For the Collatz problem, you can get a significant boost in performance by caching the "tails". This is a time/memory trade-off. See: memoization (https://en.wikipedia.org/wiki/Memoization). You could also look into dynamic programming solutions for other time/memory trade-offs.

Example python implementation:

import sys

inner_loop = 0

def collatz_sequence(N, cache):
    global inner_loop

    l = [ ]
    stop = False
    n = N

    tails = [ ]

    while not stop:
        inner_loop += 1
        tmp = n
        l.append(n)
        if n <= 1:
            stop = True  
        elif n in cache:
            stop = True
        elif n % 2:
            n = 3*n + 1
        else:
            n = n // 2
        tails.append((tmp, len(l)))

    for key, offset in tails:
        if not key in cache:
            cache[key] = l[offset:]

    return l

def gen_sequence(l, cache):
    for elem in l:
        yield elem
        if elem in cache:
            yield from gen_sequence(cache[elem], cache)
            raise StopIteration

if __name__ == "__main__":
    le_cache = {}

    for n in range(1, 4711, 5):
        l = collatz_sequence(n, le_cache)
        print("{}: {}".format(n, len(list(gen_sequence(l, le_cache)))))

    print("inner_loop = {}".format(inner_loop))

Use FileSaver.js. It supports Chrome, Edge, Firefox, and IE 10+ (and probably IE < 10 with a few "polyfills" - see Note 4). FileSaver.js implements the saveAs() FileSaver interface in browsers that do not natively support it:
     https://github.com/eligrey/FileSaver.js

Minified version is really small at < 2.5KB, gzipped < 1.2KB.

Usage:

/* TODO: replace the blob content with your byte[] */
var blob = new Blob([yourBinaryDataAsAnArrayOrAsAString], {type: "application/octet-stream"});
var fileName = "myFileName.myExtension";
saveAs(blob, fileName);

You might need Blob.js in some browsers (see Note 3). Blob.js implements the W3C Blob interface in browsers that do not natively support it. It is a cross-browser implementation:
     https://github.com/eligrey/Blob.js

Consider StreamSaver.js if you have files larger than blob's size limitations.

Note 6: FileSaver.js examples: https://github.com/eligrey/FileSaver.js#examples

You JSON doesn't match your struct fields: E.g. "district" in JSON and "District" as the field.

Also: Your Item is a slice type but your JSON is a dict value. Do not mix this up. Slices decode from arrays.

I believe I have encountered the same quandary. I started encountering the problem when I changed to:

</system.web>
<httpRuntime targetFramework="4.5"/>

Which gives the error message you describe above.

adding:

<appSettings>
  <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />

Solves the issue, but then it makes your validation controls/scripts throw Javascript runtime errors. If you change to:

</system.web>
<httpRuntime targetFramework="4.0"/>

You should be OK, but you’ll have to make sure the rest of your code does/ behaves as desired. You might also have to forgo some new features only available in 4.5 onward.

P.S. It is highly recommended that you read the following before implementing this solution. Especially, if you use Async functionality:

https://blogs.msdn.microsoft.com/webdev/2012/11/19/all-about-httpruntime-targetframework/

UPDATE April 2017: After some some experimentation and testing I have come up with a combination that works:

<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
<httpRuntime targetFramework="4.5.1" />

with:

jQuery version 1.11.3

Remove all pods and install again.

Steps:

1. comment all pods and run pod install
2. uncomment all pods and run pod install

I had this issue today on a repo.

It wasn't the +refs/heads/*:refs/remotes/origin/* issue as per top solution.

Symptom was simply that git fetch origin or git fetch just didn't appear to do anything, although there were remote branches to fetch.

After trying lots of things, I removed the origin remote, and recreated it. That seems to have fixed it. Don't know why.

remove with: git remote rm origin

and recreate with: git remote add origin <git uri>

here is another solution...

System.IO.Stream st = new System.IO.StreamReader (picturePath).BaseStream;
byte[] buffer = new byte[4096];

System.IO.MemoryStream m = new System.IO.MemoryStream ();
while (st.Read (buffer,0,buffer.Length) > 0) {
    m.Write (buffer, 0, buffer.Length);
}  
imgView.Tag = m.ToArray ();
st.Close ();
m.Close ();

hope it helps!

Does your HOSTS file have an entry for localhost? Some other situations this error is seen in seem to have this as a problem resolution.

Make sure you have 127.0.0.1 localhost set in it...

(from this and this)

Great question... I wish there was an answer, but this is the closest you can get with CSS these days. No ellipsis, but still pretty usable.

overflow: hidden;
line-height: 1.2em;
height: 3.6em;      // 3 lines * line-height

None of these answers seemed simple enough - the crux of the problem is not having to rebuild:

makefile

OBJDIR=out
VPATH=$(OBJDIR)

# make will look in VPATH to see if the target needs to be rebuilt
test: moo
    touch $(OBJDIR)/$@

example use

touch moo
# creates out/test
make test
# doesn't update out/test
make test
# will now update test
touch moo
make test

Disabling 'Show Logical Structure' button/icon of the upper right corner of the variables window in the eclipse debugger resolved it, in my case.

Scrolling with animation:

Your DIV:

<div class='messageScrollArea' style='height: 100px;overflow: auto;'>
      Hello World! Hello World! Hello World! Hello World! Hello World! Hello
      Hello World! Hello World! Hello World! Hello World! Hello World! Hello
      Hello World! Hello World! Hello World! Hello World! Hello World! Hello
</div>

jQuery part:

jQuery(document).ready(function(){       
    var $t = $('.messageScrollArea');
    $t.animate({"scrollTop": $('.messageScrollArea')[0].scrollHeight}, "slow");
});

If you are using Java 1.4 or newer, you can use the simple method setLocationRelativeTo(null) on the dialog box, frame, or window to center it.

Here is a trick I use with GNU make for creating compiler-output directories. First define this rule:

  %/.d:
          mkdir -p $(@D)
          touch $@

Then make all files that go into the directory dependent on the .d file in that directory:

 obj/%.o: %.c obj/.d
    $(CC) $(CFLAGS) -c -o $@ $<

Note use of $< instead of $^.

Finally prevent the .d files from being removed automatically:

 .PRECIOUS: %/.d

Skipping the .d file, and depending directly on the directory, will not work, as the directory modification time is updated every time a file is written in that directory, which would force rebuild at every invocation of make.

Put a global statement at the top of your function and you should be good:

def onLoadFinished(result):
    global feed
    ...

To demonstrate what I mean, look at this little test:

x = 0
def t():
    x += 1
t()

this blows up with your exact same error where as:

x = 0
def t():
    global x
    x += 1
t()

does not.

The reason for this is that, inside t, Python thinks that x is a local variable. Furthermore, unless you explicitly tell it that x is global, it will try to use a local variable named x in x += 1. But, since there is no x defined in the local scope of t, it throws an error.

To create table structure only use this below code :

CREATE TABLE new_table LIKE current_table; 

To copy data from table to another use this below code :

INSERT INTO new_table SELECT * FROM current_table;

To install this product you can see this tutorial: OpenCV on Ubuntu

There are listed the packages you need. So, with:

# dpkg -l | grep libcv2
# dpkg -l | grep libhighgui2

and more listed in the url you can find which packages are installed.

With

# dpkg -L libcv2

you can check where are installed

This operative is used for all debian packages.

I would say that while both are correct mathematically, implementation-wise, first one is better. When computing softmax, the intermediate values may become very large. Dividing two large numbers can be numerically unstable. These notes (from Stanford) mention a normalization trick which is essentially what you are doing.

To start with, from the Oracle Database Data Warehousing Guide:

Restrictions on Fast Refresh on Materialized Views with Joins Only

...

• Rowids of all the tables in the FROM list must appear in the SELECT list of the query.

This means that your statement will need to look something like this:

CREATE MATERIALIZED VIEW MV_Test
  NOLOGGING
  CACHE
  BUILD IMMEDIATE 
  REFRESH FAST ON COMMIT 
  AS
    SELECT V.*, P.*, V.ROWID as V_ROWID, P.ROWID as P_ROWID 
    FROM TPM_PROJECTVERSION V,
         TPM_PROJECT P 
    WHERE P.PROJECTID = V.PROJECTID

Another key aspect to note is that your materialized view logs must be created as with rowid.

Below is a functional test scenario:

CREATE TABLE foo(foo NUMBER, CONSTRAINT foo_pk PRIMARY KEY(foo));

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

To answer all your questions:

Can I use ROBOCOPY for this?

Yes, RC should fit your requirements (simplicity, only copy what needed)

What exactly does it mean to exclude?

It will exclude copying - RC calls it skipping

Would the /XO option copy only newer files, not files of the same age?

Yes, RC will only copy newer files. Files of the same age will be skipped.

(the correct command would be robocopy C:\SourceFolder D:\DestinationFolder ABC.dll /XO)

Maybe in your case using the /MIR option could be useful. In general RC is rather targeted at directories and directory trees than single files.

Use the Moment.js library http://momentjs.com/ It will save you a LOT of trouble.

moment().format('DD-MMM-YYYY');

Example:

Model:

public class MyViewModel
{
    [Required]
    public string Foo { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return Content("Thanks", "text/html");
    }
}

View:

@model AppName.Models.MyViewModel

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

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

@using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "result" }))
{
    @Html.EditorFor(x => x.Foo)
    @Html.ValidationMessageFor(x => x.Foo)
    <input type="submit" value="OK" />
}

and here's a better (in my perspective) example:

View:

@model AppName.Models.MyViewModel

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

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

@using (Html.BeginForm())
{
    @Html.EditorFor(x => x.Foo)
    @Html.ValidationMessageFor(x => x.Foo)
    <input type="submit" value="OK" />
}

index.js:

$(function () {
    $('form').submit(function () {
        if ($(this).valid()) {
            $.ajax({
                url: this.action,
                type: this.method,
                data: $(this).serialize(),
                success: function (result) {
                    $('#result').html(result);
                }
            });
        }
        return false;
    });
});

which can be further enhanced with the jQuery form plugin.

Use COPY command like this:

COPY foo.txt /data/foo.txt
# where foo.txt is the relative path on host
# and /data/foo.txt is the absolute path in the image

read more details for COPY in the official documentation

An alternative would be to use ADD but this is not the best practise if you dont want to use some advanced features of ADD like decompression of tar.gz files.If you still want to use ADD command, do it like this:

ADD abc.txt /data/abc.txt
# where abc.txt is the relative path on host
# and /data/abc.txt is the absolute path in the image

read more details for ADD in the official documentation

You need some tools like pdf2text to first convert your pdf to a text file and then search inside the text. (You will probably miss some information or symbols).

If you are using a programming language there are probably pdf libraries written for this purpose. e.g. http://search.cpan.org/dist/CAM-PDF/ for Perl

FOR WITHIN TEMPLATES

This is how I usually get current logged in user and their id in my templates.

<p>Your Username is : {{user}} </p>
<p>Your User Id is  : {{user.id}} </p>

Try the following:

 Paint textPaint = new Paint();
 textPaint.setTextAlign(Paint.Align.CENTER);

 int xPos = (canvas.getWidth() / 2);
 int yPos = (int) ((canvas.getHeight() / 2) - ((textPaint.descent() + textPaint.ascent()) / 2)) ; 
 //((textPaint.descent() + textPaint.ascent()) / 2) is the distance from the baseline to the center.

 canvas.drawText("Hello", xPos, yPos, textPaint);

A little bit late for the party, but it's an interessting question.

You can write your own inc.bat for incrementing a number.
It can increment numbers from 0 to 9998.

@echo off
if "%1"==":inc" goto :increment

call %0 :inc %counter0%
set counter0=%_cnt%
if %_overflow%==0 goto :exit 

call %0 :inc %counter1%
set counter1=%_cnt%
if %_overflow%==0 goto :exit 

call %0 :inc %counter2%
set counter2=%_cnt%
if %_overflow%==0 goto :exit 

call %0 :inc %counter3%
set counter3=%_cnt%
goto :exit

:increment
set _overflow=0
set _cnt=%2

if "%_cnt%"=="" set _cnt=0

if %_cnt%==9 goto :overflow
if %_cnt%==8 set _cnt=9
if %_cnt%==7 set _cnt=8
if %_cnt%==6 set _cnt=7
if %_cnt%==5 set _cnt=6
if %_cnt%==4 set _cnt=5
if %_cnt%==3 set _cnt=4
if %_cnt%==2 set _cnt=3
if %_cnt%==1 set _cnt=2
if %_cnt%==0 set _cnt=1
goto :exit

:overflow
set _cnt=0
set _overflow=1
goto :exit

:exit
set count=%counter3%%counter2%%counter1%%counter0%

A sample for using it is here

@echo off
set counter0=0
set counter1=
set counter2=
set counter3=

:loop
call inc.bat
echo %count%
if not %count%==250 goto :loop

Make sure you are running the test as a superuser.

sudo nginx -t

Or the test wont have all the permissions needed to complete the test properly.

