//Delete all records of table
db.execSQL("DELETE FROM " + TABLE_NAME);

//Reset the auto_increment primary key if you needed
db.execSQL("UPDATE SQLITE_SEQUENCE SET SEQ=0 WHERE NAME=" + TABLE_NAME);

//For go back free space by shrinking sqlite file
db.execSQL("VACUUM");

Use the left function:

QString yourString = "This is a string";
QString leftSide = yourString.left(5);
qDebug() << leftSide; // output "This "

Also have a look at mid() if you want more control.

Dead easy solution, ws and port, tested:

var ws = new WebSocket("ws://" + window.location.host + ":6666");

ws.onopen = function() { ws.send( .. etc

I'm going to expand your question a bit and also include the compile function.

• compile function - use for template DOM manipulation (i.e., manipulation of tElement = template element), hence manipulations that apply to all DOM clones of the template associated with the directive. (If you also need a link function (or pre and post link functions), and you defined a compile function, the compile function must return the link function(s) because the 'link' attribute is ignored if the 'compile' attribute is defined.)

• link function - normally use for registering listener callbacks (i.e., $watch expressions on the scope) as well as updating the DOM (i.e., manipulation of iElement = individual instance element). It is executed after the template has been cloned. E.g., inside an <li ng-repeat...>, the link function is executed after the <li> template (tElement) has been cloned (into an iElement) for that particular <li> element. A $watch allows a directive to be notified of scope property changes (a scope is associated with each instance), which allows the directive to render an updated instance value to the DOM.

• controller function - must be used when another directive needs to interact with this directive. E.g., on the AngularJS home page, the pane directive needs to add itself to the scope maintained by the tabs directive, hence the tabs directive needs to define a controller method (think API) that the pane directive can access/call.
  
  For a more in-depth explanation of the tabs and pane directives, and why the tabs directive creates a function on its controller using this (rather than on $scope), please see 'this' vs $scope in AngularJS controllers.

In general, you can put methods, $watches, etc. into either the directive's controller or link function. The controller will run first, which sometimes matters (see this fiddle which logs when the ctrl and link functions run with two nested directives). As Josh mentioned in a comment, you may want to put scope-manipulation functions inside a controller just for consistency with the rest of the framework.

For checking existence one can also use (works for both, files and folders):

Not Dir(DirFile, vbDirectory) = vbNullString

_{The result is True if a file or a directory exists.}

Example:

If Not Dir("C:\Temp\test.xlsx", vbDirectory) = vbNullString Then
    MsgBox "exists"
Else
    MsgBox "does not exist"
End If

you can use the DBMS_SQL.DESCRIBE_COLUMNS2

    SET SERVEROUTPUT ON;
DECLARE
    STMT CLOB;
    CUR NUMBER;
    COLCNT NUMBER;
    IDX NUMBER;
    COLDESC DBMS_SQL.DESC_TAB2;
BEGIN
    CUR := DBMS_SQL.OPEN_CURSOR;
    STMT := 'SELECT  object_name , to_char(object_id), created FROM    DBA_OBJECTS where rownum<10';

    SYS.DBMS_SQL.PARSE(CUR, STMT, DBMS_SQL.NATIVE);
    DBMS_SQL.DESCRIBE_COLUMNS2(CUR, COLCNT, COLDESC);
    DBMS_OUTPUT.PUT_LINE('Statement: ' || STMT);
    FOR IDX IN 1 .. COLCNT
    LOOP
        CASE COLDESC(IDX).col_type
        WHEN 2 THEN
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': NUMBER');
        WHEN 12 THEN
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': DATE');
        WHEN 180 THEN
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': TIMESTAMP');

        -- Insert more cases if you need them
        ELSE
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': OTHERS (' || TO_CHAR(COLDESC(IDX).col_type) || ')');
        END CASE;

This stored procedure inserts a rand number into a table. Look out, it inserts an endless numbers. Stop executing it when u get enough numbers.

create a table for the cursor:

CREATE TABLE [dbo].[SearchIndex](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Cursor] [nvarchar](255) NULL) 

GO

Create a table to contain your numbers:

CREATE TABLE [dbo].[ID](
[IDN] [int] IDENTITY(1,1) NOT NULL,
[ID] [int] NULL)

INSERTING THE SCRIPT :

INSERT INTO [SearchIndex]([Cursor])  SELECT N'INSERT INTO ID  SELECT   FLOOR(rand() * 9 + 1)  SELECT COUNT (ID) FROM ID

CREATING AND EXECUTING THE PROCEDURE:

CREATE PROCEDURE [dbo].[RandNumbers] AS
BEGIN
Declare  CURSE  CURSOR  FOR (SELECT  [Cursor] FROM [dbo].[SearchIndex]  WHERE [Cursor] IS NOT NULL)
DECLARE @RandNoSscript NVARCHAR (250)
OPEN CURSE
FETCH NEXT FROM CURSE
INTO @RandNoSscript 
WHILE @@FETCH_STATUS IS NOT NULL 
BEGIN
Print @RandNoSscript
EXEC SP_EXECUTESQL @RandNoSscript;  
 END
 END
GO

Fill your table:

EXEC RandNumbers

you need to put a dot between the class like

class="column.wrapper">

Within the environment align from the package amsmath it is possible to combine the use of \label and \tag for each equation or line. For example, the code:

\documentclass{article}
\usepackage{amsmath}

\begin{document}
Write
\begin{align}
x+y\label{eq:eq1}\tag{Aa}\\
x+z\label{eq:eq2}\tag{Bb}\\
y-z\label{eq:eq3}\tag{Cc}\\
y-2z\nonumber
\end{align}
then cite \eqref{eq:eq1} and \eqref{eq:eq2} or \eqref{eq:eq3} separately.
\end{document}

produces:

The easiest way to add utility functions is to leave them at the global level:

function myUtilityFunction(x) { return "do something with "+x; }

Then, the simplest way to add a utility function (to a controller) is to assign it to $scope, like this:

$scope.doSomething = myUtilityFunction;

Then you can call it like this:

{{ doSomething(x) }}

or like this:

ng-click="doSomething(x)"

EDIT:

The original question is if the best way to add a utility function is through a service. I say no, if the function is simple enough (like the isNotString() example provided by the OP).

The benefit of writing a service is to replace it with another (via injection) for the purpose of testing. Taken to an extreme, do you need to inject every single utility function into your controller?

The documentation says to simply define behavior in the controller (like $scope.double): http://docs.angularjs.org/guide/controller

you'd use another join, something along these lines:

SELECT toD.dom_url AS ToURL, 
    fromD.dom_url AS FromUrl, 
    rvw.*

FROM reviews AS rvw

LEFT JOIN domain AS toD 
    ON toD.Dom_ID = rvw.rev_dom_for

LEFT JOIN domain AS fromD 
    ON fromD.Dom_ID = rvw.rev_dom_from

EDIT:

All you're doing is joining in the table multiple times. Look at the query in the post: it selects the values from the Reviews tables (aliased as rvw), that table provides you 2 references to the Domain table (a FOR and a FROM).

At this point it's a simple matter to left join the Domain table to the Reviews table. Once (aliased as toD) for the FOR, and a second time (aliased as fromD) for the FROM.

Then in the SELECT list, you will select the DOM_URL fields from both LEFT JOINS of the DOMAIN table, referencing them by the table alias for each joined in reference to the Domains table, and alias them as the ToURL and FromUrl.

For more info about aliasing in SQL, read here.

You can use the free foxit reader to fill in the forms, and if you pay a little you can design the forms that way you want.

You can also us iText to programmaticly create those forms.

There are free online services that allow you to upload a pdf and you can add fields also.

It depends on how you want to do the designing.

EDIT: If you use foxit reader, you can save any form that is fillable.

I was getting this error due to the BasicHttpBinding not sending a compatible messageVersion to the service i was calling. My solution was to use a custom binding like below

      <security authenticationMode="UserNameOverTransport">

If it's XHTML, your example is, you need only simpleXML.

<?php
$input = '<img src="/image/fluffybunny.jpg" title="Harvey the bunny" alt="a cute little fluffy bunny"/>';
$sx = simplexml_load_string($input);
var_dump($sx);
?>

Output:

object(SimpleXMLElement)#1 (1) {
  ["@attributes"]=>
  array(3) {
    ["src"]=>
    string(22) "/image/fluffybunny.jpg"
    ["title"]=>
    string(16) "Harvey the bunny"
    ["alt"]=>
    string(26) "a cute little fluffy bunny"
  }
}

Personally I would suggest this is an error as opposed to a setting that needs adjusting. In my code it was because I had a class that had the same name as a library within one of my controllers and it seemed to trip it up.

Output errors and see where this is being triggered.

The issue is not with the version of node. Instead, it is the way NodeJS is installed by default in Ubuntu. When running a Node application in Ubuntu you have to run nodejs somethign.js instead of node something.js

So the application name called in the terminal is nodejs and not node. This is why there is a need for a symlink to simply forward all the commands received as node to nodejs.

sudo ln -s /usr/bin/nodejs /usr/bin/node

Check if you have installed psycopg2 if not

sudo apt-get install psycopg2

Install the dependencies.

sudo apt-get build-dep python-psycopg2

These two commands should solve the problem.

You can use "export default" by calling an Arrow Function that returns its React.Component by passing it through the MaterialUI class object props, which in turn will be used within the Component render ().

class AllowanceClass extends Component{
    ...
    render() {
        const classes = this.props.classes;
        ...
    }
}

export default () => {
    const classes = useStyles();
    return (
        <AllowanceClass classes={classes} />
    )
}

try this:

create procedure dept_count( @dept_name varchar(20), @d_count INTEGER out)

   AS
   begin
     select count(*) into d_count
     from instructor
     where instructor.dept_name=dept_count.dept_name
   end

If you use the jQuery solution it will work on IE8:

jQuery

$(document).ready(function(){
$('#myList li:nth-child(odd)').addClass('alternate');
});

CSS

.alternate {
background: black;
}

If you use the CSS soloution it won't work on IE8:

li:nth-child(odd) {
    background: black;
}

Instead of wading through the description of all the options, you can jump to 3.4.3 Short Options Cross Reference under the info tar command.

x means --extract. v means --verbose. f means --file. z means --gzip. You can combine one-letter arguments together, and f takes an argument, the filename. There is something you have to watch out for:

Short options' letters may be clumped together, but you are not required to do this (as compared to old options; see below). When short options are clumped as a set, use one (single) dash for them all, e.g., ''tar' -cvf'. Only the last option in such a set is allowed to have an argument(1).

---

This old way of writing 'tar' options can surprise even experienced users. For example, the two commands:

 tar cfz archive.tar.gz file
 tar -cfz archive.tar.gz file

are quite different. The first example uses 'archive.tar.gz' as the value for option 'f' and recognizes the option 'z'. The second example, however, uses 'z' as the value for option 'f' -- probably not what was intended.

