Instead of wasting your time to design a JFrame just to display a error message, you can use an JOptionPane which is by default modal:

import javax.swing.JOptionPane;

public class Main {

    public static void main(String[] args) {
        JOptionPane.showMessageDialog(null, "Your message goes here!","Message", JOptionPane.ERROR_MESSAGE);
    }
}

P.S. Stop using Windowbuilder if you want to learn Swing.

In some extreme cases, your only way around recurring build failures is by running:

docker system prune

The command will ask you for your confirmation:

WARNING! This will remove:
    - all stopped containers
    - all volumes not used by at least one container
    - all networks not used by at least one container
    - all images without at least one container associated to them
Are you sure you want to continue? [y/N]

This is of course not a direct answer to the question, but might save some lives... It did save mine.

Use win APIs in your main function:

1. RegisterClassEx() note: you have to provide a pointer to a function (usually called WndProc) which handles windows messages such as WM_CREATE, WM_COMMAND etc
2. CreateWindowEx()
3. ShowWindow()
4. UpdateWindow()

Then write another function which handles win's messages (mentioned in #1). When you receive the message WM_CREATE you have to call CreateWindow(). The class is what control is that window, for example "edit" is a text box and "button" is a.. button :). You have to specify an ID for each control (of your choice but unique among all). CreateWindow() returns a handle to that control, which needs to be memorized. When the user clicks on a control you receive the WM_COMMAND message with the ID of that control. Here you can handle that event. You might find useful SetWindowText() and GetWindowText() which allows you to set/get the text of any control.
You will need only the win32 SDK. You can get it here.

This may help you.

$today = date("m-d-Y H:i:s");
$thisMonth =date("m");
$thisYear = date("y");
$expectedDate = ($thisMonth+1)."-08-$thisYear 23:58:00";


if (strtotime($expectedDate) > strtotime($today)) {
    echo "Expected date is greater then current date";
    return ;
} else
{
 echo "Expected date is lesser then current date";
}

I have no knowledge about DateTime but all I can do is this:

using System;
                    
public class Program
{
    public static int getAge(int month, int day, int year) {
        DateTime today = DateTime.Today;
        int currentDay = today.Day;
        int currentYear = today.Year;
        int currentMonth = today.Month;
        int age = 0;
        if (currentMonth < month) {
            age -= 1;
        } else if (currentMonth == month) {
            if (currentDay < day) {
                age -= 1;
            }
        }
        currentYear -= year;
        age += currentYear;
        return age;
    }
    public static void Main()
    {
        int ageInYears = getAge(8, 10, 2007);
        Console.WriteLine(ageInYears);
    }
}

A little confusing, but looking at the code more carefully, it will all make sense.

This is fairly easy, using marshalling.

Top of file

using System.Runtime.InteropServices

Function

byte[] getBytes(CIFSPacket str) {
    int size = Marshal.SizeOf(str);
    byte[] arr = new byte[size];

    IntPtr ptr = Marshal.AllocHGlobal(size);
    Marshal.StructureToPtr(str, ptr, true);
    Marshal.Copy(ptr, arr, 0, size);
    Marshal.FreeHGlobal(ptr);
    return arr;
}

And to convert it back:

CIFSPacket fromBytes(byte[] arr) {
    CIFSPacket str = new CIFSPacket();

    int size = Marshal.SizeOf(str);
    IntPtr ptr = Marshal.AllocHGlobal(size);

    Marshal.Copy(arr, 0, ptr, size);

    str = (CIFSPacket)Marshal.PtrToStructure(ptr, str.GetType());
    Marshal.FreeHGlobal(ptr);

    return str;
}

In your structure, you will need to put this before a string

[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 100)]
public string Buffer;

And make sure SizeConst is as big as your biggest possible string.

And you should probably read this: http://msdn.microsoft.com/en-us/library/4ca6d5z7.aspx

As answered by others, there's a limit on url size with get, and files can be submitted with post only.

I'd like to add that one can add things to a database with a get and perform actions with a post. When a script receives a post or a get, it can do whatever the author wants it to do. I believe the lack of understanding comes from the wording the book chose or how you read it.

A script author should use posts to change the database and use get only for retrieval of information.

Scripting languages provided many means with which to access the request. For example, PHP allows the use of $_REQUEST to retrieve either a post or a get. One should avoid this in favor of the more specific $_GET or $_POST.

In web programming, there's a lot more room for interpretation. There's what one should and what one can do, but which one is better is often up for debate. Luckily, in this case, there is no ambiguity. You should use posts to change data, and you should use get to retrieve information.

If you don't want to use the OWIN startup, this is what you should add to your web.config file:

Under AppSettings add the following line:

    <add key="owin:AutomaticAppStartup" value="false" />

This is how it should look like in your web.config:

  <appSettings>
    <add key="owin:AutomaticAppStartup" value="false" />
  </appSettings>

Just to add my results, also using Matplotlib.

.eps made all my text bold and removed transparency. .svg gave me high-resolution pictures that actually looked like my graph.

import matplotlib.pyplot as plt
fig, ax = plt.subplots()
# Do the plot code
fig.savefig('myimage.svg', format='svg', dpi=1200)

I used 1200 dpi because a lot of scientific journals require images in 1200 / 600 / 300 dpi, depending on what the image is of. Convert to desired dpi and format in GIMP or Inkscape.

Obviously the dpi doesn't matter since .svg are vector graphics and have "infinite resolution".

As a latest update to android in 2015, Google has included percent support library

com.android.support:percent:23.1.0

You can refer to this site for example of using it

https://github.com/JulienGenoud/android-percent-support-lib-sample

Gradle:

dependencies {
    compile 'com.android.support:percent:22.2.0'
}

In the layout:

<android.support.percent.PercentRelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <View
        android:id="@+id/top_left"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_alignParentTop="true"
        android:background="#ff44aacc"
        app:layout_heightPercent="20%"
        app:layout_widthPercent="70%" />

    <View
        android:id="@+id/top_right"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_alignParentTop="true"
        android:layout_toRightOf="@+id/top_left"
        android:background="#ffe40000"
        app:layout_heightPercent="20%"
        app:layout_widthPercent="30%" />


    <View
        android:id="@+id/bottom"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_below="@+id/top_left"
        android:background="#ff00ff22"
        app:layout_heightPercent="80%" />
</android.support.percent.PercentRelativeLayout>

Just tried this rule, and it worked with GoDaddy hosting since they've already have the Microsoft URL Rewriting module installed for every IIS 7 account.

Use the async method in constructor???

constructor(props) {
    super(props);
    (async () => await this.qwe(() => console.log(props), () => console.log(props)))();
}

async qwe(q, w) {
    return new Promise((rs, rj) => {
        rs(q());
        rj(w());
    });
}

When a button is clicked with a mouse (and hopefully by touch), it records the X,Y coordinates. This is not the case when it is invoked by a form, these values are normally zero.

So you can do something like this.

function(e) {
  const isArtificial = e.screenX === 0 && e.screenY === 0
    && e.x === 0 && e.y === 0 
    && e.clientX === 0 && e.clientY === 0;

    if (isArtificial) {
      return; // DO NOTHING
    } else {
      // OPTIONAL: Don't submit the form when clicked 
      // e.preventDefault();
      // e.stopPropagation();
    }

    // ...Natural code goes here
}

If you don't mind using a bit of html, something like this should work.

from IPython.display import HTML, display

def display_table(data):
    html = "<table>"
    for row in data:
        html += "<tr>"
        for field in row:
            html += "<td><h4>%s</h4><td>"%(field)
        html += "</tr>"
    html += "</table>"
    display(HTML(html))

And then use it like this

data = [[1,2,3],[4,5,6],[7,8,9]]
display_table(data)

Not forgetting

.equalsIgnoreCase(String)

if you're not worried about that sort of thing...

Go to gradle.properties file (project root directory) and add these options.

Your proposed doCalculationsAndUpdateUIs does data processing and dispatches UI updates to the main queue. I presume that you have dispatched doCalculationsAndUpdateUIs to a background queue when you first called it.

While technically fine, that's a little fragile, contingent upon your remembering to dispatch it to the background every time you call it: I would, instead, suggest that you do your dispatch to the background and dispatch back to the main queue from within the same method, as it makes the logic unambiguous and more robust, etc.

Thus it might look like:

- (void)doCalculationsAndUpdateUIs {

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, NULL), ^{

        // DATA PROCESSING 1 

        dispatch_async(dispatch_get_main_queue(), ^{
            // UI UPDATION 1
        });

        /* I expect the control to come here after UI UPDATION 1 */

        // DATA PROCESSING 2

        dispatch_async(dispatch_get_main_queue(), ^{
            // UI UPDATION 2
        });

        /* I expect the control to come here after UI UPDATION 2 */

        // DATA PROCESSING 3

        dispatch_async(dispatch_get_main_queue(), ^{
            // UI UPDATION 3
        });
    });
}

In terms of whether you dispatch your UI updates asynchronously with dispatch_async (where the background process will not wait for the UI update) or synchronously with dispatch_sync (where it will wait for the UI update), the question is why would you want to do it synchronously: Do you really want to slow down the background process as it waits for the UI update, or would you like the background process to carry on while the UI update takes place.

Generally you would dispatch the UI update asynchronously with dispatch_async as you've used in your original question. Yes, there certainly are special circumstances where you need to dispatch code synchronously (e.g. you're synchronizing the updates to some class property by performing all updates to it on the main queue), but more often than not, you just dispatch the UI update asynchronously and carry on. Dispatching code synchronously can cause problems (e.g. deadlocks) if done sloppily, so my general counsel is that you should probably only dispatch UI updates synchronously if there is some compelling need to do so, otherwise you should design your solution so you can dispatch them asynchronously.

In answer to your question as to whether this is the "best way to achieve this", it's hard for us to say without knowing more about the business problem being solved. For example, if you might be calling this doCalculationsAndUpdateUIs multiple times, I might be inclined to use my own serial queue rather than a concurrent global queue, in order to ensure that these don't step over each other. Or if you might need the ability to cancel this doCalculationsAndUpdateUIs when the user dismisses the scene or calls the method again, then I might be inclined to use a operation queue which offers cancelation capabilities. It depends entirely upon what you're trying to achieve.

But, in general, the pattern of asynchronously dispatching a complicated task to a background queue and then asynchronously dispatching the UI update back to the main queue is very common.

in angular2 2.1.1 I was not able to catch the exception using the (data),(error) pattern, so I implemented it using .catch(...).

It's nice because it can be used with all other Observable chained methods like .retry .map etc.

import {Observable} from 'rxjs/Rx';


  Http
  .put(...)
  .catch(err =>  { 
     notify('UI error handling');
     return Observable.throw(err); // observable needs to be returned or exception raised
  })
  .subscribe(data => ...) // handle success

from documentation:

Returns

(Observable): An observable sequence containing elements from consecutive source sequences until a source sequence terminates successfully.

While you use .on(), it's basically a live query that you are using.

On the other hand, .ready (as in your case) is a static query. While using it, you can dynamically update data and do not have to wait for the page to load. You can simply pass on the values into your database (if required) when a particular value is entered.

The use of live queries is common in forms where we enter data (account or posts or even comments).

If you're running Angular 2 through ASP.NET Core 1 in Visual Studio 2015, you might find this solution from Jürgen Gutsch helpful. He describes it in a blog post. It was the best solution for me. Place the C# code provided below in your Startup.cs public void Configure() just before app.UseStaticFiles();

app.Use( async ( context, next ) => {
    await next();

    if( context.Response.StatusCode == 404 && !Path.HasExtension( context.Request.Path.Value ) ) {
        context.Request.Path = "/index.html";
        await next();
    }
});

In the previous answer also in the section <selector>...</selector> you may need:

<item android:state_pressed="true" android:drawable="@drawable/checkbox_pressed" ></item>

you can save the model in json and weights in a hdf5 file format.

# keras library import  for Saving and loading model and weights

from keras.models import model_from_json
from keras.models import load_model

# serialize model to JSON
#  the keras model which is trained is defined as 'model' in this example
model_json = model.to_json()


with open("model_num.json", "w") as json_file:
    json_file.write(model_json)

# serialize weights to HDF5
model.save_weights("model_num.h5")

files "model_num.h5" and "model_num.json" are created which contain our model and weights

To use the same trained model for further testing you can simply load the hdf5 file and use it for the prediction of different data. here's how to load the model from saved files.

