I have had a similar problem before where it turned out to be the web brower (chrome in my case) that was the issue.

If you are using chrome, try launching it so:

For Windows:

1) Create a shortcut to Chrome on your desktop. Right-click on the shortcut and choose Properties, then switch to “Shortcut” tab.

2) In the “Target” field, append the following: –args –disable-web-security

For Mac, Open a terminal window and run this from command-line: open ~/Applications/Google\ Chrome.app/ –args –disable-web-security

Above info from:

You can use any decompiler to first decompile the file.

I had once faced a simillar problem where I didn't have source code of the application and had to make a very small change in a file.

Below is what I did:

1. Extracted the class file from the jar

2. Opened it in a decompiler (I use JD GUI, you can get it easily from many resources on internet) You may download it from here

3. You can actually view all the files in a jar using JD GUI.

4. Made changes to the file I wanted to and copied all the code from that file
5. Created a new project in eclipse with only this class (with the same package structure as in the jar), provided the original jar as library and all other dependencies.
6. Compiled the class, injected the .class file back to the jar from bin folder of my workspace
7. Tested my change, celebrated it by sipping a cup of coffee :)

That's not possible using the built-in Array.prototype.map. However, you could use a simple for-loop instead, if you do not intend to map any values:

var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
  if (myArray[i] < 10) {
    hasValueLessThanTen = true;
    break;
  }
}

Or, as suggested by @RobW, use Array.prototype.some to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:

var hasValueLessThanTen = myArray.some(function (val) { 
  return val < 10;
});

Logical OR :- returns true if at least one of the operands evaluate to true. Both operands are evaluated before apply the OR operator.

Short Circuit OR :- if left hand side operand returns true, it returns true without evaluating the right hand side operand.

import csv
cols = [' V1', ' I1'] # define your columns here, check the spaces!
data = [[] for col in cols] # this creates a list of **different** lists, not a list of pointers to the same list like you did in [[]]*len(positions) 
with open('data.csv', 'r') as f:
    for rec in csv.DictReader(f):
        for l, col in zip(data, cols):
            l.append(float(rec[col]))
print data

# [[3.0, 3.0], [0.01, 0.01]]

try this one:

GIT_TRACE=1 git pull origin master

Found this solution on another site. You can wrap the forEach in a try / catch scenario.

if(typeof StopIteration == "undefined") {
 StopIteration = new Error("StopIteration");
}

try {
  [1,2,3].forEach(function(el){
    alert(el);
    if(el === 1) throw StopIteration;
  });
} catch(error) { if(error != StopIteration) throw error; }

Yes. Try the following in your python interpreter:

and

>>>False and 3/0
False
>>>True and 3/0
ZeroDivisionError: integer division or modulo by zero

or

>>>True or 3/0
True
>>>False or 3/0
ZeroDivisionError: integer division or modulo by zero

We are developing Versile Python (VPy), an implementation for python 2.6+ and 3.x of a new ORB/RPC framework. Functional AGPL dev releases for review and testing are available. VPy has native python capabilities similar to PyRo and RPyC via a general native objects layer (code example). The product is designed for platform-independent remote object interaction for implementations of Versile Platform.

Full disclosure: I work for the company developing VPy.

I only partially agree with the top rated answer for this question. Which type of testing would you say should be the emphasis (for testers/QAs), and why?

1. I agree that: "Black box testing should be the emphasis for testers/QA."
2. I agree that White box testing should be the emphasis for developers, but I don't agree that White Box testing is just unit tests.

I agree with the definition here which states that White Box Testing method is applicable to the following levels of software testing:

• Unit Testing: For testing paths within a unit
• Integration Testing:For testing paths between units
• System Testing: For testing paths between subsystems

You can use StringUtils’s TraditionalBinarPrefix:

public static String humanReadableInt(long number) {
    return TraditionalBinaryPrefix.long2String(number, ””, 1);
}

@Raphael your solution does work. I encountered the same problem and solved it by increasing the maximum execution time to 180. There is an easier way to do it though:

1. Open the Xampp control panel

2. Click on 'config' behind 'Apache'

3. Select 'PHP (php.ini)' from the dropdown -> A file should now open in your text editor

4. Press ctrl+f and search for 'max_execution_time', you should fine a line which only says

   max_execution_time=30

5. Change 30 to a bigger number (180 worked for me), like this:

   max_execution_time=180

6. Save the file

7. 'Stop' Apache server

8. Close Xampp

9. Restart Xampp

10. 'Start' Apache server

11. Update Wordpress from the Admin dashboard

12. Enjoy ;)

Just assuming this is for a regular expression, use re.escape.

In order for that to work $time has to be a timestamp. You cannot pass in "10:00" or something like $time = date('H:i', '10:00'); which is what you seem to do, because then I get 0:30 and 1:30 as results too.

Try

$time = strtotime('10:00');

As an alternative, consider using DateTime (the below requires PHP 5.3 though):

$dt = DateTime::createFromFormat('H:i', '10:00'); // create today 10 o'clock
$dt->sub(new DateInterval('PT30M'));              // substract 30 minutes
echo $dt->format('H:i');                          // echo modified time
$dt->add(new DateInterval('PT1H'));               // add 1 hour
echo $dt->format('H:i');                          // echo modified time

or procedural if you don't like OOP

$dateTime = date_create_from_format('H:i', '10:00');
date_sub($dateTime, date_interval_create_from_date_string('30 minutes'));
echo date_format($dateTime, 'H:i');
date_add($dateTime, date_interval_create_from_date_string('1 hour'));
echo date_format($dateTime, 'H:i');

// In MyClass.h
MyClass<T>& operator+=(const MyClass<T>& classObj);


// In MyClass.cpp
template <class T>
MyClass<T>& MyClass<T>::operator+=(const MyClass<T>& classObj) {
  // ...
  return *this;
}

This is invalid for templates. The full source code of the operator must be in all translation units that it is used in. This typically means that the code is inline in the header.

Edit: Technically, according to the Standard, it is possible to export templates, however very few compilers support it. In addition, you CAN also do the above if the template is explicitly instantiated in MyClass.cpp for all types that are T- but in reality, that normally defies the point of a template.

More edit: I read through your code, and it needs some work, for example overloading operator[]. In addition, typically, I would make the dimensions part of the template parameters, allowing for the failure of + or += to be caught at compile-time, and allowing the type to be meaningfully stack allocated. Your exception class also needs to derive from std::exception. However, none of those involve compile-time errors, they're just not great code.

Assuming you have a matrix of data called DATA, you can perform partitioning around medoids with estimation of number of clusters (by silhouette analysis) like this:

library(fpc)
maxk <- 20  # arbitrary here, you can set this to whatever you like
estimatedK <- pamk(dist(DATA), krange=1:maxk)$nc

If you just want the button to have different styling while the mouse is pressed you can use the :active pseudo class.

.button:active {
}

If on the other hand you want the style to stay after clicking you will have to use javascript.

The JAX-WS way for basic authentication is

Service s = new Service();
Port port = s.getPort();

BindingProvider prov = (BindingProvider)port;
prov.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "myusername");
prov.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "mypassword");

port.call();

To assign value of a text box whose id is ?textbox? in jQuery please do the following

$("#textbox").val('Blah');

>>> import re
>>> string = "Kl13@£$%[};'\""
>>> pattern = re.compile('\W')
>>> string = re.sub(pattern, '', string)
>>> print string
Kl13

Based on my tests (Win7 64bit, 6GB RAM, Java6), NIO transferFrom is fast only with small files and becomes very slow on larger files. NIO databuffer flip always outperforms standard IO.

• Copying 1000x2MB

  1. NIO (transferFrom) ~2300ms
  2. NIO (direct datababuffer 5000b flip) ~3500ms
  3. Standard IO (buffer 5000b) ~6000ms

• Copying 100x20mb

  1. NIO (direct datababuffer 5000b flip) ~4000ms
  2. NIO (transferFrom) ~5000ms
  3. Standard IO (buffer 5000b) ~6500ms

• Copying 1x1000mb

  1. NIO (direct datababuffer 5000b flip) ~4500s
  2. Standard IO (buffer 5000b) ~7000ms
  3. NIO (transferFrom) ~8000ms

The transferTo() method works on chunks of a file; wasn't intended as a high-level file copy method: How to copy a large file in Windows XP?

I always use this code below for more readable

$('table').append([
'<tr>',
    '<td>My Item 1</td>',
    '<td>My Item 2</td>',
    '<td>My Item 3</td>',
    '<td>My Item 4</td>',
'</tr>'
].join(''));

or if it have tbody

$('table').find('tbody').append([
'<tr>',
    '<td>My Item 1</td>',
    '<td>My Item 2</td>',
    '<td>My Item 3</td>',
    '<td>My Item 4</td>',
'</tr>'
].join(''));

I wrote a little script to manage cloning a new repo and making local branches for all the remote branches.

You can find the latest version here:

#!/bin/bash

# Clones as usual but creates local tracking branches for all remote branches.
# To use, copy this file into the same directory your git binaries are (git, git-flow, git-subtree, etc)

clone_output=$((git clone "$@" ) 2>&1)
retval=$?
echo $clone_output
if [[ $retval != 0 ]] ; then
    exit 1
fi
pushd $(echo $clone_output | head -1 | sed 's/Cloning into .\(.*\).\.\.\./\1/') > /dev/null 2>&1
this_branch=$(git branch | sed 's/^..//')
for i in $(git branch -r | grep -v HEAD); do
  branch=$(echo $i | perl -pe 's/^.*?\///')
  # this doesn't have to be done for each branch, but that's how I did it.
  remote=$(echo $i | sed 's/\/.*//')
  if [[ "$this_branch" != "$branch" ]]; then
      git branch -t $branch $remote/$branch
  fi
done
popd > /dev/null 2>&1

To use it, just copy it into your git bin directory (for me, that’s C:\Program Files (x86)\Git\bin\git-cloneall), then, on the command line:

git cloneall [standard-clone-options] <url>

It clones as usual, but creates local tracking branches for all remote branches.

For fitting y = A + B log x, just fit y against (log x).

>>> x = numpy.array([1, 7, 20, 50, 79])
>>> y = numpy.array([10, 19, 30, 35, 51])
>>> numpy.polyfit(numpy.log(x), y, 1)
array([ 8.46295607,  6.61867463])
# y ˜ 8.46 log(x) + 6.62

For fitting y = Ae^Bx, take the logarithm of both side gives log y = log A + Bx. So fit (log y) against x.

Note that fitting (log y) as if it is linear will emphasize small values of y, causing large deviation for large y. This is because polyfit (linear regression) works by minimizing ?_i (?Y)² = ?_i (Y_i − Y_i)². When Y_i = log y_i, the residues ?Y_i = ?(log y_i) ˜ ?y_i / |y_i|. So even if polyfit makes a very bad decision for large y, the "divide-by-|y|" factor will compensate for it, causing polyfit favors small values.

This could be alleviated by giving each entry a "weight" proportional to y. polyfit supports weighted-least-squares via the w keyword argument.

>>> x = numpy.array([10, 19, 30, 35, 51])
>>> y = numpy.array([1, 7, 20, 50, 79])
>>> numpy.polyfit(x, numpy.log(y), 1)
array([ 0.10502711, -0.40116352])
#    y ˜ exp(-0.401) * exp(0.105 * x) = 0.670 * exp(0.105 * x)
# (^ biased towards small values)
>>> numpy.polyfit(x, numpy.log(y), 1, w=numpy.sqrt(y))
array([ 0.06009446,  1.41648096])
#    y ˜ exp(1.42) * exp(0.0601 * x) = 4.12 * exp(0.0601 * x)
# (^ not so biased)

Note that Excel, LibreOffice and most scientific calculators typically use the unweighted (biased) formula for the exponential regression / trend lines. If you want your results to be compatible with these platforms, do not include the weights even if it provides better results.

Now, if you can use scipy, you could use scipy.optimize.curve_fit to fit any model without transformations.

For y = A + B log x the result is the same as the transformation method:

>>> x = numpy.array([1, 7, 20, 50, 79])
>>> y = numpy.array([10, 19, 30, 35, 51])
>>> scipy.optimize.curve_fit(lambda t,a,b: a+b*numpy.log(t),  x,  y)
(array([ 6.61867467,  8.46295606]), 
 array([[ 28.15948002,  -7.89609542],
        [ -7.89609542,   2.9857172 ]]))
# y ˜ 6.62 + 8.46 log(x)

For y = Ae^Bx, however, we can get a better fit since it computes ?(log y) directly. But we need to provide an initialize guess so curve_fit can reach the desired local minimum.

