I started studying graphs recently. I wrote a piece of code in java that could determine if a graph has cycles. I used DFT to find cycles in the graph. Instead of recurssion I used a stack to traverse the graph.

At a high level DFT using a stack is done in the following steps

1. Visit a Node
2. If the node is not in the visited list add it to the list and push it to the top of the stack
3. Mark the node at the top of the stack as the current node.
4. Repeat the above for each adjacent node of the current node
5. If all the nodes have been visited pop the current node off the stack

I performed a DFT from each node of the Graph and during the traversal if I encountered a vertex that I visited earlier, I checked if the vertex had a stack depth greater than one. I also checked if a node had an edge to itself and if there were multiple edges between nodes. The stack version that I originally wrote was not very elegant. I read the pseudo code of how it could be done using recursion and it was neat. Here is a java implementation. The LinkedList array represents a graph. with each node and it's adjacent vertices denoted by the index of the array and each item respectively

class GFG {
Boolean isCyclic(int V, LinkedList<Integer>[] alist) {
    List<Integer> visited = new ArrayList<Integer>();
    for (int i = 0; i < V; i++) {
        if (!visited.contains(i)) {
            if (isCyclic(i, alist, visited, -1))
                return true;
        }
    }
    return false;
}

Boolean isCyclic(int vertex, LinkedList<Integer>[] alist, List<Integer> visited, int parent) {
    visited.add(vertex);
    for (Iterator<Integer> iterator = alist[vertex].iterator(); iterator.hasNext();) {
        int element = iterator.next();
        if (!visited.contains(element)) {
            if (isCyclic(element, alist, visited, vertex))
                return true;
        } else if (element != parent)
            return true;
    }
    return false;
}

}

Only public static void main(String[] args) counts. This is the only signature considered to be the true main() (as the program entry point, I mean).

android:inputType="number" or android:inputType="phone". You can keep this. You will get the keyboard containing numbers. For further details on different types of keyboard, check this link.

I think it is possible only if you create your own soft keyboard. Or try this android:inputType="number|textVisiblePassword. But it still shows other characters. Besides you can keep android:digits="0123456789" to allow only numbers in your edittext. Or if you still want the same as in image, try combining two or more features with | separator and check your luck, but as per my knowledge you have to create your own keypad to get exactly like that..

The following code can help you to understand some real world use of predicates (Combined with named iterators).

namespace Predicate
{
    class Person
    {
        public int Age { get; set; }
    }
    class Program
    {
        static void Main(string[] args)
        {
            foreach (Person person in OlderThan(18))
            {
                Console.WriteLine(person.Age);
            }
        }

        static IEnumerable<Person> OlderThan(int age)
        {
            Predicate<Person> isOld = x => x.Age > age;
            Person[] persons = { new Person { Age = 10 }, new Person { Age = 20 }, new Person { Age = 19 } };

            foreach (Person person in persons)
                if (isOld(person)) yield return person;
        }
    }
}

You need to use a concrete class and not an Abstract class while deserializing. if the Abstract class has several implementations then, in that case, you can use it as below-

  @JsonTypeInfo( use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "type")
    @JsonSubTypes({ 
      @Type(value = Bike.class, name = "bike"), 
      @Type(value = Auto.class, name = "auto"), 
      @Type(value = Car.class, name = "car")
    })
    public abstract class Vehicle {
        // fields, constructors, getters, setters
    }

There actually doesn't seem to be a lot of explanation on this subject apparently but the exit codes are supposed to be used to give an indication on how the thread exited, 0 tends to mean that it exited safely whilst anything else tends to mean it didn't exit as expected. But then this exit code can be set in code by yourself to completely overlook this.

The closest link I could find to be useful for more information is this

Quote from above link:

What ever the method of exiting, the integer that you return from your process or thread must be values from 0-255(8bits). A zero value indicates success, while a non zero value indicates failure. Although, you can attempt to return any integer value as an exit code, only the lowest byte of the integer is returned from your process or thread as part of an exit code. The higher order bytes are used by the operating system to convey special information about the process. The exit code is very useful in batch/shell programs which conditionally execute other programs depending on the success or failure of one.

From the Documentation for GetEXitCodeThread

Important The GetExitCodeThread function returns a valid error code defined by the application only after the thread terminates. Therefore, an application should not use STILL_ACTIVE (259) as an error code. If a thread returns STILL_ACTIVE (259) as an error code, applications that test for this value could interpret it to mean that the thread is still running and continue to test for the completion of the thread after the thread has terminated, which could put the application into an infinite loop.

My understanding of all this is that the exit code doesn't matter all that much if you are using threads within your own application for your own application. The exception to this is possibly if you are running a couple of threads at the same time that have a dependency on each other. If there is a requirement for an outside source to read this error code, then you can set it to let other applications know the status of your thread.

There really isn't a single "answer" to this question, but there are definitely some helpful concepts that can help you to come to a decision.

The first question that needs to be answered in your use case is "Do I want to use the system Python?" If you want to use the Python distributed with your operating system, then using the apt-get install method may be just fine. Depending on the operating system distribution method though, you still have to ask some more questions, such as "Do I want to install multiple versions of this package?" If the answer is yes, then it is probably not a good idea to use something like apt. Dpkg pretty much will just untar an archive at the root of the filesystem, so it is up to the package maintainer to make sure the package installs safely under very little assumptions. In the case of most debian packages, I would assume (someone can feel free to correct me here) that they simply untar and provide a top level package.

For example, say the package is "virtualenv", you'd end up with /usr/lib/python2.x/site-packages/virtualenv. If you install it with easy_install you'd get something like /usr/lib/python2.x/site-packages/virtualenv.egg-link that might point to /usr/lib/python2.x/site-packages/virtualenv-1.2-2.x.egg which may be a directory or zipped egg. Pip does something similar although it doesn't use eggs and instead will place the top level package directly in the lib directory.

I might be off on the paths, but the point is that each method takes into account different needs. This is why tools like virtualenv are helpful as they allow you to sandbox your Python libraries such that you can have any combination you need of libraries and versions.

Setuptools also allows installing packages as multiversion which means there is not a singular module_name.egg-link created. To import those packages you need to use pkg_resources and the __import__ function.

Going back to your original question, if you are happy with the system python and plan on using virtualenv and pip to build environments for different applications, then installing virtualenv and / or pip at the system level using apt-get seems totally appropriate. One word of caution though is that if you plan on upgrading your distributions Python, that may have a ripple effect through your virtualenvs if you linked back to your system site packages.

I should also mention that none of these options is inherently better than the others. They simply take different approaches. Using the system version is an excellent way to install Python applications, yet it can be a very difficult way to develop with Python. Easy install and setuptools is very convenient in a world without virtualenv, but if you need to use different versions of the same library, then it also become rather unwieldy. Pip and virtualenv really act more like a virtual machine. Instead of taking care to install things side by side, you just create an whole new environment. The downside here is that 30+ virtualenvs later you might have used up quite bit of diskspace and cluttered up your filesystem.

As you can see, with the many options it is difficult to say which method to use, but with a little investigation into your use cases, you should be able to find a method that works.

ajavascript have two type of annotation for fetching javascript Object properties:

Obj = {};

1) (.) annotation eg. Obj.id this will only work if the object already have a property with name 'id'

2) ([]) annotation eg . Obj[id] here if the object does not have any property with name 'id',it will create a new property with name 'id'.

so for below example:

A new property will be created always when you write Obj[name]. And if the property already exist with the same name it will override it.

const obj = {}
    jQuery(itemsFromDom).each(function() {
      const element = jQuery(this)
      const name = element.attr('id')
      const value = element.attr('value')
      // This will work
      obj[name]= value;
    })

Given this example url:

http://www.example.com/some-dir/yourpage.php?q=bogus&n=10

$_SERVER['REQUEST_URI'] will give you:

/some-dir/yourpage.php?q=bogus&n=10

Whereas $_GET['q'] will give you:

bogus

In other words, $_SERVER['REQUEST_URI'] will hold the full request path including the querystring. And $_GET['q'] will give you the value of parameter q in the querystring.

I don't think it actually does much, it looks like it's just a cache for string literals. If you have multiple Strings who's values are the same, they'll all point to the same string literal in the string pool.

String s1 = "Arul"; //case 1 
String s2 = "Arul"; //case 2 

In case 1, literal s1 is created newly and kept in the pool. But in case 2, literal s2 refer the s1, it will not create new one instead.

if(s1 == s2) System.out.println("equal"); //Prints equal. 

String n1 = new String("Arul"); 
String n2 = new String("Arul"); 
if(n1 == n2) System.out.println("equal"); //No output.

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

@Alan's answer will do what you're looking for, but this solution fails when you use the responsive capabilities of Bootstrap. In your case, you're using the xs sizes so you won't notice, but if you used anything else (e.g. col-sm, col-md, etc), you'd understand.

Another approach is to play with margins and padding. See the updated fiddle: http://jsfiddle.net/jz8j247x/1/

.left-side {
  background-color: blue;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.something {
  height: 100%;
  background-color: red;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.row {
  background-color: green;
  overflow: hidden;
}

The money datatype on SQL Server has four digits after the decimal.

From SQL Server 2000 Books Online:

Monetary data represents positive or negative amounts of money. In Microsoft® SQL Server™ 2000, monetary data is stored using the money and smallmoney data types. Monetary data can be stored to an accuracy of four decimal places. Use the money data type to store values in the range from -922,337,203,685,477.5808 through +922,337,203,685,477.5807 (requires 8 bytes to store a value). Use the smallmoney data type to store values in the range from -214,748.3648 through 214,748.3647 (requires 4 bytes to store a value). If a greater number of decimal places are required, use the decimal data type instead.

I think you can find it usefull

http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-two-datasources

It shows how to define multiple datasources & assign one of them as primary.

Here is a rather full example, also contains distributes transactions - if you need it.

http://fabiomaffioletti.me/blog/2014/04/15/distributed-transactions-multiple-databases-spring-boot-spring-data-jpa-atomikos/

What you need is to create 2 configuration classes, separate the model/repository packages etc to make the config easy.

Also, in above example, it creates the data sources manually. You can avoid this using the method on spring doc, with @ConfigurationProperties annotation. Here is an example of this:

I solved this exception by changing the target sdk version from 19 onwards kitkat version AndroidManifest.xml.

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

use: https://registry.npmjs.org/ Make sure you are trying to connect to:

registry.npmjs.org

if there is no error,try to clear cache

npm cache clean --force

then try

npm install

even you have any error

npm config set registry https://registry.npmjs.org/

then try

npm install -g @angular/cli

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

To specify a variable is an array of objects:

$needles = getAllNeedles();
/* @var $needles Needle[] */
$needles[1]->...                        //codehinting works

This works in Netbeans 7.2 (I'm using it)

Works also with:

$needles = getAllNeedles();
/* @var $needles Needle[] */
foreach ($needles as $needle) {
    $needle->...                        //codehinting works
}

Therefore use of declaration inside the foreach is not necessary.