# load json and create model
json_file = open('model_num.json', 'r')

loaded_model_json = json_file.read()
json_file.close()
loaded_model = model_from_json(loaded_model_json)

# load weights into new model
loaded_model.load_weights("model_num.h5")
print("Loaded model from disk")

loaded_model.save('model_num.hdf5')
loaded_model=load_model('model_num.hdf5')

To predict for different data you can use this

loaded_model.predict_classes("your_test_data here")

Remove the dot in front of your class so it looks like this:

<div class="col-xs-2 col-xs-offset-1">col</div>

A method is not (yet) a first-class object in Java; you can't pass a function pointer as a callback. Instead, create an object (which usually implements an interface) that contains the method you need and pass that.

Proposals for closures in Java—which would provide the behavior you are looking for—have been made, but none will be included in the upcoming Java 7 release.

You can have - characters in your images. Assume you have a local image (not a local registry) named centos-base-image with tag 7.3.1611.

In the example above FROM is fetching your local image, you can provide additional instructions to fetch an image from your custom registry (e.g. FROM localhost:5000/my-image:with.tag). See https://docs.docker.com/engine/reference/commandline/pull/#pull-from-a-different-registry and https://docs.docker.com/registry/#tldr

Finally, if your image is not being resolved when providing a name, try adding a tag to the image when you create it

This GitHub thread describes a similar issue of not finding local images by name.

By omitting a specific tag, docker will look for an image tagged "latest", so either create an image with the :latest tag, or change your FROM

I'm using json lib from http://json-lib.sourceforge.net/
json-lib-2.1-jdk15.jar

import net.sf.json.JSONObject;

{
    //put attributes
    Map m = New HashMap();
    m.put("send_to","[email protected]");
    m.put("email_subject","this is a test email");
    m.put("email_content","test email content");

    //generate JSON Object
    JSONObject json = JSONObject.fromObject(content);
    String message = json.toString();
    ...
}

public void receive(String jsonMessage)
{
    //parse attributes
    JSONObject json = JSONObject.fromObject(jsonMessage);
    String to = (String) json.get("send_to");

The API appears to have changed (or at least, it doesn't work for me).

Running the following in the Package Manager Console works as expected:

Update-Database -Script -SourceMigration:0

There is simple way to do it if you fear Javascript...I'm still learning. Open Street makes a simple Wordpress plugin you can customize. Add OSM Widget plugin.

This will be a filler until I figure out my Python Java concotion using coverter TIGER line files from the Census Bureau.

div { margin: auto; }

This will center your div.

Div by itself is a blockelement. Therefor you need to define the style to the div how to behave.

Use the ViewPager.onPageChangeListener:

viewPager.addOnPageChangeListener(new OnPageChangeListener() {
    public void onPageScrollStateChanged(int state) {}
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}

    public void onPageSelected(int position) {
        // Check if this is the page you want.
    }
});

I love the fact that ASP.NET Core's MVC6 merged the two patterns into one because I often need to support both worlds. While it's true that you can tweak any standard MVC Controller (and/or develop your own ActionResult classes) to act & behave just like an ApiController, it can be very hard to maintain and to test: on top of that, having Controllers methods returning ActionResult mixed with others returning raw/serialized/IHttpActionResult data can be very confusing from a developer perspective, expecially if you're not working alone and need to bring other developers to speed with that hybrid approach.

The best technique I've come so far to minimize that issue in ASP.NET non-Core web applications is to import (and properly configure) the Web API package into the MVC-based Web Application, so I can have the best of both worlds: Controllers for Views, ApiControllers for data.

In order to do that, you need to do the following:

• Install the following Web API packages using NuGet: Microsoft.AspNet.WebApi.Core and Microsoft.AspNet.WebApi.WebHost.
• Add one or more ApiControllers to your /Controllers/ folder.
• Add the following WebApiConfig.cs file to your /App_Config/ folder:

using System.Web.Http;

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

Finally, you'll need to register the above class to your Startup class (either Startup.cs or Global.asax.cs, depending if you're using OWIN Startup template or not).

Startup.cs

 public void Configuration(IAppBuilder app)
 {
    // Register Web API routing support before anything else
    GlobalConfiguration.Configure(WebApiConfig.Register);

    // The rest of your file goes there
    // ...
    AreaRegistration.RegisterAllAreas();
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

    ConfigureAuth(app);
    // ...
}

Global.asax.cs

protected void Application_Start()
{
    // Register Web API routing support before anything else
    GlobalConfiguration.Configure(WebApiConfig.Register);

    // The rest of your file goes there
    // ...
    AreaRegistration.RegisterAllAreas();
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
    // ...
}

This approach - together with its pros and cons - is further explained in this post I wrote on my blog.

If you want two objects with the same elements but in a different order to compare equal, then the obvious thing to do is compare sorted copies of them - for instance, for the dictionaries represented by your JSON strings a and b:

import json

a = json.loads("""
{
    "errors": [
        {"error": "invalid", "field": "email"},
        {"error": "required", "field": "name"}
    ],
    "success": false
}
""")

b = json.loads("""
{
    "success": false,
    "errors": [
        {"error": "required", "field": "name"},
        {"error": "invalid", "field": "email"}
    ]
}
""")

>>> sorted(a.items()) == sorted(b.items())
False

... but that doesn't work, because in each case, the "errors" item of the top-level dict is a list with the same elements in a different order, and sorted() doesn't try to sort anything except the "top" level of an iterable.

To fix that, we can define an ordered function which will recursively sort any lists it finds (and convert dictionaries to lists of (key, value) pairs so that they're orderable):

def ordered(obj):
    if isinstance(obj, dict):
        return sorted((k, ordered(v)) for k, v in obj.items())
    if isinstance(obj, list):
        return sorted(ordered(x) for x in obj)
    else:
        return obj

If we apply this function to a and b, the results compare equal:

>>> ordered(a) == ordered(b)
True

They are useful with Boost.Asio when you are not guaranteed that a target object still exists when an asynchronous handler is invoked. The trick is to bind a weak_ptr into the asynchonous handler object, using std::bind or lambda captures.

void MyClass::startTimer()
{
    std::weak_ptr<MyClass> weak = shared_from_this();
    timer_.async_wait( [weak](const boost::system::error_code& ec)
    {
        auto self = weak.lock();
        if (self)
        {
            self->handleTimeout();
        }
        else
        {
            std::cout << "Target object no longer exists!\n";
        }
    } );
}

This is a variant of the self = shared_from_this() idiom often seen in Boost.Asio examples, where a pending asynchronous handler will not prolong the lifetime of the target object, yet is still safe if the target object is deleted.

make sure you are not including the jquery code between the

< script > < /script >

If so remove that and code will work fine, It worked in my case.

You can use fall-through:

switch (pageid)
{
    case "listing-page":
    case "home-page":
        alert("hello");
        break;
    case "details-page":
        alert("goodbye");
        break;
}

As johnnyynnoj mentioned ng-repeat creates a new scope. I would in fact use a function to set the value. See plunker

JS:

$scope.setSelected = function(selected) {
  $scope.selected = selected;
}

You don't need to do an explicit typedef for classes and structs. What do you need the typedef for? Further, the typedef after a template<...> is syntactically wrong. Simply use:

template <class T>
struct array {
  size_t x;
  T *ary;
} ;

You can also add this to your form:

<form ... target="_blank">

It is now much easier to do this in Eclipse now. Just right click on the package that will contain your new activity. New -> Other -> (Under Android tab) Android Activity.

And that's all. Your new activity is automatically added to the manifest file as well.

Go up a level from the work directory

import os
os.path.dirname(os.getcwd())

or from the current directory

import os
os.path.dirname('current path')

Use a CASE statement
UPDATE: The previous syntax (as pointed out by a few people) doesn't work. You can use CASE as follows:

WHERE OrderNumber LIKE
  CASE WHEN IsNumeric(@OrderNumber) = 1 THEN 
    @OrderNumber 
  ELSE
    '%' + @OrderNumber
  END

Or you can use an IF statement like @N. J. Reed points out.

This is what solved my problem. ^M is a carriage return, and it can be easily avoided in a Perl script.

while(<INPUTFILE>)
{
     chomp;
     chop($_) if ($_ =~ m/\r$/);
}

Since the indexing in ArrayList starts from 0 and ends one place before the actual size hence the correct statement to return the last arraylist element would be:

int last = mylist.get(mylist.size()-1);

For example:

if size of array list is 5, then size-1 = 4 would return the last array element.

You may like to first create a dialogue by right clicking the project in solution explorer and in the code file type

dialogue1.show()

that's all !!!

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:

If you want to do something like the following example, you'd have to use nested ifs.

If percentage is greater than or equal to 93%, then corresponding value in B should be 4 and if the percentage is greater than or equal to 90% and less than 92%, then corresponding value in B to be 3.7, etc.

Here's how you'd do it:

=IF(A2>=93%, 4, IF(A2>=90%, 3.7,IF(A2>=87%,3.3,0)))

It's not "baked in to Swift", but you can use standard UIKit methods to do it. Take a look at UIApplication's openUrl(_:) (deprecated) and open(_:options:completionHandler:).

Swift 4 + Swift 5 (iOS 10 and above)

guard let url = URL(string: "https://stackoverflow.com") else { return }
UIApplication.shared.open(url)

Swift 3 (iOS 9 and below)

guard let url = URL(string: "https://stackoverflow.com") else { return }
UIApplication.shared.openURL(url)

Swift 2.2

guard let url = URL(string: "https://stackoverflow.com") else { return }
UIApplication.sharedApplication().openURL(url)    

You need to call $compile on the HTML string before inserting it into the DOM so that angular gets a chance to perform the binding.

In your fiddle, it would look something like this.

$("#dynamicContent").html(
  $compile(
    "<button ng-click='count = count + 1' ng-init='count=0'>Increment</button><span>count: {{count}} </span>"
  )(scope)
);

Obviously, $compile must be injected into your controller for this to work.

Read more in the $compile documentation.

I've used for my Wordpress blog this as .htaccess. It converts http://www.blah.example/asad, http://blah.example/asad, http://www.blah.example2/asad etc, to http://blah.example/asad Thanks to all other answers I figured this out.

Just write below code

$('.k-i-refresh').click();

Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

You have to hide the column at the grid view control rather than at the data source. Hiding it at the data source it will not render to the grid view at all, therefore you won't be able to access the value in the grid view. Doing it the way you're suggesting, you would have to access the column value through the data source as opposed to the grid view.

To hide the column on the grid view control, you can use code like this:

dataGridView1.Columns[0].Visible = false;

To access the column from the data source, you could try something like this:

object colValue = ((DataTable)dataGridView.DataSource).Rows[dataSetIndex]["ColumnName"];

This was also an easy way to add script and css in main.php

<script src="<?=Yii::app()->theme->baseUrl; ?>/js/bootstrap.min.js"></script>
<link href="<?=Yii::app()->theme->baseUrl; ?>/css/bootstrap.css" rel="stylesheet" type="text/css">

I haven't used it yet but I would take a look at http://www.zoneminder.com/ The documentation explains you can install it on a modest machine with linux and use IP cameras for remote recording.

Andrew

I would do this

var myDateStr= new Date("2015/5/2");

if( ! isNaN ( myDateStr.getMonth() )) {
    console.log("Valid date");
}
else {
    console.log("Invalid date");
}

"unhandled event loop exception .. no more handles" error (in my case) was caused by the driver of my mouse ! closing my mouse driver solved the problem. It has nothing to do with Eclipse versions, I tried almost all versions after Helios(in both 64bit/32bit) and all of them have the same problem, I also tried to add Eclipse/JRE variable path within advanced windows settings "environment variables". To help you to resolve this error try to close up unused applications and drivers.

It can be done by using ecapture First, run

pip install ecapture

Then in a new python script type:

    from ecapture import ecapture as ec

    ec.capture(0,"test","img.jpg")

More information from thislink

The Python manual has this to say about id():

Return the "identity'' of an object. This is an integer (or long integer) which is guaranteed to be unique and constant for this object during its lifetime. Two objects with non-overlapping lifetimes may have the same id() value. (Implementation note: this is the address of the object.)

So in CPython, this will be the address of the object. No such guarantee for any other Python interpreter, though.

Note that if you're writing a C extension, you have full access to the internals of the Python interpreter, including access to the addresses of objects directly.

