Programs & Examples On #Paragraph

Although your answer has many solutions I think this is a great way to save lines of code. Try using spans which is great for situations like yours.

1. Create a class for making any item bold. So for paragraph text it would be

span.bold(This name can be anything do not include parenthesis) {
   font-weight: bold;
}

1. In your html you can access that class like by using the span tags and adding a class of bold or whatever name you have chosen

Across the internet, people have noticed that setting config.enterMode to CKEDITOR.ENTER_BR removes the wrapping paragraph tags from CKEditor. It's worth noting that the setting changes the behavior of the enter key to insert line breaks rather than paragraphs, which is not desirable.

See: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.enterMode "It is recommended to use the CKEDITOR.ENTER_P setting because of its semantic value and correctness."

However, the setting that is designed to remove that initial paragraph, config.autoParagraph, isn't advisable either, as it introduces "unpredictable usability issues" because the editor really wants a top-level block element.

See: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.autoParagraph

The magic happens on wysiwygarea/plugin.js, line 410, where the editor selects the default block element based on config.enterMode. A config option to change the default block element would allow us to start with a div, but we'd continue getting more divs with every enter press, unless we changed the paragraph format via the menu.

See: http://docs.cksource.com/ckeditor_api/symbols/src/plugins_wysiwygarea_plugin.js.html

It would be possible to remove the wrapping paragraph tag with post-processing (either on the server or in CKEditor's getData event), but that leads us into the same problem as disabling autoParagraph: there's no top-level block.

I would rather say that there's not a good solution, but rather a handful of half-solutions, than to accept changing config.enterMode as the canonical solution.

Use jQuery:

$("li").find("p").html()

should work.

Can be as easy as:

var ms = new MemoryStream(imageData);
System.Drawing.Image image = Image.FromStream(ms);

image.Save("c:\\image.jpg");

Testing it out:

byte[] imageData;

// Create the byte array.
var originalImage = Image.FromFile(@"C:\original.jpg");
using (var ms = new MemoryStream())
{
    originalImage.Save(ms, ImageFormat.Jpeg);
    imageData = ms.ToArray();
}

// Convert back to image.
using (var ms = new MemoryStream(imageData))
{
    Image image = Image.FromStream(ms);
    image.Save(@"C:\newImage.jpg");
}

You cannot directly create a table stored as a sequence file and insert text into it. You must do this:

1. Create a table stored as text
2. Insert the text file into the text table
3. Do a CTAS to create the table stored as a sequence file.
4. Drop the text table if desired

Example:

CREATE TABLE test_txt(field1 int, field2 string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';

LOAD DATA INPATH '/path/to/file.tsv' INTO TABLE test_txt;

CREATE TABLE test STORED AS SEQUENCEFILE
AS SELECT * FROM test_txt;

DROP TABLE test_txt;

Use IFNULL or COALESCE:

SELECT IFNULL(SUM(Column1), 0) AS total FROM...

SELECT COALESCE(SUM(Column1), 0) AS total FROM...

The difference between them is that IFNULL is a MySQL extension that takes two arguments, and COALESCE is a standard SQL function that can take one or more arguments. When you only have two arguments using IFNULL is slightly faster, though here the difference is insignificant since it is only called once.

Use sleep like so:

sleep 2

That'll sleep for 2 seconds.

Be careful to give an argument. If you just run sleep, the process will sleep forever. (This is useful when you want a thread to sleep until it's woken.)

var date=new Date();

//here I am using "-30" to subtract 30 minutes from the current time.
var minute=date.setMinutes(date.getMinutes()-30); 

console.log(minute) //it will print the time and date according to the above condition in Unix-timestamp format.

you can convert Unix timestamp into conventional time by using new Date().for example

var extract=new Date(minute)
console.log(minute)//this will print the time in the readable format.

Here you go this should give you the correct answers every time!

a = int(input("Enter the coefficients of a: "))
b = int(input("Enter the coefficients of b: "))
c = int(input("Enter the coefficients of c: "))

d = b**2-4*a*c # discriminant

if d < 0:
    print ("This equation has no real solution")
elif d == 0:
    x = (-b+math.sqrt(b**2-4*a*c))/2*a
    print ("This equation has one solutions: "), x
else:
    x1 = (-b+math.sqrt((b**2)-(4*(a*c))))/(2*a)
    x2 = (-b-math.sqrt((b**2)-(4*(a*c))))/(2*a)
    print ("This equation has two solutions: ", x1, " or", x2)

I extended this question that is how to gets the row, columnand value of all matches value?

here is solution:

import pandas as pd
import numpy as np


def search_coordinate(df_data: pd.DataFrame, search_set: set) -> list:
    nda_values = df_data.values
    tuple_index = np.where(np.isin(nda_values, [e for e in search_set]))
    return [(row, col, nda_values[row][col]) for row, col in zip(tuple_index[0], tuple_index[1])]


if __name__ == '__main__':
    test_datas = [['cat', 'dog', ''],
                  ['goldfish', '', 'kitten'],
                  ['Puppy', 'hamster', 'mouse']
                  ]
    df_data = pd.DataFrame(test_datas)
    print(df_data)
    result_list = search_coordinate(df_data, {'dog', 'Puppy'})
    print(f"\n\n{'row':<4} {'col':<4} {'name':>10}")
    [print(f"{row:<4} {col:<4} {name:>10}") for row, col, name in result_list]

Output:

          0        1       2
0       cat      dog        
1  goldfish           kitten
2     Puppy  hamster   mouse


row  col        name
0    1           dog
2    0         Puppy

You can use a simple API from http://www.geoplugin.net/

$xml = simplexml_load_file("http://www.geoplugin.net/xml.gp?ip=".getRealIpAddr());
echo $xml->geoplugin_countryName ;


echo "<pre>";
foreach ($xml as $key => $value)
{
    echo $key , "= " , $value ,  " \n" ;
}
echo "</pre>";

Function Used

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}

Output

It makes you have so many options you can play around with

Thanks

Some answers overcomplicate the scenario here. This is a dead simple situation.

Just answer to this question every time you'd like to place an image:

Is this part of the content or part of the design?

If you can't answer this, you probably don't know what you're doing or what you want to do!

Also, DO NOT consider beside the two technique, just because you'd wish to be "printer friendly" or not. Also DO NOT hide content from a SEO point of view with CSS. If you find yourself managing your content in CSS files, you shot yourself in the leg. This is just a trivial decision of what is content or not. Every other aspect should be ignored.

DocumentElement is the root node of the document so childNodes[1] doesn't exist in that document. childNodes[0] would be the <Settings> node

You can use following git command to clone with custom directory name

git clone <git_repo_url> <your_custom_directory_name>

Note: You don't need to create your custom directory because it will create automatically

Thanks to @IanRoberts, I had to use the normalize-space function on my nodes to check if they were empty.

<xsl:if test="((node/ABC!='') and (normalize-space(node/DEF)='') and (normalize-space(node/GHI)=''))">
  This worked perfectly fine.
</xsl:if>

To find the next element with the same class:

$(".class").eq( $(".class").index( $(element) ) + 1 )

I think your second option is the best bet. Generally in floating-point comparison you often only care that one value is within a certain tolerance of another value, controlled by the selection of epsilon.

If you really want to "ExecuteCall a shell script in current shell with sudo permission" you can use exec to...

replace the shell with a given program (executing it, not as new process)

I insist on replacing "execute" with "call" because the former has a meaning that includes creating a new process and ID, where the latter is ambiguous and leaves room for creativity, of which I am full.

Consider this test case and look closely at pid 1337

# Don't worry, the content of this script is cat'ed below
$ ./test.sh -o foo -p bar

User ubuntu is running...
 PID TT       USER     COMMAND
 775 pts/1    ubuntu   -bash
1408 pts/1    ubuntu    \_ bash ./test.sh -o foo -p bar
1411 pts/1    ubuntu        \_ ps -t /dev/pts/1 -fo pid,tty,user,args

User root is running...
 PID TT       USER     COMMAND
 775 pts/1    ubuntu   -bash
1337 pts/1    root      \_ sudo ./test.sh -o foo -p bar
1412 pts/1    root          \_ bash ./test.sh -o foo -p bar
1415 pts/1    root              \_ ps -t /dev/pts/1 -fo pid,tty,user,args

Take 'exec' out of the command and this script would get cat-ed twice. (Try it.)

#!/usr/bin/env bash

echo; echo "User $(whoami) is running..."
ps -t $(tty) -fo pid,tty,user,args

if [[ $EUID > 0 ]]; then
    # exec replaces the current process effectively ending execution so no exit is needed.
    exec sudo "$0" "$@"
fi

echo; echo "Take 'exec' out of the command and this script would get cat-ed twice. (Try it.)"; echo
cat $0

Here is another test using sudo -s

$ ps -fo pid,tty,user,args; ./test2.sh
  PID TT       USER     COMMAND
10775 pts/1    ubuntu   -bash
11496 pts/1    ubuntu    \_ ps -fo pid,tty,user,args

User ubuntu is running...
  PID TT       USER     COMMAND
10775 pts/1    ubuntu   -bash
11497 pts/1    ubuntu    \_ bash ./test2.sh
11500 pts/1    ubuntu        \_ ps -fo pid,tty,user,args

User root is running...
  PID TT       USER     COMMAND
11497 pts/1    root     sudo -s
11501 pts/1    root      \_ /bin/bash
11503 pts/1    root          \_ ps -fo pid,tty,user,args

$ cat test2.src
echo; echo "User $(whoami) is running..."
ps -fo pid,tty,user,args

$ cat test2.sh
#!/usr/bin/env bash

source test2.src

exec sudo -s < test2.src

And a simpler test using sudo -s

$ ./exec.sh
bash's PID:25194    user ID:7809
systemd(1)---bash(23064)---bash(25194)---pstree(25196)

Finally...
bash's PID:25199    user ID:0
systemd(1)---bash(23064)---sudo(25194)---bash(25199)---pstree(25201)

$ cat exec.sh
#!/usr/bin/env bash

pid=$$
id=$(id -u)
echo "bash's PID:$pid    user ID:$id"
pstree -ps $pid

# the quoted EOF is important to prevent shell expansion of the $...
exec sudo -s <<EOF
echo
echo "Finally..."
echo "bash's PID:\$\$    user ID:\$(id -u)"
pstree -ps $pid
EOF

One way would be:

while read NAME
do
    echo "$NAME"
done < names.txt

EDIT: Note that the loop gets executed in a sub-shell, so any modified variables will be local, except if you declare them with declare outside the loop.

Dennis Williamson is right. Sorry, must have used piped constructs too often and got confused.

