As John Saunders says, check if the class/property names matches the capital casing of your XML. If this isn't the case, the problem will also occur.

Use:

1..10 | % { write "loop $_" }

Output:

PS D:\temp> 1..10 | % { write "loop $_" }
loop 1
loop 2
loop 3
loop 4
loop 5
loop 6
loop 7
loop 8
loop 9
loop 10

Just use the command S <- S[,-2] to remove the second column. Similarly to delete a row, for example, to delete the second row use S <- S[-2,].

Extracting the title is not difficult, and you have many options, search here on Stack Overflow for "Java HTML parsers". One of them is Jsoup.

You can navigate the page using DOM if you know the page structure, see http://jsoup.org/cookbook/extracting-data/dom-navigation

It's a good library and I've used it in my last projects.

• Debug: fine-grained statements concerning program state, typically used for debugging;

• Info: informational statements concerning program state, representing program events or behavior tracking;

• Warn: statements that describe potentially harmful events or states in the program;

• Error: statements that describe non-fatal errors in the application; this level is used quite often for logging handled exceptions;

• Fatal: statements representing the most severe of error conditions, assumedly resulting in program termination.

Found on http://www.beefycode.com/post/Log4Net-Tutorial-pt-1-Getting-Started.aspx

Simple just run the following command to get the output to your terminal:

adb shell logcat

I think I made a faster byte array to string convertor:

public static class HexTable
{
    private static readonly string[] table = BitConverter.ToString(Enumerable.Range(0, 256).Select(x => (byte)x).ToArray()).Split('-');

    public static string ToHexTable(byte[] value)
    {
        StringBuilder sb = new StringBuilder(2 * value.Length);

        for (int i = 0; i < value.Length; i++)
            sb.Append(table[value[i]]);

        return sb.ToString();
    }

And the test set up:

static void Main(string[] args)
{
        const int TEST_COUNT = 10000;
        const int BUFFER_LENGTH = 100000;

        Random random = new Random();

        Stopwatch sw = new Stopwatch();
        Stopwatch sw2 = new Stopwatch();

        byte[] buffer = new byte[BUFFER_LENGTH];
        random.NextBytes(buffer);

        sw.Start();
        for (int j = 0; j < TEST_COUNT; j++)
            HexTable.ToHexTable(buffer);

        sw.Stop();

        sw2.Start();
        for (int j = 0; j < TEST_COUNT; j++)
            ToHexChar.ToHex(buffer);

        sw2.Stop();

        Console.WriteLine("Hex Table Elapsed Milliseconds: {0}", sw.ElapsedMilliseconds);
        Console.WriteLine("ToHex Elapsed Milliseconds: {0}", sw2.ElapsedMilliseconds);
    }

The ToHexChar.ToHEx() method is the ToHex() method shown previously.

Results are as follows:

HexTable = 11808 ms ToHEx = 12168ms

It may not look that much of a difference, but it's still faster :)

Just put DROP TABLE IF EXISTS `tablename`; before your CREATE TABLE statement.

That statement drops the table if it exists but will not throw an error if it does not.

checkexists() {
    while [ -n "$1" ]; do
        [ -n "$(which "$1")" ] || echo "$1": command not found
        shift
    done
}

IE9+ (Vista+) solution, without creating new text nodes:

var div = document.getElementById("divID");
div.textContent += data + " ";

However, this didn't quite do the trick for me since I needed a new line after each message, so my DIV turned into a styled UL with this code:

var li = document.createElement("li");
var text = document.createTextNode(data);
li.appendChild(text);
ul.appendChild(li);

From https://developer.mozilla.org/en-US/docs/Web/API/Node/textContent :

Differences from innerHTML

innerHTML returns the HTML as its name indicates. Quite often, in order to retrieve or write text within an element, people use innerHTML. textContent should be used instead. Because the text is not parsed as HTML, it's likely to have better performance. Moreover, this avoids an XSS attack vector.

date() itself is only for formatting, but it accepts a second parameter.

date("F j, Y", time() - 60 * 60 * 24);

To keep it simple I just subtract 24 hours from the unix timestamp.

A modern oop-approach is using DateTime

$date = new DateTime();
$date->sub(new DateInterval('P1D'));
echo $date->format('F j, Y') . "\n";

Or in your case (more readable/obvious)

$date = new DateTime();
$date->add(DateInterval::createFromDateString('yesterday'));
echo $date->format('F j, Y') . "\n";

(Because DateInterval is negative here, we must add() it here)

See also: DateTime::sub() and DateInterval

try changing the host, this is the new one, I got this configuring mozilla thunderbird

Host = "smtp.googlemail.com"

that work for me

I did this, also with jQuery:

$('input[type=search]').on('focus', function(){
  // replace CSS font-size with 16px to disable auto zoom on iOS
  $(this).data('fontSize', $(this).css('font-size')).css('font-size', '16px');
}).on('blur', function(){
  // put back the CSS font-size
  $(this).css('font-size', $(this).data('fontSize'));
});

Of course, some other elements in the interface may have to be adapted if this 16px font-size breaks the design.

The answer of ADTC works fine, but I've find another solution, so I post it here if someone wants something different.

I think ADTC's solution is better, but mine's also works.

Here is the other solution I found

select p.name
from   person p
where  instr(p.name,chr(8211)) > 0; --contains the character chr(8211) 
                                    --at least 1 time

Thank you.

If you're looking for a Kafka error, this might because the upgrade of Kafka's version from 1.x to 2.x.

javax.net.ssl.SSLHandshakeException: General SSLEngine problem ... javax.net.ssl.SSLHandshakeException: General SSLEngine problem ... java.security.cert.CertificateException: No name matching *** found

or

[Producer clientId=producer-1] Connection to node -2 failed authentication due to: SSL handshake failed

The default value for ssl.endpoint.identification.algorithm was changed to https, which performs hostname verification (man-in-the-middle attacks are possible otherwise). Set ssl.endpoint.identification.algorithm to an empty string to restore the previous behaviour. Apache Kafka Notable changes in 2.0.0

When it says users are connected, what does the query "select * from pg_stat_activity;" say? Are the other users besides yourself now connected? If so, you might have to edit your pg_hba.conf file to reject connections from other users, or shut down whatever app is accessing the pg database to be able to drop it. I have this problem on occasion in production. Set pg_hba.conf to have a two lines like this:

local   all         all                               ident
host    all         all         127.0.0.1/32          reject

and tell pgsql to reload or restart (i.e. either sudo /etc/init.d/postgresql reload or pg_ctl reload) and now the only way to connect to your machine is via local sockets. I'm assuming you're on linux. If not this may need to be tweaked to something other than local / ident on that first line, to something like host ... yourusername.

Now you should be able to do:

psql postgres
drop database mydatabase;

X-XSS-Protection is a HTTP header understood by Internet Explorer 8 (and newer versions). This header lets domains toggle on and off the "XSS Filter" of IE8, which prevents some categories of XSS attacks. IE8 has the filter activated by default, but servers can switch if off by setting

   X-XSS-Protection: 0

If you do not use any placeholders (as the "exactly" seems to imply), how about string comparison instead?

If you do use placeholders, ^ and $ match the beginning and the end of a string, respectively.

In app.component.html:

 <select type="number" [(ngModel)]="selectedLevel">
          <option *ngFor="let level of levels" [ngValue]="level">{{level.name}}</option>
        </select>

And app.component.ts:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  levelNum:number;
  levels:Array<Object> = [
      {num: 0, name: "AA"},
      {num: 1, name: "BB"}
  ];

  toNumber(){
    this.levelNum = +this.levelNum;
    console.log(this.levelNum);
  }

  selectedLevel = this.levels[0];

  selectedLevelCustomCompare = {num: 1, name: "BB"}

  compareFn(a, b) {
    console.log(a, b, a && b && a.num == b.num);
    return a && b && a.num == b.num;
  }
}

Noting down my situation here may be useful to somebody,

I have to send a custom intent with multiple intent extras to a broadcast receiver in Android P,

The details are,

Receiver name: com.hardian.testservice.TestBroadcastReceiver

Intent action = "com.hardian.testservice.ADD_DATA"

intent extras are,

1. "text"="test msg",
2. "source"= 1,

Run the following in command line.

adb shell "am broadcast -a com.hardian.testservice.ADD_DATA --es text 'test msg' --es source 1 -n com.hardian.testservice/.TestBroadcastReceiver"

Hope this helps.

A 2016/2017 update will show you the bad value and column.

A new trace flag will swap the old error for a new 2628 error and will print out the column and offending value. Traceflag 460 is available in the latest cumulative update for 2016 and 2017:

https://support.microsoft.com/en-sg/help/4468101/optional-replacement-for-string-or-binary-data-would-be-truncated

Just make sure that after you've installed the CU that you enable the trace flag, either globally/permanently on the server:

...or with DBCC TRACEON:

https://docs.microsoft.com/en-us/sql/t-sql/database-console-commands/dbcc-traceon-trace-flags-transact-sql?view=sql-server-ver15

Almost everything is mentioned here. I would like to share one question which I was asked by a senior manager on database. I found the question pretty interesting and if you think about it deeply, it sort of has lot of meaning in it.

Question was - How would you describe database to your 5 year old kid ?

This should help. How can I upload files asynchronously?

As the post suggest I recommend a plugin located here http://malsup.com/jquery/form/#code-samples

edit (sorry I thought you wanted VBA).

Anytime you try to read a non-existent value from the registry, you get back a Null. Thus all you have to do is check for a Null value.

Use IsNull not IsEmpty.

Const HKEY_LOCAL_MACHINE = &H80000002

strComputer = "."
Set objRegistry = GetObject("winmgmts:\\" & _ 
    strComputer & "\root\default:StdRegProv")

strKeyPath = "SOFTWARE\Microsoft\Windows NT\CurrentVersion"
strValueName = "Test Value"
objRegistry.GetStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,strValue

If IsNull(strValue) Then
    Wscript.Echo "The registry key does not exist."
Else
    Wscript.Echo "The registry key exists."
End If

The simpler solution will be to user pyftpd library. This library allows you to spin Python FTP server in one line. It doesn’t come installed by default though, but we can install it using simple apt command

apt-get install python-pyftpdlib

now from the directory you want to serve just run the pythod module

python -m pyftpdlib -p 21 

Just a word of caution. If you are trying to open an existing JKS keystore in Java 9 onwards, you need to make sure you mention the following properties too with value as "JKS":

javax.net.ssl.keyStoreType
javax.net.ssl.trustStoreType

The reason being that the default keystore type as prescribed in java.security file has been changed to pkcs12 from jks from Java 9 onwards.

It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.

The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:

You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:

Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:

#toolbar=0&navpanes=0

So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.

string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

You can read more about the parameters that are available for customizing the way PDF files open here on Adobe's developer website.

