Sometimes this error occurs for old javascript sdk. If you save locally javascript file. Update it. I prefer to load it form the facebook server all the time.

Here's another, simpler solution (underline's width is not most accurate but it was good enough for me)

I have a UIView (_view_underline) that has White background, height of 1 pixel and I update its width everytime I update the text

// It's a shame you have to do custom stuff to underline text
- (void) underline  {
    float width = [[_txt_title text] length] * 10.0f;
    CGRect prev_frame = [_view_underline frame];
    prev_frame.size.width = width;
    [_view_underline setFrame:prev_frame];
}

This is a my issues, my solution is as following: Use > for <, <for > , & for & ,"'" for ' , &quot for \"\"

I was looking to do this also. I have a large tile (literally an image of a tile) image which I'd like to rotate by just roughly 15 degrees and have repeated. You can imagine the size of an image which would repeat seamlessly, rendering the 'image editing program' answer useless.

My solution was give the un-rotated (just one copy :) tile image to psuedo :before element - oversize it - repeat it - set the container overflow to hidden - and rotate the generated :before element using css3 transforms. Bosh!

It is possible without any Javascript :)

The HTML:

<div class='box'>
    <div class='content'>Aspect ratio of 1:1</div>
</div> 

The CSS:

.box {
    position: relative;
    width:    50%; /* desired width */
}

.box:before {
    content:     "";
    display:     block;
    padding-top: 100%; /* initial ratio of 1:1*/
}

.content {
    position: absolute;
    top:      0;
    left:     0;
    bottom:   0;
    right:    0;
}

/* Other ratios - just apply the desired class to the "box" element */
.ratio2_1:before{
    padding-top: 50%;
}
.ratio1_2:before{
    padding-top: 200%;
}
.ratio4_3:before{
    padding-top: 75%;
}
.ratio16_9:before{
    padding-top: 56.25%;
}

I changed a few things to work with Option Explicit, and the code ran fine against a cell containing "abc.123", which returned "abc.12,". There were no compile errors.

Option Explicit ' This is new

Public Function ProcessString(input_string As String) As String
    ' The temp string used throughout the function
    Dim temp_string As String
    Dim i As Integer ' This is new
    Dim return_string As String ' This is new
    For i = 1 To Len(input_string)
        temp_string = Mid(input_string, i, 1)
        If temp_string Like "[A-Z, a-z, 0-9, :, -]" Then
            return_string = return_string & temp_string
        End If
    Next i
    return_string = Mid(return_string, 1, (Len(return_string) - 1))
    ProcessString = return_string & ", "
End Function

I'll suggest you post more of your relevant code (that calls this function). You've stated that last_name is a String, but it appears that may not be the case. Step through your code line by line and ensure that this is actually the case.

I just came across overloading.py (function overloading for Python 3) for anybody who may be interested.

From the linked repository's README file:

overloading is a module that provides function dispatching based on the types and number of runtime arguments.

When an overloaded function is invoked, the dispatcher compares the supplied arguments to available function signatures and calls the implementation that provides the most accurate match.

Features

Function validation upon registration and detailed resolution rules guarantee a unique, well-defined outcome at runtime. Implements function resolution caching for great performance. Supports optional parameters (default values) in function signatures. Evaluates both positional and keyword arguments when resolving the best match. Supports fallback functions and execution of shared code. Supports argument polymorphism. Supports classes and inheritance, including classmethods and staticmethods.

( If your url is correct and still get that error messege ) Do following steps to setup the Classpath in netbeans,

1. Create a new folder in your project workspace and add the downloaded .jar file(eg:- mysql-connector-java-5.1.35-bin.jar )
2. Right click your project > properties > Libraries > ADD jar/Folder Select the jar file in that folder you just make. And click OK.

Now you will see that .jar file will be included under the libraries. Now you will not need to use the line, Class.forName("com.mysql.jdbc.Driver"); also.

If above method did not work, check the mysql-connector version (eg:- 5.1.35) and try a newer or a suitable version for you.

I like Microsoft's XML Notepad 2007, but I don't know how it handles very large files, sorry.

From here (Google is your friend):

In a DTD, PCDATA and CDATA are used to assert something about the allowable content of elements and attributes, respectively. In an element's content model, #PCDATA says that the element contains (may contain) "any old text." (With exceptions as noted below.) In an attribute's declaration, CDATA is one sort of constraint you can put on the attribute's allowable values (other sorts, all mutually exclusive, include ID, IDREF, and NMTOKEN). An attribute whose allowable values are CDATA can (like PCDATA in an element) contain "any old text."

A potentially really confusing issue is that there's another "CDATA," also referred to as marked sections. A marked section is a portion of element (#PCDATA) content delimited with special strings: to close it. If you remember that PCDATA is "parsed character data," a CDATA section is literally the same thing, without the "parsed." Parsers transmit the content of a marked section to downstream applications without hiccupping every time they encounter special characters like < and &. This is useful when you're coding a document that contains lots of those special characters (like scripts and code fragments); it's easier on data entry, and easier on reading, than the corresponding entity reference.

So you can infer that the exception to the "any old text" rule is that PCDATA cannot include any of these unescaped special characters, UNLESS they fall within the scope of a CDATA marked section.

Now I need to connect that application from my local computer, but I don't know the JMX port number of the remote computer. Where can I find it? Or, must I restart that application with some VM parameters to specify the port number?

By default JMX does not publish on a port unless you specify the arguments from this page: How to activate JMX...

-Dcom.sun.management.jmxremote # no longer required for JDK6
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false # careful with security implications
-Dcom.sun.management.jmxremote.authenticate=false # careful with security implications

If you are running you should be able to access any of those system properties to see if they have been set:

if (System.getProperty("com.sun.management.jmxremote") == null) {
    System.out.println("JMX remote is disabled");
} else [
    String portString = System.getProperty("com.sun.management.jmxremote.port");
    if (portString != null) {
        System.out.println("JMX running on port "
            + Integer.parseInt(portString));
    }
}

Depending on how the server is connected, you might also have to specify the following parameter. As part of the initial JMX connection, jconsole connects up to the RMI port to determine which port the JMX server is running on. When you initially start up a JMX enabled application, it looks its own hostname to determine what address to return in that initial RMI transaction. If your hostname is not in /etc/hosts or if it is set to an incorrect interface address then you can override it with the following:

-Djava.rmi.server.hostname=<IP address>

As an aside, my SimpleJMX package allows you to define both the JMX server and the RMI port or set them both to the same port. The above port defined with com.sun.management.jmxremote.port is actually the RMI port. This tells the client what port the JMX server is running on.

To increase the font size of netbeans 7.3.1 and 7.3 , you go from menu Tools>>Options>>"Fonts & Colors" (is an inner menu in the dialog window of Options)

At the "Syntax" tab ,every entry in the "Category:" list-box ,you will notice that the font has the value "Inherited". If you find in the "Category" list-box the entry with the name "Default" and change the font value of that, you will affect the font size of your editor, because everything is inherited from "Default" entry .

Another method is to increase temporary the font of the editor by a combination of keys. To find what are the keys go to the "Options" dialog window by Tools>> Options and then choose the "Keymap" menu entry and then in the "Search" textbox type "zoom text" and it will show you what combinations of keys for zooming in /out.

for example mine is the combination of "alt" key + mouse wheel up/down

EXISTS (or NOT EXISTS) is specially designed for checking if something exists and therefore should be (and is) the best option. It will halt on the first row that matches so it does not require a TOP clause and it does not actually select any data so there is no overhead in size of columns. You can safely use SELECT * here - no different than SELECT 1, SELECT NULL or SELECT AnyColumn... (you can even use an invalid expression like SELECT 1/0 and it will not break).

IF EXISTS (SELECT * FROM Products WHERE id = ?)
BEGIN
--do what you need if exists
END
ELSE
BEGIN
--do what needs to be done if not
END

SELECT x.name, x.summary, (x.summary / COUNT(*)) as percents_of_total
FROM tbl t
INNER JOIN 
(SELECT name, SUM(value) as summary
FROM tbl
WHERE year BETWEEN 2000 AND 2001
GROUP BY name) x ON x.name = t.name
GROUP BY x.name, x.summary

If for whatever reason you wanted to do it manually (without using a module like csv,pandas,numpy etc.):

with open('myfile.csv','w') as f:
    for sublist in mylist:
        for item in sublist:
            f.write(item + ',')
        f.write('\n')

Of course, rolling your own version can be error-prone and inefficient ... that's usually why there's a module for that. But sometimes writing your own can help you understand how they work, and sometimes it's just easier.

I suggest you to use URL rewrite mod is enough for your problem,I have the same problem but using URL rewrite mod and getting good SEO response. I can give you a small example. Example is that you consider WordPress , here the data is stored in database but using URL rewrite mod many WordPress websites getting good responses from Google and got rank also.

Example: wordpress url with out url rewrite mod -- domain.com/?p=123 after url rewrite mode -- domain.com/{title of article} like domain.com/seo-url-rewrite-mod

i think you have understood what i want to say you

Galen Gidman has posted a really good solution to the problem of a responsive sticky footer that does not have a fixed height. You can find his full solution on his blog: http://galengidman.com/2014/03/25/responsive-flexible-height-sticky-footers-in-css/

HTML

<header class="page-row">
  <h1>Site Title</h1>
</header>

<main class="page-row page-row-expanded">
  <p>Page content goes here.</p>
</main>

<footer class="page-row">
  <p>Copyright, blah blah blah.</p>
</footer>

CSS

html,
body { height: 100%; }

body {
  display: table;
  width: 100%;
}

.page-row {
  display: table-row;
  height: 1px;
}

.page-row-expanded { height: 100%; }

If you need a function try this.
First we'll create a type:

CREATE OR REPLACE TYPE T_TABLE IS OBJECT
(
    Field1 int
    , Field2 VARCHAR(25)
);
CREATE TYPE T_TABLE_COLL IS TABLE OF T_TABLE;
/

Then we'll create the function:

CREATE OR REPLACE FUNCTION TEST_RETURN_TABLE
RETURN T_TABLE_COLL
    IS
      l_res_coll T_TABLE_COLL;
      l_index number;
    BEGIN
      l_res_coll := T_TABLE_COLL();
      FOR i IN (
        WITH TAB AS
          (SELECT '1001' ID, 'A,B,C,D,E,F' STR FROM DUAL
          UNION
          SELECT '1002' ID, 'D,E,F' STR FROM DUAL
          UNION
          SELECT '1003' ID, 'C,E,G' STR FROM DUAL
          )
        SELECT id,
          SUBSTR(STR, instr(STR, ',', 1, lvl) + 1, instr(STR, ',', 1, lvl + 1) - instr(STR, ',', 1, lvl) - 1) name
        FROM
          ( SELECT ',' || STR || ',' AS STR, id FROM TAB
          ),
          ( SELECT level AS lvl FROM dual CONNECT BY level <= 100
          )
        WHERE lvl <= LENGTH(STR) - LENGTH(REPLACE(STR, ',')) - 1
        ORDER BY ID, NAME)
      LOOP
        IF i.ID = 1001 THEN
          l_res_coll.extend;
          l_index := l_res_coll.count;
          l_res_coll(l_index):= T_TABLE(i.ID, i.name);
        END IF;
      END LOOP;
      RETURN l_res_coll;
    END;
    /

Now we can select from it:

select * from table(TEST_RETURN_TABLE()); 

Output:

SQL> select * from table(TEST_RETURN_TABLE());

    FIELD1 FIELD2
---------- -------------------------
      1001 A
      1001 B
      1001 C
      1001 D
      1001 E
      1001 F

6 rows selected.

Obviously you'd need to replace the WITH TAB AS... bit with where you would be getting your actual data from. Credit Credit

This issue started occurring for me all of a sudden, so I was sure, there could be some other reason. On digging deep, it was a simple issue where I used http in the BaseUrl of Retrofit instead of https. So changing it to https solved the issue for me.

