The solution of Quango in is working but I prefer to resolve it by adding this code in my Web.config like new projects :

<system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs"
        type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=3.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
        warningLevel="4" compilerOptions="/langversion:default /nowarn:1659;1699;1701"/>
      <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb"
        type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=3.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
        warningLevel="4" compilerOptions="/langversion:default /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+"/>
    </compilers>
  </system.codedom>

Repairing Visual Studio 2015 seems to have resolved this issue for me. See this issue for NuGet in GitHub.

If you're looking for some ESP alternatives, you should have a look at Mailjet for Microsoft Azure too! As a global email service and infrastructure provider, they enable you to send, deliver and track transactional and marketing emails via their APIs, SMTP Relay or UI all from one single platform, thought both for developers and emails owners.

Disclaimer: I’m working at Mailjet as a Developer Evangelist.

Like this:

{% if age > 18 %}
    {% with patient as p %}
    <my html here>
    {% endwith %}
{% else %}
    {% with patient.parent as p %}
    <my html here>
    {% endwith %}
{% endif %}

If the html is too big and you don't want to repeat it, then the logic would better be placed in the view. You set this variable and pass it to the template's context:

p = (age > 18 && patient) or patient.parent

and then just use {{ p }} in the template.

Typically you would accomplish this using an ajax request that looks like

var xhr = new XMLHttpRequest();
xhr.open("GET", "pythoncode.py?text=" + text, true);
xhr.responseType = "JSON";
xhr.onload = function(e) {
  var arrOfStrings = JSON.parse(xhr.response);
}
xhr.send();

I know this is a little late, however for anyone interested, I've created a custom component that is basically a toggle image button, the drawable can have states as well as the background

In short, git is trying to access a repo it considers on another filesystem and to tell it explicitly that you're okay with this, you must set the environment variable GIT_DISCOVERY_ACROSS_FILESYSTEM=1

I'm working in a CI/CD environment and using a dockerized git so I have to set it in that environment docker run -e GIT_DISCOVERY_ACROSS_FILESYSTEM=1 -v $(pwd):/git --rm alpine/git rev-parse --short HEAD\'

If you're curious: Above mounts $(pwd) into the git docker container and passes "rev-parse --short HEAD" to the git command in the container, which it then runs against that mounted volums.

Try setting this before you print:

setvbuf (stdout, NULL, _IONBF, 0);

You can use the xmljson library to convert using different XML JSON conventions.

For example, this XML:

<p id="1">text</p>

translates via the BadgerFish convention into this:

{
  'p': {
    '@id': 1,
    '$': 'text'
  }
}

and via the GData convention into this (attributes are not supported):

{
  'p': {
    '$t': 'text'
  }
}

... and via the Parker convention into this (attributes are not supported):

{
  'p': 'text'
}

It's possible to convert from XML to JSON and from JSON to XML using the same conventions:

>>> import json, xmljson
>>> from lxml.etree import fromstring, tostring
>>> xml = fromstring('<p id="1">text</p>')
>>> json.dumps(xmljson.badgerfish.data(xml))
'{"p": {"@id": 1, "$": "text"}}'
>>> xmljson.parker.etree({'ul': {'li': [1, 2]}})
# Creates [<ul><li>1</li><li>2</li></ul>]

Disclosure: I wrote this library. Hope it helps future searchers.

Maybe this resource is useful helping decide between both. It also discusses several other NoSQL databases, and offers a short list of characteristics, along with a "what I would use it for" explanation for each of them.

Just import library https://github.com/jasonpolites/gesture-imageview.

into your project and add the following in your layout file:

<LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:gesture-image="http://schemas.polites.com/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent">

<com.polites.android.GestureImageView
   android:id="@+id/image"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:src="@drawable/image"
   gesture-image:min-scale="0.1"
   gesture-image:max-scale="10.0"
   gesture-image:strict="false"/>`

To calculate the sum of a column in a DataTable use the DataTable.Compute method.

Example of usage from the linked MSDN article:

DataTable table = dataSet.Tables["YourTableName"];

// Declare an object variable.
object sumObject;
sumObject = table.Compute("Sum(Amount)", string.Empty);

Display the result in your Total Amount Label like so:

lblTotalAmount.Text = sumObject.ToString();

I think I see your problem, you need to use the @ syntax to define parameters you will pass in this way, also I'm not sure what loginID or password are doing you don't seem to define them anywhere and they are not being used as URL parameters so are they being sent as query parameters?

This is what I can suggest based on what I see so far:

.factory('MagComments', function ($resource) {
    return $resource('http://localhost/dooleystand/ci/api/magCommenct/:id', {
      loginID : organEntity,
      password : organCommpassword,
      id : '@magId'
    });
  })

The @magId string will tell the resource to replace :id with the property magId on the object you pass it as parameters.

I'd suggest reading over the documentation here (I know it's a bit opaque) very carefully and looking at the examples towards the end, this should help a lot.

You can use microtime and calculate the difference:

$time_pre = microtime(true);
exec(...);
$time_post = microtime(true);
$exec_time = $time_post - $time_pre;

Here's the PHP docs for microtime: http://php.net/manual/en/function.microtime.php

The following sequence of commands does remove every name from the current module:

>>> import sys
>>> sys.modules[__name__].__dict__.clear()

I doubt you actually DO want to do this, because "every name" includes all built-ins, so there's not much you can do after such a total wipe-out. Remember, in Python there is really no such thing as a "variable" -- there are objects, of many kinds (including modules, functions, class, numbers, strings, ...), and there are names, bound to objects; what the sequence does is remove every name from a module (the corresponding objects go away if and only if every reference to them has just been removed).

Maybe you want to be more selective, but it's hard to guess exactly what you mean unless you want to be more specific. But, just to give an example:

>>> import sys
>>> this = sys.modules[__name__]
>>> for n in dir():
...   if n[0]!='_': delattr(this, n)
... 
>>>

This sequence leaves alone names that are private or magical, including the __builtins__ special name which houses all built-in names. So, built-ins still work -- for example:

>>> dir()
['__builtins__', '__doc__', '__name__', '__package__', 'n']
>>> 

As you see, name n (the control variable in that for) also happens to stick around (as it's re-bound in the for clause every time through), so it might be better to name that control variable _, for example, to clearly show "it's special" (plus, in the interactive interpreter, name _ is re-bound anyway after every complete expression entered at the prompt, to the value of that expression, so it won't stick around for long;-).

Anyway, once you have determined exactly what it is you want to do, it's not hard to define a function for the purpose and put it in your start-up file (if you want it only in interactive sessions) or site-customize file (if you want it in every script).

You can use the following. They all wrap the window object into a jQuery object.

Load:

$(window).load(function () {
    topInViewport($("#mydivname"))
});

Resize:

$(window).resize(function () {
   topInViewport($("#mydivname"))
});

Scroll

$(window).scroll(function () {
    topInViewport($("#mydivname"))
});

Or bind to them all using on:

$(window).on("load resize scroll",function(e){
    topInViewport($("#mydivname"))
});

If you want to due this in component.ts

HTML:

<button class="class1 class2" (click)="clicked($event)">Click me</button>

Component:

clicked(event) {
  event.target.classList.add('class3'); // To ADD
  event.target.classList.remove('class1'); // To Remove
  event.target.classList.contains('class2'); // To check
  event.target.classList.toggle('class4'); // To toggle
}

In Linux command Prompt, I would first stop all postgresql processes that are running by tying this command sudo /etc/init.d/postgresql restart

type the command bg to check if other postgresql processes are still running

then followed by dropdb dbname to drop the database

bg
dropdb dbname

This works for me on linux command prompt

javax.servlet is a package that's part of Java EE (Java Enterprise Edition). You've got the JDK for Java SE (Java Standard Edition).

You could use the Java EE SDK for example.

Alternatively simple servlet containers such as Apache Tomcat also come with this API (look for servlet-api.jar).

Most of these solutions depend on there being an odd number of items so that you can take the middle item and center it. What if you have an even number of items that you still want to be evenly distributed? Here's a more general solution. This category will evenly distribute any number of items along either the vertical or horizontal axis.

Example usage to vertically distribute 4 labels within their superview:

[self.view addConstraints:
     [NSLayoutConstraint constraintsForEvenDistributionOfItems:@[label1, label2, label3, label4]
                                        relativeToCenterOfItem:self.view
                                                    vertically:YES]];

Assuming you do as David Zaslavsky suggests, so that the first argument simply is the program to run (no option-parsing required), you're dealing with the question of how to pass arguments 2 and on to your external program. Here's a convenient way:

#!/bin/bash
ext_program="$1"
shift
"$ext_program" "$@"

The shift will remove the first argument, renaming the rest ($2 becomes $1, and so on).$@` refers to the arguments, as an array of words (it must be quoted!).

If you must have your --file syntax (for example, if there's a default program to run, so the user doesn't necessarily have to supply one), just replace ext_program="$1" with whatever parsing of $1 you need to do, perhaps using getopt or getopts.

If you want to roll your own, for just the one specific case, you could do something like this:

if [ "$#" -gt 0 -a "${1:0:6}" == "--file" ]; then
    ext_program="${1:7}"
else
    ext_program="default program"
fi

Cong Ma does a good job of explaining what __getitem__ is used for - but I want to give you an example which might be useful. Imagine a class which models a building. Within the data for the building it includes a number of attributes, including descriptions of the companies that occupy each floor :

Without using __getitem__ we would have a class like this :

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def occupy(self, floor_number, data):
          self._floors[floor_number] = data
     def get_floor_data(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1.occupy(0, 'Reception')
building1.occupy(1, 'ABC Corp')
building1.occupy(2, 'DEF Inc')
print( building1.get_floor_data(2) )

We could however use __getitem__ (and its counterpart __setitem__) to make the usage of the Building class 'nicer'.

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def __setitem__(self, floor_number, data):
          self._floors[floor_number] = data
     def __getitem__(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1[0] = 'Reception'
building1[1] = 'ABC Corp'
building1[2] = 'DEF Inc'
print( building1[2] )

Whether you use __setitem__ like this really depends on how you plan to abstract your data - in this case we have decided to treat a building as a container of floors (and you could also implement an iterator for the Building, and maybe even the ability to slice - i.e. get more than one floor's data at a time - it depends on what you need.