If the value contains non-numeric characters, you can convert the value to an integer as follows:

SELECT CASE WHEN <column>~E'^\\d+$' THEN CAST (<column> AS INTEGER) ELSE 0 END FROM table;

The CASE operator checks the < column>, if it matches the integer pattern, it converts the rate into an integer, otherwise it returns 0

You have to open database connection, not workbench file with schema. It looks a bit wierd, but it makes sense when you realize what you are editing.

So, go to home tab, double click database connection (create it if you don't have it yet) and have fun.

C++20 std::rotl and std::rotr

It has arrived! http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p0553r4.html and should add it to the <bit> header.

cppreference says that the usage will be like:

#include <bit>
#include <bitset>
#include <cstdint>
#include <iostream>

int main()
{
    std::uint8_t i = 0b00011101;
    std::cout << "i          = " << std::bitset<8>(i) << '\n';
    std::cout << "rotl(i,0)  = " << std::bitset<8>(std::rotl(i,0)) << '\n';
    std::cout << "rotl(i,1)  = " << std::bitset<8>(std::rotl(i,1)) << '\n';
    std::cout << "rotl(i,4)  = " << std::bitset<8>(std::rotl(i,4)) << '\n';
    std::cout << "rotl(i,9)  = " << std::bitset<8>(std::rotl(i,9)) << '\n';
    std::cout << "rotl(i,-1) = " << std::bitset<8>(std::rotl(i,-1)) << '\n';
}

giving output:

i          = 00011101
rotl(i,0)  = 00011101
rotl(i,1)  = 00111010
rotl(i,4)  = 11010001
rotl(i,9)  = 00111010
rotl(i,-1) = 10001110

I'll give it a try when support arrives to GCC, GCC 9.1.0 with g++-9 -std=c++2a still doesn't support it.

The proposal says:

Header:

namespace std {
  // 25.5.5, rotating   
  template<class T>
    [[nodiscard]] constexpr T rotl(T x, int s) noexcept;
  template<class T>
    [[nodiscard]] constexpr T rotr(T x, int s) noexcept;

and:

25.5.5 Rotating [bitops.rot]

In the following descriptions, let N denote std::numeric_limits<T>::digits.

template<class T>
  [[nodiscard]] constexpr T rotl(T x, int s) noexcept;

Constraints: T is an unsigned integer type (3.9.1 [basic.fundamental]).

Let r be s % N.

Returns: If r is 0, x; if r is positive, (x << r) | (x >> (N - r)); if r is negative, rotr(x, -r).

template<class T>
  [[nodiscard]] constexpr T rotr(T x, int s) noexcept;

Constraints: T is an unsigned integer type (3.9.1 [basic.fundamental]). Let r be s % N.

Returns: If r is 0, x; if r is positive, (x >> r) | (x << (N - r)); if r is negative, rotl(x, -r).

A std::popcount was also added to count the number of 1 bits: How to count the number of set bits in a 32-bit integer?

b1 = (Button) findViewById(R.id.click_me);
        b1.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

                Intent i = new Intent(MainActivity.this, SecondActivity.class);
                startActivity(i);

            }
        });

You have to add the android:screenOrientation="portrait" directive in your AndroidManifest.xml. This is to be done in your <activity> tag.

In addition, the Android Developers guide states that :

[...] you should also explicitly declare that your application requires either portrait or landscape orientation with the element. For example, <uses-feature android:name="android.hardware.screen.portrait" />.

>>> import random
>>> random.randrange(5,60,5)

should work in any Python >= 2.

From a controller or view - use the following to display the version:

<?php
   echo CI_VERSION;
?>

There are no classes in C, so it's impossible to to write dynamic_cast in that language. C structures don't have methods (as a result, they don't have virtual methods), so there is nothing "dynamic" in it.

Instead of running MongoDB with:

sudo mongod

You can use mongod instead if you:

1. Locate the data folder of mongodb (usually ~/data)
2. Add permission to read + write with sudo chmod -R ugo+rw data

If you need to use sudo when running mongodb (sudo mongod), that means you don't have read and write permission on the mongodb data folder

[...new Set([
    { "name": "Joe", "age": 17 },
    { "name": "Bob", "age": 17 },
    { "name": "Carl", "age": 35 }
  ].map(({ age }) => age))]

I'm adding this by request, not because I think it directly solves the question. My solution involves a table component for displaying tables from my SQL database:

export class TableComponent<T> {

    public Data: T[] = [];

    public constructor(
        protected type: new (value: Partial<T>) => T
    ) { }

    protected insertRow(value: Partial<T>): void {
        let row: T = new this.type(value);
        this.Data.push(row);
    }
}

To put this to use, assume I have a view (or table) in my database VW_MyData and I want to hit the constructor of my VW_MyData class for every entry returned from a query:

export class MyDataComponent extends TableComponent<VW_MyData> {

    public constructor(protected service: DataService) {
        super(VW_MyData);
        this.query();
    }

    protected query(): void {
        this.service.post(...).subscribe((json: VW_MyData[]) => {
            for (let item of json) {
                this.insertRow(item);
            }
        }
    }
}

The reason this is desirable over simply assigning the returned value to Data, is say I have some code that applies a transformation to some column of VW_MyData in its constructor:

export class VW_MyData {
    
    public RawColumn: string;
    public TransformedColumn: string;


    public constructor(init?: Partial<VW_MyData>) {
        Object.assign(this, init);
        this.TransformedColumn = this.transform(this.RawColumn);
    }

    protected transform(input: string): string {
        return `Transformation of ${input}!`;
    }
}

This allows me to perform transformations, validations, and whatever else on all my data coming in to TypeScript. Hopefully it provides some insight for someone.

In Visual Studio 2017, I went to Project Properties -> Configuration Properties -> General, Selected All Platforms (1), then chose the dropdown (2) under Windows SDK Version and updated from 10.0.14393.0 to one that was installed (3). For me, that was 10.0.15063.0.

Additional details: This corrected the error in my case because Windows SDK Version helps VS select the correct paths. VC++ Directories -> Library Directories -> Edit -> Macros -> shows that macro $(WindowsSDK_LibraryPath_x86) has a path with the version number selected above.

Just remove the inner quotes - they confuse Firefox. You can just use "video/ogg; codecs=theora,vorbis".

Also, that markup works in my Minefiled 3.7a5pre, so if your ogv file doesn't play, it may be a bogus file. How did you create it? You might want to register a bug with Firefox.

Here is a shorter, cleaner way to get the IP address:

function get_ip_address(){
    foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
        if (array_key_exists($key, $_SERVER) === true){
            foreach (explode(',', $_SERVER[$key]) as $ip){
                $ip = trim($ip); // just to be safe

                if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
                    return $ip;
                }
            }
        }
    }
}

Your code seems to be pretty complete already, I cannot see any possible bugs in it (aside from the usual IP caveats), I would change the validate_ip() function to rely on the filter extension though:

public function validate_ip($ip)
{
    if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) === false)
    {
        return false;
    }

    self::$ip = sprintf('%u', ip2long($ip)); // you seem to want this

    return true;
}

Also your HTTP_X_FORWARDED_FOR snippet can be simplified from this:

// check for IPs passing through proxies
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
    // check if multiple ips exist in var
    if (strpos($_SERVER['HTTP_X_FORWARDED_FOR'], ',') !== false)
    {
        $iplist = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
        
        foreach ($iplist as $ip)
        {
            if ($this->validate_ip($ip))
                return $ip;
        }
    }
    
    else
    {
        if ($this->validate_ip($_SERVER['HTTP_X_FORWARDED_FOR']))
            return $_SERVER['HTTP_X_FORWARDED_FOR'];
    }
}

To this:

// check for IPs passing through proxies
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
    $iplist = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
        
    foreach ($iplist as $ip)
    {
        if ($this->validate_ip($ip))
            return $ip;
    }
}

You may also want to validate IPv6 addresses.

we can use append and pop to do it

def rev(s):
    i = list(s)
    o = list()
    while len(i) > 0:
        o.append(t.pop())

    return ''.join(o)

lonesomeday's answer is absolutely correct, I just thought I would add this tidbit. I had made a method a while back for getting browser in Vanilla JS and eventually curved it to replace jQuery.browser in later versions of jQuery. It does not interfere with any part of the new jQuery lib, but provides the same functionality of the traditional jQuery.browser object, as well as some other little features.

New Extended Version!

Is much more thorough for newer browser. Also, 90+% accuracy on mobile testing! I won't say 100%, as I haven't tested on every mobile browser, but new feature adds $.browser.mobile boolean/string. It's false if not mobile, else it will be a String name for the mobile device or browser (Best Guesss like: Android, RIM Tablet, iPod, etc...).

One possible caveat, may not work with some older (unsupported) browsers as it is completely reliant on userAgent string.

Python dictionaries are unordered. If you want an ordered dictionary, use collections.OrderedDict

In your case, sort the dict by key before plotting,

import matplotlib.pylab as plt

lists = sorted(d.items()) # sorted by key, return a list of tuples

x, y = zip(*lists) # unpack a list of pairs into two tuples

plt.plot(x, y)
plt.show()

Here is the result.

You could do it like this:

.switch {
  position: relative;
  display: inline-block;
  width: 90px;
  height: 34px;
}

.switch input {display:none;}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ca2222;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked + .slider {
  background-color: #2ab934;
}

input:focus + .slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked + .slider:before {
  -webkit-transform: translateX(55px);
  -ms-transform: translateX(55px);
  transform: translateX(55px);
}

/*------ ADDED CSS ---------*/

}

.on, .off
{
  color: white;
  position: absolute;
  transform: translate(-50%,-50%);
  top: 50%;
  left: 50%;
  font-size: 10px;
  font-family: Verdana, sans-serif;
}

input:checked+ .slider .on
{display: block;}

input:checked + .slider .off
{display: none;}

/*--------- END --------*/

/* Rounded sliders */
.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;}

<label class="switch">

 <div class="slider round">
  <!--ADDED HTML -->
  <span class="on">ON</span>
  <span class="off">OFF</span>
  <!--END-->
 </div>
</label>

Or pure CSS:

.switch {
  position: relative;
  display: inline-block;
  width: 90px;
  height: 34px;
}

.switch input {display:none;}

Also, there is the issue of possible 2.0 rollback. Trust me it has happened to me a couple of times so I am sure it has happened to others.

I also agree that abstraction is the best. Along with the fact, the original purpose of an ORM is to make RDBMS match up nicely to the OO concepts. However, if everything worked fine before LINQ by having to deviate a bit from OO concepts then screw 'em. Concepts and reality don't always fit well together. There is no room for militant zealots in IT.