Just wondering why you are using 2 directives?

It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.

Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).

It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.

Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

The problem you are reporting seems to me caused by the following:

1. you are trying to compile C code and the source file has .cpp extension
2. you are trying to compile C++ code and the source file has .c extension

In such situation Eclipse cannot recognize the proper compiler to use.

1. Stop ZooKeeper and Kafka
2. In server.properties, change log.retention.hours value. You can comment log.retention.hours and add log.retention.ms=1000. It would keep the record on Kafka Topic for only one second.
3. Start zookeeper and kafka.
4. Check on consumer console. When I opened the console for the first time, record was there. But when I opened the console again, the record was removed.
5. Later on, you can set the value of log.retention.hours to your desired figure.

H2CO3 is right, you can use a makefile with the CXXFLAGS set with -std=c++11 A makefile is a simple text file with instructions about how to compile your program. Create a new file named Makefile (with a capital M). To automatically compile your code just type the make command in a terminal. You may have to install make.

Here's a simple one :

CXX=clang++
CXXFLAGS=-g -std=c++11 -Wall -pedantic
BIN=prog

SRC=$(wildcard *.cpp)
OBJ=$(SRC:%.cpp=%.o)

all: $(OBJ)
    $(CXX) -o $(BIN) $^

%.o: %.c
    $(CXX) $@ -c $<

clean:
    rm -f *.o
    rm $(BIN)

It assumes that all the .cpp files are in the same directory as the makefile. But you can easily tweak your makefile to support a src, include and build directories.

Edit : I modified the default c++ compiler, my version of g++ isn't up-to-date. With clang++ this makefile works fine.

If your .NET version is newer than 3.0 you can try using System.Xml.Linq.XDocument instead of XmlDocument. It is easier to process data with XDocument.

There is a helpful function in the psych package.

You should try the following implementation:

psych::describeBy(data$dependentvariable, group = data$groupingvariable)

This is NOT my work, found the answer here. did not want a broken link in the future :).

The key is this line for taking daylight setting into account, ref Full Code.

TimeZone.setDefault(TimeZone.getTimeZone("Europe/London"));

or try passing TimeZone as a parameter to daysBetween() and call setTimeZone() in the sDate and eDate objects.

So here it goes:

public static Calendar getDatePart(Date date){
    Calendar cal = Calendar.getInstance();       // get calendar instance
    cal.setTime(date);      
    cal.set(Calendar.HOUR_OF_DAY, 0);            // set hour to midnight
    cal.set(Calendar.MINUTE, 0);                 // set minute in hour
    cal.set(Calendar.SECOND, 0);                 // set second in minute
    cal.set(Calendar.MILLISECOND, 0);            // set millisecond in second
    
    return cal;                                  // return the date part
}

getDatePart() taken from here

/**
 * This method also assumes endDate >= startDate
**/
public static long daysBetween(Date startDate, Date endDate) {
  Calendar sDate = getDatePart(startDate);
  Calendar eDate = getDatePart(endDate);

  long daysBetween = 0;
  while (sDate.before(eDate)) {
      sDate.add(Calendar.DAY_OF_MONTH, 1);
      daysBetween++;
  }
  return daysBetween;
}

The Nuances: Finding the difference between two dates isn't as straightforward as subtracting the two dates and dividing the result by (24 * 60 * 60 * 1000). Infact, its erroneous!

For example: The difference between the two dates 03/24/2007 and 03/25/2007 should be 1 day; However, using the above method, in the UK, you'll get 0 days!

See for yourself (code below). Going the milliseconds way will lead to rounding off errors and they become most evident once you have a little thing like Daylight Savings Time come into the picture.

Full Code:

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.TimeZone;

public class DateTest {

public class DateTest {

static SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy");

public static void main(String[] args) {

  TimeZone.setDefault(TimeZone.getTimeZone("Europe/London"));

  //diff between these 2 dates should be 1
  Date d1 = new Date("01/01/2007 12:00:00");
  Date d2 = new Date("01/02/2007 12:00:00");

  //diff between these 2 dates should be 1
  Date d3 = new Date("03/24/2007 12:00:00");
  Date d4 = new Date("03/25/2007 12:00:00");

  Calendar cal1 = Calendar.getInstance();cal1.setTime(d1);
  Calendar cal2 = Calendar.getInstance();cal2.setTime(d2);
  Calendar cal3 = Calendar.getInstance();cal3.setTime(d3);
  Calendar cal4 = Calendar.getInstance();cal4.setTime(d4);

  printOutput("Manual   ", d1, d2, calculateDays(d1, d2));
  printOutput("Calendar ", d1, d2, daysBetween(cal1, cal2));
  System.out.println("---");
  printOutput("Manual   ", d3, d4, calculateDays(d3, d4));
  printOutput("Calendar ", d3, d4, daysBetween(cal3, cal4));
}


private static void printOutput(String type, Date d1, Date d2, long result) {
  System.out.println(type+ "- Days between: " + sdf.format(d1)
                    + " and " + sdf.format(d2) + " is: " + result);
}

/** Manual Method - YIELDS INCORRECT RESULTS - DO NOT USE**/
/* This method is used to find the no of days between the given dates */
public static long calculateDays(Date dateEarly, Date dateLater) {
  return (dateLater.getTime() - dateEarly.getTime()) / (24 * 60 * 60 * 1000);
}

/** Using Calendar - THE CORRECT WAY**/
public static long daysBetween(Date startDate, Date endDate) {
  ...
}

OUTPUT:

Manual - Days between: 01-Jan-2007 and 02-Jan-2007 is: 1

I use Xamarin with Visual Studio, and I prefer to move only some large android to another directory with(copy these folders to destination before create hardlinks):

mklink \J "C:\Users\yourUser\.android" "E:\yourFolder\.android"

mklink \J "C:\Program Files (x86)\Android" "E:\yourFolder\Android"

We had a problem with APC and symlinks to symlinks to files -- it seems to ignore changes in files itself. Somehow performing touch on the file itself helped. I can not tell what's the difference between modifing a file and touching it, but somehow it was necessary...

Hi try with this overflow-y: scroll. I hope it may helps you

One way:

def change(f):
    if f is None:
        return unicode(f.strip())
    else:
        return ''

row = [change(x) for x in row]

Although then you have:

row = map(change, row)

Or you can use a lambda inline.

var strcmp = new Intl.Collator(undefined, {numeric:true, sensitivity:'base'}).compare;

Usage: strcmp(string1, string2)

Result: 1 means string1 is bigger, 0 means equal, -1 means string2 is bigger.

This has higher performance than String.prototype.localeCompare

Also, numeric:true makes it do logical number comparison

They are 3 ways you can achieve this using the py command (py-launcher) in python 3, virtual environment or configuring your default python system path. For illustration purpose, you may see tutorial https://www.youtube.com/watch?v=ynDlb0n27cw&t=38s

I use msysgit to install gcc on Windows, it has a nice installer which installs most everything that you might need. Most devs will need more than just the compiler, e.g. the shell, shell tools, make, git, svn, etc. msysgit comes with all of that. https://msysgit.github.io/

edit: I am now using msys2. Msys2 uses pacman from Arch Linux to install packages, and includes three environments, for building msys2 apps, 32-bit native apps, and 64-bit native apps. (You probably want to build 32-bit native apps.)

https://msys2.github.io/

You could also go full-monty and install code::blocks or some other gui editor that comes with a compiler. I prefer to use vim and make.

A roll your own function.

Supports recursion or not with the 2nd switch.

Also, allow names of files with ; which the accepted answer fails to address although a great answer, this will get over that issue.

The idea was taken from https://ss64.com/nt/empty.html

There is a way that's pretty memory inefficient.

single file:

import hashlib
def file_as_bytes(file):
    with file:
        return file.read()

print hashlib.md5(file_as_bytes(open(full_path, 'rb'))).hexdigest()

list of files:

[(fname, hashlib.md5(file_as_bytes(open(fname, 'rb'))).digest()) for fname in fnamelst]

Recall though, that MD5 is known broken and should not be used for any purpose since vulnerability analysis can be really tricky, and analyzing any possible future use your code might be put to for security issues is impossible. IMHO, it should be flat out removed from the library so everybody who uses it is forced to update. So, here's what you should do instead:

[(fname, hashlib.sha256(file_as_bytes(open(fname, 'rb'))).digest()) for fname in fnamelst]

If you only want 128 bits worth of digest you can do .digest()[:16].

This will give you a list of tuples, each tuple containing the name of its file and its hash.

Again I strongly question your use of MD5. You should be at least using SHA1, and given recent flaws discovered in SHA1, probably not even that. Some people think that as long as you're not using MD5 for 'cryptographic' purposes, you're fine. But stuff has a tendency to end up being broader in scope than you initially expect, and your casual vulnerability analysis may prove completely flawed. It's best to just get in the habit of using the right algorithm out of the gate. It's just typing a different bunch of letters is all. It's not that hard.

Here is a way that is more complex, but memory efficient:

import hashlib

def hash_bytestr_iter(bytesiter, hasher, ashexstr=False):
    for block in bytesiter:
        hasher.update(block)
    return hasher.hexdigest() if ashexstr else hasher.digest()

def file_as_blockiter(afile, blocksize=65536):
    with afile:
        block = afile.read(blocksize)
        while len(block) > 0:
            yield block
            block = afile.read(blocksize)


[(fname, hash_bytestr_iter(file_as_blockiter(open(fname, 'rb')), hashlib.md5()))
    for fname in fnamelst]

And, again, since MD5 is broken and should not really ever be used anymore:

[(fname, hash_bytestr_iter(file_as_blockiter(open(fname, 'rb')), hashlib.sha256()))
    for fname in fnamelst]

Again, you can put [:16] after the call to hash_bytestr_iter(...) if you only want 128 bits worth of digest.

Another easy way to do this is to place your UIImageView within a UIScrollView. As I describe here, you need to set the scroll view's contentSize to be the same as your UIImageView's size. Set your controller instance to be the delegate of the scroll view and implement the viewForZoomingInScrollView: and scrollViewDidEndZooming:withView:atScale: methods to allow for pinch-zooming and image panning. This is effectively what Ben's solution does, only in a slightly more lightweight manner, as you don't have the overhead of a full web view.

One issue you may run into is that the scaling within the scroll view comes in the form of transforms applied to the image. This may lead to blurriness at high zoom factors. For something that can be redrawn, you can follow my suggestions here to provide a crisper display after the pinch gesture is finished. hniels' solution could be used at that point to rescale your image.

we can access/pass arguments/variables from one class to another class using object reference.

