You have to replace string line

QString line = in.readLine();

into while:

QFile file("/home/hamad/lesson11.txt");
if(!file.open(QIODevice::ReadOnly)) {
    QMessageBox::information(0, "error", file.errorString());
}

QTextStream in(&file);

while(!in.atEnd()) {
    QString line = in.readLine();    
    QStringList fields = line.split(",");    
    model->appendRow(fields);    
}

file.close();

You can do it programmatically:

#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdlib.h>

int main() {
    int fd = creat("/tmp/foo.txt", 0644);
    ftruncate(fd, SIZE_IN_BYTES);
    close(fd);
    return 0;
}

This approach is especially useful to subsequently mmap the file into memory.

use the following command to check that the file has the correct size:

# du -B1 --apparent-size /tmp/foo.txt

Be careful:

# du /tmp/foo.txt

will probably print 0 because it is allocated as Sparse file if supported by your filesystem.

see also: man 2 open and man 2 truncate

I see 2 possible problems:

Problem 1

• the XMLHTTPRequest object has not finished loading the data at the time you are trying to use it

Solution: assign a callback function to the objects "onreadystatechange" -event and handle the data in that function

xmlhttp.onreadystatechange = callbackFunctionName;

Once the state has reached DONE (4), the response content is ready to be read.

Problem 2

• the XMLHTTPRequest object does not exist in all browsers (by that name)

Solution: Either use a try-catch for creating the correct object for correct browser ( ActiveXObject in IE) or use a framework, for example jQuery ajax-method

Note: if you decide to use jQuery ajax-method, you assign the callback-function with jqXHR.done()

I would recommend using a cursor. A cursor fetch is always a single row (unless you use a bulk collection), and cursors do not automatically throw no_data_found or too_many_rows exceptions; although you may inspect the cursor attribute once opened to determine if you have a row and how many.

declare
v_column my_table.column%type;
l_count pls_integer;
cursor my_cursor is
  select count(*) from my_table where ...;

begin
  open my_cursor;
    fetch my_cursor into l_count;
  close my_cursor;

  if l_count = 1 then
    select whse_code into v_column from my_table where ...;
  else
    v_column := null;
  end if;
end;

Or, even more simple:

    declare
    v_column my_table.column%type;
    cursor my_cursor is
      select column from my_table where ...;

    begin
      open my_cursor;
        fetch my_cursor into v_column;
        -- Optional IF .. THEN based on FOUND or NOTFOUND
        -- Not really needed if v_column is not set
        if my_cursor%notfound then
          v_column := null;
        end if;
      close my_cursor;
    end;

The ruby version 1.8.7 seems to be your system ruby.

Normally you can choose the ruby version you'd like, if you are using rvm with following. Simple change into your directory in a new terminal and type in:

rvm use 2.0.0

You can find more details about rvm here: http://rvm.io Open the website and scroll down, you will see a few helpful links. "Setting up default rubies" for example could help you.

Update: To set the ruby as default:

rvm use 2.0.0 --default

You can also use:

@Scripts.RenderFormat("<script type=\"text/javascript\" src=\"{0}\"></script>", "~/bundles/mybundle")

To specify the format of your output in a scenario where you need to use Charset, Type, etc.

I'm a fan of:

chooseCRANmirror()

Which will print the list of mirrors in the output (no worrying a popup window since you are running it from the terminal) and then you enter the number you want.

You miss the from clause

SELECT *  from TCCAWZTXD.TCC_COIL_DEMODATA WHERE CURRENT_INSERTTIME  BETWEEN(CURRENT_TIMESTAMP)-5 minutes AND CURRENT_TIMESTAMP

Its much better to use java.util.LinkedList, because it's probably much more optimized, than the one that you will write.

You can use the Enumerable.SequenceEqual() in the System.Linq to compare the contents in the array

bool isEqual = Enumerable.SequenceEqual(target1, target2);

With SharePoint 2013 new library, I managed to do something like this:

private void UploadToSharePoint(string p, out string newUrl)  //p is path to file to load
{
    string siteUrl = "https://myCompany.sharepoint.com/site/";
    //Insert Credentials
    ClientContext context = new ClientContext(siteUrl);

    SecureString passWord = new SecureString();
    foreach (var c in "mypassword") passWord.AppendChar(c);
    context.Credentials = new SharePointOnlineCredentials("myUserName", passWord);
    Web site = context.Web;

    //Get the required RootFolder
    string barRootFolderRelativeUrl = "Shared Documents/foo/bar";
    Folder barFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl);

    //Create new subFolder to load files into
    string newFolderName = baseName + DateTime.Now.ToString("yyyyMMddHHmm");
    barFolder.Folders.Add(newFolderName);
    barFolder.Update();

    //Add file to new Folder
    Folder currentRunFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl + "/" + newFolderName);
    FileCreationInformation newFile = new FileCreationInformation { Content = System.IO.File.ReadAllBytes(@p), Url = Path.GetFileName(@p), Overwrite = true };
    currentRunFolder.Files.Add(newFile);
    currentRunFolder.Update();

    context.ExecuteQuery();

    //Return the URL of the new uploaded file
    newUrl = siteUrl + barRootFolderRelativeUrl + "/" + newFolderName + "/" + Path.GetFileName(@p);
}

We don't have option to truncate dynamo tables. we have to drop the table and create again . DynamoDB Charges are based on ReadCapacityUnits & WriteCapacityUnits . If we delete all items using BatchWriteItem function, it will use WriteCapacityUnits.So better to delete specific records or delete the table and start again .

Maybe this is cheating, but it works!

I also needed a table that is the source for a graph, and I didn't want any blank or zero cells to produce a point on the graph. It is true that you need to set the graph property, select data, hidden and empty cells to "show empty cells as Gaps" (click the radio button). That's the first step.

Then in the cells that may end up with a result that you don't want plotted, put the formula in an IF statement with an NA() results such as =IF($A8>TODAY(),NA(), *formula to be plotted*)

This does give the required graph with no points when an invalid cell value occurs. Of course this leaves all cells with that invalid value to read #N/A, and that's messy.

To clean this up, select the cell that may contain the invalid value, then select conditional formatting - new rule. Select 'format only cells that contain' and under the rule description select 'errors' from the drop down box. Then under format select font - colour - white (or whatever your background colour happens to be). Click the various buttons to get out and you should see that cells with invalid data look blank (they actually contain #N/A but white text on a white background looks blank.) Then the linked graph also does not display the invalid value points.

Perhaps the project's type table is in an incorrect state. I would try to remove/add the reference and if that didn't work, create another project, import my code, and see if that works.

I ran into this while using VS 2005, one would expect MS to have fixed that particular problem by now though..

success is the callback that is invoked when the request is successful and is part of the $.ajax call. done is actually part of the jqXHR object returned by $.ajax(), and replaces success in jQuery 1.8.

I had also similar problem where by I had to un-install JDK 1.8 and needed jdk 1.7. What i did was removed the symbolic links from the javapath and then imported the shortcuts of java, javaw, javaws from the bin directory to the javapath folder. However, I found some permission issues in the enterprise laptop where by I did not have the privilege to modify/ update this directory. I had given appropriate permission from the administrator and there by resolved it.

If the above answers don't work, try:

os.environ['CUDA_VISIBLE_DEVICES'] = '-1'

contextlib.nested supports this:

import contextlib

with contextlib.nested(open("out.txt","wt"), open("in.txt")) as (file_out, file_in):

   ...

Update:
To quote the documentation, regarding contextlib.nested:

Deprecated since version 2.7: The with-statement now supports this functionality directly (without the confusing error prone quirks).

See Rafal Dowgird's answer for more information.

Here how to do it using format()

print "bin_signedDate : ", ''.join(format(x, '08b') for x in bytevector)

It is important the 08b . That means it will be a maximum of 8 leading zeros be appended to complete a byte. If you don't specify this then the format will just have a variable bit length for each converted byte.

DataFrames are based on RDDs. RDDs are immutable structures and do not allow updating elements on-site. To change values, you will need to create a new DataFrame by transforming the original one either using the SQL-like DSL or RDD operations like map.

A highly recommended slide deck: Introducing DataFrames in Spark for Large Scale Data Science.

Implement custom readonly like eventHandler

<select id='country' data-changeable=false>
  <option selected value="INDIA">India</option>
  <option value="USA">United States</option>
  <option value="UK">United Kingdom</option>
</select>

<script>
    var lastSelected = $("#country option:selected");

    $("#country").on("change", function() {
       if(!$(this).data(changeable)) {
            lastSelected.attr("selected", true);              
       }

    $("#country").on("click", function() {
       lastSelected = $("#country option:selected");

ACE.oledb.16.0 dosen't work in the 64-bit os

download patch from https://www.microsoft.com/en-us/download/details.aspx?id=13255

Prerequisite

using System.Linq;

then ...

string res = string.Join(Environment.NewLine, 
    results.Rows.OfType<DataRow>().Select(x => string.Join(" ; ", x.ItemArray)));

For Example:
$parent_category_name = Men's Clothing
Consider here the SQL query

$sql_category_name = "SELECT c.*, cd.name, cd.category_id  as iid FROM ". DB_PREFIX . "category c LEFT JOIN " . DB_PREFIX . "category_description cd ON (c.category_id = cd.category_id) WHERE cd.name = '" .  $this->db->escape($parent_category_name) . "' AND c.parent_id =0 "; 

Error:

Static analysis:

1 errors were found during analysis.