You should implement a Custom List View, such that you define a Layout once and draw it for every row in the list view.

Using the "file" command may be useful for this:

#!/bin/bash
check_file(){

if [ -z "${1}" ] ;then
 echo "Please input something"
 return;
fi

f="${1}"
result="$(file $f)"
if [[ $result == *"cannot open"* ]] ;then
        echo "NO FILE FOUND ($result) ";
elif [[ $result == *"directory"* ]] ;then
        echo "DIRECTORY FOUND ($result) ";
else
        echo "FILE FOUND ($result) ";
fi

}

check_file "${1}"

Output examples :

$ ./f.bash login
DIRECTORY FOUND (login: directory) 
$ ./f.bash ldasdas
NO FILE FOUND (ldasdas: cannot open `ldasdas' (No such file or  directory)) 
$ ./f.bash evil.php 
FILE FOUND (evil.php: PHP script, ASCII text) 

FYI: the answers above work but you can use -s to help in weird situations by checking for a valid file first:

#!/bin/bash

check_file(){
    local file="${1}"
    [[ -s "${file}" ]] || { echo "is not valid"; return; } 
    [[ -d "${file}" ]] && { echo "is a directory"; return; }
    [[ -f "${file}" ]] && { echo "is a file"; return; }
}

check_file ${1}

If you want to discard the array at the same time as summing, you could do (say, stack is the array):

var stack = [1,2,3],
    sum = 0;
while(stack.length > 0) { sum += stack.pop() };

I am on Windows and I had to modify sdk path irrespective of having it in PATH env. variable

It's probably worth mentioning that for http/https some people proxy their browser traffic through Burp/ZAP or another intercepting "attack proxy". A thread that covers options for this on Android devices can be found here: https://android.stackexchange.com/questions/32366/which-browser-does-support-proxies

My descriptions for the three:

• offsetHeight: How much of the parent's "relative positioning" space is taken up by the element. (ie. it ignores the element's position: absolute descendents)
• clientHeight: Same as offset-height, except it excludes the element's own border, margin, and the height of its horizontal scroll-bar (if it has one).
• scrollHeight: How much space is needed to see all of the element's content/descendents (including position: absolute ones) without scrolling.

Then there is also:

• getBoundingClientRect().height: Same as scrollHeight, except that it's calculated after the element's css transforms are applied.

Could you not cast your result as numeric(x,2)? Where x <= 38

select 
    round(630/60.0,2), 
    cast(round(630/60.0,2) as numeric(36,2))

Returns

10.500000   10.50

For a deep copy, ICloneable is the correct solution, but here's a similar approach to ICloneable using the constructor instead of the ICloneable interface.

public class Student
{
  public Student(Student student)
  {
    FirstName = student.FirstName;
    LastName = student.LastName;
  }

  public string FirstName { get; set; }
  public string LastName { get; set; }
}

// wherever you have the list
List<Student> students;

// and then where you want to make a copy
List<Student> copy = students.Select(s => new Student(s)).ToList();

you'll need the following library where you make the copy

using System.Linq

you could also use a for loop instead of System.Linq, but Linq makes it concise and clean. Likewise you could do as other answers have suggested and make extension methods, etc., but none of that is necessary.

public static void main(String s[]) 
  {

    BufferedImage image = null;
    try 
    {
        image = ImageIO.read(new File("your image path"));

    } catch (Exception e) 
    {
        e.printStackTrace();
    }

    ImageIcon imageIcon = new ImageIcon(fitimage(image, label.getWidth(), label.getHeight()));
    jLabel1.setIcon(imageIcon);
}


private Image fitimage(Image img , int w , int h)
{
    BufferedImage resizedimage = new BufferedImage(w,h,BufferedImage.TYPE_INT_RGB);
    Graphics2D g2 = resizedimage.createGraphics();
    g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
    g2.drawImage(img, 0, 0,w,h,null);
    g2.dispose();
    return resizedimage;
}

use sql server manegement studio or netcat and that will be easier to manipulate sql

My approach was as follows (in PHP):

$url = "whatever_you_need"

$html = file_get_contents('https://en.wikipedia.org/w/api.php?action=opensearch&search='.$url);
$utf8html = html_entity_decode(preg_replace("/U\+([0-9A-F]{4})/", "&#x\\1;", $html), ENT_NOQUOTES, 'UTF-8');

$utf8html might need further cleaning, but that's basically it.

you can use

<meta http-equiv="refresh" content="10" > 

just add it after the head tags

where 10 is the time your page will refresh itself

The error occur mainly becuase the array isnt found. Just check if you have mapped to the correct array. Check the array name or declaration.

    // pop back stack all the way
    final FragmentManager fm = getSherlockActivity().getSupportFragmentManager();
    int entryCount = fm.getBackStackEntryCount(); 
    while (entryCount-- > 0) {
        fm.popBackStack();
    }

.nvmrc

If you are using NVM like this, which you likely should, then you can indicate the nodejs version required for given project in a git-tracked .nvmrc file:

echo v10.15.1 > .nvmrc

This does not take effect automatically on cd, which is sane: the user must then do a:

nvm use

and now that version of node will be used for the current shell.

You can list the versions of node that you have with:

nvm list

.nvmrc is documented at: https://github.com/creationix/nvm/tree/02997b0753f66c9790c6016ed022ed2072c22603#nvmrc

How to automatically select that node version on cd was asked at: Automatically switch to correct version of Node based on project

Tested with NVM 0.33.11.

I've faced this issue because during bootstrapping my spring project using the class that implements ApplicationListener<ContextRefreshedEvent> and inside onApplicationEvent function it throws an exception

so make sure that your application bootstrap points do not throw any exception

in my case, I was using maven surefire plugin for testing so to debug the test process use this command

mvn -Dmaven.surefire.debug test

You can use the reset() function, it will return the first array member.

I understand that this is a response to an old post-

I like the If() function combined with Index()/Match():

=IF(B2>0,"x",INDEX($H$2:$I$9,MATCH(A2,$H$2:$H$9,0),2))

The if function compare what is in column b and if it is greater than 0, it returns x, if not it uses the array (table of information) identified by the Index() function and selected by Match() to return the value that a corresponds to.

The Index array has the absolute location set $H$2:$I$9 (the dollar signs) so that the place it points to will not change as the formula is copied. The row with the value that you want returned is identified by the Match() function. Match() has the added value of not needing a sorted list to look through that Vlookup() requires. Match() can find the value with a value: 1 less than, 0 exact, -1 greater than. I put a zero in after the absolute Match() array $H$2:$H$9 to find the exact match. For the column that value of the Index() array that one would like returned is entered. I entered a 2 because in my array the return value was in the second column. Below my index array looked like this:

32   1420

36   1650

40   1790

44   1860

55   2010

The value in your 'a' column to search for in the list is in the first column in my example and the corresponding value that is to be return is to the right. The look up/reference table can be on any tab in the work book - or even in another file. -Book2 is the file name, and Sheet2 is the 'other tab' name.

=IF(B2>0,"x",INDEX([Book2]Sheet2!$A$1:$B$8,MATCH(A2,[Book2]Sheet2!$A$1:$A$8,0),2))

If you do not want x return when the value of b is greater than zero delete the x for a 'blank'/null equivalent or maybe put a 0 - not sure what you would want there.

Below is beginning of the function with the x deleted.

=IF(B2>0,"",INDEX...

Short Answer

To make a clean install of Python 3.6.5 use:

brew unlink python # ONLY if you have installed (with brew) another version of python 3
brew install --ignore-dependencies https://raw.githubusercontent.com/Homebrew/homebrew-core/f2a764ef944b1080be64bd88dca9a1d80130c558/Formula/python.rb

If you prefer to recover a previously installed version, then:

brew info python           # To see what you have previously installed
brew switch python 3.x.x_x # Ex. 3.6.5_1

Long Answer

There are two formulas for installing Python with Homebrew: python@2 and python.
The first is for Python 2 and the second for Python 3.

Note: You can find outdated answers on the web where it is mentioned python3 as the formula name for installing Python version 3. Now it's just python!

By default, with these formulas you can install the latest version of the corresponding major version of Python. So, you cannot directly install a minor version like 3.6.

Solution

With brew, you can install a package using the address of the formula, for example in a git repository.

brew install https://the/address/to/the/formula/FORMULA_NAME.rb

Or specifically for Python 3

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/COMMIT_IDENTIFIER/Formula/python.rb

The address you must specify is the address to the last commit of the formula (python.rb) for the desired version. You can find the commint identifier by looking at the history for homebrew-core/Formula/python.rb

https://github.com/Homebrew/homebrew-core/commits/master/Formula/python.rb

Python > 3.6.5

In the link above you will not find a formula for a version of Python above 3.6.5. After the maintainers of that (official) repository released Python 3.7, they only submit updates to the recipe of Python 3.7.

As explained above, with homebrew you have only Python 2 (python@2) and Python 3 (python), there is no explicit formula for Python 3.6.

Although those minor updates are mostly irrelevant in most cases and for most users, I will search if someone has done an explicit formula for 3.6.

So there might be a few things wrong here.

First start by reading how to use XMLHttpRequest.open() because there's a third optional parameter for specifying whether to make an asynchronous request, defaulting to true. That means you're making an asynchronous request and need to specify a callback function before you do the send(). Here's an example from MDN:

var oXHR = new XMLHttpRequest();

oXHR.open("GET", "http://www.mozilla.org/", true);

oXHR.onreadystatechange = function (oEvent) {
    if (oXHR.readyState === 4) {
        if (oXHR.status === 200) {
          console.log(oXHR.responseText)
        } else {
           console.log("Error", oXHR.statusText);
        }
    }
};

oXHR.send(null);

Second, since you're getting a 101 error, you might use the wrong URL. So make sure that the URL you're making the request with is correct. Also, make sure that your server is capable of serving your quiz.xml file.

You'll probably have to debug by simplifying/narrowing down where the problem is. So I'd start by making an easy synchronous request so you don't have to worry about the callback function. So here's another example from MDN for making a synchronous request:

var request = new XMLHttpRequest();
request.open('GET', 'file:///home/user/file.json', false); 
request.send(null);

if (request.status == 0)
    console.log(request.responseText);

Also, if you're just starting out with Javascript, you could refer to MDN for Javascript API documentation/examples/tutorials.

• input = numpy_image
• np.unit8 -> converts to integers
• convert('RGB') -> converts to RGB

• Image.fromarray -> returns an image object

  from PIL import Image
  import numpy as np
  
  PIL_image = Image.fromarray(np.uint8(numpy_image)).convert('RGB')
  
  PIL_image = Image.fromarray(numpy_image.astype('uint8'), 'RGB')
  

Yes, there is a maximum, but it's system dependent. Try it and see, doubling until you hit a limit then searching down. At least with Sun JRE 1.6 on linux you get interesting if not always informative error messages (peregrino is netbook running 32 bit ubuntu with 2G RAM and no swap):

peregrino:$ java -Xmx4096M -cp bin WheelPrimes 
Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.

peregrino:$ java -Xmx4095M -cp bin WheelPrimes 
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified

peregrino:$ java -Xmx4092M -cp bin WheelPrimes 
Error occurred during initialization of VM
The size of the object heap + VM data exceeds the maximum representable size

peregrino:$ java -Xmx4000M -cp bin WheelPrimes 
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

(experiment reducing from 4000M until)

peregrino:$ java -Xmx2686M -cp bin WheelPrimes 
(normal execution)

Most are self explanatory, except -Xmx4095M which is rather odd (maybe a signed/unsigned comparison?), and that it claims to reserve 2686M on a 2GB machine with no swap. But it does hint that the maximum size is 4G not 2G for a 32 bit VM, if the OS allows you to address that much.

In simple terms, inside a then handler function:

A) When x is a value (number, string, etc):

1. return x is equivalent to return Promise.resolve(x)
2. throw x is equivalent to return Promise.reject(x)

B) When x is a Promise that is already settled (not pending anymore):

1. return x is equivalent to return Promise.resolve(x), if the Promise was already resolved.
2. return x is equivalent to return Promise.reject(x), if the Promise was already rejected.

