Well this really depends on the compiler environment. gcc does not catch these. Visual Studio and the last Borland that I used did.

So the conclusion about crashes is that it depends on the quality of your development environment.

The C++ specification says that catch(...) must catch any exceptions, but it doesn't in all cases.

At least from what I tried.

You need to escape it with two backslashes

\\?

See this for more details:

http://www.trans4mind.com/personal_development/JavaScript/Regular%20Expressions%20Simple%20Usage.htm

This can also be achieved by Ctrl+WindowsBtn+Alt+L. This will be important to some people,because in some Virtual Machines, Ctrl+Alt+L can log you out.

you can create your own custom event by using diagnostics.Event log class. Open a windows application and on a button click do the following code.

System.Diagnostics.EventLog.CreateEventSource("ApplicationName", "MyNewLog");

"MyNewLog" means the name you want to give to your log in event viewer.

R defines a ~ (tilde) operator for use in formulas. Formulas have all sorts of uses, but perhaps the most common is for regression:

library(datasets)
lm( myFormula, data=iris)

help("~") or help("formula") will teach you more.

@Spacedman has covered the basics. Let's discuss how it works.

First, being an operator, note that it is essentially a shortcut to a function (with two arguments):

> `~`(lhs,rhs)
lhs ~ rhs
> lhs ~ rhs
lhs ~ rhs

That can be helpful to know for use in e.g. apply family commands.

Second, you can manipulate the formula as text:

oldform <- as.character(myFormula) # Get components
myFormula <- as.formula( paste( oldform[2], "Sepal.Length", sep="~" ) )

Third, you can manipulate it as a list:

myFormula[[2]]
myFormula[[3]]

Finally, there are some helpful tricks with formulae (see help("formula") for more):

myFormula <- Species ~ . 

For example, the version above is the same as the original version, since the dot means "all variables not yet used." This looks at the data.frame you use in your eventual model call, sees which variables exist in the data.frame but aren't explicitly mentioned in your formula, and replaces the dot with those missing variables.

One example, if you need to reference/join the same data set multiple times you can do so by defining a CTE. Therefore, it can be a form of code re-use.

An example of self referencing is recursion: Recursive Queries Using CTE

For exciting Microsoft definitions Taken from Books Online:

A CTE can be used to:

• Create a recursive query. For more information, see Recursive Queries Using Common Table Expressions.

• Substitute for a view when the general use of a view is not required; that is, you do not have to store the definition in metadata.

• Enable grouping by a column that is derived from a scalar subselect, or a function that is either not deterministic or has external access.

• Reference the resulting table multiple times in the same statement.

Only two Semicolons are allowed to be used in for loop.

1. Before first semicolon is the initialization part.
2. After first semicolon and before second semicolon is condition part (must result in boolean).
3. After second semicolon is variable manipulation part (increment/decrement part).

If you have do initialization of multiple variables or manipulation of multiple variables, you can achieve it by separating them with comma(,).

for(int i=0, j=5; i < 5; i++, j--)

NOTE: Multiple conditions separated by comma are NOT allowed.

for(int i=0, j=5; i < 5, j > 5; i++, j--) // This is NOT allowed.

I think all the answers are lacking something. I prefer using something like this

$('li.current_sub').prevUntil("li.par_cat").prev();

Saves you not adding :first inside the selector and is easier to read and understand. prevUntil() method has a better performance as well rather than using prevAll()

I had this same error in an MVC 4 application using Razor. In an attempt to clean up the web.config files, I removed the two webpages: configuration values:

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

Once I restored these configuration values, the pages would compile correctly and the errors regarding the .Partial() extension method disappeared.

session.abandon() will not remove the sessionID cookie from the browser. Therefore any new requests after this will take the same session ID. Hence, use Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", "")); after session.abandon().

You can use the ng-selected directive on the option elements. It takes expression that if truthy will set the selected property.

In this case:

<option ng-selected="data.unit == item.id" 
        ng-repeat="item in units" 
        ng-value="item.id">{{item.label}}</option>

Demo

angular.module("app",[]).controller("myCtrl",function($scope) {_x000D_
    $scope.units = [_x000D_
        {'id': 10, 'label': 'test1'},_x000D_
        {'id': 27, 'label': 'test2'},_x000D_
        {'id': 39, 'label': 'test3'},_x000D_
    ]_x000D_
_x000D_
        $scope.data = {_x000D_
        'id': 1,_x000D_
        'unit': 27_x000D_
        }_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
<div ng-app="app" ng-controller="myCtrl">_x000D_
    <select class="form-control" ng-change="unitChanged()" ng-model="data.unit">_x000D_
         <option ng-selected="data.unit == item.id" ng-repeat="item in units" ng-value="item.id">{{item.label}}</option>_x000D_
    </select>_x000D_
</div>

This works for me:

<input type='submit' name='self' value='This window' onclick='this.form.target="_self";' />

<input type='submit' name='blank' value='New window' onclick='this.form.target="_blank";' />

You can use .substring, which returns a potion of a string:

"abcdefghijklmnopq".substring(0, 8) === "abcdefgh"; // portion from index 0 to 8

Not completely entirely a direct answer to the original question, but relevant for the curious quickly trying to visually understand their cookie information storage planning without implementing a complex limiter algorithm, this string is 4096 ASCII character bytes:

"abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmn"

Using Blob as a source for an img:

template:

<img [src]="url">

component:

 public url : SafeResourceUrl;

 constructor(private http: HttpClient, private sanitizer: DomSanitizer) {
   this.getImage('/api/image.jpg').subscribe(x => this.url = x)
 }

 public getImage(url: string): Observable<SafeResourceUrl> {
   return this.http
     .get(url, { responseType: 'blob' })
     .pipe(
       map(x => {
         const urlToBlob = window.URL.createObjectURL(x) // get a URL for the blob
         return this.sanitizer.bypassSecurityTrustResourceUrl(urlToBlob); // tell Anuglar to trust this value
       }),
     );
 }

Further reference about trusting save values

In addition to pattern matching with 'like' keyword. You can also perform search by using fulltext feature as below;

SELECT * FROM clients WHERE MATCH (shipping_name, billing_name, email) AGAINST ('mary')

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

I would say:

#mybox{_x000D_
  background:green;  _x000D_
}_x000D_
_x000D_
#mybox:hover{_x000D_
  color:transparent;_x000D_
}

<div id="mybox">_x000D_
  This text will disappear on hover  _x000D_
</div>

This will hide text, but of course, it still contains the text, but it is a tricky way to hide the text (make in invisible), but it will work well

You want to put the ISNULL inside of the COUNT function, not outside:

Not GOOD: ISNULL(COUNT(field), 0)

GOOD: COUNT(ISNULL(field, 0))

I prefer using Hamcrest because it gives much better output in case of a failure

Assert.assertThat(listUnderTest, 
       IsIterableContainingInOrder.contains(expectedList.toArray()));

Instead of reporting

expected true, got false

it will report

expected List containing "1, 2, 3, ..." got list containing "4, 6, 2, ..."

IsIterableContainingInOrder.contain

Hamcrest

According to the Javadoc:

Creates a matcher for Iterables that matches when a single pass over the examined Iterable yields a series of items, each logically equal to the corresponding item in the specified items. For a positive match, the examined iterable must be of the same length as the number of specified items

So the listUnderTest must have the same number of elements and each element must match the expected values in order.

Test if the a variable is an array before getting the first element. When dynamically creating the array if it is set to null you get an error.

For Example:

if(is_array($array))
{
  reset($array);
  $first = key($array);
}

Add these two properties to your parent layout (ex: Linear Layout, Relative Layout)

android:focusable="true"
android:focusableInTouchMode="true" 

It will do the trick :)

"Upstream" would refer to the main repo that other people will be pulling from, e.g. your GitHub repo. The -u option automatically sets that upstream for you, linking your repo to a central one. That way, in the future, Git "knows" where you want to push to and where you want to pull from, so you can use git pull or git push without arguments. A little bit down, this article explains and demonstrates this concept.

That FireFox extension looks pretty nice. I've used SQLite Browser in the past and it did the job.

I also got a problem concerning a delimiter. the question was all about inputs of

1. enter your name.
2. enter your age.
3. enter your email.
4. enter your address.

The problem

1. I finished successfully with name, age, and email.
2. When I came up with the address of two words having a whitespace (Harnet street) I just got the first one "harnet".

The solution

I used the delimiter for my scanner and went out successful.

Example

 public static void main (String args[]){
     //Initialize the Scanner this way so that it delimits input using a new line character.
    Scanner s = new Scanner(System.in).useDelimiter("\n");
    System.out.println("Enter Your Name: ");
    String name = s.next();
    System.out.println("Enter Your Age: ");
    int age = s.nextInt();
    System.out.println("Enter Your E-mail: ");
    String email = s.next();
    System.out.println("Enter Your Address: ");
    String address = s.next();

    System.out.println("Name: "+name);
    System.out.println("Age: "+age);
    System.out.println("E-mail: "+email);
    System.out.println("Address: "+address);
}

I was having the same trouble with importing from Excel 2010 to Access, appending an "identical" table. Early on in the wizard it said not all my column names were valid, even though I checked them. It turns out that it saw an "empty" column with no column name. When I tried using the import wizard to create a new table instead, it worked. However, I noticed that it had added a blank column to the right of my data and called it "Field30". So I went back to the spreadsheet I was trying to import, selected the columns to the right of the data that I wanted, right-clicked and chose "clear contents." That did the trick and I was able to import the spreadsheet, appending it to my table.

The use of the deprecated new Buffer() constructor (i.E. as used by Yarn) can cause deprecation warnings. Therefore one should NOT use the deprecated/unsafe Buffer constructor.

According to the deprecation warning new Buffer() should be replaced with one of:

• Buffer.alloc()
• Buffer.allocUnsafe() or
• Buffer.from()

Another option in order to avoid this issue would be using the safe-buffer package instead.

You can also try (when using yarn..):

yarn global add yarn

as mentioned here: Link

Another suggestion from the comments (thx to gkiely): self-update

Note: self-update is not available. See policies for enforcing versions within a project

In order to update your version of Yarn, run

curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

Why not try fadeOut?

$(document).ready(function() {_x000D_
  $('#plsme').fadeOut(5000); // 5 seconds x 1000 milisec = 5000 milisec_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<div id='plsme'>Loading... Please Wait</div>

fadeOut (Javascript Pure):

How to make fadeOut effect with pure JavaScript

You can do it like... Just give the proper path of your json file...

<!doctype html>
<html>
    <head>
        <script type="text/javascript" src="abc.json"></script>
             <script type="text/javascript" >
                function load() {
                     var mydata = JSON.parse(data);
                     alert(mydata.length);

                     var div = document.getElementById('data');

                     for(var i = 0;i < mydata.length; i++)
                     {
                        div.innerHTML = div.innerHTML + "<p class='inner' id="+i+">"+ mydata[i].name +"</p>" + "<br>";
                     }
                 }
        </script>
    </head>
    <body onload="load()">
    <div id= "data">

    </div>
    </body>
</html>

Simply getting the data and appending it to a div... Initially printing the length in alert.

