the above is not bad, however its kinda different for 11.10

sudo apt-get install ruby1.9 rubygems1.9

that will install ruby 1.9

when linking, you just use ls /usr/bin | grep ruby it should output ruby1.9.1

so then you sudo ln -sf /usr/bin/ruby1.9.1 /usr/bin/ruby and your off to the races.

Here's what's this TS snippet compiled into (via TS Playground):

define(["require", "exports"], function(require, exports) {
    var Library = (function () {
        function Library() {
        }
        Library.BOOK_SHELF_NONE = "None";
        Library.BOOK_SHELF_FULL = "Full";
        return Library;
    })();
    exports.Library = Library;
});

As you see, both properties defined as public static are simply attached to the exported function (as its properties); therefore they should be accessible as long as you properly access the function itself.

Expires and Cache-Control are "strong caching headers"

Last-Modified and ETag are "weak caching headers"

First the browser check Expires/Cache-Control to determine whether or not to make a request to the server

If have to make a request, it will send Last-Modified/ETag in the HTTP request. If the Etag value of the document matches that, the server will send a 304 code instead of 200, and no content. The browser will load the contents from its cache.

While Ryan is correct, the solution can be much simpler based on what is known about the source of the randomness. To re-state the problem:

• There is a source of randomness, outputting integer numbers in range [0, MAX) with uniform distribution.
• The goal is to produce uniformly distributed random integer numbers in range [rmin, rmax] where 0 <= rmin < rmax < MAX.

In my experience, if the number of bins (or "boxes") is significantly smaller than the range of the original numbers, and the original source is cryptographically strong - there is no need to go through all that rigamarole, and simple modulo division would suffice (like output = rnd.next() % (rmax+1), if rmin == 0), and produce random numbers that are distributed uniformly "enough", and without any loss of speed. The key factor is the randomness source (i.e., kids, don't try this at home with rand()).

Here's an example/proof of how it works in practice. I wanted to generate random numbers from 1 to 22, having a cryptographically strong source that produced random bytes (based on Intel RDRAND). The results are:

Rnd distribution test (22 boxes, numbers of entries in each box):     
 1: 409443    4.55%
 2: 408736    4.54%
 3: 408557    4.54%
 4: 409125    4.55%
 5: 408812    4.54%
 6: 409418    4.55%
 7: 408365    4.54%
 8: 407992    4.53%
 9: 409262    4.55%
10: 408112    4.53%
11: 409995    4.56%
12: 409810    4.55%
13: 409638    4.55%
14: 408905    4.54%
15: 408484    4.54%
16: 408211    4.54%
17: 409773    4.55%
18: 409597    4.55%
19: 409727    4.55%
20: 409062    4.55%
21: 409634    4.55%
22: 409342    4.55%   
total: 100.00%

This is as close to uniform as I need for my purpose (fair dice throw, generating cryptographically strong codebooks for WWII cipher machines such as http://users.telenet.be/d.rijmenants/en/kl-7sim.htm, etc). The output does not show any appreciable bias.

Here's the source of cryptographically strong (true) random number generator: Intel Digital Random Number Generator and a sample code that produces 64-bit (unsigned) random numbers.

int rdrand64_step(unsigned long long int *therand)
{
  unsigned long long int foo;
  int cf_error_status;

  asm("rdrand %%rax; \
        mov $1,%%edx; \
        cmovae %%rax,%%rdx; \
        mov %%edx,%1; \
        mov %%rax, %0;":"=r"(foo),"=r"(cf_error_status)::"%rax","%rdx");
        *therand = foo;
  return cf_error_status;
}

I compiled it on Mac OS X with clang-6.0.1 (straight), and with gcc-4.8.3 using "-Wa,q" flag (because GAS does not support these new instructions).

My two cents. I like simpler an one-line code in python:

>>> from itertools import imap, ifilter
>>> l = ['a', '', 'b', 1, None]
>>> ','.join(imap(str, ifilter(lambda x: x, l)))
a,b,1
>>> m = ['a', '', None]
>>> ','.join(imap(str, ifilter(lambda x: x, m)))
'a'

It's pythonic, works for strings, numbers, None and empty string. It's short and satisfies the requirements. If the list is not going to contain numbers, we can use this simpler variation:

>>> ','.join(ifilter(lambda x: x, l))

Also this solution doesn't create a new list, but uses an iterator, like @Peter Hoffmann pointed (thanks).

There are a couple of libraries out there. onnov/detect-encoding looks promising. It claims to do better than mb_detect_encoding

Example usage for converting string in unknown character encoding to UTF-8:

use Onnov\DetectEncoding\EncodingDetector;
$detector->iconvXtoEncoding('??????????? ?????')

To simply detect encoding:

$encoding = $detector->getEncoding('??????????? ?????');

for(n in 1:5) {
  if(n==3) next # skip 3rd iteration and go to next iteration
  cat(n)
}

Look at where your html file is, the path you provided is relative not absolute. Are you sure it's placed correctly. According to the path you gave in the example above: "src="../js/moment.js" " the JS file is one level higher in hierarchy. So it should be placed as following:

Parent folder sub-folder html file js (this is a folder) moment.js

The double dots means the parent folder from current directory, in your case, the current directory is the location of html file.

But to make your life easier using a server will safe you troubles of doing this manually since the server directory is same all time so it's much easier.

Use the style word-break:break-all;. I know it works on tables.

if you use macOS and can't use readarray, you can simply do this-

MY_STRING="string1 string2 string3"
array=($MY_STRING)

To iterate over the elements:

for element in "${array[@]}"
do
    echo $element
done

You can change the proerty to Task<IEnumerable>

and do something like:

get
{
    Task<IEnumerable>.Run(async()=>{
       return await getMyList();
    });
}

and use it like await MyList;

One can also do this with a compact version of @TomAugspurger's answer, like so:

df = df1.merge(df2, how='left', on=['Year', 'Week', 'Colour']).merge(df3[['Week', 'Colour', 'Val3']], how='left', on=['Week', 'Colour'])

you should do as:

getline(name, sizeofname, '\n');
strtok(name, " ");

This will give you the "joht" in name then to get next token,

temp = strtok(NULL, " ");

temp will get "smith" in it. then you should use string concatination to append the temp at end of name. as:

strcat(name, temp);

(you may also append space first, to obtain a space in between).

Check this out as well: using xml path and pivot

I successfully opened gstreamer SDK tutorials in Eclipse.

All I needed is to use an older version of ndk. specificly 9d.

(10c and 10d does not work, 10b - works just for tutorial-1 )

9d does work for all tutorials ! and you can:

1. Download it from: http://dl.google.com/android/ndk/android-ndk-r9d-linux-x86_64.tar.bz2

2. Extract it.

3. set it in eclipse->window->preferences->Android->NDK->NDK location.

4. build - (ctrl+b).

Here's a simple Python code to calculate cosine similarity:

import math

def dot_prod(v1, v2):
    ret = 0
    for i in range(len(v1)):
        ret += v1[i] * v2[i]
    return ret

def magnitude(v):
    ret = 0
    for i in v:
        ret += i**2
    return math.sqrt(ret)

def cos_sim(v1, v2):
    return (dot_prod(v1, v2)) / (magnitude(v1) * magnitude(v2))

If using the Win32 API you can use the FindFirstFile and FindNextFile functions.

http://msdn.microsoft.com/en-us/library/aa365200(VS.85).aspx

For recursive traversal of directories you must inspect each WIN32_FIND_DATA.dwFileAttributes to check if the FILE_ATTRIBUTE_DIRECTORY bit is set. If the bit is set then you can recursively call the function with that directory. Alternatively you can use a stack for providing the same effect of a recursive call but avoiding stack overflow for very long path trees.

Define one Enum Type as

public enum Colors {
     BLUE, SILVER, MAGENTA, RED
}

Change data type of color from String to Colors Change return type and argument type of getter and setter method of color to Colors

Define comparator type as follows

static class ColorComparator implements Comparator<CarSort>
{
    public int compare(CarSort c1, CarSort c2)
    {
        return c1.getColor().compareTo(c2.getColor());
    }
}

after adding elements to List, call sort method of Collection by passing list and comparator objects as arguments

i.e, Collections.sort(carList, new ColorComparator()); then print using ListIterator.

full class implementation is as follows:

package test;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;    
import java.util.ListIterator;

public class CarSort implements Comparable<CarSort>{

    String name;
    Colors color;

    public CarSort(String name, Colors color){
        this.name = name;
        this.color = color;
    } 

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Colors getColor() {
        return color;
    }
    public void setColor(Colors color) {
        this.color = color;
    }

    //Implement the natural order for this class
    public int compareTo(CarSort c)
    {
        return getName().compareTo(c.getName());
    }

    static class ColorComparator implements Comparator<CarSort>
    {
        public int compare(CarSort c1, CarSort c2)
        {
            return c1.getColor().compareTo(c2.getColor());
        }
    }

    public enum Colors {
         BLUE, SILVER, MAGENTA, RED
    }

     public static void main(String[] args)
     {
         List<CarSort> carList = new ArrayList<CarSort>();
         List<String> sortOrder = new ArrayList<String>();

         carList.add(new CarSort("Ford Figo",Colors.SILVER));
         carList.add(new CarSort("Santro",Colors.BLUE));
         carList.add(new CarSort("Honda Jazz",Colors.MAGENTA));
         carList.add(new CarSort("Indigo V2",Colors.RED));
         Collections.sort(carList, new ColorComparator());

         ListIterator<CarSort> itr=carList.listIterator();
         while (itr.hasNext()) {
            CarSort carSort = (CarSort) itr.next();
            System.out.println("Car colors: "+carSort.getColor());
        }
     }
}

I struggled to get this working. That's why I'll add a complete solution here:

My objective is to add this header to the SOAP envelope:

   <soapenv:Header>
      <urn:OTAuthentication>
         <urn:AuthenticationToken>TOKEN</urn:AuthenticationToken>
      </urn:OTAuthentication>
   </soapenv:Header>

1. First create a SOAPHeaderHandler class.

   import java.util.Set;
   import java.util.TreeSet;
   
   import javax.xml.namespace.QName;
   import javax.xml.soap.SOAPElement;
   import javax.xml.soap.SOAPEnvelope;
   import javax.xml.soap.SOAPFactory;
   import javax.xml.soap.SOAPHeader;
   import javax.xml.ws.handler.MessageContext;
   import javax.xml.ws.handler.soap.SOAPHandler;
   import javax.xml.ws.handler.soap.SOAPMessageContext;
   
   public class SOAPHeaderHandler implements SOAPHandler<SOAPMessageContext> {
   
       private final String authenticatedToken;
   
       public SOAPHeaderHandler(String authenticatedToken) {
           this.authenticatedToken = authenticatedToken;
       }
   
       public boolean handleMessage(SOAPMessageContext context) {
           Boolean outboundProperty =
                   (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
           if (outboundProperty.booleanValue()) {
               try {
                   SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
                   SOAPFactory factory = SOAPFactory.newInstance();
                   String prefix = "urn";
                   String uri = "urn:api.ecm.opentext.com";
                   SOAPElement securityElem =
                           factory.createElement("OTAuthentication", prefix, uri);
                   SOAPElement tokenElem =
                           factory.createElement("AuthenticationToken", prefix, uri);
                   tokenElem.addTextNode(authenticatedToken);
                   securityElem.addChildElement(tokenElem);
                   SOAPHeader header = envelope.addHeader();
                   header.addChildElement(securityElem);
               } catch (Exception e) {
                   e.printStackTrace();
               }
           } else {
               // inbound
           }
           return true;
       }
   
       public Set<QName> getHeaders() {
           return new TreeSet();
       }
   
       public boolean handleFault(SOAPMessageContext context) {
           return false;
       }
   
       public void close(MessageContext context) {
           //
       }
   }
   

   2. Add the handler to the proxy. Note that according javax.xml.ws.Binding's documentation: "If the returned chain is modified a call to setHandlerChain is required to configure the binding instance with the new chain."

