It is possible to use only one variable:

var timer = -performance.now();

// Do something

timer += performance.now();
console.log("Time: " + (timer/1000).toFixed(5) + " sec.")

timer/1000 - to convert milliseconds to seconds

.toFixed(5) - to trim extra digits

To add to existing answer - related name is a must in case there 2 FKs in the model that point to the same table. For example in case of Bill of material

@with_author 
class BOM(models.Model): 
    name = models.CharField(max_length=200,null=True, blank=True)
    description = models.TextField(null=True, blank=True)
    tomaterial =  models.ForeignKey(Material, related_name = 'tomaterial')
    frommaterial =  models.ForeignKey(Material, related_name = 'frommaterial')
    creation_time = models.DateTimeField(auto_now_add=True, blank=True)
    quantity = models.DecimalField(max_digits=19, decimal_places=10)

So when you will have to access this data you only can use related name

 bom = material.tomaterial.all().order_by('-creation_time')

It is not working otherwise (at least I was not able to skip the usage of related name in case of 2 FK's to the same table.)

Unfortunately using a list won't work in all situations. A list and an array are actually different and are not 100% interchangeable. It would depend on the circumstances if this would be an acceptable work around.

You can create table variables:

DECLARE @result1 TABLE (a INT, b INT, c INT)

INSERT INTO @result1
SELECT a, b, c
FROM table1

SELECT a AS val FROM @result1
UNION
SELECT b AS val FROM @result1
UNION
SELECT c AS val FROM @result1

This should be fine for what you need.

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

Without the requirement about the lowest index, you can use collections.Counter for this:

from collections import Counter

a = [1936, 2401, 2916, 4761, 9216, 9216, 9604, 9801] 

c = Counter(a)

print(c.most_common(1)) # the one most common element... 2 would mean the 2 most common
[(9216, 2)] # a set containing the element, and it's count in 'a'

You're putting Integers in so Python is giving you an integer back:

>>> 10 / 90
0

If if you cast this to a float afterwards the rounding will have already been done, in other words, 0 integer will always become 0 float.

If you use floats on either side of the division then Python will give you the answer you expect.

>>> 10 / 90.0
0.1111111111111111

So in your case:

>>> float(20-10) / (100-10)
0.1111111111111111
>>> (20-10) / float(100-10)
0.1111111111111111

I'm LATE to the party, but I had to solve this recently, figured I'd share the wealth.

const url = window.location.origin + window.location.pathname
//http://example.com/somedir/somefile/

window.location.origin will give you the base url, in our test case: http://example.com

window.location.pathname will give you the route path (after the base url), in our test case /somedir/somefile

SOLUTION 2

You can simply do the following to get rid of the query parameters.

const url = window.location.href.split('?')[0]

import sys
sys.version

will be getting answer like this

'2.7.6 (default, Oct 26 2016, 20:30:19) \n[GCC 4.8.4]'

here 2.7.6 is version

int *pointer[280]; //Creates 280 pointers of type int.

In 32 bit os, 4 bytes for each pointer. so 4 * 280 = 1120 bytes.

int (*pointer)[100][280]; // Creates only one pointer which is used to point an array of [100][280] ints.

Here only 4 bytes.

Coming to your question, int (*pointer)[280]; and int (*pointer)[100][280]; are different though it points to same 2D array of [100][280].

Because if int (*pointer)[280]; is incremented, then it will points to next 1D array, but where as int (*pointer)[100][280]; crosses the whole 2D array and points to next byte. Accessing that byte may cause problem if that memory doen't belongs to your process.

You can check whether the target is not your div-element and then issue another click event on the parent after which you will "return" from the handle.

$('clickable').click(function (event) {
    let div = $(event.target);
    if (! div.is('div')) {
       div.parent().click();
       return;
    }
    // Then Implement your logic here
}

Elegant way to fill combo box with an array list :

List<String> ls = new ArrayList<String>(); 
jComboBox.setModel(new DefaultComboBoxModel<String>(ls.toArray(new String[0])));

you can use the collector like this

  Stream<String> io = Stream.of("foo" , "lan" , "mql");
  io.collect(Collectors.toCollection(ArrayList<String>::new));

if you are already using jQuery in your build just do this:

$(yourObject).length

It works nicely for me on objects, and I already had jQuery as a dependancy.

As drewm himself said this is due to the subsequent redirect after the POST to the script has in fact succeeded. (I might have added this as a comment to his answer but you need 50 reputation to comment and I'm new round here - daft rule IMHO)

BUT it also applies if you're trying to redirect to a page, not just a directory - at least it did for me. I was trying to redirect to /thankyou.html. What fixes this is using an absolute URL, i.e. http://example.com/thankyou.html

Also remember, the same idea applies to variables. You will come across terms like static, member, instance, class and so on when talking about variables the same as you would for methods/functions.

It seems the common term in the Obj-C community is ivar for instance variable, but I am not an Obj-C guy, yet.

The first is a list, the second is a tuple. Lists are mutable, tuples are not.

Take a look at the Data Structures section of the tutorial, and the Sequence Types section of the documentation.

I want to slightly change the answer given by Wes, because version 0.16.2 requires as_index=False. If you don't set it, you get an empty dataframe.

Source:

Aggregation functions will not return the groups that you are aggregating over if they are named columns, when as_index=True, the default. The grouped columns will be the indices of the returned object.

Passing as_index=False will return the groups that you are aggregating over, if they are named columns.

Aggregating functions are ones that reduce the dimension of the returned objects, for example: mean, sum, size, count, std, var, sem, describe, first, last, nth, min, max. This is what happens when you do for example DataFrame.sum() and get back a Series.

nth can act as a reducer or a filter, see here.

import pandas as pd

df1 = pd.DataFrame({"Name":["Alice", "Bob", "Mallory", "Mallory", "Bob" , "Mallory"],
                    "City":["Seattle","Seattle","Portland","Seattle","Seattle","Portland"]})
print df1
#
#       City     Name
#0   Seattle    Alice
#1   Seattle      Bob
#2  Portland  Mallory
#3   Seattle  Mallory
#4   Seattle      Bob
#5  Portland  Mallory
#
g1 = df1.groupby(["Name", "City"], as_index=False).count()
print g1
#
#                  City  Name
#Name    City
#Alice   Seattle      1     1
#Bob     Seattle      2     2
#Mallory Portland     2     2
#        Seattle      1     1
#

EDIT:

In version 0.17.1 and later you can use subset in count and reset_index with parameter name in size:

print df1.groupby(["Name", "City"], as_index=False ).count()
#IndexError: list index out of range

print df1.groupby(["Name", "City"]).count()
#Empty DataFrame
#Columns: []
#Index: [(Alice, Seattle), (Bob, Seattle), (Mallory, Portland), (Mallory, Seattle)]

print df1.groupby(["Name", "City"])[['Name','City']].count()
#                  Name  City
#Name    City                
#Alice   Seattle      1     1
#Bob     Seattle      2     2
#Mallory Portland     2     2
#        Seattle      1     1

print df1.groupby(["Name", "City"]).size().reset_index(name='count')
#      Name      City  count
#0    Alice   Seattle      1
#1      Bob   Seattle      2
#2  Mallory  Portland      2
#3  Mallory   Seattle      1

The difference between count and size is that size counts NaN values while count does not.

What about something like this?

>>> bin(int('ff', base=16))
'0b11111111'

This will convert the hexadecimal string you have to an integer and that integer to a string in which each byte is set to 0/1 depending on the bit-value of the integer.

As pointed out by a comment, if you need to get rid of the 0b prefix, you can do it this way:

>>> bin(int('ff', base=16)).lstrip('0b')
'11111111'

or this way:

>>> bin(int('ff', base=16))[2:]
'11111111'

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

This is a block of Ruby code that takes advantage of a Rails helper method. If you aren't familiar with blocks yet, you will see them a lot in Ruby.

respond_to is a Rails helper method that is attached to the Controller class (or rather, its super class). It is referencing the response that will be sent to the View (which is going to the browser).

The block in your example is formatting data - by passing in a 'format' paramater in the block - to be sent from the controller to the view whenever a browser makes a request for html or json data.

If you are on your local machine and you have your Post scaffold set up, you can go to http://localhost:3000/posts and you will see all of your posts in html format. But, if you type in this: http://localhost:3000/posts.json, then you will see all of your posts in a json object sent from the server.

This is very handy for making javascript heavy applications that need to pass json back and forth from the server. If you wanted, you could easily create a json api on your rails back-end, and only pass one view - like the index view of your Post controller. Then you could use a javascript library like Jquery or Backbone (or both) to manipulate data and create your own interface. These are called asynchronous UIs and they are becomming really popular (Gmail is one). They are very fast and give the end-user a more desktop-like experience on the web. Of course, this is just one advantage of formatting your data.

The Rails 3 way of writing this would be this:

    class PostsController < ApplicationController
      # GET /posts
      # GET /posts.xml


      respond_to :html, :xml, :json

      def index
        @posts = Post.all

        respond_with(@posts)
      end

#
# All your other REST methods
#

end

By putting respond_to :html, :xml, :json at the top of the class, you can declare all the formats that you want your controller to send to your views.

Then, in the controller method, all you have to do is respond_with(@whatever_object_you_have)

It just simplifies your code a little more than what Rails auto-generates.

If you want to know about the inner-workings of this...

From what I understand, Rails introspects the objects to determine what the actual format is going to be. The 'format' variables value is based on this introspection. Rails can do a whole lot with a little bit of info. You'd be surprised at how far a simple @post or :post will go.

For example, if I had a _user.html.erb partial file that looked like this:

_user.html.erb

<li>    
    <%= link_to user.name, user %>
</li>

Then, this alone in my index view would let Rails know that it needed to find the 'users' partial and iterate through all of the 'users' objects:

index.html.erb

 <ul class="users">
   <%= render @users %>     
 </ul>

would let Rails know that it needed to find the 'user' partial and iterate through all of the 'users' objects:

You can also peruse the source: https://github.com/rails/rails

<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

You can use finds null separated output option with read to iterate over directory structures safely.

