Use some design patterns, you can mix UIWebView and WKWebView. The key point is to design a unique browser interface. But you should pay more attention to your app's current functionality, for example: if your app using NSURLProtocol to enhance network ability, using WKWebView you have no chance to do the same thing. Because NSURLProtocol only effects the current process, and WKWebView using muliti-process architecture, the networking staff is in a seperate process.

After inspecting the sample website you provided, I found that the author might achieve the effect by using a library called Stellar.js, take a look at the library site, cheers!

Cocos2d-x within uikit tutorial http://jpsarda.tumblr.com/post/24983791554/mixing-cocos2d-x-uikit

I had to specify individual commands first and then use the * to bring all in command.

from tkinter import filedialog
from tkinter import *

I also had the problem, hence me stumbling on this post. I added the following line of code before and after a Copy / Delete.

Delete

File.SetAttributes(file, FileAttributes.Normal);
File.Delete(file);

Copy

File.Copy(file, dest, true);
File.SetAttributes(dest, FileAttributes.Normal);

Use this XPath expression:

/*/*/X/node()

This selects any node (element, text node, comment or processing instruction) that is a child of any X element that is a grand-child of the top element of the XML document.

To verify what is selected, here is this XSLT transformation that outputs exactly the selected nodes:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>
 <xsl:template match="/">
  <xsl:copy-of select="/*/*/X/node()"/>
 </xsl:template>
</xsl:stylesheet>

and it produces exactly the wanted, correct result:

   First Text Node #1            
    <y> Y can Have Child Nodes #                
        <child> deep to it </child>
    </y>            Second Text Node #2 
    <z />

Explanation:

1. As defined in the W3 XPath 1.0 Spec, "child::node() selects all the children of the context node, whatever their node type." This means that any element, text-node, comment-node and processing-instruction node children are selected by this node-test.

2. node() is an abbreviation of child::node() (because child:: is the primary axis and is used when no axis is explicitly specified).

some times when you use android:windowSoftInputMode="stateAlwaysHidden"in manifest activity or xml, that time it will lose keyboard focus. So first check for that property in your xml and manifest,if it is there just remove it. After add these option to manifest file in side activity android:windowSoftInputMode="adjustPan"and add this property to listview in xml android:descendantFocusability="beforeDescendants"

Maybe worth looking at QRGen, which is built on top of ZXing and supports UTF-8 with this kind of syntax:

// if using special characters don't forget to supply the encoding
VCard johnSpecial = new VCard("Jöhn D?e")
                        .setAdress("ëåäö? Sträät 1, 1234 Döestüwn");
QRCode.from(johnSpecial).withCharset("UTF-8").file();

In addition to having more registers, 64-bit has SSE2 by default. This means that you can indeed perform some calculations in parallel. The SSE extensions had other goodies too. But I guess the main benefit is not having to check for the presence of the extensions. If it's x64, it has SSE2 available. ...If my memory serves me correctly.

You can also use search function without parameters:

jQuery("#id").autocomplete("search", "");

I know nothing about the Python interpreter inner workings (and I'm not an expert in compilers and interpreters either) so don't blame me if I propose anything unsensible or impossible.

Provided that python objects are mutable I think that this should be taken into account when designing the default arguments stuff. When you instantiate a list:

a = []

you expect to get a new list referenced by a.

Why should the a=[] in

def x(a=[]):

instantiate a new list on function definition and not on invocation? It's just like you're asking "if the user doesn't provide the argument then instantiate a new list and use it as if it was produced by the caller". I think this is ambiguous instead:

def x(a=datetime.datetime.now()):

user, do you want a to default to the datetime corresponding to when you're defining or executing x? In this case, as in the previous one, I'll keep the same behaviour as if the default argument "assignment" was the first instruction of the function (datetime.now() called on function invocation). On the other hand, if the user wanted the definition-time mapping he could write:

b = datetime.datetime.now()
def x(a=b):

I know, I know: that's a closure. Alternatively Python might provide a keyword to force definition-time binding:

def x(static a=b):

You can't serialize a class that implements IDictionary. Check out this link.

Q: Why can't I serialize hashtables?

A: The XmlSerializer cannot process classes implementing the IDictionary interface. This was partly due to schedule constraints and partly due to the fact that a hashtable does not have a counterpart in the XSD type system. The only solution is to implement a custom hashtable that does not implement the IDictionary interface.

So I think you need to create your own version of the Dictionary for this. Check this other question.

Do you have an entry for weddinglist in your hosts file? You can find this in:

C:\WINDOWS\system32\drivers\etc

nslookup always uses DNS whereas ping uses other methods for finding hostnames as well.

You've tagged this question with the ssl tag, and SSL is the answer. Curious.

In a KeyPress event, if the user pressed Enter, call

SendKeys.Send("{TAB}")

Nicest way to implement automatically selecting the text on receiving focus is to create a subclass of TextBox in your project with the following override:

Protected Overrides Sub OnGotFocus(ByVal e As System.EventArgs)
    SelectionStart = 0
    SelectionLength = Text.Length
    MyBase.OnGotFocus(e)
End Sub

Then use this custom TextBox in place of the WinForms standard TextBox on all your Forms.

Declaring inside the loop limits the scope of the respective variable. It all depends on the requirement of the project on the scope of the variable.

Use a Windows Package manager like chocolatey. First install chocolatey as indicated on it's homepage. That should be a breeze

Then, to install Node JS (Install), run the following command from the command line or from PowerShell:

C:> cinst nodejs.install

Following solution worked for me. When connecting to the db, specify that data should be truncated if they are too long (jdbcCompliantTruncation). My link looks like this:

jdbc:mysql://SERVER:PORT_NO/SCHEMA?sessionVariables=sql_mode='NO_ENGINE_SUBSTITUTION'&jdbcCompliantTruncation=false

If you increase the size of the strings, you may face the same problem in future if the string you are attempting to store into the DB is longer than the new size.

EDIT: STRICT_TRANS_TABLES has to be removed from sql_mode as well.

You could override the framework CSS (I guess you're using one) and set the size as you want, like this:

.pnx-msg-icon pnx-icon-msg-warning {
    width: 24px !important;
    height: 24px !important;
}

The "!important" property will make sure your code has priority to the framework's code. Make sure you are overriding the correct property, I don't know how the framework is working, this is just an example of !important usage.

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    MySqlCommand cmd;
    string id1 = GridView1.DataKeys[e.RowIndex].Value.ToString();
    con.Open();
    cmd = new MySqlCommand("delete from tableName where refno='" + id1 + "'", con);
    cmd.ExecuteNonQuery();
    con.Close();
    BindView();
}
private void BindView()
{
    GridView1.DataSource = ms.dTable("select * from table_name");
    GridView1.DataBind();
}

For converting an entire xml document to a pretty xml document
(ex: assuming you've extracted [unzipped] a LibreOffice Writer .odt or .ods file, and you want to convert the ugly "content.xml" file to a pretty one for automated git version control and git difftooling of .odt/.ods files, such as I'm implementing here)

import xml.dom.minidom

file = open("./content.xml", 'r')
xml_string = file.read()
file.close()

parsed_xml = xml.dom.minidom.parseString(xml_string)
pretty_xml_as_string = parsed_xml.toprettyxml()

file = open("./content_new.xml", 'w')
file.write(pretty_xml_as_string)
file.close()

- Thanks to Ben Noland's answer on this page which got me most of the way there.

Why not simply cast the child class to a specific parent class and invoke the specific implementation then? This is a special case situation and a special case solution should be used. You will have to use the new keyword in the children methods though.

public class SuperBase
{
    public string Speak() { return "Blah in SuperBase"; }
}

public class Base : SuperBase
{
    public new string Speak() { return "Blah in Base"; }
}

public class Child : Base
{
    public new string Speak() { return "Blah in Child"; }
}

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        Child childObj = new Child();

        Console.WriteLine(childObj.Speak());

        // casting the child to parent first and then calling Speak()
        Console.WriteLine((childObj as Base).Speak()); 

        Console.WriteLine((childObj as SuperBase).Speak());
    }
}

Note that if you rely on sleep taking exactly 50 ms, you won't get that. It will just be about it.

In "configuration file" instead this lines:

<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />

by this lines:

<compilation debug="true" targetFramework="4.0" />
<httpRuntime targetFramework="4.0" />

This error because in version 4.0 library belong to "asp:RequiredFieldValidator" exist but in version 4.5 library not exist so you need to add library by yourself

add this in web.config file

           <configuration>
              <appSettings>
                 <add key="ConnectionString" value="Your connection string which contains database id and password"/>
            </appSettings>
            </configuration>

.cs file

 public ConnectionObjects()
 {           
    string connectionstring= ConfigurationManager.AppSettings["ConnectionString"].ToString();
 }

Hope this helps.

I think there's cleaner way where you don't have to create a new webclient (and it'll work with 3rd party libraries as well)

internal static class MyWebRequestCreator
{
    private static IWebRequestCreate myCreator;

    public static IWebRequestCreate MyHttp
    {
        get
        {
            if (myCreator == null)
            {
                myCreator = new MyHttpRequestCreator();
            }
            return myCreator;
        }
    }

    private class MyHttpRequestCreator : IWebRequestCreate
    {
        public WebRequest Create(Uri uri)
        {
            var req = System.Net.WebRequest.CreateHttp(uri);
            req.CookieContainer = new CookieContainer();
            return req;
        }
    }
}

Now all you have to do is opt in for which domains you want to use this:

    WebRequest.RegisterPrefix("http://example.com/", MyWebRequestCreator.MyHttp);

That means ANY webrequest that goes to example.com will now use your custom webrequest creator, including the standard webclient. This approach means you don't have to touch all you code. You just call the register prefix once and be done with it. You can also register for "http" prefix to opt in for everything everywhere.

An option using AutoFilter

Option Explicit

Public Sub FilterOutMultiple()
    Dim ws As Worksheet, filterOut As Variant, toHide As Range

    Set ws = ActiveSheet
    If Application.WorksheetFunction.CountA(ws.Cells) = 0 Then Exit Sub 'Empty sheet

    filterOut = Split("A B C D E F G")

    Application.ScreenUpdating = False
    With ws.UsedRange.Columns("A")
        If ws.FilterMode Then .AutoFilter
       .AutoFilter Field:=1, Criteria1:=filterOut, Operator:=xlFilterValues
        With .SpecialCells(xlCellTypeVisible)
            If .CountLarge > 1 Then Set toHide = .Cells 'Remember unwanted (A, B, and C)
        End With
       .AutoFilter
        If Not toHide Is Nothing Then
            toHide.Rows.Hidden = True                   'Hide unwanted (A, B, and C)
           .Cells(1).Rows.Hidden = False                'Unhide header
        End If
    End With
    Application.ScreenUpdating = True
End Sub

The border-spacing property will work for this particular case.

table {
  border-collapse:separate; 
  border-spacing: 0 1em;
}

Reference.

This can be due to system cannot find firefox installed location on path.

Try following code, which should work.

System.setProperty("webdriver.firefox.bin","C:\\Program Files\\Mozilla Firefox\\firefox.exe"); 
System.setProperty("webdriver.gecko.driver","<location of geckodriver>\\geckodriver.exe");

That should work for you

• tab separated

  hive -e 'select * from some_table' > /home/yourfile.tsv

• comma separated

  hive -e 'select * from some_table' | sed 's/[\t]/,/g' > /home/yourfile.csv

select @currentTerm = CurrentTerm, @termID = TermID, @endDate = EndDate
    from table1
    where IsCurrent = 1

I was having this same issue, but the answer I found was different, thought someone might come across this issue, so here is my solution.

I had to whitelist 2 IPs for port 22, 80, 443, and 9418:

• 192.30.252.0/22

• 185.199.108.0/22

In case these IP's don't work, it might be because they got updated, you can find the most current ones on this page.

With C++11 the iteration syntax is simple. You still iterate over pairs, but accessing just the key is easy.

#include <iostream>
#include <map>

int main()
{
    std::map<std::string, int> myMap;

    myMap["one"] = 1;
    myMap["two"] = 2;
    myMap["three"] = 3;

    for ( const auto &myPair : myMap ) {
        std::cout << myPair.first << "\n";
    }
}

I think, it should be like this:

    class foo():
        input = get_input(__qualname__)

Whenever I run CodeIgniter in a sub directory I set the RewriteBase to it. Try setting it as /myproj/ instead of /.

