The main differences are:

1) OFFLINE index rebuild is faster than ONLINE rebuild.

2) Extra disk space required during SQL Server online index rebuilds.

3) SQL Server locks acquired with SQL Server online index rebuilds.

• This schema modification lock blocks all other concurrent access to the table, but it is only held for a very short period of time while the old index is dropped and the statistics updated.

I meet this error too when I run a wordpress on my Fedora system.

I googled it, and find a way to fix this.

Maybe this will help you too.

1. check mysql config : my.cnf

    cat /etc/my.cnf | grep tmpdir
   

   I can't see anything in my my.cnf

2. add tmpdir=/tmp to my.cnf under [mysqld]

3. restart web/app and mysql server

   /etc/init.d/mysqld restart

In Java, you can use char value with ":

char quotes ='"';

String strVar=quotes+"ROM"+quotes;

I was given access to a database, but not the table where my query was being stored in.

Inspired by @marc_s answer, I had a look at HeidiSQL which is a Windows program that can deal with MySQL, SQL Server, and PostgreSQL.

I found that it can also search a database for a string.

It will search each table and give you how many times it found the string per table!

There is an easy tool for timing. https://github.com/RalphMao/PyTimer

It can work like a decorator:

from pytimer import Timer
@Timer(average=False)      
def matmul(a,b, times=100):
    for i in range(times):
        np.dot(a,b)        

Output:

matmul:0.368434
matmul:2.839355

It can also work like a plug-in timer with namespace control(helpful if you are inserting it to a function which has a lot of codes and may be called anywhere else).

timer = Timer()                                           
def any_function():                                       
    timer.start()                                         

    for i in range(10):                                   

        timer.reset()                                     
        np.dot(np.ones((100,1000)), np.zeros((1000,500)))
        timer.checkpoint('block1')                        

        np.dot(np.ones((100,1000)), np.zeros((1000,500)))
        np.dot(np.ones((100,1000)), np.zeros((1000,500)))
        timer.checkpoint('block2')                        
        np.dot(np.ones((100,1000)), np.zeros((1000,1000)))

    for j in range(20):                                   
        np.dot(np.ones((100,1000)), np.zeros((1000,500)))
    timer.summary()                                       

for i in range(2):                                        
    any_function()                                        

Output:

========Timing Summary of Default Timer========

block1:0.032529
========Timing Summary of Default Timer========

Hope it will help

1 - Treat functions as objects.

2 - The apply method is similar to __call __ in Python, which allows you to use an instance of a given class as a function.

A POSIX compliant answer. Notice the use of /bin/sh instead of /bin/bash. (It does work with bash, but it does not require bash.)

#!/bin/sh
stty -echo
printf "Password: "
read PASSWORD
stty echo
printf "\n"

is it still actual?

As I can see you wrote <target depends="build-subprojects,build-project" name="build"/>, then you wrote <target name="build-subprojects"/> (it does nothing). Could it be a reason? Does this <echo message="${ant.project.name}: ${ant.file}"/> print appropriate message? If no then target is not running. Take a look at the next link http://www.sqaforums.com/showflat.php?Number=623277

I found that the new version of PhpMyAdmin put the 'config.inc.php' files in /var/lib/phpmyadmin/

I spend much time in the wrong dir (/usr/share) as this is where all the files also is located, but changes are not reflected.

After putting my settings in

/var/lib/phpmyadmin/config.inc.php

They worked

Extracting a specific folder (directory) within war file:

# unzip <war file> '<folder to extract/*>' -d <destination path> 
unzip app##123.war 'some-dir/*' -d extracted/

You get ./extracted/some-dir/ as a result.

If your media query condition is true then your CSS with that condition will work. That means CSS within your media query's condition pixel size will effect, or else if the condition will fail that mean if the device's width is greater than 1024px than your CSS will not work.Because your media query condition false.

max-width is your max CSS limit till that width.

pip install django-cors-headers

and then add it to your installed apps:

INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)

You will also need to add a middleware class to listen in on responses:

MIDDLEWARE_CLASSES = (
    ...
    'corsheaders.middleware.CorsMiddleware',  
    'django.middleware.common.CommonMiddleware',  
    ...
)

CORS_ORIGIN_ALLOW_ALL = True # If this is used then `CORS_ORIGIN_WHITELIST` will not have any effect
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_WHITELIST = [
    'http://localhost:3030',
] # If this is used, then not need to use `CORS_ORIGIN_ALLOW_ALL = True`
CORS_ORIGIN_REGEX_WHITELIST = [
    'http://localhost:3030',
]

read the official documentation can resolve almost all problem

I had the same issue with importing matplotlib.pylab with Python 3.5.1 on Win 64. Installing the Visual C++ Redistributable für Visual Studio 2015 from this links: https://www.microsoft.com/en-us/download/details.aspx?id=48145 fixed the missing DLLs.

I find it better and easier than downloading and pasting DLLs.

I just use ramda, for resolve the same problem, i need to know what is changed in new object. So here my design.

const oldState = {id:'170',name:'Ivab',secondName:'Ivanov',weight:45};
const newState = {id:'170',name:'Ivanko',secondName:'Ivanov',age:29};

const keysObj1 = R.keys(newState)

const filterFunc = key => {
  const value = R.eqProps(key,oldState,newState)
  return {[key]:value}
}

const result = R.map(filterFunc, keysObj1)

result is, name of property and it's status.

[{"id":true}, {"name":false}, {"secondName":true}, {"age":false}]

if you compile in C change

for (int i=0;i<10;i++) { ..

to

int i;
for (i=0;i<10;i++) { ..

You can also compile with the C99 switch set. Put -std=c99 in the compilation line:

gcc -std=c99 foo.c -o foo

BigDecimal isn't a primitive, so you cannot use the <, > operators. However, since it's a Comparable, you can use the compareTo(BigDecimal) to the same effect. E.g.:

public class Domain {
    private BigDecimal unitPrice;

    public boolean isCheaperThan(BigDecimal other) {
        return unitPirce.compareTo(other.unitPrice) < 0;
    }

    // etc...
}

This is older but placing this here for my reference too. boto3.resource is just implementing the default Session, you can pass through boto3.resource session details.

Help on function resource in module boto3:

resource(*args, **kwargs)
    Create a resource service client by name using the default session.

    See :py:meth:`boto3.session.Session.resource`.

https://github.com/boto/boto3/blob/86392b5ca26da57ce6a776365a52d3cab8487d60/boto3/session.py#L265

you can see that it just takes the same arguments as Boto3.Session

import boto3
S3 = boto3.resource('s3', region_name='us-west-2', aws_access_key_id=settings.AWS_SERVER_PUBLIC_KEY, aws_secret_access_key=settings.AWS_SERVER_SECRET_KEY)
S3.Object( bucket_name, key_name ).delete()

I will just leave it here, just rewrote the code above using numpy, maybe somebody finds it useful:

def ray_tracing_numpy(x,y,poly):
    n = len(poly)
    inside = np.zeros(len(x),np.bool_)
    p2x = 0.0
    p2y = 0.0
    xints = 0.0
    p1x,p1y = poly[0]
    for i in range(n+1):
        p2x,p2y = poly[i % n]
        idx = np.nonzero((y > min(p1y,p2y)) & (y <= max(p1y,p2y)) & (x <= max(p1x,p2x)))[0]
        if p1y != p2y:
            xints = (y[idx]-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
        if p1x == p2x:
            inside[idx] = ~inside[idx]
        else:
            idxx = idx[x[idx] <= xints]
            inside[idxx] = ~inside[idxx]    

        p1x,p1y = p2x,p2y
    return inside    

Wrapped ray_tracing into

def ray_tracing_mult(x,y,poly):
    return [ray_tracing(xi, yi, poly[:-1,:]) for xi,yi in zip(x,y)]

Tested on 100000 points, results:

ray_tracing_mult 0:00:00.850656
ray_tracing_numpy 0:00:00.003769

As others have answered… div is a “block element” (now redefined as Flow Content) and span is an “inline element” (Phrasing Content). Yes, you may change the default presentation of these elements, but there is a difference between “flow” versus “block”, and “phrasing” versus “inline”.

An element classified as flow content can only be used where flow content is expected, and an element classified as phrasing content can be used where phrasing content is expected. Since all phrasing content is flow content, a phrasing element can also be used anywhere flow content is expected. The specs provide more detailed info.

All phrasing elements, such as strong and em, can only contain other phrasing elements: you can’t put a table inside a cite for instance. Most flow content such as div and li can contain all types of flow content (as well as phrasing content), but there are a few exceptions: p, pre, and th are examples of non-phrasing flow content (“block elements”) that can only contain phrasing content (“inline elements”). And of course there are the normal element restrictions such as dl and table only being allowed to contain certain elements.

While both div and p are non-phrasing flow content, the div can contain other flow content children (including more divs and ps). On the other hand, p may only contain phrasing content children. That means you can’t put a div inside a p, even though both are non-phrasing flow elements.

Now here’s the kicker. These semantic specifications are unrelated to how the element is displayed. Thus, if you have a div inside a span, you will get a validation error even if you have span {display: block;} and div {display: inline;} in your CSS.

The behavior is undefined from the language point of view. Consider that different platforms can have different constraints in memory alignment and endianness. The code in a big endian versus a little endian machine will update the values in the struct differently. Fixing the behavior in the language would require all implementations to use the same endianness (and memory alignment constraints...) limiting use.

If you are using C++ (you are using two tags) and you really care about portability, then you can just use the struct and provide a setter that takes the uint32_t and sets the fields appropriately through bitmask operations. The same can be done in C with a function.

Edit: I was expecting AProgrammer to write down an answer to vote and close this one. As some comments have pointed out, endianness is dealt in other parts of the standard by letting each implementation decide what to do, and alignment and padding can also be handled differently. Now, the strict aliasing rules that AProgrammer implicitly refers to are a important point here. The compiler is allowed to make assumptions on the modification (or lack of modification) of variables. In the case of the union, the compiler could reorder instructions and move the read of each color component over the write to the colour variable.

An example of how to use with offset.

_x000D_

  const firstTouch = getTouch(e);_x000D_
_x000D_
  xDown = firstTouch.clientX;_x000D_
  yDown = firstTouch.clientY;_x000D_
});_x000D_
_x000D_
window.addEventListener('touchend', e => {_x000D_
  if (!xDown || !yDown) {_x000D_
    return;_x000D_
  }_x000D_
_x000D_
  const {_x000D_
    clientX: xUp,_x000D_
    clientY: yUp_x000D_
  } = getTouch(e);_x000D_
  const xDiff = xDown - xUp;_x000D_

  const yDiffAbs = Math.abs(yDown - yUp);_x000D_
_x000D_
  // at least <offset> are a swipe_x000D_
  if (Math.max(xDiffAbs, yDiffAbs) < offset ) {_x000D_
    return;_x000D_

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

I ran into the same issue, but then did the following, and my issue was resolved:

• updated Gradle
• installed the latest version of Android studio (mine was out of date)

And that solved my problem.

Note: It also helped me to click on the event log, because it has more detailed info about errors. https://developer.android.com/studio/releases/gradle-plugin#updating-plugin also has great info.

For that you need reflection in C/C++ language, that doesn't exists. You need to have some meta data describing the structure of your classes (members, inherited base classes). For the moment C/C++ compilers doesn't provide automatically that information in built binaries.

