Programs & Examples On #Winhttp

The best way around this is (and many other situations) in my experience, is to use cntlm which is a local no-authentication proxy which points to a remote authentication proxy. You can then just set WinHTTP to point to your local CNTLM (usually localhost:3128), and you can set CNTLM itself to point to the remote authentication proxy. CNTLM has a "magic NTLM dialect detection" option which generates password hashes to be put into the CNTLM configuration files.

Complementing the answers this is a guide to find the private key of the certificate and add the permissions.

This is the guide to get FindPrivateKey.exe found in the guide for find the private key of the certificate.

I would exploit the retransmission behaviour of TCP.

1. Make the TCP component create a large receive window.
2. Receive some amount of packets without sending an ACK for them.
   • Process those in passes creating some (prefix) compressed data structure
   • Send duplicate ack for last packet that is not needed anymore/wait for retransmission timeout
   • Goto 2
3. All packets were accepted

This assumes some kind of benefit of buckets or multiple passes.

Probably by sorting the batches/buckets and merging them. -> radix trees

Use this technique to accept and sort the first 80% then read the last 20%, verify that the last 20% do not contain numbers that would land in the first 20% of the lowest numbers. Then send the 20% lowest numbers, remove from memory, accept the remaining 20% of new numbers and merge.**

I solved in a very simple way:

1. Set the value from props:

  const wrapper: ShallowWrapper = shallow(<ProfileViewClass name: 'Sample Name' />);

2. Html code:

  <input type='text' defaultValue={props.name} className='edituser-name' />

3. Access the attribute from wrapper.find(element).props().attribute-name:

  it('should render user name', () => {
    expect(wrapper.find('.edituser-name').props().defaultValue).toContain(props.name);
  });

Cheers

'<option value=''.$key.'">'

should be

'<option value="'.$key.'">'

You need the Microsoft.AspNet.WebApi.Core package.

You can see it in the .csproj file:

<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.0.0\lib\net45\System.Web.Http.dll</HintPath>
</Reference>

adding log4j-1.2.12.jar file has resolved the issue for me

You can do that in the client side only, in browser that accept Data URIs:

data:application/csv;charset=utf-8,content_encoded_as_url

In your example the Data URI must be:

data:application/csv;charset=utf-8,Col1%2CCol2%2CCol3%0AVal1%2CVal2%2CVal3%0AVal11%2CVal22%2CVal33%0AVal111%2CVal222%2CVal333

You can call this URI by:

• using window.open
• or setting the window.location
• or by the href of an anchor
• by adding the download attribute it will work in chrome, still have to test in IE.

To test, simply copy the URIs above and paste in your browser address bar. Or test the anchor below in a HTML page:

<a download="somedata.csv" href="data:application/csv;charset=utf-8,Col1%2CCol2%2CCol3%0AVal1%2CVal2%2CVal3%0AVal11%2CVal22%2CVal33%0AVal111%2CVal222%2CVal333">Example</a>

To create the content, getting the values from the table, you can use table2CSV and do:

var data = $table.table2CSV({delivery:'value'});

$('<a></a>')
    .attr('id','downloadFile')
    .attr('href','data:text/csv;charset=utf8,' + encodeURIComponent(data))
    .attr('download','filename.csv')
    .appendTo('body');

$('#downloadFile').ready(function() {
    $('#downloadFile').get(0).click();
});

Most, if not all, versions of IE don't support navigation to a data link, so a hack must be implemented, often with an iframe. Using an iFrame combined with document.execCommand('SaveAs'..), you can get similar behavior on most currently used versions of IE.

I tried this and it worked:

Object obj = 10;
String str = obj.toString(); 
double d = Double.valueOf(str).doubleValue();

for whole row

insert into xyz select * from xyz2 where id="1";

for selected column

insert into xyz(t_id,v_id,f_name) select t_id,v_id,f_name from xyz2 where id="1";

This answer is wrriten in Kotlin, but can easily be translated to Java.

If your arraylist's size is within a fixed small range, then this is a great solution.

var duplicateDetected = false
    if(arrList.size > 1){
        for(i in 0 until arrList.size){
            for(j in 0 until arrList.size){
                if(i != j && arrList.get(i) == arrList.get(j)){
                    duplicateDetected = true
                }
            }
        }
    }

Use is.na

DF <- data.frame(x = c(1, 2, 3), y = c(0, 10, NA), z=c(NA, 33, 22))
DF[!is.na(DF$y),]

You have to create two triggers, but you can move the common code into a procedure and have them both call the procedure.

Importing a .scss file that has a nested import with a different relative position won't work. the top proposed answer (using a lot of ../) is just a dirty hack that will work as long as you added enough ../ to reach the root of your project's deployment OS.

1. Add the target SCSS path as a search target for SCSS compiler. This can be achieved by adding the stylesheets folder into the scss config file, this is function of the framework you are using,

use :load_paths at config.rd for compass-based frameworks (Ex. rails)

use the following code at scss-config.json for fourseven/meteor-scss

{
  "includePaths": [
    "{}/node_modules/ionicons/dist/scss/"
  ]
}

2. Use absolute paths (vs. relative paths).

Example, with fourseven/meteor-scss, you can use {} to highlight top level of your project as per the following examplI

@import "{}/node_modules/module-name/stylesheet";

You don't need any plugins to do this. Just select all lines (Ctrl A) and then from the menu select Edit → Line → Reindent. This will work if your file is saved with an extension that contains HTML like .html or .php.

If you do this often, you may find this key mapping useful:

{ "keys": ["ctrl+shift+r"], "command": "reindent" , "args": { "single_line": false } }

If your file is not saved (e.g. you just pasted in a snippet to a new window), you can manually set the language for indentation by selecting the menu View → Syntax → language of choice before selecting the reindent option.

You should use the Time.IsZero() function instead:

func (Time) IsZero

func (t Time) IsZero() bool
IsZero reports whether t represents the zero time instant, January 1, year 1, 00:00:00 UTC.

All you need to do is pass the JspWriter object into your method as a parameter i.e.

void someOutput(JspWriter stream)

Then call it via:

<% someOutput(out) %>

The writer object is a local variable inside _jspService so you need to pass it into your utility method. The same would apply for all the other built in references (e.g. request, response, session).

A great way to see whats going on is to use Tomcat as your server and drill down into the 'work' directory for the '.java' file generated from your 'jsp' page. Alternatively in weblogic you can use the 'weblogic.jspc' page compiler to view the Java that will be generated when the page is requested.

Use WSDL.EXE utility to generate a Web Service proxy from WSDL.

You'll get a long C# source file that contains a class that looks like this:

/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Web.Services.WebServiceBindingAttribute(Name="MyService", Namespace="http://myservice.com/myservice")]
public partial class MyService : System.Web.Services.Protocols.SoapHttpClientProtocol {
    ...
}

In your client-side, Web-service-consuming code:

1. instantiate MyService.
2. set its Url property
3. invoke Web methods

If you are running Python 3.5, run the following terminal command:

sudo pip3 install -U nltk

Any other pip commands in terminal would be similar:

pip3 install --upgrade pip
sudo pip3 install -U numpy ::

Can I include GPL licensed code in a MIT licensed product?

You can. GPL is free software as well as MIT is, both licenses do not restrict you to bring together the code where as "include" is always two-way.

In copyright for a combined work (that is two or more works form together a work), it does not make much of a difference if the one work is "larger" than the other or not.

So if you include GPL licensed code in a MIT licensed product you will at the same time include a MIT licensed product in GPL licensed code as well.

As a second opinion, the OSI listed the following criteria (in more detail) for both licenses (MIT and GPL):

1. Free Redistribution
2. Source Code
3. Derived Works
4. Integrity of The Author's Source Code
5. No Discrimination Against Persons or Groups
6. No Discrimination Against Fields of Endeavor
7. Distribution of License
8. License Must Not Be Specific to a Product
9. License Must Not Restrict Other Software
10. License Must Be Technology-Neutral

Both allow the creation of combined works, which is what you've been asking for.

If combining the two works is considered being a derivate, then this is not restricted as well by both licenses.

And both licenses do not restrict to distribute the software.

It seems to me that the chief difference between the MIT license and GPL is that the MIT doesn't require modifications be open sourced whereas the GPL does.

The GPL doesn't require you to release your modifications only because you made them. That's not precise.

You might mix this with distribiution of software under GPL which is not what you've asked about directly.

Is that correct - is the GPL is more restrictive than the MIT license?

This is how I understand it:

As far as distribution counts, you need to put the whole package under GPL. MIT code inside of the package will still be available under MIT whereas the GPL applies to the package as a whole if not limited by higher rights.

"Restrictive" or "more restrictive" / "less restrictive" depends a lot on the point of view. For a software-user the MIT might result in software that is more restricted than the one available under GPL even some call the GPL more restrictive nowadays. That user in specific will call the MIT more restrictive. It's just subjective to say so and different people will give you different answers to that.

As it's just subjective to talk about restrictions of different licenses, you should think about what you would like to achieve instead:

• If you want to restrict the use of your modifications, then MIT is able to be more restrictive than the GPL for distribution and that might be what you're looking for.
• In case you want to ensure that the freedom of your software does not get restricted that much by the users you distribute it to, then you might want to release under GPL instead of MIT.

As long as you're the author it's you who can decide.

So the most restrictive person ever is the author, regardless of which license anybody is opting for ;)

@Gadde - your answer was very helpful. Thank you! I needed a "Maps"-like zoom for a div and was able to produce the feel I needed with your post. My criteria included the need to have the click repeat and continue to zoom out/in with each click. Below is my final result.

    var currentZoom = 1.0;

    $(document).ready(function () {
        $('#btn_ZoomIn').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom += .1 }, 'slow');
            })
        $('#btn_ZoomOut').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom -= .1 }, 'slow');
            })
        $('#btn_ZoomReset').click(
            function () {
                currentZoom = 1.0
                $('#divName').animate({ 'zoom': 1 }, 'slow');
            })
    });

I had to do the opposite, and make html links into just the URL, but I modified your regex and it works like a charm, thanks :)

var exp = /<a\s.*href=['"](\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])['"].*>.*<\/a>/ig;

source = source.replace(exp,"$1");

From the docs:

The comparison uses lexicographical ordering: first the first two items are compared, and if they differ this determines the outcome of the comparison; if they are equal, the next two items are compared, and so on, until either sequence is exhausted.

Also:

Lexicographical ordering for strings uses the Unicode code point number to order individual characters.

or on Python 2:

Lexicographical ordering for strings uses the ASCII ordering for individual characters.

As an example:

>>> 'abc' > 'bac'
False
>>> ord('a'), ord('b')
(97, 98)

The result False is returned as soon as a is found to be less than b. The further items are not compared (as you can see for the second items: b > a is True).

Be aware of lower and uppercase:

>>> [(x, ord(x)) for x in abc]
[('a', 97), ('b', 98), ('c', 99), ('d', 100), ('e', 101), ('f', 102), ('g', 103), ('h', 104), ('i', 105), ('j', 106), ('k', 107), ('l', 108), ('m', 109), ('n', 110), ('o', 111), ('p', 112), ('q', 113), ('r', 114), ('s', 115), ('t', 116), ('u', 117), ('v', 118), ('w', 119), ('x', 120), ('y', 121), ('z', 122)]
>>> [(x, ord(x)) for x in abc.upper()]
[('A', 65), ('B', 66), ('C', 67), ('D', 68), ('E', 69), ('F', 70), ('G', 71), ('H', 72), ('I', 73), ('J', 74), ('K', 75), ('L', 76), ('M', 77), ('N', 78), ('O', 79), ('P', 80), ('Q', 81), ('R', 82), ('S', 83), ('T', 84), ('U', 85), ('V', 86), ('W', 87), ('X', 88), ('Y', 89), ('Z', 90)]

You can use Symbol

var say = Symbol()

function Cat(){
  this[say]() // call private methos
}

Cat.prototype[say] = function(){ alert('im a private') }

P.S. alexpods is not correct. he get protect rather than private, since inheritance is a name conflict

Actually you can use var say = String(Math.random()) instead Symbol

IN ES6:

var say = Symbol()

class Cat {

  constructor(){
    this[say]() // call private
  }

  [say](){
    alert('im private')
  }

}

Use the Date.prototype.setFullYear method to set the year to what you want it to be.

For example:

var aYearFromNow = new Date();
aYearFromNow.setFullYear(aYearFromNow.getFullYear() + 1);

There really isn't another way to work with dates in JavaScript if these methods aren't present in the environment you are working with.

On Windows 2008 R2 servers you have two means of viewing what files are open and closing those connections.

The other answers cover the 2 most common approaches, Xinclude and XML external entities. Microsoft has a really great writeup on why one should prefer Xinclude, as well as several example implementations. I've quoted the comparison below:

Per http://msdn.microsoft.com/en-us/library/aa302291.aspx

Why XInclude?

