If you are using C99 then you can use the _Bool type. No #includes are necessary. You do need to treat it like an integer, though, where 1 is true and 0 is false.

You can then define TRUE and FALSE.

_Bool this_is_a_Boolean_var = 1;


//or using it with true and false
#define TRUE 1
#define FALSE 0
_Bool var = TRUE;

Try specifying CC while configuring:

CC=/usr/bin/gcc ./configure --prefix=/usr/local/sphinx

Also check if your compiler produces executables. The following should produce an a.out:

echo "int main(){0;}" | gcc -x c -

alpha-channel is the only data of the image that Android uses for notification icons:

• alpha == 1: pixels show white
• alpha == 0: pixels show as the color you chose at Notification.Builder#setColor(int)

This is mentioned at https://developer.android.com/about/versions/android-5.0-changes.html :

The system ignores all non-alpha channels in action icons and in the main notification icon. You should assume that these icons will be alpha-only.

Almost all built-in drawables seem to be suitable alpha images for this, so you might use something like:

Notification.Builder.setColor(Color.RED)
                    .setSmallIcon(android.R.drawable.star_on)

but I'm still looking for the API doc that officially confirms that.

Tested on Android 22.

There isn't one built in, but it's simple to roll your own, as demonstrated here:

import operator
def prod(factors):
    return reduce(operator.mul, factors, 1)

See answers to this question:

Which Python module is suitable for data manipulation in a list?

Assuming you're using WinForms, as it was the first thing I did when I was starting C# you need to create an event to close this form.

Lets say you've got a button called myNewButton. If you double click it on WinForms designer you will create an event. After that you just have to use this.Close

    private void myNewButton_Click(object sender, EventArgs e) {
        this.Close();
    }

And that should be it.

The only reason for this not working is that your Event is detached from button. But it should create new event if old one is no longer attached when you double click on the button in WinForms designer.

This is old question but still my answer may help someone

For checking Java version in android studio version , simply open Terminal of Android Studio and type

java -version 

This will display java version installed in android studio

Surprised no one mentioned:

<select id="selectVehicle">

    </select>

$("#selectVehicle").change(function () {
     alert($(this).find(':selected').data("year"));
});

Here is the working example: https://jsfiddle.net/ed5axgvk/1/

I created this simple one a while back. The main challenge I had was to create a good build environment - a makefile that would compile and link/deploy everything without having to use the GUI. For the code, here is the header:

class AMLed
{
    private:
          uint8_t _ledPin;
          long _turnOffTime;

    public:
          AMLed(uint8_t pin);
          void setOn();
          void setOff();
          // Turn the led on for a given amount of time (relies
          // on a call to check() in the main loop()).
          void setOnForTime(int millis);
          void check();
};

And here is the main source

AMLed::AMLed(uint8_t ledPin) : _ledPin(ledPin), _turnOffTime(0)
{
    pinMode(_ledPin, OUTPUT);
}

void AMLed::setOn()
{
    digitalWrite(_ledPin, HIGH);
}

void AMLed::setOff()
{
    digitalWrite(_ledPin, LOW);
}

void AMLed::setOnForTime(int p_millis)
{
    _turnOffTime = millis() + p_millis;
    setOn();
}

void AMLed::check()
{
    if (_turnOffTime != 0 && (millis() > _turnOffTime))
    {
        _turnOffTime = 0;
        setOff();
    }
}

It's more prettily formatted here: http://amkimian.blogspot.com/2009/07/trivial-led-class.html

To use, I simply do something like this in the .pde file:

#include "AM_Led.h"

#define TIME_LED    12   // The port for the LED

AMLed test(TIME_LED);

Why does TypeError: 'list' object is not callable appear?

Explanation:

It is because you defined list as a variable before (i am pretty sure), so it would be a list, not the function anymore, that's why everyone shouldn't name variables functions, the below is the same as what you're doing now:

>>> [1,2,3]()
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    [1,2,3]()
TypeError: 'list' object is not callable
>>>  

So you need it to be the default function of list, how to detect if it is? just use:

>>> list
<class 'list'>
>>> list = [1,2,3]
>>> list
[1, 2, 3]
>>> list()
Traceback (most recent call last):
  File "<pyshell#4>", line 1, in <module>
    list()
TypeError: 'list' object is not callable
>>> 

How do i detect whether a variable name is a function? well, just simple see if it has a different color, or use a code like:

>>> 'list' in dir(__builtins__)
True
>>> 'blah' in dir(__builtins__)
False
>>> 

After this, you should know why does TypeError: 'list' object is not callable appear.

Okay, so now...

How to fix this TypeError: 'list' object is not callable error?

Code:

You have to either do __builtins__.list():

>>> list = [1,2,3]
>>> __builtins__.list()
[]
>>> 

Or use []:

>>> list = [1,2,3]
>>> []
[]
>>> 

Or remove list variable from memory:

>>> list = [1,2,3]
>>> del list
>>> list()
[]
>>> 

Or just rename the variable:

>>> lst = [1,2,3]
>>> list()
[]
>>> 

P.S. Last one is the most preferable i guess :-)

There are a whole bunch of solutions that work.

The problem with this method is, at least when running by bash.exe on Windows, that it will create a new process every time which will remain dormant.

ssh-agent bash -c 'ssh-add /somewhere/yourkey; git clone [email protected]:user/project.git'

If you want want to use that for syncig repo on schedule then you need to add "&& ssh-agent -k" at the end.

Something like:

ssh-agent bash -c 'ssh-add C:/Users/user/.ssh/your_key; git -C "C:\Path\to\your\repo" pull && ssh-agent -k' 

ssh-agent -k will kill the process when it's done.

The $ symbol simply invokes the jQuery library's selector functionality. So $("#Text") returns the jQuery object for the Text div which can then be modified.

Some people posted options for Linux and Mac, and the Windows (free) equivalent is, if you can deal with it globally:

Set Windows desktop appearance theme window background color. You can keep current/desired theme, just modify the background color of windows. By default, it is set to white. I change it to a shade of grey. I tried dark grey and black before, but then you have to change text font colors globally, and all that's painful.

But a simple shade of grey as background does the trick globally, works with any color text font as long as the shade of grey is not too dark.

It's not the best solution for all editors/IDEs, as I prefer black, but it's the next best free & global workaround on Windows.

I think it needs to be checked if any row is selected or not? The below code would check it:

var entityGrid = $("#EntitesGrid").data("kendoGrid");
            var selectedItem = entityGrid.dataItem(entityGrid.select());
            if (selectedItem != undefined)
                alert("The Row Is SELECTED");
            else
                alert("NO Row Is SELECTED")

Default entity property value

If you want to set a default entity property value, then you can initialize the entity field using the default value.

For instance, you can set the default createdOn entity attribute to the current time, like this:

@Column(
    name = "created_on"
)
private LocalDateTime createdOn = LocalDateTime.now();

Default column value using JPA

If you are generating the DDL schema with JPA and Hibernate, although this is not recommended, you can use the columnDefinition attribute of the JPA @Column annotation, like this:

@Column(
    name = "created_on", 
    columnDefinition = "DATETIME(6) DEFAULT CURRENT_TIMESTAMP"
)
@Generated(GenerationTime.INSERT)
private LocalDateTime createdOn;

The @Generated annotation is needed because we want to instruct Hibernate to reload the entity after the Persistence Context is flushed, otherwise, the database-generated value will not be synchronized with the in-memory entity state.

Instead of using the columnDefinition, you are better off using a tool like Flyway and use DDL incremental migration scripts. That way, you will set the DEFAULT SQL clause in a script, rather than in a JPA annotation.

Default column value using Hibernate

If you are using JPA with Hibernate, then you can also use the @ColumnDefault annotation, like this:

@Column(name = "created_on")
@ColumnDefault(value="CURRENT_TIMESTAMP")
@Generated(GenerationTime.INSERT)
private LocalDateTime createdOn;

Default Date/Time column value using Hibernate

If you are using JPA with Hibernate and want to set the creation timestamp, then you can use the @CreationTimestamp annotation, like this:

@Column(name = "created_on")
@CreationTimestamp
private LocalDateTime createdOn;

Homebrew users: you can get lsusb by installing usbutils formula from my tap:

brew install mikhailai/misc/usbutils

It installs the REAL lsusb based on Linux sources (version 007).

data = """a,b,c
d,e,f
g,h,i
j,k,l"""

print(data.split())       # ['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']

str.split, by default, splits by all the whitespace characters. If the actual string has any other whitespace characters, you might want to use

print(data.split("\n"))   # ['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']

Or as @Ashwini Chaudhary suggested in the comments, you can use

print(data.splitlines())

Some transportation protocols only allow alphanumerical characters to be transmitted. Just imagine a situation where control characters are used to trigger special actions and/or that only supports a limited bit width per character. Base64 transforms any input into an encoding that only uses alphanumeric characters, +, / and the = as a padding character.

My solution is not efficient but helped me in situation where the values (bank cheque numbers and wire transfer ref no.) were stored as varchar where some entries had alpha numeric values with them and I had to pad if length is smaller than 6 chars.

Thought to share if someone comes across same situation

declare @minlen int = 6
declare @str varchar(20)

set @str = '123'
select case when len(@str) < @minlen then REPLICATE('0',@minlen-len(@str))+@str else @str end
--Ans: 000123

set @str = '1234'
select case when len(@str) < @minlen then REPLICATE('0',@minlen-len(@str))+@str else @str end
--Ans: 001234

set @str = '123456'
select case when len(@str) < @minlen then REPLICATE('0',@minlen-len(@str))+@str else @str end
--Ans: 123456

set @str = '123456789'
select case when len(@str) < @minlen then REPLICATE('0',@minlen-len(@str))+@str else @str end
--Ans: 123456789

set @str = '123456789'
select case when len(@str) < @minlen then REPLICATE('0',@minlen-len(@str))+@str else @str end
--Ans: 123456789


set @str = 'NEFT 123456789'
select case when len(@str) < @minlen then REPLICATE('0',@minlen-len(@str))+@str else @str end
--Ans: NEFT 123456789

I've built a module that makes in-memory pagination incredibly simple.