#!/bin/bash
find . -type f -print0 | while IFS= read -r -d $'\0' file; 
  do echo "$file" ;
done

So for your case

#!/bin/bash
find . -maxdepth 1 -type f  -print0 | while IFS= read -r -d $'\0' file; do
  for ((i=0; i<=3; i++)); do
    ./MyProgram.exe "$file" 'Logs/'"`basename "$file"`""$i"'.txt'
  done
done

additionally

#!/bin/bash
while IFS= read -r -d $'\0' file; do
  for ((i=0; i<=3; i++)); do
    ./MyProgram.exe "$file" 'Logs/'"`basename "$file"`""$i"'.txt'
  done
done < <(find . -maxdepth 1 -type f  -print0)

will run the while loop in the current scope of the script ( process ) and allow the output of find to be used in setting variables if needed

$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
$mail->Host = "smtp.gmail.com";
$mail->Port = 465; // or 587
$mail->IsHTML(true);
$mail->Username = "[email protected]";
$mail->Password = "password";
$mail->SetFrom("[email protected]");
$mail->Subject = "Test";
$mail->Body = "hello";
$mail->AddAddress("[email protected]");

 if(!$mail->Send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
 } else {
    echo "Message has been sent";
 }

This code above has been tested and worked for me.

It could be that you needed $mail->SMTPSecure = 'ssl';

Also make sure you don't have two step verification switched on for that account as that can cause problems also.

UPDATED

You could try changing $mail->SMTP to:

$mail->SMTPSecure = 'tls';

It's worth noting that some SMTP servers block connections. Some SMTP servers don't support SSL (or TLS) connections.

Step one: enable 2FA

• https://myaccount.google.com/signinoptions/two-step-verification/enroll-welcome

Step two: create an app-specific password

• https://myaccount.google.com/apppasswords

After this, put the sixteen digits password to the settings and reload the app, enjoy!

Your example is perfect: the field is private and it has a getter. This is the normal way to access a field. If you need a direct access to an object field, use reflection. Using reflection to get a field's value is a hack and should be used in extreme cases such as using a library whose code you cannot change.

In your generic method, T is just a placeholder for a type. However, the compiler doesn't per se know anything about the concrete type(s) being used runtime, so it can't assume that they will have a var member.

The usual way to circumvent this is to add a generic type constraint to your method declaration to ensure that the types used implement a specific interface (in your case, it could be ITest):

public void PrintGeneric<T>(T test) where T : ITest

Then, the members of that interface would be directly available inside the method. However, your ITest is currently empty, you need to declare common stuff there in order to enable its usage within the method.

If you already have the Groovy (Postbuild) plugin installed, I think it's a valid desire to get this done with (generic) Groovy instead of installing a (specialized) plugin.

That said, you can get the workspace using manager.build.workspace.getRemote(). Don't forget to add File.separator between path and file name.

one things to remember push work only with array[] not object{}.

if you want to add Like object o inside inside n

_x000D_
_x000D_
a={ b:"c",
D:"e",
F: {g:"h",
I:"j",
k:{ l:"m"
}}
}

a.F.k.n = { o: "p" };
a.F.k.n = { o: "p" };
console.log(a);

import datetime
def today_date():
    '''
    utils:
    get the datetime of today
    '''
    date=datetime.datetime.now().date()
    date=pd.to_datetime(date)
    return date
Df['Date'] = today_date()

this could be safely used in pandas dataframes.

I had a simular issue and resolved it using android:adjustViewBounds="true" on the ImageView.

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:contentDescription="@string/banner_alt"
    android:src="@drawable/banner_portrait" />

Use the MemoryStream class, calling Encoding.GetBytes to turn your string into an array of bytes first.

Do you subsequently need a TextReader on the stream? If so, you could supply a StringReader directly, and bypass the MemoryStream and Encoding steps.

To make it with jquery, make this way:

var test = $("input[name=testing]:hidden");
test.val('work!');

Or

var test = $("input[name=testing]:hidden").val('work!');

See working in this fiddle.

You can use the following code to check if a textbox object is null/empty

'Checks if the box is null

If Me.TextBox & "" <> "" Then

        'Enter Code here...

End if

For people developing with Android studio:

if you install adb with the command line it will probably conflict with the adb version installed by Flutter.

Analysis of issue's origin

You can check that you have this problem with 2 different versions easily:

find /home -iname "*adb"|grep -i android

And then compare the return value between adb version (located at usr/bin/adb and most likely a symbolic link for /usr/lib/android-sdk/platform-tools/adb ) with ~/Android/Sdk/platform-tools/adb version

You will get this kind of output:

$ ~/Android/Sdk/platform-tools/adb version
Android Debug Bridge version 1.0.41
Version 30.0.5-6877874
Installed as /home/{{{user}}/Android/Sdk/platform-tools/adb

$ adb version
Android Debug Bridge version 1.0.39
Version 1:8.1.0+r23-5~18.04
Installed as /usr/lib/android-sdk/platform-tools/adb

My advice is hence the following: DO NOT RELY ON sudo apt-get install adb

Solution

1/ You first want to remove adb installed through the command line: (this is way cleaner than sudo rm usr/bin/adb

sudo apt-get remove adb

2/ Then create symbolic link from the sdk to usr/bin (top answer already provided):

sudo ln -s ~/Android/Sdk/platform-tools/adb  /usr/bin/adb

Now you can use the different command lines adb devices, adb start-server, adb kill-server

I changed the memory limit from .htaccess and this problem got resolved.

I was trying to scan my website from one of the antivirus plugin and there I was getting this problem. I increased memory by pasting this in my .htaccess file in Wordpress folder:

php_value memory_limit 512M

After scan was over, I removed this line to make the size as it was before.

Let’s say you are making an executable that uses some functions found in a library.

If the library you are using is static, the linker will copy the object code for these functions directly from the library and insert them into the executable.

Now if this executable is run it has every thing it needs, so the executable loader just loads it into memory and runs it.

If the library is dynamic the linker will not insert object code but rather it will insert a stub which basically says this function is located in this DLL at this location.

Now if this executable is run, bits of the executable are missing (i.e the stubs) so the loader goes through the executable fixing up the missing stubs. Only after all the stubs have been resolved will the executable be allowed to run.

To see this in action delete or rename the DLL and watch how the loader will report a missing DLL error when you try to run the executable.

Hence the name Dynamic Link Library, parts of the linking process is being done dynamically at run time by the executable loader.

One a final note, if you don't link to the DLL then no stubs will be inserted by the linker, but Windows still provides the GetProcAddress API that allows you to load an execute the DLL function entry point long after the executable has started.

Have you tried height: auto; on your .container div?

Here is a fiddle, if you change img height, container height will adjust to it.

EDIT

So if you "can't" change the inline min-height, you can overwrite the inline style with an !important parameter. It's not the cleanest way, but it solves your problem.

add to your .containerclass this line

min-height:0px !important;

I've updated my fiddle to give you an example.

Starting from Bootstrap v4 you can simply add the following to your div class attribute: mt-2 (margin top 2)

<div class="mt-2 col-md-12">
        This will have a two-point top margin!
</div>

More examples are given in the docs: Bootstrap v4 docs

Check google-services.json file in app folder of your Android project. Generate a new one from Firebase console if you are unsure. I got this error in two cases.

1. I used a test Firebase project with test application (that contained right google-services.json file). Then I tried to send push notification to another application and got this error ('"error": "MismatchSenderId"'). I understood that the second application was bound to another Firebase project with different google-services.json. Because server keys are different, the request should be rewritten.

2. I changed google-services.json in the application, because I wanted to replace test Firebase project with an actual. I generated right google-services.json file, changed request, but kept receiving this error. On the next day it fixed itself. I suspect Firebase doesn't update synchronously.

To get a server key for the request, open https://console.firebase.google.com and select an appropriate project.

Then paste it in the request.

The code is very large, but easy to understand. I think it fits your situation.

alphabet = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz"
class CaesarCipher(object):    
    def __init__(self, shift):
        self.shift = shift
    def encode(self, str):
        encode = ''
        str = str.lower()
        for i in str:
            if i in alphabet:
                encode += alphabet[alphabet.index(i) + self.shift]
            else:
                encode += i
    
        return encode.upper()


    def decode(self, str):
        decode = ''
        str = str.lower()
        for i in str:
            if i in alphabet:
                decode += alphabet[alphabet.index(i) - self.shift]
            else:
                decode += i
        return decode.upper()
    

The problem is with implicit conversion.

If you have Unicode/nChar/nVarChar values you are concatenating, then SQL Server will implicitly convert your string to nVarChar(4000), and it is unfortunately too dumb to realize it will truncate your string or even give you a Warning that data has been truncated for that matter!

When concatenating long strings (or strings that you feel could be long) always pre-concatenate your string building with CAST('' as nVarChar(MAX)) like so:

SET @Query = CAST('' as nVarChar(MAX))--Force implicit conversion to nVarChar(MAX)
           + 'SELECT...'-- some of the query gets set here
           + '...'-- more query gets added on, etc.

What a pain and scary to think this is just how SQL Server works. :(

I know other workarounds on the web say to break up your code into multiple SET/SELECT assignments using multiple variables, but this is unnecessary given the solution above.

For those who hit an 8000 character max, it was probably because you had no Unicode so it was implicitly converted to VarChar(8000).

Explanation:
What's happening behind the scenes is that even though the variable you are assigning to uses (MAX), SQL Server will evaluate the right-hand side of the value you are assigning first and default to nVarChar(4000) or VarChar(8000) (depending on what you're concatenating). After it is done figuring out the value (and after truncating it for you) it then converts it to (MAX) when assigning it to your variable, but by then it is too late.

Your where clause should have worked. I am at a loss as to why it didn't. Let me show you how I would have figured out the problem with the where clause as it might help you for the future.

When I create triggers, I start at the query window by creating a temp table called #inserted (and or #deleted) with all the columns of the table. Then I popultae it with typical values (Always multiple records and I try to hit the test cases in the values)

Then I write my triggers logic and I can test without it actually being in a trigger. In a case like your where clause not doing what was expected, I could easily test by commenting out the insert to see what the select was returning. I would then probably be easily able to see what the problem was. I assure you that where clasues do work in triggers if they are written correctly.

