I have the following add.. I need to separate out the dns suffix from the hostname.. and I only "know" the servers alias shortname... and want to know what the dns suffix is

#example:
#serveralias:     MyAppServer.us.fred.com
#actualhostname:  server01.us.fred.com 
#I "know":        "MyAppServer" .. I pass this on as an env var called myjumpbox .. this could also be $env:computername


$forname                 = $env:myjumpbox
$fqdn                    = [System.Net.Dns]::GetHostByName($forname).Hostname
$shortname               = $fqdn.split('.')[0]
$domainname              = $fqdn -split $fqdn.split('.')[0]+"."
$dnssuf                  = $domainname[1]  
" name parts are- alias: " + $forname + " actual hostname: " + $shortname + " suffix: " + $dnssuf

#returns

name parts are- alias: MyAppServer actual hostname: server01 suffix: us.fred.com

SSL certificates are bound to a 'common name', which is usually a fully qualified domain name but can be a wildcard name (eg. *.domain.com) or even an IP address, but it usually isn't.

In your case, you are accessing your LDAP server by a hostname and it sounds like your two LDAP servers have different SSL certificates installed. Are you able to view (or download and view) the details of the SSL certificate? Each SSL certificate will have a unique serial numbers and fingerprint which will need to match. I assume the certificate is being rejected as these details don't match with what's in your certificate store.

Your solution will be to ensure that both LDAP servers have the same SSL certificate installed.

BTW - you can normally override DNS entries on your workstation by editing a local 'hosts' file, but I wouldn't recommend this.

It is a little bit tricky, but try to follow the steps described in Installing Java on OS X 10.9 (Mavericks). Basically, you gonna have to update your alias to java.

Step by step:

After installing JDK 1.7, you will need to do the sudo ln -snf in order to change the link to current java. To do so, open Terminal and issue the command:

sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents \
/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

Note that the directory jdk1.7.0_51.jdk may change depending on the SDK version you have installed.

Now, you need to set JAVA_HOME to point to where jdk_1.7.0_xx.jdk was installed. Open again the Terminal and type:

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home"

You can add the export JAVA_HOME line above in your .bashrc file to have java permanently in your Terminal

Plain and simple:

plt.plot(x, y, 'r-', alpha=0.7)

(I know I add nothing new, but the straightforward answer should be visible).

This is an old question, but it's still one of the first results on Google. The fastest way to do this is to link MySQL directly to Excel using ODBC queries or MySQL For Excel. The latter was mentioned in a comment to the OP, but I felt it really deserved its own answer because exporting to CSV is not the most efficient way to achieve this.

ODBC Queries - This is a little bit more complicated to setup, but it's a lot more flexible. For example, the MySQL For Excel add-in doesn't allow you to use WHERE clauses in the query expressions. The flexibility of this method also allows you to use the data in more complex ways.

MySQL For Excel - Use this add-in if you don't need to do anything complex with the query or if you need to get something accomplished quickly and easily. You can make views in your database to workaround some of the query limitations.

It would be:

config/databases.yml
cache
log
data/sql
lib/filter/base
lib/form/base
lib/model/map
lib/model/om

or possibly even:

config/databases.yml
cache
log
data/sql
lib/*/base
lib/model/map
lib/model/om

in case that filter and form are the only directories in lib that do have a basesubdirectory that needs to be ignored (see it as an example of what you can do with the asterics).

An IFrame WILL "trigger" the spell checker (if it has content-editable set to true) just as a textfield, at least in Chrome.

Also remember that it must be:

#include "stdafx.h"
#include <iostream>

and not the other way around

#include <iostream>
#include "stdafx.h"

Worked for me!!! It was failing on CircleCI & on Jenkins as well.

If you're a Gradle User try add the following into your dependencies:

dependencies {
    //Other Dependencies >>

    //LOMBOK Dependencies
    annotationProcessor 'org.projectlombok:lombok'
    compileOnly 'org.projectlombok:lombok'
    testAnnotationProcessor 'org.projectlombok:lombok'
    testCompileOnly 'org.projectlombok:lombok'
}

Another way would be to catch the exeption:

def is_nat(npdatetime):
    try:
        npdatetime.strftime('%x')
        return False
    except:
        return True

var iframe = document.getElementById('youriframe');
iframe.src = iframe.src;

This will alert on leaving current page

<script type='text/javascript'>
function goodbye(e) {
    if(!e) e = window.event;
    //e.cancelBubble is supported by IE - this will kill the bubbling process.
    e.cancelBubble = true;
    e.returnValue = 'You sure you want to leave?'; //This is displayed on the dialog

    //e.stopPropagation works in Firefox.
    if (e.stopPropagation) {
        e.stopPropagation();
        e.preventDefault();
    }
}
window.onbeforeunload=goodbye; 

</script>

Simple function to alert contents of an object or an array .
Call this function with an array or string or an object it alerts the contents.

Function

function print_r(printthis, returnoutput) {
    var output = '';

    if($.isArray(printthis) || typeof(printthis) == 'object') {
        for(var i in printthis) {
            output += i + ' : ' + print_r(printthis[i], true) + '\n';
        }
    }else {
        output += printthis;
    }
    if(returnoutput && returnoutput == true) {
        return output;
    }else {
        alert(output);
    }
}

Usage

var data = [1, 2, 3, 4];
print_r(data);

purrr::flatten_*() is also a good option. the flatten_* functions add thin sanity checks and ensure type safety.

myList <- list('A'=1, 'B'=2, 'C'=3)

purrr::flatten_dbl(myList)
## [1] 1 2 3

There may be a limit depending on server and/or application configuration. For Example, check

/*
As close as I can get to Clear Screen

*/


void setup() {
// put your setup code here, to run once:
Serial.begin(115200);

}

void loop() {

Serial.println("This is Line ZERO ");

// put your main code here, to run repeatedly:

for (int i = 1; i < 37; i++)
{

 // Check and print Line
  if (i == 15)
  {
   Serial.println("Line 15");
  }

  else
   Serial.println(i);  //Prints line numbers   Delete i for blank line
  }

  delay(5000);  

  }

Bitcode (iOS, watchOS)

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Basically this concept is somewhat similar to java where byte code is run on different JVM's and in this case the bitcode is placed on iTune store and instead of giving the intermediate code to different platforms(devices) it provides the compiled code which don't need any virtual machine to run.

Thus we need to create the bitcode once and it will be available for existing or coming devices. It's the Apple's headache to compile an make it compatible with each platform they have.

Devs don't have to make changes and submit the app again to support new platforms.

Let's take the example of iPhone 5s when apple introduced x64 chip in it. Although x86 apps were totally compatible with x64 architecture but to fully utilise the x64 platform the developer has to change the architecture or some code. Once s/he's done the app is submitted to the app store for the review.

If this bitcode concept was launched earlier then we the developers doesn't have to make any changes to support the x64 bit architecture.

serialize it with System.Web.Script.Serialization.JavaScriptSerializer class and assign to javascript var

dummy sample:

<% var serializer = new System.Web.Script.Serialization.JavaScriptSerializer(); %>
var jsVariable = <%= serializer.Serialize(array) %>;

I beleive

$("#myElement").attr("title", "new title value")

or

$("#myElement").prop("title", "new title value")

should do the trick...

I think you can find all the core functions in the jQuery Docs, although I hate the formatting.

If you have Guava on your classpath, the following is a pretty readable alternative. Guava even has a fairly sensible custom List implementation for this case, so this shouldn't be inefficient.

for(char c : Lists.charactersOf(yourString)) {
    // Do whatever you want     
}

UPDATE: As @Alex noted, with Java 8 there's also CharSequence#chars to use. Even the type is IntStream, so it can be mapped to chars like:

yourString.chars()
        .mapToObj(c -> Character.valueOf((char) c))
        .forEach(c -> System.out.println(c)); // Or whatever you want

I believe it must work but any ways I'm not able to identify. Other approach can be,

<textarea (keyup)="emitWordCount(myModel)" [(ngModel)]="myModel"></textarea>


export class TextEditorComponent {
   @Output() countUpdate = new EventEmitter<number>();

   emitWordCount(model) {
       this.countUpdate.emit(
         (model.match(/\S+/g) || []).length);
       }
}

Try CSS.

If you want to remove Horizontal

overflow-x: hidden;

And if you want to remove Vertical

overflow-y: hidden;

You can put the file path to argument and create a list with all the filepaths and not put it the list manually. Then use a for loop and a reader. Example for txt files:

public static void main(String[] args) throws IOException{    
File[] files = new File(args[0].replace("\\", "\\\\")).listFiles(new FilenameFilter() { @Override public boolean accept(File dir, String name) { return name.endsWith(".txt"); } });
    ArrayList<String> filedir = new ArrayList<String>();
    String FILE_TEST = null;
    for (i=0; i<files.length; i++){
            filedir.add(files[i].toString());
            CSV_FILE_TEST=filedir.get(i) 

        try(Reader testreader = Files.newBufferedReader(Paths.get(FILE_TEST));
            ){
              //write your stuff
                 }}}

try download & run my bat code

======run 'cmd' as admin 2 use 'setx'===== setx scoop "C:\Users%username%\scoop" /M

echo %scoop%

setx scoopApps "%scoop%\apps" /M

You may not have the UDP port open/VPN-forwarded, it's port number 1433.

Despite client protocol name of "TCP/IP", mssql uses UDP for bitbanging.

d1G = delete to top including current line (vi)

JSONArray may be what you want.

String message;
JSONObject json = new JSONObject();
json.put("name", "student");

JSONArray array = new JSONArray();
JSONObject item = new JSONObject();
item.put("information", "test");
item.put("id", 3);
item.put("name", "course1");
array.put(item);

json.put("course", array);

message = json.toString();

// message
// {"course":[{"id":3,"information":"test","name":"course1"}],"name":"student"}

Be consistent and it doesn't matter which one. Also if for some reason you must interop with another program or tool using a certain DEBUG identifier it's easy to do

#ifdef THEIRDEBUG
#define MYDEBUG
#endif //and vice-versa

\begin{table}
 \caption{ Example of force text wrap}
 \begin{center}
  \begin{tabular}{|c|c|}
   \hline

   cell 3                &       cell 4 & & very big line that needs to be wrap. \\ \hline
   cell 5       &   cell 6 \\   \hline
  \end{tabular}
  \label{table:example}
 \end{center}
\end{table}

Remove the \bin, and also remove the ; at the end. After restart the cmd and run.

you can use moment.js to format with local time:

Date.prototype.toISOString = function () {
    return moment(this).format("YYYY-MM-DDTHH:mm:ss");
};

Remove all the properties with null and undefined

let obj = {
"id": 1,
"firstName": null,
"lastName": null,
"address": undefined,
"role": "customer",
"photo": "fb79fd5d-06c9-4097-8fdc-6cebf73fab26/fc8efe82-2af4-4c81-bde7-8d2f9dd7994a.jpg",
"location": null,
"idNumber": null,
};

   let result =  Object.entries(obj).reduce((a,[k,v]) => (v == null ? a : (a[k]=v, a)), {});
console.log(result)

Let's try this way:

select 
    a.ip, 
    a.os, 
    a.hostname, 
    a.port, 
    a.protocol, 
    b.state
from a
left join b 
    on a.ip = b.ip 
        and a.port = b.port /*if you has to filter by columns from right table , then add this condition in ON clause*/
where a.somecolumn = somevalue /*if you have to filter by some column from left table, then add it to where condition*/

So, in where clause you can filter result set by column from right table only on this way:

...
where b.somecolumn <> (=) null

Actually quite easy to roll your own tester, by abusing Java's method overload ability. Though I'm still curious if there is an official method in the sdk.