There is probably a way (or three) to do this... however, I see one issue with your goal: how do you know when all the files have been uploaded? To rephrase in a way that makes more sense... how do you know what "all" means? According to the documentation, init gets called at the initialization of the Dropzone itself, and then you set up the complete event handler to do something when each file that's uploaded is complete. But, what mechanism is the user given to allow the program to know when he's dropped all the files he's intended to drop? If you are assuming that he/she will do a batch drop (i.e., drop onto the Dropzone 2-whatever number of files, at once, in one drop action), then the following code could/possibly should work:

Dropzone.options.filedrop = {
    maxFilesize: 4096,
    init: function () {
        var totalFiles = 0,
            completeFiles = 0;
        this.on("addedfile", function (file) {
            totalFiles += 1;
        });
        this.on("removed file", function (file) {
            totalFiles -= 1;
        });
        this.on("complete", function (file) {
            completeFiles += 1;
            if (completeFiles === totalFiles) {
                doSomething();
            }
        });
    }
};

Basically, you watch any time someone adds/removes files from the Dropzone, and keep a count in closure variables. Then, when each file download is complete, you increment the completeFiles progress counter var, and see if it now equals the totalCount you'd been watching and updating as the user placed things in the Dropzone. (Note: never used the plug-in/JS lib., so this is best guess as to what you could do to get what you want.)

Uninstall the Angular CLI and install the latest version of it.

I came up with this importable module function. It uses the gmail email server in this example. Its split into header and message so you can clearly see whats going on:

import smtplib

def send_alert(subject=""):

    to = ['[email protected]', 'email2@another_email.com', '[email protected]']
    gmail_user = '[email protected]'
    gmail_pwd = 'my_pass'
    smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
    smtpserver.ehlo()
    smtpserver.starttls()
    smtpserver.ehlo
    smtpserver.login(gmail_user, gmail_pwd)
    header = 'To:' + ", ".join(to) + '\n' + 'From: ' + gmail_user + '\n' + 'Subject: ' + subject + '\n'
    msg = header + '\n' + subject + '\n\n'
    smtpserver.sendmail(gmail_user, to, msg)
    smtpserver.close()

This way works fine for me:

var request = new RestSharp.RestRequest("RESOURCE", RestSharp.Method.POST) { RequestFormat = RestSharp.DataFormat.Json }
                .AddBody(BODY);

var response = Client.Execute(request);

// Handle response errors
HandleResponseErrors(response);

if (Errors.Length == 0)
{ }
else
{ }

Hope this helps! (Although it is a bit late)

Hello everyone I tried another way to combine background-image and background-color together:

HTML

<article><canvas id="color"></canvas></article>

CSS

article {
  height: 490px;
  background: url("Your IMAGE") no-repeat center cover;
  opacity:1;
} 

canvas{
  width: 100%; 
  height: 490px; 
  opacity: 0.9;
}

JAVASCRIPT

window.onload = init();

var canvas, ctx;

function init(){
  canvas = document.getElementeById('color'); 
  ctx = canvas.getContext('2d'); 
  ctx.save();  
  ctx.fillstyle = '#00833d'; 
  ctx.fillRect(0,0,490,490);ctx.restore();
}

Please let me know if it worked for you Thanks

The validate_required function seems to expect an HTML form control (e.g, text input field) as first argument, and check whether there is a value there at all. That is not what you want in this case.

Also, when you write ['password'].value, you create a new array of length one, containing the string 'password', and then read the non-existing property "value" from it, yielding the undefined value.

What you may want to try instead is:

if (password.value != cpassword.value) { cpassword.focus(); return false; }

(You also need to write the error message somehow, but I can't see from your code how that is done.).

In the Properties,

Go to Configuration Properties. In that go to C/C++ (or something like that). ,Then click General ,In that remove the check in the "Treat Warning As Errors" Check Box

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

If dir does not exist, create it:

boost::filesystem::create_directories(boost::filesystem::path(output_file).parent_path().string().c_str()); 

you can use glob function to do this. see the example

import cv2
import glob
for img in glob.glob("path/to/folder/*.png"):
    cv_img = cv2.imread(img)

I didn't find the above answers sufficiently explicit, and it took me some time to figure it out for myself. The most useful page I found was: http://www.lockergnome.com/web/2011/12/13/how-to-use-github-to-contribute-to-open-source-projects/

I'm on a Unix box, using the command line. I expect this will all work on a Mac command line. (Mac or Window GUI looks to be available at desktop.github.com but I haven't tested this, and don't know how transferable this will be to the GUI.)

Step 1: Create a Github account Step 2: Create a new repository, typically with a README and LICENCE file created in the process. Step 3: Install "git" software. (Links in answers above and online help at github should suffice to do these steps, so I don't provide detailed instructions.) Step 4: Tell git who you are:

git config --global user.name "<NAME>"
git config --global user.email "<email>"

I think the e-mail must be one of the addresses you have associated with the github account. I used the same name as I used in github, but I think (not sure) that this is not required. Optionally you can add caching of credentials, so you don't need to type in your github account name and password so often. https://help.github.com/articles/caching-your-github-password-in-git/

Create and navigate to some top level working directory:

mkdir <working>
cd <working>

Import the nearly empty repository from github:

git clone https://github.com/<user>/<repository>

This might ask for credentials (if github repository is not 'public'.) Move to directory, and see what we've done:

cd <repository>
ls -a
git remote -v

(The 'ls' and 'git remote' commands are optional, they just show you stuff) Copy the 10000 files and millions of lines of code that you want to put in the repository:

cp -R <path>/src .
git status -s

(assuming everything you want is under a directory named "src".) (The second command again is optional and just shows you stuff)

Add all the files you just copied to git, and optionally admire the the results:

git add src
git status -s

Commit all the changes:

git commit -m "<commit comment>"

Push the changes

git push origin master

"Origin" is an alias for your github repository which was automatically set up by the "git clone" command. "master" is the branch you are pushing to. Go look at github in your browser and you should see all the files have been added.

Optionally remove the directory you did all this in, to reclaim disk space:

cd ..
rm -r <working>

Open powershell in administrative mode and run the following command

Set-ExecutionPolicy RemoteSigned

Here is a solution that works with a dynamically defined type. The trick is creating the proper type of of array using Array.newInstance().

    public static <T> List<T> fromJsonList(String json, Class<T> clazz) {
    Object [] array = (Object[])java.lang.reflect.Array.newInstance(clazz, 0);
    array = gson.fromJson(json, array.getClass());
    List<T> list = new ArrayList<T>();
    for (int i=0 ; i<array.length ; i++)
        list.add(clazz.cast(array[i]));
    return list; 
}

In simple terms, it tells the compiler not to do any optimisation on a particular variable. Variables which are mapped to device register are modified indirectly by the device. In this case, volatile must be used.

this might be repetitive. I was trying to use pycharm to run flask - had anaconda 3, pycharm 2019.1.1 and windows 10. Created a new conda environment - it threw errors. Followed these steps -

1. Used the cmd to install python and flask after creating environment as suggested above.

2. Followed this answer.

3. As suggested above, went to Run -> Edit Configurations and changed the environment there as well as in (2).

Obviously kept the correct python interpreter (the one in the environment) everywhere.

I don't think that's possible, you could fake it with double parens ... just as long you don't need the arguments individually.

#define macro(ARGS) some_complicated (whatever ARGS)
// ...
macro((a,b,c))
macro((d,e))

you can easily do it with parseInt with format parameter.

Integer.parseInt("-FF", 16) ; // returns -255

javadoc Integer

use doesn't include anything. It just imports the specified namespace (or class) to the current scope

If you want the classes to be autoloaded - read about autoloading

For a css-only solution, try setting pointer-events: none on the input.

Would you be happy to make "my file.xls" active if it didn't affect the screen? Turning off screen updating is the way to achieve this, it also has performance improvements (significant if you are doing looping while switching around worksheets / workbooks).

The command to do this is:

    Application.ScreenUpdating = False

Don't forget to turn it back to True when your macros is finished.

If you can't change the source code, or redeploy, but you can examine the running processes on the computer use Process Explorer. I written a detailed description here.

It will list all executing dlls on the system, you may need to determine the process id of your running application, but that is usually not too difficult.

I've written a full description of how do this for a dll inside IIS - http://nodogmablog.bryanhogan.net/2016/09/locating-and-checking-an-executing-dll-on-a-running-web-server/

Context.getResources().getDimension(int id);

I'm sorry for my English but here's another reason :

I worked in some governmental organization and the number one reason to not use TABLE, is for disabled peoples. They use machines to "translate" web pages.

The problem is this "translation machine" can't read the website if it's done by TABLE. Why ? Because TABLE are for DATAS.

in fact, if you use TABLES, for each CELLS you have to specify some informations to let disabled people to know where they are in the TABLE. Imagine you have a big table and have to zoom to see only 1 cell in the screen : you have to know in which line/col you are.

So, DIV are used, and the disabled can simply read text, and don't get some weird informations about lines/cols when they don't have to be there.

I also prefer TABLE to make quick and easy templates, but I'm now used to CSS... it's powerful, but you really have to know what you are doing... :)

did you add the shebang to the top of the file?

#!/usr/bin/python

In the specific case where all the files have the same extension but with different suffix (say number of log file) you use the following:

scp [email protected]:/some/log/folder/some_log_file.* ./

This will copy all files named some_log_file from the given folder within the remote, i.e.- some_log_file.1 , some_log_file.2, some_log_file.3 ....

In addition to anyListOf above, you can always specify generics explicitly using this syntax:

when(mock.process(Matchers.<List<Bar>>any(List.class)));

Java 8 newly allows type inference based on parameters, so if you're using Java 8, this may work as well:

when(mock.process(Matchers.any()));

Remember that neither any() nor anyList() will apply any checks, including type or null checks. In Mockito 2.x, any(Foo.class) was changed to mean "any instanceof Foo", but any() still means "any value including null".

NOTE: The above has switched to ArgumentMatchers in newer versions of Mockito, to avoid a name collision with org.hamcrest.Matchers. Older versions of Mockito will need to keep using org.mockito.Matchers as above.

I think you'll get what you want with the -maxdepth 1 option, based on your current command structure. If not, you can try looking at the man page for find.

Relevant entry (for convenience's sake):

-maxdepth levels
          Descend at most levels (a non-negative integer) levels of direc-
          tories below the command line arguments.   `-maxdepth  0'  means
          only  apply the tests and actions to the command line arguments.

Your options basically are:

# Do NOT show hidden files (beginning with ".", i.e., .*):
find DirsRoot/* -maxdepth 0 -type f

Or:

#  DO show hidden files:
find DirsRoot/ -maxdepth 1 -type f

Math.Floor(): Returns the largest integer less than or equal to the specified double-precision floating-point number.

Math.Round(): Rounds a value to the nearest integer or to the specified number of fractional digits.

