If you want to update multiple rows using limit in MySQL you can use this construct:

UPDATE table_name SET name='test'
WHERE id IN (
    SELECT id FROM (
        SELECT id FROM table_name 
        ORDER BY id ASC  
        LIMIT 0, 10
    ) tmp
)

in your setChilds, you might want to try looping thru the list and doing something like

child.parent = this;

you also should set up the cascade on the parent to the appropriate values.

Your code is correct. Just put them inside the <VirtualHost *:443>

Example:

<VirtualHost *:443>
  SSLEnable

  RewriteEngine On
  RewriteCond %{HTTPS} on
  RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI}

</VirtualHost>

You cannot call a function that requires arguments in a template. Write a template tag or filter instead.

An other very good documentation tool is sphinx. It will be used for the upcoming python 2.6 documentation and is used by django and a lot of other python projects.

From the sphinx website:

• Output formats: HTML (including Windows HTML Help) and LaTeX, for printable PDF versions
• Extensive cross-references: semantic markup and automatic links for functions, classes, glossary terms and similar pieces of information
• Hierarchical structure: easy definition of a document tree, with automatic links to siblings, parents and children
• Automatic indices: general index as well as a module index
• Code handling: automatic highlighting using the Pygments highlighter
• Extensions: automatic testing of code snippets, inclusion of docstrings from Python modules, and more

Give permission in .htaccess as follows:

<Directory "Your directory path/uploads/">
Allow from all
</Directory>

You can use Collections.frequency:

numbers.stream().filter(i -> Collections.frequency(numbers, i) >1)
                .collect(Collectors.toSet()).forEach(System.out::println);

Easily hit CTRL+SHIFT+T . This will look in the files' names.

Found it, it's:

g/^\s*$/d

Source: Power of g at vim wikia

Brief explanation of :g

:[range]g/pattern/cmd

This acts on the specified [range] (default whole file), by executing the Ex command cmd for each line matching pattern (an Ex command is one starting with a colon such as :d for delete). Before executing cmd, "." is set to the current line.

Now with new ng-bootstrap 1.0.0-beta.5 version supports most of the native Angular directives based on Bootstrap's markup and CSS.

The only dependency required to work with this is bootstrap. No Need to use jquery and popper.js dependencies.

ng-bootstrap is to completely replaced JavaScript implementation for components. So you don't need to include bootstrap.min.js in the scripts section in your .angular-cli.json.

follow these steps when you are integrating bootstrap with generated project with angular-cli latest version.

• Inculde bootstrap.min.css in your .angular-cli.json, styles section.

  "styles": [
     "styles.scss",
     "../node_modules/bootstrap/dist/css/bootstrap.min.css"
  ],
  

• Install ng-bootstrap dependency.

  npm install --save @ng-bootstrap/ng-bootstrap
  

• Add this to your main module class.

  import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
  

• Include the following in your main module imports section.

  @NgModule({
     imports: [NgbModule.forRoot(), ...],
  })
  

• Do the following also in your sub module(s) if you are going to use ng-bootstrap components inside those module classes.

  import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
  
  @NgModule({
     imports: [NgbModule, ...],
  })
  

• Now your project is ready to use available ng-bootstrap components.

Here is a function to compute the weighted r-squared with Python and Numpy (most of the code comes from sklearn):

from __future__ import division 
import numpy as np

def compute_r2_weighted(y_true, y_pred, weight):
    sse = (weight * (y_true - y_pred) ** 2).sum(axis=0, dtype=np.float64)
    tse = (weight * (y_true - np.average(
        y_true, axis=0, weights=weight)) ** 2).sum(axis=0, dtype=np.float64)
    r2_score = 1 - (sse / tse)
    return r2_score, sse, tse

Example:

from __future__ import print_function, division 
import sklearn.metrics 

def compute_r2_weighted(y_true, y_pred, weight):
    sse = (weight * (y_true - y_pred) ** 2).sum(axis=0, dtype=np.float64)
    tse = (weight * (y_true - np.average(
        y_true, axis=0, weights=weight)) ** 2).sum(axis=0, dtype=np.float64)
    r2_score = 1 - (sse / tse)
    return r2_score, sse, tse    

def compute_r2(y_true, y_predicted):
    sse = sum((y_true - y_predicted)**2)
    tse = (len(y_true) - 1) * np.var(y_true, ddof=1)
    r2_score = 1 - (sse / tse)
    return r2_score, sse, tse

def main():
    '''
    Demonstrate the use of compute_r2_weighted() and checks the results against sklearn
    '''        
    y_true = [3, -0.5, 2, 7]
    y_pred = [2.5, 0.0, 2, 8]
    weight = [1, 5, 1, 2]
    r2_score = sklearn.metrics.r2_score(y_true, y_pred)
    print('r2_score: {0}'.format(r2_score))  
    r2_score,_,_ = compute_r2(np.array(y_true), np.array(y_pred))
    print('r2_score: {0}'.format(r2_score))
    r2_score = sklearn.metrics.r2_score(y_true, y_pred,weight)
    print('r2_score weighted: {0}'.format(r2_score))
    r2_score,_,_ = compute_r2_weighted(np.array(y_true), np.array(y_pred), np.array(weight))
    print('r2_score weighted: {0}'.format(r2_score))

if __name__ == "__main__":
    main()
    #cProfile.run('main()') # if you want to do some profiling

outputs:

r2_score: 0.9486081370449679
r2_score: 0.9486081370449679
r2_score weighted: 0.9573170731707317
r2_score weighted: 0.9573170731707317

This corresponds to the formula (mirror):

with f_i is the predicted value from the fit, y_{av} is the mean of the observed data y_i is the observed data value. w_i is the weighting applied to each data point, usually w_i=1. SSE is the sum of squares due to error and SST is the total sum of squares.

If interested, the code in R: https://gist.github.com/dhimmel/588d64a73fa4fef02c8f (mirror)

var str = "This-is-a-news-item-";
while (str.contains("-")) {
  str = str.replace("-", ' ');
}
alert(str);

I found that one use of str.replace() would only replace the first hyphen, so I looped thru while the input string still contained any hyphens, and replaced them all.

"^.*$"

literally just means select everything

"^"  // anchors to the beginning of the line
".*" // zero or more of any character
"$"  // anchors to end of line

You will want to look into the nl2br() function along with the trim().

The nl2br() will insert <br /> before the newline character (\n) and the trim() will remove any ending \n or whitespace characters.

$text = trim($_POST['textareaname']); // remove the last \n or whitespace character
$text = nl2br($text); // insert <br /> before \n 

That should do what you want.

UPDATE

The reason the following code will not work is because in order for \n to be recognized, it needs to be inside double quotes since double quotes parse data inside of them, where as single quotes takes it literally, IE "\n"

$text = str_replace('\n', '<br />', $text);

To fix it, it would be:

$text = str_replace("\n", '<br />', $text);

But it is still better to use the builtin nl2br() function, PHP provides.

EDIT

Sorry, I figured the first question was so you could add the linebreaks in, indeed this will change the answer quite a bit, as anytype of explode() will remove the line breaks, but here it is:

$text = trim($_POST['textareaname']);
$textAr = explode("\n", $text);
$textAr = array_filter($textAr, 'trim'); // remove any extra \r characters left behind

foreach ($textAr as $line) {
    // processing here. 
} 

If you do it this way, you will need to append the <br /> onto the end of the line before the processing is done on your own, as the explode() function will remove the \n characters.

Added the array_filter() to trim() off any extra \r characters that may have been lingering.

If Rizowski's answer of clicking the green plug connect-button doesn't work and you have multiple workspaces, the problem might go away by switching to the other workspace and back again.

As others have mentioned, Google uses a homegrown solution called BigTable and they've released a few papers describing it out into the real world.

The Apache folks have an implementation of the ideas presented in these papers called HBase. HBase is part of the larger Hadoop project which according to their site "is a software platform that lets one easily write and run applications that process vast amounts of data." Some of the benchmarks are quite impressive. Their site is at http://hadoop.apache.org.

In my case, this error happened because my HTML had a trailing linebreak.

var myHtml = '<p>\
    This should work.\
    But does not.\
</p>\
';

jQuery('.something').append(myHtml); // this causes the error

To avoid the error, you just need to trim the HTML.

jQuery('.something').append(jQuery.trim(myHtml)); // this works

It works like a charm someone can try this. Here I have used soft delete checker. You could omit the last: id,deleted_at, NULL if your model doesn't have soft delete implementation.

public function rules()
{
    switch ($this->method()) {
        case 'PUT':
            $emailRules = "required|unique:users,email,{$this->id},id,deleted_at,NULL";
            break;
        default:
            $emailRules = "required|unique:users,email,NULL,id,deleted_at,NULL";
            break;
    }

    return [
        'email' => $emailRules,
        'display_name' => 'nullable',
        'description' => 'nullable',
    ];
}

Thank you.

For the total uploaded there doesn't seem to be a way to handle that, but there's something similar to what you want for download. Once readyState is 3, you can periodically query responseText to get all the content downloaded so far as a String (this doesn't work in IE), up until all of it is available at which point it will transition to readyState 4. The total bytes downloaded at any given time will be equal to the total bytes in the string stored in responseText.

For a all or nothing approach to the upload question, since you have to pass a string for upload (and it's possible to determine the total bytes of that) the total bytes sent for readyState 0 and 1 will be 0, and the total for readyState 2 will be the total bytes in the string you passed in. The total bytes both sent and received in readyState 3 and 4 will be the sum of the bytes in the original string plus the total bytes in responseText.

Goto View -> Show Symbol -> Show All Characters. Uncheck it. There you go.!!

I want to change or update my ContactNo to 8018070999 where there is 8018070777 using Case statement

Some handy quick functions (if you're not using Boost):

template<typename T>
std::string ToString(const T& v)
{
    std::ostringstream ss;
    ss << v;
    return ss.str();
}

template<typename T>
T FromString(const std::string& str)
{
    std::istringstream ss(str);
    T ret;
    ss >> ret;
    return ret;
}

Example:

int i = FromString<int>(s);
std::string str = ToString(i);

Works for any streamable types (floats etc). You'll need to #include <sstream> and possibly also #include <string>.