You'll need some math here:

Suppose A = (Xa, Ya), B = (Xb, Yb) and C = (Xc, Yc). Any point on the line from A to B has coordinates (alpha*Xa + (1-alpha)Xb, alphaYa + (1-alpha)*Yb) = P

If the point P has distance R to C, it must be on the circle. What you want is to solve

distance(P, C) = R

that is

(alpha*Xa + (1-alpha)*Xb)^2 + (alpha*Ya + (1-alpha)*Yb)^2 = R^2
alpha^2*Xa^2 + alpha^2*Xb^2 - 2*alpha*Xb^2 + Xb^2 + alpha^2*Ya^2 + alpha^2*Yb^2 - 2*alpha*Yb^2 + Yb^2=R^2
(Xa^2 + Xb^2 + Ya^2 + Yb^2)*alpha^2 - 2*(Xb^2 + Yb^2)*alpha + (Xb^2 + Yb^2 - R^2) = 0

if you apply the ABC-formula to this equation to solve it for alpha, and compute the coordinates of P using the solution(s) for alpha, you get the intersection points, if any exist.

Using Java 7 to read files with NIO.2

Import these packages:

import java.nio.charset.Charset;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

This is the process to read a file:

Path file = Paths.get("C:\\Java\\file.txt");

if(Files.exists(file) && Files.isReadable(file)) {

    try {
        // File reader
        BufferedReader reader = Files.newBufferedReader(file, Charset.defaultCharset());

        String line;
        // read each line
        while((line = reader.readLine()) != null) {
            System.out.println(line);
            // tokenize each number
            StringTokenizer tokenizer = new StringTokenizer(line, " ");
            while (tokenizer.hasMoreElements()) {
                // parse each integer in file
                int element = Integer.parseInt(tokenizer.nextToken());
            }
        }
        reader.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

To read all lines of a file at once:

Path file = Paths.get("C:\\Java\\file.txt");
List<String> lines = Files.readAllLines(file, StandardCharsets.UTF_8);

Arkaitz is correct that string is a managed type. What this means for you is that you never have to worry about how long the string is, nor do you have to worry about freeing or reallocating the memory of the string.

On the other hand, the char[] notation in the case above has restricted the character buffer to exactly 256 characters. If you tried to write more than 256 characters into that buffer, at best you will overwrite other memory that your program "owns". At worst, you will try to overwrite memory that you do not own, and your OS will kill your program on the spot.

Bottom line? Strings are a lot more programmer friendly, char[]s are a lot more efficient for the computer.

I had this issue and found that the installation of the newer openssl did actually work, but my PATH was setup incorrectly for it -- my $PATH had the ports path placed before my brew path so it always found the older version of openssl.

The fix for me was to put the path to brew (/usr/local/bin) at the front of my $PATH.

To find out where you're loading openssl from, run which openssl and note the output. It will be the location of the version your system is using when you run openssl. Its going to be somewhere other than the brewpath of "/usr/local/bin". Change your $PATH, close that terminal tab and open a new one, and run which openssl. You should see a different path now, probably under /usr/local/bin. Now run openssl version and you should see the new version you installed "OpenSSL 1.0.1e 11 Feb 2013".

The biggest threat is that an attacker could leverage a vulnerability such as; directory traversal, or using SQL Injection to call load_file() to read the plain text username/password in the configuration file and then Login using phpmyadmin or over tcp port 3306. As a pentester I have used this attack pattern to compromise a system.

Here is a great way to lock down phpmyadmin:

• DO NOT ALLOW REMOTE ROOT LOGINS! Instead phpmyadmin can be configured to use "Cookie Auth" to limit what user can access the system. If you need some root privileges, create a custom account that can add/drop/create but doesn't have grant or file_priv.
• Remove file_priv permissions from every account. file_priv is one of the most dangerous privileges in MySQL because it allows an attacker to read files or upload a backdoor.
• Whitelist IP address who have access to the phpmyadmin interface. Here is an example .htaccess reulset:

Order deny,allow
Deny from all
allow from 199.166.210.1

• Do not have a predictable file location like: http://127.0.0.1/phpmyadmin. Vulnerability scanners like Nessus/Nikto/Acunetix/w3af will scan for this.

• Firewall off tcp port 3306 so that it cannot be accessed by an attacker.

• Use HTTPS, otherwise data and passwords can be leaked to an attacker. If you don't want to fork out the $30 for a cert, then use a self-signed. You'll accept it once, and even if it was changed due to a MITM you'll be notified.

Derivation of delete queries using given method name is supported starting with version 1.6.0.RC1 of Spring Data JPA. The keywords remove and delete are supported. As return value one can choose between the number or a list of removed entities.

Long removeByLastname(String lastname);

List<User> deleteByLastname(String lastname);

        if klass is None:
            klass = type(obj)
        return self.fget.__get__(obj, klass)()

    def __set__(self, obj, value):
        if not self.fset:
            raise AttributeError("can't set attribute")
        type_ = type(obj)
        return self.fset.__get__(obj, type_)(value)

    def setter(self, func):
        if not isinstance(func, (classmethod, staticmethod)):
            func = classmethod(func)
        self.fset = func
        return self

def classproperty(func):
    if not isinstance(func, (classmethod, staticmethod)):
        func = classmethod(func)

    return ClassPropertyDescriptor(func)


class Bar(object):

    _bar = 1

    @classproperty
    def bar(cls):
        return cls._bar

    @bar.setter
    def bar(cls, value):
        cls._bar = value


# test instance instantiation
foo = Bar()
assert foo.bar == 1

baz = Bar()
assert baz.bar == 1

# test static variable
baz.bar = 5
assert foo.bar == 5

# test setting variable on the class
Bar.bar = 50
assert baz.bar == 50
assert foo.bar == 50

The setter didn't work at the time we call Bar.bar, because we are calling TypeOfBar.bar.__set__, which is not Bar.bar.__set__.

Adding a metaclass definition solves this:

class ClassPropertyMetaClass(type):
    def __setattr__(self, key, value):
        if key in self.__dict__:
            obj = self.__dict__.get(key)
        if obj and type(obj) is ClassPropertyDescriptor:
            return obj.__set__(self, value)

        return super(ClassPropertyMetaClass, self).__setattr__(key, value)

# and update class define:
#     class Bar(object):
#        __metaclass__ = ClassPropertyMetaClass
#        _bar = 1

# and update ClassPropertyDescriptor.__set__
#    def __set__(self, obj, value):
#       if not self.fset:
#           raise AttributeError("can't set attribute")
#       if inspect.isclass(obj):
#           type_ = obj
#           obj = None
#       else:
#           type_ = type(obj)
#       return self.fset.__get__(obj, type_)(value)

Now all will be fine.

The second parameter is what makes it open in a new window. Don't forget to read Jakob Nielsen's informative article :)

Trying to solve the same problem (validation without getting into complex plugins and libraries), I created jQuery.serializeJSON, that improves serializeArray to support any kind of nested objects.

This plugin got very popular, but in another project I was using Backbone.js, where I would like to write the validation logic in the Backbone.js models. Then I created Backbone.Formwell, which allows you to show the errors returned by the validation method directly in the form.

I would like to provide an additional solution that improves the accepted answer. I have previously provided the answers in another thread here.

from flask import Flask
from flask.json import JSONEncoder

from bson import json_util

from . import resources

# define a custom encoder point to the json_util provided by pymongo (or its dependency bson)
class CustomJSONEncoder(JSONEncoder):
    def default(self, obj): return json_util.default(obj)

application = Flask(__name__)
application.json_encoder = CustomJSONEncoder

if __name__ == "__main__":
    application.run()

I did a stupid mistake. I forgot to mention the class as public or open while updating code in cocoapod workspace.

Please do check whether accesor if working in separate workspace.

You have multiple columns named the same thing in your inner query, so the error is raised in the outer query. If you get rid of the outer query, it should run, although still be confusing:

SELECT DISTINCT
    coaches.id,
    people.*,
    users.*,
    coaches.*
FROM "COACHES"
    INNER JOIN people ON people.id = coaches.person_id
    INNER JOIN users ON coaches.person_id = users.person_id
    LEFT OUTER JOIN organizations_users ON organizations_users.user_id = users.id
WHERE
    rownum <= 25

It would be much better (for readability and performance both) to specify exactly what fields you need from each of the tables instead of selecting them all anyways. Then if you really need two fields called the same thing from different tables, use column aliases to differentiate between them.

The best and most flexible way

My demo on dabblet.com

The main trick in this demo is that in the normal flow of elements going from top to bottom, so the margin-top: auto is set to zero. However, an absolutely positioned element acts the same for distribution of free space, and similarly can be centered vertically at the specified top and bottom (does not work in IE7).

This trick will work with any sizes of div.

div {_x000D_
 width: 100px;_x000D_
 height: 100px;_x000D_
 background-color: red;_x000D_
 _x000D_
 position: absolute;_x000D_
 top:0;_x000D_
 bottom: 0;_x000D_
 left: 0;_x000D_
 right: 0;_x000D_
   _x000D_
 margin: auto;_x000D_
}

<div></div>

Are you interested in counting the executable lines rather than the total file line count? If so you could try a code coverage tool such as EclEmma. As a side effect of the code coverage stats you get stats on the number of executable lines and blocks (and methods and classes). These are rolled up from the method level upwards, so you can see line counts for the packages, source roots and projects as well.

For windows users: if git config or set http_proxy= doesn't work, this answer may help:

replace the git:// protocol of the git repository with http://. Note, you'll have to set the http_proxy first, anyways.

For me all the things stated here https://stackoverflow.com/a/6395750/939501 were true but still it was throwing error, reason was I created a View class with name ABCView and then deleted it later I added a view controller as ABCViewController so somehow it was referring to old ABCView in new view controller, I had to delete the ABCViewController and add a new one with different name that solved my issue.

It's a prefix to indicate the number is in hexadecimal rather than in some other base. The C programming language uses it to tell compiler.

Example:

0x6400 translates to 6*16^3 + 4*16^2 + 0*16^1 +0*16^0 = 25600. When compiler reads 0x6400, It understands the number is hexadecimal with the help of 0x term. Usually we can understand by (6400)₁₆ or (6400)₈ or whatever ..

For binary it would be:

0b00000001

Hope I have helped in some way.

You can use the keyCode of the arrow keys (37, 38, 39 and 40 for left, up, right and down):

$('.selector').keydown(function (e) {
  var arrow = { left: 37, up: 38, right: 39, down: 40 };

  switch (e.which) {
    case arrow.left:
      //..
      break;
    case arrow.up:
      //..
      break;
    case arrow.right:
      //..
      break;
    case arrow.down:
      //..
      break;
  }
});

Check the above example here.

Comparision of Agile to Scrum is similar to comparision of organism to one organ.

Scrum suggests the way of management while it doesn't prescribe everything what is necessary to do to be able to react fast on changes. Only by adding other agile techniques like continuous integration, extreme programming, test driven development your teams will be able to deliver products not just fast, but also product that customer wants with great quality.

