Take the number 123.456789

• As an integer, this number would be 123
• As a fixed point (2), this number would be 123.46 (Assuming you rounded it up)
• As a floating point, this number would be 123.456789

Floating point lets you represent most every number with a great deal of precision. Fixed is less precise, but simpler for the computer..

ast.literal_eval (located in ast.py) parses the tree with ast.parse first, then it evaluates the code with quite an ugly recursive function, interpreting the parse tree elements and replacing them with their literal equivalents. Unfortunately the code is not at all expandable, so to add Decimal to the code you need to copy all the code and start over.

For a slightly easier approach, you can use ast.parse module to parse the expression, and then the ast.NodeVisitor or ast.NodeTransformer to ensure that there is no unwanted syntax or unwanted variable accesses. Then compile with compile and eval to get the result.

The code is a bit different from literal_eval in that this code actually uses eval, but in my opinion is simpler to understand and one does not need to dig too deep into AST trees. It specifically only allows some syntax, explicitly forbidding for example lambdas, attribute accesses (foo.__dict__ is very evil), or accesses to any names that are not deemed safe. It parses your expression fine, and as an extra I also added Num (float and integer), list and dictionary literals.

Also, works the same on 2.7 and 3.3

import ast
import decimal

source = "(Decimal('11.66985'), Decimal('1e-8'),"\
    "(1,), (1,2,3), 1.2, [1,2,3], {1:2})"

tree = ast.parse(source, mode='eval')

# using the NodeTransformer, you can also modify the nodes in the tree,
# however in this example NodeVisitor could do as we are raising exceptions
# only.
class Transformer(ast.NodeTransformer):
    ALLOWED_NAMES = set(['Decimal', 'None', 'False', 'True'])
    ALLOWED_NODE_TYPES = set([
        'Expression', # a top node for an expression
        'Tuple',      # makes a tuple
        'Call',       # a function call (hint, Decimal())
        'Name',       # an identifier...
        'Load',       # loads a value of a variable with given identifier
        'Str',        # a string literal

        'Num',        # allow numbers too
        'List',       # and list literals
        'Dict',       # and dicts...
    ])

    def visit_Name(self, node):
        if not node.id in self.ALLOWED_NAMES:
            raise RuntimeError("Name access to %s is not allowed" % node.id)

        # traverse to child nodes
        return self.generic_visit(node)

    def generic_visit(self, node):
        nodetype = type(node).__name__
        if nodetype not in self.ALLOWED_NODE_TYPES:
            raise RuntimeError("Invalid expression: %s not allowed" % nodetype)

        return ast.NodeTransformer.generic_visit(self, node)


transformer = Transformer()

# raises RuntimeError on invalid code
transformer.visit(tree)

# compile the ast into a code object
clause = compile(tree, '<AST>', 'eval')

# make the globals contain only the Decimal class,
# and eval the compiled object
result = eval(clause, dict(Decimal=decimal.Decimal))

print(result)

#include<iostream>
#include<conio.h>
#include<stdlib.h>
using namespace std;
void displayBinary(int n)
{
       char bistr[1000];
       itoa(n,bistr,2);       //2 means binary u can convert n upto base 36
       printf("%s",bistr);

}

int main()
{
    int n;
    cin>>n;
    displayBinary(n);
    getch();
    return 0;
}

Here is the true way to get binary representation of a number:

unsigned int i = *(unsigned int*) &x;

You can just write

System.Diagnostics.Process.Start("http://google.com");

EDIT: The WebBrowser control is an embedded copy of IE.
Therefore, any links inside of it will open in IE.

To change this behavior, you can handle the Navigating event.

Let's start by describing DOM elements' event handling.

DOM node event handling

First of all you wouldn't want to work with DOM node directly. Instead you probably would want to utilize Ext.Element interface. For the purpose of assigning event handlers, Element.addListener and Element.on (these are equivalent) were created. So, for example, if we have html:

<div id="test_node"></div>

and we want add click event handler.
Let's retrieve Element:

var el = Ext.get('test_node');

Now let's check docs for click event. It's handler may have three parameters:

click( Ext.EventObject e, HTMLElement t, Object eOpts )

Knowing all this stuff we can assign handler:

//       event name      event handler
el.on(    'click'        , function(e, t, eOpts){
  // handling event here
});

Widgets event handling

Widgets event handling is pretty much similar to DOM nodes event handling.

First of all, widgets event handling is realized by utilizing Ext.util.Observable mixin. In order to handle events properly your widget must containg Ext.util.Observable as a mixin. All built-in widgets (like Panel, Form, Tree, Grid, ...) has Ext.util.Observable as a mixin by default.

For widgets there are two ways of assigning handlers. The first one - is to use on method (or addListener). Let's for example create Button widget and assign click event to it. First of all you should check event's docs for handler's arguments:

click( Ext.button.Button this, Event e, Object eOpts )

Now let's use on:

var myButton = Ext.create('Ext.button.Button', {
  text: 'Test button'
});
myButton.on('click', function(btn, e, eOpts) {
  // event handling here
  console.log(btn, e, eOpts);
});

The second way is to use widget's listeners config:

var myButton = Ext.create('Ext.button.Button', {
  text: 'Test button',
  listeners : {
    click: function(btn, e, eOpts) {
      // event handling here
      console.log(btn, e, eOpts);
    }
  }
});

Notice that Button widget is a special kind of widgets. Click event can be assigned to this widget by using handler config:

var myButton = Ext.create('Ext.button.Button', {
  text: 'Test button',
  handler : function(btn, e, eOpts) {
    // event handling here
    console.log(btn, e, eOpts);
  }
});

Custom events firing

First of all you need to register an event using addEvents method:

myButton.addEvents('myspecialevent1', 'myspecialevent2', 'myspecialevent3', /* ... */);

Using the addEvents method is optional. As comments to this method say there is no need to use this method but it provides place for events documentation.

To fire your event use fireEvent method:

myButton.fireEvent('myspecialevent1', arg1, arg2, arg3, /* ... */);

arg1, arg2, arg3, /* ... */ will be passed into handler. Now we can handle your event:

myButton.on('myspecialevent1', function(arg1, arg2, arg3, /* ... */) {
  // event handling here
  console.log(arg1, arg2, arg3, /* ... */);
});

It's worth mentioning that the best place for inserting addEvents method call is widget's initComponent method when you are defining new widget:

Ext.define('MyCustomButton', {
  extend: 'Ext.button.Button',
  // ... other configs,
  initComponent: function(){
    this.addEvents('myspecialevent1', 'myspecialevent2', 'myspecialevent3', /* ... */);
    // ...
    this.callParent(arguments);
  }
});
var myButton = Ext.create('MyCustomButton', { /* configs */ });

Preventing event bubbling

To prevent bubbling you can return false or use Ext.EventObject.preventDefault(). In order to prevent browser's default action use Ext.EventObject.stopPropagation().

For example let's assign click event handler to our button. And if not left button was clicked prevent default browser action:

myButton.on('click', function(btn, e){
  if (e.button !== 0)
    e.preventDefault();
});

You can generate pairs like this:

{(x, x + 2) for x in r if x + 2 in r}

Then all that is left to do is to get a condition to make them prime, which you have already done in the first example.

A different way of doing it: (Although slower for large sets of primes)

{(x, y) for x in r for y in r if x + 2 == y}

The <span> tag will need to be set to display:block as it is an inline element and will ignore width.

so:

<style type="text/css"> span { width: 50px; display: block; } </style>

and then:

<li><span>&nbsp;</span>something</li>
<li><span>AND</span>something else</li>

[CREATE PROCEDURE [rat].[GetYear]

You can override the onDraw method of your view and draw the circle.

protected void onDraw(Canvas canvas) {
 super.onDraw(canvas);

 canvas.drawCircle(x, y, radius, paint);

}

For a better reference on drawing custom views check out the official Android documentation.

http://developer.android.com/training/custom-views/custom-drawing.html

For a simple plain JavaScript implementation:

window.onbeforeunload = function () {_x000D_
  window.scrollTo(0, 0);_x000D_
}

You have three alternatives:

1. Use iFrame-resizer

This is a simple library for keeping iFrames sized to their content. It uses the PostMessage and MutationObserver APIs, with fall backs for IE8-10. It also has options for the content page to request the containing iFrame is a certain size and can also close the iFrame when your done with it.

https://github.com/davidjbradshaw/iframe-resizer

2. Use Easy XDM (PostMessage + Flash combo)

Easy XDM uses a collection of tricks for enabling cross-domain communication between different windows in a number of browsers, and there are examples for using it for iframe resizing:

http://easyxdm.net/wp/2010/03/17/resize-iframe-based-on-content/

http://kinsey.no/blog/index.php/2010/02/19/resizing-iframes-using-easyxdm/

Easy XDM works by using PostMessage on modern browsers and a Flash based solution as fallback for older browsers.

See also this thread on Stackoverflow (there are also others, this is a commonly asked question). Also, Facebook would seem to use a similar approach.

3. Communicate via a server

Another option would be to send the iframe height to your server and then poll from that server from the parent web page with JSONP (or use a long poll if possible).

In sql 2012 (and maybe as far back as 2005), you should do this:

EXEC AddBrand @BrandName = 'Gucci', @CategoryId = 23

If your variable data1$c is a factor, it's more efficient to change the labels of the factor levels than to create a new vector of characters:

levels(data1$c) <- sub("_", "-", levels(data1$c))


            a b   c
1  0.73945260 a A-B
2  0.75998815 b A-B
3  0.19576725 c A-B
4  0.85932140 d A-B
5  0.80717115 e A-C
6  0.09101492 f A-C
7  0.10183586 g A-C
8  0.97742424 h A-C
9  0.21364521 i A-C
10 0.02389782 j A-C

An other approach is to use a Virtual JDBC Driver that uses a three-tier architecture: your JDBC code is sent through HTTP to a remote Servlet that filters the JDBC code (configuration & security) before passing it to the MySql JDBC Driver. The result is sent you back through HTTP. There are some free software that use this technique. Just Google "Android JDBC Driver over HTTP".

If you would like to execute the parent controller's parentmethod function inside a child controller, call it:

$scope.$parent.parentmethod();

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

You can use boost::lexical_cast, as suggested, but if you have any prior knowledge about the strings (i.e. that if a string contains an integer literal it won't have any leading space, or that integers are never written with exponents), then rolling your own function should be both more efficient, and not particularly difficult.

One of my SQL jobs had the same issue. It involved uploadaing data from one server to another. The error occurred because I was using sql Server Agent Service Account. I created a Credential using a UserId (that uses Window authentication) common to all servers. Then created a Proxy using this credential. Used the proxy in sql server job and it is running fine.

u should add a theme to ur all activities (u should add theme for all application in ur <application> in ur manifest) but if u have set different theme to ur activity u can use :

 android:theme="@style/Theme.AppCompat"

or each kind of AppCompat theme!

First, you want to use

model <- lm(Total ~ Coupon, data=df)

not model <-lm(df$Total ~ df$Coupon, data=df).

