I found that when within a Miniconda3 environment I had to run:

conda deactivate

Neither deactivate nor source deactivate worked for me.

Just to echo what @skytreader had previously commented, rmvirtualenv is a command provided by virtualenvwrapper, not virtualenv. Maybe you didn't have virtualenvwrapper installed?

See VirtualEnvWrapper Command Reference for more details.

If you came here from Google, trying to find where your previously created virtualenv installation ended up, and why there is no command to find it, here's the low-down.

The design of virtualenv has a fundamental flaw of not being able to keep track of it's own created environments. Someone was not quite in their right mind when they created virtualenv without having a rudimentary way to keep track of already created environments, and certainly not fit for a time and age when most pip requirements require multi-giga-byte installations, which should certainly not go into some obscure .virtualenvs sub-directory of your ~/home.

IMO, the created virtualenv directory should be created in $CWD and a file called ~/.virtualenv (in home) should keep track of the name and path of that creation. Which is a darn good reason to use Conda/Miniconda3 instead, which does seem to keep good track of this.

As answered here, the only way to keep track of this, is to install yet another package called virtualenvwrapper. If you don't do that, you will have to search for the created directory by yourself. Clearly, if you don't remember the name or the location it was created with/at, you will most likely never find your virtual environment again...

One try to remedy the situation in windows, is by putting the following functions into your powershell profile:

# wrap virtualenv.exe and write last argument (presumably 
# your virtualenv name) to the file: $HOME/.virtualenv.
function ven { if( $args.count -eq 0) {Get-Content ~/.virtualenv } else {virtualenv.exe "$args"; Write-Output ("{0} `t{1}" -f $args[-1],$PWD) | Out-File -Append $HOME/.virtualenv }}

# List what's in the file or the directories under ~/.virtualenvs
function lsven { try {Get-Content ~/.virtualenv } catch {Get-ChildItem ~\.virtualenvs -Directory | Select-Object -Property Name } }

_{WARNING: This will write to ~\.virtualenv...}

Since I just went though a drag, I'll try to write the answer I'd have wished for two hours ago. This is for people who don't just want the copy&paste solution

First: Do you wonder why copying and pasting paths works for some people while it doesn't work for others?** The main reason, solutions differ are different python versions, 2.x or 3.x. There are actually distinct versions of virtualenv and virtualenvwrapper that work with either python 2 or 3. If you are on python 2 install like so:

sudo pip install virutalenv
sudo pip install virtualenvwrapper

If you are planning to use python 3 install the related python 3 versions

sudo pip3 install virtualenv
sudo pip3 install virtualenvwrapper

You've successfully installed the packages for your python version and are all set, right? Well, try it. Type workon into your terminal. Your terminal will not be able to find the command (workon is a command of virtualenvwrapper). Of course it won't. Workon is an executable that will only be available to you once you load/source the file virtualenvwrapper.sh. But the official installation guide has you covered on this one, right?. Just open your .bash_profile and insert the following, it says in the documentation:

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh

Especially the command source /usr/local/bin/virtualenvwrapper.sh seems helpful since the command seems to load/source the desired file virtualenvwrapper.sh that contains all the commands you want to work with like workon and mkvirtualenv. But yeah, no. When following the official installation guide, you are very likely to receive the error from the initial post: mkvirtualenv: command not found. Still no command is being found and you are still frustrated. So whats the problem here? The problem is that virtualenvwrapper.sh is not were you are looking for it right now. Short reminder ... you are looking here:

source /usr/local/bin/virtualenvwrapper.sh

But there is a pretty straight forward way to finding the desired file. Just type

which virtualenvwrapper

to your terminal. This will search your PATH for the file, since it is very likely to be in some folder that is included in the PATH of your system.

If your system is very exotic, the desired file will hide outside of a PATH folder. In that case you can find the path to virtalenvwrapper.sh with the shell command find / -name virtualenvwrapper.sh

Your result may look something like this: /Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh Congratulations. You have found your missing file!. Now all you have to do is changing one command in your .bash_profile. Just change:

source "/usr/local/bin/virtualenvwrapper.sh"

to:

"/Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh"

Congratulations. Virtualenvwrapper does now work on your system. But you can do one more thing to enhance your solution. If you've found the file virtualenvwrapper.sh with the command which virtualenvwrapper.sh you know that it is inside of a folder of the PATH. So if you just write the filename, your file system will assume the file is inside of a PATH folder. So you you don't have to write out the full path. Just type:

source "virtualenvwrapper.sh"

Thats it. You are no longer frustrated. You have solved your problem. Hopefully.

If you are using python3, then try this(My OS is Ubuntu 16.04):

sudo apt-get install python3-mysqldb

It worked for me on windows with python 2 installation :

1. Step 1: Install python 3 version .
2. Step 2: create a env folder for the virtual environment.
3. Step 3 : c:\Python37\python -m venv c:\path\to\env.

This is how i created Python 3 virtual environment on my existing python 2 installation.

Have you installed it using sudo? Was the error in my case.

Let's start with the problems these tools want to solve:

My system package manager don't have the Python versions I wanted or I want to install multiple Python versions side by side, Python 3.9.0 and Python 3.9.1, Python 3.5.3, etc

Then use pyenv.

I want to install and run multiple applications with different, conflicting dependencies.

Then use virtualenv or venv. These are almost completely interchangeable, the difference being that virtualenv supports older python versions and has a few more minor unique features, while venv is in the standard library.

I'm developing an /application/ and need to manage my dependencies, and manage the dependency resolution of the dependencies of my project.

Then use pipenv or poetry.

I'm developing a /library/ or a /package/ and want to specify the dependencies that my library users need to install

Then use setuptools.

I used virtualenv, but I don't like virtualenv folders being scattered around various project folders. I want a centralised management of the environments and some simple project management

Then use virtualenvwrapper. Variant: pyenv-virtualenvwrapper if you also use pyenv.

Not recommended

• pyvenv. This is deprecated, use venv or virtualenv instead. Not to be confused with pipenv or pyenv.

On Ubuntu; using mkvirtualenv -p python3 env_name loads the virtualenv with python3.

Inside the env, use python --version to verify.

In Java you can use GET which shows requested data on URL.But POST method cannot , because POST has body but GET donot have body.

I had a similar issue to solve in an app and I used the following method. I didn't use notifications for handling the navigation.

I have three storyboards in the app.

1. Splash screen storyboard - for app initialisation and checking if the user is already logged in
2. Login storyboard - for handling user login flow
3. Tab bar storyboard - for displaying the app content

My initial storyboard in the app is Splash screen storyboard. I have navigation controller as the root of login and tab bar storyboard to handle view controller navigations.

I created a Navigator class to handle the app navigation and it looks like this:

class Navigator: NSObject {

   static func moveTo(_ destinationViewController: UIViewController, from sourceViewController: UIViewController, transitionStyle: UIModalTransitionStyle? = .crossDissolve, completion: (() -> ())? = nil) {
       

       DispatchQueue.main.async {

           if var topController = UIApplication.shared.keyWindow?.rootViewController {

               while let presentedViewController = topController.presentedViewController {

                   topController = presentedViewController

               }

               
               destinationViewController.modalTransitionStyle = (transitionStyle ?? nil)!

               sourceViewController.present(destinationViewController, animated: true, completion: completion)

           }

       }

   }

}

Let's look at the possible scenarios:

• First app launch; Splash screen will be loaded where I check if the user is already signed in. Then login screen will be loaded using the Navigator class as follows;

Since I have navigation controller as the root, I instantiate the navigation controller as initial view controller.

let loginSB = UIStoryboard(name: "splash", bundle: nil)

let loginNav = loginSB.instantiateInitialViewcontroller() as! UINavigationController

Navigator.moveTo(loginNav, from: self)

This removes the slpash storyboard from app window's root and replaces it with login storyboard.

From login storyboard, when the user is successfully logged in, I save the user data to User Defaults and initialize a UserData singleton to access the user details. Then Tab bar storyboard is loaded using the navigator method.

Let tabBarSB = UIStoryboard(name: "tabBar", bundle: nil)
let tabBarNav = tabBarSB.instantiateInitialViewcontroller() as! UINavigationController

Navigator.moveTo(tabBarNav, from: self)

Now the user signs out from the settings screen in tab bar. I clear all the saved user data and navigate to login screen.

let loginSB = UIStoryboard(name: "splash", bundle: nil)

let loginNav = loginSB.instantiateInitialViewcontroller() as! UINavigationController

Navigator.moveTo(loginNav, from: self)

• User is logged in and force kills the app

When user launches the app, Splash screen will be loaded. I check if user is logged in and access the user data from User Defaults. Then initialize the UserData singleton and shows tab bar instead of login screen.

import matplotlib.pyplot as plt
plt.savefig("image.png")

In Jupyter Notebook you have to remove plt.show() and add plt.savefig(), together with the rest of the plt-code in one cell. The image will still show up in your notebook.

use this function to get a standard array back of the type you are after...

return get_object_vars($booking);

I also struggled with this same issue. But I was able to manage this problem by using following code segment. Use this in your blade template.

<input type="hidden" value="{{$old_section = "whatever" }}">

{{$old_section }}

For files in current working directory without specifying a path

Python 2.7:

import os
os.listdir('.')

Python 3.x:

import os
os.listdir()

After login I had the same problem so I used

@Override
protected void onRestart() {
    this.recreate();
    super.onRestart();
}

The simplest (Non Win32) way is to add a UserForm to your VBA project (if you don't already have one) or alternatively add a reference to Microsoft Forms 2 Object Library, then from a sheet/module you can simply:

With New MSForms.DataObject
    .SetText "http://zombo.com"
    .PutInClipboard
End With

to set session you can try this:

$request->session()->put('key','value');

also to get session data you can try this:

$request->session()->get('key');

If you want to get all session data:

$request->session()->all();

Very late answer, but I think my answer is more straight forward for specific use cases where users want to simply insert (copy) data from table A into table B:

INSERT INTO table_b (col1, col2, col3, col4, col5, col6)
SELECT col1, 'str_val', int_val, col4, col5, col6
FROM table_a

Yes include the first file into the second. That's all.

See an example below,

File1.php :

<?php
  function first($int, $string){ //function parameters, two variables.
    return $string;  //returns the second argument passed into the function
  }
?>

Now Using include (http://php.net/include) to include the File1.php to make its content available for use in the second file:

File2.php :

<?php
  include 'File1.php';
  echo first(1,"omg lol"); //returns omg lol;
?>

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

Remember that by default the return value from the input will be a string and not an integer. You cannot compare strings with booleans like <, >, =>, <= (unless you are comparing the length). Therefore your code should look like this:

number = 23
guess = int(input('Enter a number: '))  # The var guess will be an integer

if guess == number:
    print('Congratulations! You guessed it.')

elif guess != number:
    print('Wrong Number')

Plain Java 8 solutions using a Stream.

Constant number

Assuming private Collection<T> c, c2, c3.

One solution:

public Stream<T> stream() {
    return Stream.concat(Stream.concat(c.stream(), c2.stream()), c3.stream());
}

Another solution:

public Stream<T> stream() {
    return Stream.of(c, c2, c3).flatMap(Collection::stream);
}

Variable number

Assuming private Collection<Collection<T>> cs:

public Stream<T> stream() {
    return cs.stream().flatMap(Collection::stream);
}

What you can do to resolve your conflict is

svn resolve --accept working -R <path>

where <path> is where you have your conflict (can be the root of your repo).

Explanations:

• resolve asks svn to resolve the conflict
• accept working specifies to keep your working files
• -R stands for recursive

Hope this helps.

EDIT:

To sum up what was said in the comments below:

• <path> should be the directory in conflict (C:\DevBranch\ in the case of the OP)
• it's likely that the origin of the conflict is
  • either the use of the svn switch command
  • or having checked the Switch working copy to new branch/tag option at branch creation
• more information about conflicts can be found in the dedicated section of Tortoise's documentation.
• to be able to run the command, you should have the CLI tools installed together with Tortoise:

Quite simply as follows:

/**
 * @author The Elite Gentleman
 *
 */
public enum MyEnum {
    ONE("one"), TWO("two")
    ;
    private final String value;

    private MyEnum(final String value) {
        this.value = value;
    }

    public String getValue() {
        return value;
    }

    @Override
    public String toString() {
        // TODO Auto-generated method stub
        return getValue();
    }
}

Update, since you've updated your post, I've changed my value from an int to a String.

Android Market requires you to sign all apps you publish with a certificate, using a public/private key mechanism (the certificate is signed with your private key). This provides a layer of security that prevents, among other things, remote attackers from pushing malicious updates to your application to market (all updates must be signed with the same key).

From The App-Signing Guide of the Android Developer's site:

In general, the recommended strategy for all developers is to sign all of your applications with the same certificate, throughout the expected lifespan of your applications. There are several reasons why you should do so...

Using the same key has a few benefits - One is that it's easier to share data between applications signed with the same key. Another is that it allows multiple apps signed with the same key to run in the same process, so a developer can build more "modular" applications.

You can achieve this by using ArgumentCaptor

Imagine you have bean function like so.

public interface Application {
  public String myFunction(String abc);
}

Then in your test class:

//Use ArgumentCaptor to capture the value
ArgumentCaptor<String> param = ArgumentCaptor.forClass(String.class);


when(mock.myFunction(param.capture())).thenAnswer(new Answer<String>() {
    @Override
    public String answer(InvocationOnMock invocation) throws Throwable {
      return param.getValue();//return the captured value.
    }
  });

OR if you fan of lambda simply do:

//Use ArgumentCaptor to capture the value
ArgumentCaptor<String> param = ArgumentCaptor.forClass(String.class);


when(mock.myFunction(param.capture()))
    .thenAnswer((invocation) -> param.getValue());

Summary: Use argumentcaptor, to capture the parameter passed. Later in answer return the value captured using getValue.