Generally, there is a practice in machine learning community not to learn something that you don’t want to. For example, consider a classification problem where one's goal is to assign y labels to a given x input. If we use generative model

p(x,y)=p(y|x).p(x)

we have to model p(x) which is irrelevant for the task in hand. Practical limitations like data sparseness will force us to model p(x) with some weak independence assumptions. Therefore, we intuitively use discriminative models for classification.

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

check your casing, the name is typically stored in upper case

SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;

Or you can use

<select [(ngModel)]="Answers[''+question.Name+'']" ng-options="option for option in question.Options">
        </select>

MATLAB's FOR loop is static in nature; you cannot modify the loop variable between iterations, unlike the for(initialization;condition;increment) loop structure in other languages. This means that the following code always prints 1, 2, 3, 4, 5 regardless of the value of B.

A = 1:5;

for i = A
    A = B;
    disp(i);
end

If you want to be able to respond to changes in the data structure during iterations, a WHILE loop may be more appropriate --- you'll be able to test the loop condition at every iteration, and set the value of the loop variable(s) as you wish:

n = 10;
f = n;
while n > 1
    n = n-1;
    f = f*n;
end
disp(['n! = ' num2str(f)])

Btw, the for-each loop in Java (and possibly other languages) produces unspecified behavior when the data structure is modified during iteration. If you need to modify the data structure, you should use an appropriate Iterator instance which allows the addition and removal of elements in the collection you are iterating. The good news is that MATLAB supports Java objects, so you can do something like this:

A = java.util.ArrayList();
A.add(1);
A.add(2);
A.add(3);
A.add(4);
A.add(5);

itr = A.listIterator();

while itr.hasNext()

    k = itr.next();
    disp(k);

    % modify data structure while iterating
    itr.remove();
    itr.add(k);

end

I ran into this error when I had a .jsx and .scss file in the same directory with the same root name.

So, for example, if you have Component.jsx and Component.scss in the same folder and you try to do this:

import Component from ./Component

Webpack apparently gets confused and, at least in my case, tries to import the scss file when I really want the .jsx file.

I was able to fix it by renaming the .scss file and avoiding the ambiguity. I could have also explicitly imported Component.jsx

The second part of your question is answered well. Here is the answer for the first part: How to output multiple files with webpack:

    entry: {
            outputone: './source/fileone.jsx',
            outputtwo: './source/filetwo.jsx'
            },
    output: {
            path: path.resolve(__dirname, './wwwroot/js/dist'),
            filename: '[name].js'      
            },

This will generate 2 files: outputone.js und outputtwo.js in the target folder.

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

I had the same issue and thought it can be simply solved by a cron job calling unattended-upgrade daily.

My intention is to have this as an automatic and quick solution to ensure that production container is secure and updated because it can take me sometime to update my images and deploy a new docker image with the latest security updates.

It is also possible to automate the image build and deployment with Github hooks

I've created a basic docker image with that automatically checks and installs security updates daily (can run directly by docker run itech/docker-unattended-upgrade ).

I also came across another different approach to check if the container needs an update.

My complete implementation:

Dockerfile

FROM ubuntu:14.04   

RUN apt-get update \
&& apt-get install -y supervisor unattended-upgrades \
&& rm -rf /var/lib/apt/lists/*

COPY install /install
RUN chmod 755 install
RUN /install

COPY start /start
RUN chmod 755 /start

Helper scripts

install

#!/bin/bash
set -e

cat > /etc/supervisor/conf.d/cron.conf <<EOF
[program:cron]
priority=20
directory=/tmp
command=/usr/sbin/cron -f
user=root
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/%(program_name)s.log
stderr_logfile=/var/log/supervisor/%(program_name)s.log
EOF

rm -rf /var/lib/apt/lists/*

ENTRYPOINT ["/start"]

start

#!/bin/bash

set -e

echo "Adding crontab for unattended-upgrade ..."
echo "0 0 * * * root /usr/bin/unattended-upgrade" >> /etc/crontab

# can also use @daily syntax or use /etc/cron.daily

echo "Starting supervisord ..."
exec /usr/bin/supervisord -n -c /etc/supervisor/supervisord.conf

Edit

I developed a small tool docker-run that runs as docker container and can be used to update packages inside all or selected running containers, it can also be used to run any arbitrary commands.

Can be easily tested with the following command:

docker run --rm -v /var/run/docker.sock:/tmp/docker.sock itech/docker-run exec

which by default will execute date command in all running containers and display the results. If you pass update instead of exec it will execute apt-get update followed by apt-get upgrade -y in all running containers

I've got a pretty simple yet smart workaround: Just define the array with variables in its name. For example:

for (( i=0 ; i<$(($maxvalue + 1)) ; i++ ))
  do
  for (( j=0 ; j<$(($maxargument + 1)) ; j++ ))
    do
    declare -a array$i[$j]=((Your rule))
  done
done

Don't know whether this helps since it's not exactly what you asked for, but it works for me. (The same could be achieved just with variables without the array)

Try this if you have only one Fragment

if (getSupportFragmentManager().getBackStackEntryCount() == 0) {
                    //TODO: Your Code Here
                }

You can achieve it by using following code,

@Query(value = "SELECT * FROM users u WHERE  ORDER BY ?#{#pageable}", nativeQuery = true)
List<User> getUsers(String name, Pageable pageable);

Simply use ORDER BY ?#{#pageable} and pass page request to your method.

Enjoy!

There are a wide varieties of solutions to this problem documented here, including this little gem:

CREATE FUNCTION dbo.Split (@sep char(1), @s varchar(512))
RETURNS table
AS
RETURN (
    WITH Pieces(pn, start, stop) AS (
      SELECT 1, 1, CHARINDEX(@sep, @s)
      UNION ALL
      SELECT pn + 1, stop + 1, CHARINDEX(@sep, @s, stop + 1)
      FROM Pieces
      WHERE stop > 0
    )
    SELECT pn,
      SUBSTRING(@s, start, CASE WHEN stop > 0 THEN stop-start ELSE 512 END) AS s
    FROM Pieces
  )

Well there are a few ways to go about this depending on the intended behavior, but this link should give you all the best solutions and not surprisingly is from Dianne Hackborn

http://groups.google.com/group/android-developers/browse_thread/thread/d2a5c203dad6ec42

Essentially you have the following options

• Use a name for your initial back stack state and use FragmentManager.popBackStack(String name, FragmentManager.POP_BACK_STACK_INCLUSIVE).
• Use FragmentManager.getBackStackEntryCount()/getBackStackEntryAt().getId() to retrieve the ID of the first entry on the back stack, and FragmentManager.popBackStack(int id, FragmentManager.POP_BACK_STACK_INCLUSIVE).
• FragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE) is supposed to pop the entire back stack... I think the documentation for that is just wrong. (Actually I guess it just doesn't cover the case where you pass in POP_BACK_STACK_INCLUSIVE),

For AVD with 5.1.1 and 6.0 I used next script in windows:

set adb=adb -s emulator-5558
set arch=x64
set pie=
adb start-server
%adb% root
%adb% remount
rem %adb% shell mount -o remount,rw /system
%adb% shell setenforce 0
%adb% install common/Superuser.apk
%adb% push %arch%/su%pie% /system/bin/su
%adb% shell chmod 0755 /system/bin/su
%adb% push %arch%/su%pie% /system/xbin/su
%adb% shell chmod 0755 /system/xbin/su
%adb% shell su --install
%adb% shell "su --daemon&"
rem %adb% shell mount -o remount,ro /system

exit /b

Need UPDATE.zip from SuperSU. Unpacked them to any folder. Create bat file with content above. Do not forget specify necessary architecture and device: set adb=adb -s emulator-5558 and set arch=x64. If you run Android above or equal 5.0, change set pie= to set pie=.pie. Run it. You get temporary root for current run.

If you got error on remount system partition then you need start AVD from command line. See below first step for Android 7.

If you want make it persistent - update binary in SuperSU and store system.img from temp folder as replace of default system.img.

How to convert the resulting temporary root on a permanent

First - it goes to SuperSu. It offers a binary upgrade. Update in the normal way. Reboot reject.

Second - only relevant for emulators. The same AVD. The bottom line is that changes in the system image will not be saved. You need to keep them for themselves.

There are already instructions vary for different emulators.

For AVD you can try to find a temporary file system.img, save it somewhere and use when you start the emulator.

In Windows it is located in the %LOCALAPPDATA%\Temp\AndroidEmulator and has a name something like TMP4980.tmp.

You copy it to a folder avd device (%HOMEPATH%\.android\avd\%AVD_NAME%.avd\), and renamed to the system.img.

Now it will be used at the start, instead of the usual. True if the image in the SDK is updated, it will have the old one.

In this case, you will need to remove this system.img, and repeat the operation on its creation.

More detailed manual in Russian: http://4pda.ru/forum/index.php?showtopic=318487&view=findpost&p=45421931

For android 7 you need run additional steps: 1. Need run emulator manually. Go to sdk folder sdk\tools\lib64\qt\lib. Run from this folder emulator with options -writable-system -selinux disabled Like this:

F:\android\sdk\tools\lib64\qt\lib>F:\android\sdk\tools\emulator.exe -avd 7.0_x86 -verbose -writable-system -selinux disabled

2. You need restart adbd from root:

   adb -s emulator-5554 root

And remount system:

adb -s emulator-5554 remount

It can be doned only once per run emulator. And any another remount can break write mode. Because of this you not need run of any other commands with remount, like mount -o remount,rw /system.

Another steps stay same - upload binary, run binary as daemon and so on.

Picture from AVD Android 7 x86 with root:

If you see error about PIE on execute su binary - then you upload to emulator wrong binary. You must upload binary named su.pie inside archive, but on emulator it must be named as su, not su.pie.

This is how use SignarR in order to target a specific user (without using any provider):

 private static ConcurrentDictionary<string, string> clients = new ConcurrentDictionary<string, string>();

 public string Login(string username)
 {
     clients.TryAdd(Context.ConnectionId, username);            
     return username;
 }

// The variable 'contextIdClient' is equal to Context.ConnectionId of the user, 
// once logged in. You have to store that 'id' inside a dictionaty for example.  
Clients.Client(contextIdClient).send("Hello!");

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

If you are talking about cache that is been used for caching of templates without reloading whole page, then you can empty it by something like:

.controller('mainCtrl', function($scope, $templateCache) {
  $scope.clearCache = function() { 
    $templateCache.removeAll();
  }
});

And in markup:

<button ng-click='clearCache()'>Clear cache</button>

And press this button to clear cache.