#Class1
class Test:
    def __init__(self):
        self.a = 10
        self.b = 20
        self.add = 0

    def calc(self):
        self.add = self.a+self.b

#Class 2
class Test2:
    def display(self):
        print('adding of two numbers: ',self.add)
#creating object for Class1
obj = Test()
#invoking calc method()
obj.calc()
#passing class1 object to class2
Test2.display(obj)

Another example:

Dim myPath As String = """" & Path.Combine(part1, part2) & """"

Good luck!

JSONObject metadata = (JSONObject) data.get("map"); //for example
String jsonString = metadata.**toJSONString()**;

In one-step w/admin credentials:

Add-Computer -DomainName xxxx -ComputerName xxxx -NewName xxxx -Credential Domain\Admin -Restart

-DomainName = Your domain name (e.g. corp.local)

-ComputerName = Name of your local computer (e.g. The computer you are on. Use "Hostname" in PS to find out name).

-NewName = What you want to rename the computer (e.g. CORP-ANNE-TX)

-Credentials = Your admin credentials that give you authorization to perform this action (e.g. Domain\Admin = example Corp\JSmith. A dialog box will appear to put in your password)

In two-steps:

Step 1

Rename-Computer -NewName xxxx -Restart

Here you do not have to put -ComputerName as it assumes you are at the local computer. If doing this remotely; different story.

Step 2

Add-Computer -DomainName xxxx -Credential xxxx\xxxxx -Restart

xxxx\xxxx = Your domain and admin username (e.g. Corp\Jsmith)

Keep an index of the first "live" element of the array. Removing (pretending to remove) the first element then becomes an O(1) time complexity operation.

There is the GeoLocation API, but browser support is rather thin on the ground at present. Most sites that care about such things use a GeoIP database (with the usual provisos about the inaccuracy of such a system). You could also look at third party services requiring user cooperation such as FireEagle.

range() and xrange() take a third parameter that specifies a step. So you can do the following.

range(10, 0, -1)

Which gives

[10, 9, 8, 7, 6, 5, 4, 3, 2, 1] 

But for iteration, you should really be using xrange instead. So,

xrange(10, 0, -1)

Note for Python 3 users: There are no separate range and xrange functions in Python 3, there is just range, which follows the design of Python 2's xrange.

Try this

function pad (str, max) {
  return str.length < max ? pad("0" + str, max) : str;
}

alert(pad("5", 2));

Example

http://jsfiddle.net/

Or

var number = 5;
var i;
if (number < 10) {
    alert("0"+number);
}

In general I fully agree with Jason's use of css selector, but in some cases you may not want to change the css, e.g. when using a 3rd party css-template, and rather prefer to add/remove a class on the element.

The following sample shows a simple way of adding/removing a class on ng-mouseenter/mouseleave:

<div ng-app>
  <div 
    class="italic" 
    ng-class="{red: hover}"
    ng-init="hover = false"
    ng-mouseenter="hover = true"
    ng-mouseleave="hover = false">
      Test 1 2 3.
  </div>
</div>

with some styling:

.red {
  background-color: red;
}

.italic {
  font-style: italic;
  color: black;
}

See running example here: jsfiddle sample

Styling on hovering is a view concern. Although the solution above sets a "hover" property in the current scope, the controller does not need to be concerned about this.

Anti-aliasing cannot be turned on or off, and is controlled by the browser.

Can I turn off antialiasing on an HTML <canvas> element?

"Am i doing it right?Is there better/smarter way to achieve the output this code gave me?"

Generally speaking, yes, you're doing it right. Tkinter has no native scrollable container other than the canvas. As you can see, it's really not that difficult to set up. As your example shows, it only takes 5 or 6 lines of code to make it work -- depending on how you count lines.

"Why must i use grid method?(i tried place method, but none of the labels appear on the canvas?)"

You ask about why you must use grid. There is no requirement to use grid. Place, grid and pack can all be used. It's simply that some are more naturally suited to particular types of problems. In this case it looks like you're creating an actual grid -- rows and columns of labels -- so grid is the natural choice.

"What so special about using anchor='nw' when creating window on canvas?"

The anchor tells you what part of the window is positioned at the coordinates you give. By default, the center of the window will be placed at the coordinate. In the case of your code above, you want the upper left ("northwest") corner to be at the coordinate.

If I understand you correctly, you want to list to exclude duplicates on one column only, inner join to a sub-select

select u.* [whatever joined values]
from users u
inner join
(select name from users group by name having count(*)=1) uniquenames
on uniquenames.name = u.name

I think the following does it semi right. It's been awhile since I've touched C. The idea is to use division since modulus doesn't always give random results. I added 1 to RAND_MAX since there are that many possible values coming from rand including 0. And since the range is also 0 inclusive, I added 1 there too. I think the math is arranged correctly avoid integer math problems.

#define MK_DIVISOR(max) ((int)((unsigned int)RAND_MAX+1/(max+1)))

num = rand()/MK_DIVISOR(65);

Your code is in the default package, i.e. you have source all files in src/main/java with no custom package. I strongly suggest u to create package n then place your source file in it.

Ex-
 src->
     main->
          java->
                com.myfirst.example
                   Example.java
                com.myfirst.example.controller
                   PersonController.java
                com.myfirst.example.repository
                  PersonRepository.java
                com.myfirst.example.model
                   Person.java

I hope it will resolve your problem.

The three best way to do it using a single line of code

import cv2
import numpy as np 


img = cv2.imread('Imgs/Saint_Roch_new/data/Point_4_Face.jpg')
dim = (256, 256)
resizedLena = cv2.resize(img, dim, interpolation = cv2.INTER_LINEAR)
X, Y = resizedLena, resizedLena

# Methode 1: Using Numpy (hstack, vstack)
Fusion_Horizontal = np.hstack((resizedLena, Y, X))
Fusion_Vertical   = np.vstack((newIMG, X))

cv2.imshow('Fusion_Vertical using vstack', Fusion_Vertical)
cv2.waitKey(0)

# Methode 2: Using Numpy (contanate)
Fusion_Vertical   = np.concatenate((resizedLena, X, Y), axis=0)
Fusion_Horizontal = np.concatenate((resizedLena, X, Y), axis=1)

cv2.imshow("Fusion_Horizontal usung concatenate", Fusion_Horizontal)
cv2.waitKey(0)


# Methode 3: Using OpenCV (vconcat, hconcat)
Fusion_Vertical   = cv2.vconcat([resizedLena, X, Y])
Fusion_Horizontal = cv2.hconcat([resizedLena, X, Y])

cv2.imshow("Fusion_Horizontal Using hconcat", Fusion_Horizontal)
cv2.waitKey(0)

I got this error when calling this code: wks.Range[startCell, endCell] where the startCell Range and endCell Range were pointing to different worksheet then the variable wks.

In short: I don't think you can, but there seems to be a workaround:.

If you take a look into the Android Resource here:

http://developer.android.com/guide/topics/resources/string-resource.html

You see than under the array section (string array, at least), the "RESOURCE REFERENCE" (as you get from an XML) does not specify a way to address the individual items. You can even try in your XML to use "@array/yourarrayhere". I know that in design time you will get the first item. But that is of no practical use if you want to use, let's say... the second, of course.

HOWEVER, there is a trick you can do. See here:

Referencing an XML string in an XML Array (Android)

You can "cheat" (not really) the array definition by addressing independent strings INSIDE the definition of the array. For example, in your strings.xml:

<string name="earth">Earth</string>
<string name="moon">Moon</string>

<string-array name="system">
    <item>@string/earth</item>
    <item>@string/moon</item>
</string-array>

By using this, you can use "@string/earth" and "@string/moon" normally in your "android:text" and "android:title" XML fields, and yet you won't lose the ability to use the array definition for whatever purposes you intended in the first place.

Seems to work here on my Eclipse. Why don't you try and tell us if it works? :-)

class Node {
    int data;
    Node left;
    Node right;

    // assign variable with constructor
    public Node(int data) {
        this.data = data;
    }
}

public class BinaryTree {

    Node root;

    // get max depth
    public static int maxDepth(Node node) {
        if (node == null)
            return 0;

        return 1 + Math.max(maxDepth(node.left), maxDepth(node.right));
    }

    // get min depth
    public static int minDepth(Node node) {
        if (node == null)
            return 0;

        return 1 + Math.min(minDepth(node.left), minDepth(node.right));
    }

    // return max-min<=1 to check if tree balanced
    public boolean isBalanced(Node node) {

        if (Math.abs(maxDepth(node) - minDepth(node)) <= 1)
            return true;

        return false;
    }

    public static void main(String... strings) {
        BinaryTree tree = new BinaryTree();
        tree.root = new Node(1);
        tree.root.left = new Node(2);
        tree.root.right = new Node(3);


        if (tree.isBalanced(tree.root))
            System.out.println("Tree is balanced");
        else
            System.out.println("Tree is not balanced");
    }
}

You have to have single quotes around any VARCHAR content in your queries. So your update query should be:

mysql_query("UPDATE blogEntry SET content = '$udcontent', title = '$udtitle' WHERE id = $id");

Also, it is bad form to update your database directly with the content from a POST. You should sanitize your incoming data with the mysql_real_escape_string function.

Some time you have to give all the form element into a same div.

example:-

If you are using ajax submit with modal.

So all the elements are in modal body.

Some time we put submit button in modal footer.

describes and desc command will give list of keyspaces in the cluster.Please find below output for more details.

OR

cqlsh> desc keyspaces
reaper_db      system_auth  system_distributed
system_schema  system       system_traces

Had the same issue, the reason for it was BCrypt.Net library, compiled using .NET 2.0 framework, while the whole project, which used it, was compiling with .NET 4.0. If symptoms are the same, try download BCrypt source code and rebuild it in release configuration within .NET 4.0. After I'd done it "pre-login handshake" worked fine. Hope it helps anyone.

I have used methods described above. Now I am using the method which is a way similiar but more simple to me.

1. First create add README.md file to your project.
2. Then upload screenshoots or whatever description images needed to your project main directory.
3. After uploading image Assets use html to refer these assets directly without using link like below

Like this:

<img src="icon.jpg" width="324" height="324">

<p align="center">
  <img src="screen1.png" width="256" height="455">
  <img src="screen2.png" width="256" height="455">
  <img src="screen3.png" width="256" height="455">
</p>

On above example I have used paragraph to align images side by side. If you are going to use single image just use the code as below

<img src="icon.jpg" width="324" height="324">

Have a nice day!

Requests doesn't have an equivalent to Urlib2's read().

>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True

It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.