Here is my Json file: abc.json

data = '[{"name" : "Riyaz"},{"name" : "Javed"},{"name" : "Arun"},{"name" : "Sunil"},{"name" : "Rahul"},{"name" : "Anita"}]';

Try this solution: http://code.google.com/p/upload-at-click/

This should do it. You were missing a ) and you only need """ not 4 of them. Also you don't need a elif at the end.

ans=True
while ans:
    print("""
    1.Add a Student
    2.Delete a Student
    3.Look Up Student Record
    4.Exit/Quit
    """)
    ans=raw_input("What would you like to do? ")
    if ans=="1":
      print("\nStudent Added")
    elif ans=="2":
      print("\n Student Deleted")
    elif ans=="3":
      print("\n Student Record Found")
    elif ans=="4":
      print("\n Goodbye") 
      ans = None
    else:
       print("\n Not Valid Choice Try again")

Use SHOW VARIABLES:

show variables like 'version';

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

One way to get this error is to forget to use the 'new' keyword when instantiating your Date in javascript like this:

> d = Date();
'Tue Mar 15 2016 20:05:53 GMT-0400 (EDT)'
> typeof(d);
'string'
> d.getFullYear();
TypeError: undefined is not a function

Had you used the 'new' keyword, it would have looked like this:

> el@defiant $ node
> d = new Date();
Tue Mar 15 2016 20:08:58 GMT-0400 (EDT)
> typeof(d);
'object'
> d.getFullYear(0);
2016

Another way to get that error is to accidentally re-instantiate a variable in javascript between when you set it and when you use it, like this:

el@defiant $ node
> d = new Date();
Tue Mar 15 2016 20:12:13 GMT-0400 (EDT)
> d.getFullYear();
2016
> d = 57 + 23;
80
> d.getFullYear();
TypeError: undefined is not a function

Using $injector to call service methods in config

I had a similar issue and resolved it by using the $injector service as shown above. I tried injecting the service directly but ended up with a circular dependency on $http. The service displays a modal with the error and I am using ui-bootstrap modal which also has a dependency on $https.

    $httpProvider.interceptors.push(function($injector) {
    return {
        "responseError": function(response) {

            console.log("Error Response status: " + response.status);

            if (response.status === 0) {
                var myService= $injector.get("myService");
                myService.showError("An unexpected error occurred. Please refresh the page.")
            }
        }
    }

A dictionary probably isn't what you should be using in this case. A more full featured library would be a better alternative. Probably a real database. The easiest would be sqlite. You can keep the whole thing in memory by passing in the string ':memory:' instead of a filename.

If you do want to continue down this path, you can do it with the extra attributes in the key or the value. However a dictionary can't be the key to a another dictionary, but a tuple can. The docs explain what's allowable. It must be an immutable object, which includes strings, numbers and tuples that contain only strings and numbers (and more tuples containing only those types recursively...).

You could do your first example with d = {('apple', 'red') : 4}, but it'll be very hard to query for what you want. You'd need to do something like this:

#find all apples
apples = [d[key] for key in d.keys() if key[0] == 'apple']

#find all red items
red = [d[key] for key in d.keys() if key[1] == 'red']

#the red apple
redapples = d[('apple', 'red')]

Markdown Anchor supports the hashmark, so a link to an anchor in the page would simply be [Pookie](#pookie)

Generating the anchor is not actually supported in Gruber Markdown, but is in other implementations, such as Markdown Extra.

In Markdown Extra, the anchor ID is appended to a header or subhead with {#pookie}.

Github Flavored Markdown in Git repository pages (but not in Gists) automatically generates anchors with several markup tags on all headers (h1, h2, h3, etc.), including:

• id="user-content-HEADERTEXT"
• class="anchor"
• href="#HEADERTEXT"
• aria-hidden="true" (this is for an svg link icon that displays on mouseover)

Excluding the aria/svg icon, when one writes:

• # Header Title

Github generates:

• <h1><a id="user-content-header-title" class="anchor" href="#header-title">Header Title</a></h1>

Therefore, one need do nothing to create the header links, and can always link to them with:

• Link to the [Header Title](#header-title)

netstat -ano | findstr :3010

taskkill /F /PID

But it won't work for me

then I tried taskkill -PID <processorid> -F

Example:- taskkill -PID 33192 -F Here 33192 is the processorid and it works

In my case I was using XAMPP, and there was a log that told me the error. To find it, go to the XAMPP control panel, and click "Configure" for MySQL, then click on "Open Log."

The most current data of the log is at the bottom, and the log is organized by date, time, some number, and text in brackets that may say "Note" or "Error." One that says "Error" is likely causing the issue.

For me, my error was a tablespace that was causing an issue, so I deleted the database files at the given location.

Note: The tablespace files for your installation of XAMPP may be at a different location, but they were in /opt/lampp/var/mysql for me. I think that's typical of XAMPP on Debian-based distributions. Also, my instructions on what to click in the control panel to see the log may be a bit different for you because I'm running XAMPP on an Ubuntu-based distribution of Linux (Feren OS).

My two cents, escape the end of line to get the indents:

def foo():
    return "{}\n"\
           "freq: {}\n"\
           "temp: {}\n".format( time, freq, temp )

You can try this also to replace existing object

toDoTaskList = [
                {id:'abcd', name:'test'},
                {id:'abcdc', name:'test'},
                {id:'abcdtr', name:'test'}
              ];

newRecordToUpdate = {id:'abcdc', name:'xyz'};
this.toDoTaskList.map((todo, i) => {
         if (todo.id == newRecordToUpdate .id){
            this.toDoTaskList[i] = updatedVal;
          }
        });

When writing your own loop, as in the simulation (I assume), you need to call the update function which does what the mainloop does: updates the window with your changes, but you do it in your loop.

def task():
   # do something
   root.update()

while 1:
   task()  

These snippets all perform exactly the same thing:

element.on('click', function () { ... });
element.bind('click', function () { ... });
element.click(function () { ... });

However, they are very different from these, which all perform the same thing:

element.on('click', 'selector', function () { ... });
element.delegate('click', 'selector', function () { ... });
$('selector').live('click', function () { ... });

The second set of event handlers use event delegation and will work for dynamically added elements. Event handlers that use delegation are also much more performant. The first set will not work for dynamically added elements, and are much worse for performance.

jQuery's on() function does not introduce any new functionality that did not already exist, it is just an attempt to standardize event handling in jQuery (you no longer have to decide between live, bind, or delegate).

You don't need to use GROUP BY but using it won't change the outcome. Just add an ORDER BY line at the end to sort your results.

Most likely you should use CopyWebpackPlugin which was mentioned in kevlened answer. Alternativly for some kind of files like .html or .json you can also use raw-loader or json-loader. Install it via npm install -D raw-loader and then what you only need to do is to add another loader to our webpack.config.js file.

Like:

{
    test: /\.html/,
    loader: 'raw'
}

Note: Restart the webpack-dev-server for any config changes to take effect.

And now you can require html files using relative paths, this makes it much easier to move folders around.

template: require('./nav.html')  

Use a loop

for(var i = 0; i < obj.length; ++i){
   //do something with obj[i]
   for(var ind in obj[i]) {
        console.log(ind);
        for(var vals in obj[i][ind]){
            console.log(vals, obj[i][ind][vals]);
        }
   }
}

In memory usage and speed.

When you call jsonstr = json.dumps(mydata) it first creates a full copy of your data in memory and only then you file.write(jsonstr) it to disk. So this is a faster method but can be a problem if you have a big piece of data to save.

When you call json.dump(mydata, file) -- without 's', new memory is not used, as the data is dumped by chunks. But the whole process is about 2 times slower.

Source: I checked the source code of json.dump() and json.dumps() and also tested both the variants measuring the time with time.time() and watching the memory usage in htop.

Without wanting to give you the answer here is the logic.

You have 2 possible values in each digit. you have 9 of them.

like in base 10 where you have 10 different values by digit say you have 2 of them (which makes from 0 to 99) : 0 to 99 makes 100 numbers. if you do the calcul you have an exponential function

base^numberOfDigits:
10^2 = 100 ;
2^9 = 512

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

You have to tell the system what information to log and where to put the info. Logging is configured in the /etc/rsyslog.conf file, then restart rsyslog to load the new config. The default logging rules are usually in a /etc/rsyslog.d/50-default.conf file.

matejkramny's solution is a good start, but oversized images have a wrong ratio.

Here's my fork:

Demo: https://jsbin.com/lidebapomi/edit?html,css,output

HTML:

<div class="frame">
  <img src="foo"/>
</div>

CSS:

.frame {
    height: 160px; /* Can be anything */
    width: 160px; /* Can be anything */
    position: relative;
}
img {
    max-height: 100%;
    max-width: 100%;
    width: auto;
    height: auto;
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    margin: auto;
}

Instead of using existing utilities, you may try below conversion using boolean operation:

To upper case:

 char upperChar = 'l' & 0x5f

To lower case:

   char lowerChar = 'L' ^ 0x20

How it works:

Binary, hex and decimal table:

------------------------------------------
| Binary   |   Hexadecimal     | Decimal |
-----------------------------------------
| 1011111  |    0x5f           |  95     |
------------------------------------------
| 100000   |    0x20           |  32     |
------------------------------------------

Let's take an example of small l to L conversion:

The binary AND operation: (l & 0x5f)

l character has ASCII 108 and 01101100 is binary represenation.

   1101100
&  1011111
-----------
   1001100 = 76 in decimal which is **ASCII** code of L

Similarly the L to l conversion:

The binary XOR operation: (L ^ 0x20)

   1001100
^  0100000
-----------
   1101100 = 108 in decimal which is **ASCII** code of l

Is canny your own function? Do you use Canny from OpenCV inside it? If yes check if you feed suitable argument for Canny - first Canny argument should meet following criteria:

• type: <type 'numpy.ndarray'>
• dtype: dtype('uint8')
• being single channel or simplyfing: grayscale, that is 2D array, i.e. its shape should be 2-tuple of ints (tuple containing exactly 2 integers)

You can check it by printing respectively

type(variable_name)
variable_name.dtype
variable_name.shape

Replace variable_name with name of variable you feed as first argument to Canny.

If you can pick a reasonable maximum line length, you can seek to nearly the end of the file before you start reading.

myfile.seek(-max_line_length, os.SEEK_END)
line = myfile.readlines()[-1]

There is one slight difference: return code.

The thing is that unless shopt -o pipefail is set the return code of the piped command will be return code of the last one. And uniq always returns zero (success). Try examining exit code, and you'll see something like this (pipefail is not set here):

pavel@lonely ~ $ sort -u file_that_doesnt_exist ; echo $?
sort: open failed: file_that_doesnt_exist: No such file or directory
2
pavel@lonely ~ $ sort file_that_doesnt_exist | uniq ; echo $?
sort: open failed: file_that_doesnt_exist: No such file or directory
0

Other than this, the commands are equivalent.

