Using url-loader, described here (SurviveJS - Loading Images), you can then use in your code :

import LogoImg from 'YOUR_PATH/logo.png';

and

<img src={LogoImg}/>

Edit: a precision, images are inlined in the js archive with this technique. It can be worthy for small images, but use the technique wisely.

>>> r = range(1, 4)
>>> 1 in r
True
>>> 2 in r
True
>>> 3 in r
True
>>> 4 in r
False
>>> 5 in r
False
>>> 0 in r
False

The easiest way may be to use plotti.co - the microservice I created exactly for this. It depends on how you get the data, but general usage pattern is including an SVG image into your html like

<object data="http://plotti.co/FSktKOvATQ8H/plot.svg" type="image/svg+xml"/>

and feeding your data in a GET request to your hash (or using a (new Image(1,1)).src=... JavaScript method from same or any other page) like this:

http://plotti.co/FSktKOvATQ8H?d=1,2,3

setting it up locally is also straightforward

A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label

See this link for more on the differences between a TextBlock and other Controls

Try this code:

<code>

    <a href="#" class="button" > HOME </a>

    <style type="text/css">

        .button { background-color: #00CCFF; padding: 8px 16px; display: inline-block; text-decoration: none; color: #FFFFFF border-radius: 3px;}

        .button:hover { background-color: #0066FF; }

    </style>

</code>

I'm not sure why this hasn't come up yet but why don't you use ℃ (?) or ℉ (?) for Celsius and Fahrenheit respectively!

While not recommended, you can also disable SSL cert validation alltogether:

import javax.net.ssl.*;
import java.security.SecureRandom;
import java.security.cert.X509Certificate;

public class SSLTool {

  public static void disableCertificateValidation() {
    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] { 
      new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() { 
          return new X509Certificate[0]; 
        }
        public void checkClientTrusted(X509Certificate[] certs, String authType) {}
        public void checkServerTrusted(X509Certificate[] certs, String authType) {}
    }};

    // Ignore differences between given hostname and certificate hostname
    HostnameVerifier hv = new HostnameVerifier() {
      public boolean verify(String hostname, SSLSession session) { return true; }
    };

    // Install the all-trusting trust manager
    try {
      SSLContext sc = SSLContext.getInstance("SSL");
      sc.init(null, trustAllCerts, new SecureRandom());
      HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
      HttpsURLConnection.setDefaultHostnameVerifier(hv);
    } catch (Exception e) {}
  }
}

you can use position(text in text) in order by for ordering the sequence

There is also OkHttp, which is an HTTP client that’s efficient by default:

• HTTP/2 support allows all requests to the same host to share a socket.
• Connection pooling reduces request latency (if HTTP/2 isn’t available).
• Transparent GZIP shrinks download sizes.
• Response caching avoids the network completely for repeat requests.

First create an instance of OkHttpClient:

OkHttpClient client = new OkHttpClient();

Then, prepare your GET request:

Request request = new Request.Builder()
      .url(url)
      .build();

finally, use OkHttpClient to send prepared Request:

Response response = client.newCall(request).execute();

For more details, you can consult the OkHttp's documentation

Another method utilizing the dplyr package:

library(dplyr)
df <- mtcars %>%
        filter(mpg > 25)

Without the chain (%>%) operator:

library(dplyr)
df <- filter(mtcars, mpg > 25)

An alternate solution of @kender

import os
os.path.dirname(os.path.normpath(yourpath))

where yourpath is the path you want the parent for.

But this solution is not perfect, since it will not handle the case where yourpath is an empty string, or a dot.

This other solution will handle more nicely this corner case:

import os
os.path.normpath(os.path.join(yourpath, os.pardir))

Here the outputs for every case that can find (Input path is relative):

os.path.dirname(os.path.normpath('a/b/'))          => 'a'
os.path.normpath(os.path.join('a/b/', os.pardir))  => 'a'

os.path.dirname(os.path.normpath('a/b'))           => 'a'
os.path.normpath(os.path.join('a/b', os.pardir))   => 'a'

os.path.dirname(os.path.normpath('a/'))            => ''
os.path.normpath(os.path.join('a/', os.pardir))    => '.'

os.path.dirname(os.path.normpath('a'))             => ''
os.path.normpath(os.path.join('a', os.pardir))     => '.'

os.path.dirname(os.path.normpath('.'))             => ''
os.path.normpath(os.path.join('.', os.pardir))     => '..'

os.path.dirname(os.path.normpath(''))              => ''
os.path.normpath(os.path.join('', os.pardir))      => '..'

os.path.dirname(os.path.normpath('..'))            => ''
os.path.normpath(os.path.join('..', os.pardir))    => '../..'

Input path is absolute (Linux path):

os.path.dirname(os.path.normpath('/a/b'))          => '/a'
os.path.normpath(os.path.join('/a/b', os.pardir))  => '/a'

os.path.dirname(os.path.normpath('/a'))            => '/'
os.path.normpath(os.path.join('/a', os.pardir))    => '/'

os.path.dirname(os.path.normpath('/'))             => '/'
os.path.normpath(os.path.join('/', os.pardir))     => '/'

On my machine, port is in /opt/local/bin/port - try typing that into a terminal on its own.

In my case I had to set MaxHeight and replace IsEnabled="False" by IsReadOnly="True"

I did this as an experiment to reset the value to 0 as I want my first identity column to be 0 and it's working.

dbcc CHECKIDENT(MOVIE,RESEED,0)
dbcc CHECKIDENT(MOVIE,RESEED,-1)
DBCC CHECKIDENT(MOVIE,NORESEED)

The best way to do this is with the following code:

 Button button = (Button)findViewById(R.id.btn_register);
 button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //do your fancy method
            }
        });

As far as I understand, you have more than one form tag in your web page that causes the problem. Make sure you have only one server-side form tag for each page.

For me as I have already xampp on 127.0.0.1 and django on 127.0.1.1 and i kept trying adding hosts

ALLOWED_HOSTS = ['127.0.0.1', 'localhost', 'www.yourdomain.com', '*', '127.0.1.1']

and i got the same error or (400) bad request

so I change the url to 127.0.1.1:(the used port)/project and voila !

you have to check what is your virtual network address, for me as i use bitnami django stack 2.2.3-1 on Linux i can check which port django is using. if you have an error ( 400 bad request ) then i guess django on different virtual network .. good luck

I put the following in my .gvimrc file, which searches up the tree from any point for a tags file when gvim starts:

function SetTags()
    let curdir = getcwd()

    while !filereadable("tags") && getcwd() != "/"
        cd ..
    endwhile

    if filereadable("tags")
        execute "set tags=" . getcwd() . "/tags"
    endif

    execute "cd " . curdir
endfunction

call SetTags()

I then periodically regenerate a tags file at the top of my source tree with a script that looks like:

#!/bin/bash

find . -regex ".*\.\(c\|h\|hpp\|cc\|cpp\)" -print | ctags --totals --recurse --extra="+qf" --fields="+i" -L -

I had a similar challenge, but in my case, we had developed one version of the codebase in repo A, then cloned that into a new repo, repo B, for the new version of the product. After fixing some bugs in repo A, we needed to FI the changes into repo B. Ended up doing the following:

1. Adding a remote to repo B that pointed to repo A (git remote add...)
2. Pulling the current branch (we were not using master for bug fixes) (git pull remoteForRepoA bugFixBranch)
3. Pushing merges to github

Worked a treat :)

This works for me perfectly without any external API, just native Java hidden feature :)

import com.sun.management.OperatingSystemMXBean;
...
OperatingSystemMXBean osBean = ManagementFactory.getPlatformMXBean(
                OperatingSystemMXBean.class);
// What % CPU load this current JVM is taking, from 0.0-1.0
System.out.println(osBean.getProcessCpuLoad());

// What % load the overall system is at, from 0.0-1.0
System.out.println(osBean.getSystemCpuLoad());

As @jwalkerjr mentioned, you should be disposing of connections in code (if connection pooling is enabled, they are just returned to the connection pool). The prescribed way to do this is using the 'using' statement:

// Execute stored proc to read data from repository
using (SqlConnection conn = new SqlConnection(this.connectionString))
{
    using (SqlCommand cmd = conn.CreateCommand())
    {
        cmd.CommandText = "LoadFromRepository";
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@ID", fileID);

        conn.Open();
        using (SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection))
        {
            if (rdr.Read())
            {
                filename = SaveToFileSystem(rdr, folderfilepath);
            }
        }
    }
}

in package.json:

{
  ...
  "scripts": {
    "start": "NODE_ENV=production node ./app"
  }
  ...
}

then run in terminal:

npm start

Streams are EventEmitters so you can listen to certain events. As you said there is a finish event for request (previously end).

 var stream = request(...).pipe(...);
 stream.on('finish', function () { ... });

For more information about which events are available you can check the stream documentation page.

There is no solution that works for all use cases. If you use the $request->get('_route') method, or its variants, it will return '_internal' for cases where forwarding took place.

If you need a solution that works even with forwarding, you have to use the new RequestStack service, that arrived in 2.4, but this will break ESI support:

$requestStack = $container->get('request_stack');
$masterRequest = $requestStack->getMasterRequest(); // this is the call that breaks ESI
if ($masterRequest) {
    echo $masterRequest->attributes->get('_route');
}

You can make a twig extension out of this if you need it in templates.

Accuracy is also important.

What option 3 does is basically replace all the but any whitespaces with a +1 and then evaluates this to count up the 1's giving you the word count.

It's the most accurate and fastest method of the four that I've done here.

Please note it is slower than return str.split(" ").length; but it's accurate when compared to Microsoft Word.

See file ops/s and returned word count below.

This way works for me, (using Spring Boot version 2.0.1. RELEASE):

@Query("SELECT u.username FROM User u WHERE u.username LIKE %?1%")
List<String> findUsersWithPartOfName(@Param("username") String username);

Explaining: The ?1, ?2, ?3 etc. are place holders the first, second, third parameters, etc. In this case is enough to have the parameter is surrounded by % as if it was a standard SQL query but without the single quotes.

I've always used .place() for my tkinter widgets. place syntax

You can specify the size of it just by changing the keyword arguments!

Of course, you will have to call .place() again if you want to change it.

Simplest way (simple collect - supports parallel streams):

public static <T> Stream<T> reverse(Stream<T> stream) {
    return stream
            .collect(Collector.of(
                    () -> new ArrayDeque<T>(),
                    ArrayDeque::addFirst,
                    (q1, q2) -> { q2.addAll(q1); return q2; })
            )
            .stream();
}

Advanced way (supports parallel streams in an ongoing way):

public static <T> Stream<T> reverse(Stream<T> stream) {
    Objects.requireNonNull(stream, "stream");

    class ReverseSpliterator implements Spliterator<T> {
        private Spliterator<T> spliterator;
        private final Deque<T> deque = new ArrayDeque<>();

        private ReverseSpliterator(Spliterator<T> spliterator) {
            this.spliterator = spliterator;
        }

        @Override
        @SuppressWarnings({"StatementWithEmptyBody"})
        public boolean tryAdvance(Consumer<? super T> action) {
            while(spliterator.tryAdvance(deque::addFirst));
            if(!deque.isEmpty()) {
                action.accept(deque.remove());
                return true;
            }
            return false;
        }

        @Override
        public Spliterator<T> trySplit() {
            // After traveling started the spliterator don't contain elements!
            Spliterator<T> prev = spliterator.trySplit();
            if(prev == null) {
                return null;
            }

            Spliterator<T> me = spliterator;
            spliterator = prev;
            return new ReverseSpliterator(me);
        }

        @Override
        public long estimateSize() {
            return spliterator.estimateSize();
        }

        @Override
        public int characteristics() {
            return spliterator.characteristics();
        }

        @Override
        public Comparator<? super T> getComparator() {
            Comparator<? super T> comparator = spliterator.getComparator();
            return (comparator != null) ? comparator.reversed() : null;
        }

        @Override
        public void forEachRemaining(Consumer<? super T> action) {
            // Ensure that tryAdvance is called at least once
            if(!deque.isEmpty() || tryAdvance(action)) {
                deque.forEach(action);
            }
        }
    }

    return StreamSupport.stream(new ReverseSpliterator(stream.spliterator()), stream.isParallel());
}

Note you can quickly extends to other type of streams (IntStream, ...).

