Here is how you can format your string without using DecimalFormat.

String.format("%02d", 9)

09

String.format("%03d", 19)

019

String.format("%04d", 119)

0119

There's also str_pad

<?php
$input = "Alien";
echo str_pad($input, 10);                      // produces "Alien     "
echo str_pad($input, 10, "-=", STR_PAD_LEFT);  // produces "-=-=-Alien"
echo str_pad($input, 10, "_", STR_PAD_BOTH);   // produces "__Alien___"
echo str_pad($input, 6 , "___");               // produces "Alien_"
?>

If you are using Visual Studio Community 2015 and trying to Install GLUT you should place the header file glut.h in C:\Program Files (x86)\Windows Kits\8.1\Include\um\gl

Adding an $(this).html(''); to clear visible data as well, and it works pretty fine

Use document.querySelector('input[type = radio]:checked').value; to get value of selected checkbox , you can use other attributes to get value like name = gender etc. please go through below snippet definitely it will helpful to you,

Solution

document.mainForm.onclick = function(){_x000D_
    var gender = document.querySelector('input[name = gender]:checked').value;_x000D_
    result.innerHTML = 'You Gender: '+gender;_x000D_
}

<form id="mainForm" name="mainForm">_x000D_
    <input type="radio" name="gender" value="Male" checked/>Male_x000D_
    <input type="radio" name="gender" value="Female" />Female_x000D_
    <input type="radio" name="gender" value="Others" />Others_x000D_
</form>_x000D_
<span id="result"></span>

Thank-You

By the time this question was posed there were some kinks with version ranges in maven, but these have been resolved in newer versions of maven. This article captures very well how version ranges work and best practices to better understand how maven understands versions: https://docs.oracle.com/middleware/1212/core/MAVEN/maven_version.htm#MAVEN8855

You want to use DATEADD, using a negative duration. e.g.

DATEADD(minute, -15, '2000-01-01 08:30:00') 

In Python using generators for very large directories, including blank extensions, and getting the number of times each extension shows up:

import json
import collections
import itertools
import os

root = '/home/andres'
files = itertools.chain.from_iterable((
    files for _,_,files in os.walk(root)
    ))
counter = collections.Counter(
    (os.path.splitext(file_)[1] for file_ in files)
)
print json.dumps(counter, indent=2)

The HTTP Content-Type for .ogg should be application/ogg (video/ogg for .ogv) and for .mp4 it should be video/mp4. You can check using the Web Sniffer.

Something like this works fine for me:

public partial class Form1 : Form
{
    Form mainFormHandler;
...
}

private void Form1_Load(object sender, EventArgs e){
    mainFormHandler = Application.OpenForms[0];
   //or instead use this one:
   //mainFormHandler = Application.OpenForms["Form1"];
}

Then you can change the size as below:

mainFormHandler.Width = 600;
mainFormHandler.Height= 400;

or

mainFormHandler.Size = new Size(600, 400);

Another useful point is that if you want to change the size of mainForm from another Form, you can simply use Property to set the size.

This is the simplest approach I follow. Consider I want to paste java code.

1. I paste the code here so that spaces, tabs and flower brackets are neatly formated http://www.tutorialspoint.com/online_java_formatter.htm

2. Then I paste the code got from step 1 here so that the colors, fonts are added to the code http://markup.su/highlighter/

3. Then paste the preview code got from step 2 to the MS word. Finally it will look like this

In addition to Varun Achar's answer, this is the Java 8 variant I came up with, that uses java.time.LocalDate and ZonedDateTime instead of the old java.util.Date classes.

public class LocalDateDeserializer extends JsonDeserializer<LocalDate> {

    @Override
    public LocalDate deserialize(JsonParser jsonparser, DeserializationContext deserializationcontext) throws IOException {

        String string = jsonparser.getText();

        if(string.length() > 20) {
            ZonedDateTime zonedDateTime = ZonedDateTime.parse(string);
            return zonedDateTime.toLocalDate();
        }

        return LocalDate.parse(string);
    }
  }

EDIT: Starting from IPython 3 (now Jupyter project), the notebook has a text editor that can be used as a more convenient alternative to load/edit/save text files.

A text file can be loaded in a notebook cell with the magic command %load.

If you execute a cell containing:

%load filename.py

the content of filename.py will be loaded in the next cell. You can edit and execute it as usual.

To save the cell content back into a file add the cell-magic %%writefile filename.py at the beginning of the cell and run it. Beware that if a file with the same name already exists it will be silently overwritten.

To see the help for any magic command add a ?: like %load? or %%writefile?.

For general help on magic functions type "%magic" For a list of the available magic functions, use %lsmagic. For a description of any of them, type %magic_name?, e.g. '%cd?'.

See also: Magic functions from the official IPython docs.

Change your code to

document.write("<td width='74'><button id='button' type='button' onclick='myfunction(\""+ name + "\")'>click</button></td>")

You'll need to get those bytes into a MemoryStream:

Bitmap bmp;
using (var ms = new MemoryStream(imageData))
{
    bmp = new Bitmap(ms);
}

That uses the Bitmap(Stream stream) constructor overload.

UPDATE: keep in mind that according to the documentation, and the source code I've been reading through, an ArgumentException will be thrown on these conditions:

stream does not contain image data or is null.
-or-
stream contains a PNG image file with a single dimension greater than 65,535 pixels.

.reduce((o,v,i)=>(o[i]=v,o), {})

[docs]

or more verbose

var trAr2Obj = function (arr) {return arr.reduce((o,v,i)=>(o[i]=v,o), {});}

or

var transposeAr2Obj = arr=>arr.reduce((o,v,i)=>(o[i]=v,o), {})

shortest one with vanilla JS

JSON.stringify([["a", "X"], ["b", "Y"]].reduce((o,v,i)=>{return o[i]=v,o}, {}))
=> "{"0":["a","X"],"1":["b","Y"]}"

some more complex example

[["a", "X"], ["b", "Y"]].reduce((o,v,i)=>{return o[v[0]]=v.slice(1)[0],o}, {})
=> Object {a: "X", b: "Y"}

even shorter (by using function(e) {console.log(e); return e;} === (e)=>(console.log(e),e))

? nodejs
> [[1, 2, 3], [3,4,5]].reduce((o,v,i)=>(o[v[0]]=v.slice(1),o), {})
{ '1': [ 2, 3 ], '3': [ 4, 5 ] }

In my case I created a database and gave the collation 'utf8_general_ci' but the required collation was 'latin1'. After changing my collation type to latin1_bin the error was gone.

Bitmap scaledBitmap = scaleDown(realImage, MAX_IMAGE_SIZE, true);

You can also put resources which you do not want to translate to file called donottranslate.xml.

You can not serialize a Python 3 'string' to bytes without explict conversion to some encoding.

outfile.write(plaintext.encode('utf-8'))

is possibly what you want. Also this works for both python 2.x and 3.x.

new File("path_to_file").toURI().toURL();

#'re.IGNORECASE' for case insensitive results short form re.I
#'re.match' returns the first match located from the start of the string. 
#'re.search' returns location of the where the match is found 
#'re.compile' creates a regex object that can be used for multiple matches

 >>> s = r'TeSt'   
 >>> print (re.match(s, r'test123', re.I))
 <_sre.SRE_Match object; span=(0, 4), match='test'>
 # OR
 >>> pattern = re.compile(s, re.I)
 >>> print(pattern.match(r'test123'))
 <_sre.SRE_Match object; span=(0, 4), match='test'>

Use the break keyword.

Extending off of Rapti's answer, this should work just as well, but it adds more margin to the right side of the body and hides it with negative html margin, instead of adding extra padding that could potentially affect the page's layout. This way, nothing is changed on the actual page (in most cases), and the code is still functional.

html {
    margin-right: calc(100% - 100vw);
}
body {
    margin-right: calc(100vw - 100%);
}

I guess you want to use to edit the json text. Then you can use ivarni's way:

{{data | json}}

 editable

<pre contenteditable="true">{{data | json}}</pre>

Hope this can help you.

This is what i normally work by when designing the interface of a non-template function:

1. Pass by value if the function does not want to modify the parameter and the value is cheap to copy (int, double, float, char, bool, etc... Notice that std::string, std::vector, and the rest of the containers in the standard library are NOT)

2. Pass by const pointer if the value is expensive to copy and the function does not want to modify the value pointed to and NULL is a value that the function handles.

3. Pass by non-const pointer if the value is expensive to copy and the function wants to modify the value pointed to and NULL is a value that the function handles.

4. Pass by const reference when the value is expensive to copy and the function does not want to modify the value referred to and NULL would not be a valid value if a pointer was used instead.

5. Pass by non-const reference when the value is expensive to copy and the function wants to modify the value referred to and NULL would not be a valid value if a pointer was used instead.

In .Net 4.0, you can also call String.IsNullOrWhitespace.

You're not running a module -- you're running subroutines/functions that happen to be stored in modules.

If you put the code in a standalone module and don't specify scope in the definitions of your subroutines/functions, they will be public by default, and callable from anywhere within your application. This means that you can call them with RunCode in a macro, from the class modules of forms/reports, from standalone class modules, or for the functions, from SQL (with some caveats).

Given that you were trying to implement in VBA something that you felt was too complicated for SQL, SQL is the likely context in which you want to execute the code. So, you should just be able to call your function within the SQL statement:

  SELECT MyTable.PersonID, MyTable.FirstName, MyTable.LastName, FormatAddress([Address], [City], [State], [Zip], [Country]) As Address
  FROM MyTable;

That SQL calls a public function called FormatAddress() that takes as arguments the components of an address and formats them appropriately. It's a trivial example as you likely would not need a VBA function for that purpose, but the point is that this is how you call functions from within a SQL statement.

Subroutines (i.e., code that returns no value) are not callable from within SQL statements.

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

I would suggest Travis for Open source project. It's just simple to configure and use.

Simple steps to setup:

1. Should have GITHUB account and register in Travis CI website using your GITHUB account.
2. Add .travis.yml file in root of your project. Add Travis as service in your repository settings page.