C) When x is a Promise that is pending:

1. return x will return a pending Promise, and it will be evaluated on the subsequent then.

Read more on this topic on the Promise.prototype.then() docs.

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
   #myElement {
        /* Enter your style code */
   }
}

Explanation: It is a Microsoft-specific media query. Using -ms-high-contrast property specific to Microsoft IE, it will only be parsed in Internet Explorer 10 or greater. I have used both the valid values of the media query, so it will be parsed by IE only, whether the user has high contrast enabled or not.

Inserting at a specific index (rather than, say, at the first space character) has to use string slicing/substring:

var txt2 = txt1.slice(0, 3) + "bar" + txt1.slice(3);

First, let's note that git push "wants" two more arguments and will make them up automatically if you don't supply them. The basic command is therefore git push remote refspec.

The remote part is usually trivial as it's almost always just the word origin. The trickier part is the refspec. Most commonly, people write a branch name here: git push origin master, for instance. This uses your local branch to push to a branch of the same name¹ on the remote, creating it if necessary. But it doesn't have to be just a branch name.

In particular, a refspec has two colon-separated parts. For git push, the part on the left identifies what to push,² and the part on the right identifies the name to give to the remote. The part on the left in this case would be branch_name and the part on the right would be branch_name_test. For instance:

git push origin foo:foo_test

As you are doing the push, you can tell your git push to set your branch's upstream name at the same time, by adding -u to the git push options. Setting the upstream name makes your git save the foo_test (or whatever) name, so that a future git push with no arguments, while you're on the foo branch, can try to push to foo_test on the remote (git also saves the remote, origin in this case, so that you don't have to enter that either).

You need only pass -u once: it basically just runs git branch --set-upstream-to for you. (If you pass -u again later, it re-runs the upstream-setting, changing it as directed; or you can run git branch --set-upstream-to yourself.)

However, if your git is 2.0 or newer, and you have not set any special configuration, you will run into the same kind of thing that had me enter footnote 1 above: push.default will be set to simple, which will refuse to push because the upstream's name differs from your own local name. If you set push.default to upstream, git will stop complaining—but the simplest solution is just to rename your local branch first, so that the local and remote names match. (What settings to set, and/or whether to rename your branch, are up to you.)

¹More precisely, git consults your remote.remote.push setting to derive the upstream half of the refspec. If you haven't set anything here, the default is to use the same name.

²This doesn't have to be a branch name. For instance, you can supply HEAD, or a commit hash, here. If you use something other than a branch name, you may have to spell out the full refs/heads/branch on the right, though (it depends on what names are already on the remote).

Good Semantics is important in programming.

Utilizing more methods besides GET/POST will be helpful because it will increase the readability of your code and make it easier to maintain.

Why?

Because you know GET will retrieve data from your api. You know POST will add new data to your system. You know PUT will make updates. DELETE will delete rows etc, etc,

I normally structure my RESTFUL Web Services so that I have a function callback named the same thing as the method.

I use PHP, so I use function_exists (I think its called). If the function doesn't exist, I throw a 405 (METHOD NOT ALLOWED).

Here is how I solved the issue, might be useful to some:

Ajax modal doesn't seem to be available with boostrap 2.1.1

So I ended up coding it myself:

$('[data-toggle="modal"]').click(function(e) {
  e.preventDefault();
  var url = $(this).attr('href');
  //var modal_id = $(this).attr('data-target');
  $.get(url, function(data) {
      $(data).modal();
  });
});

Example of a link that calls a modal:

<a href="{{ path('ajax_get_messages', { 'superCategoryID': 6, 'sex': sex }) }}" data-toggle="modal">
    <img src="{{ asset('bundles/yopyourownpoet/images/messageCategories/BirthdaysAnniversaries.png') }}" alt="Birthdays" height="120" width="109"/>
</a>

I now send the whole modal markup through ajax.

This happens when your table structure and model class no longer in sync. You need to update the table structure according to the model class or vice versa -- this is when your data is important and must not be deleted. If your data structure has changed and the data isn't important to you, you can use the DropCreateDatabaseIfModelChanges feature (formerly known as 'RecreateDatabaseIfModelChanges' feature) by adding the following code in your Global.asax.cs:

Database.SetInitializer<MyDbContext>(new DropCreateDatabaseIfModelChanges<MyDbContext>());

Run your application again.

As the name implies, this will drop your database and recreate according to your latest model class (or classes) -- provided you believe the table structure definitions in your model classes are the most current and latest; otherwise change the property definitions of your model classes instead.

use datejs

new Date().toString('yyyy-MM-d-h-mm-ss');

All in one solution. Gives no units with zeroes. Will only produce number of units you specify (3 by default). Quite long, perhaps not very elegant. Defines are optional, but might come in handy in a big project.

define('OneMonth', 2592000);
define('OneWeek', 604800);  
define('OneDay', 86400);
define('OneHour', 3600);    
define('OneMinute', 60);

function SecondsToTime($seconds, $num_units=3) {        
    $time_descr = array(
                "months" => floor($seconds / OneMonth),
                "weeks" => floor(($seconds%OneMonth) / OneWeek),
                "days" => floor(($seconds%OneWeek) / OneDay),
                "hours" => floor(($seconds%OneDay) / OneHour),
                "mins" => floor(($seconds%OneHour) / OneMinute),
                "secs" => floor($seconds%OneMinute),
                );  

    $res = "";
    $counter = 0;

    foreach ($time_descr as $k => $v) {
        if ($v) {
            $res.=$v." ".$k;
            $counter++;
            if($counter>=$num_units)
                break;
            elseif($counter)
                $res.=", ";             
        }
    }   
    return $res;
}

Feel free to down-vote, but be sure to try it in your code. It might just be what you need.

All older answers' methods are deprecated by Google (supposedly because of troubles like this), since API 21 you need to use the Camera 2 API:

This class was deprecated in API level 21. We recommend using the new android.hardware.camera2 API for new applications.

In the newer API you have almost complete power over the Android device camera and documentation explicitly advice to

String[] getCameraIdList()

and then use obtained CameraId to open the camera:

void openCamera(String cameraId, CameraDevice.StateCallback callback, Handler handler)

99% of the frontal cameras have id = "1", and the back camera id = "0" according to this:

Non-removable cameras use integers starting at 0 for their identifiers, while removable cameras have a unique identifier for each individual device, even if they are the same model.

However, this means if device situation is rare like just 1-frontal -camera tablet you need to count how many embedded cameras you have, and place the order of the camera by its importance ("0"). So CAMERA_FACING_FRONT == 1 CAMERA_FACING_BACK == 0, which implies that the back camera is more important than frontal.

I don't know about a uniform method to identify the frontal camera on all Android devices. Simply said, the Android OS inside the device can't really find out which camera is exactly where for some reasons: maybe the only camera hardcoded id is an integer representing its importance or maybe on some devices whichever side you turn will be .. "back".

Documentation: https://developer.android.com/reference/android/hardware/camera2/package-summary.html

Explicit Examples: https://github.com/googlesamples/android-Camera2Basic

For the older API (it is not recommended, because it will not work on modern phones newer Android version and transfer is a pain-in-the-arse). Just use the same Integer CameraID (1) to open frontal camera like in this answer:

cam = Camera.open(1);

If you trust OpenCV to do the camera part:

Inside

    <org.opencv.android.JavaCameraView
    ../>

use the following for the frontal camera:

        opencv:camera_id="1"

The easiest way of doing this is using pdfHTML. It's an iText7 add-on that converts HTML5 (+CSS3) into pdf syntax.

The code is pretty straightforward:

    HtmlConverter.convertToPdf(
        "<b>This text should be written in bold.</b>",       // html to be converted
        new PdfWriter(
            new File("C://users/mark/documents/output.pdf")  // destination file
        )
    );

To learn more, go to http://itextpdf.com/itext7/pdfHTML

NOTE: Programs compiled with high-optimization levels (-O3, -O4) cannot generate many debugging symbols for optimized variables, in-lined functions and unrolled loops, regardless of the symbols being embedded (-g) or extracted (objcopy) into a '.debug' file.

Alternate approaches are

1. Embed the versioning (VCS, git, svn) data into the program, for compiler optimized executables (-O3, -O4).
2. Build a 2nd non-optimized version of the executable.

The first option provides a means to rebuild the production code with full debugging and symbols at a later date. Being able to re-build the original production code with no optimizations is a tremendous help for debugging. (NOTE: This assumes testing was done with the optimized version of the program).

Your build system can create a .c file loaded with the compile date, commit, and other VCS details. Here is a 'make + git' example:

program: program.o version.o 

program.o: program.cpp program.h 

build_version.o: build_version.c    

build_version.c: 
    @echo "const char *build1=\"VCS: Commit: $(shell git log -1 --pretty=%H)\";" > "$@"
    @echo "const char *build2=\"VCS: Date: $(shell git log -1 --pretty=%cd)\";" >> "$@"
    @echo "const char *build3=\"VCS: Author: $(shell git log -1 --pretty="%an %ae")\";" >> "$@"
    @echo "const char *build4=\"VCS: Branch: $(shell git symbolic-ref HEAD)\";" >> "$@"
    # TODO: Add compiler options and other build details

.TEMPORARY: build_version.c

After the program is compiled you can locate the original 'commit' for your code by using the command: strings -a my_program | grep VCS

VCS: PROGRAM_NAME=my_program
VCS: Commit=190aa9cace3b12e2b58b692f068d4f5cf22b0145
VCS: BRANCH=refs/heads/PRJ123_feature_desc
VCS: AUTHOR=Joe Developer  [email protected]
VCS: COMMIT_DATE=2013-12-19

All that is left is to check-out the original code, re-compile without optimizations, and start debugging.

I usually do:

sudo bash -c 'whoami; whoami'

Firstly a warning: you should never tinker with DOM that is managed by React, which you are doing by calling ReactDOM.render(<SampleComponent ... />);

With React, you should use SampleComponent directly in the main App.

var App = require('./App.js');
var SampleComponent = require('./SampleComponent.js');
ReactDOM.render(<App/>, document.body);

The content of your Component is irrelevant, but it should be used like this:

var App = React.createClass({
    render: function() {
        return (
            <div>
                <h1>App main component! </h1>
                <SampleComponent name="SomeName"/>
            </div>
        );
    }
});

You can then extend your app component to use a list.

var App = React.createClass({
    render: function() {
        var componentList = [
            <SampleComponent name="SomeName1"/>,
            <SampleComponent name="SomeName2"/>
        ]; // Change this to get the list from props or state
        return (
            <div>
                <h1>App main component! </h1>
                {componentList}
            </div>
        );
    }
});

I would really recommend that you look at the React documentation then follow the "Get Started" instructions. The time you spend on that will pay off later.

You can use the response.text to write to a file:

import requests

files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("resp_text.txt", "w")
file.write(response.text)
file.close()
file = open("resp_content.txt", "w")
file.write(response.text)
file.close()

Use the parent axes with the parent node's name.

//*[title="50"]/parent::store

This XPath will only select the parent node if it is a store.

But you can also use one of these

//*[title="50"]/parent::*
//*[title="50"]/..

These xpaths will select any parent node. So if the document changes you will always select a node, even if it is not the node you expect.

EDIT

What happens in the given example where the parent is a bicycle but the parent of the parent is a store?

Does it ascent?

No, it only selects the store if it is a parent of the node that matches //*[title="50"].

If not, is there a method to ascent in such cases and return None if there is no such parent?

Yes, you can use ancestor axes

//*[title="50"]/ancestor::store

This will select all ancestors of the node matching //*[title="50"] that are ` stores. E.g.

<data xmlns:d="defiant-namespace" d:mi="23">
    <store mi="1">
        <store mi="22">
            <book price="8.95" d:price="Number" d:mi="13">
                <title d:constr="String" d:mi="10">50</title>
                <category d:constr="String" d:mi="11">reference</category>
                <author d:constr="String" d:mi="12">Nigel Rees</author>
            </book>
        </store>
    </store>
</data>

In Powershell 7 you can use ForEach-Object -Parallel

$Message = "Output:"
Get-ChildItem $dir | ForEach-Object -Parallel {
    "$using:Message $_"
} -ThrottleLimit 4

sed '/^$/d' should be fine, are you expecting to modify the file in place? If so you should use the -i flag.

Maybe those lines are not empty, so if that's the case, look at this question Remove empty lines from txtfiles, remove spaces from start and end of line I believe that's what you're trying to achieve.

