You have your storyboard set up to expect an outlet called tableView but the actual outlet name is myTableView.

If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.

Only the "drop armageddon" solution worked for me:

• remove app from device
• clean project
• run new install on device

Building on what is mentioned in the comments, the simplest solution would be:

@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Collection<BudgetDTO> updateConsumerBudget(@RequestBody SomeDto someDto) throws GeneralException, ParseException {

    //whatever

}

class SomeDto {

   private List<WhateverBudgerPerDateDTO> budgetPerDate;


  //getters setters
}

The solution assumes that the HTTP request you are creating actually has

Content-Type:application/json instead of text/plain

If you want to load the partial view directly inside the main view you could use the Html.Action helper:

@Html.Action("Load", "Home")

or if you don't want to go through the Load action use the HtmlPartialAsync helper:

@await Html.PartialAsync("_LoadView")

If you want to use Ajax.ActionLink, replace your Html.ActionLink with:

@Ajax.ActionLink(
    "load partial view", 
    "Load", 
    "Home", 
    new AjaxOptions { UpdateTargetId = "result" }
)

and of course you need to include a holder in your page where the partial will be displayed:

<div id="result"></div>

Also don't forget to include:

<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>

in your main view in order to enable Ajax.* helpers. And make sure that unobtrusive javascript is enabled in your web.config (it should be by default):

<add key="UnobtrusiveJavaScriptEnabled" value="true" />

I think what you're trying to do should be done with multiple Activities. If you're learning Android, understanding Activities is something you're going to have to tackle. Trying to write a whole app with just one Activity will end up being a lot more difficult. Read this article to get yourself started, then you should end up with something more like this:

View.OnClickListener handler = new View.OnClickListener(){
    public void onClick(View v) {

        switch (v.getId()) {

            case R.id.DownloadView: 
                // doStuff
                startActivity(new Intent(ThisActivity.this, DownloadActivity.class));
                break;
            case R.id.AppView: 
                // doStuff
                startActivity(new Intent(ThisActivity.this, AppActivity.class));
                break;
        }
    }
};

findViewById(R.id.DownloadView).setOnClickListener(handler);
findViewById(R.id.AppView).setOnClickListener(handler);

See the answer by @david-east for the correct way to handle the issue

This answer is only relevant to a bug with jQuery 1.5 when using the file: protocol.

I had a similar problem recently when upgrading to jQuery 1.5. Despite getting a correct response the error handler fired. I resolved it by using the complete event and then checking the status value. e.g:

complete: function (xhr, status) {
    if (status === 'error' || !xhr.responseText) {
        handleError();
    }
    else {
        var data = xhr.responseText;
        //...
    }
}

I had the same problem, but a slightly different solution was called for. The problem in this case was the class of the File Owner, rather than the class of the View. To set this, I had to click the "backwards play" icon in the lower left corner of the Interface Builder window, and options then appeared that isolated the characteristics of the File Owner, the First Responder, and the View. Clicking on the first one (a large transparent box), enabled me to then set its custom class as suggested above.

This is a great question (+1) and the answers were almost helpful ;) Sorry guys, but I had a heck of a time slogging through this, though both Gonso & AVeryDev gave good hints. Hopefully, this answer will help others.

MyVC is the view controller holding all this stuff.

MySubview is the view that we want to load from a xib

• In MyVC.xib, create a view of type MySubView that is the right size & shape & positioned where you want it.

• In MyVC.h, have

  IBOutlet MySubview *mySubView
  // ...
  @property (nonatomic, retain) MySubview *mySubview;
  

• In MyVC.m, @synthesize mySubView; and don't forget to release it in dealloc.

• In MySubview.h, have an outlet/property for UIView *view (may be unnecessary, but worked for me.) Synthesize & release it in .m
• In MySubview.xib
  • set file owner type to MySubview, and link the view property to your view.
  • Lay out all the bits & connect to the IBOutlet's as desired

• Back in MyVC.m, have

  NSArray *xibviews = [[NSBundle mainBundle] loadNibNamed: @"MySubview" owner: mySubview options: NULL];
  MySubview *msView = [xibviews objectAtIndex: 0];
  msView.frame = mySubview.frame;
  UIView *oldView = mySubview;
  // Too simple: [self.view insertSubview: msView aboveSubview: mySubview];
  [[mySubview superview] insertSubview: msView aboveSubview: mySubview]; // allows nesting
  self.mySubview = msView;
  [oldCBView removeFromSuperview];
  

The tricky bit for me was: the hints in the other answers loaded my view from the xib, but did NOT replace the view in MyVC (duh!) -- I had to swap that out on my own.

Also, to get access to mySubview's methods, the view property in the .xib file must be set to MySubview. Otherwise, it comes back as a plain-old UIView.

If there's a way to load mySubview directly from its own xib, that'd rock, but this got me where I needed to be.

Here is Code for Smooth animation, might Be helpful for many developers.
I found this snippet of code from this tutorial.

CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[animation setAutoreverses:YES];
[animation setFromValue:[NSNumber numberWithFloat:1.3f]];
[animation setToValue:[NSNumber numberWithFloat:1.f]];
[animation setDuration:2.f];
[animation setRemovedOnCompletion:NO];

[animation setFillMode:kCAFillModeForwards];
[[self.myView layer] addAnimation:animation forKey:@"scale"];/// add here any Controller that you want t put Smooth animation.

The only way to remove the ADT plugin from Eclipse is to go to Help > About Eclipse/About ADT > Installation Details.

Select a plug-in you want to uninstall, then click Uninstall... button at the bottom.

If you cannot remove ADT from this location, then your best option is probably to start fresh with a clean Eclipse install.

Update for Python3: (quoted from the already-answered answer, since the last edit/comment here suggested a deprecated method)

In Python 3, reload was moved to the imp module. In 3.4, imp was deprecated in favor of importlib, and reload was added to the latter. When targeting 3 or later, either reference the appropriate module when calling reload or import it.

Takeaway:

• Python3 >= 3.4: importlib.reload(packagename)
• Python3 < 3.4: imp.reload(packagename)
• Python2: continue below

Use the reload builtin function:

https://docs.python.org/2/library/functions.html#reload

When reload(module) is executed:

• Python modules’ code is recompiled and the module-level code reexecuted, defining a new set of objects which are bound to names in the module’s dictionary. The init function of extension modules is not called a second time.
• As with all other objects in Python the old objects are only reclaimed after their reference counts drop to zero.
• The names in the module namespace are updated to point to any new or changed objects.
• Other references to the old objects (such as names external to the module) are not rebound to refer to the new objects and must be updated in each namespace where they occur if that is desired.

Example:

# Make a simple function that prints "version 1"
shell1$ echo 'def x(): print "version 1"' > mymodule.py

# Run the module
shell2$ python
>>> import mymodule
>>> mymodule.x()
version 1

# Change mymodule to print "version 2" (without exiting the python REPL)
shell2$ echo 'def x(): print "version 2"' > mymodule.py

# Back in that same python session
>>> reload(mymodule)
<module 'mymodule' from 'mymodule.pyc'>
>>> mymodule.x()
version 2

One of the most interesting features in HTML5 is the ability to store data locally and to allow the application to run offline. There are three different APIs that deal with these features and choosing one depends on what exactly you want to do with the data you're planning to store locally:

1. Web storage: For basic local storage with key/value pairs
2. Offline storage: Uses a manifest to cache entire files for offline use
3. Web database: For relational database storage

For more reference see Introducing the HTML5 storage APIs

And how to use

A Lambda Function, or a Small Anonymous Function, is a self-contained block of functionality that can be passed around and used in your code. Lambda has different names in different programming languages – Lambda in Python and Kotlin, Closure in Swift, or Block in C and Objective-C. Although lambda's meaning is quite similar for these languages it has slight distinctions sometimes.

Let's see how Lambda (Closure) works in Swift 4.2 with sorted() method – from normal function till the shortest expression:

let coffee: [String] = ["Cappuccino", "Espresso", "Latte", "Ristretto"]

1. Normal Function

func backward(_ n1: String, _ n2: String) -> Bool {
    return n1 > n2
}
var reverseOrder = coffee.sorted(by: backward)


// RESULT: ["Ristretto", "Latte", "Espresso", "Cappuccino"]

2. Closure Expression

reverseOrder = coffee.sorted(by: { (n1: String, n2: String) -> Bool in
    return n1 > n2
})

3. Inline Closure Expression

reverseOrder = coffee.sorted(by: { (n1: String, n2: String) -> Bool in return n1 > n2 } )

4. Inferring Type From Context

reverseOrder = coffee.sorted(by: { n1, n2 in return n1 > n2 } )

5. Implicit Returns from Single-Expression Closures

reverseOrder = coffee.sorted(by: { n1, n2 in n1 > n2 } )

6. Shorthand Argument Names

reverseOrder = coffee.sorted(by: { $0 > $1 } )

// $0 and $1 are closure’s first and second String arguments.

7. Operator Methods

reverseOrder = coffee.sorted(by: >)

// RESULT: ["Ristretto", "Latte", "Espresso", "Cappuccino"]

Hope this helps.

I'll add that arrays are very low-level constructs in C++ and you should try to stay away from them as much as possible when "learning the ropes" -- even Bjarne Stroustrup recommends this (he's the designer of C++).

Vectors come very close to the same performance as arrays, but with a great many conveniences and safety features. You'll probably start using arrays when interfacing with API's that deal with raw arrays, or when building your own collections.

Using a List as an intermediary is the easiest way, as others have described, but since your input is an array and you don't just want to keep the data in a List, I presume you might be concerned about performance.

The most efficient method is likely allocating a new array and then using Array.Copy or Array.CopyTo. This is not hard if you just want to add an item to the end of the list:

public static T[] Add<T>(this T[] target, T item)
{
    if (target == null)
    {
        //TODO: Return null or throw ArgumentNullException;
    }
    T[] result = new T[target.Length + 1];
    target.CopyTo(result, 0);
    result[target.Length] = item;
    return result;
}

I can also post code for an Insert extension method that takes a destination index as input, if desired. It's a little more complicated and uses the static method Array.Copy 1-2 times.

The Three20 library has a way to do this:

  UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle: @"Title" style:UIBarButtonItemStylePlain 
                                                                target:self action:@selector(foo)];

  UIColor* darkBlue = RGBCOLOR(109, 132, 162);

  TTShapeStyle* style = [TTShapeStyle styleWithShape:[TTRoundedLeftArrowShape shapeWithRadius:4.5] next:
    [TTShadowStyle styleWithColor:RGBCOLOR(255,255,255) blur:1 offset:CGSizeMake(0, 1) next:
    [TTReflectiveFillStyle styleWithColor:darkBlue next:
    [TTBevelBorderStyle styleWithHighlight:[darkBlue shadow]
                                     shadow:[darkBlue multiplyHue:1 saturation:0.5 value:0.5]
                                      width:1 lightSource:270 next:
    [TTInsetStyle styleWithInset:UIEdgeInsetsMake(0, -1, 0, -1) next:
    [TTBevelBorderStyle styleWithHighlight:nil shadow:RGBACOLOR(0,0,0,0.15)
                                        width:1 lightSource:270 next:nil]]]]]];

  TTView* view = [[[TTView alloc] initWithFrame:CGRectMake(0, 0, 80, 35)] autorelease];
  view.backgroundColor = [UIColor clearColor];
  view.style = style;
  backButton.customView = view;


  self.navigationItem.leftBarButtonItem = backButton;

Since the question was using JQuery, here’s a JQuery plugin based on Daniel Elliott’s code:

$.fn.cssAsHex = function(colorProp) {

    var hexDigits = '0123456789abcdef';

    function hex(x) {
        return isNaN(x) ? '00' : hexDigits[(x - x % 16) / 16] + hexDigits[x % 16];
    };

    // Convert RGB color to Hex format
    function rgb2hex(rgb) {
        var rgbRegex = rgb.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
        return '#' + hex(rgbRegex[1]) + hex(rgbRegex[2]) + hex(rgbRegex[3]);
    };

    return rgb2hex(this.css(colorProp));
};

Use it like:

var hexBackgroundColor = $('#myElement').cssAsHex('background-color');

I don't bother with dropping the alternate temp in case i need to reclaim storage again in the future...