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

Is there a way to set the session timeout programatically

There are basically three ways to set the session timeout value:

• by using the session-timeout in the standard web.xml file ~or~
• in the absence of this element, by getting the server's default session-timeout value (and thus configuring it at the server level) ~or~
• programmatically by using the HttpSession. setMaxInactiveInterval(int seconds) method in your Servlet or JSP.

But note that the later option sets the timeout value for the current session, this is not a global setting.

LAZY: It fetches the child entities lazily i.e at the time of fetching parent entity it just fetches proxy(created by cglib or any other utility) of the child entities and when you access any property of child entity then it is actually fetched by hibernate.

EAGER: it fetches the child entities along with parent.

For better understanding go to Jboss documentation or you can use hibernate.show_sql=true for your app and check the queries issued by the hibernate.

Automatic copying to the clipboard may be dangerous, and therefore most browsers (except Internet Explorer) make it very difficult. Personally, I use the following simple trick:

function copyToClipboard(text) {
  window.prompt("Copy to clipboard: Ctrl+C, Enter", text);
}

The user is presented with the prompt box, where the text to be copied is already selected. Now it's enough to press Ctrl + C and Enter (to close the box) -- and voila!

Now the clipboard copy operation is safe, because the user does it manually (but in a pretty straightforward way). Of course, it works in all browsers.

<button id="demo" onclick="copyToClipboard(document.getElementById('demo').innerHTML)">This is what I want to copy</button>

<script>
  function copyToClipboard(text) {
    window.prompt("Copy to clipboard: Ctrl+C, Enter", text);
  }
</script>

Python or Python3 with MySQL, you will need these. These libraries use MySQL's connector for C and Python (you need the C libraries installed as well), which overcome some of the limitations of the mysqldb libraries.

   sudo apt-get install libmysqlclient-dev
   sudo apt-get install python-mysql.connector
   sudo apt-get install python3-mysql.connector

It was pretty odd the trick that worked. The thing is when I have previously read the content of the file, I used BufferedReader. After reading, I closed the buffer.

Meanwhile I switched and now I'm reading the content using FileInputStream. Also after finishing reading I close the stream. And now it's working.

The problem is I don't have the explanation for this.

I don't know BufferedReader and FileOutputStream to be incompatible.

MOV can do same thing as LEA [label], but MOV instruction contain the effective address inside the instruction itself as an immediate constant (calculated in advance by the assembler). LEA uses PC-relative to calculate the effective address during the execution of the instruction.

If you don't like "verbosity" you can always wrap your code in a short method:

private void msgbox(String s){
   JOptionPane.showMessageDialog(null, s);
}

and the usage:

msgbox("don't touch that!");

Here is a complete example that has been tested with Python 2.7.5 on CentOS 7.

#!/usr/bin/python

import sys, socket

def main(args):
    ip = args[1]
    port = int(args[2])
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    file = 'sample.csv'

    fp = open(file, 'r')
    for line in fp:
        sock.sendto(line.encode('utf-8'), (ip, port))
    fp.close()

main(sys.argv)

The program reads a file, sample.csv from the current directory and sends each line in a separate UDP packet. If the program it were saved in a file named send-udp then one could run it by doing something like:

$ python send-udp 192.168.1.2 30088

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

I think it's a matter of preference. I personally use:

if($something){
       $execute_something;
}

I'd suggest you use the TimeSpan class for this.

public static void Main(string[] args)
{
    TimeSpan t = TimeSpan.FromSeconds(80);
    Console.WriteLine(t.ToString());

    t = TimeSpan.FromSeconds(868693412);
    Console.WriteLine(t.ToString());
}

Outputs:

00:01:20
10054.07:43:32

to answer to your second question - performance IS affected - if you are using those selectors with a single (no nested) ul:

<ul>
    <li>jjj</li>
    <li>jjj</li>    
    <li>jjj</li>
</ul>

the child selector ul > li is more performant than ul li because it is more specific. the browser traverse the dom "right to left", so when it finds a li it then looks for a any ul as a parent in the case of a child selector, while it has to traverse the whole dom tree to find any ul ancestors in case of the descendant selector

Reorient your mental model of the functionality of "CASCADE" by thinking of adding a FK to an already existing cascade (i.e. a waterfall). The source of this waterfall is a primary key (PK). Deletes flow down.

So if you define a FK's on_delete as "CASCADE," you're adding this FK's record to a cascade of deletes originating from the PK. The FK's record may participate in this cascade or not ("SET_NULL"). In fact, a record with a FK may even prevent the flow of the deletes! Build a dam with "PROTECT."

The hide selector was incorrect. I hid the blocks at page load and showed the selected value. I also changed the car div id's to make it easier to append the radio button value and create the proper id selector.

<div id="myRadioGroup">
  2 Cars<input type="radio" name="cars" checked="checked" value="2"  />
  3 Cars<input type="radio" name="cars" value="3" />
  <div id="car-2">
  2 Cars
  </div>
  <div id="car-3">
  3 Cars
  </div>
</div>

<script type="text/javascript">
$(document).ready(function(){ 
  $("div div").hide();
  $("#car-2").show();
  $("input[name$='cars']").click(function() {
      var test = $(this).val();
      $("div div").hide();
      $("#car-"+test).show();
  }); 
});
</script>

Basic method for beginners like me.

public void loadDataToJtable(ArrayList<String> liste){
        
    rows = table.getRowCount();

    cols = table.getColumnCount();

    for (int i = 0; i < rows ; i++) {

            for ( int k  = 0; k < cols ; k++) {
            
            for (int h = 0; h < list1.size(); h++) {
                
                String b =  list1.get(h);
                b = table.getValueAt(i, k).toString();
                
            }
        }
    }
}

In curl request add time out 0 so its infinite time set like CURLOPT_TIMEOUT set 0

        System.out.println("Size of List: "+myElements.size());
        for(WebElement e : myElements) 
        {        
            System.out.print("Text within the Anchor tab"+e.getText()+"\t");

//NOTE: "//a" will give you all the anchors there on after the point your XPATH has reached.

TextField widget has a property decoration which has a sub property border: InputBorder.none.This property would Remove TextField Text Input Bottom Underline in Flutter app. So you can set the border property of the decoration of the TextField to InputBorder.none, see here for an example:

border: InputBorder.none : Hide bottom underline from Text Input widget.

 Container(
        width: 280,
        padding: EdgeInsets.all(8.0),
        child : TextField(
                autocorrect: true,
                decoration: InputDecoration(
                border: InputBorder.none,
                hintText: 'Enter Some Text Here')
            )
    )

This works for Python 2 & 3:

from itertools import islice

with open('/tmp/filename.txt') as inf:
    for line in islice(inf, N, N+M):
        print(line)

Ensure you run Visual Studio as an administrator.

Simply replace

print $image;

with

 echo '<img src=".$image." >';

Late answer but felt to add some points here.

Session storage will be available for specific tab where as we can use Local storage through out the browser. Both are default to same origin and we can also store values manually with key, value pairs (value must be string).

Once tab (session) of the browser is closed then Session storage will be cleared on that tab, where as in case of Local storage we need to clear it explicitly. Maximum storage limit respectively 5MB and 10MB.

We can save and retrieve the data like below,

To Save:

sessionStorage.setItem('id', noOfClicks);   // localStorage.setItem('id', noOfClicks);

sessionStorage.setItem('userDetails', JSON.stringify(userDetails));   // if it's object

To Get:

sessionStorage.getItem('id');    // localStorage.getItem('id');

User user = JSON.parse(sessionStorage.getItem("userDetails")) as User;  // if it's object

To Modify:

sessionStorage.removeItem('id');    // localStorage.removeItem('id');

sessionStorage.clear();   // localStorage.clear();

P.S: getItem() also return back the data as string and we need convert it into JSON format to access if it's object.

Use another flex container to fix the min-height issue in IE10 and IE11:

HTML

<div class="ie-fixMinHeight">
    <div id="page">
        <div id="header"></div>
        <div id="content"></div>
        <div id="footer"></div>
    </div>
</div>

CSS

.ie-fixMinHeight {
    display:flex;
}

#page {
    min-height:100vh;
    width:100%;
    display:flex;
    flex-direction:column;
}

#content {
    flex-grow:1;
}

See a working demo.

• Don't use flexbox layout directly on body because it screws up elements inserted via jQuery plugins (autocomplete, popup, etc.).
• Don't use height:100% or height:100vh on your container because the footer will stick at the bottom of window and won't adapt to long content.
• Use flex-grow:1 rather than flex:1 cause IE10 and IE11 default values for flex are 0 0 auto and not 0 1 auto.

You do not need to use moment-timezone for this. The main moment.js library has full functionality for working with UTC and the local time zone.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).local();

From there you can use any of the functions you might expect:

var s = localDate.format("YYYY-MM-DD HH:mm:ss");
var d = localDate.toDate();
// etc...

Note that by passing testDateUtc, which is a moment object, back into the moment() constructor, it creates a clone. Otherwise, when you called .local(), it would also change the testDateUtc value, instead of just the localDate value. Moments are mutable.

Also note that if your original input contains a time zone offset such as +00:00 or Z, then you can just parse it directly with moment. You don't need to use .utc or .local. For example:

var localDate = moment("2015-01-30T10:00:00Z");

Before User Shift + = or Shift - , you have to first set the key map as mentioned below

int g[] = {9,8};

This declares an object of type int[2], and initializes its elements to {9,8}

int (*j) = g;

This declares an object of type int *, and initializes it with a pointer to the first element of g.

The fact that the second declaration initializes j with something other than g is pretty strange. C and C++ just have these weird rules about arrays, and this is one of them. Here the expression g is implicitly converted from an lvalue referring to the object g into an rvalue of type int* that points at the first element of g.

This conversion happens in several places. In fact it occurs when you do g[0]. The array index operator doesn't actually work on arrays, only on pointers. So the statement int x = j[0]; works because g[0] happens to do that same implicit conversion that was done when j was initialized.

A pointer to an array is declared like this

int (*k)[2];

and you're exactly right about how this would be used

int x = (*k)[0];

(note how "declaration follows use", i.e. the syntax for declaring a variable of a type mimics the syntax for using a variable of that type.)