You can create an interface, pass it to AsyncTask (in constructor), and then call method in onPostExecute()

For example:

Your interface:

public interface OnTaskCompleted{
    void onTaskCompleted();
}

Your Activity:

public class YourActivity implements OnTaskCompleted{
    // your Activity
}

And your AsyncTask:

public class YourTask extends AsyncTask<Object,Object,Object>{ //change Object to required type
    private OnTaskCompleted listener;

    public YourTask(OnTaskCompleted listener){
        this.listener=listener;
    }

    // required methods

    protected void onPostExecute(Object o){
        // your stuff
        listener.onTaskCompleted();
    }
}

EDIT

Since this answer got quite popular, I want to add some things.

If you're a new to Android development, AsyncTask is a fast way to make things work without blocking UI thread. It does solves some problems indeed, there is nothing wrong with how the class works itself. However, it brings some implications, such as:

• Possibility of memory leaks. If you keep reference to your Activity, it will stay in memory even after user left the screen (or rotated the device).
• AsyncTask is not delivering result to Activity if Activity was already destroyed. You have to add extra code to manage all this stuff or do you operations twice.
• Convoluted code which does everything in Activity

When you feel that you matured enough to move on with Android, take a look at this article which, I think, is a better way to go for developing your Android apps with asynchronous operations.

The add method that takes a String and a Person is calling a different add method that takes a Position. The one that takes Position is inherited from the ArrayList class.

Since your class Staff extends ArrayList<Position>, it automatically has the add(Position) method. The new add(String, Person) method is one that was written particularly for the Staff class.

A good way of going about this is not to use nargin, but to check whether the variables have been set using exist('opt', 'var').

Example:

function [a] = train(x, y, opt)
    if (~exist('opt', 'var'))
        opt = true;
    end
end

See this answer for pros of doing it this way: How to check whether an argument is supplied in function call?

foreach(DataRow row in dataTable.Rows)

You can just use the error function that's built in to the math library, as stated on their website.

absolute = abs(x)
rounded = round(absolute)
if absolute - rounded == 0:
  print 'Integer number'
else:
  print 'notInteger number'

Inline styles cannot currently contain anything other than declarations (property: value pairs).

You can use style elements with appropriate media attributes in head section of your document.

you can use jquery validator for that but you need to add jquery.validate.js and jquery.form.js file for that. after including validator file define your validation something like this.

<script type="text/javascript">
$(document).ready(function(){
    $("#formID").validate({
    rules :{
        "data[User][name]" : {
            required : true
        }
    },
    messages :{
        "data[User][name]" : {
            required : 'Enter username'
        }
    }
    });
});
</script>

You can see required : true same there is many more property like for email you can define email : true for number number : true

None of the above worked for me. This works for me:

$username = $form["username"]->getData();
$password = $form["password"]->getData();

I hope it helps.

$firstname = $_POST["firstname"];
$lastname = $_POST["lastname"];
$email = $_POST["email"];
$pass = $_POST["password"];

$check_email = mysqli_query($conn, "SELECT Email FROM crud where Email = '$email' ");
if(mysqli_num_rows($check_email) > 0){
    echo('Email Already exists');
}
else{
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $result = mysqli_query($conn, "INSERT INTO crud (Firstname, Lastname, Email, Password) VALUES ('$firstname', '$lastname', '$email', '$pass')");
}
    echo('Record Entered Successfully');
}

break;.

while(choice!=99)
{
   cin>>choice;
   if (choice==99)
       break;
   cin>>gNum;
}

Yes you can use the ?GetValue???s method:

var values = Enum.GetValues(typeof(Foos));

Or the typed version:

var values = Enum.GetValues(typeof(Foos)).Cast<Foos>();

I long ago added a helper function to my private library for just such an occasion:

public static class EnumUtil {
    public static IEnumerable<T> GetValues<T>() {
        return Enum.GetValues(typeof(T)).Cast<T>();
    }
}

Usage:

var values = EnumUtil.GetValues<Foos>();

Probably because of optimizations. Excel 2007 can have a maximum of 16 384 columns and 1 048 576 rows. Strange numbers?

14 bits = 16 384, 20 bits = 1 048 576

14 + 20 = 34 bits = more than one 32 bit register can hold.

But they also need to store the format of the cell (text, number etc) and formatting (colors, borders etc). Assuming they use two 32-bit words (64 bit) they use 34 bits for the cell number and have 30 bits for other things.

Why is that important? In memory they don't need to allocate all the memory needed for the whole spreadsheet but only the memory necessary for your data, and every data is tagged with in what cell it is supposed to be in.

Update 2016:

Found a link to Microsoft's specification for Excel 2013 & 2016

• Open workbooks: Limited by available memory and system resources
• Worksheet size: 1,048,576 rows (20 bits) by 16,384 columns (14 bits)
• Column width: 255 characters (8 bits)
• Row height: 409 points
• Page breaks: 1,026 horizontal and vertical (unexpected number, probably wrong, 10 bits is 1024)
• Total number of characters that a cell can contain: 32,767 characters (signed 16 bits)
• Characters in a header or footer: 255 (8 bits)
• Sheets in a workbook: Limited by available memory (default is 1 sheet)
• Colors in a workbook: 16 million colors (32 bit with full access to 24 bit color spectrum)
• Named views in a workbook: Limited by available memory
• Unique cell formats/cell styles: 64,000 (16 bits = 65536)
• Fill styles: 256 (8 bits)
• Line weight and styles: 256 (8 bits)
• Unique font types: 1,024 (10 bits) global fonts available for use; 512 per workbook
• Number formats in a workbook: Between 200 and 250, depending on the language version of Excel that you have installed
• Names in a workbook: Limited by available memory
• Windows in a workbook: Limited by available memory
• Hyperlinks in a worksheet: 66,530 hyperlinks (unexpected number, probably wrong. 16 bits = 65536)
• Panes in a window: 4
• Linked sheets: Limited by available memory
• Scenarios: Limited by available memory; a summary report shows only the first 251 scenarios
• Changing cells in a scenario: 32
• Adjustable cells in Solver: 200
• Custom functions: Limited by available memory
• Zoom range: 10 percent to 400 percent
• Reports: Limited by available memory
• Sort references: 64 in a single sort; unlimited when using sequential sorts
• Undo levels: 100
• Fields in a data form: 32
• Workbook parameters: 255 parameters per workbook
• Items displayed in filter drop-down lists: 10,000

It would be something like this

function CustomInputBox([string] $title, [string] $message, [string] $defaultText) 
{
$inputObject = new-object -comobject MSScriptControl.ScriptControl
$inputObject.language = "vbscript" 
$inputObject.addcode("function getInput() getInput = inputbox(`"$message`",`"$title`" , `"$defaultText`") end function" ) 
$_userInput = $inputObject.eval("getInput") 

return $_userInput
}

Then you can call the function similar to this.

$userInput = CustomInputBox "User Name" "Please enter your name." ""
if ( $userInput -ne $null ) 
{
 echo "Input was [$userInput]"
}
else
{
 echo "User cancelled the form!"
}

This is the most simple way to do this that I can think of.

Quote from the Spring reference doc:

Upon initialization of a DispatcherServlet, Spring MVC looks for a file named [servlet-name]-servlet.xml in the WEB-INF directory of your web application and creates the beans defined there...

Your servlet is called spring-dispatcher, so it looks for /WEB-INF/spring-dispatcher-servlet.xml. You need to have this servlet configuration, and define web related beans in there (like controllers, view resolvers, etc). See the linked documentation for clarification on the relation of servlet contexts to the global application context (which is the app-config.xml in your case).

One more thing, if you don't like the naming convention of the servlet config xml, you can specify your config explicitly:

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

To get the shape as a list of ints, do tensor.get_shape().as_list().

To complete your tf.shape() call, try tensor2 = tf.reshape(tensor, tf.TensorShape([num_rows*num_cols, 1])). Or you can directly do tensor2 = tf.reshape(tensor, tf.TensorShape([-1, 1])) where its first dimension can be inferred.

That's the error you get when the DLL itself requires another COM server to be registered first or has a dependency on another DLL that's not available. The Regsvr32.exe tool does very little, it calls LoadLibrary() to load the DLL that's passed in the command line argument. Then GetProcAddress() to find the DllRegisterServer() entry point in the DLL. And calls it to leave it up to the COM server to register itself.

What that code does is fairly unguessable. The diagnostic you got is however pretty self-evident from the error code, for some reason this COM server needs another one to be registered first. The error message is crappy, it doesn't tell you what other server it needs. A sad side-effect of the way COM error handling works.

To troubleshoot this, use SysInternals' ProcMon tool. It shows you what registry keys Regsvr32.exe (actually: the COM server) is opening to find the server. Look for accesses to the CLSID key. That gives you a hint what {guid} it is looking for. That still doesn't quite tell you the server DLL, you should compare the trace with one you get from a machine that works. The InprocServer32 key has the DLL path.

The div tag is a block element, causing that behavior.

You should use a span element instead, which is inline.

If you really want to use div, add style="display: inline". (You can also put that in a CSS rule)

Yeah in simulator. Some times it wont recognise the selector there is a bug it seems. Even i faced not for your code , then i just changed the action name (selector). It works

let buttonPuzzle:UIButton = UIButton(frame: CGRectMake(100, 400, 100, 50))
buttonPuzzle.backgroundColor = UIColor.greenColor()
buttonPuzzle.setTitle("Puzzle", forState: UIControlState.Normal)
buttonPuzzle.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
buttonPuzzle.tag = 22;
self.view.addSubview(buttonPuzzle)

An example selector function is here:

func buttonAction(sender:UIButton!) {
    var btnsendtag:UIButton = sender
    if btnsendtag.tag == 22 {            
        //println("Button tapped tag 22")
    }
}

In Python, you can use this code for automatic PostgreSQL table creation with column names:

import pandas, csv

from io import StringIO
from sqlalchemy import create_engine

def psql_insert_copy(table, conn, keys, data_iter):
    dbapi_conn = conn.connection
    with dbapi_conn.cursor() as cur:
        s_buf = StringIO()
        writer = csv.writer(s_buf)
        writer.writerows(data_iter)
        s_buf.seek(0)
        columns = ', '.join('"{}"'.format(k) for k in keys)
        if table.schema:
            table_name = '{}.{}'.format(table.schema, table.name)
        else:
            table_name = table.name
        sql = 'COPY {} ({}) FROM STDIN WITH CSV'.format(table_name, columns)
        cur.copy_expert(sql=sql, file=s_buf)

engine = create_engine('postgresql://user:password@localhost:5432/my_db')

df = pandas.read_csv("my.csv")
df.to_sql('my_table', engine, schema='my_schema', method=psql_insert_copy)

It's also relatively fast, I can import more than 3.3 million rows in about 4 minutes.