It's been a lot of times and there are lots of valid answers, but the following code block seems to work:

my_object = SqlAlchemyModel()
my_serializable_obj = my_object.__dict__
del my_serializable_obj["_sa_instance_state"]
print(jsonify(my_serializable_object))

I'm aware that this is not a perfect solution, nor as elegant as the others, however for those who want o quick fix, they might try this.

If you are on php 5.4+, it is cleaner to use session_status():

if (session_status() == PHP_SESSION_ACTIVE) {
  echo 'Session is active';
}

• PHP_SESSION_DISABLED if sessions are disabled.
• PHP_SESSION_NONE if sessions are enabled, but none exists.
• PHP_SESSION_ACTIVE if sessions are enabled, and one exists.

http://jsfiddle.net/v8aWF/

Worked out a fiddle. Do check it out

(function() {
    var oJson = {
        "name": "", 
        "skills": "", 
        "jobtitle": "Entwickler", 
        "res_linkedin": "GwebSearch"
    }
    alert(oJson.jobtitle);
})();

You can with regular expressions Input Patterns (check browser compatibility)

<input id="password" name="password" type="password" pattern="^\S{6,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Must have at least 6 characters' : ''); if(this.checkValidity()) form.password_two.pattern = this.value;" placeholder="Password" required>

<input id="password_two" name="password_two" type="password" pattern="^\S{6,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Please enter the same Password as above' : '');" placeholder="Verify Password" required>

Once you have the packages setup, you'll need to create either an app.config or web.config and add something like the following:

<configuration>
  <appSettings>
    <add key="key" value="value"/>
  </appSettings>
</configuration>

1.) Create an arraylist of appropriate type, in this case i.e String

2.) Create a JSONObject while passing your string to JSONObject constructor as input

• As JSONObject notation is represented by braces i.e {}
• Where as JSONArray notation is represented by square brackets i.e []

3.) Retrieve JSONArray from JSONObject (created at 2nd step) using "interests" as index.

4.) Traverse JASONArray using loops upto the length of array provided by length() function

5.) Retrieve your JSONObjects from JSONArray using getJSONObject(index) function

6.) Fetch the data from JSONObject using index '"interestKey"'.

Note : JSON parsing uses the escape sequence for special nested characters if the json response (usually from other JSON response APIs) contains quotes (") like this

`"{"key":"value"}"`

should be like this

`"{\"key\":\"value\"}"`

so you can use JSONParser to achieve escaped sequence format for safety as

JSONParser parser = new JSONParser();
JSONObject json = (JSONObject) parser.parse(inputString);

Code :

JSONParser parser = new JSONParser();
String response = "{interests : [{interestKey:Dogs}, {interestKey:Cats}]}";

JSONObject jsonObj = (JSONObject) parser.parse(response);

or

JSONObject jsonObj = new JSONObject("{interests : [{interestKey:Dogs}, {interestKey:Cats}]}");

List<String> interestList = new ArrayList<String>();

JSONArray jsonArray = jsonObj.getJSONArray("interests");

for(int i = 0 ; i < jsonArray.length() ; i++){
    interestList.add(jsonArray.getJSONObject(i).optString("interestKey"));
}

Note : Sometime you may see some exceptions when the values are not available in appropriate type or is there is no mapping key so in those cases when you are not sure about the presence of value so use optString, optInt, optBoolean etc which will simply return the default value if it is not present and even try to convert value to int if it is of string type and vice-versa so Simply No null or NumberFormat exceptions at all in case of missing key or value

From docs

Get an optional string associated with a key. It returns the defaultValue if there is no such key.

 public String optString(String key, String defaultValue) {

  String missingKeyValue = json_data.optString("status","N/A");
  // note there is no such key as "status" in response
  // will return "N/A" if no key found 

or To get empty string i.e "" if no key found then simply use

  String missingKeyValue = json_data.optString("status");
  // will return "" if no key found where "" is an empty string

The difference between the two is best brought in what seems a necessary and sufficient definition of the dependencyManagement element available in Maven website docs:

dependencyManagement

"Default dependency information for projects that inherit from this one. The dependencies in this section are not immediately resolved. Instead, when a POM derived from this one declares a dependency described by a matching groupId and artifactId, the version and other values from this section are used for that dependency if they were not already specified." [ https://maven.apache.org/ref/3.6.1/maven-model/maven.html ]

It should be read along with some more information available on a different page:

“..the minimal set of information for matching a dependency reference against a dependencyManagement section is actually {groupId, artifactId, type, classifier}. In many cases, these dependencies will refer to jar artifacts with no classifier. This allows us to shorthand the identity set to {groupId, artifactId}, since the default for the type field is jar, and the default classifier is null.” [https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html ]

Thus, all the sub-elements (scope, exclusions etc.,) of a dependency element--other than groupId, artifactId, type, classifier, not just version--are available for lockdown/default at the point (and thus inherited from there onward) you specify the dependency within a dependencyElement. If you’d specified a dependency with the type and classifier sub-elements (see the first-cited webpage to check all sub-elements) as not jar and not null respectively, you’d need {groupId, artifactId, classifier, type} to reference (resolve) that dependency at any point in an inheritance originating from the dependencyManagement element. Else, {groupId, artifactId} would suffice if you do not intend to override the defaults for classifier and type (jar and null respectively). So default is a good keyword in that definition; any sub-element(s) (other than groupId, artifactId, classifier and type, of course) explicitly assigned value(s) at the point you reference a dependency override the defaults in the dependencyManagement element.

So, any dependency element outside of dependencyManagement, whether as a reference to some dependencyManagement element or as a standalone is immediately resolved (i.e. installed to the local repository and available for classpaths).

That's not possible. localhost always defaults to the loopback device on the local operating system.
As your virtual machine runs its own operating system it has its own loopback device which you cannot access from the outside.

If you want to access it e.g. in a browser, connect to it using the local IP instead:

http://192.168.180.1:8000

This is just an example of course, you can find out the actual IP by issuing an ifconfig command on a shell in the guest operating system.

$_SERVER['SERVER_NAME']

It worked for me.

To pass custom params along with the button click you just need to SUBCLASS UIButton.

(ASR is on, so there's no releases in the code.)

This is myButton.h

#import <UIKit/UIKit.h>

@interface myButton : UIButton {
    id userData;
}

@property (nonatomic, readwrite, retain) id userData;

@end

This is myButton.m

#import "myButton.h"
@implementation myButton
@synthesize userData;
@end

Usage:

myButton *bt = [myButton buttonWithType:UIButtonTypeCustom];
[bt setFrame:CGRectMake(0,0, 100, 100)];
[bt setExclusiveTouch:NO];
[bt setUserData:**(insert user data here)**];

[bt addTarget:self action:@selector(touchUpHandler:) forControlEvents:UIControlEventTouchUpInside];

[view addSubview:bt];

Recieving function:

- (void) touchUpHandler:(myButton *)sender {
    id userData = sender.userData;
}

If you need me to be more specific on any part of the above code — feel free to ask about it in comments.

You can filter all characters from the string that are not printable using string.printable, like this:

>>> s = "some\x00string. with\x15 funny characters"
>>> import string
>>> printable = set(string.printable)
>>> filter(lambda x: x in printable, s)
'somestring. with funny characters'

string.printable on my machine contains:

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c

EDIT: On Python 3, filter will return an iterable. The correct way to obtain a string back would be:

''.join(filter(lambda x: x in printable, s))

My answer is basically the same as the others but I think there are two other important things to do:

1. Declare a virtual destructor in your interface or make a protected non-virtual one to avoid undefined behaviours if someone tries to delete an object of type IDemo.

2. Use virtual inheritance to avoid problems whith multiple inheritance. (There is more often multiple inheritance when we use interfaces.)

And like other answers:

• Make a class with pure virtual methods.

• Use the interface by creating another class that overrides those virtual methods.

  class IDemo
  {
      public:
          virtual void OverrideMe() = 0;
          virtual ~IDemo() {}
  }
  

  Or

  class IDemo
  {
      public:
          virtual void OverrideMe() = 0;
      protected:
          ~IDemo() {}
  }
  

  And

  class Child : virtual public IDemo
  {
      public:
          virtual void OverrideMe()
          {
              //do stuff
          }
  }
  

You could try using PHP in your web page...something like this:

<html><body>
<form method="post" name="pingform" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<h1>Host to ping:</h1>
<input type="text" name="tgt_host" value='<?php echo $_POST['tgt_host']; ?>'><br>
<input type="submit" name="submit" value="Submit" >
</form></body>
</html>
<?php

$tgt_host = $_POST['tgt_host'];
$output = shell_exec('ping -c 10 '. $tgt_host.');

echo "<html><body style=\"background-color:#0080c0\">
<script type=\"text/javascript\" language=\"javascript\">alert(\"Ping Results: " . $output . ".\");</script>
</body></html>";

?>

This is not tested so it may have typos etc...but I am confident it would work. Could be improved too...

Here's an overview from MS:

Consuming Web Services in Excel 2007

The SDK agreement and App store guidelines have been changed (circa Sept 2010).

You can now probably use any compiled language that will compile to the same static ARM object file format as Xcode produces and that will link to (only) the public API's within Apple's frameworks and libraries. However, you can not use a JIT compiled language unless you pre-compile all object code before submission to Apple for review.

You can use any interpreted language, as long as you embed the interpreter, and do not allow the interpreter or the app to download and run any interpretable code other than code built into the app bundle before submission to Apple for review, or source code typed-in by the user.

Objective C and C will likely still be the most optimal programming language for anything requiring high performance and the latest API support (* see update below), as those are the languages for which Apple targets its iOS frameworks and tunes its ARM processor chipsets. Apple also supports the use of Javascript/HTML5 inside a UIWebView. Those are the only languages for which Apple has announced support. Anything else you will have to find support elsewhere.

But, if you really want, there are at least a half dozen BASIC interpreters now available in the iOS App store, so even "Stone Age" programming methodology is now allowed.

Added: (*) As of late 2014, one can also develop apps using Apple's new Swift programming language. As of early 2015, submitted binaries must include 64-bit (arm64) support.

The number of parameters is 7850 because with every hidden unit you have 784 input weights and one weight of connection with bias. This means that every hidden unit gives you 785 parameters. You have 10 units so it sums up to 7850.

The role of this additional bias term is really important. It significantly increases the capacity of your model. You can read details e.g. here Role of Bias in Neural Networks.

You can also use the required module.

require('./componentName.css');
const React = require('react');

I'd probably change your example to look like this:

<ul ng-repeat="task in tasks">
  <li ng-mouseover="enableEdit(task)" ng-mouseleave="disableEdit(task)">{{task.name}}</li>
  <span ng-show="task.editable"><a>Edit</a></span>
</ul>

//js
$scope.enableEdit = function(item){
  item.editable = true;
};

$scope.disableEdit = function(item){
  item.editable = false;
};

I know it's a subtle difference, but makes the domain a little less bound to UI actions. Mentally it makes it easier to think about an item being editable rather than having been moused over.

Example jsFiddle.

Just add the following line to the <head> section of your HTML file:

<link rel="icon" href="data:,">

Features of this solution:

• 100% valid HTML5
• very short
• does not incur any quirks from IE 8 and older
• does not make the browser interpret the current HTML code as favicon (which would be the case with href="#")

You want to use the TRUNCATE command.