For future Googlers i've a different approach to check if it's last element. It's similar to last lines in OP question.

This directly compares elements rather than just checking index numbers.

$yourset.each(function() {
    var $this = $(this);
    if($this[0] === $yourset.last()[0]) {
        //$this is the last one
    }
});

Edit: As of iOS 3.2, this functionality is built in. If you need to support pre-3.2, you can still use this solution.

I created a simple module that extends UILabel and handles loading .ttf files. I released it opensource under the Apache license and put it on github Here.

The important files are FontLabel.h and FontLabel.m.

It uses some of the code from Genericrich's answer.

Browse the source Here.

OR

• Copy your font file into resources

• Add a key to your Info.plist file called UIAppFonts. ("Fonts provided by application)

• Make this key an array

• For each font you have, enter the full name of your font file (including the extension) as items to the UIAppFonts array

• Save Info.plist

• Now in your application you can simply call [UIFont fontWithName:@"CustomFontName" size:15] to get the custom font to use with your UILabels and UITextViews, etc…

For More Information

I didn't find any of the mentioned options to be correct or work for me when I came to this page. They did give me ideas to test things out and I found that this worked for me.

dontGoToLink(e) {
  e.preventDefault();
 }

render() {
  return (<a href="test.com" onClick={this.dontGoToLink} />});
}

Building on the answer of JMax, use this formula for the dynamic named range to make the solution work for multiple rows:

=OFFSET(Sheet2!$A$1,MATCH(INDIRECT("Sheet1!"&ADDRESS(ROW(),COLUMN(),4))&"*",Sheet2!$A$1:$A$300,0)-1,0,COUNTA(Sheet2!$A:$A))

What's FAT?

FAT may sound like a strange name for a file system, but it's actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, offer support for FAT.

The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Filenames aren't case sensitive.

What About VFAT?

Perhaps you've also heard of a file system called VFAT. VFAT is an extension of the FAT file system and was introduced with Windows 95. VFAT maintains backward compatibility with FAT but relaxes the rules. For example, VFAT filenames can contain up to 255 characters, spaces, and multiple periods. Although VFAT preserves the case of filenames, it's not considered case sensitive.

When you create a long filename (longer than 8.3) with VFAT, the file system actually creates two different filenames. One is the actual long filename. This name is visible to Windows 95, Windows 98, and Windows NT (4.0 and later). The second filename is called an MS-DOS® alias. An MS-DOS alias is an abbreviated form of the long filename. The file system creates the MS-DOS alias by taking the first six characters of the long filename (not counting spaces), followed by the tilde [~] and a numeric trailer. For example, the filename Brien's Document.txt would have an alias of BRIEN'~1.txt.

An interesting side effect results from the way VFAT stores its long filenames. When you create a long filename with VFAT, it uses one directory entry for the MS-DOS alias and another entry for every 13 characters of the long filename. In theory, a single long filename could occupy up to 21 directory entries. The root directory has a limit of 512 files, but if you were to use the maximum length long filenames in the root directory, you could cut this limit to a mere 24 files. Therefore, you should use long filenames very sparingly in the root directory. Other directories aren't affected by this limit.

You may be wondering why we're discussing VFAT. The reason is it's becoming more common than FAT, but aside from the differences I mentioned above, VFAT has the same limitations. When you tell Windows NT to format a partition as FAT, it actually formats the partition as VFAT. The only time you'll have a true FAT partition under Windows NT 4.0 is when you use another operating system, such as MS-DOS, to format the partition.

FAT32

FAT32 is actually an extension of FAT and VFAT, first introduced with Windows 95 OEM Service Release 2 (OSR2). FAT32 greatly enhances the VFAT file system but it does have its drawbacks.

The greatest advantage to FAT32 is that it dramatically increases the amount of free hard disk space. To illustrate this point, consider that a FAT partition (also known as a FAT16 partition) allows only a certain number of clusters per partition. Therefore, as your partition size increases, the cluster size must also increase. For example, a 512-MB FAT partition has a cluster size of 8K, while a 2-GB partition has a cluster size of 32K.

This may not sound like a big deal until you consider that the FAT file system only works in single cluster increments. For example, on a 2-GB partition, a 1-byte file will occupy the entire cluster, thereby consuming 32K, or roughly 32,000 times the amount of space that the file should consume. This rule applies to every file on your hard disk, so you can see how much space can be wasted.

Converting a partition to FAT32 reduces the cluster size (and overcomes the 2-GB partition size limit). For partitions 8 GB and smaller, the cluster size is reduced to a mere 4K. As you can imagine, it's not uncommon to gain back hundreds of megabytes by converting a partition to FAT32, especially if the partition contains a lot of small files.

Note: This section of the quote/ article (1999) is out of date. Updated info quote below.

As I mentioned, FAT32 does have limitations. Unfortunately, it isn't compatible with any operating system other than Windows 98 and the OSR2 version of Windows 95. However, Windows 2000 will be able to read FAT32 partitions.

The other disadvantage is that your disk utilities and antivirus software must be FAT32-aware. Otherwise, they could interpret the new file structure as an error and try to correct it, thus destroying data in the process.

Finally, I should mention that converting to FAT32 is a one-way process. Once you've converted to FAT32, you can't convert the partition back to FAT16. Therefore, before converting to FAT32, you need to consider whether the computer will ever be used in a dual-boot environment. I should also point out that although other operating systems such as Windows NT can't directly read a FAT32 partition, they can read it across the network. Therefore, it's no problem to share information stored on a FAT32 partition with other computers on a network that run older operating systems.

Updated mentioned in comment by Doktor-J (assimilated to update out of date answer in case comment is ever lost):

I'd just like to point out that most modern operating systems (WinXP/Vista/7/8, MacOS X, most if not all Linux variants) can read FAT32, contrary to what the second-to-last paragraph suggests.

The original article was written in 1999, and being posted on a Microsoft website, probably wasn't concerned with non-Microsoft operating systems anyways.

The operating systems "excluded" by that paragraph are probably the original Windows 95, Windows NT 4.0, Windows 3.1, DOS, etc.

Okay, this might be late, but in Xcode 8 I have a solution:

if(textbox.stringValue.isEmpty) {
    // some code
} else {
    //some code
}

other = s or "some default value"

Ok, it must be clarified how the or operator works. It is a boolean operator, so it works in a boolean context. If the values are not boolean, they are converted to boolean for the purposes of the operator.

Note that the or operator does not return only True or False. Instead, it returns the first operand if the first operand evaluates to true, and it returns the second operand if the first operand evaluates to false.

In this case, the expression x or y returns x if it is True or evaluates to true when converted to boolean. Otherwise, it returns y. For most cases, this will serve for the very same purpose of C?'s null-coalescing operator, but keep in mind:

42    or "something"    # returns 42
0     or "something"    # returns "something"
None  or "something"    # returns "something"
False or "something"    # returns "something"
""    or "something"    # returns "something"

If you use your variable s to hold something that is either a reference to the instance of a class or None (as long as your class does not define members __nonzero__() and __len__()), it is secure to use the same semantics as the null-coalescing operator.

In fact, it may even be useful to have this side-effect of Python. Since you know what values evaluates to false, you can use this to trigger the default value without using None specifically (an error object, for example).

In some languages this behavior is referred to as the Elvis operator.

I created a small portable wrapper script called "xargsL" around "xargs" which addresses most of the problems.

Contrary to xargs, xargsL accepts one pathname per line. The pathnames may contain any character except (obviously) newline or NUL bytes.

No quoting is allowed or supported in the file list - your file names may contain all sorts of whitespace, backslashes, backticks, shell wildcard characters and the like - xargsL will process them as literal characters, no harm done.

As an added bonus feature, xargsL will not run the command once if there is no input!

Note the difference:

$ true | xargs echo no data
no data

$ true | xargsL echo no data # No output

Any arguments given to xargsL will be passed through to xargs.

Here is the "xargsL" POSIX shell script:

#! /bin/sh
# Line-based version of "xargs" (one pathname per line which may contain any
# amount of whitespace except for newlines) with the added bonus feature that
# it will not execute the command if the input file is empty.
#

set -e
trap 'test $? = 0 || echo "$0 failed!" >& 2' 0

if IFS= read -r first
then
        {
                printf '%s\n' "$first"
                cat
        } | sed 's/./\\&/g' | xargs ${1+"$@"}
fi

Put the script into some directory in your $PATH and don't forget to

$ chmod +x xargsL

the script there to make it executable.

I'm not sure about a way to do it directly with AngularJS but you could set the display to none for both welcome and login and animate the opacity with an directive once they are loaded.

I would do it some way like so. 2 Directives for fading in the content and fading it out when a link is clicked. The directive for fadeouts could simply animate a element with an unique ID or call a service which broadcasts the fadeout

Template:

<div class="tmplWrapper" onLoadFadeIn>
    <a href="somewhere/else" fadeOut>
</div>

Directives:

angular
  .directive('onLoadFadeIn', ['Fading', function('Fading') {
    return function(scope, element, attrs) {
      $(element).animate(...);
      scope.$on('fading', function() {
    $(element).animate(...);
      });
    }
  }])
  .directive('fadeOut', function() {
    return function(scope, element, attrs) {
      element.bind('fadeOut', function(e) {
    Fading.fadeOut(e.target);
  });
    }
  });

Service:

angular.factory('Fading', function() {
  var news;
  news.setActiveUnit = function() {
    $rootScope.$broadcast('fadeOut');
  };
  return news;
})

I just have put together this code quickly so there may be some bugs :)

It can also happen if you don't properly supply your list of parameters. Here's what I was doing:

java -jar [email protected] testing_subject file.txt test_send_emails.jar

Instead of the correct version:

java -jar test_send_emails.jar [email protected] testing_subject file.txt

Balanced tree is a tree whose height is of order of log(number of elements in the tree).

height = O(log(n))
O, as in asymptotic notation i.e. height should have same or lower asymptotic
growth rate than log(n)
n: number of elements in the tree

The definition given "a tree is balanced of each sub-tree is balanced and the height of the two sub-trees differ by at most one" is followed by AVL trees.

Since, AVL trees are balanced but not all balanced trees are AVL trees, balanced trees don't hold this definition and internal nodes can be unbalanced in them. However, AVL trees require all internal nodes to be balanced.

1. Include the Open Graph XML namespace extension to your HTML declaration

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:fb="http://ogp.me/ns/fb#">

2. Inside your <head></head> use the following meta tag to define the image you want to use

<meta property="og:image" content="fully_qualified_image_url_here" />

Read more about open graph protocol here.

After doing the above, use the Facebook "Object Debugger" if the image does not show up correctly. Also note the first time shared it still won't show up unless height and width are also specified, see Share on Facebook - Thumbnail not showing for the first time

Answered my own question:

IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by a colon (:).