An example of complete solution

Declare a json file which contains mapping you want

{
  "old_key_name": "new_key_name",
  "old_key_name_2": "new_key_name_2",
}

Load it

with open("<filepath>") as json_file:
    format_dict = json.load(json_file)

Create this function to format a dict with your mapping

def format_output(dict_to_format,format_dict):
  for row in dict_to_format:
    if row in format_dict.keys() and row != format_dict[row]:
      dict_to_format[format_dict[row]] = dict_to_format.pop(row)
  return dict_to_format

You should use the excellent OpenCSV for reading and writing CSV files. To adapt your example to use the library it would look like this:

public class ParseCSV {
  public static void main(String[] args) {
    try {
      //csv file containing data
      String strFile = "C:/Users/rsaluja/CMS_Evaluation/Drupal_12_08_27.csv";
      CSVReader reader = new CSVReader(new FileReader(strFile));
      String [] nextLine;
      int lineNumber = 0;
      while ((nextLine = reader.readNext()) != null) {
        lineNumber++;
        System.out.println("Line # " + lineNumber);

        // nextLine[] is an array of values from the line
        System.out.println(nextLine[4] + "etc...");
      }
    }
  }
}

Save into LocalStorage:

localStorage.setItem('key', value);

For objects with properties:

localStorage.setItem('key', JSON.stringify(object));

Get From Local Storage:

localStorage.getItem('key');

For objects:

JSON.parse(localStorage.getItem('key'));

localStorage Object will save data as string and retrieve as string. You need to Parse desired output if value is object stored as string. e.g. parseInt(localStorage.getItem('key'));

It is better to use framework provided localStroage instead of 3rd party library localStorageService or anything else because it reduces your project size.

Changing

RestResponse response = client.Execute(request);

to

IRestResponse response = client.Execute(request);

worked for me.

Yes, it can be done.
It is based on the new html5 "download" attribute of anchor tags.
The flow should be something like this :

1. load the image
2. draw the image into a canvas with the crop boundaries specified
3. get the image data from the canvas and make it a href attribute for an anchor tag in the dom
4. add the download attribute (download="desired-file-name") to that a element That's it. all the user has to do is click your "download link" and the image will be downloaded to his pc.

I'll come back with a demo when I get the chance.

Update
Here's the live demo as I promised. It takes the jsfiddle logo and crops 5px of each margin.
The code looks like this :

var img = new Image();
img.onload = function(){
    var cropMarginWidth = 5,
        canvas = $('<canvas/>')
                    .attr({
                         width: img.width - 2 * cropMarginWidth,
                         height: img.height - 2 * cropMarginWidth
                     })
                    .hide()
                    .appendTo('body'),
        ctx = canvas.get(0).getContext('2d'),
        a = $('<a download="cropped-image" title="click to download the image" />'),
        cropCoords = {
            topLeft : {
                x : cropMarginWidth,
                y : cropMarginWidth 
            },
            bottomRight :{
                x : img.width - cropMarginWidth,
                y : img.height - cropMarginWidth
            }
        };

    ctx.drawImage(img, cropCoords.topLeft.x, cropCoords.topLeft.y, cropCoords.bottomRight.x, cropCoords.bottomRight.y, 0, 0, img.width, img.height);
    var base64ImageData = canvas.get(0).toDataURL();


    a
        .attr('href', base64ImageData)
        .text('cropped image')
        .appendTo('body');

    a
        .clone()
        .attr('href', img.src)
        .text('original image')
        .attr('download','original-image')
        .appendTo('body');

    canvas.remove();
}
img.src = 'some-image-src';

Update II
Forgot to mention : of course there is a downside :(.
Because of the same-origin policy that is applied to images too, if you want to access an image's data (through the canvas method toDataUrl).
So you would still need a server-side proxy that would serve your image as if it were hosted on your domain.

Update III Although I can't provide a live demo for this (for security reasons), here is a php sample code that solves the same-origin policy :

file proxy.php :

$imgData = getimagesize($_GET['img']);
header("Content-type: " . $imgData['mime']);
echo file_get_contents($_GET['img']);  

This way, instead of loading the external image direct from it's origin :

img.src = 'http://some-domain.com/imagefile.png';

You can load it through your proxy :

img.src = 'proxy.php?img=' + encodeURIComponent('http://some-domain.com/imagefile.png');  

And here's a sample php code for saving the image data (base64) into an actual image :

file save-image.php :

$data = preg_replace('/data:image\/(png|jpg|jpeg|gif|bmp);base64/','',$_POST['data']);
$data = base64_decode($data);
$img = imagecreatefromstring($data);

$path = 'path-to-saved-images/';
// generate random name
$name  = substr(md5(time()),10);
$ext = 'png';
$imageName = $path.$name.'.'.$ext;

// write the image to disk
imagepng($img,  $imageName);
imagedestroy($img);
// return the image path
echo $imageName;

All you have to do then is post the image data to this file and it will save the image to disc and return you the existing image filename.

Of course all this might feel a bit complicated, but I wanted to show you that what you're trying to achieve is possible.

If you've followed Adam's instructions and you're still getting this error make sure you've installed the right variants (x86 or x64).

I had VC14x64 with PHP7x86 and I still got this error. Changing PHP7 to x64 fixed it. It's easy to miss you accidentally installed the wrong version.

Try this:

PM> Enable-migrations -force
PM> Add-migration MigrationName
PM> Update-database -force

The general solution could be a caching iterator. A properly implemented caching iterator works with any Iterator, and saves memory. PHP SPL has a CachingIterator, but it is very odd, and has very limited functionality. However, you can write your own lookahead iterator like this:

<?php

class NeighborIterator implements Iterator
{

    protected $oInnerIterator;

    protected $hasPrevious = false;
    protected $previous = null;
    protected $previousKey = null;

    protected $hasCurrent = false;
    protected $current = null;
    protected $currentKey = null;

    protected $hasNext = false;
    protected $next = null;
    protected $nextKey = null;

    public function __construct(Iterator $oInnerIterator)
    {
        $this->oInnerIterator = $oInnerIterator;
    }

    public function current()
    {
        return $this->current;
    }

    public function key()
    {
        return $this->currentKey;
    }

    public function next()
    {
        if ($this->hasCurrent) {
            $this->hasPrevious = true;
            $this->previous = $this->current;
            $this->previousKey = $this->currentKey;
            $this->hasCurrent = $this->hasNext;
            $this->current = $this->next;
            $this->currentKey = $this->nextKey;
            if ($this->hasNext) {
                $this->oInnerIterator->next();
                $this->hasNext = $this->oInnerIterator->valid();
                if ($this->hasNext) {
                    $this->next = $this->oInnerIterator->current();
                    $this->nextKey = $this->oInnerIterator->key();
                } else {
                    $this->next = null;
                    $this->nextKey = null;
                }
            }
        }
    }

    public function rewind()

            $this->currentKey = $this->oInnerIterator->key();
            $this->oInnerIterator->next();
            $this->hasNext = $this->oInnerIterator->valid();
            if ($this->hasNext) {

Copy the btn_check.xml from android-sdk/platforms/android-#/data/res/drawable to your project's drawable folder and change the 'on' and 'off' image states to your custom images.

Then your xml will just need android:button="@drawable/btn_check"

<CheckBox
    android:button="@drawable/btn_check"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true" />

If you want to use different default android icons, you can use android:button="@android:drawable/..."

Master:

mysqldump -u root -p --all-databases --master-data | gzip > /tmp/dump.sql.gz  

scp master:/tmp/dump.sql.gz slave:/tmp/ Move dump file to slave server

Slave:

STOP SLAVE;

zcat /tmp/dump.sql.gz | mysql -u root -p

START SLAVE;
SHOW SLAVE STATUS;  

NOTE:
On master you can run SET GLOBAL expire_logs_days = 3 to keep binlogs for 3 days in case of slave issues.

Either != or ne will work, but you need to get the accessor syntax and nested quotes sorted out.

    <%-- snip --%>
</c:if>

A different base R alternative would be to first order by id and stopSequence, split them based on id and for every id we select only the first and last index and subset the dataframe using those indices.

df[sapply(with(df, split(order(id, stopSequence), id)), function(x) 
                   c(x[1], x[length(x)])), ]


#  id stopId stopSequence
#1  1      a            1
#3  1      c            3
#5  2      b            1
#6  2      c            4
#8  3      b            1
#7  3      a            3

Or similar using by

df[unlist(with(df, by(order(id, stopSequence), id, function(x) 
                   c(x[1], x[length(x)])))), ]

Your compound PRIMARY KEY specification already does what you want. Omit the line that's giving you a syntax error, and omit the redundant CONSTRAINT (already implied), too:

               tag3 VARCHAR(20),
               PRIMARY KEY(question_id, tag_id)
      );

Intellij IDEA 15: File->Project Structure...->Project Settings->Libraries

@Andrea Tulimiero 's answer works for local, but when you ssh to a remote server, the beep turns on again. My suggestion is to disable from the Windows 10 taskbar. There is volume mixer in the right bottom corner, which works for me.

As it is, both dimensions of your vector are 0.

Instead, initialize the vector as this:

vector<vector<int> > matrix(RR);
for ( int i = 0 ; i < RR ; i++ )
   matrix[i].resize(CC);

This will give you a matrix of dimensions RR * CC with all elements set to 0.

You can create this 'half-gradient' look by using an xml Layer-List to combine the top and bottom 'bands' into one file. Each band is an xml shape.

See this previous answer on SO for a detailed tutorial: Multi-gradient shapes.

I was using csv-parse but for larger files was running into performance issues one of the better libraries I have found is Papa Parse, docs are good, good support, lightweight, no dependencies.

Install papaparse

npm install papaparse

Usage:

• async / await

const fs = require('fs');
const Papa = require('papaparse');

const csvFilePath = 'data/test.csv'

// Function to read csv which returns a promise so you can do async / await.

const readCSV = async (filePath) => {
  const csvFile = fs.readFileSync(filePath)
  const csvData = csvFile.toString()  
  return new Promise(resolve => {
    Papa.parse(csvData, {
      header: true,
      transformHeader: header => header.trim(),
      complete: results => {
        console.log('Complete', results.data.length, 'records.'); 
        resolve(results.data);
      }
    });
  });
};

const test = async () => {
  let parsedData = await readCSV(csvFilePath); 
}

test()

• callback

const fs = require('fs');
const Papa = require('papaparse');

const csvFilePath = 'data/test.csv'

const file = fs.createReadStream(csvFilePath);

var csvData=[];
Papa.parse(file, {
  header: true,
  transformHeader: header => header.trim(),
  step: function(result) {
    csvData.push(result.data)
  },
  complete: function(results, file) {
    console.log('Complete', csvData.length, 'records.'); 
  }
});

Note header: true is an option on the config, see docs for other options

You can use sys.exit() to exit from the middle of the main function.

However, I would recommend not doing any logic there. Instead, put everything in a function, and call that from __main__ - then you can use return as normal.

public static void main(String[] args)
 {
     int rem,n=702,quo;
     String s=" ";
     while(n>0)
     {
         rem=(n-1)%26;
         quo=(n-1)/26;
         s=(char)(rem+97)+s;
         if(quo==1)
         {
            s=(char)(97)+s;
            break;
         }
         else
         n=(n-1)/26;
     }
     System.out.print(s);
 }
}
////We can also write the code like the below one. There is no much difference but it may help to understand the concept for some people.


public static void main(String[] args)
 {
     int rem,n=52,quo;
     String s=" ";
     while(n>0)
     {
         rem=n%26;
         quo=n/26;
         if(rem==0)
             rem=26;
         s=(char)(rem+96)+s;
         if((quo==1 || quo==0) && n>26)
         {
             n=n/26;
            s=(char)(n+96)+s;
            break;
         }
         else
             n=n/26-1; 
     }
     System.out.print(s);
 }

I sometimes like using the array_reduce() function to carry out the search. It's similar to array_filter() but does not affect the searched array, allowing you to carry out multiple searches on the same array of objects.

$haystack = array($obj1, $obj2, ...); //some array of objects
$needle = 'looking for me?'; //the value of the object's property we want to find

//carry out the search
$search_results_array = array_reduce(
  $haystack,

  function($result_array, $current_item) use ($needle){
      //Found the an object that meets criteria? Add it to the the result array 
      if ($current_item->someProperty == $needle){
          $result_array[] = $current_item;
      }
      return $result_array;
  },
  array() //initially the array is empty (i.e.: item not found)
);

//report whether objects found
if (count($search_results_array) > 0){
  echo "found object(s): ";
  print_r($search_results_array[0]); //sample object found
} else {
  echo "did not find object(s): ";
}

Remove the below code it will work

 super.onReceivedSslError(view, handler, error);

compile and running as per documentation of sublime text 2 nd 3

step- 1: set environment variables for java as u know already or refer somewhere

strp-2: open new document and copy paste code below

{
"cmd": ["javac", "$file_name", "&&", "java", "$file_base_name"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.java",
"shell":true }

step-3: save the document as userjavaC.sublime-build in directory C:\Users\myLapi\AppData\Roaming\Sublime Text 3\Packages\User

step-4:

after done select as tools->build systems->userjavaC

to both compile and run press ctrl+b

[root]# cat time.c

#include <time.h>

int main(int argc, char** argv)
{
        time_t test;
        return 0;
}

[root]# gcc -E time.c | grep __time_t

typedef long int __time_t;

It's defined in $INCDIR/bits/types.h through:

# 1 "/usr/include/bits/typesizes.h" 1 3 4
# 132 "/usr/include/bits/types.h" 2 3 4

I was struggling, but the below worked for me finally!

Dim WB As Workbook

Set WB = Workbooks.Open("\\users\path\Desktop\test.xlsx")

WB.SaveAs fileName:="\\users\path\Desktop\test.xls", _
        FileFormat:=xlExcel8, Password:="", WriteResPassword:="", _
        ReadOnlyRecommended:=False, CreateBackup:=False

I aso find this extremely confusing. as @EricMartinez points out Renderer2 listen() returns the function to remove the listener:

ƒ () { return element.removeEventListener(eventName, /** @type {?} */ (handler), false); }

If i´m adding a listener

this.listenToClick = this.renderer.listen('document', 'click', (evt) => {
    alert('Clicking the document');
})

I´d expect my function to execute what i intended, not the total opposite which is remove the listener.

// I´d expect an alert('Clicking the document'); 
this.listenToClick();
// what you actually get is removing the listener, so nothing...

In the given scenario, It´d actually make to more sense to name it like:

// Add listeners
let unlistenGlobal = this.renderer.listen('document', 'click', (evt) => {
    console.log('Clicking the document', evt);
})

let removeSimple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
    console.log('Clicking the button', evt);
});

There must be a good reason for this but in my opinion it´s very misleading and not intuitive.

I agree it is generally preferable to use an Array for this.

However, this can also be accomplished in JavaScript by simply adding properties to the current scope (the global scope, if top-level code; the function scope, if within a function) by simply using this – which always refers to the current scope.

for (var i = 0; i < coords.length; ++i) {
    this["marker"+i] = "some stuff";
}

You can later retrieve the stored values (if you are within the same scope as when they were set):

var foo = this.marker0;
console.log(foo); // "some stuff"

This slightly odd feature of JavaScript is rarely used (with good reason), but in certain situations it can be useful.

You can also use the unix style time to calculate:

$newtime = time() + ($hours * 60 * 60); // hours; 60 mins; 60secs
echo 'Now:       '. date('Y-m-d') ."\n";
echo 'Next Week: '. date('Y-m-d', $newtime) ."\n";

strtok can be very dangerous. It is not thread safe. Its intended use is to be called over and over in a loop, passing in the output from the previous call. The strtok function has an internal variable that stores the state of the strtok call. This state is not unique to each thread - it is global. If any other code uses strtok in another thread, you get problems. Not the kind of problems you want to track down either!

I'd recommend looking for a regex implementation, or using sscanf to pull apart the string.

Try this:

char strprint[256];
char text[256];
strcpy(text, "My string to test");
while ( sscanf( text, "%s %s", strprint, text) > 0 ) {
   printf("token: %s\n", strprint);
}

Note: The 'text' string is destroyed as it's separated. This may not be the preferred behaviour =)

Clearing my browser's cache fixed this issue for me. I had been switching between local development environments to do the django-blog-zinnia tutorial after working on another project when it happened. At first, I thought changing the order of INSTALLED_APPS to match the tutorial had caused it, but I set these back and was unable to correct it until clearing the cache.

If you're looking for a pure css option, try using the :focus pseudo class.

#style  {
    background-color: red;
}

#style:focus {     
    background-color:yellow;    
}

Whether something is a "checked exception" has nothing to do with whether you catch it or what you do in the catch block. It's a property of exception classes. Anything that is a subclass of Exception except for RuntimeException and its subclasses is a checked exception.

The Java compiler forces you to either catch checked exceptions or declare them in the method signature. It was supposed to improve program safety, but the majority opinion seems to be that it's not worth the design problems it creates.

Why do they let the exception bubble up? Isnt handle error the sooner the better? Why bubble up?

Because that's the entire point of exceptions. Without this possibility, you would not need exceptions. They enable you to handle errors at a level you choose, rather than forcing you to deal with them in low-level methods where they originally occur.

If you are using Spring Security ver >= 4.2 you can use Spring Security's native support instead of including Apache's:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

The example above was copied from a Spring blog post in which you also can find information about how to configure CORS on a controller, specific controller methods, etc. Moreover, there is also XML configuration examples as well as Spring Boot integration.

You are getting that error because when the param1 if statements are evaluated, param is always null due to being scoped variables without delayed expansion.

When parentheses are used, all the commands and variables within those parentheses are expanded. And at that time, param1 has no value making the if statements invalid. When using delayed expansion, the variables are only expanded when the command is actually called.

Also I recommend using if not defined command to determine if a variable is set.

@echo off
setlocal EnableExtensions EnableDelayedExpansion

As You're getting values from textfield as jTextField3.getText();.

As it is a textField it will return you string format as its format says:

String getText()

      Returns the text contained in this TextComponent.

So, convert your String to Integer as:

int jml = Integer.parseInt(jTextField3.getText());

instead of directly setting

   int jml = jTextField3.getText();

This SP looks very strange. It does not modify what is passed to @b. And nowhere in the SP you assign anything to @b. And @Password is not defined, so this SP will not work at all.

I would guess you actually want to return @Password, or to have SET @b = (SELECT...)

Much simpler will be if you modify your SP to (note, no OUTPUT parameter):

set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go

ALTER PROCEDURE [dbo].[Validate] @a varchar(50)

AS

SELECT TOP 1 Password FROM dbo.tblUser WHERE Login = @a

Then, your code can use cmd.ExecuteScalar, and receive the result.

You array is being allocated on the stack in this case attempt to allocate an array of the same size using alloc.

Just use \w or [:alpha:]. It is an escape sequences which matches only symbols which might appear in words.

JsonConvert is from the namespace Newtonsoft.Json, not System.ServiceModel.Web

Use NuGet to download the package

"Project" -> "Manage NuGet packages" -> "Search for "newtonsoft json". -> click "install".

Deleting the .git folder is probably the easiest path since you don't want/need the history (as Stephan said).

So you can create a new repo from your latest commit: (How to clone seed/kick-start project without the whole history?)

git clone <git_url>

then delete .git, and afterwards run

git init

Or if you want to reuse your current repo: Make the current commit the only (initial) commit in a Git repository?

Follow the above steps then:

git add .
git commit -m "Initial commit"

Push to your repo.

git remote add origin <github-uri>
git push -u --force origin master

Here is an end to end solution I implemented for streaming Android microphone audio to a server for playback: Android AudioRecord to Server over UDP Playback Issues

Accessing localhost from the iPhone will simply do a loopback / try to connect to itself (If it supports that?).

What you need to do is find the IP of your desktop machine (e.g. If Windows, go to the Command Prompt and type ipconfig or go to Network and Sharing Centre and look up connection status.

Once you have your ip, simply visit that from your browser e.g. http://192.168.0.102.

You may need to open up port 80 (or whatever port your website is running on) in the inbound security of your firewall if you are running one.

Note: don't forget the app's port if what you want is to debug the app in your iPhone's browser like: http://192.168.0.102:3000. In this example 3000 is the default port used by ReactJS.

jsonObj.profile-id is a subtraction expression (i.e. jsonObj.profile - id).

To access a key that contains characters that cannot appear in an identifier, use brackets:

jsonObj["profile-id"]

Use substring() and give the number of characters that you want to trim from front.

String value = "Jamaica";
value = value.substring(1);

Answer: "amaica"

I got the same error in Chrome console.

My problem was, I was trying to go to the site using http:// instead of https://. So there was nothing to fix, just had to go to the same site using https.

I second @erickson: The pure data-transfer speed penalty is negligible. Modern CPUs reach a crypto/AES throughput of several hundred MBit/s. So unless you are on resource constrained system (mobile phone) TLS/SSL is fast enough for slinging data around.

But keep in mind that encryption makes caching and load balancing much harder. This might result in a huge performance penalty.

But connection setup is really a show stopper for many application. On low bandwidth, high packet loss, high latency connections (mobile device in the countryside) the additional roundtrips required by TLS might render something slow into something unusable.

For example we had to drop the encryption requirement for access to some of our internal web apps - they where next to unusable if used from china.

• Lets say 1st component is DbstatsMainComponent
• 2nd component DbstatsGraphComponent.
• 1st component calling the method of 2nd

<button (click)="dbgraph.displayTableGraph()">Graph</button> <dbstats-graph #dbgraph></dbstats-graph>

Note the local variable #dbgraph on the child component, which the parent can use to access its methods (dbgraph.displayTableGraph()).

I am using ansible 2.5 (2.5.3 exactly), and it seems that the vars file is loaded before the hosts param is executed. So you can set the host in a vars.yml file and just write hosts: {{ host_var }} in your playbook

For example, in my playbook.yml:

---
- hosts: "{{ host_name }}"
  become: yes
  vars_files:
    - vars/project.yml
  tasks:
    ... 

And inside vars/project.yml:

---

# general
host_name: your-fancy-host-name

having to pass context around everywhere is really annoying me. the code becomes too verbose and unmanageable. I do this in every project instead...

public class global {
    public static Activity globalContext = null;

and set it in the main activity create

@Override
public void onCreate(Bundle savedInstanceState) {
    Thread.setDefaultUncaughtExceptionHandler(new CustomExceptionHandler(
            global.sdcardPath,
            ""));
    super.onCreate(savedInstanceState);

    //Start 
    //Debug.startMethodTracing("appname.Trace1");

    global.globalContext = this;

also all preference keys should be language independent, I'm shocked nobody has mentioned that.

getText(R.string.yourPrefKeyName).toString()

now call it very simply like this in one line of code

global.globalContext.getSharedPreferences(global.APPNAME_PREF, global.MODE_PRIVATE).getBoolean("isMetric", true);

Someone with a requirement where they have to read from bits, lets say you have to read from only 3 bits but you need signed integer then use following:

data is of type: java.util.BitSet

new BigInteger(data.toByteArray).intValue() << 32 - 3 >> 32 - 3

The magic number 3 can be replaced with the number of bits (not bytes) you are using.

I use this :

1-Declare a temp table variable in the script your building:

DECLARE @ShiftPeriodList TABLE(id INT NOT NULL);

2-Allocate to temp table:

IF (SOME CONDITION) 
BEGIN 
        INSERT INTO @ShiftPeriodList SELECT ShiftId FROM [hr].[tbl_WorkShift]
END
IF (SOME CONDITION2)
BEGIN
    INSERT INTO @ShiftPeriodList
        SELECT  ws.ShiftId
        FROM [hr].[tbl_WorkShift] ws
        WHERE ws.WorkShift = 'Weekend(VSD)' OR ws.WorkShift = 'Weekend(SDL)'

END

3-Reference the table when you need it in a WHERE statement :

INSERT INTO SomeTable WHERE ShiftPeriod IN (SELECT * FROM @ShiftPeriodList)

You need to write this in the command prompt:

set HTTP_PROXY=http://your_proxy:your_port

That method will not work. The <title> only supports plain text. You will need to create an .ico image with the filename of favicon.ico and save it into the root folder of your site (where your default page is).

Alternatively, you can save the icon where ever you wish and call it whatever you want, but simply insert the following code into the <head> section of your HTML and reference your icon:

<link rel="shortcut icon" href="your_image_path_and_name.ico" />

You can use Photoshop (with a plug in) or GIMP (free) to create an .ico file, or you can just use IcoFX, which is my personal favourite as it is really easy to use and does a great job (you can get an older version of the software for free from download.com).

Update 1: You can also use a number of online tools to create favicons such as ConvertIcon, which I've used successfully. There are other free online tools available now too, which do the same (accessible by a simple Google search), but also generate other icons such as the Windows 8/10 Start Menu icons and iOS App Icons.

Update 2: You can also use .png images as icons providing IE11 is the only version of IE you need to support. You just need to reference them using the HTML code above. Note that IE10 and older still require .ico files.

Update 3: You can now use Emoji characters in the title field. On Windows 10, it should generally fall back and use the Segoe UI Emoji font and display nicely, however you'll need to test and see how other systems support and display your chosen emoji, as not all devices may have the same Emoji available.

Most of the other answers point to eager loading, but I found another solution.

       return ItemActivity?.OrderByDescending(x => x.DateEntered).SingleOrDefault();
   }
...
}

And since I was pulling from the child object collection instead of a context query (with IQueryable), the Include() function was not available to implement eager loading. So instead my solution was to create a context from where I utilized GetLatestActivity() and attach() the returned object:

using (DBContext ctx = new DBContext())
{
    var latestAct = _item.GetLatestActivity();

    // attach the Entity object back to a usable database context
    ctx.InventoryActivity.Attach(latestAct);

    // your code that would make use of the latestAct's lazy loading
    // ie   latestAct.lazyLoadedChild.name = "foo";
}

Thus you aren't stuck with eager loading.

def f(dic):
    if 'a' in dic:
        print dic['a'],
        pass
    else: print 'None',

    if 'b' in dic:
        print dic['b'],
        pass
    else: print 'None',

    if 'c' in dic:
        print dic['c'],
        pass
    else: print 'None',
    print
    pass
f({})
f({'a':20,
   'c':30})
f({'a':20,
   'c':30,
   'b':'red'})
____________

the above code will output

None None None
20 None 30
20 red 30

This is as good as passing variable arguments by means of a dictionary

In Ubuntu, you need to uncomment this line in file php.ini which is located at /etc/php/7.0/apache2/php.ini:

extension=php_mysqli.so

To convert a string into a date, the easiest way AFAIK is the dateutil module:

import dateutil.parser
datetime_object = dateutil.parser.parse("2013-05-07")

It can also handle time zones:

print(dateutil.parser.parse("2013-05-07"))
>>> datetime.datetime(2013, 5, 7, 1, 12, 12, tzinfo=tzutc())

If you have a datetime object, say:

import pytz
import datetime
now = datetime.datetime.now(pytz.UTC)

and you want chop off the time part, then I think it is easier to construct a new object instead of "substracting the time part". It is shorter and more bullet proof:

date_part datetime.datetime(now.year, now.month, now.day, tzinfo=now.tzinfo)

It also keeps the time zone information, it is easier to read and understand than a timedelta substraction, and you also have the option to give a different time zone in the same step (which makes sense, since you will have zero time part anyway).

This works for me:

EditText.setKeyListener(null);

vector<char> toVector( const std::string& s ) {
  string s = "apple";  
  vector<char> v(s.size()+1);
  memcpy( &v.front(), s.c_str(), s.size() + 1 );
  return v;
}
vector<char> v = toVector(std::string("apple"));

// what you were looking for (mutable)
char* c = v.data();

.c_str() works for immutable. The vector will manage the memory for you.

I see that they did not understand your question.

Answer is: add "traditional" parameter to your ajax call like this:

$.ajax({
  traditional: true,
  type: "POST",
  url: url,
  data: custom,
  success: ok,
  dataType: "json"
});

And it will work with parameters PASSED AS A STRING.

Your problem arises from the fact that $i has a blank value when your statement fails. Always quote your variables when performing comparisons if there is the slightest chance that one of them may be empty, e.g.:

if [ "$i" -ge 2 ] ; then
  ...
fi

This is because of how the shell treats variables. Assume the original example,

if [ $i -ge 2 ] ; then ...

The first thing that the shell does when executing that particular line of code is substitute the value of $i, just like your favorite editor's search & replace function would. So assume that $i is empty or, even more illustrative, assume that $i is a bunch of spaces! The shell will replace $i as follows:

if [     -ge 2 ] ; then ...

Now that variable substitutions are done, the shell proceeds with the comparison and.... fails because it cannot see anything intelligible to the left of -gt. However, quoting $i:

if [ "$i" -ge 2 ] ; then ...

becomes:

if [ "    " -ge 2 ] ; then ...

The shell now sees the double-quotes, and knows that you are actually comparing four blanks to 2 and will skip the if.

You also have the option of specifying a default value for $i if $i is blank, as follows:

if [ "${i:-0}" -ge 2 ] ; then ...

This will substitute the value 0 instead of $i is $i is undefined. I still maintain the quotes because, again, if $i is a bunch of blanks then it does not count as undefined, it will not be replaced with 0, and you will run into the problem once again.

Please read this when you have the time. The shell is treated like a black box by many, but it operates with very few and very simple rules - once you are aware of what those rules are (one of them being how variables work in the shell, as explained above) the shell will have no more secrets for you.

Or you can put in the CSS,

<style>
div#img {
  background-image: url(“file.png");
  color:yellow (this part doesn't matter;
  height:100%;
  width:100%;
}
</style>

This is not supported by some browsers (IE if I recall), but it works in the rest:

document.getElementById("password-field").attributes["type"] = "password";

or

document.getElementById("password-field").attributes["type"] = "text";

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

Follow these steps:

1. Add path to gitignore file

2. Run this command

   git rm -r --cached foldername
   

3. commit changes as usually.

I've used dompdf with some success before. Although it can be a bit fussy about malformed HTML and there are still some CSS methods that aren't supported (e.g. css float does not work).

Download the package from github, and place it into a folder called dompdf in your application/thirdparty directory.

You can then create a helper with some functions to use the dompdf library, here is an example:

dompdf_helper.php :

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

function pdf_create($html, $filename='', $stream=TRUE) 
{
    include APPPATH.'thirdparty/dompdf/dompdf_config.inc.php';

    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();
    if ($stream) {
        $dompdf->stream($filename.".pdf", array("Attachment" => 0));
    } else {
        return $dompdf->output();
    }
}

You simply pass the pdf_create method your HTML as a string, the filename for the pdf file it will generate, and then an optional thirdparameter. The third parameter is a true/false flag to determine if it should save the file to your server before prompting the user to download it or not.

On my Windows 7 machine, it was solved by doing the following:

1. In the START menu type "regedit" to open the Registry (be careful doing this)
2. Go to "HKEY_LOCAL_MACHINE" on the left-hand side registry explorer/tree menu
3. Click "SOFTWARE" within the "HKEY_LOCAL_MACHINE" registries
4. Click "JavaSoft" within the "SOFTWARE" registries
5. Click "Java Runtime Environment" within the "JavaSoft" list of registries
6. Highlight "CurrentVersion" (should see it in the main registry key explorer window on the right)
7. Change version to "1.7"

That is all... should work. Short of that, if you've already tried some other guides and/or messed up your registries, the most certain way to deal with the problem is to delete all previous versions of Java (using "Programs and Features" uninstall process) and then re-install just the version you want to work with. I'd suggest the distribution site at: http://java.com (as it usually has the most stable version)

Or look for a specific version you need from Oracle's site: http://www.oracle.com/technetwork/java/javase/downloads/

The application automatically stops when the last Stage is closed. At this moment, the stop() method of your Application class is called, so you don't need an equivalent to setDefaultCloseOperation()

If you want to stop the application before that, you can call Platform.exit(), for example in your onCloseRequest call.

You can have all these information on the javadoc page of Application : http://docs.oracle.com/javafx/2/api/javafx/application/Application.html

For those of you who want to execute a side-effect only if an optional is absent

i.e. an equivalent of ifAbsent() or ifNotPresent() here is a slight modification to the great answers already provided.

myOptional.ifPresentOrElse(x -> {}, () -> {
  // logic goes here
})

Use the following in command prompt to open your current location in windows explorer:

Here is the answer for those of you looking like I did all over the web trying to find out how to do this task. Uploading a photo to a server with the file name stored in a mysql database and other form data you want in your Database. Please let me know if it helped.

