Use the code below:

<ListView.ItemContainerStyle>
    <Style TargetType="{x:Type ListViewItem}">
        <Setter Property="Background" Value="Transparent" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ListViewItem}">
                    <ContentPresenter />
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ListView.ItemContainerStyle>

In Java there isn't Null values for primitive Data types. If you need to check Null use Integer Class instead of primitive type. You don't need to worry about data type difference. Java converts int primitive type data to Integer. When concerning about the memory Integer takes more memory than int. But the difference of memory allocation, nothing to be considered.

In this case you must use Inter instead of int

Try below snippet and see example for more info,

Integer id;
String name;

//Refer this example
    Integer val = 0;

`

if (val != null){
System.out.println("value is not null");
}

`

Also you can assign Null as below,

val = null;

For MS SQL Server, you can use:

where datetime_column >= Dateadd(Month, Datediff(Month, 0, DATEADD(m, -6,
current_timestamp)), 0)

What you are doing is correct, the problem is somewhere else, e.g. the cookie is being set again somehow on refresh.

It was mentioned in the unset manual's page in 2009:

unset() does just what its name says - unset a variable. It does not force immediate memory freeing. PHP's garbage collector will do it when it see fits - by intention as soon, as those CPU cycles aren't needed anyway, or as late as before the script would run out of memory, whatever occurs first.

If you are doing $whatever = null; then you are rewriting variable's data. You might get memory freed / shrunk faster, but it may steal CPU cycles from the code that truly needs them sooner, resulting in a longer overall execution time.

(Since 2013, that unset man page don't include that section anymore)

Note that until php5.3, if you have two objects in circular reference, such as in a parent-child relationship, calling unset() on the parent object will not free the memory used for the parent reference in the child object. (Nor will the memory be freed when the parent object is garbage-collected.) (bug 33595)

The question "difference between unset and = null" details some differences:

unset($a) also removes $a from the symbol table; for example:

$a = str_repeat('hello world ', 100);
unset($a);
var_dump($a);

Outputs:

Notice: Undefined variable: a in xxx
NULL

But when $a = null is used:

$a = str_repeat('hello world ', 100);
$a = null;
var_dump($a);

Outputs:

NULL

It seems that $a = null is a bit faster than its unset() counterpart: updating a symbol table entry appears to be faster than removing it.

• when you try to use a non-existent (unset) variable, an error will be triggered and the value for the variable expression will be null. (Because, what else should PHP do? Every expression needs to result in some value.)
• A variable with null assigned to it is still a perfectly normal variable though.

int match_position=text.indexOf(match);

You have to set the associatedEmployee on the Vehicle before persisting the Employee.

Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);

newEmployee.setVehicles(vehicles);

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

Found the answer in How to lay out Views in RelativeLayout programmatically?

We should explicitly set id's using setId(). Only then, RIGHT_OF rules make sense.

Another mistake I did is, reusing the layoutparams object between the controls. We should create new object for each control

Edit

A better way to do this is:

1. Create your own less file as a main less file ( like bootstrap.less ).

2. Import all bootstrap less files you need. (in this case, you just need to Import all responsive less files but responsive-1200px-min.less)

3. If you need to modify anything in original bootstrap less file, you just need to write your own less to overwrite bootstrap's less code. (Just remember to put your less code/file after @import { /* bootstrap's less file */ };).

Original

I have the same problem. This is how I fixed it.

Find the media query:

@media (max-width:1200px) ...

Remove it. (I mean the whole thing , not just @media (max-width:1200px))

Since the default width of Bootstrap is 940px, you don't need to do anything.

If you want to have your own max-width, just modify the css rule in the media query that matches your desired width.

There are many ways to update the rows.

When it comes to UPDATE the rows using subqueries, you can use any of these approaches.

1. Approach-1 [Using direct table reference]

UPDATE
  <table1>
SET
  customer=<table2>.customer,
  address=<table2>.address,
  partn=<table2>.partn
FROM
  <table2>
WHERE
  <table1>.address_id=<table2>.address_i;

Explanation: table1 is the table which we want to update, table2 is the table, from which we'll get the value to be replaced/updated. We are using FROM clause, to fetch the table2's data. WHERE clause will help to set the proper data mapping.

2. Approach-2 [Using SubQueries]

UPDATE
  <table1>
SET
  customer=subquery.customer,
  address=subquery.address,
  partn=subquery.partn
FROM
  (
    SELECT
      address_id, customer, address, partn
    FROM  /* big hairy SQL */ ...
  ) AS subquery
WHERE
  dummy.address_id=subquery.address_id;

Explanation: Here we are using subquerie inside the FROM clause, and giving an alias to it. So that it will act like the table.

3. Approach-3 [Using multiple Joined tables]

UPDATE
  <table1>
SET
  customer=<table2>.customer,
  address=<table2>.address,
  partn=<table2>.partn
FROM
  <table2> as t2
  JOIN <table3> as t3
  ON
    t2.id = t3.id
WHERE
  <table1>.address_id=<table2>.address_i;

Explanation: Sometimes we face the situation in that table join is so important to get proper data for the update. To do so, Postgres allows us to Join multiple tables inside the FROM clause.

4. Approach-4 [Using WITH statement]

   • 4.1 [Using simple query]

WITH subquery AS (
    SELECT
      address_id,
      customer,
      address,
      partn
    FROM
      <table1>;
)
UPDATE <table-X>
SET customer = subquery.customer,
    address  = subquery.address,
    partn    = subquery.partn
FROM subquery
WHERE <table-X>.address_id = subquery.address_id;

• 4.2 [Using query with complex JOIN]

WITH subquery AS (
    SELECT address_id, customer, address, partn
    FROM
      <table1> as t1
    JOIN
      <table2> as t2
    ON
      t1.id = t2.id;
    -- You can build as COMPLEX as this query as per your need.
)
UPDATE <table-X>
SET customer = subquery.customer,
    address  = subquery.address,
    partn    = subquery.partn
FROM subquery
WHERE <table-X>.address_id = subquery.address_id;

Explanation: From Postgres 9.1, this(WITH) concept has been introduces. Using that We can make any complex queries and generate desire result. Here we are using this approach to update the table.

I hope, this would be helpful.

Ctrl+Shift+F will do a format of all the code in the page.

Just make sur that the static option is set to false

  @ViewChild('contentPlaceholder', {static: false}) contentPlaceholder: ElementRef;

A good way to test if a string is a correct date is to use the command date:

if date -d "${DATE}" >/dev/null 2>&1
then
  # do what you need to do with your date
else
  echo "${DATE} incorrect date" >&2
  exit 1
fi

from comment: one can use formatting

if [ "2017-01-14" == $(date -d "2017-01-14" '+%Y-%m-%d') ] 

I had the same issue, and I finally found the problem: In the strings.xml, I did not keep the line <string name="app_name">program-name</string> which is present by default when creating a new Android project. I thought it was only used for the program HelloWord, which is the original program.

However, the AndroidManifest.xml refers to this value, hence:

=> A compile error;
=> the R.java isn't updated;
=> ID are not recognized...

UPDATE 
    myTable
SET 
    col = CONCAT( col , "string" )

Could not work it out. The request syntax was correct, but "0 line affected" when executed.

The solution was :

UPDATE 
    myTable 
SET 
    col = CONCAT( myTable.col , "string" )

That one worked.

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

set nocount on

create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)

insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)

declare @PersonID int
set @PersonID = 1

IF EXISTS    
    (
    SELECT 1    
    FROM Timesheet_Hours    
    WHERE Posted_Flag = 1    
        AND Staff_Id = @PersonID    
    )    
    BEGIN
        RAISERROR('Timesheets have already been posted!', 16, 1)
        ROLLBACK TRAN
    END
ELSE
    IF NOT EXISTS
        (
        SELECT 1
        FROM Timesheet_Hours
        WHERE Staff_Id = @PersonID
        )
        BEGIN
            RAISERROR('Default list has not been loaded!', 16, 1)
            ROLLBACK TRAN
        END
    ELSE
        print 'No problems here'

drop table Timesheet_Hours

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

You only need to prefix an if statement with @ if you're not already inside a razor code block.

Edit: You have a couple of things wrong with your code right now.

You're declaring nmb, but never actually doing anything with the value. So you need figure out what that's supposed to actually be doing. In order to fix your code, you need to make a couple of tiny changes:

@if (ViewBag.Articles != null)
{
    int nmb = 0;
    foreach (var item in ViewBag.Articles)
    {
        if (nmb % 3 == 0)
        {
            @:<div class="row"> 
        }

        <a href="@Url.Action("Article", "Programming", new { id = item.id })">
            <div class="tasks">
                <div class="col-md-4">
                    <div class="task important">
                        <h4>@item.Title</h4>
                        <div class="tmeta">
                            <i class="icon-calendar"></i>
                                @item.DateAdded - Pregleda:@item.Click
                            <i class="icon-pushpin"></i> Authorrr
                        </div>
                    </div>
                </div>
            </div>
        </a>
        if (nmb % 3 == 0)
        {
            @:</div>
        }
    }
}

The important part here is the @:. It's a short-hand of <text></text>, which is used to force the razor engine to render text.

One other thing, the HTML standard specifies that a tags can only contain inline elements, and right now, you're putting a div, which is a block-level element, inside an a.

I was able to translate my Crypto object

• Get a copy of php with mcrypt to decrypt the old data. I went to http://php.net/get/php-7.1.12.tar.gz/from/a/mirror, compiled it, then added the ext/mcrypt extension (configure;make;make install). I think I had to add the extenstion=mcrypt.so line to the php.ini as well. A series of scripts to build intermediate versions of the data with all data unencrypted.

• Build a public and private key for openssl

  openssl genrsa -des3 -out pkey.pem 2048
  (set a password)
  openssl rsa -in pkey.pem -out pkey-pub.pem -outform PEM -pubout
  

• To Encrypt (using public key) use openssl_seal. From what I've read, openssl_encrypt using an RSA key is limited to 11 bytes less than the key length (See http://php.net/manual/en/function.openssl-public-encrypt.php comment by Thomas Horsten)

  $pubKey = openssl_get_publickey(file_get_contents('./pkey-pub.pem'));
  openssl_seal($pwd, $sealed, $ekeys, [ $pubKey ]);
  $encryptedPassword = base64_encode($sealed);
  $key = base64_encode($ekeys[0]);
  

You could probably store the raw binary.

• To Decrypt (using private key)

  $passphrase="passphrase here";
  $privKey = openssl_get_privatekey(file_get_contents('./pkey.pem'), $passphrase);
  // I base64_decode() from my db columns
  openssl_open($encryptedPassword, $plain, $key, $privKey);
  echo "<h3>Password=$plain</h3>";
  

P.S. You can't encrypt the empty string ("")

P.P.S. This is for a password database not for user validation.

You need to give the range a -1 step

 for i in range(10,0,-1):
    print i

While @Andre is correct that there are issues with pseudo elements and their support, especially in older (IE) browsers, that support is improving all the time.

As for your question of, are there any issues, I'd say I've not really seen any, although the syntax for the pseudo-element can be a bit tricky, especially when first sussing it out. So:

div#top-level
  declarations: ...
  div.inside
    declarations: ...
    &:first-child
      declarations: ...

which compiles as one would expect:

div#top-level{
  declarations... }
div#top-level div.inside {
  declarations... }
div#top-level div.inside:first-child {
  declarations... }

I haven't seen any documentation on any of this, save for the statement that "sass can do everything that css can do." As always, with Haml and SASS the indentation is everything.

One way is:

select table.* 
from table
join 
(
    select ID, max(Date) as max_dt 
    from table
    group by ID
) t
on table.ID= t.ID and table.Date = t.max_dt 

Note that if you have multiple equally higher dates for same ID, then you will get all those rows in result

var text = html.replace(/<\/?("[^"]*"|'[^']*'|[^>])*(>|$)/g, "");

This is a regex version, which is more resilient to malformed HTML, like:

Unclosed tags

Some text <img

"<", ">" inside tag attributes

Some text <img alt="x > y">

Newlines

Some <a href="http://google.com">

The code

var html = '<br>This <img alt="a>b" \r\n src="a_b.gif" />is > \nmy<>< > <a>"text"</a'
var text = html.replace(/<\/?("[^"]*"|'[^']*'|[^>])*(>|$)/g, "");

Since version 4.14 of Linux kernel, vfs_read and vfs_write functions are no longer exported for use in modules. Instead, functions exclusively for kernel's file access are provided:

# Read the file from the kernel space.
ssize_t kernel_read(struct file *file, void *buf, size_t count, loff_t *pos);

# Write the file from the kernel space.
ssize_t kernel_write(struct file *file, const void *buf, size_t count,
            loff_t *pos);

Also, filp_open no longer accepts user-space string, so it can be used for kernel access directly (without dance with set_fs).

From official documentation, FailedPreconditionError

This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.

In your case the error even explains what variable was not initialized: Attempting to use uninitialized value Variable_1. One of the TF tutorials explains a lot about variables, their creation/initialization/saving/loading

Basically to initialize the variable you have 3 options:

• initialize all global variables with tf.global_variables_initializer()
• initialize variables you care about with tf.variables_initializer(list_of_vars). Notice that you can use this function to mimic global_variable_initializer: tf.variable_initializers(tf.global_variables())
• initialize only one variable with var_name.initializer

I almost always use the first approach. Remember you should put it inside a session run. So you will get something like this:

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())

If your are curious about more information about variables, read this documentation to know how to report_uninitialized_variables and check is_variable_initialized.