>>> x = numpy.array([10, 19, 30, 35, 51])
>>> y = numpy.array([1, 7, 20, 50, 79])
>>> scipy.optimize.curve_fit(lambda t,a,b: a*numpy.exp(b*t),  x,  y)
(array([  5.60728326e-21,   9.99993501e-01]),
 array([[  4.14809412e-27,  -1.45078961e-08],
        [ -1.45078961e-08,   5.07411462e+10]]))
# oops, definitely wrong.
>>> scipy.optimize.curve_fit(lambda t,a,b: a*numpy.exp(b*t),  x,  y,  p0=(4, 0.1))
(array([ 4.88003249,  0.05531256]),
 array([[  1.01261314e+01,  -4.31940132e-02],
        [ -4.31940132e-02,   1.91188656e-04]]))
# y ˜ 4.88 exp(0.0553 x). much better.

I have one possibility that doesn't use int at all, and should not raise an exception unless the string does not represent a number

float(number)==float(number)//1

It should work for any kind of string that float accepts, positive, negative, engineering notation...

EDIT: THIS NO LONGER WORKS IN CURRENT ANGULAR-CLI

See answer from @imal hasaranga perera for up-to-date solution

The server in angular-cli comes from the ember-cli project. To configure the server, create an .ember-cli file in the project root. Add your JSON config in there:

{
   "proxy": "https://api.example.com"
}

Restart the server and it will proxy all requests there.

For example, I'm making relative requests in my code to /v1/foo/123, which is being picked up at https://api.example.com/v1/foo/123.

You can also use a flag when you start the server: ng serve --proxy https://api.example.com

Current for angular-cli version: 1.0.0-beta.0

In java you don't check if a key is pressed, instead you listen to KeyEvents. The right way to achieve your goal is to register a KeyEventDispatcher, and implement it to maintain the state of the desired key:

import java.awt.KeyEventDispatcher;
import java.awt.KeyboardFocusManager;
import java.awt.event.KeyEvent;

public class IsKeyPressed {
    private static volatile boolean wPressed = false;
    public static boolean isWPressed() {
        synchronized (IsKeyPressed.class) {
            return wPressed;
        }
    }

    public static void main(String[] args) {
        KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(new KeyEventDispatcher() {

            @Override
            public boolean dispatchKeyEvent(KeyEvent ke) {
                synchronized (IsKeyPressed.class) {
                    switch (ke.getID()) {
                    case KeyEvent.KEY_PRESSED:
                        if (ke.getKeyCode() == KeyEvent.VK_W) {
                            wPressed = true;
                        }
                        break;

                    case KeyEvent.KEY_RELEASED:
                        if (ke.getKeyCode() == KeyEvent.VK_W) {
                            wPressed = false;
                        }
                        break;
                    }
                    return false;
                }
            }
        });
    }
}

Then you can always use:

if (IsKeyPressed.isWPressed()) {
    // do your thing.
}

You can, of course, use same method to implement isPressing("<some key>") with a map of keys and their state wrapped inside IsKeyPressed.

You can do this.
When hovering to the .item1, it will change the .item2 element.

.item1 {
  size:100%;
}

.item1:hover
{
   .item2 {
     border:none;
   }
}

.item2{
  border: solid 1px blue;
}

Some of you might find this useful. Just copy paste it to your page and you will get a sequence in which events are fired in the Chrome console (Ctrl + Shift + I).

$(document).on('pagebeforecreate',function(){console.log('pagebeforecreate');});
$(document).on('pagecreate',function(){console.log('pagecreate');});
$(document).on('pageinit',function(){console.log('pageinit');});
$(document).on('pagebeforehide',function(){console.log('pagebeforehide');});
$(document).on('pagebeforeshow',function(){console.log('pagebeforeshow');});
$(document).on('pageremove',function(){console.log('pageremove');});
$(document).on('pageshow',function(){console.log('pageshow');});
$(document).on('pagehide',function(){console.log('pagehide');});
$(window).load(function () {console.log("window loaded");});
$(window).unload(function () {console.log("window unloaded");});
$(function () {console.log('document ready');});

You are not going see unload in the console as it is fired when the page is being unloaded (when you move away from the page). Use it like this:

$(window).unload(function () { debugger; console.log("window unloaded");});

And you will see what I mean.

In order to copy a file use:

        <plugin>
            <artifactId>maven-resources-plugin</artifactId>
            <version>3.1.0</version>
            <executions>
                <execution>
                    <id>copy-resource-one</id>
                    <phase>install</phase>
                    <goals>
                        <goal>copy-resources</goal>
                    </goals>

                    <configuration>
                        <outputDirectory>${basedir}/destination-folder</outputDirectory>
                        <resources>
                            <resource>
                                <directory>/source-folder</directory>
                                <includes>
                                    <include>file.jar</include>
                                </includes>
                            </resource>
                        </resources>
                    </configuration>
                </execution>
           </executions>
        </plugin>

In order to copy folder with sub-folders use next configuration:

           <configuration>
              <outputDirectory>${basedir}/target-folder</outputDirectory>
              <resources>          
                <resource>
                  <directory>/source-folder</directory>
                  <filtering>true</filtering>
                </resource>
              </resources>              
            </configuration>  

Always use EntityFunctions.TruncateTime() for both x.DateTimeStart and currentDate. such as :

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference).Where(x => EntityFunctions.TruncateTime(x.DateTimeStart) == EntityFunctions.TruncateTime(currentDate));

Redirect iframe in parent window by iframe in the same parent:

window.parent.document.getElementById("content").src = "content.aspx?id=12";

The data is coming back as the string representation of the JSON and you aren't converting it back to a JavaScript object. Set the dataType to just 'json' to have it converted automatically.

You can also replace "-moz-user-select:none" with "-moz-user-select:inherit". This will inherit the style value from any parent style or from the default style if no parent style was defined.

Check out std::stringstream.

Since 2019 you can now use the new functionality called Github package registry.

Basically the process is:

• generate a new personal access token from the github settings
• add repository and token info in your settings.xml

• deploy using

  mvn deploy -Dregistry=https://maven.pkg.github.com/yourusername -Dtoken=yor_token  
  

Another difference between them is the size of the file:

• Mustache.js has 9kb,
• Handlebars.js has 86kb, or 18kb if using precompiled templates.

To see the performance benefits of Handlebars.js we must use precompiled templates.

You may also find a global .gitignore directly at the ~ path if you haven't created it in your folder project. This file is taken into account by all your .git projects.

If it's a CLOB why can't we to_char the column and then search normally ?

Create a table

CREATE TABLE MY_TABLE(Id integer PRIMARY KEY, Name varchar2(20), message clob);

Create few records in this table

INSERT INTO MY_TABLE VALUES(1,'Tom','Hi This is Row one');
INSERT INTO MY_TABLE VALUES(2,'Lucy', 'Hi This is Row two');
INSERT INTO MY_TABLE VALUES(3,'Frank', 'Hi This is Row three');
INSERT INTO MY_TABLE VALUES(4,'Jane', 'Hi This is Row four');
INSERT INTO MY_TABLE VALUES(5,'Robert', 'Hi This is Row five');
COMMIT;

Search in the clob column

SELECT * FROM MY_TABLE where to_char(message) like '%e%';

Results

ID   NAME    MESSAGE   
===============================  
1    Tom     Hi This is Row one         
3    Frank   Hi This is Row three
5    Robert  Hi This is Row five

There should also be a YEAR().

As for comparing, you could compare dates that are the first days of those years and months, or you could convert the year/month pair into a number suitable for comparison (i.e. bigger = later). (Exercise left to the reader. For hints, read about the ISO date format.)

Or you could use multiple comparisons (i.e. years first, then months).

If Chrome DevTools is reporting a 404 for a .map file (maybe jquery-1.10.2.min.map, jquery.min.map or jquery-2.0.3.min.map, but can happen with anything) first thing to know is this is only requested when using the DevTools. Your users will not be hitting this 404.

Now you can fix this or disable the sourcemap functionality.

Fix: get the files

Next, it's an easy fix. Head to http://jquery.com/download/ and click the Download the map file link for your version, and you'll want the uncompressed file downloaded as well.

Having the map file in place allows you do debug your minified jQuery via the original sources, which will save a lot of time and frustration if you don't like dealing with variable names like a and c.

More about sourcemaps here: An Introduction to JavaScript Source Maps

Dodge: disable sourcemaps

Instead of getting the files, you can alternatively disable JavaScript source maps completely for now, in your settings. This is a fine choice if you never plan on debugging JavaScript on this page. Use the cog icon in the bottom right of the DevTools, to open settings, then:

That depends on the nature of the information you want to return.

If it is a single integer value, you can use the return statement

 create proc myproc
 as 
 begin
     return 1
 end
 go
 declare @i int
 exec @i = myproc

If you have a non integer value, or a number of scalar values, you can use output parameters

create proc myproc
  @a int output,
  @b varchar(50) output
as
begin
  select @a = 1, @b='hello'
end
go
declare @i int, @j varchar(50)
exec myproc @i output, @j output

If you want to return a dataset, you can use insert exec

create proc myproc
as 
begin
     select name from sysobjects
end
go

declare @t table (name varchar(100))
insert @t (name)
exec myproc

You can even return a cursor but that's just horrid so I shan't give an example :)

This will work for generating a number 1 - 10. Make sure you import Random at the top of your code.

import java.util.Random;

If you want to test it out try something like this.

Random rn = new Random();

for(int i =0; i < 100; i++)
{
    int answer = rn.nextInt(10) + 1;
    System.out.println(answer);
}

Also if you change the number in parenthesis it will create a random number from 0 to that number -1 (unless you add one of course like you have then it will be from 1 to the number you've entered).

This would have worked too. The first quoted pair are interpreted as a window title name in the start command.

start "" "myfile.txt"
start "" "myshortcut.lnk"

You can also face this situation if your upstream server uses a domain name, and its IP address changes (e.g.: your upstream points to an AWS Elastic Load Balancer)

The problem is that nginx will resolve the IP address once, and keep it cached for subsequent requests until the configuration is reloaded.

You can tell nginx to use a name server to re-resolve the domain once the cached entry expires:

location /mylocation {
    # use google dns to resolve host after IP cached expires
    resolver 8.8.8.8;
    set $upstream_endpoint http://your.backend.server/;
    proxy_pass $upstream_endpoint;
}

The docs on proxy_pass explain why this trick works:

Parameter value can contain variables. In this case, if an address is specified as a domain name, the name is searched among the described server groups, and, if not found, is determined using a resolver.

Kudos to "Nginx with dynamic upstreams" (tenzer.dk) for the detailed explanation, which also contains some relevant information on a caveat of this approach regarding forwarded URIs.

you can also print the data onto your HTML/JSP document. like:-

If you have a very limited number of levels, you could try converting y into factor and change its levels.

> xy <- data.frame(x = c(1, 2, 4), y = c(1, 4, 5))
> xy$w <- as.factor(xy$y)
> levels(xy$w) <- c("good", "fair", "bad")
> xy
  x y    w
1 1 1 good
2 2 4 fair
3 4 5  bad

For the future googlers: use RingtoneManager.getActualDefaultRingtoneUri() instead of RingtoneManager.getDefaultUri(). According to its name, it would return the actual uri, so you can freely use it. From documentation of getActualDefaultRingtoneUri():

Gets the current default sound's Uri. This will give the actual sound Uri, instead of using this, most clients can use DEFAULT_RINGTONE_URI.

Meanwhile getDefaultUri() says this:

Returns the Uri for the default ringtone of a particular type. Rather than returning the actual ringtone's sound Uri, this will return the symbolic Uri which will resolved to the actual sound when played.

Install sshpass, then launch the command:

sshpass -p "yourpassword" ssh -o StrictHostKeyChecking=no yourusername@hostname

$(window).keypress(function(event) {
    if (!(event.which == 115 && event.ctrlKey) && !(event.which == 19)) return true;
    alert("Ctrl-S pressed");
    event.preventDefault();
    return false;
});

Key codes can differ between browsers, so you may need to check for more than just 115.

I configure a servlet in web.ml , again i configured same servlet using annotations in servlet class. I removed annotation based configuration then server started properly.

I also faced the same problem it was because another mysql service was running and in parallel mysql in xampp i was trying to run. So you may check that out if other solutions don't work out. You can stop that by the following command:

sudo service mysql stop

In chart.js 2.1.6, I did something like this (in typescript):

  let that = this;
  options = {
    legend: {
      display: false,
      responsive: false
    },
    tooltips: {
      callbacks: {
        label: function(tooltipItem, data) {
          let account: Account = that.accounts[tooltipItem.index];
          return account.accountNumber+":"+account.balance+"€";
        }
      }
    }
  }

The best option I found is a plugin called jMenu.

