That's the function I wrote to get string in Unicode characters:

function nbUnicodeLength(string){
    var stringIndex = 0;
    var unicodeIndex = 0;
    var length = string.length;
    var second;
    var first;
    while (stringIndex < length) {

        first = string.charCodeAt(stringIndex);  // returns an integer between 0 and 65535 representing the UTF-16 code unit at the given index.
        if (first >= 0xD800 && first <= 0xDBFF && string.length > stringIndex + 1) {
            second = string.charCodeAt(stringIndex + 1);
            if (second >= 0xDC00 && second <= 0xDFFF) {
                stringIndex += 2;
            } else {
                stringIndex += 1;
            }
        } else {
            stringIndex += 1;
        }

        unicodeIndex += 1;
    }
    return unicodeIndex;
}

Couldn't find a working answer here; but on linux you can run "umount.nfs4 /volume -f" and it definitely unmounts it.

Note that sometimes you will want to use the class type name inside its own definition, for example when using Python Typing module, e.g.

class Tree:
    def __init__(self, left: Tree, right: Tree):
        self.left = left
        self.right = right

This will also result in

NameError: name 'Tree' is not defined

That's because the class has not been defined yet at this point. The workaround is using so called Forward Reference, i.e. wrapping a class name in a string, i.e.

class Tree:
    def __init__(self, left: 'Tree', right: 'Tree'):
        self.left = left
        self.right = right

another possible solution:

public enum @base
{
    x,
    y,
    z
}

public enum consume
{
    x = @base.x,
    y = @base.y,
    z = @base.z,

    a,b,c
}

// TODO: Add a unit-test to check that if @base and consume are aligned

HTH

All you have to do is wrap your content inside a Grid Container tag, specify the spacing, then wrap the actual content inside a Grid Item tag.

 <Grid container spacing={24}>
    <Grid item xs={8}>
      <leftHeaderContent/>
    </Grid>

    <Grid item xs={3}>
      <rightHeaderContent/>
    </Grid>
  </Grid>

Also, I've struggled with material grid a lot, I suggest you checkout flexbox which is built into CSS automatically and you don't need any addition packages to use. Its very easy to learn.

https://css-tricks.com/snippets/css/a-guide-to-flexbox/

webview.loadDataWithBaseURL(null, text, "text/html", "UTF-8", null);

Add done as a parameter in default function. That will do.

Try using --debug

Useful if you're trying to get the right path to an include or source data file.

You can map JSON to specific class in Groovy using as operator:

import groovy.json.JsonSlurper

String json = '''
{
  "name": "John",  
  "age": 20
}
'''

def person = new JsonSlurper().parseText(json) as Person 

with(person) {
    assert name == 'John'
    assert age == 20
}

In SQL Server Management Studio, go to Object Explorer > (your server) > Security > Logins and right-click New Login:

Then in the dialog box that pops up, pick the types of objects you want to see (Groups is disabled by default - check it!) and pick the location where you want to look for your objects (e.g. use Entire Directory) and then find your AD group.

You now have a regular SQL Server Login - just like when you create one for a single AD user. Give that new login the permissions on the databases it needs, and off you go!

Any member of that AD group can now login to SQL Server and use your database.

Rewriting a file in place is often done by saving the old copy with a modified name. Unix folks add a ~ to mark the old one. Windows folks do all kinds of things -- add .bak or .old -- or rename the file entirely or put the ~ on the front of the name.

import shutil
shutil.move( afile, afile+"~" )

destination= open( aFile, "w" )
source= open( aFile+"~", "r" )
for line in source:
    destination.write( line )
    if <some condition>:
        destination.write( >some additional line> + "\n" )
source.close()
destination.close()

Instead of shutil, you can use the following.

import os
os.rename( aFile, aFile+"~" )

Try this

for(int i = 0; i != 5; ++i, ++j)
    do_something(i,j);

HTML ... tag can do that itself i.e. no PHP or java.

or see this post for complete detail on the above (with all options..).

Note that the % syntax for formatting strings is becoming outdated. If your version of Python supports it, you should write:

instr = "'{0}', '{1}', '{2}', '{3}', '{4}', '{5}', '{6}'".format(softname, procversion, int(percent), exe, description, company, procurl)

This also fixes the error that you happened to have.

Matter of style, but as Matt said, definitely consider marking constructors with default arguments which would allow implicit conversion as 'explicit' to avoid unintended automatic conversion. It's not a requirement (and may not be preferable if you're making a wrapper class which you want to implicitly convert to), but it can prevent errors.

I personally like defaults when appropriate, because I dislike repeated code. YMMV.

Adding this piece of code after the val() seems to work:

$(":input#single").trigger('change');

My class for show DatePicker. I can use for EditText, TextView or Button

import android.app.DatePickerDialog;
import android.content.Context;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TextView;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.TimeZone;

public class TextViewDatePicker
        implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
    public static final String DATE_SERVER_PATTERN = "yyyy-MM-dd";
    private DatePickerDialog mDatePickerDialog;
    private TextView mView;
    private Context mContext;
    private long mMinDate;
    private long mMaxDate;

    public TextViewDatePicker(Context context, TextView view) {
        this(context, view, 0, 0);
    }

    public TextViewDatePicker(Context context, TextView view, long minDate, long maxDate) {
        mView = view;
        mView.setOnClickListener(this);
        mView.setFocusable(false);

        mContext = context;
        mMinDate = minDate;
        mMaxDate = maxDate;
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.YEAR, year);
        calendar.set(Calendar.MONTH, monthOfYear);
        calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        Date date = calendar.getTime();

        SimpleDateFormat formatter = new SimpleDateFormat(DATE_SERVER_PATTERN);
        mView.setText(formatter.format(date));
    }

    @Override
    public void onClick(View v) {
        Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
        mDatePickerDialog = new DatePickerDialog(mContext, this, calendar.get(Calendar.YEAR),
                calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
        if (mMinDate != 0) {
            mDatePickerDialog.getDatePicker().setMinDate(mMinDate);
        }
        if (mMaxDate != 0) {
            mDatePickerDialog.getDatePicker().setMaxDate(mMaxDate);
        }
        mDatePickerDialog.show();
    }

    public DatePickerDialog getDatePickerDialog() {
        return mDatePickerDialog;
    }

    public void setMinDate(long minDate) {
        mMinDate = minDate;
    }

    public void setMaxDate(long maxDate) {
        mMaxDate = maxDate;
    }
}

Using

EditText myEditText = findViewById(R.id.myEditText);
TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText, minDate, maxDate);
//TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText); //without min date, max date

You can't call a non-static method from a static method, because the definition of "non-static" means something that is associated with an instance of the class. You don't have an instance of the class in a static context.

You can do almost the same yourself. Open Environment Variables and click "New" Button in the "User Variables for ..." .
Variable Name: ~
Variable Value: Click "Browse Directory..." button and choose a directory which you want.

And after this, open cmd and type this:
cd %~%
. It works.

Try following these steps:

1. Add the integratedSecurity=true to JDBC URL like this:

   Url: jdbc:sqlserver://<<Server>>:<<Port>>;databasename=<<DatabaseName>>;integratedsecurity=true 
   

2. Make sure to add the sqljdbc driver 4 or above version (sqljdbc.jar) in your project build path:

   java.sql.DatabaseMetaData metaData = connection.getMetaData();
   System.out.println("Driver version:" + metaData.getDriverVersion());
   

3. Add the VM argument for your project:

   • Find the sqljdbc_auth.dll file from DB installed server (C:\Program Files\sqljdbc_4.0\enu\auth\x86), or download from this link.

   • Place the dll file in your project folder and specify the VM argument like this: VM Argument: -Djava.library.path="<<DLL File path till folder>>"

     NOTE: Check your java version 32/64 bit then add 32/64 bit version dll file accordingly.

They dropped XS because Bootstrap is considered a mobile-first development tool. It's default is considered xs and so doesn't need to be defined.

On IE11 the onfocus event is called twice, thus the user is prompted twice to close the window. This can be prevented by a slight change:

<script type="text/javascript">
  var isClosed = false;
  window.print();
  window.onfocus = function() {
    if(isClosed) { // Work around IE11 calling window.close twice
      return;
    }
    window.close();
    isClosed = true;
  }
</script>

Scala

s.stripPrefix("\"").stripSuffix("\"")

This works regardless of whether the string has or does not have quotes at the start and / or end.

Edit: Sorry, Scala only

Not sure about your question - "sideways" is the same as "landscape".

If you mean how to switch during runtime:

• Switch to previous layout orientation (for example, portrait, landscape): KEYPAD_7, Ctrl + F11
• Switch to next layout orientation (for example, portrait, landscape): KEYPAD_9, Ctrl + F12

From docs.

Since you want to check whether textboxes contains any value or not your code should do the job. You should be more specific about the error you are having. You can also do:

if(textBox1.Text == string.Empty || textBox2.Text == string.Empty)
   {
    MessageBox.Show("You must enter a value into both boxes");
   }

EDIT 2: based on @JonSkeet comments:

Usage of string.Compare is not required as per OP's original unedited post. String.Equals should do the job if one wants to compare strings, and StringComparison may be used to ignore case for the comparison. string.Compare should be used for order comparison. Originally the question contain this comparison,

string testString = "This is a test";
string testString2 = "This is not a test";

if (testString == testString2)
{
    //do some stuff;
}

the if statement can be replaced with

if(testString.Equals(testString2))

or following to ignore case.

if(testString.Equals(testString2,StringComparison.InvariantCultureIgnoreCase)) 

A couple of notes first: when you use Data/data1.txt as an argument, should it really be /Data/data1.txt (with a leading slash)? Also, should the outer loop scan only for .txt files, or all files in /Data? Here's an answer, assuming /Data/data1.txt and .txt files only:

#!/bin/bash
for filename in /Data/*.txt; do
    for ((i=0; i<=3; i++)); do
        ./MyProgram.exe "$filename" "Logs/$(basename "$filename" .txt)_Log$i.txt"
    done
done

Notes:

• /Data/*.txt expands to the paths of the text files in /Data (including the /Data/ part)
• $( ... ) runs a shell command and inserts its output at that point in the command line
• basename somepath .txt outputs the base part of somepath, with .txt removed from the end (e.g. /Data/file.txt -> file)

If you needed to run MyProgram with Data/file.txt instead of /Data/file.txt, use "${filename#/}" to remove the leading slash. On the other hand, if it's really Data not /Data you want to scan, just use for filename in Data/*.txt.

The statement you're executing is valid. The error seems to mean that Toad is including the trailing semicolon as part of the command, which does cause an ORA-00911 when it's included as part of a statement - since it is a statement separator in the client, not part of the statement itself.

It may be the following commented-out line that is confusing Toad (as described here); or it might be because you're trying to run everything as a single statement, in which case you can try to use the run script command (F9) instead of run statement (F5).

Just removing the commented-out line makes the problem go away, but if you also saw this with an actual commit then it's likely to be that you're using the wrong method to run the statements.