It allows you to paginate by simply replacing ng-repeat with dir-paginate, specifying the items per page as a piped filter, and then dropping the controls wherever you like in the form of a single directive, <dir-pagination-controls>

To take the original example asked by Tomarto, it would look like this:

<ul class='phones'>
    <li class='thumbnail' dir-paginate='phone in phones | filter:searchBar | orderBy:orderProp | limitTo:limit | itemsPerPage: limit'>
            <a href='#/phones/{{phone.id}}' class='thumb'><img ng-src='{{phone.imageUrl}}'></a>
            <a href='#/phones/{{phone.id}}'>{{phone.name}}</a>
            <p>{{phone.snippet}}</p>
    </li>
</ul>

<dir-pagination-controls></dir-pagination-controls>

There is no need for any special pagination code in your controller. It's all handled internally by the module.

Look up CPUID for one option. There might be some issues with multi-CPU systems.

If you need path only this is the most straightforward way:

PathOnly = ThisWorkbook.Path

Use the unicode escape sequence. First you'll have to find the codepoint for the character you seek to replace (let's just say it is ABCD in hex):

str = str.replaceAll("\uABCD", "");

I suspect the error is caused by this:

foreach (KeyValuePair<int, int> kvp in rankings)

rankings is a dictionary, which is IEnumerable. By using it in a foreach loop, you're specifying that you want each KeyValuePair from the dictionary in a deferred manner. That is, the next KeyValuePair is not returned until your loop iterates again.

But you're modifying the dictionary inside your loop:

rankings[kvp.Key] = rankings[kvp.Key] + 4;

which isn't allowed...so you get the exception.

You could simply do this

foreach (KeyValuePair<int, int> kvp in rankings.ToArray())

Asynchronous action methods are useful when an action must perform several independent long running operations.

A typical use for the AsyncController class is long-running Web service calls.

Should my database calls be asynchronous ?

The IIS thread pool can often handle many more simultaneous blocking requests than a database server. If the database is the bottleneck, asynchronous calls will not speed up the database response. Without a throttling mechanism, efficiently dispatching more work to an overwhelmed database server by using asynchronous calls merely shifts more of the burden to the database. If your DB is the bottleneck, asynchronous calls won’t be the magic bullet.

You should have a look at 1 and 2 references

Derived from @PanagiotisKanavos comments:

Moreover, async doesn't mean parallel. Asynchronous execution frees a valuable threadpool thread from blocking for an external resource, for no complexity or performance cost. This means the same IIS machine can handle more concurrent requests, not that it will run faster.

You should also consider that blocking calls start with a CPU-intensive spinwait. During stress times, blocking calls will result in escalating delays and app pool recycling. Asynchronous calls simply avoid this

Also, make sure when you write the query involving the linked server, you include brackets like this:

SELECT * FROM [LinkedServer].[RemoteDatabase].[User].[Table]

I've found that at least on 2000/2005 the [] brackets are necessary, at least around the server name.

For me it was a simple case of specifying the path to the 'sdk' subfolder rather than the top level folder.

In my case I needed to input

/Users/Myusername/Documents/adt-bundle-mac-x86_64-20140321/sdk

instead of

/Users/Myusername/Documents/adt-bundle-mac-x86_64-20140321

  , assert = require('assert');

// Connection URL
//var url = 'mongodb://localhost:27017/myproject';
var url = 'mongodb://myuser:[email protected]:portNumber/databasename';

// Use connect method to connect to the server
MongoClient.connect(url, function(err, db) {
  assert.equal(null, err);
  console.log("Connected successfully to server");

  renameDBColumn(db, function() {
    db.close();
  });

});

//
// This function should be used for renaming a field for all documents
//
var renameDBColumn = function(db, callback) {
  // Get the documents collection
  console.log("renaming database column of table documents");
  //use the former way:
  remap = function (x) {
    if (x.oldColumnName){
      db.collection('documents').update({_id:x._id}, {$set:{"newColumnName":x.oldColumnName}, $unset:{"oldColumnName":1}});
    }

Open that file and find the "class": "sidebar_label: entry and add "font.size".

example:

    {
        "class": "sidebar_label",
        "color": [0, 0, 0],
        "font.bold": false,
        "font.size": 14

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

In single line to print the element or array.

print $_ for (@array);

NOTE: remember that $_ is internally referring to the element of @array in loop. Any changes made in $_ will reflect in @array; ex.

my @array = qw( 1 2 3 );
for (@array) {
        $_ = $_ *2 ;
}
print "@array";

output: 2 4 6

In MySQL and MariaDB, the ` (backtick) symbol is the same as the " symbol. You can use " when your SQL_MODE has ANSI_QUOTES enabled.

Using bash:

if [ "`mysql -u'USER' -p'PASSWORD' -se'USE $DATABASE_NAME;' 2>&1`" == "" ]; then
    echo $DATABASE_NAME exist
else
    echo $DATABASE_NAME doesn't exist
fi

The difference between static and instantiated methods and properties seem to be one of the biggest obstacles to those just starting out with OOP PHP in PHP 5.

The double colon operator (which is called the Paamayim Nekudotayim from Hebrew - trivia) is used when calling an object or property from a static context. This means an instance of the object has not been created yet.

The arrow operator, conversely, calls methods or properties that from a reference of an instance of the object.

Static methods can be especially useful in object models that are linked to a database for create and delete methods, since you can set the return value to the inserted table id and then use the constructor to instantiate the object by the row id.

Bootstrap 4 (4.0.0-alpha.2) uses the css property column-count in the card-columns class to define how many columns of cards would be displayed inside the div element.
But this property has only two values:

• The default value 1 for small screens (max-width: 34em)
• The value 3 for all other sizes (min-width: 34em)

Here's how it is implemented in bootstrap.min.css :

@media (min-width: 34em) {
    .card-columns {
        -webkit-column-count:3;
        -moz-column-count:3;
        column-count:3;
        ?
    }
    ?
}

To make the card stacking responsive, you can add the following media queries to your css file and modify the values for min-width as per your requirements :

@media (min-width: 34em) {
    .card-columns {
        -webkit-column-count: 2;
        -moz-column-count: 2;
        column-count: 2;
    }
}

@media (min-width: 48em) {
    .card-columns {
        -webkit-column-count: 3;
        -moz-column-count: 3;
        column-count: 3;
    }
}

@media (min-width: 62em) {
    .card-columns {
        -webkit-column-count: 4;
        -moz-column-count: 4;
        column-count: 4;
    }
}

@media (min-width: 75em) {
    .card-columns {
        -webkit-column-count: 5;
        -moz-column-count: 5;
        column-count: 5;
    }
}

Create a separate ul.nav for just that list item and float that ul right.

jsFiddle

For example your file contains :

 1.  mangesh@001:~$ cat output.txt
    1
    2
    EOF

if u want to append at end of file then ---->remember spaces between 'text' >> 'filename'

  2. mangesh@001:~$ echo somthing to append >> output.txt|cat output.txt 
    1
    2
    EOF
    somthing to append

And to overwrite contents of file :

  3.  mangesh@001:~$ echo 'somthing new to write' > output.tx|cat output.tx
    somthing new to write

for example we have a

class Employee

{

int getsalary()

{return 0;}

String getDesignation()

{

return “default”;

}

}

class Manager extends Employee

{

int getsalary()

{

return 20000;

}

String getDesignation()

{

return “Manager”

}

}

class SoftwareEngineer extends Employee

{

int getsalary()

{

return 20000;

}

String getDesignation()

{

return “Manager”

}

}

now if you want to set or get salary and designation of all employee (i.e software enginerr,manager etc )

we will take an array of Employee and call both method getsalary(),getDesignation

Employee arr[]=new Employee[10];

arr[1]=new SoftwareEngieneer();

arr[2]=new Manager();

arr[n]=…….

for(int i;i>arr.length;i++)

{

System.out.println(arr[i].getDesignation+””+arr[i].getSalary())

}

now its an kind of loose coupling because you can have different types of employees ex:softeware engineer,manager,hr,pantryEmployee etc

so you can give object to the parent reference irrespective of different employee object

<div class="headerdivider"></div>

and

.headerdivider {
    border-left: 1px solid #38546d;
    background: #16222c;
    width: 1px;
    height: 80px;
    position: absolute;
    right: 250px;
    top: 10px;
}

You could use Microsoft.AspNetCore.Mvc.ControllerBase.StatusCode and Microsoft.AspNetCore.Http.StatusCodes to form your response, if you don't wish to hardcode specific numbers.

return  StatusCode(StatusCodes.Status500InternalServerError);

UPDATE: Aug 2019

Perhaps not directly related to the original question but when trying to achieve the same result with Microsoft Azure Functions I found that I had to construct a new StatusCodeResult object found in the Microsoft.AspNetCore.Mvc.Core assembly. My code now looks like this;

return new StatusCodeResult(StatusCodes.Status500InternalServerError);

This one-liner is pretty much the same as your original try with a couple of additions. It works with paths including spaces, and works in both XP and Windows 7 even if the key is not found (and hides the error). %fn% will be empty if the key does not exist. This example gets the current desktop background filename:

for /f "tokens=2*" %%a in ('reg query "HKEY_CURRENT_USER\Control Panel\Desktop" /v Wallpaper 2^>^&1^|find "REG_"') do @set fn=%%b

This command uses tokens=2* with %%a as the loop variable but consumes %%b to correctly handle spaces. When using tokens=2*, the loop variable %%a is assigned the value in the second token (in this case, REG_SZ) and %%b is assigned the remainder of the line after the next group of delimiter characters, including all internal delimiter characters. This means that %%b will correctly replicate delimiter characters—even if multiple delimiter characters are clustered together. For example, the value might be C:\A weird path\blah.png. This technique of reading the value would correctly preserve the two spaces between C:\A and weird.

list = [1,1,1,0]
print(any(list)) # will return True because there is  1 or True exists
print(all(list)) # will return False because there is a 0 or False exists
return all(a % i for i in range(3, int(a ** 0.5) + 1)) # when number is divisible it will return False else return True but the whole statement is False .

