bundle install --path vendor/cache

generally fixes it as that is the more common problem. Basically, your bundler path configuration is messed up. See their documentation (first paragraph) for where to find those configurations and change them manually if needed.

mkmf is part of the ruby1.9.1-dev package. This package contains the header files needed for extension libraries for Ruby 1.9.1. You need to install the ruby1.9.1-dev package by doing:

sudo apt-get install ruby1.9.1-dev

Then you can install Rails as per normal.

Generally it's easier to just do:

sudo apt-get install ruby-dev

i had a similiar problem and the gem string-scrub automagically fixed it for me. https://github.com/hsbt/string-scrub If the given string contains an invalid byte sequence then that invalid byte sequence is replaced with the unicode replacement character (?) and a new string is returned.

you have to open the file in append mode, which can be achieved by using the FileWriter(String fileName, boolean append) constructor.

output = new BufferedWriter(new FileWriter(my_file_name, true));

should do the trick

in every version of bootstrap,you can do it manually

1. set rtl direction to your body
2. in bootstrap.css file, look for ".col-sm-9{float:left}" expression,change it to float:right

this do most things that you want for rtl

        var flag=0;
        function username()
        {

- Another Update -

Since Twitter Bootstrap version 2.0 - which saw the removal of the .container-fluid class - it has not been possible to implement a two column fixed-fluid layout using just the bootstrap classes - however I have updated my answer to include some small CSS changes that can be made in your own CSS code that will make this possible

It is possible to implement a fixed-fluid structure using the CSS found below and slightly modified HTML code taken from the Twitter Bootstrap Scaffolding : layouts documentation page:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="fixed">  <!-- we want this div to be fixed width -->
            ...
        </div>
        <div class="hero-unit filler">  <!-- we have removed spanX class -->
            ...
        </div>
    </div>
</div>

CSS

/* CSS for fixed-fluid layout */

.fixed {
    width: 150px;  /* the fixed width required */
    float: left;
}

.fixed + div {
     margin-left: 150px;  /* must match the fixed width in the .fixed class */
     overflow: hidden;
}


/* CSS to ensure sidebar and content are same height (optional) */

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
    position: relative;
}

.filler:after{
    background-color:inherit;
    bottom: 0;
    content: "";
    height: auto;
    min-height: 100%;
    left: 0;
    margin:inherit;
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

I have kept the answer below - even though the edit to support 2.0 made it a fluid-fluid solution - as it explains the concepts behind making the sidebar and content the same height (a significant part of the askers question as identified in the comments)

Important

Answer below is fluid-fluid

Update As pointed out by @JasonCapriotti in the comments, the original answer to this question (created for v1.0) did not work in Bootstrap 2.0. For this reason, I have updated the answer to support Bootstrap 2.0

To ensure that the main content fills at least 100% of the screen height, we need to set the height of the html and body to 100% and create a new css class called .fill which has a minimum-height of 100%:

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
}

We can then add the .fill class to any element that we need to take up 100% of the sceen height. In this case we add it to the first div:

<div class="container-fluid fill">
    ...
</div>

To ensure that the Sidebar and the Content columns have the same height is very difficult and unnecessary. Instead we can use the ::after pseudo selector to add a filler element that will give the illusion that the two columns have the same height:

.filler::after {
    background-color: inherit;
    bottom: 0;
    content: "";
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

To make sure that the .filler element is positioned relatively to the .fill element we need to add position: relative to .fill:

.fill { 
    min-height: 100%;
    position: relative;
}

And finally add the .filler style to the HTML:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="span3">
            ...
        </div>
        <div class="span9 hero-unit filler">
            ...
        </div>
    </div>
</div>

Notes

• If you need the element on the left of the page to be the filler then you need to change right: 0 to left: 0.

SDP - a scalable size unit - basically it is not a unit, but dimension resources for different screen size.

Try the sdp library from Intuit. It's very handy to solve unit problems, and you can quickly support multiple screens.

Usage

android:paddingBottom="@dimen/_15sdp" for positive and android:layout_marginTop="@dimen/_minus10sdp" for negative sdp sdp

It has equivalent value in dp for each size in values-sw<N>dp folders (sw = smallestWidth).

Attention

Use it carefully! In most cases you still need to design a different layout for tablets.

Example

<LinearLayout
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_marginTop="@dimen/_minus10sdp"
          android:paddingBottom="@dimen/_15sdp"
          android:orientation="horizontal" >

                <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:includeFontPadding="false"
                    android:text="?"
                    android:textColor="#ED6C27"
                    android:textSize="@dimen/_70sdp"
                    android:textStyle="bold" />

                <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:includeFontPadding="false"
                    android:text="U"
                    android:textColor="@android:color/black"
                    android:textSize="@dimen/_70sdp" />
            </LinearLayout>

You can use db for text size, but I prefer ssp for text size.

To delete rows empty in table

syntax:

DELETE FROM table_name 
WHERE column_name IS NULL;

example:

Table name: data ---> column name: pkdno

DELETE FROM data 
WHERE pkdno IS NULL;

Answer: 5 rows deleted. (sayso)

I use char 'f', 'm' and 'u' because I surmise the gender from name, voice and conversation, and sometimes don't know the gender. The final determination is their opinion.

It really depends how well you know the person and whether your criteria is physical form or personal identity. A psychologist might need additional options - cross to female, cross to male, trans to female, trans to male, hermaphrodite and undecided. With 9 options, not clearly defined by a single character, I might go with Hugo's advice of tiny integer.

I'd use the accepted answer, but another possibility is to use a table variable to hold a numbered set of values (in this case just the ID field of a table) and loop through those by Row Number with a JOIN to the table to retrieve whatever you need for the action within the loop.

DECLARE @RowCnt int; SET @RowCnt = 0 -- Loop Counter

-- Use a table variable to hold numbered rows containg MyTable's ID values
DECLARE @tblLoop TABLE (RowNum int IDENTITY (1, 1) Primary key NOT NULL,
     ID INT )
INSERT INTO @tblLoop (ID)  SELECT ID FROM MyTable

  -- Vars to use within the loop
  DECLARE @Code NVarChar(10); DECLARE @Name NVarChar(100);

WHILE @RowCnt < (SELECT COUNT(RowNum) FROM @tblLoop)
BEGIN
    SET @RowCnt = @RowCnt + 1
    -- Do what you want here with the data stored in tblLoop for the given RowNum
    SELECT @Code=Code, @Name=LongName
      FROM MyTable INNER JOIN @tblLoop tL on MyTable.ID=tL.ID
      WHERE tl.RowNum=@RowCnt
    PRINT Convert(NVarChar(10),@RowCnt) +' '+ @Code +' '+ @Name
END

Simple try to remove name attribute from input element.
So it has to look like

<input type="checkbox" checked="" id="class_box_2" value="2">

Here's how I did it in Excel 2003 using conditional formatting.

To apply conditional formatting to Sheet1 using values from Sheet2, you need to mirror the values into Sheet1.

Creating a mirror of Sheet2, column B in Sheet 1

1. Go to Sheet1.
2. Insert a new column by right-clicking column A's header and selecting "Insert".

3. Enter the following formula into A1:

   =IF(ISBLANK(Sheet2!B1),"",Sheet2!B1)

4. Copy A1 by right-clicking it and selecting "Copy".
5. Paste the formula into column A by right-clicking its header and selecting "Paste".

Sheet1, column A should now exactly mirror the values in Sheet2, column B.

(Note: if you don't like it in column A, it works just as well to have it in column Z or anywhere else.)

Applying the conditional formatting

1. Stay on Sheet1.
2. Select column B by left-clicking its header.
3. Select the menu item Format > Conditional Formatting...

4. Change Condition 1 to "Formula is" and enter this formula:

   =MATCH(B1,$A:$A,0)

5. Click the Format... button and select a green background.

You should now see the green background applied to the matching cells in Sheet1.

Hiding the mirror column

1. Stay on Sheet1.
2. Right-click the header on column A and select "Hide".

This should automatically update Sheet1 whenever anything in Sheet2 is changed.

I asked in #machomebrew and learned that you can switch between versions using brew switch.

$ brew switch libfoo mycopy 

to get version mycopy of libfoo.

This is a good example where you want to get count of Pincode which stored in the last of address field

SELECT DISTINCT

    count(*) AS count
FROM
    datafile
WHERE
    address IS NOT NULL
GROUP BY
    RIGHT (address, 6)

Adding a directory to subversion, and ignoring the directory contents

svn propset svn:ignore '\*.*' .

or

svn propset svn:ignore '*' .

There's no need to use a library for such a trivial task:

var divs = document.getElementsByTagName("div");   // order: first, second, third
divs[2].parentNode.insertBefore(divs[2], divs[0]); // order: third, first, second
divs[2].parentNode.insertBefore(divs[2], divs[1]); // order: third, second, first

This takes account of the fact that getElementsByTagName returns a live NodeList that is automatically updated to reflect the order of the elements in the DOM as they are manipulated.

You could also use:

var divs = document.getElementsByTagName("div");   // order: first, second, third
divs[0].parentNode.appendChild(divs[0]);           // order: second, third, first
divs[1].parentNode.insertBefore(divs[0], divs[1]); // order: third, second, first

and there are various other possible permutations, if you feel like experimenting:

divs[0].parentNode.appendChild(divs[0].parentNode.replaceChild(divs[2], divs[0]));

for example :-)

The bounds of an UIView is the rectangle, expressed as a location (x,y) and size (width,height) relative to its own coordinate system (0,0).

The frame of an UIView is the rectangle, expressed as a location (x,y) and size (width,height) relative to the superview it is contained within.

So, imagine a view that has a size of 100x100 (width x height) positioned at 25,25 (x,y) of its superview. The following code prints out this view's bounds and frame:

// This method is in the view controller of the superview
- (void)viewDidLoad {
    [super viewDidLoad];

    NSLog(@"bounds.origin.x: %f", label.bounds.origin.x);
    NSLog(@"bounds.origin.y: %f", label.bounds.origin.y);
    NSLog(@"bounds.size.width: %f", label.bounds.size.width);
    NSLog(@"bounds.size.height: %f", label.bounds.size.height);

    NSLog(@"frame.origin.x: %f", label.frame.origin.x);
    NSLog(@"frame.origin.y: %f", label.frame.origin.y);
    NSLog(@"frame.size.width: %f", label.frame.size.width);
    NSLog(@"frame.size.height: %f", label.frame.size.height);
}

And the output of this code is:

bounds.origin.x: 0
bounds.origin.y: 0
bounds.size.width: 100
bounds.size.height: 100

frame.origin.x: 25
frame.origin.y: 25
frame.size.width: 100
frame.size.height: 100

So, we can see that in both cases, the width and the height of the view is the same regardless of whether we are looking at the bounds or frame. What is different is the x,y positioning of the view. In the case of the bounds, the x and y coordinates are at 0,0 as these coordinates are relative to the view itself. However, the frame x and y coordinates are relative to the position of the view within the parent view (which earlier we said was at 25,25).

There is also a great presentation that covers UIViews. See slides 1-20 which not only explain the difference between frames and bounds but also show visual examples.

