$image = imagecreatefromjpeg($_GET['src']);
$filename = 'images/cropped_whatever.jpg'
Must be replaced with:
$image = imagecreatefromjpeg($_GET['src']);
Then it will work!
There is a conflict between (Safari) and (Opera) and (Chrome) !!!
The above codes couldn't work properly
This is my code, and it works very well without any conflict:
function ExactBrowserName()
{

if (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")) {
// OPERA
$ExactBrowserNameBR="Opera";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "chrome/")) {
// CHROME
$ExactBrowserNameBR="Chrome";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "msie")) {
// INTERNET EXPLORER
$ExactBrowserNameBR="Internet Explorer";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "firefox/")) {
// FIREFOX
$ExactBrowserNameBR="Firefox";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")==false and strpos(strtolower($ExactBrowserNameUA), "chrome/")==false) {
// SAFARI
$ExactBrowserNameBR="Safari";
} else {

This is expected behavior for an uncaught exception with display_errors off.
Your options here are to turn on display_errors via php or in the ini file or catch and output the exception.
ini_set("display_errors", 1);
or
try{
// code that may throw an exception
} catch(Exception $e){
echo $e->getMessage();
}
If you are throwing exceptions, the intention is that somewhere further down the line something will catch and deal with it. If not it is a server error (500).
Another option for you would be to use set_exception_handler to set a default error handler for your script.
function default_exception_handler(Exception $e){
// show something to the user letting them know we fell down
echo "<h2>Something Bad Happened</h2>";
echo "<p>We fill find the person responsible and have them shot</p>";
// do some logging for the exception and call the kill_programmer function.
}
set_exception_handler("default_exception_handler");
The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo
ls
show the right files?git init
? (git-init documentation)Either of those would cause your error.
In answer to your first question, there's no parameter substitution because you've put the delimiter in quotes - the bash manual says:
The format of here-documents is:
<<[-]word here-document delimiter
No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. [...]
If you change your first example to use <<EOF
instead of << "EOF"
you'll find that it works.
In your second example, the shell invokes sudo
only with the parameter cat
, and the redirection applies to the output of sudo cat
as the original user. It'll work if you try:
sudo sh -c "cat > /path/to/outfile" <<EOT

It depends on what concrete List class you are using. The abstract class AbstractCollection has a method called containsAll(Collection) that takes another collection ( a List is a collection) and:
Returns true if this collection contains all of the elements in the specified collection.
So if an ArrayList is being passed in you can call this method to see if they are exactly the same.
List foo = new ArrayList();
List bar = new ArrayList();
String str = "foobar";
foo.add(str);
bar.add(str);
foo.containsAll(bar);
The reason for containsAll() is because it iterates through the first list looking for the match in the second list. So if they are out of order equals() will not pick it up.
EDIT: I just want to make a comment here about the amortized running time of performing the various options being offered. Is running time important? Sure. Is it the only thing you should consider? No.
The cost of copying EVERY single element from your lists into other lists takes time, and it also takes up a good chunk of memory (effectively doubling the memory you are using).
So if memory in your JVM isn't a concern (which it should generally be) then you still need to consider the time it takes to copy every element from two lists into two TreeSets. Remember it is sorting every element as it enters them.
My final advice? You need to consider your data set and how many elements you have in your data set, and also how large each object in your data set is before you can make a good decision here. Play around with them, create one each way and see which one runs faster. It's a good exercise.
If you want to replace characters in string, you should create mutable strings. These are essentially character arrays. You could create a factory:
function MutableString(str) {
var result = str.split("");
result.toString = function() {
return this.join("");
}
return result;
}
Then you can access the characters and the whole array converts to string when used as string:
var x = MutableString("Hello");
x[0] = "B"; // yes, we can alter the character
x.push("!"); // good performance: no new string is created
var y = "Hi, "+x; // converted to string: "Hi, Bello!"
A better way to normalize your image is to take each value and divide by the largest value experienced by the data type. This ensures that images that have a small dynamic range in your image remain small and they're not inadvertently normalized so that they become gray. For example, if your image had a dynamic range of [0-2]
, the code right now would scale that to have intensities of [0, 128, 255]
. You want these to remain small after converting to np.uint8
.
Therefore, divide every value by the largest value possible by the image type, not the actual image itself. You would then scale this by 255 to produced the normalized result. Use numpy.iinfo
and provide it the type (dtype
) of the image and you will obtain a structure of information for that type. You would then access the max
field from this structure to determine the maximum value.
So with the above, do the following modifications to your code:
import numpy as np
import cv2
[...]
info = np.iinfo(data.dtype) # Get the information of the incoming image type
data = data.astype(np.float64) / info.max # normalize the data to 0 - 1
data = 255 * data # Now scale by 255
img = data.astype(np.uint8)
cv2.imshow("Window", img)
Note that I've additionally converted the image into np.float64
in case the incoming data type is not so and to maintain floating-point precision when doing the division.
The same origin policy is applicable only for browser side programming languages. So if you try to post to a different server than the origin server using JavaScript, then the same origin policy comes into play but if you post directly from the form i.e. the action points to a different server like:
<form action="http://someotherserver.com">
and there is no javascript involved in posting the form, then the same origin policy is not applicable.

An even more elegant solution is to limit the text by the number of words (and not by number of characters). This prevents ugly tear throughs (e.g. 'Stackov...').
Here's an example where I shorten only text blocks longer than 10 words:
{% set text = myentity.text |split(' ') %}
{% if text|length > 10 %}
{% for t in text|slice(0, 10) %}
{{ t }}
{% endfor %}
...
{% else %}
{{ text|join(' ') }}
{% endif %}

Yes, we can assign variables from child controller to the variables in parent controller. This is one possible way:
Overview: The main aim of the code, below, is to assign child controller's $scope.variable to parent controller's $scope.assign
Explanation: There are two controllers. In the html, notice that the parent controller encloses the child controller. That means the parent controller will be executed before child controller. So, first setValue() will be defined and then the control will go to the child controller. $scope.variable will be assigned as "child". Then this child scope will be passed as an argument to the function of parent controller, where $scope.assign will get the value as "child"
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script type="text/javascript">
var app = angular.module('myApp',[]);
app.controller('child',function($scope){
$scope.variable = "child";
$scope.$parent.setValue($scope);
});
app.controller('parent',function($scope){
$scope.setValue = function(childscope) {
$scope.assign = childscope.variable;
}
});
</script>
<body ng-app="myApp">
<div ng-controller="parent">
<p>this is parent: {{assign}}</p>
<div ng-controller="child">
<p>this is {{variable}}</p>
</div>
</div>
</body>
</html>
You can use python -m http.server
. By default the local server will run on port 8000. If you would like to change this, simply add the port number python -m http.server 1234
If you are using python 2 (instead of 3), the equivalent command is python -m SimpleHTTPServer
Use Application.StartupPath
for the best result imo.
Well, you need to incorporate exec-maven-plugin
, this plug-in performs the same thing that you do on command prompt when you type in java -cp .;jarpaths TestMain
. You can pass argument and define which phase (test
, package
, integration
, verify
, or deploy
), you want this plug-in to call your main class.
You need to add this plug-in under <build>
tag and specify parameters. For example
<project>
...
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1.1</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>my.company.name.packageName.TestMain</mainClass>
<arguments>
<argument>myArg1</argument>
<argument>myArg2</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
...
</project>
Now, if you right-click on on the project folder and do Run As > Maven Test
, or Run As > Maven Package
or Run As > Maven Install
, the test phase
will execute and so your Main class.
CASE
in MySQL is both a statement and an expression, where each usage is slightly different.
As a statement, CASE
works much like a switch statement and is useful in stored procedures, as shown in this example from the documentation (linked above):
DELIMITER |
CREATE PROCEDURE p()
BEGIN
DECLARE v INT DEFAULT 1;
CASE v
WHEN 2 THEN SELECT v;
WHEN 3 THEN SELECT 0;
ELSE
BEGIN -- Do other stuff
END;
END CASE;
END;
|
However, as an expression it can be used in clauses:
SELECT *
FROM employees
ORDER BY
CASE title
WHEN "President" THEN 1
WHEN "Manager" THEN 2
ELSE 3
END, surname
Additionally, both as a statement and as an expression, the first argument can be omitted and each WHEN
must take a condition.
SELECT *
FROM employees
ORDER BY
CASE
WHEN title = "President" THEN 1
WHEN title = "Manager" THEN 2
ELSE 3
END, surname
I provided this answer because the other answer fails to mention that CASE
can function both as a statement and as an expression. The major difference between them is that the statement form ends with END CASE
and the expression form ends with just END
.
On top of @kp's answer:
I'm dealing with this and in my case, I have to show a child element and correct the height of the parent object accordingly (auto-sizing is not working in a bootstrap header for some reason I don't have time to debug).
But instead of using javascript to modify the parent, I think I'll dynamically add a CSS class to the parent and CSS-selectively show the children accordingly. This will maintain the decisions in the logic and not based on a CSS state.
tl;dr; apply the a
and b
styles to the parent <div>
, not the child (of course, not everyone will be able to do this. i.e. Angular components making decisions of their own).
<style>
.parent { height: 50px; }
.parent div { display: none; }
.with-children { height: 100px; }
.with-children div { display: block; }
</style>
<div class="parent">
<div>child</div>
</div>
<script>
// to show the children
$('.parent').addClass('with-children');
</script>
// My original 'goto' means to get the version
$.fn.jquery
// Another *similar* option
$().jQuery
// If there is concern that there may be multiple implementations of `$` then:
jQuery.fn.jquery
Recently I have had issues using $.fn.jquery
/$().jQuery
on a few sites so I wanted to note a third simple command to pull the jQuery version.
If you get back a version number -- usually as a string -- then jQuery is loaded and that is what version you're working with. If not loaded then you should get back
undefined
or maybe even an error.
Pretty old question and I've seen a few people that have already mentioned my answer in comments. However, I find that sometimes great answers that are left as comments can go unnoticed; especially when there are a lot of comments to an answer you may find yourself digging through piles of them looking for a gem. Hopefully this helps someone out!
Join on one-to-many relation in JPQL looks as follows:
select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName
When several properties are specified in select
clause, result is returned as Object[]
:
Object[] temp = (Object[]) em.createNamedQuery("...")
.setParameter("groupName", groupName)
.getSingleResult();
String fname = (String) temp[0];
String lname = (String) temp[1];
By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table
to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:
@Entity @Table(name = "Users")
public class User implements Serializable { ... }
When you are editing a table
Right Click -> Check Constraints -> Add -> Type something like Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly')
in expression field and a good constraint name in (Name) field.
You are done.
I had huge difficulty getting this to work for a shell variable containing a filename with whitespace. For some reason using:
file="foo bar/baz"
scp [email protected]:"'$file'"
as in @Adrian's answer seems to fail.
Turns out that what works best is using a parameter expansion to prepend backslashes to the whitespace as follows:
file="foo bar/baz"
file=${file// /\\ }
scp [email protected]:"$file"
For people who are still struggling with this error, it can also happen if you accidentally create a duplicate column with the same name. Remove duplicate columns like so:
df = df.loc[:,~df.columns.duplicated()]
If you want to iterate over a list and create a new list with "transformed" objects, you should use the map()
function of stream + collect()
. In the following example I find all people with the last name "l1" and each person I'm "mapping" to a new Employee instance.
public class Test {
public static void main(String[] args) {
List<Person> persons = Arrays.asList(
new Person("e1", "l1"),
new Person("e2", "l1"),
new Person("e3", "l2"),
new Person("e4", "l2")
);
List<Employee> employees = persons.stream()
.filter(p -> p.getLastName().equals("l1"))
.map(p -> new Employee(p.getName(), p.getLastName(), 1000))
.collect(Collectors.toList());
System.out.println(employees);
}
}
class Person {
private String name;
private String lastName;
public Person(String name, String lastName) {
this.name = name;
this.lastName = lastName;
}
// Getter & Setter
}
class Employee extends Person {
private double salary;
public Employee(String name, String lastName, double salary) {
super(name, lastName);
this.salary = salary;
}
// Getter & Setter
}
Modifications to sys.path
only apply for the life of that Python interpreter. If you want to do it permanently you need to modify the PYTHONPATH
environment variable:
PYTHONPATH="/Me/Documents/mydir:$PYTHONPATH"
export PYTHONPATH
Note that PATH
is the system path for executables, which is completely separate.
**You can write the above in ~/.bash_profile
and the source it using source ~/.bash_profile
One way to do it :
FileStream stream = File.Open(@"c:\working\test.xls", FileMode.Open, FileAccess.Read);
IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
excelReader.IsFirstRowAsColumnNames = true;
DataSet result = excelReader.AsDataSet();
The result.Tables
contains the sheets and the result.tables[0].Rows
contains the cell rows.
<script>
function getSummary(id)
{
$.ajax({
type: "GET",
url: 'Your URL',
data: "id=" + id, // appears as $_GET['id'] @ your backend side
success: function(data) {
// data is ur summary
$('#summary').html(data);
}
});
}
</script>
And add onclick
event in your lists
<a onclick="getSummary('1')">View Text</a>
<div id="#summary">This text will be replaced when the onclick event (link is clicked) is triggered.</div>
In the layout (app/design/frontend/your_theme/layout/default.xml):
<default>
<cms_page> <!-- need to be redefined for your needs -->
<reference name="content">
<block type="cms/block" name="cms_newest_product" as="cms_newest_product">
<action method="setBlockId"><block_id>newest_product</block_id></action>
</block>
</reference>
</cms_page>
</default>
In your phtml template:
<?php echo $this->getChildHtml('newest_product'); ?>
Don't forget about cache cleaning.
I think it help.
For 32 bit DLLS in Windows 64 bit platforms:
c:\windows\sysWOW64\
In the CMD window:
CD c:\windows\sysWOW64\
regsvr32 whatever.dll
You will then be executing the 32-bit regsvr (c:\windows\sysWOW64\regsvr.exe
) on a 32 bit dll
I was facing the similar problem, but instead of one all of my pods were not ready and displaying Ready status 0/1 Something like