How about:

In [1]: l=[1,2,3,4,3,2,5,6,7]

In [2]: [i for i,val in enumerate(l) if val==3]
Out[2]: [2, 4]

If you are using Graphql-Yoga you can use the following function:

const getRequestIpAddress = (request) => {_x000D_
    const requestIpAddress = request.request.headers['X-Forwarded-For'] || request.request.connection.remoteAddress_x000D_
    if (!requestIpAddress) return null_x000D_
_x000D_
    const ipv4 = new RegExp("(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)")_x000D_
_x000D_
    const [ipAddress] = requestIpAddress.match(ipv4)_x000D_
_x000D_
    return ipAddress_x000D_
}

You can use the # action in a form action:

<?php
    if(isset($_POST['SubmitButton'])){ // Check if form was submitted

        $input = $_POST['inputText']; // Get input text
        $message = "Success! You entered: " . $input;
    }
?>

<html>
    <body>
        <form action="#" method="post">
            <?php echo $message; ?>
            <input type="text" name="inputText"/>
            <input type="submit" name="SubmitButton"/>
        </form>
    </body>
</html>

sys.executable is not reliable if working in an embedded python environment. My suggestions is to deduce it from

import os
os.__file__

range() can only work with integers, but dividing with the / operator always results in a float value:

>>> 450 / 10
45.0
>>> range(450 / 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'float' object cannot be interpreted as an integer

Make the value an integer again:

for i in range(int(c / 10)):

or use the // floor division operator:

for i in range(c // 10):

As said @v.ladynev, it works with JDK 1.7

With Eclipse, to be able to perform a "Run As" maven install with the TLS command-line parameter, just configure the JDK you're using.

Open the dialog through Window > Preferences > Java > Installed JREs.

Then highlight the one you're using (should be a JDK, not a JRE), click on Edit. In the field "Default VM arguments", fill the value -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2. As shown below:

Clean the project (maybe optional), then re-run a maven install.

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

More info:

Date/Time Functions and Operators

datatype-datetime (Especial values).

Use like

rake db:drop db:create db:migrate db:seed

All in one line. This is faster since the environment doesn't get reloaded again and again.

db:drop - will drop database.

db:create - will create database (host/db/password will be taken from config/database.yml)

db:migrate - will run existing migrations from directory (db/migration/.rb)*.

db:seed - will run seed data possible from directory (db/migration/seed.rb)..

I usually prefer:

rake db:reset

to do all at once.

Cheers!

As .Net progresses, so does their ability to add new 32-bit configurations that trips everyone up it seems.

If you are on .Net Framework 4.7.2 do the following:

Go to Project Properties

Build

Uncheck 'prefer 32-bit'

Cheers!

In the launcher script you can force it, it permits to keep the same script and same launcher for both architecture

:: For 32 bits architecture, this line is sufficent (32bits is the only cscript available)
set CSCRIPT="cscript.exe"
:: Detect windows 64bits and use the expected cscript (SysWOW64 contains 32bits executable)
if exist "C:\Windows\SysWOW64\cscript.exe" set CSCRIPT="C:\Windows\SysWOW64\cscript.exe"
%CSCRIPT% yourscript.vbs

Just to give you another example, although range(value) is by far the best way to do this, this might help you later on something else.

list = []
calc = 0

while int(calc) < 9:
    list.append(calc)
    calc = int(calc) + 1

print list
[0, 1, 2, 3, 4, 5, 6, 7, 8]

Also, from API level 21 this is possible:

int random = ThreadLocalRandom.current().nextInt(min, max);

This way you can detect device family.

    #import <sys/utsname.h>
    NSString* deviceName()
    {
        struct utsname systemInformation;
        uname(&systemInformation);
        NSString *result = [NSString stringWithCString:systemInformation.machine
                                              encoding:NSUTF8StringEncoding];
        return result;
    }

    #define isIPhone5  [deviceName() rangeOfString:@"iPhone5,"].location != NSNotFound
    #define isIPhone5S [deviceName() rangeOfString:@"iPhone6,"].location != NSNotFound

According to Scalability and Limits section in http://dev.mysql.com/doc/refman/5.6/en/features.html, MySQL support for large databases. They use MySQL Server with databases that contain 50 million records. Some users use MySQL Server with 200,000 tables and about 5,000,000,000 rows.

On my AIX cron picks up it's environmental variables from /etc/environment ignoring what is set in the .profile.

Edit: I also checked out a couple of Linux boxes of various ages and these appear to have this file as well, so this is likely not AIX specific.

I checked this using joemaller's cron suggestion and checking the output before and after editing the PATH variable in /etc/environment.

It will overflow and wrap around to Long.MIN_VALUE.

Its not too likely though. Even if you increment 1,000,000 times per second it will take about 300,000 years to overflow.

A truly amazing list of answers, but since one pretty good one is still missing, I'll mention it here: open the csv file with google sheets and save it back to your local computer as an excel file.

In contrast to Microsoft, Google has managed to support UTF-8 csv files so it just works to open the file there. And the export to excel format also just works. So even though this may not be the preferred solution for all, it is pretty fail safe and the number of clicks is not as high as it may sound, especially when you're already logged into google anyway.

It is a public final field for the array type. You can refer to the document below:

http://java.sun.com/docs/books/jls/third_edition/html/arrays.html#10.7

You can try to do my answer,

you wrote this:

<?php
foreach($group_membership as $i => $username) {
    $items = array($username);
}

print_r($items);
?>

And in your case I would do this:

<?php
$items = array();
foreach ($group_membership as $username) { // If you need the pointer (but I don't think) you have to add '$i => ' before $username
    $items[] = $username;
} ?>

As you show in your question it seems that you need an array of usernames that are in a particular group :) In this case I prefer a good sql query with a simple while loop ;)

<?php
$query = "SELECT `username` FROM group_membership AS gm LEFT JOIN users AS u ON gm.`idUser` = u.`idUser`";
$result = mysql_query($query);
while ($record = mysql_fetch_array($result)) { \
    $items[] = $username; 
} 
?>

while is faster, but the last example is only a result of an observation. :)

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();

        if(!locale.equalsIgnoreCase("sk")) menu.findItem(R.id.action_cyclesn).setVisible(false);

        return true;
    }

As per the W3C:

Since the initial value of the border styles is 'none', no borders will be visible unless the border style is set.

In other words, you need to set a border style (e.g. solid) for the border to show up. border:thin only sets the width. Also, the color will by default be the same as the text color (which normally doesn't look good).

I recommend setting all three styles:

style="border: thin solid black"

On jenkins 2.x, with groovy plugin 2.0, running SystemGroovyScript I managed to get to build variables, as below:

def build = this.getProperty('binding').getVariable('build')
def listener = this.getProperty('binding').getVariable('listener')
def env = build.getEnvironment(listener)
println env.MY_VARIABLE

If you are using goovy from file, simple System.getenv('MY_VARIABLE') is sufficient

I successfully put a portable version of libreoffice on my host's webserver, which I call with PHP to do a commandline conversion from .docx, etc. to pdf. on the fly. I do not have admin rights on my host's webserver. Here is my blog post of what I did:

select max(Salary) from Employee 
where Salary
  not in (Select top4 salary from Employee);

because answer is as follows

max(5,6,7,8)

so 5th highest record will be displayed, first four will not be considered

This is a good solution. The best part is on the SQL side – fine tuning to any level is easy.

I used MySql and MySql Workbench to Cascade on delete for the Required Foreign KEY.

You should use Root to refer to the root element:

xmlFile.Root.Elements("Band")

If you want to find elements anywhere in the document use Descendants instead:

xmlFile.Descendants("Band")

fedorqui has a working solution but there is another way to do the same thing.

Chock if a variable is set

#!/bin/bash
amIEmpty='Hello'
# This will be true if the variable has a value
if [ $amIEmpty ]; then
    echo 'No, I am not!';
fi

Or to verify that a variable is empty

#!/bin/bash      
amIEmpty=''
# This will be true if the variable is empty
if [ ! $amIEmpty ]; then
    echo 'Yes I am!';
fi

You can use this function to determine the type of anything:

var type = function(obj) {
    return Object.prototype.toString.apply(obj).replace(/\[object (.+)\]/i, '$1').toLowerCase();
};

To check if a variable is a string:

type('my string') === 'string' //true
type(new String('my string')) === 'string' //true
type(`my string`) === 'string' //true
type(12345) === 'string' //false
type({}) === 'string' // false

https://codepen.io/patodiblasi/pen/NQXPwY?editors=0012

To check for other types:

type(null) //null
type(undefined) //undefined
type([]) //array
type({}) //object
type(function() {}) //function
type(123) //number
type(new Number(123)) //number
type(/some_regex/) //regexp
type(Symbol("foo")) //symbol

Try nStore, it seems like a nice key/value lightweight dembedded db for node. See https://github.com/creationix/nstore

Do not use eval! It has a major risk of introducing arbitrary code execution.

BashFAQ-50 - I'm trying to put a command in a variable, but the complex cases always fail.

Put it in an array and expand all the words with double-quotes "${arr[@]}" to not let the IFS split the words due to Word Splitting.

cmdArgs=()
cmdArgs=('date' '+%H:%M:%S')

and see the contents of the array inside. The declare -p allows you see the contents of the array inside with each command parameter in separate indices. If one such argument contains spaces, quoting inside while adding to the array will prevent it from getting split due to Word-Splitting.

declare -p cmdArgs
declare -a cmdArgs='([0]="date" [1]="+%H:%M:%S")'

and execute the commands as

"${cmdArgs[@]}"
23:15:18

(or) altogether use a bash function to run the command,

cmd() {
   date '+%H:%M:%S'
}

and call the function as just

cmd

POSIX sh has no arrays, so the closest you can come is to build up a list of elements in the positional parameters. Here's a POSIX sh way to run a mail program

# POSIX sh
# Usage: sendto subject address [address ...]
sendto() {
    subject=$1
    shift
    first=1
    for addr; do
        if [ "$first" = 1 ]; then set --; first=0; fi
        set -- "$@" --recipient="$addr"
    done
    if [ "$first" = 1 ]; then
        echo "usage: sendto subject address [address ...]"
        return 1
    fi
    MailTool --subject="$subject" "$@"
}

Note that this approach can only handle simple commands with no redirections. It can't handle redirections, pipelines, for/while loops, if statements, etc

Another common use case is when running curl with multiple header fields and payload. You can always define args like below and invoke curl on the expanded array content

curlArgs=('-H' "keyheader: value" '-H' "2ndkeyheader: 2ndvalue")
curl "${curlArgs[@]}"

Another example,

payload='{}'
hostURL='http://google.com'
authToken='someToken'
authHeader='Authorization:Bearer "'"$authToken"'"'

now that variables are defined, use an array to store your command args

curlCMD=(-X POST "$hostURL" --data "$payload" -H "Content-Type:application/json" -H "$authHeader")

and now do a proper quoted expansion

curl "${curlCMD[@]}"

There are many answers and all are correct as well. But unfortunately none of them have a clear explanation.

The following works for a non-primary key mapping as well.

Let's say we have parent table A with column 1 and another table, B, with column 2 which references column 1:

@ManyToOne
@JoinColumn(name = "TableBColumn", referencedColumnName = "TableAColumn")
private TableA session_UserName;

@ManyToOne
@JoinColumn(name = "bok_aut_id", referencedColumnName = "aut_id")
private Author bok_aut_id;

urlretrieve is not work for me, and the official document said that They might become deprecated at some point in the future.

import shutil 
from urllib.request import URLopener
opener = URLopener()
url = 'ftp://ftp_domain/path/to/the/file'
store_path = 'path//to//your//local//storage'
with opener.open(url) as remote_file, open(store_path, 'wb') as local_file:
    shutil.copyfileobj(remote_file, local_file)

if(!$('element').val()) {
   // code
}

Modern JavaScript:

Note that you should always use triple equals === when doing comparison in JavaScript (JS). The triple equals makes sure, that JS comparison behaves like double equals == in other languages. The following solution shows how to solve this the functional way, which will never have out of bounds error:

// Let has local scope
let array = [1, 2, 3, 5, 2, 8, 9, 2]

// Functional filter with an Arrow function
array.filter(x => x === 2).length  // -> 3

The following anonymous Arrow function (lambda function) in JavaScript:

(x) => {
   const k = 2
   return k * x
}

may be simplified to this concise form for a single input:

x => 2 * x

where the return is implied.