Example:

class Typetester {
    void printType(byte x) {
        System.out.println(x + " is an byte");
    }
    void printType(int x) {
        System.out.println(x + " is an int");
    }
    void printType(float x) {
        System.out.println(x + " is an float");
    }
    void printType(double x) {
        System.out.println(x + " is an double");
    }
    void printType(char x) {
        System.out.println(x + " is an char");
    }
}

then:

Typetester t = new Typetester();
t.printType( yourVariable );

You can bypass the same-origin-policy by either creating a browser extension or even saving the file as .hta in Windows (HTML Application).

If you are using Header with GridLayoutManager use this code written in kotlin for spacing between the grids :

inner class SpacesItemDecoration(itemSpace: Int) : RecyclerView.ItemDecoration() {
    var space: Int = itemSpace

    override fun getItemOffsets(outRect: Rect?, view: View?, parent: RecyclerView?, state: RecyclerView.State?) {
        super.getItemOffsets(outRect, view, parent, state)
        val position = parent!!.getChildAdapterPosition(view)
        val viewType = parent.adapter.getItemViewType(position)
       //check to not to set any margin to header item 
        if (viewType == GridViewAdapter.TYPE_HEADER) {
            outRect!!.top = 0
            outRect.left = 0
            outRect.right = 0
            outRect.bottom = 0
        } else {
            outRect!!.left = space
            outRect.right = space
            outRect.bottom = space

            if (parent.getChildLayoutPosition(view) == 0) {
                outRect.top = space
            } else {
                outRect.top = 0
            }
        }
    }
    }

And pass ItemDecoration to recyclerview as

mIssueGridView.addItemDecoration(SpacesItemDecoration(10))

You don't need to - if the favicon is place in the root at favicon.ico, browsers will automatically pick it up.

If you don't see it working, clear your cache etc, it does work without the markup. You only need to use the code if you want to call it something else, or put it on a CDN for instance.

The easiest lib I have used is Paolo Gios's library. It's basically

Create GiosPDFDocument object
Create TextArea object
Add text, images, etc to TextArea object
Add TextArea object to PDFDocument object
Write to stream

This is a great tutorial to get you started.

I used a temp table and finally got this to work. Here is the logic that is used once you create the temp table:

UPDATE your_table, temp
SET your_table.value = temp.value
WHERE your_table.id = temp.id

Instead of navigating through the commits, you can also hit the y key (Github Help, Keyboard Shortcuts) to get the "permalink" for the current revision / commit.
This will change the URL from https://github.com/<user>/<repository> (master / HEAD) to https://github.com/<user>/<repository>/tree/<commit id>.

In order to download the specific commit, you'll need to reload the page from that URL, so the Clone or Download button will point to the "snapshot" https://github.com/<user>/<repository>/archive/<commit id>.zip instead of the latest https://github.com/<user>/<repository>/archive/master.zip.

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

readline is specifically designed to work with terminal (that is process.stdin.isTTY === true). There are a lot of modules which provide split functionality for generic streams, like split. It makes things super-easy:

process.stdin.pipe(require('split')()).on('data', processLine)

function processLine (line) {
  console.log(line + '!')
}

I'm using:

SELECT CAST(SYSTIMESTAMP AT TIME ZONE 'UTC' AS DATE) FROM DUAL;

It's working fine for me.

Make sure you wrap your "row" inside the class "container" . Also add reference to bootstrap in your html.
Something like this should work:
<html lang="en">

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
</head>
 <body>
     <p>lets learn!</p>
  <div class="container">
          <div class="row">
              <div class="col-lg-6" style="background-color: red;">
                  ONE
              </div>
              <div class="col-lg-2" style="background-color: blue;">
                  TWO
              </div>
              <div class="col-lg-4" style="background-color: green;">

           </div>
          </div>

BigInteger.toString(radix) will do what you want. Just pass in a radix of 2.

static String hexToBin(String s) {
  return new BigInteger(s, 16).toString(2);
}

Use count():

sc=scorm.objects.filter(Header__id=qp.id)

if sc.count() > 0:
   ...

The advantage over e.g. len() is, that the QuerySet is not yet evaluated:

count() performs a SELECT COUNT(*) behind the scenes, so you should always use count() rather than loading all of the record into Python objects and calling len() on the result.

Having this in mind, When QuerySets are evaluated can be worth reading.

If you use get(), e.g. scorm.objects.get(pk=someid), and the object does not exists, an ObjectDoesNotExist exception is raised:

from django.core.exceptions import ObjectDoesNotExist
try:
    sc = scorm.objects.get(pk=someid)
except ObjectDoesNotExist:
    print ...

Update: it's also possible to use exists():

if scorm.objects.filter(Header__id=qp.id).exists():
    ....

Returns True if the QuerySet contains any results, and False if not. This tries to perform the query in the simplest and fastest way possible, but it does execute nearly the same query as a normal QuerySet query.

compile fileTree(dir: '//you libraries location//', include: ['android-ColorPickerPreference'])

Use above line in your app's gradle file instead of

compile project(':android-ColorPickerPreference')

Hope it helps

You cannot in pure CSS. Having an image covering the whole page behind all other components is probably your best bet (looks like that's the solution given above). Anyway, chances are it will look awful anyway. I would try either an image big enough to cover most screen resolutions (say up to 1600x1200, above it is scarcer), to limit the width of the page, or just to use an image that tile.

I found this on the Bootstrap website, but it really isn't a Bootstrap class, it's just HTML.

<strong>rendered as bold text</strong>

In the context of the asked question and in reply to the comment by @sereja1c, creating SERIAL implicitly creates sequences, so for the above example-

CREATE TABLE foo (id SERIAL,bar varchar);

CREATE TABLE would implicitly create sequence foo_id_seq for serial column foo.id. Hence, SERIAL [4 Bytes] is good for its ease of use unless you need a specific datatype for your id.

Replace all the spaces in the String with empty character.

String lineWithoutSpaces = line.replaceAll("\\s+","");

If you are using impdp command example from @sathyajith-bhat response:

impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;

you will need to use mandatory parameter directory and create and grant it as:

CREATE OR REPLACE DIRECTORY DMP_DIR AS 'c:\Users\USER\Downloads';
GRANT READ, WRITE ON DIRECTORY DMP_DIR TO {USER};

or use one of defined:

My ORACLE Express 11g R2 has default named DATA_PUMP_DIR (located at {inst_dir}\app\oracle/admin/xe/dpdump/) you sill need to grant it for your user.

The accepted answer here isn't working with any Markdown editor available in the apps I have used till date like Ghost, Stackedit.io or even in the StackOverflow editor. I found a workaround here in the StackEdit.io issue tracker.

The solution is to directly use HTML syntax, and it works perfectly:

<img src="http://....jpg" width="200" height="200" />

I want to cover the whole web page before prompting a modal popup. I tried many methods using CSS and Javascript but none of them help until I figure out the following solution. It works for me, I hope it helps you too.

If anyone wants to enable dark mode, you may follow the below steps

• Open your Notepad++, and select “Settings” on the menu bar, and choose “Style configurator”.
• Select theme “Obsidian” (you can choose other dark themes)
• Click on Save&Colse

I used mkdir -p /root/.android && touch /root/.android/repositories.cfg to make it works

format is definitely the most elegant way, but afaik you can't use that with python's logging module, so here's how you can do it using the % formatting:

formatter = logging.Formatter(
    fmt='%(asctime)s | %(name)-20s | %(levelname)-10s | %(message)s',
)

Here, the - indicates left-alignment, and the number before s indicates the fixed width.

Some sample output:

More info at the docs here: https://docs.python.org/2/library/stdtypes.html#string-formatting-operations

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview

Just for reference I found this worked for me.

diskutil unmount /path/to/directory/

When I used the umount command I got an error that recommended this diskutil command.

I use this piece of code for age calculation ,Hope this helps ..no libraries used

private static DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());

public static int calculateAge(String date) {

    int age = 0;
    try {
        Date date1 = dateFormat.parse(date);
        Calendar now = Calendar.getInstance();
        Calendar dob = Calendar.getInstance();
        dob.setTime(date1);
        if (dob.after(now)) {
            throw new IllegalArgumentException("Can't be born in the future");
        }
        int year1 = now.get(Calendar.YEAR);
        int year2 = dob.get(Calendar.YEAR);
        age = year1 - year2;
        int month1 = now.get(Calendar.MONTH);
        int month2 = dob.get(Calendar.MONTH);
        if (month2 > month1) {
            age--;
        } else if (month1 == month2) {
            int day1 = now.get(Calendar.DAY_OF_MONTH);
            int day2 = dob.get(Calendar.DAY_OF_MONTH);
            if (day2 > day1) {
                age--;
            }
        }
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return age ;
}

date = new DateTime(date.year, date.month, date.day, HH, MM, SS);

I can offer two options

1. Direct copy

Based on your description I'm guessing you are doing something like

Set wb2 = Application.Workbooks.Open("YourFile.xls")
wb2.Sheets("YourSheet").[<YourRange>].Copy
ThisWorkbook.Sheets("SomeSheet").Paste
wb2.close

If this is the case, you don't need to copy via the clipboard. This method copies from source to destination directly. No data in clipboard = no prompt

Set wb2 = Application.Workbooks.Open("YourFile.xls")
wb2.Sheets("YourSheet").[<YourRange>].Copy ThisWorkbook.Sheets("SomeSheet").Cells(<YourCell")
wb2.close

2. Suppress prompt

You can prevent all alert pop-ups by setting

Application.DisplayAlerts = False

[Edit]

3. To copy values only: don't use copy/paste at all

Dim rSrc As Range
Dim rDst As Range
Set rSrc = wb2.Sheets("YourSheet").Range("YourRange")
Set rDst = ThisWorkbook.Sheets("SomeSheet").Cells("YourCell").Resize(rSrc.Rows.Count, rSrc.Columns.Count)
rDst = rSrc.Value

