This one works pretty well with git-2.18.2 and can be launched from outside git target repository:

basename -s .git $(git --git-dir=/<project-path>/.git remote get-url origin)

For paths greater than 260:
you can use:

Get-ChildItem | Where-Object {$_.FullName.Length -gt 260}

Example on 14 chars:
To view the paths lengths:

Get-ChildItem | Select-Object -Property FullName, @{Name="FullNameLength";Expression={($_.FullName.Length)}

Get paths greater than 14:

Get-ChildItem | Where-Object {$_.FullName.Length -gt 14}  

Screenshot:

For filenames greater than 10:

Get-ChildItem | Where-Object {$_.PSChildName.Length -gt 10}

Sorry but I don't understand why too many people even think a string was something that could be evaluated. You must change your mindset, really. Forget all connections between strings on one side and expressions, calls, evaluation on the other side.

The (possibly) only connection is via parse(text = ....) and all good R programmers should know that this is rarely an efficient or safe means to construct expressions (or calls). Rather learn more about substitute(), quote(), and possibly the power of using do.call(substitute, ......).

# If the answer is parse() you should usually rethink the question.
#    -- Thomas Lumley
#       R-help (February 2005)

Dec.2017: Ok, here is an example (in comments, there's no nice formatting):

q5 <- quote(5+5)
str(q5)
# language 5 + 5

e5 <- expression(5+5)
str(e5)
# expression(5 + 5)

and if you get more experienced you'll learn that q5 is a "call" whereas e5 is an "expression", and even that e5[[1]] is identical to q5:

identical(q5, e5[[1]])
# [1] TRUE

Here's a modified version of Fred Foo's answer for Python 2. In the original response, only the deepest level of nesting is output. If you output the keys as lists, you can keep the keys for all levels, although to reference them you need to reference a list of lists.

Here's the function:

def NestIter(nested):
    for key, value in nested.iteritems():
        if isinstance(value, collections.Mapping):
            for inner_key, inner_value in NestIter(value):
                yield [key, inner_key], inner_value
        else:
            yield [key],value

To reference the keys:

for keys, vals in mynested: 
    print(mynested[keys[0]][keys[1][0]][keys[1][1][0]])

for a three-level dictionary.

You need to know the number of levels before to access multiple keys and the number of levels should be constant (it may be possible to add a small bit of script to check the number of nesting levels when iterating through values, but I haven't yet looked at this).

Lucas's answer about core dumps is good. In my .cshrc I have:

alias core 'ls -lt core; echo where | gdb -core=core -silent; echo "\n"'

to display the backtrace by entering 'core'. And the date stamp, to ensure I am looking at the right file :(.

Added: If there is a stack corruption bug, then the backtrace applied to the core dump is often garbage. In this case, running the program within gdb can give better results, as per the accepted answer (assuming the fault is easily reproducible). And also beware of multiple processes dumping core simultaneously; some OS's add the PID to the name of the core file.

This is the working solution to this problem I found.

sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update

For anyone running into a problem where build automatically is unchecked but the project is still building. Make sure your project isn't deployed to the server in the server tab and told to stay synchronous.

To download ISIN code data the only place I see this is on the ISIN organizations website, www.isin.org. try http://isin.org, they should have a function where you can easily download.

I was getting the error on an iOS 7 device when I was using Xcode 6.2 beta.

Switching back from Xcode 6.2 beta to 6.1.1 fixed the issue, at least on an iOS 7 device.

server.session.timeout in the application.properties file is now deprecated. The correct setting is:

server.servlet.session.timeout=60s

Also note that Tomcat will not allow you to set the timeout any less than 60 seconds. For details about that minimum setting see https://github.com/spring-projects/spring-boot/issues/7383.

A few ways:

-- Do the comparison, OR'd with a check on the @Country=0 case
WHERE (a.Country = @Country OR @Country = 0)

-- compare the Country field to itself
WHERE a.Country = CASE WHEN @Country > 0 THEN @Country ELSE a.Country END

Or, use a dynamically generated statement and only add in the Country condition if appropriate. This should be most efficient in the sense that you only execute a query with the conditions that actually need to apply and can result in a better execution plan if supporting indices are in place. You would need to use parameterised SQL to prevent against SQL injection.

You have encoding problem with your sourcecode file. It is maybe ISO-8859-1 encoded, but the compiler was set to use UTF-8. This will results in errors when using characters, which will not have the same bytes representation in UTF-8 and ISO-8859-1. This will happen to all characters which are not part of ASCII, for example ¬ NOT SIGN.

You can simulate this with the following program. It just uses your line of source code and generates a ISO-8859-1 byte array and decode this "wrong" with UTF-8 encoding. You can see at which position the line gets corrupted. I added 2 spaces at your source code to fit position 74 to fit this to ¬ NOT SIGN, which is the only character, which will generate different bytes in ISO-8859-1 encoding and UTF-8 encoding. I guess this will match indentation with the real source file.

 String reg = "      String reg = \"^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[~#;:?/@&!\"'%*=¬.,-])(?=[^\\s]+$).{8,24}$\";";
 String corrupt=new String(reg.getBytes("ISO-8859-1"),"UTF-8");
 System.out.println(corrupt+": "+corrupt.charAt(74));
 System.out.println(reg+": "+reg.charAt(74));     

which results in the following output (messed up because of markup):

String reg = "^(?=.[0-9])(?=.[a-z])(?=.[A-Z])(?=.[~#;:?/@&!"'%*=?.,-])(?=[^\s]+$).{8,24}$";: ?

String reg = "^(?=.[0-9])(?=.[a-z])(?=.[A-Z])(?=.[~#;:?/@&!"'%*=¬.,-])(?=[^\s]+$).{8,24}$";: ¬

See "live" at https://ideone.com/ShZnB

To fix this, save the source files with UTF-8 encoding.

If you want to initialize an array in a constructor, you can't use those array initializer like.

data= {10,20,30,40,50,60,71,80,90,91};

Just change it to

data = new int[] {10,20,30,40,50,60,71,80,90,91};

You don't have to specify the size with data[10] = new int[] { 10,...,91} Just declare the property / field with int[] data; and initialize it like above. The corrected version of your code would look like the following:

public class Array {

    int[] data;

    public Array() {
        data = new int[] {10,20,30,40,50,60,71,80,90,91};
    }

}

As you see the bracket are empty. There isn't any need to tell the size between the brackets, because the initialization and its size are specified by the count of the elements between the curly brackets.

I added the following to the manifest for that activity

android:configChanges="keyboardHidden|orientation|screenLayout"

I have spent about a week solving this problem. Most of the answers are sort of magic (no logical purposes for these algorithms) and they were not useful for me. I found this error in Xcode console:

ERROR ITMS-90174: "Missing Provisioning Profile - iOS Apps must contain a provisioning profile in a file named embedded.mobileprovision."

And found this answer solving this issue. The case is to switch Xcode Build system to the Legacy one.

I was deploying my Ionic app.

Slightly different option usually works for me:

1. "mvn eclipse:eclipse" for this project in the command line.
2. "Refresh/F5" this project in eclipse.

That's all, no need to re-import but need to have the terminal window handy.

In Swift 2,Apple introduced a new feature called API availability checking, which might be a replacement for respondsToSelector: method.The following code snippet comparison is copied from the WWDC2015 Session 106 What's New in Swift which I thought might help you,please check it out if you need to know more.

The Old Approach:

@IBOutlet var dropButton: NSButton!
override func awakeFromNib() {
    if dropButton.respondsToSelector("setSpringLoaded:") {
        dropButton.springLoaded = true
    }
}

The Better Approach:

@IBOutlet var dropButton: NSButton!
override func awakeFromNib() {
    if #available(OSX 10.10.3, *) {
        dropButton.springLoaded = true
    }
}

Above solutions should solve your problem. If these do not, make sure you update your Android sdk using SDK manager and install the latest lib project and then repeat the above steps again.

Here's the problem with family trees: they are not trees. They are directed acyclic graphs or DAGs. If I understand the principles of the biology of human reproduction correctly, there will not be any cycles.

As far as I know, even the Christians accept marriages (and thus children) between cousins, which will turn the family tree into a family DAG.

The moral of the story is: choose the right data structures.

You should take a look at various javascript libraries, they should be able to help you out:

• mootools
• jQuery
• Dojo Toolkit
• prototype

All of them have tutorials, and fade in/fade out is a basic usage.

For e.g. in jQuery:

var $img = $("img"), i = 0, speed = 200;
window.setInterval(function() {
  $img.fadeOut(speed, function() {
    $img.attr("src", images[(++i % images.length)]);
    $img.fadeIn(speed);
  });
}, 30000);

Using NetBeans 7.0:

If you fix imports before R.java has been generated for your project (before building it the first time) it will add the line:

import android.R;

which will override the local R.java that you are trying to reference.

Deleting that line resolved the errors for me.

As hinted at in yatima2975's answer, there is an additional difference:

substr() accepts a negative starting position as an offset from the end of the string. substring() does not.

From MDN:

If start is negative, substr() uses it as a character index from the end of the string.

So to sum up the functional differences:

substring(begin-offset, end-offset-exclusive) where begin-offset is 0 or greater

substr(begin-offset, length) where begin-offset may also be negative

$('.page-address-edit').addClass('test1 test2 test3');

Ref- jQuery

First, we choose stable (not static) data columns to form a Primary Key, precisely because updating Keys in a Relational database (in which the references are by Key) is something we wish to avoid.

1. For this issue, it doesn't matter if the Key is a Relational Key ("made up from the data"), and thus has Relational Integrity, Power, and Speed, or if the "key" is a Record ID, with none of that Relational Integrity, Power, and Speed. The effect is the same.

2. I state this because there are many posts by the clueless ones, who suggest that this is the exact reason that Record IDs are somehow better than Relational Keys.

3. The point is, the Key or Record ID is migrated to wherever a reference is required.

Second, if you have to change the value of the Key or Record ID, well, you have to change it. Here is the OLTP Standard-compliant method. Note that the high-end vendors do not allow "cascade update".

• Write a proc. Foo_UpdateCascade_tr @ID, where Foo is the table name

• Begin a Transaction

• First INSERT-SELECT a new row in the parent table, from the old row, with the new Key or RID value

• Second, for all child tables, working top to bottom, INSERT-SELECT the new rows, from the old rows, with the new Key or RID value

• Third, DELETE the rows in the child tables that have the old Key or RID value, working bottom to top

• Last, DELETE the row in the parent table that has the old Key or RID value

• Commit the Transaction

Re the Other Answers

The other answers are incorrect.

• Disabling constraints and then enabling them, after UPDATing the required rows (parent plus all children) is not something that a person would do in an online production environment, if they wish to remain employed. That advice is good for single-user databases.

• The need to change the value of a Key or RID is not indicative of a design flaw. It is an ordinary need. That is mitigated by choosing stable (not static) Keys. It can be mitigated, but it cannot be eliminated.

• A surrogate substituting a natural Key, will not make any difference. In the example you have given, the "key" is a surrogate. And it needs to be updated.

  • Please, just surrogate, there is no such thing as a "surrogate key", because each word contradicts the other. Either it is a Key (made up from the data) xor it isn't. A surrogate is not made up from the data, it is explicitly non-data. It has none of the properties of a Key.

• There is nothing "tricky" about cascading all the required changes. Refer to the steps given above.