Having the following XML:

<node>Text1<subnode/>text2</node> 

How do I select either the first or the second text node via XPath?

Use:

/node/text()

This selects all text-node children of the top element (named "node") of the XML document.

/node/text()[1]

This selects the first text-node child of the top element (named "node") of the XML document.

/node/text()[2]

This selects the second text-node child of the top element (named "node") of the XML document.

/node/text()[someInteger]

This selects the someInteger-th text-node child of the top element (named "node") of the XML document. It is equivalent to the following XPath expression:

/node/text()[position() = someInteger]

Applying the recursive function on numpy arrays will be faster than the current answer.

df = pd.DataFrame(np.repeat(np.arange(2, 6),3).reshape(4,3), columns=['A', 'B', 'D'])
new = [df.D.values[0]]
for i in range(1, len(df.index)):
    new.append(new[i-1]*df.A.values[i]+df.B.values[i])
df['C'] = new

Output

      A  B  D    C
   0  1  1  1    1
   1  2  2  2    4
   2  3  3  3   15
   3  4  4  4   64
   4  5  5  5  325

can also use a CSS class to define the range of radio buttons and then use the following to determine the value

$('.radio_check:checked').val()

# To support matches from the beginning, not any matches:

items = ['a', 'ab', 'abc', 'bac']
prefix = 'ab'

filter(lambda x: x.startswith(prefix), items)

Properties in your object are value types and you can use the shallow copy in such situation like that:

obj myobj2 = (obj)myobj.MemberwiseClone();

But in other situations, like if any members are reference types, then you need Deep Copy. You can get a deep copy of an object using Serialization and Deserialization techniques with the help of BinaryFormatter class:

public static T DeepCopy<T>(T other)
{
    using (MemoryStream ms = new MemoryStream())
    {
        BinaryFormatter formatter = new BinaryFormatter();
        formatter.Context = new StreamingContext(StreamingContextStates.Clone);
        formatter.Serialize(ms, other);
        ms.Position = 0;
        return (T)formatter.Deserialize(ms);
    }
}

The purpose of setting StreamingContext: We can introduce special serialization and deserialization logic to our code with the help of either implementing ISerializable interface or using built-in attributes like OnDeserialized, OnDeserializing, OnSerializing, OnSerialized. In all cases StreamingContext will be passed as an argument to the methods(and to the special constructor in case of ISerializable interface). With setting ContextState to Clone, we are just giving hint to that method about the purpose of the serialization.

Additional Info: (you can also read this article from MSDN)

Shallow copying is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed; for a reference type, the reference is copied but the referred object is not; therefore the original object and its clone refer to the same object.

Deep copy is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed. If a field is a reference type, a new copy of the referred object is performed.

angular.module('elnApp')
.directive('jqdatepicker', function() {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function(scope, element, attrs, ctrl) {
            $(element).datepicker({
                dateFormat: 'dd.mm.yy',
                onSelect: function(date) {
                    ctrl.$setViewValue(date);
                    ctrl.$render();
                    scope.$apply();
                }
            });
        }
    };

Lodash has a "map" function that works just like jQuerys:

var myArr =  [{ name: "john", age:23 },_x000D_
              { name: "john", age:43 },_x000D_
              { name: "jimi", age:10 },_x000D_
              { name: "bobi", age:67 }];_x000D_
_x000D_
var johns = _.map(myArr, function(o) {_x000D_
    if (o.name == "john") return o;_x000D_
});_x000D_
_x000D_
// Remove undefines from the array_x000D_
johns = _.without(johns, undefined)

It is possible to reference an intellij 'Path Variable' in an intellij 'Run Configuration'.

In 'Path Variables' create a variable for example ANALYTICS_VERSION.

In a 'Run Configuration' under 'Environment Variables' add for example the following:

ANALYTICS_LOAD_LOCATION=$MAVEN_REPOSITORY$\com\my\company\analytics\$ANALYTICS_VERSION$\bin

To answer the original question you would need to add an APP_HOME environment variable to your run configuration which references the path variable:

APP_HOME=$APP_HOME$

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

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

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

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

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

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

Normally that error occurs when a } was missed somewhere in the code, for example:

void mi_start_curr_serv(void){
    #if 0
    //stmt
    #endif

would fail with this error due to the missing } at the end of the function. The code you posted doesn't have this error, so it is likely coming from some other part of your source.

Adding up to other answers you need to export the class to use in a different class. This is a typescript version of it.

//Constants.tsx
const DEBUG: boolean = true;

export class Constants {
  static get DEBUG(): boolean {
    return DEBUG;
  }
}

//Anotherclass.tsx
import { Constants } from "Constants";

if (Constants.DEBUG) {
  console.log("debug mode")
}

Look here: http://en.cppreference.com/w/cpp/algorithm/sort.

It says:

template< class RandomIt, class Compare >
void sort( RandomIt first, RandomIt last, Compare comp );

• comp - comparison function which returns ?true if the first argument is less than the second. The signature of the comparison function should be equivalent to the following: bool cmp(const Type1 &a, const Type2 &b);

Also, here's an example of how you can use std::sort using a custom C++14 polymorphic lambda:

std::sort(std::begin(container), std::end(container),
          [] (const auto& lhs, const auto& rhs) {
    return lhs.first < rhs.first;
});

Try:

    if (textBox1.Text == "" || textBox2.Text == "")
    {
        // do something..
    }

Instead of:

    if (textBox1.Text == string.Empty || textBox2.Text == string.Empty)
    {
        // do something..
    }

Because string.Empty is different than - "".

For anyone trying the answers to this question to get the stdout from a Python script note that Python buffers its stdout, and therefore it may take a while to see the stdout.

This can be rectified by adding the following after each stdout write in the target script:

sys.stdout.flush()

I was facing the same issue and in my case compiler compliance level was selected as 14 in my eclipse settings. In order to fix it, I changed it to the version of JDK on my machine i.e 1.8 and recompiled the project.

Use BigDecimal, not double

The Answer by adatapost is right about using String::split but wrong about using double to represent your longitude-latitude values. The float/Float and double/Double types use floating-point technology which trades away accuracy for speed of execution.

Instead use BigDecimal to correctly represent your lat-long values.

Use Apache Commons CSV library

Also, best to let a library such as Apache Commons CSV perform the chore of reading and writing CSV or Tab-delimited files.

Example app

Here is a complete example app using that Commons CSV library. This app writes then reads a data file. It uses String::split for the writing. And the app uses BigDecimal objects to represent your lat-long values.

package work.basil.example;

For the pull to refresh i am using

DGElasticPullToRefresh

https://github.com/gontovnik/DGElasticPullToRefresh

Installation

pod 'DGElasticPullToRefresh'

import DGElasticPullToRefresh

and put this function into your swift file and call this funtion from your

override func viewWillAppear(_ animated: Bool)

     func Refresher() {
      let loadingView = DGElasticPullToRefreshLoadingViewCircle()
      loadingView.tintColor = UIColor(red: 255.0/255.0, green: 255.0/255.0, blue: 255.0/255.0, alpha: 1.0)
      self.table.dg_addPullToRefreshWithActionHandler({ [weak self] () -> Void in

          //Completion block you can perfrom your code here.

           print("Stack Overflow")

           self?.table.dg_stopLoading()
           }, loadingView: loadingView)
      self.table.dg_setPullToRefreshFillColor(UIColor(red: 255.0/255.0, green: 57.0/255.0, blue: 66.0/255.0, alpha: 1))
      self.table.dg_setPullToRefreshBackgroundColor(self.table.backgroundColor!)
 }

And dont forget to remove reference while view will get dissapear

to remove pull to refresh put this code in to your

override func viewDidDisappear(_ animated: Bool)

override func viewDidDisappear(_ animated: Bool) {
      table.dg_removePullToRefresh()

 }

And it will looks like

Happy coding :)

List<string> mylist = new List<string>(new string[] { "element1", "element2", "element3" });

I am answering this question late but hope it will help the other candidate facing same problem.

I have used two methods to load thumbnail for videos list the first was

    Bitmap bmThumbnail;
    bmThumbnail = ThumbnailUtils.createVideoThumbnail(FILE_PATH
                    + videoList.get(position),
            MediaStore.Video.Thumbnails.MINI_KIND);

    if (bmThumbnail != null) {
        Log.d("VideoAdapter","video thumbnail found");
        holder.imgVideo.setImageBitmap(bmThumbnail);
    } else {
        Log.d("VideoAdapter","video thumbnail not found");
    }

its look good but there was a problem with this solution because when i scroll video list it will freeze some time due to its large processing.

so after this i found another solution which works perfectly by using Glide Library.

 Glide
            .with( mContext )
            .load( Uri.fromFile( new File( FILE_PATH+videoList.get(position) ) ) )
            .into( holder.imgVideo );

I recommended the later solution for showing thumbnail with video list . thanks

You can use show innodb status (or show engine innodb status for newer versions of mysql) to get a list of all the actions currently pending inside the InnoDB engine. Buried in the wall of output will be the transactions, and what internal process ID they're running under.

You won't be able to force a commit or rollback of those transactions, but you CAN kill the MySQL process running them, which does essentially boil down to a rollback. It kills the processes' connection and causes MySQL to clean up the mess its left.

Here's what you'd want to look for:

------------
TRANSACTIONS
------------
Trx id counter 0 140151
Purge done for trx's n:o < 0 134992 undo n:o < 0 0
History list length 10
LIST OF TRANSACTIONS FOR EACH SESSION:
---TRANSACTION 0 0, not started, process no 17004, OS thread id 140621902116624
MySQL thread id 10594, query id 10269885 localhost marc
show innodb status

In this case, there's just one connection to the InnoDB engine right now (my login, running the show query). If that line were an actual connection/stuck transaction you'd want to terminate, you'd then do a kill 10594.

I had this problem and it took me nearly 2 days to resolve...

I had moved my SDK location, due to the system drive being full, and it seems that someone, somewhere at Android Studio central has hard-coded the path to the HaxM driver installer. As my HamX driver was out of date, the emulator wouldn't start.

Solution: navigate to [your sdk location]\extras\intel\Hardware_Accelerated_Execution_Manager and run the intelhaxm-android.exe installer to update yourself to the latest driver.

>>> import datetime
>>> d = datetime.datetime.strptime('2011-06-09', '%Y-%m-%d')
>>> d.strftime('%b %d,%Y')
'Jun 09,2011'

In pre-2.5 Python, you can replace datetime.strptime with time.strptime, like so (untested): datetime.datetime(*(time.strptime('2011-06-09', '%Y-%m-%d')[0:6]))

You can define style rules which only apply to specific elements inside your div with id divContainer like this:

#divContainer input { ... }
#divContainer input[type="radio"] { ... }
#divContainer input[type="text"] { ... }
/* etc */

The PATH is for current user, instead you can add a CLASSPATH and below link would help you more PATH and CLASSPATH

The compiler is saying that annualRate will not have a value if the CreditPlan is not recognised.

When creating the local variables ( annualRate, monthlyCharge, and lateFee) assign a default value (0) to them.

Also, you should display an error if the credit plan is unknown.

The key lies in the differences between references and instances and what the reference can promise and what the instance can really do.

ArrayList<A> a = new ArrayList<A>();

Here a is a reference to an instance of a specific type - exactly an array list of As. More explicitly, a is a reference to an array list that will accept As and will produce As. new ArrayList<A>() is an instance of an array list of As, that is, an array list that will accept As and will produce As.

ArrayList<Integer> a = new ArrayList<Number>(); 

Here, a is a reference to exactly an array list of Integers, i.e. exactly an array list that can accept Integers and will produce Integers. It cannot point to an array list of Numbers. That array list of Numbers can not meet all the promises of ArrayList<Integer> a (i.e. an array list of Numbers may produce objects that are not Integers, even though its empty right then).

ArrayList<Number> a = new ArrayList<Integer>(); 

Here, declaration of a says that a will refer to exactly an array list of Numbers, that is, exactly an array list that will accept Numbers and will produce Numbers. It cannot point to an array list of Integers, because the type declaration of a says that a can accept any Number, but that array list of Integers cannot accept just any Number, it can only accept Integers.

ArrayList<? extends Object> a= new ArrayList<Object>();

Here a is a (generic) reference to a family of types rather than a reference to a specific type. It can point to any list that is member of that family. However, the trade-off for this nice flexible reference is that they cannot promise all of the functionality that it could if it were a type-specific reference (e.g. non-generic). In this case, a is a reference to an array list that will produce Objects. But, unlike a type-specific list reference, this a reference cannot accept any Object. (i.e. not every member of the family of types that a can point to can accept any Object, e.g. an array list of Integers can only accept Integers.)

ArrayList<? super Integer> a = new ArrayList<Number>();

Again, a is a reference to a family of types (rather than a single specific type). Since the wildcard uses super, this list reference can accept Integers, but it cannot produce Integers. Said another way, we know that any and every member of the family of types that a can point to can accept an Integer. However, not every member of that family can produce Integers.

PECS - Producer extends, Consumer super - This mnemonic helps you remember that using extends means the generic type can produce the specific type (but cannot accept it). Using super means the generic type can consume (accept) the specific type (but cannot produce it).

ArrayList<ArrayList<?>> a

An array list that holds references to any list that is a member of a family of array lists types.

= new ArrayList<ArrayList<?>>(); // correct

An instance of an array list that holds references to any list that is a member of a family of array lists types.

ArrayList<?> a

An reference to any array list (a member of the family of array list types).

= new ArrayList<?>()

ArrayList<?> refers to any type from a family of array list types, but you can only instantiate a specific type.