Solution for EF Core

public class User
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Passport { get; set; }
}

public class ApplicationContext : DbContext
{
    public DbSet<User> Users { get; set; }
    public ApplicationContext()
    {
        Database.EnsureCreated();
    }
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer(@"Server=(localdb)\mssqllocaldb;Database=efbasicsappdb;Trusted_Connection=True;");
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<User>().HasAlternateKey(u => u.Passport);
        //or: modelBuilder.Entity<User>().HasAlternateKey(u => new { u.Passport, u.Name})
    }
}

DB table will look like this:

CREATE TABLE [dbo].[Users] (
    [Id]       INT            IDENTITY (1, 1) NOT NULL,
    [Name]     NVARCHAR (MAX) NULL,
    [Passport] NVARCHAR (450) NOT NULL,
    CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED ([Id] ASC),
    CONSTRAINT [AK_Users_Passport] UNIQUE NONCLUSTERED ([Passport] ASC)
);

Ref to EF Core docs

You can use this code:

AppDomain.CurrentDomain.BaseDirectory

Other type of format :

$headers[] = 'Accept: application/json';
$headers[] = 'Content-Type: application/json';
$headers[] = 'Content-length: 0';

curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);

To copy a folder file from local to hdfs, you can the below command

hadoop fs -put /path/localpath  /path/hdfspath

or

hadoop fs -copyFromLocal /path/localpath  /path/hdfspath

I used a third party library called use-force-update to force render my react functional components. Worked like charm. Just use import the package in your project and use like this.

import useForceUpdate from 'use-force-update';

const MyButton = () => {

  const forceUpdate = useForceUpdate();

  const handleClick = () => {
    alert('I will re-render now.');
    forceUpdate();
  };

  return <button onClick={handleClick} />;
};

Try using an empty collapse argument within the paste function:

paste(sdata, collapse = '')

In CLI

$ webpack --version
    
webpack-cli 4.1.0
    
webpack 5.3.2

In Code (node runtime)

In Plugin

compiler.webpack.version // 5.3.2

This is probably slower than what you want, but you can do:

>>> tostring = vectorize(lambda x: str(x))
>>> numpy.where(tostring(phis).astype('float64') != phis)
(array([], dtype=int64),)

It looks like it rounds off the values when it converts to str from float64, but this way you can customize the conversion however you like.

You can achieve this with: EventTarget.dispatchEvent(event) and by passing in a new KeyboardEvent as the event.

For example: element.dispatchEvent(new KeyboardEvent('keypress', {'key': 'a'}))

Working example:

// get the element in question_x000D_
const input = document.getElementsByTagName("input")[0];_x000D_
_x000D_
// focus on the input element_x000D_
input.focus();_x000D_
_x000D_
// add event listeners to the input element_x000D_
input.addEventListener('keypress', (event) => {_x000D_
  console.log("You have pressed key: ", event.key);_x000D_
});_x000D_
_x000D_
input.addEventListener('keydown', (event) => {_x000D_
  console.log(`key: ${event.key} has been pressed down`);_x000D_
});_x000D_
_x000D_
input.addEventListener('keyup', (event) => {_x000D_
  console.log(`key: ${event.key} has been released`);_x000D_
});_x000D_
_x000D_
// dispatch keyboard events_x000D_
input.dispatchEvent(new KeyboardEvent('keypress',  {'key':'h'}));_x000D_
input.dispatchEvent(new KeyboardEvent('keydown',  {'key':'e'}));_x000D_
input.dispatchEvent(new KeyboardEvent('keyup', {'key':'y'}));

<input type="text" placeholder="foo" />

This CSS might work for <input type="button" ..:

white-space: normal

That isn't part of the purview of CSS. colspan describes the structure of the page's content, or gives some meaning to the data in the table, which is HTML's job.

Ctrl+D Difference for Windows and Linux

It turns out that as of Python 3.6, the Python interpreter handles Ctrl+C differently for Linux and Windows. For Linux, Ctrl+C would work mostly as expected however on Windows Ctrl+C mostly doesn't work especially if Python is running blocking call such as thread.join or waiting on web response. It does work for time.sleep, however. Here's the nice explanation of what is going on in Python interpreter. Note that Ctrl+C generates SIGINT.

Solution 1: Use Ctrl+Break or Equivalent

Use below keyboard shortcuts in terminal/console window which will generate SIGBREAK at lower level in OS and terminate the Python interpreter.

Mac OS and Linux

Ctrl+Shift+</kbd> or Ctrl+</kbd>

Windows:

• General: Ctrl+Break
• Dell: Ctrl+Fn+F6 or Ctrl+Fn+S
• Lenovo: Ctrl+Fn+F11 or Ctrl+Fn+B
• HP: Ctrl+Fn+Shift
• Samsung: Fn+Esc

Solution 2: Use Windows API

Below are handy functions which will detect Windows and install custom handler for Ctrl+C in console:

#win_ctrl_c.py

import sys

def handler(a,b=None):
    sys.exit(1)
def install_handler():
    if sys.platform == "win32":
        import win32api
        win32api.SetConsoleCtrlHandler(handler, True)

You can use above like this:

import threading
import time
import win_ctrl_c

# do something that will block
def work():
    time.sleep(10000)        
t = threading.Thread(target=work)
t.daemon = True
t.start()

#install handler
install_handler()

# now block
t.join()

#Ctrl+C works now!

Solution 3: Polling method

I don't prefer or recommend this method because it unnecessarily consumes processor and power negatively impacting the performance.

    import threading
    import time

    def work():
        time.sleep(10000)        
    t = threading.Thread(target=work)
    t.daemon = True
    t.start()
    while(True):
        t.join(0.1) #100ms ~ typical human response
    # you will get KeyboardIntrupt exception

I just solved this type of problem. I was trying to increase

font-size to h4 size. I do not want to use h4 tag. I added my css after bootstrap.css it didn't work. The easiest way is this: On the HTML doc, type

<p class="h4">

You do not need to add anything to your css sheet. It works fine Question is suppose I want a size between h4 and h5? Answer why? Is this the only way to please your viewers? I will prefer this method to tampering with standard docs like bootstrap.

If you have supporting indexes, and relatively high counts, something like this may be considerably faster than the solutions suggested:

SELECT name, MAX(Rcount) + MAX(Acount) AS TotalCount
FROM (
  SELECT name, COUNT(*) AS Rcount, 0 AS Acount
  FROM Results GROUP BY name
  UNION ALL
  SELECT name, 0, count(*)
  FROM Archive_Results
  GROUP BY name
) AS Both
GROUP BY name
ORDER BY name;

Your problem is that all chapters, whether they're in the appendix or not, default to starting on an odd-numbered page when you're in two-sided layout mode. A few possible solutions:

The simplest solution is to use the openany option to your document class, which makes chapters start on the next page, irrespective of whether it's an odd or even numbered page. This is supported in the standard book documentclass, eg \documentclass[openany]{book}. (memoir also supports using this as a declaration \openany which can be used in the middle of a document to change the behavior for subsequent pages.)

Another option is to try the \let\cleardoublepage\clearpage command before your appendices to avoid the behavior.

Or, if you don't care using a two-sided layout, using the option oneside to your documentclass (eg \documentclass[oneside]{book}) will switch to using a one-sided layout.

Much easier way: use template literals.

var variable = 'foo'
var expression = `.*${variable}.*`
var re = new RegExp(expression, 'g')
re.test('fdjklsffoodjkslfd') // true
re.test('fdjklsfdjkslfd') // false

hey guys i think what you are looking for is this one using select command. With this you can specify a RANGE GREATER THAN(>) OR LESSER THAN(<) IN MySQL WITH THIS:::::

select* from <**TABLE NAME**> where year(**COLUMN NAME**) > **DATE** OR YEAR(COLUMN NAME )< **DATE**;

FOR EXAMPLE:

select name, BIRTH from pet1 where year(birth)> 1996 OR YEAR(BIRTH)< 1989;
+----------+------------+
| name     | BIRTH      |
+----------+------------+
| bowser   | 1979-09-11 |
| chirpy   | 1998-09-11 |
| whistler | 1999-09-09 |
+----------+------------+

FOR SIMPLE RANGE LIKE USE ONLY GREATER THAN / LESSER THAN

mysql> select COLUMN NAME from <TABLE NAME> where year(COLUMN NAME)> 1996;

FOR EXAMPLE mysql>

select name from pet1 where year(birth)> 1996 OR YEAR(BIRTH)< 1989;
+----------+
| name     |
+----------+
| bowser   |
| chirpy   |
| whistler |
+----------+

As of pandas 1.0.0, you no longer need to use numpy to create null values in your dataframe. Instead you can just use pandas.NA (which is of type pandas._libs.missing.NAType), so it will be treated as null within the dataframe but will not be null outside dataframe context.

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

Sorry for the necro on this post, but I feel compelled to weigh in on a couple of things that do not seem to have been touched on.

First a foremost - when we find ourselves needing access to private members on a class during unit testing, it is generally a big, fat red flag that we've goofed in our strategic or tactical approach and have inadvertently violated the single responsibility principal by pushing behavior where it does not belong. Feeling the need to access methods that are really nothing more than an isolated subroutine of a construction procedure is one of the most common occurrences of this; however, it's kind of like your boss expecting you to show up for work ready-to-go and also having some perverse need to know what morning routine you went through to get you into that state...

The other most common instance of this happening is when you find yourself trying to test the proverbial "god class." It is a special kind of problem in and of itself, but suffers from the same basic issue with needing to know intimate details of a procedure - but that's getting off topic.

In this specific example, we've effectively assigned the responsibility of fully initializing the Bar object to the FooBar class's constructor. In object oriented programming, one of the core tenents is that the constructor is "sacred" and should be guarded against invalid data that would invalidate its' own internal state and leave it primed to fail somewhere else downstream (in what could be a very deep pipeline.)

We've failed to do that here by allowing the FooBar object to accept a Bar that is not ready at the time that the FooBar is constructed, and have compensated by sort-of "hacking" the FooBar object to take matters into its' own hands.

This is the result of a failure to adhere to another tenent of object oriented programming (in the case of Bar,) which is that an object's state should be fully initialized and ready to handle any incoming calls to its' public members immediately after creation. Now, this does not mean immediately after the constructor is called in all instances. When you have an object that has many complex construction scenarios, then it is better to expose setters to its optional members to an object that is implemented in accordance with a creation design-pattern (Factory, Builder, etc...) In any of the latter cases, you would be pushing the initialization of the target object off into another object graph whose sole purpose is directing traffic to get you to a point where you have a valid instance of that which you are requesting - and the product should not be considered "ready" until after this creation object has served it up.

In your example, the Bar's "status" property does not seem to be in a valid state in which a FooBar can accept it - so the FooBar does something to it to correct that issue.

