I'm working on Windows 10 with Anaconda 3.6.5. I have not admin rights, so if someone is under the circumstances like me this solution works perfectly.

The path for my graphviz is looks C:\Users\User_Name\AppData\Local\Continuum\anaconda3\Library\bin\graphviz

In Spyder or in Jupyter type the following:

import os os.environ['PATH'].split(os.pathsep) This will lists all the path in you environment. Take a look to them, if your graphviz path is not here, then go find it and copy the path, like above in my example. Then type the following: os.environ['PATH'] += os.pathsep + 'C:\\Users\\User_Name\\AppData\\Local\\Continuum\\anaconda3\\Library\\bin\\graphviz'

That's all, but note that you have to run these command every time if you restart kernel

To solve this problem,when you install graphviz2.38 successfully, then add your PATH variable to system path.Under System Variables you can click on Path and then clicked Edit and added ;C:\Program Files (x86)\Graphviz2.38\bin to the end of the string and saved.After that,restart your pythonIDE like spyper,then it works well.

Don't forget to close Spyder and then restart.

I had a similar issue after upgrading from PHP 5.5 to PHP 5.6. The phpize and php-config libraries being used to compile the phalcon extension were still the ones from PHP 5.5. I had to run the command below:

sudo apt-get install php5.6-dev

There will be a long stacktrace, the key information I saw was this:

update-alternatives: using /usr/bin/php-config5.6 to provide /usr/bin/php-config (php-config) in auto mode
update-alternatives: using /usr/bin/phpize5.6 to provide /usr/bin/phpize (phpize) in auto mode

I hope this helps someone.

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack), you just need to find an output of the hash function that is equal to the hash of a valid password (thus "collision"). Finding a collision using a birthday attack takes O(2^(n/2)) time, where n is the output length of the hash function in bits.

SHA-2 has an output size of 512 bits, so finding a collision would take O(2^256) time. Given there are no clever attacks on the algorithm itself (currently none are known for the SHA-2 hash family) this is what it takes to break the algorithm.

To get a feeling for what 2^256 actually means: currently it is believed that the number of atoms in the (entire!!!) universe is roughly 10^80 which is roughly 2^266. Assuming 32 byte input (which is reasonable for your case - 20 bytes salt + 12 bytes password) my machine takes ~0,22s (~2^-2s) for 65536 (=2^16) computations. So 2^256 computations would be done in 2^240 * 2^16 computations which would take

2^240 * 2^-2 = 2^238 ~ 10^72s ~ 3,17 * 10^64 years

Even calling this millions of years is ridiculous. And it doesn't get much better with the fastest hardware on the planet computing thousands of hashes in parallel. No human technology will be able to crunch this number into something acceptable.

So forget brute-forcing SHA-256 here. Your next question was about dictionary words. To retrieve such weak passwords rainbow tables were used traditionally. A rainbow table is generally just a table of precomputed hash values, the idea is if you were able to precompute and store every possible hash along with its input, then it would take you O(1) to look up a given hash and retrieve a valid preimage for it. Of course this is not possible in practice since there's no storage device that could store such enormous amounts of data. This dilemma is known as memory-time tradeoff. As you are only able to store so many values typical rainbow tables include some form of hash chaining with intermediary reduction functions (this is explained in detail in the Wikipedia article) to save on space by giving up a bit of savings in time.

Salts were a countermeasure to make such rainbow tables infeasible. To discourage attackers from precomputing a table for a specific salt it is recommended to apply per-user salt values. However, since users do not use secure, completely random passwords, it is still surprising how successful you can get if the salt is known and you just iterate over a large dictionary of common passwords in a simple trial and error scheme. The relationship between natural language and randomness is expressed as entropy. Typical password choices are generally of low entropy, whereas completely random values would contain a maximum of entropy.

The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords. If you google for them, you will end up finding torrent links for such password databases, often in the gigabyte size category. Being successful with such a tool is usually in the range of minutes to days if the attacker is not restricted in any way.

That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5 and you should enforce a waiting period for a given user before they may retry entering their password. A good scheme is to start with 0.5s and then doubling that time for each failed attempt. In most cases users don't notice this and don't fail much more often than three times on average. But it will significantly slow down any malicious outsider trying to attack your application.

perhaps this is what you're looking for: https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/colors.xml

If you don't want to SELECT SLEEP(1);, you can also DO SLEEP(1); It's useful for those situations in procedures where you don't want to see output.

e.g.

SELECT ...
DO SLEEP(5);
SELECT ...

Eclipse C/C++ does not recognize the symbol std::unique_ptr even though you have included the C++11 memory header in your file.

Assuming you are using the GNU C++ compiler, this is what I did to fix:

Project -> Properties -> C/C++ General -> Preprocessor Include Paths -> GNU C++ -> CDT User Setting Entries

1. Click on the "Add..." button

2. Select "Preprocessor Macro" from the dropdown menu

   Name: __cplusplus     Value:  201103L
   

3. Hit Apply, and then OK to go back to your project

4. Then rebuild you C++ index: Projects -> C/C++ Index -> Rebuild

CSS:

.reverse {
  transform: rotate(180deg);
}

.rotate {
  animation-duration: .5s;
  animation-iteration-count: 1;
  animation-name: yoyo;
  animation-timing-function: linear;
}

@keyframes yoyo {
  from { transform: rotate(  0deg); }
  to   { transform: rotate(360deg); }
}

Javascript:

$(buttonElement).click(function () {
  $(".arrow").toggleClass("reverse")

  return false
})

$(buttonElement).hover(function () {
  $(".arrow").addClass("rotate")
}, function() {
  $(".arrow").removeClass("rotate")
})

Save your file with different encoding:

File > Save file as... > Save as UTF-8 without signature.

In VS 2017 you find encoding as a dropdown next to Save button.

Everyone tries Application.Wait, but that's not really reliable. If you ask it to wait for less than a second, you'll get anything between 0 and 1, but closer to 10 seconds. Here's a demonstration using a wait of 0.5 seconds:

Sub TestWait()
  Dim i As Long
  For i = 1 To 5
    Dim t As Double
    t = Timer
    Application.Wait Now + TimeValue("0:00:00") / 2
    Debug.Print Timer - t
  Next
End Sub

Here's the output, an average of 0.0015625 seconds:

0
0
0
0.0078125
0

Admittedly, Timer may not be the ideal way to measure these events, but you get the idea.

The Timer approach is better:

Sub TestTimer()
  Dim i As Long
  For i = 1 To 5
    Dim t As Double
    t = Timer
    Do Until Timer - t >= 0.5
      DoEvents
    Loop
    Debug.Print Timer - t
  Next
End Sub

And the results average is very close to 0.5 seconds:

0.5
0.5
0.5
0.5
0.5

RESTful Resource controller

A RESTful resource controller sets up some default routes for you and even names them.

Route::resource('users', 'UsersController');

Gives you these named routes:

Verb          Path                        Action  Route Name
GET           /users                      index   users.index
GET           /users/create               create  users.create
POST          /users                      store   users.store
GET           /users/{user}               show    users.show
GET           /users/{user}/edit          edit    users.edit
PUT|PATCH     /users/{user}               update  users.update
DELETE        /users/{user}               destroy users.destroy

And you would set up your controller something like this (actions = methods)

class UsersController extends BaseController {

    public function index() {}

    public function show($id) {}

    public function store() {}

}

You can also choose what actions are included or excluded like this:

Route::resource('users', 'UsersController', [
    'only' => ['index', 'show']
]);

Route::resource('monkeys', 'MonkeysController', [
    'except' => ['edit', 'create']
]);

API Resource controller

Laravel 5.5 added another method for dealing with routes for resource controllers. API Resource Controller acts exactly like shown above, but does not register create and edit routes. It is meant to be used for ease of mapping routes used in RESTful APIs - where you typically do not have any kind of data located in create nor edit methods.

Route::apiResource('users', 'UsersController');

RESTful Resource Controller documentation

Implicit controller

An Implicit controller is more flexible. You get routed to your controller methods based on the HTTP request type and name. However, you don't have route names defined for you and it will catch all subfolders for the same route.

Route::controller('users', 'UserController');

Would lead you to set up the controller with a sort of RESTful naming scheme:

class UserController extends BaseController {

    public function getIndex()
    {
        // GET request to index
    }

    public function getShow($id)
    {
        // get request to 'users/show/{id}'
    }

    public function postStore()
    {
        // POST request to 'users/store'
    }

}

Implicit Controller documentation

It is good practice to use what you need, as per your preference. I personally don't like the Implicit controllers, because they can be messy, don't provide names and can be confusing when using php artisan routes. I typically use RESTful Resource controllers in combination with explicit routes.

Straight from the horse's moutyh: Summary of Product Advertising API Operations which has the following categories:

• Find Items
• Find Out More About Specific Items
• Shopping Cart
• Customer Content
• Seller Information
• Other Operations

I can recommend ArcadiaCharts. A brand-new professional charting library for JavaScript and GWT. Runs in all browsers without plugins. Easy and fast to use: creates great looking charts with just a few lines of code. Free for non-commercial use.

You can simply use pkill -f like this:

pkill -f 'java -jar'

EDIT: To kill a particular java process running your specific jar use this regex based pkill command:

pkill -f 'java.*lnwskInterface'

The optional SECOND argument is the index, starting at 0. So to output the index and total length of an array called 'some_list':

<div>Total Length: {{some_list.length}}</div>
<div v-for="(each, i) in some_list">
  {{i + 1}} : {{each}}
</div>

If instead of a list, you were looping through an object, then the second argument is key of the key/value pair. So for the object 'my_object':

var an_id = new Vue({
  el: '#an_id',
  data: {
    my_object: {
        one: 'valueA',
        two: 'valueB'
    }
  }
})

The following would print out the key : value pairs. (you can name 'each' and 'i' whatever you want)

<div id="an_id">
  <span v-for="(each, i) in my_object">
    {{i}} : {{each}}<br/>
  </span>
</div>

This worked for me (I'm using Manjaro linux). I run the cmd to view ca-certificates:

$ curl-config --ca
**/etc/ssl/certs/ca-certificates.crt**

But actually i found the certificates at the path:

**/etc/ca-certificates/extracted/ca-bundle.trust.crt**

Then add the config into ~/.gitconfig (if not existing, create it):

**vim ~/.gitconfig**
[http]
    sslVerify = true
    sslCAinfo = /etc/ca-certificates/extracted/ca-bundle.trust.crt

[user]
    email = <email of github account>
    name = <username of github account>

It works!

I'm assuming this is an action that you want to be performed at most one time, if some conditions are met. Since you won't always perform the action, you can't do it unconditionally outside the loop. Something like lazily retrieving some data (and caching it) if you get a request, but not retrieving it otherwise.

def do_something():
    [x() for x in expensive_operations]
    global action
    action = lambda : None

action = do_something
while True:
    # some sort of complex logic...
    if foo:
        action()

The JPanel is actually only a container where you can put different elements in it (even other JPanels). So in your case I would suggest one big JPanel as some sort of main container for your window. That main panel you assign a Layout that suits your needs ( here is an introduction to the layouts).

After you set the layout to your main panel you can add the paint panel and the other JPanels you want (like those with the text in it..).

  JPanel mainPanel = new JPanel();
  mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));

  JPanel paintPanel = new JPanel();
  JPanel textPanel = new JPanel();

  mainPanel.add(paintPanel);
  mainPanel.add(textPanel);

This is just an example that sorts all sub panels vertically (Y-Axis). So if you want some other stuff at the bottom of your mainPanel (maybe some icons or buttons) that should be organized with another layout (like a horizontal layout), just create again a new JPanel as a container for all the other stuff and set setLayout(new BoxLayout(mainPanel, BoxLayout.X_AXIS).

As you will find out, the layouts are quite rigid and it may be difficult to find the best layout for your panels. So don't give up, read the introduction (the link above) and look at the pictures – this is how I do it :)

Or you can just use NetBeans to write your program. There you have a pretty easy visual editor (drag and drop) to create all sorts of Windows and Frames. (only understanding the code afterwards is ... tricky sometimes.)

EDIT

Since there are some many people interested in this question, I wanted to provide a complete example of how to layout a JFrame to make it look like OP wants it to.

The class is called MyFrame and extends swings JFrame

public class MyFrame extends javax.swing.JFrame{

    // these are the components we need.
    private final JSplitPane splitPane;  // split the window in top and bottom
    private final JPanel topPanel;       // container panel for the top
    private final JPanel bottomPanel;    // container panel for the bottom
    private final JScrollPane scrollPane; // makes the text scrollable
    private final JTextArea textArea;     // the text
    private final JPanel inputPanel;      // under the text a container for all the input elements
    private final JTextField textField;   // a textField for the text the user inputs
    private final JButton button;         // and a "send" button

    public MyFrame(){

        // first, lets create the containers:
        // the splitPane devides the window in two components (here: top and bottom)
        // users can then move the devider and decide how much of the top component
        // and how much of the bottom component they want to see.
        splitPane = new JSplitPane();

        topPanel = new JPanel();         // our top component
        bottomPanel = new JPanel();      // our bottom component

        // in our bottom panel we want the text area and the input components
        scrollPane = new JScrollPane();  // this scrollPane is used to make the text area scrollable
        textArea = new JTextArea();      // this text area will be put inside the scrollPane

        // the input components will be put in a separate panel
        inputPanel = new JPanel();
        textField = new JTextField();    // first the input field where the user can type his text
        button = new JButton("send");    // and a button at the right, to send the text

        // now lets define the default size of our window and its layout:
        setPreferredSize(new Dimension(400, 400));     // let's open the window with a default size of 400x400 pixels
        // the contentPane is the container that holds all our components
        getContentPane().setLayout(new GridLayout());  // the default GridLayout is like a grid with 1 column and 1 row,
        // we only add one element to the window itself
        getContentPane().add(splitPane);               // due to the GridLayout, our splitPane will now fill the whole window

        // let's configure our splitPane:
        splitPane.setOrientation(JSplitPane.VERTICAL_SPLIT);  // we want it to split the window verticaly
        splitPane.setDividerLocation(200);                    // the initial position of the divider is 200 (our window is 400 pixels high)
        splitPane.setTopComponent(topPanel);                  // at the top we want our "topPanel"
        splitPane.setBottomComponent(bottomPanel);            // and at the bottom we want our "bottomPanel"

        // our topPanel doesn't need anymore for this example. Whatever you want it to contain, you can add it here
        bottomPanel.setLayout(new BoxLayout(bottomPanel, BoxLayout.Y_AXIS)); // BoxLayout.Y_AXIS will arrange the content vertically

        bottomPanel.add(scrollPane);                // first we add the scrollPane to the bottomPanel, so it is at the top
        scrollPane.setViewportView(textArea);       // the scrollPane should make the textArea scrollable, so we define the viewport
        bottomPanel.add(inputPanel);                // then we add the inputPanel to the bottomPanel, so it under the scrollPane / textArea

        // let's set the maximum size of the inputPanel, so it doesn't get too big when the user resizes the window
        inputPanel.setMaximumSize(new Dimension(Integer.MAX_VALUE, 75));     // we set the max height to 75 and the max width to (almost) unlimited
        inputPanel.setLayout(new BoxLayout(inputPanel, BoxLayout.X_AXIS));   // X_Axis will arrange the content horizontally

        inputPanel.add(textField);        // left will be the textField
        inputPanel.add(button);           // and right the "send" button

        pack();   // calling pack() at the end, will ensure that every layout and size we just defined gets applied before the stuff becomes visible
    }

    public static void main(String args[]){
        EventQueue.invokeLater(new Runnable(){
            @Override
            public void run(){
                new MyFrame().setVisible(true);
            }
        });
    }
}

Please be aware that this is only an example and there are multiple approaches to layout a window. It all depends on your needs and if you want the content to be resizable / responsive. Another really good approach would be the GridBagLayout which can handle quite complex layouting, but which is also quite complex to learn.

