To run it as a full daemon from a shell, you'll need to use setsid and redirect its output. You can redirect the output to a logfile, or to /dev/null to discard it. Assuming your script is called myscript.sh, use the following command:

setsid myscript.sh >/dev/null 2>&1 < /dev/null &

This will completely detach the process from your current shell (stdin, stdout and stderr). If you want to keep the output in a logfile, replace the first /dev/null with your /path/to/logfile.

You have to redirect the output, otherwise it will not run as a true daemon (it will depend on your shell to read and write output).

Call the pd.DataFrame constructor directly:

df = pd.DataFrame(table, columns=headers)
df

   Heading1  Heading2
0         1         2
1         3         4

If you have a char array allocated you can simply put a '\0' wherever you want. Then point a new char * pointer to the location just after the newly inserted '\0'.

This will destroy your original string though depending on where you put the '\0'

You need debounce!

Here is a jQuery plugin, and here is all you need to know about debounce. If you are coming here from Google and Underscore has found its way into the JSoup of your app, it has debounce baked right in!

The GO command isn't a Transact-SQL statement, but a special command recognized by several MS utilities including SQL Server Management Studio code editor.

The GO command is used to group SQL commands into batches which are sent to the server together. The commands included in the batch, that is, the set of commands since the last GO command or the start of the session, must be logically consistent. For example, you can't define a variable in one batch and then use it in another since the scope of the variable is limited to the batch in which it's defined.

Note: There is no magic to animating a gif: it is either an animated gif or it is not. If the gif is not visible, very likely the path to the gif is wrong - or, as in your case, the container (div/p/etc) is not large enough to display it. In your code sample, you did not specify height or width and that appeared to be problem.

If the gif is displayed but not animating, see reference links at very bottom of this answer.

Displaying the gif + overlay, however, is easier than you might think.

All you need are two absolute-position DIVs: an overlay div, and a div that contains your loading gif. Both have higher z-index than your page content, and the image has a higher z-index than the overlay - so they will display above the page when visible.

So, when the button is pressed, just unhide those two divs. That's it!

Once upon a midnight dreary, while I pondered weak and weary, over many a quaint and curious routine of forgotten code... While I nodded, nearly napping, suddenly there came a tapping... as of someone gently rapping - rapping at my office door. 'Tis the team leader, I muttered, tapping at my office door - only this and nothing more. Ah, distinctly I remember it was in the bleak December and each separate React print-out lay there crumpled on the floor. Eagerly I wished the morrow; vainly I had sought to borrow from Stack-O surcease from sorrow - sorrow for my routine's core. For the brilliant but unworking code my angels seem to just ignore. I'll be tweaking code... forevermore! - <a href="http://www.online-literature.com/poe/335/" target="_blank">Apologies To Poe</a></div>_x000D_

You might enjoy playing with the new backdrop-filter:blur(_px) css property that gives a blur effect to the underlying content, as used in above demo... (As of April 2020: works in Chrome, Edge, Safari, Android, but not yet in Firefox)

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

GRANTs on different objects are separate. GRANTing on a database doesn't GRANT rights to the schema within. Similiarly, GRANTing on a schema doesn't grant rights on the tables within.

If you have rights to SELECT from a table, but not the right to see it in the schema that contains it then you can't access the table.

The rights tests are done in order:

Do you have `USAGE` on the schema? 
    No:  Reject access. 
    Yes: Do you also have the appropriate rights on the table? 
        No:  Reject access. 
        Yes: Check column privileges.

Your confusion may arise from the fact that the public schema has a default GRANT of all rights to the role public, which every user/group is a member of. So everyone already has usage on that schema.

The phrase:

(assuming that the objects' own privilege requirements are also met)

Is saying that you must have USAGE on a schema to use objects within it, but having USAGE on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.

It's like a directory tree. If you create a directory somedir with file somefile within it then set it so that only your own user can access the directory or the file (mode rwx------ on the dir, mode rw------- on the file) then nobody else can list the directory to see that the file exists.

If you were to grant world-read rights on the file (mode rw-r--r--) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.

If you instead set rwx-r-xr-x on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.

You need to set both permissions for people to actually be able to view the file.

Same thing in Pg. You need both schema USAGE rights and object rights to perform an action on an object, like SELECT from a table.

(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECTing from pg_class directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)

You have two ways to do that:

METHOD 1. The secure way.

Put the images on /www/htdocs/

<?php
    $www_root = 'http://localhost/images';
    $dir = '/var/www/images';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if ( file_exists( $dir ) == false ) {
       echo 'Directory \'', $dir, '\' not found!';
    } else {
       $dir_contents = scandir( $dir );

        foreach ( $dir_contents as $file ) {
           $file_type = strtolower( end( explode('.', $file ) ) );
           if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
              echo '<img src="', $www_root, '/', $file, '" alt="', $file, '"/>';
           break;
           }
        }
    }
?>

METHOD 2. Unsecure but more flexible.

Put the images on any directory (apache must have permission to read the file).

<?php
    $dir = '/home/user/Pictures';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if ( file_exists( $dir ) == false ) {
       echo 'Directory \'', $dir, '\' not found!';
    } else {
       $dir_contents = scandir( $dir );

        foreach ( $dir_contents as $file ) {
           $file_type = strtolower( end( explode('.', $file ) ) );
           if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
              echo '<img src="file_viewer.php?file=', base64_encode($dir . '/' . $file), '" alt="', $file, '"/>';
           break;
           }
        }
    }
?>

And create another script to read the image file.

<?php
    $filename = base64_decode($_GET['file']);
    // Check the folder location to avoid exploit
    if (dirname($filename) == '/home/user/Pictures')
        echo file_get_contents($filename);
?>

To create a copy of the crop we want, we can do the following,

// Read img
cv::Mat img = cv::imread("imgFileName");
cv::Mat croppedImg;

// This line picks out the rectangle from the image
// and copies to a new Mat
img(cv::Rect(xMin,yMin,xMax-xMin,yMax-yMin)).copyTo(croppedImg);

// Display diff
cv::imshow( "Original Image",  img );
cv::imshow( "Cropped Image",  croppedImg);
cv::waitKey();

If you want to retrieve the form values (such as those that would be sent using an HTTP POST) you can use:

JavaScript

const formData = new FormData(document.querySelector('form'))
for (var pair of formData.entries()) {
  // console.log(pair[0] + ': ' + pair[1]);
}

form-serialize (https://code.google.com/archive/p/form-serialize/)

serialize(document.forms[0]);

jQuery

$("form").serializeArray()

It seems to be a long-running framework process for debugging (to decrease load times?). I discovered that when you start your application twice from the debugger often the same vshost.exe process will be used. It just unloads all user-loaded DLLs first. This does odd things if you are fooling around with API hooks from managed processes.

People often claim that printf is much faster. This is largely a myth. I just tested it, with the following results:

cout with only endl                     1461.310252 ms
cout with only '\n'                      343.080217 ms
printf with only '\n'                     90.295948 ms
cout with string constant and endl      1892.975381 ms
cout with string constant and '\n'       416.123446 ms
printf with string constant and '\n'     472.073070 ms
cout with some stuff and endl           3496.489748 ms
cout with some stuff and '\n'           2638.272046 ms
printf with some stuff and '\n'         2520.318314 ms

Conclusion: if you want only newlines, use printf; otherwise, cout is almost as fast, or even faster. More details can be found on my blog.

To be clear, I'm not trying to say that iostreams are always better than printf; I'm just trying to say that you should make an informed decision based on real data, not a wild guess based on some common, misleading assumption.

Update: Here's the full code I used for testing. Compiled with g++ without any additional options (apart from -lrt for the timing).

#include <stdio.h>
#include <iostream>
#include <ctime>

class TimedSection {
    char const *d_name;
    timespec d_start;
    public:
        TimedSection(char const *name) :

            timespec end;
            clock_gettime(CLOCK_REALTIME, &end);
            double duration = 1e3 * (end.tv_sec - d_start.tv_sec) +
                              1e-6 * (end.tv_nsec - d_start.tv_nsec);
            std::cerr << d_name << '\t' << std::fixed << duration << " ms\n"; 
        }
};

int main() {
    const int iters = 10000000;
    char const *text = "01234567890123456789";
    {
        TimedSection s("cout with only endl");
        for (int i = 0; i < iters; ++i)
            std::cout << std::endl;
    }
    {
        TimedSection s("cout with only '\\n'");
        for (int i = 0; i < iters; ++i)
            std::cout << '\n';
    }
    {
        TimedSection s("printf with only '\\n'");
        for (int i = 0; i < iters; ++i)
            printf("\n");
    }
    {
        TimedSection s("cout with string constant and endl");
        for (int i = 0; i < iters; ++i)
            std::cout << "01234567890123456789" << std::endl;
    }
    {
        TimedSection s("cout with string constant and '\\n'");
        for (int i = 0; i < iters; ++i)
            std::cout << "01234567890123456789\n";
    }
    {
        TimedSection s("printf with string constant and '\\n'");
        for (int i = 0; i < iters; ++i)
            printf("01234567890123456789\n");
    }
    {
        TimedSection s("cout with some stuff and endl");
        for (int i = 0; i < iters; ++i)
            std::cout << text << "01234567890123456789" << i << std::endl;
    }
    {
        TimedSection s("cout with some stuff and '\\n'");
        for (int i = 0; i < iters; ++i)
            std::cout << text << "01234567890123456789" << i << '\n';
    }
    {
        TimedSection s("printf with some stuff and '\\n'");
        for (int i = 0; i < iters; ++i)
            printf("%s01234567890123456789%i\n", text, i);
    }
}

If you need to both get the raw content from the request, but also need to use a bound model version of it in the controller, you will likely get this exception.

NotSupportedException: Specified method is not supported. 

For example, your controller might look like this, leaving you wondering why the solution above doesn't work for you:

public async Task<IActionResult> Index(WebhookRequest request)
{
    using var reader = new StreamReader(HttpContext.Request.Body);

    // this won't fix your string empty problems
    // because exception will be thrown
    reader.BaseStream.Seek(0, SeekOrigin.Begin); 
    var body = await reader.ReadToEndAsync();

    // Do stuff
}

You'll need to take your model binding out of the method parameters, and manually bind yourself:

public async Task<IActionResult> Index()
{
    using var reader = new StreamReader(HttpContext.Request.Body);

    // You shouldn't need this line anymore.
    // reader.BaseStream.Seek(0, SeekOrigin.Begin);

    // You now have the body string raw
    var body = await reader.ReadToEndAsync();

    // As well as a bound model
    var request = JsonConvert.DeserializeObject<WebhookRequest>(body);
}

It's easy to forget this, and I've solved this issue before in the past, but just now had to relearn the solution. Hopefully my answer here will be a good reminder for myself...

I'm not sure you have gotten past this yet, but I had to work on something very similar today and I got your fiddle working like you are asking, basically what I did was make another table row under it, and then used the accordion control. I tried using just collapse but could not get it working and saw an example somewhere on SO that used accordion.