The second issue I am seeing is that it appears that you are trying to test your code rather than practice test-driven development. This is definitely my own opinion at this point in time; but, this type of testing is really an anti-pattern. What you end up doing is falling into the trap of realizing that you have core design problems that prevent your code from being testable after the fact, rather than writing the tests you need and subsequently programming to the tests. Either way you come at the problem, you should still end up with the same number of tests and lines of code had you truly achieved a SOLID implementation. So - why try and reverse engineer your way into testable code when you can just address the matter at the onset of your development efforts?

Had you done that, then you would have realized much earlier on that you were going to have to write some rather icky code in order to test against your design and would have had the opportunity early on to realign your approach by shifting behavior to implementations that are easily testable.

I like what Franz said, because is what I'm using :P

var date_ini = new Date($('#id_date_ini').val()).getTime();
var date_end = new Date($('#id_date_end').val()).getTime();
if (isNaN(date_ini)) {
// error date_ini;
}
if (isNaN(date_end)) {
// error date_end;
}
if (date_ini > date_end) {
// do something;
}

you can also do this

$model->hidden1 = 'your value';// better put it on controller
$form->field($model, 'hidden1')->hiddenInput()->label(false);

this is a better option if you set value on controller

$model = new SomeModelName();

if ($model->load(Yii::$app->request->post()) && $model->save()) {
    return $this->redirect(['view', 'id' => $model->group_id]);
 } else {
    $model->hidden1 = 'your value';
    return $this->render('create', [
        'model' => $model,
    ]);
 }

My solution is based on XML configuration using spring-boot-starter-log4j. The example is a basic example using spring-boot-starter and the two Loggers writes into different log files.

This is an answer for those not familiar with Vim and coming from other text editors (in my case Sublime Text).

I read through all these answers and it still wasn't clear. If you read through them enough things begin to make sense, but it took me hours of going back and forth between questions.

The first thing is, as others have explained:

Tab Pages, sound a lot like tabs, they act like tabs and look a lot like tabs in most other GUI editors, but they're not. I think it's an a bad mental model that was built on in Vim, which unfortunately clouds the extra power that you have within a tab page.

The first description that I understood was from @crenate's answer is that they are the equivalent to multiple desktops. When seen in that regard you'd only ever have a couple of desktops open but have lots of GUI windows open within each one.

I would say they are similar to in other editors/browsers:

1. Tab groupings
2. Sublime Text workspaces (i.e. a list of the open files that you have in a project)

When you see them like that you realise the power of them that you can easily group sets of files (buffers) together e.g. your CSS files, your HTML files and your JS files in different tab pages. Which is actually pretty awesome.

Other descriptions that I find confusing

Viewport

This makes no sense to me. A viewport which although it does have a defined dictionary term, I've only heard referring to Vim windows in the :help window doc. Viewport is not a term I've ever heard with regards to editors like Sublime Text, Visual Studio, Atom, Notepad++. In fact I'd never heard about it for Vim until I started to try using tab pages.

If you view tab pages like multiple desktops, then referring to a desktop as a single window seems odd.

Workspaces

This possibly makes more sense, the dictionary definition is:

A memory storage facility for temporary use.

So it's like a place where you store a group of buffers.

I didn't initially sound like Sublime Text's concept of a workspace which is a list of all the files that you have open in your project:

the sublime-workspace file, which contains user specific data, such as the open files and the modifications to each.

However thinking about it more, this does actually agree. If you regard a Vim tab page like a Sublime Text project, then it would seem odd to have just one file open in each project and keep switching between projects. Hence why using a tab page to have open only one file is odd.

Collection of windows

The :help window refers to tab pages this way. Plus numerous other answers use the same concept. However until you get your head around what a vim window is, then that's not much use, like building a castle on sand.

As I referred to above, a vim window is the same as a viewport and quiet excellently explained in this linux.com article:

A really useful feature in Vim is the ability to split the viewable area between one or more files, or just to split the window to view two bits of the same file more easily. The Vim documentation refers to this as a viewport or window, interchangeably.

You may already be familiar with this feature if you've ever used Vim's help feature by using :help topic or pressing the F1 key. When you enter help, Vim splits the viewport and opens the help documentation in the top viewport, leaving your document open in the bottom viewport.

I find it odd that a tab page is referred to as a collection of windows instead of a collection of buffers. But I guess you can have two separate tab pages open each with multiple windows all pointing at the same buffer, at least that's what I understand so far.

Under Tools -> Android Device Monitor

And under File Explorer. Search for the apps. And the file is under data/data.

I'd use bootstrap and set the html as:

<div class="row">
    <div class="col-md-4">
        <img src="img/logo.png" alt="logo" />
    </div>
    <div class="col-md-8">
        <h1>My website name</h1>
    </div>
</div>

The script tag to the api has changed recently. Use something like this to query the Geocoding API and get the JSON object back

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/geocode/json?address=THE_ADDRESS_YOU_WANT_TO_GEOCODE&key=YOUR_API_KEY"></script>

The address could be something like

1600+Amphitheatre+Parkway,+Mountain+View,+CA (URI Encoded; you should Google it. Very useful)

or simply

1600 Amphitheatre Parkway, Mountain View, CA

By entering this address https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY inside the browser, along with my API Key, I get back a JSON object which contains the Latitude & Longitude for the city of Moutain view, CA.

Web Frameworks such like AngularJS allow us to perform these queries with ease.

Here are the steps I follow to delete a topic named MyTopic:

1. Describe the topic, and take not of the broker ids
2. Stop the Apache Kafka daemon for each broker ID listed.
3. Connect to each broker, and delete the topic data folder, e.g. rm -rf /tmp/kafka-logs/MyTopic-0. Repeat for other partitions, and all replicas
4. Delete the topic metadata: zkCli.sh then rmr /brokers/MyTopic
5. Start the Apache Kafka daemon for each stopped machine

If you miss you step 3, then Apache Kafka will continue to report the topic as present (for example when if you run kafka-list-topic.sh).

Tested with Apache Kafka 0.8.0.

You should do something like this to help you debug

$sql = "insert into blah values ('$myVar')";
echo $sql;

You will probably find that the single quote is escaped with a backslash in the working query. This might have been done automatically by PHP via the magic_quotes_gpc setting, or maybe you did it yourself in some other part of the code (addslashes and stripslashes might be functions to look for).

See Magic Quotes

Yes, you need the full path.

log = open(os.path.join(root, f), 'r')

Is the quick fix. As the comment pointed out, os.walk decends into subdirs so you do need to use the current directory root rather than indir as the base for the path join.

Like you I didn't find it came naturally. I normally still have to remind myself that

• the length of the returned string is

  lastIndex - firstIndex

• that you can use the length of the string as the lastIndex even though there is no character there and trying to reference it would throw an Exception

so

"University".substring(6, 10)

returns the 4-character string "sity" even though there is no character at position 10.

Just to include one more alternative, you could also use this:

find "/starting/path" -type f -regextype posix-extended -regex "^.*\.(php|html|js)$" -exec grep -EH '(document\.cookie|setcookie)' {} \;

Where:

• -regextype posix-extended tells find what kind of regex to expect
• -regex "^.*\.(php|html|js)$" tells find the regex itself filenames must match

• -exec grep -EH '(document\.cookie|setcookie)' {} \; tells find to run the command (with its options and arguments) specified between the -exec option and the \; for each file it finds, where {} represents where the file path goes in this command.

  while

  • E option tells grep to use extended regex (to support the parentheses) and...
  • H option tells grep to print file paths before the matches.

And, given this, if you only want file paths, you may use:

find "/starting/path" -type f -regextype posix-extended -regex "^.*\.(php|html|js)$" -exec grep -EH '(document\.cookie|setcookie)' {} \; | sed -r 's/(^.*):.*$/\1/' | sort -u

Where

• | [pipe] send the output of find to the next command after this (which is sed, then sort)
• r option tells sed to use extended regex.
• s/HI/BYE/ tells sed to replace every First occurrence (per line) of "HI" with "BYE" and...
• s/(^.*):.*$/\1/ tells it to replace the regex (^.*):.*$ (meaning a group [stuff enclosed by ()] including everything [.* = one or more of any-character] from the beginning of the line [^] till' the first ':' followed by anything till' the end of line [$]) by the first group [\1] of the replaced regex.
• u tells sort to remove duplicate entries (take sort -u as optional).

...FAR from being the most elegant way. As I said, my intention is to increase the range of possibilities (and also to give more complete explanations on some tools you could use).

There are 3 ways I can think of:

The way that is easiest to explain is

:%s/phrase to delete//gc

but you can also (personally I use this second one more often) do a regular search for the phrase to delete

/phrase to delete

Vim will take you to the beginning of the next occurrence of the phrase.

Go into insert mode (hit i) and use the Delete key to remove the phrase.

Hit escape when you have deleted all of the phrase.

Now that you have done this one time, you can hit n to go to the next occurrence of the phrase and then hit the dot/period "." key to perform the delete action you just performed

Continue hitting n and dot until you are done.

Lastly you can do a search for the phrase to delete (like in second method) but this time, instead of going into insert mode, you

Count the number of characters you want to delete

Type that number in (with number keys)

Hit the x key - characters should get deleted

Continue through with n and dot like in the second method.

PS - And if you didn't know already you can do a capital n to move backwards through the search matches.

You may be interested by the pack_forget and grid_forget methods of a widget. In the following example, the button disappear when clicked

from Tkinter import *

def hide_me(event):
    event.widget.pack_forget()

root = Tk()
btn=Button(root, text="Click")
btn.bind('<Button-1>', hide_me)
btn.pack()
btn2=Button(root, text="Click too")
btn2.bind('<Button-1>', hide_me)
btn2.pack()
root.mainloop()

This is what I did:

Very simply put:

=IF(C7>100,"Profit",IF(C7=100,"Quota Met","Loss"))

The first IF Statement, if true will input Profit, and if false will lead on to the next IF statement and so forth :)

I only have basic formula knowledge but it's working so I will accept I am right!

If you are using Query builder then you may use a blow

DB::table(Newsletter Subscription)
->select('*')
->whereIn('id', $send_users_list)
->get()

If you are working with Eloquent then you can use as below

$sendUsersList = Newsletter Subscription:: select ('*')
                ->whereIn('id', $send_users_list)
                ->get();

Atomic reference should be used in a setting where you need to do simple atomic (i.e. thread-safe, non-trivial) operations on a reference, for which monitor-based synchronization is not appropriate. Suppose you want to check to see if a specific field only if the state of the object remains as you last checked:

AtomicReference<Object> cache = new AtomicReference<Object>();

Object cachedValue = new Object();
cache.set(cachedValue);

//... time passes ...
Object cachedValueToUpdate = cache.get();
//... do some work to transform cachedValueToUpdate into a new version
Object newValue = someFunctionOfOld(cachedValueToUpdate);
boolean success = cache.compareAndSet(cachedValue,cachedValueToUpdate);

Because of the atomic reference semantics, you can do this even if the cache object is shared amongst threads, without using synchronized. In general, you're better off using synchronizers or the java.util.concurrent framework rather than bare Atomic* unless you know what you're doing.