Simply use:

public static int[] intArrayToIntegerArray(int[] a) {
    Integer[] b = new Integer[a.length];
    for(int i = 0; i < array.length; i++){
        b[i] = a[i];
    }
    return g;
}

dir /s /b /a:d>output.txt will port it to a text file

This post already has a checked answer, but the answer doesn't filter for null values. The correct answer should prevent null values by using the Object::nonNull function as a predicate.

BigDecimal result = invoiceList.stream()
    .map(Invoice::total)
    .filter(Objects::nonNull)
    .filter(i -> (i.getUnit_price() != null) && (i.getQuantity != null))
    .reduce(BigDecimal.ZERO, BigDecimal::add);

This prevents null values from attempting to be summed as we reduce.

In this world of flashy new native functions, we sometimes forget the basics.

for (let i = 0; i < arr.length; i++) {
    console.log('index:', i, 'element:', arr[i]);
}

Clean, efficient, and you can still break the loop. Bonus! You can also start from the end and go backwards with i--!

Additional note: If you're using the value a lot within the loop, you may wish to do const value = arr[i]; at the top of the loop for an easy, readable reference.

Within Crystal, you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

If NumericText ({field}) then ToNumber ({field}) else 0

Alternatively, you might find it easier to convert the field's datatype within the query used in the report.

Since the accepted answer from "nsdel" is only avilable with one stylesheet in a document this is the adapted full working solution:

    /**
     * Gets styles by a classname
     * 
     * @notice The className must be 1:1 the same as in the CSS
     * @param string className_
     */
    function getStyle(className_) {

        var styleSheets = window.document.styleSheets;
        var styleSheetsLength = styleSheets.length;
        for(var i = 0; i < styleSheetsLength; i++){
            var classes = styleSheets[i].rules || styleSheets[i].cssRules;
            if (!classes)
                continue;
            var classesLength = classes.length;
            for (var x = 0; x < classesLength; x++) {
                if (classes[x].selectorText == className_) {
                    var ret;
                    if(classes[x].cssText){
                        ret = classes[x].cssText;
                    } else {
                        ret = classes[x].style.cssText;
                    }
                    if(ret.indexOf(classes[x].selectorText) == -1){
                        ret = classes[x].selectorText + "{" + ret + "}";
                    }
                    return ret;
                }
            }
        }

    }

Notice: The selector must be the same as in the CSS.

I was able to delete 19 million rows from my table of 21 million rows in matter of minutes. Here is my approach.

If you have a auto-incrementing primary key on this table, then you can make use of this primary key.

1. Get minimum value of primary key of the large table where readTime < dateadd(MONTH,-7,GETDATE()). (Add index on readTime, if not already present, this index will anyway be deleted along with the table in step 3.). Lets store it in a variable 'min_primary'

2. Insert all the rows having primary key > min_primary into a staging table (memory table if no. of rows is not large).

3. Drop the large table.

4. Recreate the table. Copy all the rows from staging table to main table.

5. Drop the staging table.

I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

I've found only this actually works.

There are two ways to write case statements, you seem to be using a combination of the two

case a.updatedDate
    when 1760 then 'Entered on' + a.updatedDate
    when 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

or

case 
    when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
    when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.

Scenario: Your domain: mydomain.com Domain you wish to send to: theirdomain.com

1. Determine the mail server you're sending to. Open a CMD prompt Type

NSLOOKUP 
 set q=mx 
 theirdomain.com

Response:

Non-authoritative answer: 
theirdomain.com MX preference = 50, mail exchanger = mail.theirdomain.com 
Nslookup_big

EDIT Be sure to type exit to terminate NSLOOKUP.

2. Connect to their mail server

SMTP communicates over port 25. We will now try to use TELNET to connect to their mail server "mail.theirdomain.com"

Open a CMD prompt

TELNET MAIL.THEIRDOMAIN.COM 25

You should see something like this as a response:

220 mx.google.com ESMTP 6si6253627yxg.6

Be aware that different servers will come up with different greetings but you should get SOMETHING. If nothing comes up at this point there are 2 possible problems. Port 25 is being blocked at your firewall, or their server is not responding. Try a different domain, if that works then it's not you.

3. Send an Email

Now, use simple SMTP commands to send a test email. This is very important, you CANNOT use the backspace key, it will work onscreen but not be interpreted correctly. You have to type these commands perfectly.

ehlo mydomain.com 
mail from:<[email protected]> 
rcpt to:<[email protected]> 
data 
This is a test, please do not respond
. 
quit

So, what does that all mean? EHLO - introduce yourself to the mail server HELO can also be used but EHLO tells the server to use the extended command set (not that we're using that).

MAIL FROM - who's sending the email. Make sure to place this is the greater than/less than brackets as many email servers will require this (Postini).

RCPT TO - who you're sending it to. Again you need to use the brackets. See Step #4 on how to test relaying mail!

DATA - tells the SMTP server that what follows is the body of your email. Make sure to hit "Enter" at the end.

. - the period alone on the line tells the SMTP server you're all done with the data portion and it's clear to send the email.

quit - exits the TELNET session.

4. Test SMTP relay Testing SMTP relay is very easy, and simply requires a small change to the above commands. See below:

ehlo mydomain.com 
mail from:<[email protected]> 
rcpt to:<[email protected]> 
data 
This is a test, please do not respond 
. 
quit

See the difference? On the RCPT TO line, we're sending to a domain that is not controlled by the SMTP server we're sending to. You will get an immediate error is SMTP relay is turned off. If you're able to continue and send an email, then relay is allowed by that server.

I recently bought a new SSD and went from Windows to Linux.My build times are now an order of magnitude faster, and no longer annoying.

Though it does not directly answer your question as to why it's slower than eclipse, it shows that the process is disk-bounded and an upgrade to an SSD might be a (somewhat expensive) solution. I'm guessing there will be people googling the issue and ending up here, who might appreciate my experience.

SQLAlchemy users can simply specify their field as convert_unicode=True.

Example: sqlalchemy.String(1000, convert_unicode=True)

SQLAlchemy will simply accept unicode objects and return them back, handling the encoding itself.

Since jsperf is still down at the moment, here is a jsfiddle that compares the performance of different methods. https://jsfiddle.net/qw9qf48j/

Try running the following program. You just have to be sure your window has the focus when you hit Return--to ensure that it does, first click the button a couple of times until you see some output, then without clicking anywhere else hit Return.

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")
root.bind('<Return>', func)

def onclick():
    print("You clicked the button")

button = tk.Button(root, text="click me", command=onclick)
button.pack()

root.mainloop()

Then you just have tweak things a little when making both the button click and hitting Return call the same function--because the command function needs to be a function that takes no arguments, whereas the bind function needs to be a function that takes one argument(the event object):

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")

def onclick(event=None):
    print("You clicked the button")

root.bind('<Return>', onclick)

button = tk.Button(root, text="click me", command=onclick)
button.pack()

root.mainloop()

Or, you can just forgo using the button's command argument and instead use bind() to attach the onclick function to the button, which means the function needs to take one argument--just like with Return:

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")

def onclick(event):
    print("You clicked the button")

root.bind('<Return>', onclick)

button = tk.Button(root, text="click me")
button.bind('<Button-1>', onclick)
button.pack()

root.mainloop()

Here it is in a class setting:

import tkinter as tk

class Application(tk.Frame):
    def __init__(self):
        self.root = tk.Tk()
        self.root.geometry("300x200")

        tk.Frame.__init__(self, self.root)
        self.create_widgets()

    def create_widgets(self):
        self.root.bind('<Return>', self.parse)
        self.grid()

        self.submit = tk.Button(self, text="Submit")
        self.submit.bind('<Button-1>', self.parse)
        self.submit.grid()

    def parse(self, event):
        print("You clicked?")

    def start(self):
        self.root.mainloop()


Application().start()

You can use a lambda:

Collectors.toMap(p -> p.getLast(), Function.identity())

or, more concisely, you can use a method reference using :::

Collectors.toMap(Person::getLast, Function.identity())

and instead of Function.identity, you can simply use the equivalent lambda:

Collectors.toMap(Person::getLast, p -> p)

If you use Netbeans you should get hints whenever an anonymous class can be replaced by a lambda.

Just check for the null value and return false to it:

@{ bool nullableValue = ((Model.nullableValue == null) || (Model.nullableValue == false)) ? false : true; }
@Html.CheckBoxFor(model => nullableValue)

VanillaJS is a term for library/framework free javascript.

Its sometimes ironically referred to as a library, as a joke for people who could be seen as mindlessly using different frameworks, especially jQuery.

Some people have gone so far to release this library, usually with an empty or comment-only js file.

My tip for You is that if You declare something try to avoid string, so if You have class Field it is better to use class System.Type to store the field type than a string. And for the sake of best solutions instead of creation new classes try to use those that has been created FiledInfo instead of creation new.

Update 2016

As this answer receives some attention, I want to hint to a more recommended way on doing this using Virtual Hosts: Apache: Redirect SSL

<VirtualHost *:80>
   ServerName mysite.example.com
   Redirect permanent / https://mysite.example.com/
</VirtualHost>

<VirtualHost _default_:443>
   ServerName mysite.example.com
   DocumentRoot /usr/local/apache2/htdocs
   SSLEngine On
# etc...
</VirtualHost>

Old answer, hacky thing given that your ssl-port is not set to 80, this will work:

RewriteEngine on

# force ssl
RewriteCond     %{SERVER_PORT} ^80$
RewriteRule     ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]

Note that this should be your first rewrite rule.

Edit: This code does the following. The RewriteCond(ition) checks wether the ServerPort of the request is 80 (which is the default http-port, if you specified another port, you would have to adjust the condition to it). If so, we match the whole url (.*) and redirect it to a https-url. %{SERVER_NAME} may be replaced with a specific url, but this way you don't have to alter the code for other projects. %{REQUEST_URI} is the portion of the url after the TLD (top-level-domain), so you will be redirected to where you came from, but as https.

The code

Private Sub Worksheet_Activate()
    Dim PvtTbl As PivotTable
        Cells.EntireColumn.AutoFit
        For Each PvtTbl In Worksheets("Sales Details").PivotTables
        PvtTbl.RefreshTable
        Next
End Sub 

works fine.

The code is used in the activate sheet module, thus it displays a flicker/glitch when the sheet is activated.

You can use the directive v-html to show it. like this:

<td v-html="desc"></td>

Take a look at the LobBasicSample for an example to use CLOB, BLOB, NLOB datatypes.

Just as @James says, it will order all records, then get the first 20 rows.

As it is so, you are guaranteed to get the 20 first published articles, the newer ones will not be shown.

In your situation, I recommend that you add desc to order by publish_date, if you want the newest articles, then the newest article will be first.

If you need to keep the result in ascending order, and still only want the 10 newest articles you can ask mysql to sort your result two times.

This query below will sort the result descending and limit the result to 10 (that is the query inside the parenthesis). It will still be sorted in descending order, and we are not satisfied with that, so we ask mysql to sort it one more time. Now we have the newest result on the last row.

select t.article 
from 
    (select article, publish_date 
     from table1
     order by publish_date desc limit 10) t 

order by t.publish_date asc;

If you need all columns, it is done this way:

select t.* 
from 
    (select * 
     from table1  
     order by publish_date desc limit 10) t 

order by t.publish_date asc;

I use this technique when I manually write queries to examine the database for various things. I have not used it in a production environment, but now when I bench marked it, the extra sorting does not impact the performance.

The else is only connected to the last if. You want elif:

if 'bad' in line:
    pass
elif 'naughty' in line:
    pass
else:
    newopen.write(line)

Also note that I removed the line substitution, as you don't write those lines anyway.

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

You can use this code...

public class Main {

    public static void main(String args[]) {
        String[] names = {"First", "Second", "Third"};//You Can Add More Names
        double[] amount = {20.0, 30.0, 40.0};//You Can Add More Amount

        int i = 0;

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

I realize this isn't a part of the answer, but on that note, I also think the availability of stable plugins for platforms like NetBeans and Eclipse play a part in which tool is a better fit for the task, or rather, which tool is the best fit for "you". That is, unless you really want to do it the CLI-way.