Once I know that the code works properly for all the cases, I global replace #inserted with inserted and add the create trigger code around it and voila, a tested trigger.

AS I said in a comment, I have a concern that the solution you picked will not work properly in a multiple record insert or update. Triggers should always be written to account for that as you cannot predict if and when they will happen (and they do happen eventually to pretty much every table.)

If nothing is working you can remove the CSRF security check by going to App/Http/Middleware/VerifyCsrfToken.php file and adding your routes to protected $excpt.

e.g. if i want to remove CSRF protection from all routes.

protected $except = [
    '/*'
];

P.S although its a good practice to include CSRF protection.

getActionCommand()

Returns the command string associated with this action. This string allows a "modal" component to specify one of several commands, depending on its state. For example, a single button might toggle between "show details" and "hide details". The source object and the event would be the same in each case, but the command string would identify the intended action.

IMO, this is useful in case you a single command-component to fire different commands based on it's state, and using this method your handler can execute the right lines of code.

JTextField has JTextField#setActionCommand(java.lang.String) method that you can use to set the command string used for action events generated by it.

getSource()

Returns: The object on which the Event initially occurred.

We can use getSource() to identify the component and execute corresponding lines of code within an action-listener. So, we don't need to write a separate action-listener for each command-component. And since you have the reference to the component itself, you can if you need to make any changes to the component as a result of the event.

If the event was generated by the JTextField then the ActionEvent#getSource() will give you the reference to the JTextField instance itself.

char = split_string_to_char(text)(index)

------

Function split_string_to_char(text) As String()

   Dim chars() As String
   For char_count = 1 To Len(text)
      ReDim Preserve chars(char_count - 1)
      chars(char_count - 1) = Mid(text, char_count, 1)
   Next
   split_string_to_char = chars

Your FMAT.h requires a definition of std::string in order to complete the definition of class FMAT. In FMAT.cpp, you've done this by #include <string> before #include "FMAT.h". You haven't done that in your main file.

Your attempt to forward declare string was incorrect on two levels. First you need a fully qualified name, std::string. Second this works only for pointers and references, not for variables of the declared type; a forward declaration doesn't give the compiler enough information about what to embed in the class you're defining.

With the lib config option your are able to cherry pick Map into your project. Just add es2015.collection to your lib section. When you have no lib config add one with the defaults and add es2015.collection.

So when you have target: es5, change tsconfig.json to:

"target": "es5",
"lib": [ "dom", "es5", "scripthost", "es2015.collection" ],

Run the code either in onload event, either just before you close body tag. You try to find an element wich is not there at the moment you do it.

Not possible with vanilla CSS. However you can use something like:

• Sass

Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.

Or

• Less

Rather than constructing long selector names to specify inheritance, in Less you can simply nest selectors inside other selectors. This makes inheritance clear and style sheets shorter.

Example:

#header {
  color: red;
  a {
    font-weight: bold;
    text-decoration: none;
  }
}

Are you asking about absolute values?

Math.abs(...) is the function you probably want.

What saved me from this error was when I changed my Bundle Identifier.

Try and do that

If you import os you can use os.getcwd to get the current working directory, and you can use os.chdir to change your directory

I often just open the console and look for the solution in the objects methods. Quite often it's already there:

>>> a = "hello ' s"
>>> dir(a)
[ (....) 'partition', 'replace' (....)]
>>> a.replace("'", " ")
'hello   s'

Short answer: Use string.replace().

Use sdp library which is provided in Github

In Swift 4.2 I would do something like that:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if let yourVC = segue.destination as? YourViewController {
        yourVC.yourData = self.someData
    }
}

Default Bootstrap size classes

You can use btn-lg, btn-sm and btn-xs classes for manipulating with its size.

btn-block

Also, there is a class btn-block which will extend your button to the whole block. It is very convenient in combination with Bootstrap grid.
For example, this code will show a button with the width equal to half of screen for medium and large screens; and will show a full-width button for small screens:

<div class="container">
    <div class="col-xs-12 col-xs-offset-0 col-sm-offset-3 col-sm-6">
        <button class="btn btn-group">Click me!</button>
    </div>
</div>

Check this JSFiddle out. Try to resize frame.

If it is not enough, you can easily create your custom class.

You can convert a string to a date easily by:

CAST(YourDate AS DATE)

UPDATED#2

Explanation is in Blue Moons's answer.

Alternative solutions:

Eliminate echo

while read line; do
...
done <<EOT
first line
second line
third line
EOT

Add the echo inside the here-is-the-document

while read line; do
...
done <<EOT
$(echo -e $lines)
EOT

Run echo in background:

coproc echo -e $lines
while read -u ${COPROC[0]} line; do 
...
done

Redirect to a file handle explicitly (Mind the space in < <!):

exec 3< <(echo -e  $lines)
while read -u 3 line; do
...
done

Or just redirect to the stdin:

while read line; do
...
done < <(echo -e  $lines)

And one for chepner (eliminating echo):

arr=("first line" "second line" "third line");
for((i=0;i<${#arr[*]};++i)) { line=${arr[i]}; 
...
}

Variable $lines can be converted to an array without starting a new sub-shell. The characters \ and n has to be converted to some character (e.g. a real new line character) and use the IFS (Internal Field Separator) variable to split the string into array elements. This can be done like:

lines="first line\nsecond line\nthird line"
echo "$lines"
OIFS="$IFS"
IFS=$'\n' arr=(${lines//\\n/$'\n'}) # Conversion
IFS="$OIFS"
echo "${arr[@]}", Length: ${#arr[*]}
set|grep ^arr

Result is

first line\nsecond line\nthird line
first line second line third line, Length: 3
arr=([0]="first line" [1]="second line" [2]="third line")

Further to @pmg's answer, note that you can do both operations in one statement:

char mystr[] = "Nmy stringP";
char *p = mystr;
p++[strlen(p)-1] = 0;

This will likely work as expected but behavior is undefined in C standard.

Just wanted to update this thread for future developers.

JQuery >1.12 Now supports being able to change every little piece of the request through JQuery.post ($.post({...}). see second function signature in https://api.jquery.com/jquery.post/

Wanted to add my experience with converting. I had many text fields in ancient Linq2SQL code. This was to allow text columns present in indexes to be rebuilt ONLINE.

First I've known about the benefits for years, but always assumed that converting would mean some scary long queries where SQL Server would have to rebuild the table and copy everything over, bringing down my websites and raising my heartrate.

I was also concerned that the Linq2SQL could cause errors if it was doing some kind of verification of the column type.

Happy to report though, that the ALTER commands returned INSTANTLY - so they are definitely only changing table metadata. There may be some offline work happening to bring <8000 character data back to be in-table, but the ALTER command was instant.

I ran the following to find all columns needing conversion:

SELECT concat('ALTER TABLE dbo.[', table_name, '] ALTER COLUMN [', column_name, '] VARCHAR(MAX)'), table_name, column_name
FROM information_schema.columns where data_type = 'TEXT' order by table_name, column_name

SELECT concat('ALTER TABLE dbo.[', table_name, '] ALTER COLUMN [', column_name, '] NVARCHAR(MAX)'), table_name, column_name
FROM information_schema.columns where data_type = 'NTEXT' order by table_name, column_name

This gave me a nice list of queries, which I just selected and copied to a new window. Like I said - running this was instant.

Linq2SQL is pretty ancient - it uses a designer that you drag tables onto. The situation may be more complex for EF Code first but I haven't tackled that yet.

The basename command has two different invocations; in one, you specify just the path, in which case it gives you the last component, while in the other you also give a suffix that it will remove. So, you can simplify your example code by using the second invocation of basename. Also, be careful to correctly quote things:

fbname=$(basename "$1" .txt)
echo "$fbname"

Not necessarily true. It will be encrypted on the wire however it still lands in the logs plain text

we can call it after loaded

        $scope.message = "hi robi";
        $scope.updateMessage = function(_s){
            $scope.message = _s;    
        };
    }

function hi(){
    var scope = angular.element(document.getElementById("wrap")).scope();
        scope.$apply(function() {
        scope.info = "nami";
        scope.updateMessage("i am new fans like nami");
    });
}

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

Yes, Spring framework logging is very detailed, You did not mention in your post, if you are already using a logging framework or not. If you are using log4j then just add spring appenders to the log4j config (i.e to log4j.xml or log4j.properties), If you are using log4j xml config you can do some thing like this

<category name="org.springframework.beans">
    <priority value="debug" />
</category>

or

<category name="org.springframework">
    <priority value="debug" />
</category>

I would advise you to test this problem in isolation using JUnit test, You can do this by using spring testing module in conjunction with Junit. If you use spring test module it will do the bulk of the work for you it loads context file based on your context config and starts container so you can just focus on testing your business logic. I have a small example here

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:springContext.xml"})
@Transactional
public class SpringDAOTest 
{
    @Autowired
    private SpringDAO dao;

    @Autowired
    private ApplicationContext appContext;

    @Test
    public void checkConfig()
    {
        AnySpringBean bean =  appContext.getBean(AnySpringBean.class);
        Assert.assertNotNull(bean);
    }
}

UPDATE

I am not advising you to change the way you load logging but try this in your dev environment, Add this snippet to your web.xml file

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/log4j.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

UPDATE log4j config file

I tested this on my local tomcat and it generated a lot of logging on application start up. I also want to make a correction: use debug not info as @Rayan Stewart mentioned.

cursor.execute(sql,array)

Only takes two arguments.
It will iterate the "array"-object and match ? in the sql-string.
(with sanity checks to avoid sql-injection)

Instance variable is the variable declared inside a class, but outside a method: something like:

class IronMan {

    /** These are all instance variables **/
    public String realName;
    public String[] superPowers;
    public int age;

    /** Getters and setters here **/
}

Now this IronMan Class can be instantiated in another class to use these variables. Something like:

class Avengers {

    public static void main(String[] a) {
        IronMan ironman = new IronMan();
        ironman.realName = "Tony Stark";
        // or
        ironman.setAge(30);
    }

}

This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.

If you have the char array null terminated, you can assign the char array to the string:

char[] chArray = "some characters";
String String(chArray);

As for your loop code, it looks right, but I will try on my controller to see if I get the same problem.

Weak entity exists to solve the multi-valued attributes problem.

There are two types of multi-valued attributes. One is the simply many values for an objects such as a "hobby" as an attribute for a student. The student can have many different hobbies. If we leave the hobbies in the student entity set, "hobby" would not be unique any more. We create a separate entity set as hobby. Then we link the hobby and the student as we need. The hobby entity set is now an associative entity set. As to whether it is weak or not, we need to check whether each entity has enough unique identifiers to identify it. In many opinion, a hobby name can be enough to identify it.

The other type of multi-valued attribute problem does need a weak entity to fix it. Let's say an item entity set in a grocery inventory system. Is the item a category item or the actually item? It is an important question, because a customer can buy the same item at one time and at a certain amount, but he can also buy the same item at a different time with a different amount. Can you see it the same item but of different objects. The item now is a multi-valued attribute. We solve it by first separate the category item with the actual item. The two are now different entity sets. Category item has descriptive attributes of the item, just like the item you usually think of. Actual item can not have descriptive attributes any more because we can not have redundant problem. Actual item can only have date time and amount of the item. You can link them as you need. Now, let's talk about whether one is a weak entity of the other. The descriptive attributes are more than enough to identify each entity in the category item entity set. The actual item only has date time and amount. Even if we pull out all the attributes in a record, we still cannot identify the entity. Think about it is just time and amount. The actual item entity set is a weak entity set. We identify each entity in the set with the help of duplicate prime key from the category item entity set.

This simply removes everything before the last slash, including it.

This happens because of your application does not allow to append iframe from origin other than your application domain.

If your application have web.config then add the following tag in web.config

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <add name="X-Frame-Options" value="ALLOW" />
        </customHeaders>
    </httpProtocol>
</system.webServer>

This will allow application to append iframe from other origin also. You can also use the following value for X-Frame-Option

X-FRAME-OPTIONS: ALLOW-FROM https://example.com/ 

I'd stay with two different interfaces.

You said that 'I want to group my service executors under a common interface... It also seems overkill creating two separate interfaces for the two different service calls... A class will only implement one of these interfaces'

It's not clear what is the reason to have a single interface then. If you want to use it as a marker, you can just exploit annotations instead.

Another point is that there is a possible case that your requirements change and method(s) with another signature appears at the interface. Of course it's possible to use Adapter pattern then but it would be rather strange to see that particular class implements interface with, say, three methods where two of them trow UnsupportedOperationException. It's possible that the forth method appears etc.

The best way to deal with angle computation is to use atan2(y, x) that given a point x, y returns the angle from that point and the X+ axis in respect to the origin.

Given that the computation is

double result = atan2(P3.y - P1.y, P3.x - P1.x) -
                atan2(P2.y - P1.y, P2.x - P1.x);

i.e. you basically translate the two points by -P1 (in other words you translate everything so that P1 ends up in the origin) and then you consider the difference of the absolute angles of P3 and of P2.

The advantages of atan2 is that the full circle is represented (you can get any number between -p and p) where instead with acos you need to handle several cases depending on the signs to compute the correct result.

The only singular point for atan2 is (0, 0)... meaning that both P2 and P3 must be different from P1 as in that case doesn't make sense to talk about an angle.

This answer is obsolete. Technology has moved on. Unless you're working with legacy systems see Joel's answer.

There is no string concatenation operator in EL. If you don't need the concatenated string to pass into some other operation, just put these expressions next to each other:

${value}${(empty value)? 'none' : ' enabled'}

For attributes whose type is an immutable value class that conforms to the NSCopying protocol, you almost always should specify copy in your @property declaration. Specifying retain is something you almost never want in such a situation.

Here's why you want to do that:

NSMutableString *someName = [NSMutableString stringWithString:@"Chris"];

Person *p = [[[Person alloc] init] autorelease];
p.name = someName;

[someName setString:@"Debajit"];

The current value of the Person.name property will be different depending on whether the property is declared retain or copy — it will be @"Debajit" if the property is marked retain, but @"Chris" if the property is marked copy.

Since in almost all cases you want to prevent mutating an object's attributes behind its back, you should mark the properties representing them copy. (And if you write the setter yourself instead of using @synthesize you should remember to actually use copy instead of retain in it.)

This is quite likely the simplest way to achieve what you are looking for.

In order to use this map function in this instance, we will have to pass a currentValue (always-required) parameter, as well an index (optional) parameter. In the below example, station is our currentValue, and x is our index.

station represents the current value of the object within the array as it is iterated over. x automatically increments; increasing by one each time a new object is mapped.

render () {
    return (
        <div>
            {stations.map((station, x) => (
                <div key={x}> {station} </div>
            ))}
        </div>
    );
}

What Thomas Valadez had answered, while it had provided the best/simplest method to render a component from an array of objects, it had failed to properly address the way in which you would assign a key during this process.

We can write something like this. I have used with python-3.7.x

import sys

def print_fn():
    print("Hi")

def sum_fn(a, b):
    print(a + b)

if __name__ == "__main__":
    args = sys.argv
    # args[0] = current file
    # args[1] = function name
    # args[2:] = function args : (*unpacked)
    globals()[args[1]](*args[2:])

python demo.py print_fn
python demo.py sum_fn 5 8

String url = "https://www.murait.com/";
if (url.startsWith("https://") || url.startsWith("http://")) {
    Uri uri = Uri.parse(url);
    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
    startActivity(intent);
}else{
    Toast.makeText(mContext, "Invalid Url", Toast.LENGTH_SHORT).show();
}

You have to check that the URL is valid or not. If URL is invalid application may crash so that you have to check URL is valid or not by this method.

I use codeignator and I got the error:

Object of class stdClass could not be converted to string.

for this post I get my result

I use in my model section

$query = $this->db->get('user', 10);
        return $query->result();

and from this post I use

$query = $this->db->get('user', 10);
        return $query->row();

and I solved my problem

No, if a is true (in a or test), b will not be tested, as the result of the test will always be true, whatever is the value of the b expression.

Make a simple test:

if (true || ((String) null).equals("foobar")) {
    ...
}

will not throw a NullPointerException!

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?

here you can see NestedVM

NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.

Example: Cross compile Hello world C program and run it on android

I got same problem, but i was thinking we should not use the set datetime things on the same class. because it could lead to misuse one day. so i have used the provider like

public class DateTimeProvider
{
    protected static DateTime? DateTimeNow;
    protected static DateTime? DateTimeUtcNow;

    public DateTime Now
    {
        get
        {
            return DateTimeNow ?? System.DateTime.Now;
        }
    }

    public DateTime UtcNow
    {
        get
        {
            return DateTimeUtcNow ?? System.DateTime.UtcNow;
        }
    }

    public static DateTimeProvider DateTime
    {
        get
        {
            return new DateTimeProvider();
        }
    }

    protected DateTimeProvider()
    {       
    }
}

For tests, at test project made a helper which will deal with set things,

public class MockDateTimeProvider : DateTimeProvider
{
    public static void SetNow(DateTime now)
    {
        DateTimeNow = now;
    }

    public static void SetUtcNow(DateTime utc)
    {
        DateTimeUtcNow = utc;
    }

    public static void RestoreAsDefault()
    {
        DateTimeNow = null;
        DateTimeUtcNow = null;
    }
}

on code

var dateTimeNow = DateTimeProvider.DateTime.Now         //not DateTime.Now
var dateTimeUtcNow = DateTimeProvider.DateTime.UtcNow   //not DateTime.UtcNow

and on tests

[Test]
public void Mocked_Now()
{
    DateTime now = DateTime.Now;
    MockDateTimeProvider.SetNow(now);    //set to mock
    Assert.AreEqual(now, DateTimeProvider.DateTime.Now);
    Assert.AreNotEqual(now, DateTimeProvider.DateTime.UtcNow);
}

[Test]
public void Mocked_UtcNow()
{
    DateTime utcNow = DateTime.UtcNow;
    MockDateTimeProvider.SetUtcNow(utcNow);   //set to mock
    Assert.AreEqual(utcNow, DateTimeProvider.DateTime.UtcNow);
    Assert.AreNotEqual(utcNow, DateTimeProvider.DateTime.Now);
}

But need to remember one thing, sometime the real DateTime and provider's DateTime doesn't act same

[Test]
public void Now()
{
    Assert.AreEqual(DateTime.Now.Kind, DateTimeProvider.DateTime.Now.Kind);
    Assert.LessOrEqual(DateTime.Now, DateTimeProvider.DateTime.Now);
    Assert.LessOrEqual(DateTimeProvider.DateTime.Now - DateTime.Now, TimeSpan.FromMilliseconds(1));
}

I assumed the deference would be maximum TimeSpan.FromMilliseconds(0.00002). But most of the time it's even less

Find the sample at MockSamples

1. In your project folder, create a “.gdbinit” text file. It will contain your gdb debugger configuration
2. Edit “.gdbinit”, and add the line (without the quotes) : “set new-console on”

3. After building the project right click on the project Debug > “Debug Configurations”, as shown below

4. In the “debugger” tab, ensure the “GDB command file” now points to your “.gdbinit” file. Else, input the path to your “.gdbinit” configuration file :

5. Click “Apply” and “Debug”. A native DOS command line should be launched as shown below

My way of achieving this is by creating ZipInputStream wrapping class that would handle that would provide only the stream of current entry:

The wrapper class:

public class ZippedFileInputStream extends InputStream {

    private ZipInputStream is;

    public ZippedFileInputStream(ZipInputStream is){
        this.is = is;
    }

    @Override
    public int read() throws IOException {
        return is.read();
    }

    @Override
    public void close() throws IOException {
        is.closeEntry();
    }

}

The use of it:

    ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream("SomeFile.zip"));

    while((entry = zipInputStream.getNextEntry())!= null) {

     ZippedFileInputStream archivedFileInputStream = new ZippedFileInputStream(zipInputStream);

     //... perform whatever logic you want here with ZippedFileInputStream 

     // note that this will only close the current entry stream and not the ZipInputStream
     archivedFileInputStream.close();

    }
    zipInputStream.close();

One advantage of this approach: InputStreams are passed as an arguments to methods that process them and those methods have a tendency to immediately close the input stream after they are done with it.