From the doc for path.resolve
:
The resulting path is normalized and trailing slashes are removed unless the path is resolved to the root directory.
But path.join
keeps trailing slashes
So
__dirname = '/';
path.resolve(__dirname, 'foo/'); // '/foo'
path.join(__dirname, 'foo/'); // '/foo/'
You can also check the default buffer size by calling the read only DEFAULT_BUFFER_SIZE attribute from io module.
import io
print (io.DEFAULT_BUFFER_SIZE)
You can simply use:
#contentInfo_new br {display:none;}
Looping through an array of objects is a pretty fundamental functionality. This is what works for me.
var person = [];_x000D_
person[0] = {_x000D_
firstName: "John",_x000D_
lastName: "Doe",_x000D_
age: 60_x000D_
};_x000D_
_x000D_
var i, item;_x000D_
_x000D_
for (i = 0; i < person.length; i++) {_x000D_
for (item in person[i]) {_x000D_
document.write(item + ": " + person[i][item] + "<br>");_x000D_
}_x000D_
}
_x000D_
Speaking from a PC user - Reboot.
Honestly, it worked for me. I've solved two strange git issues I thought were corruptions this way.
In addition to what John Skeet said, here's an overview of the Java 7 project. It includes a list and description of the features.
Note: JDK 7 was released on July 28, 2011, so you should now go to the official java SE site.
It's worth noting that Java can overload a method such as abs
so that it works with an integer or a double. In C, overloading doesn't exist, so you need different functions for integer versus double.
In the accepted answer bobince got it right: validating only the scheme name, ://, and spaces and double quotes is usually enough. Here is how the validation can be implemented in JavaScript:
var url = 'http://www.google.com';
var valid = /^(ftp|http|https):\/\/[^ "]+$/.test(url);
// true
or
var r = /^(ftp|http|https):\/\/[^ "]+$/;
r.test('http://www.goo le.com');
// false
or
var url = 'http:www.google.com';
var r = new RegExp(/^(ftp|http|https):\/\/[^ "]+$/);
r.test(url);
// false

If your Service is started by your app then actually your service is running on main process. so when app is killed service will also be stopped. So what you can do is, send broadcast from onTaskRemoved
method of your service as follows:
Intent intent = new Intent("com.android.ServiceStopped");
sendBroadcast(intent);
and have an broadcast receiver which will again start a service. I have tried it. service restarts from all type of kills.
in your first example a = b = c = [1, 2, 3]
you are really saying:
'a' is the same as 'b', is the same as 'c' and they are all [1, 2, 3]
If you want to set 'a' equal to 1, 'b' equal to '2' and 'c' equal to 3, try this:
a, b, c = [1, 2, 3]
print(a)
--> 1
print(b)
--> 2
print(c)
--> 3
Hope this helps!
Since .net45 you can use the LeaveOpen
constructor argument of StreamWriter
and still use the using
statement. Example:
using (var ms = new MemoryStream())
{
using (var sw = new StreamWriter(ms, Encoding.UTF8, 1024, true))
{
sw.WriteLine("data");
sw.WriteLine("data 2");
}
ms.Position = 0;
using (var sr = new StreamReader(ms))
{
Console.WriteLine(sr.ReadToEnd());
}
}
Use the children funcion of jQuery.
$("#text-field").keydown(function(event) {
if($('#popup').children('p.filled-text').length > 0) {
console.log("Found");
}
});
$.children('').length
will return the count of child elements which match the selector.
With Eclipse Collections, you can do the following if you have a list of type java.util.List<Integer>
:
List<Integer> integers = Lists.mutable.with(1, 2, 3, 4, 5);
int[] ints = LazyIterate.adapt(integers).collectInt(i -> i).toArray();
Assert.assertArrayEquals(new int[]{1, 2, 3, 4, 5}, ints);
If you already have an Eclipse Collections type like MutableList
, you can do the following:
MutableList<Integer> integers = Lists.mutable.with(1, 2, 3, 4, 5);
int[] ints = integers.asLazy().collectInt(i -> i).toArray();
Assert.assertArrayEquals(new int[]{1, 2, 3, 4, 5}, ints);
Note: I am a committer for Eclipse Collections
you can use this trick to run tomcat using cmd and directly by tomcat bin folder.
1. set the path of jdk.
2.
To set path. go to Desktop and right click on computer icon. Click the Properties
go to Advance System Settings.
then Click Advance to Environment variables.
Click new and set path AS,
in the column Variable name=JAVA_HOME
Variable Value=C:\Program Files\Java\jdk1.6.0_19
Click ok ok.
now path is stetted.
3.
Go to tomcat folder where you installed the tomcat. go to bin folder. there are two window batch files.
1.Startup
2.Shutdown.
By using cmd if you installed the tomcate in D Drive
type on cmd screen
D:
Cd tomcat\bin then type Startup.
4. By clicking them you can start and stop the tomcat.
5.
Final step.
if you start and want to check it.
open a Browser in URL bar type.
**HTTP://localhost:8080/**
For Linux; getchar() is all you need.
If you are on Windows, check out the following, it is exactly what you need!
kbit() function
For example, see how it works in the following program;
//any_key.c
#include <stdio.h>
#include <conio.h>
int main(){
//code here
printf ("Press any key to continue . . .\n");
while (1) if (kbhit()) break;
//code here
return 0;
}
When I compile and run the program, this is what I see.
Only when user presses just one key from the keyboard, kbhit() returns 1.
You could try the somewhat dangerous: taskkill /IM cmd.exe
..dangerous bcz that will kill the cmd that is open and any cmd's opened before it.
Or add a verification to confirm that you had the right cmd.exe and then kill it via PID, such as this:
set loc=%time%%random%
title=%loc%
for /f "tokens=2 delims= " %%A in ('tasklist /v ^| findstr /i "%loc%"') do (taskkill /PID %%A)
Substitute (pslist &&A)
or (tasklist /FI "PID eq %%A")
for the (taskkill /PID %%A)
if you want to check it first (and maybe have pstools installed).

By default there will be no branches listed and pops up only after some file is placed. You don't have to worry much about it. Just run all your commands like creating folder structures, adding/deleting files, commiting files, pushing it to server or creating branches. It works seamlessly without any issue.
Personally I find
if (id in tutorTimes === false) { ... }
easier to read than

but both will work.
Try using this code for v3:

Here is an example that verifies an exception is thrown, and uses Truth to make assertions on the exception message:
public class FooTest {
@Test
public void doStuffThrowsIndexOutOfBoundsException() {
Foo foo = new Foo();
IndexOutOfBoundsException e = assertThrows(
IndexOutOfBoundsException.class, foo::doStuff);
assertThat(e).hasMessageThat().contains("woops!");
}
}
The advantages over the approaches in the other answers are:
throws
clauseA similar method will be added to org.junit Assert
in JUnit 4.13.
What the others said, but also note that you do not have to declare the destructor virtual in the derived class. Once you declare a destructor virtual, as you do in the base class, all derived destructors will be virtual whether you declare them so or not. In other words:
struct A {
virtual ~A() {}
};
struct B : public A {
virtual ~B() {} // this is virtual
};
struct C : public A {
~C() {} // this is virtual too
};
There are too much too long anwers in a foreign language. So I'll try to make it short.
If you write from . import module
, opposite to what you think, module
will not be imported from current directory, but from the top level of your package! If you run .py file as a script, it simply doesn't know where the top level is and thus refuses to work.
If you start it like this py -m package.module
from the directory above package
, then python knows where the top level is. That's very similar to java: java -cp bin_directory package.class
this.props.history.goBack();
This is the correct solution for react-router v4
But one thing you should keep in mind is that you need to make sure this.props.history is existed.
That means you need to call this function this.props.history.goBack();
inside the component that is wrapped by < Route/>
If you call this function in a component that deeper in the component tree, it will not work.
EDIT:
If you want to have history object in the component that is deeper in the component tree (which is not wrapped by < Route>), you can do something like this:
...
import {withRouter} from 'react-router-dom';
class Demo extends Component {
...
// Inside this you can use this.props.history.goBack();
}
export default withRouter(Demo);
You could use Pattern/Matcher. From the Matcher javadocs:
Pattern p = Pattern.compile("cat");
Matcher m = p.matcher("one cat two cats in the yard");
StringBuffer sb = new StringBuffer();
while (m.find()) {
m.appendReplacement(sb, "dog");
}
m.appendTail(sb);
System.out.println(sb.toString());
go to sdk folder and right click on SDK manager and run with administrator and enjoy installing.
Use DateTime::createFromFormat like this :
$date = DateTime::createFromFormat('m/d/Y H:i:s', $input_string.' 00:00:00');
$mysql_date_string = $date->format('Y-m-d H:i:s');
You can adapt this to any input format, whereas strtotime() will assume you're using the US date format if you use /, even if you're not.
The added 00:00:00 is because createFromFormat will use the current date to fill missing data, ie : it will take the current hour:min:sec and not 00:00:00 if you don't precise it.
server {
server_name example.com;
root /path/to/root;
location / {
# bla bla
}
location /demo {
alias /path/to/root/production/folder/here;
}
}
If you need to use try_files
inside /demo
you'll need to replace alias
with a root
and do a rewrite because of the bug explained here
I want change default directory dumpfile.
You could create a new directory and give it required privileges, for example:
SQL> CREATE DIRECTORY dmpdir AS '/opt/oracle';
Directory created.
SQL> GRANT read, write ON DIRECTORY dmpdir TO scott;
Grant succeeded.
To use the newly created directory, you could just add it as a parameter:
DIRECTORY=dmpdir
Oracle introduced a default directory from 10g R2, called DATA_PUMP_DIR, that can be used. To check the location, you could look into dba_directories:
SQL> select DIRECTORY_NAME, DIRECTORY_PATH from dba_directories where DIRECTORY_NAME = 'DATA_PUMP_DIR';
DIRECTORY_NAME DIRECTORY_PATH
-------------------- --------------------------------------------------
DATA_PUMP_DIR C:\app\Lalit/admin/orcl/dpdump/