The easiest way is this.

byte[] bytes = rs.getBytes("my_field");

One line that always goes in my .vimrc:

set tags=./tags;/

This will look in the current directory for "tags", and work up the tree towards root until one is found. IOW, you can be anywhere in your source tree instead of just the root of it.

Just a follow-up to dbb's accepted answer: Rather than adding the immediate cell on the right to the selection, why not select a cell way off the working range (i.e. a dummy cell that you know the user will never need). In the following code cell ZZ1 is the dummy cell

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  Application.EnableEvents = False
  Union(Target, Me.Range("ZZ1")).Select
  Application.EnableEvents = True

  ' Respond to click/selection-change here

End Sub

Tonny Madsen said it right, but sometimes this is too simplistic.

What if you want to be more selective in your replacements since not all replacements are correct for what you're trying to do?

Here's how to get more granularity to do the replacements only in certain folders, files, or instances:

First, do like he said:

• Click Search --> File... OR press Ctrl + H and choose the "File Search" tab.
• Enter text, file pattern and choose your Workspace or Working Set.

Then:

• Click Search
• When your results come up, make some folder, file, or instance selections by Ctrl + clicking on the ones you'd like to select. Ex: here's my selection. I've chosen 3 instances, 1 file, and 1 folder:

• Now, right-click on your selection and go to --> Replace Selected.... Here's a screenshot of that:

• Enter what you'd like to replace it "With". In my case you can see it says it is "Replacing 190 matches in 4 files". Now click OK.

Voilà!

References:

• Here's the tutorial I came across that taught me this: http://www.avajava.com/tutorials/lessons/how-do-i-do-a-find-and-replace-in-multiple-files-in-eclipse.html?page=2

The answer of shimi_tap is enough. What to be remembered is that choosing only what you need. Choose from {icon, name, theme, label}. I added tools:replace="android:icon,android:theme", it does not work. I added tools:replace="android:icon,android:theme,android:label,android:name", it does not work. It works when I added tools:replace="android:icon,android:theme,android:label". So find out what the conflict exactly is in your manifest files.

Install a stable version instead of the latest one, I have downgrade my version to node-v0.10.29-x86.msi from 'node-v0.10.33-x86.msi' and it is working well for me!

(at least) for Django 1.8:

If you use

if settings.DEBUG:
  urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))

as described above, make sure that no "catch all" url pattern, directing to a default view, comes before that in urlpatterns = []. As .append will put the added scheme to the end of the list, it will of course only be tested if no previous url pattern matches. You can avoid that by using something like this where the "catch all" url pattern is added at the very end, independent from the if statement:

if settings.DEBUG:
    urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))

urlpatterns.append(url(r'$', 'views.home', name='home')),

I recommend lxml for parsing HTML. See "Parsing HTML" (on the lxml site).

In my experience Beautiful Soup messes up on some complex HTML. I believe that is because Beautiful Soup is not a parser, rather a very good string analyzer.

sometimes "something" may come not to stdout but to the stderr of the testing application, so here is the fix working more universal way:

if [[ $(partprobe ${1} 2>&1 | wc -c) -ne 0 ]]; then
    echo "require fixing GPT parititioning"
else
    echo "no GPT fix necessary"
fi

The task gives you all the goodness of the task API:

• Adding continuations (Task.ContinueWith)
• Waiting for multiple tasks to complete (either all or any)
• Capturing errors in the task and interrogating them later
• Capturing cancellation (and allowing you to specify cancellation to start with)
• Potentially having a return value
• Using await in C# 5
• Better control over scheduling (if it's going to be long-running, say so when you create the task so the task scheduler can take that into account)

Note that in both cases you can make your code slightly simpler with method group conversions:

DataInThread = new Thread(ThreadProcedure);
// Or...
Task t = Task.Factory.StartNew(ThreadProcedure);

#pragma mark - NSSecureCoding

The main purpose of "pragma" is for developer reference.

You can easily find a method/Function in a vast thousands of coding lines.

You aren't specifying the "height" of your html. When you're assigning a percentage in an element (i.e. divs) the css compiler needs to know the size of the parent element. If you don't assign that, you should see divs without height.

The most common solution is to set the following property in css:

html{
    height: 100%;
    margin: 0;
    padding: 0;
}

You are saying to the html tag (html is the parent of all the html elements) "Take all the height in the HTML document"

I hope I helped you. Cheers

Solution 1 - you need to change your backend to accept your incoming requests

Solution 2 - using Angular proxy see here

Please note this is only for ng serve, you can't use proxy in ng build

Note: the reason it's working via postman is postman doesn't send preflight requests while your browser does.

In Very simple words,

Blank is different than null.

null is purely database-related, whereas blank is validation-related(required in form).

If null=True, Django will store empty values as NULL in the database. If a field has blank=True, form validation will allow entry of an empty value. If a field has blank=False, the field will be required.

The question is you want write the name just one times.
I have an ider like this:

#define __ENUM(situation,num) \
    int situation = num;        const char * __##situation##_name = #situation;

    const struct {
        __ENUM(get_other_string, -203);//using a __ENUM Mirco make it ease to write, 
        __ENUM(get_negative_to_unsigned, -204);
        __ENUM(overflow,-205);
//The following two line showing the expanding for __ENUM
        int get_no_num = -201;      const char * __get_no_num_name = "get_no_num";
        int get_float_to_int = -202;        const char * get_float_to_int_name = "float_to_int_name";

    }eRevJson;
#undef __ENUM
    struct sIntCharPtr { int value; const char * p_name; };
//This function transform it to string.
    inline const char * enumRevJsonGetString(int num) {
        sIntCharPtr * ptr = (sIntCharPtr *)(&eRevJson);
        for (int i = 0;i < sizeof(eRevJson) / sizeof(sIntCharPtr);i++) {
            if (ptr[i].value == num) {
                return ptr[i].p_name;
            }
        }
        return "bad_enum_value";
    }

it uses a struct to insert enum, so that a printer to string could follows each enum value define.

int main(int argc, char *argv[]) {  
    int enum_test = eRevJson.get_other_string;
    printf("error is %s, number is %d\n", enumRevJsonGetString(enum_test), enum_test);

>error is get_other_string, number is -203

The difference to enum is builder can not report error if the numbers are repeated. if you don't like write number, __LINE__ could replace it:

#define ____LINE__ __LINE__
#define __ENUM(situation) \
    int situation = (____LINE__ - __BASELINE -2);       const char * __##situation##_name = #situation;
constexpr int __BASELINE = __LINE__;
constexpr struct {
    __ENUM(Sunday);
    __ENUM(Monday);
    __ENUM(Tuesday);
    __ENUM(Wednesday);
    __ENUM(Thursday);
    __ENUM(Friday);
    __ENUM(Saturday);
}eDays;
#undef __ENUM
inline const char * enumDaysGetString(int num) {
    sIntCharPtr * ptr = (sIntCharPtr *)(&eDays);
    for (int i = 0;i < sizeof(eDays) / sizeof(sIntCharPtr);i++) {
        if (ptr[i].value == num) {
            return ptr[i].p_name;
        }
    }
    return "bad_enum_value";
}
int main(int argc, char *argv[]) {  
    int d = eDays.Wednesday;
    printf("day %s, number is %d\n", enumDaysGetString(d), d);
    d = 1;
    printf("day %s, number is %d\n", enumDaysGetString(d), d);
}

>day Wednesday, number is 3 >day Monday, number is 1

The problem is that your REGX pattern will only match the input "0-9".

To meet your requirement (0-9999999), you should rewrite your regx pattern:

ng-pattern="/^[0-9]{1,7}$/"

My example:

HTML:

<div ng-app ng-controller="formCtrl">
  <form name="myForm" ng-submit="onSubmit()">
    <input type="number" ng-model="price" name="price_field" 
           ng-pattern="/^[0-9]{1,7}$/" required>
    <span ng-show="myForm.price_field.$error.pattern">Not a valid number!</span>
    <span ng-show="myForm.price_field.$error.required">This field is required!</span>
    <input type="submit" value="submit"/>
  </form>
</div>

JS:

function formCtrl($scope){
  $scope.onSubmit = function(){
    alert("form submitted");
  }
}

Here is a jsFiddle demo.

<table border="1" width="183" style='table-layout:fixed'>
  <col width="67">
  <col width="75">
  <col width="41">
  <tr>
    <td>First Column</td>
    <td>Second Column</td>
    <td>Third Column</td>
  </tr>
  <tr>
    <td>Row 1</td>
    <td>Text</td>
    <td align="right">1</td>
  </tr>
  <tr>
    <td>Row 2</td>
    <td>Abcdefg</td>
    <td align="right">123</td>
  </tr>
  <tr>
    <td>Row 3</td>
    <td>Abcdefghijklmnop</td>
    <td align="right">123456</td>
  </tr>
</table>

I know it's old school, but give that a try, it works.

may also want to add this:

<style>
  td {overflow:hidden;}
</style>

Of course, you'd put this in a separate linked stylesheet, and not inline... wouldn't you ;)

I have created some extension methods (below) so you don't have to worry if an IQueryable is already ordered or not. If you want to order by multiple properties just do it as follows:

// We do not have to care if the queryable is already sorted or not. 
// The order of the Smart* calls defines the order priority
queryable.SmartOrderBy(i => i.Property1).SmartOrderByDescending(i => i.Property2);

This is especially helpful if you create the ordering dynamically, f.e. from a list of properties to sort.

public static class IQueryableExtension
{
    public static bool IsOrdered<T>(this IQueryable<T> queryable) {
        if(queryable == null) {
            throw new ArgumentNullException("queryable");
        }

        return queryable.Expression.Type == typeof(IOrderedQueryable<T>);
    }

    public static IQueryable<T> SmartOrderBy<T, TKey>(this IQueryable<T> queryable, Expression<Func<T, TKey>> keySelector) {
        if(queryable.IsOrdered()) {
            var orderedQuery = queryable as IOrderedQueryable<T>;
            return orderedQuery.ThenBy(keySelector);
        } else {
            return queryable.OrderBy(keySelector);
        }
    }

    public static IQueryable<T> SmartOrderByDescending<T, TKey>(this IQueryable<T> queryable, Expression<Func<T, TKey>> keySelector) {
        if(queryable.IsOrdered()) {
            var orderedQuery = queryable as IOrderedQueryable<T>;
            return orderedQuery.ThenByDescending(keySelector);
        } else {
            return queryable.OrderByDescending(keySelector);
        }
    }
}

You can also cast a random value:

using System;

enum Test {
  Value1,
  Value2,
  Value3
}

class Program {
  public static void Main (string[] args) {
    var max = Enum.GetValues(typeof(Test)).Length;
    var value = (Test)new Random().Next(0, max - 1);
    Console.WriteLine(value);
  }
}

But you should use a better randomizer like the one in this library of mine.

a few small changes to make it responsive

<style type="text/css">
#wrap {
    width: 100%;
    margin: 0 auto;
    display: table;
}
#left_col {
   float:left;
   width:50%;
}
#right_col {
   float:right;
   width:50%;
}
@media only screen and (max-width: 480px){
    #left_col {
       width:100%;
    }
    #right_col {
       width:100%;
    }
}
</style>

<div id="wrap">
    <div id="left_col">
        ...
    </div>
    <div id="right_col">
        ...
    </div>
</div>

$("#" + $(this).attr("name")).hide();

If you are using xampp 7.3.9. socket already installed. You can check xampp\php\ext and you will get the php_socket.dll. if you get it go to your xampp control panel open php.ini file and remove (;) from extension=sockets.