Testing:

// Use parallel if you wish only
revert(Stream.of("One", "Two", "Three", "Four", "Five", "Six").parallel())
    .forEachOrdered(System.out::println);

Results:

Six
Five
Four
Three
Two
One

Additional notes: The simplest way it isn't so useful when used with other stream operations (the collect join breaks the parallelism). The advance way doesn't have that issue, and it keeps also the initial characteristics of the stream, for example SORTED, and so, it's the way to go to use with other stream operations after the reverse.

Too bad we're kind of forced to tell the compiler the obvious:

Subclass(): base() {}
Subclass(int x): base(x) {}
Subclass(int x,y): base(x,y) {}

I only need to do 3 constructors in 12 subclasses, so it's no big deal, but I'm not too fond of repeating that on every subclass, after being used to not having to write it for so long. I'm sure there's a valid reason for it, but I don't think I've ever encountered a problem that requires this kind of restriction.

Or you can use Stream API for 1 character or a String starting in Java 1.8:

public class ASCIIConversion {
    public static void main(String[] args) {
        String text = "adskjfhqewrilfgherqifvehwqfjklsdbnf";
        text.chars()
                .forEach(System.out::println);
    }
}

In case you want to improve the commit message with header and body after you created the commit, you can reword it. This approach is more useful because you know what the code does only after you wrote it.

git rebase -i origin/master

Then, your commits will appear:

pick e152ce2 Update framework
pick ffcf91e Some magic
pick fa672e1 Update comments

Select the commit you want to reword and save.

pick e152ce2 Update framework
reword ffcf91e Some magic
pick fa672e1 Update comments

Now, you have the opportunity to add header and body, where the first line will be the header.

Setting the .collapsing CSS transitions to none as mentioned in the accepted answer removed the animation. But this — in Firefox and Chromium for me — creates an unwanted visual issue on collapse of the navbar.

For instance, visit the Bootstrap navbar example and add the CSS from the accepted answer:

.collapsing {
     -webkit-transition: none;
     transition: none;
}

What I currently see is when the navbar collapses, the bottom border of the navbar momentarily becomes two pixels instead of one, then disconcertingly jumps back to one. Using jQuery, this artifact doesn't appear.

Here is the solution for API < 21 and above

Drawable drawable = yourEditText.getBackground(); // get current EditText drawable 
drawable.setColorFilter(Color.GREEN, PorterDuff.Mode.SRC_ATOP); // change the drawable color

if(Build.VERSION.SDK_INT > 16) {
    yourEditText.setBackground(drawable); // set the new drawable to EditText
}else{
    yourEditText.setBackgroundDrawable(drawable); // use setBackgroundDrawable because setBackground required API 16
}

Hope it help

While other answers perfectly explained the question I will add some real life examples converting tensors to numpy array:

Example: Shared storage

PyTorch tensor residing on CPU shares the same storage as numpy array na

import torch
a = torch.ones((1,2))
print(a)
na = a.numpy()
na[0][0]=10
print(na)
print(a)

Output:

tensor([[1., 1.]])
[[10.  1.]]
tensor([[10.,  1.]])

Example: Eliminate effect of shared storage, copy numpy array first

To avoid the effect of shared storage we need to copy() the numpy array na to a new numpy array nac. Numpy copy() method creates the new separate storage.

import torch
a = torch.ones((1,2))
print(a)
na = a.numpy()
nac = na.copy()
nac[0][0]=10
?print(nac)
print(na)
print(a)

Output:

tensor([[1., 1.]])
[[10.  1.]]
[[1. 1.]]
tensor([[1., 1.]])

Now, just the nac numpy array will be altered with the line nac[0][0]=10, na and a will remain as is.

Example: CPU tensor with requires_grad=True

import torch
a = torch.ones((1,2), requires_grad=True)
print(a)
na = a.detach().numpy()
na[0][0]=10
print(na)
print(a)

Output:

tensor([[1., 1.]], requires_grad=True)
[[10.  1.]]
tensor([[10.,  1.]], requires_grad=True)

In here we call:

na = a.numpy() 

This would cause: RuntimeError: Can't call numpy() on Tensor that requires grad. Use tensor.detach().numpy() instead., because tensors that require_grad=True are recorded by PyTorch AD. Note that tensor.detach() is the new way for tensor.data.

This explains why we need to detach() them first before converting using numpy().

Example: CUDA tensor with requires_grad=False

a = torch.ones((1,2), device='cuda')
print(a)
na = a.to('cpu').numpy()
na[0][0]=10
print(na)
print(a)

Output:

tensor([[1., 1.]], device='cuda:0')
[[10.  1.]]
tensor([[1., 1.]], device='cuda:0')

?

Example: CUDA tensor with requires_grad=True

a = torch.ones((1,2), device='cuda', requires_grad=True)
print(a)
na = a.detach().to('cpu').numpy()
na[0][0]=10
?print(na)
print(a)

Output:

tensor([[1., 1.]], device='cuda:0', requires_grad=True)
[[10.  1.]]
tensor([[1., 1.]], device='cuda:0', requires_grad=True)

Without detach() method the error RuntimeError: Can't call numpy() on Tensor that requires grad. Use tensor.detach().numpy() instead. will be set.

Without .to('cpu') method TypeError: can't convert cuda:0 device type tensor to numpy. Use Tensor.cpu() to copy the tensor to host memory first. will be set.

You could use cpu() but instead of to('cpu') but I prefer the newer to('cpu').

I had the same issue. I installed gitx instead.

You can install gitx from here.

http://rowanj.github.io/gitx/

Download the package and install it. After that open the gitk from spotlight search, goto the top left corner. Click on GitX and enable the terminal usage.

Goto your repo and simply type:

$ gitx --all

It will open the Gui.

I used two methods and I found one method useful over other. Here is my answer:

My input data:

crkmod_mpp = ['M13','M18','M19','M24']
testmod_mpp = ['M13','M14','M15','M16','M17','M18','M19','M20','M21','M22','M23','M24']

Method1: np.setdiff1d I like this approach over other because it preserves the position

test= list(np.setdiff1d(testmod_mpp,crkmod_mpp))
print(test)
['M15', 'M16', 'M22', 'M23', 'M20', 'M14', 'M17', 'M21']

Method2: Though it gives same answer as in Method1 but disturbs the order

test = list(set(testmod_mpp).difference(set(crkmod_mpp)))
print(test)
['POA23', 'POA15', 'POA17', 'POA16', 'POA22', 'POA18', 'POA24', 'POA21']

Method1 np.setdiff1d meets my requirements perfectly. This answer for information.

The following are the 5 steps required:

1. declare the function pointer
2. Load the library
3. Get the procedure address
4. assign it to function pointer
5. call the function using function pointer

You can find the step by step VC++ IDE screen shot at http://www.softwareandfinance.com/Visual_CPP/DLLDynamicBinding.html

Here is the code snippet:

int main()
{
/***
__declspec(dllimport) bool GetWelcomeMessage(char *buf, int len); // used for static binding
 ***/
    typedef bool (*GW)(char *buf, int len);

    HMODULE hModule = LoadLibrary(TEXT("TestServer.DLL"));
    GW GetWelcomeMessage = (GW) GetProcAddress(hModule, "GetWelcomeMessage");

    char buf[128];
    if(GetWelcomeMessage(buf, 128) == true)
        std::cout << buf;
        return 0;
}

Your CA file must have been in a binary X.509 format instead of Base64 encoding; it needs to be a regular DER or PEM in order for it to be added successfully to the list of trusted CAs on your server.

To proceed, do place your CA file inside your /usr/share/pki/ca-trust-source/anchors/ directory, then run the command line below (you might need sudo privileges based on your settings);

# CentOS 7, Red Hat 7, Oracle Linux 7
update-ca-trust

Please note that all trust settings available in the /usr/share/pki/ca-trust-source/anchors/ directory are interpreted with a lower priority compared to the ones placed under the /etc/pki/ca-trust/source/anchors/ directory which may be in the extended BEGIN TRUSTED file format.

For Ubuntu and Debian systems, /usr/local/share/ca-certificates/ is the preferred directory for that purpose.

As such, you need to place your CA file within the /usr/local/share/ca-certificates/ directory, then update the of trusted CAs by running, with sudo privileges where required, the command line below;

update-ca-certificates

I'm not sure of the question, so here are two answers :

If you want to move your repository :

Simply copy the whole repository (with its .git directory).

There is no absolute path in the .git structure and nothing preventing it to be moved so you have nothing to do after the move. All the links to github (see in .git/config) will work as before.

If you want to move files inside the repository :

Simply move the files. Then add the changes listed in git status. The next commit will do the necessary. You'll be happy to learn that no file will be duplicated : moving a file in git is almost costless.

Update Nov. 2015: As per Hans Z. below - this is now indeed defined as part of RFC 7662.

Original Answer: The OAuth 2.0 spec (RFC 6749) doesn't clearly define the interaction between a Resource Server (RS) and Authorization Server (AS) for access token (AT) validation. It really depends on the AS's token format/strategy - some tokens are self-contained (like JSON Web Tokens) while others may be similar to a session cookie in that they just reference information held server side back at the AS.

There has been some discussion in the OAuth Working Group about creating a standard way for an RS to communicate with the AS for AT validation. My company (Ping Identity) has come up with one such approach for our commercial OAuth AS (PingFederate): https://support.pingidentity.com/s/document-item?bundleId=pingfederate-93&topicId=lzn1564003025072.html#lzn1564003025072__section_N10578_N1002A_N10001. It uses REST based interaction for this that is very complementary to OAuth 2.0.

Pillow is released with installation wheels on Windows:

We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included

https://pillow.readthedocs.io/en/3.3.x/installation.html#basic-installation

Update: Python 3.6 is now supported by Pillow. Install with pip install pillow and check https://pillow.readthedocs.io/en/latest/installation.html for more information.

However, Python 3.6 is still in alpha and not officially supported yet, although the tests do all pass for the nightly Python builds (currently 3.6a4).

Failing that, downgrade to Python 3.5 or wait until 3.6 is supported by Pillow, probably closer to the 3.6's official release.

In Kotlin:

 ivBall.setOnClickListener(View.OnClickListener {

            //Animate using XML
            // val rotateAnimation = AnimationUtils.loadAnimation(activity, R.anim.rotate_indefinitely)

            //OR using Code
            val rotateAnimation = RotateAnimation(
                    0f, 359f,
                    Animation.RELATIVE_TO_SELF, 0.5f,
                    Animation.RELATIVE_TO_SELF, 0.5f

            )
            rotateAnimation.duration = 300
            rotateAnimation.repeatCount = 2

            //Either way you can add Listener like this
            rotateAnimation.setAnimationListener(object : Animation.AnimationListener {

                override fun onAnimationStart(animation: Animation?) {
                }

                override fun onAnimationRepeat(animation: Animation?) {
                }

                }
            })

            ivBall.startAnimation(rotateAnimation)
        })

On Windows, Chrome might be installed in your AppData folder:

If the information you want is on the page you are directed to immediately after login...

