yourTextView.setText(String.format("Value of a: %.2f", a));

the getText method returns a String, while the setText receives a String, so you can write it like label1.setText(nameField.getText()); in your listener.

To test only the IMagick PHP extension (not the full ImageMagick suite), save the following as a PHP file (testImagick.php) and then run it from console: php testImagick.php

<?php
$image = new Imagick();
$image->newImage(1, 1, new ImagickPixel('#ffffff'));
$image->setImageFormat('png');
$pngData = $image->getImagesBlob();
echo strpos($pngData, "\x89PNG\r\n\x1a\n") === 0 ? 'Ok' : 'Failed';
echo "\n";

You can use this:

Map<String, String> map = new HashMap<>();

props.forEach((key, value) -> map.put(key.toString(), value.toString()));

This is the simplest way to do it. CSS only.

1. add width to the ul element.
2. add display:inline-block and width of the new column (should be less than half of the ul width).

ul.list {_x000D_
  width: 300px;  _x000D_
}_x000D_
_x000D_
ul.list li{_x000D_
  display:inline-block;_x000D_
  width: 100px;_x000D_
}

<ul class="list">_x000D_
    <li>A</li>_x000D_
    <li>B</li>_x000D_
    <li>C</li>_x000D_
    <li>D</li>_x000D_
    <li>E</li>_x000D_
</ul>

This code have one problem:

int latitude = (int) (location.getLatitude());
int longitude = (int) (location.getLongitude());

You can change int to double

double latitude = location.getLatitude();
double longitude = location.getLongitude();

I personally avoid else blocks when possible. See the Anti-if Campaign

Also, they don't charge 'extra' for the line, you know :p

I'm aware this question was asked over two years ago, but for any recent viewers, here's an alternative solution, which has a few advantages over Marc-François's solution:

div {
    height: 50px;
    border: 1px solid blue;
    line-height: 50px;
}

Here we simply only add a line-height equal to that of the height of the div. The advantage being you can now change the display property of the div as you see fit, to inline-block for instance, and it's contents will remain vertically centered. The accepted solution requires you treat the div as a table cell. This should work perfectly, cross-browser.

The only other advantage being it's just one more CSS rule instead of two :)

Cheers!

You will need wrapper classes:

public class SomeIntInfo
{
    [XmlAttribute]
    public int Value { get; set; }
}

public class SomeStringInfo
{
    [XmlAttribute]
    public string Value { get; set; }
}

public class SomeModel
{
    [XmlElement("SomeStringElementName")]
    public SomeStringInfo SomeString { get; set; }

    [XmlElement("SomeInfoElementName")]
    public SomeIntInfo SomeInfo { get; set; }
}

or a more generic approach if you prefer:

public class SomeInfo<T>
{
    [XmlAttribute]
    public T Value { get; set; }
}

public class SomeModel
{
    [XmlElement("SomeStringElementName")]
    public SomeInfo<string> SomeString { get; set; }

    [XmlElement("SomeInfoElementName")]
    public SomeInfo<int> SomeInfo { get; set; }
}

And then:

class Program
{
    static void Main()
    {
        var model = new SomeModel
        {
            SomeString = new SomeInfo<string> { Value = "testData" },
            SomeInfo = new SomeInfo<int> { Value = 5 }
        };
        var serializer = new XmlSerializer(model.GetType());
        serializer.Serialize(Console.Out, model);
    }
}

will produce:

<?xml version="1.0" encoding="ibm850"?>
<SomeModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <SomeStringElementName Value="testData" />
  <SomeInfoElementName Value="5" />
</SomeModel>

We recently experienced this on a WinPhone 8 project, in VS 2012 Update 2.

Inexplicably, the cause was using the Tuple type. Removing the code that used a Tuple the problem went away. Add the code back the problem returned.

Probably, a better and more functional way is to wrap exceptions and propagate them further in the stream. Take a look at the Try type of Vavr for example.

Example:

interface CheckedFunction<I, O> {
    O apply(I i) throws Exception; }

static <I, O> Function<I, O> unchecked(CheckedFunction<I, O> f) {
    return i -> {
        try {
            return f.apply(i);
        } catch(Exception ex) {

            throw new RuntimeException(ex);
        }
    } }

fileNamesToRead.map(unchecked(file -> Files.readAllLines(file)))

OR

@SuppressWarnings("unchecked")
private static <T, E extends Exception> T throwUnchecked(Exception e) throws E {
    throw (E) e;
}

static <I, O> Function<I, O> unchecked(CheckedFunction<I, O> f) {
    return arg -> {
        try {
            return f.apply(arg);
        } catch(Exception ex) {
            return throwUnchecked(ex);
        }
    };
}

2nd implementation avoids wrapping the exception in a RuntimeException. throwUnchecked works because almost always all generic exceptions are treated as unchecked in java.

No need to use date_default_timezone_set for the whole script, just specify the timezone you want with a DateTime object:

$now = new DateTime(null, new DateTimeZone('America/New_York'));
$now->setTimezone(new DateTimeZone('Europe/London'));    // Another way
echo $now->format("Y-m-d\TH:i:sO"); // something like "2015-02-11T06:16:47+0100" (ISO 8601)

Any unit test you could create by just pressing a button would not be worth anything. How is the tool to know what parameters to pass your method and what to expect back? Unless I'm misunderstanding your expectations.

Close to that is something like FitNesse, where you can set up tests, then separately you set up a wiki page with your test data, and it runs the tests with that data, publishing the results as red/greens.

If you would be happy to make test writing much faster, I would suggest Mockito, a mocking framework that lets you very easily mock the classes around the one you're testing, so there's less setup/teardown, and you know you're really testing that one class instead of a dependent of it.

You can get the parameters you are asking for by typing:

dir /?

For the full list, try:

dir /s /b /a:d

There is none. Alas, you have to type out the full type name.

Edit: 7 years after being posted, type inference for local variables (with var) was added in Java 10.

Edit: 6 years after being posted, to collect some of the comments from below:

• The reason C# has the var keyword is because it's possible to have Types that have no name in .NET. Eg:

  var myData = new { a = 1, b = "2" };
  

  In this case, it would be impossible to give a proper type to myData. 6 years ago, this was impossible in Java (all Types had names, even if they were extremely verbose and unweildy). I do not know if this has changed in the mean time.

• var is not the same as dynamic. variables are still 100% statically typed. This will not compile:

  var myString = "foo";
  myString = 3;
  

• var is also useful when the type is obvious from context. For example:

  var currentUser = User.GetCurrent();
  

  I can say that in any code that I am responsible for, currentUser has a User or derived class in it. Obviously, if your implementation of User.GetCurrent return an int, then maybe this is a detriment to you.

• This has nothing to do with var, but if you have weird inheritance hierarchies where you shadow methods with other methods (eg new public void DoAThing()), don't forget that non-virtual methods are affected by the Type they are cast as.

  I can't imagine a real world scenario where this is indicative of good design, but this may not work as you expect:

  class Foo {
      public void Non() {}
      public virtual void Virt() {}
  }
  
  class Bar : Foo {
      public new void Non() {}
      public override void Virt() {}
  }
  
  class Baz {
      public static Foo GetFoo() {
          return new Bar();
      }
  }
  
  var foo = Baz.GetFoo();
  foo.Non();  // <- Foo.Non, not Bar.Non
  foo.Virt(); // <- Bar.Virt
  
  var bar = (Bar)foo;
  bar.Non();  // <- Bar.Non, not Foo.Non
  bar.Virt(); // <- Still Bar.Virt
  

  As indicated, virtual methods are not affected by this.

• No, there is no non-clumsy way to initialize a var without an actual variable.

  var foo1 = "bar";        //good
  var foo2;                //bad, what type?
  var foo3 = null;         //bad, null doesn't have a type
  var foo4 = default(var); //what?
  var foo5 = (object)null; //legal, but go home, you're drunk
  

  In this case, just do it the old fashioned way:

  object foo6;
  

Any one can try this command to truncate any file in linux system

This will surely work in any format :

truncate -s 0 file.txt

What did work for me (inspired from aax' thanks) :

Paste this into /Library/LaunchDaemons/com.apple.launchd.limit.plist then reboot :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
  <plist version="1.0">
  <dict>
  <key>Label</key>
  <string>eicar</string>
  <key>ProgramArguments</key>
  <array>
    <string>/bin/launchctl</string>
    <string>limit</string>
    <string>maxfiles</string>
    <string>16384</string>
    <string>16384</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>ServiceIPC</key>
  <false/>
</dict>
</plist>

If you need it step by step :

• Launch terminal
• Type sudo su then enter your password to log in as root
• Type vi /Library/LaunchDaemons/com.apple.launchd.limit.plist
• When into the vi editor, press the key i to enter insert mode then paste the exact code content above (?+v). This will force the limit to 16384 files per process and 16384 files total
• Save your file and quit using esc then :wq
• Reboot your system, and check that it is working using the command launchctl limit

I hope this helped you.

According to the settings reference:

updatePolicy: This element specifies how often updates should attempt to occur. Maven will compare the local POM’s timestamp (stored in a repository’s maven-metadata file) to the remote. The choices are: always, daily (default), interval:X (where X is an integer in minutes) or never.