So that's 39 characters max.

Use something like this:

page1.php

<?php
session_start();
$_SESSION['myValue']=3; // You can set the value however you like.
?>

Any other PHP page:

<?php
session_start();
echo $_SESSION['myValue'];
?>

A few notes to keep in mind though: You need to call session_start() BEFORE any output, HTML, echos - even whitespace.

You can keep changing the value in the session - but it will only be able to be used after the first page - meaning if you set it in page 1, you will not be able to use it until you get to another page or refresh the page.

The setting of the variable itself can be done in one of a number of ways:

$_SESSION['myValue']=1;
$_SESSION['myValue']=$var;
$_SESSION['myValue']=$_GET['YourFormElement'];

And if you want to check if the variable is set before getting a potential error, use something like this:

if(!empty($_SESSION['myValue'])
{
    echo $_SESSION['myValue'];
}
else
{
    echo "Session not set yet.";
}

char* str = "HELLO";
char c = str[1];

Keep in mind that arrays and strings in C begin indexing at 0 rather than 1, so "H" is str[0], "E" is str[1], the first "L" is str[2] and so on.

I find the solution in spring.io,like this:

    response.setHeader("Access-Control-Allow-Origin", "*");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "x-requested-with");

The "usual" solution is make a function that return an empty formGroup or a fullfilled formGroup

createFormGroup(data:any)
{
 return this.fb.group({
   user: [data?data.user:null],
   questioning: [data?data.questioning:null, Validators.required],
   questionType: [data?data.questionType, Validators.required],
   options: new FormArray([this.createArray(data?data.options:null])
})
}

//return an array of formGroup
createArray(data:any[]|null):FormGroup[]
{
   return data.map(x=>this.fb.group({
        ....
   })
}

then, in SUBSCRIBE, you call the function

this.qService.editQue([params["id"]]).subscribe(res => {
  this.editqueForm = this.createFormGroup(res);
});

be carefull!, your form must include an *ngIf to avoid initial error

<form *ngIf="editqueForm" [formGroup]="editqueForm">
   ....
</form>

If .attr() isn't working for you (especially when checking and unchecking boxes in succession), use .prop() instead of .attr().

In 3.1 there is a section already defined for "ConnectionStrings"

System.Configuration.ConnnectionStringSettings

Define:

  "ConnectionStrings": {
    "ConnectionString": "..."
  }

Register:

public void ConfigureServices(IServiceCollection services)
{
     services.Configure<ConnectionStringSettings>(Configuration.GetSection("ConnectionStrings"));
}

Inject:

public class ObjectModelContext : DbContext, IObjectModelContext
{

     private readonly ConnectionStringSettings ConnectionStringSettings;

    ...

     public ObjectModelContext(DbContextOptions<ObjectModelContext> options, IOptions<ConnectionStringSettings> setting) : base(options)
    {
          ConnectionStringSettings = setting.Value;
    }

    ...
}

Use:

   public static void ConfigureContext(DbContextOptionsBuilder optionsBuilder, ConnectionStringSettings connectionStringSettings)
    {
        if (optionsBuilder.IsConfigured == false)
        {
            optionsBuilder.UseLazyLoadingProxies()
                          .UseSqlServer(connectionStringSettings.ConnectionString);
        }
    }

I installed the 8.1 SDK's version:

https://developer.microsoft.com/en-us/windows/downloads/sdk-archive

It used 1GB (a little more) in the installation.

"Save link as" should help.

How malloc() and free() works depends on the runtime library used. Generally, malloc() allocates a heap (a block of memory) from the operating system. Each request to malloc() then allocates a small chunk of this memory be returning a pointer to the caller. The memory allocation routines will have to store some extra information about the block of memory allocated to be able to keep track of used and free memory on the heap. This information is often stored in a few bytes just before the pointer returned by malloc() and it can be a linked list of memory blocks.

By writing past the block of memory allocated by malloc() you will most likely destroy some of the book-keeping information of the next block which may be the remaining unused block of memory.

One place where you program may also crash is when copying too many characters into the buffer. If the extra characters are located outside the heap you may get an access violation as you are trying to write to non-existing memory.

You can always use Hash#key? to check if the key is present in a hash or not.

If not it will return you false

hash =  { one: 1, two:2 }

hash.key?(:one)
#=> true

hash.key?(:four)
#=> false

@jonrsharpe has an excellent explanation of what's going on. I thought I'd just show the difference in time when running each of the 3 options 10,000,000 times (enough for a slight difference to show).

Code used:

def a(x):
    if x != 'val':
        pass


def b(x):
    if not x == 'val':
        pass


def c(x):
    if x == 'val':
        pass
    else:
        pass


x = 1
for i in range(10000000):
    a(x)
    b(x)
    c(x)

And the cProfile profiler results:

So we can see that there is a very minute difference of ~0.7% between if not x == 'val': and if x != 'val':. Of these, if x != 'val': is the fastest.

However, most surprisingly, we can see that

if x == 'val':
        pass
    else:

is in fact the fastest, and beats if x != 'val': by ~0.3%. This isn't very readable, but I guess if you wanted a negligible performance improvement, one could go down this route.

Use Control.ControlCollection.Find.

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";

EDIT for asker:

Control[] tbxs = this.Controls.Find(txtbox_and_message[0,0], true);
if (tbxs != null && tbxs.Length > 0)
{
    tbxs[0].Text = "Found!";
}

I had a similar issue with zsh and nvm on Linux, I fixed it by adding nvm initialization script in ~/.profile and restart login session like this

export NVM_DIR="$HOME/.nvm" 
 [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm 
 [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

encodeURIComponent(JSON.stringify(object_to_be_serialised))

The language used by Facebook is PHP.

Also, do any other social networking sites use the same language?

The other one I know of is friendster.

just found an advance and most currently used method to set string in textView

textView.setText(String.valueOf(YourIntegerNumber));

If I have to change the contents of my options menu I perform it during the onMenuOpened(). This allows me to check the running state at the very moment that the user is accessing the menu.

public boolean onMenuOpened(int featureid, Menu menu)
    {
        menu.clear();
        if (!editable)
        {
            MenuItem itemAdd = menu.add(0, REASSIGN, Menu.NONE, context.getString(R.string.reassign));
            MenuItem itemMod = menu.add(1, EDIT, Menu.NONE, context.getString(R.string.modify));
            MenuItem itemDel = menu.add(2, DELETE, Menu.NONE, context.getString(R.string.delete));
            itemAdd.setShortcut('0', 'a');
            itemMod.setShortcut('1', 'm');
            itemDel.setShortcut('2', 'd');
        }
        else
        {
            MenuItem itemSave = menu.add(3, SAVE, Menu.NONE, context.getString(R.string.savechanges));
            itemSave.setShortcut('0', 'S');
        }


        return true;
    }

Every derived table (AKA sub-query) must indeed have an alias. I.e. each query in brackets must be given an alias (AS whatever), which can the be used to refer to it in the rest of the outer query.

SELECT ID FROM (
    SELECT ID, msisdn FROM (
        SELECT * FROM TT2
    ) AS T
) AS T

In your case, of course, the entire query could be replaced with:

SELECT ID FROM TT2

Simply go to the directory where the troubling file is, type touch * without quotes in the console, and you should be good.

Answer above is missing an example which might not be obvious (it wasn't to me).

Url could be broken down into parts

Hash can be found here (you can click it and will get the url from browser).

Hope this saves you some time.

As a memory fragmentation solution. I was getting out of memory exceptions while writing a lot of data into a memory stream (reading from a network stream). The data was written in 8K chunks. After reaching 128M there was exception even though there was a lot of memory available (but it was fragmented). Calling GC.Collect() solved the issue. I was able to handle over 1G after the fix.

In general, android:gravity="right" is different from android:layout_gravity="right".

The first one affects the position of the text itself within the View, so if you want it to be right-aligned, then layout_width= should be either "fill_parent" or "match_parent".

The second one affects the View's position inside its parent, in other words - aligning the object itself (edit box or text view) inside the parent view.

HTML CODE:

<div>
 <video class="center" src="vd/vd1.mp4" controls poster="dossierimage/imagex.jpg" width="600">?</video>
</div>

CSS CODE:

.center {
    margin-left: auto;
    margin-right: auto;
    display: block
}

Simply call getUrl() on URLConnection instance after calling getInputStream():

URLConnection con = new URL( url ).openConnection();
System.out.println( "orignal url: " + con.getURL() );
con.connect();
System.out.println( "connected url: " + con.getURL() );
InputStream is = con.getInputStream();
System.out.println( "redirected url: " + con.getURL() );
is.close();

If you need to know whether the redirection happened before actually getting it's contents, here is the sample code:

HttpURLConnection con = (HttpURLConnection)(new URL( url ).openConnection());
con.setInstanceFollowRedirects( false );
con.connect();
int responseCode = con.getResponseCode();
System.out.println( responseCode );
String location = con.getHeaderField( "Location" );
System.out.println( location );

You could use a div with a background image instead and this CSS3 property:

background-size: contain

You can check out an example on:

https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Scaling_background_images#contain

To quote Mozilla:

The contain value specifies that regardless of the size of the containing box, the background image should be scaled so that each side is as large as possible while not exceeding the length of the corresponding side of the container.

However, keep in mind that your image will be upscaled if the div is larger than your original image.

You can get free Virtual Machine and many more things online for 3 months provided by Microsoft Azure. I guess you need VPN for learning purpose. For that it would suffice.

Refer http://www.windowsazure.com/en-us/pricing/free-trial/

Or simply use the JFreechart library - http://www.jfree.org/jfreechart/ .

I would suggest the following for Java8+.

/**
 * Creates a File if the file does not exist, or returns a
 * reference to the File if it already exists.
 */
private File createOrRetrieve(final String target) throws IOException{

    final Path path = Paths.get(target);

    if(Files.notExists(path)){
        LOG.info("Target file \"" + target + "\" will be created.");
        return Files.createFile(Files.createDirectories(path)).toFile();
    }
    LOG.info("Target file \"" + target + "\" will be retrieved.");
    return path.toFile();
}

/**
 * Deletes the target if it exists then creates a new empty file.
 */
private File createOrReplaceFileAndDirectories(final String target) throws IOException{

    final Path path = Paths.get(target);
    // Create only if it does not exist already
    Files.walk(path)
        .filter(p -> Files.exists(p))
        .sorted(Comparator.reverseOrder())
        .peek(p -> LOG.info("Deleted existing file or directory \"" + p + "\"."))
        .forEach(p -> {
            try{
                Files.createFile(Files.createDirectories(p));
            }
            catch(IOException e){
                throw new IllegalStateException(e);
            }
        });

    LOG.info("Target file \"" + target + "\" will be created.");

    return Files.createFile(
        Files.createDirectories(path)
    ).toFile();
}

This approach may work for some kinds of classes (when the assignment operator behaves 'well'):

Foo::Foo()
{
    // do what every Foo is needing
    ...
}

Foo::Foo(char x)
{
    *this = Foo();

    // do the special things for a Foo with char
    ...
}

I just tested this and it works fine

var d = new Date(1441121836000);

The data object has a constructor which takes milliseconds as an argument.