See also How can I add to List<? extends Number> data structures?

In the new ES2015 standard for JavaScript (formerly called ES6), objects can be created with computed keys: Object Initializer spec.

The syntax is:

var obj = {
  [myKey]: value,
}

If applied to the OP's scenario, it would turn into:

stuff = function (thing, callback) {
  var inputs  = $('div.quantity > input').map(function(){
    return {
      [this.attr('name')]: this.attr('value'),
    };
  }) 

  callback(null, inputs);
}

Note: A transpiler is still required for browser compatiblity.

Using Babel or Google's traceur, it is possible to use this syntax today.

In earlier JavaScript specifications (ES5 and below), the key in an object literal is always interpreted literally, as a string.

To use a "dynamic" key, you have to use bracket notation:

var obj = {};
obj[myKey] = value;

In your case:

stuff = function (thing, callback) {
  var inputs  = $('div.quantity > input').map(function(){
    var key   = this.attr('name')
     ,  value = this.attr('value')
     ,  ret   = {};

     ret[key] = value;
     return ret;
  }) 

  callback(null, inputs);
}

You templatize your class based on an 'unsigned int'.

Example:

template <unsigned int N>
class MyArray
{
    public:
    private:
        double    data[N]; // Use N as the size of the array
};

int main()
{
    MyArray<2>     a1;
    MyArray<2>     a2;

    MyArray<4>     b1;

    a1 = a2;  // OK The arrays are the same size.
    a1 = b1;  // FAIL because the size of the array is part of the
              //      template and thus the type, a1 and b1 are different types.
              //      Thus this is a COMPILE time failure.
 }

If you're just using a vanilla form (not a ModelForm), you can set a Field initial value ( https://docs.djangoproject.com/en/2.2/ref/forms/fields/#django.forms.Field.initial ) like

class MyForm(forms.Form):
    my_field = forms.BooleanField(initial=True)

If you're using a ModelForm, you can set a default value on the model field ( https://docs.djangoproject.com/en/2.2/ref/models/fields/#default ), which will apply to the resulting ModelForm, like

class MyModel(models.Model):
    my_field = models.BooleanField(default=True)

Finally, if you want to dynamically choose at runtime whether or not your field will be selected by default, you can use the initial parameter to the form when you initialize it:

form = MyForm(initial={'my_field':True})

It moves table down because there is no much space, try to decrease/increase width of certain elements so that it finds some space and does not push the table down. Also you may want to use absolute positioning to position the div at exactly the place you want, for example:

<style>
 #div_id
 {
   position:absolute;
   top:100px; /* set top value */
   left:100px; /* set left value */
   width:100px;  /* set width value */
 }
</style>

If you want to appear it over something, you also need to give it z-index, so it might look like this:

<style>
 #div_id
 {
   position:absolute;
   z-index:999;
   top:100px; /* set top value */
   left:100px; /* set left value */
   width:100px;  /* set width value */
 }
</style>

The primary purpose of AF_INET was to allow for other possible network protocols or address families (AF is for address family; PF_INET is for the (IPv4) internet protocol family). For example, there probably are a few Netware SPX/IPX networks around still; there were other network systems like DECNet, StarLAN and SNA, not to mention the ill-begotten ISO OSI (Open Systems Interconnection), and these did not necessarily use the now ubiquitous IP address to identify the peer host in network connections.

The ubiquitous alternative to AF_INET (which, in retrospect, should have been named AF_INET4) is AF_INET6, for the IPv6 address family. IPv4 uses 32-bit addresses; IPv6 uses 128-bit addresses.

You may see some other values - but they are unusual. It is there to allow for alternatives and future directions. The sockets interface is actually very general indeed - which is one of the reasons it has thrived where other networking interfaces have withered.

Life has (mostly) gotten simpler - be grateful.

Java-8 solution using Stream API:

A. When timeStarted and timeEnded are public (as mentioned in the requirement) and therefore do not (need to) have public getter methods:

List<ActiveAlarm> sorted = 
    list.stream()
        .sorted(Comparator.comparingLong((ActiveAlarm alarm) -> alarm.timeStarted)
                        .thenComparingLong((ActiveAlarm alarm) -> alarm.timeEnded))
        .collect(Collectors.toList());

B. When timeStarted and timeEnded have public getter methods:

List<ActiveAlarm> sorted = 
    list.stream()
        .sorted(Comparator.comparingLong(ActiveAlarm::getTimeStarted)
                        .thenComparingLong(ActiveAlarm::getTimeEnded))
        .collect(Collectors.toList());

If you want to sort the original list itself:

A. When timeStarted and timeEnded are public (as mentioned in the requirement) and therefore do not (need to) have public getter methods:

list.sort(Comparator.comparingLong((ActiveAlarm alarm) -> alarm.timeStarted)
                    .thenComparingLong((ActiveAlarm alarm) -> alarm.timeEnded));

B. When timeStarted and timeEnded have public getter methods:

list.sort(Comparator.comparingLong(ActiveAlarm::getTimeStarted)
                    .thenComparingLong(ActiveAlarm::getTimeEnded));

Unlike the CMD.EXE CHDIR or CD command, the PowerShell Set-Location cmdlet will change drive and directory, both. Get-Help Set-Location -Full will get you more detailed information on Set-Location, but the basic usage would be

PS C:\> Set-Location -Path Q:\MyDir

PS Q:\MyDir> 

By default in PowerShell, CD and CHDIR are alias for Set-Location.

(Asad reminded me in the comments that if the path contains spaces, it must be enclosed in quotes.)

With ES6 you can simply do:

 for(const element of Results) {
      element.Active = "false";
 }

I solved! deactivate UAC with msconfig before to install xampp

Perl versions 5.10 and later support subsidiary vertical and horizontal character classes, \v and \h, as well as the generic whitespace character class \s

The cleanest solution is to use the horizontal whitespace character class \h. This will match tab and space from the ASCII set, non-breaking space from extended ASCII, or any of these Unicode characters

U+0009 CHARACTER TABULATION
U+0020 SPACE
U+00A0 NO-BREAK SPACE (not matched by \s)

U+1680 OGHAM SPACE MARK
U+2000 EN QUAD
U+2001 EM QUAD
U+2002 EN SPACE
U+2003 EM SPACE
U+2004 THREE-PER-EM SPACE
U+2005 FOUR-PER-EM SPACE
U+2006 SIX-PER-EM SPACE
U+2007 FIGURE SPACE
U+2008 PUNCTUATION SPACE
U+2009 THIN SPACE
U+200A HAIR SPACE
U+202F NARROW NO-BREAK SPACE
U+205F MEDIUM MATHEMATICAL SPACE
U+3000 IDEOGRAPHIC SPACE

The vertical space pattern \v is less useful, but matches these characters

U+000A LINE FEED
U+000B LINE TABULATION
U+000C FORM FEED
U+000D CARRIAGE RETURN
U+0085 NEXT LINE (not matched by \s)

U+2028 LINE SEPARATOR
U+2029 PARAGRAPH SEPARATOR

There are seven vertical whitespace characters which match \v and eighteen horizontal ones which match \h. \s matches twenty-three characters

All whitespace characters are either vertical or horizontal with no overlap, but they are not proper subsets because \h also matches U+00A0 NO-BREAK SPACE, and \v also matches U+0085 NEXT LINE, neither of which are matched by \s

Except for techniques mentioned above, with some effort, you can run maven through proxy using jproxyloader library (there is example on page how to do this: http://jproxyloader.sourceforge.net/). This allows set up socks proxy only for downloading artifacts.

In solution mentioned by duanni (setting -DsocksProxyHost) there is one problem. If you have integration tests running against local database (or another tests connecting to url which should not go via proxy). These tests will stop working because connections to database will also be directed to proxy. With help of jProxyLoader you can set up proxy only for nexus host. Additionally if you want you can pass connections to database through another proxy.

boolarr.sum(axis=1 or axis=0)

axis = 1 will output number of trues in a row and axis = 0 will count number of trues in columns so

boolarr[[true,true,true],[false,false,true]]
print(boolarr.sum(axis=1))

will be (3,1)

I tackled this problem a few years ago and uploaded my solution to github as https://github.com/rossturner/HTML5-ImageUploader

robertc's answer uses the solution proposed in the Mozilla Hacks blog post, however I found this gave really poor image quality when resizing to a scale that was not 2:1 (or a multiple thereof). I started experimenting with different image resizing algorithms, although most ended up being quite slow or else were not great in quality either.

Finally I came up with a solution which I believe executes quickly and has pretty good performance too - as the Mozilla solution of copying from 1 canvas to another works quickly and without loss of image quality at a 2:1 ratio, given a target of x pixels wide and y pixels tall, I use this canvas resizing method until the image is between x and 2 x, and y and 2 y. At this point I then turn to algorithmic image resizing for the final "step" of resizing down to the target size. After trying several different algorithms I settled on bilinear interpolation taken from a blog which is not online anymore but accessible via the Internet Archive, which gives good results, here's the applicable code:

ImageUploader.prototype.scaleImage = function(img, completionCallback) {
    var canvas = document.createElement('canvas');
    canvas.width = img.width;
    canvas.height = img.height;
    canvas.getContext('2d').drawImage(img, 0, 0, canvas.width, canvas.height);

    while (canvas.width >= (2 * this.config.maxWidth)) {
        canvas = this.getHalfScaleCanvas(canvas);
    }

    if (canvas.width > this.config.maxWidth) {
        canvas = this.scaleCanvasWithAlgorithm(canvas);
    }

    var imageData = canvas.toDataURL('image/jpeg', this.config.quality);
    this.performUpload(imageData, completionCallback);
};

ImageUploader.prototype.scaleCanvasWithAlgorithm = function(canvas) {
    var scaledCanvas = document.createElement('canvas');

    var scale = this.config.maxWidth / canvas.width;

    scaledCanvas.width = canvas.width * scale;
    scaledCanvas.height = canvas.height * scale;

    var srcImgData = canvas.getContext('2d').getImageData(0, 0, canvas.width, canvas.height);
    var destImgData = scaledCanvas.getContext('2d').createImageData(scaledCanvas.width, scaledCanvas.height);

    this.applyBilinearInterpolation(srcImgData, destImgData, scale);

    scaledCanvas.getContext('2d').putImageData(destImgData, 0, 0);

    return scaledCanvas;
};

ImageUploader.prototype.getHalfScaleCanvas = function(canvas) {
    var halfCanvas = document.createElement('canvas');
    halfCanvas.width = canvas.width / 2;
    halfCanvas.height = canvas.height / 2;

    halfCanvas.getContext('2d').drawImage(canvas, 0, 0, halfCanvas.width, halfCanvas.height);

    return halfCanvas;

This scales an image down to a width of config.maxWidth, maintaining the original aspect ratio. At the time of development this worked on iPad/iPhone Safari in addition to major desktop browsers (IE9+, Firefox, Chrome) so I expect it will still be compatible given the broader uptake of HTML5 today. Note that the canvas.toDataURL() call takes a mime type and image quality which will allow you to control the quality and output file format (potentially different to input if you wish).

The only point this doesn't cover is maintaining the orientation information, without knowledge of this metadata the image is resized and saved as-is, losing any metadata within the image for orientation meaning that images taken on a tablet device "upside down" were rendered as such, although they would have been flipped in the device's camera viewfinder. If this is a concern, this blog post has a good guide and code examples on how to accomplish this, which I'm sure could be integrated to the above code.

Try changing from windows authentication to mixed mode

You can use Date.UTC method to get the time stamp at the UTC timezone.

Usage:

var now = new Date;
var utc_timestamp = Date.UTC(now.getUTCFullYear(),now.getUTCMonth(), now.getUTCDate() , 
      now.getUTCHours(), now.getUTCMinutes(), now.getUTCSeconds(), now.getUTCMilliseconds());

Live demo here http://jsfiddle.net/naryad/uU7FH/1/

for windows use & in between command also. Like,

  "scripts": {
    "start": "SET NODE_ENV=development & nodemon app/app.js",
  }

Got to

Change the version of the below mentioned distribution (gradle-5.6.4-bin.zip)

distributionUrl=https://services.gradle.org/distributions/gradle-5.6.4-bin.zip

This worked for me (Select2 4.0.4):

$(document).on('change', 'select#your_id', function(e) {
    // your code
    console.log('this.value', this.value);
});

DialogFragment is basically a Fragment that can be used as a dialog.

Using DialogFragment over Dialog due to the following reasons:

• DialogFragment is automatically re-created after configuration changes and save & restore flow
• DialogFragment inherits full Fragment’s lifecycle
• No more IllegalStateExceptions and leaked window crashes. This was pretty common when the activity was destroyed with the Alert Dialog still there.

There's a note on top of the docs:

Note: The Google Web Search API has been officially deprecated as of November 1, 2010. It will continue to work as per our deprecation policy, but the number of requests you may make per day will be limited. Therefore, we encourage you to move to the new Custom Search API.

The deprecation policy says that they will continue to run the API for 3 years. So if you already have an application that uses the old API, you don't have to rush to change things just yet. If you're writing a new application, use the Custom Search API. See my answer here for how to do this in Python, but the idea's the same for any language.

I have a trick for doing this!

I came up with this method because while on the CLI, it's not possible to use the methods provided in the other answers here and it had always bugged me.

I call this the "Do Until Break" or "Infinite" Loop:

Basic Example

FOR /L %L IN (0,0,1) DO @(
 ECHO. Counter always 0, See "%L" = "0" - Waiting a split second&ping -n 1 127.0.0.1>NUL )

This is truly an infinite loop!