Moreover, Please refer to load(Reader reader) method from Property class on javadoc

In load(Reader reader) method documentation it says

The key contains all of the characters in the line starting with the first non-white space character and up to, but not including, the first unescaped '=', ':', or white space character other than a line terminator. All of these key termination characters may be included in the key by escaping them with a preceding backslash character; for example,

\:\=

would be the two-character key ":=". Line terminator characters can be included using \r and \n escape sequences. Any white space after the key is skipped; if the first non-white space character after the key is '=' or ':', then it is ignored and any white space characters after it are also skipped. All remaining characters on the line become part of the associated element string; if there are no remaining characters, the element is the empty string "". Once the raw character sequences constituting the key and element are identified, escape processing is performed as described above.

Hope that helps.

string s = o as string; // 2

Is prefered, as it avoids the performance penalty of double casting.

If you want the super-hacky way to do it:

cat .git/`cat .git/HEAD | cut -d \  -f 2`

Basically, git stores the location of HEAD in .git/HEAD, in the form ref: {path from .git}. This command reads that out, slices off the "ref: ", and reads out whatever file it pointed to.

This, of course, will fail in detached-head mode, as HEAD won't be "ref:...", but the hash itself - but you know, I don't think you expect that much smarts in your bash one-liners. If you don't think semicolons are cheating, though...

HASH="ref: HEAD"; while [[ $HASH == ref\:* ]]; do HASH="$(cat ".git/$(echo $HASH | cut -d \  -f 2)")"; done; echo $HASH

If you are not into Cygwin, you can use native Windows builds. Some are here: curl Download Wizard.

Another alternative: use {} inside quotation marks to easily create dynamic names. This is similar to other solutions but not exactly the same, and I find it easier.

library(dplyr)
library(tibble)

iris <- as_tibble(iris)

multipetal <- function(df, n) {
  df <- mutate(df, "petal.{n}" := Petal.Width * n)  ## problem arises here
  df
}

for(i in 2:5) {
  iris <- multipetal(df=iris, n=i)
}
iris

I think this comes from dplyr 1.0.0 but not sure (I also have rlang 4.7.0 if it matters).

The selected answer dates from a while back. It is not practical to declare every binding in a custom HK2 binder. I'm using Tomcat and I just had to add one dependency. Even though it was designed for Glassfish it fits perfectly into other containers.

   <dependency>
        <groupId>org.glassfish.jersey.containers.glassfish</groupId>
        <artifactId>jersey-gf-cdi</artifactId>
        <version>${jersey.version}</version>
    </dependency>

Make sure your container is properly configured too (see the documentation).

The answer comes from the javadoc of ZoneId (emphasis mine) ...

A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:

• Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
• Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply

Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.

... and from the javadoc of ZoneId#of (emphasis mine):

This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.

The argument id is specified as "UTC", therefore it will return a ZoneId with an offset, which also presented in the string form:

System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));

Outputs:

2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]

As you use the equals method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false.

When the normalized() method is used as proposed in the documentation, the comparison using equals will return true, as normalized() will return the corresponding ZoneOffset:

Normalizes the time-zone ID, returning a ZoneOffset where possible.

now.withZoneSameInstant(ZoneOffset.UTC)
    .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true

As the documentation states, if you use "Z" or "+0" as input id, of will return the ZoneOffset directly and there is no need to call normalized():

now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true

To check if they store the same date time, you can use the isEqual method instead:

now.withZoneSameInstant(ZoneOffset.UTC)
    .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true

Sample

System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
        .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));

Output:

equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true

2014 March: Truncating long strings with CSS: a new answer with focus on browser support

Demo on http://jsbin.com/leyukama/1/ (I use jsbin because it supports old version of IE).

<style type="text/css">
    span {
        display: inline-block;
        white-space: nowrap;
        overflow: hidden;
        text-overflow: ellipsis;     /** IE6+, Firefox 7+, Opera 11+, Chrome, Safari **/
        -o-text-overflow: ellipsis;  /** Opera 9 & 10 **/
        width: 370px; /* note that this width will have to be smaller to see the effect */
    }
</style>

<span>Some very long text that should be cut off at some point coz it's a bit too long and the text overflow ellipsis feature is used</span>

The -ms-text-overflow CSS property is not necessary: it is a synonym of the text-overflow CSS property, but versions of IE from 6 to 11 already support the text-overflow CSS property.

Successfully tested (on Browserstack.com) on Windows OS, for web browsers:

• IE6 to IE11
• Opera 10.6, Opera 11.1, Opera 15.0, Opera 20.0
• Chrome 14, Chrome 20, Chrome 25
• Safari 4.0, Safari 5.0, Safari 5.1
• Firefox 7.0, Firefox 15

Firefox: as pointed out by Simon Lieschke (in another answer), Firefox only support the text-overflow CSS property from Firefox 7 onwards (released September 27th 2011).

I double checked this behavior on Firefox 3.0 & Firefox 6.0 (text-overflow is not supported).

Some further testing on a Mac OS web browsers would be needed.

Note: you may want to show a tooltip on mouse hover when an ellipsis is applied, this can be done via javascript, see this questions: HTML text-overflow ellipsis detection and HTML - how can I show tooltip ONLY when ellipsis is activated

Depending on your version:

Python 2.x:

for key, val in PIX0.iteritems():
    NUM = input("Which standard has a resolution of {!r}?".format(val))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but thats wrong. The correct answer was: {!r}.".format(key))

Python 3.x:

for key, val in PIX0.items():
    NUM = input("Which standard has a resolution of {!r}?".format(val))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but thats wrong. The correct answer was: {!r}.".format(key))

You should also get in the habit of using the new string formatting syntax ({} instead of % operator) from PEP 3101:

https://www.python.org/dev/peps/pep-3101/

I would inherit from ValueError

class IllegalArgumentError(ValueError):
    pass

It is sometimes better to create your own exceptions, but inherit from a built-in one, which is as close to what you want as possible.

If you need to catch that specific error, it is helpful to have a name.

The error you are receiving is due to how you define jet. You are creating the base class Colormap with the name 'jet', but this is very different from getting the default definition of the 'jet' colormap. This base class should never be created directly, and only the subclasses should be instantiated.

What you've found with your example is a buggy behavior in Matplotlib. There should be a clearer error message generated when this code is run.

This is an updated version of your example:

import matplotlib.pyplot as plt
import matplotlib.colors as colors
import matplotlib.cm as cmx
import numpy as np

# define some random data that emulates your indeded code:
NCURVES = 10
np.random.seed(101)
curves = [np.random.random(20) for i in range(NCURVES)]
values = range(NCURVES)

fig = plt.figure()
ax = fig.add_subplot(111)
# replace the next line 
#jet = colors.Colormap('jet')
# with
jet = cm = plt.get_cmap('jet') 
cNorm  = colors.Normalize(vmin=0, vmax=values[-1])
scalarMap = cmx.ScalarMappable(norm=cNorm, cmap=jet)
print scalarMap.get_clim()

lines = []
for idx in range(len(curves)):
    line = curves[idx]
    colorVal = scalarMap.to_rgba(values[idx])
    colorText = (
        'color: (%4.2f,%4.2f,%4.2f)'%(colorVal[0],colorVal[1],colorVal[2])
        )
    retLine, = ax.plot(line,
                       color=colorVal,
                       label=colorText)
    lines.append(retLine)
#added this to get the legend to work
handles,labels = ax.get_legend_handles_labels()
ax.legend(handles, labels, loc='upper right')
ax.grid()
plt.show()

Resulting in:

Using a ScalarMappable is an improvement over the approach presented in my related answer: creating over 20 unique legend colors using matplotlib

I think this is similar to kouton's answer, but this one just takes in a timeStamp and returns a timestamp SOMEWHERE in the next month. You could use date("m", $nextMonthDateN) from there.

function nextMonthTimeStamp($curDateN){ 
   $nextMonthDateN = $curDateN;
   while( date("m", $nextMonthDateN) == date("m", $curDateN) ){
      $nextMonthDateN += 60*60*24*27;
   }
   return $nextMonthDateN; //or return date("m", $nextMonthDateN);
}

As of Laravel 5.2+, you can fetch it directly with $request->input('item') as well.

Retrieving JSON Input Values

When sending JSON requests to your application, you may access the JSON data via the input method as long as the Content-Type header of the request is properly set to application/json. You may even use "dot" syntax to dig deeper into JSON arrays:

$name = $request->input('user.name');

https://laravel.com/docs/5.2/requests

As noted above, the content-type header must be set to application/json so the jQuery ajax call would need to include contentType: "application/json",

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    dataType: "json",
    contentType: "application/json",
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

By fixing the AJAX call, $request->all() should work.

you can take care of the first 3 items with slicing and head:

1. df[df.A>=4].head(1)
2. df[(df.A>=4)&(df.B>=3)].head(1)
3. df[(df.A>=4)&((df.B>=3) * (df.C>=2))].head(1)

The condition in case nothing comes back you can handle with a try or an if...

try:
    output = df[df.A>=6].head(1)
    assert len(output) == 1
except: 
    output = df.sort_values('A',ascending=False).head(1)

I had some data I had to get from mssql into mysql, had difficulty finding a solution. So what I did in the end (a bit of a long winded way to do it, but as a last resort it works) was:

• Open the mssql database in sql server management studio express (I used 2005)
• Open each table in turn and

• Click the top left corner box to select whole table:

• Copy data to clipboard (ctrl + v)

• Open ms excel
• Paste data from clipboard
• Save excel file as .csv
• Repeat the above for each table
• You should now be able to import the data into mysql

Hope this helps

        return false;
    }

    // Check that the remote file was found. The ContentType
    // check is performed since a request for a non-existent
    // image file might be redirected to a 404-page, which would
    // yield the StatusCode "OK", even though the image was not
    // found.
    if ((response.StatusCode == HttpStatusCode.OK ||
        response.StatusCode == HttpStatusCode.Moved ||
        response.StatusCode == HttpStatusCode.Redirect) &&
        response.ContentType.StartsWith("image", StringComparison.OrdinalIgnoreCase))
    {

        // if the remote file was found, download it
        using (Stream inputStream = response.GetResponseStream())
        using (Stream outputStream = File.OpenWrite(fileName))
        {
            byte[] buffer = new byte[4096];
            int bytesRead;
            do
            {
                bytesRead = inputStream.Read(buffer, 0, buffer.Length);
                outputStream.Write(buffer, 0, bytesRead);
            } while (bytesRead != 0);
        }
        return true;
    }
    else
        return false;
}

Main changes are:

• using a try/catch for the GetResponse() as I was running into an exception when the remote file returned 404
• returning a boolean

A simple answer to this question can be:

1. Read A Number "n" From The User.
2. Using While Loop Make Sure Its Not Zero.
3. Take modulus 10 Of The Number "n"..This Will Give You Its Last Digit.
4. Then Divide The Number "n" By 10..This Removes The Last Digit of Number "n" since in int decimal part is omitted.
5. Display Out The Number.

I Think It Will Help. I Used Simple Code Like:

#include <iostream>
using namespace std;
int main()
{int n,r;

    cout<<"Enter Your Number:";
    cin>>n;


    while(n!=0)
    {
               r=n%10;
               n=n/10;

               cout<<r;
    }
    cout<<endl;

    system("PAUSE");
    return 0;
}

git remote add origin <remote_repo_url>
git push --all origin

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

        $services = $this->Service->find('all', array(
            'limit' =>4,
            'fields' => array('Service.*','ServiceImage.*'),
            'joins' => array(
                array(
                        'table' => 'services_images',
                        'alias' => 'ServiceImage',
                        'type' => 'INNER',
                        'conditions' => array(
                        'ServiceImage.service_id' =>'Service.id'
                        )
                    ),
                ),
            )
        );

It goges to array is null.

You can say that it is with PHP, but actually it has just one PHP command, all other files are just *.html.

1. You should have a file named .htaccess in your web server's /public_html directory, or in another directory, where your html file will be and you will process one command inside it.
2. If you do not have it, (or it might be hidden (you should check this directory list by checking directory for hidden files)), you can create it with notepad, and just type one row in it:
   AddType application/x-httpd-php .html
3. Save this file with the name .htaccess and upload it to the server's main directory.
4. In your html file anywhere you want an external "meniu.html file to appear, add te command: <?php include("meniu.html"); ?>.

That's all!

Remark: all commands like <? ...> will be treated as php executables, so if your html have question marks, then you could have some problems.

Adding only android-support-v7-appcompat.jar to library dependencies is not enough, you have also to import in your project the module that you can find in your SDK at the path \android-sdk\extras\android\support\v7\appcompatand after that add module dependencies configuring the project structure in this way

otherwise are included only the class files of support library and the app is not able to load the other resources causing the error.