However one doesn't typically use a pointer to an array. The whole purpose of the special rules around arrays is so that you can use a pointer to an array element as though it were an array. So idiomatic C generally doesn't care that arrays and pointers aren't the same thing, and the rules prevent you from doing much of anything useful directly with arrays. (for example you can't copy an array like: int g[2] = {1,2}; int h[2]; h = g;)

Examples:

void foo(int c[10]); // looks like we're taking an array by value.
// Wrong, the parameter type is 'adjusted' to be int*

int bar[3] = {1,2};
foo(bar); // compile error due to wrong types (int[3] vs. int[10])?
// No, compiles fine but you'll probably get undefined behavior at runtime

// if you want type checking, you can pass arrays by reference (or just use std::array):
void foo2(int (&c)[10]); // paramater type isn't 'adjusted'
foo2(bar); // compiler error, cannot convert int[3] to int (&)[10]

int baz()[10]; // returning an array by value?
// No, return types are prohibited from being an array.

int g[2] = {1,2};
int h[2] = g; // initializing the array? No, initializing an array requires {} syntax
h = g; // copying an array? No, assigning to arrays is prohibited

Because arrays are so inconsistent with the other types in C and C++ you should just avoid them. C++ has std::array that is much more consistent and you should use it when you need statically sized arrays. If you need dynamically sized arrays your first option is std::vector.

new ES6:

'import' should be used with 'export' key words to share variables/arrays/objects between js files:

export default myObject;

//....in another file

import myObject from './otherFile.js';

old skool:

'require' should be used with 'module.exports'

 module.exports = myObject;

//....in another file

var myObject = require('./otherFile.js');

NULL is not a built-in constant in the C or C++ languages. In fact, in C++ it's more or less obsolete, just use a plain literal 0 instead, the compiler will do the right thing depending on the context.

In newer C++ (C++11 and higher), use nullptr (as pointed out in a comment, thanks).

Otherwise, add

#include <stddef.h>

to get the NULL definition.

The MSDN is a good reference for these type of questions regarding syntax and usage. This is from the Transact SQL Reference - CASE page.

Another good site you may want to check out if you're using SQL Server is SQL Server Central. This has a large variety of resources available for whatever area of SQL Server you would like to learn.

// example of goto in javascript:

var i, j;
loop_1:
    for (i = 0; i < 3; i++) { //The first for statement is labeled "loop_1"
        loop_2:
            for (j = 0; j < 3; j++) { //The second for statement is labeled "loop_2"
                if (i === 1 && j === 1) {
                    continue loop_1;

Funny, I was doing precisely this yesterday. You just need this in your css file

.ablock table td {
     padding:5px;
}

then wrap the table in a suitable div

<div class="ablock ">
<table>
  <tr>
    <td>

If you have some form data for example sent to home#action, now you want to redirect them to house#act while keeping the parameters, you can do this

redirect_to act_house_path(request.parameters)

On newer versions of Symfony2 (using a parameters.yml instead of parameters.ini), you can store objects or arrays instead of key-value pairs, so you can manage your globals this way:

config.yml (edited only once):

# app/config/config.yml
twig:
  globals:
    project: %project%

parameters.yml:

# app/config/parameters.yml
project:
  name:       myproject.com
  version:    1.1.42

And then in a twig file, you can use {{ project.version }} or {{ project.name }}.

Note: I personally dislike adding things to app, just because that's the Symfony's variable and I don't know what will be stored there in the future.

There is the way to safely removed system-image

Yes, using DateFormat.getDateInstance(int style, Locale aLocale) This displays the current date in a locale-specific way.

So, for example:

DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, yourLocale);
String formattedDate = df.format(yourDate);

See the docs for the exact meaning of the style parameter (SHORT, MEDIUM, etc)

#!/bin/bash
duration=120    # seconds
instances=4     # cpus
endtime=$(($(date +%s) + $duration))
for ((i=0; i<instances; i++))
do
    while (($(date +%s) < $endtime)); do :; done &
done

A variable is final or effectively final when it's initialized once and it's never mutated in its owner class. And we can't initialize it in loops or inner classes.

Final:

final int number;
number = 23;

Effectively Final:

int number;
number = 34;

Note: Final and Effective Final are similar(Their value don't change after assignment) but just that effective Final variables are not declared with Keyword final.

you can pickle your dict and save as string.

import pickle
import redis

r = redis.StrictRedis('localhost')
mydict = {1:2,2:3,3:4}
p_mydict = pickle.dumps(mydict)
r.set('mydict',p_mydict)

read_dict = r.get('mydict')
yourdict = pickle.loads(read_dict)

In case you want to use bootstrap radio to check one of them depends on the result of your checked var in the .ts file.

component.html

<div class="btn-group btn-group-toggle" data-toggle="buttons" >
   <label [ngClass]="checked ? 'active' : ''" class="btn btn-outline-secondary">
     <input name="radio" id="radio1" value="option1" type="radio"> TRUE
   </label>
   <label [ngClass]="!checked ? 'active' : ''" class="btn btn-outline-secondary">
     <input name="radio" id="radio2" value="option2" type="radio"> FALSE
   </label>
</div>

component.ts file

@Component({
  selector: '',
  templateUrl: './.component.html',
  styleUrls: ['./.component.css']
})
export class radioComponent implements OnInit {
  checked = true;
}

Move file:

File from = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/kaic1/imagem.jpg");
File to = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/kaic2/imagem.jpg");
from.renameTo(to);

use Latin1_General_CS as your collation in your sql db

Pay attention to the zero problem with some of the answers. For example, the timestamp 1439329773 would be mistakenly converted to 12/08/2015 0:49.

I would suggest on using the following to overcome this issue:

var timestamp = 1439329773; // replace your timestamp
var date = new Date(timestamp * 1000);
var formattedDate = ('0' + date.getDate()).slice(-2) + '/' + ('0' + (date.getMonth() + 1)).slice(-2) + '/' + date.getFullYear() + ' ' + ('0' + date.getHours()).slice(-2) + ':' + ('0' + date.getMinutes()).slice(-2);
console.log(formattedDate);

Now results in:

12/08/2015 00:49

You can still use it (mysqli is just another way of communicating with the server, the SQL language itself is expanded, not changed). Prepared statements are safer, though - since you don't need to go through the trouble of properly escaping your values each time. You can leave them as they were, if you want to but the risk of sql piggybacking is reduced if you switch.

WITH CHECK is indeed the default behaviour however it is good practice to include within your coding.

The alternative behaviour is of course to use WITH NOCHECK, so it is good to explicitly define your intentions. This is often used when you are playing with/modifying/switching inline partitions.

I had the same problem for a while and despite doing mvn -U clean install the problem was not getting solved!

I finally solved the problem by deleting the whole .m2 folder and then restarted my IDE and the problem was gone!

So sometimes the problem would rise because of some incompatibilities or problems in your local maven repository.

In the following link you can find useful info about recording with AVAudioRecording. In this link in the first part "USing Audio" there is an anchor named “Recording with the AVAudioRecorder Class.” that leads you to the example.

Keystore only has one password. You can change it using keytool:

keytool -storepasswd -keystore my.keystore

To change the key's password:

keytool -keypasswd  -alias <key_name> -keystore my.keystore

Using direct conditions (like ==, !=, !condition) will have a slight performance improvement over the .equals(condition) as in one case you are calling the method from an object whereas direct comparisons are performed directly.

I see good answers have already been given, but I thought it might be nice to just give a way to perform mean filtering in MATLAB using no special functions or toolboxes. This is also very good for understanding exactly how the process works as you are required to explicitly set the convolution kernel. The mean filter kernel is fortunately very easy:

I = imread(...)
kernel = ones(3, 3) / 9; % 3x3 mean kernel
J = conv2(I, kernel, 'same'); % Convolve keeping size of I

Note that for colour images you would have to apply this to each of the channels in the image.

OCR which stands for Optical Character Recognition is a computer vision technique used to identify the different types of handwritten digits that are used in common mathematics. To perform OCR in OpenCV we will use the KNN algorithm which detects the nearest k neighbors of a particular data point and then classifies that data point based on the class type detected for n neighbors.

Data Used

This data contains 5000 handwritten digits where there are 500 digits for every type of digit. Each digit is of 20×20 pixel dimensions. We will split the data such that 250 digits are for training and 250 digits are for testing for every class.

Below is the implementation.

Output

91.64

Well, I decided to workout myself on my question to solve the above problem. What I wanted is to implement a simple OCR using KNearest or SVM features in OpenCV. And below is what I did and how. (it is just for learning how to use KNearest for simple OCR purposes).

1) My first question was about letter_recognition.data file that comes with OpenCV samples. I wanted to know what is inside that file.

It contains a letter, along with 16 features of that letter.

And this SOF helped me to find it. These 16 features are explained in the paper Letter Recognition Using Holland-Style Adaptive Classifiers. (Although I didn't understand some of the features at the end)

2) Since I knew, without understanding all those features, it is difficult to do that method. I tried some other papers, but all were a little difficult for a beginner.

So I just decided to take all the pixel values as my features. (I was not worried about accuracy or performance, I just wanted it to work, at least with the least accuracy)

I took the below image for my training data:

(I know the amount of training data is less. But, since all letters are of the same font and size, I decided to try on this).

To prepare the data for training, I made a small code in OpenCV. It does the following things:

1. It loads the image.
2. Selects the digits (obviously by contour finding and applying constraints on area and height of letters to avoid false detections).
3. Draws the bounding rectangle around one letter and wait for key press manually. This time we press the digit key ourselves corresponding to the letter in the box.
4. Once the corresponding digit key is pressed, it resizes this box to 10x10 and saves all 100 pixel values in an array (here, samples) and corresponding manually entered digit in another array(here, responses).
5. Then save both the arrays in separate .txt files.