• There is nothing that can be prevented re the universe changing. It changes. Deal with it. And since the database is a collection of facts about the universe, when the universe changes, the database will have to change. That is life in the big city, it is not for new players.

• People getting married and hedgehogs getting buried are not a problem (despite such examples being used to suggest that it is a problem). Because we do not use Names as Keys. We use small, stable Identifiers, such as are used to Identify the data in the universe.

  • Names, descriptions, etc, exist once, in one row. Keys exist wherever they have been migrated. And if the "key" is a RID, then the RID too, exists wherever it has been migrated.

• Don't update the PK! is the second-most hilarious thing I have read in a while. Add a new column is the most.

well, you can very quickly test the click dispatch via jQuery like so

$('#link-id').click();

If you're still having problem with click respecting the target, you can always do this

$('#link-id').click( function( event, anchor )
{
  window.open( anchor.href, anchor.target, '' );
  event.preventDefault();
  return false;
});

I am now able to successfully build. Not sure exactly which step "fixed" things, but this was the sequence:

• Tried automatic signing again. No go, so reverted to manual.
• After reverting, I had no Eligible Profiles, all were ineligible. Strange.
• I created a new certificate and profile, imported both. This too was "ineligible".
• Removed the iOS platform and re-added it. I had tried this previously without luck.
• After doing this, Xcode on its own defaulted to automatic signing. And this worked! Success!

While I am not sure exactly which parts were necessary, I think the previous certificates were the problem. I hate Xcode :(

Thanks for help.

You're comparing strings. JavaScript compares the ASCII code for each character of the string.

To see why you get false, look at the charCodes:

"1300".charCodeAt(0);
49
"999".charCodeAt(0);
57

The comparison is false because, when comparing the strings, the character codes for 1 is not greater than that of 9.

The fix is to treat the strings as numbers. You can use a number of methods:

parseInt(string, radix)
parseInt("1300", 10);
> 1300 - notice the lack of quotes


+"1300"
> 1300


Number("1300")
> 1300

you can also get json by using requests as below:

import requests

r = requests.get('http://yoursite.com/your-json-pfile.json')
json_response = r.json()

Final Working Solution for me (Highlighted the tages in the sample code):

1. add the xmlns:tools line in the manifest tag
2. add tools:replace in the application tag

Example:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="pagination.yoga.com.tamiltv"
    **xmlns:tools="http://schemas.android.com/tools"**
    >

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        **tools:replace="android:icon,android:theme"**
        >

public class prime{
    public static void main(String ar[])
    {
      int count;
      int no=0;
      for(int i=0;i<1000;i++){
        count=0;
        for(int j=1;j<=i;j++){

        if(i%j==0){
          count++;
         }
        }
        if(count==2){
          no++;
          if(no==Integer.parseInt(ar[0])){
            System.out.println(no+"\t"+i+"\t") ;
          }
        }
      }
    }
}

Try not to do DOM manipulation by referring the DOM directly, it will have lot of performance issue, also event handling becomes more tricky when we try to access DOM directly, instead use data and directives to manipulate the DOM.

This will give you more control over the manipulation, also you will be able to manage functionalities in the modular format.

As other answers have noted, you cannot change an existing tuple, but you can always create a new tuple (which may take some or all items from existing tuples and/or other sources).

For example, if all the items of interest are in scalar variables and you know the names of those variables:

def maketuple(variables, names):
  return tuple(variables[n] for n in names)

to be used, e.g, as in this example:

def example():
  x = 23
  y = 45
  z = 67
  return maketuple(vars(), 'x y z'.split())

of course this one case would be more simply expressed as (x, y, z) (or even foregoing the names altogether, (23, 45, 67)), but the maketuple approach might be useful in some more complicated cases (e.g. where the names to use are also determined dynamically and appended to a list during the computation).

In JavaScript when you create any object through a constructor call like below

step 1 : create a function say Person..

function Person(name){
this.name=name;
}
person.prototype.print=function(){
console.log(this.name);
}

step 2 : create an instance for this function..

var obj=new Person('venkat')

//above line will instantiate this function(Person) and return a brand new object called Person {name:'venkat'}

if you don't want to instantiate this function and call at same time.we can also do like below..

var Person = {
  init: function(name){
    this.name=name;
  },
  print: function(){
    console.log(this.name);
  }
};
var obj=Object.create(Person);
obj.init('venkat');
obj.print();

in the above method init will help in instantiating the object properties. basically init is like a constructor call on your class.

I recommend PyInstaller, a simple python script can be converted to an exe with the following commands:

utils/Makespec.py [--onefile] oldlogs.py

which creates a yourprogram.spec file which is a configuration for building the final exe. Next command builds the exe from the configuration file:

utils/Build.py oldlogs.spec

If your are using Swift version >= 3.0 there are some code updates you have to apply as others have already said. Just don't forget to call super:

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {

   super.viewWillTransition(to: size, with: coordinator)

   // YOUR CODE OR FUNCTIONS CALL HERE

}

If you are thinking to use a StackView for your images be aware you can do something like the following:

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {

   super.viewWillTransition(to: size, with: coordinator)

   if UIDevice.current.orientation.isLandscape {

      stackView.axis = .horizontal

   } else {

      stackView.axis = .vertical

   } // else

}

If your are using Interface Builder don't forget to select the custom class for this UIStackView object, in the Identity Inspector section at the right panel. Then just create (also through Interface Builder) the IBOutlet reference to the custom UIStackView instance:

@IBOutlet weak var stackView: MyStackView!

Take the idea and adapt it to your needs. Hope this can help you!

You can use sklearn.preprocessing.LabelBinarizer:

Example:

import sklearn.preprocessing
a = [1,0,3]
label_binarizer = sklearn.preprocessing.LabelBinarizer()
label_binarizer.fit(range(max(a)+1))
b = label_binarizer.transform(a)
print('{0}'.format(b))

output:

[[0 1 0 0]
 [1 0 0 0]
 [0 0 0 1]]

Amongst other things, you may initialize sklearn.preprocessing.LabelBinarizer() so that the output of transform is sparse.

You can use this if you have a list:

Address address = list.get(0);
String cityname = address.getLocality();

A VirtualHost would also work for this and may work better for you as you can host several projects without the need for subdirectories. Here's how you do it:

httpd.conf (or extra\httpd-vhosts.conf relative to httpd.conf. Trailing slashes "\" might cause it not to work):

NameVirtualHost *:80
# ...
<VirtualHost *:80>  
    DocumentRoot C:\projects\transitCalculator\trunk\
    ServerName transitcalculator.localhost
    <Directory C:\projects\transitCalculator\trunk\>  
        Order allow,deny  
        Allow from all  
    </Directory>
</VirtualHost> 

HOSTS file (c:\windows\system32\drivers\etc\hosts usually):

# localhost entries
127.0.0.1 localhost transitcalculator.localhost

Now restart XAMPP and you should be able to access http://transitcalculator.localhost/ and it will map straight to that directory.

This can be helpful if you're trying to replicate a production environment where you're developing a site that will sit on the root of a domain name. You can, for example, point to files with absolute paths that will carry over to the server:

<img src="/images/logo.png" alt="My Logo" />

whereas in an environment using aliases or subdirectories, you'd need keep track of exactly where the "images" directory was relative to the current file.

To write a newline use \n not /n the latter is just a slash and a n

On python command line, first import that module for which you need location.

import module_name

Then type:

print(module_name.__file__)

For example to find out "pygal" location:

import pygal
print(pygal.__file__)

Output:

/anaconda3/lib/python3.7/site-packages/pygal/__init__.py

MacOS High Sierra is very crazy to update openssl command suddenly.

C99 has a bool type. To use it,

#include <stdbool.h>

Ok, solved it myself;

def sout = new StringBuilder(), serr = new StringBuilder()
def proc = 'ls /badDir'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println "out> $sout\nerr> $serr"

displays:

out> err> ls: cannot access /badDir: No such file or directory

I found a problem with Tobias Cohen's code (I don't have enough points to comment on it directly), which otherwise works for me. If you have two select options with the same name, both with value="", the original code will produce "name":"" instead of "name":["",""]

I think this can fixed by adding " || o[this.name] == ''" to the first if condition:

$.fn.serializeObject = function()
{
    var o = {};
    var a = this.serializeArray();
    $.each(a, function() {
        if (o[this.name] || o[this.name] == '') {
            if (!o[this.name].push) {
                o[this.name] = [o[this.name]];
            }
            o[this.name].push(this.value || '');
        } else {
            o[this.name] = this.value || '';
        }
    });
    return o;

In PS 7, you can use ConvertFrom-SecureString and -AsPlainText:

 $UnsecurePassword = ConvertFrom-SecureString -SecureString $SecurePassword -AsPlainText

Simple workaround to this problem to compare date part only

var _My_ResetSet_Array = _DB
                    .tbl_MyTable
                    .Where(x => x.Active == true && 
                               x.DateTimeValueColumn.Year == DateTime.Now.Year
                            && x.DateTimeValueColumn.Month == DateTime.Now.Month
                            && x.DateTimeValueColumn.Day == DateTime.Now.Day);

Because 'Date' datatype is not supported by linq to entity , where as Year, Month and Day are 'int' datatypes and are supported.

Note:

This answer just covers the timing differences between await in series and Promise.all. Be sure to read @mikep's comprehensive answer that also covers the more important differences in error handling.

For the purposes of this answer I will be using some example methods:

• res(ms) is a function that takes an integer of milliseconds and returns a promise that resolves after that many milliseconds.
• rej(ms) is a function that takes an integer of milliseconds and returns a promise that rejects after that many milliseconds.

Calling res starts the timer. Using Promise.all to wait for a handful of delays will resolve after all the delays have finished, but remember they execute at the same time:

const data = await Promise.all([res(3000), res(2000), res(1000)])
//                              ^^^^^^^^^  ^^^^^^^^^  ^^^^^^^^^
//                               delay 1    delay 2    delay 3
//
// ms ------1---------2---------3
// =============================O delay 1
// ===================O           delay 2
// =========O                     delay 3
//
// =============================O Promise.all

async function example() {
  const start = Date.now()
  let i = 0
  function res(n) {
    const id = ++i
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        resolve()
        console.log(`res #${id} called after ${n} milliseconds`, Date.now() - start)
      }, n)
    })
  }

  const data = await Promise.all([res(3000), res(2000), res(1000)])
  console.log(`Promise.all finished`, Date.now() - start)
}

example()

This means that Promise.all will resolve with the data from the inner promises after 3 seconds.