There are various ways to do this and various redirects, I've listed them below:

301 (Permanent) Redirect: Point an entire site to a different URL on a permanent basis. This is the most common type of redirect and is useful in most situations. In this example, we are redirecting to the "example.com" domain:

# This allows you to redirect your entire website to any other domain
Redirect 301 / http://example.com/

302 (Temporary) Redirect: Point an entire site to a different temporary URL. This is useful for SEO purposes when you have a temporary landing page and plan to switch back to your main landing page at a later date:

# This allows you to redirect your entire website to any other domain
Redirect 302 / http://example.com/

Redirect index.html to a specific subfolder:

# This allows you to redirect index.html to a specific subfolder
Redirect /index.html http://example.com/newdirectory/

Redirect an old file to a new file path:

# Redirect old file path to new file path
Redirect /olddirectory/oldfile.html http://example.com/newdirectory/newfile.html

Redirect to a specific index page:

# Provide Specific Index Page (Set the default handler)
DirectoryIndex index.html

1) Setting the first Panel:

JFrame frame=new JFrame();
frame.getContentPane().add(new JPanel());

2)Replacing the panel:

frame.getContentPane().removeAll();
frame.getContentPane().add(new JPanel());

Also notice that you must do this in the Event's Thread, to ensure this use the SwingUtilities.invokeLater or the SwingWorker

I ran into this today (mysql 2.16.0) and thought I'd share my solution:

const items = [
    {name: 'alpha', description: 'describes alpha', value: 1},
    ...
];

db.query(
    'INSERT INTO my_table (name, description, value) VALUES ?',
    [items.map(item => [item.name, item.description, item.value])],
    (error, results) => {...}
);

It seems to be a browser bug.

End your current session and open another session in tool like mobiXterm. Make sure session has X11 forwarding enabled in the tool.

Use this:

Dictionary<TKey, Tuple<TValue1, TValue2, TValue3, ...>>

the discussion and answer here was massively helpful to me:

psql: FATAL: database "<user>" does not exist

I think basic solutions to the question should be as below:

Supplier supplier=HashSet::new; 
HashSet has=ls.stream().collect(Collectors.toCollection(supplier));

List lst = (List) ls.stream().filter(e->Collections.frequency(ls,e)>1).distinct().collect(Collectors.toList());

well, it is not recommended to perform a filter operation, but for better understanding, i have used it, moreover, there should be some custom filtration in future versions.

In the comments in the answer, it does not explicitly state that nextTick shifted from Macrosemantics to Microsemantics.

before node 0.9 (when setImmediate was introduced), nextTick operated at the start of the next callstack.

since node 0.9, nextTick operates at the end of the existing callstack, whereas setImmediate is at the start of the next callstack

I was not able to get this working entirely based on the suggestions above. Including the DataTypeAttribute [DataType(DataType.Date)] seemed to solve my issue, see:

Judging by the source code for URI, the

public URL(URL context, String spec, URLStreamHandler handler)

constructor does more validation than the other constructors. You might try that one, but YMMV.

You need to set option CURLOPT_PROXYTYPE to CURLPROXY_SOCKS5_HOSTNAME, which sadly wasn't defined in old PHP versions, circa pre-5.6; if you have earlier in but you can explicitly use its value, which is equal to 7:

curl_setopt($ch, CURLOPT_PROXYTYPE, 7);

You can use the object-fit property to size the img elements:

• cover stretches or shrinks the image proportionally to fill the container. The image is cropped horizontally -or- vertically if necessary.
• contain stretches or shrinks the image proportionally to fit inside the container.
• scale-down shrinks the image proportionally to fit inside the container.

.example {_x000D_
  margin: 1em 0;_x000D_
  text-align: center;_x000D_
}_x000D_

For a small enum like this, I find the most readable solution to be:

public enum Direction {

    NORTH {
        @Override
        public Direction getOppositeDirection() {
            return SOUTH;
        }
    }, 
    SOUTH {
        @Override
        public Direction getOppositeDirection() {
            return NORTH;
        }
    },
    EAST {
        @Override
        public Direction getOppositeDirection() {
            return WEST;
        }
    },
    WEST {
        @Override
        public Direction getOppositeDirection() {
            return EAST;
        }
    };


    public abstract Direction getOppositeDirection();

}

As I am new, I can't comment on other answers.

If someone is looking for an answer to make this work (and can use javascript - as it seems to be required to make this work at the moment) this approach has worked pretty well for me and it accounts for mobile orientation change as well. I use Jquery for the example code but should be doable with vanillaJS.

-First, I use a script to detect if the device is touch or hover. Bare-bones example:

if ("ontouchstart" in document.documentElement) {
    document.body.classList.add('touch-device');

} else {
    document.body.classList.add('hover-device');
}

This adds class to the body element according to the device type (hover or touch) that can be used later for the height script.

-Next use this code to set height of the device on load and on orientation change:

if (jQuery('body').hasClass("touch-device")) {
//Loading height on touch-device
    function calcFullHeight() {
        jQuery('.hero-section').css("height", $(window).height());
    }

    (function($) {
        calcFullHeight();

        jQuery(window).on('orientationchange', function() {
            // 500ms timeout for getting the correct height after orientation change
            setTimeout(function() {
                calcFullHeight();
            }, 500);

        });
    })(jQuery);

} else {
    jQuery('.hero-section').css("height", "100vh");


}

-Timeout is set so that the device would calculate the new height correctly on orientation change. If there is no timeout, in my experience the height will not be correct. 500ms might be an overdo but has worked for me.

-100vh on hover-devices is a fallback if the browser overrides the CSS 100vh.

The second parameter passed to Geolocation.getCurrentPosition() is the function you want to handle any geolocation errors. The error handler function itself receives a PositionError object with details about why the geolocation attempt failed. I recommend outputting the error to the console if you have any issues:

var positionOptions = { timeout: 10000 };
navigator.geolocation.getCurrentPosition(updateLocation, errorHandler, positionOptions);
function updateLocation(position) {
  // The geolocation succeeded, and the position is available
}
function errorHandler(positionError) {
  if (window.console) {
    console.log(positionError);
  }
}

Doing this in my code revealed the message "Network location provider at 'https://www.googleapis.com/' : Returned error code 400". Turns out Google Chrome uses the Google APIs to get a location on devices that don't have GPS built in (for example, most desktop computers). Google returns an approximate latitude/longitude based on the user's IP address. However, in developer builds of Chrome (such as Chromium on Ubuntu) there is no API access key included in the browser build. This causes the API request to fail silently. See Chromium Issue 179686: Geolocation giving 403 error for details.

Its extremely easy! Create a file that contains:

call <filename>  // the file you made
cls
echo An error occured!
<Your commands>
pause

So now when you start it, it will launch your program as normal. But when anything goes wrong it exits and continues the script inside the first file. Now there you can put your own commands in.

You could encode the binary data using base64 and put it into a Base64 element; the below article is a pretty good one on the subject.

Handling Binary Data in XML Documents

Try this:

$results = DB::table('users')->toSql();
dd($results);

Note: get() has been replaced with toSql() to display the raw SQL query.

The glyphicons.less file from Bootstrap 3 is available on GitHub. https://github.com/twbs/bootstrap/blob/master/less/glyphicons.less

It needs these variables:

@icon-font-path:          "../fonts/";
@icon-font-name:          "glyphicons-halflings-regular";
@icon-font-svg-id:        "glyphicons_halflingsregular";

Then you can convert the .less file to a .css file which you can use directly. You can do this online on lesscss.org/less-preview/. Here I've done it for you, save it as glyphicons.css and include it in your HTML files.

<link href="/Content/glyphicons.css" rel="stylesheet" />

You also need the Glyphicon fonts which is in the Bootstrap 3 package, place them in a /fonts/ directory.

Now you can just keep on using Glyphicons with Bootstrap 4 as usual.

Tried @freddoo solution but it didn't work for 1 minute timeouts so I've changed it slightly to record the date+time when the user last clicked on the page and in my timerIncrement function I calculate the difference between the current time and the last clicked time and if the value happens to be bigger or equal to the timeout value then I redirect:

var clickedDate = new Date();
var idleTime = 1;//

function timerIncrement() {

    var nowDate = new Date();
    var diffMs = (nowDate - clickedDate); //Milliseconds between now & the last time a user clicked somewhere on the page
    var diffMins = Math.round(((diffMs % 86400000) % 3600000) / 60000); //Convert ms to minutes

    if (diffMins >= idleTime) {
        //Redirect user to home page etc...
    }
}

$(document).ready(function () {

    var idleInterval = setInterval(timerIncrement, 60000); // 1 minute

    $(this).click(function (e) {
        clickedDate = new Date();
    });

});

You need to use an undocumented trick with Excel's LINEST function:

=LINEST(known_y's, [known_x's], [const], [stats])

Background

A regular linear regression is calculated (with your data) as:

=LINEST(B2:B21,A2:A21)

which returns a single value, the linear slope (m) according to the formula:

which for your data:

is:

Undocumented trick Number 1

You can also use Excel to calculate a regression with a formula that uses an exponent for x different from 1, e.g. x^1.2:

using the formula:

=LINEST(B2:B21, A2:A21^1.2)

which for you data:

is:

You're not limited to one exponent

Excel's LINEST function can also calculate multiple regressions, with different exponents on x at the same time, e.g.:

=LINEST(B2:B21,A2:A21^{1,2})

Note: if locale is set to European (decimal symbol ","), then comma should be replaced by semicolon and backslash, i.e. =LINEST(B2:B21;A2:A21^{1\2})

Now Excel will calculate regressions using both x¹ and x² at the same time:

How to actually do it

The impossibly tricky part there's no obvious way to see the other regression values. In order to do that you need to:

• select the cell that contains your formula:

  

• extend the selection the left 2 spaces (you need the select to be at least 3 cells wide):

  

• press F2

• press Ctrl+Shift+Enter

  

You will now see your 3 regression constants:

  y = -0.01777539x^2 + 6.864151123x + -591.3531443

Bonus Chatter

I had a function that I wanted to perform a regression using some exponent:

y = m×x^k + b

But I didn't know the exponent. So I changed the LINEST function to use a cell reference instead:

=LINEST(B2:B21,A2:A21^F3, true, true)

With Excel then outputting full stats (the 4th paramter to LINEST):

I tell the Solver to maximize R²:

And it can figure out the best exponent. Which for you data:

is:

I figured out below would work:

my_df.dropna().quantile([0.0, .9])

It is work, I hope help you

.btn:focus, .btn:focus:active {
    outline: none;
}

My proposal without ugly "foreach" control structures is

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));
$allFiles = array_filter(iterator_to_array($iterator), function($file) {
    return $file->isFile();
});

You may only want to extract the filepath, which you can do so by:

array_keys($allFiles);

Still 4 lines of code, but more straight forward than using a loop or something.

How about using asp:LinkButton?

From the jQuery :input selector page:

Because :input is a jQuery extension and not part of the CSS specification, queries using :input cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :input to select elements, first select the elements using a pure CSS selector, then use .filter(":input").

This is the best choice.