Simple and dynamic solution (Swift 5):

extension FileManager {

  class func directoryUrl() -> URL? {
      let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
      return paths.first
  }

  class func allRecordedData() -> [URL]? {
     if let documentsUrl = FileManager.directoryUrl() {
        do {
            let directoryContents = try FileManager.default.contentsOfDirectory(at: documentsUrl, includingPropertiesForKeys: nil)
            return directoryContents.filter{ $0.pathExtension == "m4a" }
        } catch {
            return nil
        }
     }
     return nil
  }}

Noticing that user 42-'s perfect approach {
* "do while" = "repeat until not"
* The code equivalence:

do while (condition) # in other language
..statements..
endo

repeat{ # in R
  ..statements..
  if(! condition){ break } # Negation is crucial here!
}

} did not receive enough attention from the others, I'll emphasize and bring forward his approach via a concrete example. If one does not negate the condition in do-while (via ! or by taking negation), then distorted situations (1. value persistence 2. infinite loop) exist depending on the course of the code.

In Gauss:

proc(0)=printvalues(y);
DO WHILE y < 5;    
y+1;
 y=y+1;
ENDO;
ENDP;
printvalues(0); @ run selected code via F4 to get the following @
       1.0000000 
       2.0000000 
       3.0000000 
       4.0000000 
       5.0000000 

In R:

printvalues <- function(y) {
repeat {
 y=y+1;
print(y)
if (! (y < 5) ) {break}   # Negation is crucial here!
}
}
printvalues(0)
# [1] 1
# [1] 2
# [1] 3
# [1] 4
# [1] 5

I still insist that without the negation of the condition in do-while, Salcedo's answer is wrong. One can check this via removing negation symbol in the above code.

Example 1 is for asp.net applications using forms authenication. This is common practice for internet applications because user is unauthenticated until it is authentcation against some security module.

Example 2 is for asp.net application using windows authenication. Windows Authentication uses Active Directory to authenticate users. The will prevent access to your application. I use this feature on intranet applications.

SQLAlchemy introduced that in version 1.0.0:

Bulk operations - SQLAlchemy docs

With these operations, you can now do bulk inserts or updates!

For instance, you can do:

s = Session()
objects = [
    User(name="u1"),
    User(name="u2"),
    User(name="u3")
]
s.bulk_save_objects(objects)
s.commit()

Here, a bulk insert will be made.

Yes you can as said by @tomer above. i want to add some point to @tomer answer.

• firstly you need to provide name to the router-outlet where you want to load the second routing view in your view. (aux routing angular2.)

• In angular2 routing few important points are here.

  • path or aux (requires exactly one of these to give the path you have to show as the url).
  • component, loader, redirectTo (requires exactly one of these, which component you want to load on routing)
  • name or as (optional) (requires exactly one of these, the name which specify at the time of routerLink)
  • data (optional, whatever you want to send with the routing that you have to get using routerParams at the receiver end.)

for more info read out here and here.

import {RouteConfig, AuxRoute} from 'angular2/router';
@RouteConfig([
  new AuxRoute({path: '/home', component: HomeCmp})
])
class MyApp {}

I would recommend using CLASS.__bases__ something like this

class A:
   def __init__(self):
        print "I am Class %s"%self.__class__.__name__
        for parentClass in self.__class__.__bases__:
              print "   I am inherited from:",parentClass.__name__
              #parentClass.foo(self) <- call parents function with self as first param
class B(A):pass
class C(B):pass
a,b,c = A(),B(),C()

May this code help you. It works in my case.

$filename = "D:\xampp\htdocs\wordpress/wp-content/uploads/json/2018-10-25.json";
    $fileUrl = "http://localhost/wordpress/wp-content/uploads/json/2018-10-25.json";
    if(!file_exists($filename)):
        $handle = fopen( $filename, 'a' ) or die( 'Cannot open file:  ' . $fileUrl ); //implicitly creates file
        fwrite( $handle, json_encode(array()));
        fclose( $handle );
    endif;
    $response = file_get_contents($filename);
    $tempArray = json_decode($response);
    if(!empty($tempArray)):
        $count = count($tempArray) + 1;
    else:
        $count = 1;
    endif;
    $tempArray[] = array_merge(array("sn." => $count), $data);
    $jsonData = json_encode($tempArray);
    file_put_contents($filename, $jsonData);

Just add negative text intent as so:

input[type=file] {
  text-indent: -120px;
}

Note: Adding a new answer as the publish/unpublish option is moved to different location.

As mentioned in other answers you cannot delete the app. With updated Google Play Console (Beta), the Unpublish option is moved to different location:

Setup -> Advanced Settings -> App Availability

Enable Published / Unpublished accordingly!

Full example:

CREATE TRIGGER [dbo].[trig_020_Original_010_010_Gamechanger]
   ON  [dbo].[T_Original]
   AFTER UPDATE
AS 
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;
    DECLARE @Old_Gamechanger int;
    DECLARE @New_Gamechanger int;

    -- Insert statements for trigger here
    SELECT @Old_Gamechanger = Gamechanger from DELETED;
    SELECT @New_Gamechanger = Gamechanger from INSERTED;

    IF @Old_Gamechanger != @New_Gamechanger

        BEGIN

            INSERT INTO [dbo].T_History(ChangeDate, Reason, Callcenter_ID, Old_Gamechanger, New_Gamechanger)
            SELECT GETDATE(), 'Time for a change', Callcenter_ID, @Old_Gamechanger, @New_Gamechanger
                FROM deleted
            ;

        END

END

I do meet this problem. use ojdbc14.jar and jdk 1.6

InputStream in = new FileInputStream(file);     
cstmt.setBinaryStream(1, in,file.length());  // got AbstractMethodError 

InputStream in = new FileInputStream(file);     
cstmt.setBinaryStream(1, in,(int)file.length());  // no problem.

Stack is much faster. It literally only uses a single instruction on most architectures, in most cases, e.g. on x86:

sub esp, 0x10

(That moves the stack pointer down by 0x10 bytes and thereby "allocates" those bytes for use by a variable.)

Of course, the stack's size is very, very finite, as you will quickly find out if you overuse stack allocation or try to do recursion :-)

Also, there's little reason to optimize the performance of code that doesn't verifiably need it, such as demonstrated by profiling. "Premature optimization" often causes more problems than it's worth.

My rule of thumb: if I know I'm going to need some data at compile-time, and it's under a few hundred bytes in size, I stack-allocate it. Otherwise I heap-allocate it.

Just if any one is interested this worked for me. I have a custom Identity which uses int for a primary key so I overrode the GetUserAsync method

Override GetUserAsync

public override Task<User> GetUserAsync(ClaimsPrincipal principal)
{
    var userId = GetUserId(principal);
    return FindByNameAsync(userId);
}

Get Identity User

var user = await _userManager.GetUserAsync(User);

If you are using a regular Guid primary key you don't need to override GetUserAsync. This is all assuming that you token is configured correctly.

public async Task<string> GenerateTokenAsync(string email)
{
    var user = await _userManager.FindByEmailAsync(email);
    var tokenHandler = new JwtSecurityTokenHandler();
    var key = Encoding.ASCII.GetBytes(_tokenProviderOptions.SecretKey);

    var userRoles = await _userManager.GetRolesAsync(user);
    var roles = userRoles.Select(o => new Claim(ClaimTypes.Role, o));

    var claims = new[]
    {
        new Claim(JwtRegisteredClaimNames.Sub, user.UserName),
        new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString()),
        new Claim(JwtRegisteredClaimNames.Iat, DateTime.UtcNow.ToString(CultureInfo.CurrentCulture)),
        new Claim(JwtRegisteredClaimNames.GivenName, user.FirstName),
        new Claim(JwtRegisteredClaimNames.FamilyName, user.LastName),
        new Claim(JwtRegisteredClaimNames.Email, user.Email),
    }
    .Union(roles);

    var tokenDescriptor = new SecurityTokenDescriptor
    {
        Subject = new ClaimsIdentity(claims),
        Expires = DateTime.UtcNow.AddHours(_tokenProviderOptions.Expires),
        SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature)
    };

    var token = tokenHandler.CreateToken(tokenDescriptor);

    return Task.FromResult(new JwtSecurityTokenHandler().WriteToken(token)).Result;
}

To solve this : error: missing method body, or declare abstract static void main(String[] args);

interface I
{
    int x=20;
    void getValue();
    static void main(String[] args){};//Put curly braces 
}
class InterDemo implements I
{
    public void getValue()
    {
    System.out.println(x);
    }
    public static void main(String[] args)
    {
    InterDemo i=new InterDemo();
    i.getValue();   
    }

}

output : 20

Now we can use static method in interface

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    die("Database selection failed: " . mysqli_error($connection));
}

You got the order of the arguments to mysqli_select_db() backwards. And mysqli_error() requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.

Note also that with mysqli you can specify the DB in mysqli_connect():

$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
  die("Database connection failed: " . mysqli_connect_error();
}

You must use mysqli_connect_error(), not mysqli_error(), to get the error from mysqli_connect(), since the latter requires you to supply a valid connection.

Look into nginx config file to be sure. This command greps for whatever is configured on your Machine:

cat /etc/nginx/sites-enabled/default |grep "root"

on my machine it was :root /usr/share/nginx/www;

document.getElementById('container').innerHTML = lineChartData[array_index]

File file = context.getFilesDir(); 
file.mkdir();
String[] array = filePath.split("/"); 
for(int t = 0; t < array.length - 1; t++) {
    file = new File(file, array[t]); 
    file.mkdir();
}
File f = new File(file,array[array.length- 1]); 
RandomAccessFileOutputStream rvalue = 
    new RandomAccessFileOutputStream(f, append);

I needed to print a binary tree in one of my projects, for that I have prepared a java class TreePrinter, one of the sample output is:

                [+]
               /   \
              /     \
             /       \
            /         \
           /           \
        [*]             \
       /   \             [-]
[speed]     [2]         /   \
                    [45]     [12]

Here is the code for class TreePrinter along with class TextNode. For printing any tree you can just create an equivalent tree with TextNode class.

import java.util.ArrayList;

public class TreePrinter {

    public TreePrinter(){
    }

    public static String TreeString(TextNode root){
        ArrayList layers = new ArrayList();
        ArrayList bottom = new ArrayList();

        FillBottom(bottom, root);  DrawEdges(root);

        int height = GetHeight(root);
        for(int i = 0; i  s.length()) min = s.length();

            if(!n.isEdge) s += "[";
            s += n.text;
            if(!n.isEdge) s += "]";

            layers.set(n.depth, s);
        }

        StringBuilder sb = new StringBuilder();

        for(int i = 0; i  temp = new ArrayList();

            for(int i = 0; i  0) temp.get(i-1).left = x;
                temp.add(x);
            }

            temp.get(count-1).left = n.left;
            n.left.depth = temp.get(count-1).depth+1;
            n.left = temp.get(0);

            DrawEdges(temp.get(count-1).left);
        }
        if(n.right != null){
            int count = n.right.x - (n.x + n.text.length() + 2);
            ArrayList temp = new ArrayList();

            for(int i = 0; i  0) temp.get(i-1).right = x;
                temp.add(x);
            }

            temp.get(count-1).right = n.right;
            n.right.depth = temp.get(count-1).depth+1;
            n.right = temp.get(0);  

            DrawEdges(temp.get(count-1).right);
        }
    }

    private static void FillBottom(ArrayList bottom, TextNode n){
        if(n == null) return;

        FillBottom(bottom, n.left);

        if(!bottom.isEmpty()){            
            int i = bottom.size()-1;
            while(bottom.get(i).isEdge) i--;
            TextNode last = bottom.get(i);

            if(!n.isEdge) n.x = last.x + last.text.length() + 3;
        }
        bottom.add(n);
        FillBottom(bottom, n.right);
    }

    private static boolean isLeaf(TextNode n){
        return (n.left == null && n.right == null);
    }

    private static int GetHeight(TextNode n){
        if(n == null) return 0;

        int l = GetHeight(n.left);
        int r = GetHeight(n.right);

        return Math.max(l, r) + 1;
    }
}


class TextNode {
    public String text;
    public TextNode parent, left, right;
    public boolean isEdge;
    public int x, depth;

    public TextNode(String text){
        this.text = text;
        parent = null; left = null; right = null;
        isEdge = false;
        x = 0; depth = 0;
    }
}

Finally here is a test class for printing given sample:

public class Test {

    public static void main(String[] args){
        TextNode root = new TextNode("+");
        root.left = new TextNode("*");            root.left.parent = root;
        root.right = new TextNode("-");           root.right.parent = root;
        root.left.left = new TextNode("speed");   root.left.left.parent = root.left;
        root.left.right = new TextNode("2");      root.left.right.parent = root.left;
        root.right.left = new TextNode("45");     root.right.left.parent = root.right;
        root.right.right = new TextNode("12");    root.right.right.parent = root.right;

        System.out.println(TreePrinter.TreeString(root));
    }
}

Install xunit.runner.visualstudio package for the test project

As for #2, in my case it magically came to life after replacing

<body>

tag with

<h:body>

After having done several (simpler, to be honest) JSF projects, I couldn't remember of doing anything different setting it up now, and I got this kind of error for the first time. I was making a very basic login page (username, password, user Bean...) and set up everything like usual. The only difference I spotted is tags aforementioned. Maybe someone finds this useful.