Things that can cause a delete to be slow:

• deleting a lot of records
• many indexes
• missing indexes on foreign keys in child tables. (thank you to @CesarAlvaradoDiaz for mentioning this in the comments)
• deadlocks and blocking
• triggers
• cascade delete (those ten parent records you are deleting could mean millions of child records getting deleted)
• Transaction log needing to grow
• Many Foreign keys to check

So your choices are to find out what is blocking and fix it or run the deletes in off hours when they won't be interfering with the normal production load. You can run the delete in batches (useful if you have triggers, cascade delete, or a large number of records). You can drop and recreate the indexes (best if you can do that in off hours too).

For the record: When you add an import, you are also indicating your dependencies.

You could see quickly what are the dependencies of files (excluding classes of the same namespace).

I solved this issue for myself, I found there's was two files of http-client with different version of other dependent jar files. So there may version were collapsing between libraries files so remove all old/previous libraries files and re-add are jar files from lib folder of this zip file:

Donwload Zip file from here

Map <Integer, Point2D.Double> hm = new HashMap<Integer, Point2D>();
hm.put(1, new Point2D.Double(50, 50));

to access the set cookie do $.cookie("test");

The expression stringexpression = '' yields:

TRUE   .. for '' (or for any string consisting of only spaces with the data type char(n))
NULL   .. for NULL
FALSE .. for anything else

So to check for: "stringexpression is either NULL or empty":

(stringexpression = '') IS NOT FALSE

Or the reverse approach (may be easier to read):

(stringexpression <> '') IS NOT TRUE

Works for any character type including char(n). The manual about comparison operators.

Or use your original expression without trim(), which is costly noise for char(n) (see below), or incorrect for other character types: strings consisting of only spaces would pass as empty string.

coalesce(stringexpression, '') = ''

But the expressions at the top are faster.

Asserting the opposite is even simpler: "stringexpression is neither NULL nor empty":

stringexpression <> ''

About char(n)

This is about the data type char(n), short for: character(n). (char / character are short for char(1) / character(1).) Its use is discouraged in Postgres:

In most situations text or character varying should be used instead.

Do not confuse char(n) with other, useful, character types varchar(n), varchar, text or "char" (with double-quotes).

In char(n) an empty string is not different from any other string consisting of only spaces. All of these are folded to n spaces in char(n) per definition of the type. It follows logically that the above expressions work for char(n) as well - just as much as these (which wouldn't work for other character types):

coalesce(stringexpression, '  ') = '  '
coalesce(stringexpression, '') = '       '

Demo

Empty string equals any string of spaces when cast to char(n):

SELECT ''::char(5) = ''::char(5)     AS eq1
     , ''::char(5) = '  '::char(5)   AS eq2
     , ''::char(5) = '    '::char(5) AS eq3;

Result:

 eq1 | eq2 | eq3
 ----+-----+----
 t   | t   | t

Test for "null or empty string" with char(n):

SELECT stringexpression 
     , stringexpression = ''                   AS base_test
     , (stringexpression = '')  IS NOT FALSE   AS test1
     , (stringexpression <> '') IS NOT TRUE    AS test2
     , coalesce(stringexpression, '') = ''     AS coalesce1
     , coalesce(stringexpression, '  ') = '  ' AS coalesce2
     , coalesce(stringexpression, '') = '  '   AS coalesce3
FROM  (
   VALUES
     ('foo'::char(5))
   , ('')
   , ('   ')                -- not different from '' in char(n)
   , (NULL)
   ) sub(stringexpression);

Result:

In my case I had inherited from the IdentityDbContext correctly (with my own custom types and key defined) but had inadvertantly removed the call to the base class's OnModelCreating:

protected override void OnModelCreating(DbModelBuilder modelBuilder)

    /// Rest of on model creating here.

PS: I had a somewhat similar problem and the above approach solved it.

The easiest thing is to run the program, open the task manager, right-click the process and select properties, here is the full address

it is very simple select the respective view controller in the main story board and check the storyboardID if its present use it in the identidier of give a name and use it.

here my firstone is the storyboardID let vc = self.storyboard?.instantiateViewController(withIdentifier: "firstone") as! tabBarViewController

This is an easy and quick solution when the string value is proper with the comma(,).

But if the string is with the last character with the comma, Which makes a blank array element, and this is also removed extra spaces around it.

"123,234,345,"

So I suggest using push()

var arr = [], str="123,234,345,"
str.split(",").map(function(item){
    if(item.trim()!=''){arr.push(item.trim())}
})

In my case, I've had to click on my project, then go to File > Properties > *servlet name* and click Restart servlet.

This is an old question but as I came across it looking for an answer I thought I will add my answer to this to help others as soon as they got the same problem.

I have a structure like this:

var structure = {
    "root":{
        "name":"Main Level",
        nodes:{
            "node1":{
                "name":"Node 1"  
            },
            "node2":{
                "name":"Node 2"  
            },
            "node3":{
                "name":"Node 3"  
            }
        }
    }
}

Currently, by referencing one of the sub nodes I don't know how to get the parent node with it's name value "Main Level".

Now I introduce a recursive function that travels the structure and adds a parent attribute to each node object and fills it with its parent like so.

var setParent = function(o){
     if(o.nodes != undefined){
          for(n in o.nodes){
              o.nodes[n].parent = o;
              setParent(o.nodes[n]);
          }
     }
}

Then I just call that function and can now get the parent of the current node in this object tree.

setParent(structure.root);

If I now have a reference to the seconds sub node of root, I can just call.

var node2 = structure.root.nodes["node2"];
console.log(node2.parent.name);

and it will output "Main Level".

Hope this helps..

when you bind localhost or 127.0.0.1, it means you can only connect to your service from local.

you cannot bind 10.0.0.1 because it not belong to you, you can only bind ip owned by your computer

To use crypto-js, you need to load core.js then md5.js .

This is in slight response to Joel's comment about making a slighly more optimized version. Instead of returning a random date directly, why not return a generator function which can be called repeatedly to create a random date.

Func<DateTime> RandomDayFunc()
{
    DateTime start = new DateTime(1995, 1, 1); 
    Random gen = new Random(); 
    int range = ((TimeSpan)(DateTime.Today - start)).Days; 
    return () => start.AddDays(gen.Next(range));
}

You can find strings method like "strings".methods You can define string as upcase, downcase, titleize. For Example,

"hii".downcase
"hii".titleize
"hii".upcase

{
    String url = "http://bot.whatismyipaddress.com/";
    String result = null;

    try
    {
        WebClient client = new WebClient();
        result = client.DownloadString(url);
        return result;
    }
    catch (Exception ex) { return "127.0.0.1"; }
}

My app was running on Nexus 5X API 26 x86 (virtual device on emulator) without any errors and then I included a third party AAR. Then it keeps giving this error. I cleaned, rebuilt, checked/unchecked instant run option, wiped the data in AVD, performed cold boot but problem insists. Then I tried the solution found here. he/she says that add splits & abi blocks for 'x86', 'armeabi-v7a' in to module build.gradle file and hallelujah it is clean and fresh again :)

Edit: On this post Driss Bounouar's solution seems to be same. But my emulator was x86 before adding the new AAR and HAXM emulator was already working.

After experimenting for a few hours I figured it out.

  <% @user.errors.full_messages.each do |error_message| %>
    <%= error_message if @user.errors.full_messages.first == error_message %> <br />
  <% end %>
<% end %>

Even better:

<%= @user.errors.full_messages.first if @user.errors.any? %>

In at least in ubuntu 16.10, the default python3 is python3.5. As such, all of the python3-X packages will be installed for python3.5 and not for python3.6.

You can verify this by checking the shebang of pip3:

$ head -n1 $(which pip3)
#!/usr/bin/python3

Fortunately, the pip installed by the python3-pip package is installed into the "shared" /usr/lib/python3/dist-packages such that python3.6 can also take advantage of it.

You can install packages for python3.6 by doing:

python3.6 -m pip install ...

For example:

$ python3.6 -m pip install requests
$ python3.6 -c 'import requests; print(requests.__file__)'
/usr/local/lib/python3.6/dist-packages/requests/__init__.py

Note that the bb.array() doesn't honor the byte-buffers position, and might be even worse if the bytebuffer you are working on is a slice of some other buffer.

I.e.

byte[] test = "Hello World".getBytes("Latin1");
ByteBuffer b1 = ByteBuffer.wrap(test);
byte[] hello = new byte[6];
b1.get(hello); // "Hello "
ByteBuffer b2 = b1.slice(); // position = 0, string = "World"
byte[] tooLong = b2.array(); // Will NOT be "World", but will be "Hello World".
byte[] world = new byte[5];
b2.get(world); // world = "World"

Which might not be what you intend to do.

If you really do not want to copy the byte-array, a work-around could be to use the byte-buffer's arrayOffset() + remaining(), but this only works if the application supports index+length of the byte-buffers it needs.

If you just want to snag the schema and make an empty table out of it, use a false predicate, like so:

SELECT * INTO myNewTable FROM myView WHERE 1=2

Now I need to connect that application from my local computer, but I don't know the JMX port number of the remote computer. Where can I find it? Or, must I restart that application with some VM parameters to specify the port number?

By default JMX does not publish on a port unless you specify the arguments from this page: How to activate JMX...

-Dcom.sun.management.jmxremote # no longer required for JDK6
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false # careful with security implications
-Dcom.sun.management.jmxremote.authenticate=false # careful with security implications

If you are running you should be able to access any of those system properties to see if they have been set:

if (System.getProperty("com.sun.management.jmxremote") == null) {
    System.out.println("JMX remote is disabled");
} else [
    String portString = System.getProperty("com.sun.management.jmxremote.port");
    if (portString != null) {
        System.out.println("JMX running on port "
            + Integer.parseInt(portString));
    }
}

Depending on how the server is connected, you might also have to specify the following parameter. As part of the initial JMX connection, jconsole connects up to the RMI port to determine which port the JMX server is running on. When you initially start up a JMX enabled application, it looks its own hostname to determine what address to return in that initial RMI transaction. If your hostname is not in /etc/hosts or if it is set to an incorrect interface address then you can override it with the following:

-Djava.rmi.server.hostname=<IP address>

As an aside, my SimpleJMX package allows you to define both the JMX server and the RMI port or set them both to the same port. The above port defined with com.sun.management.jmxremote.port is actually the RMI port. This tells the client what port the JMX server is running on.