1. from temp group set default to stand-alone temp
2. wait awhile, then resize members of temp group
3. set default back to temp group
4. wait awhile, resize stand alone temp. there's no rush to do the last step

beginupd.getTime() will give you time in milliseconds since January 1, 1970, 00:00:00 GMT till the time you have specified in Date object

XJC is included in the bin directory in the JDK starting with Java SE 6. For an example see:

• http://blog.bdoughan.com/2010/09/processing-atom-feeds-with-jaxb.html

The contents of the blog are the following:

Processing Atom Feeds with JAXB Atom is an XML format for representing web feeds. A standard format allows reader applications to display feeds from different sources. In this example we will process the Atom feed for this blog.

Demo

In this example we will use JAXB to convert the Atom XML feed corresponding to this blog to objects and then back to XML.

import java.io.InputStream;
import java.net.URL;
import javax.xml.bind.*;
import javax.xml.transform.stream.StreamSource;
import org.w3._2005.atom.FeedType;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance("org.w3._2005.atom");

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        URL url = new URL("http://bdoughan.blogspot.com/atom.xml");
        InputStream xml = url.openStream();
        JAXBElement<feedtype> feed = unmarshaller.unmarshal(new StreamSource(xml), FeedType.class);
        xml.close();

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(feed, System.out);
    }

}

Due to the locking implementation issues, MySQL does not allow referencing the affected table with DELETE or UPDATE.

You need to make a JOIN here instead:

DELETE  gc.*
FROM    guide_category AS gc 
LEFT JOIN
        guide AS g 
ON      g.id_guide = gc.id_guide
WHERE   g.title IS NULL

or just use a NOT IN:

DELETE  
FROM    guide_category AS gc 
WHERE   id_guide NOT IN
        (
        SELECT  id_guide
        FROM    guide
        )

! [rejected] master -> master (fetch first) error: failed to push some refs to '[email protected]:'

Successfully solved the problem using --force command. so, you must used
git push origin master --force

If you happen to be using a mac keyboard on linux (ubuntu), Insert is actually fn + return. You can also click on the zero of the number pad to switch between the cursor types.

Took me a while to figure that out. :-P

Note: there are also negative numbers.

function isOddInteger(n)
{
   return isInteger(n) && (n % 2 !== 0);
}

where

function isInteger(n)
{
   return n === parseInt(n, 10);
}

So many answers doing half the work. Yes, !!X could be read as "the truthiness of X [represented as a boolean]". But !! isn't, practically speaking, so important for figuring out whether a single variable is (or even if many variables are) truthy or falsy. !!myVar === true is the same as just myVar. Comparing !!X to a "real" boolean isn't really useful.

What you gain with !! is the ability to check the truthiness of multiple variables against each other in a repeatable, standardized (and JSLint friendly) fashion.

Simply casting :(

That is...

• 0 === false is false.
• !!0 === false is true.

The above's not so useful. if (!0) gives you the same results as if (!!0 === false). I can't think of a good case for casting a variable to boolean and then comparing to a "true" boolean.

See "== and !=" from JSLint's directions (note: Crockford is moving his site around a bit; that link is liable to die at some point) for a little on why:

The == and != operators do type coercion before comparing. This is bad because it causes ' \t\r\n' == 0 to be true. This can mask type errors. JSLint cannot reliably determine if == is being used correctly, so it is best to not use == and != at all and to always use the more reliable === and !== operators instead.

If you only care that a value is truthy or falsy, then use the short form. Instead of
(foo != 0)

just say
(foo)

and instead of
(foo == 0)

say
(!foo)

Note that there are some unintuitive cases where a boolean will be cast to a number (true is cast to 1 and false to 0) when comparing a boolean to a number. In this case, !! might be mentally useful. Though, again, these are cases where you're comparing a non-boolean to a hard-typed boolean, which is, imo, a serious mistake. if (-1) is still the way to go here.

And things get even crazier depending on your engine. WScript, for instance, wins the prize.

function test()
{
    return (1 === 1);
}
WScript.echo(test());

Because of some historical Windows jive, that'll output -1 in a message box! Try it in a cmd.exe prompt and see! But WScript.echo(-1 == test()) still gives you 0, or WScript's false. Look away. It's hideous.

Comparing truthiness :)

But what if I have two values I need to check for equal truthi/falsi-ness?

Pretend we have myVar1 = 0; and myVar2 = undefined;.

• myVar1 === myVar2 is 0 === undefined and is obviously false.
• !!myVar1 === !!myVar2 is !!0 === !!undefined and is true! Same truthiness! (In this case, both "have a truthiness of falsy".)

So the only place you'd really need to use "boolean-cast variables" would be if you had a situation where you're checking if both variables have the same truthiness, right? That is, use !! if you need to see if two vars are both truthy or both falsy (or not), that is, of equal (or not) truthiness.

I can't think of a great, non-contrived use case for that offhand. Maybe you have "linked" fields in a form?

if (!!customerInput.spouseName !== !!customerInput.spouseAge ) {
    errorObjects.spouse = "Please either enter a valid name AND age " 
        + "for your spouse or leave all spouse fields blank.";
}

So now if you have a truthy for both or a falsy for both spouse name and age, you can continue. Otherwise you've only got one field with a value (or a very early arranged marriage) and need to create an extra error on your errorObjects collection.

EDIT 24 Oct 2017, 6 Feb 19:

3rd party libraries that expect explicit Boolean values

Here's an interesting case... !! might be useful when 3rd party libs expect explicit Boolean values.

For instance, False in JSX (React) has a special meaning that's not triggered on simple falsiness. If you tried returning something like the following in your JSX, expecting an int in messageCount...

{messageCount && <div>You have messages!</div>}

... you might be surprised to see React render a 0 when you have zero messages. You have to explicitly return false for JSX not to render. The above statement returns 0, which JSX happily renders, as it should. It can't tell you didn't have Count: {messageCount && <div>Get your count to zero!</div>} (or something less contrived).

• One fix involves the bangbang, which coerces 0 into !!0, which is false:
  {!!messageCount && <div>You have messages!</div>}

• JSX' docs suggest you be more explicit, write self-commenting code, and use a comparison to force to a Boolean.
  {messageCount > 0 && <div>You have messages!</div>}

• I'm more comfortable handling falsiness myself with a ternary --
  {messageCount ? <div>You have messages!</div> : false}

Same deal in Typescript: If you have a function that returns a boolean (or you're assigning a value to a boolean variable), you [usually] can't return/assign a boolean-y value; it has to be a strongly typed boolean. This means, iff myObject is strongly typed, return !myObject; works for a function returning a boolean, but return myObject; doesn't. You have to return !!myObject to match Typescript's expectations.

The exception for Typescript? If myObject was an any, you're back in JavaScript's Wild West and can return it without !!, even if your return type is a boolean.

Keep in mind that these are JSX & Typescript conventions, not ones inherent to JavaScript.

But if you see strange 0s in your rendered JSX, think loose falsy management.

It uses c#, and unityscript(javascript), which is supported by the source code in c++, and c++ plugin support(source code, and plugins require pro).

The unity3d script reference is really easy to understand/use if needed, probably the easiest out of engines like cryengine, udk, etc.

Hope this helps.

Using the {# #} notation, like so:

{# Everything you see here is a comment. It won't show up in the HTML output. #}

The default display style for a div is "block." This means that each new div will be under the prior one.

You can:

Override the flow style by using float as @Sarfraz suggests.

or

Change your html to use something other than divs for elements you want on the same line. I suggest that you just leave out the divs for the "last_name" field

<form action="/users" method="post"><div style="margin:0;padding:0">
  <div>
    <label for="username">First Name</label>
    <input id="user_first_name" name="user[first_name]" size="30" type="text" />

    <label for="name">Last Name</label>
    <input id="user_last_name" name="user[last_name]" size="30" type="text" />
  </div>
  ... rest is same

numpy.random.randint accepts a third argument (size) , in which you can specify the size of the output array. You can use this to create your DataFrame -

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

Here - np.random.randint(0,100,size=(100, 4)) - creates an output array of size (100,4) with random integer elements between [0,100) .

Demo -

import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

which produces:

     A   B   C   D
0   45  88  44  92
1   62  34   2  86
2   85  65  11  31
3   74  43  42  56
4   90  38  34  93
5    0  94  45  10
6   58  23  23  60
..  ..  ..  ..  ..

Just follow these steps:

1) Install eclipse
2) Import Apache to eclipse
3) Install mysql
4) Download mysqlconnector/J
5) Unzip the zipped file navigate through it until you get the bin file in it. Then place all files that are present in the folder containing bin to C:\Program Files\mysql\mysql server5.1/ then give the same path as the address while defining the driver in eclipse.

That's all very easy guys.

You haven't actually asked a question, but assuming you have one, this could be your answer...

Assuming all characters, except the "Special Characters" are allowed you can write

String regex = "^[^<>'\"/;`%]*$";

#main {
   display: table;
} 
#navigation, #content {
   display: table-cell;
}

Look at this example.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/activity_register_header"
    android:minHeight="50dp"
    android:orientation="vertical"
    android:visibility="gone" />

Try this piece of code..For me this code worked..

String courseID = "Comp-101";
List<String> scores = new ArrayList<String> ();
scores.add("100");
scores.add("90");
scores.add("80");
scores.add("97");

Map<String, ArrayList<String>> myMap = new HashMap<String, ArrayList<String>>();
myMap.put(courseID, scores);

Hope this helps!

I think that depends on your window manager.

I'm a windows user, so this might be a wrong guess, but: Isn't there something called X-Server running on linux machines - at least on ones that might be interesting targets for VNC - that you can connect to with "X-Clients"?

VNC just takes everything that's on the screen and "tunnels it through your network". If I'm not totally wrong then the "X" protocol should give you the chance to use your client's desktop resolution.

Give X-Server on Wikipedia a try, that might give you a rough overview.

1. Remove package folder from vendor folder (Manual delete)
2. remove it from 'composer.json' & 'composer.lock' files
3. remove it from 'config/app.php' & 'bootstrap/cache/config.php' files
4. composer remove package-name
5. php artisan cache:clear & php artisan config:clear

  var tag = document.createElement('script');

        $('#my_field').addClass('bad');_x000D_
    };

Try using the @ symbol before the url string. Import your css in the following manner:

import Vue from 'vue'

require('@/assets/styles/main.css')

In your App.vue file you can do this to import a css file in the style tag

<template>
  <div>
  </div>
</template>

<style scoped src="@/assets/styles/mystyles.css">
</style>

The instanceof operator does not need explicit null checks, as it does not throw a NullPointerException if the operand is null.

At run time, the result of the instanceof operator is true if the value of the relational expression is not null and the reference could be cast to the reference type without raising a class cast exception.

If the operand is null, the instanceof operator returns false and hence, explicit null checks are not required.

Consider the below example,

public static void main(String[] args) {
         if(lista != null && lista instanceof ArrayList) {                     //Violation
                System.out.println("In if block");
         }
         else {
                System.out.println("In else block");
         }
}

The correct usage of instanceof is as shown below,

public static void main(String[] args) {
      
         if(lista instanceof ArrayList){                     //Correct way
                  System.out.println("In if block");
         }
            else {
                 System.out.println("In else block");
         }  
}

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.

They should be

server {
    listen      80;
    server_name www.domain1.com;
    root /var/www/domain1;
}

server {
    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;
}

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

Explain only shows how the optimizer thinks the query will execute.

To show the real plan, you will need to run the sql once. Then use the same session run the following:

@yoursql 
select * from table(dbms_xplan.display_cursor()) 

This way can show the real plan used during execution. There are several other ways in showing plan using dbms_xplan. You can Google with term "dbms_xplan".

move you mouse over the "Hello, playground" on the right side bar, you will see an eye icon and a small circle icon next it. Just click on the circle one to show the detail page and console output!

Dictionary<,> is the equivalent. While it doesn't have a Get(...) method, it does have an indexed property called Item which you can access in C# directly using index notation:

class Test {
  Dictionary<int,String> entities;

  public String getEntity(int code) {
    return this.entities[code];
  }
}

If you want to use a custom key type then you should consider implementing IEquatable<> and overriding Equals(object) and GetHashCode() unless the default (reference or struct) equality is sufficient for determining equality of keys. You should also make your key type immutable to prevent weird things happening if a key is mutated after it has been inserted into a dictionary (e.g. because the mutation caused its hash code to change).

If you don't want to use the class method you can use parent-child method to make changes in the text box.

For eg. I've made a form in my form div.