There is an easy solution by using java FunctionalInterface and then add that interface as dependency for the class you are trying to unit test.

just in case you're facing this problem under windows 10 , add the group of users "youcomputer\Users" on the security Tab and grant it full control , that solved my issue

select a.ip, a.os, a.hostname, a.port, a.protocol,
       b.state
from a
left join b on a.ip = b.ip 
           and a.port = b.port

Wow, you have a huge misunderstanding how asp.net works.

This line of code

System.Diagnostics.Process.Start("help/AdminTutorial.html");

Will not redirect a admin user to a new site, but start a new process on the server (usually a browser, IE) and load the site. That is for sure not what you want.

A very easy solution would be to change the href attribute of the link in you page_load method.

Your aspx code:

<a href="#" runat="server" id="myLink">Tutorial</a>

Your codebehind / cs code of page_load:

...
if (userinfo.user == "Admin")
{
  myLink.Attributes["href"] = "help/AdminTutorial.html";
}
else 
{
  myLink.Attributes["href"] = "help/otherSite.html";
}
...

Don't forget to check the Admin rights again on "AdminTutorial.html" to "prevent" hacking.

I needed something a little more different: display the full sha1 of the commit, but append an asterisk to the end if the working directory is not clean. Unless I wanted to use multiple commands, none of the options in the previous answers work.

Here is the one liner that does:
git describe --always --abbrev=0 --match "NOT A TAG" --dirty="*"
Result: f5366ccb21588c0d7a5f7d9fa1d3f85e9f9d1ffe*

Explanation: describes (using annotated tags) the current commit, but only with tags containing "NOT A TAG". Since tags cannot have spaces, this never matches a tag and since we want to show a result --always, the command falls back displaying the full (--abbrev=0) sha1 of the commit and it appends an asterisk if the working directory is --dirty.

If you don't want to append the asterisk, this works like all the other commands in the previous answers:
git describe --always --abbrev=0 --match "NOT A TAG"
Result: f5366ccb21588c0d7a5f7d9fa1d3f85e9f9d1ffe

Turn if off:

You can use error_reporting(); or put an @ in front of your fileopen().

Here is a log4j.properties file that I've used with great success.

logDir=/var/log/myapp

log4j.rootLogger=INFO, stdout
#log4j.rootLogger=DEBUG, stdout

log4j.appender.stdout=org.apache.log4j.DailyRollingFileAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{MM/dd/yyyy hh:mm:ss a}|%-5p|%-30c{1}| %m%n
log4j.appender.stdout.DatePattern='.'yyyy-MM-dd
log4j.appender.stdout.File=${logDir}/myapp.log
log4j.appender.stdout.append=true

The DailyRollingFileAppender will create new files each day with file names that look like this:

myapp.log.2017-01-27
myapp.log.2017-01-28
myapp.log.2017-01-29
myapp.log  <-- today's log

Each entry in the log file will will have this format:

01/30/2017 12:59:47 AM|INFO |Component1   | calling foobar(): userId=123, returning totalSent=1
01/30/2017 12:59:47 AM|INFO |Component2   | count=1 > 0, calling fooBar()

Set the location of the above file by using -Dlog4j.configuration, as mentioned in this posting:

java -Dlog4j.configuration=file:/home/myapp/config/log4j.properties com.foobar.myapp

In your Java code, be sure to set the name of each software component when you instantiate your logger object. I also like to log to both the log file and standard output, so I wrote this small function.

private static final Logger LOGGER = Logger.getLogger("Component1");

public static void log(org.apache.log4j.Logger logger, String message) {

    logger.info(message);
    System.out.printf("%s\n", message);
}

public static String stackTraceToString(Exception ex) {
    StringWriter sw = new StringWriter();
    PrintWriter pw = new PrintWriter(sw);
    ex.printStackTrace(pw);
    return sw.toString();
}

And then call it like so:

LOGGER.info(String.format("Exception occurred: %s", stackTraceToString(ex)));

I would be inclined to use a class in your css that alters the border style or border width when the button is depressed, so it gives the appearance of a toggle button.

Depending on your environment, you could use Rhino to do this, see Rhino website. This gives you access to all of the Java libraries from within JavaScript.

To calculate distance on Google Maps, you can use Directions API. That will be one of the easiest way to do it. To get data from Google Server, you can use Retrofit or Volley. Both has their own advantage. Take a look at following code where I have used retrofit to implement it:

private void build_retrofit_and_get_response(String type) {

    String url = "https://maps.googleapis.com/maps/";

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(url)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    RetrofitMaps service = retrofit.create(RetrofitMaps.class);

    Call<Example> call = service.getDistanceDuration("metric", origin.latitude + "," + origin.longitude,dest.latitude + "," + dest.longitude, type);

    call.enqueue(new Callback<Example>() {
        @Override
        public void onResponse(Response<Example> response, Retrofit retrofit) {

            try {
                //Remove previous line from map
                if (line != null) {
                    line.remove();
                }
                // This loop will go through all the results and add marker on each location.

Above is the code of function build_retrofit_and_get_response for calculating distance. Below is corresponding Retrofit Interface:

package com.androidtutorialpoint.googlemapsdistancecalculator;


import com.androidtutorialpoint.googlemapsdistancecalculator.POJO.Example;

import retrofit.Call;
import retrofit.http.GET;
import retrofit.http.Query;

public interface RetrofitMaps {


/*
 * Retrofit get annotation with our URL
 * And our method that will return us details of student.
 */
@GET("api/directions/json?key=AIzaSyC22GfkHu9FdgT9SwdCWMwKX1a4aohGifM")
Call<Example> getDistanceDuration(@Query("units") String units, @Query("origin") String origin, @Query("destination") String destination, @Query("mode") String mode);

}

I hope this explains your query. All the best :)

Here is an example using a 3rd party wrapper library for Vue called vue-moment.

In addition to binding Moment instance into Vue's root scope, this library includes moment and duration filters.

This example includes localization and is using ES6 module imports, an official standard, instead of NodeJS's CommonJS module system requires.

import Vue from 'vue';

import moment from 'moment';
import VueMoment from 'vue-moment';

// Load Locales ('en' comes loaded by default)
require('moment/locale/es');

// Choose Locale
moment.locale('es');

Vue.use(VueMoment, { moment });

Now you can use the Moment instance directly in your Vue templates without any additional markup:

<small>Copyright {{ $moment().year() }}</small>

Or the filters:

<span>{{ 3600000 | duration('humanize') }}</span>
<!-- "an hour" -->
<span>{{ [2, 'years'] | duration('add', 1, 'year') | duration('humanize') }}</span>
<!-- "3 years" -->

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

No guarantee, but I suspect IE uses the older Protected Storage API.

There are windows installers for MySQLdb avaialable for both 32 and 64 bit, supporting Python from 2.6 to 3.4. Check here.

You can use this template for every file type:

ValidationExpression="^.+\.(([pP][dD][fF])|([jJ][pP][gG])|([pP][nN][gG])))$"

for ex: you can add ([rR][aA][rR]) for Rar file type and etc ...

By the way, instead of generating the x and y coordinates yourself, you can also use the curve() function, which is intended to draw curves corresponding to a function (such as the density of a standard normal function).

see

help(curve)

and its examples.

And if you want to add som text to properly label the mean and standard deviations, you can use the text() function (see also plotmath, for annotations with mathematical symbols) .

see

help(text)
help(plotmath)

The answer with most vote partially worked for me. The browser url stayed the same but my routerLinkActive was not longer working after navigation.

My solution was to use lotation.go:

import { Component } from "@angular/core";
import { Location } from "@angular/common";
import { HttpParams } from "@angular/common/http";

export class whateverComponent {
  constructor(private readonly location: Location, private readonly router: Router) {}

  addQueryString() {
    const params = new HttpParams();
    params.append("param1", "value1");
    params.append("param2", "value2");
    this.location.go(this.router.url.split("?")[0], params.toString());
  }
}

I used HttpParams to build the query string since I was already using it to send information with httpClient. but you can just build it yourself.

and the this._router.url.split("?")[0], is to remove all previous query string from current url.

Please note this only works if the

<script>

tags are in the body and NOT in the head.

So

<head>
...
<script type="text/javascript" src="first.js"></script>
<script type="text/javascript" src="second.js"></script>
</head>

=> unknown function fn1()

Fails and

<body>
...
<script type="text/javascript" src="first.js"></script>
<script type="text/javascript" src="second.js"></script>
</body>

works.

The loopj library can be used straight-forward for this purpose:

SyncHttpClient client = new SyncHttpClient();
RequestParams params = new RequestParams();
params.put("text", "some string");
params.put("image", new File(imagePath));

client.post("http://example.com", params, new TextHttpResponseHandler() {
  @Override
  public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
    // error handling
  }

  @Override
  public void onSuccess(int statusCode, Header[] headers, String responseString) {
    // success
  }
});

You need to start by understanding that the target of a symlink is a pathname. And it can be absolute or relative to the directory which contains the symlink

Assuming you have foo.conf in sites-available

Try

cd sites-enabled
sudo ln -s ../sites-available/foo.conf .
ls -l

Now you will have a symlink in sites-enabled called foo.conf which has a target ../sites-available/foo.conf

Just to be clear, the normal configuration for Apache is that the config files for potential sites live in sites-available and the symlinks for the enabled sites live in sites-enabled, pointing at targets in sites-available. That doesn't quite seem to be the case the way you describe your setup, but that is not your primary problem.

If you want a symlink to ALWAYS point at the same file, regardless of the where the symlink is located, then the target should be the full path.

ln -s /etc/apache2/sites-available/foo.conf mysimlink-whatever.conf

Here is (line 1 of) the output of my ls -l /etc/apache2/sites-enabled:

lrwxrwxrwx 1 root root  26 Jun 24 21:06 000-default -> ../sites-available/default

See how the target of the symlink is relative to the directory that contains the symlink (it starts with ".." meaning go up one directory).

Hardlinks are totally different because the target of a hardlink is not a directory entry but a filing system Inode.

The important difference is that when passing by const reference, no new object is created. In the function body, the parameter is effectively an alias for the object passed in.

Because the reference is a const reference the function body cannot directly change the value of that object. This has a similar property to passing by value where the function body also cannot change the value of the object that was passed in, in this case because the parameter is a copy.

There are crucial differences. If the parameter is a const reference, but the object passed it was not in fact const then the value of the object may be changed during the function call itself.

E.g.

int a;

void DoWork(const int &n)
{
    a = n * 2;  // If n was a reference to a, n will have been doubled 

    f();  // Might change the value of whatever n refers to 
}

int main()
{
    DoWork(a);
}

Also if the object passed in was not actually const then the function could (even if it is ill advised) change its value with a cast.

e.g.

void DoWork(const int &n)
{
    const_cast<int&>(n) = 22;
}

This would cause undefined behaviour if the object passed in was actually const.

When the parameter is passed by const reference, extra costs include dereferencing, worse object locality, fewer opportunities for compile optimizing.

When the parameter is passed by value and extra cost is the need to create a parameter copy. Typically this is only of concern when the object type is large.

data-target is used by bootstrap to make your life easier. You (mostly) do not need to write a single line of Javascript to use their pre-made JavaScript components.

The data-target attribute should contain a CSS selector that points to the HTML Element that will be changed.

Modal Example Code from BS3:

<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  [...]
</div>

In this example, the button has data-target="#myModal", if you click on it, <div id="myModal">...</div> will be modified (in this case faded in). This happens because #myModal in CSS selectors points to elements that have an id attribute with the myModal value.

Further information about the HTML5 "data-" attribute: https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes

Here is one solution with jQuery for browsers that don't support the placeholder attribute.

$('[placeholder]').focus(function() {
  var input = $(this);

  if (input.val() == input.attr('placeholder')) {
    input.val('');
    input.removeClass('placeholder');
  }
}).blur(function() {
  var input = $(this);

  if (input.val() == '' || input.val() == input.attr('placeholder')) {
    input.addClass('placeholder');
    input.val(input.attr('placeholder'));
  }
}).blur();

Just trying to compile with ant, Have same error when using org.eclipse.jdt.core-3.5.2.v_981_R35x.jar, Everything is well after upgrade to org.eclipse.jdt.core_3.10.2.v20150120-1634.jar

Why not serialize the whole list at once?

FileOutputStream fout = new FileOutputStream("G:\\address.ser");
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(MyClassList);

Assuming, of course, that MyClassList is an ArrayList or LinkedList, or another Serializable collection.

In the case of reading it back, in your code you ready only one item, there is no loop to gather all the item written.

By default, NPM simply installs a package under node_modules. When you're trying to install dependencies for your app/module, you would need to first install them, and then add them to the dependencies section of your package.json.

--save-dev adds the third-party package to the package's development dependencies. It won't be installed when someone runs npm install directly to install your package. It's typically only installed if someone clones your source repository first and then runs npm install in it.

--save adds the third-party package to the package's dependencies. It will be installed together with the package whenever someone runs npm install package.

Dev dependencies are those dependencies that are only needed for developing the package. That can include test runners, compilers, packagers, etc. Both types of dependencies are stored in the package's package.json file. --save adds to dependencies, --save-dev adds to devDependencies

npm install documentation can be referred here.

--

Please note that --save is now the default option, since NPM 5. Therefore, it is not explicitly needed anymore. It is possible to run npm install without the --save to achieve the same result.

Try moving <uses-permission> outside the <application> tag.

ADDITIONAL NOTE (As this is very old question and has no accepted answer yet)

I am on xampp-win32-7.2.3-0-VC15-installer on Windows10-64bit.

here is the notes I see in my php.ini file.

Note : The syntax used in previous PHP versions ('extension=.so' and ; 'extension='php_.dll') is supported for legacy reasons and may be ; deprecated in a future PHP major version. So, when it is possible, please ; move to the new ('extension=) syntax.

So you will only find the extension name as intl instead of php_intl.dll and then uncommenting that line should work (It worked for me atleast).

extension=intl

Your regular expression should be \btrue\b to get around the 'miscontrue' issue Casper brings up. The full solution would look like this:

string searchText = "7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false";
string regexPattern = @"\btrue\b";
int numberOfTrues = Regex.Matches(searchText, regexPattern).Count;

Make sure the System.Text.RegularExpressions namespace is included at the top of the file.

What are they?

Nothing special. Just as same as common Java Class Instance.