UTF-8 does not have a BOM as it is both superfluous and invalid. Where a BOM is helpful is in UTF-16 which may be byte swapped as in the case of Microsoft. UTF-16 if for internal representation in a memory buffer. Use UTF-8 for interchange. By default both UTF-8, anything else derived from US-ASCII and UTF-16 are natural/network byte order. The Microsoft UTF-16 requires a BOM as it is byte swapped.

To covert Windows-1252 to ISO8859-15, I first convert ISO8859-1 to US-ASCII for codes with similar glyphs. I then convert Windows-1252 up to ISO8859-15, other non-ISO8859-15 glyphs to multiple US-ASCII characters.

New, Edited Answer:

Add this in viewDidLayoutSubviews

SWIFT

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    let indexPath = IndexPath(item: 12, section: 0)
    self.collectionView.scrollToItem(at: indexPath, at: [.centeredVertically, .centeredHorizontally], animated: true)
}

Normally, .centerVertically is the case

ObjC

-(void)viewDidLayoutSubviews {
   [super viewDidLayoutSubviews];
    NSIndexPath *indexPath = [NSIndexPath indexPathForItem:12 inSection:0];
   [self.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:UICollectionViewScrollPositionCenteredVertically | UICollectionViewScrollPositionCenteredHorizontally animated:NO];
}

Old answer working for older iOS

Add this in viewWillAppear:

[self.view layoutIfNeeded];
[self.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:UICollectionViewScrollPositionCenteredVertically animated:NO];

Even if you want to accept numbers for the input, I would recommend using the text type.

<input type="text" name"some-number" />

Client-side run some jQuery validations to verify it's a number.

Then in your server side code, run some validation to verify it is in fact a numerical value.

I am using Retrofit 1.9 to obtain a XML.

public class ServicioConexionRetrofitXML {

    public static final String API_BASE_URL = new GestorPreferencias().getPreferencias().getHost();
    public static final long tiempoMaximoRespuestaSegundos = 60;
    public static final long tiempoMaximoLecturaSegundos = 100;
    public static final OkHttpClient clienteOkHttp = new OkHttpClient();


    private static RestAdapter.Builder builder = new RestAdapter.Builder().
            setEndpoint(API_BASE_URL).
            setClient(new OkClient(clienteOkHttp)).setConverter(new SimpleXMLConverter());


    public static <S> S createService(Class<S> serviceClass) {
        clienteOkHttp.setConnectTimeout(tiempoMaximoRespuestaSegundos, TimeUnit.SECONDS);
        clienteOkHttp.setReadTimeout(tiempoMaximoLecturaSegundos, TimeUnit.SECONDS);
        RestAdapter adapter = builder.build();
        return adapter.create(serviceClass);
    }

}

If you are using Retrofit 1.9.0 and okhttp 2.6.0, add to your Gradle file.

    compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile 'com.squareup.okhttp:okhttp:2.6.0'
    // Librería de retrofit para XML converter (Simple) Se excluyen grupos para que no entre
    // en conflicto.
    compile('com.squareup.retrofit:converter-simplexml:1.9.0') {
        exclude group: 'xpp3', module: 'xpp3'
        exclude group: 'stax', module: 'stax-api'
        exclude group: 'stax', module: 'stax'
    }

Note: If you need to fetch a JSON, just remove from code above.

.setConverter(new SimpleXMLConverter())

If you are currently writing the application, than the answer is to use System.currentTimeMillis or System.nanoTime serve the purpose as pointed by people above.

But if you have already written the code, and you don't want to change it its better to use Spring's method interceptors. So for instance your service is :

public class MyService { 
    public void doSomething() {
        for (int i = 1; i < 10000; i++) {
            System.out.println("i=" + i);
        }
    }
}

To avoid changing the service, you can write your own method interceptor:

public class ServiceMethodInterceptor implements MethodInterceptor {
    public Object invoke(MethodInvocation methodInvocation) throws Throwable {
        long startTime = System.currentTimeMillis();
        Object result = methodInvocation.proceed();
        long duration = System.currentTimeMillis() - startTime;
        Method method = methodInvocation.getMethod();
        String methodName = method.getDeclaringClass().getName() + "." + method.getName();
        System.out.println("Method '" + methodName + "' took " + duration + " milliseconds to run");
        return null;
    }
}

Also there are open source APIs available for Java, e.g. BTrace. or Netbeans profiler as suggested above by @bakkal and @Saikikos. Thanks.

Database in the connection string didn't exist. I thought it did but it hadn't been created yet.

Use .push:

This was the only thing that fixed it.

It happens when your HTTP request's headers claim that the content is gzip encoded, but it isn't. Turn off gzip encoding setting or make sure the content is in fact encoded.

I found SimulatorManager application very useful. It takes you directly to the application folder of installed simulators. I have tried with 7.1, 8.0 and 8.1 simulators.

SimulatorManager resides as an icon in the system tray and provides an option to "Launch At Login".

Note: This works only with Xcode 6 (6.1.1 in my case) and above.

Hope that helps!

insert into received_messages(id, content, status)

Since you don't really need the total number, and in fact want to perform an action after a certain number (in your case 5000), you can use java.nio.file.Files.newDirectoryStream. The benefit is that you can exit early instead having to go through the entire directory just to get a count.

public boolean isOverMax(){
    Path dir = Paths.get("C:/foo/bar");
    int i = 1;

    try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir)) {
        for (Path p : stream) {
            //larger than max files, exit
            if (++i > MAX_FILES) {
                return true;
            }
        }
    } catch (IOException ex) {
        ex.printStackTrace();
    }

    return false;
}

The interface doc for DirectoryStream also has some good examples.

Give -f to pkill

pkill -f /usr/local/bin/fritzcap.py

exact path of .py file is

What you could do is copy the code from tkinter.py into a file called mytkinter.py, then do this code:

import tkinter, mytkinter
root = tkinter.Tk()
window = mytkinter.Tk()
button = mytkinter.Button(window, text="Search", width = 7,
                               command=cmd)
button2 = tkinter.Button(root, text="Search", width = 7,
                               command=cmdtwo)

And you have two windows which don't collide!

Or simple try:

> sudo easy_install MySQL-python

If it gives a error like below:

EnvironmentError: mysql_config not found

, then just run this

> export PATH=$PATH:/usr/local/mysql/bin

You will use the following query:

SELECT * FROM [table] GROUP BY NUMBER;

Where [table] is the name of the table.

This provides a unique listing for the NUMBER column however the other columns may be meaningless depending on the vendor implementation; which is to say they may not together correspond to a specific row or rows.

In addition to the anwser of Bill the Lizard:

Most of the backends parse the raw post data. In PHP for example, you will have an array $_POST in which individual variables within the post data will be stored. In this case you have to use an additional header "Content-type: application/x-www-form-urlencoded":

Set objHTTP = CreateObject("WinHttp.WinHttpRequest.5.1")
URL = "http://www.somedomain.com"
objHTTP.Open "POST", URL, False
objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
objHTTP.send ("var1=value1&var2=value2&var3=value3")

Otherwise you have to read the raw post data on the variable "$HTTP_RAW_POST_DATA".

Simply follow three steps;

1. Clear npm cache forcefully:

   npm cache clean -f

2. Install n package globally using npm:

   npm install -g n

3. Install from any of three options:

   a. sudo n stable (get the stable version)

   b. sudo n latest (get the latest version of node)

   c. sudo n x.x.x (get the specific version of node)

Another option you can check the document.readyState like,

var chkReadyState = setInterval(function() {
    if (document.readyState == "complete") {
        // clear the interval
        clearInterval(chkReadyState);
        // finally your page is loaded.
    }
}, 100);

From the documentation of readyState Page the summary of complete state is

Returns "loading" while the document is loading, "interactive" once it is finished parsing but still loading sub-resources, and "complete" once it has loaded.

The triple quotes answer is great for ASCII art, but for those wondering - what if my multiple lines are a tuple, list, or other iterable that returns strings (perhaps a list comprehension?), then how about:

print("\n".join(<*iterable*>))

For example:

print("\n".join(["{}={}".format(k, v) for k, v in os.environ.items() if 'PATH' in k]))

I know it's been a while on this question, but I was just looking for the same answer and found this seems to be the simplest solution:

select * from sales where datediff(dd, salesDate, '20101111') = 0

I actually use it more to find things within the last day or two, so my version looks like this:

select * from sales where datediff(dd, salesDate, getdate()) = 0

And by changing the 0 for today to a 1 I get yesterday's transactions, 2 is the day before that, and so on. And if you want everything for the last week, just change the equals to a less-than-or-equal-to:

select * from sales where datediff(dd, salesDate, getdate()) <= 7

In makefile language $@ means "name of the target", so rm -f $@ translates to rm -f clean.

You need to specify to rm what exactly you want to delete, like rm -f *.o code1 code2

I assume that there exist some internal psql command for this, but you could also run the script command from util-linux-ng package:

DESCRIPTION Script makes a typescript of everything printed on your terminal.

In case you want to use sorted() function: sorted(list1, key=int)

It returns a new sorted list.

You can simply do:

var ms = new MemoryStream(File.ReadAllBytes(filePath));

Stream position is 0 and ready to use.

When we try to drop a column which is depended upon then we see this kind of error:

The object 'DF__*' is dependent on column ''.

drop the constraint which is dependent on that column with:

ALTER TABLE TableName DROP CONSTRAINT dependent_constraint;

Example:

Msg 5074, Level 16, State 1, Line 1

The object 'DF__Employees__Colf__1273C1CD' is dependent on column 'Colf'.

Msg 4922, Level 16, State 9, Line 1

ALTER TABLE DROP COLUMN Colf failed because one or more objects access this column.

Drop Constraint(DF__Employees__Colf__1273C1CD):

ALTER TABLE Employees DROP CONSTRAINT DF__Employees__Colf__1273C1CD;

Then you can Drop Column:

Alter Table TableName Drop column ColumnName

The official way to install Popper.js is trough npm, Yarn or NuGet.

Use either one of the following commands :

npm i popper.js
yarn add popper.js
PM> Install-Package popper.js

Everything is described in the library readme.

Regarding the "downloads the zip", the zip clearly states that it contains the source code of the library.

Edit:

Starting from version 1.12.0, Popper.js is available as Bower dependency.

This installation method is going to be supported only for the 1.x version of Popper.js and will be removed in 2.x.

You should migrate your dependencies management to a modern system like npm or Yarn, as Bower suggests as well.

django is smart enough. Actually we don't need to define oneToMany field. It will be automatically generated by django for you :-). We only need to define foreignKey in related table. In other words, we only need to define ManyToOne relation by using foreignKey.

class Car(models.Model):
    // wheels = models.oneToMany() to get wheels of this car [**it is not required to define**].


class Wheel(models.Model):
    car = models.ForeignKey(Car, on_delete=models.CASCADE)  

if we want to get the list of wheels of particular car. we will use python's auto generated object wheel_set. For car c you will use c.wheel_set.all()

the prototype way

<div id="sub1" title="some text on mouse over">some text</div>


<script type="text/javascript">//<![CDATA[
  $("sub1").observe("mouseover", function() {
    alert(this.readAttribute("title"));
  });
//]]></script>

include Prototype Lib for testing

<script type="text/javascript" 
  src="http://ajax.googleapis.com/ajax/libs/prototype/1.6.0.2/prototype.js"></script>

You could use the ready to use Url Rewrite Filter with a rule like this one:

<rule>
  <from>^/Check_License/Dir_My_App/Dir_ABC/My_Obj_([0-9]+)$</from>
  <to>/Check_License?Contact_Id=My_Obj_$1</to>
</rule>

If you also want to bind closing of infowindow to some event, try something like this

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
        windows.push(infowindow)
        google.maps.event.addListener(map,'click', function(){ 
            infowindow.close();
        }); 
    };
})(marker,content,infowindow)); 

Here is what I did and I'm happy to say that this worked for me. I too wanted a 2x2, 3x3 etc. grid of items to cover the entire screen. Gridlayouts do not adhere to the width of the screen. LinearLayouts kind of work but you cant use nested weights.