The first question one may ask is "Why use XInclude instead of XML external entities?" The answer is that XML external entities have a number of well-known limitations and inconvenient implications, which effectively prevent them from being a general-purpose inclusion facility. Specifically:

• An XML external entity cannot be a full-blown independent XML document—neither standalone XML declaration nor Doctype declaration is allowed. That effectively means an XML external entity itself cannot include other external entities.
• An XML external entity must be well formed XML (not so bad at first glance, but imagine you want to include sample C# code into your XML document).
• Failure to load an external entity is a fatal error; any recovery is strictly forbidden.
• Only the whole external entity may be included, there is no way to include only a portion of a document. -External entities must be declared in a DTD or an internal subset. This opens a Pandora's Box full of implications, such as the fact that the document element must be named in Doctype declaration and that validating readers may require that the full content model of the document be defined in DTD among others.

The deficiencies of using XML external entities as an inclusion mechanism have been known for some time and in fact spawned the submission of the XML Inclusion Proposal to the W3C in 1999 by Microsoft and IBM. The proposal defined a processing model and syntax for a general-purpose XML inclusion facility.

Four years later, version 1.0 of the XML Inclusions, also known as Xinclude, is a Candidate Recommendation, which means that the W3C believes that it has been widely reviewed and satisfies the basic technical problems it set out to solve, but is not yet a full recommendation.

Another good site which provides a variety of example implementations is https://www.xml.com/pub/a/2002/07/31/xinclude.html. Below is a common use case example from their site:

<book xmlns:xi="http://www.w3.org/2001/XInclude">

  <title>The Wit and Wisdom of George W. Bush</title>

  <xi:include href="malapropisms.xml"/>

  <xi:include href="mispronunciations.xml"/>

  <xi:include href="madeupwords.xml"/>

</book>

I know it is an old question but there's two type of environment variables. The one owned with User and the one system wide. Depending how do you open git bash (with user privilege or with administrator privilege) the environment variable PATH used can be from you User variables or from System variables. See below:

as said in a previous answer, check with the command env|grep PATH to see which one you are using and update your variable accordingly. BTW, no need to reboot the system. Just close and reopen the git bash

Store information:

static final String PLAYER_SCORE = "playerScore";
static final String PLAYER_LEVEL = "playerLevel";

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    // Save the user's current game state
    savedInstanceState.putInt(PLAYER_SCORE, mCurrentScore);
    savedInstanceState.putInt(PLAYER_LEVEL, mCurrentLevel);

// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
}

If you don't want to restore information in your onCreate-Method:

Here are the examples: Recreating an Activity

Instead of restoring the state during onCreate() you may choose to implement onRestoreInstanceState(), which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null

public void onRestoreInstanceState(Bundle savedInstanceState) {
// Always call the superclass so it can restore the view hierarchy
super.onRestoreInstanceState(savedInstanceState);

// Restore state members from saved instance
mCurrentScore = savedInstanceState.getInt(PLAYER_SCORE);
mCurrentLevel = savedInstanceState.getInt(PLAYER_LEVEL);
}

I had the same errors.

I added System.Data.Entity.Repository from Nuget Packages and the errors disappears.

Hope it wil help!

Your expression is never going to evaluate.

You are comparing a with a property of a.

a is of type Answer. a.Correct, I'm guessing is a boolean.

Long form:-

Answer = answer.SingleOrDefault(a => a.Correct == true);

Short form:-

Answer = answer.SingleOrDefault(a => a.Correct);

All of the answers above are correct; attr_reader and attr_writer are more convenient to write than manually typing the methods they are shorthands for. Apart from that they offer much better performance than writing the method definition yourself. For more info see slide 152 onwards from this talk (PDF) by Aaron Patterson.

Try this

function checkForm($fields){
        foreach($fields as $field){
            if($field['required'] && strlen($_POST[$field['name']]) <= 0){
                $field['value'] = "Some error";
            }
        }
        return $field;
    }

1. Use this: URLEncoder.encode(query, StandardCharsets.UTF_8.displayName()); or this:URLEncoder.encode(query, "UTF-8");

2. You can use the follwing code.

   String encodedUrl1 = UriUtils.encodeQuery(query, "UTF-8");//not change 
   String encodedUrl2 = URLEncoder.encode(query, "UTF-8");//changed
   String encodedUrl3 = URLEncoder.encode(query, StandardCharsets.UTF_8.displayName());//changed
   
   System.out.println("url1 " + encodedUrl1 + "\n" + "url2=" + encodedUrl2 + "\n" + "url3=" + encodedUrl3);
   

if you have Firebug installed on Firefox, just open the url. In the network panel, right-click and select Copy as cURL. You can see all curl parameters for this web call.

df.filter((df.bar != 'a') & (df.bar != 'b'))

I would use the SET command from the command prompt to export all the variables, rather than just PATH as recommended above.

C:\> SET >> allvariables.txt

To import the variablies, one can use a simple loop:

C:\> for /F %A in (allvariables.txt) do SET %A

You are using Lists, concrete ArrayList. ArrayList also implements Collection interface. Collection interface has sort method which is used to sort the elements present in the specified list of Collection in ascending order. This will be the quickest and possibly the best way for your case.

Sorting a list in ascending order can be performed as default operation on this way:

Collections.sort(list);

Sorting a list in descending order can be performed on this way:

Collections.reverse(list);

According to these facts, your solution has to be written like this:

public class tes 
{
    public static void main(String args[])
    {
        List<Integer> lList = new ArrayList<Integer>();
        lList.add(4);
        lList.add(1);
        lList.add(7);
        lList.add(2);
        lList.add(9);
        lList.add(1);
        lList.add(5);

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

More about Collections you can read here.

You should try using the Grid Template.

Here's what I've used for a two Column Layout of a <ul>

<ul class="list-group row">
     <li class="list-group-item col-xs-6">Row1</li>
     <li class="list-group-item col-xs-6">Row2</li>
     <li class="list-group-item col-xs-6">Row3</li>
     <li class="list-group-item col-xs-6">Row4</li>
     <li class="list-group-item col-xs-6">Row5</li>
</ul>

This worked for me.

With versions of cut I know of, no, this is not possible. cut is primarily useful for parsing files where the separator is not whitespace (for example /etc/passwd) and that have a fixed number of fields. Two separators in a row mean an empty field, and that goes for whitespace too.

A combination of previous 2 answers did the trick. Thanks. A new class which inherits from Button. Note: updateImages() should be called before showing the button.

import javafx.event.EventHandler;
import javafx.scene.control.Button;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.MouseEvent;

public class ImageButton extends Button {

    public void updateImages(final Image selected, final Image unselected) {
        final ImageView iv = new ImageView(selected);
        this.getChildren().add(iv);

        iv.setOnMousePressed(new EventHandler<MouseEvent>() {
            public void handle(MouseEvent evt) {
                iv.setImage(unselected);
            }
        });
        iv.setOnMouseReleased(new EventHandler<MouseEvent>() {
            public void handle(MouseEvent evt) {
                iv.setImage(selected);
            }
        });

        super.setGraphic(iv);
    }
}

The difference is the same as a (Hash)Map vs List.

JSONObject:

• Contains named values (key->value pairs, tuples or whatever you want to call them)
  • like {ID : 1}
• Order of elements is not important
  • a JSONObject of {id: 1, name: 'B'} is equal to {name: 'B', id: 1}.

JSONArray:

• Contains only series values
  • like [1, 'value']
• Order of values is important
  • array of [1,'value'] is not the same as ['value',1]

Example

JSON Object --> { "":""}

JSON Array --> [ , , , ]

{"employees":[
    {"firstName":"John", "lastName":"Doe"},
    {"firstName":"Anna", "lastName":"Smith"},
    {"firstName":"Peter", "lastName":"Jones"}
]}

a is an array local to the function.Once the function returns it does not exist anymore and hence you should not return the address of a local variable.
In other words the lifetime of a is within the scope({,}) of the function and if you return a pointer to it what you have is a pointer pointing to some memory which is not valid. Such variables are also called automatic variabels because their lifetime is automatically managed you do not need to manage it explicitly.

Since you need to extend the variable to persist beyond the scope of the function you You need to allocate a array on heap and return a pointer to it.

char *a = malloc(1000); 

This way the array a resides in memory untill you call a free() on the same address.
Do not forget to do so or you end up with a memory leak.

I had the same issue and tried almost everything then found after I came to know I was trying it in the wrong block. I was trying it in steps block whereas it needs to be in the environment block.

        stage('Release') {
                    environment {
                            my_var = sh(script: "/bin/bash ${assign_version} || ls ", , returnStdout: true).trim()
                                }
                    steps {                                 
                            println my_var
                            }
                }

public static String getStackTrace(Throwable t) {
    StringWriter sw = new StringWriter();
    t.printStackTrace(new PrintWriter(sw));
    return sw.toString();
}

I use this class:

public class JsonContent : StringContent
{
    public JsonContent(object obj) :
        base(JsonConvert.SerializeObject(obj), Encoding.UTF8, "application/json")
    { }
}

Sample of usage:

new HttpClient().PostAsync("http://...", new JsonContent(new { x = 1, y = 2 }));

Using Firebase's Query API, you might be tempted to try this:

// !!! THIS WILL NOT WORK !!!
ref
  .orderBy('genre')
  .startAt('comedy').endAt('comedy')
  .orderBy('lead')                  // !!! THIS LINE WILL RAISE AN ERROR !!!
  .startAt('Jack Nicholson').endAt('Jack Nicholson')
  .on('value', function(snapshot) { 
      console.log(snapshot.val()); 
  });

But as @RobDiMarco from Firebase says in the comments:

multiple orderBy() calls will throw an error

So my code above will not work.

I know of three approaches that will work.

1. filter most on the server, do the rest on the client

What you can do is execute one orderBy().startAt()./endAt() on the server, pull down the remaining data and filter that in JavaScript code on your client.

ref
  .orderBy('genre')
  .equalTo('comedy')
  .on('child_added', function(snapshot) { 
      var movie = snapshot.val();
      if (movie.lead == 'Jack Nicholson') {
          console.log(movie);
      }
  });

2. add a property that combines the values that you want to filter on

If that isn't good enough, you should consider modifying/expanding your data to allow your use-case. For example: you could stuff genre+lead into a single property that you just use for this filter.

"movie1": {
    "genre": "comedy",
    "name": "As good as it gets",
    "lead": "Jack Nicholson",
    "genre_lead": "comedy_Jack Nicholson"
}, //...

You're essentially building your own multi-column index that way and can query it with:

ref
  .orderBy('genre_lead')
  .equalTo('comedy_Jack Nicholson')
  .on('child_added', function(snapshot) { 
      var movie = snapshot.val();
      console.log(movie);
  });

David East has written a library called QueryBase that helps with generating such properties.

You could even do relative/range queries, let's say that you want to allow querying movies by category and year. You'd use this data structure:

"movie1": {
    "genre": "comedy",
    "name": "As good as it gets",
    "lead": "Jack Nicholson",
    "genre_year": "comedy_1997"
}, //...

And then query for comedies of the 90s with:

ref
  .orderBy('genre_year')
  .startAt('comedy_1990')
  .endAt('comedy_2000')
  .on('child_added', function(snapshot) { 
      var movie = snapshot.val();
      console.log(movie);
  });

If you need to filter on more than just the year, make sure to add the other date parts in descending order, e.g. "comedy_1997-12-25". This way the lexicographical ordering that Firebase does on string values will be the same as the chronological ordering.

This combining of values in a property can work with more than two values, but you can only do a range filter on the last value in the composite property.

A very special variant of this is implemented by the GeoFire library for Firebase. This library combines the latitude and longitude of a location into a so-called Geohash, which can then be used to do realtime range queries on Firebase.

3. create a custom index programmatically

Yet another alternative is to do what we've all done before this new Query API was added: create an index in a different node:

  "movies"
      // the same structure you have today
  "by_genre"
      "comedy"
          "by_lead"
              "Jack Nicholson"
                  "movie1"
              "Jim Carrey"
                  "movie3"
      "Horror"
          "by_lead"
              "Jack Nicholson"
                  "movie2"
      

There are probably more approaches. For example, this answer highlights an alternative tree-shaped custom index: https://stackoverflow.com/a/34105063

If none of these options work for you, but you still want to store your data in Firebase, you can also consider using its Cloud Firestore database.

Cloud Firestore can handle multiple equality filters in a single query, but only one range filter. Under the hood it essentially uses the same query model, but it's like it auto-generates the composite properties for you. See Firestore's documentation on compound queries.

I needed this for a dictionary instead of list, Jochen solution was the most elegant for that case so I modded it a bit:

class CaseInsensitiveDict(dict):
    ''' requests special dicts are case insensitive when using the in operator,
     this implements a similar behaviour'''
    def __contains__(self, name): # implements `in`
        return name.casefold() in (n.casefold() for n in self.keys())

now you can convert a dictionary like so USERNAMESDICT = CaseInsensitiveDict(USERNAMESDICT) and use if 'MICHAEL89' in USERNAMESDICT:

You need the sleep method of the Thread class.

public static void sleep (long time)

Causes the thread which sent this message to sleep for the given interval of time (given in milliseconds). The precision is not guaranteed - the Thread may sleep more or less than requested.

Parameters

time The time to sleep in milliseconds.

The best solution for this is to write a custom assignment_tag. This solution is more clean than using a with tag because it achieves a very clear separation between logic and styling.

Start by creating a template tag file (eg. appname/templatetags/hello_world.py):

from django import template

register = template.Library()

@register.assignment_tag
def get_addressee():
    return "World"

Now you may use the get_addressee template tag in your templates:

{% load hello_world %}

{% get_addressee as addressee %}

<html>
    <body>
        <h1>hello {{addressee}}</h1>
    </body>
</html>

Hera's the function UpdateWindowsList_WindowMenu() that you must call after any operations are performed on Tabs.Here windowToolStripMenuItem is the menu item added to Window Menu to menu strip.

public void UpdateWindowsList_WindowMenu()  
{  
    //get all tab pages from tabControl1  
    TabControl.TabPageCollection tabcoll = tabControl1.TabPages;  

    //get  windowToolStripMenuItem drop down menu items count  
    int n = windowToolStripMenuItem.DropDownItems.Count;  

    //remove all menu items from of windowToolStripMenuItem  
    for (int i = n - 1; i >=2; i--)  
    {  
        windowToolStripMenuItem.DropDownItems.RemoveAt(i);  
    }  

    //read each tabpage from tabcoll and add each tabpage text to windowToolStripMenuItem  
    foreach (TabPage tabpage in tabcoll)  
    {  
        //create Toolstripmenuitem  
        ToolStripMenuItem menuitem = new ToolStripMenuItem();  
        String s = tabpage.Text;  
        menuitem.Text = s;  

        if (tabControl1.SelectedTab == tabpage)  
        {  
            menuitem.Checked = true;  
        }  
        else  
        {  
            menuitem.Checked = false;  
        }  

        //add menuitem to windowToolStripMenuItem  
        windowToolStripMenuItem.DropDownItems.Add(menuitem);  

        //add click events to each added menuitem  
        menuitem.Click += new System.EventHandler(WindowListEvent_Click);  
    }  
}  

private void WindowListEvent_Click(object sender, EventArgs e)  
{  
    //casting ToolStripMenuItem to ToolStripItem  
    ToolStripItem toolstripitem = (ToolStripItem)sender;  

    //create collection of tabs of tabContro1  
    //check every tab text is equal to clicked menuitem then select the tab  
    TabControl.TabPageCollection tabcoll = tabControl1.TabPages;  
    foreach (TabPage tb in tabcoll)  
    {  
        if (toolstripitem.Text == tb.Text)  
        {  
            tabControl1.SelectedTab = tb;  
            //call UpdateWindowsList_WindowMenu() to perform changes on menuitems  
            UpdateWindowsList_WindowMenu();  
        }  
    }  
}  

Your transfer speed is likely not to be limited by Java. Instead I would suspect (in no particular order)

1. the speed of transfer from the database
2. the speed of transfer to the disk

If you read the complete dataset and then write it out to disk, then that will take longer, since the JVM will have to allocate memory, and the db rea/disk write will happen sequentially. Instead I would write out to the buffered writer for every read that you make from the db, and so the operation will be closer to a concurrent one (I don't know if you're doing that or not)

Take a look at my answer here.

Answer to comment:

The FFT actually calculates the cross-correlation of the input signal with sine and cosine functions (basis functions) at a range of equally spaced frequencies. For a given FFT output, there is a corresponding frequency (F) as given by the answer I posted. The real part of the output sample is the cross-correlation of the input signal with cos(2*pi*F*t) and the imaginary part is the cross-correlation of the input signal with sin(2*pi*F*t). The reason the input signal is correlated with sin and cos functions is to account for phase differences between the input signal and basis functions.

By taking the magnitude of the complex FFT output, you get a measure of how well the input signal correlates with sinusoids at a set of frequencies regardless of the input signal phase. If you are just analyzing frequency content of a signal, you will almost always take the magnitude or magnitude squared of the complex output of the FFT.

If you'd like to have your JAVA_HOME recognised by intellij, you can do one of these:

• Start your intellij from terminal /Applications/IntelliJ IDEA 14.app/Contents/MacOS (this will pick your bash env variables)
• Add login env variable by executing: launchctl setenv JAVA_HOME "/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home"

To directly answer your question, you can add launchctl line in your ~/.bash_profile

As others have answered you can ignore JAVA_HOME by setting up SDK in project structure.

Another solution is

class T1
{
    enum
    {
        t = 100
    };

    public:
    T1();
};

So t is initialised to 100 and it cannot be changed and it is private.

in your view blade change to

{{ Form::open(['action' => 'postcontroller@edit', 'method' => 'PUT', 'class' = 'your class here']) }}

<div>
{{ Form::textarea('textareanamehere', 'default value here', ['placeholder' => 'your place holder here', 'class' => 'your class here']) }}
</div>

<div>
{{ Form::submit('Update', ['class' => 'btn class here'])}}
</div>

{{ Form::close() }}

actually you can use raw form like your question. but i dont recomended it. dan itulah salah satu alasan agan belajar framework, simple, dan cepat. so kenapa pake raw form kalo ada yang lebih mudah. hehe. proud to be indonesian.

Just thinking about the original question... which, I think we can conclude from all the other learned answers, and also from Bloch's essential Effective Java, item 7, "Avoid finalizers", seeks the solution to a legitimate question in a manner which is inappropriate to the Java language...:

... wouldn't a pretty obvious solution to do what the OP actually wants be to keep all your objects which need to be reset in a sort of "playpen", to which all other non-resettable objects have references only through some sort of accessor object...

And then when you need to "reset" you disconnect the existing playpen and make a new one: all the web of objects in the playpen is cast adrift, never to return, and one day to be collected by the GC.

If any of these objects are Closeable (or not, but have a close method) you could put them in a Bag in the playpen as they are created (and possibly opened), and the last act of the accessor before cutting off the playpen would be to go through all the Closeables closing them... ?

The code would probably look something like this:

accessor.getPlaypen().closeCloseables();
accessor.setPlaypen( new Playpen() );

closeCloseables would probably be a blocking method, probably involving a latch (e.g. CountdownLatch), to deal with (and wait as appropriate for) any Runnables/Callables in any threads specific to the Playpen to be ended as appropriate, in particular in the JavaFX thread.

As the recent developed Web Applications are using JavaScript, jQuery, AngularJS, ReactJS etc there is a possibility that to retrieve an attribute of an element through Selenium you have to induce WebDriverWait to synchronize the WebDriver instance with the lagging Web Client i.e. the Web Browser before trying to retrieve any of the attributes.

Some examples:

• Python:

  • To retrieve any attribute form a visible element (e.g. <h1> tag) you need to use the expected_conditions as visibility_of_element_located(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "org"))).get_attribute("attribute_name")
    

  • To retrieve any attribute form an interactive element (e.g. <input> tag) you need to use the expected_conditions as element_to_be_clickable(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "org"))).get_attribute("attribute_name")
    

HTML Attributes

Below is a list of some attributes often used in HTML

Note: A complete list of all attributes for each HTML element, is listed in: HTML Attribute Reference

As an improvement on Peters code above you can use this:

   var roleManager = new RoleManager<Microsoft.AspNet.Identity.EntityFramework.IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));

   if (!roleManager.RoleExists("Member"))
            roleManager.Create(new IdentityRole("Member"));

Here is the simple, easy to read, recursive function that works very well:

function zip_r($from, $zip, $base=false) {
    if (!file_exists($from) OR !extension_loaded('zip')) {return false;}
    if (!$base) {$base = $from;}
    $base = trim($base, '/');
    $zip->addEmptyDir($base);
    $dir = opendir($from);
    while (false !== ($file = readdir($dir))) {
        if ($file == '.' OR $file == '..') {continue;}

        if (is_dir($from . '/' . $file)) {
            zip_r($from . '/' . $file, $zip, $base . '/' . $file);
        } else {
            $zip->addFile($from . '/' . $file, $base . '/' . $file);
        }
    }
    return $zip;
}
$from = "/path/to/folder";
$base = "basezipfolder";
$zip = new ZipArchive();
$zip->open('zipfile.zip', ZIPARCHIVE::CREATE);
$zip = zip_r($from, $zip, $base);
$zip->close();

Yes! In your settings.py define the following

LOGIN_REDIRECT_URL = '/your-path'

And have '/your-path' be a simple View that looks up self.request.user and does whatever logic it needs to return a HttpResponseRedirect object.

A better way might be to define a simple URL like '/simple' that does the lookup logic there. The URL looks more beautiful, saves you some work, etc.

I use:

body.modal-open .datepicker {
    z-index: 1200 !important;
}

This way: if the modal isn't open, and you want the datepicker to be at the normal z-index (in my case I needed it to be under the menu drop-down, which has a z-index of 1000), it works.

If the modal is open, the datepicker needs to be over the modal z-index (1040 or 1050), so use the body.modal-open selector.

When the servlet container (like Apache Tomcat) starts up, it will read from the web.xml file (only one per application) if anything goes wrong or shows up an error at container side console, otherwise, it will deploy and load all web applications by using web.xml (so named it as deployment descriptor).

During instantiation phase of the servlet, servlet instance is ready but it cannot serve the client request because it is missing with two pieces of information:
1: context information
2: initial configuration information

Servlet engine creates servletConfig interface object encapsulating the above missing information into it servlet engine calls init() of the servlet by supplying servletConfig object references as an argument. Once init() is completely executed servlet is ready to serve the client request.

Q) In the lifetime of servlet how many times instantiation and initialization happens ??

A)only once (for every client request a new thread is created) only one instance of the servlet serves any number of the client request ie, after serving one client request server does not die. It waits for other client requests ie what CGI (for every client request a new process is created) limitation is overcome with the servlet (internally servlet engine creates the thread).

Q)How session concept works?

A)whenever getSession() is called on HttpServletRequest object

Step 1: request object is evaluated for incoming session ID.

Step 2: if ID not available a brand new HttpSession object is created and its corresponding session ID is generated (ie of HashTable) session ID is stored into httpservlet response object and the reference of HttpSession object is returned to the servlet (doGet/doPost).

Step 3: if ID available brand new session object is not created session ID is picked up from the request object search is made in the collection of sessions by using session ID as the key.

Once the search is successful session ID is stored into HttpServletResponse and the existing session object references are returned to the doGet() or doPost() of UserDefineservlet.

Note:

1)when control leaves from servlet code to client don't forget that session object is being held by servlet container ie, the servlet engine

2)multithreading is left to servlet developers people for implementing ie., handle the multiple requests of client nothing to bother about multithread code

Inshort form:

A servlet is created when the application starts (it is deployed on the servlet container) or when it is first accessed (depending on the load-on-startup setting) when the servlet is instantiated, the init() method of the servlet is called then the servlet (its one and only instance) handles all requests (its service() method being called by multiple threads). That's why it is not advisable to have any synchronization in it, and you should avoid instance variables of the servlet when the application is undeployed (the servlet container stops), the destroy() method is called.

If you want to run docker as non-root user then you need to add it to the docker group.

1. Create the docker group if it does not exist

$ sudo groupadd docker

2. Add your user to the docker group.

$ sudo usermod -aG docker $USER

3. Run the following command or Logout and login again and run (that doesn't work you may need to reboot your machine first)

$ newgrp docker

4. Check if docker can be run without root

$ docker run hello-world

Reboot if still got error

$ reboot

Taken from the docker official documentation: manage-docker-as-a-non-root-user

For many purposes simply calling sorted will suffice. For example

>>> s = set([0, 1, 2, 99, 4, 40, 3, 20, 24, 100, 60])
>>> sorted(s)
[0, 1, 2, 3, 4, 20, 24, 40, 60, 99, 100]

If you are going to use this repeatedly, there will be overhead incurred by calling the sorted function so you might want to save the resulting list, as long as you're done changing the set. If you need to maintain unique elements and sorted, I agree with the suggestion of using OrderedDict from collections with an arbitrary value such as None.

Following JavaScript function handles ', ", \b, \t, \n, \f or \r equivalent of php function addslashes().

function addslashes(string) {
    return string.replace(/\\/g, '\\\\').
        replace(/\u0008/g, '\\b').
        replace(/\t/g, '\\t').
        replace(/\n/g, '\\n').
        replace(/\f/g, '\\f').
        replace(/\r/g, '\\r').
        replace(/'/g, '\\\'').
        replace(/"/g, '\\"');
}

Acording to your first code snipet seems ok, but I've got similar behavior caused by bad programing. Have you checked the "options" variable is not null before the put call?

I'm using Struts2 (2.3.3) webapp and use a HashMap for displaying results. When is executed (in a class initialized by an Action class) :

if(value != null) pdfMap.put("date",value.toString());

Got this error:

I guess problem is in width attributes in table and td remove 'px' for example

<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">

Should be

<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">

You can try this,

Step1: Override the Tabselected method in your activity

@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
    // When the given tab is selected, switch to the corresponding page in
    // the ViewPager.
    try {
    if(MyEventsFragment!=null && tab.getPosition()==3)
    {
        MyEvents.fragmentChanged();
    }
    }
    catch (Exception e)
    {

    }
    mViewPager.setCurrentItem(tab.getPosition());
}

Step 2: Using static method do what you want in your fragment,

public static void fragmentChanged()
{
    Toast.makeText(actvity, "Fragment Changed", Toast.LENGTH_SHORT).show();
}

On OSX (and Solaris, apparently), the mkfile command is available as well:

mkfile 10g big_file

This makes a 10 GB file named "big_file". Found this approach here.

This worked for me: Open task manager (of your OS) and kill adb.exe process. Now start adb again, now adb should start normally.

Well, you pretty much gave yourself the answer. In your CSS give the containing element a min-width. If you have to support IE6 you can use the min-width-trick:

#container {
    min-width:800px;
    width: auto !important;
    width:800px;
}

That will effectively give you 800px min-width in IE6 and any up-to-date browsers.

TL;DR:

Please refer to the glossary: hash() is used as a shortcut to comparing objects, an object is deemed hashable if it can be compared to other objects. that is why we use hash(). It's also used to access dict and set elements which are implemented as resizable hash tables in CPython.

Technical considerations

• usually comparing objects (which may involve several levels of recursion) is expensive.
• preferably, the hash() function is an order of magnitude (or several) less expensive.
• comparing two hashes is easier than comparing two objects, this is where the shortcut is.

If you read about how dictionaries are implemented, they use hash tables, which means deriving a key from an object is a corner stone for retrieving objects in dictionaries in O(1). That's however very dependent on your hash function to be collision-resistant. The worst case for getting an item in a dictionary is actually O(n).

On that note, mutable objects are usually not hashable. The hashable property means you can use an object as a key. If the hash value is used as a key and the contents of that same object change, then what should the hash function return? Is it the same key or a different one? It depends on how you define your hash function.

Learning by example:

Imagine we have this class:

>>> class Person(object):
...     def __init__(self, name, ssn, address):
...         self.name = name
...         self.ssn = ssn
...         self.address = address
...     def __hash__(self):
...         return hash(self.ssn)
...     def __eq__(self, other):
...         return self.ssn == other.ssn
... 

Please note: this is all based on the assumption that the SSN never changes for an individual (don't even know where to actually verify that fact from authoritative source).

And we have Bob:

>>> bob = Person('bob', '1111-222-333', None)

Bob goes to see a judge to change his name:

>>> jim = Person('jim bo', '1111-222-333', 'sf bay area')

This is what we know:

>>> bob == jim
True

But these are two different objects with different memory allocated, just like two different records of the same person:

>>> bob is jim
False

Now comes the part where hash() is handy:

>>> dmv_appointments = {}
>>> dmv_appointments[bob] = 'tomorrow'

Guess what:

>>> dmv_appointments[jim] #?
'tomorrow'

From two different records you are able to access the same information. Now try this:

>>> dmv_appointments[hash(jim)]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 9, in __eq__
AttributeError: 'int' object has no attribute 'ssn'
>>> hash(jim) == hash(hash(jim))
True

What just happened? That's a collision. Because hash(jim) == hash(hash(jim)) which are both integers btw, we need to compare the input of __getitem__ with all items that collide. The builtin int does not have an ssn attribute so it trips.

>>> del Person.__eq__
>>> dmv_appointments[bob]
'tomorrow'
>>> dmv_appointments[jim]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: <__main__.Person object at 0x7f611bd37110>

In this last example, I show that even with a collision, the comparison is performed, the objects are no longer equal, which means it successfully raises a KeyError.

In my case, I was defining a bean and autowiring it in the constructor of the same class file.

@SpringBootApplication
public class MyApplication {
    private MyBean myBean;

    public MyApplication(MyBean myBean) {
        this.myBean = myBean;
    }

    @Bean
    public MyBean myBean() {
        return new MyBean();
    }
}

My solution was to move the bean definition to another class file.

@Configuration
public CustomConfig {
    @Bean
    public MyBean myBean() {
        return new MyBean();
    }
}

If you want to avoid the mess of the case statement being in your query twice, you may want to place it in a User-Defined-Function.

Sorry, but SQL Server would not render the dataset before the Group By clause so the column alias is not available. You could use it in the Order By.

This is a textbook case for a constructor function:

var myArray = [];

function myElement(id, value){
    this.id = id
    this.value = value
}

myArray[0] = new myElement(0,1)
myArray[1] = new myElement(2,3)
// or myArray.push(new myElement(1, 1))

Here is my solution to see if I am using an argparse variable

import argparse

ap = argparse.ArgumentParser()
ap.add_argument("-1", "--first", required=True)
ap.add_argument("-2", "--second", required=True)
ap.add_argument("-3", "--third", required=False) 
# Combine all arguments into a list called args
args = vars(ap.parse_args())
if args["third"] is not None:
# do something

This might give more insight to the above answer which I used and adapted to work for my program.

Create a .reg file containing your proxy settings for your users. Create a batch file setting it to setting it to run the .reg file with the extension /s

On a server using a logon script, tell the logon to run the batch file. Jason

I found some detailed instructions here: http://digitallibraryworld.com/?p=6

The key piece of advice seems to be, don't use the 64-bit ASP.DLL (found in system32) if you've configured the app pool to run 32-bit applications (instead, use the 32-bit ASP.DLL).

Add a script map using the following setting:

Request Path: *.asp
Executable: C:\Windows\system32\inetsrv\asp.dll
Name: whatever you want. I named my Classic ASP

The executable above is 64 BIT ASP handler for your asp script. If you want your ASP script to be handled in 32 bit environment, you need to use executable from this location: C:\Windows\SysWOW64\inetsrv\asp.dll.

Of course, if you don't need to load any 32-bit libraries (or data providers, etc.), just make your life easier by running the 64-bit ASP.DLL!

Objective C includes a built-in way to detect a the encoding of a string embedded in NSData.

NSData* data = // Assign your NSData object...

NSString* string;
NSStringEncoding encoding = [NSString stringEncodingForData:data encodingOptions:nil convertedString:&string usedLossyConversion:nil];

I have a case where I am transforming a legacy DB2 z/os database timestamp (formatted as: "yyyy-MM-dd'T'HH:mm:ss.SSSZ") into a SqlServer 2016 datetime2 (formatted as: "yyyy-MM-dd HH:mm:ss.SSS) field that is handled by our Spring/Hibernate Entity Manager instance (in this case, the OldRevision Table). In the Class, I define the date as the java.util type, and write the setter and getter in the normal way. Then, When handling the data, the code I have handling the data related to this question looks like this:

OldRevision revision = new OldRevision();
String oldRevisionDateString= oldRevisionData.getString("originalRevisionDate", "");
Date oldDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
oldDateFormat.parse(oldRevisionDateString);
SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
newDateFormat.setTimeZone(TimeZone.getTimeZone("EST"));
Date finalFormattedDate= newDateFormat.parse(newDateFormat.format(oldDateFormat));
revision.setOriginalRevisionDate(finalFormattedDate);
em.persist(revision);

A simpler way to do the same case is:

SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
newDateFormat.setTimeZone(TimeZone.getTimeZone("EST"));
revision.setOriginalRevisionDate(
        newDateFormat.parse(newDateFormat.format(
                new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ")
                        .parse(rs.getString("originalRevisionDate", "")))));

Sometimes it may be better to use chrome.storage API. It's better then localStorage because you can:

• store information from your content script without the need for message passing between content script and extension;
• store your data as JavaScript objects without serializing them to JSON (localStorage only stores strings).

Here's a simple code demonstrating the use of chrome.storage. Content script gets the url of visited page and timestamp and stores it, popup.js gets it from storage area.

content_script.js

(function () {
    var visited = window.location.href;
    var time = +new Date();
    chrome.storage.sync.set({'visitedPages':{pageUrl:visited,time:time}}, function () {
        console.log("Just visited",visited)
    });
})();

popup.js

(function () {
    chrome.storage.onChanged.addListener(function (changes,areaName) {
        console.log("New item in storage",changes.visitedPages.newValue);
    })
})();

"Changes" here is an object that contains old and new value for a given key. "AreaName" argument refers to name of storage area, either 'local', 'sync' or 'managed'.

Remember to declare storage permission in manifest.json.

manifest.json

...
"permissions": [
    "storage"
 ],
...

I got it working with this code.

using iTextSharp.text;
using iTextSharp.text.pdf;

public FileStreamResult pdf()
{
    MemoryStream workStream = new MemoryStream();
    Document document = new Document();
    PdfWriter.GetInstance(document, workStream).CloseStream = false;

    document.Open();
    document.Add(new Paragraph("Hello World"));
    document.Add(new Paragraph(DateTime.Now.ToString()));
    document.Close();

    byte[] byteInfo = workStream.ToArray();
    workStream.Write(byteInfo, 0, byteInfo.Length);
    workStream.Position = 0;

    return new FileStreamResult(workStream, "application/pdf");    
}

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

Follow the steps given here

http://www.javaandme.com/

after setting variable, just navigate to your java file directory in your cmd and type javac "xyx.java"

or if you don't navigate to the directory, then simply specify the full path of java file

javac "/xyz.java"

Try this to reload jqGrid with new data

jQuery("#grid").jqGrid('setGridParam',{datatype:'json'}).trigger('reloadGrid');

Because str in python2 is bytes actually. So if want to write unicode to csv, you must encode unicode to str using utf-8 encoding.

def py2_unicode_to_str(u):
    # unicode is only exist in python2
    assert isinstance(u, unicode)
    return u.encode('utf-8')

Use class csv.DictWriter(csvfile, fieldnames, restval='', extrasaction='raise', dialect='excel', *args, **kwds):

• py2
  • The csvfile: open(fp, 'w')
  • pass key and value in bytes which are encoded with utf-8
    • writer.writerow({py2_unicode_to_str(k): py2_unicode_to_str(v) for k,v in row.items()})
• py3
  • The csvfile: open(fp, 'w')
  • pass normal dict contains str as row to writer.writerow(row)

Finally code

import sys

is_py2 = sys.version_info[0] == 2

def py2_unicode_to_str(u):
    # unicode is only exist in python2
    assert isinstance(u, unicode)
    return u.encode('utf-8')

with open('file.csv', 'w') as f:
    if is_py2:
        data = {u'Python??': u'Python??', u'Python??2': u'Python??2'}

        # just one more line to handle this
        data = {py2_unicode_to_str(k): py2_unicode_to_str(v) for k, v in data.items()}

        fields = list(data[0])
        writer = csv.DictWriter(f, fieldnames=fields)

        for row in data:
            writer.writerow(row)
    else:
        data = {'Python??': 'Python??', 'Python??2': 'Python??2'}

        fields = list(data[0])
        writer = csv.DictWriter(f, fieldnames=fields)

        for row in data:
            writer.writerow(row)

Conclusion

In python3, just use the unicode str.

In python2, use unicode handle text, use str when I/O occurs.

Even though it's too late, I'd like to give my input on this as it might clarify why the solution given by JB Nizet works. I stumbled upon this little problem working on a byte parser and to string conversion myself. When you copy from a bigger size integral type to a smaller size integral type as this java doc says this happens:

https://docs.oracle.com/javase/specs/jls/se7/html/jls-5.html#jls-5.1.3 A narrowing conversion of a signed integer to an integral type T simply discards all but the n lowest order bits, where n is the number of bits used to represent type T. In addition to a possible loss of information about the magnitude of the numeric value, this may cause the sign of the resulting value to differ from the sign of the input value.

You can be sure that a byte is an integral type as this java doc says https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html byte: The byte data type is an 8-bit signed two's complement integer.

So in the case of casting an integer(32 bits) to a byte(8 bits), you just copy the last (least significant 8 bits) of that integer to the given byte variable.

int a = 128;
byte b = (byte)a; // Last 8 bits gets copied
System.out.println(b);  // -128

Second part of the story involves how Java unary and binary operators promote operands. https://docs.oracle.com/javase/specs/jls/se7/html/jls-5.html#jls-5.6.2 Widening primitive conversion (§5.1.2) is applied to convert either or both operands as specified by the following rules:

If either operand is of type double, the other is converted to double.

Otherwise, if either operand is of type float, the other is converted to float.

Otherwise, if either operand is of type long, the other is converted to long.

Otherwise, both operands are converted to type int.

Rest assured, if you are working with integral type int and/or lower it'll be promoted to an int.

// byte b(0x80) gets promoted to int (0xFF80) by the & operator and then
// 0xFF80 & 0xFF (0xFF translates to 0x00FF) bitwise operation yields 
// 0x0080
a = b & 0xFF;
System.out.println(a); // 128

I scratched my head around this too :). There is a good answer for this here by rgettman. Bitwise operators in java only for integer and long?

You can use simple trick which is import flask app variable from main inside another file, like:

test-routes.py

from __main__ import app

@app.route('/test', methods=['GET'])
def test():
    return 'it works!'

and in your main files, where you declared flask app, import test-routes, like:

app.py

from flask import Flask, request, abort

app = Flask(__name__)

# import declared routes
import test-routes

It works from my side.

I faced a problem upgrading pip from version 9.0.1 to 9.0.3 The upgrade failed middle way(after uninstalling version 9.0.1 and without installing version 9.0.3). This usually creates a broken pip file. Broken pip can be solved by the command-->

easy_install pip

Which usually installs the latest version of pip, and solves the issue. In order to confirm, type

pip --version

Hope this was helpfull...

The conceptual difference in my understanding it that a project can contain many repo's and that are independent of each other, while simultaneously a repo may contain many projects. Repo's being just a storage place for code while a project being a collection of tasks for a certain feature.

Does that make sense? A large repo can have many projects being worked on by different people at the same time (lots of difference features being added to a monolith), a large project may have many small repos that are separate but part of the same project that interact with each other - microservices? Its a personal take on what you want to do. I think that repo (storage) vs project (tasks) is the main difference - if i am wrong please let me know / explain! Thanks.

[EDIT] The expected output of the pluck function has changed from Laravel 5.1 to 5.2. Hence why it is marked as deprecated in 5.1

In Laravel 5.1, pluck gets a single column's value from the first result of a query.

In Laravel 5.2, pluck gets an array with the values of a given column. So it's no longer deprecated, but it no longer do what it used to.

So short answer is use the value function if you want one column from the first row and you are using Laravel 5.1 or above.

Thanks to Tomas Buteler for pointing this out in the comments.

[ORIGINAL] For anyone coming across this question who is using Laravel 5.1, pluck() has been deprecated and will be removed completely in Laravel 5.2.

Consider future proofing your code by using value() instead.

return DB::table('users')->where('username', $username)->value('groupName');

Swift 4 Code

Step 1 In ViewdidLoad()

   let pictureTap = UITapGestureRecognizer(target: self, action: #selector(MyInfoTableViewController.imageTapped))
       userImageView.addGestureRecognizer(pictureTap)
       userImageView.isUserInteractionEnabled = true

Step 2 Add Following Function

@objc func imageTapped() {

        let imageView = userImageView
        let newImageView = UIImageView(image: imageView?.image)
        newImageView.frame = UIScreen.main.bounds
        newImageView.backgroundColor = UIColor.black
        newImageView.contentMode = .scaleAspectFit
        newImageView.isUserInteractionEnabled = true
        let tap = UITapGestureRecognizer(target: self, action: #selector(dismissFullscreenImage))
        newImageView.addGestureRecognizer(tap)
        self.view.addSubview(newImageView)

        self.navigationController?.isNavigationBarHidden = true
        self.tabBarController?.tabBar.isHidden = true

    }

It's Tested And Working Properly

You can set date as environment variable and later u can use it

setenv DATE `date "+%Y-%m-%d"`
echo "----------- ${DATE} -------------"

or

DATE =`date "+%Y-%m-%d"`
echo "----------- ${DATE} -------------"

I was hitting this issue while running Tomcat inside of a Docker container. To fix this make sure you add the '-p 8000:8000' argument in your docker run command to expose this port to your local machine. You will of course need the setenv.sh file in your ${CATALINA_HOME}/bin/ within your container as well.

Try below code:

Resources resources = context.getResources();
int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
if (resourceId > 0) {
    return resources.getDimensionPixelSize(resourceId);
}
return 0;

Solved, just renamed the Global.asax or delete it fixed the problem :/

Other known related bugs I found on the web:

1. Global.asax.cs: must inherit from HttpApplication -> public class MvcApplication : HttpApplication
2. Project output must be the bin folder and not Bin/Debug, etc.
3. Iss application pool is not in the correct .net version.

The answer really depends on how familiar you are with batch, if you are not so experienced, I would recommend incrementing a loop variable:

@echo off
set /a loop=1
:repeat
echo Hello World!
set /a loop=%loop%+1
if %loop%==<no. of times to repeat> (
goto escapedfromrepeat
)
goto repeat
:escapedfromrepeat
echo You have come out of the loop
pause

But if you are more experienced with batch, I would recommend the more practical for /l %loop in (1, 1, 10) do echo %loop is the better choice.

             (start at 1, go up in 1's, end at 10)
for /l %[your choice] (start, step, end) do [command of your choice]

For just reading file and outputting it the best one would be readfile.

In C, you cannot reference the typedef that you're creating withing the structure itself. You have to use the structure name, as in the following test program:

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

typedef struct Cell {
  int cellSeq;
  struct Cell* next; /* 'tCell *next' will not work here */
} tCell;

int main(void) {
    int i;
    tCell *curr;
    tCell *first;
    tCell *last;

    /* Construct linked list, 100 down to 80. */

    first = malloc (sizeof (tCell));
    last = first;
    first->cellSeq = 100;
    first->next = NULL;
    for (i = 0; i < 20; i++) {
        curr = malloc (sizeof (tCell));
        curr->cellSeq = last->cellSeq - 1;
        curr->next = NULL;
        last->next = curr;
        last = curr;
    }

    /* Walk the list, printing sequence numbers. */

    curr = first;
    while (curr != NULL) {
        printf ("Sequence = %d\n", curr->cellSeq);
        curr = curr->next;
    }

    return 0;
}

Although it's probably a lot more complicated than this in the standard, you can think of it as the compiler knowing about struct Cell on the first line of the typedef but not knowing about tCell until the last line :-) That's how I remember that rule.

if(empty(array_intersect([21,22,23,24], $check_with_this)) {
 print "Not found even a single element";
} else {
 print "Found an element";
}

array_intersect() returns an array containing all the values of array1 that are present in all the arguments. Note that keys are preserved.

Returns an array containing all of the values in array1 whose values exist in all of the parameters.

empty() — Determine whether a variable is empty

Returns FALSE if var exists and has a non-empty, non-zero value. Otherwise returns TRUE.

Try stream-series. It works like merge-stream/event-stream.merge() except that instead of interleaving, it appends to the end. It doesn't require you to specify the object mode like streamqueue, so your code comes out cleaner.

var series = require('stream-series');

gulp.task('minifyInOrder', function() {
    return series(gulp.src('vendor/*'),gulp.src('extra'),gulp.src('house/*'))
        .pipe(concat('a.js'))
        .pipe(uglify())
        .pipe(gulp.dest('dest'))
});

Here is what I did

private void myEvent_Handler(object sender, SomeEvent e)
{
  // I dont know how many times this event will fire
  Task t = new Task(() =>
  {
    if (something == true) 
    {
        DoSomething(e);  
    }
  });
  t.RunSynchronously();
}

working great and not blocking UI thread

If you want some space at left and right of input view, you can add some padding like

private fun showAlertWithTextInputLayout(context: Context) {
    val textInputLayout = TextInputLayout(context)
    textInputLayout.setPadding(
        resources.getDimensionPixelOffset(R.dimen.dp_19), // if you look at android alert_dialog.xml, you will see the message textview have margin 14dp and padding 5dp. This is the reason why I use 19 here
        0,
        resources.getDimensionPixelOffset(R.dimen.dp_19),
        0
    )
    val input = EditText(context)
    textInputLayout.hint = "Email"
    textInputLayout.addView(input)

    val alert = AlertDialog.Builder(context)
        .setTitle("Reset Password")
        .setView(textInputLayout)
        .setMessage("Please enter your email address")
        .setPositiveButton("Submit") { dialog, _ ->
            // do some thing with input.text
            dialog.cancel()
        }
        .setNegativeButton("Cancel") { dialog, _ ->
            dialog.cancel()
        }.create()

    alert.show()
}

dimens.xml

<dimen name="dp_19">19dp</dimen>

Hope it help

Well, since the date of this question post, a Python library addressed this topic. pynput library, from Moses Palmer, is GREAT to catch keyboard and mouse events in a very simple way.

• GitHub repository is here: https://github.com/moses-palmer/pynput
• PyPi project is there: enter link description here
• and installation of lib is easy: 'pip install pynput'

(mind the missing 'i' in pynput - I missed it too... ;-) )

You can use either "=" or "==" operators for string comparison in bash. The important factor is the spacing within the brackets. The proper method is for brackets to contain spacing within, and operators to contain spacing around. In some instances different combinations work; however, the following is intended to be a universal example.

if [ "$1" == "something" ]; then     ## GOOD

if [ "$1" = "something" ]; then      ## GOOD

if [ "$1"="something" ]; then        ## BAD (operator spacing)

if ["$1" == "something"]; then       ## BAD (bracket spacing)

Also, note double brackets are handled slightly differently compared to single brackets ...

if [[ $a == z* ]]; then   # True if $a starts with a "z" (pattern matching).
if [[ $a == "z*" ]]; then # True if $a is equal to z* (literal matching).

if [ $a == z* ]; then     # File globbing and word splitting take place.
if [ "$a" == "z*" ]; then # True if $a is equal to z* (literal matching).

I hope that helps!

Use Range in Python 3.

Here is a example function that return in between numbers from two numbers

def get_between_numbers(a, b):
    """
    This function will return in between numbers from two numbers.
    :param a:
    :param b:
    :return:
    """
    x = []
    if b < a:
        x.extend(range(b, a))
        x.append(a)
    else:
        x.extend(range(a, b))
        x.append(b)

    return x

Result

print(get_between_numbers(5, 9))
print(get_between_numbers(9, 5))

[5, 6, 7, 8, 9]  
[5, 6, 7, 8, 9]

If you are using jQuery, you don't have to do anything special. Handlers added via $(document).ready() don't overwrite each other, but rather execute in turn:

$(document).ready(func1)
...
$(document).ready(func2)

If you are not using jQuery, you could use addEventListener, as demonstrated by Karaxuna, plus attachEvent for IE<9.

Note that onload is not equivalent to $(document).ready() - the former waits for CSS, images... as well, while the latter waits for the DOM tree only. Modern browsers (and IE since IE9) support the DOMContentLoaded event on the document, which corresponds to the jQuery ready event, but IE<9 does not.

if(window.addEventListener){
  window.addEventListener('load', func1)
}else{
  window.attachEvent('onload', func1)
}
...
if(window.addEventListener){
  window.addEventListener('load', func2)
}else{
  window.attachEvent('onload', func2)
}

If neither option is available (for example, you are not dealing with DOM nodes), you can still do this (I am using onload as an example, but other options are available for onload):

var oldOnload1=window.onload;
window.onload=function(){
  oldOnload1 && oldOnload1();
  func1();
}
...
var oldOnload2=window.onload;
window.onload=function(){
  oldOnload2 && oldOnload2();
  func2();
}

or, to avoid polluting the global namespace (and likely encountering namespace collisions), using the import/export IIFE pattern:

window.onload=(function(oldLoad){
  return function(){
    oldLoad && oldLoad();
    func1();
  }
})(window.onload)
...
window.onload=(function(oldLoad){
  return function(){
    oldLoad && oldLoad();
    func2();
  }
})(window.onload)

Try this

$('.slidingDiv').toggle("slide", {direction: "right" }, 1000);

Remove specific index(i removed 16 and 21 from matrix)

import numpy as np
mat = np.arange(12,26)
a = [4,9]
del_map = np.delete(mat, a)
del_map.reshape(3,4)

Output:

array([[12, 13, 14, 15],
      [17, 18, 19, 20],
      [22, 23, 24, 25]])

$ sudo apt-get install libpq-dev

Year, this solve my problem. After execute this, do: pip install psycopg2

According to wikipedia, the most browser-compatible incantation is:

<link rel="shortcut icon" href="favicon.ico" />

After that, you just need to worry about whether your browser is actually downloading the icon. What do the server logs say? Have you checked your browsers network debugging console?

You could manually set the cookie, but depending on your use case (and if you might want to add more types of persistent/session data in future) it might make more sense to use Django's sessions feature. This will let you get and set variables tied internally to the user's session cookie. Cool thing about this is that if you want to store a lot of data tied to a user's session, storing it all in cookies will add a lot of weight to HTTP requests and responses. With sessions the session cookie is all that is sent back and forth (though there is the overhead on Django's end of storing the session data to keep in mind).

I excluded the root ("/") mount point by using grep -vw "^/".

# cat /tmp/topfsfind.txt| head -4 |awk '{print $NF}'
/
/root/.m2
/root
/var

# cat /tmp/topfsfind.txt| head -4 |awk '{print $NF}' | grep -vw "^/"
/root/.m2
/root
/var

I've had this problem too. I found the answer here: http://www.dynamicdrive.com/forums/showthread.php?t=63628

This is an example of the solution that works on firefox, you need to add this line to your font face css:

src: local(font name), url("font_name.ttf");

parseDouble() method is used to initialise a STRING (which should contains some numerical value)....the value it returns is of primitive data type, like int, float, etc.

But valueOf() creates an object of Wrapper class. You have to unwrap it in order to get the double value. It can be compared with a chocolate. The manufacturer wraps the chocolate with some foil or paper to prevent from pollution. The user takes the chocolate, removes and throws the wrapper and eats it.

Observe the following conversion.

int k = 100; Integer it1 = new Integer(k);

The int data type k is converted into an object, it1 using Integer class. The it1 object can be used in Java programming wherever k is required an object.

The following code can be used to unwrap (getting back int from Integer object) the object it1.

int m = it1.intValue();

System.out.println(m*m); // prints 10000

//intValue() is a method of Integer class that returns an int data type.

Okay I'm guessing you are on Windows using Visual Studio... why? Well because if you are on some sort of Linux OS then you'd probably be running it from the console.

Anyways, you can add crap to the end of your program like others are suggesting, or you can just hit CTRL + F5 (start without debugging) and Visual Studio will leave the console up once complete.

Another option if you want to run the Debug version and not add crap to your code is to open the console window (Start -> Run -> cmd) and navigate to your Debug output directory. Then, just enter the name of your executable and it will run your debug program in the console. You can then use Visual Studio's attach to process or something if you really want to.

I think _naked might get what you want, but it also prevents the compiler from generating the stack management code for the function. extern "C" causes C style name decoration. Remove that and that should get rid of your _'s. The linker doesn't add the underscores, the compiler does. stdcall causes the argument stack size to be appended.