It's very important to point out that view.layoutIfNeeded() applies to the view subviews only.

Therefore to animate the view constraint, it is important to call it on the view-to-animate superview as follows:

    topConstraint.constant = heightShift

    UIView.animate(withDuration: 0.3) {

        // request layout on the *superview*
        self.view.superview?.layoutIfNeeded()
    }

An example for a simple layout as follows:

class MyClass {

    /// Container view
    let container = UIView()
        /// View attached to container
        let view = UIView()

    /// Top constraint to animate
    var topConstraint = NSLayoutConstraint()


    /// Create the UI hierarchy and constraints
    func createUI() {
        container.addSubview(view)

        // Create the top constraint
        topConstraint = view.topAnchor.constraint(equalTo: container.topAnchor, constant: 0)


        view.translatesAutoresizingMaskIntoConstraints = false

        // Activate constaint(s)
        NSLayoutConstraint.activate([
           topConstraint,
        ])
    }

    /// Update view constraint with animation
    func updateConstraint(heightShift: CGFloat) {
        topConstraint.constant = heightShift

        UIView.animate(withDuration: 0.3) {

            // request layout on the *superview*
            self.view.superview?.layoutIfNeeded()
        }
    }
}

SilverSkin and Anders are both correct. You can use parentheses to execute multiple commands. However, you have to make sure that the commands themselves (and their parameters) do not contain parentheses. cmd greedily searches for the first closing parenthesis, instead of handling nested sets of parentheses gracefully. This may cause the rest of the command line to fail to parse, or it may cause some of the parentheses to get passed to the commands (e.g. DEL myfile.txt)).

A workaround for this is to split the body of the loop into a separate function. Note that you probably need to jump around the function body to avoid "falling through" into it.

FOR /r %%X IN (*.txt) DO CALL :loopbody %%X
REM Don't "fall through" to :loopbody.
GOTO :EOF

:loopbody
ECHO %1
DEL %1
GOTO :EOF

create new DefaultCellEditor class :

public static class Editor_name extends DefaultCellEditor {
  public Editor_name(JCheckBox checkBox) {
   super(checkBox);
  }
  @Override
  public boolean isCellEditable(EventObject anEvent) {
    return false;
  }
}

and use setCellEditor :

JTable table = new JTable();
table.getColumn("columnName").setCellEditor(new Editor_name(new JCheckBox()));

Though my response is late, but it can still help.

lf you are using Spring Tool Suite and you still think that the JQuery file reference path is correct, then refresh your project whenever you modify the JQuery file.

You refresh by right-clicking on the project name -> refresh.

That's what solved mine.

Assuming a Windows installation, do please refer to this:

http://www.oracle-base.com/articles/misc/ManualOracleUninstall.php

• Uninstall all Oracle components using the Oracle Universal Installer (OUI).
• Run regedit.exe and delete the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE key. This contains registry entires for all Oracle products.
• Delete any references to Oracle services left behind in the following part of the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Ora* It should be pretty obvious which ones relate to Oracle.
• Reboot your machine.
• Delete the "C:\Oracle" directory, or whatever directory is your ORACLE_BASE.
• Delete the "C:\Program Files\Oracle" directory.
• Empty the contents of your "C:\temp" directory.
• Empty your recycle bin.

Calling additional attention to some great comments that were left here:

• Be careful when following anything listed here (above or below), as doing so may remove or damage any other Oracle-installed products.
• For 64-bit Windows (x64), you need also to delete the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE key from the registry.
• Clean-up by removing any related shortcuts that were installed to the Start Menu.
• Clean-up environment variables:
  • Consider removing %ORACLE_HOME%.
  • Remove any paths no longer needed from %PATH%.

This set of instructions happens to match an almost identical process that I had reverse-engineered myself over the years after a few messed-up Oracle installs, and has almost always met the need.

Note that even if the OUI is no longer available or doesn't work, simply following the remaining steps should still be sufficient.

_{(Revision #7 reverted as to not misquote the original source, and to not remove credit to the other comments that contributed to the answer. Further edits are appreciated (and then please remove this comment), if a way can be found to maintain these considerations.)}

I had the same problem: I love the resolve object, but that only works for the content of ng-view. What if you have controllers (for top-level nav, let's say) that exist outside of ng-view and which need to be initialized with data before the routing even begins to happen? How do we avoid mucking around on the server-side just to make that work?

Use manual bootstrap and an angular constant. A naiive XHR gets you your data, and you bootstrap angular in its callback, which deals with your async issues. In the example below, you don't even need to create a global variable. The returned data exists only in angular scope as an injectable, and isn't even present inside of controllers, services, etc. unless you inject it. (Much as you would inject the output of your resolve object into the controller for a routed view.) If you prefer to thereafter interact with that data as a service, you can create a service, inject the data, and nobody will ever be the wiser.

Example:

//First, we have to create the angular module, because all the other JS files are going to load while we're getting data and bootstrapping, and they need to be able to attach to it.
var MyApp = angular.module('MyApp', ['dependency1', 'dependency2']);

// Use angular's version of document.ready() just to make extra-sure DOM is fully 
// loaded before you bootstrap. This is probably optional, given that the async 
// data call will probably take significantly longer than DOM load. YMMV.
// Has the added virtue of keeping your XHR junk out of global scope. 
angular.element(document).ready(function() {

    //first, we create the callback that will fire after the data is down
    function xhrCallback() {
        var myData = this.responseText; // the XHR output

        // here's where we attach a constant containing the API data to our app 
        // module. Don't forget to parse JSON, which `$http` normally does for you.
        MyApp.constant('NavData', JSON.parse(myData));

        // now, perform any other final configuration of your angular module.
        MyApp.config(['$routeProvider', function ($routeProvider) {
            $routeProvider
              .when('/someroute', {configs})
              .otherwise({redirectTo: '/someroute'});
          }]);

        // And last, bootstrap the app. Be sure to remove `ng-app` from your index.html.
        angular.bootstrap(document, ['NYSP']);
    };

    //here, the basic mechanics of the XHR, which you can customize.
    var oReq = new XMLHttpRequest();
    oReq.onload = xhrCallback;
    oReq.open("get", "/api/overview", true); // your specific API URL
    oReq.send();
})

Now, your NavData constant exists. Go ahead and inject it into a controller or service:

angular.module('MyApp')
    .controller('NavCtrl', ['NavData', function (NavData) {
        $scope.localObject = NavData; //now it's addressable in your templates 
}]);

Of course, using a bare XHR object strips away a number of the niceties that $http or JQuery would take care of for you, but this example works with no special dependencies, at least for a simple get. If you want a little more power for your request, load up an external library to help you out. But I don't think it's possible to access angular's $http or other tools in this context.

For below Spring boot 2 version you need to use below code

server:
   context-path: abc    

And For Spring boot 2+ version use below code

server:
  servlet:
    context-path: abc

you need to cast int to str before concatenating. for that use str(temperature). Or you can print the same output using , if you don't want to convert like this.

print("the furnace is now",temperature , "degrees!")

When we open a modal it accept size as a paramenter:

Possible values for it size: sm, md, lg

$scope.openModal = function (size) {
var modal = $modal.open({
      size: size,
      templateUrl: "/app/user/welcome.html",
      ...... 
      });
}

HTML:

<button type="button" 
    class="btn btn-default" 
    ng-click="openModal('sm')">Small Modal</button>

<button type="button" 
    class="btn btn-default" 
    ng-click="openModal('md')">Medium Modal</button>

<button type="button" 
    class="btn btn-default" 
    ng-click="openModal('lg')">Large Modal</button>

If you want any specific size, add style on model HTML:

<style>.modal-dialog {width: 500px;} </style>

That is not an nginx configuration file. It is part of an nginx configuration file.

The nginx configuration file (usually called nginx.conf) will look like:

events {
    ...
}
http {
    ...
    server {
        ...
    }
}

The server block is enclosed within an http block.

Often the configuration is distributed across multiple files, by using the include directives to pull in additional fragments (for example from the sites-enabled directory).

Use sudo nginx -t to test the complete configuration file, which starts at nginx.conf and pulls in additional fragments using the include directive. See this document for more.

Another possibility - When you Build for Archive make sure your Archive choice in your scheme is set for Distribution, not Release.

Go to Product -> Edit Scheme This brings up a new dialog.

Select Archive on the left. Make sure the build configuration is Distribution.

There is a comprehensive list of tools on the PostgreSQL Wiki:

https://wiki.postgresql.org/wiki/PostgreSQL_Clients

And of course PostgreSQL itself comes with pgAdmin, a GUI tool for accessing Postgres databases.

Just to add to the accepted answer, as I found it doesn't work well if the array contents are someting like:

RUN_COMMANDS=(
  "command1 param1... paramN"
  "command2 param1... paramN"
)

In this case, each member of the array gets split, so the array the function sees is equivalent to:

RUN_COMMANDS=(
    "command1"
    "param1"
     ...
    "command2"
    ...
)

To get this case to work, the way I found is to pass the variable name to the function, then use eval:

function () {
    eval 'COMMANDS=( "${'"$1"'[@]}" )'
    for COMMAND in "${COMMANDS[@]}"; do
        echo $COMMAND
    done
}

function RUN_COMMANDS

Just my 2©

const generate = n => String(Math.ceil(Math.random() * 10**n)).padStart(n, '0')
// n being the length of the random number.

Use a parseInt() or Number() on the result if you want an integer. If you don't want the first integer to be a 0 then you could use padEnd() instead of padStart().

The easiest solution for your case - change the first line, let it do just the opposite thing:

String lower = Name.toUpperCase ();

Of course, it's worth to change its name too.

Here is a Ray Wenderlich tutorial that shows you how to use AutoLayout to dynamically size UITableViewCells. I would think it would be the same for UICollectionViewCell.

Basically, though, you end up dequeueing and configuring a prototype cell and grabbing its height. After reading this article, I decided to NOT implement this method and just write some clear, explicit sizing code.