FileReader r = new FileReader(file);

Use a file reader load the file and then write its contents to a string buffer.

example

The link above shows you an example of how to accomplish this. As other post to this answer say to load a file into memory you do not need write access as long as you do not plan on making changes to the actual file.

Since you actually stored the previous LAST_INSERT_ID() into the second table, you can get it from there:

INSERT INTO table1 (title,userid) VALUES ('test',1); 
INSERT INTO table2 (parentid,otherid,userid) VALUES (LAST_INSERT_ID(),4,1);
SELECT parentid FROM table2 WHERE id = LAST_INSERT_ID();

Here's a tutorial about ordering objects:

• The Java Tutorials - Collections - Object Ordering

Although I will give some examples, I would recommend to read it anyway.

There are various way to sort an ArrayList. If you want to define a natural (default) ordering, then you need to let Contact implement Comparable. Assuming that you want to sort by default on name, then do (nullchecks omitted for simplicity):

public class Contact implements Comparable<Contact> {

    private String name;
    private String phone;
    private Address address;

    @Override
    public int compareTo(Contact other) {
        return name.compareTo(other.name);
    }

    // Add/generate getters/setters and other boilerplate.
}

so that you can just do

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

Collections.sort(contacts);

If you want to define an external controllable ordering (which overrides the natural ordering), then you need to create a Comparator:

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

// Now sort by address instead of name (default).
Collections.sort(contacts, new Comparator<Contact>() {
    public int compare(Contact one, Contact other) {
        return one.getAddress().compareTo(other.getAddress());
    }
}); 

You can even define the Comparators in the Contact itself so that you can reuse them instead of recreating them everytime:

public class Contact {

    private String name;
    private String phone;
    private Address address;

    // ...

    public static Comparator<Contact> COMPARE_BY_PHONE = new Comparator<Contact>() {
        public int compare(Contact one, Contact other) {
            return one.phone.compareTo(other.phone);
        }
    };

    public static Comparator<Contact> COMPARE_BY_ADDRESS = new Comparator<Contact>() {
        public int compare(Contact one, Contact other) {
            return one.address.compareTo(other.address);
        }
    };

}

which can be used as follows:

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

// Sort by address.
Collections.sort(contacts, Contact.COMPARE_BY_ADDRESS);

// Sort later by phone.
Collections.sort(contacts, Contact.COMPARE_BY_PHONE);

And to cream the top off, you could consider to use a generic javabean comparator:

public class BeanComparator implements Comparator<Object> {

    private String getter;

    public BeanComparator(String field) {
        this.getter = "get" + field.substring(0, 1).toUpperCase() + field.substring(1);
    }

    public int compare(Object o1, Object o2) {
        try {
            if (o1 != null && o2 != null) {
                o1 = o1.getClass().getMethod(getter, new Class[0]).invoke(o1, new Object[0]);
                o2 = o2.getClass().getMethod(getter, new Class[0]).invoke(o2, new Object[0]);
            }
        } catch (Exception e) {
            // If this exception occurs, then it is usually a fault of the developer.
            throw new RuntimeException("Cannot compare " + o1 + " with " + o2 + " on " + getter, e);
        }

        return (o1 == null) ? -1 : ((o2 == null) ? 1 : ((Comparable<Object>) o1).compareTo(o2));
    }

}

which you can use as follows:

// Sort on "phone" field of the Contact bean.
Collections.sort(contacts, new BeanComparator("phone"));

(as you see in the code, possibly null fields are already covered to avoid NPE's during sort)

There is a built-in function in jQuery to check this (isNumeric), so try the following:

var phone = $("input#phone").val();
    if (phone !== "" && !$.isNumeric(phone)) {
  //Check if phone is numeric
  $("label#phone_error").show(); //Show error
  $("input#phone").focus(); //Focus on field
  return false;
}

The better option would be to just use the resource returned array as an array, meaning :

getResources().getStringArray(R.array.your_array)[position]

This is a shortcut approach of above mentioned approaches but does the work in the fashion you want. Otherwise android doesnt provides direct XML indexing for xml based arrays.

This is definitely not the best way to do this but, I got it done by doing something like following.

String imageName = "my_image.png";
String replace = imageName.replace('.','~');
String[] split = replace.split("~");

System.out.println("Image name : " + split[0]);
System.out.println("Image extension : " + split[1]);

Output,

Image name : my_image
Image extension : png

I'm using intelliJ 15 community edition and I'm able to right click a file and select 'add to .gitignore'

As we were already using jQuery for a graphical eye-candy feature we ended up using this. A code like

$(document).ready(function() {
    // any code goes here
    init();
});

did everything we wanted and cares about browser incompatibilities at its own.

An old question, I know, however, none of the answers here really do a good job of simply answer the question.

I just played around with php and the solution looks like this:

function myFunction($requiredArgument, $optionalArgument = "default"){
   echo $requiredArgument . $optionalArgument;
}

This function can do two things:

If its called with only the required parameter: myFunction("Hi") It will print "Hi default"

But if it is called with the optional parameter: myFunction("Hi","me") It will print "Hi me";

I hope this helps anyone who is looking for this down the road.

Thanks @Clint for the great answer:

Just wanted to highlight how easy it was to solve this using the Expando Object:

    var dynamicObject = new ExpandoObject() as IDictionary<string, Object>;
    foreach (var property in properties) {
        dynamicObject.Add(property.Key,property.Value);
    }

A combination of the regex and SimpleDateFormat is the right answer i believe. SimpleDateFormat does not catch exception if the individual components are invalid meaning, Format Defined: yyyy-mm-dd input: 201-0-12 No exception will be thrown.This case should have been handled. But with the regex as suggested by Sok Pomaranczowy and Baby will take care of this particular case.

here's a solution that can compare more than two dicts:

def diff_dict(dicts, default=None):
    diff_dict = {}
    # add 'list()' around 'd.keys()' for python 3 compatibility
    for k in set(sum([d.keys() for d in dicts], [])):
        # we can just use "values = [d.get(k, default) ..." below if 
        # we don't care that d1[k]=default and d2[k]=missing will
        # be treated as equal
        if any(k not in d for d in dicts):
            diff_dict[k] = [d.get(k, default) for d in dicts]
        else:
            values = [d[k] for d in dicts]
            if any(v != values[0] for v in values):
                diff_dict[k] = values
    return diff_dict

usage example:

import matplotlib.pyplot as plt
diff_dict([plt.rcParams, plt.rcParamsDefault, plt.matplotlib.rcParamsOrig])

One workaround I had for this was to iterate over the sectors(which at the time you could do...I haven't tested that recently).

You wind up getting blocked eventually when you do it that way though, since YQL gets throttled per day.

Use the CSV API whenever possible to avoid this.

I suggest, never delete data. Don't say if the tables is longer than 1000 truncate the end of the table. There needs to be real business logic in your plan like how long has this user been inactive. For example, if it is longer than 1 year then put them in a different table. You would have this happen weekly or monthly in a maintenance script in the middle of a slow time.

When you run into to many rows in your table then you should start sharding the tables or partitioning and put old data in old tables by year such as users_2011_jan, users_2011_feb or use numbers for the month. Then change your programming to work with this model. Maybe make a new table with less information to summarize the data in less columns and then only refer to the bigger partitioned tables when you need more information such as when the user is viewing their profile. All of this should be considered very carefully so in the future it isn't too expensive to re-factor. You could also put only the users which comes to your site all the time in one table and the users that never come in an archived set of tables.

In dplyr you may use n_distinct to "count the number of unique values":

library(dplyr)
myvec %>%
  group_by(name) %>%
  summarise(n_distinct(order_no))

Use for...in loop:

for (var key in obj) {
   console.log(' name=' + key + ' value=' + obj[key]);

   // do some more stuff with obj[key]
}

It looks OK apart from the space in your ID attribute, which is not valid, and the fact that you're replacing the value of your input before checking the selection.

function textbox()_x000D_
{_x000D_
        var ctl = document.getElementById('Javascript_example');_x000D_
        var startPos = ctl.selectionStart;_x000D_
        var endPos = ctl.selectionEnd;_x000D_
        alert(startPos + ", " + endPos);_x000D_
}

<input id="Javascript_example" name="one" type="text" value="Javascript example" onclick="textbox()">

Also, if you're supporting IE <= 8 you need to be aware that those browsers do not support selectionStart and selectionEnd.

Failure [INSTALL_FAILED_OLDER_SDK]

For Sumsung note3 I just edit the AndroidManifest.xml file and add the following code:

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17"/>

Here's my solution which I derived from other posts during my own search.

This allows you to send the pp and jj output to a file as needed.

require "pp"
require "json"

class File
  def pp(*objs)
    objs.each {|obj|
      PP.pp(obj, self)
    }
    objs.size <= 1 ? objs.first : objs
  end
  def jj(*objs)
    objs.each {|obj|
      obj = JSON.parse(obj.to_json)
      self.puts JSON.pretty_generate(obj)
    }
    objs.size <= 1 ? objs.first : objs
  end
end

test_object = { :name => { first: "Christopher", last: "Mullins" }, :grades => [ "English" => "B+", "Algebra" => "A+" ] }

test_json_object = JSON.parse(test_object.to_json)

File.open("log/object_dump.txt", "w") do |file|
  file.pp(test_object)
end

File.open("log/json_dump.txt", "w") do |file|
  file.jj(test_json_object)
end

I wanna Disable an Input Field on a form and when i submit the form the values from the disabled form is not submitted.

Use Case: i am trying to get Lat Lng from Google Map and wanna Display it.. but dont want the user to edit it.

You can use the readonly property in your input field

<input type="text" readonly="readonly" />

In case you are working in the latest toolbar in android studio then here is the smallest solution To change the toolbar options menu color, add this to your toolbar element

 app:popupTheme="@style/MyDarkToolbarStyle"

Then in your styles.xml define the popup menu style

<style name="MyDarkToolbarStyle" parent="ThemeOverlay.AppCompat.Light"> <item name="android:colorBackground">@color/mtrl_white_100</item> <item name="android:textColor">@color/mtrl_light_blue_900</item> </style>

Note that you need to use colorBackground not background. The latter would be applied to everything (the menu itself and each menu item), the former applies only to the popup menu.