For more, see: http://en.wikipedia.org/wiki/X86_calling_conventions http://www.codeproject.com/KB/cpp/calling_conventions_demystified.aspx

The bigger question is why do you want to do that? What's wrong with the mangled names?

Okay, redis is pretty user friendly but there are some gotchas.

Here are just some easy commands for working with redis on Ubuntu:

install:

sudo apt-get install redis-server

start with conf:

sudo redis-server <path to conf>
sudo redis-server config/redis.conf

stop with conf:

redis-ctl shutdown

(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)

log:

tail -f /var/log/redis/redis-server.log

Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:

/etc/redis/redis.conf

Then paste it at <path to conf>, tweak as needed and you're good to go.

The short version of the page linked by D Shu (and without the horrible popover ads) is that this "waiting for device" problem happens when the USB device node is not accessible to your current user. The USB id is different in fastboot mode, so you can easily have permission to it in adb but not in fastboot.

To fix it (on Ubuntu; other systems may be slightly different):

Run lsusb -v | less and find the relevant section which will look something like this:

Bus 001 Device 027: ID 18d1:4e30 Google Inc. 
Couldn't open device, some information will be missing
Device Descriptor:
...
  idVendor           0x18d1 Google Inc.

Now do

sudo vi /etc/udev/rules.d/11-android.rules

it's ok if that file does not yet exist; create it with a line like this, inserting your own username and vendor id:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", MODE="0640", OWNER="mbp"

then

sudo service udev restart

then verify the device node permissions have changed:

ls -Rl /dev/bus/usb

The even shorter cheesy version is to just run fastboot as root. But then you need to run every command that talks to the device as root, which tends to cause other complications. Simpler just to fix the permissions in the long run.

My favorite two ways to grab the contents of URLs are either OpenURI or Typhoeus.

OpenURI because it's everywhere, and Typhoeus because it's very flexible and powerful.

Prior Swift 3.0 :

String(data: yourData, encoding: NSUTF8StringEncoding)

For Swift 4.0:

String(data: yourData, encoding: .utf8)

The EntityManager.flush() operation can be used the write all changes to the database before the transaction is committed. By default JPA does not normally write changes to the database until the transaction is committed. This is normally desirable as it avoids database access, resources and locks until required. It also allows database writes to be ordered, and batched for optimal database access, and to maintain integrity constraints and avoid deadlocks. This means that when you call persist, merge, or remove the database DML INSERT, UPDATE, DELETE is not executed, until commit, or until a flush is triggered.

In my case, I got this while overloading

ostream & operator << (ostream &out, const MyClass &obj)

and forgot to return out. In other systems this just generates a warning, but on macos it also generated an error (although it seems to print correctly).

The error was resolved by adding the correct return value. In my case, adding the -mmacosx-version-min flag had no effect.

For <a> tags:

You need to stick target="_self" on your <a> tag

There are three cases where AngularJS will perform a full page reload:

• Links that contain target element
  Example: <a href="/ext/link?a=b" target="_self">link</a>
• Absolute links that go to a different domain
  Example: <a href="http://angularjs.org/">link</a>
• Links starting with '/' that lead to a different base path when base is defined
  Example: <a href="/not-my-base/link">link</a>

Using javascript:

The $location service allows you to change only the URL; it does not allow you to reload the page. When you need to change the URL and reload the page or navigate to a different page, please use a lower level API: $window.location.href.

See:

• https://docs.angularjs.org/guide/$location
• https://docs.angularjs.org/api/ng/service/$location

Well, you can do

DataTable data = (DataTable)(dgvMyMembers.DataSource);

and then use

data.Columns.Remove(...);

I think it's the fastest way. This will modify data source table, if you don't want it, then copy of table is reqired. Also be aware that DataGridView.DataSource is not necessarily of DataTable type.

In Laravel 5.5 you can just pass "inline" as the disposition parameter of the download function:

return response()->download('/path/to/file.pdf', 'example.pdf', [], 'inline');

The easiest way is to JSON-encode your object and then decode it back to an array:

$array = json_decode(json_encode($object), true);

Or if you prefer, you can traverse the object manually, too:

foreach ($object as $value) 
    $array[] = $value->post_id;

For python 3.7 on ubuntu I had to use sudo apt-get install python3.7-tk to make it work

It's not a good coding to put PHP code into CSS

that's it

let label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 21))
label.center = CGPoint(x: 160, y: 285)
label.textAlignment = .center
label.text = "My label"
self.view.addSubview(label)

Try above code in ViewDidLoad

$.post('mail.php',{name:$('#name').val(),
                          email:$('#e-mail').val(),
                          phone:$('#phone').val(),
                          message:$('#message').val()},

        //return the data
        function(data){
           if(data==<when do you want to clear the form>){

           $('#<form Id>').find(':input').each(function() {
                 switch(this.type) {
                      case 'password':
                      case 'select-multiple':
                      case 'select-one':

   $("#datepicker").datepicker({
     dateFormat:'dd/M/yy',
     minDate: 'now',
     changeMonth:true,

     showOn: "focus",

     buttonImageOnly: true, 
     yearRange: "-100:+0",  
  }); 

  $( "#datepicker" ).datepicker( "option", "disabled", true ); //missing ID selector

I think you should move the variable declaration to top of block. I.e.

{
    foo();
    int i = 0;
    bar();
}

to

{
    int i = 0;
    foo();
    bar();
}

Honestly, I hate all the solutions I've seen so far, and I'll tell you why: They just don't seem to ever align it right...so here's what I usually do:

I know what pixel values each div and their respective margins hold...so I do the following.

I'll create a wrapper div that has an absolute position and a left value of 50%...so this div now starts in the middle of the screen, and then I subtract half of all the content of the div's width...and I get BEAUTIFULLY scaling content...and I think this works across all browsers, too. Try it for yourself (this example assumes all content on your site is wrapped in a div tag that uses this wrapper class and all content in it is 200px in width):

.wrapper {
    position: absolute;
    left: 50%;
    margin-left: -100px;
}

EDIT: I forgot to add...you may also want to set width: 0px; on this wrapper div for some browsers to not show the scrollbars, and then you may use absolute positioning for all inner divs.

This also works AMAZING for vertically aligning your content as well using top: 50% and margin-top. Cheers!

You can use:

Object instance = new SomeClass();
instance.getClass().getName(); //will return the name (as String) (== "SomeClass")
instance.getClass(); //will return the SomeClass' Class object

HTH. But I think most of the time it is no good practice to use that for control flow or something similar...

I set the below 3 styles to my img tag

max-height: 500px;
height: 70%;
width: auto;

What it does that for desktop screen img doesn't grow beyond 500px but for small mobile screens, it will shrink to 70% of the outer container. Works like a charm.

It also works width property.

I used a try - catch block to solve the issue temporarily.

// Unregister Observer - Stop monitoring the underlying data source.
        if (mDataSetChangeObserver != null) {
            // Sometimes the Fragment onDestroy() unregisters the observer before calling below code
            // See <a>http://stackoverflow.com/questions/6165070/receiver-not-registered-exception-error</a>
            try  {
                getContext().unregisterReceiver(mDataSetChangeObserver);
                mDataSetChangeObserver = null;
            }
            catch (IllegalArgumentException e) {
                // Check wether we are in debug mode
                if (BuildConfig.IS_DEBUG_MODE) {
                    e.printStackTrace();
                }
            }
        }

If you want to work with $?, you'll need to check it after each command, since $? is updated after each command exits. This means that if you execute a pipeline, you'll only get the exit code of the last process in the pipeline.

Another approach is to do this:

set -e
set -o pipefail

If you put this at the top of the shell script, it looks like Bash will take care of this for you. As a previous poster noted, "set -e" will cause Bash to exit with an error on any simple command. "set -o pipefail" will cause Bash to exit with an error on any command in a pipeline as well.

See here or here for a little more discussion on this problem. Here is the Bash manual section on the set builtin.

This is my simple take on this question, I hope it helps someone out oneday, somewhere...

let output = document.getElementById('stopwatch');
let ms = 0;
let sec = 0;
let min = 0;

function timer() {
    ms++;
    if(ms >= 100){
        sec++
        ms = 0
    }
    if(sec === 60){
        min++
        sec = 0
    }
    if(min === 60){
        ms, sec, min = 0;
    }

    //Doing some string interpolation
    let milli = ms < 10 ? `0`+ ms : ms;
    let seconds = sec < 10 ? `0`+ sec : sec;
    let minute = min < 10 ? `0` + min : min;

    let timer= `${minute}:${seconds}:${milli}`;
    output.innerHTML =timer;
};
//Start timer
function start(){
 time = setInterval(timer,10);
}
//stop timer
function stop(){
    clearInterval(time)
}
//reset timer
function reset(){
    ms = 0;
    sec = 0;
    min = 0;

    output.innerHTML = `00:00:00`
}
const startBtn = document.getElementById('startBtn');
const stopBtn =  document.getElementById('stopBtn');
const resetBtn = document.getElementById('resetBtn');

startBtn.addEventListener('click',start,false);
stopBtn.addEventListener('click',stop,false);
resetBtn.addEventListener('click',reset,false);

    <p class="stopwatch" id="stopwatch">
        <!-- stopwatch goes here -->

I eventually figured out there was a byte mark exception and removed it using this code:

 string _byteOrderMarkUtf8 = Encoding.UTF8.GetString(Encoding.UTF8.GetPreamble());
    if (xml.StartsWith(_byteOrderMarkUtf8))
    {
        var lastIndexOfUtf8 = _byteOrderMarkUtf8.Length-1;
        xml = xml.Remove(0, lastIndexOfUtf8);
    }

you have to override CLLocationManager.didUpdateLocations

 func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    let userLocation:CLLocation = locations[0] as CLLocation
    locationManager.stopUpdatingLocation()

    let location = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude, longitude: userLocation.coordinate.longitude)

    let span = MKCoordinateSpanMake(0.5, 0.5)

    let region = MKCoordinateRegion (center:  location,span: span)

    mapView.setRegion(region, animated: true)
}

you also have to add NSLocationWhenInUseUsageDescription and NSLocationAlwaysUsageDescription to your plist setting Result as value

Include When you Include a module into your class as shown below, it’s as if you took the code defined within the module and inserted it within the class, where you ‘include’ it. It allows the ‘mixin’ behavior. It’s used to DRY up your code to avoid duplication, for instance, if there were multiple classes that would need the same code within the module.

Load The load method is almost like the require method except it doesn’t keep track of whether or not that library has been loaded. So it’s possible to load a library multiple times and also when using the load method you must specify the “.rb” extension of the library file name.

Require The require method allows you to load a library and prevents it from being loaded more than once. The require method will return ‘false’ if you try to load the same library after the first time. The require method only needs to be used if library you are loading is defined in a separate file, which is usually the case.

You can prefer this http://ionrails.com/2009/09/19/ruby_require-vs-load-vs-include-vs-extend/

My solution without using moment is to convert it to a timestamp, add the timezone offset, then convert back to a date object, and then run the toISOString()

var date = new Date(); // Or the date you'd like converted.
var isoDateTime = new Date(date.getTime() - (date.getTimezoneOffset() * 60000)).toISOString();

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

If you just want to detect mobile devices in generel, Cake has build in support using RequestHandler->isMobile() (http://book.cakephp.org/2.0/en/core-libraries/components/request-handling.html#RequestHandlerComponent::isMobile)

Since there is only one WiFi hardware on the computer its not possible to connect one WiFi hardware to multiple WiFi networks, if you want to that I think you have to map WiFi hardware to guest OS and how host you'll have to use some other hardware (may be Ethernet) but I'm sure that it will work in that way as no VM software allow us to allocate Hardware to Guest except for USB, you can also get USB WiFI and allocate that to VM only.

For completeness here is another method for emulating INTERSECT. Note that the IN (SELECT ...) form suggested in other answers is generally more efficient.

Generally for a table called mytable with a primary key called id:

SELECT id
FROM mytable AS a
INNER JOIN mytable AS b ON a.id = b.id
WHERE
(a.col1 = "someval")
AND
(b.col1 = "someotherval")

(Note that if you use SELECT * with this query you will get twice as many columns as are defined in mytable, this is because INNER JOIN generates a Cartesian product)

The INNER JOIN here generates every permutation of row-pairs from your table. That means every combination of rows is generated, in every possible order. The WHERE clause then filters the a side of the pair, then the b side. The result is that only rows which satisfy both conditions are returned, just like intersection two queries would do.

This answer was pulled from http://www.databasejournal.com/features/mssql/article.php/3683181

This same example can be used for any adhoc queries. Let us execute the stored procedure “sp_helpdb” as shown below.

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=HOME\SQLEXPRESS;Database=master;Integrated Security=True"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = "sp_helpdb"
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()
$DataSet.Tables[0]

More portable to use ed; some systems don't support \n in sed

for more details about context, read this article. I will explain that briefly.

If you wanna know what is context you must know what it does...
for example getContext() is one of the methods that retrieve context. In getContext(), Context is tied to an Activity and its lifecycle. We can imagine Context as layer which stands behind Activity and it will live as long as Activity lives. The moment the Activity dies, Context will too. this method gives list of functionalities to activity, like:

Load Resource Values,
Layout Inflation,
Start an Activity,
Show a Dialog,
Start a Service,
Bind to a Service,
Send a Broadcast,
Register BroadcastReceiver.

now imagine that :

Context is a layer(interface) which stands behind its component (Activity, Application…) and component’s lifecycle, which provides access to various functionalities which are supported by application environment and Android framework.