I got the same error trying to execute flutter run on a mac. Apparently, in your flutter project, there is a file android/gradlew that is expected to be executable (and it wasn't). So in my case,

chmod a+rx android/gradlew

i used this command and execute the project

I had the same issue.

During the 1st development I used a .csv file (comma as separator) that I've modified a bit before saving it. After saving the commas became semicolon.

On Windows it is dependent on the "Regional and Language Options" customize screen where you find a List separator. This is the char Windows applications expect to be the CSV separator.

When testing from a brand new file I encountered that issue.

I've removed the 'sep' argument in read_csv method before:

df1 = pd.read_csv('myfile.csv', sep=',');

after:

df1 = pd.read_csv('myfile.csv');

That way, the issue disappeared.

void postorder_stack(Node * root){
    stack ms;
    ms.top = -1;
    if(root == NULL) return ;

    Node * temp ;
    push(&ms,root);
    Node * prev = NULL;
    while(!is_empty(ms)){
        temp = peek(ms);
        /* case 1. We are nmoving down the tree. */
        if(prev == NULL || prev->left == temp || prev->right == temp){
             if(temp->left)
                  push(&ms,temp->left);
             else if(temp->right)
                  push(&ms,temp->right);
             else {
                /* If node is leaf node */
                   printf("%d ", temp->value);
                   pop(&ms);
             }
         }
         /* case 2. We are moving up the tree from left child */
         if(temp->left == prev){
              if(temp->right)
                   push(&ms,temp->right);
              else
                   printf("%d ", temp->value);
         }

        /* case 3. We are moving up the tree from right child */
         if(temp->right == prev){
              printf("%d ", temp->value);
              pop(&ms);
         }
         prev = temp;
      }

}

Using a regex

Using a regex, you can clean everything inside <> :

import re

def cleanhtml(raw_html):
  cleanr = re.compile('<.*?>')
  cleantext = re.sub(cleanr, '', raw_html)
  return cleantext

Some HTML texts can also contain entities that are not enclosed in brackets, such as '&nsbm'. If that is the case, then you might want to write the regex as

cleanr = re.compile('<.*?>|&([a-z0-9]+|#[0-9]{1,6}|#x[0-9a-f]{1,6});')

This link contains more details on this.

Using BeautifulSoup

You could also use BeautifulSoup additional package to find out all the raw text.

You will need to explicitly set a parser when calling BeautifulSoup I recommend "lxml" as mentioned in alternative answers (much more robust than the default one (html.parser) (i.e. available without additional install).

from bs4 import BeautifulSoup
cleantext = BeautifulSoup(raw_html, "lxml").text

But it doesn't prevent you from using external libraries, so I recommend the first solution.

EDIT: To use lxml you need to pip install lxml.

You might want to take a look at this example:

public static void main(String[] args) {

    String myTime = "10:30:54";
    SimpleDateFormat sdf = new SimpleDateFormat("hh:mm:ss");
    Date date = null;
    try {
        date = sdf.parse(myTime);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    String formattedTime = sdf.format(date);

    System.out.println(formattedTime);

}

in your hosting.json replace"Url": "http://localhost:80" by"Url": "http://*:80" and you will be able now access to your application by http://your_local_machine_ip:80 for example http://192.168.1.4:80

I hope this will help you

Create table :

create table users (id int,first_name varchar(10),last_name varchar(10));

Insert values into the table :

insert into users (id,first_name,last_name) values(1,'Abhishek','Anand');

I was getting this exact error when loading an HTML file on the browser that was using a json file from the local directory. In my case, I was able to solve this by creating a simple node server that allowed to server static content. I left the code for this at this other answer.

Better to overwrite the whole line otherwise the new line will mix with the old ones if the new line is shorter.

import time, os
for s in ['overwrite!', 'the!', 'whole!', 'line!']:
    print(s.ljust(os.get_terminal_size().columns - 1), end="\r")
    time.sleep(1)

Had to use columns - 1 on Windows.

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

Use gsub:

data1$c <- gsub('_', '-', data1$c)
data1

            a b   c
1  0.34597094 a A-B
2  0.92791908 b A-B
3  0.30168772 c A-B
4  0.46692738 d A-B
5  0.86853784 e A-C
6  0.11447618 f A-C
7  0.36508645 g A-C
8  0.09658292 h A-C
9  0.71661842 i A-C
10 0.20064575 j A-C

Instead of checking for Build.VERSION.SDK_INT >= Build.VERSION_CODES.O as many answers suggest, there is a slightly simpler way -

Add the following line to the application section of AndroidManifest.xml file as explained in the Set Up a Firebase Cloud Messaging Client App on Android doc:

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_channel_id" 
        android:value="@string/default_notification_channel_id" />

Then add a line with a channel name to the values/strings.xml file:

<string name="default_notification_channel_id">default</string>

After that you will be able to use the new version of NotificationCompat.Builder constructor with 2 parameters (since the old constructor with 1 parameter has been deprecated in Android Oreo):

private void sendNotification(String title, String body) {
    Intent i = new Intent(this, MainActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pi = PendingIntent.getActivity(this,
            0 /* Request code */,
            i,
            PendingIntent.FLAG_ONE_SHOT);

    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, 
        getString(R.string.default_notification_channel_id))
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(title)
            .setContentText(body)
            .setAutoCancel(true)
            .setSound(sound)
            .setContentIntent(pi);

    NotificationManager manager = 
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    manager.notify(0, builder.build());
}

Unlike many other languages, R functions don't return multiple objects in the strict sense. The most general way to handle this is to return a list object. So if you have an integer foo and a vector of strings bar in your function, you could create a list that combines these items:

foo <- 12
bar <- c("a", "b", "e")
newList <- list("integer" = foo, "names" = bar)

Then return this list.

After calling your function, you can then access each of these with newList$integer or newList$names.

Other object types might work better for various purposes, but the list object is a good way to get started.

I was facing a problem while calling cross origin resource using ajax from chrome.

I have used node js and local http server to deploy my node js app.

I was getting error response, when I access cross origin resource

I found one solution on that ,

1) I have added below code to my app.js file

res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "X-Requested-With");

2) In my html page called cross origin resource using $.getJSON();

$.getJSON("http://localhost:3000/users", function (data) {
    alert("*******Success*********");
    var response=JSON.stringify(data);
    alert("success="+response);
    document.getElementById("employeeDetails").value=response;
});

A simple definition

• SRC: If a resource can be placed inside the body tag (for image, script, iframe, frame)
• HREF: If a resource cannot be placed inside the body tag and can only be linked (for html, css)

So far best solution that I've made:

function convertHtmlToJQueryObject(html){
    var htmlDOMObject = new DOMParser().parseFromString(html, "text/html");
    return $(htmlDOMObject.documentElement);
}

ev icon next to elements

Within the Firefox Developer Tools' Inspector panel lists all events bound to an element.

First select an element with Ctrl + Shift + C, e.g. Stack Overflow's upvote arrow.

Click on the ev icon to the right of the element, and a dialogue opens:

Click on the pause sign || symbol for the event you want, and this opens the debugger on the line of the handler.

You can now place a breakpoint there as usual in the debugger, by clicking on the left margin of the line.

This is mentioned at: https://developer.mozilla.org/en-US/docs/Tools/Page_Inspector/How_to/Examine_event_listeners

Unfortunately, I couldn't find a way for this to play nicely with prettyfication, it just seems to open at the minified line: How to beautify Javascript and CSS in Firefox / Firebug?

Tested on Firefox 42.

A couple of things:

1. You can't use new as a variable name, it's a reserved word.
2. On input elements, you can just use the value property directly, you don't have to go through getAttribute. The attribute is "reflected" as a property.
3. Same for name.

So:

var inputs, input, newValue, i;

inputs = document.getElementsByTagName('input');
for (i=0; i<inputs.length; i++) {
    input = inputs[i];
    if (input.name == "ans") {   
        newValue = input.value;
        alert(newValue);
    }
}

Try this

// Create a DecimalFormat that fits your requirements
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setGroupingSeparator(',');
symbols.setDecimalSeparator('.');
String pattern = "#,##0.0#";
DecimalFormat decimalFormat = new DecimalFormat(pattern, symbols);
decimalFormat.setParseBigDecimal(true);

// parse the string
BigDecimal bigDecimal = (BigDecimal) decimalFormat.parse("10,692,467,440,017.120");
System.out.println(bigDecimal);

If you are building an application with I18N support you should use DecimalFormatSymbols(Locale)

Also keep in mind that decimalFormat.parse can throw a ParseException so you need to handle it (with try/catch) or throw it and let another part of your program handle it

if you want to display date along with time when you export to Excel then you can use this

xlWorkSheet.Cells(nRow, 3).NumberFormat = "dd/mm/yy h:mm AM/PM"

The solution for my case is:

1. Right click the output window;
2. Check the 'Program Output'

There are little difference in command of adding AND changing DNS-IPs:

To Add:

Syntax:
   netsh interface ipv4 add dnsserver "Network Interface Name" dns.server.ip index=1(for primary)2(for secondary)
Eg:
   netsh interface ipv4 add dnsserver "Ethernet" 8.8.8.8 index=1

• Here, to know "Network Interface Name", type command netsh interface show interface
• 8.8.8.8 is Google's recursive DNS server, use it, if your's not working

To Set/Change: (as OP asked this)

Syntax:
   netsh interface ipv4 set dnsservers "Network Interface Name" static dns.server.ip primary
Eg:
   netsh interface ipv4 set dnsservers "Wi-Fi" static 8.8.4.4 primary
   netsh interface ipv4 set dnsservers "Wi-Fi" dhcp

• Last parameter can be none:disable DNS, both:set for primary and secondary DNS both, primary: for primary DNS only. You can notice here we are not using index-parameter as we did in adding DNS.

• In the place of static you can type dhcp to make DNS setting automatic, but further parameter will not be required.

Note: Tested in windows 8,8.1 & 10.

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

You need to run your code AFTER jQuery finished loading

var script = document.createElement('script'); 
document.head.appendChild(script);    
script.type = 'text/javascript';
script.src = "//ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js";
script.onload = function(){
    // your jQuery code here
} 

or if you're running it in an async function you could use await in the above code

var script = document.createElement('script'); 
document.head.appendChild(script);    
script.type = 'text/javascript';
script.src = "//ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js";
await script.onload
// your jQuery code here

If you want to check first if jQuery already exists in the page, try this

I know that this already has plenty of answers and is a rather old question. But I just came up with this neat one-liner:

JSON.parse(JSON.stringify(raw, ['key', 'value', 'item1', 'item3']))

That returns another object with just the whitelisted attributes. Note that the key and value is included in the list.

untested.cmd

;@echo off
;Findstr -rbv ; %0 | powershell -c - 
;goto:sCode

set-location "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"

Hibernate is not going to make it easy for you to do what you are trying to do. From the Hibernate documentation:

Note that when using referencedColumnName to a non primary key column, the associated class has to be Serializable. Also note that the referencedColumnName to a non primary key column has to be mapped to a property having a single column (other cases might not work). (emphasis added)

So if you are unwilling to make AnEmbeddableObject the Identifier for Bar then Hibernate is not going to lazily, automatically retrieve Bar for you. You can, of course, still use HQL to write queries that join on AnEmbeddableObject, but you lose automatic fetching and life cycle maintenance if you insist on using a multi-column non-primary key for Bar.