I was getting the same error and used below below link to get help:
https://nodejs.org/api/http.html#http_http_request_options_callback
I was not having in my code:

once added above req.end();
line, I was able to get rid of the error and worked fine for me.
With newer versions of client tools, there are multiple options to format the query output. The rest is to spool it to a file or save the output as a file depending on the client tool. Here are few of the ways:
Using the SQL*Plus commands you could format to get your desired output. Use SPOOL to spool the output to a file.
For example,
SQL> SET colsep ,
SQL> SET pagesize 20
SQL> SET trimspool ON
SQL> SET linesize 200
SQL> SELECT * FROM scott.emp;

Alternatively, you could use the new /*csv*/
hint in SQL Developer.
/*csv*/
For example, in my SQL Developer Version 3.2.20.10:
Now you could save the output into a file.
New in SQL Developer version 4.1, use the following just like sqlplus command and run as script. No need of the hint in the query.
SET SQLFORMAT csv
Now you could save the output into a file.
I think that one important point that was not mentioned in the previous answers is that, if not explicitly indicated, the matlab interpreter will remain open.
Therefore, to the answer of @hkBattousai I will add the exit
command:
"C:\<a long path here>\matlab.exe" -nodisplay -nosplash -nodesktop -r "run('C:\<a long path here>\mfile.m');exit;"
python -c 'from myfile import hello; hello()'
where myfile
must be replaced with the basename of your Python script. (E.g., myfile.py
becomes myfile
).
However, if hello()
is your "permanent" main entry point in your Python script, then the usual way to do this is as follows:
def hello():
print "Hi :)"
if __name__ == "__main__":
hello()
This allows you to execute the script simply by running python myfile.py
or python -m myfile
.
Some explanation here: __name__
is a special Python variable that holds the name of the module currently being executed, except when the module is started from the command line, in which case it becomes "__main__"
.
sp_executesql
is more likely to promote query plan reuse. When using sp_executesql
, parameters are explicitly identified in the calling signature. This excellent article descibes this process.
The oft cited reference for many aspects of dynamic sql is Erland Sommarskog's must read: "The Curse and Blessings of Dynamic SQL".
I encountered this problem when upgrading existing projects from VS2008 to VS2012. I found that two projects (the only two that I created) were targeting different .Net Frameworks (3.5 and 4.0). I resolved this on the Application tab of the projects by making sure that both projects had ".NET Framework 4" in the Target Framework box.
In .NET 4.5, you can use the CultureInfo.DefaultThreadCurrentCulture
property to change the culture of an AppDomain.
For versions prior to 4.5 you have to use reflection to manipulate the culture of an AppDomain. There is a private static field on CultureInfo
(m_userDefaultCulture
in .NET 2.0 mscorlib, s_userDefaultCulture
in .NET 4.0 mscorlib) that controls what CurrentCulture
returns if a thread has not set that property on itself.
This does not change the native thread locale and it is probably not a good idea to ship code that changes the culture this way. It may be useful for testing though.
I had the same issue to connect an SQL_server 2008 to an SQL_server 2016 hosted in a remote server. @Domnic answer didn't worked for me straightforward. I write my tweaked solution here as I think it may be useful for someone else.
An extended answer for remote IP db connections:
Step 1: Link servers
EXEC sp_addlinkedserver @server='SRV_NAME',
@srvproduct=N'',
@provider=N'SQLNCLI',
@datasrc=N'aaa.bbb.ccc.ddd';
EXEC sp_addlinkedsrvlogin 'SRV_NAME', 'false', NULL, 'your_remote_db_login_user', 'your_remote_db_login_password'
...where SRV_NAME
is an invented name. We will use it to refer to the remote server from our queries. aaa.bbb.ccc.ddd
is the ip address of the remote server hosting your SQLserver DB.
Step 2: Run your queries For instance:
SELECT * FROM [SRV_NAME].your_remote_db_name.dbo.your_table
...and that's it!
Syntax details: sp_addlinkedserver and sp_addlinkedsrvlogin
You have an error in you script tag construction, this:
<script language="JavaScript" type="text/javascript" script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>
Should look like this:
<script language="JavaScript" type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>
You have a 'script' word lost in the middle of your script tag. Also you should remove the http:// to let the browser decide whether to use HTTP or HTTPS.
UPDATE
But your main error is that you are including jQuery UI (ONLY) you must include jQuery first! jQuery UI and jQuery are used together, not in separate. jQuery UI depends on jQuery. You should put this line before jQuery UI:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
To produce patch for several commits, you should use format-patch
git command, e.g.
git format-patch -k --stdout R1..R2
This will export your commits into patch file in mailbox format.
To generate patch for the last commit, run:
git format-patch -k --stdout HEAD^
Then in another repository apply the patch by am
git command, e.g.
git am -3 -k file.patch
See: man git-format-patch
and git-am
.
- Where does
user.id
go afterpassport.serializeUser
has been called?
The user id (you provide as the second argument of the done
function) is saved in the session and is later used to retrieve the whole object via the deserializeUser
function.
serializeUser
determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}
. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}
- We are calling
passport.deserializeUser
right after it where does it fit in the workflow?
The first argument of deserializeUser
corresponds to the key of the user object that was given to the done
function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc).
In deserializeUser
that key is matched with the in memory array / database or any data resource.
The fetched object is attached to the request object as req.user
Visual Flow
passport.serializeUser(function(user, done) {
done(null, user.id);
}); ¦

Suppose you made changes to multiple files, like:
But you want to commit only changes of File1 and File3.
There are two ways for doing this:
1.Stage only these two files, using:
git add file1 file2
then, commit
git commit -m "your message"
then push,
git push
2.Direct commit
git commit file1 file3 -m "my message"
then push,
git push
Actually first method is useful in case if we are modifying files regularly and staging them --> Large Projects, generally Live projects.
But if we are modifying files and not staging them then we can do direct commit --> Small projects
Render is
def render(request, *args, **kwargs):
""" Simple wrapper for render_to_response. """
kwargs['context_instance'] = RequestContext(request)
return render_to_response(*args, **kwargs)
So there is really no difference between render_to_response
except it wraps your context making the template pre-processors work.
Direct to template is a generic view.
There is really no sense in using it here because there is overhead over render_to_response
in the form of view function.
The best solution I've been able to find consists of these steps:
mvn-repo
to host your maven artifacts.mvn-repo
as a maven repository.There are several benefits to using this approach:
mvn-repo
, much like github pages are kept in a separate branch called gh-pages
(if you use github pages)gh-pages
if you're using them.mvn deploy
as you normally wouldThe typical way you deploy artifacts to a remote maven repo is to use mvn deploy
, so let's patch into that mechanism for this solution.
First, tell maven to deploy artifacts to a temporary staging location inside your target directory. Add this to your pom.xml
:
<distributionManagement>
<repository>
<id>internal.repo</id>
<name>Temporary Staging Repository</name>
<url>file://${project.build.directory}/mvn-repo</url>
</repository>
</distributionManagement>
<plugins>
<plugin>
<artifactId>maven-deploy-plugin</artifactId>
<version>2.8.1</version>
<configuration>
<altDeploymentRepository>internal.repo::default::file://${project.build.directory}/mvn-repo</altDeploymentRepository>
</configuration>
</plugin>
</plugins>
Now try running mvn clean deploy
. You'll see that it deployed your maven repository to target/mvn-repo
. The next step is to get it to upload that directory to GitHub.
Add your authentication information to ~/.m2/settings.xml
so that the github site-maven-plugin
can push to GitHub:
<!-- NOTE: MAKE SURE THAT settings.xml IS NOT WORLD READABLE! -->
<settings>
<servers>
<server>
<id>github</id>
<username>YOUR-USERNAME</username>
<password>YOUR-PASSWORD</password>
</server>
</servers>
</settings>
(As noted, please make sure to chmod 700 settings.xml
to ensure no one can read your password in the file. If someone knows how to make site-maven-plugin prompt for a password instead of requiring it in a config file, let me know.)
Then tell the GitHub site-maven-plugin
about the new server you just configured by adding the following to your pom:
<properties>
<!-- github server corresponds to entry in ~/.m2/settings.xml -->
<github.global.server>github</github.global.server>
</properties>
Finally, configure the site-maven-plugin
to upload from your temporary staging repo to your mvn-repo
branch on Github:
<build>
<plugins>
<plugin>
<groupId>com.github.github</groupId>
<artifactId>site-maven-plugin</artifactId>
<version>0.11</version>
<configuration>
<message>Maven artifacts for ${project.version}</message> <!-- git commit message -->
<noJekyll>true</noJekyll> <!-- disable webpage processing -->
<outputDirectory>${project.build.directory}/mvn-repo</outputDirectory> <!-- matches distribution management repository url above -->
<branch>refs/heads/mvn-repo</branch> <!-- remote branch name -->
<includes><include>**/*</include></includes>
<repositoryName>YOUR-REPOSITORY-NAME</repositoryName> <!-- github repo name -->
<repositoryOwner>YOUR-GITHUB-USERNAME</repositoryOwner> <!-- github username -->
</configuration>
<executions>
<!-- run site-maven-plugin's 'site' target as part of the build's normal 'deploy' phase -->
<execution>
<goals>
<goal>site</goal>
</goals>
<phase>deploy</phase>
</execution>
</executions>
</plugin>
</plugins>
</build>
The mvn-repo
branch does not need to exist, it will be created for you.
Now run mvn clean deploy
again. You should see maven-deploy-plugin "upload" the files to your local staging repository in the target directory, then site-maven-plugin committing those files and pushing them to the server.

Visit github.com in your browser, select the mvn-repo
branch, and verify that all your binaries are now there.
Congratulations!
You can now deploy your maven artifacts to a poor man's public repo simply by running mvn clean deploy
.
There's one more step you'll want to take, which is to configure any poms that depend on your pom to know where your repository is. Add the following snippet to any project's pom that depends on your project:
<repositories>
<repository>
<id>YOUR-PROJECT-NAME-mvn-repo</id>
<url>https://github.com/YOUR-USERNAME/YOUR-PROJECT-NAME/raw/mvn-repo/</url>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</repository>
</repositories>
Now any project that requires your jar files will automatically download them from your github maven repository.
Edit: to avoid the problem mentioned in the comments ('Error creating commit: Invalid request. For 'properties/name', nil is not a string.'), make sure you state a name in your profile on github.
Although you can use the
{{ game.gameDate|date('Y-m-d') }}
approach, keep in mind that this version does not honor the user locale, which should not be a problem with a site used by only users of one nationality. International users should display the game date totally different, like extending the \DateTime
class, and adding a __toString()
method to it that checks the locale and acts accordingly.
Edit:
As pointed out by @Nic in a comment, if you use the Intl extension of Twig, you will have a localizeddate
filter available, which shows the date in the user’s locale. This way you can drop my previous idea of extending \DateTime
.
The pathlib
library is really great for working with files. You can do a recursive glob on a Path
object like so.
from pathlib import Path
for elem in Path('/path/to/my/files').rglob('*.*'):
print(elem)
For me, .git/refs/origin/master
had got corrupt.
I did the following, which fixed the problem for me.
rm .git/refs/remotes/origin/master
git fetch
git branch --set-upstream-to=origin/master
Up front .. I am a Hudson committer and author of the Hudson book, but I was not involved in the whole split of the projects.
In any case here is my advice:
Check out both and see what fits your needs better.
Hudson is going to complete the migration to be a top level Eclipse projects later this year and has gotten a whole bunch of full time developers, QA and others working on the project. It is still going strong and has a lot of users and with being the default CI server at Eclipse it will continue to serve the needs of many Java developers. Looking at the roadmap and plans for the future you can see that after the Maven 3 integration accomplished with the 2.1.0 release a whole bunch of other interesting feature are ahead.
Jenkins on the other side has won over many original Hudson users and has a large user community across multiple technologies and also has a whole bunch of developers working on it.
At this stage both CI servers are great tools to use and depending on your needs in terms of technology to integrate with one or the other might be better. Both products are available as open source and you can get commercial support from various companies for both.
In any case .. if you are not using a CI server yet.. start now with either of them and you will see huge benefits.
Update Jan 2013: After a long process of IP cleanup and further improvements Hudson 3.0 as the first Eclipse foundation approved release is now available.
If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:
var data = context.MyEntities.AsNoTracking().Where(...).ToList();
As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.