Here's what I consider the "secret sauce" for the entire article:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    return [self heightForBasicCellAtIndexPath:indexPath];
}

- (CGFloat)heightForBasicCellAtIndexPath:(NSIndexPath *)indexPath {
    static RWBasicCell *sizingCell = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        sizingCell = [self.tableView dequeueReusableCellWithIdentifier:RWBasicCellIdentifier];
    });

    [self configureBasicCell:sizingCell atIndexPath:indexPath];
    return [self calculateHeightForConfiguredSizingCell:sizingCell];
}

- (CGFloat)calculateHeightForConfiguredSizingCell:(UITableViewCell *)sizingCell {
    [sizingCell setNeedsLayout];
    [sizingCell layoutIfNeeded];

    CGSize size = [sizingCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
    return size.height + 1.0f; // Add 1.0f for the cell separator height
}

Once you've done that, code like the following will get you going:

//  ViewController.m
#import "ViewController.h"
#import "CollectionViewCell.h"
@interface ViewController () <UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout> {

}
@property (weak, nonatomic) IBOutlet CollectionViewCell *cell;
@property (weak, nonatomic) IBOutlet UICollectionView   *collectionView;
@end
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor lightGrayColor];
    [self.collectionView registerNib:[UINib nibWithNibName:@"CollectionViewCell" bundle:nil] forCellWithReuseIdentifier:@"cell"];
}
- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    NSLog(@"viewDidAppear...");
}
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return 1;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return 50;
}
- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section {
    return 10.0f;
}
- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout minimumLineSpacingForSectionAtIndex:(NSInteger)section {
    return 10.0f;
}
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
    return [self sizingForRowAtIndexPath:indexPath];
}
- (CGSize)sizingForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *title                  = @"This is a long title that will cause some wrapping to occur. This is a long title that will cause some wrapping to occur.";
    static NSString *subtitle               = @"This is a long subtitle that will cause some wrapping to occur. This is a long subtitle that will cause some wrapping to occur.";
    static NSString *buttonTitle            = @"This is a really long button title that will cause some wrapping to occur.";
    static CollectionViewCell *sizingCell   = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        sizingCell                          = [[NSBundle mainBundle] loadNibNamed:@"CollectionViewCell" owner:self options:nil][0];
    });
    [sizingCell configureWithTitle:title subtitle:[NSString stringWithFormat:@"%@: Number %d.", subtitle, (int)indexPath.row] buttonTitle:buttonTitle];
    [sizingCell setNeedsLayout];
    [sizingCell layoutIfNeeded];
    CGSize cellSize = [sizingCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
    NSLog(@"cellSize: %@", NSStringFromCGSize(cellSize));
    return cellSize;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *title                  = @"This is a long title that will cause some wrapping to occur. This is a long title that will cause some wrapping to occur.";
    static NSString *subtitle               = @"This is a long subtitle that will cause some wrapping to occur. This is a long subtitle that will cause some wrapping to occur.";
    static NSString *buttonTitle            = @"This is a really long button title that will cause some wrapping to occur.";
    CollectionViewCell *cell                = [collectionView dequeueReusableCellWithReuseIdentifier:@"cell" forIndexPath:indexPath];
    [cell configureWithTitle:title subtitle:[NSString stringWithFormat:@"%@: Number %d.", subtitle, (int)indexPath.row] buttonTitle:buttonTitle];
    return cell;
}
@end

The code above (along with a very basic UICollectionViewCell subclass and associated XIB) gives me this:

There are three places where a file, say, can be - the (committed) tree, the index and the working copy. When you just add a file to a folder, you are adding it to the working copy.

When you do something like git add file you add it to the index. And when you commit it, you add it to the tree as well.

It will probably help you to know the three more common flags in git reset:

git reset [--<mode>] [<commit>]

This form resets the current branch head to <commit> and possibly updates the index (resetting it to the tree of <commit>) and the working tree depending on <mode>, which must be one of the following:
--soft

Does not touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

--mixed

Resets the index but not the working tree (i.e., the changed files are preserved but not marked for commit) and reports what has not been updated. This is the default action.

--hard

Resets the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded.

Now, when you do something like git reset HEAD, what you are actually doing is git reset HEAD --mixed and it will "reset" the index to the state it was before you started adding files / adding modifications to the index (via git add). In this case, no matter what the state of the working copy was, you didn't change it a single bit, but you changed the index in such a way that is now in sync with the HEAD of the tree. Whether git add was used to stage a previously committed but changed file, or to add a new (previously untracked) file, git reset HEAD is the exact opposite of git add.

git rm, on the other hand, removes a file from the working directory and the index, and when you commit, the file is removed from the tree as well. git rm --cached, however, removes the file from the index alone and keeps it in your working copy. In this case, if the file was previously committed, then you made the index to be different from the HEAD of the tree and the working copy, so that the HEAD now has the previously committed version of the file, the index has no file at all, and the working copy has the last modification of it. A commit now will sync the index and the tree, and the file will be removed from the tree (leaving it untracked in the working copy). When git add was used to add a new (previously untracked) file, then git rm --cached is the exact opposite of git add (and is pretty much identical to git reset HEAD).

Git 2.25 introduced a new command for these cases, git restore, but as of Git 2.28 it is described as “experimental” in the man page, in the sense that the behavior may change.

Your question How can I just get the file-names (with paths)

Your syntax example find . -iname "*php" -exec grep -H myString {} \;

My Command suggestion

sudo find /home -name *.php

The output from this command on my Linux OS:

compose-sample-3/html/mail/contact_me.php

As you require the filename with path, enjoy!

Do simple compare > and <.

if (dateA>dateB && dateA<dateC)
    //do something

If you care only on time:

if (dateA.TimeOfDay>dateB.TimeOfDay && dateA.TimeOfDay<dateC.TimeOfDay)
    //do something

batchfiles perform simple string substitution with variables. so, a simple

goto :language%language%
echo notfound
...

does this without any need for if.

I'v solved this error by setting the correct path variables

A lock should be considered to use, such as threading.Lock. See lock-objects for more info.

The accepted answer CAN print 10 by thread1, which is not what you want. You can run the following code to understand the bug more easily.

def thread1(threadname):
    while True:
      if a % 2 and not a % 2:
          print "unreachable."

def thread2(threadname):
    global a
    while True:
        a += 1

Using a lock can forbid changing of a while reading more than one time:

def thread1(threadname):
    while True:
      lock_a.acquire()
      if a % 2 and not a % 2:
          print "unreachable."
      lock_a.release()

def thread2(threadname):
    global a
    while True:
        lock_a.acquire()
        a += 1
        lock_a.release()

If thread using the variable for long time, coping it to a local variable first is a good choice.

Simplicity is best here. I've used a simple string replace with a regular expression, and they worked like a charm thus far. I am not a regular expression expert, but I bet you can even populate very complex objects.

var values = $(this).serialize(),
attributes = {};

values.replace(/([^&]+)=([^&]*)/g, function (match, name, value) {
    attributes[name] = value;
});

It turns out the compiler version I was using did not match the compiled version done with the coreset.o.

One was 32bit the other was 64bit. I'll leave this up in case anyone else runs into a similar problem.

You can 'learn' the size of the array automatically:

template<typename T, size_t N>
void set_data(const T (&w)[N]){
    w_.assign(w, w+N);
}

Hopefully, you can change the interface to set_data as above. It still accepts a C-style array as its first argument. It just happens to take it by reference.

How it works

[ Update: See here for a more comprehensive discussion on learning the size ]

Here is a more general solution:

template<typename T, size_t N>
void copy_from_array(vector<T> &target_vector, const T (&source_array)[N]) {
    target_vector.assign(source_array, source_array+N);
}

This works because the array is being passed as a reference-to-an-array. In C/C++, you cannot pass an array as a function, instead it will decay to a pointer and you lose the size. But in C++, you can pass a reference to the array.

Passing an array by reference requires the types to match up exactly. The size of an array is part of its type. This means we can use the template parameter N to learn the size for us.

It might be even simpler to have this function which returns a vector. With appropriate compiler optimizations in effect, this should be faster than it looks.

template<typename T, size_t N>
vector<T> convert_array_to_vector(const T (&source_array)[N]) {
    return vector<T>(source_array, source_array+N);
}

You can actually write to a named pipe using its name, btw.

Open a command shell as Administrator to get around the default "Access is denied" error:

echo Hello > \\.\pipe\PipeName

Client-side JavaScript cannot access MySQL without some kind of bridge. But the above bold statements that JavaScript is just a client-side language are incorrect -- JavaScript can run client-side and server-side, as with Node.js.

Node.js can access MySQL through something like https://github.com/sidorares/node-mysql2

Did you mean to ask whether a client-side JS app can access MySQL? I am not sure if such libraries exist, but they are possible.

EDIT: Since writing, we now have MySQL Cluster:

The MySQL Cluster JavaScript Driver for Node.js is just what it sounds like it is – it’s a connector that can be called directly from your JavaScript code to read and write your data. As it accesses the data nodes directly, there is no extra latency from passing through a MySQL Server and need to convert from JavaScript code//objects into SQL operations. If for some reason, you’d prefer it to pass through a MySQL Server (for example if you’re storing tables in InnoDB) then that can be configured.

• JSDB offers a JS interface to DBs.

• A curated set of DB packages for Node.js from sindresorhus.

You might find it useful to lookup the classes on oracle. Eg:

http://download.oracle.com/javase/1.4.2/docs/api/javax/swing/JFrame.html

There you can see that JFrame extends JComponent and JContainer.

JComponent is a a basic object that can be drawn, JContainer extends this so that you can add components to it. JPanel and JFrame both extend JComponent as you can add things to them. JFrame provides a window, whereas JPanel is just a panel that goes inside a window. If that makes sense.

Think of ! (negation operator) as "not", || (boolean-or operator) as "or" and && (boolean-and operator) as "and". See Operators and Operator Precedence.

Thus:

if(!(a || b)) {
  // means neither a nor b
}

However, using De Morgan's Law, it could be written as:

if(!a && !b) {
  // is not a and is not b
}

a and b above can be any expression (such as test == 'B' or whatever it needs to be).

Once again, if test == 'A' and test == 'B', are the expressions, note the expansion of the 1st form:

// if(!(a || b)) 
if(!((test == 'A') || (test == 'B')))
// or more simply, removing the inner parenthesis as
// || and && have a lower precedence than comparison and negation operators
if(!(test == 'A' || test == 'B'))
// and using DeMorgan's, we can turn this into
// this is the same as substituting into if(!a && !b)
if(!(test == 'A') && !(test == 'B'))
// and this can be simplified as !(x == y) is the same as (x != y)
if(test != 'A' && test != 'B')

The correct way to do it would be:

adb -s 123abc12 shell getprop

Which will give you a list of all available properties and their values. Once you know which property you want, you can give the name as an argument to getprop to access its value directly, like this:

adb -s 123abc12 shell getprop ro.product.model

The details in adb devices -l consist of the following three properties: ro.product.name, ro.product.model and ro.product.device.

Note that ADB shell ends lines with \r\n, which depending on your platform might or might not make it more difficult to access the exact value (e.g. instead of Nexus 7 you might get Nexus 7\r).

The Content hugging priority is like a Rubber band that is placed around a view. The higher the priority value, the stronger the rubber band and the more it wants to hug to its content size. The priority value can be imagined like the "strength" of the rubber band

And the Content Compression Resistance is, how much a view "resists" getting smaller The View with higher resistance priority value is the one that will resist compression.

Correct attribute value for Asp.Net MVC Core to prevent browser caching (including Internet Explorer 11) is:

[ResponseCache(Location = ResponseCacheLocation.None, NoStore = true)]

as described in Microsoft documentation:

Response caching in ASP.NET Core - NoStore and Location.None

If you like long cuts, here is another way tuple(tuple(a_m.tolist()) for a_m in a )

from numpy import array
a = array([[1, 2],
           [3, 4]])
tuple(tuple(a_m.tolist()) for a_m in a )

The output is ((1, 2), (3, 4))

Note just (tuple(a_m.tolist()) for a_m in a ) will give a generator expresssion. Sort of inspired by @norok2's comment to Greg von Winckel's answer

Download Json.NET from here http://james.newtonking.com/projects/json-net.aspx

Not really an answer to the specific question, but if there are others, like me, who are getting this error in fastAPI and end up here:

It is probably because your route response has a value that can't be JSON serialised by jsonable_encoder. For me it was WKBElement: https://github.com/tiangolo/fastapi/issues/2366

Like in the issue, I ended up just removing the value from the output.