Example:

<profiles>
    <profile>
      ...
      <repositories>
        <repository>
          <id>myRepo</id>
          <name>My Repository</name>
          <releases>
            <enabled>false</enabled>
            <updatePolicy>always</updatePolicy>
            <checksumPolicy>warn</checksumPolicy>
          </releases>
         </repository>
      </repositories>
      ...

for removing the disabled properties

 $('#inputDisabled').removeAttr('Disabled');

for adding the disabled properties

 $('#inputDisabled').attr('disabled', 'disabled' );

css is enough :

width : desired_width;

Check your JAVA_HOME path. As systems looks for a java.policy file which is located in JAVA_HOME/jre/lib/security. Your JAVA_HOME should always be ../JAVA/JDK.

Use is_int($var)

Here is tutorial about is_int()

For-loops:

For-loop in C:

for(int x = 0; x<=3; x++)
{
    //Do something!
}

The same loop in 8086 assembler:

        xor cx,cx   ; cx-register is the counter, set to 0
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        inc cx      ; Increment
        cmp cx,3    ; Compare cx to the limit
        jle loop1   ; Loop while less or equal

That is the loop if you need to access your index (cx). If you just wanna to something 0-3=4 times but you do not need the index, this would be easier:

        mov cx,4    ; 4 iterations
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        loop loop1  ; loop instruction decrements cx and jumps to label if not 0

If you just want to perform a very simple instruction a constant amount of times, you could also use an assembler-directive which will just hardcore that instruction

times 4 nop

Do-while-loops

Do-while-loop in C:

int x=1;
do{
    //Do something!
}
while(x==1)

The same loop in assembler:

        mov ax,1
loop1   nop         ; Whatever you wanna do goes here
        cmp ax,1    ; Check wether cx is 1
        je loop1    ; And loop if equal

While-loops

While-loop in C:

while(x==1){
    //Do something
}

The same loop in assembler:

        jmp loop1   ; Jump to condition first
cloop1  nop         ; Execute the content of the loop
loop1   cmp ax,1    ; Check the condition
        je cloop1   ; Jump to content of the loop if met

For the for-loops you should take the cx-register because it is pretty much standard. For the other loop conditions you can take a register of your liking. Of course replace the no-operation instruction with all the instructions you wanna perform in the loop.

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

If you don't have DBA rights then you can use user_segments table:

select bytes/1024/1024 MB from user_segments where segment_name='Table_name'

For the record, I think this is more of what he was looking for…

    UIBarButtonItem *l_backButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRewind target:self action:@selector(backToRootView:)];

    self.navigationItem.leftBarButtonItem = l_backButton;


    - (void) backToRootView:(id)sender {

        // Perform some custom code

        [self.navigationController popToRootViewControllerAnimated:YES];
    }

You can use the following method

 private function generateStringCondition($value = '',$field = '', $operator = '', $regex = '', $wildcardStart = '', $wildcardEnd = ''){
        if($value != ''){
            $where = " $field $regex '$wildcardStart".strtolower($value)."$wildcardEnd' ";

            $searchArray = explode(' ', $value);

            if(sizeof($searchArray) > 1){

                foreach ($searchArray as $key=>$value){
                    $where .="$operator $field $regex '$wildcardStart".strtolower($value)."$wildcardEnd'";
                }

            }

        }else{
            $where = '';
        }
        return $where;
    }

use this method like below

   $where =  $this->generateStringCondition($yourSearchString,  'LOWER(columnName)','or', 'like',  '%', '%');
  $sql = "select * from table $where";

I'm surprised no one has suggested using a result filter. This is the cleanest way to globally hook into the action/result pipeline:

public class JsonResultFilter : IResultFilter
{
    public int? MaxJsonLength { get; set; }

    public int? RecursionLimit { get; set; }

    public void OnResultExecuting(ResultExecutingContext filterContext)
    {
        if (filterContext.Result is JsonResult jsonResult)
        {
            // override properties only if they're not set
            jsonResult.MaxJsonLength = jsonResult.MaxJsonLength ?? MaxJsonLength;
            jsonResult.RecursionLimit = jsonResult.RecursionLimit ?? RecursionLimit;
        }
    }

    public void OnResultExecuted(ResultExecutedContext filterContext)
    {
    }
}

Then, register an instance of that class using GlobalFilters.Filters:

GlobalFilters.Filters.Add(new JsonResultFilter { MaxJsonLength = int.MaxValue });

Using new "Counter" class in collections module, based on lazyr's answer:

>>> import collections
>>> def duplicates(n): #n="123123123"
...     counter=collections.Counter(n) #{'1': 3, '3': 3, '2': 3}
...     dups=[i for i in counter if counter[i]!=1] #['1','3','2']
...     result={}
...     for item in dups:
...             result[item]=[i for i,j in enumerate(n) if j==item] 
...     return result
... 
>>> duplicates("123123123")
{'1': [0, 3, 6], '3': [2, 5, 8], '2': [1, 4, 7]}

Change

for (int cnt3 = 0 ; cnt3 <= integerList.FindLastIndex ; cnt3++)

to

for (int cnt3 = 0 ; cnt3 < integerList.Count; cnt3++)

I'm using an MVC / MVA design pattern, with multiple types of "views". One type is a "GuiView", which is a Tk window. I pass a view reference to my window object which does things like link buttons back to view functions (which the adapter / controller class also calls).

In order to do that, the view object constructor needed to be completed prior to creating the window object. After creating and displaying the window, I wanted to do some initial tasks with the view automatically. At first I tried doing them post mainloop(), but that didn't work because mainloop() blocked!

As such, I created the window object and used tk.update() to draw it. Then, I kicked off my initial tasks, and finally started the mainloop.

import Tkinter as tk

class Window(tk.Frame):
    def __init__(self, master=None, view=None ):
        tk.Frame.__init__( self, master )
        self.view_ = view       
        """ Setup window linking it to the view... """

class GuiView( MyViewSuperClass ):

    def open( self ):
        self.tkRoot_ = tk.Tk()
        self.window_ = Window( master=None, view=self )
        self.window_.pack()
        self.refresh()
        self.onOpen()
        self.tkRoot_.mainloop()         

    def onOpen( self ):        
        """ Do some initial tasks... """

    def refresh( self ):        
        self.tkRoot_.update()

$ brew tap caskroom/cask

Do this, it works:

    minSdkVersion 15
    targetSdkVersion 24

    multiDexEnabled true
}

Just use the below code to resolve this:

JsonObject obj = Json.createReader(new ByteArrayInputStream(Base64.getDecoder().decode(accessToken.split("\\.")[1].
                        replace('-', '+').replace('_', '/')))).readObject();

In the above code replace('-', '+').replace('_', '/') did the job. For more details see the https://jwt.io/js/jwt.js. I understood the problem from the part of the code got from that link:

function url_base64_decode(str) {
  var output = str.replace(/-/g, '+').replace(/_/g, '/');
  switch (output.length % 4) {
    case 0:
      break;
    case 2:
      output += '==';
      break;
    case 3:
      output += '=';
      break;
    default:
      throw 'Illegal base64url string!';
  }
  var result = window.atob(output); //polifyll https://github.com/davidchambers/Base64.js
  try{
    return decodeURIComponent(escape(result));
  } catch (err) {
    return result;
  }
}

Mongodb v3.4

You need to do the following to create a secure database:

Make sure the user starting the process has permissions and that the directories exist (/data/db in this case).

1) Start MongoDB without access control.

mongod --port 27017 --dbpath /data/db

2) Connect to the instance.

mongo --port 27017

3) Create the user administrator (in the admin authentication database).

use admin
db.createUser(
  {
    user: "myUserAdmin",
    pwd: "abc123",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)

4) Re-start the MongoDB instance with access control.

mongod --auth --port 27017 --dbpath /data/db

5) Connect and authenticate as the user administrator.

mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"

6) Create additional users as needed for your deployment (e.g. in the test authentication database).

use test
db.createUser(
  {
    user: "myTester",
    pwd: "xyz123",
    roles: [ { role: "readWrite", db: "test" },
             { role: "read", db: "reporting" } ]
  }
)

7) Connect and authenticate as myTester.

mongo --port 27017 -u "myTester" -p "xyz123" --authenticationDatabase "test"

I basically just explained the short version of the official docs here: https://docs.mongodb.com/master/tutorial/enable-authentication/

Yes you can. Just check my fiddle for clarification. For demo purpose i kept the code in fiddle at same location. You can extract that code as shown in two different Javascript files and load them in html file.

https://jsfiddle.net/mvora/mrLmkxmo/

 /******** PUT THIS CODE IN ONE JS FILE *******/

    var secondFileFuntion = function(){
        this.name = 'XYZ';
    }

    secondFileFuntion.prototype.getSurname = function(){
     return 'ABC';
    }


    var secondFileObject = new secondFileFuntion();

    /******** Till Here *******/

    /******** PUT THIS CODE IN SECOND JS FILE *******/

    function firstFileFunction(){
      var name = secondFileObject.name;
      var surname = secondFileObject.getSurname()
      alert(name);
      alert(surname );
    }

    firstFileFunction();

If you make an object using the constructor function and trying access the property or method from it in second file, it will give you the access of properties which are present in another file.

Just take care of sequence of including these files in index.html

SELECT * 
FROM tbl 
WHERE myDate BETWEEN #date one# AND #date two#;

This isn't possible - you need to carry out an UPDATE for each table individually.