I think you could do it by creating parameters in an object maybe?

var myObject = {}; for(var i=0;i<myArray.length;i++) {     myObject[ myArray[i] ]; } 

If you don't set them to anything, you'll just have an object with some parameters that are undefined. I'd have to write this myself to be sure though.

bool b = list.Contains("Hello", StringComparer.CurrentCultureIgnoreCase);

[EDIT] extension code:

public static bool Contains(this string source, string cont
                                                    , StringComparison compare)
{
    return source.IndexOf(cont, compare) >= 0;
}

This could work :)

Maybe these two examples illustrate you the difference between a deadlock and a livelock:

Java-Example for a deadlock:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class DeadlockSample {

    private static final Lock lock1 = new ReentrantLock(true);
    private static final Lock lock2 = new ReentrantLock(true);

    public static void main(String[] args) {
        Thread threadA = new Thread(DeadlockSample::doA,"Thread A");
        Thread threadB = new Thread(DeadlockSample::doB,"Thread B");
        threadA.start();
        threadB.start();
    }

    public static void doA() {
        System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
        lock1.lock();
        System.out.println(Thread.currentThread().getName() + " : holds lock 1");

        try {
            System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
            lock2.lock();
            System.out.println(Thread.currentThread().getName() + " : holds lock 2");

            try {
                System.out.println(Thread.currentThread().getName() + " : critical section of doA()");
            } finally {
                lock2.unlock();
                System.out.println(Thread.currentThread().getName() + " : does not hold lock 2 any longer");
            }
        } finally {
            lock1.unlock();
            System.out.println(Thread.currentThread().getName() + " : does not hold lock 1 any longer");
        }
    }

    public static void doB() {
        System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
        lock2.lock();
        System.out.println(Thread.currentThread().getName() + " : holds lock 2");

        try {
            System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
            lock1.lock();
            System.out.println(Thread.currentThread().getName() + " : holds lock 1");

            try {
                System.out.println(Thread.currentThread().getName() + " : critical section of doB()");
            } finally {
                lock1.unlock();
                System.out.println(Thread.currentThread().getName() + " : does not hold lock 1 any longer");
            }
        } finally {
            lock2.unlock();
            System.out.println(Thread.currentThread().getName() + " : does not hold lock 2 any longer");
        }
    }
}

Sample output:

Thread A : waits for lock 1
Thread B : waits for lock 2
Thread A : holds lock 1
Thread B : holds lock 2
Thread B : waits for lock 1
Thread A : waits for lock 2

Java-Example for a livelock:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class LivelockSample {

    private static final Lock lock1 = new ReentrantLock(true);
    private static final Lock lock2 = new ReentrantLock(true);

    public static void main(String[] args) {
        Thread threadA = new Thread(LivelockSample::doA, "Thread A");
        Thread threadB = new Thread(LivelockSample::doB, "Thread B");
        threadA.start();
        threadB.start();
    }

    public static void doA() {
        try {
            while (!lock1.tryLock()) {
                System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
                Thread.sleep(100);
            }
            System.out.println(Thread.currentThread().getName() + " : holds lock 1");

            try {
                while (!lock2.tryLock()) {
                    System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
                    Thread.sleep(100);
                }
                System.out.println(Thread.currentThread().getName() + " : holds lock 2");

                try {
                    System.out.println(Thread.currentThread().getName() + " : critical section of doA()");
                } finally {
                    lock2.unlock();
                    System.out.println(Thread.currentThread().getName() + " : does not hold lock 2 any longer");
                }
            } finally {
                lock1.unlock();
                System.out.println(Thread.currentThread().getName() + " : does not hold lock 1 any longer");
            }
        } catch (InterruptedException e) {
            // can be ignored here for this sample
        }
    }

    public static void doB() {
        try {
            while (!lock2.tryLock()) {
                System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
                Thread.sleep(100);
            }
            System.out.println(Thread.currentThread().getName() + " : holds lock 2");

            try {
                while (!lock1.tryLock()) {
                    System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
                    Thread.sleep(100);
                }
                System.out.println(Thread.currentThread().getName() + " : holds lock 1");

                try {
                    System.out.println(Thread.currentThread().getName() + " : critical section of doB()");
                } finally {
                    lock1.unlock();
                    System.out.println(Thread.currentThread().getName() + " : does not hold lock 1 any longer");
                }
            } finally {
                lock2.unlock();
                System.out.println(Thread.currentThread().getName() + " : does not hold lock 2 any longer");
            }
        } catch (InterruptedException e) {
            // can be ignored here for this sample
        }
    }
}

Sample output:

Thread B : holds lock 2
Thread A : holds lock 1
Thread A : waits for lock 2
Thread B : waits for lock 1
Thread B : waits for lock 1
Thread A : waits for lock 2
Thread A : waits for lock 2
Thread B : waits for lock 1
Thread B : waits for lock 1
Thread A : waits for lock 2
Thread A : waits for lock 2
Thread B : waits for lock 1
...

Both examples force the threads to aquire the locks in different orders. While the deadlock waits for the other lock, the livelock does not really wait - it desperately tries to acquire the lock without the chance of getting it. Every try consumes CPU cycles.

Maybe you're talking about the Reverse Polish Notation? If yes you can find on wikipedia a very detailed step-to-step example for the conversion; if not I have no idea what you're asking :(

You might also want to read my answer to another question where I provided such an implementation: C++ simple operations (+,-,/,*) evaluation class

tar -cf my_archive `find ./ | grep '.php\|.html'`

Use "find" and "grep" to get all path of .php and .html files in all directory and its sub-directories. Then pass those path information to tar to compress.

Please be careful with those symbol ` and '. Note also that this will hit the limit of how many characters your shell will allow on the command line, unlike some of the other answers.

Using the -I (that's a capital i) option on the file command seems to show the file encoding.

file -I {filename}

I am not clear exactly what your situation requires but the following may get you started. The key here is using ThisWorkbook.Path to get a relative file path:

Sub SaveToRelativePath()
    Dim relativePath As String
    relativePath = ThisWorkbook.Path & Application.PathSeparator & ActiveWorkbook.Name
    ActiveWorkbook.SaveAs Filename:=relativePath
End Sub

bad_words = ['doc:', 'strickland:','\n']

with open('linetest.txt') as oldfile, open('linetestnew.txt', 'w') as newfile:
    for line in oldfile:
        if not any(bad_word in line for bad_word in bad_words):
            newfile.write(line)

The \n is a Unicode escape sequence for a newline.

{ } -->

defines scope, so if(a==1) { int b = 10; } says, you are defining int b, for {}- this scope. For

if(a==1)
  int b =10;

there is no scope. And you will not be able to use b anywhere.

I coded a function (used in Django project for DecimalField) but it can be used in Python project :

This code :

• Manage integers digits to avoid too high number
• Manage decimals digits to avoid too low number
• Manage signed and unsigned numbers

Code with tests :

def convert_decimal_to_right(value, max_digits, decimal_places, signed=True):

    integer_digits = max_digits - decimal_places
    max_value = float((10**integer_digits)-float(float(1)/float((10**decimal_places))))

    if signed:
        min_value = max_value*-1
    else:
        min_value = 0

    if value > max_value:
        value = max_value

    if value < min_value:
        value = min_value

    return round(value, decimal_places)


value = 12.12345
nb = convert_decimal_to_right(value, 4, 2)
# nb : 12.12

value = 12.126
nb = convert_decimal_to_right(value, 4, 2)
# nb : 12.13

value = 1234.123
nb = convert_decimal_to_right(value, 4, 2)
# nb : 99.99

value = -1234.123
nb = convert_decimal_to_right(value, 4, 2)
# nb : -99.99

value = -1234.123
nb = convert_decimal_to_right(value, 4, 2, signed = False)
# nb : 0

value = 12.123
nb = convert_decimal_to_right(value, 8, 4)
# nb : 12.123

you need switch into another branch and try the same.

git branch -d

Depending on the size of your list, it may be most efficient if you use list.remove() rather than create a new list:

l = ["1", "", "3", ""]

while True:
  try:
    l.remove("")
  except ValueError:
    break

This has the advantage of not creating a new list, but the disadvantage of having to search from the beginning each time, although unlike using while '' in l as proposed above, it only requires searching once per occurrence of '' (there is certainly a way to keep the best of both methods, but it is more complicated).

In case you need to perform privileged tasks like changing permissions of folders you can perform those tasks as a root user and then create a non-privileged user and switch to it:

From <some-base-image:tag>

# Switch to root user
USER root # <--- Usually you won't be needed it - Depends on base image

# Run privileged command
RUN apt install <packages>
RUN apt <privileged command>

# Set user and group
ARG user=appuser
ARG group=appuser
ARG uid=1000
ARG gid=1000
RUN groupadd -g ${gid} ${group}
RUN useradd -u ${uid} -g ${group} -s /bin/sh -m ${user} # <--- the '-m' create a user home directory

# Switch to user
USER ${uid}:${gid}

# Run non-privileged command
RUN apt <non-privileged command>

Add the following dependencies

Modify request as follows

$.ajax({ 
    url:urlName,    
    type:"POST", 
    contentType: "application/json; charset=utf-8",
    data: jsonString, //Stringified Json Object
    async: false,    //Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation
    cache: false,    //This will force requested pages not to be cached by the browser          
    processData:false, //To avoid making query String instead of JSON
    success: function(resposeJsonObject){
        // Success Message Handler
    }
});

Controller side

@RequestMapping(value = urlPattern , method = RequestMethod.POST)
public @ResponseBody Person save(@RequestBody Person jsonString) {

   Person person=personService.savedata(jsonString);
   return person;
}

@RequestBody - Covert Json object to java
@ResponseBody- convert Java object to json

Run package declaration and body separately.

this is working for me:

<td>
  <div class="avoid">
    Cell content.
  </div>
</td>
...
<style type="text/css">
  .avoid {
    page-break-inside: avoid !important;
    margin: 4px 0 4px 0;  /* to keep the page break from cutting too close to the text in the div */
  }
</style>

From this thread: avoid page break inside row of table

make copy of your original list, iterate over it, see the modified code below

for a in myarr[:]:
      if somecond(a):
          myarr.append(newObj())

You have to put your SDK's in a given directory or .app directory. You have to do it in finder while you are out of the application i'm assuming, but personally I'd use terminal in Mac instead of doing it in the App itself or finder. According to Google:

On Windows and Mac, the individual tools and other SDK packages are saved within the Android Studio application directory. To access the tools directly, use a terminal to navigate into the application and locate the sdk/ directory. For example:

 Windows: \Users\<user>\AppData\Local\Android\android-studio\sdk\
 Mac: /Applications/Android\ Studio.app/sdk/

You can use

<video src="..." ... controlsList="nodownload">

https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/controlsList

It doesn't prevent saving the video, but it does remove the download button and the "Save as" option in the context menu.

You don't have to add a . in getElementsByClassName, i.e.

var multibutton = angular.element(element.getElementsByClassName("multi-files"));

However, when using angular.element, you do have to use jquery style selectors:

angular.element('.multi-files');

should do the trick.

Also, from this documentation "If jQuery is available, angular.element is an alias for the jQuery function. If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite.""

simple using linq, change as you see fit for whatever control your dealing with.

        private void DisableButtons()
    {
        foreach (var ctl in Controls.OfType<Button>())
        {
            ctl.Enabled = false;
        }
    }

    private void EnableButtons()
    {
        foreach (var ctl in Controls.OfType<Button>())
        {
            ctl.Enabled = true;
        }
    }

You're missing a FROM and you need to give the subquery an alias.

SELECT COUNT(*) FROM 
(
  SELECT DISTINCT a.my_id, a.last_name, a.first_name, b.temp_val
   FROM dbo.Table_A AS a 
   INNER JOIN dbo.Table_B AS b 
   ON a.a_id = b.a_id
) AS subquery;

I face this problem but resolution is very simple. I am writing the 1 MB file in 1024 Byte Buffer causing this issue. To Understand refer code before and After Fix.

Code with Excepion

DataOutputStream dos = new DataOutputStream(s.getOutputStream());
        FileInputStream fis = new FileInputStream(file);
        byte[] buffer = new byte[1024];
        
        while (fis.read(buffer) > 0) {
            dos.write(buffer);
        }
    

After Fixes:

DataOutputStream dos = new DataOutputStream(s.getOutputStream());
        FileInputStream fis = new FileInputStream(file);
        byte[] buffer = new byte[102400];
        
        while (fis.read(buffer) > 0) {
            dos.write(buffer);
        }

    

If you're using RestangularV2 to post to a spring controller in java you can get this exception if you use RestangularV2.one() instead of RestangularV2.all()

On Android Studio 4.0.1, the emulator includes buttons for rotation.

In the image below, the Rotate Left (shortcut: Ctrl + Left) button is outlined in blue and the Rotate Right (shortcut: Ctrl + Right) button is outlined in red.

After pressing one of the buttons to rotate, the orientation of the application itself will not change. For instance, if we pressed Rotate Left, the application would look this:

To change the orientation of the running application, it is necessary to click the icon outlined in red above. Note that this icon may take a few seconds to show up and will disappear shortly. Also, when rotating back to portrait orientation, one must press the opposite rotate button for the icon to appear. This means that if we pressed Rotate Left, we need to press Rotate Right to return to the original orientation, and vice versa.

For case-insensitive string search, use index (or rindex) in combination with fc. This example expands on the answer by Eugene Yarmash:

use feature qw( fc ); 
my $str = "Abc"; 
my $substr = "aB"; 

print "found" if index( fc $str, fc $substr ) != -1;
# Prints: found

print "found" if rindex( fc $str, fc $substr ) != -1;
# Prints: found

$str = "Abc";
$substr = "bA";

print "found" if index( fc $str, fc $substr ) != -1;
# Prints nothing

print "found" if rindex( fc $str, fc $substr ) != -1;
# Prints nothing

Both index and rindex return -1 if the substring is not found.
And fc returns a casefolded version of its string argument, and should be used here instead of the (more familiar) uc or lc. Remember to enable this function, for example with use feature qw( fc );.

I believe the first thing you need to do is enable the package restore feature. See also here. This is done at the solution (not project) level.

But that won't get you all the way -- I ran into a similar issue after having enabled the restore feature. (VS2013, NuGet 2.8.)

It turned out I had (unintentionally) committed the packages to source control when I committed the project -- but Visual Studio (and the source control plugin) had helpfully ignored the binaries when performing the check-in.