Screenshot:

In practice, there are two differences:

1. printing (eg with cout in C++ or printf in C): unsigned integer bit representation is interpreted as a nonnegative integer by print functions.
2. ordering: the ordering depends on signed or unsigned specifications.

this code can identify the integer using ordering criterion:

char a = 0;
a--;
if (0 < a)
    printf("unsigned");
else
    printf("signed");

char is considered signed in some compilers and unsigned in other compilers. The code above determines which one is considered in a compiler, using the ordering criterion. If a is unsigned, after a--, it will be greater than 0, but if it is signed it will be less than zero. But in both cases, the bit representation of a is the same. That is, in both cases a-- does the same change to the bit representation.

Moore's answer doesn't work, and the page here:

Specifying the Selection Color, Content Alignment, and Background Color for items in a ListBox

explains why it cannot work.

If your listview only contains basic text, the simplest way to solve the problem is by using transparent brushes.

<Window.Resources>
  <Style TargetType="{x:Type ListViewItem}">
    <Style.Resources>
      <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="#00000000"/>
      <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="#00000000"/>
    </Style.Resources>
  </Style>
</Window.Resources>

This will produce undesirable results if the listview's cells are holding controls such as comboboxes, since it also changes their color. To solve this problem, you must redefine the control's template.

  <Window.Resources>
    <Style TargetType="{x:Type ListViewItem}">
      <Setter Property="Template">
        <Setter.Value>
          <ControlTemplate TargetType="{x:Type ListViewItem}">
            <Border SnapsToDevicePixels="True" 
                    x:Name="Bd" 
                    Background="{TemplateBinding Background}" 
                    BorderBrush="{TemplateBinding BorderBrush}" 
                    BorderThickness="{TemplateBinding BorderThickness}" 
                    Padding="{TemplateBinding Padding}">
              <GridViewRowPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" 
                                    VerticalAlignment="{TemplateBinding VerticalContentAlignment}" 
                                    Columns="{TemplateBinding GridView.ColumnCollection}" 
                                    Content="{TemplateBinding Content}"/>
            </Border>
            <ControlTemplate.Triggers>
              <Trigger Property="IsEnabled" 
                       Value="False">
                <Setter Property="Foreground" 
                        Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
              </Trigger>
            </ControlTemplate.Triggers>
          </ControlTemplate>
        </Setter.Value>

Both algorithms (AES and twofish) are considered very secure. This has been widely covered in other answers.

However, since AES is much widely used now in 2016, it has been specifically hardware-accelerated in several platforms such as ARM and x86. While not significantly faster than twofish before hardware acceleration, AES is now much faster thanks to the dedicated CPU instructions.

%time% should work, provided enough time has elapsed between calls:

This is how you can use it in your activity:

CustomImageVIew mImageView = (CustomImageVIew)findViewById(R.id.customImageVIew1);
mImage.setBitmap(your bitmap);

And layout:

<your.package.name.CustomImageVIew
        android:id="@+id/customImageVIew1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_marginBottom="15dp"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:layout_marginTop="15dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" 
        android:scaleType="matrix"/> // important

In Simple,e.printStackTrace() is not good practice,because it just prints out the stack trace to standard error. Because of this you can't really control where this output goes.

Interactively, you can display it with

help(my_func)

Or from code you can retrieve it with

my_func.__doc__

gcc can use an assembly file as input, and invoke the assembler as needed. There is a subtlety, though:

• If the file name ends with ".s" (lowercase 's'), then gcc calls the assembler.
• If the file name ends with ".S" (uppercase 'S'), then gcc applies the C preprocessor on the source file (i.e. it recognizes directives such as #if and replaces macros), and then calls the assembler on the result.

So, on a general basis, you want to do things like this:

gcc -S file.c -o file.s
gcc -c file.s

Well... I had a similar problem... I want an incremental / step search with RegExp (eg: start search... do some processing... continue search until last match)

After lots of internet search... like always (this is turning an habit now) I end up in StackOverflow and found the answer...

Whats is not referred and matters to mention is "lastIndex" I now understand why the RegExp object implements the "lastIndex" property

    function gotofirst(){
        window.location = "firstServelet.java";
}
    function gotosecond(){
        window.location = "secondServelet.java";
}

<form action="FirstServlet" method="Post">
    Last Name: <input type="text" name="lastName" size="20">
    <br><br>
    <input type="submit" onclick="gotofirst()" value="FirstServlet">
    <input type="submit" onclick="gotosecond()" value="SecondServlet">
</form>

You could use a projection with a statement lambda, but the original foreach loop is more readable and is editing the list in place rather than creating a new list.

var result = list.Select(i => 
   { 
      if (i.Name == "height") i.Value = 30;
      return i; 
   }).ToList();

Extension Method

public static IEnumerable<MyClass> SetHeights(
    this IEnumerable<MyClass> source, int value)
{
    foreach (var item in source)
    {
       if (item.Name == "height")
       {
           item.Value = value;
       }

       yield return item;
    } 
}

var result = list.SetHeights(30).ToList();

I have used these convenience methods before:

- (CGRect)getScreenFrameForCurrentOrientation {
    return [self getScreenFrameForOrientation:[UIApplication sharedApplication].statusBarOrientation];
}

- (CGRect)getScreenFrameForOrientation:(UIInterfaceOrientation)orientation {

    CGRect fullScreenRect = [[UIScreen mainScreen] bounds];

    // implicitly in Portrait orientation.
    if (UIInterfaceOrientationIsLandscape(orientation)) {
      CGRect temp = CGRectZero;
      temp.size.width = fullScreenRect.size.height;
      temp.size.height = fullScreenRect.size.width;
      fullScreenRect = temp;
    }

    if (![[UIApplication sharedApplication] statusBarHidden]) {
      CGFloat statusBarHeight = 20; // Needs a better solution, FYI statusBarFrame reports wrong in some cases..
      fullScreenRect.size.height -= statusBarHeight;
    }

    return fullScreenRect;
} 

Since Spring 2.5 there's a very easy (and elegant) way to achieve that.

You can just change the params proxyMode and value of the @Scope annotation.

With this trick you can avoid to write extra code or to inject the ApplicationContext every time that you need a prototype inside a singleton bean.

Example:

@Service 
@Scope(value="prototype", proxyMode=ScopedProxyMode.TARGET_CLASS)  
public class LoginAction {}

With the config above LoginAction (inside HomeController) is always a prototype even though the controller is a singleton.

I really appreciate some of the answers above, following @hadley and @Dirk that suggest closing R and issuing source and using command line I come up with a solution that worked very well for me. I had to deal with hundreds of mass spectras, each occupies around 20 Mb of memory so I used two R scripts, as follows:

First a wrapper:

#!/usr/bin/Rscript --vanilla --default-packages=utils

for(l in 1:length(fdir)) {

   for(k in 1:length(fds)) {
     system(paste("Rscript runConsensus.r", l, k))
   }
}

with this script I basically control what my main script do runConsensus.r, and I write the data answer for the output. With this, each time the wrapper calls the script it seems the R is reopened and the memory is freed.

Hope it helps.

Enough standards, let's look at an implementation :-)

Local variable

Standards: undefined behavior.

Implementation: the program allocates stack space, and never moves anything to that address, so whatever was there previously is used.

#include <stdio.h>
int main() {
    int i;

From our knowledge of x86-64 calling conventions:

• %rdi is the first printf argument, thus the string "%d\n" at address 0x4005e4

• %rsi is the second printf argument, thus i.

  It comes from -0x4(%rbp), which is the first 4-byte local variable.

  At this point, rbp is in the first page of the stack has been allocated by the kernel, so to understand that value we would to look into the kernel code and find out what it sets that to.

  TODO does the kernel set that memory to something before reusing it for other processes when a process dies? If not, the new process would be able to read the memory of other finished programs, leaking data. See: Are uninitialized values ever a security risk?

We can then also play with our own stack modifications and write fun things like:

#include <assert.h>

int f() {
    int i = 13;
    return i;
}

int g() {
    int i;
    return i;
}

int main() {
    f();
    assert(g() == 13);
}

which says 0x601044 is right in the middle of the .bss section, which starts at 0x601040 and is 8 bytes long.

The ELF standard then guarantees that the section named .bss is completely filled with of zeros:

.bss This section holds uninitialized data that contribute to the program’s memory image. By definition, the system initializes the data with zeros when the program begins to run. The section occu- pies no file space, as indicated by the section type, SHT_NOBITS.

Furthermore, the type SHT_NOBITS is efficient and occupies no space on the executable file:

sh_size This member gives the section’s size in bytes. Unless the sec- tion type is SHT_NOBITS , the section occupies sh_size bytes in the file. A section of type SHT_NOBITS may have a non-zero size, but it occupies no space in the file.

Then it is up to the Linux kernel to zero out that memory region when loading the program into memory when it gets started.

List<Integer> list1 = new ArrayList<Integer>(Arrays.asList(ia));  //copy

In this case, list1 is of type ArrayList.

List<Integer> list2 = Arrays.asList(ia);

Here, the list is returned as a List view, meaning it has only the methods attached to that interface. Hence why some methods are not allowed on list2.

ArrayList<Integer> list1 = new ArrayList<Integer>(Arrays.asList(ia));

Here, you ARE creating a new ArrayList. You're simply passing it a value in the constructor. This is not an example of casting. In casting, it might look more like this:

ArrayList list1 = (ArrayList)Arrays.asList(ia);

function IsNumeric(val) {
    return Number(parseFloat(val)) === val;
}

width: '100%' and alignSelf: 'stretch' didn't work for me. Dimensions didn't suite my task cause I needed to operate on a deeply nested view. Here's what worked for me, if I rewrite your code. I just added some more Views and used flex properties to achieve the needed layout:

    {/* some rows here */}
    <Text style={styles.welcome}>

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.

I think this is the simplest way for anyone else stumbling on this post given the late response:

>>> string = 'This is a string, with words!'
>>> string.split()
['This', 'is', 'a', 'string,', 'with', 'words!']

From find manual:

NON-BUGS         

   Operator precedence surprises
   The command find . -name afile -o -name bfile -print will never print
   afile because this is actually equivalent to find . -name afile -o \(
   -name bfile -a -print \).  Remember that the precedence of -a is
   higher than that of -o and when there is no operator specified
   between tests, -a is assumed.

   “paths must precede expression” error message
   $ find . -name *.c -print
   find: paths must precede expression
   Usage: find [-H] [-L] [-P] [-Olevel] [-D ... [path...] [expression]

   This happens because *.c has been expanded by the shell resulting in
   find actually receiving a command line like this:
   find . -name frcode.c locate.c word_io.c -print
   That command is of course not going to work.  Instead of doing things
   this way, you should enclose the pattern in quotes or escape the
   wildcard:
   $ find . -name '*.c' -print
   $ find . -name \*.c -print

I not be able to find squid number in sonar 5.6, with this annotation also works:

You can convert a numpy array to list and get its index .

for example:

tmp = [1,2,3,4,5] #python list
a = numpy.array(tmp) #numpy array
i = list(a).index(2) # i will return index of 2, which is 1

this is just what you wanted.

Combining the solutions proposed by Daren and Thanos we have a good .vimrc file.

I thought I'd chip in a couple of notes.

1. < div > can be disabled in IE8/9. I assume this is "incorrect", and it threw me off
2. Don't use .removeProp(), as it has a permanent effect on the element. Use .prop("disabled", false) instead
3. $("#myDiv").filter("input,textarea,select,button").prop("disabled", true) is more explicit and will catch some form elements you would miss with :input

The only way that worked for me is presenting dummy modal view controller.

UIViewController* dummyVC = [[UIViewController alloc] init];
dummyVC.view = [[UIView alloc] init];
[self presentModalViewController:dummyVC animated:NO];
[self dismissModalViewControllerAnimated:NO];

Your VC will be asked for updated interface orientations when modal view controller is dismissed.

Curious thing is that UINavigationController does exactly this when pushing/popping child view controllers with different supported interface orientations (tested on iOS 6.1, 7.0).

The 2 and 3 in the question posed are decidedly magic-numberish. The 'correct' answer will depend on whether the interviewer was trying to get at your grasp of boolean logic (and I don't think pdox's answer could be bested in this respect) or your understanding of architectural issues.

I'd be inclined to go with a map-reduce solution that will accept any sort of list with any arbitrary condition.

The element that you posted looks like it's just copy-pasted from the Google Maps embed feature.

If you'd like to drop markers for the locations that you have, you'll need to write some JavaScript to do so. I'm learning how to do this as well.

Check out the following: https://developers.google.com/maps/documentation/javascript/overlays

It has several examples and code samples that can be easily re-used and adapted to fit your current problem.