In addition as reVerse suggested replace this

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout,new Toolbar(MyActivity.this) ,
                    R.string.ns_menu_open, R.string.ns_menu_close);
        }

with

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
        }

A two value assignment can be used for this purpose. Please check my sample program below

package main

import (
    "fmt"
)

func main() {
    //creating a map with 3 key-value pairs
    sampleMap := map[string]int{"key1": 100, "key2": 500, "key3": 999}
    //A two value assignment can be used to check existence of a key.
    value, isKeyPresent := sampleMap["key2"]
    //isKeyPresent will be true if key present in sampleMap
    if isKeyPresent {
        //key exist
        fmt.Println("key present, value =  ", value)
    } else {
        //key does not exist
        fmt.Println("key does not exist")
    }
}

Not sure if this works in all os, try it out.

ifconfig | awk -F"[ :]+" '/inet addr/ && !/127.0/ {print $4}'

Simplest way IMO is to include an ID and runat server tag on all your elements.

<div id="MYDIV" runat="server" />

Since it sounds like these are dynamically inserted controls, you might appreciate FindControl().

This simple program helps you in understanding how to feed the user input from command line and to show help on passing invalid argument.

import argparse
import sys

try:
     parser = argparse.ArgumentParser()
     parser.add_argument("square", help="display a square of a given number",
                type=int)
    args = parser.parse_args()

    #print the square of user input from cmd line.
    print args.square**2

    #print all the sys argument passed from cmd line including the program name.
    print sys.argv

    #print the second argument passed from cmd line; Note it starts from ZERO
    print sys.argv[1]
except:
    e = sys.exc_info()[0]
    print e

1) To find the square root of 5

C:\Users\Desktop>python -i emp.py 5
25
['emp.py', '5']
5

2) Passing invalid argument other than number

C:\Users\bgh37516\Desktop>python -i emp.py five
usage: emp.py [-h] square
emp.py: error: argument square: invalid int value: 'five'
<type 'exceptions.SystemExit'>

The LogManager class determines which log4j config to use in a static block which runs when the class is loaded. There are three options intended for end-users:

1. If you specify log4j.defaultInitOverride to false, it will not configure log4j at all.

2. Specify the path to the configuration file manually yourself and override the classpath search. You can specify the location of the configuration file directly by using the following argument to java:

   -Dlog4j.configuration=<path to properties file>

   in your test runner configuration.

3. Allow log4j to scan the classpath for a log4j config file during your test. (the default)

See also the online documentation.

This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:

var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";

$.ajax({
    type: "POST",
    url: "Default.aspx/OnSubmit",
    data: dataValue,
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
    },
    success: function (result) {
        alert("We returned: " + result.d);
    }
});

You can get the results with a simple:

@app.route('your route', methods=['GET'])
def yourMethod(params):
    response = flask.jsonify({'some': 'data'})
    response.headers.add('Access-Control-Allow-Origin', '*')
    return response

Way to unlock the user :

$ sqlplus  /nolog
SQL > conn sys as sysdba
SQL > ALTER USER USER_NAME ACCOUNT UNLOCK;

and open new terminal

SQL > sqlplus / as sysdba
connected
SQL > conn username/password  //which username u gave before unlock

• it will ask new password:password
• it will ask re-type password:password
• press enter u will get loggedin

You use std::find from <algorithm>, which works equally well for std::list and std::vector. std::vector does not have its own search/find function.

#include <list>
#include <algorithm>

int main()
{
    std::list<int> ilist;
    ilist.push_back(1);
    ilist.push_back(2);
    ilist.push_back(3);

    std::list<int>::iterator findIter = std::find(ilist.begin(), ilist.end(), 1);
}

Note that this works for built-in types like int as well as standard library types like std::string by default because they have operator== provided for them. If you are using using std::find on a container of a user-defined type, you should overload operator== to allow std::find to work properly: EqualityComparable concept

 //if you want to get parameter from url use:
 parse_str($_SERVER['QUERY_STRING'], $_GET);
 //then you can use:
 if(isset($_GET["par"])){
      echo $_GET["par"];
 }
 //if you want to get current page url use:
 $current_url = current_url();

Don't work with MAC addresses MAC addresses are globally unique, not user-resettable, and survive factory resets. For these reasons, it's generally not recommended to use MAC address for any form of user identification. Devices running Android 10 (API level 29) and higher report randomized MAC addresses to all apps that aren't device owner apps.

Between Android 6.0 (API level 23) and Android 9 (API level 28), local device MAC addresses, such as Wi-Fi and Bluetooth, aren't available via third-party APIs. The WifiInfo.getMacAddress() method and the BluetoothAdapter.getDefaultAdapter().getAddress() method both return 02:00:00:00:00:00.

Additionally, between Android 6.0 and Android 9, you must hold the following permissions to access MAC addresses of nearby external devices available via Bluetooth and Wi-Fi scans:

Method/Property Permissions Required

ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION

You could do this:

public static Boolean IsEmpty<T>(this IEnumerable<T> source)
{
    if (source == null)
        return true; // or throw an exception
    return !source.Any();
}

Edit: Note that simply using the .Count method will be fast if the underlying source actually has a fast Count property. A valid optimization above would be to detect a few base types and simply use the .Count property of those, instead of the .Any() approach, but then fall back to .Any() if no guarantee can be made.

Recent protocols prefer usage of RFC3339 per golang time package documentation.

In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs.

cutOffTime, _ := time.Parse(time.RFC3339, "2017-08-30T13:35:00Z")
// POSTDATE is a date time field in DB (datastore)
query := datastore.NewQuery("db").Filter("POSTDATE >=", cutOffTime).

KeyPress, KeyUp and KeyDown are analogous to, respectively: Click, MouseUp, and MouseDown.

1. Down happens first
2. Press happens second (when text is entered)
3. Up happens last (when text input is complete).

The exception is webkit, which has an extra event in there:

keydown
keypress
textInput     
keyup

Below is a snippet you can use to see for yourself when the events get fired:

window.addEventListener("keyup", log);
window.addEventListener("keypress", log);
window.addEventListener("keydown", log);

function log(event){
  console.log( event.type );
}

According to new Gradle based build system. We have to put assets under main folder.

Or simply right click on your project and create it like

File > New > folder > assets Folder

Go to data directory and try this:

mv database1 database2 

It works for me on a 900 MB database size.

You have several choices. The one that makes the most sense really depends on what you're trying to do.

Choice 1: make toyNumber a public member variable in a class

class MyToy {
  public int toyNumber;
}

then pass a reference to a MyToy to your method.

void play(MyToy toy){  
    System.out.println("Toy number in play " + toy.toyNumber);   
    toy.toyNumber++;  
    System.out.println("Toy number in play after increement " + toy.toyNumber);   
}

Choice 2: return the value instead of pass by reference

int play(int toyNumber){  
    System.out.println("Toy number in play " + toyNumber);   
    toyNumber++;  
    System.out.println("Toy number in play after increement " + toyNumber);   
    return toyNumber
}

This choice would require a small change to the callsite in main so that it reads, toyNumber = temp.play(toyNumber);.

Choice 3: make it a class or static variable

If the two functions are methods on the same class or class instance, you could convert toyNumber into a class member variable.

Choice 4: Create a single element array of type int and pass that

This is considered a hack, but is sometimes employed to return values from inline class invocations.

void play(int [] toyNumber){  
    System.out.println("Toy number in play " + toyNumber[0]);   
    toyNumber[0]++;  
    System.out.println("Toy number in play after increement " + toyNumber[0]);   
}

Add -fPIC at the end of CMAKE_CXX_FLAGS and CMAKE_C_FLAG

Example:

set( CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} -Wall --std=c++11 -O3 -fPIC" )
set( CMAKE_C_FLAGS  "${CMAKE_C_FLAGS} -Wall -O3 -fPIC" )

This solved my issue.

Use the TimeSpan object to capture your initial time element and use the methods such as AddHours or AddMinutes. To substract 3 hours, you will do AddHours(-3). To substract 45 mins, you will do AddMinutes(-45)

I've discovered that you can use eval to avoid using a subshell. Thus:

IFS=$'\n' eval 'echo "${my_array[*]}"'

I ran into a very obscure and annoying cause of error 6. After goofing around with some NFS mounted volumes, uploads started failing. Problem resolved by restarting services

systemctl restart php-fpm.service
systemctl restart httpd.service

Modified @Surendra Jnawali' code. It fails

if current time is 23:40:00 i.e greater than start time and less than equals to 23:59:59.

I'm very late to the party but this answer pulls up top in Google search results.

Bootstrap 3 has an answer for this built in, set your container div in your navbar to container-fluid and it'll fall to screen width.

Like so:

<div class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="container-fluid">
    <div class="navbar-collapse collapse">
      <ul class="nav navbar-nav">
        <li><a href="/">More Stuff</a></li>
      </ul>
    </div>
  </div>
</div>

You have to follow the following sequence of opeartions:

• Convert Map to MapSet with map.entrySet();
• Get the iterator with Mapset.iterator();
• Get Map.Entry with iterator.next();
• use Entry.getKey() and Entry.getValue()

# define Map
for (Map.Entry entry: map.entrySet)
    System.out.println(entry.getKey() + entry.getValue);

My preference is:

console.debug("jQuery "+ (jQuery ? $().jquery : "NOT") +" loaded")

Result:

jQuery 1.8.0 loaded

For PowerShell 3.0 users - following works for both modules and script files:

function Get-ScriptDirectory {
    Split-Path -parent $PSCommandPath
}

The above snippets don't work for cases with more than 1 day (They are simply ignored).

For this you can use:

function convertMS(ms) {
    var d, h, m, s;
    s = Math.floor(ms / 1000);
    m = Math.floor(s / 60);
    s = s % 60;
    h = Math.floor(m / 60);
    m = m % 60;
    d = Math.floor(h / 24);
    h = h % 24;
    h += d * 24;
    return h + ':' + m + ':' + s;
}

The question is what you really want to achieve when you asking for a workflow engine.

The general goal which you would like to achieve by using a workflow engine, is to become more flexible in changing your business logic during runtime. The modelling part is surely one of the most important here. BPMN 2.0 is a de-facto standard in this area and all of the discussed engines support this standard.

The second goal is to control the business process in the way of describing the 'what should happen when...' questions. And this part has a lot to do with the business requirements you are confronted within your project.

Some of the workflow engines (Activity, JBPM) can help you to answer this requirement by 'coding' your processes. This means that you model the 'what should happen when..' paradigm in a way, where you decide which part of your code (e.g a task or an event) should be executed by the workflow engine in various situations. A lot of discussion is going about this concept. And developers naturally ask whether this may not even be implemented by themselves. (It is in fact not so easy as it seems at the first glance)

Some other workflow engines (Imixs-Workflow, Bonita) can help you to answer the 'what should happen when...' requirement in a more user-centric way. This is the area of Human-centric business process management, which supports human skills and activities by a task orientated workflow-engine. The focus is more on the distribution of tasks and processes inside an organisation. The workflow engine helps you to distribute a task to a certain user or user group and to secure, log and monitor a long running business process. Maybe these are the things you do not really want to implement by yourself.

So my advice is, not to mix things that need to be considered separately, because workflow covers a very wide area.

You could maybe create a component that determines the offset between System.nanoTime() and System.currentTimeMillis() and effectively get nanoseconds since epoch.

public class TimerImpl implements Timer {

    private final long offset;

    private static long calculateOffset() {
        final long nano = System.nanoTime();
        final long nanoFromMilli = System.currentTimeMillis() * 1_000_000;
        return nanoFromMilli - nano;
    }

    public TimerImpl() {
        final int count = 500;
        BigDecimal offsetSum = BigDecimal.ZERO;
        for (int i = 0; i < count; i++) {
            offsetSum = offsetSum.add(BigDecimal.valueOf(calculateOffset()));
        }
        offset = (offsetSum.divide(BigDecimal.valueOf(count))).longValue();
    }

    public long nowNano() {
        return offset + System.nanoTime();
    }

    public long nowMicro() {
        return (offset + System.nanoTime()) / 1000;
    }

    public long nowMilli() {
        return System.currentTimeMillis();
    }
}

Following test produces fairly good results on my machine.

    final Timer timer = new TimerImpl();
    while (true) {
        System.out.println(timer.nowNano());
        System.out.println(timer.nowMilli());
    }

The difference seems to oscillate in range of +-3ms. I guess one could tweak the offset calculation a bit more.