WARNING: DUBIOUS, BUT IT'LL WORK (PROBABLY) SOLUTION FOLLOWS

Alternatively, you could dump the database via mysqldump and simply perform the search/replace on the resultant SQL file. (I'd recommend offlining anything that might touch the database whilst this is in progress, as well as using the --add-drop-table and --extended-insert flags.) However, you'd need to be sure that the search/replace text wasn't going to alter anything other than the data itself (i.e.: that the text you were going to swap out might not occur as a part of SQL syntax) and I'd really try doing the re-insert on an empty test database first.)

Slight change to @rejesh-yadav wonderful answer.

html2canvas now returns a promise.

html2canvas(document.body).then(function (canvas) {
    var img = canvas.toDataURL("image/png");
    var doc = new jsPDF();
    doc.addImage(img, 'JPEG', 10, 10);
    doc.save('test.pdf');        
});

Hope this helps some!

Simple way is

ArrayList<Dog> clonedList = new ArrayList<Dog>(dogs);

event.key === "Backspace"

More recent and much cleaner: use event.key. No more arbitrary number codes!

input.addEventListener('keydown', function(event) {
    const key = event.key; // const {key} = event; ES6+
    if (key === "Backspace" || key === "Delete") {
        return false;
    }
});

Someone pointed me to this thread because I had this same issue but it didn't work for me. After hours of searching I found a solution using this - https://github.com/rewish/jquery-bgswitcher#readme

It has a few other options other than fade too.

I recommend this article by my colleague Nick Parlante (from back when he was still at Stanford). The count of structurally different binary trees (problem 12) has a simple recursive solution (which in closed form ends up being the Catalan formula which @codeka's answer already mentioned).

I'm not sure how the number of structurally different binary search trees (BSTs for short) would differ from that of "plain" binary trees -- except that, if by "consider tree node values" you mean that each node may be e.g. any number compatible with the BST condition, then the number of different (but not all structurally different!-) BSTs is infinite. I doubt you mean that, so, please clarify what you do mean with an example!

I had the same error today but I tried something and surprisingly it worked. In the site packages folder there will be a file named wx.pth. Open it using notepad and its contents would be like "wx-2.8-msw-unicode"

It is basically the name of the folder containing wxpython. Delete this using Ctrl + A and copy the name of the folder from the site packages and paste it here even if it is the same.

Sounds weird but maybe the original file contained a hidden character...

'self' is only a reference to the object. 'del self' is deleting the 'self' reference from the local namespace of the kill function, instead of the actual object.

To see this for yourself, look at what happens when these two functions are executed:

>>> class A():
...     def kill_a(self):
...         print self
...         del self
...     def kill_b(self):
...         del self
...         print self
... 
>>> a = A()
>>> b = A()
>>> a.kill_a()
<__main__.A instance at 0xb771250c>
>>> b.kill_b()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 7, in kill_b

Convert it in dict.

write old function on your fields value for example

<input type="text" name="username" value="{{ old('username') }}">

Define the width as 960px, or whatever you prefer, and you're good to go!

#main {
 margin: 0 auto !important;
 float: none !important;
 text-align: center;
 width: 960px;
}

(I couldn't figure this out until I fixed the width, nothing else worked.)

Try this:

INSERT INTO `center_course_fee` (`fk_course_id`,`fk_center_code`,`course_fee`) VALUES ('69', '4920153', '6000') ON DUPLICATE KEY UPDATE `course_fee` = '6000';

You can allow the server to reuse an address with allow_reuse_address.

Whether the server will allow the reuse of an address. This defaults to False, and can be set in subclasses to change the policy.

import SimpleHTTPServer, SocketServer
PORT = 8000
httpd = SocketServer.TCPServer(("", PORT), SimpleHTTPServer.SimpleHTTPRequestHandler)
httpd.allow_reuse_address = True
print "Serving at port", PORT
httpd.serve_forever()

I investigate i knew that the jquery script need to load in order that why it not worked in your case. Because $ symbol mentioned in code not understand unless you load Jquery 1.9.1 at first. Load like follows

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/css/toastr.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/js/toastr.js"></script>

Then it will work fine

I got an error that the CURL extension was missing whilst installing WebMail Lite 8 on WAMP (so on Windows).

After reading that libeay32.dll was required which was only present in some of the PHP installation folders (such as 7.1.26), I switched the PHP version in use from 7.2.14 to 7.1.26 in the WAMP PHP version menu, and the error went away.

I have found that the 65536 limit still applies to pivot tables, even in Excel 2007.

Simply create a UICollectionViewFlowLayout subclass and paste this method.

override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
        guard let answer = super.layoutAttributesForElements(in: rect) else { return nil }

        for i in 1..<answer.count {
            let currentAttributes = answer[i]
            let previousAttributes = answer[i - 1]

            let maximumSpacing: CGFloat = 8
            let origin = previousAttributes.frame.maxX

            if (origin + maximumSpacing + currentAttributes.frame.size.width < self.collectionViewContentSize.width && currentAttributes.frame.origin.x > previousAttributes.frame.origin.x) {
                var frame = currentAttributes.frame
                frame.origin.x = origin + maximumSpacing
                currentAttributes.frame = frame
            }
        }

        return answer
}

I had this issue in VS 2015. The following solved it for me:

Find "webpages:Version" in the appsettings and update it to version 3.0.0.0. My web.config had

<add key="webpages:Version" value="2.0.0.0" />

and I updated it to

<add key="webpages:Version" value="3.0.0.0" />

I have searched a lot for a solution in which I can compare two array of objects with different attribute names (something like a left outer join). I came up with this solution. Here I used Lodash. I hope this will help you.

var Obj1 = [
    {id:1, name:'Sandra'},
    {id:2, name:'John'},   
];

var Obj2 = [
    {_id:2, name:'John'},
    {_id:4, name:'Bobby'}
];

var Obj3 = lodash.differenceWith(Obj1, Obj2, function (o1, o2) {
    return o1['id'] === o2['_id']
});

console.log(Obj3);
//  {id:1, name:'Sandra'}

See the MSDN getch docs. Specifically:

The _getch and_getwch functions read a single character from the console without echoing the character. None of these functions can be used to read CTRL+C. When reading a function key or an arrow key, each function must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.

The Python function returns a character. you can use ord() to get an integer value you can test, for example keycode = ord(msvcrt.getch()).

So if you read an 0x00 or 0xE0, read it a second time to get the key code for an arrow or function key. From experimentation, 0x00 precedes F1-F10 (0x3B-0x44) and 0xE0 precedes arrow keys and Ins/Del/Home/End/PageUp/PageDown.

The only thing you can do is to upload the image to a server and check the image size and dimension using some server side language like C#.

Edit:

Your need can't be done using javascript only.

This could be a simple way

border-right : 1px solid #ddd;
height:85px;    
box-shadow : 10px 0px 5px 1px #eaeaea;

Assign this to any div

Adding to Micah Carrick answer for django 1.8:

if settings.DEBUG:
  urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))

Is there any way to dump the call stack in a running process in C or C++ every time a certain function is called?

You can use a macro function instead of return statement in the specific function.

For example, instead of using return,

int foo(...)
{
    if (error happened)
        return -1;

    ... do something ...

    return 0
}

You can use a macro function.

#include "c-callstack.h"

int foo(...)
{
    if (error happened)
        NL_RETURN(-1);

    ... do something ...

    NL_RETURN(0);
}

Whenever an error happens in a function, you will see Java-style call stack as shown below.

Error(code:-1) at : so_topless_ranking_server (sample.c:23)
Error(code:-1) at : nanolat_database (sample.c:31)
Error(code:-1) at : nanolat_message_queue (sample.c:39)
Error(code:-1) at : main (sample.c:47)

Full source code is available here.

Basically it involved 3 steps

fileprivate func setupName() { 

    lblName.text = "Hello world"

    // Step 1
    lblName.translatesAutoresizingMaskIntoConstraints = false

    //Step 2
    self.view.addSubview(lblName)

    //Step 3
    NSLayoutConstraint.activate([
        lblName.centerXAnchor.constraint(equalTo: self.view.centerXAnchor),
        lblName.centerYAnchor.constraint(equalTo: self.view.centerYAnchor)
    ])
}

This puts label "hello world" in center of screen.

Please refer link Autolayout constraints programmatically

check this fiddle , and if you want to move the overlapped div you set its position to absolute then change it's top and left values

Check out this GitHub repository that describes best practices for AngularJS apps. It has naming conventions for different components. It is not complete, but it is community-driven so everyone can contribute.

set the height to 200

Set the Font to a large variant (150+ px). As already mentioned, control the width using columns, and use a layout manager (or constraint) that will respect the preferred width & height.

As other have said, compiled and interpreted are specific to an implementation of a programming language; they are not inherent in the language. For example, there are C interpreters.

However, we can (and in practice we do) classify programming languages based on its most common (sometimes canonical) implementation. For example, we say C is compiled.

First, we must define without ambiguity interpreters and compilers:

An interpreter for language X is a program (or a machine, or just some kind of mechanism in general) that executes any program p written in language X such that it performs the effects and evaluates the results as prescribed by the specification of X.