Incorrect:

SELECT * FROM customers WHERE name LIKE '%Bob Smith%';

Instead:

select count(*)
from rearp.customers c
where c.name  LIKE '%Bob smith.8%';

select count will just query (totals)

C will link the db.table to the names row you need this to index

LIKE should be obvs

8 will call all references in DB 8 or less (not really needed but i like neatness)

polygenelubricants answer is almost perfect. It has one important bug though. It will not handle map entries where the values are the same.

This code:...

Map<String, Integer> nonSortedMap = new HashMap<String, Integer>();
nonSortedMap.put("ape", 1);
nonSortedMap.put("pig", 3);
nonSortedMap.put("cow", 1);
nonSortedMap.put("frog", 2);

for (Entry<String, Integer> entry  : entriesSortedByValues(nonSortedMap)) {
    System.out.println(entry.getKey()+":"+entry.getValue());
}

Would output:

ape:1
frog:2
pig:3

Note how our cow dissapeared as it shared the value "1" with our ape :O!

This modification of the code solves that issue:

static <K,V extends Comparable<? super V>> SortedSet<Map.Entry<K,V>> entriesSortedByValues(Map<K,V> map) {
        SortedSet<Map.Entry<K,V>> sortedEntries = new TreeSet<Map.Entry<K,V>>(
            new Comparator<Map.Entry<K,V>>() {
                @Override public int compare(Map.Entry<K,V> e1, Map.Entry<K,V> e2) {
                    int res = e1.getValue().compareTo(e2.getValue());
                    return res != 0 ? res : 1; // Special fix to preserve items with equal values
                }
            }
        );
        sortedEntries.addAll(map.entrySet());
        return sortedEntries;
    }

I think this is what you want, I already tested this code and works

The tools used are: (all these tools can be downloaded as Nuget packages)

http://fluentassertions.codeplex.com/

http://autofixture.codeplex.com/

http://code.google.com/p/moq/

https://nuget.org/packages/AutoFixture.AutoMoq

var fixture = new Fixture().Customize(new AutoMoqCustomization());
var myInterface = fixture.Freeze<Mock<IFileConnection>>();

var sut = fixture.CreateAnonymous<Transfer>();

myInterface.Setup(x => x.Get(It.IsAny<string>(), It.IsAny<string>()))
        .Throws<System.IO.IOException>();

sut.Invoking(x => 
        x.TransferFiles(
            myInterface.Object, 
            It.IsAny<string>(), 
            It.IsAny<string>()
        ))
        .ShouldThrow<System.IO.IOException>();

Edited:

Let me explain:

When you write a test, you must know exactly what you want to test, this is called: "subject under test (SUT)", if my understanding is correctly, in this case your SUT is: Transfer

So with this in mind, you should not mock your SUT, if you substitute your SUT, then you wouldn't be actually testing the real code

When your SUT has external dependencies (very common) then you need to substitute them in order to test in isolation your SUT. When I say substitute I'm referring to use a mock, dummy, mock, etc depending on your needs

In this case your external dependency is IFileConnection so you need to create mock for this dependency and configure it to throw the exception, then just call your SUT real method and assert your method handles the exception as expected

• var fixture = new Fixture().Customize(new AutoMoqCustomization());: This linie initializes a new Fixture object (Autofixture library), this object is used to create SUT's without having to explicitly have to worry about the constructor parameters, since they are created automatically or mocked, in this case using Moq

• var myInterface = fixture.Freeze<Mock<IFileConnection>>();: This freezes the IFileConnection dependency. Freeze means that Autofixture will use always this dependency when asked, like a singleton for simplicity. But the interesting part is that we are creating a Mock of this dependency, you can use all the Moq methods, since this is a simple Moq object

• var sut = fixture.CreateAnonymous<Transfer>();: Here AutoFixture is creating the SUT for us

• myInterface.Setup(x => x.Get(It.IsAny<string>(), It.IsAny<string>())).Throws<System.IO.IOException>(); Here you are configuring the dependency to throw an exception whenever the Get method is called, the rest of the methods from this interface are not being configured, therefore if you try to access them you will get an unexpected exception

• sut.Invoking(x => x.TransferFiles(myInterface.Object, It.IsAny<string>(), It.IsAny<string>())).ShouldThrow<System.IO.IOException>();: And finally, the time to test your SUT, this line uses the FluenAssertions library, and it just calls the TransferFiles real method from the SUT and as parameters it receives the mocked IFileConnection so whenever you call the IFileConnection.Get in the normal flow of your SUT TransferFiles method, the mocked object will be invoking throwing the configured exception and this is the time to assert that your SUT is handling correctly the exception, in this case, I am just assuring that the exception was thrown by using the ShouldThrow<System.IO.IOException>() (from the FluentAssertions library)

There is no work-around for this aside from ditching the select element.

Here is (low and dirty) workaround in case you need to use ajax or some feature which you cannot use when making link manually (using tag):

<%= Html.ActionLink("LinkTextToken", "ActionName", "ControllerName").ToHtmlString().Replace("LinkTextToken", "Refresh <span class='large sprite refresh'></span>")%>

You can use any text instead of 'LinkTextToken', it is there only to be replaced, it is only important that it does not occur anywhere else inside actionlink.

The standard Object implementation (ES5.1 Object Internal Properties and Methods) does not require an Object to track its number of keys/properties, so there should be no standard way to determine the size of an Object without explicitly or implicitly iterating over its keys.

So here are the most commonly used alternatives:

1. ECMAScript's Object.keys()

Object.keys(obj).length; Works by internally iterating over the keys to compute a temporary array and returns its length.

• Pros - Readable and clean syntax. No library or custom code required except a shim if native support is unavailable
• Cons - Memory overhead due to the creation of the array.

2. Library-based solutions

Many library-based examples elsewhere in this topic are useful idioms in the context of their library. From a performance viewpoint, however, there is nothing to gain compared to a perfect no-library code since all those library methods actually encapsulate either a for-loop or ES5 Object.keys (native or shimmed).

3. Optimizing a for-loop

The slowest part of such a for-loop is generally the .hasOwnProperty() call, because of the function call overhead. So when I just want the number of entries of a JSON object, I just skip the .hasOwnProperty() call if I know that no code did nor will extend Object.prototype.

Otherwise, your code could be very slightly optimized by making k local (var k) and by using prefix-increment operator (++count) instead of postfix.

var count = 0;
for (var k in myobj) if (myobj.hasOwnProperty(k)) ++count;

Another idea relies on caching the hasOwnProperty method:

var hasOwn = Object.prototype.hasOwnProperty;
var count = 0;
for (var k in myobj) if (hasOwn.call(myobj, k)) ++count;

Whether this is faster or not on a given environment is a question of benchmarking. Very limited performance gain can be expected anyway.

In MySQL Workbench 6, commands have been repositioned as the "Server Administration" tab is gone.

You now find the option "Data Export" under the "Management" section when you open a standard server connection.

In Bootstrap 4

In my case I have just changed the .navbar min-height and the links font-size and it decreased the navbar.

For example:

.navbar{
    min-height:12px;
}
.navbar  a {
    font-size: 11.2px;
}

And this also worked for increasing the navbar height.

This also helps to change the navbar size when scrolling down the browser.

try to use this

<RadioGroup
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"       
    android:orientation="horizontal"
>    
    <RadioButton
        android:id="@+id/standard_delivery"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/Standard_delivery"
        android:checked="true"
        android:layout_marginTop="4dp"
        android:layout_marginLeft="15dp"
        android:textSize="12dp"
        android:onClick="onRadioButtonClicked"   
    />

    <RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/Midnight_delivery"
        android:checked="false"
        android:layout_marginRight="15dp"
        android:layout_marginTop="4dp"
        android:textSize="12dp"
        android:onClick="onRadioButtonClicked"
        android:id="@+id/midnight_delivery"
    />    
</RadioGroup>

this is java class

public void onRadioButtonClicked(View view) {
        // Is the button now checked?
        boolean checked = ((RadioButton) view).isChecked();

        // Check which radio button was clicked
        switch(view.getId()) {
            case R.id.standard_delivery:
                if (checked)
                    Toast.makeText(DishActivity.this," standard delivery",Toast.LENGTH_LONG).show();
                    break;
            case R.id.midnight_delivery:
                if (checked)
                    Toast.makeText(DishActivity.this," midnight delivery",Toast.LENGTH_LONG).show();
                    break;
        }
    }

You can also use list comprehension to create set.

s = {i for i in range(5)}

docker rmi $(docker images -q) --force

Use find. Seriously, it is the best way because then you can really see what files it's operating on:

find . -name "*.sql" -exec grep -H "slow" {} \;

Note, the -H is mac-specific, it shows the filename in the results.

You can declare as many Exceptions as you want for your interface method. But the class you gave in your question is invalid. It should read

public class MyClass implements MyInterface {
  public void find(int x) throws A_Exception, B_Exception{
    ----
    ----
    ---
  }
}

Then an interface would look like this

public interface MyInterface {
  void find(int x) throws A_Exception, B_Exception;
}

You don't necessarily need to have the parameters inside the URL.

For instance, with:

$stateProvider
.state('home', {
  url: '/',
  views: {
    '': {
      templateUrl: 'home.html',
      controller: 'MainRootCtrl'

    },
  },
  params: {
    foo: null,
    bar: null
  }
})

You will be able to send parameters to the state, using either:

$state.go('home', {foo: true, bar: 1});
// or
<a ui-sref="home({foo: true, bar: 1})">Go!</a>

Of course, if you reload the page once on the home state, you will loose the state parameters, as they are not stored anywhere.

A full description of this behavior is documented here, under the params row in the state(name, stateConfig) section.

These may not solve exactly your "real-world problems", but perhaps something useful ...

Our web site includes PhoneGap and jQuery Mobile tutorials for a media player, barcode scanner, google maps, and OAuth.

Also, my github page has code, but no tutorial, for two apps:

• AppLaudApp - a run-control, debugging enabling, download complementary app to a cloud IDE
• NameTrendz - an app developed in at Android Dev Camp to do a bunch of queries about popular name data. The PhoneGap and jQuery Mobile versions are from March 2011.

This could also be an issue of building the code using a 64 bit configuration. You can try to select x86 as the build platform which can solve this issue. To do this right-click the solution and select Configuration Manager From there you can change the Platform of the project using the 32-bit .dll to x86

There is really no advantage in using Object.create(...) over new object.

Those advocating this method generally state rather ambiguous advantages: "scalability", or "more natural to JavaScript" etc.

However, I have yet to see a concrete example that shows that Object.create has any advantages over using new. On the contrary there are known problems with it. Sam Elsamman describes what happens when there are nested objects and Object.create(...) is used:

var Animal = {
    traits: {},
}
var lion = Object.create(Animal);
lion.traits.legs = 4;
var bird = Object.create(Animal);
bird.traits.legs = 2;
alert(lion.traits.legs) // shows 2!!!