I had the same idea in mind, and I used GCC XML project to get this information. It outputs XML data describing class structures. I have built a project and I'm explaining some key points in this page :

Serialization is easy, but we have to deal with complex data structure implementations (std::string, std::map for example) that play with allocated buffers. Deserialization is more complex and you need to rebuild your object with all its members, plus references to vtables ... a painful implementation.

For example you can serialize like that :

    // Random class initialization
    com::class1* aObject = new com::class1();

    for (int i=0; i<10; i++){
            aObject->setData(i,i);
    }      

    aObject->pdata = new char[7];
    for (int i=0; i<7; i++){
            aObject->pdata[i] = 7-i;
    }
    // dictionary initialization
    cjson::dictionary aDict("./data/dictionary.xml");

    // json transformation
    std::string aJson = aDict.toJson<com::class1>(aObject);

    // print encoded class
    cout << aJson << std::endl ;

To deserialize data it works like that:

    // decode the object
    com::class1* aDecodedObject = aDict.fromJson<com::class1>(aJson);

    // modify data
    aDecodedObject->setData(4,22);

    // json transformation
    aJson = aDict.toJson<com::class1>(aDecodedObject);

    // print encoded class
    cout << aJson << std::endl ;

Ouptuts:

>:~/cjson$ ./main
{"_index":54,"_inner":  {"_ident":"test","pi":3.141593},"_name":"first","com::class0::_type":"type","com::class0::data":[0,1,2,3,4,5,6,7,8,9],"com::classb::_ref":"ref","com::classm1::_type":"typem1","com::classm1::pdata":[7,6,5,4,3,2,1]}

Usually these implementations are compiler dependent (ABI Specification for example), and requires external description to work (GCCXML output), such are not really easy to integrate to projects.

it is esy using time.compareTo(currentTime) < 0

import java.util.Calendar;
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;

public class MyTimerTask {
    static Timer singleTask = new Timer();

    @SuppressWarnings("deprecation")
    public static void main(String args[]) {
        // set download schedule time
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, 9);
        calendar.set(Calendar.MINUTE, 54);
        calendar.set(Calendar.SECOND, 0);
        Date time = (Date) calendar.getTime();
        // get current time
        Date currentTime = new Date();
        // if current time> time schedule set for next day
        if (time.compareTo(currentTime) < 0) {

            time.setDate(time.getDate() + 1);
        } else {
            // do nothing
        }
        singleTask.schedule(new TimerTask() {
            @Override
            public void run() {
                System.out.println("timer task is runing");
            }
        }, time);

    }

}

If you by any chance wants to change the type of your collection you are better served with the Count() extension. This way you don't have to refactor your code (to use Length for instance).

Or, more elegantly: request.path_info

2019 ECMA5 Solution:

const new_arr = arr.reduce((d, i, idx, l) => idx < l.length - 1 ? [...d, i] : d, [])

Non destructive, generic, one-liner and only requires a copy & paste at the end of your array.

If you are after the side effects that happen within the loop, I'd personally go for the range() approach.

If you care about the result of whatever functions you call within the loop, I'd go for a list comprehension or map approach. Something like this:

def f(n):
    return n * n

results = [f(i) for i in range(50)]
# or using map:
results = map(f, range(50))

That's not how you send file on postman. What you did is sending a string which is the path of your image, nothing more.

What you should do is;

1. After setting request method to POST, click to the 'body' tab.
2. Select form-data. At first line, you'll see text boxes named key and value. Write 'image' to the key. You'll see value type which is set to 'text' as default. Make it File and upload your file.
3. Then select 'raw' and paste your json file. Also just next to the binary choice, You'll see 'Text' is clicked. Make it JSON.

You're ready to go.

In your Django view,

from rest_framework.views import APIView
from rest_framework.parsers import MultiPartParser
from rest_framework.decorators import parser_classes

@parser_classes((MultiPartParser, ))
class UploadFileAndJson(APIView):

    def post(self, request, format=None):
        thumbnail = request.FILES["file"]
        info = json.loads(request.data['info'])
        ...
        return HttpResponse()

If nothing of the above helps, check if there is margin-top set on some of the (some levels below) nested DOM element(s).

It will be not recognizable when you inspect body element itself in the debugger. It will only be visible when you unfold several elements nested down in body element in Chrome Dev Tools elements debugger and check if there is one of them with margin-top set.

The below is the upper part of a site screen shot and the corresponding Chrome Dev Tools view when you inspect body tag.

No sign of top margin here and you have resetted all the browser-scpecific CSS properties as per answers above but that unwanted white space is still here.

The following is a view when you inspect the right nested element. It is clearly seen the orange'ish top-margin is set on it. This is the one that causes the white space on top of body element.

On that found element replace margin-top with padding-top if you need space above it and yet not to leak it above the body tag.

Hope that helps :)

My answer will focus on WHEN we can use while/for-else.

At the first glance, it seems there is no different when using

while CONDITION:
    EXPRESSIONS
print 'ELSE'
print 'The next statement'

and

while CONDITION:
    EXPRESSIONS
else:
    print 'ELSE'
print 'The next statement'

Because the print 'ELSE' statement seems always executed in both cases (both when the while loop finished or not run).

Then, it's only different when the statement print 'ELSE' will not be executed. It's when there is a breakinside the code block under while

In [17]: i = 0

In [18]: while i < 5:
    print i
    if i == 2:
        break
    i = i +1
else:
    print 'ELSE'
print 'The next statement'
   ....:
0
1
2
The next statement

If differ to:

In [19]: i = 0

In [20]: while i < 5:
    print i
    if i == 2:
        break
    i = i +1
print 'ELSE'
print 'The next statement'
   ....:
0
1
2
ELSE
The next statement

return is not in this category, because it does the same effect for two above cases.

exception raise also does not cause difference, because when it raises, where the next code will be executed is in exception handler (except block), the code in else clause or right after the while clause will not be executed.

I think, the reason of the error from JDBC driver, you should get suitable JDBC driver for your Oracle db. You can get it from

http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html

Although as other answers here have said you can change the "Output type" to "Windows Application", please be aware that this will mean that you cannot use Console.In as it will become a NullStreamReader.

Console.Out and Console.Error seem to still work fine however.

double click the button and add write // this.close();

This solution reads in an input file line by line, writing each line out to a StringBuilder variable. Whenever it encounters a line that matches what you are looking for, it skips writing that one out. Then it deletes file content and put the StringBuilder variable content.

public void removeLineFromFile(String lineToRemove, File f) throws FileNotFoundException, IOException{
    //Reading File Content and storing it to a StringBuilder variable ( skips lineToRemove)
    StringBuilder sb = new StringBuilder();
    try (Scanner sc = new Scanner(f)) {
        String currentLine;
        while(sc.hasNext()){
            currentLine = sc.nextLine();
            if(currentLine.equals(lineToRemove)){
                continue; //skips lineToRemove
            }
            sb.append(currentLine).append("\n");
        }
    }
    //Delete File Content
    PrintWriter pw = new PrintWriter(f);
    pw.close();

    BufferedWriter writer = new BufferedWriter(new FileWriter(f, true));
    writer.append(sb.toString());
    writer.close();
}

There's a brand new solution found to this problem.

Use all: revert or all: unset.

From MDN:

The revert keyword works exactly the same as unset in many cases. The only difference is for properties that have values set by the browser or by custom stylesheets created by users (set on the browser side).

You need "A css rule available that would remove any styles previously set in the stylesheet for a particular element."

So, if the element have a class name like remove-all-styles:

Eg:

HTML:

<div class="remove-all-styles other-classe another-class"> 
   <!-- content -->
   <p class="text-red other-some-styles"> My text </p>
</div>

With CSS:

  .remove-all-styles {
    all: revert;
  }

Will reset all styles applied by other-class, another-class and all other inherited and applied styles to that div.

Or in your case:

/* mobile first */
.element {
   margin: 0 10;
   transform: translate3d(0, 0, 0);
   z-index: 50;
   display: block;
   etc..
   etc..
}

@media only screen and (min-width: 980px) {
  .element {
    all: revert;
  }
}

Will do.

Here we used one cool CSS property with another cool CSS value.

1. revert

Actually revert, as the name says, reverts that property to its user or user-agent style.

2. all

And when we use revert with the all property, all CSS properties applied to that element will be reverted to user/user-agent styles.

Click here to know difference between author, user, user-agent styles.

For ex: if we want to isolate embedded widgets/components from the styles of the page that contains them, we could write:

.isolated-component {
 all: revert;
}

Which will reverts all author styles (ie developer CSS) to user styles (styles which a user of our website set - less likely scenario) or to user-agent styles itself if no user styles set.

More details here: https://developer.mozilla.org/en-US/docs/Web/CSS/revert

And only issue is the support: only Safari 9.1 and iOS Safari 9.3 have support for revert value at the time of writing.

So I'll say use this style and fallback to any other answers.

Your code is correct, except that you didn't declare the instance pointer outside the class. The inside class declarations of static variables are not considered declarations in C++, however this is allowed in other languages like C# or Java etc.

class Singleton
{
   public:
       static Singleton* getInstance( );
   private:
       Singleton( );
       static Singleton* instance;
};
Singleton* Singleton::instance; //we need to declare outside because static variables are global

You must know that Singleton instance doesn't need to be manually deleted by us. We need a single object of it throughout the whole program, so at the end of program execution, it will be automatically deallocated.

So just to build on the other answers with an example, short-circuiting is crucial in the following defensive checks:

if (foo == null || foo.isClosed()) {
    return;
}

if (bar != null && bar.isBlue()) {
    foo.doSomething();
}

Using | and & instead could result in a NullPointerException being thrown here.

Simply use the "utf-8-sig" codec:

fp = open("file.txt")
s = fp.read()
u = s.decode("utf-8-sig")

That gives you a unicode string without the BOM. You can then use

s = u.encode("utf-8")

to get a normal UTF-8 encoded string back in s. If your files are big, then you should avoid reading them all into memory. The BOM is simply three bytes at the beginning of the file, so you can use this code to strip them out of the file:

import os, sys, codecs

BUFSIZE = 4096
BOMLEN = len(codecs.BOM_UTF8)

path = sys.argv[1]
with open(path, "r+b") as fp:
    chunk = fp.read(BUFSIZE)
    if chunk.startswith(codecs.BOM_UTF8):
        i = 0
        chunk = chunk[BOMLEN:]
        while chunk:
            fp.seek(i)
            fp.write(chunk)
            i += len(chunk)
            fp.seek(BOMLEN, os.SEEK_CUR)
            chunk = fp.read(BUFSIZE)
        fp.seek(-BOMLEN, os.SEEK_CUR)
        fp.truncate()

It opens the file, reads a chunk, and writes it out to the file 3 bytes earlier than where it read it. The file is rewritten in-place. As easier solution is to write the shorter file to a new file like newtover's answer. That would be simpler, but use twice the disk space for a short period.

As for guessing the encoding, then you can just loop through the encoding from most to least specific:

def decode(s):
    for encoding in "utf-8-sig", "utf-16":
        try:
            return s.decode(encoding)
        except UnicodeDecodeError:
            continue
    return s.decode("latin-1") # will always work

An UTF-16 encoded file wont decode as UTF-8, so we try with UTF-8 first. If that fails, then we try with UTF-16. Finally, we use Latin-1 — this will always work since all 256 bytes are legal values in Latin-1. You may want to return None instead in this case since it's really a fallback and your code might want to handle this more carefully (if it can).