$('#new_user_form *').filter(':input').each(function(){
    //your code here
});

As second says, most of the "design" decisions made for TeX documents are backed up by well researched usability studies, so changing them should be undertaken with care. It is, however, relatively common to replace Computer Modern with Times (also a serif face).

Try \usepackage{times}.

Without regex:

str = str.split("\n").join("<br />");

So does C99.

The IEEE 754 floating point representation used by all modern processors has several special bit patterns reserved for positive infinity (sign=0, exp=~0, frac=0), negative infinity (sign=1, exp=~0, frac=0), and many NaN (Not a Number: exp=~0, frac?0).

All you need to worry about: some arithmetic may cause floating point exceptions/traps, but those aren't limited to only these "interesting" constants.

You can also use simple_format(@str) which removes malicious code. Read more here: http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-simple_format

The easiest method is really good but you don't get a standard Java project, i.e., the .java and .class files separated in different folders.

To get this very easily:

1. Create a folder called "ProjectName" on the workspace of Eclipse.
2. Copy or move your folder with the .java files to the "ProjectName" folder.
3. Create a new Java Project called "ProjectName" (with the Use default location marked).
4. Press <Enter> and that's it.

class MyParent:

    def sayHi():
        print('Mamma says hi')

from path.to.MyParent import MyParent

class ChildClass(MyParent):
    pass

An instance of ChildClass will then inherit the sayHi() method.

It just needs to be in the classpath (aka make sure it ends up under /WEB-INF/classes in the .war as part of the build).

In any case, you can override height with max-height.

I have an solution for a generic List<> with dynamic binded items.

class PersonalList it's the root element

        this.Listname = name;
    }

    public void AddPerson(Person person)
    {
        Persons.Add(person);
    }
}

class Person it's an single list element

[XmlType("Person")] // define Type

        {
            this.Skills.Add(item);   
        }
        this.Alias = alias;

Important is the definition and includes of the diffrent types.

In Java8:

LongSummaryStatistics movingAverage = new LongSummaryStatistics();
movingAverage.accept(new data);
...
average = movingAverage.getAverage();

you have also IntSummaryStatistics, DoubleSummaryStatistics ...

Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.

However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown event to block key input before it displays on the screen.

I fixed this error by simply switching from Debug to Release, launch program (It worked on release), then switch back to Debug.

I tried just about everything else, including restarting Visual Studio and nothing worked.

Portmon from sysinternals (now MSFT) is probably the best monitor.

I haven't found a good free tool that will emulate a port and record/replay comms. The commercial ones were expensive and either so limited or so complex if you want to respond to commands that I ended up using expect and python on a second machine.

I faced this issue once and was able to resolve it by fixing of my /etc/hosts. It just was unable to resolve localhost name... Details are here: http://itvictories.com/node/6

In fact, there is 99% that error related to /etc/hosts file

X server just unable to resolve localhost and all consequent actions just fails.

Please be sure that you have a record like

127.0.0.1 localhost

in your /etc/hosts file.

Use the document.createElement function and then add it as a child of your select.

var newOption = document.createElement("option");
newOption.text = 'the options text';
newOption.value = 'some value if you want it';
daySelect.appendChild(newOption);

if you are in windows try this

 docker-machine env --shell cmd default 
 @FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO @%i

for testing try

docker run hello-world

Try to add the suggested code to the TextChanged event:

private void textBox1_TextChanged(object sender, EventArgs e)
{
  textBox1.SelectionStart = textBox1.Text.Length;
  textBox1.ScrollToCaret();
}

In the target's General tab, there is a section called Frameworks, Libraries, and Embedded Content

Click on the + sign, add required framework and the crash is resolved.

You can try

WebElement navigationPageButton = (new WebDriverWait(driver, 10))
 .until(ExpectedConditions.presenceOfElementLocated(By.id("navigationPageButton")));
navigationPageButton.click();

An alternative to type -a is command -V

Since most of the times I am interested in the first result only, I also pipe from head. This way the screen will not flood with code in case of a bash function.

command -V lshw | head -n1

UPDATE TABLE_NAME SET COLUMN_A = COLUMN_B;

Much easier. At least on Oracle SQL, i don't know if this works on other dialects as well.

if x is a vector with raw scores then scale(x) is a vector with standardized scores.

Or manually: (x-mean(x))/sd(x)

Best way to do it

Regardless of what your object is and for what table in the database the only thing you need to have is the primary key in the object.

C# Code

var dbValue = EntityObject.Entry(obj).GetDatabaseValues();
if (dbValue == null)
{
   Don't exist
}

VB.NET Code

Dim dbValue = EntityObject.Entry(obj).GetDatabaseValues()
If dbValue Is Nothing Then
   Don't exist
End If

pip is designed to upgrade python packages and not to upgrade python itself. pip shouldn't try to upgrade python when you ask it to do so.

Don't type pip install python but use an installer instead.

You can try this:

public enum Modes {
    some-really-long-string,
    mode1,
    mode2,
    mode3;

    public String toString(){
        switch(this) {
            case some-really-long-string:
                return "some-really-long-string";
            case mode2:
                return "mode2";
            default: return "undefined";
        }
    }

}

Have you tried .editorconfig? You can create this file in the root of your project and configure indentation for different file types. Your code will be automatically formatted. Here's the example:

# top-most EditorConfig file
root = true

# matches all files
[*]
indent_style = tab
indent_size = 4

# only json
[*.json]
indent_style = space
indent_size = 2

'Ctrl + m' works for Windows in the Android emulator to bring up the React-Native developer menu.

Couldn't find that documented anywhere. Found my way here, guessed the rest... Good grief.

By the way: OP: You didn't mention what OS you were on.

just use CustomEvent

Node.prototype.fire=function(type,options){
     var event=new CustomEvent(type);
     for(var p in options){
         event[p]=options[p];
     }
     this.dispatchEvent(event);
}

4 ex want to simulate ctrl+z

window.addEventListener("keyup",function(ev){
     if(ev.ctrlKey && ev.keyCode === 90) console.log(ev); // or do smth
     })

 document.fire("keyup",{ctrlKey:true,keyCode:90,bubbles:true})

Make the code say if (msg.content === ('trigger') msg.author.send('text')}

You have to implement KeyListener,take a look here: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyListener.html

More details on how to use it: http://docs.oracle.com/javase/tutorial/uiswing/events/keylistener.html

Your function has a couple of smallint parameters.
But in the call, you are using numeric literals that are presumed to be type integer.

A string literal or string constant ('123') is not typed immediately. It remains type "unknown" until assigned or cast explicitly.

However, a numeric literal or numeric constant is typed immediately. Per documentation:

A numeric constant that contains neither a decimal point nor an exponent is initially presumed to be type integer if its value fits in type integer (32 bits); otherwise it is presumed to be type bigint if its value fits in type bigint (64 bits); otherwise it is taken to be type numeric. Constants that contain decimal points and/or exponents are always initially presumed to be type numeric.

More explanation and links in this related answer:

• PostgreSQL ERROR: function to_tsvector(character varying, unknown) does not exist

Solution

Add explicit casts for the smallint parameters or quote them.

Demo

CREATE OR REPLACE FUNCTION f_typetest(smallint)
  RETURNS bool AS 'SELECT TRUE' LANGUAGE sql;

Incorrect call:

SELECT * FROM f_typetest(1);

Correct calls:

SELECT * FROM f_typetest('1');
SELECT * FROM f_typetest(smallint '1');
SELECT * FROM f_typetest(1::int2);
SELECT * FROM f_typetest('1'::int2);

add HeaderStyle in your bound field:

    <asp:BoundField HeaderText="UserId"
                DataField="UserId" 
                SortExpression="UserId">

                <HeaderStyle Width="200px" />

</asp:BoundField>

This issue only happens in Android emulators. I also faced this issue in an emulator but when I checked in a device then it worked fine.

So please check in a device. It may be run in device.

You can use the CheckedChanged event for all your RadioButtons. Sender will be the unchecked and checked RadioButtons.

Much longer solution, but accounts for the following scenarios:

1. Is the image smaller than the bounding box?
2. Is the Image and the Bounding Box square?
3. Is the Image square and the bounding box isn't
4. Is the image wider and taller than the bounding box
5. Is the image wider than the bounding box

6. Is the image taller than the bounding box

   private Image ResizePhoto(FileInfo sourceImage, int desiredWidth, int desiredHeight)

       if (desiredWidth < 4 || desiredHeight < 4)
           throw new InvalidOperationException("Bounding Box of Resize Photo must be larger than 4X4 pixels.");

           Bitmap square = new Bitmap(original, smallSide, smallSide);
           original.Dispose();

You have to be careful while changing factors to numeric. Here is a line of code that would change a set of columns from factor to numeric. I am assuming here that the columns to be changed to numeric are 1, 3, 4 and 5 respectively. You could change it accordingly

cols = c(1, 3, 4, 5);    
df[,cols] = apply(df[,cols], 2, function(x) as.numeric(as.character(x)));

I have extended cletus proposed answer to working code example.

1. One ExecutorService (pes) accepts Producer tasks.
2. One ExecutorService (ces) accepts Consumer tasks.
3. Both Producer and Consumer shares BlockingQueue.
4. Multiple Producer tasks generates different numbers.
5. Any of Consumer tasks can consume number generated by Producer

Code:

import java.util.concurrent.*;

public class ProducerConsumerWithES {
    public static void main(String args[]){
         BlockingQueue<Integer> sharedQueue = new LinkedBlockingQueue<Integer>();

         ExecutorService pes = Executors.newFixedThreadPool(2);
         ExecutorService ces = Executors.newFixedThreadPool(2);

         pes.submit(new Producer(sharedQueue,1));
         pes.submit(new Producer(sharedQueue,2));
         ces.submit(new Consumer(sharedQueue,1));
         ces.submit(new Consumer(sharedQueue,2));
         // shutdown should happen somewhere along with awaitTermination
         / * https://stackoverflow.com/questions/36644043/how-to-properly-shutdown-java-executorservice/36644320#36644320 */
         pes.shutdown();
         ces.shutdown();
    }
}
class Producer implements Runnable {
    private final BlockingQueue<Integer> sharedQueue;
    private int threadNo;
    public Producer(BlockingQueue<Integer> sharedQueue,int threadNo) {
        this.threadNo = threadNo;
        this.sharedQueue = sharedQueue;
    }
    @Override
    public void run() {
        for(int i=1; i<= 5; i++){
            try {
                int number = i+(10*threadNo);
                System.out.println("Produced:" + number + ":by thread:"+ threadNo);
                sharedQueue.put(number);
            } catch (Exception err) {
                err.printStackTrace();
            }
        }
    }
}

class Consumer implements Runnable{
    private final BlockingQueue<Integer> sharedQueue;
    private int threadNo;
    public Consumer (BlockingQueue<Integer> sharedQueue,int threadNo) {
        this.sharedQueue = sharedQueue;
        this.threadNo = threadNo;
    }
    @Override
    public void run() {
        while(true){
            try {
                int num = sharedQueue.take();
                System.out.println("Consumed: "+ num + ":by thread:"+threadNo);
            } catch (Exception err) {
               err.printStackTrace();
            }
        }
    }   
}

output:

Note. If you don't need multiple Producers and Consumers, keep single Producer and Consumer. I have added multiple Producers and Consumers to showcase capabilities of BlockingQueue among multiple Producers and Consumers.