A compiler from X to Y is a program (or a machine, or just some kind of mechanism in general) that translates any program p from some language X into a semantically equivalent program p' in some language Y in such a way that interpreting p' with an interpreter for Y will yield the same results and have the same effects as interpreting p with an interpreter for X.

Notice that from a programmer point of view, CPUs are machine interpreters for their respective native machine language.

Now, we can do a tentative classification of programming languages into 3 categories depending on its most common implementation:

• Hard Compiled languages: When the programs are compiled entirely to machine language. The only interpreter used is a CPU. Example: Usually, to run a program in C, the source code is compiled to machine language, which is then executed by a CPU.
• Interpreted languages: When there is no compilation of any part of the original program to machine language. In other words, no new machine code is generated; only existing machine code is executed. An interpreter other than the CPU must also be used (usually a program).Example: In the canonical implementation of Python, the source code is compiled first to Python bytecode and then that bytecode is executed by CPython, an interpreter program for Python bytecode.
• Soft Compiled languages: When an interpreter other than the CPU is used but also parts of the original program may be compiled to machine language. This is the case of Java, where the source code is compiled to bytecode first and then, the bytecode may be interpreted by the Java Interpreter and/or further compiled by the JIT compiler.

Sometimes, soft and hard compiled languages are refered to simply compiled, thus C#, Java, C, C++ are said to be compiled.

Within this categorization, JavaScript used to be an interpreted language, but that was many years ago. Nowadays, it is JIT-compiled to native machine language in most major JavaScript implementations so I would say that it falls into soft compiled languages.

As a workaround, you may use...

Windows Powershell ISE

As the Powershell script editor does not seems to have a buffer limitation in its read-eval-print-loop part (the "blue" part). And with Powershell you may execute DOS commands as well.

PS. I understand this answer is a bit aside the original question, however I believe it is good to mention as it is a good workaround.

I realize this question has already been answered, however, I had a different solution:

If you are writing a script where you drop the tables without recreating them, those tables will show as missing if you try to reference them later on.

Note: This isn't going to happen with a script that is constantly ran, but sometimes it's easier to have a script with queries to reerence than to type them everytime.

Although not necessarily a JavaScript solution, there is also a "title" global tag attribute that may be helpful.

<a href="https://stackoverflow.com/questions/3559467/description-box-on-mouseover" title="This is a title.">Mouseover me</a>

Mouseover me

This function shortens a string by adding "..." at a word boundary whenever possible. The returned string will have a maximum length of $len including "...".

function truncate($str, $len) {
  $tail = max(0, $len-10);
  $trunk = substr($str, 0, $tail);
  $trunk .= strrev(preg_replace('~^..+?[\s,:]\b|^...~', '...', strrev(substr($str, $tail, $len-$tail))));
  return $trunk;
}

Examples outputs:

• truncate("Thanks for contributing an answer to Stack Overflow!", 15)
  returns "Thanks for..."
• truncate("To learn more, see our tips on writing great answers.", 15)
  returns "To learn more..." (comma also truncated)
• truncate("Pseudopseudohypoparathyroidism", 15)
  returns "Pseudopseudo..."

From my understanding matplotlib is a plotting library.

If you want to change the image data (e.g. draw a rectangle on an image), you could use PIL's ImageDraw, OpenCV, or something similar.

Here is PIL's ImageDraw method to draw a rectangle.

Here is one of OpenCV's methods for drawing a rectangle.

Your question asked about Matplotlib, but probably should have just asked about drawing a rectangle on an image.

Here is another question which addresses what I think you wanted to know: Draw a rectangle and a text in it using PIL

You have to specify negative spread in the box shadow to remove side shadow

-webkit-box-shadow: 0 10px 10px -10px #000000;
   -moz-box-shadow: 0 10px 10px -10px #000000;
        box-shadow: 0 10px 10px -10px #000000;

The Bootstrap datepicker is able to set date-range. But it is not available in the initial release/Master Branch. Check the branch as 'range' there (or just see at https://github.com/eternicode/bootstrap-datepicker), you can do it simply with startDate and endDate.

Example:

$('#datepicker').datepicker({
    startDate: '-2m',
    endDate: '+2d'
});

If you are unaware of the position to replace, use list iterator to find and replace element ListIterator.set(E e)

ListIterator<String> iterator = list.listIterator();
while (iterator.hasNext()) {
     String next = iterator.next();
     if (next.equals("Two")) {
         //Replace element
         iterator.set("New");
     }
 }

The TextBox control has a Text property that you can use to get (or set) the text of the textbox.

The most portable regex would be ^[ \t\n]*$ to match an empty string (note that you would need to replace \t and \n with tab and newline accordingly) and [^ \n\t] to match a non-whitespace string.

Linux users can find the locations of all the installed packages like this:

pip list | xargs -exec pip show

You can use flex-grow: 1. The default value is 0 and it will cause the text-align: center looks like left.

I just want to add something to these great answers. If your DOM element ins't loading in time. You can still set the value.

let Ctrl = $('#mySelectElement'); ... Ctrl.attr('value', myValue);

after that most DOM elements that accept a value attribute should populate correctly.

InetAddress.getByName also works for ip address.

From the JavaDoc

The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.

Alternatively, when you want to save individual R objects, I recommend using saveRDS.

You can save R objects using saveRDS, then load them into R with a new variable name using readRDS.

Example:

# Save the city object
saveRDS(city, "city.rds")

# ...

# Load the city object as city
city <- readRDS("city.rds")

# Or with a different name
city2 <- readRDS("city.rds")

But when you want to save many/all your objects in your workspace, use Manetheran's answer.

In addition to the locations listed above, the OS X version of Perl also has two more ways:

6. The /Library/Perl/x.xx/AppendToPath file. Paths listed in this file are appended to @INC at runtime.

7. The /Library/Perl/x.xx/PrependToPath file. Paths listed in this file are prepended to @INC at runtime.

During the installation you got a message Composer successfully installed to: ... this indicates where Composer was installed. But you might also search for the file composer.phar on your system.

Then simply:

1. Delete the file composer.phar.
2. Delete the Cache Folder:
   • Linux: /home/<user>/.composer
   • Windows: C:\Users\<username>\AppData\Roaming\Composer

That's it.

CSS

I used to use the following from CSS-Tricks:

.transparent_class {
  /* IE 8 */
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";

  /* IE 5-7 */
  filter: alpha(opacity=50);

  /* Netscape */
  -moz-opacity: 0.5;

  /* Safari 1.x */
  -khtml-opacity: 0.5;

  /* Good browsers */
  opacity: 0.5;
}

Compass

However, a better solution is to use the Opacity Compass mixin, all you need to do is to @include opacity(0.1); and it will take care of any cross-browser issues for you. You can find an example here.

Here's a great reason to use objectForKey: wherever possible instead of valueForKey: - valueForKey: with an unknown key will throw NSUnknownKeyException saying "this class is not key value coding-compliant for the key ".

In addition to the repository permissions, the /tmp directory must also be writeable by all users.

The loop attribute should do it:

<video width="320" height="240" autoplay loop>
  <source src="movie.mp4" type="video/mp4" />
  <source src="movie.ogg" type="video/ogg" />
  Your browser does not support the video tag.
</video>

Should you have a problem with the loop attribute (as we had in the past), listen to the videoEnd event and call the play() method when it fires.

Note1: I'm not sure about the behavior on Apple's iPad/iPhone, because they have some restrictions against autoplay.

Note2: loop="true" and autoplay="autoplay" are deprecated

If you have input field like

<input type="file" id="file" name="file" onchange="add(event)"/>

You can get to file content in BLOB format:

function add(event){
  var userFile = document.getElementById('file');
  userFile.src = URL.createObjectURL(event.target.files[0]);
  var data = userFile.src;
}

You need also $sce.trustAsResourceUrl or it won't open the website inside the iframe:

angular.module('myApp', [])_x000D_
    .controller('dummy', ['$scope', '$sce', function ($scope, $sce) {_x000D_
_x000D_
    $scope.url = $sce.trustAsResourceUrl('https://www.angularjs.org');_x000D_
_x000D_
    $scope.changeIt = function () {_x000D_
        $scope.url = $sce.trustAsResourceUrl('https://docs.angularjs.org/tutorial');_x000D_
    }_x000D_
}]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<div ng-app="myApp" ng-controller="dummy">_x000D_
    <iframe ng-src="{{url}}" width="300" height="200"></iframe>_x000D_
    <br>_x000D_
    <button ng-click="changeIt()">Change it</button>_x000D_
</div>

There is often the tip to use 'echo.'

But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.

You could use echo(. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.

More about the different ECHO:/\ variants is at DOS tips: ECHO. FAILS to give text or blank line.

If you happen to have AWS S3 that works like a charm also. Well. Relatively speaking :-)

Create a bucket for your ad hocs in AWS, add an index file (it can just be a blank index.html file) then using a client that can connect to S3 like CyberDuck or Coda (I used Coda - where you'd select Add Site to get a connection window) then set the connections like the attached:

Then build your enterprise ad hoc in XCode and make sure you use https://s3.amazonaws.com/your-bucket-name/your-ad-hoc-folder/your-app.ipa as the Application URL, and upload it to your new S3 bucket directory.