Recordsets have two important properties when looping through data, EOF (End-Of-File) and BOF (Beginning-Of-File). Recordsets are like tables and when you loop through one, you are literally moving from record to record in sequence. As you move through the records the EOF property is set to false but after you try and go past the last record, the EOF property becomes true. This works the same in reverse for the BOF property.
These properties let us know when we have reached the limits of a recordset.
As IE9 does not support CSS3 text-shadow
, I would just use the filter property for IE instead. Live example: http://jsfiddle.net/dmM2S/
text-shadow:1px 1px 1px red; /* CSS3 */
can be replaced with
filter: Shadow(Color=red, Direction=130, Strength=1); /* IE Proprietary Filter*/
You can get the results to be very similar.
I fixed it by removing float:left
, and adding display:inline-block
instead. Haven't used it for images, but should work fine, there, too.
In a POST request, the parameters are sent in the body of the request, that's why you don't see them in the URL.
If you want to see them, change

to
type: 'GET',
Note that browsers have development tools which lets you see the complete requests that your code issues. In Chrome, it's in the "Network" panel.

Much like setState in Class components created by extending React.Component
or React.PureComponent
, the state update using the updater provided by useState
hook is also asynchronous, and will not be reflected immediately.
Also, the main issue here is not just the asynchronous nature but the fact that state values are used by functions based on their current closures, and state updates will reflect in the next re-render by which the existing closures are not affected, but new ones are created. Now in the current state, the values within hooks are obtained by existing closures, and when a re-render happens, the closures are updated based on whether the function is recreated again or not.
Even if you add a setTimeout
the function, though the timeout will run after some time by which the re-render would have happened, the setTimeout
will still use the value from its previous closure and not the updated one.
setMovies(result);
console.log(movies) // movies here will not be updated
If you want to perform an action on state update, you need to use the useEffect hook, much like using componentDidUpdate
in class components since the setter returned by useState doesn't have a callback pattern
useEffect(() => {
// action on update of movies
}, [movies]);
As far as the syntax to update state is concerned, setMovies(result)
will replace the previous movies
value in the state with those available from the async request.
However, if you want to merge the response with the previously existing values, you must use the callback syntax of state updation along with the correct use of spread syntax like
setMovies(prevMovies => ([...prevMovies, ...result]));
The window
binding refers to a built-in object provided by the browser. It represents the browser window that contains the document
. Calling its addEventListener
method registers the second argument (callback function) to be called whenever the event described by its first argument occurs.

Following points should be noted before select window or document to addEventListners
window
or document
but
some events like resize
, and other events related to loading
,
unloading
, and opening/closing
should all be set on the window.You can use the parameter -f
(or --file
) and specify the path to your pom file, e.g. mvn -f /path/to/pom.xml
This runs maven "as if" it were in /path/to

Use %in%
as follows
A$C %in% B$C
Which will tell you which values of column C of A are in B.
What is returned is a logical vector. In the specific case of your example, you get:
A$C %in% B$C
# [1] TRUE FALSE TRUE TRUE
Which you can use as an index to the rows of A
or as an index to A$C
to get the actual values:
# as a row index
A[A$C %in% B$C, ] # note the comma to indicate we are indexing rows
# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4 # returns all values of A$C that are in B$C
We can negate it too:
A$C[!A$C %in% B$C]
[1] 2 # returns all values of A$C that are NOT in B$C
2 %in% B$C # "is the value 2 in B$C ?"
# FALSE
A$C[2] %in% B$C # "is the 2nd element of A$C in B$C ?"
# FALSE
When searching folders where you might get an error based on security (e.g. C:\Users
), use the following command:
Get-ChildItem -Path V:\Myfolder -Filter CopyForbuild.bat -Recurse -ErrorAction SilentlyContinue -Force
Threads are absolutely not the answer here. They will provide both process and kernel bottlenecks, as well as throughput limits that are not acceptable if the overall goal is "the fastest way".
A little bit of twisted
and its asynchronous HTTP
client would give you much better results.
Here's the form I've been using in all my code.
private void DoGUISwitch()
{
Invoke( ( MethodInvoker ) delegate {
object1.Visible = true;
object2.Visible = false;
});
}
I've based this on the blog entry here. I have not had this approach fail me, so I see no reason to complicate my code with a check of the InvokeRequired
property.
Hope this helps.
I learnt a easy way from code example of http://tutorial.symblog.co.uk/
1) notice the ZendeskBlueFormBundle and file location
# myproject/app/config/config.yml
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: @ZendeskBlueFormBundle/Resources/config/config.yml }
framework:
2) notice Zendesk_BlueForm.emails.contact_email and file location
# myproject/src/Zendesk/BlueFormBundle/Resources/config/config.yml
parameters:
# Zendesk contact email address
Zendesk_BlueForm.emails.contact_email: [email protected]
3) notice how i get it in $client and file location of controller
# myproject/src/Zendesk/BlueFormBundle/Controller/PageController.php
public function blueFormAction($name, $arg1, $arg2, $arg3, Request $request)
{
$client = new ZendeskAPI($this->container->getParameter("Zendesk_BlueForm.emails.contact_email"));
...
}
bw.newLine();
cannot ensure compatibility with all systems.
If you are sure it is going to be opened in windows, you can format it to windows newline.
If you are already using native unix commands, try unix2dos
and convert teh already generated file to windows format and then send the mail.
If you are not using unix commands and prefer to do it in java, use ``bw.write("\r\n")` and if it does not complicate your program, have a method that finds out the operating system and writes the appropriate newline.
Call me simple but I just declared a Variant and split the responsetext from my REST GET on the quote comma quote between each item, then got the value I wanted by looking for the last quote with InStrRev. I'm sure that's not as elegant as some of the other suggestions but it works for me.
varLines = Split(.responsetext, """,""")
strType = Mid(varLines(8), InStrRev(varLines(8), """") + 1)
Bearer tokens look like this:
curl -H "Authorization: Bearer <ACCESS_TOKEN>" http://www.example.com
@RequestParam
annotated parameters get linked to specific Servlet request parameters. Parameter values are converted to the declared method argument type.
This annotation indicates that a method parameter should be bound to a web request parameter.
For example Angular request for Spring RequestParam(s) would look like that:
$http.post('http://localhost:7777/scan/l/register?username="Johny"&password="123123"&auth=true')
.success(function (data, status, headers, config) {
...
})
Endpoint with RequestParam:
@RequestMapping(method = RequestMethod.POST, value = "/register")
public Map<String, String> register(Model uiModel,
@RequestParam String username,
@RequestParam String password,
@RequestParam boolean auth,
HttpServletRequest httpServletRequest) {...
@RequestBody
annotated parameters get linked to the HTTP request body. Parameter values are converted to the declared method argument type using HttpMessageConverters.
This annotation indicates a method parameter should be bound to the body of the web request.
For example Angular request for Spring RequestBody would look like that:
$scope.user = {
username: "foo",
auth: true,
password: "bar"
};
$http.post('http://localhost:7777/scan/l/register', $scope.user).
success(function (data, status, headers, config) {
...
})
Endpoint with RequestBody:
@RequestMapping(method = RequestMethod.POST, produces = "application/json",
value = "/register")
public Map<String, String> register(Model uiModel,
@RequestBody User user,
HttpServletRequest httpServletRequest) {...
Hope this helps.
You can use Manifold's @Jailbreak for direct, type-safe Java reflection:
@Jailbreak Foo foo = new Foo();
foo.callMe();
public class Foo {
private void callMe();
}
@Jailbreak
unlocks the foo
local variable in the compiler for direct access to all the members in Foo
's hierarchy.
Similarly you can use the jailbreak() extension method for one-off use:
foo.jailbreak().callMe();
Through the jailbreak()
method you can access any member in Foo
's hierarchy.
In both cases the compiler resolves the method call for you type-safely, as if a public method, while Manifold generates efficient reflection code for you under the hood.
Alternatively, if the type is not known statically, you can use Structural Typing to define an interface a type can satisfy without having to declare its implementation. This strategy maintains type-safety and avoids performance and identity issues associated with reflection and proxy code.

I had the same problem and my first <p>
element which was at the top of the page and also had a browser webkit default margin. This was pushing my entire div down which had the same effect you were talking about so watch out for any text-based elements that are at the very top of the page.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>My Website</title>
</head>
<body style="margin:0;">
<div id="image" style="background: url(pixabay-cleaning-kids-720.jpg)
no-repeat; width: 100%; background-size: 100%;height:100vh">
<p>Text in Paragraph</p>
</div>
</div>
</body>
</html>
So just remember to check all child elements not only the html and body tags.
There are many ways. Here are at least five:

#include <alloca.h>
#include <string>
#include <cstring>
int main()
{
std::string s0;
const char *s1;
char *s2;
char *s3;
char *s4;
char *s5;
// This is the initial C++ string.
s0 = "hello";
// Method #1: Just use "c_str()" method to obtain a pointer to a
// null-terminated C string stored in std::string object.
// Be careful though because when `s0` goes out of scope, s1 points
// to a non-valid memory.
s1 = s0.c_str();
// Method #2: Allocate memory on stack and copy the contents of the

// the memory is invalidated.
s2 = (char *)alloca(s0.size() + 1);
memcpy(s2, s0.c_str(), s0.size() + 1);
// Method #3: Allocate memory dynamically and copy the content of the
// original string. The memory will be valid until you explicitly
// release it using "free". Forgetting to release it results in memory
// leak.
s3 = (char *)malloc(s0.size() + 1);
memcpy(s3, s0.c_str(), s0.size() + 1);
// Method #4: Same as method #3, but using C++ new/delete operators.
s4 = new char[s0.size() + 1];
memcpy(s4, s0.c_str(), s0.size() + 1);
// Method #5: Same as 3 but a bit less efficient..