I can' t comment yet but, just a hint: use try/catch clauses to avoid breaking the pipeline (if you are sure the file exists, disregard)

    pipeline {
        agent any
            stages {
                stage("foo") {
                    steps {
                        script {
                            try {                    
                                env.FILENAME = readFile 'output.txt'
                                echo "${env.FILENAME}"
                            }
                            catch(Exception e) {
                                //do something, e.g. echo 'File not found'
                            }
                        }
                   }
    }

Another hint (this was commented by @hao, and think is worth to share): you may want to trim like this readFile('output.txt').trim()

There's an entire practice that says it's a bad idea to have inline functions/styles. Taking into account you already have an ID for your button, consider

JS

var myvar=15;
function init(){
    document.getElementById('EditBanner').onclick=function(){EditBanner(myvar);};
}
window.onload=init;

HTML

<input id="EditBanner" type="button"  value="Edit Image" />

DELETE FROM tablename a
      WHERE a.ROWID > ANY (SELECT b.ROWID
                             FROM tablename b
                            WHERE a.fieldname = b.fieldname
                              AND a.fieldname2 = b.fieldname2)

Your code seems correct. I would presume it is something to do with the fact you are using a .png and the way the browser redraws the object upon rotation is inefficient, causing the hang (what browser are you testing under?)

If possible replace the .png with something native.

Chrome gives me no pauses using this method.

In my case Drag & Drop didn't work.

1. I had to first Sync iTunes with the iOS device (Sync button on the bottom right)
2. I had to add the IPA file through iTunes menu bar: File -> Add to Library...
3. I had to press the "Install" button for my app in the "Apps" screen
4. I had to press the "Apply" button on the bottom right

Both System.Timers.Timer and System.Threading.Timer will work for services.

The timers you want to avoid are System.Web.UI.Timer and System.Windows.Forms.Timer, which are respectively for ASP applications and WinForms. Using those will cause the service to load an additional assembly which is not really needed for the type of application you are building.

Use System.Timers.Timer like the following example (also, make sure that you use a class level variable to prevent garbage collection, as stated in Tim Robinson's answer):

using System;
using System.Timers;

public class Timer1
{
    private static System.Timers.Timer aTimer;

    public static void Main()
    {
        // Normally, the timer is declared at the class level,
        // so that it stays in scope as long as it is needed.
        // If the timer is declared in a long-running method,  
        // KeepAlive must be used to prevent the JIT compiler 
        // from allowing aggressive garbage collection to occur 
        // before the method ends. (See end of method.)
        //System.Timers.Timer aTimer;

        // Create a timer with a ten second interval.
        aTimer = new System.Timers.Timer(10000);

        // Hook up the Elapsed event for the timer.
        aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);

        // Set the Interval to 2 seconds (2000 milliseconds).
        aTimer.Interval = 2000;
        aTimer.Enabled = true;

        Console.WriteLine("Press the Enter key to exit the program.");
        Console.ReadLine();

        // If the timer is declared in a long-running method, use
        // KeepAlive to prevent garbage collection from occurring
        // before the method ends.
        //GC.KeepAlive(aTimer);
    }

    // Specify what you want to happen when the Elapsed event is 
    // raised.
    private static void OnTimedEvent(object source, ElapsedEventArgs e)
    {
        Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime);
    }
}

/* This code example produces output similar to the following:

Press the Enter key to exit the program.
The Elapsed event was raised at 5/20/2007 8:42:27 PM
The Elapsed event was raised at 5/20/2007 8:42:29 PM
The Elapsed event was raised at 5/20/2007 8:42:31 PM
...
 */

If you choose System.Threading.Timer, you can use as follows:

using System;
using System.Threading;

class TimerExample
{
    static void Main()
    {
        AutoResetEvent autoEvent     = new AutoResetEvent(false);
        StatusChecker  statusChecker = new StatusChecker(10);

        // Create the delegate that invokes methods for the timer.
        TimerCallback timerDelegate = 
            new TimerCallback(statusChecker.CheckStatus);

        // Create a timer that signals the delegate to invoke 
        // CheckStatus after one second, and every 1/4 second 
        // thereafter.
        Console.WriteLine("{0} Creating timer.\n", 
            DateTime.Now.ToString("h:mm:ss.fff"));
        Timer stateTimer = 
                new Timer(timerDelegate, autoEvent, 1000, 250);

        // When autoEvent signals, change the period to every 
        // 1/2 second.
        autoEvent.WaitOne(5000, false);
        stateTimer.Change(0, 500);
        Console.WriteLine("\nChanging period.\n");

        // When autoEvent signals the second time, dispose of 
        // the timer.
        autoEvent.WaitOne(5000, false);
        stateTimer.Dispose();
        Console.WriteLine("\nDestroying timer.");
    }
}

class StatusChecker
{
    int invokeCount, maxCount;

    public StatusChecker(int count)
    {
        invokeCount  = 0;
        maxCount = count;
    }

    // This method is called by the timer delegate.
    public void CheckStatus(Object stateInfo)
    {
        AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
        Console.WriteLine("{0} Checking status {1,2}.", 
            DateTime.Now.ToString("h:mm:ss.fff"), 
            (++invokeCount).ToString());

        if(invokeCount == maxCount)
        {
            // Reset the counter and signal Main.
            invokeCount  = 0;
            autoEvent.Set();
        }
    }
}

Both examples comes from the MSDN pages.

If one of the inserts fail, or any part of the command fails, does SQL server roll back the transaction?

No, it does not.

If it does not rollback, do I have to send a second command to roll it back?

Sure, you should issue ROLLBACK instead of COMMIT.

If you want to decide whether to commit or rollback the transaction, you should remove the COMMIT sentence out of the statement, check the results of the inserts and then issue either COMMIT or ROLLBACK depending on the results of the check.

While the answer given by Paul H shows the essential part, it is not a complete example. On the other hand the matplotlib example seems rather complicated and does not show how to use days.

So for everyone in need here is a full working example:

from datetime import datetime
import matplotlib.pyplot as plt
from matplotlib.dates import DateFormatter

myDates = [datetime(2012,1,i+3) for i in range(10)]
myValues = [5,6,4,3,7,8,1,2,5,4]
fig, ax = plt.subplots()
ax.plot(myDates,myValues)

myFmt = DateFormatter("%d")
ax.xaxis.set_major_formatter(myFmt)

## Rotate date labels automatically
fig.autofmt_xdate()
plt.show()

I was getting the same message message within dotNet Core 2.2 using MVC 5, however nothing was being logged to the Windows Event Viewer.

I found that I had changed the Project sdk from Microsoft.NET.Sdk.Web to Microsoft.NET.Sdk.Razor (seen within the projects.csproj file). I changed this back and it worked fine :)

Starting from the data.table y, you can just write:
y[, (cols):=lapply(.SD, function(i){i[is.na(i)] <- 0; i}), .SDcols = cols]
Don't forget to library(data.table) before creating y and running this command.

I had this happen after updating gcc and eclipse on ArchLinux. What solved it for me was Project -> C/C++ Index -> Rebuild.

Since x!=x returns the same boolean array with np.isnan(x) (because np.nan!=np.nan would return True), you could also write:

np.argwhere(x!=x)

However, I still recommend writing np.argwhere(np.isnan(x)) since it is more readable. I just try to provide another way to write the code in this answer.

The "wipe user data" option finally solved my problem. just wipe user data every time you start the emulator. This always works for me! I use windows 8 x64 , eclipse

I use this code:

<?php

{
//foreach (glob("images/*.jpg") as $large) 
foreach (glob("*.xml") as $filename) { 

//echo "$filename\n";
//echo str_replace("","","$filename\n");

echo str_replace("","","<a href='$filename'>$filename</a>\n");

}
}


?>

Unfortunately there is only the function setColumnWidth(int columnIndex, int width) from class Sheet; in which width is a number of characters in the standard font (first font in the workbook) if your fonts are changing you cannot use it. There is explained how to calculate the width in function of a font size. The formula is:

width = Truncate([{NumOfVisibleChar} * {MaxDigitWidth} + {5PixelPadding}] / {MaxDigitWidth}*256) / 256

You can always use autoSizeColumn(int column, boolean useMergedCells) after inputting the data in your Sheet.

To add to the above correct answer :- For my case in shell, this code worked (working on sqoop)

ROOT_PATH="path/to/the/folder"
--options-file  $ROOT_PATH/query.txt

Here's a variation on ashirazi's answer which doesn't rely on $IFS. It does have its own issues which I ouline below.

sentence="one;two;three"
sentence=${sentence//;/$'\n'}  # change the semicolons to white space
for word in $sentence
do
    echo "$word"
done

Here I've used a newline, but you could use a tab "\t" or a space. However, if any of those characters are in the text it will be split there, too. That's the advantage of $IFS - it can not only enable a separator, but disable the default ones. Just make sure you save its value before you change it - as others have suggested.

For rails 4.1.4 you can start server:

$ bin/rails server

Also to shed some light, it is important to know that var-arg parameters are limited to one and you can't have several var-art params. For example this is illigal:

public void myMethod(String... strings, int ... ints){
// method body
}

var script = (<HTMLScriptElement[]><any>document.getElementsByName(id))[0];    

Try this sqlite table schema parser, I implemented the sqlite table parser for parsing the table definitions in PHP.

It returns the full definitions (unique, primary key, type, precision, not null, references, table constraints... etc)

=== and !== are strict comparison operators:

JavaScript has both strict and type-converting equality comparison. For strict equality the objects being compared must have the same type and:

• Two strings are strictly equal when they have the same sequence of characters, same length, and same characters in corresponding positions.
• Two numbers are strictly equal when they are numerically equal (have the same number value). NaN is not equal to anything, including NaN. Positive and negative zeros are equal to one another.
• Two Boolean operands are strictly equal if both are true or both are false.
• Two objects are strictly equal if they refer to the same Object.
• Null and Undefined types are == (but not ===). [I.e. (Null==Undefined) is true but (Null===Undefined) is false]

Comparison Operators - MDC

Assuming that "a" and "b" are bean properties

rendered="#{bean.a==12 and (bean.b==13 or bean.b==15)}"

You may look at JSF EL operators

From the article you linked to:

The type can be one of the following values:

BINARY[(N)]

CHAR[(N)]

DATE

DATETIME

DECIMAL[(M[,D])]

SIGNED [INTEGER]

TIME

UNSIGNED [INTEGER]

Try SIGNED instead of INT

This works quite well in my local.py, saves me messing up the regular logging:

from .settings import *

LOGGING['handlers']['console'] = {
    'level': 'DEBUG',
    'class': 'logging.StreamHandler',
    'formatter': 'verbose'
}
LOGGING['loggers']['foo.bar'] = {
    'handlers': ['console'],
    'propagate': False,
    'level': 'DEBUG',
}

Just for others (like me) who might have faced the above error. The solution in simple terms.

You might have missed to register your Interface and class (which implements that inteface) registration in your code.

e.g if the error is
"The current type, xyznamespace. Imyinterfacename, is an interface and cannot be constructed. Are you missing a type mapping?"

Then you must register the class which implements the Imyinterfacename in the UnityConfig class in the Register method. using code like below

 container.RegisterType<Imyinterfacename, myinterfaceimplclassname>();

These code lines can help you quickly enable log setting in your magento site.

INSERT INTO `core_config_data` (`config_id`, `scope`, `scope_id`, `path`, `value`) VALUES
('', 'default', 0, 'dev/log/active', '1'),
('', 'default', 0, 'dev/log/file', 'system.log'),
('', 'default', 0, 'dev/log/exception_file', 'exception.log');

Then you can see them inside the folder: /var/log under root installation.

More detail in this blog

while True:
    b1=input('Type a number:')
    try:
        a1=int(b1)
    except ValueError:
        print ('"%(a1)s" is not a number. Try again.' %{'a1':b1})       
    else:
        print ('You typed "{}".'.format(a1))
        break

This makes a loop to check whether input is an integer or not, result would look like below:

>>> %Run 1.1.py
Type a number:d
"d" is not a number. Try again.
Type a number:
>>> %Run 1.1.py
Type a number:4
You typed 4.
>>> 

In your code if you use requestWindowFeature(Window.FEATURE_NO_TITLE); be sure that it goes before dialog.setContentView(); otherwise it causes the application to crash.

df.shape, where df is your DataFrame.

One case where *args and **kwargs are useful is when writing wrapper functions (such as decorators) that need to be able accept arbitrary arguments to pass through to the function being wrapped. For example, a simple decorator that prints the arguments and return value of the function being wrapped:

def mydecorator( f ):
   @functools.wraps( f )
   def wrapper( *args, **kwargs ):
      print "Calling f", args, kwargs
      v = f( *args, **kwargs )
      print "f returned", v
      return v
   return wrapper

I'm a complete noob on Entity but this is how I would do it in theory...

var name = yourDbContext.MyTable.Find(1).Name;

If It's A Primary Key.

