Actually, you can save you picture at any place. If you want to save in a public space, so any other application can access, use this code:

storageDir = new File(
    Environment.getExternalStoragePublicDirectory(
        Environment.DIRECTORY_PICTURES
    ), 
    getAlbumName()
);

The picture doesn't go to the album. To do this, you need to call a scan:

private void galleryAddPic() {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(mCurrentPhotoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    this.sendBroadcast(mediaScanIntent);
}

You can found more info at https://developer.android.com/training/camera/photobasics.html#TaskGallery

localStorage only supports strings. Use JSON.stringify() and JSON.parse().

var names = [];
names[0] = prompt("New member name?");
localStorage.setItem("names", JSON.stringify(names));

//...
var storedNames = JSON.parse(localStorage.getItem("names"));

If you get the IP address from a DHCP server, you can also set the server to send a DNS server. Or add the nameserver 8.8.8.8 into /etc/resolvconf/resolv.conf.d/base file. The information in this file is included in the resolver configuration file even when no interfaces are configured.

A variation of DixonD's excellent answer (above).

public static bool TryOpen(string path,
                           FileMode fileMode,
                           FileAccess fileAccess,
                           FileShare fileShare,
                           TimeSpan timeout,
                           out Stream stream)

    var endTime = DateTime.Now + timeout;

    while (DateTime.Now < endTime)
    {
        if (TryOpen(path, fileMode, fileAccess, fileShare, out stream))
            return true;
    }

    stream = null;
    return false;
}

public static bool TryOpen(string path,
                           FileMode fileMode,
                           FileAccess fileAccess,

private static bool FileIsLocked(IOException ioException)
{
    var errorCode = (uint)Marshal.GetHRForException(ioException);
    return errorCode == HRFileLocked || errorCode == HRPortionOfFileLocked;

Usage:

{
    Stream stream = null;

    try
    {
        var timeOut = TimeSpan.FromSeconds(1);

        if (!TryOpen(filePath,
                     FileMode.Open,
                     FileAccess.ReadWrite,
                     FileShare.ReadWrite,
                     timeOut,
                     out stream))
            return;

        // Use stream...
    }
    finally
    {
        if (stream != null)
            stream.Close();
    }
}

Since strings are lists of characters in Python, we can concatenate strings the same way we concatenate lists (with the + sign):

{{ var1 + '-' + var2 + '-' + var3 }}

If you want to pipe the resulting string to some filter, make sure you enclose the bits in parentheses:

e.g. To concatenate our 3 vars, and get a sha512 hash:

{{ (var1 + var2 + var3) | hash('sha512') }}

Note: this works on Ansible 2.3. I haven't tested it on earlier versions.

EJS by itself currently does not allow view partials. Express does.

Try this function in Excel:

Public Shared Function SPLITTEXT(Text As String, SplitAt As String, ReturnZeroBasedIndex As Integer) As String
        Dim s() As String = Split(Text, SplitAt)
        If ReturnZeroBasedIndex <= s.Count - 1 Then
            Return s(ReturnZeroBasedIndex)
        Else
            Return ""
        End If
    End Function

You use it like this:

First Name (A1) | Last Name (A2)

Value in cell A1 = Michael Zomparelli

I want the last name in column A2.

=SPLITTEXT(A1, " ", 1)

The last param is the zero-based index you want to return. So if you split on the space char then index 0 = Michael and index 1 = Zomparelli

The above function is a .Net function, but can easily be converted to VBA.

If you're on Linux, or have cygwin available on Windows, you can run the input XML through a simple sed script that will replace <Active>True</Active> with <Active>true</Active>, like so:

cat <your XML file> | sed 'sX<Active>True</Active>X<Active>true</Active>X' | xmllint --schema -

If you're not, you can still use a non-validating xslt pocessor (xalan, saxon etc.) to run a simple xslt transformation on the input, and only then pipe it to xmllint.

What the xsl should contain something like below, for the example you listed above (the xslt processor should be 2.0 capable):

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:output method="xml" indent="yes"/>
    <xsl:template match="/">
    <xsl:for-each select="XML">
        <xsl:for-each select="Active">
            <xsl:value-of select=" replace(current(), 'True','true')"/>
        </xsl:for-each>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

How about:

df . -B MB | tail -1 | awk {'print $4'} | cut -d'%' -f1

You may want to consider using SCLAlertView, alternative for UIAlertView or UIAlertController.

UIAlertController only works on iOS 8.x or above, SCLAlertView is a good option to support older version.

github to see the details

example:

let alertView = SCLAlertView()
alertView.addButton("First Button", target:self, selector:Selector("firstButton"))
alertView.addButton("Second Button") {
    print("Second button tapped")
}
alertView.showSuccess("Button View", subTitle: "This alert view has buttons")

The length of an array is available as

int l = array.length;

The size of a List is availabe as

int s = list.size();

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

// in the HTML code I used some razor
@Html.Hidden("RedirectTo", Url.Action("Action", "Controller"));

// now down in the script I do this
<script type="text/javascript">

var url = $("#RedirectTo").val();

$(document).ready(function () {
    $.ajax({
        dataType: 'json',
        type: 'POST',
        url: '/Controller/Action',
        success: function (result) {
            if (result.UserFriendlyErrMsg === 'Some Message') {
                // display a prompt
                alert("Message: " + result.UserFriendlyErrMsg);
                // redirect us to the new page
                location.href = url;
            }
            $('#friendlyMsg').html(result.UserFriendlyErrMsg);
        }
    });
</script>

Replacing backslash with forward slash worked for me on Windows.

It's now possible with new chrome update for version 47 for 2016 , you can see it through developer tools on the resources tab, select cookies and look for your cookie expiration date under "Expires/Max-age"

There was some good code posted that solved the problem better than !a != !b

Note that I had to add the BOOL_DETAIL_OPEN/CLOSE so it would work on MSVC 2010

/* From: http://groups.google.com/group/comp.std.c++/msg/2ff60fa87e8b6aeb

   [* = a ? !static_cast<bool>(b) : static_cast<bool>(b)]

   But what is this funny "(( a bool_xor b ))"? Well, you can create some
   macros that allow you such a strange syntax. Note that the
   double-brackets are part of the syntax and cannot be removed! The set of
   three macros (plus two internal helper macros) also provides bool_and
   and bool_or. That given, what is it good for? We have && and || already,
   why do we need such a stupid syntax? Well, && and || can't guarantee
   that the arguments are converted to bool and that you get a bool result.
     Think "operator overloads". Here's how the macros look like:

   Note: BOOL_DETAIL_OPEN/CLOSE added to make it work on MSVC 2010
  */

#define BOOL_DETAIL_AND_HELPER(x) static_cast<bool>(x):false
#define BOOL_DETAIL_XOR_HELPER(x) !static_cast<bool>(x):static_cast<bool>(x)

#define BOOL_DETAIL_OPEN (
#define BOOL_DETAIL_CLOSE )

#define bool_and BOOL_DETAIL_CLOSE ? BOOL_DETAIL_AND_HELPER BOOL_DETAIL_OPEN
#define bool_or BOOL_DETAIL_CLOSE ? true:static_cast<bool> BOOL_DETAIL_OPEN
#define bool_xor BOOL_DETAIL_CLOSE ? BOOL_DETAIL_XOR_HELPER BOOL_DETAIL_OPEN

If you want to avoid error cases, don't allow wc -l to see files with newlines (which it will count as 2+ files)

e.g. Consider a case where we have a single file with a single EOL character in it

> mkdir emptydir && cd emptydir
> touch $'file with EOL(\n) character in it'
> find -type f
./file with EOL(?) character in it
> find -type f | wc -l
2

Since at least gnu wc does not appear to have an option to read/count a null terminated list (except from a file), the easiest solution would just be to not pass it filenames, but a static output each time a file is found, e.g. in the same directory as above

> find -type f -exec printf '\n' \; | wc -l
1

Or if your find supports it

> find -type f -printf '\n' | wc -l
1 

Use this:

var startDate = new Date();
    startDate.setFullYear(startDate.getFullYear() - 1);

If you want to do this using regex, you could simply use a non-capturing group, to get the word "world" and then grab everything after, like so

(?:world).*

The example string is tested here

Step1: open ~/.bash_profile

Now a text editor opens:

Step2: variable name should be in capitals. in this example variable is NODE_ENV

Step3: export NODE_ENV=development

Save it and close.

Restart your system.

Done.

To check env variable: open terminal and type

echo $NODE_ENV 

By using org.apache.http.client.HttpClient also you can easily do this with more readable way as below.

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

Within try catch you can insert

// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", "12345"));
nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);

If you are Clion/anyOtherJetBrainsIDE user, and yourFile.exe cause this problem, just delete it and let the app create and link it with libs from a scratch. It helps.

I find Ghost Doc to be very useful.

GhostDoc is a free add-in for Visual Studio that automatically generates XML documentation comments for C#. Either by using existing documentation inherited from base classes or implemented interfaces, or by deducing comments from name and type of e.g. methods, properties or parameters.

if($("input:radio[name=test]").is(":checked")){
  //Code to append goes here
}

You can use default primary key (id) which auto increaments.

Note: When you use first design i.e. use default field (id) as a primary key, initialize object by mentioning column names. e.g.

class User(models.Model):
    user_name = models.CharField(max_length = 100)

then initialize,

user = User(user_name="XYZ")

if you initialize in following way,

user = User("XYZ")

then python will try to set id = "XYZ" which will give you error on data type.

PEP-8 recommends you indent lines to the opening parentheses if you put anything on the first line, so it should either be indenting to the opening bracket:

urlpatterns = patterns('',
                       url(r'^$', listing, name='investment-listing'))

or not putting any arguments on the starting line, then indenting to a uniform level:

urlpatterns = patterns(
    '',
    url(r'^$', listing, name='investment-listing'),
)

urlpatterns = patterns(
    '', url(r'^$', listing, name='investment-listing'))

I suggest taking a read through PEP-8 - you can skim through a lot of it, and it's pretty easy to understand, unlike some of the more technical PEPs.

The essential difference between /* and / is that a servlet with mapping /* will be selected before any servlet with an extension mapping (like *.html), while a servlet with mapping / will be selected only after extension mappings are considered (and will be used for any request which doesn't match anything else---it is the "default servlet").

In particular, a /* mapping will always be selected before a / mapping. Having either prevents any requests from reaching the container's own default servlet.

Either will be selected only after servlet mappings which are exact matches (like /foo/bar) and those which are path mappings longer than /* (like /foo/*). Note that the empty string mapping is an exact match for the context root (http://host:port/context/).

See Chapter 12 of the Java Servlet Specification, available in version 3.1 at http://download.oracle.com/otndocs/jcp/servlet-3_1-fr-eval-spec/index.html.

/**
 * @param filePath
 * @param fs
 * @return list of absolute file path present in given path
 * @throws FileNotFoundException
 * @throws IOException
 */
public static List<String> getAllFilePath(Path filePath, FileSystem fs) throws FileNotFoundException, IOException {
    List<String> fileList = new ArrayList<String>();
    FileStatus[] fileStatus = fs.listStatus(filePath);
    for (FileStatus fileStat : fileStatus) {
        if (fileStat.isDirectory()) {
            fileList.addAll(getAllFilePath(fileStat.getPath(), fs));
        } else {
            fileList.add(fileStat.getPath().toString());
        }
    }
    return fileList;
}

Quick Example : Suppose you have the following file structure:

a  ->  b
   ->  c  -> d
          -> e 
   ->  d  -> f

Using the code above, you get:

a/b
a/c/d
a/c/e
a/d/f

If you want only the leaf (i.e. fileNames), use the following code in else block :

 ...
    } else {
        String fileName = fileStat.getPath().toString(); 
        fileList.add(fileName.substring(fileName.lastIndexOf("/") + 1));
    }

This will give:

b
d
e
f

Numpy has a convenience function, np.fft.fftfreq to compute the frequencies associated with FFT components:

from __future__ import division
import numpy as np
import matplotlib.pyplot as plt

data = np.random.rand(301) - 0.5
ps = np.abs(np.fft.fft(data))**2

time_step = 1 / 30
freqs = np.fft.fftfreq(data.size, time_step)
idx = np.argsort(freqs)

plt.plot(freqs[idx], ps[idx])

Note that the largest frequency you see in your case is not 30 Hz, but

In [7]: max(freqs)
Out[7]: 14.950166112956811

You never see the sampling frequency in a power spectrum. If you had had an even number of samples, then you would have reached the Nyquist frequency, 15 Hz in your case (although numpy would have calculated it as -15).

Wrap cell content in a flex block. As a bonus, cell auto fits visible width.

For anyone looking for a concise, pictorial answer:

https://hanaskuliah.wordpress.com/2015/12/07/android-5-development-part-6-fragment/

And,

In your notebook (simple approach). Add new cell with following code

%%html
<style type='text/css'>
.CodeMirror{
    font-size: 12px;
}

div.output_area pre {
    font-size: 12px;
}
</style>

do this on a new thread (seperate it from main thread)

 new Thread(new Runnable() {
     @Override
     public void run() {
        // TODO Auto-generated method stub
     }
}).run();

The easiest and the most correct (and legal) way is to use graph api.

Just perform the request: http://graph.facebook.com/4

which returns

{
   "id": "4",
   "name": "Mark Zuckerberg",
   "first_name": "Mark",
   "last_name": "Zuckerberg",
   "link": "http://www.facebook.com/zuck",
   "username": "zuck",
   "gender": "male",
   "locale": "en_US"
}

and take the link key.

You can also reduce the traffic by using fields parameter: http://graph.facebook.com/4?fields=link to get only what you need:

{
   "link": "http://www.facebook.com/zuck",
   "id": "4"
}

This does exist, but it's actually a feature of git log:

git log -p [--follow] [-1] <path>

Note that -p can also be used to show the inline diff from a single commit:

git log -p -1 <commit>

Options used:

• -p (also -u or --patch) is hidden deeeeeeeep in the git-log man page, and is actually a display option for git-diff. When used with log, it shows the patch that would be generated for each commit, along with the commit information—and hides commits that do not touch the specified <path>. (This behavior is described in the paragraph on --full-diff, which causes the full diff of each commit to be shown.)
• -1 shows just the most recent change to the specified file (-n 1 can be used instead of -1); otherwise, all non-zero diffs of that file are shown.
• --follow is required to see changes that occurred prior to a rename.

As far as I can tell, this is the only way to immediately see the last set of changes made to a file without using git log (or similar) to either count the number of intervening revisions or determine the hash of the commit.

To see older revisions changes, just scroll through the log, or specify a commit or tag from which to start the log. (Of course, specifying a commit or tag returns you to the original problem of figuring out what the correct commit or tag is.)

Credit where credit is due:

• I discovered log -p thanks to this answer.
• Credit to FranciscoPuga and this answer for showing me the --follow option.
• Credit to ChrisBetti for mentioning the -n 1 option and atatko for mentioning the -1 variant.
• Credit to sweaver2112 for getting me to actually read the documentation and figure out what -p "means" semantically.

You can do something like this,

  Dim lstOfStrings As New List(Of String) From {"Value1", "Value2", "Value3"}

Collection Initializers

In Java 8 you can use the Stream interface:

return dvdList.stream().anyMatch(d -> d.getTitle().equalsIgnoreCase("SomeTitle"));

In my case, its Password was longer than 100 characters. Setting it to a smaller character password worked.

Actually I am wondering is there a reference somewhere to that.

There are several reasons you could have problems loading from lib - see here for details - http://www.williambharding.com/blog/technology/rails-3-autoload-modules-and-classes-in-production/

• fix autoload path
• threadsafe related
• naming relating
• ...

You can simply use ORS dynamically like this:

awk '{ORS="" ; print($1" "$2" "$3" "$4" "$5" "); ORS="\n"; print($6-=2*$6)}' file_in > file_out

Regarding existing answers, note that signal handling is platform dependent. Win32 for example handles far fewer signals than POSIX operating systems; see here. While SIGINT is declared in signals.h on Win32, see the note in the documentation that explains that it will not do what you might expect.

<?php
$output = file_get_contents('http://host/path/another.php?param=value ');

It is not very nice to use native php resources like $_GET as Laravel gives us easy ways to get the variables. As a matter of standard, whenever possible use the resources of the laravel itself instead of pure PHP.

There is at least two modes to get variables by GET in Laravel ( Laravel 5.x or greater):

Mode 1

Route:

Route::get('computers={id}', 'ComputersController@index');

Request (POSTMAN or client...):

http://localhost/api/computers=500

Controler - You can access the {id} paramter in the Controlller by:

public function index(Request $request, $id){
   return $id;
}

Mode 2

Route:

Route::get('computers', 'ComputersController@index');

Request (POSTMAN or client...):

http://localhost/api/computers?id=500

Controler - You can access the ?id paramter in the Controlller by:

public function index(Request $request){
   return $request->input('id');
}

If you want to delete a commit you can do it as part of an interactive rebase. But do it with caution, so you don't end up messing up your repo.

In Sourcetree:

1. Right click a commit that's older than the one you want to delete, and choose "Rebase children of xxxx interactively...". The one you click will be your "base" and you can make changes to every commit made after that one.

2. In the new window, select the commit you want gone, and press the "Delete"-button at the bottom, or right click the commit and click "Delete commit".
3. List item
4. Click "OK" (or "Cancel" if you want to abort).

Check out this Atlassian blog post for more on interactive rebasing in Sourcetree.

You can do this with redux-thunk. There is a guide in redux document for async actions like setTimeout.

It will shift the bits by padding that many 0's.

For ex,

• binary 10 which is digit 2 left shift by 2 is 1000 which is digit 8
• binary 10 which is digit 2 left shift by 3 is 10000 which is digit 16

ActiveXObject is available only on IE browser. So every other useragent will throw an error

On modern browser you could use instead File API or File writer API (currently implemented only on Chrome)

Make 'maven.test.skip' as false in pom file, while building project test reource will come under test-classes.

<maven.test.skip>false</maven.test.skip>

It is also worth noting that ListView may not display as expected without first changing the property:

myListView.View = View.Details; // or View.List

For me Visual Studio seems to default it to View.LargeIcon for some reason so nothing appears until it is changed.

Complete code to show a single column in a ListView and allow space for a vertical scroll bar.

lisSerials.Items.Clear();
lisSerials.View = View.Details;
lisSerials.FullRowSelect = true;

// add column if not already present
if(lisSerials.Columns.Count==0)
{
    int vw = SystemInformation.VerticalScrollBarWidth;
    lisSerials.Columns.Add("Serial Numbers", lisSerials.Width-vw-5);
}

foreach (string s in stringArray)
{
    ListViewItem lvi = new ListViewItem(new string[] { s });
    lisSerials.Items.Add(lvi);
}

Nobody has mentioned GetPerformanceInfo yet. PInvoke signatures are available.

This function makes the following system-wide information available:

• CommitTotal
• CommitLimit
• CommitPeak
• PhysicalTotal
• PhysicalAvailable
• SystemCache
• KernelTotal
• KernelPaged
• KernelNonpaged
• PageSize
• HandleCount
• ProcessCount
• ThreadCount

PhysicalTotal is what the OP is looking for, although the value is the number of pages, so to convert to bytes, multiply by the PageSize value returned.

function addHidden(theForm, key, value) {
    // Create a hidden input element, and append it to the form:
    var input = document.createElement('input');
    input.type = 'hidden';
    input.name = key; //name-as-seen-at-the-server
    input.value = value;
    theForm.appendChild(input);

// Form reference:
var theForm = document.forms['detParameterForm'];

// Add data:
addHidden(theForm, 'key-one', 'value');

You are asking to initialize four variables using a single float object, which of course is not iterable. You can do -

1. grade_1, grade_2, grade_3, grade_4 = [0.0 for _ in range(4)]
2. grade_1 = grade_2 = grade_3 = grade_4 = 0.0

Unless you want to initialize them with different values of course.

To avoid a panic on a zero length input, wrap the truncate operation in an if

input, _ := src.ReadString('\n')
var inputFmt string
if len(input) > 0 {
    inputFmt = input[:len(input)-1]
}
// Do something with inputFmt

On my CentOS 6 I have two openssl.cnf :

/openvpn/easy-rsa/
/pki/tls/

isEmpty() is included in the S4Vectors base package. No need to load any other packages.

a <- which(1:3 == 5)
isEmpty(a)
# [1] TRUE

I'm guessing that you meant to do this:

msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]
# To concatenate strings in python, use       ^ 

Since others have already mentioned all the possible solutions, I am sharing my workaround solution.

In my situation with Postgres 9.4, while working with Jackson,

//Convert it to named native query.
List<String> list = em.createNativeQuery("select cast(array_to_json(array_agg(row_to_json(a))) as text) from myschema.actors a")
                   .getResultList();

List<ActorProxy> map = new ObjectMapper().readValue(list.get(0), new TypeReference<List<ActorProxy>>() {});

I am sure you can find same for other databases.

Also FYI, JPA 2.0 native query results as map

I think this is a simple answer , this will split child devs 50% each based on the parent width.

 <div style="width: 100%">
        <div style="width: 50%; float: left; display: inline-block;">
            Hello world
        </div>
        <div style="width: 50%; display: inline-block;">
            Hello world
        </div>
    </div>

Change your onCreateOptionsMenu method to return true. To quote the docs:

You must return true for the menu to be displayed; if you return false it will not be shown.

A list of the few remaining cosmetic and packaging differences between Oracle JDK 11 and OpenJDK 11 can be found in this blog post:

https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later

In short:

• Oracle JDK 11 emits a warning when using the -XX:+UnlockCommercialFeatures option,
• it can be configured to provide usage log data to the “Advanced Management Console” tool,
• it has always required third party cryptographic providers to be signed by a known certificate,
• it will continue to include installers, branding and JRE packaging,
• while the javac --release command behaves slightly differently for the Java 9 and Java 10 targets, and
• the output of the java --version and java -fullversion commands will distinguish Oracle JDK builds from OpenJDK builds.

Let's assume you want to overwrite the same file:

import json

with open('data.json', 'r') as data_file:
    data = json.load(data_file)

for element in data:
    element.pop('hours', None)

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

dict.pop(<key>, not_found=None) is probably what you where looking for, if I understood your requirements. Because it will remove the hours key if present and will not fail if not present.

However I am not sure I understand why it makes a difference to you whether the hours key contains some days or not, because you just want to get rid of the whole key / value pair, right?

Now, if you really want to use del instead of pop, here is how you could make your code work:

import json

with open('data.json') as data_file:
    data = json.load(data_file)

for element in data:
    if 'hours' in element:
        del element['hours']

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

EDIT So, as you can see, I added the code to write the data back to the file. If you want to write it to another file, just change the filename in the second open statement.

I had to change the indentation, as you might have noticed, so that the file has been closed during the data cleanup phase and can be overwritten at the end.

with is what is called a context manager, whatever it provides (here the data_file file descriptor) is available ONLY within that context. It means that as soon as the indentation of the with block ends, the file gets closed and the context ends, along with the file descriptor which becomes invalid / obsolete.

Without doing this, you wouldn't be able to open the file in write mode and get a new file descriptor to write into.

I hope it's clear enough...

SECOND EDIT

This time, it seems clear that you need to do this:

with open('dest_file.json', 'w') as dest_file:
    with open('source_file.json', 'r') as source_file:
        for line in source_file:
            element = json.loads(line.strip())
            if 'hours' in element:
                del element['hours']
            dest_file.write(json.dumps(element))

The fastest way to do that is with forEach =)

var fillArray = Array.prototype.forEach
    ? function(arr, n) {
         arr.forEach(function(_, index) { arr[index] = n; });
         return arr;
      }
    : function(arr, n) {
         var len = arr.length;
         arr.length = 0;
         while(len--) arr.push(n);
         return arr;
      };

// test
fillArray([1,2,3], 'X'); // => ['X', 'X', 'X']

You can add manually in the manifest file within manifest tag by:

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

This permission is required to be able to access the camera device.

Oh my God! It is not that much complicated, with these answers which also works. However, other answers tho this question also works well.

If you really want to use the vue-cli-service and if you want to have the port setting in your package.json file, which your 'vue create <app-name>' command basically creates, you can use the following configuration: --port 3000. So the whole configuration of your script would be like this:

...
"scripts": {
"serve": "vue-cli-service serve --port 3000",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint"
},
...

I am using @vue/cli 4.3.1 (vue --version) on a macOS device.

I have also added the vue-cli-service reference: https://cli.vuejs.org/guide/cli-service.html

Use this:

$('#navigation ul li').css('display', 'inline-block');

Also, as others have stated, if you want to make multiple css changes at once, that's when you would add the curly braces (for object notation), and it would look something like this (if you wanted to change, say, 'background-color' and 'position' in addition to 'display'):

$('#navigation ul li').css({'display': 'inline-block', 'background-color': '#fff', 'position': 'relative'}); //The specific CSS changes after the first one, are, of course, just examples.

The solutions here didn't work for me as I'm styling react components.

What worked though for the sidebar was

.sidebar{
position: sticky;
top: 0;
}

Hope this helps someone.

Simply use it like below

 $('#isAgeSelected').change(function() {
     if ($(this).is(":checked")) { // or if($("#isAgeSelected").attr('checked') == true){
         $('#txtAge').show();
     } else {
         $('#txtAge').hide();
     }
 });

You can use CSS to select a range; in this case, you want list items 1-9:

ol li:nth-child(n+1):nth-child(-n+9) 

Then adjust margins on those first items appropriately:

ol li:nth-child(n+1):nth-child(-n+9) { margin-left: .55em; }
ol li:nth-child(n+1):nth-child(-n+9) em,
ol li:nth-child(n+1):nth-child(-n+9) span { margin-left: 19px; }

Here's how I "automate" Dropping connected users in Oracle database:

# A shell script to Drop a Database Schema, forcing off any Connected Sessions (for example, before an Import) 
# Warning! With great power comes great responsibility.
# It is often advisable to take an Export before Dropping a Schema

if [ "$1" = "" ] 
then
    echo "Which Schema?"
    read schema
else
    echo "Are you sure? (y/n)"
    read reply
    [ ! $reply = y ] && return 1
    schema=$1
fi

sqlplus / as sysdba <<EOF
set echo on
alter user $schema account lock;
-- Exterminate all sessions!
begin     
  for x in ( select sid, serial# from v\$session where username=upper('$schema') )
  loop  
   execute immediate ( 'alter system kill session '''|| x.Sid || ',' || x.Serial# || ''' immediate' );  
  end loop;  
  dbms_lock.sleep( seconds => 2 ); -- Prevent ORA-01940: cannot drop a user that is currently connected
end;
/
drop user $schema cascade;
quit
EOF

This might be a bit more readable:

Date min, max;   // assume these are set to something
Date d;          // the date in question

return d.after(min) && d.before(max);

$objPHPExcel
->getActiveSheet()
->getStyle('A1')
->getFill()
->setFillType(PHPExcel_Style_Fill::FILL_SOLID)
->getStartColor()
->setRGB('colorcode'); //i.e,colorcode=D3D3D3

I am using Mac and none of the answers above helped me. I found out that maven loads its own JAVA_HOME from the path specified in: ~/.mavenrc

I changed the content of the file to be: JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home

For Linux it will look something like:
JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre

Here are some real-world examples of the types of relationships:

One-to-one (1:1)

A relationship is one-to-one if and only if one record from table A is related to a maximum of one record in table B.

To establish a one-to-one relationship, the primary key of table B (with no orphan record) must be the secondary key of table A (with orphan records).

For example:

CREATE TABLE Gov(
    GID number(6) PRIMARY KEY, 
    Name varchar2(25), 
    Address varchar2(30), 
    TermBegin date,
    TermEnd date
); 

CREATE TABLE State(
    SID number(3) PRIMARY KEY,
    StateName varchar2(15),
    Population number(10),
    SGID Number(4) REFERENCES Gov(GID), 
    CONSTRAINT GOV_SDID UNIQUE (SGID)
);

INSERT INTO gov(GID, Name, Address, TermBegin) 
values(110, 'Bob', '123 Any St', '1-Jan-2009');

INSERT INTO STATE values(111, 'Virginia', 2000000, 110);

One-to-many (1:M)

A relationship is one-to-many if and only if one record from table A is related to one or more records in table B. However, one record in table B cannot be related to more than one record in table A.

To establish a one-to-many relationship, the primary key of table A (the "one" table) must be the secondary key of table B (the "many" table).

For example:

CREATE TABLE Vendor(
    VendorNumber number(4) PRIMARY KEY,
    Name varchar2(20),
    Address varchar2(20),
    City varchar2(15),
    Street varchar2(2),
    ZipCode varchar2(10),
    Contact varchar2(16),
    PhoneNumber varchar2(12),
    Status varchar2(8),
    StampDate date
);

CREATE TABLE Inventory(
    Item varchar2(6) PRIMARY KEY,
    Description varchar2(30),
    CurrentQuantity number(4) NOT NULL,
    VendorNumber number(2) REFERENCES Vendor(VendorNumber),
    ReorderQuantity number(3) NOT NULL
);

Many-to-many (M:M)

A relationship is many-to-many if and only if one record from table A is related to one or more records in table B and vice-versa.

To establish a many-to-many relationship, create a third table called "ClassStudentRelation" which will have the primary keys of both table A and table B.

CREATE TABLE Class(
    ClassID varchar2(10) PRIMARY KEY, 
    Title varchar2(30),
    Instructor varchar2(30), 
    Day varchar2(15), 
    Time varchar2(10)
);

CREATE TABLE Student(
    StudentID varchar2(15) PRIMARY KEY, 
    Name varchar2(35),
    Major varchar2(35), 
    ClassYear varchar2(10), 
    Status varchar2(10)
);  

CREATE TABLE ClassStudentRelation(
    StudentID varchar2(15) NOT NULL,
    ClassID varchar2(14) NOT NULL,
    FOREIGN KEY (StudentID) REFERENCES Student(StudentID), 
    FOREIGN KEY (ClassID) REFERENCES Class(ClassID),
    UNIQUE (StudentID, ClassID)
);

Shortcut

\d for show all tables

\d tablename to describe table

\? for more shortcuts for redshift

This didn't work for me.

sudo chmod -R 777 /path/to/your/file/or/directory

I used -f also.

sudo chmod -R -f 777 /path/to/your/file/or/directory

You need rawQuery method.

Example:

private final String MY_QUERY = "SELECT * FROM table_a a INNER JOIN table_b b ON a.id=b.other_id WHERE b.property_id=?";

db.rawQuery(MY_QUERY, new String[]{String.valueOf(propertyId)});

Use ? bindings instead of putting values into raw sql query.

Use jQuery ajax:

function AddToCart(id)
{
   $.ajax({
      url: 'urlToController',
      data: { id: id }
   }).done(function() {
      alert('Added'); 
   });
}

Dynamic solution

['color', 'height'].reduce((a,b) => (a[b]=elmo[b],a), {})

let subset= (obj,keys)=> keys.reduce((a,b)=> (a[b]=obj[b],a),{});_x000D_
_x000D_
_x000D_
// TEST_x000D_
_x000D_
let elmo = { _x000D_
  color: 'red',_x000D_
  annoying: true,_x000D_
  height: 'unknown',_x000D_
  meta: { one: '1', two: '2'}_x000D_
};_x000D_
_x000D_
console.log( subset(elmo, ['color', 'height']) );

Chinese Remainder Theorem comes to mind as an initial point as 221 = 13 * 17. So, break this down into 2 parts that get combined in the end, one for mod 13 and one for mod 17. Second, I believe there is some proof of a^(p-1) = 1 mod p for all non zero a which also helps reduce your problem as 5^55 becomes 5^3 for the mod 13 case as 13*4=52. If you look under the subject of "Finite Fields" you may find some good results on how to solve this.

EDIT: The reason I mention the factors is that this creates a way to factor zero into non-zero elements as if you tried something like 13^2 * 17^4 mod 221, the answer is zero since 13*17=221. A lot of large numbers aren't going to be prime, though there are ways to find large primes as they are used a lot in cryptography and other areas within Mathematics.

In typescript, the declaration is something like this:

const regex : RegExp = /.+\*.+/;

using RegExp constructor:

const regex = new RegExp('.+\\*.+');

The issue is in your registration app. It seems django-registration calls get_user_module() in models.py at a module level (when models are still being loaded by the application registration process). This will no longer work:

try:
    from django.contrib.auth import get_user_model
    User = get_user_model()
except ImportError:
    from django.contrib.auth.models import User    

I'd change this models file to only call get_user_model() inside methods (and not at module level) and in FKs use something like:

user = ForeignKey(settings.AUTH_USER_MODEL)

BTW, the call to django.setup() shouldn't be required in your manage.py file, it's called for you in execute_from_command_line. (source)

It looks like your TimeStamp is being set to the timezone of the originating system.

This is deprecated, but it should work:

cal.setTimeInMillis(ts_.getTime() - ts_.getTimezoneOffset());

The non-deprecated way is to use

Calendar.get(Calendar.ZONE_OFFSET) + Calendar.get(Calendar.DST_OFFSET)) / (60 * 1000)

but that would need to be done on the client side, since that system knows what timezone it is in.

Like thousands of people, I'm looking for this question:
Can run multiple queries simultaneously, and if there was one error, none would run I went to this page everywhere
But although the friends here gave good answers, these answers were not good for my problem
So I wrote a function that works well and has almost no problem with sql Injection.
It might be helpful for those who are looking for similar questions so I put them here to use

function arrayOfQuerys($arrayQuery)
{
    $mx = true;
    $conn->beginTransaction();
    try {
        foreach ($arrayQuery AS $item) {
            $stmt = $conn->prepare($item["query"]);
            $stmt->execute($item["params"]);
            $result = $stmt->rowCount();
            if($result == 0)
                $mx = false;
         }
         if($mx == true)
             $conn->commit();
         else
             $conn->rollBack();
    } catch (Exception $e) {
        $conn->rollBack();
        echo "Failed: " . $e->getMessage();
    }
    return $mx;
}

for use(example):

 $arrayQuery = Array(
    Array(
        "query" => "UPDATE test SET title = ? WHERE test.id = ?",
        "params" => Array("aa1", 1)
    ),
    Array(
        "query" => "UPDATE test SET title = ? WHERE test.id = ?",
        "params" => Array("bb1", 2)
    )
);
arrayOfQuerys($arrayQuery);

and my connection:

    try {
        $options = array(
            //For updates where newvalue = oldvalue PDOStatement::rowCount()   returns zero. You can use this:
            PDO::MYSQL_ATTR_FOUND_ROWS => true
        );
        $conn = new PDO("mysql:host=$servername;dbname=$database", $username, $password, $options);
        $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    } catch (PDOException $e) {
        echo "Error connecting to SQL Server: " . $e->getMessage();
    }

Note:
This solution helps you to run multiple statement together,
If an incorrect a statement occurs, it does not execute any other statement

This is a step-by-step procedure to get pkg-config working on Windows, based on my experience, using the info from Oliver Zendel's comment.

I assume here that MinGW was installed to C:\MinGW. There were multiple versions of the packages available, and in each case I just downloaded the latest version.

1. go to http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/
2. download the file pkg-config_0.26-1_win32.zip
3. extract the file bin/pkg-config.exe to C:\MinGW\bin
4. download the file gettext-runtime_0.18.1.1-2_win32.zip
5. extract the file bin/intl.dll to C:\MinGW\bin
6. go to http://ftp.gnome.org/pub/gnome/binaries/win32/glib/2.28
7. download the file glib_2.28.8-1_win32.zip
8. extract the file bin/libglib-2.0-0.dll to C:\MinGW\bin

Now CMake will be able to use pkg-config if it is configured to use MinGW.

The below code works fine but I am not sure about the radio button and dropdown list

$( '#form_id' ).submit( function( event ) {
    event.preventDefault();

    //validate fields
    var fail = false;
    var fail_log = '';
    var name;
    $( '#form_id' ).find( 'select, textarea, input' ).each(function(){
        if( ! $( this ).prop( 'required' )){

        } else {
            if ( ! $( this ).val() ) {
                fail = true;
                name = $( this ).attr( 'name' );
                fail_log += name + " is required \n";
            }

        }
    });

    //submit if fail never got set to true
    if ( ! fail ) {
        //process form here.
    } else {
        alert( fail_log );
    }

});

It's not clear what you're actually trying to achieve, but here are two alternatives:

class E
{
public:
    struct X
    {
        int v;
    };

    // 1. (a) Instantiate an 'X' within 'E':
    X x;
};

int main()
{
    // 1. (b) Modify the 'x' within an 'E':
    E e;
    e.x.v = 9;

    // 2. Instantiate an 'X' outside 'E':
    E::X x;
    x.v = 10;
}

1. Where does user.id go after passport.serializeUser has been called?

The user id (you provide as the second argument of the done function) is saved in the session and is later used to retrieve the whole object via the deserializeUser function.

serializeUser determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}

2. We are calling passport.deserializeUser right after it where does it fit in the workflow?

The first argument of deserializeUser corresponds to the key of the user object that was given to the done function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc). In deserializeUser that key is matched with the in memory array / database or any data resource.

The fetched object is attached to the request object as req.user

Visual Flow

passport.serializeUser(function(user, done) {
    done(null, user.id);
});              ¦
                 ¦ 
                 ¦
                 +--------------------? saved to session
                                   ¦    req.session.passport.user = {id: '..'}
                                   ¦
                                   ?           
passport.deserializeUser(function(id, done) {
                   +---------------+
                   ¦
                   ? 
    User.findById(id, function(err, user) {
        done(err, user);
    });            +--------------? user object attaches to the request as req.user   
});

To merge a local directory into a directory within an image, do this. It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.

COPY ./files/. /files/

this problem can be solved by installing the latest libstdc++.

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get update
$ sudo apt-get install libstdc++6-7-dbg

class ArrayComparator implements Comparator<Comparable[]> {
    private final int columnToSort;
    private final boolean ascending;

    public ArrayComparator(int columnToSort, boolean ascending) {
        this.columnToSort = columnToSort;
        this.ascending = ascending;
    }

    public int compare(Comparable[] c1, Comparable[] c2) {
        int cmp = c1[columnToSort].compareTo(c2[columnToSort]);
        return ascending ? cmp : -cmp;
    }
}

This way you can handle any type of data in those arrays (as long as they're Comparable) and you can sort any column in ascending or descending order.

String[][] data = getData();
Arrays.sort(data, new ArrayComparator(0, true));

PS: make sure you check for ArrayIndexOutOfBounds and others.

EDIT: The above solution would only be helpful if you are able to actually store a java.util.Date in the first column or if your date format allows you to use plain String comparison for those values. Otherwise, you need to convert that String to a Date, and you can achieve that using a callback interface (as a general solution). Here's an enhanced version:

class ArrayComparator implements Comparator<Object[]> {
    private static Converter DEFAULT_CONVERTER = new Converter() {
        @Override
        public Comparable convert(Object o) {
            // simply assume the object is Comparable
            return (Comparable) o;
        }
    };
    private final int columnToSort;
    private final boolean ascending;
    private final Converter converter;


    public ArrayComparator(int columnToSort, boolean ascending) {
        this(columnToSort, ascending, DEFAULT_CONVERTER);
    }

    public ArrayComparator(int columnToSort, boolean ascending, Converter converter) {
        this.columnToSort = columnToSort;
        this.ascending = ascending;
        this.converter = converter;
    }

    public int compare(Object[] o1, Object[] o2) {
        Comparable c1 = converter.convert(o1[columnToSort]);
        Comparable c2 = converter.convert(o2[columnToSort]);
        int cmp = c1.compareTo(c2);
        return ascending ? cmp : -cmp;
    }

}

interface Converter {
    Comparable convert(Object o);
}

class DateConverter implements Converter {
    private static final DateFormat df = new SimpleDateFormat("yyyy.MM.dd hh:mm");

    @Override
    public Comparable convert(Object o) {
        try {
            return df.parse(o.toString());
        } catch (ParseException e) {
            throw new IllegalArgumentException(e);
        }
    }
}

And at this point, you can sort on your first column with:

Arrays.sort(data, new ArrayComparator(0, true, new DateConverter());

I skipped the checks for nulls and other error handling issues.

I agree this is starting to look like a framework already. :)

Last (hopefully) edit: I only now realize that your date format allows you to use plain String comparison. If that is the case, you don't need the "enhanced version".

Have you tried this?:

    $string = '';
    while($row = mysql_fetch_array($result))
    {
    //this will combine all the results into one string
    $string .= '<img src="'.$row['name'].'" />
                <div>'.$row['name'].'</div>
                <div>'.$row['title'].'</div>
                <div>'.$row['description'].'</div>
                <div>'.$row['link'].'</div><br />';

    //or this will add the individual result in an array
 /*
     $yourHtml[] = $row;
*/
    }

then you echo the $tring to the place you want it to be

<div id="place_here">
   <?php echo $string; ?>
   <?php 
     //or
    /*
      echo '<img src="'.$yourHtml[0]['name'].'" />;//change the index, or you just foreach loop it
    */
    ?>
</div>

no different, as declare in javadoc:

public boolean add(E e) {
    return offer(e);
}

Today I got this error, and after debugging I figured out that the actual tables were misssing, which I was referring using synonyms. So I suggest - first check that whether the tables exists!! :-))

It happens because you call it before DOM has loaded. Firstly, create the element and add atrributes to it, then after DOM has loaded call it. In your case it should look like that:

var canvas = document.createElement('canvas');
canvas.id     = "CursorLayer";
canvas.width  = 1224;
canvas.height = 768;
canvas.style.zIndex   = 8;
canvas.style.position = "absolute";
canvas.style.border   = "1px solid";
window.onload = function() {
    document.getElementById("CursorLayer");
}

Microsoft explains it in the KB305703 article on How to start the default Internet browser programmatically by using Visual C#.

Don't forget to check the Troubleshooting section.

find /opt/tomcat/log/ -type f -mtime +7 -name "*.bz2" -exec rm -f {} ";"

because Tomcat rotate needs one day delay.

I think your problem is likely related to your spring.config.location not ending the path with "/".

Quote the docs

If spring.config.location contains directories (as opposed to files) they should end in / (and will be appended with the names generated from spring.config.name before being loaded).

http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-external-config-application-property-files

You should also look at new triggers.

MySQL doesn't show the table name in the error, so you're really left in a lurch. Here's a working example:

use test;
create table blah (id int primary key AUTO_INCREMENT, data varchar(100));
create table audit_blah (audit_id int primary key AUTO_INCREMENT, action enum('INSERT','UPDATE','DELETE'), id int, data varchar(100) null);
insert into audit_blah(action, id, data) values ('INSERT', 1, 'a');
select * from blah;
select * from audit_blah;
truncate table audit_blah;

delimiter //
/* I've commented out "id" below, so the insert fails with an ambiguous error: */
create trigger ai_blah after insert on blah for each row 
begin 
  insert into audit_blah (action, /*id,*/ data) values ('INSERT', /*NEW.id,*/ NEW.data);
end;//

/* This insert is valid, but you'll get an exception from the trigger: */
insert into blah (data) values ('data1');

I realize that this is an old question, but I'll post the solution for my use case, in case others run into the same situation I did when implementing James Hill's answer (above).

I found this question while trying to solve the same issue. James' answer got me 90% there. However, for my use case, selecting the item from the dropdown also triggered an action on the page from dropdown's onchange event. James' code as written did not trigger this event (at least in Firefox, which I was testing in). As a result, I made the following minor change:

function setSelectedValue(object, value) {
    for (var i = 0; i < object.options.length; i++) {
        if (object.options[i].text === value) {
            object.options[i].selected = true;
            object.onchange();
            return;
        }
    }

    // Throw exception if option `value` not found.
    var tag = object.nodeName;
    var str = "Option '" + value + "' not found";

    if (object.id != '') {
        str = str + " in //" + object.nodeName.toLowerCase()
              + "[@id='" + object.id + "']."
    }

    else if (object.name != '') {
        str = str + " in //" + object.nodeName.toLowerCase()
              + "[@name='" + object.name + "']."
    }

    else {
        str += "."
    }

    throw str;
}

Note the object.onchange() call, which I added to the original solution. This calls the handler to make certain that the action on the page occurs.

Edit

Added code to throw an exception if option value is not found; this is needed for my use case.

Ended up creating array specific methods to do this. Much like the encoding/binary package with specific methods for each int type. For example binary.BigEndian.PutUint16([]byte, uint16).

func byte16PutString(s string) [16]byte {
    var a [16]byte
    if len(s) > 16 {
        copy(a[:], s)
    } else {
        copy(a[16-len(s):], s)
    }
    return a
}

var b [16]byte
b = byte16PutString("abc")
fmt.Printf("%v\n", b)

Output:

[0 0 0 0 0 0 0 0 0 0 0 0 0 97 98 99]

Notice how I wanted padding on the left, not the right.

You can change it by going File => Settings (Shortcut CTRL+ ALT+ S) , from Left panel Choose Appearance , Now from Right Panel choose theme.

Android Studio 2.1

Preference -> Search for Appearance -> UI options , Click on DropDown Theme

Android 2.2

Android studio -> File -> Settings -> Appearance & Behavior -> Look for UI Options

EDIT :

Import External Themes

You can download custom theme from this website. Choose your theme, download it. To set theme Go to Android studio -> File -> Import Settings -> Choose the .jar file downloaded.

I faced the same issue. I had missed the forms module import tag in the app.module.ts

import { FormsModule } from '@angular/forms';

@NgModule({
    imports: [BrowserModule,
        FormsModule
    ],

If you want to log inside JSX you can create a dummy component
which plugs where you wish to log:

const Console = prop => (
  console[Object.keys(prop)[0]](...Object.values(prop))
  ,null // ? React components must return something 
)

// Some component with JSX and a logger inside
const App = () => 
  <div>
    <p>imagine this is some component</p>
    <Console log='foo' />
    <p>imagine another component</p>
    <Console warn='bar' />
  </div>

// Render 
ReactDOM.render(
  <App />,
  document.getElementById("react")
)

In operating systems like Ubuntu python comes preinstalled. So the default version is python 2.7 you can confirm the version by typing below command in your terminal

python -V

if you installed it but didn't set default version you will see

python 2.7

in terminal. I will tell you how to set the default python version in Ubuntu.

A simple safe way would be to use an alias. Place this into ~/.bashrc or ~/.bash_aliases file:

alias python=python3

After adding the above in the file, run the command below:

source ~/.bash_aliases or source ~/.bashrc

now check python version again using python -V

if python version 3.x.x one, then the error is in your syntax like using print with parenthesis. change it to

test = input("enter the test")
print(test)

     </div>

     <div class="form-group">
        <button type="submit" class="btn btn-primary col-xs-12">Add</button>
     </div>
  </form>

My Action Is

        [HttpPost]
        public IActionResult AddNews(IFormFile image)
        {
            Tbl_News tbl_News = new Tbl_News();
            if (image!=null)
            {

                //Set Key Name
                string ImageName= Guid.NewGuid().ToString() + Path.GetExtension(image.FileName);

                //Get url To Save
                string SavePath = Path.Combine(Directory.GetCurrentDirectory(),"wwwroot/img",ImageName);

                using(var stream=new FileStream(SavePath, FileMode.Create))
                {
                    image.CopyTo(stream);
                }
            }
            return View();
        }

By using git-add with '--all' or '--update' options you may get more than you wanted. New and/or modified files will also be added to the index. I have a bash alias setup for when I want to remove deleted files from git without touching other files:

alias grma='git ls-files --deleted -z | xargs -0 git rm'

All files that have been removed from the file system are added to the index as deleted.

dancavallaro has it right, %* for all command line parameters (excluding the script name itself). You might also find these useful:

%0 - the command used to call the batch file (could be foo, ..\foo, c:\bats\foo.bat, etc.)
%1 is the first command line parameter,
%2 is the second command line parameter,
and so on till %9 (and SHIFT can be used for those after the 9th).

%~nx0 - the actual name of the batch file, regardless of calling method (some-batch.bat)
%~dp0 - drive and path to the script (d:\scripts)
%~dpnx0 - is the fully qualified path name of the script (d:\scripts\some-batch.bat)

More info examples at https://www.ss64.com/nt/syntax-args.html and https://www.robvanderwoude.com/parameters.html

Or use good old "find". For example in order to look for old mysql v5.7:

cd /
find . type -d -name "[email protected]"

I don't see where you're adding the new column, but try this:

    import csv
    i = 0
    Berry = open("newcolumn.csv","r").readlines()
    with open(input.csv,'r') as csvinput:
        with open(output.csv, 'w') as csvoutput:
            writer = csv.writer(csvoutput)
            for row in csv.reader(csvinput):
                writer.writerow(row+","+Berry[i])
                i++

You just need to escape the quote in your first example:

$ sed 's/\"//g' file.txt

string input = "America.USA"
string output = input.Substring(input.IndexOf('.') + 1);

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

In my project I use this function for getting huge amount of files. It's pretty fast (put require("FS") out to make it even faster):

var _getAllFilesFromFolder = function(dir) {

    var filesystem = require("fs");
    var results = [];

    filesystem.readdirSync(dir).forEach(function(file) {

        file = dir+'/'+file;
        var stat = filesystem.statSync(file);

        if (stat && stat.isDirectory()) {
            results = results.concat(_getAllFilesFromFolder(file))
        } else results.push(file);

    });

    return results;

};

usage is clear:

_getAllFilesFromFolder(__dirname + "folder");

Do the following, download SQLLite Database Browser from here:

Locate your db. file in your phone.

Then, as soon you install the program go to: "Browse Data", you will see all the SMS there!!

You can actually export the data to an excel file or SQL.

Note however:

If you issue SET TRANSACTION ISOLATION LEVEL in a stored procedure or trigger, when the object returns control the isolation level is reset to the level in effect when the object was invoked. For example, if you set REPEATABLE READ in a batch, and the batch then calls a stored procedure that sets the isolation level to SERIALIZABLE, the isolation level setting reverts to REPEATABLE READ when the stored procedure returns control to the batch.

You cannot add a new property() to an instance at runtime, because properties are data descriptors. Instead you must dynamically create a new class, or overload __getattribute__ in order to process data descriptors on instances.

Reading Hadley and Arun's answers one gets the impression that those who prefer dplyr's syntax would have in some cases to switch over to data.table or compromise for long running times.

But as some have already mentioned, dplyr can use data.table as a backend. This is accomplished using the dtplyr package which recently had it's version 1.0.0 release. Learning dtplyr incurs practically zero additional effort.

When using dtplyr one uses the function lazy_dt() to declare a lazy data.table, after which standard dplyr syntax is used to specify operations on it. This would look something like the following:

new_table <- mtcars2 %>% 
  lazy_dt() %>%
  filter(wt < 5) %>% 
  mutate(l100k = 235.21 / mpg) %>% # liters / 100 km
  group_by(cyl) %>% 
  summarise(l100k = mean(l100k))

  new_table

#> Source: local data table [?? x 2]
#> Call:   `_DT1`[wt < 5][, `:=`(l100k = 235.21/mpg)][, .(l100k = mean(l100k)), 
#>     keyby = .(cyl)]
#> 
#>     cyl l100k
#>   <dbl> <dbl>
#> 1     4  9.05
#> 2     6 12.0 
#> 3     8 14.9 
#> 
#> # Use as.data.table()/as.data.frame()/as_tibble() to access results

The new_table object is not evaluated until calling on it as.data.table()/as.data.frame()/as_tibble() at which point the underlying data.table operation is executed.

I've recreated a benchmark analysis done by data.table author Matt Dowle back at December 2018 which covers the case of operations over large numbers of groups. I've found that dtplyr indeed enables for the most part those who prefer the dplyr syntax to keep using it while enjoying the speed offered by data.table.

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

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

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

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

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

GRANT USAGE ON ALL SEQUENCES IN SCHEMA foo TO mygrp;

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

What about new objects?

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

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

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

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

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

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

Just to expand niko's answer:

You can reference any image via its URL. No matter where it is, as long as it's accesible you can use it as the src. Example:

Relative location:

<img src="images/image.png">

The image is sought relative to the document's location. If your document is at http://example.com/site/document.html, then your images folder should be on the same directory where your document.html file is.

Absolute location:

<img src="/site/images/image.png">
<img src="http://example.com/site/images/image.png">

or

<img src="http://another-example.com/images/image.png">

In this case, your image will be sought from the document site's root, so, if your document.html is at http://example.com/site/document.html, the root would be at http://example.com/ (or it's respective directory on the server's filesystem, commonly www/). The first two examples are the same, since both point to the same host, Think of the first / as an alias for your server's root. In the second case, the image is located in another host, so you'd have to specify the complete URL of the image.

Regarding /, . and ..:

The / symbol will always return the root of a filesystem or site.

The single point ./ points to the same directory where you are.

And the double point ../ will point to the upper directory, or the one that contains the actual working directory.

So you can build relative routes using them.

Examples given the route http://example.com/dir/one/two/three/ and your calling document being inside three/:

"./pictures/image.png"

or just

"pictures/image.png"

Will try to find a directory named pictures inside http://example.com/dir/one/two/three/.

"../pictures/image.png"

Will try to find a directory named pictures inside http://example.com/dir/one/two/.

"/pictures/image.png"

Will try to find a directory named pictures directly at / or example.com (which are the same), on the same level as directory.

Create a path with moveTo and lineTo (live demo):

var ctx = canvas.getContext('2d');
ctx.fillStyle = '#f00';
ctx.beginPath();
ctx.moveTo(0, 0);
ctx.lineTo(100,50);
ctx.lineTo(50, 100);
ctx.lineTo(0, 90);
ctx.closePath();
ctx.fill();

RealVNC 5.0.x now offers a VNCViewer that will do dual displays on Windows without having to buy a license. (Licensing now covers the SERVER portion of their tools).

I mostly use following code to scroll down

$('html, body').animate({ scrollTop:  $(SELECTOR).offset().top - 50 }, 'slow');

<select id="test" name="form_select" onchange="showDiv()">
   <option value="0">No</option>
   <option value ="1">Yes</option>
</select>
<div id="hidden_div" style="display: none;">Hello hidden content</div>
<script>
    function showDiv(){
        getSelectValue = document.getElementById("test").value;
        if(getSelectValue == "1"){
            document.getElementById("hidden_div").style.display="block";
        }else{
            document.getElementById("hidden_div").style.display="none";
        }
    }
</script>

package main
import "fmt"
func main() {
  var x float64 = 5.7
  var y int = int(x)
  fmt.Println(y)  // outputs "5"
}

The erase method will be used in two ways:

1. Erasing single element:

   vector.erase( vector.begin() + 3 ); // Deleting the fourth element
   

2. Erasing range of elements:

   vector.erase( vector.begin() + 3, vector.begin() + 5 ); // Deleting from fourth element to sixth element
   

My problem were different indices, the following code solved my problem.

df1.reset_index(drop=True, inplace=True)
df2.reset_index(drop=True, inplace=True)
df = pd.concat([df1, df2], axis=1)

You can also use Date.now() function.

If you are splitting a string in Lua, you should try the string.gmatch() or string.sub() methods. Use the string.sub() method if you know the index you wish to split the string at, or use the string.gmatch() if you will parse the string to find the location to split the string at.

Example using string.gmatch() from Lua 5.1 Reference Manual:

 t = {}
 s = "from=world, to=Lua"
 for k, v in string.gmatch(s, "(%w+)=(%w+)") do
   t[k] = v
 end

With modern Git versions, the command to use would be:

git push -u origin <branch_name_test>

This will automatically set the branch name to track from remote and push in one go.

Well, two ways come to mind and it depends on your preference:

1. Sort the array by characters. Then, counting each character becomes trivial. But you will have to make a copy of the array first.

2. Create another integer array of size 26 (say freq) and str is the array of characters.

   for(int i = 0; i < str.length; i ++)

   freq[str[i] - 'a'] ++; //Assuming all characters are in lower case

So the number of 'a' 's will be stored at freq[0] and the number of 'z' 's will be at freq[25]

Please check whether you are inside your project folder or not and try the command ng serve again

I got the same error since I tried ng serve command outside of my project

Example :: let's say you have a project with name "Ecommerce" traverse into the folder and try the command ng serve open terminal cd Ecommerce ng serve

You seem to be misunderstanding how import searches for modules. When you use an import statement it always searches the actual module path (and/or sys.modules); it doesn't make use of module objects in the local namespace that exist because of previous imports. When you do:

import package.subpackage.module
from package.subpackage import module
from module import attribute1

The second line looks for a package called package.subpackage and imports module from that package. This line has no effect on the third line. The third line just looks for a module called module and doesn't find one. It doesn't "re-use" the object called module that you got from the line above.

In other words from someModule import ... doesn't mean "from the module called someModule that I imported earlier..." it means "from the module named someModule that you find on sys.path...". There is no way to "incrementally" build up a module's path by importing the packages that lead to it. You always have to refer to the entire module name when importing.

It's not clear what you're trying to achieve. If you only want to import the particular object attribute1, just do from package.subpackage.module import attribute1 and be done with it. You need never worry about the long package.subpackage.module once you've imported the name you want from it.

If you do want to have access to the module to access other names later, then you can do from package.subpackage import module and, as you've seen you can then do module.attribute1 and so on as much as you like.

If you want both --- that is, if you want attribute1 directly accessible and you want module accessible, just do both of the above:

from package.subpackage import module
from package.subpackage.module import attribute1
attribute1 # works
module.someOtherAttribute # also works

If you don't like typing package.subpackage even twice, you can just manually create a local reference to attribute1:

from package.subpackage import module
attribute1 = module.attribute1
attribute1 # works
module.someOtherAttribute #also works

If you are using @Configuation then instantiate below static bean. If not static @Configutation is instantiated very early and and the BeanPostProcessors responsible for resolving annotations like @Value, @Autowired etc, cannot act on it. Refer here

@Bean
public static PropertySourcesPlaceholderConfigurer propertyConfigurer() {
   return new PropertySourcesPlaceholderConfigurer();
}

 string filePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
 string extension = ".log";
 filePath += @"\Error Log\" + extension;
 if (!Directory.Exists(filePath))
 {
      Directory.CreateDirectory(filePath);
 }

Try:

Bitmap yourBitmap;
Bitmap resized = Bitmap.createScaledBitmap(yourBitmap, newWidth, newHeight, true);

or:

resized = Bitmap.createScaledBitmap(yourBitmap,(int)(yourBitmap.getWidth()*0.8), (int)(yourBitmap.getHeight()*0.8), true);

I use this code to format floats. It is based on toPrecision() but it strips unnecessary zeros. I would welcome suggestions for how to simplify the regex.

function round(x, n) {
    var exp = Math.pow(10, n);
    return Math.floor(x*exp + 0.5)/exp;
}

Usage example:

function test(x, n, d) {
    var rounded = rnd(x, d);
    var result = rounded.toPrecision(n);
    result = result.replace(/\.?0*$/, '');
    result = result.replace(/\.?0*e/, 'e');
    result = result.replace('e+', 'e');
    return result;  
}

document.write(test(1.2000e45, 3, 2) + '=' + '1.2e45' + '<br>');
document.write(test(1.2000e+45, 3, 2) + '=' + '1.2e45' + '<br>');
document.write(test(1.2340e45, 3, 2) + '=' + '1.23e45' + '<br>');
document.write(test(1.2350e45, 3, 2) + '=' + '1.24e45' + '<br>');
document.write(test(1.0000, 3, 2) + '=' + '1' + '<br>');
document.write(test(1.0100, 3, 2) + '=' + '1.01' + '<br>');
document.write(test(1.2340, 4, 2) + '=' + '1.23' + '<br>');
document.write(test(1.2350, 4, 2) + '=' + '1.24' + '<br>');

As an aside, if you have the pid of the container and want to get the docker id of that container, a good way is to use nsenter in combination with the sed magic above:

nsenter -n -m -t pid -- cat /proc/1/cgroup | grep -o -e "docker-.*.scope" | head -n 1 | sed "s/docker-\(.*\).scope/\\1/"

1. In Notepad++ go to Plugins > Plugin manager > Show Plugin Manager then find Xml Tools plugin. Tick the box and click Install

   

2. Open XML document you want to validate and click Ctrl+Shift+Alt+M (Or use Menu if this is your preference Plugins > XML Tools > Validate Now).
   Following dialog will open:

3. Click on .... Point to XSD file and I am pretty sure you'll be able to handle things from here.

Hope this saves you some time.

EDIT: Plugin manager was not included in some versions of Notepad++ because many users didn't like commercials that it used to show. If you want to keep an older version, however still want plugin manager, you can get it on github, and install it by extracting the archive and copying contents to plugins and updates folder.
In version 7.7.1 plugin manager is back under a different guise... Plugin Admin so now you can simply update notepad++ and have it back.

I suggest you to edit your .vimrc file, for running a list of commands. Edit your .vimrc file, like this :

cat >> ~/.vimrc <<EOF
set ffs=unix
set encoding=utf-8
set fileencoding=utf-8
set listchars=eol:¶
set list
EOF

When you're executing vim, the commands into .vimrc are executed, and you can see this example :

My line with CRLF eol here ^M¶

PCDATA – parsed character data. It parses all the data in an XML document.

Example:

<family>
    <mother>mom</mother>
    <father>dad</father>
</family>

Here, the <family> element contains 2 more elements: <mother> and <father>. So it parses further to get the text of mother and father to give the text value of family as “mom dad”

CDATA – unparsed character Data. This is the data that should not be parsed further in an xml document.

<family>
    <![CDATA[ 
       <mother>mom</mother>
       <father>dad</father>
    ]]>
</family>

Here, the text value of family will be <mother>mom</mother><father>dad</father>.

In Kotlin:

myButton.setOnClickListener { doSomething((it as Button).text) }

Note: This gets the button text as a CharSequence, which more places in code can likely use. If you really want a String from there, then you can use .toString().

For anyone looking for a solution that doesn't require [Serializable] classes and where the result is an approximation instead of exact science. The best method I could find is json serialization into a memorystream using UTF32 encoding.

private static long? GetSizeOfObjectInBytes(object item)
{
    if (item == null) return 0;
    try
    {
        // hackish solution to get an approximation of the size
        var jsonSerializerSettings = new JsonSerializerSettings
        {
            DateFormatHandling = DateFormatHandling.IsoDateFormat,
            DateTimeZoneHandling = DateTimeZoneHandling.Utc,
            MaxDepth = 10,
            ReferenceLoopHandling = ReferenceLoopHandling.Ignore
        };
        var formatter = new JsonMediaTypeFormatter { SerializerSettings = jsonSerializerSettings };
        using (var stream = new MemoryStream()) { 
            formatter.WriteToStream(item.GetType(), item, stream, Encoding.UTF32);
            return stream.Length / 4; // 32 bits per character = 4 bytes per character
        }
    }
    catch (Exception)
    {
        return null;
    }
}

No, this won't give you the exact size that would be used in memory. As previously mentioned, that is not possible. But it'll give you a rough estimation.

Note that this is also pretty slow.

You can add new function to your jQuery library by adding these line on your own script file and you can easily use fadeSlideRight() and fadeSlideLeft().

Note: you can change width of animation as you like instance of 750px.

$.fn.fadeSlideRight = function(speed,fn) {
    return $(this).animate({
        'opacity' : 1,
        'width' : '750px'
    },speed || 400, function() {
        $.isFunction(fn) && fn.call(this);
    });
}

$.fn.fadeSlideLeft = function(speed,fn) {
    return $(this).animate({
        'opacity' : 0,
        'width' : '0px'
    },speed || 400,function() {
        $.isFunction(fn) && fn.call(this);
    });
}

The most efficient way would be to always use []byte instead of string.

In case you need to print data received from the io.ReadCloser, the fmt package can handle []byte, but it isn't efficient because the fmt implementation will internally convert []byte to string. In order to avoid this conversion, you can implement the fmt.Formatter interface for a type like type ByteSlice []byte.

import numpy as np

n = 51 #number of data points
# Suppose the real and imaginary parts are created independently
real_part = np.random.normal(size=n)
imag_part = np.random.normal(size=n)

# Create a complex array - the imaginary part will be equal to zero
z = np.array(real_part, dtype=complex)
# Now define the imaginary part:
z.imag = imag_part
print(z)

Reader reader = new BufferedReader(
    new InputStreamReader(
        new ByteArrayInputStream(
            string.getBytes(StandardCharsets.UTF_8)), StandardCharsets.UTF_8));

You forgot the HTTP part:

window.location.href = "http://example.com/Registration/Success/";

The script below is a generic solution that works for me. It is based on ideas pulled from this and other threads.

When a link with an href attribute beginning with "#" is clicked, it scrolls the page smoothly to the indicated div. Where only the "#" is present, it scrolls smoothly to the top of the page.

$('a[href^=#]').click(function(){
    event.preventDefault();
    var target = $(this).attr('href');
    if (target == '#')
      $('html, body').animate({scrollTop : 0}, 600);
    else
      $('html, body').animate({
        scrollTop: $(target).offset().top - 100
    }, 600);
});

For example, When the code above is present, clicking a link with the tag <a href="#"> scrolls to the top of the page at speed 600. Clicking a link with the tag <a href="#mydiv"> scrolls to 100px above <div id="mydiv"> at speed 600. Feel free to change these numbers.

I hope it helps!

You are having a very common closure problem in the for in loop:

Variables enclosed in a closure share the same single environment, so by the time the click callback from the addListener is called, the loop will have run its course and the info variable will be left pointing to the last object, which happens to be the last InfoWindow created.

In this case, one easy way to solve this problem would be to augment your Marker object with the InfoWindow:

var marker = new google.maps.Marker({map: map, position: point, clickable: true});

marker.info = new google.maps.InfoWindow({
  content: '<b>Speed:</b> ' + values.inst + ' knots'
});

google.maps.event.addListener(marker, 'click', function() {
  marker.info.open(map, marker);
});

This can be quite a tricky topic, if you are not familiar with how closures work. You may to check out the following Mozilla article for a brief introduction:

• Working with Closures

Also keep in mind, that the v3 API allows multiple InfoWindows on the map. If you intend to have just one InfoWindow visible at the time, you should instead use a single InfoWindow object, and then open it and change its content whenever the marker is clicked (Source).

Go to Jenkins -> Manage Jenkins -> Configure System -> Global properties Check the box 'Environment variables' and add the JAVA_HOME path = "C:\Program Files\Java\jdk-10.0.1"

*Don't write bin at the end

My guess is that the system-status element is declared after the variable declaration is run. Thus, at the time the variable is declared, it is actually being set to null?

You should declare it only, then assign its value from an onLoad handler instead, because then you will be sure that it has properly initialized (loaded) the element in question.

You could also try putting the script at the bottom of the page (or at least somewhere after the system-status element is declared) but it's not guaranteed to always work.

Try this out:-

http://jsfiddle.net/adiioo7/vmfbA/

Use

document.body.innerHTML += '<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>';

instead of

document.body.innerHTML = '<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>';

Edit:- Ideally you should use body.appendChild method instead of changing the innerHTML

var elem = document.createElement('div');
elem.style.cssText = 'position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000';
document.body.appendChild(elem);

A source of confusion may be the use of the word in two different contexts - data modelling and database query optimization.

In data modelling terms, cardinality is how one table relates to another.

• 1-1 (one row in table A relates to one row in tableB)
• 1-Many (one row in table A relates to many rows in tableB)
• Many-Many (Many rows in table A relate to many rows in tableB)

There are also optional participation conditions to the above (where a row in one table doesn't have to relate to the other table at all).

See Wikipedia on Cardinality (data modelling).

When talking about database query optimization, cardinality refers to the data in a column of a table, specifically how many unique values are in it. This statistic helps with planning queries and optimizing the execution plans.

See Wikipedia on Cardinality (SQL statements).

Simply attr-accessor creates the getter and setter methods for the specified attributes

you can also use this code in your style.xml file so you don't need to write anything else in your activity.java

Currently you are clearing the name array, you need to call the array then the index you want to unset within the array:

$ar[0]==2
$ar[1]==7
$ar[2]==9

unset ($ar[2])

Two ways of unsetting values within an array:

<?php
# remove by key:
function array_remove_key ()
{
  $args  = func_get_args();
  return array_diff_key($args[0],array_flip(array_slice($args,1)));
}
# remove by value:
function array_remove_value ()
{
  $args = func_get_args();
  return array_diff($args[0],array_slice($args,1));
}

$fruit_inventory = array(
  'apples' => 52,
  'bananas' => 78,
  'peaches' => 'out of season',
  'pears' => 'out of season',
  'oranges' => 'no longer sold',
  'carrots' => 15,
  'beets' => 15,
);

echo "<pre>Original Array:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';

# For example, beets and carrots are not fruits...
$fruit_inventory = array_remove_key($fruit_inventory,
                                    "beets",
                                    "carrots");
echo "<pre>Array after key removal:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';

# Let's also remove 'out of season' and 'no longer sold' fruit...
$fruit_inventory = array_remove_value($fruit_inventory,
                                      "out of season",
                                      "no longer sold");
echo "<pre>Array after value removal:\n",
     print_r($fruit_inventory,TRUE),
     '</pre>';
?> 

So, unset has no effect to internal array counter!!!

Pure Bash, use parameter substitution:

This link explains where you're going wrong:

[35.12] Why can't I separate the definition of my templates class from its declaration and put it inside a .cpp file?

Place the definition of your constructors, destructors methods and whatnot in your header file, and that will correct the problem.

This offers another solution:

How can I avoid linker errors with my template functions?

However this requires you to anticipate how your template will be used and, as a general solution, is counter-intuitive. It does solve the corner case though where you develop a template to be used by some internal mechanism, and you want to police the manner in which it is used.

You have to log the responseText:

$.ajax({
    type: 'POST',
    url: 'status.ajax.php',
    data: {
    deviceId: id
  }
})
.done(
 function (data) {
  //your code
 }
)
.fail(function (data) {
      console.log( "Ajax failed: " + data['responseText'] );
})

You need to add else in your lambda function. Because you are telling what to do in case your condition(here x < 90) is met, but you are not telling what to do in case the condition is not met.

sample['PR'] = sample['PR'].apply(lambda x: 'NaN' if x < 90 else x) 

The typical command is:

docker container ls -f 'status=exited'

However, this will only list one of the possible non-running statuses. Here's a list of all possible statuses:

• created
• restarting
• running
• removing
• paused
• exited
• dead

You can filter on multiple statuses by passing multiple filters on the status:

docker container ls -f 'status=exited' -f 'status=dead' -f 'status=created'

If you are integrating this with an automatic cleanup script, you can chain one command to another with some bash syntax, output just the container id's with -q, and you can also limit to just the containers that exited successfully with an exit code filter:

docker container rm $(docker container ls -q -f 'status=exited' -f 'exited=0')

For more details on filters you can use, see Docker's documentation: https://docs.docker.com/engine/reference/commandline/ps/#filtering

Simple way that works and I checked.

private readonly UserManager<IdentityUser> _userManager;
public CompetitionsController(UserManager<IdentityUser> userManager)
{
    _userManager = userManager;
}

var user = await _userManager.GetUserAsync(HttpContext.User);

then you can all the properties of this variables like user.Email. I hope this would help someone.

Edit:

It's an apparently simple thing but bit complicated cause of different types of authentication systems in ASP.NET Core. I update cause some people are getting null.

For JWT Authentication (Tested on ASP.NET Core v3.0.0-preview7):

var email = HttpContext.User.Claims.FirstOrDefault(c => c.Type == "sub")?.Value;

var user = await _userManager.FindByEmailAsync(email);

To change it permanently in Windows (10), edit the my.ini file. To find the my.ini file, look at the path in the Windows server. E.g. for my MySQL 5.7 instance, the service is MYSQL57, and in this service's properties the Path to executable is:

"C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqld.exe" --defaults-file="C:\ProgramData\MySQL\MySQL Server 5.7\my.ini" MySQL57

I.e. edit the my.ini file in C:\ProgramData\MySQL\MySQL Server 5.7\. Note that C:\ProgramData\ is a hidden folder in Windows (10). My file has the following lines of interest:

# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Remove STRICT_TRANS_TABLES, from this sql-mode line, save the file and restart the MYSQL57 service. Verify the result by executing SHOW VARIABLES LIKE 'sql_mode'; in a (new) MySQL Command Line Client window.

(I found the other answers and documents on the web useful, but none of them seem to tell you where to find the my.ini file in Windows.)

Yes;

git commit FILE

will commit just FILE. Then you can use

git reset --hard

to undo local changes in other files.

There may be other ways too that I don't know about...

edit: or, as NicDumZ said, git-checkout just the files you want to undo the changes on (the best solution depends on wether there are more files to commit or more files to undo :-)

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

This is the shortest way you can do that

list.push($('<li>', {text: blocks[i] }));
$('ul').append(list);

Where blocks in an array. and you need to loop through the array.

2D scatter plot

Using the scatter method of the matplotlib.pyplot module should work (at least with matplotlib 1.2.1 with Python 2.7.5), as in the example code below. Also, if you are using scatter plots, use scatterpoints=1 rather than numpoints=1 in the legend call to have only one point for each legend entry.

In the code below I've used random values rather than plotting the same range over and over, making all the plots visible (i.e. not overlapping each other).

import matplotlib.pyplot as plt
from numpy.random import random

colors = ['b', 'c', 'y', 'm', 'r']

lo = plt.scatter(random(10), random(10), marker='x', color=colors[0])
ll = plt.scatter(random(10), random(10), marker='o', color=colors[0])
l  = plt.scatter(random(10), random(10), marker='o', color=colors[1])
a  = plt.scatter(random(10), random(10), marker='o', color=colors[2])
h  = plt.scatter(random(10), random(10), marker='o', color=colors[3])
hh = plt.scatter(random(10), random(10), marker='o', color=colors[4])
ho = plt.scatter(random(10), random(10), marker='x', color=colors[4])

plt.legend((lo, ll, l, a, h, hh, ho),
           ('Low Outlier', 'LoLo', 'Lo', 'Average', 'Hi', 'HiHi', 'High Outlier'),
           scatterpoints=1,
           loc='lower left',
           ncol=3,
           fontsize=8)

plt.show()

3D scatter plot

To plot a scatter in 3D, use the plot method, as the legend does not support Patch3DCollection as is returned by the scatter method of an Axes3D instance. To specify the markerstyle you can include this as a positional argument in the method call, as seen in the example below. Optionally one can include argument to both the linestyle and marker parameters.

import matplotlib.pyplot as plt
from numpy.random import random
from mpl_toolkits.mplot3d import Axes3D

colors=['b', 'c', 'y', 'm', 'r']

ax = plt.subplot(111, projection='3d')

ax.plot(random(10), random(10), random(10), 'x', color=colors[0], label='Low Outlier')
ax.plot(random(10), random(10), random(10), 'o', color=colors[0], label='LoLo')
ax.plot(random(10), random(10), random(10), 'o', color=colors[1], label='Lo')
ax.plot(random(10), random(10), random(10), 'o', color=colors[2], label='Average')
ax.plot(random(10), random(10), random(10), 'o', color=colors[3], label='Hi')
ax.plot(random(10), random(10), random(10), 'o', color=colors[4], label='HiHi')
ax.plot(random(10), random(10), random(10), 'x', color=colors[4], label='High Outlier')

plt.legend(loc='upper left', numpoints=1, ncol=3, fontsize=8, bbox_to_anchor=(0, 0))

plt.show()

Explicitly creating an out folder and then setting the output path to C:\Users\USERNAME\IdeaProjects\PROJECTNAME\out

seemed to work for me when just out, and expecting IntelliJ to make the folder wouldn't.

Also try having IntelliJ make you a new run configuration:

Find the previous one by clicking

then remove it

and hit okay.

Now, (IMPORTANT STEP) open the class containing your main method. This is probably easiest done by clicking on the class name in the left-hand side Project Pane.

Give 'er a Alt + Shift + F10 and you should get a

Now hit Enter!!

Tadah?? (Did it work?)

Based on Kalaxy's response, the following is a templated solution that rounds any floating point number to the nearest integer type based on natural rounding. It also throws an error in debug mode if the value is out of range of the integer type, thereby serving roughly as a viable library function.

    // round a floating point number to the nearest integer
    template <typename Arg>
    int Round(Arg arg)
    {
#ifndef NDEBUG
        // check that the argument can be rounded given the return type:
        if (
            (Arg)std::numeric_limits<int>::max() < arg + (Arg) 0.5) ||
            (Arg)std::numeric_limits<int>::lowest() > arg - (Arg) 0.5)
            )
        {
            throw std::overflow_error("out of bounds");
        }
#endif

        return (arg > (Arg) 0.0) ? (int)(r + (Arg) 0.5) : (int)(r - (Arg) 0.5);
    }

You can use .contents:

>>> for hit in soup.findAll(attrs={'class' : 'MYCLASS'}):
...     print hit.contents[6].strip()
... 
THIS IS MY TEXT

I solve it like that. Use bootstrap 4

    $(document).ready(function () {
        $('#table').DataTable({
            "searching": false,
            "paging": false,
            "info": false
        });
    });

My scope consists of template download and verifies the template when it's filled with data So,

1) Download a template (.xlsx) file with the header row. the file is generated using openxml and it's working perfectly.

2) Upload the same file without any change from it's downloaded state. This will cause a connection error and fails (OLEDB connection is using for reading the excel sheet).

Here if the data is filled the program works as expected.

Anybody having an idea the issue is connected with the file we are creating it's in xml format if we open it and just save convert it in to excel format and it works well.

Any idea to download the excel with the preferred file type?

Note: From Graph API v8.0 you must provide the access token for every UserID request you do.

Hitting the graph API:

https://graph.facebook.com/<user_id>/picture?height=1000&access_token=<any_of_above_token>

With firebase:

FirebaseUser user = mAuth.getCurrentUser();
String photoUrl = user.getPhotoUrl() + "/picture?height=1000&access_token=" +
  loginResult.getAccessToken().getToken();

You get the token from registerCallback just like this

       LoginManager.getInstance().registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            FirebaseUser user = mAuth.getCurrentUser();
            String photoUrl = user.getPhotoUrl() + "/picture?height=1000&access_token=" + loginResult.getAccessToken().getToken();
        }

        @Override
        public void onCancel() {
            Log.d("Fb on Login", "facebook:onCancel");
        }

        @Override
        public void onError(FacebookException error) {
            Log.e("Fb on Login", "facebook:onError", error);
        }
    });

This is what documentation says:

Beginning October 24, 2020, an access token will be required for all UID-based queries. If you query a UID and thus must include a token:

• use a User access token for Facebook Login authenticated requests
• use a Page access token for page-scoped requests
• use an App access token for server-side requests
• use a Client access token for mobile or web client-side requests

We recommend that you only use a Client token if you are unable to use one of the other token types.

If you just want to echo a message from PHP in a certain place on the page when the user clicks the button, you could do something like this:

<button type="button" id="okButton" onclick="funk()" value="okButton">Order now</button>
<div id="resultMsg"></div>
<script type="text/javascript">
function funk(){
  alert("asdasd");
  document.getElementById('resultMsg').innerHTML('<?php echo "asdasda";?>');
}
</script>

However, assuming your script needs to do some server-side processing such as adding the item to a cart, you may like to check out jQuery's http://api.jquery.com/load/ - use jQuery to load the path to the php script which does the processing. In your example you could do:

<button type="button" id="okButton" onclick="funk()" value="okButton">Order now</button>
<div id="resultMsg"></div>
<script type="text/javascript">
function funk(){
  alert("asdasd");
  $('#resultMsg').load('path/to/php/script/order_item.php');
}
</script>

This runs the php script and loads whatever message it returns into <div id="resultMsg">.

order_item.php would add the item to cart and just echo whatever message you would like displayed. To get the example working this will suffice as order_item.php:

<?php
// do adding to cart stuff here
echo 'Added to cart';
?>

For this to work you will need to include jQuery on your page, by adding this in your <head> tag:

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>

I know this is an old post, but i was having a problem like the OP and this is what i came up with.

Example of array you could pass. You could re order this if a particular order was required, but for this question this will do what is asked.

$argument_set = array (8 => 'lots', 5 => 'of', 1 => 'data', 2 => 'here');

This is manageable, easy to read and the data extraction points can be added and removed at a moments notice anywhere in coding and still avoid a massive rewrite. I used integer keys to tally with the OP original question but string keys could be used just as easily. In fact for readability I would advise it.

Stick this in an external file for ease

function unknown_number_arguments($argument_set) {

    foreach ($argument_set as $key => $value) {

        # create a switch with all the cases you need. as you loop the array 
        # keys only your submitted $keys values will be found with the switch. 
        switch ($key) {
            case 1:
                # do stuff with $value
                break;
            case 2:
                # do stuff with $value;
                break;
            case 3:
                # key 3 omitted, this wont execute 
                break;
            case 5:
                # do stuff with $value;
                break;
            case 8:
                # do stuff with $value;
                break;
            default:
                # no match from the array, do error logging?
                break;
        }
    }
return;
}

put this at the start if the file.

$argument_set = array(); 

Just use these to assign the next piece of data use numbering/naming according to where the data is coming from.

$argument_set[1][] = $some_variable; 

And finally pass the array

unknown_number_arguments($argument_set);

The two queries may not be semantically equivalent. If a employee works for more than one department (possible in the enterprise I work for; admittedly, this would imply your table is not fully normalized) then the first query would return duplicate rows whereas the second query would not. To make the queries equivalent in this case, the DISTINCT keyword would have to be added to the SELECT clause, which may have an impact on performance.

Note there is a design rule of thumb that states a table should model an entity/class or a relationship between entities/classes but not both. Therefore, I suggest you create a third table, say OrgChart, to model the relationship between employees and departments.

Taking a combination of @sawa's answer and the comment listed there you could implement a "quick" index and rindex on the array class.

class Array
  def quick_index el
    hash = Hash[self.map.with_index.to_a]
    hash[el]
  end

  def quick_rindex el
    hash = Hash[self.reverse.map.with_index.to_a]
    array.length - 1 - hash[el]
  end
end

This is a known bug. flexWrap: 'wrap' didn't work for me but this solution seems to work for most people

Code

<View style={styles.container}>
    <Text>Some text</Text>
</View>

Styles

export default StyleSheet.create({
    container: {
        width: 0,
        flexGrow: 1,
        flex: 1,
    }
});

Because ... it (MILLISECONDS) is a static field (hiding in an enumeration, but that's what it is) ... however it is being invoked upon an instance of the given type (but see below as this isn't really true¹).

javac will "accept" that, but it should really be MyUnits.MILLISECONDS (or non-prefixed in the applicable scope).

¹ Actually, javac "rewrites" the code to the preferred form -- if m happened to be null it would not throw an NPE at run-time -- it is never actually invoked upon the instance).

Happy coding.

I'm not really seeing how the question title fits in with the rest :-) More accurate and specialized titles increase the likely hood the question/answers can benefit other programmers.

you can use this trick to run tomcat using cmd and directly by tomcat bin folder.

1. set the path of jdk.

2.

To set path. go to Desktop and right click on computer icon. Click the Properties

go to Advance System Settings.

then Click Advance to Environment variables.

Click new and set path AS,

in the column Variable name=JAVA_HOME

Variable Value=C:\Program Files\Java\jdk1.6.0_19

Click ok ok.

now path is stetted.

3.

Go to tomcat folder where you installed the tomcat. go to bin folder. there are two window batch files.

1.Startup

2.Shutdown.

By using cmd if you installed the tomcate in D Drive

type on cmd screen

1. D:

2. Cd tomcat\bin then type Startup.

4. By clicking them you can start and stop the tomcat.

5.

Final step.

if you start and want to check it.

open a Browser in URL bar type.

I was facing same problem.Tried every think mentioned here in blog.

But it was basic error to permit device "allow installing app from USB" which did it for me.

use:

sleep(NUMBER_OF_SECONDS);

I had the same problem some time ago and was disappointed because I couldn't find any solution that suites my needs so I wrote my own class. Honestly, I did found some code back then, but even that wasn't what I was searching for so I adapted it and now I'm sharing it, just like the author of that piece of code did.

EDIT: This is the original (although slightly different) code: CircularArrayList for java

I don't have the link of the source because it was time ago, but here's the code:

import java.util.AbstractList;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.RandomAccess;

public class CircularArrayList<E> extends AbstractList<E> implements RandomAccess {

private final int n; // buffer length
private final List<E> buf; // a List implementing RandomAccess
private int leader = 0;
private int size = 0;


public CircularArrayList(int capacity) {
    n = capacity + 1;
    buf = new ArrayList<E>(Collections.nCopies(n, (E) null));
}

public int capacity() {
    return n - 1;
}

private int wrapIndex(int i) {
    int m = i % n;
    if (m < 0) { // modulus can be negative
        m += n;
    }
    return m;
}

@Override
public int size() {
    return this.size;
}

@Override
public E get(int i) {
    if (i < 0 || i >= n-1) throw new IndexOutOfBoundsException();

    if(i > size()) throw new NullPointerException("Index is greater than size.");

    return buf.get(wrapIndex(leader + i));
}

@Override
public E set(int i, E e) {
    if (i < 0 || i >= n-1) {
        throw new IndexOutOfBoundsException();
    }
    if(i == size()) // assume leader's position as invalid (should use insert(e))
        throw new IndexOutOfBoundsException("The size of the list is " + size() + " while the index was " + i
                +". Please use insert(e) method to fill the list.");
    return buf.set(wrapIndex(leader - size + i), e);
}

public void insert(E e)
{
    int s = size();     
    buf.set(wrapIndex(leader), e);
    leader = wrapIndex(++leader);
    buf.set(leader, null);
    if(s == n-1)
        return; // we have replaced the eldest element.
    this.size++;

}

@Override
public void clear()
{
    int cnt = wrapIndex(leader-size());
    for(; cnt != leader; cnt = wrapIndex(++cnt))
        this.buf.set(cnt, null);
    this.size = 0;      
}

    int i = wrapIndex(leader+1);

    for(;;i = wrapIndex(++i)) {
        if(buf.get(i) != null) break;
        if(i == leader)
            throw new IllegalStateException("Cannot remove element."
                    + " CircularArrayList is empty.");
    }

    this.size--;
    return buf.set(i, null);
}

@Override
public String toString()
{
    int i = wrapIndex(leader - size());
    StringBuilder str = new StringBuilder(size());

    for(; i != leader; i = wrapIndex(++i)){
        str.append(buf.get(i));
    }
    return str.toString();

The related_name attribute specifies the name of the reverse relation from the User model back to your model.

If you don't specify a related_name, Django automatically creates one using the name of your model with the suffix _set, for instance User.map_set.all().

If you do specify, e.g. related_name=maps on the User model, User.map_set will still work, but the User.maps. syntax is obviously a bit cleaner and less clunky; so for example, if you had a user object current_user, you could use current_user.maps.all() to get all instances of your Map model that have a relation to current_user.

The Django documentation has more details.

You've already done it correctly by using a DateTime parameter with the value from the DateTime, so it should already work. Forget about ToString() - since that isn't used here.

If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).

I have a table and the date-times in it are in the format: 2011-07-01 15:17:33.357

Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.

You don't need jQuery to do this. Embrace the power of JavaScript.

window.location.reload()

Just add the ? sign after index.php in the .htaccess file :

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

and it would work !

You can write a script and then use nohup ./yourscript & to execute

For example:

vi yourscript

put

#!/bin/bash
script here

you may also need to change permission to run script on server

chmod u+rwx yourscript

finally

nohup ./yourscript &

Why not update the files on the local file system instead? You can read/write files into your applications sandboxed area.

Additional to @Daniel Waltrip answer. Table need to enclose with div position: relative in order to work with position:sticky . So I would like to post my sample code here.

CSS

/* Set table width/height as you want.*/
div.freeze-header {
  position: relative;
  max-height: 150px;
  max-width: 400px;
  overflow:auto;
}

/* Use position:sticky to freeze header on top*/
div.freeze-header > table > thead > tr > th {
  position: sticky;
  top: 0;
  background-color:yellow;
}

/* below is just table style decoration.*/
div.freeze-header > table {
  border-collapse: collapse;
}

div.freeze-header > table td {
  border: 1px solid black;
}

Demo

ID % 2 is checking what the remainder is if you divide ID by 2. If you divide an even number by 2 it will always have a remainder of 0. Any other number (odd) will result in a non-zero value. Which is what is checking for.

Handling a browser window using Selenium WebDriver:

String winHandleBefore = driver.getWindowHandle();

for(String winHandle : driver.getWindowHandles())  // Switch to new opened window
{
    driver.switchTo().window(winHandle);
}

driver.switchTo().window(winHandleBefore);   // Move to previously opened window

Using Python to make a flushproject command, you use :

from django.db import connection
cursor = connection.cursor()
cursor.execute(“DROP DATABASE %s;”, [connection.settings_dict['NAME']])
cursor.execute(“CREATE DATABASE %s;”, [connection.settings_dict['NAME']])

You can use this (or any variant):

Files.copy(src, dst, StandardCopyOption.REPLACE_EXISTING);

Also, I'd recommend using File.separator or / instead of \\ to make it compliant across multiple OS, question/answer on this available here.

Since you're not sure how to temporarily store files, take a look at ArrayList:

List<File> files = new ArrayList();
files.add(foundFile);

To move a List of files into a single directory:

List<File> files = ...;
String path = "C:/destination/";
for(File file : files) {
    Files.copy(file.toPath(),
        (new File(path + file.getName())).toPath(),
        StandardCopyOption.REPLACE_EXISTING);
}