The newline character is actually '\n'.

If you're going to use the preprocessor anyway, as per the other answers, then you can make the compiler determine the value of NUM_TYPES automagically:

#define NUM_TYPES (sizeof types / sizeof types[0])
static int types[] = { 
  1,
  2, 
  3, 
  4 };

In case anyone has this problem with Angular 9, this is how I manage to fix it.

I started with the solution with #scrollMe [scrollTop]="scrollMe.scrollHeight" and I got the ExpressionChangedAfterItHasBeenCheckedError error as people mentioned.

In order to fix this one I just add in my ts component:

@Component({
    changeDetection: ChangeDetectionStrategy.OnPush,
...})

 constructor(private cdref: ChangeDetectorRef) {}

 ngAfterContentChecked() {
        this.cdref.detectChanges();
    }

ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'undefined'

"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

I put mine in /Developer/SDKs I had to authenticate to do that…but since there's no consensus I thought that it sounded like a place I'd remember.

in my case, this error is raised due to sequence was not created..

CREATE SEQUENCE  J.SOME_SEQ  MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 NOORDER  NOCYCLE ;

In Python 3.x, raw_input was renamed to input and the Python 2.x input was removed.

This means that, just like raw_input, input in Python 3.x always returns a string object.

To fix the problem, you need to explicitly make those inputs into integers by putting them in int:

x = int(input("Enter a number: "))
y = int(input("Enter a number: "))

Go to this file in: WampFolder\apps\phpmyadmin[phpmyadmin version]\config.inc.php

Usually wamp is in your main hard drive folder C:\wamp\

You will see something like:

$cfg['Servers'][$i]['user'] = 'YOUR USER NAME IS HERE';
$cfg['Servers'][$i]['password'] = 'AND YOU PASSWORD IS HERE';

Try using the password and username that you have on that file.

Same pdo error in sql query while trying to insert into database value from multidimential array:

$sql = "UPDATE test SET field=arr[$s][a] WHERE id = $id";
$sth = $db->prepare($sql);    
$sth->execute();

Extracting array arr[$s][a] from sql query, using instead variable containing it fixes the problem.

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming

Update March 2013

Git 1.8.2 added the possibility to track branches.

"git submodule" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 

If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".

Also see Vogella's tutorial on submodules for general information on submodules.

Note:

git submodule add -b . [URL to Git repo];
                    ^^^

See git submodule man page:

A special value of . is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.

See commit b928922727d6691a3bdc28160f93f25712c565f6:

submodule add: If --branch is given, record it in .gitmodules

This allows you to easily record a submodule.<name>.branch option in .gitmodules when you add a new submodule. With this patch,

$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>

reduces to

$ git submodule add -b <branch> <repository> [<path>]

This means that future calls to

$ git submodule update --remote ...

will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):

A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log within that submodule.

So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:

• cd in the submodule
• git fetch/pull to make sure it has the latest commits on the right branch
• cd back in the parent repo
• add and commit in order to record the new commit of the submodule.

gitslave (that you already looked at) seems to be the best fit, including for the commit operation.

It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).

Other alternatives are detailed here.

Set your PRIMARY KEY as AUTO_INCREMENT.

You could take advantage of JavaScript's setInterval function:

const spanEl = document.querySelector('#spanEl');_x000D_
var interval = setInterval(function() {_x000D_
  spanEl.style.visibility = spanEl.style.visibility === "hidden" ? 'visible' : 'hidden';_x000D_
}, 250);

<span id="spanEl">This text will blink!</span>

An additional note to the get_python_lib function mentioned already: on some platforms different directories are used for platform specific modules (eg: modules that require compilation). If you pass plat_specific=True to the function you get the site packages for platform specific packages.

var value1=$("id1").val();
var value2=$("id2").val();
data:"{'data1':'"+value1+"','data2':'"+value2+"'}"

new Date().toString();

http://www.mkyong.com/java/java-how-to-get-current-date-time-date-and-calender/

Dateformatter can make it to any string you want

With the magic of user-defined literals, we have yet another solution to this. C++14 added a std::string literal operator.

using namespace std::string_literals;
auto const x = "\0" "0"s;

Constructs a string of length 2, with a '\0' character (null) followed by a '0' character (the digit zero). I am not sure if it is more or less clear than the initializer_list<char> constructor approach, but it at least gets rid of the ' and , characters.

What you need to do is this:

int[] list1 = new int[4] { 1, 2, 3, 4};
int[] list2 = new int[4] { 5, 6, 7, 8};
int[] list3 = new int[4] { 1, 3, 2, 1 };
int[] list4 = new int[4] { 5, 4, 3, 2 };

int[][] lists = new int[][] {  list1 ,  list2 ,  list3 ,  list4  };

Another alternative would be to create a List<int[]> type:

List<int[]> data=new List<int[]>(){list1,list2,list3,list4};

There is a new function in C standard for getting a line without specifying its size. getline function allocates string with required size automatically so there is no need to guess about string's size. The following code demonstrate usage:

#include <stdio.h>
#include <stdlib.h>


int main(void)
{
    char *line = NULL;
    size_t len = 0;
    ssize_t read;

    while ((read = getline(&line, &len, stdin)) != -1) {
        printf("Retrieved line of length %zu :\n", read);
        printf("%s", line);
    }

    if (ferror(stdin)) {
        /* handle error */
    }

    free(line);
    return 0;
}

Here is an example of using super():

#New-style classes inherit from object, or from another new-style class
class Dog(object):

    name = ''
    moves = []

    def __init__(self, name):
        self.name = name

    def moves_setup(self):
        self.moves.append('walk')
        self.moves.append('run')

    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super(Superdog, self).moves_setup()
        self.moves.append('fly')

dog = Superdog('Freddy')
print dog.name # Freddy
dog.moves_setup()
print dog.get_moves() # ['walk', 'run', 'fly']. 
#As you can see our Superdog has all moves defined in the base Dog class

It is also worth to mention, that if you DO NOT intent to modify the values of the list, it is possible (and better) to use the const_iterator, as follows:

for (std::list<Student>::const_iterator it = data.begin(); it != data.end(); ++it){
    // do whatever you wish but don't modify the list elements
    std::cout << it->name;
}

each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.

• Ensure that every from input has a totaly unique name, so that when the form gets submitted back to to component tree that rendered it, it is easy to tell where each component can read its value form.
• The JSF component can generate javascript that submitts back to the serer, the generated javascript knows where each component is bound too, because it was generated by the component.

• For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.

  http:..../somelink?componentId=123 would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123

The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

You can use C#'s null coalescing operator

return accountNumber ?? string.Empty;

$('#divID').css("background-image", "url(/myimage.jpg)");  

Should do the trick, just hook it up in a click event on the element

$('#divID').click(function()
{
  // do my image switching logic here.
});

Note if you are on certain shared hosting sites like Dreamhost you can't disable PHP output buffering at all without going through different routes:

Changing the output buffer cache If you are using PHP FastCGI, the PHP functions flush(), ob_flush(), and ob_implicit_flush() will not function as expected. By default, output is buffered at a higher level than PHP (specifically, by the Apache module mod_deflate which is similar in form/function to mod_gzip).

If you need unbuffered output, you must either use CGI (instead of FastCGI) or contact support to request that mod_deflate is disabled for your site.

https://help.dreamhost.com/hc/en-us/articles/214202188-PHP-overview

Another way is using a SQL Server built-in feature named Client Statistics which is accessible through Menu > Query > Include Client Statistics.

You can run each query in separated query window and compare the results which is given in Client Statistics tab just beside the Messages tab.

For example in image below it shows that the average time elapsed to get the server reply for one of my queries is 39 milliseconds.

You can read all 3 ways for acquiring execution time in here. You may even need to display Estimated Execution Plan ctrlL for further investigation about your query.

Try this

if(!jsonObj.isNull("club")){
    jsonObj.getString("club");
}

"Last day of month" is actually "First day of *next* month, minus 1". So here's what I use, no need for "DaysInMonth" method:

public static DateTime FirstDayOfMonth(this DateTime value)
{
    return new DateTime(value.Year, value.Month, 1);
}

public static DateTime LastDayOfMonth(this DateTime value)
{
    return value.FirstDayOfMonth()
        .AddMonths(1)
        .AddMinutes(-1);
}

NOTE: The reason I use AddMinutes(-1), not AddDays(-1) here is because usually you need these date functions for reporting for some date-period, and when you build a report for a period, the "end date" should actually be something like Oct 31 2015 23:59:59 so your report works correctly - including all the data from last day of month.

I.e. you actually get the "last moment of the month" here. Not Last day.

OK, I'm going to shut up now.

Use WORKSPACE environment variable to change workspace directory.

If doing using Jenkinsfile, use following code :

dir("${env.WORKSPACE}/aQA"){
    sh "pwd"
}

echo $this->db->select('title, content, date')->get_compiled_select();

The jQuery blog, jQuery 3.1.1 Released!, says,

Slim build

Sometimes you don’t need ajax, or you prefer to use one of the many standalone libraries that focus on ajax requests. And often it is simpler to use a combination of CSS and class manipulation for all your web animations. Along with the regular version of jQuery that includes the ajax and effects modules, we’ve released a “slim” version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code. The size of jQuery is very rarely a load performance concern these days, but the slim build is about 6k gzipped bytes smaller than the regular version – 23.6k vs 30k.

You could use replace to fix your string. The following will return everything before a "(" and also strip all leading and trailing whitespace. If the string starts with a "(" it will just leave it as is.

str = "manchester united (with nice players)"
matched = str.match(/.*(?=\()/)
str.replace(matched[0].strip) if matched

position(). E.G.:

<countNo><xsl:value-of select="position()" /></countNo>

This exception will come in case your server is based on JDK 7 and your client is on JDK 6 and using SSL certificates. In JDK 7 sslv2hello message handshaking is disabled by default while in JDK 6 sslv2hello message handshaking is enabled. For this reason when your client trying to connect server then a sslv2hello message will be sent towards server and due to sslv2hello message disable you will get this exception. To solve this either you have to move your client to JDK 7 or you have to use 6u91 version of JDK. But to get this version of JDK you have to get the MOS (My Oracle Support) Enterprise support. This patch is not public.

Think of a jar file as the root of a directory structure. Yes, you need to add them all separately.

Strict equality operator:-

We can check null by ===

if ( value === null ){

}

Just by using if

if( value ) {

}

will evaluate to true if value is not:

• null
• undefined
• NaN
• empty string ("")
• false
• 0

Just like that: (Swift 4.2.1)

UISwipeGestureRecognizer.Direction.init(
  rawValue: UISwipeGestureRecognizer.Direction.left.rawValue |
            UISwipeGestureRecognizer.Direction.right.rawValue |
            UISwipeGestureRecognizer.Direction.up.rawValue |
            UISwipeGestureRecognizer.Direction.down.rawValue
)

If you are using Visual Studio with NTVS, you can set the environment variables on the project properties page:

As you can see, the Configuration and Platform dropdowns are disabled (I haven't looked too far into why this is), but if you edit your .njsproj file as follows:

  <PropertyGroup Condition=" '$(Configuration)' == 'Debug' ">
    <DebugSymbols>true</DebugSymbols>
    <Environment>NODE_ENV=development</Environment>
  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)' == 'Release' ">
    <DebugSymbols>true</DebugSymbols>
    <Environment>NODE_ENV=production</Environment>
  </PropertyGroup>

The 'Debug / Release' dropdown will then control how the variable is set before starting Node.js.