I was able to achieve this result using the Jenkins Dynamic Parameter Plug-in. I used the Dynamic Choice Parameter option and, for the choices script, I used the following:

proc1 = ['/bin/bash', '-c', "/usr/bin/git ls-remote -h ssh://[email protected]/path/to/repo.git"].execute()
proc2 = ['/bin/bash', '-c', "awk '{print \$2}'"].execute()
proc3 = ['/bin/bash', '-c', "sed s%^refs/heads%origin%"].execute()

all = proc1 | proc2 | proc3
String result = all.text

String filename = "/tmp/branches.txt"
boolean success = new File(filename).write(result) 

def multiline = "cat /tmp/branches.txt".execute().text
def list = multiline.readLines()

It looks like the only way to achieve this is by setting

browser.display.focus_ring_width = 0

in about:config on a per browser basis.

Great job! I hacked together something similar, but had to run it separately. Having it just be part of the build process makes it so much simpler.

One item of note. I noticed that it doesn't copy over any of the include files that you mark as public. I've adapted what I had in my script to yours and it works fairly well. Paste the following to the end of your script.

if [ -d "${CURRENTCONFIG_DEVICE_DIR}/usr/local/include" ]
then
  mkdir -p "${CURRENTCONFIG_UNIVERSAL_DIR}/usr/local/include"
  cp "${CURRENTCONFIG_DEVICE_DIR}"/usr/local/include/* "${CURRENTCONFIG_UNIVERSAL_DIR}/usr/local/include"
fi

Modern cmake offers simpler ways to configure compilers to use a specific version of C++. The only thing anyone needs to do is set the relevant target properties. Among the properties supported by cmake, the ones that are used to determine how to configure compilers to support a specific version of C++ are the following:

• CXX_STANDARD sets the C++ standard whose features are requested to build the target. Set this as 11 to target C++11.

• CXX_EXTENSIONS, a boolean specifying whether compiler specific extensions are requested. Setting this as Off disables support for any compiler-specific extension.

To demonstrate, here is a minimal working example of a CMakeLists.txt.

cmake_minimum_required(VERSION 3.1)

project(testproject LANGUAGES CXX )

set(testproject_SOURCES
    main.c++
    )

add_executable(testproject ${testproject_SOURCES})

set_target_properties(testproject
    PROPERTIES
    CXX_STANDARD 11
    CXX_EXTENSIONS off
    )

When I'm working with csv files, I often use the pandas library. It makes things like this very easy. For example:

import pandas as pd

a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)

Some explanation follows. First, we read in the csv files:

>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a
   title  stage    jan    feb
0   darn  3.001  0.421  0.532
1     ok  2.829  1.036  0.751
2  three  1.115  1.146  2.921
>>> b
   title    mar    apr    may       jun  Unnamed: 5
0   darn  0.631  1.321  0.951    1.7510         NaN
1     ok  1.001  0.247  2.456    0.3216         NaN
2  three  0.285  1.283  0.924  956.0000         NaN

and we see there's an extra column of data (note that the first line of fileb.csv -- title,mar,apr,may,jun, -- has an extra comma at the end). We can get rid of that easily enough:

>>> b = b.dropna(axis=1)
>>> b
   title    mar    apr    may       jun
0   darn  0.631  1.321  0.951    1.7510
1     ok  1.001  0.247  2.456    0.3216
2  three  0.285  1.283  0.924  956.0000

Now we can merge a and b on the title column:

>>> merged = a.merge(b, on='title')
>>> merged
   title  stage    jan    feb    mar    apr    may       jun
0   darn  3.001  0.421  0.532  0.631  1.321  0.951    1.7510
1     ok  2.829  1.036  0.751  1.001  0.247  2.456    0.3216
2  three  1.115  1.146  2.921  0.285  1.283  0.924  956.0000

and finally write this out:

>>> merged.to_csv("output.csv", index=False)

producing:

title,stage,jan,feb,mar,apr,may,jun
darn,3.001,0.421,0.532,0.631,1.321,0.951,1.751
ok,2.829,1.036,0.751,1.001,0.247,2.456,0.3216
three,1.115,1.146,2.921,0.285,1.283,0.924,956.0

There is two way for hide a element

1. Use the "hidden" html attribute But in angular you can bind it with one or more fields like this :

   <input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden">

2.Better way of doing this is to use " *ngIf " directive like this :

<input class="txt" type="password" [(ngModel)]="input_pw" *ngIf="!isHidden">

Now why this is a better way because it doesn't just hide the element, it will removes it from the html code so this will help your page to render.

Like this: (Assuming a typed dataset)

someTable.Select(r => new { r.attribute1_name, r.attribute2_name }).Distinct();

I faced the same problem when import C++ Dll in .Net Framework +4, I unchecked Project->Properties->Build->Prefer 32-bit and it solved for me.

As an additional note, there is no need for the for loop because of R's vectorization.

This:

P <- 243.51
t <- 31 / 365
n <- 365

for (r in seq(0.15, 0.22, by = 0.01))    
     A <- P * ((1 + (r/ n))^ (n * t))
     interest <- A - P
}

is equivalent to:

P <- 243.51
t <- 31 / 365
n <- 365
r <- seq(0.15, 0.22, by = 0.01)
A <- P * ((1 + (r/ n))^ (n * t))
interest <- A - P

Because r is a vector, the expression above containing it is performed for all values of the vector.

One simple solution:

cond1 <- df$sub == 1 & df$day == 2

cond2 <- df$sub == 3 & df$day == 4

df <- df[!(cond1 | cond2),]

I believe SET is ANSI standard whereas the SELECT is not. Also note the different behavior of SET vs. SELECT in the example below when a value is not found.

declare @var varchar(20)
set @var = 'Joe'
set @var = (select name from master.sys.tables where name = 'qwerty')
select @var /* @var is now NULL */

set @var = 'Joe'
select @var = name from master.sys.tables where name = 'qwerty'
select @var /* @var is still equal to 'Joe' */

put .gitignore in your main catalog

git status (you will see which files you can commit)

I was able to solve the problem by using chown on the folder:

sudo chown -R "$USER":admin /usr/local

Also you'll (most probably) have to do the same on /Library/Caches/Homebrew:

sudo chown -R "$USER":admin /Library/Caches/Homebrew

Apparently I had used sudo before in a way that altered my folder permission on /usr/local, from here on forward all installations with brew have proven to be successful.

I want to extend this topic/answers with the following. As someone mentioned, this auto-generated AssemblyInfo can be an obstacle for the external tools. In my case, using FinalBuilder, I had an issue that AssemblyInfo wasn't getting updated by build action. Apparently, FinalBuilder relies on ~proj file to find location of the AssemblyInfo. I thought, it was looking anywhere under project folder. No. So, changing this

<PropertyGroup>
   <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
</PropertyGroup> 

did only half the job, it allowed custom assembly info if built by VS IDE/MS Build. But I needed FinalBuilder do it too without manual manipulations to assembly info file. I needed to satisfy all programs, MSBuild/VS and FinalBuilder.

I solved this by adding an entry to the existing ItemGroup

<ItemGroup>
   <Compile Remove="Common\**" />
   <Content Remove="Common\**" />
   <EmbeddedResource Remove="Common\**" />
   <None Remove="Common\**" />
   <!-- new added item -->
   <None Include="Properties\AssemblyInfo.cs" />
</ItemGroup>

Now, having this item, FinalBuilder finds location of AssemblyInfo and modifies the file. While action None allows MSBuild/DevEnv ignore this entry and no longer report an error based on Compile action that usually comes with Assembly Info entry in proj files.

C:\Program Files\dotnet\sdk\2.0.2\Sdks\Microsoft.NET.Sdk\build\Microsoft.NET.Sdk.DefaultItems.targets(263,5): error : Duplicate 'Compile' items were included. The .NET SDK includes 'Compile' items from your project directory by default. You can either remove these items from your project file, or set the 'EnableDefaultCompileItems' property to 'false' if you want to explicitly include them in your project file. For more information, see https://aka.ms/sdkimplicititems. The duplicate items were: 'AssemblyInfo.cs'

Add your C:\WinPython-64bit-3.4.4.1\python_***\Scripts folder to your system PATH variable by doing the following:

1. Select Start, select Control Panel. double click System, and select the Advanced tab.

2. Click Environment Variables. ...

3. In the Edit System Variable (or New System Variable) window, specify the value of the PATH environment variable. ...

4. Reopen Command prompt window

You can scroll to the element by using javascript through the execute_javascript method. For example here is how I do it using SeleniumLibrary on Robot Framework:

web_element = self.selib.find_element(locator)
self.selib.execute_javascript(
    "ARGUMENTS",
    web_element,
    "JAVASCRIPT",
    'arguments[0].scrollIntoView({behavior: "instant", block: "start", inline: "start"});'
)

In a nutshell, sys.argv is a list of the words that appear in the command used to run the program. The first word (first element of the list) is the name of the program, and the rest of the elements of the list are any arguments provided. In most computer languages (including Python), lists are indexed from zero, meaning that the first element in the list (in this case, the program name) is sys.argv[0], and the second element (first argument, if there is one) is sys.argv[1], etc.

The test len(sys.argv) >= 2 simply checks wither the list has a length greater than or equal to 2, which will be the case if there was at least one argument provided to the program.

If you want to click on all elements selected by some class, you can use this example (used on last.fm on the Loved tracks page to Unlove all).

var divs = document.querySelectorAll('.love-button.love-button--loved'); 

for (i = 0; i < divs.length; ++i) {
  divs[i].click();
};

With ES6 and Babel (cannot be run in the browser console directly)

[...document.querySelectorAll('.love-button.love-button--loved')]
   .forEach(div => { div.click(); })

The difference is the value returned to the environment is 0 in the former case and 1 in the latter case:

$ ./prog_with_exit_0
$ echo $?
0
$

and

$ ./prog_with_exit_1
$ echo $?
1
$

Also note that the macros value EXIT_SUCCESS and EXIT_FAILURE used as an argument to exit function are implementation defined but are usually set to respectively 0 and a non-zero number. (POSIX requires EXIT_SUCCESS to be 0). So usually exit(0) means a success and exit(1) a failure.