This steps are used in spring boot with self signed ssl certificate implementation

if SSL turns off then HTTPS call will be worked as expected.

https://localhost:8443/test/hello

These are the steps we have to follow,

1. Generate self signed ssl certificate

keytool -genkeypair -alias tomcat -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore keystore.p12 -validity 3650

after key generation has done then copy that file in to the resource foder in your project

2. add key store properties in applicaiton.properties

server.port: 8443
server.ssl.key-store:classpath:keystore.p12
server.ssl.key-store-password: test123
server.ssl.keyStoreType: PKCS12
server.ssl.keyAlias: tomcat

3. change your postman ssl verification settings to turn OFF

now verify the url: https://localhost:8443/test/hello

as suggested here solving the famous LazyInitializationException is one of the following methods:

(1) Use Hibernate.initialize

Hibernate.initialize(topics.getComments());

(2) Use JOIN FETCH

You can use the JOIN FETCH syntax in your JPQL to explicitly fetch the child collection out. This is somehow like EAGER fetching.

(3) Use OpenSessionInViewFilter

LazyInitializationException often occurs in the view layer. If you use Spring framework, you can use OpenSessionInViewFilter. However, I do not suggest you to do so. It may leads to a performance issue if not used correctly.

What I ended up doing was to keep the file within my vagrant directory (automatically mounted as /vagrant/) and copy it over with a shell provisioner:

command = "cp #{File.join('/vagrant/', path_within_repo)} #{remote_file}"
config.vm.provision :shell, :inline => command

Since Express 4.0, there's a dedicated sendStatus function:

res.sendStatus(404);

If you're using an earlier version of Express, use the status function instead.

res.status(404).send('Not found');

SELECT  [ReportId], 
        SUBSTRING(d.EmailList,1, LEN(d.EmailList) - 1) EmailList
FROM
        (
            SELECT DISTINCT [ReportId]
            FROM Table1
        ) a
        CROSS APPLY
        (
            SELECT [Email] + ', ' 
            FROM Table1 AS B 
            WHERE A.[ReportId] = B.[ReportId]
            FOR XML PATH('')
        ) D (EmailList) 

SQLFiddle Demo

Well, the first interpretation is correct. However, your reasoning about the "signed semantics" in this context is wrong.

Again, your first interpretation is correct. Unsigned arithmetic follow the rules of modulo arithmetic, meaning that 0x0000 - 0x0001 evaluates to 0xFFFF for 32-bit unsigned types.

However, the second interpretation (the one based on "signed semantics") is also required to produce the same result. I.e. even if you evaluate 0 - 1 in the domain of signed type and obtain -1 as the intermediate result, this -1 is still required to produce 0xFFFF when later it gets converted to unsigned type. Even if some platform uses an exotic representation for signed integers (1's complement, signed magnitude), this platform is still required to apply rules of modulo arithmetic when converting signed integer values to unsigned ones.

For example, this evaluation

signed int a = 0, b = 1;
unsigned int c = a - b;

is still guaranteed to produce UINT_MAX in c, even if the platform is using an exotic representation for signed integers.

Use:

/*/ITEM[starts-with(REVENUE_YEAR,'2552')]/REGION

Note: Unless your host language can't handle element instance as result, do not use text nodes specially in mixed content data model. Do not start expressions with // operator when the schema is well known.

For Mac users in the 17.06.0-ce-mac19 version you can simply move the Disk Image location from the user interface in the preferences option Just change the location of the disk image and it will work (by clicking Move disk Image) and restarting the docker. Using this approach I was able to use my external hardisk for storing docker images.

A slightly faster option than using the already mentioned use of the Join() method is the Concat() method. It doesn't require an empty delimiter parameter as Join() does. Example:

string[] test = new string[2];
test[0] = "Hello ";
test[1] = "World!";

string result = String.Concat(test);

hence it is likely faster.

Check out WinObjC:

https://github.com/Microsoft/WinObjC

It's an official, open-source project by Microsoft that integrates with Visual Studio + Windows.

This is not a compiler error: the error is coming from the linker. After compilation, the linker will merge the object files resulting from the compilation of each of your translation units (.cpp files).

The linker finds out that you have the same symbol defined multiple times in different translation units, and complains about it (it is a violation of the One Definition Rule).

The reason is most certainly that main.cpp includes client.cpp, and both these files are individually processed by the compiler to produce two separate object files. Therefore, all the symbols defined in the client.cpp translation unit will be defined also in the main.cpp translation unit. This is one of the reasons why you do not usually #include .cpp files.

Put the definition of your class in a separate client.hpp file which does not contain also the definitions of the member functions of that class; then, let client.cpp and main.cpp include that file (I mean #include). Finally, leave in client.cpp the definitions of your class's member functions.

client.h

#ifndef SOCKET_CLIENT_CLASS
#define SOCKET_CLIENT_CLASS
#ifndef BOOST_ASIO_HPP
#include <boost/asio.hpp>
#endif

class SocketClient // Or whatever the name is...
{

// ...

    bool read(int, char*); // Or whatever the name is...

//  ...
};

#endif

client.cpp

#include "Client.h"

// ...

bool SocketClient::read(int, char*)
{
    // Implementation  goes here...
}

// ... (add the definitions for all other member functions)

main.h

#include <iostream>
#include <string>
#include <sstream>
#include <boost/asio.hpp>
#include <boost/thread/thread.hpp>
#include "client.h"
//              ^^ Notice this!

main.cpp

#include "main.h"

I had the same problem. Just Install the exact bit of java as of your computer. If your PC is 64 bit then install 64 bit java. If it is 32 bit then vice versa :)

When you use scp you have to tell the host name and ip address from where you want to copy the file. For instance, if you are at the remote host and you want to transfer the file to your pc you may use something like this:

scp -P[portnumber] myfile_at_remote_host [user]@[your_ip_address]:/your/path/

Example:

scp -P22 table [email protected]:/home/me/Desktop/

On the other hand, if you are at your are actually on your machine you may use something like this:

scp -P[portnumber] [remote_login]@[remote's_ip_address]:/remote/path/myfile_at_remote_host /your/path/

Example:

scp -P22 [fake_user]@222.222.222.222:/remote/path/table /home/me/Desktop/

There are many answers and all are correct as well. But unfortunately none of them have a clear explanation.

The following works for a non-primary key mapping as well.

Let's say we have parent table A with column 1 and another table, B, with column 2 which references column 1:

@ManyToOne
@JoinColumn(name = "TableBColumn", referencedColumnName = "TableAColumn")
private TableA session_UserName;

@ManyToOne
@JoinColumn(name = "bok_aut_id", referencedColumnName = "aut_id")
private Author bok_aut_id;

All the above answers are correct. Just providing with your dataset to find perfect divisor:

#include <stdio.h>

int main() 
{

int arr[7] = {3,5,7,8,9,17,19};
int j = 51;
int i = 0;

for (i=0 ; i < 7; i++) {
    if (j % arr[i] == 0)
        printf("%d is the perfect divisor of %d\n", arr[i], j);
}

return 0;
}

You can specify ord to get the L1 norm. To avoid zero division I use eps, but that's maybe not great.

def normalize(v):
    norm=np.linalg.norm(v, ord=1)
    if norm==0:
        norm=np.finfo(v.dtype).eps
    return v/norm

In my case it was happening because I had not typed a variable.

So I created the Search interface

export interface Search {
  term: string;
  ...
}

I changed that

searchList = [];

for that and it worked

searchList: Search[];

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

If you use instanceof, making your equals implementation final will preserve the symmetry contract of the method: x.equals(y) == y.equals(x). If final seems restrictive, carefully examine your notion of object equivalence to make sure that your overriding implementations fully maintain the contract established by the Object class.

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

-Right click on either axis

-Click "Select Data..."

-Then Press the "Edit" button

-Copy the "Series X values" to the "Series Y values" and vise versa finally hit ok

I found this answer on this youtube video https://www.youtube.com/watch?v=xLKIWWIWltE

A big difference is if you are displaying arrays. Especially ones with NIL. For example:

print [nil, 1, 2]

gives

[nil, 1, 2]

but

puts [nil, 1, 2]

gives

1
2

Note, no appearing nil item (just a blank line) and each item on a different line.

You will either need LESS or SASS for the same..

But here is another alternative which I believe will work out in CSS3..

http://css3.bradshawenterprises.com/blog/css-variables/

Example :

 :root {
    -webkit-var-beautifulColor: rgba(255,40,100, 0.8);
    -moz-var-beautifulColor: rgba(255,40,100, 0.8);
    -ms-var-beautifulColor: rgba(255,40,100, 0.8);
    -o-var-beautifulColor: rgba(255,40,100, 0.8);
    var-beautifulColor: rgba(255,40,100, 0.8);
 }
  .example1 h1 {
    color: -webkit-var(beautifulColor);
    color: -moz-var(beautifulColor);
    color: -ms-var(beautifulColor);
    color: -o-var(beautifulColor);
    color: var(beautifulColor);
 }

Check this out:

db.collection.find().pretty()

If you are writing in C++ -- it is a way better to use data structures from standard library such as vector.

C-style arrays are very error-prone, and should be avoided whenever possible.

angular.module('formComponents', [])
  .directive('formInput', function() {
    return {
        restrict: 'E',
        compile: function(element, attrs) {
            var type = attrs.type || 'text';
            var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
            var htmlText = '<div class="control-group">' +
                '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                    '<div class="controls">' +
                    '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                    '</div>' +
                '</div>';
            element.replaceWith(htmlText);
        }
    };
})

This is the coffescript version:

setTimeout ->
 $(".alert-dismissable").fadeTo(500, 0).slideUp(500, -> $(this.remove()))
,5000

I also got this error with apache mod-mono. It looks like the documentation page for webservice is not implemented yet in linux. But the webservice is working despite this error. You should see it by adding ?WSDL at the end of url, i.e http://localhost/WebService1.asmx?WSDL

To refresh the whole page, but it works normally:

Response.Redirect(url,bool) 

UPDATE:

Like @scottyseus said in the comments, starting from Maven Surefire 2.22.0 the following is sufficient:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.1</version>
</plugin>

When using JUnit 5, i ran into the same problem. Maven Surefire needs a plugin to run JUnit 5 tests. Add this to our pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>

There's this way too (new to EcmaScript5):

dictionary.data.forEach(function(item){
    console.log(item.name + ' ' + item.id);
});

Same approach for images

Generally speaking, using setState inside useEffect will create an infinite loop that most likely you don't want to cause. There are a couple of exceptions to that rule which I will get into later.

useEffect is called after each render and when setState is used inside of it, it will cause the component to re-render which will call useEffect and so on and so on.

One of the popular cases that using useState inside of useEffect will not cause an infinite loop is when you pass an empty array as a second argument to useEffect like useEffect(() => {....}, []) which means that the effect function should be called once: after the first mount/render only. This is used widely when you're doing data fetching in a component and you want to save the request data in the component's state.

There are a lot of dependencies of anaconda that have changed over the past years and won't work if you used them now. Some of the answers need serious updation.

I found this command did the job for me :

conda install -c conda-forge xgboost

You may also want to look at the official documentation of anaconda for xgboost:

You can accomplish this with jquery.