Second, by saying lm(Total ~ Coupon), you are fitting a model that uses Total as the response variable, with Coupon as the predictor. That is, your model is of the form Total = a + b*Coupon, with a and b the coefficients to be estimated. Note that the response goes on the left side of the ~, and the predictor(s) on the right.

Because of this, when you ask R to give you predicted values for the model, you have to provide a set of new predictor values, ie new values of Coupon, not Total.

Third, judging by your specification of newdata, it looks like you're actually after a model to fit Coupon as a function of Total, not the other way around. To do this:

model <- lm(Coupon ~ Total, data=df)
new.df <- data.frame(Total=c(79037022, 83100656, 104299800))
predict(model, new.df)

Using jQuery it's quite trivial. v2.0 uses the table class on all tables.

$('.table > tbody > tr').click(function() {
    // row was clicked
});

Chrome and Safari has a restriction on using ajax with local resources. That's why it's throwing an error like

Origin null is not allowed by Access-Control-Allow-Origin.

Solution: Use firefox or upload your data to a temporary server. If you still want to use Chrome, start it with the below option;

--allow-file-access-from-files

More info how to add the above parameter to your Chrome: Right click the Chrome icon on your task bar, right click the Google Chrome on the pop-up window and click properties and add the above parameter inside the Target textbox under Shortcut tab. It will like as below;

C:\Users\XXX_USER\AppData\Local\Google\Chrome\Application\chrome.exe --allow-file-access-from-files

Hope this will help!

add:

overflow-y: scroll

All the above works, and here is another way if you just want to number of days/time back rather a entering date

select * from *table_name* where *datetime_column* BETWEEN DATE_SUB(NOW(), INTERVAL 30 DAY)  AND NOW() 

grep -Fxvf file1 file2

What the flags mean:

-F, --fixed-strings
              Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.    
-x, --line-regexp
              Select only those matches that exactly match the whole line.
-v, --invert-match
              Invert the sense of matching, to select non-matching lines.
-f FILE, --file=FILE
              Obtain patterns from FILE, one per line.  The empty file contains zero patterns, and therefore matches nothing.

HttpContext.Current.Request.Url.Host is returning the correct values. If you run it on www.somedomainname.com it will give you www.somedomainname.com. If you want to get the 5858 as well you need to use

HttpContext.Current.Request.Url.Port 

To solve the problem I use ${string_prompt} variable. It shows a input dialog when application runs. I can set the date/time manually at that dialog.

1. Move cursor at the end of file path.

2. Click variables and select string_prompt

3. Select Apply and Run

I've had the same problem.
The reason was, that my local branch had somehow lost the tracking to the remote counterpart.

After

git branch branch_name --set-upstream-to=origin/branch_name
git pull

and resolving the merging conflicts, I was able to push.

$this->db->like()

This method enables you to generate LIKE clauses, useful for doing searches.

$this->db->like('title', 'match');

Produces: WHERE title LIKE '%match%'

If you want to control where the wildcard (%) is placed, you can use an optional third argument. Your options are ‘before’, ‘after’, ‘none’ and ‘both’ (which is the default).

$this->db->like('title', 'match', 'before');

Produces: WHERE title LIKE '%match'

$this->db->like('title', 'match', 'after');

Produces: WHERE title LIKE 'match%'

$this->db->like('title', 'match', 'none');

Produces: WHERE title LIKE 'match'

$this->db->like('title', 'match', 'both');

Produces: WHERE title LIKE '%match%'

This should be done in the dataset. You could do this

Select CAST(CAST(YourDateTime as date) AS Varchar(11)) as DateColumnName

In SSRS Layout, just do this =Fields!DateColumnName.Value

A typical situation with multiple cascasing paths will be this: A master table with two details, let's say "Master" and "Detail1" and "Detail2". Both details are cascade delete. So far no problems. But what if both details have a one-to-many-relation with some other table (say "SomeOtherTable"). SomeOtherTable has a Detail1ID-column AND a Detail2ID-column.

Master { ID, masterfields }

Detail1 { ID, MasterID, detail1fields }

Detail2 { ID, MasterID, detail2fields }

SomeOtherTable {ID, Detail1ID, Detail2ID, someothertablefields }

In other words: some of the records in SomeOtherTable are linked with Detail1-records and some of the records in SomeOtherTable are linked with Detail2 records. Even if it is guaranteed that SomeOtherTable-records never belong to both Details, it is now impossible to make SomeOhterTable's records cascade delete for both details, because there are multiple cascading paths from Master to SomeOtherTable (one via Detail1 and one via Detail2). Now you may already have understood this. Here is a possible solution:

Master { ID, masterfields }

DetailMain { ID, MasterID }

Detail1 { DetailMainID, detail1fields }

Detail2 { DetailMainID, detail2fields }

SomeOtherTable {ID, DetailMainID, someothertablefields }

All ID fields are key-fields and auto-increment. The crux lies in the DetailMainId fields of the Detail tables. These fields are both key and referential contraint. It is now possible to cascade delete everything by only deleting master-records. The downside is that for each detail1-record AND for each detail2 record, there must also be a DetailMain-record (which is actually created first to get the correct and unique id).

It depends on the encoding of your string (ASCII, UTF-8, ...).

For example:

byte[] b1 = System.Text.Encoding.UTF8.GetBytes (myString);
byte[] b2 = System.Text.Encoding.ASCII.GetBytes (myString);

A small sample why encoding matters:

string pi = "\u03a0";
byte[] ascii = System.Text.Encoding.ASCII.GetBytes (pi);
byte[] utf8 = System.Text.Encoding.UTF8.GetBytes (pi);

Console.WriteLine (ascii.Length); //Will print 1
Console.WriteLine (utf8.Length); //Will print 2
Console.WriteLine (System.Text.Encoding.ASCII.GetString (ascii)); //Will print '?'

ASCII simply isn't equipped to deal with special characters.

Internally, the .NET framework uses UTF-16 to represent strings, so if you simply want to get the exact bytes that .NET uses, use System.Text.Encoding.Unicode.GetBytes (...).

See Character Encoding in the .NET Framework (MSDN) for more information.

I've created an example to show how to. Updated state definition would be:

  $stateProvider
    .state('home', {
      url: '/:foo?bar',
      views: {
        '': {
          templateUrl: 'tpl.home.html',
          controller: 'MainRootCtrl'

        },
        ...
      }

And this would be the controller:

.controller('MainRootCtrl', function($scope, $state, $stateParams) {
    //..
    var foo = $stateParams.foo; //getting fooVal
    var bar = $stateParams.bar; //getting barVal
    //..
    $scope.state = $state.current
    $scope.params = $stateParams; 
})

What we can see is that the state home now has url defined as:

url: '/:foo?bar',

which means, that the params in url are expected as

/fooVal?bar=barValue

These two links will correctly pass arguments into the controller:

<a ui-sref="home({foo: 'fooVal1', bar: 'barVal1'})">
<a ui-sref="home({foo: 'fooVal2', bar: 'barVal2'})">

Also, the controller does consume $stateParams instead of $stateParam.

Link to doc:

• URL Parameters

You can check it here

params : {}

There is also new, more granular setting params : {}. As we've already seen, we can declare parameters as part of url. But with params : {} configuration - we can extend this definition or even introduce paramters which are not part of the url:

.state('other', {
    url: '/other/:foo?bar',
    params: { 
        // here we define default value for foo
        // we also set squash to false, to force injecting
        // even the default value into url
        foo: {
          value: 'defaultValue',
          squash: false,
        },
        // this parameter is now array
        // we can pass more items, and expect them as []
        bar : { 
          array : true,
        },
        // this param is not part of url
        // it could be passed with $state.go or ui-sref 
        hiddenParam: 'YES',
      },
    ...

Settings available for params are described in the documentation of the $stateProvider

Below is just an extract

• value - {object|function=}: specifies the default value for this parameter. This implicitly sets this parameter as optional...
• array - {boolean=}: (default: false) If true, the param value will be treated as an array of values.
• squash - {bool|string=}: squash configures how a default parameter value is represented in the URL when the current parameter value is the same as the default value.

We can call these params this way:

// hidden param cannot be passed via url
<a href="#/other/fooVal?bar=1&amp;bar=2">
// default foo is skipped
<a ui-sref="other({bar: [4,5]})">

     Select Distinct[A] FROM MyDatabase

The simplest is to use replace:

"foo bar\t".replace(" ", "").replace("\t", "")

Alternatively, use a regular expression:

import re
re.sub(r"\s", "", "foo bar\t")

Actually, as long as the parent element is positioned, you can set the child's height to 100%. Namely, in case you don't want the parent to be absolutely positioned. Let me explain further:

<style>
    #outer2 {
        padding-left: 23px;
        position: relative; 
        height:auto; 
        width:200px; 
        border: 1px solid red; 
    }
    #inner2 {
        left:0;
        position:absolute; 
        height:100%; 
        width:20px; 
        border: 1px solid black; 
    }
</style>

<div id='outer2'>
    <div id='inner2'>
    </div>
</div>

rand() % (max_number + 1 - minimum_number) + minimum_number

So, for 0-65:

rand() % (65 + 1 - 0) + 0

(obviously you can leave the 0 off, but it's there for completeness).

Note that this will bias the randomness slightly, but probably not anything to be concerned about if you're not doing something particularly sensitive.

Another possible cause for this error message is if the HTTP Method is blocked by the server or load balancer.

It seems to be standard security practice to block unused HTTP Methods. We ran into this because HEAD was being blocked by the load balancer (but, oddly, not all of the load balanced servers, which caused it to fail only some of the time). I was able to test that the request itself worked fine by temporarily changing it to use the GET method.

The error code on iOS was: Error requesting App Code: Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

,@text2 varchar(50)='world'

set @statement = '

exec sp_executesql @statement;

this is same as below :

select @text1 + ' beautifull ' + @text2

Regular Expressions

• Basis of lexical analysis
• Represent regular languages

Context Free Grammars

• Basis of parsing
• Represent language constructs

This is useful in contexts where the encoding is not told per HTTP header or other meta data, e.g. the local file system.

Imagine the following stylesheet:

[rel="external"]::after
{
    content: ' ?';
}

If a reader saves the file to a hard drive and you omit the @charset rule, most browsers will read it in the OS’ locale encoding, e.g. Windows-1252, and insert ↗ instead of an arrow.

Unfortunately, you cannot rely on this mechanism as the support is rather … rare. And remember that on the net an HTTP header will always override the @charset rule.

The correct rules to determine the character set of a stylesheet are in order of priority:

1. HTTP Charset header.
2. Byte Order Mark.
3. The first @charset rule.
4. UTF-8.

The last rule is the weakest, it will fail in some browsers.
The charset attribute in <link rel='stylesheet' charset='utf-8'> is obsolete in HTML 5.
Watch out for conflict between the different declarations. They are not easy to debug.