Here's your updated fiddle: http://jsfiddle.net/whytheday/2Dj7Y/11/

Since I need to post code here is what each collapsible "section" should look like ->

<tr data-toggle="collapse" data-target="#demo1" class="accordion-toggle">
    <td>1</td>
    <td>05 May 2013</td>
    <td>Credit Account</td>
    <td class="text-success">$150.00</td>
    <td class="text-error"></td>
    <td class="text-success">$150.00</td>
</tr>

<tr>
    <td colspan="6" class="hiddenRow">
        <div class="accordion-body collapse" id="demo1">Demo1</div>
    </td>
</tr>

Note to Sinan and brian: perlfaq3 is still wrong.

See http://search.cpan.org/dist/B-C/perlcompile.pod

Please close the file if its still open on your computer, then try running the python code. I hope it works

Using reduce, you can do this in one Array.prototype function. This will fetch all even numbers from an array.

var arr = [1,2,3,4,5,6,7,8];_x000D_
_x000D_
var brr = arr.reduce((c, n) => {_x000D_
  if (n % 2 !== 0) {_x000D_
    return c;_x000D_
  }_x000D_
  c.push(n);_x000D_
  return c;_x000D_
}, []);_x000D_
_x000D_
document.getElementById('mypre').innerHTML = brr.toString();

<h1>Get all even numbers</h1>_x000D_
<pre id="mypre"> </pre>

You can use the same method and generalize it for your objects, like this.

var arr = options.reduce(function(c,n){
  if(somecondition) {return c;}
  c.push(n);
  return c;
}, []);

arr will now contain the filtered objects.

(I know the question is old, but I think this might be good as a reference for people with similar questions)

If you want to load data from an ASCII/text file (which has the benefit or being more or less human-readable and easy to parse in other software), numpy.loadtxt is probably what you want:

• http://docs.scipy.org/doc/numpy/reference/generated/numpy.loadtxt.html

If you just want to quickly save and load numpy arrays/matrices to and from a file, take a look at numpy.save and numpy.load:

• http://docs.scipy.org/doc/numpy/reference/generated/numpy.save.html
• http://docs.scipy.org/doc/numpy/reference/generated/numpy.load.html

In cpp, you need to pay special attention to string types when using execvp:

#include <iostream>
#include <string>
#include <cstring>
#include <stdio.h>
#include <unistd.h>
using namespace std;

const size_t MAX_ARGC = 15; // 1 command + # of arguments
char* argv[MAX_ARGC + 1]; // Needs +1 because of the null terminator at the end
// c_str() converts string to const char*, strdup converts const char* to char*
argv[0] = strdup(command.c_str());

// start filling up the arguments after the first command
size_t arg_i = 1;
while (cin && arg_i < MAX_ARGC) {
    string arg;
    cin >> arg;
    if (arg.empty()) {
        argv[arg_i] = nullptr;
        break;
    } else {
        argv[arg_i] = strdup(arg.c_str());
    }
    ++arg_i;
}

// Run the command with arguments
if (execvp(command.c_str(), argv) == -1) {
    // Print error if command not found
    cerr << "command '" << command << "' not found\n";
}

Reference: execlp?execvp?????

In the Windows command prompt you can use "tree /F" to view a tree of the current folder and all descending files & folders.

In File Explorer under Windows 8.1:

• Select folder
• Press Shift, right-click mouse, and select "Open command window here"
• Type tree /f > tree.txt and press Enter
• Use MS Word to open "tree.txt"
• The dialog box "File Conversion - tree.txt" will open
• For "Text encoding" tick the "MS-DOS" option

You now have an editable tree structure file.

This works for versions of Windows from Windows XP to Windows 8.1.

Assuming your string always starts with 'test_':

var str = 'test_23';
alert(str.substring('test_'.length));

Quotes!

if [ "$1" != -v ]; then

Otherwise, when $1 is completely empty, your test becomes:

[ != -v ]

instead of

[ "" != -v ]

...and != is not a unary operator (that is, one capable of taking only a single argument).

Here's a question and answer for this: Difference between screen.availHeight and window.height()

Has pics too, so you can actually see the differences. Hope this helps.

Basically, $(window).height() give you the maximum height inside of the browser window (viewport), and$(document).height() gives you the height of the document inside of the browser. Most of the time, they will be exactly the same, even with scrollbars.

Because you're not specifying a precision and a rounding-mode. BigDecimal is complaining that it could use 10, 20, 5000, or infinity decimal places, and it still wouldn't be able to give you an exact representation of the number. So instead of giving you an incorrect BigDecimal, it just whinges at you.

However, if you supply a RoundingMode and a precision, then it will be able to convert (eg. 1.333333333-to-infinity to something like 1.3333 ... but you as the programmer need to tell it what precision you're 'happy with'.

In Django 1.8, this is how I did mine.

from django.views.generic.base import RedirectView

url(r'^$', views.comingSoon, name='homepage'),
# whatever urls you might have in here
# make sure the 'catch-all' url is placed last
url(r'^.*$', RedirectView.as_view(pattern_name='homepage', permanent=False))

Instead of using url, you can use the pattern_name, which is a bit un-DRY, and will ensure you change your url, you don't have to change the redirect too.

In sequelize you can easily add order by clauses.

exports.getStaticCompanies = function () {
    return Company.findAll({
        where: {
            id: [46128, 2865, 49569,  1488,   45600,   61991,  1418,  61919,   53326,   61680]
        }, 
        // Add order conditions here....
        order: [
            ['id', 'DESC'],
            ['name', 'ASC'],
        ],
        attributes: ['id', 'logo_version', 'logo_content_type', 'name', 'updated_at']
    });
};

See how I've added the order array of objects?

order: [
      ['COLUMN_NAME_EXAMPLE', 'ASC'], // Sorts by COLUMN_NAME_EXAMPLE in ascending order
],

Edit:

You might have to order the objects once they've been recieved inside the .then() promise. Checkout this question about ordering an array of objects based on a custom order:

How do I sort an array of objects based on the ordering of another array?

It actually tells you what's wrong, but you ignored it because you didn't check the error returned from json.Marshal.

json: unsupported type: map[int]main.Foo

JSON spec doesn't support anything except strings for object keys, while javascript won't be fussy about it, it's still illegal.

You have two options:

1 Use map[string]Foo and convert the index to string (using fmt.Sprint for example):

datas := make(map[string]Foo, N)

for i := 0; i < 10; i++ {
    datas[fmt.Sprint(i)] = Foo{Number: 1, Title: "test"}
}
j, err := json.Marshal(datas)
fmt.Println(string(j), err)

2 Simply just use a slice (javascript array):

datas2 := make([]Foo, N)
for i := 0; i < 10; i++ {
    datas2[i] = Foo{Number: 1, Title: "test"}
}
j, err = json.Marshal(datas2)
fmt.Println(string(j), err)

Solution 1: cast

String temp=(String)data.getParameterValue("request");

Solution 2: use typed map:

Map<String, String> param;

So you change Change the return type of your function

public String getParameterValue(String key)
{
    if(params.containsKey(key))
    {
        return params.get(key);
    }
    return null;
}

and then no need for cast or toString

String temp=data.getParameterValue("request");

Specify the Class Card for the constructor-:

void Card::Card(Card::Rank rank, Card::Suit suit) {

And also define the default constructor and destructor.

Seconds since epoch to datetime to strftime:

>>> ts_epoch = 1362301382
>>> ts = datetime.datetime.fromtimestamp(ts_epoch).strftime('%Y-%m-%d %H:%M:%S')
>>> ts
'2013-03-03 01:03:02'

Better variant to generate SQL script by SQL request. It will not ruin defaults/nulls.

SELECT concat
    (
        'ALTER TABLE ', 
            t1.TABLE_SCHEMA, 
            '.', 
            t1.table_name, 
            ' MODIFY ', 
            t1.column_name, 
            ' ', 
            t1.column_type,
            ' CHARACTER SET utf8 COLLATE utf8_general_ci',
            if(t1.is_nullable='YES', ' NULL', ' NOT NULL'),
            if(t1.column_default is not null, concat(' DEFAULT \'', t1.column_default, '\''), ''),
            ';'
    )
from 
    information_schema.columns t1
where 
    t1.TABLE_SCHEMA like 'your_table_here' AND
    t1.COLLATION_NAME IS NOT NULL AND
    t1.COLLATION_NAME NOT IN ('utf8_general_ci');

obj is an array in your example.

fs.writeFileSync(filename, data, [options]) requires either String or Buffer in the data parameter. see docs.

Try to write the array in a string format:

// writes 'https://twitter.com/#!/101Cookbooks', 'http://www.facebook.com/101cookbooks'
fs.writeFileSync('./data.json', obj.join(',') , 'utf-8'); 

Or:

// writes ['https://twitter.com/#!/101Cookbooks', 'http://www.facebook.com/101cookbooks']
var util = require('util');
fs.writeFileSync('./data.json', util.inspect(obj) , 'utf-8');

edit: The reason you see the array in your example is because node's implementation of console.log doesn't just call toString, it calls util.format see console.js source

What I want to say here is like some kind of add-on on @Suciu Lucian's answer.

The weird situation I ran into is that when I apply the solution of @Suciu Lucian in my file, it works in Chrome but not in Safari (and did not try in Firefox). After I studied the guide of styling table border published by w3.org, I found something alternative:

table.myTable{
  border-spacing: 0;
}

table.myTable td{
  border-bottom:1px solid red;
}

Yes you have to style the td instead of the tr.

You can't do it like that. The join clause (and the Join() extension method) supports only equijoins. That's also the reason, why it uses equals and not ==. And even if you could do something like that, it wouldn't work, because join is an inner join, not outer join.

From PHP 7 with null coalescing operator it will be shorter:

$is_ajax = 'xmlhttprequest' == strtolower( $_SERVER['HTTP_X_REQUESTED_WITH'] ?? '' );

You can rewrite the code likes this:

#include<iostream>
#include<stdio.h>

using namespace std;

This can be done without the use of hidden field. You have to take benefit of the JQuerys ability to make custom attributes on run time.

('#selector').autocomplete({
    source: url,
    select: function (event, ui) {
        $("#txtAllowSearch").val(ui.item.label); // display the selected text
        $("#txtAllowSearch").attr('item_id',ui.item.value); // save selected id to hidden input
    }
});

$('#button').click(function() {
    alert($("#txtAllowSearch").attr('item_id')); // get the id from the hidden input
}); 

If your DIV tag is immediately followed by the IMG tag, you can also use:

$(this).next();

While the other answers are right, I prefer this way:

function ascii (a) { return a.charCodeAt(0); }

Then, to use it, simply:

var lineBreak = ascii("\n");

I am using this for a small shortcut system:

$(window).keypress(function(event) {
  if (event.ctrlKey && event.which == ascii("s")) {
    savecontent();
    }
  // ...
  });

And you can even use it inside map() or other methods:

var ints = 'ergtrer'.split('').map(ascii);

I found a simple way

    TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
    SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);
    CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);

    RestTemplate restTemplate = new RestTemplate(requestFactory);

Using only the standard library with minimal code!

thread {
    val jsonStr = try { URL(url).readText() } catch (ex: Exception) { return@thread }
    runOnUiThread { displayOrWhatever(jsonStr) }
}

This starts a GET request on a new thread, leaving the UI thread to respond to user input. However, we can only modify UI elements from the main/UI thread, so we actually need a runOnUiThread block to show the result to our user. This enqueues our display code to be run on the UI thread soon.