Try to create script with ADD command and specification of working directory Like this("script" is the name of script and /root/script.sh is where you want it in the container, it can be different path:

ADD script.sh /root/script.sh

In this case ADD has to come before CMD, if you have one BTW it's cool way to import scripts to any location in container from host machine

In CMD place [./script]

It should automatically execute your script

You can also specify WORKDIR as /root, then you'l be automatically placed in root, upon starting a container

With two capturing groups would have been also possible; I would have also included two dashes, as additional left and right boundaries, before and after the digits, and the modified expression would have looked like:

(.*name=".+_)\d+(_[^"]+".*)

const regex = /(.*name=".+_)\d+(_[^"]+".*)/g;_x000D_
const str = `some_data_before name="some_text_0_some_text" and then some_data after`;_x000D_
const subst = `$1!NEW_ID!$2`;_x000D_
const result = str.replace(regex, subst);_x000D_
console.log(result);

If you wish to explore/simplify/modify the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.

RegEx Circuit

jex.im visualizes regular expressions:

I had same issue in Android Studio 3. (the project was open) so I closed the current project and the IDE automatically prompted to download the latest components. once its done everything was working correctly.

I have the exact same problem, and here is the solution I make use of now: (Note, this seems ideal to me because it keeps the files closely tied to the SinglePageApplication React app, that loads from Amazon S3. So, it's like storing on S3, and in an application, that knows where it is in S3, relatively speaking.

Steps

3 steps:

1. Make use of file saver in project: npmjs/package/file-saver (npm install file-saver or something)
2. Place the file in your project You say it's in the components folder. Well, chances are if you've got web-pack it's going to try and minify it.(someone please pinpoint what webpack would do with an asset file in components folder), and so I don't think it's what you'd want. So, I suggest to place the asset into the public folder, under a resource or an asset name. Webpack doesn't touch the public folder and index.html and your resources get copied over in production build as is, where you may refer them as shown in next step.
3. Refer to the file in your project Sample code:

   import FileSaver from 'file-saver';
   FileSaver.saveAs(
       process.env.PUBLIC_URL + "/resource/file.anyType",
       "fileNameYouWishCustomerToDownLoadAs.anyType");

• I also try Link component of react-router react-router-docs/Link. The zip file would download, and somehow would unzip properly. Generally, links have blue color, to inherit parent color scheme, simply add a prop like: style={color: inherit} or simply assign a class of your CSS library like button button-primary or something if you're Bootstrappin'

1) First go to Server Explorer in Visual Studio, check if the ".mdf" Data Connections for this project are connected, if so, right click and delete.

2 )Go to Solution Explorer, click show All Files icon.

3) Go to App_Data, right click and delete all ".mdf" files for this project.

4) Delete Migrations folder by right click and delete.

5) Go to SQL Server Management Studio, make sure the DB for this project is not there, otherwise delete it.

6) Go to Package Manager Console in Visual Studio and type:

1. Enable-Migrations -Force
2. Add-Migration init
3. Update-Database

7) Run your application

Note: In step 6 part 3, if you get an error "Cannot attach the file...", it is possibly because you didn't delete the database files completely in SQL Server.

In build.gradle change minSdkVersion 13 to minSdkVersion 8 Thats all you need to do. I solved my problem by only doing this.

defaultConfig {
    applicationId "com.example.sabrim.sbrtest"
    minSdkVersion 8
    targetSdkVersion 20
    versionCode 1
    versionName "1.0"
}

In your action method, return Json(object) to return JSON to your page.

public ActionResult SomeActionMethod() {
  return Json(new {foo="bar", baz="Blech"});
}

Then just call the action method using Ajax. You could use one of the helper methods from the ViewPage such as

<%= Ajax.ActionLink("SomeActionMethod", new AjaxOptions {OnSuccess="somemethod"}) %>

SomeMethod would be a javascript method that then evaluates the Json object returned.

If you want to return a plain string, you can just use the ContentResult:

public ActionResult SomeActionMethod() {
    return Content("hello world!");
}

ContentResult by default returns a text/plain as its contentType.
This is overloadable so you can also do:

return Content("<xml>This is poorly formatted xml.</xml>", "text/xml");

Assuming your objective is to develop and test your xpath queries for screen maps. Then either use Chrome's developer tools. This allows you to run the xpath query to show the matches. Or in Firefox >9 you can do the same thing with the Web Developer Tools console. In earlier version use x-path-finder or Firebug.

Most browsers are now implementing high resolution timing in performance.now(). It's superior to new Date() for performance testing because it operates independently from the system clock.

Usage

var start = performance.now();

// code being timed...

var duration = performance.now() - start;

A simpler approach to this

At the beginning of column B, type

=UNIQUE(A:A)

Then in column C, use

=COUNTIF(A:A, B1)

and copy them in all row column C.

Edit: If that doesn't work for you, try using semicolon instead of comma:

=COUNTIF(A:A; B1)

You could use the JavaScriptSerializer class (add reference to System.Web.Extensions):

using System.Web.Script.Serialization;

var json = new JavaScriptSerializer().Serialize(obj);

A full example:

using System;
using System.Web.Script.Serialization;

public class MyDate
{
    public int year;
    public int month;
    public int day;
}

public class Lad
{
    public string firstName;
    public string lastName;
    public MyDate dateOfBirth;
}

class Program
{
    static void Main()
    {
        var obj = new Lad
        {
            firstName = "Markoff",
            lastName = "Chaney",
            dateOfBirth = new MyDate
            {
                year = 1901,
                month = 4,
                day = 30
            }
        };
        var json = new JavaScriptSerializer().Serialize(obj);
        Console.WriteLine(json);
    }
}

Two ways come to mind:

• Using a command-line tool like the popular ffmpeg, however you will almost always need an own server (or a very nice server administrator / hosting company) to get that

• Using the "screenshoot" plugin for the LongTail Video player that allows the creation of manual screenshots that are then sent to a server-side script.

To access properties and methods of a parent class use the base keyword. So in your child class LoadData() method you would do this:

public class Child : Parent 
{
    public void LoadData() 
    {
        base.MyMethod(); // call method of parent class
        base.CurrentRow = 1; // set property of parent class
        // other stuff...
    }
}

Note that you would also have to change the access modifier of your parent MyMethod() to at least protected for the child class to access it.

$(".excel").click(function () {
    var t = $(this).closest(".tblGrid").attr("id");
    window.frames["Iframe" + t].document.location.href = pagename + "?tbl=" + t;
});

this is what i use, no jquery needed for this. in this particular scenario for each table i have with an excel export icon this forces the iframe attached to that table to load the same page with a variable in the Query String that the page looks for, and if found response writes out a stream with an excel mimetype and includes the data for that table.

Shubham's answer explains very well. This answer is addition to it as per to avoid some pitfalls and refactoring to a more readable syntax

Pitfall : There is common misconception in rendering array of objects especially if there is an update or delete action performed on data. Use case would be like deleting an item from table row. Sometimes when row which is expected to be deleted, does not get deleted and instead other row gets deleted.

To avoid this, use key prop in root element which is looped over in JSX tree of .map(). Also adding React's Fragment will avoid adding another element in between of ul and li when rendered via calling method.

state = {
    userData: [
        { id: '1', name: 'Joe', user_type: 'Developer' },
        { id: '2', name: 'Hill', user_type: 'Designer' }
    ]
};

deleteUser = id => {
    // delete operation to remove item
};

renderItems = () => {
    const data = this.state.userData;

    const mapRows = data.map((item, index) => (
        <Fragment key={item.id}>
            <li>
                {/* Passing unique value to 'key' prop, eases process for virtual DOM to remove specific element and update HTML tree  */}
                <span>Name : {item.name}</span>
                <span>User Type: {item.user_type}</span>
                <button onClick={() => this.deleteUser(item.id)}>
                    Delete User
                </button>
            </li>
        </Fragment>
    ));
    return mapRows;
};

render() {
    return <ul>{this.renderItems()}</ul>;
}

Important : Decision to use which value should we pass to key prop also matters as common way is to use index parameter provided by .map().

TLDR; But there's a drawback to it and avoid it as much as possible and use any unique id from data which is being iterated such as item.id. There's a good article on this - https://medium.com/@robinpokorny/index-as-a-key-is-an-anti-pattern-e0349aece318

Here's a solution that I use for the fish shell. Tested on Mac OS X 10.11.5, fish 2.3.0 and git 2.8.3.

function git_clean_branches
  set base_branch develop

  # work from our base branch
  git checkout $base_branch

  # remove local tracking branches where the remote branch is gone
  git fetch -p

  # find all local branches that have been merged into the base branch
  # and delete any without a corresponding remote branch
  set local
  for f in (git branch --merged $base_branch | grep -v "\(master\|$base_branch\|\*\)" | awk '/\s*\w*\s*/ {print $1}')
    set local $local $f
  end

  set remote
  for f in (git branch -r | xargs basename)
    set remote $remote $f
  end

  for f in $local
    echo $remote | grep --quiet "\s$f\s"
    if [ $status -gt 0 ]
      git branch -d $f
    end
  end
end

A few notes:

Make sure to set the correct base_branch. In this case I use develop as the base branch, but it could be anything.

This part is very important: grep -v "\(master\|$base_branch\|\*\)". It ensures that you don't delete master or your base branch.

I use git branch -d <branch> as an extra precaution, so as to not delete any branch that has not been fully merged with upstream or current HEAD.

An easy way to test is to replace git branch -d $f with echo "will delete $f".

I suppose I should also add: USE AT YOUR OWN RISK!

Edit Jan 2021: The React Native docs currently recommend React Native WebView:

<WebView
    originWhitelist={['*']}
    source={{ html: '<p>Here I am</p>' }}
/>

https://github.com/react-native-webview/react-native-webview

Edit March 2017: the html prop has been deprecated. Use source instead:

<WebView source={{html: '<p>Here I am</p>'}} />

https://facebook.github.io/react-native/docs/webview.html#html

Thanks to Justin for pointing this out.

Edit Feb 2017: the PR was accepted a while back, so to render HTML in React Native, simply:

<WebView html={'<p>Here I am</p>'} />

Original Answer:

I don't think this is currently possible. The behavior you're seeing is expected, since the Text component only outputs... well, text. You need another component that outputs HTML - and that's the WebView.

Unfortunately right now there's no way of just directly setting the HTML on this component:

https://github.com/facebook/react-native/issues/506

However I've just created this PR which implements a basic version of this feature so hopefully it'll land in some form soonish.

Little correction at Line 3

HTMLParser.HTMLParser.__init__(self)

it should be

HTMLParser.__init__(self)

The following worked for me though

import urllib2 

from HTMLParser import HTMLParser  

class MyHTMLParser(HTMLParser):

  def __init__(self):
    HTMLParser.__init__(self)
    self.recording = 0 
    self.data = []
  def handle_starttag(self, tag, attrs):
    if tag == 'required_tag':
      for name, value in attrs:
        if name == 'somename' and value == 'somevale':
          print name, value
          print "Encountered the beginning of a %s tag" % tag 
          self.recording = 1 


  def handle_endtag(self, tag):
    if tag == 'required_tag':
      self.recording -=1 
      print "Encountered the end of a %s tag" % tag 

  def handle_data(self, data):
    if self.recording:
      self.data.append(data)

 p = MyHTMLParser()
 f = urllib2.urlopen('http://www.someurl.com')
 html = f.read()
 p.feed(html)
 print p.data
 p.close()

You can use the window.innerWidth and window.innerHeight properties.

git status displays "both modified" next to files that have conflicts instead of "modified" or "new file", etc

In a pure Javascript way, you can submit the form after preventing default.

This is because HTMLFormElement.submit() never calls the onSubmit(). So we're relying on that specification oddity to submit the form as if it doesn't have a custom onsubmit handler here.

var submitHandler = (event) => {
  event.preventDefault()
  console.log('You should only see this once')
  document.getElementById('formId').submit()
}

See this fiddle for a synchronous request.

Waiting for an async request to finish up is just as easy:

var submitHandler = (event) => {
  event.preventDefault()
  console.log('before')
  setTimeout(function() {
    console.log('done')
    document.getElementById('formId').submit()
  }, 1400);
  console.log('after')
}

You can check out my fiddle for an example of an asynchronous request.

And if you are down with promises:

var submitHandler = (event) => {
  event.preventDefault()
  console.log('Before')
    new Promise((res, rej) => {
      setTimeout(function() {
        console.log('done')
        res()
      }, 1400);
    }).then(() => {
      document.getElementById('bob').submit()
    })
  console.log('After')
}

And here's that request.

You can also add the --cached flag to auco's answer to maintain local .DS_store files, as Edward Newell mentioned in his original answer. The modified command looks like this: find . -name .DS_Store -print0 | xargs -0 git rm --cached --ignore-unmatch ..cheers and thanks!

Even though this is an old question, I've just come across the problem and solved it differently from the given answers. Maybe it could be helpful to others.