Two excellent dead-tree references which will introduce you to this topic:

• Herlihy's excellent Art of Multiprocessor Programming
• Java Concurrency in Practice

Note that (I don't know if this has always been true) reference assignment (i.e. =) is itself atomic (updating primitive 64-bit types like long or double may not be atomic; but updating a reference is always atomic, even if it's 64 bit) without explicitly using an Atomic*.
See the Java Language Specification 3ed, Section 17.7.

The answer to your question is that the newer SQLite 3 has improved performance, use that.

This answer Why is SQLAlchemy insert with sqlite 25 times slower than using sqlite3 directly? by SqlAlchemy Orm Author has 100k inserts in 0.5 sec, and I have seen similar results with python-sqlite and SqlAlchemy. Which leads me to believe that performance has improved with SQLite 3.

Is your problem similar to this:

l = [[0]] * 4
l[0][0] += 1
print l # prints "[[1], [1], [1], [1]]"

If so, you simply need to copy the objects when you store them:

import copy
l = [copy.copy(x) for x in [[0]] * 4]
l[0][0] += 1
print l # prints "[[1], [0], [0], [0]]"

The objects in question should implement a __copy__ method to copy objects. See the documentation for copy. You may also be interested in copy.deepcopy, which is there as well.

EDIT: Here's the problem:

arrayList = []
for x in allValues:
    result = model(x)
    arrayList.append(wM) # appends the wM object to the list
    wM.reset()           # clears  the wM object

You need to append a copy:

import copy
arrayList = []
for x in allValues:
    result = model(x)
    arrayList.append(copy.copy(wM)) # appends a copy to the list
    wM.reset()                      # clears the wM object

But I'm still confused as to where wM is coming from. Won't you just be copying the same wM object over and over, except clearing it after the first time so all the rest will be empty? Or does model() modify the wM (which sounds like a terrible design flaw to me)? And why are you throwing away result?

this datepicker is an excellent solution. datepickers are a must if you want to avoid code injection.

From the documentation:

We can add to a list in many ways:

assert [1,2] + 3 + [4,5] + 6 == [1, 2, 3, 4, 5, 6]
assert [1,2].plus(3).plus([4,5]).plus(6) == [1, 2, 3, 4, 5, 6]
    //equivalent method for +
def a= [1,2,3]; a += 4; a += [5,6]; assert a == [1,2,3,4,5,6]
assert [1, *[222, 333], 456] == [1, 222, 333, 456]
assert [ *[1,2,3] ] == [1,2,3]
assert [ 1, [2,3,[4,5],6], 7, [8,9] ].flatten() == [1, 2, 3, 4, 5, 6, 7, 8, 9]

def list= [1,2]
list.add(3) //alternative method name
list.addAll([5,4]) //alternative method name
assert list == [1,2,3,5,4]

list= [1,2]
list.add(1,3) //add 3 just before index 1
assert list == [1,3,2]
list.addAll(2,[5,4]) //add [5,4] just before index 2
assert list == [1,3,5,4,2]

list = ['a', 'b', 'z', 'e', 'u', 'v', 'g']
list[8] = 'x'
assert list == ['a', 'b', 'z', 'e', 'u', 'v', 'g', null, 'x']

You can also do:

def myNewList = myList << "fifth"

Q: So my question is this - if throwing from a destructor results in undefined behavior, how do you handle errors that occur during a destructor?

A: There are several options:

1. Let the exceptions flow out of your destructor, regardless of what's going on elsewhere. And in doing so be aware (or even fearful) that std::terminate may follow.

2. Never let exception flow out of your destructor. May be write to a log, some big red bad text if you can.

3. my fave : If std::uncaught_exception returns false, let you exceptions flow out. If it returns true, then fall back to the logging approach.

But is it good to throw in d'tors?

I agree with most of the above that throwing is best avoided in destructor, where it can be. But sometimes you're best off accepting it can happen, and handle it well. I'd choose 3 above.

There are a few odd cases where its actually a great idea to throw from a destructor. Like the "must check" error code. This is a value type which is returned from a function. If the caller reads/checks the contained error code, the returned value destructs silently. But, if the returned error code has not been read by the time the return values goes out of scope, it will throw some exception, from its destructor.

Dir

Use the dir command. Type in dir /? for help and options.

dir /a:d /b

Redirect

Then use a redirect to save the list to a file.

> list.txt

Together

dir /a:d /b > list.txt

This will output just the names of the directories. if you want the full path of the directories use this below.

Full Path

for /f "delims=" %%D in ('dir /a:d /b') do echo %%~fD

Alternative

other method just using the for command. See for /? for help and options. This can output just the name %%~nxD or the full path %%~fD

for /d %%D in (*) do echo %%~fD

Notes

To use these commands directly on the command line, change the double percent signs to single percent signs. %% to %

To redirect the for methods, just add the redirect after the echo statements. Use the double arrow >> redirect here to append to the file, else only the last statement will be written to the file due to overwriting all the others.

... echo %%~fD>> list.txt

Here is my workaround,
In your example you can add a third element with "same styles" of .one & .two elements, but without the absolute position and with hidden visibility:

HTML

<article>
   <div class="one"></div>
   <div class="two"></div>
   <div class="three"></div>
</article>

CSS

.three{
    height: 30px;
    z-index: -1;
    visibility: hidden;
}

public static string ComputeSHA256Hash(string text)
{
    using (var sha256 = new SHA256Managed())
    {
        return BitConverter.ToString(sha256.ComputeHash(Encoding.UTF8.GetBytes(text))).Replace("-", "");
    }                
}

The reason why you get different results is because you don't use the same string encoding. The link you put for the on-line web site that computes SHA256 uses UTF8 Encoding, while in your example you used Unicode Encoding. They are two different encodings, so you don't get the same result. With the example above you get the same SHA256 hash of the linked web site. You need to use the same encoding also in PHP.

In windows:

java -cp C:/.../jardir1/*;C:/.../jardir2/* class_with_main_method

make sure that the class with the main function is in one of the included jars

I usually just remove all quotes from my variables with:

set var=%var:"=%

And then apply them again wherever I need them e.g.:

echo "%var%"

Window ? Preferences ? General ? Network Connections then under "Proxy ByPass" click "Add Host" and enter the link from which you will be getting your third-party plugin; that's it bingo, now it should get the plugin no problem.

I've been troubled with this problem in web printing and solved. Verified result.

a {
    text-decoration: none !important;

It works!.

I use this

<staticContent>
<clientCache cacheControlCustom="public" cacheControlMode="UseMaxAge" cacheControlMaxAge="500.00:00:00" />
</staticContent>

to cache static content for 500 days with public cache-control header.

Or you can use regular expression to handle multiple items as the general case of this issue,

df['2nd'] = pd.to_numeric(df['2nd'].str.replace(r'[,.%]','')) 
df['CTR'] = pd.to_numeric(df['CTR'].str.replace(r'[^\d%]',''))

To align some elements (headerElement) in the center and the last element to the right (headerEnd).

.headerElement {
    margin-right: 5%;
    margin-left: 5%;
}
.headerEnd{
    margin-left: auto;
}

ES6 solution:

const timestamp = () => `[${new Date().toUTCString()}]`
const log = (...args) => console.log(timestamp(), ...args)

where timestamp() returns actually formatted timestamp and log add a timestamp and propagates all own arguments to console.log

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

Handle intent on startCommand of service by using.

 stopForeground(true)

This call will remove the service from foreground state, allowing it to be killed if more memory is needed. This does not stop the service from running. For that, you need to call stopSelf() or related methods.

Passing value true or false indicated if you want to remove the notification or not.

val ACTION_STOP_SERVICE = "stop_service"
val NOTIFICATION_ID_SERVICE = 1
...  
override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
    super.onStartCommand(intent, flags, startId)
    if (ACTION_STOP_SERVICE == intent.action) {
        stopForeground(true)
        stopSelf()
    } else {
        //Start your task

        //Send forground notification that a service will run in background.
        sendServiceNotification(this)
    }
    return Service.START_NOT_STICKY
}

Handle your task when on destroy is called by stopSelf().

override fun onDestroy() {
    super.onDestroy()
    //Stop whatever you started
}

Create a notification to keep the service running in foreground.

//This is from Util class so as not to cloud your service
fun sendServiceNotification(myService: Service) {
    val notificationTitle = "Service running"
    val notificationContent = "<My app> is using <service name> "
    val actionButtonText = "Stop"
    //Check android version and create channel for Android O and above
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        //You can do this on your own
        //createNotificationChannel(CHANNEL_ID_SERVICE)
    }
    //Build notification
    val notificationBuilder = NotificationCompat.Builder(applicationContext, CHANNEL_ID_SERVICE)
    notificationBuilder.setAutoCancel(true)
            .setDefaults(NotificationCompat.DEFAULT_ALL)
            .setWhen(System.currentTimeMillis())
            .setSmallIcon(R.drawable.ic_location)
            .setContentTitle(notificationTitle)
            .setContentText(notificationContent)
            .setVibrate(null)
    //Add stop button on notification
    val pStopSelf = createStopButtonIntent(myService)
    notificationBuilder.addAction(R.drawable.ic_location, actionButtonText, pStopSelf)
    //Build notification
    val notificationManagerCompact = NotificationManagerCompat.from(applicationContext)
    notificationManagerCompact.notify(NOTIFICATION_ID_SERVICE, notificationBuilder.build())
    val notification = notificationBuilder.build()
    //Start notification in foreground to let user know which service is running.
    myService.startForeground(NOTIFICATION_ID_SERVICE, notification)
    //Send notification
    notificationManagerCompact.notify(NOTIFICATION_ID_SERVICE, notification)
}

Give a stop button on notification to stop the service when user needs.

/**
 * Function to create stop button intent to stop the service.
 */
private fun createStopButtonIntent(myService: Service): PendingIntent? {
    val stopSelf = Intent(applicationContext, MyService::class.java)
    stopSelf.action = ACTION_STOP_SERVICE
    return PendingIntent.getService(myService, 0,
            stopSelf, PendingIntent.FLAG_CANCEL_CURRENT)
}

If you are doing these same assignments a lot in your program and want a shortcut, the most straightforward solution might be to just add a function

static inline void set_coordinates(
        GLfloat coordinates[static 8],
        GLfloat c0, GLfloat c1, GLfloat c2, GLfloat c3,
        GLfloat c4, GLfloat c5, GLfloat c6, GLfloat c7)
{
    coordinates[0] = c0;
    coordinates[1] = c1;
    coordinates[2] = c2;
    coordinates[3] = c3;
    coordinates[4] = c4;
    coordinates[5] = c5;
    coordinates[6] = c6;
    coordinates[7] = c7;
}

and then simply call

GLfloat coordinates[8];
// ...
set_coordinates(coordinates, 1.0f, 0.0f, 1.0f, 1.0f, 0.0f, 1.0f, 0.0f, 0.0f);

Make SymbolIndexer( const SymbolIndexer& ) private. If you're assigning to a reference, you're not copying.