Some months ago I ran into an odd situation where I also needed to send some Json-formatted date back to my controller. Here's what I came up with after pulling my hair out:

My class looks like this :

public class NodeDate
{
    public string nodedate { get; set; }
}
public class NodeList1
{
    public List<NodeDate> nodedatelist { get; set; }
}

and my c# code as follows :

        public string getTradeContribs(string Id, string nodedates)
    {            
        //nodedates = @"{""nodedatelist"":[{""nodedate"":""01/21/2012""},{""nodedate"":""01/22/2012""}]}";  // sample Json format
        System.Web.Script.Serialization.JavaScriptSerializer ser = new System.Web.Script.Serialization.JavaScriptSerializer();
        NodeList1 nodes = (NodeList1)ser.Deserialize(nodedates, typeof(NodeList1));
        string thisDate = "";
        foreach (var date in nodes.nodedatelist)
        {  // iterate through if needed...
            thisDate = date.nodedate;
        }   
    }

and so I was able to Deserialize my nodedates Json object parameter in the "nodes" object; naturally of course using the class "NodeList1" to make it work.

I hope this helps.... Bob

You need to prevent the default event (following the link), otherwise your link will load a new page:

    $(document).ready(function(){
        $('.play_navigation a').click(function(e){
            e.preventDefault();
            console.log("this is the click");
        });
    });

As pointed out in comments, if your link has no href, then it's not a link, use something else.

Not working? Your code is A MESS! and ready() events everywhere... clean it, put all your scripts in ONE ready event and then try again, it will very likely sort things out.

for (int i = 0; i < list.size(); i++) {
  for (int j = i+1; j < list.size(); j++) {
    // compare list.get(i) and list.get(j)
  }
}

Another thing you can check here is the actual command that is being passed to the JVM and make sure it looks OK. Scroll to the top of your Run console, it should be the first line.

Spaces in your Run Configuration VM Options field will malform the app startup command and can result in this error message

-DsomeArgument="arg with space must be quoted"

You are absolutely right, supporting completely stateless interactions with the server does put an additional burden on the client. However, if you consider scaling an application, the computation power of the clients is directly proportional to the number of clients. Therefore scaling to high numbers of clients is much more feasible.

As soon as you put a tiny bit of responsibility on the server to manage some information related to a specific client's interactions, that burden can quickly grow to consume the server.

It's a trade off.

Deleting .vs folder inside solution folder fixed the slowness for me in VS2019.

I ended up keeping Link and adding the reload to the Link's onClick event with a timeout like this:

function refreshPage() {
    setTimeout(()=>{
        window.location.reload(false);
    }, 500);
    console.log('page to reload')
}

<Link to={{pathname:"/"}} onClick={refreshPage}>Home</Link>

without the timeout, the refresh function would run first

.text{
   background: #ccc;
   position: relative;
   float: left;
   text-align: center;
   width: 400px;
   line-height: 80px;
   font-size: 24px;
   color: #000;
   float: left;
 }

Yes we can work without body-parser. When you don't use that you get the raw request, and your body and headers are not in the root object of request parameter . You will have to individually manipulate all the fields.

Or you can use body-parser, as the express team is maintaining it .

What body-parser can do for you: It simplifies the request.
How to use it: Here is example:

Install npm install body-parser --save

This how to use body-parser in express:

const express = require('express'),
      app = express(),
      bodyParser = require('body-parser');

// support parsing of application/json type post data
app.use(bodyParser.json());

//support parsing of application/x-www-form-urlencoded post data
app.use(bodyParser.urlencoded({ extended: true }));

Link.

https://github.com/expressjs/body-parser.

And then you can get body and headers in root request object . Example

app.post("/posturl",function(req,res,next){
    console.log(req.body);
    res.send("response");
})

Reflection can take you from an object to a dictionary by iterating over the properties.

To go the other way, you'll have to use a dynamic ExpandoObject (which, in fact, already inherits from IDictionary, and so has done this for you) in C#, unless you can infer the type from the collection of entries in the dictionary somehow.

So, if you're in .NET 4.0 land, use an ExpandoObject, otherwise you've got a lot of work to do...

If you want the logo to take space, you are probably better of floating it left and then moving down the content using margin, sort of like this:

#logo {
    float: left;
    margin: 0 10px 10px 20px;
}

#content {
    margin: 10px 0 0 10px;
}

or whatever margin you want.

The conversion fails (java.lang.ClassCastException: java.lang.String cannot be cast to java.util.ArrayList) because you have surely some objects that are not ArrayList. verify the types of your different objects.

Not exactly what you're looking for, but I've found this quite helpful:

git add -AN

Will add all files to the index, but without their content. Files that were untracked now behave as if they were tracked. Their content will be displayed in git diff, and you can add then interactively with git add -p.

Dir has also shorter syntax to get an array of all files from directory:

Dir['dir/to/files/*'].each do |fname|
    # do something with fname
end

you can use regular expressions to identify the last comma (,) and replace it with " " as follow:

if(fieldName.endsWith(","))
{                           
fieldName = fieldName.replace(/,([^,]*)$/," ");
}

I’d use tr:

tr < file-with-nulls -d '\000' > file-without-nulls

If you are wondering if input redirection in the middle of the command arguments works, it does. Most shells will recognize and deal with I/O redirection (<, >, …) anywhere in the command line, actually.

The expression a == b should do the job.

You can't import classes from the default package. You should avoid using the default package except for very small example programs.

From the Java language specification:

It is a compile time error to import a type from the unnamed package.

The DataRow has also an indexer:

Object cellValue = dt.Rows[i][j];

But i would prefer the strongly typed Field extension method which also supports nullable types:

int number = dt.Rows[i].Field<int>(j);

or even more readable and less error-prone with the name of the column:

double otherNumber = dt.Rows[i].Field<double>("DoubleColumn");

For primitive types (e.g. numbers, booleans, strings, etc.), there is no difference between toBe and toEqual; either one will work for 5, true, or "the cake is a lie".

To understand the difference between toBe and toEqual, let's imagine three objects.

var a = { bar: 'baz' },
    b = { foo: a },
    c = { foo: a };

Using a strict comparison (===), some things are "the same":

> b.foo.bar === c.foo.bar
true

> b.foo.bar === a.bar
true

> c.foo === b.foo
true

But some things, even though they are "equal", are not "the same", since they represent objects that live in different locations in memory.

> b === c
false

Jasmine's toBe matcher is nothing more than a wrapper for a strict equality comparison

expect(c.foo).toBe(b.foo)

is the same thing as

expect(c.foo === b.foo).toBe(true)

Don't just take my word for it; see the source code for toBe.

But b and c represent functionally equivalent objects; they both look like

{ foo: { bar: 'baz' } }

Wouldn't it be great if we could say that b and c are "equal" even if they don't represent the same object?

Enter toEqual, which checks "deep equality" (i.e. does a recursive search through the objects to determine whether the values for their keys are equivalent). Both of the following tests will pass:

expect(b).not.toBe(c);
expect(b).toEqual(c);

Hope that helps clarify some things.

Jason Scheirer's answer is correct but could use some more exposition.

First off, to repeat a string an integer number of times, you can use overloaded multiplication:

>>> 'abc' * 7
'abcabcabcabcabcabcabc'

So, to repeat a string until it's at least as long as the length you want, you calculate the appropriate number of repeats and put it on the right-hand side of that multiplication operator:

def repeat_to_at_least_length(s, wanted):
    return s * (wanted//len(s) + 1)

>>> repeat_to_at_least_length('abc', 7)
'abcabcabc'

Then, you can trim it to the exact length you want with an array slice:

def repeat_to_length(s, wanted):
    return (s * (wanted//len(s) + 1))[:wanted]

>>> repeat_to_length('abc', 7)
'abcabca'

Alternatively, as suggested in pillmod's answer that probably nobody scrolls down far enough to notice anymore, you can use divmod to compute the number of full repetitions needed, and the number of extra characters, all at once:

def pillmod_repeat_to_length(s, wanted):
    a, b = divmod(wanted, len(s))
    return s * a + s[:b]

Which is better? Let's benchmark it:

>>> import timeit
>>> timeit.repeat('scheirer_repeat_to_length("abcdefg", 129)', globals=globals())
[0.3964178159367293, 0.32557755894958973, 0.32851039397064596]
>>> timeit.repeat('pillmod_repeat_to_length("abcdefg", 129)', globals=globals())
[0.5276265419088304, 0.46511475392617285, 0.46291469305288047]

So, pillmod's version is something like 40% slower, which is too bad, since personally I think it's much more readable. There are several possible reasons for this, starting with its compiling to about 40% more bytecode instructions.

Note: these examples use the new-ish // operator for truncating integer division. This is often called a Python 3 feature, but according to PEP 238, it was introduced all the way back in Python 2.2. You only have to use it in Python 3 (or in modules that have from __future__ import division) but you can use it regardless.

I found joblib is very useful with me. Please see following example:

from joblib import Parallel, delayed
def yourfunction(k):   
    s=3.14*k*k
    print "Area of a circle with a radius ", k, " is:", s

element_run = Parallel(n_jobs=-1)(delayed(yourfunction)(k) for k in range(1,10))

n_jobs=-1: use all available cores

System.Text.Encoding.ChooseYourEncoding.GetString(bytes).ToCharArray();

Substitute the right encoding above: e.g.

System.Text.Encoding.UTF8.GetString(bytes).ToCharArray();

In case you are using zsh you can use for example the -E or -i switch:

history -E

If you do a man zshoptions or man zshbuiltins you can find out more information about these switches as well as other info related to history:

Also when listing,
 -d     prints timestamps for each event
 -f     prints full time-date stamps in the US `MM/DD/YY hh:mm' format
 -E     prints full time-date stamps in the European `dd.mm.yyyy hh:mm' format
 -i     prints full time-date stamps in ISO8601 `yyyy-mm-dd hh:mm' format
 -t fmt prints time and date stamps in the given format; fmt is formatted with the strftime function with the zsh extensions  described  for  the  %D{string} prompt format in the section EXPANSION OF PROMPT SEQUENCES in zshmisc(1).  The resulting formatted string must be no more than 256 characters or will not be printed
 -D     prints elapsed times; may be combined with one of the options above

You were almost there.

Remove protected $dates = ['license_expire']

and then change your LicenseExpire accessor to:

public function getLicenseExpireAttribute($date)
{
    return Carbon::parse($date);
}

This way it will return a Carbon instance no matter what. So for your form you would just have $employee->license_expire->format('Y-m-d') (or whatever format is required) and diffForHumans() should work on your home page as well.

Hope this helps!

Do you have a typo in your .h? I once came across this error when i had the method properly called in my main, but with a typo in the .h/.cpp (a "g" vs a "q" in the method name, which made it kinda difficult to spot). It falls under the "copy/paste error" category.

Did you try:

    execBtn.setAttribute("onclick", function() { runCommand() });

Upcasting and downcasting are important part of Java, which allow us to build complicated programs using simple syntax, and gives us great advantages, like Polymorphism or grouping different objects. Java permits an object of a subclass type to be treated as an object of any superclass type. This is called upcasting. Upcasting is done automatically, while downcasting must be manually done by the programmer, and i'm going to give my best to explain why is that so.