If notepad is already started, you should write:
// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);
//...
Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
}
GetProcessesByName
returns an array of processes, so you should get the first one (or find the one you want).
If you want to start notepad
and send the key, you should write:
Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
The only situation in which the code may not work is when notepad
is started as Administrator and your application is not.
I have also faced this problem in my project. AVD is not able to reload assets,lib,res and etc folder contexts.
problem :
Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl
.
Then,I created new projects and copied MainActivity.java
,activity_main.xml
, drawable context.
Then delete old project from package explore,restart your Eclipse and AVD.
My project is now working properly.... :)
I hope this steps will help u little bit folks..!!
I was stuck here too. copy-webpack-plugin worked for me.
However, 'copy-webpack-plugin' was not necessary in my case (i learned later).
webpack ignores root paths
example
<img src="/images/logo.png'>
Hence, to make this work without using 'copy-webpack-plugin' use '~' in paths
<img src="~images/logo.png'>
'~' tells webpack to consider 'images' as a module
note: you might have to add the parent directory of images directory in
resolve: {
modules: [
'parent-directory of images',
'node_modules'
]
}
Just append a div
with that class to body
, then remove it when you're done:
// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);
// Remove it (later)
$(".modal-backdrop").remove();
Live Example:
$("input").click(function() {_x000D_
var bd = $('<div class="modal-backdrop"></div>');_x000D_
bd.appendTo(document.body);_x000D_
setTimeout(function() {_x000D_
bd.remove();_x000D_
}, 2000);_x000D_
});

The solution I end up using most is based off of Tomas Petricek's answer. I usually want to do something with both the attribute and property.
var props = from p in this.GetType().GetProperties()
let attr = p.GetCustomAttributes(typeof(MyAttribute), true)
where attr.Length == 1
select new { Property = p, Attribute = attr.First() as MyAttribute};
If you have access to on the server, consider setting headers as answered in this more general question.
Content-Type: application/octet-stream
Content-Disposition: attachment;filename=\"filename.xxx\"
Reading the comments on that answer, it is advisable to use a more specific Content-Type than octet-stream.
Just tried this recently and when trying to select the JDK... /System/Library/Java/JavaVirtualMachines/
appears as empty when opening&selecting through IntelliJ. Therefore i couldn't select the JDK...
I've found that to workaround this, when the finder windows open (pressing [+] JDK) just use the shortcut Shift + CMD + G to specify the path. (/System/Library/Java/JavaVirtualMachines/1.6.0.jdk
in my case)
And voila, IntelliJ can find everything from that point on.
Let's assume our application uses the following Post
, PostComment
, PostDetails
, and Tag
entities, which form a one-to-many, one-to-one, and many-to-many table relationships:
The hibernate-jpamodelgen
tool provided by Hibernate ORM can be used to scan the project entities and generate the JPA Criteria Metamodel. All you need to do is add the following annotationProcessorPath
to the maven-compiler-plugin
in the Maven pom.xml
configuration file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${maven-compiler-plugin.version}</version>
<configuration>
<annotationProcessorPaths>
<annotationProcessorPath>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-jpamodelgen</artifactId>
<version>${hibernate.version}</version>
</annotationProcessorPath>
</annotationProcessorPaths>
</configuration>
</plugin>
Now, when the project is compiled, you can see that in the target
folder, the following Java classes are generated:
> tree target/generated-sources/
target/generated-sources/
+-- annotations
+-- com
+-- vladmihalcea
+-- book
+-- hpjp
+-- hibernate
+-- forum
¦ +-- PostComment_.java
¦ +-- PostDetails_.java
¦ +-- Post_.java
¦ +-- Tag_.java
If the Tag
entity is mapped as follows:
@Entity
@Table(name = "tag")
public class Tag {
@Id
private Long id;
private String name;
//Getters and setters omitted for brevity
}
The Tag_
Metamodel class is generated like this:
@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(Tag.class)
public abstract class Tag_ {
public static volatile SingularAttribute<Tag, String> name;
public static volatile SingularAttribute<Tag, Long> id;
public static final String NAME = "name";
public static final String ID = "id";
}
The SingularAttribute
is used for the basic id
and name
Tag
JPA entity attributes.
The Post
entity is mapped like this:
@Entity
@Table(name = "post")
public class Post {
@Id
private Long id;
private String title;
@OneToMany(
mappedBy = "post",
cascade = CascadeType.ALL,
orphanRemoval = true
)
private List<PostComment> comments = new ArrayList<>();
@OneToOne(
mappedBy = "post",
cascade = CascadeType.ALL,
fetch = FetchType.LAZY
)
@LazyToOne(LazyToOneOption.NO_PROXY)
private PostDetails details;
@ManyToMany
@JoinTable(
name = "post_tag",
joinColumns = @JoinColumn(name = "post_id"),
inverseJoinColumns = @JoinColumn(name = "tag_id")
)
private List<Tag> tags = new ArrayList<>();
//Getters and setters omitted for brevity
}
The Post
entity has two basic attributes, id
and title
, a one-to-many comments
collection, a one-to-one details
association, and a many-to-many tags
collection.
The Post_
Metamodel class is generated as follows:
@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(Post.class)
public abstract class Post_ {
public static volatile ListAttribute<Post, PostComment> comments;
public static volatile SingularAttribute<Post, PostDetails> details;
public static volatile SingularAttribute<Post, Long> id;
public static volatile SingularAttribute<Post, String> title;
public static volatile ListAttribute<Post, Tag> tags;
public static final String COMMENTS = "comments";
public static final String DETAILS = "details";
public static final String ID = "id";
public static final String TITLE = "title";
public static final String TAGS = "tags";
}
The basic id
and title
attributes, as well as the one-to-one details
association, are represented by a SingularAttribute
while the comments
and tags
collections are represented by the JPA ListAttribute
.
The PostDetails
entity is mapped like this:
@Entity
@Table(name = "post_details")
public class PostDetails {
@Id
@GeneratedValue
private Long id;
@Column(name = "created_on")
private Date createdOn;
@Column(name = "created_by")
private String createdBy;
@OneToOne(fetch = FetchType.LAZY)
@MapsId
@JoinColumn(name = "id")
private Post post;
//Getters and setters omitted for brevity
}
All entity attributes are going to be represented by the JPA SingularAttribute
in the associated PostDetails_
Metamodel class:
@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(PostDetails.class)
public abstract class PostDetails_ {
public static volatile SingularAttribute<PostDetails, Post> post;
public static volatile SingularAttribute<PostDetails, String> createdBy;
public static volatile SingularAttribute<PostDetails, Long> id;
public static volatile SingularAttribute<PostDetails, Date> createdOn;
public static final String POST = "post";
public static final String CREATED_BY = "createdBy";
public static final String ID = "id";
public static final String CREATED_ON = "createdOn";
}
The PostComment
is mapped as follows:
@Entity
@Table(name = "post_comment")
public class PostComment {
@Id
private Long id;
@ManyToOne(fetch = FetchType.LAZY)
private Post post;
private String review;
//Getters and setters omitted for brevity
}
And, all entity attributes are represented by the JPA SingularAttribute
in the associated PostComments_
Metamodel class:
@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(PostComment.class)
public abstract class PostComment_ {
public static volatile SingularAttribute<PostComment, Post> post;
public static volatile SingularAttribute<PostComment, String> review;
public static volatile SingularAttribute<PostComment, Long> id;
public static final String POST = "post";
public static final String REVIEW = "review";
public static final String ID = "id";
}
Without the JPA Metamodel, a Criteria API query that needs to fetch the PostComment
entities filtered by their associated Post
title would look like this:
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<PostComment> query = builder.createQuery(PostComment.class);
Root<PostComment> postComment = query.from(PostComment.class);
Join<PostComment, Post> post = postComment.join("post");
query.where(
builder.equal(
post.get("title"),
"High-Performance Java Persistence"
)
);
List<PostComment> comments = entityManager
.createQuery(query)
.getResultList();
Notice that we used the post
String literal when creating the Join
instance, and we used the title
String literal when referencing the Post
title
.
The JPA Metamodel allows us to avoid hard-coding entity attributes, as illustrated by the following example:
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<PostComment> query = builder.createQuery(PostComment.class);
Root<PostComment> postComment = query.from(PostComment.class);
Join<PostComment, Post> post = postComment.join(PostComment_.post);
query.where(
builder.equal(
post.get(Post_.title),
"High-Performance Java Persistence"
)
);
List<PostComment> comments = entityManager
.createQuery(query)
.getResultList();
Or, let's say we want to fetch a DTO projection while filtering the Post
title
and the PostDetails
createdOn
attributes.
We can use the Metamodel when creating the join attributes, as well as when building the DTO projection column aliases or when referencing the entity attributes we need to filter:
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Object[]> query = builder.createQuery(Object[].class);
Root<PostComment> postComment = query.from(PostComment.class);
Join<PostComment, Post> post = postComment.join(PostComment_.post);
query.multiselect(
postComment.get(PostComment_.id).alias(PostComment_.ID),
postComment.get(PostComment_.review).alias(PostComment_.REVIEW),
post.get(Post_.title).alias(Post_.TITLE)
);
query.where(
builder.and(
builder.like(
post.get(Post_.title),
"%Java Persistence%"
),
builder.equal(
post.get(Post_.details).get(PostDetails_.CREATED_BY),
"Vlad Mihalcea"
)
)
);
List<PostCommentSummary> comments = entityManager
.createQuery(query)
.unwrap(Query.class)
.setResultTransformer(Transformers.aliasToBean(PostCommentSummary.class))
.getResultList();
Cool, right?
There might be Several plugins but one may use CSS for creating button. First of all click on Source button mentioned in Editor then paste the button code over there, As I use CSS to create button and added href to it.
<p dir="ltr" style="text-align:center"><a href="https://play.google.com/store/apps/details?id=com.mobicom.mobiune&hl=en" style="background-color:#0080ff; border: none;color: white;padding: 6px 20px;text-align: center;text-decoration: none;display: inline-block;border-radius: 8px;font-size: 15px; font-weight: bold;">Open App</a></p>
This is the Button Written Open App over It. You May change the Color as i am using #0080ff (Light Blue)
You don't actually need to run a command from an xterm session, you can run it directly:
String[] arguments = new String[] {"/path/to/executable", "arg0", "arg1", "etc"};
Process proc = new ProcessBuilder(arguments).start();
If the process responds interactively to the input stream, and you want to inject values, then do what you did before:
OutputStream out = proc.getOutputStream();
out.write("command\n");
out.flush();
Don't forget the '\n' at the end though as most apps will use it to identify the end of a single command's input.
I faced the same problem. There are two types of permissions in Android:
Normal permissions are automatically approved by Android while dangerous permissions need to be approved by Android users.
Here is the strategy to get dangerous permissions in Android 6.0
Here is my case: I need to write to external storage.
First, I check if I have the permission:
...
private static final int REQUEST_WRITE_STORAGE = 112;
...
boolean hasPermission = (ContextCompat.checkSelfPermission(activity,
Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
if (!hasPermission) {
ActivityCompat.requestPermissions(parentActivity,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
REQUEST_WRITE_STORAGE);
}
Then check the user's approval:
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode)
{
case REQUEST_WRITE_STORAGE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
//reload my activity with permission granted or use the features what required the permission
} else
{
Toast.makeText(parentActivity, "The app was not allowed to write to your storage. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
}
}
}
}
You can read more about the new permission model here: https://developer.android.com/training/permissions/requesting.html
DATE_FORMAT(column name, '%Y-%m-%d %T') as dtime
Use this to avoid the error. It return the date in string format and then you can get it as a string.
resultset.getString("dtime");
This actually does NOT work. Even though you call getString. Internally mysql still tries to convert it to date first.