There is a bit more information about how Toad parses the semicolons in a comment on this related question, but I'm not familiar enough with Toad to go into more detail.

setattr(x, attr, 'magic')

For help on it:

>>> help(setattr)
Help on built-in function setattr in module __builtin__:

setattr(...)
    setattr(object, name, value)

    Set a named attribute on an object; setattr(x, 'y', v) is equivalent to
    ``x.y = v''.

Edit: However, you should note (as pointed out in a comment) that you can't do that to a "pure" instance of object. But it is likely you have a simple subclass of object where it will work fine. I would strongly urge the O.P. to never make instances of object like that.

Say if you have an application which has similar functionality as that of mine. Where your app is mostly offline and you want to render the Images one after the other. Then below is the approach that worked for me in React Native version 0.60.

1. First create a folder named Resources/Images and place all your images there.
2. Now create a file named Index.js (at Resources/Images) which is responsible for Indexing all the images in the Reources/Images folder.

const Images = { 'image1': require('./1.png'), 'image2': require('./2.png'), 'image3': require('./3.png') }

3. Now create a Component named ImageView at your choice of folder. One can create functional, class or constant component. I have used Const component. This file is responsible for returning the Image depending on the Index.

import React from 'react';
import { Image, Dimensions } from 'react-native';
import Images from './Index';
const ImageView = ({ index }) => {
    return (
        <Image
            source={Images['image' + index]}
        />
    )
}
export default ImageView;

4. Now from the component wherever you want to render the Static Images dynamically, just use the ImageView component and pass the index.

   < ImageView index={this.qno + 1} />

Note that once you have imported the google-play-services_lib project into your IDE, you will also need to add google-play-services.jar to: Project=>Properties=>Java build path=>Libraries=>Add JARs

This answer is wrriten in Kotlin, but can easily be translated to Java.

If your arraylist's size is within a fixed small range, then this is a great solution.

var duplicateDetected = false
    if(arrList.size > 1){
        for(i in 0 until arrList.size){
            for(j in 0 until arrList.size){
                if(i != j && arrList.get(i) == arrList.get(j)){
                    duplicateDetected = true
                }
            }
        }
    }

Here's a solution in pure PIL.

def blend_value(under, over, a):
    return (over*a + under*(255-a)) / 255

def blend_rgba(under, over):
    return tuple([blend_value(under[i], over[i], over[3]) for i in (0,1,2)] + [255])

white = (255, 255, 255, 255)

im = Image.open(object.logo.path)
p = im.load()
for y in range(im.size[1]):
    for x in range(im.size[0]):
        p[x,y] = blend_rgba(white, p[x,y])
im.save('/tmp/output.png')

For people searching the equivalent in SwiftUI for Textfield this is accentColor:

TextField("Label", text: $self.textToBind).accentColor(Color.red)

To check for an empty QueryString you should use Request.QueryString.HasKeys property.

To check if the key is present: Request.QueryString.AllKeys.Contains()

Then you can get ist's Value and do any other check you want, such as isNullOrEmpty, etc.

More esoteric ways:

Rails.cache.delete_matched("*")

For Redis:

Redis.new.keys.each{ |key| Rails.cache.delete(key) }

Seems you are looking for ORDER BY in DESCending order with LIMIT clause:

SELECT
 *
FROM
  scores
ORDER BY score DESC
LIMIT 10

Of course SELECT * could seriously affect performance, so use it with caution.

The If else statement needs to be wrapped in a .get or a .post to redirect. Such as

app.post('/login', function(req, res) {
});

or

app.get('/login', function(req, res) {
});

So I spent about 5 hours trying to figure out how to deal with this issue when trying to run

./manage.py makemigrations

With Ubuntu Server LTS 16.1, a full LAMP stack, Apache2 MySql 5.7 PHP 7 Python 3 and Django 1.10.2 I really struggled to find a good answer to this. In fact, I am still not satisfied, but the ONLY solution that worked for me is this...

sudo apt-get install build-essential python-dev libapache2-mod-wsgi-py3 libmysqlclient-dev

followed by (from inside the virtual environment)

pip install mysqlclient

I really dislike having to use dev installs when I am trying to set up a new web server, but unfortunately this configuration was the only mostly comfortable path I could take.

Another solution would be to write a wrapper that store the array like this:

localStorage.setItem('names_length', names.length);
localStorage.setItem('names_0', names[0]);
localStorage.setItem('names_1', names[1]);
localStorage.setItem('names_' + n, names[n]);

Removes the overhead of converting to JSON, but would be annoying if you need to remove elements, as you would have to re-index the array :)

You can use Padding widget in between those two widget or wrap those widgets with Padding widget.

Update

SizedBox widget can be use in between two widget to add space between two widget and it makes code more readable than padding widget.

Ex:

Column(
  children: <Widget>[
    Widget1(),
    SizedBox(height: 10),
    Widget2(),
  ],
),

Try this to read a file:

BufferedReader reader = null;

try {
    File file = new File("sample-file.dat");
    reader = new BufferedReader(new FileReader(file));

    String line;
    while ((line = reader.readLine()) != null) {
        System.out.println(line);
    }

} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        reader.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

How can I tell if I have uncommitted work in an Oracle transaction?

(a–b)/c*(d + e – f / g)

remember scanning the expression from leftmost to right most start on parenthesized terms follow the WHICH COMES FIRST rule... *, /, % are on the same level and higher than + and -.... so (a-b) = -bc prefix (a-b) = bc- for postfix another parenthesized term: (d + e - f / g) = do move the / first then plus '+' comes first before minus sigh '-' (remember they are on the same level..) (d + e - f / g) move / first (d + e - (/fg)) = prefix (d + e - (fg/)) = postfix followed by + then - ((+de) - (/fg)) = prefix ((de+) - (fg/)) = postfix

(-(+de)(/fg)) = prefix so the new expression is now -+de/fg (1) ((de+)(fg/)-) = postfix so the new expression is now de+fg/- (2)

(a–b)/c* hence

1. (a-b)/c*(d + e – f / g) = -bc prefix [-ab]/c*[-+de/fg] ---> taken from (1) / c * do not move yet so '/' comes first before '*' because they on the same level, move '/' to the rightmost : /[-ab]c * [-+de/fg] then move '*' to the rightmost

   • / [-ab]c[-+de/fg] = remove the grouping symbols = */-abc-+de/fg --> Prefix

2. (a-b)/c*(d + e – f / g) = bc- for postfix [ab-]/c*[de+fg/-]---> taken from (2) so '/' comes first before '' because they on the same level, move '/' to the leftmost: [ab-]c[de+fg/-]/ then move '' to the leftmost [ab-] c [de+fg/-]/ = remove the grouping symbols= a b - c d e + f g / - / * --> Postfix

Notice that there is a difference between

set encoding

and

set fileencoding

In the first case, you'll change the output encoding that is shown in the terminal. In the second case, you'll change the output encoding of the file that is written.

You can change the index as explained already using set_index. You don't need to manually swap rows with columns, there is a transpose (data.T) method in pandas that does it for you:

> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
                    ['ABERFELDIE', 534000, 600000]],
                    columns=['Locality', 2005, 2006])

> newdf = df.set_index('Locality').T
> newdf

Locality    ABBOTSFORD  ABERFELDIE
2005        427000      534000
2006        448000      600000

then you can fetch the dataframe column values and transform them to a list:

> newdf['ABBOTSFORD'].values.tolist()

[427000, 448000]

do like

<input name="name" id="name" type="text" value="Name" 
   onblur="fillField(this,'Name');" onfocus="clearField(this,'Name');"/>

and js

function fillField(input,val) {
      if(input.value == "")
         input.value=val;
};

function clearField(input,val) {
      if(input.value == val)
         input.value="";
};

If a value contains a comma, a newline character or a double quote, then the string must be enclosed in double quotes. E.g: "Newline char in this field \n".

another way to create a data url from blob url may be using canvas.

var canvas = document.createElement("canvas")
var context = canvas.getContext("2d")
context.drawImage(img, 0, 0) // i assume that img.src is your blob url
var dataurl = canvas.toDataURL("your prefer type", your prefer quality)

as what i saw in mdn, canvas.toDataURL is supported well by browsers. (except ie<9, always ie<9)

You can see a detailed description here.

Changelog

• 5.4.0 E_STRICT became part of E_ALL

• 5.3.0 E_DEPRECATED and E_USER_DEPRECATED introduced.

• 5.2.0 E_RECOVERABLE_ERROR introduced.

• 5.0.0 E_STRICT introduced (not part of E_ALL).

It makes a duplicate copy of the string passed in by running a malloc and strcpy of the string passed in. The malloc'ed buffer is returned to the caller, hence the need to run free on the return value.

Internet Explorer 9 and lower : You could use conditional comments to load an IE-specific stylesheet for any version (or combination of versions) that you wanted to specifically target.like below using external stylesheet.

<!--[if IE]>
  <link rel="stylesheet" type="text/css" href="all-ie-only.css" />
<![endif]-->

However, beginning in version 10, conditional comments are no longer supported in IE.

Internet Explorer 10 & 11 : Create a media query using -ms-high-contrast, in which you place your IE 10 and 11-specific CSS styles. Because -ms-high-contrast is Microsoft-specific (and only available in IE 10+), it will only be parsed in Internet Explorer 10 and greater.

@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
     /* IE10+ CSS styles go here */
}

Microsoft Edge 12 : Can use the @supports rule Here is a link with all the info about this rule

@supports (-ms-accelerator:true) {
  /* IE Edge 12+ CSS styles go here */ 
}

Inline rule IE8 detection

I have 1 more option but it is only detect IE8 and below version.

  /* For IE css hack */
  margin-top: 10px\9 /* apply to all ie from 8 and below */
  *margin-top:10px;  /* apply to ie 7 and below */
  _margin-top:10px; /* apply to ie 6 and below */

As you specefied for embeded stylesheet. I think you need to use media query and condition comment for below version.

A Node-based class of connected nodes is a standard approach. These can be hard to visualize.

Motivated from an essay on Python Patterns - Implementing Graphs, consider a simple dictionary:

Given

A binary tree

               a
              / \
             b   c
            / \   \
           d   e   f

Code

Make a dictionary of unique nodes:

tree = {
   "a": ["b", "c"],
   "b": ["d", "e"],
   "c": [None, "f"],
   "d": [None, None],
   "e": [None, None],
   "f": [None, None],
}

Details

• Each key-value pair is a unique node pointing to its children.
• A list (or tuple) holds an ordered pair of left/right children.
• With a dict having ordered insertion, assume the first entry is the root.
• Common methods can be functions that mutate or traverse the dict (see find_all_paths()).

Tree-based functions often include the following common operations:

• traverse: yield each node in a given order (usually left-to-right)
  • breadth-first search (BFS): traverse levels
  • depth-first search (DFS): traverse branches first (pre-/in-/post-order)
• insert: add a node to the tree depending on the number of children
• remove: remove a node depending on the number of children
• update: merge missing nodes from one tree to the other
• visit: yield the value of a traversed node

Try implementing all of these operations. Here we demonstrate one of these functions - a BFS traversal:

Example

import collections as ct


def traverse(tree):
    """Yield nodes from a tree via BFS."""
    q = ct.deque()                                         # 1
    root = next(iter(tree))                                # 2
    q.append(root)

    while q:
        node = q.popleft()
        children = filter(None, tree.get(node))
        for n in children:                                 # 3 
            q.append(n)
        yield node

list(traverse(tree))
# ['a', 'b', 'c', 'd', 'e', 'f']

This is a breadth-first search (level-order) algorithm applied to a dict of nodes and children.