Recommended reading

• Russ Rolfe: Declaring character encodings in CSS
• IANA: Official names for character sets – other names are not allowed; use the preferred name for @charset if more than one name is registered for the same encoding.
• MDN: @charset. There is a support table. I do not trust this. :)
• Test case from the CSS WG.

Many questions get answers if we use .Net Reflector to see the actual code of SqlConnection :) true and sspi are the same:

internal class DbConnectionOptions

...

internal bool ConvertValueToIntegratedSecurityInternal(string stringValue)
{
    if ((CompareInsensitiveInvariant(stringValue, "sspi") || CompareInsensitiveInvariant(stringValue, "true")) || CompareInsensitiveInvariant(stringValue, "yes"))
    {
        return true;
    }
}

...

EDIT 20.02.2018 Now in .Net Core we can see its open source on github! Search for ConvertValueToIntegratedSecurityInternal method:

https://github.com/dotnet/corefx/blob/fdbb160aeb0fad168b3603dbdd971d568151a0c8/src/System.Data.SqlClient/src/System/Data/Common/DbConnectionOptions.cs

For IE 7 & 8 (and other browsers without CSS3 support not including IE6) you can use the following to get the 2nd and 3rd children:

2nd Child:

td:first-child + td

3rd Child:

td:first-child + td + td

Then simply add another + td for each additional child you wish to select.

If you want to support IE6 that can be done too! You simply need to use a little javascript (jQuery in this example):

$(function() {
    $('td:first-child').addClass("firstChild");
    $(".table-class tr").each(function() {
        $(this).find('td:eq(1)').addClass("secondChild");
        $(this).find('td:eq(2)').addClass("thirdChild");
    });
});

Then in your css you simply use those class selectors to make whatever changes you like:

table td.firstChild { /*stuff here*/ }
table td.secondChild { /*stuff to apply to second td in each row*/ }

If you can update your connector to a version, which supports the new authentication plugin of MySQL 8, then do that. If that is not an option for some reason, change the default authentication method of your database user to native.

Use Layout inflater method in your button click. it will change your current .xml to targeted .xml file. Google for layout inflater code.

If you want to be able to show / hide singular divs and / or groups of divs with less code, just apply several classes to them, to insert them into groups if needed.

Example :

.group1 {}
.group2 {}
.group3 {}

<div class="group3"></div>
<div class="group1 group2"></div>
<div class="group1 group3 group2"></div>

Then you just need to use an identifier to link the action to he target, and with 5,6 lines of jquery code you have everything you need.

I would recommend Apache HTTPClient.

• How to do a PUT.
• How to do a DELETE.

At the very core, the file extension you use makes no difference as to how perl interprets those files.

However, putting modules in .pm files following a certain directory structure that follows the package name provides a convenience. So, if you have a module Example::Plot::FourD and you put it in a directory Example/Plot/FourD.pm in a path in your @INC, then use and require will do the right thing when given the package name as in use Example::Plot::FourD.

The file must return true as the last statement to indicate successful execution of any initialization code, so it's customary to end such a file with 1; unless you're sure it'll return true otherwise. But it's better just to put the 1;, in case you add more statements.

If EXPR is a bareword, the require assumes a ".pm" extension and replaces "::" with "/" in the filename for you, to make it easy to load standard modules. This form of loading of modules does not risk altering your namespace.

All use does is to figure out the filename from the package name provided, require it in a BEGIN block and invoke import on the package. There is nothing preventing you from not using use but taking those steps manually.

For example, below I put the Example::Plot::FourD package in a file called t.pl, loaded it in a script in file s.pl.

C:\Temp> cat t.pl
package Example::Plot::FourD;

use strict; use warnings;

sub new { bless {} => shift }

sub something { print "something\n" }

"Example::Plot::FourD"

C:\Temp> cat s.pl
#!/usr/bin/perl
use strict; use warnings;

BEGIN {
    require 't.pl';
}

my $p = Example::Plot::FourD->new;
$p->something;


C:\Temp> s
something

This example shows that module files do not have to end in 1, any true value will do.

Here's code that may give you ideas:

<style>
.containerdiv { float: left; position: relative; } 
.cornerimage { position: absolute; top: 0; right: 0; } 
</style>

<div class="containerdiv">
    <img border="0" src="https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png" alt=""">
    <img class="cornerimage" border="0" src="http://www.gravatar.com/avatar/" alt="">
<div>

JSFiddle

I suspect that Espo's solution may be inconvenient because it requires you to position both images absolutely. You may want the first one to position itself in the flow.

Usually, there is a natural way to do that is CSS. You put position: relative on the container element, and then absolutely position children inside it. Unfortunately, you cannot put one image inside another. That's why I needed container div. Notice that I made it a float to make it autofit to its contents. Making it display: inline-block should theoretically work as well, but browser support is poor there.

EDIT: I deleted size attributes from the images to illustrate my point better. If you want the container image to have its default sizes and you don't know the size beforehand, you cannot use the background trick. If you do, it is a better way to go.

In response to: "How to convert Tue Sep 13 2016 00:00:00 GMT-0500 (Hora de verano central (México)) to dd-MM-yy in Java?", it was marked how duplicate

Try this: With java.util.Date, java.text.SimpleDateFormat, it's a simple solution.

public static void main(String[] args) throws ParseException {

    String fecha = "Tue Sep 13 2016 00:00:00 GMT-0500 (Hora de verano central (México))";
    Date f = new Date(fecha);

    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    sdf.setTimeZone(TimeZone.getTimeZone("-5GMT"));
    fecha = sdf.format(f);
    System.out.println(fecha);
}

You're trying to create a tuple, but you're just parenthesizing a string :)

Add an extra ',':

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=(dRecieved,))  # <- note extra ','
processThread.start()

Or use brackets to make a list:

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=[dRecieved])  # <- 1 element list
processThread.start()

If you notice, from the stack trace: self.__target(*self.__args, **self.__kwargs)

The *self.__args turns your string into a list of characters, passing them to the processLine function. If you pass it a one element list, it will pass that element as the first argument - in your case, the string.

Use the sizing utility classes...

• h-50 = height 50%
• h-100 = height 100%

I assume another error somewhere. Case sensitivity? Mutable classes? Non-comparable fields?

you have to rename the column to an other name because TABLE is reserved by Oracle.

You can see all reserved words of Oracle in the oracle view V$RESERVED_WORDS.

You can use this:

class myError(exception):
 pass # Or do some thing like this.
try:
 import mymodule
except ImportError as e:
 raise myError("error was occurred")

In the other posts, you have the shortcut keys, but if you want the menu option in every system, just go to Find > Quick Find All, as shown in the image attached.

Also, check the other answers for key binding to do it faster than menu clicking.

You're trying to write more data than a specific column can store. Check the sizes of the data you're trying to insert against the sizes of each of the fields.

In this case transaction_status is a varchar(10) and you're trying to store 19 characters to it.

Use df[df['B']==3]['A'].values if you just want item itself without the brackets

Use double quotation marks.

string foo = @"this ""word"" is escaped";

The answer is due to the fact that Google Chrome uses an SQLite file to save cookies. It resides under:

C:\Users\<your_username>\AppData\Local\Google\Chrome\User Data\Default\

inside Cookies file. (which is an SQLite database file)

So it's not a file stored on hard drive but a row in an SQLite database file which can be read by a third party program such as: SQLite Database Browser

EDIT: Thanks to @Chexpir, it is also good to know that the values are stored encrypted.

If you wanna add autoplay function to it. Simply replace

this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'), 

with

this.href = this.href.replace(new RegExp("watch\\?v=", "i"), 'v/') + '&autoplay=1',

also you can do the same with vimeo

this.href.replace(new RegExp("([0-9])","i"),'moogaloop.swf?clip_id=$1'),

with

this.href = this.href.replace(new RegExp("([0-9])","i"),'moogaloop.swf?clip_id=$1') + '&autoplay=1',

Synchronize the data/object that you have saved into NSUserDefaults

-(void)saveCustomObject:(Player *)object
{ 
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    NSData *myEncodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
    [prefs setObject:myEncodedObject forKey:@"testing"];
    [prefs synchronize];
}

Hope this will help you. Thanks

First of all - prerequisite for downcast is that object you are casting is of the type you are casting to. Casting with dynamic_cast will check this condition in runtime (provided that casted object has some virtual functions) and throw bad_cast or return NULL pointer on failure. Compile-time casts will not check anything and will just lead tu undefined behaviour if this prerequisite does not hold.
Now analyzing your code:

DerivedType m_derivedType = m_baseType;

Here there is no casting. You are creating a new object of type DerivedType and try to initialize it with value of m_baseType variable.

Next line is not much better:

DerivedType m_derivedType = (DerivedType)m_baseType;

Here you are creating a temporary of DerivedType type initialized with m_baseType value.

The last line

DerivedType * m_derivedType = (DerivedType*) & m_baseType;

should compile provided that BaseType is a direct or indirect public base class of DerivedType. It has two flaws anyway:

1. You use deprecated C-style cast. The proper way for such casts is
   static_cast<DerivedType *>(&m_baseType)
2. The actual type of casted object is not of DerivedType (as it was defined as BaseType m_baseType; so any use of m_derivedType pointer will result in undefined behaviour.

I was looking at cutting out SNS until I saw this in the Lambda client docs (Java version):

Client for accessing AWS Lambda. All service calls made using this client are blocking, and will not return until the service call completes.

So SNS has an obvious advantage: it's asynchronous. Your lambda won't wait for the subsequent lambda to complete.

This way I solved my problem. Hope it helps others. In my case I created a class, a field, their getter & setter and then provide the object instead of string.

Use this

public static class EncryptedData {
    private String encryptedData;

    public String getEncryptedData() {
        return encryptedData;
    }

    public void setEncryptedData(String encryptedData) {
        this.encryptedData = encryptedData;
    }
}

@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
    try {
        Path path = Paths.get(PUBLIC_KEY);
        byte[] bytes = Files.readAllBytes(path);
        PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
        PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);

        Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
        cipher.init(Cipher.PRIVATE_KEY, privateKey);
        String decryptedData = new String(cipher.doFinal(encryptedData.getEncryptedData().getBytes()));
        String[] dataArray = decryptedData.split("|");


        Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
        updateIp.invoke(null, dataArray[0], dataArray[1]);

    } catch (Exception e) {
        LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
    }

    return null;

Instead of this

@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
    try {
        Path path = Paths.get(PUBLIC_KEY);
        byte[] bytes = Files.readAllBytes(path);
        PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
        PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);

        Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
        cipher.init(Cipher.PRIVATE_KEY, privateKey);
        String decryptedData = new String(cipher.doFinal(encryptedData.getBytes()));
        String[] dataArray = decryptedData.split("|");


        Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
        updateIp.invoke(null, dataArray[0], dataArray[1]);

    } catch (Exception e) {
        LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
    }

    return null;
}

According to this post, it's much better now:

// pick out one album
JObject jalbum = albums[0] as JObject;

// Copy to a static Album instance
Album album = jalbum.ToObject<Album>();

Django is designed to be easely used to deliver web pages. If you are not confortable with this perhaps you should use another solution.