Your itms link should match, i.e. itms-services://?action=download-manifest&url=https://s3.amazonaws.com/your-bucket-name/your-ad-hoc-folder/your-app.plist

And voilá.

This is only for generic AWS URLs - I haven't tried with custom URLs on AWS so you might have to do a few things differently.

I was determined to try to make James Webster's solution above work, but I couldn't get it to work with Plesk.

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

You can use the git show command.

To get the last commit date from git repository in a long(Unix epoch timestamp):

• Command: git show -s --format=%ct
• Result: 1605103148

Note: You can visit the git-show documentation to get a more detailed description of the options.

It's not a matter of deep copy or shallow copy, none of what you're doing is deep copy.

Here:

>>> new = original 

you're creating a new reference to the the list/dict referenced by original.

while here:

>>> new = original.copy()
>>> # or
>>> new = list(original) # dict(original)

you're creating a new list/dict which is filled with a copy of the references of objects contained in the original container.

Remove ng.ps1 from the directory C:\Users\%username%\AppData\Roaming\npm\ then try clearing the npm cache at C:\Users\%username%\AppData\Roaming\npm-cache\

With jQuery, you can try to call trigger:

$(window).trigger('resize');

I'd recommend using the subprocess module instead of os.system because it does shell escaping for you and is therefore much safer.

subprocess.call(['ping', 'localhost'])

function alphaOnly(event) {
  var key = event.keyCode;
  return ((key >= 65 && key <= 90) || key == 8);
};

or

function lettersOnly(evt) {
       evt = (evt) ? evt : event;
       var charCode = (evt.charCode) ? evt.charCode : ((evt.keyCode) ? evt.keyCode :
          ((evt.which) ? evt.which : 0));
       if (charCode > 31 && (charCode < 65 || charCode > 90) &&
          (charCode < 97 || charCode > 122)) {
          alert("Enter letters only.");
          return false;
       }
       return true;
     }

You need to call the hasOwnProperty function to check whether the property is actually defined on the object itself (as opposed to its prototype), like this:

for (var key in widthRange) {
    if (key === 'length' || !widthRange.hasOwnProperty(key)) continue;
    var value = widthRange[key];
}

Note that you need a separate check for length.
However, you shouldn't be using an array here at all; you should use a regular object. All Javascript objects function as associative arrays.

For example:

var widthRange = { };  //Or new Object()
widthRange[46] = { sel:46, min:0,  max:52 };
widthRange[66] = { sel:66, min:52, max:70 };
widthRange[90] = { sel:90, min:70, max:94 };

find your target element "d" however you wish and then:

d.className += ' additionalClass'; //note the space

you can wrap that in cleverer ways to check pre-existence, and check for space requirements etc..

Other Note

In response to Aquarius Power in the comment above, We need to store the regex on a var

The variable BASH_REMATCH is set after you match the expression, and ${BASH_REMATCH[n]} will match the nth group wrapped in parentheses ie in the following ${BASH_REMATCH[1]} = "compressed" and ${BASH_REMATCH[2]} = ".gz"

if [[ "compressed.gz" =~ ^(.*)(\.[a-z]{1,5})$ ]]; 
then 
  echo ${BASH_REMATCH[2]} ; 
else 
  echo "Not proper format"; 
fi

(The regex above isn't meant to be a valid one for file naming and extensions, but it works for the example)

http://rolandtapken.de/blog/2012-04/java-process-httpproxyuser-and-httpproxypassword says:

Other suggest to use a custom default Authenticator. But that's dangerous because this would send your password to anybody who asks.

This is relevant if some http/https requests don't go through the proxy (which is quite possible depending on configuration). In that case, you would send your credentials directly to some http server, not to your proxy.

He suggests the following fix.

// Java ignores http.proxyUser. Here come's the workaround.
Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        if (getRequestorType() == RequestorType.PROXY) {
            String prot = getRequestingProtocol().toLowerCase();
            String host = System.getProperty(prot + ".proxyHost", "");
            String port = System.getProperty(prot + ".proxyPort", "80");
            String user = System.getProperty(prot + ".proxyUser", "");
            String password = System.getProperty(prot + ".proxyPassword", "");

            if (getRequestingHost().equalsIgnoreCase(host)) {
                if (Integer.parseInt(port) == getRequestingPort()) {
                    // Seems to be OK.
                    return new PasswordAuthentication(user, password.toCharArray());  
                }
            }
        }
        return null;
    }  
});

I haven't tried it yet, but it looks good to me.

I modified the original version slightly to use equalsIgnoreCase() instead of equals(host.toLowerCase()) because of this: http://mattryall.net/blog/2009/02/the-infamous-turkish-locale-bug and I added "80" as the default value for port to avoid NumberFormatException in Integer.parseInt(port).

It doesn't work because name is a reserved word in JavaScript. Change the function name to something else.

See http://www.quackit.com/javascript/javascript_reserved_words.cfm

<form id="form" onsubmit="return false;">
    <input style="position:absolute; top:80%; left:5%; width:40%;" type="text" id="userInput" />
    <input style="position:absolute; top:50%; left:5%; width:40%;" type="submit" onclick="othername();" />
</form>

function othername() {
    var input = document.getElementById("userInput").value;
    alert(input);
}

If you want to keep the upstream repository with full history, but local smaller checkouts, do a shallow clone with git clone --depth=1 [repo].

After pushing a commit, you can do

1. git fetch --depth=1 to prune the old commits. This makes the old commits and their objects unreachable.
2. git reflog expire --expire-unreachable=now --all. To expire all old commits and their objects
3. git gc --aggressive --prune=all to remove the old objects

See also How to remove local git history after a commit?.

Note that you cannot push this "shallow" repository to somewhere else: "shallow update not allowed". See Remote rejected (shallow update not allowed) after changing Git remote URL. If you want to to that, you have to stick with grafting.

Some things seem appeared to have changed in batch scripts on Windows 8, and the solution above by DGG now causes the Command Prompt to crash.

The following solution worked for me:

@echo off
set /a n=0
:repeat
set /a n+=1
echo 192.168.1.%n%
ping -n 1 -w 500 192.168.1.%n% | FIND /i "Reply">>ipaddresses.txt

If by join you mean union, try this:

set(list(s) + list(t))

It's a bit of a hack, but I can't think of a better one liner to do it.

I've noticed SequenceDiagram plugin for Intellij is also a good option.

The kernel might be the operating system or it might be a part of the operating system. In Linux, the kernel is loaded and executed first. Then it starts up other bits of the OS (like init) to make the system useful.

This is especially true in a micro-kernel environment. The kernel has minimal functionality. Everything else, like file systems and TCP/IP, run as a user process.

At first it seems as if JNZ means jump if not Zero (0), as in jump if zero flag is 1/set.

But in reality it means Jump (if) not Zero (is set).

If 0 = not set and 1 = set then just remember:
JNZ Jumps if the zero flag is not set (0)

I think you want something along the lines of this:

echo Your Msg> YourTxtFile.txt

Or if you want a new line:

echo Your Msg>> YourTxtFile.txt

These commands are great for logs.

Note: This will sometimes glitch and replace the whole text file on my computer.

Another Note: If the file does not exist, it will create the file.

Due to the mixed comments about BuildConfig.DEBUG, I used the following to disable crashlytics (and analytics) in debug mode :

update /app/build.gradle

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.1"

    defaultConfig {
        applicationId "your.awesome.app"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 100
        versionName "1.0.0"
        buildConfigField 'boolean', 'ENABLE_CRASHLYTICS', 'true'
    }
    buildTypes {
        debug {
            debuggable true
            minifyEnabled false
            buildConfigField 'boolean', 'ENABLE_CRASHLYTICS', 'false'
        }
        release {
            debuggable false
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

then, in your code you detect the ENABLE_CRASHLYTICS flag as follows:

    if (BuildConfig.ENABLE_CRASHLYTICS)
    {
        // enable crashlytics and answers (Crashlytics by default includes Answers)
        Fabric.with(this, new Crashlytics());
    }

use the same concept in your app and rename ENABLE_CRASHLYTICS to anything you want. I like this approach because I can see the flag in the configuration and I can control the flag.

An other very good documentation tool is sphinx. It will be used for the upcoming python 2.6 documentation and is used by django and a lot of other python projects.

From the sphinx website:

• Output formats: HTML (including Windows HTML Help) and LaTeX, for printable PDF versions
• Extensive cross-references: semantic markup and automatic links for functions, classes, glossary terms and similar pieces of information
• Hierarchical structure: easy definition of a document tree, with automatic links to siblings, parents and children
• Automatic indices: general index as well as a module index
• Code handling: automatic highlighting using the Pygments highlighter
• Extensions: automatic testing of code snippets, inclusion of docstrings from Python modules, and more

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

If your URL is:

http://127.0.0.1:8080/binding/

Update the below property in the index.html

<base href="/binding/">

In short, you need to check the locations of the files.

EOF is -1 because that's how it's defined. The name is provided by the standard library headers that you #include. They make it equal to -1 because it has to be something that can't be mistaken for an actual byte read by getchar(). getchar() reports the values of actual bytes using positive number (0 up to 255 inclusive), so -1 works fine for this.

The != operator means "not equal". 0 stands for false, and anything else stands for true. So what happens is, we call the getchar() function, and compare the result to -1 (EOF). If the result was not equal to EOF, then the result is true, because things that are not equal are not equal. If the result was equal to EOF, then the result is false, because things that are equal are not (not equal).