You must have a server-side script to handle your request, it can't be done using javascript.
To send raw data without URIencoding or escaping special characters to the php and save it as new txt
file you can send ajax request using post
method and FormData
like:
JS:
var data = new FormData();
data.append("data" , "the_text_you_want_to_save");
var xhr = (window.XMLHttpRequest) ? new XMLHttpRequest() : new activeXObject("Microsoft.XMLHTTP");
xhr.open( 'post', '/path/to/php', true );
xhr.send(data);
PHP:
if(!empty($_POST['data'])){
$data = $_POST['data'];
$fname = mktime() . ".txt";//generates random name
$file = fopen("upload/" .$fname, 'w');//creates new file
fwrite($file, $data);
fclose($file);
}
Edit:
As Florian mentioned below, the XHR fallback is not required since FormData
is not supported in older browsers (formdata browser compatibiltiy), so you can declare XHR variable as:
var xhr = new XMLHttpRequest();
Also please note that this works only for browsers that support FormData
such as IE +10.
Guid guidId = Guid.Parse("xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx");
string guidValue = guidId.ToString("D"); //return with hyphens
I compile Kotlin to byte code and then de-compile that to Java. I compile with the Kotlin compiler and de-compile with cfr.
My project is here.
This allows me to compile this:
package functionsiiiandiiilambdas.functions.p01tailiiirecursive
tailrec fun findFixPoint(x: Double = 1.0): Double =
if (x == Math.cos(x)) x else findFixPoint(Math.cos(x))
To this:
package functionsiiiandiiilambdas.functions.p01tailiiirecursive;
public final class ExampleKt {
public static final double findFixPoint(double x) {
while (x != Math.cos(x)) {
x = Math.cos(x);
}
return x;
}
public static /* bridge */ /* synthetic */ double findFixPoint$default(
double d, int n, Object object) {
if ((n & 1) != 0) {
d = 1.0;
}
return ExampleKt.findFixPoint(d);
}
}
Use this
@Cacheable(value="bookCache", key="#isbn + '_' + #checkWarehouse + '_' + #includeUsed")

How about another, simpler approach:
require 'fileutils'
FileUtils.cmp(file1, file2)
Object initializers are cool because they allow you to set up a class inline. The tradeoff is that your class cannot be immutable. Consider:
public class Album
{
// Note that we make the setter 'private'
public string Name { get; private set; }
public string Artist { get; private set; }
public int Year { get; private set; }
public Album(string name, string artist, int year)
{
this.Name = name;
this.Artist = artist;
this.Year = year;
}
}
If the class is defined this way, it means that there isn't really an easy way to modify the contents of the class after it has been constructed. Immutability has benefits. When something is immutable, it is MUCH easier to determine that it's correct. After all, if it can't be modified after construction, then there is no way for it to ever be 'wrong' (once you've determined that it's structure is correct). When you create anonymous classes, such as:
new {
Name = "Some Name",
Artist = "Some Artist",
Year = 1994
};
the compiler will automatically create an immutable class (that is, anonymous classes cannot be modified after construction), because immutability is just that useful. Most C++/Java style guides often encourage making members const
(C++) or final
(Java) for just this reason. Bigger applications are just much easier to verify when there are fewer moving parts.
That all being said, there are situations when you want to be able quickly modify the structure of your class. Let's say I have a tool that I want to set up:
public void Configure(ConfigurationSetup setup);
and I have a class that has a number of members such as:
class ConfigurationSetup {
public String Name { get; set; }
public String Location { get; set; }
public Int32 Size { get; set; }
public DateTime Time { get; set; }
// ... and some other configuration stuff...
}
Using object initializer syntax is useful when I want to configure some combination of properties, but not neccesarily all of them at once. For example if I just want to configure the Name
and Location
, I can just do:
ConfigurationSetup setup = new ConfigurationSetup {
Name = "Some Name",
Location = "San Jose"
};
and this allows me to set up some combination without having to define a new constructor for every possibly permutation.
On the whole, I would argue that making your classes immutable will save you a great deal of development time in the long run, but having object initializer syntax makes setting up certain configuration permutations much easier.
parseInt()
is just going to throw an exception if the parsing can't complete successfully. You can instead use Integers
, the corresponding object type, which makes things a little bit cleaner. So you probably want something closer to:
Integer s = null;
try {
s = Integer.valueOf(startField.getText());
}
catch (NumberFormatException e) {
// ...
}
if (s != null) { ... }
Beware if you do decide to use parseInt()
! parseInt()
doesn't support good internationalization, so you have to jump through even more hoops:
try {
NumberFormat nf = NumberFormat.getIntegerInstance(locale);
nf.setParseIntegerOnly(true);
nf.setMaximumIntegerDigits(9); // Or whatever you'd like to max out at.
// Start parsing from the beginning.
ParsePosition p = new ParsePosition(0);
int val = format.parse(str, p).intValue();
if (p.getIndex() != str.length()) {
// There's some stuff after all the digits are done being processed.
}
// Work with the processed value here.
} catch (java.text.ParseFormatException exc) {
// Something blew up in the parsing.
}

I was inspired by Steve's answer but thought I'd add a bit of flare to it. I like to do the work up front of writing extension methods so later I have less work to do calling the method.
For example with the modified version of Steve's answer below, instead of making this call...
MyUtilities.RunCommandCom("DIR", "/W", true)
I can actually just type out the command and call it from my strings like this...
Directly in code.
Call "CD %APPDATA% & TREE".RunCMD()
OR
From a variable.
Dim MyCommand = "CD %APPDATA% & TREE"
MyCommand.RunCMD()
OR
From a textbox.
textbox.text.RunCMD(WaitForProcessComplete:=True)
Extension methods will need to be placed in a Public Module and carry the <Extension>
attribute over the sub. You will also want to add Imports System.Runtime.CompilerServices
to the top of your code file.
There's plenty of info on SO about Extension Methods if you need further help.

My Android Studio version 3.6.1
After getting updated the latest version I have been facing this problem for few hours. My steps to solve this:
-> Updated sdk platform-tools [though it's not fetching my device yet]
-> Change the USB cable, then my 2 devices both are getting connected with Studio and run my app successfully.
I don't know this silly step might help anyone but U can have a look on that. I just share my experience, Thanks.
You could also use promises in this way:
some_3secs_function(this.some_value).then(function(){
some_5secs_function(this.some_other_value).then(function(){
some_8secs_function(this.some_other_other_value);
});
});
You would have to make some_value
global in order to access it from inside the .then
Alternatively, from the outer function you could return the value the inner function would use, like so:
one(some_value).then(function(return_of_one){
two(return_of_one).then(function(return_of_two){
three(return_of_two);
});
});
Since async/await is widely available now, this is the way to accomplish the same:
async function run(){
await $('#art1').animate({'width':'1000px'},1000,'linear').promise()
await $('#art2').animate({'width':'1000px'},1000,'linear').promise()
await $('#art3').animate({'width':'1000px'},1000,'linear').promise()
}
Which is basically "promisifying" your functions (if they're not already asynchronous), and then awaiting them
The other methods described assume a binary mask. If you want to use a real-valued single-channel grayscale image as a mask (e.g. from an alpha channel), you can expand it to three channels and then use it for interpolation:
assert len(mask.shape) == 2 and issubclass(mask.dtype.type, np.floating)
assert len(foreground_rgb.shape) == 3
assert len(background_rgb.shape) == 3
alpha3 = np.stack([mask]*3, axis=2)
blended = alpha3 * foreground_rgb + (1. - alpha3) * background_rgb
Note that mask
needs to be in range 0..1
for the operation to succeed. It is also assumed that 1.0
encodes keeping the foreground only, while 0.0
means keeping only the background.
If the mask may have the shape (h, w, 1)
, this helps:
alpha3 = np.squeeze(np.stack([np.atleast_3d(mask)]*3, axis=2))
Here np.atleast_3d(mask)
makes the mask (h, w, 1)
if it is (h, w)
and np.squeeze(...)
reshapes the result from (h, w, 3, 1)
to (h, w, 3)
.
That's invalid Javascript syntax; a property name cannot have a -
.
Use either zIndex
or "z-index"
.
Question is a little vague.
list_of_lines = multiple_lines.split("\n")
for line in list_of_lines:
list_of_items_in_line = line.split(",")
first_int = int(list_of_items_in_line[0])
etc.
I found interest answer for compare performance String vs StringBuffer by Reggie Hutcherso Source: http://www.javaworld.com/javaworld/jw-03-2000/jw-0324-javaperf.html
Java provides the StringBuffer and String classes, and the String class is used to manipulate character strings that cannot be changed. Simply stated, objects of type String are read only and immutable. The StringBuffer class is used to represent characters that can be modified.
The significant performance difference between these two classes is that StringBuffer is faster than String when performing simple concatenations. In String manipulation code, character strings are routinely concatenated. Using the String class, concatenations are typically performed as follows:
String str = new String ("Stanford ");
str += "Lost!!";
If you were to use StringBuffer to perform the same concatenation, you would need code that looks like this:
StringBuffer str = new StringBuffer ("Stanford ");
str.append("Lost!!");
Developers usually assume that the first example above is more efficient because they think that the second example, which uses the append method for concatenation, is more costly than the first example, which uses the + operator to concatenate two String objects.
The + operator appears innocent, but the code generated produces some surprises. Using a StringBuffer for concatenation can in fact produce code that is significantly faster than using a String. To discover why this is the case, we must examine the generated bytecode from our two examples. The bytecode for the example using String looks like this:
0 new #7 <Class java.lang.String>
3 dup
4 ldc #2 <String "Stanford ">
6 invokespecial #12 <Method java.lang.String(java.lang.String)>
9 astore_1
10 new #8 <Class java.lang.StringBuffer>
13 dup
14 aload_1
15 invokestatic #23 <Method java.lang.String valueOf(java.lang.Object)>
18 invokespecial #13 <Method java.lang.StringBuffer(java.lang.String)>
21 ldc #1 <String "Lost!!">
23 invokevirtual #15 <Method java.lang.StringBuffer append(java.lang.String)>
26 invokevirtual #22 <Method java.lang.String toString()>
29 astore_1
The bytecode at locations 0 through 9 is executed for the first line of code, namely:
String str = new String("Stanford ");
Then, the bytecode at location 10 through 29 is executed for the concatenation:
str += "Lost!!";
Things get interesting here. The bytecode generated for the concatenation creates a StringBuffer object, then invokes its append method: the temporary StringBuffer object is created at location 10, and its append method is called at location 23. Because the String class is immutable, a StringBuffer must be used for concatenation.
After the concatenation is performed on the StringBuffer object, it must be converted back into a String. This is done with the call to the toString method at location 26. This method creates a new String object from the temporary StringBuffer object. The creation of this temporary StringBuffer object and its subsequent conversion back into a String object are very expensive.
In summary, the two lines of code above result in the creation of three objects:
Now, let's look at the bytecode generated for the example using StringBuffer:
0 new #8 <Class java.lang.StringBuffer>
3 dup
4 ldc #2 <String "Stanford ">
6 invokespecial #13 <Method java.lang.StringBuffer(java.lang.String)>
9 astore_1
10 aload_1
11 ldc #1 <String "Lost!!">
13 invokevirtual #15 <Method java.lang.StringBuffer append(java.lang.String)>
16 pop
The bytecode at locations 0 to 9 is executed for the first line of code:
StringBuffer str = new StringBuffer("Stanford ");
The bytecode at location 10 to 16 is then executed for the concatenation:
str.append("Lost!!");
Notice that, as is the case in the first example, this code invokes the append method of a StringBuffer object. Unlike the first example, however, there is no need to create a temporary StringBuffer and then convert it into a String object. This code creates only one object, the StringBuffer, at location 0.
In conclusion, StringBuffer concatenation is significantly faster than String concatenation. Obviously, StringBuffers should be used in this type of operation when possible. If the functionality of the String class is desired, consider using a StringBuffer for concatenation and then performing one conversion to String.