I noticed that even though my XML files looked like:

<tag>
 <subTag>content with newline.\r\nto display</subTag>
</tag>

When it was read into my C# code the string had double backslashes.

\\r\\n

To fix this I wrote a ValueConverter to strip the extra backslash.

public class XmlStringConverter : IValueConverter
{
    public object Convert(
        object value,
        Type targetType,
        object parameter,
        CultureInfo culture)
    {
        string valueAsString = value as string;
        if (string.IsNullOrEmpty(valueAsString))
        {
            return value;
        }

        valueAsString = valueAsString.Replace("\\r\\n", "\r\n");
        return valueAsString;
    }

    public object ConvertBack(
        object value,
        Type targetType,
        object parameter,
        CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

You might be after something that the scrollTo plugin from Ariel Flesler does really well.

http://demos.flesler.com/jquery/scrollTo/

    try 
    {  
      String datestr="06/27/2007";
      DateFormat formatter; 
      Date date; 
      formatter = new SimpleDateFormat("MM/dd/yyyy");
      date = (Date)formatter.parse(datestr);  
    } 
    catch (Exception e)
    {}

month is MM, minutes is mm..

In addition to the comprehensive answer already posted sometimes it is useful to be able to access the execution plan programatically to extract information. Example code for this is below.

Get the file register.py from this gist. Save it on your C drive or D drive, go to CMD to run it with:

'python register.py'

Then you will be able to install it.

You can create a string[] (string array) that contains your string like :

string someString = "something";
string[] stringArray = new string[]{ someString };

The variable stringArray will now have a length of 1 and contain someString.

This is a twist on 'exans' answer that uses Named Aggregations. It's the same but with argument unpacking which allows you to still pass in a dictionary to the agg function.

The named aggs are a nice feature, but at first glance might seem hard to write programmatically since they use keywords, but it's actually simple with argument/keyword unpacking.

animals = pd.DataFrame({'kind': ['cat', 'dog', 'cat', 'dog'],
                         'height': [9.1, 6.0, 9.5, 34.0],
                         'weight': [7.9, 7.5, 9.9, 198.0]})
 
agg_dict = {
    "min_height": pd.NamedAgg(column='height', aggfunc='min'),
    "max_height": pd.NamedAgg(column='height', aggfunc='max'),
    "average_weight": pd.NamedAgg(column='weight', aggfunc=np.mean)
}

animals.groupby("kind").agg(**agg_dict)

The Result

      min_height  max_height  average_weight
kind                                        
cat          9.1         9.5            8.90
dog          6.0        34.0          102.75

Use the second parameter of json_decode to make it return an array:

The header() function has a parameter for status code. If you specify it, the server will take care of it from there.

display is not an attribute - it's a CSS property. You need to access the style object for this:

document.getElementById('classRight').style.display = 'none';

Also another important note. You have to set android.permission.ACCESS_NETWORK_STATE in your AndroidManifest.xml for this to work.

_ how could I have found myself the information I needed in the online documentation?

You just have to read the documentation the the classes properly enough and you'll find all answers you are looking for. Check out the documentation on ConnectivityManager. The description tells you what to do.

I had some issues importing additional libraries, after trying to resolve the problem, by understanding PYTHONPATH, Interpreter, and Grammar I found that I did everything write but the problems continue. After that, I just add a new empty line in the files that had the import errors and saved them and the error was resolved.

It may not be obvious how to break a shell command into a sequence of arguments, especially in complex cases. shlex.split() can do the correct tokenization for args (I'm using Blender's example of the call):

import shlex
from subprocess import Popen, PIPE
command = shlex.split('swfdump /tmp/filename.swf/ -d')
process = Popen(command, stdout=PIPE, stderr=PIPE)
stdout, stderr = process.communicate()

Sadly, many JSON C++ libraries have APIs that are non trivial to use, while JSON was intended to be easy to use.

So I tried jsoncpp from the gSOAP tools on the JSON doc shown in one of the answers above and this is the code generated with jsoncpp to construct a JSON object in C++ which is then written in JSON format to std::cout:

value x(ctx);
x["appDesc"]["description"] = "SomeDescription";
x["appDesc"]["message"] = "SomeMessage";
x["appName"]["description"] = "Home";
x["appName"]["message"] = "Welcome";
x["appName"]["imp"][0] = "awesome";
x["appName"]["imp"][1] = "best";
x["appName"]["imp"][2] = "good";
std::cout << x << std::endl;

and this is the code generated by jsoncpp to parse JSON from std::cin and extract its values (replace USE_VAL as needed):

value x(ctx);
std::cin >> x;
if (x.soap->error)
  exit(EXIT_FAILURE); // error parsing JSON
#define USE_VAL(path, val) std::cout << path << " = " << val << std::endl
if (x.has("appDesc"))
{
  if (x["appDesc"].has("description"))
    USE_VAL("$.appDesc.description", x["appDesc"]["description"]);
  if (x["appDesc"].has("message"))
    USE_VAL("$.appDesc.message", x["appDesc"]["message"]);
}
if (x.has("appName"))
{
  if (x["appName"].has("description"))
    USE_VAL("$.appName.description", x["appName"]["description"]);
  if (x["appName"].has("message"))
    USE_VAL("$.appName.message", x["appName"]["message"]);
  if (x["appName"].has("imp"))
  {
    for (int i2 = 0; i2 < x["appName"]["imp"].size(); i2++)
      USE_VAL("$.appName.imp[]", x["appName"]["imp"][i2]);
  }
}

This code uses the JSON C++ API of gSOAP 2.8.28. I don't expect people to change libraries, but I think this comparison helps to put JSON C++ libraries in perspective.

the approach you took is good. Just Implementation may need to be better. For instance ReturningValues should be well defined and Its better if you can make ReturningValues as immutable.

// this approach is better
public static ReturningValues myMethod() {
    ReturningValues rv = new ReturningValues("value", 12);
    return rv;
}


public final class ReturningValues {
    private final String value;
    private final int index;


    public ReturningValues(String value, int index) {
      this.value = value;
      this.index = index;
     }

} 

Or if you have lots of key value pairs you can use HashMap then

public static Map<String,Object> myMethod() {
  Map<String,Object> map = new HashMap<String,Object>();
  map.put(VALUE, "value");
  map.put(INDEX, 12);
  return Collections.unmodifiableMap(map); // try to use this 
}

Actually, whenever I need to run a command on a remote machine that's complicated, I like to put the command in a script on the destination machine, and just run that script using ssh.

For example:

# simple_script.sh (located on remote server)

#!/bin/bash

cat /var/log/messages | grep <some value> | awk -F " " '{print $8}'

And then I just run this command on the source machine:

ssh user@ip "/path/to/simple_script.sh"

Here's a really basic way to do it:

window.onscroll = function () { window.scrollTo(0, 0); };

It's kind of jumpy in IE6.

#include <iostream>
#include <string>
using namespace std;

int main()
{
    cout << stod("  99.999  ") << endl;
}

Output: 99.999 (which is double, whitespace was automatically stripped)

Since C++11 converting string to floating-point values (like double) is available with functions:
stof - convert str to a float
stod - convert str to a double
stold - convert str to a long double

I want a function that returns 0 when the string is not numerical.

You can add try catch statement when stod throws an exception.

One approach is to 'walk the dates' from start to finish in conjunction with a case expression which checks if the day is not a Saturday or a Sunday and flagging it(1 for weekday, 0 for weekend). And in the end just sum flags(it would be equal to the count of 1-flags as the other flag is 0) to give you the number of weekdays.

You can use a GetNums(startNumber,endNumber) type of utility function which generates a series of numbers for 'looping' from start date to end date. Refer http://tsql.solidq.com/SourceCodes/GetNums.txt for an implementation. The logic can also be extended to cater for holidays(say if you have a holidays table)

declare @date1 as datetime = '19900101'
declare @date2 as datetime = '19900120'

select  sum(case when DATENAME(DW,currentDate) not in ('Saturday', 'Sunday') then 1 else 0 end) as noOfWorkDays
from dbo.GetNums(0,DATEDIFF(day,@date1, @date2)-1) as Num
cross apply (select DATEADD(day,n,@date1)) as Dates(currentDate)

In a for-in-loop the running variable holds the property name, not the property value.

for (var counter in jsonData.counters) {
    console.log(jsonData.counters[counter].counter_name);
}

But as counters is an Array, you have to use a normal for-loop:

for (var i=0; i<jsonData.counters.length; i++) {
    var counter = jsonData.counters[i];
    console.log(counter.counter_name);
}

This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.

The onload event does not always work on IE7/8 in <head> ... </head>

You can force it by adding an onload script at the end of your page before the tag as below.

  <script>
    window.onload();
  </script>
</body>

Elaborating a bit more on Taylor Gautier's reply (sorry, I dont have enough reputation to add a comment), I'd reply to Dean Richardson on how to do what he wanted, without any additional JS code. Pure CSS.

You would replace his .btn with the following:

<a class="btn showdetails" data-toggle="collapse" data-target="#viewdetails"></a>

And add a small CSS for when the content is displayed:

.in.collapse+a.btn.showdetails:before { 
    content:'Hide details «';
}
.collapse+a.btn.showdetails:before { 
    content:'Show details »'; 
}

Here is his modified example

Have you tried strtol()?

strtol - convert string to a long integer

Example:

const char *hexstring = "abcdef0";
int number = (int)strtol(hexstring, NULL, 16);

In case the string representation of the number begins with a 0x prefix, one must should use 0 as base:

const char *hexstring = "0xabcdef0";
int number = (int)strtol(hexstring, NULL, 0);

(It's as well possible to specify an explicit base such as 16, but I wouldn't recommend introducing redundancy.)

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

Look in the manual http://www.php.net/manual/en/mysqli.query.php

<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

/* check connection */
if ($mysqli->connect_errno) {
    printf("Connect failed: %s\n", $mysqli->connect_error);
    exit();
}

/* Create table doesn't return a resultset */
if ($mysqli->query("CREATE TEMPORARY TABLE myCity LIKE City") === TRUE) {
    printf("Table myCity successfully created.\n");
}

/* Select queries return a resultset */
if ($result = $mysqli->query("SELECT Name FROM City LIMIT 10")) {
    printf("Select returned %d rows.\n", $result->num_rows);

    /* free result set */
    $result->close();
}

/* If we have to retrieve large amount of data we use MYSQLI_USE_RESULT */
if ($result = $mysqli->query("SELECT * FROM City", MYSQLI_USE_RESULT)) {

    /* Note, that we can't execute any functions which interact with the
       server until result set was closed. All calls will return an
       'out of sync' error */
    if (!$mysqli->query("SET @a:='this will not work'")) {
        printf("Error: %s\n", $mysqli->error);
    }
    $result->close();
}

$mysqli->close();
?>

I'm not sure what server side technology you are using but try using a json array. A couple of options for you to try:

{
  "address": "colombo",
  "username": "hesh",
  "password": "123",
  "registetedDate": "2015-4-3",
  "firstname": "hesh",
  "contactNo": "07762",
  "accountNo": "16161",
  "lastName": "jay"
 },
[
   1436517454492,
   1436517476993
]

If that doesn't work you may also try:

{
  freelancer: {
  "address": "colombo",
  "username": "hesh",
  "password": "123",
  "registetedDate": "2015-4-3",
  "firstname": "hesh",
  "contactNo": "07762",
  "accountNo": "16161",
  "lastName": "jay"
 },

    ]
}

You could try NumberFormatter.

$(this).format({format:"#,###.00", locale:"us"});

It also supports different locales, including of course US.

Here's a very simplified example of how to use it:

<html>
    <head>
        <script type="text/javascript" src="jquery.js"></script>
        <script type="text/javascript" src="jquery.numberformatter.js"></script>
        <script>
        $(document).ready(function() {
            $(".numbers").each(function() {
                $(this).format({format:"#,###", locale:"us"});
            });
        });
        </script>
    </head>
    <body>
        <div class="numbers">1000</div>
        <div class="numbers">2000000</div>
    </body>
</html>

Output:

1,000
2,000,000

While you have a return value in checkform, it isn't being used anywhere - try using onclick="return checkform()" instead.

You may want to considering replacing this method with onsubmit="return checkform()" in the form tag instead, though both will work for clicking the button.

This eclipse documentation has details on the markups in .project file: The project description file

It describes the .project file as:

When a project is created in the workspace, a project description file is automatically generated that describes the project. The purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace. This file is always called ".project"

While this doesn't directly answer the question, there is great book available for free which will help you learn the basics called ProGit. If you would prefer the dead-wood version to a collection of bits you can purchase it from Amazon.