This occurs because Object.create(...) advocates a practice where data is used to create new objects; here the Animal datum becomes part of the prototype of lion and bird, and causes problems as it is shared. When using new the prototypal inheritance is explicit:

function Animal() {
    this.traits = {};
}

function Lion() { }
Lion.prototype = new Animal();
function Bird() { }
Bird.prototype = new Animal();

var lion = new Lion();
lion.traits.legs = 4;
var bird = new Bird();
bird.traits.legs = 2;
alert(lion.traits.legs) // now shows 4

Regarding, the optional property attributes that are passed into Object.create(...), these can be added using Object.defineProperties(...).

wait is defined in Object, and not it Thread. The monitor on Thread is a little unpredictable.

Although all Java objects have monitors, it is generally better to have a dedicated lock:

private final Object lock = new Object();

You can get slightly easier to read diagnostics, at a small memory cost (about 2K per process) by using a named class:

private static final class Lock { }
private final Object lock = new Lock();

In order to wait or notify/notifyAll an object, you need to be holding the lock with the synchronized statement. Also, you will need a while loop to check for the wakeup condition (find a good text on threading to explain why).

synchronized (lock) {
    while (!isWakeupNeeded()) {
        lock.wait();
    }
}

To notify:

synchronized (lock) {
    makeWakeupNeeded();
    lock.notifyAll();
}

It is well worth getting to understand both Java language and java.util.concurrent.locks locks (and java.util.concurrent.atomic) when getting into multithreading. But use java.util.concurrent data structures whenever you can.

I received the exact same error message. Except that my error message said "Could not load file or assembly 'EntityFramework, Version=6.0.0.0...", because I installed EF 6.1.1. Here's what I did to resolve the problem.

1) I started NuGet Manager Console by clicking on Tools > NuGet Package Manager > Package Manager Console 2) I uninstalled the installed EntityFramework 6.1.1 by typing the following command:

Uninstall-package EntityFramework

3) Once I received confirmation that the package has been uninstalled successfully, I installed the 5.0.0 version by typing the following command:

Install-Package EntityFramework -version 5.0.0

The problem is resolved.

This is an extension method. See here for an explanation.

Extension methods allow developers to add new methods to the public contract of an existing CLR type, without having to sub-class it or recompile the original type. Extension Methods help blend the flexibility of "duck typing" support popular within dynamic languages today with the performance and compile-time validation of strongly-typed languages.

Extension Methods enable a variety of useful scenarios, and help make possible the really powerful LINQ query framework... .

it means that you can call

MyClass myClass = new MyClass();
int i = myClass.Foo();

rather than

MyClass myClass = new MyClass();
int i = Foo(myClass);

This allows the construction of fluent interfaces as stated below.

For new line characters

UPDATE table_name SET field_name = TRIM(TRAILING '\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r\n' FROM field_name);

For all white space characters

UPDATE table_name SET field_name = TRIM(field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\t' FROM field_name);

This helped me understand / streamline, only what I needed to animate:

// SCSS - Multiple Animation: Properties | durations | etc.
// on hover, animate div (width/opacity) - from: {0px, 0} to: {100vw, 1}

.base {
  max-width: 0vw;
  opacity: 0;

  transition-property: max-width, opacity; // relative order
  transition-duration: 2s, 4s; // effects relatively ordered animation properties
  transition-delay: 6s; // effects delay of all animation properties
  animation-timing-function: ease;

  &:hover {
    max-width: 100vw;
    opacity: 1;

    transition-duration: 5s; // effects duration of all aniomation properties
    transition-delay: 2s, 7s; // effects relatively ordered animation properties
  }
}

~ This applies for all transition properties (duration, transition-timing-function, etc.) within the '.base' class

The quintessential example of this is an array of pointers to structs or objects (that are mutable).

A shallow copy copies the array and maintains references to the original objects.

A deep copy will copy (clone) the objects too so they bear no relation to the original. Implicit in this is that the object themselves are deep copied. This is where it gets hard because there's no real way to know if something was deep copied or not.

The copy constructor is used to initilize the new object with the previously created object of the same class. By default compiler wrote a shallow copy. Shallow copy works fine when dynamic memory allocation is not involved because when dynamic memory allocation is involved then both objects will points towards the same memory location in a heap, Therefore to remove this problem we wrote deep copy so both objects have their own copy of attributes in a memory.

In order to read the details with complete examples and explanations you could see the article Constructors and destructors.

The default copy constructor is shallow. You can make your own copy constructors deep or shallow, as appropriate. See C++ Notes: OOP: Copy Constructors.

For people just stumbling upon this now, I resolved an error of this type that was thrown with all the references and using statements placed properly. There's evidently some confusion with substituting in a function that returns DataTable instead of calling it on a declared DataTable. For example:

This worked for me:

DataTable dt = SomeObject.ReturnsDataTable();

List<string> ls = dt.AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();

But this didn't:

List<string> ls = SomeObject.ReturnsDataTable().AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();

I'm still not 100% sure why, but if anyone is frustrated by an error of this type, give this a try.

As it is written in the documentation you have to change the cell type to a markdown.

I normally use on instead of click. It allow me to add more events listeners to a specific function.

$(document).on("click touchend", ".class1, .class2, .class3", function () {
     //do stuff
});

I think you're looking for;

  string[] skus = myLines.Select(x => x.Sku).ToArray();

However, if you're going to iterate over the sku's in subsequent code I recommend not using the ToArray() bit as it forces the queries execution prematurely and makes the applications performance worse. Instead you can just do;

  var skus = myLines.Select(x => x.Sku); // produce IEnumerable<string>

  foreach (string sku in skus) // forces execution of the query

check this..

        string[] strArray = { "ABC", "BCD", "CDE", "DEF", "EFG", "FGH", "GHI" };
        Array.IndexOf(strArray, "C"); // not found, returns -1
        Array.IndexOf(strArray, "CDE"); // found, returns index

It happened to me as Iam behind a firewall. The dependencies doesn't get downloaded sometimes when you are running in Eclipse IDE. Make sure you use mvn clean install -U to resolve the problem. You would see the dependencies download after this.

Spring Boot, v2.3.0.RELEASE

Recommended (In application.properties):

logging.level.org.hibernate.SQL=DEBUG //logs all SQL DML statements
logging.level.org.hibernate.type=TRACE //logs all JDBC parameters 

parameters

Note:
The above will not give you a pretty-print though.
You can add it as a configuration:

properties.put("hibernate.format_sql", "true");

or as per below.

Works but NOT recommended

spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

Reason: It's better to let the logging framework manage/optimize the output for you + it doesn't give you the prepared statement parameters.

Or you can exploit the fact that Collections.sort() (or Arrays.sort()) is stable (it doesn't reorder elements that are equal) and use a Comparator to sort by age first and then another one to sort by name.

In this specific case this isn't a very good idea but if you have to be able to change the sort order in runtime, it might be useful.

Simple solution, just one line..

var obj = {
    "set1": [1, 2, 3],
    "set2": [4, 5, 6, 7, 8],
    "set3": [9, 10, 11, 12]
};

obj = Object.values(obj);

obj[1]....

Swift 4 Update

I also tried many options still i wasn't able to get my UIButton round cornered. I added the corner radius code inside the viewDidLayoutSubviews() Solved My issue.

func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        anyButton.layer.cornerRadius = anyButton.frame.height / 2
    }

Also we can adjust the cornerRadius as follows

func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        anyButton.layer.cornerRadius = 10 //Any suitable number as you prefer can be applied 
    }

I really like working with Eclipse and Java though (new to Java), because it throws errors in the editor if you are missing an EH handler. That makes things a LOT harder to forget to handle an exception...

Plus, with the IDE tools, it adds the try / catch block or another catch block automatically.

For Xcode 10.2:

Although this question has many answers but I wanted to explain the whole concept in detail so that everyone can apply this knowledge to further or previous versions of Xcode too.

Every Xcode project consists of one or more targets. According to apple, A target specifies a product to build and contains the instructions for building the product from a set of files in a project or workspace. So every target is a product (app) on its own.

Steps to change the name:

Step 1: Go to the Targets and open the Info tab of the target whose name you want to change.

Step 2: View the Bundle name key under the Custom iOS Target Properties that is set to the default property of $(PRODUCT_NAME).

Step 3: You can either change the Bundle name directly (not recommended) or if you open the Build Settings tab then on searching for Product Name under Setting you will see that Product Name is set to $(TARGET_NAME).

Step 3A: You can change the Product Name or you can also change the Target Name by double clicking on the target.

So changing the Product Name (App Name) or Target Name both will result into similar results. But if you only want to change the App Name and want to keep using the same Target Name then only change the Product Name.

You can use nested query for pagination as follow:

Paging from 4 Row to 8 Row where CustomerId is primary key.

SELECT Top 5 * FROM Customers
WHERE Country='Germany' AND CustomerId Not in (SELECT Top 3 CustomerID FROM Customers
WHERE Country='Germany' order by city) 
order by city;

Another thing to try is to re-install ca-certificates as detailed here.

# yum reinstall ca-certificates
...
# update-ca-trust force-enable 
# update-ca-trust extract

And another thing to try is to explicitly allow the one site's certificate in question as described here (especially if the one site is your own server and you already have the .pem in reach).

# cp /your/site.pem /etc/pki/ca-trust/source/anchors/
# update-ca-trust extract

I was running into this exact SO error after upgrading to PHP 5.6 on CentOS 6 trying to access the server itself which has a cheapsslsecurity certificate which maybe it needed to be updated, but instead I installed a letsencrypt certificate and with these two steps above it did the trick. I don't know why the second step was necessary.

If it is a web application deleting files in Temporary ASP.NET Files folder could be a solution.

Simple like that:

If you did some commits on top of master and just want to "backwards merge" master there (i.e. you want master to point to HEAD), the one-liner would be:

git checkout -B master HEAD

1. That creates a new branch named master, even if it exists already (which is like moving master and that's what we want).
2. The newly created branch is set to point to HEAD, which is where you are.
3. The new branch is checked out, so you are on master afterwards.

I found this especially useful in the case of sub-repositories, which also happen to be in a detached state rather often.

Nowadays, you should use ERB::Util.url_encode or CGI.escape. The primary difference between them is their handling of spaces:

>> ERB::Util.url_encode("foo/bar? baz&")
=> "foo%2Fbar%3F%20baz%26"

>> CGI.escape("foo/bar? baz&")
=> "foo%2Fbar%3F+baz%26"

CGI.escape follows the CGI/HTML forms spec and gives you an application/x-www-form-urlencoded string, which requires spaces be escaped to +, whereas ERB::Util.url_encode follows RFC 3986, which requires them to be encoded as %20.

See "What's the difference between URI.escape and CGI.escape?" for more discussion.