At the end of the manual classification of digits, all the digits in the training data (train.png) are labeled manually by ourselves, image will look like below:

Below is the code I used for the above purpose (of course, not so clean):

import sys

import numpy as np
import cv2

im = cv2.imread('pitrain.png')
im3 = im.copy()

gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray,(5,5),0)
thresh = cv2.adaptiveThreshold(blur,255,1,1,11,2)

#################      Now finding Contours         ###################

contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)

samples =  np.empty((0,100))
responses = []
keys = [i for i in range(48,58)]

for cnt in contours:
    if cv2.contourArea(cnt)>50:
        [x,y,w,h] = cv2.boundingRect(cnt)
        
        if  h>28:
            cv2.rectangle(im,(x,y),(x+w,y+h),(0,0,255),2)
            roi = thresh[y:y+h,x:x+w]
            roismall = cv2.resize(roi,(10,10))
            cv2.imshow('norm',im)
            key = cv2.waitKey(0)

            if key == 27:  # (escape to quit)
                sys.exit()
            elif key in keys:
                responses.append(int(chr(key)))
                sample = roismall.reshape((1,100))
                samples = np.append(samples,sample,0)

responses = np.array(responses,np.float32)
responses = responses.reshape((responses.size,1))
print "training complete"

np.savetxt('generalsamples.data',samples)
np.savetxt('generalresponses.data',responses)

Now we enter in to training and testing part.

For the testing part, I used the below image, which has the same type of letters I used for the training phase.

For training we do as follows:

1. Load the .txt files we already saved earlier
2. create an instance of the classifier we are using (it is KNearest in this case)
3. Then we use KNearest.train function to train the data

For testing purposes, we do as follows:

1. We load the image used for testing
2. process the image as earlier and extract each digit using contour methods
3. Draw a bounding box for it, then resize it to 10x10, and store its pixel values in an array as done earlier.
4. Then we use KNearest.find_nearest() function to find the nearest item to the one we gave. ( If lucky, it recognizes the correct digit.)

I included last two steps (training and testing) in single code below:

import cv2
import numpy as np

#######   training part    ############### 
samples = np.loadtxt('generalsamples.data',np.float32)
responses = np.loadtxt('generalresponses.data',np.float32)
responses = responses.reshape((responses.size,1))

model = cv2.KNearest()
model.train(samples,responses)

############################# testing part  #########################

im = cv2.imread('pi.png')
out = np.zeros(im.shape,np.uint8)
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
thresh = cv2.adaptiveThreshold(gray,255,1,1,11,2)

contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)

for cnt in contours:
    if cv2.contourArea(cnt)>50:
        [x,y,w,h] = cv2.boundingRect(cnt)
        if  h>28:
            cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
            roi = thresh[y:y+h,x:x+w]
            roismall = cv2.resize(roi,(10,10))
            roismall = roismall.reshape((1,100))
            roismall = np.float32(roismall)
            retval, results, neigh_resp, dists = model.find_nearest(roismall, k = 1)
            string = str(int((results[0][0])))
            cv2.putText(out,string,(x,y+h),0,1,(0,255,0))

cv2.imshow('im',im)
cv2.imshow('out',out)
cv2.waitKey(0)

And it worked, below is the result I got:

Here it worked with 100% accuracy. I assume this is because all the digits are of the same kind and the same size.

But anyway, this is a good start to go for beginners (I hope so).

It sounds like you want to extend the jQuery object via it's prototype (aka write a jQuery plugin). This would mean that every new object created through calling the jQuery function ($(selector/DOM element)) would have this method.

Here is a very simple example:

$.fn.myFunction = function () {
    alert('it works');
};

Using This Helper For Dynamic Template Loading

//  get  Template 
    function get_template($template_name, $vars = array(), $return = FALSE) {
        $CI = & get_instance();

        $content = "";
        $last = $CI - > uri - > total_segments();

        if ($CI - > uri - > segment($last) != 'tab') {
            $content = $CI - > load - > view('Header', $vars, $return);
            $content. = $CI - > load - > view('Sidebar', $vars, $return);

        }

        if ($return) {
            return $content;
        }

Here's an example of the string "abc" repeated 3 times:

#include <iostream>
#include <sstream>
#include <algorithm>
#include <string>
#include <iterator>

using namespace std;

int main() {
    ostringstream repeated;
    fill_n(ostream_iterator<string>(repeated), 3, string("abc"));
    cout << "repeated: " << repeated.str() << endl;  // repeated: abcabcabc
    return 0;
}

Are you sure you're using the correct proxy as system properties?

Also if you are using 1.5 or 1.6 you could pass a java.net.Proxy instance to the openConnection() method. This is more elegant imo:

//Proxy instance, proxy ip = 10.0.0.1 with port 8080
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("10.0.0.1", 8080));
conn = new URL(urlString).openConnection(proxy);

getClass().getProtectionDomain().getCodeSource().getLocation();

You would do something like that using Google API.

Please note you must include the google maps library for this to work. Google geocoder returns a lot of address components so you must make an educated guess as to which one will have the city.

"administrative_area_level_1" is usually what you are looking for but sometimes locality is the city you are after.

Anyhow - more details on google response types can be found here and here.

As the message says, you have a task which threw an unhandled exception.

Turn on Break on All Exceptions (Debug, Exceptions) and rerun the program.
This will show you the original exception when it was thrown in the first place.

(comment appended): In VS2015 (or above). Select Debug > Options > Debugging > General and unselect the "Enable Just My Code" option.

What's the problem with using for loop inside, just like outside?

for (int j = i + 1; j < list.size(); ++j) {
    ...
}

In general, since Java 5, I used iterators only once or twice.

Setting the slice to nil is the best way to clear a slice. nil slices in go are perfectly well behaved and setting the slice to nil will release the underlying memory to the garbage collector.

See playground

package main

import (
    "fmt"
)

func dump(letters []string) {
    fmt.Println("letters = ", letters)
    fmt.Println(cap(letters))
    fmt.Println(len(letters))
    for i := range letters {
        fmt.Println(i, letters[i])
    }
}

func main() {
    letters := []string{"a", "b", "c", "d"}
    dump(letters)
    // clear the slice
    letters = nil
    dump(letters)
    // add stuff back to it
    letters = append(letters, "e")
    dump(letters)
}

Prints

letters =  [a b c d]
4
4
0 a
1 b
2 c
3 d
letters =  []
0
0
letters =  [e]
1
1
0 e

Note that slices can easily be aliased so that two slices point to the same underlying memory. The setting to nil will remove that aliasing.

This method changes the capacity to zero though.

First of all, it has to do with usability. If you use inheritance, the Team class will expose behavior (methods) that are designed purely for object manipulation. For example, AsReadOnly() or CopyTo(obj) methods make no sense for the team object. Instead of the AddRange(items) method you would probably want a more descriptive AddPlayers(players) method.

If you want to use LINQ, implementing a generic interface such as ICollection<T> or IEnumerable<T> would make more sense.

As mentioned, composition is the right way to go about it. Just implement a list of players as a private variable.

I realize this is an old post, but it ranks high in Google, so I'm adding what I figured out for MY problem. If you have a mix of table types (e.g. MyISAM and InnoDB), you will get this error as well. In this case, InnoDB is the default table type, but one table needed fulltext searching so it was migrated to MyISAM. In this situation, you cannot create a foreign key in the InnoDB table that references the MyISAM table.

Push down the whole button. I suggest this it is looking nice in button.

#button:active {
    position: relative;
    top: 1px;
}

if you only want to push text increase top-padding and decrease bottom padding. You can also use line-height.

Go to your project path on CMD(command Prompt) and execute the following command:-

set FLASK_APP=ABC.py

SET FLASK_ENV=development

flask run -h [yourIP] -p 8080

you will get following o/p on CMD:-

• Serving Flask app "expirement.py" (lazy loading)
  • Environment: development
  • Debug mode: on
  • Restarting with stat
  • Debugger is active!
  • Debugger PIN: 199-519-700
  • Running on http://[yourIP]:8080/ (Press CTRL+C to quit)

Now you can access your flask app on another machine using http://[yourIP]:8080/ url

var option_user_selection = document.getElementById("maincourse").options[document.getElementById("maincourse").selectedIndex ].text

In terms of C# language, the following may not make much sense. And this is not a direct answer to the question. But following is what I did in one of my business scenarios.

char? myCharFromUI = Convert.ToChar(" ");
string myStringForDatabaseInsert = myCharFromUI.ToString().Trim();
if (String.IsNullOrEmpty(myStringForDatabaseInsert.Trim()))
{
    Console.Write("Success");
}

The null and white space had different business flows in my project. While inserting into database, I need to insert empty string to the database if it is white space.

You can also use array concatenation:

a = [2, 3]
[1] + a
=> [1, 2, 3]

This creates a new array and doesn't modify the original.

Instead of catching the error, wouldn't it be possible to test in or before the myplotfunction() function first if the error will occur (i.e. if the breaks are unique) and only plot it for those cases where it won't appear?!

C++ is a language and Visual C++ is a compiler for that language. Certainly, it (and every other compiler) introduces tiny modifications to the language, but the language recognized is mainly the same.

You need to set the password for root@localhost to be blank. There are two ways:

1. The MySQL SET PASSWORD command:

   SET PASSWORD FOR root@localhost=PASSWORD('');
   

2. Using the command-line mysqladmin tool:

   mysqladmin -u root -pType_in_your_current_password_here password ''
   

This regex should do it.

\b[a-z]+-[a-z]+\b 

\b indicates a word-boundary.

$(document).height() // - $('body').offset().top

and / or

$(window).height()

See Stack Overflow question How to get the height of a body element.

Try this to find the height of the body in jQuery:

if $("body").height()

It doesn't have a value if Firebug. Perhaps that's the problem.

The best choice to me was to create a directive to do the work, because $location.hash() and $anchorScroll() hijack the URL creating lots of problems to my SPA routing.