Upcasting and downcasting are NOT like casting primitives from one to other, and i believe that's what causes a lot of confusion, when programmer starts to learn casting objects.

Polymorphism: All methods in java are virtual by default. That means that any method can be overridden when used in inheritance, unless that method is declared as final or static.

You can see the example below how getType(); works according to the object(Dog,Pet,Police Dog) type.

Assume you have three dogs

1. Dog - This is the super Class.

2. Pet Dog - Pet Dog extends Dog.

3. Police Dog - Police Dog extends Pet Dog.

   public class Dog{ 
      public String getType () {
         System.out.println("NormalDog");
         return "NormalDog";
      }
    }
   
   /**
    * Pet Dog has an extra method dogName()
    */   
   public class PetDog extends Dog{ 
      public String getType () {
         System.out.println("PetDog");
         return "PetDog";
      }
      public String dogName () {
         System.out.println("I don't have Name !!");
         return "NO Name";
      }
    }
   
   /**
    * Police Dog has an extra method secretId()
    */
   public class PoliceDog extends PetDog{
   
    public String secretId() {
       System.out.println("ID");
       return "ID";
    }
   
    public String getType () {
        System.out.println("I am a Police Dog");
        return "Police Dog";
    }
   }
   

Polymorphism : All methods in java are virtual by default. That means that any method can be overridden when used in inheritance, unless that method is declared as final or static.(Explanation Belongs to Virtual Tables Concept)

Virtual Table / Dispatch Table : An object's dispatch table will contain the addresses of the object's dynamically bound methods. Method calls are performed by fetching the method's address from the object's dispatch table. The dispatch table is the same for all objects belonging to the same class, and is therefore typically shared between them.

public static void main (String[] args) {
      /**
       * Creating the different objects with super class Reference
       */
     Dog obj1 = new Dog();
`         /**
           *  Object of Pet Dog is created with Dog Reference since                
           *  Upcasting is done automatically for us we don't have to worry about it 
           *  
           */
     Dog obj2 = new PetDog();
`         /**
           *  Object of Police Dog is created with Dog Reference since                
           *  Upcasting is done automatically for us we don't have to worry       
           *  about it here even though we are extending PoliceDog with PetDog 
           *  since PetDog is extending Dog Java automatically upcast for us 
           */
      Dog obj3 = new PoliceDog();
}



 obj1.getType();

Prints Normal Dog

  obj2.getType();

Prints Pet Dog

 obj3.getType();

Prints Police Dog

Downcasting need to be done by the programmer manually

When you try to invoke the secretID(); method on obj3 which is PoliceDog object but referenced to Dog which is a super class in the hierarchy it throws error since obj3 don't have access to secretId() method.In order to invoke that method you need to Downcast that obj3 manually to PoliceDog

  ( (PoliceDog)obj3).secretID();

which prints ID

In the similar way to invoke the dogName();method in PetDog class you need to downcast obj2 to PetDog since obj2 is referenced to Dog and don't have access to dogName(); method

  ( (PetDog)obj2).dogName();

Why is that so, that upcasting is automatical, but downcasting must be manual? Well, you see, upcasting can never fail. But if you have a group of different Dogs and want to downcast them all to a to their types, then there's a chance, that some of these Dogs are actually of different types i.e., PetDog, PoliceDog, and process fails, by throwing ClassCastException.

This is the reason you need to downcast your objects manually if you have referenced your objects to the super class type.

Note: Here by referencing means you are not changing the memory address of your ojects when you downcast it it still remains same you are just grouping them to particular type in this case Dog

Boost has something to help: the Boost.Iterator library.

More precisely this page: boost::iterator_adaptor.

What's very interesting is the Tutorial Example which shows a complete implementation, from scratch, for a custom type.

template <class Value>
class node_iter
  : public boost::iterator_adaptor<
        node_iter<Value>                // Derived
      , Value*                          // Base
      , boost::use_default              // Value
      , boost::forward_traversal_tag    // CategoryOrTraversal
    >
{
 private:
    struct enabler {};  // a private type avoids misuse

 public:
    node_iter()
      : node_iter::iterator_adaptor_(0) {}

    explicit node_iter(Value* p)
      : node_iter::iterator_adaptor_(p) {}

    // iterator convertible to const_iterator, not vice-versa
    template <class OtherValue>
    node_iter(
        node_iter<OtherValue> const& other
      , typename boost::enable_if<
            boost::is_convertible<OtherValue*,Value*>
          , enabler
        >::type = enabler()
    )
      : node_iter::iterator_adaptor_(other.base()) {}

 private:
    friend class boost::iterator_core_access;
    void increment() { this->base_reference() = this->base()->next(); }
};

The main point, as has been cited already, is to use a single template implementation and typedef it.

A moving average can also be calculated and visualized directly in a line chart by using the following code:

Example using stock price data:

import pandas_datareader.data as web
import matplotlib.pyplot as plt
import datetime
plt.style.use('ggplot')

# Input variables
start = datetime.datetime(2016, 1, 01)
end = datetime.datetime(2018, 3, 29)
stock = 'WFC'

# Extrating data
df = web.DataReader(stock,'morningstar', start, end)
df = df['Close']

print df 

plt.plot(df['WFC'],label= 'Close')
plt.plot(df['WFC'].rolling(9).mean(),label= 'MA 9 days')
plt.plot(df['WFC'].rolling(21).mean(),label= 'MA 21 days')
plt.legend(loc='best')
plt.title('Wells Fargo\nClose and Moving Averages')
plt.show()

Tutorial on how to do this: https://youtu.be/XWAPpyF62Vg

Would you be happy with your Python command running another program to get the info?

If so, I'd suggest you have a look at PsList and all its options. For example, The following would tell you about any running iTunes process

PsList itunes

If you can work out how to interpret the results, this should hopefully get you going.

Edit:

When I'm not running iTunes, I get the following:

pslist v1.29 - Sysinternals PsList
Copyright (C) 2000-2009 Mark Russinovich
Sysinternals

Process information for CLARESPC:

Name                Pid Pri Thd  Hnd   Priv        CPU Time    Elapsed Time
iTunesHelper       3784   8  10  229   3164     0:00:00.046     3:41:05.053

With itunes running, I get this one extra line:

iTunes              928   8  24  813 106168     0:00:08.734     0:02:08.672

However, the following command prints out info only about the iTunes program itself, i.e. with the -e argument:

pslist -e itunes

The following query is very helpful

select  * from
(select count(*) used from pg_stat_activity) q1,
(select setting::int res_for_super from pg_settings where name=$$superuser_reserved_connections$$) q2,
(select setting::int max_conn from pg_settings where name=$$max_connections$$) q3;

If you pasted your text into the path variable and added a whitespace before the semicolon, you should delete that and add a backslash at the end of the directory (;C:\Program Files (x86)\CodeBlocks\MinGW\bin

In my case I was trying to convert my project into Maven. After while(and thousands of random errors which were saying NOTHING) I tried to undo all of operations. What I didn't notice .project file was changed and it wasn't visible inside Eclipse.

Only reverting .project file to before-maven version helped me fixing this error.

You can use the option -C (or --directory if you prefer long options) to give the target directory of your choice in case you are using the Gnu version of tar. The directory should exist:

mkdir foo
tar -xzf bar.tar.gz -C foo

If you are not using a tar capable of extracting to a specific directory, you can simply cd into your target directory prior to calling tar; then you will have to give a complete path to your archive, of course. You can do this in a scoping subshell to avoid influencing the surrounding script:

mkdir foo
(cd foo; tar -xzf ../bar.tar.gz)  # instead of ../ you can use an absolute path as well

Or, if neither an absolute path nor a relative path to the archive file is suitable, you also can use this to name the archive outside of the scoping subshell:

TARGET_PATH=a/very/complex/path/which/might/even/be/absolute
mkdir -p "$TARGET_PATH"
(cd "$TARGET_PATH"; tar -xzf -) < bar.tar.gz

import sys
sys.exit()

new Date().toISOString().slice(0, 10)+" "+new Date().toLocaleTimeString('en-GB');

The directory 'node_modules' may not be in current directory, so you should resolve the path dynamically.

var bootstrap_dir = require.resolve('bootstrap')
                           .match(/.*\/node_modules\/[^/]+\//)[0];
app.use('/scripts', express.static(bootstrap_dir + 'dist/'));

Compare date only instead of date + time (NOW) with:

CURDATE()

this should work, haven't tried though. this will exclude zero. NULL is excluded by default

AVG (CASE WHEN SecurityW <> 0 THEN SecurityW ELSE NULL END)

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

This is my method, you can define and input and output format.

public static String formattedDateFromString(String inputFormat, String outputFormat, String inputDate){
    if(inputFormat.equals("")){ // if inputFormat = "", set a default input format.
        inputFormat = "yyyy-MM-dd hh:mm:ss";
    }
    if(outputFormat.equals("")){
        outputFormat = "EEEE d 'de' MMMM 'del' yyyy"; // if inputFormat = "", set a default output format.
    }
    Date parsed = null;
    String outputDate = "";

    SimpleDateFormat df_input = new SimpleDateFormat(inputFormat, java.util.Locale.getDefault());
    SimpleDateFormat df_output = new SimpleDateFormat(outputFormat, java.util.Locale.getDefault());

    // You can set a different Locale, This example set a locale of Country Mexico.
    //SimpleDateFormat df_input = new SimpleDateFormat(inputFormat, new Locale("es", "MX"));
    //SimpleDateFormat df_output = new SimpleDateFormat(outputFormat, new Locale("es", "MX"));

    try {
        parsed = df_input.parse(inputDate);
        outputDate = df_output.format(parsed);
    } catch (Exception e) { 
        Log.e("formattedDateFromString", "Exception in formateDateFromstring(): " + e.getMessage());
    }
    return outputDate;

}

You can just use wildcards in the predicate (after IF, WHERE or ON):

@mainstring LIKE '%' + @substring + '%'

or in this specific case

' ' + @mainstring + ' ' LIKE '% ME[., ]%'

(Put the spaces in the quoted string if you're looking for the whole word, or leave them out if ME can be part of a bigger word).

MultipleIE , IETester there are many similar to those.

Multiple IE supports IE3 IE4.01 IE5 IE5.5 and IE6 and "is no longer maintained and there are no plans to continue maintaining it! Thanks and good luck!".

IETester seems a better choice : IE10, IE9, IE8, IE7 IE 6 and IE5.5 on Windows 8 desktop, Windows 7, Vista and XP

Line width in ggplot2 can be changed with argument size= in geom_line().

#sample data
df<-data.frame(x=rnorm(100),y=rnorm(100))
ggplot(df,aes(x=x,y=y))+geom_line(size=2)

I took Jezzipin's answer and made it so that if you are scrolled when you refresh the page, the correct size applies. Also removed some stuff that isn't necessarily needed.

function sizer() {
    if($(document).scrollTop() > 0) {
        $('#header_nav').stop().animate({
            height:'40px'
        },600);
    } else {
        $('#header_nav').stop().animate({
            height:'100px'
        },600);
    }
}

$(window).scroll(function(){
    sizer();
});

sizer();

This is another C example of where the same syntax has different meanings (in different places). While one might be able to argue that the syntax should be different for these two cases, it is what it is. The idea is that not that it is "not allowed" but that the second thing means something different (it means "pointer assignment").