I have come across exactly the same problem when trying to write a client for the National Rail SOAP service with Perl.
The problem was caused because the Perl module that I'm using 'SOAP::Lite' inserts a '#' in the SOAPAction header ...
SOAPAction: "http://thalesgroup.com/RTTI/2008-02-20/ldb/#GetDepartureBoard"
This is not interpreted correctly by .NET servers. I found this out from Example 3-19 in O'Reilly's Programming Web Services with SOAP . The solution was given below in section 3-20, namely you need to explicitly specify the format of the header with the 'on_action' method.
print SOAP::Lite
-> uri('urn:Example1')
-> on_action(sub{sprintf '%s/%s', @_ })
-> proxy('http://localhost:8080/helloworld/example1.asmx')
-> sayHello($name)
-> result . "\n\n";
My guess is that soapclient.com is using SOAP::Lite behind the scenes and so are hitting the same problem when talking to National Rail.
The solution is to write your own client so that you have control over the format of the SOAPAction header ... but you've probably done that already.
If you want to do remote debugging (for CGI or if you don't want to mess output with debug command line), use this:
Given test:
use v5.14;
say 1;
say 2;
say 3;
Start a listener on whatever host and port on terminal 1 (here localhost:12345
):
$ nc -v -l localhost -p 12345
For readline support use rlwrap (you can use on perl -d
too):
$ rlwrap nc -v -l localhost -p 12345
And start the test on another terminal (say terminal 2):
$ PERLDB_OPTS="RemotePort=localhost:12345" perl -d test
Input/Output on terminal 1:
Connection from 127.0.0.1:42994

select $DB::OUT
If you are Vim user, install this plugin: dbg.vim which provides basic support for Perl.
Sql Server 2012 has a function that will create the date based on the parts (DATEFROMPARTS). For the rest of us, here is a db function I created that will determine the date from the parts (thanks @Charles)...
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id(N'[dbo].[func_DateFromParts]'))
DROP FUNCTION [dbo].[func_DateFromParts]
GO
CREATE FUNCTION [dbo].[func_DateFromParts]
(
@Year INT,
@Month INT,
@DayOfMonth INT,
@Hour INT = 0, -- based on 24 hour clock (add 12 for PM :)
@Min INT = 0,
@Sec INT = 0
)
RETURNS DATETIME
AS
BEGIN
RETURN DATEADD(second, @Sec,
DATEADD(minute, @Min,
DATEADD(hour, @Hour,
DATEADD(day, @DayOfMonth - 1,
DATEADD(month, @Month - 1,
DATEADD(Year, @Year-1900, 0))))))
END
GO
You can call it like this...
SELECT dbo.func_DateFromParts(2013, 10, 4, 15, 50, DEFAULT)
Returns...

What I do on my cloud instances is I redirect port 80 to port 3000 with this command:
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3000
Then I launch my Node.js on port 3000. Requests to port 80 will get mapped to port 3000.
You should also edit your /etc/rc.local
file and add that line minus the sudo
. That will add the redirect when the machine boots up. You don't need sudo
in /etc/rc.local
because the commands there are run as root
when the system boots.
Use the forever module to launch your Node.js with. It will make sure that it restarts if it ever crashes and it will redirect console logs to a file.
Add your Node.js start script to the file you edited for port redirection, /etc/rc.local
. That will run your Node.js launch script when the system starts.
This not only applies to Linode, but Digital Ocean, AWS EC2 and other VPS providers as well. However, on RedHat based systems /etc/rc.local
is /ect/rc.d/local
.

An alternative way is to use MySql Workbench.

I have tried all suggestions and found my own simple solution.
The problem is that codes written in external environment like C
need compiler. Look for its own VS environment, i.e. VS 2008.
Currently my machine runs VS 2012 and faces Unable to find vcvarsall.bat
.
I studied codes that i want to install to find the VS version. It was VS 2008. i have add to system variable VS90COMNTOOLS
as variable name and gave the value of VS120COMNTOOLS
.
You can find my step by step solution below:
Now open a new session and pip install your-package
Yes, there are special server side comments:
<%-- Text not sent to client --%>
Checking if something isn't false... So it's true, just if you're doing something that is quantum physics.
if(!(borrar() === false))
or
if(borrar() === true)
I tried to added those files into my .gitignore
and it was useless...
Nevertheless, as Petr Syrov said, you can use git rm -r --cached .idea
into your terminal and those files won't be a problem anymore!
It also can be related with setting the adapter multiple times at the same time. I had a callback method which was triggered 5-6 times at the same time and I was setting the adapter in that callback so RecycledViewPool couldn't handle with all of those datas contemporaneously. It's a fat chance but you better check it out anyway.
Where do you want to see the output?
Messages being output via Debug.Print
will be displayed in the immediate window which you can open by pressing Ctrl+G.
You can also Activate the so called Immediate Window by clicking View -> Immediate Window on the VBE toolbar
in a very simple sentence: The significant difference being that Repositories represent collections, whilst DAOs are closer to the database, often being far more table-centric.
Check for already existing primary key with different column. If yes, drop the primary key using:
ALTER TABLE Table1
DROP CONSTRAINT PK_Table1_Col1
GO
and then write your query as it is.
On Mac OS X, for anyone having:
-bash: /usr/local/bin/composer: Permission denied
problem, while trying to move downloaded composer.phar
using:
mv composer.phar /usr/local/bin/composer
this is the cause:
System Integrity Protection
and this is the solution:
csrutil disable
and hit enter. You should see a msg returned saying that:
the System Integrity Protection is off.
/usr/bin
and NOT /usr/local/bin
because for some reason it just didn't work there.csrutil enable
The above 6 steps are copied from here, so all the credit belongs to the user Vasheer there.
Not knowing your code, it's a bit hard to answer your question, but based on all the info here, I believe the issue is you're trying to use Collections.sort passing in an object defined as Collection, and sort doesn't support that.
First question. Why is client defined so generically? Why isn't it a List, Map, Set or something a little more specific?
If client was defined as a List, Map or Set, you wouldn't have this issue, as then you'd be able to directly use Collections.sort(client).

Comparison of different approaches
Here is a quick comparison of some of the approaches I've tried with images showing what the give.
Baseline example without trying to set the image dimensions
Just to have a comparison point:
base.py
#!/usr/bin/env python3
import sys
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
fig, ax = plt.subplots()
print('fig.dpi = {}'.format(fig.dpi))
print('fig.get_size_inches() = ' + str(fig.get_size_inches())
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig('base.png', format='png')
run:
./base.py
identify base.png
outputs:
fig.dpi = 100.0
fig.get_size_inches() = [6.4 4.8]
base.png PNG 640x480 640x480+0+0 8-bit sRGB 13064B 0.000u 0:00.000
My best approach so far: plt.savefig(dpi=h/fig.get_size_inches()[1]
height-only control
I think this is what I'll go with most of the time, as it is simple and scales:
get_size.py
#!/usr/bin/env python3
import sys
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
height = int(sys.argv[1])
fig, ax = plt.subplots()
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig(
'get_size.png',
format='png',
dpi=height/fig.get_size_inches()[1]
)
run:
./get_size.py 431
outputs:
get_size.png PNG 574x431 574x431+0+0 8-bit sRGB 10058B 0.000u 0:00.000
and
./get_size.py 1293
outputs:
main.png PNG 1724x1293 1724x1293+0+0 8-bit sRGB 46709B 0.000u 0:00.000
I tend to set just the height because I'm usually most concerned about how much vertical space the image is going to take up in the middle of my text.
plt.savefig(bbox_inches='tight'
changes image size
I always feel that there is too much white space around images, and tended to add bbox_inches='tight'
from:
Removing white space around a saved image in matplotlib
However, that works by cropping the image, and you won't get the desired sizes with it.
Instead, this other approach proposed in the same question seems to work well:
plt.tight_layout(pad=1)
plt.savefig(...
which gives the exact desired height for height equals 431:
Fixed height, set_aspect
, automatically sized width and small margins
Ermmm, set_aspect
messes things up again and prevents plt.tight_layout
from actually removing the margins...
plt.savefig(dpi=h/fig.get_size_inches()[1]
+ width control
If you really need a specific width in addition to height, this seems to work OK:
width.py
#!/usr/bin/env python3
import sys
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
h = int(sys.argv[1])
w = int(sys.argv[2])
fig, ax = plt.subplots()
wi, hi = fig.get_size_inches()
fig.set_size_inches(hi*(w/h), hi)
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig(
'width.png',
format='png',
dpi=h/hi
)
run:
./width.py 431 869
output:
width.png PNG 869x431 869x431+0+0 8-bit sRGB 10965B 0.000u 0:00.000
and for a small width:
./width.py 431 869
output:
width.png PNG 211x431 211x431+0+0 8-bit sRGB 6949B 0.000u 0:00.000
So it does seem that fonts are scaling correctly, we just get some trouble for very small widths with labels getting cut off, e.g. the 100
on the top left.
I managed to work around those with Removing white space around a saved image in matplotlib
plt.tight_layout(pad=1)
which gives:
width.png PNG 211x431 211x431+0+0 8-bit sRGB 7134B 0.000u 0:00.000
From this, we also see that tight_layout
removes a lot of the empty space at the top of the image, so I just generally always use it.
Fixed magic base height, dpi
on fig.set_size_inches
and plt.savefig(dpi=
scaling
I believe that this is equivalent to the approach mentioned at: https://stackoverflow.com/a/13714720/895245
magic.py
#!/usr/bin/env python3
import sys
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
magic_height = 300
w = int(sys.argv[1])
h = int(sys.argv[2])
dpi = 80
fig, ax = plt.subplots(dpi=dpi)
fig.set_size_inches(magic_height*w/(h*dpi), magic_height/dpi)
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig(
'magic.png',
format='png',
dpi=h/magic_height*dpi,
)
run:
./magic.py 431 231
outputs:
magic.png PNG 431x231 431x231+0+0 8-bit sRGB 7923B 0.000u 0:00.000
And to see if it scales nicely:
./magic.py 1291 693
outputs:
magic.png PNG 1291x693 1291x693+0+0 8-bit sRGB 25013B 0.000u 0:00.000
So we see that this approach also does work well. The only problem I have with it is that you have to set that magic_height
parameter or equivalent.
Fixed DPI + set_size_inches
This approach gave a slightly wrong pixel size, and it makes it is hard to scale everything seamlessly.
set_size_inches.py
#!/usr/bin/env python3
import sys
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
w = int(sys.argv[1])
h = int(sys.argv[2])
fig, ax = plt.subplots()
fig.set_size_inches(w/fig.dpi, h/fig.dpi)
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(
0,
60.,
'Hello',
# Keep font size fixed independently of DPI.
# https://stackoverflow.com/questions/39395616/matplotlib-change-figsize-but-keep-fontsize-constant
fontdict=dict(size=10*h/fig.dpi),
)
plt.savefig(
'set_size_inches.png',
format='png',
)
run:
./set_size_inches.py 431 231
outputs:
set_size_inches.png PNG 430x231 430x231+0+0 8-bit sRGB 8078B 0.000u 0:00.000
so the height is slightly off, and the image:
The pixel sizes are also correct if I make it 3 times larger:
./set_size_inches.py 1291 693
outputs:
set_size_inches.png PNG 1291x693 1291x693+0+0 8-bit sRGB 19798B 0.000u 0:00.000
We understand from this however that for this approach to scale nicely, you need to make every DPI-dependant setting proportional to the size in inches.
In the previous example, we only made the "Hello" text proportional, and it did retain its height between 60 and 80 as we'd expect. But everything for which we didn't do that, looks tiny, including:
SVG
I could not find how to set it for SVG images, my approaches only worked for PNG e.g.:
get_size_svg.py
#!/usr/bin/env python3
import sys
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
height = int(sys.argv[1])
fig, ax = plt.subplots()
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig(
'get_size_svg.svg',
format='svg',
dpi=height/fig.get_size_inches()[1]
)
run:
./get_size_svg.py 431
and the generated output contains:
<svg height="345.6pt" version="1.1" viewBox="0 0 460.8 345.6" width="460.8pt"
and identify says:
get_size_svg.svg SVG 614x461 614x461+0+0 8-bit sRGB 17094B 0.000u 0:00.000
and if I open it in Chromium 86 the browser debug tools mouse image hover confirm that height as 460.79.
But of course, since SVG is a vector format, everything should in theory scale, so you can just convert to any fixed sized format without loss of resolution, e.g.:
inkscape -h 431 get_size_svg.svg -b FFF -e get_size_svg.png
gives the exact height:
TODO regenerate image, messed up the upload somehow.
I use Inkscape instead of Imagemagick's convert
here because you need to mess with -density
as well to get sharp SVG resizes with ImageMagick:
And setting <img height=""
on the HTML should also just work for the browser.
Tested on matplotlib==3.2.2.
You can use PdfBox from Apache which is simple to use and has good performance.
Here is an example of extracting text from a PDF file (you can read more here) :
import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;
public class PDFTest {
public static void main(String[] args){
PDDocument pd;
BufferedWriter wr;
try {
File input = new File("C:\\Invoice.pdf"); // The PDF file from where you would like to extract
File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
pd = PDDocument.load(input);
System.out.println(pd.getNumberOfPages());
System.out.println(pd.isEncrypted());
pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
PDFTextStripper stripper = new PDFTextStripper();
wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
stripper.writeText(pd, wr);
if (pd != null) {
pd.close();
}
// I use close() to flush the stream.
wr.close();
} catch (Exception e){
e.printStackTrace();
}
}
}
UPDATE:
You can get the text using PDFTextStripper:
PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created
You can also install R from this page:
https://cran.r-project.org/bin/macosx/
It works out of the box
buf.erase(buf.size() - 1);
This assumes you know that the string is not empty. If so, you'll get an out_of_range
exception.
Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import
to Tkinter
rather than tkinter
(the difference being the capitalization):
import tkinter as tk
#import Tkinter as tk # for python 2
def create_window():
window = tk.Toplevel(root)
root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()
root.mainloop()
This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.
Combination of keyup
and change
is not necessarily enough (browser's autocomplete and paste using mouse also changes the contents of a text box, but doesn't fire either of these events):
To track down the correct parameters you need to go first to ?plot.default
, which refers you to ?par
and ?axis
:
plot(1, 1 ,xlab="x axis", ylab="y axis", pch=19,
col.lab="red", cex.lab=1.5, # for the xlab and ylab
col="green") # for the points
If you are using Databinding on layout you can get the context
from holder
. An exemple below.
@Override
public void onBindViewHolder(@NonNull GenericViewHolder holder, int position) {
View currentView = holder.binding.getRoot().findViewById(R.id.cycle_count_manage_location_line_layout);// id of your root layout
currentView.setBackgroundColor(ContextCompat.getColor(holder.binding.getRoot().getContext(), R.color.light_green));
}
Does it matter which is faster, if they don't do the same thing? Comparing the performance of statements with different meaning seems like a bad idea.
is
tells you if the object implements ClassA
anywhere in its type heirarchy. GetType()
tells you about the most-derived type.
Not the same thing.

If you want to change background color, try this:
plt.rcParams['figure.facecolor'] = 'white'
You can do the same in python by simply importing the second file, code at the top level will run when imported. I'd suggest this is messy at best, and not a good programming practice. You would be better off organizing your code into modules
Example:
F1.py:
print "Hello, "
import f2
F2.py:
print "World!"
When run:
python ./f1.py
Hello,
World!
Edit to clarify: The part I was suggesting was "messy" is using the import
statement only for the side effect of generating output, not the creation of separate source files.
select to_timestamp(cast(epoch_ms/1000 as bigint))::date
worked for me
Some solutions work well for me but numpy will deprecate some parameters.
The solution that work better for me is to read the date as a pandas datetime and excract explicitly the year, month and day of a pandas object.
The following code works for the most common situation.
def format_dates(dates):
dt = pd.to_datetime(dates)
try: return [datetime.date(x.year, x.month, x.day) for x in dt]
except TypeError: return datetime.date(dt.year, dt.month, dt.day)
If your button was made with Interface Builder, and you're changing the title in code, you can do this:
[self.button setTitle:@"Button Title" forState:UIControlStateNormal];
[self.button sizeToFit];
It seems as of now, the only solution is still to install SublimeREPL.
To extend on Raghav's answer, it can be quite annoying to have to go into the Tools->SublimeREPL->Python->Run command every time you want to run a script with input, so I devised a quick key binding that may be handy:
To enable it, go to Preferences->Key Bindings - User, and copy this in there:
[
{"keys":["ctrl+r"] ,
"caption": "SublimeREPL: Python - RUN current file",
"command": "run_existing_window_command",
"args":
{
"id": "repl_python_run",
"file": "config/Python/Main.sublime-menu"
}
},
]
Naturally, you would just have to change the "keys" argument to change the shortcut to whatever you'd like.
You can add more than 1 element in one shot to array using array_push,
e.g. array_push($array_name, $element1, $element2,...)
Where $element1, $element2,... are elements to be added to array.
But if you want to add only one element at one time, then other method (i.e. using $array_name[]) should be preferred.
While @pritam kumar gives a good overview the 5th point is not true.

Reference
Both tools are meant to work with text and there are tasks both tools can be used for.
For me the rule to separate them is: Use sed
to automate tasks you would do otherwise in a text editor manually. That's why it is called stream editor. (You can use the same commands to edit text in vim). Use awk
if you want to analyze text, meaning counting fields, calculate totals, extract and reorganize structures etc.
Also you should not forget about grep
. Use grep
if you only want to search/extract something in a text (file)
You can use DDC (Domain Directory Controller). It is a new, easy to use, Java SDK. You don't even need to know LDAP to use it. It exposes an object-oriented API instead.
You can find it here.
You should execute the next query:
GRANT ALL ON TABLE mytable TO myuser;
Or if your error is in a view then maybe the table does not have permission, so you should execute the next query:
GRANT ALL ON TABLE tbm_grupo TO myuser;
I always add the following statement to a console application.(Create a code snippet for this if you wish)
Console.WriteLine("Press any key to quit!");
Console.ReadKey();
Doing this helps when you want to experiment different concepts through console application.
Ctr + F5 will make the Console stay but you cant debug! All the console applications that I have written in realworld is always non-interactive and triggered by a Scheduler such as TWS or CA Work station and did not require something like this.
Let's assume you have such history
---o---o---o---M---W---x-------x-------*
/
---A---B
Where A, B failed commits and W - is revert of M
So before I start fixing found problems I do cherry-pick of W commit to my branch
git cherry-pick -x W
Then I revert W commit on my branch
git revert W
After I can continue fixing.
The final history could look like:
---o---o---o---M---W---x-------x-------*
/ /
---A---B---W---W`----------C---D
When I send a PR it will clearly shows that PR is undo revert and adds some new commits.
A nice way to create buckets is the LOOKUP() function.
In this example contains cell A1 is a count of days. The vthe second parameter is a list of values. The third parameter is the list of bucket names.
=LOOKUP(A1,{0,7,14,31,90,180,360},{"0-6","7-13","14-30","31-89","90-179","180-359",">360"})
The DI thing actually is some kind of strategy pattern. Whenever you want to be some logic/implementation exchangeable you typically find an interface and an appropriate setter method on the host class to wire your custom implementation of that interface.
I met with this problem too. And I figured it out by the following way:
First, open the terminal and write
mongod --dbpath {your project's path}
Second, open a new terminal and enter your project's path, write
mongo
Then it runs successfully
I use this function :
<?php
function is_ping_address($ip) {
exec('ping -c1 -w1 '.$ip, $outcome, $status);
preg_match('/([0-9]+)% packet loss/', $outcome[3], $arr);
return ( $arr[1] == 100 ) ? false : true;
}
I like your server side idea, even if my proposed implementation of it sounds a little bit ghetto.
You could set the .innerHTML of the iframe to the HTML contents you grab server side. Depending on how you grab this, you will have to pay attention to relative versus absolute paths.
Plus, depending on how the page you are grabbing interacts with other pages, this could totally not work (cookies being set for the page you are grabbing won't work across domains, maybe state is being tracked in Javascript... Lots of reasons this might not work.)
I don't believe that tracking the current state of the page you are trying to mirror is theoretically possible, but I'm not sure. The site could track all sorts of things server side, you won't have access to this state. Imagine the case where on a page load a variable is set to a random value server-side, how would you capture this state?
Do these ideas help with anything?

For bootstrap 3.0, this worked for me:
.myclass .glyphicon {color:blue !important;}
Is this statement a thing of the past?
Yes. Don't use SELECT *
; it's a maintenance nightmare. There are tons of other threads on SO about why this construct is bad, and how avoiding it will help you write better queries.
See also:
Rather than depending on ArrayList.toString()
implementation, you could write a one-liner, if you are using java 8:
String result = sList.stream()
.reduce("", String::concat);
If you prefer using StringBuffer
instead of String since String::concat
has a runtime of O(n^2)
, you could convert every String
to StringBuffer
first.
StringBuffer result = sList.stream()
.map(StringBuffer::new)
.reduce(new StringBuffer(""), StringBuffer::append);
format = '%Y-%m-%d %H:%M %p'
The format is using %H
instead of %I
. Since %H
is the "24-hour" format, it's likely just discarding the %p
information. It works just fine if you change the %H
to %I
.
PySpark provides various filtering options based on arithmetic, logical and other conditions. Presence of NULL values can hamper further processes. Removing them or statistically imputing them could be a choice.
Below set of code can be considered:
# Dataset is df
# Column name is dt_mvmt
# Before filtering make sure you have the right count of the dataset
df.count() # Some number
# Filter here
df = df.filter(df.dt_mvmt.isNotNull())
# Check the count to ensure there are NULL values present (This is important when dealing with large dataset)
df.count() # Count should be reduced if NULL values are present
A quick way to do the thing now (previous ones haven't worked for me):
sudo wget https://github.com/mikefarah/yq/releases/download/v4.4.1/yq_linux_amd64 -O /usr/bin/yq &&\

If you've completed your other projects, why not take the time to learn Objective-C? There is a ton of material out on the web to help you get started. Honestly, it won't be that hard and learning to do some memory management will be a great learning exercise. Have you programmed in C before?
Most cross compilers won't do a great job in converting your code, and debugging your project may become much more difficult if you develop them this way.
You can also use the ToLookup
LINQ function, which you then can use almost interchangeably with a Dictionary.
_people = personList
.ToLookup(e => e.FirstandLastName, StringComparer.OrdinalIgnoreCase);
_people.ToDictionary(kl => kl.Key, kl => kl.First()); // Potentially unnecessary
This will essentially do the GroupBy in LukeH's answer, but will give the hashing that a Dictionary provides. So, you probably don't need to convert it to a Dictionary, but just use the LINQ First
function whenever you need to access the value for the key.

The DMG files linked on that page are ~270M and much quicker to install. This was perfect for me, getting homebrew up and running with a minimum of hassle.
The github project itself is basically a script that repackages just the critical chunks of xCode for distribution. In order to run that script and build the DMG files, you'd need to already have an XCode install, which would kind of defeat the point, so the pre-built DMG files are hosted on the project page.
How about: if(($counter % $display) == 0)
Why do not use array_diff?
$array = array(
1 => 'Awaiting for Confirmation',
2 => 'Asssigned',
3 => 'In Progress',
4 => 'Completed',
5 => 'Mark As Spam',
);
$to_delete = array('Completed', 'Mark As Spam');
$array = array_diff($array, $to_delete);
Just note that your array would be reindexed.
To convert tuples to list
(Commas were missing between the tuples in the given question, it was added to prevent error message)
Method 1:
level1 = (
(1,1,1,1,1,1),
(1,0,0,0,0,1),
(1,0,0,0,0,1),
(1,0,0,0,0,1),
(1,0,0,0,0,1),
(1,1,1,1,1,1))
level1 = [list(row) for row in level1]
print(level1)
Method 2:
level1 = map(list,level1)
print(list(level1))