The try/catch is there so your app won't crash if you make a request with your phone's internet off. Add your own error handling (e.g. showing a Toast) as you please.

.readText() is not part of the java.net.URL class but a Kotlin extension method, Kotlin "glues" this method onto URL. This is enough for plain GET requests, but for more control and POST requests you need something like the Fuel library.

Do you mean can you select them? If so, then yes:

$(":checkbox[myattr]")

Old question but worth adding an answer if using .NET Core 3.0 or later. JSON serialization/deserialization is built into the framework (System.Text.Json), so you don't have to use third party libraries any more. Here's an example based off the top answer given by @Icarus

using System;
using System.Collections.Generic;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var json = "[{\"Name\":\"John Smith\", \"Age\":35}, {\"Name\":\"Pablo Perez\", \"Age\":34}]";

            // use the built in Json deserializer to convert the string to a list of Person objects
            var people = System.Text.Json.JsonSerializer.Deserialize<List<Person>>(json);

            foreach (var person in people)
            {
                Console.WriteLine(person.Name + " is " + person.Age + " years old.");
            }
        }

        public class Person
        {
            public int Age { get; set; }
            public string Name { get; set; }
        }
    }
}

This worked for me very well. And it doesn't reload the bundle everytime. I tried to take some stats to load and reload the bundle from external file location.

File file = new File("C:\\temp");
URL[] urls = {file.toURI().toURL()};
ClassLoader loader = new URLClassLoader(urls);
ResourceBundle rb = ResourceBundle.getBundle("myResource", Locale.getDefault(), loader);

where "c:\temp" is the external folder (NOT on the classpath) holding the property files, and "myResource" relates to myResource.properties, myResource_fr_FR.properties, etc.

Note: If you have the same bundle name on your classpath then it will be picked up by default using this constructor of URLClassLoader.

Find some of the stats below, all time in ms. I am not worried about the initial load time as that could be something with my workspace or code that I am trying to figure out but what I am trying to show is the reload took way lesser telling me its coming from memory.

Here some of the stats:

• Initial Locale_1 load took 3486
• Reload Locale_1 took 24
• Reload Locale_1 took 23
• Reload Locale_1 took 22
• Reload Locale_1 took 15
• Initial Locale_2 load took 870
• Reload Locale_2 took 22
• Reload Locale_2 took 18
• Initial Locale_3 load took 2298
• Reload Locale_3 took 8
• Reload Locale_3 took 4

Here's a possibile solution (in Python):

Let's say you have a notebook with a file name, call it Notebook.ipynb. You are currently working in that notebook, and want to access other folders and files around it. Here's it's path:

import os
notebook_path = os.path.abspath("Notebook.ipynb")

In other words, just use the os module, and get the absolute path of your notebook (it's a file, too!). From there, use the os module and your path to navigate.

For example, if your train.csv is in a folder called 'Datasets', and the notebook is sitting right next to that folder, you could get the data like this:

train_csv = os.path.join(os.path.dirname(notebook_path), "Datasets/train.csv")
with open(train_csv) as file:
    #....etc

The takeaway is that the notebook has a file name, and as long as your language supports pathname manipulations (e.g. the os module in Python) you can likely use the notebook filename.

Lastly, the reason your code fails is probably because you're either trying to access local files (like your Mac's 'Downloads' folder) when you're working in an online Notebook (like Kaggle, which hosts your environment for you, online and away from your Mac), or you moved or deleted something in that path. This is what the os module in Python is meant to do; it will find the file's path whether it's on your Mac or in a Kaggle server.

Add the following to package.json:

  "engines": {
    "node": ">=10.0.0",
    "npm": ">=6.0.0"
  },

Add the following to .npmrc (same directory as package.json):

engine-strict=true

Reading through all contributions, it looks like many different origins exhibit cause this same problem symptoms.

In my case for instance - I got this problem as soon as I added

android:progressBackgroundTintMode="src_over"

to my progress bar properties. I think the GUI designer of ADT is known for several bugs. Hence I assume this is one of them. So if you encounter similar problem symptoms (that just do not make sense) after playing with your GUI setup, just try to roll back what you did and undo your last GUI modifications.

Just press Ctrl+z with the recently modified file on screen.

Or:

The Version Control tool could be helpful. Open the Version Control panel - choose Local Changes tab and see recently modified (perhaps .xml) files.

Right click some most suspicious one and click Show Diff. Then just guess which modified line could be responsible.

Good luck :)

You can do this with LibreOffice:

libreoffice --headless --convert-to csv $filename --outdir $outdir

For reasons not clear to me, you might need to run this with sudo. You can make LibreOffice work with sudo without requiring a password by adding this line to you sudoers file:

users ALL=(ALL) NOPASSWD: libreoffice

While in insert mode hit CTRL-R {register}

Examples:

• CTRL-R * will insert in the contents of the clipboard
• CTRL-R " (the unnamed register) inserts the last delete or yank.

To find this in vim's help type :h i_ctrl-r

In VB.NET, but it's the same in C#:

Dim x As New TimeSpan(0, 0, 80)
debug.print(x.ToString())
' Will print 00:01:20

Other Way is:

String[] parts = selectedFilePath.split("/");
    final String fileName = parts[parts.length-1];

I used the script provided by Matt (2008-10-02). The only thing I had trouble with was that it wouldn't delete the search.log file. I expect because I had to cd to another location to start my program. I cd'd back to where the BAT file and search.log are, but it still wouldn't delete. So I resolved that by deleting the search.log file first instead of last.

del search.log

tasklist /FI "IMAGENAME eq myprog.exe" /FO CSV > search.log

FOR /F %%A IN (search.log) DO IF %%-zA EQU 0 GOTO end

cd "C:\Program Files\MyLoc\bin"

myprog.exe myuser mypwd

:end

Looks like "+x" causes problems:

root@raspi1:~# cat > /tmp/btest
#!/bin/bash

jobname="job_201312161447_0003"
jobname_pre=${jobname:0:16}
jobname_post=${jobname:17}
root@raspi1:~# chmod +x /tmp/btest
root@raspi1:~# /tmp/btest
root@raspi1:~# sh -x /tmp/btest
+ jobname=job_201312161447_0003
/tmp/btest: 4: /tmp/btest: Bad substitution

An easier way to accomplish this is to go to: Open Module Settings (your project) > Project > Gradle version and enter 2.10

Pythont 3.5 added the methods run() and call() to the subprocess module, both returning a CompletedProcess object. With this you are fine using proc.stdout.splitlines():

proc = subprocess.run( comman, shell=True, capture_output=True, text=True, check=True )
for line in proc.stdout.splitlines():
   print "stdout:", line

Use the Find method if item_manuf_id is a primary key:

var result = dtPs.Rows.Find("some value");

If you only want to know if the value is in there then use the Contains method.

if (dtPs.Rows.Contains("some value"))
{
  ...
}

Primary key restriction applies to Contains aswell.

I usually have it on a Makefile:

# All .js compiled into a single one.
compiled=./path/of/js/main.js

compile:
    @find ./path/of/js -type f -name "*.js" | xargs cat > $(compiled)

Then you run:

make compile

I hope it helps.

For node.js I've found the following to be effective way to wait for an element to no longer be present:

// variable to hold loop limit
    var limit = 5;
// variable to hold the loop count
    var tries = 0;
        var retry = driver.findElements(By.xpath(selector));
            while(retry.size > 0 && tries < limit){
                driver.sleep(timeout / 10)
                tries++;
                retry = driver.findElements(By.xpath(selector))
            }

PHP works only on server side, not on user host. Use JavaScript or jQuery to get this info and send via AJAX or URL (?x=1024&y=640).

In my case I was using the WebBrowser control (forcing IE 11) and I could not get past the error. Switching to CefSharp which uses Chrome solved it for me.

Use CURRENT_TIMESTAMP (or GETDATE() on archaic versions of SQL Server).

In case someone else stumbles onto this topic - here's a more "one size fits all" solution.

If you are using .git or .svn, you can use the --exclude-vcs option for tar. This will ignore many different files/folders required by different version control systems.

If you want to read more about it, check out: http://www.gnu.org/software/tar/manual/html_section/exclude.html

I would make the class final and every method would be static.

So the class cannot be extended and the methods can be called by Classname.methodName. If you add members, be sure that they work thread safe ;)

While the answers provided here work properly, I wanted something a bit more 'straightforward', I found it here: link First enter rails console:

$rails console

Then just type:

ActiveRecord::Migration.drop_table(:table_name)

And done, worked for me!

Ok, I solved it by adding the url for the background image at the end of the line.

It is also very important to distinguish a SENDING multicast socket from a RECEIVING multicast socket.

I agree with all the answers above regarding RECEIVING multicast sockets. The OP noted that binding a RECEIVING socket to an interface did not help. However, it is necessary to bind a multicast SENDING socket to an interface.

For a SENDING multicast socket on a multi-homed server, it is very important to create a separate socket for each interface you want to send to. A bound SENDING socket should be created for each interface.

  // This is a fix for that bug that causes Servers to pop offline/online.
  // Servers will intermittently pop offline/online for 10 seconds or so.
  // The bug only happens if the machine had a DHCP gateway, and the gateway is no longer accessible.
  // After several minutes, the route to the DHCP gateway may timeout, at which
  // point the pingponging stops.
  // You need 3 machines, Client machine, server A, and server B
  // Client has both ethernets connected, and both ethernets receiving CITP pings (machine A pinging to en0, machine B pinging to en1)
  // Now turn off the ping from machine B (en1), but leave the network connected.
  // You will notice that the machine transmitting on the interface with
  // the DHCP gateway will fail sendto() with errno 'No route to host'
  if ( theErr == 0 )
  {
     // inspired by 'ping -b' option in man page:      
     //      -b boundif
     //             Bind the socket to interface boundif for sending.
     struct sockaddr_in bindInterfaceAddr;
     bzero(&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     bindInterfaceAddr.sin_len = sizeof(bindInterfaceAddr);
     bindInterfaceAddr.sin_family = AF_INET;
     bindInterfaceAddr.sin_addr.s_addr = htonl(interfaceipaddr);
     bindInterfaceAddr.sin_port = 0; // Allow the kernel to choose a random port number by passing in 0 for the port.
     theErr = bind(mSendSocketID, (struct sockaddr *)&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     struct sockaddr_in serverAddress;
     int namelen = sizeof(serverAddress);  
     if (getsockname(mSendSocketID, (struct sockaddr *)&serverAddress, (socklen_t *)&namelen) < 0) {
        DLogErr(@"ERROR Publishing service... getsockname err");
     }
     else
     {
        DLog( @"socket %d bind, %@ port %d", mSendSocketID, [NSString stringFromIPAddress:htonl(serverAddress.sin_addr.s_addr)], htons(serverAddress.sin_port) );
     }

Without this fix, multicast sending will intermittently get sendto() errno 'No route to host'. If anyone can shed light on why unplugging a DHCP gateway causes Mac OS X multicast SENDING sockets to get confused, I would love to hear it.