This is useful for monitoring something in a CMD window, and allows you to use CTRL+C to break it when you're done.

Want to Have a counter?

Either use SET /A OR You can modify the FOR /L Loop to do the counting and still be infinite (Note, BOTH of these methods have a 32bit integer overflow)

SET /A Method:

FOR /L %L IN (0,0,1) DO @(
 SET /A "#+=1"&ECHO. L Still equals 0, See "%L = 0"!  - Waiting a split second &ping -n 1 127.0.0.1>NUL  )

Native FOR /L Counter:

FOR /L %L IN (-2147483648,1,2147483648) DO @(
 ECHO.Current value of L: %L - Waiting a split second &ping -n 1 127.0.0.1>NUL  )

Counting Sets of 4294967295 and Showing Current Value of L:

FOR /L %L IN (1,1,2147483648) DO @(
 (
  IF %L EQU 0 SET /A "#+=1">NUL
 )&SET /A "#+=0"&ECHO. Sets of 4294967295 - Current value of L: %L - Waiting a split second &ping -n 1 127.0.0.1>NUL )

However, what if:

• You're interested in reviewing the output of the monitor, and concerned that I will pass the 9999 line buffer limit before I check it after it has completed.
• You'd like to take some additional actions once the Thing I am monitoring is finished.

For this, I determined how to use a couple methods to break the FOR Loop prematurely effectively turning it into a "DO WHILE" or "DO UNTIL" Loop, which is otherwise sorely lacking in CMD.

NOTE: Most of the time a loop will continue to iterate past the condition you checked for, often this is a wanted behavior, but not in our case.

Turn the "infinite Loop" into a "DO WHILE" / "DO UNTIL" Loop

UPDATE: Due to wanting to use this code in CMD Scripts (and have them persist!) as well as CLI, and on thinking if there might be a "more Correct" method to achieve this I recommend using the New method!

New Method (Can be used inside CMD Scripts without exiting the script):

FOR /F %%A IN ('
  CMD /C "FOR /L %%L IN (0,1,2147483648) DO @( ECHO.%%L & IF /I %%L EQU 10 ( exit /b  ) )"
') DO @(
  ECHO %%~A
)

At CLI:

FOR /F %A IN ('
  CMD /C "FOR /L %L IN (0,1,2147483648) DO @( ECHO.%L & IF /I %L EQU 10 ( exit /b  ) )"
') DO @(
  ECHO %~A
)

Original Method (Will work on CLI just fine, but will kill a script.)

FOR /L %L IN (0,1,2147483648) DO @(
  ECHO.Current value of L: %L - Waiting a split second &ping -n 1 127.0.0.1>NUL&(
    IF /I %L EQU 10 (
      ECHO.Breaking the Loop! Because We have matched the condition!&DIR >&0
    )
  )
) 2>NUL

Older Post Stuff

Through chance I had hit upon some ways to exit loops prematurely that did not close the CMD prompt when trying to do other things which gave me this Idea.

NOTE:

While ECHO.>&3 >NUL had worked for me in some scenarios, I have played with this off and on over the years and found that DIR >&0 >NUL was much more consistent.

I am re-writing this answer from here forward to use that method instead as I recently found the old note to myself to use this method instead.

Edited Post with better Method Follows:

DIR >&0 >NUL

The >NUL is optional, I just prefer not to have it output the error.

I prefer to match inLine when possible, as you can see in this sanitized example of a Command I use to monitor LUN Migrations on our VNX.

for /l %L IN (0,0,1) DO @(
   ECHO.& ECHO.===========================================& (
     [VNX CMD] | FINDSTR /R /C:"Source LU Name" /C:"State:" /C:"Time " || DIR >&0 >NUL
   ) & Ping -n 10 1.1.1.1 -w 1000>NUL )

Also, I have another method I found in that note to myself which I just re-tested to confirm works just as well at the CLI as the other method.

Apparently, when I first posted here I posted an older iteration I was playing with instead of the two newer ones which work better:

In this method, we use EXIT /B to exit the For Loop, but we don't want to exit the CLI so we wrap it in a CMD session:

FOR /F %A IN ('CMD /C "FOR /L %L IN (0,1,10000000) DO @( ECHO.%L & IF /I %L EQU 10 ( exit /b  ) )" ') DO @(ECHO %~A)

Because the loop itself happens in the CMD session, we can use EXIT /B to exit the iteration of the loop without losing our CMD Session, and without waiting for the loop to complete, much the same as with the other method.

I would go so far as to say that this method is likely the "intended" method for the sort of scenario where you want to break a for loop at the CLI, as using CMD session is also the only way to get Delayed expansion working at the CLI for your loops, and the behavior and such behavior is clearly an intended workflow to leave a CMD session.

IE: Microsoft clearly made an intentional effort to have CMD Exit /B For loops behave this way, while the "Intended" way of doing this, as my other method, relies on having accidentally created just the right error to kick you out of the loop without letting the loop finish processing, which I only happenstantially discovered, and seems to only reliably work when using the DIR command which is fairly strange.

So that said, I think it's probably a better practice to use Method 2:

FOR /F %A IN ('CMD /C "FOR /L %L IN (0,1,10000000) DO @( ECHO.%L & IF /I %L EQU 10 ( exit /b  ) )" ') DO @(ECHO %~A)

Although I suspect Method 1 is going to be slightly faster:

FOR /L %L IN (0,1,10000000) DO @( ECHO.%L & IF /I %L EQU 10 ( DIR >&) >NUL ) )

And in either case, both should allow DO-While loops as you need for your purposes.

Problem was apparently not the SQL server, but the NAV system that updates the field. There is a compression property that can be used on BLOB fields in NAV, that is not a part of SQL Server. So the custom compression made the data unreadable, though the conversion worked.

The solution was to turn off compression through the Object Designer, Table Designer, Properties for the field (Shift+F4 on the field row).

After that the extraction of data can be made with e.g.: select convert(varchar(max), cast(BLOBFIELD as binary)) from Table

Thanks for all answers that were correct in many ways!

Updated answer, from Peter in comments :

This is de "old terminology", use directally the WSDL2 "endepoint" definition (WSDL2 translated "port" to "endpoint").

Maybe you find an answer in this document : http://www.w3.org/TR/wsdl.html

A WSDL document defines services as collections of network endpoints, or ports. In WSDL, the abstract definition of endpoints and messages is separated from their concrete network deployment or data format bindings. This allows the reuse of abstract definitions: messages, which are abstract descriptions of the data being exchanged, and port types which are abstract collections of operations. The concrete protocol and data format specifications for a particular port type constitutes a reusable binding. A port is defined by associating a network address with a reusable binding, and a collection of ports define a service. Hence, a WSDL document uses the following elements in the definition of network services:

• Types– a container for data type definitions using some type system (such as XSD).
• Message– an abstract, typed definition of the data being communicated.
• Operation– an abstract description of an action supported by the service.
• Port Type–an abstract set of operations supported by one or more endpoints.
• Binding– a concrete protocol and data format specification for a particular port type.
• Port– a single endpoint defined as a combination of a binding and a network address.
• Service– a collection of related endpoints.

http://www.ehow.com/info_12212371_definition-service-endpoint.html

The endpoint is a connection point where HTML files or active server pages are exposed. Endpoints provide information needed to address a Web service endpoint. The endpoint provides a reference or specification that is used to define a group or family of message addressing properties and give end-to-end message characteristics, such as references for the source and destination of endpoints, and the identity of messages to allow for uniform addressing of "independent" messages. The endpoint can be a PC, PDA, or point-of-sale terminal.

dict.items() return list of tuples, and dict.iteritems() return iterator object of tuple in dictionary as (key,value). The tuples are the same, but container is different.

dict.items() basically copies all dictionary into list. Try using following code to compare the execution times of the dict.items() and dict.iteritems(). You will see the difference.

import timeit

d = {i:i*2 for i in xrange(10000000)}  
start = timeit.default_timer() #more memory intensive
for key,value in d.items():
    tmp = key + value #do something like print
t1 = timeit.default_timer() - start

start = timeit.default_timer()
for key,value in d.iteritems(): #less memory intensive
    tmp = key + value
t2 = timeit.default_timer() - start

Output in my machine:

Time with d.items(): 9.04773592949
Time with d.iteritems(): 2.17707300186

This clearly shows that dictionary.iteritems() is much more efficient.

I noticed these problems showing up after upgrading from Angular 5 to Angular 6. I was able to fix this by doing the following in VS2017:

• Ensure the TypeScript SDK was installed (via the Visual Studio Installer) for my particular version of TypeScript, 2.9
• Ensure that the Module System project property is set to match that in my tsconfig.json: ES2015. This is often automatically in sync if the tsconfig file is in the root of the project. However, since I was using the VS Angular template, it places these files in a "ClientApp" subfolder, and the Module System project property was not set.

tsconfig.json:

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "lib": [
      "es2017",
      "dom"
    ],
    "module": "es2015",
    "baseUrl": "./"
  }
}

@DCookie

I just want to point out that you can leave off the lines that say

EXCEPTION  
  WHEN OTHERS THEN    
    RAISE;

You'll get the same effect if you leave off the exception block all together, and the line number reported for the exception will be the line where the exception is actually thrown, not the line in the exception block where it was re-raised.

In Web, simply add the url you want to open:

{  
  "condition": "'test-topic' in topics || 'test-topic-2' in topics",  
  "notification": {
            "title": "FCM Message with condition and link",
            "body": "This is a Firebase Cloud Messaging Topic Message!",            
            "click_action": "https://yoururl.here"
        }
}

for UNIX time-stamp in milliseconds

moment().format('x') // lowerCase x

for UNIX time-stamp in seconds moment().format('X') // capital X

You can use this snippet :-D

using System;
using System.Reflection;

public static class EnumUtils
{
    public static T GetDefaultValue<T>()
        where T : struct, Enum
    {
        return (T)GetDefaultValue(typeof(T));
    }

    public static object GetDefaultValue(Type enumType)
    {
        var attribute = enumType.GetCustomAttribute<DefaultValueAttribute>(inherit: false);
        if (attribute != null)
            return attribute.Value;

        var innerType = enumType.GetEnumUnderlyingType();
        var zero = Activator.CreateInstance(innerType);
        if (enumType.IsEnumDefined(zero))
            return zero;

        var values = enumType.GetEnumValues();
        return values.GetValue(0);
    }
}

Example:

using System;

public enum Enum1
{
    Foo,
    Bar,
    Baz,
    Quux
}
public enum Enum2
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 0
}
public enum Enum3
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}
[DefaultValue(Enum4.Bar)]
public enum Enum4
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}

public static class Program 
{
    public static void Main() 
    {
        var defaultValue1 = EnumUtils.GetDefaultValue<Enum1>();
        Console.WriteLine(defaultValue1); // Foo

        var defaultValue2 = EnumUtils.GetDefaultValue<Enum2>();
        Console.WriteLine(defaultValue2); // Quux

        var defaultValue3 = EnumUtils.GetDefaultValue<Enum3>();
        Console.WriteLine(defaultValue3); // Foo

        var defaultValue4 = EnumUtils.GetDefaultValue<Enum4>();
        Console.WriteLine(defaultValue4); // Bar
    }
}

You can generate a data URI. However, there are browser-specific limitations.

Although this has been answer https://stackoverflow.com/a/28375912/5413283, and regarding padding it is not mentioned in the original answer but here https://stackoverflow.com/a/33697157/5413283.
i am just adding here for visual presentation and a cleaner code.

Tested on Bootstrap 4 ?

Create a new parent div and add the bootstrap collapse. Remove the classes from the textarea

<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
    <textarea class="form-control" rows="4"></textarea>
</div> <!-- // bootstrap class on parent -->

If you want to have spaces around, wrap textarea with padding. Do not add margin, it has the same issue.

<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
    <div class="py-4"> <!-- padding for textarea -->
        <textarea class="form-control" rows="4"></textarea>
    </div> <!-- // padding for textarea -->
</div> <!-- // bootstrap class on parent -->

Tested on Bootstrap 3 ?

Same as bootstrap 4. Wrap the textare with collapse class.

<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
    <textarea class="form-control" rows="4"></textarea>
</div> <!-- // bootstrap class on parent -->

And for padding Bootstrap 3 does not have p-* classes like Bootstrap 4 . So you need to create your own. Do not use padding it will not work, use margin.

#collapseOne textarea {
    margin: 10px 0 10px 0;
}

The JMeter docs say the following:

The summary report creates a table row for each differently named request in your test. This is similar to the Aggregate Report , except that it uses less memory. The thoughput is calculated from the point of view of the sampler target (e.g. the remote server in the case of HTTP samples). JMeter takes into account the total time over which the requests have been generated. If other samplers and timers are in the same thread, these will increase the total time, and therefore reduce the throughput value. So two identical samplers with different names will have half the throughput of two samplers with the same name. It is important to choose the sampler labels correctly to get the best results from the Report.

• Label - The label of the sample. If "Include group name in label?" is selected, then the name of the thread group is added as a prefix. This allows identical labels from different thread groups to be collated separately if required.
• # Samples - The number of samples with the same label
• Average - The average elapsed time of a set of results
• Min - The lowest elapsed time for the samples with the same label
• Max - The longest elapsed time for the samples with the same label
• Std. Dev. - the Standard Deviation of the sample elapsed time
• Error % - Percent of requests with errors
• Throughput - the Throughput is measured in requests per second/minute/hour. The time unit is chosen so that the displayed rate is at least 1.0. When the throughput is saved to a CSV file, it is expressed in requests/second, i.e. 30.0 requests/minute is saved as 0.5.
• Kb/sec - The throughput measured in Kilobytes per second
• Avg. Bytes - average size of the sample response in bytes. (in JMeter 2.2 it wrongly showed the value in kB)

Times are in milliseconds.