But those class are Synthetic proxy classes created by java.lang.reflect.Proxy#newProxyInstance

What is there relationship to the JVM? Are they JVM implementation specific?

Introduced in 1.3

http://docs.oracle.com/javase/1.3/docs/relnotes/features.html#reflection

It is a part of Java. so each JVM should support it.

How are they created (Openjdk7 source)?

In short : they are created using JVM ASM tech ( defining javabyte code at runtime )

something using same tech:

• asm( http://asm.ow2.org/ )
• cglib( http://cglib.sourceforge.net/ )

What happens after calling java.lang.reflect.Proxy#newProxyInstance

1. reading the source you can see newProxyInstance call getProxyClass0 to obtain a `Class

   `

2. after lots of cache or sth it calls the magic ProxyGenerator.generateProxyClass which return a byte[]
3. call ClassLoader define class to load the generated $Proxy Class (the classname you have seen)
4. just instance it and ready for use

What happens in magic sun.misc.ProxyGenerator

1. draw a class(bytecode) combining all methods in the interfaces into one

2. each method is build with same bytecode like

   1. get calling Method meth info (stored while generating)
   2. pass info into invocation handler's invoke()
   3. get return value from invocation handler's invoke()
   4. just return it

3. the class(bytecode) represent in form of byte[]

How to draw a class

Thinking your java codes are compiled into bytecodes, just do this at runtime

Arrays like this are part of C99, but not part of standard C++. as others have said, a vector is always a much better solution, which is probably why variable sized arrays are not in the C++ standatrd (or in the proposed C++0x standard).

BTW, for questions on "why" the C++ standard is the way it is, the moderated Usenet newsgroup comp.std.c++ is the place to go to.

In my case i wrote comment in place of Component by mistake

I just wrote this.

import React, { Component } from 'react';

  class Something extends Component{
      render() {
          return();
     }
  }

Instead of this.

import React, { Component } from 'react';

  class Something extends comment{
      render() {
          return();
     }
  }

it's not a big deal but for a beginner like me it's really confusing. I hope this will be helpfull.

You can keep it disabled as desired, and then remove the disabled attribute before the form is submitted.

$('#myForm').submit(function() {
    $('select').removeAttr('disabled');
});

Note that if you rely on this method, you'll want to disable it programmatically as well, because if JS is disabled or not supported, you'll be stuck with the disabled select.

$(document).ready(function() {
    $('select').attr('disabled', 'disabled');
});

Directly calling a URL to get an image may concern with major security issues. You need to ensure that you have sufficient rights to access that resource. However You can use ByteOutputStream to read image file. This is an example (Its just an example, you need to do necessary changes as per your requirement.)

ByteArrayOutputStream bis = new ByteArrayOutputStream();
InputStream is = null;
try {
  is = url.openStream ();
  byte[] bytebuff = new byte[4096]; 
  int n;

  while ( (n = is.read(bytebuff)) > 0 ) {
    bis.write(bytebuff, 0, n);
  }
}

It is called a type parameter constraint. Effectively it constraints what type T can be.

The type argument must be a reference type; this applies also to any class, interface, delegate, or array type.

Constraints on Type Parameters (C# Programming Guide)

From http://www.coderanch.com/t/236675/java-programmer-SCJP/certification/xff

The hex literal 0xFF is an equal int(255). Java represents int as 32 bits. It look like this in binary:

00000000 00000000 00000000 11111111

When you do a bit wise AND with this value(255) on any number, it is going to mask(make ZEROs) all but the lowest 8 bits of the number (will be as-is).

... 01100100 00000101 & ...00000000 11111111 = 00000000 00000101

& is something like % but not really.

And why 0xff? this in ((power of 2) - 1). All ((power of 2) - 1) (e.g 7, 255...) will behave something like % operator.

Then
In binary, 0 is, all zeros, and 255 looks like this:

00000000 00000000 00000000 11111111

And -1 looks like this

11111111 11111111 11111111 11111111

When you do a bitwise AND of 0xFF and any value from 0 to 255, the result is the exact same as the value. And if any value higher than 255 still the result will be within 0-255.

However, if you do:

-1 & 0xFF

you get

00000000 00000000 00000000 11111111, which does NOT equal the original value of -1 (11111111 is 255 in decimal).

Few more bit manipulation: (Not related to the question)

X >> 1 = X/2
X << 1 = 2X

Check any particular bit is set(1) or not (0) then

 int thirdBitTobeChecked =   1 << 2   (...0000100)
 int onWhichThisHasTobeTested = 5     (.......101)

 int isBitSet = onWhichThisHasTobeTested  & thirdBitTobeChecked;
 if(isBitSet > 0) {
  //Third Bit is set to 1 
 } 

Set(1) a particular bit

 int thirdBitTobeSet =   1 << 2    (...0000100)
 int onWhichThisHasTobeSet = 2     (.......010)
 onWhichThisHasTobeSet |= thirdBitTobeSet;

ReSet(0) a particular bit

int thirdBitTobeReSet =   ~(1 << 2)  ; //(...1111011)
int onWhichThisHasTobeReSet = 6      ;//(.....000110)
onWhichThisHasTobeReSet &= thirdBitTobeReSet;

XOR

Just note that if you perform XOR operation twice, will results the same value.

byte toBeEncrypted = 0010 0110
byte salt          = 0100 1011

byte encryptedVal  =  toBeEncrypted ^ salt == 0110 1101
byte decryptedVal  =  encryptedVal  ^ salt == 0010 0110 == toBeEncrypted :)

One more logic with XOR is

if     A (XOR) B == C (salt)
then   C (XOR) B == A
       C (XOR) A == B

The above is useful to swap two variables without temp like below

a = a ^ b; b = a ^ b; a = a ^ b;

OR

a ^= b ^= a ^= b;

I had the same problem with one of my apps, which is how I ended up finding this. In my case, I uploaded two of my apps at the same time, using Xcode 7.1. One of the apps passed through processing within an hour. The other one was still in processing almost 24 hours later. To get past this issue, I created a new archive with an incremented build number, and uploaded it using the application loader. I did not turn off bitcode. The version that I uploaded using the application loader took less than 20 minutes to get through processing, and I've been able to submit my app for review. The version I submitted prior to this is still stuck in processing.

At least in the case of my app, using application loader appears to have solved the issue.

the user pressing enter or spaces is the same.

int count = 5;
int list[count]; // array of known length
cout << "enter the sequence of " << count << " numbers space separated: ";
// user inputs values space separated in one line.  Inputs more than the count are discarded.
for (int i=0; i<count; i++) {
    cin >> list[i];
}

jQuery is about 40 times SLOWER, please do not use jQuery for that simple task.

function htmlToPlaintext(text) {
  return text ? String(text).replace(/<[^>]+>/gm, '') : '';
}

usage :

var plain_text = htmlToPlaintext( your_html );

With angular.js :

angular.module('myApp.filters', []).
  filter('htmlToPlaintext', function() {
    return function(text) {
      return  text ? String(text).replace(/<[^>]+>/gm, '') : '';
    };
  }
);

use :

<div>{{myText | htmlToPlaintext}}</div>  

Example.

var request = require('request');

var url = "http://localhost:3000";

var requestData = {
    ...
} 

var data = {
    url: url,
    json: true,
    body: JSON.stringify(requestData)
}

request.post(data, function(error, httpResponse, body){
    console.log(body);
});

As inserting json: true option, sets body to JSON representation of value and adds "Content-type": "application/json" header. Additionally, parses the response body as JSON. LINK

GNU grep can inverse the search with the option -v. This makes grep reporting the lines, which do not match. By this you can remove the files in dir2 from the list of files in dir1.

grep -v -F -x -f <(find dir2 -type f -printf '%P\n') <(find dir1 -type f -printf '%P\n')

The options -F -x tell grep to perform a string search on the whole line.

Hey guys here is a simple test program that shows how to allocate and pass an array using new or malloc. Just cut, paste and run it. Have fun!

struct Coordinate
{
    int x,y;
};

void resize( int **p, int size )
{
   free( *p );
   *p = (int*) malloc( size * sizeof(int) );
}

void resizeCoord( struct Coordinate **p, int size )
{
   free( *p );
   *p = (Coordinate*) malloc( size * sizeof(Coordinate) );
}

void resizeCoordWithNew( struct Coordinate **p, int size )
{
   delete [] *p;
   *p = (struct Coordinate*) new struct Coordinate[size];
}

void SomeMethod(Coordinate Coordinates[])
{
    Coordinates[0].x++;
    Coordinates[0].y = 6;
}

void SomeOtherMethod(Coordinate Coordinates[], int size)
{
    for (int i=0; i<size; i++)
    {
        Coordinates[i].x = i;
        Coordinates[i].y = i*2;
    }
}

int main()
{
    //static array
    Coordinate tenCoordinates[10];
    tenCoordinates[0].x=0;
    SomeMethod(tenCoordinates);
    SomeMethod(&(tenCoordinates[0]));
    if(tenCoordinates[0].x - 2  == 0)
    {
        printf("test1 coord change successful\n");
    }
    else
    {
        printf("test1 coord change unsuccessful\n");
    }


   //dynamic int
   int *p = (int*) malloc( 10 * sizeof(int) );
   resize( &p, 20 );

   //dynamic struct with malloc
   int myresize = 20;
   int initSize = 10;
   struct Coordinate *pcoord = (struct Coordinate*) malloc (initSize * sizeof(struct Coordinate));
   resizeCoord(&pcoord, myresize); 
   SomeOtherMethod(pcoord, myresize);
   bool pass = true;
   for (int i=0; i<myresize; i++)
   {
       if (! ((pcoord[i].x == i) && (pcoord[i].y == i*2)))
       {        
           printf("Error dynamic Coord struct [%d] failed with (%d,%d)\n",i,pcoord[i].x,pcoord[i].y);
           pass = false;
       }
   }
   if (pass)
   {
       printf("test2 coords for dynamic struct allocated with malloc worked correctly\n");
   }


   //dynamic struct with new
   myresize = 20;
   initSize = 10;
   struct Coordinate *pcoord2 = (struct Coordinate*) new struct Coordinate[initSize];
   resizeCoordWithNew(&pcoord2, myresize); 
   SomeOtherMethod(pcoord2, myresize);
   pass = true;
   for (int i=0; i<myresize; i++)
   {
       if (! ((pcoord2[i].x == i) && (pcoord2[i].y == i*2)))
       {        
           printf("Error dynamic Coord struct [%d] failed with (%d,%d)\n",i,pcoord2[i].x,pcoord2[i].y);
           pass = false;
       }
   }
   if (pass)
   {
       printf("test3 coords for dynamic struct with new worked correctly\n");
   }

• hstore is more of a "wide column" storage type, it is a flat (non-nested) dictionary of key-value pairs, always stored in a reasonably efficient binary format (a hash table, hence the name).
• json stores JSON documents as text, performing validation when the documents are stored, and parsing them on output if needed (i.e. accessing individual fields); it should support the entire JSON spec. Since the entire JSON text is stored, its formatting is preserved.
• jsonb takes shortcuts for performance reasons: JSON data is parsed on input and stored in binary format, key orderings in dictionaries are not maintained, and neither are duplicate keys. Accessing individual elements in the JSONB field is fast as it doesn't require parsing the JSON text all the time. On output, JSON data is reconstructed and initial formatting is lost.

IMO, there is no significant reason for not using jsonb once it is available, if you are working with machine-readable data.

In case of Mac OSX,

Go to Targets -> Build Phases click + to Copy new files build phases Select product directory and drop the file there.

Clean and run the project.

getJSON() will also parse the JSON for you after fetching, so from then on, you are working with a simple Javascript array ([] marks an array in JSON). The documentation also has examples on how to handle the fetched data.

You can get all the values in an array using a for loop:

$.getJSON("url_with_json_here", function(data){
    for (var i = 0, len = data.length; i < len; i++) {
        console.log(data[i]);
    }
});

Check your console to see the output (Chrome, Firefox/Firebug, IE).

jQuery also provides $.each() for iterations, so you could also do this:

$.getJSON("url_with_json_here", function(data){
    $.each(data, function (index, value) {
        console.log(value);
    });
});

$myVar = $someVar ?? 42;

Is equivalent to :

$myVar = isset($someVar) ? $someVar : 42;

For constants, the behaviour is the same when using a constant that already exists :

define("FOO", "bar");
define("BAR", null);

$MyVar = FOO ?? "42";
$MyVar2 = BAR ?? "42";

echo $MyVar . PHP_EOL;  // bar
echo $MyVar2 . PHP_EOL; // 42

However, for constants that don't exist, this is different :

$MyVar3 = IDONTEXIST ?? "42"; // Raises a warning
echo $MyVar3 . PHP_EOL;       // IDONTEXIST

Warning: Use of undefined constant IDONTEXIST - assumed 'IDONTEXIST' (this will throw an Error in a future version of PHP)

Php will convert the non-existing constant to a string.

You can use constant("ConstantName") that returns the value of the constant or null if the constant doesn't exist, but it will still raise a warning. You can prepended the function with the error control operator @ to ignore the warning message :

$myVar = @constant("IDONTEXIST") ?? "42"; // No warning displayed anymore
echo $myVar . PHP_EOL; // 42

You might have forgotten to auto increment the id field.

This problem can also occur when you have conflicting tags. If your local version and remote version use same tag name for different commits, you can end up here.

You can solve it my deleting the local tag:

$ git tag --delete foo_tag

try like below it will work...

<html>
<head>
<script>
function displayResult(element)
{
document.getElementById(element).value = 'hi';
}
</script>
</head>
<body>

<textarea id="myTextarea" cols="20">
BYE
</textarea>
<br>

<button type="button" onclick="displayResult('myTextarea')">Change</button>

</body>
</html>

Also be advised, that while Java is in general very beginner friendly, getting into JavaEE, Servlets, Facelets, Eclipse integration, JSP and getting everything in Tomcat up and running is not. Certainly not the easiest way to build a website and probably way overkill for most things.

On top of that you may need to host your website yourself, because most webspace providers don't provide Servlet Containers. If you just want to check it out for fun, I would try Ruby or Python, which are much more cooler things to fiddle around with. But anyway, to provide at least something relevant to the question, here's a nice Servlet tutorial: link

'a' in x

and a quick search reveals some nice information about it: http://docs.python.org/3/tutorial/datastructures.html#dictionaries

The parenthesis are superfluous in your example. The pointer doesn't care whether there's an array involved - it only knows that its pointing to an int

  int g[] = {9,8};
  int (*j) = g;

could also be rewritten as

  int g[] = {9,8};
  int *j = g;

which could also be rewritten as

  int g[] = {9,8};
  int *j = &g[0];

a pointer-to-an-array would look like

  int g[] = {9,8};
  int (*j)[2] = &g;

  //Dereference 'j' and access array element zero
  int n = (*j)[0];

There's a good read on pointer declarations (and how to grok them) at this link here: http://www.codeproject.com/Articles/7042/How-to-interpret-complex-C-C-declarations

Old question I know, but for the curious:

Believe it or not, this issue was solved ~2 decades ago with HTTP BASIC, which passes the value as base64 encoded username:password. (See http://en.wikipedia.org/wiki/Basic_access_authentication#Client_side)

You could do the same, so that the example above would become:

Authorization: FIRE-TOKEN MFBONUoxN0hCR1pIVDdKSjNYODI6ZnJKSVVOOERZcEtEdE9MQ3dvLy95bGxxRHpnPQ==

I just needed to do this, and I found that you can easily add files in subdirectories. You only need to be on the "top directory" of the repo, and then run something like:

$ git add ./subdir/file_in_subdir.txt

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before and an :after pseudo-element — it just cannot have more than one of each kind.)