There are many ways. You use RelativeLayout or AbsoluteLayout.

With relative, you can have the image align with parent on the left side for example and also have the text align to the parent left too... then you can use margins and padding and gravity on the text view to get it lined where you want over the image.

You install a new version of R from the official website.

RStudio should automatically start with the new version when you relaunch it.

In case you need to do it manually, in RStudio, go to :Tools -> options -> General.

Check @micstr's answer for a more detailed walkthrough.

In regard to the "You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array, or Iterable" error.

This could happen if you import { Observable } from 'rxjs' after (below) some module/function/whatever, which actually uses it.

Solution: move this import above the import of that module.

I would like to add Java Spring specific configuration that can effect on this.

In Web site or Gateway application there is a contentSecurityPolicy setting

in Spring you can find implementation of WebSecurityConfigurerAdapter sub class

contentSecurityPolicy("
script-src 'self' [URLDomain]/scripts ; 
style-src 'self' [URLDomain]/styles;
frame-src 'self' [URLDomain]/frameUrl...

...

.referrerPolicy(ReferrerPolicyHeaderWriter.ReferrerPolicy.STRICT_ORIGIN_WHEN_CROSS_ORIGIN)

Browser will be blocked if you have not define safe external contenet here.

How about:

Dir["/path/to/directory/*.rb"].each {|file| require file }

The only thing that worked in my case was by using david valentine code. Using Root Attr. in the Person class did not help.

I have this simple Xml:

<?xml version="1.0"?>
<personList>
 <Person>
  <FirstName>AAAA</FirstName>
  <LastName>BBB</LastName>
 </Person>
 <Person>
  <FirstName>CCC</FirstName>
  <LastName>DDD</LastName>
 </Person>
</personList>

C# class:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

De-Serialization C# code from a Main method:

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "personList";
xRoot.IsNullable = true;
using (StreamReader reader = new StreamReader(xmlFilePath))
{
List<Person> result = (List<Person>)(new XmlSerializer(typeof(List<Person>), xRoot)).Deserialize(reader);
 int numOfPersons = result.Count;
}  

This was a very important issue for me in order for my site to be multilingual. So here is my conclusion tested in Firefox and Chrome.

jQuery trigger comes in handy.

So this hides the standard boring type=file labels. You can place any label you want and format anyway. I customized a script from http://demo.smarttutorials.net/ajax1/. The script allows multiple file uploads with thumbnail preview and uses PHP and MySQL.

<form enctype="multipart/form-data" name='imageform' role="form"    ="imageform" method="post" action="upload_ajax.php">
    <div class="form-group">
        <div id="select_file">Select a file</div>
        <input class='file' type="file" style="display: none " class="form-control" name="images_up" id="images_up" placeholder="Please choose your image">
        <div id="my_file"></div>
        <span class="help-block"></span>
    </div>
    <div id="loader" style="display: none;">
        Please wait image uploading to server....
    </div>
    <input type="submit" value="Upload" name="image_upload" id="image_upload" class="btn"/>
</form>

$('#select_file').click(function() {
    $('#images_up').trigger('click');
    $('#images_up').change(function() {
        var filename = $('#images_up').val();
        if (filename.substring(3,11) == 'fakepath') {
            filename = filename.substring(12);
        } // Remove c:\fake at beginning from localhost chrome
        $('#my_file').html(filename);
   });
});

Here's is quite a list of jQuery plugins that will help achieve similar effect: http://jquery-plugins.net/tag/sticky-scroll

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

for (int i=0; i<dt_pattern.Rows.Count; i++)
{
    DataRow dr = dt_pattern.Rows[i];
}

In the loop, you can now reference row i+1 (assuming there is an i+1)

First, here's some sample data:

set.seed(1)
dat <- data.frame(one = rnorm(15),
                 two = sample(LETTERS, 15),
                 three = rnorm(15),
                 four = runif(15))
dat <- data.frame(lapply(dat, function(x) { x[sample(15, 5)] <- NA; x }))
head(dat)
#          one  two       three      four
# 1         NA    M  0.80418951 0.8921983
# 2  0.1836433    O -0.05710677        NA
# 3 -0.8356286    L  0.50360797 0.3899895
# 4         NA    E          NA        NA
# 5  0.3295078    S          NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595

Here's our replacement:

dat[["four"]][is.na(dat[["four"]])] <- 0
head(dat)
#          one  two       three      four
# 1         NA    M  0.80418951 0.8921983
# 2  0.1836433    O -0.05710677 0.0000000
# 3 -0.8356286    L  0.50360797 0.3899895
# 4         NA    E          NA 0.0000000
# 5  0.3295078    S          NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595

Alternatively, you can, of course, write dat$four[is.na(dat$four)] <- 0

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

See also PostgreSQL row storage fundamentals

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

Lazy and compact storing text in the Tag property

If you are a bit lazy and do not use the Tag property of the controls for anything else you can use it to store the tooltip text and assign MouseHover event handlers to all such controls in one go like this:

private System.Windows.Forms.ToolTip ToolTip1;
private void PrepareTooltips()
{
    ToolTip1 = new System.Windows.Forms.ToolTip();
    foreach(Control ctrl in this.Controls)
    {
        if (ctrl is Button && ctrl.Tag is string)
        {
            ctrl.MouseHover += new EventHandler(delegate(Object o, EventArgs a)
            {
                var btn = (Control)o;
                ToolTip1.SetToolTip(btn, btn.Tag.ToString());
            });
        }
    }
}

In this case all buttons having a string in the Tag property is assigned a MouseHover event. To keep it compact the MouseHover event is defined inline using a lambda expression. In the event any button hovered will have its Tag text assigned to the Tooltip and shown.

It depends on what you are trying to print. You need a third party pdf printer application or if you are printing data of your own you can use report viewer in visual studio. It can output reports to excel and pdf -files.

This is PHP script for checking.

$xsession = `pidof X`;
if (!$xsession) {
    echo "There is no active X session, aborting..\n";
    exit;
}

Similar command can be used in shell script too. like the pidof command.

You can use static class or Singleton pattern.

If you are looking for a way to "mount" files, like -v for docker run, you can now use the --secret flag for docker build

echo 'WARMACHINEROX' > mysecret.txt
docker build --secret id=mysecret,src=mysecret.txt .

And inside your Dockerfile you can now access this secret

# syntax = docker/dockerfile:1.0-experimental
FROM alpine

# shows secret from default secret location:
RUN --mount=type=secret,id=mysecret cat /run/secrets/mysecret

# shows secret from custom secret location:
RUN --mount=type=secret,id=mysecret,dst=/foobar cat /foobar

More in-depth information about --secret available on Docker Docs

Can you use date as a factor?

Yes, but you probably shouldn't.

...or should you use as.Date on a date column?

Yes.

Which leads us to this:

library(scales)
df$Month <- as.Date(df$Month)
ggplot(df, aes(x = Month, y = AvgVisits)) + 
  geom_bar(stat = "identity") +
  theme_bw() +
  labs(x = "Month", y = "Average Visits per User") +
  scale_x_date(labels = date_format("%m-%Y"))

in which I've added stat = "identity" to your geom_bar call.

In addition, the message about the binwidth wasn't an error. An error will actually say "Error" in it, and similarly a warning will always say "Warning" in it. Otherwise it's just a message.

It should be implemented as a free, non-friend functions, especially if, like most things these days, the output is mainly used for diagnostics and logging. Add const accessors for all the things that need to go into the output, and then have the outputter just call those and do formatting.

I've actually taken to collecting all of these ostream output free functions in an "ostreamhelpers" header and implementation file, it keeps that secondary functionality far away from the real purpose of the classes.

You should enable the management plugin.

rabbitmq-plugins enable rabbitmq_management

See here:

http://www.rabbitmq.com/plugins.html

And here for the specifics of management.

http://www.rabbitmq.com/management.html

Finally once set up you will need to follow the instructions below to install and use the rabbitmqadmin tool. Which can be used to fully interact with the system. http://www.rabbitmq.com/management-cli.html

For example:

rabbitmqadmin get queue=<QueueName> requeue=false

will give you the first message off the queue.

Guys thank you for your help. I think all of this answers works. However i think my byte array contains raw bytes. That's why all of those solutions didnt work for my code.

However i found a solution. Maybe this solution helps other coders who have problem like mine.

static byte[] PadLines(byte[] bytes, int rows, int columns) {
   int currentStride = columns; // 3
   int newStride = columns;  // 4
   byte[] newBytes = new byte[newStride * rows];
   for (int i = 0; i < rows; i++)
       Buffer.BlockCopy(bytes, currentStride * i, newBytes, newStride * i, currentStride);
   return newBytes;
 }

 int columns = imageWidth;
 int rows = imageHeight;
 int stride = columns;
 byte[] newbytes = PadLines(imageData, rows, columns);

 Bitmap im = new Bitmap(columns, rows, stride, 
          PixelFormat.Format8bppIndexed, 
          Marshal.UnsafeAddrOfPinnedArrayElement(newbytes, 0));

 im.Save("C:\\Users\\musa\\Documents\\Hobby\\image21.bmp");

This solutions works for 8bit 256 bpp (Format8bppIndexed). If your image has another format you should change PixelFormat .

And there is a problem with colors right now. As soon as i solved this one i will edit my answer for other users.

*PS = I am not sure about stride value but for 8bit it should be equal to columns.

And also this function Works for me.. This function copies 8 bit greyscale image into a 32bit layout.

public void SaveBitmap(string fileName, int width, int height, byte[] imageData)
        {

            byte[] data = new byte[width * height * 4];

            int o = 0;

            for (int i = 0; i < width * height; i++)
            {
                byte value = imageData[i];


                data[o++] = value;
                data[o++] = value;
                data[o++] = value;
                data[o++] = 0; 
            }

            unsafe
            {
                fixed (byte* ptr = data)
                {

                    using (Bitmap image = new Bitmap(width, height, width * 4,
                                PixelFormat.Format32bppRgb, new IntPtr(ptr)))
                    {

                        image.Save(Path.ChangeExtension(fileName, ".jpg"));
                    }
                }
            }
        }

 Toast toast=Toast.makeText(getApplicationContext(),"Hello", Toast.LENGTH_SHORT);
 toast.setGravity(Gravity.CENTER, 0, 0); // last two args are X and Y are used for setting position
 toast.setDuration(10000);//you can even use milliseconds to display toast
 toast.show();**//showing the toast is important**

I think the classic answer is to create a more decoupled application, which has no knowledge of which implementation will be used during runtime.

For example, we're a central payment provider, working with many payment providers around the world. However, when a request is made, I have no idea which payment processor I'm going to call. I could program one class with a ton of switch cases, such as:

class PaymentProcessor{

    private String type;

    public PaymentProcessor(String type){
        this.type = type;
    }

    public void authorize(){
        if (type.equals(Consts.PAYPAL)){
            // Do this;
        }
        else if(type.equals(Consts.OTHER_PROCESSOR)){
            // Do that;
        }
    }
}

Now imagine that now you'll need to maintain all this code in a single class because it's not decoupled properly, you can imagine that for every new processor you'll support, you'll need to create a new if // switch case for every method, this only gets more complicated, however, by using Dependency Injection (or Inversion of Control - as it's sometimes called, meaning that whoever controls the running of the program is known only at runtime, and not complication), you could achieve something very neat and maintainable.

class PaypalProcessor implements PaymentProcessor{

    public void authorize(){
        // Do PayPal authorization
    }
}

class OtherProcessor implements PaymentProcessor{

    public void authorize(){
        // Do other processor authorization
    }
}

class PaymentFactory{

    public static PaymentProcessor create(String type){

        switch(type){
            case Consts.PAYPAL;
                return new PaypalProcessor();

            case Consts.OTHER_PROCESSOR;
                return new OtherProcessor();
        }
    }
}

interface PaymentProcessor{
    void authorize();
}

** The code won't compile, I know :)

Just use

id(object)

How about?

function callHttpService(url, params){
  // Assume params contains key/value request params
  let queryStrings = '';

  for(let key in params){
      queryStrings += `${key}=${params[key]}&`
    } 
 const fullUrl = `${url}?queryStrings`

  //make http request with fullUrl
}

I was creating several buttons for each phone number in an array so each button needed a different phone number to call. I used the setTag function as I was creating several buttons within a for loop:

for (NSInteger i = 0; i < _phoneNumbers.count; i++) {

    UIButton *phoneButton = [[UIButton alloc] initWithFrame:someFrame];
    [phoneButton setTitle:_phoneNumbers[i] forState:UIControlStateNormal];

    [phoneButton setTag:i];

    [phoneButton addTarget:self
                    action:@selector(call:)
          forControlEvents:UIControlEventTouchUpInside];
}

Then in my call: method I used the same for loop and an if statement to pick the correct phone number:

- (void)call:(UIButton *)sender
{
    for (NSInteger i = 0; i < _phoneNumbers.count; i++) {
        if (sender.tag == i) {
            NSString *callString = [NSString stringWithFormat:@"telprompt://%@", _phoneNumbers[i]];
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callString]];
        }
    }
}

%u is used for unsigned integer. Since the memory address given by the signed integer address operator %d is -12, to get this value in unsigned integer, Compiler returns the unsigned integer value for this address.

It's just the wrong order

var e = $('<div style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
$('#box').append(e);    
e.attr('id', 'myid');

Append first and then access/set attr.

This should do the trick:

SET FOREIGN_KEY_CHECKS=0; DROP TABLE bericht; SET FOREIGN_KEY_CHECKS=1;

As others point out, this is almost never what you want, even though it's whats asked in the question. A more safe solution is to delete the tables depending on bericht before deleting bericht. See CloudyMarble answer on how to do that. I use bash and the method in my post to drop all tables in a database when I don't want to or can't delete and recreate the database itself.