Lets call your ck variable payload instead, like in the python-requests docs:

payload = {'inUserName': 'USERNAME/EMAIL', 'inUserPass': 'PASSWORD'}

requests.post(url, data=payload)

Otherwise...

See https://stackoverflow.com/a/17633072/111362 below.

I guess you have your css code in a database & you want to render a php file as a CSS. If that is the case...

   <!- head elements (Meta, title, etc) -->

   <!-- Link your php/css file -->
   <link rel="stylesheet" href="style.php" media="screen">

Then, within style.php file:

<?php
/*** set the content type header ***/
/*** Without this header, it wont work ***/
header("Content-type: text/css");


$font_family = 'Arial, Helvetica, sans-serif';
$font_size = '0.7em';

Calculate square root with arbitrary precision in Python

#!/usr/bin/env python
import decimal

def sqrt(n):
    assert n > 0
    with decimal.localcontext() as ctx:
        ctx.prec += 2 # increase precision to minimize round off error
        x, prior = decimal.Decimal(n), None
        while x != prior: 
            prior = x
            x = (x + n/x) / 2 # quadratic convergence 
    return +x # round in a global context


decimal.getcontext().prec = 80 # desirable precision
r = sqrt(12345)
print r
print r == decimal.Decimal(12345).sqrt()

Output:

111.10805551354051124500443874307524148991137745969772997648567316178259031751676

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

Indeed ADD go /usr/local/ will add content of go folder and not the folder itself, you can use Thomasleveil solution or if that did not work for some reason you can change WORKDIR to /usr/local/ then add your directory to it like:

WORKDIR /usr/local/
COPY go go/

or

WORKDIR /usr/local/go
COPY go ./

But if you want to add multiple folders, it will be annoying to add them like that, the only solution for now as I see it from my current issue is using COPY . . and exclude all unwanted directories and files in .dockerignore, let's say I got folders and files:

- src 
- tmp 
- dist 
- assets 
- go 
- justforfun 
- node_modules 
- scripts 
- .dockerignore 
- Dockerfile 
- headache.lock 
- package.json 

and I want to add src assets package.json justforfun go so:

in Dockerfile:

FROM galaxy:latest

WORKDIR /usr/local/
COPY . .

in .dockerignore file:

node_modules
headache.lock
tmp
dist

Or for more fun (or you like to confuse more people make them suffer as well :P) can be:

*
!src 
!assets 
!go 
!justforfun 
!scripts 
!package.json 

In this way you ignore everything, but excluding what you want to be copied or added only from "ignore list".

It is a late answer but adding more ways to do the same covering even more cases.

Try:

move "C:\files\*.txt" "C:\txt"

I suggest the save actions plugin. It also supports optimize imports and rearrange code.

Works well in combination with the eclipse formatter plugin.

Search and activate the plugin:

Configure it:

Edit: it seems like it the recent version of Intellij the save action plugin is triggered by the automatic Intellij save. This can be quite annoying when it hits while still editing.

This github issue of the plugin gives a hint to some possible solutions:

https://github.com/dubreuia/intellij-plugin-save-actions/issues/63

I actually tried to assign reformat to Ctrl+S and it worked fine - saving is done automatically now.

XMLBeans works great if you have a schema for your XML. It creates Java objects for the schema and creates easy to use parse methods.

Assuming you're looking for a quick tactical fix, what you need to do is make sure the cell image is initialized and also that the cell's row is still visible, e.g:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    MyCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];

    cell.poster.image = nil; // or cell.poster.image = [UIImage imageNamed:@"placeholder.png"];

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://myurl.com/%@.jpg", self.myJson[indexPath.row][@"movieId"]]];

    NSURLSessionTask *task = [[NSURLSession sharedSession] dataTaskWithURL:url completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        if (data) {
            UIImage *image = [UIImage imageWithData:data];
            if (image) {
                dispatch_async(dispatch_get_main_queue(), ^{
                    MyCell *updateCell = (id)[tableView cellForRowAtIndexPath:indexPath];
                    if (updateCell)
                        updateCell.poster.image = image;
                });
            }
        }
    }];
    [task resume];

    return cell;
}

The above code addresses a few problems stemming from the fact that the cell is reused:

1. You're not initializing the cell image before initiating the background request (meaning that the last image for the dequeued cell will still be visible while the new image is downloading). Make sure to nil the image property of any image views or else you'll see the flickering of images.

2. A more subtle issue is that on a really slow network, your asynchronous request might not finish before the cell scrolls off the screen. You can use the UITableView method cellForRowAtIndexPath: (not to be confused with the similarly named UITableViewDataSource method tableView:cellForRowAtIndexPath:) to see if the cell for that row is still visible. This method will return nil if the cell is not visible.

   The issue is that the cell has scrolled off by the time your async method has completed, and, worse, the cell has been reused for another row of the table. By checking to see if the row is still visible, you'll ensure that you don't accidentally update the image with the image for a row that has since scrolled off the screen.

3. Somewhat unrelated to the question at hand, I still felt compelled to update this to leverage modern conventions and API, notably:

   • Use NSURLSession rather than dispatching -[NSData contentsOfURL:] to a background queue;

   • Use dequeueReusableCellWithIdentifier:forIndexPath: rather than dequeueReusableCellWithIdentifier: (but make sure to use cell prototype or register class or NIB for that identifier); and

   • I used a class name that conforms to Cocoa naming conventions (i.e. start with the uppercase letter).

Even with these corrections, there are issues:

1. The above code is not caching the downloaded images. That means that if you scroll an image off screen and back on screen, the app may try to retrieve the image again. Perhaps you'll be lucky enough that your server response headers will permit the fairly transparent caching offered by NSURLSession and NSURLCache, but if not, you'll be making unnecessary server requests and offering a much slower UX.

2. We're not canceling requests for cells that scroll off screen. Thus, if you rapidly scroll to the 100th row, the image for that row could be backlogged behind requests for the previous 99 rows that aren't even visible anymore. You always want to make sure you prioritize requests for visible cells for the best UX.

The simplest fix that addresses these issues is to use a UIImageView category, such as is provided with SDWebImage or AFNetworking. If you want, you can write your own code to deal with the above issues, but it's a lot of work, and the above UIImageView categories have already done this for you.

In mvc 4 Could be rendered with Underscore(" _ ")

Razor:

@Html.ActionLink("Vote", "#", new { id = item.FileId, }, new { @class = "votes", data_fid = item.FileId, data_jid = item.JudgeID, })

Rendered Html

<a class="votes" data-fid="18587" data-jid="9" href="/Home/%23/18587">Vote</a>

Here's the method I use (for similar things, not just title):

<?
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<head>
<title><!--TITLE--></title>
</head>

<body>
<?
$pageTitle = 'Title of Page'; // Call this in your pages' files to define the page title
?>
</body>
</html>
<?
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer

// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
?>

PHP usually works be executing any bits of code and printing all output directly to the browser. If you say "echo 'Some text here.';", that string will get sent the browser and is emptied from memory.

What output buffering does is say "Print all output to a buffer. Hold onto it. Don't send ANYTHING to the browser until I tell you to."

So what this does is it buffers all your pages' HTML into the buffer, then at the very end, after the tag, it uses ob_get_contents () to get the contents of the buffer (which is usually all your page's HTML source code which would have been sent the browser already) and puts that into a string.

ob_end_clean () empties the buffer and frees some memory. We don't need the source code anymore because we just stored it in $pageContents.

Then, lastly, I do a simple find & replace on your page's source code ($pageContents) for any instances of '' and replace them to whatever the $pageTitle variable was set to. Of course, it will then replace <title><!--TITLE--></title> with Your Page's Title. After that, I echo the $pageContents, just like the browser would have.

It effectively holds onto output so you can manipulate it before sending it to the browser.

Hopefully my comments are clear enough. Look up ob_start () in the php manual ( http://php.net/ob_start ) if you want to know exactly how that works (and you should) :)

The answer your question: the correct way to refer to a different sheet is by appropriately qualifying each Range you use. Please read this explanation and its conclusion, which I guess will give essential information.

The error you are getting is likely due to the sought-for value Sheet2!D2 not being found in the searched range Sheet1!A1:A65536. This may stem from two cases:

1. The value is actually not present (pointed out by chris nielsen).

2. You are searching the wrong Range. If the ActiveSheet is Sheet1, then using Range("D2") without qualifying it will be searching for Sheet1!D2, and it will throw the same error even if the sought-for value is present in the correct Range. Code accounting for this (and items below) follows:

   Sub srch()
       Dim ws1 As Worksheet, ws2 As Worksheet
       Dim srchres As Variant
   
       Set ws1 = Worksheets("Sheet1")
       Set ws2 = Worksheets("Sheet2")
   
       On Error Resume Next
       srchres = Application.WorksheetFunction.VLookup(ws2.Range("D2"), ws1.Range("A1:C65536"), 1, False)
       On Error GoTo 0
       If (IsEmpty(srchres)) Then
         ws2.Range("E2").Formula = CVErr(xlErrNA) ' Use whatever you want
       Else
         ws2.Range("E2").Value = srchres
       End If
   End Sub
   

I will point out a few additional notable points:

1. Catching the error as done by chris nielsen is a good practice, probably mandatory if using Application.WorksheetFunction.VLookup (although it will not suitably handle case 2 above).

2. This catching is actually performed by the function VLOOKUP as entered in a cell (and, if the sought-for value is not found, the result of the error is presented as #N/A in the result). That is why the first soluton by L42 does not need any extra error handling (it is taken care by =VLOOKUP...).

3. Using =VLOOKUP... is fundamentally different from Application.WorksheetFunction.VLookup: the first leaves a formula, whose result may change if the cells referenced change; the second writes a fixed value.

4. Both solutions by L42 qualify Ranges suitably.

5. You are searching the first column of the range, and returning the value in that same column. Other functions are available for that (although yours works fine).

You can use the CssClass property of the hyperlink:

LiteralControl ltr = new LiteralControl();
        ltr.Text = "<style type=\"text/css\" rel=\"stylesheet\">" +
                    @".d
                    {
                        background-color:Red;
                    }
                    .d:hover
                    {
                        background-color:Yellow;
                    }
                    </style>
                    ";
        this.Page.Header.Controls.Add(ltr);
        this.HyperLink1.CssClass = "d";

You use ttk.Frame, bg option does not work for it. You should create style and apply it to the frame.

from tkinter import *
from tkinter.ttk import * 

root = Tk()

s = Style()
s.configure('My.TFrame', background='red')

mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()

UTF-8 encodes characters using 1 to 4 bytes per code point. As CMS pointed out in the accepted answer, JavaScript will store each character internally using 16 bits (2 bytes).