As a result, when you have multiple :before rules matching the same element, they will all cascade and apply to a single :before pseudo-element, as with a normal element. In your example, the end result looks like this:

.circle.now:before {
    content: "Now";
    font-size: 19px;
    color: black;
}

As you can see, only the content declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.

This behavior is described in the Selectors section of CSS2.1:

Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.

This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.

If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before or .now.circle:before — whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content property that you will need to define yourself.

If you still need a concrete example, see my answer to this similar question.

The legacy css3-content specification contains a section on inserting multiple ::before and ::after pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.

Pushwatch is a free to use online GCM and APNS push notification tester developed by myself in Django/Python as I have found myself in a similar situation while working on multiple projects. It can send both GCM and APNS notifications and also support JSON messages for extra arguments. Following are the links to the testers.

Please let me know if you have any questions or face issues using it.

EDITED TO ADD: The following code is outdated and won't work in PHP 7. See the note towards the bottom of the answer for more details.

Assuming a table structure of an integer ID and a blob DATA column, and assuming MySQL functions are being used to interface with the database, you could probably do something like this:

$result = mysql_query 'INSERT INTO table (
    data
) VALUES (
    \'' . mysql_real_escape_string (file_get_contents ('/path/to/the/file/to/store.pdf')) . '\'
);';

A word of warning though, storing blobs in databases is generally not considered to be the best idea as it can cause table bloat and has a number of other problems associated with it. A better approach would be to move the file somewhere in the filesystem where it can be retrieved, and store the path to the file in the database instead of the file itself.

Also, using mysql_* function calls is discouraged as those methods are effectively deprecated and aren't really built with versions of MySQL newer than 4.x in mind. You should switch to mysqli or PDO instead.

UPDATE: mysql_* functions are deprecated in PHP 5.x and are REMOVED COMPLETELY IN PHP 7! You now have no choice but to switch to a more modern Database Abstraction (MySQLI, PDO). I've decided to leave the original answer above intact for historical reasons but don't actually use it

Here's how to do it with mysqli in procedural mode:

$result = mysqli_query ($db, 'INSERT INTO table (
    data
) VALUES (
    \'' . mysqli_real_escape_string (file_get_contents ('/path/to/the/file/to/store.pdf'), $db) . '\'
);');

The ideal way of doing it is with MySQLI/PDO prepared statements.

You wouldn't really want to do this given the existing Instr/InstrRev functions but there are times when it is handy to use EVALUATE to return the result of Excel worksheet functions within VBA

Option Explicit

Public Sub test()

    Debug.Print ContainsSubString("bc", "abc,d")

End Sub
Public Function ContainsSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'substring = string to test for; testString = string to search
    ContainsSubString = Evaluate("=ISNUMBER(FIND(" & Chr$(34) & substring & Chr$(34) & ", " & Chr$(34) & testString & Chr$(34) & "))")

End Function

This is the behavior of ln if the second arg is a directory. It places a link to the first arg inside it. If you want /etc/nginx to be the symlink, you should remove that directory first and run that same command.

This works

iframe{
    border-width: 0px;
}

Use conditional comments in HTML, like this:

<!--[if IE 8]>
<style>...</style>
<![endif]-->

See here: http://www.quirksmode.org/css/condcom.html

You can test for IE versions reliably and also be sure other browsers won't be confused.

FWIW, you can provide an error message like so:

USERNAME=${1:?"Specify a username"}

This displays a message like this and exits with code 1:

./myscript.sh
./myscript.sh: line 2: 1: Specify a username

A more complete example of everything:

#!/bin/bash
ACTION=${1:?"Specify 'action' as argv[1]"}
DIRNAME=${2:-$PWD}
OUTPUT_DIR=${3:-${HOMEDIR:-"/tmp"}}

echo "$ACTION"
echo "$DIRNAME"
echo "$OUTPUT_DIR"

Output:

$ ./script.sh foo
foo
/path/to/pwd
/tmp

$ export HOMEDIR=/home/myuser
$ ./script.sh foo
foo
/path/to/pwd
/home/myuser

• $ACTION takes the value of the first argument, and exits if empty
• $DIRNAME is the 2nd argument, and defaults to the current directory
• $OUTPUT_DIR is the 3rd argument, or $HOMEDIR (if defined), else, /tmp. This works on OS X, but I'm not positive that it's portable.

alter tablespace TABLE_SPACE_NAME add datafile 'D:\oracle\Oradata\TEMP04.dbf'

I use this function (SQL Server 2005 and above).

Simply switch to the Design View, and locate the concerned widget. Grab the one of the dots on the boundary of the widget and join it to an appropriate edge of the screen (or to a dot on some other widget).

For instance, if the widget is a toolbar, just grab the top-most dot and join it to the top-most edge of the phone screen as shown in the image.

My solution was to add:

ctlUpdatePanel.Update();

after binding control after postback. it was in updatepanel with UpdateMode="Conditional" attribute.

Short answer

git rev-list --max-parents=0 HEAD

_{(from tiho's comment. As Chris Johnsen notices, --max-parents was introduced after this answer was posted.)}

Explanation

Technically, there may be more than one root commit. This happens when multiple previously independent histories are merged together. It is common when a project is integrated via a subtree merge.

The git.git repository has six root commits in its history graph (one each for Linus’s initial commit, gitk, some initially separate tools, git-gui, gitweb, and git-p4). In this case, we know that e83c516 is the one we are probably interested in. It is both the earliest commit and a root commit.

It is not so simple in the general case.

Imagine that libfoo has been in development for a while and keeps its history in a Git repository (libfoo.git). Independently, the “bar” project has also been under development (in bar.git), but not for as long libfoo (the commit with the earliest date in libfoo.git has a date that precedes the commit with the earliest date in bar.git). At some point the developers of “bar” decide to incorporate libfoo into their project by using a subtree merge. Prior to this merge it might have been trivial to determine the “first” commit in bar.git (there was probably only one root commit). After the merge, however, there are multiple root commits and the earliest root commit actually comes from the history of libfoo, not “bar”.

You can find all the root commits of the history DAG like this:

git rev-list --max-parents=0 HEAD

For the record, if --max-parents weren't available, this does also work:

git rev-list --parents HEAD | egrep "^[a-f0-9]{40}$"

If you have useful tags in place, then git name-rev might give you a quick overview of the history:

git rev-list --parents HEAD | egrep "^[a-f0-9]{40}$" | git name-rev --stdin

Bonus

Use this often? Hard to remember? Add a git alias for quick access

git config --global alias.first "rev-list --max-parents=0 HEAD"

Now you can simply do

git first

Julien Danjou wrote a good article explaining why you should never deal with timezones. An excerpt:

Indeed, Python datetime API always returns unaware datetime objects, which is very unfortunate. Indeed, as soon as you get one of this object, there is no way to know what the timezone is, therefore these objects are pretty "useless" on their own.

Alas, even though you may use utcnow(), you still won't see the timezone info, as you discovered.

Recommendations:

• Always use aware datetime objects, i.e. with timezone information. That makes sure you can compare them directly (aware and unaware datetime objects are not comparable) and will return them correctly to users. Leverage pytz to have timezone objects.

• Use ISO 8601 as the input and output string format. Use datetime.datetime.isoformat() to return timestamps as string formatted using that format, which includes the timezone information.

• If you need to parse strings containing ISO 8601 formatted timestamps, you can rely on iso8601, which returns timestamps with correct timezone information. This makes timestamps directly comparable.

That because the element is the "Select" and not "Option" in which you have the custom tag.

Try this: $("#location option:selected").attr("myTag").

Hope this helps.

put your jquery function inside ready function for call click event:

$(document).ready(function() {

  $("#ancherComplaint").click(function () {
     alert($(this).attr("id"));
  });

});

If you want to keep the general styling (rounded corners etc.) and just change the background color then I use the backgroundTint property

android:backgroundTint="@android:color/holo_green_light"

How can I make as "perfect" a subclass of dict as possible?

The end goal is to have a simple dict in which the keys are lowercase.

• If I override __getitem__/__setitem__, then get/set don't work. How do I make them work? Surely I don't need to implement them individually?

• Am I preventing pickling from working, and do I need to implement __setstate__ etc?

• Do I need repr, update and __init__?

• Should I just use mutablemapping (it seems one shouldn't use UserDict or DictMixin)? If so, how? The docs aren't exactly enlightening.

The accepted answer would be my first approach, but since it has some issues, and since no one has addressed the alternative, actually subclassing a dict, I'm going to do that here.

What's wrong with the accepted answer?

This seems like a rather simple request to me:

How can I make as "perfect" a subclass of dict as possible? The end goal is to have a simple dict in which the keys are lowercase.

The accepted answer doesn't actually subclass dict, and a test for this fails:

>>> isinstance(MyTransformedDict([('Test', 'test')]), dict)
False

Ideally, any type-checking code would be testing for the interface we expect, or an abstract base class, but if our data objects are being passed into functions that are testing for dict - and we can't "fix" those functions, this code will fail.

Other quibbles one might make:

• The accepted answer is also missing the classmethod: fromkeys.

• The accepted answer also has a redundant __dict__ - therefore taking up more space in memory:

  >>> s.foo = 'bar'
  >>> s.__dict__
  {'foo': 'bar', 'store': {'test': 'test'}}
  

Actually subclassing dict

We can reuse the dict methods through inheritance. All we need to do is create an interface layer that ensures keys are passed into the dict in lowercase form if they are strings.

If I override __getitem__/__setitem__, then get/set don't work. How do I make them work? Surely I don't need to implement them individually?

Well, implementing them each individually is the downside to this approach and the upside to using MutableMapping (see the accepted answer), but it's really not that much more work.

First, let's factor out the difference between Python 2 and 3, create a singleton (_RaiseKeyError) to make sure we know if we actually get an argument to dict.pop, and create a function to ensure our string keys are lowercase:

from itertools import chain
try:              # Python 2
    str_base = basestring
    items = 'iteritems'
except NameError: # Python 3
    str_base = str, bytes, bytearray
    items = 'items'

_RaiseKeyError = object() # singleton for no-default behavior

def ensure_lower(maybe_str):
    """dict keys can be any hashable object - only call lower if str"""
    return maybe_str.lower() if isinstance(maybe_str, str_base) else maybe_str

Now we implement - I'm using super with the full arguments so that this code works for Python 2 and 3:

class LowerDict(dict):  # dicts take a mapping or iterable as their optional first argument
    __slots__ = () # no __dict__ - that would be redundant
    @staticmethod # because this doesn't make sense as a global function.
    def _process_args(mapping=(), **kwargs):
        if hasattr(mapping, items):
            mapping = getattr(mapping, items)()
        return ((ensure_lower(k), v) for k, v in chain(mapping, getattr(kwargs, items)()))
    def __init__(self, mapping=(), **kwargs):
        super(LowerDict, self).__init__(self._process_args(mapping, **kwargs))
    def __getitem__(self, k):
        return super(LowerDict, self).__getitem__(ensure_lower(k))
    def __setitem__(self, k, v):
        return super(LowerDict, self).__setitem__(ensure_lower(k), v)
    def __delitem__(self, k):
        return super(LowerDict, self).__delitem__(ensure_lower(k))
    def get(self, k, default=None):
        return super(LowerDict, self).get(ensure_lower(k), default)
    def setdefault(self, k, default=None):
        return super(LowerDict, self).setdefault(ensure_lower(k), default)
    def pop(self, k, v=_RaiseKeyError):
        if v is _RaiseKeyError:
            return super(LowerDict, self).pop(ensure_lower(k))
        return super(LowerDict, self).pop(ensure_lower(k), v)
    def update(self, mapping=(), **kwargs):
        super(LowerDict, self).update(self._process_args(mapping, **kwargs))
    def __contains__(self, k):
        return super(LowerDict, self).__contains__(ensure_lower(k))
    def copy(self): # don't delegate w/ super - dict.copy() -> dict :(
        return type(self)(self)
    @classmethod
    def fromkeys(cls, keys, v=None):
        return super(LowerDict, cls).fromkeys((ensure_lower(k) for k in keys), v)
    def __repr__(self):
        return '{0}({1})'.format(type(self).__name__, super(LowerDict, self).__repr__())

We use an almost boiler-plate approach for any method or special method that references a key, but otherwise, by inheritance, we get methods: len, clear, items, keys, popitem, and values for free. While this required some careful thought to get right, it is trivial to see that this works.

(Note that haskey was deprecated in Python 2, removed in Python 3.)

Here's some usage:

>>> ld = LowerDict(dict(foo='bar'))
>>> ld['FOO']
'bar'
>>> ld['foo']
'bar'
>>> ld.pop('FoO')
'bar'
>>> ld.setdefault('Foo')
>>> ld
{'foo': None}
>>> ld.get('Bar')
>>> ld.setdefault('Bar')
>>> ld
{'bar': None, 'foo': None}
>>> ld.popitem()
('bar', None)

Am I preventing pickling from working, and do I need to implement __setstate__ etc?

pickling

And the dict subclass pickles just fine:

>>> import pickle
>>> pickle.dumps(ld)
b'\x80\x03c__main__\nLowerDict\nq\x00)\x81q\x01X\x03\x00\x00\x00fooq\x02Ns.'
>>> pickle.loads(pickle.dumps(ld))
{'foo': None}
>>> type(pickle.loads(pickle.dumps(ld)))
<class '__main__.LowerDict'>

__repr__

Do I need repr, update and __init__?

We defined update and __init__, but you have a beautiful __repr__ by default:

>>> ld # without __repr__ defined for the class, we get this
{'foo': None}

However, it's good to write a __repr__ to improve the debugability of your code. The ideal test is eval(repr(obj)) == obj. If it's easy to do for your code, I strongly recommend it:

>>> ld = LowerDict({})
>>> eval(repr(ld)) == ld
True
>>> ld = LowerDict(dict(a=1, b=2, c=3))
>>> eval(repr(ld)) == ld
True

You see, it's exactly what we need to recreate an equivalent object - this is something that might show up in our logs or in backtraces:

>>> ld
LowerDict({'a': 1, 'c': 3, 'b': 2})

Conclusion

Should I just use mutablemapping (it seems one shouldn't use UserDict or DictMixin)? If so, how? The docs aren't exactly enlightening.

Yeah, these are a few more lines of code, but they're intended to be comprehensive. My first inclination would be to use the accepted answer, and if there were issues with it, I'd then look at my answer - as it's a little more complicated, and there's no ABC to help me get my interface right.

Premature optimization is going for greater complexity in search of performance. MutableMapping is simpler - so it gets an immediate edge, all else being equal. Nevertheless, to lay out all the differences, let's compare and contrast.