   Authentication_Service authentication_Service = new Authentication_Service();
   
   Authentication basicHttpBindingAuthentication = authentication_Service.getBasicHttpBindingAuthentication();
   String authenticatedToken = "TOKEN";
   List<Handler> handlerChain = ((BindingProvider)basicHttpBindingAuthentication).getBinding().getHandlerChain();
   handlerChain.add(new SOAPHeaderHandler(authenticatedToken));
   ((BindingProvider)basicHttpBindingAuthentication).getBinding().setHandlerChain(handlerChain);
   

Since the timestamps are seconds since the UNIX epoch, you can use DateTime.strptime ("string parse time") with the correct specifier:

Date.strptime('1100897479', '%s')
#=> #<Date: 2004-11-19 ((2453329j,0s,0n),+0s,2299161j)>
Date.strptime('1100897479', '%s').to_s
#=> "2004-11-19"
DateTime.strptime('1100897479', '%s')
#=> #<DateTime: 2004-11-19T20:51:19+00:00 ((2453329j,75079s,0n),+0s,2299161j)>
DateTime.strptime('1100897479', '%s').to_s
#=> "2004-11-19T20:51:19+00:00"

Note that you have to require 'date' for that to work, then you can call it either as Date.strptime (if you only care about the date) or DateTime.strptime (if you want date and time). If you need different formatting, you can call DateTime#strftime (look at strftime.net if you have a hard time with the format strings) on it or use one of the built-in methods like rfc822.

Firstly, you need to change this line:

element.setAttribute("onclick", alert("blabla"));

To something like this:

element.setAttribute("onclick", function() { alert("blabla"); });

Secondly, you may have browser compatibility issues when attaching events that way. You might need to use .attachEvent / .addEvent, depending on which browser. I haven't tried manually setting event handlers for a while, but I remember firefox and IE treating them differently.

Consider using jQuery. Life is much easier with:

$('body').hide(); $('body1').show();

As an alternative to the important keyword, you could make the selector more specific, for example:

.left.background-none { background:none; }

(Note: no space between the class names).

In this case, the rule will apply when both .left and .background-none are listed in the class attribute (regardless of the order or proximity).

Now in rails 5 yu can do:

rails restart

This print by rails --tasks

Restart app by touching tmp/restart.txt

I think that is usefully if you run rails as a demon

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/wait.h>

int main (){
    int pid;
    int status;

    printf("Parent: %d\n", getpid());

    pid = fork();
    if (pid == 0){
        printf("Child %d\n", getpid());
        sleep(2);
        exit(EXIT_SUCCESS);
    }

//Comment from here to...
    //Parent waits process pid (child)
    waitpid(pid, &status, 0);
    //Option is 0 since I check it later

    if (WIFSIGNALED(status)){
        printf("Error\n");
    }
    else if (WEXITSTATUS(status)){
        printf("Exited Normally\n");
    }
//To Here and see the difference
    printf("Parent: %d\n", getpid());

    return 0;
}

I tried what kohske wrote as an answer and I got error again, so I did some search and found this which worked for me (R 3.0.2):

require(splines) # package
detach(package:splines)

or also

library(splines)
pkg <- "package:splines"
detach(pkg, character.only = TRUE)

You should use .value and not .innerHTML as it is a input type form element

<html>
  <head>
  <script type="text/javascript">
  function validate() {
  if(myform.fname.value.length==0)
  {
   document.getElementById("fname").value="this is invalid name ";
  }
  }
  </script>
  </head>
  <body>
  <form name="myform">
  First_Name
  <input type=text id=fname name=fname onblur="validate()"> </input>

  <br> <br>
  Last_Name
  <input type=text id=lname name=lname onblur="validate()"> </input>

  <br>
  <input type=button value=check> 

  </form>
  </body>
</html>

The other answers are correct as to "how" to resize them, but I would also thrown in the recommendation to just grab the resolution you are interested in, to begin with. Most Android devices offer a range of resolutions and you should pick one that gives you a file size that you're comfortable with. The biggest reason for this is that the native Android scaling algorithm (as detailed by Jin35 and Padma Kumar) produces pretty crappy results. It's not going to give you Photoshop quality resizing, even downscaling (to say nothing of upscaling, which I know you're not asking about, but that's just a non-starter).

So, you should try their solution and if you're happy with the outcome, great. But if not, I'd write a function that offers a range of width that you're happy with, and looks for that dimension (or whatever's closest) in the device's available picture size array and just set it and use it.

It looks like you were on the right track - get_FOO_display() is most certainly what you want:

In templates, you don't include () in the name of a method. Do the following:

{{ person.get_gender_display }}

Try the snipped which is mentioned below, it works for me also.

In my layout xml where I have my TabLayout, have added style to the TabLayout like below :

<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    style="@style/MyCustomTabLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabGravity="fill"
    app:tabMode="fixed" />

and in my style.xml I have defined the style that is used in my layout xml, check code for styles added below :

I hope it will work for you.....

Best is to just Apply margin-top: 2px on the input element.

Bootstrap adds a margin-top: 4px to input element causing radio button to move down than the content.

My only doubt would be how applicable this technique would be on multi-byte strings, but if that's not a consideration, then I suspect you're covered. (If in doubt, mb_substr() seems an obviously safe choice.)

However, from a big picture perspective, I have to wonder how often you need to access the 'n'th character in a string for this to be a key consideration.

Try this all four way to take input with space :)

#include<iostream>
#include<stdio.h>

using namespace std;

void dinput(char *a)
{
    for(int i=0;; i++)
    {
        cin >> noskipws >> a[i];
        if(a[i]=='\n')
        {
            a[i]='\0';
            break;
        }
    }
}


void input(char *a)
{
    //cout<<"\nInput string: ";

    for(int i=0;; i++)
    {
        *(a+i*sizeof(char))=getchar();

        if(*(a+i*sizeof(char))=='\n')
        {
            *(a+i*sizeof(char))='\0';
            break;
        }

    }
}



int main()
{
    char a[20];

    cout<<"\n1st method\n";
    input(a);
    cout<<a;

    cout<<"\n2nd method\n";
    cin.get(a,10);
    cout<<a;

    cout<<"\n3rd method\n";
    cin.sync();
    cin.getline(a,sizeof(a));
    cout<<a;

    cout<<"\n4th method\n";
    dinput(a);
    cout<<a;

    return 0;
}

Search and replace

outline: thin dotted;
outline: 5px auto -webkit-focus-ring-color;

Replace to

outline: 0;

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

I use varargs frequently for constructors that can take some sort of filter object. For example, a large part of our system based on Hadoop is based on a Mapper that handles serialization and deserialization of items to JSON, and applies a number of processors that each take an item of content and either modify and return it, or return null to reject.

The way to set JFrame to full-screen, is to set MAXIMIZED_BOTH option which stands for MAXIMIZED_VERT | MAXIMIZED_HORIZ, which respectively set the frame to maximize vertically and horizontally

package Example;
import java.awt.GraphicsConfiguration;
import javax.swing.JFrame;
import javax.swing.JButton;

public class JFrameExample
{
    static JFrame frame;
    static GraphicsConfiguration gc;
    public static void main(String[] args)
    {
        frame = new JFrame(gc);
        frame.setTitle("Full Screen Example");
        frame.setExtendedState(MAXIMIZED_BOTH);

        JButton button = new JButton("exit");
        b.addActionListener(new ActionListener(){@Override
        public void actionPerformed(ActionEvent arg0){
            JFrameExample.frame.dispose();
            System.exit(0);
        }});

        frame.add(button);
        frame.setVisible(true);
    }
}

There is an awesome set of services available called MongoDB Stitch. Look into stitch functions/triggers. Note this is a cloud-based paid service (AWS). In your case, on an insert, you could call a custom function written in javascript.

The property you are looking for that first td is rowspan: http://www.angelfire.com/fl5/html-tutorial/tables/tr_code.htm

<table>
<tr><td rowspan="2"></td><td colspan='4'></td></tr>
<tr><td></td><td></td><td></td><td></td></tr>
<tr><td></td><td></td><td></td><td></td><td></td></tr>
</table>

If you're not tagetting IE6, then float the second <div> and give it a margin equal to (or maybe a little bigger than) the first <div>'s fixed width.

HTML:

<div id="main-wrapper">
    <div id="fixed-width"> lorem ipsum </div>
    <div id="rest-of-space"> dolor sit amet </div>
</div>

CSS:

#main-wrapper {
    100%;
    background:red;
}
#fixed-width {
    width:100px;
    float:left
}
#rest-of-space {
    margin-left:101px;
        /* May have to increase depending on borders and margin of the fixd width div*/
    background:blue;
}

The margin accounts for the possibility that the 'rest-of-space' <div> may contain more content than the 'fixed-width' <div>.

Don't give the fixed width one a background; if you need to visibly see these as different 'columns' then use the Faux Columns trick.

I'm really late to party here, but most of the answers seem to be about the whys and whens of using assertions in general, rather than using AssertionError in particular.

assert and throw new AssertionError() are very similar and serve the same conceptual purpose, but there are differences.

1. throw new AssertionError() will throw the exception regardless of whether assertions are enabled for the jvm (i.e., through the -ea switch).
2. The compiler knows that throw new AssertionError() will exit the block, so using it will let you avoid certain compiler errors that assert will not.

For example:

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            throw new AssertionError();
        }
        System.out.println("n = " + n);
    }

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            assert false;
        }
        System.out.println("n = " + n);
    }

The first block, above, compiles just fine. The second block does not compile, because the compiler cannot guarantee that n has been initialized by the time the code tries to print it out.

It depends on the task you want to do, but I wouldn't use it. Also, check if the thread-save-ness you want to accompish couldn't be done by synchronize(this) in the first place? There are also some nice locks in the API that might help you :)

PDFJet offers an open-source version of their library that should be able to handle any basic PDF generation task. It's a purely Java-based solution and it is stated to be compatible with Android. There is a commercial version with some additional features that does not appear to be too expensive.

char *p = "String";   means pointer to a string type variable.

char p3[5] = "String"; means you are pre-defining the size of the array to consist of no more than 5 elements. Note that,for strings the null "\0" is also considered as an element.So,this statement would give an error since the number of elements is 7 so it should be:

char p3[7]= "String";

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

You need to import FormsModule in your root module if this component is in the root i.e. app.module.ts

Kindly open app.module.ts

Import FormsModule from @angular/forms

Ex:

import { FormsModule } from '@angular/forms';

and

@NgModule({
imports: [
   FormsModule
],
})

You can make a plain controller file like

php artisan make:controller --plain <controller name>

I wanted to expand on the answer that Brian contributed to make this easily usable in other places.

/// <summary>
/// This will add an array of parameters to a SqlCommand. This is used for an IN statement.
/// Use the returned value for the IN part of your SQL call. (i.e. SELECT * FROM table WHERE field IN (returnValue))
/// </summary>
/// <param name="sqlCommand">The SqlCommand object to add parameters to.</param>
/// <param name="array">The array of strings that need to be added as parameters.</param>
/// <param name="paramName">What the parameter should be named.</param>
protected string AddArrayParameters(SqlCommand sqlCommand, string[] array, string paramName)
{
    /* An array cannot be simply added as a parameter to a SqlCommand so we need to loop through things and add it manually. 
     * Each item in the array will end up being it's own SqlParameter so the return value for this must be used as part of the
     * IN statement in the CommandText.
     */
    var parameters = new string[array.Length];
    for (int i = 0; i < array.Length; i++)
    {
        parameters[i] = string.Format("@{0}{1}", paramName, i);
        sqlCommand.Parameters.AddWithValue(parameters[i], array[i]);
    }

    return string.Join(", ", parameters);
}

You can use this new function as follows:

SqlCommand cmd = new SqlCommand();

string ageParameters = AddArrayParameters(cmd, agesArray, "Age");
sql = string.Format("SELECT * FROM TableA WHERE Age IN ({0})", ageParameters);

cmd.CommandText = sql;

public static class Extensions
{
    public static void AddArrayParameters<T>(this SqlCommand cmd, string name, IEnumerable<T> values) 
    { 
        name = name.StartsWith("@") ? name : "@" + name;
        var names = string.Join(", ", values.Select((value, i) => { 
            var paramName = name + i; 
            cmd.Parameters.AddWithValue(paramName, value); 
            return paramName; 
        })); 
        cmd.CommandText = cmd.CommandText.Replace(name, names); 
    }
}

You can then use this extension method as follows:

var ageList = new List<int> { 1, 3, 5, 7, 9, 11 };
var cmd = new SqlCommand();
cmd.CommandText = "SELECT * FROM MyTable WHERE Age IN (@Age)";    
cmd.AddArrayParameters("Age", ageList);

Make sure you set the CommandText before calling AddArrayParameters.