The scroll speed CAN be changed, adjusted, reversed, all of the above - via javascript (or a js library such as jQuery).

WHY would you want to do this? Parallax is just one of the reasons. I have no idea why anyone would argue against doing so -- the same negative arguments can be made against hiding DIVs, sliding elements up/down, etc. Websites are always a combination of technical functionality and UX design -- a good designer can use almost any technical capability to improve UX. That is what makes him/her good.

Toni Almeida of Portugal created a brilliant demo, reproduced below:

jsFiddle Demo

HTML:

<div id="myDiv">
    Use the mouse wheel (not the scroll bar) to scroll this DIV. You will see that the scroll eventually slows down, and then stops. <span class="boldit">Use the mouse wheel (not the scroll bar) to scroll this DIV. You will see that the scroll eventually slows down, and then stops. </span>
</div>

javascript/jQuery:

  function wheel(event) {
      var delta = 0;
      if (event.wheelDelta) {(delta = event.wheelDelta / 120);}
      else if (event.detail) {(delta = -event.detail / 3);}

      handle(delta);
      if (event.preventDefault) {(event.preventDefault());}
      event.returnValue = false;
  }

  function handle(delta) {
      var time = 1000;
      var distance = 300;

      $('html, body').stop().animate({
          scrollTop: $(window).scrollTop() - (distance * delta)
      }, time );
  }

  if (window.addEventListener) {window.addEventListener('DOMMouseScroll', wheel, false);}
    window.onmousewheel = document.onmousewheel = wheel;

Built a modal popup example using syarul's jsFiddle link. Here is the updated fiddle.

Created an angular directive called modal and used in html. Explanation:-

HTML

<div ng-controller="MainCtrl" class="container">
  <button ng-click="toggleModal('Success')" class="btn btn-default">Success</button>
  <button ng-click="toggleModal('Remove')" class="btn btn-default">Remove</button>
  <button ng-click="toggleModal('Deny')" class="btn btn-default">Deny</button>
  <button ng-click="toggleModal('Cancel')" class="btn btn-default">Cancel</button>
  <modal visible="showModal">
      Any additional data / buttons
  </modal>
</div>

On button click toggleModal() function is called with the button message as parameter. This function toggles the visibility of popup. Any tags that you put inside will show up in the popup as content since ng-transclude is placed on modal-body in the directive template.

JS

var mymodal = angular.module('mymodal', []);

mymodal.controller('MainCtrl', function ($scope) {
    $scope.showModal = false;
    $scope.buttonClicked = "";
    $scope.toggleModal = function(btnClicked){
        $scope.buttonClicked = btnClicked;
        $scope.showModal = !$scope.showModal;
    };
  });

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' + 
              '<div class="modal-header">' + 
                '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>' + 
                '<h4 class="modal-title">{{ buttonClicked }} clicked!!</h4>' + 
              '</div>' + 
              '<div class="modal-body" ng-transclude></div>' + 
            '</div>' + 
          '</div>' + 
        '</div>',
      restrict: 'E',
      transclude: true,
      replace:true,
      scope:true,
      link: function postLink(scope, element, attrs) {
        scope.title = attrs.title;

        scope.$watch(attrs.visible, function(value){
          if(value == true)
            $(element).modal('show');
          else
            $(element).modal('hide');
        });

        $(element).on('shown.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = true;
          });
        });

        $(element).on('hidden.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = false;
          });
        });
      }
    };
  });

<div class="modal">

Once an instance has been started, there is no way to change the keypair associated with the instance at a meta data level, but you can change what ssh key you use to connect to the instance.

There is a startup process on most AMIs that downloads the public ssh key and installs it in a .ssh/authorized_keys file so that you can ssh in as that user using the corresponding private ssh key.

If you want to change what ssh key you use to access an instance, you will want to edit the authorized_keys file on the instance itself and convert to your new ssh public key.

The authorized_keys file is under the .ssh subdirectory under the home directory of the user you are logging in as. Depending on the AMI you are running, it might be in one of:

/home/ec2-user/.ssh/authorized_keys
/home/ubuntu/.ssh/authorized_keys
/root/.ssh/authorized_keys

After editing an authorized_keys file, always use a different terminal to confirm that you are able to ssh in to the instance before you disconnect from the session you are using to edit the file. You don't want to make a mistake and lock yourself out of the instance entirely.

While you're thinking about ssh keypairs on EC2, I recommend uploading your own personal ssh public key to EC2 instead of having Amazon generate the keypair for you.

Here's an article I wrote about this:

Uploading Personal ssh Keys to Amazon EC2
http://alestic.com/2010/10/ec2-ssh-keys

This would only apply to new instances you run.

You can unset session variable using:

1. session_unset - Frees all session variables (It is equal to using: $_SESSION = array(); for older deprecated code)
2. unset($_SESSION['Products']); - Unset only Products index in session variable. (Remember: You have to use like a function, not as you used)
3. session_destroy — Destroys all data registered to a session

To know the difference between using session_unset and session_destroy, read this SO answer. That helps.

Above solution given by @Shailesh Rohit works perfectly fine. Some tricks has to be done.

1. If you are putting helper class inside the same class( main class) then make Helper class as static and getListViewSize() not be static.

2. Most important, write "Helper.getListViewSize(listView);" statement after setting adapter for the first time like "listView.setAdapter(myAdapter);" as well as when ever you are using "myAdapter.notifyDataSetChanged();"

3. Usage is shown below.

   listView = (ListView) findViewById(R.id.listView); myAdapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1, listValues); listView .setAdapter(myAdapter); Helper.getListViewSizelistView(listView);

   myAdapter.notifyDataSetChanged(); Helper.getListViewSizelistView(listView);

SCREEN:

NOTE: screen is actually not able to send hex, as far as I know. To do that, use echo or printf

I was using the suggestions in this post to write to a serial port, then using the info from another post to read from the port, with mixed results. I found that using screen is an "easier" solution, since it opens a terminal session directly with that port. (I put easier in quotes, because screen has a really weird interface, IMO, and takes some further reading to figure it out.)

You can issue this command to open a screen session, then anything you type will be sent to the port, plus the return values will be printed below it:

screen /dev/ttyS0 19200,cs8

(Change the above to fit your needs for speed, parity, stop bits, etc.) I realize screen isn't the "linux command line" as the post specifically asks for, but I think it's in the same spirit. Plus, you don't have to type echo and quotes every time.

ECHO:

Follow praetorian droid's answer. HOWEVER, this didn't work for me until I also used the cat command (cat < /dev/ttyS0) while I was sending the echo command.

PRINTF:

I found that one can also use printf's '%x' command:

c="\x"$(printf '%x' 0x12)
printf $c >> $SERIAL_COMM_PORT

Again, for printf, start cat < /dev/ttyS0 before sending the command.

You can make your TextBox as customed PasswordBox by simply adding the following value to FontFamily property of your TextBox control.

<TextBox
    Text="{Binding Password}"
    FontFamily="ms-appx:///Assets/PassDot.ttf#PassDot"
    FontSize="35"/>

In my case this works perfectly. This will show dot in place of the actual text (not star(*) though).

Yes. You need to close the resultset, the statement and the connection. If the connection has come from a pool, closing it actually sends it back to the pool for reuse.

You typically have to do this in a finally{} block, such that if an exception is thrown, you still get the chance to close this.

Many frameworks will look after this resource allocation/deallocation issue for you. e.g. Spring's JdbcTemplate. Apache DbUtils has methods to look after closing the resultset/statement/connection whether null or not (and catching exceptions upon closing), which may also help.

Don't use list as a variable name for it shadows the builtin.

And there is no need to determine the length of the list. Just iterate over it.

def printer(data):
    for element in data:
        print(element[0])

Just an addendum: Looking at the contents of the inner lists I think they might be the wrong data structure. It looks like you want to use a dictionary instead.

You should be able to split your string pretty easily, like so:

aString.Split(Environment.NewLine.ToCharArray());

Also try to dos2unix the shell script, because sometimes it has Windows line endings and the shell does not recognize it.

$ dos2unix MigrateNshell.sh

This helps sometimes.

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

If you are using Sass in a Rails project, the sass-rails gem, https://github.com/rails/sass-rails, features glob importing.

@import "foo/*"     // import all the files in the foo folder
@import "bar/**/*"  // import all the files in the bar tree

To answer the concern in another answer "If you import a directory, how can you determine import order? There's no way that doesn't introduce some new level of complexity."

Some would argue that organizing your files into directories can REDUCE complexity.

My organization's project is a rather complex app. There are 119 Sass files in 17 directories. These correspond roughly to our views and are mainly used for adjustments, with the heavy lifting being handled by our custom framework. To me, a few lines of imported directories is a tad less complex than 119 lines of imported filenames.

To address load order, we place files that need to load first – mixins, variables, etc. — in an early-loading directory. Otherwise, load order is and should be irrelevant... if we are doing things properly.

I think this should help you.

Tell me if it works.

P/s: here is some media query for standard devices. http://css-tricks.com/snippets/css/media-queries-for-standard-devices/

If you want a separate .js file to better organize your routes, just create a variable in the app.js file pointing to its location in the filesystem:

var wf = require(./routes/wf);

then,

app.get('/wf', wf.foo );

where .foo is some function declared in your wf.js file. e.g

// wf.js file 
exports.foo = function(req,res){

          console.log(` request object is ${req}, response object is ${res} `);

}

Undoing a merge with git is so easy you shouldn't even worry about the dry run:

$ git pull $REMOTE $BRANCH
# uh oh, that wasn't right
$ git reset --hard ORIG_HEAD
# all is right with the world

EDIT: As noted in the comments below, if you have changes in your working directory or staging area you'll probably want to stash them before doing the above (otherwise they will disappear following the git reset above)

Is there any way we could use this method to delete duplicates in a table? The result set is basically a collection of unique records, so if we could delete all records not in the result set, we would effectively have no duplicates? I tried this but mySQL gave a 1093 error.

DELETE FROM messages WHERE id NOT IN
 (SELECT m1.id  
 FROM messages m1 LEFT JOIN messages m2  
 ON (m1.name = m2.name AND m1.id < m2.id)  
 WHERE m2.id IS NULL)

Is there a way to maybe save the output to a temp variable then delete from NOT IN (temp variable)? @Bill thanks for a very useful solution.

EDIT: Think i found the solution:

DROP TABLE IF EXISTS UniqueIDs; 
CREATE Temporary table UniqueIDs (id Int(11)); 

INSERT INTO UniqueIDs 
    (SELECT T1.ID FROM Table T1 LEFT JOIN Table T2 ON 
    (T1.Field1 = T2.Field1 AND T1.Field2 = T2.Field2 #Comparison Fields  
    AND T1.ID < T2.ID) 
    WHERE T2.ID IS NULL); 

DELETE FROM Table WHERE id NOT IN (SELECT ID FROM UniqueIDs);

subprocess.Popen() is strict super-set of os.system().

It's not an array of arrays. It's an observable of observable(s).

The following returns an observable stream of string.

requestStream
  .map(function(requestUrl) {
    return requestUrl;
  });

While this returns an observable stream of observable stream of json

requestStream
  .map(function(requestUrl) {
    return Rx.Observable.fromPromise(jQuery.getJSON(requestUrl));
  });

flatMap flattens the observable automatically for us so we can observe the json stream directly

You can get it by XMLHttpRequest.responseText in XMLHttpRequest.onreadystatechange when XMLHttpRequest.readyState equals to XMLHttpRequest.DONE.

Here's an example (not compatible with IE6/7).

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState == XMLHttpRequest.DONE) {
        alert(xhr.responseText);
    }
}
xhr.open('GET', 'http://example.com', true);
xhr.send(null);

For better crossbrowser compatibility, not only with IE6/7, but also to cover some browser-specific memory leaks or bugs, and also for less verbosity with firing ajaxical requests, you could use jQuery.

$.get('http://example.com', function(responseText) {
    alert(responseText);
});

Note that you've to take the Same origin policy for JavaScript into account when not running at localhost. You may want to consider to create a proxy script at your domain.

With C++17 you can use std::filesystem::is_directory function (https://en.cppreference.com/w/cpp/filesystem/is_directory). It accepts a std::filesystem::path object which can be constructed with a unicode path.

Grab the VLC Python module, vlc.py, which provides full support for libVLC and pop that in site-packages. Then:

>>> import vlc
>>> p = vlc.MediaPlayer("file:///path/to/track.mp3")
>>> p.play()

And you can stop it with:

>>> p.stop()

That module offers plenty beyond that (like pretty much anything the VLC media player can do), but that's the simplest and most effective means of playing one MP3.

You could play with os.path a bit to get it to find the path to the MP3 for you, given the filename and possibly limiting the search directories.

Full documentation and pre-prepared modules are available here. Current versions are Python 3 compatible.

From man githooks:

pre-commit
This hook is invoked by git commit, and can be bypassed with --no-verify option. It takes no parameter, and is invoked before obtaining the proposed commit log message and making a commit. Exiting with non-zero status from this script causes the git commit to abort.

There are workarounds but no clean/short/sweet way to do it with streams and to be honest, you would probably be better off with:

int idx = 0;
for (Param p : params) query.bind(idx++, p);

Or the older style:

for (int idx = 0; idx < params.size(); idx++) query.bind(idx, params.get(idx));

If you're recompiling a disassembled APK with APK tool:

Just Set Memory Allocation a little bigger

set switch -Xmx1024mto -Xmx2048m

java -Xmx2048m -jar signapk.jar -w testkey.x509.pem testkey.pk8 "%APKOUT%" "%SIGNED%"

you're good to go.. :)

Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.

For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

If you are using TortoiseSVN, right-click on a file and then select TortoiseSVN / Add to ignore list. This will add the file/wildcard to the svn:ignore property.

svn:ignore will be checked when you are checking in files, and matching files will be ignored. I have the following ignore list for a Visual Studio .NET project:

bin obj
*.exe
*.dll
_ReSharper
*.pdb
*.suo

You can find this list in the context menu at TortoiseSVN / Properties.

Here is an option at the bottom of the Custom Search Control Panel: "Sites to search", you can choose "Search the entire web but emphasize included sites"

You can use the following time conversion within SQL like this:

--Convert Time to Integer (Minutes)
DECLARE @timeNow datetime = '14:47'
SELECT DATEDIFF(mi,CONVERT(datetime,'00:00',108), CONVERT(datetime, RIGHT(CONVERT(varchar, @timeNow, 100),7),108))

--Convert Minutes to Time
DECLARE @intTime int = (SELECT DATEDIFF(mi,CONVERT(datetime,'00:00',108), CONVERT(datetime, RIGHT(CONVERT(varchar, @timeNow, 100),7),108)))
SELECT DATEADD(minute, @intTime, '')

Result: 887 <- Time in minutes and 1900-01-01 14:47:00.000 <-- Minutes to time

As of release 1.7 Dashboard supports user authentication based on:

• Authorization: Bearer <token> header passed in every request to Dashboard. Supported from release 1.6. Has the highest priority. If present, login view will not be shown.
• Bearer Token that can be used on Dashboard login view.
• Username/password that can be used on Dashboard login view.
• Kubeconfig file that can be used on Dashboard login view.

— Dashboard on Github

Token

Here Token can be Static Token, Service Account Token, OpenID Connect Token from Kubernetes Authenticating, but not the kubeadm Bootstrap Token.

With kubectl, we can get an service account (eg. deployment controller) created in kubernetes by default.

$ kubectl -n kube-system get secret
# All secrets with type 'kubernetes.io/service-account-token' will allow to log in.
# Note that they have different privileges.
NAME                                     TYPE                                  DATA      AGE

Kubeconfig

The dashboard needs the user in the kubeconfig file to have either username & password or token, but admin.conf only has client-certificate. You can edit the config file to add the token that was extracted using the method above.

$ kubectl config set-credentials cluster-admin --token=bearer_token

Alternative (Not recommended for Production)

Here are two ways to bypass the authentication, but use for caution.

Deploy dashboard with HTTP

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/alternative/kubernetes-dashboard.yaml

Dashboard can be loaded at http://localhost:8001/ui with kubectl proxy.

Granting admin privileges to Dashboard's Service Account

$ cat <<EOF | kubectl create -f -
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: kubernetes-dashboard
  labels:
    k8s-app: kubernetes-dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: kubernetes-dashboard
  namespace: kube-system
EOF

Afterwards you can use Skip option on login page to access Dashboard.

If you are using dashboard version v1.10.1 or later, you must also add --enable-skip-login to the deployment's command line arguments. You can do so by adding it to the args in kubectl edit deployment/kubernetes-dashboard --namespace=kube-system.

Example:

      containers:
      - args:
        - --auto-generate-certificates
        - --enable-skip-login            # <-- add this line
        image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1

do like this simply: (as said in comment here is with example with two methods)

import {Component} from 'angular2/core';

@Component({
    selector: 'my-app', 
    template: `
      <button (click)="checkEvent($event,'a')" id="abc" class="def">Display Toastr</button>
      <button (click)="checkEvent($event,'b')" id="abc1" class="def1">Display Toastr1</button>
    `
})
export class AppComponent {
  checkEvent(event, id){
    console.log(event, id, event.srcElement.attributes.id);
  }
}

You can use the environment variable NUMBER_OF_PROCESSORS for the total number of processors:

echo %NUMBER_OF_PROCESSORS%

Using regular expressions, you can represent any whitespace character with the metacharacter "\s"

MSDN Reference

Depending on your needs, you have a few options here.

If you don't need to do key/value lookups and want to stick with a List<>, you can make use of Tuple<int, string>:

List<Tuple<int, string>> mylist = new List<Tuple<int, string>>();

// add an item
mylist.Add(new Tuple<int, string>(someInt, someString));

If you do want key/value lookups, you could move towards a Dictionary<int, string>:

Dictionary<int, string> mydict = new Dictionary<int, string>();

// add an item
mydict.Add(someInt, someString);

FWIW, sp_test will not be returning anything but an integer (all SQL Server stored procs just return an integer) and no result sets on the wire (since no SELECT statements). To get the output of the PRINT statements, you normally use the InfoMessage event on the connection (not the command) in ADO.NET.

Interestingly, the HttpWebResponse.GetResponseStream() that you get from the WebException.Response is not the same as the response stream that you would have received from server. In our environment, we're losing actual server responses when a 400 HTTP status code is returned back to the client using the HttpWebRequest/HttpWebResponse objects. From what we've seen, the response stream associated with the WebException's HttpWebResponse is generated at the client and does not include any of the response body from the server. Very frustrating, as we want to message back to the client the reason for the bad request.

On the following option:

WebElement option = select.getFirstSelectedOption();
option.getText();

If from the method getText() you get a blank, you can get the string from the value of the option using the method getAttribute:

WebElement option = select.getFirstSelectedOption();
option.getAttribute("value");

There are two main ways that you can do this. One of them is the standard CakePHP way, and the other is using a custom join.

It's worth pointing out that this advice is for CakePHP 2.x, not 3.x.

The CakePHP Way

You would create a relationship with your User model and Messages Model, and use the containable behavior:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array('Message');
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array('User');
}

You need to change the messages.from column to be messages.user_id so that cake can automagically associate the records for you.

Then you can do this from the messages controller:

$this->Message->find('all', array(
    'contain' => array('User')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The (other) CakePHP way

I recommend using the first method, because it will save you a lot of time and work. The first method also does the groundwork of setting up a relationship which can be used for any number of other find calls and conditions besides the one you need now. However, cakePHP does support a syntax for defining your own joins. It would be done like this, from the MessagesController:

$this->Message->find('all', array(
    'joins' => array(
        array(
            'table' => 'users',
            'alias' => 'UserJoin',
            'type' => 'INNER',
            'conditions' => array(
                'UserJoin.id = Message.from'
            )
        )
    ),
    'conditions' => array(
        'Message.to' => 4
    ),
    'fields' => array('UserJoin.*', 'Message.*'),
    'order' => 'Message.datetime DESC'
));

Note, I've left the field name messages.from the same as your current table in this example.

Using two relationships to the same model

Here is how you can do the first example using two relationships to the same model:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array(
        'MessagesSent' => array(
            'className'  => 'Message',
            'foreignKey' => 'from'
         )
    );
    public $belongsTo = array(
        'MessagesReceived' => array(
            'className'  => 'Message',
            'foreignKey' => 'to'
         )
    );
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array(
        'UserFrom' => array(
            'className'  => 'User',
            'foreignKey' => 'from'
        )
    );
    public $hasMany = array(
        'UserTo' => array(
            'className'  => 'User',
            'foreignKey' => 'to'
        )
    );
}

Now you can do your find call like this:

$this->Message->find('all', array(
    'contain' => array('UserFrom')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The major difference between Page_Load and Page_PreRender is that in the Page_Load method not all of your page controls are completely initialized (loaded), because individual controls Load() methods has not been called yet. This means that tree is not ready for rendering yet. In Page_PreRender you guaranteed that all page controls are loaded and ready for rendering. Technically Page_PreRender is your last chance to tweak the page before it turns into HTML stream.

1. Simply Download the PHP version that you want from this url: http://wampserver.aviatechno.net/
2. Goto your wamp\bin\php directory and extract it like this(Note: you need to rename your folder to phpversionOfPhp
3. Start wamp and click wamp icon and choose the version of php you want to use: https://gyazo.com/de5727d7e254795e238422783dec3758

If, like me, you are still using the browser version (which will be deprecated soon), have you tried the "Code" button?

This should generate a snippet which contains the entire request Postman is firing. You can even choose the language for the snippet. I find it quite handy when I need to debug stuff.

Hope this helps.

For someone who needs quick reference of C# Escape Sequences that can be used in string literals:

\t     Horizontal tab (ASCII code value: 9)

\n     Line feed (ASCII code value: 10)

\r     Carriage return (ASCII code value: 13)

\'     Single quotation mark

\"     Double quotation mark

\\     Backslash

\?     Literal question mark

\x12     ASCII character in hexadecimal notation (e.g. for 0x12)

\x1234     Unicode character in hexadecimal notation (e.g. for 0x1234)

It's worth mentioning that these (in most cases) are universal codes. So \t is 9 and \n is 10 char value on Windows and Linux. But newline sequence is not universal. On Windows it's \n\r and on Linux it's just \n. That's why it's best to use Environment.Newline which gets adjusted to current OS settings. With .Net Core it gets really important.

I'm aware this question is a bit old. But since I stumbled on this while doing research, I thought a little addition might be helpful.

As stated the error cannot be solved by the client, since it is a network related issue. However, what you can do is retry connecting a few times. This may work as a workaround until the real issue is fixed.

for (int retries = 0; retries < 3; retries++) {
    try {
        final HttpClient client = createHttpClientWithDefaultSocketFactory(null, null);
        final HttpResponse response = client.execute(get);
        final int statusCode = response.getStatusLine().getStatusCode();
        if (statusCode != 200) {
            throw new IllegalStateException("GET Request on '" + get.getURI().toString() + "' resulted in " + statusCode);
        } else {                
            return response.getEntity();
        }
    } catch (final java.net.SocketTimeoutException e) {
        // connection timed out...let's try again                
    }
}

Maybe this helps someone.

this might help someone who had similar issue like me , i followed all naming and interface standards., But i was still facing issue.

My param name was -->  update_datetime 

I wanted to fetch my entities based on the update_datetime in the descending order, and i was getting the error

org.springframework.data.mapping.PropertyReferenceException: No property update found for type Release!

Somehow it was not reading the Underscore character --> ( _ )

so for workaround i changed the property name as  --> updateDatetime 

and then used the same for using JpaRepository methods.

It Worked !

It looks like you have everything correct according to Laravel docs, but you have a typo

$item->push($product);

Should be

$items->push($product);

I also want to think the actual method you're looking for is put

$items->put('products', $product);

give this a try,

insert into tableName (ImageColumn) 
SELECT BulkColumn 
FROM Openrowset( Bulk 'image..Path..here', Single_Blob) as img

INSERTING

REFRESHING THE TABLE

You can replace

<input type="text" id="userid" name="userid" value="Please enter the user ID" />

With:

<input type="text" id="userid" name="userid" placeholder="Please enter the user ID" />

The placeholder is used to replace value as how you wanted people to be able to Type in the text box without having to click multiple times or using ctrl + a. Placeholder makes it so it isn't a value but as the name suggests a place holder. That is what is used in multiple online forms that says "Username here" or "Email" and when you click on it the "Email" disappears and you can start typing right away.

Inline methods are simply a compiler optimization where the code of a function is rolled into the caller.

There's no mechanism by which to do this in C#, and they're to be used sparingly in languages where they are supported -- if you don't know why they should be used somewhere, they shouldn't be.

Edit: To clarify, there are two major reasons they need to be used sparingly:

1. It's easy to make massive binaries by using inline in cases where it's not necessary
2. The compiler tends to know better than you do when something should, from a performance standpoint, be inlined

It's best to leave things alone and let the compiler do its work, then profile and figure out if inline is the best solution for you. Of course, some things just make sense to be inlined (mathematical operators particularly), but letting the compiler handle it is typically the best practice.

Your image is actually upside down. But it has a meta attribute "Orientation" which tells the viewer it should be the rotated 180 degrees. Some devices/viewers don't obey this rule.

Open it in Chrome: right way up Open it in FF: right way up Open it in IE: upside down

Open it in Paint: Upside down Open it in Photoshop: Right way up. etc.

To open a terminal in VS code just type CTRL + ~ which will open the terminal. Here are the steps:

1. Check for the particular component where you need to generate the new component.

2. Redirect the path to the particular folder/component where you need to generate another component

FOR EXAMPLE: cd src/app/particularComponent

In the place of particularComponent, type the component name in which you need to generate the new component.

3. Once you are in the component where you need to generate the new component, just type this command: ng g c NewComponentName

(Change the name NewComponentName to your required component name.)

You can look at sorting the string -- treat it as a char array -- and then do a modified binary search which counts occurrences? But I agree with @tofutim that traversing it is the most efficient -- O(N) versus O(N * logN) + O(logN)

It's all about the linkage.

The previous answers provided good explainations about extern.

But I want to add an important point.

You ask about extern in C++ not in C and I don't know why there is no answer mentioning about the case when extern comes with const in C++.

In C++, a const variable has internal linkage by default (not like C).

So this scenario will lead to linking error:

Source 1 :

const int global = 255; //wrong way to make a definition of global const variable in C++

Source 2 :

extern const int global; //declaration

It need to be like this:

Source 1 :

extern const int global = 255; //a definition of global const variable in C++

Source 2 :

extern const int global; //declaration

To round up you can use modulus.

The second part of the equation will add to True if there's a remainder. (True = 1; False = 0)

ex: 3/2

answer=$(((3 / 2) + (3 % 2 > 0)))
echo $answer
2

ex: 100 / 2

answer=$(((100 / 2) + (100 % 2 > 0)))
echo $answer

You have to check which version of Excel you are targeting?

If you are targeting Excel 2010 use version 14 (as per Grant's screenshot answer), Excel 2007 use version 12 . You can not support Excel 2003 using vS2012 as they do not have the correct Interop dll installed.

var desiredCollection=collection.GetRange((collection.Count-(1+N)), N);

if(strtotime($row['database_date']) > strtotime('now')) echo $row['database_date'];
else echo date("d-m-Y");

No need to check the hours because if they are on the same day it will show the same date either way...

Just add

.flex-control-thumbs li {
width: auto; 
}

I was faced with this same problem today but since our daylight saving starts and stops at differing times from the USA (at least from my understanding), I used a slightly different route..

var arr = [];
for (var i = 0; i < 365; i++) {
 var d = new Date();
 d.setDate(i);
 newoffset = d.getTimezoneOffset();
 arr.push(newoffset);
}
DST = Math.min.apply(null, arr);
nonDST = Math.max.apply(null, arr);

Then you simply compare the current timezone offset with DST and nonDST to see which one matches.

With help of destructuring assignment it can be more readable:

let [first, ...rest] = "good_luck_buddy".split('_')
rest = rest.join('_')

In Java int is a primitive data type while Integer is a Helper class, it is use to convert for one data type to other.

For example:

         double doubleValue = 156.5d;
         Double doubleObject  = new Double(doubleValue);
         Byte myByteValue = doubleObject.byteValue ();
         String myStringValue = doubleObject.toString();

Primitive data types are store the fastest available memory where the Helper class is complex and store in heap memory.

reference from "David Gassner" Java Essential Training.

try this

String t1 = name.getText().toString();
Integer t2 = Integer.parseInt(mynum.getText().toString());

boolean ins = myDB.adddata(t1,t2);

public boolean adddata(String name, Integer price)

If you really want an 'Int only' implementation and don't want to coerce to/from Double, you'll need to implement it. Here is a trivial implementation; there are faster algorithms but this will work:

func pow (_ base:Int, _ power:UInt) -> Int {
  var answer : Int = 1
  for _ in 0..<power { answer *= base }
  return answer
}

> pow (2, 4)
$R3: Int = 16
> pow (2, 8)
$R4: Int = 256
> pow (3,3)
$R5: Int = 27

In a real implementation you'd probably want some error checking.

An interesting project which could help you out in your task is JSS.

JSS is a better abstraction over CSS. It uses JavaScript as a language to describe styles in a declarative and maintainable way. It is a high performance JS to CSS compiler which works at runtime in the browsers and server-side.

JSS library allows you to inject in the DOM/head section using the .attach() function.

Repl online version for evaluation.

Further information on JSS.

An example:

// Use plugins.
jss.use(camelCase())

// Create your style.
const style = {
  myButton: {
    color: 'green'
  }
}

// Compile styles, apply plugins.
const sheet = jss.createStyleSheet(style)

// If you want to render on the client, insert it into DOM.
sheet.attach()

Joining the party late, but just as a complement, I ran into some problems with Seaborn not so long ago, because CoLab installed a version with !pip that wasn't updated. In my specific case, I couldn't use Scatterplot, for example. The answer to this is below:

To install the module, all you need is:

!pip install seaborn

To upgrade it to the most updated version:

!pip install --upgrade seaborn

If you want to install a specific version

!pip install seaborn==0.9.0

I believe all the rules common to pip apply normally, so that pretty much should work.

I think it's not possible to select by a css value (display)

edit:

in my opinion, it would make sense to use a bit of jquery here:

$('#your_container > div:visible:last').addClass('last-visible-div');

If you are using LINUX, you can use pyALSAAUDIO. For windows, we have PyAudio and there is also a library called SoundAnalyse.

I found an example for Linux here:

#!/usr/bin/python
## This is an example of a simple sound capture script.
##
## The script opens an ALSA pcm for sound capture. Set
## various attributes of the capture, and reads in a loop,
## Then prints the volume.
##
## To test it out, run it and shout at your microphone:

import alsaaudio, time, audioop

# Open the device in nonblocking capture mode. The last argument could
# just as well have been zero for blocking mode. Then we could have
# left out the sleep call in the bottom of the loop
inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE,alsaaudio.PCM_NONBLOCK)

# Set attributes: Mono, 8000 Hz, 16 bit little endian samples
inp.setchannels(1)
inp.setrate(8000)
inp.setformat(alsaaudio.PCM_FORMAT_S16_LE)

# The period size controls the internal number of frames per period.
# The significance of this parameter is documented in the ALSA api.
# For our purposes, it is suficcient to know that reads from the device
# will return this many frames. Each frame being 2 bytes long.
# This means that the reads below will return either 320 bytes of data
# or 0 bytes of data. The latter is possible because we are in nonblocking
# mode.
inp.setperiodsize(160)

while True:
    # Read data from device
    l,data = inp.read()
    if l:
        # Return the maximum of the absolute value of all samples in a fragment.
        print audioop.max(data, 2)
    time.sleep(.001)

Could use the following and then explode the post result explode(",", $_POST['data']); to give an array of results.

var data = new Array();
$("input[name='checkBoxesName']:checked").each(function(i) {
    data.push($(this).val());
});

It seems that the only parameter that allows you to inject custom text is the "quote".

https://www.facebook.com/sharer/sharer.php?u=THE_URL&quote=THE_CUSTOM_TEXT

The additional include directories are relative to the project dir. This is normally the dir where your project file, *.vcproj, is located. I guess that in your case you have to add just "include" to your include and library directories.

If you want to be sure what your project dir is, you can check the value of the $(ProjectDir) macro. To do that go to "C/C++ -> Additional Include Directories", press the "..." button and in the pop-up dialog press "Macros>>".

I know this is an old post, but i was having a problem like the OP and this is what i came up with.

Example of array you could pass. You could re order this if a particular order was required, but for this question this will do what is asked.

$argument_set = array (8 => 'lots', 5 => 'of', 1 => 'data', 2 => 'here');

This is manageable, easy to read and the data extraction points can be added and removed at a moments notice anywhere in coding and still avoid a massive rewrite. I used integer keys to tally with the OP original question but string keys could be used just as easily. In fact for readability I would advise it.

Stick this in an external file for ease

function unknown_number_arguments($argument_set) {

    foreach ($argument_set as $key => $value) {

        # create a switch with all the cases you need. as you loop the array 
        # keys only your submitted $keys values will be found with the switch. 
        switch ($key) {
            case 1:
                # do stuff with $value
                break;
            case 2:
                # do stuff with $value;
                break;
            case 3:
                # key 3 omitted, this wont execute 
                break;
            case 5:
                # do stuff with $value;
                break;
            case 8:
                # do stuff with $value;
                break;
            default:
                # no match from the array, do error logging?
                break;
        }
    }
return;
}

put this at the start if the file.

$argument_set = array(); 

Just use these to assign the next piece of data use numbering/naming according to where the data is coming from.

$argument_set[1][] = $some_variable; 

And finally pass the array

unknown_number_arguments($argument_set);

Regarding TypeDescriptor from Sean's reply (I can't comment because I have a bad reputation)... one advantage to using TypeDescriptor over GetProperties() is that TypeDescriptor has a mechanism for dynamically attaching properties to objects at runtime and normal reflection will miss these.

For example, when working with PowerShell's PSObject, which can have properties and methods added at runtime, they implemented a custom TypeDescriptor which merges these members in with the standard member set. By using TypeDescriptor, your code doesn't need to be aware of that fact.

Components, controls, and I think maybe DataSets also make use of this API.

file_put_contents("filelist.txt", "");

You can redirect by using the header() function to modify the Location header.

You can get them like this

$('#save_value').click(function() {
    $('.ads_Checkbox:checked').each(function() {
        alert($(this).val());
    });
});

jsfiddle

Although there isn't a syntax, you can still get close by using the built-in block comment buttons:

If you're not viewing the Edit toolbar already, right-click on the toolbar and enable the Edit toolbar:

Then, select a block of code and hit the "Comment Block" button; or if it's already commented out, use the "Uncomment Block" button:

Fast and easy!

lol .... all you have to do is make sure that

addKeyListener(this);

is placed correctly in your code.

Best is to install it using rvm(ruby version manager).
Run following commands in a terminal:

sudo apt-get update
sudo apt-get install build-essential make curl
\curl -L https://get.rvm.io | bash -s stable
source ~/.bash_profile
rvm install ruby-2.1.4

Then check ruby versions installed and in use:

rvm list
rvm use --default ruby-2.1.4

Also you can directly add ruby bin path to PATH variable. Ruby is installed in

$HOME/.rvm/rubies export PATH=$PATH:$HOME/.rvm/rubies/ruby-2.1.4/bin

Didn't find any solution that would work with UTF-8 characters. String.fromCharCode is good until you meet 2 byte character.

For example Hüser will come as [0x44,0x61,0x6e,0x69,0x65,0x6c,0x61,0x20,0x48,0xc3,0xbc,0x73,0x65,0x72]

But if you go through it with String.fromCharCode you will have Hüser as each byte will be converted to a char separately.

Solution

Currently I'm using following solution:

function pad(n) { return (n.length < 2 ? '0' + n : n); }
function decodeUtf8(data) {
  return decodeURIComponent(
    data.map(byte => ('%' + pad(byte.toString(16)))).join('')
  );
}

I had the same issue on Windows 7. The cause was, that I had been connected to VPN using Cisco AnyConnect Secure Mobility Client.

Looks like you are doing this from scratch. Try using available reverse engineering tools like Netbeans Entities from Database to at least get the basics automated (like embedded ids). This can become a huge headache if you have many tables. I suggest avoid reinventing the wheel and use as many tools available as possible to reduce coding to the minimum and most important part, what you intent to do.

Although this question is already answered (tl;dr: yes, an empty href value is valid), none of the existing answers references the relevant specifications.

An empty string can’t be a URI. However, the href attribute doesn’t only take URIs as value, but also URI references. An empty string may be a URI reference.

HTML 4.01

HTML 4.01 uses RFC 2396, where it says in section 4.2. Same-document References (bold emphasis mine):

A URI reference that does not contain a URI is a reference to the current document. In other words, an empty URI reference within a document is interpreted as a reference to the start of that document, and a reference containing only a fragment identifier is a reference to the identified fragment of that document.

RFC 2396 is obsoleted by RFC 3986 (which is currently IETF’s URI standard), which essentially says the same.

HTML5

HTML5 uses (valid URL potentially surrounded by spaces ? valid URL) W3C’s URL spec, which has been discontinued. WHATWG’s URL Standard should be used instead (see the last section).

HTML 5.1

HTML 5.1 uses (valid URL potentially surrounded by spaces ? valid URL) WHATWG’s URL Standard (see the next section).

WHATWG HTML

WHATWG’s HTML uses (valid URL potentially surrounded by spaces) the definition of valid URL string from WHATWG’s URL Standard, where it says that it can be a relative-URL-with-fragment string, which must at least be a relative-URL string, which can be a path-relative-scheme-less-URL string, which is a path-relative-URL string that doesn’t start with a scheme string followed by :, and its definition says (bold emphasis mine):

A path-relative-URL string must be zero or more URL-path-segment strings, separated from each other by U+002F (/), and not start with U+002F (/).

Do you have the required permission set in your Manifest?

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

best thing to use:

      long currenTime = System.currentTimeMillis();
      long oneHourLater = currentTime + TimeUnit.HOURS.toMillis(1l);

Similarly, you can add MONTHS, DAYS, MINUTES etc

If this isn't a good solution for any reason, please let me know. It worked fine for me.

What I did is to hide the Sidebar and then make appear the navbar with breakpoints

@media screen and (max-width: 771px) {
    #fixed-sidebar {
        display: none;
    }
    #navbar-superior {
        display: block !important;
    }
}

Since this is a rather popular question, I'm inclined to share a nice solution using BFC.
Codepen sample of the following here.

.left {
  float: left;
  width: 100px;
}
.right {
  overflow: auto;
}

In this case, overflow: auto triggers context behavior and makes the right element expand only to the available remaining width and it will naturally expand to full width if .left disappears. A highly useful and clean trick for many UI layouts, but perhaps hard to understand the "why it works" at first.

var obj = new Dictionary<string, object>;
...
Console.WriteLine(obj["MyString"]);

I think that only works because everything has a ToString(), otherwise you'd have to know the type that it was and cast the 'object' to that type.

Some of these are useful more often than others, I'm trying to be thorough.

1. It may be far more natural to access a collection, in this case what is effectively a "dictionary", using the more direct dot notation.

2. It seems as if this could be used as a really nice Tuple. You can still call your members "Item1", "Item2" etc... but now you don't have to, it's also mutable, unlike a Tuple. This does have the huge drawback of lack of intellisense support.

3. You may be uncomfortable with "member names as strings", as is the feel with the dictionary, you may feel it is too like "executing strings", and it may lead to naming conventions getting coded in, and dealing with working with morphemes and syllables when code is trying understand how to use members :-P

4. Can you assign a value to an ExpandoObject itself or just it's members? Compare and contrast with dynamic/dynamic[], use whichever best suits your needs.

5. I don't think dynamic/dynamic[] works in a foreach loop, you have to use var, but possibly you can use ExpandoObject.

6. You cannot use dynamic as a data member in a class, perhaps because it's at least sort of like a keyword, hopefully you can with ExpandoObject.

7. I expect it "is" an ExpandoObject, might be useful to label very generic things apart, with code that differentiates based on types where there is lots of dynamic stuff being used.

Be nice if you could drill down multiple levels at once.

var e = new ExpandoObject();
e.position.x = 5;
etc...

Thats not the best possible example, imagine elegant uses as appropriate in your own projects.

It's a shame you cannot have code build some of these and push the results to intellisense. I'm not sure how this would work though.

Be nice if they could have a value as well as members.

var fifteen = new ExpandoObject();
fifteen = 15;
fifteen.tens = 1;
fifteen.units = 5;
fifteen.ToString() = "fifteen";
etc...

For others that stumble on this, you can also use ejs params/props in conditional statements:

recipes.js File:

app.get("/recipes", function(req, res) {
    res.render("recipes.ejs", {
        recipes: recipes
    });
});

recipes.ejs File:

<%if (recipes.length > 0) { %>
// Do something with more than 1 recipe
<% } %>

You can add line-height:51px to #AlertDiv h1 if you know it's only ever going to be one line. Also add text-align:center to #AlertDiv.

#AlertDiv {
    top:198px;
    left:365px;
    width:62px;
    height:51px;
    color:white;
    position:absolute;
    text-align:center;
    background-color:black;
}

#AlertDiv h1 {
    margin:auto;
    line-height:51px;
    vertical-align:middle;
}

The demo below also uses negative margins to keep the #AlertDiv centered on both axis, even when the window is resized.

If what you're looking for is simply to blur the image edges you can simply use the box-shadow with an inset.

Working example: http://jsfiddle.net/d9Q5H/1/

HTML:

<div class="image-blurred-edge"></div>

CSS

.image-blurred-edge {
    background-image: url('http://lorempixel.com/200/200/city/9');
    width: 200px;
    height: 200px;
    /* you need to match the shadow color to your background or image border for the desired effect*/
    box-shadow: 0 0 8px 8px white inset;
}

You can redirect stdout to /dev/null.

yum install nano > /dev/null

Or you can redirect both stdout and stderr,

yum install nano &> /dev/null.

But if the program has a quiet option, that's even better.

You don't have to, but some people like to explicitly initialize all variables (I do too). Especially those who program in a variety of languages, it's just easier to have the rule of always initializing your variables rather than deciding case-by-case/language-by-language.

For instance Java has default values for Boolean, int etc .. C on the other hand doesn't automatically give initial values, whatever happens to be in memory is what you end up with unless you assign a value explicitly yourself.

In your case above, as you discovered, the code works just as well without the initialization, esp since the variable is set in the next line which makes it appear particularly redundant. Sometimes you can combine both of those lines (declaration and initialization - as shown in some of the other posts) and get the best of both approaches, i.e., initialize the your variable with the result of the email1.equals (email2); operation.

When working with Angular the recent update to Angular 8 introduced that a static property inside @ViewChild() is required as stated here and here. Then your code would require this small change:

@ViewChild('one') d1:ElementRef;

into

// query results available in ngOnInit
@ViewChild('one', {static: true}) foo: ElementRef;

OR

// query results available in ngAfterViewInit
@ViewChild('one', {static: false}) foo: ElementRef;

for (var key in data) {
    alert("User " + data[key] + " is #" + key); // "User john is #234"
}

try some thing like blow:

SString otherParametersUrServiceNeed =  "Company=acompany&Lng=test&MainPeriod=test&UserID=123&CourseDate=8:10:10";
String request = "http://android.schoolportal.gr/Service.svc/SaveValues";

URL url = new URL(request); 
HttpURLConnection connection = (HttpURLConnection) url.openConnection();   
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false); 
connection.setRequestMethod("POST"); 
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" + Integer.toString(otherParametersUrServiceNeed.getBytes().length));
connection.setUseCaches (false);

DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
wr.writeBytes(otherParametersUrServiceNeed);

   JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");

wr.writeBytes(jsonParam.toString());

wr.flush();
wr.close();

Well to obtain all different values in a Dataframe you can use distinct. As you can see in the documentation that method returns another DataFrame. After that you can create a UDF in order to transform each record.

For example:

val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")

// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct

// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)

// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))

It's really simple, just download the latest toolkit from Codeplex and add the extracted AjaxControlToolkit.dll to your toolbox in Visual Studio by right clicking the toolbox and selecting 'choose items'. You will then have the controls in your Visual STudio toolbox and using them is just a matter of dragging and dropping them onto your form, of course don't forget to add a asp:ScriptManager to every page that uses controls from the toolkit, or optionally include it in your master page only and your content pages will inherit the script manager.

Get started quickly

You simply type vim into the terminal to open it and start a new file.

You can pass a filename as an option and it will open that file, e.g. vim main.c. You can open multiple files by passing multiple file arguments.

Vim has different modes, unlike most editors you have probably used. You begin in NORMAL mode, which is where you will spend most of your time once you become familiar with vim.

To return to NORMAL mode after changing to a different mode, press Esc. It's a good idea to map your Caps Lock key to Esc, as it's closer and nobody really uses the Caps Lock key.

The first mode to try is INSERT mode, which is entered with a for append after cursor, or i for insert before cursor.

To enter VISUAL mode, where you can select text, use v. There are many other variants of this mode, which you will discover as you learn more about vim.

To save your file, ensure you're in NORMAL mode and then enter the command :w. When you press :, you will see your command appear in the bottom status bar. To save and exit, use :x. To quit without saving, use :q. If you had made a change you wanted to discard, use :q!.

Configure vim to your liking

You can edit your ~/.vimrc file to configure vim to your liking. It's best to look at a few first (here's mine) and then decide which options suits your style.

This is how mine looks:

To get the file explorer on the left, use NERDTree. For the status bar, use vim-airline. Finally, the color scheme is solarized.

Further learning

You can use man vim for some help inside the terminal. Alternatively, run vimtutor which is a good hands-on starting point.

It's a good idea to print out a Vim Cheatsheet and keep it in front of you while you're learning vim.

Good luck!

If you are truly dynamically setting this, you should set the .Url field of instance of the proxy class you are calling.

Setting the value in the .config file from within your program:

1. Is a mess;

2. Might not be read until the next application start.

If it is only something that needs to be done once per installation, I'd agree with the other posters and use the .config file and the dynamic setting.

You can also try to write different elements in different cookies. Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the user's system. Consider explode() to set one cookie with multiple names and values. It is not recommended to use serialize() for this purpose, because it can result in security holes. Look at setcookie PHP function for more details

Adding this to my connection string worked for me:

Trusted_Connection=true

1. Try to flush privileges again.

2. Try to restart server to reload grants.

3. Try create a user with host "192.168.233.163". "%" appears to not allow all (it's weird)

How about without recreating a new list, you can do by indexing:

>>> foo = ['1a','2b','3c','4d']
>>> for i in range(len(foo)):
...     print foo[-(i+1)]
...
4d
3c
2b
1a
>>>

OR

>>> length = len(foo)
>>> for i in range(length):
...     print foo[length-i-1]
...
4d
3c
2b
1a
>>>

Bonus: why do people seemingly always use big-oh when talking informally?

Because in big-oh, this loop:

for i = 1 to n do
    something in O(1) that doesn't change n and i and isn't a jump

is O(n), O(n^2), O(n^3), O(n^1423424). big-oh is just an upper bound, which makes it easier to calculate because you don't have to find a tight bound.

The above loop is only big-theta(n) however.

What's the complexity of the sieve of eratosthenes? If you said O(n log n) you wouldn't be wrong, but it wouldn't be the best answer either. If you said big-theta(n log n), you would be wrong.

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine

Be aware of that only 32 bit version of PHP is available on the Windows platform.

Then if you for instance shift << or >> more than by 31 bits, results are unexpectable. Usually the original number instead of zeros will be returned, and it can be a really tricky bug.

Of course if you use 64 bit version of PHP (Unix), you should avoid shifting by more than 63 bits. However, for instance, MySQL uses the 64-bit BIGINT, so there should not be any compatibility problems.

UPDATE: From PHP 7 Windows, PHP builds are finally able to use full 64 bit integers: The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). 64-bit platforms usually have a maximum value of about 9E18, except on Windows prior to PHP 7, where it was always 32 bit.

Here's one very simple example:

var counter = 0;

function getSlug(tokens) {
    var slug = '';

    if (!!tokens.length) {
        slug = tokens.shift();
        slug = slug.toLowerCase();
        slug += getSlug(tokens);

        counter += 1;
        console.log('THE SLUG ELEMENT IS: %s, counter is: %s', slug, counter);
    }

    return slug;
}

var mySlug = getSlug(['This', 'Is', 'My', 'Slug']);
console.log('THE SLUG IS: %s', mySlug);

Notice that the counter counts "backwards" in regards to what slug's value is. This is because of the position at which we are logging these values, as the function recurs before logging -- so, we essentially keep nesting deeper and deeper into the call-stack before logging takes place.

Once the recursion meets the final call-stack item, it trampolines "out" of the function calls, whereas, the first increment of counter occurs inside of the last nested call.

I know this is not a "fix" on the Questioner's code, but given the title I thought I'd generically exemplify Recursion for a better understanding of recursion, outright.

Stack Overflow has solved a similar problem with long lines of code by using a DIV and having overflow-x:auto. CSS can't break up words for you.

The issue is that you're not saving the mysqli connection. Change your connect to:

$aVar = mysqli_connect('localhost','tdoylex1_dork','dorkk','tdoylex1_dork');

And then include it in your query:

$query1 = mysqli_query($aVar, "SELECT name1 FROM users
    ORDER BY RAND()
    LIMIT 1");
$aName1 = mysqli_fetch_assoc($query1);
$name1 = $aName1['name1'];

Also don't forget to enclose your connections variables as strings as I have above. This is what's causing the error but you're using the function wrong, mysqli_query returns a query object but to get the data out of this you need to use something like mysqli_fetch_assoc http://php.net/manual/en/mysqli-result.fetch-assoc.php to actually get the data out into a variable as I have above.

For JavaScript arrays, you use push().

var a = [];
a.push(12);
a.push(32);

For jQuery objects, there's add().

$('div.test').add('p.blue');

Note that while push() modifies the original array in-place, add() returns a new jQuery object, it does not modify the original one.

Make sure you installed the nuget package Microsoft.AspNet.Identity.Owin. Then add System.Net.Http namespace.

Public SUB test()
    Dim mdate As Date
    mdate = now()
    MsgBox (Round(CDbl(mdate), 0))
End SUB

x^y is not "x to the power of y". It's "x XOR y".

I have just sent an email with gmail through Python. Try to use smtplib.SMTP_SSL to make the connection. Also, you may try to change the gmail domain and port.

So, you may get a chance with:

server = smtplib.SMTP_SSL('smtp.googlemail.com', 465)
server.login(gmail_user, password)
server.sendmail(gmail_user, TO, BODY)

As a plus, you could check the email builtin module. In this way, you can improve the readability of you your code and handle emails headers easily.

Can't you do this with just one heap? Update: no. See the comment.

Invariant: After reading 2*n inputs, the min-heap holds the n largest of them.

Loop: Read 2 inputs. Add them both to the heap, and remove the heap's min. This reestablishes the invariant.

So when 2n inputs have been read, the heap's min is the nth largest. There'll need to be a little extra complication to average the two elements around the median position and to handle queries after an odd number of inputs.

In my particular project I couldn't get it to work, and used declare var $;. Not a clean/recommended solution, it doesnt recognise the JQuery variables, but I had no errors after using that (and had to for my automatic builds to succeed).

Had issues using the code in the answer provided by @haynar above (wouldn't play on Chrome), and it seems that one of the more modern ways to ensure it plays is to use the video tag

Example:

<video controls="controls" width="800" height="600" 
       name="Video Name" src="http://www.myserver.com/myvideo.mov"></video>

This worked like a champ for my .mov file (generated from Keynote) in both Safari and Chrome, and is listed as supported in most modern browsers (The video tag is supported in Internet Explorer 9+, Firefox, Opera, Chrome, and Safari.)

Note: Will work in IE / etc.. if you use MP4 (Mov is not officially supported by those guys)

Native JS Examples

Get NodeList of elements

var elem = document.querySelectorAll('[data-id="container"]')

html: <div data-id="container"></div>

Get the first element

var firstElem = document.querySelector('[id="container"]')

html: <div id="container"></div>

Target a collection of nodes which returns a nodelist

document.getElementById('footer').querySelectorAll('[data-id]')

html:

<div class="footer">
    <div data-id="12"></div>
    <div data-id="22"></div>
</div>

Get elements based on multiple (OR) data values

document.querySelectorAll('[data-section="12"],[data-selection="20"]')

html:

<div data-selection="20"></div>
<div data-section="12"></div>

Get elements based on combined (AND) data values

document.querySelectorAll('[data-prop1="12"][data-prop2="20"]')

html:

<div data-prop1="12" data-prop2="20"></div>

Get items where the value starts with

document.querySelectorAll('[href^="https://"]')

In C++ the "^" operator is a bitwise OR. It does not work for raising to a power. The x << n is a left shift of the binary number which is the same as multiplying x by 2 n number of times and that can only be used when raising 2 to a power. The POW function is a math function that will work generically.

In your php file just enter this code:

error_reporting(0);

This will report no errors to the user. If you somehow want, then just comment this.

what worked for me was and is superfast is

import pandas as pd
import dask.dataframe as dd
import time
t=time.clock()
df_train = dd.read_csv('../data/train.csv', usecols=[col1, col2])
df_train=df_train.compute()
print("load train: " , time.clock()-t)

Another working solution is:

import pandas as pd 
from tqdm import tqdm

PATH = '../data/train.csv'
chunksize = 500000 
traintypes = {
'col1':'category',
'col2':'str'}

cols = list(traintypes.keys())

df_list = [] # list to hold the batch dataframe

for df_chunk in tqdm(pd.read_csv(PATH, usecols=cols, dtype=traintypes, chunksize=chunksize)):
    # Can process each chunk of dataframe here
    # clean_data(), feature_engineer(),fit()

    # Alternatively, append the chunk to list and merge all
    df_list.append(df_chunk) 

# Merge all dataframes into one dataframe
X = pd.concat(df_list)

# Delete the dataframe list to release memory
del df_list
del df_chunk