I cannot believe nobody talked about using a relative parent element.

Code:

<div class="chart-container" style="position: relative; height:40vh; width:80vw">
  <canvas id="chart"></canvas>
</div>

I just discovered that the Mock library provides an assertRaisesWithMessage() method (in its unittest.TestCase subclass), which will check not only that the expected exception is raised, but also that it is raised with the expected message:

from testcase import TestCase

import mymod

class MyTestCase(TestCase):
    def test1(self):
        self.assertRaisesWithMessage(SomeCoolException,
                                     'expected message',
                                     mymod.myfunc)

Notification Vibrate

mBuilder.setVibrate(new long[] { 1000, 1000});

mBuilder.setSound(Settings.System.DEFAULT_NOTIFICATION_URI);

Keras now supports the use_bias=False option, so we can save some computation by writing like

model.add(Dense(64, use_bias=False))
model.add(BatchNormalization(axis=bn_axis))
model.add(Activation('tanh'))

or

model.add(Convolution2D(64, 3, 3, use_bias=False))
model.add(BatchNormalization(axis=bn_axis))
model.add(Activation('relu'))

Have a look at the Xtify platform. Looks like this is what they are doing,

Python 3.8 has the answer.

It's called assignment expressions. from the documentation:

# Loop over fixed length blocks
while (block := f.read(256)) != '':
    process(block)

In a web-based database application that uses a pop-up window to display print-outs of database data, this worked well enough for our needs (tested in Chrome 48):

<form method="post" 
      target="print_popup" 
      action="/myFormProcessorInNewWindow.aspx"
      onsubmit="window.open('about:blank','print_popup','width=1000,height=800');">

The trick is to match the target attribute on the <form> tag with the second argument in the window.open call in the onsubmit handler.

Adding "/usr/bin/git" >> Path to Git executable, didn't work for me. Then I deleted the contents of $JENKINS_HOME/fingerprints and restarted Jenkins. The problem goes away.

A war file is just a zip file with a specific directory structure. So you can use unzip or the jar tool for unzipping.

But you probably don't want to do that. If you add the war file into the webapps directory of Tomcat the Tomcat will take care of extracting/installing the war file.

To remove an entire folder from the repo (like Resharper files), do this:

git rm -r --cached folderName

I had committed some resharper files, and did not want those to persist for other project users.

By default new users will have permission to create tables. If you are planning to create a read-only user, this is probably not what you want.

To create a true read-only user with PostgreSQL 9.0+, run the following steps:

# This will prevent default users from creating tables
REVOKE CREATE ON SCHEMA public FROM public;

# If you want to grant a write user permission to create tables
# note that superusers will always be able to create tables anyway
GRANT CREATE ON SCHEMA public to writeuser;

# Now create the read-only user
CREATE ROLE readonlyuser WITH LOGIN ENCRYPTED PASSWORD 'strongpassword';
GRANT SELECT ON ALL TABLES IN SCHEMA public TO readonlyuser;

If your read-only user doesn't have permission to list tables (i.e. \d returns no results), it's probably because you don't have USAGE permissions for the schema. USAGE is a permission that allows users to actually use the permissions they have been assigned. What's the point of this? I'm not sure. To fix:

# You can either grant USAGE to everyone
GRANT USAGE ON SCHEMA public TO public;

# Or grant it just to your read only user
GRANT USAGE ON SCHEMA public TO readonlyuser;

Similar to Stone's answer, but for Windows/.NET developers:

If you have Visual Studio and ReSharper - An easy alternative for formatting Javascript is:

• Open the file with Visual Studio;
• Click on ReSharper > Tools > Cleanup Code (Ctrl+E, C);
• Select "Default: Reformat code", and click OK;
• Crack open a beer.

sudo gem install --no-user-install <gem-name>

will install your gem globally, i.e. it will be available to all user's contexts.

For the ones who like shorter and faster(not calling deg2rad()).

function circle_distance($lat1, $lon1, $lat2, $lon2) {
  $rad = M_PI / 180;
  return acos(sin($lat2*$rad) * sin($lat1*$rad) + cos($lat2*$rad) * cos($lat1*$rad) * cos($lon2*$rad - $lon1*$rad)) * 6371;// Kilometers
}

:last is not part of the css spec, this is jQuery specific.

you should be looking for last-child

var first = div.querySelector('[move_id]:first-child');
var last  = div.querySelector('[move_id]:last-child');

How about

mydatagrid.UpdateLayout();

This extension method will obtain a string representation of an enum value using its XmlEnumAttribute. If no XmlEnumAttribute is present, it falls back to enum.ToString().

public static string ToStringUsingXmlEnumAttribute<T>(this T enumValue)
    where T: struct, IConvertible
{
    if (!typeof(T).IsEnum)
    {
        throw new ArgumentException("T must be an enumerated type");
    }

    string name;

    var type = typeof(T);

    var memInfo = type.GetMember(enumValue.ToString());

    if (memInfo.Length == 1)
    {
        var attributes = memInfo[0].GetCustomAttributes(typeof(System.Xml.Serialization.XmlEnumAttribute), false);

        if (attributes.Length == 1)
        {
            name = ((System.Xml.Serialization.XmlEnumAttribute)attributes[0]).Name;
        }
        else
        {
            name = enumValue.ToString();
        }
    }
    else
    {
        name = enumValue.ToString();
    }

    return name;
}

I think you might be able to use the ExpandProperty parameter of Select-Object.

For example, to get the list of the current directory and just have the Name property displayed, one would do the following:

ls | select -Property Name

This is still returning DirectoryInfo or FileInfo objects. You can always inspect the type coming through the pipeline by piping to Get-Member (alias gm).

ls | select -Property Name | gm

So, to expand the object to be that of the type of property you're looking at, you can do the following:

ls | select -ExpandProperty Name

In your case, you can just do the following to have a variable be an array of strings, where the strings are the Name property:

$objects = ls | select -ExpandProperty Name

You can use awk, sort & uniq to do this, for example to list all the unique values in the first column

awk < test.txt '{print $1}' | sort | uniq

As posted elsewhere, if you want to count the number of instances of something you can pipe the unique list into wc -l

extern "C" doesn't really change the way that the compiler reads the code. If your code is in a .c file, it will be compiled as C, if it is in a .cpp file, it will be compiled as C++ (unless you do something strange to your configuration).

What extern "C" does is affect linkage. C++ functions, when compiled, have their names mangled -- this is what makes overloading possible. The function name gets modified based on the types and number of parameters, so that two functions with the same name will have different symbol names.

Code inside an extern "C" is still C++ code. There are limitations on what you can do in an extern "C" block, but they're all about linkage. You can't define any new symbols that can't be built with C linkage. That means no classes or templates, for example.

extern "C" blocks nest nicely. There's also extern "C++" if you find yourself hopelessly trapped inside of extern "C" regions, but it isn't such a good idea from a cleanliness perspective.

Now, specifically regarding your numbered questions:

Regarding #1: __cplusplus will stay defined inside of extern "C" blocks. This doesn't matter, though, since the blocks should nest neatly.

Regarding #2: __cplusplus will be defined for any compilation unit that is being run through the C++ compiler. Generally, that means .cpp files and any files being included by that .cpp file. The same .h (or .hh or .hpp or what-have-you) could be interpreted as C or C++ at different times, if different compilation units include them. If you want the prototypes in the .h file to refer to C symbol names, then they must have extern "C" when being interpreted as C++, and they should not have extern "C" when being interpreted as C -- hence the #ifdef __cplusplus checking.

To answer your question #3: functions without prototypes will have C++ linkage if they are in .cpp files and not inside of an extern "C" block. This is fine, though, because if it has no prototype, it can only be called by other functions in the same file, and then you don't generally care what the linkage looks like, because you aren't planning on having that function be called by anything outside the same compilation unit anyway.

For #4, you've got it exactly. If you are including a header for code that has C linkage (such as code that was compiled by a C compiler), then you must extern "C" the header -- that way you will be able to link with the library. (Otherwise, your linker would be looking for functions with names like _Z1hic when you were looking for void h(int, char)

5: This sort of mixing is a common reason to use extern "C", and I don't see anything wrong with doing it this way -- just make sure you understand what you are doing.

RewriteBase is only useful in situations where you can only put a .htaccess at the root of your site. Otherwise, you may be better off placing your different .htaccess files in different directories of your site and completely omitting the RewriteBase directive.

Lately, for complex sites, I've been taking them out, because it makes deploying files from testing to live just one more step complicated.

All of the answers address the question posed in the title. However, I would like to add a caveat that is implicit in the text. Bézier patches are used to represent the surface, but you cannot just transform the points of the patch and tessellate the patch into polygons, because this will result in distorted geometry. You can, however, tessellate the patch first into polygons using a transformed screen tolerance and then transform the polygons, or you can convert the Bézier patches to rational Bézier patches, then tessellate those using a screen-space tolerance. The former is easier, but the latter is better for a production system.

I suspect that you want the easier way. For this, you would scale the screen tolerance by the norm of the Jacobian of the inverse perspective transformation and use that to determine the amount of tessellation that you need in model space (it might be easier to compute the forward Jacobian, invert that, then take the norm). Note that this norm is position-dependent, and you may want to evaluate this at several locations, depending on the perspective. Also remember that since the projective transformation is rational, you need to apply the quotient rule to compute the derivatives.

All you need is a reluctant quantifier:

regex: /aa.*?aa/

aabbabcaabda   => aabbabcaa

aaaaaabda      => aaaa

aabbabcaabda   => aabbabcaa

aababaaaabdaa  => aababaa, aabdaa

You could use negative lookahead, too, but in this case it's just a more verbose way accomplish the same thing. Also, it's a little trickier than gpojd made it out to be. The lookahead has to be applied at each position before the dot is allowed to consume the next character.

/aa(?:(?!aa).)*aa/

As for the approach suggested by Claudiu and finnw, it'll work okay when the sentinel string is only two characters long, but (as Claudiu acknowledged) it's too unwieldy for longer strings.

Simple.... use tapku library.... you can google that word and use it... its open source... enjoy..... no need of bugging with those codes....

Along with the SHA-1 id of the commit, date and time of the server time would have helped?

Something like this:

commit happened at 11:30:25 on 19 aug 2013 would show as 6886bbb7be18e63fc4be68ba41917b48f02e09d7_19aug2013_113025

This will get the index of the selected option on change:

$('select').change(function(){_x000D_
    console.log($('option:selected',this).index()); _x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

<option value="0">Select Saved Payment Method:</option>_x000D_
<option value="1846">test  xxxx1234</option>_x000D_
<option value="1962">test2  xxxx3456</option>_x000D_
</select>

java.lang.StringBuilder. Use int constructor to create an initial size.

The standard ConfigParser normally requires access via config['section_name']['key'], which is no fun. A little modification can deliver attribute access:

class AttrDict(dict):
    def __init__(self, *args, **kwargs):
        super(AttrDict, self).__init__(*args, **kwargs)
        self.__dict__ = self

AttrDict is a class derived from dict which allows access via both dictionary keys and attribute access: that means a.x is a['x']

We can use this class in ConfigParser:

config = configparser.ConfigParser(dict_type=AttrDict)
config.read('application.ini')

and now we get application.ini with:

[general]
key = value

as

>>> config._sections.general.key
'value'

While taking the advice above with schtasks, you can see in the UI what must be done to perform an hourly task. When you edit trigger begin the task on a schedule, One Time (this is the key). Then you can select "Repeat task every:" 1 hour or whatever you wish. See screenshot:

Not my code, but I think it's pretty nicely written. It allows to check by the key as well as by the Object element itself and handles both the On Error method and iterating through all Collection elements.

To address the question more generally...

Keep in mind that using synchronized on methods is really just shorthand (assume class is SomeClass):

synchronized static void foo() {
    ...
}

is the same as

static void foo() {
    synchronized(SomeClass.class) {
        ...
    }
}

and

synchronized void foo() {
    ...
}

is the same as

void foo() {
    synchronized(this) {
        ...
    }
}

You can use any object as the lock. If you want to lock subsets of static methods, you can

class SomeClass {
    private static final Object LOCK_1 = new Object() {};
    private static final Object LOCK_2 = new Object() {};
    static void foo() {
        synchronized(LOCK_1) {...}
    }
    static void fee() {
        synchronized(LOCK_1) {...}
    }
    static void fie() {
        synchronized(LOCK_2) {...}
    }
    static void fo() {
        synchronized(LOCK_2) {...}
    }
}

(for non-static methods, you would want to make the locks be non-static fields)

I guess problem is in width attributes in table and td remove 'px' for example

I just came across the same issue, and solved it, but not before I found this post. And seeing as your question wasn't really answered, here's my solution (which will hopefully work for you, or anyone else searching for the same thing I did;

Instead of;

... AND WPP.COMMENT NOT LIKE '%CORE%' ...

Try;

... AND NOT WPP.COMMENT LIKE '%CORE%' ...

Basically moving the "NOT" the other side of the field I was evaluating worked for me.

From perlfaq8:

How can I sleep() or alarm() for under a second?

If you want finer granularity than the 1 second that the sleep() function provides, the easiest way is to use the select() function as documented in select in perlfunc. Try the Time::HiRes and the BSD::Itimer modules (available from CPAN, and starting from Perl 5.8 Time::HiRes is part of the standard distribution).

df = df.replace({np.nan: None})

Credit goes to this guy here on this Github issue.

For me android:focusableInTouchMode="true" is the way to go. android:listSelector="@android:color/transparent" is of no use. Note that I am using a custom listview with a number of objects in each row.

You can truncate the date

SELECT *
FROM Table1
WHERE trunc(field1) = to_Date('2012-01-01','YYY-MM-DD')

Look at the SQL Fiddle for more examples.

You can also try in a loop:

for col in df.columns: 
    print(col) 

I had the same problem. Here are the steps for Windows 10 users.

Open CMD: win+r then type cmd. Now,

1. Type pip install virtualenv
2. Create a Virtual Environment, Type virtualenv testopencv
3. Get Inside testopencv, Type cd testopencv
4. Activate the Virtual Environment, Type .\Scripts\activate
5. Now Install Opencv, Type pip install opencv-contrib-python --upgrade
6. Let's test Opencv, Type Python then import cv2 hit enter then type print(cv2.__version__) to check if its installed

Now, open a new cmd, win + r then type cmd, repeat step 6. If it gives you an error.

Go inside the testopencv folder, inside lib. Copy everything, go to your python directory, inside lib folder paste it and skip that are already present.

Again open a new cmd, repeat Step 6.

Hope it helps.

I know I'm a bit late for that one, but I'll share what I did too, in case it helps someone else :

HashMap<String, HashMap> selects = new HashMap<String, HashMap>();

for(Map.Entry<String, HashMap> entry : selects.entrySet()) {
    String key = entry.getKey();
    HashMap value = entry.getValue();

    // do what you have to do here
    // In your case, another loop.
}

I've tried making an object and tried using .getWidth and .getHeight but can't get it to work.

That´s because you are not setting the width and height fields in JFrame, but you are setting them on local variables. Fields HEIGHT and WIDTH are inhereted from ImageObserver

Fields inherited from interface java.awt.image.ImageObserver
ABORT, ALLBITS, ERROR, FRAMEBITS, HEIGHT, PROPERTIES, SOMEBITS, WIDTH

See http://java.sun.com/javase/6/docs/api/javax/swing/JFrame.html

If width and height represent state of the frame, then you could refactorize them to fields, and write getters for them.

Then, you could create a Constructor that receives both values as parameters

public class DrawFrame extends JFrame {
 private int width;
 private int height;

 DrawFrame(int _width, int _height){

   this.width = _width;
   this.height = _height;

   //other stuff here
}
 public int getWidth(){}
 public int getHeight(){}

 //other methods
}

If widht and height are going to be constant (after created) then you should use the final modifier. This way, once they are assigned a value, they can´t be modified.

Also, the variables i use in DrawCircle, should I have them in the constructor or not?

The way it is writen now, will only allow you to create one type of circle. If you wan´t to create different circles, you should overload the constructor with one with arguments).

For example, if you want to change the attributes xPoint and yPoint, you could have a constructor

public DrawCircle(int _xpoint, int _ypoint){
  //build circle here.
 }

EDIT:

Where does _width and _height come from?

Those are arguments to constructors. You set values on them when you call the Constructor method.

In DrawFrame I set width and height. In DrawCircle I need to access the width and height of DrawFrame. How do I do this?

DrawFrame(){
   int width = 400;
   int height =400;

   /*
   * call DrawCircle constructor
   */
   content.pane(new DrawCircle(width,height));

   // other stuff

}

Now when the DrawCircle constructor executes, it will receive the values you used in DrawFrame as _width and _height respectively.

EDIT:

Try doing

 DrawFrame frame = new DrawFrame();//constructor contains code on previous edit.
 frame.setPreferredSize(new Dimension(400,400));

Welcome BrowserDetect - an awesome function.

<script>
    var BrowserDetect;
    BrowserDetect = {...};//  get BrowserDetect Object from the link referenced in this answer
    BrowserDetect.init();
    // On page load, detect browser (with jQuery or vanilla)
    if (BrowserDetect.browser === 'Explorer') {
      // Add 'ie' class on every element on the page.
      $('*').addClass('ie');
    }
</script>

<!-- ENSURE IE STYLES ARE AVAILABLE -->
<style>
    div.ie {
       // do something special for div on IE browser.
    }
    h1.ie {
     // do something special for h1 on IE browser.
    }
</style>

The Object BrowserDetect also provides version info so we can add specific classes - for ex. $('*').addClass('ie9'); if (BrowserDetect.version == 9).

Good Luck....

The || operator is "concatenate" - it joins together the two strings of its operands.

From http://www.sqlite.org/lang_expr.html

For padding, the seemingly-cheater way I've used is to start with your target string, say '0000', concatenate '0000423', then substr(result, -4, 4) for '0423'.

Update: Looks like there is no native implementation of "lpad" or "rpad" in SQLite, but you can follow along (basically what I proposed) here: http://verysimple.com/2010/01/12/sqlite-lpad-rpad-function/

-- the statement below is almost the same as
-- select lpad(mycolumn,'0',10) from mytable

select substr('0000000000' || mycolumn, -10, 10) from mytable

-- the statement below is almost the same as
-- select rpad(mycolumn,'0',10) from mytable

select substr(mycolumn || '0000000000', 1, 10) from mytable

Here's how it looks:

SELECT col1 || '-' || substr('00'||col2, -2, 2) || '-' || substr('0000'||col3, -4, 4)

it yields

"A-01-0001"
"A-01-0002"
"A-12-0002"
"C-13-0002"
"B-11-0002"

If we wanted to retrieve or update these attributes using existing, native JavaScript, then we can do so using the getAttribute and setAttribute methods as shown below:

JavaScript

<script>
// 'Getting' data-attributes using getAttribute
var plant = document.getElementById('strawberry-plant');
var fruitCount = plant.getAttribute('data-fruit'); // fruitCount = '12'

// 'Setting' data-attributes using setAttribute
plant.setAttribute('data-fruit','7'); // Pesky birds
</script>

Through jQuery

// Fetching data
var fruitCount = $(this).data('fruit');

// Above does not work in firefox. So use below to get attribute value.
var fruitCount = $(this).attr('data-fruit');

// Assigning data
$(this).data('fruit','7');

// But when you get the value again, it will return old value. 
// You have to set it as below to update value. Then you will get updated value.
$(this).attr('data-fruit','7'); 

Read this documentation for vanilla js or this documentation for jquery

Let's assume that you are supposed to write a program to control a nuclear power-plant. It is pretty obvious that even the most minor mistake could have catastrophic results, therefore your code has to be bug-free (assuming that the JVM is bug-free for the sake of the argument).

Java is not a verifiable language, which means: you cannot calculate that the result of your operation will be perfect. The main reason for this are pointers: they can point anywhere or nowhere, therefore they cannot be calculated to be of this exact value, at least not within a reasonable span of code. Given this problem, there is no way to prove that your code is correct at a whole. But what you can do is to prove that you at least find every bug when it happens.

This idea is based on the Design-by-Contract (DbC) paradigm: you first define (with mathematical precision) what your method is supposed to do, and then verify this by testing it during actual execution. Example:

// Calculates the sum of a (int) + b (int) and returns the result (int).
int sum(int a, int b) {
  return a + b;
}

While this is pretty obvious to work fine, most programmers will not see the hidden bug inside this one (hint: the Ariane V crashed because of a similar bug). Now DbC defines that you must always check the input and output of a function to verify that it worked correctly. Java can do this through assertions:

// Calculates the sum of a (int) + b (int) and returns the result (int).
int sum(int a, int b) {
    assert (Integer.MAX_VALUE - a >= b) : "Value of " + a + " + " + b + " is too large to add.";
  final int result = a + b;
    assert (result - a == b) : "Sum of " + a + " + " + b + " returned wrong sum " + result;
  return result;
}

Should this function now ever fail, you will notice it. You will know that there is a problem in your code, you know where it is and you know what caused it (similar to Exceptions). And what is even more important: you stop executing right when it happens to prevent any further code to work with wrong values and potentially cause damage to whatever it controls.

Java Exceptions are a similar concept, but they fail to verify everything. If you want even more checks (at the cost of execution speed) you need to use assertions. Doing so will bloat your code, but you can in the end deliver a product at a surprisingly short development time (the earlier you fix a bug, the lower the cost). And in addition: if there is any bug inside your code, you will detect it. There is no way of a bug slipping-through and cause issues later.

This still is not a guarantee for bug-free code, but it is much closer to that, than usual programs.

You could use the printf(1) command, e.g. like

printf "Hello times %d\nHere\n" $[2+3] 

The  printf command may accept arguments and needs a format control string similar (but not exactly the same) to the one for the standard C printf(3) function...

I think I know the reason for this exception. You might be running this code snippet in multiple threads.

It is happened to me with laravel 5.1 on php-7 when I was running bunch of unitests.

The solution was - to change memory_limit in php.ini but it should be correct one. So you need one responsible for server, located there:

/etc/php/7.0/cli/php.ini

so you need a line with

 memory_limit

After that you need to restart php service

sudo service php7.0-fpm restart

to check if it was changed successfully I used command line to run this:

 php -i

the report contained following line

memory_limit => 2048M => 2048M

Now test cases are fine.

with jQuery its even easier and works on Chrome as well

$('#your-button').on('click', function(){
       $('<a href="https://www.some-page.com" target="blank"></a>')[0].click();    
})

Look at the responseText property of the request parameter.

Just a regular-expression based alternative. Not that fast, not that good.

Pattern pattern = Pattern.compile("\\.([^.]*)$");
Matcher matcher = pattern.matcher(fileName);

if (matcher.find()) {
    String ext = matcher.group(1);
}

I have just written the following:

public static String toDelimitedString(int[] ids, String delimiter)
{
    StringBuffer strb = new StringBuffer();
    for (int id : ids)
    {
      strb.append(String.valueOf(id) + delimiter);
    }
    return strb.substring(0, strb.length() - delimiter.length());
 }

IEnumerable
You should try and use the least specific type that suits your purpose.
IEnumerable is less specific than IList.
You use IEnumerable when you want to loop through the items in a collection.

IList
IList implements IEnumerable.
You should use IList when you need access by index to your collection, add and delete elements, etc...

List
List implements IList.

You can remove illegal chars using Linq like this:

var invalidChars = Path.GetInvalidFileNameChars();

var invalidCharsRemoved = stringWithInvalidChars
.Where(x => !invalidChars.Contains(x))
.ToArray();

EDIT
This is how it looks with the required edit mentioned in the comments:

var invalidChars = Path.GetInvalidFileNameChars();

string invalidCharsRemoved = new string(stringWithInvalidChars
  .Where(x => !invalidChars.Contains(x))
  .ToArray());

I tried several solutions and here is the simplest I personally found.
Dan pointed out in the comments that the original post belongs to Oleg Sych—thanks, Oleg!

Here are the instructions:

1. Add an XML file for each configuration to the project.

Typically you will have Debug and Release configurations so name your files App.Debug.config and App.Release.config. In my project, I created a configuration for each kind of environment, so you might want to experiment with that.

2. Unload project and open .csproj file for editing

Visual Studio allows you to edit .csproj files right in the editor—you just need to unload the project first. Then right-click on it and select Edit <ProjectName>.csproj.

3. Bind App.*.config files to main App.config

Find the project file section that contains all App.config and App.*.config references. You'll notice their build actions are set to None:

<None Include="App.config" />
<None Include="App.Debug.config" />
<None Include="App.Release.config" />

First, set build action for all of them to Content.
Next, make all configuration-specific files dependant on the main App.config so Visual Studio groups them like it does designer and code-behind files.

Replace XML above with the one below:

<Content Include="App.config" />
<Content Include="App.Debug.config" >
  <DependentUpon>App.config</DependentUpon>
</Content>
<Content Include="App.Release.config" >
  <DependentUpon>App.config</DependentUpon>
</Content>

4. Activate transformations magic (only necessary for Visual Studio versions pre VS2017)

In the end of file after

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

and before final

</Project>

insert the following XML:

  <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
  <Target Name="CoreCompile" Condition="exists('app.$(Configuration).config')">
    <!-- Generate transformed app config in the intermediate directory -->
    <TransformXml Source="app.config" Destination="$(IntermediateOutputPath)$(TargetFileName).config" Transform="app.$(Configuration).config" />
    <!-- Force build process to use the transformed configuration file from now on. -->
    <ItemGroup>
      <AppConfigWithTargetPath Remove="app.config" />
      <AppConfigWithTargetPath Include="$(IntermediateOutputPath)$(TargetFileName).config">
        <TargetPath>$(TargetFileName).config</TargetPath>
      </AppConfigWithTargetPath>
    </ItemGroup>
  </Target>

Now you can reload the project, build it and enjoy App.config transformations!

FYI

Make sure that your App.*.config files have the right setup like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
     <!--magic transformations here-->
</configuration>

It would appear that the ADB daemon on the device (adbd) is disagreeing with the ADB server process on your host computer as to which version of the protocol they are speaking. Which version of the SDK are you running and what is the OS version on the device you are debugging?

What you might need to do is actually downgrade your version of the SDK tools so that the ADB daemon and process are in agreement. I thought the server process was completely backward compatible, but this could be one of those corner cases where it doesn't. Google doesn't advertise the fact that you can get their old SDK tools packages, but they can be found by looking in the archives area at http://developer.android.com.

use a HEREDOC, which eliminates any need to swap quote types and/or escape them:

echo <<<EOL
<script>$('#edit_errors').html('<h3><em><font color="red">Please Correct Errors Before Proceeding</font></em></h3>')</script>
EOL;

They change it again. At this moment documentation does not fit actual situation.

Commonly all works as expected with one small difference. Login from Devices config now moves to Products -> Facebook Login.

So you need to:

• get your App id from headline,
• get Client Token from app Settings -> Advanced. There is also Native or desktop app? question/config. I turn it on.
• Add product (just click on Add product and then Get started on Facebook login. Move back to your app config, click to newly added Facebook login and you'll see your Login from Devices config.

I've seen this behavior today when the

   <service name="A.B.C.D" behaviorConfiguration="returnFaults">
        <endpoint contract="A.B.C.ID" binding="basicHttpBinding" address=""/>
    </service>

was missing from the web.config. The service.svc file was there and got served. It took a while to realize that the problem was not in the binding configuration it self...

Please take a look here:

• RS-232 for Linux and Windows ¹⁾
• Windows Serial Port Programming ²⁾
• Using the Serial Ports in Visual C++ ³⁾
• Serial Communication in Windows

¹⁾ You can use this with Windows (incl. MinGW) as well as Linux. Alternative you can only use the code as an example.

²⁾ Step-by-step tutorial how to use serial ports on windows

³⁾ You can use this literally on MinGW

Here's some very, very simple code (without any error handling or settings):

#include <windows.h>

/* ... */


// Open serial port
HANDLE serialHandle;

serialHandle = CreateFile("\\\\.\\COM1", GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0);

// Do some basic settings
DCB serialParams = { 0 };
serialParams.DCBlength = sizeof(serialParams);

GetCommState(serialHandle, &serialParams);
serialParams.BaudRate = baudrate;
serialParams.ByteSize = byteSize;
serialParams.StopBits = stopBits;
serialParams.Parity = parity;
SetCommState(serialHandle, &serialParams);

// Set timeouts
COMMTIMEOUTS timeout = { 0 };
timeout.ReadIntervalTimeout = 50;
timeout.ReadTotalTimeoutConstant = 50;
timeout.ReadTotalTimeoutMultiplier = 50;
timeout.WriteTotalTimeoutConstant = 50;
timeout.WriteTotalTimeoutMultiplier = 10;

SetCommTimeouts(serialHandle, &timeout);

Now you can use WriteFile() / ReadFile() to write / read bytes. Don't forget to close your connection:

CloseHandle(serialHandle);

You don't need jQuery for this, as simple javascript will suffice:

alert(document.domain);

See it in action:

console.log("Output;");  
console.log(location.hostname);
console.log(document.domain);
alert(window.location.hostname)

console.log("document.URL : "+document.URL);
console.log("document.location.href : "+document.location.href);
console.log("document.location.origin : "+document.location.origin);
console.log("document.location.hostname : "+document.location.hostname);
console.log("document.location.host : "+document.location.host);
console.log("document.location.pathname : "+document.location.pathname);

for more details click here window.location

just append "http://" before domain name to get appropriate result.

It's about how much type-safety you want to impose.

When you write (bar) foo (which is equivalent to reinterpret_cast<bar> foo if you haven't provided a type conversion operator) you are telling the compiler to ignore type safety, and just do as it's told.

When you write static_cast<bar> foo you are asking the compiler to at least check that the type conversion makes sense and, for integral types, to insert some conversion code.

Errors

I wanted to address the error's people are getting. Because the errors drove me nuts too... On a mac if you install xattr in python, then your environment may have an issue.

There are two different paths on my mac for xattr

type -a xattr

    # xattr is /usr/local/bin/xattr    # PYTHON Installed Version
    # xattr is /usr/bin/xattr          # Mac OSX Installed Version

So in one of the example's where -c will not work in xargs is because in bash you default to the non-python version.

Works with -c

/usr/bin/xattr -c

Does NOT Work with -c

/usr/local/bin/xattr -c
    # option -c not recognized

My Shell/Terminal defaults to /usr/local/bin/xattr because my $PATH /usr/local/bin: is before /usr/bin: which I believe is the default.

I can prove this because, if you try to uninstall the python xattr you will see:

pip3 uninstall xattr
Uninstalling xattr-0.9.6:
  Would remove:
    /usr/local/bin/xattr
    /usr/local/lib/python3.7/site-packages/xattr-0.9.6.dist-info/*
    /usr/local/lib/python3.7/site-packages/xattr/*
Proceed (y/n)?

Workarounds

To Fix option -c not recognized Errors.

1. Uninstall any Python xattr you may have: pip3 uninstall xattr
2. Close all Terminal windows & quit Terminal
3. Reopen a new Terminal window.
4. ReRun xattr command and it should now work.

OR

If you want to keep the Python xattr then use

/usr/bin/xattr

for any Shell commands in Terminal

Example:

Python's version of xattr doesn't handle images at all:

Use the ListView.ItemContainerStyle property to give your ListViewItems an EventSetter that will handle the PreviewMouseLeftButtonDown event. Then, in the handler, check to see if the item that was clicked is selected.

XAML:

<ListView ItemsSource={Binding MyItems}>
    <ListView.View>
        <GridView>
            <!-- declare a GridViewColumn for each property -->
        </GridView>
    </ListView.View>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListViewItem_PreviewMouseLeftButtonDown" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

Code-behind:

private void ListViewItem_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    var item = sender as ListViewItem;
    if (item != null && item.IsSelected)
    {
        //Do your stuff
    }
}

You can try this to simple date format valdation

 public Date validateDateFormat(String dateToValdate) {

    SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy HHmmss");