Now every time you commit into your repository Travis will build your project. You can follow simple steps to get started with Travis CI.

tomcat.sh helps you know this easily.

tomcat.sh usage doc says:

no argument: display the process-id of the tomcat, if it's running, otherwise do nothing

So, run command on your command prompt and check for pid:

$ tomcat.sh

I have just encountered this problem and my solution is to subclass json.JSONEncoder:

from datetime import datetime
import json

class DateTimeEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, datetime):
            return o.isoformat()

        return json.JSONEncoder.default(self, o)

In your call do something like: json.dumps(yourobj, cls=DateTimeEncoder) The .isoformat() I got from one of the answers above.

md-icons aren't in the bower release of angular-material yet. I've been using Polymer's icons, they'll probably be the same anyway.

Although ObjectMapper is thread safe, I would strongly discourage from declaring it as a static variable, especially in multithreaded application. Not even because it is a bad practice, but because you are running a heavy risk of deadlocking. I am telling it from my own experience. I created an application with 4 identical threads that were getting and processing JSON data from web services. My application was frequently stalling on the following command, according to the thread dump:

Map aPage = mapper.readValue(reader, Map.class);

Beside that, performance was not good. When I replaced static variable with the instance based variable, stalling disappeared and performance quadrupled. I.e. 2.4 millions JSON documents were processed in 40min.56sec., instead of 2.5 hours previously.

You need to add extra nginx directive (for ngx_http_proxy_module) in nginx.conf, e.g.:

proxy_read_timeout 300;

Basically the nginx proxy_read_timeout directive changes the proxy timeout, the FcgidIOTimeout is for scripts that are quiet too long, and FcgidBusyTimeout is for scripts that take too long to execute.

Also if you're using FastCGI application, increase these options as well:

FcgidBusyTimeout 300
FcgidIOTimeout 250

Then reload nginx and PHP5-FPM.

Plesk

In Plesk, you can add it in Web Server Settings under Additional nginx directives.

For FastCGI check in Web Server Settings under Additional directives for HTTP.

^{See: How to fix FastCGI timeout issues in Plesk?}

if you want generate a random float with N digits to the right of point, you can make this :

round(random.uniform(1,2), N)

the second argument is the number of decimals.

Naive approach

def transpose_finite_iterable(iterable):
    return zip(*iterable)  # `itertools.izip` for Python 2 users

works fine for finite iterable (e.g. sequences like list/tuple/str) of (potentially infinite) iterables which can be illustrated like

| |a_00| |a_10| ... |a_n0| |
| |a_01| |a_11| ... |a_n1| |
| |... | |... | ... |... | |
| |a_0i| |a_1i| ... |a_ni| |
| |... | |... | ... |... | |

where

• n in N,
• a_ij corresponds to j-th element of i-th iterable,

and after applying transpose_finite_iterable we get

| |a_00| |a_01| ... |a_0i| ... |
| |a_10| |a_11| ... |a_1i| ... |
| |... | |... | ... |... | ... |
| |a_n0| |a_n1| ... |a_ni| ... |

Python example of such case where a_ij == j, n == 2

>>> from itertools import count
>>> iterable = [count(), count()]
>>> result = transpose_finite_iterable(iterable)
>>> next(result)
(0, 0)
>>> next(result)
(1, 1)

But we can't use transpose_finite_iterable again to return to structure of original iterable because result is an infinite iterable of finite iterables (tuples in our case):

>>> transpose_finite_iterable(result)
... hangs ...
Traceback (most recent call last):
  File "...", line 1, in ...
  File "...", line 2, in transpose_finite_iterable
MemoryError

So how can we deal with this case?

... and here comes the deque

After we take a look at docs of itertools.tee function, there is Python recipe that with some modification can help in our case

def transpose_finite_iterables(iterable):
    iterator = iter(iterable)
    try:
        first_elements = next(iterator)
    except StopIteration:
        return ()
    queues = [deque([element])
              for element in first_elements]

    def coordinate(queue):
        while True:
            if not queue:
                try:
                    elements = next(iterator)
                except StopIteration:
                    return
                for sub_queue, element in zip(queues, elements):
                    sub_queue.append(element)
            yield queue.popleft()

    return tuple(map(coordinate, queues))

let's check

>>> from itertools import count
>>> iterable = [count(), count()]
>>> result = transpose_finite_iterables(transpose_finite_iterable(iterable))
>>> result
(<generator object transpose_finite_iterables.<locals>.coordinate at ...>, <generator object transpose_finite_iterables.<locals>.coordinate at ...>)
>>> next(result[0])
0
>>> next(result[0])
1

Synthesis

Now we can define general function for working with iterables of iterables ones of which are finite and another ones are potentially infinite using functools.singledispatch decorator like

from collections import (abc,
                         deque)
from functools import singledispatch


@singledispatch
def transpose(object_):
    """
    Transposes given object.
    """
    raise TypeError('Unsupported object type: {type}.'
                    .format(type=type))


@transpose.register(abc.Iterable)
def transpose_finite_iterables(object_):
    """
    Transposes given iterable of finite iterables.
    """
    iterator = iter(object_)
    try:
        first_elements = next(iterator)
    except StopIteration:
        return ()
    queues = [deque([element])
              for element in first_elements]

    def coordinate(queue):
        while True:
            if not queue:
                try:
                    elements = next(iterator)
                except StopIteration:
                    return
                for sub_queue, element in zip(queues, elements):
                    sub_queue.append(element)
            yield queue.popleft()

    return tuple(map(coordinate, queues))


def transpose_finite_iterable(object_):
    """
    Transposes given finite iterable of iterables.
    """
    yield from zip(*object_)

try:
    transpose.register(abc.Collection, transpose_finite_iterable)
except AttributeError:
    # Python3.5-
    transpose.register(abc.Mapping, transpose_finite_iterable)
    transpose.register(abc.Sequence, transpose_finite_iterable)
    transpose.register(abc.Set, transpose_finite_iterable)

which can be considered as its own inverse (mathematicians call this kind of functions "involutions") in class of binary operators over finite non-empty iterables.

As a bonus of singledispatching we can handle numpy arrays like

import numpy as np
...
transpose.register(np.ndarray, np.transpose)

and then use it like

>>> array = np.arange(4).reshape((2,2))
>>> array
array([[0, 1],
       [2, 3]])
>>> transpose(array)
array([[0, 2],
       [1, 3]])

Note

Since transpose returns iterators and if someone wants to have a tuple of lists like in OP -- this can be made additionally with map built-in function like

>>> original = [('a', 1), ('b', 2), ('c', 3), ('d', 4)]
>>> tuple(map(list, transpose(original)))
(['a', 'b', 'c', 'd'], [1, 2, 3, 4])

Advertisement

I've added generalized solution to lz package from 0.5.0 version which can be used like

>>> from lz.transposition import transpose
>>> list(map(tuple, transpose(zip(range(10), range(10, 20)))))
[(0, 1, 2, 3, 4, 5, 6, 7, 8, 9), (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)]

P.S.

There is no solution (at least obvious) for handling potentially infinite iterable of potentially infinite iterables, but this case is less common though.

A simple find and replace for a single character would go something like:

s.replace(s.find("x"), 1, "y")

To do this for the whole string, the easy thing to do would be to loop until your s.find starts returning npos. I suppose you could also catch range_error to exit the loop, but that's kinda ugly.

Use this one, it is trusted solution and works well for all browsers:

protected void clearInput(WebElement webElement) {
    // isIE() - just checks is it IE or not - use your own implementation
    if (isIE() && "file".equals(webElement.getAttribute("type"))) {
        // workaround
        // if IE and input's type is file - do not try to clear it.
        // If you send:
        // - empty string - it will find file by empty path
        // - backspace char - it will process like a non-visible char
        // In both cases it will throw a bug.
        // 
        // Just replace it with new value when it is need to.
    } else {
        // if you have no StringUtils in project, check value still empty yet
        while (!StringUtils.isEmpty(webElement.getAttribute("value"))) {
            // "\u0008" - is backspace char
            webElement.sendKeys("\u0008");
        }
    }
}

If input has type="file" - do not clear it for IE. It will try to find file by empty path and will throw a bug.

In Android Studio 3.4.2

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

Use ISNULL:

ISNULL(MY_FIELD1, 'NULL') = ISNULL(@IN_MY_FIELD1, 'NULL')

You can change 'NULL' to something like 'All Values' if it makes more sense to do so.

It should be noted that with two arguments, ISNULL works the same as COALESCE, which you could use if you have a few values to test (i.e.-COALESCE(@IN_MY_FIELD1, @OtherVal, 'NULL')). COALESCE also returns after the first non-null, which means it's (marginally) faster if you expect MY_FIELD1 to be blank. However, I find ISNULL much more readable, so that's why I used it, here.

You can combine both for better :

private class MyPagerAdapter extends FragmentStatePagerAdapter {

    //... your existing code

    @Override
    public int getItemPosition(Object object){

      if(Any_Reason_You_WantTo_Update_Positions) //this includes deleting or adding pages
 return PagerAdapter.POSITION_NONE;
    }
else
return PagerAdapter.POSITION_UNCHANGED; //this ensures high performance in other operations such as editing list items.

}

This solution fixed my problem while replacing br tag to '\n' .

alert(content.replace(/<br\/\>/g,'\n'));

The query either returned no rows or is erroneus, thus FALSE is returned. Change it to

if (!$dbc || mysqli_num_rows($dbc) == 0)

mysqli_num_rows:

Return Values

Returns TRUE on success or FALSE on failure. For SELECT, SHOW, DESCRIBE or EXPLAIN mysqli_query() will return a result object.

• Unit test: an automatic test to test the internal workings of a class. It should be a stand-alone test which is not related to other resources.
• Integration test: an automatic test that is done on an environment, so similar to unit tests but with external resources (db, disk access)
• Regression test: after implementing new features or bug fixes, you re-test scenarios which worked in the past. Here you cover the possibility in which your new features break existing features.
• Smoke testing: first tests on which testers can conclude if they will continue testing.

To configure IIS to run 32-bit applications you must follow these steps:

Open IIS
Go to current server – > Application Pools
Select the application pool your 32-bit application will run under
Click Advanced setting or Application Pool Default
Set Enable 32-bit Applications to True

If this option is not available to you, follow these next steps:

Go to %windir%\system32\inetsrv\
Execute the appcmd.exe tool:

It won't throw exception, you'll get an empty list.

It's worth noting that event.target can be useful, for example, for using a single listener to trigger different actions. Let's say you have the typical "menu" sprite with 10 buttons inside, so instead of doing:

menu.button1.addEventListener(MouseEvent.CLICK, doAction1);
menu.button2.addEventListener(MouseEvent.CLICK, doAction2);
etc...