I should add that there was a push to put a similar dictionary into the collections module, but it was rejected. You should probably just do this instead:

my_dict[transform(key)]

It should be far more easily debugable.

Compare and contrast

There are 6 interface functions implemented with the MutableMapping (which is missing fromkeys) and 11 with the dict subclass. I don't need to implement __iter__ or __len__, but instead I have to implement get, setdefault, pop, update, copy, __contains__, and fromkeys - but these are fairly trivial, since I can use inheritance for most of those implementations.

The MutableMapping implements some things in Python that dict implements in C - so I would expect a dict subclass to be more performant in some cases.

We get a free __eq__ in both approaches - both of which assume equality only if another dict is all lowercase - but again, I think the dict subclass will compare more quickly.

Summary:

• subclassing MutableMapping is simpler with fewer opportunities for bugs, but slower, takes more memory (see redundant dict), and fails isinstance(x, dict)
• subclassing dict is faster, uses less memory, and passes isinstance(x, dict), but it has greater complexity to implement.

Which is more perfect? That depends on your definition of perfect.

This was the only thing that worked for me, I added the following annotation to my Application class and exclude SecurityAutoConfiguration

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration;

@EnableAutoConfiguration(exclude = {
        SecurityAutoConfiguration.class
})

Object.entries(myObj).forEach(([key, value]) => {
    console.log(key + ' - ' + value) // key - value
})

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

That wasn't working for me, but this did the trick:

<key>NSAppTransportSecurity</key>  
     <dict>  
          <key>NSAllowsArbitraryLoads</key><true/>  
     </dict>  

The cleanest way to achieve this in PHP is to simply use DESCRIBE statement.

if ( mysql_query( "DESCRIBE `my_table`" ) ) {
    // my_table exists
}

I'm not sure why others are posting complicated queries for a such a straight forward problem.

Update

Using PDO

// assuming you have already setup $pdo
$sh = $pdo->prepare( "DESCRIBE `my_table`");
if ( $sh->execute() ) {
    // my_table exists
} else {
    // my_table does not exist    
}

Simple Steps, follow them and i guess it will solve your problem

Include these Css in your page,

.progress {
      position: relative;
      height: 2px;

      background-color: #2C67B1;
      top: 0;
      left: 0;
      bottom: 0;
      will-change: left, right;
      -webkit-animation: indeterminate 2.1s cubic-bezier(0.65, 0.815, 0.735, 0.395) infinite;
              animation: indeterminate 2.1s cubic-bezier(0.65, 0.815, 0.735, 0.395) infinite; }
    .progress .indeterminate:after {

      will-change: left, right;
      -webkit-animation: indeterminate-short 2.1s cubic-bezier(0.165, 0.84, 0.44, 1) infinite;
              animation: indeterminate-short 2.1s cubic-bezier(0.165, 0.84, 0.44, 1) infinite;
      -webkit-animation-delay: 1.15s;
              animation-delay: 1.15s; }

    @-webkit-keyframes indeterminate {
      0% {
        left: -35%;
        right: 100%; }
      60% {
        left: 100%;
        right: -90%; }
      100% {
        left: 100%;
        right: -90%; } }
    @keyframes indeterminate {
      0% {
        left: -35%;
        right: 100%; }
      60% {
        left: 100%;
        right: -90%; }
      100% {
        left: 100%;
        right: -90%; } }
    @-webkit-keyframes indeterminate-short {
      0% {
        left: -200%;
        right: 100%; }
      60% {
        left: 107%;
        right: -8%; }
      100% {
        left: 107%;
        right: -8%; } }
    @keyframes indeterminate-short {
      0% {
        left: -200%;
        right: 100%; }
      60% {
        left: 107%;
        right: -8%; }
      100% {
        left: 107%;
        right: -8%; } }

Then include the progress bar your body tag,

<div class="progress" id="PreLoaderBar">
        <div class="indeterminate"></div>
    </div>

then it will start as your page loads, and now what you have to do is just hide this when the page loads,or set the visibility to none, or hidden, using javascript,

document.onreadystatechange = function () {
            if (document.readyState === "complete") {
                console.log(document.readyState);
                document.getElementById("PreLoaderBar").style.display = "none";
            }
        }

Let me Know if you face any problems and also, you can add any type of progress bar you can easily find them, for this example i have used a indeterminate progress bar.

I would stick with normal approach to call the file directly, but if you really want to call a function, have a look at JSON-RPC (JSON Remote Procedure Call).

You basically send a JSON string in a specific format to the server, e.g.

{ "method": "echo", "params": ["Hello JSON-RPC"], "id": 1}

which includes the function to call and the parameters of that function.

Of course the server has to know how to handle such requests.
Here is jQuery plugin for JSON-RPC and e.g. the Zend JSON Server as server implementation in PHP.

This might be overkill for a small project or less functions. Easiest way would be karim's answer. On the other hand, JSON-RPC is a standard.

Choose the size of the array (in this example, I have chosen the size to be 20). And then, use the following:

import numpy as np   
np.random.randint(10, size=(1, 20))

You can expect to see an output of the following form (different random integers will be returned each time you run it; hence you can expect the integers in the output array to differ from the example given below).

array([[1, 6, 1, 2, 8, 6, 3, 3, 2, 5, 6, 5, 0, 9, 5, 6, 4, 5, 9, 3]])

Even if its not inline-block based, this solution might worth consideration (allows nearly same formatting control from upper levels).

ul {
  display: table;
}
ul li {
  display: table-cell;
}

• IE8+ & major browsers compatible
• Relative/fixed font-size independent
• HTML code formatting independent (no need to glue </li><li>)

It depends on what do you mean by python functions? if they were written in cpython you can not directly call them you will have to use JNI, but if they were written in Jython you can easily call them from java, as jython ultimately generates java byte code.

Now when I say written in cpython or jython it doesn't make much sense because python is python and most code will run on both implementations unless you are using specific libraries which relies on cpython or java.

see here how to use Python interpreter in Java.

Your approach is correct. (Depending on the circumstances, you might want to use configurations.all { exclude ... }.) If these excludes really exclude more than a single dependency (I haven't ever noticed that when using them), please file a bug at http://forums.gradle.org, ideally with a reproducible example.

My solution to this problem encountered using ASP.NET Core 2.0 and EF Core 2.0 was to perform the following in order:

1. Run update-database command in Package Management Console (PMC) to create the database (this results in the "Introducing FOREIGN KEY constraint ... may cause cycles or multiple cascade paths." error)

2. Run script-migration -Idempotent command in PMC to create a script that can be run regardless of the existing tables/constraints

3. Take the resulting script and find ON DELETE CASCADE and replace with ON DELETE NO ACTION

4. Execute the modified SQL against the database

Now, your migrations should be up-to-date and the cascading deletes should not occur.

Too bad I was not able to find any way to do this in Entity Framework Core 2.0.

Good luck!

This is fixable in the application code by setting the button's TransformationMethod null, e.g.

mButton.setTransformationMethod(null);

I didn't apply paging on my gridview and it extends to more than 600 records (with checkbox, buttons, etc.) and the value of 2001 didn't work. You may increase the value, say 10000 and test.

<appSettings>
<add key="aspnet:MaxHttpCollectionKeys" value="10000" />
</appSettings>

I didn't have luck with some of the above,

This was the only one that actually worked for me

ul:not(:first-of-type) {}

This worked for me when I was trying to have the first button displayed on the page not be effected by a margin-left option.

this was the option I tried first but it didn't work

ul:not(:first-child)

Here is an alternative. Create a generic exception that takes a status code and a message. Then create an exception handler. Use the exception handler to retrieve the information out of the exception and return to the caller of the service.

http://javaninja.net/2016/06/throwing-exceptions-messages-spring-mvc-controller/

public class ResourceException extends RuntimeException {

    private HttpStatus httpStatus = HttpStatus.INTERNAL_SERVER_ERROR;

    public HttpStatus getHttpStatus() {
        return httpStatus;
    }

    /**
     * Constructs a new runtime exception with the specified detail message.
     * The cause is not initialized, and may subsequently be initialized by a
     * call to {@link #initCause}.
     * @param message the detail message. The detail message is saved for later retrieval by the {@link #getMessage()}
     *                method.
     */
    public ResourceException(HttpStatus httpStatus, String message) {
        super(message);
        this.httpStatus = httpStatus;
    }
}

Then use an exception handler to retrieve the information and return it to the service caller.

@ControllerAdvice
public class ExceptionHandlerAdvice { 

    @ExceptionHandler(ResourceException.class)
    public ResponseEntity handleException(ResourceException e) {
        // log exception 
        return ResponseEntity.status(e.getHttpStatus()).body(e.getMessage());
    }         
} 

Then create an exception when you need to.

throw new ResourceException(HttpStatus.NOT_FOUND, "We were unable to find the specified resource.");

Another OSX-Mac option is to uncheck View->Allow Mouse Reporting (or press ?-R to toggle it.) This allows you to toggle between mouse interaction and mouse selecting, which might be useful when selecting and copy/pasting a few bits because you don't have to hold a modifier key to do it.

Note for Multiline with line numbers:

I usually have line numbers enabled so this will also copy the line numbers if you select multiple lines. If you want to copy multiple lines without the line numbers disable the numbers with :set nonu and then you can :set nu to re-enable them after you're done copying.

By far the easiest solution is to just use the Google Chart API http://code.google.com/apis/chart/

You can make bar graphs, pie charts, use 3D, and it's as easy as building a url with some parameters. See the simple example below.

In your androidmanifest.xml file:

   <activity android:name="MainActivity" android:configChanges="keyboardHidden|orientation">

or

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

You need to enclose your class in { and }. A few extra pointers: According to the Java coding conventions, you should

• Put your { on the same line as the method declaration:
• Name your classes using CamelCase (with initial capital letter)
• Name your methods using camelCase (with small initial letter)

Here's how I would write it:

public class ModMyMod extends BaseMod {

    public String version() {
         return "1.2_02";
    }

    public void addRecipes(CraftingManager recipes) {
       recipes.addRecipe(new ItemStack(Item.diamond), new Object[] {
          "#", Character.valueOf('#'), Block.dirt
       });
    }
}

I see readytocloud.com is hosted on Apache 2.2.

There is a much simpler and more efficient way to redirect the non-www site to the www site in Apache.

Add the following rewrite rules to the Apache configs (either inside the virtual host or outside. It doesn't matter):

RewriteCond %{HTTP_HOST} ^readytocloud.com [NC]
RewriteRule ^/$ http://www.readytocloud.com/ [R=301,L]

Or, the following rewrite rules if you want a 1-to-1 mapping of URLs from the non-www site to the www site:

RewriteCond %{HTTP_HOST} ^readytocloud.com [NC]
RewriteRule (.*) http://www.readytocloud.com$1 [R=301,L]

Note, the mod_rewrite module needs to be loaded for this to work. Luckily readytocloud.com is runing on a CentOS box, which by default loads mod_rewrite.

We have a client server running Apache 2.2 with just under 3,000 domains and nearly 4,000 redirects, however, the load on the server hover around 0.10 - 0.20.

It's called and and or in Python.

Try this:

a = 1
b = 2
int_div  = a // b

I know this is old, but I have to add this in here..

And while this is not a full answer, it is an 'IN ADDITION TO'

The address bar will not disappear if you're NOT using https.

ALSO

If you are using https and the address bar still won't hide, you might have some https errors in your webpage (such as certain images being served from a non-https location.)

Hope this helps..

Process.WaitForExit should be just what you're looking for I think.

If you want to search special file with wildcard, you can used following code:

find . -type f -name "*.conf"

Suppose, you want to search every .conf files from here:

. means search started from here (current place)
-type means type of search item that here is file (f).
-name means you want to search files with *.conf names.

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

in JQuery you can use: in class for Select Option:

$('.className').each(function(){
    className.push($("option:selected",this).val().substr(1));
});

in class for text Value:

$('.className').each(function(){
    className.push($(this).val().substr(1));
});

in ID for text Value:

$("#id").val().substr(1)

You've answered the question with this statement:

Cron calls this .sh every 2 minutes

Cron does not run in a terminal, so why would you expect one to be set?

The most common reason for getting this error message is because the script attempts to source the user's .profile which does not check that it's running in a terminal before doing something tty related. Workarounds include using a shebang line like:

#!/bin/bash -p

Which causes the sourcing of system-level profile scripts which (one hopes) does not attempt to do anything too silly and will have guards around code that depends on being run from a terminal.

If this is the entirety of the script, then the TERM error is coming from something other than the plain content of the script.

A "const function", denoted with the keyword const after a function declaration, makes it a compiler error for this class function to change a member variable of the class. However, reading of a class variables is okay inside of the function, but writing inside of this function will generate a compiler error.

Another way of thinking about such "const function" is by viewing a class function as a normal function taking an implicit this pointer. So a method int Foo::Bar(int random_arg) (without the const at the end) results in a function like int Foo_Bar(Foo* this, int random_arg), and a call such as Foo f; f.Bar(4) will internally correspond to something like Foo f; Foo_Bar(&f, 4). Now adding the const at the end (int Foo::Bar(int random_arg) const) can then be understood as a declaration with a const this pointer: int Foo_Bar(const Foo* this, int random_arg). Since the type of this in such case is const, no modifications of member variables are possible.

It is possible to loosen the "const function" restriction of not allowing the function to write to any variable of a class. To allow some of the variables to be writable even when the function is marked as a "const function", these class variables are marked with the keyword mutable. Thus, if a class variable is marked as mutable, and a "const function" writes to this variable then the code will compile cleanly and the variable is possible to change. (C++11)

As usual when dealing with the const keyword, changing the location of the const key word in a C++ statement has entirely different meanings. The above usage of const only applies when adding const to the end of the function declaration after the parenthesis.

const is a highly overused qualifier in C++: the syntax and ordering is often not straightforward in combination with pointers. Some readings about const correctness and the const keyword:

The C++ 'const' Declaration: Why & How

Another option for the same result with ConstraintSet animation:

1) Put all the animated views in one ConstraintLayout

2) Animate it from code like this (if you want some more effects its up to you..this is only example)

menuItem1 and menuItem2 is the first and second FABs in menu, descriptionItem1 and descriptionItem2 is the description to the left of menu, parentConstraintLayout is the root ConstraintLayout wich contains all the animated views, isMenuOpened is some function to change open/closed flag in the state

I put animation code in extension file but its not necessary.

fun FloatingActionButton.expandMenu(
    menuItem1: View,
    menuItem2: View,
    descriptionItem1: TextView,
    descriptionItem2: TextView,
    parentConstraintLayout: ConstraintLayout,
    isMenuOpened: (Boolean)-> Unit
) {
    val constraintSet = ConstraintSet()
    constraintSet.clone(parentConstraintLayout)

    constraintSet.setVisibility(descriptionItem1.id, View.VISIBLE)
    constraintSet.clear(menuItem1.id, ConstraintSet.TOP)
    constraintSet.connect(menuItem1.id, ConstraintSet.BOTTOM, this.id, ConstraintSet.TOP, 0)
    constraintSet.connect(menuItem1.id, ConstraintSet.START, this.id, ConstraintSet.START, 0)
    constraintSet.connect(menuItem1.id, ConstraintSet.END, this.id, ConstraintSet.END, 0)

    constraintSet.setVisibility(descriptionItem2.id, View.VISIBLE)
    constraintSet.clear(menuItem2.id, ConstraintSet.TOP)
    constraintSet.connect(menuItem2.id, ConstraintSet.BOTTOM, menuItem1.id, ConstraintSet.TOP, 0)
    constraintSet.connect(menuItem2.id, ConstraintSet.START, this.id, ConstraintSet.START, 0)
    constraintSet.connect(menuItem2.id, ConstraintSet.END, this.id, ConstraintSet.END, 0)

    val transition = AutoTransition()
    transition.duration = 150
    transition.interpolator = AccelerateInterpolator()

    transition.addListener(object: Transition.TransitionListener {
        override fun onTransitionEnd(p0: Transition) {
            isMenuOpened(true)
        }
        override fun onTransitionResume(p0: Transition) {}
        override fun onTransitionPause(p0: Transition) {}
        override fun onTransitionCancel(p0: Transition) {}
        override fun onTransitionStart(p0: Transition) {}
    })

    TransitionManager.beginDelayedTransition(parentConstraintLayout, transition)
    constraintSet.applyTo(parentConstraintLayout)
}

Note that %in% returns a logical vector of TRUE and FALSE. To negate it, you can use ! in front of the logical statement:

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
 !where_case_travelled_1 %in% 
   c('Outside Canada','Outside province/territory of residence but within Canada'))

Regarding your original approach with -c(...), - is a unary operator that "performs arithmetic on numeric or complex vectors (or objects which can be coerced to them)" (from help("-")). Since you are dealing with a character vector that cannot be coerced to numeric or complex, you cannot use -.

Use elevation instead of zIndex for android devices

elevatedElement: {
  zIndex: 3, // works on ios
  elevation: 3, // works on android
}

This worked fine for me!

For those trouble shooting, it is important to know that ng-include requires the url path to be from the app root directory and not from the same directory where the partial.html lives. (whereas partial.html is the view file that the inline ng-include markup tag can be found).

For example:

Correct: div ng-include src=" '/views/partials/tabSlides/add-more.html' ">

Incorrect: div ng-include src=" 'add-more.html' ">

A real-life example: a complicated database that needs to be shown on a website. Since the database was designed somewhere around 1986 (!), lots of data was packed in different ways to save on disk space.

As the development went on, the developers could no longer solve complicated data requests in SQL alone, for example because the sorting algorythms were unusual.

There are three sensible solutions:

1. quick and dirty: send the unsored data to PHP, sort it there. Obviously a very expensive solution, because this would be repeated every time the page is called
2. write a plugin to the database engine -- but the admin wasn't ready to allow foreign code to run on their server, or
3. you can process the data in a program (C, Perl, etc.), and output HTML. The program itself goes into /cgi-bin, and is called by the web server (e.g. Apache) directly, not through PHP.

CGI runs your script in Solution #3 and outputs the effect to the browser. You have the speed of the compiled program, the flexibility of a language better than SQL, and no need to write plugins to the SQL server. (Again, this is an example specific to SQL and C)

Another, perhaps simpler, solution is to add your override template directory to the DIRS entry of the TEMPLATES setting in settings.py. (I think this setting is new in Django 1.8. It may have been called TEMPLATE_DIRS in previous Django versions.)

Like so:

TEMPLATES = [
   {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        # allow overriding templates from other installed apps                                                                                                
        'DIRS': ['my_app/templates'],
        'APP_DIRS': True,
}]

Then put your override template files under my_app/templates. So the overridden password reset template would be my_app/templates/registration/password_reset_form.html

Let Spring 3 injection take care of this.

Thanks to tsunade21 the easiest way is:

 @RequestMapping(method = RequestMethod.GET)   
 public ModelAndView anyMethodNameGoesHere(Principal principal) {
        final String loggedInUserName = principal.getName();

 }

You can try this.. My own version of it..

funcc() {
while true ; do 
for i in \| \/ \- \\ \| \/ \- \\; do 
  echo -n -e "\r$1  $i  "
sleep 0.5
done  
#echo -e "\r                                                                                      "
[ -f /tmp/print-stat ] && break 2
done
}

funcc "Checking Kubectl" & &>/dev/null
sleep 5
touch /tmp/print-stat
echo -e "\rPrint Success                  "

One way to do this without JS is to use the hover action to reveal a HTML element that is otherwise hidden, see this codepen:

http://codepen.io/c0un7z3r0/pen/LZWXEw

Note that the span that contains the tooltip content is relative to the parent li. The magic is here:

ul#list_of_thrones li > span{
  display:none;
}
ul#list_of_thrones li:hover > span{
  position: absolute;
  display:block;
  ...
}

As you can see, the span is hidden unless the listitem is hovered over, thus revealing the span element, the span can contain as much html as you need. In the codepen attached I have also used a :after element for the arrow but that of course is entirely optional and has only been included in this example for cosmetic purposes.

I hope this helps, I felt compelled to post as all the other answers included JS solutions but the OP asked for a HTML/CSS only solution.

It has a tricky situation: If you submit a post form, then Chrome will open a new tab to send the request. It's right until now, but if it triggers an event to download file(s), this tab will close immediately so that you cannot capture this request in the Dev Tool.

Solution: Before submitting the post form, you need to cut off your network, which makes the request cannot send successfully so that the tab will not be closed. And then you can capture the request message in the Chrome Devtool(Refreshing the new tab if necessary)

Try:

throw new Exception("transction: " + transNbr, E); 

I think it comes from this line in your XML file:

<context:component-scan base-package="org.assessme.com.controller." />

Replace it by:

<context:component-scan base-package="org.assessme.com." />

It is because your Autowired service is not scanned by Spring since it is not in the right package.

Under Ubuntu I had the problem and solved it with

$ sudo apt-get install php5-mcrypt
$ sudo service apache2 reload

The easiest way to block these temporarily for testing purposes is to open up the inspect page in chrome by right-clicking anywhere on the page and clicking inspect or by pressing Ctrl+Shift+j and then going to the networking tab and then reloading the page which will send all the requests your page is supposed to make including that annoying favicon.ico. You can now simply right click the favicon.ico request and click "Block request URL".

All of the above answers are for devs who control the app source code. If you are a sysadmin, who's figuring our load-balancer or proxying configuration and is annoyed by this favicon.ico shenanigans, this simple trick does a better job. This answer is for Chrome, but I think there should be a similar alternative which you would figure out for Firefox/Opera/Tor/any other browser :)

If you don't want to use external libs, then one solution is to recreate the reload method from python 2 for python 3 as below. Use this in the top of the module (assumes python 3.4+).

import sys
if(sys.version_info.major>=3):
    def reload(MODULE):        
        import importlib
        importlib.reload(MODULE)

BTW reload is very much required if you use python files as config files and want to avoid restarts of the application.....

The best source for rationale for a Python addition would be its PEP: PEP 389: argparse - New Command Line Parsing Module, in particular, the section entitled, Why aren't getopt and optparse enough?

I would recommend this (just found via search):

1. http://lunapic.com/editor/?action=load
2. Browse for image to upload OR enter URL of the file (below the image)
   http://i.stack.imgur.com/2gQWg.png
3. Edit menu/Transparent (last one)
4. Click on the red area
5. Behold :) below is your image, it's just white triangle with transparency...
   [dragging the image around in your browser for visibility,
   the gray background and the border is not part of the image]
   
6. File menu/Save Image
   GIF/PNG/ICO image file formats support transparency, JPG doesn't!

Disclaimer: @theTinMan and other Ruby developers often point out not to use sudo when installing gems and point to things like RVM. That's absolutely true when doing Ruby development. Go ahead and use that.

However, many of us just want some binary that happens to be distributed as a gem (e.g. fakes3, cocoapods, xcpretty …). I definitely don't want to bother with managing a separate ruby. Here are your quicker options:

Option 1: Keep using sudo

Using sudo is probably fine if you want these tools to be installed globally.

The problem is that these binaries are installed into /usr/bin, which is off-limits since El Capitan. However, you can install them into /usr/local/bin instead. That's where Homebrew install its stuff, so it probably exists already.

sudo gem install fakes3 -n/usr/local/bin

Gems will be installed into /usr/local/bin and every user on your system can use them if it's in their PATH.

Option 2: Install in your home directory (without sudo)

The following will install gems in ~/.gem and put binaries in ~/bin (which you should then add to your PATH).

gem install fakes3 --user-install -n~/bin

Make it the default

Either way, you can add these parameters to your ~/.gemrc so you don't have to remember them:

gem: -n/usr/local/bin

i.e. echo "gem: -n/usr/local/bin" >> ~/.gemrc

or

gem: --user-install -n~/bin

i.e. echo "gem: --user-install -n~/bin" >> ~/.gemrc

(Tip: You can also throw in --no-document to skip generating Ruby developer documentation.)

I've been playing around with another option that uses blobs. I've managed to get it to download text documents, and I've downloaded PDF's (However they are corrupted).

Using the blob API you will be able to do the following:

$.post(/*...*/,function (result)
{
    var blob=new Blob([result]);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="myFileName.txt";
    link.click();

});

This is IE 10+, Chrome 8+, FF 4+. See https://developer.mozilla.org/en-US/docs/Web/API/URL.createObjectURL

It will only download the file in Chrome, Firefox and Opera. This uses a download attribute on the anchor tag to force the browser to download it.

Justin's example above is very good. But that Primary key need should be stated very clearly. I have seen that code in the wild without the key and the results are bad.

The complaint I get about the Percentile_Cont is that it wont give you an actual value from the dataset. To get to a "median" that is an actual value from the dataset use Percentile_Disc.

SELECT SalesOrderID, OrderQty,
    PERCENTILE_DISC(0.5) 
        WITHIN GROUP (ORDER BY OrderQty)
        OVER (PARTITION BY SalesOrderID) AS MedianCont
FROM Sales.SalesOrderDetail
WHERE SalesOrderID IN (43670, 43669, 43667, 43663)
ORDER BY SalesOrderID DESC

char c=(char)0x2202; String s=""+c;

add this line in your css file:

.classname ul li {
    float: left;
}

An HTML parser should be used for this purpose rather than regular expressions. A Perl program that makes use of HTML::TreeBuilder:

Program

#!/usr/bin/env perl

use strict;
use warnings;

use HTML::TreeBuilder;

my $tree = HTML::TreeBuilder->new_from_file( \*DATA );
my @elements = $tree->look_down(
    sub { defined $_[0]->attr('name') }
);

for (@elements) {
    print $_->attr('name'), "\n";
}

__DATA__
<table name="content_analyzer" primary-key="id">
  <type="global" />
</table>
<table name="content_analyzer2" primary-key="id">
  <type="global" />
</table>
<table name="content_analyzer_items" primary-key="id">
  <type="global" />
</table>

Output

content_analyzer
content_analyzer2
content_analyzer_items

My suggestion for google maps api v3 would be(don't think it can be done more effeciently):

gmap : {
    fitBounds: function(bounds, mapId)
    {
        //incoming: bounds - bounds object/array; mapid - map id if it was initialized in global variable before "var maps = [];"
        if (bounds==null) return false;
        maps[mapId].fitBounds(bounds);
    }
}

In the result u will fit all points in bounds in your map window.

Example works perfectly and u freely can check it here www.zemelapis.lt

SMTP protocol: smtps (port 465) v. msa (port 587)

Ports 465 and 587 are intended for email client to email server communication - sending out email using SMTP protocol.

Port 465 is for smtps
SSL encryption is started automatically before any SMTP level communication.

Port 587 is for msa
It is almost like standard SMTP port. MSA should accept email after authentication (e.g. after SMTP AUTH). It helps to stop outgoing spam when netmasters of DUL ranges can block outgoing connections to SMTP port (port 25).
SSL encryption may be started by STARTTLS command at SMTP level if server supports it and your ISP does not filter server's EHLO reply (reported 2014).

Port 25 is used by MTA to MTA communication (mail server to mail server). It may be used for client to server communication but it is not currently the most recommended. Standard SMTP port accepts email from other mail servers to its "internal" mailboxes without authentication.

[6] was spot on. I had the same problem ie a blank screen where wp-admin should have been Renaming plugins to pluginss let me get back in.

I also had a blank screen for my blog. The solution was to copy up a backup copy of wp-config,php somehow the 'live' wp-config.php had been replaced with a file size of zero.

It seems that it is very important to have an off-line backup The easy way to copy of the files is Filezilla (freeware)

You need a wordpress plugin for database backup - ie to back up all your pages and posts. But the pros will tell you that you need to get a

Easiest solution is to create the column using the correct data type: DATE

For example:

1. Create table:

   create table test_date (mydate date);

2. Insert row:

   insert into test_date values (to_date('01-01-2011','dd-mm-yyyy'));

To get the month and year, do as follows:

select to_char(mydate, 'MM-YYYY') from test_date;

Your result will be as follows: 01-2011

Another cool function to use is "EXTRACT"

select extract(year from mydate) from test_date;

This will return: 2011

Assuming you want the format "(123) 456-7890":

function formatPhoneNumber(phoneNumberString) {
  var cleaned = ('' + phoneNumberString).replace(/\D/g, '')
  var match = cleaned.match(/^(\d{3})(\d{3})(\d{4})$/)
  if (match) {
    return '(' + match[1] + ') ' + match[2] + '-' + match[3]
  }
  return null
}

Here's a version that allows the optional +1 international code:

function formatPhoneNumber(phoneNumberString) {
  var cleaned = ('' + phoneNumberString).replace(/\D/g, '')
  var match = cleaned.match(/^(1|)?(\d{3})(\d{3})(\d{4})$/)
  if (match) {
    var intlCode = (match[1] ? '+1 ' : '')
    return [intlCode, '(', match[2], ') ', match[3], '-', match[4]].join('')
  }
  return null
}
formatPhoneNumber('+12345678900') // => "+1 (234) 567-8900"
formatPhoneNumber('2345678900')   // => "(234) 567-8900"

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

I needed the same concept to compress sequentially several directories or files from a certain folder. I have solved using awk to parsel the list from ls and to avoid the problem of blank space in the name.

source="/xxx/xxx"
dest="/yyy/yyy"

n_max=`ls . | wc -l`

echo "Loop over items..."
i=1
while [ $i -le $n_max ];do
item=`ls . | awk 'NR=='$i'' `
echo "File selected for compression: $item"
tar -cvzf $dest/"$item".tar.gz "$item"
i=$(( i + 1 ))
done
echo "Done!!!"

what do you think?

FailedPreconditionError: Attempting to use uninitialized value is one of the most frequent errors related to tensorflow. From official documentation, FailedPreconditionError

This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.

In your case the error even explains what variable was not initialized: Attempting to use uninitialized value Variable_1. One of the TF tutorials explains a lot about variables, their creation/initialization/saving/loading

Basically to initialize the variable you have 3 options:

• initialize all global variables with tf.global_variables_initializer()
• initialize variables you care about with tf.variables_initializer(list_of_vars). Notice that you can use this function to mimic global_variable_initializer: tf.variable_initializers(tf.global_variables())
• initialize only one variable with var_name.initializer

I almost always use the first approach. Remember you should put it inside a session run. So you will get something like this:

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())

If your are curious about more information about variables, read this documentation to know how to report_uninitialized_variables and check is_variable_initialized.