If you are using WAMP...

you should add or uncomment the property always_populate_raw_post_data in php.ini and set its value to -1. In my case php.ini is located in:

C:\wamp64\bin\php\php5.6.25\php.ini

..but if you are still getting the warning (as I was)

You should also set always_populate_raw_post_data = -1 in phpForApache.ini:

C:\wamp64\bin\php\php5.6.25\phpForApache.ini

If you can't find this file, open a browser window and go to:

http://localhost/?phpinfo=1

and look for the value of Loaded Configuration File key. In my case the php.ini used by WAMP is located in:

C:\wamp64\bin\apache\apache2.4.23\bin\php.ini (symlink to C:\wamp64\bin\php\php5.6.25\phpForApache.ini)

Finally restart WAMP (or click restart all services)

I guess it's a matter of taste, although (mistakenly) mixing them up might cause some undesired behaviors:

true && false || false; // returns false

true and false || false; // returns true

Hence, using && and || is safer for they have the highest precedence. In what regards to readability, I'd say these operators are universal enough.

UPDATE: About the comments saying that both operations return false ... well, in fact the code above does not return anything, I'm sorry for the ambiguity. To clarify: the behavior in the second case depends on how the result of the operation is used. Observe how the precedence of operators comes into play here:

var_dump(true and false || false); // bool(false)

$a = true and false || false; var_dump($a); // bool(true)

The reason why $a === true is because the assignment operator has precedence over any logical operator, as already very well explained in other answers.

According to the HTML standard, the content model of the HTML element is:

A head element followed by a body element.

You can either define the BODY element in the source code:

<html>
    <body>
        ... web-page ...
    </body>
</html>

or you can omit the BODY element:

<html>
    ... web-page ...
</html>

However, it is invalid to place the BODY element inside the web-page content (in-between other elements or text content), like so:

<html>
    ... content ...
    <body>
        ... content ...
    </body>
    ... content ...
</html>

Below code is using com.google.gson.JsonArray. I have printed the number of element in list as well as the elements in List

import java.util.ArrayList;

            //jsonArr.
            Gson googleJson = new Gson();
            ArrayList jsonObjList = googleJson.fromJson(jsonArr, ArrayList.class);
            System.out.println("List size is : "+jsonObjList.size());
                    System.out.println("List Elements are  : "+jsonObjList.toString());

OUTPUT

List size is : 4

List Elements are  : [8.8.8.8, 8.8.4.4, 156.154.70.1, 156.154.71.1]

Be careful with findOne and remove!

  User.findOne({name: 'Alice'}).remove().exec();

The code above removes ALL users named 'Alice' instead of the first one only.

By the way, I prefer to remove documents like this:

  User.remove({...}).exec();

Or provide a callback and omit the exec()

  User.remove({...}, callback);

What

It is possible with EditorConfig.

EditorConfig helps developers define and maintain consistent coding styles between different editors and IDEs.

This also includes file encoding.

EditorConfig is built-in Visual Studio 2017 by default, and I there were plugins available for versions as old as VS2012. Read more from EditorConfig Visual Studio Plugin page.

How

You can set up a EditorConfig configuration file high enough in your folder structure to span all your intended repos (up to your drive root should your files be really scattered everywhere) and configure the setting charset:

charset: set to latin1, utf-8, utf-8-bom, utf-16be or utf-16le to control the character set.

You can add filters and exceptions etc on every folder level or by file name/type should you wish for finer control.

Once configured then compatible IDEs should automatically do it's thing to make matching files comform to set rules. Note that Visual Studio does not automatically convert all your files but do its bit when you work with files in IDE (open and save).

What next

While you could have a Visual-studio-wide setup, I strongly suggest to still include an EditorConfig root to your solution version control, so that explicit settings are automatically synced to all team members as well. Your drive root editorconfig file can be the fallback should some project not have their own editorconfig files set up yet.

I tend to use yield-return when I calculate the next item in the list (or even the next group of items).

Using your Version 2, you must have the complete list before returning. By using yield-return, you really only need to have the next item before returning.

Among other things, this helps spread the computational cost of complex calculations over a larger time-frame. For example, if the list is hooked up to a GUI and the user never goes to the last page, you never calculate the final items in the list.

Another case where yield-return is preferable is if the IEnumerable represents an infinite set. Consider the list of Prime Numbers, or an infinite list of random numbers. You can never return the full IEnumerable at once, so you use yield-return to return the list incrementally.

In your particular example, you have the full list of products, so I'd use Version 2.

awk

awk '{gsub(/two.*/,"")}1' file

Ruby

ruby -ne 'print $_.gsub(/two.*/,"")' file

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

If you want to execute a function when something is done. One of a good solution is to listen to events. For example, I'll implement a Dispatcher, a DispatcherEvent class with ES6,then:

let Notification = new Dispatcher()
Notification.on('Load data success', loadSuccessCallback)

const loadSuccessCallback = (data) =>{
   ...
}
//trigger a event whenever you got data by
Notification.dispatch('Load data success')

Dispatcher:

class Dispatcher{
  constructor(){
    this.events = {}
  }

  dispatch(eventName, data){
    const event = this.events[eventName]
    if(event){
      event.fire(data)
    }
  }

  //start listen event
  on(eventName, callback){
    let event = this.events[eventName]
    if(!event){
      event = new DispatcherEvent(eventName)
      this.events[eventName] = event
    }
    event.registerCallback(callback)
  }

  //stop listen event
  off(eventName, callback){
    const event = this.events[eventName]
    if(event){
      delete this.events[eventName]
    }
  }
}

DispatcherEvent:

class DispatcherEvent{
  constructor(eventName){
    this.eventName = eventName
    this.callbacks = []
  }

  registerCallback(callback){
    this.callbacks.push(callback)
  }

  fire(data){
    this.callbacks.forEach((callback=>{
      callback(data)
    }))
  }
}

Happy coding!

p/s: My code is missing handle some error exceptions

You can't transition between two background images, as there's no way for the browser to know what you want to interpolate. As you've discovered, you can transition the background position. If you want the image to fade in on mouse over, I think the best way to do it with CSS transitions is to put the image on a containing element and then animate the background colour to transparent on the link itself:

span {
    background: url(button.png) no-repeat 0 0;
}
a {
    width: 32px;
    height: 32px;
    text-align: left;
    background: rgb(255,255,255);

    -webkit-transition: background 300ms ease-in 200ms; /* property duration timing-function delay */
    -moz-transition: background 300ms ease-in 200ms;
    -o-transition: background 300ms ease-in 200ms;
    transition: background 300ms ease-in 200ms;
    }
a:hover {
    background: rgba(255,255,255,0);
}

JSON.parse has two parameters. The second parameter, reviver, is a transform function that can be formatted output format we want. See ECMA specification here.

In reviver function:

• if we return undefined, the original property will be deleted.
• this is the object containing the property being processed as this function, and the property name as a string, the property value as arguments of this function.

const json = '[{"_id":"5078c3a803ff4197dc81fbfb","email":"[email protected]","image":"some_image_url","name":"Name 1"},{"_id":"5078c3a803ff4197dc81fbfc","email":"[email protected]","image":"some_image_url","name":"Name 2"}]';

const obj = JSON.parse(json, function(k, v) {
    if (k === "_id") {
        this.id = v;
        return; # if return  undefined, orignal property will be removed
    }
    return v;
});

const res = JSON.stringify(obj);
console.log(res)

output:

Imagine a <span> element inside a <div>. If you give the <span> element a height of 100px and a red border for example, it will look like this with

display: inline

display: inline-block

display: block

Code: http://jsfiddle.net/Mta2b/

Elements with display:inline-block are like display:inline elements, but they can have a width and a height. That means that you can use an inline-block element as a block while flowing it within text or other elements.

Difference of supported styles as summary:

• inline: only margin-left, margin-right, padding-left, padding-right
• inline-block: margin, padding, height, width

Restartable mode (/Z) has to do with a partially-copied file. With this option, should the copy be interrupted while any particular file is partially copied, the next execution of robocopy can pick up where it left off rather than re-copying the entire file.

That option could be useful when copying very large files over a potentially unstable connection.

Backup mode (/B) has to do with how robocopy reads files from the source system. It allows the copying of files on which you might otherwise get an access denied error on either the file itself or while trying to copy the file's attributes/permissions. You do need to be running in an Administrator context or otherwise have backup rights to use this flag.

#!/usr/bin/perl

$sub = "\\1";
$str = "hi1234";
$res = $str;
$match = "hi(.*)";
$res =~ s/$match/$1/g;

print $res

This got me the '1234'.

This doesn't work - it hides the .myDIV when you click inside of it.

$('.openDiv').click(function(e) {
$('.myDiv').show(); 
e.stopPropagation();
})

$(document).click(function(){  
$('.myDiv').hide(); 

});

});

<a class="openDiv">DISPLAY DIV</a>

<div class="myDiv">HIDE DIV</div>

Use:

>>> import datetime
>>> datetime.datetime.now()
datetime.datetime(2009, 1, 6, 15, 8, 24, 78915)

>>> print(datetime.datetime.now())
2009-01-06 15:08:24.789150

And just the time:

>>> datetime.datetime.now().time()
datetime.time(15, 8, 24, 78915)

>>> print(datetime.datetime.now().time())
15:08:24.789150

See the documentation for more information.

To save typing, you can import the datetime object from the datetime module:

>>> from datetime import datetime

Then remove the leading datetime. from all of the above.

Remote Procedure Call (RPC) is a inter process communication which allows calling a function in another process residing in local or remote machine.

Remote method invocation (RMI) is an API, which implements RPC in java with support of object oriented paradigms.

1. You can think of invoking RPC is like calling a C procedure. RPC supports primitive data types where as RMI support method parameters/return types as java objects.

2. RMI is easy to program unlike RPC. You can think your business logic in terms of objects instead of a sequence of primitive data types.