The problem arose when I created a release branch. My local copy of the dev/main/trunk branch had the binaries, because that's where I had originally installed/downloaded the packages.
However, in the new release branch,

• the package folders and .nupkg files were all there -- so NuGet didn't think there was anything to restore;
• but at the same time, none of the DLLs were present -- i.e. the third-party references were missing -- so I couldn't build.

I deleted all the package folders in $(SolutionDir)/packages (under the release branch) and then ran a full rebuild, and this time the build succeeded.
... and then of course I went back and removed the package folders from source control (in the trunk and release branch). I'm not clear (yet) on whether the repositories.config file should be removed as well.

Many of the components installed for you by the project templates -- at least for web projects -- are NuGet packages. That is, this issue is not limited to packages you've added.
So enable package restore immediately after creating the project/solution, and before you perform an initial check-in, clear the packages folder (and make sure you commit the .nuget folder to source control).

Disclaimer: I saw another answer here on SO which indicated that clearing the packages folder was part of the resolution. That put me on the right track, so I'd like to give the author credit, but I can no longer locate that question/answer. I'll post an edit if I stumble across it.

I'd also note that Update-Package -reinstall will modify the .sln and .csproj/.vbproj files. At least that's what it did in my case. Which IMHO makes this option much less attractive.

When doing a getObject() from the S3 API, per the docs the contents of your file are located in the Body property, which you can see from your sample output. You should have code that looks something like the following

const aws = require('aws-sdk');
const s3 = new aws.S3(); // Pass in opts to S3 if necessary

var getParams = {
    Bucket: 'abc', // your bucket name,
    Key: 'abc.txt' // path to the object you're looking for
}

s3.getObject(getParams, function(err, data) {
    // Handle any error and exit
    if (err)
        return err;

  // No error happened
  // Convert Body from a Buffer to a String

  let objectData = data.Body.toString('utf-8'); // Use the encoding necessary
});

You may not need to create a new buffer from the data.Body object but if you need you can use the sample above to achieve that.

In Java class :-

    toolbar = (Toolbar) findViewById(R.id.apptool_bar);
    setSupportActionBar(toolbar);

    getSupportActionBar().setTitle("Snapdeal");

    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

In Manifest :-

<activity
            android:name=".SubActivity"
            android:label="@string/title_activity_sub"
            android:theme="@style/AppTheme" >
            <meta-data android:name="android.support.PARENT_ACTIVITY" android:value=".MainActivity"></meta-data>
    </activity>

XAMPP Apache + MariaDB + PHP + Perl (X -any OS)

• After successful installation execute xampp-control.exe in XAMPP folder

• Start Apache and MySQL

• Open browser and in url type localhost or 127.0.0.1

• then you are welcomed with dashboard

By default your port is listing with 80.If you want you can change it to your desired port number in httpd.conf file.(If port 80 is already using with other app then you have to change it).

For example you changed port number 80 to 8090 then you can run as 'localhost:8090' or '127.0.0.1:8090'

use this:

this.permissionChanged = function (obj, event) {

    if (event.type != "load") {

    } 
}

If you have the column and the sequence, you first need to populate a new key for all the existing rows. Assuming you don't care which key is assigned to which row

UPDATE table_name
   SET new_pk_column = sequence_name.nextval;

Once that's done, you can create the primary key constraint (this assumes that either there is no existing primary key constraint or that you have already dropped the existing primary key constraint)

ALTER TABLE table_name
  ADD CONSTRAINT pk_table_name PRIMARY KEY( new_pk_column )

If you want to generate the key automatically, you'd need to add a trigger

CREATE TRIGGER trigger_name
  BEFORE INSERT ON table_name
  FOR EACH ROW
BEGIN
  :new.new_pk_column := sequence_name.nextval;
END;

If you are on an older version of Oracle, the syntax is a bit more cumbersome

CREATE TRIGGER trigger_name
  BEFORE INSERT ON table_name
  FOR EACH ROW
BEGIN
  SELECT sequence_name.nextval
    INTO :new.new_pk_column
    FROM dual;
END;

JFrame and JApplet are top level containers. If you wish to create a desktop application, you will use JFrame and if you plan to host your application in browser you will use JApplet.

JComponent is an abstract class for all Swing components and you can use it as the base class for your new component. JPanel is a simple usable component you can use for almost anything.

Since this is for a fun project, the simplest way for you is to work with JPanel and then host it inside JFrame or JApplet. Netbeans has a visual designer for Swing with simple examples.

You can use the slurp module to fetch a file from the remote host: (Thanks to @mlissner for suggesting it)

vars:
  amazon_linux_ami: "ami-fb8e9292"
  user_data_file: "base-ami-userdata.sh"
tasks:
- name: Load data
  slurp:
    src: "{{ user_data_file }}"
  register: slurped_user_data
- name: Decode data and store as fact # You can skip this if you want to use the right hand side directly...
  set_fact:
    user_data: "{{ slurped_user_data.content | b64decode }}"

I was having a hard time finding a way to actually separate the dollar amount and the amount after the decimal. I think I figured it out mostly and thought to share if any of yall were having trouble

So basically...

if price is 1234.44... whole would be 1234 and decimal would be 44 or

if price is 1234.01... whole would be 1234 and decimal would be 01 or

if price is 1234.10... whole would be 1234 and decimal would be 10

and so forth

$price = 1234.44;

$whole = intval($price); // 1234
$decimal1 = $price - $whole; // 0.44000000000005 uh oh! that's why it needs... (see next line)
$decimal2 = round($decimal1, 2); // 0.44 this will round off the excess numbers
$decimal = substr($decimal2, 2); // 44 this removed the first 2 characters

if ($decimal == 1) { $decimal = 10; } // Michel's warning is correct...
if ($decimal == 2) { $decimal = 20; } // if the price is 1234.10... the decimal will be 1...
if ($decimal == 3) { $decimal = 30; } // so make sure to add these rules too
if ($decimal == 4) { $decimal = 40; }
if ($decimal == 5) { $decimal = 50; }
if ($decimal == 6) { $decimal = 60; }
if ($decimal == 7) { $decimal = 70; }
if ($decimal == 8) { $decimal = 80; }
if ($decimal == 9) { $decimal = 90; }

echo 'The dollar amount is ' . $whole . ' and the decimal amount is ' . $decimal;

In JSFiddle, when you set the wrapping to "onLoad" or "onDomready", the functions you define are only defined inside that block, and cannot be accessed by outside event handlers.

Easiest fix is to change:

function something(...)

To:

window.something = function(...)

Use a SQL DATA READER:

In this example i use a List instead an array.

try
{
    SqlCommand comm = new SqlCommand("SELECT CategoryID, CategoryName FROM Categories;",connection);
    connection.Open();

    SqlDataReader reader = comm.ExecuteReader();
    List<string> str = new List<string>();
    int i=0;
    while (reader.Read())
    {
        str.Add( reader.GetValue(i).ToString() );
        i++;
    }
    reader.Close();
}
catch (Exception)
{
    throw;
}
finally
{
    connection.Close();
}

fyi The code I ended up with:

IF UPDATE (QtyToRepair)
    begin
        INSERT INTO tmpQtyToRepairChanges (OrderNo, PartNumber, ModifiedDate, ModifiedUser, ModifiedHost, QtyToRepairOld, QtyToRepairNew)
        SELECT S.OrderNo, S.PartNumber, GETDATE(), SUSER_NAME(), HOST_NAME(), D.QtyToRepair, I.QtyToRepair FROM SCHEDULE S
        INNER JOIN Inserted I ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
        INNER JOIN Deleted D ON S.OrderNo = D.OrderNo and S.PartNumber = D.PartNumber 
        WHERE I.QtyToRepair <> D.QtyToRepair
end

Actually I tried a lot of things to make it work on Win7, since changing the SSH exectun fron native to build-it and backwards and the same error. By chance, i change it to HTTPS in the ".git/config" file as:

[remote "origin"]
        url = https://github.com/user_name/repository_name.git
        fetch = +refs/heads/*:refs/remotes/origin/*

and it finally worked. So maybe it could work for you as well.

With newer releases of jquery (1.3+ I think), all you have to do is set one of the members of the radio set to be required and jquery will take care of the rest:

<input type="radio" name="myoptions" value="blue" class="required"> Blue<br />
<input type="radio" name="myoptions" value="red"> Red<br />
<input type="radio" name="myoptions" value="green"> Green

The above would require at least 1 of the 3 radio options w/ the name of "my options" to be selected before proceeding.

The label suggestion by Mahes, btw, works wonderfully!

I found an answer here well practiced, but it was still necessary to add a delay

Create the following directive:

angular.module('MyApp').directive('emitLastRepeaterElement', function() {
return function(scope) {
    if (scope.$last){
        scope.$emit('LastRepeaterElement');
    }
}; });

Add it to your repeater as an attribute, like this:

<div ng-repeat="item in items" emit-last-repeater-element></div>

According to Radu,:

$scope.eventoSelecionado.internamento_evolucoes.forEach(ie => {mycode});

For me it works, but I still need to add a setTimeout

$scope.eventoSelecionado.internamento_evolucoes.forEach(ie => {
setTimeout(function() { 
    mycode
}, 100); });

The best solution is probably: use Modernizr.

However, if you necessarily want to use $.browser property, you can do it using jQuery Migrate plugin (for JQuery >= 1.9 - in earlier versions you can just use it) and then do something like:

if($.browser.chrome) {
   alert(1);
} else if ($.browser.mozilla) {
   alert(2);
} else if ($.browser.msie) {
   alert(3);
}

And if you need for some reason to use navigator.userAgent, then it would be:

$.browser.msie = /msie/.test(navigator.userAgent.toLowerCase()); 
$.browser.mozilla = /firefox/.test(navigator.userAgent.toLowerCase()); 

In addition to what @berguiga-mohamed-amine stated, I just found that a wildcard requires leaving the module argument the empty string:

compile ("com.github.jsonld-java:jsonld-java:$jsonldJavaVersion") {
    exclude group: 'org.apache.httpcomponents', module: ''
    exclude group: 'org.slf4j', module: ''
}

This way worked for me:

adding the path that you like:

export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add

checking: you can run 'export' cmd and check the output or you can check it using this cmd:

python -c "import sys; print(sys.path)"

You can either use the == operator or the Object.equals(Object) method.

The == operator checks whether the two subjects are the same object, whereas the equals method checks for equal contents (length and characters).

if(objectA == objectB) {
   // objects are the same instance. i.e. compare two memory addresses against each other.
}

if(objectA.equals(objectB)) {
   // objects have the same contents. i.e. compare all characters to each other 
}

Which you choose depends on your logic - use == if you can and equals if you do not care about performance, it is quite fast anyhow.

String.intern() If you have two strings, you can internate them, i.e. make the JVM create a String pool and returning to you the instance equal to the pool instance (by calling String.intern()). This means that if you have two Strings, you can call String.intern() on both and then use the == operator. String.intern() is however expensive, and should only be used as an optimalization - it only pays off for multiple comparisons.

All in-code Strings are however already internated, so if you are not creating new Strings, you are free to use the == operator. In general, you are pretty safe (and fast) with

if(objectA == objectB || objectA.equals(objectB)) {

}

if you have a mix of the two scenarios. The inline

if(objectA == null ? objectB == null : objectA.equals(objectB)) {

}

can also be quite useful, it also handles null values since String.equals(..) checks for null.

You can use the @RestController instead of @Controller annotation.

You had a mistake on the statement below. Use . not ,

echo '<img src="', $dir, '/', $file, '" alt="', $file, $

to

echo '<img src="'. $dir. '/'. $file. '" alt="'. $file. $

and

echo 'Directory \'', $dir, '\' not found!';

to

echo 'Directory \''. $dir. '\' not found!';

I too got the same error, problem in my case is I included the column name in GROUP BY clause and it caused this error. So removed the column from GROUP BY clause and it worked!!!

You can use imshow() method from matplotlib

import pandas as pd
import matplotlib.pyplot as plt
plt.style.use('ggplot')

plt.imshow(X.corr(), cmap=plt.cm.Reds, interpolation='nearest')
plt.colorbar()
tick_marks = [i for i in range(len(X.columns))]
plt.xticks(tick_marks, X.columns, rotation='vertical')
plt.yticks(tick_marks, X.columns)
plt.show()

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

The easiest way to get first day(Monday) of current week is:

strtotime("next Monday") - 604800;

where 604800 - is count of seconds in 1 week(60*60*24*7).

This code get next Monday and decrease it for 1 week. This code will work well in any day of week. Even if today is Monday.

simply do

int a = ch

(also this has nothing to do with android)

to use parameters in aliases, i use this method:

alias myalias='function __myalias() { echo "Hello $*"; unset -f __myalias; }; __myalias'

its a self-destructive function wrapped in an alias, so it pretty much is the best of both worlds, and doesnt take up an extra line(s) in your definitions... which i hate, oh yeah and if you need that return value, you'll have to store it before calling unset, and then return the value using the "return" keyword in that self destructive function there:

alias myalias='function __myalias() { echo "Hello $*"; myresult=$?; unset -f __myalias; return $myresult; }; __myalias'

so..

you could, if you need to have that variable in there

alias mongodb='function __mongodb() { ./path/to/mongodb/$1; unset -f __mongodb; }; __mongodb'

of course...

alias mongodb='./path/to/mongodb/'

would actually do the same thing without the need for parameters, but like i said, if you wanted or needed them for some reason (for example, you needed $2 instead of $1), you would need to use a wrapper like that. If it is bigger than one line you might consider just writing a function outright since it would become more of an eyesore as it grew larger. Functions are great since you get all the perks that functions give (see completion, traps, bind, etc for the goodies that functions can provide, in the bash manpage).