Update (2017): The following two libraries have now become the most common drop-down libraries used with Javascript. While they are jQuery-native, they have been customized to work with everything from AngularJS 1.x to having custom CSS for Bootstrap. (Chosen JS, the original answer here, seems to have dropped to #3 in popularity.)

Original answer (2012): I think that the Chosen library might also be useful. Its available in jQuery, Prototype and MooTools versions.

Attached is a screenshot of how the multi-select functionality looks in Chosen.

Here's an extension method for converting a Bitmap to BitmapImage.

    public static BitmapImage ToBitmapImage(this Bitmap bitmap)
    {
        using (var memory = new MemoryStream())
        {
            bitmap.Save(memory, ImageFormat.Png);
            memory.Position = 0;

            var bitmapImage = new BitmapImage();
            bitmapImage.BeginInit();
            bitmapImage.StreamSource = memory;
            bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
            bitmapImage.EndInit();
            bitmapImage.Freeze();

            return bitmapImage;
        }
    }

HTTPS using Jersey client has two different version if you are using java 6 ,7 and 8 then

SSLContext sc = SSLContext.getInstance("SSL");

If using java 8 then

SSLContext sc = SSLContext.getInstance("TLSv1");
System.setProperty("https.protocols", "TLSv1");

Once you start running application will get Certificate error ,download certificate from browser and add into

C:\java-8\jdk1_8_0\jre\lib\security

Add into cacerts , you will get details in following links.

Few useful link to understand error

• http://www.9threes.com/2015/01/restful-java-client-with-jersey-client.html

  Java: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

  http://magicmonster.com/kb/prg/java/ssl/pkix_path_building_failed.html

  Java Keytool error after importing certificate , "keytool error: java.io.FileNotFoundException & Access Denied"

I have tested following code for get and post method with SSL and basic Authentication here you can skip SSL Certificate , you can directly copy three class and add jar into java project and run.

In case that you need to turn on and off the listener multiple times, you can create a function with boolean parameter

function switchListen(_switch) {
    if (_switch) {
      $scope.$on("onViewUpdated", this.callMe);
    } else {
      $rootScope.$$listeners.onViewUpdated = [];
    }
}

You can encode it in PHP :)

<img src="data:image/gif;base64,<?php echo base64_encode(file_get_contents("feed-icon.gif")); ?>">

Or display in our dynamic CSS.php file:

background: url("data:image/gif;base64,<?php echo base64_encode(file_get_contents("feed-icon.gif")); ?>");

1 That’s sort of a “quick-n-dirty” technique but it works. Here is another encoding method using fopen() instead of file_get_contents():

<?php // convert image to dataURL
$img_source = "feed-icon.gif"; // image path/name
$img_binary = fread(fopen($img_source, "r"), filesize($img_source));
$img_string = base64_encode($img_binary);
?>

Source

instead of csv, trying outputting html with an XLS extension and "application/excel" mime-type. I know this will work in Windows, but can't speak for MacOS

Note: The placement of cross_origin should be right and dependencies are installed. On the client side, ensure to specify kind of data server is consuming. For example application/json or text/html

For me the code written below did magic

from flask import Flask,request,jsonify
from flask_cors import CORS,cross_origin
app=Flask(__name__)
CORS(app, support_credentials=True)
@app.route('/api/test', methods=['POST', 'GET','OPTIONS'])
@cross_origin(supports_credentials=True)
def index():
    if(request.method=='POST'):
     some_json=request.get_json()
     return jsonify({"key":some_json})
    else:
        return jsonify({"GET":"GET"})


if __name__=="__main__":
    app.run(host='0.0.0.0', port=5000)

Try this code, works 100% for me:
FOR Landscape:

<head>
<style type="text/css">

@page{
  size: auto A4 landscape;
  margin: 3mm;
}

</style>
</head>

FOR Portait:

<head>
<style type="text/css">

@page{
  size: auto;
  margin: 3mm;
}

</style>
</head>

You should check out Apache's commons-io. It has a FileUtils class that will do what you want.

FileUtils.deleteDirectory(new File("directory"));

Look at strtok(). strtok() is not a re-entrant function.

strtok_r() is the re-entrant version of strtok(). Here's an example program from the manual:

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

   int main(int argc, char *argv[])
   {
       char *str1, *str2, *token, *subtoken;
       char *saveptr1, *saveptr2;
       int j;

       if (argc != 4) {
           fprintf(stderr, "Usage: %s string delim subdelim\n",argv[0]);
           exit(EXIT_FAILURE);
       }

       for (j = 1, str1 = argv[1]; ; j++, str1 = NULL) {
           token = strtok_r(str1, argv[2], &saveptr1);
           if (token == NULL)
               break;
           printf("%d: %s\n", j, token);

           for (str2 = token; ; str2 = NULL) {
               subtoken = strtok_r(str2, argv[3], &saveptr2);
               if (subtoken == NULL)
                   break;
               printf(" --> %s\n", subtoken);
           }
       }

       exit(EXIT_SUCCESS);
   }

Sample run which operates on subtokens which was obtained from the previous token based on a different delimiter:

$ ./a.out hello:word:bye=abc:def:ghi = :

1: hello:word:bye
 --> hello
 --> word
 --> bye
2: abc:def:ghi
 --> abc
 --> def
 --> ghi

You can easily use:

string.count('test')!

https://www.programiz.com/python-programming/methods/string/count

Cheers!

Xenph Yan's answer was far cleaner than mine but here is mine all the same.

DECLARE @startStr AS Varchar (20)
SET @startStr = 'tableName'

DECLARE @startStrLen AS int
SELECT @startStrLen = LEN(@startStr)

SELECT 'DROP TABLE ' + name FROM sysobjects
WHERE type = 'U' AND LEFT(name, @startStrLen) = @startStr

Just change tableName to the characters that you want to search with.

This worked for me:

string string_test = "80123456";
unsigned long x;
signed long val;

std::stringstream ss;
ss << std::hex << string_test;
ss >> x;
// ss >> val;  // if I try this val = 0
val = (signed long)x;  // However, if I cast the unsigned result I get val = 0x80123456 

Here is a full example, using std::move for a (simple) custom vector

Expected output:

 c: [10][11]
 copy ctor called
 copy of c: [10][11]
 move ctor called
 moved c: [10][11]

Compile as:

  g++ -std=c++2a -O2 -Wall -pedantic foo.cpp

Code:

#include <iostream>
#include <algorithm>

template<class T> class MyVector {
private:
    T *data;
    size_t maxlen;
    size_t currlen;
public:
    MyVector<T> () : data (nullptr), maxlen(0), currlen(0) { }
    MyVector<T> (int maxlen) : data (new T [maxlen]), maxlen(maxlen), currlen(0) { }

    MyVector<T> (const MyVector& o) {
        std::cout << "copy ctor called" << std::endl;
        data = new T [o.maxlen];
        maxlen = o.maxlen;
        currlen = o.currlen;
        std::copy(o.data, o.data + o.maxlen, data);
    }

    MyVector<T> (const MyVector<T>&& o) {
        std::cout << "move ctor called" << std::endl;
        data = o.data;
        maxlen = o.maxlen;
        currlen = o.currlen;
    }

    void push_back (const T& i) {
        if (currlen >= maxlen) {
            maxlen *= 2;
            auto newdata = new T [maxlen];
            std::copy(data, data + currlen, newdata);
            if (data) {
                delete[] data;
            }
            data = newdata;
        }
        data[currlen++] = i;
    }

    friend std::ostream& operator<<(std::ostream &os, const MyVector<T>& o) {
        auto s = o.data;
        auto e = o.data + o.currlen;;
        while (s < e) {
            os << "[" << *s << "]";
            s++;
        }
        return os;
    }
};

int main() {
    auto c = new MyVector<int>(1);
    c->push_back(10);
    c->push_back(11);
    std::cout << "c: " << *c << std::endl;
    auto d = *c;
    std::cout << "copy of c: " << d << std::endl;
    auto e = std::move(*c);
    delete c;
    std::cout << "moved c: " << e << std::endl;
}

SELECT count(*)         -- or count(myCol)
FROM   <table name>     -- replace <table name> with your table
WHERE  myCol = true;

Here's a way with Windowing Function:

SELECT DISTINCT *, count(*) over(partition by myCol)
FROM   <table name>;

-- Outputs:
-- --------------
-- myCol | count
-- ------+-------
--  f    |  2
--  t    |  3
--       |  1

Works that way as well, a bit more tidy. getQuery() just returns the underlying builder, which already contains the table reference.

$browser_total_raw = DB::raw('count(*) as total');
$user_info = Usermeta::getQuery()
                     ->select('browser', $browser_total_raw)
                     ->groupBy('browser')
                     ->pluck('total','browser');

I hope this will meet your requirement

import PyPDF4
import io

pdfFile = open(r'test.pdf', 'rb')
pdfReader = PyPDF4.PdfFileReader(pdfFile)
pageObj = pdfReader.getPage(1)
pagetext = pageObj.extractText()

for line in io.StringIO(pagetext):
    print(line)

The way I use it is

# Have to assign back to dataframe (because it is a new copy)
df = df.some_operation(inplace=False) 

Or

# No need to assign back to dataframe (because it is on the same copy)
df.some_operation(inplace=True)

CONCLUSION:

 if inplace is False
      Assign to a new variable;
 else
      No need to assign

Another way to do it that's designed for django, but should work in most settings, is to use django-dotenv.

I think np.isnan(np.min(X)) should do what you want.