Also make sure your parameter name won't partially match anything else in your statement (i.e. @AgeOfChild)

For me, I had to install Microsoft Access Database Engine 2010 Redistributable and restart my computer.

You could create two handlers for file and stdout and then create one logger with handlers argument to basicConfig. It could be useful if you have the same log_level and format output for both handlers:

import logging
import sys

file_handler = logging.FileHandler(filename='tmp.log')
stdout_handler = logging.StreamHandler(sys.stdout)
handlers = [file_handler, stdout_handler]

logging.basicConfig(
    level=logging.DEBUG, 
    format='[%(asctime)s] {%(filename)s:%(lineno)d} %(levelname)s - %(message)s',
    handlers=handlers
)

logger = logging.getLogger('LOGGER_NAME')

You missed title in <a> element.

<h1 id="logo">
  <a href="#" title="..."><span>Stack Overflow</span></a>
</h1>

I suggest to put title in <a> element because client would want to know what is the meaning of that image. Because you have set text-indent for the test of <h1> so, that front end user could get information of main logo while they hover on logo.

if you want your datetime.now() precise till the minute , you can use

datetime.strptime(datetime.now().strftime('%Y-%m-%d %H:%M'), '%Y-%m-%d %H:%M')

similarly for hour it will be

datetime.strptime(datetime.now().strftime('%Y-%m-%d %H'), '%Y-%m-%d %H')

It is kind of a hack, if someone has a better solution, I am all ears

$('element[name="element_name"]').click(function(){
    //do stuff
});

in your case:

$('input[name="btnName"]').click(function(){
    //do stuff
});

It seems that in the debug log for Java 6 the request is send in SSLv2 format.

main, WRITE: SSLv2 client hello message, length = 110

This is not mentioned as enabled by default in Java 7.
Change the client to use SSLv3 and above to avoid such interoperability issues.

Look for differences in JSSE providers in Java 7 and Java 6

This works with Android 6.0 (debuggable apps at least):

adb shell "run-as your.package.name cp /data/data/your.package.name/databases/you-db-name  /sdcard/file_to_write"

Then you simply can view the DB with aSQLiteManager for instance.

I faced a similar problem, here's how I solved in my case. I verify if the task already is RUNNING or FINISHED because an task can run only once. Below you will see a partial and adapted code from my solution.

public class MyActivity... {
    private MyTask task;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
       // your code
       task = new MyTask();
       setList();
    }

    private void setList() {
    if (task != null)
        if (task.getStatus().equals(AsyncTask.Status.RUNNING)){
            task.cancel(true);
            task = new MyTask();
            task.execute();         
        } else if (task.getStatus().equals(AsyncTask.Status.FINISHED)) {
            task = new MyTask();
            task.execute();
        } else 
            task.execute();
    }

    class MyTask extends AsyncTask<Void, Item, Void>{
       List<Item> Itens;

       @Override
       protected void onPreExecute() {

        //your code

        list.setVisibility(View.GONE);
        adapterItem= new MyListAdapter(MyActivity.this, R.layout.item, new ArrayList<Item>());
        list.setAdapter(adapterItem);

        adapterItem.notifyDataSetChanged();
    }

    @Override
    protected Void doInBackground(Void... params) {

        Itens = getItens();
        for (Item item : Itens) {
            publishProgress(item );
        }

        return null;
    }

    @Override
    protected void onProgressUpdate(Item ... item ) {           
        adapterItem.add(item[0]);
    }

    @Override
    protected void onPostExecute(Void result) {
        //your code
        adapterItem.notifyDataSetChanged();     
        list.setVisibility(View.VISIBLE);
    }

}

}

I was having the same issue, if you have enabled Display intranet sites in Compatibility View the polyfills.ts won't work, you still need to add the following line as has been told.

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

getline is storing the entire line at once, which is not what you want. A simple fix is to have three variables and use cin to get them all. C++ will parse automatically at the spaces.

#include <iostream>
using namespace std;

int main() {
    string a, b, c;
    cin >> a >> b >> c;
    //now you have your three words
    return 0;
}

I don't know what particular "operation" you're talking about, so I can't help you there, but if it's changing characters, read up on string and indices. The C++ documentation is great. As for using namespace std; versus std:: and other libraries, there's already been a lot said. Try these questions on StackOverflow to start.

When you use git push origin :staleStuff, it automatically removes origin/staleStuff, so when you ran git remote prune origin, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune to get rid of branches you have removed.

So what exactly git remote prune does? Main idea: local branches (not tracking branches) are not touched by git remote prune command and should be removed manually.

Now, a real-world example for better understanding:

You have a remote repository with 2 branches: master and feature. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):

• refs/heads/master (short name master)
• refs/heads/feature (short name feature)
• refs/remotes/origin/master (short name origin/master)
• refs/remotes/origin/feature (short name origin/feature)

Now, a typical scenario:

1. Some other developer finishes all work on the feature, merges it into master and removes feature branch from remote repository.
2. By default, when you do git fetch (or git pull), no references are removed from your local repository, so you still have all those 4 references.
3. You decide to clean them up, and run git remote prune origin.
4. git detects that feature branch no longer exists, so refs/remotes/origin/feature is a stale branch which should be removed.
5. Now you have 3 references, including refs/heads/feature, because git remote prune does not remove any refs/heads/* references.

It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge configuration parameter. This parameter is not really required for anything to work (probably except git pull), so it might be missing.

(updated with example & useful info from comments)

You use the ajaxStop to execute code when the ajax are completed:

$(document).ajaxStop(function(){
  setTimeout("window.location = 'otherpage.html'",100);
});

The problem is probably coming from the fact that Date is deprecated.

Consider using

java.util.Calendar

or

Joda-Time

Edit 2015:

Java 8 and later has built-in the new java.time package, which is similar to Joda-Time.

I think this is important to consider for cross-platform execution, i.e. as a CYA. :)

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

This is directly quoted from Python Software Foundation 2.7.x.

For info : in some Apache2 conf you must add the DirectoryIndex command in mods_enabled/dir.conf (it's not located in apache2.conf)

There are a couple ways to do this.

First, instead of going into openssl command prompt mode, just enter everything on one command line from the Windows prompt:

E:\> openssl x509 -pubkey -noout -in cert.pem  > pubkey.pem

If for some reason, you have to use the openssl command prompt, just enter everything up to the ">". Then OpenSSL will print out the public key info to the screen. You can then copy this and paste it into a file called pubkey.pem.

openssl> x509 -pubkey -noout -in cert.pem

Output will look something like this:

Make the method type [HttpPost], create a model that has one int[] parameter, and post with json:

/* Model */
public class CategoryRequestModel 
{
    public int[] Categories { get; set; }
}

/* WebApi */
[HttpPost]
public HttpResponseMessage GetCategories(CategoryRequestModel model)
{
    HttpResponseMessage resp = null;

    contentType: 'application/json',
    success: function(data, textStatus, jqXHR)
    {
        //get categories from data
    }
};

$.ajax(ajaxSettings);

Another (and in my opinion proper) method is use the __FILE__ constant if you don't like to rely on $_SERVER variables.

$parts = explode(DIRECTORY_SEPARATOR, __FILE__);
$fileName = end($parts);
echo $fileName;

About magic and predefined constants: 1, 2.

Surround it with a div and give it a border and remove the border from the table

<div style="border: 1px solid black">
    <table border="0">
        <tr>
            <td>one</td>
            <td>two</td>
        </tr>
        <tr>
            <td>one</td>
            <td>two</td>
        </tr>
    </table>
</div>

You can check the working fiddle here

As per your updated question .... where you want to add or remove borders. You should remove borders from the html table first and then do the following

<td style="border-top: 1px solid black">

Assuming like you only want the top border. Similarly you have to do for others. Better way create four css class...

.topBorderOnly {
    border-top: 1px solid black;
}

.bottomBorderOnly {
    border-bottom: 1px solid black;
}

Then add the css to your code depending on the requirements.

<td class="topBorderOnly bottomBorderOnly">  

This will add both top and bottom border, similarly do for the rest.

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

ax.set_title() should set the titles for separate subplots:

import matplotlib.pyplot as plt

if __name__ == "__main__":
    data = [1, 2, 3, 4, 5]

    fig = plt.figure()
    fig.suptitle("Title for whole figure", fontsize=16)
    ax = plt.subplot("211")
    ax.set_title("Title for first plot")
    ax.plot(data)

    ax = plt.subplot("212")
    ax.set_title("Title for second plot")
    ax.plot(data)

    plt.show()

Can you check if this code works for you? Maybe something overwrites them later?

You should need to convert your PHP array to javascript array using PHP syntax json_encode. json_encode convert PHP array to JSON string

Single Dimension PHP array to javascript array

<?php
var $itemsarray= array("Apple", "Bear", "Cat", "Dog");
?>
<script>
var items= <?php echo json_encode($itemsarray); ?>;
console.log(items[2]); // Output: Bear
// OR
alert(items[0]); // Output: Apple
</script>

Multi Dimension PHP array to javascript array

<?php
var $itemsarray= array( 
               array('name'='Apple', 'price'=>'12345'),
               array('name'='Bear', 'price'=>'13344'),
               array('name'='Potato', 'price'=>'00440')
             );
?>


<script>
var items= <?php echo json_encode($itemsarray); ?>;
console.log(items[1][name]); // Output: Bear
// OR
alert(items[0][price]); // Output: Apple
</script>

For more detail, you can also check php array to javascript array

Problem is that while runtime generic type is erased so new E[10] would be equivalent to new Object[10].

This would be dangerous because it would be possible to put in array other data than of E type. That is why you need to explicitly say that type you want by either

• creating Object array and cast it to E[] array, or
• useing Array.newInstance(Class componentType, int length) to create real instance of array of type passed in componentType argiment.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

MimeTypeMap.getSingleton().getExtensionFromMimeType(file.getName());

Probably, this is the easiest solution.

https://developer.android.com/reference/android/webkit/MimeTypeMap

https://developer.android.com/reference/java/net/URLConnection.html#guessContentTypeFromName(java.lang.String)

private void openFile(File file) {

    Uri uri = Uri.fromFile(file);

    Intent intent = new Intent(Intent.ACTION_VIEW);

    intent.setDataAndType(uri, MimeTypeMap.getSingleton().getExtensionFromMimeType(file.getName()));


    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(Intent.createChooser(intent, "Open " + file.getName() + " with ..."));
}

Your question implies that you're building the INSERT statement up by concatenating strings together. I suggest that this is a poor choice as it leaves you open to SQL injection attacks if the strings are derived from user input. A better choice is to use parameter markers and to bind the values to the markers. If you search for Oracle parameter markers you'll probably find some information for your specific implementation technology (e.g. C# and ADO, Java and JDBC, Ruby and RubyDBI, etc).

Use the % wildcard, which matches any number of characters.

SELECT * FROM Accounts WHERE Username LIKE '%query%'

Use JavaScript's hasOwnProperty() function:

if (json_object.hasOwnProperty('name')) {
    //do struff
}

editText.setInputType(InputType.TYPE_NULL);

As per the docs this prevents the soft keyboard from being displayed. It also prevents pasting, allows scrolling and doesn't alter the visual aspect of the view. However, this also prevents selecting and copying of the text within the view.

From my tests setting setInputType to TYPE_NULL seems to be functionally equivalent to the depreciated android:editable="false". Additionally, android:inputType="none" seems to have no noticeable effect.