If you parse each character in the string via a loop and count the number of bytes used per code point, and then multiply the total count by 2, you should have JavaScript's memory usage in bytes for that UTF-8 encoded string. Perhaps something like this:

      getStringMemorySize = function( _string ) {
        "use strict";

        var codePoint
            , accum = 0
        ;

        for( var stringIndex = 0, endOfString = _string.length; stringIndex < endOfString; stringIndex++ ) {
            codePoint = _string.charCodeAt( stringIndex );

            if( codePoint < 0x100 ) {
                accum += 1;
                continue;
            }

            if( codePoint < 0x10000 ) {
                accum += 2;
                continue;
            }

            if( codePoint < 0x1000000 ) {
                accum += 3;
            } else {
                accum += 4;
            }
        }

        return accum * 2;
    }

Examples:

getStringMemorySize( 'I'    );     //  2
getStringMemorySize( '?'    );     //  4
getStringMemorySize( ''   );     //  8
getStringMemorySize( 'I?' );     // 14

I used dir /s /b /o:n /a:d, and it worked perfectly, just make sure you let the file finish writing, or you'll have an incomplete list.

use std::stringstream

unsigned int x;   
std::stringstream ss;
ss << std::hex << "fffefffe";
ss >> x;

the following example produces -65538 as its result:

#include <sstream>
#include <iostream>

int main() {
    unsigned int x;   
    std::stringstream ss;
    ss << std::hex << "fffefffe";
    ss >> x;
    // output it as a signed type
    std::cout << static_cast<int>(x) << std::endl;
}

In the new C++11 standard, there are a few new utility functions which you can make use of! specifically, there is a family of "string to number" functions (http://en.cppreference.com/w/cpp/string/basic_string/stol and http://en.cppreference.com/w/cpp/string/basic_string/stoul). These are essentially thin wrappers around C's string to number conversion functions, but know how to deal with a std::string

So, the simplest answer for newer code would probably look like this:

std::string s = "0xfffefffe";
unsigned int x = std::stoul(s, nullptr, 16);

NOTE: Below is my original answer, which as the edit says is not a complete answer. For a functional solution, stick the code above the line :-).

It appears that since lexical_cast<> is defined to have stream conversion semantics. Sadly, streams don't understand the "0x" notation. So both the boost::lexical_cast and my hand rolled one don't deal well with hex strings. The above solution which manually sets the input stream to hex will handle it just fine.

Boost has some stuff to do this as well, which has some nice error checking capabilities as well. You can use it like this:

try {
    unsigned int x = lexical_cast<int>("0x0badc0de");
} catch(bad_lexical_cast &) {
    // whatever you want to do...
}

If you don't feel like using boost, here's a light version of lexical cast which does no error checking:

template<typename T2, typename T1>
inline T2 lexical_cast(const T1 &in) {
    T2 out;
    std::stringstream ss;
    ss << in;
    ss >> out;
    return out;
}

which you can use like this:

// though this needs the 0x prefix so it knows it is hex
unsigned int x = lexical_cast<unsigned int>("0xdeadbeef"); 

SELECT D.DeptID, E.EmpName, E.Salary
FROM Employee E
INNER JOIN Department D ON D.DeptId = E.DeptId
WHERE E.Salary IN (SELECT MAX(Salary) FROM Employee);

You can use a lookahead:

/(?=\S)[^\\]/

Be very careful when cloning ArrayLists. Cloning in java is shallow. This means that it will only clone the Arraylist itself and not its members. So if you have an ArrayList X1 and clone it into X2 any change in X2 will also manifest in X1 and vice-versa. When you clone you will only generate a new ArrayList with pointers to the same elements in the original.

If you have a class with an object property, or if your property actually casts to an object, you can reshape the object by reassigning its properties, as in:

  MyClass varClass = new MyClass();
  varClass.propObjectProperty = new { Id = 1, Description = "test" };

  //if you need to treat the class as an object
  var varObjectProperty = ((dynamic)varClass).propObjectProperty;
  ((dynamic)varClass).propObjectProperty = new { Id = varObjectProperty.Id, Description = varObjectProperty.Description, NewDynamicProperty = "new dynamic property description" };

  //if your property is an object, instead
  var varObjectProperty = varClass.propObjectProperty;
  varClass.propObjectProperty = new { Id = ((dynamic)varObjectProperty).Id, Description = ((dynamic)varObjectProperty).Description, NewDynamicProperty = "new dynamic property description" };

With this approach, you basically rewrite the object property adding or removing properties as if you were first creating the object with the

new { ... }

syntax.

In your particular case, you're probably better off creating an actual object to which you assign properties like "dob" and "address" as if it were a person, and at the end of the process, transfer the properties to the actual "Person" object.

'hg forget' is just shorthand for 'hg remove -Af'. From the 'hg remove' help:

...and -Af can be used to remove files from the next revision without deleting them from the working directory.

Bottom line: 'remove' deletes the file from your working copy on disk (unless you uses -Af) and 'forget' doesn't.

Quoting the RFC 2616 Fielding

The DELETE method requests that the origin server delete the resource identified by the Request-URI.

So you need to pass the data in the URI

$.ajax({

    type: 'DELETE',
    success: callback || $.noop,

will also recognize urls such as google.com , http://www.google.bla , http://google.bla , www.google.bla but not google.bla

I believe it would be like this

takedata.match(/(\[.+\])/g);

the g at the end means global, so it doesn't stop at the first match.

If the types of the parameters are all the same (varchar2 for example), you can have a package like this which will do the following:

CREATE OR REPLACE PACKAGE testuser.test_pkg IS

   TYPE assoc_array_varchar2_t IS TABLE OF VARCHAR2(4000) INDEX BY BINARY_INTEGER;

   PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t);

END test_pkg;

CREATE OR REPLACE PACKAGE BODY testuser.test_pkg IS

   PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t) AS
   BEGIN
      FOR i IN p_parm.first .. p_parm.last
      LOOP
         dbms_output.put_line(p_parm(i));
      END LOOP;

   END;

END test_pkg;

Then, to call it you'd need to set up the array and pass it:

DECLARE
  l_array testuser.test_pkg.assoc_array_varchar2_t;
BEGIN
  l_array(0) := 'hello';
  l_array(1) := 'there';  

  testuser.test_pkg.your_proc(l_array);
END;
/

When you make the input, set it to be readonly.

<input type="text" name="datepicker" id="datepicker" readonly="readonly" />

An alternative approach is resample, which can handle duplicate dates in addition to missing dates. For example:

df.resample('D').mean()

resample is a deferred operation like groupby so you need to follow it with another operation. In this case mean works well, but you can also use many other pandas methods like max, sum, etc.

Here is the original data, but with an extra entry for '2013-09-03':

             val
date           
2013-09-02     2
2013-09-03    10
2013-09-03    20    <- duplicate date added to OP's data
2013-09-06     5
2013-09-07     1

And here are the results:

             val
date            
2013-09-02   2.0
2013-09-03  15.0    <- mean of original values for 2013-09-03
2013-09-04   NaN    <- NaN b/c date not present in orig
2013-09-05   NaN    <- NaN b/c date not present in orig
2013-09-06   5.0
2013-09-07   1.0

I left the missing dates as NaNs to make it clear how this works, but you can add fillna(0) to replace NaNs with zeroes as requested by the OP or alternatively use something like interpolate() to fill with non-zero values based on the neighboring rows.

For centOS, maybe can try following steps

cd /tmp
wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make
cp src/redis-cli /usr/local/bin/
chmod 755 /usr/local/bin/redis-cli

To change database owner:

ALTER AUTHORIZATION ON DATABASE::YourDatabaseName TO sa

As of SQL Server 2014 you can still use sp_changedbowner as well, even though Microsoft promised to remove it in the "future" version after SQL Server 2012. They removed it from SQL Server 2014 BOL though.

You can do like this: cat [directory_path]/**/*.[h,m] > test.txt

if you use {} to include the extension of the files you want to find, there is a sequencing problem.

I don't have a high enough reputation to comment on Gavin Simpson's answer, but I wanted to warn that there seems to be a difference in the default treatment of missing values between the standard syntax and the formula syntax for aggregate.

#Create some data with missing values 
a<-data.frame(day=rep(1,5),hour=c(1,2,3,3,4),val=c(1,NA,3,NA,5))
  day hour val
1   1    1   1
2   1    2  NA
3   1    3   3
4   1    3  NA
5   1    4   5

#Standard syntax
aggregate(a$val,by=list(day=a$day,hour=a$hour),mean,na.rm=T)
  day hour   x
1   1    1   1
2   1    2 NaN
3   1    3   3
4   1    4   5

#Formula syntax.  Note the index for hour 2 has been silently dropped.
aggregate(val ~ hour + day,data=a,mean,na.rm=T)
  hour day val
1    1   1   1
2    3   1   3
3    4   1   5

Use TextAreaFor

@Html.TextAreaFor(model => model.Description, new { @class = "whatever-class", @cols = 80, @rows = 10 })

or use style for multi-line class.

You could also write EditorTemplate for this.

I'm probably about where the OP was when this started, looking for something simple that would let me use git difftool with vimdiff to review changes to files in my repo starting from a specific commit. I wasn't too happy with answers I was finding, so I threw this git incremental reporter (gitincrep) script together and it's been useful to me:

#!/usr/bin/env bash

STARTWITH="${1:-}"
shift 1

DFILES=( "$@" )

RunDiff()
{
        GIT1=$1
        GIT2=$2
        shift 2

        if [ "$(git diff $GIT1 $GIT2 "$@")" ]
        then
                git log ${GIT1}..${GIT2}
                git difftool --tool=vimdiff $GIT1 $GIT2 "$@"
        fi
}

OLDVERS=""
RUNDIFF=""

for NEWVERS in $(git log --format=format:%h  --reverse)
do
        if [ "$RUNDIFF" ]
        then
                RunDiff $OLDVERS $NEWVERS "${DFILES[@]}"
        elif [ "$OLDVERS" ]
        then
                if [ "$NEWVERS" = "${STARTWITH:=${NEWVERS}}" ]
                then
                        RUNDIFF=true
                        RunDiff $OLDVERS $NEWVERS "${DFILES[@]}"
                fi
        fi
        OLDVERS=$NEWVERS
done

Called with no args, this will start from the beginning of the repo history, otherwise it will start with whatever abbreviated commit hash you provide and proceed to the present - you can ctrl-C at any time to exit. Any args after the first will limit the difference reports to include only the files listed among those args (which I think is what the OP wanted, and I'd recommend for all but tiny projects). If you're checking changes to specific files and want to start from the beginning, you'll need to provide an empty string for arg1. If you're not a vim user, you can replace vimdiff with your favorite diff tool.

Behavior is to output the commit comments when relevant changes are found and start offering vimdiff runs for each changed file (that's git difftool behavior, but it works here).

This approach is probably pretty naive, but looking through a lot of the solutions here and at a related post, many involved installing new tools on a system where I don't have admin access, with interfaces that had their own learning curve. The above script did what I wanted without dealing with any of that. I'll look into the many excellent suggestions here when I need something more sophisticated - but I think this is directly responsive to the OP.

I have seen the same error message after upgrading to git1.8.5.2:

Simply make a search for all msys-1.0.dll on your C:\ drive, and make the one used by Git comes first.

For instance, in my case I simply changed the order of:

C:\prgs\Gow\Gow-0.7.0\bin\msys-1.0.dll
C:\prgs\git\PortableGit-1.8.5.2-preview20131230\bin\msys-1.0.dll

By making the Git path C:\prgs\git\PortableGit-1.8.5.2-preview20131230\bin\ come first in my %PATH%, the error message disappeared.

No need to reboot or to even change the DOS session.
Once the %PATH% is updated in that DOS session, the git commands just work.

Note that carmbrester and Sixto Saez both report below (in the comments) having to reboot in order to fix the issue.
Note: First, also removing any msys-1.0.dll, like one in %LOCALAPPDATA%

The NSDictionary and NSMutableDictionary docs are probably your best bet. They even have some great examples on how to do various things, like...