An exit function call with an argument in main function is equivalent to the statement return with the same argument.

Separate it into 2 triggers. One for the deletion and one for the insertion\ update.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

If you are using Eclipse IDE then go inside Window menu and select preferences and there you search for installed JREs and select the JRE you need to build the project

If you still can not unmount or remount your device after stopping all services and processes with open files, then there may be a swap file or swap partition keeping your device busy. This will not show up with fuser or lsof. Turn off swapping with:

sudo swapoff -a

You could check beforehand and show a summary of any swap partitions or swap files with:

swapon -s

or:

cat /proc/swaps

As an alternative to using the command sudo swapoff -a, you might also be able to disable the swap by stopping a service or systemd unit. For example:

sudo systemctl stop dphys-swapfile

or:

sudo systemctl stop var-swap.swap

In my case, turning off swap was necessary, in addition to stopping any services and processes with files open for writing, so that I could remount my root partition as read only in order to run fsck on my root partition without rebooting. This was necessary on a Raspberry Pi running Raspbian Jessie.

For anyone who tried everything without luck, this is the only thing that got it working for me. For the multiline labels inside cell, try adding this magic line:

When you killed the session, the session hangs around for a while in "KILLED" status while Oracle cleans up after it.

If you absolutely must, you can kill the OS process as well (look up v$process.spid), which would release any locks it was holding on to.

See this for more detailed info.

As has been mentioned, as of PHP 5.6+ you can (should!) use the ... token (aka "splat operator", part of the variadic functions functionality) to easily call a function with an array of arguments:

<?php
function variadic($arg1, $arg2)
{
    // Do stuff
    echo $arg1.' '.$arg2;
}

$array = ['Hello', 'World'];

// 'Splat' the $array in the function call
variadic(...$array);

// 'Hello World'

Note: array items are mapped to arguments by their position in the array, not their keys.

As per CarlosCarucce's comment, this form of argument unpacking is the fastest method by far in all cases. In some comparisons, it's over 5x faster than call_user_func_array.

Aside

Because I think this is really useful (though not directly related to the question): you can type-hint the splat operator parameter in your function definition to make sure all of the passed values match a specific type.

(Just remember that doing this it MUST be the last parameter you define and that it bundles all parameters passed to the function into the array.)

This is great for making sure an array contains items of a specific type:

<?php

// Define the function...

function variadic($var, SomeClass ...$items)
{
    // $items will be an array of objects of type `SomeClass`
}

// Then you can call...

variadic('Hello', new SomeClass, new SomeClass);

// or even splat both ways

$items = [
    new SomeClass,
    new SomeClass,
];

variadic('Hello', ...$items);

You can't set CURRENT_TIMESTAMP as default value with DATETIME.

But you can do it with TIMESTAMP.

See the difference here.

Words from this blog

The DEFAULT value clause in a data type specification indicates a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression.

This means, for example, that you cannot set the default for a date column to be the value of a function such as NOW() or CURRENT_DATE.

The exception is that you can specify CURRENT_TIMESTAMP as the default for a TIMESTAMP column.

In your button1_click function you are using '==' for button2.Enabled == true;

This should be button2.Enabled = true;

There's a difference between an empty string (email != "") and NULL. NULL is null and an Empty string is something.

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

Another option is to use one of my personal favorite CSS tools: box-shadow.

A box shadow is really a drop-shadow on the node. It looks like this:

-moz-box-shadow: 1px 2px 3px rgba(0,0,0,.5);
-webkit-box-shadow: 1px 2px 3px rgba(0,0,0,.5);
box-shadow: 1px 2px 3px rgba(0,0,0,.5);

The arguments are:

1px: Horizontal offset of the effect. Positive numbers shift it right, negative left.
2px: Vertical offset of the effect. Positive numbers shift it down, negative up.
3px: The blur effect.  0 means no blur.
color: The color of the shadow.

So, you could leave your current design, and add a box-shadow like:

box-shadow: 0px -2px 2px rgba(34,34,34,0.6);

This should give you a 'blurry' top-edge.

The problem with not passing over the content-type on a GET message is that sure the content-type is irrelevant because the server side determines the content anyway. The problem that I have encountered is that there are now a lot of places that set up their webservices to be smart enough to pick up the content-type that you pass and return the response in the 'type' that you request. Eg. we are currently messaging with a place that defaults to JSON, however, they have set their webservice up so that if you pass a content-type of xml they will then return xml rather than their JSON default. Which I think going forward is a great idea

git commit -a -m "Your commit message here"

will quickly commit all changes with the commit message. Git commit "title" and "description" (as you call them) are nothing more than just the first line, and the rest of the lines in the commit message, usually separated by a blank line, by convention. So using this command will just commit the "title" and no description.

If you want to commit a longer message, you can do that, but it depends on which shell you use.

In bash the quick way would be:

git commit -a -m $'Commit title\n\nRest of commit message...'

You can use Controls attribute

<video id="sampleMovie" src="HTML5Sample.mov" controls></video>

While using the EM_SETCUEBANNER message is probably simplest, one thing I do not like is that the placeholder text disappears when the control gets focus. That's a pet peeve of mine when I'm filling out forms. I have to click off of it to remember what the field is for.

So here is another solution for WinForms. It overlays a Label on top of the control, which disappears only when the user starts typing.

It's certainly not bulletproof. It accepts any Control, but I've only tested with a TextBox. It may need modification to work with some controls. The method returns the Label control in case you need to modify it a bit in a specific case, but that may never be needed.

Use it like this:

SetPlaceholder(txtSearch, "Type what you're searching for");

Here is the method:

/// <summary>
/// Sets placeholder text on a control (may not work for some controls)
/// </summary>
/// <param name="control">The control to set the placeholder on</param>
/// <param name="text">The text to display as the placeholder</param>
/// <returns>The newly-created placeholder Label</returns>
public static Label SetPlaceholder(Control control, string text) {
    var placeholder = new Label {
        Text = text,
        Font = control.Font,
        ForeColor = Color.Gray,
        BackColor = Color.Transparent,
        Cursor = Cursors.IBeam,
        Margin = Padding.Empty,

        //get rid of the left margin that all labels have
        FlatStyle = FlatStyle.System,
        AutoSize = false,

        //Leave 1px on the left so we can see the blinking cursor
        Size = new Size(control.Size.Width - 1, control.Size.Height),
        Location = new Point(control.Location.X + 1, control.Location.Y)
    };

    //when clicking on the label, pass focus to the control
    placeholder.Click += (sender, args) => { control.Focus(); };

    //disappear when the user starts typing
    control.TextChanged += (sender, args) => {
        placeholder.Visible = string.IsNullOrEmpty(control.Text);
    };

    //stay the same size/location as the control
    EventHandler updateSize = (sender, args) => {
        placeholder.Location = new Point(control.Location.X + 1, control.Location.Y);
        placeholder.Size = new Size(control.Size.Width - 1, control.Size.Height);
    };

    control.SizeChanged += updateSize;
    control.LocationChanged += updateSize;

    control.Parent.Controls.Add(placeholder);
    placeholder.BringToFront();

    return placeholder;
}

I don't like and understand things, which can be explained visually, by words.

Here's a simple function:

function setParent(el, newParent)
{
    newParent.appendChild(el);
}

el's childNodes are the elements to be moved, newParent is the element el will be moved to, so you would execute the function like:

var l = document.getElementById('old-parent').childNodes.length;
var a = document.getElementById('old-parent');
var b = document.getElementById('new-parent');
for (var i = l; i >= 0; i--)
{
    setParent(a.childNodes[0], b);
}

Here is the Demo

Tell Apache to deliver HTML with GZip - this generally reduces the response size by about 70%. (If you use Apache, the module configuring gzip depends on your version: Apache 1.3 uses mod_gzip while Apache 2.x uses mod_deflate.)

Use the following snippet to remove white-spaces from the HTML with the help ob_start's buffer:

<?php

function sanitize_output($buffer) {

    $search = array(
        '/\>[^\S ]+/s',     // strip whitespaces after tags, except space
        '/[^\S ]+\</s',     // strip whitespaces before tags, except space
        '/(\s)+/s',         // shorten multiple whitespace sequences
        '/<!--(.|\s)*?-->/' // Remove HTML comments
    );

    $replace = array(
        '>',
        '<',
        '\\1',
        ''
    );

    $buffer = preg_replace($search, $replace, $buffer);

    return $buffer;
}

ob_start("sanitize_output");

My favorite "swiss knife" Beyond Compare from http://www.scootersoftware.com/

I wasn't using Azure, but I got the same error locally. Using <customErrors mode="Off" /> seemed to have no effect, but checking the Application logs in Event Viewer revealed a warning from ASP.NET which contained all the detail I needed to resolve the issue.

I am facing the same issue, I am able to hide android keyboard even focus is in textbox by just adding one css property

<input type="text" style="pointer-events:none" />

and it works fine...

And for all input and select:

$("input[required], select[required]").attr("oninvalid", "this.setCustomValidity('Required!')");
$("input[required], select[required]").attr("oninput", "setCustomValidity('')");

Joking aside, if you're only expecting your input integer to be a zero or a one, you should really be checking that this is the case.

int yourInteger = whatever;
bool yourBool;
switch (yourInteger)
{
    case 0: yourBool = false; break;
    case 1: yourBool = true;  break;
    default:
        throw new InvalidOperationException("Integer value is not valid");
}

The out-of-the-box Convert won't check this; nor will yourInteger (==|!=) (0|1).

I'm going to say right off the bat that you will not be able to achieve the look they have with radio buttons with strictly CSS.

You could, however, stick to the list style in the example you posted and replace the anchors with clickable spans that would trigger a javascript event that would in turn save that rating to your database via ajax.

If you went that route you would probably also want to save a cookie to the users machine so that they could not submit over and over again to your database. That would prevent them from submitting more than once at least until they deleted their cookies.

But of course there are many ways to address this problem. This is just one of them. Hope that helps.

Maybe this is useful to anyone in the future, I have implemented a custom Authorize Attribute like this:

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class ClaimAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    private readonly string _claim;

    public ClaimAuthorizeAttribute(string Claim)
    {
        _claim = Claim;
    }

    public void OnAuthorization(AuthorizationFilterContext context)
    {
        var user = context.HttpContext.User;
        if(user.Identity.IsAuthenticated && user.HasClaim(ClaimTypes.Name, _claim))
        {
            return;
        }

        context.Result = new ForbidResult();
    }
}

There are several methods, two of which are as follows. Provide a custom installer or a setup project.