CTRL + H, then select regex (*) and write \n

Shorter version: CTRL+H ALT+R \n

I had a similar problems, till I got it working. Below is the full listing of the integration:

1. Generate public/private keys pair: ssh-keygen -t rsa

2. Copy the public key (~/.ssh/id_rsa.pub) and paste it in Bitbucket SSH keys, in user’s account management console:

3. Copy the private key (~/.ssh/id_rsa) to new user (or even existing one) with private key credentials, in this case, username will not make a difference, so username can be anything:

4. run this command to test if you can get access to Bitbucket account: ssh -T [email protected]

5. OPTIONAL: Now, you can use your git to to copy repo to your desk without passwjord git clone [email protected]:username/repo_name.git

6. Now you can enable Bitbucket hooks for Jenkins push notifications and automatic builds, you will do that in 2 steps:

   1. Add an authentication token inside the job/project you configure, it can be anything:

   2. In Bitbucket hooks: choose jenkins hooks, and fill the fields as below:

Where:

**End point**: username:usertoken@jenkins_domain_or_ip
**Project name**: is the name of job you created on Jenkins
**Token**: Is the authorization token you added in the above steps in your Jenkins' job/project 

Recommendation: I usually add the usertoken as the authorization Token (in both Jenkins Auth Token job configuration and Bitbucket hooks), making them one variable to ease things on myself.

IP can be any LAN or WAN IP address. But you'll want to set your firewall connection allow it.

Device connection with webserver pc can be by LAN or WAN (i.e by wifi, connectify, adhoc, cable, mypublic wifi etc)

You should follow these steps:

1. Go to the control panel
2. Inbound rules > new rules
3. Click port > next > specific local port > enter 8080 > next > allow the connection>
4. Next > tick all (domain, private, public) > specify any name
5. Now you can access your localhost by any device (laptop, mobile, desktop, etc).
6. Enter ip address in browser url as 123.23.xx.xx:8080 to access localhost by any device.

This IP will be of that device which has the web server.

here is what i did. wanted to make sure i could click any of the children in my datepicker without closing it.

$('html').click(function(e){
    if (e.target.id == 'menu_content' || $(e.target).parents('#menu_content').length > 0) {
        // clicked menu content or children
    } else {
        // didnt click menu content
    }
});

my actual code:

$('html').click(function(e){
    if (e.target.id != 'datepicker'
        && $(e.target).parents('#datepicker').length == 0
        && !$(e.target).hasClass('datepicker')
    ) {
        $('#datepicker').remove();
    }
});

Try {{model?.person.name}} this should wait for model to not be undefined and then render.

Angular 2 refers to this ?. syntax as the Elvis operator. Reference to it in the documentation is hard to find so here is a copy of it in case they change/move it:

The Elvis Operator ( ?. ) and null property paths

The Angular “Elvis” operator ( ?. ) is a fluent and convenient way to guard against null and undefined values in property paths. Here it is, protecting against a view render failure if the currentHero is null.

The current hero's name is {{currentHero?.firstName}}

Let’s elaborate on the problem and this particular solution.

What happens when the following data bound title property is null?

The title is {{ title }}

The view still renders but the displayed value is blank; we see only "The title is" with nothing after it. That is reasonable behavior. At least the app doesn't crash.

Suppose the template expression involves a property path as in this next example where we’re displaying the firstName of a null hero.

The null hero's name is {{nullHero.firstName}}

JavaScript throws a null reference error and so does Angular:

TypeError: Cannot read property 'firstName' of null in [null]

Worse, the entire view disappears.

We could claim that this is reasonable behavior if we believed that the hero property must never be null. If it must never be null and yet it is null, we've made a programming error that should be caught and fixed. Throwing an exception is the right thing to do.

On the other hand, null values in the property path may be OK from time to time, especially when we know the data will arrive eventually.

While we wait for data, the view should render without complaint and the null property path should display as blank just as the title property does.

Unfortunately, our app crashes when the currentHero is null.

We could code around that problem with NgIf

<!--No hero, div not displayed, no error --> <div *ngIf="nullHero">The null hero's name is {{nullHero.firstName}}</div>

Or we could try to chain parts of the property path with &&, knowing that the expression bails out when it encounters the first null.

The null hero's name is {{nullHero && nullHero.firstName}}

These approaches have merit but they can be cumbersome, especially if the property path is long. Imagine guarding against a null somewhere in a long property path such as a.b.c.d.

The Angular “Elvis” operator ( ?. ) is a more fluent and convenient way to guard against nulls in property paths. The expression bails out when it hits the first null value. The display is blank but the app keeps rolling and there are no errors.

<!-- No hero, no problem! --> The null hero's name is {{nullHero?.firstName}}

It works perfectly with long property paths too:

a?.b?.c?.d

Well, this is probably frowned upon but you can make a 1px transparent image, then size it as needed in between text.

Some text <img src="spacer.png" height="1px" width="10px"> Some more text

I've run into this issue when one or two spaces just wasn't enough for my design sensibilities.

I couldn't get the compiler (x64 version) to use the sysroot until I added SET(CMAKE_SYSROOT $ENV{HOME}/raspberrypi/rootfs) to pi.cmake.

    request.httpMethod = "POST" //set http method as POST

    do {
        request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) // pass dictionary to nsdata object and set it as request body
    } catch let error {
        print(error.localizedDescription)
    }

    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    //create dataTask using the session object to send data to the server
    let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in

        guard error == nil else {
            return
        }

        guard let data = data else {
            return
        }

        do {
            //create json object from data
            if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
                print(json)
                // handle json...
            }
        } catch let error {
            print(error.localizedDescription)
        }
    })
    task.resume()
}

One thing which seems like no one else mentioned: let's say you have a vertical LinearLayout, so in order for the weights in layout/element/view inside it to work 100% properly - all of them must have layout_height property (which must exist in your xml file) set to 0dp. Seems like any other value would mess things up in some cases.

You can also set headers for the entire session:

TOKEN = 'abcd0123'
HEADERS = {'Authorization': 'token {}'.format(TOKEN)}

with requests.Session() as s:

    s.headers.update(HEADERS)
    resp = s.get('http://example.com/')

You want something more like this:

SELECT TableA.*, TableB.*, TableC.*, TableD.*
FROM TableA
    JOIN TableB
        ON TableB.aID = TableA.aID
    JOIN TableC
        ON TableC.cID = TableB.cID
    JOIN TableD
        ON TableD.dID = TableA.dID
WHERE DATE(TableC.date)=date(now()) 

In your example, you are not actually including TableD. All you have to do is perform another join just like you have done before.

A note: you will notice that I removed many of your parentheses, as they really are not necessary in most of the cases you had them, and only add confusion when trying to read the code. Proper nesting is the best way to make your code readable and separated out.

SMTP implementations MUST take care to preserve the case of mailbox local-parts. In particular, for some hosts, the user "smith" is different from the user "Smith".

Mailbox domains follow normal DNS rules and are hence not case sensitive

Try this, This will show all commits recorded in git for a period of time

git reflog

Find the commit you want with

git log HEAD@{3}

or

git log -p HEAD@{3}    

Then check it out if it's the right one:

git checkout HEAD@{3}

This will create a detached head for that commit. Add and commit any changes if needed

git status 
git add
git commit -m "temp_work" 

Now if want to restore commit back to a branch lets say master you will need to name this branch switch to master then merge to master.

git branch temp
git checkout master
git merge temp

Here's also a link specifically for reflog on a Git tutorial site: Atlassian Git Tutorial

In some cases it might make more sense to process each selected item one at a time.

In other words, make a separate server call for each selected item passing the value of the selected item. In some cases the list will need to be processed as a whole, but in some not.

I needed to process a list of selected people and then have the results of the query show up on an existing page beneath the existing data for that person. I initially though of passing the whole list to the server, parsing the list, then passing back the data for all of the patients. I would have then needed to parse the returning data and insert it into the page in each of the appropriate places. Sending the request for the data one person at a time turned out to be much easier. Javascript for getting the selected items is described here: check if checkbox is checked javascript and jQuery for the same is described here: How to check whether a checkbox is checked in jQuery?.

In addition to the accepted answer, I want to give you an example!

For instance, we all use

System.Console.WriteLine()

But Where is the code for System.Console.WriteLine!?
which is the code that actually puts the text on the console?

If you look at the first page of the documentation for the Console class, you‘ll see near the top the following: Assembly: mscorlib (in mscorlib.dll) This indicates that the code for the Console class is located in an assem-bly named mscorlib. An assembly can consist of multiple files, but in this case it‘s only one file, which is the dynamic link library mscorlib.dll.

The mscorlib.dll file is very important in .NET, It is the main DLL for class libraries in .NET, and it contains all the basic .NET classes and structures.

if you know C or C++, generally you need a #include directive at the top that references a header file. The include file provides function prototypes to the compiler. on the contrast The C# compiler does not need header files. During compilation, the C# compiler access the mscorlib.dll file directly and obtains information from metadata in that file concerning all the classes and other types defined therein.

The C# compiler is able to establish that mscorlib.dll does indeed contain a class named Console in a namespace named System with a method named WriteLine that accepts a single argument of type string.

The C# compiler can determine that the WriteLine call is valid, and the compiler establishes a reference to the mscorlib assembly in the executable.

by default The C# compiler will access mscorlib.dll, but for other DLLs, you‘ll need to tell the compiler the assembly in which the classes are located. These are known as references.

I hope that it's clear now!

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

I'm using Android Studio (JetBrains IntelliJ IDEA) on Mac OS and my problem was that ^M started to show up in some files in my pull request on GitHub. What worked for me was changing line separator for a file.

Open the desired file in the editor go to File go to Line Separators then choose the best option for you (for me it was LF - Unix and OS X(\n) )

According to the next article this problem is a result of confused line endings between operating systems: http://jonathonstaff.com/blog/issues-with-line-endings/

And more information you can find here: https://www.jetbrains.com/help/idea/configuring-line-separators.html#d84378e48

One very simple way to make a method asynchronous is to use Task.Yield() method. As MSDN states:

You can use await Task.Yield(); in an asynchronous method to force the method to complete asynchronously.

Insert it at beginning of your method and it will then return immediately to the caller and complete the rest of the method on another thread.

private async Task<DateTime> CountToAsync(int num = 1000)
{
    await Task.Yield();
    for (int i = 0; i < num; i++)
    {
        Console.WriteLine("#{0}", i);
    }
    return DateTime.Now;
}

This one seems to work on both Windows and Linux* (from this question):

def beep():
    print("\a")

beep()

In Windows, can put at the end:

import winsound
winsound.Beep(500, 1000)

where 500 is the frequency in Herz
      1000 is the duration in miliseconds

To work on Linux, you may need to do the following (from QO's comment):

• in a terminal, type 'cd /etc/modprobe.d' then 'gksudo gedit blacklist.conf'
• comment the line that says 'blacklist pcspkr', then reboot
• check also that the terminal preferences has the 'Terminal Bell' checked.

Try something like:-

ALTER TABLE table_name ADD  CONSTRAINT [DF_table_name_Created] 
DEFAULT (getdate()) FOR [created_at];

replacing table_name with the name of your table.

This issue occur when you migrate your android project build in windows to any unix operating system (Linux). So you need to run the below command in your project directory to convert dos Line Break to Unix Line Break.

find . -type f -print0 | xargs -0 dos2unix

If you dont have dos2unix installed. Install it using

In CentOs/Fedora

yum install dos2unix

In Ubuntu and other distributions

sudo apt install dos2unix

With the potential for badly behaved transparent proxies in between you and the client, the only way to totally guarantee that images will not be cached is to give them a unique uri, something like tagging a timestamp on as a query string or as part of the path.

If that timestamp corresponds to the last update time of the image, then you can cache when you need to and serve the new image at just the right time.