But, Promise.all has a "fail fast" behavior:

const data = await Promise.all([res(3000), res(2000), rej(1000)])
//                              ^^^^^^^^^  ^^^^^^^^^  ^^^^^^^^^
//                               delay 1    delay 2    delay 3
//
// ms ------1---------2---------3
// =============================O delay 1
// ===================O           delay 2
// =========X                     delay 3
//
// =========X                     Promise.all

async function example() {
  const start = Date.now()
  let i = 0
  function res(n) {
    const id = ++i
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        resolve()
        console.log(`res #${id} called after ${n} milliseconds`, Date.now() - start)
      }, n)
    })
  }
  
  function rej(n) {
    const id = ++i
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        reject()
        console.log(`rej #${id} called after ${n} milliseconds`, Date.now() - start)
      }, n)
    })
  }
  
  try {
    const data = await Promise.all([res(3000), res(2000), rej(1000)])
  } catch (error) {
    console.log(`Promise.all finished`, Date.now() - start)
  }
}

example()

If you use async-await instead, you will have to wait for each promise to resolve sequentially, which may not be as efficient:

const delay1 = res(3000)
const delay2 = res(2000)
const delay3 = rej(1000)

const data1 = await delay1
const data2 = await delay2
const data3 = await delay3

// ms ------1---------2---------3
// =============================O delay 1
// ===================O           delay 2
// =========X                     delay 3
//
// =============================X await

async function example() {
  const start = Date.now()
  let i = 0
  function res(n) {
    const id = ++i
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        resolve()
        console.log(`res #${id} called after ${n} milliseconds`, Date.now() - start)
      }, n)
    })
  }
  
  function rej(n) {
    const id = ++i
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        reject()
        console.log(`rej #${id} called after ${n} milliseconds`, Date.now() - start)
      }, n)
    })
  }
  
  try {
    const delay1 = res(3000)
    const delay2 = res(2000)
    const delay3 = rej(1000)

    const data1 = await delay1
    const data2 = await delay2
    const data3 = await delay3
  } catch (error) {
    console.log(`await finished`, Date.now() - start)
  }
}

You can also use a callable in the default field, such as:

b = models.CharField(max_length=7, default=foo)

And then define the callable:

def foo():
    return 'bar'

This was not mentioned here with offsetting.

You can use absolute to position for the left sidebar.

CSS

.sidebar-fixed{
  width: 16.66666667%;
  height: 100%;
}

HTML

<div class="row">
  <div class="sidebar-fixed">
    Side Bar
  </div>
  <div class="col-md-10 col-md-offset-2">
    CONTENT
  </div>
</div>

The Easiest way to change the action bar name is to go to the AndroidManifest.xml and type this code.

<activity android:name=".MainActivity"
    android:label="Your Label> </activity>

CER is an X.509 certificate in binary form, DER encoded.
CRT is a binary X.509 certificate, encapsulated in text (base-64) encoding.

It is not the same encoding.

Not a simple way, no.

Let's say that by "active" you mean "hasn't passed the maximum lifetime" and hasn't been explicitly destroyed and that you're using the default session handler.

• First, the maximum lifetime is defined as a php.ini config and is defined in terms of the last activity on the session. So the "expiry" mechanism would have to read the content of the sessions to determine the application-defined expiry.
• Second, you'd have to manually read the sessions directory and read the files, whose format I don't even know they're in.

If you really need this, you must implement some sort of custom session handler. See session_set_save_handler.

Take also in consideration that you'll have no feedback if the user just closes the browser or moves away from your site without explciitly logging out. Depending on much inactivity you consider the threshold to deem a session "inactive", the number of false positives you'll get may be very high.

There is a better answer to this problem, though I could just break this down step-by-step.

You will need to fetch and checkout the latest upstream changes like so, e.g.:

git fetch upstream
git checkout upstream/master -b revert/john/foo_and_bar

Taking a look at the commit log, you should find something similar to this:

commit b76a5f1f5d3b323679e466a1a1d5f93c8828b269
Merge: 9271e6e a507888
Author: Tim Tom <[email protected]>
Date:   Mon Apr 29 06:12:38 2013 -0700

    Merge pull request #123 from john/foo_and_bar

    Add foo and bar

commit a507888e9fcc9e08b658c0b25414d1aeb1eef45e
Author: John Doe <[email protected]>
Date:   Mon Apr 29 12:13:29 2013 +0000

    Add bar

commit 470ee0f407198057d5cb1d6427bb8371eab6157e
Author: John Doe <[email protected]>
Date:   Mon Apr 29 10:29:10 2013 +0000

    Add foo

Now you want to revert the entire pull request with the ability to unrevert later. To do so, you will need to take the ID of the merge commit.

In the above example the merge commit is the top one where it says "Merged pull request #123...".

Do this to revert the both changes ("Add bar" and "Add foo") and you will end up with in one commit reverting the entire pull request which you can unrevert later on and keep the history of changes clean:

git revert -m 1 b76a5f1f5d3b323679e466a1a1d5f93c8828b269

Simply you can write the following code snippet to convert an OpenCV image into a grey scale image

import cv2
image = cv2.imread('image.jpg',0)
cv2.imshow('grey scale image',image)

Observe that the image.jpg and the code must be saved in same folder.

Note that:

• ('image.jpg') gives a RGB image
• ('image.jpg',0) gives Grey Scale Image.

yum -y remove php* to remove all php packages then you can install the 5.6 ones.

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray(); 
encImage = Base64.encodeToString(b, Base64.DEFAULT);

Try this:

var src = DateTime.Now;
var hm = new DateTime(src.Year, src.Month, src.Day, src.Hour, src.Minute, 0);

Try this code:

final File f = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());

replace 'MyClass' with your class containing the main method.

Alternatively you can also use

System.getProperty("java.class.path")

Above mentioned System property provides

Path used to find directories and JAR archives containing class files. Elements of the class path are separated by a platform-specific character specified in the path.separator property.

This worked for me:

location / {
    try_files $uri $uri/ /base.html;
}

I've just started using OSX. Free editors of note that I've discovered:

• Komodo by ActiveState. No debugger or regex editor (although one comes with Python, i.e. redemo.py) in free version but perfectly usable.
• ERIC, written in PyQT.
• Eclipse with PyDev is my preferred option for editing Python on all platforms. Nice clean GUI, decent debugger. Good syntax parsing etc.

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

I would go with a simple regex which will check that days doesn't have more than 31 days and months no more than 12. Something like:

(0?[1-9]|[12][0-9]|3[01])-(0?[1-9]|1[012])-((18|19|20|21)\\d\\d)

This is the format "dd-MM-yyyy". You can tweak it to your needs (for example take off the ? to make the leading 0 required - now its optional), and then use a custom logic to cut down to the specific rules like leap years February number of days case, and other months number of days cases. See the DateChecker code below.

I am choosing this approach since I tested that this is the best one when performance is taken into account. I checked this (1st) approach versus 2nd approach of validating a date against a regex that takes care of the other use cases, and 3rd approach of using the same simple regex above in combination with SimpleDateFormat.parse(date).
The 1st approach was 4 times faster than the 2nd approach, and 8 times faster than the 3rd approach. See the self contained date checker and performance tester main class at the bottom. One thing that I left unchecked is the joda time approach(s). (The more efficient date/time library).

Date checker code:

class DateChecker {

    private Matcher matcher;
    private Pattern pattern;

    public DateChecker(String regex) {
        pattern = Pattern.compile(regex);
    }

    /**
     * Checks if the date format is a valid.
     * Uses the regex pattern to match the date first. 
     * Than additionally checks are performed on the boundaries of the days taken the month into account (leap years are covered).
     * 
     * @param date the date that needs to be checked.
     * @return if the date is of an valid format or not.
     */
    public boolean check(final String date) {
        matcher = pattern.matcher(date);
        if (matcher.matches()) {
            matcher.reset();
            if (matcher.find()) {
                int day = Integer.parseInt(matcher.group(1));
                int month = Integer.parseInt(matcher.group(2));
                int year = Integer.parseInt(matcher.group(3));

                switch (month) {
                case 1:
                case 3:
                case 5:
                case 7:
                case 8:
                case 10:
                case 12: return day < 32;
                case 4:
                case 6:
                case 9:
                case 11: return day < 31;
                case 2: 
                    int modulo100 = year % 100;
                    //http://science.howstuffworks.com/science-vs-myth/everyday-myths/question50.htm
                    if ((modulo100 == 0 && year % 400 == 0) || (modulo100 != 0 && year % LEAP_STEP == 0)) {
                        //its a leap year
                        return day < 30;
                    } else {
                        return day < 29;
                    }
                default:
                    break;
                }
            }
        }
        return false;
    }

    public String getRegex() {
        return pattern.pattern();

Some useful notes:
- to enable the assertions (assert checks) you need to use -ea argument when running the tester. (In eclipse this is done by editing the Run/Debug configuration -> Arguments tab -> VM Arguments -> insert "-ea"
- the regex above is bounded to years 1800 to 2199
- you don't need to use ^ at the beginning and $ at the end to match only the whole date string. The String.matches takes care of that.
- make sure u check the valid and invalid cases and change them according the rules that you have.
- the "only whole string" version of each regex gives the same speed as the "normal" version (the one without ^ and $). If you see performance differences this is because java "gets used" to processing the same instructions so the time lowers. If you switch the lines where the "normal" and the "only whole string" version execute, you will see this proven.

Hope this helps someone!

Use chardet https://github.com/chardet/chardet (documentation is short and easy to read).

Install python, then pip install chardet, at last use the command line command.

I tested under GB2312 and it's pretty accurate. (Make sure you have at least a few characters, sample with only 1 character may fail easily).

file is not reliable as you can see.

Using apache commons..

//For midnight today 
Date today = new Date(); 
DateUtils.truncate(today, Calendar.DATE);

//For midnight tomorrow   
Date tomorrow = DateUtils.addDays(today, 1); 
DateUtils.truncate(tomorrow, Calendar.DATE);

I am using the Sublime Text keymap and the keybinding provided by the top answer did not seem to work :( Could be some conflicts between Visual Studio Code and sublime keymaps.

The keybinding recommended by @Han works for me (much appreciated!):

• Enter multiline cursor mode with Ctrl + Shift + Up/Down
• Exit with Esc

(Sidenote) Below is a small example of using Emmet together with the multiline cursor (enabled and disabled with these key bindings listed above):

You can do something like this.

$a = start-process -NoNewWindow powershell {timeout 10; 'done'} -PassThru

And if you want to wait for it:

$a | wait-process

Bonus osx or linux version:

$a = start-process pwsh '-c',{start-sleep 5; 'done'} -PassThru 

Example pinger script I have. The args are passed as an array:

$1 = start -n powershell pinger,comp001 -pa

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

also works. First create a JFrame called frame, then add this code underneath.

Here are the two functions I use. They are based on matrix rotations. and can rotate around arbitrary axes. To rotate using the world's axes you would want to use the second function rotateAroundWorldAxis().

// Rotate an object around an arbitrary axis in object space
var rotObjectMatrix;
function rotateAroundObjectAxis(object, axis, radians) {
    rotObjectMatrix = new THREE.Matrix4();
    rotObjectMatrix.makeRotationAxis(axis.normalize(), radians);

    // old code for Three.JS pre r54:
    // object.matrix.multiplySelf(rotObjectMatrix);      // post-multiply
    // new code for Three.JS r55+:
    object.matrix.multiply(rotObjectMatrix);

    // old code for Three.js pre r49:
    // object.rotation.getRotationFromMatrix(object.matrix, object.scale);
    // old code for Three.js r50-r58:
    // object.rotation.setEulerFromRotationMatrix(object.matrix);
    // new code for Three.js r59+:
    object.rotation.setFromRotationMatrix(object.matrix);
}

var rotWorldMatrix;
// Rotate an object around an arbitrary axis in world space       
function rotateAroundWorldAxis(object, axis, radians) {
    rotWorldMatrix = new THREE.Matrix4();
    rotWorldMatrix.makeRotationAxis(axis.normalize(), radians);

    // old code for Three.JS pre r54:
    //  rotWorldMatrix.multiply(object.matrix);
    // new code for Three.JS r55+:
    rotWorldMatrix.multiply(object.matrix);                // pre-multiply

    object.matrix = rotWorldMatrix;

    // old code for Three.js pre r49:
    // object.rotation.getRotationFromMatrix(object.matrix, object.scale);
    // old code for Three.js pre r59:
    // object.rotation.setEulerFromRotationMatrix(object.matrix);
    // code for r59+:
    object.rotation.setFromRotationMatrix(object.matrix);
}

So you should call these functions within your anim function (requestAnimFrame callback), resulting in a rotation of 90 degrees on the x-axis:

var xAxis = new THREE.Vector3(1,0,0);
rotateAroundWorldAxis(mesh, xAxis, Math.PI / 180);

I use eventbug plugin to firebug for this purpose.

I was having the same sort of problem. Apparently it's simply because PHP doesn't recognise utf-8.

I was tearing my hair out at first when a '£' sign kept showing up as '£', despite it appearing ok in DreamWeaver. Eventually I remembered I had been having problems with links relative to the index file, when the pages, if viewed directly would work with slideshows, but not when used with an include (but that's beside the point. Anyway I wondered if this might be a similar problem, so instead of putting into the page that I was having problems with, I simply put it into the index.php file - problem fixed throughout.

Use substring method like this::

str.substring(str.length()-2);

Needed background on concurrency approaches:

Different web servers implement different techniques for handling incoming HTTP requests in parallel. A pretty popular technique is using threads -- that is, the web server will create/dedicate a single thread for each incoming request. The Apache HTTP web server supports multiple models for handling requests, one of which (called the worker MPM) uses threads. But it supports another concurrency model called the prefork MPM which uses processes -- that is, the web server will create/dedicate a single process for each request.

There are also other completely different concurrency models (using Asynchronous sockets and I/O), as well as ones that mix two or even three models together. For the purpose of answering this question, we are only concerned with the two models above, and taking Apache HTTP server as an example.

Needed background on how PHP "integrates" with web servers:

PHP itself does not respond to the actual HTTP requests -- this is the job of the web server. So we configure the web server to forward requests to PHP for processing, then receive the result and send it back to the user. There are multiple ways to chain the web server with PHP. For Apache HTTP Server, the most popular is "mod_php". This module is actually PHP itself, but compiled as a module for the web server, and so it gets loaded right inside it.

There are other methods for chaining PHP with Apache and other web servers, but mod_php is the most popular one and will also serve for answering your question.

You may not have needed to understand these details before, because hosting companies and GNU/Linux distros come with everything prepared for us.

Now, onto your question!

Since with mod_php, PHP gets loaded right into Apache, if Apache is going to handle concurrency using its Worker MPM (that is, using Threads) then PHP must be able to operate within this same multi-threaded environment -- meaning, PHP has to be thread-safe to be able to play ball correctly with Apache!

At this point, you should be thinking "OK, so if I'm using a multi-threaded web server and I'm going to embed PHP right into it, then I must use the thread-safe version of PHP". And this would be correct thinking. However, as it happens, PHP's thread-safety is highly disputed. It's a use-if-you-really-really-know-what-you-are-doing ground.

Final notes

In case you are wondering, my personal advice would be to not use PHP in a multi-threaded environment if you have the choice!

Speaking only of Unix-based environments, I'd say that fortunately, you only have to think of this if you are going to use PHP with Apache web server, in which case you are advised to go with the prefork MPM of Apache (which doesn't use threads, and therefore, PHP thread-safety doesn't matter) and all GNU/Linux distributions that I know of will take that decision for you when you are installing Apache + PHP through their package system, without even prompting you for a choice. If you are going to use other webservers such as nginx or lighttpd, you won't have the option to embed PHP into them anyway. You will be looking at using FastCGI or something equal which works in a different model where PHP is totally outside of the web server with multiple PHP processes used for answering requests through e.g. FastCGI. For such cases, thread-safety also doesn't matter. To see which version your website is using put a file containing <?php phpinfo(); ?> on your site and look for the Server API entry. This could say something like CGI/FastCGI or Apache 2.0 Handler.

If you also look at the command-line version of PHP -- thread safety does not matter.

Finally, if thread-safety doesn't matter so which version should you use -- the thread-safe or the non-thread-safe? Frankly, I don't have a scientific answer! But I'd guess that the non-thread-safe version is faster and/or less buggy, or otherwise they would have just offered the thread-safe version and not bothered to give us the choice!

Use replace method of string like the following way:

String x="\"abcd";
String z=x.replace("\"", "");
System.out.println(z);

Output:

abcd

For *nix OSes, run wireshark with sudo privileges. You need to be superuser in order to be able to view interfaces. Just like running tcpdump -D vs sudo tcpdump -D, the first one won't show any of the interfaces, won't compalain/prompt for sudo privileges either.

So, from terminal, run:

$ sudo wireshark

I am now using Google Apps (for Email) and Heroku as web server. I am using Google Apps 301 Permanent Redirect feature to redirect the naked domain to WWW.your_domain.com

It's shorthand for tags.map { |tag| tag.name }.join(' ')

A keystore needs a keystore file. The KeyStore class needs a FileInputStream. But if you supply null (instead of FileInputStream instance) an empty keystore will be loaded. Once you create a keystore, you can verify its integrity using keytool.

Following code creates an empty keystore with empty password

  KeyStore ks2 = KeyStore.getInstance("jks");
  ks2.load(null,"".toCharArray());
  FileOutputStream out = new FileOutputStream("C:\\mykeytore.keystore");
  ks2.store(out, "".toCharArray());

Once you have the keystore, importing certificate is very easy. Checkout this link for the sample code.

You also can try out this

   final WebView webView = new WebView(this);
            webView.loadDataWithBaseURL(null, content, "text/html", "UTF-8", null);

driver = webdriver.Firefox(...)  # Or Chrome(), or Ie(), or Opera()

username = driver.find_element_by_id("username")
password = driver.find_element_by_id("password")

username.send_keys("YourUsername")
password.send_keys("Pa55worD")

driver.find_element_by_name("submit").click()

Notes to your code:

• find_element_by_name('Username'): Username capitalized doesn't match anything.
• Select() is used to act on a Select Element (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select)

If you what to add bootstrap attributes in anchor tag dynamically than this will helps you lot

 $(".dropdown a").attr({
      class: "dropdown-toggle",
     'data-toggle': "dropdown",
      role: "button",
     'aria-haspopup': "true",
     'aria-expanded': "true"
});

All major browsers now include native JSON encoding/decoding.

// To encode an object (This produces a string)
var json_str = JSON.stringify(myobject); 

// To decode (This produces an object)
var obj = JSON.parse(json_str);

Note that only valid JSON data will be encoded. For example:

var obj = {'foo': 1, 'bar': (function (x) { return x; })}
JSON.stringify(obj) // --> "{\"foo\":1}"

Valid JSON types are: objects, strings, numbers, arrays, true, false, and null.

Some JSON resources:

• JSON on Mozilla Developer Network
• JSON on Wikipedia

Go to The Gradle Console in bottom right and open it.Here you will be seeing some https/https calls click on the links and open them in web browser then try clean build it worked for me.

I think It is happening because studio is not able to get the response from the hit.

You can't update two tables at once, but you can link an update into an insert using OUTPUT INTO, and you can use this output as a join for the second update:

DECLARE @ids TABLE (id int);
BEGIN TRANSACTION

UPDATE Table1 
SET Table1.LastName = 'DR. XXXXXX'  
OUTPUT INSERTED.id INTO @ids
WHERE Table1.field = '010008';

UPDATE Table2 
SET Table2.WAprrs = 'start,stop' 
FROM Table2 
JOIN @ids i on i.id = Table2.id;

COMMIT;

I changed your example WHERE condition to be some other field than id. If it's id the you don't need this fancy OUTPUT, you can just UPDATE the second table for the same id='010008'.

A very short way to do it is just right click on the activity_main.xml design background and select convert view then select Relativealayout. Your code in Xml Text will auto. Change. Goodluck

As Html.fromHtml deprecated I simply I used this code to get String2 in next line.

textView.setText(fromHtml("String1 <br/> String2"));

.

@SuppressWarnings("deprecation")
    public static Spanned fromHtml(String html){
        Spanned result;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
            result = Html.fromHtml(html,Html.FROM_HTML_MODE_LEGACY);
        } else {
            result = Html.fromHtml(html);

        return result;

Alright, I had the same problem, and none of these answers worked for me (I'm running Windows 8). I tried running tools/android.bat and noticed I got some errors there. I investigated further and it seems there is something wrong in the code that finds your Java path.

This is how you fix it:

1. Open up tools/android.bat in your favorite text editor

2. Search for this piece of code:

   set java_exe=
   call lib\find_java.bat
   if not defined java_exe goto :EOF
   

3. Replace it with this:

   set java_exe=D:\Program Files\Java\jdk1.7.0_07\bin\java.exe 
   

   where the path is the path to your Java exe.

4. Run android.bat

(in my case I had to specify the path to java_exe in step 3 with no quotes to make it work.)

If you are doing these same assignments a lot in your program and want a shortcut, the most straightforward solution might be to just add a function

static inline void set_coordinates(
        GLfloat coordinates[static 8],
        GLfloat c0, GLfloat c1, GLfloat c2, GLfloat c3,
        GLfloat c4, GLfloat c5, GLfloat c6, GLfloat c7)
{
    coordinates[0] = c0;
    coordinates[1] = c1;
    coordinates[2] = c2;
    coordinates[3] = c3;
    coordinates[4] = c4;
    coordinates[5] = c5;
    coordinates[6] = c6;
    coordinates[7] = c7;
}

and then simply call

GLfloat coordinates[8];
// ...
set_coordinates(coordinates, 1.0f, 0.0f, 1.0f, 1.0f, 0.0f, 1.0f, 0.0f, 0.0f);

not really sure what you're doing exactly via the context of your code but...

why make the listOfTopicAuthors variable at all?

List<String> list = Arrays.asList((....).toArray( new String[0] ) );

the "...." represents however your set came into play, whether it's new or came from another location.

To find the specific error run this:

SHOW ENGINE INNODB STATUS;

And look in the LATEST FOREIGN KEY ERROR section.

The data type for the child column must match the parent column exactly. For example, since medicalhistory.MedicalHistoryID is an INT, Patient.MedicalHistory also needs to be an INT, not a SMALLINT.

Also, you should run the query set foreign_key_checks=0 before running the DDL so you can create the tables in an arbitrary order rather than needing to create all parent tables before the relevant child tables.

Open a new worksheet on the related instance (Alt-F10) and run the following query

SELECT view_name, owner
FROM sys.all_views 
ORDER BY owner, view_name

This looks like a problem with line endings in your code. If you're going to be using all these other scientific packages, you may as well use Pandas for the CSV reading part, which is both more robust and more useful than just the csv module:

import pandas
colnames = ['year', 'name', 'city', 'latitude', 'longitude']
data = pandas.read_csv('test.csv', names=colnames)

If you want your lists as in the question, you can now do:

names = data.name.tolist()
latitude = data.latitude.tolist()
longitude = data.longitude.tolist()

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:

A data frame of four rows:

df = pd.DataFrame({'A': [1,2,3,4]})

Now trying to assign a list/array of two elements to it:

df['B'] = [3,4]   # or df['B'] = np.array([3,4])

Both errors out:

ValueError: Length of values does not match length of index

Because the data frame has four rows but the list and array has only two elements.

Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:

df['B'] = pd.Series([3,4])

df
#   A     B
#0  1   3.0
#1  2   4.0
#2  3   NaN          # NaN because the value at index 2 and 3 doesn't exist in the Series
#3  4   NaN

For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:

df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))

#   A     B
#0  1   1.0
#1  2   5.0
#2  7   9.0
#3  8   NaN

Although rather late, but you can manually download the required DLLs from nuget at the following link: https://www.nuget.org/packages/Microsoft.ReportViewer.Runtime.Common/12.0.2402.15

Open the file .Rar Archive, extract the dlls and copy them manually to the bin folder of your publish.

This solution worked for me. Hope that helps !!

Do not use urlArgs for this!

Require script loads respect http caching headers. (Scripts are loaded with a dynamically inserted <script>, which means the request looks just like any old asset getting loaded.)

Serve your javascript assets with the proper HTTP headers to disable caching during development.

Using require's urlArgs means any breakpoints you set will not be preserved across refreshes; you end up needing to put debugger statements everywhere in your code. Bad. I use urlArgs for cache-busting assets during production upgrades with the git sha; then I can set my assets to be cached forever and be guaranteed to never have stale assets.

In development, I mock all ajax requests with a complex mockjax configuration, then I can serve my app in javascript-only mode with a 10 line python http server with all caching turned off. This has scaled up for me to a quite large "enterprisey" application with hundreds of restful webservice endpoints. We even have a contracted designer who can work with our real production codebase without giving him access to our backend code.

You would probably use your example like this

var newText = "<span>" + $("p").text().split(" ").join("</span> <span>") + "</span>";

This will put span tags around all the words in you paragraphs, turning

<p>Test is a demo.</p>

into

<p><span>Test</span> <span>is</span> <span>a</span> <span>demo.</span></p>

I do not know what the practical use of this could be.

You can use a single group for seconds/minutes. The following expression may suit your needs:

([0-9]+)\s*(seconds|minutes)

• 401 (Unauthorized) response header -> Request authentication header

• Here are several WWW-Authenticate response headers. (The full list is at IANA: HTTP Authentication Schemes.)

  • WWW-Authenticate: Basic-> Authorization: Basic + token - Use for basic authentication
  • WWW-Authenticate: NTLM-> Authorization: NTLM + token (2 challenges)
  • WWW-Authenticate: Negotiate -> Authorization: Negotiate + token - used for Kerberos authentication
    • By the way: IANA has this angry remark about Negotiate: This authentication scheme violates both HTTP semantics (being connection-oriented) and syntax (use of syntax incompatible with the WWW-Authenticate and Authorization header field syntax).

You can set the Authorization: Basic header only when you also have the WWW-Authenticate: Basic header on your 401 challenge.

But since you have WWW-Authenticate: Negotiate this should be the case for Kerberos based authentication.

url_for in Flask is used for creating a URL to prevent the overhead of having to change URLs throughout an application (including in templates). Without url_for, if there is a change in the root URL of your app then you have to change it in every page where the link is present.

Syntax: url_for('name of the function of the route','parameters (if required)')

It can be used as:

@app.route('/index')
@app.route('/')
def index():
    return 'you are in the index page'

Now if you have a link the index page:you can use this:

<a href={{ url_for('index') }}>Index</a>

You can do a lot o stuff with it, for example:

@app.route('/questions/<int:question_id>'):    #int has been used as a filter that only integer will be passed in the url otherwise it will give a 404 error
def find_question(question_id):  
    return ('you asked for question{0}'.format(question_id))

For the above we can use:

<a href = {{ url_for('find_question' ,question_id=1) }}>Question 1</a>

Like this you can simply pass the parameters!

Yes, Java (similar to other mainstream languages) uses lazy evaluation short-circuiting which means it evaluates as little as possible.

This means that the following code is completely safe:

if(p != null && p.getAge() > 10)

Also, a || b never evaluates b if a evaluates to true.

In Laravel:

Add set_time_limit(0) line on top of query.

set_time_limit(0);

$users = App\User::all();

It helps you in different large queries but you should need to improve query optimise.

HTML does not support a dropdown list with checkboxes. You can have a dropdown list, or a checkbox list. You could possibly fake a dropdowncheckbox list using javascript and hiding divs, but that would be less reliable than just a standard checkbox list.

There are of course 3rd party controls that look like a dropdown checkboxlist, but they are using the div tricks.

you could also use a double listbox, which handles multi select by moving items back and forth between two lists. This has the added benefit of being easily to see all the selected items at once, even though the list of total items is long

(Imagine a list of every city in the world, with only the first and last selected)

For me (also XAMPP on Windows 7), this is what worked:

<Directory "C:\projects\myfolder\htdocs">`
   AllowOverride All
   Require all granted
   Options Indexes FollowSymLinks
</Directory>` 

It is this line that would cause the 403:

Order allow,deny

I was recently reading more on difference between :joins and :includes in rails. Here is an explaination of what I understood (with examples :))

Consider this scenario:

• A User has_many comments and a comment belongs_to a User.

• The User model has the following attributes: Name(string), Age(integer). The Comment model has the following attributes:Content, user_id. For a comment a user_id can be null.

Joins:

:joins performs a inner join between two tables. Thus

Comment.joins(:user)

#=> <ActiveRecord::Relation [#<Comment id: 1, content: "Hi I am Aaditi.This is my first   comment!", user_id: 1, created_at: "2014-11-12 18:29:24", updated_at: "2014-11-12 18:29:24">, 
     #<Comment id: 2, content: "Hi I am Ankita.This is my first comment!", user_id: 2, created_at: "2014-11-12 18:29:29", updated_at: "2014-11-12 18:29:29">,    
     #<Comment id: 3, content: "Hi I am John.This is my first comment!", user_id: 3, created_at: "2014-11-12 18:30:25", updated_at: "2014-11-12 18:30:25">]>

will fetch all records where user_id (of comments table) is equal to user.id (users table). Thus if you do

Comment.joins(:user).where("comments.user_id is null")

#=> <ActiveRecord::Relation []>

You will get a empty array as shown.

Moreover joins does not load the joined table in memory. Thus if you do

comment_1 = Comment.joins(:user).first

comment_1.user.age
#=>?[1m?[36mUser Load (0.0ms)?[0m  ?[1mSELECT "users".* FROM "users" WHERE "users"."id" = ? ORDER BY "users"."id" ASC LIMIT 1?[0m  [["id", 1]]
#=> 24

As you see, comment_1.user.age will fire a database query again in the background to get the results

Includes:

:includes performs a left outer join between the two tables. Thus

Comment.includes(:user)

#=><ActiveRecord::Relation [#<Comment id: 1, content: "Hi I am Aaditi.This is my first comment!", user_id: 1, created_at: "2014-11-12 18:29:24", updated_at: "2014-11-12 18:29:24">,
   #<Comment id: 2, content: "Hi I am Ankita.This is my first comment!", user_id: 2, created_at: "2014-11-12 18:29:29", updated_at: "2014-11-12 18:29:29">,
   #<Comment id: 3, content: "Hi I am John.This is my first comment!", user_id: 3, created_at: "2014-11-12 18:30:25", updated_at: "2014-11-12 18:30:25">,    
   #<Comment id: 4, content: "Hi This is an anonymous comment!", user_id: nil, created_at: "2014-11-12 18:31:02", updated_at: "2014-11-12 18:31:02">]>

will result in a joined table with all the records from comments table. Thus if you do

Comment.includes(:user).where("comment.user_id is null")
#=> #<ActiveRecord::Relation [#<Comment id: 4, content: "Hi This is an anonymous comment!", user_id: nil, created_at: "2014-11-12 18:31:02", updated_at: "2014-11-12 18:31:02">]>

it will fetch records where comments.user_id is nil as shown.

Moreover includes loads both the tables in the memory. Thus if you do

comment_1 = Comment.includes(:user).first

comment_1.user.age
#=> 24

As you can notice comment_1.user.age simply loads the result from memory without firing a database query in the background.

Use either this:

:active {
    outline:none;
}

or this if that doesn't work:

:active {
   outline:none !important;
}

This works for me (FF and Chrome, at least). Instead of targeting the :focus state, just target the :active state and that will remove the aesthetically obtrusive highlighting in your browser when a user clicks a link. But it will still retain the focus states when a user with disabilities tabs or shift-tabs through a page. Both parties are happy. :)

This is a method for converting a svg picture to a gif using standard php GD tools

1) You put the image into a canvas element in the browser:

<canvas id=myCanvas></canvas>

<script>
var Key='picturename'
var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
base_image = new Image();
base_image.src = myimage.svg;
base_image.onload = function(){

    //get the image info as base64 text string

    var dataURL = canvas.toDataURL();
    //Post the image (dataURL) to the server using jQuery post method
    $.post('ProcessPicture.php',{'TheKey':Key,'image': dataURL ,'h': canvas.height,'w':canvas.width,"stemme":stemme } ,function(data,status){ alert(data+' '+status) });
}
</script>    

And then convert it at the server (ProcessPicture.php) from (default) png to gif and save it. (you could have saved as png too then use imagepng instead of image gif):

//receive the posted data in php
$pic=$_POST['image'];
$Key=$_POST['TheKey'];
$height=$_POST['h'];
$width=$_POST['w'];
$dir='../gif/'
$gifName=$dir.$Key.'.gif';
 $pngName=$dir.$Key.'.png';

//split the generated base64 string before the comma. to remove the 'data:image/png;base64, header  created by and get the image data
$data = explode(',', $pic);
$base64img = base64_decode($data[1]);
$dimg=imagecreatefromstring($base64img); 

//in order to avoid copying a black figure into a (default) black background you must create a white background

$im_out = ImageCreateTrueColor($width,$height);
$bgfill = imagecolorallocate( $im_out, 255, 255, 255 );
imagefill( $im_out, 0,0, $bgfill );

//Copy the uploaded picture in on the white background
ImageCopyResampled($im_out, $dimg ,0, 0, 0, 0, $width, $height,$width, $height);

//Make the gif and png file 
imagegif($im_out, $gifName);
imagepng($im_out, $pngName);

You should use UNION if you want to combine different resultsets. Try the following:

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id  
        WHERE products_id = 181) AS A)
UNION 

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id 
        WHERE products_id = 180) AS B
ON A.orders_id=B.orders_id)

{PowerManager mgr = (PowerManager)context.getSystemService(Context.POWER_SERVICE);
WakeLock wakeLock = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"MyWakeLock"); 
wakeLock.acquire();}

The Clone() method returns a new array (a shallow copy) object containing all the elements in the original array. The CopyTo() method copies the elements into another existing array. Both perform a shallow copy. A shallow copy means the contents (each array element) contains references to the same object as the elements in the original array. A deep copy (which neither of these methods performs) would create a new instance of each element's object, resulting in a different, yet identical object.

So the difference are :

1- CopyTo require to have a destination array when Clone return a new array.
2- CopyTo let you specify an index (if required) to the destination array.

Remove the wrong example.

add this to your form:

<form  id="regform" action="insert.php" method="post">

add this to your function:

<script>
    function myFunction() {
        var pass1 = document.getElementById("pass1").value;
        var pass2 = document.getElementById("pass2").value;
        if (pass1 != pass2) {
            //alert("Passwords Do not match");
            document.getElementById("pass1").style.borderColor = "#E34234";
            document.getElementById("pass2").style.borderColor = "#E34234";
        }
        else {
            alert("Passwords Match!!!");
            document.getElementById("regForm").submit();
        }
    }
</script>

I use JSONP.

Basically, you add

<script src="http://..../someData.js?callback=some_func"/>

on your page.

some_func() should get called so that you are notified that the data is in.

According to matplotlib documentation, The signature of the Axes class grid() method is as follows:

Axes.grid(b=None, which='major', axis='both', **kwargs)
Turn the axes grids on or off.

which can be ‘major’ (default), ‘minor’, or ‘both’ to control whether major tick grids, minor tick grids, or both are affected.

axis can be ‘both’ (default), ‘x’, or ‘y’ to control which set of gridlines are drawn.

So in order to show grid lines for both the x axis and y axis, we can use the the following code:

ax = plt.gca()
ax.grid(which='major', axis='both', linestyle='--')

This method gives us finer control over what to show for grid lines.

you can get filename by uri with simple way

Retrieving file information

fun get_filename_by_uri(uri : Uri) : String{
    contentResolver.query(uri, null, null, null, null).use { cursor ->
        cursor?.let {
            val nameIndex = it.getColumnIndex(OpenableColumns.DISPLAY_NAME)
            it.moveToFirst()
            return it.getString(nameIndex)
        }
    }
    return ""
}

and easy to read it by using

contentResolver.openInputStream(uri)

1. Create new project in Android studio;

2. Press Ctrl+Shift+Alt+S

3. Proceed to "Project" section

4. You can see actual gradle version and android pluging version. Copy that to your project.

git config --list

is one way to go. I usually just open up .gitconfig though.

You cannot specify that it's always a file. If you don't need xcopy's other features, why not just use regular copy?

Just to provide an another way, you can also simply use the following command

$ cat to_remove
/tmp/file1
/tmp/file2
/tmp/file3
$ rm $( cat to_remove )

There are several sources on the net suggesting a hack by reinstalling the package with the -m option and then just removing the .egg file in lib/ and the binaries in bin/. Also, discussion about this setuptools issue can be found on the python bug tracker as setuptools issue 21.

Edit: Added the link to the python bugtracker.

Try this. Edit your build.gradle file as followed.

ext { profile = project.hasProperty('profile') ? project['profile'] : 'local' }

When you do : f.readlines() you already read all the file so f.tell() will show you that you are in the end of the file, and doing f.next() will result in a StopIteration error.

Alternative of what you want to do is:

filne = "D:/testtube/testdkanimfilternode.txt"

with open(filne, 'r+') as f:
    for line in f:
        if line.startswith("anim "):
            print f.next() 
            # Or use next(f, '') to return <empty string> instead of raising a  
            # StopIteration if the last line is also a match.
            break

Although the question has been answered, let me mention some nuances.

Let's say you are interested in the first column of the array

arr = numpy.array([[1, 2],
                   [3, 4],
                   [5, 6]])

As you already know from other answers, to get it in the form of "row vector" (array of shape (3,)), you use slicing:

arr_col1_view = arr[:, 1]         # creates a view of the 1st column of the arr
arr_col1_copy = arr[:, 1].copy()  # creates a copy of the 1st column of the arr

To check if an array is a view or a copy of another array you can do the following:

arr_col1_view.base is arr  # True
arr_col1_copy.base is arr  # False

see ndarray.base.

Besides the obvious difference between the two (modifying arr_col1_view will affect the arr), the number of byte-steps for traversing each of them is different:

arr_col1_view.strides[0]  # 8 bytes
arr_col1_copy.strides[0]  # 4 bytes

see strides and this answer.

Why is this important? Imagine that you have a very big array A instead of the arr:

A = np.random.randint(2, size=(10000, 10000), dtype='int32')
A_col1_view = A[:, 1] 
A_col1_copy = A[:, 1].copy()

and you want to compute the sum of all the elements of the first column, i.e. A_col1_view.sum() or A_col1_copy.sum(). Using the copied version is much faster:

%timeit A_col1_view.sum()  # ~248 µs
%timeit A_col1_copy.sum()  # ~12.8 µs

This is due to the different number of strides mentioned before:

A_col1_view.strides[0]  # 40000 bytes
A_col1_copy.strides[0]  # 4 bytes

Although it might seem that using column copies is better, it is not always true for the reason that making a copy takes time too and uses more memory (in this case it took me approx. 200 µs to create the A_col1_copy). However if we needed the copy in the first place, or we need to do many different operations on a specific column of the array and we are ok with sacrificing memory for speed, then making a copy is the way to go.

In the case we are interested in working mostly with columns, it could be a good idea to create our array in column-major ('F') order instead of the row-major ('C') order (which is the default), and then do the slicing as before to get a column without copying it:

A = np.asfortranarray(A)   # or np.array(A, order='F')
A_col1_view = A[:, 1]
A_col1_view.strides[0]     # 4 bytes

%timeit A_col1_view.sum()  # ~12.6 µs vs ~248 µs

Now, performing the sum operation (or any other) on a column-view is as fast as performing it on a column copy.

Finally let me note that transposing an array and using row-slicing is the same as using the column-slicing on the original array, because transposing is done by just swapping the shape and the strides of the original array.

A[:, 1].strides[0]    # 40000 bytes
A.T[1, :].strides[0]  # 40000 bytes

Change this line

filename1 = datetime.now().strftime("%Y%m%d-%H%M%S")

To

filename1 = datetime.datetime.now().strftime("%Y%m%d-%H%M%S")

Note the extra datetime. Alternatively, change your import datetime to from datetime import datetime

Yeah it is possible with FileReader, I have already done an example of this, here's the code:

<!DOCTYPE html>
<html>
  <head>
    <title>Read File (via User Input selection)</title>
    <script type="text/javascript">
    var reader; //GLOBAL File Reader object for demo purpose only

    /**
     * Check for the various File API support.
     */
    function checkFileAPI() {
        if (window.File && window.FileReader && window.FileList && window.Blob) {
            reader = new FileReader();
            return true; 
        } else {
            alert('The File APIs are not fully supported by your browser. Fallback required.');
            return false;
        }
    }

    /**
     * read text input
     */
    function readText(filePath) {
        var output = ""; //placeholder for text output
        if(filePath.files && filePath.files[0]) {           
            reader.onload = function (e) {
                output = e.target.result;
                displayContents(output);
            };//end onload()
            reader.readAsText(filePath.files[0]);
        }//end if html5 filelist support
        else if(ActiveXObject && filePath) { //fallback to IE 6-8 support via ActiveX
            try {
                reader = new ActiveXObject("Scripting.FileSystemObject");
                var file = reader.OpenTextFile(filePath, 1); //ActiveX File Object
                output = file.ReadAll(); //text contents of file
                file.Close(); //close file "input stream"
                displayContents(output);
            } catch (e) {
                if (e.number == -2146827859) {
                    alert('Unable to access local files due to browser security settings. ' + 
                     'To overcome this, go to Tools->Internet Options->Security->Custom Level. ' + 
                     'Find the setting for "Initialize and script ActiveX controls not marked as safe" and change it to "Enable" or "Prompt"'); 
                }
            }       
        }
        else { //this is where you could fallback to Java Applet, Flash or similar
            return false;
        }       
        return true;
    }   

    /**
     * display content using a basic HTML replacement
     */
    function displayContents(txt) {
        var el = document.getElementById('main'); 
        el.innerHTML = txt; //display output in DOM
    }   
</script>
</head>
<body onload="checkFileAPI();">
    <div id="container">    
        <input type="file" onchange='readText(this)' />
        <br/>
        <hr/>   
        <h3>Contents of the Text file:</h3>
        <div id="main">
            ...
        </div>
    </div>
</body>
</html>

It's also possible to do the same thing to support some older versions of IE (I think 6-8) using the ActiveX Object, I had some old code which does that too but its been a while so I'll have to dig it up I've found a solution similar to the one I used courtesy of Jacky Cui's blog and edited this answer (also cleaned up code a bit). Hope it helps.

Lastly, I just read some other answers that beat me to the draw, but as they suggest, you might be looking for code that lets you load a text file from the server (or device) where the JavaScript file is sitting. If that's the case then you want AJAX code to load the document dynamically which would be something as follows:

<!DOCTYPE html>
<html>
<head><meta charset="utf-8" />
<title>Read File (via AJAX)</title>
<script type="text/javascript">
var reader = new XMLHttpRequest() || new ActiveXObject('MSXML2.XMLHTTP');

function loadFile() {
    reader.open('get', 'test.txt', true); 
    reader.onreadystatechange = displayContents;
    reader.send(null);
}

function displayContents() {
    if(reader.readyState==4) {
        var el = document.getElementById('main');
        el.innerHTML = reader.responseText;
    }
}

</script>
</head>
<body>
<div id="container">
    <input type="button" value="test.txt"  onclick="loadFile()" />
    <div id="main">
    </div>
</div>
</body>
</html>

Yet another way of doing this in Javascript using inline onclick, IIFE, event and preventDefault():

<a href='#' onclick="(function(e){e.preventDefault();})(event)">Click Me</a>

Objective-C - [RLMRealmConfiguration defaultConfiguration].fileURL

NSLog(@"%@",[RLMRealmConfiguration defaultConfiguration].fileURL);

Eg-/Users/"Your-user-name"/Library/Developer/CoreSimulator/Devices/E58645FF-90DE-434D-B2EB-FA145EB6F2EA/data/Containers/Data/Application/E427BD21-2CB1-4F64-9ADF-8742FF731209/Documents/

This is the simplest command you can run to get your path to .realm file. You will see the .realm file after all your read and write operations are completed.

Or

You can you open source openSim, alternative of simpholders to access your app’s documents directory directly from your menu bar

This problem isn't caused by missing tab stops; it's that emacs has a (new?) tab method called indent-relative that seems designed to line up tabular data. The TAB key is mapped to the method indent-for-tab-command, which calls whatever method the variable indent-line-function is set to, which is indent-relative method for text mode. I havn't figured out a good way to override the indent-line-function variable (text mode hook isn't working, so maybe it is getting reset after the mode-hooks run?) but one simple way to get rid of this behavior is to just chuck the intent-for-tab-command method by setting TAB to the simpler tab-to-tab-stop method:

(define-key text-mode-map (kbd "TAB") 'tab-to-tab-stop)

An argument can be made for adding the space programmatically. Since these cases will be often used in concatenations, I decided to stop the madness and just do the old + " " +. These will make sense in most European languages, I would gather.

Simplest way is:

bgSound = new Audio("sounds/background.mp3");
bgSound.loop = true;
bgSound.play();

        private void btnfilebrowse_Click(object sender, EventArgs e)
        {
            OpenFileDialog dlg = new OpenFileDialog();
            //dlg.ShowDialog();
            dlg.Filter = "CSV files (*.csv)|*.csv|XML files (*.xml)|*.xml";
            if (dlg.ShowDialog() == DialogResult.OK)
            {
                string fileName;
                fileName = dlg.FileName;
                string filecopy;
                filecopy = dlg.FileName;
                filecopy = Path.GetFileName(filecopy);
                string strFilename;
                strFilename = filecopy;
                 strFilename = strFilename.Substring(0, strFilename.LastIndexOf('.'));
                //fileName = Path.GetFileName(fileName);             

                txtfilepath.Text = strFilename;

                string filedest = System.IO.Path.GetFullPath(".\\Excels_Read\\'"+txtfilepath.Text+"'.csv");
               // filedest = "C:\\Users\\adm\\Documents\\Visual Studio 2010\\Projects\\ConvertFile\\ConvertFile\\Excels_Read";
                FileInfo file = new FileInfo(fileName);
                file.CopyTo(filedest);
             // File.Copy(fileName, filedest,true);
                MessageBox.Show("Import Done!!!");
            }
        }

Tackling this task, I'd first find the number of decimal places in x, then round y accordingly. I'd use:

y.toFixed(x.toString().split(".")[1].length);

It should convert x to a string, split it over the decimal point, find the length of the right part, and then y.toFixed(length) should round y based on that length.

You can use Google Cloud Messaging or GCM, it's free and easy to use. Also you can use third party push servers like PushWoosh which gives you more flexibility

A working JSFIDDLE

You can do something like this:

var y = [1, 2, 2, 3, 2]
var removeItem = 2;

y = jQuery.grep(y, function(value) {
  return value != removeItem;
});

Result:

[1, 3]

ALTER TABLE `ALLITEMS`
    CHANGE COLUMN `itemid` `itemid` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT;

1. start up the command prompt (CMD) with administrator rights.
2. Type c:\windows\microsoft.net\framework\v4.0.30319\installutil.exe [your windows service path to exe]
3. Press return

System.Diagnostics.Stopwatch is designed for this task.

A simple way of doing this is via nargin (N arguments in). The downside is you have to make sure that your argument list and the nargin checks match.

It is worth remembering that all inputs are optional, but the functions will exit with an error if it calls a variable which is not set. The following example sets defaults for b and c. Will exit if a is not present.

function [ output_args ] = input_example( a, b, c )
if nargin < 1
  error('input_example :  a is a required input')
end

if nargin < 2
  b = 20
end

if nargin < 3
  c = 30
end
end

This does work for me. In below example, Alpha range can be a value between 0 to 255. Previously, I made a mistake by thinking that it must be a value of percentage.

Dim x as integer = 230 Panel1.BackColor = Color.FromArgb(x, Color.Blue)

This is a simple example

COUNTER=1
for i in {1..5}
do   
   echo $COUNTER;
   //echo "Welcome $i times"
   ((COUNTER++));    
done

i know a way ny which you can call you private function to test in mockito

@Test
    public  void  commandEndHandlerTest() throws  Exception
    {
        Method retryClientDetail_privateMethod =yourclass.class.getDeclaredMethod("Your_function_name",null);
        retryClientDetail_privateMethod.setAccessible(true);
        retryClientDetail_privateMethod.invoke(yourclass.class, null);
    }

I use Visual Studio 2013. I faced this problem 2 times:

1. On first occasion, I was running Visual Studio without Administrator rights. So, I closed VS and started it using 'Run as administrator' option. This solved my problem.

2. On second occasion, I restarted VS many times, every time making sure that I am running it as an administrator. Also, I rebuilt solution many times. But, in spite of that I was getting error. After that, I removed the concerned file from the target location (the file was already present may be from the previous build at the location where it tries to copy to) and rebuilt the solution. After that, error went away and everything ran smoothly!

I've found a definition that says that Layers are a logical separation and tiers are a physical separation.

Two options:

1. Use the LIKE keyword, along with percent signs in the string

   select * from table where field like '%a%' or field like '%b%'.
   

   (note: If your search string contains percent signs, you'll need to escape them)

2. If you're looking for more a complex combination of strings than you've specified in your example, you could regular expressions (regex):

   See the MySQL manual for more on how to use them: http://dev.mysql.com/doc/refman/5.1/en/regexp.html

Of these, using LIKE is the most usual solution -- it's standard SQL, and in common use. Regex is less commonly used but much more powerful.

Note that whichever option you go with, you need to be aware of possible performance implications. Searching for sub-strings like this will mean that the query will have to scan the entire table. If you have a large table, this could make for a very slow query, and no amount of indexing is going to help.

If this is an issue for you, and you'r going to need to search for the same things over and over, you may prefer to do something like adding a flag field to the table which specifies that the string field contains the relevant sub-strings. If you keep this flag field up-to-date when you insert of update a record, you could simply query the flag when you want to search. This can be indexed, and would make your query much much quicker. Whether it's worth the effort to do that is up to you, it'll depend on how bad the performance is using LIKE.

Replace (.*")\d+(")

With $1x$2

Where x is your "value inside scopes".

If you are using the Spring Framework, the most straightforward way to do this is:

private Integer laancNotifyPort = SocketUtils.findAvailableTcpPort();

You can also set an acceptable range, and it will search in this range:

private Integer laancNotifyPort = SocketUtils.findAvailableTcpPort(9090, 10090);

This is a convenience method that abstracts away the complexity but internally is similar to a lot of the other answers on this thread.

OAuth(Open Authorization) is an open standard for access granting/deligation protocol. It used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords. It does not deal with authentication.

Or

OAuth 2.0 is a protocol that allows a user to grant limited access to their resources on one site, to another site, without having to expose their credentials.

• Analogy 1: Many luxury cars today come with a valet key. It is a special key you give the parking attendant and unlike your regular key, will not allow the car to drive more than a mile or two. Some valet keys will not open the trunk, while others will block access to your onboard cell phone address book. Regardless of what restrictions the valet key imposes, the idea is very clever. You give someone limited access to your car with a special key, while using your regular key to unlock everything. src from auth0

• Analogy 2: Assume, we want to fill an application form for a bank account. Here Oauth works as, instead of filling the form by applicant, bank can fill the form using Adhaar or passport.

  Here the following three entities are involved:

  1. Applicant i.e. Owner
  2. Bank Account is OAuth Client, they need information
  3. Adhaar/Passport ID is OAuth Provider

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:

http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• http://www.mssqltips.com/sqlservertip/2632/checking-for-potential-constraint-violations-before-entering-sql-server-try-and-catch-logic/
• http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling

Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.

I've written a complement to the accepted answer. In case someone, like myself need a prefixed version of the keys, this can be helpful.

Array

    [root] => Array
        (
            [url] => http://localhost/misc/markia
        )

)

<?php
function flattenOptions($array, $old = '') {

    return FALSE;
  }
  $result = array();
  foreach ($array as $key => $value) {
    if (is_array($value)) {
      $result = array_merge($result, flattenOptions($value, $key));
    }

Yes, you can.

this.formGroup.get('name of you control').value

Your regex should be something like

[0-9\-\(\)\s]+.

It matches numbers, dashes, parentheses and space.

If you need something more strict, matching just your example, try this:

([0-9]{10})|(\([0-9]{3}\)\s+[0-9]{3}\-[0-9]{4})

A random value?

If you want a random value, try

<?php
$value = mt_rand($min, $max);

mt_rand() will run a bit more random if you are using many random numbers in a row, or if you might ever execute the script more than once a second. In general, you should use mt_rand() over rand() if there is any doubt.

When I had the same problem I fixed it by deleting the existing key.snk in that project and adding a new key.

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

I faced this issue because my $(elem).click(function(){}); script was placed inline in a div that was set to style="display:none;".

When the css display was switched to block, the script would add the event listener a second time. I moved the script to a separate .js file and the duplicate event listener was no longer initiated.

  String s = "ABC[This is to extract]";

    System.out.println(s);
    int startIndex = s.indexOf('[');
    System.out.println("indexOf([) = " + startIndex);
    int endIndex = s.indexOf(']');
    System.out.println("indexOf(]) = " + endIndex);
    System.out.println(s.substring(startIndex + 1, endIndex));

I have used Mockito.verify in this way

@UnitTest
public class JUnitServiceTest
{
    @Mock
    private MyCustomService myCustomService;


    @Test
    public void testVerifyMethod()
    {
       Mockito.verify(myCustomService, Mockito.never()).mymethod(parameters); // method will never call (an alternative can be pick to use times(0))
       Mockito.verify(myCustomService, Mockito.times(2)).mymethod(parameters); // method will call for 2 times
       Mockito.verify(myCustomService, Mockito.atLeastOnce()).mymethod(parameters); // method will call atleast 1 time
       Mockito.verify(myCustomService, Mockito.atLeast(2)).mymethod(parameters); // method will call atleast 2 times
       Mockito.verify(myCustomService, Mockito.atMost(3)).mymethod(parameters); // method will call at most 3 times
       Mockito.verify(myCustomService, Mockito.only()).mymethod(parameters); //   no other method called except this
    }
}

Using ios_base::sync_with_stdio(false); is sufficient to decouple the C and C++ streams. You can find a discussion of this in Standard C++ IOStreams and Locales, by Langer and Kreft. They note that how this works is implementation-defined.

The cin.tie(NULL) call seems to be requesting a decoupling between the activities on cin and cout. I can't explain why using this with the other optimization should cause a crash. As noted, the link you supplied is bad, so no speculation here.

The easiest solution to make Angular 2+ application served from Amazon S3 and direct URLs working is to specify index.html both as Index and Error documents in S3 bucket configuration.

To start, Joe Kington's answer provides very good advice using a gui-neutral approach, and you should definitely take his advice (especially about Blitting) and put it into practice. More info on this approach, read the Matplotlib Cookbook

However, the non-GUI-neutral (GUI-biased?) approach is key to speeding up the plotting. In other words, the backend is extremely important to plot speed.

Put these two lines before you import anything else from matplotlib:

import matplotlib
matplotlib.use('GTKAgg') 

Of course, there are various options to use instead of GTKAgg, but according to the cookbook mentioned before, this was the fastest. See the link about backends for more options.

If you using ajax to load modal's body such way and want to be able to reload it's content

<a data-toggle="modal" data-target="#myModal" href="./add">Add</a>
<a data-toggle="modal" data-target="#myModal" href="./edit/id">Modify</a>

<div id="myModal" class="modal fade">
    <div class="modal-dialog">
        <div class="modal-content">
            <!-- Content will be loaded here -->
        </div>
    </div>
</div>

use

<script>
    $(function() {
        $('.modal').on('hidden.bs.modal', function(){
            $(this).removeData('bs.modal');
        });
    });
</script>

As answered in the official Python FAQ:

b = a[:]

Usually, git creates a hidden directory in project's root directory (.git/)

When you're working on a CMS, its possible you install modules/plugins carrying .git/ directory with git's metadata for the specific module/plugin

Quickest solution is to find all .git directories and keep only your root git metadata directory. If you do so, git will not consider those modules as project submodules.

We can add swap space in any server

create a file using dd command

 #dd if=/dev/zero of=/swapfile bs=1M count=2048
                    or
 #dd if=/dev/zero of=/swapfile bs=1024M count=2

bs is blocksize and count refers to the size in MB or GB

we can use vice versa

After creation change the permission of file :

 #chmod 600 /swapfile 

Then makeswap the file :

 #mkswap /swapfile 

Then enable the swap file with swapon command :

 #swapon  /swapfile 

Check with free command whether swap is enabled or not :

 #free -h
 #swapon -s

As with many questions, the answer is - It depends.

You should be very careful when handling large amounts of data on the front end. On top of making your front end feel sluggish, Firestore also charges you $0.60 per million reads you make.

Small collection (less than 100 documents)

Use with care - Frontend user experience may take a hit

Handling this on the front end should be fine as long as you are not doing too much logic with this returned array.

db.collection('...').get().then(snap => {
   size = snap.size // will return the collection size
});

Medium collection (100 to 1000 documents)

Use with care - Firestore read invocations may cost a lot

Handling this on the front end is not feasible as it has too much potential to slow down the users system. We should handle this logic server side and only return the size.

The drawback to this method is you are still invoking firestore reads (equal to the size of your collection), which in the long run may end up costing you more than expected.

Cloud Function:

...
db.collection('...').get().then(snap => {
    res.status(200).send({length: snap.size});
});

Front End:

yourHttpClient.post(yourCloudFunctionUrl).toPromise().then(snap => {
     size = snap.length // will return the collection size
})

Large collection (1000+ documents)

Most scalable solution

FieldValue.increment()

As of April 2019 Firestore now allows incrementing counters, completely atomically, and without reading the data prior. This ensures we have correct counter values even when updating from multiple sources simultaneously (previously solved using transactions), while also reducing the number of database reads we perform.

By listening to any document deletes or creates we can add to or remove from a count field that is sitting in the database.

See the firestore docs - Distributed Counters Or have a look at Data Aggregation by Jeff Delaney. His guides are truly fantastic for anyone using AngularFire but his lessons should carry over to other frameworks as well.

Cloud Function:

export const documentWriteListener = 
    functions.firestore.document('collection/{documentUid}')
    .onWrite((change, context) => {

    if (!change.before.exists) {
        // New document Created : add one to count

        db.doc(docRef).update({numberOfDocs: FieldValue.increment(1)});
    
    } else if (change.before.exists && change.after.exists) {
        // Updating existing document : Do nothing

    } else if (!change.after.exists) {
        // Deleting document : subtract one from count

        db.doc(docRef).update({numberOfDocs: FieldValue.increment(-1)});

    }

return;
});

Now on the frontend you can just query this numberOfDocs field to get the size of the collection.

Replace the * with a /

So instead of

COPY * <destination>

use

COPY / <destination>

You should not play with the height. Let the text field determine the height based on the font used.

If you want to control the width of the text field then you can use

textField.setColumns(...);

to let the text field determine the preferred width.

Or if you want the width to be the entire width of the parent panel then you need to use an appropriate layout. Maybe the NORTH of a BorderLayout.

See the Swing tutorial on Layout Managers for more information.

The includes() method determines whether one string may be found within another string, returning true or false as appropriate.

Syntax :-string.includes(searchString[, position])

searchString:-A string to be searched for within this string.

position:-Optional. The position in this string at which to begin searching for searchString; defaults to 0.

string = 'LOL';
console.log(string.includes('lol')); // returns false 
console.log(string.includes('LOL')); // returns true 

Instead of show, try to use CSS to hide and show the content.

function switch_tabs(obj) {
    $('.tab-content').css('display', 'none'); // you could still use `.hide()` here
    $('.tabs a').removeClass("selected");
    var id = obj.attr("rel");

    $('#' + id).css('display', 'inline-block');
    obj.addClass("selected");
}

To use base_url() (shorthand), you have to load the URL Helper first

$this->load->helper('url');

Or you can autoload it by changing application/config/autoload.php

Or just use

$this->config->base_url();

Same applies to site_url().

Also I can see you are missing echo (though its not your current problem), use the code below to solve the problem

<link rel="stylesheet" href="<?php echo base_url(); ?>css/default.css" type="text/css" />

We're doing this to create thumbnails of images:

  BufferedImage tThumbImage = new BufferedImage( tThumbWidth, tThumbHeight, BufferedImage.TYPE_INT_RGB );
  Graphics2D tGraphics2D = tThumbImage.createGraphics(); //create a graphics object to paint to
  tGraphics2D.setBackground( Color.WHITE );
  tGraphics2D.setPaint( Color.WHITE );
  tGraphics2D.fillRect( 0, 0, tThumbWidth, tThumbHeight );
  tGraphics2D.setRenderingHint( RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR );
  tGraphics2D.drawImage( tOriginalImage, 0, 0, tThumbWidth, tThumbHeight, null ); //draw the image scaled

  ImageIO.write( tThumbImage, "JPG", tThumbnailTarget ); //write the image to a file

Above answers are bit old.

Firstly create a key-pair and then attach it to Elastic Beanstalk environment.

Steps to create a key-pair

1. Login to AWS
2. Services -> EC2
3. In left under NETWORK & SECURITY select key pairs
4. Select Create new Key Pair, type key name and click on create. The key will be automatically downloaded to your system.

Steps to attach created key pair to Elastic Beanstalk environment

1. AWS -> Services -> Elastic Beanstalk

2. Select your environment and click on the configuration in left.

3. In Configuration overview select modify from Security.

4. Under Virtual machine permissions select key-pair that we created.

5. Click on save and then on save configuration.

This will take some time to reflect to your EC2 instance.

If this is all the object is going to store, then best literal would be

var top_brands = {
    'Adidas' : 100,
    'Nike'   : 50
    };

Then all you need is a for...in loop.

for (var key in top_brands){
    console.log(key, top_brands[key]);
    }

try

std::fill

and also

std::size siz = vec.size();
//no memory allocating
vec.resize(0);
vec.resize(siz, 0);

None of these answers with the use of HEAD@{1} worked out for me, so here's my solution:

git reflog

d0c9f22 HEAD@{0}: commit (amend): [Feature] - ABC Commit Description 
c296452 HEAD@{1}: commit: [Feature] - ABC Commit Description 

git reset --soft c296452

Your staging environment will now contain all of the changes that you accidentally merged with the c296452 commit.

If you want a list of only the object columns you could do:

non_numerics = [x for x in df.columns \
                if not (df[x].dtype == np.float64 \
                        or df[x].dtype == np.int64)]

and then if you want to get another list of only the numerics:

numerics = [x for x in df.columns if x not in non_numerics]

def digits(n)
    count = 0
    if n == 0:
        return 1
    
    if n < 0:
        n *= -1

    while (n >= 10**count):
        count += 1
        n += n%10

    return count

print(digits(25))   # Should print 2
print(digits(144))  # Should print 3
print(digits(1000)) # Should print 4
print(digits(0))    # Should print 1

You can also do this with linq if you'd like

var names = new List<string>() { "John", "Anna", "Monica" };
var joinedNames = names.Aggregate((a, b) => a + ", " + b);

Although I prefer the non-linq syntax in Quartermeister's answer and I think Aggregate might perform slower (probably more string concatenation operations).

Try this, but you can adjust frame size with bounds and edit title.

package co.form.Try;

import javax.swing.JFrame;

public class Form {

    public static void main(String[] args) {
        JFrame obj =new JFrame();
        obj.setBounds(10,10,700,600); 
        obj.setTitle("Application Form");
        obj.setResizable(false);                
        obj.setVisible(true);       
        obj.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

}

This error occurs because of missing some files and the main reason is "Composer"

First Run these commands in CMD

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === 'e0012edf3e80b6978849f5eff0d4b4e4c79ff1609dd1e613307e16318854d24ae64f26d17af3ef0bf7cfb710ca74755a') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

Then Create a New project
Example:

D:/Laravel_Projects/New_Project
laravel new New_Project

After that start the server using

php artisan serve

With many files and many cores, fread xargs cat (described below) is about 50x faster than the fastest solution in the top 3 answers.

rbindlist lapply read.delim  500s <- 1st place & accepted answer
rbindlist lapply fread       250s <- 2nd & 3rd place answers
rbindlist mclapply fread      10s
fread xargs cat                5s

Time to read 121401 csvs into a single data.table. Each time is an average of three runs then rounded. Each csv has 3 columns, one header row, and, on average, 4.510 rows. Machine is a GCP VM with 96 cores.

The top three answers by @A5C1D2H2I1M1N2O1R2T1, @leerssej, and @marbel and are all essentially the same: apply fread (or read.delim) to each file, then rbind/rbindlist the resulting data.tables. I usually use the rbindlist(lapply(list.files("*.csv"),fread)) form.

This is better than other R-internal alternatives, and fine for a small number of large csvs, but not the best for a large number of small csvs when speed matters. In that case, it can be much faster to first use cat, as @Spacedman suggests in the 4th-ranked answer. I'll add some detail on how to do this from within R:

x = fread(cmd='cat *.csv', header=F)

However, what if each csv has a header?

x = fread(cmd="awk 'NR==1||FNR!=1' *.csv", header=T)

And what if you have so many files that the *.csv shell glob fails?

x = fread(cmd='find . -name "*.csv" | xargs cat', header=F)

And what if all files have a header AND there are too many files?

header = fread(cmd='find . -name "*.csv" | head -n1 | xargs head -n1', header=T)
x = fread(cmd='find . -name "*.csv" | xargs tail -q -n+2', header=F)
names(x) = names(header)

And what if the resulting concatenated csv is too big for system memory?

system('find . -name "*.csv" | xargs cat > combined.csv')
x = fread('combined.csv', header=F)

With headers?

system('find . -name "*.csv" | head -n1 | xargs head -n1 > combined.csv')
system('find . -name "*.csv" | xargs tail -q -n+2 >> combined.csv')
x = fread('combined.csv', header=T)

Finally, what if you don't want all .csv in a directory, but rather a specific set of files? (Also, they all have headers.) (This is my use case.)

fread(text=paste0(system("xargs cat|awk 'NR==1||$1!=\"<column one name>\"'",input=paths,intern=T),collapse="\n"),header=T,sep="\t")

and this is about the same speed as plain fread xargs cat :)

Note: for data.table pre-v1.11.6 (19 Sep 2018), omit the cmd= from fread(cmd=.

Addendum: using the parallel library's mclapply in place of serial lapply, e.g., rbindlist(lapply(list.files("*.csv"),fread)) is also much faster than rbindlist lapply fread.

To sum up, if you're interested in speed, and have many files and many cores, fread xargs cat is about 50x faster than the fastest solution in the top 3 answers.

there's no problem - everything works as expected.

In GitLab some branches can be protected. By default only Maintainer/Owner users can commit to protected branches (see permissions docs). master branch is protected by default - it forces developers to issue merge requests to be validated by project maintainers before integrating them into main code.

You can turn on and off protection on selected branches in Project Settings (where exactly depends on GitLab version - see instructions below).

On the same settings page you can also allow developers to push into the protected branches. With this setting on, protection will be limited to rejecting operations requiring git push --force (rebase etc.)

Since GitLab 9.3

Go to project: "Settings" ? "Repository" ? "Expand" on "Protected branches"

I'm not really sure when this change was introduced, screenshots are from 10.3 version.

Now you can select who is allowed to merge or push into selected branches (for example: you can turn off pushes to master at all, forcing all changes to branch to be made via Merge Requests). Or you can click "Unprotect" to completely remove protection from branch.

Since GitLab 9.0

Similarly to GitLab 9.3, but no need to click "Expand" - everything is already expanded:

Go to project: "Settings" ? "Repository" ? scroll down to "Protected branches".

Pre GitLab 9.0

Project: "Settings" ? "Protected branches" (if you are at least 'Master' of given project).

Then click on "Unprotect" or "Developers can push":

I haven't seen a JavaScript answer without jQuery. Hopefully it helps someone.

var elements = document.querySelectorAll('[data-customerID="22"]');_x000D_

<a data-customerID='22'>test</a>

Info:

• data attributes

• .querySelectorAll();

• Download maven compiler plugin jar from your central repositoy n try
• If it is still failing check your jdk version, it is because of your application is built on diff jdk version

You can achieve that by printing your string like:
