In your IntelliJ idea find tools.jar replace it with tools.jar from yout JDK8

requirement for tkinter:

python 3.6+

and go to shell write the test code like :

from tkinter import *

root = Tk()

root.mainloop()

With debug turned off Django won't handle static files for you any more - your production web server (Apache or something) should take care of that.

• Check if there any other instance of the server is running already
• Check if the port that will be used by the server is free.

Copy Database to an other folder and attach or Log in SQLServer with "Windows Authentication"

You can use brace expansion in bash:

cp /home/ankur/folder/{file1,abc,xyz} /path/to/target

TRY THIS

declare 
  a number;
begin
  a := :a;
dbms_output.put_line('Inputed Number is >> '|| a);
end;
/  

OR

declare 
  a number;
begin
  a := :x;
dbms_output.put_line('Inputed Number is >> '|| a);
end;
/

This solved my 720 problem. The idea is to change the driver of the faulty WAN to another network adaptar driver, and then we are able to uninstall the WAN device and then reboot the system.

You can just add the word vectors of one sentence together. Then count the Cosine similarity of two sentence vector as the similarity of two sentence. I think that's the most easy way.

Create a XIB file :

File -> new File ->ios->cocoa touch class -> next

make sure check mark "also create XIB file"

I would like to perform with tableview so I choosed subclass UITableViewCell

you can choose as your requerment

XIB file desing as your wish (RestaurantTableViewCell.xib)

we need to grab the row height to set table each row hegiht

Now! need to huck them swift file . i am hucked the restaurantPhoto and restaurantName you can huck all of you .

Now adding a UITableView

name
The name of the nib file, which need not include the .nib extension.

owner
The object to assign as the nib’s File's Owner object.

options
A dictionary containing the options to use when opening the nib file.

first if you do not define first then grabing all view .. so you need to grab one view inside that set frist .

Bundle.main.loadNibNamed("yourUIView", owner: self, options: nil)?.first as! yourUIView

here is table view controller Full code

import UIKit

class RestaurantTableViewController: UIViewController ,UITableViewDataSource,UITableViewDelegate{

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 5
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let restaurantTableviewCell = Bundle.main.loadNibNamed("RestaurantTableViewCell", owner: self, options: nil)?.first as! RestaurantTableViewCell

        restaurantTableviewCell.restaurantPhoto.image = UIImage(named: "image1")
        restaurantTableviewCell.restaurantName.text = "KFC Chicken"

        return restaurantTableviewCell
    }
   // set row height
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 150
    }

}

you done :)

DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.

That is, try adding -lpthread to your command line.

A basic and very simple way of doing this without any code required would be to just provide an empty alt statement. The browser will then return the image as blank. It would look just like if the image isn't there.

Example:

<img class="img_gal" alt="" src="awesome.jpg">

Try it out to see! ;)

Below is the program to execute the rest api in python-

import requests
url = 'https://url'
data = '{  "platform": {    "login": {      "userName": "name",      "password": "pwd"    }  } }'
response = requests.post(url, data=data,headers={"Content-Type": "application/json"})
print(response)
sid=response.json()['platform']['login']['sessionId']   //to extract the detail from response
print(response.text)
print(sid)

Only this worked for me:

searchKeyword.replace(/'/g, "\\\'");//searchKeyword contains "d'av"

So, the result variable will contain "d\'av".

I don't know why with the RegEx didn't work, maybe because of the JS framework that I'm using (Backbone.js)

Angular6 using the renderer2 without any variables and a clean template:

template:

<div (click)="toggleClass($event,'testClass')"></div>

in ts:

toggleClass(event: any, class: string) {
  const hasClass = event.target.classList.contains(class);

  if(hasClass) {
    this.renderer.removeClass(event.target, class);
  } else {
    this.renderer.addClass(event.target, class);
  }
}

One could put this in a directive too ;)

In your example parts of your passed-in URL are not URL encoded (for example the colon should be %3A, the forward slashes should be %2F). It looks like you have encoded the parameters to your parameter URL, but not the parameter URL itself. Try encoding it as well. You can use encodeURIComponent.

I think that you are after this:

SELECT image_id
FROM list
WHERE (style_id, style_value) IN ((24,'red'),(25,'big'),(27,'round'))
GROUP BY image_id
HAVING count(distinct style_id, style_value)=3

You can't use AND, because values can't be 24 red and 25 big and 27 round at the same time in the same row, but you need to check the presence of style_id, style_value in multiple rows, under the same image_id.

In this query I'm using IN (that, in this particular example, is equivalent to an OR), and I am counting the distinct rows that match. If 3 distinct rows match, it means that all 3 attributes are present for that image_id, and my query will return it.

As Waylon Flinn said:

Turing Complete means that it is at least as powerful as a Turing Machine.

I believe this is incorrect, a system is Turing complete if it's exactly as powerful as the Turing Machine, i.e. every computation done by the machine can be done by the system, but also every computation done by the system can be done by the Turing machine.

The answer given by FelixFett worked for me. To reiterate:

<meta http-equiv="X-UA-Compatible" content="IE=11; IE=10; IE=9; IE=8; IE=7; IE=EDGE" />

I have it as the first 'meta' tag in my code. I added 10 and 11 as those are versions that are published now for Internet Explorer.

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

You need to first transform data1, in your case by calling ToString() on each element.

Use this if you want to return strings.

List<int> data1 = new List<int> {1,2,3,4,5};
List<string> data2 = new List<string>{"6","3"};

var newData = data1.Select(i => i.ToString()).Intersect(data2);

Use this if you want to return integers.

List<int> data1 = new List<int> {1,2,3,4,5};
List<string> data2 = new List<string>{"6","3"};

var newData = data1.Intersect(data2.Select(s => int.Parse(s));

Note that this will throw an exception if not all strings are numbers. So you could do the following first to check:

int temp;
if(data2.All(s => int.TryParse(s, out temp)))
{
    // All data2 strings are int's
}

# Let arr be the given array.
# And K be the give sum


for i=0 to arr.length - 1 do
  # key is the element and value is its index.
  hash(arr[i]) = i  
end-for

for i=0 to arr.length - 1 do
  # if K-th element exists and it's different then we found a pair
  if hash(K - arr[i]) != i  
    print "pair i , hash(K - arr[i]) has sum K"
  end-if
end-for

Here is an option using dplyr. The %<>% operator from magrittr update the lhs object with the resulting value.

library(magrittr)
library(dplyr)
cols <- c("A", "C", "D", "H")

data %<>%
       mutate_each_(funs(factor(.)),cols)
str(data)
#'data.frame':  4 obs. of  10 variables:
# $ A: Factor w/ 4 levels "23","24","26",..: 1 2 3 4
# $ B: int  15 13 39 16
# $ C: Factor w/ 4 levels "3","5","18","37": 2 1 3 4
# $ D: Factor w/ 4 levels "2","6","28","38": 3 1 4 2
# $ E: int  14 4 22 20
# $ F: int  7 19 36 27
# $ G: int  35 40 21 10
# $ H: Factor w/ 4 levels "11","29","32",..: 1 4 3 2
# $ I: int  17 1 9 25
# $ J: int  12 30 8 33

Or if we are using data.table, either use a for loop with set

setDT(data)
for(j in cols){
  set(data, i=NULL, j=j, value=factor(data[[j]]))
}

Or we can specify the 'cols' in .SDcols and assign (:=) the rhs to 'cols'

setDT(data)[, (cols):= lapply(.SD, factor), .SDcols=cols]

INSERT INTO homestead.bb_migrations (`migration`, `batch`)  VALUES ('2016_01_21_064436_create_victory_point_balance_table', '2')

something like this

Another method for creating a JavaScript associative array

First create an array of objects,

 var arr = {'name': []};

Next, push the value to the object.

  var val = 2;
  arr['name'].push(val);

To read from it:

var val = arr.name[0];

I have a solution that works well for me. It consists of a local jenkins running in docker and a git web hook to trigger the pipeline in the local jenkins on every commit. You no longer need to push to your github or bitbucket repository to test the pipeline.

This has only been tested in a linux environment.

It is fairly simple to make this work although this instruction is a tad long. Most steps are there.

This is what you need

• Docker installed and working. This is not part of this instruction.
• A Jenkins running in docker locally. Explained how below.
  • The proper rights (ssh access key) for your local Jenkins docker user to pull from your local git repo. Explained how below.
  • A Jenkins pipeline project that pulls from your local git repository. Explained below.
  • A git user in your local Jenkins with minimal rights. Explained below.
• A git project with a post-commit web hook that triggers the pipeline project. Explained below.

This is how you do it

Jenkins Docker

Create a file called Dockerfile in place of your choosing. I'm placing it in /opt/docker/jenkins/Dockerfile fill it with this:

FROM jenkins/jenkins:lts
USER root
RUN apt-get -y update && apt-get -y upgrade
# Your needed installations goes here
USER jenkins

Build the local_jenkins image

This you will need to do only once or after you have added something to the Dockerfile.

$ docker build -t local_jenkins /opt/docker/jenkins/

Start and restart local_jenkins

From time to time you want to start and restart jenkins easily. E.g. after a reboot of your machine. For this I made an alias that I put in .bash_aliases in my home folder.

$ echo "alias localjenkinsrestart='docker stop jenkins;docker rm jenkins;docker run --name jenkins -i -d -p 8787:8080 -p 50000:50000 -v /opt/docker/jenkins/jenkins_home:/var/jenkins_home:rw local_jenkins'" >> ~/.bash_aliases
$ source .bash_aliases  # To make it work

Make sure the /opt/docker/jenkins/jenkins_home folder exists and that you have user read and write rights to it.

To start or restart your jenkins just type:

$ localjenkinsrestart

Everything you do in your local jenkins will be stored in the folder /opt/docker/jenkins/jenkins_home and preserved between restarts.

Create a ssh access key in your docker jenkins

This is a very important part for this to work. First we start the docker container and create a bash shell to it:

$ localjenkinsrestart
$ docker exec -it jenkins /bin/bash

You have now entered into the docker container, this you can see by something like jenkins@e7b23bad10aa:/$ in your terminal. The hash after the @ will for sure differ.

Create the key

jenkins@e7b23bad10aa:/$ ssh-keygen

Press enter on all questions until you get the prompt back

Copy the key to your computer. From within the docker container your computer is 172.17.0.1 should you wonder.

jenkins@e7b23bad10aa:/$ ssh-copy-id [email protected]

user = your username and 172.17.0.1 is the ip address to your computer from within the docker container.

You will have to type your password at this point.

Now lets try to complete the loop by ssh-ing to your computer from within the docker container.

jenkins@e7b23bad10aa:/$ ssh [email protected]

This time you should not need to enter you password. If you do, something went wrong and you have to try again.

You will now be in your computers home folder. Try ls and have a look.

Do not stop here since we have a chain of ssh shells that we need to get out of.

$ exit
jenkins@e7b23bad10aa:/$ exit

Right! Now we are back and ready to continue.

Install your Jenkins

You will find your local Jenkins in your browser at http://localhost:8787.

First time you point your browser to your local Jenkins your will be greated with a Installation Wizard. Defaults are fine, do make sure you install the pipeline plugin during the setup though.

Setup your jenkins

It is very important that you activate matrix based security on http://localhost:8787/configureSecurity and give yourself all rights by adding yourself to the matrix and tick all the boxes. (There is a tick-all-boxes icon on the far right)

• Select Jenkins’ own user database as the Security Realm
• Select Matrix-based security in the Authorization section
• Write your username in the field User/group to add: and click on the [ Add ] button
• In the table above your username should pop up with a people icon next to it. If it is crossed over you typed your username incorrectly.
• Go to the far right of the table and click on the tick-all-button or manually tick all the boxes in your row.
• Please verify that the checkbox Prevent Cross Site Request Forgery exploits is unchecked. (Since this Jenkins is only reachable from your computer this isn't such a big deal)
• Click on [ Save ] and log out of Jenkins and in again just to make sure it works. If it doesn't you have to start over from the beginning and emptying the /opt/docker/jenkins/jenkins_home folder before restarting

Add the git user

We need to allow our git hook to login to our local Jenkins with minimal rights. Just to see and build jobs is sufficient. Therefore we create a user called git with password login.

Direct your browser to http://localhost:8787/securityRealm/addUser and add git as username and login as password. Click on [ Create User ].

Add the rights to the git user

Go to the http://localhost:8787/configureSecurity page in your browser. Add the git user to the matrix:

• Write git in the field User/group to add: and click on [ Add ]

Now it is time to check the boxes for minimal rights to the git user. Only these are needed:

• overall:read
• job:build
• job:discover
• job:read

Make sure that the Prevent Cross Site Request Forgery exploits checkbox is unchecked and click on [ Save ]

Create the pipeline project

We assume we have the username user and our git enabled project with the Jenkinsfile in it is called project and is located at /home/user/projects/project

In your http://localhost:8787 Jenkins add a new pipeline project. I named it hookpipeline for reference.

• Click on New Item in the Jenkins menu
• Name the project hookpipeline
• Click on Pipeline
• Click [ OK ]
• Tick the checkbox Poll SCM in the Build Triggers section. Leave the Schedule empty.
• In the Pipeline section:
  • select Pipeline script from SCM
  • in the Repository URL field enter [email protected]:projects/project/.git
  • in the Script Path field enter Jenkinsfile
• Save the hookpipeline project
• Build the hookpipeline manually once, this is needed for the Poll SCM to start working.

Create the git hook

Go to the /home/user/projects/project/.git/hooks folder and create a file called post-commit that contains this:

#!/bin/sh
BRANCHNAME=$(git rev-parse --abbrev-ref HEAD)
MASTERBRANCH='master'

curl -XPOST -u git:login http://localhost:8787/job/hookpipeline/build
echo "Build triggered successfully on branch: $BRANCHNAME"

Make this file executable:

$ chmod +x /home/user/projects/project/.git/hooks/post-commit

Test the post-commit hook:

$ /home/user/projects/project/.git/hooks/post-commit

Check in Jenkins if your hookpipeline project was triggered.

Finally make some arbitrary change to your project, add the changes and do a commit. This will now trigger the pipeline in your local Jenkins.

Happy Days!

I don't know about the full path, but you can use -R for recursion. Alternatively, if you're not bent on ls, you can just do find *.

Object assign copies one or more source objects to the target object. So we could use Object.assign here.

Syntax: Object.assign(target, ...sources)

var obj  = {};_x000D_
_x000D_
Object.assign(obj, {"1":"aa", "2":"bb"})_x000D_
_x000D_
console.log(obj)

I'm not sure if this works for you, but when I do small solo PHP projects with Eclipse, the first thing I set up is an Ant script for deploying the project to a remote testing environment. I code away locally, and whenever I want to test it, I just hit the shortcut which updates the remote site.

Eclipse has good Ant support out of the box, and the scripts aren't hard to make.

Just adding something to the Tung's answer (you need to use rstrip('/') to be more of the safer side if you're on a unix box).

>>> input = "../data/replies/"
>>> os.path.dirname(input.rstrip('/'))
'../data'
>>> input = "../data/replies"
>>> os.path.dirname(input.rstrip('/'))
'../data'

But, if you don't use rstrip('/'), given your input is

>>> input = "../data/replies/"

would output,

>>> os.path.dirname(input)
'../data/replies'

which is probably not what you're looking at as you want both "../data/replies/" and "../data/replies" to behave the same way.

You could use -sed- and -grep- to replace or write to the xml header of each file specifying your desired sheet name, e.g., sheetname1, between any occurrence of the tags:

<Sheetnames>?sheetname1?</Sheetnames>

You can do it this way also:

import pandas as pd
import os

new_df = pd.DataFrame()
for r, d, f in os.walk(csv_folder_path):
    for file in f:
        complete_file_path = csv_folder_path+file
        read_file = pd.read_csv(complete_file_path)
        new_df = new_df.append(read_file, ignore_index=True)

In my case, CSS did not fix the issue. I noticed the problem while using jQuery re-render a button.

$("#myButton").html("text")

Try this

$("#myButton").html("<span>text</span>")

You need to add the Servlet API to your classpath. In Tomcat 6.0, this is in a JAR called servlet-api.jar in Tomcat's lib folder. You can either add a reference to that JAR to the project's classpath, or put a copy of the JAR in your Eclipse project and add it to the classpath from there.

If you want to leave the JAR in Tomcat's lib folder:

• Right-click the project, click Properties.
• Choose Java Build Path.
• Click the Libraries tab
• Click Add External JARs...
• Browse to find servlet-api.jar and select it.
• Click OK to update the build path.

Or, if you copy the JAR into your project:

• Right-click the project, click Properties.
• Choose Java Build Path.
• Click Add JARs...
• Find servlet-api.jar in your project and select it.
• Click OK to update the build path.

I'm not about to repeat all the other answers, but there's one aspect that I haven't yet seen mentioned - it's the story of disappearing data. I don't know where to find it, but...

Basically it's about a web application that mysteriously every few night did loose all its data and nobody knew why. Inspecting the Logs later revealed that the site was found by google or another arbitrary spider, that happily GET (read: GOT) all the links it found on the site - including the "delete this entry" and "are you sure?" links.

Actually - part of this has been mentioned. This is the story behind "don't change data on GET but only on POST". Crawlers will happily follow GET, never POST. Even robots.txt doesn't help against misbehaving crawlers.

This should help you

        function(){
            if(flag == true){
                $('#region').append($('#mainmapplace .replace'));                
                $('#mainmapplace').children().remove();
                $('#mainmapplace').append($(originalmap));
                //$('#mapplace').append();
            }

CSS

#mainmapplace{
    width: 100px;
    height: 100px;
    background: red;

#region div{
    width: 100px;
    height: 100px;
    background: blue;
    margin: 10px 0 0 0;
}

I use this one:

LocationManager.requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener)

For example, using a 1s interval:

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);

the time is in milliseconds, the distance is in meters.

This automatically calls:

public void onLocationChanged(Location location) {
    //Code here, location.getAccuracy(), location.getLongitude() etc...
}

I also had these included in the script but didnt actually use them:

public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}

In short:

public class GPSClass implements LocationListener {

    public void onLocationChanged(Location location) {
        // Called when a new location is found by the network location provider.
        Log.i("Message: ","Location changed, " + location.getAccuracy() + " , " + location.getLatitude()+ "," + location.getLongitude());
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}
    public void onProviderEnabled(String provider) {}
    public void onProviderDisabled(String provider) {}

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
    }
}

Selenium answers this question in their DESCRIPTION.rst file:

Drivers
=======

Selenium requires a driver to interface with the chosen browser. Firefox, for example, requires geckodriver <https://github.com/mozilla/geckodriver/releases>_, which needs to be installed before the below examples can be run. Make sure it's in your PATH, e. g., place it in /usr/bin or /usr/local/bin.

Failure to observe this step will give you an error `selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

Basically just download the geckodriver, unpack it and move the executable to your /usr/bin folder.

you can use ast.literal_eval()

>>> import ast
>>> s = "{'username':'dfdsfdsf'}"
>>> ast.literal_eval(s)
{'username': 'dfdsfdsf'}

There's many forms of timeout, are you after the connection timeout, request timeout or time to live (time before TCP connection stops).

The default TimeToLive on Firefox is 115s (network.http.keep-alive.timeout)

The default connection timeout on Firefox is 250s (network.http.connection-retry-timeout)

The default request timeout for Firefox is 30s (network.http.pipelining.read-timeout).

The time it takes to do an HttpRequest depends on if a connection has been made this has to be within 250s which I'm guessing you're not after. You're probably after the request timeout which I think is 30,000ms (30s) so to conclude I'd say it's timing out with a connection time out that's why you got a response back after ~150s though I haven't really tested this.

You can use Windows Containers inside a virtual machine (the guest OS should match the requirements - Windows 10 Pro or Windows 2016).

For example you can use VirtualBox, just enable Hyper-V inside System / Acceleration / Paravirtualization Interface.

After that if Docker doesn't start up because of an error, use the "Switch to Windows containers..." in the settings.

(this could be moved as a comment to the accepted answer, but I don't have enough reputation to do so)

Besides the usages that JAiro mentioned, I like this one:

def getConnectionProps = {
    ( Config.getHost, Config.getPort, Config.getSommElse, Config.getSommElsePartTwo )
}

If someone needs all connection properties, he can do:

val ( host, port, sommEsle, someElsePartTwo ) = getConnectionProps

If you need just a host and a port, you can do:

val ( host, port, _, _ ) = getConnectionProps

If you know which colors you want, you can specify color properties in an array, like so:

    backgroundColor: [
    'rgba(75, 192, 192, 1)',
    ...
    ],
    borderColor: [
    'rgba(75, 192, 192, 1)',
    ...
    ],

static renders variable local to the file which is generally a good thing, see for example this Wikipedia entry.

yourList = ["a", "b", "a", "c", "c", "a", "c"]

expected outputs {a: 3, b: 1,c:3}

duplicateFrequencies = {}
for i in set(yourList):
    duplicateFrequencies[i] = yourList.count(i)

Cheers!! Reference

Yes, you can do print all keys using below bash script,

for key in $(redis-cli -p 6379 keys \*);
  do echo "Key : '$key'" 
     redis-cli -p 6379 GET $key;
done

where, 6379 is a port on which redis is running.

In case, it is a django backend application, you can do something like this.

docker exec -it container_id python manage.py dbshell

The query answered by sandip giri was the correct answer, here a similar example getting the maximum id (PresupuestoEtapaActividadHistoricoId), after calculate the maximum value(Base)

select * 
from (
    select PEAA.PresupuestoEtapaActividadId,
        PEAH.PresupuestoEtapaActividadHistoricoId,             
        sum(PEAA.ValorTotalDesperdicioBase) as Base,
        sum(PEAA.ValorTotalDesperdicioEjecucion) as Ejecucion
    from hgc.PresupuestoActividadAnalisis as PEAA
    inner join hgc.PresupuestoEtapaActividad as PEA
        on PEAA.PresupuestoEtapaActividadId = PEA.PresupuestoEtapaActividadId
    inner join hgc.PresupuestoEtapaActividadHistorico as PEAH
        on PEA.PresupuestoEtapaActividadId = PEAH.PresupuestoEtapaActividadId                                                         
    group by PEAH.PresupuestoEtapaActividadHistoricoId, PEAA.PresupuestoEtapaActividadId    
) as t
where exists (
    select 1 
    from (
        select MAX(PEAH.PresupuestoEtapaActividadHistoricoId) as PresupuestoEtapaActividadHistoricoId                                                                     
        from hgc.PresupuestoEtapaActividadHistorico as PEAH                       
        group by PEAH.PresupuestoEtapaActividadId  
    ) as ti
    where t.PresupuestoEtapaActividadHistoricoId = ti.PresupuestoEtapaActividadHistoricoId 
)

To link to a YouTube video so it plays in HD by default, use the following URL:

https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080

Change VIDEOID to the YouTube video ID that you want to link to. When someone follows the link, it will display the highest-resolution available (up to 1080p) in full-screen mode. Unfortunately, vq=hd1080 does not work on the normal YouTube site (with comments and related videos).

Your server is imposing some resource limit that your site is hitting. This is usually RAM, CPU, or INODES.

Ask your server administrator what the limits are and what it is you are hitting to solve.

In the iframe: So that means you have to add some code in the iframe page. Simply add this script to your code IN THE IFRAME:

<body onload="parent.alertsize(document.body.scrollHeight);">

In the holding page: In the page holding the iframe (in my case with ID="myiframe") add a small javascript:

<script>
function alertsize(pixels){
    pixels+=32;
    document.getElementById('myiframe').style.height=pixels+"px";
}
</script>

What happens now is that when the iframe is loaded it triggers a javascript in the parent window, which in this case is the page holding the iframe.

To that JavaScript function it sends how many pixels its (iframe) height is.

The parent window takes the number, adds 32 to it to avoid scrollbars, and sets the iframe height to the new number.

That's it, nothing else is needed.

But if you like to know some more small tricks keep on reading...

DYNAMIC HEIGHT IN THE IFRAME? If you like me like to toggle content the iframe height will change (without the page reloading and triggering the onload). I usually add a very simple toggle script I found online:

<script>
function toggle(obj) {
    var el = document.getElementById(obj);
    if ( el.style.display != 'block' ) el.style.display = 'block';
    else el.style.display = 'none';
}
</script>

to that script just add:

<script>
function toggle(obj) {
    var el = document.getElementById(obj);
    if ( el.style.display != 'block' ) el.style.display = 'block';
    else el.style.display = 'none';
    parent.alertsize(document.body.scrollHeight); // ADD THIS LINE!
}
</script>

How you use the above script is easy:

<a href="javascript:toggle('moreheight')">toggle height?</a><br />
<div style="display:none;" id="moreheight">
more height!<br />
more height!<br />
more height!<br />
</div>

For those that like to just cut and paste and go from there here is the two pages. In my case I had them in the same folder, but it should work cross domain too (I think...)

Demo

Like Snukker said, clients1.google.com is where the search suggestions come from. My guess is that they make a request to force clients1.google.com into your DNS cache before you need it, so you will have less latency on the first "real" request.

Google Chrome already does that for any links on a page, and (I think) when you type an address in the location bar. This seems like a way to get all browsers to do the same thing.

yum install gcc-c++

on aws ec2 (aws linux),it works

I'd use STUFF to insert dividing chars and then use CONVERT with the appropriate style. Something like this:

DECLARE @dt VARCHAR(100)='111290';
SELECT CONVERT(DATETIME,STUFF(STUFF(@dt,3,0,'/'),6,0,'/'),3)

First you use two times STUFF to get 11/12/90 instead of 111290, than you use the 3 to convert this to datetime (or any other fitting format: use . for german, - for british...) More details on CAST and CONVERT

Best was, to store date and time values properly.

• This should be either "universal unseparated format" yyyyMMdd
• or (especially within XML) it should be ISO8601: yyyy-MM-dd or yyyy-MM-ddThh:mm:ss More details on ISO8601

Any culture specific format will lead into troubles sooner or later...

There are multiple answers based on what you are doing with the string.

1) Using the string as an id (will not be modified). Passing it in by const reference is probably the best idea here: (std::string const&)

2) Modifying the string but not wanting the caller to see that change. Passing it in by value is preferable: (std::string)

3) Modifying the string but wanting the caller to see that change. Passing it in by reference is preferable: (std::string &)

4) Sending the string into the function and the caller of the function will never use the string again. Using move semantics might be an option (std::string &&)

I've your same requirements on a public API for which I used rails-api.

I've also set header in a before filter. It looks like this:

headers['Access-Control-Allow-Origin'] = '*'
headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
headers['Access-Control-Request-Method'] = '*'
headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'

It seems you missed the Access-Control-Request-Method header.

Far and away, the cleanest, easiest export from tables to Excel is Jquery DataTables Table Tools plugin. You get a grid that sorts, filters, orders, and pages your data, and with just a few extra lines of code and two small files included, you get export to Excel, PDF, CSV, to clipboard and to the printer.

This is all the code that's required:

  $(document).ready( function () {
    $('#example').dataTable( {
        "sDom": 'T<"clear">lfrtip',
        "oTableTools": {
            "sSwfPath": "/swf/copy_cvs_xls_pdf.swf"
        }
    } );
} );

So, quick to deploy, no browser limitations, no server-side language required, and most of all very EASY to understand. It's a win-win. The one thing it does have limits on, though, is strict formatting of columns.

If formatting and colors are absolute dealbreakers, the only 100% reliable, cross browser method I've found is to use a server-side language to process proper Excel files from your code. My solution of choice is PHPExcel It is the only one I've found so far that positively handles export with formatting to a MODERN version of Excel from any browser when you give it nothing but HTML. Let me clarify though, it's definitely not as easy as the first solution, and also is a bit of a resource hog. However, on the plus side it also can output direct to PDF as well. And, once you get it configured, it just works, every time.

UPDATE - September 15, 2016: TableTools has been discontinued in favor of a new plugin called "buttons" These tools perform the same functions as the old TableTools extension, but are FAR easier to install and they make use of HTML5 downloads for modern browsers, with the capability to fallback to the original Flash download for browsers that don't support the HTML5 standard. As you can see from the many comments since I posted this response in 2011, the main weakness of TableTools has been addressed. I still can't recommend DataTables enough for handling large amounts of data simply, both for the developer and the user.

Try to reinstall ADT plugin on Eclipse. Check out this: Installing the Eclipse Plugin

Supposing d is your list of dicts, simply:

df = pd.DataFrame(d)

Note: this does not work with nested data.

This answer is like rodrigob's except without the BOOST_FOREACH. You can use c++'s range based for instead.

#include <map>
#include <boost/range/adaptor/map.hpp>
#include <iostream>

template <typename K, typename V>
void printKeys(std::map<K,V> map){
     for(auto key : map | boost::adaptors::map_keys){
          std::cout << key << std::endl;
     }
}

Add annotation @Repository to the head of userDao Class.If userDao is a interface,add this annotation to the implements of the interface.

As Jage's answer removes the element completely, including event handlers and data, I'm adding a simple solution that doesn't do that, thanks to the detach function.

var element = $('#childNode').detach();
$('#parentNode').append(element);

Edit:

Igor Mukhin suggested an even shorter version in the comments below:

$("#childNode").detach().appendTo("#parentNode");

This is a BAD way to do it! I'm only leaving this answer in case it solves other weird problems. These better methods are the probably partly the result of newer data.table versions... so it's worth while to document this hard way. Plus, this is a nice syntax example for eval substitute syntax.

library(data.table)
dt <- data.table(ID = c(rep("A", 5), rep("B",5)), 
                 fac1 = c(1:5, 1:5), 
                 fac2 = c(1:5, 1:5) * 2, 
                 val1 = rnorm(10),
                 val2 = rnorm(10))

names_factors = c('fac1', 'fac2')
names_values = c('val1', 'val2')

for (col in names_factors){
  e = substitute(X := as.factor(X), list(X = as.symbol(col)))
  dt[ , eval(e)]
}
for (col in names_values){
  e = substitute(X := as.numeric(X), list(X = as.symbol(col)))
  dt[ , eval(e)]
}

str(dt)

which gives you

Classes ‘data.table’ and 'data.frame':  10 obs. of  5 variables:
 $ ID  : chr  "A" "A" "A" "A" ...
 $ fac1: Factor w/ 5 levels "1","2","3","4",..: 1 2 3 4 5 1 2 3 4 5
 $ fac2: Factor w/ 5 levels "2","4","6","8",..: 1 2 3 4 5 1 2 3 4 5
 $ val1: num  0.0459 2.0113 0.5186 -0.8348 -0.2185 ...
 $ val2: num  -0.0688 0.6544 0.267 -0.1322 -0.4893 ...
 - attr(*, ".internal.selfref")=<externalptr>

i just wrapped a div around them and made it align center. then you don't need any css on the buttons to center them.

<div class="buttonHolder">
  <input value="Search" title="Search" type="submit" id="btn_s"> 
  <input value="I'm Feeling Lucky" title="I'm Feeling Lucky" name="lucky" type="submit" id="btn_i">
</div>

.buttonHolder{ text-align: center; }

When you use float without width, there remains some space in that row. To block this space you can use clear:both; in next element.

Calling toDate will create a copy (the documentation is down-right wrong about it not being a copy), of the underlying JS Date object. JS Date object is stored in UTC and will always print to eastern time. Without getting into whether .utc() modifies the underlying object that moment wraps use the code below.

You don't need moment for this.

new Date().getTime()

This works, because JS Date at its core is in UTC from the Unix Epoch. It's extraordinarily confusing and I believe a big flaw in the interface to mix local and UTC times like this with no descriptions in the methods.

Java reverse an int value - Principles

1. Modding (%) the input int by 10 will extract off the rightmost digit. example: (1234 % 10) = 4

2. Multiplying an integer by 10 will "push it left" exposing a zero to the right of that number, example: (5 * 10) = 50

3. Dividing an integer by 10 will remove the rightmost digit. (75 / 10) = 7

Java reverse an int value - Pseudocode:

a. Extract off the rightmost digit of your input number. (1234 % 10) = 4

b. Take that digit (4) and add it into a new reversedNum.

c. Multiply reversedNum by 10 (4 * 10) = 40, this exposes a zero to the right of your (4).

d. Divide the input by 10, (removing the rightmost digit). (1234 / 10) = 123

e. Repeat at step a with 123

Java reverse an int value - Working code

public int reverseInt(int input) {
    long reversedNum = 0;
    long input_long = input;

    while (input_long != 0) {
        reversedNum = reversedNum * 10 + input_long % 10;
        input_long = input_long / 10;
    }

    if (reversedNum > Integer.MAX_VALUE || reversedNum < Integer.MIN_VALUE) {
        throw new IllegalArgumentException();
    }

You will never do anything like this in the real work-world. However, the process by which you use to solve it without help is what separates people who can solve problems from the ones who want to, but can't unless they are spoon fed by nice people on the blogoblags.

Is $target.remove(); what you're looking for?

If the IBM mainframe JCL has some extra characters or numbers at the end of the name of unix script being called then it can throw such error.

While it may or may not work in your situation, I have found it useful to generate a public / private key using Putty's Pageant.

If you are also working with bitbucket (.org) it should give you the ability to provide a public key to your user account and then commands that reach out to the repository will be secured automatically.

If Pageant doesn't start up for you upon a reboot, you can add a shortcut to Pageant to your Windows "Start menu" and the shortcut may need to have a 'properties' populated with the location of your private (.ppk) file.

With this in place Mercurial and your local repositories will need to be set up to push/pull using the SSH format.

Here are some detailed instructions on Atlassian's site for Windows OR Mac/Linux.

You don't have to take my word for it and there are no doubt other ways to do it. Perhaps these steps described here are more for you:

1. Start PuttyGen from Start -> PuTTY-> PuttyGen
2. Generate a new key and save it as a .ppk file without a passphrase
3. Use Putty to login to the server you want to connect to
4. Append the Public Key text from PuttyGen to the text of ~/.ssh/authorized_keys
5. Create a shortcut to your .ppk file from Start -> Putty to Start -> Startup
6. Select the .ppk shortcut from the Startup menu (this will happen automatically at every startup)
7. See the Pageant icon in the system tray? Right-click it and select “New session”
8. Enter username@hostname in the “Host name” field
9. You will now log in automatically.

You might need to re-adjust slightly on the widths and borders but that is a one shot to do.

Press " ? + Shift + A" on Mac (or "Ctrl+Shift+A" on Windows) and in the pop-up EditText, write "Sync Project with Gradle Files". After that double click on the appeared option. It will then sync your Gradle file SDK with the project file.

thanks for the answers. Read this article by Alex Rodriguez which suggests that a RESTful web service has 4 basic characteristics which are:

1. Use HTTP methods explicitly.
2. Be stateless.
3. Expose directory structure-like URIs.
4. Transfer XML, JavaScript Object Notation (JSON), or both.

// (rest of class implementation omitted)

@end

I also omitted the detailed information (e.g. "model A1507, A1516, A1526 (China), A1529 | Global") and placed it in the comments instead, in case you want to use this as user-facing strings and not freak them out.

Edit: This answer provides a similar implementation using Swift 2.

Edit 2: I just added the iPad Pro models (both sizes). For future reference, the model numbers/etc. can be found in The iPhone Wiki.

Edit 3: Add support for iPhone XS, iPhone XS Max and iPhone XR.

Edit 4: Add support for iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max.

The port for the Vue-cli webpack template is found in your app root's myApp/config/index.js.

All you have to do is modify the port value inside the dev block:

 dev: {
    proxyTable: {},
    env: require('./dev.env'),
    port: 4545,
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    cssSourceMap: false
  }

Now you can access your app with localhost:4545

also if you have .env file better to set it from there

If you use Hue, you can browse the table in the Metastore App and then click on 'View file location': that will open the HDFS File Browser in its directory.

I have created using following lines and this works for me.

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'

For AndroidX

implementation 'androidx.recyclerview:recyclerview:1.1.0'
implementation 'androidx.cardview:cardview:1.0.0'

Update with psycopg2 2.7:

The classic executemany() is about 60 times slower than @ant32 's implementation (called "folded") as explained in this thread: https://www.postgresql.org/message-id/20170130215151.GA7081%40deb76.aryehleib.com

This implementation was added to psycopg2 in version 2.7 and is called execute_values():

from psycopg2.extras import execute_values
execute_values(cur,
    "INSERT INTO test (id, v1, v2) VALUES %s",
    [(1, 2, 3), (4, 5, 6), (7, 8, 9)])

Previous Answer:

To insert multiple rows, using the multirow VALUES syntax with execute() is about 10x faster than using psycopg2 executemany(). Indeed, executemany() just runs many individual INSERT statements.

@ant32 's code works perfectly in Python 2. But in Python 3, cursor.mogrify() returns bytes, cursor.execute() takes either bytes or strings, and ','.join() expects str instance.

So in Python 3 you may need to modify @ant32 's code, by adding .decode('utf-8'):

args_str = ','.join(cur.mogrify("(%s,%s,%s,%s,%s,%s,%s,%s,%s)", x).decode('utf-8') for x in tup)
cur.execute("INSERT INTO table VALUES " + args_str)

Or by using bytes (with b'' or b"") only:

args_bytes = b','.join(cur.mogrify("(%s,%s,%s,%s,%s,%s,%s,%s,%s)", x) for x in tup)
cur.execute(b"INSERT INTO table VALUES " + args_bytes) 

for (int i = 0; i < getArray.length(); i++) {
            JSONObject objects = getArray.getJSONObject(i);
            Iterator key = objects.keys();
            while (key.hasNext()) {
                String k = key.next().toString();
                System.out.println("Key : " + k + ", value : "
                        + objects.getString(k));
            }
            // System.out.println(objects.toString());
            System.out.println("-----------");

        }

Hope this helps someone

sql fiddle demo

The input date value format needs the date specified as per http://tools.ietf.org/html/rfc3339#section-5.6 full-date.

So I've ended up doing:

<input type="date" id="last-start-date" value="@string.Format("{0:yyyy-MM-dd}", Model.LastStartDate)" />

I did try doing it "properly" using:

[DataType(DataType.Date)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
public DateTime LastStartDate
{
    get { return lastStartDate; }
    set { lastStartDate = value; }
}

with

@Html.TextBoxFor(model => model.LastStartDate, 
    new { type = "date" })

Unfortunately that always seemed to set the value attribute of the input to a standard date time so I've ended up applying the formatting directly as above.

Edit:

According to Jorn if you use

@Html.EditorFor(model => model.LastStartDate)

instead of TextBoxFor it all works fine.

Fresh answer 2018:

Step 1 Launch Microsoft Paint. Not Paint.Net but plain Paint

Step 2 Open the image you want to convert to icon format by clicking the “Paint” toolbar tab and selecting “Open.”

Step 3 Click the “Paint” tab, highlight the “Save As” option and select the “BMP picture” option. As 256-colored. There is a dropdown list.

Step 4 You have to open it in Paint.net now. Enter a file name for the icon and type “.ico” (without quotations) as the file extension. Select your preferred output folder for the icon and click “Save.”(still in bmp type) , exposing auto definition in saving parameters window.

This is a solution for those WHO DOESN'T WANT THE THIRD PARTY APPS TO GAIN PERMISSIONS ON THEIR COMP.
I use this simple way to create custom icons for folders on my desktop or documents.

Try:

g = pd.DataFrame(['A','B','A','C','D','D','E'])

# Group by the contents of column 0 
gg = g.groupby(0)  

# Create a DataFrame with the counts of each letter
histo = gg.apply(lambda x: x.count())

# Add a new column that is the count / total number of elements    
histo[1] = histo.astype(np.float)/len(g) 

print histo

Output:

   0         1
0             
A  2  0.285714
B  1  0.142857
C  1  0.142857
D  2  0.285714
E  1  0.142857

Alex, Gary:

As requested, here is my comment posted as an answer:

var rt = ($(window).width() - ($whatever.offset().left + $whatever.outerWidth()));

Thanks for letting me know.

In pseudo code that can be expressed as:

The right offset is:

The window's width MINUS
( The element's left offset PLUS the element's outer width )

You can just add the DISTINCT(ip), but it has to come at the start of the query. Be sure to escape PHP variables that go into the SQL string.

SELECT DISTINCT(ip), name, COUNT(name) nameCnt, 
time, price, SUM(price) priceSum
FROM tablename 
WHERE time >= $yesterday AND time <$today 
GROUP BY ip, name

Use below code to generate files on fly..

<? //Generate text file on the fly

   header("Content-type: text/plain");
   header("Content-Disposition: attachment; filename=savethis.txt");

   // do your Db stuff here to get the content into $content
   print "This is some text...\n";
   print $content;
 ?>

you can store it in array and then use whichever line you want.. this is the code snippet that i have used to read line from file and store it in a string array, hope this will be useful for you :)

public class user {
 public static void main(String x[]) throws IOException{
  BufferedReader b=new BufferedReader(new FileReader("<path to file>"));
  String[] user=new String[30];
  String line="";
  while ((line = b.readLine()) != null) {
   user[i]=line; 
   System.out.println(user[1]);
   i++;  
   }

 }
}

There isn't an easy way like listview.addHeaderView() but you can achieve this by adding a type to your adapter for header.

Here is an example

public class HeaderAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private static final int TYPE_HEADER = 0;
    private static final int TYPE_ITEM = 1;
    String[] data;

    public HeaderAdapter(String[] data) {
        this.data = data;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        if (viewType == TYPE_ITEM) {
            //inflate your layout and pass it to view holder
            return new VHItem(null);
        } else if (viewType == TYPE_HEADER) {
            //inflate your layout and pass it to view holder
            return new VHHeader(null);
        }

        throw new RuntimeException("there is no type that matches the type " + viewType + " + make sure your using types correctly");

A small improvement on the reduce usage:

var arr = [
    { key: 'foo', val: 'bar' },
    { key: 'hello', val: 'world' }
];

var result = arr.reduce((map, obj) => ({
    ...map,
    [obj.key] = obj.val
}), {});

console.log(result);
// { foo: 'bar', hello: 'world' }

Python 3

from urllib.error import HTTPError

Python 2

from urllib2 import HTTPError

Just catch HTTPError, handle it, and if it's not Error 404, simply use raise to re-raise the exception.

See the Python tutorial.

e.g. complete example for Pyhton 2

import urllib2
from urllib2 import HTTPError
try:
   urllib2.urlopen("some url")
except HTTPError as err:
   if err.code == 404:
       <whatever>
   else:
       raise

You can use the following script, just replace DOMAIN with the name of your domain. When executed it will prompt you for a userlogin then hide that user's account from the address lists.

$name=Read-Host "Enter login name of user to hide"
Set-Mailbox -Identity DOMAIN\$name -HiddenFromAddressListsEnabled $true

I had to tweak the Chrome launcher on macosx and added below script. Saved it as below;

/Applications/Google\ Chrome.app/Contents/MacOS/Chrome.command

#!/bin/sh
RealBin="Google Chrome"
AppDir="$(dirname "$0")"
exec "$AppDir/$RealBin" --ignore-certificate-errors "$@"

When I start Chrome with this script self-signed certificates are working without a problem. But don't browse the web with the browser launched with this script you will not be warned about invalid certificates!

Or if you want to have your own implementation, I wrote this quick function as an example:

/**
 * hex2int
 * take a hex string and convert it to a 32bit number (max 8 hex digits)
 */
uint32_t hex2int(char *hex) {
    uint32_t val = 0;
    while (*hex) {
        // get current character then increment
        uint8_t byte = *hex++; 
        // transform hex character to the 4bit equivalent number, using the ascii table indexes
        if (byte >= '0' && byte <= '9') byte = byte - '0';
        else if (byte >= 'a' && byte <='f') byte = byte - 'a' + 10;
        else if (byte >= 'A' && byte <='F') byte = byte - 'A' + 10;    
        // shift 4 to make space for new digit, and add the 4 bits of the new digit 
        val = (val << 4) | (byte & 0xF);
    }
    return val;
}

I also got this type error, problem is wrong usage of parameters to statement like, Let's say you have a query like this

SELECT * FROM EMPLOYE E WHERE E.ID = ?

and for the preparedStatement object (JDBC) if you set the parameters like

preparedStatement.setXXX(1,value);
preparedStatement.setXXX(2,value)

then it results in SQLException: Invalid column index

So, I removed that second parameter setting to prepared statement then problem solved

It sounds like you're trying to link with your resulting object file with gcc instead of g++:

Note that programs using C++ object files must always be linked with g++, in order to supply the appropriate C++ libraries. Attempting to link a C++ object file with the C compiler gcc will cause "undefined reference" errors for C++ standard library functions:

$ g++ -Wall -c hello.cc
$ gcc hello.o       (should use g++)
hello.o: In function `main':
hello.o(.text+0x1b): undefined reference to `std::cout'
.....
hello.o(.eh_frame+0x11):
  undefined reference to `__gxx_personality_v0'

Each controller has it's own scope(s) so that's causing your issue.

Having two controllers that want access to the same data is a classic sign that you want a service. The angular team recommends thin controllers that are just glue between views and services. And specifically- "services should hold shared state across controllers".

Happily, there's a nice 15-minute video describing exactly this (controller communication via services): video

One of the original author's of Angular, Misko Hevery, discusses this recommendation (of using services in this situation) in his talk entitled Angular Best Practices (skip to 28:08 for this topic, although I very highly recommended watching the whole talk).

You can use events, but they are designed just for communication between two parties that want to be decoupled. In the above video, Misko notes how they can make your app more fragile. "Most of the time injecting services and doing direct communication is preferred and more robust". (Check out the above link starting at 53:37 to hear him talk about this)

You found the shorthand to set privileges for all existing tables in the given schema. The manual clarifies:

(but note that ALL TABLES is considered to include views and foreign tables).

Bold emphasis mine. serial columns are implemented with nextval() on a sequence as column default and, quoting the manual:

For sequences, this privilege allows the use of the currval and nextval functions.

So if there are serial columns, you'll also want to grant USAGE (or ALL PRIVILEGES) on sequences

GRANT USAGE ON ALL SEQUENCES IN SCHEMA foo TO mygrp;

Note: identity columns in Postgres 10 or later use implicit sequences that don't require additional privileges. (Consider upgrading serial columns.)

What about new objects?

You'll also be interested in DEFAULT PRIVILEGES for users or schemas:

ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT ALL PRIVILEGES ON TABLES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT USAGE          ON SEQUENCES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo REVOKE ...;

This sets privileges for objects created in the future automatically - but not for pre-existing objects.

Default privileges are only applied to objects created by the targeted user (FOR ROLE my_creating_role). If that clause is omitted, it defaults to the current user executing ALTER DEFAULT PRIVILEGES. To be explicit:

ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo GRANT ...;
ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo REVOKE ...;

Note also that all versions of pgAdmin III have a subtle bug and display default privileges in the SQL pane, even if they do not apply to the current role. Be sure to adjust the FOR ROLE clause manually when copying the SQL script.

You could query an LDAP server from the command line with ldap-utils: ldapsearch, ldapadd, ldapmodify

The error you mentioned happens when you have two versions of NumPy on your system. As you mentioned, the version of NumPy you imported is still not upgraded since you tried to upgrade it through pip (it will upgrade the version existing in '/Library/Python/2.7/site-packages' ).

However Python still loads the packages from '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy' where the pre-installed packages live.

In order to upgrade that version you have to use easy_install. The other way around this problem is using virtualenv and setting up a new environment with all the requirements you need.

Or take the .not() method

https://api.jquery.com/not/

$(".thisClass").not("#thisId").doAction();

Add the following to the header:

<script language="javascript" type="text/javascript">
function limitText(limitField, limitNum) {
    if (limitField.value.length > limitNum) {
        limitField.value = limitField.value.substring(0, limitNum);
    }
}
</script>

    <input type="text" id="sessionNo" name="sessionNum" onKeyDown="limitText(this,5);" 
onKeyUp="limitText(this,5);"" />

The most common reason could be the database connection string. You have to change the connection string attachDBFile=|DataDirectory|file_name.mdf. there might be problem in host name which would be (local),localhost or .\sqlexpress.

You can use element.getBoundingClientRect() to retrieve element position relative to the viewport.

Then use document.documentElement.scrollTop to calculate the viewport offset.

The sum of the two will give the element position relative to the document:

element.getBoundingClientRect().top + document.documentElement.scrollTop

It'll be good to see the csv file itself, but this might work for you, give it a try, replace:

file_read = csv.reader(self.file)

with:

file_read = csv.reader(self.file, dialect=csv.excel_tab)

Or, open a file with universal newline mode and pass it to csv.reader, like:

reader = csv.reader(open(self.file, 'rU'), dialect=csv.excel_tab)

Or, use splitlines(), like this:

def read_file(self):
    with open(self.file, 'r') as f:
        data = [row for row in csv.reader(f.read().splitlines())]
    return data

Using the request module solved the issue.

// Include the request library for Node.js   
var request = require('request');
//  Basic Authentication credentials   
var username = "vinod"; 
var password = "12345";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(   
{
url : "https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school",
headers : { "Authorization" : authenticationHeader }  
},
 function (error, response, body) {
 console.log(body); }  );         

As mentioned in a different post Read .txt file from workspace groovy script in Jenkins I was struggling to make it work for the pom modules for a file in the workspace, in the Extended Choice Parameter. Here is my solution with the printlns:

import groovy.util.XmlSlurper
import java.util.Map
import jenkins.*
import jenkins.model.*
import hudson.*
import hudson.model.*    

try{
//get Jenkins instance
    def jenkins = Jenkins.instance
//get job Item
    def item = jenkins.getItemByFullName("The_JOB_NAME")
    println item
// get workspacePath for the job Item
    def workspacePath = jenkins.getWorkspaceFor (item)
    println workspacePath

    def file = new File(workspacePath.toString()+"\\pom.xml")
    def pomFile = new XmlSlurper().parse(file)
    def pomModules = pomFile.modules.children().join(",")
    return pomModules
} catch (Exception ex){
    println ex.message
}

Here are some other reasons to consider:

1. structs get an automatic initializer that you don't have to maintain in code at all.

   struct MorphProperty {
      var type : MorphPropertyValueType
      var key : String
      var value : AnyObject
   
      enum MorphPropertyValueType {
          case String, Int, Double
      }
    }
   
    var m = MorphProperty(type: .Int, key: "what", value: "blah")
   

To get this in a class, you would have to add the initializer, and maintain the intializer...

2. Basic collection types like Array are structs. The more you use them in your own code, the more you will get used to passing by value as opposed to reference. For instance:

   func removeLast(var array:[String]) {
      array.removeLast()
      println(array) // [one, two]
   }
   
   var someArray = ["one", "two", "three"]
   removeLast(someArray)
   println(someArray) // [one, two, three]
   

3. Apparently immutability vs. mutability is a huge topic, but a lot of smart folks think immutability -- structs in this case -- is preferable. Mutable vs immutable objects

If you're looking for reflection of all properties, the answers above are great.

If you're simply looking to get the keys of a dictionary (which is different from an 'object' in Python), use

my_dict.keys()

my_dict = {'abc': {}, 'def': 12, 'ghi': 'string' }
my_dict.keys() 
> ['abc', 'def', 'ghi']

Append IDs at the class declaration

.aclass, #hashone, #hashtwo{ ...codes... }
document.getElementById( "hashone" ).style.visibility = "hidden";

The challenge I see with the solution:

FROM( 
SELECT top(100) *
    FROM Customers 
UNION
    SELECT top(100) *  
    FROM CustomerEurope 
UNION 
    SELECT top(100) *  
    FROM CustomerAsia 
UNION
    SELECT top(100) *  
    FROM CustomerAmericas
)

is that this creates a windowed data set that will reside in the RAM and on larger data sets this solution will create severe performance issues as it must first create the partition and then it will use the partition to write to the temp table.

A better solution would be the following:

SELECT top(100)* into #tmpFerdeen
FROM Customers

Insert into #tmpFerdeen
SELECT top(100)* 
FROM CustomerEurope

Insert into #tmpFerdeen
SELECT top(100)* 
FROM CustomerAsia

Insert into #tmpFerdeen
SELECT top(100)* 
FROM CustomerAmericas

to select insert into the temp table and then add additional rows. However the draw back here is if there are any duplicate rows in the data.

The Best Solution would be the following:

Insert into #tmpFerdeen
SELECT top(100)* 
FROM Customers
UNION
SELECT top(100)* 
FROM CustomerEurope
UNION
SELECT top(100)* 
FROM CustomerAsia
UNION
SELECT top(100)* 
FROM CustomerAmericas

This method should work for all purposes that require distinct rows. If, however, you want the duplicate rows simply swap out the UNION for UNION ALL

Best of luck!

template <typename T>
void remove(std::vector<T>& vec, size_t pos)
{
    std::vector<T>::iterator it = vec.begin();
    std::advance(it, pos);
    vec.erase(it);
}

Try the following:

df[df['Col2'].isnull()]

We did it like this:

from p in Products                         
join bp in BaseProducts on p.BaseProductId equals bp.Id                    
where !string.IsNullOrEmpty(p.SomeId) && p.LastPublished >= lastDate                         
group new { p, bp } by new { p.SomeId } into pg    
let firstproductgroup = pg.FirstOrDefault()
let product = firstproductgroup.p
let baseproduct = firstproductgroup.bp
let minprice = pg.Min(m => m.p.Price)
let maxprice = pg.Max(m => m.p.Price)
select new ProductPriceMinMax
{
SomeId = product.SomeId,
BaseProductName = baseproduct.Name,
CountryCode = product.CountryCode,
MinPrice = minprice, 
MaxPrice = maxprice
};

EDIT: we used the version of AakashM, because it has better performance

I've made a mistake in the last my post. This is working example for how to pass additional argument in callback function:

function custom_func(p1,p2) {
    $.post(AJAX_FILE_PATH,{op:'dosomething',p1:p1},
        function(data){
            return function(){
                alert(data);
                alert(p2);
            }(data,p2)
        }
    );
    return false;
}

If you want to know when home is clicked is an AppCompatActivity then you should try it like this:

First tell Android you want to use your Toolbar as your ActionBar:

setSupportActionBar(toolbar);

Then set Home to be displayed via setDisplayShowHomeEnabled like this:

getSupportActionBar().setDisplayShowHomeEnabled(true);

Finally listen for click events on android.R.id.home like usual:

@Override
public boolean onOptionsItemSelected(MenuItem menuItem) {
    if (menuItem.getItemId() == android.R.id.home) {
        Timber.d("Home pressed");
    }
    return super.onOptionsItemSelected(menuItem);
}

If you want to know when the navigation button is clicked on a Toolbar in a class other than AppCompatActivity you can use these methods to set a navigation icon and listen for click events on it. The navigation icon will appear on the left side of your Toolbar where the the "home" button used to be.

toolbar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_nav_back));
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Log.d("cek", "home selected");
    }
});

If you want to know when the hamburger is clicked and when the drawer opens, you're already listening for these events via onDrawerOpened and onDrawerClosed so you'll want to see if those callbacks fit your requirements.

An answer above got me 99% of the way there (thanks Denis Ivin!). For my PHP / MySQL implementation, I needed to change the syntax a little:

SELECT *
FROM UserProfile
WHERE PropertydefinitionID in (40, 53)
AND (LENGTH(IFNULL(PropertyValue,'')) = 0)

LEN becomes LENGTH and ISNULL becomes IFNULL.

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

This works in Python 2 and Python 3:

A random key:

random.choice(list(d.keys()))

A random value

random.choice(list(d.values()))

A random key and value

random.choice(list(d.items()))

It's called the Big O notation, and describes the search time for various algorithms.

O(1) means that the worst case run time is constant. For most situation it means that you dont acctually need to search the collection, you cand find what you are searching for right away.

You should add next permission:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

And then here is usages in code:

val externalFilesDir = context.getExternalFilesDir(DIRECTORY_DOWNLOADS)

As of 2020, using ContentResult is still the right approach as proposed above, but the usage is as follows:

return new System.Web.Mvc.ContentResult
{
    Content = "Hi there! ?",
    ContentType = "text/plain; charset=utf-8"
}

usort($array, 'my_sort_function');

var_dump($array);

function my_sort_function($a, $b)
{
    return $a->name < $b->name;
}

The same code will be with the count field.

More details about usort: http://ru2.php.net/usort

Btw, where did you get that array from? I hope that not from database?

You can use js2py context to execute your js code and get output from document.write with mock document object:

import js2py

js = """
var output;
document = {
    write: function(value){
        output = value;
    }
}
""" + your_script

context = js2py.EvalJs()
context.execute(js)
print(context.output)

You can set your username for all repositories at a given site by putting something like the following in your Git configuration file. You'll want to change "https://example.com" and "me" to the actual URL and your actual username.

[credential "https://example.com"]
    username = me

(This is directly from "git help credentials")

Avoid using Xcode to rename files in a folder reference. If you rename a file using Xcode, it will be marked for commit. If you later delete it before the commit, you will end up with this error.

Since you're using requests, you should use the response's json method.

import requests

response = requests.get(...)
data = response.json()

It autodetects which decoder to use.

You need to add 2 methods, note __hash__ and __eq__:

class MyThing:
    def __init__(self,name,location,length):
        self.name = name
        self.location = location
        self.length = length

    def __hash__(self):
        return hash((self.name, self.location))

    def __eq__(self, other):
        return (self.name, self.location) == (other.name, other.location)

    def __ne__(self, other):
        # Not strictly necessary, but to avoid having both x==y and x!=y
        # True at the same time
        return not(self == other)

The Python dict documentation defines these requirements on key objects, i.e. they must be hashable.

If it helps anyone, I was having an issue where I wanted to treat an object as another type with a similar interface. I attempted the following:

Didn't pass linting

const x = new Obj(a as b);

The linter was complaining that a was missing properties that existed on b. In other words, a had some properties and methods of b, but not all. To work around this, I followed VS Code's suggestion:

Passed linting and testing

const x = new Obj(a as unknown as b);

Note that if your code attempts to call one of the properties that exists on type b that is not implemented on type a, you should realize a runtime fault.

Seekbar called onProgressChanged method when we initialize first time. We can skip by using below code We need to check boolean it return false when initialize automatically

volumeManager.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
                if(b){
                    mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, i, 0);
                }
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
        });

Here's a minor update with new models:

- (NSString *) platformString{
    NSString *platform = [self platform];
    if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";
    if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
    if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";
    if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
    if ([platform isEqualToString:@"iPod1,1"])   return @"iPod Touch 1G";
    if ([platform isEqualToString:@"iPod2,1"])   return @"iPod Touch 2G";
    if ([platform isEqualToString:@"iPod3,1"])   return @"iPod Touch 3G";
    if ([platform isEqualToString:@"i386"])   return @"iPhone Simulator";
    return platform;
}

As Dan pointed out, even once you normalize for clock frequency (which can be misleading in itself in pipelined designs), results will vary wildly based on CPU architecture (individual ALU/FPU performance, as well as actual number of ALUs/FPUs available per core in superscalar designs which influences how many independent operations can execute in parallel -- the latter factor is not exercised by the code below as all operations below are sequentially dependent.)

Why is Ruby considered slow?

Because if you run typical benchmarks between Ruby and other languages, Ruby loses.

I do not find Ruby to be slow but then again, I'm just using it to make simple CRUD apps and company blogs. What sort of projects would I need to be doing before I find Ruby becoming slow? Or is this slowness just something that affects all programming languages?

Ruby probably wouldn't serve you well in writing a real-time digital signal processing application, or any kind of real-time control system. Ruby (with today's VMs) would probably choke on a resource-constrained computer such as smartphones.

Remember that a lot of the processing on your web applications is actually done by software developed in C. e.g. Apache, Thin, Nginx, SQLite, MySQL, PostgreSQL, many parsing libraries, RMagick, TCP/IP, etc are C programs used by Ruby. Ruby provides the glue and the business logic.

What are your options as a Ruby programmer if you want to deal with this "slowness"?

Switch to a faster language. But that carries a cost. It is a cost that may be worth it. But for most web applications, language choice is not a relevant factor because there is just not enough traffic justify using a faster language that costs much more to develop for.

Which version of Ruby would best suit an application like Stack Overflow where speed is critical and traffic is intense?

Other folks have answered this - JRuby, IronRuby, REE will make the Ruby part of your application run faster on platforms that can afford the VMs. And since it is often not Ruby that causes slowness, but your computer system architecture and application architecture, you can do stuff like database replication, multiple application servers, loadbalancing with reverse proxies, HTTP caching, memcache, Ajax, client-side caching, etc. None of this stuff is Ruby.

Finally, I can't find much news on Ruby 2.0 - I take it we're a good few years away from that then?

Most folks are waiting for Ruby 1.9.1. I myself am waiting for Rails 3.1 on Ruby 1.9.1 on JRuby.

Finally, please remember that a lot of developers choose Ruby because it makes programming a more joyful experience compared to other languages, and because Ruby with Rails enables skilled web developers to develop applications very quickly.

For Win Forms :

To get the value (assuming that you want the value, not the text) out of a radio button, you get the Checked property:

string value = "";
bool isChecked = radioButton1.Checked;
if(isChecked )
  value=radioButton1.Text;
else
  value=radioButton2.Text;

For Web Forms :

<asp:RadioButtonList ID="rdoPriceRange" runat="server" RepeatLayout="Flow">
    <asp:ListItem Value="Male">Male</asp:ListItem>
    <asp:ListItem Value="Female">Female</asp:ListItem>
</asp:RadioButtonList>

And CS-in some button click

string value=rdoPriceRange.SelectedItem.Value.ToString();

rdougan's post did not work for me but it was a good starting point for my solution.

function androidSoftKeyHideFix(selectorName){
    $(selectorName).on('focus', function (event) {
        $(selectorName).off('focus')
        $('body').on('touchend', function (event) {
            $('body').off('touchend')
            $('.blurBox').focus();
            setTimeout(function() {
                $('.blurBox').blur();
                $('.blurBox').focus();
                $('.blurBox').blur();
                androidSoftKeyHideFix(selectorName); 
            },1)
        });
    });
}    

You need an input element at the top of the body, I classed as 'blurBox'. It must not be display:none. So give it opacity:0, and position:absolute. I tried placing it at the bottom of the body and it didn't work.

I found it necessary to repeat the .focus() .blur() sequence on the blurBox. I tried it without and it doesn't work.

This works on my 2.3 Android. I imagine that custom keyboard apps could still have issues.

I encountered a number of issues before arriving at this. There was a bizarre issue with subsequent focuses retriggering a blur/focus, which seemed like an android bug. I used a touchend listener instead of a blur listener to get around the function refiring closing the keyboard immediately after a non-initial opening. I also had an issue with keyboard typing making the scroll jump around...which is realted to a 3d transform used on a parent. That emerged from an attempt to workaround the blur-refiring issue, where I didn't unblur the blurBox at the end. So this is a delicate solution.

In my case,

1. Giving a static width to the modal hurts the responsiveness.
2. The modal-lg class was not wide enough.

so the solution was

@media (min-width: 1200px) {
   .modal-xlg {
      width: 90%; 
   }
}

and use the above class instead of modal-lg class

I got the same error message (Couldn't find developer disk image) after I updated my devices to iOS 9.2, but forgot to update to Xcode 7.2.

So in my case, the fix was easy: just update to Xcode 7.2 via Mac App Store.

nonatomic/atomic

• nonatomic is much faster than atomic
• always use nonatomic unless you have a very specific requirement for atomic, which should be rare (atomic doesn't guarantee thread safety - only stalls accessing the property when it's simultaneously being set by another thread)

strong/weak/assign

• use strong to retain objects - although the keyword retain is synonymous, it's best to use strong instead
• use weak if you only want a pointer to the object without retaining it - useful for avoid retain cycles (ie. delegates) - it will automatically nil out the pointer when the object is released
• use assign for primatives - exactly like weak except it doesn't nil out the object when released (set by default)

(Optional)

copy

• use it for creating a shallow copy of the object
• good practice to always set immutable properties to copy - because mutable versions can be passed into immutable properties, copy will ensure that you'll always be dealing with an immutable object
• if an immutable object is passed in, it will retain it - if a mutable object is passed in, it will copy it

readonly

• use it to disable setting of the property (prevents code from compiling if there's an infraction)
• you can change what's delivered by the getter by either changing the variable directly via its instance variable, or within the getter method itself

Based on tips from https://developer.mozilla.org/en-US/docs/CSS/background-size I end up with the following recipe that worked for me

body {
        overflow-y: hidden ! important;
        overflow-x: hidden ! important;
        background-color: #f8f8f8;
        background-image: url('index.png');
        /*background-size: cover;*/
        background-size: contain;
        background-repeat: no-repeat;
        background-position: right;
}

We have used both and we like Bootstrap for its simplicity and the pace at which it's being developed and enhanced. The problem with jQuery UI is that it's moving at a snail's pace. It's taking years to roll out common features like Menubar, Tree control and DataGrid which are in planning/development stage for ever. We waited waited waited and finally given up and used other libraries like ExtJS for our product http://dblite.com.

Bootstrap has come up with quite a comprehensive set of features in a very short period of time and I am sure it will outpace jQuery UI pretty soon.

So I see no point in using something that will eventually be outdated...

Even though I realise this is an old question, I'd like to suggest using the traceback module to handle output of the exceptions.

Use traceback.print_exc() to print the current exception to standard error, just like it would be printed if it remained uncaught, or traceback.format_exc() to get the same output as a string. You can pass various arguments to either of those functions if you want to limit the output, or redirect the printing to a file-like object.

Harish has the answer here - except you need to request manage_pages permission when authenticating and then using the page-id instead of me when posting....

I can use \s outside of collections but have to use [:space:] inside of collections. In fact I can use [:space:] only inside collections. So to match a single space using this I have to use [[:space:]] Which is really strange.

echo a b cX | sed -r "s/(a\sb[[:space:]]c[^[:space:]])/Result: \1/"

Result: a b cX

• first space I match with \s
• second space I match alternatively with [[:space:]]
• the X I match with "all but no space" [^[:space:]]

These two will not work:

a[:space:]b  instead use a\sb or a[[:space:]]b

a[^\s]b      instead use a[^[:space:]]b

The following seemed to work well for me:

=DATEDIF(B2, Today(), "D")

Strong typing probably means that variables have a well-defined type and that there are strict rules about combining variables of different types in expressions. For example, if A is an integer and B is a float, then the strict rule about A+B might be that A is cast to a float and the result returned as a float. If A is an integer and B is a string, then the strict rule might be that A+B is not valid.

Static typing probably means that types are assigned at compile time (or its equivalent for non-compiled languages) and cannot change during program execution.

Note that these classifications are not mutually exclusive, indeed I would expect them to occur together frequently. Many strongly-typed languages are also statically-typed.

And note that when I use the word 'probably' it is because there are no universally accepted definitions of these terms. As you will already have seen from the answers so far.

I took some help from MSDN, but this is my answer:

double number;
string localStringNumber;
string doubleNumericValueasString = "65.89875";
System.Globalization.NumberStyles style = System.Globalization.NumberStyles.AllowDecimalPoint;

if (double.TryParse(doubleNumericValueasString, style, System.Globalization.CultureInfo.InvariantCulture, out number))
    Console.WriteLine("Converted '{0}' to {1}.", doubleNumericValueasString, number);
else
    Console.WriteLine("Unable to convert '{0}'.", doubleNumericValueasString);
localStringNumber =number.ToString(System.Globalization.CultureInfo.CreateSpecificCulture("de-DE"));

You can see for yourself which is better between - List Comprehension and the Map Function

(List Comprehension takes lesser time to process 1 million records when compared to a map function)

Hope it helps! Good Luck :)

I don't think you can in a self-contained service (when you call Restart, it will stop the service, which will interrupt the Restart command, and it won't ever get started again). If you can add a second .exe (a Console app that uses the ServiceManager class), then you can kick off the standalone .exe and have it restart the service and then exit.

On second thought, you could probably have the service register a Scheduled Task (using the command-line 'at' command, for example) to start the service and then have it stop itself; that would probably work.

This code snippet can helped:

    final InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
    if (inputMethodManager != null && inputMethodManager.isActive()) {
        if (getCurrentFocus() != null) {
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }
    }

It can be called in different methods according to need (ex. onPause, onResume, onRestart ...)

The default behavior is:

1. If the parameter is a primitive type (int, bool, double, ...), Web API tries to get the value from the URI of the HTTP request.

2. For complex types (your own object, for example: Person), Web API tries to read the value from the body of the HTTP request.

So, if you have:

• a primitive type in the URI, or
• a complex type in the body

...then you don't have to add any attributes (neither [FromBody] nor [FromUri]).

But, if you have a primitive type in the body, then you have to add [FromBody] in front of your primitive type parameter in your WebAPI controller method. (Because, by default, WebAPI is looking for primitive types in the URI of the HTTP request.)

Or, if you have a complex type in your URI, then you must add [FromUri]. (Because, by default, WebAPI is looking for complex types in the body of the HTTP request by default.)

Primitive types:

public class UsersController : ApiController
{
    // api/users
    public HttpResponseMessage Post([FromBody]int id)
    {

    }
    // api/users/id
    public HttpResponseMessage Post(int id)
    {

    }       
}

Complex types:

public class UsersController : ApiController
{       
    // api/users
    public HttpResponseMessage Post(User user)
    {

    }

    // api/users/user
    public HttpResponseMessage Post([FromUri]User user)
    {

    }       
}

This works as long as you send only one parameter in your HTTP request. When sending multiple, you need to create a custom model which has all your parameters like this:

public class MyModel
{
    public string MyProperty { get; set; }
    public string MyProperty2 { get; set; }
}

[Route("search")]
[HttpPost]
public async Task<dynamic> Search([FromBody] MyModel model)
{
    // model.MyProperty;
    // model.MyProperty2;
}

From Microsoft's documentation for parameter binding in ASP.NET Web API:

When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object). At most one parameter is allowed to read from the message body.

This should work:

public HttpResponseMessage Post([FromBody] string name) { ... }

This will not work:

// Caution: This won't work!    
public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }

The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.

Wrap the Button in div with "text-center" class.

Just change this:

<!-- wrong -->
<div class="col-md-4 center-block">
    <button id="singlebutton" name="singlebutton" class="btn btn-primary center-block">Next Step!</button>
</div>

To this:

<!-- correct -->
<div class="col-md-4 text-center"> 
    <button id="singlebutton" name="singlebutton" class="btn btn-primary">Next Step!</button> 
</div>

Edit

As of BootstrapV4, center-block was dropped #19102 in favor of m-*-auto

I used this for a similar problem:

'catherine mc-nulty joséphina'.capitalize.gsub(/(\s+\w)/) { |stuff| stuff.upcase }

This handles the following weird cases I saw trying the previous answers:

• non-word characters like -
• accented characters common in names like é
• capital characters in the middle of the string

        for i in 1..<answer.count {

            let previousAttributes = answer[i - 1]

            let maximumSpacing: CGFloat = 8
            let origin = previousAttributes.frame.maxX

            if (origin + maximumSpacing + currentAttributes.frame.size.width < self.collectionViewContentSize.width && currentAttributes.frame.origin.x > previousAttributes.frame.origin.x) {

                frame.origin.x = origin + maximumSpacing
                currentAttributes.frame = frame
            }
        }

You can find the codes in the DB2 Information Center. Here's a definition of the -302 from the z/OS Information Center:

THE VALUE OF INPUT VARIABLE OR PARAMETER NUMBER position-number IS INVALID OR TOO LARGE FOR THE TARGET COLUMN OR THE TARGET VALUE

On Linux/Unix/Windows DB2, you'll look under SQL Messages to find your error message. If the code is positive, you'll look for SQLxxxxW, if it's negative, you'll look for SQLxxxxN, where xxxx is the code you're looking up.

One of the alternatives to Python's conditional expression

"yes" if boolean else "no"

is the following:

{True:"yes", False:"no"}[boolean]

which has the following nice extension:

{True:"yes", False:"no", None:"maybe"}[boolean_or_none]

The shortest alternative remains:

("no", "yes")[boolean]

but there is no alternative to

yes() if boolean else no()

if you want to avoid the evaluation of yes() and no(), because in

(no(), yes())[boolean]  # bad

both no() and yes() are evaluated.

Quote (read [here][1])-

When you use CAST to convert a CLOB value into a character datatype or a BLOB value into the RAW datatype, the database implicitly converts the LOB value to character or raw data and then explicitly casts the resulting value into the target datatype.

So, something like this should work-

report := CAST(report_clob AS VARCHAR2(100));

Or better yet use it as CAST(report_clob AS VARCHAR2(100)) where ever you are trying to use the BLOB as VARCHAR [1]: http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions016.htm

You can use this line to print the contents of your desktop:

FOR %%I in (C:\windows\desktop\*.*) DO echo %%I 

Once you have the %%I variable it's easy to perform a command on it (just replace the word echo with your program)

In addition, substitution of FOR variable references has been enhanced You can now use the following optional syntax:

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only (directory with \)
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

https://ss64.com/nt/syntax-args.html

In the above examples %I and PATH can be replaced by other valid values. The %~ syntax is terminated by a valid FOR variable name. Picking upper case variable names like %I makes it more readable and avoids confusion with the modifiers, which are not case sensitive.

You can get the full documentation by typing FOR /?

I had similar expirience like yours. I have Denwer server. When I loaded my http://new.new local site without using via script src jquery.min.js file at index.php in Chrome I got error 500 jquery.min.map in console. I resolved this problem simply - I disabled extension Wunderlist in Chrome and voila - I never see this error more. Although, No, I found this error again - when Wunderlist have been on again. So, check your extensions and try to disable all of them or some of them or one by one. Good luck!

You could use String.prototype.indexOf to accomplish that. Try something like this:

$('.type').keyup(function() {_x000D_
  var v = $(this).val();_x000D_
  if (v.indexOf('> <') !== -1) {_x000D_
    console.log('contains > <');_x000D_
  }_x000D_
  console.log(v);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<textarea class="type"></textarea>

Update

Modern browsers also have a String.prototype.includes method.

Here are the three web pages on which we found the answer. The most difficult part was setting up static ports for SQLEXPRESS.

Provisioning a SQL Server Virtual Machine on Windows Azure. These initial instructions provided 25% of the answer.

How to Troubleshoot Connecting to the SQL Server Database Engine. Reading this carefully provided another 50% of the answer.

How to configure SQL server to listen on different ports on different IP addresses?. This enabled setting up static ports for named instances (eg SQLEXPRESS.) It took us the final 25% of the way to the answer.

You could use sed:

ls * | sed -e 'p;s@_.*_@_@g' | xargs -n2 mv

result:

prefix_567.png prefix_efg.png

*to do a dry-run first, replace mv at the end with echo

Explanation:

• e: optional for only 1 sed command.
• p: to print the input to sed, in this case it will be the original file name before any renaming
• @: is a replacement of / character to make sed more readable. That is, instead of using sed s/search/replace/g, use s@search@replace@g
• _.* : the underscore is an escape character to refer to the actual '.' character zero or more times (as opposed to ANY character in regex)
• -n2: indicates that there are 2 outputs that need to be passed on to mv as parameters. for each input from ls, this sed command will generate 2 output, which will then supplied to mv.

Compilers translate

for (a; b; c)
{
    ...
}

to

a;
while(b)
{
    ...
 end:
    c;
}

So in your case (post/pre- increment) it doesn't matter.

EDIT: continues are simply replaced by goto end;

You can only use

     Object& return_Object();

if the object returned has a greater scope than the function. For example, you can use it if you have a class where it is encapsulated. If you create an object in your function, use pointers. If you want to modify an existing object, pass it as an argument.

  class  MyClass{
      private:
        Object myObj;

      public:
         Object& return_Object() {
            return myObj;
         }

         Object* return_created_Object() {
            return new Object();
         }

         bool modify_Object( Object& obj) {
            //  obj = myObj; return true; both possible
            return obj.modifySomething() == true;
         }
   };

OP didn't specify if the object is a nodeList, if it is then you can just use length method on it directly. Example:

buttons = document.querySelectorAll('[id=button)) {
console.log('Found ' + buttons.length + ' on the screen'); 

With jQuery its just: $(this).blur();

Implementing interfaces with abstract base classes is much simpler in modern Python 3 and they serve a purpose as an interface contract for plug-in extensions.

Create the interface/abstract base class:

from abc import ABC, abstractmethod

class AccountingSystem(ABC):

    @abstractmethod
    def create_purchase_invoice(self, purchase):
        pass

    @abstractmethod
    def create_sale_invoice(self, sale):
        log.debug('Creating sale invoice', sale)

Create a normal subclass and override all abstract methods:

class GizmoAccountingSystem(AccountingSystem):

    def create_purchase_invoice(self, purchase):
        submit_to_gizmo_purchase_service(purchase)

    def create_sale_invoice(self, sale):
        super().create_sale_invoice(sale)
        submit_to_gizmo_sale_service(sale)

You can optionally have common implementation in the abstract methods as in create_sale_invoice(), calling it with super() explicitly in the subclass as above.

Instantiation of a subclass that does not implement all the abstract methods fails:

class IncompleteAccountingSystem(AccountingSystem):
    pass

>>> accounting = IncompleteAccountingSystem()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Can't instantiate abstract class IncompleteAccountingSystem with abstract methods
create_purchase_invoice, create_sale_invoice

You can also have abstract properties, static and class methods by combining corresponding annotations with @abstractmethod.

Abstract base classes are great for implementing plugin-based systems. All imported subclasses of a class are accessible via __subclasses__(), so if you load all classes from a plugin directory with importlib.import_module() and if they subclass the base class, you have direct access to them via __subclasses__() and you can be sure that the interface contract is enforced for all of them during instantiation.

Here's the plugin loading implementation for the AccountingSystem example above:

...
from importlib import import_module

class AccountingSystem(ABC):

    ...
    _instance = None

    @classmethod
    def instance(cls):
        if not cls._instance:
            module_name = settings.ACCOUNTING_SYSTEM_MODULE_NAME
            import_module(module_name)
            subclasses = cls.__subclasses__()
            if len(subclasses) > 1:
                raise InvalidAccountingSystemError('More than one '
                        f'accounting module: {subclasses}')
            if not subclasses or module_name not in str(subclasses[0]):
                raise InvalidAccountingSystemError('Accounting module '
                        f'{module_name} does not exist or does not '
                        'subclass AccountingSystem')
            cls._instance = subclasses[0]()
        return cls._instance

Then you can access the accounting system plugin object through the AccountingSystem class:

>>> accountingsystem = AccountingSystem.instance()

(Inspired by this PyMOTW-3 post.)

As the documentation clearly states, Character.getNumericValue() returns the character's value as a digit.
It returns -1 if the character is not a digit.

If you want to get the numeric Unicode code point of a boxed Character object, you'll need to unbox it first:

int value = (int)c.charValue();

Subclipse for Eclipse has an excellent graphical diff plugin if you are using SVN (subversion) source control.

Best option would be

Add a compare validator to the web form. Set its controlToValidate. Set its Type property to Date. Set its operator property to DataTypeCheck eg:

<asp:CompareValidator
    id="dateValidator" runat="server" 
    Type="Date"
    Operator="DataTypeCheck"
    ControlToValidate="txtDatecompleted" 
    ErrorMessage="Please enter a valid date.">
</asp:CompareValidator>

Depending on the version, do:

version <2.3.0

Kill a hadoop job:

hadoop job -kill $jobId

You can get a list of all jobId's doing:

hadoop job -list

version >=2.3.0

Kill a hadoop job:

yarn application -kill $ApplicationId

You can get a list of all ApplicationId's doing:

yarn application -list

Just added to mrjandro's solution a quick hack to get rid of simple connection errors / timeouts.

You can adjust the threshold changing max_error_count variable value and add notifications of any sort.

import socket

max_error_count = 10

def increase_error_count():
    # Quick hack to handle false Port not open errors 
    with open('ErrorCount.log') as f:
        for line in f:
            error_count = line
    error_count = int(error_count)
    print "Error counter: " + str(error_count)
    file = open('ErrorCount.log', 'w')
    file.write(str(error_count + 1))
    file.close()
    if error_count == max_error_count:
        # Send email, pushover, slack or do any other fancy stuff
        print "Sending out notification"
        # Reset error counter so it won't flood you with notifications
        file = open('ErrorCount.log', 'w')
        file.write('0')
        file.close()

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(2) 
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
        print "Port is open"
else:
        print "Port is not open"
        increase_error_count()

And here you find a Python 3 compatible version (just fixed print syntax):

import socket

max_error_count = 10

def increase_error_count():
    # Quick hack to handle false Port not open errors
    with open('ErrorCount.log') as f:
        for line in f:
            error_count = line
    error_count = int(error_count)
    print ("Error counter: " + str(error_count))
    file = open('ErrorCount.log', 'w')
    file.write(str(error_count + 1))
    file.close()
    if error_count == max_error_count:
        # Send email, pushover, slack or do any other fancy stuff
        print ("Sending out notification")
        # Reset error counter so it won't flood you with notifications
        file = open('ErrorCount.log', 'w')
        file.write('0')
        file.close()

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(2) 
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
        print ("Port is open")
else:
        print ("Port is not open")
        increase_error_count()

I think you are looking for instance_of?. is_a? and kind_of? will return true for instances from derived classes.

class X < String
end

foo = X.new

foo.is_a? String         # true
foo.kind_of? String      # true
foo.instance_of? String  # false
foo.instance_of? X       # true

Don't worry... Its much easy to solve your problem. Just SET you SDK-LOCATION and JDK-LOCATION.

• Click on Configure ( As Soon Android studio open )
• Click Project Default
• Click Project Structure

• Clik Android Sdk Location

• Select & Browse your Android SDK Location (Like: C:\Android\sdk)

• Uncheck USE EMBEDDED JDK LOCATION

• Set & Browse JDK Location, Like C:\Program Files\Java\jdk1.8.0_121

Have you tried following the advice on the linked help page? The help page at http://g.co/mapsJSApiErrors says:

ApiNotActivatedMapError

The Google Maps JavaScript API is not activated on your API project. You may need to enable the Google Maps JavaScript API under APIs in the Google Developers Console.

See Obtaining an API key.

So check that the key you are using has Google Maps JavaScript API enabled.

Add a notifier in the viewWillAppear function

-(void)viewWillAppear:(BOOL)animated{
  [super viewWillAppear:animated];
  [[NSNotificationCenter defaultCenter] addObserver:self  selector:@selector(orientationChanged:)    name:UIDeviceOrientationDidChangeNotification  object:nil];
}

The orientation change notifies this function

- (void)orientationChanged:(NSNotification *)notification{
   [self adjustViewsForOrientation:[[UIApplication sharedApplication] statusBarOrientation]];
}

which in-turn calls this function where the moviePlayerController frame is orientation is handled

- (void) adjustViewsForOrientation:(UIInterfaceOrientation) orientation {

    switch (orientation)
    {
        case UIInterfaceOrientationPortrait:
        case UIInterfaceOrientationPortraitUpsideDown:
        { 
        //load the portrait view    
        }

            break;
        case UIInterfaceOrientationLandscapeLeft:
        case UIInterfaceOrientationLandscapeRight:
        {
        //load the landscape view 
        }
            break;
        case UIInterfaceOrientationUnknown:break;
    }
}

in viewDidDisappear remove the notification

-(void)viewDidDisappear:(BOOL)animated{
   [super viewDidDisappear:animated];
   [[NSNotificationCenter defaultCenter]removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];
}

I guess this is the fastest u can have changed the view as per orientation

The simple way to open the link in a new tab is to add a target attribute in the link having a value equals to "_blanl", like this :

<a href="http://www.WEBSITE_NAME.com" target="_blank"></a>

In java syntax:

rdd.collect().forEach(line -> System.out.println(line));

That library seems to allow validation for single elements. Just associate a click event to your button and try the following:

$("#myform").validate().element("#i1");

Examples here:

https://jqueryvalidation.org/Validator.element

This should work

 <a href="#" onclick="function hi(){alert('Hi!')};hi()">click</a>

You may inline any javascript inside the onclick as if you were assigning the method through javascript. I think is just a matter of making code cleaner keeping your js inside a script block

Recursion may well be faster where the alternative is to explicitly manage a stack, like in the sorting or binary tree algorithms you mention.

I've had a case where rewriting a recursive algorithm in Java made it slower.

So the right approach is to first write it in the most natural way, only optimize if profiling shows it is critical, and then measure the supposed improvement.

C is not object oriented programming (OOP) language. So you can not use properties in OOP. Eg. There is no .length property in C. So you need to use loops for your task.

EXEC sp_helplogins

You can also pass an "@LoginNamePattern" parameter to get information about a specific login:

EXEC sp_helplogins @LoginNamePattern='fred'

Preferences -> General -> Load preferences from a custom folder or URL

First time you choose this, it will automatically save a preferences file into this folder called "com.googlecode.iterm2.plist"

That's because the byte[] output is well, and array of bytes, you may think on it as an array of bytes representing each one an integer, but when you add them all into a single string you get something that is NOT an integer, that's why. You may either have it as an array of integers or try to create an instance of BigInteger.

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

I believe, the 500ms run in the background, while the rest of the code continues to execute and empties the list.

Then after 500ms nothing happens, as no function-call is implemented in the after-callup (same as frame.after(500, function=None))

The reason it is not working is because javascript strings must be terminated before the next newline character (not a \n obviously). The reason \n exists is to allow developers an easy way to put the newline character (ASCII: 10) into their strings.

When you have a string which looks like this:

//Note lack of terminating double quote
var foo = "Bob 

Your code will have a syntax error at that point and cease to run.

If you wish to have a string which spans multiple lines, you may insert a backslash character '\' just before you terminate the line, like so:

//Perfectly valid code
var foo = "Bob \
is \
cool.";

However that string will not contain \n characters in the positions where the string was broken into separate lines. The only way to insert a newline into a string is to insert a character with a value of 10, the easiest way of which is the \n escape character.

var foo = "Bob\nis\ncool.";

class BooleanTester
{
    boolean primitive;
    Boolean object;

    public static void main(String[] args) {
        BooleanTester booleanTester = new BooleanTester();
        System.out.println("primitive: " + booleanTester.getPrimitive());
        System.out.println("object: " + booleanTester.getObject());
}

    public boolean getPrimitive() {
        return primitive;
    }

    public Boolean getObject() {
        return object;
    }
}

output:

primitive: false
object: null

This seems obvious but I had a situation where Jackson, while serializing an object to JSON, was throwing an NPE after calling a getter, just like this one, that returns a primitive boolean which was not assigned. This led me to believe that Jackson was receiving a null and trying to call a method on it, hence the NPE. I was wrong.

Moral of the story is that when Java allocates memory for a primitive, that memory has a value even if not initialized, which Java equates to false for a boolean. By contrast, when allocating memory for an uninitialized complex object like a Boolean, it allocates only space for a reference to that object, not the object itself - there is no object in memory to refer to - so resolving that reference results in null.

I think that strictly speaking, "defaults to false" is a little off the mark. I think Java does not allocate the memory and assign it a value of false until it is explicitly set; I think Java allocates the memory and whatever value that memory happens to have is the same as the value of 'false'. But for practical purpose they are the same thing.

Following will give you active connections/ queries in postgres DB-

SELECT 
    pid
    ,datname

FROM pg_stat_activity
WHERE state = 'active';

You may use 'idle' instead of active to get already executed connections/queries.