The best option for me was to use Fragments I used this tutorial to get started with what I wanted to do.

Here is some code:

Main Activity:

public class GridHolderActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main_6);
    }
}

activity_main_6 XML (inflates 3 fragments)

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <fragment
        android:id="@+id/frag1"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:name=".TwoHorizontalGridFragment"
        tools:layout="@layout/two_horiz" />
    <fragment
        android:id="@+id/frag2"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:name=".TwoHorizontalGridFragment"
        tools:layout="@layout/two_horiz" />
    <fragment
        android:id="@+id/frag3"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:name=".Grid.TwoHorizontalGridFragment"
        tools:layout="@layout/two_horiz" />

Base fragment layout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="wrap_content"
    android:layout_gravity="center"
    android:layout_height="match_parent">

    <ImageQueue
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:id="@+id/img1"
        android:layout_weight="1"/>


    <ImageQueue
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:id="@+id/img2"
        android:layout_weight="1"/>
</LinearLayout>

Fragment Class (only handles initialization of a custom view) inflates 2 tiles per fragment

public class TwoHorizontalGridFragment extends Fragment {
private View rootView;

private ImageQueue imageQueue1;
private ImageQueue imageQueue2;

@Override
public View onCreateView(LayoutInflater inflater,
                         ViewGroup container, Bundle savedInstanceState) {
    /**
     * Inflate the layout for this fragment
     */
    rootView = inflater.inflate(
            R.layout.two_horiz, container, false);
    return rootView;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    imageQueue1 = (ImageQueue)rootView.findViewById(R.id.img1);
    imageQueue2 = (ImageQueue)rootView.findViewById(R.id.img2);
    imageQueue1.updateFiles();
    imageQueue2.updateFiles();
}

}

Thats it!

This is a weird work around to using nested weights, essentially. It gives me a perfect 2x3 grid that fills the entire screen of both my 10 inch tablet and my HTC droid DNA. Let me know how it goes for you!

To return the last argument of the most recently used command use the special parameter:

$_

In this instance it will work if it is used within the script before another command has been invoked.

My best guess would be that you are on a shared server and the session files are mixed along all users so you can't, nor you should, delete them. What you can do, if you are worried about scaling and/or your users session privacy, is to move sessions to the database.

Start writing that Cookie to the database and you've got a long way towards scaling you app across multiple servers when time is due.

Apart from that I would not worry much with the 145.000 files.

This can be achieved by attaching a "tabindex" to an element. This will make that element "clickable". You can then use :focus to select your hidden div as follows...

.clicker {_x000D_
width:100px;_x000D_
height:100px;_x000D_
background-color:blue;_x000D_
outline:none;_x000D_
cursor:pointer;_x000D_
}_x000D_
_x000D_
.hiddendiv{_x000D_
display:none;_x000D_
height:200px;_x000D_
background-color:green;_x000D_
}_x000D_
_x000D_
.clicker:focus + .hiddendiv{_x000D_
display:block;_x000D_
}

<html>_x000D_
<head>_x000D_
</head>_x000D_
<body>_x000D_
_x000D_
<div>_x000D_
<div class="clicker" tabindex="1">Click me</div>_x000D_
<div class="hiddendiv"></div>_x000D_
</div>_x000D_
_x000D_
</body>_x000D_
_x000D_
</html>

The + selector will select the nearest element AFTER the "clicker" div. You can use other selectors but I believe there is no current way to select an element that is not a sibling or child.

I installed Node.js on bluehost.com (a shared server) using:

wget <path to download file>
tar -xf <gzip file>
mv <gzip_file_dir> node

This will download the tar file, extract to a directory and then rename that directory to the name 'node' to make it easier to use.

then

./node/bin/npm install jt-js-sample

Returns:
npm WARN engine [email protected]: wanted: {"node":"0.10.x"} (current: {"node":"0.12.4","npm":"2.10.1"})
[email protected] node_modules/jt-js-sample
+-- [email protected] ([email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected])

I can now use the commands:

# ~/node/bin/node -v
v0.12.4

# ~/node/bin/npm -v
2.10.1

For security reasons, I have renamed my node directory to something else.

Open: ./src/app/app.module.ts
And import Firebase Modules at the top:

import { environment } from '../environments/environment';
import { AngularFireModule } from 'angularfire2';
import { AngularFirestoreModule } from 'angularfire2/firestore';

And VERY IMPORTANT:
Remember to update 'imports' in NgModule:

@NgModule({
  declarations: [
    AppComponent,
    OtherComponent // Add other components here
    ...
  ],
  imports: [
    BrowserModule,
    AngularFireModule.initializeApp(environment.firebase, 'your-APP-name-here'),
    AngularFirestoreModule
  ],
  ...
})

Give it a try, it shall now work.
For detailed information follow the angularfire2 documentation:
https://github.com/angular/angularfire2/blob/master/docs/install-and-setup.md
Good luck!

Suppose you have service reference of the name localhost in your web.config so you can go as follows

localhost.Service objWebService = newlocalhost.Service();
localhost.AuthSoapHd objAuthSoapHeader = newlocalhost.AuthSoapHd();
string strUsrName =ConfigurationManager.AppSettings["UserName"];
string strPassword =ConfigurationManager.AppSettings["Password"];

objAuthSoapHeader.strUserName = strUsrName;
objAuthSoapHeader.strPassword = strPassword;

objWebService.AuthSoapHdValue =objAuthSoapHeader;
string str = objWebService.HelloWorld();

Response.Write(str);

As written in other answers, assert statements are used to check the state of the program at a given point.

I won't repeat what was said about associated message, parentheses, or -O option and __debug__ constant. Check also the doc for first hand information. I will focus on your question: what is the use of assert? More precisely, when (and when not) should one use assert?

The assert statements are useful to debug a program, but discouraged to check user input. I use the following rule of thumb: keep assertions to detect a this should not happen situation. A user input may be incorrect, e.g. a password too short, but this is not a this should not happen case. If the diameter of a circle is not twice as large as its radius, you are in a this should not happen case.

The most interesting, in my mind, use of assert is inspired by the programming by contract as described by B. Meyer in [Object-Oriented Software Construction]( https://www.eiffel.org/doc/eiffel/Object-Oriented_Software_Construction%2C_2nd_Edition ) and implemented in the [Eiffel programming language]( https://en.wikipedia.org/wiki/Eiffel_(programming_language)). You can't fully emulate programming by contract using the assert statement, but it's interesting to keep the intent.

Here's an example. Imagine you have to write a head function (like the [head function in Haskell]( http://www.zvon.org/other/haskell/Outputprelude/head_f.html)). The specification you are given is: "if the list is not empty, return the first item of a list". Look at the following implementations:

>>> def head1(xs): return xs[0]

And

>>> def head2(xs):
...     if len(xs) > 0:
...         return xs[0]
...     else:
...         return None

_{(Yes, this can be written as return xs[0] if xs else None, but that's not the point)}.

If the list is not empty, both functions have the same result and this result is correct:

>>> head1([1, 2, 3]) == head2([1, 2, 3]) == 1
True

Hence, both implementations are (I hope) correct. They differ when you try to take the head item of an empty list:

>>> head1([])
Traceback (most recent call last):
...
IndexError: list index out of range

But:

>>> head2([]) is None
True

Again, both implementations are correct, because no one should pass an empty list to these functions (we are out of the specification). That's an incorrect call, but if you do such a call, anything can happen. One function raises an exception, the other returns a special value. The most important is: we can't rely on this behavior. If xs is empty, this will work:

print(head2(xs))

But this will crash the program:

print(head1(xs))

To avoid some surprises, I would like to know when I'm passing some unexpected argument to a function. In other words: I would like to know when the observable behavior is not reliable, because it depends on the implementation, not on the specification. Of course, I can read the specification, but programmers do not always read carefully the docs.

Imagine if I had a way to insert the specification into the code to get the following effect: when I violate the specification, e.g by passing an empty list to head, I get a warning. That would be a great help to write a correct (i.e. compliant with the specification) program. And that's where assert enters on the scene:

>>> def head1(xs):
...     assert len(xs) > 0, "The list must not be empty"
...     return xs[0]

And

>>> def head2(xs):
...     assert len(xs) > 0, "The list must not be empty"
...     if len(xs) > 0:
...         return xs[0]
...     else:
...         return None

Now, we have:

>>> head1([])
Traceback (most recent call last):
...
AssertionError: The list must not be empty

And:

>>> head2([])
Traceback (most recent call last):
...
AssertionError: The list must not be empty

Note that head1 throws an AssertionError, not an IndexError. That's important because an AssertionError is not any runtime error: it signals a violation of the specification. I wanted a warning, but I get an error. Fortunately, I can disable the check (using the -O option), but at my own risks. I will do it a crash is really expensive, and hope for the best. Imagine my program is embedded in a spaceship that travels through a black hole. I will disable assertions and hope the program is robust enough to not crash as long as possible.

This example was only about preconditions, be you can use assert to check postconditions (the return value and/or the state) and invariants (state of a class). Note that checking postconditions and invariants with assert can be cumbersome:

• for postconditions, you need to assign the return value to a variable, and maybe to store the iniial state of the object if you are dealing with a method;
• for invariants, you have to check the state before and after a method call.

You won't have something as sophisticated as Eiffel, but you can however improve the overall quality of a program.

To summarize, the assert statement is a convenient way to detect a this should not happen situation. Violations of the specification (e.g. passing an empty list to head) are first class this should not happen situations. Hence, while the assert statement may be used to detect any unexpected situation, it is a privilegied way to ensure that the specification is fulfilled. Once you have inserted assert statements into the code to represent the specification, we can hope you have improved the quality of the program because incorrect arguments, incorrect return values, incorrect states of a class..., will be reported.