Edit for Python 3:

Python now handles data types differently. response.content returns a sequence of bytes (integers that represent ASCII) while response.text is a string (sequence of chars).

Thus,

>>> print response.content == response.text
False

>>> print str(response.content) == response.text
True

Take a look at UrlRewriteFilter which is essentially a java-based implementation of Apache's mod_rewrite.

You'll need to extract it into ROOT folder under your Tomcat's webapps folder; you can then configure redirects to any other context within its WEB-INF/urlrewrite.xml configuration file.

If not using C++14, then I find below the simplest solution.

#define METHOD(NAME, ...) auto NAME __VA_ARGS__ -> decltype(m_T.r##NAME) { return m_T.r##NAME; }
template<typename T>
struct Reverse
{
  T& m_T;

  METHOD(begin());
  METHOD(end());
  METHOD(begin(), const);
  METHOD(end(), const);
};
#undef METHOD

template<typename T>
Reverse<T> MakeReverse (T& t) { return Reverse<T>{t}; }

Demo.
It doesn't work for the containers/data-types (like array), which doesn't have begin/rbegin, end/rend functions.

Luckily, it’s very easy to resolve. Run the follow command from an elevated command prompt:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

If you’re on a 32-bit machine, you may have to use the following:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

I like to do this

input[type="text"]
{
    background: rgba(0, 0, 0, 0);
    border: none;
    outline: none;
}

Setting the outline property to none stops the browser from highlighting the box when the cursor enters

If you are using SQL Server, Use the LEN (Length) function:

SELECT EmployeeName FROM EmployeeTable WHERE LEN(EmployeeName) > 4

MSDN for it states:

Returns the number of characters of the specified string expression,
excluding trailing blanks.

Here's the link to the MSDN

For oracle/plsql you can use Length(), mysql also uses Length.

Here is the Oracle documentation:

http://www.techonthenet.com/oracle/functions/length.php

And here is the mySQL Documentation of Length(string):

http://dev.mysql.com/doc/refman/5.1/en/string-functions.html#function_length

For PostgreSQL, you can use length(string) or char_length(string). Here is the PostgreSQL documentation:

http://www.postgresql.org/docs/current/static/functions-string.html#FUNCTIONS-STRING-SQL

For the first part you can pass a dict of column names for keys and a list of functions for the values:

In [28]: df
Out[28]:
          A         B         C         D         E  GRP
0  0.395670  0.219560  0.600644  0.613445  0.242893    0
1  0.323911  0.464584  0.107215  0.204072  0.927325    0
2  0.321358  0.076037  0.166946  0.439661  0.914612    1
3  0.133466  0.447946  0.014815  0.130781  0.268290    1

In [26]: f = {'A':['sum','mean'], 'B':['prod']}

In [27]: df.groupby('GRP').agg(f)
Out[27]:
            A                   B
          sum      mean      prod
GRP
0    0.719580  0.359790  0.102004
1    0.454824  0.227412  0.034060

UPDATE 1:

Because the aggregate function works on Series, references to the other column names are lost. To get around this, you can reference the full dataframe and index it using the group indices within the lambda function.

Here's a hacky workaround:

In [67]: f = {'A':['sum','mean'], 'B':['prod'], 'D': lambda g: df.loc[g.index].E.sum()}

In [69]: df.groupby('GRP').agg(f)
Out[69]:
            A                   B         D
          sum      mean      prod  <lambda>
GRP
0    0.719580  0.359790  0.102004  1.170219
1    0.454824  0.227412  0.034060  1.182901

Here, the resultant 'D' column is made up of the summed 'E' values.

UPDATE 2:

Here's a method that I think will do everything you ask. First make a custom lambda function. Below, g references the group. When aggregating, g will be a Series. Passing g.index to df.ix[] selects the current group from df. I then test if column C is less than 0.5. The returned boolean series is passed to g[] which selects only those rows meeting the criteria.

In [95]: cust = lambda g: g[df.loc[g.index]['C'] < 0.5].sum()

In [96]: f = {'A':['sum','mean'], 'B':['prod'], 'D': {'my name': cust}}

In [97]: df.groupby('GRP').agg(f)
Out[97]:
            A                   B         D
          sum      mean      prod   my name
GRP
0    0.719580  0.359790  0.102004  0.204072
1    0.454824  0.227412  0.034060  0.570441

Originally posted as an edit to @0x90's answer, but it got rejected for deviating from the post's original intent and recommended to post as a comment or answer, so I'm including the short write-up here.

In addition to the answer from @0x90, the syntax can be made more flexible, by using a variable for the width (as per @user2763554's comment):

width=10
'{0: <{width}}'.format('sss', width=width)

Further, you can make this expression briefer, by only using numbers and relying on the order of the arguments passed to format:

width=10
'{0: <{1}}'.format('sss', width)

Or even leave out all numbers for maximal, potentially non-pythonically implicit, compactness:

width=10
'{: <{}}'.format('sss', width)

Update 2017-05-26

With the introduction of formatted string literals ("f-strings" for short) in Python 3.6, it is now possible to access previously defined variables with a briefer syntax:

>>> name = "Fred"
>>> f"He said his name is {name}."
'He said his name is Fred.'

This also applies to string formatting

>>> width=10
>>> string = 'sss'
>>> f'{string: <{width}}'
'sss       '

It is clear that tvi.header is not a String. The == is an operator that is overloaded by String class, which means it will be working only if compiler knows that both side of the operator are String.

Just adding to this that in ES6 because of arrow functions you shouldn't need to do this because they capture the this value.

To mark a lambda async, simply prepend async before its argument list:

// Add a command to delete the current Group
contextMenu.Commands.Add(new UICommand("Delete this Group", async (contextMenuCmd) =>
{
    SQLiteUtils slu = new SQLiteUtils();
    await slu.DeleteGroupAsync(groupName);
}));

Inline:

<select 
onchange="var val = this.options[this.selectedIndex].value;
this.form.color[1].style.display=(val=='others')?'block':'none'">

I used to do this

In the head (give the select an ID):

window.onload=function() {
  var sel = document.getElementById('color');
  sel.onchange=function() {
    var val = this.options[this.selectedIndex].value;
    if (val == 'others') {
      var newOption = prompt('Your own color','');
      if (newOption) {
        this.options[this.options.length-1].text = newOption;
        this.options[this.options.length-1].value = newOption;
        this.options[this.options.length] = new Option('other','other');
      }
    }
  }
}

Here's some code that may help:

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

string serial_number="";

foreach (ManagementObject wmi_HD in searcher.Get())
{
    serial_number = wmi_HD["SerialNumber"].ToString();
}

MessageBox.Show(serial_number);

If you really need to modify the original dictionary:

empty_keys = [k for k,v in metadata.iteritems() if not v]
for k in empty_keys:
    del metadata[k]

Note that we have to make a list of the empty keys because we can't modify a dictionary while iterating through it (as you may have noticed). This is less expensive (memory-wise) than creating a brand-new dictionary, though, unless there are a lot of entries with empty values.

Create Globals class in app/globals.ts:

import { Injectable } from '@angular/core';

Injectable()
export class Globals{
    VAR1 = 'value1';
    VAR2 = 'value2';
}

In your component:

import { Globals } from './globals';

@Component({
    selector: 'my-app',
    providers: [ Globals ],
    template: `<h1>My Component {{globals.VAR1}}<h1/>`
})
export class AppComponent {
    constructor(private globals: Globals){
    }
}

Note: You can add Globals service provider directly to the module instead of the component, and you will not need to add as a provider to every component in that module.

@NgModule({
    imports: [...],
    declarations: [...],
    providers: [ Globals ],
    bootstrap: [ AppComponent ]
})
export class AppModule {
}

Check the Variables section in the Go template docs. A range may declare two variables, separated by a comma. The following should work:

{{ range $key, $value := . }}
   <li><strong>{{ $key }}</strong>: {{ $value }}</li>
{{ end }}

SELECT id FROM tbl GROUP BY cat HAVING MAX(date)

The HTTP/1.1 spec (section 9.6) discusses the appropriate response/error codes. However it doesn't address the response content.

What would you expect ? A simple HTTP response code (200 etc.) seems straightforward and unambiguous to me.

This seems to be a little buggy in Pandas 0.23.4?

If there are np.nan values then this will throw an error as expected:

df['col'] = df['col'].astype(np.int64)

But doesn't change any values from float to int as I would expect if "ignore" is used:

df['col'] = df['col'].astype(np.int64,errors='ignore') 

It worked if I first converted np.nan:

df['col'] = df['col'].fillna(0).astype(np.int64)
df['col'] = df['col'].astype(np.int64)

Now I can't figure out how to get null values back in place of the zeroes since this will convert everything back to float again:

df['col']  = df['col'].replace(0,np.nan)

There is a simpler solution to this. What you describe is the natural behavior of the & operator and can thus be done primatively:

> c(1,1,NA) & c(1,0,NA) & c(1,NA,NA)
[1]  TRUE FALSE    NA

If all are 1, then 1 is returned. If any are 0, then 0. If all are NA, then NA.

In your case, the code would be:

DF$Den<-DF$Denial1 & DF$Denial2 & DF$Denial3

In order for this to work, you will need to stop working in character and use numeric or logical types.

Dim sHostName As String

' Get Host Name / Get Computer Name

sHostName = Environ$("computername")

To retrieve your image from byte to base64 string....

Model property:

    public byte[] NomineePhoto { get; set; }

    public string NomineePhoneInBase64Str 
    {
        get {
            if (NomineePhoto == null)
                return "";

            return $"data:image/png;base64,{Convert.ToBase64String(NomineePhoto)}";
        } 
    }

IN view:

   <img style="height:50px;width:50px" src="@item.NomineePhoneInBase64Str" />

There is a dirty trick, what I have used:

I am using bootstrap, so I just added .disabled class to the element which I want to disable. Bootstrap handles the rest of the things.

Suggestion are heartily welcome towards this.

Adding class on run time:

$('#element').addClass('disabled');

For those looking for a solution from an Angular perspective, this worked for me:

$http.post(
  'url',
  {},
  {responseType: 'arraybuffer'}
).then(function (response) {
  var headers = response.headers();
  var blob = new Blob([response.data],{type:headers['content-type']});
  var link = document.createElement('a');
  link.href = window.URL.createObjectURL(blob);
  link.download = "Filename";
  link.click();
});

Based on the Microsoft support KBs, this can occur if TCP/IP is damaged or is not bound to your dial-up adapter.You can try reinstalling or resetting TCP/IP as follows:

• Reset TCP/IP to Original Configuration- Using the NetShell utility, type this command (in CommandLine): netsh int ip reset [file_name.txt], [file_name.txt] is the name of the file where the actions taken by NetShell are record, for example netsh hint ip reset fixtcpip.txt.