MyModule.directive('myAnchor', function() {
  return {
    restrict: 'A',
    require: '?ngModel',
    link: function(scope, elem, attrs, ngModel) {
      return elem.bind('click', function() {
        //other stuff ...
        var el;
        el = document.getElementById(attrs['myAnchor']);
        return el.scrollIntoView();
      });      
    }
  };
});

You can use GroupBy with anonymous type, and then get First:

list.GroupBy(e => new { 
                          empLoc = e.empLoc, 
                          empPL = e.empPL, 
                          empShift = e.empShift 
                       })

    .Select(g => g.First());

 $('mainCheckBox').click(function(){
    if($(this).prop('checked')){
        $('Id or Class of checkbox').prop('checked', true);
    }else{
        $('Id or Class of checkbox').prop('checked', false);
    }
});

Most of the examples above show how to reuse an existing comparable object in the compareTo function. If you would like to implement your own compareTo when you want to compare two objects of the same class, say an AirlineTicket object that you would like to sort by price(less is ranked first), followed by number of stopover (again, less is ranked first), you would do the following:

class AirlineTicket implements Comparable<Cost>
{
    public double cost;
    public int stopovers;
    public AirlineTicket(double cost, int stopovers)
    {
        this.cost = cost; this.stopovers = stopovers ;
    }

    public int compareTo(Cost o)
    {
        if(this.cost != o.cost)
          return Double.compare(this.cost, o.cost); //sorting in ascending order. 
        if(this.stopovers != o.stopovers)
          return this.stopovers - o.stopovers; //again, ascending but swap the two if you want descending
        return 0;            
    }
}

This should be OK

   $value = explode(".", $value);
   $extension = strtolower(array_pop($value));   //Line 32
   // the file name is before the last "."
   $fileName = array_shift($value);  //Line 34

The Standard Library provides an input function called ws, which consumes whitespace from an input stream. You can use it like this:

std::string s;
std::getline(std::cin >> std::ws, s);

I'd do something like:

private IEnumerable<string> DoWork(IEnumerable<string> data)
{
    List<string> newData = new List<string>();
    foreach(string item in data)
    {
        newData.Add(item + "roxxors");
    }
    return newData;
}

Simple stuff :)

Adapted from this answer:

function scroll(y, duration) {

    var initialY = document.documentElement.scrollTop || document.body.scrollTop;
    var baseY = (initialY + y) * 0.5;
    var difference = initialY - baseY;
    var startTime = performance.now();

    function step() {
        var normalizedTime = (performance.now() - startTime) / duration;
        if (normalizedTime > 1) normalizedTime = 1;

        window.scrollTo(0, baseY + difference * Math.cos(normalizedTime * Math.PI));
        if (normalizedTime < 1) window.requestAnimationFrame(step);
    }
    window.requestAnimationFrame(step);
}

This should allow you to smoothly scroll (cosine function) from anywhere to the specified "y".

I think you are forgetting about the border. Having a one-pixel-wide border on the Div will take away two pixels of total length. Therefore it will appear as though the div is two pixels shorter than it actually is.

Doubles are just like floats, except for the fact that they are twice as large. This allows for a greater accuracy.

Try this C# Reflection link.

Note I think that BindingFlags.Instance and BindingFlags.Static are exclusive.

var fs = require('fs');
var dir = './tmp';

if (!fs.existsSync(dir)){
    fs.mkdirSync(dir);
}

As others have already mentioned, running PHP as a daemon is quite easy, and can be done using a single line of command. But the actual problem is keeping it running and managing it. I've had the same problem quite some time ago and although there are plenty of solutions already available, most of them have lots of dependencies or are difficult to use and not suitable for basic usages. I wrote a shell script that can manage a any process/application including PHP cli scripts. It can be set as a cronjob to start the application and will contain the application and manage it. If it's executed again, for example via the same cronjob, it check if the app is running or not, if it does then simply exits and let its previous instance continue managing the application.

I uploaded it to github, feel free to use it : https://github.com/sinasalek/EasyDeamonizer

EasyDeamonizer

Simply watches over your application (start, restart, log, monitor, etc). a generic script to make sure that your appliation remains running properly. Intentionally it uses process name instread of pid/lock file to prevent all its side effects and keep the script as simple and as stirghforward as possible, so it always works even when EasyDaemonizer itself is restarted. Features

• Starts the application and optionally a customized delay for each start
• Makes sure that only one instance is running
• Monitors CPU usage and restarts the app automatically when it reaches the defined threshold
• Setting EasyDeamonizer to run via cron to run it again if it's halted for any reason
• Logs its activity

RegexBuddy is telling me if you want to include it at the beginning, this is the correct syntax:

"(?i)\\b(\\w+)\\b(\\s+\\1)+\\b"

Try this

COALESCE(NULLIF(Address.COUNTRY,''), 'United States')

Take a look at this one (c) Tanel Poder. You may either run it from your glogin.sql (so these settings will update each time you connect, or just run it manually. Notice host title command - it changes your sql*plus console window title with session information - extremely useful with many windows open simultaneously.

Approach 2 will always return a count that matches your result set.

I suggest you link the sub-query to your outer query though, to guarantee that the condition on your count matches the condition on the dataset.

SELECT 
  mt.my_row,
 (SELECT COUNT(mt2.my_row) FROM my_table mt2 WHERE mt2.foo = mt.foo) as cnt
FROM my_table mt
WHERE mt.foo = 'bar';

Version Code - It's a positive integer that's used for comparison with other version codes. It's not shown to the user, it's just for record-keeping in a way. You can set it to any integer you like but it's suggested that you linearly increment it for successive versions.

Version Name - This is the version string seen by the user. It isn't used for internal comparisons or anything, it's just for users to see.

For example: Say you release an app, its initial versionCode could be 1 and versionName could also be 1. Once you make some small changes to the app and want to publish an update, you would set versionName to "1.1" (since the changes aren't major) while logically your versionCode should be 2 (regardless of size of changes).

Say in another condition you release a completely revamped version of your app, you could set versionCode and versionName to "2".

Hope that helps.

For compatibility when ajax is not available, set .val('') or it will resend the last ajax-uploaded file that is still present in the input. The following should properly clear the input whilst retaining .on() events:

var input = $("input[type='file']");
input.html(input.html()).val('');

Dependencies.

var fs = require('fs');
var path = require('path');

Definition.

// String -> [String]
function fileList(dir) {
  return fs.readdirSync(dir).reduce(function(list, file) {
    var name = path.join(dir, file);
    var isDir = fs.statSync(name).isDirectory();
    return list.concat(isDir ? fileList(name) : [name]);
  }, []);
}

Usage.

var DIR = '/usr/local/bin';

// 1. List all files in DIR
fileList(DIR);
// => ['/usr/local/bin/babel', '/usr/local/bin/bower', ...]

// 2. List all file names in DIR
fileList(DIR).map((file) => file.split(path.sep).slice(-1)[0]);
// => ['babel', 'bower', ...]

Please note that fileList is way too optimistic. For anything serious, add some error handling.

Just pass in the current Context to the Adapter constructor and store it as a field. Then inside the onClick you can use that context to call startActivity().

pseudo-code

public class MyAdapter extends Adapter {
     private Context context;

     public MyAdapter(Context context) {
          this.context = context;     
     }

     public View getView(...){
         View v;
         v.setOnClickListener(new OnClickListener() {
             void onClick() {
                 context.startActivity(...);
             }
         });
     }
}

You'll have to resort to XHTML or HTML 4.01 for this. Although iframe is still there in HTML5, its use is not recommended for embedding content meant for the user.

And be sure to tell your teacher that frames haven't been state-of-the-art since the late nineties. They have no place in any kind of education at all, except possibly for historical reasons.

If the dicts have identical sets of keys and you need all those prints for any value difference, there isn't much you can do; maybe something like:

diffkeys = [k for k in dict1 if dict1[k] != dict2[k]]
for k in diffkeys:
  print k, ':', dict1[k], '->', dict2[k]

pretty much equivalent to what you have, but you might get nicer presentation for example by sorting diffkeys before you loop on it.

Answers posted here did not help, but the following link did:

http://developer.android.com/training/basics/fragments/communicating.html

Define an Interface

public class HeadlinesFragment extends ListFragment {
    OnHeadlineSelectedListener mCallback;

    // Container Activity must implement this interface
    public interface OnHeadlineSelectedListener {
        public void onArticleSelected(int position);
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        // This makes sure that the container activity has implemented
        // the callback interface. If not, it throws an exception
        try {
            mCallback = (OnHeadlineSelectedListener) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                    + " must implement OnHeadlineSelectedListener");
        }
    }

    ...
}

For example, the following method in the fragment is called when the user clicks on a list item. The fragment uses the callback interface to deliver the event to the parent activity.

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    // Send the event to the host activity
    mCallback.onArticleSelected(position);
}

Implement the Interface

For example, the following activity implements the interface from the above example.

public static class MainActivity extends Activity
        implements HeadlinesFragment.OnHeadlineSelectedListener{
    ...

    public void onArticleSelected(int position) {
        // The user selected the headline of an article from the HeadlinesFragment
        // Do something here to display that article
    }
}

Update for API 23: 8/31/2015

Overrided method onAttach(Activity activity) is now deprecated in android.app.Fragment, code should be upgraded to onAttach(Context context)

@Override
public void onAttach(Context context) {
    super.onAttach(context);
}


@Override
public void onStart() {
    super.onStart();
    try {
        mListener = (OnFragmentInteractionListener) getActivity();
    } catch (ClassCastException e) {
        throw new ClassCastException(getActivity().toString()
                + " must implement OnFragmentInteractionListener");
    }
}

Wrong quoting: (and missing option closing tag xd)

$out.='<option value="'.$key.'">'.$value["name"].'</option>';

 public Person SomeMethod(string fName)
        {
            var con = ConfigurationManager.ConnectionStrings["Yourconnection"].ToString();

            Person matchingPerson = new Person();
            using (SqlConnection myConnection = new SqlConnection(con))
            {
                string oString = "Select * from Employees where FirstName=@fName";
                SqlCommand oCmd = new SqlCommand(oString, myConnection);
                oCmd.Parameters.AddWithValue("@Fname", fName);           
                myConnection.Open();
                using (SqlDataReader oReader = oCmd.ExecuteReader())
                {
                    while (oReader.Read())
                    {    
                        matchingPerson.firstName = oReader["FirstName"].ToString();
                        matchingPerson.lastName = oReader["LastName"].ToString();                       
                    }

                    myConnection.Close();
                }               
            }
            return matchingPerson;
        }

Few things to note here: I used a parametrized query, which makes your code safer. The way you are making the select statement with the "where x = "+ Textbox.Text +"" part opens you up to SQL injection.

I've changed this to:

  "Select * from Employees where FirstName=@fName"
  oCmd.Parameters.AddWithValue("@fname", fName);  

So what this block of code is going to do is:

Execute an SQL statement against your database, to see if any there are any firstnames matching the one you provided. If that is the case, that person will be stored in a Person object (see below in my answer for the class). If there is no match, the properties of the Person object will be null.