HTML Code:

<div class="form">
    <textarea name="message" rows="10" cols="30" >Describe your project in detail.</textarea>
</div>

Now CSS code will be like:

.form textarea {
    height: 220px;
    width: 342px;
}

Problem solved.

You may write your "main.py" like this:

#!/usr/bin/env python

__all__=["somevar", "do_something"]

somevar=""

def do_something():
    pass #blahblah

if __name__=="__main__":
    do_something()

Indeed, window.location.origin works fine in browsers following standards, but guess what. IE isn't following standards.

So because of that, this is what worked for me in IE, FireFox and Chrome:

var full = location.protocol+'//'+location.hostname+(location.port ? ':'+location.port: '');

but for possible future enhancements which could cause conflicts, I specified the "window" reference before the "location" object.

var full = window.location.protocol+'//'+window.location.hostname+(window.location.port ? ':'+window.location.port: '');

Why not pass an object to v-bind:class to dynamically toggle the class:

<div v-bind:class="{ disabled: order.cancelled_at }"></div>

This is what is recommended by the Vue docs.

A much simpler approach I found is to use plt.imsave :

    import matplotlib.pyplot as plt
    arr = plt.imread(path)
    plt.imsave('test.png', arr)

One thing you should know is $ prefix refers to an Angular Method, $$ prefixes refers to angular methods that you should avoid using.

below is an example template and its controllers, we'll explore how $broadcast/$on can help us achieve what we want.

<div ng-controller="FirstCtrl">
    <input ng-model="name"/> 
    <button ng-click="register()">Register </button>
</div>

<div ng-controller="SecondCtrl">
    Registered Name: <input ng-model="name"/> 
</div>

The controllers are

app.controller('FirstCtrl', function($scope){
    $scope.register = function(){

    }
});

app.controller('SecondCtrl', function($scope){

});

My question to you is how do you pass the name to the second controller when a user clicks register? You may come up with multiple solutions but the one we're going to use is using $broadcast and $on.

$broadcast vs $emit

Which should we use? $broadcast will channel down to all the children dom elements and $emit will channel the opposite direction to all the ancestor dom elements.

The best way to avoid deciding between $emit or $broadcast is to channel from the $rootScope and use $broadcast to all its children. Which makes our case much easier since our dom elements are siblings.

Adding $rootScope and lets $broadcast

app.controller('FirstCtrl', function($rootScope, $scope){
    $scope.register = function(){
        $rootScope.$broadcast('BOOM!', $scope.name)
    }
});

Note we added $rootScope and now we're using $broadcast(broadcastName, arguments). For broadcastName, we want to give it a unique name so we can catch that name in our secondCtrl. I've chosen BOOM! just for fun. The second arguments 'arguments' allows us to pass values to the listeners.

Receiving our broadcast

In our second controller, we need to set up code to listen to our broadcast

app.controller('SecondCtrl', function($scope){
  $scope.$on('BOOM!', function(events, args){
    console.log(args);
    $scope.name = args; //now we've registered!
  })
});

It's really that simple. Live Example

Other ways to achieve similar results

Try to avoid using this suite of methods as it is neither efficient nor easy to maintain but it's a simple way to fix issues you might have.

You can usually do the same thing by using a service or by simplifying your controllers. We won't discuss this in detail but I thought I'd just mention it for completeness.

Lastly, keep in mind a really useful broadcast to listen to is '$destroy' again you can see the $ means it's a method or object created by the vendor codes. Anyways $destroy is broadcasted when a controller gets destroyed, you may want to listen to this to know when your controller is removed.

Yes, the superview is the view that contains your view. Your view shouldn't know which exactly is its view controller, because that would break MVC principles.

The controller, on the other hand, knows which view it's responsible for (self.view = myView), and usually, this view delegates methods/events for handling to the controller.

Typically, instead of a pointer to your view, you should have a pointer to your controller, which in turn can either execute some controlling logic, or pass something to its view.

"using" can also be used to resolve name space conflicts. See http://www.davidarno.org/c-howtos/aliases-overcoming-name-conflicts/ for a short tutorial I wrote on the subject.

If you're looking for a minimal solution that invalidates the cache, this edited version of Dr Manhattan's solution should be sufficient. Note that I'm specifying the root / directory to indicate I want the whole site refreshed.

export AWS_ACCESS_KEY_ID=<Key>
export AWS_SECRET_ACCESS_KEY=<Secret>
export AWS_DEFAULT_REGION=eu-west-1

echo "Invalidating cloudfrond distribution to get fresh cache"
aws cloudfront create-invalidation --distribution-id=<distributionId> --paths / --profile=<awsprofile>

Region Codes can be found here

You'll also need to create a profile using the aws cli. Use the aws configure --profile option. Below is an example snippet from Amazon.

$ aws configure --profile user2

A nice way of doing this with the dataframe api is using the argmax logic like so

  val df = Seq(
    (0,"cat26",30.9), (0,"cat13",22.1), (0,"cat95",19.6), (0,"cat105",1.3),
    (1,"cat67",28.5), (1,"cat4",26.8), (1,"cat13",12.6), (1,"cat23",5.3),
    (2,"cat56",39.6), (2,"cat40",29.7), (2,"cat187",27.9), (2,"cat68",9.8),
    (3,"cat8",35.6)).toDF("Hour", "Category", "TotalValue")

  df.groupBy($"Hour")
    .agg(max(struct($"TotalValue", $"Category")).as("argmax"))
    .select($"Hour", $"argmax.*").show

 +----+----------+--------+
 |Hour|TotalValue|Category|
 +----+----------+--------+
 |   1|      28.5|   cat67|
 |   3|      35.6|    cat8|
 |   2|      39.6|   cat56|
 |   0|      30.9|   cat26|

I solved this by doing git fetch. My error was because I moved my file from my main storage to my secondary storage on windows 10.

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

if you would like to order third party libraries dependencies, try wiredep. This package basically checks each package dependency in bower.json then wire them up for you.

This is another example using defined column/table names.

As of 16/9/2020 most of these answers are not too much consistent any way! Try this new npm package

Sequelize-mig

It completed most known problems in sequelize-auto-migrations and its forks and its maintained and documented!

Its used in a way similar to the known one

Install:

npm install sequelize-mig -g / yarn global add sequelize-mig

then use it like this

sequelize-mig migration:make -n <migration name>

Another method of doing this without writing much code is using the ES5 Object.keys-method:

var arrayWithDuplicates = ['a','b','c','d','a','c'],
    deduper = {};
arrayWithDuplicates.forEach(function (item) {
    deduper[item] = null;
});
var dedupedArray = Object.keys(deduper); // ["a", "b", "c", "d"]

Extracted in a function

function removeDuplicates (arr) {
    var deduper = {}
    arr.forEach(function (item) {
        deduper[item] = null;
    });
    return Object.keys(deduper);
}

Used this for show text

var data = $('#id-selected-input').select2('data'); 
data.forEach(function (item) { 
    alert(item.text); 
})

Way late to this post, but I've got something slightly different to say...

>> "Are email addresses case sensitive?"

Well, "It Depends..." (TM)

Some organizations actually think that's a good idea and their email servers enforce case sensitivity.

So, for those crazy places, "Yes, Emails are case sensitive."

Note: Just because a specification says you can do something does not mean it is a good idea to do so.

The principle of KISS suggests that our systems use case insensitive emails.

Whereas the Robustness principle suggests that we accept case sensitive emails.

Solution:

• Store emails with case sensitivity
• Send emails with case sensitivity
• Perform internal searches with case insensitivity

This would mean that if this email already exists: [email protected]

... and another user comes along and wants to use this email: [email protected]

... that our case insensitive searching logic would return a "That email already exists" error message.

Now, you have a decision to make: Is that solution adequate in your case?

If not, you could charge a convenience fee to those clients that demand support for their case sensitive emails and implement custom logic that allows the [email protected] into your system, even if [email protected] already exists.

In which case your email search/validation logic might look like something this pseudocode:

if (user.paidEmailFee) {
   // case sensitive email
   query = "select * from users where email LIKE ' + user.email + '"
} else {
   // case insensitive email
   query = "select * from users where email ILIKE ' + user.email + '"
}

This way, you are mostly enforcing case insensitivity but allowing customers to pay for this support if they are using email systems that support such nonsense.

p.s. ILIKE is a PostgreSQL keyword: http://www.postgresql.org/docs/9.2/static/functions-matching.html

This probably means that python doesn't know where PyQt5 is located. To check, go into the interactive terminal and type:

import sys
print sys.path

What you probably need to do is add the directory that contains the PyQt5 module to your PYTHONPATH environment variable. If you use bash, here's how:

Type the following into your shell, and add it to the end of the file ~/.bashrc

export PYTHONPATH=/path/to/PyQt5/directory:$PYTHONPATH

where /path/to/PyQt5/directory is the path to the folder where the PyQt5 library is located.

pgrep can get you all of the child PIDs of a parent process. As mentioned earlier $$ is the current scripts PID. So, if you want a script that cleans up after itself, this should do the trick:

trap 'kill $( pgrep -P $$ | tr "\n" " " )' SIGINT SIGTERM EXIT

I've used both approaches, and they both worked fine for me. Whichever one I use, I always try to apply this principle:

If the only possible errors are programmer errors, don't return an error code, use asserts inside the function.

An assertion that validates the inputs clearly communicates what the function expects, while too much error checking can obscure the program logic. Deciding what to do for all the various error cases can really complicate the design. Why figure out how functionX should handle a null pointer if you can instead insist that the programmer never pass one?

Console.WriteLine(curr.ToString("HH:mm"));

You can always create a new Eclipse workspace. The Eclipse.exe -clean option is not sufficient in some cases, for example, if the local history becomes a problem.

Edit:

Eclipse is mostly a collection of third party plugins. And each of those plugins can add some extra useful, useless or problematic information to the central Eclipse workspace meta-data folder.

The problem is that not every plugin participates during the user-issued cleanup routine. Therefore, I'd say that it is a problem in the system design of Eclipse, that it allows plugins to misbehave like this.

And therefore, I'd recommend to make yourself comfortable with the idea of using multiple workspaces and linking-in external project entities into each workspace. Because, this is the only workaround for the given system design, to handle faulty plugins that spam your workspace.

You could add justify-content: space-between to the parent element. In doing so, the children flexbox items will be aligned to opposite sides with space between them.

Updated Example

#container {
    width: 500px;
    border: solid 1px #000;
    display: flex;
    justify-content: space-between;
}

#container {_x000D_
    width: 500px;_x000D_
    border: solid 1px #000;_x000D_
    display: flex;_x000D_
    justify-content: space-between;_x000D_
}_x000D_
_x000D_
#a {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
}_x000D_
_x000D_
#b {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    height: 200px;_x000D_
}

<div id="container">_x000D_
    <div id="a">_x000D_
        a_x000D_
    </div>_x000D_
    <div id="b">_x000D_
        b_x000D_
    </div>_x000D_
</div>

You could also add margin-left: auto to the second element in order to align it to the right.

Updated Example

#b {
    width: 20%;
    border: solid 1px #000;
    height: 200px;
    margin-left: auto;
}

#container {_x000D_
    width: 500px;_x000D_
    border: solid 1px #000;_x000D_
    display: flex;_x000D_
}_x000D_
_x000D_
#a {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    margin-right: auto;_x000D_
}_x000D_
_x000D_
#b {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    height: 200px;_x000D_
    margin-left: auto;_x000D_
}

<div id="container">_x000D_
    <div id="a">_x000D_
        a_x000D_
    </div>_x000D_
    <div id="b">_x000D_
        b_x000D_
    </div>_x000D_
</div>

Refer to the Flask API document for flask.url_for()

Other sample snippets of usage for linking js or css to your template are below.

<script src="{{ url_for('static', filename='jquery.min.js') }}"></script>

<link rel=stylesheet type=text/css href="{{ url_for('static', filename='style.css') }}">

another solution using awk script:

last 1 char:

echo $str | awk '{print substr($0,length,1)}'

last 5 chars:

echo $str | awk '{print substr($0,length-5,5)}'

 Post::create([
      'title' => request('title'),
      'body' => request('body'),
      'user_id' => auth()->id()
    ]);

you dont need the request() as you doing that already pulling the value of body and title

I solved it in my site making this in functions.php

add_action("template_redirect", "start_buffer");
add_action("shutdown", "end_buffer", 999);

function filter_buffer($buffer) {
    $buffer = replace_insecure_links($buffer);
    return $buffer;
}
function start_buffer(){
    ob_start("filter_buffer");
}

function end_buffer(){
    if (ob_get_length()) ob_end_flush();
}

function replace_insecure_links($str) {

   $str = str_replace ( array("http://www.yoursite.com/", "https://www.yoursite.com/") , array("/", "/"), $str);

   return apply_filters("rsssl_fixer_output", $str);

}

I took part of one plugin, cut it into pieces and make this. It replaced ALL links in my site (menus, css, scripts etc.) and everything was working.