• Remove and re-install NIC – Open Controller and select System. Click Hardware tab and select devices. Double-click on Network Adapter and right-click on the NIC, select Uninstall. Restart the computer and the Windows should auto detect the NIC and re-install it.

• Upgrade the NIC driver – You may download the latest NIC driver and upgrade the driver.

Hope it could help.

I am not aware of any libraries to do this (but I am sure there are many that can) but if you can already create HTML from the crystal report why not use XSLT to clean up the markup?

Thanks to David as his solution helped me come up with my solution for uploading multi-part files from my Heroku hosted site to S3 bucket. I did it using formidable to handle incoming form and fs to get the file content. Hopefully, it may help you.

api.service.ts

public upload(files): Observable<any> {  
    const formData: FormData = new FormData(); 
    files.forEach(file => {
      // create a new multipart-form for every file 
      formData.append('file', file, file.name);           
    });   
    return this.http.post(uploadUrl, formData).pipe(
      map(this.extractData),
      catchError(this.handleError)); 
  }
}

server.js

app.post('/api/upload', upload);
app.use('/api/upload', router);

const IncomingForm = require('formidable').IncomingForm;
const fs = require('fs');
const AWS = require('aws-sdk');

module.exports = function upload(req, res) {
    var form = new IncomingForm();

    const bucket = new AWS.S3(
      {
        signatureVersion: 'v4',
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
        region: 'us-east-1'       
      }
    ); 

    form.on('file', (field, file) => {

        const fileContent = fs.readFileSync(file.path);

        const s3Params = {
            Bucket: process.env.AWS_S3_BUCKET,
            Key: 'folder/' + file.name,
            Expires: 60,             
            Body: fileContent,
            ACL: 'public-read'
        };

        bucket.upload(s3Params, function(err, data) {

          });
        });
    });              

    // The second callback is called when the form is completely parsed. 
    // In this case, we want to send back a success status code.
    form.on('end', () => {        
      res.status(200).json('upload ok');
    });

    form.parse(req);
}

You can use this simple plugin to add scrollUp and scrollDown to your jQuery

https://github.com/phpust/JQueryScrollDetector

var lastScrollTop = 0;
var action = "stopped";
var timeout = 100;
// Scroll end detector:
$.fn.scrollEnd = function(callback, timeout) {    
      $(this).scroll(function(){
        // get current scroll top 
        var st = $(this).scrollTop();
        var $this = $(this);
        // fix for page loads
        if (lastScrollTop !=0 )
        {
            // if it's scroll up
            if (st < lastScrollTop){
                action = "scrollUp";
            } 
            // else if it's scroll down
            else if (st > lastScrollTop){
                action = "scrollDown";
            }
        }
        // set the current scroll as last scroll top
        lastScrollTop = st;
        // check if scrollTimeout is set then clear it
        if ($this.data('scrollTimeout')) {
          clearTimeout($this.data('scrollTimeout'));
        }
        // wait until timeout done to overwrite scrolls output
        $this.data('scrollTimeout', setTimeout(callback,timeout));
    });
};

$(window).scrollEnd(function(){
    if(action!="stopped"){
        //call the event listener attached to obj.
        $(document).trigger(action); 
    }
}, timeout);

Unfortunately that approach is not portable C++ (so far).

All standard names are in namespace std and moreover you cannot know which names are NOT defined by including and header (in other words it's perfectly legal for an implementation to declare the name std::string directly or indirectly when using #include <vector>).

Despite this however you are required by the language to know and tell the compiler which standard header includes which part of the standard library. This is a source of portability bugs because if you forget for example #include <map> but use std::map it's possible that the program compiles anyway silently and without warnings on a specific version of a specific compiler, and you may get errors only later when porting to another compiler or version.

In my opinion there are no valid technical excuses because this is necessary for the general user: the compiler binary could have all standard namespace built in and this could actually increase the performance even more than precompiled headers (e.g. using perfect hashing for lookups, removing standard headers parsing or loading/demarshalling and so on).

The use of standard headers simplifies the life of who builds compilers or standard libraries and that's all. It's not something to help users.

However this is the way the language is defined and you need to know which header defines which names so plan for some extra neurons to be burnt in pointless configurations to remember that (or try to find and IDE that automatically adds the standard headers you use and removes the ones you don't... a reasonable alternative).

The best - and simplest - solution might be this:

Intent intent = new Intent(this, OtherActivity.class);
startActivity(intent);
finishAndRemoveTask();

Documentation for finishAndRemoveTask():

Call this when your activity is done and should be closed and the task should be completely removed as a part of finishing the root activity of the task.

Is that what you're looking for?

you can do like this @item.Date.Value.Tostring("dd-MMM-yy");

Try something like this to convert JToken to JArray:

static public JArray convertToJArray(JToken obj)
{
    // if ((obj).Type == JTokenType.Null) --> You can check if it's null here

    if ((obj).Type == JTokenType.Array)
        return (JArray)(obj);
    else
        return new JArray(); // this will return an empty JArray
}

for windows, using java.io this reccursive function is useful.

    public static long folderSize(File directory) {
    long length = 0;

    if (directory.isFile())
         length += directory.length();
    else{
        for (File file : directory.listFiles()) {
             if (file.isFile())
                 length += file.length();
             else
                 length += folderSize(file);
        }
    }

    return length;
}

This is tested and working properly on my end.

numbers = [1, 2, 3]
numsum = sum(list(numbers))
print(numsum)

This would work, if your are trying to Sum up a list.

One possible PHP solution:

// load XML to SimpleXML
$x = simplexml_load_string($xmlstr);

// index it by title once
$index = array();
foreach ($x->CD as &$cd) {
  $title = strtolower((string)$cd['title']); 
  if (!array_key_exists($title, $index)) $index[$title] = array();
  $index[$title][] = &$cd;
}

// query the index 
$result = $index[strtolower("EMPIRE BURLESQUE")];

addedMonth <- seq(as.Date('2004-01-01'), length=2, by='1 month')[2]
addedQuarter <- seq(as.Date('2004-01-01'), length=2, by='1 quarter')[2]

There are more than that. The executed executables are different.

npm run start

will run your projects local executable which is located in your node_modules/.bin.

ng serve

will run another executable which is global.

It means if you clone and install an Angular project which is created with angular-cli version 5 and your global cli version is 7, then you may have problems with ng build.

this.$router.go(this.$router.currentRoute)

Vue-Router Docs:

I checked vue-router repo on GitHub and it seems that there isn't reload() method any more. But in the same file, there is: currentRoute object.

Source: vue-router/src/index.js
Docs: docs

get currentRoute (): ?Route {
    return this.history && this.history.current
  }

Now you can use this.$router.go(this.$router.currentRoute) for reload current route.

Simple example.

Version for this answer:

"vue": "^2.1.0",
"vue-router": "^2.1.1"

Jquery:

var afterDot = value.substr(value.lastIndexOf('_') + 1);

Javascript:

var myString = 'asd/f/df/xc/asd/test.jpg'
var parts    = myString.split('/');
var answer   = parts[parts.length - 1];
console.log(answer);

Replace '_' || '/' to your own need

If you want the key and value when iterating, you can use a for...of loop with Object.entries.

const myObj = {a: 1, b: 2}

for (let [key, value] of Object.entries(myObj)) {
    console.log(`key=${key} value=${value}`)
}

// output: 
// key=a value=1
// key=b value=2

Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.

ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.

The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).

A better option

Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses (and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.

A quick google search yields kludgey solutions such as this that use setjmp/longjmp as others have mentioned. Nothing as straightforward and elegant as C++/Java's try/catch. I'm rather partial to Ada's exception handling myself.

Check everything with if statements :)

480 dpi is the standard QUANTIZED resolution for xxhdpi, it can vary something less (i.e.: 440 dpi) or more (i.e.: 520 dpi). Scale factor: 3x (3 * mdpi).

Now there's a higher resolution, xxxhdpi (640 dpi). Scale factor 4x (4 * mdpi).

Here's the source reference.

one more suggestion :

unsigned int a = 0xABCDEF23;
a = ((a&(0x0000FFFF)) << 16) | ((a&(0xFFFF0000)) >> 16);
a = ((a&(0x00FF00FF)) << 8) | ((a&(0xFF00FF00)) >>8);
printf("%0x\n",a);

            $string = mb_convert_encoding($string, 'ISO-8859-1', 'UTF-8');

You can set it as a no title bar theme in the activity's xml in the AndroidManifest

Check the character set of both projects in Configuration Properties ? General ? Character Set.

My UnitTest project was using the default character set Multi-Byte while my libraries were in Unicode.

My function was using a TCHAR as a parameter.

As a result, in my library my TCHAR was transformed into a WCHAR, but it was a char* in my UnitTest: the symbol was different because the parameters were really not the same in the end.

use android-28 with build-tools at version 28.0.3; or build-tools at version 26.0.3.

or try this: yes | sudo sdkmanager --licenses

In the original example, why not use the select() method in your database query?

$name = DB::table('users')->where('name', 'John')->select("id");

This will be faster than using a PHP framework, for it'll utilize the SQL query to do the row selection for you. For ordinary collections, I don't believe this applies, but since you're using a database...

Larvel 5.3: Specifying a Select Clause

I would do something like:

filename = "mynumbers.txt"
mynumbers = []
with open(filename) as f:
    for line in f:
        mynumbers.append([int(n) for n in line.strip().split(',')])
for pair in mynumbers:
    try:
        x,y = pair[0],pair[1]
        # Do Something with x and y
    except IndexError:
        print "A line in the file doesn't have enough entries."

The with open is recommended in http://docs.python.org/tutorial/inputoutput.html since it makes sure files are closed correctly even if an exception is raised during the processing.

This problem can be caused by undue manipulation of the enabled cipher suites at the client or the server, but I suspect the most common cause is the server not having a private key and certificate at all.

NB:

ssl.setEnabledCipherSuites(sc.getServerSocketFactory().getSupportedCipherSuites());

Get rid of this line. Your server is insecure enough already with that insecure TrustManager. Then run your server with -Djavax.net.debug=SSL,handshake, try one connect, and post the resulting output here.

obligatory: "use jQuery"

I've seen pages that put a black or white div that covers everything on top of the page, then remove it on the document.load event. Or you could use .ready in jQuery That being said, it was one of the most anoying web pages I've ever seen, I would advise against it.