You can simply do:

menu.addEventListener(MouseEvent.CLICK, doAction);

And trigger a different action within doAction(event) depending on the event.target (using it's name property, etc...)

You can use .toggle() function instead of .click()....

Microsoft do not support C99 and haven't announced any plans to. I believe they intend to track C++ standards but consider C as effectively obsolete except as a subset of C++.

New projects in Visual Studio 2003 and later have the "Compile as C++ Code (/TP)" option set by default, so any .c files will be compiled as C++.

In typescript, the declaration is something like this:

const regex : RegExp = /.+\*.+/;

using RegExp constructor:

const regex = new RegExp('.+\\*.+');

Use SpannableBuilder class instead of HTML formatting where it possible because it more faster then HTML format parsing. See my own benchmark "SpannableBuilder vs HTML" on Github Thanks!

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

Normally updating certifi and/or the certifi cacert.pem file would work. I also had to update my version of python. Vs. 2.7.5 wasn't working because of how it handles SNI requests.

Once you have an up to date pem file you can make your http request using:

requests.get(url, verify='/path/to/cacert.pem')

You can change build versiyon.For example i tried QT 5.6.1 but it didn't work.Than i tried QT 5.7.0 .So it worked , Good Luck! :)

Most of the answers for this question can not helped me in 2020.

This notification from download site of Oracle may be the reason:

Important Oracle JDK License Update

The Oracle JDK License has changed for releases starting April 16, 2019.

I try to google a little bit and those tutorials below helped me a lot.

1. Remove completely the previous version of JVM installed on your PC.

   sudo update-alternatives --remove-all java
   sudo update-alternatives --remove-all javac
   sudo update-alternatives --remove-all javaws
   
   # /usr/lib/jvm/jdk1.7.0 is the path you installed the previous version of JVM on your PC
   sudo rm -rf /usr/lib/jvm/jdk1.7.0 
   

   Check to see whether java is uninstalled or not

   java -version
   

2. Install Java 8 JDK.

   • Download Java 8 from Oracle's website. The version being used is 1.8.0_251. Pay attention to this value, you may need it to edit commands in this answer when Java 8 is upgraded to another version.
   • Extract the compressed file to the place where you want to install.

   cd /usr/lib/jvm
   sudo tar xzf ~/Downloads/jdk-8u251-linux-x64.tar.gz
   

   • Edit environment file

   sudo gedit /etc/environment
   

   • Edit the PATH's value by appending the string below to the current value

   :/usr/lib/jvm/jdk1.8.0_251/bin:/usr/lib/jvm/jdk1.8.0_251/jre/bin
   

   • Append those strings to the environment file

   J2SDKDIR="/usr/lib/jvm/jdk1.8.0_251"
   J2REDIR="/usr/lib/jvm/jdk1.8.0_251/jre"
   JAVA_HOME="/usr/lib/jvm/jdk1.8.0_251"
   

   • Complete the installation by running commands below

   sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_251/bin/java" 0
   sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0_251/bin/javac" 0
   sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_251/bin/java
   sudo update-alternatives --set javac /usr/lib/jvm/jdk1.8.0_251/bin/javac
   
   update-alternatives --list java
   update-alternatives --list javac
   

The question is already answered but I think I've found the solution that is simpler and more relevant to the question title, here it is:

var cli = new WebClient();
cli.Headers[HttpRequestHeader.ContentType] = "application/json";
string response = cli.UploadString("http://some/address", "{some:\"json data\"}");

PS: In the most of .net implementations, but not in all WebClient is IDisposable, so of cource it is better to do 'using' or 'Dispose' on it. However in this particular case it is not really necessary.

For a time difference, note that the calendar starts at 01.01.1970, 01:00, not at 00:00. If you're using java.util.Date and java.text.SimpleDateFormat, you will have to compensate for 1 hour:

long start = System.currentTimeMillis();
long end = start + (1*3600 + 23*60 + 45) * 1000 + 678; // 1 h 23 min 45.678 s
Date timeDiff = new Date(end - start - 3600000); // compensate for 1h in millis
SimpleDateFormat timeFormat = new SimpleDateFormat("H:mm:ss.SSS");
System.out.println("Duration: " + timeFormat.format(timeDiff));

This will print:

Duration: 1:23:45.678

Batch Files automatically pass the text after the program so long as their are variables to assign them to. They are passed in order they are sent; e.g. %1 will be the first string sent after the program is called, etc.

If you have Hello.bat and the contents are:

@echo off
echo.Hello, %1 thanks for running this batch file (%2)
pause

and you invoke the batch in command via

hello.bat APerson241 %date%

you should receive this message back:

Hello, APerson241 thanks for running this batch file (01/11/2013)

To use IN, you must have a set, use this syntax instead:

SELECT * FROM Table1 WHERE Table1.principal NOT IN (SELECT principal FROM table2)

jQuery now supports scrollTop as an animation variable.

$("#id").animate({"scrollTop": $("#id").scrollTop() + 100});

You no longer need to setTimeout/setInterval to scroll smoothly.

SELECT p.pid, p.cid, p.pname, c1.name1, c2.name2
FROM product p
LEFT JOIN customer1 c1 ON p.cid = c1.cid
LEFT JOIN customer2 c2 ON p.cid = c2.cid

Set nocount on

Exec sp_MSForEachTable 'Alter Table ? NoCheck Constraint All'

Exec sp_MSForEachTable
'
If ObjectProperty(Object_ID(''?''), ''TableHasForeignRef'')=1
Begin
-- Just to know what all table used delete syntax.
Print ''Delete from '' + ''?''
Delete From ?
End
Else
Begin
-- Just to know what all table used Truncate syntax.
Print ''Truncate Table '' + ''?''
Truncate Table ?
End
'

Exec sp_MSForEachTable 'Alter Table ? Check Constraint All'

This can also be done freely online: http://www.showmycode.com/

EDIT A quick Google search turned up this list, which probably has all the tools you could possibly want (look at the comments as well): http://bruce-lab.blogspot.co.il/2010/08/freeswfdecompilers.html

BufferedImage is a(n) Image, so the implicit cast that you're doing in the second line is able to be compiled directly. If you knew an Image was really a BufferedImage, you would have to cast it explicitly like so:

Image image = ImageIO.read(new File(file));
BufferedImage buffered = (BufferedImage) image;

Because BufferedImage extends Image, it can fit in an Image container. However, any Image can fit there, including ones that are not a BufferedImage, and as such you may get a ClassCastException at runtime if the type does not match, because a BufferedImage cannot hold any other type unless it extends BufferedImage.

Not exactly for this OP, but for those who encountered 404 and cannot set response content-type to "application/json" (any content-type). One possibility is a server actually responds 406 but explorer (e.g., chrome) prints it as 404.

If you do not customize message converter, spring would use AbstractMessageConverterMethodProcessor.java. It would run:

List<MediaType> requestedMediaTypes = getAcceptableMediaTypes(request);
List<MediaType> producibleMediaTypes = getProducibleMediaTypes(request, valueType, declaredType);

and if they do not have any overlapping (the same item), it would throw HttpMediaTypeNotAcceptableException and this finally causes 406. No matter if it is an ajax, or GET/POST, or form action, if the request uri ends with a .html or any suffix, the requestedMediaTypes would be "text/[that suffix]", and this conflicts with producibleMediaTypes, which is usually:

"application/json"  
"application/xml"   
"text/xml"          
"application/*+xml" 
"application/json"  
"application/*+json"
"application/json"  
"application/*+json"
"application/xml"   
"text/xml"          
"application/*+xml"
"application/xml"  
"text/xml"         
"application/*+xml"

I'm not sure if this is what you ask, but you can check gradle version of your project here in android studio:

(left pane must be in project view, not android for this path) app->gradle->wrapper->gradle-wrapper.properties

it has a line like this, indicating the gradle version:

distributionUrl=http\://services.gradle.org/distributions/gradle-1.8-all.zip

There is also a table at the end of this page that shows gradle and gradle plug-in versions supported by each android studio version. (you can check your android studio by checking help->about as you may already know)

If you need multiple columns to group by, follow this model. Here I am conducting a count by status and type:

  db.BusinessProcess.aggregate({
    "$group": {
        _id: {
            status: "$status",
            type: "$type"
        },
        count: {
            $sum: 1
        }
    }
   })

You can easily use the MODE argument:

MySQL :: MySQL 5.5 Reference Manual :: 12.7 Date and Time Functions

If the mode argument is omitted, the value of the default_week_format system variable is used:

MySQL :: MySQL 5.1 Reference Manual :: 5.1.4 Server System Variables

EDIT after a bit of researching:

It somehow seems that I have been fooled by the documentation present on Mozilla docs. The popstate event (and its callback function onpopstate) are not triggered whenever the pushState() or replaceState() are called in code. Therefore the original answer does not apply in all cases.

However there is a way to circumvent this by monkey-patching the functions according to @alpha123:

var pushState = history.pushState;
history.pushState = function () {
    pushState.apply(history, arguments);
    fireEvents('pushState', arguments);  // Some event-handling function
};

Original answer

Given that the title of this question is "How to detect URL change" the answer, when you want to know when the full path changes (and not just the hash anchor), is that you can listen for the popstate event:

window.onpopstate = function(event) {
  console.log("location: " + document.location + ", state: " + JSON.stringify(event.state));
};

Reference for popstate in Mozilla Docs

Currently (Jan 2017) there is support for popstate from 92% of browsers worldwide.

Use substring function
Check this out http://jsfiddle.net/kuc5as83/

var string = "1234567890"
var substr=string.substr(-8);
document.write(substr);

Output >> 34567890

substr(-8) will keep last 8 chars

var substr=string.substr(8);
document.write(substr);

Output >> 90

substr(8) will keep last 2 chars

var substr=string.substr(0, 8);
document.write(substr);

Output >> 12345678

substr(0, 8) will keep first 8 chars

Check this out string.substr(start,length)

def dec_to_bin(x):
    return int(bin(x)[2:])

It's that easy.