That's not the way to concat in MYSQL. Use the CONCAT function Have a look here: http://dev.mysql.com/doc/refman/4.1/en/string-functions.html#function_concat

Redirect sys.stdout to an open file handle and then all printed output goes to a file:

import sys
filename  = open("outputfile",'w')
sys.stdout = filename
print "Anything printed will go to the output file"

Here you can try something like this

EDIT: REVISED EXAMPLE (added one new solution) http://jsfiddle.net/jszjz/10/

Code explanation

var jqThis = $('#adjinput'), //object of the input field in jQuery
    fontSize = parseInt( jqThis.css('font-size') ) / 2, //its font-size
    //its min Width (the box won't become smaller than this
    minWidth= parseInt( jqThis.css('min-width') ), 
    //its maxWidth (the box won't become bigger than this)
    maxWidth= parseInt( jqThis.css('max-width') );

jqThis.bind('keydown', function(e){ //on key down
   var newVal = (this.value.length * fontSize); //compute the new width

   if( newVal  > minWidth && newVal <= maxWidth ) //check to see if it is within Min and Max
       this.style.width = newVal + 'px'; //update the value.
});

and the css is pretty straightforward too

#adjinput{
    max-width:200px !important;
    width:40px;
    min-width:40px;
    font-size:11px;
}

EDIT: Another solution is to havethe user type what he wants and on blur (focus out), grab the string (in the same font size) place it in a div - count the div's width - and then with a nice animate with a cool easing effect update the input fields width. The only drawback is that the input field will remain "small" while the user types. Or you can add a timeout : ) you can check such a kind of solution on the fiddle above too!

you can use g++ --std=c++0x example.cpp -o example

You can do as follows with pure JS. You just need to provide the function with the number of seconds and it will do the rest.

var insertZero = n => n < 10 ? "0"+n : ""+n,_x000D_
   displayTime = n => n ? time.textContent = insertZero(~~(n/3600)%3600) + ":" +_x000D_
                                             insertZero(~~(n/60)%60) + ":" +_x000D_
                                             insertZero(n%60)_x000D_
                        : time.textContent = "IGNITION..!",_x000D_
 countDownFrom = n => (displayTime(n), setTimeout(_ => n ? sid = countDownFrom(--n)_x000D_
                                                         : displayTime(n), 1000)),_x000D_
           sid;_x000D_
countDownFrom(3610);_x000D_
setTimeout(_ => clearTimeout(sid),20005);

<div id="time"></div>

Also you can use default() filter. Or just a shortcut d()

According to http://youmightnotneedjquery.com/#ready a nice replacement that still works with IE8 is

function ready(fn) {_x000D_
  if (document.readyState != 'loading') {_x000D_
    fn();_x000D_
  } else if (document.addEventListener) {_x000D_
    document.addEventListener('DOMContentLoaded', fn);_x000D_
  } else {_x000D_
    document.attachEvent('onreadystatechange', function() {_x000D_
      if (document.readyState != 'loading')_x000D_
        fn();_x000D_
    });_x000D_
  }_x000D_
}_x000D_
_x000D_
// test_x000D_
window.ready(function() {_x000D_
    alert('it works');_x000D_
});

improvements: Personally I would also check if the type of fn is a function. And as @elliottregan suggested remove the event listener after use.

The reason I answer this question late is because I was searching for this answer but could not find it here. And I think this is the best solution.

Try this solution:

There is a data item in your table whose associated value doesn't exist in the table you want to use it as a primary key table. Make your table empty or add the associated value to the second table.

#!/usr/bin/python

with open(FileName) as f:
    newText=f.read().replace('A', 'Orange')

with open(FileName, "w") as f:
    f.write(newText)

font-size:35px;

So like this:

<html>
  <tr>
  <td style="padding-left:5px;padding-bottom:3px;"> 
    <strong style="font-size:35px;">Datum:</strong>
    <br/>
    November 2010 
  </td>
  </tr>
</html>

Although inline styles are a bad practice and you should class things. Also you should use a <strong></strong> tag instead of <b></b>

If you really have:

var s = ['{"Select":"11", "PhotoCount":"12"}','{"Select":"21", "PhotoCount":"22"}'];

then simply:

var objs = $.map(s, $.parseJSON);

Here's a demo.

Here is an Enum factory that avoids realm issues by using a namespace and Symbol.for:

const Enum = (n, ...v) => Object.freeze(v.reduce((o, v) => (o[v] = Symbol.for(`${n}.${v}`), o), {}));

const COLOR = Enum("ACME.Color", "Blue", "Red");
console.log(COLOR.Red.toString());
console.log(COLOR.Red === Symbol.for("ACME.Color.Red"));

If you own the HTML code then it might be wise to assign an id to this href. Then your code would look like this:

<a id="sign_up" class="sign_new">Sign up</a>

And jQuery:

$(document).ready(function(){
    $('#sign_up').click(function(){
        alert('Sign new href executed.');
    });
});

If you do not own the HTML then you'd need to change $('#sign_up') to $('a.sign_new'). You might also fire event.stopPropagation() if you have a href in anchor and do not want it handled (AFAIR return false might work as well).

$(document).ready(function(){
    $('#sign_up').click(function(event){
        alert('Sign new href executed.');
        event.stopPropagation();
    });
});

I've been using Typescript in my current angular project for about a year and a half and while there are a few issues with definitions every now and then the DefinitelyTyped project does an amazing job at keeping up with the latest versions of most popular libraries.

Having said that there is a definite learning curve when transitioning from vanilla JavaScript to TS and you should take into account the ability of you and your team to make that transition. Also if you are going to be using angular 1.x most of the examples you will find online will require you to translate them from JS to TS and overall there are not a lot of resources on using TS and angular 1.x together right now.

If you plan on using angular 2 there are a lot of examples using TS and I think the team will continue to provide most of the documentation in TS, but you certainly don't have to use TS to use angular 2.

ES6 does have some nice features and I personally plan on getting more familiar with it but I would not consider it a production-ready language at this point. Mainly due to a lack of support by current browsers. Of course, you can write your code in ES6 and use a transpiler to get it to ES5, which seems to be the popular thing to do right now.

Overall I think the answer would come down to what you and your team are comfortable learning. I personally think both TS and ES6 will have good support and long futures, I prefer TS though because you tend to get language features quicker and right now the tooling support (in my opinion) is a little better.

Remove basically works on the value . Delete and pop work on the index

Remove basically removes the first matching value. Delete deletes the item from a specific index Pop basically takes an index and returns the value at that index. Next time you print the list the value doesnt appear.

In node.js we can use node-geocoder npm module to get address from lat, lng.,

geo.js

var NodeGeocoder = require('node-geocoder');

var options = {
  provider: 'google',
  httpAdapter: 'https', // Default
  apiKey: ' ', // for Mapquest, OpenCage, Google Premier
  formatter: 'json' // 'gpx', 'string', ...
};

var geocoder = NodeGeocoder(options);

geocoder.reverse({lat:28.5967439, lon:77.3285038}, function(err, res) {
  console.log(res);
});

output:

node geo.js

I was trying to make my Angular app scroll to an anchor opon loading and ran into the URL rewriting rules of $routeProvider.

After long experimentation I settled on this:

1. register a document.onload event handler from the .run() section of the Angular app module.
2. in the handler find out what the original has anchor tag was supposed to be by doing some string operations.
3. override location.hash with the stripped down anchor tag (which causes $routeProvider to immediately overwrite it again with it's "#/" rule. But that is fine, because Angular is now in sync with what is going on in the URL 4) call $anchorScroll().

angular.module("bla",[]).}])_x000D_
.run(function($location, $anchorScroll){_x000D_
         $(document).ready(function() {_x000D_
  if(location.hash && location.hash.length>=1)      {_x000D_
   var path = location.hash;_x000D_
   var potentialAnchor = path.substring(path.lastIndexOf("/")+1);_x000D_
   if ($("#" + potentialAnchor).length > 0) {   // make sure this hashtag exists in the doc.                          _x000D_
       location.hash = potentialAnchor;_x000D_
       $anchorScroll();_x000D_
   }_x000D_
  }  _x000D_
 });

The newly popular tidyr package does this with separate. It uses regular expressions so you'll have to escape the |

df <- data.frame(ID=11:13, FOO=c('a|b', 'b|c', 'x|y'))
separate(data = df, col = FOO, into = c("left", "right"), sep = "\\|")

  ID left right
1 11    a     b
2 12    b     c
3 13    x     y

though in this case the defaults are smart enough to work (it looks for non-alphanumeric characters to split on).

separate(data = df, col = FOO, into = c("left", "right"))

I found the answer:

$mail->AddEmbeddedImage('img/2u_cs_mini.jpg', 'logo_2u');

and on the <img> tag put src='cid:logo_2u'

Open the Terminal -> copy below command

sudo gem install cocoapods

It will install the latest stable version of cocoapods.

after that, you need to update pod using below command

pod setup

You can check pod version using below command

pod --version

The latest version of .Net (v4.6) just added built-in support for Unix time conversions. That includes both to and from Unix time represented by either seconds or milliseconds.

• Unix time in seconds to DateTimeOffset:

DateTimeOffset dateTimeOffset = DateTimeOffset.FromUnixTimeSeconds(1000);

• DateTimeOffset to Unix time in seconds:

long unixTimeStampInSeconds = dateTimeOffset.ToUnixTimeSeconds();

• Unix time in milliseconds to DateTimeOffset:

DateTimeOffset dateTimeOffset = DateTimeOffset.FromUnixTimeMilliseconds(1000000);

• DateTimeOffset to Unix time in milliseconds:

long unixTimeStampInMilliseconds= dateTimeOffset.ToUnixTimeMilliseconds();

Note: These methods convert to and from DateTimeOffset. To get a DateTime representation simply use the DateTimeOffset.DateTime property:

DateTime dateTime = dateTimeOffset.UtcDateTime;

To do this, you can set a callback function for the animate command which will execute after the scroll animation has finished.

For example:

var body = $("html, body");
body.stop().animate({scrollTop:0}, 500, 'swing', function() { 
   alert("Finished animating");
});

Where that alert code is, you can execute more javascript to add in further animation.

Also, the 'swing' is there to set the easing. Check out http://api.jquery.com/animate/ for more info.

If you just want to execute the shell command in your c program, you could use,

   #include <stdlib.h>

   int system(const char *command);

In your case,

system("pwd");

The issue is that there isn't an executable file called "pwd" and I'm unable to execute "echo $PWD", since echo is also a built-in command with no executable to be found.

What do you mean by this? You should be able to find the mentioned packages in /bin/

sudo find / -executable -name pwd
sudo find / -executable -name echo

You'll want to set a "list-style" via CSS, and give it a color: value. Example:

ul.colored {list-style: color: green;}

I have tried this and quite Simple process:

Created a new Package with required name--> Moved all my classes to this new package (Right click on previous package --> Refractor--> Move)

Well... assuming both arrays are of the same length, I would probably do something like this:

var newArr = []
for (var i = 0; i < array1.length; i++ {
    if (array1[i].id === array2[i].id) {
      newArr.push({id: array1[i].id, date: array1[i].date, name: array2[i].name});
  }
}

In conf directory of apache tomcat you can find context.xml file. In that edit tag as <Context reloadable="true">. this should solve the issue and you need not restart the server

In fact, most compilers emit the same code for both functions calls, because references are generally implemented using pointers.

Following this logic, when an argument of (non-const) reference type is used in the function body, the generated code will just silently operate on the address of the argument and it will dereference it. In addition, when a call to such a function is encountered, the compiler will generate code that passes the address of the arguments instead of copying their value.

Basically, references and pointers are not very different from an implementation point of view, the main (and very important) difference is in the philosophy: a reference is the object itself, just with a different name.