...create an NSDictionary

NSArray *keys = [NSArray arrayWithObjects:@"key1", @"key2", nil];
NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", nil];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects 
                                                       forKeys:keys];

...iterate over it

for (id key in dictionary) {
    NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]);
}

...make it mutable

NSMutableDictionary *mutableDict = [dictionary mutableCopy];

Note: historic version before 2010: [[dictionary mutableCopy] autorelease]

...and alter it

[mutableDict setObject:@"value3" forKey:@"key3"];

...then store it to a file

[mutableDict writeToFile:@"path/to/file" atomically:YES];

...and read it back again

NSMutableDictionary *anotherDict = [NSMutableDictionary dictionaryWithContentsOfFile:@"path/to/file"];

...read a value

NSString *x = [anotherDict objectForKey:@"key1"];

...check if a key exists

if ( [anotherDict objectForKey:@"key999"] == nil ) NSLog(@"that key is not there");

...use scary futuristic syntax

From 2014 you can actually just type dict[@"key"] rather than [dict objectForKey:@"key"]

Just in case if you have a loop or a json string that need to insert in the database. Try to replace the string with a single quote . here is my solution. example if you have a string that contain's a single quote.

String mystring = "Sample's";
String myfinalstring = mystring.replace("'","''");

 String query = "INSERT INTO "+table name+" ("+field1+") values ('"+myfinalstring+"')";

this works for me in c# and java

Can you output that data in the cells as you are creating the table?

so your table would look like this:

<table>
  <thead>...</thead>
  <tbody>
    <tr><td data-row='1' data-column='1'>value</td>
      <td data-row='1' data-column='2'>value</td>
      <td data-row='1' data-column='3'>value</td></tr>

  <tbody>
</table>

then it would be a simple matter

$("td").click(function(event) {
   var row = $(this).attr("data-row");
   var col = $(this).attr("data-col");
}

You can also do something:

SELECT CAST(CAST(34512367.392 AS decimal(30,9)) AS NVARCHAR(100))

Output: 34512367.392000000

You have to right idea generating the url based off of the input value. The only issue is you are using window.location.href. Setting window.location.href changes the url of the current window. What you probably want to do is change the src attribute of an image.

<html>
<body>
<form>
  <input type="text" value="" id="imagename">
  <input type="button" onclick="var image = document.getElementById('the-image'); image.src='http://webpage.com/images/'+document.getElementById('imagename').value +'.png'" value="GO">
</form>
<img id="the-image">
</body>
</html>

Using Spark 2.0+, we can load multiple CSV files from different directories using df = spark.read.csv(['directory_1','directory_2','directory_3'.....], header=True). For more information, refer the documentation here

Instead of extrapolating off the ends, you could return the extents of the y_list. Most of the time your application is well behaved, and the Interpolate[x] will be in the x_list. The (presumably) linear affects of extrapolating off the ends may mislead you to believe that your data is well behaved.

• Returning a non-linear result (bounded by the contents of x_list and y_list) your program's behavior may alert you to an issue for values greatly outside x_list. (Linear behavior goes bananas when given non-linear inputs!)

• Returning the extents of the y_list for Interpolate[x] outside of x_list also means you know the range of your output value. If you extrapolate based on x much, much less than x_list[0] or x much, much greater than x_list[-1], your return result could be outside of the range of values you expected.

  def __getitem__(self, x):
      if x <= self.x_list[0]:
          return self.y_list[0]
      elif x >= self.x_list[-1]:
          return self.y_list[-1]
      else:
          i = bisect_left(self.x_list, x) - 1
          return self.y_list[i] + self.slopes[i] * (x - self.x_list[i])
  

JAXB is an ideal solution. But you do not necessarily need xsd and xjc for that. More often than not you don't have an xsd but you know what your xml is. Simply analyze your xml, e.g.,

<customer id="100">
    <age>29</age>
    <name>mkyong</name>
</customer>

Create necessary model class(es):

@XmlRootElement
public class Customer {

    String name;
    int age;
    int id;

    public String getName() {
        return name;
    }

    @XmlElement
    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    @XmlElement
    public void setAge(int age) {
        this.age = age;
    }

    public int getId() {
        return id;
    }

    @XmlAttribute
    public void setId(int id) {
        this.id = id;
    }

}

Try to unmarshal:

JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Customer customer = (Customer) jaxbUnmarshaller.unmarshal(new File("C:\\file.xml"));

Inline styling does not support pseudos or at-rules (e.g., @media). Recommendations range from reimplement CSS features in JavaScript for CSS states like :hover via onMouseEnter and onMouseLeave to using more elements to reproduce pseudo-elements like :after and :before to just use an external stylesheet.

Personally dislike all of those solutions. Reimplementing CSS features via JavaScript does not scale well -- neither does adding superfluous markup.

Imagine a large team wherein each developer is recreating CSS features like :hover. Each developer will do it differently, as teams grow in size, if it can be done, it will be done. Fact is with JavaScript there are about n ways to reimplement CSS features, and over time you can bet on every one of those ways being implemented with the end result being spaghetti code.

So what to do? Use CSS. Granted you asked about inline styling going to assume you're likely in the CSS-in-JS camp (me too!). Have found colocating HTML and CSS to be as valuable as colocating JS and HTML, lots of folks just don't realise it yet (JS-HTML colocation had lots of resistance too at first).

Made a solution in this space called Style It that simply lets your write plaintext CSS in your React components. No need to waste cycles reinventing CSS in JS. Right tool for the right job, here is an example using :after:

INSERTED and DELETED are virtual tables. They need to be used in a FROM clause.

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    IF EXISTS (SELECT foo
               FROM database2.dbo.table2
               WHERE id IN (SELECT deleted.id FROM deleted)
               AND bar = 4)

It helped my case to install the right curl version

sudo apt-get install php5-curl

To read a file — one byte at a time (ignoring the buffering) — you could use the two-argument iter(callable, sentinel) built-in function:

with open(filename, 'rb') as file:
    for byte in iter(lambda: file.read(1), b''):
        # Do stuff with byte

It calls file.read(1) until it returns nothing b'' (empty bytestring). The memory doesn't grow unlimited for large files. You could pass buffering=0 to open(), to disable the buffering — it guarantees that only one byte is read per iteration (slow).

with-statement closes the file automatically — including the case when the code underneath raises an exception.

Despite the presence of internal buffering by default, it is still inefficient to process one byte at a time. For example, here's the blackhole.py utility that eats everything it is given:

#!/usr/bin/env python3
"""Discard all input. `cat > /dev/null` analog."""
import sys
from functools import partial
from collections import deque

chunksize = int(sys.argv[1]) if len(sys.argv) > 1 else (1 << 15)
deque(iter(partial(sys.stdin.detach().read, chunksize), b''), maxlen=0)

Example:

$ dd if=/dev/zero bs=1M count=1000 | python3 blackhole.py

It processes ~1.5 GB/s when chunksize == 32768 on my machine and only ~7.5 MB/s when chunksize == 1. That is, it is 200 times slower to read one byte at a time. Take it into account if you can rewrite your processing to use more than one byte at a time and if you need performance.

mmap allows you to treat a file as a bytearray and a file object simultaneously. It can serve as an alternative to loading the whole file in memory if you need access both interfaces. In particular, you can iterate one byte at a time over a memory-mapped file just using a plain for-loop:

from mmap import ACCESS_READ, mmap

with open(filename, 'rb', 0) as f, mmap(f.fileno(), 0, access=ACCESS_READ) as s:
    for byte in s: # length is equal to the current file size
        # Do stuff with byte

mmap supports the slice notation. For example, mm[i:i+len] returns len bytes from the file starting at position i. The context manager protocol is not supported before Python 3.2; you need to call mm.close() explicitly in this case. Iterating over each byte using mmap consumes more memory than file.read(1), but mmap is an order of magnitude faster.

You can also try this:

EditText searchTo = (EditText)findViewById(R.id.medittext);
searchTo.addTextChangedListener(new TextWatcher() {
    @Override
    public void afterTextChanged(Editable s) {
        // TODO Auto-generated method stub
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        doSomething();
    } 
});

Run this command in project root directory.

1>. List of iPhone devices for found the connected Real Devices and Simulator. same as like adb devices command for android.

xcrun instruments -s devices

2>. Select device using this command which you want to run your app

Using Device Name

react-native run-ios --device "Kool's iPhone"

Using UDID

react-native run-ios --device --udid 0412e2c2******51699

wait and watch to run your app in specific devices - K00L ;)

<script type="text/javascript">
  var timeout = setTimeout("location.reload(true);",600000);
  function resetTimeout() {
    clearTimeout(timeout);
    timeout = setTimeout("location.reload(true);",600000);
  }
</script>

Above will refresh the page every 10 minutes unless resetTimeout() is called. For example:

<a href="javascript:;" onclick="resetTimeout();">clicky</a>

You can simply use CSS transitions, see this fiddle

.on {
color:#fff;
transition:all 1s;
}

.off{
color:#000;
transition:all 1s;
}

This simple way to do v-on:click="firstFunction(); secondFunction();"

    boolean x;
    for (x = false, 
        map.put("One", new Integer(1)), 
        map.put("Two", new Integer(2)),      
        map.put("Three", new Integer(3)); x;);

Ignoring the declaration of x (which is necessary to avoid an "unreachable statement" diagnostic), technically it's only one statement.

The function argument to setTimeout is closing over the loop variable. The loop finishes before the first timeout and displays the current value of i, which is 3.

Because JavaScript variables only have function scope, the solution is to pass the loop variable to a function that sets the timeout. You can declare and call such a function like this:

for (var i = 1; i <= 2; i++) {
    (function (x) {
        setTimeout(function () { alert(x); }, 100);
    })(i);
}

Open the Console view, locate the console for your running app and hit the Big Red Button.

Alternatively if you open the Debug perspective you will see all running apps in (by default) the top left. You can select the one that's causing you grief and once again hit the Big Red Button.

Why are people using list slicing (slow because it copies to a new list), importing a library function, or trying to rotate an array for this?

Use a normal for-loop with range(start, stop, step) (where start and step are optional arguments).

For example, looping through an array starting at index 1:

for i in range(1, len(arr)):
    print(arr[i])

This isn't appropriate in all situations but you can conditionally return false inside the component itself if a certain criteria is or isn't met.

It doesn't unmount the component, but it removes all rendered content. This would only be bad, in my mind, if you have event listeners in the component that should be removed when the component is no longer needed.

import React, { Component } from 'react';

export default class MyComponent extends Component {
    constructor(props) {
        super(props);

        this.state = {
            hideComponent: false
        }
    }

    closeThis = () => {
        this.setState(prevState => ({
            hideComponent: !prevState.hideComponent
        })
    });

    render() {
        if (this.state.hideComponent === true) {return false;}

        return (
            <div className={`content`} onClick={() => this.closeThis}>
                YOUR CODE HERE
            </div>
        );
    }
}

Here is a way to do it without adding an ID to the form elements.

<form method="post">
    ...
    <select name="List">
        <option value="1">Test1</option>
        <option value="2">Test2</option>
    </select>
    <select name="List">
        <option value="3">Test3</option>
        <option value="4">Test4</option>
    </select>
    ...
</form>

public ActionResult OrderProcessor()
{
    string[] ids = Request.Form.GetValues("List");
}

Then ids will contain all the selected option values from the select lists. Also, you could go down the Model Binder route like so:

public class OrderModel
{
    public string[] List { get; set; }
}

public ActionResult OrderProcessor(OrderModel model)
{
    string[] ids = model.List;
}

Hope this helps.

You can use the Membership Operator isCase() which is another groovy way:

assert Date.isCase(new Date())

As mentioned in the comments, some labels in y_test don't appear in y_pred. Specifically in this case, label '2' is never predicted:

>>> set(y_test) - set(y_pred)
{2}

This means that there is no F-score to calculate for this label, and thus the F-score for this case is considered to be 0.0. Since you requested an average of the score, you must take into account that a score of 0 was included in the calculation, and this is why scikit-learn is showing you that warning.

This brings me to you not seeing the error a second time. As I mentioned, this is a warning, which is treated differently from an error in python. The default behavior in most environments is to show a specific warning only once. This behavior can be changed:

import warnings
warnings.filterwarnings('always')  # "error", "ignore", "always", "default", "module" or "once"

If you set this before importing the other modules, you will see the warning every time you run the code.

There is no way to avoid seeing this warning the first time, aside for setting warnings.filterwarnings('ignore'). What you can do, is decide that you are not interested in the scores of labels that were not predicted, and then explicitly specify the labels you are interested in (which are labels that were predicted at least once):

>>> metrics.f1_score(y_test, y_pred, average='weighted', labels=np.unique(y_pred))
0.91076923076923078

The warning is not shown in this case.

You don't need jQuery to create a Script DOM Element. It can be done with vanilla ES6 like so:

const script = "console.log('Did it work?')"
new Promise((resolve, reject) => {
  (function(i,s,o,g,r,a,m){
      a=s.createElement(o),m=s.getElementsByTagName(o)[0];
      a.innerText=g;
      a.onload=r;m.parentNode.insertBefore(a,m)}
  )(window,document,'script',script, resolve())
}).then(() => console.log('Sure did!'))

It doesn't need to be wrapped in a Promise, but doing so allows you to resolve the promise when the script loads, helping prevent race conditions for long-running scripts.

When creating a New Project, under the language of your choice, select Web and then change to .NET Framework 3.5 and you will get the option of creating an ASP.NET WEB Service Application.

You should have access to the POST dictionary on the request object.

solved this problem in the /app/app.module.ts file

import your component and declare it

import { MyComponent } from './home-about-me/my.component';

@NgModule({
  declarations: [
    MyComponent,
  ]

remember password needs to be set further even after restarting mysql as below

SET PASSWORD = PASSWORD('root');

    try 
    {  
      String datestr="06/27/2007";
      DateFormat formatter; 
      Date date; 
      formatter = new SimpleDateFormat("MM/dd/yyyy");
      date = (Date)formatter.parse(datestr);  
    } 
    catch (Exception e)
    {}

month is MM, minutes is mm..

You could try

cat FILE | awk '{print NF}'

I know this is a very old question but it may be that you need to set the request headers. This solved it for me.

For example 'user-agent', 'accept' etc. here is an example with user-agent:

url = 'your-url-here'
headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36'}
r = requests.get(url, headers=headers)

nginx "fails fast" when the client informs it that it's going to send a body larger than the client_max_body_size by sending a 413 response and closing the connection.

Most clients don't read responses until the entire request body is sent. Because nginx closes the connection, the client sends data to the closed socket, causing a TCP RST.

If your HTTP client supports it, the best way to handle this is to send an Expect: 100-Continue header. Nginx supports this correctly as of 1.2.7, and will reply with a 413 Request Entity Too Large response rather than 100 Continue if Content-Length exceeds the maximum body size.

one is Big "O"

one is Big Theta

http://en.wikipedia.org/wiki/Big_O_notation

Big O means your algorithm will execute in no more steps than in given expression(n^2)

Big Omega means your algorithm will execute in no fewer steps than in the given expression(n^2)

When both condition are true for the same expression, you can use the big theta notation....

$request->fullUrl() will also work if you are injecting Illumitate\Http\Request.

Simple prevent the default behavior of click, dblclick or touchend events will disable the zoom functionality.

If you have already a callback on one of this events just call a event.preventDefault().

Rebase: You Ain't Gonna Need It:

A simpler way for most frequent scenario.

In most cases:

Actually if all you want is just simply combine several recent commits into one but do not need drop, reword and other rebase work.

you can simply do:

git reset --soft "HEAD~n"

• Assuming ~n is number of commits to softly un-commit (i.e. ~1, ~2,...)

Then, use following command to modify the commit message.

git commit --amend

which is pretty much the same as a long range of squash and one pick.

And it works for n commits but not just two commits as above answer prompted.

Shorthand way to do present the alert in Objective-C:

[[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:alertController animated:YES completion:nil];

Where alertController is your UIAlertController object.

NOTE: You'll also need to make sure your helper class extends UIViewController

I like the answer of Patrick Cuff. What I like to add is the distinction between a test level and a test type which was for me an eye opener.

test levels

Test level is easy to explain using V-model, an example: Each test level has its corresponding development level. It has a typical time characteristic, they're executed at certain phase in the development life cycle.

1. component/unit testing => verifying detailed design
2. component/unit integration testing => verifying global design
3. system testing => verifying system requirements
4. system integration testing => verifying system requirements
5. acceptance testing => validating user requirements

test types

A test type is a characteristics, it focuses on a specific test objective. Test types emphasize your quality aspects, also known as technical or non-functional aspects. Test types can be executed at any test level. I like to use as test types the quality characteristics mentioned in ISO/IEC 25010:2011.

1. functional testing
2. reliability testing
3. performance testing
4. operability testing
5. security testing
6. compatibility testing
7. maintainability testing
8. transferability testing

To make it complete. There's also something called regression testing. This an extra classification next to test level and test type. A regression test is a test you want to repeat because it touches something critical in your product. It's in fact a subset of tests you defined for each test level. If a there's a small bug fix in your product, one doesn't always have the time to repeat all tests. Regression testing is an answer to that.

origin/master is the remote master branch

Usually after doing a git fetch origin to bring all the changes from the server, you would do a git rebase origin/master, to rebase your changes and move the branch to the latest index. Here, origin/master is referring to the remote branch, because you are basically telling GIT to rebase the origin/master branch onto the current branch.

You would use origin master when pushing, for example. git push origin master is simply telling GIT to push to the remote repository the local master branch.

Fast answer:

git log $(git merge-base master b2)..HEAD

Let's say:

1. That you have a master branch

2. Do a few commits

3. You created a branch named b2

4. Do git log -n1; the commit Id is the merge base between b2 and master

5. Do a few commits in b2

6. git log will show your log history of b2 and master

7. Use commit range, if you aren't familiar with the concept, I invite you to google it or stack overflow-it,

   For your actual context, you can do for example

   git log commitID_FOO..comitID_BAR
   

   The ".." is the range operator for the log command.

   That mean, in a simple form, give me all logs more recent than commitID_FOO...

8. Look at point #4, the merge base

   So: git log COMMITID_mergeBASE..HEAD will show you the difference

9. Git can retrieve the merge base for you like this

   git merge-base b2 master
   

10. Finally you can do:

    git log $(git merge-base master b2)..HEAD
    

Use method

Enum.GetName(Type MyEnumType,  object enumvariable)  

as in (Assume Shipper is a defined Enum)

Shipper x = Shipper.FederalExpress;
string s = Enum.GetName(typeof(Shipper), x);

There are a bunch of other static methods on the Enum class worth investigating too...

In Fujimoto Youichi's example test01 is a container, whereas test02 is an image.

Before doing docker run you can remove the original container and then assign the container the same name again:

$ docker stop container01
$ docker commit container01 image01
$ docker rm container01
$ docker run -d -P --name container01 image01

(Using -P to expose ports to random ports rather than manually assigning).

Another way would be to import VERSION constant from @angular/core and then dumping to console with:

console.log(VERSION.full); //5.2.11

Works in:

• Angular 8 See docs
• Angular 7 See docs
• Angular 6 See docs.
• Angular 5 See docs
• Angular 4 See docs

Not sure about Angular 2 and 3. (if someone could test that; pages are not available)

For AngularJS 1.x use angular.version:

console.log(angular.version); //1.7.4

When you need to accept a function as argument which takes no arguments and returns no result (void), in my opinion it is still best to have something like

  public interface Thunk { void apply(); }

somewhere in your code. In my functional programming courses the word 'thunk' was used to describe such functions. Why it isn't in java.util.function is beyond my comprehension.

In other cases I find that even when java.util.function does have something that matches the signature I want - it still doesn't always feel right when the naming of the interface doesn't match the use of the function in my code. I guess it's a similar point that is made elsewhere here regarding 'Runnable' - which is a term associated with the Thread class - so while it may have he signature I need, it is still likely to confuse the reader.

You probably already know about $(document).ready(...). What you need is a preloading mechanism; something that fetches data (text or images or whatever) before showing it off. This can make a site feel much more professional.

Take a look at jQuery.Preload (there are others). jQuery.Preload has several ways of triggering preloading, and also provides callback functionality (when the image is preloaded, then show it). I have used it heavily, and it works great.

Here's how easy it is to get started with jQuery.Preload:

$(function() {
  // First get the preload fetches under way
  $.preload(["images/button-background.png", "images/button-highlight.png"]);
  // Then do anything else that you would normally do here
  doSomeStuff();
});

<script>
    setTimeout(function(){
        window.location.href = 'form2.html';
    }, 5000);
</script>

And for home page add only '/'

<script>
    setTimeout(function(){
        window.location.href = '/';
    }, 5000);
</script>

SELECT sum(num) WHERE num = 1;

As of Spark 2.0.0, you can do the following.

Case Class

Let's define a Person case class:

scala> case class Person(id: Int, name: String)
defined class Person

Import spark SparkSession implicit Encoders:

scala> import spark.implicits._
import spark.implicits._

And use SparkSession to create an empty Dataset[Person]:

scala> spark.emptyDataset[Person]
res0: org.apache.spark.sql.Dataset[Person] = [id: int, name: string]

Schema DSL

You could also use a Schema "DSL" (see Support functions for DataFrames in org.apache.spark.sql.ColumnName).

scala> val id = $"id".int
id: org.apache.spark.sql.types.StructField = StructField(id,IntegerType,true)

scala> val name = $"name".string
name: org.apache.spark.sql.types.StructField = StructField(name,StringType,true)

scala> import org.apache.spark.sql.types.StructType
import org.apache.spark.sql.types.StructType

scala> val mySchema = StructType(id :: name :: Nil)
mySchema: org.apache.spark.sql.types.StructType = StructType(StructField(id,IntegerType,true), StructField(name,StringType,true))

scala> import org.apache.spark.sql.Row
import org.apache.spark.sql.Row

scala> val emptyDF = spark.createDataFrame(sc.emptyRDD[Row], mySchema)
emptyDF: org.apache.spark.sql.DataFrame = [id: int, name: string]

scala> emptyDF.printSchema
root
 |-- id: integer (nullable = true)
 |-- name: string (nullable = true)

We can set layout gravity on any view like below way-

myView = findViewById(R.id.myView);
myView.setGravity(Gravity.CENTER_VERTICAL|Gravity.RIGHT);
 or
myView.setGravity(Gravity.BOTTOM);

This is equilent to below xml code

<...
 android:gravity="center_vertical|right"
 ...
 .../>

You may catch multiple exceptions in single catch block.

try{
  // somecode throwing multiple exceptions;
} catch (Exception1 | Exception2 | Exception3 exception){
  // handle exception.
} 

With Guava 15 you can also simply use:

Set s = Sets.newConcurrentHashSet();

another Swift 3 Example. The provided solution did not work for me.

private func playVideo(from file:String) {
    let file = file.components(separatedBy: ".")

    guard let path = Bundle.main.path(forResource: file[0], ofType:file[1]) else {
        debugPrint( "\(file.joined(separator: ".")) not found")
        return
    }
    let player = AVPlayer(url: URL(fileURLWithPath: path))

    let playerLayer = AVPlayerLayer(player: player)
    playerLayer.frame = self.view.bounds
    self.view.layer.addSublayer(playerLayer)

First, close all instances of Google Chrome. There should be no instances of chrome.exe running in the Windows Task Manager. Then

• Go to %LOCALAPPDATA%\Google\Chrome\User Data\Default\.
• Open the file "Preferences" in a text editor like Notepad.
• First, resave the file to something like "Preference - Old" without any extension (i.e. no .txt). This will serve as a backup, should something go wrong.
• Look for a section called "browser." Inside that section, you should find a subsection called window_placement. Under window_placement you will see things like "bottom", "left", "right", etc. with numbers after them.

You will need to play around with these numbers to get your desired window size and placement. When finished, save this file with the name "Preferences" again with no extension. This will overwrite the existing Preferences file. Open Chrome and see how you did. If you're not satisfied with the size and placement, close Chrome and change the numbers in the Preferences file until you get what you want.

update of @Vladimir Tolstikov's answer

Create a Child Component that use ngOnChanges.

ChildComponent.ts::

import { Component, OnChanges, Input } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'child',
  templateUrl: 'child.component.html',
})

export class ChildComponent implements OnChanges {
  @Input() child_id;

  constructor(private route: ActivatedRoute) { }

  ngOnChanges() {
    // create header using child_id
    console.log(this.child_id);
  }
}

now use it in MasterComponent's template and pass data to ChildComponent like:

<child [child_id]="child_id"></child>

An even easier solution, just iterate through all popovers and hide if not this.

$(document).on('click', '.popup-marker', function() {
    $(this).popover('toggle')
})

$(document).bind('click touchstart', function(e) {
    var target = $(e.target)[0];
    $('.popup-marker').each(function () {
        // hide any open popovers except for the one we've clicked
        if (!$(this).is(target)) {
            $(this).popover('hide');
        }
    });
});

Replace [ with nothing, then ] with nothing.

Personally, I'd code it as tinyint and:

• Either: change it to text on the client, check constraint between 1 and 4
• Or: use a lookup table with a foreign key

Reasons:

• It will take on average 8 bytes to store text, 1 byte for tinyint. Over millions of rows, this will make a difference.

• What about collation? Is "Daily" the same as "DAILY"? It takes resources to do this kind of comparison.

• Finally, what if you want to add "Biweekly" or "Hourly"? This requires a schema change when you could just add new rows to a lookup table.

Imagine you pass a mutable string to a function but don't expect it to be changed. Then what if the function changes that string? In C++, for instance, you could simply do call-by-value (difference between std::string and std::string& parameter), but in C# it's all about references so if you passed mutable strings around every function could change it and trigger unexpected side effects.

This is just one of various reasons. Performance is another one (interned strings, for example).

Why are you not using this?

int[] array = { 12, 56, 89, 65, 61, 36, 45, 23 };
int max = array.Max();
int min = array.Min();

Below steps helped me fix this.

• upgrade pip version
• remove the created environment by using command rm -rf env-name
• create environment using command python3 -m venv env-aide
• now install the package and check

If I remember correctly from my own use of bootstrap, the .spanN classes are floated, which automatically makes them behave as display: block. To make display: table-cell work, you need to remove the float.

In case of Include Program will not terminate and display warning on browser,On the other hand Require program will terminate and display fatal error in case of file not found.

You can create your own simple unsafe html binding, of course if you use user input it could be a security risk.

App.directive('simpleHtml', function() {
  return function(scope, element, attr) {
    scope.$watch(attr.simpleHtml, function (value) {
      element.html(scope.$eval(attr.simpleHtml));
    })
  };
})

HTTP does not place a predefined limit on the length of each header field or on the length of the header section as a whole, as described in Section 2.5. Various ad hoc limitations on individual header field length are found in practice, often depending on the specific field semantics.

HTTP Header values are restricted by server implementations. Http specification doesn't restrict header size.

A server that receives a request header field, or set of fields, larger than it wishes to process MUST respond with an appropriate 4xx (Client Error) status code. Ignoring such header fields would increase the server's vulnerability to request smuggling attacks (Section 9.5).

Most servers will return 413 Entity Too Large or appropriate 4xx error when this happens.

A client MAY discard or truncate received header fields that are larger than the client wishes to process if the field semantics are such that the dropped value(s) can be safely ignored without changing the message framing or response semantics.

Uncapped HTTP header size keeps the server exposed to attacks and can bring down its capacity to serve organic traffic.

If you want to insert object, use this:

    currentLogs = [
 { socket_id: 'Server', message: 'Socketio online', data: 'Port  3333', logged: '2014-05-14 14:41:11' },
 { socket_id: 'Server', message: 'Waiting for Pi to connect...', data: 'Port: 8082', logged: '2014-05-14 14:41:11' }
];

console.warn(currentLogs.map(logs=>[ logs.socket_id , logs.message , logs.data , logs.logged ]));

The output will be:

[
  [ 'Server', 'Socketio online', 'Port  3333', '2014-05-14 14:41:11' ],
  [
    'Server',
    'Waiting for Pi to connect...',
    'Port: 8082',
    '2014-05-14 14:41:11'
  ]
]

Also, please check the documentation to know more about the map function.

Thought I'd add a bit to the answer.

If you have multiple URL definitions then you'll have to name each of them separately. So you lose the flexibility when calling reverse since one reverse will expect a parameter while the other won't.

Another way to use regex to accommodate the optional parameter:

r'^project_config/(?P<product>\w+)/((?P<project_id>\w+)/)?$'

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

@vigilante_stark's answer worked for me. It can be used to set a minimum "approximately" fixed margin in pixels. But in a responsive layout, when the width of the page is increasing margin can be increased by a percentage according to the given percentage as well. I used it as follows

example-class{
  margin: 0 calc(20px + 5%) 0 0;
}

If you are producing the DataTable from an SQL query, have you considered simply using Dapper instead?

Then, instead of making a SqlCommand with SqlParameters and a DataTable and a DataAdapter and on and on, which you then have to laboriously convert to a class, you just define the class, make the query column names match the field names, and the parameters are bound easily by name. You already have the TankReading class defined, so it will be really simple!

using Dapper;

// Below can be SqlConnection cast to DatabaseConnection, too.
DatabaseConnection connection = // whatever
IEnumerable<TankReading> tankReadings = connection.Query<TankReading>(
   "SELECT * from TankReading WHERE Value = @value",
   new { value = "tank1" } // note how `value` maps to `@value`
);
return tankReadings;

Now isn't that awesome? Dapper is very optimized and will give you darn near equivalent performance as reading directly with a DataAdapter.

If your class has any logic in it at all or is immutable or has no parameterless constructor, then you probably do need to have a DbTankReading class (as a pure POCO/Plain Old Class Object):

// internal because it should only be used in the data source project and not elsewhere
internal sealed class DbTankReading {
   int TankReadingsID { get; set; }
   DateTime? ReadingDateTime { get; set; }
   int ReadingFeet { get; set; }
   int ReadingInches { get; set; }
   string MaterialNumber { get; set; }
   string EnteredBy { get; set; }
   decimal ReadingPounds { get; set; }
   int MaterialID { get; set; }
   bool Submitted { get; set; }
}

You'd use that like this:

IEnumerable<TankReading> tankReadings = connection
   .Query<DbTankReading>(
      "SELECT * from TankReading WHERE Value = @value",
      new { value = "tank1" } // note how `value` maps to `@value`
   )
   .Select(tr => new TankReading(
      tr.TankReadingsID,
      tr.ReadingDateTime,
      tr.ReadingFeet,
      tr.ReadingInches,
      tr.MaterialNumber,
      tr.EnteredBy,
      tr.ReadingPounds,
      tr.MaterialID,
      tr.Submitted
   });

Despite the mapping work, this is still less painful than the data table method. This also lets you perform some kind of logic, though if the logic is any more than very simple straight-across mapping, I'd put the logic into a separate TankReadingMapper class.

sudo chmod -R ug+w .;

Basically, .git/objects file does not have write permissions. The above line grants permission to all the files and folders in the directory.

Taken from the docs here:

Adds or subtracts the specified amount of time to the given calendar field, based on the calendar's rules. For example, to subtract 5 days from the current time of the calendar, you can achieve it by calling:

Calendar calendar = Calendar.getInstance(); // this would default to now
calendar.add(Calendar.DAY_OF_MONTH, -5).

Jenkins has a 'Replay' feature, which enables you to quickly replay a job without updating sources:

The creators of java decided that the problems of multiple inheritance outweigh the benefits, so they did not include multiple inheritance. You can read about one of the largest issues of multiple inheritance (the double diamond problem) here.

The two most similar concepts are interface implementation and including objects of other classes as members of the current class. Using default methods in interfaces is almost exactly the same as multiple inheritance, however it is considered bad practice to use an interface with only default methods.

Probably the mymobileNO.titleLabel.text value doesn't include the scheme tel://

Your code should look like this:

NSString *phoneNumber = [@"tel://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

#!/bin/bash

req=$(curl -s -X GET http://host:8080/some/resource -H "Accept: application/json") 2>&1
echo "${req}"

r+ is the canonical mode for reading and writing at the same time. This is not different from using the fopen() system call since file() / open() is just a tiny wrapper around this operating system call.

Add list-style-position: inside to the ul element. (example)

The default value for the list-style-position property is outside.

ul {_x000D_
    text-align: center;_x000D_
    list-style-position: inside;_x000D_
}

<ul>_x000D_
    <li>one</li>_x000D_
    <li>two</li>_x000D_
    <li>three</li>_x000D_
</ul>

Another option (which yields slightly different results) would be to center the entire ul element:

.parent {_x000D_
  text-align: center;_x000D_
}_x000D_
.parent > ul {_x000D_
  display: inline-block;_x000D_
}

<div class="parent">_x000D_
  <ul>_x000D_
    <li>one</li>_x000D_
    <li>two</li>_x000D_
    <li>three</li>_x000D_
  </ul>_x000D_
</div>

Example:

If df and df_copy() are mixed-type pandas dataframes, you can apply the MultiColumnLabelEncoder() to the dtype=object columns in the following way:

# get `object` columns
df_object_columns = df.iloc[:, :].select_dtypes(include=['object']).columns
df_copy_object_columns = df_copy.iloc[:, :].select_dtypes(include=['object']).columns

# instantiate `MultiColumnLabelEncoder`
mcle = MultiColumnLabelEncoder(columns=object_columns)

# fit to `df` data
mcle.fit(df)

# transform the `df` data
mcle.transform(df)

# returns output like below
array([[1, 0, 0, ..., 1, 1, 0],
       [0, 5, 1, ..., 1, 1, 2],
       [1, 1, 1, ..., 1, 1, 2],
       ..., 
       [3, 5, 1, ..., 1, 1, 2],

# transform `df_copy` data
mcle.transform(df_copy)

# returns output like below (assuming the respective columns 
# of `df_copy` contain the same unique values as that particular 
# column in `df`
array([[1, 0, 0, ..., 1, 1, 0],
       [0, 5, 1, ..., 1, 1, 2],
       [1, 1, 1, ..., 1, 1, 2],
       ..., 
       [3, 5, 1, ..., 1, 1, 2],

# inverse `df` data
mcle.inverse_transform(df)

# outputs data like below
array([['August', 'Friday', '2013', ..., 'N', 'N', 'CA'],
       ['April', 'Tuesday', '2014', ..., 'N', 'N', 'NJ'],
       ['August', 'Monday', '2014', ..., 'N', 'N', 'NJ'],
       ..., 
       ['February', 'Tuesday', '2014', ..., 'N', 'N', 'NJ'],
       ['April', 'Tuesday', '2014', ..., 'N', 'N', 'NJ'],
       ['March', 'Tuesday', '2013', ..., 'N', 'N', 'NJ']], dtype=object)

# inverse `df_copy` data

Most apps are stored in /system/app which is readable without root my Evo, other apps are in /data/app which I needed root to see. The 'path' argument above would be something like: "/system/app/Weather.apk"

split your date into parts, then return a new Date with the adjusted values

function DateAdd(date, type, amount){
    var y = date.getFullYear(),
        m = date.getMonth(),
        d = date.getDate();
    if(type === 'y'){
        y += amount;
    };
    if(type === 'm'){
        m += amount;
    };
    if(type === 'd'){
        d += amount;
    };
    return new Date(y, m, d);
}

Remember that the months are zero based, but the days are not. ie new Date(2009, 1, 1) == 01 February 2009, new Date(2009, 1, 0) == 31 January 2009;

If you like python and have an option to install a package, you can use this utility that I made.

# install pythonp
python -m pip install pythonp

pythonp "5*5"
25

pythonp "1 / (1+math.exp(0.5))"
0.3775406687981454

# define a custom function and pass it to another higher-order function
pythonp "n=10;functools.reduce(lambda x,y:x*y, range(1,n+1))"

My understanding is that, for example, you wrongly saved a file you had updated for testing purposes only. Then, when you run "git status" the file appears as "Modified" and you say some bad words. You just want the old version back and continue to work normally.

In that scenario you can just run the following command:

git checkout -- path/filename

You're going to have to reformat your releases object to be an array of objects. Then you'll be able to sort them the way you're attempting.

Before you return your model from the controller, set your ReturnDate property to DateTime.Now()

myModel.ReturnDate = DateTime.Now()

return View(myModel)

Your view is not the right place to set values on properties so the controller is the better place for this.

You could even have it so that the getter on ReturnDate returns the current date/time.

private DateTime _returnDate = DateTime.MinValue;
public DateTime ReturnDate{
   get{
     return (_returnDate == DateTime.MinValue)? DateTime.Now() : _returnDate;
   }
   set{_returnDate = value;}
}

Ajay,

The reason that you can't see the other tables is that you need to log in as 'root' in order to see them

mysql -h localhost -u root

This is one of the few places that I disagree with the convention enough to go against it. TBH, I HATE that the definition of an enum and the instance of it can have the same name. I postfix all of my Enums with "Enum" specifically because it makes it clear what the context of it is in any given usage. IMO it makes the code much more readable.

public enum PersonTypesEnum {
    smart,
    sad,
    funny,
    angry
}


public class Person {   
    public PersonTypesEnum PersonType {get; set;}
}

Nobody will ever confuse what is the enum and what is the instance of it.

I hope people would allow them to turn things such as music off, as for button clicks, Sometimes, those are pretty cool. Use the

<audio controls autoplay hidden="hidden"> <source src="*file here*" type="*file extension (.mp3 .ogg etc.)*"> <!--This displays an error to users that don't have it supported--> Your browser does not support the audio element. </audio>

As you can see, I don't like to repeat myself much, But I decided with the hidden tag.

Hope this helps.

Put this line into your vimrc:

set nobk nowb noswf noudf " nobackup nowritebackup noswapfile noundofile

In windows that would be the:

C:\Program Files (x86)\vim\_vimrc

file for system-wide vim configuration for all users.

Setting the last one noundofile is important in Windows to prevent the creation of *~ tilda files after editing.

I wish Vim had that line included by default. Nobody likes ugly directories.

Let the user choose if and how she wants to enable advanced backup/undo file features first.

This is the most annoying part of Vim.

The next step might be setting up:

set noeb vb t_vb= " errorbells visualbell

to disable beeping in vim as well :-)

The other answers only show the changed files.

git log -p DIR is very useful, if you need the full diff of all changed files in a specific subdirectory.

Example: Show all detailed changes in a specific version range

git log -p 8a5fb..HEAD -- A B

I had this problem using GitExtensions on windows. Fixed by granting full permission for the current user (me) on the folder that contained the repo.

Another time, I even though I was getting the error from Git Extensions, I was able to commit the same files from Visual Studio 2015.

Another time I had to delete the "index" file from the .git folder

Past 10g the current answer no longer works for renaming views. The only method that still works is dropping and recreating the view. The best way I can think of to do this would be:

SELECT TEXT FROM ALL_VIEWS WHERE owner='some_schema' and VIEW_NAME='some_view';

Add this in front of the SQL returned

Create or replace view some_schema.new_view_name as ...

Drop the old view

Drop view some_schema.some_view;

This adds custom text at the beginning of your file:

echo 'your_custom_escaped_content' > temp_file.csv
cat testfile.csv >> temp_file.csv
mv temp_file.csv testfile.csv

I was injecting service like this:

private messageShowService MessageShowService

instead of:

private messageShowService: MessageShowService

and that was the reason of error, despite nothing related with ',' was there.

Try switching them:

return RedirectToAction("Account", "Login");

I tried it and it worked.

That because your csv file is in invalid format, maybe the line break in your text file is not the \n or \r

and, using c/c++ to parse text is not a good idea. try awk:

 $awk -F"," '{print "ID="$1"\tName="$2"\tAge="$3"\tGender="$4}' 1.csv
 ID=0   Name=Filipe Age=19  Gender=M
 ID=1   Name=Maria  Age=20  Gender=F
 ID=2   Name=Walter Age=60  Gender=M

Without the combined child selector you would probably do something similar to this:

foo {
  bar {
    baz {
      color: red;
    }
  }
}

If you want to reproduce the same syntax with >, you could to this:

foo {
  > bar {
    > baz {
      color: red;
    }
  }
}

This compiles to this:

foo > bar > baz {
  color: red;
}

Or in sass:

foo
  > bar
    > baz
      color: red

If you don't want use connection pool (you sure, that your app has only one connection), you can do this - if connection falls you must establish new one - call method .openSession() instead .getCurrentSession()

For example:

SessionFactory sf = null;
// get session factory
// ...
//
Session session = null;
try {
        session = sessionFactory.getCurrentSession();
} catch (HibernateException ex) {
        session = sessionFactory.openSession();
}

If you use Mysql, you can set autoReconnect property:

    <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1/database?autoReconnect=true</property>

I hope this helps.

You can use java.util.Calendar class to get time in milliseconds. Example:

Calendar cal = Calendar.getInstance();
int milliSec = cal.get(Calendar.MILLISECOND);
// print milliSec

java.util.Date date = cal.getTime();
System.out.println("Output: " +  new SimpleDateFormat("yyyy/MM/dd-HH:mm:ss:SSS").format(date));

To communicate a child component with another child component I've made a method in parent which calls a method in a child with:

this.$refs.childMethod()

And from the another child I've called the root method:

this.$root.theRootMethod()

It worked for me.

This is easily achieved either programmatically, in your code, or declaratively in either the web.config or the app.config.

You can programmatically create a proxy like so:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("[ultimate destination of your request]");
WebProxy myproxy = new WebProxy("[your proxy address]", [your proxy port number]);
myproxy.BypassProxyOnLocal = false;
request.Proxy = myproxy;
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse) request.GetResponse();

You're basically assigning the WebProxy object to the request object's proxy property. This request will then use the proxy you define.

To achieve the same thing declaratively, you can do the following:

<system.net>
  <defaultProxy>
    <proxy
      proxyaddress="http://[your proxy address and port number]"
      bypassonlocal="false"
    />
  </defaultProxy>
</system.net>

within your web.config or app.config. This sets a default proxy that all http requests will use. Depending upon exactly what you need to achieve, you may or may not require some of the additional attributes of the defaultProxy / proxy element, so please refer to the documentation for those.

I had found the easiest way to solve this question. If efficient you can use

A possible solution is the following; precondition is, that there are not conflicts in the used enum values. (e.g. when removing an enum value, be sure that this value is not used anymore.)

-- rename the old enum
alter type my_enum rename to my_enum__;
-- create the new enum
create type my_enum as enum ('value1', 'value2', 'value3');

-- alter all you enum columns
alter table my_table
  alter column my_column type my_enum using my_column::text::my_enum;

-- drop the old enum
drop type my_enum__;

Also in this way the column order will not be changed.

The first thing I'd look at is a database. However, serialization is an option. If you go for binary serialization, then I would avoid BinaryFormatter - it has a tendency to get angry between versions if you change fields etc. Xml via XmlSerialzier would be fine, and can be side-by-side compatible (i.e. with the same class definitions) with protobuf-net if you want to try contract-based binary serialization (giving you a flat file serializer without any effort).

just try this code:

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class CurrentTimeDateCalendar {
    public static void getCurrentTimeUsingDate() {
        Date date = new Date();
        String strDateFormat = "hh:mm:ss a";
        DateFormat dateFormat = new SimpleDateFormat(strDateFormat);
        String formattedDate= dateFormat.format(date);
        System.out.println("Current time of the day using Date - 12 hour format: " + formattedDate);
    }
    public static void getCurrentTimeUsingCalendar() {
        Calendar cal = Calendar.getInstance();
        Date date=cal.getTime();
        DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
        String formattedDate=dateFormat.format(date);
        System.out.println("Current time of the day using Calendar - 24 hour format: "+ formattedDate);
    }
}

which the sample output is:

Current time of the day using Date - 12 hour format: 11:13:01 PM

Current time of the day using Calendar - 24 hour format: 23:13:01

Using slicing, e.g. array = array[::-1], is a neat trick and very Pythonic, but a little obscure for newbies maybe. Using the reverse() method is a good way to go in day to day coding because it is easily readable.

However, if you need to reverse a list in place as in an interview question, you will likely not be able to use built in methods like these. The interviewer will be looking at how you approach the problem rather than the depth of Python knowledge, an algorithmic approach is required. The following example, using a classic swap, might be one way to do it:-

def reverse_in_place(lst):      # Declare a function
    size = len(lst)             # Get the length of the sequence
    hiindex = size - 1
    its = size/2                # Number of iterations required
    for i in xrange(0, its):    # i is the low index pointer
        temp = lst[hiindex]     # Perform a classic swap
        lst[hiindex] = lst[i]
        lst[i] = temp
        hiindex -= 1            # Decrement the high index pointer
    print "Done!"

# Now test it!!
array = [2, 5, 8, 9, 12, 19, 25, 27, 32, 60, 65, 1, 7, 24, 124, 654]

print array                    # Print the original sequence
reverse_in_place(array)        # Call the function passing the list
print array                    # Print reversed list


**The result:**
[2, 5, 8, 9, 12, 19, 25, 27, 32, 60, 65, 1, 7, 24, 124, 654]
Done!
[654, 124, 24, 7, 1, 65, 60, 32, 27, 25, 19, 12, 9, 8, 5, 2]

Note that this will not work on Tuples or string sequences, because strings and tuples are immutable, i.e., you cannot write into them to change elements.