-- OR --

var name = yourDbContext.MyTable.SingleOrDefault(mytable => mytable.UserId == 1).Name;

-- OR --

For whole Column:

var names = yourDbContext.MyTable
.Where(mytable => mytable.UserId == 1)
.Select(column => column.Name); //You can '.ToList();' this....

But "oh Geez Rick, What do I know..."

For anyone trying to display cronjobs in a crontab and getting frustrated on how to separate each line, use explode:

$output = shell_exec('crontab -l');
$cron_array = explode(chr(10),$output);

using '\n' doesnt seem to work but chr(10) works nicely :D

hope this saves some one some headaches.

let content = "<center><h1>404 Not Found</h1></center>"
let result = $("<div/>").html(content).text()

content: <center><h1>404 Not Found</h1></center>,
result: "404 Not Found"

Absolute positioning positions an element relative to its nearest positioned ancestor. So put position: relative on the container, then for child elements, top and left will be relative to the top-left of the container so long as the child elements have position: absolute. More information is available in the CSS 2.1 specification.

Here is what I ended up doing to work around the error.

First, I set up the database recovery model as SIMPLE. More information here.

Then, by deleting some old files I was able to make 5GB of free space which gave the log file more space to grow.

I reran the DELETE statement sucessfully without any warning.

I thought that by running the DELETE statement the database would inmediately become smaller thus freeing space in my hard drive. But that was not true. The space freed after a DELETE statement is not returned to the operating system inmediatedly unless you run the following command:

DBCC SHRINKDATABASE (MyDb, 0);
GO

More information about that command here.

Sadly, no.

I agree that such frequent operation should have easier implementation than copying of input line by line in loop, but you'll have to either write helper method or use external library.

Select into for large datasets may be good only for a single user using one single connection to the database doing a bulk operation task. I do not recommend to use

SELECT * INTO table

as this creates one big transaction and creates schema lock to create the object, preventing other users to create object or access system objects until the SELECT INTO operation completes.

As proof of concept open 2 sessions, in first session try to use

select into temp table from a huge table 

and in the second section try to

create a temp table 

and check the locks, blocking and the duration of second session to create a temp table object. My recommendation it is always a good practice to create and Insert statement and if needed for minimal logging use trace flag 610.

I think the best option is:

1. Create a model class as config schema

2. Register in DI: services.Configure(Configuration.GetSection("democonfig"));

3. Get the values as model object from DI in your controller:

   private readonly your_model myConfig;
   public DemoController(IOptions<your_model> configOps)
   {
       this.myConfig = configOps.Value;
   }
   

You'll need to either insert BR tag appropriately in the resulting string, or use for example a PRE tag so that the formatting of the stringify is retained:

var data = { a: 1, b: 2 };

var Hello = React.createClass({
    render: function() {
        return <div><pre>{JSON.stringify(data, null, 2) }</pre></div>;
    }
});

React.render(<Hello />, document.getElementById('container'));

Working example.

Update

class PrettyPrintJson extends React.Component {
    render() {
         // data could be a prop for example
         // const { data } = this.props;
         return (<div><pre>{JSON.stringify(data, null, 2) }</pre></div>);
    }
}

ReactDOM.render(<PrettyPrintJson/>, document.getElementById('container'));

Stateless Functional component, React .14 or higher

const PrettyPrintJson = ({data}) => {
    // (destructured) data could be a prop for example
    return (<div><pre>{ JSON.stringify(data, null, 2) }</pre></div>);
}

Or, ...

const PrettyPrintJson = ({data}) => (<div><pre>{ 
    JSON.stringify(data, null, 2) }</pre></div>);

Working example

Memo / 16.6+

(You might even want to use a memo, 16.6+)

const PrettyPrintJson = React.memo(({data}) => (<div><pre>{
    JSON.stringify(data, null, 2) }</pre></div>));

Here's a solution that builds off many of the excellent answers. This option is jQuery free, and dynamic, not requiring you to specifically target elements by id.

1) Add your reCAPTCHA markup as you normally would:

<div class="g-recaptcha" data-sitekey="YOUR_KEY_HERE"></div>

2) Add the following into the document. It will work in any browser that supports the querySelectorAll API

<script src="https://www.google.com/recaptcha/api.js?onload=renderRecaptchas&render=explicit" async defer></script>
<script>
    window.renderRecaptchas = function() {
        var recaptchas = document.querySelectorAll('.g-recaptcha');
        for (var i = 0; i < recaptchas.length; i++) {
            grecaptcha.render(recaptchas[i], {
                sitekey: recaptchas[i].getAttribute('data-sitekey')
            });
        }
    }
</script>

I currently also have that requirement of waiting for some services to be up and running before others start. Also read the suggestions here and on some other places. But most of them require that the docker-compose.yml some how has to be changed a bit. So I started working on a solution which I consider to be an orchestration layer around docker-compose itself and I finally came up with a shell script which I called docker-compose-profile. It can wait for tcp connection to a certain container even if the service does not expose any port to the host directy. The trick I am using is to start another docker container inside the stack and from there I can (usually) connect to every service (as long no other network configuration is applied). There is also waiting method to watch out for a certain log message. Services can be grouped together to be started in a single step before another step will be triggered to start. You can also exclude some services without listing all other services to start (like a collection of available services minus some excluded services). This kind of configuration can be bundled to a profile. There is a yaml configuration file called dcp.yml which (for now) has to be placed aside your docker-compose.yml file.

For your question this would look like:

command:
  aliases:
    upd:
      command: "up -d"
      description: |
        Create and start container. Detach afterword.

profiles:
  default:
    description: |
      Wait for rabbitmq before starting worker.
    command: upd
    steps:
      - label: only-rabbitmq
        only: [ rabbitmq ]
        wait:
          - 5@tcp://rabbitmq:5432
      - label: all-others

You could now start your stack by invoking

dcp -p default upd

or even simply by

dcp

as there is only a default profile to run up -d on.

There is a tiny problem. My current version does not (yet) support special waiting condition like the ony You actually need. So there is no test to send a message to rabbit.

I have been already thinking about a further waiting method to run a certain command on host or as a docker container. Than we could extend that tool by something like

...
        wait:
          - service: rabbitmq
            method: container
            timeout: 5
            image: python-test-rabbit
...

having a docker image called python-test-rabbit that does your check.

The benefit then would be that there is no need anymore to bring the waiting part to your worker. It would be isolated and stay inside the orchestration layer.

May be someone finds this helpful to use. Any suggestions are very welcome.

cfeduke notes the possibility of calling GetPEKind. It's potentially interesting to do this from PowerShell.

Here, for example, is code for a cmdlet that could be used: https://stackoverflow.com/a/16181743/64257

Alternatively, at https://stackoverflow.com/a/4719567/64257 it is noted that "there's also the Get-PEHeader cmdlet in the PowerShell Community Extensions that can be used to test for executable images."

Use:

File.ReadAllLines("My textfile.txt");

To add to tacaswell's answer, the colorbar() function has an optional cax input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')

cax.set_xlabel('data label')  # cax == cb.ax

The click event is not bound to your new element, use a jQuery.on to handle the click.

"Is the order of elements in a JSON list maintained?" is not a good question. You need to ask "Is the order of elements in a JSON list maintained when doing [...] ?" As Felix King pointed out, JSON is a textual data format. It doesn't mutate without a reason. Do not confuse a JSON string with a (JavaScript) object.

You're probably talking about operations like JSON.stringify(JSON.parse(...)). Now the answer is: It depends on the implementation. 99%* of JSON parsers do not maintain the order of objects, and do maintain the order of arrays, but you might as well use JSON to store something like

{

    "daughter": "Julia",
    "son": "Tom",

}

and use a parser that maintains order of objects.

I found hitting ctrl+break while the macro wasn't running fixed the problem.

You had better use find_library command instead of link_directories. Concretely speaking there are two ways:

1. designate the path within the command

   find_library(NAMES gtest PATHS path1 path2 ... pathN)

2. set the variable CMAKE_LIBRARY_PATH

   set(CMAKE_LIBRARY_PATH path1 path2)
   find_library(NAMES gtest)

the reason is as flowings:

Note This command is rarely necessary and should be avoided where there are other choices. Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. The find_library() command provides the full path, which can generally be used directly in calls to target_link_libraries(). Situations where a library search path may be needed include: Project generators like Xcode where the user can switch target architecture at build time, but a full path to a library cannot be used because it only provides one architecture (i.e. it is not a universal binary).

Libraries may themselves have other private library dependencies that expect to be found via RPATH mechanisms, but some linkers are not able to fully decode those paths (e.g. due to the presence of things like $ORIGIN).

If a library search path must be provided, prefer to localize the effect where possible by using the target_link_directories() command rather than link_directories(). The target-specific command can also control how the search directories propagate to other dependent targets.

Basically like this,

<?php
$link = ""; // Link goes here!
print "<a href="'.$link.'">Link</a>";
?>

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

Check out this issue. I think the bug will be resolved when new template precompilation logic will be implemented. For now I think the best you can do is to wrap your template into <div class="root"> and style this div:

@Component({ ... })
@View({
  template: `
    <div class="root">
      <h2>Hello Angular2!</h2>
      <p>here is your template</p>
    </div>
  `,
  styles: [`
    .root {
      background: blue;
    }
  `],
   ...
})
class SomeComponent {}

See this plunker

https://facebook.github.io/react/docs/jsx-in-depth.html#javascript-expressions

You can pass any JavaScript expression as children, by enclosing it within {}. For example, these expressions are equivalent:

<MyComponent>foo</MyComponent>

<MyComponent>{'foo'}</MyComponent>

This is often useful for rendering a list of JSX expressions of arbitrary length. For example, this renders an HTML list:

function Item(props) {
  return <li>{props.message}</li>;
}

function TodoList() {
  const todos = ['finish doc', 'submit pr', 'nag dan to review'];
  return (
    <ul>
      {todos.map((message) => <Item key={message} message={message} />)}
    </ul>
  );
}

class First extends React.Component {_x000D_
  constructor(props) {_x000D_
    super(props);_x000D_
    this.state = {_x000D_
      data: [{name: 'bob'}, {name: 'chris'}],_x000D_
    };_x000D_
  }_x000D_
  _x000D_

bit long, it works i guess...

prices = [5, 12, 45]
names = []
for i, _ in enumerate(prices):
    names.append("price"+str(i+1))
dict = {}
for name, price in zip(names, prices):
    dict[name] = price
for item in dict:
    print(item, "=", dict[item])

Here's an example to add on to what others have already written. Suppose you want to make an array of functions, adderFunctions, where each function takes a single Number argument and returns the sum of the argument and the function's index in the array. Trying to generate adderFunctions with a loop using the var keyword won't work the way someone might naïvely expect:

// An array of adder functions.
var adderFunctions = [];

for (var i = 0; i < 1000; i++) {
  // We want the function at index i to add the index to its argument.
  adderFunctions[i] = function(x) {
    // What is i bound to here?
    return x + i;
  };
}

var add12 = adderFunctions[12];

// Uh oh. The function is bound to i in the outer scope, which is currently 1000.
console.log(add12(8) === 20); // => false
console.log(add12(8) === 1008); // => true
console.log(i); // => 1000

// It gets worse.
i = -8;
console.log(add12(8) === 0); // => true

The process above doesn't generate the desired array of functions because i's scope extends beyond the iteration of the for block in which each function was created. Instead, at the end of the loop, the i in each function's closure refers to i's value at the end of the loop (1000) for every anonymous function in adderFunctions. This isn't what we wanted at all: we now have an array of 1000 different functions in memory with exactly the same behavior. And if we subsequently update the value of i, the mutation will affect all the adderFunctions.

However, we can try again using the let keyword:

// Let's try this again.
// NOTE: We're using another ES6 keyword, const, for values that won't
// be reassigned. const and let have similar scoping behavior.
const adderFunctions = [];

for (let i = 0; i < 1000; i++) {
  // NOTE: We're using the newer arrow function syntax this time, but 
  // using the "function(x) { ..." syntax from the previous example 
  // here would not change the behavior shown.
  adderFunctions[i] = x => x + i;
}

const add12 = adderFunctions[12];

// Yay! The behavior is as expected. 
console.log(add12(8) === 20); // => true

// i's scope doesn't extend outside the for loop.
console.log(i); // => ReferenceError: i is not defined

This time, i is rebound on each iteration of the for loop. Each function now keeps the value of i at the time of the function's creation, and adderFunctions behaves as expected.

Now, image mixing the two behaviors and you'll probably see why it's not recommended to mix the newer let and const with the older var in the same script. Doing so can result is some spectacularly confusing code.

const doubleAdderFunctions = [];

for (var i = 0; i < 1000; i++) {
    const j = i;
    doubleAdderFunctions[i] = x => x + i + j;
}

const add18 = doubleAdderFunctions[9];
const add24 = doubleAdderFunctions[12];

// It's not fun debugging situations like this, especially when the
// code is more complex than in this example.
console.log(add18(24) === 42); // => false
console.log(add24(18) === 42); // => false
console.log(add18(24) === add24(18)); // => false
console.log(add18(24) === 2018); // => false
console.log(add24(18) === 2018); // => false
console.log(add18(24) === 1033); // => true
console.log(add24(18) === 1030); // => true

Don't let this happen to you. Use a linter.

NOTE: This is a teaching example intended to demonstrate the var/let behavior in loops and with function closures that would also be easy to understand. This would be a terrible way to add numbers. But the general technique of capturing data in anonymous function closures might be encountered in the real world in other contexts. YMMV.

You can use PHPunit default way of showing messages to debug your variables inside your test like this:

$this->assertTrue(false,$your_variable);

One alternative is to suppress the error and also throw an exception which you can catch later. This is especially useful if there are multiple calls to file_get_contents() in your code, since you don't need to suppress and handle all of them manually. Instead, several calls can be made to this function in a single try/catch block.

// Returns the contents of a file
function file_contents($path) {
    $str = @file_get_contents($path);
    if ($str === FALSE) {
        throw new Exception("Cannot access '$path' to read contents.");
    } else {
        return $str;
    }
}

// Example
try {
    file_contents("a");
    file_contents("b");
    file_contents("c");
} catch (Exception $e) {
    // Deal with it.
    echo "Error: " , $e->getMessage();
}

A date-time object is supposed to store the information about the date, time, timezone etc., not about the formatting. You can format a date-time object into a String with the pattern of your choice using date-time formatting API.

• The date-time formatting API for the modern date-time types is in the package, java.time.format e.g. java.time.format.DateTimeFormatter, java.time.format.DateTimeFormatterBuilder etc.
• The date-time formatting API for the legacy date-time types is in the package, java.text e.g. java.text.SimpleDateFormat, java.text.DateFormat etc.

Demo using modern API:

import java.time.LocalDate;
import java.time.Month;
import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Locale;

public class Main {
    public static void main(String[] args) {
        ZonedDateTime zdt = ZonedDateTime.of(LocalDate.of(2012, Month.DECEMBER, 1).atStartOfDay(),
                ZoneId.of("Europe/London"));

        // Default format returned by Date#toString
        System.out.println(zdt);

        // Custom format
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd", Locale.ENGLISH);
        String formattedDate = dtf.format(zdt);
        System.out.println(formattedDate);
    }
}

Output:

2012-12-01T00:00Z[Europe/London]
2012-12-01

Learn about the modern date-time API from Trail: Date Time.

Demo using legacy API:

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
import java.util.TimeZone;

public class Main {
    public static void main(String[] args) {
        Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        calendar.setTimeInMillis(0);
        calendar.set(Calendar.YEAR, 2012);
        calendar.set(Calendar.MONTH, 11);
        calendar.set(Calendar.DAY_OF_MONTH, 1);
        Date date = calendar.getTime();

        // Default format returned by Date#toString
        System.out.println(date);

        // Custom format
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
        String formattedDate = sdf.format(date);
        System.out.println(formattedDate);
    }
}

Output:

Sat Dec 01 00:00:00 GMT 2012
2012-12-01

Some more important points:

1. The java.util.Date object is not a real date-time object like the modern date-time types; rather, it represents the milliseconds from the Epoch of January 1, 1970. When you print an object of java.util.Date, its toString method returns the date-time calculated from this milliseconds value. Since java.util.Date does not have timezone information, it applies the timezone of your JVM and displays the same. If you need to print the date-time in a different timezone, you will need to set the timezone to SimpleDateFomrat and obtain the formatted string from it.
2. The date-time API of java.util and their formatting API, SimpleDateFormat are outdated and error-prone. It is recommended to stop using them completely and switch to the modern date-time API.
   • For any reason, if you have to stick to Java 6 or Java 7, you can use ThreeTen-Backport which backports most of the java.time functionality to Java 6 & 7.
   • If you are working for an Android project and your Android API level is still not compliant with Java-8, check Java 8+ APIs available through desugaring and How to use ThreeTenABP in Android Project.

This post is just an observation for Python behaviour I encountered. Maybe the advices you read above don't work for you if you made the same thing I did below.

Namely, I have a module which contains global/shared variables (as suggested above):

#sharedstuff.py

globaltimes_randomnode=[]
globalist_randomnode=[]

Then I had the main module which imports the shared stuff with:

import sharedstuff as shared

and some other modules that actually populated these arrays. These are called by the main module. When exiting these other modules I can clearly see that the arrays are populated. But when reading them back in the main module, they were empty. This was rather strange for me (well, I am new to Python). However, when I change the way I import the sharedstuff.py in the main module to:

from globals import *

it worked (the arrays were populated).

Just sayin'

Customizing CORS for Angular 5 and Spring Security (Cookie base solution)

On the Angular side required adding option flag withCredentials: true for Cookie transport:

constructor(public http: HttpClient) {
}

public get(url: string = ''): Observable<any> {
    return this.http.get(url, { withCredentials: true });
}

On Java server-side required adding CorsConfigurationSource for configuration CORS policy:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        // This Origin header you can see that in Network tab
        configuration.setAllowedOrigins(Arrays.asList("http:/url_1", "http:/url_2")); 
        configuration.setAllowedMethods(Arrays.asList("GET","POST"));
        configuration.setAllowedHeaders(Arrays.asList("content-type"));
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and()...
    }
}

Method configure(HttpSecurity http) by default will use corsConfigurationSource for http.cors()

There are several good answers here, so let me provide a terrible one:

: you can type in anything below, doesnt have to match anything

yum whatprovides "me with a life"

: result of the above (some liberties taken with spacing):

: the key result above is that "primary_db" files were downloaded

: filelists are downloaded EVEN IF you have keepcache=0 in your yum.conf

: note you can limit this to "primary_db.sqlite" if you really want

find /var/cache/yum -name '*.sqlite'

: if you download/install a new repo, run the exact same command again
: to get the databases for the new repo

: if you know sqlite you can stop reading here

: if not heres a sample command to dump the contents

echo 'SELECT packages.name, GROUP_CONCAT(files.name, ", ") AS files FROM files JOIN packages ON (files.pkgKey = packages.pkgKey) GROUP BY packages.name LIMIT 10;' | sqlite3 -line /var/cache/yum/x86_64/7/base/gen/primary_db.sqlite 

: remove "LIMIT 10" above for the whole list

: format chosen for proof-of-concept purposes, probably can be improved a lot

you can try this:"Filename.txt" file will be created automatically in the bin->debug folder everytime you run this code or you can specify path of the file like: @"C:/...". you can check ëxistance of "Hello" by going to the bin -->debug folder

P.S dont forget to add Console.Readline() after this code snippet else console will not appear.

TextWriter tw = new StreamWriter("filename.txt");
        String text = "Hello";
        tw.WriteLine(text);
        tw.Close();

        TextReader tr = new StreamReader("filename.txt");
        Console.WriteLine(tr.ReadLine());
        tr.Close();

I extended Carlos LM's solution a bit so it's more detailed.

Example of a schema:

var schema = {
    _id: 123,
    id: 12,
    t: 'title',
    p: 4.5,
    ls: [{
            l: 'lemma',
            p: {
                pp: 8.9
            }
        },
         {
            l: 'lemma2',
            p: {
               pp: 8.3
           }
        }
    ]
};

Type into the console:

var schemafy = function(schema, i, limit) {
    var i = (typeof i !== 'undefined') ? i : 1;
    var limit = (typeof limit !== 'undefined') ? limit : false;
    var type = '';
    var array = false;

    for (key in schema) {
        type = typeof schema[key];
        array = (schema[key] instanceof Array) ? true : false;

        if (type === 'object') {
            print(Array(i).join('    ') + key+' <'+((array) ? 'array' : type)+'>:');
            schemafy(schema[key], i+1, array);
        } else {
            print(Array(i).join('    ') + key+' <'+type+'>');
        }

        if (limit) {
            break;
        }
    }
}

Run:

schemafy(db.collection.findOne());

Output

_id <number>
id <number>
t <string>
p <number>
ls <object>:
    0 <object>:
    l <string>
    p <object>:
        pp <number> 

If you are using laragon open the php.ini

In the interface of laragon menu-> php-> php.ini

when you open the file look for ; extension_dir = "./"

create another one without **; ** with the path of your php version to the folder ** ext ** for example

extension_dir = "C: \ laragon \ bin \ php \ php-7.3.11-Win32-VC15-x64 \ ext"

change it save it

Just a few suggestions:

• Screenshots might be an easy way, but you'll have to make sure the code in the image is big enough and clear enough to read. (not the whole screenshot, just the relevant part)
• If you can embed html then there are lots of tools to generate syntax highlighted html.

My use case is that I'm on a metered account. Data transfer is limited on weekdays, Mon - Fri, from 6am - 6pm. I am using bandwidth limiting, but somehow, data still slips through, about 1GB per day!

I strongly suspected it's sickrage or sickbeard, doing a high amount of searches. My download machine is called "download." The following was my solution, using the above,for starting, and stopping the download VM, using KVM:

# Stop download Mon-Fri, 6am
0 6 * * 1,2,3,4,5 root          virsh shutdown download
# Start download Mon-Fri, 6pm
0 18 * * 1,2,3,4,5 root         virsh start download

I think this is correct, and hope it helps someone else too.

ElektroStudios answer is a bit misleading.

"when you launch a bat file the working dir is the dir where it was launched" This is true if the user clicks on the batch file in the explorer.

However, if the script is called from another script using the CALL command, the current working directory does not change.

Thus, inside your script, it is better to use %~dp0subfolder\file1.txt

Please also note that %~dp0 will end with a backslash when the current script is not in the current working directory. Thus, if you need the directory name without a trailing backslash, you could use something like

call :GET_THIS_DIR
echo I am here: %THIS_DIR%
goto :EOF

:GET_THIS_DIR
pushd %~dp0
set THIS_DIR=%CD%
popd
goto :EOF

by now the mounting works on some machines (ubuntu) and some doesn't (centos 7) but installing the plugin solves it

vagrant plugin install vagrant-vbguest

without having to do anything else on top of that, just

vagrant reload

A View in Oracle and in other database systems is simply the representation of a SQL statement that is stored in memory so that it can easily be re-used. For example, if we frequently issue the following query

SELECT customerid, customername FROM customers WHERE countryid='US';

To create a view use the CREATE VIEW command as seen in this example

CREATE VIEW view_uscustomers
AS
SELECT customerid, customername FROM customers WHERE countryid='US';

This command creates a new view called view_uscustomers. Note that this command does not result in anything being actually stored in the database at all except for a data dictionary entry that defines this view. This means that every time you query this view, Oracle has to go out and execute the view and query the database data. We can query the view like this:

SELECT * FROM view_uscustomers WHERE customerid BETWEEN 100 AND 200;

And Oracle will transform the query into this:

SELECT * 
FROM (select customerid, customername from customers WHERE countryid='US') 
WHERE customerid BETWEEN 100 AND 200

Benefits of using Views

• Commonality of code being used. Since a view is based on one common set of SQL, this means that when it is called it’s less likely to require parsing.
• Security. Views have long been used to hide the tables that actually contain the data you are querying. Also, views can be used to restrict the columns that a given user has access to.
• Predicate pushing

You can find advanced topics in this article about "How to Create and Manage Views in Oracle."

Its always better to go for a generic reusable function in your project which returns whether the extension loaded. You can use the following function to check -

function isExtensionLoaded($extension_name){
    return extension_loaded($extension_name);
}

Usage

echo isExtensionLoaded('curl');
echo isExtensionLoaded('gd');

Two-way binding means that any data-related changes affecting the model are immediately propagated to the matching view(s), and that any changes made in the view(s) (say, by the user) are immediately reflected in the underlying model. When app data changes, so does the UI, and conversely.