The #1217 error happens when other tables has foreign key constraints to the table you are trying to delete and you are using the InnoDB database engine. This solution temporarily disables checking the restraints and then re-enables them. Read the documentation for more. Be sure to delete foreign key restraints and fields in tables depending on bericht, otherwise you might leave your database in a broken state.

Michael Richardson's solution is great. If you would like to subtract dates (because Google will point you here if you search for it), you could also say:

var date1 = moment( "2014-06-07 00:03:00" );
var date2 = moment( "2014-06-07 09:22:00" );

differenceInMs = date2.diff(date1); // diff yields milliseconds
duration = moment.duration(differenceInMs); // moment.duration accepts ms
differenceInMinutes = duration.asMinutes(); // if you would like to have the output 559

Give your two buttons the same name and different values:

<input type="submit" name="submit_button" value="Do Something">
<input type="submit" name="submit_button" value="Do Something Else">

Then in your Flask view function you can tell which button was used to submit the form:

def contact():
    if request.method == 'POST':
        if request.form['submit_button'] == 'Do Something':
            pass # do something
        elif request.form['submit_button'] == 'Do Something Else':
            pass # do something else
        else:
            pass # unknown
    elif request.method == 'GET':
        return render_template('contact.html', form=form)

Yes.

Yes it is.

Vanilla JS is always more efficient.

Lets say above one is your original dataframe and you want to add a new column 'old'

If age greater than 50 then we consider as older=yes otherwise False

step 1: Get the indexes of rows whose age greater than 50

row_indexes=df[df['age']>=50].index

step 2: Using .loc we can assign a new value to column

df.loc[row_indexes,'elderly']="yes"

same for age below less than 50

row_indexes=df[df['age']<50].index

df[row_indexes,'elderly']="no"

If you want to use straight PowerShell check out the below code.

$content = Get-Content C:\Users\You\Documents\test.txt
foreach ($line in $content)
{
    Write-Host $line
}

httpbin.org uses this method:

return jsonify(origin=request.headers.get('X-Forwarded-For', request.remote_addr))

As soon as question is about dynamic array you may want not just to create array with variable size, but also to change it's size during runtime. Here is an example with memcpy, you can use memcpy_s or std::copy as well. Depending on compiler, <memory.h> or <string.h> may be required. When using this functions you allocate new memory region, copy values of original memory regions to it and then release them.

//    create desired array dynamically
size_t length;
length = 100; //for example
int *array = new int[length];

//   now let's change is's size - e.g. add 50 new elements
size_t added = 50;
int *added_array = new int[added];

/*   
somehow set values to given arrays
*/ 

//    add elements to array
int* temp = new int[length + added];
memcpy(temp, array, length * sizeof(int));
memcpy(temp + length, added_array, added * sizeof(int));
delete[] array;
array = temp;

You may use constant 4 instead of sizeof(int).

As of IE11, you need to use addEventListener. attachEvent is deprecated and throws an error.

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

I don't think that it is possible. but you can do UITableView(grouped) with 1 section and 1 empty cell and use it as a container for your UITextView.

Active mode: -server initiates the connection.

Passive mode: -client initiates the connection.

Try these commands to remove all users' usernames and emails.

git config --global --unset-all user.name
git config --global --unset-all user.email

I didn't know the existing sa password so this is what I did:

1. Open Services in Control Panel

2. Find the "SQL Server (SQLEXPRESS)" entry and select properties

3. Stop the service

4. Enter "-m" at the beginning of the "Start parameters" fields. If there are other parameters there already add a semi-colon after -m;

5. Start the service

6. Open a Command Prompt

Enter the command:

osql -S YourPcName\SQLEXPRESS -E

(change YourPcName to whatever your PC is called).

7. At the prompt type the following commands:

alter login sa enable
go
sp_password NULL,'new_password','sa'
go
quit

8. Stop the "SQL Server (SQLEXPRESS)" service

9. Remove the "-m" from the Start parameters field

10. Start the service

On linux, you cannot/shouldnot get "Total Available Physical Memory" with SysInfo's freeram or by doing some arithmetic on totalram. The recommended way to do this is by reading proc/meminfo, quoting https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=34e431b0ae398fc54ea69ff85ec700722c9da773:

Many load balancing and workload placing programs check /proc/meminfo to estimate how much free memory is available. They generally do this by adding up "free" and "cached", which was fine ten years ago, but is pretty much guaranteed to be wrong today.

It is more convenient to provide such an estimate in /proc/meminfo. If things change in the future, we only have to change it in one place.

One way to do it is as https://stackoverflow.com/a/350039/7984460 suggest: read the file, and use fscanf to grab the line (but instead of going for MemTotal, go for MemAvailable)

Likewise, if you want to get the total amounf of physical memory used, depending on what you mean by "use", you might not want to subtract freeram from totalram, but subtract memavailable from memtotal to get what top/htop tell you.

scandir:

$files = scandir('folder/');
foreach($files as $file) {
  //do your work here
}

or glob may be even better for your needs:

$files = glob('folder/*.{jpg,png,gif}', GLOB_BRACE);
foreach($files as $file) {
  //do your work here
}

Just browse up to your installation's directory and execute this file "pg_env.bat", so after go at bin folder and execute pgAdmin.exe. This must work no doubt!

Don't return Strings in your methods but Customer objects it self and let JAXB take care of the de/serialization.

With the solutions already discussed above the most reliable one is using Browsermob-Proxy

But while working with the remote grid machine, Browsermob-proxy isn't really helpful.

This is how I fixed the problem in my case. Hopefully, might be helpful for anyone with a similar setup.

1. Add the ModHeader extension to the chrome browser

How to download the Modheader? Link

ChromeOptions options = new ChromeOptions();
options.addExtensions(new File(C://Downloads//modheader//modheader.crx));

// Set the Desired capabilities 
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);

// Instantiate the chrome driver with capabilities
WebDriver driver = new RemoteWebDriver(new URL(YOUR_HUB_URL), options);

2. Go to the browser extensions and capture the Local Storage context ID of the ModHeader

3. Navigate to the URL of the ModHeader to set the Local Storage Context

.

// set the context on the extension so the localStorage can be accessed
driver.get("chrome-extension://idgpnmonknjnojddfkpgkljpfnnfcklj/_generated_background_page.html");

Where `idgpnmonknjnojddfkpgkljpfnnfcklj` is the value captured from the Step# 2

4. Now add the headers to the request using Javascript

.

   ((Javascript)driver).executeScript(
         "localStorage.setItem('profiles', JSON.stringify([{  title: 'Selenium', hideComment: true, appendMode: '', 
             headers: [                        
               {enabled: true, name: 'token-1', value: 'value-1', comment: ''},
               {enabled: true, name: 'token-2', value: 'value-2', comment: ''}
             ],                          
             respHeaders: [],
             filters: []
          }]));");

Where token-1, value-1, token-2, value-2 are the request headers and values that are to be added.

5. Now navigate to the required web-application.

   driver.get("your-desired-website");

This solution allows you to add space in-between the images as well. It combines the best parts of all the existing solutions and doesn't add any ugly table borders.

<p align="center">
  <img alt="Light" src="https://...light.png" width="45%">
&nbsp; &nbsp; &nbsp; &nbsp;
  <img alt="Dark" src="https://...dark.png" width="45%">
</p>

The key is adding the   non-breaking space HTML entities, which you can add and remove in order to customize the spacing.

You can see this example live on GitHub here.

As David notes, his suggestion does not actually fulfill the OP's request, which was an email with subject and message. It doesn't work because most, maybe all, combinations of browsers plus e-mail clients do not accept the subject and body attributes of the mailto: URI when supplied as a <form>'s action.

But here's a working example:

HTML (with Bootstrap styles):

<p><input id="subject" type="text" placeholder="type your subject here" 
    class="form-control"></p>
<p><input id="message" type="text" placeholder="type your message here" 
    class="form-control"></p>
<p><a id="mail-link" class="btn btn-primary">Create email</a></p>

JavaScript (with jQuery):

<script type="text/javascript">
    function loadEvents() {
        var mailString;
        function updateMailString() {
            mailString = '?subject=' + encodeURIComponent($('#subject').val())
                + '&body=' + encodeURIComponent($('#message').val());
            $('#mail-link').attr('href',  'mailto:[email protected]' + mailString);
        }
        $( "#subject" ).focusout(function() { updateMailString(); });
        $( "#message" ).focusout(function() { updateMailString(); });
        updateMailString();
    }
</script>

Notes:

• The <form> element with associated action attribute is not used.
• The <input> element of type button is also not used.
  • <a> styled as a button (here using Bootstrap) replaces <input type="button">
  • focusout() with updateMailString() is necessary because the <a> tag's href attribute does not automatically update when the input fields' values change.
  • updateMailString() is also called when document is loaded in case the input fields are prepopulated.
• Also encodeURIComponent() is used to get characters such as the quotation mark (") across to Outlook.

In this approach, the mailto: URI is supplied (with subject and body attributes) in an a element's href tag. This works in all combinations of browsers and e-mail clients I have tested, which are recent (2015) versions of:

• Browsers: Firefox/Win&OSX, Chrome/Win&OSX, IE/Win, Safari/OSX&iOS, Opera/OSX
• E-mail clients: Outlook/Win, Mail.app/OSX&iOS, Sparrow/OSX

Bonus tip: In my use cases, I add some contextual text to the e-mail body. More often than not, I want that text to contain line breaks. %0D%0A (carriage return and linefeed) works in my tests.

If you are java 1.6 then the following can also be done:

import javax.tools.JavaCompiler; 
import javax.tools.ToolProvider; 

public class CompilerExample {

    public static void main(String[] args) {
        String fileToCompile = "/Users/rupas/VolatileExample.java";

        JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();

        int compilationResult = compiler.run(null, null, null, fileToCompile);

        if (compilationResult == 0) {
            System.out.println("Compilation is successful");
        } else {
            System.out.println("Compilation Failed");
        }
    }
}

Yes, pretty much. List<T> is a generic class. It supports storing values of a specific type without casting to or from object (which would have incurred boxing/unboxing overhead when T is a value type in the ArrayList case). ArrayList simply stores object references. As a generic collection, List<T> implements the generic IEnumerable<T> interface and can be used easily in LINQ (without requiring any Cast or OfType call).

ArrayList belongs to the days that C# didn't have generics. It's deprecated in favor of List<T>. You shouldn't use ArrayList in new code that targets .NET >= 2.0 unless you have to interface with an old API that uses it.

At least five answers for one generic question.

Depending on

• posix compliant: could work on poor systems with generic shell environments
• bash specific: using so called bashisms

and if you want

• simple ``in line'' question / answer (generic solutions)
• pretty formatted interfaces, like ncurses or more graphical using libgtk or libqt...
• use powerful readline history capability

1. POSIX generic solutions

You could use the read command, followed by if ... then ... else:

echo -n "Is this a good question (y/n)? "
read answer

# if echo "$answer" | grep -iq "^y" ;then

if [ "$answer" != "${answer#[Yy]}" ] ;then
    echo Yes
else
    echo No
fi

(Thanks to Adam Katz's comment: Replaced the test above with one that is more portable and avoids one fork:)

POSIX, but single key feature

But if you don't want the user to have to hit Return, you could write:

(Edited: As @JonathanLeffler rightly suggest, saving stty's configuration could be better than simply force them to sane.)

echo -n "Is this a good question (y/n)? "
old_stty_cfg=$(stty -g)
stty raw -echo ; answer=$(head -c 1) ; stty $old_stty_cfg # Careful playing with stty
if echo "$answer" | grep -iq "^y" ;then
    echo Yes
else
    echo No
fi

Note: This was tested under sh, bash, ksh, dash and busybox!

Same, but waiting explicitly for y or n:

#/bin/sh
echo -n "Is this a good question (y/n)? "
old_stty_cfg=$(stty -g)
stty raw -echo
answer=$( while ! head -c 1 | grep -i '[ny]' ;do true ;done )
stty $old_stty_cfg
if echo "$answer" | grep -iq "^y" ;then
    echo Yes
else
    echo No
fi

Using dedicated tools

There are many tools which were built using libncurses, libgtk, libqt or other graphical libraries. For example, using whiptail:

if whiptail --yesno "Is this a good question" 20 60 ;then
    echo Yes
else
    echo No
fi

Depending on your system, you may need to replace whiptail with another similiar tool:

dialog --yesno "Is this a good question" 20 60 && echo Yes

gdialog --yesno "Is this a good question" 20 60 && echo Yes

kdialog --yesno "Is this a good question" 20 60 && echo Yes

where 20 is height of dialog box in number of lines and 60 is width of the dialog box. These tools all have near same syntax.

DIALOG=whiptail
if [ -x /usr/bin/gdialog ] ;then DIALOG=gdialog ; fi
if [ -x /usr/bin/xdialog ] ;then DIALOG=xdialog ; fi
...
$DIALOG --yesno ...

2. Bash specific solutions

Basic in line method

read -p "Is this a good question (y/n)? " answer
case ${answer:0:1} in
    y|Y )
        echo Yes
    ;;
    * )
        echo No
    ;;
esac

I prefer to use case so I could even test for yes | ja | si | oui if needed...

in line with single key feature

Under bash, we can specify the length of intended input for for the read command:

read -n 1 -p "Is this a good question (y/n)? " answer

Under bash, read command accepts a timeout parameter, which could be useful.

read -t 3 -n 1 -p "Is this a good question (y/n)? " answer
[ -z "$answer" ] && answer="Yes"  # if 'yes' have to be default choice

3. Some tricks for dedicated tools

More sophisticated dialog boxes, beyond simple yes - no purposes:

dialog --menu "Is this a good question" 20 60 12 y Yes n No m Maybe

Progress bar:

dialog --gauge "Filling the tank" 20 60 0 < <(
    for i in {1..100};do
        printf "XXX\n%d\n%(%a %b %T)T progress: %d\nXXX\n" $i -1 $i
        sleep .033
    done
) 

Little demo:

#!/bin/sh
while true ;do
    [ -x "$(which ${DIALOG%% *})" ] || DIALOG=dialog
    DIALOG=$($DIALOG --menu "Which tool for next run?" 20 60 12 2>&1 \
            whiptail       "dialog boxes from shell scripts" >/dev/tty \
            dialog         "dialog boxes from shell with ncurses" \
            gdialog        "dialog boxes from shell with Gtk" \
            kdialog        "dialog boxes from shell with Kde" ) || exit
    clear;echo "Choosed: $DIALOG."
    for i in `seq 1 100`;do
        date +"`printf "XXX\n%d\n%%a %%b %%T progress: %d\nXXX\n" $i $i`"
        sleep .0125
      done | $DIALOG --gauge "Filling the tank" 20 60 0
    $DIALOG --infobox "This is a simple info box\n\nNo action required" 20 60
    sleep 3
    if $DIALOG --yesno  "Do you like this demo?" 20 60 ;then
        AnsYesNo=Yes; else AnsYesNo=No; fi
    AnsInput=$($DIALOG --inputbox "A text:" 20 60 "Text here..." 2>&1 >/dev/tty)
    AnsPass=$($DIALOG --passwordbox "A secret:" 20 60 "First..." 2>&1 >/dev/tty)
    $DIALOG --textbox /etc/motd 20 60
    AnsCkLst=$($DIALOG --checklist "Check some..." 20 60 12 \
        Correct "This demo is useful"        off \
        Fun        "This demo is nice"        off \
        Strong        "This demo is complex"        on 2>&1 >/dev/tty)
    AnsRadio=$($DIALOG --radiolist "I will:" 20 60 12 \
        " -1" "Downgrade this answer"        off \
        "  0" "Not do anything"                on \
        " +1" "Upgrade this anser"        off 2>&1 >/dev/tty)
    out="Your answers:\nLike: $AnsYesNo\nInput: $AnsInput\nSecret: $AnsPass"
    $DIALOG --msgbox "$out\nAttribs: $AnsCkLst\nNote: $AnsRadio" 20 60
  done

More sample? Have a look at Using whiptail for choosing USB device and USB removable storage selector: USBKeyChooser

5. Using readline's history

Example:

#!/bin/bash

set -i
HISTFILE=~/.myscript.history
history -c
history -r

myread() {
    read -e -p '> ' $1
    history -s ${!1}
}
trap 'history -a;exit' 0 1 2 3 6

while myread line;do
    case ${line%% *} in
        exit )  break ;;
        *    )  echo "Doing something with '$line'" ;;
      esac
  done

This will create a file .myscript.history in your $HOME directory, than you could use readline's history commands, like Up, Down, Ctrl+r and others.

Look at this tutorial or this one, they are both pretty simple. If you are interested in an alternative this is how you do file I/O in C.

Some things to keep in mind, use single quotes ' when dealing with single characters, and double " for strings. Also it is a bad habit to use global variables when not necessary.

Have fun!

insert into account_type_standard (account_type_Standard_id, tax_status_id, recipient_id)
select account_type_standard_seq.nextval,
   ts.tax_status_id, 
   ( select r.recipient_id
     from recipient r
     where r.recipient_code = ?
   )
from tax_status ts
where ts.tax_status_code = ?

Another idea worth mentioning, although it's an older topic, is creating a CDI producer to inject your logger so the mocking becomes easy. (And it also gives the advantage of not having to declare the "whole logger statement" anymore, but that's off-topic)

Example:

Creating the logger to inject:

public class CdiResources {
  @Produces @LoggerType
  public Logger createLogger(final InjectionPoint ip) {
      return Logger.getLogger(ip.getMember().getDeclaringClass());
  }
}

The qualifier:

@Qualifier
@Retention(RetentionPolicy.RUNTIME)
@Target({TYPE, METHOD, FIELD, PARAMETER})
public @interface LoggerType {
}

Using the logger in your production code:

public class ProductionCode {
    @Inject
    @LoggerType
    private Logger logger;

    public void logSomething() {
        logger.info("something");
    }
}

Testing the logger in your test code (giving an easyMock example):

@TestSubject
private ProductionCode productionCode = new ProductionCode();

@Mock
private Logger logger;

@Test
public void testTheLogger() {
   logger.info("something");
   replayAll();
   productionCode.logSomething();
}

Suppose you have an index on id, this will be lightning fast:

SELECT * FROM [MyTable] WHERE [id] > (SELECT MAX([id]) - 5 FROM [MyTable])

Try this:

>>> i = 3
>>> a = [1, 2, 3, 4]
>>> next(iter(a[i:]), 'fail')
4
>>> next(iter(a[i + 1:]), 'fail')
'fail'

In Unix, this works like a charm:

ffmpeg -i 00000.avi -vcodec copy -acodec copy -f null /dev/null 2>&1 \
                                          | grep 'frame=' | cut -f 2 -d ' '

This works:

function getBreakText($t) {
    return strtr($t, array('\\r\\n' => '<br>', '\\r' => '<br>', '\\n' => '<br>'));
}

Use this in your conda prompt:

python -m pip install xgboost

Since many of the fancy solutions above don't work with UWP and because I love Linq and functional approaches I pressent you my version to this problem. To escape the comparison when the first difference occures, I chose .FirstOrDefault()

public static bool CompareByteArrays(byte[] ba0, byte[] ba1) =>
    !(ba0.Length != ba1.Length || Enumerable.Range(1,ba0.Length)
        .FirstOrDefault(n => ba0[n] != ba1[n]) > 0);

Why would you want to use a hash?

You can just use a simple translation of your auto-increment value to an alphanumeric value. You can do that easily by using some base conversion. Say you character space (A-Z, a-z, 0-9, etc.) has 62 characters, convert the id to a base-40 number and use the characters as the digits.

Rails4 has some added datatypes for Postgres.

For example, railscast #400 names two of them:

Rails 4 has support for native datatypes in Postgres and we’ll show two of these here, although a lot more are supported: array and hstore. We can store arrays in a string-type column and specify the type for hstore.

Besides, you can also use cidr, inet and macaddr. For more information:

https://blog.engineyard.com/2013/new-in-rails-4

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

you can select a sibling element using jQuery

 <script type="text/javascript">
    $(document).ready(function(){
        $("selector").siblings().addClass("classname");
    });
 </script>

Demo here

Could do it with :contains() selector as well:

$('#toptitle:contains("Profil")').text("New word");

*In docker, an image is an immutable file that holds the source code and information needed for a docker app to run. It can exist independent of a container.

*Docker containers are virtualized environments created during runtime and require images to run. The docker website has an image that kind of shows this relationship:

Yes, you can use the two-chord hotkey (Ctrl+K, Ctrl+F if you're using the General profile) to format your selection.

Other formatting options are under menu Edit → Advanced, and like all Visual Studio commands, you can set your own hotkey via menu Tools → Options → Environment → Keyboard (the format selection command is called Edit.FormatSelection).

Formatting doesn't do anything with blank lines, but it will indent your code according to some rules that are usually slightly off from what you probably want.

You need to add a 640x1136 pixels PNG image ([email protected]) as a 4 inch default splash image of your project, and it will use extra spaces (without efforts on simple table based applications, games will require more efforts).

I've created a small UIDevice category in order to deal with all screen resolutions. You can get it here, but the code is as follows:

File UIDevice+Resolutions.h:

enum {
    UIDeviceResolution_Unknown           = 0,
    UIDeviceResolution_iPhoneStandard    = 1,    // iPhone 1,3,3GS Standard Display  (320x480px)
    UIDeviceResolution_iPhoneRetina4    = 2,    // iPhone 4,4S Retina Display 3.5"  (640x960px)
    UIDeviceResolution_iPhoneRetina5     = 3,    // iPhone 5 Retina Display 4"       (640x1136px)
    UIDeviceResolution_iPadStandard      = 4,    // iPad 1,2,mini Standard Display   (1024x768px)
    UIDeviceResolution_iPadRetina        = 5     // iPad 3 Retina Display            (2048x1536px)
}; typedef NSUInteger UIDeviceResolution;

@interface UIDevice (Resolutions)

- (UIDeviceResolution)resolution;

NSString *NSStringFromResolution(UIDeviceResolution resolution);

@end

File UIDevice+Resolutions.m:

#import "UIDevice+Resolutions.h"

@implementation UIDevice (Resolutions)

- (UIDeviceResolution)resolution
{
    UIDeviceResolution resolution = UIDeviceResolution_Unknown;
    UIScreen *mainScreen = [UIScreen mainScreen];
    CGFloat scale = ([mainScreen respondsToSelector:@selector(scale)] ? mainScreen.scale : 1.0f);
    CGFloat pixelHeight = (CGRectGetHeight(mainScreen.bounds) * scale);

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
        if (scale == 2.0f) {
            if (pixelHeight == 960.0f)
                resolution = UIDeviceResolution_iPhoneRetina4;
            else if (pixelHeight == 1136.0f)
                resolution = UIDeviceResolution_iPhoneRetina5;

        } else if (scale == 1.0f && pixelHeight == 480.0f)
            resolution = UIDeviceResolution_iPhoneStandard;

    } else {
        if (scale == 2.0f && pixelHeight == 2048.0f) {
            resolution = UIDeviceResolution_iPadRetina;

        } else if (scale == 1.0f && pixelHeight == 1024.0f) {
            resolution = UIDeviceResolution_iPadStandard;
        }
    }

    return resolution;
 }

 @end

This is how you need to use this code.

1) Add the above UIDevice+Resolutions.h & UIDevice+Resolutions.m files to your project

2) Add the line #import "UIDevice+Resolutions.h" to your ViewController.m

3) Add this code to check what versions of device you are dealing with

int valueDevice = [[UIDevice currentDevice] resolution];

    NSLog(@"valueDevice: %d ...", valueDevice);

    if (valueDevice == 0)
    {
        //unknow device - you got me!
    }
    else if (valueDevice == 1)
    {
        //standard iphone 3GS and lower
    }
    else if (valueDevice == 2)
    {
        //iphone 4 & 4S
    }
    else if (valueDevice == 3)
    {
        //iphone 5
    }
    else if (valueDevice == 4)
    {
        //ipad 2
    }
    else if (valueDevice == 5)
    {
        //ipad 3 - retina display
    }

Was looking at how to trust a certificate while using jenkins cli, and found https://issues.jenkins-ci.org/browse/JENKINS-12629 which has some recipe for that.

This will give you the certificate:

openssl s_client -connect ${HOST}:${PORT} </dev/null

if you are interested only in the certificate part, cut it out by piping it to:

| sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

and redirect to a file:

> ${HOST}.cert

Then import it using keytool:

keytool -import -noprompt -trustcacerts -alias ${HOST} -file ${HOST}.cert \
    -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}

In one go:

HOST=myhost.example.com
PORT=443
KEYSTOREFILE=dest_keystore
KEYSTOREPASS=changeme

# get the SSL certificate
openssl s_client -connect ${HOST}:${PORT} </dev/null \
    | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ${HOST}.cert

# create a keystore and import certificate
keytool -import -noprompt -trustcacerts \
    -alias ${HOST} -file ${HOST}.cert \
    -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}

# verify we've got it.
keytool -list -v -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS} -alias ${HOST}

Your css will only work in IE browser. And the css suggessted by hayk.mart will olny work in webkit browsers. And by using different css hacks you can't style your browsers scroll bars with a same result.

So, it is better to use a jQuery/Javascript plugin to achieve a cross browser solution with a same result.

Solution:

By Using jScrollPane a jQuery plugin, you can achieve a cross browser solution

See This Demo

just to offer up some variety. ds.oop is a nice way to declare classes with constructors in javascript. It supports every possible type of inheritance (Including 1 type that even c# does not support) as well as Interfaces which is nice.

var Color = ds.make.class({
    type: 'Color',
    constructor: function (r,g,b) { 
        this.r = r;                     /* now r,g, and b are available to   */
        this.g = g;                     /* other methods in the Color class  */
        this.b = b;                     
    }
});
var red = new Color(255,0,0);   // using the new keyword to instantiate the class

I have implemented callback/delegate support in Java using reflection. Details and working source are available on my website.

How It Works

We have a principle class named Callback with a nested class named WithParms. The API which needs the callback will take a Callback object as a parameter and, if neccessary, create a Callback.WithParms as a method variable. Since a great many of the applications of this object will be recursive, this works very cleanly.

With performance still a high priority to me, I didn't want to be required to create a throwaway object array to hold the parameters for every invocation - after all in a large data structure there could be thousands of elements, and in a message processing scenario we could end up processing thousands of data structures a second.

In order to be threadsafe the parameter array needs to exist uniquely for each invocation of the API method, and for efficiency the same one should be used for every invocation of the callback; I needed a second object which would be cheap to create in order to bind the callback with a parameter array for invocation. But, in some scenarios, the invoker would already have a the parameter array for other reasons. For these two reasons, the parameter array did not belong in the Callback object. Also the choice of invocation (passing the parameters as an array or as individual objects) belongs in the hands of the API using the callback enabling it to use whichever invocation is best suited to it's inner workings.

The WithParms nested class, then, is optional and serves two purposes, it contains the parameter object array needed for the callback invocations, and it provides 10 overloaded invoke() methods (with from 1 to 10 parameters) which load the parameter array and then invoke the callback target.

Look in C:\Program Files\dotnet\shared\Microsoft.NETCore.App to see which versions of the runtime have directories there. Source.

A lot of the answers here confuse the SDK with the Runtime, which are different.

Open the /etc/mysql/mysql.conf.d/mysqld.cnf file and comment the following line:

#bind-address = 127.0.0.1

Set oShell = CreateObject ("WScript.Shell") 
oShell.run "cmd.exe /C copy ""S:Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

I know the original question lists Cygwin, but here is the solution for CentOS:

just to save my own deductions from all this is (for saving DBMS_OUTPUT output on the client, using sqlplus):

• no matter if i use Toad/with polling or sqlplus, for a long running script with occasional dbms_output.put_line commands, i will get the output in the end of the script execution
• set serveroutput on; and dbms_output.enable(); should be present in the script
• to save the output SPOOL command was not enough to get the DBMS_OUTPUT lines printed to a file - had to use the usual > windows CMD redirection. the passwords etc. can be given to the empty prompt, after invoking sqlplus. also the "/" directives and the "exit;" command should be put either inside the script, or given interactively as the password above (unless it is specified during the invocation of sqlplus)

If you got here because you're using the new ASP.NET Identity UserManager, what you're actually looking for is the RoleManager:

var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));

roleManager will give you access to see if the role exists, create, etc, plus it is created for the UserManager

Joe Kington's excellent answer is already 4 years old, Matplotlib has incrementally changed (in particular, the introduction of the cycler module) and the new major release, Matplotlib 2.0.x, has introduced stylistic differences that are important from the point of view of the colors used by default.

The color of individual lines

The color of individual lines (as well as the color of different plot elements, e.g., markers in scatter plots) is controlled by the color keyword argument,

plt.plot(x, y, color=my_color)

my_color is either

• a tuple of floats representing RGB or RGBA (as(0.,0.5,0.5)),
• a RGB/RGBA hex string (as "#008080" (RGB) or "#008080A0"),
• a string representation of a float value in [0, 1] inclusive for gray level (e.g., '0.6'),
• a short color name (as "k" for black, possible values in "bgrcmykw"),
• a long color name (as "teal") --- aka HTML color name (in the docs also X11/CSS4 color name),
• a name from the xkcd color survey, prefixed with 'xkcd:' (e.g., 'xkcd:barbie pink'),
• a color from the Tableau Colors in the default 'T10' categorical palette, (e.g., 'tab:blue', 'tab:olive'),
• a reference to a color of the current color cycle (as "C3", i.e., the letter "C" followed by a single digit in "0-9").

The color cycle

By default, different lines are plotted using different colors, that are defined by default and are used in a cyclic manner (hence the name color cycle).

The color cycle is a property of the axes object, and in older releases was simply a sequence of valid color names (by default a string of one character color names, "bgrcmyk") and you could set it as in

my_ax.set_color_cycle(['kbkykrkg'])

(as noted in a comment this API has been deprecated, more on this later).

In Matplotlib 2.0 the default color cycle is ["#1f77b4", "#ff7f0e", "#2ca02c", "#d62728", "#9467bd", "#8c564b", "#e377c2", "#7f7f7f", "#bcbd22", "#17becf"], the Vega category10 palette.

_{(the image is a screenshot from https://vega.github.io/vega/docs/schemes/)}

The cycler module: composable cycles

The following code shows that the color cycle notion has been deprecated

In [1]: from matplotlib import rc_params

In [2]: rc_params()['axes.color_cycle']
/home/boffi/lib/miniconda3/lib/python3.6/site-packages/matplotlib/__init__.py:938: UserWarning: axes.color_cycle is deprecated and replaced with axes.prop_cycle; please use the latter.
  warnings.warn(self.msg_depr % (key, alt_key))
Out[2]: 
['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd',
 '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf']

Now the relevant property is the 'axes.prop_cycle'

In [3]: rc_params()['axes.prop_cycle']
Out[3]: cycler('color', ['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd', '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf'])

Previously, the color_cycle was a generic sequence of valid color denominations, now by default it is a cycler object containing a label ('color') and a sequence of valid color denominations. The step forward with respect to the previous interface is that it is possible to cycle not only on the color of lines but also on other line attributes, e.g.,

In [5]: from cycler import cycler

In [6]: new_prop_cycle = cycler('color', ['k', 'r']) * cycler('linewidth', [1., 1.5, 2.])

In [7]: for kwargs in new_prop_cycle: print(kwargs)
{'color': 'k', 'linewidth': 1.0}
{'color': 'k', 'linewidth': 1.5}
{'color': 'k', 'linewidth': 2.0}
{'color': 'r', 'linewidth': 1.0}
{'color': 'r', 'linewidth': 1.5}
{'color': 'r', 'linewidth': 2.0}

As you have seen, the cycler objects are composable and when you iterate on a composed cycler what you get, at each iteration, is a dictionary of keyword arguments for plt.plot.

You can use the new defaults on a per axes object ratio,

my_ax.set_prop_cycle(new_prop_cycle)

or you can install temporarily the new default

plt.rc('axes', prop_cycle=new_prop_cycle)

or change altogether the default editing your .matplotlibrc file.

Last possibility, use a context manager

with plt.rc_context({'axes.prop_cycle': new_prop_cycle}):
    ...

to have the new cycler used in a group of different plots, reverting to defaults at the end of the context.

The doc string of the cycler() function is useful, but the (not so much) gory details about the cycler module and the cycler() function, as well as examples, can be found in the fine docs.

The above answer doesn't work. You have to set DeliveryMethod = SmtpDeliveryMethod.Network or it will come back with a "client was not authenticated" error. Also it's always a good idea to put a timeout.

Revised code:

using System.Net.Mail;
using System.Net;

var fromAddress = new MailAddress("[email protected]", "From Name");
var toAddress = new MailAddress("[email protected]", "To Name");
const string fromPassword = "password";
const string subject = "test";
const string body = "Hey now!!";

var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
    Timeout = 20000
};
using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body
})
{
    smtp.Send(message);
}

The awk is ok. I'm guessing the file is from a windows system and has a CR (^m ascii 0x0d) on the end of the line.

This will cause the cursor to go to the start of the line after $2.

Use dos2unix or vi with :se ff=unix to get rid of the CRs.

you can use if statement like below

select CONCAT(if(affiliate_name is null ,'',affiliate_name),'- ',if(model is null ,'',affiliate_name)) as model from devices

If key is present table.put(key, val) will just overwrite the value else it'll create a new entry. Poof! and you are done. :)

you can get the value from a map by using key is table.get(key); That's about it

This will work for your case:

sonar.exclusions=**/src/java/dig/ ** , **/src/java/test/dig/ **

This should remove the first element, and then you can return the remaining:

var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
    _x000D_
myarray.shift();_x000D_
alert(myarray);

As others have suggested, you could also use slice(1);

var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
  _x000D_
alert(myarray.slice(1));

This will squash second commit into the first one:

A-B-C-... -> AB-C-...

git filter-branch --commit-filter '
    if [ "$GIT_COMMIT" = <sha1ofA> ];
    then
        skip_commit "$@";
    else
        git commit-tree "$@";
    fi
' HEAD

Commit message for AB will be taken from B (although I'd prefer from A).

Has the same effect as Uwe Kleine-König's answer, but works for non-initial A as well.

In my case, I'm using Windows 10 in Spanish and this version mixes English and Spanish directory names. My problem was that the desktop directory has this name for some commands and escritorio to others. I believe that npm cannot resolve this. My solution was to simply change to another directory starting from C:\ different to my home directory.

Edit 2020-06-15

Since data.table 1.12.4 (Oct 2019), data.table gains two functions to facilitate this: nafill and setnafill.

nafill operates on columns:

cols = c('a', 'b')
y[ , (cols) := lapply(.SD, nafill, fill=0), .SDcols = cols]

setnafill operates on tables (the replacements happen by-reference/in-place)

setnafill(y, cols=cols, fill=0)
# print y to show the effect
y[]

This will also be more efficient than the other options; see ?nafill for more, the last-observation-carried-forward (LOCF) and next-observation-carried-backward (NOCB) versions of NA imputation for time series.

This will work for your data.table version:

for (col in c("a", "b")) y[is.na(get(col)), (col) := 0]

Alternatively, as David Arenburg points out below, you can use set (side benefit - you can use it either on data.frame or data.table):

for (col in 1:2) set(x, which(is.na(x[[col]])), col, 0)

Short answer but did you have Skype open? This interferes specifically with ASP.NET by default (and localhosts in general) using port:80.

In Windows: Go to Tools -> Options -> Advanced -> Connection and uncheck the box "use port 80 and 443 as alternatives for incoming connections".

jQuery:

var inputs = $('#foo');

inputs.each(function(){
          this.style.textTransform = 'uppercase';
       })
       .keyup(function(){
          this.value = this.value.toUpperCase();
       });

1. Set the input's style to capitals (so user doesn't see the change)
2. Automatically adjust the value (so the user doesn't have to hold shift or use caps lock)

A solution that does not add extra leading or trailing whitespace:

awk '{ for(i=4; i<NF; i++) printf "%s",$i OFS; if(NF) printf "%s",$NF; printf ORS}'

### Example ###
$ echo '1 2 3 4 5 6 7' |
  awk '{for(i=4;i<NF;i++)printf"%s",$i OFS;if(NF)printf"%s",$NF;printf ORS}' |
  tr ' ' '-'
4-5-6-7

Sudo_O proposes an elegant improvement using the ternary operator NF?ORS:OFS

$ echo '1 2 3 4 5 6 7' |
  awk '{ for(i=4; i<=NF; i++) printf "%s",$i (i==NF?ORS:OFS) }' |
  tr ' ' '-'
4-5-6-7

EdMorton gives a solution preserving original whitespaces between fields:

$ echo '1   2 3 4   5    6 7' |
  awk '{ sub(/([^ ]+ +){3}/,"") }1' |
  tr ' ' '-'
4---5----6-7

BinaryZebra also provides two awesome solutions:
^{(these solutions even preserve trailing spaces from original string)}

$ echo -e ' 1   2\t \t3     4   5   6 7 \t 8\t ' |
  awk -v n=3 '{ for ( i=1; i<=n; i++) { sub("^["FS"]*[^"FS"]+["FS"]+","",$0);} } 1 ' |
  sed 's/ /./g;s/\t/->/g;s/^/"/;s/$/"/'
"4...5...6.7.->.8->."

$ echo -e ' 1   2\t \t3     4   5   6 7 \t 8\t ' |
  awk -v n=3 '{ print gensub("["FS"]*([^"FS"]+["FS"]+){"n"}","",1); }' |
  sed 's/ /./g;s/\t/->/g;s/^/"/;s/$/"/'
"4...5...6.7.->.8->."

The solution given by larsr in the comments is almost correct:

$ echo '1 2 3 4 5 6 7' | 
  awk '{for (i=3;i<=NF;i++) $(i-2)=$i; NF=NF-2; print $0}' | tr  ' ' '-'
3-4-5-6-7

This is the fixed and parametrized version of larsr solution:

$ echo '1 2 3 4 5 6 7' | 
  awk '{for(i=n;i<=NF;i++)$(i-(n-1))=$i;NF=NF-(n-1);print $0}' n=4 | tr ' ' '-'
4-5-6-7

All other answers before Sep-2013 are nice but add extra spaces:

• Example of answer adding extra leading spaces:

  $ echo '1 2 3 4 5 6 7' | 
    awk '{$1=$2=$3=""}1' | 
    tr  ' ' '-'
  ---4-5-6-7
  

• Example of answer adding extra trailing space

  $ echo '1 2 3 4 5 6 7' | 
    awk '{for(i=4;i<=13;i++)printf "%s ",$i;printf "\n"}' | 
    tr ' ' '-'
  4-5-6-7-------
  

If you want a one-liner solution (ignoring imports) that only requires O(max(n, m)) work for inputs of length n and m, not O(n * m) work, you can do so with the itertools module:

from itertools import filterfalse

main_list = list(filterfalse(set(list_1).__contains__, list_2))

This takes advantage of the functional functions taking a callback function on construction, allowing it to create the callback once and reuse it for every element without needing to store it somewhere (because filterfalse stores it internally); list comprehensions and generator expressions can do this, but it's ugly.†

That gets the same results in a single line as:

main_list = [x for x in list_2 if x not in list_1]

with the speed of:

set_1 = set(list_1)
main_list = [x for x in list_2 if x not in set_1]

Of course, if the comparisons are intended to be positional, so:

list_1 = [1, 2, 3]
list_2 = [2, 3, 4]

should produce:

main_list = [2, 3, 4]

(because no value in list_2 has a match at the same index in list_1), you should definitely go with Patrick's answer, which involves no temporary lists or sets (even with sets being roughly O(1), they have a higher "constant" factor per check than simple equality checks) and involves O(min(n, m)) work, less than any other answer, and if your problem is position sensitive, is the only correct solution when matching elements appear at mismatched offsets.

†: The way to do the same thing with a list comprehension as a one-liner would be to abuse nested looping to create and cache value(s) in the "outermost" loop, e.g.:

main_list = [x for set_1 in (set(list_1),) for x in list_2 if x not in set_1]

which also gives a minor performance benefit on Python 3 (because now set_1 is locally scoped in the comprehension code, rather than looked up from nested scope for each check; on Python 2 that doesn't matter, because Python 2 doesn't use closures for list comprehensions; they operate in the same scope they're used in).

You're missing an ending anchor.

if(Regex.IsMatch(myString, "^[A-Za-z]{2}[0-9]{2}\z")) {
    // ...
}

Here's a demo.

EDIT: If you can have anything between an initial 2 letters and a final 2 numbers:

if(Regex.IsMatch(myString, @"^[A-Za-z]{2}.*\d{2}\z")) {
    // ...
}

Here's a demo.

That's a known issue. Currently you have to use a workaround like shown in your question.

This is working as intended. When the change event is emitted ngModelChange (the (...) part of [(ngModel)] hasn't updated the bound model yet:

<input type="checkbox"  (ngModelChange)="myModel=$event" [ngModel]="mymodel">

Try this:

if (items.elementAt(1) instanceof Double) {
   sum.add( i, items.elementAt(1));
}

Search for EnableOptimizations keyword in your project

So if you find

BundleTable.EnableOptimizations = true;

turn it false.

This does disable minification, And it also disables bundling entirely

NSArray *myArray = [NSArray arrayWithObjects:[NSNumber numberWithInt:1], [NSNumber numberWithInt:2], [NSNumber numberWithInt:3]];

Update for new Objective-C syntax:

NSArray *myArray = @[@1, @2, @3];

Those two declarations are identical from the compiler's perspective.

if you're just wanting to use an integer in a string for putting into a textbox or something:

int myInteger = 5;
NSString* myNewString = [NSString stringWithFormat:@"%i", myInteger];

Made a category like mxcl, but this is slightly faster.

My testing shows ~15% improvement (I could be wrong, feel free to compare the two yourself).

Basically I take the portion of the array thats in front of the object and the portion behind and combine them. Thus excluding the element.

- (NSArray *)prefix_arrayByRemovingObject:(id)object 
{
    if (!object) {
        return self;
    }

    NSUInteger indexOfObject = [self indexOfObject:object];
    NSArray *firstSubArray = [self subarrayWithRange:NSMakeRange(0, indexOfObject)];
    NSArray *secondSubArray = [self subarrayWithRange:NSMakeRange(indexOfObject + 1, self.count - indexOfObject - 1)];
    NSArray *newArray = [firstSubArray arrayByAddingObjectsFromArray:secondSubArray];

    return newArray;
}

The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

This takes care of nulls

var body = JObject.Parse("anyjsonString");

body?.SelectToken("path-string-prop")?.ToString();

body?.SelectToken("path-double-prop")?.ToObject<double>();

I think it is better to copy files from your local computer, because if files number or file size is very big, copying process could be interrupted if your current ssh session would be lost (broken pipe or whatever).

If you have configured ssh key to connect to your remote server, you could use the following command:

rsync -avP -e "ssh -i /home/local_user/ssh/key_to_access_remote_server.pem" remote_user@remote_host.ip:/home/remote_user/file.gz /home/local_user/Downloads/

Where v option is --verbose, a option is --archive - archive mode, P option same as --partial - keep partially transferred files, e option is --rsh=COMMAND - specifying the remote shell to use.

new List<int> { 1, 3, 5 }.ForEach(Console.WriteLine);

I have melted @Timmmm answer and @Manuel. If you do this solution, you will not get a Run Out Of Memory Exception.

This method retrieves the image orientation:

private static final int ROTATION_DEGREES = 90;
// This means 512 px
private static final Integer MAX_IMAGE_DIMENSION = 512;

public static int getOrientation(Uri photoUri) throws IOException {

    ExifInterface exif = new ExifInterface(photoUri.getPath());
    int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);

    switch (orientation) {
        case ExifInterface.ORIENTATION_ROTATE_90:
            orientation = ROTATION_DEGREES;
            break;
        case ExifInterface.ORIENTATION_ROTATE_180:
            orientation = ROTATION_DEGREES * 2;
            break;
        case ExifInterface.ORIENTATION_ROTATE_270:
            orientation = ROTATION_DEGREES * 3;
            break;
        default:
            // Default case, image is not rotated
            orientation = 0;
    }

    return orientation;
}

Therefore, you would use this method to resize image before load it on memory. In that way, you will not get a Memory Exception.

public static Bitmap getCorrectlyOrientedImage(Context context, Uri photoUri) throws IOException {
    InputStream is = context.getContentResolver().openInputStream(photoUri);
    BitmapFactory.Options dbo = new BitmapFactory.Options();
    dbo.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(is, null, dbo);
    is.close();

    int rotatedWidth, rotatedHeight;
    int orientation = getOrientation(photoUri);

    if (orientation == 90 || orientation == 270) {
        rotatedWidth = dbo.outHeight;
        rotatedHeight = dbo.outWidth;
    } else {
        rotatedWidth = dbo.outWidth;
        rotatedHeight = dbo.outHeight;
    }

    Bitmap srcBitmap;
    is = context.getContentResolver().openInputStream(photoUri);
    if (rotatedWidth > MAX_IMAGE_DIMENSION || rotatedHeight > MAX_IMAGE_DIMENSION) {
        float widthRatio = ((float) rotatedWidth) / ((float) MAX_IMAGE_DIMENSION);
        float heightRatio = ((float) rotatedHeight) / ((float) MAX_IMAGE_DIMENSION);
        float maxRatio = Math.max(widthRatio, heightRatio);

        // Create the bitmap from file
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inSampleSize = (int) maxRatio;
        srcBitmap = BitmapFactory.decodeStream(is, null, options);
    } else {
        srcBitmap = BitmapFactory.decodeStream(is);
    }
    is.close();

    // if the orientation is not 0, we have to do a rotation.
    if (orientation > 0) {
        Matrix matrix = new Matrix();
        matrix.postRotate(orientation);

        srcBitmap = Bitmap.createBitmap(srcBitmap, 0, 0, srcBitmap.getWidth(),
                srcBitmap.getHeight(), matrix, true);
    }

    return srcBitmap;
}

This works perfectly for me. I hope this helps somebody else

Just do the following and it will work fine.

1. When the error appears instead of clicking on 'finish' , click on 'x'.It will ask to to re initialize. Take the recommended option.
2. After it reconfiguration it will take back to the main screen. Just go to
   Configure -> Project Defaults -> Project Structure and copy paste or browse (appData folder may be hidden) to location C: / Users / user / AppData / Local / android / SDK.
3. Finish and try creating project again. Will work like charm !! ;)

Try x-1 in (i for i in range(x)) for large x values, which uses a generator comprehension to avoid invoking the range.__contains__ optimisation.

Though this aims to run jobs beside a running process in a container via Docker's exec interface, this may be of interest for you.

I've written a daemon that observes containers and schedules jobs, defined in their metadata, on them. Example:

version: '2'

services:
  wordpress:
    image: wordpress
  mysql:
    image: mariadb
    volumes:
      - ./database_dumps:/dumps
    labels:
      deck-chores.dump.command: sh -c "mysqldump --all-databases > /dumps/dump-$$(date -Idate)"
      deck-chores.dump.interval: daily

'Classic', cron-like configuration is also possible.

The biggest "gotcha" with trying to detect touch is on hybrid devices that support both touch and the trackpad/mouse. Even if you're able to correctly detect whether the user's device supports touch, what you really need to do is detect what input device the user is currently using. There's a detailed write up of this challenge and a possible solution here.

Basically the approach to figuring out whether a user just touched the screen or used a mouse/ trackpad instead is to register both a touchstart and mouseover event on the page:

document.addEventListener('touchstart', functionref, false) // on user tap, "touchstart" fires first
document.addEventListener('mouseover', functionref, false) // followed by mouse event, ie: "mouseover"

A touch action will trigger both of these events, though the former (touchstart) always first on most devices. So counting on this predictable sequence of events, you can create a mechanism that dynamically adds or removes a can-touch class to the document root to reflect the current input type of the user at this moment on the document:

;(function(){
    var isTouch = false //var to indicate current input type (is touch versus no touch) 
    var isTouchTimer 
    var curRootClass = '' //var indicating current document root class ("can-touch" or "")
     
    function addtouchclass(e){
        clearTimeout(isTouchTimer)
        isTouch = true
        if (curRootClass != 'can-touch'){ //add "can-touch' class if it's not already present
            curRootClass = 'can-touch'
            document.documentElement.classList.add(curRootClass)
        }
        isTouchTimer = setTimeout(function(){isTouch = false}, 500) //maintain "istouch" state for 500ms so removetouchclass doesn't get fired immediately following a touch event
    }
     
    function removetouchclass(e){
        if (!isTouch && curRootClass == 'can-touch'){ //remove 'can-touch' class if not triggered by a touch event and class is present
            isTouch = false
            curRootClass = ''
            document.documentElement.classList.remove('can-touch')
        }
    }
     
    document.addEventListener('touchstart', addtouchclass, false) //this event only gets called when input type is touch
    document.addEventListener('mouseover', removetouchclass, false) //this event gets called when input type is everything from touch to mouse/ trackpad
})();

More details here.

This is similar to some of the other answers, but is compact and avoids the conversion to dictionary if you already have a list.

Given a ComboBox "combobox" on a windows form and a class SomeClass with the string type property Name,

List<SomeClass> list = new List<SomeClass>();

combobox.DisplayMember = "Name";
combobox.DataSource = list;

Which means that combobox.SelectedItem is a SomeClass object from list, and each item in combobox will be displayed using its property Name.

You can read the selected item using

SomeClass someClass = (SomeClass)combobox.SelectedItem;

I'm using:

use this method if you are more curious about performance and time complexity. in this method i have divided string in two part and sort it in length/2 times loop iteration.

let str = "abcdefghijklmnopqrstuvwxyz"_x000D_
_x000D_
function reverse(str){_x000D_
let store = ""_x000D_
let store2 = ""_x000D_
_x000D_
for(let i=str.length/2;i>=0;i--){_x000D_
  if(str.length%2!==0){_x000D_
     store += str.charAt(i) _x000D_
  store2 += str.slice((str.length/2)+1, str.length).charAt(i)_x000D_
  }else{_x000D_
store += str.charAt(i-1) _x000D_
  store2 += str.slice((str.length/2), str.length).charAt(i)_x000D_
  }_x000D_
  _x000D_
}_x000D_
return store2+store_x000D_
}_x000D_
_x000D_
console.log(reverse(str))

it is not optimal but we can think like this.

Okay so you are trying to get a bitmap from a file? Title says URL. Anyways, when you are getting files from external storage in Android you should never use a direct path. Instead call getExternalStorageDirectory() like so:

File bitmapFile = new File(Environment.getExternalStorageDirectory() + "/" + PATH_TO_IMAGE);
Bitmap bitmap = BitmapFactory.decodeFile(bitmapFile);

getExternalStorageDirectory() gives you the path to the SD card. Also you need to declare the WRITE_EXTERNAL_STORAGE permission in the Manifest.

I know this is an old question, but none of the answers worked for me, because I wanted to reliably (always be able to) set the cell into edit mode when possibly executing other events like Toolbar Button clicks, menu selections, etc. that may affect the default focus after those events return. I ended up needing a timer and invoke. The following code is in a new component derived from DataGridView. This code allows me to simply make a call to myXDataGridView.CurrentRow_SelectCellFocus(myDataPropertyName); anytime I want to arbitrarily set a databound cell to edit mode (assuming the cell is Not in ReadOnly mode).

// If the DGV does not have Focus prior to a toolbar button Click, 
// then the toolbar button will have focus after its Click event handler returns.
// To reliably set focus to the DGV, we need to time it to happen After event handler procedure returns.

private string m_SelectCellFocus_DataPropertyName = "";
private System.Timers.Timer timer_CellFocus = null;

public void CurrentRow_SelectCellFocus(string sDataPropertyName)
{
  // This procedure is called by a Toolbar Button's Click Event to select and set focus to a Cell in the DGV's Current Row.
  m_SelectCellFocus_DataPropertyName = sDataPropertyName;
  timer_CellFocus = new System.Timers.Timer(10);
  timer_CellFocus.Elapsed += TimerElapsed_CurrentRowSelectCellFocus;
  timer_CellFocus.Start();
}


void TimerElapsed_CurrentRowSelectCellFocus(object sender, System.Timers.ElapsedEventArgs e)
{
  timer_CellFocus.Stop();
  timer_CellFocus.Elapsed -= TimerElapsed_CurrentRowSelectCellFocus;
  timer_CellFocus.Dispose();
  // We have to Invoke the method to avoid raising a threading error
  this.Invoke((MethodInvoker)delegate
  {
    Select_Cell(m_SelectCellFocus_DataPropertyName);
  });
}


private void Select_Cell(string sDataPropertyName)
{
  /// When the Edit Mode is Enabled, set the initial cell to the Description
  foreach (DataGridViewCell dgvc in this.SelectedCells) 
  {
    // Clear previously selected cells
    dgvc.Selected = false; 
  }
  foreach (DataGridViewCell dgvc in this.CurrentRow.Cells)
  {
    // Select the Cell by its DataPropertyName
    if (dgvc.OwningColumn.DataPropertyName == sDataPropertyName)
    {
      this.CurrentCell = dgvc;
      dgvc.Selected = true;
      this.Focus();
      return;
    }
  }
}

You may want to take a look at XCopy or RoboCopy which are pretty comprehensive solutions for nearly all file copy operations on Windows.

4.19.4 The instanceof operator

The instanceof operator requires the left operand to be of type Any, an object type, or a type parameter type, and the right operand to be of type Any or a subtype of the 'Function' interface type. The result is always of the Boolean primitive type.

So you could use

mySprite instanceof Sprite;

Note that this operator is also in ActionScript but it shouldn't be used there anymore:

The is operator, which is new for ActionScript 3.0, allows you to test whether a variable or expression is a member of a given data type. In previous versions of ActionScript, the instanceof operator provided this functionality, but in ActionScript 3.0 the instanceof operator should not be used to test for data type membership. The is operator should be used instead of the instanceof operator for manual type checking, because the expression x instanceof y merely checks the prototype chain of x for the existence of y (and in ActionScript 3.0, the prototype chain does not provide a complete picture of the inheritance hierarchy).

TypeScript's instanceof shares the same problems. As it is a language which is still in its development I recommend you to state a proposal of such facility.

Found a solution.

1) Go to where your SDK is located that android studio/eclipse is using. If you are using Android studio, go to extras\android\m2repository\com\android\support\. If you are using eclipse, go to \extras\android\support\

2) See what folders you have, for me I had gridlayout-v7, support-v4 and support-v13.

3) click into support-v4 and see what number the following folder is, mine was named 13.0

Since you are using "com.android.support:support-v4:18.0.+", change this to reflect what version you have, for example I have support-v4 so first part v4 stays the same. Since the next path is 13.0, change your 18.0 to:

"com.android.support:support-v4:13.0.+"

This worked for me, hope it helps!

Update:

I noticed I had android studio set up with the wrong SDK which is why originally had difficulty updating! The path should be C:\Users\Username\AppData\Local\Android\android-sdk\extras\

Also note, if your SDK is up to date, the code will be:

"com.android.support:support-v4:19.0.+"

Your problem is that you're converting the button into an HTML snippet when you add it to the table, but that snippet is not the same object as the one that has the click handler on it.

$("#myButton").click(function () {
    var test = $('<button>Test</button>').click(function () {
        alert('hi');
    });

    $("#nodeAttributeHeader").css('display', 'table-row'); // NB: changed

    var tr = $('<tr>').insertBefore('#addNodeTable tr:last');
    var td = $('<td>').append(test).appendTo(tr);
});

If running tests on the repository from a seperate assembly, then make sure your Hibernate.cfg.xml is set to output always in the bin directory of said assembly. This wasn't happening for us and we got the above error in certain circumstances.

Disclaimer: This might be a slightly esoteric bit of advice, given that it's a direct result of how we structure our repository integration test assemblies (i.e. we have a symbolic link from each test assembly to a single Hibernate.xfg.xml)

For accounting applications it's very common to store the values as integers (some even go so far as to say it's the only way). To get an idea, take the amount of the transactions (let's suppose $100.23) and multiple by 100, 1000, 10000, etc. to get the accuracy you need. So if you only need to store cents and can safely round up or down, just multiply by 100. In my example, that would make 10023 as the integer to store. You'll save space in the database and comparing two integers is much easier than comparing two floats. My $0.02.

I've had success with this solution. It's almost like Patrick's, with a little twist. You can use these expressions separately or in sequence. If the parameter is blank, it will be ignored and all values for the column that your searching will be displayed, including NULLS.

SELECT * FROM MyTable
WHERE 
    --check to see if @param1 exists, if @param1 is blank, return all
    --records excluding filters below
(Col1 LIKE '%' + @param1 + '%' OR @param1 = '')
AND
    --where you want to search multiple columns using the same parameter
    --enclose the first 'OR' expression in braces and enclose the entire 
    --expression 
((Col2 LIKE '%' + @searchString + '%' OR Col3 LIKE '%' + @searchString + '%') OR @searchString = '')
AND
    --if your search requires a date you could do the following
(Cast(DateCol AS DATE) BETWEEN CAST(@dateParam AS Date) AND CAST(GETDATE() AS DATE) OR @dateParam = '')

If you are using vscodevim extension, then you can harness the power of vim keyboard moves. When you are on a line that you would like to bookmark, in normal mode, you can type:

m {a-z A-Z} for a possible 52 bookmarks within a file. Small letter alphabets are for bookmarks within a single file. Capital letters preserve their marks across files.

To navigate to a bookmark from within any file, you then need to hit ' {a-z A-Z}. I don't think these bookmarks stay across different VSCode sessions though.

More vim shortcuts here.

I wasn't sure what you wanted to do about the Event column, but if you want to keep that as well, how about

isIDmax <- with(dd, ave(Value, ID, FUN=function(x) seq_along(x)==which.max(x)))==1
group[isIDmax, ]

#   ID Value Event
# 3  1     5     2
# 7  2    17     2
# 9  3     5     2

Here we use ave to look at the "Value" column for each "ID". Then we determine which value is the maximal and then turn that into a logical vector we can use to subset the original data.frame.

You can do it pretty simply using recursion and a forced error...

Also, pardon my horridly sloppy c++ code.

void print_number(uint number)
{
    try
    {
        print_number(number-1);
    }
    catch(int e) {}
    printf("%d", number+1);
}

void main()
{
    print_number(1001);
}

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

Perhaps adobe's flash player detection kit could be helpful here?

  StringBuffer sBuffer = new StringBuffer();
  Pattern p = Pattern.compile("[0-9]+.[0-9]*|[0-9]*.[0-9]+|[0-9]+");
  Matcher m = p.matcher(str);
  while (m.find()) {
    sBuffer.append(m.group());
  }
  return sBuffer.toString();

This is for extracting numbers retaining the decimal

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

Developer efficiency matters much more to me in scenarios where both bash and Python are sensible choices.

Some tasks lend themselves well to bash, and others to Python. It also isn't unusual for me to start something as a bash script and change it to Python as it evolves over several weeks.

A big advantage Python has is in corner cases around filename handling, while it has glob, shutil, subprocess, and others for common scripting needs.

All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.

return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);

Getting the first line is trivially easy. For the last line, presuming you know an approximate upper bound on the line length, os.lseek some amount from SEEK_END find the second to last line ending and then readline() the last line.

Awesome answers! I was able to use Spannable to build rainbow colored text (so this could be repeated for any array of colors). Here's my method, if it helps anyone:

private Spannable buildRainbowText(String pack_name) {
        int[] colors = new int[]{Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE};
        Spannable word = new SpannableString(pack_name);
        for(int i = 0; i < word.length(); i++) {
            word.setSpan(new ForegroundColorSpan(colors[i]), i, i+1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
        return word;
    }

And then I just setText(buildRainboxText(pack_name)); Note that all of the words I pass in are under 15 characters and this just repeats 5 colors 3 times - you'd want to adjust the colors/length of the array for your usage!

You can use multi stage build to build containers This is the approach you can take :-

Stage 1 building an image with ssh

FROM ubuntu as sshImage
LABEL stage=sshImage
ARG SSH_PRIVATE_KEY
WORKDIR /root/temp

RUN apt-get update && \
    apt-get install -y git npm 

RUN mkdir /root/.ssh/ &&\
    echo "${SSH_PRIVATE_KEY}" > /root/.ssh/id_rsa &&\
    chmod 600 /root/.ssh/id_rsa &&\
    touch /root/.ssh/known_hosts &&\
    ssh-keyscan github.com >> /root/.ssh/known_hosts

COPY package*.json ./

RUN npm install

RUN cp -R node_modules prod_node_modules

Stage 2: build your container

FROM node:10-alpine

RUN mkdir -p /usr/app

WORKDIR /usr/app

COPY ./ ./

COPY --from=sshImage /root/temp/prod_node_modules ./node_modules

EXPOSE 3006

CMD ["npm", "run", "dev"] 

add env attribute in your compose file:

   environment:
      - SSH_PRIVATE_KEY=${SSH_PRIVATE_KEY}

then pass args from build script like this:

docker-compose build --build-arg SSH_PRIVATE_KEY="$(cat ~/.ssh/id_rsa)"

And remove the intermediate container it for security. This Will help you cheers.

EF Core 5.0

This loooong-awaited feature is available in EF Core 5.0! This is from the weekly status updates:

var query = context.Set<Customer>().Where(c => c.City == city);
Console.WriteLine(query.ToQueryString())

results in this output when using the SQL Server database provider:

DECLARE p0 nvarchar(4000) = N'London';

SELECT [c].[CustomerID], [c].[Address], [c].[City], [c].[CompanyName],
[c].[ContactName], [c].[ContactTitle], [c].[Country], [c].[Fax], [c].[Phone],
[c].[PostalCode], [c].[Region]
FROM [Customers] AS [c]
WHERE [c].[City] = @__city_0

Notice that declarations for parameters of the correct type are also included in the output. This allows copy/pasting to SQL Server Management Studio, or similar tools, such that the query can be executed for debugging/analysis.

woohoo!!!

A simple and flexible offline recognition on Android is implemented by CMUSphinx, an open source speech recognition toolkit. It works purely offline, fast and configurable It can listen continuously for keyword, for example.

You can find latest code and tutorial here.

Update in 2019: Time goes fast, CMUSphinx is not that accurate anymore. I recommend to try Kaldi toolkit instead. The demo is here.

When I tried to create something simillar to inbox floating action button i thought about creating own custom component.

It would be simple frame layout with fixed height (to contain expanded menu) containing FAB button and 3 more placed under the FAB. when you click on FAB you just simply animate other buttons to translate up from under the FAB.

There are some libraries which do that (for example https://github.com/futuresimple/android-floating-action-button), but it's always more fun if you create it by yourself :)

You can easily make lists of lists

list1 <- list(a = 2, b = 3)
list2 <- list(c = "a", d = "b")
mylist <- list(list1, list2)

mylist is now a list that contains two lists. To access list1 you can use mylist[[1]]. If you want to be able to something like mylist$list1 then you need to do somethingl like

mylist <- list(list1 = list1, list2 = list2)
# Now you can do the following
mylist$list1

Edit: To reply to your edit. Just use double bracket indexing

a <- list_all[[1]]
a[[1]]
#[1] 1
a[[2]]
#[1] 2

$("#id option").each(function()
{
    $(this).prop('selected', true);
});

Although, the CORRECT way is to set the DOM property of the element, like so:

$("#id option").each(function(){
    $(this).attr('selected', true);
});

From Ruby API:

require_relative complements the builtin method require by allowing you to load a file that is relative to the file containing the require_relative statement.

When you use require to load a file, you are usually accessing functionality that has been properly installed, and made accessible, in your system. require does not offer a good solution for loading files within the project’s code. This may be useful during a development phase, for accessing test data, or even for accessing files that are "locked" away inside a project, not intended for outside use.

For example, if you have unit test classes in the "test" directory, and data for them under the test "test/data" directory, then you might use a line like this in a test case:

require_relative "data/customer_data_1" 

Since neither "test" nor "test/data" are likely to be in Ruby’s library path (and for good reason), a normal require won’t find them. require_relative is a good solution for this particular problem.

You may include or omit the extension (.rb or .so) of the file you are loading.

path must respond to to_str.

You can find the documentation at http://extensions.rubyforge.org/rdoc/classes/Kernel.html

You can pass parameters into your initial java process with -D:

java -cp <classpath> -Dkey1=value -Dkey2=value ...

In case you're using YAML and Twig for translations in Symfony, and want to use multi-line translations in Javascript, a carriage return is added right after the translation. So even the following code:

var javascriptVariable = "{{- 'key'|trans -}}";

Which has the following yml translation:

key: >
    This is a
    multi line 
    translation.

Will still result into the following code in html:

var javascriptVariable = "This is a multi line translation.
";

So, the minus sign in Twig does not solve this. The solution is to add this minus sign after the greater than sign in yml:

key: >-
    This is a
    multi line 
    translation.

Will have the proper result, multi line translation on one line in Twig:

var javascriptVariable = "This is a multi line translation.";

You can't use the 'out' variable (nor any of the other "predeclared" scriptlet variables) inside directives.

The JSP page gets translated by your webserver into a Java servlet. Inside tomcats, for instance, everything inside scriptlets (which start "<%"), along with all the static HTML, gets translated into one giant Java method which writes your page, line by line, to a JspWriter instance called "out". This is why you can use the "out" parameter directly in scriptlets. Directives, on the other hand (which start with "<%!") get translated as separate Java methods.

As an example, a very simple page (let's call it foo.jsp):

<html>
    <head/>
    <body>
        <%!
            String someOutput() {
                return "Some output";
            }
        %>
        <% someOutput(); %>
    </body>
</html>

would end up looking something like this (with a lot of the detail ignored for clarity):

public final class foo_jsp
{
    // This is where the request comes in
    public void _jspService(HttpServletRequest request, HttpServletResponse response) 
        throws IOException, ServletException
    {
        // JspWriter instance is gotten from a factory
        // This is why you can use 'out' directly in scriptlets
        JspWriter out = ...; 

        // Snip

        out.write("<html>");
        out.write("<head/>");
        out.write("<body>");
        out.write(someOutput()); // i.e. write the results of the method call
        out.write("</body>");
        out.write("</html>");
    }

    // Directive gets translated as separate method - note
    // there is no 'out' variable declared in scope
    private String someOutput()
    {
        return "Some output";
    }
}

You shouldn't launch as an IIS server. check your launch setting, make sure it switched to your project name( change this name in your launchSettings.json file ), not the IIS.

No plugin necessary for just this task. Cobbled this together from a couple other scripts:

$('INPUT[type="file"]').change(function () {
    var ext = this.value.match(/\.(.+)$/)[1];
    switch (ext) {
        case 'jpg':
        case 'jpeg':
        case 'png':
        case 'gif':
            $('#uploadButton').attr('disabled', false);
            break;
        default:
            alert('This is not an allowed file type.');
            this.value = '';
    }
});

The trick here is to set the upload button to disabled unless and until a valid file type is selected.

use DIRECTORY option.

Documentation here: http://docs.oracle.com/cd/E11882_01/server.112/e22490/dp_import.htm#SUTIL907

  DIRECTORY

  Default: DATA_PUMP_DIR

  Purpose

  Specifies the default location in which the import job can find the dump file set and where it should create log and SQL files.

  Syntax and Description

  DIRECTORY=directory_object
  The directory_object is the name of a database directory object (not the file path of an actual directory). Upon installation, privileged users have access to a default directory object named DATA_PUMP_DIR. Users with access to the default DATA_PUMP_DIR directory object do not need to use the DIRECTORY parameter at all.

  A directory object specified on the DUMPFILE, LOGFILE, or SQLFILE parameter overrides any directory object that you specify for the DIRECTORY parameter. You must have Read access to the directory used for the dump file set and Write access to the directory used to create the log and SQL files.

  Example

  The following is an example of using the DIRECTORY parameter. You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. See "FULL".