3. RPC is language neutral unlike RMI, which is limited to java

4. RMI is little bit slower to RPC

Have a look at this article for RPC implementation in C

In node.js we can use node-geocoder npm module to get address from lat, lng.,

geo.js

var NodeGeocoder = require('node-geocoder');

var options = {
  provider: 'google',
  httpAdapter: 'https', // Default
  apiKey: ' ', // for Mapquest, OpenCage, Google Premier
  formatter: 'json' // 'gpx', 'string', ...
};

var geocoder = NodeGeocoder(options);

geocoder.reverse({lat:28.5967439, lon:77.3285038}, function(err, res) {
  console.log(res);
});

output:

node geo.js

[ { formattedAddress: 'C-85B, C Block, Sector 8, Noida, Uttar Pradesh 201301, India',
    latitude: 28.5967439,

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

sudo chmod +x filename.jar

Try this, I hope this works.

You can also use prompter.

Shamelessly taken from the README:

#pip install prompter

from prompter import yesno

>>> yesno('Really?')
Really? [Y/n]
True

>>> yesno('Really?')
Really? [Y/n] no
False

>>> yesno('Really?', default='no')
Really? [y/N]
True

Union is not what you want. You want to use joins to create single rows. It's a little unclear what constitutes a unique row in your tables and how they really relate to each other and it's also unclear if one table will have rows for every country in every year. But I think this will work:

CREATE VIEW V AS (

  SELECT i.country,i.year,p.pop,f.food,i.income FROM
    INCOME i
  LEFT JOIN 
    POP p 
  ON
    i.country=p.country
  LEFT JOIN
    Food f
  ON 
    i.country=f.country
  WHERE 
    i.year=p.year
  AND
    i.year=f.year
);

The left (outer) join will return rows from the first table even if there are no matches in the second. I've written this assuming you would have a row for every country for every year in the income table. If you don't things get a bit hairy as MySQL does not have built in support for FULL OUTER JOINs last I checked. There are ways to simulate it, and they would involve unions. This article goes into some depth on the subject: http://www.xaprb.com/blog/2006/05/26/how-to-write-full-outer-join-in-mysql/

Like a lot of functions, this one can be used in many different ways to solve many different problems, I think of it as yet another tool in our toolbelts.

So far, the discussion has focused heavily on simply hiding an ID, but that is only one value, why not use it for lots of values! That is what I am doing, I use it to load up the values in a class only one view at a time, because html.beginform creates a new object and if your model object for that view already had some values passed to it, those values will be lost unless you provide a reference to those values in the beginform.

To see a great motivation for the html.hiddenfor, I recommend you see Passing data from a View to a Controller in .NET MVC - "@model" not highlighting

Instead of

css=#container

use

css=div.container:nth-of-type(1),css=div.container:nth-of-type(2)

You could do something like this also:

ol {
  font-weight: bold;
}

ol > li > * {
  font-weight: normal;
}

So you have no "style" attributes in your HTML

Yes, == is bad for comparing Strings (any objects really, unless you know they're canonical). == just compares object references. .equals() tests for equality. For Strings, often they'll be the same but as you've discovered, that's not guaranteed always.

For me:

<input id="color" value="Blue"/>

This can be fetched by below snippet.

page = requests.get("https://www.abcd.com")
soup = BeautifulSoup(page.content, 'html.parser')
colorName = soup.find(id='color')
print(color['value'])

If you are doing something nobody here will listen you about because "you're doing it the wrong way", but you have to do it "the wrong way" for reasons too asinine to explain and also beyond your ability to control, you can try this:

Get libffi and install it into your user install area the usual way.

git clone https://github.com/libffi/libffi.git
cd libffi
./configure --prefix=path/to/your/install/root
make
make install

Then go back to your Python 3 source and find this part of the code in setup.py at the top level of the python source directory

        ffi_inc = [sysconfig.get_config_var("LIBFFI_INCLUDEDIR")]
        if not ffi_inc or ffi_inc[0] == '':
            ffi_inc = find_file('ffi.h', [], inc_dirs)
        if ffi_inc is not None:
            ffi_h = ffi_inc[0] + '/ffi.h'
            if not os.path.exists(ffi_h):
                ffi_inc = None
                print('Header file {} does not exist'.format(ffi_h))
        ffi_lib = None
        if ffi_inc is not None:
            for lib_name in ('ffi', 'ffi_pic'):
                if (self.compiler.find_library_file(lib_dirs, lib_name)):
                    ffi_lib = lib_name
                    break

        ffi_lib="ffi"  # --- AND INSERT THIS LINE HERE THAT DOES NOT APPEAR ---
        if ffi_inc and ffi_lib:
            ext.include_dirs.extend(ffi_inc)
            ext.libraries.append(ffi_lib)
            self.use_system_libffi = True

and add the line I have marked above with the comment. Why it is necessary, and why there is no way to get configure to respect '--without-system-ffi` on Linux platforms, perhaps I will find out why that is "unsupported" in the next couple of hours, but everything has worked ever since. Otherwise, best of luck... YMMV.

WHAT IT DOES: just overrides the logic there and causes the compiler linking command to add "-lffi" which is all that it really needs. If you have the library user-installed, it is probably detecting the headers fine as long as your PKG_CONFIG_PATH includes path/to/your/install/root/lib/pkgconfig.

open div then put

style="width:100% ; margin:0px auto;" 

image tag (or) content

close div

update @tymeJV 's answer eg:

 <div style="display: none">
    <input type="text" name='price' ng-model="price" ng-init="price = <%= @product.price.to_s %>" >
 </div>

Paste the below code in the ActionResult of your controller and place the debugger at this point.

var errors = ModelState
    .Where(x => x.Value.Errors.Count > 0)
    .Select(x => new { x.Key, x.Value.Errors })
    .ToArray();

The difference is:
- orphanRemoval = true: "Child" entity is removed when it's no longer referenced (its parent may not be removed).
- CascadeType.REMOVE: "Child" entity is removed only when its "Parent" is removed.

It is good to understand with a Venn diagramm.

here is the link to the source. There is a good description.

var Foo = function(){
    document.getElementById( "a" ).setAttribute( "onClick", "javascript: Boo();" );
}

var Boo = function(){
    alert("test");
}

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

data

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
 year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
 "Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
 "7.12", "12.99", "10.99", "NA",FALSE)))

This is the behavior of ln if the second arg is a directory. It places a link to the first arg inside it. If you want /etc/nginx to be the symlink, you should remove that directory first and run that same command.

Method1:

Inline elements do not use any width or height you specify. To avoid two div and use like this:

 <div id="container">
<img src="tree.png"  align="left"/>
<h1> A very long text(about 300 words) </h1>
</div>
    <style>
            img {
                display: inline;
                width: 100px;
                height: 100px;
            }
            h1 {
                display: inline;
            }
        </style>

Method2:

Change your CSS as follows

.container div {
    display: inline-block;
    }

Method3:

It is the simple method set width Try the following css:

.container div {
overflow:hidden;
position:relative;
width:90%;
margin-bottom:20px;
margin-top:20px;
margin-left:auto;
margin-right:auto;
}
.image {
width:70%;
display: inline-block;
float: left;
}
.texts { 
height: auto;
width: 30%;
display: inline;
}

You can also stringify the object and then again parse to make the normal object. For example like:-

const obj = JSON.parse(JSON.stringify(mongoObj))

Options>Advanced>connections

Uncheck the option :

Use port 80 and 443 as alternative....

I prefer to use BINARY(32) since it's the optimized way!

You can place in that 32 hex digits from (00 to FF).

Therefore BINARY(32)!

Active directory is a directory service provider, where you can add new user to a directory, remove or modify, specify privilages, assign policy etc. Its just like a phone directory where every person have a unique contact number. Every thing in AD(Active Directory) are considered as Objects and every object is given a Unique ID.(similar to a unique contact number in a phone directory.

Ldap is a protocol specially designed for directory service providers. Windows server OS uses AD as a directory server, AIX which is a UNIX version by IBM uses Tivoli directory server. Both of them uses LDAP protocol for interacting with directory.

Apart from protocol there are LDAP servers, LDAP browsers too.

Here you go. This solution uses a DataInputStream to scan for the position of the string you want replaced and uses a FileChannel to replace the text at that exact position. It only replaces the first occurrence of the string that it finds. This solution doesn't store a copy of the entire file somewhere, (either the RAM or a temp file), it just edits the portion of the file that it finds.

public static long scanForString(String text, File file) throws IOException {
    if (text.isEmpty())
        return file.exists() ? 0 : -1;
    // First of all, get a byte array off of this string:
    byte[] bytes = text.getBytes(/* StandardCharsets.your_charset */);

    // Next, search the file for the byte array.
    try (DataInputStream dis = new DataInputStream(new FileInputStream(file))) {

        List<Integer> matches = new LinkedList<>();

        for (long pos = 0; pos < file.length(); pos++) {
            byte bite = dis.readByte();

            for (int i = 0; i < matches.size(); i++) {
                Integer m = matches.get(i);
                if (bytes[m] != bite)
                    matches.remove(i--);
                else if (++m == bytes.length)
                    return pos - m + 1;
                else
                    matches.set(i, m);
            }

            if (bytes[0] == bite)
                matches.add(1);
        }
    }
    return -1;
}

public static void replaceText(String text, String replacement, File file) throws IOException {
    // Open a FileChannel with writing ability. You don't really need the read
    // ability for this specific case, but there it is in case you need it for
    // something else.
    try (FileChannel channel = FileChannel.open(file.toPath(), StandardOpenOption.WRITE, StandardOpenOption.READ)) {
        long scanForString = scanForString(text, file);
        if (scanForString == -1) {
            System.out.println("String not found.");
            return;
        }
        channel.position(scanForString);
        channel.write(ByteBuffer.wrap(replacement.getBytes(/* StandardCharsets.your_charset */)));
    }
}

Input: ABCDEFGHIJKLMNOPQRSTUVWXYZ

Method Call:

replaceText("QRS", "000", new File("path/to/file");

Resulting File: ABCDEFGHIJKLMNOP000TUVWXYZ

Since mobile doesn't give hover feedback, I want, as a user, to see instant feedback when a link is tapped. I noticed that -webkit-tap-highlight-color is the fastest to respond (subjective).

Add the following to your body and your links will have a tap effect.

body {
    -webkit-tap-highlight-color: #ccc;
}

<button type="reset">Reset</reset>

Simplest way I can think off that is robust. Place within the form tag.