I hope that helps you out :)

For Swift 5.0

I used this code to copy images to photo albums my application had created; When I want to copy images files I call "startSavingPhotoAlbume()" function. First I get UIImage from App folder then save it to photo albums. Because it is irrelevant I dont show how to read image from App folder.

var saveToPhotoAlbumCounter = 0



func startSavingPhotoAlbume(){
    saveToPhotoAlbumCounter = 0
    saveToPhotoAlbume()
}

func saveToPhotoAlbume(){  
    let image = loadImageFile(fileName: imagefileList[saveToPhotoAlbumCounter], folderName: folderName)
    UIImageWriteToSavedPhotosAlbum(image!, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
}

@objc func image(_ image: UIImage, didFinishSavingWithError error: NSError?, contextInfo: UnsafeRawPointer) {
    if (error != nil) {
        print("ptoto albume savin error for \(imageFileList[saveToPhotoAlbumCounter])")
    } else {
        
        if saveToPhotoAlbumCounter < imageFileList.count - 1 {
            saveToPhotoAlbumCounter += 1
            saveToPhotoAlbume()
        } else {
            print("saveToPhotoAlbume is finished with \(saveToPhotoAlbumCounter) files")
        }
    }
}

You can use the command:

grep --color='auto' -P -n "[\x80-\xFF]" file.xml

This will give you the line number, and will highlight non-ascii chars in red.

In some systems, depending on your settings, the above will not work, so you can grep by the inverse

grep --color='auto' -P -n "[^\x00-\x7F]" file.xml

Note also, that the important bit is the -P flag which equates to --perl-regexp: so it will interpret your pattern as a Perl regular expression. It also says that

this is highly experimental and grep -P may warn of unimplemented features.

You can also do like this-

 std::map<char, int>::iterator it = m.find('c'); 
 if (it != m.end())
 (*it).second = 42;

Let's get one thing out of the way first. The explanation that yield from g is equivalent to for v in g: yield v does not even begin to do justice to what yield from is all about. Because, let's face it, if all yield from does is expand the for loop, then it does not warrant adding yield from to the language and preclude a whole bunch of new features from being implemented in Python 2.x.

What yield from does is it establishes a transparent bidirectional connection between the caller and the sub-generator:

• The connection is "transparent" in the sense that it will propagate everything correctly too, not just the elements being generated (e.g. exceptions are propagated).

• The connection is "bidirectional" in the sense that data can be both sent from and to a generator.

(If we were talking about TCP, yield from g might mean "now temporarily disconnect my client's socket and reconnect it to this other server socket".)

BTW, if you are not sure what sending data to a generator even means, you need to drop everything and read about coroutines first—they're very useful (contrast them with subroutines), but unfortunately lesser-known in Python. Dave Beazley's Curious Course on Coroutines is an excellent start. Read slides 24-33 for a quick primer.

Reading data from a generator using yield from

def reader():
    """A generator that fakes a read from a file, socket, etc."""
    for i in range(4):
        yield '<< %s' % i

def reader_wrapper(g):
    # Manually iterate over data produced by reader
    for v in g:
        yield v

wrap = reader_wrapper(reader())
for i in wrap:
    print(i)

# Result
<< 0
<< 1
<< 2
<< 3

Instead of manually iterating over reader(), we can just yield from it.

def reader_wrapper(g):
    yield from g

That works, and we eliminated one line of code. And probably the intent is a little bit clearer (or not). But nothing life changing.

Sending data to a generator (coroutine) using yield from - Part 1

Now let's do something more interesting. Let's create a coroutine called writer that accepts data sent to it and writes to a socket, fd, etc.

def writer():
    """A coroutine that writes data *sent* to it to fd, socket, etc."""
    while True:
        w = (yield)
        print('>> ', w)

Now the question is, how should the wrapper function handle sending data to the writer, so that any data that is sent to the wrapper is transparently sent to the writer()?

def writer_wrapper(coro):
    # TBD
    pass

w = writer()
wrap = writer_wrapper(w)
wrap.send(None)  # "prime" the coroutine
for i in range(4):
    wrap.send(i)

# Expected result
>>  0
>>  1
>>  2
>>  3

The wrapper needs to accept the data that is sent to it (obviously) and should also handle the StopIteration when the for loop is exhausted. Evidently just doing for x in coro: yield x won't do. Here is a version that works.

def writer_wrapper(coro):
    coro.send(None)  # prime the coro
    while True:
        try:
            x = (yield)  # Capture the value that's sent
            coro.send(x)  # and pass it to the writer
        except StopIteration:
            pass

Or, we could do this.

def writer_wrapper(coro):
    yield from coro

That saves 6 lines of code, make it much much more readable and it just works. Magic!

Sending data to a generator yield from - Part 2 - Exception handling

Let's make it more complicated. What if our writer needs to handle exceptions? Let's say the writer handles a SpamException and it prints *** if it encounters one.

class SpamException(Exception):
    pass

def writer():
    while True:
        try:
            w = (yield)
        except SpamException:
            print('***')
        else:
            print('>> ', w)

What if we don't change writer_wrapper? Does it work? Let's try

# writer_wrapper same as above

w = writer()
wrap = writer_wrapper(w)
wrap.send(None)  # "prime" the coroutine
for i in [0, 1, 2, 'spam', 4]:
    if i == 'spam':
        wrap.throw(SpamException)
    else:
        wrap.send(i)

# Expected Result
>>  0
>>  1
>>  2
***
>>  4

# Actual Result
>>  0
>>  1
>>  2
Traceback (most recent call last):
  ... redacted ...
  File ... in writer_wrapper
    x = (yield)
__main__.SpamException

Um, it's not working because x = (yield) just raises the exception and everything comes to a crashing halt. Let's make it work, but manually handling exceptions and sending them or throwing them into the sub-generator (writer)

def writer_wrapper(coro):
    """Works. Manually catches exceptions and throws them"""
    coro.send(None)  # prime the coro
    while True:
        try:
            try:
                x = (yield)
            except Exception as e:   # This catches the SpamException
                coro.throw(e)
            else:
                coro.send(x)
        except StopIteration:
            pass

This works.

# Result
>>  0
>>  1
>>  2
***
>>  4

But so does this!

def writer_wrapper(coro):
    yield from coro

The yield from transparently handles sending the values or throwing values into the sub-generator.

This still does not cover all the corner cases though. What happens if the outer generator is closed? What about the case when the sub-generator returns a value (yes, in Python 3.3+, generators can return values), how should the return value be propagated? That yield from transparently handles all the corner cases is really impressive. yield from just magically works and handles all those cases.

I personally feel yield from is a poor keyword choice because it does not make the two-way nature apparent. There were other keywords proposed (like delegate but were rejected because adding a new keyword to the language is much more difficult than combining existing ones.

In summary, it's best to think of yield from as a transparent two way channel between the caller and the sub-generator.

<input type="name" placeholder="First Name" title="First Name" />

title="First Name" solves my proble. it worked with bootstrap.

You can pass this when you call the function

<button onclick="doSomething('param',this)" id="id_button">action</button>

<script>
    function doSomething(param,me){

    var source = me
    console.log(source);
}
</script>

Here are some:

"Ali".eql? "Ali"
=> true

The spaceship (<=>) method can be used to compare two strings in relation to their alphabetical ranking. The <=> method returns 0 if the strings are identical, -1 if the left hand string is less than the right hand string, and 1 if it is greater:

"Apples" <=> "Apples"
=> 0

"Apples" <=> "Pears"
=> -1

"Pears" <=> "Apples"
=> 1

A case insensitive comparison may be performed using the casecmp method which returns the same values as the <=> method described above:

"Apples".casecmp "apples"
=> 0

^((http(s?)\:\/\/|~/|/)?([\w]+:\w+@)?([a-zA-Z]{1}([\w\-]+\.)+([\w]{2,5}))(:[\d]{1,5})?((/?\w+/)+|/?)(\w+\.(jpg|png|gif))

Is this what you're looking for? You place you CSS between style tags in the HTML document header. I'm guessing for iPhone it's webkit so it should work.

<html>
<head>
    <style type="text/css">
    .title { color: blue; text-decoration: bold; text-size: 1em; }
    .author { color: gray; }

    <span class="title">La super bonne</span>
    <span class="author">proposée par Jérém</span>

I have encountered similar mistakes, and later found that my password is wrong.

Actually, this is a duplicate of Encrypt Password in Configuration Files?.

The best solution I found so far is in this answert: https://stackoverflow.com/a/1133815/1549977

Pros: Password is saved a a char array, not as a string. It's still not good, but better than anything else.

Quick answer, this eval work:

eval('var obj = {"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}')

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants (except when using prepared statements).

With two arguments, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return. The offset of the initial row is 0 (not 1):

SELECT * FROM tbl LIMIT 5,10; # Retrieve rows 6-15

To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:

SELECT * FROM tbl LIMIT 95,18446744073709551615;

With one argument, the value specifies the number of rows to return from the beginning of the result set:

SELECT * FROM tbl LIMIT 5; # Retrieve first 5 rows

In other words, LIMIT row_count is equivalent to LIMIT 0, row_count.

In their book The Practice of Programming (which is well worth reading), Kernighan and Pike discuss this problem, and they solve it by using snprintf() to create the string with the correct buffer size for passing to the scanf() family of functions. In effect:

int scanner(const char *data, char *buffer, size_t buflen)
{
    char format[32];
    if (buflen == 0)
        return 0;
    snprintf(format, sizeof(format), "%%%ds", (int)(buflen-1));
    return sscanf(data, format, buffer);
}

Note, this still limits the input to the size provided as 'buffer'. If you need more space, then you have to do memory allocation, or use a non-standard library function that does the memory allocation for you.

Note that the POSIX 2008 (2013) version of the scanf() family of functions supports a format modifier m (an assignment-allocation character) for string inputs (%s, %c, %[). Instead of taking a char * argument, it takes a char ** argument, and it allocates the necessary space for the value it reads:

char *buffer = 0;
if (sscanf(data, "%ms", &buffer) == 1)
{
    printf("String is: <<%s>>\n", buffer);
    free(buffer);
}

If the sscanf() function fails to satisfy all the conversion specifications, then all the memory it allocated for %ms-like conversions is freed before the function returns.

You need to escape your quotes.

You can do this:

echo "<script type=\"text/javascript\">";

or this:

echo "<script type='text/javascript'>";

or this:

echo '<script type="text/javascript">';

Or just stay out of php

<script type="text/javascript">

Instead of using the outrageously convoluted data structures required by ggplot2, you can use the native R functions:

tab<-read.delim(text="

Company1 300 350
Company2 320 430
Company3 310 420
",as.is=TRUE,sep=" ",row.names=1)

tab<-t(tab)

plot(tab[,1],type="b",ylim=c(min(tab),max(tab)),col="red",lty=1,ylab="Value",lwd=2,xlab="Year",xaxt="n")
lines(tab[,2],type="b",col="black",lty=2,lwd=2)
lines(tab[,3],type="b",col="blue",lty=3,lwd=2)
grid()
legend("topleft",legend=colnames(tab),lty=c(1,2,3),col=c("red","black","blue"),bg="white",lwd=2)
axis(1,at=c(1:nrow(tab)),labels=rownames(tab))

     WakeLock screenLock =    ((PowerManager)getSystemService(POWER_SERVICE)).newWakeLock(
    PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
    screenLock.acquire();

  //later
  screenLock.release();

From a user experience stand-point, you don't want a major action to be done passively.

Something major like a window close should be the result of an action by the user.

If we take the problem as "how to make singleton with state", then it is not necessary to pass the state as constructor parameter. I agree with the posts that initialize the states or using set method after getting the singleton instance.

Another question is: is it good to have singleton with state?

It's the first result on Google: http://docs.python.org/library/stdtypes.html#string-formatting

See also the new format() function: http://docs.python.org/library/stdtypes.html#str.format

The ideal way is not to use ioutil.ReadAll, but rather use a decoder on the reader directly. Here's a nice function that gets a url and decodes its response onto a target structure.

var myClient = &http.Client{Timeout: 10 * time.Second}

func getJson(url string, target interface{}) error {
    r, err := myClient.Get(url)
    if err != nil {
        return err
    }
    defer r.Body.Close()

    return json.NewDecoder(r.Body).Decode(target)
}

Example use:

type Foo struct {
    Bar string
}

func main() {
    foo1 := new(Foo) // or &Foo{}
    getJson("http://example.com", foo1)
    println(foo1.Bar)

    // alternately:

    foo2 := Foo{}
    getJson("http://example.com", &foo2)
    println(foo2.Bar)
}

You should not be using the default *http.Client structure in production as this answer originally demonstrated! (Which is what http.Get/etc call to). The reason is that the default client has no timeout set; if the remote server is unresponsive, you're going to have a bad day.

You can use the arithmetic operators to do relative time.

Time.now - 2.days 

Will give you 2 days ago.

There are three options:

1. Chain exclude and filter

   results = Model.objects.exclude(a=True).filter(x=5)
   

2. Use Q() objects and the ~ operator

   from django.db.models import Q
   object_list = QuerySet.filter(~Q(a=True), x=5)
   

3. Register a custom lookup function

   from django.db.models import Lookup
   from django.db.models import Field
   
   @Field.register_lookup
   class NotEqual(Lookup):
       lookup_name = 'ne'
   
       def as_sql(self, compiler, connection):
           lhs, lhs_params = self.process_lhs(compiler, connection)
           rhs, rhs_params = self.process_rhs(compiler, connection)
           params = lhs_params + rhs_params
           return '%s <> %s' % (lhs, rhs), params
   

   Which can the be used as usual:

   results = Model.objects.exclude(a=True, x__ne=5)
   

This solution work on my case i am using ubuntu 16.04, VirtualBox 2.7.2 and genymotion 2.7.2 Same error come in my system i have followed simple step and my problem was solve

1. $ LD_LIBRARY_PATH=/usr/local/lib64/:$LD_LIBRARY_PATH
2. $ export LD_LIBRARY_PATH
3. $ sudo apt-add-repository ppa:ubuntu-toolchain-r/test
4. $ sudo apt-get update
5. $ sudo apt-get install gcc-4.9 g++-4.9

I hope this will work for you

Hope this piece of code give you an idea of changing jPanels inside a JFrame.

public class PanelTest extends JFrame {

        Container contentPane;

        public PanelTest()  {
           super("Changing JPanel inside a JFrame");
           contentPane=getContentPane();
        }

        public void createChangePanel() {
           contentPane.removeAll();
           JPanel newPanel=new JPanel();
           contentPane.add(newPanel);
           System.out.println("new panel created");//for debugging purposes
           validate();
           setVisible(true);
        }
}

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.

Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$

How you can use regular expressions depends on the version of iOS you are using.

iOS 4.x and Later

You can use NSRegularExpression, which allows you to compile and test against a regular expression directly.

iOS 3.x

Does not include the NSRegularExpression class, but does include NSPredicate, which can match against regular expressions.

NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];

Read a full article about this approach at cocoawithlove.com.

iOS 2.x

Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.

Here is a generic working solution based on @Beta's

I'm using GNU Make 4.1 with SHELL=/bin/bash atop my Makefile, so YMMV!

This allows us to accept extra arguments (by doing nothing when we get a job that doesn't match, rather than throwing an error).

%:
    @:

And this is a macro which gets the args for us:

args = `arg="$(filter-out $@,$(MAKECMDGOALS))" && echo $${arg:-${1}}`

Here is a job which might call this one:

test:
    @echo $(call args,defaultstring)

The result would be:

$ make test
defaultstring
$ make test hi
hi

Note! You might be better off using a "Taskfile", which is a bash pattern that works similarly to make, only without the nuances of Maketools. See https://github.com/adriancooney/Taskfile

Calling a generic method with a type parameter known only at runtime can be greatly simplified by using a dynamic type instead of the reflection API.

To use this technique the type must be known from the actual object (not just an instance of the Type class). Otherwise, you have to create an object of that type or use the standard reflection API solution. You can create an object by using the Activator.CreateInstance method.

If you want to call a generic method, that in "normal" usage would have had its type inferred, then it simply comes to casting the object of unknown type to dynamic. Here's an example:

class Alpha { }
class Beta { }
class Service
{
    public void Process<T>(T item)
    {
        Console.WriteLine("item.GetType(): " + item.GetType()
                          + "\ttypeof(T): " + typeof(T));
    }
}

class Program
{
    static void Main(string[] args)
    {
        var a = new Alpha();
        var b = new Beta();

        var service = new Service();
        service.Process(a); // Same as "service.Process<Alpha>(a)"
        service.Process(b); // Same as "service.Process<Beta>(b)"

        var objects = new object[] { a, b };
        foreach (var o in objects)
        {
            service.Process(o); // Same as "service.Process<object>(o)"
        }
        foreach (var o in objects)
        {
            dynamic dynObj = o;
            service.Process(dynObj); // Or write "service.Process((dynamic)o)"
        }
    }
}

And here's the output of this program:

item.GetType(): Alpha    typeof(T): Alpha
item.GetType(): Beta     typeof(T): Beta
item.GetType(): Alpha    typeof(T): System.Object
item.GetType(): Beta     typeof(T): System.Object
item.GetType(): Alpha    typeof(T): Alpha
item.GetType(): Beta     typeof(T): Beta

Process is a generic instance method that writes the real type of the passed argument (by using the GetType() method) and the type of the generic parameter (by using typeof operator).

By casting the object argument to dynamic type we deferred providing the type parameter until runtime. When the Process method is called with the dynamic argument then the compiler doesn't care about the type of this argument. The compiler generates code that at runtime checks the real types of passed arguments (by using reflection) and choose the best method to call. Here there is only this one generic method, so it's invoked with a proper type parameter.

In this example, the output is the same as if you wrote:

foreach (var o in objects)
{
    MethodInfo method = typeof(Service).GetMethod("Process");
    MethodInfo generic = method.MakeGenericMethod(o.GetType());
    generic.Invoke(service, new object[] { o });
}

The version with a dynamic type is definitely shorter and easier to write. You also shouldn't worry about performance of calling this function multiple times. The next call with arguments of the same type should be faster thanks to the caching mechanism in DLR. Of course, you can write code that cache invoked delegates, but by using the dynamic type you get this behaviour for free.

If the generic method you want to call don't have an argument of a parametrized type (so its type parameter can't be inferred) then you can wrap the invocation of the generic method in a helper method like in the following example:

class Program
{
    static void Main(string[] args)
    {
        object obj = new Alpha();

        Helper((dynamic)obj);
    }

    public static void Helper<T>(T obj)
    {
        GenericMethod<T>();
    }

    public static void GenericMethod<T>()
    {
        Console.WriteLine("GenericMethod<" + typeof(T) + ">");
    }
}

Increased type safety

What is really great about using dynamic object as a replacement for using reflection API is that you only lose compile time checking of this particular type that you don't know until runtime. Other arguments and the name of the method are staticly analysed by the compiler as usual. If you remove or add more arguments, change their types or rename method name then you'll get a compile-time error. This won't happen if you provide the method name as a string in Type.GetMethod and arguments as the objects array in MethodInfo.Invoke.

Below is a simple example that illustrates how some errors can be caught at compile time (commented code) and other at runtime. It also shows how the DLR tries to resolve which method to call.

interface IItem { }
class FooItem : IItem { }
class BarItem : IItem { }
class Alpha { }

class Program
{
    static void Main(string[] args)
    {
        var objects = new object[] { new FooItem(), new BarItem(), new Alpha() };
        for (int i = 0; i < objects.Length; i++)
        {
            ProcessItem((dynamic)objects[i], "test" + i, i);

            //ProcesItm((dynamic)objects[i], "test" + i, i);
            //compiler error: The name 'ProcesItm' does not
            //exist in the current context

            //ProcessItem((dynamic)objects[i], "test" + i);
            //error: No overload for method 'ProcessItem' takes 2 arguments
        }
    }

    static string ProcessItem<T>(T item, string text, int number)
        where T : IItem
    {
        Console.WriteLine("Generic ProcessItem<{0}>, text {1}, number:{2}",
                          typeof(T), text, number);
        return "OK";
    }
    static void ProcessItem(BarItem item, string text, int number)
    {
        Console.WriteLine("ProcessItem with Bar, " + text + ", " + number);
    }
}

Here we again execute some method by casting the argument to the dynamic type. Only verification of first argument's type is postponed to runtime. You will get a compiler error if the name of the method you're calling doesn't exist or if other arguments are invalid (wrong number of arguments or wrong types).

When you pass the dynamic argument to a method then this call is lately bound. Method overload resolution happens at runtime and tries to choose the best overload. So if you invoke the ProcessItem method with an object of BarItem type then you'll actually call the non-generic method, because it is a better match for this type. However, you'll get a runtime error when you pass an argument of the Alpha type because there's no method that can handle this object (a generic method has the constraint where T : IItem and Alpha class doesn't implement this interface). But that's the whole point. The compiler doesn't have information that this call is valid. You as a programmer know this, and you should make sure that this code runs without errors.

Return type gotcha

When you're calling a non-void method with a parameter of dynamic type, its return type will probably be dynamic too. So if you'd change previous example to this code:

var result = ProcessItem((dynamic)testObjects[i], "test" + i, i);

then the type of the result object would be dynamic. This is because the compiler don't always know which method will be called. If you know the return type of the function call then you should implicitly convert it to the required type so the rest of the code is statically typed:

string result = ProcessItem((dynamic)testObjects[i], "test" + i, i);

You'll get a runtime error if the type doesn't match.

Actually, if you try to get the result value in the previous example then you'll get a runtime error in the second loop iteration. This is because you tried to save the return value of a void function.

For new Qt users this is a little more confusing than it seems if you are using QT Designer and .ui files.

Initially I tried to use ui->setWindowTitle, but that doesn't exist. ui is not a QDialog or a QMainWindow.

The owner of the ui is the QDialog or QMainWindow, the .ui just describes how to lay it out. In that case, you would use:

this->setWindowTitle("New Title");

I hope this helps someone else.

If you want to set image as background for whole page, use this:

}

There are really great answers above to the asked question. There might be no need for another answer but still I want to give my personal opinion on the topic in the simplest words possible.

Here are some points about containers & images that will help us for a conclusion:

• A docker image can be:
  1. created-from-a-given-container
  2. deleted
  3. used-to-create-any-number-of-containers
• A docker container can be:
  1. created-from-an-image
  2. started
  3. stopped
  4. restarted
  5. deleted
  6. used-to-create-any-number-of-images
• A docker run command does this:
  1. Downloads an image or uses a cached image
  2. Creates a new container out of it
  3. Starts the container
• When a Dockerfile is used to create an image:
  1. It is already well known that the image will eventually be used to run a docker container.
  2. After issuing docker build command, docker behind-the-scenes creates a running container with a base-file-system and follows steps inside the Dockerfile to configure that container as per the developers need.
  3. After the container is configured with specs of the Dockerfile, it will be committed as an image.
  4. The image gets ready to rock & roll!

Conclusion:

As we can see, a docker container is independent of a docker image.

A container can be restarted provided the unique ID of that container [use docker ps --all to get the id].

Any operation like making a new directory, creating files, installing tools, etc. can be done inside the container when it is running. Once the container is stopped, it persists all the changes. Container stopping and restarting is like rebooting a computer system.

An already created container is always available for a restart but when we issue docker run command, a new container is created out of an image and hence it is like a new computer system. The changes made inside the old container - as we can understand now - are not available in this new container.

A final note:

I guess it's now obvious why the data seems to be lost yet it is always there.. but in a different [old] container. So, take a good note of the difference in docker start & docker run command & never get confused in them.

There is a pretty nice infinite scroll plugin here

I've never programmed one myself, but I would imagine this is how it works.

1. An event is bound to the the window scrolling

   $(window).scroll(myInfinteScrollFunction);
   

2. The called function checks if scroll top is greater than the window size

   function myInfiniteScrollFunction() {  
       if($(window).scrollTop() == $(window).height())  
       makeAjaxRequest();  
   }
   

3. An AJAX request is made, specifying which result # to start at, how many to grab, and any other parameters necessary for the data pull.

   $.ajax({
       type: "POST",
       url:  "myAjaxFile.php",
       data: {"resultNum": 30, "numPerPage": 50, "query": "interesting%20icons" },
       success: myInfiniteLoadFunction(msg)
   });
   

4. The ajax returns some (most-likely JSON formatted) content, and passes them into the loadnig function.

Hope that makes sense.

As mentioned above:

The GOPATH environment variable specifies the location of your workspace.

For Windows, this worked for me (in Ms-dos window):

set GOPATH=D:\my_folder_for_go_code\

This creates a GOPATH variable that Ms-dos recognizes when used as follows:

cd %GOPATH%

A regular pipe can only connect two related processes. It is created by a process and will vanish when the last process closes it.

A named pipe, also called a FIFO for its behavior, can be used to connect two unrelated processes and exists independently of the processes; meaning it can exist even if no one is using it. A FIFO is created using the mkfifo() library function.

Example

writer.c

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

int main()
{
    int fd;
    char * myfifo = "/tmp/myfifo";

    /* create the FIFO (named pipe) */
    mkfifo(myfifo, 0666);

    /* write "Hi" to the FIFO */
    fd = open(myfifo, O_WRONLY);
    write(fd, "Hi", sizeof("Hi"));
    close(fd);

    /* remove the FIFO */
    unlink(myfifo);

    return 0;
}

reader.c

#include <fcntl.h>
#include <stdio.h>
#include <sys/stat.h>
#include <unistd.h>

#define MAX_BUF 1024

int main()
{
    int fd;
    char * myfifo = "/tmp/myfifo";
    char buf[MAX_BUF];

    /* open, read, and display the message from the FIFO */
    fd = open(myfifo, O_RDONLY);
    read(fd, buf, MAX_BUF);
    printf("Received: %s\n", buf);
    close(fd);

    return 0;
}

_{Note: Error checking was omitted from the above code for simplicity.}

MySQL now has support for spatial data types since this question was asked. So the the current accepted answer is not wrong, but if you're looking for additional functionality like finding all points within a given polygon then use POINT data type.

Checkout the Mysql Docs on Geospatial data types and the spatial analysis functions

Change this:

if(isset($_POST['submit'])){

    if(!(isset($_POST['userName']))){
    $username = 'Anonymous';
    }      
    else $username = $_POST['userName'];
}

To this:

if(!empty($_POST['userName'])){
     $username = $_POST['userName'];
}

if(empty($_POST['userName'])){
     $username = 'Anonymous';
}

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

External fragmentation
Total memory space is enough to satisfy a request or to reside a process in it, but it is not contiguous so it can not be used.

Internal fragmentation
Memory block assigned to process is bigger. Some portion of memory is left unused as it can not be used by another process.

As simple String extension should suffice:

extension String {

    var parseJSONString: AnyObject? {

        let data = self.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)

        if let jsonData = data {
            // Will return an object or nil if JSON decoding fails
            return NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers, error: nil)
        } else {
            // Lossless conversion of the string was not possible
            return nil
        }
    }
}

Then:

var jsonString = "[\n" +
    "{\n" +
    "\"id\":72,\n" +
    "\"name\":\"Batata Cremosa\",\n" +            
    "},\n" +
    "{\n" +
    "\"id\":183,\n" +
    "\"name\":\"Caldeirada de Peixes\",\n" +            
    "},\n" +
    "{\n" +
    "\"id\":76,\n" +
    "\"name\":\"Batata com Cebola e Ervas\",\n" +            
    "},\n" +
    "{\n" +
    "\"id\":56,\n" +
    "\"name\":\"Arroz de forma\",\n" +            
"}]"

let json: AnyObject? = jsonString.parseJSONString
println("Parsed JSON: \(json!)")
println("json[3]: \(json![3])")

/* Output:

Parsed JSON: (
    {
    id = 72;
    name = "Batata Cremosa";
    },
    {
    id = 183;
    name = "Caldeirada de Peixes";
    },
    {
    id = 76;
    name = "Batata com Cebola e Ervas";
    },
    {
    id = 56;
    name = "Arroz de forma";
    }
)

json[3]: {
    id = 56;
    name = "Arroz de forma";
}
*/

PermGen stands for Permanent Generation.

Here is a brief blurb on DDJ

Implement onFocusChange of setOnFocusChangeListener and there's a boolean parameter for hasFocus. When this is false, you've lost focus to another control.

 EditText txtEdit = (EditText) findViewById(R.id.edittxt);

 txtEdit.setOnFocusChangeListener(new OnFocusChangeListener() {          
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus) {
               // code to execute when EditText loses focus
            }
        }
    });

This is the perfect kind of field to define as CHAR 36, by the way, not VARCHAR 36, since each value will have the exact same length. And you'll use less storage space, since you don't need to store the data length for each value, just the value.

I would just like to add that if the String is originally encoded using the wrong encoding it might be impossible to change it to another encoding without errors. The question does not state that the conversion here is made from wrong encoding to correct encoding but I personally stumbled to this question just because of this situation so just a heads up for others as well.

This answer in other question gives an explanation why the conversion does not always yield correct results https://stackoverflow.com/a/2623793/4702806

1. Use this: URLEncoder.encode(query, StandardCharsets.UTF_8.displayName()); or this:URLEncoder.encode(query, "UTF-8");

2. You can use the follwing code.

   String encodedUrl1 = UriUtils.encodeQuery(query, "UTF-8");//not change 
   String encodedUrl2 = URLEncoder.encode(query, "UTF-8");//changed
   String encodedUrl3 = URLEncoder.encode(query, StandardCharsets.UTF_8.displayName());//changed
   
   System.out.println("url1 " + encodedUrl1 + "\n" + "url2=" + encodedUrl2 + "\n" + "url3=" + encodedUrl3);
   

In PHP 5.4 you can use JSON_PRETTY_PRINT if you are using the function json_encode.

json_encode(array('one', 'two', 'three'), JSON_PRETTY_PRINT);

Place all files need to copied in a separate folder, for ease place them in c drive.

Open Command Prompt - windows>type cmd>select command prompt.

You can see the default directory pointing - Ex : C:[Folder_Name]>. Change the directory to point to the folder which you have placed files to be copied, using ' cd [Folder_Name] ' command.

After pointing to directory - type 'dir' which shows all the files present in folder, just to make sure everything at place.

Now type : 'copy *.txt [newfile_name].txt' and press enter.

Done!

All the text in individual files will be copied to [newfile_name].txt

Try this instead of your code:

var type=$("#the-span").attr("data-type");
alert(type);

Here's one way:

// Utility function to extract arg name-value pairs
function getArgs(args) {
    var argsObj = {};

    var argList = /\(([^)]*)/.exec(args.callee)[1];
    var argCnt = 0;
    var tokens;
    var argRe = /\s*([^,]+)/g;

    while (tokens = argRe.exec(argList)) {
        argsObj[tokens[1]] = args[argCnt++];
    }

    return argsObj;
}

// Test subject
function add(number1, number2) {
    var args = getArgs(arguments);
    console.log(args); // ({ number1: 3, number2: 4 })
}

// Invoke test subject
add(3, 4);

Note: This only works on browsers that support arguments.callee.

If you're still getting a env: ruby_executable_hooks: No such file or directory when calling some Ruby package, that means RVM left a little gift for you in your $PATH.

Run the following to find the offending scripts:

grep '#!/usr/bin/env ruby_executable_hooks' /usr/local/bin/*

Then rm all the matches. You'll have to reinstall all of those libraries with an RVM-free gem, of course.

If you want to allow 1 and 1.2:

(?<=^| )\d+(\.\d+)?(?=$| )

If you want to allow 1, 1.2 and .1:

(?<=^| )\d+(\.\d+)?(?=$| )|(?<=^| )\.\d+(?=$| )

If you want to only allow 1.2 (only floats):

(?<=^| )\d+\.\d+(?=$| )

\d allows digits (while \D allows anything but digits).

(?<=^| ) checks that the number is preceded by either a space or the beginning of the string. (?=$| ) makes sure the string is followed by a space or the end of the string. This makes sure the number isn't part of another number or in the middle of words or anything.

Edit: added more options, improved the regexes by adding lookahead- and behinds for making sure the numbers are standalone (i.e. aren't in the middle of words or other numbers.

On Oracle Linux 7.x running PHP version 7.3.x you need to run sudo yum install php-mysqlnd in order to install the missing MySQL extension for PHP.

Remember to restart PHP and or your server for the changes to take effect.

I also faced the same problem while working with eclips Neon. It got fixed after editing the .ini file with following content:

>    -Dhttp.proxyPort=8080

>    -Dhttp.proxyHost=myproxy

>    -Dhttp.proxyUser=mydomain\myusername

>    -Dhttp.proxyPassword=mypassword

>    -Dhttp.nonProxyHosts=localhost|127.0.0.1

>    -Djava.net.preferIPv4Stack=true

Note: Sometime it may also caused due to the issue with your Network configuration and device. So conform first that your windows firewall is allowing to connect your eclips to the outer world (internet). (Turn off the windows firewall for the instance of time that your computer take to install the file).

If you don't have access to getDefaultSharedPreferenes(), you can use getSharedPreferences(name, mode) instead, you just have to pass in the right name.

Android creates this name (possibly based on the package name of your project?). You can get it by putting the following code in a SettingsActivity onCreate(), and seeing what preferencesName is.

String preferencesName = this.getPreferenceManager().getSharedPreferencesName();

The string should be something like com.example.projectname_preferences. Hard code that somewhere in your project, and pass it in to getSharedPreferences() and you should be good to go.

If you want to UPDATE a tag, let's say it 1.0.0

1. git checkout 1.0.0
2. make your changes
3. git ci -am 'modify some content'
4. git tag -f 1.0.0
5. delete remote tag on github: git push origin --delete 1.0.0
6. git push origin 1.0.0

DONE

It's always dangerous to have NULL in the IN list - it often behaves as expected for the IN but not for the NOT IN:

IF 1 NOT IN (1, 2, 3, NULL) PRINT '1 NOT IN (1, 2, 3, NULL)'
IF 1 NOT IN (2, 3, NULL) PRINT '1 NOT IN (2, 3, NULL)'
IF 1 NOT IN (2, 3) PRINT '1 NOT IN (2, 3)' -- Prints
IF 1 IN (1, 2, 3, NULL) PRINT '1 IN (1, 2, 3, NULL)' -- Prints
IF 1 IN (2, 3, NULL) PRINT '1 IN (2, 3, NULL)'
IF 1 IN (2, 3) PRINT '1 IN (2, 3)'

That's because arc4random_uniform() is defined as follows:

func arc4random_uniform(_: UInt32) -> UInt32

It takes a UInt32 as input, and spits out a UInt32. You're attempting to pass it a range of values. arc4random_uniform gives you a random number in between 0 and and the number you pass it (exclusively), so if for example, you wanted to find a random number between -50 and 50, as in [-50, 50] you could use arc4random_uniform(101) - 50

If you are getting this message from a Maven built war change the scope of the JDBC driver to provided, and put a copy of it in the lib directory. Like this:

If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes. You set request header Content-Type: multipart/form-data; boundary=HereGoes. Then this should be a valid request body:

--HereGoes
Content-Disposition: form-data; name="myJsonString"
Content-Type: application/json

{"foo": "bar"}
--HereGoes
Content-Disposition: form-data; name="photo"
Content-Type: image/jpeg
Content-Transfer-Encoding: base64

<...JPEG content in base64...>
--HereGoes--

Minix is a lot smaller, and designed for learning purposes, and the book to go with it is a good one too.

Update: I guess Minix 3 is a bit of a different goal, but Minix 2 (and of course the first version) were for teaching purposes.

I had the same issue... I was using maven building tool with JUnit dependency scope as 'test' and my @Test method was in main module.

To resolve, I've: 1. Commented the scope tag of JUnit dependency in the pom.xml 2. Rebuilt the package 3. Made sure the Test class has only one constructor

The issue can be two-folded: 1. The JUnit dependency is limited to test scope and the @Test method is in main scope 2. The test class has more than one constructor

The short answer is: don't use malloc for C++ without a really good reason for doing so. malloc has a number of deficiencies when used with C++, which new was defined to overcome.

Deficiencies fixed by new for C++ code

1. malloc is not typesafe in any meaningful way. In C++ you are required to cast the return from void*. This potentially introduces a lot of problems:

   #include <stdlib.h>
   
   struct foo {
     double d[5];
   }; 
   
   int main() {
     foo *f1 = malloc(1); // error, no cast
     foo *f2 = static_cast<foo*>(malloc(sizeof(foo)));
     foo *f3 = static_cast<foo*>(malloc(1)); // No error, bad
   }
   

2. It's worse than that though. If the type in question is POD (plain old data) then you can semi-sensibly use malloc to allocate memory for it, as f2 does in the first example.

   It's not so obvious though if a type is POD. The fact that it's possible for a given type to change from POD to non-POD with no resulting compiler error and potentially very hard to debug problems is a significant factor. For example if someone (possibly another programmer, during maintenance, much later on were to make a change that caused foo to no longer be POD then no obvious error would appear at compile time as you'd hope, e.g.:

   struct foo {
     double d[5];
     virtual ~foo() { }
   };
   

   would make the malloc of f2 also become bad, without any obvious diagnostics. The example here is trivial, but it's possible to accidentally introduce non-PODness much further away (e.g. in a base class, by adding a non-POD member). If you have C++11/boost you can use is_pod to check that this assumption is correct and produce an error if it's not:

   #include <type_traits>
   #include <stdlib.h>
   
   foo *safe_foo_malloc() {
     static_assert(std::is_pod<foo>::value, "foo must be POD");
     return static_cast<foo*>(malloc(sizeof(foo)));
   }
   

   Although boost is unable to determine if a type is POD without C++11 or some other compiler extensions.

3. malloc returns NULL if allocation fails. new will throw std::bad_alloc. The behaviour of later using a NULL pointer is undefined. An exception has clean semantics when it is thrown and it is thrown from the source of the error. Wrapping malloc with an appropriate test at every call seems tedious and error prone. (You only have to forget once to undo all that good work). An exception can be allowed to propagate to a level where a caller is able to sensibly process it, where as NULL is much harder to pass back meaningfully. We could extend our safe_foo_malloc function to throw an exception or exit the program or call some handler:

   #include <type_traits>
   #include <stdlib.h>
   
   void my_malloc_failed_handler();
   
   foo *safe_foo_malloc() {
     static_assert(std::is_pod<foo>::value, "foo must be POD");
     foo *mem = static_cast<foo*>(malloc(sizeof(foo)));
     if (!mem) {
        my_malloc_failed_handler();
        // or throw ...
     }
     return mem;
   }
   

4. Fundamentally malloc is a C feature and new is a C++ feature. As a result malloc does not play nicely with constructors, it only looks at allocating a chunk of bytes. We could extend our safe_foo_malloc further to use placement new:

   #include <stdlib.h>
   #include <new>
   
   void my_malloc_failed_handler();
   
   foo *safe_foo_malloc() {
     void *mem = malloc(sizeof(foo));
     if (!mem) {
        my_malloc_failed_handler();
        // or throw ...
     }
     return new (mem)foo();
   }
   

5. Our safe_foo_malloc function isn't very generic - ideally we'd want something that can handle any type, not just foo. We can achieve this with templates and variadic templates for non-default constructors:

   #include <functional>
   #include <new>
   #include <stdlib.h>
   
   void my_malloc_failed_handler();
   
   template <typename T>
   struct alloc {
     template <typename ...Args>
     static T *safe_malloc(Args&&... args) {
       void *mem = malloc(sizeof(T));
       if (!mem) {
          my_malloc_failed_handler();
          // or throw ...
       }
       return new (mem)T(std::forward(args)...);
     }
   };
   

   Now though in fixing all the issues we identified so far we've practically reinvented the default new operator. If you're going to use malloc and placement new then you might as well just use new to begin with!

Use Tensorflow eager execution mode which is latest.

my_int_variable = tf.get_variable("my_int_variable", [1, 2, 3])
print(my_int_variable)

There is part of the spec that sure sounds like this... right in the "flex layout algorithm" and "main sizing" sections:

Otherwise, starting from the first uncollected item, collect consecutive items one by one until the first time that the next collected item would not fit into the flex container’s inner main size, or until a forced break is encountered. If the very first uncollected item wouldn’t fit, collect just it into the line. A break is forced wherever the CSS2.1 page-break-before/page-break-after [CSS21] or the CSS3 break-before/break-after [CSS3-BREAK] properties specify a fragmentation break.

From http://www.w3.org/TR/css-flexbox-1/#main-sizing

It sure sounds like (aside from the fact that page-breaks ought to be for printing), when laying out a potentially multi-line flex layout (which I take from another portion of the spec is one without flex-wrap: nowrap) a page-break-after: always or break-after: always should cause a break, or wrap to the next line.

.flex-container {
  display: flex;
  flex-flow: row wrap;
}

.child {
  flex-grow: 1;
}

.child.break-here {
  page-break-after: always;
  break-after: always;
}

However, I have tried this and it hasn't been implemented that way in...

• Safari (up to 7)
• Chrome (up to 43 dev)
• Opera (up to 28 dev & 12.16)
• IE (up to 11)

It does work the way it sounds (to me, at least) like in:

• Firefox (28+)

Sample at http://codepen.io/morewry/pen/JoVmVj.

I didn't find any other requests in the bug tracker, so I reported it at https://code.google.com/p/chromium/issues/detail?id=473481.

But the topic took to the mailing list and, regardless of how it sounds, that's not what apparently they meant to imply, except I guess for pagination. So there's no way to wrap before or after a particular box in flex layout without nesting successive flex layouts inside flex children or fiddling with specific widths (e.g. flex-basis: 100%).

This is deeply annoying, of course, since working with the Firefox implementation confirms my suspicion that the functionality is incredibly useful. Aside from the improved vertical alignment, the lack obviates a good deal of the utility of flex layout in numerous scenarios. Having to add additional wrapping tags with nested flex layouts to control the point at which a row wraps increases the complexity of both the HTML and CSS and, sadly, frequently renders order useless. Similarly, forcing the width of an item to 100% reduces the "responsive" potential of the flex layout or requires a lot of highly specific queries or count selectors (e.g. the techniques that may accomplish the general result you need that are mentioned in the other answers).

At least floats had clear. Something may get added at some point or another for this, one hopes.

you could deserialize your json string into a dictionary and then add new properties then serialize it.

 var jsonString = @"{}";

        var jsonDoc = JsonSerializer.Deserialize<Dictionary<string, object>>(jsonString);

        jsonDoc.Add("Name", "Khurshid Ali");

        Console.WriteLine(JsonSerializer.Serialize(jsonDoc));

What ever attribute is added to the button/anchor/link to disable it, bootstrap is just adding style to it and user will still be able to click it while there is still onclick event. So my simple solution is to check if it is disabled and remove/add onclick event:

if (!('#button').hasAttr('disabled'))
 $('#button').attr('onclick', 'someFunction();');
else
 $('#button').removeattr('onclick');

I think a lot of people are wanting to be able to check to see if their variable is not empty as well as if it exists. I think that checking for existence and emptiness is a good idea in a lot of cases, and makes your template more robust and less prone to silly errors. In other words, if you check to make sure your variable is not null AND not empty before using it, then your template becomes more flexible, because you can throw either a null variable or an empty string into it, and it will work the same in either case.

<#if p?? && p?has_content>1</#if>

Let's say you want to make sure that p is more than just whitespace. Then you could trim it before checking to see if it has_content.

<#if p?? && p?trim?has_content>1</#if>

UPDATE

Please ignore my suggestion -- has_content is all that is needed, as it does a null check along with the empty check. Doing p?? && p?has_content is equivalent to p?has_content, so you may as well just use has_content.

These are exactly the same. android:onClick was added in API level 4 to make it easier, more Javascript-web-like, and drive everything from the XML. What it does internally is add an OnClickListener on the Button, which calls your DoIt method.

Here is what using a android:onClick="DoIt" does internally:

Button button= (Button) findViewById(R.id.buttonId);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        DoIt(v);
    }
});

The only thing you trade off by using android:onClick, as usual with XML configuration, is that it becomes a bit more difficult to add dynamic content (programatically, you could decide to add one listener or another depending on your variables). But this is easily defeated by adding your test within the DoIt method.

The first method is the proper approach and will do what you need. However, with the inner joins, you will only select rows from Table1 if both phone numbers exist in Table2. You may want to do a LEFT JOIN so that all rows from Table1 are selected. If the phone numbers don't match, then the SomeOtherFields would be null. If you want to make sure you have at least one matching phone number you could then do WHERE t2.PhoneNumber IS NOT NULL OR t3.PhoneNumber IS NOT NULL

The second method could have a problem: what happens if Table2 has both PhoneNumber1 and PhoneNumber2? Which row will be selected? Depending on your data, foreign keys, etc. this may or may not be a problem.

Other answers already on Stackoverflow:

• How do I install modules locally without root access...
• How can I use a new Perl module without install permissions?

From perlfaq8:

When you build modules, tell Perl where to install the modules.

For Makefile.PL-based distributions, use the INSTALL_BASE option when generating Makefiles:

perl Makefile.PL INSTALL_BASE=/mydir/perl

You can set this in your CPAN.pm configuration so modules automatically install in your private library directory when you use the CPAN.pm shell:

% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit

For Build.PL-based distributions, use the --install_base option:

perl Build.PL --install_base /mydir/perl

You can configure CPAN.pm to automatically use this option too:

% cpan
cpan> o conf mbuildpl_arg '--install_base /mydir/perl'
cpan> o conf commit

As per PEP-20 by Tim Peters, "Explicit is better than implicit" and "Readability counts". If all you need from the os module is under os.path, import os.path would be more explicit and let others know what you really care about.

Likewise, PEP-20 also says "Simple is better than complex", so if you also need stuff that resides under the more-general os umbrella, import os would be preferred.

The estimated execution plan is generated by the Optimizer without running the SQL query.

In order to get the estimated execution plan, you need to enable the SHOWPLAN_ALL setting prior to executing the query.

SET SHOWPLAN_ALL ON

Now, when executing the following SQL query:

SELECT p.id
FROM post p
WHERE EXISTS (
  SELECT 1
  FROM post_comment pc
  WHERE
    pc.post_id = p.id AND
    pc.review = 'Bingo'
)
ORDER BY p.title
OFFSET 20 ROWS
FETCH NEXT 10 ROWS ONLY

SQL Server will generate the following estimated execution plan:

| NodeId | Parent | LogicalOp            | EstimateRows | EstimateIO  | EstimateCPU | AvgRowSize | TotalSubtreeCost | EstimateExecutions |
|--------|--------|----------------------|--------------|-------------|-------------|------------|------------------|--------------------|
| 1      | 0      | NULL                 | 10           | NULL        | NULL        | NULL       | 0.03374284       | NULL               |
| 2      | 1      | Top                  | 10           | 0           | 3.00E-06    | 15         | 0.03374284       | 1                  |
| 4      | 2      | Distinct Sort        | 30           | 0.01126126  | 0.000504114 | 146        | 0.03373984       | 1                  |
| 5      | 4      | Inner Join           | 46.698       | 0           | 0.00017974  | 146        | 0.02197446       | 1                  |
| 6      | 5      | Clustered Index Scan | 43           | 0.004606482 | 0.0007543   | 31         | 0.005360782      | 1                  |
| 7      | 5      | Clustered Index Seek | 1            | 0.003125    | 0.0001581   | 146        | 0.0161733        | 43                 |

After running the query we are interested in getting the estimated execution plan, you need to disable the SHOWPLAN_ALL as, otherwise, the current database session will only generate estimated execution plan instead of executing the provided SQL queries.

SET SHOWPLAN_ALL OFF

SQL Server Management Studio estimated plan

In the SQL Server Management Studio application, you can easily get the estimated execution plan for any SQL query by hitting the CTRL+L key shortcut.

Actual execution plan

The actual SQL execution plan is generated by the Optimizer when running the SQL query. If the database table statistics are accurate, the actual plan should not differ significantly from the estimated one.

To get the actual execution plan on SQL Server, you need to enable the STATISTICS IO, TIME, PROFILE settings, as illustrated by the following SQL command:

SET STATISTICS IO, TIME, PROFILE ON

Now, when running the previous query, SQL Server is going to generate the following execution plan:

| Rows | Executes | NodeId | Parent | LogicalOp            | EstimateRows | EstimateIO  | EstimateCPU | AvgRowSize | TotalSubtreeCost |
|------|----------|--------|--------|----------------------|--------------|-------------|-------------|------------|------------------|
| 10   | 1        | 1      | 0      | NULL                 | 10           | NULL        | NULL        | NULL       | 0.03338978       |
| 10   | 1        | 2      | 1      | Top                  | 1.00E+01     | 0           | 3.00E-06    | 15         | 0.03338978       |
| 30   | 1        | 4      | 2      | Distinct Sort        | 30           | 0.01126126  | 0.000478783 | 146        | 0.03338679       |
| 41   | 1        | 5      | 4      | Inner Join           | 44.362       | 0           | 0.00017138  | 146        | 0.02164674       |

Google Apps Script will not open automatically web pages, but it could be used to display a message with links, buttons that the user could click on them to open the desired web pages or even to use the Window object and methods like addEventListener() to open URLs.

It's worth to note that UiApp is now deprecated. From Class UiApp - Google Apps Script - Google Developers

Deprecated. The UI service was deprecated on December 11, 2014. To create user interfaces, use the HTML service instead.

The example in the HTML Service linked page is pretty simple,

Code.gs

// Use this code for Google Docs, Forms, or new Sheets.
function onOpen() {
  SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
      .createMenu('Dialog')
      .addItem('Open', 'openDialog')
      .addToUi();
}

function openDialog() {
  var html = HtmlService.createHtmlOutputFromFile('index')
      .setSandboxMode(HtmlService.SandboxMode.IFRAME);
  SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
      .showModalDialog(html, 'Dialog title');
}

How about this?

SUM(IF(PaymentType = "credit card", totalamount, 0)) AS CreditCardTotal

By using pandas we can read excel easily.

import pandas as pd 
from pandas import ExcelWriter
from pandas import ExcelFile 

DataF=pd.read_excel("Test.xlsx",sheet_name='Sheet1')

print("Column headings:")
print(DataF.columns)

Test at :https://repl.it Reference: https://pythonspot.com/read-excel-with-pandas/

A little bigger perspective of the solution:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.yourlayout, container, false);
        View tv = v.findViewById(R.id.et1);
        ((TextView) tv).addTextChangedListener(new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                 SpannableString contentText = new SpannableString(((TextView) tv).getText());
                 String contents = Html.toHtml(contentText).toString();
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                // TODO Auto-generated method stub
            }

            @Override
            public void afterTextChanged(Editable s) {

                // TODO Auto-generated method stub
            }
        });
        return v;
    }

This works for me, doing it my first time.

You should probably re-write the script to return a value rather than output it. Instead of:

a=$( script.sh ) # Now a is a string, either "success" or "Failed"
case "$a" in
   success) echo script succeeded;;
   Failed) echo script failed;;
esac

you would be able to do:

if script.sh > /dev/null; then
    echo script succeeded
else
    echo script failed
fi

It is much simpler for other programs to work with you script if they do not have to parse the output. This is a simple change to make. Just exit 0 instead of printing success, and exit 1 instead of printing Failed. Of course, you can also print those values as well as exiting with a reasonable return value, so that wrapper scripts have flexibility in how they work with the script.