Great answer of Josh, all credit to him, I slightly modified it to this however:

MyDialog Xaml

    <StackPanel Margin="5,5,5,5">
        <TextBlock Name="TitleTextBox" Margin="0,0,0,10" />
        <TextBox Name="InputTextBox" Padding="3,3,3,3" />
        <Grid Margin="0,10,0,0">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Button Name="BtnOk" Content="OK" Grid.Column="0" Margin="0,0,5,0" Padding="8" Click="BtnOk_Click" />
            <Button Name="BtnCancel" Content="Cancel" Grid.Column="1" Margin="5,0,0,0" Padding="8" Click="BtnCancel_Click" />
        </Grid>
    </StackPanel>

MyDialog Code Behind

    public MyDialog()
    {
        InitializeComponent();
    }

    public MyDialog(string title,string input)
    {
        InitializeComponent();
        TitleText = title;
        InputText = input;
    }

    public string TitleText
    {
        get { return TitleTextBox.Text; }
        set { TitleTextBox.Text = value; }
    }

    public string InputText
    {
        get { return InputTextBox.Text; }
        set { InputTextBox.Text = value; }
    }

    public bool Canceled { get; set; }

    private void BtnCancel_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Canceled = true;
        Close();
    }

    private void BtnOk_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Canceled = false;
        Close();
    }

And call it somewhere else

var dialog = new MyDialog("test", "hello");
dialog.Show();
dialog.Closing += (sender,e) =>
{
    var d = sender as MyDialog;
    if(!d.Canceled)
        MessageBox.Show(d.InputText);
}

I ran into this problem in a slightly different way from the other answers here.

If I simply created a new xib file, added a UIViewController to it in Interface Builder, and set that UIViewController's custom class to my view controller, that resulted in the "view outlet was not set" crash. The other solutions here say to control-drag the view outlet to the View, but for me the view outlet was greyed out and I couldn't control-drag it.

I figured out that my mistake was in adding a UIViewController in Interface Builder. Instead, I had to add a UIView, and set the Custom Class of the File's Owner to my view controller. Then I could control-drag the view outlet of the File's Owner to my new view UIView and everything worked as it should.

In my case there was no start command in the script section of package.json file. When I created the package.json file with npm init I did not create a start script command. So I went to the package.json file, under scripts I added a new entry:

 "scripts": {
    "start": "node index.js"
  },

Saved it and uploaded to Heroku and it worked

You just write this script. use input element for this.

$("input").val("valuesgoeshere"); 

or by id="fsd" you write this code.

$("input").val(document.getElementById("fsd").innerHTML);

If you`re not using jQuery then please make sure:

var json_upload = "json_name=" + JSON.stringify({name:"John Rambo", time:"2pm"});
var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
xmlhttp.open("POST", "/file.php");
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.send(json_upload);

And for the php receiving end:

 $_POST['json_name'] 

You can loop through the keys:

foo = {one:1, two:2, three:3};
for (key in foo){
    console.log("foo["+ key +"]="+ foo[key]);
}

will output:

foo[one]=1
foo[two]=2
foo[three]=3

I use the following code to create PDF

protected void CreatePDF(Stream stream)
        {
            using (var document = new Document(PageSize.A4, 40, 40, 40, 30))
            {
                var writer = PdfWriter.GetInstance(document, stream);
                writer.PageEvent = new ITextEvents();
                document.Open();

                // instantiate custom tag processor and add to `HtmlPipelineContext`.
                var tagProcessorFactory = Tags.GetHtmlTagProcessorFactory();
                tagProcessorFactory.AddProcessor(
                    new TableProcessor(),
                    new string[] { HTML.Tag.TABLE }
                );

                //Register Fonts.
                XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
                fontProvider.Register(HttpContext.Current.Server.MapPath("~/Content/Fonts/GothamRounded-Medium.ttf"), "Gotham Rounded Medium");
                CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);

                var htmlPipelineContext = new HtmlPipelineContext(cssAppliers);
                htmlPipelineContext.SetTagFactory(tagProcessorFactory);

                var pdfWriterPipeline = new PdfWriterPipeline(document, writer);
                var htmlPipeline = new HtmlPipeline(htmlPipelineContext, pdfWriterPipeline);

                // get an ICssResolver and add the custom CSS
                var cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(true);
                cssResolver.AddCss(CSSSource, "utf-8", true);
                var cssResolverPipeline = new CssResolverPipeline(
                    cssResolver, htmlPipeline
                );

                var worker = new XMLWorker(cssResolverPipeline, true);
                var parser = new XMLParser(worker);
                using (var stringReader = new StringReader(HTMLSource))
                {
                    parser.Parse(stringReader);
                    document.Close();
                    HttpContext.Current.Response.ContentType = "application /pdf";
                    if (base.View)
                        HttpContext.Current.Response.AddHeader("content-disposition", "inline;filename=\"" + OutputFileName + ".pdf\"");
                    else
                        HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=\"" + OutputFileName + ".pdf\"");
                    HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                    HttpContext.Current.Response.WriteFile(OutputPath);
                    HttpContext.Current.Response.End();
                }
            }
        }

In your own (base) class, willSet and didSet are quite reduntant , as you could instead define a calculated property (i.e get- and set- methods) that access a _propertyVariable and does the desired pre- and post- prosessing.

If, however, you override a class where the property is already defined, then the willSet and didSet are useful and not redundant!

BASED ON LARAVEL 5.7 & ABOVE

To get all segments of current URL:

$current_uri = request()->segments();

To get segment posts from http://example.com/users/posts/latest/

NOTE: Segments are an array that starts at index 0. The first element of array starts after the TLD part of the url. So in the above url, segment(0) will be users and segment(1) will be posts.

//get segment 0
$segment_users = request()->segment(0); //returns 'users'
//get segment 1
$segment_posts = request()->segment(1); //returns 'posts'

You may have noted that the segment method only works with the current URL ( url()->current() ). So I designed a method to work with previous URL too by cloning the segment() method:

public function index()
{
    $prev_uri_segments = $this->prev_segments(url()->previous());
}

 /**
 * Get all of the segments for the previous uri.
 *
 * @return array
 */
public function prev_segments($uri)
{
    $segments = explode('/', str_replace(''.url('').'', '', $uri));

    return array_values(array_filter($segments, function ($value) {
        return $value !== '';
    }));
}

Instead of testing for an Array, just convert whatever you get into a one-level Array, so your code only needs to handle the one case.

t = [*something]     # or...
t = Array(something) # or...
def f *x
    ...
end

Ruby has various ways to harmonize an API which can take an object or an Array of objects, so, taking a guess at why you want to know if something is an Array, I have a suggestion.

The splat operator contains lots of magic you can look up, or you can just call Array(something) which will add an Array wrapper if needed. It's similar to [*something] in this one case.

def f x
  p Array(x).inspect
  p [*x].inspect
end
f 1         # => "[1]"
f [1]       # => "[1]"
f [1,2]     # => "[1, 2]"

Or, you could use the splat in the parameter declaration and then .flatten, giving you a different sort of collector. (For that matter, you could call .flatten above, too.)

def f *x
  p x.flatten.inspect
end         # => nil
f 1         # => "[1]"
f 1,2       # => "[1, 2]"
f [1]       # => "[1]"
f [1,2]     # => "[1, 2]"
f [1,2],3,4 # => "[1, 2, 3, 4]"

And, thanks gregschlom, it's sometimes faster to just use Array(x) because when it's already an Array it doesn't need to create a new object.

Here is the way I use to find the external card. Use mount cmd return then parse the vfat part.

String s = "";
try {
Process process = new ProcessBuilder().command("mount")
        .redirectErrorStream(true).start();

process.waitFor();

InputStream is = process.getInputStream();
byte[] buffer = new byte[1024];
while (is.read(buffer) != -1) {
    s = s + new String(buffer);
}
is.close();
} catch (Exception e) {
e.printStackTrace();
}

//????mount??
String[] lines = s.split("\n");
for(int i=0; i<lines.length; i++) {
//???????????vfat??,???????????sd????
if(-1 != lines[i].indexOf(path[0]) && -1 != lines[i].indexOf("vfat")) {
    //??????
    String[] blocks = lines[i].split("\\s");
    for(int j=0; j<blocks.length; j++) {
        //????????vfat??
        if(-1 != blocks[j].indexOf(path[0])) {
            //Test if it is the external sd card.
        }
    }
}
}

To start, Joe Kington's answer provides very good advice using a gui-neutral approach, and you should definitely take his advice (especially about Blitting) and put it into practice. More info on this approach, read the Matplotlib Cookbook

However, the non-GUI-neutral (GUI-biased?) approach is key to speeding up the plotting. In other words, the backend is extremely important to plot speed.

Put these two lines before you import anything else from matplotlib:

import matplotlib
matplotlib.use('GTKAgg') 

Of course, there are various options to use instead of GTKAgg, but according to the cookbook mentioned before, this was the fastest. See the link about backends for more options.

After adding the JDK repo, before Installing you might want to run an update first so the repo can be added run apt update

an then continue with your installation sudo apt install adoptopenjdk-8-hotspot

Ok after having sunk way to much time into this problem this is the way I managed to get the appearance I was hoping for. I'm making it a separate answer so I can get everything in one place.

It's a combination of factors.

Firstly, don't try to get the toolbars to play nice through just themes. It seems to be impossible.

So apply themes explicitly to your Toolbars like in oRRs answer

layout/toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_alignParentTop="true"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:theme="@style/Dark.Overlay"
    app:popupTheme="@style/Dark.Overlay.LightPopup" />

However this is the magic sauce. In order to actually get the background colors I was hoping for you have to override the background attribute in your Toolbar themes

values/styles.xml:

<!-- 
    I expected android:colorBackground to be what I was looking for but
    it seems you have to override android:background
-->
<style name="Dark.Overlay" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:background">?attr/colorPrimary</item>
</style>

<style name="Dark.Overlay.LightPopup" parent="ThemeOverlay.AppCompat.Light">
    <item name="android:background">@color/material_grey_200</item>
</style>

then just include your toolbar layout in your other layouts

<include android:id="@+id/mytoolbar" layout="@layout/toolbar" />

and you're good to go.

Hope this helps someone else so you don't have to spend as much time on this as I have.

(if anyone can figure out how to make this work using just themes, ie not having to apply the themes explicitly in the layout files I'll gladly support their answer instead)

EDIT:

So apparently posting a more complete answer was a downvote magnet so I'll just accept the imcomplete answer above but leave this answer here in case someone actually needs it. Feel free to keep downvoting if it makes you happy though.