Seeing the answers I have nothing else to add but one more thing:

in your test.html file you have written

link rel="stylesheet" type="css/text" href="test.css"/

see where you have written

type="css/text"

there you need to change into

type="text/css"

so it will look like that

link rel="stylesheet" type="text/css" href="test.css"/

and in this case the CSS file will be linked to HTML file

in my opinion strstr() is better than strpos(). because strstr() is compatible with both PHP 4 AND PHP 5. but strpos() is only compatible with PHP 5. please note that part of servers have no PHP 5

Looks like different approaches for different version. I am using Flutter v1.17.1 and the below works for me.

onTap: () {
    FocusScopeNode currentFocus = FocusScope.of(context);
    if (!currentFocus.hasPrimaryFocus && currentFocus.focusedChild != null) {
       currentFocus.focusedChild.unfocus();
    }
}

Code for Future Date only with disable today's date.

 var d = new Date();
         $("#delivdate").datepicker({
         showOn: "button",
         buttonImage: base_url+"images/cal.png",
         minDate:new Date(d.setDate(d.getDate() + 1)),
         buttonImageOnly: true
        });
         $('.ui-datepicker-trigger').attr('title',''); 

I used to encounter this is my development, what I do is wrap my solution in a function to make it reusable in my environment, like this:

const sumArrayOfObject =(array, prop)=>array.reduce((sum, n)=>{return sum + n[prop]}, 0)

Useful commands to work in daily life:

git checkout -b "branchname" ->  creates new branch
git branch                   ->  lists all branches
git checkout "branchname"    ->  switches to your branch
git push origin "branchname" ->  Pushes to your branch
git add */filename           -> Stages *(All files) or by given file name
git commit -m "commit message" -> Commits staged files
git push                     -> Pushes to your current branch

If you want to merge to dev from feature branch, First check out dev branch with command "git branch dev/develop" Then enter merge commadn "git merge featurebranchname"

Use the S_ISDIRmacro:

int isDirectory(const char *path) {
   struct stat statbuf;
   if (stat(path, &statbuf) != 0)
       return 0;
   return S_ISDIR(statbuf.st_mode);
}

memset(array, 0, sizeof(int [n][n]));

When the compiler compiles the class User and gets to the MyMessageBox line, MyMessageBox has not yet been defined. The compiler has no idea MyMessageBox exists, so cannot understand the meaning of your class member.

You need to make sure MyMessageBox is defined before you use it as a member. This is solved by reversing the definition order. However, you have a cyclic dependency: if you move MyMessageBox above User, then in the definition of MyMessageBox the name User won't be defined!

What you can do is forward declare User; that is, declare it but don't define it. During compilation, a type that is declared but not defined is called an incomplete type. Consider the simpler example:

struct foo; // foo is *declared* to be a struct, but that struct is not yet defined

struct bar
{
    // this is okay, it's just a pointer;
    // we can point to something without knowing how that something is defined
    foo* fp; 

    // likewise, we can form a reference to it
    void some_func(foo& fr);

    // but this would be an error, as before, because it requires a definition
    /* foo fooMember; */
};

struct foo // okay, now define foo!
{
    int fooInt;
    double fooDouble;
};

void bar::some_func(foo& fr)
{
    // now that foo is defined, we can read that reference:
    fr.fooInt = 111605;
    fr.foDouble = 123.456;
}

By forward declaring User, MyMessageBox can still form a pointer or reference to it:

class User; // let the compiler know such a class will be defined

class MyMessageBox
{
public:
    // this is ok, no definitions needed yet for User (or Message)
    void sendMessage(Message *msg, User *recvr); 

    Message receiveMessage();
    vector<Message>* dataMessageList;
};

class User
{
public:
    // also ok, since it's now defined
    MyMessageBox dataMsgBox;
};

You cannot do this the other way around: as mentioned, a class member needs to have a definition. (The reason is that the compiler needs to know how much memory User takes up, and to know that it needs to know the size of its members.) If you were to say:

class MyMessageBox;

class User
{
public:
    // size not available! it's an incomplete type
    MyMessageBox dataMsgBox;
};

It wouldn't work, since it doesn't know the size yet.

On a side note, this function:

 void sendMessage(Message *msg, User *recvr);

Probably shouldn't take either of those by pointer. You can't send a message without a message, nor can you send a message without a user to send it to. And both of those situations are expressible by passing null as an argument to either parameter (null is a perfectly valid pointer value!)

Rather, use a reference (possibly const):

 void sendMessage(const Message& msg, User& recvr);

This just works:

$body = @{
 "UserSessionId"="12345678"
 "OptionalEmail"="[email protected]"
} | ConvertTo-Json

$header = @{
 "Accept"="application/json"
 "connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed"
 "Content-Type"="application/json"
} 

Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML

There are a lot of options and tools. If you just want a list of listening ports and their owner processes try.

I don't think there is a way to tell which program to use from just the .db extension. It could even be an encrypted database which can't be opened. You can MS Access, or a sqlite manager.

Edit: Try to rename the file to .txt and open it with a text editor. The first couple of words in the file could tell you the DB Type.

If it is a SQLite database, it will start with "SQLite format 3"

you have to change permission on the mentioned path.

You can do it by using LINQ-expression.

  public static List<int> StringToAscii(string value)
  {
        if (string.IsNullOrEmpty(value))
            throw new ArgumentException("Value cannot be null or empty.", nameof(value));

        return value.Select(System.Convert.ToInt32).ToList();
  } 

As already stated, you cannot decrypt MD5 without attempting something like brute force hacking which is extremely resource intensive, not practical, and unethical.

However you could use something like this to encrypt / decrypt passwords/etc safely:

$input = "SmackFactory";

$encrypted = encryptIt( $input );
$decrypted = decryptIt( $encrypted );

echo $encrypted . '<br />' . $decrypted;

function encryptIt( $q ) {
    $cryptKey  = 'qJB0rGtIn5UB1xG03efyCp';
    $qEncoded      = base64_encode( mcrypt_encrypt( MCRYPT_RIJNDAEL_256, md5( $cryptKey ), $q, MCRYPT_MODE_CBC, md5( md5( $cryptKey ) ) ) );
    return( $qEncoded );
}

function decryptIt( $q ) {
    $cryptKey  = 'qJB0rGtIn5UB1xG03efyCp';
    $qDecoded      = rtrim( mcrypt_decrypt( MCRYPT_RIJNDAEL_256, md5( $cryptKey ), base64_decode( $q ), MCRYPT_MODE_CBC, md5( md5( $cryptKey ) ) ), "\0");
    return( $qDecoded );
}

Using a encypted method with a salt would be even safer, but this would be a good next step past just using a MD5 hash.

If You have no access to plugin for instance outside of controller You can get params from servicelocator like this

//from POST
$foo = $this->serviceLocator->get('request')->getPost('foo'); 
//from GET
$foo = $this->serviceLocator->get('request')->getQuery()->foo;
//from route
$foo = $this->serviceLocator->get('application')->getMvcEvent()->getRouteMatch()->getParam('foo');

If you are using BookId as an combined primary key, then remember to change your interface from:

public interface QueuedBookRepo extends JpaRepository<QueuedBook, Long> {

to:

public interface QueuedBookRepo extends JpaRepository<QueuedBook, BookId> {

And change the annotation @Embedded to @EmbeddedId, in your QueuedBook class like this:

public class QueuedBook implements Serializable {

@EmbeddedId
@NotNull
private BookId bookId;

2. Change this line:

    distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip
   

with

        distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip

3. Go to build.gradle (Project: your_app_name)

4. Change this line

    classpath 'com.android.tools.build:gradle:XXX'
   

to this

     classpath 'com.android.tools.build:gradle:2.0.0-alpha3'

or

     classpath 'com.android.tools.build:gradle:1.5.0'

5. Don't click Sync Now
6. From menu choose File -> Invalidate Caches/Restart...
7. Choose first option: Invalidate and Restart

Android Studio would restart. After this, it should work normally

Hope it help

Drawing heavily from a number of other answers here, I've ended up with the following (git 2.13 and above only, I believe), which should work on any UNIX-like shell:

git for-each-ref --shell --format='ref=%(if:equals=[gone])%(upstream:track)%(then)%(refname)%(end)' refs/heads | while read entry; do eval "$entry"; [ ! -z "$ref" ] && git update-ref -d "$ref" && echo "deleted $ref"; done

This notably uses for-each-ref instead of branch (as branch is a "porcelain" command designed for human-readable output, not machine-processing) and uses its --shell argument to get properly escaped output (this allows us to not worry about any character in the ref name).

The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.

The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.

Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.

For people looking this up now:

It seems that now setting the User-Agent header is allowed since Firefox 43. See https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name for the current list of forbidden headers.

You need to make sure that you add forward slash before your link to socket.io:

<script src="/socket.io/socket.io.js"></script>

Then in the view/controller just do:

var socket = io.connect()

That should solve your problem.

Differentiating between the possible origins of exceptions raised from a compound with statement

Differentiating between exceptions that occur in a with statement is tricky because they can originate in different places. Exceptions can be raised from either of the following places (or functions called therein):

• ContextManager.__init__
• ContextManager.__enter__
• the body of the with
• ContextManager.__exit__

For more details see the documentation about Context Manager Types.

If we want to distinguish between these different cases, just wrapping the with into a try .. except is not sufficient. Consider the following example (using ValueError as an example but of course it could be substituted with any other exception type):

try:
    with ContextManager():
        BLOCK
except ValueError as err:
    print(err)

Here the except will catch exceptions originating in all of the four different places and thus does not allow to distinguish between them. If we move the instantiation of the context manager object outside the with, we can distinguish between __init__ and BLOCK / __enter__ / __exit__:

try:
    mgr = ContextManager()
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        with mgr:
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
    except ValueError as err:
        # At this point we still cannot distinguish between exceptions raised from
        # __enter__, BLOCK, __exit__ (also BLOCK since we didn't catch ValueError in the body)
        pass

Effectively this just helped with the __init__ part but we can add an extra sentinel variable to check whether the body of the with started to execute (i.e. differentiating between __enter__ and the others):

try:
    mgr = ContextManager()  # __init__ could raise
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        entered_body = False
        with mgr:
            entered_body = True  # __enter__ did not raise at this point
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
    except ValueError as err:
        if not entered_body:
            print('__enter__ raised:', err)
        else:
            # At this point we know the exception came either from BLOCK or from __exit__
            pass

The tricky part is to differentiate between exceptions originating from BLOCK and __exit__ because an exception that escapes the body of the with will be passed to __exit__ which can decide how to handle it (see the docs). If however __exit__ raises itself, the original exception will be replaced by the new one. To deal with these cases we can add a general except clause in the body of the with to store any potential exception that would have otherwise escaped unnoticed and compare it with the one caught in the outermost except later on - if they are the same this means the origin was BLOCK or otherwise it was __exit__ (in case __exit__ suppresses the exception by returning a true value the outermost except will simply not be executed).

try:
    mgr = ContextManager()  # __init__ could raise
except ValueError as err:
    print('__init__ raised:', err)
else:
    entered_body = exc_escaped_from_body = False
    try:
        with mgr:
            entered_body = True  # __enter__ did not raise at this point
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
            except Exception as err:  # this exception would normally escape without notice
                # we store this exception to check in the outer `except` clause
                # whether it is the same (otherwise it comes from __exit__)
                exc_escaped_from_body = err
                raise  # re-raise since we didn't intend to handle it, just needed to store it
    except ValueError as err:
        if not entered_body:
            print('__enter__ raised:', err)
        elif err is exc_escaped_from_body:
            print('BLOCK raised:', err)
        else:
            print('__exit__ raised:', err)

Alternative approach using the equivalent form mentioned in PEP 343

PEP 343 -- The "with" Statement specifies an equivalent "non-with" version of the with statement. Here we can readily wrap the various parts with try ... except and thus differentiate between the different potential error sources:

import sys

try:
    mgr = ContextManager()
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        value = type(mgr).__enter__(mgr)
    except ValueError as err:
        print('__enter__ raised:', err)
    else:
        exit = type(mgr).__exit__
        exc = True
        try:
            try:
                BLOCK
            except TypeError:
                pass
            except:
                exc = False
                try:
                    exit_val = exit(mgr, *sys.exc_info())
                except ValueError as err:
                    print('__exit__ raised:', err)
                else:
                    if not exit_val:
                        raise
        except ValueError as err:
            print('BLOCK raised:', err)
        finally:
            if exc:
                try:
                    exit(mgr, None, None, None)
                except ValueError as err:
                    print('__exit__ raised:', err)

Usually a simpler approach will do just fine

The need for such special exception handling should be quite rare and normally wrapping the whole with in a try ... except block will be sufficient. Especially if the various error sources are indicated by different (custom) exception types (the context managers need to be designed accordingly) we can readily distinguish between them. For example:

try:
    with ContextManager():
        BLOCK
except InitError:  # raised from __init__
    ...
except AcquireResourceError:  # raised from __enter__
    ...
except ValueError:  # raised from BLOCK
    ...
except ReleaseResourceError:  # raised from __exit__
    ...