Unfortunately, no. This feature is not available for facebook albums.

enum Constants
{
    Abc = 1,
    Def = 2,
    Ghi = 3
}

...

int i = (int)Enum.Parse(typeof(Constants), "Def");

Meanwhile I have found the (for me) perfect solution: nexe, which creates a single executable from a Node.js application including all of its modules.

It's the next best thing to an ideal solution.

The syntax for using an alias in an update statement on SQL Server is as follows:

UPDATE Q
SET Q.TITLE = 'TEST'
FROM HOLD_TABLE Q
WHERE Q.ID = 101;

The alias should not be necessary here though.

This is the way to iterate on this array:

foreach($hotels as $row) {
       foreach($row['rooms'] as $k) {
             echo $k['boards']['board_id'];
             echo $k['boards']['price'];
       }
}

You want to iterate on the hotels and the rooms (the ones with numeric indexes), because those seem to be the "collections" in this case. The other arrays only hold and group properties.

An even more minimalistic example:

var linkedResource = new LinkedResource(@"C:\Image.jpg", MediaTypeNames.Image.Jpeg);

// My mail provider would not accept an email with only an image, adding hello so that the content looks less suspicious.
var htmlBody = $"hello<img src=\"cid:{linkedResource.ContentId}\"/>";
var alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(linkedResource);

var mailMessage = new MailMessage
{
    From = new MailAddress("[email protected]"),
    To = { "[email protected]" },
    Subject = "yourSubject",
    AlternateViews = { alternateView }
};

var smtpClient = new SmtpClient();
smtpClient.Send(mailMessage);

In case of SVN servers you have to creating a central repository with all projects. The contents of the repository can be uploaded with the Team/Share command; in case of the Subversive client it automatically runs a commit after the import, so you can upload your files.

This step cannot be circumvented in any way using a centralized version management system such as SVN.

In case you are using Typescript, I'd like to add that you can use the "type predicate" feature. Just should wrap the logical verification in a function that returns x is Promise<any> and you won't need to do typecasts. Below on my example, c is either a promise or one of my types which I want to convert into a promise by calling the c.fetch() method.

export function toPromise(c: Container<any> | Promise<any>): Promise<any> {
    if (c == null) return Promise.resolve();
    return isContainer(c) ? c.fetch() : c;
}

export function isContainer(val: Container<any> | Promise<any>): val is Container<any> {
    return val && (<Container<any>>val).fetch !== undefined;
}

export function isPromise(val: Container<any> | Promise<any>): val is Promise<any> {
    return val && (<Promise<any>>val).then !== undefined;
}

You can set the variable 'fileencodings' in your .vimrc.

This is a list of character encodings considered when starting to edit an existing file. When a file is read, Vim tries to use the first mentioned character encoding. If an error is detected, the next one in the list is tried. When an encoding is found that works, 'fileencoding' is set to it. If all fail, 'fileencoding' is set to an empty string, which means the value of 'encoding' is used.

See :help filencodings

If you often work with e.g. cp1252, you can add it there:

set fileencodings=ucs-bom,utf-8,cp1252,default,latin9

Frames have been deprecated because they caused trouble for url navigation and hyperlinking, because the url would just take to you the index page (with the frameset) and there was no way to specify what was in each of the frame windows. Today, webpages are often generated by server-side technologies such as PHP, ASP.NET, Ruby etc. So instead of using frames, pages can simply be generated by merging a template with content like this:

Template File

<html>
<head>
<title>{insert script variable for title}</title>
</head>

<body>
  <div class="menu">
   {menu items inserted here by server-side scripting}
  </div>
  <div class="main-content">
   {main content inserted here by server-side scripting}
  </div>
</body>
</html>

If you don't have full support for a server-side scripting language, you could also use server-side includes (SSI). This will allow you to do the same thing--i.e. generate a single web page from multiple source documents.

But if you really just want to have a section of your webpage be a separate "window" into which you can load other webpages that are not necessarily located on your own server, you will have to use an iframe.

You could emulate your example like this:

Frames Example

<html>
<head>
  <title>Frames Test</title>
  <style>
   .menu {
      float:left;
      width:20%;
      height:80%;
    }
    .mainContent {
      float:left;
      width:75%;
      height:80%;
    }
  </style>
</head>
<body>
  <iframe class="menu" src="menu.html"></iframe>
  <iframe class="mainContent" src="events.html"></iframe>
</body>
</html>

There are probably better ways to achieve the layout. I've used the CSS float attribute, but you could use tables or other methods as well.

class Countries < ActiveRecord::Base
    self.table_name = "cc"
end

In Rails 3.x this is the way to specify the table name.

You could try lattice:

require(lattice)
x <- 1:100000
y <- 1:100000
xyplot(y~x, scales=list(x = list(log = 10)), type="l")

public class TrackingSystemApplication {

    public static void main(String[] args) {
        SpringApplication.run(TrackingSystemApplication.class, args);
    }

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedOrigins("http://localhost:4200").allowedMethods("PUT", "DELETE",
                        "GET", "POST");
            }
        };
    }

}

Here is a very nifty way.

First format the content such that the column to be compared for uniqueness is a fixed width. One way of doing this is to use awk printf with a field/column width specifier ("%15s").

Now the -f and -w options of uniq can be used to skip preceding fields/columns and to specify the comparison width (column(s) width).

Here are three examples.

In the first example...

1) Temporarily make the column of interest a fixed width greater than or equal to the field's max width.

2) Use -f uniq option to skip the prior columns, and use the -w uniq option to limit the width to the tmp_fixed_width.

3) Remove trailing spaces from the column to "restore" it's width (assuming there were no trailing spaces beforehand).

printf "%s" "$str" \
| awk '{ tmp_fixed_width=15; uniq_col=8; w=tmp_fixed_width-length($uniq_col); for (i=0;i<w;i++) { $uniq_col=$uniq_col" "}; printf "%s\n", $0 }' \
| uniq -f 7 -w 15 \
| awk '{ uniq_col=8; gsub(/ */, "", $uniq_col); printf "%s\n", $0 }'

In the second example...

Create a new uniq column 1. Then remove it after the uniq filter has been applied.

printf "%s" "$str" \
| awk '{ uniq_col_1=4; printf "%15s %s\n", uniq_col_1, $0 }' \
| uniq -f 0 -w 15 \
| awk '{ $1=""; gsub(/^ */, "", $0); printf "%s\n", $0 }'

The third example is the same as the second, but for multiple columns.

printf "%s" "$str" \
| awk '{ uniq_col_1=4; uniq_col_2=8; printf "%5s %15s %s\n", uniq_col_1, uniq_col_2, $0 }' \
| uniq -f 0 -w 5 \
| uniq -f 1 -w 15 \
| awk '{ $1=$2=""; gsub(/^ */, "", $0); printf "%s\n", $0 }'

You can use the DATE_FORMAT function. Here's a page with examples, and the patterns you can use to select different date components.

If you have a button in asp.net design page like "Default.asp" and you want to create CSS file and specified attributes for a button,labels or other controller. Then first of all create a css page

1. Right click on Project
2. Add new item
3. Select StyleSheet

now you have a css page now write these code in your css page(StyleSheet.css)

StyleSheet.css

.mybtnstyle
{
 border:1px solid Red;
 background-color:Red;
 border-style:groove;
 border-top:5px;
 outline-style:dotted;
}

Default.asp

{

  <head> 
  <title> testing.com </title>
 </head>
<body>
 <b>Using Razer<b/>
<form id="form1" runat="server">
 <link id="Link1" rel="stylesheet" runat="server" media="screen" href="Stylesheet1.css" />
 <asp:Button ID="mybtn" class="mybtn" runat="server" Width="339px"/>
 </form>
 </body>
</html>

}

It is good practice to make sure the callback is an actual function before attempting to execute it:

if (callback && typeof(callback) === "function") {

  callback();
}

response[0] is not defined, check if it is defined and then check for its property title.

if(typeof response[0] !== 'undefined' && typeof response[0].title !== 'undefined'){
    //Do something
}

You still need to use their proprietary filters as of IE9 beta 1.

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

PDT eclipse from ZEND has a mac version (PDT all-in-one).

I've been using it for about 3 months and it's pretty solid and has debugging capabilities with xdebug (debug howto) and zend debugger.

I was compiling in x64, just use x86 and it will solve the problem

ssize_t is not included in the standard and isn't portable. size_t should be used when handling the size of objects (there's ptrdiff_t too, for pointer differences).

    var expires = "expires="+d.toUTCString();  
    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}

setCookie('cookieNameToDelete','',0) // this will delete the cookie.

You probably want to change the condition to if ($(this).hasClass('active'))

Also, hasClass and addClass take classnames, not selectors.
Therefore, you shouldn't include a ..

I know this is quite an old one, but I faced similar issue and resolved it in a different way. The actuator-autoconfigure pom somehow was invalid and so it was throwing IllegalStateException. I removed the actuator* dependencies from my maven repo and did a Maven update in eclipse, which then downloaded the correct/valid dependencies and resolved my issue.

from http://www.vmware.com/products/player/faqs.html:

How does VMware Player compare to VMware Workstation? VMware Player enables you to quickly and easily create and run virtual machines. However, VMware Player lacks many powerful features, remote connections to vSphere, drag and drop upload to vSphere, multiple Snapshots and Clones, and much more.

Not being able to revert snapshots it's a big no for me.

I solved the issue by adding this import
More info

from past.builtins import xrange

I see potential shortcomings in many solutions posted above, so I decided to compile my own.
Note: it uses Array.prototype.some, check your browser support.