Firstly the form you need:

    <form method="post" action="addMember.php" enctype="multipart/form-data">
    <p>
              Please Enter the Band Members Name.
            </p>
            <p>
              Band Member or Affiliates Name:
            </p>
            <input type="text" name="nameMember"/>
            <p>
              Please Enter the Band Members Position. Example:Drums.
            </p>
            <p>
              Band Position:
            </p>
            <input type="text" name="bandMember"/>
            <p>
              Please Upload a Photo of the Member in gif or jpeg format. The file name should be named after the Members name. If the same file name is uploaded twice it will be overwritten! Maxium size of File is 35kb.
            </p>
            <p>
              Photo:
            </p>
            <input type="hidden" name="size" value="350000">
            <input type="file" name="photo"> 
            <p>
              Please Enter any other information about the band member here.
            </p>
            <p>
              Other Member Information:
            </p>
<textarea rows="10" cols="35" name="aboutMember">
</textarea>
            <p>
              Please Enter any other Bands the Member has been in.
            </p>
            <p>
              Other Bands:
            </p>
            <input type="text" name="otherBands" size=30 />
            <br/>
            <br/>
            <input TYPE="submit" name="upload" title="Add data to the Database" value="Add Member"/>
          </form>

Then this code processes you data from the form:

   <?php

// This is the directory where images will be saved
$target = "your directory";
$target = $target . basename( $_FILES['photo']['name']);

// This gets all the other information from the form
$name=$_POST['nameMember'];
$bandMember=$_POST['bandMember'];
$pic=($_FILES['photo']['name']);
$about=$_POST['aboutMember'];
$bands=$_POST['otherBands'];


// Connects to your Database
mysqli_connect("yourhost", "username", "password") or die(mysqli_error()) ;
mysqli_select_db("dbName") or die(mysqli_error()) ;

// Writes the information to the database
mysqli_query("INSERT INTO tableName (nameMember,bandMember,photo,aboutMember,otherBands)
VALUES ('$name', '$bandMember', '$pic', '$about', '$bands')") ;

// Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{

// Tells you if its all ok
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory";
}
else {

// Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>

I see you try to set ylim but you give bad values. This will change the scale of the plot (like a zoom). For example see this:

par(mfrow=c(2,1))
tN <- table(Ni <- stats::rpois(100, lambda = 5))
r <- barplot(tN, col = rainbow(20),ylim=c(0,50),main='long y-axis')
r <- barplot(tN, col = rainbow(20),main='short y axis')

Another option is to plot without axes and set them manually using axis and usr:

require(grDevices) # for colours
par(mfrow=c(1,1))
r <- barplot(tN, col = rainbow(20),main='short y axis',ann=FALSE,axes=FALSE)
usr <- par("usr")
par(usr=c(usr[1:2], 0, 20))
axis(2,at=seq(0,20,5))

Name.objects.filter(alias__gt='',alias__isnull=False)

Regarding how to get the artifact binary, Pascal Thivent's answer is it, but to also get the artifact sources jar, we can use:

mvn dependency:get -Dartifact=groupId:artifactId:version:jar:sources

e.g.

mvn dependency:get -Dartifact=junit:junit:4.12:jar:sources

This works because the artifact parameter actually consists of groupId:artifactId:version[:packaging][:classifier]. Just the packaging and classifier are optional.

With jar as packaging and sources as classifier, the maven dependency plugin understands we're asking for the sources jar, not the artifact jar.

Unfortunately for now sources jar files cannot be downloaded transitively, which does make sense, but ideally I do believe it can also respect the option downloadSources just like the maven eclipse plugin does.

I had the same problem and my solution was simple: instead of

Encoding.ASCII

use

Encoding.GetEncoding("iso-8859-1")

The answer was found here.

Edit: more solutions. This maybe more accurate one:

Encoding.GetEncoding(1252);

Also, in some cases this will work for you too if your OS default encoding matches file encoding:

Encoding.Default;

try like this. hope it works

xxxhdpi was only introduced because of the way that launcher icons are scaled on the nexus 5's launcher Because the nexus 5's default launcher uses bigger icons, xxxhdpi was introduced so that icons would still look good on the nexus 5's launcher.

I think this is what you are looking for:

df.drop('Region', axis=1).apply(lambda x: x.mean(), axis=1)

Very much agreed with @Patrik M, but the thing with Arrays.toString is that it includes "[" and "]" and "," in the output. So I'll simply use a regex to remove them from outout like this

String strOfInts = Arrays.toString(intArray).replaceAll("\\[|\\]|,|\\s", "");

and now you have a String which can be parsed back to java.lang.Number, for example,

long veryLongNumber = Long.parseLong(intStr);

Or you can use the java 8 streams, if you hate regex,

String strOfInts = Arrays
            .stream(intArray)
            .mapToObj(String::valueOf)
            .reduce((a, b) -> a.concat(",").concat(b))
            .get();

Like it's already mentioned, I would highly recommend using regular expression (in System.Text) to get this kind of job done.

In combo with a solid tool like RegexBuddy, you are looking at handling any complex text record parsing situations, as well as getting results quickly. The tool makes it real easy.

Hope that helps.

this is how I do it.

char[] myEmptyCharArray = "".toCharArray();

We can animate images in ios 5 using this simple code.

CGRect imageFrame = imageView.frame;
imageFrame.origin.y = self.view.bounds.size.height;

[UIView animateWithDuration:0.5
    delay:1.0
    options: UIViewAnimationCurveEaseOut
    animations:^{
        imageView.frame = imageFrame;
    } 
    completion:^(BOOL finished){
        NSLog(@"Done!");
    }];

There's no one answer. The standard defines minimum ranges. An int must be able to hold at least 65535. Most modern compilers however allow ints to be 32-bit values. Additionally, there's nothing preventing multiple types from having the same capacity (e.g. int and long).

That being said, the standard does say in your particular case:

0 ? +18446744073709551615

as the range for unsigned long long int.

Hello this is best sample demo app which provides facebook like slide menu. Check the code here

Although this thread dates back to 2014, the issue can still be current to many of us. Here is how I dealt with it in a jQuery 1.12 /PHP 5.6 context:

• jQuery sent its XHR request using only limited headers; only 'Origin' was sent.
• No preflight request was needed.
• The server only had to detect such a request, and add the "Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN'] header, after detecting that this was a cross-origin XHR.

PHP Code sample:

if (!empty($_SERVER['HTTP_ORIGIN'])) {
    // Uh oh, this XHR comes from outer space...
    // Use this opportunity to filter out referers that shouldn't be allowed to see this request
    if (!preg_match('@\.partner\.domain\.net$@'))
        die("End of the road if you're not my business partner.");

    // otherwise oblige
    header("Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN']);
}
else {
    // local request, no need to send a specific header for CORS
}

In particular, don't add an exit; as no preflight is needed.

I faced the same issue, I tried the below solution and it worked for me In Android SDK Manager Window, click on Tools->Options-> under "Others", check "Force https://... sources to be fetched using http://..."

In my makefile I use this:

@sed -i '/.*Revision:.*/c\'"`svn info -R main.cpp | awk '/^Rev/'`"'' README.md

PS: DO NOT forget that the -i changes actually the text in the file... so if the pattern you defined as "Revision" will change, you will also change the pattern to replace.

Example output:

Abc-Project written by John Doe

Revision: 1190

So if you set the pattern "Revision: 1190" it's obviously not the same as you defined them as "Revision:" only...

Setting the passenger.Title with a value that equals to a title.Value should work.

View:

<select [(ngModel)]="passenger.Title">
    <option *ngFor="let title of titleArray" [value]="title.Value">
      {{title.Text}}
    </option>
</select>

}

...
export class AppComponent {
    passenger: Passenger = new Passenger("Lord");

Another option:

• Download the cities database from http://download.geonames.org/export/dump/
• Add each city as a lat/long -> City mapping to a spatial index such as an R-Tree (some DBs also have the functionality)
• Use nearest-neighbour search to find the closest city for any given point

Advantages:

• Does not depend on an external server to be available
• Very fast (easily does thousands of lookups per second)

Disadvantages:

• Not automatically up to date
• Requires extra code if you want to distinguish the case where the nearest city is dozens of miles away
• May give weird results near the poles and the international date line (though there aren't any cities in those places anyway

If you want to set a default button action in a JTextField enter, you have to do this:

//put this after initComponents();

textField.addActionListener(button.getActionListeners()[0]);

It is [0] because a button can has a lot of actions, but normally just has one (ActionPerformed).

This can also occur when the path ends in a '' followed by the closing quotation mark. e.g. The following line is passed as one of the arguments and this is not right:

"c:\users\abc\"

instead pass that argument as shown below so that the last backslash is escaped instead of escaping the quotation mark.

"c:\users\abc\\"

Simply mutiply the bottom of the division by 1.0 (or as many decimal places as you want)

SET @weight= @set1 / @set2 *1.00000;

Make sure this is not code smell. Is it possible to reverse the logic and be 'inclusive' rather than 'exclusive'?

List<String> names = ....
List<String> reducedNames = ....
for (String name : names) {
   // Do something
   if (conditionToIncludeMet)
       reducedNames.add(name);
}
return reducedNames;

The situation that led me to this page involved old code that looped through a List using indecies to remove elements from the List. I wanted to refactor it to use the foreach style.

It looped through an entire list of elements to verify which ones the user had permission to access, and removed the ones that didn't have permission from the list.

List<Service> services = ...
for (int i=0; i<services.size(); i++) {
    if (!isServicePermitted(user, services.get(i)))
         services.remove(i);
}

To reverse this and not use the remove:

List<Service> services = ...
List<Service> permittedServices = ...
for (Service service:services) {
    if (isServicePermitted(user, service))
         permittedServices.add(service);
}
return permittedServices;

When would "remove" be preferred? One consideration is if gien a large list or expensive "add", combined with only a few removed compared to the list size. It might be more efficient to only do a few removes rather than a great many adds. But in my case the situation did not merit such an optimization.

Underscore _ is considered as "I don't Care" or "Throwaway" variable in Python

• The python interpreter stores the last expression value to the special variable called _.

  >>> 10 
  10
  
  >>> _ 
  10
  
  >>> _ * 3 
  30
  

• The underscore _ is also used for ignoring the specific values. If you don’t need the specific values or the values are not used, just assign the values to underscore.

  Ignore a value when unpacking

  x, _, y = (1, 2, 3)
  
  >>> x
  1
  
  >>> y 
  3
  

  Ignore the index

  for _ in range(10):     
      do_something()
  

It can be done this way as well

foreach (Company company in listofCompany.Where(d => d.Id = 1)).ToList())
                {
                    //do your stuff here
                    company.Id= 2;
                    company.Name= "Sample"
                }

just use following code

c = np.matrix([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
matrix([[1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]])

Then it will give you

you can check shape and dimension of matrix by using following code

c.shape

c.ndim

You need to get id from:

youtube.com/watch?v=VIDEO_ID

And put this in:

I hope that I helped :D