I was having an issue with this, my server was running behind a load balancer. The load balancer was terminating the SSL/TLS connection. It then passed the request to the web servers using http.

Using the Url.Action() method with Request.Url.Schema, it kept creating a http url, in my case to create a link in an automated email (which my PenTester didn't like).

I may have cheated a little, but it is exactly what I needed to force a https url:

<a href="@Url.Action("Action", "Controller", new { id = Model.Id }, "https")">Click Here</a>

I actually use a web.config AppSetting so I can use http when debugging locally, but all test and prod environments use transformation to set the https value.

I faced the same problem while executing a curl. I got it right when I changed the following in the php.ini file:

max_execution_time = 1000 ;

and also

max_input_time = 1000 ;

Probably your problem should be solved by making above two changes and restarting the apache server.

Even after changing the above the problem persists and if you think it's because of some database operation using mysql you can try changing this also:

mysql.connect_timeout = 1000 ; // this is not neccessary

All this should be changed in php.ini file and apache server should be restarted to see the changes.

refs is not a DOM element. In order to find a DOM element, you need to use findDOMNode menthod first.

Do, this

var node = ReactDOM.findDOMNode(this.refs.btn);
node.classList.toggle('btn-menu-open');

alternatively, you can use like this (almost actual code)

this.state.styleCondition = false;


<a ref="btn" href="#" className={styleCondition ? "btn-menu show-on-small" : ""}><i></i></a>

you can then change styleCondition based on your state change conditions.

Use this code:

        SqlConnection conn = new SqlConnection();
        conn.ConnectionString = @"Data Source=HOSTNAME\SQLEXPRESS; Initial Catalog=DataBase; Integrated Security=True";
        conn.Open();
        MessageBox.Show("Connection Open  !");
        conn.Close();

Node should support using the http_proxy environmental variable - so it is cross platform and works on system settings rather than requiring a per-application configuration.

Using the provided solutions, I would recommend the following:

Coffeescript

get_url = (url, response) ->
  if process.env.http_proxy?
    match = process.env.http_proxy.match /^(http:\/\/)?([^:\/]+)(:([0-9]+))?/i
    if match
      http.get { host: match[2], port: (if match[4]? then match[4] else 80), path: url }, response
      return
  http.get url, response

Javascript

get_url = function(url, response) {
  var match;
  if (process.env.http_proxy != null) {
    match = process.env.http_proxy.match(/^(http:\/\/)?([^:\/]+)(:([0-9]+))?/i);
    if (match) {
      http.get({
        host: match[2],
        port: (match[4] != null ? match[4] : 80),
        path: url
      }, response);
      return;
    }
  }
  return http.get(url, response);
};

Usage To use the method, effectively just replace http.get, for instance the following writes the index page of google to a file called test.htm:

file = fs.createWriteStream path.resolve(__dirname, "test.htm")
get_url "http://www.google.com.au/", (response) ->
  response.pipe file
  response.on "end", ->
    console.log "complete"

The feedback you get on the interactive interpreter uses repr too. When you type in an expression (let it be expr), the interpreter basically does result = expr; if result is not None: print repr(result). So the second line in your example is formatting the string foo into the representation you want ('foo'). And then the interpreter creates the representation of that, leaving you with double quotes.

Why when I combine %r with double-quote and single quote escapes and print them out, it prints it the way I'd write it in my .py file but not the way I'd like to see it?

I'm not sure what you're asking here. The text single ' and double " quotes, when run through repr, includes escapes for one kind of quote. Of course it does, otherwise it wouldn't be a valid string literal by Python rules. That's precisely what you asked for by calling repr.

Also note that the eval(repr(x)) == x analogy isn't meant literal. It's an approximation and holds true for most (all?) built-in types, but the main thing is that you get a fairly good idea of the type and logical "value" from looking the the repr output.

I've used the TripAdvisor API before and its suited me well. It returns, per destination, a list of top-rated hotels, along with options to retrieve reviews, photos, nearby restaurants and a couple other useful things.

http://www.tripadvisor.com/help/what_type_of_tripadvisor_content_is_available

From the API page (available API content) :

* Hotel, attraction and restaurant ratings and reviews
* Top 10 lists of hotels, attractions and restaurants in a destination
* Traveler photos of a destination
* Travelers' Choice award badges for hotels and destinations

To expand upon @nstehr's answer, you could also use Yahoo Pipes to facilitate a more granular local search. Go to pipes.yahoo.com and do a search for existing hotel pipes and you'll get the idea..

Taken from the MySQL 8.0 Reference Manual:

• utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character.

• utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character.

In MySQL utf8 is currently an alias for utf8mb3 which is deprecated and will be removed in a future MySQL release. At that point utf8 will become a reference to utf8mb4.

So regardless of this alias, you can consciously set yourself an utf8mb4 encoding.

To complete the answer, I'd like to add the @WilliamEntriken's comment below (also taken from the manual):

To avoid ambiguity about the meaning of utf8, consider specifying utf8mb4 explicitly for character set references instead of utf8.

Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.

I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.

Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.

use np.split(..., axis=1):

np.split() is pretty flexible - let's split an original DF into 3 DFs at columns with indexes [2,3]:

doAnswer and thenReturn do the same thing if:

1. You are using Mock, not Spy
2. The method you're stubbing is returning a value, not a void method.

Let's mock this BookService

public interface BookService {
    String getAuthor();
    void queryBookTitle(BookServiceCallback callback);
}

You can stub getAuthor() using doAnswer and thenReturn.

BookService service = mock(BookService.class);
when(service.getAuthor()).thenReturn("Joshua");
// or..
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        return "Joshua";
    }
}).when(service).getAuthor();

Note that when using doAnswer, you can't pass a method on when.

// Will throw UnfinishedStubbingException
doAnswer(invocation -> "Joshua").when(service.getAuthor());

So, when would you use doAnswer instead of thenReturn? I can think of two use cases:

1. When you want to "stub" void method.

Using doAnswer you can do some additionals actions upon method invocation. For example, trigger a callback on queryBookTitle.

BookServiceCallback callback = new BookServiceCallback() {
    @Override
    public void onSuccess(String bookTitle) {
        assertEquals("Effective Java", bookTitle);
    }
};
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        BookServiceCallback callback = (BookServiceCallback) invocation.getArguments()[0];
        callback.onSuccess("Effective Java");
        // return null because queryBookTitle is void
        return null;
    }
}).when(service).queryBookTitle(callback);
service.queryBookTitle(callback);

2. When you are using Spy instead of Mock

When using when-thenReturn on Spy Mockito will call real method and then stub your answer. This can cause a problem if you don't want to call real method, like in this sample:

List list = new LinkedList();
List spy = spy(list);
// Will throw java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
when(spy.get(0)).thenReturn("java");
assertEquals("java", spy.get(0));

Using doAnswer we can stub it safely.

List list = new LinkedList();
List spy = spy(list);
doAnswer(invocation -> "java").when(spy).get(0);
assertEquals("java", spy.get(0));

Actually, if you don't want to do additional actions upon method invocation, you can just use doReturn.

List list = new LinkedList();
List spy = spy(list);
doReturn("java").when(spy).get(0);
assertEquals("java", spy.get(0));

destroy or something similar may come to the CLI, but it is not a primary focus at this time. So you will need to do this manually.

Delete the component directory (assuming you didn't use --flat) and then remove it from the NgModule in which it is declared.

If you are unsure of what to do, I suggest you have a "clean" app meaning no current git changes. Then generate a component and see what is changed in the repo so you can backtrack from there what you will need to do to delete a component.

Update

If you're just experimenting about what you want to generate, you can use the --dry-run flag to not produce any files on disk, just see the updated file list.

i am using the following code please try it out

DateFormat fm= new SimpleDateFormatter();

specify the format of the date you want for example "DD-MM_YYYY" or 'YYYY-mm-dd' then use the java Date datatype as

fm.format("object of java.util.date");

then it will parse your date

You should use white-space with display table

Example:
    legend {
        display:table; /* Enable line-wrapping in IE8+ */
        white-space:normal; /* Enable line-wrapping in old versions of some other browsers */
    }

Simpler one:

var someArray = [...];

function generateSortFn(props) {
    return function (a, b) {
        for (var i = 0; i < props.length; i++) {
            var prop = props[i];
            var name = prop.name;
            var reverse = prop.reverse;
            if (a[name] < b[name])
                return reverse ? 1 : -1;
            if (a[name] > b[name])
                return reverse ? -1 : 1;
        }
        return 0;
    };
};

someArray.sort(generateSortFn([{name: 'prop1', reverse: true}, {name: 'prop2'}]));

I suspect I'm not going to get a look-in on this question, but I am a very experienced programmer, and I hope some of the more open-minded readers will pay attention.

I believe that it suits object-oriented programming languages better for their value-returning procedures (VRPs) to be deterministic and pure.

'VRP' is the modern academic name for a function that is called as part of an expression, and has a return value that notionally replaces the call during evaluation of the expression. E.g. in a statement such as x = 1 + f(y) the function f is serving as a VRP.

'Deterministic' means that the result of the function depends only on the values of its parameters. If you call it again with the same parameter values, you are certain to get the same result.

'Pure' means no side-effects: calling the function does nothing except computing the result. This can be interpreted to mean no important side-effects, in practice, so if the VRP outputs a debugging message every time it is called, for example, that can probably be ignored.

Thus, if, in C#, your function is not deterministic and pure, I say you should make it a void function (in other words, not a VRP), and any value it needs to return should be returned in either an out or a ref parameter.

For example, if you have a function to delete some rows from a database table, and you want it to return the number of rows it deleted, you should declare it something like this:

public void DeleteBasketItems(BasketItemCategory category, out int count);

If you sometimes want to call this function but not get the count, you could always declare an overloading.

You might want to know why this style suits object-oriented programming better. Broadly, it fits into a style of programming that could be (a little imprecisely) termed 'procedural programming', and it is a procedural programming style that fits object-oriented programming better.

Why? The classical model of objects is that they have properties (aka attributes), and you interrogate and manipulate the object (mainly) through reading and updating those properties. A procedural programming style tends to make it easier to do this, because you can execute arbitrary code in between operations that get and set properties.

The downside of procedural programming is that, because you can execute arbitrary code all over the place, you can get some very obtuse and bug-vulnerable interactions via global variables and side-effects.

So, quite simply, it is good practice to signal to someone reading your code that a function could have side-effects by making it non-value returning.

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

if you use jquery you can do like this. from this site Placeholder with Jquery

$('[placeholder]').parents('form').submit(function() {
  $(this).find('[placeholder]').each(function() {
    var input = $(this);
    if (input.val() == input.attr('placeholder')) {
      input.val('');
    }
  })
});

these are the alternate links

1. Placeholder jquery library
2. HTML5 polyfills -- go for placeholder section

A nice one-liner:

dist = numpy.linalg.norm(a-b)

However, if speed is a concern I would recommend experimenting on your machine. I've found that using math library's sqrt with the ** operator for the square is much faster on my machine than the one-liner NumPy solution.

I ran my tests using this simple program:

#!/usr/bin/python
import math
import numpy
from random import uniform

def fastest_calc_dist(p1,p2):
    return math.sqrt((p2[0] - p1[0]) ** 2 +
                     (p2[1] - p1[1]) ** 2 +
                     (p2[2] - p1[2]) ** 2)

def math_calc_dist(p1,p2):
    return math.sqrt(math.pow((p2[0] - p1[0]), 2) +
                     math.pow((p2[1] - p1[1]), 2) +
                     math.pow((p2[2] - p1[2]), 2))

def numpy_calc_dist(p1,p2):
    return numpy.linalg.norm(numpy.array(p1)-numpy.array(p2))

TOTAL_LOCATIONS = 1000

p1 = dict()
p2 = dict()
for i in range(0, TOTAL_LOCATIONS):
    p1[i] = (uniform(0,1000),uniform(0,1000),uniform(0,1000))
    p2[i] = (uniform(0,1000),uniform(0,1000),uniform(0,1000))

total_dist = 0
for i in range(0, TOTAL_LOCATIONS):
    for j in range(0, TOTAL_LOCATIONS):
        dist = fastest_calc_dist(p1[i], p2[j]) #change this line for testing
        total_dist += dist

print total_dist

On my machine, math_calc_dist runs much faster than numpy_calc_dist: 1.5 seconds versus 23.5 seconds.

To get a measurable difference between fastest_calc_dist and math_calc_dist I had to up TOTAL_LOCATIONS to 6000. Then fastest_calc_dist takes ~50 seconds while math_calc_dist takes ~60 seconds.

You can also experiment with numpy.sqrt and numpy.square though both were slower than the math alternatives on my machine.

My tests were run with Python 2.6.6.

git stash && git stash pop

type FunctionName = (n: inputType) => any;

class ClassName {
    save(callback: FunctionName) : void {
        callback(data);
    }
}

This surely aligns with the functional programming paradigm.

We tend to get this message when we try to subscribe to a topic that has not been created yet. We generally rely on topics to be created a priori in our deployed environments, but we have component tests that run against a dockerized kafka instance, which starts clean every time.

In that case, we use AdminUtils in our test setup to check if the topic exists and create it if not. See this other stack overflow for more about setting up AdminUtils.

When the number is not big, everything seems just right. But if it isn't, great caution is required to achieve correctness.