You can try :

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" >

Just like you tried before, but caution:

It seems like the X-UA-Compatible tag has to be the first tag in the < head > section

If this conclusion is correct, then I believe it is undocumented in Microsoft’s blogs/msdn (and if it is documented, then it isn’t sticking out well enough from the docs). Ensuring that this was the first meta tag in the forced IE9 to switch to IE8 mode successfully

Just to add on to the topic of for in/for/$.each, I added a jsperf test case for using $.each vs for in: http://jsperf.com/each-vs-for-in/2

Different browsers/versions handle it differently, but it seems $.each and straight out for in are the cheapest options performance-wise.

If you're using for in to iterate through an associative array/object, knowing what you're after and ignoring everything else, use $.each if you use jQuery, or just for in (and then a break; once you've reached what you know should be the last element)

If you're iterating through an array to perform something with each key pair in it, should use the hasOwnProperty method if you DON'T use jQuery, and use $.each if you DO use jQuery.

Always use for(i=0;i<o.length;i++) if you don't need an associative array though... lol chrome performed that 97% faster than a for in or $.each

Just another alternative solution for those who want to pass variables to a script which is sourced using flask, I only managed to get this working by defining the variables outside and then calling the script as follows:

    <script>
    var myfileuri = "/static/my_csv.csv"
    var mytableid = 'mytable';
    </script>
    <script type="text/javascript" src="/static/test123.js"></script>

If I input jinja variables in test123.js it doesn't work and you will get an error.

Even though this is a very old thread, I feel like I need to contribute a simple solution. Any time that you know where in Management Studio a parameter is located that you want to access for any sort of automated script, the easiest way is to run a quick profiler trace on a standalone test system and capture what Management Studio is doing on the backend.

In this instance, assuming you are interested in finding the default data and log locations you can do the following:

SELECT
     SERVERPROPERTY('instancedefaultdatapath') AS [DefaultFile],
     SERVERPROPERTY('instancedefaultlogpath') AS [DefaultLog]

I have crafted an alternative non-jQuery version:

document.cookie.match(/^(.*;)?\s*MyCookie\s*=\s*[^;]+(.*)?$/)

It only tests for cookie existence. A more complicated version can also return cookie value:

value_or_null = (document.cookie.match(/^(?:.*;)?\s*MyCookie\s*=\s*([^;]+)(?:.*)?$/)||[,null])[1]

Put your cookie name in in place of MyCookie.

There are certain common things between lock_guard and unique_lock and certain differences.

But in the context of the question asked, the compiler does not allow using a lock_guard in combination with a condition variable, because when a thread calls wait on a condition variable, the mutex gets unlocked automatically and when other thread/threads notify and the current thread is invoked (comes out of wait), the lock is re-acquired.

This phenomenon is against the principle of lock_guard. lock_guard can be constructed only once and destructed only once.

Hence lock_guard cannot be used in combination with a condition variable, but a unique_lock can be (because unique_lock can be locked and unlocked several times).

android:background="#64B5F6"
You can change the value after '#' according to your own specification or need depending on how you want to use them.
Here is a sample code:

<TextView_x000D_
        android:text="Abir"_x000D_
        android:layout_width="match_parent"_x000D_
        android:layout_height="wrap_content"_x000D_
        android:textSize="24sp"_x000D_
        android:background="#D4E157"  />

Thank you :)

Perhaps the single biggest "benefit" of dynamic typing is the shallower learning curve. There is no type system to learn and no non-trivial syntax for corner cases such as type constraints. That makes dynamic typing accessible to a lot more people and feasible for many people for whom sophisticated static type systems are out of reach. Consequently, dynamic typing has caught on in the contexts of education (e.g. Scheme/Python at MIT) and domain-specific languages for non-programmers (e.g. Mathematica). Dynamic languages have also caught on in niches where they have little or no competition (e.g. Javascript).

The most concise dynamically-typed languages (e.g. Perl, APL, J, K, Mathematica) are domain specific and can be significantly more concise than the most concise general-purpose statically-typed languages (e.g. OCaml) in the niches they were designed for.

The main disadvantages of dynamic typing are:

• Run-time type errors.

• Can be very difficult or even practically impossible to achieve the same level of correctness and requires vastly more testing.

• No compiler-verified documentation.

• Poor performance (usually at run-time but sometimes at compile time instead, e.g. Stalin Scheme) and unpredictable performance due to dependence upon sophisticated optimizations.

Personally, I grew up on dynamic languages but wouldn't touch them with a 40' pole as a professional unless there were no other viable options.

First, have you compiled the class using the command line javac compiler? Second, it seems that your main method has an incorrect signature - it should be taking in an array of String objects, rather than just one:

public static void main(String[] args){

Once you've changed your code to take in an array of String objects, then you need to make sure that you're printing an element of the array, rather than array itself:

System.out.println(args[0])

If you want to print the whole list of command line arguments, you'd need to use a loop, e.g.

for(int i = 0; i < args.length; i++){
    System.out.print(args[i]);
}
System.out.println();

Just multiply the number by 100, round, and divide the resulting number by 100.

You can use the Lambda functions of Java 8 to achieve this without looping

    String string = "1, 2, 3, 4";
    List<Integer> list = Arrays.asList(string.split(",")).stream().map(s -> Integer.parseInt(s.trim())).collect(Collectors.toList());

Use oracle.jdbc.OracleDriver, not oracle.jdbc.driver.OracleDriver. You do not need to register it if the driver jar file is in the "WEB-INF\lib" directory, if you are using Tomcat. Save this as test.jsp and put it in your web directory, and redeploy your web app folder in Tomcat manager:

<%@ page import="java.sql.*" %>

<HTML>
<HEAD>
<TITLE>Simple JSP Oracle Test</TITLE>
</HEAD><BODY>
<%
Connection conn = null;
try {
    Class.forName("oracle.jdbc.OracleDriver");
    conn = DriverManager.getConnection("jdbc:oracle:thin:@XXX.XXX.XXX.XXX:XXXX:dbName", "user", "password");
    Statement stmt = conn.createStatement();
    out.println("Connection established!");
}
catch (Exception ex)
{
    out.println("Exception: " + ex.getMessage() + "");

}
finally
{
    if (conn != null) {
        try {
            conn.close();   
        }
        catch (Exception ignored) {
            // ignore
        }
    }
}

%>

Or, KISS.

DIRS=build build/bins

... 

$(shell mkdir -p $(DIRS))

This will create all the directories after the Makefile is parsed.

In query where you are passing query parameters, typecast parameter to an integer

e.g. in the case of PostgreSQL, it might be

where table_name.column_name_with_integer_type = (:named_parameter_of_character_type)::integer

::integer will convert the parameter value into an integer.

Java 8 introduces the Instant.ofEpochSecond utility method for creating an Instant from a Unix timestamp, this can then be converted into a ZonedDateTime and finally formatted, e.g.:

final DateTimeFormatter formatter = 
    DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

final long unixTime = 1372339860;
final String formattedDtm = Instant.ofEpochSecond(unixTime)
        .atZone(ZoneId.of("GMT-4"))
        .format(formatter);

System.out.println(formattedDtm);   // => '2013-06-27 09:31:00'

I thought this might be useful for people who are using Java 8.

This is a real, real life scenario, because it actually happened yesterday:

• Z-index in jQuery dialog. Autosuggest list not displayed properly

Alternatives to not using !important in my answer included:

• Hunting down in JavaScript/CSS where a certain elusive property was being applied.
• Adding the property with JavaScript, which is little better than using !important.

So, a benefit of !important is that it sometimes saves time. If you use it very sparingly like this, it can be a useful tool.

If you're using it just because you don't understand how specificity works, you're doing it wrong.

Another use for !important is when you're writing some kind of external widget type thing, and you want to be sure that your styles will be the ones applied, see:

• Appended control's CSS

Your syntax is wrong.

You need to call attr with two parameters, like this:

$('.salesperson', newOption).attr('defaultSelected', "selected");

Your current code assigns the value "selected" to the variable defaultSelected, then passes that value to the attr function, which will then return the value of the selected attribute.

You can cast this value to a Boolean in a very simple manner: by comparing it with integer value 1, like this:

boolean multipleContacts = new Integer(1).equals(jsonObject.get("MultipleContacts"))

If it is a String, you could do this:

boolean multipleContacts = "1".equals(jsonObject.get("MultipleContacts"))

You can also check for socket output stream error while writing to client socket.

out.println(output);
if(out.checkError())
{
    throw new Exception("Error transmitting data.");
}

It's not a good idea to include any environment-dependent component or setting in your repos as one of the key aspects of using a repo, is perhaps, sharing it with other developers. Here is how I would setup my development environment on a Windows PC (say, Win10).

1. Open Pycharm and on the first page, choose to check out the project from your Source Control System (in my case, I am using github)

2. In Pycharm, navigate to settings and choose "Project Interpreter" and choose the option to add a new virtual environment , you can call it "venv".

3. Choose the base python interpreter which is located at C:\Users{user}\AppData\Local\Programs\Python\Python36 (make sure you choose the appropriate version of Python based on what you have installed)

4. Note that Pycharm will create the new virtual environment and copy python binaries and required libraries under your venv folder inside your project folder.

5. Let Pycharm complete its scanning as it needs to rebuild/refresh your project skeleton

6. exclude venv folder from your git interactions (add venv\ to .gitignore file in your project folder)

Bonus: If you want people to easily (well, almost easily) install all the libraries your software needs, you can use

pip freeze > requirements.txt

and put the instruction on your git so people can use the following command to download all required libraries at once.

pip install -r requirements.txt 

For AWS SDK 2+

String key = "filePath";
String bucketName = "bucketName";
PutObjectResponse response = s3Client
            .putObject(PutObjectRequest.builder().bucket(bucketName ).key(key).build(), RequestBody.fromFile(file));
 GetUrlRequest request = GetUrlRequest.builder().bucket(bucketName ).key(key).build();
 String url = s3Client.utilities().getUrl(request).toExternalForm();

I'm not sure if I understand your question properly, but it shouldn't matter if this div is a child of some other div. You can simply get text from all divs with class bgHeaderH2 by using following code:

$(".bgHeaderH2").text();

var x = document.getElementById("myTable").rows.length;

useEffect has its own state/lifecycle, it will not update until you pass a function in parameters or effect destroyed.

object and array spread or rest will not work inside useEffect.