References have a couple more advantages compared to pointers (e. g. they can't be NULL, so they are safer to use). Consequently, if you can use C++, then passing by reference is generally considered more elegant and it should be preferred. However, in C, there's no passing by reference, so if you want to write C code (or, horribile dictu, code that compiles with both a C and a C++ compiler, albeit that's not a good idea), you'll have to restrict yourself to using pointers.

You can try this... put parameters as :

I am currently in Tokyo, and I used to be in Switzerland. Yet, my location until some days ago was not pinpinted exactly, except in the broad Tokyo area. Today I tried, and I appear to be in Switzerland. How?

Well the secret is that I am now connected through wireless, and my wireless router has been identified (thanks to association to other wifis around me at that time) in a very accurate area in Switzerland. Now, my wifi moved to Tokyo, but the queried system still thinks the wifi router is in Switzerland, because either it has no information about the additional wifis surrounding me right now, or it cannot sort out the conflicting info (namely, the specific info about my wifi router against my ip geolocation, which pinpoints me in the far east).

So, to answer your question, google, or someone for him, did "wardriving" around, mapping the wifi presence. Every time a query is performed to the system (probably in compliance with the W3C draft for the geolocation API) your computer sends the wifi identifiers it sees, and the system does two things:

1. queries its database if geolocation exists for some of the wifis you passed, and returns the "wardrived" position if found, eventually with triangulation if intensities are present. The more wifi networks around, the higher is the accuracy of the positioning.
2. adds additional networks you see that are currently not in the database to their database, so they can be reused later.

As you see, the system builds up by itself. The only thing you need is good seeding. After that, it extends in "50 meters chunks" (the range of a newly found wifi connection).

Of course, if you really want the system go banana, you can start exchanging wifi routers around the globe with fellow revolutionaries of the no-global-positioning movement.

Update:

I'm not sure when or if the license changed for the iText# library, but it is licensed under AGPL which means it must be licensed if included with a closed-source product. The question does not (currently) require free or open-source libraries. One should always investigate the license type of any library used in a project.

I have used iText# with success in .NET C# 3.5; it is a port of the open source Java library for PDF generation and it's free.

There is a NuGet package available for iTextSharp version 5 and the official developer documentation, as well as C# examples, can be found at itextpdf.com

I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));

while ((line = br.readLine()) != null) {

}

I hope this can help anyone who sees this post.

If your branch is behind by master then do:

git checkout master (you are switching your branch to master)
git pull 
git checkout yourBranch (switch back to your branch)
git merge master

After merging it, check if there is a conflict or not.
If there is NO CONFLICT then:

git push

If there is a conflict then fix your file(s), then:

git add yourFile(s)
git commit -m 'updating my branch'
git push

You should open text files using rU so newlines are properly transformed, see http://docs.python.org/library/functions.html#open. This way there's no need to check for \r\n.

Because the range for floats is greater than that of integers -- returning an integer could overflow

Try the file command with -i option.

-i option Causes the file command to output mime type strings rather than the more traditional human readable ones. Thus it may say text/plain; charset=us-ascii rather than ASCII text.

Think of it as enforcing Eager-Loading in a scenario where you sub-items would otherwise be lazy-loading.

The Query EF is sending to the database will yield a larger result at first, but on access no follow-up queries will be made when accessing the included items.

On the other hand, without it, EF would execute separte queries later, when you first access the sub-items.

The following answer could be helpful for the first part of your question:

Django: How can I call a view function from template?

Another option (especially if you're rolling you own class) is to use an int or a int64, and designate the lower four digits (or possibly even 2) as "right of the decimal point". So "on the edges" you'll need some "* 10000" on the way in and some "/ 10000" on the way out. This is the storage mechanism used by Microsoft's SQL Server, see http://msdn.microsoft.com/en-au/library/ms179882.aspx

The nicity of this is that all your summation can be done using (fast) integer arithmetic.

You have installed the library in a non-standard location ($HOME/zlib/). That means the compiler will not know where your header files are and you need to tell the compiler that.

You can add a path to the list that the compiler uses to search for header files by using the -I (upper-case i) option.

Also note that the LD_LIBRARY_PATH is for the run-time linker and loader, and is searched for dynamic libraries when attempting to run an application. To add a path for the build-time linker use the -L option.

All-together the command line should look like

$ c++ -I$HOME/zlib/include some_file.cpp -L$HOME/zlib/lib -lz

If you get that error message (Peer authentication failed for user (PG::Error)) when running unit tests, make sure the test database exists.

use android:layout_gravity instead of android:gravity

android:gravity sets the gravity of the content of the View its used on. android:layout_gravity sets the gravity of the View or Layout in its parent.

Two example works for me, for your reference.

Bitmap bitmap = Utils.decodeBase64(base64);
try {
    File file = new File(filePath);
    FileOutputStream fOut = new FileOutputStream(file);
    bitmap.compress(Bitmap.CompressFormat.PNG, 85, fOut);
    fOut.flush();
    fOut.close();
}
catch (Exception e) {
    e.printStackTrace();
    LOG.i(null, "Save file error!");
    return false;
}

and this one

Bitmap savePic = Utils.decodeBase64(base64);
File file = new File(filePath);
File path = new File(file.getParent());

if (savePic != null) {
    try {
        // build directory
        if (file.getParent() != null && !path.isDirectory()) {
            path.mkdirs();
        }
        // output image to file
        FileOutputStream fos = new FileOutputStream(filePath);
        savePic.compress(Bitmap.CompressFormat.PNG, 90, fos);
        fos.close();
        ret = true;
    } catch (Exception e) {
        e.printStackTrace();
    }
} else {
    LOG.i(TAG, "savePicture image parsing error");
}

Shared Preferences are the key/value pairs that we can store. They are internal type of storage which means we do not have to create an external database to store it. To see it go to, 1) Go to View in the menu bar. Select Tool Windows. 2) Click on Device File Explorer. 3) Device File Explorer opens up in the right hand side. 4) Find the data folder and click on it. 5) In the data folder, you can select another data folder. 6) Try to search for your package name in this data folder. Ex: com.example.com 7) Then Click on shared_prefs and open the .xml file.

Hope this helps!

Try putting this HTML snippet into your served document:

<img id="ItemPreview" src="">

Then, on JavaScript side, you can dynamically modify image's src attribute with so-called Data URL.

document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;

Alternatively, using jQuery:

$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);

This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..." part) in the URL accordingly.

While the above solutions do work, there is a very simple solution shall we say in "layman's" terms. Someone still learning python and string's can use the other answers but they don't really understand how they work or what each part of the code is doing without a full explanation by the poster as opposed to "this works". The following executes the swapping of every second character in a string and is easy for beginners to understand how it works.

It is simply iterating through the string (any length) by two's (starting from 0 and finding every second character) and then creating a new string (swapped_pair) by adding the current index + 1 (second character) and then the actual index (first character), e.g., index 1 is put at index 0 and then index 0 is put at index 1 and this repeats through iteration of string.

Also added code to ensure string is of even length as it only works for even length.

DrSanjay Bhakkad post above is also a good one that works for even or odd strings and is basically doing the same function as below.

string = "abcdefghijklmnopqrstuvwxyz123"

# use this prior to below iteration if string needs to be even but is possibly odd
if len(string) % 2 != 0:
    string = string[:-1]

# iteration to swap every second character in string
swapped_pair = ""
for i in range(0, len(string), 2):
    swapped_pair += (string[i + 1] + string[i])

# use this after above iteration for any even or odd length of strings
if len(swapped_pair) % 2 != 0:
    swapped_adj += swapped_pair[-1]

print(swapped_pair)

badcfehgjilknmporqtsvuxwzy213 # output if the "even or odd" code used

One problem is, that the compiler does not know, which kind of value is delivered by your function; is assumes, that the function returns an int in this case, but this can be as correct as it can be wrong. Another problem is, that the compiler does not know, which kind of arguments your function expects, and cannot warn you, if you are passing values of the wrong kind. There are special "promotion" rules, which apply when passing, say floating point values to an undeclared function (the compiler has to widen them to type double), which is often not, what the function actually expects, leading to hard to find bugs at run-time.

There are libraries that provide safe arithmetic operations, which check integer overflow/underflow . For example, Guava's IntMath.checkedAdd(int a, int b) returns the sum of a and b, provided it does not overflow, and throws ArithmeticException if a + b overflows in signed int arithmetic.

This is not an answer but option. I switched to https://github.com/joltup/rn-fetch-blob It works good both for form-data and files

If you want to show error messages on form submission, you can use condition form.$submitted to check if an attempt was made to submit the form. Check following example.

<form name="myForm" novalidate ng-submit="myForm.$valid && createUser()">
  <input type="text" name="name" ng-model="user.name" placeholder="Enter name of user" required>
  <div ng-messages="myForm.name.$error" ng-if="myForm.$submitted">
    <div ng-message="required">Please enter user name.</div>
  </div>

  <input type="text" name="address" ng-model="user.address" placeholder="Enter Address" required ng-maxlength="30">
  <div ng-messages="myForm.name.$error" ng-if="myForm.$submitted">
    <div ng-message="required">Please enter user address.</div>
    <div ng-message="maxlength">Should be less than 30 chars</div>
  </div>

  <button type="submit">
    Create user
  </button>
</form>

Add the below code from the resources tags in your pom.xml inside build tags. so it means resources tags must be inside of build tags in your pom.xml

<build>
    <resources>
        <resource>
            <directory>src/main/java/resources</directory>
                <filtering>true</filtering> 
         </resource>
     </resources>
<build/>

Did you try setting the style:

input {
    text-align:right;
}

Just tested, this works fine (in FF3 at least):

<html>
    <head>
        <title>Blah</title>
        <style type="text/css">
        input { text-align:right; }
        </style>
    </head>
    <body>
        <input type="text" value="2">
    </body>
</html>

You'll probably want to throw a class on these inputs, and use that class as the selector. I would shy away from "rightAligned" or something like that. In a class name, you want to describe what the element's function is, not how it should be rendered. "numeric" might be good, or perhaps the business function of the text boxes.

• All as varchar (they aren't numbers but "collections of digits")
• Country + area + number separately
• Not all countries have area code (eg Malta where I am)
• Some countries drop the leading zero from the area code when dialling internal (eg UK)
• Format in the client code

I have faced same issue in my application too. Without Modifiyig any Method information, I have provided [ActionName("SomeMeaningfulName")] on Action head. issue resolved

[ActionName("_EmployeeDetailsByModel")]
        public PartialViewResult _EmployeeDetails(Employee model)
        {
            // Some Operation                
                return PartialView(model);
            }
        }

[ActionName("_EmployeeDetailsByModelWithPagination")]
        public PartialViewResult _EmployeeDetails(Employee model,int Page,int PageSize)
        {

                // Some Operation
                return PartialView(model);

        }

Here's a one-line solution with mapfile:

$ mapfile -d $'\0' -t arr < <(printf '%s\0' "${arr[@]}" | grep -Pzv "<regexp>")

Example:

$ arr=("Adam" "Bob" "Claire"$'\n'"Smith" "David" "Eve" "Fred")

$ echo "Size: ${#arr[*]} Contents: ${arr[*]}"

Size: 6 Contents: Adam Bob Claire
Smith David Eve Fred

$ mapfile -d $'\0' -t arr < <(printf '%s\0' "${arr[@]}" | grep -Pzv "^Claire\nSmith$")

$ echo "Size: ${#arr[*]} Contents: ${arr[*]}"

Size: 5 Contents: Adam Bob David Eve Fred

This method allows for great flexibility by modifying/exchanging the grep command and doesn't leave any empty strings in the array.

Compile it as x64 with VS2005:

%llu works well.

You can do like this.

<input type="button" value="mybutton1" onclick="dosomething(this)">

function dosomething(element){
    alert("value is "+element.value); //you can print any value like id,class,value,innerHTML etc.
};

Combining solutions above when using express request:

let url=url.parse(req.originalUrl);
let page = url.parse(uri).path?url.parse(uri).path.match('^[^?]*')[0].split('/').slice(1)[0] : '';

this will handle all cases like

localhost/page
localhost:3000/page/
/page?item_id=1
localhost:3000/
localhost/

etc. Some examples:

> urls
[ 'http://localhost/page',
  'http://localhost:3000/page/',
  'http://localhost/page?item_id=1',
  'http://localhost/',
  'http://localhost:3000/',
  'http://localhost/',
  'http://localhost:3000/page#item_id=2',
  'http://localhost:3000/page?item_id=2#3',
  'http://localhost',
  'http://localhost:3000' ]
> urls.map(uri => url.parse(uri).path?url.parse(uri).path.match('^[^?]*')[0].split('/').slice(1)[0] : '' )
[ 'page', 'page', 'page', '', '', '', 'page', 'page', '', '' ]

For me the Issue was I didn't run the setup as Administrator, after running the setup as administrator the message go away and I was prompted to install and continue process.

Fill the entire screen

var body : some View{

A single pipe (|) is the bitwise OR operator.

Two pipes (||) is the logical OR operator.

They are not interchangeable.

The easiest way to solve this problem is add the following FTP information to your wp-config.php

define('FS_METHOD', 'direct');
define('FTP_BASE', '/usr/home/username/public_html/my-site.example.com/wordpress/');
define('FTP_CONTENT_DIR', '/usr/home/username/public_html/my-site.example.com/wordpress/wp-content/');
define('FTP_PLUGIN_DIR ', '/usr/home/username/public_html/my-site.example.com/wordpress/wp-content/plugins/');

FTP_BASE is the full path to the "base"(ABSPATH) folder of the WordPress installation FTP_CONTENT_DIR is the full path to the wp-content folder of the WordPress installation. FTP_PLUGIN_DIR is the full path to the plugins folder of the WordPress installation.

You have problem with like this: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

Ans: $ sudo service mysql start

I would say the answer is: you can't. (or at least: you shouldn't). This is not what Webpack is supposed to do. Webpack is a bundler, and it should not be used for other tasks (in this case: copying static files is another task). You should use a tool like Grunt or Gulp to do such tasks. It is very common to integrate Webpack as a Grunt task or as a Gulp task. They both have other tasks useful for copying files like you described, for example, grunt-contrib-copy or gulp-copy.

For other assets (not the index.html), you can just bundle them in with Webpack (that is exactly what Webpack is for). For example, var image = require('assets/my_image.png');. But I assume your index.html needs to not be a part of the bundle, and therefore it is not a job for the bundler.

var res = from s in Splitting 
          join c in Customer on s.CustomerId equals c.Id
         where c.Id == customrId
            && c.CompanyId == companyId
        select s;

Using Extension methods:

var res = Splitting.Join(Customer,
                 s => s.CustomerId,
                 c => c.Id,
                 (s, c) => new { s, c })
           .Where(sc => sc.c.Id == userId && sc.c.CompanyId == companId)
           .Select(sc => sc.s);

That is a C++ standard library header file for input output streams. It includes functionality to read and write from streams. You only need to include it if you wish to use streams.

In modern, supported browsers, you can simply do that in CSS with -

header{
  position: sticky;
  top: 0;
}

Note: The HTML structure is important while using position: sticky, since it's make the element sticky relative to the parent. And the sticky positioning might not work with a single element made sticky within a parent.

Run the snippet below to check a sample implementation.

main{_x000D_
padding: 0;_x000D_
}_x000D_

In Symfony 2 ( to be more specific, the 2.3 version ) you can get a data of an field by

$var = $form->get('yourformfieldname')->getData();

or you can get all data sent

$data = $form->getData();

where '$data' is an array containing your form fields' values.

Because you send custom headers so your CORS request is not a simple request, so the browser first sends a preflight OPTIONS request to check that the server allows your request.

If you turn on CORS on the server then your code will work. You can also use JavaScript fetch instead (here)

let url='https://server.test-cors.org/server?enable=true&status=200&methods=POST&headers=My-First-Header,My-Second-Header';_x000D_
_x000D_
_x000D_
$.ajax({_x000D_
    type: 'POST',_x000D_
    url: url,_x000D_
    headers: {_x000D_
        "My-First-Header":"first value",_x000D_
        "My-Second-Header":"second value"_x000D_
    }_x000D_
}).done(function(data) {_x000D_
    alert(data[0].request.httpMethod + ' was send - open chrome console> network to see it');_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Here is an example configuration which turns on CORS on nginx (nginx.conf file):

I think that what you want to do is turn the JSON string back into an object when it arrives back in your XMLHttpRequest - correct?

If so, you need to eval the string to turn it into a JavaScript object - note that this can be unsafe as you're trusting that the JSON string isn't malicious and therefore executing it. Preferably you could use jQuery's parseJSON

The is no API for adding a shortcut to the home screen in iOS, so no third-party browser is capable of providing that functionality.

Do you have an integer value in each row that you could pass as a seed to the RAND function?

To get an integer between 1 and 14 I believe this would work:

FLOOR( RAND(<yourseed>) * 14) + 1

For those who have a custom jQuery UI build (bower for ex.), add the effects core located in ..\jquery-ui\ui\effect.js.

-O3 option turns on more expensive optimizations, such as function inlining, in addition to all the optimizations of the lower levels ‘-O2’ and ‘-O1’. The ‘-O3’ optimization level may increase the speed of the resulting executable, but can also increase its size. Under some circumstances where these optimizations are not favorable, this option might actually make a program slower.

The real question is: whether to use interfaces or base classes. This has been covered before.

In C#, an abstract class (one marked with the keyword "abstract") is simply a class from which you cannot instantiate objects. This serves a different purpose than simply making the distinction between base classes and interfaces.

_{I can see many answers showing how to solve problem, but only Stephen's answer is trying to explain why problem occurs so I will try to add something more on this subject. It is a story about possible reasons why Object[] toArray wasn't changed to T[] toArray where generics ware introduced to Java.}

Why String[] stockArr = (String[]) stock_list.toArray(); wont work?

In Java, generic type exists at compile-time only. At runtime information about generic type (like in your case <String>) is removed and replaced with Object type (take a look at type erasure). That is why at runtime toArray() have no idea about what precise type to use to create new array, so it uses Object as safest type, because each class extends Object so it can safely store instance of any class.

Now the problem is that you can't cast instance of Object[] to String[].

Why? Take a look at this example (lets assume that class B extends A):

//B extends A
A a = new A();
B b = (B)a;

Although such code will compile, at runtime we will see thrown ClassCastException because instance held by reference a is not actually of type B (or its subtypes). Why is this problem (why this exception needs to be cast)? One of the reasons is that B could have new methods/fields which A doesn't, so it is possible that someone will try to use these new members via b reference even if held instance doesn't have (doesn't support) them. In other words we could end up trying to use data which doesn't exist, which could lead to many problems. So to prevent such situation JVM throws exception, and stop further potentially dangerous code.

You could ask now "So why aren't we stopped even earlier? Why code involving such casting is even compilable? Shouldn't compiler stop it?". Answer is: no because compiler can't know for sure what is the actual type of instance held by a reference, and there is a chance that it will hold instance of class B which will support interface of b reference. Take a look at this example:

A a = new B(); 
      //  ^------ Here reference "a" holds instance of type B
B b = (B)a;    // so now casting is safe, now JVM is sure that `b` reference can 
               // safely access all members of B class

Now lets go back to your arrays. As you see in question, we can't cast instance of Object[] array to more precise type String[] like

Object[] arr = new Object[] { "ab", "cd" };
String[] arr2 = (String[]) arr;//ClassCastException will be thrown

Here problem is a little different. Now we are sure that String[] array will not have additional fields or methods because every array support only:

• [] operator,
• length filed,
• methods inherited from Object supertype,

So it is not arrays interface which is making it impossible. Problem is that Object[] array beside Strings can store any objects (for instance Integers) so it is possible that one beautiful day we will end up with trying to invoke method like strArray[i].substring(1,3) on instance of Integer which doesn't have such method.

So to make sure that this situation will never happen, in Java array references can hold only

• instances of array of same type as reference (reference String[] strArr can hold String[])
• instances of array of subtype (Object[] can hold String[] because String is subtype of Object),

but can't hold

• array of supertype of type of array from reference (String[] can't hold Object[])
• array of type which is not related to type from reference (Integer[] can't hold String[])

In other words something like this is OK

Object[] arr = new String[] { "ab", "cd" }; //OK - because
               //  ^^^^^^^^                  `arr` holds array of subtype of Object (String)
String[] arr2 = (String[]) arr; //OK - `arr2` reference will hold same array of same type as 
                                //     reference

You could say that one way to resolve this problem is to find at runtime most common type between all list elements and create array of that type, but this wont work in situations where all elements of list will be of one type derived from generic one. Take a look

//B extends A
List<A> elements = new ArrayList<A>();
elements.add(new B());
elements.add(new B());

now most common type is B, not A so toArray()

A[] arr = elements.toArray();

would return array of B class new B[]. Problem with this array is that while compiler would allow you to edit its content by adding new A() element to it, you would get ArrayStoreException because B[] array can hold only elements of class B or its subclass, to make sure that all elements will support interface of B, but instance of A may not have all methods/fields of B. So this solution is not perfect.

Best solution to this problem is explicitly tell what type of array toArray() should be returned by passing this type as method argument like

String[] arr = list.toArray(new String[list.size()]);

or

String[] arr = list.toArray(new String[0]); //if size of array is smaller then list it will be automatically adjusted.

There's a problem with ef seeding db from Startup.Configure in 2.0 ... you can still do it with this work around. Tested and worked fine

Edit

Okay, complete re-write. It's been a while, I've learned a bit and the comments have helped.

Node.prototype.hasClass = function (className) {
    if (this.classList) {
        return this.classList.contains(className);
    } else {
        return (-1 < this.className.indexOf(className));
    }
};

Node.prototype.addClass = function (className) {
    if (this.classList) {
        this.classList.add(className);
    } else if (!this.hasClass(className)) {
        var classes = this.className.split(" ");
        classes.push(className);
        this.className = classes.join(" ");
    }
    return this;
};

Node.prototype.removeClass = function (className) {
    if (this.classList) {
        this.classList.remove(className);
    } else {
        var classes = this.className.split(" ");
        classes.splice(classes.indexOf(className), 1);
        this.className = classes.join(" ");
    }
    return this;
};

// Some browsers don't have a native trim() function
if(!String.prototype.trim) {
    Object.defineProperty(String.prototype,'trim', {
        value: function() {
            return this.replace(/^\s+|\s+$/g,'');
        },
        writable:false,
        enumerable:false,
        configurable:false
    });
}
// addClass()
// first checks if the class name already exists, if not, it adds the class.
Object.defineProperty(Node.prototype,'addClass', {
    value: function(c) {
        if(this.className.indexOf(c)<0) {
            this.className=this.className+=' '+c;
        }
        return this;
    },
    writable:false,
    enumerable:false,
    configurable:false
});
// removeClass()
// removes the class and cleans up the className value by changing double 
// spacing to single spacing and trimming any leading or trailing spaces
Object.defineProperty(Node.prototype,'removeClass', {
    value: function(c) {
        this.className=this.className.replace(c,'').replace('  ',' ').trim();
        return this;
    },
    writable:false,
    enumerable:false,
    configurable:false
});

Now you can call myElement.removeClass('myClass')

or chain it: myElement.removeClass("oldClass").addClass("newClass");

Place the logo in your public folder under e.g. public/img/logo.png and then refer to the public folder as %PUBLIC_URL%:

<img src="%PUBLIC_URL%/img/logo.png"/>

The use of %PUBLIC_URL% in the above will be replaced with the URL of the public folder during the build. Only files inside the public folder can be referenced from the HTML.

Unlike "/img/logo.png" or "logo.png", "%PUBLIC_URL%/img/logo.png" will work correctly both with client-side routing and a non-root public URL. Learn how to configure a non-root public URL by running npm run build.

I was searching for a simple solution without window focus. Jayk's answer, pynput, works perfect for me. Here is the example how I use it.

from pynput import keyboard

def on_press(key):
    if key == keyboard.Key.esc:
        return False  # stop listener
    try:
        k = key.char  # single-char keys
    except:
        k = key.name  # other keys
    if k in ['1', '2', 'left', 'right']:  # keys of interest
        # self.keys.append(k)  # store it in global-like variable
        print('Key pressed: ' + k)
        return False  # stop listener; remove this if want more keys

listener = keyboard.Listener(on_press=on_press)
listener.start()  # start to listen on a separate thread
listener.join()  # remove if main thread is polling self.keys

Most of the time when we download tomcat and extract the file a folder will be created:

C:\Program Files\apache-tomcat-9.0.1-windows-x64

Inside that actual tomcat folder will be there:

C:\Program Files\apache-tomcat-9.0.1-windows-x64\apache-tomcat-9.0.1

so while selecting you need to select inner folder:

C:\Program Files\apache-tomcat-9.0.1-windows-x64\apache-tomcat-9.0.1

instead of the outer.

If you have TortoiseSVN then you can CTRL click the two files to select them in Windows Explorer and then right-click, TortoiseSVN->Diff.

This works particularly well if you are looking for a small change in a large data set.

I believe that, if you need to use the %20 variant, you could perhaps use rawurlencode().

You can use parseInt(jQuery.offset().top) to always use the Integer (primitive - int) value across all browsers.

I did most of the suggested stuff here, still didnt work. Tried this and it worked: Open your XAMPP Control Panel, locate the Config button for the Apache module. Click on the Config button and Select PHP (php.ini). Open with any text editor and remove the semi-column before php_openssl. Save and Restart Apache. That should do!

Bootstrap 2 CSS solution:

.collapse {  transition: height 0.01s; }  

NB: setting transition: none disables the collapse functionnality.

Bootstrap 4 solution:

.collapsing {
  transition: none !important;
}

Prints all the rows with NA data:

tmp <- data.frame(c(1,2,3),c(4,NA,5));
tmp[round(which(is.na(tmp))/ncol(tmp)),]

The answer posted by @m0nhawk doesn't seem to work as I test on a Windows 7 machine. Instead, using the following scripts would export/import the settings of putty:

::export
@echo off
set regfile=putty.reg
pushd %~dp0

reg export HKCU\Software\SimonTatham %regfile% /y

popd

--

::import
@echo off
pushd %~dp0
set regfile=putty.reg

if exist %regfile% reg import %regfile%

popd

First the CSS - tweak this however you like:

a.selected {
  background-color:#1F75CC;
  color:white;
  z-index:100;
}

.messagepop {
  background-color:#FFFFFF;
  border:1px solid #999999;
  cursor:default;
  display:none;
  margin-top: 15px;
  position:absolute;
  text-align:left;
  width:394px;
  z-index:50;
  padding: 25px 25px 20px;
}

label {
  display: block;
  margin-bottom: 3px;
  padding-left: 15px;
  text-indent: -15px;
}

.messagepop p, .messagepop.div {
  border-bottom: 1px solid #EFEFEF;
  margin: 8px 0;
  padding-bottom: 8px;
}

And the JavaScript:

function deselect(e) {
  $('.pop').slideFadeToggle(function() {
    e.removeClass('selected');
  });    
}

$(function() {
  $('#contact').on('click', function() {
    if($(this).hasClass('selected')) {
      deselect($(this));               
    } else {
      $(this).addClass('selected');
      $('.pop').slideFadeToggle();
    }
    return false;
  });

  $('.close').on('click', function() {
    deselect($('#contact'));
    return false;
  });
});

$.fn.slideFadeToggle = function(easing, callback) {
  return this.animate({ opacity: 'toggle', height: 'toggle' }, 'fast', easing, callback);
};

And finally the html:

<div class="messagepop pop">
  <form method="post" id="new_message" action="/messages">
    <p><label for="email">Your email or name</label><input type="text" size="30" name="email" id="email" /></p>
    <p><label for="body">Message</label><textarea rows="6" name="body" id="body" cols="35"></textarea></p>
    <p><input type="submit" value="Send Message" name="commit" id="message_submit"/> or <a class="close" href="/">Cancel</a></p>
  </form>
</div>

<a href="/contact" id="contact">Contact Us</a>

Here is a jsfiddle demo and implementation.

Depending on the situation you may want to load the popup content via an ajax call. It's best to avoid this if possible as it may give the user a more significant delay before seeing the content. Here couple changes that you'll want to make if you take this approach.

HTML becomes:

<div>
    <div class="messagepop pop"></div> 
    <a href="/contact" id="contact">Contact Us</a>
</div>

And the general idea of the JavaScript becomes:

$("#contact").on('click', function() {
    if($(this).hasClass("selected")) {
        deselect();               
    } else {
        $(this).addClass("selected");
        $.get(this.href, function(data) {
            $(".pop").html(data).slideFadeToggle(function() { 
                $("input[type=text]:first").focus();
            });
        }
    }
    return false;
});

Yes you understood it correctly, the function password_hash() will generate a salt on its own, and includes it in the resulting hash-value. Storing the salt in the database is absolutely correct, it does its job even if known.

// Hash a new password for storing in the database.
// The function automatically generates a cryptographically safe salt.
$hashToStoreInDb = password_hash($_POST['password'], PASSWORD_DEFAULT);

// Check if the hash of the entered login password, matches the stored hash.
// The salt and the cost factor will be extracted from $existingHashFromDb.
$isPasswordCorrect = password_verify($_POST['password'], $existingHashFromDb);

The second salt you mentioned (the one stored in a file), is actually a pepper or a server side key. If you add it before hashing (like the salt), then you add a pepper. There is a better way though, you could first calculate the hash, and afterwards encrypt (two-way) the hash with a server-side key. This gives you the possibility to change the key when necessary.

In contrast to the salt, this key should be kept secret. People often mix it up and try to hide the salt, but it is better to let the salt do its job and add the secret with a key.

The following code should work:

$('#reportrange').daterangepicker({
                startDate: start,
                endDate: end,
                ranges: {
                    'Hoy': [moment(), moment()],
                    'Ayer': [moment().subtract(1, 'days'), moment().subtract(1, 'days')],
                    'Ultimos 7 dias': [moment().subtract(6, 'days'), moment()],
                    'Ultimos 30 dias': [moment().subtract(29, 'days'), moment()],
                    'Mes actual': [moment().startOf('month'), moment().endOf('month')],
                    'Ultimo mes': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')],
                    'Enero': [moment().month(0).startOf('month') , moment().month(0).endOf('month')],
                    'Febrero': [moment().month(1).startOf('month') , moment().month(1).endOf('month')],
                    'Marzo': [moment().month(2).startOf('month') , moment().month(2).endOf('month')],
                    'Abril': [moment().month(3).startOf('month') , moment().month(3).endOf('month')],

Opt 1: using toLowerCase()

var x = 'ABC';
x = x.toLowerCase();

Opt 2: Using your own function

function convertToLowerCase(str) {
  var result = '';

  for (var i = 0; i < str.length; i++) {
    var code = str.charCodeAt(i);
    if (code > 64 && code < 91) {
      result += String.fromCharCode(code + 32);
    } else {
      result += str.charAt(i);
    }
  }
  return result;
}

Call it as:

x = convertToLowerCase(x);

A timer is a better idea, IMO. That way, if your service is asked to stop, it can respond to that very quickly, and just not call the timer tick handler again... if you're sleeping, the service manager will either have to wait 50 seconds or kill your thread, neither of which is terribly nice.

First make sure you have installed git scm or not. If not, here's the link for windows: https://git-for-windows.github.io/ Then go to Android studio and configure the link of Git to the place where you installed your git(probably in C:/program files) I referred to a YouTube video to solve my issue. You can refer it here: https://www.youtube.com/watch?v=faEd2syXypE

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

You can use android:fillViewport="true" to make NestedScrollView measure the RecyclerView. The RecyclerView will fill the remaining height. so if you want to scroll the NestScrollView, you can set the RecyclerView's minHeight.

string inputString = "2000-02-02";
DateTime dDate;

if (DateTime.TryParse(inputString, out dDate))
{
    String.Format("{0:d/MM/yyyy}", dDate); 
}
else
{
    Console.WriteLine("Invalid"); // <-- Control flow goes here
}

$('li.menu.active')

is the simplest way. This will return all elements with both classes.

Or an already answered jQuery hasClass() - check for more than one class

Executing seq(1, 10, 1) does what 1:10 does. You can change the last parameter of seq, i.e. by, to be the step of whatever size you like.

> [1]  0  2  4  6  8 10

Based on http://code.msdn.microsoft.com/101-LINQ-Samples-3fb9811b,

EqualAll is the approach that best meets your needs.

public void Linq96() 
{ 
    var wordsA = new string[] { "cherry", "apple", "blueberry" }; 
    var wordsB = new string[] { "cherry", "apple", "blueberry" }; 

    bool match = wordsA.SequenceEqual(wordsB); 

    Console.WriteLine("The sequences match: {0}", match); 
} 

It seems to work if you use

div#scrollable {
    overflow-y: scroll;
    height: 100%;
}

and add padding-bottom: 60px to div.sidebar.

For example: http://jsfiddle.net/AKL35/6/

However, I am unsure why it must be 60px.

Also, you missed the f from overflow-y: scroll;

For Spring 4, using Spring Boot we can have the following example without using the anti-pattern of getting the Bean from the ApplicationContext directly:

package com.yourproject;

@SpringBootApplication
public class TestBed implements CommandLineRunner {

    private MyService myService;

    @Autowired
    public TestBed(MyService myService){
        this.myService = myService;
    }

    public static void main(String... args) {
        SpringApplication.run(TestBed.class, args);
    }

    @Override
    public void run(String... strings) throws Exception {
        System.out.println("myService: " + MyService );
    }

}

@Service 
public class MyService{
    public String getSomething() {
        return "something";
    }
}

Make sure that all your injected services are under com.yourproject or its subpackages.

Appending a single scalar could be done a bit easier as already shown (and also without converting to float) by expanding the scalar to a python-list-type:

import numpy as np
a = np.array([[1,3,4],[1,2,3],[1,2,1]])
x = 10

b = np.hstack ((a, [[x]] * len (a) ))

returns b as:

array([[ 1,  3,  4, 10],
       [ 1,  2,  3, 10],
       [ 1,  2,  1, 10]])

Appending a row could be done by:

c = np.vstack ((a, [x] * len (a[0]) ))

returns c as:

array([[ 1,  3,  4],
       [ 1,  2,  3],
       [ 1,  2,  1],
       [10, 10, 10]])

You can do it in 3 lines using basic math - in my example I used multiplication, but simple addition would work also.

float startAngle = 159.9F;
float stopAngle = 355.87F;

startAngle = startAngle * stopAngle;
stopAngle = startAngle / stopAngle;
startAngle = startAngle / stopAngle;

Edit: As noted in the comments, this wouldn't work if y = 0 as it would generate a divide by zero error which I hadn't considered. So the +/- solution alternatively presented would be the best way to go.

</deprecated>

To keep my code immediately comprehensible, I'd be more likely to do something like this. [Always think about the poor guy that's gonna have to maintain your code]:

static bool Swap<T>(ref T x, ref T y)
{
    try
    {
        T t = y;
        y = x;
        x = t;
        return true;
    }
    catch
    {
        return false;
    }
}

And then you can do it in one line of code:

float startAngle = 159.9F
float stopAngle = 355.87F
Swap<float>(ref startAngle, ref stopAngle);

Or...

MyObject obj1 = new MyObject("object1");
MyObject obj2 = new MyObject("object2");
Swap<MyObject>(ref obj1, ref obj2);

Done like dinner...you can now pass in any type of object and switch them around...

you can simply try this. it will return you current machine time

var _d = new Date(), t = 0, d = new Date(t*1000 + _d.getTime())

What do you think? Is it fine to remove them? Or would you keep them for increased "correctness"?

It is fine to remove them. Using return is exactly the scenario where break should not be used.

In your index.html, copy and paste the ga snippet but remove the line ga('send', 'pageview');

  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');
  ga('create', 'UA-XXXXXXXX-X');
</script>

I like to give it it's own factory file my-google-analytics.js with self injection:

angular.module('myApp')
  .factory('myGoogleAnalytics', [
    '$rootScope', '$window', '$location', 
    function ($rootScope, $window, $location) {

      var myGoogleAnalytics = {};

      /**
       * Set the page to the current location path
       * and then send a pageview to log path change.
       */
      myGoogleAnalytics.sendPageview = function() {
        if ($window.ga) {
          $window.ga('set', 'page', $location.path());
          $window.ga('send', 'pageview');
        }
      }

      // subscribe to events
      $rootScope.$on('$viewContentLoaded', myGoogleAnalytics.sendPageview);

      return myGoogleAnalytics;
    }
  ])
  .run([
    'myGoogleAnalytics', 
    function(myGoogleAnalytics) {
        // inject self
    }
  ]);

Only Visual Studio 2015 Enterprise has code coverage built-in. See the feature matrix for details.

You can use the OpenCover.UI extension for code coverage check inside Visual Studio. It supports MSTest, nUnit, and xUnit.

The new version can be downloaded from here (release notes).

The best way is to do a mongodump then mongorestore. You can select the collection via:

mongodump -d some_database -c some_collection

[Optionally, zip the dump (zip some_database.zip some_database/* -r) and scp it elsewhere]

Then restore it:

mongorestore -d some_other_db -c some_or_other_collection dump/some_collection.bson

Existing data in some_or_other_collection will be preserved. That way you can "append" a collection from one database to another.

Prior to version 2.4.3, you will also need to add back your indexes after you copy over your data. Starting with 2.4.3, this process is automatic, and you can disable it with --noIndexRestore.

You're overcomplicating things:

var e = $('<div style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
e.attr('id', 'myid');
$('#box').append(e);

The simplest answer to this problem is specifying the correct path to flask in your environment. Make sure the script you are running knows how to get to the flask installation. Using print(sys.path) as mentioned above certainly helped to figure out the path(s) the script was using.

Use -qscale:v to control quality

Use -qscale:v (or the alias -q:v) as an output option.

• Normal range for JPEG is 2-31 with 31 being the worst quality.
• The scale is linear with double the qscale being roughly half the bitrate.
• Recommend trying values of 2-5.
• You can use a value of 1 but you must add the -qmin 1 output option (because the default is -qmin 2).

To output a series of images:

ffmpeg -i input.mp4 -qscale:v 2 output_%03d.jpg

See the image muxer documentation for more options involving image outputs.

To output a single image at ~60 seconds duration:

ffmpeg -ss 60 -i input.mp4 -qscale:v 4 -frames:v 1 output.jpg

In events handler you can get id as follows

function show(btn) {_x000D_
  console.log('Button id:',btn.id);_x000D_
}

<button id="myButtonId" onclick="show(this)">Click me</button>

Another way to extend (specifically meaning, add new methods, not change existing ones) classes, even built-in ones, is to use a preprocessor that adds the ability to extend out of/above the scope of Python itself, converting the extension to normal Python syntax before Python actually gets to see it.

I've done this to extend Python 2's str() class, for instance. str() is a particularly interesting target because of the implicit linkage to quoted data such as 'this' and 'that'.

Here's some extending code, where the only added non-Python syntax is the extend:testDottedQuad bit:

extend:testDottedQuad
def testDottedQuad(strObject):
    if not isinstance(strObject, basestring): return False
    listStrings = strObject.split('.')
    if len(listStrings) != 4: return False
    for strNum in listStrings:
        try:    val = int(strNum)
        except: return False
        if val < 0: return False
        if val > 255: return False
    return True

After which I can write in the code fed to the preprocessor:

if '192.168.1.100'.testDottedQuad():
    doSomething()

dq = '216.126.621.5'
if not dq.testDottedQuad():
    throwWarning();

dqt = ''.join(['127','.','0','.','0','.','1']).testDottedQuad()
if dqt:
    print 'well, that was fun'

The preprocessor eats that, spits out normal Python without monkeypatching, and Python does what I intended it to do.

Just as a c preprocessor adds functionality to c, so too can a Python preprocessor add functionality to Python.

My preprocessor implementation is too large for a stack overflow answer, but for those who might be interested, it is here on GitHub.

Check that you have the correct rights set on CA certificates bundle. Usually, that means read access for everyone to CA files in the /etc/ssl/certs directory, for instance /etc/ssl/certs/ca-certificates.crt.

You can see what files have been configured for you curl version with the

curl-config --configure

$ curl-config --configure

 'CPPFLAGS=-D_FORTIFY_SOURCE=2'

Here you need read access to /etc/ssl/certs/ca-certificates.crt

$ curl-config --configure
 '--build' 'i486-linux-gnu' 
 '--prefix=/usr' 
 '--mandir=/usr/share/man' 
 '--disable-dependency-tracking'

Great news, the fix is coming in March 2018, see this link: https://developers.google.com/web/updates/2018/01/devtools

"Local Overrides let you make changes in DevTools, and keep those changes across page loads. Previously, any changes that you made in DevTools would be lost when you reloaded the page. Local Overrides work for most file types

How it works:

• You specify a directory where DevTools should save changes. When you make changes in DevTools, DevTools saves a copy of the modified file to your directory.
• When you reload the page, DevTools serves the local, modified file, rather than the network resource.

To set up Local Overrides:

1. Open the Sources panel.
2. Open the Overrides tab.
3. Click Setup Overrides.
4. Select which directory you want to save your changes to.
5. At the top of your viewport, click Allow to give DevTools read and write access to the directory.
6. Make your changes."

    String s = "Hello";
    int i = 0;
    String g;
    if (s instanceof java.lang.String) {
       // This is going to be printed
       System.out.println("s is a String");
    }
    if (i instanceof Integer) {
       // This is going to be printed as autoboxing will happen (int -> Integer)
       System.out.println("i is an Integer");
    }
    if (g instanceof java.lang.String) {
       // This case is not going to happen because g is not initialized and
       // therefore is null and instanceof returns false for null. 
       System.out.println("g is a String");

Supplemental answer with Swift code

Quartz 2D graphics use a coordinate system with the origin in the bottom left while UIKit in iOS uses a coordinate system with the origin at the top left. Everything usually works fine but when doing some graphics operations, you have to modify the coordinate system yourself. The documentation states:

Some technologies set up their graphics contexts using a different default coordinate system than the one used by Quartz. Relative to Quartz, such a coordinate system is a modified coordinate system and must be compensated for when performing some Quartz drawing operations. The most common modified coordinate system places the origin in the upper-left corner of the context and changes the y-axis to point towards the bottom of the page.

This phenomenon can be seen in the following two instances of custom views that draw an image in their drawRect methods.

On the left side, the image is upside-down and on the right side the coordinate system has been translated and scaled so that the origin is in the top left.

Upside-down image

override func drawRect(rect: CGRect) {

    // image
    let image = UIImage(named: "rocket")!
    let imageRect = CGRect(x: 0, y: 0, width: image.size.width, height: image.size.height)

    // context
    let context = UIGraphicsGetCurrentContext()

    // draw image in context
    CGContextDrawImage(context, imageRect, image.CGImage)

Modified coordinate system

override func drawRect(rect: CGRect) {

    // image
    let image = UIImage(named: "rocket")!
    let imageRect = CGRect(x: 0, y: 0, width: image.size.width, height: image.size.height)

    // context
    let context = UIGraphicsGetCurrentContext()

    // save the context so that it can be undone later
    CGContextSaveGState(context)

    // put the origin of the coordinate system at the top left
    CGContextTranslateCTM(context, 0, image.size.height)
    CGContextScaleCTM(context, 1.0, -1.0)

    // draw the image in the context
    CGContextDrawImage(context, imageRect, image.CGImage)

    // undo changes to the context
    CGContextRestoreGState(context)
}

Maybe you just copied tree of folder and trying to add lowest one.

       subfolder2   (here you get an error)

in that case you have to commit directory on the upper level.

You should put a padding in each object. For example, you want a space between images, you can use the following:

img{
   padding: 5px;
}

That means 5px paddin for ALL sides. Read more at http://www.w3schools.com/css/css_padding.asp. By the way, studying a lot before attempting to program will make things easier for you (and for us).

There is only one basic type of Stream. However in various circumstances some members will throw an exception when called because in that context the operation was not available.

For example a MemoryStream is simply a way to moves bytes into and out of a chunk of memory. Hence you can call Read and Write on it.

On the other hand a FileStream allows you to read or write (or both) from/to a file. Whether you can actually Read or Write depends on how the file was opened. You can't Write to a file if you only opened it for Read access.