If you have a BASH shell on your mac/linux in-front of you, you try out the below steps to understand the redirection practically :

Create a 2 line script called zz.sh

#!/bin/bash
echo "Hello. This is a proper command"
junk_errorcommand

• The echo command's output goes into STDOUT filestream (file descriptor 1).
• The error command's output goes into STDERR filestream (file descriptor 2)

Currently, simply executing the script sends both STDOUT and STDERR to the screen.

./zz.sh

Now start with the standard redirection :

zz.sh > zfile.txt

In the above, "echo" (STDOUT) goes into the zfile.txt. Whereas "error" (STDERR) is displayed on the screen.

The above is the same as :

zz.sh 1> zfile.txt

Now you can try the opposite, and redirect "error" STDERR into the file. The STDOUT from "echo" command goes to the screen.

zz.sh 2> zfile.txt

Combining the above two, you get:

zz.sh 1> zfile.txt 2>&1

Explanation:

• FIRST, send STDOUT 1 to zfile.txt
• THEN, send STDERR 2 to STDOUT 1 itself (by using &1 pointer).
• Therefore, both 1 and 2 goes into the same file (zfile.txt)

Eventually, you can pack the whole thing inside nohup command & to run it in the background:

nohup zz.sh 1> zfile.txt 2>&1&

I definitely wouldn't use Block1. It doesn't seem right having the Error block in an IF statement unrelated to Errors.

Blocks 2,3 & 4 I guess are variations of a theme. I prefer the use of Blocks 3 & 4 over 2 only because of a dislike of the GOTO statement; I generally use the Block4 method.

The answer to this question depends on which platform you are using.
But irrespective of platform, you can reliably assume the following types:

 [8-bit] signed char: -127 to 127
 [8-bit] unsigned char: 0 to 255
 [16-bit]signed short: -32767 to 32767
 [16-bit]unsigned short: 0 to 65535
 [32-bit]signed long: -2147483647 to 2147483647
 [32-bit]unsigned long: 0 to 4294967295
 [64-bit]signed long long: -9223372036854775807 to 9223372036854775807
 [64-bit]unsigned long long: 0 to 18446744073709551615

I have a more general answer; but I believe it is useful for counting the columns for all tables in a DB:

SELECT table_name, count(*)
FROM information_schema.columns
GROUP BY table_name;

I encountered this issue because I used setState instead of state in the constructor.

EXAMPLE

Change the following incorrect code

constructor(props) {
  super(props);
  this.setState({
    key: ''
  });
}

to

constructor(props) {
  super(props);
  this.state = {
    key: ''
  }; 
}

If it has to be really fast you can include a list of primes:
http://www.bigprimes.net/archive/prime/

If you just have to know if a certain number is a prime number, there are various prime tests listed on wikipedia. They are probably the fastest method to determine if large numbers are primes, especially because they can tell you if a number is not a prime.

^{Assuming you actually mean timestamp because there is no datetime in Postgres}

Cast the timestamp column to a date, that will remove the time part:

select *
from the_table
where the_timestamp_column::date = date '2015-07-15';

This will return all rows from July, 15th.

Note that the above will not use an index on the_timestamp_column. If performance is critical, you need to either create an index on that expression or use a range condition:

select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
  and the_timestamp_column < timestamp '2015-07-16 00:00:00';

I faced this exception for a long time and was not able to pinpoint the problem. The exception says line 1 column 9. The mistake I did is to get the first line of the file which flume is processing.

Apache flume process the content of the file in patches. So, when flume throws this exception and says line 1, it means the first line in the current patch.

If your flume agent is configured to use batch size = 100, and (for example) the file contains 400 lines, this means the exception is thrown in one of the following lines 1, 101, 201,301.

How to discover the line which causes the problem?

You have three ways to do that.

1- pull the source code and run the agent in debug mode. If you are an average developer like me and do not know how to make this, check the other two options.

2- Try to split the file based on the batch size and run the flume agent again. If you split the file into 4 files, and the invalid json exists between lines 301 and 400, the flume agent will process the first 3 files and stop at the fourth file. Take the fourth file and again split it into more smaller files. continue the process until you reach a file with only one line and flume fails while processing it.

3- Reduce the batch size of the flume agent to only one and compare the number of processed events in the output of the sink you are using. For example, in my case I am using Solr sink. The file contains 400 lines. The flume agent is configured with batch size=100. When I run the flume agent, it fails at some point and throw that exception. At this point check how many documents are ingested in Solr. If the invalid json exists at line 346, the number of documents indexed into Solr will be 345, so the next line is the line which causes the problem.

In my case I followed the third option and fortunately I pinpoint the line which causes the problem.

This is a long answer but it actually does not solve the exception. How I overcome this exception?

I have no idea why Jackson library complain while parsing a json string contains escaped characters \n \r \t. I think (but I am not sure) the Jackson parser is by default escaping these characters which cases the json string to be split into two lines (in case of \n) and then it deals each line as a separate json string.

In my case we used a customized interceptor to remove these characters before being processed by the flume agent. This is the way we solved this problem.

When you deploy a Java EE web application (using frameworks or not),its structure must follow some requirements/specifications. These specifications come from :

• The servlet container (e.g Tomcat)
• Java Servlet API
• Your application domain

1. The Servlet container requirements
   If you use Apache Tomcat, the root directory of your application must be placed in the webapp folder. That may be different if you use another servlet container or application server.
   
   

2. Java Servlet API requirements
   Java Servlet API states that your root application directory must have the following structure :

   ApplicationName
   |
   |--META-INF
   |--WEB-INF
         |_web.xml       <-- Here is the configuration file of your web app(where you define servlets, filters, listeners...)
         |_classes       <--Here goes all the classes of your webapp, following the package structure you defined. Only 
         |_lib           <--Here goes all the libraries (jars) your application need
   

These requirements are defined by Java Servlet API.

3. Your application domain
Now that you've followed the requirements of the Servlet container(or application server) and the Java Servlet API requirements, you can organize the other parts of your webapp based upon what you need.
- You can put your resources (JSP files, plain text files, script files) in your application root directory. But then, people can access them directly from their browser, instead of their requests being processed by some logic provided by your application. So, to prevent your resources being directly accessed like that, you can put them in the WEB-INF directory, whose contents is only accessible by the server.
-If you use some frameworks, they often use configuration files. Most of these frameworks (struts, spring, hibernate) require you to put their configuration files in the classpath (the "classes" directory).

ROUTER LINK DIRECTIVE:

[routerLink]="link"                  //when u pass URL value from COMPONENT file
[routerLink]="['link','parameter']" //when you want to pass some parameters along with route

 routerLink="link"                  //when you directly pass some URL 
[routerLink]="['link']"              //when you directly pass some URL

You can use the function toprettyxml() from xml.dom.minidom in order to do that:

def prettify(elem):
    """Return a pretty-printed XML string for the Element.
    """
    rough_string = ElementTree.tostring(elem, 'utf-8')
    reparsed = minidom.parseString(rough_string)
    return reparsed.toprettyxml(indent="\t")

The idea is to print your Element in a string, parse it using minidom and convert it again in XML using the toprettyxml function.

Your question "what are they" is already answered above.

As far as debugging (your second question) though, and in developing libraries where you want to check for special input values, you may find the following functions useful in Windows C++:

_isnan(), _isfinite(), and _fpclass()

On Linux/Unix you should find isnan(), isfinite(), isnormal(), isinf(), fpclassify() useful (and you may need to link with libm by using the compiler flag -lm).

based on OP's answer to question:

Here's the general idea:

Get child items in the .NET Framework directory that are containers whose names match the pattern v number dot number. Sort them by descending name, take the first object, and return its name property.

Here's the script:

(Get-ChildItem -Path $Env:windir\Microsoft.NET\Framework | Where-Object {$_.PSIsContainer -eq $true } | Where-Object {$_.Name -match 'v\d\.\d'} | Sort-Object -Property Name -Descending | Select-Object -First 1).Name

=COUNTIF(A:A;"lisa")

You can replace the criteria with cell references from Column B

If you use any(lst) you see that lst is the iterable, which is a list of some items. If it contained [0, False, '', 0.0, [], {}, None] (which all have boolean values of False) then any(lst) would be False. If lst also contained any of the following [-1, True, "X", 0.00001] (all of which evaluate to True) then any(lst) would be True.

In the code you posted, x > 0 for x in lst, this is a different kind of iterable, called a generator expression. Before generator expressions were added to Python, you would have created a list comprehension, which looks very similar, but with surrounding []'s: [x > 0 for x in lst]. From the lst containing [-1, -2, 10, -4, 20], you would get this comprehended list: [False, False, True, False, True]. This internal value would then get passed to the any function, which would return True, since there is at least one True value.

But with generator expressions, Python no longer has to create that internal list of True(s) and False(s), the values will be generated as the any function iterates through the values generated one at a time by the generator expression. And, since any short-circuits, it will stop iterating as soon as it sees the first True value. This would be especially handy if you created lst using something like lst = range(-1,int(1e9)) (or xrange if you are using Python2.x). Even though this expression will generate over a billion entries, any only has to go as far as the third entry when it gets to 1, which evaluates True for x>0, and so any can return True.

If you had created a list comprehension, Python would first have had to create the billion-element list in memory, and then pass that to any. But by using a generator expression, you can have Python's builtin functions like any and all break out early, as soon as a True or False value is seen.

After several months, the best answer I have is my simple tool. It is raw but functional.

What I want is something similar to this. The JSON data can provide a skeleton for the JSON schema. I have not implemented it yet, but it should be possible to give an existing JSON schema as basis, so that the existing JSON schema plus JSON data can generate an updated JSON schema. If no such schema is given as input, completely default values are taken.

This would be very useful in iterative development: the first time the tool is run, the JSON schema is dummy, but it can be refined automatically according to the evolution of the data.

Because default parameters are resolved at compile time, not runtime. So the default values does not belong to the object being called, but to the reference type that it is being called through.

def p1( ):
    print("in p1")

def p2():
    print("in p2")

myDict={
    "P1": p1,
    "P2": p2

}

name=input("enter P1 or P2")

myDictname

To check for events on an element:

var events = $._data(element, "events")

Note that this will only work with direct event handlers, if you are using $(document).on("event-name", "jq-selector", function() { //logic }), you will want to see the getEvents function at the bottom of this answer

For example:

 var events = $._data(document.getElementById("myElemId"), "events")

or

 var events = $._data($("#myElemId")[0], "events")

Full Example:

<html>
    <head>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script>
        <script>
            $(function() {
                $("#textDiv").click(function() {
                    //Event Handling
                });
                var events = $._data(document.getElementById('textDiv'), "events");
                var hasEvents = (events != null);
            });
        </script>
    </head>
    <body>
        <div id="textDiv">Text</div>
    </body>
</html>

A more complete way to check, that includes dynamic listeners, installed with $(document).on

function getEvents(element) {
    var elemEvents = $._data(element, "events");
    var allDocEvnts = $._data(document, "events");
    for(var evntType in allDocEvnts) {
        if(allDocEvnts.hasOwnProperty(evntType)) {
            var evts = allDocEvnts[evntType];
            for(var i = 0; i < evts.length; i++) {
                if($(element).is(evts[i].selector)) {
                    if(elemEvents == null) {
                        elemEvents = {};
                    }
                    if(!elemEvents.hasOwnProperty(evntType)) {
                        elemEvents[evntType] = [];
                    }
                    elemEvents[evntType].push(evts[i]);
                }
            }
        }
    }
    return elemEvents;
}

Example usage:

getEvents($('#myElemId')[0])

By default, React escapes the HTML to prevent XSS (Cross-site scripting). If you really want to render HTML, you can use the dangerouslySetInnerHTML property:

<td dangerouslySetInnerHTML={{__html: this.state.actions}} />

React forces this intentionally-cumbersome syntax so that you don't accidentally render text as HTML and introduce XSS bugs.