The call to getchar() returns EOF when you reach the "end of file". As far as C is concerned, the 'standard input' (the data you are giving to your program by typing in the command window) is just like a file. Of course, you can always type more, so you need an explicit way to say "I'm done". On Windows systems, this is control-Z. On Unix systems, this is control-D.

The example in the book is not "wrong". It depends on what you actually want to do. Reading until EOF means that you read everything, until the user says "I'm done", and then you can't read any more. Reading until '\n' means that you read a line of input. Reading until '\0' is a bad idea if you expect the user to type the input, because it is either hard or impossible to produce this byte with a keyboard at the command prompt :)

According to Pure CSS Scrollable Table with Fixed Header , I wrote a DEMO to easily fix the header by setting overflow:auto to the tbody.

table thead tr{
    display:block;
}

table th,table td{
    width:100px;//fixed width
}


table  tbody{
  display:block;
  height:200px;
  overflow:auto;//set tbody to auto
}

1. //pull the latest changes of current development branch if any        
git pull (current development branch)

2. //switch to master branch
git checkout master 

3. //pull all the changes if any
git pull

4. //Now merge development into master    
git merge development

5. //push the master branch
git push origin master

I think you want preg_split:

$input = "A  B C   D";
$words = preg_split('/\s+/', $input);
var_dump($words);

You can use

substr(string $string, int $start, int[optional] $length=null);

See substr in the PHP documentation. It returns part of a string.

@VonC's answer to a duplicate question:

If, as commented, Paraminko does not support PPK key, the official solution, as seen here, would be to use PuTTYgen.

But you can also use the Python library CkSshKey to make that same conversion directly in your program.

See "Convert PuTTY Private Key (ppk) to OpenSSH (pem)"

import sys
import chilkat

key = chilkat.CkSshKey()

#  Load an unencrypted or encrypted PuTTY private key.

#  If  your PuTTY private key is encrypted, set the Password
#  property before calling FromPuttyPrivateKey.
#  If your PuTTY private key is not encrypted, it makes no diffference
#  if Password is set or not set.
key.put_Password("secret")

#  First load the .ppk file into a string:

keyStr = key.loadText("putty_private_key.ppk")

#  Import into the SSH key object:
success = key.FromPuttyPrivateKey(keyStr)
if (success != True):
    print(key.lastErrorText())
    sys.exit()

#  Convert to an encrypted or unencrypted OpenSSH key.

#  First demonstrate converting to an unencrypted OpenSSH key

bEncrypt = False
unencryptedKeyStr = key.toOpenSshPrivateKey(bEncrypt)
success = key.SaveText(unencryptedKeyStr,"unencrypted_openssh.pem")
if (success != True):
    print(key.lastErrorText())
    sys.exit()

I think people in this post are missing the most important point for anyone who has never used a functional programming language: expanding your mind. If you are new to functional programming then Haskell will make you think in ways you've never thought before. As a result your programming in other areas and other languages will improve. How much? Hard to quantify.

I suppose you could use a solution such as this one :

select name, length(name)
from users
where id = (
    select id
    from users
    order by length(name) desc
    limit 1
);

Might not be the optimal solution, though... But seems to work.

The accepted answer will work if you can easily reproduce the issue. However, as a matter of best practice, you should be catching any exceptions (and logging) that are executed within a task. Otherwise, your application will crash if anything unexpected occurs within the task.

Task.Factory.StartNew(x=>
   throw new Exception("I didn't account for this");
)

However, if we do this, at least the application does not crash.

Task.Factory.StartNew(x=>
   try {
      throw new Exception("I didn't account for this");
   }
   catch(Exception ex) {
      //Log ex
   }
)

I guess this is what you are looking for?

Added an example:

The html:

<div class="example-date">
  <span class="day">31</span> 
  <span class="month">July</span> 
  <span class="year">2009</span>
</div>

The css:

.year
{
    display:block;
    -webkit-transform: rotate(-90deg); 
    -moz-transform: rotate(-90deg); 
    filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3); //For IE support
}

Alle examples are from the mentioned site.

This site explain step by step that what you need to do Certificates, Identifiers & Profiles and as your question

"Valid Signing identity not found"?

You need the private key that were used to sign the code base with provisioning profile. . If you don't have then you can generate a new signing request on the iOS developer portal.

For Export:

Xcode -> Organizer, select your team. Click Export. Specify a filename and a password, and click Save.`

For Import:

Xcode -> Organizer, select your team. Click Import. Select the file containing your code signing assets. Enter the password for the file, and click Open.

The transmission delay is the amount of time required for the router to push out the packet.

The propagation delay, is the time it takes a bit to propagate from one router to the next.

the transmission and propagation delay are completely different! if denote the length of the packet by L bits, and denote the transmission rate of the link from first router to second router by R bits/sec. then transmission delay will be L/R. and this is depended to transmission rate of link and the length of packet.

then if denote the distance between two routers d and denote the propagation speed s, the propagation delay will be d/s. it is a function of the Distance between the two routers, but has no dependence to the packet's length or the transmission rate of the link.

further to what @JohnTESlade has answered. Google's python style guide has some pretty neat recommendations,

Names to Avoid

• single character names except for counters or iterators
• dashes (-) in any package/module name
• \__double_leading_and_trailing_underscore__ names (reserved by Python)

Naming Convention

• "Internal" means internal to a module or protected or private within a class.
• Prepending a single underscore (_) has some support for protecting module variables and functions (not included with import * from). Prepending a double underscore (__) to an instance variable or method effectively serves to make the variable or method private to its class (using name mangling).
• Place related classes and top-level functions together in a module. Unlike Java, there is no need to limit yourself to one class per module.
• Use CapWords for class names, but lower_with_under.py for module names. Although there are many existing modules named CapWords.py, this is now discouraged because it's confusing when the module happens to be named after a class. ("wait -- did I write import StringIO or from StringIO import StringIO?")

Guidelines derived from Guido's Recommendations

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

A single star means that the variable 'a' will be a tuple of extra parameters that were supplied to the function. The double star means the variable 'kw' will be a variable-size dictionary of extra parameters that were supplied with keywords.

Although the actual behavior is spec'd out, it still sometimes can be very non-intuitive. Writing some sample functions and calling them with various parameter styles may help you understand what is allowed and what the results are.

def f0(a)
def f1(*a)
def f2(**a)
def f3(*a, **b)
etc...

Why not check HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\[office.exe], where [office.exe] stands for particular office product exe-filename, e.g. winword.exe, excel.exe etc. There you get path to executable and check version of that file.

How to check version of the file: in C++ / in C#

Any criticism towards such approach?

Here is another simple implementation -

/**
 * Date range
 *
 * @param $first
 * @param $last
 * @param string $step
 * @param string $format
 * @return array
 */
function dateRange( $first, $last, $step = '+1 day', $format = 'Y-m-d' ) {
    $dates = [];
    $current = strtotime( $first );
    $last = strtotime( $last );

    while( $current <= $last ) {

        $dates[] = date( $format, $current );
        $current = strtotime( $step, $current );
    }

    return $dates;
}

Example:

print_r( dateRange( '2010-07-26', '2010-08-05') );

Array (
    [0] => 2010-07-26
    [1] => 2010-07-27
    [2] => 2010-07-28
    [3] => 2010-07-29
    [4] => 2010-07-30
    [5] => 2010-07-31
    [6] => 2010-08-01
    [7] => 2010-08-02
    [8] => 2010-08-03
    [9] => 2010-08-04
    [10] => 2010-08-05
)

This may not be the answer you're looking for, but I'd recommend using the now community maintained repository Laravel Collective Forms & HTML as the main repositories have been deprecated.

Laravel Collective is in the process of updating their website. You may view the documentation on GitHub if needed.

Here is an example for passing parameters to a fxml document through namespace.

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.layout.VBox?>
<VBox xmlns="http://javafx.com/javafx/null" xmlns:fx="http://javafx.com/fxml/1">
    <BorderPane>
        <center>
            <Label text="$labelText"/>
        </center>
    </BorderPane>
</VBox>

Define value External Text for namespace variable labelText:

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

import java.io.IOException;

public class NamespaceParameterExampleApplication extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws IOException {
        final FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("namespace-parameter-example.fxml"));

        fxmlLoader.getNamespace()
                  .put("labelText", "External Text");

        final Parent root = fxmlLoader.load();

        primaryStage.setTitle("Namespace Parameter Example");
        primaryStage.setScene(new Scene(root, 400, 400));
        primaryStage.show();
    }
}

To read user input you can try the cmd module for easily creating a mini-command line interpreter (with help texts and autocompletion) and raw_input (input for Python 3+) for reading a line of text from the user.

text = raw_input("prompt")  # Python 2
text = input("prompt")  # Python 3

Command line inputs are in sys.argv. Try this in your script:

import sys
print (sys.argv)

There are two modules for parsing command line options: optparse (deprecated since Python 2.7, use argparse instead) and getopt. If you just want to input files to your script, behold the power of fileinput.

The Python library reference is your friend.