Use the global flag:

var name = name.replace(/[^a-zA-Z ]/g, "");
                                    ^

If you don't want to remove numbers, add it to the class:

var name = name.replace(/[^a-zA-Z0-9 ]/g, "");

Adding more to Andreas' answer. I had the same problem with ES6 code, but I did not want to mutate the imports. That looked hacky. So I did this:

import myModule from '../myModule';
import dependency from '../dependency';
jest.mock('../dependency');

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    myModule(2);
  });
});

And added file dependency.js in the " __ mocks __" folder parallel to file dependency.js. This worked for me. Also, this gave me the option to return suitable data from the mock implementation. Make sure you give the correct path to the module you want to mock.

For SQL Server 2008 users, I made a custom function:

CREATE FUNCTION sql2012_datefromparts
(   
    @Year int, @Month int, @Day int
)
RETURNS DATETIME
AS
BEGIN
    RETURN convert(datetime,convert(varchar,@year)+right('0'+convert(varchar,@month),2)+right('0'+convert(varchar,@day),2)) 
END
GO

To use it:

DECLARE @day int=29, @month int=10, @year int=1971
SELECT dbo.sql2012_datefromparts(@year,@month,@day)

I just downloaded Git 2.7.0 and added an alias to the .bashrc for editing files with VS Code:

alias code='/c/Program\ Files\ \(x86\)/Microsoft\ VS\ Code/bin/code.cmd'

Should also work with other Editors...

In your ajax success callback do this:

success: function(data){
   if(data.success == true){ // if true (1)
      setTimeout(function(){// wait for 5 secs(2)
           location.reload(); // then reload the page.(3)
      }, 5000); 
   }
}

As you want to reload the page after 5 seconds, then you need to have a timeout as suggested in the answer.

parser.add_argument also has a switch required. You can use required=False. Here is a sample snippet with Python 2.7:

parser = argparse.ArgumentParser(description='get dir')
parser.add_argument('--dir', type=str, help='dir', default=os.getcwd(), required=False)
args = parser.parse_args()

I had this error in Windows 10. I followed these three steps and it solved my problem:

1. Install nbconvert

   pip install nbconvert

2. Install pandoc

https://pandoc.org/installing.html

3. Install miktex

https://miktex.org/download

Also it is good to update libraries:

pip install jupyter --upgrade
pip install --upgrade --user nbconvert

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

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

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

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

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

This works everywhere including Safari 5 and Firefox 5 on OS X.

UPDATE: Fx Quantum (54) has no need for the replace, but Safari 11 is still not happy unless you convert as below

var date_test = new Date("2011-07-14 11:23:00".replace(/-/g,"/"));_x000D_
console.log(date_test);

FIDDLE

I got this sort of message when I had two files that depended on each other. The tricky thing here is that you'll get a circular reference if you just try to import each other (class A imports class B, class B imports class A) from their header files. So what you would do is instead place a forward (@class A) declaration in one of the classes' (class B's) header file. However, when attempting to use an ivar of class A within the implementation of class B, this very error comes up, merely adding an #import "A.h" in the .m file of class B fixed the problem for me.

Look at the ASCII table here and you'll see that 39 (hex 0x27, octal 47) is the code for apostrophe

I think that you should use a connection pool instead of share a single connection. A connection pool would provide a much better performance, as you can check here.

As stated in the library documentation, it occurs because the MySQL protocol is sequential (this means that you need multiple connections to execute queries in parallel).

Connection Pool Docs

var start = new Date();
start.setHours(0,0,0,0);

var end = new Date();
end.setHours(23,59,59,999);

alert( start.toUTCString() + ':' + end.toUTCString() );

If you need to get the UTC time from those, you can use UTC().

As ant31 already pointed out you can use the synchronize module to this. By default, the module transfers files between the control machine and the current remote host (inventory_host), however that can be changed using the task's delegate_to parameter (it's important to note that this is a parameter of the task, not of the module).

You can place the task on either ServerA or ServerB, but you have to adjust the direction of the transfer accordingly (using the mode parameter of synchronize).

Placing the task on ServerB

- hosts: ServerB
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
      delegate_to: ServerA

This uses the default mode: push, so the file gets transferred from the delegate (ServerA) to the current remote (ServerB).

This might sound like strange, since the task has been placed on ServerB (via hosts: ServerB). However, one has to keep in mind that the task is actually executed on the delegated host, which in this case is ServerA. So pushing (from ServerA to ServerB) is indeed the correct direction. Also remember that we cannot simply choose not to delegate at all, since that would mean that the transfer happens between the control machine and ServerB.

Placing the task on ServerA

- hosts: ServerA
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
        mode: pull
      delegate_to: ServerB

This uses mode: pull to invert the transfer direction. Again, keep in mind that the task is actually executed on ServerB, so pulling is the right choice.

I add this answer because I think it could be useful to anybody.

I step into the problem of setting RGBA colors (that is, RGB color with an Alpha value for transparency) for color display labels in my painting application.

As I came across the first answer, I was unable to set an RGBA color. I have also tried things like:

myLabel.setStyleSheet("QLabel { background-color : %s"%color.name())

where color is an RGBA color.

So, my dirty solution was to extend QLabel and override paintEvent() method filling its bounding rect.

Today, I've open up the qt-assistant and read the style reference properties list. Affortunately, it has an example that states the following:

QLineEdit { background-color: rgb(255, 0, 0) }

Thats open up my mind in doing something like the code below, as an example:

myLabel= QLabel()
myLabel.setAutoFillBackground(True) # This is important!!
color  = QtGui.QColor(233, 10, 150)
alpha  = 140
values = "{r}, {g}, {b}, {a}".format(r = color.red(),
                                     g = color.green(),
                                     b = color.blue(),
                                     a = alpha
                                     )
myLabel.setStyleSheet("QLabel { background-color: rgba("+values+"); }")

Note that setAutoFillBackground() set in False will not make it work.

Regards,

I don't have a unix system under my hands, but try this:

count7=$((${count7} + ${count1}))

Or maybe you have a shell that doesn't support this expression. I think bash does support it, but sh doesn't.

EDIT: There is another syntax, try:

count7=`expr $count7 + $count1`

To convert utf-8 data, you can't assume a 1-1 correspondence between bytes and characters. Try this:

String file_string = new String(bytes, "UTF-8");

(Bah. I see I'm way to slow in hitting the Post Your Answer button.)

To read an entire file as a String, do something like this:

public String openFileToString(String fileName) throws IOException
{
    InputStream is = new BufferedInputStream(new FileInputStream(fileName));

    try {
        InputStreamReader rdr = new InputStreamReader(is, "UTF-8");
        StringBuilder contents = new StringBuilder();
        char[] buff = new char[4096];
        int len = rdr.read(buff);
        while (len >= 0) {
            contents.append(buff, 0, len);
        }
        return buff.toString();
    } finally {
        try {
            is.close();
        } catch (Exception e) {
            // log error in closing the file
        }
    }
}

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.google.com");
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

string strResponse = reader.ReadToEnd();

3. Restart MAMP servers.

Use ../:

background-image: url('../images/bg.png');

You can use that as often as you want, e.g. ../../images/ or even at different positions, e.g. ../images/../images/../images/ (same as ../images/ of course)

For me the problem was invalid permissions - I was requesting "birthday" instead of "user_birthday". It's a shame the error message isn't at least minimally descriptive - just saying "permissions invalid" rather than ERROR CODE 2 would have saved me so much time.

To configure your JRE in eclipse:

• Window > Preferences > Java > Installed JREs...

This is from my xamarin.forms code, the class derives from NavigationRenderer

NavigationBar.Items.FirstOrDefault().BackBarButtonItem = new UIBarButtonItem( "", UIBarButtonItemStyle.Plain, null);

You can directly access a global variable inside a function. If you want to change the value of that global variable, use "global variable_name". See the following example:

var = 1
def global_var_change():
      global var
      var = "value changed"
global_var_change() #call the function for changes
print var

Generally speaking, this is not a good programming practice. By breaking namespace logic, code can become difficult to understand and debug.

Use document.location.href to change the page location, place it in the function on a successful ajax run.

For T-SQL (MSSQL 2008+)

SELECT
  (SELECT
     MAX(MyMaxName) 
   FROM ( VALUES 
            (MAX(Field1)), 
            (MAX(Field2)) 
        ) MyAlias(MyMaxName)
  ) 
FROM MyTable1

This is what I did. Most tooltip scripts require you to execute a function that stores the tooltips. This is a jQuery example:

$.when($('*').filter(function() {
   return $(this).css('text-overflow') == 'ellipsis';
}).each(function() {
   if (this.offsetWidth < this.scrollWidth && !$(this).attr('title')) {
      $(this).attr('title', $(this).text());
   }
})).done(function(){ 
   setupTooltip();
});

If you didn't want to check for ellipsis css, you could simplify like:

$.when($('*').filter(function() {
   return (this.offsetWidth < this.scrollWidth && !$(this).attr('title'));
}).each(function() {
   $(this).attr('title', $(this).text());
})).done(function(){ 
   setupTooltip();
});

I have the "when" around it, so that the "setupTooltip" function doesn't execute until all titles have been updated. Replace the "setupTooltip", with your tooltip function and the * with the elements you want to check. * will go through them all if you leave it.

If you simply want to just update the title attributes with the browsers tooltip, you can simplify like:

$('*').filter(function() {
   return $(this).css('text-overflow') == 'ellipsis';
}).each(function() {
   if (this.offsetWidth < this.scrollWidth && !$(this).attr('title')) {
      $(this).attr('title', $(this).text());
   }
});

Or without check for ellipsis:

$.when($('*').filter(function() {
   return (this.offsetWidth < this.scrollWidth && !$(this).attr('title'));
}).each(function() {
   $(this).attr('title', $(this).text());
});

note you can only do this with Numbers and Strings

you could do...

var a, b, c; a = b = c = 0; //but why?

c++;
// c = 1, b = 0, a = 0;

For O(1) complexity of head,tail operation you should use deque however.

Following way:

from collections import deque
l = deque([1,2,3,4,5,6,7,8,9])
head, tail = l.popleft(), l

It's useful when you must iterate through all elements of the list. For example in naive merging 2 partitions in merge sort.

As of now (studio 0.61) maintaining proper project structure is enough. No need to create separate test project as in eclipse (see below).

JToken is the base class for JObject, JArray, JProperty, JValue, etc. You can use the Children<T>() method to get a filtered list of a JToken's children that are of a certain type, for example JObject. Each JObject has a collection of JProperty objects, which can be accessed via the Properties() method. For each JProperty, you can get its Name. (Of course you can also get the Value if desired, which is another JToken.)