I'm writting the root or common operations on the model (to have the same interface) and the others on the controller of the model. If I need an operation from other model I import its controller.

This approach it's enough for me and the complexity of my applications.

Hedde's response is an example that shows the flexibility of django and python itself.

Very interesting question anyway!

You edit an element's value by editing it's .value property.

"I actually tried to had a normal objective discusssion over pros and cons of 1., using framework over pure javascript and 2., jquery vs. others, since jQuery seems to be easiest to work with with quickest learning curve."

Using any framework because you don't want to actually learn the underlying language is absolutely wrong not only for JavaScript, but for any other programming language.

"Is there any reason (besides browser sniffing and personal "hate" against John Resig) why jQuery is wrong?"

Most of the hate agains it comes from the exaggerated fanboyism which pollutes forums with "use jQuery" as an answer for every single JavaScript question and the overuse which produces code in which simple statements such as declaring a variable are done through library calls.

Nevertheless, there are also some legit technical issues such as the shared guilt in producing illegible code and overhead. Of course those two are aggravated by the lack of developer proficiency rather than the library itself.

I had the same problem that occurred after I restored data from a postgres dumped db.

My dump file had the command below from where things started going south.

    SELECT pg_catalog.set_config('search_path', '', false);

Solutions:

1. Probably remove it or change that false to be true.
2. Create a private schema that will be used to access all the tables.

The command above simply deactivates all the publicly accessible schemas.

And this one: http://forum.xda-developers.com/showthread.php?t=1405639

After learning what it is all about, I thought to write a hopefully simpler explanation via analogy:

Summary: What is a hashcode?

• It's a fingerprint. We can use this finger print to identify people of interest.

Read below for more details:

Think of a Hashcode as us trying to To Uniquely Identify Someone

I am a detective, on the look out for a criminal. Let us call him Mr Cruel. (He was a notorious murderer when I was a kid -- he broke into a house kidnapped and murdered a poor girl, dumped her body and he's still out on the loose - but that's a separate matter). Mr Cruel has certain peculiar characteristics that I can use to uniquely identify him amongst a sea of people. We have 25 million people in Australia. One of them is Mr Cruel. How can we find him?

Bad ways of Identifying Mr Cruel

Apparently Mr Cruel has blue eyes. That's not much help because almost half the population in Australia also has blue eyes.

Good ways of Identifying Mr Cruel

What else can i use? I know: I will use a fingerprint!

Advantages:

• It is really really hard for two people to have the same finger print (not impossible, but extremely unlikely).
• Mr Cruel's fingerprint will never change.
• Every single part of Mr Cruel's entire being: his looks, hair colour, personality, eating habits etc must (ideally) be reflected in his fingerprint, such that if he has a brother (who is very similar but not the same) - then both should have different finger prints. I say "should" because we cannot guarantee 100% that two people in this world will have different fingerprints.
• But we can always guarantee that Mr Cruel will always have the same finger print - and that his fingerprint will NEVER change.

The above characteristics generally make for good hash functions.

So what's the deal with 'Collisions'?

So imagine if I get a lead and I find someone matching Mr Cruel's fingerprints. Does this mean I have found Mr Cruel?

........perhaps! I must take a closer look. If i am using SHA256 (a hashing function) and I am looking in a small town with only 5 people - then there is a very good chance I found him! But if I am using MD5 (another famous hashing function) and checking for fingerprints in a town with +2^1000 people, then it is a fairly good possibility that two entirely different people might have the same fingerprint.

So what is the benefit of all this anyways?

The only real benefit of hashcodes is if you want to put something in a hash table - and with hash tables you'd want to find objects quickly - and that's where the hash code comes in. They allow you to find things in hash tables really quickly. It's a hack that massively improves performance, but at a small expense of accuracy.

So let's imagine we have a hash table filled with people - 25 million suspects in Australia. Mr Cruel is somewhere in there..... How can we find him really quickly? We need to sort through them all: to find a potential match, or to otherwise acquit potential suspects. You don't want to consider each person's unique characteristics because that would take too much time. What would you use instead? You'd use a hashcode! A hashcode can tell you if two people are different. Whether Joe Bloggs is NOT Mr Cruel. If the prints don't match then you know it's definitely NOT Mr Cruel. But, if the finger prints do match then depending on the hash function you used, chances are already fairly good you found your man. But it's not 100%. The only way you can be certain is to investigate further: (i) did he/she have an opportunity/motive, (ii) witnesses etc etc.

When you are using computers if two objects have the same hash code value, then you again need to investigate further whether they are truly equal. e.g. You'd have to check whether the objects have e.g. the same height, same weight etc, if the integers are the same, or if the customer_id is a match, and then come to the conclusion whether they are the same. this is typically done perhaps by implementing an IComparer or IEquality interfaces.

Key Summary

So basically a hashcode is a finger print.

1. Two different people/objects can theoretically still have the same fingerprint. Or in other words. If you have two fingerprints that are the same.........then they need not both come from the same person/object.
2. Buuuuuut, the same person/object will always return the same fingerprint.
3. Which means that if two objects return different hash codes then you know for 100% certainty that those objects are different.

It takes a good 3 minutes to get your head around the above. Perhaps read it a few times till it makes sense. I hope this helps someone because it took a lot of grief for me to learn it all!

Try this one.

Add this code in Your View file

$CI     = & get_instance();
$result = $CI->FindFurnishName($pera);

Add code in Your controller File

public function FindFurnishName($furnish_filter)

{

$FindFurnishName        = $this->index_modal->FindFurnishName($furnish_filter);  
$FindFurnishName_val    = '';
foreach($FindFurnishName as $AllRea)
{
    $FindFurnishName_val  .= ",".$AllRea->name;
}
return ltrim($FindFurnishName_val,',');

}

where

1. FindFurnishName is name of function which is define in Your Controller.
2. $pera is a option ( as your need).

In C# 9 Microsoft will introduce a new way to have properties set only on initialization using the init; method like so:

public class Person
{
  public string firstName { get; init; }
  public string lastName { get; init; }
}

This way, you can assign values when initializing a new object:

var person = new Person
{
  firstname = "John",
  lastName = "Doe"
}

But later on, you cannot change it:

person.lastName = "Denver"; // throws a compiler error

To sum up:

• HashMap: Lookup-array structure, based on hashCode(), equals() implementations, O(1) runtime complexity for inserting and searching, unsorted
• TreeMap: Tree structure, based on compareTo() implementation, O(log(N)) runtime complexity for inserting and searching, sorted

Taken from: HashMap vs. TreeMap

1. Download apache-maven-3.3.9-bin.zip file and extract it.

2. Then set system variable M2_HOME = B:\sql software\apache-maven-3.3.9 or as appropriate

3. Also set variable M2 = %M2_HOME%\bin

4. Open CMD and write mvn

I solved thank you

Yes it is possible.

The technique is described below

http://jquery.tiddlywiki.org/twFile.html

var otherInput = $(this).closest('.row').find('.inputQty');

That goes up to a row level, then back down to .inputQty.

In iOS 6, the

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation

is deprecated.

Use following code instead

- (void)locationManager:(CLLocationManager *)manager
     didUpdateLocations:(NSArray *)locations {
    CLLocation *location = [locations lastObject];
    NSLog(@"lat%f - lon%f", location.coordinate.latitude, location.coordinate.longitude);
}

For iOS 6~8, the above method is still necessary, but you have to handle authorization.

_locationManager = [CLLocationManager new];
_locationManager.delegate = self;
_locationManager.distanceFilter = kCLDistanceFilterNone;
_locationManager.desiredAccuracy = kCLLocationAccuracyBest;

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0 &&
    [CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorizedWhenInUse
    //[CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorizedAlways
   ) {
     // Will open an confirm dialog to get user's approval 
    [_locationManager requestWhenInUseAuthorization]; 
    //[_locationManager requestAlwaysAuthorization];
} else {
    [_locationManager startUpdatingLocation]; //Will update location immediately 
}

This is the delegate method which handle user's authorization

#pragma mark - CLLocationManagerDelegate
- (void)locationManager:(CLLocationManager*)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
    switch (status) {
    case kCLAuthorizationStatusNotDetermined: {
        NSLog(@"User still thinking..");
    } break;
    case kCLAuthorizationStatusDenied: {
        NSLog(@"User hates you");
    } break;
    case kCLAuthorizationStatusAuthorizedWhenInUse:
    case kCLAuthorizationStatusAuthorizedAlways: {
        [_locationManager startUpdatingLocation]; //Will update location immediately
    } break;
    default:
        break;
    }
}

You can do this way :

TimeSpan duration = new TimeSpan(tickCount)
double minutes = duration.TotalMinutes;

regex: /^[a-zA-Z0-9_.]$/i

This works

There are a couple of ways:

To delete it directly:

SomeModel.objects.filter(id=id).delete()

To delete it from an instance:

instance = SomeModel.objects.get(id=id)
instance.delete()

Can you try this, readfile need the full file path.

In Access, click Create > Module and paste in the following code

Public Function ConvertMyStringToDateTime(strIn As String) As Date
ConvertMyStringToDateTime = CDate( _
        Mid(strIn, 1, 4) & "-" & Mid(strIn, 5, 2) & "-" & Mid(strIn, 7, 2) & " " & _
        Mid(strIn, 9, 2) & ":" & Mid(strIn, 11, 2) & ":" & Mid(strIn, 13, 2))
End Function

Hit Ctrl+S and save the module as modDateConversion.

Now try using a query like

Select * from Events
Where Events.[Date] > ConvertMyStringToDateTime("20130423014854")

--- Edit ---

Alternative solution avoiding user-defined VBA function:

SELECT * FROM Events
WHERE Format(Events.[Date],'yyyyMMddHhNnSs') > '20130423014854'

There's no difference, in fact map is implemented in C as rb_ary_collect and enum_collect (eg. there is a difference between map on an array and on any other enum, but no difference between map and collect).

Why do both map and collect exist in Ruby? The map function has many naming conventions in different languages. Wikipedia provides an overview:

The map function originated in functional programming languages but is today supported (or may be defined) in many procedural, object oriented, and multi-paradigm languages as well: In C++'s Standard Template Library, it is called transform, in C# (3.0)'s LINQ library, it is provided as an extension method called Select. Map is also a frequently used operation in high level languages such as Perl, Python and Ruby; the operation is called map in all three of these languages. A collect alias for map is also provided in Ruby (from Smalltalk) [emphasis mine]. Common Lisp provides a family of map-like functions; the one corresponding to the behavior described here is called mapcar (-car indicating access using the CAR operation).

Ruby provides an alias for programmers from the Smalltalk world to feel more at home.

Why is there a different implementation for arrays and enums? An enum is a generalized iteration structure, which means that there is no way in which Ruby can predict what the next element can be (you can define infinite enums, see Prime for an example). Therefore it must call a function to get each successive element (typically this will be the each method).