Here is how to create a custom installer

[RunInstaller(true)]
public class MyInstaller : Installer
{
    public HelloInstaller()
        : base()
    {
    }

    public override void Commit(IDictionary mySavedState)
    {
        base.Commit(mySavedState);
        System.IO.File.CreateText("Commit.txt");

People used to GCC and Clang are spoiled. It's not all that good out there.

I have been pretty horrified over the years by the staggeringly aged compilers I've been required to use. Often companies and managers adopt an ultra-conservative approach to changing compilers and will not even test if a new compiler ( with better standards compliance and code optimization ) will work in their system. The practical reality for working developers is that when you're coding you need to cover your bases and, unfortunately, casting mallocs is a good habit if you cannot control what compiler may be applied to your code.

I would also suggest that many organizations apply a coding standard of their own and that that should be the method people follow if it is defined. In the absence of explicit guidance I tend to go for most likely to compile everywhere, rather than slavish adherence to a standard.

The argument that it's not necessary under current standards is quite valid. But that argument omits the practicalities of the real world. We do not code in a world ruled exclusively by the standard of the day, but by the practicalities of what I like to call "local management's reality field". And that's bent and twisted more than space time ever was. :-)

YMMV.

I tend to think of casting malloc as a defensive operation. Not pretty, not perfect, but generally safe. ( Honestly, if you've not included stdlib.h then you've way more problems than casting malloc ! ).

This answer is like rodrigob's except without the BOOST_FOREACH. You can use c++'s range based for instead.

#include <map>
#include <boost/range/adaptor/map.hpp>
#include <iostream>

template <typename K, typename V>
void printKeys(std::map<K,V> map){
     for(auto key : map | boost::adaptors::map_keys){
          std::cout << key << std::endl;
     }
}

You can try this:

<div ng-app="app">
    <div ng-controller="AppCtrl">
        <a my-dir ng-repeat="user in users" ng-click="fxn()">{{user.name}}</a>
    </div>
</div>

<script>
var app = angular.module('app', []);

function AppCtrl($scope) {
        $scope.users = [{ name: 'John', id: 1 }, { name: 'anonymous' }];
        $scope.fxn = function () {
            alert('It works');
        };
    }

app.directive("myDir", function ($compile) {
    return {
        scope: {ngClick: '='}
    };
});
</script>

I was searching for this answer for a while. Now I got it in the official gulp documentation.

If you want to perform a gulp task when the last one is complete, you have to return a stream:

gulp.task('wiredep', ['dev-jade'], function () {_x000D_
    var stream = gulp.src(paths.output + '*.html')_x000D_
        .pipe($.wiredep())_x000D_
        .pipe(gulp.dest(paths.output));_x000D_
_x000D_
    return stream; // execute next task when this is completed_x000D_
});_x000D_
_x000D_
// First will execute and complete wiredep task_x000D_
gulp.task('prod-jade', ['wiredep'], function() {_x000D_
    gulp.src(paths.output + '**/*.html')_x000D_
        .pipe($.minifyHtml())_x000D_
        .pipe(gulp.dest(paths.output));_x000D_
});

This is directly from http://www.programcreek.com/2011/10/java-class-instance-initializers/

1. Execution Order

Look at the following class, do you know which one gets executed first?

public class Foo {
 
    //instance variable initializer
    String s = "abc";
 
    //constructor
    public Foo() {
        System.out.println("constructor called");
    }
 
    //static initializer
    static {
        System.out.println("static initializer called");
    }
 
    //instance initializer
    {
        System.out.println("instance initializer called");
    }
 
    public static void main(String[] args) {
        new Foo();
        new Foo();
    }
}

Output:

static initializer called

instance initializer called

constructor called

instance initializer called

constructor called

2. How do Java instance initializer work?

The instance initializer above contains a println statement. To understand how it works, we can treat it as a variable assignment statement, e.g., b = 0. This can make it more obvious to understand.

Instead of

int b = 0, you could write

int b;
b = 0;

Therefore, instance initializers and instance variable initializers are pretty much the same.

3. When are instance initializers useful?

The use of instance initializers are rare, but still it can be a useful alternative to instance variable initializers if:

1. Initializer code must handle exceptions
2. Perform calculations that can’t be expressed with an instance variable initializer.

Of course, such code could be written in constructors. But if a class had multiple constructors, you would have to repeat the code in each constructor.

With an instance initializer, you can just write the code once, and it will be executed no matter what constructor is used to create the object. (I guess this is just a concept, and it is not used often.)

Another case in which instance initializers are useful is anonymous inner classes, which can’t declare any constructors at all. (Will this be a good place to place a logging function?)

Thanks to Derhein.

Also note that Anonymous classes that implement interfaces [1] have no constructors. Therefore instance initializers are needed to execute any kinds of expressions at construction time.

It's easy lol (works in all browsers [except opera]):

$('input[type=file]').each(function(){
    $(this).after($(this).clone(true)).remove();
});

tl;dr Set the editor to something nicer, like Sublime or Atom

Here nice is used in the meaning of an editor you like or find more user friendly.

The underlying problem is that Git by default uses an editor that is too unintuitive to use for most people: Vim. Now, don't get me wrong, I love Vim, and while you could set some time aside (like a month) to learn Vim and try to understand why some people think Vim is the greatest editor in existence, there is a quicker way of fixing this problem :-)

The fix is not to memorize cryptic commands, like in the accepted answer, but configuring Git to use an editor that you like and understand! It's really as simple as configuring either of these options

1. the git config setting core.editor (per project, or globally)
2. the VISUAL or EDITOR environment variable (this works for other programs as well)

I'll cover the first option for a couple of popular editors, but GitHub has an excellent guide on this for many editors as well.

To use Atom

Straight from its docs, enter this in a terminal: git config --global core.editor "atom --wait"

Git normally wait for the editor command to finish, but since Atom forks to a background process immediately, this won't work, unless you give it the --wait option.

To use Sublime Text

For the same reasons as in the Atom case, you need a special flag to signal to the process that it shouldn't fork to the background:

git config --global core.editor "subl -n -w"

you should use :

ln -s /home/jake/doc/test/2000/something xxx

Try this: only works on console, not in NetBeans integrated console.

public static void cls(){
    try {

     if (System.getProperty("os.name").contains("Windows"))
         new ProcessBuilder("cmd", "/c", 
                  "cls").inheritIO().start().waitFor();
     else
         Runtime.getRuntime().exec("clear");
    } catch (IOException | InterruptedException ex) {}
}

Use the dec argument to set "," as the decimal point by adding:

 ce <- read.table("file.txt", header = TRUE, dec = ",")

Ok, so here was my process:

keytool -list -v -keystore permanent.jks - got me the alias.

keytool -export -alias alias_name -file certificate_name -keystore permanent.jks - got me the certificate to import.

Then I could import it with the keytool:

keytool -import -alias alias_name -file certificate_name -keystore keystore location

As @Christian Bongiorno says the alias can't already exist in your keystore.

Heap is just an area where memory is allocated or deallocated without any order. This happens when one creates an object using the new operator or something similar. This is opposed to stack where memory is deallocated on the first in last out basis.

Probably because you forgot to implement the solution in the accepted answer. That's the code that makes trim() work.

update

This answer only applies to older browsers. Newer browsers apparently support trim() natively.

Could not get this to work until I put Authorization in single quotes:

axios.get(URL, { headers: { 'Authorization': AuthStr } })

I know its late but it might be helpful for those that want other ways. Another way array key=>values can be stored is by using an array method called map(); (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map) you can use arrow function too

 
    var countries = ['Canada','Us','France','Italy'];  

    // Arrow Function  

    countries.map((value, key) => key+ ' : ' + value );  

    // Anonomous Function  

    countries.map(function(value, key){  

         return key + " : " + value;  

    });  

    

Summarizing, both the Build and Project\Build\Platform has to be set to x64 in order to successfully install 64 bit service on 64 bit system.

Here's what I use:

function strhex($string) {
  $hexstr = unpack('H*', $string);
  return array_shift($hexstr);
}

Constructor overloading is like method overloading. Constructors can be overloaded to create objects in different ways.

The compiler differentiates constructors based on how many arguments are present in the constructor and other parameters like the order in which the arguments are passed.

eburgos, I've modified your code slightly because when you have multiple datatables in your dataset it was just overwriting them in the spreadsheet so you were only left with one sheet in the workbook. I basically just moved the part where the workbook is created out of the loop. Here is the updated code.

private void ExportDSToExcel(DataSet ds, string destination)
{
    using (var workbook = SpreadsheetDocument.Create(destination, DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook))
    {
        var workbookPart = workbook.AddWorkbookPart();
        workbook.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook();
        workbook.WorkbookPart.Workbook.Sheets = new DocumentFormat.OpenXml.Spreadsheet.Sheets();

        uint sheetId = 1;

        foreach (DataTable table in ds.Tables)
        {
            var sheetPart = workbook.WorkbookPart.AddNewPart<WorksheetPart>();
            var sheetData = new DocumentFormat.OpenXml.Spreadsheet.SheetData();
            sheetPart.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet(sheetData);                

            DocumentFormat.OpenXml.Spreadsheet.Sheets sheets = workbook.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>();
            string relationshipId = workbook.WorkbookPart.GetIdOfPart(sheetPart);

            if (sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Count() > 0)
            {
                sheetId =
                    sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Select(s => s.SheetId.Value).Max() + 1;
            }

            DocumentFormat.OpenXml.Spreadsheet.Sheet sheet = new DocumentFormat.OpenXml.Spreadsheet.Sheet() { Id = relationshipId, SheetId = sheetId, Name = table.TableName };
            sheets.Append(sheet);

            DocumentFormat.OpenXml.Spreadsheet.Row headerRow = new DocumentFormat.OpenXml.Spreadsheet.Row();

            List<String> columns = new List<string>();
            foreach (DataColumn column in table.Columns)
            {
                columns.Add(column.ColumnName);

                DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
                cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
                cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(column.ColumnName);
                headerRow.AppendChild(cell);
            }

            sheetData.AppendChild(headerRow);

            foreach (DataRow dsrow in table.Rows)
            {
                DocumentFormat.OpenXml.Spreadsheet.Row newRow = new DocumentFormat.OpenXml.Spreadsheet.Row();
                foreach (String col in columns)
                {
                    DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
                    cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
                    cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(dsrow[col].ToString()); //
                    newRow.AppendChild(cell);
                }

                sheetData.AppendChild(newRow);
            }
        }
    }
}

With pivot_data as
(
select 
action, -- grouping column
view_edit -- spreading column
from tbl
)
select action, [view], [edit]
from   pivot_data
pivot  ( max(view_edit) for view_edit in ([view], [edit]) ) as p;

If you ignore the characteristics of both languages, how do you define "SPEED"? Which features should be in your benchmark and which do you want to omit?