Jquery Datepicker defaultDate ONLY set the default date that you chose on the calendar that pops up when you click on your field. If you want the default date to APPEAR on your input before the user clicks on the field you should give a val() to your field. Something like this:

$("#searchDateFrom").datepicker({ defaultDate: "-1y -1m -6d" });
$("#searchDateFrom").val((date.getMonth()) + '/' + (date.getDate() - 6) + '/' + (date.getFullYear() - 1));

Ok, solved it myself;

def sout = new StringBuilder(), serr = new StringBuilder()
def proc = 'ls /badDir'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println "out> $sout\nerr> $serr"

displays:

out> err> ls: cannot access /badDir: No such file or directory

You are passing a dictionary to a function that expects a string.

This syntax:

{"('Hello',)": 6, "('Hi',)": 5}

is both a valid Python dictionary literal and a valid JSON object literal. But loads doesn't take a dictionary; it takes a string, which it then interprets as JSON and returns the result as a dictionary (or string or array or number, depending on the JSON, but usually a dictionary).

If you pass this string to loads:

'''{"('Hello',)": 6, "('Hi',)": 5}'''

then it will return a dictionary that looks a lot like the one you are trying to pass to it.

You could also exploit the similarity of JSON object literals to Python dictionary literals by doing this:

json.loads(str({"('Hello',)": 6, "('Hi',)": 5}))

But in either case you would just get back the dictionary that you're passing in, so I'm not sure what it would accomplish. What's your goal?

Here is a flexible approach, it can be used in all cases, in particular:

1. to affect only one column, or
2. the dataframe has been obtained from applying previous operations (e.g. not immediately opening a file, or creating a new data frame).

First, un-factorize a string using the as.character function, and, then, re-factorize with the as.factor (or simply factor) function:

fixed <- data.frame("Type" = character(3), "Amount" = numeric(3))

# Un-factorize (as.numeric can be use for numeric values)
#              (as.vector  can be use for objects - not tested)
fixed$Type <- as.character(fixed$Type)
fixed[1, ] <- c("lunch", 100)

# Re-factorize with the as.factor function or simple factor(fixed$Type)
fixed$Type <- as.factor(fixed$Type)

Note also that if you have wordpress just scroll down to the bottom of the webpage when in edit mode, and select "featured image" (bottom right side of screen).

Go to Nuget package manager and download Nunit Adapter as follow.

This is happening due to the fact that the logging level of your logger is set to 'error' - therefore you will only see error messages or above this level in terms of severity so this is why you also see the 'fatal' message.

If you set the logging level to 'debug' on your logger in your log4j.xml you should see all messages.

Have a look at the log4j introduction for explaination.

Think I found the correct way to do it using ngx-bootstrap. First import following classes:

import { ViewChild } from '@angular/core';
import { BsModalService, ModalDirective } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/bs-modal-ref.service';

Inside the class implementation of your component add a @ViewCild property, a function to open the modal and do not forget to setup modalService as a private property inside the components class constructor:

@ViewChild('editSomething') editSomethingModal : TemplateRef<any>;
...

modalRef: BsModalRef;
openModal(template: TemplateRef<any>) {
  this.modalRef = this.modalService.show(template);
}
...
constructor(
private modalService: BsModalService) { }

The 'editSomething' part of the @ViewChild declaration refers to the component template file and its modal template implementation (#editSomething):

...
<ng-template #editSomething>
  <div class="modal-header">
  <h4 class="modal-title pull-left">Edit ...</h4>
  <button type="button" class="close pull-right" aria-label="Close" 
   (click)="modalRef.hide()">
    <span aria-hidden="true">&times;</span>
  </button>
  </div>

  <div class="modal-body">
    ...
  </div>


  <div class="modal-footer">
    <button type="button" class="btn btn-default"
        (click)="modalRef.hide()"
        >Close</button>
  </div>
</ng-template>

And finaly call the method to open the modal wherever you want like so:

console.log(this.editSomethingModal);
this.openModal( this.editSomethingModal );

this.editSomethingModal is a TemplateRef that could be shown by the ModalService.

Et voila! The modal defined in your component template file is shown by a call from inside your component class implementation. In my case I used this to show a modal from inside an event handler.

Drop the quotes:

List<Object> bugs = JsonPath.read(githubIssues, "$..labels[?(@.name==bug)]");

See also this Json Path Example page

It stores an exact, versioned dependency tree rather than using starred versioning like package.json itself (e.g. 1.0.*). This means you can guarantee the dependencies for other developers or prod releases, etc. It also has a mechanism to lock the tree but generally will regenerate if package.json changes.

From the npm docs:

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

This file is intended to be committed into source repositories, and serves various purposes:

Describe a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.

Provide a facility for users to "time-travel" to previous states of node_modules without having to commit the directory itself.

To facilitate greater visibility of tree changes through readable source control diffs.

And optimize the installation process by allowing npm to skip repeated metadata resolutions for previously-installed packages."

Edit

To answer jrahhali's question below about just using the package.json with exact version numbers. Bear in mind that your package.json contains only your direct dependencies, not the dependencies of your dependencies (sometimes called nested dependencies). This means with the standard package.json you can't control the versions of those nested dependencies, referencing them directly or as peer dependencies won't help as you also don't control the version tolerance that your direct dependencies define for these nested dependencies.

Even if you lock down the versions of your direct dependencies you cannot 100% guarantee that your full dependency tree will be identical every time. Secondly you might want to allow non-breaking changes (based on semantic versioning) of your direct dependencies which gives you even less control of nested dependencies plus you again can't guarantee that your direct dependencies won't at some point break semantic versioning rules themselves.

The solution to all this is the lock file which as described above locks in the versions of the full dependency tree. This allows you to guarantee your dependency tree for other developers or for releases whilst still allowing testing of new dependency versions (direct or indirect) using your standard package.json.

NB. The previous shrink wrap json did pretty much the same thing but the lock file renames it so that it's function is clearer. If there's already a shrink wrap file in the project then this will be used instead of any lock file.

Ctrl-/ will insert // style commenting, for javascript, etc
Ctrl-/ will insert <!-- --> comments for HTML,
Ctrl-/ will insert # comments for Ruby,
..etc

But does not work perfectly on HTML <script> tags.

HTML <script> ..blah.. </script> tags:
Ctrl-/ twice (ie Ctrl-/Ctrl-/) will effectively comment out the line:

• The first Ctrl-/ adds // to the beginning of the line,
  which comments out the script tag, but adds "//" text to your webpage.
• The second Ctrl-/ then surrounds that in <!-- --> style comments, which accomplishes the task.

Ctrl--Shift-/ does not produce multi-line comments on HTML (or even single line comments), but does
add /* */ style multi-line comments in Javascript, text, and other file formats.

--

[I added as a new answer since I could not add comments.
I included this info because this is the info I was looking for, and this is the only related StackOverflow page from my search results.
I since discovered the / / trick for HTML script tags and decided to share this additional information, since it requires a slight variation of the usual catch-all (and reported above)
/ and Ctrl--Shift-/ method of commenting out one's code in sublime.]

Actually I think using plain slices is the best solution in this case:

for i in range(0, len(data), 100):
    chunk = data[i:i + 100]
    ...

If you want to avoid copying the slices, you could use itertools.islice(), but it doesn't seem to be necessary here.

The itertools() documentation also contains the famous "grouper" pattern:

def grouper(n, iterable, fillvalue=None):
    "grouper(3, 'ABCDEFG', 'x') --> ABC DEF Gxx"
    args = [iter(iterable)] * n
    return izip_longest(fillvalue=fillvalue, *args)

You would need to modify it to treat the last chunk correctly, so I think the straight-forward solution using plain slices is preferable.

As others have said, this isn't something you'd want to be doing in CSS. You can fudge it with absolute positioning and strange margins, but it's just not a robust solution. The best option in your case would be to turn to javascript. In jQuery, this is a very simple task:

$('#secondDiv').insertBefore('#firstDiv');

or more generically:

$('.swapMe').each(function(i, el) {
    $(el).insertBefore($(el).prev());
});

Building upon the psutil solution mentioned by Joe (only works for checking local ports):

import psutil
1111 in [i.laddr.port for i in psutil.net_connections()]

returns True if port 1111 currently used.

psutil is not part of python stdlib, so you'd need to pip install psutil first. It also needs python headers to be available, so you need something like python-devel

I think you want this:

select *
from dbo.table
where DATALENGTH(column_name) = 3

"not equal" So in this case, $RESULT is tested to not be equal to zero.

However, the test is done numerically, not alphabetically:

n1 -ne n2     True if the integers n1 and n2 are not algebraically equal.

compared to:

s1 != s2      True if the strings s1 and s2 are not identical.

Added a little bit more functionality to the example of Aravind Voggu:

def progressBar(name, value, endvalue, bar_length = 50, width = 20):
        percent = float(value) / endvalue
        arrow = '-' * int(round(percent*bar_length) - 1) + '>'
        spaces = ' ' * (bar_length - len(arrow))
        sys.stdout.write("\r{0: <{1}} : [{2}]{3}%".format(\
                         name, width, arrow + spaces, int(round(percent*100))))
        sys.stdout.flush()
        if value == endvalue:     
             sys.stdout.write('\n\n')

Now you are able to generate multiple progressbars without replacing the previous one.

I've also added name as a value with a fixed width.

For two loops and two times the use of progressBar() the result will look like:

It is quite normal to organize JavaScript program modular into several files and to call child-modules from the main js module.

The thing is JavaScript doesn't provide this. Not even today in latest browser versions of Chrome and FF.

But, is there any keyword in JavaScript to call another JavaScript module?

This question may be a total collapse of the world for many because the answer is No.

In ES5 ( released in 2009 ) JavaScript had no keywords like import, include, or require.

ES6 saves the day ( released in 2015 ) proposing the import keyword ( https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Statements/import ), but no browser implements this.

If you use Babel 6.18.0 and transpile with ES2015 option only

import myDefault from "my-module";

you will get require again.

"use strict";
var _myModule = require("my-module");
var _myModule2 = _interopRequireDefault(_myModule);
function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }

This is because require means the module will be loaded from Node.js. Node.js will handle everything from system level file read to wrapping functions into the module.

Because in JavaScript functions are the only wrappers to represent the modules.

I'm a lot confused about CommonJS and AMD?

Both CommonJS and AMD are just two different techniques how to overcome the JavaScript "defect" to load modules smart.

Here is your relief for the problem :

I have a problem of running different versions of STS this morning, the application crash with the similar way as the question did.

links are :

a fATAL ERROR JAVA THIS ONE IS GREAT LOTS OF USER!

a fATAL ERROR JAVA 2

Okay, after that here's what I found out to casue this case and why it happens as general advise.

1. Most of the time, check that if you have installed, updated recently on Ubunu and Windows there are libraries like libsoup in linux which were the casuse of my crash.

2. Check also for a new hardware problem and try to investigate the Logfile which STS or Java generated and also syslog in linux by

   tail - f /var/lib/messages or some other file
   

Then by carfully looking at those files the one you have the crash log for ... you can really solve the issue as follows:

sudo unlink /usr/lib/i386-linux-gnu/libsoup-2.4.so.1

or

sudo unlink /usr/lib/x86_64-linux-gnu/libsoup-2.4.so.1

Done !! Cheers!!

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

No this data is not exposed. The only data that is available is what is exposed through the HTTP request which might include their OS and other such information. But certainly not machine name.

First, bootstrap-theme.css is nothing else but equivalent of Bootstrap 2.x style in Bootstrap 3. If you really want to use it, just add it ALONG with bootstrap.css (minified version will work too).

Yes, they have deprecated the previous buildSessionFactory API, and it's quite easy to do well.. you can do something like this..

EDIT : ServiceRegistryBuilder is deprecated. you must use StandardServiceRegistryBuilder

public void testConnection() throws Exception {

            logger.info("Trying to create a test connection with the database.");
            Configuration configuration = new Configuration();
            configuration.configure("hibernate_sp.cfg.xml");
            StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
            SessionFactory sessionFactory = configuration.buildSessionFactory(ssrb.build());
            Session session = sessionFactory.openSession();
            logger.info("Test connection with the database created successfuly.");
    }

For more reference and in depth detail, you can check the hibernate's official test case at https://github.com/hibernate/hibernate-orm/blob/master/hibernate-testing/src/main/java/org/hibernate/testing/junit4/BaseCoreFunctionalTestCase.java function (buildSessionFactory()).

<script type="text/javascript">
document.getElementById('button1').onChange = function () {

Great! The solution given above worked for me. Had the same problem with a GET call.

 method: 'GET',
 data: '',
 headers: {
        "Content-Type": "application/json"
 }

First add following lines in ~/.bashrc file

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

then open terminal and source the nvm.sh script

source ~/.nvm/nvm.sh

for OS's that support select:

import select

# your code

select.select([], [], [])

Installing the Chrome extension IE Tab did the job for me.

It has the ability to auto-detect URLs so whenever I browse to our SharePoint it emulates Internet Explorer. Finally I can open Office documents directly from Chrome.

You can install IETab for FireFox too.

An example with a little less stringified html:

var container = $('#my-container'),
  table = $('<table>');

users.forEach(function(user) {
  var tr = $('<tr>');
  ['ID', 'Name', 'Address'].forEach(function(attr) {
    tr.append('<td>' + user[attr] + '</td>');
  });
  table.append(tr);
});

container.append(table);

The traditional method for checking for packages in Python is "it's better to beg forgiveness than ask permission", or rather, "it's better to catch an exception than test a condition."

try:
    import numpy
    HAS_NUMPY = True
except ImportError:
    HAS_NUMPY = False

Use varchar instead of VAR_CHAR and omit the comma in the last line i.e.phone INT NOT NULL );. The last line during creating table is kept "comma free". Ex:- CREATE TABLE COMPUTER ( Model varchar(50) ); Here, since we have only one column ,that's why there is no comma used during entire code.

It is written here that "By default, Android Studio 2.2 and the Android Plugin for Gradle 2.2 sign your app using both APK Signature Scheme v2 and the traditional signing scheme, which uses JAR signing."

As it seems that these new checkboxes appeared with Android 2.3, I understand that my previous versions of Android Studio (at least the 2.2) did sign with both signatures. So, to continue as I did before, I think that it is better to check both checkboxes.

EDIT March 31st, 2017 : submitted several apps with both signatures => no problem :)

1. Data contract: It specifies that your entity class is ready for Serialization process.

2. Data members: It specifies that the particular field is part of the data contract and it can be serialized.

EDIT: this solution is now in the original answer too.

The accepted answer is not quite correct. You should not be using the position() function since it is relative to the parent. If you are doing global positioning(in most cases?) you should only add the offset top with the outerheight like so:

var actualBottom = $(selector).offset().top + $(selector).outerHeight(true);

The docs http://api.jquery.com/offset/

Adding local classes, lambdas and the toString() method to complete the previous two answers. Further, I add arrays of lambdas and arrays of anonymous classes (which do not make any sense in practice though):

package com.example;

public final class TestClassNames {
    private static void showClass(Class<?> c) {
        System.out.println("getName():          " + c.getName());
        System.out.println("getCanonicalName(): " + c.getCanonicalName());
        System.out.println("getSimpleName():    " + c.getSimpleName());
        System.out.println("toString():         " + c.toString());
        System.out.println();
    }

    private static void x(Runnable r) {
        showClass(r.getClass());
        showClass(java.lang.reflect.Array.newInstance(r.getClass(), 1).getClass()); // Obtains an array class of a lambda base type.
    }

    public static class NestedClass {}

    public class InnerClass {}

    public static void main(String[] args) {
        class LocalClass {}
        showClass(void.class);
        showClass(int.class);
        showClass(String.class);
        showClass(Runnable.class);
        showClass(SomeEnum.class);
        showClass(SomeAnnotation.class);
        showClass(int[].class);
        showClass(String[].class);
        showClass(NestedClass.class);
        showClass(InnerClass.class);
        showClass(LocalClass.class);
        showClass(LocalClass[].class);
        Object anonymous = new java.io.Serializable() {};
        showClass(anonymous.getClass());
        showClass(java.lang.reflect.Array.newInstance(anonymous.getClass(), 1).getClass()); // Obtains an array class of an anonymous base type.
        x(() -> {});
    }
}

enum SomeEnum {
   BLUE, YELLOW, RED;
}

@interface SomeAnnotation {}

So, here are the rules. First, lets start with primitive types and void:

1. If the class object represents a primitive type or void, all the four methods simply returns its name.

Now the rules for the getName() method:

2. Every non-lambda and non-array class or interface (i.e, top-level, nested, inner, local and anonymous) has a name (which is returned by getName()) that is the package name followed by a dot (if there is a package), followed by the name of its class-file as generated by the compiler (whithout the suffix .class). If there is no package, it is simply the name of the class-file. If the class is an inner, nested, local or anonymous class, the compiler should generate at least one $ in its class-file name. Note that for anonymous classes, the class name would end with a dollar-sign followed by a number.
3. Lambda class names are generally unpredictable, and you shouldn't care about they anyway. Exactly, their name is the name of the enclosing class, followed by $$Lambda$, followed by a number, followed by a slash, followed by another number.
4. The class descriptor of the primitives are Z for boolean, B for byte, S for short, C for char, I for int, J for long, F for float and D for double. For non-array classes and interfaces the class descriptor is L followed by what is given by getName() followed by ;. For array classes, the class descriptor is [ followed by the class descriptor of the component type (which may be itself another array class).
5. For array classes, the getName() method returns its class descriptor. This rule seems to fail only for array classes whose the component type is a lambda (which possibly is a bug), but hopefully this should not matter anyway because there is no point even on the existence of array classes whose component type is a lambda.

Now, the toString() method:

6. If the class instance represents an interface (or an annotation, which is a special type of interface), the toString() returns "interface " + getName(). If it is a primitive, it returns simply getName(). If it is something else (a class type, even if it is a pretty weird one), it returns "class " + getName().

The getCanonicalName() method:

7. For top-level classes and interfaces, the getCanonicalName() method returns just what the getName() method returns.
8. The getCanonicalName() method returns null for anonymous or local classes and for array classes of those.
9. For inner and nested classes and interfaces, the getCanonicalName() method returns what the getName() method would replacing the compiler-introduced dollar-signs by dots.
10. For array classes, the getCanonicalName() method returns null if the canonical name of the component type is null. Otherwise, it returns the canonical name of the component type followed by [].

The getSimpleName() method:

11. For top-level, nested, inner and local classes, the getSimpleName() returns the name of the class as written in the source file.
12. For anonymous classes the getSimpleName() returns an empty String.
13. For lambda classes the getSimpleName() just returns what the getName() would return without the package name. This do not makes much sense and looks like a bug for me, but there is no point in calling getSimpleName() on a lambda class to start with.
14. For array classes the getSimpleName() method returns the simple name of the component class followed by []. This have the funny/weird side-effect that array classes whose component type is an anonymous class have just [] as their simple names.

To determine if you are at the end of your custom ScrollView you could also use a member variable and store the last y-position. Then you can compare the last y-position with the current scroll position.

private int scrollViewPos;

...

@Override
public void onScrollChanged(ScrollViewExt scrollView, int x, int y, int oldx, int oldy) {

   //reached end of scrollview
   if (y > 0 && scrollViewPos == y){
      //do something
   }

   scrollViewPos = y;
}

While technically correct, the other answers would benefit from an explanation of Angular's URL-to-route matching. I don't think you can fully (pardon the pun) understand what pathMatch: full does if you don't know how the router works in the first place.

Let's first define a few basic things. We'll use this URL as an example: /users/james/articles?from=134#section.

1. It may be obvious but let's first point out that query parameters (?from=134) and fragments (#section) do not play any role in path matching. Only the base url (/users/james/articles) matters.

2. Angular splits URLs into segments. The segments of /users/james/articles are, of course, users, james and articles.

3. The router configuration is a tree structure with a single root node. Each Route object is a node, which may have children nodes, which may in turn have other children or be leaf nodes.

The goal of the router is to find a router configuration branch, starting at the root node, which would match exactly all (!!!) segments of the URL. This is crucial! If Angular does not find a route configuration branch which could match the whole URL - no more and no less - it will not render anything.

E.g. if your target URL is /a/b/c but the router is only able to match either /a/b or /a/b/c/d, then there is no match and the application will not render anything.

Finally, routes with redirectTo behave slightly differently than regular routes, and it seems to me that they would be the only place where anyone would really ever want to use pathMatch: full. But we will get to this later.

Default (prefix) path matching

The reasoning behind the name prefix is that such a route configuration will check if the configured path is a prefix of the remaining URL segments. However, the router is only able to match full segments, which makes this naming slightly confusing.

Anyway, let's say this is our root-level router configuration:

const routes: Routes = [
  {
    path: 'products',
    children: [
      {
        path: ':productID',
        component: ProductComponent,
      },
    ],
  },
  {
    path: ':other',
    children: [
      {
        path: 'tricks',
        component: TricksComponent,
      },
    ],
  },
  {
    path: 'user',
    component: UsersonComponent,
  },
  {
    path: 'users',
    children: [
      {
        path: 'permissions',
        component: UsersPermissionsComponent,
      },
      {
        path: ':userID',
        children: [
          {
            path: 'comments',
            component: UserCommentsComponent,
          },
          {
            path: 'articles',
            component: UserArticlesComponent,
          },
        ],
      },
    ],
  },
];

Note that every single Route object here uses the default matching strategy, which is prefix. This strategy means that the router iterates over the whole configuration tree and tries to match it against the target URL segment by segment until the URL is fully matched. Here's how it would be done for this example:

1. Iterate over the root array looking for a an exact match for the first URL segment - users.
2. 'products' !== 'users', so skip that branch. Note that we are using an equality check rather than a .startsWith() or .includes() - only full segment matches count!
3. :other matches any value, so it's a match. However, the target URL is not yet fully matched (we still need to match james and articles), thus the router looks for children.

• The only child of :other is tricks, which is !== 'james', hence not a match.

4. Angular then retraces back to the root array and continues from there.
5. 'user' !== 'users, skip branch.
6. 'users' === 'users - the segment matches. However, this is not a full match yet, thus we need to look for children (same as in step 3).

• 'permissions' !== 'james', skip it.
• :userID matches anything, thus we have a match for the james segment. However this is still not a full match, thus we need to look for a child which would match articles.
  1. We can see that :userID has a child route articles, which gives us a full match! Thus the application renders UserArticlesComponent.

Full URL (full) matching

Example 1

Imagine now that the users route configuration object looked like this:

{
  path: 'users',
  component: UsersComponent,
  pathMatch: 'full',
  children: [
    {
      path: 'permissions',
      component: UsersPermissionsComponent,
    },
    {
      path: ':userID',
      component: UserComponent,
      children: [
        {
          path: 'comments',
          component: UserCommentsComponent,
        },
        {
          path: 'articles',
          component: UserArticlesComponent,
        },
      ],
    },
  ],
}

Note the usage of pathMatch: full. If this were the case, steps 1-5 would be the same, however step 6 would be different:

6. 'users' !== 'users/james/articles - the segment does not match because the path configuration users with pathMatch: full does not match the full URL, which is users/james/articles.
7. Since there is no match, we are skipping this branch.
8. At this point we reached the end of the router configuration without having found a match. The application renders nothing.

Example 2

What if we had this instead:

{
  path: 'users/:userID',
  component: UsersComponent,
  pathMatch: 'full',
  children: [
    {
      path: 'comments',
      component: UserCommentsComponent,
    },
    {
      path: 'articles',
      component: UserArticlesComponent,
    },
  ],
}

users/:userID with pathMatch: full matches only users/james thus it's a no-match once again, and the application renders nothing.

Example 3

Let's consider this:

{
  path: 'users',
  children: [
    {
      path: 'permissions',
      component: UsersPermissionsComponent,
    },
    {
      path: ':userID',
      component: UserComponent,
      pathMatch: 'full',
      children: [
        {
          path: 'comments',
          component: UserCommentsComponent,
        },
        {
          path: 'articles',
          component: UserArticlesComponent,
        },
      ],
    },
  ],
}

In this case:

6. 'users' === 'users - the segment matches, but james/articles still remains unmatched. Let's look for children.

• 'permissions' !== 'james' - skip.
• :userID' can only match a single segment, which would be james. However, it's a pathMatch: full route, and it must match james/articles (the whole remaining URL). It's not able to do that and thus it's not a match (so we skip this branch)!

7. Again, we failed to find any match for the URL and the application renders nothing.

As you may have noticed, a pathMatch: full configuration is basically saying this:

Ignore my children and only match me. If I am not able to match all of the remaining URL segments myself, then move on.

Redirects

Any Route which has defined a redirectTo will be matched against the target URL according to the same principles. The only difference here is that the redirect is applied as soon as a segment matches. This means that if a redirecting route is using the default prefix strategy, a partial match is enough to cause a redirect. Here's a good example:

const routes: Routes = [
  {
    path: 'not-found',
    component: NotFoundComponent,
  },
  {
    path: 'users',
    redirectTo: 'not-found',
  },
  {
    path: 'users/:userID',
    children: [
      {
        path: 'comments',
        component: UserCommentsComponent,
      },
      {
        path: 'articles',
        component: UserArticlesComponent,
      },
    ],
  },
];

For our initial URL (/users/james/articles), here's what would happen:

1. 'not-found' !== 'users' - skip it.
2. 'users' === 'users' - we have a match.
3. This match has a redirectTo: 'not-found', which is applied immediately.
4. The target URL changes to not-found.
5. The router begins matching again and finds a match for not-found right away. The application renders NotFoundComponent.

Now consider what would happen if the users route also had pathMatch: full:

const routes: Routes = [
  {
    path: 'not-found',
    component: NotFoundComponent,
  },
  {
    path: 'users',
    pathMatch: 'full',
    redirectTo: 'not-found',
  },
  {
    path: 'users/:userID',
    children: [
      {
        path: 'comments',
        component: UserCommentsComponent,
      },
      {
        path: 'articles',
        component: UserArticlesComponent,
      },
    ],
  },
];

1. 'not-found' !== 'users' - skip it.
2. users would match the first segment of the URL, but the route configuration requires a full match, thus skip it.
3. 'users/:userID' matches users/james. articles is still not matched but this route has children.

• We find a match for articles in the children. The whole URL is now matched and the application renders UserArticlesComponent.

Empty path (path: '')

The empty path is a bit of a special case because it can match any segment without "consuming" it (so it's children would have to match that segment again). Consider this example:

const routes: Routes = [
  {
    path: '',
    children: [
      {
        path: 'users',
        component: BadUsersComponent,
      }
    ]
  },
  {
    path: 'users',
    component: GoodUsersComponent,
  },
];

Let's say we are trying to access /users:

• path: '' will always match, thus the route matches. However, the whole URL has not been matched - we still need to match users!
• We can see that there is a child users, which matches the remaining (and only!) segment and we have a full match. The application renders BadUsersComponent.

Now back to the original question

The OP used this router configuration:

const routes: Routes = [
  {
    path: 'welcome',
    component: WelcomeComponent,
  },
  {
    path: '',
    redirectTo: 'welcome',
    pathMatch: 'full',
  },
  {
    path: '**',
    redirectTo: 'welcome',
    pathMatch: 'full',
  },
];

If we are navigating to the root URL (/), here's how the router would resolve that:

1. welcome does not match an empty segment, so skip it.
2. path: '' matches the empty segment. It has a pathMatch: 'full', which is also satisfied as we have matched the whole URL (it had a single empty segment).
3. A redirect to welcome happens and the application renders WelcomeComponent.

What if there was no pathMatch: 'full'?

Actually, one would expect the whole thing to behave exactly the same. However, Angular explicitly prevents such a configuration ({ path: '', redirectTo: 'welcome' }) because if you put this Route above welcome, it would theoretically create an endless loop of redirects. So Angular just throws an error, which is why the application would not work at all! (https://angular.io/api/router/Route#pathMatch)

Actually, this does not make too much sense to me because Angular also has implemented a protection against such endless redirects - it only runs a single redirect per routing level! This would stop all further redirects (as you'll see in the example below).

What about path: '**'?

path: '**' will match absolutely anything (af/frewf/321532152/fsa is a match) with or without a pathMatch: 'full'.

Also, since it matches everything, the root path is also included, which makes { path: '', redirectTo: 'welcome' } completely redundant in this setup.

Funnily enough, it is perfectly fine to have this configuration:

const routes: Routes = [
  {
    path: '**',
    redirectTo: 'welcome'
  },
  {
    path: 'welcome',
    component: WelcomeComponent,
  },
];

If we navigate to /welcome, path: '**' will be a match and a redirect to welcome will happen. Theoretically this should kick off an endless loop of redirects but Angular stops that immediately (because of the protection I mentioned earlier) and the whole thing works just fine.

Imagine it this way: a mail truck can carry 5000 sheets of paper each trip so It's bandwidth is 5000. Does that mean it can carry 5000 letter each trip? Well, theoretically, if each letter didn't need an envelope telling us where it was coming from, going too, and possessing proof of payment (Envelope = Protocol Headers and Footers). But they do, so each letter (1 sheet of paper) requires an envelope (= to about 1 sheet of paper) to get it to it's destination. So in the worst case scenario (all envelopes only have one page letters), the truck would carry only 2500 sheets Throughput (Data that we want to send from source>destination, THE LETTERS) and would have 2500 sheets Overhead (Headers/Footer that we need to get the letter from source>destination but that the recipient won't be reading, THE ENVELOPES). The Throughput, 2500 Letters + the Overhead, 2500 Envelopes = Bandwidth, 5000 sheets of paper. Bigger letters (4 pages) still only require 1 envelope so that would move the ratio of Throughput to Overhead higher (i.e. Jumbo Frames) and make it more efficient, so if all the letters were 4 page letters throughput would change to 4000, and overhead would reduce to 1000, together equaling the 5000 Bandwidth of the truck.