You can use PdfBox from Apache which is simple to use and has good performance.

Here is an example of extracting text from a PDF file (you can read more here) :

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\Invoice.pdf");  // The PDF file from where you would like to extract
         File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
         PDFTextStripper stripper = new PDFTextStripper();
         wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
         stripper.writeText(pd, wr);
         if (pd != null) {
             pd.close();
         }
        // I use close() to flush the stream.
        wr.close();
 } catch (Exception e){
         e.printStackTrace();
        } 
     }
}

UPDATE:

You can get the text using PDFTextStripper:

PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created

For the same issues, I have removed the following line,

  File file = new File("c:\\file.xml");
  InputStream inputStream= new FileInputStream(file);
  Reader reader = new InputStreamReader(inputStream,"UTF-8");
  InputSource is = new InputSource(reader);
  is.setEncoding("UTF-8");

It is working fine. Not so sure why that UTF-8 gives problem. To keep me in shock, it works fine for UTF-8 also.

Am using Windows-7 32 bit and Netbeans IDE with Java *jdk1.6.0_13*. No idea how it works.

I haven't done anything with rank, but I discovered this today with row_number().

select item, name, sold, row_number() over(partition by item order by sold) as row from table_name

This will result in some repeating row numbers since in my case each name holds all items. Each item will be ordered by how many were sold.

+--------+------+-----+----+
|glasses |store1|  30 | 1  |
|glasses |store2|  35 | 2  |
|glasses |store3|  40 | 3  |
|shoes   |store2|  10 | 1  |
|shoes   |store1|  20 | 2  |
|shoes   |store3|  22 | 3  |
+--------+------+-----+----+

You can Do this

var array = [];

// assigning values to corresponding keys
array[0] = "Main page";
array[1] = "Guide page";
array[2] = "Articles page";
array[3] = "Forum board";


array.forEach(value => {
    console.log(value)
})

Most of the methods are obsolete since June, 1/2016 api changes

Below worked for me,

• access instagram on your browser say chrome, safari or firefox.
• Launch developer tools, go to console option.

• on command prompt enter below command and hit enter:

  window._sharedData.entry_data.ProfilePage[0].user.id
  

If you are lucky, you will get at first attempt, if not, be patient, refresh the page and try again. keep doing until you see user-id. Good luck!!

You can use chr() and ord() to convert betweeen letters and int numbers.

Here is a simple example.

>>> chr(97)
'a'
>>> ord('a')
97

I use <span style="display: inline-block; width: 2ch;">&#9;</span> for a two characters wide tab.

As mentioned in all other answers, the keyword continue will skip to the end of the current iteration.

Additionally you can label your loop starts and then use continue [labelname]; or break [labelname]; to control what's going on in nested loops:

loop1: for (int i = 1; i < 10; i++) {
    loop2: for (int j = 1; j < 10; j++) {
        if (i + j == 10)
            continue loop1;

        System.out.print(j);
    }
    System.out.println();
}

I found out a way to do this using functions.

Say, for example, you have 3 choices: A, B, and C. A and Bexecute a command, but C gives you more info and takes you to the original prompt again. This can be done using functions.

Note that since the line containg function demoFunction is just setting up the function, you need to call demoFunction after that script so the function will actually run.

You can easily adapt this by writing multiple other functions and calling them if you need to "GOTO" another place in your shell script.

function demoFunction {
        read -n1 -p "Pick a letter to run a command [A, B, or C for more info] " runCommand

        case $runCommand in
            a|A) printf "\n\tpwd being executed...\n" && pwd;;
            b|B) printf "\n\tls being executed...\n" && ls;;
            c|C) printf "\n\toption A runs pwd, option B runs ls\n" && demoFunction;;
        esac
}

demoFunction

I don't think you can attach down into a window that you are instancing... I KNOW you can't do it if the url's are on different domains (XSS and all that jazz), but you can talk UP from that window and access elements of the parent window assuming they are on the same domain. your best bet is to attach the stylesheet at the page you are loading, and if that page isn't on the same domain, (e.g. trying to restyle some one else's page,) you won't be able to.

You have to check which version of Excel you are targeting?

If you are targeting Excel 2010 use version 14 (as per Grant's screenshot answer), Excel 2007 use version 12 . You can not support Excel 2003 using vS2012 as they do not have the correct Interop dll installed.

The input won't have a value if it doesn't exist. Try this...

if($('.input1').val())

I'm new to python too. Here is something that looks like will do what you want to

axes([0.08, 0.08, 0.94-0.08, 0.94-0.08]) #[left, bottom, width, height]
axis('scaled')`

I believe this decides the size of the canvas.

The code says everything:

max@serv$ chmod 777 .

Okay, it doesn't say everything.

In UNIX and Linux, the ability to remove a file is not determined by the access bits of that file. It is determined by the access bits of the directory which contains the file.

Think of it this way -- deleting a file doesn't modify that file. You aren't writing to the file, so why should "w" on the file matter? Deleting a file requires editing the directory that points to the file, so you need "w" on the that directory.

Just to extend previous answers - it could help someone. If your getArguments() returns null, put it to onCreate() method and not to constructor of your fragment:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    int index = getArguments().getInt("index");
}

Less code is better code.

[NSThread sleepForTimeInterval:0.06];

Swift:

Thread.sleep(forTimeInterval: 0.06)

you need to take out the quotes:

soda = a + b

(You want to refer to the variables a and b, not the strings "a" and "b")

Hi all Please try this property

$( "p span" ).last().addClass( "highlight" );

Thanks

Maybe you can try,this method:

import tensorflow as tf
W1 = tf.Variable(tf.random_uniform([1], -1.0, 1.0))
init = tf.global_variables_initializer()
sess = tf.Session()
sess.run(init)
array = W1.eval(sess)
print (array)

using System.Linq;

string s = string.Join(";", myDict.Select(x => x.Key + "=" + x.Value).ToArray());

(And if you're using .NET 4, or newer, then you can omit the final ToArray call.)

Currently it only works for the .dropdown-menu:

.dropdown-menu .divider {
  height: 1px;
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

If you want it for other use, in your own css, following the bootstrap.css create another one:

.divider {
  height: 1px;
  width:100%;
  display:block; /* for use on default inline elements like span */
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

Okay, so I had the same issue as the asker, and tried both top answers. But only getting formula errors. Turned out that I needed to exchange the "," to ";" for the formulas to work. I am using XL 2007.

Example:

=LOOKUP(2;1/(A:A<>"");A:A)

or

=INDEX(A:A;MAX((A:A<>"")*(ROW(A:A))))

I typically have a secrets.py that is stored separately from my other python scripts and is not under version control. Then whenever required, you can do from secrets import <required_pwd_var>. This way you can rely on the operating systems in-built file security system without re-inventing your own.

Using Base64 encoding/decoding is also another way to obfuscate the password though not completely secure

In my navigation based app I do this:

myViewController.navigationItem.title = @"MyTitle";

This solved my problem : Sample alter table statement to change the ownership.

ALTER TABLE databasechangelog OWNER TO arwin_ash;
ALTER TABLE databasechangeloglock OWNER TO arwin_ash;

If the other answers fail, importing it as

import moment from 'moment/moment.js'

may work.

CSS Grid layout

Like tables, grid layout enables an author to align elements into columns and rows.
https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout

To change the column sizes, take a look at the grid-template-columns property.

dl {_x000D_
  display: grid;_x000D_
  grid-template-columns: max-content auto;_x000D_
}_x000D_
_x000D_
dt {_x000D_
  grid-column-start: 1;_x000D_
}_x000D_
_x000D_
dd {_x000D_
  grid-column-start: 2;_x000D_
}

<dl>_x000D_
  <dt>Mercury</dt>_x000D_
  <dd>Mercury (0.4 AU from the Sun) is the closest planet to the Sun and the smallest planet.</dd>_x000D_
  <dt>Venus</dt>_x000D_
  <dd>Venus (0.7 AU) is close in size to Earth, (0.815 Earth masses) and like Earth, has a thick silicate mantle around an iron core.</dd>_x000D_
  <dt>Earth</dt>_x000D_
  <dd>Earth (1 AU) is the largest and densest of the inner planets, the only one known to have current geological activity.</dd>_x000D_
</dl>

Use QString::arg() for the same effect.

Just Follow This

UIImageView *imgview = [[UIImageView alloc]initWithFrame:CGRectMake(10, 10, 300, 400)];
[imgview setImage:[UIImage imageNamed:@"YourImageName"]];
[imgview setContentMode:UIViewContentModeScaleAspectFit];
[self.view addSubview:imgview];

Set IFS to newline, like this:

IFS='
'
for x in `ls -l $1`; do echo $x; done

Put a sub-shell around it if you don't want to set IFS permanently:

(IFS='
'
for x in `ls -l $1`; do echo $x; done)

Or use while | read instead:

ls -l $1 | while read x; do echo $x; done

One more option, which runs the while/read at the same shell level:

while read x; do echo $x; done << EOF
$(ls -l $1)
EOF

If working on EJB client library:

You need to mention the argument for getting the initial context.

InitialContext ctx = new InitialContext();

If you do not, it will look in the project folder for properties file. Also you can include the properties credentials or values in your class file itself as follows:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");

InitialContext ctx = new InitialContext(props);

URL_PKG_PREFIXES: Constant that holds the name of the environment property for specifying the list of package prefixes to use when loading in URL context factories.

The EJB client library is the primary library to invoke remote EJB components.
This library can be used through the InitialContext. To invoke EJB components the library creates an EJB client context via a URL context factory. The only necessary configuration is to parse the value org.jboss.ejb.client.naming for the java.naming.factory.url.pkgs property to instantiate an InitialContext.

You can use Element.scrollIntoView() method as was mentioned above. If you leave it with no parameters inside you will have an instant ugly scroll. To prevent that you can add this parameter - behavior:"smooth".

Example:

document.getElementById('scroll-here-plz').scrollIntoView({behavior: "smooth", block: "start", inline: "nearest"});

Just replace scroll-here-plz with your div or element on a website. And if you see your element at the bottom of your window or the position is not what you would have expected, play with parameter block: "". You can use block: "start", block: "end" or block: "center".

Remember: Always use parameters inside an object {}.

If you would still have problems, go to https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView

There is detailed documentation for this method.

Just use window.open():

window.open('Prosjektplan.pdf')

Anyway, what guys are saying on comments is true. You better use <a target="_blank"> instead of click events.

You'll need to switch to the database you want the user on (not the admin db) ...

use mydatabase