In this example the loop is run every second for ten seconds:

import datetime, time
then = datetime.datetime.now() + datetime.timedelta(seconds=10)
while then > datetime.datetime.now():
    print 'sleeping'
    time.sleep(1)

File file = new File("E:/Responsibility.txt");  
    Scanner scanner = new Scanner(file);
    List<Integer> integers = new ArrayList<>();
    while (scanner.hasNext()) {
        if (scanner.hasNextInt()) {
            integers.add(scanner.nextInt());
        } else {
            scanner.next();
        }
    }
    System.out.println(integers);

Try passing in a Date object instead. I can't see why it doesn't work in the format you have entered:

<script type="text/javascript">
$(function() {               
    $("#birthdate" ).datepicker({
        changeMonth: true,
        changeYear: true,
        yearRange: '1920:2010',
        dateFormat : 'dd-mm-yy',
        defaultDate: new Date(1985, 00, 01)
    });
});
</script>

http://api.jqueryui.com/datepicker/#option-defaultDate

Specify either an actual date via a Date object or as a string in the current dateFormat, or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"

As an extension to @JBNizet's answer for more technical users here's what implementation of org.w3c.dom.Node interface in com.sun.org.apache.xerces.internal.dom.ParentNode looks like, gives you the idea how it actually works.

public void normalize() {
    // No need to normalize if already normalized.
    if (isNormalized()) {
        return;
    }
    if (needsSyncChildren()) {
        synchronizeChildren();
    }
    ChildNode kid;
    for (kid = firstChild; kid != null; kid = kid.nextSibling) {
         kid.normalize();
    }
    isNormalized(true);
}

It traverses all the nodes recursively and calls kid.normalize()
This mechanism is overridden in org.apache.xerces.dom.ElementImpl

public void normalize() {
     // No need to normalize if already normalized.
     if (isNormalized()) {
         return;
     }
     if (needsSyncChildren()) {
         synchronizeChildren();
     }
     ChildNode kid, next;
     for (kid = firstChild; kid != null; kid = next) {
         next = kid.nextSibling;

         // If kid is a text node, we need to check for one of two
         // conditions:
         //   1) There is an adjacent text node
         //   2) There is no adjacent text node, but kid is
         //      an empty text node.
         if ( kid.getNodeType() == Node.TEXT_NODE )
         {
             // If an adjacent text node, merge it with kid
             if ( next!=null && next.getNodeType() == Node.TEXT_NODE )
             {
                 ((Text)kid).appendData(next.getNodeValue());
                 removeChild( next );
                 next = kid; // Don't advance; there might be another.
             }
             else
             {
                 // If kid is empty, remove it
                 if ( kid.getNodeValue() == null || kid.getNodeValue().length() == 0 ) {
                     removeChild( kid );
                 }
             }
         }

         // Otherwise it might be an Element, which is handled recursively
         else if (kid.getNodeType() == Node.ELEMENT_NODE) {
             kid.normalize();
         }
     }

     // We must also normalize all of the attributes
     if ( attributes!=null )
     {
         for( int i=0; i<attributes.getLength(); ++i )
         {
             Node attr = attributes.item(i);
             attr.normalize();
         }
     }

    // changed() will have occurred when the removeChild() was done,
    // so does not have to be reissued.

     isNormalized(true);
 } 

Hope this saves you some time.

My +1 to mata's comment at https://stackoverflow.com/a/10561979/1346705 and to the Nick Craig-Wood's demonstration. You have decoded the string correctly. The problem is with the print command as it converts the Unicode string to the console encoding, and the console is not capable to display the string. Try to write the string into a file and look at the result using some decent editor that supports Unicode:

import codecs

s = '(\xef\xbd\xa1\xef\xbd\xa5\xcf\x89\xef\xbd\xa5\xef\xbd\xa1)\xef\xbe\x89'
s1 = s.decode('utf-8')
f = codecs.open('out.txt', 'w', encoding='utf-8')
f.write(s1)
f.close()

Then you will see (?????)?.

one more variant, but almost the same as Gumbos solution:

var isDebug = function(){
    return window.location.href.search("[?&]debug=") != -1;
};

String formatting, using the new-style .format() method (with the defaults .format() provides):

 '{}{}'.format(s, i)

Or the older, but "still sticking around", %-formatting:

 '%s%d' %(s, i)

In both examples above there's no space between the two items concatenated. If space is needed, it can simply be added in the format strings.

These provide a lot of control and flexibility about how to concatenate items, the space between them etc. For details about format specifications see this.

You can also use http://projectshadowlight.org/jquery-easy-confirm-dialog/ . It's very simple and easy to use. Just include jquery common library and one more file only:

If you use Aptana then you can download a dark color theme! I have been looking for one recently and found the Aptana one. Thought others might be interested!

Check out: http://www.nightlion.net/themes/2009/aptana-dark-color-theme/

try {
    WebElement button = driver.findElement(By.xpath("xpath"));
            button.click();
}
catch(org.openqa.selenium.StaleElementReferenceException ex)
{
    WebElement button = driver.findElement(By.xpath("xpath"));
            button.click();
}

This try/catch code actually worked for me. I got the same stale element error.

I was driving myself crazy with this exact problem. My JSON Marshaller and Unmarshaller were not populating my Go struct. Then I found the solution at https://eager.io/blog/go-and-json:

"As with all structs in Go, it’s important to remember that only fields with a capital first letter are visible to external programs like the JSON Marshaller."

After that, my Marshaller and Unmarshaller worked perfectly!

if you are using redhat,fedora, centos :

sudo yum install pycrypto

for my case I coouldnot install it using pip

No. Unfortunately the Request object is only available until the page finishes loading - once it's complete, you'll lose all values in it unless they've been stored somewhere.

If you want to persist attributes through requests you need to either:

1. Have a hidden input in your form, such as <input type="hidden" name="myhiddenvalue" value="<%= request.getParameter("value") %>" />. This will then be available in the servlet as a request parameter.
2. Put it in the session (see request.getSession() - in a JSP this is available as simply session)

I recommend using the Session as it's easier to manage.

Use the DOM's getElementByid method:

document.getElementById("DATE").value = "your date";

A date can be made with the Date class:

d = new Date();

(Protip: install a javascript console such as in Chrome or Firefox' Firebug extension. It enables you to play with the DOM and Javascript)

There is no specific event for capturing browser close event. But we can detect by the browser positions XY.

<script type="text/javascript">
$(document).ready(function() {
  $(document).mousemove(function(e) {
    if(e.pageY <= 5)
    {
        //this condition would occur when the user brings their cursor on address bar 
        //do something here 
    }
  });
});
</script>

I improved the script from AlexMA for showing my webcam on a web page wich periodically uploads a new image with the same name. I had issues that sometimes the image was flickering because of a broken image or not complete (up)loaded image. To prevent flickering I check the natural height of the image because the size of my webcam image did not change. Only if the loaded image height fits the original image height the full image will be shown on page.

  <h3>Webcam</h3>
  <p align="center">
    <img id="webcam" title="Webcam" onload="updateImage();" src="https://www.your-domain.com/webcam/current.jpg" alt="webcam image" width="900" border="0" />

    <script type="text/javascript" language="JavaScript">

    // off-screen image to preload next image
    var newImage = new Image();
    newImage.src = "https://www.your-domain.com/webcam/current.jpg";

    // remember the image height to prevent showing broken images
    var height = newImage.naturalHeight;

    function updateImage()
    {
        // for sure if the first image was a broken image
        if(newImage.naturalHeight > height)
        {
          height = newImage.naturalHeight;
        }

        // off-screen image loaded and the image was not broken
        if(newImage.complete && newImage.naturalHeight == height) 
        {
          // show the preloaded image on page
          document.getElementById("webcam").src = newImage.src;
        }

        // preload next image with cachebreaker
        newImage.src = "https://www.your-domain.com/webcam/current.jpg?time=" + new Date().getTime();

        // refresh image (set the refresh interval to half of webcam refresh, 
        // in my case the webcam refreshes every 5 seconds)
        setTimeout(updateImage, 2500);
    }

    </script>

A matrix is really just a vector with a dim attribute (for the dimensions). So you can add dimensions to vec using the dim() function and vec will then be a matrix:

vec <- 1:49
dim(vec) <- c(7, 7)  ## (rows, cols)
vec

> vec <- 1:49
> dim(vec) <- c(7, 7)  ## (rows, cols)
> vec
     [,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,]    1    8   15   22   29   36   43
[2,]    2    9   16   23   30   37   44
[3,]    3   10   17   24   31   38   45
[4,]    4   11   18   25   32   39   46
[5,]    5   12   19   26   33   40   47
[6,]    6   13   20   27   34   41   48
[7,]    7   14   21   28   35   42   49

Generally, you can use the func(*tuple) syntax. You can even pass a part of the tuple, which seems like what you're trying to do here:

t = (2010, 10, 2, 11, 4, 0, 2, 41, 0)
dt = datetime.datetime(*t[0:7])

This is called unpacking a tuple, and can be used for other iterables (such as lists) too. Here's another example (from the Python tutorial):

>>> range(3, 6)             # normal call with separate arguments
[3, 4, 5]
>>> args = [3, 6]
>>> range(*args)            # call with arguments unpacked from a list
[3, 4, 5]

Your String-based solution is perfectly OK, there is nothing "un-neat" about it. You have to realize that mathematically, numbers don't have a length, nor do they have digits. Length and digits are both properties of a physical representation of a number in a specific base, i.e. a String.

A logarithm-based solution does (some of) the same things the String-based one does internally, and probably does so (insignificantly) faster because it only produces the length and ignores the digits. But I wouldn't actually consider it clearer in intent - and that's the most important factor.

Note that your initial query is probably not returning what you want:

SELECT availables.bookdate AS Date, DATEDIFF(now(),availables.updated_at) as Age 
FROM availables INNER JOIN rooms ON availables.room_id=rooms.id 
WHERE availables.bookdate BETWEEN  '2009-06-25' AND date_add('2009-06-25', INTERVAL 4 DAY) AND rooms.hostel_id = 5094 GROUP BY availables.bookdate

You are grouping by book date, but you are not using any grouping function on the second column of your query.

The query you are probably looking for is:

SELECT availables.bookdate AS Date, count(*) as subtotal, sum(DATEDIFF(now(),availables.updated_at) as Age)
FROM availables INNER JOIN rooms ON availables.room_id=rooms.id
WHERE availables.bookdate BETWEEN '2009-06-25' AND date_add('2009-06-25', INTERVAL 4 DAY) AND rooms.hostel_id = 5094
GROUP BY availables.bookdate

To be explicit, you can also use --local to use current repository config file:

git config --local user.name "John Doe" 

Alternative built-in: trim()

trim — Strip whitespace (or other characters) from the beginning and end of a string
Description ¶
trim ( string $str [, string $character_mask = " \t\n\r\0\x0B" ] ) : string

This function returns a string with whitespace stripped from the beginning and end of str.
Without the second parameter, trim() will strip these characters:

    " " (ASCII 32 (0x20)), an ordinary space.
    "\t" (ASCII 9 (0x09)), a tab.
    "\n" (ASCII 10 (0x0A)), a new line (line feed).
    "\r" (ASCII 13 (0x0D)), a carriage return.
    "\0" (ASCII 0 (0x00)), the NUL-byte.
    "\x0B" (ASCII 11 (0x0B)), a vertical tab.

It's there to remove line breaks from different kinds of text files, but does not handle html.

The first thing you should do is learn to read error messages. What does it tell you -- that you can't use two strings with the divide operator.

So, ask yourself why they are strings and how do you make them not-strings. They are strings because all input is done via strings. And the way to make then not-strings is to convert them.

One way to convert a string to an integer is to use the int function. For example:

percent = (int(pyc) / int(tpy)) * 100

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

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

   Ex :

   echo $(pwd)/myFile.txt
   

   will be interpreted as

   echo /my/path/myFile.txt
   

   On the other hand ${} expands a variable.