Ending quote ' was expected. (near "" at position 198)
SQL query: Documentation

SELECT c.*, cd.name, cd.category_id as iid FROM oc_category c LEFT JOIN oc_category_description cd ON (c.category_id = cd.category_id) WHERE cd.name = 'Men's Clothing' AND c.parent_id =0 LIMIT 0, 25

MySQL said: Documentation

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's Clothing' AND c.parent_id =0 LIMIT 0, 25' at line 1

Try to implement:

$this->db->escape($parent_category_name)

The above method works on OpenCart framework. Find your framework & implement OR mysql_real_escape_string() in Core PHP

This will become Men\'s Clothing i.e, In my case

$sql_category_name = "SELECT c.*, cd.name, cd.category_id  as iid FROM ". DB_PREFIX . "category c LEFT JOIN " . DB_PREFIX . "category_description cd ON (c.category_id = cd.category_id) WHERE cd.name = '" .  $this->db->escape($parent_category_name) . "' AND c.parent_id =0 "; 

So you'll get the clear picture of the query by implementing escape() as

SELECT c.*, cd.name, cd.category_id as iid FROM oc_category c LEFT JOIN oc_category_description cd ON (c.category_id = cd.category_id) WHERE cd.name = 'Men\'s Clothing' AND c.parent_id =0

GitHub is svn compatible so you can use svn ls

svn ls https://github.com/user/repository.git/branches/master/

BitBucket supports git archive so you can download tar archive and list archived files. It is not very efficient but works:

git archive [email protected]:repository HEAD directory | tar -t

If it's php 7 on ubuntu, try this

apt-get install php7.0-curl
/etc/init.d/apache2 restart

a user-defined function may server better, at least to hide the logic - esp. if you need to do this in more than one query

C# supports two boolean or operators: the single bar | and the double-bar ||.

The difference is that | always checks both the left and right conditions, while || only checks the right-side condition if it's necessary (if the left side evaluates to false).

This is significant when the condition on the right-side involves processing or results in side effects. (For example, if your ErrorDumpWriter.Close method took a while to complete or changed something's state.)

Another fancy possibility is...

User.where("id > :id", id: 100)

This feature allows you to create more comprehensible queries if you want to replace in multiple places, for example...

User.where("id > :id OR number > :number AND employee_id = :employee", id: 100, number: 102, employee: 1205)

This has more meaning than having a lot of ? on the query...

User.where("id > ? OR number > ? AND employee_id = ?", 100, 102, 1205)

In SQL Server Management Studio, go to Object Explorer > (your server) > Security > Logins and right-click New Login:

Then in the dialog box that pops up, pick the types of objects you want to see (Groups is disabled by default - check it!) and pick the location where you want to look for your objects (e.g. use Entire Directory) and then find your AD group.

You now have a regular SQL Server Login - just like when you create one for a single AD user. Give that new login the permissions on the databases it needs, and off you go!

Any member of that AD group can now login to SQL Server and use your database.

the :checked pseudo-class initially applies to such elements that have the HTML4 selected and checked attributes

Source: w3.org

So, this CSS works, although styling the color is not possible in every browser:

option:checked { color: red; }

An example of this in action, hiding the currently selected item from the drop down list.

option:checked { display:none; }

<select>_x000D_
    <option>A</option>_x000D_
    <option>B</option>_x000D_
    <option>C</option>_x000D_
</select>

To style the currently selected option in the closed dropdown as well, you could try reversing the logic:

select { color: red; }
option:not(:checked) { color: black; } /* or whatever your default style is */

if you're using JQuery:

var obj = jQuery.parseJSON('{"path":"/img/filename.jpg"}');
console.log(obj.path); // will print /img/filename.jpg

REMEMBER: eval is evil! :D

If worse comes to worse, you can create an interface and adapter pair. You would change all uses of ConcreteClass to use the interface instead, and always pass the adapter instead of the concrete class in production code.

The adapter implements the interface, so the mock can also implement the interface.

It's more scaffolding than just making a method virtual or just adding an interface, but if you don't have access to the source for the concrete class it can get you out of a bind.

You can't pass objects using router params, only strings because it needs to be reflected in the URL. It would be probably a better approach to use a shared service to pass data around between routed components anyway.

The old router allows to pass data but the new (RC.1) router doesn't yet.

Update

data was re-introduced in RC.4 How do I pass data in Angular 2 components while using Routing?

Try this :

<style type="text/css">
        .myTableStyle
        {
           position:absolute;
           top:50%;
           left:50%; 

            /*Alternatively you could use: */
           /*
              position: fixed;
               bottom: 50%;
               right: 50%;
           */


        }
    </style>

The links are wrong, you have to do this:

<ul class="nav navbar-nav item">
    <li>
        <a [routerLink]="['/home']" routerLinkActive="active">Home</a>
    </li>
    <li>
        <a [routerLink]="['/about']" routerLinkActive="active">About this
        </a>
    </li>
</ul>

Yes, there it is. It's like maxlength. W3.org documentation: http://www.w3.org/TR/html5/forms.html#attr-fe-minlength

In case minlength doesn't work, use the pattern attribute as mentioned by @Pumbaa80 for the input tag.

For textarea: For setting max; use maxlength and for min go to this link.

You will find here both for max and min.

If you are using vue2-google-maps like me, the code to set the size looks like this:

<gmap-marker
  ..
  :icon="{
    ..
    anchor: { x: iconSize, y: iconSize },
    scaledSize: { height: iconSize, width: iconSize },
  }"
>

Following this procedure worked for me.

To create gpg key. gpg --gen-key --homedir /etc/salt/gpgkeys

export the public key, secret key, and secret subkey.

gpg --homedir /etc/salt/gpgkeys --export test-key > pub.key
gpg --homedir /etc/salt/gpgkeys --export-secret-keys test-key > sec.key
gpg --homedir /etc/salt/gpgkeys --export-secret-subkeys test-key > sub.key

Now import the keys using the following command.

gpg --import pub.key
gpg --import sec.key
gpg --import sub.key

Verify if the keys are imported.

gpg --list-keys
gpg --list-secret-keys

Create a sample file.

echo "hahaha" > a.txt

Encrypt the file using the imported key

gpg --encrypt --sign --armor -r test-key a.txt

To decrypt the file, use the following command.

gpg --decrypt a.txt.asc

How about PlantUML? It's not for reverse engineering!!! It's for engineering before you code.

Most people do not read the comments so to summarize (Thanks to @Industrial-antidepressant and @wrecker):

As suggested in a bug ticket you should try the following:

1. Close Android Studio
2. go to android-studio/plugins/gradle/lib
3. Delete (or better move them somewhere to have a backup) all gradle-*-1.8 files
4. Start Android Studio again and rebuild/refresh.

It should work. Make sure to star the above bug ticket to get informed.

Little tip: Try the new compile setting Settings -> Compiler -> Gradle and activate the third in-process build for a speed up. Depending on your project setting you might want to select the first one as well. With that my project build time reduced to 2-4 seconds (before 20+ seconds).

VAL1 and VAL2 need to be dimmed as integer, not as string, to be used as an argument for Cells, which takes integers, not strings, as arguments.

Dim val1 As Integer, val2 As Integer, i As Integer

For i = 1 To 333

  Sheets("Feuil2").Activate
  ActiveSheet.Cells(i, 1).Select

    val1 = Cells(i, 1).Value
    val2 = Cells(i, 2).Value

Sheets("Classeur2.csv").Select
Cells(val1, val2).Select

ActiveCell.FormulaR1C1 = "1"

Next i

As explained in http://www.regular-expressions.info/anchors.html under the section "Strings Ending with a Line Break", \Z will generally match before the end of the last newline in strings that end in a newline. If you want to only match the end of the string, you need to use \z. The exception to this rule is Python.

In other words, to exclusively match an empty string, you need to use /\A\z/.

You can try the following code. It is much more better than the other code.

a = a + b;
b = a - b;
a = a - b;

As was pointed out above, it is primarily a tradeoff between storage and performance. At least in most cases.

However, there is at least one other factor that should be considered when choosing n/varchar(Max) over n/varchar(n). Is the data going to be indexed (such as, say, a last name)? Since the MAX definition is considered a LOB, then anything defined as MAX is not available for indexing. and without an index, any lookup involving the data as predicate in a WHERE clause is going to be forced into a Full Table scan, which is the worst performance you can get for data lookups.

If you want to plot a Pandas dataframe and want to remove the legend, add legend=None as parameter to the plot command.

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

df2 = pd.DataFrame(np.random.randn(10, 5))
df2.plot(legend=None)
plt.show()

I believe that the blog post JavaScript Beginners – Select a dropdown option by value might help you.

<a href="javascript:void(0);" onclick="selectItemByValue(document.getElementById('personlist'),11)">change</a>

function selectItemByValue(elmnt, value){

  for(var i=0; i < elmnt.options.length; i++)
  {
    if(elmnt.options[i].value === value) {
      elmnt.selectedIndex = i;
      break;
    }
  }
}

Does the second query return any results from the 17th, or just from the 18th?

The first query will only return results from the 17th, or midnight on the 18th.

Try this instead

select * 
from LOGS 
where check_in >= CONVERT(datetime,'2013-10-17') 
and check_in< CONVERT(datetime,'2013-10-19')

I'm on mac osx (10.15.3) and new to vim. I found this so frustrating and all the answers on here too complicated and/or didn't apply to my situation. I ended up getting this working in 2 ways:

1. key mapping that uses pbcopy: works on the old version of vim that ships with mac.

   Add vmap '' :w !pbcopy<CR><CR> to your ~/.vimrc
   Now you can visually select and hit '' (two apostrophes) to copy to clipboard

2. Install newer version of vim so I can access the solution most recommended in other answers:

   brew install vim
alias vim=/usr/local/bin/vim (should add this to your ~/.bashrc or equivalent)
   Now you can visually select and hit "+yy to copy to clipboard

In my code I have no direct access to the 'preparedStatement' so I cannot use batch, I just pass it the query and a list of parameters. The trick however is to create a variable length insert statement, and a LinkedList of parameters. The effect is the same as the top example, with variable parameter input length.See below (error checking omitted). Assuming 'myTable' has 3 updatable fields: f1, f2 and f3

String []args={"A","B","C", "X","Y","Z" }; // etc, input list of triplets
final String QUERY="INSERT INTO [myTable] (f1,f2,f3) values ";
LinkedList params=new LinkedList();
String comma="";
StringBuilder q=QUERY;
for(int nl=0; nl< args.length; nl+=3 ) { // args is a list of triplets values
    params.add(args[nl]);
    params.add(args[nl+1]);
    params.add(args[nl+2]);
    q.append(comma+"(?,?,?)");
    comma=",";
}      
int nr=insertIntoDB(q, params);

in my DBInterface class I have:

int insertIntoDB(String query, LinkedList <String>params) {
    preparedUPDStmt = connectionSQL.prepareStatement(query);
    int n=1;
    for(String x:params) {
        preparedUPDStmt.setString(n++, x);
    }
    int updates=preparedUPDStmt.executeUpdate();
    return updates;
}

I would go for aspect-ratio, it offers way more possibilities.

/* Exact aspect ratio */
@media (aspect-ratio: 2/1) {
    ...
}

/* Minimum aspect ratio */
@media (min-aspect-ratio: 16/9) {
    ...
}

/* Maximum aspect ratio */
@media (max-aspect-ratio: 8/5) {
    ...
}

Both, orientation and aspect-ratio depend on the actual size of the viewport and have nothing todo with the device orientation itself.

See: Multiple-line-syntax

It also support variables in multiline string, for example:

String name="zzg";
String lines = ""/**~!{
    SELECT * 
        FROM user
        WHERE name="$name"
}*/;
System.out.println(lines);

Output:

SELECT * 
    FROM user
    WHERE name="zzg"

Use the modulo operator:

if wordLength % 2 == 0:
    print "wordLength is even"
else:
    print "wordLength is odd"

For your problem, the simplest is to check if the word is equal to its reversed brother. You can do that with word[::-1], which create the list from word by taking every character from the end to the start:

def is_palindrome(word):
    return word == word[::-1]

Use target-attribute:

<a target="_parent" href="http://url.org">link</a>

Use the .date() method to convert a datetime to a date:

if item_date.date() > from_date:

Alternatively, you could use datetime.today() instead of date.today(). You could use

from_date = from_date.replace(hour=0, minute=0, second=0, microsecond=0)

to eliminate the time part afterwards.

The answer was very funny for me and my team, and worked like a charm

• In the Interface Builder, Just move the tableview under another view in the view hierarchy.

REASON:

We observed that this happens only for the First View in the View Hierarchy, if this first view is a UITableView. So, all other similar UITableViews do not have this annoying section, except the first. We Tried moving the UITableView out of the first place in the view hierarchy, and everything was working as expected.

If you just call exit in Bash without any parameters, it will return the exit code of the last command. Combined with OR, Bash should only invoke exit, if the previous command fails. But I haven't tested this.

command1 || exit;
command2 || exit;

Bash will also store the exit code of the last command in the variable $?.

To test this, I wrote this code, borrowing from the NativeScript Tutorial:

user.ts

export class User {
    email: string;
    password: string;
    lastLogin: Date;

    constructor(msg:string) {        
        this.email = "";
        this.password = "";
        this.lastLogin = new Date();
        console.log("*** User class constructor " + msg + " ***");
    }

    Login() {
    }
}

login.component.ts

import {Component} from "@angular/core";
import {User} from "./../../shared/user/user"

@Component({
  selector: "login-component",
  templateUrl: "pages/login/login.html",
  styleUrls: ["pages/login/login-common.css", "pages/login/login.css"]
})
export class LoginComponent {

  user: User = new User("property");  // ONE
  isLoggingIn:boolean;

  constructor() {    
    this.user = new User("constructor");   // TWO
    console.log("*** Login Component Constructor ***");
  }

  ngOnInit() {
    this.user = new User("ngOnInit");   // THREE
    this.user.Login();
    this.isLoggingIn = true;
    console.log("*** Login Component ngOnInit ***");
  }

  submit() {
    alert("You’re using: " + this.user.email + " " + this.user.lastLogin);
  }

  toggleDisplay() {
    this.isLoggingIn = !this.isLoggingIn;
  }

}

Console output

JS: *** User class constructor property ***  
JS: *** User class constructor constructor ***  
JS: *** Login Component Constructor ***  
JS: *** User class constructor ngOnInit ***  
JS: *** Login Component ngOnInit ***  

As often, guava has what you need.

cur_ques_details is already a JS object, you don't need to parse it

BIT should only allow 0 and 1 (and NULL, if the field is not defined as NOT NULL). TINYINT(1) allows any value that can be stored in a single byte, -128..127 or 0..255 depending on whether or not it's unsigned (the 1 shows that you intend to only use a single digit, but it does not prevent you from storing a larger value).

For versions older than 5.0.3, BIT is interpreted as TINYINT(1), so there's no difference there.

BIT has a "this is a boolean" semantic, and some apps will consider TINYINT(1) the same way (due to the way MySQL used to treat it), so apps may format the column as a check box if they check the type and decide upon a format based on that.

Your question is not 100% clear, but I'm assuming you want to find every piece of text inside [P][/P] tags:

>>> import re
>>> line = "President [P] Barack Obama [/P] met Microsoft founder [P] Bill Gates [/P], yesterday."
>>> re.findall('\[P\]\s?(.+?)\s?\[\/P\]', line)
['Barack Obama', 'Bill Gates']

In terms of entities (or objects) you have a Class object which has a collection of Students and a Student object that has a collection of Classes. Since your StudentClass table only contains the Ids and no extra information, EF does not generate an entity for the joining table. That is the correct behaviour and that's what you expect.

Now, when doing inserts or updates, try to think in terms of objects. E.g. if you want to insert a class with two students, create the Class object, the Student objects, add the students to the class Students collection add the Class object to the context and call SaveChanges:

using (var context = new YourContext())
{
    var mathClass = new Class { Name = "Math" };
    mathClass.Students.Add(new Student { Name = "Alice" });
    mathClass.Students.Add(new Student { Name = "Bob" });

    context.AddToClasses(mathClass);
    context.SaveChanges();
}

This will create an entry in the Class table, two entries in the Student table and two entries in the StudentClass table linking them together.

You basically do the same for updates. Just fetch the data, modify the graph by adding and removing objects from collections, call SaveChanges. Check this similar question for details.

Edit:

According to your comment, you need to insert a new Class and add two existing Students to it:

using (var context = new YourContext())
{
    var mathClass= new Class { Name = "Math" };
    Student student1 = context.Students.FirstOrDefault(s => s.Name == "Alice");
    Student student2 = context.Students.FirstOrDefault(s => s.Name == "Bob");
    mathClass.Students.Add(student1);
    mathClass.Students.Add(student2);

    context.AddToClasses(mathClass);
    context.SaveChanges();
}

Since both students are already in the database, they won't be inserted, but since they are now in the Students collection of the Class, two entries will be inserted into the StudentClass table.

Hi, you need to put this in form activate, and have an id field named id...

this way it passes until it reaches the one without id (AKA new one)...

Branches in SVN are essentially directories; you don't name the branch so much as choose the name of the directory to branch into.

The common way of 'naming' a branch is to place it under a directory called branches in your repository. In the "To URL:" portion of TortoiseSVN's Branch dialog, you would therefore enter something like:

(svn/http)://path-to-repo/branches/your-branch-name

The main branch of a project is referred to as the trunk, and is usually located in:

(svn/http)://path-to-repo/trunk

I think you should read this post by Christian Heilmann. He explains that background images are ONLY for aesthetics and should not be used to present data, and are therefore exempt from the rule that every image should have alternate-text.

Excerpt (emphasis mine):

CSS background images which are by definition only of aesthetic value – not visual content of the document itself. If you need to put an image in the page that has meaning then use an IMG element and give it an alternative text in the alt attribute.

I agree with him.

To disable inputting password:

sudo visudo

Then add a new line like below and save then:

# The user can run installer as root without inputting password
yourusername ALL=(root) NOPASSWD: /usr/sbin/installer

Then you run installer without password:

sudo installer -pkg ...

    ClassLoader cl = ClassLoader.getSystemClassLoader();

    URL[] urls = ((URLClassLoader)cl).getURLs();

    for(URL url: urls){
        System.out.println(url.getFile());
    }

If you want something like : InputString => StringPart1...StringPart2

HTML:

<html ng-app="myApp">
  <body>
    {{ "AngularJS string limit example" | strLimit: 10 : 20 }}

Angular Code:

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

 myApp.filter('strLimit', ['$filter', function($filter) {
   return function(input, beginlimit, endlimit) {
      if (! input) return;
      if (input.length <= beginlimit + endlimit) {
          return input;
      }

      return $filter('limitTo')(input, beginlimit) + '...' + $filter('limitTo')(input, -endlimit) ;
   };
}]);

Example with following parameters :
beginLimit = 10
endLimit = 20

If using Spring's XML schema based configuration, setup in the Spring context like this:

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:jee="http://www.springframework.org/schema/jee" xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd">
...
<jee:jndi-lookup id="dbDataSource"
   jndi-name="jdbc/DatabaseName"
   expected-type="javax.sql.DataSource" />

Alternatively, setup using simple bean configuration like this:

<bean id="DatabaseName" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/DatabaseName"/>
</bean>

You can declare the JNDI resource in tomcat's server.xml using something like this:

<GlobalNamingResources>
    <Resource name="jdbc/DatabaseName"
              auth="Container"
              type="javax.sql.DataSource"
              username="dbUser"
              password="dbPassword"
              url="jdbc:postgresql://localhost/dbname"
              driverClassName="org.postgresql.Driver"
              initialSize="20"
              maxWaitMillis="15000"
              maxTotal="75"
              maxIdle="20"
              maxAge="7200000"
              testOnBorrow="true"
              validationQuery="select 1"
              />
</GlobalNamingResources>

And reference the JNDI resource from Tomcat's web context.xml like this:

  <ResourceLink name="jdbc/DatabaseName"
   global="jdbc/DatabaseName"
   type="javax.sql.DataSource"/>

• Tomcat 8 JNDI Datasource HOW-TO
• Tomcat 8 Context Resource Links Reference

Edit: This answer has been updated for Tomcat 8 and Spring 4. There have been a few property name changes for Tomcat's default datasource resource pool setup.

Check the daemon option in nginx.conf file. It has to be ON. Or you can simply rip out this line from config file. This option is fully described here http://nginx.org/en/docs/ngx_core_module.html#daemon

For Windows, you can go with CutyCapt, which has similar functionality.

Tail-call optimization is where you are able to avoid allocating a new stack frame for a function because the calling function will simply return the value that it gets from the called function. The most common use is tail-recursion, where a recursive function written to take advantage of tail-call optimization can use constant stack space.

Scheme is one of the few programming languages that guarantee in the spec that any implementation must provide this optimization, so here are two examples of the factorial function in Scheme:

(define (fact x)
  (if (= x 0) 1
      (* x (fact (- x 1)))))

(define (fact x)
  (define (fact-tail x accum)
    (if (= x 0) accum
        (fact-tail (- x 1) (* x accum))))
  (fact-tail x 1))

The first function is not tail recursive because when the recursive call is made, the function needs to keep track of the multiplication it needs to do with the result after the call returns. As such, the stack looks as follows:

(fact 3)
(* 3 (fact 2))
(* 3 (* 2 (fact 1)))
(* 3 (* 2 (* 1 (fact 0))))
(* 3 (* 2 (* 1 1)))
(* 3 (* 2 1))
(* 3 2)
6

In contrast, the stack trace for the tail recursive factorial looks as follows:

(fact 3)
(fact-tail 3 1)
(fact-tail 2 3)
(fact-tail 1 6)
(fact-tail 0 6)
6

As you can see, we only need to keep track of the same amount of data for every call to fact-tail because we are simply returning the value we get right through to the top. This means that even if I were to call (fact 1000000), I need only the same amount of space as (fact 3). This is not the case with the non-tail-recursive fact, and as such large values may cause a stack overflow.

Before answering your question:

If you do not have a Person class, first you must consider whether you want to create a Person class. Do you plan to reuse the concept of a Person very often? If so, you should create a Person class. (You have access to this data in the form of a passed-in variable and you don't care about being messy and sloppy.)

To answer your question:

You have access to their birthyear, so in that case you likely have a Person class with a someperson.birthdate field. In that case, you have to ask yourself, is someperson.age a value that is reusable?

The answer is yes. We often care about age more than the birthdate, so if the birthdate is a field, age should definitely be a derived field. (A case where we would not do this: if we were calculating values like someperson.chanceIsFemale or someperson.positionToDisplayInGrid or other irrelevant values, we would not extend the Person class; you just ask yourself, "Would another program care about the fields I am thinking of extending the class with?" The answer to that question will determine if you extend the original class, or make a function (or your own class like PersonAnalysisData or something).)

For the first question I think answer would be:

<your DataFrame>.rename(columns={'count':'Total_Numbers'})

or

<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']

As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:

Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]

Starting from the data.table y, you can just write:
y[, (cols):=lapply(.SD, function(i){i[is.na(i)] <- 0; i}), .SDcols = cols]
Don't forget to library(data.table) before creating y and running this command.

If you have a large number of sequentially named data frames you can create a list of the desired subset of data frames like this:

d1 <- data.frame(y1=c(1,2,3), y2=c(4,5,6))
d2 <- data.frame(y1=c(3,2,1), y2=c(6,5,4))
d3 <- data.frame(y1=c(6,5,4), y2=c(3,2,1))
d4 <- data.frame(y1=c(9,9,9), y2=c(8,8,8))

my.list <- list(d1, d2, d3, d4)
my.list

my.list2 <- lapply(paste('d', seq(2,4,1), sep=''), get)
my.list2

where my.list2 returns a list containing the 2nd, 3rd and 4th data frames.

[[1]]
  y1 y2
1  3  6
2  2  5
3  1  4

[[2]]
  y1 y2
1  6  3
2  5  2
3  4  1

[[3]]
  y1 y2
1  9  8
2  9  8
3  9  8

Note, however, that the data frames in the above list are no longer named. If you want to create a list containing a subset of data frames and want to preserve their names you can try this:

list.function <-  function() { 

     d1 <- data.frame(y1=c(1,2,3), y2=c(4,5,6))
     d2 <- data.frame(y1=c(3,2,1), y2=c(6,5,4))
     d3 <- data.frame(y1=c(6,5,4), y2=c(3,2,1))
     d4 <- data.frame(y1=c(9,9,9), y2=c(8,8,8))

     sapply(paste('d', seq(2,4,1), sep=''), get, environment(), simplify = FALSE) 
} 

my.list3 <- list.function()
my.list3

which returns:

> my.list3
$d2
  y1 y2
1  3  6
2  2  5
3  1  4

$d3
  y1 y2

It's not possible to change web-kit browsers use user's computer or mobiles default date format. But if you can use jquery and jquery UI there is a date-picker which is designable and can be shown in any format as the developer wants. the link to the jquery UI date-picker is on this page http://jqueryui.com/datepicker/ you can find demo as well as code and documentation or documentation link

Edit:-I find that chrome uses language settings that are by default equal to system settings but the user can change them but developer can't force users to do so so you have to use other js solutions like I tell you can search the web with queries like javascript date-pickers or jquery date-picker

WinForm:

private void button1_Click(object sender, EventArgs e)
{
   button2.BackColor = Color.Red;
}

WPF:

private void button1_Click(object sender, RoutedEventArgs e)
{
   button2.Background = Brushes.Blue;
}

Use this : -- SQL Server 2008 or later

This solution works with Swift 4 (Xcode 9.2) and also with Swift 5 (Xcode 10.2.1+):

let fileManager = FileManager.default
let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
do {
    let fileURLs = try fileManager.contentsOfDirectory(at: documentsURL, includingPropertiesForKeys: nil)
    // process files
} catch {
    print("Error while enumerating files \(documentsURL.path): \(error.localizedDescription)")
}

Here's a reusable FileManager extension that also lets you skip or include hidden files in the results:

import Foundation

extension FileManager {
    func urls(for directory: FileManager.SearchPathDirectory, skipsHiddenFiles: Bool = true ) -> [URL]? {
        let documentsURL = urls(for: directory, in: .userDomainMask)[0]
        let fileURLs = try? contentsOfDirectory(at: documentsURL, includingPropertiesForKeys: nil, options: skipsHiddenFiles ? .skipsHiddenFiles : [] )
        return fileURLs
    }
}

// Usage
print(FileManager.default.urls(for: .documentDirectory) ?? "none")

Change the wrapping from "onload" to "No wrap - in <body>"

The function defined has a different scope.

Go to your desired perspective. Go to 'Window->show view' menu.

If you see logcat there, click it and you are done.

Else, click on 'other' (at the bottom), chose 'Android'->logcat.

Hope that helps :-)

MS already made a method for this, so you dont have to use the null coalescing operator. No difference in functionality, but it is easier for non-experts to get what is happening at a glance.

DateTime updatedTime = _objHotelPackageOrder.UpdatedDate.GetValueOrDefault(DateTime.Now);

This variation will clone a remote repo with all branches available locally without having to checkout each branch one by one. No fancy scripts needed.

Make a folder with the same name of the repo you wish to clone and cd into for example:

mkdir somerepo
cd somerepo

Now do these commands but with actual repo usersname/reponame

git clone --bare [email protected]:someuser/somerepo.git .git
git config --bool core.bare false
git reset --hard
git branch

Voiala! you have all the branches there!

Figuring out dependencies for small projects is not hard. But once you start dealing with a dependency tree with hundreds of dependencies, things can easily get out of hand. (I'm speaking from experience here ...)

The other point is that if you use an IDE with incremental compilation and Maven support (like Eclipse + m2eclipse), then you should be able to set up edit/compile/hot deploy and test.

I personally don't do this because I've come to distrust this mode of development due to bad experiences in the past (pre Maven). Perhaps someone can comment on whether this actually works with Eclipse + m2eclipse.

It seems like str_shuffle would be a good use for this. Seed the shuffle with whichever characters you want.

$my_rand_strng = substr(str_shuffle("ABCDEFGHIJKLMNOPQRSTUVWXYZ"), -5);

The error is a stack overflow. That should ring a bell on this site, right? It occurs because a call to poruszanie results in another call to poruszanie, incrementing the recursion depth by 1. The second call results in another call to the same function. That happens over and over again, each time incrementing the recursion depth.

Now, the usable resources of a program are limited. Each function call takes a certain amount of space on top of what is called the stack. If the maximum stack height is reached, you get a stack overflow error.

In your project level Gradle file increase the dependencies classpath version low to high like

dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }

to change like

dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }

In WPF there is a control named Popup.

Popup myPopup = new Popup();
//(...)
myPopup.IsOpen = true;

I liked steamer25's solution as it seems the most robust for my purposes. However, when debugging in RStudio (in windows), the path would not get set properly. The reason being that if a breakpoint is set in RStudio, sourcing the file uses an alternate "debug source" command which sets the script path a little differently. Here is the final version which I am currently using which accounts for this alternate behavior within RStudio when debugging:

# @return full path to this script
get_script_path <- function() {
    cmdArgs = commandArgs(trailingOnly = FALSE)
    needle = "--file="
    match = grep(needle, cmdArgs)
    if (length(match) > 0) {
        # Rscript
        return(normalizePath(sub(needle, "", cmdArgs[match])))
    } else {
        ls_vars = ls(sys.frames()[[1]])
        if ("fileName" %in% ls_vars) {
            # Source'd via RStudio
            return(normalizePath(sys.frames()[[1]]$fileName)) 
        } else {
            # Source'd via R console
            return(normalizePath(sys.frames()[[1]]$ofile))
        }
    }
}

I modified the above function to account for carriage returns in IE. It's untested but I did something similar with it in my code so it should be workable.

function getCaret(el) {
  if (el.selectionStart) { 
    return el.selectionStart; 
  } else if (document.selection) { 
    el.focus(); 

    var r = document.selection.createRange(); 
    if (r == null) { 
      return 0; 
    } 

    var re = el.createTextRange(), 
    rc = re.duplicate(); 
    re.moveToBookmark(r.getBookmark()); 
    rc.setEndPoint('EndToStart', re); 

    var add_newlines = 0;
    for (var i=0; i<rc.text.length; i++) {
      if (rc.text.substr(i, 2) == '\r\n') {
        add_newlines += 2;
        i++;
      }
    }

    //return rc.text.length + add_newlines;

    //We need to substract the no. of lines
    return rc.text.length - add_newlines; 
  }  
  return 0; 
}

@hop5 and @RnMss suggested to use C++11 lambdas, but if you deal with pointers, you can use them directly:

#include <thread>
#include <iostream>

class CFoo {
  public:
    int m_i = 0;
    void bar() {
      ++m_i;
    }
};

int main() {
  CFoo foo;
  std::thread t1(&CFoo::bar, &foo);
  t1.join();
  std::thread t2(&CFoo::bar, &foo);
  t2.join();
  std::cout << foo.m_i << std::endl;
  return 0;
}

outputs

2

Rewritten sample from this answer would be then:

#include <thread>
#include <iostream>

class Wrapper {
  public:
      void member1() {
          std::cout << "i am member1" << std::endl;
      }
      void member2(const char *arg1, unsigned arg2) {
          std::cout << "i am member2 and my first arg is (" << arg1 << ") and second arg is (" << arg2 << ")" << std::endl;
      }
      std::thread member1Thread() {
          return std::thread(&Wrapper::member1, this);
      }
      std::thread member2Thread(const char *arg1, unsigned arg2) {
          return std::thread(&Wrapper::member2, this, arg1, arg2);
      }
};

int main() {
  Wrapper *w = new Wrapper();
  std::thread tw1 = w->member1Thread();
  tw1.join();
  std::thread tw2 = w->member2Thread("hello", 100);
  tw2.join();
  return 0;
}

SET TERMOUT

SET TERMOUT OFF suppresses the display so that you can spool output from a script without seeing it on the screen.

If both spooling to file and writing to terminal are not required, use SET TERMOUT OFF in >SQL scripts to disable terminal output.

SET TERMOUT is not supported in iSQL*Plus

"Hard Coding" means something that you want to embeded with your program or any project that can not be changed directly. For example if you are using a database server, then you must hardcode to connect your database with your project and that can not be changed by user. Because you have hard coded.

You can use ffprobe to get frame number with the following commands

1. first method

ffprobe.exe -i video_name -print_format json -loglevel fatal -show_streams -count_frames -select_streams v

which tell to print data in json format

select_streams v will tell ffprobe to just give us video stream data and if you remove it, it will give you audio information as well

and the output will be like

            }
        }
    ]
}

2. you can use

ffprobe -v error -show_format -show_streams video_name

which will give you stream data, if you want selected information like frame rate, use the following command

ffprobe -v error -select_streams v:0 -show_entries stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1 video_name

which give a number base on your video information, the problem is when you use this method, its possible you get a N/A as output.

for more information check this page FFProbe Tips

if you use this way :

dir, err := filepath.Abs(filepath.Dir(os.Args[0]))
if err != nil {
    log.Fatal(err)
}
fmt.Println(dir)

you will get the /tmp path when you are running program using some IDE like GoLang because the executable will save and run from /tmp

i think the best way for getting the currentWorking Directory or '.' is :

import(
  "os" 
  "fmt"
  "log"
)

func main() {
  dir, err := os.Getwd()
    if err != nil {
        log.Fatal(err)
    }
  fmt.Println(dir)
}

the os.Getwd() function will return the current working directory. and its all without using of any external library :D

It's not a big deal on a small/personal scale, but it can become a bigger deal quickly on a larger scale. My employer is a large Microsoft shop, but won't/can't buy into Team System/TFS for a number of reasons. We currently use Subversion + Orcas + MBUnit + TestDriven.NET and it works well, but getting TD.NET was a huge hassle. The version sensitivity of MBUnit + TestDriven.NET is also a big hassle, and having one additional commercial thing (TD.NET) for legal to review and procurement to handle and manage, isn't trivial. My company, like a lot of companies, are fat and happy with a MSDN Subscription model, and it's just not used to handling one off procurements for hundreds of developers. In other words, the fully integrated MS offer, while definitely not always best-of-bread, is a significant value-add in my opinion.

I think we'll stay with our current step because it works and we've already gotten over the hump organizationally, but I sure do wish MS had a compelling offering in this space so we could consolidate and simplify our dev stack a bit.

I tried the solutions above, but sometimes you just gotta do it yourself. Might be off by a pixel in some cases but works fine in general.

import matplotlib.pyplot as plt

    n_slices = np.sqrt(number_of_tiles)
    assert int(n_slices + 0.5) ** 2 == number_of_tiles, "Number of tiles is not a perfect square"

    n_slices = n_slices.astype(np.int)
    [w, h] = cropped_npy.shape

    return tiles

Hope it helps.

You can use a native Filter Validator

filter_var($url, FILTER_VALIDATE_URL);

Validates value as URL (according to » http://www.faqs.org/rfcs/rfc2396), optionally with required components. Beware a valid URL may not specify the HTTP protocol http:// so further validation may be required to determine the URL uses an expected protocol, e.g. ssh:// or mailto:. Note that the function will only find ASCII URLs to be valid; internationalized domain names (containing non-ASCII characters) will fail.

Example:

if (filter_var($url, FILTER_VALIDATE_URL) === FALSE) {
    die('Not a valid URL');
}

The way to do this is to set the EnableHeadersVisualStyles flag for the data grid view to False, and set the background colour via the ColumnHeadersDefaultCellStyle.BackColor property. For example, to set the background colour to blue, use the following (or set in the designer if you prefer):

_dataGridView.ColumnHeadersDefaultCellStyle.BackColor = Color.Blue;
_dataGridView.EnableHeadersVisualStyles = false;

If you do not set the EnableHeadersVisualStyles flag to False, then the changes you make to the style of the header will not take effect, as the grid will use the style from the current users default theme. The MSDN documentation for this property is here.

The comparison needs to be evaluated fully inside EL ${ ... }, not outside.

<c:if test="${values.type eq 'object'}">

As to the docs, those ${} things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.

<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

See also:

• Our EL wiki page

By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass() and then Class#getSimpleName() instead of adding a custom getter.

<c:forEach items="${list}" var="value">
    <c:if test="${value['class'].simpleName eq 'Object'}">
        <!-- code here -->
    </c:if>
</c:forEeach>

You have to first clear the table and then add new data using row.add() function. At last step adjust also column size so that table renders correctly.

$('#upload-new-data').on('click', function () {
   datatable.clear().draw();
   datatable.rows.add(NewlyCreatedData); // Add new data
   datatable.columns.adjust().draw(); // Redraw the DataTable
});

Also if you want to find a mapping between old and new datatable API functions bookmark this

I resolved this by just running a simple:

git pull

Nothing more. Now it's showing:

# On branch master
nothing to commit, working directory clean

The line

$location.absUrl() == 'http://www.google.com';

is wrong. First == makes a comparison, and what you are probably trying to do is an assignment, which is with simple = and not double ==.

And because absUrl() getter only. You can use url(), which can be used as a setter or as a getter if you want.

reference : http://docs.angularjs.org/api/ng.$location

Background color of views (navigator, console, tasks etc) is set according to the desktop (system) settings. On Linux/GNome I changed System/Preferences/Appeareance to change this color.

Editor colors are set chaotically by different editors, search for background in eclipse preferences to find different options. One easy way to get beautiful dark (and not only dark) themes is to install Afae plugin, and then pick theme within its preferences (twilight theme is beautiful, for example) - again, eclipse prefs, Afae group. Of course this applies only when you edit with Afae.

print didn't transition from statement to function until Python 3.0. If you're using older Python then you can suppress the newline with a trailing comma like so:

print "Foo %10s bar" % baz,

mutil init function in one package execute order:

1. const and variable defined file init() function execute

With SQL Developer 4.x, the language option is to be added to ..\sqldeveloper\bin\sqldeveloper.conf, rather than ..\sqldeveloper\bin\ide.conf:

# ----- MODIFICATION BEGIN -----
AddVMOption -Duser.language=en
# ----- MODIFICATION END -----

var obj = [
  {"name": "Afghanistan", "code": "AF"}, 
  {"name": "Åland Islands", "code": "AX"}, 
  {"name": "Albania", "code": "AL"}, 
  {"name": "Algeria", "code": "DZ"}
];

// the code you're looking for
var needle = 'AL';

// iterate over each element in the array
for (var i = 0; i < obj.length; i++){
  // look for the entry with a matching `code` value
  if (obj[i].code == needle){
     // we found it
    // obj[i].name is the matched result
  }
}

if you want to use hex code of color which is in this format #123456 then it is very easily be used, create A variables of type Color and assign the following values to it.

Color myHexColor = Color(0xff123456) 

// her you notice I use the 0xff and that is opacity or transparency of the color 
// and you can also change these value .

use myhexcolor and you are ready to go .

if you want to change the opacity of color direct from the hex code then change the ff value in 0xff to the respectively value from the table below.

Hex Opacity Values

100% — FF

95% — F2

90% — E6

85% — D9

80% — CC

75% — BF

70% — B3

65% — A6

60% — 99

You can remove database directly as:

$ mysqladmin -h [host] -u [user] -p drop [database_name]

[Enter Password]

Do you really want to drop the 'hairfree' database [y/N]: y

Using std::string:

#include <string>

std::string result = std::string(one) + std::string(two);

This question is really old, but I came across this page when I was looking for the easiest and quickest way to do this. Using Webpack is much simpler:

install webpack-dev-server

npm i -g webpack-dev-server

start webpack-dev-server with https

webpack-dev-server --https

If you want to check all of your input matches,

>>> all(x in ['b', 'a', 'foo', 'bar'] for x in ['a', 'b'])

if you want to check at least one match,

>>> any(x in ['b', 'a', 'foo', 'bar'] for x in ['a', 'b'])

You have a few different options:

• you can use a SPA router like SammyJS, or Angularjs and ui-router, so your pages are stateful.
• use sessionStorage to store your state.
• store the values on the URL hash.

Here is what sudo apt-get purge ruby* removed relating to GRUB for me:

grub-pc 
grub-gfxpayload-lists
grub2-common
grub-pc-bin 
grub-common 

Try the following:

var filteredFileSet = fileList.Where(item => filterList.Contains(item));

When you iterate over filteredFileSet (See LINQ Execution) it will consist of a set of IEnumberable values. This is based on the Where Operator checking to ensure that items within the fileList data set are contained within the filterList set.

As fileList is an IEnumerable set of string values, you can pass the 'item' value directly into the Contains method.

I am not sure about your DBMS. So, I created a temporary table in Redshift and from my experience, I think this query should return what you are looking for:

select min(Id), distinct MailId, EmailAddress, Name
    from yourTableName
    group by MailId, EmailAddress, Name

I see that I am using a GROUP BY clause but you still won't have two rows against any particular MailId.

Try this code

SELECT CONVERT(varchar(max), CAST(1000.2324422 AS decimal(11,2)))

result:1000.23

here decimal(11,2):11-total digits count(without point),2-for two digits after decimal point

col-md-offset-4 does not work if you manually apply margin to the same element. For example

In the above code, offset will not be applied. Instead a margin of 0 auto will be applied

In addition to the answers above, the following worked for me : -

Scenario -

1. I pushed my_branch to origin successfully.
2. I made few more changes.
3. When I tried to push again, (after doing add, commit of course), I got the above mentioned error.

Solution -

 1. git checkout **my_branch**
 2. git add, commit your changes.
 3. git pull origin **my_branch** (not origin, master, or develop)
 4. git push origin **my_branch**

After looking for an answer for the question for months, I finally find a really best solution: writing a simple script.

#!/usr/bin/expect

set timeout 20

set cmd [lrange $argv 1 end]
set password [lindex $argv 0]

eval spawn $cmd
expect "assword:"   # matches both 'Password' and 'password'
send "$password\r";
interact

Put it to /usr/bin/exp, then you can use:

• exp <password> ssh <anything>
• exp <password> scp <anysrc> <anydst>

Done!

I was looking for this same answer and I couldn't find anything that did exactly what I wanted so I created my own and posted it here:

http://seekieran.com/2011/03/jquery-scrolling-box/

Working Demo: http://jsbin.com/azoji3

Here is the important code:

function ScrollDown(){

  //var topVal = $('.up').parents(".container").find(".content").css("top").replace(/[^-\d\.]/g, '');
  var topVal = $(".content").css("top").replace(/[^-\d\.]/g, '');
    topVal = parseInt(topVal);
  console.log($(".content").height()+ " " + topVal);
  if(Math.abs(topVal) < ($(".content").height() - $(".container").height() + 60)){ //This is to limit the bottom of the scrolling - add extra to compensate for issues
  $('.up').parents(".container").find(".content").stop().animate({"top":topVal - 20  + 'px'},'slow');
    if (mouseisdown)
setTimeout(ScrollDown, 400);
  }

Recursion to make it happen:

 $('.dn').mousedown(function(event) {
    mouseisdown = true;
    ScrollDown();
}).mouseup(function(event) {
    mouseisdown = false;
});

Thanks to Jonathan Sampson for some code to start but it didn't work initially so I have heavily modified it. Any suggestions to improve it would be great here in either the comments or comments on the blog.

Goyuix's solution works great, but as presented it gives me this error: "The requested FTP command is not supported when using HTTP proxy."

Adding this line after $ftp.UsePassive = $true fixed the problem for me:

$ftp.Proxy = $null;

Its work for me - you can try this

dataTable({
    "paging":   true,
    "ordering": false,
    "info":     true,
})

The necessary variable is inventory_hostname.

- name: Install this only for local dev machine
  pip: name=pyramid
  when: inventory_hostname == "local"

It is somewhat hidden in the documentation at the bottom of this section.

If you have a list of lists, you only needed to use ...

import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)

per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.

You can also use array_reduce

array_reduce — Iteratively reduce the array to a single value using a callback function

example:

$tbody = array_reduce($rows, function($a, $b){return $a.="<tr><td>".implode("</td><td>",$b)."</td></tr>";});
$thead = "<tr><th>" . implode("</th><th>", array_keys($rows[0])) . "</th></tr>";

echo "<table>\n$thead\n$tbody\n</table>";

Try this way:

<%= f.select(:object_field, ['Item 1', ...], {}, { :class => 'my_style_class' }) %>

select helper takes two options hashes, one for select, and the second for html options. So all you need is to give default empty options as first param after list of items and then add your class to html_options.

http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#method-i-select

In pandoc, if you use the option --toc in producing html, a table of contents will be produced with links to the sections, and back to the table of contents from the section headings. It is similar with the other formats pandoc writes, like LaTeX, rtf, rst, etc. So with the command

pandoc --toc happiness.txt -o happiness.html

this bit of markdown:

        }

 System.out.println("Triangle c");

          for( line = 1; line <= 10; line++ )
        {
            for( star = 1; star <= 10; star++ )
            {

        if(line<=star)
                System.out.print( "*" );
                //else
                 // System.out.print(" ");
            }
            System.out.println();
        }

 System.out.println("Triangle d");

          for( line = 1; line <= 10; line++ )
        {
            for( star = 1; star <= 10; star++ )
            {

        if(line>10-star)
                System.out.print( "*" );
                else
                  System.out.print(" ");
            }
            System.out.println();
        }

A rather simple solution is to create a singleton manager class, in which you can store a reference to one or more Activities, or anything else you want access to throughout the app.

Call UberManager.getInstance().setMainActivity( activity ); in the main activity's onCreate.

Call UberManager.getInstance().getMainActivity(); anywhere in your app to retrieve it. (I am using this to be able to use Toast from a non UI thread.)

Make sure you add a call to UberManager.getInstance().cleanup(); when your app is being destroyed.

import android.app.Activity;

public class UberManager
{
    private static UberManager instance = new UberManager();

    private Activity mainActivity = null;

    private UberManager()
    {

    }

    public static UberManager getInstance()
    {
        return instance;
    }

    public void setMainActivity( Activity mainActivity )
    {
        this.mainActivity = mainActivity;
    }

    public Activity getMainActivity()
    {
        return mainActivity;
    }

    public void cleanup()
    {
        mainActivity = null;
    }
}

Don't like any of those solutions.

this is how i do it:

$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='" 
            . sqlEsc($somename) . "' ;";

then i use my own sqlEsc function:

function sqlEsc($val) 
{
    global $mysqli;
    return mysqli_real_escape_string($mysqli, $val);
}

I created multiple threads in Python, I printed the thread objects, and I printed the id using the ident variable. I see all the ids are same:

<Thread(Thread-1, stopped 140500807628544)>
<Thread(Thread-2, started 140500807628544)>
<Thread(Thread-3, started 140500807628544)>

Just do this:

String strLong = Long.toString(longNumber);

if none of the above is working you can use this->

idAssignedToEntryWidget.delete(first = 0, last = UpperLimitAssignedToEntryWidget)

for e.g. ->

id assigned is = en then

en.delete(first =0, last =100)

Summary

Simply prevent the default browser action:

window.addEventListener("keydown", function(e) {
    // space and arrow keys
    if([32, 37, 38, 39, 40].indexOf(e.code) > -1) {
        e.preventDefault();
    }
}, false);

If you need to support Internet Explorer or other older browsers, use e.keyCode instead of e.code, but keep in mind that keyCode is deprecated.

Original answer

I used the following function in my own game:

var keys = {};
window.addEventListener("keydown",
    function(e){
        keys[e.code] = true;
        switch(e.code){
            case 37: case 39: case 38:  case 40: // Arrow keys
            case 32: e.preventDefault(); break; // Space
            default: break; // do not block other keys
        }
    },
false);
window.addEventListener('keyup',
    function(e){
        keys[e.code] = false;
    },
false);

The magic happens in e.preventDefault();. This will block the default action of the event, in this case moving the viewpoint of the browser.

If you don't need the current button states you can simply drop keys and just discard the default action on the arrow keys:

var arrow_keys_handler = function(e) {
    switch(e.code){
        case 37: case 39: case 38:  case 40: // Arrow keys
        case 32: e.preventDefault(); break; // Space
        default: break; // do not block other keys
    }
};
window.addEventListener("keydown", arrow_keys_handler, false);

Note that this approach also enables you to remove the event handler later if you need to re-enable arrow key scrolling:

window.removeEventListener("keydown", arrow_keys_handler, false);

add plt.figure(figsize=(16,5)) before the sns.heatmap and play around with the figsize numbers till you get the desired size

...

plt.figure(figsize = (16,5))

ax = sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5)

I think you want something like this:

Intent foo = new Intent(this, viewContacts.class);
foo.putExtra("myFirstKey", "myFirstValue");
foo.putExtra("mySecondKey", "mySecondValue");
startActivity(foo);

or you can combine them into a bundle first. Corresponding getExtra() routines exist for the other side. See the intent topic in the dev guide for more information.

Acutally, it gives several examples of compile commands used for pthreads codes are listed in the table below, if you continue reading the following tutorial:

Suppose your function enters data in columns A and B and you want to a custom Userform to appear if the user selects a cell in column C. One way to do this is to use the SelectionChange event:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Dim clickRng As Range
    Dim lastRow As Long

    lastRow = Range("A1").End(xlDown).Row
    Set clickRng = Range("C1:C" & lastRow) //Dynamically set cells that can be clicked based on data in column A

    If Not Intersect(Target, clickRng) Is Nothing Then
        MyUserForm.Show //Launch custom userform
    End If

End Sub

Note that the userform will appear when a user selects any cell in Column C and you might want to populate each cell in Column C with something like "select cell to launch form" to make it obvious that the user needs to perform an action (having a button naturally suggests that it should be clicked)

Another trick to get the link color working correctly inside the <button> markup

<button type="button" class="btn btn-outline-success and-all-other-classes"> 
  <a href="#" style="color:inherit"> Button text with correct colors </a>
</button>

Please keep in mind that in bs4 beta e.g. btn-primary-outline changed to btn-outline-primary

Just piling on... similar to Feiyu Zhou's post. Here I'm adding the machine name.

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
          .ConfigureAppConfiguration((context, builder) =>
          {
            var env = context.HostingEnvironment;
            var hostname = Environment.MachineName;
            builder.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
              .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true, reloadOnChange: true)
              .AddJsonFile($"appsettings.{hostname}.json", optional: true, reloadOnChange: true);
            builder.AddEnvironmentVariables();
            if (args != null)
            {
              builder.AddCommandLine(args);
            }
          })
        .UseStartup<Startup>();
  }

First, you should disable selinux, edit file /etc/sysconfig/selinux so it looks like this:

SELINUX=disabled
SELINUXTYPE=targeted

Save file and restart system.

Then you can add the new rule to iptables:

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

and restart iptables with /etc/init.d/iptables restart

If it doesn't work you should check other network settings.

If you're open to using jQuery:

<script type="text/javascript">
 function fncsave()
 {
    $('#<%= savebtn.ClientID %>').click();
 }
</script>

Also, if you are using .NET 4 or better you can make the ClientIDMode == static and simplify the code:

<script type="text/javascript">
 function fncsave()
 {
    $("#savebtn").click();
 }
</script>

There is another way of enabling this,

1. use hadoop hdfs -copyFromLocal to copy the .csv data file from your local computer to somewhere in HDFS, say '/path/filename'

2. enter Hive console, run the following script to load from the file to make it as a Hive table. Note that '\054' is the ascii code of 'comma' in octal number, representing fields delimiter.

CREATE EXTERNAL TABLE table name (foo INT, bar STRING)
 COMMENT 'from csv file'
 ROW FORMAT DELIMITED FIELDS TERMINATED BY '\054'
 STORED AS TEXTFILE
 LOCATION '/path/filename';

A PIL only solution for creating a bi-level (black and white) image with a custom threshold:

from PIL import Image
img = Image.open('mB96s.png')
thresh = 200
fn = lambda x : 255 if x > thresh else 0
r = img.convert('L').point(fn, mode='1')
r.save('foo.png')

With just

r = img.convert('1')
r.save('foo.png')

you get a dithered image.

From left to right the input image, the black and white conversion result and the dithered result:

You can click on the images to view the unscaled versions.

This is the command that works for me:

pip list | awk '{print $1}' | xargs pip uninstall -y

I would have put this in a comment on the accepted answer, since that's where it belongs, but I can't. So, just in case anyone gets unreliable results, this could be why.

Be careful of the accepted answer, it fails if the time_point is before the epoch.

This line of code:

std::size_t fractional_seconds = ms.count() % 1000;

will yield unexpected values if ms.count() is negative (since size_t is not meant to hold negative values).

With C99 the %j length modifier can also be used with the printf family of functions to print values of type int64_t and uint64_t:

#include <stdio.h>
#include <stdint.h>

int main(int argc, char *argv[])
{
    int64_t  a = 1LL << 63;
    uint64_t b = 1ULL << 63;

    printf("a=%jd (0x%jx)\n", a, a);
    printf("b=%ju (0x%jx)\n", b, b);

    return 0;
}

Compiling this code with gcc -Wall -pedantic -std=c99 produces no warnings, and the program prints the expected output:

a=-9223372036854775808 (0x8000000000000000)
b=9223372036854775808 (0x8000000000000000)

This is according to printf(3) on my Linux system (the man page specifically says that j is used to indicate a conversion to an intmax_t or uintmax_t; in my stdint.h, both int64_t and intmax_t are typedef'd in exactly the same way, and similarly for uint64_t). I'm not sure if this is perfectly portable to other systems.

qsort() is the function you're looking for. You call it with a pointer to your array of data, the number of elements in that array, the size of each element and a comparison function.

It does its magic and your array is sorted in-place. An example follows:

#include <stdio.h>
#include <stdlib.h>
int comp (const void * elem1, const void * elem2) 
{
    int f = *((int*)elem1);
    int s = *((int*)elem2);
    if (f > s) return  1;
    if (f < s) return -1;
    return 0;
}
int main(int argc, char* argv[]) 
{
    int x[] = {4,5,2,3,1,0,9,8,6,7};

    qsort (x, sizeof(x)/sizeof(*x), sizeof(*x), comp);

    for (int i = 0 ; i < 10 ; i++)
        printf ("%d ", x[i]);

    return 0;
}

== does a numeric comparison: it converts both arguments to a number and then compares them. As long as $str1 and $str2 both evaluate to 0 as numbers, the condition will be satisfied.

eq does a string comparison: the two arguments must match lexically (case-sensitive) for the condition to be satisfied.

"foo" == "bar";   # True, both strings evaluate to 0.
"foo" eq "bar";   # False, the strings are not equivalent.
"Foo" eq "foo";   # False, the F characters are different cases.
"foo" eq "foo";   # True, both strings match exactly.

If you just want a field won't get persisted, both transient and @Transient work. But the question is why @Transient since transient already exists.

Because @Transient field will still get serialized!

Suppose you create a entity, doing some CPU-consuming calculation to get a result and this result will not save in database. But you want to sent the entity to other Java applications to use by JMS, then you should use @Transient, not the JavaSE keyword transient. So the receivers running on other VMs can save their time to re-calculate again.

Just to make someone's life easier, the linq query with lambda expression

(from x in Items where x.Id == 123 select x).FirstOrDefault();

does result in an SQL query with a select top (1) in it.

The first question you need to ask is whether you really need the ID to be random. Sometime, sequential IDs are good enough.

Now, if you do need it to be random, we first note a generated sequence of numbers that contain no duplicates can not be called random. :p Now that we get that out of the way, the fastest way to do this is to have a Hashtable or HashMap containing all the IDs already generated. Whenever a new ID is generated, check it against the hashtable, re-generate if the ID already occurs. This will generally work well if the number of students is much less than the range of the IDs. If not, you're in deeper trouble as the probability of needing to regenerate an ID increases, P(generate new ID) = number_of_id_already_generated / number_of_all_possible_ids. In this case, check back the first paragraph (do you need the ID to be random?).

Hope this helps.

typedef enum {
    ERR_CODE_OK = 0,
    ERR_CODE_SNAP,

    ERR_CODE_NUM
} ERR_CODE;

const char* g_err_msg[ERR_CODE_NUM] = {
    /* ERR_CODE_OK   */ "OK",
    /* ERR_CODE_SNAP */ "Oh, snap!",
};

Above is my simple solution. One benefit of it is the 'NUM' which controls the size of the message array, it also prevents out of boundary access (if you use it wisely).

You can also define a function to get the string:

const char* get_err_msg(ERR_CODE code) {
    return g_err_msg[code];
}

Further to my solution, I then found the following one quite interesting. It generally solved the sync problem of the above one.

It depends on how often you insert or read. You can increase the array by more than one if needed.

numberOfItems = ??

' ...

If numberOfItems+1 >= arr.Length Then
    Array.Resize(arr, arr.Length + 10)
End If

arr(numberOfItems) = newItem
numberOfItems += 1

Also for A, you only need to get the array if needed.

Dim list As List(Of Integer)(arr) ' Do this only once, keep a reference to the list
                                  ' If you create a new List everything you add an item then this will never be fast

'...

list.Add(newItem)
arrayWasModified = True

' ...

Function GetArray()

    If arrayWasModified Then
        arr = list.ToArray()
    End If

    Return Arr
End Function

If you have the time, I suggest you convert it all to List and remove arrays.

JSON doesn't require you to do that, it allows you to do that. It also allows you to use "\u0061" for "A", but it's not required. Allowing \/ helps when embedding JSON in a <script> tag, which doesn't allow </ inside strings, like Seb points out.

Some of Microsoft's ASP.NET Ajax/JSON API's use this loophole to add extra information, e.g., a datetime will be sent as "\/Date(milliseconds)\/". (Yuck)

The mPDF docs state that the first argument of Output() is the file path, second is the saving mode - you need to set it to 'F'.

$mpdf->Output('filename.pdf','F');

Hashing:

It is a one-way algorithm and once hashed can not rollback and this is its sweet point against encryption.

Encryption

If we perform encryption, there will a key to do this. If this key will be leaked all of your passwords could be decrypted easily.

On the other hand, even if your database will be hacked or your server admin took data from DB and you used hashed passwords, the hacker will not able to break these hashed passwords. This would actually practically impossible if we use hashing with proper salt and additional security with PBKDF2.

If you want to take a look at how should you write your hash functions, you can visit here.

There are many algorithms to perform hashing.

1. MD5 - Uses the Message Digest Algorithm 5 (MD5) hash function. The output hash is 128 bits in length. The MD5 algorithm was designed by Ron Rivest in the early 1990s and is not a preferred option today.

2. SHA1 - Uses Security Hash Algorithm (SHA1) hash published in 1995. The output hash is 160 bits in length. Although most widely used, this is not a preferred option today.

3. HMACSHA256, HMACSHA384, HMACSHA512 - Use the functions SHA-256, SHA-384, and SHA-512 of the SHA-2 family. SHA-2 was published in 2001. The output hash lengths are 256, 384, and 512 bits, respectively,as the hash functions’ names indicate.

To convert an object to a byte array:

// Convert an object to a byte array
public static byte[] ObjectToByteArray(Object obj)
{
    BinaryFormatter bf = new BinaryFormatter();
    using (var ms = new MemoryStream())
    {
        bf.Serialize(ms, obj);
        return ms.ToArray();
    }
}

You just need copy this function to your code and send to it the object that you need to convert to a byte array. If you need convert the byte array to an object again you can use the function below:

// Convert a byte array to an Object
public static Object ByteArrayToObject(byte[] arrBytes)
{
    using (var memStream = new MemoryStream())
    {
        var binForm = new BinaryFormatter();
        memStream.Write(arrBytes, 0, arrBytes.Length);
        memStream.Seek(0, SeekOrigin.Begin);
        var obj = binForm.Deserialize(memStream);
        return obj;
    }
}

You can use these functions with custom classes. You just need add the [Serializable] attribute in your class to enable serialization

In my case I had to compare two Integers for equality where both of them could be null. Searched similar topic, didn't found anything elegant for this. Came up with a simple utility functions.

public static boolean integersEqual(Integer i1, Integer i2) {
    if (i1 == null && i2 == null) {
        return true;
    }
    if (i1 == null && i2 != null) {
        return false;
    }
    if (i1 != null && i2 == null) {
        return false;
    }
    return i1.intValue() == i2.intValue();
}

//considering null is less than not-null
public static int integersCompare(Integer i1, Integer i2) {
    if (i1 == null && i2 == null) {
        return 0;
    }
    if (i1 == null && i2 != null) {
        return -1;
    }
    return i1.compareTo(i2);
}

Another elegant solution is to get only what you need, not import all the lodash

import {forEach,merge} from "lodash";

and then use it in your code

forEach({'a':2,'b':3}, (v,k) => {
   console.log(k);
})

While you can't inform JavaScript the language about types, you can inform your IDE about them, so you get much more useful autocompletion.

Here are two ways to do that:

1. Use JSDoc, a system for documenting JavaScript code in comments. In particular, you'll need the @param directive:

   /**
    * @param {Date} myDate - The date
    * @param {string} myString - The string
    */
   function myFunction(myDate, myString) {
     // ...
   }
   

   You can also use JSDoc to define custom types and specify those in @param directives, but note that JSDoc won't do any type checking; it's only a documentation tool. To check types defined in JSDoc, look into TypeScript, which can parse JSDoc tags.

2. Use type hinting by specifying the type right before the parameter in a
   /* comment */:

   

   This is a pretty widespread technique, used by ReactJS for instance. Very handy for parameters of callbacks passed to 3rd party libraries.

TypeScript

For actual type checking, the closest solution is to use TypeScript, a (mostly) superset of JavaScript. Here's TypeScript in 5 minutes.

Try perl -MCPAN -e "upgrade /(.\*)/". It works fine for me.

"FirstLine" + "<br/>" "SecondLine"

The difference appears when the special parameters are quoted. Let me illustrate the differences:

$ set -- "arg  1" "arg  2" "arg  3"

$ for word in $*; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in $@; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in "$*"; do echo "$word"; done
arg  1 arg  2 arg  3

$ for word in "$@"; do echo "$word"; done
arg  1
arg  2
arg  3

one further example on the importance of quoting: note there are 2 spaces between "arg" and the number, but if I fail to quote $word:

$ for word in "$@"; do echo $word; done
arg 1
arg 2
arg 3

and in bash, "$@" is the "default" list to iterate over:

$ for word; do echo "$word"; done
arg  1
arg  2
arg  3

Update for Bootstrap 5 (2020)

Bootstrap 5 (currently alpha) has a new xxl breakpoint. Therefore display classes have a new tier to support this:

Hidden only on xxl: d-xxl-none
Visible only on xxl: d-none d-xxl-block

Bootstrap 4 (2018)

The hidden-* and visible-* classes no longer exist in Bootstrap 4. If you want to hide an element on specific tiers or breakpoints in Bootstrap 4, use the d-* display classes accordingly.

Remember that extra-small/mobile (formerly xs) is the default (implied) breakpoint, unless overridden by a larger breakpoint. Therefore, the -xs infix no longer exists in Bootstrap 4.

Show/hide for breakpoint and down:

• hidden-xs-down (hidden-xs) = d-none d-sm-block
• hidden-sm-down (hidden-sm hidden-xs) = d-none d-md-block
• hidden-md-down (hidden-md hidden-sm hidden-xs) = d-none d-lg-block
• hidden-lg-down = d-none d-xl-block
• hidden-xl-down (n/a 3.x) = d-none (same as hidden)

Show/hide for breakpoint and up:

• hidden-xs-up = d-none (same as hidden)
• hidden-sm-up = d-sm-none
• hidden-md-up = d-md-none
• hidden-lg-up = d-lg-none
• hidden-xl-up (n/a 3.x) = d-xl-none

Show/hide only for a single breakpoint:

• hidden-xs (only) = d-none d-sm-block (same as hidden-xs-down)
• hidden-sm (only) = d-block d-sm-none d-md-block
• hidden-md (only) = d-block d-md-none d-lg-block
• hidden-lg (only) = d-block d-lg-none d-xl-block
• hidden-xl (n/a 3.x) = d-block d-xl-none
• visible-xs (only) = d-block d-sm-none
• visible-sm (only) = d-none d-sm-block d-md-none
• visible-md (only) = d-none d-md-block d-lg-none

Also, note that d-*-block can be replaced with d-*-inline, d-*-flex, d-*-table-cell, d-*-table etc.. depending on the display type of the element. Read more on the display classes

If you want the original URL just use the method as described by jthalborn. If you want to rebuild the url do like David Levesque explained, here is a code snippet for it:

final javax.servlet.http.HttpServletRequest req = (javax.servlet.http.HttpServletRequest) ...;
final int serverPort = req.getServerPort();
if ((serverPort == 80) || (serverPort == 443)) {
  // No need to add the server port for standard HTTP and HTTPS ports, the scheme will help determine it.
  url = String.format("%s://%s/...", req.getScheme(), req.getServerName(), ...);
} else {
  url = String.format("%s://%s:%s...", req.getScheme(), req.getServerName(), serverPort, ...);
}

You still need to consider the case of a reverse-proxy:

• request.getScheme() is returning http instead of returning https in java

Could use constants for the ports but not sure if there is a reliable source for them, default ports:

• Are HTTP and HTTPS default port numbers defined in the JDK?

Most developers will know about port 80 and 443 anyways, so constants are not that helpful.

Other answers are correct -- whether a character is invisible or not depends on what font you use. This seems to be a pretty good list to me of characters that are truly invisible (not even space). It contains some chars that the other lists are missing.

            '\u2060', // Word Joiner
            '\u2061', // FUNCTION APPLICATION

In Angular v10.x and rxjs v6.x

First import map top of my service,

import {map} from 'rxjs/operators';

Then I use map like this

return this.http.get<return type>(URL)
  .pipe(map(x => {
    // here return your pattern
    return x.foo;
  }));

To access helpers from your own controllers, just use:

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

This should help you start your mongod server with custom path and port.

Try to use response.json():

fetch('http://example.com/api/node', {
  mode: "no-cors",
  method: "GET",
  headers: {
    "Accept": "application/json"
  }
}).then((response) => {
  console.log(response.json()); // null
  return dispatch({
    type: "GET_CALL",
    response: response.json()
  });
})
.catch(error => { console.log('request failed', error); });

Assuming "current version" is the working directory (uncommitted modifications) and "last version" is HEAD (last committed modifications for the current branch), simply do

git diff HEAD

Credit for the following goes to user Cerran.

And if you always skip the staging area with -a when you commit, then you can simply use git diff.

Summary

1. git diff shows unstaged changes.
2. git diff --cached shows staged changes.
3. git diff HEAD shows all changes (both staged and unstaged).

jus do this import { shallow, mount } from "enzyme";

const store = mockStore({
  startup: { complete: false }
});

describe("==== Testing App ======", () => {
  const setUpFn = props => {
    return mount(
      <Provider store={store}>
        <App />
      </Provider>
    );
  };

  let wrapper;
  beforeEach(() => {
    wrapper = setUpFn();
  });

We encountered this error today. This is how we debugged and fixed it.

1. Package went to invalid state due to this error ORA-01775.

2. With the error line number , We went thru the package body code and found the code which was trying to insert data into a table.

3. We ran below queries to check if the above table and synonym exists.

   SELECT * FROM DBA_TABLES WHERE TABLE_NAME = '&TABLE_NAME';  -- No rows returned
   
   SELECT * FROM DBA_SYNONYMS WHERE SYNONYM_NAME = '&SYNONYM_NAME'; -- 1 row returned
   

4. With this we concluded that the table needs to be re- created. As the synonym was pointing to a table that did not exist.

5. DBA team re-created the table and this fixed the issue.

Strictly speaking, you should put something that makes sense - according to the spec here, the most correct version is:

<input name=name id=id type=checkbox checked=checked>

For HTML, you can also use the empty attribute syntax, checked="", or even simply checked (for stricter XHTML, this is not supported).

Effectively, however, most browsers will support just about any value between the quotes. All of the following will be checked:

<input name=name id=id type=checkbox checked>
<input name=name id=id type=checkbox checked="">
<input name=name id=id type=checkbox checked="yes">
<input name=name id=id type=checkbox checked="blue">
<input name=name id=id type=checkbox checked="false">

And only the following will be unchecked:

<input name=name id=id type=checkbox>

i'll leave this here since i will need to use it later. It's a source for a small binary compatible tool that will work equally well in assembly, C and C++.

I am using JsonProperty attributes when serializing but ignoring them when deserializing using this ContractResolver:

public class IgnoreJsonPropertyContractResolver: DefaultContractResolver
    {
        protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
        {
            var properties = base.CreateProperties(type, memberSerialization);
            foreach (var p in properties) { p.PropertyName = p.UnderlyingName; }
            return properties;
        }
    }

The ContractResolver just sets every property back to the class property name (simplified from Shimmy's solution). Usage:

var airplane= JsonConvert.DeserializeObject<Airplane>(json, 
    new JsonSerializerSettings { ContractResolver = new IgnoreJsonPropertyContractResolver() });

If a credit card is already added to a PayPal account then it won't let you use that card to process directly with Payments Advanced. The system expects buyers to login to PayPal and just choose that credit card as their funding source if they want to pay with it.

As for testing on the sandbox, I've always used old, expired credit cards I have laying around and they seem to work fine for me.

You could always try the ones starting on page 87 of the PayFlow documentation, too. They should work.

If you are using Ubuntu 18.04 along with Python 3.6, then pip or pip3 won't help. You need to install tkinter using following command:

sudo apt-get install python3-tk

You can use mx.DateTime module

import mx.DateTime as mt

t1 = mt.now() 
t2 = mt.now()
print int((t2-t1).seconds)

As Victor pointed out, the problem is with the alias. This can be avoided though, by putting the expression directly into the WHERE x IN y clause:

SELECT `users`.`first_name`,`users`.`last_name`,`users`.`email`,SUBSTRING(`locations`.`raw`,-6,4) AS `guaranteed_postcode`
FROM `users` LEFT OUTER JOIN `locations`
ON `users`.`id` = `locations`.`user_id`
WHERE SUBSTRING(`locations`.`raw`,-6,4) NOT IN #this is where the fake col is being used
(
 SELECT `postcode` FROM `postcodes` WHERE `region` IN
 (
  'australia'
 )
)

However, I guess this is very inefficient, since the subquery has to be executed for every row of the outer query.

It is always C:\Windows\System32\WindowsPowershell\v1.0. It was left like that for backward compability is what I heard or read somewhere.

Taken from the "logging cookbook":

# create logger with 'spam_application'
logger = logging.getLogger('spam_application')
logger.setLevel(logging.DEBUG)
# create file handler which logs even debug messages
fh = logging.FileHandler('spam.log')
fh.setLevel(logging.DEBUG)
logger.addHandler(fh)

And you're good to go.

P.S. Make sure to read the logging HOWTO as well.

Maybe just unbind the beforeunload event handler within the form's submit event handler:

jQuery('form').submit(function() {
    jQuery(window).unbind("beforeunload");
    ...
});