In case you're using apache's http-client 4:

SSLConnectionSocketFactory sslConnectionSocketFactory = 
    new SSLConnectionSocketFactory(sslContext,
             new String[] { "TLSv1.2" }, null, new HostnameVerifier() {
                    public boolean verify(String arg0, SSLSession arg1) {
                            return true;
            }
      });

ALTER TABLE `table_name` ADD PRIMARY KEY( `column_name`);

Excluding unwanted Manifest entries fixed the MainClass file not found error in a Gradle build jar file.

jar{
    exclude 'META-INF/*.SF', 'META-INF/*.DSA', 'META-INF/*.RSA', 'META-INF/*.MF'
    from {
      -----
    }
}

This may sound like the long way around, but you may want to look at using Excel to generate INSERT SQL code that you can past into Query Analyzer to create your table.

Works well if you cant use the wizards because the excel file isn't on the server

You can also turn on WCF logging for more information about the original error. This helped me solve this problem.

Add the following to your web.config, it saves the log to C:\log\Traces.svclog

<system.diagnostics>
    <sources>
        <source name="System.ServiceModel"
                  switchValue="Information, ActivityTracing"
                  propagateActivity="true">
            <listeners>
                <add name="traceListener"
                     type="System.Diagnostics.XmlWriterTraceListener"
                     initializeData= "c:\log\Traces.svclog" />
            </listeners>
        </source>
    </sources>
</system.diagnostics>

Here is a working solution:

#include <stdio.h>
#include <string.h>

int main(int argc, char** argv) 
{
      char str1[16];
      char str2[16];
      strcpy(str1, "sssss");
      strcpy(str2, "kkkk");
      strcat(str1, str2);
      printf("%s", str1);
      return 0;
}

Output:

ssssskkkk

You have to allocate memory for your strings. In the above code, I declare str1 and str2 as character arrays containing 16 characters. I used strcpy to copy characters of string literals into them, and strcat to append the characters of str2 to the end of str1. Here is how these character arrays look like during the execution of the program:

After declaration (both are empty): 
str1: [][][][][][][][][][][][][][][][][][][][] 
str2: [][][][][][][][][][][][][][][][][][][][]

After calling strcpy (\0 is the string terminator zero byte): 
str1: [s][s][s][s][s][\0][][][][][][][][][][][][][][] 
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

After calling strcat: 
str1: [s][s][s][s][s][k][k][k][k][\0][][][][][][][][][][] 
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

You can specify default options using the .gemrc configuration file.

The problem I have with solution

import sys

for line in sys.stdin:
    print(line)

is that if you don't pass any data to stdin, it will block forever. That's why I love this answer: check if there is some data on stdin first, and then read it. This is what I ended up doing:

import sys
import select

# select(files to read from, files to write to, magic, timeout)
# timeout=0.0 is essential b/c we want to know the asnwer right away
if select.select([sys.stdin], [], [], 0.0)[0]:
    help_file_fragment = sys.stdin.read()
else:
    print("No data passed to stdin", file=sys.stderr)
    sys.exit(2)

To modify a value every time a block of code runs without having to break execution flow:

The "Logpoints" feature in the debugger is designed to let you log arbitrary values to the console without breaking. It evaluates code inside the flow of execution, which means you can actually use it to change values on the fly without stopping.

Right-click a line number and choose "Logpoint," then enter the assignment expression. It looks something like this:

I find it super useful for setting values to a state not otherwise easy to reproduce, without having to rebuild my project with debug lines in it. REMEMBER to delete the breakpoint when you're done!

The easiest way is to use python-memcached-stats package, https://github.com/abstatic/python-memcached-stats

The keys() method should get you going.

Example -

from memcached_stats import MemcachedStats
mem = MemcachedStats()

mem.keys()
['key-1',
 'key-2',
 'key-3',
 ... ]

Since PHP 5.5, you can use array_column:

$ids = array_column($users, 'id');

This is the preferred option on any modern project. However, if you must support PHP<5.5, the following alternatives exist:

Since PHP 5.3, you can use array_map with an anonymous function, like this:

$ids = array_map(function ($ar) {return $ar['id'];}, $users);

Before ^{_{(Technically PHP 4.0.6+)}}, you must create an anonymous function with create_function instead:

$ids = array_map(create_function('$ar', 'return $ar["id"];'), $users);

To get the number of votes for a specific item, you would use:

vote_count = Item.objects.filter(votes__contest=contestA).count()

If you wanted a break down of the distribution of votes in a particular contest, I would do something like the following:

contest = Contest.objects.get(pk=contest_id)
votes   = contest.votes_set.select_related()

vote_counts = {}

for vote in votes:
  if not vote_counts.has_key(vote.item.id):
    vote_counts[vote.item.id] = {
      'item': vote.item,
      'count': 0
    }

  vote_counts[vote.item.id]['count'] += 1

This will create dictionary that maps items to number of votes. Not the only way to do this, but it's pretty light on database hits, so will run pretty quickly.

At least for me, the signal(SIGSEGV ...) approach mentioned in another answer did not work on Win32 with Visual C++ 2015. What did work for me was to use _set_se_translator() found in eh.h. It works like this:

Step 1) Make sure you enable Yes with SEH Exceptions (/EHa) in Project Properties / C++ / Code Generation / Enable C++ Exceptions, as mentioned in the answer by Volodymyr Frytskyy.

Step 2) Call _set_se_translator(), passing in a function pointer (or lambda) for the new exception translator. It is called a translator because it basically just takes the low-level exception and re-throws it as something easier to catch, such as std::exception:

#include <string>
#include <eh.h>

// Be sure to enable "Yes with SEH Exceptions (/EHa)" in C++ / Code Generation;
_set_se_translator([](unsigned int u, EXCEPTION_POINTERS *pExp) {
    std::string error = "SE Exception: ";
    switch (u) {
    case 0xC0000005:
        error += "Access Violation";
        break;
    default:
        char result[11];
        sprintf_s(result, 11, "0x%08X", u);
        error += result;
    };
    throw std::exception(error.c_str());
});

Step 3) Catch the exception like you normally would:

try{
    MakeAnException();
}
catch(std::exception ex){
    HandleIt();
};

The answer that @Matthew Crumley provides is making use of the immediately invoked function expressions, to close the older 'a' function into the execution context of the returned function. I think this was the best answer, but personally, I would prefer passing the function 'a' as an argument to IIFE. I think it is more understandable.

   var a = (function(original_a) {
        if (condition) {
            return function() {
                new_code();
                original_a();
            }
        } else {
            return function() {
                original_a();
                other_new_code();
            }
        }
    })(a);

Since the questions about best practice, I would add, that very often good idea to use hybrid approach for creating fragment when working with some REST web services

We can't pass complex objects, for example some User model, for case of displaying user fragment

But what we can do, is to check in onCreate that user!=null and if not - then bring him from data layer, otherwise - use existing.

This way we gain both ability to recreate by userId in case of fragment recreation by Android and snappiness for user actions, as well as ability to create fragments by holding to object itself or only it's id

Something likes this:

public class UserFragment extends Fragment {
    public final static String USER_ID="user_id";
    private User user;
    private long userId;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        userId = getArguments().getLong(USER_ID);
        if(user==null){
            //
            // Recreating here user from user id(i.e requesting from your data model,

By using pandas we can read excel easily.

import pandas as pd 
from pandas import ExcelWriter
from pandas import ExcelFile 

DataF=pd.read_excel("Test.xlsx",sheet_name='Sheet1')

print("Column headings:")
print(DataF.columns)

Test at :https://repl.it Reference: https://pythonspot.com/read-excel-with-pandas/

I had the same issue. I resolved it doing the following:

1. Add the this line to the dispatcher-servlet file:

   <tx:annotation-driven/>
   

   Check above <beans> section in the same file. These two lines must be present:

   xmlns:tx="http://www.springframework.org/schema/tx"
   xsi:schemaLocation= "http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"
   

2. Also make sure you added @Repository and @Transactional where you are using sessionFactory.

   @Repository
   @Transactional
   public class ItemDaoImpl implements ItemDao {
       @Autowired
       private SessionFactory sessionFactory;
   

If your goal is to have

str = "Hello\nWorld";

and output what it contains in string literal form, you can use JSON.stringify:

console.log(JSON.stringify(str)); // ""Hello\nWorld""

const str = "Hello\nWorld";_x000D_
const json = JSON.stringify(str);_x000D_
console.log(json); // ""Hello\nWorld""_x000D_
for (let i = 0; i < json.length; ++i) {_x000D_
    console.log(`${i}: ${json.charAt(i)}`);_x000D_
}

.as-console-wrapper {_x000D_
    max-height: 100% !important;_x000D_
}

console.log adds the outer quotes (at least in Chrome's implementation), but the content within them is a string literal (yes, that's somewhat confusing).

JSON.stringify takes what you give it (in this case, a string) and returns a string containing valid JSON for that value. So for the above, it returns an opening quote ("), the word Hello, a backslash (\), the letter n, the word World, and the closing quote ("). The linefeed in the string is escaped in the output as a \ and an n because that's how you encode a linefeed in JSON. Other escape sequences are similarly encoded.

Laravel 5

This is working for me (i use laravel 5.6).

$collection = MyModel::all()->groupBy('column');

If you want to convert the collection to plain php array, you can use toArray()

$array = MyModel::all()->groupBy('column')->toArray();

After replacing the character, you need to be asign to the variable.

var tt = "88,9827";
tt = tt.replace(/,/g, '.')
alert(tt)

In the alert box it will shows 88.9827

Yes, the first one is a static method also called class method, while the second one is an instance method.

Consider the following examples, to understand it in more detail.

In ES5

function Person(firstName, lastName) {
   this.firstName = firstName;
   this.lastName = lastName;
}

Person.isPerson = function(obj) {
   return obj.constructor === Person;
}

Person.prototype.sayHi = function() {
   return "Hi " + this.firstName;
}

In the above code, isPerson is a static method, while sayHi is an instance method of Person.

Below, is how to create an object from Person constructor.

var aminu = new Person("Aminu", "Abubakar");

Using the static method isPerson.

Person.isPerson(aminu); // will return true

Using the instance method sayHi.

aminu.sayHi(); // will return "Hi Aminu"

In ES6

class Person {
   constructor(firstName, lastName) {
      this.firstName = firstName;
      this.lastName = lastName;
   }

   static isPerson(obj) {
      return obj.constructor === Person;
   }

   sayHi() {
      return `Hi ${this.firstName}`;
   }
}

Look at how static keyword was used to declare the static method isPerson.

To create an object of Person class.

const aminu = new Person("Aminu", "Abubakar");

Using the static method isPerson.