Putting it all together we have:

JArray array = JArray.Parse(json);

foreach (JObject content in array.Children<JObject>())
{
    foreach (JProperty prop in content.Properties())
    {
        Console.WriteLine(prop.Name);
    }
}

Output:

MobileSiteContent
PageContent

<?php
    $array = array("your array");
    $array = array_diff($array, ["element you want to delete"]);
?>

Create your array in the variable $array and then where I have put 'element you want to delete' you put something like: "a". And if you want to delete multiple items then: "a", "b".

I have the same issue and solved it by reading this post, while solving it, I hitted a problem: auth failed.

And I finally solved it by using a ssh key way to authorize myself. I found the EGit offical guide very useful and I configured the ssh way successfully by refer to the Eclipse SSH Configuration section in the link provided.

Hope it helps.

If you still can not unmount or remount your device after stopping all services and processes with open files, then there may be a swap file or swap partition keeping your device busy. This will not show up with fuser or lsof. Turn off swapping with:

sudo swapoff -a

You could check beforehand and show a summary of any swap partitions or swap files with:

swapon -s

or:

cat /proc/swaps

As an alternative to using the command sudo swapoff -a, you might also be able to disable the swap by stopping a service or systemd unit. For example:

sudo systemctl stop dphys-swapfile

or:

sudo systemctl stop var-swap.swap

In my case, turning off swap was necessary, in addition to stopping any services and processes with files open for writing, so that I could remount my root partition as read only in order to run fsck on my root partition without rebooting. This was necessary on a Raspberry Pi running Raspbian Jessie.

See JavaDoc of java.lang.Object

In hashCode() it says:

If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.

(Emphasis by me).

If you only override equals() and not hashCode() your class violates this contract.

This is also said in the JavaDoc of the equals() method:

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Don't use @@ERROR, use BEGIN TRY/BEGIN CATCH instead. See this article: Exception handling and nested transactions for a sample procedure:

create procedure [usp_my_procedure_name]

    set nocount on;
    declare @trancount int;
    set @trancount = @@trancount;
    begin try
        if @trancount = 0
            begin transaction
        else
            save transaction usp_my_procedure_name;

It has been asked in the past, apparently it costs a lot to mobile browsers, so it's been disabled.

Check this comment by @PaulIrish:

Fixed-backgrounds have huge repaint cost and decimate scrolling performance, which is, I believe, why it was disabled.

I had the same issue. I solved it by using the following steps(Editor: IntelliJ):

1. View -> Tool Windows -> Maven Project. Opens your projects in a sub-window.
2. Click on the arrow next to your project.
3. Click on the lifecycle.
4. Click on clean.

My solution expands on @tak3r's.

It returns an empty object when there are no query parameters and supports the array notation ?a=1&a=2&a=3:

function getQueryParams () {
  function identity (e) { return e; }
  function toKeyValue (params, param) {
    var keyValue = param.split('=');
    var key = keyValue[0], value = keyValue[1];

    params[key] = params[key]?[value].concat(params[key]):value;
    return params;
  }
  return decodeURIComponent(window.location.search).
    replace(/^\?/, '').split('&').
    filter(identity).
    reduce(toKeyValue, {});
}

JSONArray has a constructor which takes a String source (presumed to be an array).

So something like this

JSONArray array = new JSONArray(yourJSONArrayAsString);

Another possible cause for this error message is if the HTTP Method is blocked by the server or load balancer.

It seems to be standard security practice to block unused HTTP Methods. We ran into this because HEAD was being blocked by the load balancer (but, oddly, not all of the load balanced servers, which caused it to fail only some of the time). I was able to test that the request itself worked fine by temporarily changing it to use the GET method.

The error code on iOS was: Error requesting App Code: Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

• float stores floating-point values, that is, values that have potential decimal places
• int only stores integral values, that is, whole numbers

So while both are 32 bits wide, their use (and representation) is quite different. You cannot store 3.141 in an integer, but you can in a float.

Dissecting them both a little further:

In an integer, all bits are used to store the number value. This is (in Java and many computers too) done in the so-called two's complement. This basically means that you can represent the values of −2³¹ to 2³¹ − 1.

In a float, those 32 bits are divided between three distinct parts: The sign bit, the exponent and the mantissa. They are laid out as follows:

S EEEEEEEE MMMMMMMMMMMMMMMMMMMMMMM

There is a single bit that determines whether the number is negative or non-negative (zero is neither positive nor negative, but has the sign bit set to zero). Then there are eight bits of an exponent and 23 bits of mantissa. To get a useful number from that, (roughly) the following calculation is performed:

M × 2^E

(There is more to it, but this should suffice for the purpose of this discussion)

The mantissa is in essence not much more than a 24-bit integer number. This gets multiplied by 2 to the power of the exponent part, which, roughly, is a number between −128 and 127.

Therefore you can accurately represent all numbers that would fit in a 24-bit integer but the numeric range is also much greater as larger exponents allow for larger values. For example, the maximum value for a float is around 3.4 × 10³⁸ whereas int only allows values up to 2.1 × 10⁹.

But that also means, since 32 bits only have 4.2 × 10⁹ different states (which are all used to represent the values int can store), that at the larger end of float's numeric range the numbers are spaced wider apart (since there cannot be more unique float numbers than there are unique int numbers). You cannot represent some numbers exactly, then. For example, the number 2 × 10¹² has a representation in float of 1,999,999,991,808. That might be close to 2,000,000,000,000 but it's not exact. Likewise, adding 1 to that number does not change it because 1 is too small to make a difference in the larger scales float is using there.

Similarly, you can also represent very small numbers (between 0 and 1) in a float but regardless of whether the numbers are very large or very small, float only has a precision of around 6 or 7 decimal digits. If you have large numbers those digits are at the start of the number (e.g. 4.51534 × 10³⁵, which is nothing more than 451534 follows by 30 zeroes – and float cannot tell anything useful about whether those 30 digits are actually zeroes or something else), for very small numbers (e.g. 3.14159 × 10⁻²⁷) they are at the far end of the number, way beyond the starting digits of 0.0000...

Reading and writing from and to a file can be blocked by your OS depending on the file's permission attributes.

If you are trying to read from the file, then I recommend using File's setReadable method to set it to true, or, this code for instance:

String arbitrary_path = "C:/Users/Username/Blah.txt";
byte[] data_of_file;
File f = new File(arbitrary_path);
f.setReadable(true);
data_of_file = Files.readAllBytes(f);
f.setReadable(false); // do this if you want to prevent un-knowledgeable 
                      //programmers from accessing your file.

If you are trying to write to the file, then I recommend using File's setWritable method to set it to true, or, this code for instance:

String arbitrary_path = "C:/Users/Username/Blah.txt";
byte[] data_of_file = { (byte) 0x00, (byte) 0xFF, (byte) 0xEE };
File f = new File(arbitrary_path);
f.setWritable(true);
Files.write(f, byte_array);
f.setWritable(false); // do this if you want to prevent un-knowledgeable 
                      //programmers from changing your file (for security.)

Looking at the code always helps too. That is, you can actually take a look at the generated partial class (that calls LoadComponent) by doing the following:

1. Go to the Solution Explorer pane in the Visual Studio solution that you are interested in.
2. There is a button in the tool bar of the Solution Explorer titled 'Show All Files'. Toggle that button.
3. Now, expand the obj folder and then the Debug or Release folder (or whatever configuration you are building) and you will see a file titled YourClass.g.cs.

The YourClass.g.cs ... is the code for generated partial class. Again, if you open that up you can see the InitializeComponent method and how it calls LoadComponent ... and much more.

I think the best way, is to use a Propper Form and to use jQuery.serializeArray.

<!-- a form with any type of input -->
<form class="a-form">
    <select name="field[something]">...</select>
    <input type="checkbox" name="field[somethingelse]" ... />
    <input type="radio" name="field[somethingelse2]" ... />
    <input type="text" name="field[somethingelse3]" ... />
</form>

<!-- sample ajax call -->
<script>
$(document).ready(function(){
    $.ajax({
        url: 'submit.php',
        type: 'post',
        data: $('form.a-form').serializeArray(),
        success: function(response){
            ...
        }
    });
});
</script>

The Values will be available in PHP as $_POST['field'][INDEX].

Remove the dot and import absolute_import in the beginning of your file

from __future__ import absolute_import

from p_02_paying_debt_off_in_a_year import compute_balance_after

You can convert to a Set and back to an Array again quite easily:

let unique = Array(Set(originals))

This is not guaranteed to maintain the original order of the array.

Just use Kotlin!

val list = listOf(user1, user2, user3)
val maxDate = list.maxBy { it.date }?.date

I have found that creating a var to hold the WebElement and the call the sendKeys() works for me.

WebElement speedCurrentCell = driver.findElement(By.id("Speed_current"));
speedCurrentCell.sendKeys("1300");

step 1.Go to https://dev.twitter.com/apps

step 2.Create app(fill up the form)

step 3.Change permissions if necessary(depending if you want to just read,write or execute)

step 4.Go To API keys section and click generate ACCESS TOKEN.

5 years late to answer :)

Now you have these tokens which is all you need.

'oauth_access_token' => Access token
'oauth_access_token_secret' => Access token secret
'consumer_key' => API key
'consumer_secret' => API secret

Make outer <div> to position: relative and inner <div> to position: absolute. It should work for you.

misread the question, corrected. Try:

var myNumber = 100,
    myarr = (function arr(i){return i ? arr(i-1).concat(i) : [i]}(myNumber));

Just for fun, if you extend Array like this:

Array.prototype.mapx = function(callback){
  return String(this).split(',').map(callback);
}

You could use:

var myNum = 100, 
    myarr = new Array(myNum).mapx(function(el,i){return i+1;});

You might just have to install the packages.

yum install php-pdo php-mysqli

After they're installed, restart Apache.

httpd restart

or

apachectl restart

This is how I organized my application's static resources.

Verilog thinks in bits, so reg [7:0] a[0:3] will give you a 4x8 bit array (=4x1 byte array). You get the first byte out of this with a[0]. The third bit of the 2nd byte is a[1][2].

For a 2D array of bytes, first check your simulator/compiler. Older versions (pre '01, I believe) won't support this. Then reg [7:0] a [0:3] [0:3] will give you a 2D array of bytes. A single bit can be accessed with a[2][0][7] for example.

reg [7:0] a [0:3];
reg [7:0] b [0:3] [0:3];

reg [7:0] c;
reg d;

initial begin

   for (int i=0; i<=3; i++) begin
      a[i] = i[7:0];
   end

   c = a[0];
   d = a[1][2]; 


   // using 2D
   for (int i=0; i<=3; i++)
      for (int j=0; j<=3; j++)
          b[i][j] = i*j;  // watch this if you're building hardware

end

By 'JSON array containing objects' I guess you mean a string containing JSON?