Obviously I don't exactly know what you are trying to do, so there's a few things to pay attention to: When there are more then 1 persons with a matching name, only the last one will be saved and returned to you. If you want to be able to store this data, you can add them to a List<Person> .

Person class to make it cleaner:

 public class Person
    {
            public string firstName { get; set; }
            public string lastName { get; set; }
    }

Now to call the method:

Person x = SomeMethod("John");

You can then fill your textboxes with values coming from the Person object like so:

txtLastName.Text = x.LastName;

The dynamicType.printClassName code is from an example in the Swift book. There's no way I know of to directly grab a custom class name, but you can check an instances type using the is keyword as shown below. This example also shows how to implement a custom className function, if you really want the class name as a string.

class Shape {
    class func className() -> String {
        return "Shape"
    }
}

class Square: Shape {
    override class func className() -> String {
        return "Square"
    }
}

class Circle: Shape {
    override class func className() -> String {
        return "Circle"
    }
}

func getShape() -> Shape {
    return Square() // hardcoded for example
}

let newShape: Shape = getShape()
newShape is Square // true
newShape is Circle // false
newShape.dynamicType.className() // "Square"
newShape.dynamicType.className() == Square.className() // true

Note:
that subclasses of NSObject already implement their own className function. If you're working with Cocoa, you can just use this property.

class MyObj: NSObject {
    init() {
        super.init()
        println("My class is \(self.className)")
    }
}
MyObj()

Same thing, Just start the table name with # or ##:

CREATE TABLE #TemporaryTable          -- Local temporary table - starts with single #
(
    Col1 int,
    Col2 varchar(10)
    ....
);

CREATE TABLE ##GlobalTemporaryTable   -- Global temporary table - note it starts with ##.
(
    Col1 int,
    Col2 varchar(10)
    ....
);

Temporary table names start with # or ## - The first is a local temporary table and the last is a global temporary table.

Here is one of many articles describing the differences between them.

Assuming I've guessed the pattern correctly (alternating increments of 1 and 3), this should produce the desired result:

def sequence():
    res = []
    diff = 1
    x = 1
    while x <= 100:
        res.append(x)
        x += diff
        diff = 3 if diff == 1 else 1
    return ', '.join(res)

The following simple steps help me:

First, initialize the repository to work with Git, so that any file changes are tracked:

git init

Then, check that the remote repository that you want to associate with the alias origin exists, if not create it in git first.

$ git ls-remote https://github.com/repo-owner/repo-name.git/

If it exists, associate it with the remote "origin":

git remote add origin https://github.com:/repo-owner/repo-name.git

and check to which URL, the remote "origin" belongs to by using git remote -v:

$ git remote -v
origin  https://github.com:/repo-owner/repo-name.git (fetch)
origin  https://github.com:/repo-owner/repo-name.git (push)

Next, verify if your origin is properly aliased as follows:

$ cat ./.git/config
:
[remote "origin"]
        url = https://github.com:/repo-owner/repo-name.git
        fetch = +refs/heads/*:refs/remotes/origin/*
:

You need to see this section [remote "origin"]. You can consider to use GitHub Desktop available for both Windows and MacOS, which help me to automatically populate the missing section/s in ~./git/config file OR you can manually add it, not great, but hey it works!

[Optional]
You might also want to change the origin alias to make it more intuitive, especially if you are working with multiple origin:

git remote rename origin mynewalias

or even remove it:

git remote rm origin

Finally, on your first push, if you want master in that repository to be your default upstream. you may want to add the -u parameter

git add .
git commit -m 'First commit'
git push -u origin master

Instead of override you can add another class to the element and then you have an extra abilities. for example:

HTML

<div class="style1 style2"></div>

CSS

//only style for the first stylesheet
.style1 {
   width: 100%;      
}
//only style for second stylesheet
.style2 {
   width: 50%;     
}
//override all
.style1.style2 { 
   width: 70%;
}

Use subprocess.Popen:

import subprocess
process = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = process.communicate()
print(out)

Note that communicate blocks until the process terminates. You could use process.stdout.readline() if you need the output before it terminates. For more information see the documentation.

To easily debug Ruby shell script, just change its first line from:

#!/usr/bin/env ruby

to:

#!/usr/bin/env ruby -rdebug

Then every time when debugger console is shown, you can choose:

• c for Continue (to the next Exception, breakpoint or line with: debugger),
• n for Next line,
• w/where to Display frame/call stack,
• l to Show the current code,
• cat to show catchpoints.
• h for more Help.

See also: Debugging with ruby-debug, Key shortcuts for ruby-debug gem.

In case the script just hangs and you need a backtrace, try using lldb/gdb like:

echo 'call (void)rb_backtrace()' | lldb -p $(pgrep -nf ruby)

and then check your process foreground.

Replace lldb with gdb if works better. Prefix with sudo to debug non-owned process.

is all this really necessary, human perception and CRT vs LCD will vary, but the R G B intensity does not, Why not L = (R + G + B)/3 and set the new RGB to L, L, L?

I solve such queries using this pattern:

SELECT *
FROM t
WHERE t.field=(
  SELECT MAX(t.field) 
  FROM t AS t0 
  WHERE t.group_column1=t0.group_column1
    AND t.group_column2=t0.group_column2 ...)

That is it will select records where the value of a field is at its max value. To apply it to your query I used the common table expression so that I don't have to repeat the JOIN twice:

WITH site_history AS (
  SELECT sites.siteName, sites.siteIP, history.date
  FROM sites
  JOIN history USING (siteName)
)
SELECT *
FROM site_history h
WHERE date=(
  SELECT MAX(date) 
  FROM site_history h0 
  WHERE h.siteName=h0.siteName)
ORDER BY siteName

It's important to note that it works only if the field we're calculating the maximum for is unique. In your example the date field should be unique for each siteName, that is if the IP can't be changed multiple times per millisecond. In my experience this is commonly the case otherwise you don't know which record is the newest anyway. If the history table has an unique index for (site, date), this query is also very fast, index range scan on the history table scanning just the first item can be used.

OK... I realize this thread is old and overcrowded, but in case someone comes in like I did struggling to get their og:image tag to work right in Facebook, here's the trick that worked for me:

do NOT use this link:

https://developers.facebook.com/tools/debug/sharing/?q=https%3A%2F%2Fwww.google.com

to work through your problem. Or if you do, immediately scroll down to the bottom and click on Scrape VIA API.

https://developers.facebook.com/tools/explorer/?method=POST&path=%3Fscrape%3Dtrue%26id%3Dhttps%3A%2F%2Fwww.google.com&version=v5.0

There are errors displayed in the explorer tool that are NOT shown in the "debug" tool. Maddening!!! (in my case, a space in the image filename knocked my image out silently in the debug tool, but it showed the error in the explorer tool).

Have a look at the config file.

Repository > Repository Settings > Edit config file.

Check if the [user] section exists. If the user section is missing, add it.

Example:

[user]
name = "your name"
email = "your email"

Just add them to the parameter string.

window.open(this.href,'targetWindow','toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=350,height=250')

Just use the split function. It returns a list, so you can keep the first element:

>>> s1.split(':')
['Username', ' How are you today?']
>>> s1.split(':')[0]
'Username'

I am aware there are already several answers, but I added this, as this adds substantial information about the decimal places and hence the asked maximum length.

The length of latitude and langitude depend on precision. The absolute maximum length for each is:

• Latitude: 12 characters (example: -90.00000001)
• Longitude: 13 characters (example: -180.00000001)

For both holds: a maximum of 8 decial places is possible (though not commonly used).

Explanation for the dependency on precision:

See the full table at Decimal degrees article on Wikipedia

The term 'slug' comes from the world of newspaper production.

It's an informal name given to a story during the production process. As the story winds its path from the beat reporter (assuming these even exist any more?) through to editor through to the "printing presses", this is the name it is referenced by, e.g., "Have you fixed those errors in the 'kate-and-william' story?".

Some systems (such as Django) use the slug as part of the URL to locate the story, an example being www.mysite.com/archives/kate-and-william.

Even Stack Overflow itself does this, with the GEB-ish^(a) self-referential https://stackoverflow.com/questions/427102/what-is-a-slug-in-django/427201#427201, although you can replace the slug with blahblah and it will still find it okay.

It may even date back earlier than that, since screenplays had "slug lines" at the start of each scene, which basically sets the background for that scene (where, when, and so on). It's very similar in that it's a precis or preamble of what follows.

On a Linotype machine, a slug was a single line piece of metal which was created from the individual letter forms. By making a single slug for the whole line, this greatly improved on the old character-by-character compositing.

Although the following is pure conjecture, an early meaning of slug was for a counterfeit coin (which would have to be pressed somehow). I could envisage that usage being transformed to the printing term (since the slug had to be pressed using the original characters) and from there, changing from the 'piece of metal' definition to the 'story summary' definition. From there, it's a short step from proper printing to the online world.

^(a) "Godel Escher, Bach", by one Douglas Hofstadter, which I (at least) consider one of the great modern intellectual works. You should also check out his other work, "Metamagical Themas".

Instead of os.path.isfile, suggested by others, I suggest using os.path.exists, which checks for anything with that name, not just whether it is a regular file.

Thus:

if not os.path.exists(filename):
    file(filename, 'w').close()

Alternatively:

file(filename, 'w+').close()

The latter will create the file if it exists, but not otherwise. It will, however, fail if the file exists, but you don't have permission to write to it. That's why I prefer the first solution.

I was just investigating this issue (so I know this question was published almost 3 years ago, but maybe it will help someone... ) but it seems that a better option is to place the code inside the RowPrePaint event so that you don't have to traverse every row, only those that get painted (so it will perform much better on large amount of data:

Attach to the event

this.dataGridView1.RowPrePaint 
    += new System.Windows.Forms.DataGridViewRowPrePaintEventHandler(
        this.dataGridView1_RowPrePaint);

The event code

private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)
{
    if (Convert.ToInt32(dataGridView1.Rows[e.RowIndex].Cells[7].Text) < Convert.ToInt32(dataGridView1.Rows[e.RowIndex].Cells[10].Text)) 
    {
        dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Beige;
    }
}

You can do this with a Correlated Subquery (That is a subquery wherein you reference a field in the main query). In this case:

SELECT * 
FROM yourtable t1
WHERE date = (SELECT max(date) from yourtable WHERE id = t1.id)

Here we give the yourtable table an alias of t1 and then use that alias in the subquery grabbing the max(date) from the same table yourtable for that id.