Take double as an example:

If it is not big, as others mentioned you can just try this simply:

doubles.stream().mapToDouble(d -> d).average().orElse(0.0);

However, if it's out of your control and quite big, you have to turn to BigDecimal as follows (methods in the old answers using BigDecimal actually are wrong).

doubles.stream().map(BigDecimal::valueOf).reduce(BigDecimal.ZERO, BigDecimal::add)
       .divide(BigDecimal.valueOf(doubles.size())).doubleValue();

Enclose the tests I carried out to demonstrate my point:

    @Test
    public void testAvgDouble() {
        assertEquals(5.0, getAvgBasic(Stream.of(2.0, 4.0, 6.0, 8.0)), 1E-5);
        List<Double> doubleList = new ArrayList<>(Arrays.asList(Math.pow(10, 308), Math.pow(10, 308), Math.pow(10, 308), Math.pow(10, 308)));
        // Double.MAX_VALUE = 1.7976931348623157e+308
        BigDecimal doubleSum = BigDecimal.ZERO;
        for (Double d : doubleList) {
            doubleSum =  doubleSum.add(new BigDecimal(d.toString()));
        }
        out.println(doubleSum.divide(valueOf(doubleList.size())).doubleValue());
        out.println(getAvgUsingRealBigDecimal(doubleList.stream()));
        out.println(getAvgBasic(doubleList.stream()));
        out.println(getAvgUsingFakeBigDecimal(doubleList.stream()));
    }

    private double getAvgBasic(Stream<Double> doubleStream) {
        return doubleStream.mapToDouble(d -> d).average().orElse(0.0);
    }

    private double getAvgUsingFakeBigDecimal(Stream<Double> doubleStream) {
        return doubleStream.map(BigDecimal::valueOf)
                .collect(Collectors.averagingDouble(BigDecimal::doubleValue));
    }

    private double getAvgUsingRealBigDecimal(Stream<Double> doubleStream) {
        List<Double> doubles = doubleStream.collect(Collectors.toList());
        return doubles.stream().map(BigDecimal::valueOf).reduce(BigDecimal.ZERO, BigDecimal::add)
                .divide(valueOf(doubles.size()), BigDecimal.ROUND_DOWN).doubleValue();
    }

As for Integer or Long, correspondingly you can use BigInteger similarly.

Here you are ;-)

This is an old question, but the current answers are incorrect :)

Use yum whatprovides, with the absolute path to the file you want (which may be wildcarded). For example:

yum whatprovides '*bin/grep'

Returns

grep-2.5.1-55.el5.x86_64 : The GNU versions of grep pattern matching utilities.
Repo        : base
Matched from:
Filename    : /bin/grep

You may prefer the output and speed of the repoquery tool, available in the yum-utils package.

sudo yum install yum-utils
repoquery --whatprovides '*bin/grep'
grep-0:2.5.1-55.el5.x86_64
grep-0:2.5.1-55.el5.x86_64

repoquery can do other queries such as listing package contents, dependencies, reverse-dependencies, etc.

using select-object for example:

Get-ADUser -Filter * -SearchBase 'OU=Users & Computers, DC=aaaaaaa, DC=com' -Properties DisplayName | select -expand displayname | Export-CSV "ADUsers.csv" 

Similar to @Rhusfer answer I wrote this. In case you have a group of EditTexts and want to concatenate their values, you can write:

listOf(edit_1, edit_2, edit_3, edit_4).joinToString(separator = "") { it.text.toString() }

If you want to concatenate Map, use this:

map.entries.joinToString(separator = ", ")

To concatenate Bundle, use

bundle.keySet().joinToString(", ") { key -> "$key=${bundle[key]}" }

It sorts keys in alphabetical order.

Example:

val map: MutableMap<String, Any> = mutableMapOf("price" to 20.5)
map += "arrange" to 0
map += "title" to "Night cream"
println(map.entries.joinToString(separator = ", "))

// price=20.5, arrange=0, title=Night cream

val bundle = bundleOf("price" to 20.5)
bundle.putAll(bundleOf("arrange" to 0))
bundle.putAll(bundleOf("title" to "Night cream"))
val bundleString =
    bundle.keySet().joinToString(", ") { key -> "$key=${bundle[key]}" }
println(bundleString)

// arrange=0, price=20.5, title=Night cream

Set data to this:

data ={"eventType":"AAS_PORTAL_START","data":{"uid":"hfe3hf45huf33545","aid":"1","vid":"1"}}

There are more than a few ways. I'll list them in order of inverted preference (i.e., best first, worst last):

1. Treat it like a module: import file. This is good because it's secure, fast, and maintainable. Code gets reused as it's supposed to be done. Most Python libraries run using multiple methods stretched over lots of files. Highly recommended. Note that if your file is called file.py, your import should not include the .py extension at the end.
2. The infamous (and unsafe) exec command: Insecure, hacky, usually the wrong answer. Avoid where possible.
   • execfile('file.py') in Python 2
   • exec(open('file.py').read()) in Python 3
3. Spawn a shell process: os.system('python file.py'). Use when desperate.

Or take the .not() method

https://api.jquery.com/not/

$(".thisClass").not("#thisId").doAction();

You just can use doStuff($event) in your markup and get the data-attribute values via currentTarget.getAttribute("data-id")) in angular. HTML:

<div ng-controller="TestCtrl">
    <button data-id="345" ng-click="doStuff($event)">Button</button>
</div>

JS:

var app = angular.module("app", []);
app.controller("TestCtrl", function ($scope) {
    $scope.doStuff = function (item) {
        console.log(item.currentTarget);
        console.log(item.currentTarget.getAttribute("data-id"));
    };
});

An easier option may be to log the POST data before it gets to the server. For web applications, I use Burp Proxy and set Firefox to use it as an HTTP/S proxy, and then I can watch (and mangle) data 'on the wire' in real time.

For making API requests without a browser, SoapUI is very useful and may show similar info. I would bet that you could probably configure SoapUI to connect through Burp as well (just a guess though).

As per my observation like two cases, if a table has less then 100,000 records then the join will work fast.

But in the case that a table has more than 100,000 records then a subquery is best result.

I have one table that has 500,000 records on that I created below query and its result time is like

SELECT * 
FROM crv.workorder_details wd 
inner join  crv.workorder wr on wr.workorder_id = wd.workorder_id;

Result : 13.3 Seconds

select * 
from crv.workorder_details 
where workorder_id in (select workorder_id from crv.workorder)

Result : 1.65 Seconds

I had to use this kind of code for a scanner that pasted stuff into the field

$(document).ready(function() {
  var tId,oldVal;
  $("#fieldId").focus(function() {
     oldVal = $("#fieldId").val();
     tId=setInterval(function() { 
      var newVal = $("#fieldId").val(); 
      if (oldVal!=newVal) oldVal=newVal;
      someaction() },100);
  });
  $("#fieldId").blur(function(){ clearInterval(tId)});
});

Not tested...

I had the same problem too, but I found a solution.

root.mainloop()

from tkinter import *
    
# must add
root = Tk()
root.title("Calculator")
root.iconbitmap(r"image/icon.ico")
    
root.mainloop()

In the example, what python needed is an icon file, so when you dowload an icon as .png it won't work cause it needs an .ico file. So you need to find converters to convert your icon from png to ico.

I know there should be a proper way to solve it but just to save time

I uploaded my xlsx sheet to Google Sheets and then again downloaded it from Google Sheets it working now

If you don't have time to solve the problem, you can try this

A scriptable object is an object that records the operations done to it and it can store them as a "script" which can be replayed.

For example, see: Application Scripting Framework

Now, if Alistair didn't know what he asked and really meant "subscriptable" objects (as edited by others), then (as mipadi also answered) this is the correct one:

A subscriptable object is any object that implements the __getitem__ special method (think lists, dictionaries).

I wrote a small helper method to read Paths from your class resources. It is quite handy to use as it only needs a reference of the class you have stored your resources as well as the name of the resource itself.

public static Path getResourcePath(Class<?> resourceClass, String resourceName) throws URISyntaxException {
    URL url = resourceClass.getResource(resourceName);
    return Paths.get(url.toURI());
}  

You can convert it to char* if you don't need a modifiable string by using:

(char*) yourString.c_str();

This would be very useful when you want to publish a String variable via MQTT in arduino.

public static class Utilities
{
    public static T Deserialize<T>(string jsonString)
    {
        using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(jsonString)))
        {    
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
            return (T)serializer.ReadObject(ms);
        }
    }
}

This is the easiest way to do it: http://jsfiddle.net/thirtydot/jwJBd/

(or with table-layout: fixed for even width distribution: http://jsfiddle.net/thirtydot/jwJBd/59/)

This won't work in IE7.

#horizontal-style {
    display: table;
    width: 100%;
    /*table-layout: fixed;*/
}
#horizontal-style li {
    display: table-cell;
}
#horizontal-style a {

_{Old answer before your edit: http://jsfiddle.net/thirtydot/DsqWr/}

This solution builds upon previous solutions, but takes into account both metric and binary units:

function formatBytes(bytes, decimals, binaryUnits) {
    if(bytes == 0) {
        return '0 Bytes';
    }
    var unitMultiple = (binaryUnits) ? 1024 : 1000; 
    var unitNames = (unitMultiple === 1024) ? // 1000 bytes in 1 Kilobyte (KB) or 1024 bytes for the binary version (KiB)
        ['Bytes', 'KiB', 'MiB', 'GiB', 'TiB', 'PiB', 'EiB', 'ZiB', 'YiB']: 
        ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];
    var unitChanges = Math.floor(Math.log(bytes) / Math.log(unitMultiple));
    return parseFloat((bytes / Math.pow(unitMultiple, unitChanges)).toFixed(decimals || 0)) + ' ' + unitNames[unitChanges];
}

Examples:

formatBytes(293489203947847, 1);    // 293.5 TB
formatBytes(1234, 0);   // 1 KB
formatBytes(4534634523453678343456, 2); // 4.53 ZB
formatBytes(4534634523453678343456, 2, true));  // 3.84 ZiB
formatBytes(4566744, 1);    // 4.6 MB
formatBytes(534, 0);    // 534 Bytes
formatBytes(273403407, 0);  // 273 MB

I resolved by removing @Basic(optional = false) property or just update boolean @Basic(optional = true)

One better way would be to use SELECT COUNT statement of SQL.

Just when you need the count of number of rows returned, execute another query returning the exact number of result of that query.

 try
{
   Conn=ConnectionODBC.getConnection();
   Statement stmt = Conn.createStatement();        
    String sqlStmt = sql;        
    String sqlrow = SELECT COUNT(*) from (sql) rowquery;
    String total = stmt.executeQuery(sqlrow);
    int rowcount = total.getInt(1);
    }

I've found in www.laughing-buddha.net/php/lib/dirlist/ a function that returns an array containing a list of a directory's contents.

Also look at php.net http://es.php.net/manual/es/ref.filesystem.php where you'll find additional functions for working with files in php.

I usually include a small function in my objects which allows me to dump to array or json or xml. Something like:

public function exportObj($method = 'a')
{
     if($method == 'j')
     {
         return json_encode(get_object_vars($this));
     }
     else
     {
         return get_object_vars($this);
     }
}

either way, get_object_vars() is probably useful to you.

You can also add items in code:

cboWhatever.Items.Add("SomeItem");

Also, to add something where you control display/value, (almost categorically needed in my experience) you can do so. I found a good stackoverflow reference here:

Key Value Pair Combobox in WPF

Sum-up code would be something like this:

ComboBox cboSomething = new ComboBox();
cboSomething.DisplayMemberPath = "Key";
cboSomething.SelectedValuePath = "Value";
cboSomething.Items.Add(new KeyValuePair<string, string>("Something", "WhyNot"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Deus", "Why"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Flirptidee", "Stuff"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Fernum", "Blictor"));

METHOD 1: I deleted the androidTestCompile on espresso-core line which was automatically included in a new project. Then my Android Studio compiles clean.

The androidTestCompile is in "build.gradle (Module:app)":

dependencies {
    ...
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    ...
}

I don't know whether this deletion will have any problem down the road, but it surely works for my current project now.

METHOD 2: Adding an exclude on findbugs works too:

dependencies {
    ...
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
        exclude group: 'com.google.code.findbugs'
    })
    ...
}

METHOD 3: Forcing compiling with a specific version:

(In the following I force it to compile with the higher version.)

dependencies {
    ...
    androidTestCompile 'com.google.code.findbugs:jsr305:3.0.0'
    ...
}

The Instant class doesn't contain Zone information, it only stores timestamp in milliseconds from UNIX epoch, i.e. 1 Jan 1070 from UTC. So, formatter can't print a date because date always printed for concrete time zone. You should set time zone to formatter and all will be fine, like this :

Instant instant = Instant.ofEpochMilli(92554380000L);
DateTimeFormatter formatter = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.SHORT).withLocale(Locale.UK).withZone(ZoneOffset.UTC);
assert formatter.format(instant).equals("07/12/72 05:33");
assert instant.toString().equals("1972-12-07T05:33:00Z");

Check this snip out.

# reading the JSON data using json.load()
file = 'data.json'
with open(file) as train_file:
    dict_train = json.load(train_file)

# converting json dataset from dictionary to dataframe

train.reset_index(level=0, inplace=True)

CORS issue can be simply resolved by following this:

Create a new shortcut of Google Chrome(update browser installation path accordingly) with following value:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="D:\chrome\temp"

In RStudio, there are (at least) 3 ways:

1. Press the F2 key while cursor is on any function.
2. Click on the function name while holding Ctrl or Command
3. View(function_name) (as stated above)

A new pane will open with the source code. If you reach .Primitive or .C you'll need another method, sorry.