If you just want to add the same header to all the requests to the service, you can do it with out any coding!
Just add the headers node with required headers under the endpoint node in your client config file

<client>  
  <endpoint address="http://localhost/..." >  
    <headers>  
      <HeaderName>Value</HeaderName>  
    </headers>   
 </endpoint>  

I think you would be look at String class, there are multiple ways to do it. What about substring(int,int) and indexOf(int) lastIndexOf(int)?

C#, because I don't want to typo the VB syntax.

Markup:

<div runat="server" id="divControl">...</div>

Class of the Page:

protected System.Web.UI.HtmlControls.HtmlGenericControl divControl;

OnLoad/Other function:

divControl.Style.Add("height", number / anotherNumer);

Go to project directory .vs/config/ and remove applicationhost.config . Then restart project.

I had a similar issue with the following JavaScript code:

var url = 'http://my-host-name.com/api/Rating';

var rating = { 
  value: 5,
  maxValue: 10
};

$.post(url, JSON.stringify(rating), showSavedNotification);

Where in the Fiddler I could see the request with:

• Header: Content-Type: application/x-www-form-urlencoded; charset=UTF-8
• Body: {"value":"5","maxValue":"5"}

As a result, my server couldn't map an object to a server-side type.

After changing the last line to this one:

$.post(url, rating, showSavedNotification);

In the Fiddler I could still see:

• Header: Content-Type: application/x-www-form-urlencoded; charset=UTF-8
• Body: value=5&maxValue=10

However, the server started returning what I expected.

Pojo also consider as Model class in Java where we can create getter and setter for particular variable defined in private . Remember all variables are here declared with private modifier

BufferedWriter is more efficient. It saves up small writes and writes in one larger chunk if memory serves me correctly. If you are doing lots of small writes then I would use BufferedWriter. Calling write calls to the OS which is slow so having as few writes as possible is usually desirable.

Alternative: you can use the less command.

Type in console:

"your_command" | less   

This will allow you to scroll with the up and down arrow keys.

Basically your output has been piped with the less command.

I've found you can use a very non verbose and straightforward approach to checking for the existence various SQL Server objects this way:

IF OBJECTPROPERTY (object_id('schemaname.scalarfuncname'), 'IsScalarFunction') = 1
IF OBJECTPROPERTY (object_id('schemaname.tablefuncname'), 'IsTableFunction') = 1
IF OBJECTPROPERTY (object_id('schemaname.procname'), 'IsProcedure') = 1

This is based on the OBJECTPROPERTY function which is available in SQL 2005+. The MSDN article can be found here.

The OBJECTPROPERTY function uses the following signature:

OBJECTPROPERTY ( id , property ) 

You pass a literal value into the property parameter, designating the type of object you are looking for. There's a massive list of values you can supply.

I got the Error even though i was catching the exception.

    try {
        bitmap = BitmapFactory.decodeStream(getAssets().open("kitten.jpg"));
    } catch (IOException e) {
        Log.e("blabla", "Error", e);
        finish();
    }

Issue was that the IOException wasn't imported

import java.io.IOException;

I was able to do this using CefSharp (which uses chromium browser).

Check if ceil function and floor function returns the same value

static boolean isInteger(int n) 
{ 
return (int)(Math.ceil(n)) == (int)(Math.floor(n)); 
} 

select get_something('NAME', sys.diutil.int_to_bool(1)) from dual;

{ find . -maxdepth 1 -type f | xargs ls -1t | less; }

added xargs to make it works, and used -1 instead of -l to show only filenames without additional ls info

I don't see df.write.saveAsTable(...) deprecated in Spark 2.0 documentation. It has worked for us on Amazon EMR. We were perfectly able to read data from S3 into a dataframe, process it, create a table from the result and read it with MicroStrategy. Vinays answer has also worked though.

As mentioned above,

show procedure status;

Will indeed show a list of procedures, but shows all of them, server-wide.

If you want to see just the ones in a single database, try this:

SHOW PROCEDURE STATUS WHERE Db = 'databasename';

Both are correct. Oracle allows the use of both.

Add $.fancybox.close() to where ever you want it to be trigged, in a function or a callback, end of an ajax call!

Woohoo.

Look at my simple utility to show some info about db schema. It is based on: Reverse Engineering a Data Model Using the Oracle Data Dictionary

To me its all about knowing your data. If I am continuing to expand my code on the basis of efficiency, I would have to choose the List option as a way of deciphering of my data w/o the unnecessary step of always wondering about types, especially 'Custom Types'. If the machine understands the difference and can determine on it's on what type of data I'm actually dealing with then why should I get in the way and waste time going thru the gyrations of 'IF THEN ELSE' determinations? My philosophy is to let the machine work for me instead of me working on the machine? Knowing the unique differences of different object code commands goes a long way in making your code as efficient.

Tom Johnson (One Entry ... One Exit)

foo = {}
foo[#foo+1]="bar"
foo[#foo+1]="baz"

This works because the # operator computes the length of the list. The empty list has length 0, etc.

If you're using Lua 5.3+, then you can do almost exactly what you wanted:

foo = {}
setmetatable(foo, { __shl = function (t,v) t[#t+1]=v end })
_= foo << "bar"
_= foo << "baz"

Expressions are not statements in Lua and they need to be used somehow.

Kill The Group Using Only Name of Process Which Belongs to Group:

kill -- -$(ps -ae o pid,pgrp,cmd | grep "[e]xample.py" | awk '{print $2}' | tail -1)

This is a modification of olibre's answer but you don't need to know the PID, just the name of a member of the group.

Explanation:

To get the group id you do the ps command using the arguments as shown, grep it for your command, but formatting example.py with quotes and using the bracket for the first letter (this filters out the grep command itself) then filter it through awk to get the second field which is the group id. The tail -1 gets rid of duplicate group ids. You put all of that in a variable using the $() syntax and voila – you get the group id. So you substitute that $(mess) for that -groupid above.

Please reference :Spring Data JPA @Query, if you are using Spring Data JPA version 2.0.4 and later. Sample like below:

@Query(value = "SELECT u FROM User u ORDER BY id")
Page<User> findAllUsersWithPagination(Pageable pageable);

You can use the --ignore-table option. So you could do

mysqldump -u USERNAME -pPASSWORD DATABASE --ignore-table=DATABASE.table1 > database.sql

There is no whitespace after -p (this is not a typo).

To ignore multiple tables, use this option multiple times, this is documented to work since at least version 5.0.

If you want an alternative way to ignore multiple tables you can use a script like this:

#!/bin/bash
PASSWORD=XXXXXX
HOST=XXXXXX
USER=XXXXXX
DATABASE=databasename
DB_FILE=dump.sql
EXCLUDED_TABLES=(
table1
table2
table3
table4
tableN   
)
 
IGNORED_TABLES_STRING=''
for TABLE in "${EXCLUDED_TABLES[@]}"
do :
   IGNORED_TABLES_STRING+=" --ignore-table=${DATABASE}.${TABLE}"
done

echo "Dump structure"
mysqldump --host=${HOST} --user=${USER} --password=${PASSWORD} --single-transaction --no-data --routines ${DATABASE} > ${DB_FILE}

echo "Dump content"
mysqldump --host=${HOST} --user=${USER} --password=${PASSWORD} ${DATABASE} --no-create-info --skip-triggers ${IGNORED_TABLES_STRING} >> ${DB_FILE}

On how to change values in appSettings section in your app.config file:

config.AppSettings.Settings.Remove(key);
config.AppSettings.Settings.Add(key, value);

does the job.

Of course better practice is Settings class but it depends on what are you after.

As Get-Date returns a DateTime object you are able to compare them directly. An example:

(get-date 2010-01-02) -lt (get-date 2010-01-01)

will return false.

The string is surrounded by double quotes. Yes, that's not a valid character in a path.

You should probably tackle it at the source, but you can strip them out with:

        path = path.Replace("\"", "");

The error was that you cannot use this in the grep, but you must use a reference to the element. This works:

function findPurpose(purposeName){
    return $.grep(purposeObjects, function(n, i){
      return n.purpose == purposeName;
    });
};

findPurpose("daily");

returns:

[Object { purpose="daily"}]

Origin null is the local file system, so that suggests that you're loading the HTML page that does the load call via a file:/// URL (e.g., just double-clicking it in a local file browser or similar). Different browsers take different approaches to applying the Same Origin Policy to local files.

My guess is that you're seeing this using Chrome. Chrome's rules for applying the SOP to local files are very tight, it disallows even loading files from the same directory as the document. So does Opera. Some other browsers, such as Firefox, allow limited access to local files. But basically, using ajax with local resources isn't going to work cross-browser.

If you're just testing something locally that you'll really be deploying to the web, rather than use local files, install a simple web server and test via http:// URLs instead. That gives you a much more accurate security picture.

I have faced with this trouble during a development of automation tests for our REST API. JDK 7_80 was installed at my machine only. Before I installed JDK 8, everything worked just fine and I had a possibility to obtain OAuth 2.0 tokens with a JMeter. After I installed JDK 8, the nightmare with Certificates does not conform to algorithm constraints began.

Both JMeter and Serenity did not have a possibility to obtain a token. JMeter uses the JDK library to make the request. The library just raises an exception when the library call is made to connect to endpoints that use it, ignoring the request.

The next thing was to comment all the lines dedicated to disabledAlgorithms in ALL java.security files.