  > impdp hr DIRECTORY=dpump_dir1 DUMPFILE=expfull.dmp 
  LOGFILE=dpump_dir2:expfull.log
  This command results in the import job looking for the expfull.dmp dump file in the directory pointed to by the dpump_dir1 directory object. The dpump_dir2 directory object specified on the LOGFILE parameter overrides the DIRECTORY parameter so that the log file is written to dpump_dir2.

Note: If you're using AngularJS, then in addition to changing the step value, you may have to set ng-model-options="{updateOn: 'blur change'}" on the html input.

The reason for this is in order to have the validators run less often, as they are preventing the user from entering a decimal point. This way, the user can type in a decimal point and the validators go into effect after the user blurs.

Below are two simple query using which you can check index created on a table in Oracle.

select index_name
  from dba_indexes

Use the format() function with a '02x' format.

>>> format(255, '02x')
'ff'
>>> format(2, '02x')
'02'

The 02 part tells format() to use at least 2 digits and to use zeros to pad it to length, x means lower-case hexadecimal.

The Format Specification Mini Language also gives you X for uppercase hex output, and you can prefix the field width with # to include a 0x or 0X prefix (depending on wether you used x or X as the formatter). Just take into account that you need to adjust the field width to allow for those extra 2 characters:

>>> format(255, '02X')
'FF'
>>> format(255, '#04x')
'0xff'
>>> format(255, '#04X')
'0XFF'

Token Based (Security / Authentication)

means that In order for us to prove that we’ve access we first have to receive the token. In a real life scenario, the token could be an access card to building, it could be the key to the lock to your house. In order for you to retrieve a key card for your office or the key to your home, you first need to prove who you are, and that you in fact do have access to that token. It could be something as simple as showing someone your ID or giving them a secret password. So imagine I need to get access to my office. I go down to the security office, I show them my ID, and they give me this token, which lets me into the building. Now I have unrestricted access to do whatever I want inside the building, as long as I have my token with me.

What’s the benefit of token based security?

If we think back on the insecure API, what we had to do in that case was that we had to provide our password for everything that we wanted to do.

Imagine that every time we enter a door in our office, we have to give everyone sitting next to the door our password. Now that would be pretty bad, because that means that anyone inside our office could take our password and impersonate us, and that’s pretty bad. Instead, what we do is that we retrieve the token, of course together with password, but we retrieve that from one person. And then we can use this token wherever we want inside the building. Of course if we lose the token, we have the same problem as if someone else knew our password, but that leads us into things like how do we make sure that if we lose the token, we can revoke the access, and maybe the token shouldn’t live for longer than 24hours, so the next day that we come to the office, we need to show our ID again. But still, there’s just one person that we show the ID to, and that’s the security guard sitting where we retrieve the tokens.

Say your bug fix branch is called bugfix and you want to merge it into master:

git checkout master
git merge --squash bugfix
git commit

This will take all the commits from the bugfix branch, squash them into 1 commit, and merge it with your master branch.

Explanation:

git checkout master

Switches to your master branch.

git merge --squash bugfix

Takes all commits from the bugfix branch and groups it for a 1 commit with your current branch.
(no merge commit appears; you could resolve conflicts manually before following commit)

git commit

Creates a single commit from the merged changes.

Omitting the -m parameter lets you modify a draft commit message containing every message from your squashed commits before finalizing your commit.

I assume you want to pass the Order ID in. So:

CREATE PROCEDURE [dbo].[Procedure_Name]
(
    @OrderID INT
) AS
BEGIN
    Declare @OrderItemID AS INT
    DECLARE @AppointmentID AS INT
    DECLARE @PurchaseOrderID AS INT
    DECLARE @PurchaseOrderItemID AS INT
    DECLARE @SalesOrderID AS INT
    DECLARE @SalesOrderItemID AS INT

    SET @OrderItemID = (SELECT OrderItemID FROM [OrderItem] WHERE OrderID = @OrderID)
    SET @AppointmentID = (SELECT AppoinmentID FROM [Appointment] WHERE OrderID = @OrderID)
    SET @PurchaseOrderID = (SELECT PurchaseOrderID FROM [PurchaseOrder] WHERE OrderID = @OrderID)
END

Try

sudo -su db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \(1995\)

instead of print $image; you should go for print "<img src=<?$image;?>>"

and note that $image should contain the path of your image.

So, If you are only storing the name of your image in database then instead of that you have to store the full path of your image in the database like /root/user/Documents/image.jpeg.

Use mavenCentral() or jcenter() adding in the build.gradle file the script:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'   
    }
}

You can code like two input box inside one div

<div class="input-group">
            <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
            <input style="width:50% " class="form-control " placeholder="first name"  name="firstname" type="text" />
            <input style="width:50% " class="form-control " placeholder="lastname"  name="lastname" type="text" />
        </div>

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

I had a case where the error was thrown by a

$state.go('');

Which is obvious. I guess this can help someone in future.

You can use the Where to filter and Select to get the desired value.

MyList.Where(i=>i.name == yourName).Select(j=>j.value);

1. A set is an unordered data structure, so it does not preserve the insertion order.

2. This depends on your requirements. If you have an normal list, and want to remove some set of elements while preserving the order of the list, you can do this with a list comprehension:

   >>> a = [1, 2, 20, 6, 210]
   >>> b = set([6, 20, 1])
   >>> [x for x in a if x not in b]
   [2, 210]
   

   If you need a data structure that supports both fast membership tests and preservation of insertion order, you can use the keys of a Python dictionary, which starting from Python 3.7 is guaranteed to preserve the insertion order:

   >>> a = dict.fromkeys([1, 2, 20, 6, 210])
   >>> b = dict.fromkeys([6, 20, 1])
   >>> dict.fromkeys(x for x in a if x not in b)
   {2: None, 210: None}
   

   b doesn't really need to be ordered here – you could use a set as well. Note that a.keys() - b.keys() returns the set difference as a set, so it won't preserve the insertion order.

   In older versions of Python, you can use collections.OrderedDict instead:

   >>> a = collections.OrderedDict.fromkeys([1, 2, 20, 6, 210])
   >>> b = collections.OrderedDict.fromkeys([6, 20, 1])
   >>> collections.OrderedDict.fromkeys(x for x in a if x not in b)
   OrderedDict([(2, None), (210, None)])
   

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

We had a very similar issue whereby a client's website was trying to connect to our Web API service and getting that same message. This started happening completely out of the blue when there had been no code changes or Windows updates on the server where IIS was running.

In our case it turned out that the calling website was using a version of .Net that only supported TLS 1.0 and for some reason the server where our IIS was running stopped appeared to have stopped accepting TLS 1.0 calls. To diagnose that we had to explicitly enable TLS via the registry on the IIS's server and then restart that server. These are the reg keys:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.0\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.0\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.1\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.1\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.2\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.2\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

If that doesn't do it, you could also experiment with adding the entry for SSL 2.0:


    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Client]
    "DisabledByDefault"=dword:00000000
    "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server]
    "DisabledByDefault"=dword:00000000
    "Enabled"=dword:00000001

My answer to another question here has this powershell script that we used to add the entries:

NOTE: Enabling old security protocols is not a good idea, the right answer in our case was to get the client website to update it's code to use TLS 1.2, but the registry entries above can help diagnose the issue in the first place.

After utilizing some of the answers above, don't forget that after an apt install, a total reboot might be in order.

The RemoveInvalidXmlChars method provided by Irishman does not support surrogate characters. To test it, use the following example:

static void Main()
{
    const string content = "\v\U00010330";

    string newContent = RemoveInvalidXmlChars(content);

    Console.WriteLine(newContent);
}

This returns an empty string but it shouldn't! It should return "\U00010330" because the character U+10330 is a valid XML character.

To support surrogate characters, I suggest using the following method:

public static string RemoveInvalidXmlChars(string text)
{
    if (string.IsNullOrEmpty(text))
        return text;

    int length = text.Length;
    StringBuilder stringBuilder = new StringBuilder(length);

    for (int i = 0; i < length; ++i)
    {
        if (XmlConvert.IsXmlChar(text[i]))
        {
            stringBuilder.Append(text[i]);
        }
        else if (i + 1 < length && XmlConvert.IsXmlSurrogatePair(text[i + 1], text[i]))
        {
            stringBuilder.Append(text[i]);
            stringBuilder.Append(text[i + 1]);
            ++i;
        }
    }

    return stringBuilder.ToString();
}

Here's an answer to my own question. I combined the answers from the various results to write a class that pretty prints XML.

No guarantees on how it responds with invalid XML or large documents.

See this:

The difference between Response.Write() and Response.Output.Write() in ASP.NET. The short answer is that the latter gives you String.Format-style output and the former doesn't. The long answer follows.

In ASP.NET the Response object is of type HttpResponse and when you say Response.Write you're really saying (basically) HttpContext.Current.Response.Write and calling one of the many overloaded Write methods of HttpResponse.

Response.Write then calls .Write() on it's internal TextWriter object:

public void Write(object obj){ this._writer.Write(obj);} 

HttpResponse also has a Property called Output that is of type, yes, TextWriter, so:

public TextWriter get_Output(){ return this._writer; } 

Which means you can do the Response whatever a TextWriter will let you. Now, TextWriters support a Write() method aka String.Format, so you can do this:

Response.Output.Write("Scott is {0} at {1:d}", "cool",DateTime.Now);

But internally, of course, this is happening:

public virtual void Write(string format, params object[] arg)
{ 
this.Write(string.Format(format, arg)); 
}

The good option is to use AdminClient as below before starting to produce or consume the messages

private static final int ADMIN_CLIENT_TIMEOUT_MS = 5000;           
 try (AdminClient client = AdminClient.create(properties)) {
            client.listTopics(new ListTopicsOptions().timeoutMs(ADMIN_CLIENT_TIMEOUT_MS)).listings().get();
        } catch (ExecutionException ex) {
            LOG.error("Kafka is not available, timed out after {} ms", ADMIN_CLIENT_TIMEOUT_MS);
            return;
        }

Move semantics is about transferring resources rather than copying them when nobody needs the source value anymore.

In C++03, objects are often copied, only to be destroyed or assigned-over before any code uses the value again. For example, when you return by value from a function—unless RVO kicks in—the value you're returning is copied to the caller's stack frame, and then it goes out of scope and is destroyed. This is just one of many examples: see pass-by-value when the source object is a temporary, algorithms like sort that just rearrange items, reallocation in vector when its capacity() is exceeded, etc.

When such copy/destroy pairs are expensive, it's typically because the object owns some heavyweight resource. For example, vector<string> may own a dynamically-allocated memory block containing an array of string objects, each with its own dynamic memory. Copying such an object is costly: you have to allocate new memory for each dynamically-allocated blocks in the source, and copy all the values across. Then you need deallocate all that memory you just copied. However, moving a large vector<string> means just copying a few pointers (that refer to the dynamic memory block) to the destination and zeroing them out in the source.

It's one of the common mistake everybody make while working with jQuery, Basically $ is an alias of jQuery() so when you try to call/access it before declaring the function will endup throwing this error.

Reasons might be

1) Path to jQuery library you included is not correct.

2) Added library after the script were you see that error

To solve this

Load the jquery library beginning of all your javascript files/scripts.

<script src="https://code.jquery.com/jquery-3.3.1.js"></script>

Please make use of the code below to display images inline:

<img style='vertical-align:middle;' src='somefolder/icon.gif'>
<div style='vertical-align:middle; display:inline;'>
Your text here
</div>

The code:

public class Test {
    public static void main(String args[]) {
        String string = args[0];
        System.out.println("last character: " +
                           string.substring(string.length() - 1)); 
    }
}

The output of java Test abcdef:

last character: f

Foreign key and check constraints have the concept of being trusted or untrusted, as well as being enabled and disabled. See the MSDN page for ALTER TABLE for full details.

WITH CHECK is the default for adding new foreign key and check constraints, WITH NOCHECK is the default for re-enabling disabled foreign key and check constraints. It's important to be aware of the difference.

Having said that, any apparently redundant statements generated by utilities are simply there for safety and/or ease of coding. Don't worry about them.

Just treat the ES6 class name the same as you would have treated the constructor name in the ES5 way. They are one and the same.

The ES6 syntax is just syntactic sugar and creates exactly the same underlying prototype, constructor function and objects.

So, in your ES6 example with:

// animal.js
class Animal {
    ...
}

var a = new Animal();

module.exports = {Animal: Animal};

You can just treat Animal like the constructor of your object (the same as you would have done in ES5). You can export the constructor. You can call the constructor with new Animal(). Everything is the same for using it. Only the declaration syntax is different. There's even still an Animal.prototype that has all your methods on it. The ES6 way really does create the same coding result, just with fancier/nicer syntax.

On the import side, this would then be used like this:

const Animal = require('./animal.js').Animal;

let a = new Animal();

This scheme exports the Animal constructor as the .Animal property which allows you to export more than one thing from that module.

If you don't need to export more than one thing, you can do this:

// animal.js
class Animal {
    ...
}

module.exports = Animal;

And, then import it with:

const Animal = require('./animal.js');

let a = new Animal();

background: #13486d; /* for non-css3 browsers */
background-image: -webkit-gradient(linear, left top, left bottom, from(#9dc3c3),   to(#13486d));  background: -moz-linear-gradient(top,  #9dc3c3,  #13486d);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#9dc3c3', endColorstr='#13486d');
background-repeat:no-repeat;

You say that the date is used in connection with web services, so I assume that is serialized into a string at some point.

If this is the case, you should take a look at the setTimeZone method of the DateFormat class. This dictates which time zone that will be used when printing the time stamp.

A simple example:

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));

Calendar cal = Calendar.getInstance();
String timestamp = formatter.format(cal.getTime());

Looping through all the files in the folder is relatively easy:
