There are two distinct but closely related problems in establishing a secure communication

1. Encrypt data so that only authorized persons can decrypt and read it.
2. Verify the identity/authentication of sender.

Both of these problems can be elegantly solved using public key cryptography.

I. Encryption and decryption of data

Alice wants to send a message to Bob which no one should be able to read.

• Alice encrypts the message with Bob's public key and sends it over.
• Bob receives the message and decrypts it using his private Key.

Note that if A wants to send a message to B, A needs to use the Public key of B (which is publicly available to anyone) and neither public nor private key of A comes into picture here.

So if you want to send a message to me you should know and use my public key which I provide to you and only I will be able to decrypt the message since I am the only one who has access to the corresponding private key.

II. Verify the identity of sender (Authentication)

Alice wants to send a message to Bob again. The problem of encrypting the data is solved using the above method.

But what if I am sitting between Alice and Bob, introducing myself as 'Alice' to Bob and sending my own message to Bob instead of forwarding the one sent by Alice. Even though I can not decrypt and read the original message sent by Alice(that requires access to Bob's private key) I am hijacking the entire conversation between them.

Is there a way Bob can confirm that the messages he is receiving are actually sent by Alice?

• Alice signs the message with her private key and sends it over. (In practice, what is signed is a hash of the message, e.g. SHA-256 or SHA-512.)
• Bob receives it and verifies it using Alice's public key. Since Alice's public key successfully verified the message, Bob can conclude that the message has been signed by Alice.

The SQL you want is

select name from studens where id in (1, 5, 8)

If you want to construct this from the python you could use

l = [1, 5, 8]
sql_query = 'select name from studens where id in (' + ','.join(map(str, l)) + ')'

The map function will transform the list into a list of strings that can be glued together by commas using the str.join method.

Alternatively:

l = [1, 5, 8]
sql_query = 'select name from studens where id in (' + ','.join((str(n) for n in l)) + ')'

if you prefer generator expressions to the map function.

UPDATE: S. Lott mentions in the comments that the Python SQLite bindings don't support sequences. In that case, you might want

select name from studens where id = 1 or id = 5 or id = 8

Generated by

sql_query = 'select name from studens where ' + ' or '.join(('id = ' + str(n) for n in l))

Instead of doing all these.. cant you use a simpler approach as shown below.

Response.ClearContent();
            Response.AddHeader("content-disposition", "attachment; filename=" + strFileName);
            Response.ContentType = "application/excel";
            System.IO.StringWriter sw = new System.IO.StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);
            gv.RenderControl(htw);
            Response.Write(sw.ToString());
            Response.End();

This is working for me using this Bootsrap Datetimepiker, it returns the value as it is shown in the datepicker input, e.g. 2019-04-11

$('#myDateTimePicker').on('click,focusout', function (){
    var myDate = $("#myDateTimePicker").val();
    //console.log(myDate);
    //alert(myDate);
});

Addendum to @ideasman42's answer:

def saveAsPNG(array, filename):
    import struct
    if any([len(row) != len(array[0]) for row in array]):
        raise ValueError, "Array should have elements of equal size"

                                #First row becomes top row of image.
    flat = []; map(flat.extend, reversed(array))
                                 #Big-endian, unsigned 32-byte integer.
    buf = b''.join([struct.pack('>I', ((0xffFFff & i32)<<8)|(i32>>24) )
                    for i32 in flat])   #Rotate from ARGB to RGBA.

    data = write_png(buf, len(array[0]), len(array))
    f = open(filename, 'wb')
    f.write(data)
    f.close()

So you can do:

saveAsPNG([[0xffFF0000, 0xffFFFF00],
           [0xff00aa77, 0xff333333]], 'test_grid.png')

Producing test_grid.png:

(Transparency also works, by reducing the high byte from 0xff.)

Here's a simple solution using OkHttp, Future, ExecutorService and Callable:

final OkHttpClient httpClient = new OkHttpClient();
final ExecutorService executor = newFixedThreadPool(3);

final Request request = new Request.Builder().url("http://example.com").build();

Response response = executor.submit(new Callable<Response>() {
   public Response call() throws IOException {
      return httpClient.newCall(request).execute();
   }
}).get();

If you simply want to add it without creating a new class try this:

// WPF
<ComboBox Name="language" Loaded="language_Loaded" /> 


// C# code
private void language_Loaded(object sender, RoutedEventArgs e)
{
    List<String> language= new List<string>();
    language.Add("English");
    language.Add("Spanish");
    language.Add("ect"); 
    this.chartReviewComboxBox.ItemsSource = language;
}

I suggest an xml file with all your languages that you will support that way you do not have to be dependent on c# I would definitly create a class for languge like the above programmer suggest.

What you want is perfectly reasonable when test cases are being run as a suite.

Unfortunately no time to give a complete solution right now, but have a look at class:

org.junit.runners.Suite

Which allows you to call test cases (from any test class) in a specific order.

These might be used to create functional, integration or system tests.

This leaves your unit tests as they are without specific order (as recommended), whether you run them like that or not, and then re-use the tests as part of a bigger picture.

We re-use/inherit the same code for unit, integration and system tests, sometimes data driven, sometimes commit driven, and sometimes run as a suite.

const

public const string MyStr;

is a compile time constant (you can use it as the default parameter for a method parameter for example), and it will not be obfuscated if you use such technology

static readonly

public static readonly string MyStr;

is runtime constant. It means that it is evaluated when the application is launched and not before. This is why it can't be used as the default parameter for a method (compilation error) for example. The value stored in it can be obfuscated.

As @DSM points out, you can do this more directly using the vectorised string methods:

df['Date'].str[-4:].astype(int)

Or using extract (assuming there is only one set of digits of length 4 somewhere in each string):

df['Date'].str.extract('(?P<year>\d{4})').astype(int)

An alternative slightly more flexible way, might be to use apply (or equivalently map) to do this:

df['Date'] = df['Date'].apply(lambda x: int(str(x)[-4:]))
             #  converts the last 4 characters of the string to an integer

The lambda function, is taking the input from the Date and converting it to a year.
You could (and perhaps should) write this more verbosely as:

def convert_to_year(date_in_some_format):
    date_as_string = str(date_in_some_format)  # cast to string
    year_as_string = date_in_some_format[-4:] # last four characters
    return int(year_as_string)

df['Date'] = df['Date'].apply(convert_to_year)

Perhaps 'Year' is a better name for this column...

Look into the XMLSerializer class.

If you want to save the state of objects and be able to recreate them easily at another time, serialization is your best bet.

Serialize it so you are returned the fully-formed XML. Write this to a file using the StreamWriter class.

Later, you can read in the contents of your file, and pass it to the serializer class along with an instance of the object you want to populate, and the serializer will take care of deserializing as well.

Here's a code snippet taken from Microsoft Support:

using System;

public class clsPerson
{
  public  string FirstName;
  public  string MI;
  public  string LastName;
}

class class1
{ 
   static void Main(string[] args)
   {
      clsPerson p=new clsPerson();
      p.FirstName = "Jeff";
      p.MI = "A";
      p.LastName = "Price";
      System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(p.GetType());

      // at this step, instead of passing Console.Out, you can pass in a 
      // Streamwriter to write the contents to a file of your choosing.
      x.Serialize(Console.Out, p);


      Console.WriteLine();
      Console.ReadLine();
   }
} 

  if (System.IO.File.Exists(@"C:\Users\Public\DeleteTest\test.txt"))
    {
        // Use a try block to catch IOExceptions, to 
        // handle the case of the file already being 
        // opened by another process. 
        try
        {
            System.IO.File.Delete(@"C:\Users\Public\DeleteTest\test.txt");
        }
        catch (System.IO.IOException e)
        {
            Console.WriteLine(e.Message);
            return;
        }
    }

new allocates objects on the heap. Otherwise, objects are allocated on the stack. Look up the difference between the two.

I have a setup like this:

• application
• system
• assets
  • js
  • imgs
  • css

I then have a helper function that simply returns the full path to this depending on my setup, something similar to:

application/helpers/utility_helper.php:

function asset_url(){
   return base_url().'assets/';
}

I will usually keep common routines similar to this in the same file and autoload it with codeigniter's autoload configuration.

Note: autoload URL helper for base_url() access.

application/config/autoload.php:

$autoload['helper'] = array('url','utility');

You will then have access to asset_url() throughout your code.

The following plugin-structure utilizes the jQuery-data()-method to provide a public interface to internal plugin-methods/-settings (while preserving jQuery-chainability):

(function($, window, undefined) { 
  const defaults = {
    elementId   : null,
    shape       : "square",
    color       : "aqua",
    borderWidth : "10px",
    borderColor : "DarkGray"
  };

  $.fn.myPlugin = function(options) {
    // settings, e.g.:  
    var settings = $.extend({}, defaults, options);

    // private methods, e.g.:
    var setBorder = function(color, width) {        
      settings.borderColor = color;
      settings.borderWidth = width;          
      drawShape();
    };

    var drawShape = function() {         
      $('#' + settings.elementId).attr('class', settings.shape + " " + "center"); 
      $('#' + settings.elementId).css({
        'background-color': settings.color,
        'border': settings.borderWidth + ' solid ' + settings.borderColor      
      });
      $('#' + settings.elementId).html(settings.color + " " + settings.shape);            
    };

    return this.each(function() { // jQuery chainability     
      // set stuff on ini, e.g.:
      settings.elementId = $(this).attr('id'); 
      drawShape();

      // PUBLIC INTERFACE 
      // gives us stuff like: 
      //
      //    $("#...").data('myPlugin').myPublicPluginMethod();
      //
      var myPlugin = {
        element: $(this),
        // access private plugin methods, e.g.: 
        setBorder: function(color, width) {        
          setBorder(color, width);
          return this.element; // To ensure jQuery chainability 
        },
        // access plugin settings, e.g.: 
        color: function() {
          return settings.color;
        },        
        // access setting "shape" 
        shape: function() {
          return settings.shape;
        },     
        // inspect settings 
        inspectSettings: function() {
          msg = "inspecting settings for element '" + settings.elementId + "':";   
          msg += "\n--- shape: '" + settings.shape + "'";
          msg += "\n--- color: '" + settings.color + "'";
          msg += "\n--- border: '" + settings.borderWidth + ' solid ' + settings.borderColor + "'";
          return msg;
        },               
        // do stuff on element, e.g.:  
        change: function(shape, color) {        
          settings.shape = shape;
          settings.color = color;
          drawShape();   
          return this.element; // To ensure jQuery chainability 
        }
      };
      $(this).data("myPlugin", myPlugin);
    }); // return this.each 
  }; // myPlugin
}(jQuery));

Now you can call internal plugin-methods to access or modify plugin data or the relevant element using this syntax:

$("#...").data('myPlugin').myPublicPluginMethod(); 

As long as you return the current element (this) from inside your implementation of myPublicPluginMethod() jQuery-chainability will be preserved - so the following works:

$("#...").data('myPlugin').myPublicPluginMethod().css("color", "red").html("...."); 

Here are some examples (for details checkout this fiddle):

// initialize plugin on elements, e.g.:
$("#shape1").myPlugin({shape: 'square', color: 'blue', borderColor: 'SteelBlue'});
$("#shape2").myPlugin({shape: 'rectangle', color: 'red', borderColor: '#ff4d4d'});
$("#shape3").myPlugin({shape: 'circle', color: 'green', borderColor: 'LimeGreen'});

// calling plugin methods to read element specific plugin settings:
console.log($("#shape1").data('myPlugin').inspectSettings());    
console.log($("#shape2").data('myPlugin').inspectSettings());    
console.log($("#shape3").data('myPlugin').inspectSettings());      

// calling plugin methods to modify elements, e.g.:
// (OMG! And they are chainable too!) 
$("#shape1").data('myPlugin').change("circle", "green").fadeOut(2000).fadeIn(2000);      
$("#shape1").data('myPlugin').setBorder('LimeGreen', '30px');

$("#shape2").data('myPlugin').change("rectangle", "red"); 
$("#shape2").data('myPlugin').setBorder('#ff4d4d', '40px').css({
  'width': '350px',
  'font-size': '2em' 
}).slideUp(2000).slideDown(2000);              

$("#shape3").data('myPlugin').change("square", "blue").fadeOut(2000).fadeIn(2000);   
$("#shape3").data('myPlugin').setBorder('SteelBlue', '30px');

// etc. ...     

Try this code

Convert ArrayList to Collection

  ArrayList<User> usersArrayList = new ArrayList<User>();

  Collection<User> userCollection = new HashSet<User>(usersArrayList);

Convert Collection to ArrayList

  Collection<User> userCollection = new HashSet<User>(usersArrayList);

  List<User> userList = new ArrayList<User>(userCollection );

To read the data line-by-line into a Bash array you can do this:

while read -a row
do
    echo "..${row[0]}..${row[1]}..${row[2]}.."
done < <(echo "SELECT A, B, C FROM table_a" | mysql database -u $user -p $password)

Or into individual variables:

while read a b c
do
    echo "..${a}..${b}..${c}.."
done < <(echo "SELECT A, B, C FROM table_a" | mysql database -u $user -p $password)

super late entry but GAAP is a good rule of thumb..

If your application needs to handle money values up to a trillion then this should work: 13,2 If you need to comply with GAAP (Generally Accepted Accounting Principles) then use: 13,4

Usually you should sum your money values at 13,4 before rounding of the output to 13,2.

You need to put the full path in the php ini when loading the mysql dll, i.e :-

extension=c:/php54/ext/php_mbstring.dll
extension=c:/php54/ext/php_mysql.dll

Then you don't need to move them to the windows folder.

postgresql get seconds difference between timestamps

SELECT (
    (extract (epoch from (
        '2012-01-01 18:25:00'::timestamp - '2012-01-01 18:25:02'::timestamp
                         )
             )
    )
)::integer

which prints:

-2

Because the timestamps are two seconds apart. Take the number and divide by 60 to get minutes, divide by 60 again to get hours.

The slowest possible method is to compare two files byte by byte. The fastest I've been able to come up with is a similar comparison, but instead of one byte at a time, you would use an array of bytes sized to Int64, and then compare the resulting numbers.

Here's what I came up with:

    const int BYTES_TO_READ = sizeof(Int64);

    static bool FilesAreEqual(FileInfo first, FileInfo second)
    {
        if (first.Length != second.Length)
            return false;

        if (string.Equals(first.FullName, second.FullName, StringComparison.OrdinalIgnoreCase))
            return true;

        int iterations = (int)Math.Ceiling((double)first.Length / BYTES_TO_READ);

        using (FileStream fs1 = first.OpenRead())
        using (FileStream fs2 = second.OpenRead())
        {
            byte[] one = new byte[BYTES_TO_READ];
            byte[] two = new byte[BYTES_TO_READ];

            for (int i = 0; i < iterations; i++)
            {
                 fs1.Read(one, 0, BYTES_TO_READ);
                 fs2.Read(two, 0, BYTES_TO_READ);

                if (BitConverter.ToInt64(one,0) != BitConverter.ToInt64(two,0))
                    return false;
            }
        }

        return true;
    }

In my testing, I was able to see this outperform a straightforward ReadByte() scenario by almost 3:1. Averaged over 1000 runs, I got this method at 1063ms, and the method below (straightforward byte by byte comparison) at 3031ms. Hashing always came back sub-second at around an average of 865ms. This testing was with an ~100MB video file.

Here's the ReadByte and hashing methods I used, for comparison purposes:

Part 1 of your question:

var allChecked = true;
$("input.abc").each(function(index, element){
  if(!element.checked){
    allChecked = false;
    return false;
  } 
});

EDIT:

The answer (http://stackoverflow.com/questions/5541387/check-if-all-checkboxes-are-selected/5541480#5541480) above is probably better.

I am fairly sure that Linq can do this.... but MyList does not have a select method on it (which is what I would have used).

Yes, LINQ can do this. It's simply:

MyList.Select(x => x.Name).ToArray();

Most likely the issue is that you either don't have a reference to System.Core, or you are missing an using directive for System.Linq.

you should not use Nested List in List.

List<List<T>> 

is not legal, even if T were a defined type.

https://msdn.microsoft.com/en-us/library/ms182144.aspx

One Liner (pure Java)

list.toString().replace(", ", ",").replaceAll("[\\[.\\]]", "");

If you follow the standard event pattern, then you can add an extension method to make the checking of event firing safer/easier. (i.e. the following code adds an extension method called SafeFire() which does the null check, as well as (obviously) copying the event into a separate variable to be safe from the usual null race-condition that can affect events.)

(Although I am in kind of two minds whether you should be using extension methods on null objects...)

public static class EventFirer
{
    public static void SafeFire<TEventArgs>(this EventHandler<TEventArgs> theEvent, object obj, TEventArgs theEventArgs)
        where TEventArgs : EventArgs
    {
        if (theEvent != null)
            theEvent(obj, theEventArgs);
    }
}

class MyEventArgs : EventArgs
{
    // Blah, blah, blah...
}

class UseSafeEventFirer
{
    event EventHandler<MyEventArgs> MyEvent;

    void DemoSafeFire()
    {
        MyEvent.SafeFire(this, new MyEventArgs());
    }

    static void Main(string[] args)
    {
        var x = new UseSafeEventFirer();

        Console.WriteLine("Null:");
        x.DemoSafeFire();

        Console.WriteLine();

        x.MyEvent += delegate { Console.WriteLine("Hello, World!"); };
        Console.WriteLine("Not null:");
        x.DemoSafeFire();
    }
}

SciPy has the function scipy.special.factorial (formerly scipy.misc.factorial)

>>> import math
>>> import scipy.special
>>> math.factorial(6)
720
>>> scipy.special.factorial(6)
array(720.0)

You can use both javascript methods repeat() and split() together.

" ".repeat(10).split(" ")

This code will create an array that has 10 item and each item is empty string.

const items = " ".repeat(10).split(" ")

document.getElementById("context").innerHTML = items.map((item, index) => index)

console.log("items: ", items)

<pre id="context">

</pre>

You're getting a linker error, so your extern is working (the compiler compiled a.c without a problem), but when it went to link the object files together at the end it couldn't resolve your extern -- void doSomething(int); wasn't actually found anywhere. Did you mess up the extern? Make sure there's actually a doSomething defined in b.c that takes an int and returns void, and make sure you remembered to include b.c in your file list (i.e. you're doing something like gcc a.c b.c, not just gcc a.c)

This can also happen if you have a naming policy around version, prohibiting the version# you are trying to deploy. In my case I was trying to upload a version (to release repo) 2.0.1 but later found out that our nexus configuration doesn't allow anything other than whole number for releases.

I tried later with version 2 and deployed it successfully.

The error message definitely dosen't help:

Return code is: 400, ReasonPhrase: Repository does not allow updating assets: maven-releases-xxx. -> [Help 1]

A better message could have been version 2.0.1 violates naming policy

Both methods do the same functionally - they compare values.
As is written on MSDN:

• About String.Equals method - Determines whether this instance and another specified String object have the same value. (http://msdn.microsoft.com/en-us/library/858x0yyx.aspx)
• About == - Although string is a reference type, the equality operators (== and !=) are defined to compare the values of string objects, not references. This makes testing for string equality more intuitive. (http://msdn.microsoft.com/en-en/library/362314fe.aspx)

But if one of your string instances is null, these methods are working differently:

string x = null;
string y = "qq";
if (x == y) // returns false
    MessageBox.Show("true");
else
    MessageBox.Show("false");

if (x.Equals(y)) // returns System.NullReferenceException: Object reference not set to an instance of an object. - because x is null !!!
    MessageBox.Show("true");
else
    MessageBox.Show("false");

In theory SMTP can be handled by either TCP, UDP, or some 3rd party protocol.

As defined in RFC 821, RFC 2821, and RFC 5321:

SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.

In addition, the Internet Assigned Numbers Authority has allocated port 25 for both TCP and UDP for use by SMTP.

In practice however, most if not all organizations and applications only choose to implement the TCP protocol. For example, in Microsoft's port listing port 25 is only listed for TCP and not UDP.

The big difference between TCP and UDP that makes TCP ideal here is that TCP checks to make sure that every packet is received and re-sends them if they are not whereas UDP will simply send packets and not check for receipt. This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.

Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered.

you forgot to add add alpha1 in module area

compile 'com.android.support:appcompat-v7:26.0.0-alpha1'

use maven repository in project area that's it

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

my_list = ['a', 'b', 'c', 'd']
my_string = ','.join(my_list)

'a,b,c,d'

This won't work if the list contains integers

And if the list contains non-string types (such as integers, floats, bools, None) then do:

my_string = ','.join(map(str, my_list)) 

It seems to me that the answer to this question is (at least now) clearly documented on the Safari HTML5 docs:

User Control of Downloads Over Cellular Networks

In Safari on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and autoplay are disabled. No data is loaded until the user initiates it. This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not.

This plays the movie: <input type="button" value="Play" onClick="document.myMovie.play()">

This does nothing on iOS: <body onLoad="document.myMovie.play()">

I refactored your code a bit and believe I came with the solution for which you were looking. Basically instead of setting searchIDs to be the result of the .map() I just pushed the values into an array.

$("#merge_button").click(function(event){
  event.preventDefault();

  var searchIDs = [];

  $("#find-table input:checkbox:checked").map(function(){
    searchIDs.push($(this).val());
  });

  console.log(searchIDs);
});

I created a fiddle with the code running.

You can implement this using Java 8 lambdas.

import java.util.HashMap;
import java.util.Map;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.event.Level;

public class LevelLogger {
    private static final Logger LOGGER = LoggerFactory.getLogger(LevelLogger.class);
    private static final Map<Level, LoggingFunction> map;

    static {
        map = new HashMap<>();
        map.put(Level.TRACE, (o) -> LOGGER.trace(o));
        map.put(Level.DEBUG, (o) -> LOGGER.debug(o));
        map.put(Level.INFO, (o) -> LOGGER.info(o));
        map.put(Level.WARN, (o) -> LOGGER.warn(o));
        map.put(Level.ERROR, (o) -> LOGGER.error(o));
    }

    public static void log(Level level, String s) {
        map.get(level).log(s);
    }

    @FunctionalInterface
    private interface LoggingFunction {
        public void log(String arg);
    }
}

If by the type of a variable you mean the runtime class of the object that the variable points to, then you can get this through the class reference that all objects have.

val name = "sam";
name: java.lang.String = sam
name.getClass
res0: java.lang.Class[_] = class java.lang.String

If you however mean the type that the variable was declared as, then you cannot get that. Eg, if you say

val name: Object = "sam"

then you will still get a String back from the above code.