Place this code in index.html

<html>

    integrity="sha256-2Kok7MbOyxpgUVvAk/HJ2jigOSYS2auK4Pfzbm7uH60="
    crossorigin="anonymous">
</script>
<script> 
$(function(){
  $("#header").load("header.html"); 
  $("#footer").load("footer.html"); 
});
</script> 
</head>
<body>
<div id="header"></div>
<!--Remaining section-->
<div id="footer"></div>
</body>
</html>

and put this code in header.html and footer.html, at the same location as index.html

<a href="http://www.google.com">click here for google</a>

Now, when you visit index.html, you should be able to click the link tags.

if you don't have a good copy of your php5.ini file in your home directory (a predicament that I recently found myself in), you'll need to follow a little multi-step process to make your changes.

1. Create a little code snippet to look at the output of the phpinfo() call. This is simple, and there are multiple web-sites that describe this process.

2. Examine the output of phpinfo() for the row which contains Configuration File (php.ini) Path. Mine was in /usr/local/lib, but your's may be a different path (depends on hosting level purchased).

3. GoDaddy will NOT simply copy this file into your home directory for you --as silly as that sounds! But, you can write a little php program to copy this php.ini file into your home directory. The guy at https://www.jabari-holder.com/blog/how-to-get-godaddys-php5-ini-file/ has a drop-box with this code snippet, if you care to use it. Just take care to modify two things:

   • a. change the path you read 'from' to match the path you uncovered in Step 2.

   • b. change the output file-name to something of your choosing. You're going to re-name this file in a later step anyway. Let's call our copied file Foo.ini (but it can be anything).

4. Rename Foo.ini to .user.ini (for most GoDaddy account types).

df.where(df.col("friend_id").isNull)

Try Activity#finish(). This is more or less what the back button does by default.

This worked for me

let exampleArray = [1, 2, 3, 4, 5];
let exampleToString = exampleArray.toString(); //convert to toString
let query = `Select * from table_name where column_name in (${exampleToString})`; //Execute the query to get response

I have got the same problem, then after an hour of effort I got to know that the array should not be directly accessed in the query. So I then found that the data should be sent in the paranthesis it self, then again I have converted that array to string using toString method in js. So I have worked by executing the above query and got my expected result

Ugh, this is an old problem, something that still pops up in Visual Studio once in a while. It's bitten me a couple of times and I've lost hours restarting and fighting with VS. I'm sure it's been discussed here on SO more than once. It's also been talked about on the MSDN forums. There isn't an actual solution, but there are a couple of workarounds. Start researching here.

What's happening is that VS is acquiring a lock on a file and then not releasing it. Ironically, that lock prevents VS itself from deleting the file so that it can recreate it when you rebuild the application. The only apparent solution is to close and restart VS so that it will release the lock on the file.

My original workaround was opening up the bin/Debug folder and renaming the executable. You can't delete it if it's locked, but you can rename it. So you can just add a number to the end or something, which allows you to keep working without having to close all of your windows and wait for VS to restart. Some people have even automated this using a pre-build event to append a random string to the end of the old output filename. Yes, this is a giant hack, but this problem gets so frustrating and debilitating that you'll do anything.

I've later learned, after a bit more experimentation, that the problem seems to only crop up when you build the project with one of the designers open. So, the solution that has worked for me long term and prevented me from ever dealing with one of those silly errors again is making sure that I always close all designer windows before building a WinForms project. Yes, this too is somewhat inconvenient, but it sure beats the pants off having to restart VS twice an hour or more.

I assume this applies to WPF, too, although I don't use it and haven't personally experienced the problem there.

I also haven't yet tried reproducing it on VS 2012 RC. I don't know if it's been fixed there yet or not. But my experience so far has been that it still manages to pop up even after Microsoft has claimed to have fixed it. It's still there in VS 2010 SP1. I'm not saying their programmers are idiots who don't know what they're doing, of course. I figure there are just multiple causes for the bug and/or that it's very difficult to reproduce reliably in a laboratory. That's the same reason I haven't personally filed any bug reports on it (although I've +1'ed other peoples), because I can't seem to reliably reproduce it, rather like the Abominable Snowman.

Just select all of the files you want to compare, then open the context menu (Right-Click on the file) and choose Compare With, Then select each other..

Though the question is for button, but if anyone wants to refresh the page using <a>, you can simply do

<a href="./">Reload</a>

Using environment variable is sometimes more convenient when you do not control the build scripts / process.

For C includes use C_INCLUDE_PATH.

For C++ includes use CPLUS_INCLUDE_PATH.

See this link for other gcc environment variables.

Example usage in MacOS / Linux

# `pip install` will automatically run `gcc` using parameters
# specified in the `asyncpg` package (that I do not control)

C_INCLUDE_PATH=/home/scott/.pyenv/versions/3.7.9/include/python3.7m pip install asyncpg

Example usage in Windows

set C_INCLUDE_PATH="C:\Users\Scott\.pyenv\versions\3.7.9\include\python3.7m"

pip install asyncpg

# clear the environment variable so it doesn't affect other builds
set C_INCLUDE_PATH=

Another alternative which is similar to the accepted answer by @BenBolker is redefining the coordinates of the existing plot when adding a second set of points.

Here is a minimal example.

Data:

x  <- 1:10
y1 <- rnorm(10, 100, 20)
y2 <- rnorm(10, 1, 1)

Plot:

par(mar=c(5,5,5,5)+0.1, las=1)

plot.new()
plot.window(xlim=range(x), ylim=range(y1))
points(x, y1, col="red", pch=19)
axis(1)
axis(2, col.axis="red")
box()

plot.window(xlim=range(x), ylim=range(y2))
points(x, y2, col="limegreen", pch=19)
axis(4, col.axis="limegreen")

For Swift:

override func viewDidLoad() {
    super.viewDidLoad()
    tableView.tableFooterView = UIView()  // it's just 1 line, awesome!
}

Regarding existing answers, note that signal handling is platform dependent. Win32 for example handles far fewer signals than POSIX operating systems; see here. While SIGINT is declared in signals.h on Win32, see the note in the documentation that explains that it will not do what you might expect.

Try this:

HTML:

<div id="container">
    <div id="content">
        // Content here
    </div>
</div>

CSS:

#container{
    height: 100%;
    width: 100%;
    overflow: hidden;
}

#content{
    width: 100%;
    height: 99%;
    overflow: auto;
    padding-right: 15px;
}

html, body{
    height: 99%;
    overflow:hidden;
}

JSFiddle Demo

Tested on FF and Safari.

Open the CSV file with a decent text editor like Notepad++ and add the following text in the first line:

sep=,

Now open it with excel again.

This will set the separator as a comma, or you can change it to whatever you need.

This worked for me.

Directive:

modulename.directive('passwordCheck', function () {

    return {
        restrict: 'A', // only activate on element attribute
        require: '?ngModel', // get a hold of NgModelController
        link: function (scope, elem, attrs, ngModel) {
            if (!ngModel) return; // do nothing if no ng-model

            var Value = null;

            // watch own value and re-validate on change
            scope.$watch(attrs.ngModel, function (val) {
                Value = val;


                validate();
            });

            // observe the other value and re-validate on change
            attrs.$observe('passwordCheck', function () {
                validate();
            });

            var validate = function () {

                // values
                var val1 = Value;
                var val2 = attrs.passwordCheck;

                // set validity

                if (val1 != '' && val1 != undefined) {
                    ngModel.$setValidity('passwordCheck', val1 == val2);

                }

                else {
                    ngModel.$setValidity('passwordCheck', true);
                }
            };
        }
    }
});

ng-show="resetpasswordform.confirmpassword.$error.passwordCheck && submitted" Password does not match

My problem was that tomcat 8 and higher are not compatible with java 6. Changing to java 7 solved it.

You are actually encouraged to use the inflate method of your generated Binding and not the DataBindingUtil:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    MainFragmentBinding binding = MainFragmentBinding.inflate(inflater, container, false);
    //set variables in Binding
    return binding.getRoot();
}

Docs for DataBindingUtil.inflate():

Use this version only if layoutId is unknown in advance. Otherwise, use the generated Binding's inflate method to ensure type-safe inflation.

You can also try find() method. It determines if string str occurs in string, or in a substring of string.

str1 = "please help me out so that I could solve this"
str2 = "please help me out"

if (str1.find(str2)>=0):
  print("True")
else:
  print ("False")

Well, you have some options.

You could configure sudo to not prompt for a password. This is not recommended, due to the security risks.

You could write an expect script to read the password and supply it to sudo when required, but that's clunky and fragile.

I would recommend designing the script to run as root and drop its privileges whenever they're not needed. Simply have it sudo -u someotheruser command for the commands that don't require root.

(If they have to run specifically as the user invoking the script, then you could have the script save the uid and invoke a second script via sudo with the id as an argument, so it knows who to su to..)

In my case, I manually delete the app-debug.apk file and run it again.

document.getElementsByName("myInput")[0].value;

The reason why you get your error is because a "1 by n" matrix is different from an array of length n.

I recommend using hstack() and vstack() instead. Like this:

import numpy as np
a = np.arange(32).reshape(4,8) # 4 rows 8 columns matrix.
b = a[:,-1:]                    # last column of that matrix.

result = np.hstack((a,b))       # stack them horizontally like this:
#array([[ 0,  1,  2,  3,  4,  5,  6,  7,  7],
#       [ 8,  9, 10, 11, 12, 13, 14, 15, 15],
#       [16, 17, 18, 19, 20, 21, 22, 23, 23],
#       [24, 25, 26, 27, 28, 29, 30, 31, 31]])

Notice the repeated "7, 15, 23, 31" column. Also, notice that I used a[:,-1:] instead of a[:,-1]. My version generates a column:

array([[7],
       [15],
       [23],
       [31]])

Instead of a row array([7,15,23,31])

Edit: append() is much slower. Read this answer.

I disagree with the selected answer, and as davidxxx correctly pointed out, getReference does not provide such behaviour of dynamic updations without select. I asked a question concerning the validity of this answer, see here - cannot update without issuing select on using setter after getReference() of hibernate JPA.

I quite honestly haven't seen anybody who's actually used that functionality. ANYWHERE. And i don't understand why it's so upvoted.

Now first of all, no matter what you call on a hibernate proxy object, a setter or a getter, an SQL is fired and the object is loaded.

But then i thought, so what if JPA getReference() proxy doesn't provide that functionality. I can just write my own proxy.

Now, we can all argue that selects on primary keys are as fast as a query can get and it's not really something to go to great lengths to avoid. But for those of us who can't handle it due to one reason or another, below is an implementation of such a proxy. But before i you see the implementation, see it's usage and how simple it is to use.

USAGE

Order example = ProxyHandler.getReference(Order.class, 3);
example.setType("ABCD");
example.setCost(10);
PersistenceService.save(example);

And this would fire the following query -

UPDATE Order SET type = 'ABCD' and cost = 10 WHERE id = 3;

and even if you want to insert, you can still do PersistenceService.save(new Order("a", 2)); and it would fire an insert as it should.

IMPLEMENTATION

Add this to your pom.xml -

<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>3.2.10</version>
</dependency>

Make this class to create dynamic proxy -

@SuppressWarnings("unchecked")
public class ProxyHandler {

public static <T> T getReference(Class<T> classType, Object id) {
    if (!classType.isAnnotationPresent(Entity.class)) {
        throw new ProxyInstantiationException("This is not an entity!");
    }

    try {
        Enhancer enhancer = new Enhancer();
        enhancer.setSuperclass(classType);
        enhancer.setCallback(new ProxyMethodInterceptor(classType, id));
        enhancer.setInterfaces((new Class<?>[]{EnhancedProxy.class}));
        return (T) enhancer.create();
    } catch (Exception e) {
        throw new ProxyInstantiationException("Error creating proxy, cause :" + e.getCause());
    }
}

Make an interface with all the methods -

public interface EnhancedProxy {
    public String getJPQLUpdate();
    public HashMap<String, Object> getModifiedFields();
}

Now, make an interceptor which will allow you to implement these methods on your proxy -

import com.anil.app.exception.ProxyInstantiationException;
import javafx.util.Pair;
import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;

import javax.persistence.Id;
import java.lang.reflect.Field;
import java.lang.reflect.Method;
import java.util.*;

    this.classType = classType;
    this.target = classType.newInstance();
    this.primaryKey = new Pair<>(getPrimaryKeyField().getName(), id);
}

static {
    enhancedMethods = new HashSet<>();
    for (Method method : EnhancedProxy.class.getDeclaredMethods()) {
        enhancedMethods.add(method.getName());

    //intercept enhanced methods

        return method.invoke(this, args);
    }

    else
        return proxy.invokeSuper(obj, args);
}

                modifiedFields.put(field.getName(), finalValue);

        }
    } catch (Exception e) {
        return null;
    }
    return modifiedFields;
}

@Override
public String getJPQLUpdate() {
    HashMap<String, Object> modifiedFields = getModifiedFields();
    if (modifiedFields == null || modifiedFields.isEmpty()) {
        return null;
    }
    StringBuilder fieldsToSet = new StringBuilder();
    for (String field : modifiedFields.keySet()) {
        fieldsToSet.append(field).append(" = :").append(field).append(" and ");
    }
    fieldsToSet.setLength(fieldsToSet.length() - 4);
    return "UPDATE "
            + classType.getSimpleName()
            + " SET "
            + fieldsToSet

private Field getPrimaryKeyField() throws ProxyInstantiationException {
    for (Field field : classType.getDeclaredFields()) {
        field.setAccessible(true);
        if (field.isAnnotationPresent(Id.class))
            return field;
    }
    throw new ProxyInstantiationException("Entity class doesn't have a primary key!");
}
}

And the exception class -

public class ProxyInstantiationException extends RuntimeException {
public ProxyInstantiationException(String message) {
    super(message);
}

A service to save using this proxy -

@Service
public class PersistenceService {

@PersistenceContext
private EntityManager em;

@Transactional
private void save(Object entity) {
    // update entity for proxies
    if (entity instanceof EnhancedProxy) {
        EnhancedProxy proxy = (EnhancedProxy) entity;
        Query updateQuery = em.createQuery(proxy.getJPQLUpdate());
        for (Entry<String, Object> entry : proxy.getModifiedFields().entrySet()) {
            updateQuery.setParameter(entry.getKey(), entry.getValue());
        }
        updateQuery.executeUpdate();
    // insert otherwise
    } else {
        em.persist(entity);
    }

}
}

My solution is to pull on the other working copy and then do:

git log --pretty="format:" --name-only -n1 | xargs git checkout HEAD^1

which says get all the file paths in the latest comment, and check them out from the parent of HEAD. Job done.

Create a function like so:

CREATE FUNCTION dbo.fn_FileExists(@path varchar(512))
RETURNS BIT
AS
BEGIN
     DECLARE @result INT
     EXEC master.dbo.xp_fileexist @path, @result OUTPUT
     RETURN cast(@result as bit)
END;
GO

Edit your table and add a computed column (IsExists BIT). Set the expression to:

dbo.fn_FileExists(filepath)

Then just select:

SELECT * FROM dbo.MyTable where IsExists = 1

Update:

To use the function outside a computed column:

select id, filename, dbo.fn_FileExists(filename) as IsExists
from dbo.MyTable

Update:

If the function returns 0 for a known file, then there is likely a permissions issue. Make sure the SQL Server's account has sufficient permissions to access the folder and files. Read-only should be enough.

And YES, by default, the 'NETWORK SERVICE' account will not have sufficient right into most folders. Right click on the folder in question and select 'Properties', then click on the 'Security' tab. Click 'Edit' and add 'Network Service'. Click 'Apply' and retest.

As said, the objectForKey: datatype is :(id)aKey whereas the valueForKey: datatype is :(NSString *)key.

For example:

 NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:[NSArray arrayWithObject:@"123"],[NSNumber numberWithInteger:5], nil];

 NSLog(@"objectForKey : --- %@",[dict objectForKey:[NSNumber numberWithInteger:5]]);  
    //This will work fine and prints (    123    )  

 NSLog(@"valueForKey  : --- %@",[dict valueForKey:[NSNumber numberWithInteger:5]]); 
    //it gives warning "Incompatible pointer types sending 'NSNumber *' to parameter of type 'NSString *'"   ---- This will crash on runtime. 

So, valueForKey: will take only a string value and is a KVC method, whereas objectForKey: will take any type of object.

The value in objectForKey will be accessed by the same kind of object.

check this code:

CREATE TRIGGER trig_Update_Employee ON [EmployeeResult] FOR INSERT AS Begin   
    Insert into Employee (Name, Department)  
    Select Distinct i.Name, i.Department   
        from Inserted i
        Left Join Employee e on i.Name = e.Name and i.Department = e.Department
        where e.Name is null
End

You are logging sup directly which is a string

console.log('sup')

Also you are using the wrong id

The template says #main_search but you are using #searchBar

I suppose you are trying this out

$(function() {
   var sup = $('#main_search').val('hi')
   console.log(sup);  // sup is a variable here
});

Just add this small script as depicted in https://developers.google.com/web/updates/2017/09/autoplay-policy-changes#webaudio

<head>
<script>
window.onload = function() {
  var context = new AudioContext();
}
</script>
</head>

Than this will work as you want:

<audio autoplay>
      <source src="hal_9000_sorry_dave.mp3">
</audio>

Here's an article in devx.com that says:

Creating a non-clustered index that contains all the columns used in a SQL query, a technique called index covering

I can only suppose that a covered query is a query that has an index that covers all the columns in its returned recordset. One caveat - the index and query would have to be built as to allow the SQL server to actually infer from the query that the index is useful.

For example, a join of a table on itself might not benefit from such an index (depending on the intelligence of the SQL query execution planner):

PersonID ParentID Name
1        NULL     Abe
2        NULL     Bob
3        1        Carl
4        2        Dave

Let's assume there's an index on PersonID,ParentID,Name - this would be a covering index for a query like:

SELECT PersonID, ParentID, Name FROM MyTable

But a query like this:

SELECT PersonID, Name FROM MyTable LEFT JOIN MyTable T ON T.PersonID=MyTable.ParentID

Probably wouldn't benifit so much, even though all of the columns are in the index. Why? Because you're not really telling it that you want to use the triple index of PersonID,ParentID,Name.

Instead, you're building a condition based on two columns - PersonID and ParentID (which leaves out Name) and then you're asking for all the records, with the columns PersonID, Name. Actually, depending on implementation, the index might help the latter part. But for the first part, you're better off having other indexes.

You can use the this customization to change the default mapping to java.util.Date

<xsd:annotation>
<xsd:appinfo>
    <jaxb:globalBindings>
        <jaxb:javaType name="java.util.Date" xmlType="xsd:dateTime"
                 parseMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.parseDateTime"
                 printMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.printDateTime"/>
    </jaxb:globalBindings>
</xsd:appinfo>

map creates a new list by applying a function to every element of the source:

xs = [1, 2, 3]

# all of those are equivalent — the output is [2, 4, 6]
# 1. map
ys = map(lambda x: x * 2, xs)
# 2. list comprehension
ys = [x * 2 for x in xs]
# 3. explicit loop
ys = []
for x in xs:
    ys.append(x * 2)

n-ary map is equivalent to zipping input iterables together and then applying the transformation function on every element of that intermediate zipped list. It's not a Cartesian product:

xs = [1, 2, 3]
ys = [2, 4, 6]

def f(x, y):
    return (x * 2, y // 2)

# output: [(2, 1), (4, 2), (6, 3)]
# 1. map
zs = map(f, xs, ys)
# 2. list comp
zs = [f(x, y) for x, y in zip(xs, ys)]
# 3. explicit loop
zs = []
for x, y in zip(xs, ys):
    zs.append(f(x, y))

I've used zip here, but map behaviour actually differs slightly when iterables aren't the same size — as noted in its documentation, it extends iterables to contain None.

I suggest playing with the :before attribute and seeing what you can achieve with it. It will mean your code really is limited to nice new browsers, and excludes the (annoyingly large) section of the market still using rubbish old browsers,

Something like the following, which forces a fixed with on the items. Yes, I know it's less elegant to have to choose the width yourself, but using CSS for your layout is like undercover police work: however good your motives, it always gets messy.

li:before {
  content: counter(item) ") ";
  counter-increment: item;
  display: marker;
  width: 2em;
}

But you're going to have to experiment to find the exact solution.

Just run it without options.

You haven't included package declarations in the OP but it is possible that neither @SpringBootApplication nor @ComponentScan are scanning for your @Component.

The @ComponentScan Javadoc states:

Either basePackageClasses or basePackages (or its alias value) may be specified to define specific packages to scan. If specific packages are not defined, scanning will occur from the package of the class that declares this annotation.

ISTR wasting a lot of time on this before and found it easiest to simply move my application class to the highest package in my app's package tree.

More recently I encountered a gotcha were the property was being read before the value insertion had been done. Jesse's answer helped as @PostConstruct seems to be the earliest you can read the inserted values, and of course you should let Spring call this.

According to Django documentation, inline formsets are for this purpose: "Inline formsets is a small abstraction layer on top of model formsets. These simplify the case of working with related objects via a foreign key".

See https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#inline-formsets

Let me emphasise that Docker doesn't even allow mixed characters.

Good: docker build -t myfirstechoimage:0.1 .

Bad: docker build -t myFirstEchoImage:0.1 .

It's very easy:

numb = raw_input('Input Line: ')
fiIn = open('file.txt').readlines()
for lines in fiIn:
   if numb == lines[0]:
      print lines

sqlite3 yourdb .dump > /tmp/db.txt
edit /tmp/db.txt change column name in Create line
sqlite2 yourdb2 < /tmp/db.txt
mv/move yourdb2 yourdb

Maybe something like: $(".subclass", this);