Person.isPerson(aminu); // will return true

Using the instance method sayHi.

aminu.sayHi(); // will return "Hi Aminu"

NOTE: Both examples are essentially the same, JavaScript remains a classless language. The class introduced in ES6 is primarily a syntactical sugar over the existing prototype-based inheritance model.

I solved is by using android:background instead of app:srcCompact.

This is caused by xmlns:app="http://schemas.android.com/apk/res-auto". As people have suggested above, you could use /lib-auto or /lib/your-package but I got suspicious namespace error when I tried using /lib-auto and unexpected namespace prefix error with /lib/my-package .

If you have not pushed the changes already:

git rm -r --cached .
git add .
git commit -m 'clear git cache'
git push

Keys helps React identify which items have changed/added/removed and should be given to the elements inside the array to give the elements a stable identity.

With that in mind, there are basically three different strategies as described bellow:

1. Static Elements (when you don't need to keep html state (focus, cursor position, etc)
2. Editable and sortable elements
3. Editable but not sortable elements

As React Documentation explains, we need to give stable identity to the elements and because of that, carefully choose the strategy that best suits your needs:

STATIC ELEMENTS

As we can see also in React Documentation, is not recommended the use of index for keys "if the order of items may change. This can negatively impact performance and may cause issues with component state".

In case of static elements like tables, lists, etc, I recommend using a tool called shortid.

1) Install the package using NPM/YARN:

npm install shortid --save

2) Import in the class file you want to use it:

import shortid from 'shortid';

2) The command to generate a new id is shortid.generate().

3) Example:

  renderDropdownItems = (): React.ReactNode => {
    const { data, isDisabled } = this.props;
    const { selectedValue } = this.state;
    const dropdownItems: Array<React.ReactNode> = [];

    if (data) {
      data.forEach(item => {
        dropdownItems.push(
          <option value={item.value} key={shortid.generate()}>
            {item.text}
          </option>
        );
      });
    }

    return (
      <select
        value={selectedValue}
        onChange={this.onSelectedItemChanged}
        disabled={isDisabled}
      >
        {dropdownItems}
      </select>
    );
  };

IMPORTANT: As React Virtual DOM relies on the key, with shortid every time the element is re-rendered a new key will be created and the element will loose it's html state like focus or cursor position. Consider this when deciding how the key will be generated as the strategy above can be useful only when you are building elements that won't have their values changed like lists or read only fields.

EDITABLE (sortable) FIELDS

If the element is sortable and you have a unique ID of the item, combine it with some extra string (in case you need to have the same information twice in a page). This is the most recommended scenario.

Example:

  renderDropdownItems = (): React.ReactNode => {
    const elementKey:string = 'ddownitem_'; 
    const { data, isDisabled } = this.props;
    const { selectedValue } = this.state;
    const dropdownItems: Array<React.ReactNode> = [];

    if (data) {
      data.forEach(item => {
        dropdownItems.push(
          <option value={item.value} key={${elementKey}${item.id}}>
            {item.text}
          </option>
        );
      });
    }

    return (
      <select
        value={selectedValue}
        onChange={this.onSelectedItemChanged}
        disabled={isDisabled}
      >
        {dropdownItems}
      </select>
    );
  };

EDITABLE (non sortable) FIELDS (e.g. INPUT ELEMENTS)

As a last resort, for editable (but non sortable) fields like input, you can use some the index with some starting text as element key cannot be duplicated.

Example:

  renderDropdownItems = (): React.ReactNode => {
    const elementKey:string = 'ddownitem_'; 
    const { data, isDisabled } = this.props;
    const { selectedValue } = this.state;
    const dropdownItems: Array<React.ReactNode> = [];

    if (data) {
      data.forEach((item:any index:number) => {
        dropdownItems.push(
          <option value={item.value} key={${elementKey}${index}}>
            {item.text}
          </option>
        );
      });
    }

    return (
      <select
        value={selectedValue}
        onChange={this.onSelectedItemChanged}
        disabled={isDisabled}
      >
        {dropdownItems}
      </select>
    );
  };

Hope this helps.

Ran in to this problem a while ago. Website couldn't access video file on local PC due to security settings (understandable really) ONLY way I could get around it was to run a webserver on the local PC (server2Go) and all references to the video file from the web were to the localhost/video.mp4

<div id="videoDiv">
     <video id="video" src="http://127.0.0.1:4001/videos/<?php $videoFileName?>" width="70%" controls>
    </div>
<!--End videoDiv-->

Not an ideal solution but worked for me.

• Tokens need to be stored somewhere (local/session storage or cookies)

• Tokens can expire like cookies, but you have more control

• Local/session storage won't work across domains, use a marker cookie

• Preflight requests will be sent on each CORS request

• When you need to stream something, use the token to get a signed request

• It's easier to deal with XSS than XSRF

• The token gets sent on every request, watch out its size

• If you store confidential info, encrypt the token

• JSON Web Tokens can be used in OAuth

• Tokens are not silver bullets, think about your authorization use cases carefully

Use boolean indexing as you would do in numpy.array

df = pd.DataFrame({'Data':np.random.normal(size=200)})
# example dataset of normally distributed data. 

df[np.abs(df.Data-df.Data.mean()) <= (3*df.Data.std())]
# keep only the ones that are within +3 to -3 standard deviations in the column 'Data'.

df[~(np.abs(df.Data-df.Data.mean()) > (3*df.Data.std()))]
# or if you prefer the other way around

For a series it is similar:

S = pd.Series(np.random.normal(size=200))
S[~((S-S.mean()).abs() > 3*S.std())]

df=pd.read_csv("filename.csv" , parse_dates=["<column name>"])

type(df.<column name>)

example: if you want to convert day which is initially a string to a Timestamp in Pandas

df=pd.read_csv("weather_data2.csv" , parse_dates=["day"])

type(df.day)

The output will be pandas.tslib.Timestamp

This will end the function, and you can even customize the "Error" message:

    if condition:
        # the player wants to play again:
        main()
    elif not condition:
        sys.exit("The player doesn't want to play again") #Right here

No.1: list(), [:], copy.copy() are all shallow copy. If an object is compound, they are all not suitable. You need to use copy.deepcopy().

No.2: b = a directly, a and b have the same reference, changing a is even as changing b.

If you have a res/raw folder, be sure to add a file with a valid filename, otherwise the entire folder won't show up in the R class. If there's an error with a filename, it will appear in red in the console.

This snippet of code is taken out of the AspNetIdentitySample project available on github

For me.

Edit .gitattributes file.

add

*.dll binary

Then everything goes well.

Like this:

>>>mystr = "abcdefghijkl"
>>>mystr[-4:]
'ijkl'

This slices the string's last 4 characters. The -4 starts the range from the string's end. A modified expression with [:-4] removes the same 4 characters from the end of the string:

>>>mystr[:-4]
'abcdefgh'

For more information on slicing see this Stack Overflow answer.

If you want to search deleted record (Soft Deleted Record), do't user Eloquent Model Query. Instead use Db::table query e.g Instead of using Below:

$stu = Student::where('rollNum', '=', $rollNum . '-' . $nursery)->first();

Use:

$stu = DB::table('students')->where('rollNum', '=', $newRollNo)->first();

A tuple is immutable and thus you get the error you posted.

>>> pixels = [1, 2, 3]
>>> pixels[0] = 5
>>> pixels = (1, 2, 3)
>>> pixels[0] = 5
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment

In your specific case, as correctly pointed out in other answers, you should write:

pixel = (pixel[0] + 20, pixel[1], pixel[2])

Where returns a new sequence of items matching the predicate.

Any returns a Boolean value; there's a version with a predicate (in which case it returns whether or not any items match) and a version without (in which case it returns whether the query-so-far contains any items).

I'm not sure about Exists - it's not a LINQ standard query operator. If there's a version for the Entity Framework, perhaps it checks for existence based on a key - a sort of specialized form of Any? (There's an Exists method in List<T> which is similar to Any(predicate) but that predates LINQ.)

You can use the is_a? method

>> 1.is_a? Integer
=> true
>> "[email protected]".is_a? Integer
=> false
>> nil.is_a? Integer
=> false

Use .map without return in simple way. Also start using let and const instead of var because let and const is more recommended

If you are using Qt, try rerunning qmake. If this error is in the widget's class, qmake might have failed to notice that the ui class vtable should be regenerated. This fixed the issue for me.

Set the tabindex of the canvas element to 1 or something like this

<canvas tabindex='1'></canvas>

It's an old trick to make any element focusable

From javascript, you should be able to get the filename in the onsubmit handler. So in your case, you should do something like:

<form onsubmit="if (document.getElementById('fileUpload').value.match(/xls$/) || document.getElementById('fileUpload').value.match(/xlsx$/)) { alert ('Bad file type') ; return false; } else { return true; }">...</form>

Action normally specifies the file/page that the form is submitted to (using the method described in the method paramater (post, get etc.))

An action of # indicates that the form stays on the same page, simply suffixing the url with a #. Similar use occurs in anchors. <a href=#">Link</a> for example, will stay on the same page.

Thus, the form is submitted to the same page, which then processes the data etc.

In my case I wanted to remove jsonobject with status as non zero value, so what I did is made a function "removeJsonObject" which takes old json and gives required json and called that function inside the constuctor.

public CommonAdapter(Context context, JSONObject json, String type) {
        this.context=context;
        this.json= removeJsonObject(json);
        this.type=type;
        Log.d("CA:", "type:"+type);

    }

public JSONObject removeJsonObject(JSONObject jo){
        JSONArray ja= null;
        JSONArray jsonArray= new JSONArray();
        JSONObject jsonObject1=new JSONObject();

        try {
            ja = jo.getJSONArray("data");

        } catch (JSONException e) {
            e.printStackTrace();
        }
        for(int i=0; i<ja.length(); i++){
            try {

                if(Integer.parseInt(ja.getJSONObject(i).getString("status"))==0)
                {
                    jsonArray.put(ja.getJSONObject(i));
                    Log.d("jsonarray:", jsonArray.toString());
                }


            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
        try {
            jsonObject1.put("data",jsonArray);
            Log.d("jsonobject1:", jsonObject1.toString());

            return jsonObject1;
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return json;
    }

Post::where('id',3)->update(['title'=>'Updated title']);

This is a solution for Swift 4

 in tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)

just add

tableView.deselectRow(at: indexPath, animated: true)

it works like a charm

example:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)
//some code
}

Does this work without alternation?