In order to feed the subject and show swift subscript possibilities, here's a little string "substring-toolbox" subscript based

These methods are safe and never go over string indexes

extension String {
    // string[i] -> one string char
    subscript(pos: Int) -> String { return String(Array(self)[min(self.length-1,max(0,pos))]) }

    // string[pos,len] -> substring from pos for len chars on the left
    subscript(pos: Int, len: Int) -> String { return self[pos, len, .pos_len, .left2right] }

    // string[pos, len, .right2left] -> substring from pos for len chars on the right
    subscript(pos: Int, len: Int, way: Way) -> String { return self[pos, len, .pos_len, way] }

    // string[range] -> substring form start pos on the left to end pos on the right
    subscript(range: Range<Int>) -> String { return self[range.startIndex, range.endIndex, .start_end, .left2right] }

    // string[range, .right2left] -> substring start pos on the right to end pos on the left
    subscript(range: Range<Int>, way: Way) -> String { return self[range.startIndex, range.endIndex, .start_end, way] }

    var length: Int { return countElements(self) }
    enum Mode { case pos_len, start_end }
    enum Way { case left2right, right2left }
    subscript(var val1: Int, var val2: Int, mode: Mode, way: Way) -> String {
        if mode == .start_end {
            if val1 > val2 { let val=val1 ; val1=val2 ; val2=val }
            val2 = val2-val1
        }
        if way == .left2right {
            val1 = min(self.length-1, max(0,val1))
            val2 = min(self.length-val1, max(1,val2))
        } else {
            let val1_ = val1
            val1 = min(self.length-1, max(0, self.length-val1_-val2 ))
            val2 = max(1, (self.length-1-val1_)-(val1-1) )
        }

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

svn log - I'm sure WebSVN has some feature for that too.

The "View Log" link near the center-top of the WebSVN overview shows the svn-log. However, the user-interface isn't exactly brilliant; I much prefer TortoiseSVN's log viewer.

So the simplest way is,

alter table table_name change column_name column_name int(11) NULL;

And there is another possibility (not in this case) when working with ajax(XMLhttpRequest), while sending information back to the client end you should use res.send(responsetext) instead of res.end(responsetext)

Alert boxes in JavaScript can only display pure text. You could use a JavaScript library like jQuery to display a modal instead?

This might be useful: http://jqueryui.com/dialog/

You can do it like this:

<!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8" />
  <title>jQuery UI Dialog - Default functionality</title>
  <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />

  <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
  <script>
  body {
    font-family: "Trebuchet MS", "Helvetica", "Arial",  "Verdana", "sans-serif";
    font-size: 62.5%;
}

  </script>
  <script>
  $(function() {
    $( "#dialog" ).dialog();
  });
  </script>
</head>
<body>

Specifying the height of the video will change the quality accordingly. example for html 5;

<iframe style='width:100%; height:800px;' src='https://www.youtube.com/embed/xxxxxxxx'></iframe>

If you don't want to hardcode the width and height you can add a class to the iframe for css media queries.

Tested on a working server + passes the w3.org nuhtml validator.

In my case, it's a typo caused this issue:

<VirtualHost *.8080>

should be

<VirtualHost *:8080>

If you want no output at all this is the most simple way:

robocopy src dest > nul

If you still need some information and only want to strip parts of the output, use the parameters from R.Koene's answer.

The toString method of array types in Java isn't particularly meaningful, other than telling you what that is an array of.

You can use java.util.Arrays.toString for that.

Or if your lines only contain numbers, and you want a line as 1,2,3,4... instead of [1, 2, 3, ...], you can use:

java.util.Arrays.toString(someArray).replaceAll("\\]| |\\[","")

You just need to change some files. This works for me.

Notepad++ has a very powerful editing capability. (Today I'm searching for the similar function in Sublime Text), but for Notepad++, just hold Alt when you drag the mouse. What you type will then replace the selected column on every line. To insert without replacing existing text, use Alt-Shift.

You have to click on query window just below the phpMyAdmin logo, a new window will open. Just click on SQL History tab. There you can see history of SQL Queries.

See my answer to a similar question here.

It sounds like you want a background-image to keep it's own aspect ratio while expanding to 100% width and getting cropped off on the top and bottom. If that's the case, do something like this:

.chapter {
    position: relative;
    height: 1200px;
    z-index: 1;
}

#chapter1 {
    background-image: url(http://omset.files.wordpress.com/2010/06/homer-simpson-1-264a0.jpg);
    background-repeat: no-repeat;
    background-size: 100% auto;
    background-position: center top;
    background-attachment: fixed;
}

jsfiddle: http://jsfiddle.net/ndKWN/3/

The problem with this approach is that you have the container elements at a fixed height, so there can be space below if the screen is small enough.

If you want the height to keep the image's aspect ratio, you'll have to do something like what I wrote in an edit to the answer I linked to above. Set the container's height to 0 and set the padding-bottom to the percentage of the width:

.chapter {
    position: relative;
    height: 0;
    padding-bottom: 75%;
    z-index: 1;
}

#chapter1 {
    background-image: url(http://omset.files.wordpress.com/2010/06/homer-simpson-1-264a0.jpg);
    background-repeat: no-repeat;
    background-size: 100% auto;
    background-position: center top;
    background-attachment: fixed;
}

jsfiddle: http://jsfiddle.net/ndKWN/4/

You could also put the padding-bottom percentage into each #chapter style if each image has a different aspect ratio. In order to use different aspect ratios, divide the height of the original image by it's own width, and multiply by 100 to get the percentage value.

I started using the AngiesList.Redis.RedisSessionStateModule, which aside from using the (very fast) Redis server for storage (I'm using the windows port -- though there is also an MSOpenTech port), it does absolutely no locking on the session.

In my opinion, if your application is structured in a reasonable way, this is not a problem. If you actually need locked, consistent data as part of the session, you should specifically implement a lock/concurrency check on your own.

MS deciding that every ASP.NET session should be locked by default just to handle poor application design is a bad decision, in my opinion. Especially because it seems like most developers didn't/don't even realize sessions were locked, let alone that apps apparently need to be structured so you can do read-only session state as much as possible (opt-out, where possible).

JSfiddle

function deleteEmpty(obj){
        for(var k in obj)
         if(k == "children"){
             if(obj[k]){
                     deleteEmpty(obj[k]);
             }else{
                   delete obj.children;
              } 
         }
    }

for(var i=0; i< a.children.length; i++){
 deleteEmpty(a.children[i])
}

Add your <script> to the bottom of your <body>, or add an event listener for DOMContentLoaded following this StackOverflow question.

If that script executes in the <head> section of the code, document.getElementsByClassName(...) will return an empty array because the DOM is not loaded yet.

You're getting the Type Error because you're referencing search_span[0], but search_span[0] is undefined.

This works when you execute it in Dev Tools because the DOM is already loaded.

This might be easier to explain with a sample dataset.

Create Sample Data

Let's assume we have a single column of Timestamps, date and another column we would like to perform an aggregation on, a.

df = pd.DataFrame({'date':pd.DatetimeIndex(['2012-1-1', '2012-6-1', '2015-1-1', '2015-2-1', '2015-3-1']),
                   'a':[9,5,1,2,3]}, columns=['date', 'a'])

df

        date  a
0 2012-01-01  9
1 2012-06-01  5
2 2015-01-01  1
3 2015-02-01  2
4 2015-03-01  3

There are several ways to group by year

• Use the dt accessor with year property
• Put date in index and use anonymous function to access year
• Use resample method
• Convert to pandas Period

.dt accessor with year property

When you have a column (and not an index) of pandas Timestamps, you can access many more extra properties and methods with the dt accessor. For instance:

df['date'].dt.year

0    2012
1    2012
2    2015
3    2015
4    2015
Name: date, dtype: int64

We can use this to form our groups and calculate some aggregations on a particular column:

df.groupby(df['date'].dt.year)['a'].agg(['sum', 'mean', 'max'])

      sum  mean  max
date                
2012   14     7    9
2015    6     2    3

put date in index and use anonymous function to access year

If you set the date column as the index, it becomes a DateTimeIndex with the same properties and methods as the dt accessor gives normal columns

df1 = df.set_index('date')
df1.index.year

Int64Index([2012, 2012, 2015, 2015, 2015], dtype='int64', name='date')

Interestingly, when using the groupby method, you can pass it a function. This function will be implicitly passed the DataFrame's index. So, we can get the same result from above with the following:

df1.groupby(lambda x: x.year)['a'].agg(['sum', 'mean', 'max'])

      sum  mean  max
2012   14     7    9
2015    6     2    3

Use the resample method

If your date column is not in the index, you must specify the column with the on parameter. You also need to specify the offset alias as a string.

df.resample('AS', on='date')['a'].agg(['sum', 'mean', 'max'])

             sum  mean  max
date                       
2012-01-01  14.0   7.0  9.0
2013-01-01   NaN   NaN  NaN
2014-01-01   NaN   NaN  NaN
2015-01-01   6.0   2.0  3.0

Convert to pandas Period

You can also convert the date column to a pandas Period object. We must pass in the offset alias as a string to determine the length of the Period.

df['date'].dt.to_period('A')

0   2012
1   2012
2   2015
3   2015
4   2015
Name: date, dtype: object

We can then use this as a group

df.groupby(df['date'].dt.to_period('Y'))['a'].agg(['sum', 'mean', 'max'])


      sum  mean  max
2012   14     7    9
2015    6     2    3

Please note on iPad Safari, NoviceCoding's solution won't work if you have -webkit-overflow-scrolling: touch; somewhere in your CSS. The solution is either removing all the occurrences of -webkit-overflow-scrolling: touch; or putting -webkit-overflow-scrolling: auto; with NoviceCoding's solution.

Assuming you are using this for a web service, you can just apply the following attribute to the class:

[System.Web.Script.Services.ScriptService]

Then the following attribute to each method that should return Json:

[ScriptMethod(ResponseFormat = ResponseFormat.Json)]

And set the return type for the methods to be "object"

You need the Clear() function on the list, like so.

List<object> myList = new List<object>();

myList.Add(new object()); // Add something to the list

myList.Clear() // Our list is now empty

fscanf - "On success, the function returns the number of items successfully read. This count can match the expected number of readings or be less -even zero- in the case of a matching failure. In the case of an input failure before any data could be successfully read, EOF is returned."

So, instead of doing nothing with the return value like you are right now, you can check to see if it is == EOF.

You should check for EOF when you call fscanf, not check the array slot for EOF.

Here are a couple of alternative ways of doing it, that may be faster or more suitable than KennyTM's answer, depending on the context.

1) use a regular expression:

import re
words_re = re.compile("|".join(list_of_words))

if words_re.search('some one long two phrase three'):
   # do logic you want to perform

2) You could use sets if you want to match whole words, e.g. you do not want to find the word "the" in the phrase "them theorems are theoretical":

word_set = set(list_of_words)
phrase_set = set('some one long two phrase three'.split())
if word_set.intersection(phrase_set):
    # do stuff

Of course you can also do whole word matches with regex using the "\b" token.

The performance of these and Kenny's solution are going to depend on several factors, such as how long the word list and phrase string are, and how often they change. If performance is not an issue then go for the simplest, which is probably Kenny's.

Perhaps you might want to use "addEventListener"

document.getElementById("test").addEventListener('click',function ()
{
    foo2();
   }  ); 

Hope it's still useful for you

The proper data type for "2010-12-20 00:00:00.0000000" value is DATETIME2(7) / DT_DBTIME2 ().

But used data type for CYCLE_DATE field is DATETIME - DT_DATE. This means milliseconds precision with accuracy down to every third millisecond (yyyy-mm-ddThh:mi:ss.mmL where L can be 0,3 or 7).

The solution is to change CYCLE_DATE date type to DATETIME2 - DT_DBTIME2.

There is no simple way to achieves this directly. But P99 has macros that allow you to create such type of function automatically:

 P99_DECLARE_ENUM(color, red, green, blue);

in a header file, and

 P99_DEFINE_ENUM(color);

in one compilation unit (.c file) should then do the trick, in that example the function then would be called color_getname.