You can easily write a bit code that will read in a file. You can either assume one sql statement per line, or assume the ;

So, assuming you have a text file such as:

insert into tblTest (t1) values ('2000');

update tbltest set t1 = '2222'
       where id = 5;


insert into tblTest (t1,t2,t3) 
       values ('2001','2002','2003');

Note the in the above text file we free to have sql statements on more then one line.

the code you can use to read + run the above script is:

Sub SqlScripts()

   Dim vSql       As Variant
   Dim vSqls      As Variant
   Dim strSql     As String
   Dim intF       As Integer

   intF = FreeFile()
   Open "c:\sql.txt" For Input As #intF
   strSql = input(LOF(intF), #intF)
   Close intF
   vSql = Split(strSql, ";")

   On Error Resume Next
   For Each vSqls In vSql
      CurrentDb.Execute vSqls
   Next

End Sub

You could expand on placing some error msg if the one statement don't work, such as

if err.number <> 0 then
   debug.print "sql err" & err.Descripiton & "-->" vSqls
end dif

Regardless, the above split() and string read does alow your sql to be on more then one line...

Use the formatting options available to you, use the Decimal format string. It is far more flexible and requires little to no maintenance compared to direct string manipulation.

To get the string representation using at least 4 digits:

int length = 4;
int number = 50;
string asString = number.ToString("D" + length); //"0050"

It seems as though the "sr-only" element and its styles inside of the table are what's causing this bug. At least I had the same issue and after months of banging our head against the wall that's what we determined the cause was, though I still don't understand why. Adding left:0 to the "sr-only" styles fixed it.

I like to use the handy process outlined here to build connection strings using a .udl file. This allows you to test them from within the udl file to ensure that you can connect before you run any code.

Hope that helps.

I do not see it mentioned here, but a command that i use often and that helps me to have a bird's eye view on all groups, topics, partitions, offsets, lags, consumers, etc

kafka-consumer-groups.bat --bootstrap-server localhost:9092 --describe --all-groups

A sample would look like this:

GROUP TOPIC PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG CONSUMER-ID HOST CLIENT-ID
Group Topic 2          7               7               0   <SOME-ID>   XXXX <SOME-ID>
:
:

The most important column is the LAG, where for a healthy platform, ideally it should be 0(or nearer to 0 or a low number for high throughput) - at all times. So make sure you monitor it!!! ;-).

P.S:
An interesting article on how you can monitor the lag can be found here.

In my case, it was neither systemd nor a cron job, but it was snap. So I had to run:

sudo snap stop docker
sudo snap remove docker

... and the last command actually never ended, I don't know why: this snap thing is really a pain. So I also ran:

sudo apt purge snap

:-)

Simple solution:

<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>

This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.

Click here this is a good tutorial for both window/ubuntu.

1. apktool1.5.1.jar download from here.

2. apktool-install-linux-r05-ibot download from here.

3. dex2jar-0.0.9.15.zip download from here.

4. jd-gui-0.3.3.linux.i686.tar.gz (java de-complier) download from here.

5. framework-res.apk ( Located at your android device /system/framework/)

Procedure:

1. Rename the .apk file and change the extension to .zip ,

it will become .zip.

2. Then extract .zip.

3. Unzip downloaded dex2jar-0.0.9.15.zip file , copy the contents and paste it to unzip folder.

4. Open terminal and change directory to unzip “dex2jar-0.0.9.15 “

– cd – sh dex2jar.sh classes.dex (result of this command “classes.dex.dex2jar.jar” will be in your extracted folder itself).

5. Now, create new folder and copy “classes.dex.dex2jar.jar” into it.

6. Unzip “jd-gui-0.3.3.linux.i686.zip“ and open up the “Java Decompiler” in full screen mode.

7. Click on open file and select “classes.dex.dex2jar.jar” into the window.

8. “Java Decompiler” and go to file > save and save the source in a .zip file.

9. Create “source_code” folder.

10. Extract the saved .zip and copy the contents to “source_code” folder.

11. This will be where we keep your source code.

12. Extract apktool1.5.1.tar.bz2 , you get apktool.jar

13. Now, unzip “apktool-install-linux-r05-ibot.zip”

14. Copy “framework-res.apk” , “.apk” and apktool.jar

15. Paste it to the unzip “apktool-install-linux-r05-ibot” folder (line no 13).

16. Then open terminal and type:

    – cd

    – chown -R : ‘apktool.jar’

    – chown -R : ‘apktool’

    – chown -R : ‘aapt’

    – sudo chmod +x ‘apktool.jar’

    – sudo chmod +x ‘apktool’

    – sudo chmod +x ‘aapt’

    – sudo mv apktool.jar /usr/local/bin

    – sudo mv apktool /usr/local/bin

    – sudo mv aapt /usr/local/bin

    – apktool if framework-res.apk – apktool d .apk

Well, how about this !!

This code calculates both row and column count in a csv file. Try this out !!

    static int[] getRowsColsNo() {
    Scanner scanIn = null;
    int rows = 0;
    int cols = 0;
    String InputLine = "";
    try {
        scanIn = new Scanner(new BufferedReader(
                new FileReader("filename.csv")));
        scanIn.useDelimiter(",");
        while (scanIn.hasNextLine()) {
            InputLine = scanIn.nextLine();
            String[] InArray = InputLine.split(",");
            rows++;
            cols = InArray.length;
        }

    } catch (Exception e) {
        System.out.println(e);
    }
    return new int[] { rows, cols };
}

In Support Library 27.1.0 and later, Google has introduced new methods requireContext() and requireActivity() methods.

Eg:ContextCompat.getColor(requireContext(), R.color.soft_gray)

More info here

 $(function () {
        function checkPendingRequest() {
            if ($.active > 0) {
                window.setTimeout(checkPendingRequest, 1000);
                //Mostrar peticiones pendientes ejemplo: $("#control").val("Peticiones pendientes" + $.active);
            }
            else {

                alert("No hay peticiones pendientes");

            }
        };

        window.setTimeout(checkPendingRequest, 1000);
 });

C++ has no built-in concepts of interfaces. You can implement it using abstract classes which contains only pure virtual functions. Since it allows multiple inheritance, you can inherit this class to create another class which will then contain this interface (I mean, object interface :) ) in it.

An example would be something like this -

class Interface
{
public:
    Interface(){}
    virtual ~Interface(){}
    virtual void method1() = 0;    // "= 0" part makes this method pure virtual, and
                                   // also makes this class abstract.
    virtual void method2() = 0;
};

class Concrete : public Interface
{
private:
    int myMember;

public:
    Concrete(){}
    ~Concrete(){}
    void method1();
    void method2();
};

// Provide implementation for the first method
void Concrete::method1()
{
    // Your implementation
}

// Provide implementation for the second method
void Concrete::method2()
{
    // Your implementation
}

int main(void)
{
    Interface *f = new Concrete();

    f->method1();
    f->method2();

    delete f;

    return 0;
}

From the Java Tutorial:

Nested classes are divided into two categories: static and non-static. Nested classes that are declared static are simply called static nested classes. Non-static nested classes are called inner classes.

Static nested classes are accessed using the enclosing class name:

OuterClass.StaticNestedClass

For example, to create an object for the static nested class, use this syntax:

OuterClass.StaticNestedClass nestedObject = new OuterClass.StaticNestedClass();

Objects that are instances of an inner class exist within an instance of the outer class. Consider the following classes:

class OuterClass {
    ...
    class InnerClass {
        ...
    }
}

An instance of InnerClass can exist only within an instance of OuterClass and has direct access to the methods and fields of its enclosing instance.

To instantiate an inner class, you must first instantiate the outer class. Then, create the inner object within the outer object with this syntax:

OuterClass outerObject = new OuterClass()
OuterClass.InnerClass innerObject = outerObject.new InnerClass();

see: Java Tutorial - Nested Classes

For completeness note that there is also such a thing as an inner class without an enclosing instance:

class A {
  int t() { return 1; }
  static A a =  new A() { int t() { return 2; } };
}

Here, new A() { ... } is an inner class defined in a static context and does not have an enclosing instance.

If you want to migrate all branches and tags you should use the following commands:

git clone --mirror [oldUrl]

to clone the old repo with all branches

cd the_repo
git remote add remoteName newRepoUrl

to setup a new remote

git push -f --tags remoteName refs/heads/*:refs/heads/*

to push all refs under refs/heads (which is probably what you want)

Step: 1 Your Html, First Store the value in your localstorage using javascript then add the line like below ,this is where you going to display the value in your html, my example is based on boostrap :

<label for="stringName" class="cols-sm-2 control-
label">@Html.Hidden("stringName", "")</label>

Step:2 Javascript

 $('#stringName').replaceWith(localStorage.getItem("itemName"));

This is a very low-level exception, which is ORA-17410.

It may happen for several reasons:

1. A temporary problem with networking.

2. Wrong JDBC driver version.

3. Some issues with a special data structure (on database side).

4. Database bug.

In my case, it was a bug we hit on the database, which needs to be patched.

You may also be missing using namespace std;

IF it is in mac then it's all about IP of x86_64-apple-darwin13.4.0. If you follow errors it would be something related to x86_64-apple-darwin13.4.0. Add

127.0.0.1 x86_64-apple-darwin13.4.0

to /etc/hosts file. Then the problem is gone

default_scope

This works for Rails 4+:

class Book < ActiveRecord::Base
  default_scope { order(created_at: :desc) }
end

For Rails 2.3, 3, you need this instead:

default_scope order('created_at DESC')

For Rails 2.x:

default_scope :order => 'created_at DESC'

Where created_at is the field you want the default sorting to be done on.

Note: ^ASC is the code to use for Ascending and _DESC is for descending (desc, NOT dsc !).

scope

Once you're used to that you can also use scope:

class Book < ActiveRecord::Base
  scope :confirmed, :conditions => { :confirmed => true }
  scope :published, :conditions => { :published => true }
end

For Rails 2 you need named_scope.

:published scope gives you Book.published instead of Book.find(:published => true).

Since Rails 3 you can 'chain' those methods together by concatenating them with periods between them, so with the above scopes you can now use Book.published.confirmed.