For example:

• Does it count when Java executes an empty loop faster than Python?
• Or is Python faster when it notices that the loop body is empty, the loop header has no side effects and it optimizes the whole loop away?
• Or is that "a language characteristic"?
• Do you want to know how many bytecodes each language can execute per second?
• Which ones? Only the fast ones or all of them?
• How do you count the Java VM JIT compiler which turns bytecode into CPU-specific assembler code at runtime?
• Do you include code compilation times (which are extra in Java but always included in Python)?

Conclusion: Your question has no answer because it isn't defined what you want. Even if you made it more clear, the question will probably become academic since you will measure something that doesn't count in real life. For all of my projects, both Java and Python have always been fast enough. Of course, I would prefer one language over the other for a specific problem in a certain context.

I wrote a tree in C# to handle lookups on a table that a 6-segmented key with default cases (if key[0] doesn't exist, use the default case and continue). The lookups were done recursively. I tried a dictionary of dictionaries of dictionaries (etc) and it got way too complex very quickly.

I also wrote a formula evaluator in C# that evaluated equations stored in a tree to get the evaluation order correct. Granted this is likely a case of choosing the incorrect language for the problem but it was an interesting exercise.

I didn't see many examples of what people had done but rather libraries they had used. Hopefully this gives you something to think about.

You can just inject the DOCUMENT token into the constructor and use the same functions on it

import { Inject }  from '@angular/core';
import { DOCUMENT } from '@angular/common'; 

@Component({...})
export class AppCmp {
   constructor(@Inject(DOCUMENT) document) {
      document.getElementById('el');
   }
}

Or if the element you want to get is in that component, you can use template references.

You want to convert html (a byte-like object) into a string using .decode, e.g. html = response.read().decode('utf-8').

See Convert bytes to a Python String

I have the same problem now , I have foreign key and i need put it as nullable, to solve this problem you should put

    modelBuilder.Entity<Country>()
        .HasMany(c => c.Users)
        .WithOptional(c => c.Country)
        .HasForeignKey(c => c.CountryId)
        .WillCascadeOnDelete(false);

in DBContext class I am sorry for answer you very late :)

function isPrevDate() {
    alert("startDate is " + Startdate);
    if(Startdate.length != 0 && Startdate !='') {
        var start_date = Startdate.split('-');
        alert("Input date: "+ start_date);
        start_date=start_date[1]+"/"+start_date[2]+"/"+start_date[0];
        alert("start date arrray format " + start_date);
        var a = new Date(start_date);
        //alert("The date is a" +a);
        var today = new Date();
        var day = today.getDate();
        var mon = today.getMonth()+1;
        var year = today.getFullYear();
        today = (mon+"/"+day+"/"+year);
        //alert(today);
        var today = new Date(today);
        alert("Today: "+today.getTime());
        alert("a : "+a.getTime());
        if(today.getTime() > a.getTime() )
        {
            alert("Please select Start date in range");
            return false;
        } else {
            return true;
        }
    }
}

the OOP way to do this in ES5 is to make that variable into a property using the this keyword.

function first(){
    this.nameContent=document.getElementById('full_name').value;
}

function second() {
    y=new first();
    alert(y.nameContent);
}

Simply, Dictionary<TKey,TValue> is a generic type, allowing:

• static typing (and compile-time verification)
• use without boxing

If you are .NET 2.0 or above, you should prefer Dictionary<TKey,TValue> (and the other generic collections)

A subtle but important difference is that Hashtable supports multiple reader threads with a single writer thread, while Dictionary offers no thread safety. If you need thread safety with a generic dictionary, you must implement your own synchronization or (in .NET 4.0) use ConcurrentDictionary<TKey, TValue>.

There is an hard limit on how much data can be stored in a single row of a mysql table, regardless of the number of columns or the individual column length.

As stated in the OFFICIAL DOCUMENTATION

The maximum row size constrains the number (and possibly size) of columns because the total length of all columns cannot exceed this size. For example, utf8 characters require up to three bytes per character, so for a CHAR(255) CHARACTER SET utf8 column, the server must allocate 255 × 3 = 765 bytes per value. Consequently, a table cannot contain more than 65,535 / 765 = 85 such columns.

Storage for variable-length columns includes length bytes, which are assessed against the row size. For example, a VARCHAR(255) CHARACTER SET utf8 column takes two bytes to store the length of the value, so each value can take up to 767 bytes.

How to convert decimal to hexadecimal in JavaScript

I wasn't able to find a brutally clean/simple decimal to hexadecimal conversion that didn't involve a mess of functions and arrays ... so I had to make this for myself.

function DecToHex(decimal) { // Data (decimal)

    length = -1;    // Base string length
    string = '';    // Source 'string'

    characters = [ '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' ]; // character array

    do { // Grab each nibble in reverse order because JavaScript has no unsigned left shift

        string += characters[decimal & 0xF];   // Mask byte, get that character
        ++length;                              // Increment to length of string

    } while (decimal >>>= 4); // For next character shift right 4 bits, or break on 0

    decimal += 'x'; // Convert that 0 into a hex prefix string -> '0x'

    do
        decimal += string[length];
    while (length--); // Flip string forwards, with the prefixed '0x'

    return (decimal); // return (hexadecimal);
}

/* Original: */

D = 3678;    // Data (decimal)
C = 0xF;    // Check
A = D;        // Accumulate
B = -1;        // Base string length
S = '';        // Source 'string'
H = '0x';    // Destination 'string'

do {
    ++B;
    A& = C;

    switch(A) {
        case 0xA: A='A'
        break;

        case 0xB: A='B'
        break;

        case 0xC: A='C'
        break;

        case 0xD: A='D'
        break;

        case 0xE: A='E'
        break;

        case 0xF: A='F'
        break;

        A = (A);
    }
    S += A;

    D >>>= 0x04;
    A = D;
} while(D)

do
    H += S[B];
while (B--)

S = B = A = C = D; // Zero out variables
alert(H);    // H: holds hexadecimal equivalent

You need:

record = record[:-1]

before the for loop.

This will set record to the current record list but without the last item. You may, depending on your needs, want to ensure the list isn't empty before doing this.

For image data, I find it simpler to use canvas.toBlob (asynchronous)

function b64toBlob(b64, onsuccess, onerror) {
    var img = new Image();

    img.onerror = onerror;

    img.onload = function onload() {
        var canvas = document.createElement('canvas');
        canvas.width = img.width;
        canvas.height = img.height;

        var ctx = canvas.getContext('2d');
        ctx.drawImage(img, 0, 0, canvas.width, canvas.height);

        canvas.toBlob(onsuccess);
    };

    img.src = b64;
}

var base64Data = 'data:image/jpg;base64,/9j/4AAQSkZJRgABAQA...';
b64toBlob(base64Data,
    function(blob) {
        var url = window.URL.createObjectURL(blob);
        // do something with url
    }, function(error) {
        // handle error
    });

sudo brew is no longer an option so if you install with brew at this point you're going to get 2 really obnoxious things: A: it likes to install into /usr/local/opts or according to this, /usr/local/shared. This isn't a big deal at first but i've had issues with node PATH especially when I installed lint. B: you're kind of stuck with sudo commands until you either uninstall and install it this way or you can get the stack from Bitnami

I recommend this method over the stack option because it's ready to go if you have multiple projects. If you go with the premade MEAN stack you'll have to set up virtual hosts in httpd.conf (more of a pain in this stack than XAMPP)plust the usual update your extra/vhosts.conf and /etc/hosts for every additional project, unless you want to repoint and restart your server when you get done updatading things.

I had the same issue and I solved it by using:

display: inline-block;

on the div in question.

You can use SwiftGif from this link

Usage:

imageView.loadGif(name: "jeremy")

Your second solution is probably the most correct. You should use the HTTP spec and mimetypes the way they were intended and upload the file via multipart/form-data. As far as handling the relationships, I'd use this process (keeping in mind I know zero about your assumptions or system design):

1. POST to /users to create the user entity.
2. POST the image to /images, making sure to return a Location header to where the image can be retrieved per the HTTP spec.
3. PATCH to /users/carPhoto and assign it the ID of the photo given in the Location header of step 2.

Be careful that this will create an "alternate reality" for people who have already fetch/pulled/cloned from the remote repository. But in fact, it's quite simple:

git reset HEAD^ # remove commit locally
git push origin +HEAD # force-push the new HEAD commit

If you want to still have it in your local repository and only remove it from the remote, then you can use:

git push origin +HEAD^:<name of your branch, most likely 'master'>

If using Sql Server Management Studio Designer just select both rows (Shift+Click) and Set Primary Key.

You'll need to download SLF4J's jars from the official site as either a zip (v1.7.4) or tar.gz (v1.7.4)

The download contains multiple jars based on how you want to use SLF4J. If you're simply trying to resolve the requirement of some other library (GWT, I assume) and don't really care about using SLF4J correctly, then I would probably pick the slf4j-api-1.7.4.jar since the Simple jar suggested by another answer does not contain, to my knowledge, the specific class you're looking for.

Something as simple as [a-z]+, or perhaps [\S]+, or even [a-zA-Z]+?

You should also be able to accomplish a similar thing using the premain method of a Java agent.

The manifest of the agent JAR file must contain the attribute Premain-Class. The value of this attribute is the name of the agent class. The agent class must implement a public static premain method similar in principle to the main application entry point. After the Java Virtual Machine (JVM) has initialized, each premain method will be called in the order the agents were specified, then the real application main method will be called. Each premain method must return in order for the startup sequence to proceed.

It is probably worth adding that an insert iterator of any kind (std::back_insert_iterator, std::front_insert_iterator, std::insert_iterator) is guaranteed to remain valid as long as all insertions are performed through this iterator and no other independent iterator-invalidating event occurs.

For example, when you are performing a series of insertion operations into a std::vector by using std::insert_iterator it is quite possible that these insertions will trigger vector reallocation, which will invalidate all iterators that "point" into that vector. However, the insert iterator in question is guaranteed to remain valid, i.e. you can safely continue the sequence of insertions. There's no need to worry about triggering vector reallocation at all.

This, again, applies only to insertions performed through the insert iterator itself. If iterator-invalidating event is triggered by some independent action on the container, then the insert iterator becomes invalidated as well in accordance with the general rules.

For example, this code

std::vector<int> v(10);
std::vector<int>::iterator it = v.begin() + 5;
std::insert_iterator<std::vector<int> > it_ins(v, it);

for (unsigned n = 20; n > 0; --n)
  *it_ins++ = rand();

is guaranteed to perform a valid sequence of insertions into the vector, even if the vector "decides" to reallocate somewhere in the middle of this process. Iterator it will obviously become invalid, but it_ins will continue to remain valid.

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default 

I created a module for this very thing that relies on the Angular-UI $modal service.

As of powershell 5.0, you can now use the -Depth parameter in Get-ChildItem!

You combine it with -Recurse to limit the recursion.