You can achieve this with this simple CSS/HTML:

.image-container {
    position: relative;
    width: 200px;
    height: 300px;
}
.image-container .after {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    display: none;
    color: #FFF;
}
.image-container:hover .after {
    display: block;
    background: rgba(0, 0, 0, .6);
}

HTML

<div class="image-container">
    <img src="http://lorempixel.com/300/200" />
    <div class="after">This is some content</div>
</div>

The first one catches all subclasses of Throwable (this includes Exception and Error), the second one catches all subclasses of Exception.

Error is programmatically unrecoverable in any way and is usually not to be caught, except for logging purposes (which passes it through again). Exception is programmatically recoverable. Its subclass RuntimeException indicates a programming error and is usually not to be caught as well.

Some more facts from the numpy docs :

With syntax as numpy.concatenate((a1, a2, ...), axis=0, out=None)

axis = 0 for row-wise concatenation axis = 1 for column-wise concatenation

>>> a = np.array([[1, 2], [3, 4]])
>>> b = np.array([[5, 6]])

# Appending below last row
>>> np.concatenate((a, b), axis=0)
array([[1, 2],
       [3, 4],
       [5, 6]])

# Appending after last column
>>> np.concatenate((a, b.T), axis=1)    # Notice the transpose
array([[1, 2, 5],
       [3, 4, 6]])

# Flattening the final array
>>> np.concatenate((a, b), axis=None)
array([1, 2, 3, 4, 5, 6])

I hope it helps !

COUNT is part of pig see the manual

LOGS= LOAD 'log';
LOGS_GROUP= GROUP LOGS ALL;
LOG_COUNT = FOREACH LOGS_GROUP GENERATE COUNT(LOGS);

Well, both are very, very very very misunderstood and also two completely different things. that aren't mutually exclusive.

Static types are a restriction of the grammar of the language. Statically typed languages strictly could be said to not be context free. The simple truth is that it becomes inconvenient to express a language sanely in context free grammars that doesn't treat all its data simply as bit vectors. Static type systems are part of the grammar of the language if any, they simply restrict it more than a context free grammar could, grammatical checks thus happen in two passes over the source really. Static types correspond to the mathematical notion of type theory, type theory in mathematics simply restricts the legality of some expressions. Like, I can't say 3 + [4,7] in maths, this is because of the type theory of it.

Static types are thus not a way to 'prevent errors' from a theoretical perspective, they are a limitation of the grammar. Indeed, provided that +, 3 and intervals have the usual set theoretical definitions, if we remove the type system 3 + [4,7]has a pretty well defined result that's a set. 'runtime type errors' theoretically do not exist, the type system's practical use is to prevent operations that to human beings would make no sense. Operations are still just the shifting and manipulation of bits of course.

The catch to this is that a type system can't decide if such operations are going to occur or not if it would be allowed to run. As in, exactly partition the set of all possible programs in those that are going to have a 'type error', and those that aren't. It can do only two things:

1: prove that type errors are going to occur in a program
2: prove that they aren't going to occur in a program

This might seem like I'm contradicting myself. But what a C or Java type checker does is it rejects a program as 'ungrammatical', or as it calls it 'type error' if it can't succeed at 2. It can't prove they aren't going to occur, that doesn't mean that they aren't going to occur, it just means it can't prove it. It might very well be that a program which will not have a type error is rejected simply because it can't be proven by the compiler. A simple example being if(1) a = 3; else a = "string";, surely since it's always true, the else-branch will never be executed in the program, and no type error shall occur. But it can't prove these cases in a general way, so it's rejected. This is the major weakness of a lot of statically typed languages, in protecting you against yourself, you're necessarily also protected in cases you don't need it.

But, contrary to popular believe, there are also statically typed languages that work by principle 1. They simply reject all programs of which they can prove it's going to cause a type error, and pass all programs of which they can't. So it's possible they allow programs which have type errors in them, a good example being Typed Racket, it's hybrid between dynamic and static typing. And some would argue that you get the best of both worlds in this system.

Another advantage of static typing is that types are known at compile time, and thus the compiler can use this. If we in Java do "string" + "string" or 3 + 3, both + tokens in text in the end represent a completely different operation and datum, the compiler knows which to choose from the types alone.

Now, I'm going to make a very controversial statement here but bear with me: 'dynamic typing' does not exist.

Sounds very controversial, but it's true, dynamically typed languages are from a theoretical perspective untyped. They are just statically typed languages with only one type. Or simply put, they are languages that are indeed grammatically generated by a context free grammar in practice.

Why don't they have types? Because every operation is defined and allowed on every operant, what's a 'runtime type error' exactly? It's from a theoretical example purely a side-effect. If doing print("string") which prints a string is an operation, then so is length(3), the former has the side effect of writing string to the standard output, the latter simply error: function 'length' expects array as argument., that's it. There is from a theoretical perspective no such thing as a dynamically typed language. They are untyped

All right, the obvious advantage of 'dynamically typed' language is expressive power, a type system is nothing but a limitation of expressive power. And in general, languages with a type system indeed would have a defined result for all those operations that are not allowed if the type system was just ignored, the results would just not make sense to humans. Many languages lose their Turing completeness after applying a type system.

The obvious disadvantage is the fact that operations can occur which would produce results which are nonsensical to humans. To guard against this, dynamically typed languages typically redefine those operations, rather than producing that nonsensical result they redefine it to having the side effect of writing out an error, and possibly halting the program altogether. This is not an 'error' at all, in fact, the language specification usually implies this, this is as much behaviour of the language as printing a string from a theoretical perspective. Type systems thus force the programmer to reason about the flow of the code to make sure that this doesn't happen. Or indeed, reason so that it does happen can also be handy in some points for debugging, showing that it's not an 'error' at all but a well defined property of the language. In effect, the single remnant of 'dynamic typing' that most languages have is guarding against a division by zero. This is what dynamic typing is, there are no types, there are no more types than that zero is a different type than all the other numbers. What people call a 'type' is just another property of a datum, like the length of an array, or the first character of a string. And many dynamically typed languages also allow you to write out things like "error: the first character of this string should be a 'z'".

Another thing is that dynamically typed languages have the type available at runtime and usually can check it and deal with it and decide from it. Of course, in theory it's no different than accessing the first char of an array and seeing what it is. In fact, you can make your own dynamic C, just use only one type like long long int and use the first 8 bits of it to store your 'type' in and write functions accordingly that check for it and perform float or integer addition. You have a statically typed language with one type, or a dynamic language.

In practise this all shows, statically typed languages are generally used in the context of writing commercial software, whereas dynamically typed languages tend to be used in the context of solving some problems and automating some tasks. Writing code in statically typed languages simply takes long and is cumbersome because you can't do things which you know are going to turn out okay but the type system still protects you against yourself for errors you don't make. Many coders don't even realize that they do this because it's in their system but when you code in static languages, you often work around the fact that the type system won't let you do things that can't go wrong, because it can't prove it won't go wrong.

As I noted, 'statically typed' in general means case 2, guilty until proven innocent. But some languages, which do not derive their type system from type theory at all use rule 1: Innocent until proven guilty, which might be the ideal hybrid. So, maybe Typed Racket is for you.

Also, well, for a more absurd and extreme example, I'm currently implementing a language where 'types' are truly the first character of an array, they are data, data of the 'type', 'type', which is itself a type and datum, the only datum which has itself as a type. Types are not finite or bounded statically but new types may be generated based on runtime information.

This might be too late for your work, but here is how I did it. I want something run everyday at 1AM - I believe this is similar to what you are doing. Here is how I did it:

CREATE EVENT event_name
  ON SCHEDULE
    EVERY 1 DAY
    STARTS (TIMESTAMP(CURRENT_DATE) + INTERVAL 1 DAY + INTERVAL 1 HOUR)
  DO
    # Your awesome query

If, at some point, you only need to export a single result set, just right click "on the data" (any column of any row) there you will find an export option. The wizard exports the complete result set regardless of what you selected

I prefer the JPA2 EntityManager API over SessionFactory, because it feels more modern. One simple example:

JPA:

@PersistenceContext
EntityManager entityManager;

public List<MyEntity> findSomeApples() {
  return entityManager
     .createQuery("from MyEntity where apples=7", MyEntity.class)
     .getResultList();
}

SessionFactory:

@Autowired
SessionFactory sessionFactory;

public List<MyEntity> findSomeApples() {
  Session session = sessionFactory.getCurrentSession();
  List<?> result = session.createQuery("from MyEntity where apples=7")
      .list();
  @SuppressWarnings("unchecked")
  List<MyEntity> resultCasted = (List<MyEntity>) result;
  return resultCasted;
}

I think it's clear that the first one looks cleaner and is also easier to test because EntityManager can be easily mocked.

With fscanf read the file until you encounter ';' or \n, then you can just skip it with fscang(f, "%*c").

int main()
{
    char str[128];
    int result;
    FILE* f = fopen("test.txt", "r");
    ...
    
    do {
        result = fscanf(f, "%127[^;\n]", str);
        
        if(result == 0)
        {
            result = fscanf(f, "%*c");
        }
        else
        {
            //whatever you want to do with your value
            printf("%s\n", str);
        }
        
    } while(result != EOF);

    return 0;
}

You should implement the method __eq__:

 class MyClass:
      def __init__(self, foo, bar, name):
           self.foo = foo
           self.bar = bar
           self.name = name

      def __eq__(self,other):
           if not isinstance(other,MyClass):
                return NotImplemented
           else:
                #string lists of all method names and properties of each of these objects
                prop_names1 = list(self.__dict__)
                prop_names2 = list(other.__dict__)

                n = len(prop_names1) #number of properties
                for i in range(n):
                     if getattr(self,prop_names1[i]) != getattr(other,prop_names2[i]):
                          return False

                return True

As others have mentioned, using an XML library is the easiest way. If you do want to escape yourself, you could look into StringEscapeUtils from the Apache Commons Lang library.

If your regex includes a variable, make sure to escape it.

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

This can be used like this

new RegExp(escapeRegExp(searchString), 'i')

Or in a mongoDb query like this

{ '$regex': escapeRegExp(searchString) }

Look at this one: Convert List/IEnumerable to DataTable/DataView

In my code I changed it into a extension method:

public static DataTable ToDataTable<T>(this List<T> items)
{
    var tb = new DataTable(typeof(T).Name);

    PropertyInfo[] props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);

    foreach(var prop in props)
    {
        tb.Columns.Add(prop.Name, prop.PropertyType);
    }

     foreach (var item in items)
    {
       var values = new object[props.Length];
        for (var i=0; i<props.Length; i++)
        {
            values[i] = props[i].GetValue(item, null);
        }

        tb.Rows.Add(values);
    }

    return tb;
}

Try this:

x = "{{ Hello }} {0}"

A bit of a late answer I know, but I just had the same problem and decided that Python's internal range function was a bit lacking in this respect so I've overridden it in a util module of mine.

from __builtin__ import range as _range
from datetime import datetime, timedelta

def range(*args):
    if len(args) != 3:
        return _range(*args)
    start, stop, step = args
    if start < stop:
        cmp = lambda a, b: a < b
        inc = lambda a: a + step
    else:
        cmp = lambda a, b: a > b
        inc = lambda a: a - step
    output = [start]
    while cmp(start, stop):
        start = inc(start)
        output.append(start)

    return output

print range(datetime(2011, 5, 1), datetime(2011, 10, 1), timedelta(days=30))

Based on the C99 Specification: a == (a / b) * b + a % b

We can write a function to calculate (a % b) == a - (a / b) * b!

int remainder(int a, int b)
{
    return a - (a / b) * b;
}

For modulo operation, we can have the following function (assuming b > 0)

int mod(int a, int b)
{
    int r = a % b;
    return r < 0 ? r + b : r;
}

My conclusion is that a % b in C is a remainder operation and NOT a modulo operation.

You can use the Content property on pretty much all visual WPF controls to access the stuff inside them. There's a heirarchy of classes that the controls belong to, and any descendants of ContentControl will work in this way.

$("#datepicker").datepicker("setDate", new Date);

Got it in the end. My Custom ModelBinder which was not being registered and does this :

var mymsPage = new MyCmsPage();

NameValueCollection frm = controllerContext.HttpContext.Request.Form;

myCmsPage.SeoTitle = (!String.IsNullOrEmpty(frm["seoTitle"])) ? frm["seoTitle"] : null;

So something that the default model binding was doing must have been causing the problem. Not sure what, but my problem is at least fixed now that my custom model binder is being registered.

I added the vendor prefixes, and changed the animation to all, so you have both opacity and width that are animated.

Is this what you're looking for ? http://jsfiddle.net/u2FKM/3/

Try:

The legitimate way to do that irrespective of size of the div for any browser size is :

Live Code

the year function dose, like this:

select year(date_column) from table_name

My suggestions :

• Keep the program modular. Keep the Calculate class in a separate Calculate.java file and create a new class that calls the main method. This would make the code readable.

• For setting the values in the number, use constructors. Do not use like the methods you have used above like :

  public void setNumber(double fnum, double snum){ this.fn = fnum; this.sn = snum; }

  Constructors exists to initialize the objects.This is their job and they are pretty good at it.

• Getters for members of Calculate class seem in place. But setters are not. Getters and setters serves as one important block in the bridge of efficient programming with java. Put setters for fnum and snum as well

• In the main class, create a Calculate object using the new operator and the constructor in place.

• Call the getAnswer() method with the created Calculate object.

Rest of the code looks fine to me. Be modular. You could read your program in a much better way.

Here is my modular piece of code. Two files : Main.java & Calculate.java

Calculate.java

public class Calculate {


private double fn;
private double sn;
private char op;

    public double getFn() {
        return fn;
    }

    public void setFn(double fn) {
        this.fn = fn;
    }

    public double getSn() {
        return sn;
    }

    public void setSn(double sn) {
        this.sn = sn;
    }

    public char getOp() {
        return op;
    }

    public void setOp(char op) {
        this.op = op;
    }



    public Calculate(double fn, double sn, char op) {
        this.fn = fn;
        this.sn = sn;
        this.op = op;
    }


public void getAnswer(){
    double ans;
    switch (getOp()){
        case '+': 
            ans = add(getFn(), getSn());
            ansOutput(ans);
            break;
        case '-': 
            ans = sub (getFn(), getSn());
            ansOutput(ans);
            break;
        case '*': 
            ans = mul (getFn(), getSn());
            ansOutput(ans);
            break;
        case '/': 
            ans = div (getFn(), getSn());
            ansOutput(ans);
            break;
        default:
            System.out.println("--------------------------");
            System.out.println("Invalid choice of operator");
            System.out.println("--------------------------");
        }
    }
    public static double add(double x,double y){
        return x + y;
    }
    public static double sub(double x, double y){
        return x - y;
    }
    public static double mul(double x, double y){
        return x * y;
    }
    public static double div(double x, double y){
        return x / y;
    }

    public static void ansOutput(double x){
        System.out.println("----------- -------");
        System.out.printf("the answer is %.2f\n", x);
        System.out.println("-------------------");
    }
}

Main.java

public class Main {
    public static void main(String args[])
    {
        Calculate obj = new Calculate(1,2,'+');
        obj.getAnswer();
    }
}

If the XML have identities with same name in different levels there is a solution. You don´t have to ever submit a raw XML (this PHP SOAP object don´t allows send a RAW XML), so you have to always translate your XML to a array, like the example below:

$originalXML = "
<xml>
  <firstClient>
      <name>someone</name>
      <adress>R. 1001</adress>
  </firstClient>
  <secondClient>
      <name>another one</name>
      <adress></adress>
  </secondClient>
</xml>"

//Translate the XML above in a array, like PHP SOAP function requires
$myParams = array('firstClient' => array('name' => 'someone',
                                  'adress' => 'R. 1001'),
            'secondClient' => array('name' => 'another one',
                                  'adress' => ''));

$webService = new SoapClient($someURL);
$result = $webService->someWebServiceFunction($myParams);

or

$soapUrl = "http://privpakservices.schenker.nu/package/package_1.3/packageservices.asmx?op=SearchCollectionPoint";

$xml_post_string = '<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><SearchCollectionPoint xmlns="http://privpakservices.schenker.nu/"><customerID>XXX</customerID><key>XXXXXX-XXXXXX</key><serviceID></serviceID><paramID>0</paramID><address>RiksvŠgen 5</address><postcode>59018</postcode><city>Mantorp</city><maxhits>10</maxhits></SearchCollectionPoint></soap12:Body></soap12:Envelope>';

A few things happening here:

1. I assume you required fs/http, and set the dir variable :)
2. google.com redirects to www.google.com, so you're saving the redirect response's body, not the image
3. the response is streamed. that means the 'data' event fires many times, not once. you have to save and join all the chunks together to get the full response body
4. since you're getting binary data, you have to set the encoding accordingly on response and writeFile (default is utf8)

This should work:

var http = require('http')
  , fs = require('fs')
  , options

options = {
    host: 'www.google.com'
  , port: 80
  , path: '/images/logos/ps_logo2.png'
}

var request = http.get(options, function(res){
    var imagedata = ''
    res.setEncoding('binary')

    res.on('data', function(chunk){
        imagedata += chunk
    })

    res.on('end', function(){
        fs.writeFile('logo.png', imagedata, 'binary', function(err){
            if (err) throw err
            console.log('File saved.')
        })
    })

})

You want to do something like the following:

• Open the old file for reading
• Open a new (temporary) file for writing
• Iterate over the lines in the old file (probably using a BufferedReader)
  • For each line, check if it matches what you are supposed to remove
  • If it matches, do nothing
  • If it doesn't match, write it to the temporary file
• When done, close both files
• Delete the old file
• Rename the temporary file to the name of the original file

(I won't write the actual code, since this looks like homework, but feel free to post other questions on specific bits that you have trouble with)

Rather than preg_replace, you could always use PHP's filter functions using the filter_var() function with FILTER_SANITIZE_STRING.

No, it sets all members/elements that haven't been explicitly set to their default-initialisation value, which is zero for numeric types.

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

Answering late to mention yet another option rather than the common MAVEN_OPTS environment variable to pass to the Maven build the required JVM options.

Since Maven 3.3.1, you could have an .mvn folder as part of the concerned project and a jvm.config file as perfect place for such an option.

two new optional configuration files .mvn/jvm.config and .mvn/maven.config, located at the base directory of project source tree. If present, these files will provide default jvm and maven options. Because these files are part of the project source tree, they will be present in all project checkouts and will be automatically used every time the project is build.

As part of the official release notes

In Maven it is not simple to define JVM configuration on a per project base. The existing mechanism based on an environment variable MAVEN_OPTS and the usage of ${user.home}/.mavenrc is an other option with the drawback of not being part of the project.

Starting with this release you can define JVM configuration via ${maven.projectBasedir}/.mvn/jvm.config file which means you can define the options for your build on a per project base. This file will become part of your project and will be checked in along with your project. So no need anymore for MAVEN_OPTS, .mavenrc files. So for example if you put the following JVM options into the ${maven.projectBasedir}/.mvn/jvm.config file:

-Xmx2048m -Xms1024m -XX:MaxPermSize=512m -Djava.awt.headless=true

The main advantage of this approach is that the configuration is isolated to the concerned project and applied to the whole build as well, and less fragile than MAVEN_OPTS for other developers working on the same project (forgetting to setting it).
Moreover, the options will be applied to all modules in case of a multi-module project.

The primary purpose of the DataFrame indexing operator, [] is to select columns.

When the indexing operator is passed a string or integer, it attempts to find a column with that particular name and return it as a Series.

So, in the question above: df[2] searches for a column name matching the integer value 2. This column does not exist and a KeyError is raised.

The DataFrame indexing operator completely changes behavior to select rows when slice notation is used

Strangely, when given a slice, the DataFrame indexing operator selects rows and can do so by integer location or by index label.

df[2:3]

This will slice beginning from the row with integer location 2 up to 3, exclusive of the last element. So, just a single row. The following selects rows beginning at integer location 6 up to but not including 20 by every third row.

df[6:20:3]

You can also use slices consisting of string labels if your DataFrame index has strings in it. For more details, see this solution on .iloc vs .loc.

I almost never use this slice notation with the indexing operator as its not explicit and hardly ever used. When slicing by rows, stick with .loc/.iloc.

import 'core-js/es7/array' 

into polyfill.ts worked for me.

 grep "subscription" | grep -v "spec"  

This code worked fine for me.

 import java.io.FileOutputStream;
 import java.io.IOException;
 import java.io.InputStream;
 import java.io.OutputStream;
 import java.net.URL;

public class SaveImageFromUrl {

public static void main(String[] args) throws Exception {
    String imageUrl = "http://www.avajava.com/images/avajavalogo.jpg";
    String destinationFile = "image.jpg";

    saveImage(imageUrl, destinationFile);
}

public static void saveImage(String imageUrl, String destinationFile) throws IOException {
    URL url = new URL(imageUrl);
    InputStream is = url.openStream();
    OutputStream os = new FileOutputStream(destinationFile);

    byte[] b = new byte[2048];
    int length;

    while ((length = is.read(b)) != -1) {
        os.write(b, 0, length);
    }

    is.close();
    os.close();
}

}

When you create your own key pair object, you should face a few thing.

First, you should be aware of implementing hashCode() and equals(). You will need to do this.

Second, when implementing hashCode(), make sure you understand how it works. The given user example

public int hashCode() {
    return this.x ^ this.y;
}

is actually one of the worst implementations you can do. The reason is simple: you have a lot of equal hashes! And the hashCode() should return int values that tend to be rare, unique at it's best. Use something like this:

public int hashCode() {
  return (X << 16) + Y;
}

This is fast and returns unique hashes for keys between -2^16 and 2^16-1 (-65536 to 65535). This fits in almost any case. Very rarely you are out of this bounds.

Third, when implementing equals() also know what it is used for and be aware of how you create your keys, since they are objects. Often you do unnecessary if statements cause you will always have the same result.

If you create keys like this: map.put(new Key(x,y),V); you will never compare the references of your keys. Cause everytime you want to acces the map, you will do something like map.get(new Key(x,y));. Therefore your equals() does not need a statement like if (this == obj). It will never occure.

Instead of if (getClass() != obj.getClass()) in your equals() better use if (!(obj instanceof this)). It will be valid even for subclasses.

So the only thing you need to compare is actually X and Y. So the best equals() implementation in this case would be:

public boolean equals (final Object O) {
  if (!(O instanceof Key)) return false;
  if (((Key) O).X != X) return false;
  if (((Key) O).Y != Y) return false;
  return true;
}

So in the end your key class is like this:

public class Key {

  public final int X;
  public final int Y;

  public Key(final int X, final int Y) {
    this.X = X;
    this.Y = Y;
  }

  public boolean equals (final Object O) {
    if (!(O instanceof Key)) return false;
    if (((Key) O).X != X) return false;
    if (((Key) O).Y != Y) return false;
    return true;
  }

  public int hashCode() {
    return (X << 16) + Y;
  }

}

You can give your dimension indices X and Y a public access level, due to the fact they are final and do not contain sensitive information. I'm not a 100% sure whether private access level works correctly in any case when casting the Object to a Key.

If you wonder about the finals, I declare anything as final which value is set on instancing and never changes - and therefore is an object constant.

Taking into account file one should first get a java.io.Reader instance. This can then be read and added to a StringBuilder (we don't need StringBuffer if we are not accessing it in multiple threads, and StringBuilder is faster). The trick here is that we work in blocks, and as such don't need other buffering streams. The block size is parameterized for run-time performance optimization.

public static String slurp(final InputStream is, final int bufferSize) {
    final char[] buffer = new char[bufferSize];
    final StringBuilder out = new StringBuilder();
    try (Reader in = new InputStreamReader(is, "UTF-8")) {
        for (;;) {
            int rsz = in.read(buffer, 0, buffer.length);
            if (rsz < 0)
                break;
            out.append(buffer, 0, rsz);
        }
    }
    catch (UnsupportedEncodingException ex) {
        /* ... */
    }
    catch (IOException ex) {
        /* ... */
    }
    return out.toString();
}

The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard. .jpeg and .jpg files are identical. JPEG images are identified with 6 different standard file name extensions:

• .jpg
• .jpeg
• .jpe
• .jif
• .jfif
• .jfi

The jpg was used in Microsoft Operating Systems when they only supported 3 chars-extensions.

The JPEG File Interchange Format (JFIF - last three extensions in my list) is an image file format standard for exchanging JPEG encoded files compliant with the JPEG Interchange Format (JIF) standard, solving some of JIF's limitations in regard. Image data in JFIF files is compressed using the techniques in the JPEG standard, hence JFIF is sometimes referred to as "JPEG/JFIF".

Drawing from T.J. Crowder's solution, I created a prototype to deal with this problem:

Array.prototype.check = function (s) {
  return this.some((v) => {
    return s.indexOf(v) >= 0;
  });
};

For the sake of others who are wondering on how to get to this window. Here's how:

You can access this by clicking on Select Run/Debug Configurations (to the left of ) and going to the Edit Configurations. A gif provided for clarity.

Currently, Firefox honors the language of the HTML element in which the input resides. For example, try this fiddle in Firefox:

http://jsfiddle.net/ashraf_sabry_m/yzzhop75/1/

You will see that the numerals are in Arabic, and the comma is used as the decimal separator, which is the case with Arabic. This is because the BODY tag is given the attribute lang="ar-EG".

Next, try this one:

http://jsfiddle.net/ashraf_sabry_m/yzzhop75/2/

This one is displayed with a dot as the decimal separator because the input is wrapped in a DIV given the attribute lang="en-US".

So, a solution you may resort to is to wrap your numeric inputs with a container element that is set to use a culture that uses dots as the decimal separator.

purple.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Fragment fragment = new tasks();
        FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.content_frame, fragment);
        fragmentTransaction.addToBackStack(null);
        fragmentTransaction.commit();
    }
});

you write the above code...there we are replacing R.id.content_frame with our fragment. hope this helps you