Jan 2020 Update

@Flimm has explained all the differences very well. Generally, we want to know the difference between all tools because we want to decide what's best for us. So, the next question would be: which one to use? I suggest you choose one of the two official ways to manage virtual environments:

• Python Packaging now recommends Pipenv
• Python.org now recommends venv

If you are creating a rootfs using debootstrap you will need to generate the locales. You can do this by running:

# (optional) enable missing locales
sudo nano /etc/locale.gen

# then regenerate
sudo locale-gen

This tip comes from, https://help.ubuntu.com/community/Xen

Using history.listen

For example like below:

In your component,

componentWillMount() {
    this.props.history.listen(() => {
      // Detecting, user has changed URL
      console.info(this.props.history.location.pathname);
    });
}

I've worked with a lot of CSV files in my time. I'd like to add the advice:

1 - Depending on the source (Excel, etc), commas or tabs may be embedded in a field. Usually, the rule is that they will be 'protected' because the field will be double-quote delimited, as in "Boston, MA 02346".

2 - Some sources will not double-quote delimit all text fields. Other sources will. Others will delimit all fields, even numerics.

3 - Fields containing double-quotes usually get the embedded double quotes doubled up (and the field itself delimited with double quotes, as in "George ""Babe"" Ruth".

4 - Some sources will embed CR/LFs (Excel is one of these!). Sometimes it'll be just a CR. The field will usually be double-quote delimited, but this situation is very difficult to handle.

C++03 (Source: Iterator Invalidation Rules (C++03))

Insertion

Sequence containers

• vector: all iterators and references before the point of insertion are unaffected, unless the new container size is greater than the previous capacity (in which case all iterators and references are invalidated) [23.2.4.3/1]
• deque: all iterators and references are invalidated, unless the inserted member is at an end (front or back) of the deque (in which case all iterators are invalidated, but references to elements are unaffected) [23.2.1.3/1]
• list: all iterators and references unaffected [23.2.2.3/1]

Associative containers

• [multi]{set,map}: all iterators and references unaffected [23.1.2/8]

Container adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Erasure

Sequence containers

• vector: every iterator and reference after the point of erase is invalidated [23.2.4.3/3]
• deque: all iterators and references are invalidated, unless the erased members are at an end (front or back) of the deque (in which case only iterators and references to the erased members are invalidated) [23.2.1.3/4]
• list: only the iterators and references to the erased element is invalidated [23.2.2.3/3]

Associative containers

• [multi]{set,map}: only iterators and references to the erased elements are invalidated [23.1.2/8]

Container adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Resizing

• vector: as per insert/erase [23.2.4.2/6]
• deque: as per insert/erase [23.2.1.2/1]
• list: as per insert/erase [23.2.2.2/1]

Note 1

Unless otherwise specified (either explicitly or by defining a function in terms of other functions), invoking a container member function or passing a container as an argument to a library function shall not invalidate iterators to, or change the values of, objects within that container. [23.1/11]

Note 2

It's not clear in C++2003 whether "end" iterators are subject to the above rules; you should assume, anyway, that they are (as this is the case in practice).

Note 3

The rules for invalidation of pointers are the sames as the rules for invalidation of references.

I have created a small utility function, this works well for me

def display_text_max_col_width(df, width):
    with pd.option_context('display.max_colwidth', width):
        print(df)

display_text_max_col_width(train_df["Description"], 800)

I can change length of the width as per my requirement, without setting any option permanently.

Use numpy.sum. for your case, it is

sum = a.sum(axis=0)

This error can be caused by putting the function definitions for a template class in a separate .cpp file. For a template class, the member functions have to be declared in the header file. You can resolve the issue by defining the member functions inline or right after the class definition in the .h file.

For example, instead of putting the function definitions in a .cpp file like for other classes, you could define them inline like this:

template<typename T>
MyClassName {
  void someFunction() {
    // Do something
    ...
  }
  void anotherFunction() {
    // Do something else
    ...
  }
}

Or you could define them after the class definition but in the same file, like this:

template<typename T>
MyClassName {
  void someFunction();
  void anotherFunction();
}

void MyClassName::someFunction() {
  // Do something
  ...
}
void MyClassName::anotherFunction() {
  // Do something else
  ...
}

I just thought I'd share that since no one else seems to have mentioned template classes. This was the cause of the error in my case.

This is the only thing that worked for me (with an ES6 class component):

componentDidMount() {
  ReactDOM.findDOMNode(this).scrollIntoView();
}

I've posted this comment on a seperate StackOverflow thread, but thought it was worth repeating here:

For our in-house ASP.Net app, adding the "X-UA-Compatible" tag on the web page, in the web.config or in the code-behind made absolutely no difference.

The only thing that worked for us was to manually turn off this setting in IE8:

(Sigh.)

This problem only seems to happen with IE8 & IE9 on intranet sites. External websites will work fine and use the correct version of IE8/9, but for internal websites, IE9 suddenly decides it's actually IE7, and doesn't have any HTML 5 support.

No, I don't quite understand this logic either.

My reluctant solution has been to test whether the browser has HTML 5 support (by creating a canvas, and testing if it's valid), and displaying this message to the user if it's not valid:

It's not particularly user-friendly, but getting the user to turn off this annoying setting seems to be the only way to let them run in-house HTML 5 web apps properly.

Or get the users to use Chrome. ;-)

If you want to use form's reset feature, you'd better to use this:

$('input[type=checkbox]').prop('checked',true); 

OR

$('input[type=checkbox]').prop('checked',false);

Looks like removeAttr() can not be reset by form.reset().

tl;dr: You don't have to remove the slashes, you have nested JSON, and hence have to decode the JSON twice: DEMO (note I used double slashes in the example, because the JSON is inside a JS string literal).

I assume that your actual JSON looks like

{"data":"{\n \"taskNames\" : [\n \"01 Jan\",\n \"02 Jan\",\n \"03 Jan\",\n \"04 Jan\",\n \"05 Jan\",\n \"06 Jan\",\n \"07 Jan\",\n \"08 Jan\",\n \"09 Jan\",\n \"10 Jan\",\n \"11 Jan\",\n \"12 Jan\",\n \"13 Jan\",\n \"14 Jan\",\n \"15 Jan\",\n \"16 Jan\",\n \"17 Jan\",\n \"18 Jan\",\n \"19 Jan\",\n \"20 Jan\",\n \"21 Jan\",\n \"22 Jan\",\n \"23 Jan\",\n \"24 Jan\",\n \"25 Jan\",\n \"26 Jan\",\n \"27 Jan\"]}"}

I.e. you have a top level object with one key, data. The value of that key is a string containing JSON itself. This is usually because the server side code didn't properly create the JSON. That's why you see the \" inside the string. This lets the parser know that " is to be treated literally and doesn't terminate the string.

So you can either fix the server side code, so that you don't double encode the data, or you have to decode the JSON twice, e.g.

var data = JSON.parse(JSON.parse(json).data));

You can use django-ipware which supports Python 2 & 3 and handles IPv4 & IPv6.

Install:

pip install django-ipware

Simple Usage:

# In a view or a middleware where the `request` object is available

from ipware import get_client_ip
ip, is_routable = get_client_ip(request)
if ip is None:
    # Unable to get the client's IP address
else:
    # We got the client's IP address
    if is_routable:
        # The client's IP address is publicly routable on the Internet
    else:
        # The client's IP address is private

# Order of precedence is (Public, Private, Loopback, None)

Advanced Usage:

• Custom Header - Custom request header for ipware to look at:

  i, r = get_client_ip(request, request_header_order=['X_FORWARDED_FOR'])
  i, r = get_client_ip(request, request_header_order=['X_FORWARDED_FOR', 'REMOTE_ADDR'])
  

• Proxy Count - Django server is behind a fixed number of proxies:

  i, r = get_client_ip(request, proxy_count=1)
  

• Trusted Proxies - Django server is behind one or more known & trusted proxies:

  i, r = get_client_ip(request, proxy_trusted_ips=('177.2.2.2'))
  
  # For multiple proxies, simply add them to the list
  i, r = get_client_ip(request, proxy_trusted_ips=('177.2.2.2', '177.3.3.3'))
  
  # For proxies with fixed sub-domain and dynamic IP addresses, use partial pattern
  i, r = get_client_ip(request, proxy_trusted_ips=('177.2.', '177.3.'))
  

Note: read this notice.

I would like to echo Jason's response though sometimes you need to naively parse some Html and pull out the text content.

I needed to do this with some Html which had been created by a rich text editor, always fun and games.

In this case you may need to remove the content of some tags as well as just the tags themselves.

In my case and tags were thrown into this mix. Some one may find my (very slightly) less naive implementation a useful starting point.

   /// <summary>
    /// Removes all html tags from string and leaves only plain text
    /// Removes content of <xml></xml> and <style></style> tags as aim to get text content not markup /meta data.
    /// </summary>
    /// <param name="input"></param>
    /// <returns></returns>
    public static string HtmlStrip(this string input)
    {
        input = Regex.Replace(input, "<style>(.|\n)*?</style>",string.Empty);
        input = Regex.Replace(input, @"<xml>(.|\n)*?</xml>", string.Empty); // remove all <xml></xml> tags and anything inbetween.  
        return Regex.Replace(input, @"<(.|\n)*?>", string.Empty); // remove any tags but not there content "<p>bob<span> johnson</span></p>" becomes "bob johnson"
    }

UPDATE: There are better options than my original answer. This works outside of MVC quite well but it's better to stick with the built-in methods of returning image content. See up-voted answers.

You certainly can. Try out these steps:

1. Load the image from disk in to a byte array
2. cache the image in the case you expect more requests for the image and don't want the disk I/O (my sample doesn't cache it below)
3. Change the mime type via the Response.ContentType
4. Response.BinaryWrite out the image byte array

Here's some sample code:

string pathToFile = @"C:\Documents and Settings\some_path.jpg";
byte[] imageData = File.ReadAllBytes(pathToFile);
Response.ContentType = "image/jpg";
Response.BinaryWrite(imageData);

Hope that helps!

I usually prefer the key sampling method to troubleshoot such scenarios.

redis-cli -p 6379 -n db_number --bigkeys

Eg:-

redis-cli -p 6370 -n 0 --bigkeys

I prefer the other methods already posted, but some people like to use:

case "$HOST" in 
    user1|node*) 
            echo "yes";;
        *)
            echo "no";;
esac

Edit:

I've added your alternates to the case statement above

In your edited version you have too many brackets. It should look like this:

if [[ $HOST == user1 || $HOST == node* ]];

@choz answer is the correct way. If you have many usages and want to make sure it works everywhere without changes you can add these small migration-snippet:

/* Migration jQuery from 1.8 to 3.x */
jQuery.fn.load = function (callback) {
    var el = $(this);

    el.on('load', callback);

    return el;
};

In this case you got no erros on other nodes e.g. on $image like in @Korsmakolnikov answer!

const $image = $('img.image').load(function() {
  $(this).doSomething();
});

$image.doSomethingElseWithTheImage();

I suggest a mix of using X-macros are the best solution and the following template functions:

To borrow off marcinkoziukmyopenidcom and extended

enum Colours {
#   define X(a) a,
#   include "colours.def"
#   undef X
    ColoursCount
};

char const* const colours_str[] = {
#   define X(a) #a,
#   include "colours.def"
#   undef X
    0
};

template <class T> T str2enum( const char* );
template <class T> const char* enum2str( T );

#define STR2ENUM(TYPE,ARRAY) \
template <> \
TYPE str2enum<TYPE>( const char* str ) \
    { \
    for( int i = 0; i < (sizeof(ARRAY)/sizeof(ARRAY[0])); i++ ) \
        if( !strcmp( ARRAY[i], str ) ) \
            return TYPE(i); \
    return TYPE(0); \
    }

#define ENUM2STR(TYPE,ARRAY) \
template <> \
const char* enum2str<TYPE>( TYPE v ) \
    { \
    return ARRAY[v]; \
    }

#define ENUMANDSTR(TYPE,ARRAY)\
    STR2ENUM(TYPE,ARRAY) \
    ENUM2STR(TYPE,ARRAY)

ENUMANDSTR(Colours,colours_str)

colour.def

X(Red)
X(Green)
X(Blue)
X(Cyan)
X(Yellow)
X(Magenta)

This should technically be achievable using window.location.reload():

HTML:

<button (click)="refresh()">Refresh</button>

TS:

refresh(): void {
    window.location.reload();
}

Update:

Here is a basic StackBlitz example showing the refresh in action. Notice the URL on "/hello" path is retained when window.location.reload() is executed.

You better setup a single test and create a performance test from this test. This way you can monitor the progress using the default tool set.

I know the answer is in reply to a question asked 6 years ago ...

But I was looking for something similar for a few hours and then found out that: cut -c does exactly that, with an added bonus that you could also specify an offset.

cut -c 1-5 will return Hello and cut -c 7-11 will return world. No need for any other command

I have python2.7 installed via brew and the following solved my problem

brew install numpy

It installs python3, but it still works and sets it up for 2.7 as well.