You can use getFragmentManager().popBackStack() in basic Fragment to go back.

I resolved this by clearing App Data.

Cypress documentation admits that App Data can get corrupted:

Cypress maintains some local application data in order to save user preferences and more quickly start up. Sometimes this data can become corrupted. You may fix an issue you have by clearing this app data.

1. Open Cypress via cypress open
2. Go to File -> View App Data
3. This will take you to the directory in your file system where your App Data is stored. If you cannot open Cypress, search your file system for a directory named cy whose content should look something like this:

       production
            all.log
            browsers
            bundles
            cache
            projects
            proxy
            state.json

4. Delete everything in the cy folder
5. Close Cypress and open it up again

Use the following CSS codes...

text-decoration:underline;
text-decoration-style: dotted;

Several good solutions here. If you're still on Win2K and can't install anything on the remote computer, this also works:

Open the Computer Management Console (right click My Computer, choose Manage; open from Administrative Tools in the Start Menu; or open from the MMC using the snap-in).

Right click on your computer name and choose "Connect to Remote Computer"

Put in the computer name and credentials and you have full access to many admin functions including the services control panel.

Credit: Can I change the color of Font Awesome's icon color?

(this answer builds on that answer)

(for the bookmark icon, for example:)

inyour.css file:

.icon-bookmark.icon-white {
    color: white;
}

inyour.html file:

<div class="icon-bookmark icon-white"></div>

The easy way to fix this is to add this to your form.

{{ csrf_field() }}
<input type="hidden" name="_method" value="PUT">

then the update method will be like this :

public function update(Request $request, $id)
{
    $project = Project::findOrFail($id);
    $project->name = $request->name;
    $project->description = $request->description;

    $post->save();
}

y-combinator in JavaScript:

var Y = function(f) {
  return (function(g) {
    return g(g);
  })(function(h) {
    return function() {
      return f(h(h)).apply(null, arguments);
    };
  });
};

var factorial = Y(function(recurse) {
  return function(x) {
    return x == 0 ? 1 : x * recurse(x-1);
  };
});

factorial(5)  // -> 120

Edit: I learn a lot from looking at code, but this one is a bit tough to swallow without some background - sorry about that. With some general knowledge presented by other answers, you can begin to pick apart what is happening.

The Y function is the "y-combinator". Now take a look at the var factorial line where Y is used. Notice you pass a function to it that has a parameter (in this example, recurse) that is also used later on in the inner function. The parameter name basically becomes the name of the inner function allowing it to perform a recursive call (since it uses recurse() in it's definition.) The y-combinator performs the magic of associating the otherwise anonymous inner function with the parameter name of the function passed to Y.

For the full explanation of how Y does the magic, checked out the linked article (not by me btw.)

I had a case where I had to fetch the first result of a very big Cartesian product. And it would take ages despite I only wanted one item. The problem was that it had to iterate through many unwanted results before finding a correct one because of the order of the results. So if I had 10 lists of 50 elements and the first element of the two first lists were incompatible, it had to iterate through the Cartesian product of the last 8 lists despite that they would all get rejected.

This implementation enables to test a result before it includes one item from each list. So when I check that an element is incompatible with the already included elements from the previous lists, I immediately go to the next element of the current list rather than iterating through all products of the following lists.

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

You need to first change the constraint and then animate the update.
This should be in the superview.

self.nameInputConstraint.constant = 8

Swift 2

UIView.animateWithDuration(0.5) {
    self.view.layoutIfNeeded()
}

Swift 3, 4, 5

UIView.animate(withDuration: 0.5) {
    self.view.layoutIfNeeded()
}

write following statement in your app's build.gradle file.

com.android.support:appcompat-v7:18.0.+

That's it

I developed a 2048 AI using expectimax optimization, instead of the minimax search used by @ovolve's algorithm. The AI simply performs maximization over all possible moves, followed by expectation over all possible tile spawns (weighted by the probability of the tiles, i.e. 10% for a 4 and 90% for a 2). As far as I'm aware, it is not possible to prune expectimax optimization (except to remove branches that are exceedingly unlikely), and so the algorithm used is a carefully optimized brute force search.

Performance

The AI in its default configuration (max search depth of 8) takes anywhere from 10ms to 200ms to execute a move, depending on the complexity of the board position. In testing, the AI achieves an average move rate of 5-10 moves per second over the course of an entire game. If the search depth is limited to 6 moves, the AI can easily execute 20+ moves per second, which makes for some interesting watching.

To assess the score performance of the AI, I ran the AI 100 times (connected to the browser game via remote control). For each tile, here are the proportions of games in which that tile was achieved at least once:

2048: 100%
4096: 100%
8192: 100%
16384: 94%
32768: 36%

The minimum score over all runs was 124024; the maximum score achieved was 794076. The median score is 387222. The AI never failed to obtain the 2048 tile (so it never lost the game even once in 100 games); in fact, it achieved the 8192 tile at least once in every run!

Here's the screenshot of the best run:

This game took 27830 moves over 96 minutes, or an average of 4.8 moves per second.

Implementation

My approach encodes the entire board (16 entries) as a single 64-bit integer (where tiles are the nybbles, i.e. 4-bit chunks). On a 64-bit machine, this enables the entire board to be passed around in a single machine register.

Bit shift operations are used to extract individual rows and columns. A single row or column is a 16-bit quantity, so a table of size 65536 can encode transformations which operate on a single row or column. For example, moves are implemented as 4 lookups into a precomputed "move effect table" which describes how each move affects a single row or column (for example, the "move right" table contains the entry "1122 -> 0023" describing how the row [2,2,4,4] becomes the row [0,0,4,8] when moved to the right).

Scoring is also done using table lookup. The tables contain heuristic scores computed on all possible rows/columns, and the resultant score for a board is simply the sum of the table values across each row and column.

This board representation, along with the table lookup approach for movement and scoring, allows the AI to search a huge number of game states in a short period of time (over 10,000,000 game states per second on one core of my mid-2011 laptop).

The expectimax search itself is coded as a recursive search which alternates between "expectation" steps (testing all possible tile spawn locations and values, and weighting their optimized scores by the probability of each possibility), and "maximization" steps (testing all possible moves and selecting the one with the best score). The tree search terminates when it sees a previously-seen position (using a transposition table), when it reaches a predefined depth limit, or when it reaches a board state that is highly unlikely (e.g. it was reached by getting 6 "4" tiles in a row from the starting position). The typical search depth is 4-8 moves.

Heuristics

Several heuristics are used to direct the optimization algorithm towards favorable positions. The precise choice of heuristic has a huge effect on the performance of the algorithm. The various heuristics are weighted and combined into a positional score, which determines how "good" a given board position is. The optimization search will then aim to maximize the average score of all possible board positions. The actual score, as shown by the game, is not used to calculate the board score, since it is too heavily weighted in favor of merging tiles (when delayed merging could produce a large benefit).

Initially, I used two very simple heuristics, granting "bonuses" for open squares and for having large values on the edge. These heuristics performed pretty well, frequently achieving 16384 but never getting to 32768.

Petr Morávek (@xificurk) took my AI and added two new heuristics. The first heuristic was a penalty for having non-monotonic rows and columns which increased as the ranks increased, ensuring that non-monotonic rows of small numbers would not strongly affect the score, but non-monotonic rows of large numbers hurt the score substantially. The second heuristic counted the number of potential merges (adjacent equal values) in addition to open spaces. These two heuristics served to push the algorithm towards monotonic boards (which are easier to merge), and towards board positions with lots of merges (encouraging it to align merges where possible for greater effect).

Furthermore, Petr also optimized the heuristic weights using a "meta-optimization" strategy (using an algorithm called CMA-ES), where the weights themselves were adjusted to obtain the highest possible average score.

The effect of these changes are extremely significant. The algorithm went from achieving the 16384 tile around 13% of the time to achieving it over 90% of the time, and the algorithm began to achieve 32768 over 1/3 of the time (whereas the old heuristics never once produced a 32768 tile).

I believe there's still room for improvement on the heuristics. This algorithm definitely isn't yet "optimal", but I feel like it's getting pretty close.

That the AI achieves the 32768 tile in over a third of its games is a huge milestone; I will be surprised to hear if any human players have achieved 32768 on the official game (i.e. without using tools like savestates or undo). I think the 65536 tile is within reach!

You can try the AI for yourself. The code is available at https://github.com/nneonneo/2048-ai.

You can also use array_keys() . Newbie friendly:

$keys = array_keys($arrayToWalk);
$arraySize = count($arrayToWalk); 

for($i=0; $i < $arraySize; $i++) {
    echo '<option value="' . $keys[$i] . '">' . $arrayToWalk[$keys[$i]] . '</option>';
}

My guess is that $_.Name does not exist.

If I were you, I'd bring the script into the ISE and run it line for line till you get there then take a look at the value of $_

Prior to Internet Explorer 8 there were no support for Media queries. But depending on your case you can try to use conditional comments to target only Internet Explorer 8 and lower. You just have to use a proper CSS files architecture.

Flags (or compiler options) are nothing but ordinary command line arguments passed to the compiler executable.

Assuming you are invoking g++ from the command line (terminal):

$ g++ -std=c++11 your_file.cpp -o your_program

or

$ g++ -std=c++0x your_file.cpp -o your_program

if the above doesn't work.

Local variables are automatically freed when the function ends, you don't need to free them by yourself. You only free dynamically allocated memory (e.g using malloc) as it's allocated on the heap:

char *arr = malloc(3 * sizeof(char));
strcpy(arr, "bo");
// ...
free(arr);

Here is the Kotlin version I use for reachability checking,

Kotlin MyReachability

object MyReachability {

    private val REACHABILITY_SERVER = "http://google.com" // can be any URL you want

    private fun hasNetworkAvailable(context: Context): Boolean {
        val service = Context.CONNECTIVITY_SERVICE
        val manager = context.getSystemService(service) as ConnectivityManager?
        val network = manager?.activeNetworkInfo
        Log.d(classTag, "hasNetworkAvailable: ${(network != null)}")
        return (network != null)
    }

    fun hasInternetConnected(context: Context): Boolean {
        if (hasNetworkAvailable(context)) {
            try {
                val connection = URL(REACHABILITY_SERVER).openConnection() as HttpURLConnection
                connection.setRequestProperty("User-Agent", "Test")
                connection.setRequestProperty("Connection", "close")
                connection.connectTimeout = 1500
                connection.connect()
                Log.d(classTag, "hasInternetConnected: ${(connection.responseCode == 200)}")
                return (connection.responseCode == 200)
            } catch (e: IOException) {
                Log.e(classTag, "Error checking internet connection", e)
            }
        } else {
            Log.w(classTag, "No network available!")
        }
        Log.d(classTag, "hasInternetConnected: false")
        return false
    }
}

You can even pass the REACHABILITY_SERVER as param based on policy and restrictions, for example when you are in china you can check https://baidu.com rather https://google.com.

Calling example,

val webLoaderThread = Thread {
   if (MyReachability.hasInternetConnected(this)){
       runOnUiThread {
           //mWebView.loadUrl(LANDING_SERVER) // connected
       }
   } else {
       runOnUiThread {
           //showDialogNoNetwork() // not connected
       }
   }
}
webLoaderThread.start()

Android permissions

Dont forget to add these below permissions to your AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

If you want to delete for example the last 3 commits, run the following command to remove the changes from the file system (working tree) and commit history (index) on your local branch:

git reset --hard HEAD~3

Then run the following command (on your local machine) to force the remote branch to rewrite its history:

git push --force

Congratulations! All DONE!

Some notes:

You can retrieve the desired commit id by running

git log

Then you can replace HEAD~N with <desired-commit-id> like this:

git reset --hard <desired-commit-id>

If you want to keep changes on file system and just modify index (commit history), use --soft flag like git reset --soft HEAD~3. Then you have chance to check your latest changes and keep or drop all or parts of them. In the latter case runnig git status shows the files changed since <desired-commit-id>. If you use --hard option, git status will tell you that your local branch is exactly the same as the remote one. If you don't use --hard nor --soft, the default mode is used that is --mixed. In this mode, git help reset says:

Resets the index but not the working tree (i.e., the changed files are preserved but not marked for commit) and reports what has not been updated.

Save the following script as something like findPK.sql.

set verify off
accept TABLE_NAME char prompt 'Table name>'

SELECT cols.column_name
FROM all_constraints cons NATURAL JOIN all_cons_columns cols
WHERE cons.constraint_type = 'P' AND table_name = UPPER('&TABLE_NAME');

It can then be called using

@findPK

In order to make Erik B's great solution more useable across the different UIVIewCOntrollers of your app I recommend adding a category for UIViewController and declare his setTitle:title method inside. Like this you will get the title color change on all view controllers without the need of duplication.

One thing to note though is that you do not need [super setTItle:tilte]; in Erik's code and that you will need to explicitly call self.title = @"my new title" in your view controllers for this method to be called

@implementation UIViewController (CustomeTitleColor)

- (void)setTitle:(NSString *)title
{
    UILabel *titleView = (UILabel *)self.navigationItem.titleView;
    if (!titleView) {
        titleView = [[UILabel alloc] initWithFrame:CGRectZero];
        titleView.backgroundColor = [UIColor clearColor];
        titleView.font = [UIFont boldSystemFontOfSize:20.0];
        titleView.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];

        titleView.textColor = [UIColor blueColor]; // Change to desired color

        self.navigationItem.titleView = titleView;
        [titleView release];
    }
    titleView.text = title;
    [titleView sizeToFit];
}

@end

In Python 3.5+, encode the string to bytes and use the hex() method, returning a string.

s = "hello".encode("utf-8").hex()
s
# '68656c6c6f'

Optionally convert the string back to bytes:

b = bytes(s, "utf-8")
b
# b'68656c6c6f'

Using os.path

To get the parent directory of the directory containing the script (regardless of the current working directory), you'll need to use __file__.

Inside the script use os.path.abspath(__file__) to obtain the absolute path of the script, and call os.path.dirname twice:

from os.path import dirname, abspath
d = dirname(dirname(abspath(__file__))) # /home/kristina/desire-directory

Basically, you can walk up the directory tree by calling os.path.dirname as many times as needed. Example:

In [4]: from os.path import dirname

In [5]: dirname('/home/kristina/desire-directory/scripts/script.py')
Out[5]: '/home/kristina/desire-directory/scripts'

In [6]: dirname(dirname('/home/kristina/desire-directory/scripts/script.py'))
Out[6]: '/home/kristina/desire-directory'

If you want to get the parent directory of the current working directory, use os.getcwd:

import os
d = os.path.dirname(os.getcwd())

Using pathlib

You could also use the pathlib module (available in Python 3.4 or newer).

Each pathlib.Path instance have the parent attribute referring to the parent directory, as well as the parents attribute, which is a list of ancestors of the path. Path.resolve may be used to obtain the absolute path. It also resolves all symlinks, but you may use Path.absolute instead if that isn't a desired behaviour.

Path(__file__) and Path() represent the script path and the current working directory respectively, therefore in order to get the parent directory of the script directory (regardless of the current working directory) you would use

from pathlib import Path
# `path.parents[1]` is the same as `path.parent.parent`
d = Path(__file__).resolve().parents[1] # Path('/home/kristina/desire-directory')

and to get the parent directory of the current working directory

from pathlib import Path
d = Path().resolve().parent

Note that d is a Path instance, which isn't always handy. You can convert it to str easily when you need it:

In [15]: str(d)
Out[15]: '/home/kristina/desire-directory'

Classic mode (the only mode in IIS6 and below) is a mode where IIS only works with ISAPI extensions and ISAPI filters directly. In fact, in this mode, ASP.NET is just an ISAPI extension (aspnet_isapi.dll) and an ISAPI filter (aspnet_filter.dll). IIS just treats ASP.NET as an external plugin implemented in ISAPI and works with it like a black box (and only when it's needs to give out the request to ASP.NET). In this mode, ASP.NET is not much different from PHP or other technologies for IIS.

Integrated mode, on the other hand, is a new mode in IIS7 where IIS pipeline is tightly integrated (i.e. is just the same) as ASP.NET request pipeline. ASP.NET can see every request it wants to and manipulate things along the way. ASP.NET is no longer treated as an external plugin. It's completely blended and integrated in IIS. In this mode, ASP.NET HttpModules basically have nearly as much power as an ISAPI filter would have had and ASP.NET HttpHandlers can have nearly equivalent capability as an ISAPI extension could have. In this mode, ASP.NET is basically a part of IIS.

As stated above, ?? is the null coalescing operator. So the equivalent to

(Age ?? 0) == 0

without using the ?? operator is

(!Age.HasValue) || Age == 0

However, there is no version of .Net that has Nullable< T > but not ??, so your statement,

Now i have to check in a older application where the declaration part is not in ternary.

is doubly invalid.

LEFT ('BTA200', 3) will work for the examples you have given, as in :

SELECT LEFT(MyField, 3)
FROM MyTable

To extract the numeric part, you can use this code

SELECT RIGHT(MyField, LEN(MyField) - 3)
FROM MyTable
WHERE MyField LIKE 'BTA%' 
--Only have this test if your data does not always start with BTA.

The way to solve your problem is to use a Win32 API called WNetUseConnection.
Use this function to connect to a UNC path with authentication, NOT to map a drive.

This will allow you to connect to a remote machine, even if it is not on the same domain, and even if it has a different username and password.

Once you have used WNetUseConnection you will be able to access the file via a UNC path as if you were on the same domain. The best way is probably through the administrative built in shares.
Example: \\computername\c$\program files\Folder\file.txt

Here is some sample C# code that uses WNetUseConnection.
Note, for the NetResource, you should pass null for the lpLocalName and lpProvider. The dwType should be RESOURCETYPE_DISK. The lpRemoteName should be \\ComputerName.

dex file is a file that is executed on the Dalvik VM.

Dalvik VM includes several features for performance optimization, verification, and monitoring, one of which is Dalvik Executable (DEX).

Java source code is compiled by the Java compiler into .class files. Then the dx (dexer) tool, part of the Android SDK processes the .class files into a file format called DEX that contains Dalvik byte code. The dx tool eliminates all the redundant information that is present in the classes. In DEX all the classes of the application are packed into one file. The following table provides comparison between code sizes for JVM jar files and the files processed by the dex tool.

The table compares code sizes for system libraries, web browser applications, and a general purpose application (alarm clock app). In all cases dex tool reduced size of the code by more than 50%.

In standard Java environments each class in Java code results in one .class file. That means, if the Java source code file has one public class and two anonymous classes, let’s say for event handling, then the java compiler will create total three .class files.

The compilation step is same on the Android platform, thus resulting in multiple .class files. But after .class files are generated, the “dx” tool is used to convert all .class files into a single .dex, or Dalvik Executable, file. It is the .dex file that is executed on the Dalvik VM. The .dex file has been optimized for memory usage and the design is primarily driven by sharing of data.

there are two way:

First :

Inside your CD of SQL Server 2012

you can go to this path \redist\VisualStudioShell.

And you most install this file VS10sp1-KB983509.msp.

After several minutes your problem fix.

Restart your computer and then fire SetUp of SQL Server 2012.

See this picture.

Secound :

And press download.

After download run this exe file and let it download and fix your VS2010 to VS2010 SP1.

And then restart your windows.

After this operation you can install SQL Server 2012

I had the same error, then I tried <asp:PostBackTrigger ControlID="xyz"/> instead of AsyncPostBackTrigger .This worked for me. It is because we don't want a partial postback.

Your array is occupying roughly 8 GB of memory (1,000 x 1,000,000 x sizeof(double) bytes). That might be a factor in your problem. It is a global variable rather than a stack variable, so you may be OK, but you're pushing limits here.

Writing that much data to a file is going to take a while.

You don't check that the file was opened successfully, which could be a source of trouble, too (if it did fail, a segmentation fault is very likely).

You really should introduce some named constants for 1,000 and 1,000,000; what do they represent?

You should also write a function to do the calculation; you could use an inline function in C99 or later (or C++). The repetition in the code is excruciating to behold.

You should also use C99 notation for main(), with the explicit return type (and preferably void for the argument list when you are not using argc or argv):

int main(void)

Out of idle curiosity, I took a copy of your code, changed all occurrences of 1000 to ROWS, all occurrences of 1000000 to COLS, and then created enum { ROWS = 1000, COLS = 10000 }; (thereby reducing the problem size by a factor of 100). I made a few minor changes so it would compile cleanly under my preferred set of compilation options (nothing serious: static in front of the functions, and the main array; file becomes a local to main; error check the fopen(), etc.).

I then created a second copy and created an inline function to do the repeated calculation, (and a second one to do subscript calculations). This means that the monstrous expression is only written out once — which is highly desirable as it ensure consistency.

This program writes to P2.txt instead of P1.txt. I ran both programs and compared the output files; the output was identical. When I ran the programs on a mostly idle machine (MacBook Pro, 2.3 GHz Intel Core i7, 16 GiB 1333 MHz RAM, Mac OS X 10.7.5, GCC 4.7.1), I got reasonably but not wholly consistent timing:

However, almost all that time is spent on disk I/O. I reduced the disk I/O to just the very last row of data, so the outer I/O for loop became:

for (int i = COLS - 1; i < COLS; i++)

the timings were vastly reduced and very much more consistent:

The simplification in the code from having the ghastly expression written out just once is very beneficial, it seems to me. I'd certainly far rather have to maintain that program than the original.

You need to use the command echo $PATH to display the PATH variable or you can just execute set or env to display all of your environment variables.

By typing $PATH you tried to run your PATH variable contents as a command name.

Bash displayed the contents of your path any way. Based on your output the following directories will be searched in the following order:

/usr/local/share/npm/bin
/Library/Frameworks/Python.framework/Versions/2.7/bin
/usr/local/bin
/usr/local/sbin

To me this list appears to be complete.

Getting the anchor point of a div/table (left) = $("#whatever").offset().left; - ok!

Getting the anchor point of a div/table (right) you can use the code below.

 $("#whatever").width();

As far as I know, can't you just make it abstract?

class parent {
public:
  virtual void handle_event(int something) const = 0 {
    // boring default code
  }
};

I thought I read on www.parashift.com that you can actually implement an abstract method. Which makes sense to me personally, the only thing it does is force subclasses to implement it, no one said anything about it not being allowed to have an implementation itself.

Is a decent approximation on big screens. Its not good, but a good dirty fix.

The simplest way would be to use FOpen or one of FOpen's Wrappers.

$page = file_get_contents("http://www.domain.com/filename");

This does require FOpen which some web hosts disable and some web hosts will allow FOpen, but not allow access to external files. You may want to check where you are going to run the script to see if you have access to External FOpen.

You may want to look at jQuery Sortable. I used it to reorder table rows.

To encrypt:

byte[] encrpt= text.getBytes("UTF-8");
String base64 = Base64.encodeToString(encrpt, Base64.DEFAULT);

To decrypt:

byte[] decrypt= Base64.decode(base64, Base64.DEFAULT);
String text = new String(decrypt, "UTF-8");

To get this to work for me I had to drill down in the Python directory using the Python command prompt (on WIN10 from VS CODE). In my case it was in my "AppData\Local\Programs\Python\python35-32" directory. From there now I ran the command...

python -m pip install --upgrade pip

This worked and I'm good to go.

The simplest way is to use the JsonPrimitive class, which derives from JsonElement, as shown below:

JsonElement element = new JsonPrimitive(yourString);
JsonObject result = element.getAsJsonObject();

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

The short answer is NO, PDO prepares will not defend you from all possible SQL-Injection attacks. For certain obscure edge-cases.

I'm adapting this answer to talk about PDO...

The long answer isn't so easy. It's based off an attack demonstrated here.

The Attack

So, let's start off by showing the attack...

$pdo->query('SET NAMES gbk');
$var = "\xbf\x27 OR 1=1 /*";
$query = 'SELECT * FROM test WHERE name = ? LIMIT 1';
$stmt = $pdo->prepare($query);
$stmt->execute(array($var));

In certain circumstances, that will return more than 1 row. Let's dissect what's going on here:

1. Selecting a Character Set

   $pdo->query('SET NAMES gbk');
   

   For this attack to work, we need the encoding that the server's expecting on the connection both to encode ' as in ASCII i.e. 0x27 and to have some character whose final byte is an ASCII \ i.e. 0x5c. As it turns out, there are 5 such encodings supported in MySQL 5.6 by default: big5, cp932, gb2312, gbk and sjis. We'll select gbk here.

   Now, it's very important to note the use of SET NAMES here. This sets the character set ON THE SERVER. There is another way of doing it, but we'll get there soon enough.

2. The Payload

   The payload we're going to use for this injection starts with the byte sequence 0xbf27. In gbk, that's an invalid multibyte character; in latin1, it's the string ¿'. Note that in latin1 and gbk, 0x27 on its own is a literal ' character.

   We have chosen this payload because, if we called addslashes() on it, we'd insert an ASCII \ i.e. 0x5c, before the ' character. So we'd wind up with 0xbf5c27, which in gbk is a two character sequence: 0xbf5c followed by 0x27. Or in other words, a valid character followed by an unescaped '. But we're not using addslashes(). So on to the next step...

3. $stmt->execute()

   The important thing to realize here is that PDO by default does NOT do true prepared statements. It emulates them (for MySQL). Therefore, PDO internally builds the query string, calling mysql_real_escape_string() (the MySQL C API function) on each bound string value.

   The C API call to mysql_real_escape_string() differs from addslashes() in that it knows the connection character set. So it can perform the escaping properly for the character set that the server is expecting. However, up to this point, the client thinks that we're still using latin1 for the connection, because we never told it otherwise. We did tell the server we're using gbk, but the client still thinks it's latin1.

   Therefore the call to mysql_real_escape_string() inserts the backslash, and we have a free hanging ' character in our "escaped" content! In fact, if we were to look at $var in the gbk character set, we'd see:

   ?' OR 1=1 /*

   Which is exactly what the attack requires.

4. The Query

   This part is just a formality, but here's the rendered query:

   SELECT * FROM test WHERE name = '?' OR 1=1 /*' LIMIT 1
   

Congratulations, you just successfully attacked a program using PDO Prepared Statements...

The Simple Fix

Now, it's worth noting that you can prevent this by disabling emulated prepared statements:

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

This will usually result in a true prepared statement (i.e. the data being sent over in a separate packet from the query). However, be aware that PDO will silently fallback to emulating statements that MySQL can't prepare natively: those that it can are listed in the manual, but beware to select the appropriate server version).

The Correct Fix

The problem here is that we didn't call the C API's mysql_set_charset() instead of SET NAMES. If we did, we'd be fine provided we are using a MySQL release since 2006.

If you're using an earlier MySQL release, then a bug in mysql_real_escape_string() meant that invalid multibyte characters such as those in our payload were treated as single bytes for escaping purposes even if the client had been correctly informed of the connection encoding and so this attack would still succeed. The bug was fixed in MySQL 4.1.20, 5.0.22 and 5.1.11.

But the worst part is that PDO didn't expose the C API for mysql_set_charset() until 5.3.6, so in prior versions it cannot prevent this attack for every possible command! It's now exposed as a DSN parameter, which should be used instead of SET NAMES...

The Saving Grace

As we said at the outset, for this attack to work the database connection must be encoded using a vulnerable character set. utf8mb4 is not vulnerable and yet can support every Unicode character: so you could elect to use that instead—but it has only been available since MySQL 5.5.3. An alternative is utf8, which is also not vulnerable and can support the whole of the Unicode Basic Multilingual Plane.

Alternatively, you can enable the NO_BACKSLASH_ESCAPES SQL mode, which (amongst other things) alters the operation of mysql_real_escape_string(). With this mode enabled, 0x27 will be replaced with 0x2727 rather than 0x5c27 and thus the escaping process cannot create valid characters in any of the vulnerable encodings where they did not exist previously (i.e. 0xbf27 is still 0xbf27 etc.)—so the server will still reject the string as invalid. However, see @eggyal's answer for a different vulnerability that can arise from using this SQL mode (albeit not with PDO).

Safe Examples

The following examples are safe:

mysql_query('SET NAMES utf8');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because the server's expecting utf8...

mysql_set_charset('gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because we've properly set the character set so the client and the server match.

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've turned off emulated prepared statements.

$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=gbk', $user, $password);
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've set the character set properly.

$mysqli->query('SET NAMES gbk');
$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "\xbf\x27 OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

Because MySQLi does true prepared statements all the time.

Wrapping Up

If you:

• Use Modern Versions of MySQL (late 5.1, all 5.5, 5.6, etc) AND PDO's DSN charset parameter (in PHP = 5.3.6)

OR

• Don't use a vulnerable character set for connection encoding (you only use utf8 / latin1 / ascii / etc)

OR

• Enable NO_BACKSLASH_ESCAPES SQL mode

You're 100% safe.

Otherwise, you're vulnerable even though you're using PDO Prepared Statements...

Addendum

I've been slowly working on a patch to change the default to not emulate prepares for a future version of PHP. The problem that I'm running into is that a LOT of tests break when I do that. One problem is that emulated prepares will only throw syntax errors on execute, but true prepares will throw errors on prepare. So that can cause issues (and is part of the reason tests are borking).

If you are using Notepad++ editor (like the tag of the question suggests), you can use the great "Find in Files" functionality.

Go to Search → Find in Files (Ctrl+Shift+F for the keyboard addicted) and enter:

• Find What = (cat|town)

• Filters = *.txt

• Directory = enter the path of the directory you want to search in. You can check Follow current doc. to have the path of the current file to be filled.

• Search mode = Regular Expression

This answer is written for C++ developers, because I was haunted by such problem as one. Here is the solution:

Instead of

main()
{

}

please type

int main()
{

}

so the main function can be executed.

By the way, if you compile a C/C++ source file with no main function to execute, there will definitely be a bug message saying:

"[Error] Id returned 1 exist status"

But sometimes we just don't need main function in the file, in such a case, just ignore the bug message.

I solved the problem by following the instructions on msdn.microsoft.com more closely. There, it is stated that one must create the new macro by selecting Developer -> Macros, typing a new macro name, and clicking "Create". Creating the macro in this way, I was able to run it (see message box below).

Using pip install graphviz had good feedback in terminal, but lead to this error when I tried to make a graph in a Jupyter notebook. I then ran brew install graphviz, which gave an error in terminal. Then I ran conda install graphviz and the graph worked.

From @Leighton's comment: pip only gets path problem same as yours and conda only gets import error.

I would like to point out that if you can't find "Link Binaries With Libraries" in your build phases tab click the "Add build phase" button in the lower right corner.

I would suggest using the replace-last npm package.

var str = 'one two, one three, one four, one';_x000D_
var result = replaceLast(str, 'one', 'finish');_x000D_
console.log(result);

<script src="https://unpkg.com/replace-last@latest/replaceLast.js"></script>

This works for string and regex replacements.

^{The original query used user variables and ORDER BY on derived tables; the behavior of both quirks is not guaranteed. Revised answer as follows.}

In MySQL 5.x you can use poor man's rank over partition to achieve desired result. Just outer join the table with itself and for each row, count the number of rows lesser than it. In the above case, lesser row is the one with higher rate:

SELECT t.id, t.rate, t.year, COUNT(l.rate) AS rank
FROM t
LEFT JOIN t AS l ON t.id = l.id AND t.rate < l.rate
GROUP BY t.id, t.rate, t.year
HAVING COUNT(l.rate) < 5
ORDER BY t.id, t.rate DESC, t.year

Demo and Result:

| id  | rate | year | rank |
|-----|------|------|------|
| p01 |  8.0 | 2006 | 0    |
| p01 |  7.4 | 2003 | 1    |
| p01 |  6.8 | 2008 | 2    |
| p01 |  5.9 | 2001 | 3    |
| p01 |  5.3 | 2007 | 4    |
| p02 | 12.5 | 2001 | 0    |
| p02 | 12.4 | 2004 | 1    |
| p02 | 12.2 | 2002 | 2    |
| p02 | 10.3 | 2003 | 3    |
| p02 |  8.7 | 2000 | 4    |

Note that if the rates had ties, for example:

100, 90, 90, 80, 80, 80, 70, 60, 50, 40, ...

The above query will return 6 rows:

100, 90, 90, 80, 80, 80

Change to HAVING COUNT(DISTINCT l.rate) < 5 to get 8 rows:

100, 90, 90, 80, 80, 80, 70, 60

Or change to ON t.id = l.id AND (t.rate < l.rate OR (t.rate = l.rate AND t.pri_key > l.pri_key)) to get 5 rows:

 100, 90, 90, 80, 80

In MySQL 8 or later just use the RANK, DENSE_RANK or ROW_NUMBER functions:

SELECT *
FROM (
    SELECT *, RANK() OVER (PARTITION BY id ORDER BY rate DESC) AS rnk
    FROM t
) AS x
WHERE rnk <= 5

let Str = "12"
let num: Int = 0
num = Int (str)

Getting encoding right is really tricky - there are too many layers:

• Browser
• Page
• PHP
• MySQL

The SQL command "SET CHARSET utf8" from PHP will ensure that the client side (PHP) will get the data in utf8, no matter how they are stored in the database. Of course, they need to be stored correctly first.

DDL definition vs. real data

Encoding defined for a table/column doesn't really mean that the data are in that encoding. If you happened to have a table defined as utf8 but stored as differtent encoding, then MySQL will treat them as utf8 and you're in trouble. Which means you have to fix this first.

What to check

You need to check in what encoding the data flow at each layer.

• Check HTTP headers, headers.
• Check what's really sent in body of the request.
• Don't forget that MySQL has encoding almost everywhere:
  • Database
  • Tables
  • Columns
  • Server as a whole
  • Client
    Make sure that there's the right one everywhere.

Conversion

If you receive data in e.g. windows-1250, and want to store in utf-8, then use this SQL before storing:

SET NAMES 'cp1250';

If you have data in DB as windows-1250 and want to retreive utf8, use:

SET CHARSET 'utf8';

Few more notes:

• Don't rely on too "smart" tools to show the data. E.g. phpMyAdmin does (was doing when I was using it) encoding really bad. And it goes through all the layers so it's hard to find out.
• Also, Internet Explorer had really stupid behavior of "guessing" the encoding based on weird rules.
• Use simple editors where you can switch encoding. I recommend MySQL Workbench.

From the docs:

from .. import scriptA

You can do this in packages, but not in scripts you run directly. From the link above:

Note that both explicit and implicit relative imports are based on the name of the current module. Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application should always use absolute imports.

If you create a script that imports A.B.B, you won't receive the ValueError.

Broadcast receivers receive events of a certain type. I don't think you can invoke them by class name.

First, your IntentFilter must contain an event.

static final String SOME_ACTION = "com.yourcompany.yourapp.SOME_ACTION";
IntentFilter intentFilter = new IntentFilter(SOME_ACTION);

Second, when you send a broadcast, use this same action:

Intent i = new Intent(SOME_ACTION);
sendBroadcast(i);

Third, do you really need MyIntentService to be inline? Static? [EDIT] I discovered that MyIntentSerivce MUST be static if it is inline.

Fourth, is your service declared in the AndroidManifest.xml?

As an addendum, if you want to reapply your changes on top of the remote, you can also try:

git pull --rebase origin master

If you then want to undo some of your changes (but perhaps not all of them) you can use:

git reset SHA_HASH

Then do some adjustment and recommit.

Here is the complete process to create a local repo and push the changes to new remote branch

1. Creating local repository:-

   Initially user may have created the local git repository.

   $ git init :- This will make the local folder as Git repository,

2. Link the remote branch:-

   Now challenge is associate the local git repository with remote master branch.

   $ git remote add RepoName RepoURL

   usage: git remote add []

3. Test the Remote

   $ git remote show --->Display the remote name

   $ git remote -v --->Display the remote branches

4. Now Push to remote

   $git add . ----> Add all the files and folder as git staged'

   $git commit -m "Your Commit Message" - - - >Commit the message

   $git push - - - - >Push the changes to the upstream

Even though multiple requests can be sent over the same HTTP connection, the server does not attach any special meaning to their arriving over the same socket. That is solely a performance thing, intended to minimize the time/bandwidth that'd otherwise be spent reestablishing a connection for each request.

As far as HTTP is concerned, they are all still separate requests and must contain enough information on their own to fulfill the request. That is the essence of "statelessness". Requests will not be associated with each other absent some shared info the server knows about, which in most cases is a session ID in a cookie.

Compact solution (provided you don't need other environment variables):

call('sqsub -np {} /homedir/anotherdir/executable'.format(var1).split(),
      env=dict(LD_LIBRARY_PATH=my_path))

Using the env command line tool:

call('env LD_LIBRARY_PATH=my_path sqsub -np {} /homedir/anotherdir/executable'.format(var1).split())

Object initializers were introduced in C# 3.0, check which framework version you are targeting.

Overview of C# 3.0

I'm posting this solution because I had a hard time finding what I needed. This post got me close enough (+1 for that thank you), and here is the final solution for rearranging column data before insert if the data matches a test.

Note: this is from a legacy project I inherited where:

1. The Unique Key is a composite of rridprefix + rrid
2. Before I took over there was no constraint preventing duplicate unique keys
3. We needed to combine two tables (one full of duplicates) into the main table which now has the constraint on the composite key (so merging fails because the gaining table won't allow the duplicates from the unclean table)
4. on duplicate key is less than ideal because the columns are too numerous and may change

Anyway, here is the trigger that puts any duplicate keys into a legacy column while allowing us to store the legacy, bad data (and not trigger the gaining tables composite, unique key).

BEGIN
  -- prevent duplicate composite keys when merging in archive to main
  SET @EXIST_COMPOSITE_KEY = (SELECT count(*) FROM patientrecords where rridprefix = NEW.rridprefix and rrid = NEW.rrid);

  -- if the composite key to be introduced during merge exists, rearrange the data for insert
  IF @EXIST_COMPOSITE_KEY > 0
  THEN

    -- set the incoming column data this way (if composite key exists)

    -- the legacy duplicate rrid field will help us keep the bad data
    SET NEW.legacyduperrid = NEW.rrid;

    -- allow the following block to set the new rrid appropriately
    SET NEW.rrid = null;

  END IF;

  -- legacy code tried set the rrid (race condition), now the db does it
  SET NEW.rrid = (
    SELECT if(NEW.rrid is null and NEW.legacyduperrid is null, IFNULL(MAX(rrid), 0) + 1, NEW.rrid)
    FROM patientrecords
    WHERE rridprefix  = NEW.rridprefix
  );
END

If you're using Java 9, there's an easy way with less number of lines without needing to initialize or add method.

List<String> list = List.of("first", "second", "third");

Option 1

You could also solve it by adding a transparent border to the row (tr), like this

HTML

<table>
    <tr> 
         <td>1</td>
    </tr>
    <tr> 
         <td>2</td>
    </tr>
</table>

CSS

tr {
    border-top: 12px solid transparent;
    border-bottom: 12px solid transparent;
}

Works like a charm, although if you need regular borders, then this method will sadly not work.

Option 2

Since rows act as a way to group cells, the correct way to do this, would be to use

table {
    border-collapse: inherit;
    border-spacing: 0 10px;
}

[Edit] Read this answer. It explains why multiline lambda is not a thing.

Simply put, it's unpythonic. From Guido van Rossum's blog post:

I find any solution unacceptable that embeds an indentation-based block in the middle of an expression. Since I find alternative syntax for statement grouping (e.g. braces or begin/end keywords) equally unacceptable, this pretty much makes a multi-line lambda an unsolvable puzzle.

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

Now with Java EE 7 you can find the resource more easily with

InputStream resource = getServletContext().getResourceAsStream("/WEB-INF/my.json");

https://docs.oracle.com/javaee/7/api/javax/servlet/GenericServlet.html#getServletContext--

I know this is a while ago but I encountered this and followed the other answers here but to no avail, I found the solution via this question (Stackoverflow Question)

Essentially just needed to edit the php.ini file (mine was found at c:\xampp\php\php.ini) and uncomment these lines...

;extension=php_mysql.dll
;extension=php_mysqli.dll
;extension=php_pdo_mysql.dll

After restarting apache all was working as expected.

• You can map commands that normally manipulate buffers to manipulate tabs, as I've done with gf in my .vimrc:

  map gf :tabe <cfile><CR>
  

  I'm sure you can do the same with [^

• I don't think vim supports this for tabs (yet). I use gt and gT to move to the next and previous tabs, respectively. You can also use Ngt, where N is the tab number. One peeve I have is that, by default, the tab number is not displayed in the tab line. To fix this, I put a couple functions at the end of my .vimrc file (I didn't paste here because it's long and didn't format correctly).

Are you getting errors, or just not sure where to start?

%pylab inline
import pandas as pd
import matplotlib.pyplot as plt

df2 = df.groupby(['Name', 'Abuse/NFF'])['Name'].count().unstack('Abuse/NFF').fillna(0)
df2[['abuse','nff']].plot(kind='bar', stacked=True)

This can be done by enabling short_open_tag in php.ini:

short_open_tag = on

If you don't have access to the php.ini you can try to enable them trough the .htaccess file but it's possible the hosting company disabled this if you are on shared hosting:

php_value short_open_tag 1

For the people thinking that short_open_tags are bad practice as of php 5.4 the <?= ... ?> shorttag will supported everywhere, regardless of the settings so there is no reason not to use them if you can control the settings on the server. Also said in this link: short_open_tag

scanner.useDelimiter(",");

This should work.

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;


public class TestScanner {

    public static void main(String[] args) throws FileNotFoundException {
        Scanner scanner = new Scanner(new File("/Users/pankaj/abc.csv"));
        scanner.useDelimiter(",");
        while(scanner.hasNext()){
            System.out.print(scanner.next()+"|");
        }
        scanner.close();
    }

}

For CSV File:

a,b,c d,e
1,2,3 4,5
X,Y,Z A,B

Output is:

a|b|c d|e
1|2|3 4|5
X|Y|Z A|B|

$("#selectsearch").change(function() {
  var action = $(this).val() == "people" ? "user" : "content";
  $("#search-form").attr("action", "/search/" + action);
});

When using the sublime text editor, I was able to select the segment of my code that was giving me the inconsistent use of tabs and spaces in indentation error and select:

view > indentation > convert indentation to spaces

which resolved the issue for me.

Supposing that you are using ECLIPSE:

Right click PROJECT PROPERTIES ANDROID

If you have a version of ANDROID checked, you must change it to a GOOGLE API. Choose a version of GOOGLE APIS compatible with your project's target version.

+1 simple and cross-browser way: You can also put transparent picture over the video with css z-index and opacity. So users will see "save picture as" instead of "save video" in context menu.

If you are using vscode's terminal then it might not work even if you do the environment variable thing, test by typing git

Restart vscode, it should work.

Also u can check

Project Structure -> Default Config -> Signing Config

after u add all that u need

function doPoll(){
    $.post('ajax/test.html', function(data) {
        alert(data);  // process results here
        setTimeout(doPoll,5000);
    });
}

Unless there's a way to retrieve the old index of the elements after they've been shuffled, I'd do it one of two ways:

A) Make another list multi_shuffler = [0, 1, 2, ... , file.size()] and shuffle it. Loop over it to get the order for your shuffled file/image lists.

ArrayList newFileList = new ArrayList(); ArrayList newImgList = new ArrayList(); for ( i=0; i

or B) Make a StringWrapper class to hold the file/image names and combine the two lists you've already got into one: ArrayList combinedList;

Double check if you are not able to use keys.

Otherwise use expect:

#!/usr/bin/expect -f
spawn ssh [email protected]
expect "assword:"
send "mypassword\r"
interact

If you are using tomcat as your server runtime and you get this error in tests (because tomcat runtime is not available during tests) than it makes make sense to include tomcat el runtime instead of the one from glassfish). This would be:

    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-el-api</artifactId>
        <version>8.5.14</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-jasper-el</artifactId>
        <version>8.5.14</version>
        <scope>test</scope>
    </dependency>

Watch this video, I had the same question. He shows you how to debug the service as well.

Here are his instructions using the basic C# Windows Service template in Visual Studio 2010/2012.

You add this to the Service1.cs file:

public void onDebug()
{
    OnStart(null);
}

You change your Main() to call your service this way if you are in the DEBUG Active Solution Configuration.

static void Main()
{
    #if DEBUG
    //While debugging this section is used.
    Service1 myService = new Service1();
    myService.onDebug();
    System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);

    #else
    //In Release this section is used. This is the "normal" way.
    ServiceBase[] ServicesToRun;
    ServicesToRun = new ServiceBase[] 
    { 
        new Service1() 
    };
    ServiceBase.Run(ServicesToRun);
    #endif
}

Keep in mind that while this is an awesome way to debug your service. It doesn't call OnStop() unless you explicitly call it similar to the way we called OnStart(null) in the onDebug() function.

You could do it using SUBSTRING() function:

UPDATE table SET column = SUBSTRING(column, 0, LEN(column) + 1 - N)

Removes the last N characters from every row in the column

If you select a cell in an already selected range, it will not work. But, Selecting a range outside the original selection will clear the original selection.

'* The original selection *' ActiveSheet.range("A1:K10").Select

'* New Selections *' Activesheet.Range("L1").Select

'* Then *' Activesheet.Range("A1").Select

I was having the same problem. This worked for me:

.center {
    margin: 0 auto; 
    width: 400px;
    **display:block**
 }

Please try the below Code

You can split the controller (PageCtrl) and service (dataService)

'use strict';_x000D_
(function () {_x000D_
    angular.module('myApp')_x000D_
        .controller('pageContl', ['$scope', 'dataService', PageContl])_x000D_
        .service('dataService', ['$q', '$http', DataService]);_x000D_
    function DataService($q, $http){_x000D_
        this.$q = $q;_x000D_
        this.$http = $http;_x000D_
        //... blob blob _x000D_
    }_x000D_
    DataService.prototype = {_x000D_
        getSearchData: function () {_x000D_
            var deferred = this.$q.defer(); //initiating promise_x000D_
            this.$http({_x000D_
                method: 'POST',//GET_x000D_
                url: 'test.json',_x000D_
                headers: { 'Content-Type': 'application/json' }_x000D_
            }).then(function(result) {_x000D_
                deferred.resolve(result.data);_x000D_
            },function (error) {_x000D_
                deferred.reject(error);_x000D_
            });_x000D_
            return deferred.promise;_x000D_
        },_x000D_
        getABCDATA: function () {_x000D_
_x000D_
        }_x000D_
    };_x000D_
    function PageContl($scope, dataService) {_x000D_
        this.$scope = $scope;_x000D_
        this.dataService = dataService; //injecting service Dependency in ctrl_x000D_
        this.pageData = {}; //or [];_x000D_
    }_x000D_
    PageContl.prototype = {_x000D_
         searchData: function () {_x000D_
             var self = this; //we can't access 'this' of parent fn from callback or inner function, that's why assigning in temp variable_x000D_
             this.dataService.getSearchData().then(function (data) {_x000D_
                 self.searchData = data;_x000D_
             });_x000D_
         }_x000D_
    }_x000D_
}());

I don't know if this is the correct way however I did this:

<div class="control-group">
  <label class="control-label" for="id1">Label:</label>
  <div class="controls">
    <textarea id="id1" class="textareawidth" rows="10" name="anyname">value</textarea>
  </div>
</div>

and put this in my bootstrapcustom.css file:

@media (min-width: 768px) {
    .textareawidth {
        width:500px;
    }
}
@media (max-width: 767px) {
    .textareawidth {

    }
}

This way it resizes based on the viewport. Seems to line everything up nicely on a big browser and on a small mobile device.

For me it was solved in the following way with SQL Server Management studio -Log in as admin (I logged in as windows authentication) -Attach the mdf file (right click Database | attach | Add ) -Log out as admin -Log in as normal user

You can do it in pure CSS using the :after pseudo-element and getting creative with the margins.

Here's an example, using Font Awesome for the search icon:

.search-box-container input {_x000D_
  padding: 5px 20px 5px 5px;_x000D_
}_x000D_
_x000D_
.search-box-container:after {_x000D_
    content: "\f002";_x000D_
    font-family: FontAwesome;_x000D_
    margin-left: -25px;_x000D_
    margin-right: 25px;_x000D_
}

<!-- font awesome -->_x000D_
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
_x000D_
_x000D_
<div class="search-box-container">_x000D_
  <input type="text" placeholder="Search..."  />_x000D_
</div>

This is a very common question seen on Stackoverflow.

The important part here is not the command displayed in the error, but what the actual error tells you instead.

a Quick breakdown on why this error is received.

cmd.exe Being a terminal window relies on input and system Environment variables, in order to perform what you request it to do. it does NOT know the location of everything and it also does not know when to distinguish between commands or executable names which are separated by whitespace like space and tab or commands with whitespace as switch variables.

How do I fix this:

When Actual Command/executable fails

First we make sure, is the executable actually installed? If yes, continue with the rest, if not, install it first.

If you have any executable which you are attempting to run from cmd.exe then you need to tell cmd.exe where this file is located. There are 2 ways of doing this.

1. specify the full path to the file.

   "C:\My_Files\mycommand.exe"

2. Add the location of the file to your environment Variables.

Goto:
------> Control Panel-> System-> Advanced System Settings->Environment Variables

In the System Variables Window, locate path and select edit

Now simply add your path to the end of the string, seperated by a semicolon ; as:

;C:\My_Files\

Save the changes and exit. You need to make sure that ANY cmd.exe windows you had open are then closed and re-opened to allow it to re-import the environment variables. Now you should be able to run mycommand.exe from any path, within cmd.exe as the environment is aware of the path to it.

When C:\Program or Similar fails

This is a very simple error. Each string after a white space is seen as a different command in cmd.exe terminal, you simply have to enclose the entire path in double quotes in order for cmd.exe to see it as a single string, and not separate commands.

So to execute C:\Program Files\My-App\Mobile.exe simply run as:

"C:\Program Files\My-App\Mobile.exe"

These examples are minified because StackOverflow has a maximum character limit and links to external code are discouraged since links can break.