   Ex:

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

   will be interpreted as

   echo toto/myFile.txt
   

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

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

To open the Eye Dropper simply:

1. Open DevTools F12
2. Go to Elements tab
3. Under Styles side bar click on any color preview box

Its main functionality is to inspect pixel color values by clicking them though with its new features you can also see your page's existing colors palette or material design palette by clicking on the two arrows icon at the bottom. It can get quite handy when designing your page.

There are MD5 libraries available for javascript. Keep in mind that this solution will not work if you need to support users who do not have javascript available.

The more common solution is to use HTTPS. With HTTPS, SSL encryption is negotiated between your web server and the client, transparently encrypting all traffic.

For getting Method Name and Class Name try this:

    public static void Call()
    {
        StackTrace stackTrace = new StackTrace();

        var methodName = stackTrace.GetFrame(1).GetMethod();
        var className = methodName.DeclaringType.Name.ToString();

        Console.WriteLine(methodName.Name + "*****" + className );
    }

 mkdir -p `dirname /nosuchdirectory/hi.txt` && cp -r urls-resume /nosuchdirectory/hi.txt

A solution where the logo is truly centered and the links are justified.

The max recommended number of links for the nav is 6, depending on the length of the words in eache link.

If you have 5 links, insert an empty link and style it with:

class="hidden-xs" style="visibility: hidden;"

in this way the number of links is always even.

Any shell has several sets of features.

• The Essential Linux/Unix commands. All of these are available through the subprocess library. This isn't always the best first choice for doing all external commands. Look also at shutil for some commands that are separate Linux commands, but you could probably implement directly in your Python scripts. Another huge batch of Linux commands are in the os library; you can do these more simply in Python.

  And -- bonus! -- more quickly. Each separate Linux command in the shell (with a few exceptions) forks a subprocess. By using Python shutil and os modules, you don't fork a subprocess.

• The shell environment features. This includes stuff that sets a command's environment (current directory and environment variables and what-not). You can easily manage this from Python directly.

• The shell programming features. This is all the process status code checking, the various logic commands (if, while, for, etc.) the test command and all of it's relatives. The function definition stuff. This is all much, much easier in Python. This is one of the huge victories in getting rid of bash and doing it in Python.

• Interaction features. This includes command history and what-not. You don't need this for writing shell scripts. This is only for human interaction, and not for script-writing.

• The shell file management features. This includes redirection and pipelines. This is trickier. Much of this can be done with subprocess. But some things that are easy in the shell are unpleasant in Python. Specifically stuff like (a | b; c ) | something >result. This runs two processes in parallel (with output of a as input to b), followed by a third process. The output from that sequence is run in parallel with something and the output is collected into a file named result. That's just complex to express in any other language.

Specific programs (awk, sed, grep, etc.) can often be rewritten as Python modules. Don't go overboard. Replace what you need and evolve your "grep" module. Don't start out writing a Python module that replaces "grep".

The best thing is that you can do this in steps.

1. Replace AWK and PERL with Python. Leave everything else alone.
2. Look at replacing GREP with Python. This can be a bit more complex, but your version of GREP can be tailored to your processing needs.
3. Look at replacing FIND with Python loops that use os.walk. This is a big win because you don't spawn as many processes.
4. Look at replacing common shell logic (loops, decisions, etc.) with Python scripts.

You could use an onclick event handler in order to get the input value for the text field. Make sure you give the field an unique id attribute so you can refer to it safely through document.getElementById():

If you want to dynamically add elements, you should have a container where to place them. For instance, a <div id="container">. Create new elements by means of document.createElement(), and use appendChild() to append each of them to the container. You might be interested in outputting a meaningful name attribute (e.g. name="member"+i for each of the dynamically generated <input>s if they are to be submitted in a form.

Notice you could also create <br/> elements with document.createElement('br'). If you want to just output some text, you can use document.createTextNode() instead.

Also, if you want to clear the container every time it is about to be populated, you could use hasChildNodes() and removeChild() together.

<html>
<head>
    <script type='text/javascript'>
        function addFields(){
            // Number of inputs to create
            var number = document.getElementById("member").value;
            // Container <div> where dynamic content will be placed
            var container = document.getElementById("container");
            // Clear previous contents of the container
            while (container.hasChildNodes()) {
                container.removeChild(container.lastChild);
            }
            for (i=0;i<number;i++){
                // Append a node with a random text
                container.appendChild(document.createTextNode("Member " + (i+1)));
                // Create an <input> element, set its type and name attributes
                var input = document.createElement("input");
                input.type = "text";
                input.name = "member" + i;
                container.appendChild(input);
                // Append a line break 
                container.appendChild(document.createElement("br"));
            }
        }
    </script>
</head>
<body>
    <input type="text" id="member" name="member" value="">Number of members: (max. 10)<br />
    <a href="#" id="filldetails" onclick="addFields()">Fill Details</a>
    <div id="container"/>
</body>
</html>

I hope I can help someone with this info as well: I moved my service class into another package and I fixed the references. The project was perfectly fine, BUT the service class could not be found by the activity.

By watching the log in logcat I noticed the warning about the issue: the activity could not find the service class, but the funny thing was that the package was incorrect, it contained a "/" char. The compiler was looking for

com.something./service.MyService

instead of

com.something.service.MyService

I moved the service class out from the package and back in and everything worked just fine.

Install Node.js to fix it permanently for all projects.

Chaos is spot on, though for these sorts of questions you should check out the Jquery Documentation online - it really is quite comprehensive. The feature you are after is called 'jquery selectors'

Generally you do $('#ID').val() - the .afterwards can do a number of things on the element that is returned from the selector. You can also select all of the elements on a certain class and do something to each of them. Check out the documentation for some good examples.

Using an absolute or relative string as the filename.

name_of_file = input("What is the name of the file: ")
completeName = '/home/user/Documents'+ name_of_file + ".txt"
file1 = open(completeName , "w")
toFile = input("Write what you want into the field")
file1.write(toFile)
file1.close()

On your own system, try

install.packages("foo", dependencies=...)

with the dependencies= argument is documented as

dependencies: logical indicating to also install uninstalled packages
      which these packages depend on/link to/import/suggest (and so
      on recursively).  Not used if ‘repos = NULL’.  Can also be a
      character vector, a subset of ‘c("Depends", "Imports",
      "LinkingTo", "Suggests", "Enhances")’.

      Only supported if ‘lib’ is of length one (or missing), so it
      is unambiguous where to install the dependent packages.  If
      this is not the case it is ignored, with a warning.

      The default, ‘NA’, means ‘c("Depends", "Imports",
      "LinkingTo")’.

      ‘TRUE’ means (as from R 2.15.0) to use ‘c("Depends",
      "Imports", "LinkingTo", "Suggests")’ for ‘pkgs’ and
      ‘c("Depends", "Imports", "LinkingTo")’ for added
      dependencies: this installs all the packages needed to run
      ‘pkgs’, their examples, tests and vignettes (if the package
      author specified them correctly).

so you probably want a value TRUE.

In your package, list what is needed in Depends:, see the Writing R Extensions manual which is pretty clear on this.

You cannot change a table while the INSERT trigger is firing. The INSERT might do some locking which could result in a deadlock. Also, updating the table from a trigger would then cause the same trigger to fire again in an infinite recursive loop. Both of these reasons are why MySQL prevents you from doing this.

However, depending on what you're trying to achieve, you can access the new values by using NEW.fieldname or even the old values--if doing an UPDATE--with OLD.

If you had a row named full_brand_name and you wanted to use the first two letters as a short name in the field small_name you could use:

CREATE TRIGGER `capital` BEFORE INSERT ON `brandnames`
FOR EACH ROW BEGIN
  SET NEW.short_name = CONCAT(UCASE(LEFT(NEW.full_name,1)) , LCASE(SUBSTRING(NEW.full_name,2)))
END

The proper way to remove a cookie is to set the max age to 0 and add the cookie back to the HttpServletResponse object.

Most people don't realize or forget to add the cookie back onto the response object. By doing that it will expire and remove the cookie immediately.

...retrieve cookie from HttpServletRequest
cookie.setMaxAge(0);
response.addCookie(cookie);

I use this mnemonic:

• Single quotes are for strings (one thing)
• Double quotes are for tables names and column names (two things)

This is not 100% correct according to the specs, but this mnemonic helps me (human being).

If you are needing this to get user's home dir, below could be considered as portable (win32 and linux at least), part of a standard library.

>>> os.path.expanduser('~')
'C:\\Documents and Settings\\johnsmith'

Also you could parse such string to get only last path component (ie. user name).

See: os.path.expanduser

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

Is your problem similar to this:

l = [[0]] * 4
l[0][0] += 1
print l # prints "[[1], [1], [1], [1]]"

If so, you simply need to copy the objects when you store them:

import copy
l = [copy.copy(x) for x in [[0]] * 4]
l[0][0] += 1
print l # prints "[[1], [0], [0], [0]]"

The objects in question should implement a __copy__ method to copy objects. See the documentation for copy. You may also be interested in copy.deepcopy, which is there as well.

EDIT: Here's the problem:

arrayList = []
for x in allValues:
    result = model(x)
    arrayList.append(wM) # appends the wM object to the list
    wM.reset()           # clears  the wM object

You need to append a copy:

import copy
arrayList = []
for x in allValues:
    result = model(x)
    arrayList.append(copy.copy(wM)) # appends a copy to the list
    wM.reset()                      # clears the wM object

But I'm still confused as to where wM is coming from. Won't you just be copying the same wM object over and over, except clearing it after the first time so all the rest will be empty? Or does model() modify the wM (which sounds like a terrible design flaw to me)? And why are you throwing away result?

I think the only cookie you need is JSESSIONID=xxx..

Also NEVER share your cookies, becasuse someone may access your personal data that way. Specially when the cookies are session. These cookies will stop working once you logout the site.

You need to use:

await client.PostAsync(uri, content);

Something like that:

var comment = "hello world";
var questionId = 1;

var formContent = new FormUrlEncodedContent(new[]
{
    new KeyValuePair<string, string>("comment", comment), 
    new KeyValuePair<string, string>("questionId", questionId) 
});

var myHttpClient = new HttpClient();
var response = await myHttpClient.PostAsync(uri.ToString(), formContent);

And if you need to get the response after post, you should use:

var stringContent = await response.Content.ReadAsStringAsync();

Hope it helps ;)

This statement was added in MySQL 5.1.7 but was found to be dangerous and was removed in MySQL 5.1.23. It was intended to enable upgrading pre-5.1 databases to use the encoding implemented in 5.1 for mapping database names to database directory names. However, use of this statement could result in loss of database contents, which is why it was removed. Do not use RENAME DATABASE in earlier versions in which it is present.

To perform the task of upgrading database names with the new encoding, use ALTER DATABASE db_name UPGRADE DATA DIRECTORY NAME instead: http://dev.mysql.com/doc/refman/5.1/en/alter-database.html

Use git push origin master instead.

You have a repository locally and the initial git push is "pushing" to it. It's not necessary to do so (as it is local) and it shows everything as up-to-date. git push origin master specifies a a remote repository (origin) and the branch located there (master).

For more information, check out this resource.

Just create an empty __init__.py file and add it in root as well as all the sub directory/folder of your python application where you have other python modules. See https://docs.python.org/3/tutorial/modules.html#packages

Compress your .sql file, and make sure to name it .[format].[compression], i.e. database.sql.zip.

As noted above, PhpMyAdmin throws this error if your .sql file is larger than the Maximum allowed upload size -- but, in my case the maximum was 50MiB despite that I had set all options noted in previous answers (look for the "Max: 50MiB" next to the upload button in PhpMyAdmin).

The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5. From the comment you put this needed to be declared elsewhere in your code

$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider

The error was because you are trying to execute a method that does not exist.

PS C:\Users\Matt> $md5 | gm

The .ComputeHash() of $md5.ComputeHash() was the null valued expression. Typing in gibberish would create the same effect.

PowerShell by default allows this to happen as defined its StrictMode

When Set-StrictMode is off, uninitialized variables (Version 1) are assumed to have a value of 0 (zero) or $Null, depending on type. References to non-existent properties return $Null, and the results of function syntax that is not valid vary with the error. Unnamed variables are not permitted.