Here's a quick and easy method:

CREATE TABLE database1.employees
AS
SELECT * FROM database2.employees;

Assuming you have Xcode installed in /Applications, then you can do this from the command line to start the iPhone Simulator:

$ open /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app

(Xcode 6+):

$ open /Applications/Xcode.app/Contents/Developer/Applications/iOS Simulator.app

You could create a symbolic-link from your Desktop to make this easier:

$ ln -s /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app ~/Desktop

(Xcode 6+):

$ ln -s /Applications/Xcode.app/Contents/Developer/Applications/iOS Simulator.app ~/Desktop

As pointed out by @JackHahoney, you could also add an alias to your ~/.bash_profile:

$ alias simulator='open /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/De??veloper/Applications/iPhone\ Simulator.app'

(Xcode 6+):

$ alias simulator='open /Applications/Xcode.app/Contents/Developer/Applications/iOS\ Simulator.app'

(Xcode 7+):

$ alias simulator='open /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app'

Which would mean you could start the iPhone Simulator from the command line with one easy-to-remember word:

$ simulator

Try xdebug extension for php.

Example:

<?php var_dump($_SERVER); ?>

Outputs:

Even though @Rick has the accepted answer for this question, there's actually a shorter way to do this, using the poorly named Uri.GetLeftPart() method.

Uri url = new Uri("http://www.mywebsite.com:80/pages/page1.aspx");
string output = url.GetLeftPart(UriPartial.Authority);

There is one catch to GetLeftPart(), however. If the port is the default port for the scheme, it will strip it out. Since port 80 is the default port for http, the output of GetLeftPart() in my example above will be http://www.mywebsite.com.

If the port number had been something other than 80, it would be included in the result.

I run across this and at the beginning I found it really confusing to be honest and I think this confusion comes from using the word "CMD" because in fact what goes there acts as argument. So after digging a little bit I understood how it works. Basically:

ENTRYPOINT --> what you specify here would be the command to be executed when you container starts. If you omit this definition docker will use /bin/sh -c bash to run your container.

CMD --> these are the arguments appended to the ENTRYPOINT unless the user specifies some custom argument, i.e: docker run ubuntu <custom_cmd> in this case instead of appending what's specified on the image in the CMD section, docker will run ENTRYPOINT <custom_cmd>. In case ENTRYPOINT has not been specified, what goes here will be passed to /bin/sh -c acting in fact as the command to be executed when starting the container.

As everything it's better to explain what's going on by examples. So let's say I create a simple docker image by using the following specification Dockerfile:

From ubuntu
ENTRYPOINT ["sleep"]

Then I build it by running the following:

docker build . -t testimg

This will create a container that everytime you run it sleeps. So If I run it as following:

docker run testimg

I'll get the following:

sleep: missing operand
Try 'sleep --help' for more information.

This happens because the entry point is the "sleep" command which needs an argument. So to fix this I'll just provide the amount to sleep:

docker run testimg 5

This will run correctly and as consequence the container will run, sleeps 5 seconds and exits. As we can see in this example docker just appended what goes after the image name to the entry point binary docker run testimg <my_cmd>. What happens if we want to pass a default value (default argument) to the entry point? in this case we just need to specify it in the CMD section, for example:

From ubuntu
ENTRYPOINT ["sleep"]
CMD ["10"]

In this case if the user doesn't pass any argument the container will use the default value (10) and pass it to entry point sleep.

Now let's use just CMD and omit ENTRYPOINT definition:

FROM ubuntu
CMD ["sleep", "5"]

If we rebuild and run this image it will basically sleeps for 5 seconds.

So in summary, you can use ENTRYPOINT in order to make your container acts as an executable. You can use CMD to provide default arguments to your entry point or to run a custom command when starting your container that can be overridden from outside by user.

I ran into the same error.

NAME         READY   STATUS             RESTARTS   AGE
pod/webapp   0/1     CrashLoopBackOff   5          47h

My problem was that I was trying to run two different pods with the same metadata name.

kind: Pod metadata: name: webapp labels: ...

To find all the names of your pods run: kubectl get pods

NAME         READY   STATUS    RESTARTS   AGE
webapp       1/1     Running   15         47h

then I changed the conflicting pod name and everything worked just fine.

NAME                 READY   STATUS    RESTARTS   AGE
webapp               1/1     Running   17         2d

I think it is dangerous to use $.isEmptyObject from jquery to check whether the array is empty, as @jesenko mentioned. I just met that problem.

In the isEmptyObject doc, it mentions:

The argument should always be a plain JavaScript Object

which you can determine by $.isPlainObject. The return of $.isPlainObject([]) is false.

Is there any equivalent for the truststore? How can I view the trusted certificates?

Yes there is.The exact same command since keystore and truststore differ only in what they store i.e. private key or signed public key (certificate)

No other difference

If you are not using any javascript/jquery for form validation, then a simple layout for your form would look like this.

within the body of your html document:

<form action="formHandler.php" name="yourForm" id="theForm" method="post">    
    <input type="text" name="fname" id="fname" />    
    <input type="submit" value="submit"/>
</form>

You need to ensure you have the submit button within the form tags, and an appropriate action assigned. Such as sending to a php file.

For a more direct answer, provide the code you are working with.

You may find the following of use: http://www.w3.org/TR/html401/interact/forms.html

Add the following code before you instantiate your web service client:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Or for backward compatibility with TLS 1.1 and prior:

System.Net.ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12; 

Type the following in the linux/ubuntu terminal

 crontab -e 

select an editor (sometime it asks for the editor) and this to run for every minute

*       *       *       *       *       /usr/bin/php path/to/cron.php &> /dev/null

I always use 0. Not for any real thought out reason, just because when I was first learning C++ I read something that recommended using 0 and I've just always done it that way. In theory there could be a confusion issue in readability but in practice I have never once come across such an issue in thousands of man-hours and millions of lines of code. As Stroustrup says, it's really just a personal aesthetic issue until the standard becomes nullptr.

It worth mentioning that if you intend to package your application with PyInstaller and wise to avoid supporting that feature by yourself, you can pass the --uac-admin or --uac-uiaccess argument in order to request UAC elevation on start.

If you are using hand inputted data, you can enter your data as mm:ss,0 or mm:ss.0 depending on your language/region selection instead of 00:mm:ss.

You need to specify your cell format as [m]:ss if you like to see all minutes seconds format instead of hours minutes seconds format.

I was having the same issue with font awesome 5 downloaded with yarn, I made added the min.css file ALONG with the all.js file.

Hope this helps someone someone

Change your return type to java.lang.Integer . This way you can safely return null

If you don't want to store your password in plaintext like Mark said, you can use a different GitHub URL for fetching than you do for pushing. In your configuration file, under [remote "origin"]:

url = git://github.com/you/projectName.git
pushurl = [email protected]:you/projectName.git

It will still ask for a password when you push, but not when you fetch, at least for open source projects.

May use this-

#if defined CONDITION1 || defined CONDITION2
//your code here
#endif

This also does the same-

#if defined(CONDITION1) || defined(CONDITION2)
//your code here
#endif

Further-

• AND: #if defined CONDITION1 && defined CONDITION2
• XOR: #if defined CONDITION1 ^ defined CONDITION2
• AND NOT: #if defined CONDITION1 && !defined CONDITION2

You can get the total count of lines with wc -l <file> and use

head -n <total lines - lines to remove> <file>

It's not a cut and paste. The CASE expression must return a value, and you are returning a string containing SQL (which is technically a value but of a wrong type). This is what you wanted to write, I think:

SELECT * FROM [Purchasing].[Vendor] WHERE  
CASE
  WHEN @url IS null OR @url = '' OR @url = 'ALL'
    THEN PurchasingWebServiceURL LIKE '%'
  WHEN @url = 'blank'
    THEN PurchasingWebServiceURL = ''
  WHEN @url = 'fail'
    THEN PurchasingWebServiceURL NOT LIKE '%treyresearch%'
  ELSE PurchasingWebServiceURL = '%' + @url + '%' 
END

I also suspect that this might not work in some dialects, but can't test now (Oracle, I'm looking at you), due to not having booleans.

However, since @url is not dependent on the table values, why not make three different queries, and choose which to evaluate based on your parameter?

the position:fixed; property should do the work, I used it on my Website and it worked fine. http://www.w3schools.com/css/css_positioning.asp

Try this configuration:

    position to absolute
    width to 100%
    height to 100px
    bottom to 10
    background-color: blue

This can help actually move the div to the bottom. Just modify accordingly.

You can print the PHP variable into your javascript while your page is created.

<script type="text/javascript">
    var MyJSStringVar = "<?php Print($MyPHPStringVar); ?>";
    var MyJSNumVar = <?php Print($MyPHPNumVar); ?>;
</script>

Of course this is for simple variables and not objects.

your excel file's extension change to xml. And open it in notepad. password text find in xml file.

I faced the same issue, I deleted all provisioning assets from xcode & added them back, and just relaunched Xcode.

My App was loaded on to the device and it worked.

DickFeynman's answer is a workable solution for any circumstance in which JQuery is not a good fit, or isn't otherwise necessary. As ComFreek notes, this requires setting the CORS headers on the server-side. If it's your service, and you have a handle on the bigger question of security, then that's entirely feasible.

Here's a listing of a Flask service, setting the CORS headers, grabbing data from a database, responding with JSON, and working happily with DickFeynman's approach on the client-side:

#!/usr/bin/env python 
from __future__ import unicode_literals
from flask      import Flask, Response, jsonify, redirect, request, url_for
from your_model import *
import os
try:
    import simplejson as json;
except ImportError:
    import json
try:
    from flask.ext.cors import *
except:
    from flask_cors import *

app = Flask(__name__)

@app.before_request
def before_request():
try:
    # Provided by an object in your_model
    app.session = SessionManager.connect()
except:
    print "Database connection failed."

@app.teardown_request
def shutdown_session(exception=None):
    app.session.close()

# A route with a CORS header, to enable your javascript client to access 
# JSON created from a database query.
@app.route('/whatever-data/', methods=['GET', 'OPTIONS'])
@cross_origin(headers=['Content-Type'])
def json_data():
    whatever_list = []
    results_json  = None
    try:
        # Use SQL Alchemy to select all Whatevers, WHERE size > 0.
        whatevers = app.session.query(Whatever).filter(Whatever.size > 0).all()
        if whatevers and len(whatevers) > 0:
            for whatever in whatevers:
                # Each whatever is able to return a serialized version of itself. 
                # Refer to your_model.
                whatever_list.append(whatever.serialize())
             # Convert a list to JSON. 
             results_json = json.dumps(whatever_list)
    except SQLAlchemyError as e:
        print 'Error {0}'.format(e)
        exit(0)

    if len(whatevers) < 1 or not results_json:
        exit(0)
    else:
        # Because we used json.dumps(), rather than jsonify(), 
        # we need to create a Flask Response object, here.
        return Response(response=str(results_json), mimetype='application/json')

if __name__ == '__main__':
    #@NOTE Not suitable for production. As configured, 
    #      your Flask service is in debug mode and publicly accessible.  
    app.run(debug=True, host='0.0.0.0', port=5001) # http://localhost:5001/

your_model contains the serialization method for your whatever, as well as the database connection manager (which could stand a little refactoring, but suffices to centralize the creation of database sessions, in bigger systems or Model/View/Control architectures). This happens to use postgreSQL, but could just as easily use any server side data store:

      return Base

Base = SessionManager.declareBase()

        self.whatever_raw            = whatever_raw
        self.whatever_label          = whatever_label

    # Serialize one way or another, just handle appropriately in the client.  
    def serialize(self):
        return {
            'best_name'     :self.best_name,
            'whatever_label':self.whatever_label,
            'size'          :self.size,
        }

In retrospect, I might have serialized the whatever objects as lists, rather than a Python dict, which might have simplified their processing in the Flask service, and I might have separated concerns better in the Flask implementation (The database call probably shouldn't be built-in the the route handler), but you can improve on this, once you have a working solution in your own development environment.

Also, I'm not suggesting people avoid JQuery. But, if JQuery's not in the picture, for one reason or another, this approach seems like a reasonable alternative.

It works, in any case.

Here's my implementation of DickFeynman's approach, in the the client:

<script type="text/javascript">
    var addr = "dev.yourserver.yourorg.tld"
    var port = "5001"

    function Get(whateverUrl){
        var Httpreq = new XMLHttpRequest(); // a new request
        Httpreq.open("GET",whateverUrl,false);
        Httpreq.send(null);
        return Httpreq.responseText;          
    }

    var whatever_list_obj = JSON.parse(Get("http://" + addr + ":" + port + "/whatever-data/"));
    whatever_qty = whatever_list_obj.length;
    for (var i = 0; i < whatever_qty; i++) {
        console.log(whatever_list_obj[i].best_name);
    }
</script>

I'm not going to list my console output, but I'm looking at a long list of whatever.best_name strings.

More to the point: The whatever_list_obj is available for use in my javascript namespace, for whatever I care to do with it, ...which might include generating graphics with D3.js, mapping with OpenLayers or CesiumJS, or calculating some intermediate values which have no particular need to live in my DOM.

it appears that there is no ready to use java api that makes that but you can write a method to do that for you. this link might be usefull

Unlike div, p ¹ which are Block Level elements which can take up margin on all sides,span² cannot as it's an Inline element which takes up margins horizontally only.

From the specification:

Margin properties specify the width of the margin area of a box. The 'margin' shorthand property sets the margin for all four sides while the other margin properties only set their respective side. These properties apply to all elements, but vertical margins will not have any effect on non-replaced inline elements.

Demo 1 (Vertical margin not applied as span is an inline element)

Solution? Make your span element, display: inline-block; or display: block;.

Demo 2

Would suggest you to use display: inline-block; as it will be inline as well as block. Making it block only will result in your element to render on another line, as block level elements take 100% of horizontal space on the page, unless they are made inline-block or they are floated to left or right.

^{1. Block Level Elements - MDN Source}

^{2. Inline Elements - MDN Resource}

The first is the original for loop. You initialize a variable, set a terminating condition, and provide a state incrementing/decrementing counter (There are exceptions, but this is the classic)

For that,

for (int i=0;i<myString.length;i++) { 
  System.out.println(myString[i]); 
}

is correct.

For Java 5 an alternative was proposed. Any thing that implements iterable can be supported. This is particularly nice in Collections. For example you can iterate the list like this

List<String> list = ....load up with stuff

for (String string : list) {
  System.out.println(string);
}

instead of

for (int i=0; i<list.size();i++) {
  System.out.println(list.get(i));
}

So it's just an alternative notation really. Any item that implements Iterable (i.e. can return an iterator) can be written that way.

What's happening behind the scenes is somethig like this: (more efficient, but I'm writing it explicitly)

Iterator<String> it = list.iterator();
while (it.hasNext()) {
  String string=it.next();
  System.out.println(string);
}

In the end it's just syntactic sugar, but rather convenient.

Here's my solution:

toolbar.navigationIcon?.mutate()?.let {
  it.setTint(theColor)
  toolbar.navigationIcon = it
}

Or, if you want to use a nice function for it:

fun Toolbar.setNavigationIconColor(@ColorInt color: Int) = navigationIcon?.mutate()?.let {
    it.setTint(color)
    this.navigationIcon = it
}

Usage:

toolbar.setNavitationIconColor(someColor)

More easy to understand (What is Lambda actually doing):

ls2=[[0,1,'f'],[4,2,'t'],[9,4,'afsd']]
def thirdItem(ls):
    #return the third item of the list
    return ls[2]
#Sort according to what the thirdItem function return 
ls2.sort(key=thirdItem)

Your string is not valid. Double quots cannot be inside double quotes. You should escape them:

"{\"TeamList\" : [{\"teamid\" : \"1\",\"teamname\" : \"Barcelona\"}]}"

or use single quotes and double quotes

'{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}'

Expanding upon Gustavo Lima's answer. The same thing can be done without creating an entirely new list. The values in the list can be replaced with the differentials as the FOR loop progresses.

def f_ClosestVal(v_List, v_Number):
"""Takes an unsorted LIST of INTs and RETURNS INDEX of value closest to an INT"""
for _index, i in enumerate(v_List):
    v_List[_index] = abs(v_Number - i)
return v_List.index(min(v_List))

myList = [1, 88, 44, 4, 4, -2, 3]
v_Num = 5
print(f_ClosestVal(myList, v_Num)) ## Gives "3," the index of the first "4" in the list.

Also can use without parent

say router definition like:

{path:'/about',    name: 'About',   component: AboutComponent}

then can navigate by name instead of path

goToAboutPage() {
    this.router.navigate(['About']); // here "About" is name not path
}

Updated for V2.3.0

In Routing from v2.0 name property no more exist. route define without name property. so you should use path instead of name. this.router.navigate(['/path']) and no leading slash for path so use path: 'about' instead of path: '/about'

router definition like:

{path:'about', component: AboutComponent}

then can navigate by path

goToAboutPage() {
    this.router.navigate(['/about']); // here "About" is path
}

The situation with regexes, Unicode, and Javascript sucks. It's ridiculous that programmers should have to rely on external libraries to recognize that "??fa" is a word, or even that "é" is a letter.

But so it goes.

This guy has written a good library for handling Unicode in Javascript Regexes:

http://blog.stevenlevithan.com/archives/javascript-regex-and-unicode

The Unicode stuff is a plugin to this regex library:

http://xregexp.com/

Here's a post about the Unicode extension:

http://blog.stevenlevithan.com/archives/xregexp-unicode-plugin

And the extension page itself:

http://xregexp.com/plugins/

Great work but it still bums me out that Javascript is so backwards in this regard.

(He wrote a book for O'Reilly about the topic so it's quite possible that he knows what he's talking about.)

The way he implemented it is by adding tables of characters with certain properties. Then, when you contruct a regex with his library, \p{charclass} gets replaced with [allthecharactersintheclass].

The easy way to revert a group of commits on shared repository (that people use and you want to preserve the history) is to use git revert in conjunction with git rev-list. The latter one will provide you with a list of commits, the former will do the revert itself.

There are two ways to do that. If you want the revert multiple commits in a single commit use:

for i in `git rev-list <first-commit-sha>^..<last-commit-sha>`; do git revert --no-commit $i; done

this will revert a group of commits you need, but leave all the changes on your working tree, you should commit them all as usual afterward.

Another option is to have a single commit per reverted change:

for i in `git rev-list <first-commit-sha>^..<last-commit-sha>`; do git revert --no-edit -s $i; done

For instance, if you have a commit tree like

 o---o---o---o---o---o--->    
fff eee ddd ccc bbb aaa

to revert the changes from eee to bbb, run

for i in `git rev-list eee^..bbb`; do git revert --no-edit -s $i; done

You could query the sys.tables database view to get out the names of the tables, and then use this query to build yourself another query to do the update on the back of that. For instance:

select 'select * from '+name from sys.tables

will give you a script that will run a select * against all the tables in the system catalog, you could alter the string in the select clause to do your update, as long as you know the column name is the same on all the tables you wish to update, so your script would look something like:

select 'update '+name+' set comments = ''(*)''+comments where comments like ''%comment to be updated%'' ' from sys.tables

You could also then predicate on the tables query to only include tables that have a name in a certain format, or are in a subset you want to create the update script for.

You can also use the following syntax:-

INSERT INTO MyTable (FirstCol, SecondCol)
SELECT 'First' ,1
UNION ALL
SELECT 'Second' ,2
UNION ALL
SELECT 'Third' ,3
UNION ALL
SELECT 'Fourth' ,4
UNION ALL
SELECT 'Fifth' ,5
GO

From here

You can run build for a specific service by running docker-compose up --build <service name> where the service name must match how did you call it in your docker-compose file.

Example Let's assume that your docker-compose file contains many services (.net app - database - let's encrypt... etc) and you want to update only the .net app which named as application in docker-compose file. You can then simply run docker-compose up --build application

Extra parameters In case you want to add extra parameters to your command such as -d for running in the background, the parameter must be before the service name: docker-compose up --build -d application

attr("dominant-baseline", "central")

I had the same error. Here was my workflow. I first installed PIL (not Pillow) using

pip install --no-index -f https://dist.plone.org/thirdparty/ -U PIL

Then I found Pillow and installed it using

pip install Pillow

What fixed my issues was uninstalling both and reinstalling Pillow

pip uninstall PIL
pip uninstall Pillow
pip install Pillow

I had the same problem. Was using bitbucket and had trouble in pulling/updating the repository on Intellij. Tried changing to native and back to built in, but it was not working. Then realized that I had generated the ssh key with a passphrase.

I regenerated the key without the passphrase and then added it to the bitbucket. It worked !

If you are using gradle just update ypur gradle plugin!

Change line in build.gradle from:

classpath 'com.android.tools.build:gradle:0.9.+'

to:

classpath 'com.android.tools.build:gradle:0.11.+'

It works for me.

Note that variable buildToolsVersion (for me "20.0.0") must match your version of build-tools.

Good luck :)

To add spacing between entries in a legend, adjust the margins of the theme element legend.text.

To add 30pt of space to the right of each legend label (may be useful for a horizontal legend):

p + theme(legend.text = element_text(
    margin = margin(r = 30, unit = "pt")))

To add 30pt of space to the left of each legend label (may be useful for a vertical legend):

p + theme(legend.text = element_text(
    margin = margin(l = 30, unit = "pt")))

for a ggplot2 object p. The keywords are legend.text and margin.

[Note about edit: When this answer was first posted, there was a bug. The bug has now been fixed]

The possible reason can also be that you have not inherited Controller from ApiController. Happened with me took a while to understand the same.

-- This gives you the time as 0 in format 'yyyy-mm-dd 00:00:00.000'

SELECT CAST( CONVERT(VARCHAR, GETDATE(), 101) AS DATETIME) ; 

Simply declare length to be a cons, if it is not then you should be allocating memory dynamically

From further research, I've found:

Security Fix:

An SQL-injection security hole has been found in multi-byte encoding processing. The bug was in the server, incorrectly parsing the string escaped with the mysql_real_escape_string() C API function.

This vulnerability was discovered and reported by Josh Berkus and Tom Lane as part of the inter-project security collaboration of the OSDB consortium. For more information about SQL injection, please see the following text.

Discussion. An SQL injection security hole has been found in multi-byte encoding processing. An SQL injection security hole can include a situation whereby when a user supplied data to be inserted into a database, the user might inject SQL statements into the data that the server will execute. With regards to this vulnerability, when character set-unaware escaping is used (for example, addslashes() in PHP), it is possible to bypass the escaping in some multi-byte character sets (for example, SJIS, BIG5 and GBK). As a result, a function such as addslashes() is not able to prevent SQL-injection attacks. It is impossible to fix this on the server side. The best solution is for applications to use character set-aware escaping offered by a function such mysql_real_escape_string().

However, a bug was detected in how the MySQL server parses the output of mysql_real_escape_string(). As a result, even when the character set-aware function mysql_real_escape_string() was used, SQL injection was possible. This bug has been fixed.

Workarounds. If you are unable to upgrade MySQL to a version that includes the fix for the bug in mysql_real_escape_string() parsing, but run MySQL 5.0.1 or higher, you can use the NO_BACKSLASH_ESCAPES SQL mode as a workaround. (This mode was introduced in MySQL 5.0.1.) NO_BACKSLASH_ESCAPES enables an SQL standard compatibility mode, where backslash is not considered a special character. The result will be that queries will fail.

To set this mode for the current connection, enter the following SQL statement:

SET sql_mode='NO_BACKSLASH_ESCAPES';

You can also set the mode globally for all clients:

SET GLOBAL sql_mode='NO_BACKSLASH_ESCAPES';

This SQL mode also can be enabled automatically when the server starts by using the command-line option --sql-mode=NO_BACKSLASH_ESCAPES or by setting sql-mode=NO_BACKSLASH_ESCAPES in the server option file (for example, my.cnf or my.ini, depending on your system). (Bug#8378, CVE-2006-2753)

Yes, use the rendered attribute.

<h:form rendered="#{some boolean condition}">

You usually tie it to the model rather than letting the model grab the component and manipulate it.

E.g.

<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

Note the importance of keyword based EL operators such as gt, ge, le and lt instead of >, >=, <= and < as angle brackets < and > are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.

As to your specific use case, let's assume that the link is passing a parameter like below:

<a href="page.xhtml?form=1">link</a>

You can then show the form as below:

<h:form rendered="#{param.form eq '1'}">

(the #{param} is an implicit EL object referring to a Map representing the request parameters)

Try:

exec('drop table #tab') -- you can add condition 'if table exists'
exec('select * into #tab from tab')

You can use jQuery each function as it is explained below:

Define your data:

var jsonStr = '[{"name":"Lenovo Thinkpad 41A4298,"website":"google"},{"name":"Lenovo Thinkpad 41A2222,"website":"google"},{"name":"Lenovo Thinkpad 41Awww33,"website":"yahoo"},{"name":"Lenovo Thinkpad 41A424448,"website":"google"},{"name":"Lenovo Thinkpad 41A429rr8,"website":"ebay"},{"name":"Lenovo Thinkpad 41A429ff8,"website":"ebay"},{"name":"Lenovo Thinkpad 41A429ss8,"website":"rediff"},{"name":"Lenovo Thinkpad 41A429sg8,"website":"yahoo"}]';

Parse JSON string to JSON object:

var json = JSON.parse(jsonStr);

Iterate and filter:

$.each(JSON.parse(json), function (idx, obj) {
    if (obj.website == 'yahoo') {
        // do whatever you want
    }
});

To update and answer the question without breaking mail servers. Later versions of CentOS 7 have MariaDB included as the base along with PostFix which relies on MariaDB. Removing using yum will also remove postfix and perl-DBD-MySQL. To get around this and keep postfix in place, first make a copy of /usr/lib64/libmysqlclient.so.18 (which is what postfix depends on) and then use:

rpm -qa | grep mariadb

then remove the mariadb packages using (changing to your versions):

rpm -e --nodeps "mariadb-libs-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-server-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-5.5.56-2.el7.x86_64"

Delete left over files and folders (which also removes any databases):

rm -f /var/log/mariadb
rm -f /var/log/mariadb/mariadb.log.rpmsave
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
rm -rf /usr/share/mysql

Put back the copy of /usr/lib64/libmysqlclient.so.18 you made at the start and you can restart postfix.

There is more detail at https://code.trev.id.au/centos-7-remove-mariadb-replace-mysql/ which describes how to replace mariaDB with MySQL

I would handle it like so:

$(document).ready(function() {
   $('input[type="radio"]').click(function() {
       if($(this).attr('id') == 'watch-me') {
            $('#show-me').show();           
       }

       else {
            $('#show-me').hide();   
       }
   });
});

>>> names = ['King', 'Queen', 'Joker']
>>> any(n in 'King and john' for n in names)
True

>>> all(n in 'King and Queen' for n in names)
False

It just reduce several line of code into one. You don't have to write lengthy code like:

for n in names:
    if n in 'King and john':
       print True
    else:
       print False

sudo su root

chown -R user:group dir

The dir is your git repo.

Then do:

git pull origin master

You'll see changes about commits by others.

It's likely that your output encoding is set to ASCII. Try using this before sending output:

Console.OutputEncoding = System.Text.Encoding.UTF8;

(MSDN link to supporting documentation.)

And here's a little console test app you may find handy:

C#

using System;
using System.Text;

public static class ConsoleOutputTest {
    public static void Main() {
        Console.OutputEncoding = System.Text.Encoding.UTF8;
        for (var i = 0; i <= 1000; i++) {
            Console.Write(Strings.ChrW(i));
            if (i % 50 == 0) { // break every 50 chars
                Console.WriteLine();
            }
        }
        Console.ReadKey();
    }
}

VB.NET

imports Microsoft.VisualBasic
imports System

public module ConsoleOutputTest 
    Sub Main()
        Console.OutputEncoding = System.Text.Encoding.UTF8
        dim i as integer
        for i = 0 to 1000
            Console.Write(ChrW(i))
            if i mod 50 = 0 'break every 50 chars 
                Console.WriteLine()
            end if
        next
    Console.ReadKey()
    End Sub
end module

It's also possible that your choice of Console font does not support that particular character. Click on the Windows Tool-bar Menu (icon like C:.) and select Properties -> Font. Try some other fonts to see if they display your character properly:

Every Ansible task when run can save its results into a variable. To do this, you have to specify which variable to save the results into. Do this with the register parameter, independently of the module used.

Once you save the results to a variable you can use it later in any of the subsequent tasks. So for example if you want to get the standard output of a specific task you can write the following:

---
- hosts: localhost
  tasks:
    - shell: ls
      register: shell_result

    - debug:
        var: shell_result.stdout_lines

Here register tells ansible to save the response of the module into the shell_result variable, and then we use the debug module to print the variable out.

An example run would look like the this:

PLAY [localhost] ***************************************************************

TASK [command] *****************************************************************
changed: [localhost]

TASK [debug] *******************************************************************
ok: [localhost] => {
    "shell_result.stdout_lines": [
        "play.yml"
    ]
}

Responses can contain multiple fields. stdout_lines is one of the default fields you can expect from a module's response.

Not all fields are available from all modules, for example for a module which doesn't return anything to the standard out you wouldn't expect anything in the stdout or stdout_lines values, however the msg field might be filled in this case. Also there are some modules where you might find something in a non-standard variable, for these you can try to consult the module's documentation for these non-standard return values.

Alternatively you can increase the verbosity level of ansible-playbook. You can choose between different verbosity levels: -v, -vvv and -vvvv. For example when running the playbook with verbosity (-vvv) you get this:

PLAY [localhost] ***************************************************************

TASK [command] *****************************************************************
(...)
changed: [localhost] => {
    "changed": true,
    "cmd": "ls",
    "delta": "0:00:00.007621",
    "end": "2017-02-17 23:04:41.912570",
    "invocation": {
        "module_args": {
            "_raw_params": "ls",
            "_uses_shell": true,
            "chdir": null,
            "creates": null,
            "executable": null,
            "removes": null,
            "warn": true
        },
        "module_name": "command"
    },
    "rc": 0,
    "start": "2017-02-17 23:04:41.904949",
    "stderr": "",
    "stdout": "play.retry\nplay.yml",
    "stdout_lines": [
        "play.retry",
        "play.yml"
    ],
    "warnings": []
}

As you can see this will print out the response of each of the modules, and all of the fields available. You can see that the stdout_lines is available, and its contents are what we expect.

To answer your main question about the jenkins_script module, if you check its documentation, you can see that it returns the output in the output field, so you might want to try the following:

tasks:
  - jenkins_script:
      script: (...)
    register: jenkins_result

  - debug:
      var: jenkins_result.output

A BufferedReader constructor takes a reader as argument, not an InputStream. You should first create a Reader from your stream, like so:

Reader reader = new InputStreamReader(is);
BufferedReader br = new BufferedReader(reader);

Preferrably, you also provide a Charset or character encoding name to the StreamReader constructor. Since a stream just provides bytes, converting these to text means the encoding must be known. If you don't specify it, the system default is assumed.

rake routes | grep <specific resource name>

displays resource specific routes, if it is a pretty long list of routes.

The expression *src refers to the first character in the string, not the whole string. To reassign src to point to a different string tgt, use src = tgt;.

You had better use find_library command instead of link_directories. Concretely speaking there are two ways:

1. designate the path within the command

   find_library(NAMES gtest PATHS path1 path2 ... pathN)

2. set the variable CMAKE_LIBRARY_PATH

   set(CMAKE_LIBRARY_PATH path1 path2)
   find_library(NAMES gtest)

the reason is as flowings:

Note This command is rarely necessary and should be avoided where there are other choices. Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. The find_library() command provides the full path, which can generally be used directly in calls to target_link_libraries(). Situations where a library search path may be needed include: Project generators like Xcode where the user can switch target architecture at build time, but a full path to a library cannot be used because it only provides one architecture (i.e. it is not a universal binary).

Libraries may themselves have other private library dependencies that expect to be found via RPATH mechanisms, but some linkers are not able to fully decode those paths (e.g. due to the presence of things like $ORIGIN).

If a library search path must be provided, prefer to localize the effect where possible by using the target_link_directories() command rather than link_directories(). The target-specific command can also control how the search directories propagate to other dependent targets.

You don't need two JScrollPanes.

Example:

JTextArea ta = new JTextArea();
JScrollPane sp = new JScrollPane(ta);  

// Add the scroll pane into the content pane
JFrame f = new JFrame();
f.getContentPane().add(sp);

I would have to say SimpleXML takes the cake because it is firstly an extension, written in C, and is very fast. But second, the parsed document takes the form of a PHP object. So you can "query" like $root->myElement.

You can use the parse method from the URL module in the request callback.

var http = require('http');
var url = require('url');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    response.end('Hello ' + queryData.name + '\n');

  } else {
    response.end("Hello World\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8000);

I suggest you read the HTTP module documentation to get an idea of what you get in the createServer callback. You should also take a look at sites like http://howtonode.org/ and checkout the Express framework to get started with Node faster.

I think of it as a large array of binary data. The usability of BLOB follows immediately from the limited bandwidth of the DB interface, it is not determined by the DB storage mechanisms. No matter how you store the large piece of data, the only way to store and retrieve is the narrow database interface. The database is a bottleneck of the system. Why to use it as a file server, which can easily be distributed? Normally you do not want to download the BLOB. You just want the DB to store your BLOB urls. Deposite the BLOBs on a separate file server. Then, you reliefe the precious DB connection and provide unlimited bandwidth for large objects. This creates some issue of coherence though.