Here is the simple lodash function with array and deleting it with the index number.

index_tobe_delete = 1

fruit = [{a: "apple"}, {b: "banana"}, {c: "choco"}]
_.filter(fruit, (value, key)=> {
return (key !== index_tobe_delete)
})

• Query and get the container DOM element

• Create new element

• Put new element to document Tree

//Query some Dib region you Created
let container=document.querySelector("#CalculationInfo .row .t-Form-itemWrapper");
let input = document.createElement("input");

//create new Element  for apex
input.setAttribute("type","text");
input.setAttribute("size","30");
containter.appendChild(input); // put it into the DOM

You can use whereIn which accepts an array as second paramter.

DB:table('table')
   ->whereIn('column', [value, value, value])
   ->get()

You can chain where multiple times.

DB:table('table')->where('column', 'operator', 'value')
    ->where('column', 'operator', 'value')
    ->where('column', 'operator', 'value')
    ->get();

This will use AND operator. if you need OR you can use orWhere method.

For advanced where statements

DB::table('table')
    ->where('column', 'operator', 'value')
    ->orWhere(function($query)
    {
        $query->where('column', 'operator', 'value')
            ->where('column', 'operator', 'value');
    })
    ->get();

When using jQuery, the usage of $ symbol as a prefix in the variable name is merely by convention; it is completely optional and serves only to indicate that the variable holds a jQuery object, as in your example.

This means that when another jQuery function needs to be called on the object, you wouldn't need to wrap it in $() again. For instance, compare these:

// the usual way
var item = $(this).parent().parent().find('input');
$(item).hide(); // this is a double wrap, but required for code readability
item.hide(); // this works but is very unclear how a jQuery function is getting called on this 

// with $ prefix
var $item = $(this).parent().parent().find('input');
$item.hide(); // direct call is clear
$($item).hide(); // this works too, but isn't necessary

With the $ prefix the variables already holding jQuery objects are instantly recognizable and the code more readable, and eliminates double/multiple wrapping with $().

def find_pairs(L,sum):
    s = set(L)
    edgeCase = sum/2
    if L.count(edgeCase) ==2:
        print edgeCase, edgeCase
    s.remove(edgeCase)      
    for i in s:
        diff = sum-i
        if diff in s: 
            print i, diff


L = [2,45,7,3,5,1,8,9]
sum = 10

Methodology: a + b = c, so instead of looking for (a,b) we look for a = c - b

To replace from the right:

def replace_right(source, target, replacement, replacements=None):
    return replacement.join(source.rsplit(target, replacements))

In use:

>>> replace_right("asd.asd.asd.", ".", ". -", 1)
'asd.asd.asd. -'

For Each row As DataRow In dtDataTable.Rows
    strDetail = row.Item("Detail")
Next row

There's also a shorthand:

For Each row As DataRow In dtDataTable.Rows
    strDetail = row("Detail")
Next row

Note that Microsoft's style guidelines for .Net now specifically recommend against using hungarian type prefixes for variables. Instead of "strDetail", for example, you should just use "Detail".

Best way to solve this until a fix is available (if a fix comes) is to force IE compatibility mode on the user.

Use <META http-equiv="X-UA-Compatible" content="IE=9"> ideally in the masterpage so all pages in your site get the workaround.

You could try the search feature in pip,

$ pip search yaml

which looks for packages in PyPI with yaml in the short description. That reveals various packages, including PyYaml, yamltools, and PySyck, among others (Note that PySyck docs recommend using PyYaml, since syck is out of date). Now you know a specific package name, you can install it:

$ pip install pyyaml

If you want to install python yaml system-wide in linux, you can also use a package manager, like aptitude or yum:

$ sudo apt-get install python-yaml
$ sudo yum install python-yaml

There are lot of different Timers in the .NET BCL:

• System.Timers.Timer
• System.Threading.Timer
• System.Windows.Forms.Timer
• System.Web.UI.Timer
• System.Windows.Threading.DispatcherTimer

When to use which?

• System.Timers.Timer, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
• System.Threading.Timer, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
• System.Windows.Forms.Timer (.NET Framework only), a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment; it executes on the UI thread.
• System.Web.UI.Timer (.NET Framework only), an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.
• System.Windows.Threading.DispatcherTimer, a timer that's integrated into the Dispatcher queue. This timer is processed with a specified priority at a specified time interval.

Source

Some of them needs explicit Start call to begin ticking (for example System.Timers, System.Windows.Forms). And an explicit Stop to finish ticking.

using TimersTimer = System.Timers.Timer;

static void Main(string[] args)
{
    var timer = new TimersTimer(1000);
    timer.Elapsed += (s, e) => Console.WriteLine("Beep");
    Thread.Sleep(1000); //1 second delay
    timer.Start();
    Console.ReadLine();
    timer.Stop();

}

While on the other hand there are some Timers (like: System.Threading) where you don't need explicit Start and Stop calls. (The provided delegate will run a background thread.) Your timer will tick until you or the runtime dispose it.

So, the following two versions will work in the same way:

using ThreadingTimer = System.Threading.Timer;

static void Main(string[] args)
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
    Console.ReadLine();
}

using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
    StartTimer();
    Console.ReadLine();
}

static void StartTimer()
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

But if your timer disposed then it will stop ticking obviously.

using ThreadingTimer = System.Threading.Timer; 

static void Main(string[] args)
{
    StartTimer();
    GC.Collect(0);
    Console.ReadLine();
}

static void StartTimer()
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

As @Bruno suggested, using pytest fixtures is another solution that is accessible for both test classes or even just simple test functions. Here's an example testing python2.7 functions:

import pytest

@pytest.fixture(scope='function')
def some_resource(request):
    stuff_i_setup = ["I setup"]

    def some_teardown():
        stuff_i_setup[0] += " ... but now I'm torn down..."
        print stuff_i_setup[0]
    request.addfinalizer(some_teardown)

    return stuff_i_setup[0]

def test_1_that_needs_resource(some_resource):
    print some_resource + "... and now I'm testing things..."

So, running test_1... produces:

I setup... and now I'm testing things...
I setup ... but now I'm torn down...

Notice that stuff_i_setup is referenced in the fixture, allowing that object to be setup and torn down for the test it's interacting with. You can imagine this could be useful for a persistent object, such as a hypothetical database or some connection, that must be cleared before each test runs to keep them isolated.

Zues77 has the right idea. The OP didn't say "how can i hack my way through this". OP wanted to know how to permanently append to $PATH:

sudo nano /etc/profile

This is where it is set for everything and is the best place to change it for all things needing $PATH

Create a class and put all your code in there and call an instance of this class from the Main :

static void Main(string[] args)
{

    MyClass cls  = new MyClass();
    Console.Write("Write a number: ");
    long a= Convert.ToInt64(Console.ReadLine()); // a is the number given by the user
    long av = cls.volteado(a);
    bool isTrue = cls.siprimo(a);
    ......etc

}

A other users suggested,

.empty()

is good enought, because it removes all descendant nodes (both tag-nodes and text-nodes) AND all kind of data stored inside those nodes. See the JQuery's API empty documentation.

If you wish to keep data, like event handlers for example, you should use

.detach()

as described on the JQuery's API detach documentation.

The method .remove() could be usefull for similar purposes.

1. Change the TIME_ZONE to your local time zone, and keep USE_TZ as True in 'setting.py':

   TIME_ZONE = 'Asia/Shanghai'

   USE_I18N = True

   USE_L10N = True

   USE_TZ = True

2. This will write and store the datetime object as UTC to the backend database.

3. Then use template tag to convert the UTC time in your frontend template as such:

               <td> 
                   {% load tz %}
                   {% get_current_timezone as tz %}
                   {% timezone tz %}
                       {{ message.log_date | time:'H:i:s' }}
                   {% endtimezone %} 
               </td>
   

or use the template filters concisely:

                <td> 
                    {% load tz %}
                    {{ message.log_date | localtime | time:'H:i:s' }}
                </td>

4. You could check more details in the official doc: Default time zone and current time zone

   When support for time zones is enabled, Django stores datetime information in UTC in the database, uses time-zone-aware datetime objects internally, and translates them to the end user’s time zone in templates and forms.

I write below code to remove the blank value in the array string.

string[] test={"1","","2","","3"};
test= test.Except(new List<string> { string.Empty }).ToArray();

As per my comment on @neves post, I slightly improved this by adding the xlPasteFormats as well as values part so dates go across as dates - I mostly save as CSV for bank statements, so needed dates.

Sub ExportAsCSV()

    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook

    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy

    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
        .PasteSpecial xlPasteValues
        .PasteSpecial xlPasteFormats
    End With

    'Dim Change below to "- 4"  to become compatible with .xls files
    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, Len(CurrentWB.Name) - 5) & ".csv"

    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

No, you don't have to include all of POI's dependencies. Maven's transitive dependency mechanism will take care of that. As noted you just have to express a dependency on the appropriate POI artifact. For example:

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.8-beta4</version>
</dependency>

Edit(UPDATE): I don't know about previous versions but to resolve imports to XSSFWorkbook and other classes in org.apache.poi package you need to add dependency for poi-ooxml too. The dependencies will be:

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>4.1.2</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>4.1.2</version>
</dependency>

You can use the following command to access with your ip.

ng serve --host 0.0.0.0 --disable-host-check

If you are using npm and want to avoid running the command every time, we can add the following line to the package.json file in the scripts section.

"scripts": {
    ...
    "start": "ng serve --host 0.0.0.0 --disable-host-check"
    ...
}

Then you can run you app using the below command to be accessed from the other system in the same network.

npm start

Indeed, as has been mentioned above (and elsewhere on SO), in order to convert the string to a date, you need a specific date of the month. From the as.Date() manual page:

If the date string does not specify the date completely, the returned answer may be system-specific. The most common behaviour is to assume that a missing year, month or day is the current one. If it specifies a date incorrectly, reliable implementations will give an error and the date is reported as NA. Unfortunately some common implementations (such as glibc) are unreliable and guess at the intended meaning.

A simple solution would be to paste the date "01" to each date and use strptime() to indicate it as the first day of that month.

For those seeking a little more background on processing dates and times in R:

In R, times use POSIXct and POSIXlt classes and dates use the Date class.

Dates are stored as the number of days since January 1st, 1970 and times are stored as the number of seconds since January 1st, 1970.

So, for example:

d <- as.Date("1971-01-01")
unclass(d)  # one year after 1970-01-01
# [1] 365

pct <- Sys.time()  # in POSIXct
unclass(pct)  # number of seconds since 1970-01-01
# [1] 1450276559
plt <- as.POSIXlt(pct)
up <- unclass(plt)  # up is now a list containing the components of time
names(up)
# [1] "sec"    "min"    "hour"   "mday"   "mon"    "year"   "wday"   "yday"   "isdst"  "zone"  
# [11] "gmtoff"
up$hour
# [1] 9

To perform operations on dates and times:

plt - as.POSIXlt(d)
# Time difference of 16420.61 days

And to process dates, you can use strptime() (borrowing these examples from the manual page):

strptime("20/2/06 11:16:16.683", "%d/%m/%y %H:%M:%OS")
# [1] "2006-02-20 11:16:16 EST"

# And in vectorized form:
dates <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960")
strptime(dates, "%d%b%Y")
# [1] "1960-01-01 EST" "1960-01-02 EST" "1960-03-31 EST" "1960-07-30 EDT"

I recorded a macro making a hiperlink. This resulted.

ActiveCell.FormulaR1C1 = "=HYPERLINK(""[Workbook.xlsx]Sheet1!A1"",""CLICK HERE"")"

I would assume at the end of the day you want to consume the data in the ArrayNode by iterating it. For that:

Iterator<JsonNode> iterator = datasets.withArray("datasets").elements();
while (iterator.hasNext()) 
        System.out.print(iterator.next().toString() + " "); 

or if you're into streams and lambda functions:

import com.google.common.collect.Streams;
Streams.stream(datasets.withArray("datasets").elements())
    .forEach( item -> System.out.print(item.toString()) )

group - is a reserved word in MySQL, that's why you see such error.

#1064 - You have an error in your SQL syntax; check the manual that corresponds
        to your MySQL server version for the right syntax to use near 'group 
        RENAME TO member' at line 1

You need to wrap table name into backticks:

RENAME TABLE `group` TO `member`;

This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.

var fullEntries = dbContext.tbl_EntryPoint
    .Join(
        dbContext.tbl_Entry,
        entryPoint => entryPoint.EID,
        entry => entry.EID,
        (entryPoint, entry) => new { entryPoint, entry }
    )
    .Join(
        dbContext.tbl_Title,
        combinedEntry => combinedEntry.entry.TID,
        title => title.TID,
        (combinedEntry, title) => new 
        {
            UID = combinedEntry.entry.OwnerUID,
            TID = combinedEntry.entry.TID,
            EID = combinedEntry.entryPoint.EID,
            Title = title.Title
        }
    )
    .Where(fullEntry => fullEntry.UID == user.UID)
    .Take(10);

I would use Joda Time, parse the time as a LocalTime, and then use

time = time.plusMinutes(10);

Short but complete program to demonstrate this:

import org.joda.time.*;
import org.joda.time.format.*;

public class Test {
    public static void main(String[] args) {
        DateTimeFormatter formatter = DateTimeFormat.forPattern("HH:mm");
        LocalTime time = formatter.parseLocalTime("14:10");
        time = time.plusMinutes(10);
        System.out.println(formatter.print(time));
    }       
}

Note that I would definitely use Joda Time instead of java.util.Date/Calendar if you possibly can - it's a much nicer API.

The accepted answer (its image) is wrong, at least now in QT5. Instead you should assign a layout to the root object/widget (pointing to the aforementioned image, it should be the MainWindow instead of centralWidget). Also note that you must have at least one QObject created beneath it for this to work. Do this and your ui will become responsive to window resizing.

Example of prepending in-place:

var A = [7,8,9]_x000D_
var B = [1,2,3]_x000D_
_x000D_
A.unshift(...B)_x000D_
_x000D_
console.log(A) // [1,2,3,7,8,9]

You may also simply write these string extension methods, and put them somewhere in your solution:

using System.Text;

public static class StringExtensions
{
    public static string ReplaceAll(this string original, string toBeReplaced, string newValue)
    {
        if (string.IsNullOrEmpty(original) || string.IsNullOrEmpty(toBeReplaced)) return original;
        if (newValue == null) newValue = string.Empty;
        StringBuilder sb = new StringBuilder();
        foreach (char ch in original)
        {
            if (toBeReplaced.IndexOf(ch) < 0) sb.Append(ch);
            else sb.Append(newValue);
        }
        return sb.ToString();
    }

    public static string ReplaceAll(this string original, string[] toBeReplaced, string newValue)
    {
        if (string.IsNullOrEmpty(original) || toBeReplaced == null || toBeReplaced.Length <= 0) return original;
        if (newValue == null) newValue = string.Empty;
        foreach (string str in toBeReplaced)
            if (!string.IsNullOrEmpty(str))
                original = original.Replace(str, newValue);
        return original;
    }
}

Call them like this:

"ABCDE".ReplaceAll("ACE", "xy");

xyBxyDxy

And this:

"ABCDEF".ReplaceAll(new string[] { "AB", "DE", "EF" }, "xy");

xyCxyF

As far as I can tell, at this point it is not possible to set click_action in the console.

While not a strict answer to how to get the click_action set in the console, you can use curl as an alternative:

curl --header "Authorization: key=<YOUR_KEY_GOES_HERE>" --header Content-Type:"application/json" https://fcm.googleapis.com/fcm/send  -d "{\"to\":\"/topics/news\",\"notification\": {\"title\": \"Click Action Message\",\"text\": \"Sample message\",\"click_action\":\"OPEN_ACTIVITY_1\"}}"

This is an easy way to test click_action mapping. It requires an intent filter like the one specified in the FCM docs:

<intent-filter>_x000D_
  <action android:name="OPEN_ACTIVITY_1" />_x000D_
  <category android:name="android.intent.category.DEFAULT" />_x000D_
</intent-filter>

This also makes use of topics to set the audience. In order for this to work you will need to subscribe to a topic called "news".

FirebaseMessaging.getInstance().subscribeToTopic("news");

Even though it takes several hours to see a newly-created topic in the console, you may still send messages to it through the FCM apis.

Also, keep in mind, this will only work if the app is in the background. If it is in the foreground you will need to implement an extension of FirebaseMessagingService. In the onMessageReceived method, you will need to manually navigate to your click_action target:

    @Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    //This will give you the topic string from curl request (/topics/news)
    Log.d(TAG, "From: " + remoteMessage.getFrom());
    //This will give you the Text property in the curl request(Sample Message): 
    Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
    //This is where you get your click_action 
    Log.d(TAG, "Notification Click Action: " + remoteMessage.getNotification().getClickAction());
    //put code here to navigate based on click_action
}

As I said, at this time I cannot find a way to access notification payload properties through the console, but I thought this work around might be helpful.

I believe that the Roots starter theme has a fantastic function to get the current page title. It is very hackable, covers all bases, and can be easily used with the wp_title hook.

/**
 * Page titles
 */
function roots_title() {
  if (is_home()) {
    if (get_option('page_for_posts', true)) {
      echo get_the_title(get_option('page_for_posts', true));
    } else {
      _e('Latest Posts', 'roots');
    }
  } elseif (is_archive()) {
    $term = get_term_by('slug', get_query_var('term'), get_query_var('taxonomy'));
    if ($term) {
      echo $term->name;
    } elseif (is_post_type_archive()) {
      echo get_queried_object()->labels->name;
    } elseif (is_day()) {
      printf(__('Daily Archives: %s', 'roots'), get_the_date());
    } elseif (is_month()) {
      printf(__('Monthly Archives: %s', 'roots'), get_the_date('F Y'));
    } elseif (is_year()) {
      printf(__('Yearly Archives: %s', 'roots'), get_the_date('Y'));
    } elseif (is_author()) {
      $author = get_queried_object();
      printf(__('Author Archives: %s', 'roots'), $author->display_name);
    } else {
      single_cat_title();
    }
  } elseif (is_search()) {
    printf(__('Search Results for %s', 'roots'), get_search_query());
  } elseif (is_404()) {

The best way to take input of a character in Scanner class is:

Scanner sca=new Scanner(System.in);
System.out.println("enter a character");
char ch=sca.next().charAt(0);

Get-ADGroupMember "Group1" -recursive | Select-Object Name | Export-Csv c:\path\Groups.csv

I got this to work for me... I would assume that you could put "Group1, Group2, etc." or try a wildcard. I did pre-load AD into PowerShell before hand:

Get-Module -ListAvailable | Import-Module

It's an optimization of your algorithm that cuts running time.

While a Greedy Algorithm is usually called naive, because it may run multiple times over the same set of data, Dynamic Programming avoids this pitfall through a deeper understanding of the partial results that must be stored to help build the final solution.

A simple example is traversing a tree or a graph only through the nodes that would contribute with the solution, or putting into a table the solutions that you've found so far so you can avoid traversing the same nodes over and over.

Here's an example of a problem that's suited for dynamic programming, from UVA's online judge: Edit Steps Ladder.

I'm going to make quick briefing of the important part of this problem's analysis, taken from the book Programming Challenges, I suggest you check it out.

Take a good look at that problem, if we define a cost function telling us how far appart two strings are, we have two consider the three natural types of changes:

Substitution - change a single character from pattern "s" to a different character in text "t", such as changing "shot" to "spot".

Insertion - insert a single character into pattern "s" to help it match text "t", such as changing "ago" to "agog".

Deletion - delete a single character from pattern "s" to help it match text "t", such as changing "hour" to "our".

When we set each of this operations to cost one step we define the edit distance between two strings. So how do we compute it?

We can define a recursive algorithm using the observation that the last character in the string must be either matched, substituted, inserted or deleted. Chopping off the characters in the last edit operation leaves a pair operation leaves a pair of smaller strings. Let i and j be the last character of the relevant prefix of and t, respectively. there are three pairs of shorter strings after the last operation, corresponding to the string after a match/substitution, insertion or deletion. If we knew the cost of editing the three pairs of smaller strings, we could decide which option leads to the best solution and choose that option accordingly. We can learn this cost, through the awesome thing that's recursion:

#define MATCH 0 /* enumerated type symbol for match */
#define INSERT 1 /* enumerated type symbol for insert */
#define DELETE 2 /* enumerated type symbol for delete */


int string_compare(char *s, char *t, int i, int j)

{

    int k; /* counter */
    int opt[3]; /* cost of the three options */
    int lowest_cost; /* lowest cost */
    if (i == 0) return(j * indel(’ ’));
    if (j == 0) return(i * indel(’ ’));
    opt[MATCH] = string_compare(s,t,i-1,j-1) +
      match(s[i],t[j]);
    opt[INSERT] = string_compare(s,t,i,j-1) +
      indel(t[j]);
    opt[DELETE] = string_compare(s,t,i-1,j) +
      indel(s[i]);
    lowest_cost = opt[MATCH];
    for (k=INSERT; k<=DELETE; k++)
    if (opt[k] < lowest_cost) lowest_cost = opt[k];
    return( lowest_cost );

}

This algorithm is correct, but is also impossibly slow.

Running on our computer, it takes several seconds to compare two 11-character strings, and the computation disappears into never-never land on anything longer.

Why is the algorithm so slow? It takes exponential time because it recomputes values again and again and again. At every position in the string, the recursion branches three ways, meaning it grows at a rate of at least 3^n – indeed, even faster since most of the calls reduce only one of the two indices, not both of them.

So how can we make the algorithm practical? The important observation is that most of these recursive calls are computing things that have already been computed before. How do we know? Well, there can only be |s| · |t| possible unique recursive calls, since there are only that many distinct (i, j) pairs to serve as the parameters of recursive calls.

By storing the values for each of these (i, j) pairs in a table, we can avoid recomputing them and just look them up as needed.

The table is a two-dimensional matrix m where each of the |s|·|t| cells contains the cost of the optimal solution of this subproblem, as well as a parent pointer explaining how we got to this location:

typedef struct {
int cost; /* cost of reaching this cell */
int parent; /* parent cell */
} cell;

cell m[MAXLEN+1][MAXLEN+1]; /* dynamic programming table */

The dynamic programming version has three differences from the recursive version.

First, it gets its intermediate values using table lookup instead of recursive calls.

**Second,**it updates the parent field of each cell, which will enable us to reconstruct the edit sequence later.

**Third,**Third, it is instrumented using a more general goal cell() function instead of just returning m[|s|][|t|].cost. This will enable us to apply this routine to a wider class of problems.

Here, a very particular analysis of what it takes to gather the most optimal partial results, is what makes the solution a "dynamic" one.

Here's an alternate, full solution to the same problem. It's also a "dynamic" one even though its execution is different. I suggest you check out how efficient the solution is by submitting it to UVA's online judge. I find amazing how such a heavy problem was tackled so efficiently.

May I suggest Node ORM?

https://github.com/dresende/node-orm2

There's documentation on the Readme, supports MySQL, PostgreSQL and SQLite.

MongoDB is available since version 2.1.x (released in July 2013)

UPDATE: This package is no longer maintained, per the project's README. It instead recommends bookshelf and sequelize

To further generalize @Alexander's example, outer is relevant in cases where a function must compute itself on each pair of vector values:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
outer(vars1,vars2,mult_one)

gives:

> outer(vars1, vars2, mult_one)
     [,1] [,2] [,3]
[1,]   10   20   30
[2,]   20   40   60
[3,]   30   60   90

You can do this more simply using plot() instead of plot_date().

First, convert your strings to instances of Python datetime.date:

import datetime as dt

dates = ['01/02/1991','01/03/1991','01/04/1991']
x = [dt.datetime.strptime(d,'%m/%d/%Y').date() for d in dates]
y = range(len(x)) # many thanks to Kyss Tao for setting me straight here

Then plot:

import matplotlib.pyplot as plt
import matplotlib.dates as mdates

plt.gca().xaxis.set_major_formatter(mdates.DateFormatter('%m/%d/%Y'))
plt.gca().xaxis.set_major_locator(mdates.DayLocator())
plt.plot(x,y)
plt.gcf().autofmt_xdate()

Result:

If json object key/name contains dot......! like

var myJson = {"my.name":"vikas","my.age":27}

Than you can access like

myJson["my.name"]
myJson["my.age"]

A shot in the dark, but could it be that you are not allowing installation from unknown sources, and that OI is somehow bypassing that?

There's a difference between additive colors (http://en.wikipedia.org/wiki/Additive_color) and subtractive colors (http://en.wikipedia.org/wiki/Subtractive_color).

With additive colors, the more you add, the brighter the colors become. This is because they are emitting light. This is why the day light is (more or less) white, since the Sun is emitting in almost all the visible wavelength spectrum.

On the other hand, with subtractive colors the more colors you mix, the darker the resulting color. This is because they are reflecting light. This is also why the black colors get hotter quickly, because it absorbs (almost) all light energy and reflects (almost) none.

Specifically to your question, it depends what medium you are working on. Traditionally, additive colors (RGB) are used because the canon for computer graphics was the computer monitor, and since it's emitting light, it makes sense to use the same structure for the graphic card (the colors are shown without conversions). However, if you are used to graphic arts and press, subtractive color model is used (CMYK). In programs such as Photoshop, you can choose to work in CMYK space although it doesn't matter what color model you use: the primary colors of one group are the secondary colors of the second one and viceversa.

P.D.: my father worked at graphic arts, this is why i know this... :-P

Actually you can do it pretty simple, since the list have a ForEach method and since you can pass in Console.WriteLine as a method group. The compiler will then use an implicit conversion to convert the method group to, in this case, an Action<int> and pick the most specific method from the group, in this case Console.WriteLine(int):

  var list = new List<int>(Enumerable.Range(0, 50));

  list.ForEach(Console.WriteLine);

Works with strings too =)

To be utterly pedantic (and I'm not suggesting a change to your answer - just commenting for the sake of interest) Console.WriteLine is a method group. The compiler then uses an implicit conversion from the method group to Action<int>, picking the most specific method (Console.WriteLine(int) in this case).

This is the most complicated scenario I can imagine: I have a PDF file created with Ilustrator and modified with Acrobat to have AcroFields (AcroForm) that I'm going to fill with data with this Java code, the result of that PDF file with the data in the fields is modified adding a Document.

Actually in this case I'm dynamically generating a background that is added to a PDF that is also dynamically generated with a Document with an unknown amount of data or pages.

I'm using JBoss and this code is inside a JSP file (should work in any JSP webserver).

Note: if you are using IExplorer you must submit a HTTP form with POST method to be able to download the file. If not you are going to see the PDF code in the screen. This does not happen in Chrome or Firefox.

<%@ page import="java.io.*, com.lowagie.text.*, com.lowagie.text.pdf.*" %><%

response.setContentType("application/download");
response.setHeader("Content-disposition","attachment;filename=listaPrecios.pdf" );  

// -------- FIRST THE PDF WITH THE INFO ----------
String str = "";
// lots of words
for(int i = 0; i < 800; i++) str += "Hello" + i + " ";
// the document
Document doc = new Document( PageSize.A4, 25, 25, 200, 70 );
ByteArrayOutputStream streamDoc = new ByteArrayOutputStream();
PdfWriter.getInstance( doc, streamDoc );
// lets start filling with info
doc.open();
doc.add(new Paragraph(str));
doc.close();
// the beauty of this is the PDF will have all the pages it needs
PdfReader frente = new PdfReader(streamDoc.toByteArray());
PdfStamper stamperDoc = new PdfStamper( frente, response.getOutputStream());

// -------- THE BACKGROUND PDF FILE -------
// in JBoss the file has to be in webinf/classes to be readed this way
PdfReader fondo = new PdfReader("listaPrecios.pdf");
ByteArrayOutputStream streamFondo = new ByteArrayOutputStream();
PdfStamper stamperFondo = new PdfStamper( fondo, streamFondo);
// the acroform
AcroFields form = stamperFondo.getAcroFields();
// the fields 
form.setField("nombre","Avicultura");
form.setField("descripcion","Esto describe para que sirve la lista ");
stamperFondo.setFormFlattening(true);
stamperFondo.close();
// our background is ready
PdfReader fondoEstampado = new PdfReader( streamFondo.toByteArray() );

// ---- ADDING THE BACKGROUND TO EACH DATA PAGE ---------
PdfImportedPage pagina = stamperDoc.getImportedPage(fondoEstampado,1);
int n = frente.getNumberOfPages();
PdfContentByte background;
for (int i = 1; i <= n; i++) {
    background = stamperDoc.getUnderContent(i);
    background.addTemplate(pagina, 0, 0);
}
// after this everithing will be written in response.getOutputStream()
stamperDoc.close(); 
%>

There is another solution much simpler, and solves your problem. It depends the amount of text you want to add.

// read the file
PdfReader fondo = new PdfReader("listaPrecios.pdf");
PdfStamper stamper = new PdfStamper( fondo, response.getOutputStream());
PdfContentByte content = stamper.getOverContent(1);
// add text
ColumnText ct = new ColumnText( content );
// this are the coordinates where you want to add text
// if the text does not fit inside it will be cropped
ct.setSimpleColumn(50,500,500,50);
ct.setText(new Phrase(str, titulo1));
ct.go();

Well, I would like to add my 2 cents here.

I'm using shared webhosting and I tackled this problem many times, tried to resolve it on my own but to no avail. Finally I managed to resolve it through checking various web sources and contacting my hosting service provider. My questions were "How can I change php value memory_limit in shared webhosting?", "How can I change php value upload_max_filesize in shared webhosting?", "How can I change php value max_input_vars in shared webhosting?", "How can I change php value max_execution_time in shared webhosting?", "How can I change php value max_input_time in shared webhosting?" and many more by configuring or changing php.ini or .htaccess file. I tried to change them but problems arose. Finally I contacted my hosting provider, and it turns out that I set my php to native, they changed it to php 5.6, here is their answer:

"Your PHP was set to 'native' mode which means you can't override those values. I've changed you to just '5.6' so you should be good to go."

After that I connected my website through ftp Filezilla, also don't forget to make both your ftp service to show hidden files, and your local computer to do so, because .htaccess file was hidden in my local laptop and in my website. It was available in public_html folder, I just downloaded it and added the following codes to the end of the file and then uploaded it back to the server:

php_value memory_limit 256M
php_value post_max_size 256M
php_value upload_max_filesize 64M
php_value max_input_vars 1800
php_value max_execution_time 300
php_value max_input_time 300

Everything is working properly for the time being, if any of you overcome with some problems please write here and warn me so that I can change the above-shown codes. By the way, I also upload some pictures which shows the change.

One more thing I almost forgot to mention ZipArchive installation on your shared webhosting service, I managed that requirement to tick by just going to php settings through my cpanel, click on php selector extensions and then tick zip section, that's all.

Thanks.

PS: I'm open to good practices, and if you see any bad practice here please let me know, I'll try to change them. Thanks.

Use 'a', 'a' means append. Anything written to a file opened with 'a' attribute is written at the end of the file.

with open('file.txt', 'a') as file:
    file.write('input')

I have a similar problem. I open an error dialog when validation fails and it grabs the focus, just like Flugan shows it in his answer. The problem is that even if no element inside the dialog is tabbable, the dialog itself is still focused. Here is the original unminified code from jquery-ui-1.8.23\js\jquery.ui.dialog.js:

// set focus to the first tabbable element in the content area or the first button
// if there are no tabbable elements, set focus on the dialog itself
$(self.element.find(':tabbable').get().concat(
  uiDialog.find('.ui-dialog-buttonpane :tabbable').get().concat(
    uiDialog.get()))).eq(0).focus();

The comment is theirs!

This is really bad for me for several reasons. The most annoying thing is that the first reaction of the user is to hit the backspace to delete the last character, but instead (s)he is prompted to leave the page, because the backspace is hit outside an input control.

I found that the following workaround works pretty good for me:

jqueryFocus = $.fn.focus;
$.fn.focus = function (delay, fn) {
  jqueryFocus.apply(this.filter(':not(.ui-dialog)'), arguments);
};

If you want the result plus the number of rows returned do something like this. Using PHP.

$query = "SELECT * FROM Employee";
$result = mysql_query($query);
echo "There are ".mysql_num_rows($result)." Employee(s).";

Took me some time, but I finally manage do make an app that does just that. Check out the google code page if you're interested: http://code.google.com/p/spydroid-ipcamera/ I added loads of comments in my code (mainly, look at CameraStreamer.java), so it should be pretty self-explanatory. The hard part was actually to understand the RFC 3984 and implement a proper algorithm for the packetization process. (This algorithm actually turns the mpeg4/h.264 stream produced by the MediaRecorder into a nice rtp stream, according to the rfc)

Not necessarily better than the accepted answer, but it's another approach not yet listed.

You don't necessarily have to choose between the two paradigms. You can write software with an OO architecture using many functional concepts. FP and OOP are orthogonal in nature.

Take for example C#. You could say it's mostly OOP, but there are many FP concepts and constructs. If you consider Linq, the most important constructs that permit Linq to exist are functional in nature: lambda expressions.

Another example, F#. You could say it's mostly FP, but there are many OOP concepts and constructs available. You can define classes, abstract classes, interfaces, deal with inheritance. You can even use mutability when it makes your code clearer or when it dramatically increases performance.

Many modern languages are multi-paradigm.

Recommended readings

As I'm in the same boat (OOP background, learning FP), I'd suggest you some readings I've really appreciated:

• Functional Programming for Everyday .NET Development, by Jeremy Miller. A great article (although poorly formatted) showing many techniques and practical, real-world examples of FP on C#.

• Real-World Functional Programming, by Tomas Petricek. A great book that deals mainly with FP concepts, trying to explain what they are, when they should be used. There are many examples in both F# and C#. Also, Petricek's blog is a great source of information.

You should use double slash:

var regex = new RegExp("\\?", "g");

Why? because in JavaScript the \ is also used to escape characters in strings, so: "\?" becomes: "?"

And "\\?", becomes "\?"

      $name = $_POST['name'];

java.time

Since Java 1.8, you can achieve this without an extra library by using the java.time classes. See Tutorial.

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MMM-dd");
formatter = formatter.withLocale( putAppropriateLocaleHere );  // Locale specifies human language for translating, and cultural norms for lowercase/uppercase and abbreviations and such. Example: Locale.US or Locale.CANADA_FRENCH
LocalDate date = LocalDate.parse("2005-nov-12", formatter);

The syntax is nearly the same though.

For different types of arguments, there is 3-dots :

public void foo(Object... x) {
    String myVar1  = x.length > 0 ? (String)x[0]  : "Hello";
    int myVar2     = x.length > 1 ? Integer.parseInt((String) x[1]) : 888;
} 

Then call it

foo("Hii"); 
foo("Hii", 146); 

for security, use like this:
if (!(x[0] instanceof String)) { throw new IllegalArgumentException("..."); }

The main drawback of this approach is that if optional parameters are of different types you lose static type checking. Please, see more variations .

\w is not a word boundary, it matches any word character, including underscores: [a-zA-Z0-9_]. \b is a word boundary, that is, it matches the position between a word and a non-alphanumeric character: \W or [^\w].

myBrush.GradientStops.Add(new GradientStop(Colors.Orange, 0.5));
myBrush.GradientStops.Add(new GradientStop(Colors.Red, 1.0));
TextBox.Background = myBrush;

• The first danger lies in reload(sys).

  When you reload a module, you actually get two copies of the module in your runtime. The old module is a Python object like everything else, and stays alive as long as there are references to it. So, half of the objects will be pointing to the old module, and half to the new one. When you make some change, you will never see it coming when some random object doesn't see the change:

  (This is IPython shell)
  
  In [1]: import sys
  
  In [2]: sys.stdout
  Out[2]: <colorama.ansitowin32.StreamWrapper at 0x3a2aac8>
  
  In [3]: reload(sys)
  <module 'sys' (built-in)>
  
  In [4]: sys.stdout
  Out[4]: <open file '<stdout>', mode 'w' at 0x00000000022E20C0>
  
  In [11]: import IPython.terminal
  
  In [14]: IPython.terminal.interactiveshell.sys.stdout
  Out[14]: <colorama.ansitowin32.StreamWrapper at 0x3a9aac8>
  

• Now, sys.setdefaultencoding() proper

  All that it affects is implicit conversion str<->unicode. Now, utf-8 is the sanest encoding on the planet (backward-compatible with ASCII and all), the conversion now "just works", what could possibly go wrong?

  Well, anything. And that is the danger.

  • There may be some code that relies on the UnicodeError being thrown for non-ASCII input, or does the transcoding with an error handler, which now produces an unexpected result. And since all code is tested with the default setting, you're strictly on "unsupported" territory here, and no-one gives you guarantees about how their code will behave.
  • The transcoding may produce unexpected or unusable results if not everything on the system uses UTF-8 because Python 2 actually has multiple independent "default string encodings". (Remember, a program must work for the customer, on the customer's equipment.)
    • Again, the worst thing is you will never know that because the conversion is implicit -- you don't really know when and where it happens. (Python Zen, koan 2 ahoy!) You will never know why (and if) your code works on one system and breaks on another. (Or better yet, works in IDE and breaks in console.)

I assume due diligence here that you confirmed the CPU is actually consumed by SQL process (perfmon Process category counters would confirm this). Normally for such cases you take a sample of the relevant performance counters and you compare them with a baseline that you established in normal load operating conditions. Once you resolve this problem I recommend you do establish such a baseline for future comparisons.

You can find exactly where is SQL spending every single CPU cycle. But knowing where to look takes a lot of know how and experience. Is is SQL 2005/2008 or 2000 ? Fortunately for 2005 and newer there are a couple of off the shelf solutions. You already got a couple good pointer here with John Samson's answer. I'd like to add a recommendation to download and install the SQL Server Performance Dashboard Reports. Some of those reports include top queries by time or by I/O, most used data files and so on and you can quickly get a feel where the problem is. The output is both numerical and graphical so it is more usefull for a beginner.

I would also recommend using Adam's Who is Active script, although that is a bit more advanced.

And last but not least I recommend you download and read the MS SQL Customer Advisory Team white paper on performance analysis: SQL 2005 Waits and Queues.

My recommendation is also to look at I/O. If you added a load to the server that trashes the buffer pool (ie. it needs so much data that it evicts the cached data pages from memory) the result would be a significant increase in CPU (sounds surprising, but is true). The culprit is usually a new query that scans a big table end-to-end.

REST concepts are referred to as resources. A representation of a resource must be stateless. It is represented via some media type. Some examples of media types include XML, JSON, and RDF. Resources are manipulated by components. Components request and manipulate resources via a standard uniform interface. In the case of HTTP, this interface consists of standard HTTP ops e.g. GET, PUT, POST, DELETE.

REST is typically used over HTTP, primarily due to the simplicity of HTTP and its very natural mapping to RESTful principles. REST however is not tied to any specific protocol.

Fundamental REST Principles

Client-Server Communication

Client-server architectures have a very distinct separation of concerns. All applications built in the RESTful style must also be client-server in principle.

Stateless

Each client request to the server requires that its state be fully represented. The server must be able to completely understand the client request without using any server context or server session state. It follows that all state must be kept on the client. We will discuss stateless representation in more detail later.

Cacheable

Cache constraints may be used, thus enabling response data to to be marked as cacheable or not-cachable. Any data marked as cacheable may be reused as the response to the same subsequent request.

Uniform Interface

All components must interact through a single uniform interface. Because all component interaction occurs via this interface, interaction with different services is very simple. The interface is the same! This also means that implementation changes can be made in isolation. Such changes, will not affect fundamental component interaction because the uniform interface is always unchanged. One disadvantage is that you are stuck with the interface. If an optimization could be provided to a specific service by changing the interface, you are out of luck as REST prohibits this. On the bright side, however, REST is optimized for the web, hence incredible popularity of REST over HTTP!

The above concepts represent defining characteristics of REST and differentiate the REST architecture from other architectures like web services. It is useful to note that a REST service is a web service, but a web service is not necessarily a REST service.

See this blog post on REST Design Principals for more details on REST and the above principles.

This should do what you want:

import datetime
yesterday = datetime.datetime.now() - datetime.timedelta(days = 1)
print yesterday.strftime("%m%d%y")

Best way is putting a random value in a new column just for that purpose, and using something like this (pseude code + SQL):

randomNo = random()
execSql("SELECT TOP 1 * FROM MyTable WHERE MyTable.Randomness > $randomNo")

This is the solution employed by the MediaWiki code. Of course, there is some bias against smaller values, but they found that it was sufficient to wrap the random value around to zero when no rows are fetched.

newid() solution may require a full table scan so that each row can be assigned a new guid, which will be much less performant.

rand() solution may not work at all (i.e. with MSSQL) because the function will be evaluated just once, and every row will be assigned the same "random" number.

While I agree with what's mentioned in the answers below, suggesting that this is a very bad design for a Userform unless copious amounts of error checks are included...

to accomplish what you need to do, with minimal changes to your code, there are two approaches.

1. Use KeyUp() event instead of Change event for the textbox. Here is an example:

   Private Sub TextBox2_KeyUp(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
   
       Dim TextStr As String
       TextStr = TextBox2.Text
   
       If KeyCode <> 8 Then ' i.e. not a backspace
   
           If (Len(TextStr) = 2 Or Len(TextStr) = 5) Then
               TextStr = TextStr & "/"
           End If
   
       End If
       TextBox2.Text = TextStr
   End Sub
   

2. Alternately, if you need to use the Change() event, use the following code. This alters the behavior so the user keeps entering the numbers, as

   12072003
   

while the result as he's typing appears as

    12/07/2003

But the '/' character appears only once the first character of the DD i.e. 0 of 07 is entered. Not ideal, but will still handle backspaces.

    Private Sub TextBox1_Change()
        Dim TextStr As String

        TextStr = TextBox1.Text

        If (Len(TextStr) = 3 And Mid(TextStr, 3, 1) <> "/") Then
            TextStr = Left(TextStr, 2) & "/" & Right(TextStr, 1)
        ElseIf (Len(TextStr) = 6 And Mid(TextStr, 6, 1) <> "/") Then
            TextStr = Left(TextStr, 5) & "/" & Right(TextStr, 1)
        End If

        TextBox1.Text = TextStr
    End Sub

the cross browser code is:

$(window).scrollTop(300); 

it is without animation but works everywhere

The first question is what are your needs? UTF-8 encoding is a pretty good compromise between taking text created with a cheap editor and support for a wide variety of languages. In regards to the browser identifying the encoding, the response (from the web server) should tell the browser the encoding. Still most browsers will attempt to guess, because this is either missing or wrong in so many cases. They guess by reading some amount of the result stream to see if there is a character that does not fit in the default encoding. Currently all browser(? I did not check this, but it is pretty close to true) use utf-8 as the default.

So use utf-8 unless you have a compelling reason to use one of the many other encoding schemes.

Updated answer from Stephen Groom for Swift 3

let email = "[email protected]"
let url = URL(string: "mailto:\(email)")
UIApplication.shared.openURL(url!)

Similar issue, although I'm sure only on surface. Anyway, it may help someone: what I did (FWIW, in SourceTree): stashed the uncommitted file, then did a hard reset.

The language spec mentions comparison operators' behaviors:

comparison operators

In any comparison, the first operand must be assignable to the type of the second operand, or vice versa.

Assignability

A value x is assignable to a variable of type T ("x is assignable to T") in any of these cases:

• x's type is identical to T.
• x's type V and T have identical underlying types and at least one of V or T is not a named type.
• T is an interface type and x implements T.
• x is a bidirectional channel value, T is a channel type, x's type V and T have identical element types, and at least one of V or T is not a named type.
• x is the predeclared identifier nil and T is a pointer, function, slice, map, channel, or interface type.
• x is an untyped constant representable by a value of type T.

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

A DRY'r Way of Doing It

And, generally, a neat trick to remove the quotes.

@mixin box-shadow($top, $left, $blur, $color, $inset:"") {
  -webkit-box-shadow: $top $left $blur $color #{$inset};
  -moz-box-shadow:    $top $left $blur $color #{$inset};
  box-shadow:         $top $left $blur $color #{$inset};
}

SASS Version 3+, you can use unquote():

@mixin box-shadow($top, $left, $blur, $color, $inset:"") {
  -webkit-box-shadow: $top $left $blur $color unquote($inset);
  -moz-box-shadow:    $top $left $blur $color unquote($inset);
  box-shadow:         $top $left $blur $color unquote($inset);
} 

Picked this up over here: pass a list to a mixin as a single argument with SASS

You can find documentation here.

Based on your requirement you can try according option.

to ellipsize, a neologism, means to shorten text using an ellipsis, i.e. three dots ... or more commonly ligature …, to stand in for the omitted bits.

Say original value pf text view is aaabbbccc and its fitting inside the view

start's output will be : ...bccc

end's output will be : aaab...

middle's output will be : aa...cc

marquee's output will be : aaabbbccc auto sliding from right to left

You can use like this

${fn:length(numList)}

You can receive returning results like that: AsyncTask class

@Override
protected Boolean doInBackground(Void... params) {
    if (host.isEmpty() || dbName.isEmpty() || user.isEmpty() || pass.isEmpty() || port.isEmpty()) {
        try {
            throw new SQLException("Database credentials missing");
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    try {
        Class.forName("org.postgresql.Driver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    try {
        this.conn = DriverManager.getConnection(this.host + ':' + this.port + '/' + this.dbName, this.user, this.pass);
    } catch (SQLException e) {
        e.printStackTrace();
    }

    return true;
}

receiving class:

_store.execute();
boolean result =_store.get();

Hoping it will help.

This should give you a list of all the tables in your database

SELECT Distinct TABLE_NAME FROM information_schema.TABLES

So you can use it similar to your database check.

If NOT EXISTS(SELECT Distinct TABLE_NAME FROM information_schema.TABLES Where TABLE_NAME = 'Your_Table')
BEGIN
    --CREATE TABLE Your_Table
END
GO

You can use the sprintf method, however the arg method is preferred as it supports unicode.

QString str;
str.sprintf("%s %d", "string", 213);

PreparedStatement

You should definitely use a PreparedStatement. (Tutorial)

That way you can invoke:

pstmt.setDate( 1, aDate );

The JDBC driver will do date-time handling appropriate for your particular database.

Also, a PreparedStatement stops any SQL injection hacking attempts – very important! (humor)

It should look like this:

SimpleDateFormat format = new SimpleDateFormat( "MM/dd/yyyy" );  // United States style of format.
java.util.Date myDate = format.parse( "10/10/2009" );  // Notice the ".util." of package name.

PreparedStatement pstmt = connection.prepareStatement(
"INSERT INTO USERS ( USER_ID, FIRST_NAME, LAST_NAME, SEX, DATE ) " +
" values (?, ?, ?, ?, ? )");

pstmt.setString( 1, userId );
pstmt.setString( 3, myUser.getLastName() ); 
pstmt.setString( 2, myUser.getFirstName() ); // please use "getFir…" instead of "GetFir…", per Java conventions.
pstmt.setString( 4, myUser.getSex() );
java.sql.Date sqlDate = new java.sql.Date( myDate.getTime() ); // Notice the ".sql." (not "util") in package name.
pstmt.setDate( 5, sqlDate ); 

And that's it, the JDBC driver will create the right SQL syntax for you.

Retrieving

When retrieving a Date object, you can use a SimpleDateFormat to create a formatted string representation of the date-time value.

Here is one quick example line, but search StackOverflow for many more.

String s = new SimpleDateFormat("dd/MM/yyyy").format( aDate );
