An object is defined by an OBJECT_ID, which is unique. If A and B are objects and A == B is true, then they are the very same object, they have the same data and methods, but, this is also true:

A.OBJECT_ID == B.OBJECT_ID

if A.Equals(B) is true, that means that the two objects are in the same state, but this doesn't mean that A is the very same as B.

Strings are objects.

Note that the == and Equals operators are reflexive, simetric, tranzitive, so they are equivalentic relations (to use relational algebraic terms)

What this means: If A, B and C are objects, then:

(1) A == A is always true; A.Equals(A) is always true (reflexivity)

(2) if A == B then B == A; If A.Equals(B) then B.Equals(A) (simetry)

(3) if A == B and B == C, then A == C; if A.Equals(B) and B.Equals(C) then A.Equals(C) (tranzitivity)

Also, you can note that this is also true:

(A == B) => (A.Equals(B)), but the inverse is not true.

A B =>
0 0 1
0 1 1
1 0 0
1 1 1

Example of real life: Two Hamburgers of the same type have the same properties: they are objects of the Hamburger class, their properties are exactly the same, but they are different entities. If you buy these two Hamburgers and eat one, the other one won't be eaten. So, the difference between Equals and ==: You have hamburger1 and hamburger2. They are exactly in the same state (the same weight, the same temperature, the same taste), so hamburger1.Equals(hamburger2) is true. But hamburger1 == hamburger2 is false, because if the state of hamburger1 changes, the state of hamburger2 not necessarily change and vice versa.

If you and a friend get a Hamburger, which is yours and his in the same time, then you must decide to split the Hamburger into two parts, because you.getHamburger() == friend.getHamburger() is true and if this happens: friend.eatHamburger(), then your Hamburger will be eaten too.

I could write other nuances about Equals and ==, but I'm getting hungry, so I have to go.

I've coded up a simple example for you and annotated the source. The example shows how to grab live json and parse into a JSONObject for detail extraction:

try{
    // Create a new HTTP Client
    DefaultHttpClient defaultClient = new DefaultHttpClient();
    // Setup the get request
    HttpGet httpGetRequest = new HttpGet("http://example.json");

    // Execute the request in the client
    HttpResponse httpResponse = defaultClient.execute(httpGetRequest);
    // Grab the response
    BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(), "UTF-8"));
    String json = reader.readLine();

    // Instantiate a JSON object from the request response
    JSONObject jsonObject = new JSONObject(json);

} catch(Exception e){
    // In your production code handle any errors and catch the individual exceptions
    e.printStackTrace();
}

Once you have your JSONObject refer to the SDK for details on how to extract the data you require.

That should be (see the docs):

cmake -DCMAKE_INSTALL_PREFIX=/usr ..

You can also use this

$scope.persons = $filter('filter')($scope.persons , { id: ('!' + person.id) });

On my mac, the following inserts a single 'n' instead of newline:

sed 's/regexp/\n&/g'

This replaces with newline:

sed "s/regexp/\\`echo -e '\n\r'`/g"

KDiff3 open source, cross platform

Same interface for Linux and Windows, very smart algorithm for solving conflicts, regular expressions for automatically solving conflicts, integrate with ClearCase, SVN, Git, MS Visual Studio, editable merged file, compare directories

Its keyboard-navigation is great: ctrl-arrows to navigate the diffs, ctrl-1, 2, 3 to do the merging.

How to delete a database in phpMyAdmin?

From the Operations tab of the database, look for (and click) the text Drop the database (DROP).

"I've gone with the server approach. Seems to work fine - thanks. – reach4thelasers Dec 1 '09 at 15:19" I would like to recommend it from the owner. As quoted: javascript solution depends on how the server handler (I didn't check it)

such as

if(!isset($_POST["checkbox"]) or empty($_POST["checkbox"])) $_POST["checkbox"]="something";

As you know angular.module( declared under angular.js file.So before accessing angular.module, you must have make it available by using <script src="lib/angular/angular.js"></script>(In your case) after then you can call angular.module. It will work.

like

<html lang="en">
<head>
  <meta charset="utf-8">
  <title>My AngularJS App</title>
  <link rel="stylesheet" href="css/app.css"/>
<!-- In production use:
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
  -->
  <script src="lib/angular/angular.js"></script>
  <script src="lib/angular/angular-route.js"></script>
  <script src="js/app.js"></script>
  <script src="js/services.js"></script>
  <script src="js/controllers.js"></script>
  <script src="js/filters.js"></script>
  <script src="js/directives.js"></script>

    <script>
        var app = angular.module('myApp',[]);

        app.directive('myDirective',function(){

            return function(scope, element,attrs) {
                element.bind('click',function() {alert('click')});
            };

        });
    </script>
</head>
<body ng-app="myApp">
    <div >
        <button my-directive>Click Me!</button>
    </div>
    <h1>{{2+3}}</h1>

</body>

This will set the safemode switch:

bcdedit /set {current} safeboot minimal 

with networking:

bcdedit /set {current} safeboot network

then reboot the machine with

shutdown /r

to put back in normal mode via dos:

bcdedit /deletevalue {current} safeboot

Is it legal? Yes, changing your location on Android is legal. Likewise, you can change VPN settings in Microsoft Edge on your PC, and all this is within the law. VPN allows you to change your IP address, safeguarding your privacy and protecting your actual location from being exposed. However, VPN laws may vary from country to country. There are restrictions in some regions.

Brief summary: Yes, you can change your region on Android and a VPN is a necessary assistant for this. It's simple, safe and legal. Today, VPN is the best way to change the region and unblock sites with regional restrictions.

You can do like this:

private void datagridview1_SelectionChanged(object sender, EventArgs e)
{
  if (datagridview1.SelectedCells.Count > 0)
  {
    int selectedrowindex = datagridview1.SelectedCells[0].RowIndex;
    DataGridViewRow selectedRow = datagridview1.Rows[selectedrowindex];  
    string cellValue = Convert.ToString(selectedRow.Cells["enter column name"].Value);           
  }
}

For posix (Linux, BSD, etc... only need /proc directory to be mounted) it's easier to work with os files in /proc. It's pure python, no need to call shell programs outside.

Works on python 2 and 3 ( The only difference (2to3) is the Exception tree, therefore the "except Exception", which I dislike but kept to maintain compatibility. Also could've created a custom exception.)

#!/usr/bin/env python

import os
import sys


for dirname in os.listdir('/proc'):
    if dirname == 'curproc':
        continue

    try:
        with open('/proc/{}/cmdline'.format(dirname), mode='rb') as fd:
            content = fd.read().decode().split('\x00')
    except Exception:
        continue

    for i in sys.argv[1:]:
        if i in content[0]:
            print('{0:<12} : {1}'.format(dirname, ' '.join(content)))

Sample Output (it works like pgrep):

phoemur ~/python $ ./pgrep.py bash
1487         : -bash 
1779         : /bin/bash

None of these answers solved my problem, which was that the items weren't the same width in my makeshift flexbox table when it was shrunk to a width too small.

The solution for me was simply to put overflow: hidden; on the flex-grow: 1; cells.

Go to the folder where Python is installed, e.g., in my case (Mac OS) it is installed in the Applications folder with the folder name 'Python 3.6'. Now double click on 'Install Certificates.command'. You will no longer face this error.

For those not running a mac, or having a different setup and can't find this file, the file merely runs:

pip install --upgrade certifi

Hope that helps someone :)

There is an option in Postman if you download it from https://www.getpostman.com instead of the chrome store (most probably it has been introduced in the new versions and the chrome one will be updated later) not sure about the old ones.

In the settings, turn off the SSL certificate verification option

Be sure to remember to reactivate it afterwards, this is a security feature.

If you really want to use the chrome app, you could always add an exception to chrome for the url: Enter the url you would like to open in the chrome browser, you'll get a warning with a link at the bottom of the page to add an exception, which if you do, it will also allow postman to access your url. But the first option of using the postman stand-alone app is much better.

I hope this can help.

All you need is a control that you can set the text of, and an UpdatePanel if the exception occurs during a postback.

If occurs during a postback: markup:

<ajax:UpdatePanel id="ErrorUpdatePanel" runat="server" UpdateMode="Coditional">
<ContentTemplate>
<asp:TextBox id="ErrorTextBox" runat="server" />
</ContentTemplate>
</ajax:UpdatePanel>

code:

try
{
do something
}

catch(YourException ex)
{
this.ErrorTextBox.Text = ex.Message;
this.ErrorUpdatePanel.Update();
}

There are a lot of ways to add a border to a textView. The simplest one is by creating a custom drawable and setting it as android:background="@drawable/textview_bg" for your textView.

The textview_bg.xml will go under Drawables and can be something like this. You can have a solid or a gradient background (or nothing if not required), corners to add a corner radius and stroke to add border.

textview_bg.xml

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="rectangle">

        <corners
            android:radius="@dimen/dp_10"/>

        <gradient
            android:angle="225"
            android:endColor="#FFFFFF"
            android:startColor="#E0E0E0" />

        <stroke
            android:width="2dp"
            android:color="#000000"/>

    </shape>

Pure Javascript solution

theId.onclick = () => window.scrollTo({top: 0})

If you want smooth scrolling

theId.onclick = () => window.scrollTo({ top: 0, behavior: `smooth` })

Google doesn't allow test auth api on localhost using http://webporject.dev or .loc and .etc and google short link that shortened your local url(http://webporject.dev) also bit.ly :). Google accepts only url which starts http://localhost/...

if you want to test google auth api you should follow these steps ...

if you use openserver go to settings panel and click on aliases tab and click on dropdown then find localhost and choose it.

now you should choose your local web project root folder by clicking the next dropdown that is next to first dropdown.

and click on a button called add and restart opensever.

now your local project available on this link http://localhost/ also you can paste this local url to google auth api to redirect url field...

To preserve the order:

l = [1, 1, 2, 2, 3]
result = list()
map(lambda x: not x in result and result.append(x), l)
result
# [1, 2, 3]

Try this regex:

/^[a-z\d\-_\s]+$/i

Your makefile should ideally be named makefile, not make. Note that you can call your makefile anything you like, but as you found, you then need the -f option with make to specify the name of the makefile. Using the default name of makefile just makes life easier.

You're probably trying to run Python 3 file with Python 2 interpreter. Currently (as of 2019), python command defaults to Python 2 when both versions are installed, on Windows and most Linux distributions.

But in case you're indeed working on a Python 2 script, a not yet mentioned on this page solution is to resave the file in UTF-8+BOM encoding, that will add three special bytes to the start of the file, they will explicitly inform the Python interpreter (and your text editor) about the file encoding.

If you're using bash....

#!/bin/bash

pushd $(dirname "${0}") > /dev/null
basedir=$(pwd -L)
# Use "pwd -P" for the path without links. man bash for more info.
popd > /dev/null

echo "${basedir}"

Swift 3:

self.btn.sendActions(for: .touchUpInside)

print_r($this->session->userdata); 

or

print_r($this->session->all_userdata());

Use like below code.

if(number >=0 ) {
            System.out.println("Number is natural and positive.");
}

Junit Rules work on the principle of AOP (aspect oriented programming). It intercepts the test method thus providing an opportunity to do some stuff before or after the execution of a particular test method.

Take the example of the below code:

public class JunitRuleTest {

  @Rule
  public TemporaryFolder tempFolder = new TemporaryFolder();

  @Test
  public void testRule() throws IOException {
    File newFolder = tempFolder.newFolder("Temp Folder");
    assertTrue(newFolder.exists());
  }
} 

Every time the above test method is executed, a temporary folder is created and it gets deleted after the execution of the method. This is an example of an out-of-box rule provided by Junit.

Similar behaviour can also be achieved by creating our own rules. Junit provides the TestRule interface, which can be implemented to create our own Junit Rule.

Here is a useful link for reference:

• http://www.codeaffine.com/2012/09/24/junit-rules/

textarea {
width: 700px;  
height: 100px;
resize: none; }

assign your required width and height for the textarea and then use. resize: none ; css property which will disable the textarea's stretchable property.

One other solution can be:

public int longToInt(Long longVariable)
{
    try { 
            return Integer.valueOf(longVariable.toString()); 
        } catch(IllegalArgumentException e) { 
               Log.e(e.printstackstrace()); 
        }
}

I have tried this for cases where the client is doing a POST and the server DB understands only Integers while the client has a Long.

A php file is run whenever you access it via an HTTP request be it GET,POST, PUT.

You can use JQuery/Ajax to send a request on a button click, or even just change the URL of the browser to navigate to the php address.

Depending on the data sent in the POST/GET you can have a switch statement running a different function.

Specifying Function via GET

You can utilize the code here: How to call PHP function from string stored in a Variable along with a switch statement to automatically call the appropriate function depending on data sent.

So on PHP side you can have something like this:

<?php

//see http://php.net/manual/en/function.call-user-func-array.php how to use extensively
if(isset($_GET['runFunction']) && function_exists($_GET['runFunction']))
call_user_func($_GET['runFunction']);
else
echo "Function not found or wrong input";

function test()
{
echo("test");
}

function hello()
{
echo("hello");
}

?>

and you can make the simplest get request using the address bar as testing:

http://127.0.0.1/test.php?runFunction=hellodddddd

results in:

Function not found or wrong input

http://127.0.0.1/test.php?runFunction=hello

results in:

hello

Since you have not defined what an empty file is. Some might consider a file with just blank lines also an empty file. So if you want to check if your file contains only blank lines (any whitespace character, '\r', '\n', '\t'), you can follow the example below:

Python3

import re

def whitespace_only(file):
    content = open(file, 'r').read()
    if re.search(r'^\s*$', content):
        return True

Explain: the example above uses regular expression (regex) to match the content (content) of the file.
Specifically: for regex of: ^\s*$ as a whole means if the file contains only blank lines and/or blank spaces.
- ^ asserts position at start of a line
- \s matches any whitespace character (equal to [\r\n\t\f\v ])
- * Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)
- $ asserts position at the end of a line

for nested arrays you can use:

$data = [
  'name[0]' = 'value 1',
  'name[1]' = 'value 2',
  'name[2]' = 'value 3',
  'id' = 'value 4',
  ....
];

With pandas version 0.16.1 and up, there is now a DataFrame.sample method built-in:

import pandas

df = pandas.DataFrame(pandas.np.random.random(100))

# Randomly sample 70% of your dataframe
df_percent = df.sample(frac=0.7)

# Randomly sample 7 elements from your dataframe
df_elements = df.sample(n=7)

For either approach above, you can get the rest of the rows by doing:

df_rest = df.loc[~df.index.isin(df_percent.index)]

There does not seem to be any standard immutable interface for dictionaries, so creating a wrapper seems like the only reasonable option, unfortunately.

Edit: Marc Gravell found the ILookup that I missed - that will allow you to at least avoid creating a new wrapper, although you still need to transform the Dictionary with .ToLookup().

If this is a need constrained to a specific scenario, you might be better off with a more business-logic-oriented interface:

interface IActiveUserCountProvider
{
    int GetMaxForServer(string serverName);
}

Put whatever you want to send to PHP in the value attribute.

  <select id="cmbMake" name="Make" >
     <option value="">Select Manufacturer</option>
     <option value="--Any--">--Any--</option>
     <option value="Toyota">Toyota</option>
     <option value="Nissan">Nissan</option>
  </select>

You can also omit the value attribute. It defaults to using the text.

If you don't want to change the HTML, you can put an array in your PHP to translate the values:

$makes = array(2 => 'Toyota',
               3 => 'Nissan');

$maker = $makes[$_POST['Make']];

https://github.com/kubernetes/helm/blob/master/docs/charts_tips_and_tricks.md#user-content-automatically-roll-deployments-when-configmaps-or-secrets-change

Often times configmaps or secrets are injected as configuration files in containers. Depending on the application a restart may be required should those be updated with a subsequent helm upgrade, but if the deployment spec itself didn't change the application keeps running with the old configuration resulting in an inconsistent deployment.

The sha256sum function can be used together with the include function to ensure a deployments template section is updated if another spec changes:

kind: Deployment
spec:
  template:
    metadata:
      annotations:
        checksum/config: {{ include (print $.Template.BasePath "/secret.yaml") . | sha256sum }}
[...]

In my case, for some reasons, $.Template.BasePath didn't work but $.Chart.Name does:

spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: admin-app
      annotations:
        checksum/config: {{ include (print $.Chart.Name "/templates/" $.Chart.Name "-configmap.yaml") . | sha256sum }}

Here is how to bulk-create entities from column-separated file, leaving aside all unquoting and un-escaping routines:

SomeModel(Model):
    @classmethod
    def from_file(model, file_obj, headers, delimiter):
        model.objects.bulk_create([

@owlstead, regarding your request for "a cryptographically secure variant of one of the given answers," please see RNCryptor. It was designed to do exactly what you're requesting (and was built in response to the problems with the code listed here).

RNCryptor uses PBKDF2 with salt, provides a random IV, and attaches HMAC (also generated from PBKDF2 with its own salt. It support synchronous and asynchronous operation.

1. Switch to Branch2

   git checkout Branch2
   

2. Apply the current (Branch2) changes on top of the Branch1 changes, staying in Branch2:

   git rebase Branch1
   

Which would leave you with the desired result in Branch2:

a -- b -- c                      <-- Master
           \
            d -- e               <-- Branch1
           \
            d -- e -- f' -- g'   <-- Branch2

You can delete Branch1.

You can test the rowcount

    $sqlStatement->execute( ...);
    if ($sqlStatement->rowCount() > 0)
    {
        return true;
    }

Note, while the modern form of updating submodule commits would be:

git submodule update --recursive --remote --merge --force

The older form was:

git submodule foreach --quiet git pull --quiet origin

Except... this second form is not really "quiet".

See commit a282f5a (12 Apr 2019) by Nguy?n Thái Ng?c Duy (pclouds).

submodule foreach: fix "<command> --quiet" not being respected

Robin reported that

git submodule foreach --quiet git pull --quiet origin

is not really quiet anymore.
It should be quiet before fc1b924 (submodule: port submodule subcommand 'foreach' from shell to C, 2018-05-10, Git v2.19.0-rc0) because parseopt can't accidentally eat options then.

"git pull" behaves as if --quiet is not given.

This happens because parseopt in submodule--helper will try to parse both --quiet options as if they are foreach's options, not git-pull's.
The parsed options are removed from the command line. So when we do pull later, we execute just this

git pull origin

When calling submodule helper, adding "--" in front of "git pull" will stop parseopt for parsing options that do not really belong to submodule--helper foreach.

PARSE_OPT_KEEP_UNKNOWN is removed as a safety measure. parseopt should never see unknown options or something has gone wrong. There are also a couple usage string update while I'm looking at them.

While at it, I also add "--" to other subcommands that pass "$@" to submodule--helper. "$@" in these cases are paths and less likely to be --something-like-this.
But the point still stands, git-submodule has parsed and classified what are options, what are paths.
submodule--helper should never consider paths passed by git-submodule to be options even if they look like one.

And Git 2.23 (Q3 2019) fixes another issue: "git submodule foreach" did not protect command line options passed to the command to be run in each submodule correctly, when the "--recursive" option was in use.

See commit 30db18b (24 Jun 2019) by Morian Sonnet (momoson).
^{(Merged by Junio C Hamano -- gitster -- in commit 968eecb, 09 Jul 2019)}

submodule foreach: fix recursion of options

Calling:

git submodule foreach --recursive <subcommand> --<option>

leads to an error stating that the option --<option> is unknown to submodule--helper.
That is of course only, when <option> is not a valid option for git submodule foreach.

The reason for this is, that above call is internally translated into a call to submodule--helper:

git submodule--helper foreach --recursive \
   -- <subcommand> --<option>

This call starts by executing the subcommand with its option inside the first level submodule and continues by calling the next iteration of the submodule foreach call

git --super-prefix <submodulepath> submodule--helper \
  foreach --recursive <subcommand> --<option>

inside the first level submodule. Note that the double dash in front of the subcommand is missing.

This problem starts to arise only recently, as the PARSE_OPT_KEEP_UNKNOWN flag for the argument parsing of git submodule foreach was removed in commit a282f5a.
Hence, the unknown option is complained about now, as the argument parsing is not properly ended by the double dash.

This commit fixes the problem by adding the double dash in front of the subcommand during the recursion.

Note that, before Git 2.29 (Q4 2020), "git submodule update --quiet"^(man) did not squelch underlying "rebase" and "pull" commands.

See commit 3ad0401 (30 Sep 2020) by Theodore Dubois (tbodt).
^{(Merged by Junio C Hamano -- gitster -- in commit 300cd14, 05 Oct 2020)}

submodule update: silence underlying merge/rebase with "--quiet"

^{Signed-off-by: Theodore Dubois}

Commands such as

$ git pull --rebase --recurse-submodules --quiet  

produce non-quiet output from the merge or rebase.
Pass the --quiet option down when invoking "rebase" and "merge".

Also fix the parsing of git submodule update^(man) -v.

When e84c3cf3 ("git-submodule.sh: accept verbose flag in cmd_update to be non-quiet", 2018-08-14, Git v2.19.0-rc0 -- merge) taught "git submodule update"^(man) to take "--quiet", it apparently did not know how ${GIT_QUIET:+--quiet} works, and reviewers seem to have missed that setting the variable to "0", rather than unsetting it, still results in "--quiet" being passed to underlying commands.

1. Declare the variable
2. Set it by your command and add dynamic parts like use parameter values of sp(here @IsMonday and @IsTuesday are sp params)

3. execute the command

   declare  @sql varchar (100)
   set @sql ='select * from #td1'
   
   if (@IsMonday+@IsTuesday !='')
   begin
   set @sql= @sql+' where PickupDay in ('''+@IsMonday+''','''+@IsTuesday+''' )'
   end
   exec( @sql)
   

For Swift 4.+

extension UIView {
     public func removeAllSubViews() {
          self.subviews.forEach({ $0.removeFromSuperview() })

}

i hope this is use full for you.

You don't need the directory on your path. You could put it on your path, but you don't NEED to do that.
If you are calling regasm rarely, or calling it from a batch file, you may find it is simpler to just invoke regasm via the fully-qualified pathname on the exe, eg:

c:\Windows\Microsoft.NET\Framework\v2.0.50727\regasm.exe   MyAssembly.dll

On an unrelated task, I recently brought up our MySQL database in MySQL Workbench, and when viewing the table relations for the above tables, I noticed 'duplicate' and/or spurious relations that I had somehow missed before (they weren't showing up in PHPMyAdmin FWIW). Removing these extra relations cleared up the issue immediately.

As @fijaaron says,

1. GRANT ALL does not imply GRANT FILE
2. GRANT FILE only works with *.*

So do

GRANT FILE ON *.* TO user;

https://github.com/requery/sqlite-android allows you to query JSON fields (and arrays in them, I've tried it and am using it). Before that I was just storing JSON strings into a TEXT column. It supports FTS3, FTS4, & JSON1

As of July 2019, it still gets version bumps every now and then, so it isn't a dead project.

• https://www.sqlite.org/json1.html (store and query JSON documents)
• https://www.sqlite.org/fts3.html (perform full-text searches)

Uri.EscapeDataString or HttpUtility.UrlEncode is the correct way to escape a string meant to be part of a URL.

Take for example the string "Stack Overflow":

• HttpUtility.UrlEncode("Stack Overflow") --> "Stack+Overflow"

• Uri.EscapeUriString("Stack Overflow") --> "Stack%20Overflow"

• Uri.EscapeDataString("Stack + Overflow") --> Also encodes "+" to "%2b" ---->Stack%20%2B%20%20Overflow

Only the last is correct when used as an actual part of the URL (as opposed to the value of one of the query string parameters)

We can easily place the background image in PercentFrameLayout using the ImageView. We have to set the scaleType attribute value="fitXY" and in the foreground we can also display other view's like textview or button.

 <android.support.percent.PercentFrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        >
        <ImageView
            android:src="@drawable/logo"
            android:id="@+id/im1"
            android:scaleType="fitXY"
            android:layout_height="match_parent"
            android:layout_width="match_parent"/>
<EditText android:layout_gravity="center_horizontal"
        android:hint="Enter Username"
        android:id="@+id/et1"
        android:layout_height="wrap_content"
        app:layout_widthPercent="50%"
        app:layout_marginTopPercent="30%"
        />
<Button
    android:layout_gravity="center_horizontal"
    android:text="Login"
    android:id="@+id/b1"
    android:layout_height="wrap_content"
    app:layout_widthPercent="50%"
    app:layout_marginTopPercent="40%"/>
</android.support.percent.PercentFrameLayout>

There are couple of way which can be used.

const stations = [
  {call:'station one',frequency:'000'},
  {call:'station two',frequency:'001'}
];
const callList = stations.map(({call}) => call)

Solution 1

<p>{callList.join(', ')}</p>

Solution 2

<ol>    
  { callList && callList.map(item => <li>{item}</li>) }
</ol>

Of course there are other ways also available.

I got this issue because of a rather silly mistake. I had forgotten to hook my service configuration procedure to discover controllers automatically in the ASP.NET Core application.

Adding this method solved it:

// Add framework services.
            services.AddMvc()
                    .AddControllersAsServices();      // <---- Super important

Are you looking for the max date for each model?

SELECT model, max(date) FROM doc
GROUP BY model

If you're looking for all models matching the max date of the entire table...

SELECT model, date FROM doc
WHERE date IN (SELECT max(date) FROM doc)

[--- Added ---]

For those who want to display details from every record matching the latest date within each model group (not summary data, as asked for in the OP):

SELECT d.model, d.date, d.color, d.etc FROM doc d
WHERE d.date IN (SELECT max(d2.date) FROM doc d2 WHERE d2.model=d.model)

MySQL 8.0 and newer supports the OVER clause, producing the same results a bit faster for larger data sets.

SELECT model, date, color, etc FROM (SELECT model, date, color, etc, 
  max(date) OVER (PARTITION BY model) max_date FROM doc) predoc 
WHERE date=max_date;

There are errors in your functions, but the first thing you should do, is to set the body tag correctly:

<body>
<p><span id="go" class="georgia">go</span> Italian</p>
<p>
    <button id="on" type="button" value="turn on">turn on</button>
    <button id="off" type="button" value="turn off">turn off</button>
</p>
</body>

<script>....</script>

The problem sometimes may be, that you call 'var text' and the other vars only once, when the script starts. If you make changements to the DOM, this static solution may be harmful.

So you could try this (this is more flexible approach and using function parameters, so you can call the functions on any element):

<body>
<p><span id="go" class="georgia">go</span> Italian</p>
<p>
    <button type="button" value="turn on"
         onclick=turnOn("go")>turn on</button>
    <button type="button" value="turn off"
         onclick=turnOff()>turn off</button>
</p>
</body>

<script type="text/JavaScript">
var interval;

var turnOn = function(elementId){
    interval = setInterval(function(){fontChange(elementId);}, 500);
};

var turnOff = function(){
    clearInterval(interval);
};

var fontChange = function(elementId) {
    var text = document.getElementById(elementId);
    switch(text.className) {
        case "georgia":
            text.className = "arial";
            break;
        case "arial":
            text.className = "courierNew";
            break;
        case "courierNew":
            text.className = "georgia";
            break;      
    }
};
</script>

You don't need this anymore, so delete it:

var text = document.getElementById("go");
var on = document.getElementById("on");
var off = document.getElementById("off");

This is dynamic code, meaning JS code which runs generic and doesn't adress elements directly. I like this approach more than defining an own function for every div element. ;)

Arrays.asList(array);    

Example:

 List<String> stooges = Arrays.asList("Larry", "Moe", "Curly");

See Arrays.asList class documentation.

def get_code(str)
  str.sub(/^(Z_.*): .*/, '\1')
end
get_code('Z_foo: bar!') # => "Z_foo"

You can use JSON.stringify(object) with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array)), which is the following code (more detail can be found on this answer):

// Convert array to object
var convArrToObj = function(array){
    var thisEleObj = new Object();
    if(typeof array == "object"){
        for(var i in array){
            var thisEle = convArrToObj(array[i]);
            thisEleObj[i] = thisEle;
        }
    }else {
        thisEleObj = array;
    }
    return thisEleObj;
}

To make it more generic, you can override the JSON.stringify function and you won't have to worry about it again, to do this, just paste this at the top of your page:

// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        return oldJSONStringify(convArrToObj(input));
    };
})();

And now JSON.stringify will accept arrays or objects! (link to jsFiddle with example)

Edit:

Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array) always returns [], which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify with an object):

(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

You could also use vbCrLf which corresponds to Chr(13) & Chr(10).

Complementing the response of @Adrià Cidre you can do:

status=$(ssh -o BatchMode=yes -o ConnectTimeout=5 user@host echo ok 2>&1)

if [[ $status == ok ]] ; then
  echo auth ok, do something
elif [[ $status == "Permission denied"* ]] ; then
  echo no_auth
else
  echo other_error

1. __str__ must return string object whereas __repr__ can return any python expression.
2. If __str__ implementation is missing then __repr__ function is used as fallback. There is no fallback if __repr__ function implementation is missing.
3. If __repr__ function is returning String representation of the object, we can skip implementation of __str__ function.

I tried this in one of the codeacademy exercises (reversing chars in a string without using reversed nor :: -1)

def reverse(text):
    chars= []
    l = len(text)
    last = l-1
    for i in range (l):
        chars.append(text[last])
        last-=1

    result= ""   
    for c in chars:
        result += c
    return result
print reverse('hola')

To complement the Perl one-liner, here's its awk equivalent:

awk 'NR==FNR{arr[$0];next} $0 in arr' file1 file2

This will read all lines from file1 into the array arr[], and then check for each line in file2 if it already exists within the array (i.e. file1). The lines that are found will be printed in the order in which they appear in file2. Note that the comparison in arr uses the entire line from file2 as index to the array, so it will only report exact matches on entire lines.

This is actually a multi-step process. First you'll need to add all your files to the current stage:

git add .

You can verify that your files will be added when you commit by checking the status of the current stage:

git status

The console should display a message that lists all of the files that are currently staged, like this:

# On branch master
#
# Initial commit
#
# Changes to be committed:
#   (use "git rm --cached <file>..." to unstage)
#
#   new file:   README
#   new file:   src/somefile.js
#

If it all looks good then you're ready to commit. Note that the commit action only commits to your local repository.

git commit -m "some message goes here"

If you haven't connected your local repository to a remote one yet, you'll have to do that now. Assuming your remote repository is hosted on GitHub and named "Some-Awesome-Project", your command is going to look something like this:

git remote add origin [email protected]:username/Some-Awesome-Project

It's a bit confusing, but by convention we refer to the remote repository as 'origin' and the initial local repository as 'master'. When you're ready to push your commits to the remote repository (origin), you'll need to use the 'push' command:

git push origin master

Simple but dirty way

// Swift 1.2
if let intValue = "42".toInt() {
    let number1 = NSNumber(integer:intValue)
}
// Swift 2.0
let number2 = Int(stringNumber)

// Using NSNumber
let number3 = NSNumber(float:("42.42" as NSString).floatValue)

The extension-way

This is better, really, because it'll play nicely with locales and decimals.

extension String {

    var numberValue:NSNumber? {
        let formatter = NSNumberFormatter()
        formatter.numberStyle = .DecimalStyle
        return formatter.numberFromString(self)
    }
}

Now you can simply do:

let someFloat = "42.42".numberValue
let someInt = "42".numberValue

Its late, yet it's worth your time nothing that, there are some differences in browser level implementation of focusin and focusout events and react synthetic onFocus and onBlur. focusin and focusout actually bubble, while onFocus and onBlur dont. So there is no exact same implementation for focusin and focusout as of now for react. Anyway most cases will be covered in onFocus and onBlur.

Building on dtheodor's answer you could use something similar to the below to ensure that you don't forget to unregister the callback... Some may object to passing the $scope to a service though.

factory('aService', function() {
  var observerCallbacks = [];

  /**
   * Registers a function that will be called when
   * any modifications are made.
   *
   * For convenience the callback is called immediately after registering
   * which can be prevented with `preventImmediate` param.
   *
   * Will also automatically unregister the callback upon scope destory.
   */
  this.registerObserver = function($scope, cb, preventImmediate){
    observerCallbacks.push(cb);

    if (preventImmediate !== true) {
      cb();
    }

    $scope.$on('$destroy', function () {
      observerCallbacks.remove(cb);
    });
  };

  function notifyObservers() {
    observerCallbacks.forEach(function (cb) {
      cb();
    });
  };

  this.foo = someNgResource.query().$then(function(){
    notifyObservers();
  });
});

Array.remove is an extension method which looks like this:

/**
 * Removes the given item the current array.
 *
 * @param  {Object}  item   The item to remove.
 * @return {Boolean}        True if the item is removed.
 */
Array.prototype.remove = function (item /*, thisp */) {
    var idx = this.indexOf(item);

    if (idx > -1) {
        this.splice(idx, 1);

        return true;
    }
    return false;
};

probably you are not giving the same name as you mentioned in the upload.single('file') .

Could it be a problem with past preview versions of Android Studio ? nowadays "beta" has replaced the "preview". I try it out step by step debugging while using Memory Monitor at same time by Android Studio (Beta) 0.8.11 on OSX 10.9.5 without any problems.

The tutorial Debugging with Android Studio also helps, specially this paragraph :

To track memory allocation of objects:

1. Start your app as described in Run Your App in Debug Mode.
2. Click Android to open the Android DDMS tool window.
3. On the Android DDMS tool window, select the Devices | logcat tab.
4. Select your device from the dropdown list.
5. Select your app by its package name from the list of running apps.
6. Click Start Allocation Tracking Interact with your app on the device. Click Stop Allocation Tracking

Here a couple of screenshot while debugging step by step on a breakpoint a monitoring the memory on the emulator:

import os
print os.getcwd()  # Prints the current working directory

To set the working directory:

os.chdir('c:\\Users\\uname\\desktop\\python')  # Provide the new path here

You can run the following query to check for the existance of the user table.

SELECT * FROM information_schema.TABLES
WHERE TABLE_NAME LIKE '%user%'

See if you can find a row with the following values in

mysql   user    BASE TABLE  MyISAM  

If you cant find this table look at the following link to rebuild the database How to recover/recreate mysql's default 'mysql' database

$output = curl_exec($ch);
$result = iconv("Windows-1251", "UTF-8", $output);

As per the MDN Specifications, X-Frame-Options: ALLOW-FROM is not supported in Chrome and support is unknown in Edge and Opera.

Content-Security-Policy: frame-ancestors overrides X-Frame-Options (as per this W3 spec), but frame-ancestors has limited compatibility. As per these MDN Specs, it's not supported in IE or Edge.

You may hit this problem while using Knockout JS. If you try setting class attribute like the example below it will fail:

<span data-bind="attr: { class: something() }"></span>

Escape the class string like this:

<span data-bind="attr: { 'class': something() }"></span>

My 2 cents.

The best way is by switch-ing between v.getId(). Having separate anonymous OnClickListener for each Button is taking up more memory. Casting View to Button is unnecessary. Using if-else when switch is possible is slower and harder to read. In Android's source you can often notice comparing the references by if-else:

if (b1 == v) {
 // ...
} else if (b2 == v) {

I don't know exactly why they chose this way, but it works too.

That's actually pretty easy, here's a possible approach:

<table>
    <tr>
        <th>
            <a href="?orderBy=type">Type:</a>
        </th>
        <th>
            <a href="?orderBy=description">Description:</a>
        </th>
        <th>
            <a href="?orderBy=recorded_date">Recorded Date:</a>
        </th>
        <th>
            <a href="?orderBy=added_date">Added Date:</a>
        </th>
    </tr>
</table>
<?php
$orderBy = array('type', 'description', 'recorded_date', 'added_date');

$order = 'type';
if (isset($_GET['orderBy']) && in_array($_GET['orderBy'], $orderBy)) {
    $order = $_GET['orderBy'];
}

$query = 'SELECT * FROM aTable ORDER BY '.$order;

// retrieve and show the data :)
?>

That'll do the trick! :)

EXEC sp_MSforeachtable 'if PARSENAME("?",1) like ''%CertainString%'' DROP TABLE ?'

sp_MSforeachtable is undocumented hence not suitable for production because it's behavior may vary depending on MS_SQL version.

Some short codes:-

1. checkout (co)
2. commit (ci)
3. copy (cp)
4. delete (del, remove,rm)
5. diff (di)

You can convert any thing to anything using this function:

template<class T = std::string, class U>
T to(U a) {
    std::stringstream ss;
    T ret;
    ss << a;
    ss >> ret;
    return ret;
};

usage :

std::string str = to(2.5);
double d = to<double>("2.5");

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

I don't think you can. Your best option might be to encapsulate the thing you want to pass "by ref" onto another class instance, and pass the (outer) class's reference (by value). If you see what I mean...

i.e. your method changes the internal state of the object it is passed, which is then visible to the caller.

I tried all of the above solutions numerous times but none worked for me. I was using Visual Studio 2015 with ReSharper 9.0.

I was able to resolve this by upgrading to ReSharper 9.2. If you already have the latest update for your major version, maybe reinstalling ReSharper might fix this for you. I would suggest clearing you ReShaper cache first, just in case.

Here's the link to the archive versions of ReSharper: https://resharper-support.jetbrains.com/hc/en-us/articles/207242355-Where-can-I-download-an-old-previous-ReSharper-version-

You can get this error if you use wrong mode when opening the file. For example:

    with open(output, 'wb') as output_file:
        print output_file.read()

In that code, I want to read the file, but I use mode wb instead of r or r+

In PostMan we have ->Pre-request Script. Paste the Below snippet.

const dateNow = new Date();
postman.setGlobalVariable("todayDate", dateNow.toLocaleDateString());

And now we are ready to use.

{
"firstName": "SANKAR",
"lastName": "B",
"email": "[email protected]",
"creationDate": "{{todayDate}}"
}

If you are using JPA Entity classes then use the below snippet

    @JsonFormat(pattern="MM/dd/yyyy")
    @Column(name = "creation_date")
    private Date creationDate;

enter image description here enter image description here

Solution:

@Entity
@Table(name = "USER")
@Access(AccessType.FIELD)
public class User implements UserDetails, Serializable {

    private static final long serialVersionUID = 2L;

    @Id
    @Column(name = "USER_ID", updatable=false, nullable=false)
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @Column(name = "USERNAME")
    private String username;

    @Column(name = "PASSWORD")
    private String password;

    @Column(name = "NAME")
    private String name;

    @Column(name = "EMAIL")
    private String email;

    @Column(name = "LOCKED")
    private boolean locked;

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, targetEntity = Role.class)
    @JoinTable(name = "USER_ROLE", joinColumns = { @JoinColumn(name = "USER_ID") }, inverseJoinColumns = { @JoinColumn(name = "ROLE_ID") })
    private Set<Role> roles;

    @Override
    public GrantedAuthority[] getAuthorities() {
        List<GrantedAuthorityImpl> list = new ArrayList<GrantedAuthorityImpl>(0);
        for (Role role : roles) {
            list.add(new GrantedAuthorityImpl(role.getRole()));
        }
        return (GrantedAuthority[]) list.toArray(new GrantedAuthority[list.size()]);
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return !isLocked();
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    @Override
    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    @Override
    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getName() {
        return name;
    }

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

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public boolean isLocked() {
        return locked;
    }

    public void setLocked(boolean locked) {
        this.locked = locked;
    }

    public Set<Role> getRoles() {
        return roles;
    }

    public void setRoles(Set<Role> roles) {
        this.roles = roles;
    }
}

Role.java same as above.

try this:

"String goes here".PadLeft(20,' ');
"String goes here".PadRight(20,' ');

for the center get the length of the string and do padleft and padright with the necessary characters

int len = "String goes here".Length;
int whites = len /2;
"String goes here".PadRight(len + whites,' ').PadLeft(len + whites,' ');

How about using a drop-in solution like ShareThis or AddThis? They have similar functionality, so it's quite possible they already solved the problem.

AddThis's code has a huge if/else browser version fork for saving favorites, though, with most branches ending in prompting the user to manually add the favorite themselves, so I am thinking that no such pure JavaScript implementation exists.

Otherwise, if you only need to support IE and Firefox, you have IE's window.externalAddFavorite( ) and Mozilla's window.sidebar.addPanel( ).

function changeImage(a) so there is no such thing as a.src => just use a.

You can also create shapes directly inside the item tag, in case you want to add some more details to your view, like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape>
            <solid android:color="#81ba73" />
            <corners android:radius="6dp" />
        </shape>
        <ripple android:color="#c62828"/>
    </item>
    <item android:state_enabled="false">
        <shape>
            <solid android:color="#788e73" />
            <corners android:radius="6dp" />
        </shape>
    </item>
    <item>
        <shape>
            <solid android:color="#add8a3" />
            <corners android:radius="6dp" />
        </shape>
    </item>
</selector>

Beware that Android will cycle through the items from top to bottom, therefore, you must place the item without condition on the bottom of the list (so it acts like a default/fallback).

I had this need once and created a small library for, which maintains the CSS documents

https://github.com/terotests/css

With that you can state

css().bind("TD:hover", {
        "background" : "00ff00"
    });

It uses the techniques mentioned above and also tries to take care of the cross-browser issues. If there for some reason exists an old browser like IE9 it will limit the number of STYLE tags, because the older IE browser had this strange limit for number of STYLE tags available on the page.

Also, it limits the traffic to the tags by updating tags only periodically. There is also a limited support for creating animation classes.

Try this:

tar -czf my.tar.gz dir/

But are you sure you are not compressing some .exe file or something? Maybe the problem is not with te compression, but with the files you are compressing?

You can also use Object Oriented Programming (OOP) instead of procedural programming:

$fiveDays = new DateInterval('P5D');
$today = new DateTime();
$fiveDaysAgo = $today->sub(fiveDays); // or ->add(fiveDays); to add 5 days

Or with just one line of code:

$fiveDaysAgo = (new DateTime())->sub(new DateInterval('P5D'));

Try this another way:

var qry = Employees
          .OrderByDescending (s => s.EmpFName)
          .ThenBy (s => s.Address)
          .Select (s => s.EmpCode);

Queryable.ThenBy

I assume your column type is STRING (CHAR, VARCHAR, etc) and sorting procedure is sorting it as a string. What you need to do is to convert value into numeric value. How to do it will depend on SQL system you use.

Yet another option would be:

SELECT * FROM mytable
 WHERE TRUNC(mydate, 'YEAR') = TRUNC(SYSDATE, 'YEAR');

Simply Use

 FragmentManager fm = getActivity().getSupportFragmentManager();

Remember always when accessing fragment inflating in MainLayout use Casting or getActivity().

To select by class, you can do this:

$("input.className:checkbox:not(:checked)")

Use this PRINT BIG function to output everything:

IF OBJECT_ID('tempdb..#printBig') IS NOT NULL
  DROP PROCEDURE #printBig

GO

CREATE PROCEDURE #printBig (
   @text NVARCHAR(MAX)
 )
AS

--DECLARE @text NVARCHAR(MAX) = 'YourTextHere'
DECLARE @lineSep NVARCHAR(2) = CHAR(13) + CHAR(10)  -- Windows \r\n

DECLARE @off INT = 1
DECLARE @maxLen INT = 4000
DECLARE @len INT

WHILE @off < LEN(@text)
BEGIN

  SELECT @len =
    CASE
      WHEN LEN(@text) - @off - 1 <= @maxLen THEN LEN(@text)
      ELSE @maxLen
             - CHARINDEX(REVERSE(@lineSep),  REVERSE(SUBSTRING(@text, @off, @maxLen)))
             - LEN(@lineSep)
             + 1
    END
  PRINT SUBSTRING(@text, @off, @len)
  --PRINT '@off=' + CAST(@off AS VARCHAR) + ' @len=' + CAST(@len AS VARCHAR)
  SET @off += @len + LEN(@lineSep)

END

Actually, I think that the answer given in the question you mentioned is just wrong (UPDATE - 20101106: someone fixed it, this answer refers to the version preceding the edit) and this explains, at least partially, why you run into troubles.

It generates two jar files in logmanager/target: logmanager-0.1.0.jar, and logmanager-0.1.0-jar-with-dependencies.jar.

The first one is the JAR of the logmanager module generated during the package phase by jar:jar (because the module has a packaging of type jar). The second one is the assembly generated by assembly:assembly and should contain the classes from the current module and its dependencies (if you used the descriptor jar-with-dependencies).

I get an error when I double-click on the first jar:

Could not find the main class: com.gorkwobble.logmanager.LogManager. Program will exit.

If you applied the suggested configuration of the link posted as reference, you configured the jar plugin to produce an executable artifact, something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.gorkwobble.logmanager.LogManager</mainClass>
        </manifest>
      </archive>
    </configuration>
  </plugin>

So logmanager-0.1.0.jar is indeed executable but 1. this is not what you want (because it doesn't have all dependencies) and 2. it doesn't contain com.gorkwobble.logmanager.LogManager (this is what the error is saying, check the content of the jar).

A slightly different error when I double-click the jar-with-dependencies.jar:

Failed to load Main-Class manifest attribute from: C:\EclipseProjects\logmanager\target\logmanager-0.1.0-jar-with-dependencies.jar

Again, if you configured the assembly plugin as suggested, you have something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
    </configuration>
  </plugin>

With this setup, logmanager-0.1.0-jar-with-dependencies.jar contains the classes from the current module and its dependencies but, according to the error, its META-INF/MANIFEST.MF doesn't contain a Main-Class entry (its likely not the same MANIFEST.MF as in logmanager-0.1.0.jar). The jar is actually not executable, which again is not what you want.

So, my suggestion would be to remove the configuration element from the maven-jar-plugin and to configure the maven-assembly-plugin like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.2</version>
    <!-- nothing here -->
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-4</version>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
          <mainClass>org.sample.App</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

Of course, replace org.sample.App with the class you want to have executed. Little bonus, I've bound assembly:single to the package phase so you don't have to run assembly:assembly anymore. Just run mvn install and the assembly will be produced during the standard build.

So, please update your pom.xml with the configuration given above and run mvn clean install. Then, cd into the target directory and try again:

java -jar logmanager-0.1.0-jar-with-dependencies.jar

If you get an error, please update your question with it and post the content of the META-INF/MANIFEST.MF file and the relevant part of your pom.xml (the plugins configuration parts). Also please post the result of:

java -cp logmanager-0.1.0-jar-with-dependencies.jar com.gorkwobble.logmanager.LogManager

to demonstrate it's working fine on the command line (regardless of what eclipse is saying).

EDIT: For Java 6, you need to configure the maven-compiler-plugin. Add this to your pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>

There are only two options:

• Find out by reading all rows (and then you might as well store them)

• run a specialized SELECT COUNT(*) query beforehand.

Going twice through the DataReader loop is really expensive, you would have to re-execute the query.

And (thanks to Pete OHanlon) the second option is only concurrency-safe when you use a transaction with a Snapshot isolation level.

Since you want to end up storing all rows in memory anyway the only sensible option is to read all rows in a flexible storage (List<> or DataTable) and then copy the data to any format you want. The in-memory operation will always be much more efficient.

Finds an IP address of this computer in a network which is a default gateway (for example excludes all virtual networks, docker bridges) eg. internet gateway, wifi gateway, ethernet

ip route| grep $(ip route |grep default | awk '{ print $5 }') | grep -v "default" | awk '/scope/ { print $9 }'

Works on Linux.

Test:

Based on what I've read and my experience with Django so far, auto_now_add is buggy. I agree with jthanism --- override the normal save method it's clean and you know what's hapenning. Now, to make it dry, create an abstract model called TimeStamped:

from django.utils import timezone

class TimeStamped(models.Model):
    creation_date = models.DateTimeField(editable=False)
    last_modified = models.DateTimeField(editable=False)

    def save(self, *args, **kwargs):
        if not self.creation_date:
            self.creation_date = timezone.now()

        self.last_modified = timezone.now()
        return super(TimeStamped, self).save(*args, **kwargs)

    class Meta:
        abstract = True

And then, when you want a model that has this time-stampy behavior, just subclass:

MyNewTimeStampyModel(TimeStamped):
    field1 = ...

If you want the fields to show up in admin, then just remove the editable=False option

This is totally system dependent. You should experiment to find the optimum solution. Try starting with bs=8388608. (As Hitachi HDDs seems to have 8MB cache.)

I have found the SMB2 protocol introduced in Vista to lock the access databases. It can be disabled by the following regedit:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters] "Smb2"=dword:00000000

You can use Numeric#step.

0.step(30,5) do |num|
  puts "number is #{num}"
end
# >> number is 0
# >> number is 5
# >> number is 10
# >> number is 15
# >> number is 20
# >> number is 25
# >> number is 30

Simply, @Id: This annotation specifies the primary key of the entity. 

@GeneratedValue: This annotation is used to specify the primary key generation strategy to use. i.e Instructs database to generate a value for this field automatically. If the strategy is not specified by default AUTO will be used. 

GenerationType enum defines four strategies: 
1. Generation Type . TABLE, 
2. Generation Type. SEQUENCE,
3. Generation Type. IDENTITY   
4. Generation Type. AUTO

GenerationType.SEQUENCE

With this strategy, underlying persistence provider must use a database sequence to get the next unique primary key for the entities. 

GenerationType.TABLE

With this strategy, underlying persistence provider must use a database table to generate/keep the next unique primary key for the entities. 

GenerationType.IDENTITY
This GenerationType indicates that the persistence provider must assign primary keys for the entity using a database identity column. IDENTITY column is typically used in SQL Server. This special type column is populated internally by the table itself without using a separate sequence. If underlying database doesn't support IDENTITY column or some similar variant then the persistence provider can choose an alternative appropriate strategy. In this examples we are using H2 database which doesn't support IDENTITY column.

GenerationType.AUTO
This GenerationType indicates that the persistence provider should automatically pick an appropriate strategy for the particular database. This is the default GenerationType, i.e. if we just use @GeneratedValue annotation then this value of GenerationType will be used.

Oh, god! After spending several hours and downloading the Android sources, I have finally come to a solution.

If you look at the Activity class, you will see, that finish() method only sends back the result if there is a mParent property set to null. Otherwise the result is lost.

public void finish() {
    if (mParent == null) {
        int resultCode;
        Intent resultData;
        synchronized (this) {
            resultCode = mResultCode;
            resultData = mResultData;
        }
        if (Config.LOGV) Log.v(TAG, "Finishing self: token=" + mToken);
        try {
            if (ActivityManagerNative.getDefault()
                .finishActivity(mToken, resultCode, resultData)) {
                mFinished = true;
            }
        } catch (RemoteException e) {
            // Empty
        }
    } else {
        mParent.finishFromChild(this);
    }
}

So my solution is to set result to the parent activity if present, like that:

Intent data = new Intent();
 [...]
if (getParent() == null) {
    setResult(Activity.RESULT_OK, data);
} else {
    getParent().setResult(Activity.RESULT_OK, data);
}
finish();

I hope that will be helpful if someone looks for this problem workaround again.

One property of this approach that has not been pointed out so far is that because you create inner classes, the whole containing class is captured in its scope. This means that as long as your Set is alive, it will retain a pointer to the containing instance (this$0) and keep that from being garbage-collected, which could be an issue.

This, and the fact that a new class gets created in the first place even though a regular HashSet would work just fine (or even better), makes me not want to use this construct (even though I really long for the syntactic sugar).

Second question: The new HashSet must be the "this" used in the instance initializer ... can anyone shed light on the mechanism? I'd have naively expected "this" to refer to the object initializing "flavors".

This is just how inner classes work. They get their own this, but they also have pointers to the parent instance, so that you can call methods on the containing object as well. In case of a naming conflict, the inner class (in your case HashSet) takes precedence, but you can prefix "this" with a classname to get the outer method as well.

public class Test {

    public void add(Object o) {
    }

    public Set<String> makeSet() {
        return new HashSet<String>() {
            {
              add("hello"); // HashSet
              Test.this.add("hello"); // outer instance 
            }
        };
    }
}

To be clear on the anonymous subclass being created, you could define methods in there as well. For example override HashSet.add()

    public Set<String> makeSet() {
        return new HashSet<String>() {
            {
              add("hello"); // not HashSet anymore ...
            }

            @Override
            boolean add(String s){

            }

        };
    }

as in this post, using .is and the attribute selector [], you can easily add a function (or prototype):

function hasAttr($sel,attr) {
    return $sel.is('['+attr+']');
}

The AddRange method

aList.AddRange( anotherList );

For legend labels can use something like below. Legendlabels are the plot lines saved. modFreq are where the name of the actual labels corresponding to the plot lines. Then the third parameter is the location of the legend. Lastly, you can pass in any arguments as I've down here but mainly need the first three. Also, you are supposed to if you set the labels correctly in the plot command. To just call legend with the location parameter and it finds the labels in each of the lines. I have had better luck making my own legend as below. Seems to work in all cases where have never seemed to get the other way going properly. If you don't understand let me know:

legendLabels = []
for i in range(modSize):
    legendLabels.append(ax.plot(x,hstack((array([0]),actSum[j,semi,i,semi])), color=plotColor[i%8], dashes=dashes[i%4])[0]) #linestyle=dashs[i%4]       
legArgs = dict(title='AM Templates (Hz)',bbox_to_anchor=[.4,1.05],borderpad=0.1,labelspacing=0,handlelength=1.8,handletextpad=0.05,frameon=False,ncol=4, columnspacing=0.02) #ncol,numpoints,columnspacing,title,bbox_transform,prop
leg = ax.legend(tuple(legendLabels),tuple(modFreq),'upper center',**legArgs)
leg.get_title().set_fontsize(tick_size)

You can also use the leg to change fontsizes or nearly any parameter of the legend.

Global title as stated in the above comment can be done with adding text per the link provided: http://matplotlib.sourceforge.net/examples/pylab_examples/newscalarformatter_demo.html

f.text(0.5,0.975,'The new formatter, default settings',horizontalalignment='center',
       verticalalignment='top')

Command-line approach

mkdir android-sdk
cd android-sdk
wget https://dl.google.com/android/repository/sdk-tools-linux-*.zip
unzip sdk-tools-linux-*.zip
tools/bin/sdkmanager --update

When executing the above commands, make sure that you replace * with an appropriate version number which you could find in the download page.

Installing packages

You can also use the sdkmanager to list and to install any specific packages needed.

tools/bin/sdkmanager --list
tools/bin/sdkmanager "platform-tools" "platforms;android–27" "build-tools;27.0.3"

FYI

sdk-tools-linux-*.zip only includes the command-line tools. This extracts content to a single directory named tools, like:

+- android-sdk
    +- tools

To get the SDK packages we could run:

tools/bin/sdkmanager --update

The sdkmanager accepts the following flag:

--sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK 
                          containing this tool

But if we omit this flag, it assumes parent directory of tools directory as the sdk root, here in our case android-sdk directory.

If you check the android-sdk folder after running tools/bin/sdkmanager --update it will be like:

+- android-sdk
    +- tools
    +- emulator  
    +- platforms  
    +- platform-tool

If needed, also set ANDROID_HOME environment variable like:

export ANDROID_HOME=/path/to/android-sdk

use this filter:

(dns.flags.response == 0) and (ip.src == 159.25.78.7)

what this query does is it only gives dns queries originated from your ip

For those lost souls on google, using numpy.expand_dims then numpy.repeat will work, and will also work in higher dimensional cases (i.e. multiplying a shape (10, 12, 3) by a (10, 12)).

>>> import numpy
>>> a = numpy.array([[1,2,3],[4,5,6],[7,8,9]])
>>> b = numpy.array([0,1,2])
>>> b0 = numpy.expand_dims(b, axis = 0)
>>> b0 = numpy.repeat(b0, a.shape[0], axis = 0)
>>> b1 = numpy.expand_dims(b, axis = 1)
>>> b1 = numpy.repeat(b1, a.shape[1], axis = 1)
>>> a*b0
array([[ 0,  2,  6],
   [ 0,  5, 12],
   [ 0,  8, 18]])
>>> a*b1
array([[ 0,  0,  0],
   [ 4,  5,  6],
   [14, 16, 18]])

I think your only option here is a constant. With that said - don't use it - stick with nulls instead of bogus dates.

create table atable
(
  atableID int IDENTITY(1, 1) PRIMARY KEY CLUSTERED,
  Modified datetime DEFAULT '1/1/1753'
)

Share my stupid thought:

Maybe I can select distinct only on c1 but not on c2, so the syntax may be select ([distinct] col)+ where distinct is a qualifier for each column.

But after thought, I find that distinct on only one column is nonsense. Take the following relationship:

   | A | B
__________
  1| 1 | 2
  2| 1 | 1

If we select (distinct A), B, then what is the proper B for A = 1?

Thus, distinct is a qualifier for a statement.

Just add the display:block to the thead > tr and tbody. check the below example

Put in all your svg:

fill="var(--svgcolor)"

In Css:

:root {
  --svgcolor: tomato;
}

To use pseudo-classes:

span.github:hover {
  --svgcolor:aquamarine;
}

Explanation

root = html page.
--svgcolor = a variable.
span.github = selecting a span element with a class github, a svg icon inside and assigning pseudo-class hover.

For me it was due to insufficient disk space , and it was resolved after I freed up some disk space on my local drive.

This is normally the case then the ID is not a natural part of the entity, but a database artifact that needs be abstracted away.

It is a design decision - to only allow setting the ID during construction or through method invocation, so it is managed internally by the class.

You can write a setter yourself, assuming you have a backing field:

private int Id = 0;
public void SetId (int id)
{
  this.Id = id;
}

Or through a constructor:

private int Id = 0;
public Person (int id)
{
  this.Id = id;
}

You can try Thread.currentThread().isDaemon()

This is similar to Emilie's answer however since you asked specifically how to convert the NSRange to Range<String.Index> you would do something like this:

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {

     let start = advance(textField.text.startIndex, range.location) 
     let end = advance(start, range.length) 
     let swiftRange = Range<String.Index>(start: start, end: end) 
     ...

}

'pywin32' is its canonical name.

Year(Date)

Year(): Returns the year portion of the date argument.
Date: Current date only.

Explanation of both of these functions from here.

I am running on FreeBSD 11.1, the freebsd jail virtualization concept makes the operating system optimal. The current version of Git I am using is 2.15.1, I also prefer to run everything on shell scripts. With that in mind I modified the suggestions above as followed:

git push: .git/hooks/pre-commit

#! /bin/sh -
#
# A hook script called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if it wants
# to stop the commit.

SELF_DIR=$(git rev-parse --show-toplevel);
DATABASE=$SELF_DIR/.permissions;

# Clear the permissions database file
> $DATABASE;

printf "Backing-up file permissions...\n";

OLDIFS=$IFS;
IFS=$'\n';
for FILE in $(git ls-files);
do
   # Save the permissions of all the files in the index
    printf "%s;%s\n" $FILE $(stat -f "%Lp;%u;%g" $FILE) >> $DATABASE;
done
IFS=$OLDIFS;

# Add the permissions database file to the index
git add $DATABASE;

printf "OK\n";

git pull: .git/hooks/post-merge

#! /bin/sh -

SELF_DIR=$(git rev-parse --show-toplevel);
DATABASE=$SELF_DIR/.permissions;

printf "Restoring file permissions...\n";

OLDIFS=$IFS;
IFS=$'\n';
while read -r LINE || [ -n "$LINE" ];
do
   FILE=$(printf "%s" $LINE | cut -d ";" -f 1);
   PERMISSIONS=$(printf "%s" $LINE | cut -d ";" -f 2);
   USER=$(printf "%s" $LINE | cut -d ";" -f 3);
   GROUP=$(printf "%s" $LINE | cut -d ";" -f 4);

   # Set the file permissions
   chmod $PERMISSIONS $FILE;

   # Set the file owner and groups
   chown $USER:$GROUP $FILE;

done < $DATABASE
IFS=$OLDIFS

pritnf "OK\n";

exit 0;

If for some reason you need to recreate the script the .permissions file output should have the following format:

.gitignore;644;0;0

For a .gitignore file with 644 permissions given to root:wheel

Notice I had to make a few changes to the stat options.

# Retain a map of the Morse code
conversion = {}

# Read map from file, add it to the datastructure
morseCodeFile = file('morseCode.txt')
for line in moreCodeFile:
    conversion[line[0]] = line[2:]
morseCodeFile.close()

# Ask for input from the user
s = raw_input("Please enter string to translate")
# Go over each character, and print it the translation.

there is indeed an xpath contains function it should look something like:

<xsl:for-each select="item">
<xsl:variable name="hhref" select="link" />
<xsl:variable name="pdate" select="pubDate" />
<xsl:if test="not(contains(hhref,'1234'))">
  <li>
    <a href="{$hhref}" title="{$pdate}">
      <xsl:value-of select="title"/>
    </a>
  </li>
</xsl:if>

You can append the text to $0 in awk if it matches the condition:

awk '/^all:/ {$0=$0" anotherthing"} 1' file

Explanation

• /patt/ {...} if the line matches the pattern given by patt, then perform the actions described within {}.
• In this case: /^all:/ {$0=$0" anotherthing"} if the line starts (represented by ^) with all:, then append anotherthing to the line.
• 1 as a true condition, triggers the default action of awk: print the current line (print $0). This will happen always, so it will either print the original line or the modified one.

Test

For your given input it returns:

somestuff...
all: thing otherthing anotherthing
some other stuff

Note you could also provide the text to append in a variable:

$ awk -v mytext=" EXTRA TEXT" '/^all:/ {$0=$0mytext} 1' file
somestuff...
all: thing otherthing EXTRA TEXT
some other stuff

I'm using moment in my react project

import moment from 'moment'

state = {
    startDate: moment()
};
render() {
    const selectedDate = this.state.startDate.format("Do MMMM YYYY");
    return(
     <Fragment>
       {selectedDate)
     </Fragment>
   );
}

categories_posts and categories_news start with substring 'categories_' then it is enough to check that developer_configurations_cms.cfg_name_unique starts with 'categories' instead of check if it contains the given substring. Translating all that into a query:

SELECT *
    FROM developer_configurations_cms

    WHERE developer_configurations_cms.cat_id = '1'
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
    AND developer_configurations_cms.cfg_name_unique NOT LIKE 'categories%'

FOR A ONE LINER SOLUTION, type the following in Command prompt or Terminal at project root.

echo node_modules > .dockerignore

This creates the extension-less . prefixed file without any issue. Replace node_modules with the folder you want to exclude.

Since you are using .Result or .Wait or await this will end up causing a deadlock in your code.

you can use ConfigureAwait(false) in async methods for preventing deadlock

like this:

var result = await httpClient.GetAsync("http://stackoverflow.com", HttpCompletionOption.ResponseHeadersRead)
                             .ConfigureAwait(false);

you can use ConfigureAwait(false) wherever possible for Don't Block Async Code .

If you care about reading that will always return the objects in the order they are inserted in a Dictionary, you may have a look at

OrderedDictionary - values can be accessed via an integer index (by order in which items were added) SortedDictionary - items are automatically sorted

1. Move the cursor to the n in name.
2. Enter visual block mode (Ctrlv).
3. Press j three times (or 3j).
4. Press I (capital i).
5. Type in vendor_. Note: It will only update the screen in the first line - until Esc is pressed (6.), at which point all lines will be updated.
6. Press Esc.

An uppercase I must be used rather than a lowercase i, because the lowercase i is interpreted as the start of a text object, which is rather useful on its own, e.g. for selecting inside a tag block (it):

Not sure it stands for anything special. It's just a convention that you supply an 'all' rule, and generally it's used to list all the sub-targets needed to build the entire project, hence the name 'all'. The only thing special about it is that often times people will put it in as the first target in the makefile, which means that just typing 'make' alone will do the same thing as 'make all'.

An easy Method, Full control over 'from type' and 'to type', and only need to remember this code for future castings

DateTime.ParseExact(InputDate, "dd/MM/yyyy", CultureInfo.InvariantCulture).ToString("yyyy/MM/dd"));

After t.thielemans' answer, I worked that just

=VLOOKUP(A1, B:C, 2, FALSE) 

works fine and does what I wanted, except that it returns #N/A for non-matches; so it is suitable for the case where it is known that the value definitely exists in the look-up column.

Edit (based on t.thielemans' comment):

To avoid #N/A for non-matches, do:

=IFERROR(VLOOKUP(A1, B:C, 2, FALSE), "No Match")

{
    "files.useExperimentalFileWatcher" : true
}

in Code -> Preferences -> Settings

Tested with Visual Studio Code Version 1.26.1 on mac and win

Call it like this:

foo(*ob);

Note that there is no casting going on here, as suggested in your question title. All we have done is de-referenced the pointer to the object which we then pass to the function.

Extending the Quote idea for Objective-C:

#define NSStringMultiline(...) [[NSString alloc] initWithCString:#__VA_ARGS__ encoding:NSUTF8StringEncoding]

NSString *sql = NSStringMultiline(
    SELECT name, age
    FROM users
    WHERE loggedin = true
);

Another solution would be as below where the list is placed under a drop-down button.

  <button class="btn dropdown-toggle btn-primary btn-sm" data-toggle="dropdown"
    >Markets<span class="caret"></span></button>

    <ul class="dropdown-menu", style="height:40%; overflow:hidden; overflow-y:scroll;">
      {{ form.markets }}
    </ul>

Not done this yet myself, but a quick bit of Google-Fu reveals a tech tip on blogs.oracle.com with examples of exactly what you ask for.

Example taken from the blog post:

MultivaluedMap formData = new MultivaluedMapImpl();
formData.add("name1", "val1");
formData.add("name2", "val2");
ClientResponse response = webResource
    .type(MediaType.APPLICATION_FORM_URLENCODED_TYPE)
    .post(ClientResponse.class, formData);

That any help?

In theory, according to RFC 4329, application/javascript.

The reason it is supposed to be application is not anything to do with whether the type is readable or executable. It's because there are custom charset-determination mechanisms laid down by the language/type itself, rather than just the generic charset parameter. A subtype of text should be capable of being transcoded by a proxy to another charset, changing the charset parameter. This is not true of JavaScript because:

a. the RFC says user-agents should be doing BOM-sniffing on the script to determine type (I'm not sure if any browsers actually do this though);

b. browsers use other information—the including page's encoding and in some browsers the script charset attribute—to determine the charset. So any proxy that tried to transcode the resource would break its users. (Of course in reality no-one ever uses transcoding proxies anyway, but that was the intent.)

Therefore the exact bytes of the file must be preserved exactly, which makes it a binary application type and not technically character-based text.

For the same reason, application/xml is officially preferred over text/xml: XML has its own in-band charset signalling mechanisms. And everyone ignores application for XML, too.

text/javascript and text/xml may not be the official Right Thing, but there are what everyone uses today for compatibility reasons, and the reasons why they're not the right thing are practically speaking completely unimportant.

To handle One-To-Many relationships in Django you need to use ForeignKey.

The documentation on ForeignKey is very comprehensive and should answer all the questions you have:

https://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey

The current structure in your example allows each Dude to have one number, and each number to belong to multiple Dudes (same with Business).

If you want the reverse relationship, you would need to add two ForeignKey fields to your PhoneNumber model, one to Dude and one to Business. This would allow each number to belong to either one Dude or one Business, and have Dudes and Businesses able to own multiple Numbers. I think this might be what you are after.

class Business(models.Model):
    ...
class Dude(models.Model):
    ...
class PhoneNumber(models.Model):
    dude = models.ForeignKey(Dude)
    business = models.ForeignKey(Business)

Use scikit-learn:

from sklearn.preprocessing import MinMaxScaler
data = np.array([1,2,3]).reshape(-1, 1)
scaler = MinMaxScaler()
scaler.fit(data)
print(scaler.transform(data))

You might try running the script through JSLint.

In /config/environments/production.rb I had to add this:

Rails.application.config.assets.precompile += %w( *.js ^[^_]*.css *.css.erb )

The .js was getting precompiled already, but I added it anyway. The .css and .css.erb apparently don't happen automatically. The ^[^_] excludes partials from being compiled -- it's a regexp.

It's a little frustrating that the docs clearly state that asset pipeline IS enabled by default but doesn't clarify the fact that only applies to javascripts.

class of my button is "input-addon btn btn-default fileinput-exists"

below code helped me

document.querySelector('.input-addon.btn.btn-default.fileinput-exists').click();

but I want to click second button, I have two buttons in my screen so I used querySelectorAll

var elem = document.querySelectorAll('.input-addon.btn.btn-default.fileinput-exists');
                elem[1].click();

here elem[1] is the second button object that I want to click.

You can also sometimes get this error if you try to decrypt a secret while su-ed to a different user on a system with GPG 2.x installed. This bug has been reported against RHEL 6 but there is no fix available; apparently this is due to some design decisions in GPG 2.x. One workaround suggested in the bug report is to run the decryption inside of a tmux or screen session. More reading here.

I found this perfect solution and may useful, You can directly get in format as you want:

Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, -90); // I just want date before 90 days. you can give that you want.

SimpleDateFormat s = new SimpleDateFormat("yyyy-MM-dd"); // you can specify your format here...
Log.d("DATE","Date before 90 Days: " + s.format(new Date(cal.getTimeInMillis())));

Thanks.

For future Googlers, If you get an error similar below after you trigger click for a polygon

"Uncaught TypeError: Cannot read property 'vertex' of undefined"

then try the code below

google.maps.event.trigger(polygon, "click", {});

With this solution you can fully enable/disable the security by activating a specific profile by command line. I defined the profile in a file application-nosecurity.yaml

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Then I modified my custom WebSecurityConfigurerAdapter by adding the @Profile("!nosecurity") as follows:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
@Profile("!nosecurity")
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {...}

To fully disable the security it's enough to start the application up by specifying the nosecurity profile, i.e.:

java -jar  target/myApp.jar --spring.profiles.active=nosecurity

The original poster has likely long moved on, but I took a stab at porting the Perl Geo::StreetAddress:US module used by geocoder.us to C#, dumped it on CodePlex, and think that people stumbling across this question in the future may find it useful:

US Address Parser

On the project's home page, I try to talk about its (very real) limitations. Since it is not backed by the USPS database of valid street addresses, parsing can be ambiguous and it can't confirm nor deny the validity of a given address. It can just try to pull data out from the string.

It's meant for the case when you need to get a set of data mostly in the right fields, or want to provide a shortcut to data entry (letting users paste an address into a textbox rather than tabbing among multiple fields). It is not meant for verifying the deliverability of an address.

It doesn't attempt to parse out anything above the street line, but one could probably diddle with the regex to get something reasonably close--I'd probably just break it off at the house number.

var dt = new Date();
    var h =  dt.getHours(), m = dt.getMinutes();
    var thistime = (h > 12) ? (h-12 + ':' + m +' PM') : (h + ':' + m +' AM');
console.log(thistime);

Here is the Demo

<properties>
  <!-- Use the latest version whenever possible. -->
  <jackson.version>2.4.4</jackson.version>
</properties>
<dependencies>
   <dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${jackson.version}</version>
  </dependency>
</dependencies>

you have a ObjectMapper (from Jackson Databind package) handy. if so, you can do:

JsonFactory factory = objectMapper.getFactory();

Source: https://github.com/FasterXML/jackson-core

So, the 3 "fasterxml" dependencies which you already have in u'r pom are enough for ObjectMapper as it includes jackson-databind.

You can use the back button callback, like this:

- (BOOL) navigationShouldPopOnBackButton
{
    [self backAction];
    return NO;
}

- (void) backAction {
    // your code goes here
    // show confirmation alert, for example
    // ...
}

for swift version you can do something like in global scope

extension UIViewController {
     @objc func navigationShouldPopOnBackButton() -> Bool {
     return true
    }
}

extension UINavigationController: UINavigationBarDelegate {
     public func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
          return self.topViewController?.navigationShouldPopOnBackButton() ?? true
    }
}

Below one you put in the viewcontroller where you want to control back button action:

override func navigationShouldPopOnBackButton() -> Bool {
    self.backAction()//Your action you want to perform.

    return true
}

The > and < are transitive properties, so if a > b and b > c, then a > c. So you can

int a=10, b=6, c=4, d=21, e=4;

int maxNum = a;
int maxNum = max(b, maxNum);
int maxNum = max(c, maxNum);
int maxNum = max(d, maxNum);
int maxNum = max(e, maxNum);

If you only have one camera, or you don't care which camera is the correct one, then use "-1" as the index. Ie for your example capture = cv.CaptureFromCAM(-1).

You can get the example of css implemented html to pdf conversion using jspdf on following link: JSFiddle Link

This is sample code for the jspdf html to pdf download.

$('#print-btn').click(() => {
    var pdf = new jsPDF('p','pt','a4');
    pdf.addHTML(document.body,function() {
        pdf.save('web.pdf');
    });
})

You can use yourstring.split("\x09"); I tested it, and it works.

I needed to copy all .md files from one directory into another, so here is what I did.

for i in **/*.md;do mkdir -p ../docs/"$i" && rm -r ../docs/"$i" && cp "$i" "../docs/$i" && echo "$i -> ../docs/$i"; done

Which is pretty hard to read, so lets break it down.

first cd into the directory with your files,

for i in **/*.md; for each file in your pattern

mkdir -p ../docs/"$i"make that directory in a docs folder outside of folder containing your files. Which creates an extra folder with the same name as that file.

rm -r ../docs/"$i" remove the extra folder that is created as a result of mkdir -p

cp "$i" "../docs/$i" Copy the actual file

echo "$i -> ../docs/$i" Echo what you did

; done Live happily ever after

This is how did it works like a charm.

1. Install request module, using npm install request

2. In code:

   var request = require('request');
   var data = '{ "request" : "msg", "data:" {"key1":' + Var1 + ', "key2":' + Var2 + '}}';
   var json_obj = JSON.parse(data);
   request.post({
       headers: {'content-type': 'application/json'},
       url: 'http://localhost/PhpPage.php',
       form: json_obj
   }, function(error, response, body){
     console.log(body)
   });
   

Instead of calling /usr/bin/gcc, use /usr/bin/c99. This is the Single-Unix-approved way of invoking a C99 compiler. On an Ubuntu system, this points to a script which invokes gcc after having added the -std=c99 flag, which is precisely what you want.

=IFERROR(LEFT(A3, FIND(" ", A3, 1)), A3)

This will firstly check if the cell contains a space, if it does it will return the first value from the space, otherwise it will return the cell value.

Edit

Just to add to the above formula, as it stands if there is no value in the cell it would return 0. If you are looking to display a message or something to tell the user it is empty you could use the following:

=IF(IFERROR(LEFT(A3, FIND(" ", A3, 1)), A3)=0, "Empty", IFERROR(LEFT(A3, FIND(" ", A3, 1)), A3))

If you only want to change the route for picture.php then adding rewrite rule in .htaccess will serve your needs, but, if you want the URL rewriting as in Wordpress then PHP is the way. Here is simple example to begin with.

Folder structure

There are two files that are needed in the root folder, .htaccess and index.php, and it would be good to place the rest of the .php files in separate folder, like inc/.

root/
  inc/
  .htaccess
  index.php

.htaccess

RewriteEngine On
RewriteRule ^inc/.*$ index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]

This file has four directives:

1. RewriteEngine - enable the rewriting engine
2. RewriteRule - deny access to all files in inc/ folder, redirect any call to that folder to index.php
3. RewriteCond - allow direct access to all other files ( like images, css or scripts )
4. RewriteRule - redirect anything else to index.php

index.php

Because everything is now redirected to index.php, there will be determined if the url is correct, all parameters are present, and if the type of parameters are correct.

To test the url we need to have a set of rules, and the best tool for that is a regular expression. By using regular expressions we will kill two flies with one blow. Url, to pass this test must have all the required parameters that are tested on allowed characters. Here are some examples of rules.

$rules = array( 
    'picture'   => "/picture/(?'text'[^/]+)/(?'id'\d+)",    // '/picture/some-text/51'
    'album'     => "/album/(?'album'[\w\-]+)",              // '/album/album-slug'
    'category'  => "/category/(?'category'[\w\-]+)",        // '/category/category-slug'
    'page'      => "/page/(?'page'about|contact)",          // '/page/about', '/page/contact'
    'post'      => "/(?'post'[\w\-]+)",                     // '/post-slug'
    'home'      => "/"                                      // '/'
);

Next is to prepare the request uri.

$uri = rtrim( dirname($_SERVER["SCRIPT_NAME"]), '/' );
$uri = '/' . trim( str_replace( $uri, '', $_SERVER['REQUEST_URI'] ), '/' );
$uri = urldecode( $uri );

Now that we have the request uri, the final step is to test uri on regular expression rules.

foreach ( $rules as $action => $rule ) {
    if ( preg_match( '~^'.$rule.'$~i', $uri, $params ) ) {
        /* now you know the action and parameters so you can 
         * include appropriate template file ( or proceed in some other way )
         */
    }
}

Successful match will, since we use named subpatterns in regex, fill the $params array almost the same as PHP fills the $_GET array. However, when using a dynamic url, $_GET array is populated without any checks of the parameters.

    /picture/some+text/51

    Array
    (
        [0] => /picture/some text/51
        [text] => some text
        [1] => some text
        [id] => 51
        [2] => 51
    )

    picture.php?text=some+text&id=51

    Array
    (
        [text] => some text
        [id] => 51
    )

These few lines of code and a basic knowing of regular expressions is enough to start building a solid routing system.

Complete source

define( 'INCLUDE_DIR', dirname( __FILE__ ) . '/inc/' );

$rules = array( 
    'picture'   => "/picture/(?'text'[^/]+)/(?'id'\d+)",    // '/picture/some-text/51'
    'album'     => "/album/(?'album'[\w\-]+)",              // '/album/album-slug'
    'category'  => "/category/(?'category'[\w\-]+)",        // '/category/category-slug'
    'page'      => "/page/(?'page'about|contact)",          // '/page/about', '/page/contact'
    'post'      => "/(?'post'[\w\-]+)",                     // '/post-slug'
    'home'      => "/"                                      // '/'

    if ( preg_match( '~^'.$rule.'$~i', $uri, $params ) ) {
        /* now you know the action and parameters so you can 
         * include appropriate template file ( or proceed in some other way )
         */
        include( INCLUDE_DIR . $action . '.php' );

        // exit to avoid the 404 message 
        exit();
    }
}

// nothing is found so handle the 404 error
include( INCLUDE_DIR . '404.php' );

ip = InetAddress.getByAddress(new byte[] {
        (byte)192, (byte)168, (byte)0, (byte)102}

To catch errors with subprocess.check_output(), you can use CalledProcessError. If you want to use the output as string, decode it from the bytecode.

# \return String of the output, stripped from whitespace at right side; or None on failure.
def runls():
    import subprocess
    try:
        byteOutput = subprocess.check_output(['ls', '-a'], timeout=2)
        return byteOutput.decode('UTF-8').rstrip()
    except subprocess.CalledProcessError as e:
        print("Error in ls -a:\n", e.output)
        return None

You can do something like this

   SELECT IFNULL(`price`.`fPrice`,100) as fPrice,product.ProductId,ProductName 
          FROM `products` left join `price` ON 
          price.ProductId=product.ProductId AND (GeoFancingId=1 OR GeoFancingId 
          IS NULL) WHERE Status="Active" AND Delete="No"

I provide another answer that I found by api-client-library by Google

try {
    DateTime dateTime = DateTime.parseRfc3339(date);
    dateTime = new DateTime(new Date(dateTime.getValue()), TimeZone.getDefault());
    long timestamp = dateTime.getValue();  // get date in timestamp
    int timeZone = dateTime.getTimeZoneShift();  // get timezone offset
} catch (NumberFormatException e) {
    e.printStackTrace();
}

Here's the query example to check the existence of multiple fields:

{
  "query": {
    "bool": {
      "filter": [
        {
          "exists": {
            "field": "field_1"
          }
        },
        {
          "exists": {
            "field": "field_2"
          }
        },
        {
          "exists": {
            "field": "field_n"
          }
        }
      ]
    }
  }
}

In .NET 5.0 and later you can use the Convert.ToHexString() method.

using System;
using System.Text;

string value = "Hello world";

byte[] bytes = Encoding.UTF8.GetBytes(value);

string hexString = Convert.ToHexString(bytes);

Console.WriteLine($"String value: \"{value}\"");
Console.WriteLine($"   Hex value: \"{hexString}\"");

Running the above example code, you would get the following output:

String value: "Hello world"
   Hex value: "48656C6C6F20776F726C64"

If you have a Linux-Machine you could use the free command-line tool SAXCount. I found this very usefull.

SAXCount -f -s -n my.xml

It validates against dtd and xsd. 5s for a 50MB file.

In debian squeeze it is located in the package "libxerces-c-samples".

The definition of the dtd and xsd has to be in the xml! You can't config them separately.

The answers above are still using the old Python 3.4 style coroutines. Here is what you would write if you got Python 3.5+.

aiohttp supports http proxy now

import aiohttp
import asyncio

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    urls = [
            'http://python.org',
            'https://google.com',
            'http://yifei.me'
        ]
    tasks = []
    async with aiohttp.ClientSession() as session:
        for url in urls:
            tasks.append(fetch(session, url))
        htmls = await asyncio.gather(*tasks)
        for html in htmls:
            print(html[:100])

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Java implementation contains utilities classes java.util.Arrays and java.util.Collections both of them contains static factory methods, examples of it and how to use :

• Arrays.asList("1","2","3")

• Collections.synchronizedList(..), Collections.emptyList(), Collections.unmodifiableList(...) (Only some examples, could check javadocs for mor methods examples https://docs.oracle.com/javase/8/docs/api/java/util/Collections.html)

Also java.lang.String class have such static factory methods:

• String.format(...), String.valueOf(..), String.copyValueOf(...)

var btn = document.getElementById('btn-test');
var event = new Event(null);

event.initEvent('beforeinstallprompt', true, true);
btn.addEventListener('beforeinstallprompt', null, false);
btn.dispatchEvent(event);

this will imediattely trigger an event 'beforeinstallprompt'

This solutions works fine for me.

utils/newid.js:

let lastId = 0;

export default function(prefix='id') {
    lastId++;
    return `${prefix}${lastId}`;
}

And I can use it like this:

import newId from '../utils/newid';

React.createClass({
    componentWillMount() {
        this.id = newId();
    },
    render() {
        return (
            <label htmlFor={this.id}>My label</label>
            <input id={this.id} type="text"/>
        );
    }
});

But it won’t work in isomorphic apps.

Added 17.08.2015. Instead of custom newId function you can use uniqueId from lodash.

Updated 28.01.2016. It’s better to generate ID in componentWillMount.

You've tried alot. And I feel for you. Here is an idea. I kinda followed everything you tried. The mental note I have in my head goes like this: "When Sql Server won't connect when you've tried everything, wire up your firewall rules by the program, not the port"

I know you said you disabled the firewall. But something is telling me to give this a try anyways.

I think you have to open the firewall "by program", and not by port.

http://technet.microsoft.com/en-us/library/cc646023.aspx

To add a program exception to the firewall using the Windows Firewall item in Control Panel.


On the Exceptions tab of the Windows Firewall item in Control Panel, click Add a program.


Browse to the location of the instance of SQL Server that you want to allow through the firewall, for example C:\Program Files\Microsoft SQL Server\MSSQL11.<instance_name>\MSSQL\Binn, select sqlservr.exe, and then click Open.


 Click OK.

EDIT..........

http://msdn.microsoft.com/en-us/library/ms190479.aspx

I'm a little cloudy on which "program" you're trying to use on SQLB?

Is it SSMS on SQLB? Or a client program on SQLB ?

EDIT...........

No idea if this will help. But I use this to ping "ports" ... and something that is outside of the SSMS world.

You can count how many digits you want to print first

#include <iostream>
#include <cmath>
using namespace std;

int main(){
int number, result, counter=0, zeros;

do{
    cout << "Introduce un numero entero: ";
  cin >> number;

  }while (number < 0);

  // We count how many digits we are going print
  for(int i = number; i > 0; i = i/10)
        counter++;

   while(number > 0){

       zeros = pow(10, counter - 1);

       result = number / zeros;
       number = number % zeros;
       counter--;

       //Muestra resultados
       cout << " " << result;
   }
   cout<<endl;

}

My case is the page is sending multiple requests with different parameters when it was open. So most are being "stalled". Following requests immediately sent gets "stalled". Avoiding unnecessary requests would be better (to be lazy...).

Two things you can do here:

1. Read Painting in AWT and Swing
2. Use a debugger and put a breakpoint in the paintComponent method. Then travel up the stacktrace and see how provides the Graphics parameter.

Just for info, here is the stacktrace that I got from the example of code I posted at the end:

The Graphics parameter comes from here:

RepaintManager.paintDirtyRegions(Map) line: 781 

The snippet involved is the following:

Graphics g = JComponent.safelyGetGraphics(
                        dirtyComponent, dirtyComponent);
                // If the Graphics goes away, it means someone disposed of
                // the window, don't do anything.
                if (g != null) {
                    g.setClip(rect.x, rect.y, rect.width, rect.height);
                    try {
                        dirtyComponent.paint(g); // This will eventually call paintComponent()
                    } finally {
                        g.dispose();
                    }
                }

If you take a look at it, you will see that it retrieve the graphics from the JComponent itself (indirectly with javax.swing.JComponent.safelyGetGraphics(Component, Component)) which itself takes it eventually from its first "Heavyweight parent" (clipped to the component bounds) which it self takes it from its corresponding native resource.

Regarding the fact that you have to cast the Graphics to a Graphics2D, it just happens that when working with the Window Toolkit, the Graphics actually extends Graphics2D, yet you could use other Graphics which do "not have to" extends Graphics2D (it does not happen very often but AWT/Swing allows you to do that).

import java.awt.Color;
import java.awt.Graphics;

import javax.swing.JFrame;
import javax.swing.JPanel;

class TestPaint extends JPanel {

    public TestPaint() {
        setBackground(Color.WHITE);
    }

    @Override
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawOval(0, 0, getWidth(), getHeight());
    }

    public static void main(String[] args) {
        JFrame jFrame = new JFrame();
        jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        jFrame.setSize(300, 300);
        jFrame.add(new TestPaint());
        jFrame.setVisible(true);
    }
}

This might be seen as a little complex but does exactly what you want

SELECT 
  DISTINCT(p.`ProductID`) AS ProductID,
  SUM(pl.CashAmount) AS Cash,
  SUM(pr.CashAmount) AS `Check`,
  SUM(px.CashAmount) AS `Credit Card`,
  SUM(pl.CashAmount) + SUM(pr.CashAmount) +SUM(px.CashAmount) AS Amount
FROM
  `payments` AS p 
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Cash' GROUP BY ProductID , PaymentMethod ) AS pl 
    ON pl.`PaymentMethod` = p.`PaymentMethod` AND pl.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Check' GROUP BY ProductID , PaymentMethod) AS pr 
    ON pr.`PaymentMethod` = p.`PaymentMethod` AND pr.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID, PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Credit Card' GROUP BY ProductID , PaymentMethod) AS px 
    ON px.`PaymentMethod` = p.`PaymentMethod` AND px.ProductID = p.`ProductID`
GROUP BY p.`ProductID` ;

Output

ProductID | Cash | Check | Credit Card | Amount
-----------------------------------------------
    3     | 20   |  15   |   25        |  60
    4     | 5    |  6    |   7         |  18