Arrays are the most common collection so it is reasonable to optimize their performance. Since Ruby knows a lot about how arrays work it doesn't have to call each but can only use simple pointer manipulation which is significantly faster.

Similar optimizations exist for a number of Array methods like zip or count.

in my case using Docker, my .env file was not copied, so the following env vars were not set:

.env.local: FLASK_APP=src/app.py

so in my Dockerfile i had to include:

FROM deploy as dev
COPY env ./env

which was referenced in docker-compose.yml

env_file: ./env/.env.local

another thing i had to pay attention to is the path variable to ensure my environment is used

ENV PATH $CONDA_DIR/envs/:my_environment_name_from_yml_file:/bin:$CONDA_DIR/bin:$PATH```

Swift 3 Solution:

private func createImagesFolder() {
        // path to documents directory
        let documentDirectoryPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first
        if let documentDirectoryPath = documentDirectoryPath {
            // create the custom folder path
            let imagesDirectoryPath = documentDirectoryPath.appending("/images")
            let fileManager = FileManager.default
            if !fileManager.fileExists(atPath: imagesDirectoryPath) {
                do {
                    try fileManager.createDirectory(atPath: imagesDirectoryPath,
                                                    withIntermediateDirectories: false,
                                                    attributes: nil)
                } catch {
                    print("Error creating images folder in documents dir: \(error)")
                }
            }
        }
    }

Just use print_r ; ) Read the documentation:

If you would like to capture the output of print_r(), use the return parameter. When this parameter is set to TRUE, print_r() will return the information rather than print it.

So this is one possibility:

$fp = fopen('file.txt', 'w');
fwrite($fp, print_r($array, TRUE));
fclose($fp);

I wrote this in an ajax view, but it is a more expansive answer giving the list of currently logged in and logged out users.

The is_authenticated attribute always returns True for my users, which I suppose is expected since it only checks for AnonymousUsers, but that proves useless if you were to say develop a chat app where you need logged in users displayed.

This checks for expired sessions and then figures out which user they belong to based on the decoded _auth_user_id attribute:

def ajax_find_logged_in_users(request, client_url):
    """
    Figure out which users are authenticated in the system or not.
    Is a logical way to check if a user has an expired session (i.e. they are not logged in)
    :param request:
    :param client_url:
    :return:
    """
    # query non-expired sessions
    sessions = Session.objects.filter(expire_date__gte=timezone.now())
    user_id_list = []
    # build list of user ids from query
    for session in sessions:
        data = session.get_decoded()
        # if the user is authenticated
        if data.get('_auth_user_id'):
            user_id_list.append(data.get('_auth_user_id'))

    # gather the logged in people from the list of pks
    logged_in_users = CustomUser.objects.filter(id__in=user_id_list)
    list_of_logged_in_users = [{user.id: user.get_name()} for user in logged_in_users]

    # Query all logged in staff users based on id list
    all_staff_users = CustomUser.objects.filter(is_resident=False, is_active=True, is_superuser=False)
    logged_out_users = list()
    # for some reason exclude() would not work correctly, so I did this the long way.
    for user in all_staff_users:
        if user not in logged_in_users:
            logged_out_users.append(user)
    list_of_logged_out_users = [{user.id: user.get_name()} for user in logged_out_users]

    # return the ajax response
    data = {
        'logged_in_users': list_of_logged_in_users,
        'logged_out_users': list_of_logged_out_users,
    }

How to auto increment by one, starting at 10 in MySQL:

create table foobar(
  id             INT PRIMARY KEY AUTO_INCREMENT,
  moobar         VARCHAR(500)
); 
ALTER TABLE foobar AUTO_INCREMENT=10;

INSERT INTO foobar(moobar) values ("abc");
INSERT INTO foobar(moobar) values ("def");
INSERT INTO foobar(moobar) values ("xyz");

select * from foobar;

'10', 'abc'
'11', 'def'
'12', 'xyz'

This auto increments the id column by one starting at 10.

Auto increment in MySQL by 5, starting at 10:

drop table foobar
create table foobar(
  id             INT PRIMARY KEY AUTO_INCREMENT,
  moobar         VARCHAR(500)
); 
SET @@auto_increment_increment=5;
ALTER TABLE foobar AUTO_INCREMENT=10;

INSERT INTO foobar(moobar) values ("abc");
INSERT INTO foobar(moobar) values ("def");
INSERT INTO foobar(moobar) values ("xyz");

select * from foobar;
'11', 'abc'
'16', 'def'
'21', 'xyz'

This auto increments the id column by 5 each time, starting at 10.

rapidjson is a C++ JSON parser/generator designed to be fast and small memory footprint.

There is a performance comparison with YAJL and JsonCPP.

Update:

I created an open source project Native JSON benchmark, which evaluates 29 (and increasing) C/C++ JSON libraries, in terms of conformance and performance. This should be an useful reference.

I had pip referring by default to pip3, which made me download the libs for python3. On the contrary I launched the shell as python (which opened python 2) and the library wasn't installed there obviously.

Once I matched the names pip3 -> python3, pip -> python (2) all worked.

It is because the Creation was delayed. If you want the picture to be loaded immediately, you can simply add this code into the init phase.

src.CacheOption = BitmapCacheOption.OnLoad;

like this:

src.BeginInit();
src.UriSource = new Uri("picture.jpg", UriKind.Relative);
src.CacheOption = BitmapCacheOption.OnLoad;
src.EndInit();

No amount of cleaning, closing/reopening the project&IDE, removing/adding the JRE in build path worked for me.

The solution I found was to remove the project from Eclipse (not from disk), remove the project's Eclipse files from the disk, and import into Eclipse again. That worked.

It is even faster if you are using Maven:

1. Close Eclipse (no need to remove the project)
2. Run mvn clean eclipse:clean eclipse:eclipse
3. Open Eclipse. Your project is still present and the problem should be gone.

If you want to know if the string is found in the array at all, try this function:

Function IsInArray(stringToBeFound As String, arr As Variant) As Boolean
  IsInArray = (UBound(Filter(arr, stringToBeFound)) > -1)
End Function

As SeanC points out, this must be a 1-D array.

Example:

Sub Test()
  Dim arr As Variant
  arr = Split("abc,def,ghi,jkl", ",")
  Debug.Print IsInArray("ghi", arr)
End Sub

(Below code updated based on comment from HansUp)

If you want the index of the matching element in the array, try this:

Function IsInArray(stringToBeFound As String, arr As Variant) As Long
  Dim i As Long
  ' default return value if value not found in array
  IsInArray = -1

  For i = LBound(arr) To UBound(arr)
    If StrComp(stringToBeFound, arr(i), vbTextCompare) = 0 Then
      IsInArray = i
      Exit For
    End If
  Next i
End Function

This also assumes a 1-D array. Keep in mind LBound and UBound are zero-based so an index of 2 means the third element, not the second.

Example:

Sub Test()
  Dim arr As Variant
  arr = Split("abc,def,ghi,jkl", ",")
  Debug.Print (IsInArray("ghi", arr) > -1)
End Sub

If you have a specific example in mind, please update your question with it, otherwise example code might not apply to your situation.

There is also this approach seen on SuperUser which uses the sc command line instead of modifying the registry:

sc config <service name> binPath= <binary path>

Note: the space after binPath= is important. You can also query the current configuration using:

sc qc <service name>

This displays output similar to:

[SC] QueryServiceConfig SUCCESS

SERVICE_NAME: ServiceName

    TYPE               : 10  WIN32_OWN_PROCESS
    START_TYPE         : 2   AUTO_START
    ERROR_CONTROL      : 1   NORMAL
    BINARY_PATH_NAME   : C:\Services\ServiceName
    LOAD_ORDER_GROUP   :
    TAG                : 0
    DISPLAY_NAME       : <Display name>
    DEPENDENCIES       :
    SERVICE_START_NAME : user-name@domain-name

Try this:

$("#myId > UL > LI")

You don't mention the API version, but since API 11 there's the method WebViewClient.shouldInterceptRequest

Maybe this could help?

I might've over-engineered my own solution without realizing that Type.valueOf("enum string") actually existed.

I guess it gives more granular control but I'm not sure it's really necessary.

public enum Type {
    DEBIT,
    CREDIT;

    public static Map<String, Type> typeMapping = Maps.newHashMap();
    static {
        typeMapping.put(DEBIT.name(), DEBIT);
        typeMapping.put(CREDIT.name(), CREDIT);
    }

    public static Type getType(String typeName) {
        if (typeMapping.get(typeName) == null) {
            throw new RuntimeException(String.format("There is no Type mapping with name (%s)"));
        }
        return typeMapping.get(typeName);
    }
}

I guess you're exchanging IllegalArgumentException for RuntimeException (or whatever exception you wish to throw) which could potentially clean up code.

I think the OP's question is solved by deleting the ~/.ssh/known_hosts (which was a folder, not a file). But for other's who might be having this issue, I noticed that one of my servers had weird permissions (400):

-r--------. 1 user user 396 Jan 7 11:12 /home/user/.ssh/known_hosts

So I solved this by adding owner/user PLUS write.

chmod u+w ~/.ssh/known_hosts

Thus. ~/.ssh/known_hosts needs to be a flat file, and must be owned by you, and you need to be able to read and write to it.

You could always declare known_hosts bankruptcy, delete it, and continue doing things as normal, and connecting to things (git / ssh) will regenerate a new known_hosts that should work just fine.

Since i have found issue uploading file in IE browser i would suggest to handle it like this.

View

@using (Html.BeginForm("UploadFile", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <input type="file" name="file" />
    <input type="submit" value="Submit" />
}

Controller

public class HomeController : Controller
{
    public ActionResult UploadFile()
    {
        return View();
    }

    [HttpPost]
    public ActionResult UploadFile(MyModal Modal)
    {
            string DocumentName = string.Empty;
            string Description = string.Empty;

            if (!String.IsNullOrEmpty(Request.Form["DocumentName"].ToString()))
                DocumentName = Request.Form["DocumentName"].ToString();
            if (!String.IsNullOrEmpty(Request.Form["Description"].ToString()))
                Description = Request.Form["Description"].ToString();

            if (!String.IsNullOrEmpty(Request.Form["FileName"].ToString()))
                UploadedDocument = Request.Form["FileName"].ToString();

            HttpFileCollectionBase files = Request.Files;

            string filePath = Server.MapPath("~/Root/Documents/");
            if (!(Directory.Exists(filePath)))

If you read the help file for ?boxplot, you'll see there is a names= parameter.

     boxplot(apple, banana, watermelon, names=c("apple","banana","watermelon"))

 JsonNode node = mapper.readValue("[{\"id\":\"value11\",\"name\": \"value12\",\"qty\":\"value13\"},"

 System.out.println("id : "+node.findValues("id").get(0).asText());

this also done the trick.

Unfortunately you cannot do it in one command. There is an open issue for the very feature.

Currently you'll have to do it by hand. If you need to do it often, you can create a custom gradle plugin, or just prepare your own project skeleton and copy it when needed.