^((part)1(, \22)?)?(part2)?$

or why not this?

^((part)1(, (\22))?)?(\4)?$

The first works for all conditions the second for all but part2(using GNU sed 4.1.5)

YouTube supports a fairly easy to use iframe and url interface to embed videos, playlists and all user uploads to your channel: https://developers.google.com/youtube/player_parameters

For example this HTML will embed a player loaded with a playlist of all the videos uploaded to your channel. Replace YOURCHANNELNAME with the actual name of your channel:

<iframe src="http://www.youtube.com/embed/?listType=user_uploads&list=YOURCHANNELNAME" width="480" height="400"></iframe>

Forward declaring things in C++ is very useful because it dramatically speeds up compilation time. You can forward declare several things in C++ including: struct, class, function, etc...

But can you forward declare an enum in C++?

No you can't.

But why not allow it? If it were allowed you could define your enum type in your header file, and your enum values in your source file. Sounds like it should be allowed right?

Wrong.

In C++ there is no default type for enum like there is in C# (int). In C++ your enum type will be determined by the compiler to be any type that will fit the range of values you have for your enum.

What does that mean?

It means that your enum's underlying type cannot be fully determined until you have all of the values of the enum defined. Which mans you cannot separate the declaration and definition of your enum. And therefore you cannot forward declare an enum in C++.

The ISO C++ standard S7.2.5:

The underlying type of an enumeration is an integral type that can represent all the enumerator values defined in the enumeration. It is implementation-defined which integral type is used as the underlying type for an enumeration except that the underlying type shall not be larger than int unless the value of an enumerator cannot fit in an int or unsigned int. If the enumerator-list is empty, the underlying type is as if the enumeration had a single enumerator with value 0. The value of sizeof() applied to an enumeration type, an object of enumeration type, or an enumerator, is the value of sizeof() applied to the underlying type.

You can determine the size of an enumerated type in C++ by using the sizeof operator. The size of the enumerated type is the size of its underlying type. In this way you can guess which type your compiler is using for your enum.

What if you specify the type of your enum explicitly like this:

enum Color : char { Red=0, Green=1, Blue=2};
assert(sizeof Color == 1);

Can you then forward declare your enum?

No. But why not?

Specifying the type of an enum is not actually part of the current C++ standard. It is a VC++ extension. It will be part of C++0x though.

In my case, Re-enabling TLS 1.0 in the DB server resolved this issue.

you just need to divide the Date Time stamp by 1000 like:

var a = 1437203995000;
a = (a)/1000;

This worked for me Visual C++ Redistributable Packages

Retrieve timezone by name (i.e. "America/New York")

The reason this particular exception gets thrown is that the content of the element gets applied to the ListView's Items collection. So the XAML initialises the ListView with a single local:ImageView in its Items collection. But when using an ItemsControl you must use either the Items property or the ItemsSource property, you can't use both at the same time. Hence when the ItemsSource attribute gets processed an exception is thrown.

You can find out which property the content of an element will get applied to by looking for the ContentPropertyAttribute on the class. In this case it's defined higher in the class hierarchy, on the ItemsControl:

[ContentPropertyAttribute("Items")]

The intention here was that the ListView's View be set to a local:ImageView so the fix is to explicitly indicate the property to be set.

Fix the XAML and the exception goes away:

<ListView Name="ListViewImages"
          SelectionMode="Single"
          ItemsSource="{Binding}">
    <ListView.View>
        <local:ImageView />
    </ListView.View>
</ListView>

It was missing that <ListView.View> tag.

Here's more modern approach:

.parent {display: flow-root;} 

No more clearfixes.

p.s. Using overflow: hidden; hides the box-shadow so...

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

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

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

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

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

They are both the same functionally but the .min one has all unnecessary characters removed in order to make the file size smaller.

Just to point out as well, you are better using the minified version (.min) for your live environment as Google are now checking on page loading times. Having all your JS file minified means they will load faster and will score you more brownie points.

You can get an addon for Mozilla called Page Speed that will look through your site and show you all the .JS files and provide minified versions (amongst other things).

I have similar problems, in my case seem to be related to network connectivity:

Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."

Things to check:

• Is there any chance that your server is not able to respond within some time limit? Like 60 seconds or 4 minutes?
• Is there a possibility that your device is switching networks (WiFi, 3G, VPN)?
• Could someone (client vs. server) be waiting for authentication?

Sorry, no ideas how to fix. Just debugging this, trying to find out what the problem is (-1021, -1001, -1009)

Update: Google search was very kind to find this:

• -1001 TimedOut - it took longer than the timeout which was alotted.
• -1003 CannotFindHost - the host could not be found.
• -1004 CannotConnectToHost - the host would not let us establish a connection.

Zend Guard does not support php 5.5 and is easy to reverse, go for http://www.ioncube.com for obfuscation. http://wwww.phplicengine.com can license the scripts remotely or locally.

I hope that you will find helpfull the following trick.

You can bind both the events

combobox.SelectionChanged += OnSelectionChanged;
combobox.DropDownOpened += OnDropDownOpened;

And force selected item to null inside the OnDropDownOpened

private void OnDropDownOpened(object sender, EventArgs e)
{
    combobox.SelectedItem = null;
}

And do what you need with the item inside the OnSelectionChanged. The OnSelectionChanged will be raised every time you will open the combobox, but you can check if SelectedItem is null inside the method and skip the command

private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        if (combobox.SelectedItem != null)
        {
           //Do something with the selected item
        }
    }

Koala_dev's answer will work, but in case you are wondering this is the reason why it works:

.
q.html, body {              <--applying this css block to everything in the
                             html code.

q.max-width: 100%;          <--all items created must not exceed 100% of the 
                             users screen size. (no items can be off the page 
                             requiring scroll)

q.overflow-x: hidden;       <--anything that occurs off the X axis of the 
                             page is hidden, so that you wont see it going 
                             off the page.     

.

The typical pattern is to check out the root project folder (=the one containing a file called ".project") from SVN using eclipse's svn integration (SVN repository exploring perspective). The project is then recognized automatically.

Try this:

git reset --hard HEAD
git pull

It should do what you want.

There is a discussion on http://blogs.msdn.com/marcelolr/archive/2009/03/13/fast-way-to-convert-xmldocument-into-xdocument.aspx

It seems that reading an XDocument via an XmlNodeReader is the fastest method. See the blog for more details.

Looking at most of the replies, they seem overly complicated. Angular has built in mechanisms to unregister.

Use the deregistration function returned by $on :

// Register and get a handle to the listener
var listener = $scope.$on('someMessage', function () {
    $log.log("Message received");
});

// Unregister
$scope.$on('$destroy', function () {
    $log.log("Unregistering listener");
    listener();
});

If you paste the listing into your word processor instead of Notepad, (since each file name is in quotation marks with the full path name), you can highlight all the stuff you don't want on the first file, then use Find and Replace to replace every occurrence of that with nothing. Same with the ending quote (").

It makes a nice clean list of file names.

Press Ctrl+Shift and double-click a shortcut to run as an elevated process.

Works from the start menu as well.

Since Rails 4 you can do:

User.find_by(name: 'Bob')

which is the equivalent find_by_name in Rails 3.

Use #where when #find and #find_by are not enough.

for(<first part>; <second part>; <third part>)
{
    DoStuff();
}

This code is evaluated like this:

1. Run <first part>
2. If <second part> is false, skip to the end
3. DoStuff();
4. Run <third part>
5. Goto 2

So for your example:

for (int i = 0; i < 8; i++)
{
    DoStuff();
}

1. Set i to 0.
2. If i is not less than 8, skip to the end.
3. DoStuff();
4. i++
5. Goto 2

So the loop runs one time with i set to each value from 0 to 7. Note that i is incremented to 8, but then the loop ends immediately afterwards; it does not run with i set to 8.

Set the margin for body at 0 and that will fix it.

body {
   margin: 0;
}

A simple way to do so is to add the below code (for Seaborn):

for p in splot.patches:
    splot.annotate(format(p.get_height(), '.1f'), 
                   (p.get_x() + p.get_width() / 2., p.get_height()), 
                   ha = 'center', va = 'center', 
                   xytext = (0, 9), 
                   textcoords = 'offset points') 

Example :

splot = sns.barplot(df['X'], df['Y'])
# Annotate the bars in plot
for p in splot.patches:
    splot.annotate(format(p.get_height(), '.1f'), 
                   (p.get_x() + p.get_width() / 2., p.get_height()), 
                   ha = 'center', va = 'center', 
                   xytext = (0, 9), 
                   textcoords = 'offset points')    
plt.show()

The reason not to synchronize on this is that sometimes you need more than one lock (the second lock often gets removed after some additional thinking, but you still need it in the intermediate state). If you lock on this, you always have to remember which one of the two locks is this; if you lock on a private Object, the variable name tells you that.

From the reader's viewpoint, if you see locking on this, you always have to answer the two questions:

1. what kind of access is protected by this?
2. is one lock really enough, didn't someone introduce a bug?

An example:

class BadObject {
    private Something mStuff;
    synchronized setStuff(Something stuff) {
        mStuff = stuff;
    }
    synchronized getStuff(Something stuff) {
        return mStuff;
    }
    private MyListener myListener = new MyListener() {
        public void onMyEvent(...) {
            setStuff(...);
        }
    }
    synchronized void longOperation(MyListener l) {
        ...
        l.onMyEvent(...);
        ...
    }
}

If two threads begin longOperation() on two different instances of BadObject, they acquire their locks; when it's time to invoke l.onMyEvent(...), we have a deadlock because neither of the threads may acquire the other object's lock.

In this example we may eliminate the deadlock by using two locks, one for short operations and one for long ones.

You are "tainting" the canvas by loading from a cross origins domain. Check out this MDN article:

https://developer.mozilla.org/en-US/docs/HTML/CORS_Enabled_Image

javadocs show that the parse method is overloaded.

Create a StringStream or InputSource using your string XML and you should be set.

There is no mention about nine-patch files here. Yes, you have to create the file, however it's quite easy job and it's really "cross-version and transparency supporting" solution. If the file is placed to the drawable-nodpi directory, it works px based, and in the drawable-mdpi works approximately as dp base (thanks to resample).

Example file for the original question (border-right:1px solid red;) is here:

http://ge.tt/517ZIFC2/v/3?c

Just place it to the drawable-nodpi directory.

you can declare a Numpy array dynamically for 1 dimension as shown below:

import numpy as np

n = 2
new_table = np.empty(shape=[n,1])

new_table[0,0] = 2
new_table[1,0] = 3
print(new_table)

The above example assumes we know we need to have 1 column but we want to allocate the number of rows dynamically (in this case the number or rows required is equal to 2)

output is shown below:

[[2.] [3.]]

I had a similar error. The problem had to do with the child and parent table not having the same charset and collation. This can be fixed by appending ENGINE = InnoDB DEFAULT CHARACTER SET = utf8;

CREATE TABLE IF NOT EXISTS `country` (`id` INT(11) NOT NULL AUTO_INCREMENT,...) ENGINE = InnoDB DEFAULT CHARACTER SET = utf8;

... on the SQL statement means that there is some missing code.

Just don't set the height property in HighCharts and it will handle it dynamically for you so long as you set a height on the chart's containing element. It can be a fixed number or a even a percent if position is absolute.

Highcharts docs:

By default the height is calculated from the offset height of the containing element

Example: http://jsfiddle.net/wkkAd/149/

#container {
    height:100%;
    width:100%;
    position:absolute;
}

For those scripting tmux, there is a command called rename-window so e.g.

tmux rename-window -t <window> <newname>

$.ajax({
  url:href,
  type:'get',
  success: function(data){
   console.log($(data)); 
  }
});

This console log gets an array like object: [meta, title, ,], very strange

You can use JavaScript:

var doc = document.documentElement.cloneNode()
doc.innerHTML = data
$content = $(doc.querySelector('#content'))

Try this:

$(someElem).html('this<br> has<br> newlines);

try the !important argument to make sure the CSS is not conflicting with any other styles you have specified. Also using a reset.css is good before you add your own styles.

select#wgmstr {
    max-width: 50px;
    min-width: 50px;
    width: 50px !important;
}

or

<select name="wgtmsr" id="wgtmsr" style="width: 50px !important; min-width: 50px; max-width: 50px;">

Push object into your array. Try this:

export class FormComponent implements OnInit {
    name: string;
    empoloyeeID : number;
    empList: Array<{name: string, empoloyeeID: number}> = []; 
    constructor() {}
    ngOnInit() {}
    onEmpCreate(){
        console.log(this.name,this.empoloyeeID);
        this.empList.push({ name: this.name, empoloyeeID: this.empoloyeeID });
        this.name = "";
        this.empoloyeeID = 0;
    }
}

• Best of all: Notepad ++ (Free and helpful with colors and link)
• Average: NetBeans (Normal IDE)
• Not good: Eclipse (It crashes when you don't wait for it)
• Oh and I forget: Don't ever use JDeveloper :D

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

If you know the sting will always be in the same format, first split the string based on . and store the string at the first index in a variable. Then split the string in the second index based on - and store indexes 0, 1 and 2. Finally, split index 2 of the previous array based on . and you should have obtained all of the relevant fields.

Refer to the following snippet:

String[] tmp = pdfName.split(".");
String val1 = tmp[0];
tmp = tmp[1].split("-");
String val2 = tmp[0];
...

As far as I am aware, simply opening the file in write mode without append mode will erase the contents of the file.

ofstream file("filename.txt"); // Without append
ofstream file("filename.txt", ios::app); // with append

The first one will place the position bit at the beginning erasing all contents while the second version will place the position bit at the end-of-file bit and write from there.

It is important to understand that accessors restrict access to variable, but not their content. In ruby, like in some other OO languages, every variable is a pointer to an instance. So if you have an attribute to an Hash, for example, and you set it to be "read only" you always could change its content, but not the content of pointer. Look at this:

irb(main):024:0> class A
irb(main):025:1> attr_reader :a
irb(main):026:1> def initialize
irb(main):027:2> @a = {a:1, b:2}
irb(main):028:2> end
irb(main):029:1> end
=> :initialize
irb(main):030:0> a = A.new
=> #<A:0x007ffc5a10fe88 @a={:a=>1, :b=>2}>
irb(main):031:0> a.a
=> {:a=>1, :b=>2}
irb(main):032:0> a.a.delete(:b)
=> 2
irb(main):033:0> a.a
=> {:a=>1}
irb(main):034:0> a.a = {}
NoMethodError: undefined method `a=' for #<A:0x007ffc5a10fe88 @a={:a=>1}>
        from (irb):34
        from /usr/local/bin/irb:11:in `<main>'

As you can see is possible delete a key/value pair from the Hash @a, as add new keys, change values, eccetera. But you can't point to a new object because is a read only instance variable.

PostgreSQL 13 introduced FORCE option.

DROP DATABASE

DROP DATABASE drops a database ... Also, if anyone else is connected to the target database, this command will fail unless you use the FORCE option described below.

FORCE

Attempt to terminate all existing connections to the target database. It doesn't terminate if prepared transactions, active logical replication slots or subscriptions are present in the target database.

DROP DATABASE db_name WITH (FORCE);

Dictionary is faster than hashtable as dictionary is a generic strong type. Hashtable is slower as it takes object as data type which leads to boxing and unboxing.

The size arguments are in pixels. So, to double your example's marker size the fifth argument to the MarkerImage constructor would be:

new google.maps.Size(42,68)

I find it easiest to let the map API figure out the other arguments, unless I need something other than the bottom/center of the image as the anchor. In your case you could do:

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + pinColor,
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);

If it's a 1 time import, the Import/Export utility in SSMS will probably work the easiest and fastest. SSIS also seems to work better for importing large data sets than a straight INSERT.

BULK INSERT or BCP can also be used to import large record sets.

Another option would be to temporarily remove all indexes and constraints on the table you're importing into and add them back once the import process completes. A straight INSERT that previously failed might work in those cases.

If you're dealing with timeouts or locking/blocking issues when going directly from one database to another, you might consider going from one db into TEMPDB and then going from TEMPDB into the other database as it minimizes the effects of locking and blocking processes on either side. TempDB won't block or lock the source and it won't hold up the destination.

Those are a few options to try.

This was added to the upgrade documentation on Dec 29, 2015, so if you upgraded before then you probably missed it.

When fetching any attribute from the model it checks if that column should be cast as an integer, string, etc.

By default, for auto-incrementing tables, the ID is assumed to be an integer in this method:

https://github.com/laravel/framework/blob/5.2/src/Illuminate/Database/Eloquent/Model.php#L2790

So the solution is:

class UserVerification extends Model
{
    protected $primaryKey = 'your_key_name'; // or null

    public $incrementing = false;

    // In Laravel 6.0+ make sure to also set $keyType
    protected $keyType = 'string';
}

I had a similar issue and ended up with this:

For me this has the advantage that data and annotation are not overlapping.

from matplotlib import pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)

# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
    x = A[ind]
    y = B[ind]
    xPos = x1 + .02 * (x1 - x0)
    yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
    ax.annotate('',#label,
          xy=(x, y), xycoords='data',
          xytext=(xPos, yPos), textcoords='data',
          arrowprops=dict(
                          connectionstyle="arc3,rad=0.",
                          shrinkA=0, shrinkB=10,
                          arrowstyle= '-|>', ls= '-', linewidth=2
                          ),
          va='bottom', ha='left', zorder=19
          )
    ax.text(xPos + .01 * (x1 - x0), yPos,
            '({:.2f}, {:.2f})'.format(x,y),
            transform=ax.transData, va='center')

plt.grid()
plt.show()

Using the text argument in .annotate ended up with unfavorable text positions. Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.

Adding **/bin/ to the .gitignore file did the trick for me (Note: bin folder wasn't added to index).

Your hack of decrementing the count at the end is exactly that -- a hack.

Far better to write your loop correctly in the first place, so it doesn't count the last line twice.

int main() { 
    int number_of_lines = 0;
    std::string line;
    std::ifstream myfile("textexample.txt");

    while (std::getline(myfile, line))
        ++number_of_lines;
    std::cout << "Number of lines in text file: " << number_of_lines;
    return 0;
}

Personally, I think in this case, C-style code is perfectly acceptable:

int main() {
    unsigned int number_of_lines = 0;
    FILE *infile = fopen("textexample.txt", "r");
    int ch;

    while (EOF != (ch=getc(infile)))
        if ('\n' == ch)
            ++number_of_lines;
    printf("%u\n", number_of_lines);
    return 0;
}

Edit: Of course, C++ will also let you do something a bit similar:

int main() {
    std::ifstream myfile("textexample.txt");

    // new lines will be skipped unless we stop it from happening:    
    myfile.unsetf(std::ios_base::skipws);

    // count the newlines with an algorithm specialized for counting:
    unsigned line_count = std::count(
        std::istream_iterator<char>(myfile),
        std::istream_iterator<char>(), 
        '\n');

    std::cout << "Lines: " << line_count << "\n";
    return 0;
}

$lines = array();
while (($line = fgets($file)) !== false)
    array_push($lines, $line);

Obviously, you'll need to create a file handle first and store it in $file.

On top of previous answers, I'd like to raise awareness about the fact that you should use the RAII (Resource Acquisition Is Initialisation) idiom to be safe about handler destruction.

Here is a complete working example:

Interface declaration: Interface.hpp:

class Base {
public:
    virtual ~Base() {}
    virtual void foo() const = 0;
};

using Base_creator_t = Base *(*)();

Shared library content:

#include "Interface.hpp"

class Derived: public Base {
public:
    void foo() const override {}
};

extern "C" {
Base * create() {
    return new Derived;
}
}

Dynamic shared library handler: Derived_factory.hpp:

#include "Interface.hpp"
#include <dlfcn.h>

class Derived_factory {
public:
    Derived_factory() {
        handler = dlopen("libderived.so", RTLD_NOW);
        if (! handler) {
            throw std::runtime_error(dlerror());
        }
        Reset_dlerror();
        creator = reinterpret_cast<Base_creator_t>(dlsym(handler, "create"));
        Check_dlerror();
    }

    std::unique_ptr<Base> create() const {
        return std::unique_ptr<Base>(creator());
    }

    ~Derived_factory() {
        if (handler) {
            dlclose(handler);
        }
    }

private:
    void * handler = nullptr;
    Base_creator_t creator = nullptr;

    static void Reset_dlerror() {
        dlerror();
    }

    static void Check_dlerror() {
        const char * dlsym_error = dlerror();
        if (dlsym_error) {
            throw std::runtime_error(dlsym_error);
        }
    }
};

Client code:

#include "Derived_factory.hpp"

{
    Derived_factory factory;
    std::unique_ptr<Base> base = factory.create();
    base->foo();
}

Note:

• I put everything in header files for conciseness. In real life you should of course split your code between .hpp and .cpp files.
• To simplify, I ignored the case where you want to handle a new/delete overload.

Unirest is the best library I've come across for making HTTP requests from Node. It's aiming at being a multiplatform framework, so learning how it works on Node will serve you well if you need to use an HTTP client on Ruby, PHP, Java, Python, Objective C, .Net or Windows 8 as well. As far as I can tell the unirest libraries are mostly backed by existing HTTP clients (e.g. on Java, the Apache HTTP client, on Node, Mikeal's Request libary) - Unirest just puts a nicer API on top.

Here are a couple of code examples for Node.js:

var unirest = require('unirest')

// GET a resource
unirest.get('http://httpbin.org/get')
  .query({'foo': 'bar'})
  .query({'stack': 'overflow'})
  .end(function(res) {
    if (res.error) {
      console.log('GET error', res.error)
    } else {
      console.log('GET response', res.body)
    }
  })

// POST a form with an attached file
unirest.post('http://httpbin.org/post')
  .field('foo', 'bar')
  .field('stack', 'overflow')
  .attach('myfile', 'examples.js')
  .end(function(res) {
    if (res.error) {
      console.log('POST error', res.error)
    } else {
      console.log('POST response', res.body)
    }
  })

require(name)

It will return bolean true/false

The name which is passed as parameter to the require, ruby will try to find the source file with that name in your load path. The require method will return ‘false’ if you try to load the same library after the first time. The require method only needs to be used if library you are loading is defined in a separate file. So it keeps track of whether that library was already loaded or not.

include module_name

Suppose if you have some methods that you need to have in two different classes. Then you don't have to write them in both the classes. Instead what you can do is, define it in module. And then include this module in other classes. It is provided by Ruby just to ensure DRY principle. It’s used to DRY up your code to avoid duplication

I use talib.CORREL for autocorrelation like this, I suspect you could do the same with other packages:

def autocorrelate(x, period):

    # x is a deep indicator array 
    # period of sample and slices of comparison

    # oldest data (period of input array) may be nan; remove it
    x = x[-np.count_nonzero(~np.isnan(x)):]
    # subtract mean to normalize indicator
    x -= np.mean(x)
    # isolate the recent sample to be autocorrelated
    sample = x[-period:]
    # create slices of indicator data
    correls = []
    for n in range((len(x)-1), period, -1):
        alpha = period + n
        slices = (x[-alpha:])[:period]
        # compare each slice to the recent sample
        correls.append(ta.CORREL(slices, sample, period)[-1])
    # fill in zeros for sample overlap period of recent correlations    
    for n in range(period,0,-1):
        correls.append(0)
    # oldest data (autocorrelation period) will be nan; remove it
    correls = np.array(correls[-np.count_nonzero(~np.isnan(correls)):])      

    return correls

# CORRELATION OF BEST FIT
# the highest value correlation    
max_value = np.max(correls)
# index of the best correlation
max_index = np.argmax(correls)

Local classes have already been mentioned, but here is a way to let them appear even more as local functions, using an operator() overload and an anonymous class:

int main() {
    struct {
        unsigned int operator() (unsigned int val) const {
            return val<=1 ? 1 : val*(*this)(val-1);
        }
    } fac;

    std::cout << fac(5) << '\n';
}

I don't advise on using this, it's just a funny trick (can do, but imho shouldn't).

2014 Update:

With the rise of C++11 a while back, you can now have local functions whose syntax is a little reminiscient of JavaScript:

auto fac = [] (unsigned int val) {
    return val*42;
};

My answer is inspired by Jeffrey's answer. Where that answer gives a more abstract solution, I try to provide more concrete steps on how to potentially implement it. This is simply a guide, one that can be implemented more elegantly. For a more detailed example check out this tutorial by MDN web docs.

HTML:

<div id="zoom_here">....</div>

JS

<script>
var dist1=0;
function start(ev) {
           if (ev.targetTouches.length == 2) {//check if two fingers touched screen
               dist1 = Math.hypot( //get rough estimate of distance between two fingers
                ev.touches[0].pageX - ev.touches[1].pageX,
                ev.touches[0].pageY - ev.touches[1].pageY);                  
           }
    
    }
    function move(ev) {
           if (ev.targetTouches.length == 2 && ev.changedTouches.length == 2) {
                 // Check if the two target touches are the same ones that started
               var dist2 = Math.hypot(//get rough estimate of new distance between fingers
                ev.touches[0].pageX - ev.touches[1].pageX,
                ev.touches[0].pageY - ev.touches[1].pageY);
                //alert(dist);
                if(dist1>dist2) {//if fingers are closer now than when they first touched screen, they are pinching
                  alert('zoom out');
                }
                if(dist1<dist2) {//if fingers are further apart than when they first touched the screen, they are making the zoomin gesture
                   alert('zoom in');
                }
           }
           
    }
        document.getElementById ('zoom_here').addEventListener ('touchstart', start, false);
        document.getElementById('zoom_here').addEventListener('touchmove', move, false);
</script>

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

While waiting for read() or write() to/from a file descriptor return, the process will be put in a special kind of sleep, known as "D" or "Disk Sleep". This is special, because the process can not be killed or interrupted while in such a state. A process waiting for a return from ioctl() would also be put to sleep in this manner.

An exception to this is when a file (such as a terminal or other character device) is opened in O_NONBLOCK mode, passed when its assumed that a device (such as a modem) will need time to initialize. However, you indicated block devices in your question. Also, I have never tried an ioctl() that is likely to block on a fd opened in non blocking mode (at least not knowingly).

How another process is chosen depends entirely on the scheduler you are using, as well as what other processes might have done to modify their weights within that scheduler.

Some user space programs under certain circumstances have been known to remain in this state forever, until rebooted. These are typically grouped in with other "zombies", but the term would not be correct as they are not technically defunct.

Change this line:

if (typeof(T) == typeof(string))

For this line:

if (t.GetType() == typeof(string))

Try it like this:

.row-2 ul li {
    margin-top: 15px;
}

Create a Name.bat file that has the following line in it.

taskkill /F /IM wscript.exe /T

Be sure not to overpower your processor. If you're running long scripts, your processor speed changes and script lines will override each other.

While you cannot prevent orientation change from taking effect you can emulate no change as stated in other answers.

First detect device orientation or reorientation and, using JavaScript, add a class name to your wrapping element (in this example I use the body tag).

function deviceOrientation() {
  var body = document.body;
  switch(window.orientation) {
    case 90:
      body.classList = '';
      body.classList.add('rotation90');
      break;
    case -90:
      body.classList = '';
      body.classList.add('rotation-90');
      break;
    default:
      body.classList = '';
      body.classList.add('portrait');
      break;
  }
}
window.addEventListener('orientationchange', deviceOrientation);
deviceOrientation();

Then if the device is landscape, use CSS to set the body width to the viewport height and the body height to the viewport width. And let’s set the transform origin while we’re at it.

@media screen and (orientation: landscape) {
  body {
    width: 100vh;
    height: 100vw;
    transform-origin: 0 0;
  }
}

Now, reorient the body element and slide (translate) it into position.

body.rotation-90 {
  transform: rotate(90deg) translateY(-100%);
}
body.rotation90 {
  transform: rotate(-90deg) translateX(-100%);
}

Div tags are easy to spot for me. Just download the file, scan it or so with netbeans, then continue debugging it. Or you can use the Google chrome developer kit, and view the page source. I'm a bit of a weird developer, I don't always use the "best" stuff. But it works for me.

I'll link you with some developer stuff I use

Those are just a few of the good ones out there. I'm open to more suggestions to this list :D

Happy programming

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

This can be done with PIL. First, install it, then you can take a full screenshot like this:

import PIL.ImageGrab

im = PIL.ImageGrab.grab()
im.show()

The view (blade template): Inside the loop you can retrieve whatever column you looking for

 @foreach ($products as $product)
   {{$product->sku}}
 @endforeach

In case it is not possible to bind the addTarget to your UITextField, I advise you to bind one of them as suggested above, and insert the code for execution at the end of the shouldChangeCharactersIn method.

nameTextField.addTarget(self, action: #selector(RegistrationViewController.textFieldDidChange(_:)), for: .editingChanged)

@objc func textFieldDidChange(_ textField: UITextField) {
    if phoneNumberTextField.text!.count == 17 && nameTextField.text!.count > 0 {
        continueButtonOutlet.backgroundColor = UIColor(.green)
    } else {
        continueButtonOutlet.backgroundColor = .systemGray
    }
}

And in call in shouldChangeCharactersIn func.

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {

    guard let text = textField.text else {
        return true
    }
    let lastText = (text as NSString).replacingCharacters(in: range, with: string) as String

    if phoneNumberTextField == textField {
        textField.text = lastText.format("+7(NNN)-NNN-NN-NN", oldString: text)
        textFieldDidChange(phoneNumberTextField)
        return false
    }
    return true
}

SQLite does not contain regular expression functionality by default.

It defines a REGEXP operator, but this will fail with an error message unless you or your framework define a user function called regexp(). How you do this will depend on your platform.

If you have a regexp() function defined, you can match an arbitrary integer from a comma-separated list like so:

... WHERE your_column REGEXP "\b" || your_integer || "\b";

But really, it looks like you would find things a whole lot easier if you normalised your database structure by replacing those groups within a single column with a separate row for each number in the comma-separated list. Then you could not only use the = operator instead of a regular expression, but also use more powerful relational tools like joins that SQL provides for you.

As the default configuration of Postgres, a user called postgres is made and the user postgres has full super admin access to entire PostgreSQL instance running on your OS.

sudo -u postgres psql

The above command gets you the psql command line interface in admin mode.

Creating user

sudo -u postgres createuser <username>

Creating Database

 sudo -u postgres createdb <dbname>

NOTE: < > are not to be used while writing command, they are used just to signify the variables

This error also occurs on Android 8+ when Service.startForeground(int id, Notification notification) is called while id is set to 0.