This is a very solid concept to build a web application on top of, because it makes the "Model" abstraction a safe, atomic data source to use everywhere within the application. Say, if a model, bound to a view, changes, then its matching piece of UI (the view) will reflect that, no matter what. And the matching piece of UI (the view) can safely be used as a mean of collecting user inputs/data, so as to maintain the application data up-to-date.

A good two-way binding implementation should obviously make this connection between a model and some view(s) as simple as possible, from a developper point of view.

It is then quite untrue to say that Backbone does not support two-way binding: while not a core feature of the framework, it can be performed quite simply using Backbone's Events though. It costs a few explicit lines of code for the simple cases; and can become quite hazardous for more complex bindings. Here is a simple case (untested code, written on the fly just for the sake of illustration):

Model = Backbone.Model.extend
  defaults:
    data: ''

View = Backbone.View.extend
  template: _.template("Edit the data: <input type='text' value='<%= data %>' />")

  events:
    # Listen for user inputs, and edit the model.
    'change input': @setData

  initialize: (options) ->
    # Listen for model's edition, and trigger UI update
    @listenTo @model, 'change:data', @render

  render: ->
    @$el.html @template(@model.attributes)
    @

  setData: (e) =>
    e.preventDefault()
    @model.set 'data', $(e.currentTarget).value()

model: new Model()
view = new View {el: $('.someEl'), model: model}

This is a pretty typical pattern in a raw Backbone application. As one can see, it requires a decent amount of (pretty standard) code.

AngularJS and some other alternatives (Ember, Knockout…) provide two-way binding as a first-citizen feature. They abstract many edge-cases under some DSL, and do their best at integrating two-way binding within their ecosystem. Our example would look something like this with AngularJS (untested code, see above):

<div ng-app="app" ng-controller="MainCtrl">
  Edit the data:
  <input name="mymodel.data" ng-model="mymodel.data">
</div>

angular.module('app', [])
  .controller 'MainCtrl', ($scope) ->
    $scope.mymodel = {data: ''}

Rather short!

But, be aware that some fully-fledged two-way binding extensions do exist for Backbone as well (in raw, subjective order of decreasing complexity): Epoxy, Stickit, ModelBinder…

One cool thing with Epoxy, for instance, is that it allows you to declare your bindings (model attributes <-> view's DOM element) either within the template (DOM), or within the view implementation (JavaScript). Some people strongly dislike adding "directives" to the DOM/template (such as the ng-* attributes required by AngularJS, or the data-bind attributes of Ember).

Taking Epoxy as an example, one can rework the raw Backbone application into something like this (…):

Model = Backbone.Model.extend
  defaults:
    data: ''

View = Backbone.Epoxy.View.extend
  template: _.template("Edit the data: <input type='text' />")
  # or, using the inline form: <input type='text' data-bind='value:data' />

  bindings:
    'input': 'value:data'

  render: ->
    @$el.html @template(@model.attributes)
    @

model: new Model()
view = new View {el: $('.someEl'), model: model}

All in all, pretty much all "mainstream" JS frameworks support two-way binding. Some of them, such as Backbone, do require some extra work to make it work smoothly, but those are the same which do not enforce a specific way to do it, to begin with. So it is really about your state of mind.

Also, you may be interested in Flux, a different architecture for web applications promoting one-way binding through a circular pattern. It is based on the concept of fast, holistic re-rendering of UI components upon any data change to ensure cohesiveness and make it easier to reason about the code/dataflow. In the same trend, you might want to check the concept of MVI (Model-View-Intent), for instance Cycle.

Bootstrap 3 introduces responsive tables:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

Bootstrap 4 is similar, but with more control via some new classes:

...responsive across all viewports ... with .table-responsive. Or, pick a maximum breakpoint with which to have a responsive table up to by using .table-responsive{-sm|-md|-lg|-xl}.

Credit to Jason Bradley for providing an example:

The best answer here is to use all(), which is the builtin for this situation. We combine this with a generator expression to produce the result you want cleanly and efficiently. For example:

>>> items = [[1, 2, 0], [1, 2, 0], [1, 2, 0]]
>>> all(flag == 0 for (_, _, flag) in items)
True
>>> items = [[1, 2, 0], [1, 2, 1], [1, 2, 0]]
>>> all(flag == 0 for (_, _, flag) in items)
False

Note that all(flag == 0 for (_, _, flag) in items) is directly equivalent to all(item[2] == 0 for item in items), it's just a little nicer to read in this case.

And, for the filter example, a list comprehension (of course, you could use a generator expression where appropriate):

>>> [x for x in items if x[2] == 0]
[[1, 2, 0], [1, 2, 0]]

If you want to check at least one element is 0, the better option is to use any() which is more readable:

>>> any(flag == 0 for (_, _, flag) in items)
True

A pertinent quote from PEP 465 - A dedicated infix operator for matrix multiplication , as mentioned by @petr-viktorin, clarifies the problem the OP was getting at:

[...] numpy provides two different types with different __mul__ methods. For numpy.ndarray objects, * performs elementwise multiplication, and matrix multiplication must use a function call (numpy.dot). For numpy.matrix objects, * performs matrix multiplication, and elementwise multiplication requires function syntax. Writing code using numpy.ndarray works fine. Writing code using numpy.matrix also works fine. But trouble begins as soon as we try to integrate these two pieces of code together. Code that expects an ndarray and gets a matrix, or vice-versa, may crash or return incorrect results

The introduction of the @ infix operator should help to unify and simplify python matrix code.

You should find out last timestamp values in each group (subquery), and then join this subquery to the table -

SELECT t1.* FROM messages t1
  JOIN (SELECT from_id, MAX(timestamp) timestamp FROM messages GROUP BY from_id) t2
    ON t1.from_id = t2.from_id AND t1.timestamp = t2.timestamp;

Run the following commands in guest machine/VM:

wget https://raw.githubusercontent.com/mitchellh/vagrant/master/keys/vagrant.pub -O ~/.ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
chown -R vagrant:vagrant ~/.ssh

Then do vagrant halt. This will remove and regenerate your private keys.

(These steps assume you have already created or already have the ~/.ssh/ and ~/.ssh/authorized_keys directories under your home folder.)

Yes: you can sort using a custom comparison function:

std::sort(info.begin(), info.end(), my_custom_comparison);

my_custom_comparison needs to be a function or a class with an operator() overload (a functor) that takes two data objects and returns a bool indicating whether the first is ordered prior to the second (i.e., first < second). Alternatively, you can overload operator< for your class type data; operator< is the default ordering used by std::sort.

Either way, the comparison function must yield a strict weak ordering of the elements.

Your great great great great great great great grandfather should upgrade to SQL Server 2008 and use the DateTime2 data type, which supports dates in the range: 0001-01-01 through 9999-12-31.

One of the things to also keep in mind is that when you have Visual Studio 2010 SP1 installed some C++ compilers and libraries may have been removed. There's been an update made available by Microsoft to make sure those are brought back to your system.

Install this update to restore the Visual C++ compilers and libraries that may have been removed when Visual Studio 2010 Service Pack 1 (SP1) was installed. The compilers and libraries are part of the Microsoft Windows Software Development Kit for Windows 7 and the .NET Framework 4 (later referred to as the Windows SDK 7.1).

Also, when you read the VS2010 SP1 README you'll also notice that some notes have been made in regards to the Windows 7 SDK (See section 2.2.1) installation. It may be that one of these conditions may apply to you and therefore may need to uncheck the C++ compiler-checkbox as the SDK installer will attempt to install an older version of compilers ÓR you may need to uninstall VS2010 SP1 and re-run the SDK 7.1 installation, repair or modification.

Condition 1: If the Visual C++ Compilers checkbox is selected when the Windows SDK 7.1 is installed, repaired, or modified after Visual Studio 2010 SP1 has been installed, the error may be encountered and some selected components may not be installed.

Workaround: Clear the Visual C++ Compilers checkbox before you run the Windows SDK 7.1 installation, repair, or modification.

Condition 2: If the Visual C++ Compilers checkbox is selected when the Windows SDK 7.1 is installed, repaired, or modified after Visual Studio 2010 has been installed but Visual Studio 2010 SP1 has not been uninstalled, the error may be encountered.

Workaround: Uninstall Visual Studio 2010 SP1 and then rerun the Windows SDK 7.1 installation, repair, or modification.

However, even then I found that I still needed to uninstall any existing Visual C++ 2010 redistributables, as has been suggested by mgrandi.

Easiest way to get it done is by adding required into your select

Select the best option
<br/>

<select name="dd1" id="dd1" required>
<option value="none">None</option>
<option value="o1">option 1</option>
<option value="o2">option 2</option>
<option value="o3">option 3</option>
</select>

For me debug_backtrace was hitting my memory limit, and I wanted to use this in production to log and email errors as they happen.

Instead I found this solution which works brilliantly!

// Make a new exception at the point you want to trace, and trace it!
$e = new Exception;
var_dump($e->getTraceAsString());

// Outputs the following

In javafx (using Gluon), the height is set at runtime or something like it. While being able to get the width just like normal...

double width = appBar.getWidth();

You have to create a listener:

GluonApplication application = this;

application.getAppBar().heightProperty().addListener(new ChangeListener(){
    @Override
    public void changed(ObservableValue observable, Object oldValue, Object newValue) {
        // Take most recent value given here
        application.getAppBar.heightProperty.get()
    }
});

...And take the most recent value it changed to. To get the height.

Here is a Swift way to get screen sizes, this also takes current interface orientation into account:

var screenWidth: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.width
    } else {
        return UIScreen.mainScreen().bounds.size.height
    }
}
var screenHeight: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.height
    } else {
        return UIScreen.mainScreen().bounds.size.width
    }
}
var screenOrientation: UIInterfaceOrientation {
    return UIApplication.sharedApplication().statusBarOrientation
}

These are included as a standard function in:

That's probably a requireJS module definition

Check here for more details

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.

Following Code work for me.

Update:

As I am calling a free API request (json base ) IpStack.

    public static string CityStateCountByIp(string IP)
    {
      //var url = "http://freegeoip.net/json/" + IP;
      //var url = "http://freegeoip.net/json/" + IP;
        string url = "http://api.ipstack.com/" + IP + "?access_key=[KEY]";
        var request = System.Net.WebRequest.Create(url);
        
         using (WebResponse wrs = request.GetResponse())
         using (Stream stream = wrs.GetResponseStream())
         using (StreamReader reader = new StreamReader(stream))
         {
          string json = reader.ReadToEnd();
          var obj = JObject.Parse(json);
            string City = (string)obj["city"];
            string Country = (string)obj["region_name"];                    
            string CountryCode = (string)obj["country_code"];
        
           return (CountryCode + " - " + Country +"," + City);
           }

  return "";

}

Edit : First, it was http://freegeoip.net/ now it's https://ipstack.com/ (and maybe now it's a paid service- Free Up to 10,000 request/month)

intutils.ToFloat32

// ToFloat32 converts a int num to a float32 num
func ToFloat32(in int) float32 {
    return float32(in)
}

// ToFloat64 converts a int num to a float64 num
func ToFloat64(in int) float64 {
    return float64(in)
}

Use COALESCE() instead:

SELECT COALESCE(Field,'Empty') from Table;

It functions much like ISNULL, although provides more functionality. Coalesce will return the first non null value in the list. Thus:

SELECT COALESCE(null, null, 5); 

returns 5, while

SELECT COALESCE(null, 2, 5);

returns 2

Coalesce will take a large number of arguments. There is no documented maximum. I tested it will 100 arguments and it succeeded. This should be plenty for the vast majority of situations.

Unfortunately MySQL does not feature a split string function. However you can create a user defined function for this, such as the one described in the following article:

• MySQL Split String Function by Federico Cargnelutti

With that function:

DELIMITER $$

CREATE FUNCTION SPLIT_STR(
  x VARCHAR(255),
  delim VARCHAR(12),
  pos INT
)
RETURNS VARCHAR(255) DETERMINISTIC
BEGIN 
    RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos),
       LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1),
       delim, '');
END$$

DELIMITER ;

you would be able to build your query as follows:

SELECT SPLIT_STR(membername, ' ', 1) as memberfirst,
       SPLIT_STR(membername, ' ', 2) as memberlast
FROM   users;

If you prefer not to use a user defined function and you do not mind the query to be a bit more verbose, you can also do the following:

SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(membername, ' ', 1), ' ', -1) as memberfirst,
       SUBSTRING_INDEX(SUBSTRING_INDEX(membername, ' ', 2), ' ', -1) as memberlast
FROM   users;