The simplest way of doing this which I find useful is the below.

This might not be the official way but it works well.

Suppose you have a project named "XYZ" on your PC. Now you want to make a git repo of this project on github and use its functionalities.

Step 1: go to "www.github.com"

Step 2: create a repository with a "README.md" file (name it as you like it)

Step 3: clone the repository to your PC.

Step 4: In the cloned folder you will get two things : ".git" folder and a "README.md" file. Copy these two in your project folder "XYZ".

Step 5: Delete the cloned repo.

Step 6: add, commit and push all the files and folders of your project.

Now, you can just use your project "XYZ" as a git repository.

Other than foreground/background term. Another way to hide running window is via vbscript, if is is still available in your system.

DIM objShell
set objShell=wscript.createObject("wscript.shell")
iReturn=objShell.Run("yourcommand.exe", 0, TRUE)

name it as sth.vbs and call it from bat, put in sheduled task, etc. PersonallyI'll disable vbs with no haste at any Windows system I manage :)

I resolved it by adding the jar file containing the imported classes into WEB-INF/Lib.

sometimes you need to set Padding, not Margin to make space between items smaller than default

Absolutely, positively option A. Others have mentioned that databases generally don't deal well with BLOBs, whether they're designed to do so or not. Filesystems, on the other hand, live for this stuff. You have the option of using RAID striping, spreading images across multiple drives, even spreading them across geographically disparate servers.

Another advantage is your database backups/replication would be monstrous.

Couldn't you just reverse the string and replace only the first occurrence of the reversed search pattern? I'm thinking . . .

var list = ['one', 'two', 'three', 'four'];
var str = 'one two, one three, one four, one';
for ( var i = 0; i < list.length; i++)
{
     if (str.endsWith(list[i])
     {
         var reversedHaystack = str.split('').reverse().join('');
         var reversedNeedle = list[i].split('').reverse().join('');

         reversedHaystack = reversedHaystack.replace(reversedNeedle, 'hsinif');
         str = reversedHaystack.split('').reverse().join('');
     }
 }

maven should be on the system's PATH if you wish to execute it from any place. add %M2_HOME%\bin to the PATH

If you're googling this, and don't want the event listener to be an attribute, use:

document.getElementById('my-select').addEventListener('change', function() {_x000D_
  console.log('You selected: ', this.value);_x000D_
});

<select id="my-select">_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
</select>

If you are using Android Lollipop i.e. SDK 21, then:

CookieManager.getInstance().setAcceptCookie(true);

won't work. You need to use:

CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);

I ran into same issue and the above line worked as a charm.

try this

INSERT INTO exampleTbl VALUES('he doesn''t work for me')

If you want to avoid fencepost errors and avoid moving and deleting items in an array, here is a somewhat verbose solution that uses List:

import java.util.ArrayList;
import java.util.List;

public class RemoveNullValue {
  public static void main( String args[] ) {
    String[] firstArray = {"test1", "", "test2", "test4", "", null};

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

    for(String s : firstArray) {
       if(s != null && s.length() > 0) {
          list.add(s);
       }
    }

    firstArray = list.toArray(new String[list.size()]);
  }
}

Added null to show the difference between an empty String instance ("") and null.

Since this answer is around 4.5 years old, I'm adding a Java 8 example:

import java.util.Arrays;
import java.util.stream.Collectors;

public class RemoveNullValue {
    public static void main( String args[] ) {
        String[] firstArray = {"test1", "", "test2", "test4", "", null};

        firstArray = Arrays.stream(firstArray)
                     .filter(s -> (s != null && s.length() > 0))
                     .toArray(String[]::new);    

    }
}

A @ViewScoped bean lives exactly as long as a JSF view. It usually starts with a fresh new GET request, or with a navigation action, and will then live as long as the enduser submits any POST form in the view to an action method which returns null or void (and thus navigates back to the same view). Once you refresh the page, or return a non-null string (even an empty string!) navigation outcome, then the view scope will end.

A @RequestScoped bean lives exactly as long a HTTP request. It will thus be garbaged by end of every request and recreated on every new request, hereby losing all changed properties.

A @ViewScoped bean is thus particularly more useful in rich Ajax-enabled views which needs to remember the (changed) view state across Ajax requests. A @RequestScoped one would be recreated on every Ajax request and thus fail to remember all changed view state. Note that a @ViewScoped bean does not share any data among different browser tabs/windows in the same session like as a @SessionScoped bean. Every view has its own unique @ViewScoped bean.

See also:

• How to choose the right bean scope?
• The benefits and pitfalls of @ViewScoped

The easiest way to pass additional data is to add the data to the existing ViewData for the view as @Joel Martinez notes. However, if you don't want to pollute your ViewData, RenderPartial has a method that takes three arguments as well as the two-argument version you show. The third argument is a ViewDataDictionary. You can construct a separate ViewDataDictionary just for your partial containing just the extra data that you want to pass in.

@Patrick I would improve your solution a bit

@Override
public Object deserialize(JsonParser jp, DeserializationContext ctxt)
        throws IOException, JsonProcessingException {        
    ObjectNode objectNode = jp.readValueAsTree();
    JsonNode wrapped = objectNode.get(wrapperKey);
    JsonParser parser = node.traverse();
    parser.setCodec(jp.getCodec());
    Vendor mapped = parser.readValueAs(Vendor.class);
    return mapped;
}

It works faster :)

Try to use getAsJsonObject() instead of a straight cast used in the accepted answer:

JsonObject o = new JsonParser().parse("{\"a\": \"A\"}").getAsJsonObject();

Use

git apply patchfile

if possible.

patch -p1 < patchfile 

has potential side-effect.

git apply also handles file adds, deletes, and renames if they're described in the git diff format, which patch won't do. Finally, git apply is an "apply all or abort all" model where either everything is applied or nothing is, whereas patch can partially apply patch files, leaving your working directory in a weird state.

If you are not sharing develop branch with anybody, then I would just rebase it every time master updated, that way you will not have merge commits all over your history once you will merge develop back into master. Workflow in this case would be as follows:

> git clone git://<remote_repo_path>/ <local_repo>
> cd <local_repo>
> git checkout -b develop
....do a lot of work on develop
....do all the commits
> git pull origin master
> git rebase master develop

Above steps will ensure that your develop branch will be always on top of the latest changes from the master branch. Once you are done with develop branch and it's rebased to the latest changes on master you can just merge it back:

> git checkout -b master
> git merge develop
> git branch -d develop

Use merge():

$request->merge([
    'user_id' => $modified_user_id_here,
]);

Simple! No need to transfer the entire $request->all() to another variable.

Though this question is rather old, here's a answer :)

What you are asking for can be achieved by using jQuery's .click() event method and .on() event method

So this could be the code:

// Set the global variables
var userImage = $("#img-giLkojRpuK");
var hangoutButton = $("#hangout-giLkojRpuK");

$(document).ready(function() {
    // When the document is ready/loaded, execute function

    // Hide hangoutButton
    hangoutButton.hide();

    // Assign "click"-event-method to userImage
    userImage.on("click", function() {
        console.log("in onclick");
        hangoutButton.click();
    });
});

For individual variables you want to make available on a one off basis you can make it part of the command.

sudo http_proxy=$http_proxy wget "http://stackoverflow.com"

I just spent a few hours on this error, and while the other answers here helped me understand what was going on, they did not fix my particular problem.

I am working on a project that compiles using both clang++ and g++. I was having no linking issues using clang++, but was getting the undefined reference to 'typeinfo for error with g++.

The important point: Linking order MATTERS with g++. If you list the libraries you want to link in an order which is incorrect you can get the typeinfo error.

See this SO question for more details on linking order with gcc/g++.

I'm not entirely sure that I've understood the question because this is a fairly straightforward answer, but here goes... :)

Have you tried setting the overflow property of the container to visible or auto?

#some_div {
    height:100%;
    background:black; 
    overflow: visible;
    }

Adding that should push the black container to whatever size your dynamic container requires. I prefer visible to auto because auto seems to come with scroll bars...

if you just scrollheight it will make a problem when user will want to see his previous message. so you need to make something that when new message come only then the code. use jquery latest version. 1.here I checked the height before message loaded. 2. again check the new height. 3. if the height is different only that time it will scroll otherwise it will not scroll. 4. not in the if condition you can put any ringtone or any other feature that you need. that will play when new message will come. thanks

var oldscrollHeight = $("#messages").prop("scrollHeight");
$.get('msg_show.php', function(data) {
    div.html(data);
    var newscrollHeight = $("#messages").prop("scrollHeight"); //Scroll height after the request
    if (newscrollHeight > oldscrollHeight) {
        $("#messages").animate({
            scrollTop: newscrollHeight
        }, 'normal'); //Autoscroll to bottom of div
    }

In my case, I made the change on my hard drive (cut/pasted about 200 folders/files from one path in my working copy to another path in my working copy), and used SourceTree (2.0.20.1) to stage both the detected changes (one add, one remove), and as long as I staged both the add and remove together, it automatically combined into a single change with a pink R icon (rename I assume).

I did notice that because I had such a large number of changes at once, SourceTree was a little slow detecting all the changes, so some of my staged files look like just adds (green plus) or just deletes (red minus), but I kept refreshing the file status and kept staging new changes as they eventually popped up, and after a few minutes, the whole list was perfect and ready for commit.

I verified that the history is present, as long as when I look for history, I check the "Follow renamed files" option.

Uses Guava's static factory methods for Maps and is only 105 characters long.

private static final Map<Class<? extends Persistent>, PersistentHelper> class2helper = Maps.newHashMap();

I took Crystalonics' answer and turned them into extension methods. I hope someone else will find them useful:

public static byte[] SerializeToByteArray(this object obj)
{
    if (obj == null)
    {
        return null;
    }
    var bf = new BinaryFormatter();
    using (var ms = new MemoryStream())
    {
        bf.Serialize(ms, obj);
        return ms.ToArray();
    }
}

public static T Deserialize<T>(this byte[] byteArray) where T : class
{
    if (byteArray == null)
    {
        return null;
    }
    using (var memStream = new MemoryStream())
    {
        var binForm = new BinaryFormatter();
        memStream.Write(byteArray, 0, byteArray.Length);
        memStream.Seek(0, SeekOrigin.Begin);
        var obj = (T)binForm.Deserialize(memStream);
        return obj;
    }
}

use MAX in your SELECT to return on value.. EXAMPLE

INSERT INTO school_year_studentid (student_id,syr_id) VALUES
((SELECT MAX(student_id) FROM student), (SELECT MAX(syr_id) FROM school_year))

instead of

INSERT INTO school_year_studentid (student_id,syr_id) VALUES
((SELECT (student_id) FROM student), (SELECT (syr_id) FROM school_year))

try it without MAX it will more than one value

One option is strtok

example:

char name[20];
//pretend name is set to the value "My name"

You want to split it at the space between the two words

split=strtok(name," ");

while(split != NULL)
{
    word=split;
    split=strtok(NULL," ");
}

I couldn't get any of the commands on this page to work for me: the sed solution added a newline to the end of all the files it processed, and the perl solution was unable to accept enough arguments from find. I found this solution which works perfectly:

find . -type f -name '*.[hm]' -print0 
    | xargs -0 perl -pi -e 's/search_regex/replacement_string/g'

This will recurse down the current directory tree and replace search_regex with replacement_string in any files ending in .h or .m.

I have also used rpl for this purpose in the past.

For me the easiest way was to read the last versions of the project with a combination of curl, grep, sort and tail.

My format: service-(version: 1.9.23)-(buildnumber)156.tar.gz

versionToDownload=$(curl -u$user:$password 'https://$artifactory/artifactory/$project/' | grep -o 'service-[^"]*.tar.gz' | sort | tail -1)

As a complementary, for those who might meet the same issue as mine, I'm using $.ajax to post form data to server and I also got the 400 error at first.

Assume I have a javascript variable,

var formData = {
    "name":"Gearon",
    "hobby":"Be different"
    }; 

Do not use variable formData directly as the value of key data like below:

$.ajax({
    type: "post",
    dataType: "json",
    url: "http://localhost/user/add",
    contentType: "application/json",
    data: formData,
    success: function(data, textStatus){
        alert("Data: " + data + "\nStatus: " + status); 
    }
});

Instead, use JSON.stringify to encapsulate the formData as below:

$.ajax({
    type: "post",
    dataType: "json",
    url: "http://localhost/user/add",
    contentType: "application/json",
    data: JSON.stringify(formData),
    success: function(data, textStatus){
        alert("Data: " + data + "\nStatus: " + status); 
    }
});

Anyway, as others have illustrated, the error is because the server could not recognize the request cause malformed syntax, I'm just raising a instance at practice. Hope it would be helpful to someone.

Not a direct answer to this question but rather to the "issue" of $event.currentTarget apparently be set to null.

This is due to the fact that console.log shows deep mutable objects at the last state of execution, not at the state when console.log was called.

You can check this for more information: Consecutive calls to console.log produce inconsistent results

Just always compare the Date property of DateTime, instead of the full date time.

When you make your LINQ query, use date.Date in the query, ie:

var results = from c in collection
              where c.Date == myDateTime.Date
              select c;

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

The terminology "dynamically typed" is unfortunately misleading. All languages are statically typed, and types are properties of expressions (not of values as some think). However, some languages have only one type. These are called uni-typed languages. One example of such a language is the untyped lambda calculus.