1. Initialize a FIFO queue. We use a deque, but a queue or a list works (the latter is inefficient).
2. Get and enqueue the root node (assumes the root is the first entry in the dict, Python 3.6+).
3. Iteratively dequeue a node, enqueue its children and yield the node value.

See also this in-depth tutorial on trees.

Insight

Something great about traversals in general, we can easily alter the latter iterative approach to depth-first search (DFS) by simply replacing the queue with a stack (a.k.a LIFO Queue). This simply means we dequeue from the same side that we enqueue. DFS allows us to search each branch.

How? Since we are using a deque, we can emulate a stack by changing node = q.popleft() to node = q.pop() (right). The result is a right-favored, pre-ordered DFS: ['a', 'c', 'f', 'b', 'e', 'd'].

You can create a custom class to modify the content type and add the file to the response.

dist = sqrt( (x2 - x1)**2 + (y2 - y1)**2 )

As others have pointed out, you can also use the equivalent built-in math.hypot():

dist = math.hypot(x2 - x1, y2 - y1)

You can save the whole jstl object as a Javascript object by converting the whole object to json. It is possible by Jackson in java.

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonUtil{
   public static String toJsonString(Object obj){
      ObjectMapper objectMapper = ...; // jackson object mapper
      return objectMapper.writeValueAsString(obj);

I will answer with a horrible-looking, hand-drawn comic. The second image is the reason why result is undefined in your code example.

There are three basic types of join:

• INNER join compares two tables and only returns results where a match exists. Records from the 1st table are duplicated when they match multiple results in the 2nd. INNER joins tend to make result sets smaller, but because records can be duplicated this isn't guaranteed.
• CROSS join compares two tables and return every possible combination of rows from both tables. You can get a lot of results from this kind of join that might not even be meaningful, so use with caution.
• OUTER join compares two tables and returns data when a match is available or NULL values otherwise. Like with INNER join, this will duplicate rows in the one table when it matches multiple records in the other table. OUTER joins tend to make result sets larger, because they won't by themselves remove any records from the set. You must also qualify an OUTER join to determine when and where to add the NULL values:
  • LEFT means keep all records from the 1st table no matter what and insert NULL values when the 2nd table doesn't match.
  • RIGHT means the opposite: keep all records from the 2nd table no matter what and insert NULL values whent he 1st table doesn't match.
  • FULL means keep all records from both tables, and insert a NULL value in either table if there is no match.

Often you see will the OUTER keyword omitted from the syntax. Instead it will just be "LEFT JOIN", "RIGHT JOIN", or "FULL JOIN". This is done because INNER and CROSS joins have no meaning with respect to LEFT, RIGHT, or FULL, and so these are sufficient by themselves to unambiguously indicate an OUTER join.

Here is an example of when you might want to use each type:

• INNER: You want to return all records from the "Invoice" table, along with their corresponding "InvoiceLines". This assumes that every valid Invoice will have at least one line.
• OUTER: You want to return all "InvoiceLines" records for a particular Invoice, along with their corresponding "InventoryItem" records. This is a business that also sells service, such that not all InvoiceLines will have an IventoryItem.
• CROSS: You have a digits table with 10 rows, each holding values '0' through '9'. You want to create a date range table to join against, so that you end up with one record for each day within the range. By CROSS-joining this table with itself repeatedly you can create as many consecutive integers as you need (given you start at 10 to 1st power, each join adds 1 to the exponent). Then use the DATEADD() function to add those values to your base date for the range.

this will work definately !!!

  $v = Validator::make($request->all(),[
  'name' => ['Required','alpha']
  ]);

   if($v->passes()){
     print_r($request->name);
   }
   else{
     //this will return the errors & to check put "dd($errors);" in your blade(view)
     return back()->withErrors($v)->withInput();
   }

Take a look at this forum http://htmlcoderhelper.com/why-is-using-a-wild-card-with-a-java-import-statement-bad/. Theres a discussion on how using wildcards can lead to conflicts if you add new classes to the packages and if there are two classes with the same name in different packages where only one of them will be imported.

Update

List<Integer> i = new ArrayList<Integer>(Arrays.asList(0,1,2,3,4,5,6,7,8,9,10));
List<Integer> j = new ArrayList<Integer>();

You need to specify the type for array list or the compiler will give that warning because it cannot identify that you are using the list in a type safe way.

Use one way flow syntax property binding:

<div [innerHTML]="comment"></div>

From angular docs: "Angular recognizes the value as unsafe and automatically sanitizes it, which removes the <script> tag but keeps safe content such as the <b> element."

You can do something like this:

jQuery.fn.existsWithValue = function() { 
    return this.length && this.val().length; 
}

if ($(selector).existsWithValue()) {
        // Do something
}

The answer is in the meaning of each one, so in the results.

Note :
In SQLite there is no RIGHT OUTER JOIN or FULL OUTER JOIN.
And also in MySQL there is no FULL OUTER JOIN.

My answer is based on above Note.

When you have two tables like these:

--[table1]               --[table2]
id | name                id | name
---+-------              ---+-------
1  | a1                  1  | a2
2  | b1                  3  | b2

CROSS JOIN / OUTER JOIN :
You can have all of those tables data with CROSS JOIN or just with , like this:

SELECT * FROM table1, table2
--[OR]
SELECT * FROM table1 CROSS JOIN table2

--[Results:]
id | name | id | name 
---+------+----+------
1  | a1   | 1  | a2
1  | a1   | 3  | b2
2  | b1   | 1  | a2
2  | b1   | 3  | b2

INNER JOIN :
When you want to add a filter to above results based on a relation like table1.id = table2.id you can use INNER JOIN:

SELECT * FROM table1, table2 WHERE table1.id = table2.id
--[OR]
SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.id

--[Results:]
id | name | id | name 
---+------+----+------
1  | a1   | 1  | a2

LEFT [OUTER] JOIN :
When you want to have all rows of one of tables in the above result -with same relation- you can use LEFT JOIN:
(For RIGHT JOIN just change place of tables)

SELECT * FROM table1, table2 WHERE table1.id = table2.id 
UNION ALL
SELECT *, Null, Null FROM table1 WHERE Not table1.id In (SELECT id FROM table2)
--[OR]
SELECT * FROM table1 LEFT JOIN table2 ON table1.id = table2.id

--[Results:]
id | name | id   | name 
---+------+------+------
1  | a1   | 1    | a2
2  | b1   | Null | Null

FULL OUTER JOIN :
When you also want to have all rows of the other table in your results you can use FULL OUTER JOIN:

SELECT * FROM table1, table2 WHERE table1.id = table2.id
UNION ALL
SELECT *, Null, Null FROM table1 WHERE Not table1.id In (SELECT id FROM table2)
UNION ALL
SELECT Null, Null, * FROM table2 WHERE Not table2.id In (SELECT id FROM table1)
--[OR] (recommended for SQLite)
SELECT * FROM table1 LEFT JOIN table2 ON table1.id = table2.id
UNION ALL
SELECT * FROM table2 LEFT JOIN table1 ON table2.id = table1.id
WHERE table1.id IS NULL
--[OR]
SELECT * FROM table1 FULL OUTER JOIN table2 On table1.id = table2.id

--[Results:]
id   | name | id   | name 
-----+------+------+------
1    | a1   | 1    | a2
2    | b1   | Null | Null
Null | Null | 3    | b2

Well, as your need you choose each one that covers your need ;).

len() 

it will count the element in the list, tuple and string and dictionary, eg.

>>> mylist = [1,2,3] #list
>>> len(mylist)
3
>>> word = 'hello' # string 
>>> len(word)
5
>>> vals = {'a':1,'b':2} #dictionary
>>> len(vals)
2
>>> tup = (4,5,6) # tuple 
>>> len(tup)
3

Just for fun, another approach would be to just leave the paging and horizontal scrolling set, add a method that changes the order of the array items to convert from 'top to bottom, left to right' to visually 'left to right, top to bottom' and fill the in-between cells with empty hidden cells to make the spacing right. In case of 7 items in a grid of 9, this would go like this:

[1][4][7]
[2][5][ ]
[3][6][ ]

should become

[1][2][3]
[4][5][6]
[7][ ][ ]

so 1=1, 2=4, 3=7 etc. and 6=empty. You can reorder them by calculating the total number of rows and columns, then calculate the row and column number for each cell, change the row for the column and vice versa and then you have the new indexes. When the cell doesn't have a value corresponding to the image you can return an empty cell and set cell.hidden = YES; to it.

It works quite well in a soundboard app I built, so if anyone would like working code I'll add it. Only little code is required to make this trick work, it sounds harder than it is!

Update

I doubt this is the best solution, but by request here's working code:

- (void)viewDidLoad {
    // Fill an `NSArray` with items in normal order
    items = [NSMutableArray arrayWithObjects:
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 1", @"label", @"Some value 1", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 2", @"label", @"Some value 2", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 3", @"label", @"Some value 3", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 4", @"label", @"Some value 4", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 5", @"label", @"Some value 5", @"value", nil],
              nil
              ];

    // Calculate number of rows and columns based on width and height of the `UICollectionView` and individual cells (you might have to add margins to the equation based on your setup!)
    CGFloat w = myCollectionView.frame.size.width;
    CGFloat h = myCollectionView.frame.size.height;
    rows = floor(h / cellHeight);
    columns = floor(w / cellWidth);
}

// Calculate number of sections
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return ceil((float)items.count / (float)(rows * columns));
}

// Every section has to have every cell filled, as we need to add empty cells as well to correct the spacing
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return rows*columns;
}

// And now the most important one
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier@"myIdentifier" forIndexPath:indexPath];

    // Convert rows and columns
    int row = indexPath.row % rows;
    int col = floor(indexPath.row / rows);
    // Calculate the new index in the `NSArray`
    int newIndex = ((int)indexPath.section * rows * columns) + col + row * columns;

    // If the newIndex is within the range of the items array we show the cell, if not we hide it
    if(newIndex < items.count) {
        NSDictionary *item = [items objectAtIndex:newIndex];
        cell.label.text = [item objectForKey:@"label"];
        cell.hidden = NO;
    } else {
        cell.hidden = YES;
    }

    return cell;
}

If you'd like to use the didSelectItemAtIndexPath method you have to use the same conversion that is used in cellForItemAtIndexPath to get the corresponding item. If you have cell margins you need to add them to the rows and columns calculation, as those have to be correct in order for this to work.

void ExplodeString( const std::string& string, const char separator, std::list<int>& result ) {
    if( string.size() ) {
        std::string::const_iterator last = string.begin();
        for( std::string::const_iterator i=string.begin(); i!=string.end(); ++i ) {
            if( *i == separator ) {
                const std::string str(last,i);
                int id = atoi(str.c_str());
                result.push_back(id);
                last = i;
                ++ last;
            }
        }
        if( last != string.end() ) result.push_back( atoi(&*last) );
    }
}

If you are using the latest version of Android studio. then you don't need to install additional software for Git other than GIT itself - https://git-scm.com/downloads

Steps

1. Create an account on Github - https://github.com/join
2. Install Git
3. Open your working project in Android studio
4. GoTo - File -> Settings -> Version Controll -> GitHub
5. Enter Login and Password which you have created just on Git Account and click on test
6. Once all credentials are true - it shows Success message. o.w Invalid Cred.
7. Now click on VCS in android studio menu bar
8. Select Import into Version Control -> Share Project on GitHub
9. The popup dialog will occure contains all your files with check mark, do ok or commit all
10. At next time whenever you want to push your project just click on VCS - > Commit Changes -> Commmit and Push.

That's it. You can find your project on your github now

In case you're interested in bundling automatically your scripts separately from vendors ones:

var webpack = require('webpack'),
    pkg     = require('./package.json'),  //loads npm config file
    html    = require('html-webpack-plugin');

module.exports = {
  context : __dirname + '/app',
  entry   : {
    app     : __dirname + '/app/index.js',
    vendor  : Object.keys(pkg.dependencies) //get npm vendors deps from config
  },
  output  : {
    path      : __dirname + '/dist',
    filename  : 'app.min-[hash:6].js'
  },
  plugins: [
    //Finally add this line to bundle the vendor code separately
    new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.min-[hash:6].js'),
    new html({template : __dirname + '/app/index.html'})
  ]
};

You can read more about this feature in official documentation.

Java SE Runtime is for end user, so you need Java JRE version, the first version of Java was the 1, then 1.1 - 1.2 - 1.3 - 1.4 - 1.5 - 1.6 etc and usually each version is named by version so JRE 6 means Java jre 1.6, anyway there is the update version, for example 1.6 update 45, which is named java jre 6u45.

From what I know, they preferred to use the number 6 instead using 1.6 to better reflect the level of maturity, stability, scalability, security and more

Try adding a header() call before sending headers, like:

To extract number :

var arrNumber = new Array();
$('input[type=number]').each(function(){
    arrNumber.push($(this).val());
})

To extract text:

var arrText= new Array();
$('input[type=text]').each(function(){
    arrText.push($(this).val());
})

Edit : .map implementation

var arrText= $('input[type=text]').map(function(){
    return this.value;
}).get();

SPAN class code. Stylesheet:

<link rel="stylesheet" type="text/css" href="http://cdn.webrupee.com/font">

Now use the below mentioned code to type Indian Rupee symbol,

<span class="WebRupee">Rs.</span>

Once the popular font families will be updated to Unicode 6.0.0, then you will be able to type Indian Rupee Symbol by typing ₹ in HTML editor.

F function keys (F1,F2,F3,F4,F5 etc.) can be assigned to macros with the following codes :

Sub A_1()
    Call sndPlaySound32(ThisWorkbook.Path & "\a1.wav", 0)
End Sub

Sub B_1()
    Call sndPlaySound32(ThisWorkbook.Path & "\b1.wav", 0)
End Sub

Sub C_1()
    Call sndPlaySound32(ThisWorkbook.Path & "\c1.wav", 0)
End Sub

Sub D_1()
    Call sndPlaySound32(ThisWorkbook.Path & "\d1.wav", 0)
End Sub

Sub E_1()
    Call sndPlaySound32(ThisWorkbook.Path & "\e1.wav", 0)
End Sub


Sub auto_open()
    Application.OnKey "{F1}", "A_1"
    Application.OnKey "{F2}", "B_1"
    Application.OnKey "{F3}", "C_1"
    Application.OnKey "{F4}", "D_1"
    Application.OnKey "{F5}", "E_1"

Run: python -c "import ssl; print(ssl.get_default_verify_paths())" to check the current paths which are used to verify the certificate. Add your company's root certificate to one of those.

The path openssl_capath_env points to the environment variable: SSL_CERT_DIR.

If SSL_CERT_DIR doesn't exist, you will need to create it and point it to a valid folder within your filesystem. You can then add your certificate to this folder to use it.

Every time you add a new element to the List you need to re-bind your Grid. Something like:

List<Person> persons = new List<Person>();
persons.Add(new Person() { Name = "Joe", Surname = "Black" });
persons.Add(new Person() { Name = "Misha", Surname = "Kozlov" });
dataGridView1.DataSource = persons;

// added a new item
persons.Add(new Person() { Name = "John", Surname = "Doe" });
// bind to the updated source
dataGridView1.DataSource = persons;

The more efficient way I found in dealing with millions of folders and files is to capture directory listing through DOS command in some file and parse it. Once you have parsed data then you can do analysis and compute statistics.

Try regular expressions. You can find a certain pattern in your text and replace it with something that you want. I can't give you the exact code right now but you can test out your expressions using this.

As long as volumes are associated with a container(either running or not), they cannot be removed.

You have to run

docker inspect <container-id>/<container-name>

on each of the running/non-running containers where this volume might have been mounted onto.

If the volume is mounted onto any one of the containers, you should see it in the Mounts section of the inspect command output. Something like this :-

"Mounts": [
            {
                "Type": "volume",
                "Name": "user1",
                "Source": "/var/lib/docker/volumes/user1/_data",
                "Destination": "/opt",
                "Driver": "local",
                "Mode": "",
                "RW": true,
                "Propagation": ""
            }
        ],

After figuring out the responsible container(s), use :-

docker rm -f container-1 container-2 ...container-n in case of running containers

docker rm container-1 container-2 ...container-n in case of non-running containers

to completely remove the containers from the host machine.

Then try removing the volume using the command :-

docker volume remove <volume-name/volume-id>

For SQL Server 2008+ You can use CONVERT and FORMAT together.

**/** is used to get all files recursively including directory.

if os.path.isfile(filename) is used to check if filename variable is file or directory, if it is file then we can read that file. Here I am printing file.

If you're using C++11, you can use std::normal_distribution:

#include <random>

std::default_random_engine generator;
std::normal_distribution<double> distribution(/*mean=*/0.0, /*stddev=*/1.0);

double randomNumber = distribution(generator);

There are many other distributions you can use to transform the output of the random number engine.

Use position: relative on the parent element.

Also note that had you not added any position attributes to any of the divs you wouldn't have seen this behavior. Juan explains further.

jQuery.Deferred() can simplify management of asynchronous sequencing and error handling.

polling_active = true // set false to interrupt polling

function initiate_polling()
    {
    $.Deferred().resolve() // optional boilerplate providing the initial 'then()'
    .then( () => $.Deferred( d=>setTimeout(()=>d.resolve(),5000) ) ) // sleep
    .then( () => $.get('/my-api') ) // initiate AJAX
    .then( response =>
        {
        if ( JSON.parse(response).my_result == my_target ) polling_active = false
        if ( ...unhappy... ) return $.Deferred().reject("unhappy") // abort
        if ( polling_active ) initiate_polling() // iterative recursion
        })
    .fail( r => { polling_active=false, alert('failed: '+r) } ) // report errors
    }

This is an elegant approach, but there are some gotchas...

• If you don't want a then() to fall through immediately, the callback should return another thenable object (probably another Deferred), which the sleep and ajax lines both do.
• The others are too embarrassing to admit. :)

Here for usefulness... some code for getting the values into a list, which converts the enum into readable form for the text

public class KeyValuePair

You need to Add C:\Program Files\nodejs to your PATH environment variable. To do this follow these steps:

1. Use the global Search Charm to search "Environment Variables"
2. Click "Edit system environment variables"
3. Click "Environment Variables" in the dialog.
4. In the "System Variables" box, search for Path and edit it to include C:\Program Files\nodejs. Make sure it is separated from any other paths by a ;.

You will have to restart any currently-opened command prompts before it will take effect.

1. Create a Cocoa Touch class.

Use this to get an array with the local users and the groups they are member of:

Get-LocalUser | 
    ForEach-Object { 
        $user = $_
        return [PSCustomObject]@{ 
            "User"   = $user.Name
            "Groups" = Get-LocalGroup | Where-Object {  $user.SID -in ($_ | Get-LocalGroupMember | Select-Object -ExpandProperty "SID") } | Select-Object -ExpandProperty "Name"
        } 
    }

To get an array with the local groups and their members:

Get-LocalGroup | 
    ForEach-Object {
        $group = $_
        return [PSCustomObject]@{ 
            "Group"   = $group.Name
            "Members" = $group | Get-LocalGroupMember | Select-Object -ExpandProperty "Name"
        } 
    } 

Look at the keys and indentation in your print_r:

echo $myarray[0]['email'];

echo $myarray[0]['gender'];

...etc

You have to loop through every cell in the range "D3:D6" and construct your To string. Simply assigning it to a variant will not solve the purpose. EmailTo becomes an array if you assign the range directly to it. You can do this as well but then you will have to loop through the array to create your To string

The frames you're sending need to be formatted according to the WebSocket framing format. For sending messages, this format is as follows:

• one byte which contains the type of data (and some additional info which is out of scope for a trivial server)
• one byte which contains the length
• either two or eight bytes if the length does not fit in the second byte (the second byte is then a code saying how many bytes are used for the length)
• the actual (raw) data

The first byte will be 1000 0001 (or 129) for a text frame.

The second byte has its first bit set to 0 because we're not encoding the data (encoding from server to client is not mandatory).

It is necessary to determine the length of the raw data so as to send the length bytes correctly:

• if 0 <= length <= 125, you don't need additional bytes
• if 126 <= length <= 65535, you need two additional bytes and the second byte is 126
• if length >= 65536, you need eight additional bytes, and the second byte is 127

The length has to be sliced into separate bytes, which means you'll need to bit-shift to the right (with an amount of eight bits), and then only retain the last eight bits by doing AND 1111 1111 (which is 255).

After the length byte(s) comes the raw data.

This leads to the following pseudocode:

bytesFormatted[0] = 129

indexStartRawData = -1 // it doesn't matter what value is
                       // set here - it will be set now:

if bytesRaw.length <= 125
    bytesFormatted[1] = bytesRaw.length

    indexStartRawData = 2

else if bytesRaw.length >= 126 and bytesRaw.length <= 65535
    bytesFormatted[1] = 126
    bytesFormatted[2] = ( bytesRaw.length >> 8 ) AND 255
    bytesFormatted[3] = ( bytesRaw.length      ) AND 255

    indexStartRawData = 4

else
    bytesFormatted[1] = 127
    bytesFormatted[2] = ( bytesRaw.length >> 56 ) AND 255
    bytesFormatted[3] = ( bytesRaw.length >> 48 ) AND 255
    bytesFormatted[4] = ( bytesRaw.length >> 40 ) AND 255
    bytesFormatted[5] = ( bytesRaw.length >> 32 ) AND 255
    bytesFormatted[6] = ( bytesRaw.length >> 24 ) AND 255
    bytesFormatted[7] = ( bytesRaw.length >> 16 ) AND 255
    bytesFormatted[8] = ( bytesRaw.length >>  8 ) AND 255
    bytesFormatted[9] = ( bytesRaw.length       ) AND 255

    indexStartRawData = 10

// put raw data at the correct index
bytesFormatted.put(bytesRaw, indexStartRawData)


// now send bytesFormatted (e.g. write it to the socket stream)

Receiving messages

(In other words, browser → server)

The frames you obtain are in the following format:

• one byte which contains the type of data
• one byte which contains the length
• either two or eight additional bytes if the length did not fit in the second byte
• four bytes which are the masks (= decoding keys)
• the actual data

The first byte usually does not matter - if you're just sending text you are only using the text type. It will be 1000 0001 (or 129) in that case.

The second byte and the additional two or eight bytes need some parsing, because you need to know how many bytes are used for the length (you need to know where the real data starts). The length itself is usually not necessary since you have the data already.

The first bit of the second byte is always 1 which means the data is masked (= encoded). Messages from the client to the server are always masked. You need to remove that first bit by doing secondByte AND 0111 1111. There are two cases in which the resulting byte does not represent the length because it did not fit in the second byte:

• a second byte of 0111 1110, or 126, means the following two bytes are used for the length
• a second byte of 0111 1111, or 127, means the following eight bytes are used for the length

The four mask bytes are used for decoding the actual data that has been sent. The algorithm for decoding is as follows:

decodedByte = encodedByte XOR masks[encodedByteIndex MOD 4]

where encodedByte is the original byte in the data, encodedByteIndex is the index (offset) of the byte counting from the first byte of the real data, which has index 0. masks is an array containing of the four mask bytes.

This leads to the following pseudocode for decoding:

secondByte = bytes[1]

length = secondByte AND 127 // may not be the actual length in the two special cases

indexFirstMask = 2          // if not a special case

if length == 126            // if a special case, change indexFirstMask
    indexFirstMask = 4

else if length == 127       // ditto
    indexFirstMask = 10

masks = bytes.slice(indexFirstMask, 4) // four bytes starting from indexFirstMask

indexFirstDataByte = indexFirstMask + 4 // four bytes further

decoded = new array

decoded.length = bytes.length - indexFirstDataByte // length of real data

for i = indexFirstDataByte, j = 0; i < bytes.length; i++, j++
    decoded[j] = bytes[i] XOR masks[j MOD 4]


// now use "decoded" to interpret the received data

The easiest way to tweak this in my opinion (imho) is to edit the .git/config file in your repository. Look for the entry you messed up and just tweak the URL.

On my machine in a repo I regularly use it looks like this:

KidA% cat .git/config 
[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    autocflg = true
[remote "origin"]
    url = ssh://localhost:8888/opt/local/var/git/project.git
    #url = ssh://xxx.xxx.xxx.xxx:80/opt/local/var/git/project.git
    fetch = +refs/heads/*:refs/remotes/origin/*

The line you see commented out is an alternative address for the repository that I sometimes switch to simply by changing which line is commented out.

This is the file that is getting manipulated under-the-hood when you run something like git remote rm or git remote add but in this case since its only a typo you made it might make sense to correct it this way.

A minimalist implementation of the \url macro that uses only Tex primitives:

\def\url#1{\expandafter\string\csname #1\endcsname}

This url absolutely won't break over lines, though; the hypperef package is better for that.

pip install opencv-python

or

pip install opencv-python3 

will definately works fine

Just multiply the number by 100, round, and divide the resulting number by 100.

For simple stuff, System.currentTimeMillis() can work.

It's actually so common that my IDE is setup so that upon entering "t0" it generates me the following line:

final long t0 = System.currentTimeMillis()

But for more complicated things, you'll probably want to use statistical time measurements, like here (scroll down a bit and look at the time measurements expressed including standard deviations etc.):

http://perf4j.codehaus.org/devguide.html

There is another approach. It uses List.FindIndex and List.RemoveAt.

While I would probably use the solution presented by KeithS (just the simple Where/ToList) this approach differs in that it mutates the original list object. This can be a good (or a bad) "feature" depending upon expectations.

In any case, the FindIndex (coupled with a guard) ensures the RemoveAt will be correct if there are gaps in the IDs or the ordering is wrong, etc, and using RemoveAt (vs Remove) avoids a second O(n) search through the list.

Here is a LINQPad snippet:

var list = new List<int> { 1, 3, 2 };
var index = list.FindIndex(i => i == 2); // like Where/Single
if (index >= 0) {   // ensure item found
    list.RemoveAt(index);
}
list.Dump();        // results -> 1, 3

Happy coding.

I used FragmentActivity

TabAdapter = new TabPagerAdapter(((FragmentActivity) getActivity()).getSupportFragmentManager());

We can convert ararylist to array using 3 mrthod

1. public Object[] toArray() - it will return array of object

   Object[] array = list.toArray();

2. public T[] toArray(T[] a) - In this way we will create array and toArray Take it as argument then return it

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

3. Public get() method;

   Iterate ararylist and one by one add element in array.

For more details for these method Visit Java Vogue

Also, you can try use CustomScrollView

CustomScrollView(
      controller: _scrollController,
      slivers: <Widget>[
        SliverList(
          delegate: SliverChildBuilderDelegate(
            (BuildContext context, int index) {
              final OrderModel order = _orders[index];

              return Container(
                margin: const EdgeInsets.symmetric(
                  vertical: 8,
                ),
                child: _buildOrderCard(order, size, context),
              );
            },
            childCount: _orders.length,
          ),
        ),
        SliverToBoxAdapter(
          child: _buildPreloader(context),
        ),
      ],
    );

Tip: _buildPreloader return CircularProgressIndicator or Text

In my case i want to show under ListView some widgets. Use Column does't work me, because widgets around ListView inside Column showing always "up" on the screen, like "position absolute"

Sorry for my bad english

You can use the below effect to animate, you can change the values as per your requirements

$("#myElem").fadeIn('slow').animate({opacity: 1.0}, 1500).effect("pulsate", { times: 2 }, 800).fadeOut('slow'); 

create shape.xml in drawable folder

like shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
  <stroke android:width="2dp"
    android:color="#FFFFFF"/>
  <gradient 
    android:angle="225"
    android:startColor="#DD2ECCFA"
    android:endColor="#DD000000"/>
<corners
    android:bottomLeftRadius="7dp"
    android:bottomRightRadius="7dp"
    android:topLeftRadius="7dp"
   android:topRightRadius="7dp" />
</shape>

and in myactivity.xml

you can use

<Button
    android:id="@+id/btn_Shap"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text="@string/Shape"
    android:background="@drawable/shape"/>

You need to place google-services.json into app/ dir. And for each build type, there should be accordant director in app/src folder.

For example, if you have release and debug:

app/google-services.json
app/src/debug/google-services.json

In all google-services.json files you should specify correct package_name according to build type.

For example, inside debug dir it should be like {com.myapp}.debug

I did not have enough reputation to comment and hence am adding a new answer.
Gasek answer is quite correct. Just one thing: if you are updating the .bash_profile file or the /etc/profile, those changes would be reflected only after you do a new login. In case you want to set the env variable and then use it in subsequent tasks in the same playbook, consider adding those environment variables in the .bashrc file.
I guess the reason behind this is the login and the non-login shells.
Ansible, while executing different tasks, reads the parameters from a .bashrc file instead of the .bash_profile or the /etc/profile.

As an example, if I updated my path variable to include the custom binary in the .bash_profile file of the respective user and then did a source of the file. The next subsequent tasks won't recognize my command. However if you update in the .bashrc file, the command would work.

 - name: Adding the path in the bashrc files
   lineinfile: dest=/root/.bashrc line='export PATH=$PATH:path-to-mysql/bin' insertafter='EOF' regexp='export PATH=\$PATH:path-to-mysql/bin' state=present
 
-  - name: Source the bashrc file
   shell: source /root/.bashrc

 - name: Start the mysql client
   shell: mysql -e "show databases";

This would work, but had I done it using profile files the mysql -e "show databases" would have given an error.

- name: Adding the path in the Profile files
   lineinfile: dest=/root/.bash_profile line='export PATH=$PATH:{{install_path}}/{{mysql_folder_name}}/bin' insertafter='EOF' regexp='export PATH=\$PATH:{{install_path}}/{{mysql_folder_name}}/bin' state=present

 - name: Source the bash_profile file
   shell: source /root/.bash_profile

 - name: Start the mysql client
   shell: mysql -e "show databases";

This one won't work, if we have all these tasks in the same playbook.

You need to return your promise to the calling function.

islogged:function(){
    var cUid=sessionService.get('uid');
    alert("in loginServce, cuid is "+cUid);
    var $checkSessionServer=$http.post('data/check_session.php?cUid='+cUid);
    $checkSessionServer.then(function(){
        alert("session check returned!");
        console.log("checkSessionServer is "+$checkSessionServer);
    });
    return $checkSessionServer; // <-- return your promise to the calling function
}

You don't need floats. In fact, they're useless because floats are ignored in flexbox.

You also don't need CSS positioning.

There are several flex methods available. auto margins have been mentioned in another answer.

Here are two other options:

• Use justify-content: space-between and the order property.
• Use justify-content: space-between and reverse the order of the divs.

.parent {_x000D_
    display: flex;_x000D_
    justify-content: space-between;_x000D_
}_x000D_
_x000D_
.parent:first-of-type > div:last-child { order: -1; }_x000D_
_x000D_
p { background-color: #ddd;}

<p>Method 1: Use <code>justify-content: space-between</code> and <code>order-1</code></p>_x000D_
_x000D_
<div class="parent">_x000D_
    <div class="child" style="float:right"> Ignore parent? </div>_x000D_
    <div>another child </div>_x000D_
</div>_x000D_
_x000D_
<hr>_x000D_
_x000D_
<p>Method 2: Use <code>justify-content: space-between</code> and reverse the order of _x000D_
             divs in the mark-up</p>_x000D_
_x000D_
<div class="parent">_x000D_
    <div>another child </div>_x000D_
    <div class="child" style="float:right"> Ignore parent? </div>_x000D_
</div>

Faster way of writing it would be...

in = open('path/to/input/file').read()
out = open('path/to/input/file', 'w')
replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}
for i in replacements.keys():
    in = in.replace(i, replacements[i])
out.write(in)
out.close

This eliminated a lot of the iterations that the other answers suggest, and will speed up the process for longer files.

Just wanted to add that you can do this to apply dos2unix fix for all files under a directory, as it saved me heaps of time when we had to 'fix' a bunch of our scripts.

find . -type f -exec dos2unix.exe {} \;

I'd do it as a comment to Roman's answer, but I don't have access to commenting yet.

On Windows

import winsound
duration = 1000  # milliseconds
freq = 440  # Hz
winsound.Beep(freq, duration)

Where freq is the frequency in Hz and the duration is in milliseconds.

On Linux and Mac

import os
duration = 1  # seconds
freq = 440  # Hz
os.system('play -nq -t alsa synth {} sine {}'.format(duration, freq))

In order to use this example, you must install sox.

On Debian / Ubuntu / Linux Mint, run this in your terminal:

sudo apt install sox

On Mac, run this in your terminal (using macports):

sudo port install sox

Speech on Mac

import os
os.system('say "your program has finished"')

Speech on Linux

import os
os.system('spd-say "your program has finished"')

You need to install the speech-dispatcher package in Ubuntu (or the corresponding package on other distributions):

sudo apt install speech-dispatcher

I'm taking some guesses here, because I don't quite understand what you're asking.

I think that what you want is a count of the number of lines on which the pattern 'echo' appears in the given file.

I've pasted your sample text into a file called 6741967.

First, grep finds the matches:

james@Brindle:tmp$grep echo 6741967 
    echo "Preparing to add a new user..."
echo "1. Add user"
echo "2. Exit"
echo "Enter your choice: "

Second, use wc -l to count the lines

james@Brindle:tmp$grep echo 6741967  | wc -l
       4

To the very first please run the below commands to install python dependencies otherwise python runserver command will throw error.

sudo apt-get install libmysqlclient-dev
sudo pip install MySQL-python

Then configure the settings.py file as defined by #Andy and at the last execute :

python manage.py runserver

The controller function/object represents an abstraction model-view-controller (MVC). While there is nothing new to write about MVC, it is still the most significant advanatage of angular: split the concerns into smaller pieces. And that's it, nothing more, so if you need to react on Model changes coming from View the Controller is the right person to do that job.

The story about link function is different, it is coming from different perspective then MVC. And is really essential, once we want to cross the boundaries of a controller/model/view (template).

Let' start with the parameters which are passed into the link function:

function link(scope, element, attrs) {

• scope is an Angular scope object.
• element is the jqLite-wrapped element that this directive matches.
• attrs is an object with the normalized attribute names and their corresponding values.

To put the link into the context, we should mention that all directives are going through this initialization process steps: Compile, Link. An Extract from Brad Green and Shyam Seshadri book Angular JS:

Compile phase (a sister of link, let's mention it here to get a clear picture):

In this phase, Angular walks the DOM to identify all the registered directives in the template. For each directive, it then transforms the DOM based on the directive’s rules (template, replace, transclude, and so on), and calls the compile function if it exists. The result is a compiled template function,

Link phase:

To make the view dynamic, Angular then runs a link function for each directive. The link functions typically creates listeners on the DOM or the model. These listeners keep the view and the model in sync at all times.

A nice example how to use the link could be found here: Creating Custom Directives. See the example: Creating a Directive that Manipulates the DOM, which inserts a "date-time" into page, refreshed every second.

Just a very short snippet from that rich source above, showing the real manipulation with DOM. There is hooked function to $timeout service, and also it is cleared in its destructor call to avoid memory leaks

.directive('myCurrentTime', function($timeout, dateFilter) {

 function link(scope, element, attrs) {

 ...

 // the not MVC job must be done
 function updateTime() {
   element.text(dateFilter(new Date(), format)); // here we are manipulating the DOM
 }

 function scheduleUpdate() {
   // save the timeoutId for canceling
   timeoutId = $timeout(function() {
     updateTime(); // update DOM
     scheduleUpdate(); // schedule the next update
   }, 1000);
 }

 element.on('$destroy', function() {
   $timeout.cancel(timeoutId);
 });

 ...

Aspect-oriented programming lets you trap assignments or fetches and attach intercepting logic to them, which I propose is the right way to solve the problem. (The issue of whether they should be public or protected or package-protected is orthogonal.)

Thus you start out with unintercepted fields with the right access qualifier. As your program requirements grow you attach logic to perhaps validate, make a copy of the object being returned, etc.

The getter/setter philosophy imposes costs on a large number of simple cases where they are not needed.

Whether aspect-style is cleaner or not is somewhat qualitative. I would find it easy to see just the variables in a class and view the logic separately. In fact, the raison d'etre for Apect-oriented programming is that many concerns are cross-cutting and compartmentalizing them in the class body itself is not ideal (logging being an example -- if you want to log all gets Java wants you to write a whole bunch of getters and keeping them in sync but AspectJ allows you a one-liner).

The issue of IDE is a red-herring. It is not so much the typing as it is the reading and visual pollution that arises from get/sets.

Annotations seem similar to aspect-oriented programming at first sight however they require you to exhaustively enumerate pointcuts by attaching annotations, as opposed to a concise wild-card-like pointcut specification in AspectJ.

I hope awareness of AspectJ prevents people from prematurely settling on dynamic languages.

I think TrungTN and anon's answer is okay, but MartinStettner's way of implementing the hex() function is not really simple, and too dark, considering hex << (int)mychar is already a workaround.

here is my solution to make "<<" operator easier:

#include <sstream>
#include <iomanip>

string uchar2hex(unsigned char inchar)
{
  ostringstream oss (ostringstream::out);
  oss << setw(2) << setfill('0') << hex << (int)(inchar);
  return oss.str();
}

int main()
{
  unsigned char a = 131;
  std::cout << uchar2hex(a) << std::endl;
}

It's just not worthy implementing a stream operator :-)

I'm in windows 10, using WAMP64 server. Searched for my.cnf and my.ini. Found my.ini in C:\wamp64\bin\mariadb\mariadb10.2.14.

Following the instructions from the colleagues:

1. Opened the quick start menu from Wampserver, selected 'Stop All Services'
2. Opened my.ini in a text editor, searched for [mysqld]
3. Added 'skip-grant-tables' at the end of the [mysqld] section (but within it)
4. Save the file, leave the editor open
5. In the Wampserver menu, select "Restart Services'. There will be a warning about the skip-grant-tables option
6. In the Wampserver menu select MySQL to open the prompt
7. It asked for a password, just press enter
8. Paste the command ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newpassword';
9. It must report that the operation was successful (no tables affected)
10. In the my.ini file, erase the 'skip-grant-tables' line, save the file
11. In the WampServer menu, select once more Restart Service

Now you can enter with the new password. Thanks to all answers here.

Things that can cause a delete to be slow:

• deleting a lot of records
• many indexes
• missing indexes on foreign keys in child tables. (thank you to @CesarAlvaradoDiaz for mentioning this in the comments)
• deadlocks and blocking
• triggers
• cascade delete (those ten parent records you are deleting could mean millions of child records getting deleted)
• Transaction log needing to grow
• Many Foreign keys to check

So your choices are to find out what is blocking and fix it or run the deletes in off hours when they won't be interfering with the normal production load. You can run the delete in batches (useful if you have triggers, cascade delete, or a large number of records). You can drop and recreate the indexes (best if you can do that in off hours too).

Just a a bit modifications on reading string from a file method for more performance

private String readFromFile(Context context, String fileName) {
    if (context == null) {
        return null;
    }

    String ret = "";

    try {
        InputStream inputStream = context.openFileInput(fileName);

        if ( inputStream != null ) {
            InputStreamReader inputStreamReader = new InputStreamReader(inputStream);               

            int size = inputStream.available();
            char[] buffer = new char[size];

            inputStreamReader.read(buffer);

            inputStream.close();
            ret = new String(buffer);
        }
    }catch (Exception e) {
        e.printStackTrace();
    }

    return ret;
}

On some kind of linux like ubuntu, first, do apt-get update and then try installing the python-pip package. without apt-get update, you might get error such as

E: Unable to locate package python-pip

1.Update :

sudo apt-get update

2.Install the pip package

For python2

sudo apt-get install python-pip

or

For python3

sudo apt-get install python3-pip

And done!

This solution worked for me:

NumberFormat.getNumberInstance(Locale.US).format(Integer.valueOf("String Your Number"));

Use " instead of " to escape it.

web.config is an XML file so you should use XML escaping.

connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"

See this forum thread.

Update:

" should work, but as it doesn't, have you tried some of the other string escape sequences for .NET? \" and ""?

Update 2:

Try single quotes for the connectionString:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Or:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Update 3:

From MSDN (SqlConnection.ConnectionString Property):

To include values that contain a semicolon, single-quote character, or double-quote character, the value must be enclosed in double quotation marks. If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotation marks.

So:

connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"

The issue is not with web.config, but the format of the connection string. In a connection string, if you have a " in a value (of the key-value pair), you need to enclose the value in '. So, while Password=somepass"word does not work, Password='somepass"word' does.

Are you tied to this library? Google Gson is very popular. I have myself not used it with Generics but their front page says Gson considers support for Generics very important.

You can use

Well, as the error says, you have an expression (((t[1])/length) * t[1]) on the left side of the assignment, rather than a variable name. You have that expression, and then you tell Python to add string to it (which is always "") and assign it to... where? ((t[1])/length) * t[1] isn't a variable name, so you can't store the result into it.

Did you mean string += ((t[1])/length) * t[1]? That would make more sense. Of course, you're still trying to add a number to a string, or multiply by a string... one of those t[1]s should probably be a t[0].

What do you mean by impacts? Content will flow around a float. That's how they work.

If you want it to appear above your design, try setting:

z-index: 10;  
position: absolute;  
right: 0;  
top: 0;

I think that what you have written is perfectly fine. I also don't see any readability issue with having multiple return statements.

I would always prefer to return from the point in the code when I know to return and this will avoid running logic below the return.

There can be an argument for having a single return point for debugging and logging. But, in your code, there is no issue of debugging and logging if we use it. It is very simple and readable the way you wrote.

It follows the convention that static methods should be thread-safe, but actually in v2 that static api is a proxy to an instance method on a default instance: in the case protobuf-net, it internally minimises contention points, and synchronises the internal state when necessary. Basically the library goes out of its way to do things right so that you can have simple code.

CSS:

.reverse {
  transform: rotate(180deg);
}

.rotate {
  animation-duration: .5s;
  animation-iteration-count: 1;
  animation-name: yoyo;
  animation-timing-function: linear;
}

@keyframes yoyo {
  from { transform: rotate(  0deg); }
  to   { transform: rotate(360deg); }
}

Javascript:

$(buttonElement).click(function () {
  $(".arrow").toggleClass("reverse")

  return false
})

$(buttonElement).hover(function () {
  $(".arrow").addClass("rotate")
}, function() {
  $(".arrow").removeClass("rotate")
})

PS: I've found this somewhere else but don't remember the source

use the limit clausule, with the offset to choose the row number -1 so if u wanna get the number 8 row so use:

limit 1 offset 7

There are several options... assuming you found your TD by var td = document.getElementyById('myTD_ID'); you can do:

• td.innerHTML = "mytext";

• td.textContent= "mytext";

• td.innerText= "mytext"; - this one may not work outside IE? Not sure

• Use firstChild or children array as previous poster noted.

If it's just the text that needs to be changed, textContent is faster and less prone to XSS attacks (https://developer.mozilla.org/en-US/docs/Web/API/Node.textContent)

There's pycron which I really as a Cron implementation for windows, but there's also the built in scheduler which should work just fine for what you need (Control Panel -> Scheduled Tasks -> Add Scheduled Task).

Here is an extension method that will convert an object to a ViewDataDictionary.

public static ViewDataDictionary ToViewDataDictionary(this object values)
{
    var dictionary = new ViewDataDictionary();
    foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(values))
    {
        dictionary.Add(property.Name, property.GetValue(values));
    }
    return dictionary;
}

You can then use it in your view like so:

@Html.Partial("_MyPartial", new
{
    Property1 = "Value1",
    Property2 = "Value2"
}.ToViewDataDictionary())

Which is much nicer than the new ViewDataDictionary { { "Property1", "Value1" } , { "Property2", "Value2" }} syntax.

Then in your partial view, you can use ViewBag to access the properties from a dynamic object rather than indexed properties, e.g.

<p>@ViewBag.Property1</p>
<p>@ViewBag.Property2</p>

As Dan pointed out, even once you normalize for clock frequency (which can be misleading in itself in pipelined designs), results will vary wildly based on CPU architecture (individual ALU/FPU performance, as well as actual number of ALUs/FPUs available per core in superscalar designs which influences how many independent operations can execute in parallel -- the latter factor is not exercised by the code below as all operations below are sequentially dependent.)

If start can't find what it's looking for, it does what you describe.

Since what you're doing should work, it's very likely you're leaving out some quotes (or putting extras in).

A beginner's mistake...i was using app.use(express.json()); in a local module instead of the main file (entry point).

As of May 2019, version 6.1.0 of the Firebase SDK for Cloud Storage now supports listing all objects from a bucket. You simply need to call listAll() in a Reference:

    // Since you mentioned your images are in a folder,
    // we'll create a Reference to that folder:
    var storageRef = firebase.storage().ref("your_folder");


    // Now we get the references of these images
    storageRef.listAll().then(function(result) {
      result.items.forEach(function(imageRef) {
        // And finally display them
        displayImage(imageRef);
      });
    }).catch(function(error) {
      // Handle any errors
    });

    function displayImage(imageRef) {
      imageRef.getDownloadURL().then(function(url) {
        // TODO: Display the image on the UI
      }).catch(function(error) {
        // Handle any errors
      });
    }

Please note that in order to use this function, you must opt-in to version 2 of Security Rules, which can be done by making rules_version = '2'; the first line of your security rules:

    rules_version = '2';
    service firebase.storage {
      match /b/{bucket}/o {
        match /{allPaths=**} {

I'd recommend checking the docs for further reference.

Also, according to setup, on Step 5, this script is not allowed for Node.js since require("firebase/app"); won't return firebase.storage() as a function. This is only achieved using import * as firebase from 'firebase/app';.

To redirect Without Query String add below lines in Server block under listen port line:

if ($uri ~ .*.containingString$) {
           return 301 https://$host/$uri/;
}

With Query String:

if ($uri ~ .*.containingString$) {
           return 301 https://$host/$uri/?$query_string;
}

Another way:

$c = 'A';
$chars = array($c);
while ($c < 'Z') $chars[] = ++$c;

using List Comprehension:

>>> L = [1]*5
>>> [x+1 for x in L]
[2, 2, 2, 2, 2]
>>> 

which roughly translates to using a for loop:

>>> newL = []
>>> for x in L:
...     newL+=[x+1]
... 
>>> newL
[2, 2, 2, 2, 2]

or using map:

>>> map(lambda x:x+1, L)
[2, 2, 2, 2, 2]
>>> 

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

If you need to interact directly with the DOM element, why not just use document.getElementById since, if you are trying to interact with a specific element you will probably know the id, as assuming that the classname is on only one element or some other option tends to be risky.

But, I tend to agree with the others, that in most cases you should learn to do what you need using what jQuery gives you, as it is very flexible.

UPDATE: Based on a comment: Here is a post with a nice explanation: http://www.mail-archive.com/[email protected]/msg04461.html

$(this).attr("checked") ? $(this).val() : 0

This will return the value if it's checked, or 0 if it's not.

$(this).val() is just reaching into the dom and getting the attribute "value" of the element, whether or not it's checked.

Put breakpoints - double click on the margin. Run > Debug > Yes (if dialog appears), then use commands from Run menu or shortcuts - F5, F6, F7, F8.

I was also having the same problem. I tried the following and it's working for me now:
Please try the following steps:

Go to..

File > Settings > Appearance & Behavior > System Settings > HTTP Proxy [Under IDE Settings] Enable following option Auto-detect proxy settings

On Mac it's under:

Android Studio > Preferences > Appearance & Behaviour... etc

you can also use the test connection button and check with google.com to see if it works or not.

You can also check the local changelog to verify whether or not OpenSSL is patched against the vulnerability with the following command:

rpm -q --changelog openssl | grep CVE-2014-0224

If a result is not returned, then you must patch OpenSSL.

No benefit of writing R.java yourself because it is changed on every build,

Just remember to use R.something for example : R.raw.filename from inside classes that has package value similar to the package value inside the AndroidManifest.xml

because R. resources IDs are defined for the current application or library and they are all checked if exist on compile time, so does not make sense to allow them to be accessed from "code" that does not target the current application or library and can be used in other places.

Here's another code example for a single paged view. Implementation for viewControllerAtIndex is omitted here, it should return the correct view controller for the given index.

- (void)changePage:(UIPageViewControllerNavigationDirection)direction {
    NSUInteger pageIndex = ((FooViewController *) [_pageViewController.viewControllers objectAtIndex:0]).pageIndex;

    if (direction == UIPageViewControllerNavigationDirectionForward) {
        pageIndex++;
    }
    else {
        pageIndex--;
    }

    FooViewController *viewController = [self viewControllerAtIndex:pageIndex];

    if (viewController == nil) {
        return;
    }

    [_pageViewController setViewControllers:@[viewController]
                                  direction:direction
                                   animated:YES
                                 completion:nil];
}

Pages can be changed by calling

[self changePage:UIPageViewControllerNavigationDirectionReverse];
[self changePage:UIPageViewControllerNavigationDirectionForward];

You can now (as of Webpack v5.0.0) specify a unique output path for each entry using the new "descriptor" syntax (https://webpack.js.org/configuration/entry-context/#entry-descriptor) –

module.exports = {
  entry: {
    home: { import: './home.js', filename: 'unique/path/1/[name][ext]' },
    about: { import: './about.js', filename: 'unique/path/2/[name][ext]' }
  }
};

PDFBox is the best library I've found for this purpose, it's comprehensive and really quite easy to use if you're just doing basic text extraction. Examples can be found here.

It explains it on the page, but one thing to watch out for is that the start and end indexes when using setStartPage() and setEndPage() are both inclusive. I skipped over that explanation first time round and then it took me a while to realise why I was getting more than one page back with each call!

Itext is another alternative that also works with C#, though I've personally never used it. It's more low level than PDFBox, so less suited to the job if all you need is basic text extraction.

How about:

df['new_col'] = range(1, len(df) + 1)

Alternatively if you want the index to be the ranks and store the original index as a column:

df = df.reset_index()

This function will return a converted java date from SQL date object.

public static java.util.Date convertFromSQLDateToJAVADate(
            java.sql.Date sqlDate) {
        java.util.Date javaDate = null;
        if (sqlDate != null) {
            javaDate = new Date(sqlDate.getTime());
        }
        return javaDate;
    }

Install a cross compiler, like mingw64 from your package manager. Then compile in the following way: instead of simply calling gcc call i686-w64-mingw32-gcc for 32-bit Windows or x86_64-w64-mingw32-gcc" for 64-bit Windows. I would also use the --static option, as the target system may not have all the libraries.

If you want to compile other language, like Fortran, replace -gcc with -gfortran in the previous commands.

I know I'm a little late, but something I found that works (and doesn't require using csv) is to write a for loop that writes to your file for every element in your list.

# Define Data
RESULTS = ['apple','cherry','orange','pineapple','strawberry']

# Open File
resultFyle = open("output.csv",'w')

# Write data to file
for r in RESULTS:
    resultFyle.write(r + "\n")
resultFyle.close()

I don't know if this solution is any better than the ones already offered, but it more closely reflects your original logic so I thought I'd share.

I too had the same issue. I changed the codec to H264-MPEG-4 AVC and the videos started working in HTML5/Chrome.

Option selected in converter: H264-MPEG-4 AVC, Codec visible in VLC player: H264-MPEG-4 AVC (part 10) (avc1)

Hope it helps...

try

if (readData is T)
    return (T)(object)readData;

wrap you shared code into another function:

<script>
  function myFun () {
      //do something
  }

  $(document).ready(function(){
    //Load City by State
    $(document).on('change', '#billing_state_id', function() {
       myFun ();
    });   
    $(document).on('click', '#click_me', function() {
       //do something
       myFun();
    });   
  });
</script>

I had this same issue and a couple others being reported for a existing maven project.

I had the proper dependencies in place and I could see the jar under maven dependencies, however the project was improperly brought into eclipse.

I ended up having to delete the project, clone from git again then do an import of the project as an existing maven project.

This solved the issue in this thread and several others issues I was having. More details on solution can be found here: Maven Project in Eclipse `org.springframework cannot be resolved to a type` from target path

works for me

I tried all the solutions but it still wasn't sufficient. After some more digging I eventually found I had also to set the 'file_priv' flag, and restart mysql.

To resume :

Grant the privileges :

> GRANT ALL PRIVILEGES
  ON my_database.* 
  to 'my_user'@'localhost';

> GRANT FILE ON *.* TO my_user;

> FLUSH PRIVILEGES; 

Set the flag :

> UPDATE mysql.user SET File_priv = 'Y' WHERE user='my_user' AND host='localhost';

Finally restart the mysql server:

$ sudo service mysql restart

After that, I could write into the secure_file_priv directory. For me it was /var/lib/mysql-files/, but you can check it with the following command :

> SHOW VARIABLES LIKE "secure_file_priv";

First, as for your Athlete class, you can remove your Getter and Setter methods since you have declared your instance variables with an access modifier of public. You can access the variables via <ClassName>.<variableName>.

However, if you really want to use that Getter and Setter, change the public modifier to private instead.

Second, for the constructor, you're trying to do a simple technique called shadowing. Shadowing is when you have a method having a parameter with the same name as the declared variable. This is an example of shadowing:
----------Shadowing sample----------
You have the following class:

public String name;

public Person(String name){
    this.name = name; // This is Shadowing
}

In your main method for example, you instantiate the Person class as follow:
Person person = new Person("theolc");

Variable name will be equal to "theolc".
----------End of shadowing----------

Let's go back to your question, if you just want to print the first element with your current code, you may remove the Getter and Setter. Remove your parameters on your constructor.

public class Athlete {

public String[] name = {"Art", "Dan", "Jen"};
public String[] country = {"Canada", "Germany", "USA"};

public Athlete() {

}

In your main method, you could do this.

public static void main(String[] args) {
       Athlete art = new Athlete();   

       System.out.println(art.name[0]);
       System.out.println(art.country[0]);
    }
}

The idea of refresh tokens is that if an access token is compromised, because it is short-lived, the attacker has a limited window in which to abuse it.

Refresh tokens, if compromised, are useless because the attacker requires the client id and secret in addition to the refresh token in order to gain an access token.

Having said that, because every call to both the authorization server and the resource server is done over SSL - including the original client id and secret when they request the access/refresh tokens - I am unsure as to how the access token is any more "compromisable" than the long-lived refresh token and clientid/secret combination.

This of course is different to implementations where you don't control both the authorization and resource servers.

Here is a good thread talking about uses of refresh tokens: OAuth Archives.

A quote from the above, talking about the security purposes of the refresh token:

Refresh tokens... mitigates the risk of a long-lived access_token leaking (query param in a log file on an insecure resource server, beta or poorly coded resource server app, JS SDK client on a non https site that puts the access_token in a cookie, etc)

I found this on a Microsoft Support page http://support.microsoft.com/kb/2019698.

It works great! And since it came from Microsoft, I feel like it's pretty legit.

Basically there are two steps.

1. Create a stored procedure in your master db. See msft link or if it's broken try here: http://pastebin.com/svRLkqnq

2. Schedule the backup from your task scheduler. You might want to put into a .bat or .cmd file first and then schedule that file.

   sqlcmd -S YOUR_SERVER_NAME\SQLEXPRESS -E -Q "EXEC sp_BackupDatabases @backupLocation='C:\SQL_Backup\', @backupType='F'"  1>c:\SQL_Backup\backup.log            
   

Obviously replace YOUR_SERVER_NAME with your computer name or optionally try .\SQLEXPRESS and make sure the backup folder exists. In this case it's trying to put it into c:\SQL_Backup

You can try this

<a [attr.disabled]="someCondition ? true: null"></a>

You can just use the output of is.na to replace directly with subsetting:

bothbeams.data[is.na(bothbeams.data)] <- 0

Or with a reproducible example:

dfr <- data.frame(x=c(1:3,NA),y=c(NA,4:6))
dfr[is.na(dfr)] <- 0
dfr
  x y
1 1 0
2 2 4
3 3 5
4 0 6

However, be careful using this method on a data frame containing factors that also have missing values:

> d <- data.frame(x = c(NA,2,3),y = c("a",NA,"c"))
> d[is.na(d)] <- 0
Warning message:
In `[<-.factor`(`*tmp*`, thisvar, value = 0) :
  invalid factor level, NA generated

It "works":

> d
  x    y
1 0    a
2 2 <NA>
3 3    c

...but you likely will want to specifically alter only the numeric columns in this case, rather than the whole data frame. See, eg, the answer below using dplyr::mutate_if.

If I understand correctly you want to exclude files from the vscode fuzzy finder. If that is the case, I am guessing the above answers are for older versions of vscode. What worked for me is adding:

"files.exclude": {
    "**/directory-you-want-to-exclude": true,
    "**/.git": true,
    "**/.svn": true,
    "**/.hg": true,
    "**/CVS": true,
    "**/.DS_Store": true
}

to my settings.json. This file can be opened through File>Preferences>Settings

Try this: Create a plain div without any style or content outside of the red div. Now you can use a loop over all styles of the plain div and assign then to your inner div to reset all styles.

Of course this doesn't work if someone assigns styles to all divs (i.e. without using a class. CSS would be div { ... }).

The usual solution for problems like this is to give your div a distinct class. That way, web designers of the sites can adjust the styling of your div to fit into the rest of the design.

You can use

window.clipboardData.getData('Text')

to get the content of user's clipboard in IE. However, in other browser you may need to use flash to get the content, since there is no standard interface to access the clipboard. May be you can have try this plugin Zero Clipboard

I've found the following "pattern" to be very useful:

MainCtrl.$inject = ['$scope', '$rootScope', '$location', 'socket', ...];
function MainCtrl (scope, rootscope, location, thesocket, ...) {

where, MainCtrl is a controller. I am uncomfortable relying on the parameter names of the Controller function doing a one-for-one mimic of the instances for fear that I might change names and muck things up. I much prefer explicitly using $inject for this purpose.

5 Columns with Bootstrap 4

Here is 5 equal, full-width columns (no extra CSS or SASS) using the auto-layout grid..

<div class="container-fluid">
    <div class="row">
        <div class="col">1</div>
        <div class="col">2</div>
        <div class="col">3</div>
        <div class="col">4</div>
        <div class="col">5</div>
    </div>
</div>

http://codeply.com/go/MJTglTsq9h

This solution works because Bootstrap 4 is now flexbox. You can get the 5 colums to wrap within the same .row using a clearfix break such as <div class="col-12"></div> or <div class="w-100"></div> very 5 columns.

Update 2020

As of Bootstrap 4.4, you can also use the row-cols-5 class on the row...

<div class="container">
    <div class="row row-cols-5">
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
        <div class="col">
            X
        </div>
    </div>
</div>

PHP Manual says:

gethostname (PHP >= 5.3.0) gethostname — Gets the host name

Look:

<?php
echo gethostname(); // may output e.g,: sandie
// Or, an option that also works before PHP 5.3
echo php_uname('n'); // may output e.g,: sandie
?>

To extend the answer above and if the case is you are using XAMPP. In the current version of the xampp you cannot locate the curl_exec in the php.ini, just try using

<?php
echo '<pre>';
var_dump(curl_version());
echo '</pre>';
?>

and save to your htdocs. Next go to your browser and paste

http://localhost/[your_filename].php

if the result looks like this

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

We at Teleport just started opening up our API's and one of the usecases is also exposing TZ information for coordinates.

For example one could request all our available TZ information for coordinates in following manner:

curl -s https://api.teleport.org/api/locations/59.4372,24.7453/?embed=location:nearest-cities/location:nearest-city/city:timezone/tz:offsets-now | jq '._embedded."location:nearest-cities"[0]._embedded."location:nearest-city"._embedded."city:timezone"'

This would return the following

{
  "_embedded": {
    "tz:offsets-now": {
      "_links": {
        "self": {
          "href": "https://api.teleport.org/api/timezones/iana:Europe%2FTallinn/offsets/?date=2015-09-07T11%3A20%3A09Z"
        }
      },
      "base_offset_min": 120,
      "dst_offset_min": 60,
      "end_time": "2015-10-25T01:00:00Z",
      "short_name": "EEST",
      "total_offset_min": 180,
      "transition_time": "2015-03-29T01:00:00Z"
    }
  },
  "_links": {
    "self": {
      "href": "https://api.teleport.org/api/timezones/iana:Europe%2FTallinn/"
    },
    "tz:offsets": {
      "href": "https://api.teleport.org/api/timezones/iana:Europe%2FTallinn/offsets/{?date}",
      "templated": true
    },
    "tz:offsets-now": {
      "href": "https://api.teleport.org/api/timezones/iana:Europe%2FTallinn/offsets/?date=2015-09-07T11%3A20%3A09Z"
    }
  },
  "iana_name": "Europe/Tallinn"
}

For the example I used ./jq for JSON parsing.

I have got the same issue when tried to get users information without auth.

Check if you have loggen in before any request.

 $uid = $facebook->getUser();

 if ($uid){
      $me = $facebook->api('/me');
 }

The code above should solve your issue.

I have 1 simpler work around...

What you can do is while inserting data/document into your main collection "things" you must insert the attributes in 1 separate collection lets say "things_attributes".

so every time you insert in "things", you do get from "things_attributes" compare values of that document with your new document keys if any new key present append it in that document and again re-insert it.

So things_attributes will have only 1 document of unique keys which you can easily get when ever you require by using findOne()

I just add a static method to call it like a MessageBox:

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    x:Class="utils.PromptDialog"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    WindowStartupLocation="CenterScreen" 
    SizeToContent="WidthAndHeight"
    MinWidth="300"
    MinHeight="100"
    WindowStyle="SingleBorderWindow"
    ResizeMode="CanMinimize">
<StackPanel Margin="5">
    <TextBlock Name="txtQuestion" Margin="5"/>
    <TextBox Name="txtResponse" Margin="5"/>
    <PasswordBox Name="txtPasswordResponse" />
    <StackPanel Orientation="Horizontal" Margin="5" HorizontalAlignment="Right">
        <Button Content="_Ok" IsDefault="True" Margin="5" Name="btnOk" Click="btnOk_Click" />
        <Button Content="_Cancel" IsCancel="True" Margin="5" Name="btnCancel" Click="btnCancel_Click" />
    </StackPanel>
</StackPanel>
</Window>

And the code behind:

public partial class PromptDialog : Window
{
    public enum InputType
    {
        Text,
        Password
    }

    private InputType _inputType = InputType.Text;

    public PromptDialog(string question, string title, string defaultValue = "", InputType inputType = InputType.Text)
    {
        InitializeComponent();
        this.Loaded += new RoutedEventHandler(PromptDialog_Loaded);
        txtQuestion.Text = question;
        Title = title;
        txtResponse.Text = defaultValue;
        _inputType = inputType;
        if (_inputType == InputType.Password)
            txtResponse.Visibility = Visibility.Collapsed;
        else
            txtPasswordResponse.Visibility = Visibility.Collapsed;
    }

    void PromptDialog_Loaded(object sender, RoutedEventArgs e)
    {
        if (_inputType == InputType.Password)
            txtPasswordResponse.Focus();
        else
            txtResponse.Focus();
    }

    public static string Prompt(string question, string title, string defaultValue = "", InputType inputType = InputType.Text)
    {
        PromptDialog inst = new PromptDialog(question, title, defaultValue, inputType);
        inst.ShowDialog();
        if (inst.DialogResult == true)
            return inst.ResponseText;
        return null;
    }

    public string ResponseText
    {
        get
        {
            if (_inputType == InputType.Password)
                return txtPasswordResponse.Password;
            else
                return txtResponse.Text;
        }
    }

    private void btnOk_Click(object sender, RoutedEventArgs e)
    {
        DialogResult = true;
        Close();
    }

    private void btnCancel_Click(object sender, RoutedEventArgs e)
    {
        Close();
    }
}

So you can call it like:

string repeatPassword = PromptDialog.Prompt("Repeat password", "Password confirm", inputType: PromptDialog.InputType.Password);

The best way to generate the unique random number is

<?php
     echo md5(uniqid(mt_rand(), true).microtime(true));
?>

Since I just learned about this cool thing(indexing into lists from within a format string) I'm adding to this old question.

s = '{x[0]} BLAH {x[1]} FOO {x[2]} BAR'
x = ['1', '2', '3']
print (s.format (x=x))

Output:

1 BLAH 2 FOO 3 BAR

However, I still haven't figured out how to do slicing(inside of the format string '"{x[2:4]}".format...,) and would love to figure it out if anyone has an idea, however I suspect that you simply cannot do that.

I had the same "TypeError: an integer is required" error message when attempting to write. Thanks, the .encode() solved it for me. I'm running python 3.4 on a Dell D530 running 32 bit Windows XP Pro.

I'm omitting the com port settings here:

>>>import serial

>>>ser = serial.Serial(5)

>>>ser.close()

>>>ser.open()

>>>ser.write("1".encode())

1

>>>

use like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dedline);

    WebView myWebView = (WebView) findViewById(R.id.webView1);
    myWebView.setWebViewClient(new WebViewClient());
    myWebView.loadUrl("https://google.com");
}

You can iterate through the key-value pair and write it into file

pair = {'name': name,'location': location}
with open('F:\\twitter.json', 'a') as f:
     f.writelines('{}:{}'.format(k,v) for k, v in pair.items())
     f.write('\n')