C:\Java\jre7\lib\security\java.security
C:\Java\jre8\lib\security\java.security
C:\Java\jdk8\jre\lib\security\java.security
C:\Java\jdk7\jre\lib\security\java.security

Then it started to work at last. I know, that's a brute force approach, but it was the most simple way to fix it.

# jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 768
# jdk.certpath.disabledAlgorithms=MD2, MD5, RSA keySize < 1024

This is impossible because generics in Java are only considered at compile time. Thus, the Java generics are just some kind of pre-processor. However you can get the actual class of the members of the list.

I post my final way of doing it based on the accepted answer:

@SuppressWarnings("serial")
@WebServlet("/")
@MultipartConfig
public final class DataCollectionServlet extends Controller {

    private static final String UPLOAD_LOCATION_PROPERTY_KEY="upload.location";
    private String uploadsDirName;

    @Override

        super.init();
        uploadsDirName = property(UPLOAD_LOCATION_PROPERTY_KEY);
    }

    @Override

        for (Part part : parts) {
            File save = new File(uploadsDirName, getFilename(part) + "_"
                + System.currentTimeMillis());
            final String absolutePath = save.getAbsolutePath();
            log.debug(absolutePath);
            part.write(absolutePath);

            if (cd.trim().startsWith("filename")) {
                String filename = cd.substring(cd.indexOf('=') + 1).trim()
                        .replace("\"", "");
                return filename.substring(filename.lastIndexOf('/') + 1)
                        .substring(filename.lastIndexOf('\\') + 1); // MSIE fix.
            }
        }
        return null;
    }

where :

    static ServletContext sc;
    Logger log;
    // private

    private static final String PROPERTIES_PATH = "WEB-INF/app.properties";

    @Override
    public void init() throws ServletException {
        super.init();

        if (sc == null) sc = getServletContext();
        log = LoggerFactory.getLogger(this.getClass());
        try {

upload.location=C:/_/

HTH and if you find a bug let me know

Just want to add Matas' answer. Maybe it's obvious, but I've searched for a long time to figure out that the variable is accessible only inside the BEGIN-END construction, so if you need to use it in some code later, you need to put this code inside the BEGIN-END block.

Note that these blocks can be nested:

DECLARE x NUMBER;
BEGIN
    SELECT PK INTO x FROM table1 WHERE col1 = 'test';

    DECLARE y NUMBER;
    BEGIN
        SELECT PK INTO y FROM table2 WHERE col2 = x;

        INSERT INTO table2 (col1, col2)
        SELECT y,'text'
        FROM dual
        WHERE exists(SELECT * FROM table2);

        COMMIT;
    END;
END;

I would like to re-structure the statement that you mentioned which is:

This means that the state as consumed by your target component can have a wildly different structure from the state as it is stored on your store

You can say that the state consumed by your target component has a small portion of the state that is stored on the redux store. In other words, the state consumed by your component would be the sub-set of the state of the redux store.

As far as understanding the connect() method is concerned, it's fairly simple! connect() method has the power to add new props to your component and even override existing props. It is through this connect method that we can access the state of the redux store as well which is thrown to us by the Provider. A combination of which works in your favor and you get to add the state of your redux store to the props of your component.

Above is some theory and I would suggest you look at this video once to understand the syntax better.

better use quoted `data` and `date`. AFAIR these may be reserved words my version is:

INSERT INTO `table` ( `data` , `date` ) VALUES('".$date."',NOW()+INTERVAL 1 DAY);

Try sending the data like this:

var data = {};
data.album = this.title;

Then you can access it like

$_POST['album']

Notice not a 'GET'

I find that using Apache Commons IO makes my life much easier.

String source = "This is the source of my input stream";
InputStream in = org.apache.commons.io.IOUtils.toInputStream(source, "UTF-8");

You may find that the library also offer many other shortcuts to commonly done tasks that you may be able to use in your project.

Deprecated solution

valueLink/checkedLink are deprecated from core React, because it is confusing some users. This answer won't work if you use a recent version of React. But if you like it, you can easily emulate it by creating your own Input component

Old answer content:

What you want to achieve can be much more easily achieved using the 2-way data binding helpers of React.

var Hello = React.createClass({
    mixins: [React.addons.LinkedStateMixin],
    getInitialState: function() {
        return {input1: 0, input2: 0};
    },

    render: function() {
        var total = this.state.input1 + this.state.input2;
        return (
            <div>{total}<br/>
                <input type="text" valueLink={this.linkState('input1')} />;
                <input type="text" valueLink={this.linkState('input2')} />;
            </div>
        );
    }

});

React.renderComponent(<Hello />, document.getElementById('content'));

Easy right?

You can even implement your own mixin

Also, you can create your own outerHeight for HTML elements. I don't know if it works in IE, but it works in Chrome. Perhaps, you can enhance the code below using currentStyle, suggested in the answer above.

Object.defineProperty(Element.prototype, 'outerHeight', {
    'get': function(){
        var height = this.clientHeight;
        var computedStyle = window.getComputedStyle(this); 
        height += parseInt(computedStyle.marginTop, 10);
        height += parseInt(computedStyle.marginBottom, 10);
        height += parseInt(computedStyle.borderTopWidth, 10);
        height += parseInt(computedStyle.borderBottomWidth, 10);
        return height;
    }
});

This piece of code allow you to do something like this:

document.getElementById('foo').outerHeight

According to caniuse.com, getComputedStyle is supported by main browsers (IE, Chrome, Firefox).

> but I don't know how to retrieve the list members from the hash in alphabetical order.

Not really your main question, but for future reference Rod's answer using sorted can be used for traversing a dict's keys in sorted order:

for key in sorted(my_dict.keys()):
   print key, my_dict[key]
   ...

and also because tuple's are ordered by the first member of the tuple, you can do the same with items:

for key, val in sorted(my_dict.items()):
    print key, val
    ...

In a linked question, there's some Objective-C code to get the mime type for a file URL. I've created a Swift extension based on that Objective-C code to get the mime type:

import Foundation
import MobileCoreServices

extension URL {
    var mimeType: String? {
        guard self.pathExtension.count != 0 else {
            return nil
        }

        let pathExtension = self.pathExtension as CFString
        if let preferredIdentifier = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension, nil) {
            guard let mimeType = UTTypeCopyPreferredTagWithClass(preferredIdentifier.takeRetainedValue(), kUTTagClassMIMEType) else {
                return nil
            }
            return mimeType.takeRetainedValue() as String
        }

        return nil
    }
}

No. Pylint doesn't currently let you discriminate between doc-string warnings.

However, you can use Flake8 for all Python code checking along with the doc-string extension to ignore this warning.

Install the doc-string extension with pip (internally, it uses pydocstyle).

pip install flake8_docstrings

You can then just use the --ignore D100 switch. For example, flake8 file.py --ignore D100

Run this

    for (Method m : sex.class.getDeclaredMethods()) {
        System.out.println(m);
    }

you will see

public static test.Sex test.Sex.valueOf(java.lang.String)
public static test.Sex[] test.Sex.values()

These are all public methods that "sex" class has. They are not in the source code, javac.exe added them

Notes:

1. never use sex as a class name, it's difficult to read your code, we use Sex in Java

2. when facing a Java puzzle like this one, I recommend to use a bytecode decompiler tool (I use Andrey Loskutov's bytecode outline Eclispe plugin). This will show all what's inside a class

This question already has an answer, but I just want to add that in Windows there is Windows Subsystem for Linux WSL.

So for example if you want to check if you have service named Elasicsearch that is in status running you can do something like the snippet below in powershell

net start | grep Elasticsearch

According to the book PHP and MySQL for Dynamic Web Sites (4th edition)

Example:

$r = mysqli_query($dbc, $q);

For simple queries like INSERT, UPDATE, DELETE, etc. (which do not return records), the $r variable—short for result—will be either TRUE or FALSE, depending upon whether the query executed successfully.

Keep in mind that “executed successfully” means that it ran without error; it doesn’t mean that the query’s execution necessarily had the desired result; you’ll need to test for that.

Then how to test?

While the mysqli_num_rows() function will return the number of rows generated by a SELECT query, mysqli_affected_rows() returns the number of rows affected by an INSERT, UPDATE, or DELETE query. It’s used like so:

$num = mysqli_affected_rows($dbc);

Unlike mysqli_num_rows(), the one argument the function takes is the database connection ($dbc), not the results of the previous query ($r).

If you want to write unit per meter (m^-1), use $m^{-1}$), which means -1 inbetween {}

Example: plt.ylabel("Specific Storage Values ($m^{-1}$)", fontsize = 12 )

This has happened to me multiple times. I have used Amazon Linux AMI 2013.09.2 and Ubuntu Server 12.04.3 LTS which are both on the free tier.

Every time I have launched an instance I have permission denied show up. I haven't verified this but my theory is that the server is not completely set up before I try to ssh into it. After a few tries with permission denied, I wait a few minutes and then I am able to connect. If you are having this problem I suggest waiting five minutes and trying again.

$string = ' Test me more ';
preg_match('/\b\w+\b/i', $string, $result); // Test
echo $result;

/* You could use [a-zA-Z]+ instead of \w+ if wanted only alphabetical chars. */
$string = ' Test me more ';
preg_match('/\b[a-zA-Z]+\b/i', $string, $result); // Test
echo $result;