Not 100% sure what you mean:

Trusted_Connection=True;

IS using Windows credentials and is 100% equivalent to:

Integrated Security=SSPI;

or

Integrated Security=true;

If you don't want to use integrated security / trusted connection, you need to specify user id and password explicitly in the connection string (and leave out any reference to Trusted_Connection or Integrated Security)

server=yourservername;database=yourdatabase;user id=YourUser;pwd=TopSecret

Only in this case, the SQL Server authentication mode is used.

If any of these two settings is present (Trusted_Connection=true or Integrated Security=true/SSPI), then the Windows credentials of the current user are used to authenticate against SQL Server and any user iD= setting will be ignored and not used.

For reference, see the Connection Strings site for SQL Server 2005 with lots of samples and explanations.

Using Windows Authentication is the preferred and recommended way of doing things, but it might incur a slight delay since SQL Server would have to authenticate your credentials against Active Directory (typically). I have no idea how much that slight delay might be, and I haven't found any references for that.

Summing up:

If you specify either Trusted_Connection=True; or Integrated Security=SSPI; or Integrated Security=true; in your connection string

==> THEN (and only then) you have Windows Authentication happening. Any user id= setting in the connection string will be ignored.

If you DO NOT specify either of those settings,

==> then you DO NOT have Windows Authentication happening (SQL Authentication mode will be used)

The best solution is just not to use anonymous classes.

            Console.WriteLine("A = '{0}', B = '{1}'", value.A, value.B);
        }
    }
}

Note that you need to cast the result of the query to the type of the interface. There might be a better way to do it, but I couldn't find it.

Note: This will completely remove nodejs from your system; then you can make a fresh install from the below commands.

Removing Nodejs and Npm

sudo apt-get remove nodejs npm node
sudo apt-get purge nodejs

Now remove .node and .npm folders from your system

sudo rm -rf /usr/local/bin/npm 
sudo rm -rf /usr/local/share/man/man1/node* 
sudo rm -rf /usr/local/lib/dtrace/node.d 
sudo rm -rf ~/.npm 
sudo rm -rf ~/.node-gyp 
sudo rm -rf /opt/local/bin/node 
sudo rm -rf opt/local/include/node 
sudo rm -rf /opt/local/lib/node_modules  

sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/include/node*
sudo rm -rf /usr/local/bin/node*

Go to home directory and remove any node or node_modules directory, if exists.

You can verify your uninstallation by these commands; they should not output anything.

which node
which nodejs
which npm

Installing NVM (Node Version Manager) by downloading and running a script

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash

The command above will clone the NVM repository from Github to the ~/.nvm directory:

Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

As the output above says, you should either close and reopen the terminal or run the commands to add the path to nvm script to the current shell session. You can do whatever is easier for you.

Once the script is in your PATH, verify that nvm was properly installed by typing:

nvm --version

which should give this output:

0.34.0

Installing Node.js and npm

nvm install node
nvm install --lts

Once the installation is completed, verify it by printing the Node.js version:

node --version

should give this output:

v12.8.1

Npm should also be installed with node, verify it using

npm -v

should give:

6.13.4

Extra - [Optional] You can also use two different versions of node using nvm easily

nvm install 8.10.0 # just put the node version number Now switch between node versions

$ nvm ls
->     v12.14.1
        v13.7.0
default -> lts/* (-> v12.14.1)
node -> stable (-> v13.7.0) (default)
stable -> 13.7 (-> v13.7.0) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/erbium (-> v12.14.1)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.18.1 (-> N/A)

In my case v12.14.1 and v13.7.0 both are installed, to switch I have to just use

nvm use 12.14.1

Configuring npm for global installations In your home directory, create a directory for global installations:

mkdir ~/.npm-global

Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'

In your preferred text editor, open or create a ~/.profile file if does not exist and add this line:

PATH="$HOME/.npm-global/bin:$PATH"

On the command line, update your system variables:

source ~/.profile

That's all

I also got stuck with this issue. I got correct response from server, but couldn`t play video. After long time I found a solution here. Maybe, in future this link will be invalid. So, here is my correct code

    Uri video = Uri.parse("Your link should be in this place "); 
    mVideoView.setVideoURI(video); 

   mVideoView.setZOrderOnTop(true); //Very important line, add it to Your code
    mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
        @Override 
        public void onPrepared(MediaPlayer mediaPlayer) {
  // here write another part of code, which provides starting the video
  }}

The .git folder is only stored in the root directory of the repo, not all the sub-directories like subversion. You should be able to just delete that one folder, unless you are using Submodules...then they will have one too.

Just add a new form and add buttons and a label. Give the value to be shown and the text of the button, etc. in its constructor, and call it from anywhere you want in the project.

In project -> Add Component -> Windows Form and select a form

Add some label and buttons.

Initialize the value in constructor and call it from anywhere.

public class form1:System.Windows.Forms.Form
{
    public form1()
    {
    }

    public form1(string message,string buttonText1,string buttonText2)
    {
       lblMessage.Text = message;
       button1.Text = buttonText1;
       button2.Text = buttonText2;
    }
}

// Write code for button1 and button2 's click event in order to call 
// from any where in your current project.

// Calling

Form1 frm = new Form1("message to show", "buttontext1", "buttontext2");
frm.ShowDialog();

You can simply iterate through the DbSet context.tablename

foreach(var row in context.tablename)
  Console.WriteLn(row.field);

or to evaluate immediately into your own list

var allRows = context.tablename.ToList();

A good information: you don't need to check whether the Bundle object is null into the onCreate() method. Use the onRestoreInstanceState() method, which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null

Make sure you follow the language definition for JSON. In your second example, the section:

"labs":[{
    ""
}]

Is invalid since an object must be composed of zero or more key-value pairs "a" : "b", where "b" may be any valid value. Some parsers may automatically interpret { "" } to be { "" : null }, but this is not a clearly defined case.

Also, you are using a nested array of objects [{}] quite a bit. I would only do this if:

1. There is no good "identifier" string for each object in the array.
2. There is some clear reason for having an array over a key-value for that entry.

The query can be written slightly simpler, like this:

DECLARE @T INT = 2 

SELECT CASE 
         WHEN @T < 1 THEN 'less than one' 
         WHEN @T = 1 THEN 'one' 
         ELSE 'greater than one' 
       END T

Using SQL Server 2008, you can create a filtered index: http://msdn.microsoft.com/en-us/library/cc280372.aspx. (I see Simon added this as a comment, but thought it deserved its own answer as the comment is easily missed.)

Another option is a trigger to check uniqueness, but this could affect performance.

I combined some of the answers and added a way to scale the stress to all available cpus:

#!/bin/bash

function infinite_loop { 
    while [ 1 ] ; do
        # Force some computation even if it is useless to actually work the CPU
        echo $((13**99)) 1>/dev/null 2>&1
    done
}

# Either use environment variables for DURATION, or define them here
NUM_CPU=$(grep -c ^processor /proc/cpuinfo 2>/dev/null || sysctl -n hw.ncpu)
PIDS=()
for i in `seq ${NUM_CPU}` ;
do
# Put an infinite loop on each CPU
    infinite_loop &
    PIDS+=("$!")
done

# Wait DURATION seconds then stop the loops and quit
sleep ${DURATION}

# Parent kills its children 
for pid in "${PIDS[@]}"
do
    kill $pid
done

Textarea resize control is available via the CSS3 resize property:

textarea { resize: both; } /* none|horizontal|vertical|both */
textarea.resize-vertical{ resize: vertical; }
textarea.resize-none { resize: none; }

Allowable values self-explanatory: none (disables textarea resizing), both, vertical and horizontal.

Notice that in Chrome, Firefox and Safari the default is both.

If you want to constrain the width and height of the textarea element, that's not a problem: these browsers also respect max-height, max-width, min-height, and min-width CSS properties to provide resizing within certain proportions.

Code example:

#textarea-wrapper {_x000D_
  padding: 10px;_x000D_
  background-color: #f4f4f4;_x000D_
  width: 300px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea {_x000D_
  min-height:50px;_x000D_
  max-height:120px;_x000D_
  width: 290px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea.vertical { _x000D_
  resize: vertical;_x000D_
}

<div id="textarea-wrapper">_x000D_
  <label for="resize-default">Textarea (default):</label>_x000D_
  <textarea name="resize-default" id="resize-default"></textarea>_x000D_
  _x000D_
  <label for="resize-vertical">Textarea (vertical):</label>_x000D_
  <textarea name="resize-vertical" id="resize-vertical" class="vertical">Notice this allows only vertical resize!</textarea>_x000D_
</div>

Update I've tidied up the SwingLink class further and added more features; an up-to-date copy of it can be found here: https://bitbucket.org/dimo414/jgrep/src/tip/src/grep/SwingLink.java

@McDowell's answer is great, but there's several things that could be improved upon. Notably text other than the hyperlink is clickable and it still looks like a button even though some of the styling has been changed/hidden. While accessibility is important, a coherent UI is as well.

So I put together a class extending JLabel based on McDowell's code. It's self-contained, handles errors properly, and feels more like a link:

public class SwingLink extends JLabel {
  private static final long serialVersionUID = 8273875024682878518L;
  private String text;
  private URI uri;

  public SwingLink(String text, URI uri){
    super();
    setup(text,uri);
  }

  public SwingLink(String text, String uri){
    super();
    setup(text,URI.create(uri));
  }

  public void setup(String t, URI u){
    text = t;
    uri = u;
    setText(text);
    setToolTipText(uri.toString());
    addMouseListener(new MouseAdapter() {
      public void mouseClicked(MouseEvent e) {
        open(uri);
      }
      public void mouseEntered(MouseEvent e) {
        setText(text,false);
      }
      public void mouseExited(MouseEvent e) {
        setText(text,true);
      }
    });
  }

  @Override
  public void setText(String text){
    setText(text,true);
  }

  public void setText(String text, boolean ul){
    String link = ul ? "<u>"+text+"</u>" : text;
    super.setText("<html><span style=\"color: #000099;\">"+
    link+"</span></html>");
    this.text = text;
  }

  public String getRawText(){
    return text;
  }

  private static void open(URI uri) {
    if (Desktop.isDesktopSupported()) {
      Desktop desktop = Desktop.getDesktop();
      try {
        desktop.browse(uri);
      } catch (IOException e) {
        JOptionPane.showMessageDialog(null,
            "Failed to launch the link, your computer is likely misconfigured.",
            "Cannot Launch Link",JOptionPane.WARNING_MESSAGE);
      }
    } else {
      JOptionPane.showMessageDialog(null,
          "Java is not able to launch links on your computer.",
          "Cannot Launch Link", JOptionPane.WARNING_MESSAGE);
    }
  }
}

You could also, for instance, change the link color to purple after being clicked, if that seemed useful. It's all self contained, you simply call:

SwingLink link = new SwingLink("Java", "http://java.sun.com");
mainPanel.add(link);

You shouldn't need a callback for iterating through a list. Just add the end() call after the loop.

posts.forEach(function(v, i){
   res.write(v + ". Index " + i);
});
res.end();

You can also try background:none;border:0px to buttons.

also the css selectors are div#yes button{..} and div#no button{..} . hopes it helps

You can do this using groupby to group on the column of interest and then apply list to every group:

In [1]: df = pd.DataFrame( {'a':['A','A','B','B','B','C'], 'b':[1,2,5,5,4,6]})
        df

Out[1]: 
   a  b
0  A  1
1  A  2
2  B  5
3  B  5
4  B  4
5  C  6

In [2]: df.groupby('a')['b'].apply(list)
Out[2]: 
a
A       [1, 2]
B    [5, 5, 4]
C          [6]
Name: b, dtype: object

In [3]: df1 = df.groupby('a')['b'].apply(list).reset_index(name='new')
        df1
Out[3]: 
   a        new
0  A     [1, 2]
1  B  [5, 5, 4]
2  C        [6]

If you have IIS Express (with Visual Studio):

To enable the SSL within IIS Express, you have to just set “SSL Enabled = true” in the project properties window.

See the steps and pictures at this code project.

IIS Express will generate a certificate for you (you'll be prompted for it, etc.). Note that depending on configuration the site may still automatically start with the URL rather than the SSL URL. You can see the SSL URL - note the port number and replace it in your browser address bar, you should be able to get in and test.

From there you can right click on your project, click property pages, then start options and assign the start URL - put the new https with the new port (usually 44301 - notice the similarity to port 443) and your project will start correctly from then on.

I have tried this with your data and it is working :

%pyspark
import pandas as pd
from pyspark.sql import SQLContext
print sc
df = pd.read_csv("test.csv")
print type(df)
print df
sqlCtx = SQLContext(sc)
sqlCtx.createDataFrame(df).show()

The minimum length is 4 for Saint Helena (Format: +290 XXXX) and Niue (Format: +683 XXXX).

Swift 4, 5

To pin a view to a safe area anchor using constraints can be done anywhere in the view controller's lifecycle because they're queued by the API and handled after the view has been loaded into memory. However, getting safe-area values requires waiting toward the end of a view controller's lifecycle, like viewDidLayoutSubviews().

This plugs into any view controller:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    let topSafeArea: CGFloat
    let bottomSafeArea: CGFloat

    if #available(iOS 11.0, *) {
        topSafeArea = view.safeAreaInsets.top
        bottomSafeArea = view.safeAreaInsets.bottom
    } else {
        topSafeArea = topLayoutGuide.length
        bottomSafeArea = bottomLayoutGuide.length
    }

    // safe area values are now available to use
}

I prefer this method to getting it off of the window (when possible) because it’s how the API was designed and, more importantly, the values are updated during all view changes, like device orientation changes.

However, some custom presented view controllers cannot use the above method (I suspect because they are in transient container views). In such cases, you can get the values off of the root view controller, which will always be available anywhere in the current view controller's lifecycle.

anyLifecycleMethod()
    guard let root = UIApplication.shared.keyWindow?.rootViewController else {
        return
    }
    let topSafeArea: CGFloat
    let bottomSafeArea: CGFloat

    if #available(iOS 11.0, *) {
        topSafeArea = root.view.safeAreaInsets.top
        bottomSafeArea = root.view.safeAreaInsets.bottom
    } else {
        topSafeArea = root.topLayoutGuide.length
        bottomSafeArea = root.bottomLayoutGuide.length
    }

    // safe area values are now available to use
}

The only way to remove the dotted line (to my knowledge) is with css hacking using plugin.

• Install the User CSS (or User JS & CSS) plugin, which allows adding CSS rules per site.

• Once on Google Docs, click the plugins icon, toggle the OFF to ON button, and add the following css code:

.

.kix-page-compact::before{
    border-top: none;
}

Should work like a charm.

In order to get the PHP output into the HTML file you need to either

• Change the extension of the HTML to file to PHP and include the PHP from there (simple)
• Load your HTML file into your PHP as a kind of template (a lot of work)
• Change your environment so it deals with HTML as if it was PHP (bad idea)

Faster clearing than Arrays.fill is with this (From Fast Serialization Lib). I just use arrayCopy (is native) to clear the array:

static Object[] EmptyObjArray = new Object[10000];

public static void clear(Object[] arr) {
    final int arrlen = arr.length;
    clear(arr, arrlen);
}

public static void clear(Object[] arr, int arrlen) {
    int count = 0;
    final int length = EmptyObjArray.length;
    while( arrlen - count > length) {
        System.arraycopy(EmptyObjArray,0,arr,count, length);
        count += length;
    }
    System.arraycopy(EmptyObjArray,0,arr,count, arrlen -count);
}

There are several options. You can use the WebMethod attribute, for your purpose.

Tensorflow 2.1

A simple calculation that can be verified with nvidia-smi for memory usage on the GPU.

import tensorflow as tf 

c1 = []
n = 10

def matpow(M, n):
    if n < 1: #Abstract cases where n < 1
        return M
    else:
        return tf.matmul(M, matpow(M, n-1))

with tf.device('/gpu:0'):
    a = tf.Variable(tf.random.uniform(shape=(10000, 10000)), name="a")
    b = tf.Variable(tf.random.uniform(shape=(10000, 10000)), name="b")
    c1.append(matpow(a, n))
    c1.append(matpow(b, n))

This simple mechanism you can use for detecting finishing of a thread without blocking in join method.

std::thread thread([&thread]() {
    sleep(3);
    thread.detach();
});

while(thread.joinable())
    sleep(1);

Okay, I'll bite. You want something like this: If you declare a "property" like this:

Update: I'm now pretty sure that Fredrik Mörk answered your question and gave a solution. I'm not really happy with the idea, but it seems to answer exactly what I understood from your question.

public class PropertyFoo {
  public MyProp<String> Name;
}

this ends up as

public class PropertyFoo {
  public string Name {
    get { /* do predefined stuff here */ }
    set { /*other predefined stuff here */ }
  }
}

No. Not possible and not a property, really. Look for template/snippet support in your IDE.

As @Jared Ng and @Issun pointed out, the key to solve this kind of RegEx like "matching everything up to a certain word or substring" or "matching everything after a certain word or substring" is called "lookaround" zero-length assertions. Read more about them here.

In your particular case, it can be solved by a positive look ahead: .+?(?=abc)

A picture is worth a thousand words. See the detail explanation in the screenshot.

Setting async to false means the instructions following the ajax request will have to wait for the request to complete. Below is one case where one have to set async to false, for the code to work properly.

var phpData = (function get_php_data() {
  var php_data;
  $.ajax({
    url: "http://somesite/v1/api/get_php_data",
    async: false, 
    //very important: else php_data will be returned even before we get Json from the url
    dataType: 'json',
    success: function (json) {
      php_data = json;
    }
  });
  return php_data;
})();

Above example clearly explains the usage of async:false

By setting it to false, we have made sure that once the data is retreived from the url ,only after that return php_data; is called

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

df = df.loc[:, ~df.columns.str.contains('^Unnamed')]

In [162]: df
Out[162]:
   colA  ColB  colC  colD  colE  colF  colG
0    44    45    26    26    40    26    46
1    47    16    38    47    48    22    37
2    19    28    36    18    40    18    46
3    50    14    12    33    12    44    23
4    39    47    16    42    33    48    38

if the first column in the CSV file has index values, then you can do this instead:

df = pd.read_csv('data.csv', index_col=0)

Quote from Android Docs:

If you need to format your strings using String.format(String, Object...), then you can do so by putting your format arguments in the string resource. For example, with the following resource:

<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

In this example, the format string has two arguments: %1$s is a string and %2$d is a decimal number. You can format the string with arguments from your application like this:

Resources res = getResources();
String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);

I know this is not fully relevant, but since this answer is ranked first many a times when you search 'how to display images in Jupyter', please consider this answer as well.

You could use matplotlib to show an image as follows.

import matplotlib.pyplot as plt
import matplotlib.image as mpimg
image = mpimg.imread("your_image.png")
plt.imshow(image)
plt.show()

If $a is the array that's passed, $a[76][0]['id'] should give '76' and $a[76][1]['id'] should give '81', but I can't test as I don't have PHP installed on this machine.

use continue keyword .

EX:

for(int i = 0; i < 10; i++){
  if(i == 5){
    continue;
   }
}

if you want to use "System.Data.Objects.EntityFunctions"

use "System.Data.Entity.DbFunctions" in EF 6.1+

realloc is a pretty expensive action... here's my way of receiving a string, the realloc ratio is not 1:1 :

char* getAString()
{    
    //define two indexes, one for logical size, other for physical
    int logSize = 0, phySize = 1;  
    char *res, c;

    res = (char *)malloc(sizeof(char));

    //get a char from user, first time outside the loop
    c = getchar();

    //define the condition to stop receiving data
    while(c != '\n')
    {
        if(logSize == phySize)
        {
            phySize *= 2;
            res = (char *)realloc(res, sizeof(char) * phySize);
        }
        res[logSize++] = c;
        c = getchar();
    }
    //here we diminish string to actual logical size, plus one for \0
    res = (char *)realloc(res, sizeof(char *) * (logSize + 1));
    res[logSize] = '\0';
    return res;
}

One way to do it is to check what mysql_num_rows returns. A minimal complete example would be the following:

if ($result = mysql_query($sql) && mysql_num_rows($result) > 0) {
    // there are results in $result
} else {
    // no results
}

But it's recommended that you check the return value of mysql_query and handle it properly in the case it's false (which would be caused by an error); probably by also calling mysql_error and logging the error somewhere.

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

public static void Main(string[] args)
{
    int[] numbers = new int[10];

    Console.Write("index ");

    for (int i = 0; i < numbers.Length; i++)
    {
        numbers[i] = i;
        Console.Write(numbers[i] + " ");
    }

    Console.WriteLine("");
    Console.WriteLine("");
    Console.Write("value ");

    for (int i = 0; i < numbers.Length; i++)
    {
        numbers[i] = numbers.Length - i;
        Console.Write(numbers[i] + " ");
    }

    Console.ReadKey();
}

I needed this today, and although the answers already given pointed me in the right direction, they weren't quite what I wanted.

Here's an implementation using Heap's method. The length of the array must be at least 3 and for practical considerations not be bigger than 10 or so, depending on what you want to do, patience and clock speed.

Before you enter your loop, initialise Perm(1 To N) with the first permutation, Stack(3 To N) with zeroes*, and Level with 2**. At the end of the loop call NextPerm, which will return false when we're done.

* VB will do that for you.

** You can change NextPerm a little to make this unnecessary, but it's clearer like this.

Option Explicit

Function NextPerm(Perm() As Long, Stack() As Long, Level As Long) As Boolean
Dim N As Long
If Level = 2 Then
    Swap Perm(1), Perm(2)
    Level = 3
Else
    While Stack(Level) = Level - 1
        Stack(Level) = 0
        If Level = UBound(Stack) Then Exit Function
        Level = Level + 1
    Wend
    Stack(Level) = Stack(Level) + 1
    If Level And 1 Then N = 1 Else N = Stack(Level)
    Swap Perm(N), Perm(Level)
    Level = 2
End If
NextPerm = True
End Function

Sub Swap(A As Long, B As Long)
A = A Xor B
B = A Xor B
A = A Xor B
End Sub

'This is just for testing.
Private Sub Form_Paint()
Const Max = 8
Dim A(1 To Max) As Long, I As Long
Dim S(3 To Max) As Long, J As Long
Dim Test As New Collection, T As String
For I = 1 To UBound(A)
    A(I) = I
Next
Cls
ScaleLeft = 0
J = 2
Do
    If CurrentY + TextHeight("0") > ScaleHeight Then
        ScaleLeft = ScaleLeft - TextWidth(" 0 ") * (UBound(A) + 1)
        CurrentY = 0
        CurrentX = 0
    End If
    T = vbNullString
    For I = 1 To UBound(A)
        Print A(I);
        T = T & Hex(A(I))
    Next
    Print
    Test.Add Null, T
Loop While NextPerm(A, S, J)
J = 1
For I = 2 To UBound(A)
    J = J * I
Next
If J <> Test.Count Then Stop
End Sub

Other methods are described by various authors. Knuth describes two, one gives lexical order, but is complex and slow, the other is known as the method of plain changes. Jie Gao and Dianjun Wang also wrote an interesting paper.

Simple:

$url = "http://php.net/manual/en/function.preg-match.php";
preg_match("/http:\/\/php\.net(.+)\.php/", $url, $matches);
echo $matches[1];

$matches[0] is your full URL, $matches[1] is the part you want.

In addition to Richard Cresswells and dpbradleys answer: If you neither want to create a TNS name nor the '//123.45.67.89:1521/Test' input works (some configurations wont), you can put

(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 123.45.67.89)(PORT = 1521)) (CONNECT_DATA = (SID = TEST)(SERVER = DEDICATED)))

(as one line) into the 'database' section of the login dialog.

Yes, we can run docker in docker, we'll need to attach the unix sockeet "/var/run/docker.sock" on which the docker daemon listens by default as volume to the parent docker using "-v /var/run/docker.sock:/var/run/docker.sock". Sometimes, permissions issues may arise for docker daemon socket for which you can write "sudo chmod 757 /var/run/docker.sock".

And also it would require to run the docker in privileged mode, so the commands would be:

sudo chmod 757 /var/run/docker.sock

docker run --privileged=true -v /var/run/docker.sock:/var/run/docker.sock -it ...

I used a style to solve this issue. The official link is here.

Pretty useful stuff. You make a file to hold your styles (like "styles.xml"), and define them inside it. You then reference the styles in your layout (like "main.xml").

Here's a sample style that does what you want:

<style name="text_line_spacing">
   <item name="android:lineSpacingMultiplier">1.4</item>
</style>

Let's say you want to alter a simple TextView with this. In your layout file you'd type:

<TextView
   style="@style/summary_text"
   ...
   android:text="This sentence has 1.4 times more spacing than normal."
/>

Try it--this is essentially how all the built-in UI is done on the android. And by using styles, you have the option to modify all sorts of other aspects of your Views as well.

The most effective one liner that

• returns a boolean (as opposed to Orbling's answer)
• Does not return a false positive when searching for thisClass on an element that has class="thisClass-suffix".
• is compatible with every browser down to at least IE6

function hasClass( target, className ) {
    return new RegExp('(\\s|^)' + className + '(\\s|$)').test(target.className);
}