Here's a simple hash function that I use for a hash table I built. Its basically for taking a text file and stores every word in an index which represents the alphabetical order.

int generatehashkey(const char *name)
{
        int x = tolower(name[0])- 97;
        if (x < 0 || x > 25)
           x = 26;
        return x;
}

What this basically does is words are hashed according to their first letter. So, word starting with 'a' would get a hash key of 0, 'b' would get 1 and so on and 'z' would be 25. Numbers and symbols would have a hash key of 26. THere is an advantage this provides; You can calculate easily and quickly where a given word would be indexed in the hash table since its all in an alphabetical order, something like this: Code can be found here: https://github.com/abhijitcpatil/general

Giving the following text as input: Atticus said to Jem one day, “I’d rather you shot at tin cans in the backyard, but I know you’ll go after birds. Shoot all the blue jays you want, if you can hit ‘em, but remember it’s a sin to kill a mockingbird.” That was the only time I ever heard Atticus say it was a sin to do something, and I asked Miss Maudie about it. “Your father’s right,” she said. “Mockingbirds don’t do one thing except make music for us to enjoy. They don’t eat up people’s gardens, don’t nest in corn cribs, they don’t do one thing but sing their hearts out for us. That’s why it’s a sin to kill a mockingbird.

This would be the output:

What I do usually after new installation is to modify the main css file where all visual styles are stored. I use Miniconda but location is similar with others C:\Miniconda3\Lib\site-packages\notebook\static\style\style.min.css

With some screens these resolutions are different and more than 1. To be on the safe side I change all to 98% so if I disconnect from my external screens on my laptop I still have 98% screen width.

Then just replace 1140px with 98% of the screen width.

@media (min-width: 1200px) {
  .container {
    width: 1140px;
  }
}

After editing

@media (min-width: 1200px) {
  .container {
    width: 98%;
  }
}

Save and restart your notebook

Update

Recently had to wider Jupyter cells on an environment it is installed, which led me to come back here and remind myself.

If you need to do it in virtual env you installed jupyter on. You can find the css file in this subdir

env/lib/python3.6/site-packages/notebook/static/style/stye.min.css

In the management studio diagram choose the table, right click to add new column if desired, right-click on the column and choose "Check Constraints", there you can add one.

Always safe to use either Comparator or Comparable interface to provide sorting implementation (if the object is not a String or Wrapper classes for primitive data types) . As an example for a comparator implementation to sort employees based on name

    List<Employees> empList = new LinkedList<Employees>(EmpSet);

    class EmployeeComparator implements Comparator<Employee> {

            public int compare(Employee e1, Employee e2) {
                return e1.getName().compareTo(e2.getName());
            }

        }

   Collections.sort(empList , new EmployeeComparator ());

Comparator is useful when you need to have different sorting algorithm on same object (Say emp name, emp salary, etc). Single mode sorting can be implemented by using Comparable interface in to the required object.

In my case, it was something else. One day earlier I tried to install wordpress using bitnam of xampp, but I was not successfull. When I saw the error log, there was an error :

httpd.exe: Syntax error on line 560 of C:/xampp/apache/conf/httpd.conf: Could not open configuration file C:/xampp/apps/wordpress/conf/httpd-prefix.conf: The system cannot find the path specified.

I opened the httpd.conf and found this line:

Include "C:/xampp/apps/wordpress/conf/httpd-prefix.conf"

I just commented it with #,

Now it's running fine. :)

Your second way is correct.

def foo(opts: dict = {}):
    pass

print(foo.__annotations__)

this outputs

{'opts': <class 'dict'>}

It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.

I strongly advise against using mutable keyword arguments. More information here.

I use DataBinding for this (with Kotlin).

Set up BindingAdapter:

BindingAdapter.kt

import android.graphics.Typeface
import android.view.View
import android.view.ViewGroup
import android.widget.TextView
import androidx.databinding.BindingAdapter
import java.util.*


object BindingAdapters {


    @JvmStatic
    @BindingAdapter("typeface", "typefaceStyle")
    fun setTypeface(v: TextView, tf: Typeface?, style: Int?) {
        v.setTypeface(tf ?: Typeface.DEFAULT, style ?: Typeface.NORMAL)
    }
}

Usage:

fragment_custom_view.xml

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <data>

        <import type="android.graphics.Typeface" />

        <variable
            name="typeface"
            type="android.graphics.Typeface" />

    </data>


    <TextView
        android:id="@+id/reference"
        style="@style/TextAppearance.MaterialComponents.Body1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="I'm formatted text"
        app:typeface="@{typeface}"
        app:typefaceStyle="@{Typeface.ITALIC}" />

</layout>

MyFragment.kt

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        binding = FragmentCustomView.bind(view)
        binding.typeface = // some code to get user selected typeface

}

Now, if the user selects a new typeface you can just update the binding value and all your TextViews that you've set app:typeface will get updated.

You can set min-width property of CSS for body tag. Since this property is not supported by IE6, you can write like:

body{
   min-width:1000px;        /* Suppose you want minimum width of 1000px */
   width: auto !important;  /* Firefox will set width as auto */
   width:1000px;            /* As IE6 ignores !important it will set width as 1000px; */
}

Or:

body{
   min-width:1000px; // Suppose you want minimum width of 1000px
   _width: expression( document.body.clientWidth > 1000 ? "1000px" : "auto" ); /* sets max-width for IE6 */
}

In the case of Java:

If we use DataFrames, while applying joins (here Inner join), we can sort (in ASC) after selecting distinct elements in each DF as:

Dataset<Row> d1 = e_data.distinct().join(s_data.distinct(), "e_id").orderBy("salary");

where e_id is the column on which join is applied while sorted by salary in ASC.

Also, we can use Spark SQL as:

SQLContext sqlCtx = spark.sqlContext();
sqlCtx.sql("select * from global_temp.salary order by salary desc").show();

where

• spark  -> SparkSession
• salary -> GlobalTemp View.

I have tried it hope it works for you

NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];      
int unitFlags =NSDayCalendarUnit;      
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];     
NSDate *myDate; //= [[NSDate alloc] init];     
[dateFormatter setDateFormat:@"dd-MM-yyyy"];   
myDate = [dateFormatter dateFromString:self.strPrevioisDate];     
NSDateComponents *comps = [gregorian components:unitFlags fromDate:myDate toDate:[NSDate date] options:0];   
NSInteger day=[comps day];

A less elegant way that will throw all the right error messages (based on Array.prototype.filter) but will stop iterating on the first result is

function findFirst(arr, test, context) {
    var Result = function (v, i) {this.value = v; this.index = i;};
    try {
        Array.prototype.filter.call(arr, function (v, i, a) {
            if (test(v, i, a)) throw new Result(v, i);
        }, context);
    } catch (e) {
        if (e instanceof Result) return e;
        throw e;
    }
}

Then examples are

findFirst([-2, -1, 0, 1, 2, 3], function (e) {return e > 1 && e % 2;});
// Result {value: 3, index: 5}
findFirst([0, 1, 2, 3], 0);               // bad function param
// TypeError: number is not a function
findFirst(0, function () {return true;}); // bad arr param
// undefined
findFirst([1], function (e) {return 0;}); // no match
// undefined

It works by ending filter by using throw.

Actually, in iOS development by react-native when I use display: 'none' or something like below:

const styles = StyleSheet.create({
  disappearImage: {
    width: 0,
    height: 0
  }
});

The iOS doesn't load anything else of the Image component like onLoad or etc, so I decided to use something like below:

const styles = StyleSheet.create({
  disappearImage: {
    width: 1,
    height: 1,
    position: 'absolute',
    top: -9000,
    opacity: 0
  }
});

You need to decide which directory you want the file to be relative to. Once you have done that, you construct the full path like this:

string fullPathToFile = Path.Combine(dir, fileName);

If you don't supply the base directory dir then you will be at the total mercy of whatever happens to the working directory of your process. That is something that can be out of your control. For example, shortcuts to your application may specify it. Using file dialogs can change it.

For a console application it is reasonable to use relative files directly because console applications are designed so that the working directory is a critical input and is a well-defined part of the execution environment. However, for a GUI app that is not the case which is why I recommend you explicitly convert your relative file name to a full absolute path using some well-defined base directory.

Now, since you have a console application, it is reasonable for you to use a relative path, provided that the expectation is that the files in question will be located in the working directory. But it would be very common for that not to be the case. Normally the working directory is used to specify where the user's input and output files are to be stored. It does not typically point to the location where the program's files are.

One final option is that you don't attempt to deploy these program files as external text files. Perhaps a better option is to link them to the executable as resources. That way they are bound up with the executable and you can completely side-step this issue.

This is not Bootstrap Standard to give col-md-1.5 and you can not edit bootstrap.min.css because is not right way. you can create like this http://www.bootply.com/125259

git add . && git commit -m "your message here"

You can add extra data with form data

use serializeArray and add the additional data:

var data = $('#myForm').serializeArray();
    data.push({name: 'tienn2t', value: 'love'});
    $.ajax({
      type: "POST",
      url: "your url.php",
      data: data,
      dataType: "json",
      success: function(data) {
          //var obj = jQuery.parseJSON(data); if the dataType is not     specified as json uncomment this
        // do what ever you want with the server response
     },
    error: function() {
        alert('error handing here');
    }
});

I created these functions for my website, I use only vanilla javascript, maybe it will help someone. First I created a function to get any HTML element:

//return an HTML element by ID, class or tag name
    var getElement = function(selector) {
        var elements = [];
        if(selector[0] == '#') {
            elements.push(document.getElementById(selector.substring(1, selector.length)));
        } else if(selector[0] == '.') {
            elements = document.getElementsByClassName(selector.substring(1, selector.length));
        } else {
            elements = document.getElementsByTagName(selector);
        }
        return elements;
    }

Then the function that recieve the class to remove and the selector of the element:

var hasClass = function(selector, _class) {
        var elements = getElement(selector);
        var contains = false;
        for (let index = 0; index < elements.length; index++) {
            const curElement = elements[index];
            if(curElement.classList.contains(_class)) {
                contains = true;
                break;
            }
        }
        return contains;
    }

Now you can use it like this:

hasClass('body', 'gray')
hasClass('#like', 'green')
hasClass('.button', 'active')

Hope it will help.

sudo apt-get install openjdk-11-jdk

after this, try

java -version

to make sure java version is 1.11.x, if found old one or different, check below command to see the available jdks,

sudo update-java-alternatives --list

you should see something like below,

java-1.11.0-openjdk-amd64 1111 /usr/lib/jvm/java-1.11.0-openjdk-amd64

java-1.8.0-openjdk-amd64 1081 /usr/lib/jvm/java-1.8.0-openjdk-amd64

you can see java 1.11 available from above list, use below command to set java 11 to default,

sudo update-alternatives --config java

for above command, you will get something like below and also, will ask for an option to set,

There are 3 choices for the alternative java (providing /usr/bin/java).

Selection Path Priority Status

---

0 /usr/lib/jvm/java-11-openjdk-amd64/bin/java 1111 auto mode

*2 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1081 manual mode

3 /usr/lib/jvm/jdk1.8.0_211/bin/java 0 manual mode

Press to keep the current choice[*], or type selection number:

you can select desired selection number, my case it's 0

for javac,

sudo update-alternatives --config javac

will result something like below,

There are 3 choices for the alternative javac (providing /usr/bin/javac).

Selection Path Priority Status

---

0 /usr/lib/jvm/java-11-openjdk-amd64/bin/javac 1111 auto mode

*2 /usr/lib/jvm/java-8-openjdk-amd64/bin/javac 1081 manual mode
3 /usr/lib/jvm/jdk1.8.0_211/bin/javac 0 manual mode

Press to keep the current choice[*], or type selection number:

in my case, it's 0 again

after above steps, try

java -version

it will display something like below,

It works for me , I hope it may use to other's also for Angular 4-5. :)

While this is sort of a follow up to the previous answer, it adds a little (hopefully).

Mainly what I want to clarify is that usually we think of drawing things like draw a rectangle at 10, 3.

So if we think about that like this: move origin to 10, 3, then draw rectangle at 0, 0. Then all we have to do is add a rotate in between.

Another big point is the alignment of the text. It's easiest to draw the text at 0, 0, so using the correct alignment can allow us to do that without measuring the text width.

We should still move the text by an amount to get it centered vertically, and unfortunately canvas does not have great line height support, so that's a guess and check thing ( correct me if there is something better ).

I've created 3 examples that provide a point and a text with 3 alignments, to show what the actual point on the screen is where the font will go.

var font, lineHeight, x, y;

x = 100;
y = 100;
font = 20;
lineHeight = 15; // this is guess and check as far as I know
this.context.font = font + 'px Arial';


// Right Aligned
this.context.save();
this.context.translate(x, y);
this.context.rotate(-Math.PI / 4);

this.context.textAlign = 'right';
this.context.fillText('right', 0, lineHeight / 2);

this.context.restore();

this.context.fillStyle = 'red';
this.context.fillRect(x, y, 2, 2);


// Center
this.context.fillStyle = 'black';
x = 150;
y = 100;

this.context.save();
this.context.translate(x, y);
this.context.rotate(-Math.PI / 4);

this.context.textAlign = 'center';
this.context.fillText('center', 0, lineHeight / 2);

this.context.restore();

this.context.fillStyle = 'red';
this.context.fillRect(x, y, 2, 2);


// Left
this.context.fillStyle = 'black';
x = 200;
y = 100;

this.context.save();
this.context.translate(x, y);
this.context.rotate(-Math.PI / 4);

this.context.textAlign = 'left';
this.context.fillText('left', 0, lineHeight / 2);

this.context.restore();

this.context.fillStyle = 'red';
this.context.fillRect(x, y, 2, 2);

The line this.context.fillText('right', 0, lineHeight / 2); is basically 0, 0, except we move slightly for the text to be centered near the point

1. Go to the official website and download the source code for the version you need

2. Then unzip the update package and execute the following command

   ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl  -Wl,-rpath,/usr/local/ssl/lib shared
   

Because the default is to generate only static libraries, if you want dynamic libraries, add the "shared" option

3. make && make install

My favorite approach, without external libraries:

try {
    URI uri = new URI(name);

    // perform checks for scheme, authority, host, etc., based on your requirements

    if ("mailto".equals(uri.getScheme()) {/*Code*/}
    if (uri.getHost() == null) {/*Code*/}

} catch (URISyntaxException e) {
}

You need to write your file to the request stream:

using (var reqStream = req.GetRequestStream()) 
{    
    reqStream.Write( ... ) // write the bytes of the file
}

I know the topic is old, but I just fell on it after a google search so... here is another solution:

$array_merged = array_merge($array_going_first, $array_going_second);

This one seems pretty clean to me, it works just fine!

You can replace the src/main/resources/ directly by classpath:

So for your example you will replace this line:

new BufferedReader(new FileReader(new File("src/main/resources/config.txt")));

By this line:

new BufferedReader(new FileReader(new File("classpath:config.txt")));

This is a working code

imageView.setDrawingCacheEnabled(true);
imageView.buildDrawingCache();
Bitmap bitmap = Bitmap.createBitmap(imageView.getDrawingCache());

$("option:selected").attr("selected", false);

Put the following into your ~/.Rprofile file:

exclude <-  function(blah) {
    "excluded block"
}

Now, you can exclude blocks like follows:

stuffiwant

exclude({
    stuffidontwant
    morestuffidontwant
})

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

You do want to avoid explicit loops as much as possible when doing array computing, as that reduces the speed gain from that form of computing. There are multiple ways to initialize a numpy array. If you want it filled with zeros, do as katrielalex said:

big_array = numpy.zeros((10,4))

EDIT: What sort of sequence is it you're making? You should check out the different numpy functions that create arrays, like numpy.linspace(start, stop, size) (equally spaced number), or numpy.arange(start, stop, inc). Where possible, these functions will make arrays substantially faster than doing the same work in explicit loops

Apparently this is a known bug of Eclipse. This bug is resolved with the resolution of WONT-FIX. I have no idea why though. here is the link: Eclipse C Console Bug.

Create New File in Specified Path

import java.io.File;
import java.io.IOException;

public class CreateNewFile {

    public static void main(String[] args) {
        try {
            File file = new File("d:/sampleFile.txt");
            if(file.createNewFile())
                System.out.println("File creation successfull");
            else
                System.out.println("Error while creating File, file already exists in specified path");
        }
        catch(IOException io) {
            io.printStackTrace();
        }
    }

}

Program Output:

Using symfony 2.3 with php 5.5 and using the built in server with

app/console server:run

which should output something like:

Server running on http://127.0.0.1:8000
Quit the server with CONTROL-C.

then go to http://127.0.0.1:8000/app_dev.php/app/example

this should give you the default, which you can also find the default route by viewing src/AppBundle/Controller/DefaultController.php

No root is required:

This code will get 3rd party packages path with the name so you can easily identify your APK

adb shell pm list packages -f -3

the output will be

package:/data/app/XX.XX.XX.apk=YY.YY.YY

now pull that package using below code:

adb pull /data/app/XX.XX.XX.apk

if you executed above cmd in C:>\ , then you will find that package there.

I would like to run an automation test in different environments.
So I add this to command maven command:

spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=productionEnv1"

Here is the link where I found the solution: [1]https://github.com/spring-projects/spring-boot/issues/1095

In my case, Incorrect string value: '\xCC\x88'..., the problem was that an o-umlaut was in its decomposed state. This question-and-answer helped me understand the difference between o¨ and ö. In PHP, the fix for me was to use PHP's Normalizer library. E.g., Normalizer::normalize('o¨', Normalizer::FORM_C).

One main reason we went with Workstation over Player at my job is because we need to run VMs that use a physical disk as their hard drive instead of a virtual disk. Workstation supports using physical disks while Player does not.

It is OK, but at the same time can cause some browsers to become slow.

My advice is use <a href="#"></a>

If you're using JQuery remember to also use:

.click(function(event){
    event.preventDefault();
    // Click code here...
});

data.Select(x=>x.Name).Distinct().Select(x => new SelectListItem { Text = x });

Last time I checked, Java is not capable of natively doing what you want; you have to use 'work-arounds' to get around such limitations. As far as I see it, interfaces ARE an alternative, but not a good alternative. Perhaps whoever told you that was meaning something like this:

public interface ComponentMethod {
  public abstract void PerfromMethod(Container c);
}

public class ChangeColor implements ComponentMethod {
  @Override
  public void PerfromMethod(Container c) {
    // do color change stuff
  }
}

public class ChangeSize implements ComponentMethod {
  @Override
  public void PerfromMethod(Container c) {
    // do color change stuff
  }
}

public void setAllComponents(Component[] myComponentArray, ComponentMethod myMethod) {
    for (Component leaf : myComponentArray) {
        if (leaf instanceof Container) { //recursive call if Container
            Container node = (Container) leaf;
            setAllComponents(node.getComponents(), myMethod);
        } //end if node
        myMethod.PerfromMethod(leaf);
    } //end looping through components
}

Which you'd then invoke with:

setAllComponents(this.getComponents(), new ChangeColor());
setAllComponents(this.getComponents(), new ChangeSize());

Why not use the Bootstrap predefined class input-block-level that does the job?

<a href="#" class="btn input-block-level">Full-Width Button</a> <!-- BS2 -->
<a href="#" class="btn form-control">Full-Width Button</a> <!-- BS3 -->

<!-- And let's join both for BS# :) -->
<a href="#" class="btn input-block-level form-control">Full-Width Button</a>

I was facing the same problem, using gradle and it got solved on adding following dependencies-

compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-web')
testCompile('org.springframework.boot:spring-boot-starter-test')
compile('org.apache.tomcat.embed:tomcat-embed-jasper')

earlier I was missing the last one causing the same error.

Change this.foo() to module.exports.foo()

If you'd like to turn this on by default for ALL ObjectMapper instances in a process, here's a little hack that will set the default value of INDENT_OUTPUT to true:

val indentOutput = SerializationFeature.INDENT_OUTPUT
val defaultStateField = indentOutput.getClass.getDeclaredField("_defaultState")
defaultStateField.setAccessible(true)
defaultStateField.set(indentOutput, true)

Try File > New > Project... > Android Project From Existing Code. Don't copy your project from pc into workspace, copy it elsewhere and let the eclipse copy it into workspace by menu commands above and checking copy in existing workspace.

    String res = result.getResponseAsString();//{"status":"true","msg":"success"}
    loginValidator = objectMapper.readValue(res, StatusResponses.class);//replaced result.getResponseAsString() with res
} catch (Exception e) {

}

Don't know how it worked and why it worked? :( but it worked

Per Mozilla's Map documentation, you can initialize as follows:

private _gridOptions:Map<string, Array<string>> = 
    new Map([
        ["1", ["test"]],
        ["2", ["test2"]]
    ]);

Use the Nix package manager!

Install Nix, and then do nix-env -iA nixpkgs.watch and it should be available for use after the completing the install instructions (including sourcing . "$HOME/.nix-profile/etc/profile.d/nix.sh" in your shell).

In my case, it was very slow and i needed to change inspections settings, i tried everything, the only thing that worked was going from 2018.2 version to 2016.2, sometimes is better to be some updates behind...

A common case for simply setting -fpermissive and not sweating it exists: the thoroughly-tested and working third-party library that won't compile on newer compiler versions without -fpermissive. These libraries exist, and are very likely not the application developer's problem to solve, nor in the developer's schedule budget to do it.

Set -fpermissive and move on in that case.

From SQL Server you can set a Unique key index on the table for (Columns that needs to be unique)

This one Works for me with asp label control.

         } 
     }

The gitlab has a lot of tokens:

• Private token
• Personal Access Token
• CI/CD running token

I tested only the Personal Access Token using GitLab Community Edition 10.1.2, the example:

git clone https://gitlab-ci-token:${Personal Access Tokens}@gitlab.com/username/myrepo.git


git clone https://oauth2:${Personal Access Tokens}@gitlab.com/username/myrepo.git

or using username and password:

git clone https://${username}:${password}@gitlab.com/username/myrepo.git

or by input your password:

git clone https://${username}@gitlab.com/username/myrepo.git

But the private token seems can not work.

In a Spring Boot 2 application you can either exclude the service configuration from autoconfiguration:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.servlet.UserDetailsServiceAutoConfiguration

or if you just want to hide the message in the logs you can simply change the log level:

logging.level.org.springframework.boot.autoconfigure.security=WARN

Further information can be found here: https://docs.spring.io/spring-boot/docs/2.0.x/reference/html/boot-features-security.html

Simple jQuery, PHP and JSONP example is below:

  success: function(data){_x000D_
   console.log('data', data)_x000D_
  },_x000D_

If you have Scala installed, here's a one-liner to shuffle the input:

ls -1 | scala -e 'for (l <- util.Random.shuffle(io.Source.stdin.getLines.toList)) println(l)'

Also simple and easy:

Start-Sleep 10

the equivalent to the batch program would be

#include<iostream>
int main()
{
    std::cout<<"Hello, World!\n";
    std::cin.get();
    return 0;
}

The additional line does exactly what PAUSE does, waits for a single character input

The answer to the question is scattered around in the comments under the already given answers. So, I am just summarising and simplifying here.

Option1: Protocols

If you want to create an abstract class with no implementation use 'Protocols'. The classes inheriting a protocol are obliged to implement the methods in the protocol.

@protocol ProtocolName
// list of methods and properties
@end

Option2: Template Method Pattern

If you want to create an abstract class with partial implementation like "Template Method Pattern" then this is the solution. Objective-C - Template methods pattern?

div hover background color change

I had an old libPod.a file specified (probably caused by me changing targets).

Project Settings -> Build Phases -> Link Binary with Libraries

Usually, cocoapods would only include one library, such as libPods-target.a or libPods.a. I solved it by removing the duplicate.

You want this - enter N and then take N number of elements.I am considering your input case is just like this

5
2 3 6 6 5

have this in this way in python 3.x (for python 2.x use raw_input() instead if input())

Python 3

n = int(input())
arr = input()   # takes the whole line of n numbers
l = list(map(int,arr.split(' '))) # split those numbers with space( becomes ['2','3','6','6','5']) and then map every element into int (becomes [2,3,6,6,5])

Python 2

n = int(raw_input())
arr = raw_input()   # takes the whole line of n numbers
l = list(map(int,arr.split(' '))) # split those numbers with space( becomes ['2','3','6','6','5']) and then map every element into int (becomes [2,3,6,6,5])

You could created sorted list from Values and rebuild the dictionary:

myDictionary={"two":"2", "one":"1", "five":"5", "1four":"4"}

newDictionary={}

sortedList=sorted(myDictionary.values())

for sortedKey in sortedList:
    for key, value in myDictionary.items():
        if value==sortedKey:
            newDictionary[key]=value

Output: newDictionary={'one': '1', 'two': '2', '1four': '4', 'five': '5'}

A bit late, but you can easily find a string with this query

    CLOSE columns_cur

DEALLOCATE columns_cur

END

CLOSE tables_cur
DEALLOCATE tables_cur

I would like to emphasize an answer that was in the comments that is working well for me. As mikey has said, this will work if you want to have variables in the included file in scope in the caller of 'include', just insert it as normal python. It works like an include statement in PHP. Works in Python 3.8.5. Happy coding!

Alternative #1

Alternative #2

with open('myfile.py') as f: exec(f.read())

Unfortunatelly, for IIS installed on Windows 7/8 machines, there is no option to create users only for IIS authentification. For Windows Server there is that option where you can add users from IIS Manager UI. These users have roles only on IIS, but not for the rest of the system. In this article it shows how you add users, but it is incorrect stating that is also appliable to standard OS, it only applies to server versions.

In your code:

while(fscanf(fp,"%s %c",item,&status) == 1)  

why 1 and not 2? The scanf functions return the number of objects read.

A date-time object is supposed to store the information about the date, time, timezone etc., not about the formatting. You can format a date-time object into a String with the pattern of your choice using date-time formatting API.

• The date-time formatting API for the modern date-time types is in the package, java.time.format e.g. java.time.format.DateTimeFormatter, java.time.format.DateTimeFormatterBuilder etc.
• The date-time formatting API for the legacy date-time types is in the package, java.text e.g. java.text.SimpleDateFormat, java.text.DateFormat etc.

Demo using modern API:

import java.time.LocalDate;
import java.time.Month;
import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Locale;

public class Main {
    public static void main(String[] args) {
        ZonedDateTime zdt = ZonedDateTime.of(LocalDate.of(2012, Month.DECEMBER, 1).atStartOfDay(),
                ZoneId.of("Europe/London"));

        // Default format returned by Date#toString
        System.out.println(zdt);

        // Custom format
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd", Locale.ENGLISH);
        String formattedDate = dtf.format(zdt);
        System.out.println(formattedDate);
    }
}

Output:

2012-12-01T00:00Z[Europe/London]
2012-12-01

Learn about the modern date-time API from Trail: Date Time.

Demo using legacy API:

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
import java.util.TimeZone;

public class Main {
    public static void main(String[] args) {
        Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        calendar.setTimeInMillis(0);
        calendar.set(Calendar.YEAR, 2012);
        calendar.set(Calendar.MONTH, 11);
        calendar.set(Calendar.DAY_OF_MONTH, 1);
        Date date = calendar.getTime();

        // Default format returned by Date#toString
        System.out.println(date);

        // Custom format
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
        String formattedDate = sdf.format(date);
        System.out.println(formattedDate);
    }
}

Output:

Some more important points:

1. The java.util.Date object is not a real date-time object like the modern date-time types; rather, it represents the milliseconds from the Epoch of January 1, 1970. When you print an object of java.util.Date, its toString method returns the date-time calculated from this milliseconds value. Since java.util.Date does not have timezone information, it applies the timezone of your JVM and displays the same. If you need to print the date-time in a different timezone, you will need to set the timezone to SimpleDateFomrat and obtain the formatted string from it.
2. The date-time API of java.util and their formatting API, SimpleDateFormat are outdated and error-prone. It is recommended to stop using them completely and switch to the modern date-time API.
   • For any reason, if you have to stick to Java 6 or Java 7, you can use ThreeTen-Backport which backports most of the java.time functionality to Java 6 & 7.
   • If you are working for an Android project and your Android API level is still not compliant with Java-8, check Java 8+ APIs available through desugaring and How to use ThreeTenABP in Android Project.

16kb is about right; if you're using gigabit ethernet, each packet could be 9kb in size.

if (!string.IsNullOrEmpty(Request.Form["username"])) { ... }

username is the name of the input on the submitting page. The password can be obtained the same way. If its not null or empty, it exists, then log in the user (I don't recall the exact steps for ASP.NET Membership, assuming that's what you're using).

I had this problem occasionally when using a multi-label name ie test.internal

The solution for me was to stop/start the dnscache on my windows 7 machine. Open a console as administrator and type

net stop dnscache
net start dnscache

then sigh and look for a way to get a Mac as your principal desktop.

In my case.I was getting missing element error pointing to NuGet.Config file. At that time it was looking some thing like this

<?xml version="1.0" encoding="utf-8"?>
<settings>
  <repositoryPath>Packages</repositoryPath>
</settings>

then I just added configuration tag that actually wraps entire xml. Now working fine for me

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <settings>
     <repositoryPath>Packages</repositoryPath>
  </settings>
</configuration>

In case of NULL columns it is better to use IF clause like this which combine the two functions of : CONCAT and COALESCE and uses special chars between the columns in result like space or '_'

SELECT FirstName , LastName , 
IF(FirstName IS NULL AND LastName IS NULL, NULL,' _ ',CONCAT(COALESCE(FirstName ,''), COALESCE(LastName ,''))) 
AS Contact_Phone FROM   TABLE1

.p12 and .pfx are both PKCS #12 files. Am I missing something?

Have you tried renaming the exported .pfx file to have a .p12 extension?

Raymond Chen has a few ideas:

https://devblogs.microsoft.com/oldnewthing/20050128-00/?p=36573

Quoted here in full because MSDN archives tend to be somewhat unreliable:

The easy way is to use the %CD% pseudo-variable. It expands to the current working directory.

set OLDDIR=%CD%
.. do stuff ..
chdir /d %OLDDIR% &rem restore current directory

(Of course, directory save/restore could more easily have been done with pushd/popd, but that's not the point here.)

The %CD% trick is handy even from the command line. For example, I often find myself in a directory where there's a file that I want to operate on but... oh, I need to chdir to some other directory in order to perform that operation.

set _=%CD%\curfile.txt
cd ... some other directory ...
somecommand args %_% args

(I like to use %_% as my scratch environment variable.)

Type SET /? to see the other pseudo-variables provided by the command processor.

Also the comments in the article are well worth scanning for example this one (via the WayBack Machine, since comments are gone from older articles):

This covers the use of %~dp0:

If you want to know where the batch file lives: %~dp0

%0 is the name of the batch file. ~dp gives you the drive and path of the specified argument.

You can try this. Function below sets all values of object's properties to undefined. Works as well with nested objects.

var clearObjectValues = (objToClear) => {
    Object.keys(objToClear).forEach((param) => {
        if ( (objToClear[param]).toString() === "[object Object]" ) {
            clearObjectValues(objToClear[param]);
        } else {
            objToClear[param] = undefined;
        }
    })
    return objToClear;
};

Found the solution:

I was uploading the build, Every activity went well except “Authenticating with the iTunes store”.

I disconnected my LAN cable and Connected my MAC with my mobile hotspot. and authentication problem was solved. If you have a limited internet plan then as soon as you pass authentication stage, again connect your LAN so that it will upload the app from you LAN cable's internet connection.

More accurately anything that is not 0 is true.

So 1 is true, but so is 2, 3 ... etc.

Your link is not a playlist.

A proper playlist URL looks like this:

https://www.youtube.com/playlist?list=PLHSdFJ8BDqEyvUUzm6R0HxawSWniP2c9K

Your URL is just the first video OF a certain playlist. It contains https://www.youtube.com/watch? instead of https://www.youtube.com/playlist?.

Pick the playlist by clicking on the title of the playlist on the right side in the list of videos and use this URL.

The node-mysql library automatically performs escaping when used as you are already doing. See https://github.com/felixge/node-mysql#escaping-query-values

My error was that I left a space in between localhost: and the port.

If you're using ASP.NET 2.0 or greater, you can turn it on in the Web.config file. In the <system.web> section, add the following line:

<httpCookies httpOnlyCookies="true"/>

Below is a batch file that will wait for 1 minute, check the day, and then perform an action. It uses PING.EXE, but requires no files that aren't included with Windows.

@ECHO OFF

:LOOP
ECHO Waiting for 1 minute...
  PING -n 60 127.0.0.1>nul
  IF %DATE:~0,3%==Mon CALL SomeOtherFile.cmd
  IF %DATE:~0,3%==Tue CALL SomeOtherFile.cmd
  IF %DATE:~0,3%==Wed CALL SomeOtherFile.cmd
  IF %DATE:~0,3%==Thu CALL WootSomeOtherFile.cmd
  IF %DATE:~0,3%==Fri CALL SomeOtherFile.cmd
  IF %DATE:~0,3%==Sat ECHO Saturday...nothing to do.
  IF %DATE:~0,3%==Sun ECHO Sunday...nothing to do.
GOTO LOOP

It could be improved upon in many ways, but it might get you started.

Bear in mind that 0 is a special case of parameter numbers inside a batch file, where 0 means this file as given on the command line.

So if the file is myfile.bat, you could call it in several ways as follows, each of which would give you a different output from the %0 or %~0 usage:

myfile

myfile.bat

mydir\myfile.bat

c:\mydir\myfile.bat

"c:\mydir\myfile.bat"

All of the above are legal calls if you call it from the correct relative place to the directory in which it exists. %~0 strips the quotes from the last example, whereas %0 does not.

Because these all give different results, %0 and %~0 are very unlikely to be what you actually want to use.

Here's a batch file to illustrate:

@echo Full path and filename: %~f0
@echo Drive: %~d0
@echo Path: %~p0
@echo Drive and path: %~dp0
@echo Filename without extension: %~n0
@echo Filename with    extension: %~nx0
@echo Extension: %~x0
@echo Filename as given on command line: %0
@echo Filename as given on command line minus quotes: %~0
@REM Build from parts

Compilating answers here and there, here's a complete set of arr tools to get the work done:

Function getArraySize(arr As Variant)
' returns array size for a n dimention array
' usage result(k) = size of the k-th dimension

Dim ndims As Long
Dim arrsize() As Variant
ndims = getDimensions(arr)
ReDim arrsize(ndims - 1)
For i = 1 To ndims
    arrsize(i - 1) = getDimSize(arr, i)
Next i
getArraySize = arrsize
End Function

Function getDimSize(arr As Variant, dimension As Integer)
' returns size for the given dimension number
    getDimSize = UBound(arr, dimension) - LBound(arr, dimension) + 1
End Function

Function getDimensions(arr As Variant) As Long
' returns number of dimension in an array (ex. sheet range = 2 dimensions)
    On Error GoTo Err
    Dim i As Long
    Dim tmp As Long
    i = 0
    Do While True
        i = i + 1
        tmp = UBound(arr, i)
    Loop
Err:
    getDimensions = i - 1
End Function

I understand that its been answered already. but I hope this will help someone in future and saves so much time and pain.

PHP code on how I'm returning data to this jquery ajax call in autocomplete:

You can use this javascript code to redirect after a specific time. Hope it will work.

setRedirectTime(function () 
{
   window.location.href= 'https://www.google.com'; // the redirect URL will be here

},10000); // 10 seconds

I had the same problem, running Mountain Lion with Ruby 2 installed and used instead of system ruby.

Previously I added PATH=/usr/local/bin:$PATH to my ~/.bash_profile as a way to make sure stuff installed by homebrew, including Ruby 2, took precedence over system-installed binaries.

Anyway, in this case I noticed that cocoapods would install their 'pod' binary not in /usr/local/bin but rather in /usr/local/Cellar/ruby/2.0.0-p247/bin/

So to my .bash_profile I added PATH=$PATH:/usr/local/Cellar/ruby/2.0.0-p247/bin/ and now cocoapods is working like a charm.

importing col, when from pyspark.sql.functions and updating fifth column to integer(0,1,2) based on the string(string a, string b, string c) into a new DataFrame.

from pyspark.sql.functions import col, when 

data_frame_temp = data_frame.withColumn("col_5",when(col("col_5") == "string a", 0).when(col("col_5") == "string b", 1).otherwise(2))

Silly workaround that always works.

$state.go("otherState").then(function(){
     $state.go("wantedState")
});

Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error() and curl_errno() will contain further information in case of failure:

try {
    $ch = curl_init();

    // Check if initialization had gone wrong*    
    if ($ch === false) {
        throw new Exception('failed to initialize');
    }

    curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt(/* ... */);

    $content = curl_exec($ch);

    // Check the return value of curl_exec(), too
    if ($content === false) {
        throw new Exception(curl_error($ch), curl_errno($ch));
    }

    /* Process $content here */

    // Close curl handle
    curl_close($ch);
} catch(Exception $e) {

    trigger_error(sprintf(
        'Curl failed with error #%d: %s',
        $e->getCode(), $e->getMessage()),
        E_USER_ERROR);

}

^* The curl_init() manual states:

Returns a cURL handle on success, FALSE on errors.

I've observed the function to return FALSE when you're using its $url parameter and the domain could not be resolved. If the parameter is unused, the function might never return FALSE. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.

No, this isn't possible. In order for you to send messages of any kind to a Facebook user, you need that user's permission to do so.

If someone logs into your site with Facebook Connect, they are explicitly agreeing to share their Facebook data with your site, and you will then be able to send that person a message through the normal channels. You would also be able to fetch their friend list. However, you can not send messages to the friends.

Here is a solution using the Shapely library. Shapely is often used for GIS work, but is built to be useful for computational geometry. I changed your inputs from lists to tuples.

Problem

# Given these endpoints
#line 1
A = (X, Y)
B = (X, Y)

#line 2
C = (X, Y)
D = (X, Y)

# Compute this:
point_of_intersection = (X, Y)

Solution

import shapely
from shapely.geometry import LineString, Point

line1 = LineString([A, B])
line2 = LineString([C, D])

int_pt = line1.intersection(line2)
point_of_intersection = int_pt.x, int_pt.y

print(point_of_intersection)

Got this working with .Net Core 3.1 as follows

1.Make sure you place the UseCors code between app.UseRouting(); and app.UseAuthentication();

        app.UseHttpsRedirection();

        app.UseRouting();
        app.UseCors("CorsApi");

        app.UseAuthentication();
        app.UseAuthorization();

        app.UseEndpoints(endpoints => {
            endpoints.MapControllers();
        });

2.Then place this code in the ConfigureServices method

services.AddCors(options =>
        {
            options.AddPolicy("CorsApi",
                builder => builder.WithOrigins("http://localhost:4200", "http://mywebsite.com")
            .AllowAnyHeader()
            .AllowAnyMethod());
        });

3.And above the base controller I placed this

[EnableCors("CorsApi")]
[Route("api/[controller]")]
[ApiController]
public class BaseController : ControllerBase

Now all my controllers will inherit from the BaseController and will have CORS enabled

git checkout foo/bar.txt

did you tried that? (without a HEAD keyword)

I usually revert my changes this way.

I found that AlertifyJS is a better alternative and have a Bootstrap theme.

alertify.alert('Alert Title', 'Alert Message!', function(){ alertify.success('Ok'); });

Also have a 4 components: Alert, Confirm, Prompt and Notifier.

Exmaple: JSFiddle

(DateTime.Parse((Eval("date").ToString()))).DayOfWeek.ToString()

at the place of Eval("date"),you can use any date...get name of day

Here's what I had to do to setup basic auth on Ubuntu 14.04 (didn't find a guide anywhere else)

Basic squid conf

/etc/squid3/squid.conf instead of the super bloated default config file

auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

# Choose the port you want. Below we set it to default 3128.
http_port 3128

Please note the basic_ncsa_auth program instead of the old ncsa_auth

squid 2.x

For squid 2.x you need to edit /etc/squid/squid.conf file and place:

auth_param basic program /usr/lib/squid/digest_pw_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Setting up a user

sudo htpasswd -c /etc/squid3/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid3 restart

squid 2.x

sudo htpasswd -c /etc/squid/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid restart

htdigest vs htpasswd

For the many people that asked me: the 2 tools produce different file formats:

• htdigest stores the password in plain text.
• htpasswd stores the password hashed (various hashing algos are available)

Despite this difference in format basic_ncsa_auth will still be able to parse a password file generated with htdigest. Hence you can alternatively use:

sudo htdigest -c /etc/squid3/passwords realm_you_like username_you_like

Beware that this approach is empirical, undocumented and may not be supported by future versions of Squid.

On Ubuntu 14.04 htdigest and htpasswd are both available in the [apache2-utils][1] package.

MacOS

Similar as above applies, but file paths are different.

Install squid

brew install squid

Start squid service

brew services start squid

Squid config file is stored at /usr/local/etc/squid.conf.

Comment or remove following line:

http_access allow localnet

Then similar to linux config (but with updated paths) add this:

auth_param basic program /usr/local/Cellar/squid/4.8/libexec/basic_ncsa_auth /usr/local/etc/squid_passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Note that path to basic_ncsa_auth may be different since it depends on installed version when using brew, you can verify this with ls /usr/local/Cellar/squid/. Also note that you should add the above just bellow the following section:

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

Now generate yourself a user:password basic auth credential (note: htpasswd and htdigest are also both available on MacOS)

htpasswd -c /usr/local/etc/squid_passwords username_you_like

Restart the squid service

brew services restart squid

Clear is faster because it does not loop over elements to delete. This method can assume that ALL elements can be deleted.

Remove all does not necessarily mean delete all elements in the list, only those provided as parameters SHOULD be delete. Hence, more effort is required to keep those which should not be deleted.

CLARIFICATION

By 'loop', I mean it does not have to check whether the element should be kept or not. It can set the reference to null without searching through the provided lists of elements to delete.

Clear IS faster than deleteall.

The import allows the java programmer to access classes of a package without package qualification.

The static import feature allows to access the static members of a class without the class qualification.

The import provides accessibility to classes and interface whereas static import provides accessibility to static members of the class.

Example :

With import

import java.lang.System.*;    
class StaticImportExample{  
    public static void main(String args[]){  

       System.out.println("Hello");
       System.out.println("Java");  

  }   
} 

With static import

import static java.lang.System.*;    
class StaticImportExample{  
  public static void main(String args[]){  

   out.println("Hello");//Now no need of System.out  
   out.println("Java");  

 }   
} 

See also : What is static import in Java 5

My two cents, adding trim to remove the initial whitespaces left in sAc's answer.

var str = 'Hello, World, etc';
var str_array = str.split(',');

for(var i = 0; i < str_array.length; i++) {
   // Trim the excess whitespace.
   str_array[i] = str_array[i].replace(/^\s*/, "").replace(/\s*$/, "");
   // Add additional code here, such as:
   alert(str_array[i]);
}

Edit:

After getting several upvotes on this answer, I wanted to revisit this. If you want to split on comma, and perform a trim operation, you can do it in one method call without any explicit loops due to the fact that split will also take a regular expression as an argument:

'Hello, cruel , world!'.split(/\s*,\s*/);
//-> ["Hello", "cruel", "world!"]

This solution, however, will not trim the beginning of the first item and the end of the last item which is typically not an issue.

And so to answer the question in regards to process in a loop, if your target browsers support ES5 array extras such as the map or forEach methods, then you could just simply do the following:

myStringWithCommas.split(/\s*,\s*/).forEach(function(myString) {
    console.log(myString);
});

NSTimeInterval seconds; // assume this exists
NSDate* ts_utc = [NSDate dateWithTimeIntervalSince1970:seconds];

NSDateFormatter* df_utc = [[[NSDateFormatter alloc] init] autorelease];
[df_utc setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
[df_utc setDateFormat:@"yyyy.MM.dd G 'at' HH:mm:ss zzz"];

NSDateFormatter* df_local = [[[NSDateFormatter alloc] init] autorelease];
[df_local setTimeZone:[NSTimeZone timeZoneWithName:@"EST"]];
[df_local setDateFormat:@"yyyy.MM.dd G 'at' HH:mm:ss zzz"];

NSString* ts_utc_string = [df_utc stringFromDate:ts_utc];
NSString* ts_local_string = [df_local stringFromDate:ts_utc];

// you can also use NSDateFormatter dateFromString to go the opposite way

Deleting duplicate rows in MySQL in-place, (Assuming you have a timestamp col to sort by) walkthrough:

Create the table and insert some rows:

create table penguins(foo int, bar varchar(15), baz datetime);
insert into penguins values(1, 'skipper', now());
insert into penguins values(1, 'skipper', now());
insert into penguins values(3, 'kowalski', now());
insert into penguins values(3, 'kowalski', now());
insert into penguins values(3, 'kowalski', now());
insert into penguins values(4, 'rico', now());
select * from penguins;
    +------+----------+---------------------+
    | foo  | bar      | baz                 |
    +------+----------+---------------------+
    |    1 | skipper  | 2014-08-25 14:21:54 |
    |    1 | skipper  | 2014-08-25 14:21:59 |
    |    3 | kowalski | 2014-08-25 14:22:09 |
    |    3 | kowalski | 2014-08-25 14:22:13 |
    |    3 | kowalski | 2014-08-25 14:22:15 |
    |    4 | rico     | 2014-08-25 14:22:22 |
    +------+----------+---------------------+
6 rows in set (0.00 sec)

Remove the duplicates in place:

delete a
    from penguins a
    left join(
    select max(baz) maxtimestamp, foo, bar
    from penguins
    group by foo, bar) b
    on a.baz = maxtimestamp and
    a.foo = b.foo and
    a.bar = b.bar
    where b.maxtimestamp IS NULL;
Query OK, 3 rows affected (0.01 sec)
select * from penguins;
+------+----------+---------------------+
| foo  | bar      | baz                 |
+------+----------+---------------------+
|    1 | skipper  | 2014-08-25 14:21:59 |
|    3 | kowalski | 2014-08-25 14:22:15 |
|    4 | rico     | 2014-08-25 14:22:22 |
+------+----------+---------------------+
3 rows in set (0.00 sec)

You're done, duplicate rows are removed, last one by timestamp is kept.

For those of you without a timestamp or unique column.

You don't have a timestamp or a unique index column to sort by? You're living in a state of degeneracy. You'll have to do additional steps to delete duplicate rows.

create the penguins table and add some rows

create table penguins(foo int, bar varchar(15)); 
insert into penguins values(1, 'skipper'); 
insert into penguins values(1, 'skipper'); 
insert into penguins values(3, 'kowalski'); 
insert into penguins values(3, 'kowalski'); 
insert into penguins values(3, 'kowalski'); 
insert into penguins values(4, 'rico'); 
select * from penguins; 
    # +------+----------+ 
    # | foo  | bar      | 
    # +------+----------+ 
    # |    1 | skipper  | 
    # |    1 | skipper  | 
    # |    3 | kowalski | 
    # |    3 | kowalski | 
    # |    3 | kowalski | 
    # |    4 | rico     | 
    # +------+----------+ 

make a clone of the first table and copy into it.

drop table if exists penguins_copy; 
create table penguins_copy as ( SELECT foo, bar FROM penguins );  

#add an autoincrementing primary key: 
ALTER TABLE penguins_copy ADD moo int AUTO_INCREMENT PRIMARY KEY first; 

select * from penguins_copy; 
    # +-----+------+----------+ 
    # | moo | foo  | bar      | 
    # +-----+------+----------+ 
    # |   1 |    1 | skipper  | 
    # |   2 |    1 | skipper  | 
    # |   3 |    3 | kowalski | 
    # |   4 |    3 | kowalski | 
    # |   5 |    3 | kowalski | 
    # |   6 |    4 | rico     | 
    # +-----+------+----------+ 

The max aggregate operates upon the new moo index:

delete a from penguins_copy a left join( 
    select max(moo) myindex, foo, bar 
    from penguins_copy 
    group by foo, bar) b 
    on a.moo = b.myindex and 
    a.foo = b.foo and 
    a.bar = b.bar 
    where b.myindex IS NULL; 

#drop the extra column on the copied table 
alter table penguins_copy drop moo; 
select * from penguins_copy; 

#drop the first table and put the copy table back: 
drop table penguins; 
create table penguins select * from penguins_copy; 

observe and cleanup

drop table penguins_copy; 
select * from penguins;
+------+----------+ 
| foo  | bar      | 
+------+----------+ 
|    1 | skipper  | 
|    3 | kowalski | 
|    4 | rico     | 
+------+----------+ 
    Elapsed: 1458.359 milliseconds 

What's that big SQL delete statement doing?

Table penguins with alias 'a' is left joined on a subset of table penguins called alias 'b'. The right hand table 'b' which is a subset finds the max timestamp [ or max moo ] grouped by columns foo and bar. This is matched to left hand table 'a'. (foo,bar,baz) on left has every row in the table. The right hand subset 'b' has a (maxtimestamp,foo,bar) which is matched to left only on the one that IS the max.

Every row that is not that max has value maxtimestamp of NULL. Filter down on those NULL rows and you have a set of all rows grouped by foo and bar that isn't the latest timestamp baz. Delete those ones.

Make a backup of the table before you run this.

Prevent this problem from ever happening again on this table:

If you got this to work, and it put out your "duplicate row" fire. Great. Now define a new composite unique key on your table (on those two columns) to prevent more duplicates from being added in the first place.

Like a good immune system, the bad rows shouldn't even be allowed in to the table at the time of insert. Later on all those programs adding duplicates will broadcast their protest, and when you fix them, this issue never comes up again.

Here is what I came up with. I was having major problems with this and believe I am in MVC 6 now but this may be helpful to someone even myself in the future..

//The issue was that Reqest.Form Request.Querystring and Request not working in MVC the solution is to use Context.Request.Form and also making sure the form has been submitted otherwise null reference or context issue bug will show up.

     if(Context.Request.ContentLength != null)
     {
         String StartDate = Context.Request.Form["StartMonth"].ToString();
         String EndMonth = Context.Request.Form["EndMonth"].ToString();
        // Vendor

     }

I had this same problem using DOM data in a Rails view created via the scaffold generator. By default the view omits <th> elements for the last three columns (which contain links to show, hide, and destroy records). I found that if I added in titles for those columns in a <th> element within the <thead> that it fixed the problem.

I can't say if this is the same problem you're having since I can't see your html. If it is not the same problem, you can use the chrome debugger to figure out which column it is erroring out on by clicking on the error in the console (which will take you to the code it is failing on), then adding a conditional breakpoint (at col==undefined). When it stops you can check the variable i to see which column it is currently on which can help you figure out what is different about that column from the others. Hope that helps!

flat list can be made through reduce easily.

All you need to use initializer - third argument in the reduce function.

reduce(
   lambda result, _list: result.append(
       list(set(_list)&set(c1)) 
     ) or result, 
   c2, 
   [])

Above code works for both python2 and python3, but you need to import reduce module as from functools import reduce. Refer below link for details.

• for python2

• for python3

For Swift 3.0:

button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 16)

where "boldSystemFont" and "16" can be replaced with your custom font and size.

If d is a dictionary, then d.get(k, v) means, give me the value of k in d, unless k isn't there, in which case give me v. It's being used here to get the current count of the character, which should start at 0 if the character hasn't been encountered before.

We can use TextViewCompact.setTextAppearance(textView, R.style.xyz).

You can install tomcat7 in ~/tomcat7 instead of /usr/share/tomcat7.

1. Close Eclipse.
2. Delete org.eclipse.wst.server.core.prefs and org.eclipse.jst.server.tomcat.core.prefs in {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings.
3. Launch Eclipse.
4. Go to Window->Show View->Other... and choose the Servers.
5. Select Tomcat v7.0 Server from the server type and press Next.
6. Enter /home/user/tomcat7 (not /usr/share/tomcat7) into the "Tomcat installation directory" and press Download.
7. Wait a few minutes and press Finish.

tomcat7 worked correctly with Eclipse 4.4 on my Ubuntu 15.04 in this way.

Another variation:

UPDATE test
SET field = IF ( {condition}, {new value}, field )
WHERE id = 123

This will update the field with {new value} only if {condition} is met

If you're using Bootstrap 3, you can use the Glyphicons.

.slick-prev:before, .slick-next:before {
    font-family: "Glyphicons Halflings", "slick", sans-serif;
    font-size: 40px;
}

.slick-prev:before { content: "\e257"; }
.slick-next:before { content: "\e258"; }

Please use these two methods for store data in ArrayList in kotlin

fun setDataInArrayList(list: ArrayList<ShopReisterRequest>, key: String, context: Context) {
    val prefs = PreferenceManager.getDefaultSharedPreferences(context)
    val editor = prefs.edit()
    val gson = Gson()
    val json = gson.toJson(list)
    editor.putString(key, json)
    editor.apply()   
}

fun getDataInArrayList(key: String, context: Context): ArrayList<ShopReisterRequest> {
    val prefs = PreferenceManager.getDefaultSharedPreferences(context)
    val gson = Gson()
    val json = prefs.getString(key, null)
    val type = object : TypeToken<ArrayList<ShopReisterRequest>>() {

    }.type
    return gson.fromJson<ArrayList<ShopReisterRequest>>(json, type)
}  

Usually, you would do something like this:

$post_data = json_encode(array('item' => $post_data));

But, as it seems you want the output to be with "{}", you better make sure to force json_encode() to encode as object, by passing the JSON_FORCE_OBJECT constant.

$post_data = json_encode(array('item' => $post_data), JSON_FORCE_OBJECT);

"{}" brackets specify an object and "[]" are used for arrays according to JSON specification.

After installation you need to connect to Server Name : localhost to start using the local instance of SQL Server.

Once you are connected to the local instance, right click on Databases and create a new database.

In general

There are two types of messages in FCM (Firebase Cloud Messaging):

• Display Messages: These messages trigger the onMessageReceived() callback only when your app is in foreground

• Data Messages: Theses messages trigger the onMessageReceived() callback even if your app is in foreground/background/killed

Data Messages example:

{ 
  "to": "/path", 
  "data": 
     { 
      "my_custom_key": "my_custom_value", 
      "my_custom_key2": true 
     } 
}

Display Messages example:

 {
     "notification": {
            "title" : "title",
            "body"  : "body text",
            "icon"  : "ic_notification",
            "click_action" : "OPEN_ACTIVITY_1"
        }
   }

Android side can handle notifications like:

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    …

      @Override public void onMessageReceived(RemoteMessage remoteMessage){
           Map<String, String> data = remoteMessage.getData();
           String myCustomKey = data.get("my_custom_key");
        
       } 

    …

}

They've changed it in JUnit 5 (expected: InvalidArgumentException, actual: invoked method) and code looks like this one:

@Test
public void wrongInput() {
    Throwable exception = assertThrows(InvalidArgumentException.class,
            ()->{objectName.yourMethod("WRONG");} );
}

After trying all the above and using the answer from @Aaron Hall, I was getting memory errors for a ~90 Mb file on a computer running Window 10, 8 Gb RAM and Python 3.5 32-bit. I was recommended by a colleague to use numpy instead and it works wonders.

By far, the fastest to read an entire binary file (that I have tested) is:

import numpy as np

file = "binary_file.bin"
data = np.fromfile(file, 'u1')

Reference

Multitudes faster than any other methods so far. Hope it helps someone!

If using Python 2.5, you may need to import simplejson:

Here is the official FAQ on installing Python Modules: http://docs.python.org/install/index.html

There are some tips which might help you.

When you reference Range like that it's called an unqualified reference because you don't specifically say which sheet the range is on. Unqualified references are handled by the "_Global" object that determines which object you're referring to and that depends on where your code is.

If you're in a standard module, unqualified Range will refer to Activesheet. If you're in a sheet's class module, unqualified Range will refer to that sheet.

inputTemplateContent is a variable that contains a reference to a range, probably a named range. If you look at the RefersTo property of that named range, it likely points to a sheet other than the Activesheet at the time the code executes.

The best way to fix this is to avoid unqualified Range references by specifying the sheet. Like

With ThisWorkbook.Worksheets("Template")
    .Range(inputTemplateHeader).Value = NO_ENTRY
    .Range(inputTemplateContent).Value = NO_ENTRY
End With

Adjust the workbook and worksheet references to fit your particular situation.

For Apache 2.4.9

in addition, look at the httpd-vhosts.conf file in C:\wamp\bin\apache\apache2.4.9\conf\extra

<VirtualHost *:80>
ServerName localhost
ServerAlias localhost
DocumentRoot C:/wamp/www
<Directory "C:/wamp/www/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Require local
</Directory>
</VirtualHost>

Change to:

<VirtualHost *:80>
ServerName localhost
ServerAlias localhost
DocumentRoot C:/wamp/www
<Directory "C:/wamp/www/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Require all granted
</Directory>
</VirtualHost>

changing from "Require local" to "Require all granted" solved the error 403 in my local network

Don't worry...! Follow these below steps and you will get your signed .apk file. I was also worry about that, but these step get ride me off from the frustration. Steps to sign your application:

1. Export the unsigned package:

Right click on the project in Eclipse -> Android Tools -> Export Unsigned Application Package (like here we export our GoogleDriveApp.apk to Desktop)

Sign the application using your keystore and the jarsigner tool (follow below steps):

Open cmd-->change directory where your "jarsigner.exe" exist (like here in my system it exist at "C:\Program Files\Java\jdk1.6.0_17\bin"

Now enter belwo command in cmd:

jarsigner -verbose -keystore c:\users\android\debug.keystore c:\users\pir fahim\Desktops\GoogleDriveApp.apk my_keystore_alias

It will ask you to provide your password: Enter Passphrase for keystore: It will sign your apk.To verify that the signing is successful you can run:

jarsigner -verify c:\users\pir fahim\Desktops\GoogleDriveApp.apk

It should come back with: jar verified.

Method 2

If you are using eclipse with ADT, then it is simple to compiled, signed, aligned, and ready the file for distribution.what you have to do just follow this steps.

• File > Export.
• Export android application
• Browse-->select your project
• Next-->Next

These steps will compiled, signed and zip aligned your project and now you are ready to distribute your project or upload at Google Play store.

The answer is to not use a regular expression. This is sets and counting.

Regular expressions are about order.

In your life as a programmer you will asked to do many things that do not make sense. Learn to dig a level deeper. Learn when the question is wrong.

The question (if it mentioned regular expressions) is wrong.

Pseudocode (been switching between too many languages, of late):

if s.length < 8:
    return False
nUpper = nLower = nAlphanum = nSpecial = 0
for c in s:
    if isUpper(c):
        nUpper++
    if isLower(c):
        nLower++
    if isAlphanumeric(c):
        nAlphanum++
    if isSpecial(c):
        nSpecial++
return (0 < nUpper) and (0 < nAlphanum) and (0 < nSpecial)

Bet you read and understood the above code almost instantly. Bet you took much longer with the regex, and are less certain it is correct. Extending the regex is risky. Extended the immediate above, much less so.

Note also the question is imprecisely phrased. Is the character set ASCII or Unicode, or ?? My guess from reading the question is that at least one lowercase character is assumed. So I think the assumed last rule should be:

return (0 < nUpper) and (0 < nLower) and (0 < nAlphanum) and (0 < nSpecial)

(Changing hats to security-focused, this is a really annoying/not useful rule.)

Learning to know when the question is wrong is massively more important than clever answers. A clever answer to the wrong question is almost always wrong.

I tried this in one of my databases.

To get it to work, the user had to be added to the database housing the actual data. No rights were needed, just access.

The common wisdom that floating-point numbers cannot be compared for equality is inaccurate. Floating-point numbers are no different from integers: If you evaluate "a == b", you will get true if they are identical numbers and false otherwise (with the understanding that two NaNs are of course not identical numbers).

The actual problem is this: If I have done some calculations and am not sure the two numbers I have to compare are exactly correct, then what? This problem is the same for floating-point as it is for integers. If you evaluate the integer expression "7/3*3", it will not compare equal to "7*3/3".

So suppose we asked "How do I compare integers for equality?" in such a situation. There is no single answer; what you should do depends on the specific situation, notably what sort of errors you have and what you want to achieve.

Here are some possible choices.

If you want to get a "true" result if the mathematically exact numbers would be equal, then you might try to use the properties of the calculations you perform to prove that you get the same errors in the two numbers. If that is feasible, and you compare two numbers that result from expressions that would give equal numbers if computed exactly, then you will get "true" from the comparison. Another approach is that you might analyze the properties of the calculations and prove that the error never exceeds a certain amount, perhaps an absolute amount or an amount relative to one of the inputs or one of the outputs. In that case, you can ask whether the two calculated numbers differ by at most that amount, and return "true" if they are within the interval. If you cannot prove an error bound, you might guess and hope for the best. One way of guessing is to evaluate many random samples and see what sort of distribution you get in the results.

Of course, since we only set the requirement that you get "true" if the mathematically exact results are equal, we left open the possibility that you get "true" even if they are unequal. (In fact, we can satisfy the requirement by always returning "true". This makes the calculation simple but is generally undesirable, so I will discuss improving the situation below.)

If you want to get a "false" result if the mathematically exact numbers would be unequal, you need to prove that your evaluation of the numbers yields different numbers if the mathematically exact numbers would be unequal. This may be impossible for practical purposes in many common situations. So let us consider an alternative.

A useful requirement might be that we get a "false" result if the mathematically exact numbers differ by more than a certain amount. For example, perhaps we are going to calculate where a ball thrown in a computer game traveled, and we want to know whether it struck a bat. In this case, we certainly want to get "true" if the ball strikes the bat, and we want to get "false" if the ball is far from the bat, and we can accept an incorrect "true" answer if the ball in a mathematically exact simulation missed the bat but is within a millimeter of hitting the bat. In that case, we need to prove (or guess/estimate) that our calculation of the ball's position and the bat's position have a combined error of at most one millimeter (for all positions of interest). This would allow us to always return "false" if the ball and bat are more than a millimeter apart, to return "true" if they touch, and to return "true" if they are close enough to be acceptable.

So, how you decide what to return when comparing floating-point numbers depends very much on your specific situation.

As to how you go about proving error bounds for calculations, that can be a complicated subject. Any floating-point implementation using the IEEE 754 standard in round-to-nearest mode returns the floating-point number nearest to the exact result for any basic operation (notably multiplication, division, addition, subtraction, square root). (In case of tie, round so the low bit is even.) (Be particularly careful about square root and division; your language implementation might use methods that do not conform to IEEE 754 for those.) Because of this requirement, we know the error in a single result is at most 1/2 of the value of the least significant bit. (If it were more, the rounding would have gone to a different number that is within 1/2 the value.)

Going on from there gets substantially more complicated; the next step is performing an operation where one of the inputs already has some error. For simple expressions, these errors can be followed through the calculations to reach a bound on the final error. In practice, this is only done in a few situations, such as working on a high-quality mathematics library. And, of course, you need precise control over exactly which operations are performed. High-level languages often give the compiler a lot of slack, so you might not know in which order operations are performed.

There is much more that could be (and is) written about this topic, but I have to stop there. In summary, the answer is: There is no library routine for this comparison because there is no single solution that fits most needs that is worth putting into a library routine. (If comparing with a relative or absolute error interval suffices for you, you can do it simply without a library routine.)

my friend by this u are not getting height of image stored in db.but you are getting view height.for getting height of image u have to create bitmap from db,s image.and than u can fetch height and width of imageview

You can use gcd to do this without having to create another method

double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
  NSLog(@"Do some work");
});

You should still ask yourself "do I really need to add a delay" as it can often complicate code and cause race conditions

While this is an old question, it's worth updating the answer to C++17. In the standard library there is now the templated function std::size(), which returns the number of elements in both a std container or a C-style array. For example:

#include <iterator>

uint32_t data[] = {10, 20, 30, 40};
auto dataSize = std::size(data);
// dataSize == 4

There's a new @config tag for these cases. They link to the preceding @param.

/** My function does X and Y.
    @params {object} parameters An object containing the parameters
    @config {integer} setting1 A required setting.
    @config {string} [setting2] An optional setting.
    @params {MyClass~FuncCallback} callback The callback function
*/
function(parameters, callback) {
    // ...
};

/**
 * This callback is displayed as part of the MyClass class.
 * @callback MyClass~FuncCallback
 * @param {number} responseCode
 * @param {string} responseMessage
 */

I create a student table with three column id, student,age. show you this example

declare @id int 
select @id = 1
while @id >=1 and @id <= 1000
begin
    insert into student values(@id, 'jack' + convert(varchar(5), @id), 12)
    select @id = @id + 1
end

this is the result about the example

In TensorFlow 2.0, you can use tf.config.experimental.list_physical_devices('GPU'):

import tensorflow as tf
gpus = tf.config.experimental.list_physical_devices('GPU')
for gpu in gpus:
    print("Name:", gpu.name, "  Type:", gpu.device_type)

If you have two GPUs installed, it outputs this:

Name: /physical_device:GPU:0   Type: GPU
Name: /physical_device:GPU:1   Type: GPU

From 2.1, you can drop experimental:

gpus = tf.config.list_physical_devices('GPU')

• Current API

You can use like this...

<div id="rot">hello</div>

#rot
{
   -webkit-transform: rotate(-90deg); 
   -moz-transform: rotate(-90deg);    
    width:100px;
}

Go to simplelogger.properties in ${MAVEN_HOME}/conf/logging/ and set the following properties:

org.slf4j.simpleLogger.defaultLogLevel=warn
org.slf4j.simpleLogger.log.Sisu=warn
org.slf4j.simpleLogger.warnLevelString=warn

And beware: warn, not warning

You're allowed to have more than one return statement, so it's legal to write

if (some_condition) {
  return true;
}
return false;

It's also unnecessary to compare boolean values to true or false, so you can write

if (verifyPwd())  {
  // do_task
}

Edit: Sometimes you can't return early because there's more work to be done. In that case you can declare a boolean variable and set it appropriately inside the conditional blocks.

boolean success = true;

if (some_condition) {
  // Handle the condition.
  success = false;
} else if (some_other_condition) {
  // Handle the other condition.
  success = false;
}
if (another_condition) {
  // Handle the third condition.
}

// Do some more critical things.

return success;

You would use the Console class

char[] password = console.readPassword("Enter password");  
Arrays.fill(password, ' ');

By executing readPassword echoing is disabled. Also after the password is validated it is best to overwrite any values in the array.

If you run this from an ide it will fail, please see this explanation for a thorough answer: Explained

Just to be sure that this is really the "conversion" you need, please note that jks files are keystores, a file format used to store more than one certificate and allows you to retrieve them programmatically using the Java security API, it's not a one-to-one conversion between equivalent formats.

So, if you just want to import that certificate in a new ad-hoc keystore you can do it with Keystore Explorer, a graphical tool. You'll be able to modify the keystore and the certificates contained therein like you would have done with the java terminal utilities like keytool (but in a more accessible way).

What it correct way of installing SmartGit on Ubuntu? Thus I can have normal icon

In smartgit/bin folder, there's a shell script waiting for you: add-menuitem.sh. It does just that.

Use this class (https://github.com/BlakeGardner/php-mac-address)

This is a PHP class for MAC address manipulation on top of Unix, Linux and Mac OS X operating systems. it was primarily written to help with spoofing for wireless security audits.

I had the same problem in writing the Kafka producer program using java. This error is coming due to the wrong slf4j library. use below slf4j-simple maven dependency that will fix your problem.

I believe the original post was about removing the space between the buttons in a row, not adding space.

The trick is that the minimum space between the buttons was due to padding built into the buttons as part of the material design specification.

So, don't use buttons! But a GestureDetector instead. This widget type give the onClick / onTap functionality but without the styling.

See this post for an example.

I believe that Mayras XML-approach can come in neat. However it is possible to make it more accurate, with one view only by setting the weightSum. I would not call this a hack anymore but in my opinion the most straightforward approach:

<LinearLayout android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:weightSum="1">
    <ImageView android:layout_height="fill_parent"
               android:layout_width="0dp"
               android:layout_weight="0.5"/>
</LinearLayout>

Like this you can use any weight, 0.6 for instance (and centering) is the weight I like to use for buttons.

Try this:

ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) + 
     geom_bar(position = 'dodge', stat='identity') +
     geom_text(aes(label=Number), position=position_dodge(width=0.9), vjust=-0.25)

Add a label= to each of your plot() calls, and then call legend(loc='upper left').

Consider this sample (tested with Python 3.8.0):

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 20, 1000)
y1 = np.sin(x)
y2 = np.cos(x)

plt.plot(x, y1, "-b", label="sine")
plt.plot(x, y2, "-r", label="cosine")
plt.legend(loc="upper left")
plt.ylim(-1.5, 2.0)
plt.show()

Slightly modified from this tutorial: http://jakevdp.github.io/mpl_tutorial/tutorial_pages/tut1.html

In addition to the Python 2 approach here are the equivalents for Python 3:

# Create a range that does not contain 50
for i in [x for x in range(100) if x != 50]:
    print(i)

# Create 2 ranges [0,49] and [51, 100]
from itertools import chain
concatenated = chain(range(50), range(51, 100))
for i in concatenated:
    print(i)

# Create a iterator and skip 50
xr = iter(range(100))
for i in xr:
    print(i)
    if i == 49:
        next(xr)

# Simply continue in the loop if the number is 50
for i in range(100):
    if i == 50:
        continue
    print(i)

Ranges are lists in Python 2 and iterators in Python 3.