You can see your current session settings by querying nls_session_parameters:

select value
from nls_session_parameters
where parameter = 'NLS_NUMERIC_CHARACTERS';

VALUE                                  
----------------------------------------
.,                                       

That may differ from the database defaults, which you can see in nls_database_parameters.

In this session your query errors:

select to_number('100,12') from dual;

Error report -
SQL Error: ORA-01722: invalid number
01722. 00000 -  "invalid number"

I could alter my session, either directly with alter session or by ensuring my client is configured in a way that leads to the setting the string needs (it may be inherited from a operating system or Java locale, for example):

alter session set NLS_NUMERIC_CHARACTERS = ',.';
select to_number('100,12') from dual;

TO_NUMBER('100,12')
-------------------
             100,12 

In SQL Developer you can set your preferred value in Tool->Preferences->Database->NLS.

But I can also override that session setting as part of the query, with the optional third nlsparam parameter to to_number(); though that makes the optional second fmt parameter necessary as well, so you'd need to be able pick a suitable format:

alter session set NLS_NUMERIC_CHARACTERS = '.,';
select to_number('100,12', '99999D99', 'NLS_NUMERIC_CHARACTERS='',.''')
from dual;

TO_NUMBER('100,12','99999D99','NLS_NUMERIC_CHARACTERS='',.''')
--------------------------------------------------------------
                                                        100.12 

By default the result is still displayed with my session settings, so the decimal separator is still a period.

This function uses the current millisecond time to subtract the current week, and then subtracts one more week if the current date is on a monday (javascript counts from sunday).

function getMonday(fromDate) {
    // length of one day i milliseconds
  var dayLength = 24 * 60 * 60 * 1000;

  // Get the current date (without time)
    var currentDate = new Date(fromDate.getFullYear(), fromDate.getMonth(), fromDate.getDate());

  // Get the current date's millisecond for this week
  var currentWeekDayMillisecond = ((currentDate.getDay()) * dayLength);

  // subtract the current date with the current date's millisecond for this week
  var monday = new Date(currentDate.getTime() - currentWeekDayMillisecond + dayLength);

  if (monday > currentDate) {
    // It is sunday, so we need to go back further
    monday = new Date(monday.getTime() - (dayLength * 7));
  }

  return monday;
}

I have tested it when week spans over from one month to another (and also years), and it seems to work properly.

While accepted answer is pretty complete (I used myself in similar question that arised to me), I think it is worth to put the whole supported language codes and variations, as well as encodings, and point user to a file which is present in almost any linux distributions, in case he simply wants a quicker answer and no internet for example.

The ? is to allow Parameterized Query. These parameterized query is to allow type-specific value when replacing the ? with their respective value.

That's all to it.

Here's a reason of why it's better to use Parameterized Query. Basically, it's easier to read and debug.

The traditional for loop in Objective-C is inherited from standard C and takes the following form:

for (/* Instantiate local variables*/ ; /* Condition to keep looping. */ ; /* End of loop expressions */)
{
    // Do something.
}

For example, to print the numbers from 1 to 10, you could use the for loop:

for (int i = 1; i <= 10; i++)
{
    NSLog(@"%d", i);
}

On the other hand, the for in loop was introduced in Objective-C 2.0, and is used to loop through objects in a collection, such as an NSArray instance. For example, to loop through a collection of NSString objects in an NSArray and print them all out, you could use the following format.

for (NSString* currentString in myArrayOfStrings)
{
    NSLog(@"%@", currentString);
}

This is logically equivilant to the following traditional for loop:

for (int i = 0; i < [myArrayOfStrings count]; i++)
{
    NSLog(@"%@", [myArrayOfStrings objectAtIndex:i]);
}

The advantage of using the for in loop is firstly that it's a lot cleaner code to look at. Secondly, the Objective-C compiler can optimize the for in loop so as the code runs faster than doing the same thing with a traditional for loop.

Hope this helps.

Note: ||= does not exist. (logical or) You can use

y= y || expr; // expr is NOT evaluated if y==true

or

y = expr ? true : y;  // expr is always evaluated.

Building on Mark Byers's answer.

The 3rd project could be a WCF project, hosted as a Windows Service. If all programs listened to that service, one application could call the service. The service passes the message on to all listening clients and they can perform an action if suitable.

psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

I searching the solution for a while. So, this one fixed the issue for me as well (reinit db):

rm -r /usr/local/var/postgres  
initdb /usr/local/var/postgres -E utf8  
pg_ctl -D /usr/local/var/postgres -l logfile start

I use OS X 10.11.3 with brew.

Arkaitz is correct that string is a managed type. What this means for you is that you never have to worry about how long the string is, nor do you have to worry about freeing or reallocating the memory of the string.

On the other hand, the char[] notation in the case above has restricted the character buffer to exactly 256 characters. If you tried to write more than 256 characters into that buffer, at best you will overwrite other memory that your program "owns". At worst, you will try to overwrite memory that you do not own, and your OS will kill your program on the spot.

Bottom line? Strings are a lot more programmer friendly, char[]s are a lot more efficient for the computer.

What I need is a function which prints an object (obj), but only if global variable verbose is true, else it does nothing.

I want to be able to change the global parameter "verbose" at any time. Simplicity and readability to me are of paramount importance. So I would proceed as the following lines indicate:

ak@HP2000:~$ python3
Python 3.4.3 (default, Oct 14 2015, 20:28:29) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> verbose = True
>>> def vprint(obj):
...     if verbose:
...         print(obj)
...     return
... 
>>> vprint('Norm and I')
Norm and I
>>> verbose = False
>>> vprint('I and Norm')
>>> 

Global variable "verbose" can be set from the parameter list, too.

I think you should move the variable declaration to top of block. I.e.

{
    foo();
    int i = 0;
    bar();
}

to

{
    int i = 0;
    foo();
    bar();
}

If you want to clean up the whole form, you can use such approach. This is your model into controller:

    $scope.registrationForm = {
    'firstName'     : '',
    'lastName'      : ''
};

Your HTML:

<form class="form-horizontal" name="registrForm" role="form">
   <input type="text" class="form-control"
                       name="firstName"
                       id="firstName"
                       ng-model="registrationForm.firstName"
                       placeholder="First name"
                       required> First name
   <input type="text" class="form-control"
                       name="lastName"
                       id="lastName"
                       ng-model="registrationForm.lastName"
                       placeholder="Last name"
                       required> Last name
</form>

Then, you should clone/save your clear state by:

$scope.originForm = angular.copy($scope.registrationForm);

Your reset function will be:

$scope.resetForm = function(){
    $scope.registrationForm = angular.copy($scope.originForm); // Assign clear state to modified form 
    $scope.registrForm.$setPristine(); // this line will update status of your form, but will not clean your data, where `registrForm` - name of form.
};

In such way you are able to clean up the whole your form

CSS solutions not working properly on touch device

I found that any CSS solutions made the menu stay open on touch devices, they didn't collapse anymore.

So I read the article: https://www.brianshim.com/webtricks/drop-down-menus-on-ios-and-android/ (by Brian Shim)
Very useful! It states that a touch device always first checks the existence of a hover class on an element.

But: by using jQuery .show() you introduce a style attribute (display:block;) that makes the menu open up on first touch. Now the menu has opened without the bootstrap 'show' class. If a user chooses a link from the dropdown menu it works perfectly. But if a user decides to close the menu without using it he has to tap twice to close the menu: At the first tap the original bootstrap 'show' class gets attached so the menu opens up again, at the second tap the menu closes due to normal bootstrap behaviour (removal of 'show' class).

To prevent this I used the article: https://codeburst.io/the-only-way-to-detect-touch-with-javascript-7791a3346685 (by David Gilbertson)

He has some very handy ways of detecting touch or hover devices.

So, combined the two authors with a bit jQuery of my own:

$(window).one('mouseover', function(){
      window.USER_CAN_HOVER = true;
      if(USER_CAN_HOVER){
          jQuery('#navbarNavDropdown ul li.dropdown').on("mouseover", function() {
             var $parent = jQuery(this);
             var $dropdown = $parent.children('ul');

             $dropdown.show(200,function() { 
               $parent.mouseleave(function() {
                 var $this = jQuery(this);
                 $this.children('ul').fadeOut(200);
               });
             });
          });
      };

}); Check once if a device allows a hover event. If it does, introduce the possibility to hover using .show(). If the device doesn't allow a hover event, the .show() never gets introduced so you get natural bootstrap behaviour on touch device.

Be sure to remove any CSS regarding menu hover classes.

Took me three days :) so I hope it helps some of you.

If you want to iterate over all the values:

dict.values.forEach { value in
    // print(value)
}

Not a single answer here actually answers the question. The OP did not ask about a singleton/per-application DbContext design, he asked about a per-(web)request design and what potential benefits could exist.

I'll reference http://mehdi.me/ambient-dbcontext-in-ef6/ as Mehdi is a fantastic resource:

Possible performance gains.

Each DbContext instance maintains a first-level cache of all the entities its loads from the database. Whenever you query an entity by its primary key, the DbContext will first attempt to retrieve it from its first-level cache before defaulting to querying it from the database. Depending on your data query pattern, re-using the same DbContext across multiple sequential business transactions may result in a fewer database queries being made thanks to the DbContext first-level cache.

It enables lazy-loading.

If your services return persistent entities (as opposed to returning view models or other sorts of DTOs) and you'd like to take advantage of lazy-loading on those entities, the lifetime of the DbContext instance from which those entities were retrieved must extend beyond the scope of the business transaction. If the service method disposed the DbContext instance it used before returning, any attempt to lazy-load properties on the returned entities would fail (whether or not using lazy-loading is a good idea is a different debate altogether which we won't get into here). In our web application example, lazy-loading would typically be used in controller action methods on entities returned by a separate service layer. In that case, the DbContext instance that was used by the service method to load these entities would need to remain alive for the duration of the web request (or at the very least until the action method has completed).

Keep in mind there are cons as well. That link contains many other resources to read on the subject.

Just posting this in case someone else stumbles upon this question and doesn't get absorbed in answers that don't actually address the question.

Depending on the Eclipse in question the required WTP packages may be found with different names. For example in Eclipse Luna I found it easiest to search with "Tools" and choose one that mentioned Tools for Java EE development. That added the project facet functionality. Searching with "WTP" wasn't of much help.

Good technical & logical question my dear friend. No in robots.txt file you can't go with relative URL of the sitemap; you need to go with the complete URL of the sitemap.

It's better to go with "sitemap: https://www.example.com/sitemap_index.xml"

Yes. 'Z' stands for Zulu time, which is also GMT and UTC.

From http://en.wikipedia.org/wiki/Coordinated_Universal_Time:

The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950. The letter also refers to the "zone description" of zero hours, which has been used since 1920 (see time zone history). Since the NATO phonetic alphabet and amateur radio word for Z is "Zulu", UTC is sometimes known as Zulu time.

Technically, because the definition of nautical time zones is based on longitudinal position, the Z time is not exactly identical to the actual GMT time 'zone'. However, since it is primarily used as a reference time, it doesn't matter what area of Earth it applies to as long as everyone uses the same reference.

From wikipedia again, http://en.wikipedia.org/wiki/Nautical_time:

Around 1950, a letter suffix was added to the zone description, assigning Z to the zero zone, and A–M (except J) to the east and N–Y to the west (J may be assigned to local time in non-nautical applications; zones M and Y have the same clock time but differ by 24 hours: a full day). These were to be vocalized using a phonetic alphabet which pronounces the letter Z as Zulu, leading sometimes to the use of the term "Zulu Time". The Greenwich time zone runs from 7.5°W to 7.5°E longitude, while zone A runs from 7.5°E to 22.5°E longitude, etc.

You could either explicitly name the columns you want to keep, like so:

keep = [a.id, a.julian_date, a.user_id, b.quan_created_money, b.quan_created_cnt]

Or in a more general approach you'd include all columns except for a specific one via a list comprehension. For example like this (excluding the id column from b):

keep = [a[c] for c in a.columns] + [b[c] for c in b.columns if c != 'id']

Finally you make a selection on your join result:

d = a.join(b, a.id==b.id, 'outer').select(*keep)

This might be simplest way -

Collections.sort(listOfStudent,new Comparator<Student>(){
                     public int compare(Student s1,Student s2){
                           // Write your logic here.
                     }});

Using Java 8(lambda expression) -

listOfStudent.sort((s1, s2) -> s1.age - s2.age); 

As others have pointed out, string is always nullable in C#. I suspect you are asking the question because you are not able to leave the middle name as null or blank? I suspect the problem is with your validation attributes, most likely the RegEx. I'm not able to fully parse RegEx in my head but I think your RegEx insists on the first character being present. I could be wrong - RegEx is hard. In any case, try commenting out your validation attributes and see if it works, then add them back in one at a time.

Try this

select to_char(SYSDATE,'Month') from dual;

for full name and try this

select to_char(SYSDATE,'Mon') from dual;

for abbreviation

The new ECMAScript module support is able natively in Node.js 12

It was released on 2019-04-23 and it means there is no need to use the flag --experimental-modules.

The new ECMAScript module support in Node.js 12

Assuming that create and destroy are free functions (which seems to be the case from the OP's code snippet) with the following signatures:

Bar* create();
void destroy(Bar*);

You can write your class Foo like this

class Foo {

    std::unique_ptr<Bar, void(*)(Bar*)> ptr_;

    // ...

public:

    Foo() : ptr_(create(), destroy) { /* ... */ }

    // ...
};

Notice that you don't need to write any lambda or custom deleter here because destroy is already a deleter.

Note that in general, Mockito does allow throwing checked exceptions so long as the exception is declared in the message signature. For instance, given

class BarException extends Exception {
  // this is a checked exception
}

interface Foo {
  Bar frob() throws BarException
}

it's legal to write:

Foo foo = mock(Foo.class);
when(foo.frob()).thenThrow(BarException.class)

However, if you throw a checked exception not declared in the method signature, e.g.

class QuxException extends Exception {
  // a different checked exception
}

Foo foo = mock(Foo.class);
when(foo.frob()).thenThrow(QuxException.class)

Mockito will fail at runtime with the somewhat misleading, generic message:

Checked exception is invalid for this method!
Invalid: QuxException

This may lead you to believe that checked exceptions in general are unsupported, but in fact Mockito is only trying to tell you that this checked exception isn't valid for this method.

Posting answer to my own question as I found it here and was hidden in bottom somewhere -

https://social.msdn.microsoft.com/Forums/vstudio/en-US/64baed8c-b00c-40d5-b19a-99b26a11516e/visual-c-redistributable-for-visual-studio-2015-rc-fails-on-windows-server-2012?forum=vssetup

This is because the OS failed to install the required update Windows8.1-KB2999226-x64.msu.

However, you can install it by extracting that update to a folder (e.g. XXXX), and execute following cmdlet. You can find the Windows8.1-KB2999226-x64.msu at below.

C:\ProgramData\Package Cache\469A82B09E217DDCF849181A586DF1C97C0C5C85\packages\Patch\amd64\Windows8.1-KB2999226-x64.msu

copy this file to a folder you like, and

Create a folder XXXX in that and execute following commands from Admin command propmt

wusa.exe Windows8.1-KB2999226-x64.msu /extract:XXXX

DISM.exe /Online /Add-Package /PackagePath:XXXX\Windows8.1-KB2999226-x64.cab

vc_redist.x64.exe /repair

(last command need not be run. Just execute vc_redist.x64.exe once again)

this worked for me.

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

Unless you need a custom date and time format, it's easier, less error-prone, and more readable to use one of the built-in date time format constants:

echo date(DATE_RFC822, 1368496604);

Although the previous answers work perfectly, I will just add another way where the elements can also be classified using the interface they have implemented.

Refer W3 Org for available interfaces

console.log(document.querySelector("#anchorelem") instanceof HTMLAnchorElement);_x000D_
console.log(document.querySelector("#divelem") instanceof HTMLDivElement);_x000D_
console.log(document.querySelector("#buttonelem") instanceof HTMLButtonElement);_x000D_
console.log(document.querySelector("#inputelem") instanceof HTMLInputElement);

<a id="anchorelem" href="">Anchor element</a>_x000D_
<div id="divelem">Div Element</div>_x000D_
<button id="buttonelem">Button Element</button>_x000D_
<br><input id="inputelem">

The interface check can be made in 2 ways as elem instanceof HTMLAnchorElement or elem.constructor.name == "HTMLAnchorElement", both returns true

The same error occurs also when doing SELECT DISTINCT ..., <CLOB_column>, ....

If this CLOB column contains values shorter than limit for VARCHAR2 in all the applicable rows you may use to_char(<CLOB_column>) or concatenate results of multiple calls to DBMS_LOB.SUBSTR(<CLOB_column>, ...).

grep was born to extract things:

grep -Po 'name="\K[^"]*'

test with your data:

kent$  echo '<parameter name="PortMappingEnabled" access="readWrite" type="xsd:boolean"></parameter>
  <parameter name="PortMappingLeaseDuration" access="readWrite" activeNotify="canDeny" type="xsd:unsignedInt"></parameter>
  <parameter name="RemoteHost" access="readWrite"></parameter>
  <parameter name="ExternalPort" access="readWrite" type="xsd:unsignedInt"></parameter>
  <parameter name="ExternalPortEndRange" access="readWrite" type="xsd:unsignedInt"></parameter>
  <parameter name="InternalPort" access="readWrite" type="xsd:unsignedInt"></parameter>
  <parameter name="PortMappingProtocol" access="readWrite"></parameter>
  <parameter name="InternalClient" access="readWrite"></parameter>
  <parameter name="PortMappingDescription" access="readWrite"></parameter>
'|grep -Po 'name="\K[^"]*'
PortMappingEnabled
PortMappingLeaseDuration
RemoteHost
ExternalPort
ExternalPortEndRange
InternalPort
PortMappingProtocol
InternalClient
PortMappingDescription

You do the same way as any other character matching, but you use \uXXXX where XXXX is the unicode number of the character.

In my case with High Sierra, apart from the eclipse folder, I deleted also:

• ~/.eclipse
• ~/.p2/pool/plugins/org.eclipse.*
• ~/.p2/pool/.eclipseextension/
• ~/.p2/org.eclipse.equinox.p2.repository/
• ~/.p2/org.eclipse.equinox.p2.engine/
• ~/.p2/org.eclipse.equinox.p2.core/

Or simply

add to your element

[ngStyle]="{'color': myVariableColor}"

eg

<mat-icon [ngStyle]="{'color': myVariableColor}">{{ getActivityIcon() }}</mat-icon>

Where color can be defined at another component etc

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

I know that this is a quite old thread, but here is an updated version for Integers and Java 8:

Arrays.sort(array, (o1, o2) -> o2 - o1);

Note that it is "o1 - o2" for the normal ascending order (or Comparator.comparingInt()).

This also works for any other kinds of Objects. Say:

Arrays.sort(array, (o1, o2) -> o2.getValue() - o1.getValue());

Using LIKE:

SELECT *
  FROM TABLE
 WHERE column LIKE '%cats%'  --case-insensitive

If you need this solution for only few types of modals just use style="width:90%" attribute.

example:

div class="modal-dialog modal-lg" style="width:90%"

note: this will change only this particular modal

If you're simply trying to resize an image, I'd recommend setting width and height of the image with CSS. Here's a quick example:

.small-image {
    width: 100px;
    height: 100px;
}

Note that the height and width can also be set using JavaScript. Here's quick code sample:

var img = document.getElement("my-image");
img.style.width = 100 + "px";  // Make sure you add the "px" to the end,
img.style.height = 100 + "px"; // otherwise you'll confuse IE

Also, to ensure that the resized image looks good, add the following css rules to image selector:

• -ms-interpolation-mode: bicubic: introduce in IE7
• image-rendering: optimizeQuality: introduced in FireFox 3.6

As far as I can tell, all browsers except IE using an bicubic algorithm to resize images by default, so your resized images should look good in Firefox and Chrome.

If setting the css width and height doesn't work, you may want to play with a css transform:

• -moz-transform: scale(sx[, sy])
• -webkit-transform:scale(sx[, sy])

If for whatever reason you need to use a canvas, please note that there are two ways an image can be resize: by resizing the canvas with css or by drawing the image at a smaller size.

See this question for more details.

To allow user ec2-user (Amazon AWS) write access to the public web directory (/var/www/html),
enter this command via Putty or Terminal, as the root user sudo:

chown -R ec2-user /var/www/html

Make sure permissions on that entire folder were correct:

chmod -R 755 /var/www/html

In my use case, I parameterized some fields in an HTML document, and once I load these fields I match and replace them using the str_replace method.

<?php echo str_replace(array("{{client_name}}", "{{client_testing}}"), array('client_company_name', 'test'), 'html_document'); ?>

With the help of raincoat's code on GitHub, I managed to get a running version accessing the clipboard with plain JavaScript.

function TrelloClipboard() {
    var me = this;

    var utils = {
        nodeName: function (node, name) {
            return !!(node.nodeName.toLowerCase() === name)
        }
    }
    var textareaId = 'simulate-trello-clipboard',
        containerId = textareaId + '-container',
        container, textarea

    var createTextarea = function () {
        container = document.querySelector('#' + containerId)
        if (!container) {
            container = document.createElement('div')
            container.id = containerId
            container.setAttribute('style', [, 'position: fixed;', 'left: 0px;', 'top: 0px;', 'width: 0px;', 'height: 0px;', 'z-index: 100;', 'opacity: 0;'].join(''))
            document.body.appendChild(container)
        }
        container.style.display = 'block'
        textarea = document.createElement('textarea')
        textarea.setAttribute('style', [, 'width: 1px;', 'height: 1px;', 'padding: 0px;'].join(''))
        textarea.id = textareaId
        container.innerHTML = ''
        container.appendChild(textarea)

        textarea.appendChild(document.createTextNode(me.value))
        textarea.focus()
        textarea.select()
    }

    var keyDownMonitor = function (e) {
        var code = e.keyCode || e.which;
        if (!(e.ctrlKey || e.metaKey)) {
            return
        }
        var target = e.target
        if (utils.nodeName(target, 'textarea') || utils.nodeName(target, 'input')) {
            return
        }
        if (window.getSelection && window.getSelection() && window.getSelection().toString()) {
            return
        }
        if (document.selection && document.selection.createRange().text) {
            return
        }
        setTimeout(createTextarea, 0)
    }

    var keyUpMonitor = function (e) {
        var code = e.keyCode || e.which;
        if (e.target.id !== textareaId || code !== 67) {
            return
        }
        container.style.display = 'none'
    }

    document.addEventListener('keydown', keyDownMonitor)
    document.addEventListener('keyup', keyUpMonitor)
}

TrelloClipboard.prototype.setValue = function (value) {
    this.value = value;
}

var clip = new TrelloClipboard();

Bookmarking this URL should give you a full-screen compose window, without any distractions:

https://mail.google.com/mail/?view=cm&fs=1&tf=1

Additionally, if you want to be future-proof (see for instance how other URLs in this question stopped working) you can bookmark a link to:

mailto:

It will open your default email client and you probably already have Gmail configured for that purpose.

Why not just simplify it to if($_GET['id']). It will return true or false depending on status of the parameter's existence.

It looks like you're trying to scale the background image? There's a great article in the reference bellow where you can use css3 to achieve this.

And if I miss-read the question then I humbly accept the votes down. (Still good to know though)

Please consider the following code:

#some_div_or_body { 
   background: url(images/bg.jpg) no-repeat center center fixed; 
   -webkit-background-size: cover;
   -moz-background-size: cover;
   -o-background-size: cover;
   background-size: cover;
}

This will work on all major browsers, of course it doesn't come easy on IE. There are some workarounds however such as using Microsoft's filters:

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='.myBackground.jpg', sizingMethod='scale');
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='myBackground.jpg', sizingMethod='scale')";

There are some alternatives that can be used with a little bit peace of mind by using jQuery:

HTML

<img src="images/bg.jpg" id="bg" alt="">

CSS

#bg { position: fixed; top: 0; left: 0; }
.bgwidth { width: 100%; }
.bgheight { height: 100%; }

jQuery:

 $(window).load(function() {    

var theWindow        = $(window),
    $bg              = $("#bg"),
    aspectRatio      = $bg.width() / $bg.height();

function resizeBg() {

    if ( (theWindow.width() / theWindow.height()) < aspectRatio ) {
        $bg
            .removeClass()
            .addClass('bgheight');
    } else {
        $bg
            .removeClass()
            .addClass('bgwidth');
    }

}

theWindow.resize(resizeBg).trigger("resize");

});

I hope this helps!