React.useEffect(() => {
    console.log("effect");
    (async () => {
        try {
            let result = await fetch("/query/countries");

            setData({
                countries: res,
                projects: res1,
                regions: res11
            });
        } catch {}
    })(data)

# or use this
useEffect(() => {
    (async () => {

            await Promise.all([

                fetch("/query/projects").then((response) => response.json()),
                fetch("/query/regions").then((response) => response.json())
            ]).then(([country, project, region]) => {
                // console.log(country, project, region);
                setData({

This function creates a temporary form, then send data using jQuery :

function postToIframe(data,url,target){
    $('body').append('<form action="'+url+'" method="post" target="'+target+'" id="postToIframe"></form>');
    $.each(data,function(n,v){
        $('#postToIframe').append('<input type="hidden" name="'+n+'" value="'+v+'" />');
    });
    $('#postToIframe').submit().remove();
}

target is the 'name' attr of the target iFrame, and data is a JS object :

data={last_name:'Smith',first_name:'John'}

If you need to open the DevTools press ctrl-shift-i.

If the DevTools window is already opened you can use the ctrl-shift-d shortcut; it switches the window into a detached mode.

For example in my case the electron application window (Chrome) is really small.

It's not possible to use any other suggestions except the ctrl-shift-d shortcut

Probably not what you want to hear, but a "feeds" table would be a great middleman for this sort of transaction, giving you a denormalized way of pivoting to all these data with a polymorphic relationship.

You could build it like this:

<?php

Schema::create('feeds', function($table) {
    $table->increments('id');
    $table->timestamps();
    $table->unsignedInteger('user_id');
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->morphs('target'); 
});

Build the feed model like so:

<?php

class Feed extends Eloquent
{
    protected $fillable = ['user_id', 'target_type', 'target_id'];

    public function user()
    {
        return $this->belongsTo('User');
    }

    public function target()
    {
        return $this->morphTo();
    }
}

Then keep it up to date with something like:

<?php

Vote::created(function(Vote $vote) {
    $target_type = 'Vote';
    $target_id   = $vote->id;
    $user_id     = $vote->user_id;

    Feed::create(compact('target_type', 'target_id', 'user_id'));
});

You could make the above much more generic/robust—this is just for demonstration purposes.

At this point, your feed items are really easy to retrieve all at once:

<?php

Feed::whereIn('user_id', $my_friend_ids)
    ->with('user', 'target')
    ->orderBy('created_at', 'desc')
    ->get();

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

@Rogue Coder

This is great!

You could simply use the modulo operation (MOD or % in mysql) to make your code simple at the end:

Instead of:

AND (
    ( CASE ( 1299132000 - EM1.`meta_value` )
        WHEN 0
          THEN 1
        ELSE ( 1299132000 - EM1.`meta_value` )
      END
    ) / EM2.`meta_value`
) = 1

Do:

$current_timestamp = 1299132000 ;

AND ( ('$current_timestamp' - EM1.`meta_value` ) MOD EM2.`meta_value`) = 1")

To take this further, one could include events that do not recur for ever.

Something like "repeat_interval_1_end" to denote the date of the last "repeat_interval_1" could be added. This however, makes the query more complicated and I can't really figure out how to do this ...

Maybe someone could help!

The thing is that, when you call a function you should not write the type of the function, that means you should call the funnction just like

initializeJSP(Experiment);

Quit (force quit) all instances of chrome. Otherwise the below command will not work.

open -a "Google Chrome" --args --allow-file-access-from-files

Executing this command in terminal will open Chrome regardless of where it is installed.

There is a simple solution I learned with "We <3 Swift" if you can't either import Foundation, use round() and/or does not want a String:

var number = 31.726354765
var intNumber = Int(number * 1000.0)
var roundedNumber = Double(intNumber) / 1000.0

result: 31.726

Unfortunately, there is not a direct way to do this with a single formula. However, there is a fairly simple workaround that exists.

On the Excel Ribbon, go to "Formulas" and click on "Name Manager". Select "New" and then enter "CellColor" as the "Name". Jump down to the "Refers to" part and enter the following:

=GET.CELL(63,OFFSET(INDIRECT("RC",FALSE),1,1))

Hit OK then close the "Name Manager" window.

Now, in cell A1 enter the following:

=IF(CellColor=3,"FQS",IF(CellColor=6,"SM",""))

This will return FQS for red and SM for yellow. For any other color the cell will remain blank.

***If the value in A1 doesn't update, hit 'F9' on your keyboard to force Excel to update the calculations at any point (or if the color in B2 ever changes).

Below is a reference for a list of cell fill colors (there are 56 available) if you ever want to expand things: http://www.smixe.com/excel-color-pallette.html

Cheers.

::Edit::

The formula used in Name Manager can be further simplified if it helps your understanding of how it works (the version that I included above is a lot more flexible and is easier to use in checking multiple cell references when copied around as it uses its own cell address as a reference point instead of specifically targeting cell B2).

Either way, if you'd like to simplify things, you can use this formula in Name Manager instead:

=GET.CELL(63,Sheet1!B2)

This worked for me.

header = ['row1', 'row2', 'row3']
some_list = [1, 2, 3]
with open('test.csv', 'wt', newline ='') as file:
    writer = csv.writer(file, delimiter=',')
    writer.writerow(i for i in header)
    for j in some_list:
        writer.writerow(j)

You can pass the inline handler the this keyword, obtaining the element which fired the event.

like,

onclick="confirmSubmit(this);"

You might be using C:/[your-php-directory]/php.exe in Handler mapping of IIS just change it C:/[your-php-directory]/php-cgi.exe.

For me this approach works:

The dialog may be closed by clicking the X on the dialog or by clicking 'Bewaren'. I'm adding an (arbitrary) id because I need to be sure every bit of html added to the dom is removed afterwards.

$('<div id="dossier_edit_form_tmp_id">').html(data.form)
.data('dossier_id',dossier_id)
.dialog({
        title: 'Opdracht wijzigen',
        show: 'clip',
        hide: 'clip',
        minWidth: 520,
        width: 520,
        modal: true,
        buttons: { 'Bewaren': dossier_edit_form_opslaan },
        close: function(event, ui){ 
                                  $(this).dialog('destroy'); 
                                  $('#dossier_edit_form_tmp_id').remove();
               }
});

The below code stores the return value in to the variable retVal and then MsgBox can be used to display the value:

Dim retVal As Integer
retVal = test()
Msgbox retVal

By default maven does not include any files from "src/main/java".

You have two possible way to that.

1. put all your resource files (different than java files) to "src/main/resources" - this is highly recommended

2. Add to your pom (resource plugin):

?

 <resources>
       <resource>
           <directory>src/main/resources</directory>
        </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
  </resources>

Here is a different approach using mix-blend-mode: difference, that will actually invert whatever the background is, not just a single colour:

div {_x000D_
  background-image: linear-gradient(to right, red, yellow, green, cyan, blue, violet);_x000D_
}_x000D_
p {_x000D_
  color: white;_x000D_
  mix-blend-mode: difference;_x000D_
}

<div>_x000D_
  <p>Lorem ipsum dolor sit amet, consectetur adipiscit elit, sed do</p>_x000D_
</div>

Big difference between an image and an iframe is the fact that an image keeps its aspect-ratio. You could combine an image and an iframe with will result in a responsive iframe. Hope this answerers your question.

Check this link for example : http://jsfiddle.net/Masau/7WRHM/

HTML:

<div class="wrapper">
    <div class="h_iframe">
        <!-- a transparent image is preferable -->
        <img class="ratio" src="http://placehold.it/16x9"/>
        <iframe src="http://www.youtube.com/embed/WsFWhL4Y84Y" frameborder="0" allowfullscreen></iframe>
    </div>
    <p>Please scale the "result" window to notice the effect.</p>
</div>

CSS:

html,body        {height:100%;}
.wrapper         {width:80%;height:100%;margin:0 auto;background:#CCC}
.h_iframe        {position:relative;}
.h_iframe .ratio {display:block;width:100%;height:auto;}
.h_iframe iframe {position:absolute;top:0;left:0;width:100%; height:100%;}

note: This only works with a fixed aspect-ratio.

Here is an alternative. Create a generic exception that takes a status code and a message. Then create an exception handler. Use the exception handler to retrieve the information out of the exception and return to the caller of the service.

http://javaninja.net/2016/06/throwing-exceptions-messages-spring-mvc-controller/

public class ResourceException extends RuntimeException {

    private HttpStatus httpStatus = HttpStatus.INTERNAL_SERVER_ERROR;

    public HttpStatus getHttpStatus() {
        return httpStatus;
    }

    /**
     * Constructs a new runtime exception with the specified detail message.
     * The cause is not initialized, and may subsequently be initialized by a
     * call to {@link #initCause}.
     * @param message the detail message. The detail message is saved for later retrieval by the {@link #getMessage()}
     *                method.
     */
    public ResourceException(HttpStatus httpStatus, String message) {
        super(message);
        this.httpStatus = httpStatus;
    }
}

Then use an exception handler to retrieve the information and return it to the service caller.

@ControllerAdvice
public class ExceptionHandlerAdvice { 

    @ExceptionHandler(ResourceException.class)
    public ResponseEntity handleException(ResourceException e) {
        // log exception 
        return ResponseEntity.status(e.getHttpStatus()).body(e.getMessage());
    }         
} 

Then create an exception when you need to.

throw new ResourceException(HttpStatus.NOT_FOUND, "We were unable to find the specified resource.");

i believe the following code will only run after form1 is closed

 while (true)
    {
        if (form1.Visible == false)
            form2.Show();
    }

Why not start your form2 from form1 instead?

Form2 form2 = new Form2();
 private void button1_Click_1(object sender, EventArgs e)
    {
        if (richTextBox1.Text != null)
        {
            form1.Visible=false;
            form2.Show();

        }
        else MessageBox.Show("Insert Attributes First !");

    }

Here's an efficient option that doesn't use the clipboard.

Sub transposeAndPasteRow(rowToCopy As Range, pasteTarget As Range)
    pasteTarget.Resize(rowToCopy.Columns.Count) = Application.WorksheetFunction.Transpose(rowToCopy.Value)
End Sub

Use it like this.

Sub test()
    Call transposeAndPasteRow(Worksheets("Sheet1").Range("A1:A5"), Worksheets("Sheet2").Range("A1"))
End Sub