In the untyped lambda calculus, all terms are lambda terms, and the only operation that can be performed on a term is applying it to another term. Hence all operations always result in either infinite recursion or a lambda term, but never signal an error.

However, were we to augment the untyped lambda calculus with primitive numbers and arithmetic operations, then we could perform nonsensical operations, such adding two lambda terms together: (?x.x) + (?y.y). One could argue that the only sane thing to do is to signal an error when this happens, but to be able to do this, each value has to be tagged with an indicator that indicates whether the term is a lambda term or a number. The addition operator will then check that indeed both arguments are tagged as numbers, and if they aren't, signal an error. Note that these tags are not types, because types are properties of programs, not of values produced by those programs.

A uni-typed language that does this is called dynamically typed.

Languages such as JavaScript, Python, and Ruby are all uni-typed. Again, the typeof operator in JavaScript and the type function in Python have misleading names; they return the tags associated with the operands, not their types. Similarly, dynamic_cast in C++ and instanceof in Java do not do type checks.

<?php
if (isset($_POST['str'])){
function printme($str){
echo $str;
}

printme("{$_POST['str']}");
}
?>
<form action="<?php $_PHP_SELF ?>" method="POST">

</form>

return $this->output
            ->set_content_type('application/json')
            ->set_status_header(500)

                    'type' => 'danger'
            )));

I have found the solution to this issue using ObjectDoesNotExist on this way

I am linking to what essentially is the same discussion where Peter Lawrey is providing a good answer. Why I get a negative elapsed time using System.nanoTime()?

Many people mentioned that in Java System.nanoTime() could return negative time. I for apologize for repeating what other people already said.

1. nanoTime() is not a clock but CPU cycle counter.
2. Return value is divided by frequency to look like time.
3. CPU frequency may fluctuate.
4. When your thread is scheduled on another CPU, there is a chance of getting nanoTime() which results in a negative difference. That's logical. Counters across CPUs are not synchronized.
5. In many cases, you could get quite misleading results but you wouldn't be able to tell because delta is not negative. Think about it.
6. (unconfirmed) I think you may get a negative result even on the same CPU if instructions are reordered. To prevent that, you'd have to invoke a memory barrier serializing your instructions.

It'd be cool if System.nanoTime() returned coreID where it executed.

As the az7ar answer is beautifully said but Let me make it simpler with socket.io rooms. request a server with a unique identifier to join a server. here we are using an email as a unique identifier.

Client Socket.io

socket.on('connect', function () {
  socket.emit('join', {email: [email protected]});
});

When the user joined a server, create a room for that user

Server Socket.io

io.on('connection', function (socket) {
   socket.on('join', function (data) {    
    socket.join(data.email);
  });
});

Now we are all set with joining. let emit something to from the server to room, so that user can listen.

Server Socket.io

io.to('[email protected]').emit('message', {msg: 'hello world.'});

Let finalize the topic with listening to message event to the client side

socket.on("message", function(data) {
  alert(data.msg);
});

The reference from Socket.io rooms

It is possible to increase heap size allocated by the JVM in eclipse directly In eclipse IDE goto

Run---->Run Configurations---->Arguments

Enter -Xmx1g(It is used to set the max size like Xmx256m or Xmx1g...... m-->mb g--->gb)

With Javascript you can use:

yourtext.substr(0,1).toUpperCase()+yourtext.substr(1);

If by chance you're generating your web page with PHP you can also use:

<?=ucfirst($your_text)?>

I got stuck in this. I created the head-name file, and then I ran into another error saying it couldn't find the onto file, so I created that file. Then I got another error saying could not read '.git/rebase-apply/onto': No such file or directory.

So I looked at the git documentation for rebasing and found another command:

git rebase --quit

This set me back on my branch with no changes, and I could start my rebase over again, good as new.

If you are doing this because you want more context in your search, you can do this:

cat BIG_FILE.txt | less

Doing a search in less should highlight your search terms.

Or pipe the output to your favorite editor. One example:

cat BIG_FILE.txt | vim -

Then search/highlight/replace.

/^[\+\-]?\d*\.?\d+(?:[Ee][\+\-]?\d+)?$/

Had a similar problem, where I had to set the form back to pristine, but also to untouched, since $invalid and $error were both used to show error messages. Only using setPristine() was not enough to clear the error messages.

I solved it by using setPristine() and setUntouched(). (See Angular's documentation: https://docs.angularjs.org/api/ng/type/ngModel.NgModelController)

So, in my controller, I used:

$scope.form.setPristine(); 
$scope.form.setUntouched();

These two functions reset the complete form to $pristine and back to $untouched, so that all error messages were cleared.

First of all, shouldn't there be a CustomerId in the Invoices table? As it is, You can't perform this query for Invoices that have no payments on them as yet. If there are no payments on an invoice, that invoice will not even show up in the ouput of the query, even though it's an outer join...

Also, When a customer makes a payment, how do you know what Invoice to attach it to ? If the only way is by the InvoiceId on the stub that arrives with the payment, then you are (perhaps inappropriately) associating Invoices with the customer that paid them, rather than with the customer that ordered them... . (Sometimes an invoice can be paid by someone other than the customer who ordered the services)

On my Ubuntu VM, with 1048 MB total RAM, java -XX:+PrintFlagsFinal -version | grep HeapSize printed : uintx MaxHeapSize := 266338304, which is approx 266MB and is 1/4th of my total RAM.

Here's a short, simple generic answer with a nice syntax for a named tuple with default arguments:

import collections

def dnamedtuple(typename, field_names, **defaults):
    fields = sorted(field_names.split(), key=lambda x: x in defaults)
    T = collections.namedtuple(typename, ' '.join(fields))
    T.__new__.__defaults__ = tuple(defaults[field] for field in fields[-len(defaults):])
    return T

Usage:

Test = dnamedtuple('Test', 'one two three', two=2)
Test(1, 3)  # Test(one=1, three=3, two=2)

Minified:

def dnamedtuple(tp, fs, **df):
    fs = sorted(fs.split(), key=df.__contains__)
    T = collections.namedtuple(tp, ' '.join(fs))
    T.__new__.__defaults__ = tuple(df[i] for i in fs[-len(df):])
    return T

Most compact method, assuming all sub-dirs are git repos:

ls | parallel git -C {} pull

while Alexey Kukanov's answer may be more efficient, you can also iterate through a queue in a very natural manner, by popping each element from the front of the queue, then pushing it to the back:

#include <iostream>
#include <queue>

using namespace std;

int main() {
    //populate queue
    queue<int> q;
    for (int i = 0; i < 10; ++i) q.push(i);

    // iterate through queue
    for (size_t i = 0; i < q.size(); ++i) {
        int elem = std::move(q.front());
        q.pop();
        elem *= elem;
        q.push(std::move(elem));
    }

    //print queue
    while (!q.empty()) {
        cout << q.front() << ' ';
        q.pop();
    }
}

output:

0 1 4 9 16 25 36 49 64 81 

There aren't a lot of "Best Practices" yet. Those of us that are using inline-styles, for React components, are still very much experimenting.

There are a number of approaches that vary wildly: React inline-style lib comparison chart

All or nothing?

What we refer to as "style" actually includes quite a few concepts:

• Layout — how an element/component looks in relationship to others
• Appearance — the characteristics of an element/component
• Behavior and state — how an element/component looks in a given state

Start with state-styles

React is already managing the state of your components, this makes styles of state and behavior a natural fit for colocation with your component logic.

Instead of building components to render with conditional state-classes, consider adding state-styles directly:

// Typical component with state-classes
<li 
 className={classnames({ 'todo-list__item': true, 'is-complete': item.complete })} />


// Using inline-styles for state
<li className='todo-list__item'
 style={(item.complete) ? styles.complete : {}} />

Note that we're using a class to style appearance but no longer using any .is- prefixed class for state and behavior.

We can use Object.assign (ES6) or _.extend (underscore/lodash) to add support for multiple states:

// Supporting multiple-states with inline-styles
<li 'todo-list__item'
 style={Object.assign({}, item.complete && styles.complete, item.due && styles.due )}>

Customization and reusability

Now that we're using Object.assign it becomes very simple to make our component reusable with different styles. If we want to override the default styles, we can do so at the call-site with props, like so: <TodoItem dueStyle={ fontWeight: "bold" } />. Implemented like this:

<li 'todo-list__item'
 style={Object.assign({},
         item.due && styles.due,
         item.due && this.props.dueStyles)}>

Layout

Personally, I don't see compelling reason to inline layout styles. There are a number of great CSS layout systems out there. I'd just use one.

That said, don't add layout styles directly to your component. Wrap your components with layout components. Here's an example.

// This couples your component to the layout system
// It reduces the reusability of your component
<UserBadge
 className="col-xs-12 col-sm-6 col-md-8"
 firstName="Michael"
 lastName="Chan" />

// This is much easier to maintain and change
<div class="col-xs-12 col-sm-6 col-md-8">
  <UserBadge
   firstName="Michael"
   lastName="Chan" />
</div>

For layout support, I often try to design components to be 100% width and height.

Appearance

This is the most contentious area of the "inline-style" debate. Ultimately, it's up to the component your designing and the comfort of your team with JavaScript.

One thing is certain, you'll need the assistance of a library. Browser-states (:hover, :focus), and media-queries are painful in raw React.

I like Radium because the syntax for those hard parts is designed to model that of SASS.

Code organization

Often you'll see a style object outside of the module. For a todo-list component, it might look something like this:

var styles = {
  root: {
    display: "block"
  },
  item: {
    color: "black"

    complete: {
      textDecoration: "line-through"
    },

    due: {
      color: "red"
    }
  },
}

getter functions

Adding a bunch of style logic to your template can get a little messy (as seen above). I like to create getter functions to compute styles:

React.createClass({
  getStyles: function () {
    return Object.assign(
      {},
      item.props.complete && styles.complete,
      item.props.due && styles.due,
      item.props.due && this.props.dueStyles
    );
  },

  render: function () {
    return <li style={this.getStyles()}>{this.props.item}</li>
  }
});

Further watching

I discussed all of these in more detail at React Europe earlier this year: Inline Styles and when it's best to 'just use CSS'.

I'm happy to help as you make new discoveries along the way :) Hit me up -> @chantastic

For a histogram with integer x-values I ended up using

plt.hist(data, np.arange(min(data)-0.5, max(data)+0.5))
plt.xticks(range(min(data), max(data)))

The offset of 0.5 centers the bins on the x-axis values. The plt.xticks call adds a tick for every integer.

Here is a version of the answer in

Swift 5

// MARK: - Hiding Back Button

extension UINavigationItem {

    /// A Boolean value that determines whether the back button is hidden.
    ///
    /// When set to `true`, the back button is hidden when this navigation item
    /// is the top item. This is true regardless of the value in the
    /// `leftItemsSupplementBackButton` property. When set to `false`, the back button
    /// is shown if it is still present. (It can be replaced by values in either
    /// the `leftBarButtonItem` or `leftBarButtonItems` properties.) The default value is `false`.
    @IBInspectable var hideBackButton: Bool {
        get { hidesBackButton }
        set { hidesBackButton = newValue }
    }
}

Every navigation item of a view controller will have this new property in the top section of attributes inspector

<%= link_to "http://www.facebook.com/sharer.php?u=" + article_url(article, :text => article.title), :class => "btn btn-primary" do %>   <i class="fa fa-facebook">     Facebook Share    </i> <%end%> 

I am assuming that current_article_url is http://0.0.0.0:4567/link_to_title

The best way is to do:

var obj ={"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10"??:0,"11":0,"12":0} 
Object.entries(obj);

Calling entries, as shown here, will return [key, value] pairs, as the asker requested.

Alternatively, you could call Object.values(obj), which would return only values.

This is where jQuery really shines for ASP.Net developers. Lets say you have this ASP button:

When that renders, you can look at the source of the page and the id on it won't be btnAwesome, but $ctr001_btnAwesome or something like that. This makes it a pain in the butt to find in javascript. Enter jQuery.

$(document).ready(function() {
  $("input[id$='btnAwesome']").click(function() {
    // Do client side button click stuff here.
  });
});

The id$= is doing a regex match for an id ENDING with btnAwesome.

Edit:

Did you want the ajax call being called from the button click event on the client side? What did you want to call? There are a lot of really good articles on using jQuery to make ajax calls to ASP.Net code behind methods.

The gist of it is you create a static method marked with the WebMethod attribute. You then can make a call to it using jQuery by using $.ajax.

$.ajax({
  type: "POST",
  url: "PageName.aspx/MethodName",
  data: "{}",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(msg) {
    // Do something interesting here.
  }
});

I learned my WebMethod stuff from: http://encosia.com/2008/05/29/using-jquery-to-directly-call-aspnet-ajax-page-methods/

A lot of really good ASP.Net/jQuery stuff there. Make sure you read up about why you have to use msg.d in the return on .Net 3.5 (maybe since 3.0) stuff.

There are some good resources for ramping up on crypto. Here's one:

• http://research.microsoft.com/en-us/groups/crypto/firstcrypto.aspx

From that page:

In the most commonly used public-key cryptography system, invented by Ron Rivest, Adi Shamir, and Len Adleman in 1977, both the public and the private keys are derived from a pair of large prime numbers according to a relatively simple mathematical formula. In theory, it might be possible to derive the private key from the public key by working the formula backwards. But only the product of the large prime numbers is public, and factoring numbers of that size into primes is so hard that even the most powerful supercomputers in the world cant break an ordinary public key.

Bruce Schneier's book Applied Cryptography is another. I highly recommend that book; it's fun reading.