Solution below considers variable empty if one of the following is true:

1. JS thinks that variable is equal to false, which already covers many things like 0, "", [], and even [""] and [0]
2. Value is null or it's type is 'undefined'
3. It is an empty Object

4. It is an Object/Array consisting only of values that are empty themselves (i.e. broken down to primitives each part of it equals false). Checks drill recursively into Object/Array structure. E.g.

   isEmpty({"": 0}) // true
   isEmpty({"": 1}) // false
   isEmpty([{}, {}])  // true
   isEmpty(["", 0, {0: false}]) //true
   

Function code:

/**
 * Checks if value is empty. Deep-checks arrays and objects
 * Note: isEmpty([]) == true, isEmpty({}) == true, isEmpty([{0:false},"",0]) == true, isEmpty({0:1}) == false
 * @param value
 * @returns {boolean}
 */
function isEmpty(value){
  var isEmptyObject = function(a) {
    if (typeof a.length === 'undefined') { // it's an Object, not an Array
      var hasNonempty = Object.keys(a).some(function nonEmpty(element){
        return !isEmpty(a[element]);
      });
      return hasNonempty ? false : isEmptyObject(Object.keys(a));
    }

    return !a.some(function nonEmpty(element) { // check if array is really not empty as JS thinks
      return !isEmpty(element); // at least one element should be non-empty
    });
  };
  return (
    value == false
    || typeof value === 'undefined'
    || value == null
    || (typeof value === 'object' && isEmptyObject(value))
  );
}

If you use Java and spring MVC you just need to add the following annotation to your method returning your page :

@CrossOrigin(origins = "*")

"*" is to allow your page to be accessible from anywhere. See https://developer.mozilla.org/fr/docs/Web/HTTP/Headers/Access-Control-Allow-Origin for more details about that.

You can use the DOMSubtreeModified event

$(something).bind('DOMSubtreeModified' ...

But this will fire even if the dimensions don't change, and reassigning the position whenever it fires can take a performance hit. In my experience using this method, checking whether the dimensions have changed is less expensive and so you might consider combining the two.

Or if you are directly altering the div (rather than the div being altered by user input in unpredictable ways, like if it is contentEditable), you can simply fire a custom event whenever you do so.

Downside: IE and Opera don't implement this event.

select LAST_LOAD_TIME, ELAPSED_TIME, MODULE, SQL_TEXT elapsed from v$sql
  order by LAST_LOAD_TIME desc

More complicated example (don't forget to delete or to substitute PATTERN):

select * from (
  select LAST_LOAD_TIME, to_char(ELAPSED_TIME/1000, '999,999,999.000') || ' ms' as TIME,
         MODULE, SQL_TEXT from SYS."V_\$SQL"
    where SQL_TEXT like '%PATTERN%'
    order by LAST_LOAD_TIME desc
  ) where ROWNUM <= 5;

As the top answer here is suggesting something wrong (or at least too complicated), I feel this should be updated, although the question is quite old:

When using String resources in Android, you just have to call getString(...) from Java code or use android:text="@string/..." in your layout XML.

Even if you want to use HTML markup in your Strings, you don't have to change a lot:

The only characters that you need to escape in your String resources are:

• double quotation mark: " becomes \"
• single quotation mark: ' becomes \'
• ampersand: & becomes & or &

That means you can add your HTML markup without escaping the tags:

<string name="my_string"><b>Hello World!</b> This is an example.</string>

However, to be sure, you should only use <b>, <i> and <u> as they are listed in the documentation.

If you want to use your HTML strings from XML, just keep on using android:text="@string/...", it will work fine.

The only difference is that, if you want to use your HTML strings from Java code, you have to use getText(...) instead of getString(...) now, as the former keeps the style and the latter will just strip it off.

It's as easy as that. No CDATA, no Html.fromHtml(...).

You will only need Html.fromHtml(...) if you did encode your special characters in HTML markup. Use it with getString(...) then. This can be necessary if you want to pass the String to String.format(...).

This is all described in the docs as well.

Edit:

There is no difference between getText(...) with unescaped HTML (as I've proposed) or CDATA sections and Html.fromHtml(...).

See the following graphic for a comparison:

Simple:

$url = "http://php.net/manual/en/function.preg-match.php";
preg_match("/http:\/\/php\.net(.+)\.php/", $url, $matches);
echo $matches[1];

$matches[0] is your full URL, $matches[1] is the part you want.

See yourself: http://codepad.viper-7.com/hHmwI2

In order to check if your variable is something you could go like:

s='Hello World'
if isinstance(s,str):
#do something here,

The output of isistance will give you a boolean True or False value so you can adjust accordingly. You can check the expected acronym of your value by initially using: type(s) This will return you type 'str' so you can use it in the isistance function.

Generally people pull the official image of Ubuntu/CentOS but they don't realize that these images are minimal and doesn't have any thing on the top of that.

For Ubuntu, this image is built from official rootfs tarballs provided by Canonical. Given that it is a minimal install of Ubuntu, this image only includes the C, C.UTF-8, and POSIX locales by default.

One can install net-tools (includes ifconfig, netstat), ip-utils(includes ping) andy other likes curl etc on container and can create image from container or can write Dockerfile that will install these tool while creating image.

Below is Dockerfile example, while creating image from this it will include these tools:

FROM vkitpro/ubuntu16.04
RUN     apt-get  update -y \
&& apt-get upgrade -y \
&& apt-get install iputils-ping -y \
&& apt-get install net-tools -y \
CMD bash

or launch container from base image and install these utilities on container and then commit to image. docker commit -m "any descriptive message" container_id image_name:lattest

That image will have all thing installed.

Another good one is CEEBot. It teaches C / Java style programming in a fun, robot-programming kind of game. It is aimed at 10-15 year olds, but it is a good one.

Your web app can now take a 'native' screenshot of the client's entire desktop using getUserMedia():

Have a look at this example:

https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/

The client will have to be using chrome (for now) and will need to enable screen capture support under chrome://flags.

You can use alignSelf property on Text component

{ alignSelf : "center" }

I am changing your id to current-month (having no space)

alert($('#current-month').attr('month'));
alert($('#current-month').attr('year'));

You can actually do what Chris Chalmers does in his answer, but you must make sure that HAML doesn't parse the JavaScript. This approach is actually useful when you need to use a different type than text/javascript, which is was I needed to do for MathJax.

You can use the plain filter to keep HAML from parsing the script and throwing an illegal nesting error:

%script{type: "text/x-mathjax-config"}
  :plain
    MathJax.Hub.Config({
      tex2jax: {
        inlineMath: [["$","$"],["\\(","\\)"]]
      }
    });

If you are using any layout page then, move script sections from bottom to head section in layout page. bcz, javascript files should be loaded first. This worked for me

var object = {
    key1 : {
        name : 'xxxxxx',
        value : '100.0'
    },
    key2 : {
        name : 'yyyyyyy',
        value : '200.0'
    },
    key3 : {
        name : 'zzzzzz',
        value : '500.0'
    },
}

If thats how your object looks and you want to loop each name and value then I would try and do something like.

$.each(object,function(key,innerjson){
    /*
        key would be key1,key2,key3
        innerjson would be the name and value **
    */

    //Alerts and logging of the variable.
    console.log(innerjson); //should show you the value    
    alert(innerjson.name); //Should say xxxxxx,yyyyyy,zzzzzzz
});

You would use a service for that in Angular. A service is a function you register with Angular, and that functions job is to return an object which will live until the browser is closed/refreshed. So it's a good place to store state in, and to synchronize that state with the server asynchronously as that state changes.

try this:

public int[] reverse3(int[] nums) {
    int[] reversed = new int[nums.length];
    for (int i=0; i<nums.length; i++) {
        reversed[i] = nums[nums.length - 1 - i];
    }
    return reversed;
}

My input was:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

And the output I got:

12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1

You can use np.logaddexp (which implements the idea in @gg349's answer):

In [33]: d = np.array([[1089, 1093]])

In [34]: e = np.array([[1000, 4443]])

In [35]: log_res = np.logaddexp(-3*d[0,0], -3*d[0,1]) - np.logaddexp(-3*e[0,0], -3*e[0,1])

In [36]: log_res
Out[36]: -266.99999385580668

In [37]: res = exp(log_res)

In [38]: res
Out[38]: 1.1050349147204485e-116

Or you can use scipy.special.logsumexp:

In [52]: from scipy.special import logsumexp

In [53]: res = np.exp(logsumexp(-3*d) - logsumexp(-3*e))

In [54]: res
Out[54]: 1.1050349147204485e-116

Here is a simple example of adding an image to a JFrame:

frame.add(new JLabel(new ImageIcon("Path/To/Your/Image.png")));

Go to java control tab>java control pannel>click security tab>down the security level to medium. Then applet progrramme after 2to 3 security promt it will run.

To style the output to your preferred pretty format, see the man page for git-log.

Example:

git log --pretty=format:"%h; author: %cn; date: %ci; subject:%s" tagA...tagB

In most programming languages, dictionaries are preferred over hashtables

I don't think this is necessarily true, most languages have one or the other, depending on the terminology they prefer.

In C#, however, the clear reason (for me) is that C# HashTables and other members of the System.Collections namespace are largely obsolete. They were present in c# V1.1. They have been replaced from C# 2.0 by the Generic classes in the System.Collections.Generic namespace.

To have unique Categories:

var uniqueCategories =  repository.GetAllProducts()
                                  .Select(p=>p.Category)
                                  .Distinct();

You can either

fig, ax = plt.subplots()  #create figure and axes
candlestick(ax, quotes, ...)

or

candlestick(plt.gca(), quotes) #get the axis when calling the function

The first gives you more flexibility. The second is much easier if candlestick is the only thing you want to plot

What's so confusing about it... getters are functions that are called when you get a property, setters, when you set it. example, if you do

obj.prop = "abc";

You're setting the property prop, if you're using getters/setters, then the setter function will be called, with "abc" as an argument. The setter function definition inside the object would ideally look something like this:

set prop(var) {
   // do stuff with var...
}

I'm not sure how well that is implemented across browsers. It seems Firefox also has an alternative syntax, with double-underscored special ("magic") methods. As usual Internet Explorer does not support any of this.

How about this?

fscanf(file,"%d %d %d %d %d %d %d",&line1_1,&line1_2, &line1_3, &line2_1, &line2_2, &line3_1, &line3_2); 

In this case spaces in fscanf match multiple occurrences of any whitespace until the next token in found.

You could use this snippet -

HttpURLConnection urlConn;
URL mUrl = new URL(url);
urlConn = (HttpURLConnection) mUrl.openConnection();
...
//query is your body
urlConn.addRequestProperty("Content-Type", "application/" + "POST");
if (query != null) {
urlConn.setRequestProperty("Content-Length", Integer.toString(query.length()));
urlConn.getOutputStream().write(query.getBytes("UTF8"));
}

write.csv(t, "t.csv", row.names=FALSE)

From ?write.csv:

row.names: either a logical value indicating whether the row names of
          ‘x’ are to be written along with ‘x’, or a character vector
          of row names to be written.

I'm thinking no. Bookmarks/favorites should be under the control of the user, imagine if any site you visited could insert itself into your bookmarks with just some javascript.

Not at all. Lambda expressions are the one and only point of that annotation.

After some research and testing, I found that I had some misunderstandings about the lifetime of Docker containers. Simply restarting a container doesn't make Docker use a new image, when the image was rebuilt in the meantime. Instead, Docker is fetching the image only before creating the container. So the state after running a container is persistent.

Why removing is required

Therefore, rebuilding and restarting isn't enough. I thought containers works like a service: Stopping the service, do your changes, restart it and they would apply. That was my biggest mistake.

Because containers are permanent, you have to remove them using docker rm <ContainerName> first. After a container is removed, you can't simply start it by docker start. This has to be done using docker run, which itself uses the latest image for creating a new container-instance.

Containers should be as independent as possible

With this knowledge, it's comprehensible why storing data in containers is qualified as bad practice and Docker recommends data volumes/mounting host directorys instead: Since a container has to be destroyed to update applications, the stored data inside would be lost too. This cause extra work to shutdown services, backup data and so on.

So it's a smart solution to exclude those data completely from the container: We don't have to worry about our data, when its stored safely on the host and the container only holds the application itself.

Why -rf may not really help you

The docker run command, has a Clean up switch called -rf. It will stop the behavior of keeping docker containers permanently. Using -rf, Docker will destroy the container after it has been exited. But this switch has two problems:

1. Docker also remove the volumes without a name associated with the container, which may kill your data
2. Using this option, its not possible to run containers in the background using -d switch

While the -rf switch is a good option to save work during development for quick tests, it's less suitable in production. Especially because of the missing option to run a container in the background, which would mostly be required.

How to remove a container

We can bypass those limitations by simply removing the container:

docker rm --force <ContainerName>

The --force (or -f) switch which use SIGKILL on running containers. Instead, you could also stop the container before:

docker stop <ContainerName>
docker rm <ContainerName>

Both are equal. docker stop is also using SIGTERM. But using --force switch will shorten your script, especially when using CI servers: docker stop throws an error if the container is not running. This would cause Jenkins and many other CI servers to consider the build wrongly as failed. To fix this, you have to check first if the container is running as I did in the question (see containerRunning variable).

Full script for rebuilding a Docker container

According to this new knowledge, I fixed my script in the following way:

#!/bin/bash
imageName=xx:my-image
containerName=my-container

docker build -t $imageName -f Dockerfile  .

echo Delete old container...
docker rm -f $containerName

echo Run new container...
docker run -d -p 5000:5000 --name $containerName $imageName

This works perfectly :)

case when isdate(inputdate) = 1 
then convert(datetime, cast(inputdate,datetime2), 103)
else
case when isdate(inputdate) = 0 
then convert(datetime, cast(inputdate,datetime2), 103)

I have this code:

tax = (tax / 100) * price

and then this code:

tax = round((tax / 100) * price, 2)

round worked for me

Kind of an embarrassing occurrence of this error for me, but if it helps the cause...

Make sure you have Ubuntu for desktop, part 1 of this wikihow:

http://www.wikihow.com/Install-Ubuntu-on-VirtualBox

A part I may or may not have skipped, along with part 4 (selecting the Ubuntu ISO as the CD Load)

Nobody's perfect :)

My VirtualHost's ServerName was commented out by default. It worked after uncommenting.

Seems simple enough, but gave me fits. I kept getting "icmp open socket operation not permitted" or else the solutions would hang up if the server was off line. If, however, what you want to know is that the server is alive and you are running a web server on that server, then curl will do the job. If you have ssh and certificates, then ssh and a simple command will suffice. Here is the code:

from easyprocess import EasyProcess # as root: pip install EasyProcess
def ping(ip):
    ping="ssh %s date;exit"%(ip) # test ssh alive or
    ping="curl -IL %s"%(ip)      # test if http alive
    response=len(EasyProcess(ping).call(timeout=2).stdout)
    return response #integer 0 if no response in 2 seconds

Unfortunately the package is not working when you install it from the Package Manager.

According to the documentation of the PropertyFile task, you can append the generated properties to an existing file. You could have a properties file with just the comment line, and have the Ant task append the generated properties.

Java has no map literal, so there's no nice way to do exactly what you're asking.

If you need that type of syntax, consider some Groovy, which is Java-compatible and lets you do:

def map = [name:"Gromit", likes:"cheese", id:1234]

Use user.dir key for get project location using java.

Code:

System.out.println("Present Project Directory : "+ System.getProperty("user.dir"));

OutPut:

Present Project Directory :C:\workspace\MyEclipse 10\examples\MySqlMavenDomain

For displaying all systems properties simply use System.getProperties();

Use Key value in System.getProperty("java.version"); for get output.

Code:

Properties properties = System.getProperties();
Enumeration<Object> enumeration = properties.keys();
for (int i = 0; i < properties.size(); i++) {
    Object obj = enumeration.nextElement();
    System.out.println("Key: "+obj+"\tOutPut= "+System.getProperty(obj.toString()));

To do this, you can use Microsoft's more advanced command-line shell called "Windows PowerShell." It should come standard on the latest versions of Windows, but you can download it from Microsoft if you don't already have it installed.

To get the last five lines in the text file simply read the file using Get-Content, then have Select-Object pick out the last five items/lines for you:

I have pieced together the following that is hopefully simpler and cleaner than some of the existing answers and uses only the AWS CLI and no additional tools.

This code example shows how to get the value of tag 'myTag' for the current EC2 instance:

Using describe-tags:

export AWS_DEFAULT_REGION=us-east-1
instance_id=$(curl -s http://169.254.169.254/latest/meta-data/instance-id)
aws ec2 describe-tags \
  --filters "Name=resource-id,Values=$instance_id" 'Name=key,Values=myTag' \
  --query 'Tags[].Value' --output text

Or, alternatively, using describe-instances:

aws ec2 describe-instances --instance-id $instance_id \
  --query 'Reservations[].Instances[].Tags[?Key==`myTag`].Value' --output text

The $.getJSON() method is shorthand that does not let you specify advanced options like that. To do that, you need to use the full $.ajax() method.

Notice in the documentation at http://api.jquery.com/jQuery.getJSON/:

This is a shorthand Ajax function, which is equivalent to:

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

So just use $.ajax() and provide all the extra parameters you need.

Put the entire script into a template string, with {SERVERNAME} placeholders. Then edit the string using:

SET @SQL_SCRIPT = REPLACE(@TEMPLATE, '{SERVERNAME}', @DBNAME)

and then run it with

EXECUTE (@SQL_SCRIPT)

It's hard to believe that, in the course of three years, nobody noticed that my code doesn't work!

You can't EXEC multiple batches. GO is a batch separator, not a T-SQL statement. It's necessary to build three separate strings, and then to EXEC each one after substitution.

I suppose one could do something "clever" by breaking the single template string into multiple rows by splitting on GO; I've done that in ADO.NET code.

And where did I get the word "SERVERNAME" from?

Here's some code that I just tested (and which works):

DECLARE @DBNAME VARCHAR(255)
SET @DBNAME = 'TestDB'

DECLARE @CREATE_TEMPLATE VARCHAR(MAX)
DECLARE @COMPAT_TEMPLATE VARCHAR(MAX)
DECLARE @RECOVERY_TEMPLATE VARCHAR(MAX)

SET @CREATE_TEMPLATE = 'CREATE DATABASE {DBNAME}'
SET @COMPAT_TEMPLATE='ALTER DATABASE {DBNAME} SET COMPATIBILITY_LEVEL = 90'
SET @RECOVERY_TEMPLATE='ALTER DATABASE {DBNAME} SET RECOVERY SIMPLE'

DECLARE @SQL_SCRIPT VARCHAR(MAX)

SET @SQL_SCRIPT = REPLACE(@CREATE_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@COMPAT_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@RECOVERY_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

function select_option(index)
{
    var optwewant;
    for (opts in $('#span_id').children('select'))
    {
        if (opts.value() = index)
        {
            optwewant = opts;
            break;
        }
    }
    alert (optwewant);
}

A few more relevant things to be noted:

const int a

• must be initialized.
• initialization must be at compile time.

readonly int a

• can use a default value, without initializing.
• initialization can be done at run time (Edit: within constructor only).

For those using raw binary POST upload without encoding overhead you can use:

client:

var xhr = new XMLHttpRequest();
xhr.open("POST", "/api/upload", true);
var blob = new Uint8Array([65,72,79,74]); // or e.g. recorder.getBlob()
xhr.send(blob);

server:

var express = require('express');
var router = express.Router();
var fs = require('fs');

router.use (function(req, res, next) {
  var data='';
  req.setEncoding('binary');
  req.on('data', function(chunk) {
    data += chunk;
  });

  req.on('end', function() {
    req.body = data;
    next();
  });
});

router.post('/api/upload', function(req, res, next) {
  fs.writeFile("binaryFile.png", req.body, 'binary', function(err) {
    res.send("Binary POST successful!");
  });
});

Maybe you should define what you need, as far as I know, you can't run your app as Console or Service with command line, at the same time. Remember that the service is installed and you have to start it in Services Manager, you can create a new application wich starts the service or starts a new process running your console app. But as you wrote

"keep console application as one project"

Once, I was in your position, turning a console application into a service. First you need the template, in case you are working with VS Express Edition. Here is a link where you can have your first steps: C# Windows Service, this was very helpful for me. Then using that template, add your code to the desired events of the service.

To improve you service, there's another thing you can do, but this is not quick and/or easily, is using appdomains, and creating dlls to load/unload. In one you can start a new process with the console app, and in another dll you can just put the functionality the service has to do.

Good luck.