EDIT

The JIRA issue mentioned above has been resolved, as of May 1, 2013, and fixed in 1.7-rc-1. The documentation on the Build Init Plugin is available, although it indicates that this feature is still in the "incubating" lifecycle.

Here is a sample to find if there are match elements in another list

List<int> nums1 = new List<int> { 2, 4, 6, 8, 10 };
List<int> nums2 = new List<int> { 1, 3, 6, 9, 12};

if (nums1.Any(x => nums2.Any(y => y == x)))
{
    Console.WriteLine("There are equal elements");
}
else
{
    Console.WriteLine("No Match Found!");
}

If you're in charge (or have any control over the web service), get them to add a unique root element!

If you can't change that at all, then you can do a bit of regex or string-splitting to parse each and pass each element to your XML Reader.

Alternatively, you could manually add a junk root element, by prefixing an opening tag and suffixing a closing tag.

No there isn't. See https://jira.mongodb.org/browse/SERVER-701

Unfortunately, this is not an simple feature for us to implement due to the way that database metadata is stored in the original (default) storage engine. In MMAPv1 files, the namespace (e.g.: dbName.collection) that describes every single collection and index includes the database name, so to rename a set of database files, every single namespace string would have to be rewritten. This impacts:

• the .ns file
• every single numbered file for the collection
• the namespace for every index
• internal unique names of each collection and index
• contents of system.namespaces and system.indexes (or their equivalents in the future)
• other locations I may be missing

This is just to accomplish a rename of a single database in a standalone mongod instance. For replica sets the above would need to be done on every replica node, plus on each node every single oplog entry that refers this database would have to be somehow invalidated or rewritten, and then if it's a sharded cluster, one also needs to add these changes to every shard if the DB is sharded, plus the config servers have all the shard metadata in terms of namespaces with their full names.

There would be absolutely no way to do this on a live system.

To do it offline, it would require re-writing every single database file to accommodate the new name, and at that point it would be as slow as the current "copydb" command...

I faced the same issue today,

And solved it easily by following points

1) Start the StandAlone SDK manager (To open the standalone sdk manager - Tools>Android>SDKManager> at Bottom YOu will see a link to launch StandAlone SDK manager)

2) Delete tha package of SDK Build Tools that you have already installed for e.g 24.0.0 rc4.

3) Close the standalone SDK manager then Restart Android Studio.

4) Once after restart the gradle will start building the project and you will get an alert download the package of SDK build tool and Sync. CLick on that and you will start downloading like that...

I hope this helps

If i am understanding your question, would this work? (you will have to replace with your actual column and table names)

SELECT time_col, COUNT(time_col) As Count
FROM time_table
GROUP BY time_col
WHERE activity_col = 3

Node is missing from the SYSTEM PATH, try this in your command line

SET PATH=C:\Program Files\Nodejs;%PATH%

and then try running node

To set this system wide you need to set in the system settings - cf - http://banagale.com/changing-your-system-path-in-windows-vista.htm

To be very clean, create a new system variable NODEJS

NODEJS="C:\Program Files\Nodejs"

Then edit the PATH in system variables and add %NODEJS%

PATH=%NODEJS%;...

In addition to the answers above, you can check the type of object using type(plt.subplots()) which returns a tuple, on the other hand, type(plt.subplot()) returns matplotlib.axes._subplots.AxesSubplot which you can't unpack.

They're apples and oranges. You don't want to compare them. They're two different things. AngularJs has already jQuery lite built in which allows you to perform basic DOM manipulation without even including the full blown jQuery version.

jQuery is all about DOM manipulation. It solves all the cross browser pain otherwise you will have to deal with but it's not a framework that allows you to divide your app into components like AngularJS.

A nice thing about AngularJs is that it allows you to separate/isolate the DOM manipulation in the directives. There are built-in directives ready for you to use such as ng-click. You can create your own custom directives that will contain all your view logic or DOM manipulation so you don't end up mingle DOM manipulation code in the controllers or services that should take care of the business logic.

Angular breaks down your app into - Controllers - Services - Views - etc.

and there is one more thing, that's the directive. It's an attribute you can attach to any DOM element and you can go nuts with jQuery within it without worrying about your jQuery ever conflicts with AngularJs components or messes up with its architecture.

I heard from a meetup I attended, one of the founders of Angular said they worked really hard to separate out the DOM manipulation so do not try to include them back in.

If you are on version >= Android 8.1 (Oreo) while using a Notification channel, set its importance to high:

int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);

You can simply use JavaScripts join() function for that. This would simply look like a.value.join(','). The output would be a string though.

I think who the best mix for html & Css for quick and clean mod is :

<table class="table text-center">
<thead>
        <tr>                    
        <th class="text-center">Uno</th>
        <th class="text-center">Due</th>
        <th class="text-center">Tre</th>
        <th class="text-center">Quattro</th>
    </tr>
</thead>
<tbody>
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
        <td>4</td>
    </tr>
</tbody>
</table>

close the <table> init tag then copy where you want :) I hope it can be useful Have a good day w stackoverflow

p.s. Bootstrap v3.2.0

Just add:

import os

in the beginning, before:

from settings import PROJECT_ROOT

This will import the python's module os, which apparently is used later in the code of your module without being imported.

public static void main(String[] args) {
    int[] toyNumber = new int[] {5};
    NewClass temp = new NewClass();
    temp.play(toyNumber);
    System.out.println("Toy number in main " + toyNumber[0]);
}

void play(int[] toyNumber){
    System.out.println("Toy number in play " + toyNumber[0]);
    toyNumber[0]++;
    System.out.println("Toy number in play after increement " + toyNumber[0]);
}

First, let's clear up some terminology: "asynchronous" (async) means that it may yield control back to the calling thread before it starts. In an async method, those "yield" points are await expressions.

This is very different than the term "asynchronous", as (mis)used by the MSDN documentation for years to mean "executes on a background thread".

To futher confuse the issue, async is very different than "awaitable"; there are some async methods whose return types are not awaitable, and many methods returning awaitable types that are not async.

Enough about what they aren't; here's what they are:

• The async keyword allows an asynchronous method (that is, it allows await expressions). async methods may return Task, Task<T>, or (if you must) void.
• Any type that follows a certain pattern can be awaitable. The most common awaitable types are Task and Task<T>.

So, if we reformulate your question to "how can I run an operation on a background thread in a way that it's awaitable", the answer is to use Task.Run:

private Task<int> DoWorkAsync() // No async because the method does not need await
{
  return Task.Run(() =>
  {
    return 1 + 2;
  });
}

(But this pattern is a poor approach; see below).

But if your question is "how do I create an async method that can yield back to its caller instead of blocking", the answer is to declare the method async and use await for its "yielding" points:

private async Task<int> GetWebPageHtmlSizeAsync()
{
  var client = new HttpClient();
  var html = await client.GetAsync("http://www.example.com/");
  return html.Length;
}

So, the basic pattern of things is to have async code depend on "awaitables" in its await expressions. These "awaitables" can be other async methods or just regular methods returning awaitables. Regular methods returning Task/Task<T> can use Task.Run to execute code on a background thread, or (more commonly) they can use TaskCompletionSource<T> or one of its shortcuts (TaskFactory.FromAsync, Task.FromResult, etc). I don't recommend wrapping an entire method in Task.Run; synchronous methods should have synchronous signatures, and it should be left up to the consumer whether it should be wrapped in a Task.Run:

private int DoWork()
{
  return 1 + 2;
}

private void MoreSynchronousProcessing()
{
  // Execute it directly (synchronously), since we are also a synchronous method.
  var result = DoWork();
  ...
}

private async Task DoVariousThingsFromTheUIThreadAsync()
{
  // I have a bunch of async work to do, and I am executed on the UI thread.
  var result = await Task.Run(() => DoWork());
  ...
}

I have an async/await intro on my blog; at the end are some good followup resources. The MSDN docs for async are unusually good, too.

After doing a git fetch, you can run git status to show how many commits the local branch is ahead or behind of the remote version of the branch.

This won't show you how many commits it is ahead or behind of a different branch though. Your options are the full diff, looking at github, or using a solution like Vimhsa linked above: Git status over all repo's

J Bryan Price, a good example, but there are shortcomings

{\"response\":[123, 456, {\"name\":\"John\"}, {\"count\":3}]}

after formatting

{
    "response" : [
        123,
         456,
         {
            "name" : "John"

You can make a path for your file as bellow:

string path = "fileName-"+DateTime.Now.ToString("yyyy-dd-M--HH-mm-ss") + ".txt";

it works well on Edge and Chrome:

  width: fit-content;
  height: fit-content;

Try this:

Re-posted as an answer: Found an alternative (Tested in Win8):

cmdkey /generic:"<server>" /user:"<user>" /pass:"<pass>"

Run that and if you run:

mstsc /v:<server>

You should not get an authentication prompt.

Add this at the top of your file:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

DANGEROUS This disables HTTPS / SSL / TLS checking across your entire node.js environment. Please see the solution using an https agent below.

You can also use TimerTask for that.

Here is an method

private void setTimerTask() {
    long delay = 3000;
    long periodToRepeat = 60 * 1000; /* 1 mint */
    Timer timer = new Timer();
    timer.schedule(new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                 //   do your stuff here.
                }
            });
        }
    }, 3000, 3000);
}

You could can use git rebase to rewrite the commit history. This can be potentially destructive to your changes, so use with care.

First commit your "amend" change as a normal commit. Then do an interactive rebase starting on the parent of your oldest commit

git rebase -i 47175e84c2cb7e47520f7dde824718eae3624550^

This will fire up your editor with all commits. Reorder them so your "amend" commit comes below the one you want to amend. Then replace the first word on the line with the "amend" commit with s which will combine (s quash) it with the commit before. Save and exit your editor and follow the instructions.

To me the solution was to go to

Run > Edit Configuration > Defaults > Python

then manage the

• "Add content roots to PYTHONPATH" and
• "Add source root to PYTHONPATH"

checkboxes, as well as setting the "Working directory" field.

If you have set up your own Run/Debug Configurations then you might want to go to

Run > Edit Configuration > Python > [Whatever you called your config]

and edit it there.

My problem was that I wanted to have my whole repository included in my PyCharm 2016.2 project, but only a subfolder was the actual python source code root. I added it as "Source Root" by right clicking the folder then

Mark directory as > Source Root

Then unchecking "Add content roots to PYTHONPATH" and checking "Add source root to PYTHONPATH" in the Run/Debug config menu. I then checked the folder pathing by doing:

import sys
logger.info(sys.path)

This outputed:

[
    '/usr/local/my_project_root/my_sources_root', 
    '/usr/local/my_project_root/my_sources_root', 
    '/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu', 
    '/usr/lib/python3.4/lib-dynload', 
    '/usr/local/lib/python3.4/dist-packages', 
    '/usr/lib/python3/dist-packages'
]

However, without the fix it said:

[
    '/usr/local/my_project_root/my_sources_root', 
    '/usr/local/my_project_root',                   <-- NOT WANTED
    '/usr/lib/python3.4', 
    '/usr/lib/python3.4/plat-x86_64-linux-gnu', 
    '/usr/lib/python3.4/lib-dynload', 
    '/usr/local/lib/python3.4/dist-packages', 
    '/usr/lib/python3/dist-packages'
]

Which meant I got the project root folder included. This messed up the pathing for me.

I think what you looking for is "joinSub". It's supported from laravel ^5.6. If you using laravel version below 5.6 you can also register it as macro in your app service provider file. like this https://github.com/teamtnt/laravel-scout-tntsearch-driver/issues/171#issuecomment-413062522

$subquery = DB::table('catch-text')
            ->select(DB::raw("user_id,MAX(created_at) as MaxDate"))
            ->groupBy('user_id');

$query = User::joinSub($subquery,'MaxDates',function($join){
          $join->on('users.id','=','MaxDates.user_id');
})->select(['users.*','MaxDates.*']);

I built a gem hash_parser that first checks if a hash is safe or not using ruby_parser gem. Only then, it applies the eval.

You can use it as

require 'hash_parser'

# this executes successfully
a = "{ :key_a => { :key_1a => 'value_1a', :key_2a => 'value_2a' }, 
       :key_b => { :key_1b => 'value_1b' } }"
p HashParser.new.safe_load(a)

# this throws a HashParser::BadHash exception
a = "{ :key_a => system('ls') }"
p HashParser.new.safe_load(a)

The tests in https://github.com/bibstha/ruby_hash_parser/blob/master/test/test_hash_parser.rb give you more examples of the things I've tested to make sure eval is safe.

To add a bit to accepted answer ...

If you get an UnfinishedStubbingException, be sure to set the method to be stubbed after the when closure, which is different than when you write Mockito.when

Mockito.doNothing().when(mock).method()    //method is declared after 'when' closes

Mockito.when(mock.method()).thenReturn(something)   //method is declared inside 'when'

Place this at the top of your script. It will cause the script to prompt the user for a password. The resulting password can then be used elsewhere in your script via $pw.

   Param(
     [Parameter(Mandatory=$true, Position=0, HelpMessage="Password?")]
     [SecureString]$password
   )

   $pw = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($password))

If you want to debug and see the value of the password you just read, use:

   write-host $pw

Actually your Windows firewall is blocking the connection. You need to enter these commands into cmd.exe from Administrator.

netsh advfirewall firewall add rule name="FTP" dir=in action=allow program=%SystemRoot%\System32\ftp.exe enable=yes protocol=tcp
netsh advfirewall firewall add rule name="FTP" dir=in action=allow program=%SystemRoot%\System32\ftp.exe enable=yes protocol=udp

In case something goes wrong then you can revert by this:

netsh advfirewall firewall delete rule name="FTP" program=%SystemRoot%\System32\ftp.exe

Package graphql-type-json supports custom-scalars type JSON. Use it can show all the field of your json objects. Here is the link of the example in ApolloGraphql Server. https://www.apollographql.com/docs/apollo-server/schema/scalars-enums/#custom-scalars

To check if one or more columns all exist, you can use set.issubset, as in:

if set(['A','C']).issubset(df.columns):
   df['sum'] = df['A'] + df['C']                

As @brianpck points out in a comment, set([]) can alternatively be constructed with curly braces,

if {'A', 'C'}.issubset(df.columns):

See this question for a discussion of the curly-braces syntax.

Or, you can use a list comprehension, as in:

if all([item in df.columns for item in ['A','C']]):

To have GIT_SSH_COMMAND environment variable work under Windows instead of:

As of Feb 2018, fetch() can be cancelled with the code below on Chrome (read Using Readable Streams to enable Firefox support). No error is thrown for catch() to pick up, and this is a temporary solution until AbortController is fully adopted.

})
.then(response => response.blob())
.then(data => console.log('Download ended. Bytes downloaded:', data.size))

Let me first highlight three different ways for similar purpose.

length -- arrays (int[], double[], String[]) -- to know the length of the arrays

length() -- String related Object (String, StringBuilder, etc) -- to know the length of the String

size() -- Collection Object (ArrayList, Set, etc) -- to know the size of the Collection

Now forget about length() consider just length and size().

length is not a method, so it completely makes sense that it will not work on objects. It only works on arrays.
size() its name describes it better and as it is a method, it will be used in the case of those objects who work with collection (collection frameworks) as I said up there.

Now come to length():
String is not a primitive array (so we can't use .length) and also not a Collection (so we cant use .size()) that's why we also need a different one which is length() (keep the differences and serve the purpose).

As answer to Why?
I find it useful, easy to remember and use and friendly.

Swift 4 and Xcode Version 9+

you should try with figaspect. It works for me. From the docs:

Create a figure with specified aspect ratio. If arg is a number, use that aspect ratio. > If arg is an array, figaspect will determine the width and height for a figure that would fit array preserving aspect ratio. The figure width, height in inches are returned. Be sure to create an axes with equal with and height, eg

Example usage:

  # make a figure twice as tall as it is wide
  w, h = figaspect(2.)
  fig = Figure(figsize=(w,h))
  ax = fig.add_axes([0.1, 0.1, 0.8, 0.8])
  ax.imshow(A, **kwargs)

  # make a figure with the proper aspect for an array
  A = rand(5,3)
  w, h = figaspect(A)
  fig = Figure(figsize=(w,h))
  ax = fig.add_axes([0.1, 0.1, 0.8, 0.8])
  ax.imshow(A, **kwargs)

Edit: I am not sure of what you are looking for. The above code changes the canvas (the plot size). If you want to change the size of the matplotlib window, of the figure, then use:

In [68]: f = figure(figsize=(5,1))

this does produce a window of 5x1 (wxh).

In 2015 I would go with:

• For small scripts: The js editor + jsHint plugin
• For large code bases: TypeScript Eclipse plugin, or a similar transpiled language... I only know that TypeScript works well in Eclipse.

Of course you may want to keep JS for easy project setup and to avoid the transpilation process... there is no ultimate solution.

nano /usr/local/Cellar/mysql/5.6.20_1/my.cnf

Find the line that looks like so:

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

Comment above line out and restart mysql server

mysql.server restart

Error gone!

Please remove . from your target it should be a id

<a href="#bannerformmodal" data-toggle="modal" data-target="#bannerformmodal">Load me</a>

Also you have to give your modal id like below

<div class="modal fade bannerformmodal" tabindex="-1" role="dialog" aria-labelledby="bannerformmodal" aria-hidden="true" id="bannerformmodal">

Here is the solution in a fiddle.

Every RDBMS is a DBMS, but the opposite is not true: RDBMS is a DBMS which is based on the relational model, but not every DBMS must be relational.

However, since RDBMS are most common, sometimes the term DBMS is used to denote a DBMS which is NOT relational. It depends on the context.

As explained by this answer, the exact location of the string pool is not specified and can vary from one JVM implementation to another.

It is interesting to note that until Java 7, the pool was in the permgen space of the heap on hotspot JVM but it has been moved to the main part of the heap since Java 7:

Area: HotSpot
Synopsis: In JDK 7, interned strings are no longer allocated in the permanent generation of the Java heap, but are instead allocated in the main part of the Java heap (known as the young and old generations), along with the other objects created by the application. This change will result in more data residing in the main Java heap, and less data in the permanent generation, and thus may require heap sizes to be adjusted. Most applications will see only relatively small differences in heap usage due to this change, but larger applications that load many classes or make heavy use of the String.intern() method will see more significant differences. RFE: 6962931

And in Java 8 Hotspot, Permanent Generation has been completely removed.

I am facing to this problem so many times till I have 32bit PL/SQL Developer and 64bit Oracle DB or Oracle Client.

The solution is:

1. install a 32bit client.
2. set PLSQL DEV-Tools-Preferencies-Oracle Home to new 32bit client Home
3. set PLSQL DEV-Tools-Preferencies-OCI to new 32 bit home /bin/oci.dll For example: c:\app\admin\product\11.2.0\client_1\BIN\oci.dll
4. Save and restart PLSQL DEV.

Edit or create a TNSNAMES.ORA file in c:\app\admin\product\11.2.0\client_1\NETWORK\admin folder like mentioned above.

Try with TNSPING in console like

C:>tnsping ORCL

If still have problem, set the TNS_ADMIN Enviroment properties value pointing to the folder where the TNSNAMES.ORA located, like: c:\app\admin\product\11.2.0\client_1\network\admin

The expression:

 ($min <= $value) && ($value <= $max)

will be true if $value is between $min and $max, inclusively

See the PHP docs for more on comparison operators

A pretty straight forward solution to print binary:

#include <iostream>
using namespace std;
int main()
{
 int num,arr[64];
 cin>>num;
 int i=0,r;
 while(num!=0)
{
  r = num%2;
  arr[i++] = r;
  num /= 2;
}

for(int j=i-1;j>=0;j--){
 cout<<arr[j];
  }
}

I collected some information on the internet and prepared the script that requires no external tool: See my response here. Hope it's helpful.

let str = "abc"
let substr = str.substringToIndex(str.endIndex.predecessor())  // "ab"

In case it helps anyone I had the same error. It turns out my page had not been scrapped by Facebook in awhile and it was an old error. There was a scrape again button on the page that fixed it.

i just upgraded to react-native 0.18.1 today tough having some peer dependencies issues with 0.19.0-rc pre-release version.

Back to your question, what I did was

1. cd android
2. sudo ./gradlew clean (more information about how clean works here)

then back to the working directory and run react-native run-android

you should restart your npm too after that upgrade.

hope this works for you.

• div is a block element
• span is an inline element.

This means that to use them semantically, divs should be used to wrap sections of a document, while spans should be used to wrap small portions of text, images, etc.

For example:

<div>This a large main division, with <span>a small bit</span> of spanned text!</div>

Note that it is illegal to place a block-level element within an inline element, so:

<div>Some <span>text that <div>I want</div> to mark</span> up</div>

...is illegal.

EDIT: As of HTML5, some block elements can be placed inside of some inline elements. See the MDN reference here for a pretty clear listing. The above is still illegal, as <span> only accepts phrasing content, and <div> is flow content.

You asked for some concrete examples, so is one taken from my bowling website, BowlSK:

<div id="header">_x000D_
  <div id="userbar">_x000D_
    Hi there, <span class="username">Chris Marasti-Georg</span> |_x000D_
    <a href="/edit-profile.html">Profile</a> |_x000D_
    <a href="https://www.bowlsk.com/_ah/logout?...">Sign out</a>_x000D_
  </div>_x000D_
  <h1><a href="/">Bowl<span class="sk">SK</span></a></h1>_x000D_
</div>

Ok, what's going on?

Also note that HTML5 includes a broad new set of elements that define common page structures, such as article, section, nav, etc.

Section 4.4 of the HTML 5 working draft lists them and gives hints as to their usage. HTML5 is still a working spec, so nothing is "final" yet, but it is highly doubtful that any of these elements are going anywhere. There is a javascript hack that you will need to use if you want to style these elements in some older version of IE - You need to create one of each element using document.createElement before any of those elements are specified in your source. There are a bunch of libraries that will take care of this for you - a quick Google search turned up html5shiv.

Do:

con.query('SET GLOBAL connect_timeout=28800')
con.query('SET GLOBAL interactive_timeout=28800')
con.query('SET GLOBAL wait_timeout=28800')

Parameter meaning (taken from MySQL Workbench in Navigator: Instance > Options File > Tab "Networking" > Section "Timeout Settings")

• connect_timeout: Number of seconds the mysqld server waits for a connect packet before responding with 'Bad handshake'
• interactive_timeout Number of seconds the server waits for activity on an interactive connection before closing it
• wait_timeout Number of seconds the server waits for activity on a connection before closing it

BTW: 28800 seconds are 8 hours, so for a 10 hour execution time these values should be actually higher.

The Immediate window is used to debug and evaluate expressions, execute statements, print variable values, and so forth. It allows you to enter expressions to be evaluated or executed by the development language during debugging.

To display Immediate Window, choose Debug >Windows >Immediate or press Ctrl-Alt-I

Here is an example with Immediate Window:

int Sum(int x, int y) { return (x + y);}
void main(){
int a, b, c;
a = 5;
b = 7;
c = Sum(a, b);
char temp = getchar();}

Maven is packaged for Fedora since mid 2014, so it is now pretty easy. Just type

sudo dnf install maven

Now test the installation, just run maven in a random directory

mvn

And it will fail, because you did not specify a goal, e.g. mvn package

You can also, do this.

$(window).on("scroll", function () {
   if ($(this).scrollTop() > 800) {
      #code here
   } else {
      #code here
   }
});

I guess you can use the size attribute. It works in all recent browsers.

MySQL: ERROR 1040: Too many connections

This basically tells that MySQL handles the maximum number of connections simultaneously and by default it handles 100 connections simultaneously.

These following reasons cause MySQL to run out connections.

1. Slow Queries

2. Data Storage Techniques

3. Bad MySQL configuration

I was able to overcome this issues by doing the followings.

Open MySQL command line tool and type,

show variables like "max_connections";

This will return you something like this.

+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 100   |
+-----------------+-------+

You can change the setting to e.g. 200 by issuing the following command without having to restart the MySQL server.

set global max_connections = 200;

Now when you restart MySQL the next time it will use this setting instead of the default.

Keep in mind that increase of the number of connections will increase the amount of RAM required for MySQL to run.

There are many ways to do it, but this is pretty simple and avoids issues with disrupting inline content positioning. You might need to adjust for margins/padding, too.

#backdrop, #curtain {
  height: 100px;
  width: 200px;
}

#curtain {
  position: relative;
  top: -100px;
}

I had a similar issue with Pandas, you need to use the iterrows() function to iterate through a Pandas dataset Pandas documentation for iterrows

data = pd.read_csv('foo.csv')
for index,item in data.iterrows():
    print('{} {}'.format(item["gravatar_id"], item["position"]))

note that you need to handle the index in the dataset that is also returned by the function.

Thanks to @CopsOnRoad, his solution was a big help but only works for SDK 26 and higher. My app targets 24 and higher.

To keep Android Studio from complaining you need a conditional directly around the notification. It is not smart enough to know the code is in a method conditional to VERSION_CODE.O.

@Override
public void onCreate(){
    super.onCreate();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
        startMyOwnForeground();
    else
        startForeground(1, new Notification());
}

private void startMyOwnForeground(){

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){

        String NOTIFICATION_CHANNEL_ID = "com.example.simpleapp";
        String channelName = "My Background Service";
        NotificationChannel chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, channelName, NotificationManager.IMPORTANCE_NONE);
        chan.setLightColor(Color.BLUE);
        chan.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        assert manager != null;
        manager.createNotificationChannel(chan);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
        Notification notification = notificationBuilder.setOngoing(true)
                .setSmallIcon(AppSpecific.SMALL_ICON)
                .setContentTitle("App is running in background")
                .setPriority(NotificationManager.IMPORTANCE_MIN)
                .setCategory(Notification.CATEGORY_SERVICE)
                .build();
        startForeground(2, notification);
    }
}

when initializing dialog builder, pass second parameter as the theme. It will automatically show material design with API level 21.

AlertDialog.Builder builder = new AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_DARK);

or,

AlertDialog.Builder builder = new AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);

FOO=bar
export FOO

I've used next function to get scrollbar height/width:

function getBrowserScrollSize(){

    var css = {
        "border":  "none",
        "height":  "200px",
        "margin":  "0",
        "padding": "0",
        "width":   "200px"
    };

    var inner = $("<div>").css($.extend({}, css));
    var outer = $("<div>").css($.extend({
        "left":       "-1000px",
        "overflow":   "scroll",
        "position":   "absolute",
        "top":        "-1000px"
    }, css)).append(inner).appendTo("body")
    .scrollLeft(1000)
    .scrollTop(1000);

    var scrollSize = {
        "height": (outer.offset().top - inner.offset().top) || 0,
        "width": (outer.offset().left - inner.offset().left) || 0
    };

    outer.remove();
    return scrollSize;
}

This jQuery-based solutions works in IE7+ and all other modern browsers (including mobile devices where scrollbar height/width will be 0).

I know this is an old question, but here is my contribution. Instead of all these tricks, you can just simply wrap a function inside another function. Like I have done here:

<div data-bind="click: function(){ f('hello parameter'); }">Click me once</div>
<div data-bind="click: function(){ f('no no parameter'); }">Click me twice</div>

var VM = function(){
   this.f = function(param){
     console.log(param);
   }
}
ko.applyBindings(new VM());

And here is the fiddle

Eclipse does not have internal Subversion connectivity. After you've downloaded and unzipped Eclipse, you have to install a Subversion plug-in. Check with the other developers as to which Subversion plug-in you're using. Subclipse is one Subversion plug-in.

After you've installed the Subversion plug-in, you have to give Eclipse the repository information in the SVN Repositories view of the SVN Repositories perspective. One of the other developers should have that information.

Finally, you check out the project from Subversion, by left clicking on the Package Explorer, selecting New -> Project, and in the New Project wizard,left clicking on SVN -> Checkout projects from SVN.

If you can't use any libraries to encode the value, http://www.urlencoder.org/ or http://www.urlencode-urldecode.com/ or ...

Just enter your value "M&M", not the full URL ;-)

Be sure to check out verilog-mode and especially verilog-auto. http://www.veripool.org/wiki/verilog-mode/ It is a verilog mode for emacs, but plugins exist for vi(m?) for example.

An instantiation can be automated with AUTOINST. The comment is expanded with M-x verilog-auto and can afterwards be manually edited.

subcomponent subcomponent_instance_name(/*AUTOINST*/);

Expanded

subcomponent subcomponent_instance_name (/*AUTOINST*/
  //Inputs
  .clk,         (clk)           
  .rst_n,       (rst_n)
  .data_rx      (data_rx_1[9:0]),
  //Outputs
  .data_tx      (data_tx[9:0])
);

Implicit wires can be automated with /*AUTOWIRE*/. Check the link for further information.

Have you tried somethig like this?

.showme{display: none;}
.showhim:hover .showme{display : block;}
.hideme{display:block;}
.showhim:hover .hideme{display:none;}

<div class="showhim">HOVER ME
  <div class="showme">hai</div>
  <div class="hideme">bye</div>
</div>

I dont know any reason why it shouldn't be possible.

Okay I just realized the answer is to remove the first float left from the first DIV. Don't know why I didn't see that before.

we have to create your own docker volume mapped with the host directory before we mention in the docker-compose.yml as external

1.Create volume named share

docker volume create --driver local \
--opt type=none \
--opt device=/home/mukundhan/share \
--opt o=bind share

2.Use it in your docker-compose

version: "3"

volumes:
  share:
    external: true

services:
  workstation:
    container_name: "workstation"
    image: "ubuntu"
    stdin_open: true
    tty: true
    volumes:
      - share:/share:consistent
      - ./source:/source:consistent
    working_dir: /source
    ipc: host
    privileged: true
    shm_size: '2gb'
  db:
    container_name: "db"
    image: "ubuntu"
    stdin_open: true
    tty: true
    volumes:
      - share:/share:consistent
    working_dir: /source
    ipc: host

This way we can share the same directory with many services running in different containers

You can use lookups in Ansible in order to get the contents of a file, e.g.

user_data: "{{ lookup('file', user_data_file) }}"

Caveat: This lookup will work with local files, not remote files.

Here's a complete example from the docs:

- hosts: all
  vars:
     contents: "{{ lookup('file', '/etc/foo.txt') }}"
  tasks:
     - debug: msg="the value of foo.txt is {{ contents }}"

whereever you want it to, if you set it your function call: error_log($errorMessageforLog . "\n", 4, 'somePath/SomeFileName.som');

First off, Daniel's answer is the correct, safe option.

For the specific case of changing from SQL_ASCII to something else, you can cheat and simply poke the pg_database catalogue to reassign the database encoding. This assumes you've already stored any non-ASCII characters in the expected encoding (or that you simply haven't used any non-ASCII characters).

Then you can do:

update pg_database set encoding = pg_char_to_encoding('UTF8') where datname = 'thedb'

This will not change the collation of the database, just how the encoded bytes are converted into characters (so now length('£123') will return 4 instead of 5). If the database uses 'C' collation, there should be no change to ordering for ASCII strings. You'll likely need to rebuild any indices containing non-ASCII characters though.

Caveat emptor. Dumping and reloading provides a way to check your database content is actually in the encoding you expect, and this doesn't. And if it turns out you did have some wrongly-encoded data in the database, rescuing is going to be difficult. So if you possibly can, dump and reinitialise.

You need to add:

 #include <cstdlib>

in order for the compiler to see the prototype for system().

I like short version: mvn clean install -DskipTests

It's work too: mvn clean install -DskipTests=true

If you absolutely must, you can also use the maven.test.skip property to skip compiling the tests. maven.test.skip is honored by Surefire, Failsafe and the Compiler Plugin. mvn clean install -Dmaven.test.skip=true

and you can add config in maven.xml

<project>
      [...]
      <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>

systemctl start docker-container-cleanup.timer
systemctl enable docker-image-cleanup.timer

Can anyone tell me why json_encode adds slashes?

Forward slash characters can cause issues (when preceded by a < it triggers the SGML rules for "end of script element") when embedded in an HTML script element. They are escaped as a precaution.

Because when I try do use jQuery.parseJSON(response); in my js script, it returns null. So my guess it has something to do with the slashes.

It doesn't. In JSON "/" and "\/" are equivalent.

The JSON you list in the question is valid (you can test it with jsonlint). Your problem is likely to do with what happens to it between json_encode and parseJSON.

Not putting a submit button could do. Just put a script to the input (type=button) or add eventListener if you want it to submit the data in the form.

Rather use this

<input type="button">

than using this

<input type="submit">