If so you can use the safe var myArray = JSON.parse(myJSON) method (either native or included using JSON2), or the usafe var myArray = eval("(" + myJSON + ")"). eval should normally be avoided, but if you are certain that the content is safe, then there is no problem.

After that you just iterate over the array as normal.

for (var i = 0; i < myArray.length; i++) {
    alert(myArray[i].Title);
}

Database Clustering is actually a mode of synchronous replication between two or possibly more nodes with an added functionality of fault tolerance added to your system, and that too in a shared nothing architecture. By shared nothing it means that the individual nodes actually don't share any physical resources like disk or memory.

As far as keeping the data synchronized is concerned, there is a management server to which all the data nodes are connected along with the SQL node to achieve this(talking specifically about MySQL).

Now about the differences: load balancing is just one result that could be achieved through clustering, the others include high availability, scalability and fault tolerance.

So first of all, pandas updates using the index. When an update command does not update anything, check both left-hand side and right-hand side. If you don't update the indices to follow your identification logic, you can do something along the lines of

>>> df.loc[df.filename == 'test2.dat', 'n'] = df2[df2.filename == 'test2.dat'].loc[0]['n']
>>> df
Out[331]: 
    filename   m     n
0  test0.dat  12  None
1  test2.dat  13    16

If you want to do this for the whole table, I suggest a method I believe is superior to the previously mentioned ones: since your identifier is filename, set filename as your index, and then use update() as you wanted to. Both merge and the apply() approach contain unnecessary overhead:

>>> df.set_index('filename', inplace=True)
>>> df2.set_index('filename', inplace=True)
>>> df.update(df2)
>>> df
Out[292]: 
            m     n
filename           
test0.dat  12  None
test2.dat  13    16

It seems that stopUpdatingLocation is what triggers the background watchdog timer, so I replaced it in didUpdateLocation with:

     [self.locationManager setDesiredAccuracy:kCLLocationAccuracyThreeKilometers];
     [self.locationManager setDistanceFilter:99999];

which appears to effectively power down the GPS. The selector for the background NSTimer then becomes:

- (void) changeAccuracy {
[self.locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
[self.locationManager setDistanceFilter:kCLDistanceFilterNone];
}

All I'm doing is periodically toggling the accuracy to get a high-accuracy coordinate every few minutes and because the locationManager hasn't been stopped, backgroundTimeRemaining stays at its maximum value. This reduced battery consumption from ~10% per hour (with constant kCLLocationAccuracyBest in the background) to ~2% per hour on my device

int i=10000;
byte b1=(byte)Color.alpha(i);
byte b2=(byte)Color.red(i);

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

Replace Null Values as Empty: ISNULL('Value','')

Replace Null Values as 0: ISNULL('Value',0)

You should use 'title' attribute along with 'data-toogle' (bootstrap).

For example

<i class="fa fa-info" data-toggle="tooltip" title="Hooray!"></i>Hover over me

and do not forget to add the javascript to display the tooltip

<script>
    $(document).ready(function(){
        $('[data-toggle="tooltip"]').tooltip();   
    });
</script>

Today we use Bearer token more often that Basic Authentication but if you want to have Basic Authentication first to get Bearer token then there is a couple ways:

const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
        // D some business logics here if you receive return
   if(request.readyState === 4 && request.status === 200) {
       console.log(request.responseText);
   }
}
request.send()

Full syntax is here

Second Approach using Ajax:

$.ajax
({
  type: "GET",
  url: "abc.xyz",
  dataType: 'json',
  async: false,
  username: "username",
  password: "password",
  data: '{ "key":"sample" }',
  success: function (){
    alert('Thanks for your up vote!');
  }
});

Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication or Oauth Authentication. Just explore it.

Opaque responses can't be accessed by JavaScript, but you can still cache them with the Cache API and respond with them in the fetch event handler in a service worker. So they're useful for making your app offline, also for resources that you can't control (e.g. resources on a CDN that doesn't set the CORS headers).

var hiddenFieldID = "input[id$=" + hiddenField + "]";
var requiredVal= $(hiddenFieldID).val();

To set the PATH variable, within the Makefile only, use something like:

PATH := $(PATH):/my/dir

test:
@echo my new PATH = $(PATH)

//The file that you wanna convert into byte[]
File file=new File("/storage/0CE2-EA3D/DCIM/Camera/VID_20190822_205931.mp4"); 

FileInputStream fileInputStream=new FileInputStream(file);
byte[] data=new byte[(int) file.length()];
BufferedInputStream bufferedInputStream=new BufferedInputStream(fileInputStream);
bufferedInputStream.read(data,0,data.length);

//Now the bytes of the file are contain in the "byte[] data"

I would recommend the rename command for this. Type ren /? at the command line for more help.

This solution is simple, elegant and works in all browsers:

var video = $("#playerid").attr("src");
$("#playerid").attr("src","");
$("#playerid").attr("src",video);

I know this might be coming very late, but it may prove useful to someone. So for appending key value pairs to dictionaries in swift, you can use updateValue(value: , forKey: ) method as follows :

var dict = [ 1 : "abc", 2 : "cde"]
dict.updateValue("efg", forKey: 3)
print(dict)

If the pattern inside .gitignore ends with a slash /, it will only find a match with a directory.

In other words, bin/ will match a directory bin and paths underneath it, but will not match a regular file or a symbolic link bin.

If the pattern does not contain a slash, like in bin Git treats it as a shell glob pattern (greedy). So best would be to use simple /bin.

bin would not be the best solution for this particular problem.

First thing, you should not do any DOM manipulation in controller function. Instead, you should use directives for this purpose. directive's link function is available for those kind of stuff only.

AngularJS Docs : Creating a Directive that Manipulates the DOM

app.directive('buttonDirective', function($timeout) {
  return {
    scope: {
       change: '&'
    },
    link: function(scope, element, attrs) {
      element.bind('click', function() {
        $timeout(function() {
          // triggering callback
          scope.change();
        });
      });
    }
  };
});

change callback can be used as listener for click event.

The problem could occur when $templateCacheProvider is trying to resolve a template in the templateCache or through your project directory that does not exist

Example:

templateUrl: 'views/wrongPathToTemplate'

Should be:

templateUrl: 'views/home.html'

Based on @davioooh answer. This code is worked for me.

ListObjectsRequest listObjectsRequest = new ListObjectsRequest().withBucketName("your-bucket")
            .withPrefix("your/folder/path/").withDelimiter("/");

To get .woff fonts first open the chrome dev tools panel (Ctrl+Shift+i) go to Network and reload the page. There you will see everything the page downloads. Find the .woff file, right click and select Copy response.

The response will be a url so paste it in the navigation bar. A file will be downloaded, just add the .woff extension to it and voila.

Slightly modified version of the above, including a custom page to be displayed to those who get denied access:

ErrorDocument 403 /specific_page.html
order deny,allow
deny from all
allow from 111.222.333.444

...and that way those requests not coming from 111.222.333.444 will see specific_page.html

Here's something I quickly just made and it should perform far better than File.getName().endsWith(".xxxx");

import java.io.File;
import java.io.FileFilter;

public class ExtensionsFilter implements FileFilter 
{
    private char[][] extensions;

    private ExtensionsFilter(String[] extensions)
    {
        int length = extensions.length;
        this.extensions = new char[length][];
        for (String s : extensions)
        {
            this.extensions[--length] = s.toCharArray();
        }
    }

    @Override
    public boolean accept(File file)
    {
        char[] path = file.getPath().toCharArray();
        for (char[] extension : extensions)
        {
            if (extension.length > path.length)
            {
                continue;
            }
            int pStart = path.length - 1;
            int eStart = extension.length - 1;
            boolean success = true;
            for (int i = 0; i <= eStart; i++)
            {
                if ((path[pStart - i] | 0x20) != (extension[eStart - i] | 0x20))
                {
                    success = false;
                    break;
                }
            }
            if (success)
                return true;
        }
        return false;
    }
}

Here's an example for various images formats.

private static final ExtensionsFilter IMAGE_FILTER = 
      new ExtensionsFilter(new String[] {".png", ".jpg", ".bmp"});

Header rows in data are a perpetual headache in Hive. Short of modifying the Hive source, I believe you can't get away without an intermediate step. (Edit: This is no longer true, see update below)

Unfortunately, that answers you question. I'll throw in some ideas for the intermediate step for completeness.

You can get away without an extra step in your data load if you are willing to filter out the header row on every query that touches the table. Unfortunately this adds an extra set just about everywhere else. And you will have to get clever/messy when the header row violates your schema. If you go with this approach, you might consider writing a custom SerDe that makes this row easier to filter. Unfortunately, SerDe's cannot remove the row entirely (or that might form a possible solution), they must return something like null. I've never seen this approach taken in practice to deal with header rows since it makes reading a pain, and reading tends to be much more common than writing. It might have a place if you are dealing with one-of tables or if the header row is just one row among many malformed rows.

You could do this filtering once with variations on deleting that first row in data load. A WHERE clause in an INSERT statement would do it. You could use utilities like sed to get rid of it. I've seen both approaches taken. There are trade-offs between which approach you take and neither is the one true way to deal with header rows. Unfortunately, both these approaches take time and require temporary duplication of the data. If you absolutely need the header row for another application, the duplication would be permanent.

Update:

From Hive v0.13.0, you can use skip.header.line.count. You could also specify the same while creating the table. For example:

create external table testtable (name string, message string)
row format delimited 
fields terminated by '\t' 
lines terminated by '\n' 
location '/testtable'
tblproperties ("skip.header.line.count"="1");

As other answers have mentioned, the following calls will compute the hash:

MD5Context md5;
MD5Init(&md5);
MD5Update(&md5, data, datalen);
MD5Final(digest, &md5);

The purpose of splitting it up into that many functions is to let you stream large datasets.

For example, if you're hashing a 10GB file and it doesn't fit into ram, here's how you would go about doing it. You would read the file in smaller chunks and call MD5Update on them.

MD5Context md5;
MD5Init(&md5);

fread(/* Read a block into data. */)
MD5Update(&md5, data, datalen);

fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);

fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);

...

//  Now finish to get the final hash value.
MD5Final(digest, &md5);

In my case I had to wait for a user interaction, so I set a click or touchend listener.

const isMobile = navigator.maxTouchPoints || "ontouchstart" in document.documentElement;

function play(){
    audioEl.play()
}


document.body.addEventListener(isMobile ? "touchend" : "click", play, { once: true });