Use numpy.asscalar to convert a numpy array / matrix a scalar value:

>>> a=numpy.array([[[[42]]]])
>>> numpy.asscalar(a)
42

The output data type is the same type returned by the input’s item method.

It has built in error-checking if there is more than an single element:

>>> a=numpy.array([1, 2])
>>> numpy.asscalar(a)

gives:

ValueError: can only convert an array of size 1 to a Python scalar

Note: the object passed to asscalar must respond to item, so passing a list or tuple won't work.

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

First open Visual studio ..select your project in solution explorer..Right click and choose option "browse with" then set IE as default browser.

Now open IE ..go to
Tools >> Internet option >> Advance>> uncheck the checkbox having "Disable Script Debugging (Internet Explorer). and then click Apply and OK and you are done ..

Now you can set breakpoints in your JS file and then hit the debug button in VS..

EDIT:- For asp.net web application right click on the page which is your startup page(say default.aspx) and perform the same steps. :)

It's impossible. document.cookie contains information in string like this:

key1=value1;key2=value2;...

So there isn't any information about dates.

You can store these dates in separate cookie variable:

auth_user=Riateche;auth_expire=01/01/2012

But user can change this variable.

If you have UTF8, use this (actually works with SVG source), like:

btoa(unescape(encodeURIComponent(str)))

example:

 var imgsrc = 'data:image/svg+xml;base64,' + btoa(unescape(encodeURIComponent(markup)));
 var img = new Image(1, 1); // width, height values are optional params 
 img.src = imgsrc;

If you need to decode that base64, use this:

var str2 = decodeURIComponent(escape(window.atob(b64)));
console.log(str2);

Example:

var str = "äöüÄÖÜçéèñ";
var b64 = window.btoa(unescape(encodeURIComponent(str)))
console.log(b64);

var str2 = decodeURIComponent(escape(window.atob(b64)));
console.log(str2);

Note: if you need to get this to work in mobile-safari, you might need to strip all the white-space from the base64 data...

function b64_to_utf8( str ) {
    str = str.replace(/\s/g, '');    
    return decodeURIComponent(escape(window.atob( str )));
}

2017 Update

This problem has been bugging me again.
The simple truth is, atob doesn't really handle UTF8-strings - it's ASCII only.
Also, I wouldn't use bloatware like js-base64.

• For any character equal to or below 127 (hex 0x7F), the UTF-8 representation is one byte. It is just the lowest 7 bits of the full unicode value. This is also the same as the ASCII value.

• For characters equal to or below 2047 (hex 0x07FF), the UTF-8 representation is spread across two bytes. The first byte will have the two high bits set and the third bit clear (i.e. 0xC2 to 0xDF). The second byte will have the top bit set and the second bit clear (i.e. 0x80 to 0xBF).

• For all characters equal to or greater than 2048 but less that 65535 (0xFFFF), the UTF-8 representation is spread across three bytes.

I did the Following in Kotlin

1. Create Application Class

2. Edit the Application Class as Follows

   class FTApplication: MultiDexApplication() {
   override fun attachBaseContext(base: Context?) {
       super.attachBaseContext(base)
       MultiDex.install(this)
   }
   
   init {
       instance = this
   }
   
   val mFTActivityLifecycleCallbacks = FTActivityLifecycleCallbacks()
   
   override fun onCreate() {
       super.onCreate()
   
       registerActivityLifecycleCallbacks(mFTActivityLifecycleCallbacks)
   }
   
   companion object {
       private var instance: FTApplication? = null
   
       fun currentActivity(): Activity? {
   
           return instance!!.mFTActivityLifecycleCallbacks.currentActivity
       }
   }
   
    }
   

3. Create the ActivityLifecycleCallbacks class

   class FTActivityLifecycleCallbacks: Application.ActivityLifecycleCallbacks {
   
   var currentActivity: Activity? = null
   
   override fun onActivityPaused(activity: Activity?) {
       currentActivity = activity
   }
   
   override fun onActivityResumed(activity: Activity?) {
       currentActivity = activity
   }
   
   override fun onActivityStarted(activity: Activity?) {
       currentActivity = activity
   }
   
   override fun onActivityDestroyed(activity: Activity?) {
   }
   
   override fun onActivitySaveInstanceState(activity: Activity?, outState: Bundle?) {
   }
   
   override fun onActivityStopped(activity: Activity?) {
   }
   
   override fun onActivityCreated(activity: Activity?, savedInstanceState: Bundle?) {
       currentActivity = activity
   }
   
   }
   

4. you can now use it in any class by calling the following: FTApplication.currentActivity()

Answer:

git reset HEAD path/to/file

//You could place this code into viewDidLoad
- (void)viewDidLoad
{
    [super viewDidLoad];
    self.navigationController.navigationBar.tintColor = [UIColor redColor];
    //change the nav bar colour
    self.navigationController.view.backgroundColor = [UIColor redColor];
    //change the background colour
    self.navigationController.navigationBar.translucent = NO;
 }   
//Or you can place it into viewDidAppear
- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:(BOOL)animated];
    self.navigationController.navigationBar.tintColor = [UIColor redColor];
    //change the nav bar colour
    self.navigationController.view.backgroundColor = [UIColor redColor];
    //change the background colour
    self.navigationController.navigationBar.translucent = NO;
}

If we need only one column to be numeric

yyz$b <- as.numeric(as.character(yyz$b))

But, if all the columns needs to changed to numeric, use lapply to loop over the columns and convert to numeric by first converting it to character class as the columns were factor.

yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))

Both the columns in the OP's post are factor because of the string "n/a". This could be easily avoided while reading the file using na.strings = "n/a" in the read.table/read.csv or if we are using data.frame, we can have character columns with stringsAsFactors=FALSE (the default is stringsAsFactors=TRUE)

Regarding the usage of apply, it converts the dataset to matrix and matrix can hold only a single class. To check the class, we need

lapply(yyz, class)

Or

sapply(yyz, class)

Or check

str(yyz)

Just say if s or if not s. As in

s = ''
if not s:
    print 'not', s

So in your specific example, if I understand it correctly...

>>> import random
>>> l = ['', 'foo', '', 'bar']
>>> def default_str(l):
...     s = random.choice(l)
...     if not s:
...         print 'default'
...     else:
...         print s
... 
>>> default_str(l)
default
>>> default_str(l)
default
>>> default_str(l)
bar
>>> default_str(l)
default

In my case xxxx.pubxml.user was not loaded when tried to publish the application. I deleted the file and restart the Visual studio then created a new profile to publish it, problem is solved and published successfully.

Live DEMO

Check click area is not in the targeted element or in it's child

$(document).click(function (e) {
    if ($(e.target).parents(".dropdown").length === 0) {
        $(".dropdown").hide();
    }
});

UPDATE:

jQuery stop propagation is the best solution

Live DEMO

$(".button").click(function(e){
    $(".dropdown").show();
     e.stopPropagation();
});

$(".dropdown").click(function(e){
    e.stopPropagation();
});

$(document).click(function(){

OK! I know that jQuery is loading. I know that jQuery.textshadow.js is loading. I can find both of the scripts in Developer Tools.

The weird part: this code is working in the content area but not in the banner. Even with a dedicated fixIE.css. AND it works when I put the css inline. (That, of course, messes up FireFox.)

I have even put in a conditional IE span around the text field in the banner with no luck.

I found no difference and had the same errors in both jquery-1.4.2.min.js and jquery-1.2.6.min.js. jquery.textshadow.js was downloaded from the jQuery site while trying to find a solution to this problem.

Close Visual Studio and delete the bin and obj folders in your web project (or all projects in the solution).

Here are commands to delete these folders from all of your projects:

rm *\bin -r
rm *\obj -r

I think the "messy" second method, which is linked from another question here may be the only pure CSS solution.

If you're thinking about using JavaScript, then this was my solution to the problem:

demo: using a canvas element to fade text against an animated background

The idea is that your element with the text and the canvas element are one on top of the other. You keep the text in your element (in order to allow text selection, which isn't possible with canvas text), but make it completely transparent (with rgba(0,0,0,0), in order to have the text visible in IE8 and older - that's because you have no RGBa support and no canvas support in IE8 and older).

You then read the text inside your element and write it on the canvas with the same font properties so that each letter you write on the canvas is over the corresponding letter in the element with the text.

The canvas element does not support multi-line text, so you'll have to break the text into words and then keep adding words on a test line which you then measure. If the width taken by the test line is bigger than the maximum allowed width you can have for a line (you get that maximum allowed width by reading the computed width of the element with the text), then you write it on the canvas without the last word added, you reset the test line to be that last word, and you increase the y coordinate at which to write the next line by one line height (which you also get from the computed styles of your element with the text). With each line that you write, you also decrease the opacity of the text with an appropriate step (this step being inversely proportional to the average number of characters per line).

What you cannot do easily in this case is to justify text. It can be done, but it gets a bit more complicated, meaning that you would have to compute how wide should each step be and write the text word by word rather than line by line.

Also, keep in mind that if your text container changes width as you resize the window, then you'll have to clear the canvas and redraw the text on it on each resize.

OK, the code:

HTML:

<article>
  <h1>Interacting Spiral Galaxies NGC 2207/ IC 2163</h1>
  <em class='timestamp'>February 4, 2004 09:00 AM</em>
  <section class='article-content' id='art-cntnt'>
    <canvas id='c' class='c'></canvas>In the direction of <!--and so on-->  
  </section>
</article>

CSS:

html {
  background: url(moving.jpg) 0 0;
  background-size: 200%;
  font: 100%/1.3 Verdana, sans-serif;
  animation: ani 4s infinite linear;
}
article {
  width: 50em; /* tweak this ;) */
  padding: .5em;
  margin: 0 auto;
}
.article-content {
  position: relative;
  color: rgba(0,0,0,0);
  /* add slash at the end to check they superimpose *
  color: rgba(255,0,0,.5);/**/
}
.c {
  position: absolute;
  z-index: -1;
  top: 0; left: 0;
}
@keyframes ani { to { background-position: 100% 0; } }

JavaScript:

var wrapText = function(ctxt, s, x, y, maxWidth, lineHeight) {
  var words = s.split(' '), line = '', 
      testLine, metrics, testWidth, alpha = 1, 
      step = .8*maxWidth/ctxt.measureText(s).width;

  for(var n = 0; n < words.length; n++) {
    testLine = line + words[n] + ' ';
    metrics = ctxt.measureText(testLine);
    testWidth = metrics.width;
    if(testWidth > maxWidth) {
      ctxt.fillStyle = 'rgba(0,0,0,'+alpha+')';
      alpha  -= step;
      ctxt.fillText(line, x, y);
      line = words[n] + ' ';
      y += lineHeight;
    }
    else line = testLine;
  }
  ctxt.fillStyle = 'rgba(0,0,0,'+alpha+')';
  alpha  -= step;
  ctxt.fillText(line, x, y);
  return y + lineHeight;
}

window.onload = function() {
  var c = document.getElementById('c'), 
      ac = document.getElementById('art-cntnt'), 
      /* use currentStyle for IE9 */
      styles = window.getComputedStyle(ac),
      ctxt = c.getContext('2d'), 
      w = parseInt(styles.width.split('px')[0], 10),
      h = parseInt(styles.height.split('px')[0], 10),
      maxWidth = w, 
      lineHeight = parseInt(styles.lineHeight.split('px')[0], 10), 
      x = 0, 
      y = parseInt(styles.fontSize.split('px')[0], 10), 
      text = ac.innerHTML.split('</canvas>')[1];

  c.width = w;
  c.height = h;
  ctxt.font = '1em Verdana, sans-serif';
  wrapText(ctxt, text, x, y, maxWidth, lineHeight);
};

I have also been through this problem,

First i tried setting my password of root to blank using command :

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

But don't be happy , PHPMYADMIN uses 127.0.0.1 not localhost , i know you would say both are same but that is not the case , use the command mentioned underneath and you are done.

SET PASSWORD FOR [email protected]=PASSWORD('');

Just replace localhost with 127.0.0.1 and you are done .

Sql server unlike oracle does not need commits unless you are using transactions.
Immediatly after your update statement the table will be commited, don't use the commit command in this scenario.

I want to add that you can use the .WRITE clause for partial or full updates and high performance appends to varchar(max)/nvarchar(max) data types.

Here you can found full example of using .WRITE clause.