With this method, the query is not actually executed until actual results are needed (lazy evaluation), so 7 scopes could be chained together but only resulting in 1 actual database query, to avoid performance problems from executing 7 separate queries.

You can use a passed in parameter such as a date or a user_id (something that will change at run-time and so will need that 'lazy evaluation', with a lambda, like this:

scope :recent_books, lambda 
  { |since_when| where("created_at >= ?", since_when) }
  # Note the `where` is making use of AREL syntax added in Rails 3.

Finally you can disable default scope with:

Book.with_exclusive_scope { find(:all) } 

or even better:

Book.unscoped.all

which will disable any filter (conditions) or sort (order by).

Note that the first version works in Rails2+ whereas the second (unscoped) is only for Rails3+

So ... if you're thinking, hmm, so these are just like methods then..., yup, that's exactly what these scopes are!
They are like having def self.method_name ...code... end but as always with ruby they are nice little syntactical shortcuts (or 'sugar') to make things easier for you!

In fact they are Class level methods as they operate on the 1 set of 'all' records.

Their format is changing however, with rails 4 there are deprecation warning when using #scope without passing a callable object. For example scope :red, where(color: 'red') should be changed to scope :red, -> { where(color: 'red') }.

As a side note, when used incorrectly, default_scope can be misused/abused.
This is mainly about when it gets used for actions like where's limiting (filtering) the default selection (a bad idea for a default) rather than just being used for ordering results.
For where selections, just use the regular named scopes. and add that scope on in the query, e.g. Book.all.published where published is a named scope.

In conclusion, scopes are really great and help you to push things up into the model for a 'fat model thin controller' DRYer approach.

You can just use a sequence of x/10.0f and std::floor operations to have "math approach". Or you can also use boost::lexical_cast(the_number) to obtain a string and then you can simply do the_string.c_str()[i] to access the individual characters (the "string approach").

svn revert will undo any local changes you've made

You don't want use PreparedStatment with dynamic queries using IN clause at least your sure you're always under 5 variable or a small value like that but even like that I think it's a bad idea ( not terrible, but bad ). As the number of elements is large, it will be worse ( and terrible ).

Imagine hundred or thousand possibilities in your IN clause :

1. It's counter-productive, you lost performance and memory because you cache every time a new request, and PreparedStatement are not just for SQL injection, it's about performance. In this case, Statement is better.

2. Your pool have a limit of PreparedStatment ( -1 defaut but you must limit it ), and you will reach this limit ! and if you have no limit or very large limit you have some risk of memory leak, and in extreme case OutofMemory errors. So if it's for your small personnal project used by 3 users it's not dramatic, but you don't want that if you're in a big company and that you're app is used by thousand people and million request.

Some reading. IBM : Memory utilization considerations when using prepared statement caching

The ToString function has many overloads - the method group would be the group consisting of all the different overloads for that function.

The suggested method for communicating between fragments is to use callbacks\listeners that are managed by your main Activity.

I think the code on this page is pretty clear: http://developer.android.com/training/basics/fragments/communicating.html

You can also reference the IO 2012 Schedule app, which is designed to be a de-facto reference app. It can be found here: http://code.google.com/p/iosched/

Also, here is a SO question with good info: How to pass data between fragments

Lets consider you have a class name named Products and you have a IsActive field. just you need a create constructor :

Public class Products
{
    public Products()
    {
       IsActive = true;
    }
 public string Field1 { get; set; }
 public string Field2 { get; set; }
 public bool IsActive { get; set; }
}

Then your IsActive default value is True!

Edite :

if you want to do this with SQL use this command :

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Blog>()
        .Property(b => b.IsActive)
        .HasDefaultValueSql("true");
}

You could use a JSON serializer/deserializer like flexjson to do the conversion for you.

rm in within can be quite useful.

within(mtcars, rm(mpg, cyl, disp, hp))
#                     drat    wt  qsec vs am gear carb
# Mazda RX4           3.90 2.620 16.46  0  1    4    4

You can change the 'template/popover/popover.html' in file 'ui-bootstrap-tpls-0.11.0.js' Write: "bind-html-unsafe" instead of "ng-bind"

It will show all popover with html. *its unsafe html. Use only if you trust the html.

If you want to work with JAX-RS (e.g. RESTEasy) try this:

@Path("/pic")
public Response get(@QueryParam("url") final String url) {
    String picUrl = URLDecoder.decode(url, "UTF-8");

    return Response.ok(sendPicAsStream(picUrl))
            .header(HttpHeaders.CONTENT_TYPE, "image/jpg")
            .build();
}

private StreamingOutput sendPicAsStream(String picUrl) {
    return output -> {
        try (InputStream is = (new URL(picUrl)).openStream()) {
            ByteStreams.copy(is, output);
        }
    };
}

using javax.ws.rs.core.Response and com.google.common.io.ByteStreams

$('#id-submit').click(function () {
    $("input").val(function(i,val) {
        return val.toUpperCase();
    });
});

FIDDLE

Using the so called f strings:

answer = True
myvar = f"the answer is {answer}"

Then if I do

print(myvar)

I will get:

the answer is True

I like f strings because one does not have to worry about the order in which the variables will appear in the printed text, which helps in case one has multiple variables to be printed as strings.

If you get the object after creation (for instance after "seasonal_decompose"), you can always access and edit the properties of the plot; for instance, changing the color of the first subplot from blue to black:

plt.axes[0].get_lines()[0].set_color('black')

To make changes to sudo from putty/bash:

• Type visudo and press enter.
• Navigate to the place you wish to edit using the up and down arrow keys.
• Press insert to go into editing mode.
• Make your changes - for example: user ALL=(ALL) ALL.
• Note - it matters whether you use tabs or spaces when making changes.
• Once your changes are done press esc to exit editing mode.
• Now type :wq to save and press enter.
• You should now be back at bash.
• Now you can press ctrl + D to exit the session if you wish.

Check the following example:

// First get your image
$imgPath = 'path-to-your-picture/image.jpg';
$img = base64_encode(file_get_contents($imgPath));
echo '<img width="100" height="100" src="data:image/jpg;base64,'. $img .'" />'

edit 2018: This is outdated, js and typescript now have for..of loops.
http://www.typescriptlang.org/docs/handbook/iterators-and-generators.html

The book "TypeScript Revealed" says

"You can iterate through the items in an array by using either for or for..in loops as demonstrated here:

// standard for loop
for (var i = 0; i < actors.length; i++)
{
  console.log(actors[i]);
}

// for..in loop
for (var actor in actors)
{
  console.log(actor);
}

"

Turns out, the second loop does not pass the actors in the loop. So would say this is plain wrong. Sadly it is as above, loops are untouched by typescript.

map and forEach often help me and are due to typescripts enhancements on function definitions more approachable, lke at the very moment:

this.notes = arr.map(state => new Note(state));

My wish list to TypeScript;

1. Generic collections
2. Iterators (IEnumerable, IEnumerator interfaces would be best)

Okay, finally figured out where I was remiss. I was under the mistaken notion that I should wrap each DAO method in a transaction. Terribly wrong! I've learned my lesson. I've hauled all the transaction code from all the DAO methods and have set up transactions strictly at the application/manager layer. This has totally solved all my problems. Data is properly lazy loaded as I need it, wrapped up and closed down once I do the commit.

Life is goodly... :)

I find db.serverCmdLineOpts() the most robust way to find actual path if you can connect to the server. The "parsed.storage.dbPath" contains the path your server is currently using and is available both when it's taken from the config or from the command line arguments.

Also in my case it was important to make sure that the config value reflects the actual value (i.e. config didn't change after the last restart), which isn't guaranteed by the solutions offered here.

db.serverCmdLineOpts()

Example output:

{
    "argv" : [ 
        // --
    ],
    "parsed" : {
        "config" : "/your-config",
        "storage" : {
            "dbPath" : "/your/actual/db/path",
            // --
        }
    },
    "ok" : 1.0
}

Your problem stems from reading from and writing to the same file. Rather than opening fileToSearch for writing, open an actual temporary file and then after you're done and have closed tempFile, use os.rename to move the new file over fileToSearch.

I was trying to use BrowserModule in a shared module (import and export). That was not allowed so instead I had to use the CommonModule instead and it worked.

This error occurs when you push the data from your local directory to your remote git repository by following git command: git push -u origin master

As local directory and git remote directory's files conflicted.

Solution :

After committing all files to staging follow below steps.

1. Fetch the files from the remote repository as its conflict with the local working directory.

   • git pull <remoter-url> <branch-name>

2. Commit the changes again.

   • git add -A
   • git commit -m ‘<comment>'

3. After committed merge files with both directory you can use

   • git push -u origin master

This will fix the issue. Thanks.

I generally store my macros in xlam add-ins separately from my workbooks so I wanted to open a workbook and then run a macro stored separately.

Since this required a VBS Script, I wanted to make it "portable" so I could use it by passing arguments. Here is the final script, which takes 3 arguments.

• Full Path to Workbook
• Macro Name
• [OPTIONAL] Path to separate workbook with Macro

I tested it like so:

"C:\Temp\runmacro.vbs" "C:\Temp\Book1.xlam" "Hello"

"C:\Temp\runmacro.vbs" "C:\Temp\Book1.xlsx" "Hello" "%AppData%\Microsoft\Excel\XLSTART\Book1.xlam"

runmacro.vbs:

Set args = Wscript.Arguments

ws = WScript.Arguments.Item(0)
macro = WScript.Arguments.Item(1)
If wscript.arguments.count > 2 Then
 macrowb= WScript.Arguments.Item(2)
End If

LaunchMacro

Sub LaunchMacro() 
  Dim xl
  Dim xlBook  

  Set xl = CreateObject("Excel.application")
  Set xlBook = xl.Workbooks.Open(ws, 0, True)
  If wscript.arguments.count > 2 Then
   Set macrowb= xl.Workbooks.Open(macrowb, 0, True)
  End If
  'xl.Application.Visible = True ' Show Excel Window
  xl.Application.run macro
  'xl.DisplayAlerts = False  ' suppress prompts and alert messages while a macro is running
  'xlBook.saved = True ' suppresses the Save Changes prompt when you close a workbook
  'xl.activewindow.close
  xl.Quit

End Sub