Both Eclipse (and everything based on it) and NetBeans sometimes have issues with remote file systems (such as SSH) and external updates of files; which is yet another reason why you want whatever you choose to work "seamlessly".

I'm trying to answer this question for myself right now too .. and I've boiled down the candidates to Git or Mercurial .. thank you all for providing useful inputs on this topic without going religious.

I had faced the same issue because of some dll files were missing from References of VS13. I went to the location http://scn.sap.com/docs/DOC-7824 and installed the newest pack. It resolved the issue.

For anyone else looking for help on this matter, or experiencing a FileNotFoundException or a FirstChanceException, check out my answer here:

In general you must be absolutely certain that you are meeting all of the requirements for making the reference - I know it's the obvious answer, but you're probably overlooking a relatively simple requirement.

I just realized that it's not enough to put a comment on p4bl0's answer, though Tom's answer clearly solves the problem:

return filename.replace(/^.*?\.([a-zA-Z0-9]+)$/, "$1");

I'm not really sure if that was the situation with Roundcube version from May '12, but for current one the answer is that you can't delete roundcube_sessauth cookie from JavaScript, as it is marked as HttpOnly. And this means it's not accessible from JS client side code and can be removed only by server side script or by direct user action (via some browser mechanics like integrated debugger or some plugin).

From the fine manual.

You must own the table to use ALTER TABLE.

Or be a database superuser.

PostgreSQL error messages are usually spot on. This one is spot on.

Package Explorer / View Menu / Package Presentation... / Hierarchical

The "View Menu" can be opened with Ctrl + F10, or the small arrow-down icon in the top-right corner of the Package Explorer.

You can add elements to your environment by using

os.environ['LD_LIBRARY_PATH'] = 'my_path'

and run subprocesses in a shell (that uses your os.environ) by using

subprocess.call('sqsub -np ' + var1 + '/homedir/anotherdir/executable', shell=True)

I do this on the server-side. That is, the form always submits to the same target, but I've got a server-side script who is responsible for redirecting to the appropriate location depending on what button was pressed.

If you have multiple buttons, such as

<form action="mypage" method="get">

  <input type="submit" name="retry" value="Retry" />
  <input type="submit" name="abort" value="Abort" />

</form>

Note : I used GET, but it works for POST too

Then you can easily determine which button was pressed - if the variable retry exists and has a value then retry was pressed, and if the variable abort exists and has a value then abort was pressed. This knowledge can then be used to redirect to the appropriate place.

This method needs no Javascript.

Note : that some browsers are capable of submitting a form without pressing any buttons (by pressing enter). Non-standard as this is, you have to account for it, by having a clear default action and activating that whenever no buttons were pressed. In other words, make sure your form does something sensible (whether that's displaying a helpful error message or assuming a default) when someone hits enter in a different form element instead of clicking a submit button, rather than just breaking.

As @TomMcKenzie says in a comment to another answer, date -r 123456789 is arguably a more common (i.e. more widely implemented) simple solution for times given as seconds since the Unix Epoch, but unfortunately there's no universal guaranteed portable solution.

The -d option on many types of systems means something entirely different than GNU Date's --date extension. Sadly GNU Date doesn't interpret -r the same as these other implementations. So unfortunately you have to know which version of date you're using, and many older Unix date commands don't support either option.

Even worse, POSIX date recognizes neither -d nor -r and provides no standard way in any command at all (that I know of) to format a Unix time from the command line (since POSIX Awk also lacks strftime()). (You can't use touch -t and ls because the former does not accept a time given as seconds since the Unix Epoch.)

Note though The One True Awk available direct from Brian Kernighan does now have the strftime() function built-in as well as a systime() function to return the current time in seconds since the Unix Epoch), so perhaps the Awk solution is the most portable.

if you right click on any of the rows you can export the item or the entire data set as HAR which appears to be a JSON format.

It shouldn't be terribly difficult to script up something to transform that to a csv if you really need it in excel, but if you're already scripting you might as well just use the script to ask your questions of the data.

If anyone knows how to drive the "load page, export data" part of the process from the command line I'd be quite interested in hearing how

Maybe not very elegant, but it does the job:

exec(open("script.py").read())

The way you are using await/async is poor at best, and it makes it hard to follow. You are mixing await with Task'1.Result, which is just confusing. However, it looks like you are looking at a final task result, rather than the contents.

I've rewritten your function and function call, which should fix your issue:

async Task<string> GetResponseString(string text)
{
    var httpClient = new HttpClient();

    var parameters = new Dictionary<string, string>();
    parameters["text"] = text;

    var response = await httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters));
    var contents = await response.Content.ReadAsStringAsync();

    return contents;
}

And your final function call:

Task<string> result = GetResponseString(text);
var finalResult = result.Result;

Or even better:

var finalResult = await GetResponseString(text);

Generally, when you create an index on a table, database will automatically use that index while searching for data in that table. You don't need to do anything about that.

However, in MSSQL, you can specify an index hint which can specify that a particular index should be used to execute this query. More information about this can be found here.

Index hint is also seems to be available for MySQL. Thanks to Tudor Constantine.

Here's a solution that allows you to return the key as well and only does one loop. It sorts the Object's entries (by val) and then returns the first and last one.

Additionally, it returns the sorted Object which can replace the existing Object so that future sorts will be faster because it will already be semi-sorted = better than O(n). It's important to note that Objects retain their order in ES6.

const maxMinVal = (obj) => {_x000D_
  const sortedEntriesByVal = Object.entries(obj).sort(([, v1], [, v2]) => v1 - v2);_x000D_
_x000D_
  return {_x000D_
    min: sortedEntriesByVal[0],_x000D_
    max: sortedEntriesByVal[sortedEntriesByVal.length - 1],_x000D_
    sortedObjByVal: sortedEntriesByVal.reduce((r, [k, v]) => ({ ...r, [k]: v }), {}),_x000D_
  };_x000D_
};_x000D_
_x000D_
const obj = {_x000D_
  a: 4, b: 0.5, c: 0.35, d: 5_x000D_
};_x000D_
_x000D_
console.log(maxMinVal(obj));

Use HttpClient to grab the contents of the URL. And then use the library from json.org to parse the JSON. I've used these two libraries on many projects and they have been robust and simple to use.

Other than that you can try using a Facebook API java library. I don't have any experience in this area, but there is a question on stack overflow related to using a Facebook API in java. You may want to look at RestFB as a good choice for a library to use.

From iOS 6.0 and above, toggling torch flash on/off,

- (void) toggleFlash {
    AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
    if ([device hasTorch] && [device hasFlash]){
        [device lockForConfiguration:nil];
        [device setFlashMode:(device.flashActive) ? AVCaptureFlashModeOff : AVCaptureFlashModeOn];
        [device setTorchMode:(device.torchActive) ? AVCaptureTorchModeOff : AVCaptureTorchModeOn];
        [device unlockForConfiguration];
    }
}

P.S. This approach is only suggestible if you don't have on/off function. Remember there's one more option Auto. i.e. AVCaptureFlashModeAuto and AVCaptureTorchModeAuto. To support auto mode as well, you've keep track of current mode and based on that change mode of flash & torch.

I'd prefer to use the .Find method directly on a range object containing the range of cells to be searched. For original poster's code it might look like:

Set cell = ActiveSheet.Columns("B:B").Find( _
    What:=celda, _
    After:=ActiveCell _
    LookIn:=xlFormulas, _
    LookAt:=xlWhole, _
    SearchOrder:=xlByRows, _
    SearchDirection:=xlNext, _
    MatchCase:=False, _
    SearchFormat:=False _
)

If cell Is Nothing Then
    'do something
Else
    'do something else
End If

I'd prefer to use more variables (and be sure to declare them) and let a lot of optional arguments use their default values:

Dim rng as Range
Dim cell as Range
Dim search as String

Set rng = ActiveSheet.Columns("B:B")
search = "String to Find"
Set cell = rng.Find(What:=search, LookIn:=xlFormulas, LookAt:=xlWhole, MatchCase:=False)

If cell Is Nothing Then
    'do something
Else
    'do something else
End If

I kept LookIn:=, LookAt::=, and MatchCase:= to be explicit about what is being matched. The other optional parameters control the order matches are returned in - I'd only specify those if the order is important to my application.

These are all good answers. BUT if you're feeling lazy, and the file isn't that big, and security is not an issue (you know you don't have a tainted filename), then you can shell out:

$x=`cat /tmp/foo`;    # note backticks, qw"cat ..." also works

I needed a dropdown in a editable grid myself with preselected dropdown values. Afaik, the selectlist data is provided by the controller to the view, so it is created before the view consumes it. Once the view consumes the SelectList, I hand it over to a custom helper that uses the standard DropDownList helper. So, a fairly light solution imo. Guess it fits in the ASP.Net MVC spirit at the time of writing; when not happy roll your own...

public static string DropDownListEx(this HtmlHelper helper, string name, SelectList selectList, object selectedValue)
{
    return helper.DropDownList(name, new SelectList(selectList.Items, selectList.DataValueField, selectList.DataTextField, selectedValue));
}

1. Whenever slicing (a:n) can be used, it can be replaced by fancy indexing (e.g. [a,b,c,...,n]). Fancy indexing is nothing more than listing explicitly all the index values instead of specifying only the limits.

2. Whenever fancy indexing can be used, it can be replaced by a list of Boolean values (a mask) the same size than the index. The value will be True for index values that would have been included in the fancy index, and False for the values that would have been excluded. It's another way of listing some index values, but which can be easily automated in NumPy and Pandas, e.g by a logical comparison (like in your case).

The second replacement possibility is the one used in your example. In:

iris_data.loc[iris_data['class'] == 'versicolor', 'class'] = 'Iris-versicolor'

the mask

iris_data['class'] == 'versicolor'

is a replacement for a long and silly fancy index which would be list of row numbers where class column (a Series) has the value versicolor.

Whether a Boolean mask appears within a .iloc or .loc (e.g. df.loc[mask]) indexer or directly as the index (e.g. df[mask]) depends on wether a slice is allowed as a direct index. Such cases are shown in the following indexer cheat-sheet:

^{Pandas indexers loc and iloc cheat-sheet}

I needed to spin freeipa container to have a working kdc and had to give it a hostname otherwise it wouldn't run. What eventually did work for me is setting the HOSTNAME env variable in compose:

version: 2
services:
  freeipa:
    environment:
      - HOSTNAME=ipa.example.test

Now its working:

docker exec -it freeipa_freeipa_1 hostname
ipa.example.test

A similar option to what was posted above by janderson would be so simply use the .GetAttribute method in selenium 2. Using this, you can grab any item that has a specific value or label that you are looking for. This can be used to determine if an element has a label, style, value, etc. A common way to do this is to loop through the items in the drop down until you find the one that you want and select it. In C#

int items = driver.FindElement(By.XPath("//path_to_drop_Down")).Count(); 
for(int i = 1; i <= items; i++)
{
    string value = driver.FindElement(By.XPath("//path_to_drop_Down/option["+i+"]")).GetAttribute("Value1");
    if(value.Conatains("Label_I_am_Looking_for"))
    {
        driver.FindElement(By.XPath("//path_to_drop_Down/option["+i+"]")).Click(); 
        //Clicked on the index of the that has your label / value
    }
}

Unit testing is about the output you get from a function/method/application. It does not matter at all how the result is produced, it just matters that it is correct. Therefore, your approach of counting calls to inner methods and such is wrong. What I tend to do is sit down and write what a method should return given certain input values or a certain environment, then write a test which compares the actual value returned with what I came up with.

You need to make sure requestAnimFrame stops being called once game == 1. A break statement only exits a traditional loop (e.g. while()).

function loop() {
    if (isPlaying) {
        jet1.draw();
        drawAllEnemies();
        if (game != 1) {
            requestAnimFrame(loop);
        }
    }
}

Or alternatively you could simply skip the second if condition and change the first condition to if (isPlaying && game !== 1). You would have to make a variable called game and give it a value of 0. Add 1 to it every game.

It's padding. From http://en.wikipedia.org/wiki/Base64:

In theory, the padding character is not needed for decoding, since the number of missing bytes can be calculated from the number of Base64 digits. In some implementations, the padding character is mandatory, while for others it is not used. One case in which padding characters are required is concatenating multiple Base64 encoded files.

I had a similar problem, I wanted to use a different user name for a svn+ssh repository. In the end, I used svn relocate (as described in in this answer. In my case, I'm using svn 1.6.11 and did the following:

svn switch --relocate \
    svn+ssh://olduser@svnserver/path/to/repo \
    svn+ssh://newuser@svnserver/path/to/repo

where svn+ssh://olduser@svnserver/path/to/repo can be found in the URL: line output of svn info command. This command asked me for the password of newuser.

Note that this change is persistent, i.e. if you want only temporarily switch to the new username with this method, you'll have to issue a similar command again after svn update etc.

The same way you declare any other variable, just use the bit type:

DECLARE @MyVar bit
Set @MyVar = 1  /* True */
Set @MyVar = 0  /* False */

SELECT * FROM [MyTable] WHERE MyBitColumn = @MyVar

You need to check for DBNull, not null. Additionally, two of your three ReplaceNull methods don't make sense. double and DateTime are non-nullable, so checking them for null will always be false...

Here is a Python function that splits a Pandas dataframe into train, validation, and test dataframes with stratified sampling. It performs this split by calling scikit-learn's function train_test_split() twice.

Consider a dataset that has a label upon which you want to perform the stratification. This label has its own distribution in the original dataset, say 75% foo, 15% bar and 10% baz. Now let's split the dataset into train, validation, and test into subsets using a 60/20/20 ratio, where each split retains the same distribution of the labels. See the illustration below:

Here is the example dataset:

df = pd.DataFrame( { 'A': list(range(0, 100)),
                     'B': list(range(100, 0, -1)),
                     'label': ['foo'] * 75 + ['bar'] * 15 + ['baz'] * 10 } )

df.head()
#    A    B label
# 0  0  100   foo
# 1  1   99   foo
# 2  2   98   foo
# 3  3   97   foo
# 4  4   96   foo

df.shape
# (100, 3)

df.label.value_counts()
# foo    75
# bar    15
# baz    10
# Name: label, dtype: int64

Now, let's call the split_stratified_into_train_val_test() function from above to get train, validation, and test dataframes following a 60/20/20 ratio.

df_train, df_val, df_test = \
    split_stratified_into_train_val_test(df, stratify_colname='label', frac_train=0.60, frac_val=0.20, frac_test=0.20)

The three dataframes df_train, df_val, and df_test contain all the original rows but their sizes will follow the above ratio.

df_train.shape
#(60, 3)

df_val.shape
#(20, 3)

df_test.shape
#(20, 3)

Further, each of the three splits will have the same distribution of the label, namely 75% foo, 15% bar and 10% baz.

df_train.label.value_counts()
# foo    45
# bar     9
# baz     6
# Name: label, dtype: int64

df_val.label.value_counts()
# foo    15
# bar     3
# baz     2
# Name: label, dtype: int64

df_test.label.value_counts()
# foo    15
# bar     3
# baz     2
# Name: label, dtype: int64

The difference between text/xml and application/xml is the default character encoding if the charset parameter is omitted:

Text/xml and application/xml behave differently when the charset parameter is not explicitly specified. If the default charset (i.e., US-ASCII) for text/xml is inconvenient for some reason (e.g., bad web servers), application/xml provides an alternative (see "Optional parameters" of application/xml registration in Section 3.2).

For text/xml:

Conformant with [RFC2046], if a text/xml entity is received with the charset parameter omitted, MIME processors and XML processors MUST use the default charset value of "us-ascii"[ASCII]. In cases where the XML MIME entity is transmitted via HTTP, the default charset value is still "us-ascii".

For application/xml:

If an application/xml entity is received where the charset parameter is omitted, no information is being provided about the charset by the MIME Content-Type header. Conforming XML processors MUST follow the requirements in section 4.3.3 of [XML] that directly address this contingency. However, MIME processors that are not XML processors SHOULD NOT assume a default charset if the charset parameter is omitted from an application/xml entity.

So if the charset parameter is omitted, the character encoding of text/xml is US-ASCII while with application/xml the character encoding can be specified in the document itself.

Now a rule of thumb on the internet is: “Be strict with the output but be tolerant with the input.” That means make sure to meet the standards as much as possible when delivering data over the internet. But build in some mechanisms to overlook faults or to guess when receiving and interpreting data over the internet.

So in your case just pick one of the two types (I recommend application/xml) and make sure to specify the used character encoding properly (I recommend to use the respective default character encoding to play safe, so in case of application/xml use UTF-8 or UTF-16).

I know am late for the Party. I've fixed the problem by calling TabLayout#setupWithViewPager(myViewPager); just after FragmentPagerAdapter#notifyDataSetChanged();

Jenkins uses Cron Expressions.

You can simply schedule hourly builds by just typing@hourly.

Open a Terminal window and navigate to your project directory. Run these sets of commands, depending on which compiler you have installed:

To compile multiple C++ files using clang++:

$ clang++ *.cpp 
$ ./a.out 

To compile multiple C++ files using g++:

$ g++ -c *.cpp 
$ g++ -o temp.exe *.o
$ ./temp.exe

If you need to know the Commit history only, So don't use much Meshed up and bulky plugins,

I will recommend you a Basic simple plugin like "Git Commits"

I use it too :

Enjoy

My contribution: I got this error because I created a package named 3lp. However, according to java spec, you are not allowed to name your package starts with a number. I changed it to _3lp, now it works.

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

In Eclipse, Goto Window-> Show View -> Other -> Android-> Logcat.

Logcat is nothing but a console of your Emulator or Device.

System.out.println does not work in Android. So you have to handle every thing in Logcat. More Info Look out this Documentation.

Edit 1: System.out.println is working on Logcat. If you use that the Tag will be like System.out and Message will be your message.

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

You can learn some tutorials for JSP page direct access database (mysql) here

Notes:

• import sql tag library in jsp page

  <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>

• then set datasource on page

  <sql:setDataSource var="ds" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://<yourhost>/<yourdb>" user="<user>" password="<password>"/>
  

• Now query what you want on page

  <sql:query dataSource="${ds}" var="result"> //ref  defined 'ds'
      SELECT * from <your-table>;
  </sql:query>
  

• Finally you can populate dropdowns on page using c:forEach tag to iterate result rows in select element

  <c:forEach var="row" items="${result.rows}"> //ref set var 'result' <option value='<c:out value="${row.key}"/>'><c:out value="${row.value}"/</option> </c:forEach>

Use NSNumberFormatter with maximumFractionDigits as below:

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.maximumFractionDigits = 2;
NSLog(@"%@", [formatter stringFromNumber:[NSNumber numberWithFloat:12.345]]);

And you will get 12.35

A Stack allows you to stack elements on top of each other, with the last element in the array taking the highest priority. You can use Align, Positioned, or Container to position the children of a stack.

Align

Widgets are moved by setting the alignment with Alignment, which has static properties like topCenter, bottomRight, and so on. Or you can take full control and set Alignment(1.0, -1.0), which takes x,y values ranging from 1.0 to -1.0, with (0,0) being the center of the screen.

  Stack(
      children: [
        Align(
          alignment: Alignment.topCenter,
          child: Container(
              height: 80,
              width: 80, color: Colors.blueAccent
          ),
        ),
        Align(
          alignment: Alignment.center,
          child: Container(
              height: 80,
              width: 80, color: Colors.deepPurple
          ),
        ),
        Container(
          alignment: Alignment.bottomCenter,
          // alignment: Alignment(1.0, -1.0),
          child: Container(
              height: 80,
              width: 80, color: Colors.amber
          ),
        )
      ]
  )

You could also use stringstream.

If you have the authority to edit the pages to be opened, you can href to 'A' page and in the A page you can put link to B page in onpageload attribute of body tag.

I had this error as well and for me it was an OU with a forward slash in the name: "File/Folder Access Groups".

This forum thread pointed me in the right direction. In the end, calling .Replace("/","\\/") on each path value before use solved the problem for me.

I was facing the issue, i found that that older ecj library is present in Apache Tomcat directory 1)remove old jar from Apache Tomcat library 2)clean the project 3)build it. It started working as expected.

My case was to print horizontal (landscape) summary section - so:

}).then((canvas) => {
  const img = canvas.toDataURL('image/jpg');
  new jsPDF({
        orientation: 'l', // landscape
        unit: 'pt', // points, pixels won't work properly
        format: [canvas.width, canvas.height] // set needed dimensions for any element
  });
  pdf.addImage(img, 'JPEG', 0, 0, canvas.width, canvas.height);
  pdf.save('your-filename.pdf');
});

In Java side, the date is usually represented by the (poorly designed, but that aside) java.util.Date. It is basically backed by the Epoch time in flavor of a long, also known as a timestamp. It contains information about both the date and time parts. In Java, the precision is in milliseconds.

In SQL side, there are several standard date and time types, DATE, TIME and TIMESTAMP (at some DB's also called DATETIME), which are represented in JDBC as java.sql.Date, java.sql.Time and java.sql.Timestamp, all subclasses of java.util.Date. The precision is DB dependent, often in milliseconds like Java, but it can also be in seconds.

In contrary to java.util.Date, the java.sql.Date contains only information about the date part (year, month, day). The Time contains only information about the time part (hours, minutes, seconds) and the Timestamp contains information about the both parts, like as java.util.Date does.

The normal practice to store a timestamp in the DB (thus, java.util.Date in Java side and java.sql.Timestamp in JDBC side) is to use PreparedStatement#setTimestamp().

java.util.Date date = getItSomehow();
Timestamp timestamp = new Timestamp(date.getTime());
preparedStatement = connection.prepareStatement("SELECT * FROM tbl WHERE ts > ?");
preparedStatement.setTimestamp(1, timestamp);

The normal practice to obtain a timestamp from the DB is to use ResultSet#getTimestamp().

Timestamp timestamp = resultSet.getTimestamp("ts");
java.util.Date date = timestamp; // You can just upcast.

They are exactly the same. When you use it be consistent. Use one of them in your database

How about pass?

Some view have there own double tap recognizers built in (MKMapView being an example). To get around this you will need to implement UIGestureRecognizerDelegate method shouldRecognizeSimultaneouslyWithGestureRecognizer and return YES:

First implement your double and single recognizers:

// setup gesture recognizers
UITapGestureRecognizer* singleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                                action:@selector(mapViewTapped:)];
singleTapRecognizer.delegate = self;
singleTapRecognizer.numberOfTapsRequired = 1;


UITapGestureRecognizer* doubleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                                      action:@selector(mapViewDoubleTapped:)];
doubleTapRecognizer.delegate = self;    // this allows
doubleTapRecognizer.numberOfTapsRequired = 2;
[singleTapRecognizer requireGestureRecognizerToFail:doubleTapRecognizer];

And then implement:

#pragma mark UIGestureRecognizerDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer
*)otherGestureRecognizer {  return YES; }

I found the best way to troubleshoot this issue is to create a .proj msbuild file and add your unit test projects which you hare having an issue into this file and execute the tests using the command line version of mstest. I found a small configuration issue in my app.config which only appeared when running the tests from mstest - otherwise the test project built just fine. Also you will find any indirect reference issues with this method as well. Once you can run the Unit test from the command line using mstest you can then do a clean solution, rebuild solution and your test should be discovered properly.

You can use android:stopWithTask="false"in manifest as bellow, This means even if user kills app by removing it from tasklist, your service won't stop.

 <service android:name=".service.StickyService"
                  android:stopWithTask="false"/>

SELECT SQL_CALC_FOUND_ROWS *
FROM   table1
WHERE  ...;

SELECT FOUND_ROWS();

FOUND_ROWS() must be called immediately after the query.

Your module name must be camelCase eg. pdfLib. I had same issue because I my module name was 'PdfLib' and after renaming it to 'pdfLib'. It worked. The issue was not in my device but in jenkins server. So, check and see if you have such modulenames

Why didn't someone tell me I was being a total noob? All I had to do was copy the dateutil directory to someplace in my Python path, and it was good to go.

Since Oracle inserted some md5hash in their download links, one cannot automatically assemble a download link for command line.

So I tinkered some nasty bash command line to get the latest jdk download link, download it and directly install via rpm. For all who are interested:

wget -q http://www.oracle.com/technetwork/java/javase/downloads/index.html -O ./index.html && grep -Eoi ']+>' index.html | grep -Eoi '/technetwork/java/javase/downloads/jdk8-downloads-[0-9]+.html' | (head -n 1) | awk '{print "http://www.oracle.com"$1}' | xargs wget --no-cookies --header "Cookie: gpw_e24=xxx; oraclelicense=accept-securebackup-cookie;" -O index.html -q && grep -Eoi '"filepath":"[^"]+jdk-8u[0-9]+-linux-x64.rpm"' index.html | grep -Eoi 'http:[^"]+' | xargs wget --no-cookies --header "Cookie: gpw_e24=xxx; oraclelicense=accept-securebackup-cookie;" -q -O ./jdk8.rpm && sudo rpm -i ./jdk8.rpm

The bold part should be replaced by the package of your liking.

SHA doesn't require anything but an input to be applied, while AES requires at least 3 things - what you're encrypting/decrypting, an encryption key, and the initialization vector.

MySQL function example:

Open the mysql terminal:

el@apollo:~$ mysql -u root -pthepassword yourdb
mysql>

Drop the function if it already exists

mysql> drop function if exists myfunc;
Query OK, 0 rows affected, 1 warning (0.00 sec)

Create the function

mysql> create function hello(id INT)
    -> returns CHAR(50)
    -> return 'foobar';
Query OK, 0 rows affected (0.01 sec)

Create a simple table to test it out with

mysql> create table yar (id INT);
Query OK, 0 rows affected (0.07 sec)

Insert three values into the table yar

mysql> insert into yar values(5), (7), (9);
Query OK, 3 rows affected (0.04 sec)
Records: 3  Duplicates: 0  Warnings: 0

Select all the values from yar, run our function hello each time:

mysql> select id, hello(5) from yar;
+------+----------+
| id   | hello(5) |
+------+----------+
|    5 | foobar   |
|    7 | foobar   |
|    9 | foobar   |
+------+----------+
3 rows in set (0.01 sec)

Verbalize and internalize what just happened:

You created a function called hello which takes one parameter. The parameter is ignored and returns a CHAR(50) containing the value 'foobar'. You created a table called yar and added three rows to it. The select statement runs the function hello(5) for each row returned by yar.

Check if the indexes are in place first.

SELECT *
FROM INFORMATION_SCHEMA.STATISTICS
WHERE TABLE_SCHEMA = '<schema>'

Below are the differences between CrudRepository and JpaRepository as:

CrudRepository

1. CrudRepository is a base interface and extends the Repository interface.
2. CrudRepository mainly provides CRUD (Create, Read, Update, Delete) operations.
3. Return type of saveAll() method is Iterable.
4. Use Case - To perform CRUD operations, define repository extending CrudRepository.

JpaRepository

1. JpaRepository extends PagingAndSortingRepository that extends CrudRepository.
2. JpaRepository provides CRUD and pagination operations, along with additional methods like flush(), saveAndFlush(), and deleteInBatch(), etc.
3. Return type of saveAll() method is a List.
4. Use Case - To perform CRUD as well as batch operations, define repository extends JpaRepository.

I just benchmarked the top answer posted above in my own code (a recursive tree walk) and the simple concat operator is actually faster than the BufferString.

func (r *record) String() string {
    buffer := bytes.NewBufferString("");
    fmt.Fprint(buffer,"(",r.name,"[")
    for i := 0; i < len(r.subs); i++ {
        fmt.Fprint(buffer,"\t",r.subs[i])
    }
    fmt.Fprint(buffer,"]",r.size,")\n")
    return buffer.String()
}

This took 0.81 seconds, whereas the following code:

func (r *record) String() string {
    s := "(\"" + r.name + "\" ["
    for i := 0; i < len(r.subs); i++ {
        s += r.subs[i].String()
    }
    s += "] " + strconv.FormatInt(r.size,10) + ")\n"
    return s
} 

only took 0.61 seconds. This is probably due to the overhead of creating the new BufferString.

Update: I also benchmarked the join function and it ran in 0.54 seconds.

func (r *record) String() string {
    var parts []string
    parts = append(parts, "(\"", r.name, "\" [" )
    for i := 0; i < len(r.subs); i++ {
        parts = append(parts, r.subs[i].String())
    }
    parts = append(parts, strconv.FormatInt(r.size,10), ")\n")
    return strings.Join(parts,"")
}

The better and correct solution is to have a directive. The scope is the same, whether in the controller of the directive or the main controller. Use $element to do DOM operations. The method defined in the directive controller is accessible in the main controller.

Example, finding a child element:

var app = angular.module('myapp', []);
app.directive("testDir", function () {
    function link(scope, element) { 

    }
    return {
        restrict: "AE", 
        link: link, 
        controller:function($scope,$element){
            $scope.name2 = 'this is second name';
            var barGridSection = $element.find('#barGridSection'); //helps to find the child element.
    }
    };
})

app.controller('mainController', function ($scope) {
$scope.name='this is first name'
});

FWIW, I was getting this error when I was accidentally making a GET request to an endpoint that was expecting a POST request. Presumably that was just that particular servers way of handling the problem.

Worked perfectly for me.

Well there's a problem with the creation of the ContactServiceImpl bean. First, make sure that the class is actually instantiated by debugging the no-args constructor when the Spring context is initiated and when an instance of ContactController is created.

If the ContactServiceImpl is actually instantiated by the Spring context, but it's simply not matched against your @Autowire annotation, try being more explicit in your annotation injection. Here's a guy dealing with a similar problem as yours and giving some possible solutions:

http://blogs.sourceallies.com/2011/08/spring-injection-with-resource-and-autowired/

If you ask me, I think you'll be ok if you replace

@Autowired
private ContactService contactService;

with:

@Resource
@Qualifier("contactService")
private ContactService contactService;

If I were you, I would set the scale of the BigDecimal so that I dont end up on lengthy numbers. The integer 2 in the BigDecimal initialization below sets the scale.

Since you have lots of mismatch of data type, I have changed it accordingly to adjust.

class Payment   
{
      BigDecimal itemCost=new BigDecimal(BigInteger.ZERO,  2);
      BigDecimal totalCost=new BigDecimal(BigInteger.ZERO,  2);

     public BigDecimal calculateCost(int itemQuantity,BigDecimal itemPrice)
       { 
           BigDecimal   itemCost = itemPrice.multiply(new BigDecimal(itemQuantity)); 
             return totalCost.add(itemCost); 
       }
  }

BigDecimals are Object , not primitives, so make sure you initialize itemCost and totalCost , otherwise it can give you nullpointer while you try to add on totalCost or itemCost

There are two primary contenders for python apps on Android

Chaquopy

https://chaquo.com/chaquopy/

This integrates with the Android build system, it provides a Python API for all android features. To quote the site "The complete Android API and user interface toolkit are directly at your disposal."

Beeware (Toga widget toolkit)

https://pybee.org/

This provides a multi target transpiler, supports many targets such as Android and iOS. It uses a generic widget toolkit (toga) that maps to the host interface calls.

Which One?

Both are active projects and their github accounts shows a fair amount of recent activity.

Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms. If you have basic designs, and a desire to expand to other platforms this should work out well for you.

On the other hand, Chaquopy is a much more precise in its mapping of the python API to Android. It also allows you to mix in Java, useful if you want to use existing code from other resources. If you have strict design targets, and predominantly want to target Android this is a much better resource.

Try this code

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if(id == android.R.id.home){
        //You can get 
    }
    return super.onOptionsItemSelected(item);
}

Add below code to your onCreate() metod

ActionBar ab = getSupportActionBar();
    ab.setDisplayHomeAsUpEnabled(true);

Try this to detect the Enter key pressed.

$(document).on("keypress", function(e){
    if(e.which == 13){
        alert("You've pressed the enter key!");
    }
});

See demo @ detect enter key press on keyboard

As well as \singlespacing mentioned previously to reduce the height of the table, a useful way to reduce the width of the table is to add \tabcolsep=0.11cm before the \begin{tabular} command and take out all the vertical lines between columns. It's amazing how much space is used up between the columns of text. You could reduce the font size to something smaller than \small but I normally wouldn't use anything smaller than \footnotesize.

Here is a ZipFileIterator (like a java Iterator, but for zip files):

package ch.epfl.bbp.io;

import java.io.BufferedInputStream;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Iterator;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class ZipFileIterator implements Iterator<File> {

    private byte[] buffer = new byte[1024];

    private FileInputStream is;
    private ZipInputStream zis;
    private ZipEntry ze;

    public ZipFileIterator(File file) throws FileNotFoundException {
    is = new FileInputStream(file);
    zis = new ZipInputStream(new BufferedInputStream(is));
    }

    @Override
    public boolean hasNext() {
    try {
        return (ze = zis.getNextEntry()) != null;
    } catch (IOException e) {
        e.printStackTrace();
    }
    return false;
    }

    @Override
    public File next() {
    try {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int count;

        String filename = ze.getName();
        File tmpFile = File.createTempFile(filename, "tmp");
        tmpFile.deleteOnExit();// TODO make it configurable
        FileOutputStream fout = new FileOutputStream(tmpFile);

        while ((count = zis.read(buffer)) != -1) {
        baos.write(buffer, 0, count);
        byte[] bytes = baos.toByteArray();
        fout.write(bytes);
        baos.reset();
        }
        fout.close();
        zis.closeEntry();

        return tmpFile;

    } catch (Exception e) {
        throw new RuntimeException(e);
    }
    }

    @Override

    throw new RuntimeException("not implemented");
    }

    public void close() {
    try {
        zis.close();
        is.close();
    } catch (IOException e) {// nope
    }
    }
}

You can verify the response in 3 ways as per the Google reCAPTCHA documentation:

1. g-recaptcha-response: Once user checks the checkbox (I am not a robot), a field with id g-recaptcha-response gets populated in your HTML.
   You can now use the value of this field to know if the user is a bot or not, using the below mentioed lines:-

   var captchResponse = $('#g-recaptcha-response').val();
   if(captchResponse.length == 0 )
       //user has not yet checked the 'I am not a robot' checkbox
   else 
       //user is a verified human and you are good to submit your form now
   

2. Before you are about to submit your form, you can make a call as follows:-

   var isCaptchaValidated = false;
   var response = grecaptcha.getResponse();
   if(response.length == 0) {
       isCaptchaValidated = false;
       toast('Please verify that you are a Human.');
   } else {
       isCaptchaValidated = true;
   }
   
   
   if (isCaptchaValidated ) {
       //you can now submit your form
   }
   

3. You can display your reCAPTCHA as follows:-

   <div class="col s12 g-recaptcha" data-sitekey="YOUR_PRIVATE_KEY" data-callback='doSomething'></div>
   

   And then define the function in your JavaScript, which can also be used to submit your form.

   function doSomething() { alert(1); }
   

   Now, once the checkbox (I am not a robot) is checked, you will get a callback to the defined callback, which is doSomething in your case.

In my case i was using jQuery validation rules with

submitHandler function and submitting the data as new FormData(form);

Select Option

<select class="selectpicker" id="branch" name="branch" multiple="multiple" title="Of Branch" data-size="6" required>
  <option disabled>Multiple Branch Select</option>
  <option value="Computer">Computer</option>
  <option value="Civil">Civil</option>
  <option value="EXTC">EXTC</option>
  <option value="ETRX">ETRX</option>
  <option value="Mechinical">Mechinical</option>
</select>

<input type="hidden" name="new_branch" id="new_branch">

Get the multiple selected value and set to new_branch input value & while submitting the form get value from new_branch

Just replace hidden with text to view on the output

<input type="text" name="new_branch" id="new_branch">

Script (jQuery / Ajax)

<script>
    $(document).ready(function() {

      $('#branch').on('change', function(){
          var selected = $(this).find("option:selected"); //get current selected value
          var arrSelected = []; //Array to store your multiple value in stack
          selected.each(function(){
            arrSelected.push($(this).val()); //Stack the value
          });
          $('#new_branch').val(arrSelected); //It will set the multiple selected value to input new_branch
      });

    });
</script>

In addition to the other answers, on a recent C library (Posix 2008 compliant), you could use getline. See this answer (to a related question).

You can always try to kill the process in case you see this kind of issues. You can get the process ID either from PS or from pid file and kill the process.

You could use the Get method and check for null as the method will return null if the NameValueCollection does not contain the specified key.

See MSDN.

I wanted to update at the comment earlier made by DaShaun, but as it is my first time commenting, application didn't allow me.

Nonetheless, I am using eclipse and after I added the below mention code snippet to my pom.xml as suggested by Dashun and I ran the mvn clean package to generate the avro source files, but I was still getting compilation error in the workspace.

I right clicked on project_name -> maven -> update project and updated the project, which added the target/generated-sources as a source folder to my eclipse project.

There are three methods of passing an object to a function as a parameter:

1. Pass by reference
2. pass by value
3. adding constant in parameter

Go through the following example:

class Sample
{
public:
    int *ptr;
    int mVar;

    Sample(int i)
    {
        mVar = 4;
        ptr = new int(i);
    }

    ~Sample()
    {
        delete ptr;
    }

    void PrintVal()
    {
        cout << "The value of the pointer is " << *ptr << endl
             << "The value of the variable is " << mVar;
   }
};

void SomeFunc(Sample x)
{
cout << "Say i am in someFunc " << endl;
}


int main()
{

  Sample s1= 10;
  SomeFunc(s1);
  s1.PrintVal();
  char ch;
  cin >> ch;
}

Output:

Say i am in someFunc
The value of the pointer is -17891602
The value of the variable is 4

Unfortunately, all answers so far do not take into account that "a" must not be considered equal to "A" when it comes to sorting.

String[] array = {"b", "A", "C", "B", "a"};

// Approach 1
Arrays.sort(array);
// array is [A, B, C, a, b]

// Approach 2
Arrays.sort(array, String.CASE_INSENSITIVE_ORDER);
// array is [A, a, b, B, C]

// Approach 3
Arrays.sort(array, java.text.Collator.getInstance());
// array is [a, A, b, B, C]

In approach 1 any lower case letters are considered greater than any upper case letters.

Approach 2 makes it worse, since CASE_INSENSITIVE_ORDER considers "a" and "A" equal (comparation result is 0). This makes sorting non-deterministic.

Approach 3 (using a java.text.Collator) is IMHO the only way of doing it correctly, since it considers "a"and "A" not equal, but puts them in the correct order according to the current (or any other desired) Locale.

You have the pipe the other way around and you need to echo the query, like this:

myvariable=$(echo "SELECT A, B, C FROM table_a" | mysql db -u $user -p $password)

Another alternative is to use only the mysql client, like this

myvariable=$(mysql db -u $user -p $password -se "SELECT A, B, C FROM table_a")

(-s is required to avoid the ASCII-art)

Now, BASH isn't the most appropriate language to handle this type of scenarios, especially handling strings and splitting SQL results and the like. You have to work a lot to get things that would be very, very simple in Perl, Python or PHP.

For example, how will you get each of A, B and C on their own variable? It's certainly doable, but if you do not understand pipes and echo (very basic shell stuff), it will not be an easy task for you to do, so if at all possible I'd use a better suited language.

I believe fcntl() is a POSIX function. Where as ioctl() is a standard UNIX thing. Here is a list of POSIX io. ioctl() is a very kernel/driver/OS specific thing, but i am sure what you use works on most flavors of Unix. some other ioctl() stuff might only work on certain OS or even certain revs of it's kernel.

If you provide 6 hex digits, that means RGB (2 hex digits for each value of red, green and blue).

If you provide 8 hex digits, it's an ARGB (2 hex digits for each value of alpha, red, green and blue respectively).

So by removing the final 55 you're changing from A=B4, R=55, G=55, B=55 (a mostly transparent grey), to R=B4, G=55, B=55 (a fully-non-transparent dusky pinky).

See the "Color" documentation for the supported formats.

There is an important detail that has been omitted in the answer above.

MySQL imposes a limit of 65,535 bytes for the max size of each row. The size of a VARCHAR column is counted towards the maximum row size, while TEXT columns are assumed to be storing their data by reference so they only need 9-12 bytes. That means even if the "theoretical" max size of your VARCHAR field is 65,535 characters you won't be able to achieve that if you have more than one column in your table.

Also note that the actual number of bytes required by a VARCHAR field is dependent on the encoding of the column (and the content). MySQL counts the maximum possible bytes used toward the max row size, so if you use a multibyte encoding like utf8mb4 (which you almost certainly should) it will use up even more of your maximum row size.

Correction: Regardless of how MySQL computes the max row size, whether or not the VARCHAR/TEXT field data is ACTUALLY stored in the row or stored by reference depends on your underlying storage engine. For InnoDB the row format affects this behavior. (Thanks Bill-Karwin)

Reasons to use TEXT:

• If you want to store a paragraph or more of text
• If you don't need to index the column
• If you have reached the row size limit for your table

Reasons to use VARCHAR:

• If you want to store a few words or a sentence
• If you want to index the (entire) column
• If you want to use the column with foreign-key constraints

A typical situation with multiple cascasing paths will be this: A master table with two details, let's say "Master" and "Detail1" and "Detail2". Both details are cascade delete. So far no problems. But what if both details have a one-to-many-relation with some other table (say "SomeOtherTable"). SomeOtherTable has a Detail1ID-column AND a Detail2ID-column.

Master { ID, masterfields }

Detail1 { ID, MasterID, detail1fields }

Detail2 { ID, MasterID, detail2fields }

SomeOtherTable {ID, Detail1ID, Detail2ID, someothertablefields }

In other words: some of the records in SomeOtherTable are linked with Detail1-records and some of the records in SomeOtherTable are linked with Detail2 records. Even if it is guaranteed that SomeOtherTable-records never belong to both Details, it is now impossible to make SomeOhterTable's records cascade delete for both details, because there are multiple cascading paths from Master to SomeOtherTable (one via Detail1 and one via Detail2). Now you may already have understood this. Here is a possible solution:

Master { ID, masterfields }

DetailMain { ID, MasterID }

Detail1 { DetailMainID, detail1fields }

Detail2 { DetailMainID, detail2fields }

SomeOtherTable {ID, DetailMainID, someothertablefields }

All ID fields are key-fields and auto-increment. The crux lies in the DetailMainId fields of the Detail tables. These fields are both key and referential contraint. It is now possible to cascade delete everything by only deleting master-records. The downside is that for each detail1-record AND for each detail2 record, there must also be a DetailMain-record (which is actually created first to get the correct and unique id).

Thanks Aakash for recommending JIDE MultilineLabel. JIDE's StyledLabel is also enhanced recently to support multiple line. I would recommend it over the MultilineLabel as it has many other great features. You can check out an article on StyledLabel below. It is still free and open source.

http://www.jidesoft.com/articles/StyledLabel.pdf

Use command substitution instead of quotes to execute find instead of passing the command as a string:

for line in $(find . -iname '*.txt'); do 
     echo $line
     ls -l $line; 
done

This worked for me Android Studio 4.0.1:

1. Close Android Studio.

2. Navigate to C:\Users[Username].AndroidStudio4.0\config\options

3. Locate recentProjects.xml and open it.

4. Scroll down the page you will notice: <option name="lastProjectLocation" value="$USER_HOME$/AndroidStudioProjects" />

5. Change $USER_HOME$/AndroidStudioProjects to your desired location: /home/USER/AndroidStudioProjects/

6. Reopen Android studio.

before for loop :

$data = array();

then in your loop:

$data[] = array($catagory => $question);

You could us the 'net use' command:

var p = System.Diagnostics.Process.Start("net.exe", "use K: \\\\Server\\path");
var isCompleted = p.WaitForExit(5000);

If that does not work in a service, try the Winapi and PInvoke WNetAddConnection2

Edit: Obviously I misunderstood you - you can not change the sourcecode of the service, right? In that case I would follow the suggestion by mdb, but with a little twist: Create your own service (lets call it mapping service) that maps the drive and add this mapping service to the dependencies for the first (the actual working) service. That way the working service will not start before the mapping service has started (and mapped the drive).

I also suggest using contourf(Z). For my problem, I wanted to visualize a 3D histogram in 2D, but the contours were too smooth to represent a top view of histogram bars.

So in my case, I prefer to use jucestain's answer. The default shading faceted of pcolor() is more suitable. However, pcolor() does not use the last row and column of the plotted matrix. For this, I used the padarray() function:

pcolor(padarray(Z,[1 1],0,'post'))

Sorry if that is not really related to the original post

When I click 'save' button, it has this error. Based on the answers in this post and other websites, I just found the solution. My jupyter notebook is installed from pip. So I access it by typing 'jupyter notebook' in the windows command line.

(1) open a new command window, then open a new jupyter notebook. try to save again in the old notebook, this time ,the error is 'fail: forbidden'

(2) Then in the old notebook, click 'download as', it will pop out a new windows ask you the token.

(3) open another command window, then open another jupyter notebook, type 'jupyter notebook list' copy the code after 'token=' and before :: to the box you just saw. You can save this time. If it fails, you can try another token in the list

Easiest option:

<script type="text/javascript">
  function frameload(){
   alert("iframe loaded")
  }
</script>

<iframe onload="frameload()" src=...>

For dropping all documents in a collection:

myMongooseModel.collection.drop();

as seen in the tests

In addition to using jQuery methods, you can use the native cells collection that the <tr> gives you.

$(t)[0].cells[1].innerHTML

Assuming t is a DOM element, you could bypass the jQuery object creation.

t.cells[1].innerHTML

You cannot do this:

vector<string> name(5); //error in these 2 lines
vector<int> val(5,0);

in a class outside of a method.

You can initialize the data members at the point of declaration, but not with () brackets:

class Foo {
    vector<string> name = vector<string>(5);
    vector<int> val{vector<int>(5,0)};
};

Before C++11, you need to declare them first, then initialize them e.g in a contructor

class Foo {
    vector<string> name;
    vector<int> val;
 public:
  Foo() : name(5), val(5,0) {}
};

If you are given this format it takes like a link to another page or another link.partial view majorly used for renduring the html files from one place to another.

How about:

    For Each oSheet In ActiveWorkbook.Sheets
        If oSheet.ListObjects.Count > 0 Then
          oCmbBox.AddItem oSheet.Name
        End If
    Next oSheet

I don't like this code:

foreach(var user in db.Users)

As an alternative, one might do something like this, which worked for me:

var listOfUsers = db.Users.Select(r => new UserModel
                         {
                             userModel.FirstName = r.FirstName;
                             userModel.LastName = r.LastName;

                         });

return listOfUsers.ToList();

However, I ended up using Lucas Roselli's solution.

Update: Simplified by returning an anonymous object:

var listOfUsers = db.Users.Select(r => new 
                         {
                             FirstName = r.FirstName;
                             LastName = r.LastName;
                         });

return listOfUsers.ToList();

If you want to use the JavaScript download functionality then you can also do

 <a onclick=“window.open(‘info.pdf) class="btn btn-large pull-right"><i class="icon-download-alt"> </i> Download Brochure </a>

Also remember to paste the info.pdf file in your public directory of your project

1. Right click on folder.

2. Click Properties

3. Click Security Tab. You will see something like this:

4. Click "Edit..." button in above screen. You will see something like this:

5. Click "Add..." button in above screen. You will see something like this:

6. Click "Locations..." button in above screen. You will see something like this. Now, go to the very of top of this tree structure and select your computer name, then click OK.

7. Now type "iis apppool\your_apppool_name" and click "Check Names" button. If the apppool exists, you will see your apppool name in the textbox with underline in it. Click OK button.

8. Check/uncheck whatever access you need to grant to the account

9. Click Apply button and then OK.

A different approach, just for kicks:

Console.WriteLine(string.Join("\t", list));

This might hopefully help someone else, as I ended up spending hours trying to chase this down.

If you have a function within your model by the same name, this will remove the value. Pretty obvious in hindsight, but nonetheless.

So, if you have something like this:

class Foobar(models.Model):
    [...]
    something = models.BooleanField(default=False)

    [...]
    def something(self):
        return [some logic]

In that case, the function will override the setting above, making it "invisible" to makemigrations.

This is an old topic, but I will add my experience, maybe someone finds this helpful

solution1:

              Uri uriDelete=Uri.parse (adapter.getNoteAt (viewHolder.getAdapterPosition ()).getImageuri ());//getter getImageuri on my object from adapter that returns String with content uri

here I initialize Content resolver and delete it with a passed parameter of that URI

            ContentResolver contentResolver = getContentResolver ();
            contentResolver.delete (uriDelete,null ,null );

solution2(my first solution-from head in this time I do know that ): content resolver exists...

I recently had a similar problem and ended up fixing it using a mixture of different solutions.

The first and most simple one was to use two tables, one for the headers and one for the body. This works but the headers and the body columns are not aligned. And, since I wanted to use the auto-size that comes with twitter bootstrap tables I ended up creating a Javascript function that changes the headers when: the body is rendered; the windows is resized; the data in the column changes, etc.

Here is some of the code I used:

        <table class="table table-striped table-hover" style="margin-bottom: 0px;">
        <thead>
            <tr>
                <th data-sort="id">Header 1</i></th>
                <th data-sort="guide">Header 2</th>
                <th data-sort="origin">Header 3</th>
                <th data-sort="supplier">Header 4</th>
            </tr>
        </thead>
    </table>
    <div class="bodycontainer scrollable">
        <table class="table table-hover table-striped table-scrollable">
            <tbody id="rows"></tbody>
        </table>
    </div>

The headers and the body are divided in two separate tables. One of them is inside a DIV with the necessary style to generate the vertical scrollbars. Here is the CSS I used:

.bodycontainer {
  //height: 200px
  width: 100%;
  margin: 0;
}

.table-scrollable {
  margin: 0px;
  padding: 0px;
}

I commented the height here because I a wanted the table to reach the bottom of the page, whatever the page height might be.

The data-sort attributes I used in the headers are also used in every td. This way I could get the width and the padding of every td and the width of the row. Using the data-sort attributes I set using CSS the padding and width of each header accordingly and of the header row which is always bigger since it doesn´t have a scrollbar. Here is the function using coffeescript:

fixHeaders: =>
  for header, i in @headers
    tdpadding = parseInt(@$("td[data-sort=#{header}]").css('padding'))
    tdwidth = parseInt(@$("td[data-sort=#{header}]").css('width'))
    @$("th[data-sort=#{header}]").css('padding', tdpadding)
    @$("th[data-sort=#{header}]").css('width', tdwidth)
    if (i+1) == @headers.length
      trwidth = @$("td[data-sort=#{header}]").parent().css('width')
      @$("th[data-sort=#{header}]").parent().parent().parent().css('width', trwidth)
      @$('.bodycontainer').css('height', window.innerHeight - ($('html').outerHeight() -@$('.bodycontainer').outerHeight() ) ) unless @collection.length == 0

Here I assume that you have an array of the headers called @headers.

It is not pretty but it works. Hope it helps someone.

In the scenario you would NOT like to use the onChange handler on the input DOM, you can use the onClick property as an alternative. The defaultChecked, the condition may leave a fixed state for v16 IINM.

 class CrossOutCheckbox extends Component {
      constructor(init){
          super(init);
          this.handleChange = this.handleChange.bind(this);
      }
      handleChange({target}){
          if (target.checked){
             target.removeAttribute('checked');
             target.parentNode.style.textDecoration = "";
          } else {
             target.setAttribute('checked', true);
             target.parentNode.style.textDecoration = "line-through";
          }
      }
      render(){
         return (
            <span>
              <label style={{textDecoration: this.props.complete?"line-through":""}}>
                 <input type="checkbox"
                        onClick={this.handleChange}
                        defaultChecked={this.props.complete}
                  />
              </label>
                {this.props.text}
            </span>
        )
    }
 }

I hope this helps someone in the future.

I assume bash is running on a vt100-compatible terminal in which the user did not explicitly turn off the support for formatting.

First, turn on support for special characters in echo, using -e option. Later, use ansi escape sequence ESC[1m, like:

echo -e "\033[1mSome Text"

More on ansi escape sequences for example here: ascii-table.com/ansi-escape-sequences-vt-100.php

Try to use 3rd party tool, such as SQL Data Examiner which compares Oracle databases and shows you differences.

Just add a new datafile for the existing tablespace

ALTER TABLESPACE LEGAL_DATA ADD DATAFILE '/u01/oradata/userdata03.dbf' SIZE 200M;

To find out the location and size of your data files:

SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES WHERE TABLESPACE_NAME = 'LEGAL_DATA';

Use substitute instead.

labNames <- c('xLab','yLab')
plot(c(1:10),
     xlab=substitute(paste(nn, x^2), list(nn=labNames[1])),
     ylab=substitute(paste(nn, y^2), list(nn=labNames[2])))

Without seeing your full code, this is impossible to answer with any certainty. The error usually occurs when you are trying to unload a control rather than the form.

Make sure that you don't have the "me" in brackets.

Also if you can post the full code for the userform it would help massively.

Another and easy way using cat command

cat filename | awk '{print $2,$3,$4,$5,$6,$1}' > newfilename

See http://blog.headius.com/2009/01/my-favorite-hotspot-jvm-flags.html

-Xms and -Xmx set the minimum and maximum sizes for the heap. Touted as a feature, Hotspot puts a cap on heap size to prevent it from blowing out your system. So once you figure out the max memory your app needs, you cap it to keep rogue code from impacting other apps. Use these flags like -Xmx512M, where the M stands for MB. If you don't include it, you're specifying bytes. Several flags use this format. You can also get a minor startup perf boost by setting minimum higher, since it doesn't have to grow the heap right away.

-XX:MaxPermSize=###M sets the maximum "permanent generation" size. Hotspot is unusual in that several types of data get stored in the "permanent generation", a separate area of the heap that is only rarely (or never) garbage-collected. The list of perm-gen hosted data is a little fuzzy, but it generally contains things like class metadata, bytecode, interned strings, and so on (and this certainly varies across Hotspot versions). Because this generation is rarely or never collected, you may need to increase its size (or turn on perm-gen sweeping with a couple other flags). In JRuby especially we generate a lot of adapter bytecode, which usually demands more perm gen space.

EDIT: From ECMAScript 2018 onwards, lookbehind assertions (even unbounded) are supported natively.

In previous versions, you can do this:

^(?:(?!filename\.js$).)*\.js$

This does explicitly what the lookbehind expression is doing implicitly: check each character of the string if the lookbehind expression plus the regex after it will not match, and only then allow that character to match.

^                 # Start of string
(?:               # Try to match the following:
 (?!              # First assert that we can't match the following:
  filename\.js    # filename.js 
  $               # and end-of-string
 )                # End of negative lookahead
 .                # Match any character
)*                # Repeat as needed
\.js              # Match .js
$                 # End of string

Another edit:

It pains me to say (especially since this answer has been upvoted so much) that there is a far easier way to accomplish this goal. There is no need to check the lookahead at every character:

^(?!.*filename\.js$).*\.js$

works just as well:

^                 # Start of string
(?!               # Assert that we can't match the following:
 .*               # any string, 
  filename\.js    # followed by filename.js
  $               # and end-of-string
)                 # End of negative lookahead
.*                # Match any string
\.js              # Match .js
$                 # End of string

There are two ways to know which rules are overriding:

1. Search the property in the Filter box at the top of the Styles tab. It will show all the rules containing that property, with the property highlighted in yellow.

   

2. Look in the Computed tab to find the same property type, and then expand that to see the source of the various rules that are trying to apply that property.

   

A complementary note about CREATE TABLE .. TYPE="" syntax in SQL dump files

TLDR: If you still get CREATE TABLE ... TYPE="..." statements in SQL dump files generated by third party tools, it most certainly indicates that your server is configured to use a default sqlmode of MYSQL40 or MYSQL323.

Long story

As it was said by others, the TYPE argument to CREATE TABLE has been deprecated for a long time in MySQL. mysqldump correctly uses the ENGINE argument, unless you specifically ask it to generate a backward compatible dump (for example using --compatible=mysql40 in versions of mysqldump up to 5.7).

However, many external SQL dump tools (for example, those integrated in MySQL clients such as phpmyadmin, Navicat and DBVisualizer, as well as those used by external automated backup services such as iControlWP) are not specifically aware of this change, and instead rely on the SHOW CREATE TABLE ... command to provide table creation statements for each tables (and just to it make it clear: this is actually a good thing). However, the SHOW CREATE TABLE will actually produce outdated syntax, including the TYPE argument, if the sqlmode variable is set to MYSQL40 or MYSQL323.

Therefore, if you still get CREATE TABLE ... TYPE="..." statements in SQL dump files generated by third party tools, it most certainly indicates that your server is configured to use a default sqlmode of MYSQL40 or MYSQL323.

These sqlmodes basically configure MySQL to retain some backward compatible behaviours, and using them by default was largely recommended a few years ago. It is however highly improbable that you still have any code that wouldn't work correctly without these modes. Anyway, MYSQL40, MYSQL323 and several other similar sqlmodes have themselves been deprecated and are not supported in MySQL 8.0 and higher.

If your server is still configured with these sqlmodes and you are worried that some legacy program might fail if you change these, then one possibility is to set the sqlmode locally for that program, by executing SET SESSION sql_mode = 'MYSQL40'; immediately after connection. Note that this should only be considered as a temporary patch, and will not work in MySQL 8.0 and higher.

A more future-proof solution that do not involve rewriting your SQL queries would be to determine exactly which compatibility features need to be enable, and to enable only those, on a per-program basis (as described previously). The default sqlmode (that is, in server's configuration) should ideally be left unset (which will use official MySQL defaults for your current version). The full list of sqlmode (as of MySQL 5.7) is described here: https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html.

You can easily implement clrscr() using simple for loop printing "\b".

Of course it is an old post but just for people how will find it through search engine.

Another solution is to run it like this for IE9 and later

iexplore.exe" -noframemerging http://google.com
iexplore.exe" -noframemerging http://gmail.com

-noframemerging means run IE independently. For example it you want to run 2 browser and login as different username it will not work if you just run 2 IE. but with -noframemerging it will work. -noframemerging works for IE9 and later, for early versions like IE8 it is -nomerge

usually I create 1 but file like this run_ie.bat

"c:\Program Files (x86)\Internet Explorer\iexplore.exe" -noframemerging %1

and I create another bat file like this run_2_ie.bat

start run_ie.bat http://google.com
start run_ie.bat http://yahoo.com

You can fetch and then check out only one file in this way:

git fetch
git checkout -m <revision> <yourfilepath>
git add <yourfilepath>
git commit

Regarding the git checkout command:

• <revision> -- a branch name, i.e. origin/master
• <yourfilepath> does not include the repository name (that you can get from clicking copy path button on a file page on GitHub), i.e. README.md

The following code is perfectly fine and the right way (most exact, concise, and clear) to check if an object is null:

object obj = null;

//...

if (obj == null)
{
    // Do something
}

String.IsNullOrEmpty is a method existing for convenience so that you don't have to write the comparison code yourself:

private bool IsNullOrEmpty(string input)
{
    return input == null || input == string.Empty;
}

Additionally, there is a String.IsNullOrWhiteSpace method checking for null and whitespace characters, such as spaces, tabs etc.

Learning C forces you to think harder about some issues such as explicit and implicit memory management or storage sizes of basic data types at the time you write your code.

Once you have reached a point where you feel comfortable around C's features and misfeatures, you will probably have less trouble learning and writing in C++.

It is entirely possible that the C++ code you have seen did not look much different from standard C, but that may well be because it was not object oriented and did not use exceptions, object-orientation, templates or other advanced features.

adding org.apache.derby dependency solved my issue.

<dependency>
            <groupId>org.apache.derby</groupId>
            <artifactId>derby</artifactId>
            <scope>runtime</scope>
        </dependency>

In my understanding searching distinctive colors is related to search efficiently from an unit cube, where 3 dimensions of the cube are three vectors along red, green and blue axes. This can be simplified to search in a cylinder (HSV analogy), where you fix Saturation (S) and Value (V) and find random Hue values. It works in many cases, and see this here :

https://martin.ankerl.com/2009/12/09/how-to-create-random-colors-programmatically/

In R,

get_distinct_hues <- function(ncolor,s=0.5,v=0.95,seed=40) {
  golden_ratio_conjugate <- 0.618033988749895
  set.seed(seed)
  h <- runif(1)
  H <- vector("numeric",ncolor)
  for(i in seq_len(ncolor)) {
    h <- (h + golden_ratio_conjugate) %% 1
    H[i] <- h
  }
  hsv(H,s=s,v=v)
}

An alternative way, is to use R package "uniformly" https://cran.r-project.org/web/packages/uniformly/index.html

and this simple function can generate distinctive colors:

get_random_distinct_colors <- function(ncolor,seed = 100) {
  require(uniformly)
  set.seed(seed)
  rgb_mat <- runif_in_cube(n=ncolor,d=3,O=rep(0.5,3),r=0.5)
  rgb(r=rgb_mat[,1],g=rgb_mat[,2],b=rgb_mat[,3])
}

One can think of a little bit more involved function by grid-search:

get_random_grid_colors <- function(ncolor,seed = 100) {
  require(uniformly)
  set.seed(seed)
  ngrid <- ceiling(ncolor^(1/3))
  x <- seq(0,1,length=ngrid+1)[1:ngrid]
  dx <- (x[2] - x[1])/2
  x <- x + dx
  origins <- expand.grid(x,x,x)
  nbox <- nrow(origins) 
  RGB <- vector("numeric",nbox)
  for(i in seq_len(nbox)) {
    rgb <- runif_in_cube(n=1,d=3,O=as.numeric(origins[i,]),r=dx)
    RGB[i] <- rgb(rgb[1,1],rgb[1,2],rgb[1,3])
  }
  index <- sample(seq(1,nbox),ncolor)
  RGB[index]
} 

check this functions by:

ncolor <- 20
barplot(rep(1,ncolor),col=get_distinct_hues(ncolor))          # approach 1
barplot(rep(1,ncolor),col=get_random_distinct_colors(ncolor)) # approach 2
barplot(rep(1,ncolor),col=get_random_grid_colors(ncolor))     # approach 3

However, note that, defining a distinct palette with human perceptible colors is not simple. Which of the above approach generates diverse color set is yet to be tested.

Regarding which python version to use, Mac OS usually ships an old version of python. It's a good idea to upgrade to a newer version. You can download a .dmg from http://www.python.org/download/ . If you do that, remember to update the path. You can find the exact commands here http://farmdev.com/thoughts/66/python-3-0-on-mac-os-x-alongside-2-6-2-5-etc-/

You could use a Common Table Expression to create the SUM first, join it to the table, and then use the WHEN to to get the value from the CTE or the original table as necessary.

WITH PercentageOfTotal (Id, Percentage) 
AS 
(
    SELECT Id, (cnt / SUM(AreaId)) FROM dbo.MyTable GROUP BY Id
)
SELECT 
    CASE
        WHEN o.TotalType = 'Average' THEN r.avgscore
        WHEN o.TotalType = 'PercentOfTot' THEN pt.Percentage
        ELSE o.cnt
    END AS [displayscore]
FROM PercentageOfTotal pt
    JOIN dbo.MyTable t ON pt.Id = t.Id

I already did post this answer somewhere, i will do it here again. This version doesn't use any major inbuilt method. You got the char array, convert it into a String. Hope it helps!

import java.util.Scanner;

public class SentenceToWord 
{
    public static int getNumberOfWords(String sentence)
    {
        int counter=0;
        for(int i=0;i<sentence.length();i++)
        {
            if(sentence.charAt(i)==' ')
            counter++;
        }
        return counter+1;
    }

    public static char[] getSubString(String sentence,int start,int end) //method to give substring, replacement of String.substring() 
    {
        int counter=0;
        char charArrayToReturn[]=new char[end-start];
        for(int i=start;i<end;i++)
        {
            charArrayToReturn[counter++]=sentence.charAt(i);
        }
        return charArrayToReturn;
    }

    public static char[][] getWordsFromString(String sentence)
    {
        int wordsCounter=0;
        int spaceIndex=0;
        int length=sentence.length();
        char wordsArray[][]=new char[getNumberOfWords(sentence)][]; 
        for(int i=0;i<length;i++)
        {
            if(sentence.charAt(i)==' ' || i+1==length)
            {
            wordsArray[wordsCounter++]=getSubString(sentence, spaceIndex,i+1); //get each word as substring
            spaceIndex=i+1; //increment space index
            }
        }
        return  wordsArray; //return the 2 dimensional char array
    }


    public static void main(String[] args) 
    {
    System.out.println("Please enter the String");
    Scanner input=new Scanner(System.in);
    String userInput=input.nextLine().trim();
    int numOfWords=getNumberOfWords(userInput);
    char words[][]=new char[numOfWords+1][];
    words=getWordsFromString(userInput);
    System.out.println("Total number of words found in the String is "+(numOfWords));
    for(int i=0;i<numOfWords;i++)
    {
        System.out.println(" ");
        for(int j=0;j<words[i].length;j++)
        {
        System.out.print(words[i][j]);//print out each char one by one
        }
    }
    }

}

Try from tensorflow.python import keras

with this, you can easily change keras dependent code to tensorflow in one line change.

You can also try from tensorflow.contrib import keras. This works on tensorflow 1.3

Edited: for tensorflow 1.10 and above you can use import tensorflow.keras as keras to get keras in tensorflow.

Update:

As @Ryan Leonard pointed out correctly, my answer doesn't really fix the point I made my self... You need to both trim and remove double spaces with (for example) string.replace(/ +/g, " ").. Or you could split the el.className and then remove empty values with (for example) arr.filter(Boolean).

const classes = element.className.split(' ').filter(Boolean);

or more modern

const classes = element.classList;

Old:

With all the given answers, you should never forget to user .trim() (or $.trim())

Because classes gets added and removed, it can happen that there are multiple spaces between class string.. e.g. 'class1 class2       class3'..

This would turn into ['class1', 'class2','','','', 'class3']..

When you use trim, all multiple spaces get removed..

This message displays when Internet Explorer reaches the maximum number of synchronous instructions for a piece of JavaScript. The default maximum is 5,000,000 instructions, you can increase this number on a single machine by editing the registry.

Internet Explorer now tracks the total number of executed script statements and resets the value each time that a new script execution is started, such as from a timeout or from an event handler, for the current page with the script engine. Internet Explorer displays a "long-running script" dialog box when that value is over a threshold amount.

The only way to solve the problem for all users that might be viewing your page is to break up the number of iterations your loop performs using timers, or refactor your code so that it doesn't need to process as many instructions.

Breaking up a loop with timers is relatively straightforward:

var i=0;
(function () {
    for (; i < 6000000; i++) {
        /*
            Normal processing here
        */

        // Every 100,000 iterations, take a break
        if ( i > 0 && i % 100000 == 0) {
            // Manually increment `i` because we break
            i++;
            // Set a timer for the next iteration 
            window.setTimeout(arguments.callee);
            break;
        }
    }
})();

After trying and reading carefully, I solved it myself. Solution is to add the following line in build.gradle.

flavorDimensions "versionCode"

android { 
       compileSdkVersion 24
       .....
       flavorDimensions "versionCode"
} 

another simple approach with modern built-in stuff like PercentRelativeLayout is now available for new users who hit this problem. thanks to android team for release this item.

<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
app:layout_widthPercent="50%">

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop" />

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="#55000000"
        android:paddingBottom="15dp"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:textColor="@android:color/white" />

</FrameLayout>

and for better performance you can use some stuff like picasso image loader which help you to fill whole width of every image parents. for example in your adapter you should use this:

int width= context.getResources().getDisplayMetrics().widthPixels;
    com.squareup.picasso.Picasso
            .with(context)
            .load("some url")
            .centerCrop().resize(width/2,width/2)
            .error(R.drawable.placeholder)
            .placeholder(R.drawable.placeholder)
            .into(item.drawableId);

now you dont need CustomImageView Class anymore.

P.S i recommend to use ImageView in place of Type Int in class Item.

hope this help..

Just because java's implementation of Cloneable is broken it doesn't mean you can't create one of your own.

If OP real purpose was to create a deep clone, i think that it is possible to create an interface like this:

public interface Cloneable<T> {
    public T getClone();
}

then use the prototype constructor mentioned before to implement it:

public class AClass implements Cloneable<AClass> {
    private int value;
    public AClass(int value) {
        this.vaue = value;
    }

    protected AClass(AClass p) {
        this(p.getValue());
    }

    public int getValue() {
        return value;
    }

    public AClass getClone() {
         return new AClass(this);
    }
}

and another class with an AClass object field:

public class BClass implements Cloneable<BClass> {
    private int value;
    private AClass a;

    public BClass(int value, AClass a) {
         this.value = value;
         this.a = a;
    }

    protected BClass(BClass p) {
        this(p.getValue(), p.getA().getClone());
    }

    public int getValue() {
        return value;
    }

    public AClass getA() {
        return a;
    }

    public BClass getClone() {
         return new BClass(this);
    }
}

In this way you can easely deep clone an object of class BClass without need for @SuppressWarnings or other gimmicky code.

DISTINCT is always a right choice to get unique values. Also you can do it alternatively without using it. That's GROUP BY. Which has simply add at the end of the query and followed by the column name.

SELECT * FROM buy GROUP BY date,description

Gaa! Go to asciitable.com. The arrow keys are the control equivalent of the HJKL keys. I.e., in vi create a big block of text. Note you can move around in that text using the HJKL keys. The arrow keys are going to be ^H, ^J, ^K, ^L.

At asciitable.com find, "K" in the third column. Now, look at the same row in the first column to find the matching control-code ("VT" in this case).

Swift 4, 4.2 and 5

Remove space from front and end only

let str = "  Akbar Code  "
let trimmedString = str.trimmingCharacters(in: .whitespacesAndNewlines)

Remove spaces from every where in the string

let stringWithSpaces = " The Akbar khan code "
let stringWithoutSpaces = stringWithSpaces.replacingOccurrences(of: " ", with: "")

You either use the child selector

So using

#parent > child

Will make only the first level children to have the styles applied. Unfortunately IE6 doesn't support the child selector.

Otherwise you can use

#parent child child

To set another specific styles to children that are more than one level below.

.then(() => new Promise((resolve) => setTimeout(resolve, 15000)))

UPDATE:

when I need sleep in async function I throw in

await new Promise(resolve => setTimeout(resolve, 1000))
