">
    <a href="#" id="mylink"> submit </a>
</form>

and then:

window.onload = function() {
    document.getElementById('mylink').onclick = function() {
        document.getElementById('myform').submit();
        return false;
    };
};

I would recommend you using a submit button for submitting forms as it respects the markup semantics and it will work even for users with javascript disabled.

Also be careful with double-quotes -- on the Unix shell this expands variables. Some are obvious (like $foo and \t) but some are not (like !foo).

For safety, use single-quotes!

I think of return as a trick. As a general rule, the value of the last expression evaluated in a function becomes the function's value -- and this general pattern is found in many places. All of the following evaluate to 3:

local({
1
2
3
})

eval(expression({
1
2
3
}))

(function() {
1
2
3
})()

What return does is not really returning a value (this is done with or without it) but "breaking out" of the function in an irregular way. In that sense, it is the closest equivalent of GOTO statement in R (there are also break and next). I use return very rarely and never at the end of a function.

 if(a) {
   return(a)
 } else {
   return(b)
 }

... this can be rewritten as if(a) a else b which is much better readable and less curly-bracketish. No need for return at all here. My prototypical case of use of "return" would be something like ...

ugly <- function(species, x, y){
   if(length(species)>1) stop("First argument is too long.")
   if(species=="Mickey Mouse") return("You're kidding!")
   ### do some calculations 
   if(grepl("mouse", species)) {
      ## do some more calculations
      if(species=="Dormouse") return(paste0("You're sleeping until", x+y))
      ## do some more calculations
      return(paste0("You're a mouse and will be eating for ", x^y, " more minutes."))
      }
   ## some more ugly conditions
   # ...
   ### finally
   return("The end")
   }

Generally, the need for many return's suggests that the problem is either ugly or badly structured.

[EDIT]

return doesn't really need a function to work: you can use it to break out of a set of expressions to be evaluated.

getout <- TRUE 
# if getout==TRUE then the value of EXP, LOC, and FUN will be "OUTTA HERE"
# .... if getout==FALSE then it will be `3` for all these variables    

EXP <- eval(expression({
   1
   2
   if(getout) return("OUTTA HERE")
   3
   }))

LOC <- local({
   1
   2
   if(getout) return("OUTTA HERE")
   3
   })

FUN <- (function(){
   1
   2
   if(getout) return("OUTTA HERE")
   3
   })()

identical(EXP,LOC)
identical(EXP,FUN)

It's possible you want overloading or default parameters - define the same function with defaulted parameters:

void doStuff( int a, double termstator = 1.0, bool useFlag = true )
{
   // stuff
}

void doStuff( double std_termstator )
{
   // assume the user always wants '1' for the a param
   return doStuff( 1, std_termstator );
}

This will allow you to call the method with one of four different calls:

doStuff( 1 );
doStuff( 2, 2.5 );
doStuff( 1, 1.0, false );
doStuff( 6.72 );

... or you could be looking for the v_args calling conventions from C.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

I prefer option two because it clearly shows the list item as the possessor of that nested list. I would always lean towards semantically sound HTML.

<div [hidden]="myExpression">

myExpression may be set to true or false

In my opinion the bare minimum implementation has two requirements. A state that keeps track of whether the modal is open or not, and a portal to render the modal outside of the standard react tree.

The ModalContainer component below implements those requirements along with corresponding render functions for the modal and the trigger, which is responsible for executing the callback to open the modal.

import React from 'react';
import PropTypes from 'prop-types';
import Portal from 'react-portal';

class ModalContainer extends React.Component {
  state = {
    isOpen: false,
  };

  openModal = () => {
    this.setState(() => ({ isOpen: true }));
  }

  closeModal = () => {
    this.setState(() => ({ isOpen: false }));
  }

  renderModal() {
    return (
      this.props.renderModal({
        isOpen: this.state.isOpen,
        closeModal: this.closeModal,
      })
    );
  }

  renderTrigger() {
     return (
       this.props.renderTrigger({
         openModal: this.openModal
       })
     )
  }

  render() {
    return (
      <React.Fragment>
        <Portal>
          {this.renderModal()}
        </Portal>
        {this.renderTrigger()}
      </React.Fragment>
    );
  }
}

ModalContainer.propTypes = {
  renderModal: PropTypes.func.isRequired,
  renderTrigger: PropTypes.func.isRequired,
};

export default ModalContainer;

And here's a simple use case...

import React from 'react';
import Modal from 'react-modal';
import Fade from 'components/Animations/Fade';
import ModalContainer from 'components/ModalContainer';

const SimpleModal = ({ isOpen, closeModal }) => (
  <Fade visible={isOpen}> // example use case with animation components
    <Modal>
      <Button onClick={closeModal}>
        close modal
      </Button>
    </Modal>
  </Fade>
);

const SimpleModalButton = ({ openModal }) => (
  <button onClick={openModal}>
    open modal
  </button>
);

const SimpleButtonWithModal = () => (
   <ModalContainer
     renderModal={props => <SimpleModal {...props} />}
     renderTrigger={props => <SimpleModalButton {...props} />}
   />
);

export default SimpleButtonWithModal;

I use render functions, because I want to isolate state management and boilerplate logic from the implementation of the rendered modal and trigger component. This allows the rendered components to be whatever you want them to be. In your case, I suppose the modal component could be a connected component that receives a callback function that dispatches an asynchronous action.

If you need to send dynamic props to the modal component from the trigger component, which hopefully doesn't happen too often, I recommend wrapping the ModalContainer with a container component that manages the dynamic props in its own state and enhance the original render methods like so.

import React from 'react'
import partialRight from 'lodash/partialRight';
import ModalContainer from 'components/ModalContainer';

class ErrorModalContainer extends React.Component {
  state = { message: '' }

  onError = (message, callback) => {
    this.setState(
      () => ({ message }),
      () => callback && callback()
    );
  }

  renderModal = (props) => (
    this.props.renderModal({
       ...props,
       message: this.state.message,
    })
  )

  renderTrigger = (props) => (
    this.props.renderTrigger({
      openModal: partialRight(this.onError, props.openModal)
    })
  )

  render() {
    return (
      <ModalContainer
        renderModal={this.renderModal}
        renderTrigger={this.renderTrigger}
      />
    )
  }
}

ErrorModalContainer.propTypes = (
  ModalContainer.propTypes
);

export default ErrorModalContainer;