When you click your button you can have it call:

super.onBackPressed();

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

You were right to look at using a set, we just need to dig in a little deeper to get your method to work.

First, the example code:

test_1 = {"foo": "bar", "FOO": "BAR"}
test_2 = {"foo": "bar", "f00": "b@r"}

We can see right now that both dictionaries contain a similar key/value pair:

{"foo": "bar", ...}

Each dictionary also contains a completely different key value pair. But how do we detect the difference? Dictionaries don't support that. Instead, you'll want to use a set.

Here is how to turn each dictionary into a set we can use:

set_1 = set(test_1.items())
set_2 = set(test_2.items())

This returns a set containing a series of tuples. Each tuple represents one key/value pair from your dictionary.

Now, to find the difference between set_1 and set_2:

print set_1 - set_2
>>> {('FOO', 'BAR')}

Want a dictionary back? Easy, just:

dict(set_1 - set_2)
>>> {'FOO': 'BAR'}

resize2fs Command will not work for all file systems.

Please confirm the file system of your instance using below command.

Please follow the procedure to expand volume by following the steps mentioned in Amazon official document for different file systems.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html

Default file system in Centos is xfs, use the following command for xfs file system to increase partition size.

sudo xfs_growfs -d /

then "df -h" to check.

Interesting info about MSCorlib:

• The .NET 2.0 assembly will reference and use the 2.0 mscorlib.The .NET 1.1 assembly will reference the 1.1 mscorlib but will use the 2.0 mscorlib at runtime (due to hard-coded version redirects in theruntime itself)
• In GAC there is only one version of mscorlib, you dont find 1.1 version on GAC even if you have 1.1 framework installed on your machine. It would be good if somebody can explain why MSCorlib 2.0 alone is in GAC whereas 1.x version live inside framework folder
• Is it possible to force a different runtime to be loaded by the application by making a config setting in your app / web.config? you won’t be able to choose the CLR version by settings in the ConfigurationFile – at that point, a CLR will already be running, and there can only be one per process. Immediately after the CLR is chosen the MSCorlib appropriate for that CLR is loaded.

This is an old question, but since it still comes up at the top of my results in Google, here's another way.

import pandas as pd
import numpy as np

df = pd.DataFrame({'col1':list("abc"),'col2':range(3)},index = range(3))

Say you want to replicate the rows where col1="b".

reps = [3 if val=="b" else 1 for val in df.col1]
df.loc[np.repeat(df.index.values, reps)]

You could replace the 3 if val=="b" else 1 in the list interpretation with another function that could return 3 if val=="b" or 4 if val=="c" and so on, so it's pretty flexible.

As of MySql 5.1 version reference

BIT(M) =  approximately (M+7)/8 bytes, 
BIT(1) =  (1+7)/8 = 1 bytes (8 bits)

=========================================================================

TINYINT(1) take 8 bits.

Most likely these classes are already defined by Bootstrap, make sure that your CSS file that you want to override the classes with is called AFTER the Bootstrap CSS.

<link rel="stylesheet" href="css/bootstrap.css" /> <!-- Call Bootstrap first -->
<link rel="stylesheet" href="css/bootstrap-override.css" /> <!-- Call override CSS second -->

Otherwise, you can put !important at the end of your CSS like this: color:#ffffff!important; but I would advise against using !important at all costs.

You could just use normal Python argument passing syntax to specify your crontab. For example, suppose we define an Event class as below:

from datetime import datetime, timedelta
import time

# Some utility classes / functions first
class AllMatch(set):
    """Universal set - match everything"""
    def __contains__(self, item): return True

allMatch = AllMatch()

def conv_to_set(obj):  # Allow single integer to be provided
    if isinstance(obj, (int,long)):
        return set([obj])  # Single item
    if not isinstance(obj, set):
        obj = set(obj)
    return obj

# The actual Event class
class Event(object):
    def __init__(self, action, min=allMatch, hour=allMatch, 
                       day=allMatch, month=allMatch, dow=allMatch, 
                       args=(), kwargs={}):
        self.mins = conv_to_set(min)
        self.hours= conv_to_set(hour)
        self.days = conv_to_set(day)
        self.months = conv_to_set(month)
        self.dow = conv_to_set(dow)
        self.action = action
        self.args = args
        self.kwargs = kwargs

    def matchtime(self, t):
        """Return True if this event should trigger at the specified datetime"""
        return ((t.minute     in self.mins) and
                (t.hour       in self.hours) and
                (t.day        in self.days) and
                (t.month      in self.months) and
                (t.weekday()  in self.dow))

    def check(self, t):
        if self.matchtime(t):
            self.action(*self.args, **self.kwargs)

(Note: Not thoroughly tested)

Then your CronTab can be specified in normal python syntax as:

c = CronTab(
  Event(perform_backup, 0, 2, dow=6 ),
  Event(purge_temps, 0, range(9,18,2), dow=range(0,5))
)

This way you get the full power of Python's argument mechanics (mixing positional and keyword args, and can use symbolic names for names of weeks and months)

The CronTab class would be defined as simply sleeping in minute increments, and calling check() on each event. (There are probably some subtleties with daylight savings time / timezones to be wary of though). Here's a quick implementation:

class CronTab(object):
    def __init__(self, *events):
        self.events = events

    def run(self):
        t=datetime(*datetime.now().timetuple()[:5])
        while 1:
            for e in self.events:
                e.check(t)

            t += timedelta(minutes=1)
            while datetime.now() < t:
                time.sleep((t - datetime.now()).seconds)

A few things to note: Python's weekdays / months are zero indexed (unlike cron), and that range excludes the last element, hence syntax like "1-5" becomes range(0,5) - ie [0,1,2,3,4]. If you prefer cron syntax, parsing it shouldn't be too difficult however.

I had the same problem.

Make sure that you build the APK file with the same device that generated the hashkey which is stored on in the Facebook developers section.

What sort of rounding behavior do you want? Do you 2.67 to turn into 3, or 2. If you want to use rounding, try this:

s = '234.67'
i = int(round(float(s)))

Otherwise, just do:

s = '234.67'
i = int(float(s))

I have just wrote a reusable method for that, there is no answer here with reusable method so why not to share...

    try
    {
        using (SqlCommand cmd = new SqlCommand(query, connection))
        {   // for cases where no parameters needed
            if (parameters != null)
            {
                cmd.Parameters.AddRange(parameters.ToArray());
            }

            connection.Open();
            int result = cmd.ExecuteNonQuery();
            return result;
        }
    }
    catch (Exception ex)
    {
        AddEventToEventLogTable("ERROR in DAL.DataBase.ParametersCommand() method: " + ex.Message, 1);
        return 0;
        throw;
    }

    finally
    {
        CloseConnection(ref connection);
    }
}

private static void CloseConnection(ref SqlConnection conn)
{
    if (conn.State != ConnectionState.Closed)
    {
        conn.Close();
        conn.Dispose();
    }
}

To set headers in an Axios POST request, pass the third object to the axios.post() call.

const token = '..your token..'

axios.post(url, {
  //...data
}, {
  headers: {
    'Authorization': `Basic ${token}` 
  }
})

To set headers in an Axios GET request, pass a second object to the axios.get() call.

const token = '..your token..' 

axios.get(url, {
  headers: {
    'Authorization': `Basic ${token}`
  }
})

Yes you only need $() when you're using jQuery. If you want jQuery's help to do DOM things just keep this in mind.

$(this)[0] === this

Basically every time you get a set of elements back jQuery turns it into a jQuery object. If you know you only have one result, it's going to be in the first element.

$("#myDiv")[0] === document.getElementById("myDiv");

And so on...

Since iOS 8 came out, this problem does not exist any more. The scroll event is now fired smoothly in iOS Safari as well.

So, if you register the scroll event handler and check window.pageYOffset inside that event handler, everything works just fine.

I was also facing the same issue, then i tried restarting my system after every change and it worked for me:

1. Uninstall Apache2.4 in cmd prompt (run administrator) with the command: httpd -k uninstall.
2. Restart the system.
3. open cmd prompt (run administrator) with the command: httpd -k install.
4. Then httpd -k install.

Hope you find useful.

Probably can add a few more line to increase the timeout period to upstream. The examples below sets the timeout to 300 seconds :

proxy_read_timeout          300;

        System.out.println(word);
    }

}

thanks to @??s???? K and Terry ... it helps me a lot and works perfectly

From Activity you send data with intent as:

Bundle bundle = new Bundle(); 
bundle.putString("edttext", "From Activity"); 
// set Fragmentclass Arguments
Fragmentclass fragobj = new Fragmentclass();
fragobj.setArguments(bundle);

and in Fragment onCreateView method:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // get arguments
    String strtext = getArguments().getString("edttext");    
    return inflater.inflate(R.layout.fragment, container, false);
}

Try gzipping some data through the gzip libary like this...

import gzip
content = "Lots of content here"
f = gzip.open('Onlyfinnaly.log.gz', 'wb')
f.write(content)
f.close()

... then run your code as posted ...

import gzip
f=gzip.open('Onlyfinnaly.log.gz','rb')
file_content=f.read()
print file_content

This method worked for me as for some reason the gzip library fails to read some files.

Not really, you have to assign a variable. So

    var bar = Stuff.Elements.Foo;
    bar.Name = "Bob Dylan";
    bar.Age = 68;
    bar.Location = "On Tour";
    bar.IsCool = True;

Or in C# 3.0:

    var bar = Stuff.Elements.Foo
    {
        Name = "Bob Dylan",
        Age = 68,
        Location = "On Tour",
        IsCool = True
    };

This is called programming to interface. This will be helpful in case if you wish to move to some other implementation of List in the future. If you want some methods in ArrayList then you would need to program to the implementation that is ArrayList a = new ArrayList().

Actually all answers are wrong

Easy: foo.[0]filename

I am stuck on the same problem. Setting alpha is not what I want.

UIButton has "background image" and "background color". For image, UIButton has a property as

@property (nonatomic) BOOL adjustsImageWhenDisabled

And background image is drawn lighter when the button is disabled. For background color, setting alpha, Ravin's solution, works fine.

First, you have to check whether you have unchecked "disabled adjusts image" box under Utilities-Attributes.
Then, check the background color for this button.

(Hope it's helpful. This is an old post; things might have changed in Xcode).

There is a bug reported for Pillow here, which indicates that libjpeg and zlib are now required as of Pillow 3.0.0.

The installation instructions for Pillow on Linux give advice of how to install these packages. Note that not all of the following packages may be missing on your machine (comments suggest that only libjpeg8-dev is actually missing).

pip / PyPi (Pillow>3.4.2)

The latest releases of Pillow are available on PyPi as wheels — the new standard packaging mechanism for Python. These prebuilt packages include all neccessary binary dependencies to allow Pillow to run and should be used if you want to install Pillow using PyPi

To use wheels, you need to have a version of pip>=1.4. If you are using an earlier version (pip --version) upgrade pip using the following:

pip install --upgrade pip 

Once pip is upgraded, pip install will use platform-specific wheel files by default if they are available. Use the following command to upgrade Pillow to the latest version available on PyPi:

pip install --upgrade pillow

Ubuntu 12.04 LTS or Raspian Wheezy 7.0

sudo apt-get install libtiff4-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk

Ubuntu 14.04

sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk

Ubuntu 18.04

sudo apt install libjpeg8-dev zlib1g-dev

Fedora 20

The Fedora 20 equivalent of libjpeg8-dev is libjpeg-devel.

sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel

Mac OS X (via Homebrew)

On Mac OS X with Homebrew this can be fixed using:

brew install libjpeg zlib

You may also need to force-link zlib using the following:

brew link zlib --force

Update April 2019: In Mojave the above will not work and you need to run the following as taken from this bug report on Pillow

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

Update July 2016: There is no longer a formula for zlib available in the main repository (Homebrew will prompt you to install lzlib which is a different library and will not solve this problem).

There is a formula available in the dupes repository. You can either tap this repository, and install as normal:

brew tap homebrew/dupes
brew install zlib

Or you can install zlib via xcode instead, as follows:

xcode-select --install

Thanks to phoenix, Panos Angelopoulou, nelsonvarela, benjaminz and Kal in the comments

After these are installed the pip installation of Pillow should work normally.

Maven uses batch files to do its business. With any batch script, you must call another script using the call command so it knows to return back to your script after the called script completes. Try prepending call to all commands.

Another thing you could try is using the start command which should work similarly.
