I don't think it's enough merely to get the response. I think you need to read it (get the entity and read it via EntityUtils.consume()).

e.g. (from the doc)

     System.out.println("<< Response: " + response.getStatusLine());
     System.out.println(EntityUtils.toString(response.getEntity()));

It is not possible. §2.3 says that "." is an unreserved character and that "URIs that differ in the replacement of an unreserved character with its corresponding percent-encoded US-ASCII octet are equivalent". Therefore, /%2E%2E/ is the same as /../, and that will get normalized away.

(This is a combination of an answer by bobince and a comment by slowpoison.)

You could just try using return false (return false overrides default behaviour on every DOM element) like that :

myform.onsubmit = function ()
{ 
  // do what you want
  return false
}

and then submit your form using myform.submit()

or alternatively :

mybutton.onclick = function () 
{
   // do what you want
   return false
}

Also, if you use type="button" your form will not be submitted.

Suggestions:

• Don't use Canvas as you shouldn't mix AWT with Swing components unnecessarily.
• Instead use a JPanel or JComponent.
• Don't get your Graphics object by calling getGraphics() on a component as the Graphics object obtained will be transient.
• Draw in the JPanel's paintComponent() method.
• All this is well explained in several tutorials that are easily found. Why not read them first before trying to guess at this stuff?

U can use

  $(document).on('click','p.class',function(e){
   e.preventDefault();

   });

I improved upon psycho brm's filterByData extension to jQuery.

Where the former extension searched on a key-value pair, with this extension you can additionally search for the presence of a data attribute, irrespective of its value.

(function ($) {

    $.fn.filterByData = function (prop, val) {
        var $self = this;
        if (typeof val === 'undefined') {
            return $self.filter(
                function () { return typeof $(this).data(prop) !== 'undefined'; }
            );
        }
        return $self.filter(
            function () { return $(this).data(prop) == val; }
        );
    };

})(window.jQuery);

Usage:

$('<b>').data('x', 1).filterByData('x', 1).length    // output: 1
$('<b>').data('x', 1).filterByData('x').length       // output: 1

// test data_x000D_

Thanks! This solved a similar problem I had with a data attribute inside a Div.

<div id="prop_sample" data-want="data I want">data I do not want</div>

Use this xpath: //*[@id="prop_sample"]/@data-want

Hope this helps someone else!

It means the value of data is None.

I just had a quick look at your example, but if i understood it the right way you're trying to add 404 routes to dynamic segments. I had the same issue a couple of days ago, found #458 and #1103 and ended up with a hand made check within the render function:

if (!place) return <NotFound />;

hope that helps!

Try Toad for MySQL - its free and its great.

the function Position in funprog {base} also does the job. It allows you to pass an arbitrary function, and returns the first or last match.

Position(f, x, right = FALSE, nomatch = NA_integer)

In my workflow, I add a Dockerfile for each part of my system and configure it that each part could run individually. Then I add a docker-compose.yml to bring them together and link them.

Biggest advantage (in my opinion): when linking the containers, you can define a name and ping your containers with this name. Therefore your database might be accessible with the name db and no longer by its IP.

Elaborateling slighty on the nice answer by Jon Skeet, this could be versatile:

public static IEnumerable<T> Directional<T>(this IList<T> items, bool Forwards) {
    if (Forwards) foreach (T item in items) yield return item;
    else for (int i = items.Count-1; 0<=i; i--) yield return items[i];
}

And then use as

foreach (var item in myList.Directional(forwardsCondition)) {
    .
    .
}

You can bind to dom directly

<div dangerouslySetInnerHTML={{__html: '<p>First &middot; Second</p>'}}></div>

If you want to display a single character then you can also use name[0] instead of using pointer.

It will serve your purpose but if you want to display full string using %c, you can try this:

#include<stdio.h>
void main()
{ 
    char name[]="siva";
    int i;
    for(i=0;i<4;i++)
    {
        printf("%c",*(name+i));
    }
} 

It happened to me, and turned out it was because of Charles Proxy.

Charles Proxy is a HTTP debugging proxy server application

Solution (only if you have Charles Proxy installed):

1. Shut down Charles Proxy;
2. Restart Android Studio.

Quoted from https://developer.mozilla.org/en/DOM/element.click

The click method is intended to be used with INPUT elements of type button, checkbox, radio, reset or submit. Gecko does not implement the click method on other elements that might be expected to respond to mouse–clicks such as links (A elements), nor will it necessarily fire the click event of other elements.

Non–Gecko DOMs may behave differently.

Unfortunately it sounds like you have already discovered the best solution to your problem.

As a side note, I agree that your solution seems less than ideal, but if you encapsulate the functionality inside a method (much like JQuery would do) it is not so bad.

I was trying to find a better answer that was more standalone, so I started to think about how JQuery does events and custom events. Since click (from JQuery) is just any event, I thought that all I had to do was trigger the event given that the iframe's content has been clicked on. Thus, this was my solution

$(document).ready(function () {
    $("iframe").each(function () {
        //Using closures to capture each one
        var iframe = $(this);
        iframe.on("load", function () { //Make sure it is fully loaded
            iframe.contents().click(function (event) {
                iframe.trigger("click");
            });
        });

        iframe.click(function () {
            //Handle what you need it to do
        });
    });
});

Array.prototype.find is not supported in any version of IE

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find

The quotes you use are the issue:

<meta http-equiv=”refresh” content=”5" >

You should use the "

<meta http-equiv="refresh" content="5">

Avoid inline JavaScript; you can use a class:

<iframe src="..." frameborder="0" scrolling="auto" class="iframe-full-height"></iframe>

And reference it with jQuery:

$('.iframe-full-height').on('load', function(){
    this.style.height=this.contentDocument.body.scrollHeight +'px';
});

The leading 0 is leading to bash trying to interpret your number as an octal number, but octal numbers are 0-7, and 8 is thus an invalid token.

If I were you, I would add some logic to remove a leading 0, add one, and re-add the leading 0 if the result is < 10.

You may also write it in two statements if it mostly is true use:

a = 5
a = 10 if false

Or use a switch statement if you need more possibilities:

a = switch x
  when true then 5
  when false then 10

With a boolean it may be oversized but i find it very readable.

On a Scientific Linux 6.7 system, the man page on rsync says:

--ignore-times          don't skip files that match size and time

I have two files with identical contents, but with different creation dates:

[root@windstorm ~]# ls -ls /tmp/master/usercron /tmp/new/usercron
4 -rwxrwx--- 1 root root 1595 Feb 15 03:45 /tmp/master/usercron
4 -rwxrwx--- 1 root root 1595 Feb 16 04:52 /tmp/new/usercron

[root@windstorm ~]# diff /tmp/master/usercron /tmp/new/usercron
[root@windstorm ~]# md5sum /tmp/master/usercron /tmp/new/usercron
368165347b09204ce25e2fa0f61f3bbd  /tmp/master/usercron
368165347b09204ce25e2fa0f61f3bbd  /tmp/new/usercron

With --size-only, the two files are regarded the same:

[root@windstorm ~]# rsync -v --size-only -n  /tmp/new/usercron /tmp/master/usercron

sent 29 bytes  received 12 bytes  82.00 bytes/sec
total size is 1595  speedup is 38.90 (DRY RUN)

With --ignore-times, the two files are regarded different:

[root@windstorm ~]# rsync -v --ignore-times -n  /tmp/new/usercron /tmp/master/usercron
usercron

sent 32 bytes  received 15 bytes  94.00 bytes/sec
total size is 1595  speedup is 33.94 (DRY RUN)

So it does not looks like --ignore-times has any effect at all.

Seems question is not about strings equality, but of sets equality. You can compare them this way only by splitting strings and converting them to sets:

s1 = 'abc def ghi'
s2 = 'def ghi abc'
set1 = set(s1.split(' '))
set2 = set(s2.split(' '))
print set1 == set2

Result will be

True

I usually use a bat script for that. Here's what I typically use:

@echo off
set d=%~dp0
java -Xmx400m -cp "%d%myapp.jar;%d%libs/mylib.jar" my.main.Class %*

The %~dp0 extract the directory where the .bat is located. This allows the bat to find the locations of the jars without requiring any special environment variables nor the setting of the PATH variable.

EDIT: Added quotes to the classpath. Otherwise, as Joey said, "fun things can happen with spaces"

Seems like this thread is very popular and it will be sad not to mention here that there is an alternative way - ViewModel First Navigation. Most of the MVVM frameworks out there using it, however if you want to understand what it is about, continue reading.

All the official Xamarin.Forms documentation is demonstrating a simple, yet slightly not MVVM pure solution. That is because the Page(View) should know nothing about the ViewModel and vice versa. Here is a great example of this violation:

// C# version
public partial class MyPage : ContentPage
{
    public MyPage()
    {
        InitializeComponent();
        // Violation
        this.BindingContext = new MyViewModel();
    }
}

// XAML version
<?xml version="1.0" encoding="utf-8"?>
<ContentPage
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:viewmodels="clr-namespace:MyApp.ViewModel"
    x:Class="MyApp.Views.MyPage">
    <ContentPage.BindingContext>
        <!-- Violation -->
        <viewmodels:MyViewModel />
    </ContentPage.BindingContext>
</ContentPage>

If you have a 2 pages application this approach might be good for you. However if you are working on a big enterprise solution you better go with a ViewModel First Navigation approach. It is slightly more complicated but much cleaner approach that allow you to navigate between ViewModels instead of navigation between Pages(Views). One of the advantages beside clear separation of concerns is that you could easily pass parameters to the next ViewModel or execute an async initialization code right after navigation. Now to details.

(I will try to simplify all the code examples as much as possible).

1. First of all we need a place where we could register all our objects and optionally define their lifetime. For this matter we can use an IOC container, you can choose one yourself. In this example I will use Autofac(it is one of the fastest available). We can keep a reference to it in the App so it will be available globally (not a good idea, but needed for simplification):

public class DependencyResolver
{
    static IContainer container;

    public DependencyResolver(params Module[] modules)
    {
        var builder = new ContainerBuilder();

        if (modules != null)
            foreach (var module in modules)
                builder.RegisterModule(module);

        container = builder.Build();
    }

    public T Resolve<T>() => container.Resolve<T>();
    public object Resolve(Type type) => container.Resolve(type);
}

public partial class App : Application
{
    public DependencyResolver DependencyResolver { get; }

    // Pass here platform specific dependencies
    public App(Module platformIocModule)
    {
        InitializeComponent();
        DependencyResolver = new DependencyResolver(platformIocModule, new IocModule());
        MainPage = new WelcomeView();
    }

    /* The rest of the code ... */
}

2.We will need an object responsible for retrieving a Page (View) for a specific ViewModel and vice versa. The second case might be useful in case of setting the root/main page of the app. For that we should agree on a simple convention that all the ViewModels should be in ViewModels directory and Pages(Views) should be in the Views directory. In other words ViewModels should live in [MyApp].ViewModels namespace and Pages(Views) in [MyApp].Views namespace. In addition to that we should agree that WelcomeView(Page) should have a WelcomeViewModel and etc. Here is a code example of a mapper:

public class TypeMapperService
{
    public Type MapViewModelToView(Type viewModelType)
    {
        var viewName = viewModelType.FullName.Replace("Model", string.Empty);
        var viewAssemblyName = GetTypeAssemblyName(viewModelType);
        var viewTypeName = GenerateTypeName("{0}, {1}", viewName, viewAssemblyName);
        return Type.GetType(viewTypeName);
    }

    public Type MapViewToViewModel(Type viewType)
    {
        var viewModelName = viewType.FullName.Replace(".Views.", ".ViewModels.");
        var viewModelAssemblyName = GetTypeAssemblyName(viewType);
        var viewTypeModelName = GenerateTypeName("{0}Model, {1}", viewModelName, viewModelAssemblyName);
        return Type.GetType(viewTypeModelName);
    }

    string GetTypeAssemblyName(Type type) => type.GetTypeInfo().Assembly.FullName;
    string GenerateTypeName(string format, string typeName, string assemblyName) =>
        string.Format(CultureInfo.InvariantCulture, format, typeName, assemblyName);
}

3.For the case of setting a root page we will need sort of ViewModelLocator that will set the BindingContext automatically:

public static class ViewModelLocator
{
    public static readonly BindableProperty AutoWireViewModelProperty =
        BindableProperty.CreateAttached("AutoWireViewModel", typeof(bool), typeof(ViewModelLocator), default(bool), propertyChanged: OnAutoWireViewModelChanged);

    public static bool GetAutoWireViewModel(BindableObject bindable) =>
        (bool)bindable.GetValue(AutoWireViewModelProperty);

    public static void SetAutoWireViewModel(BindableObject bindable, bool value) =>
        bindable.SetValue(AutoWireViewModelProperty, value);

    static ITypeMapperService mapper = (Application.Current as App).DependencyResolver.Resolve<ITypeMapperService>();

    static void OnAutoWireViewModelChanged(BindableObject bindable, object oldValue, object newValue)
    {
        var view = bindable as Element;
        var viewType = view.GetType();
        var viewModelType = mapper.MapViewToViewModel(viewType);
        var viewModel =  (Application.Current as App).DependencyResolver.Resolve(viewModelType);
        view.BindingContext = viewModel;
    }
}

// Usage example
<?xml version="1.0" encoding="utf-8"?>
<ContentPage
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:viewmodels="clr-namespace:MyApp.ViewModel"
    viewmodels:ViewModelLocator.AutoWireViewModel="true"
    x:Class="MyApp.Views.MyPage">
</ContentPage>

4.Finally we will need a NavigationService that will support ViewModel First Navigation approach:

public class NavigationService
{
    TypeMapperService mapperService { get; }

    public NavigationService(TypeMapperService mapperService)
    {
        this.mapperService = mapperService;
    }

    protected Page CreatePage(Type viewModelType)
    {
        Type pageType = mapperService.MapViewModelToView(viewModelType);
        if (pageType == null)
        {
            throw new Exception($"Cannot locate page type for {viewModelType}");
        }

        return Activator.CreateInstance(pageType) as Page;
    }

    protected Page GetCurrentPage()
    {
        var mainPage = Application.Current.MainPage;

        if (mainPage is MasterDetailPage)
        {
            return ((MasterDetailPage)mainPage).Detail;
        }

        // TabbedPage : MultiPage<Page>
        // CarouselPage : MultiPage<ContentPage>
        if (mainPage is TabbedPage || mainPage is CarouselPage)
        {
            return ((MultiPage<Page>)mainPage).CurrentPage;
        }

        return mainPage;
    }

    public Task PushAsync(Page page, bool animated = true)
    {
        var navigationPage = Application.Current.MainPage as NavigationPage;
        return navigationPage.PushAsync(page, animated);
    }

    public Task PopAsync(bool animated = true)
    {
        var mainPage = Application.Current.MainPage as NavigationPage;
        return mainPage.Navigation.PopAsync(animated);
    }

    public Task PushModalAsync<TViewModel>(object parameter = null, bool animated = true) where TViewModel : BaseViewModel =>
        InternalPushModalAsync(typeof(TViewModel), animated, parameter);

    public Task PopModalAsync(bool animated = true)
    {
        var mainPage = GetCurrentPage();
        if (mainPage != null)
            return mainPage.Navigation.PopModalAsync(animated);

        throw new Exception("Current page is null.");
    }

    async Task InternalPushModalAsync(Type viewModelType, bool animated, object parameter)
    {
        var page = CreatePage(viewModelType);
        var currentNavigationPage = GetCurrentPage();

        if (currentNavigationPage != null)
        {
            await currentNavigationPage.Navigation.PushModalAsync(page, animated);
        }
        else
        {
            throw new Exception("Current page is null.");
        }

        await (page.BindingContext as BaseViewModel).InitializeAsync(parameter);
    }
}

As you may see there is a BaseViewModel - abstract base class for all the ViewModels where you can define methods like InitializeAsync that will get executed right after the navigation. And here is an example of navigation:

public class WelcomeViewModel : BaseViewModel
{
    public ICommand NewGameCmd { get; }
    public ICommand TopScoreCmd { get; }
    public ICommand AboutCmd { get; }

    public WelcomeViewModel(INavigationService navigation) : base(navigation)
    {
        NewGameCmd = new Command(async () => await Navigation.PushModalAsync<GameViewModel>());
        TopScoreCmd = new Command(async () => await navigation.PushModalAsync<TopScoreViewModel>());
        AboutCmd = new Command(async () => await navigation.PushModalAsync<AboutViewModel>());
    }
}

As you understand this approach is more complicated, harder to debug and might be confusing. However there are many advantages plus you actually don't have to implement it yourself since most of the MVVM frameworks support it out of the box. The code example that is demonstrated here is available on github.

There are plenty of good articles about ViewModel First Navigation approach and there is a free Enterprise Application Patterns using Xamarin.Forms eBook which is explaining this and many other interesting topics in detail.

You can use WhereNotIn in following way also:

ModelName::whereNotIn('book_price', [100,200])->get(['field_name1','field_name2']);

This will return collection of Record with specific fields

I understand that this question is old, but there is a good solution for it in HTML5. You can wrap it all in a <figure></figure> tag. The code would look something like this:

<div id="wrapper">
<figure>

<a href="mailto:[email protected]">
<img id="fblogo" border="0" alt="Mail" src="http://olympiahaacht.be/wp- 
content/uploads/2012/07/email-icon-e1343123697991.jpg"/>
</a>

<a href="https://www.facebook.com/OlympiaHaacht" target="_blank">
<img id="fblogo" border="0" alt="Facebook" src="http://olympiahaacht.be/wp- 
content/uploads/2012/04/FacebookButtonRevised-e1334605872360.jpg"/>
</a>

</figure>
</div>

and the CSS:

#wrapper{
 text-align:center;
}

you can set Focus to a specific Cell by setting Selected property to true

dataGridView1.Rows[rowindex].Cells[columnindex].Selected = true;

to avoid Multiple Selection just set

dataGridView1.MultiSelect = false;

// Another way, that does not rearrange the original Array 
// and spends a little less time handling duplicates.

function uniqueSort(arr, sortby){
    var A1= arr.slice();
    A1= typeof sortby== 'function'? A1.sort(sortby): A1.sort();

    var last= A1.shift(), next, A2= [last];
    while(A1.length){
        next= A1.shift();
        while(next=== last) next= A1.shift();
        if(next!=undefined){
            A2[A2.length]= next;
            last= next;
        }
    }
    return A2;
}
var myData= ['237','124','255','124','366','255','100','1000'];
uniqueSort(myData,function(a,b){return a-b})

// the ordinary sort() returns the same array as the number sort here,
// but some strings of digits do not sort so nicely numerical.

The globals() function returns a dictionary, where keys are names of objects you can name (and values, by the way, are ids of these objects) The exec() function takes a string and executes it as if you just type it in a python console. So, the code is

for i in list(globals().keys()):
    if(i[0] != '_'):
        exec('del {}'.format(i))

You can use df.isnull().sum(). It shows all columns and the total NaNs of each feature.

I experienced this exception using a SSL/TLS server Socket library on java 8. Updating the jdk to 14 (and also the VM to 14) solved the issue.

See this. Your code would be something like the following:

from django.db.models import Max
# Generates a "SELECT MAX..." query
Argument.objects.aggregate(Max('rating')) # {'rating__max': 5}

You can also use this on existing querysets:

from django.db.models import Max
args = Argument.objects.filter(name='foo') # or whatever arbitrary queryset
args.aggregate(Max('rating')) # {'rating__max': 5}

If you need the model instance that contains this max value, then the code you posted is probably the best way to do it:

arg = args.order_by('-rating')[0]

Note that this will error if the queryset is empty, i.e. if no arguments match the query (because the [0] part will raise an IndexError). If you want to avoid that behavior and instead simply return None in that case, use .first():

arg = args.order_by('-rating').first() # may return None

In the below mentioned link, ChromeDriver.exe for Windows 32 bit exist.

http://chromedriver.storage.googleapis.com/index.html?path=2.24/

It is working for me in Win7 64 bit.

add $row = mysql_fetch_object($result); after your mysql_query();

your html <img src="<?php echo $row->dvdimage; ?>" width="175" height="200" />

Once you have put the values into the JSONObject then put the JSONObject into the JSONArray staright after.

Something like this maybe:

jsonObj.put("value1", 1);
jsonObj.put("value2", 900);
jsonObj.put("value3", 1368349);
jsonArray.put(jsonObj);

Then create new JSONObject, put the other values into it and add it to the JSONArray:

jsonObj.put("value1", 2);
jsonObj.put("value2", 1900);
jsonObj.put("value3", 136856);
jsonArray.put(jsonObj);

You need to modify the Mapping Template

in Bitbucket go to branches in left hand side menu.

1. Select your branch you want to delete.
2. Go to action column, click on three dots (...) and select delete.

You can use a BinaryWriter object.

protected bool SaveData(string FileName, byte[] Data)
{
    BinaryWriter Writer = null;
    string Name = @"C:\temp\yourfile.name";

    try
    {
        // Create a new stream to write to the file
        Writer = new BinaryWriter(File.OpenWrite(Name));

        // Writer raw data                
        Writer.Write(Data);
        Writer.Flush();
        Writer.Close();
    }
    catch 
    {
        //...
        return false;
    }

    return true;
}

Edit: Oops, forgot the finally part... lets say it is left as an exercise for the reader ;-)

You override __hash__ if you want special hash-semantics, and __cmp__ or __eq__ in order to make your class usable as a key. Objects who compare equal need to have the same hash value.

Python expects __hash__ to return an integer, returning Banana() is not recommended :)

User defined classes have __hash__ by default that calls id(self), as you noted.

There is some extra tips from the documentation.:

Classes which inherit a __hash__() method from a parent class but change the meaning of __cmp__() or __eq__() such that the hash value returned is no longer appropriate (e.g. by switching to a value-based concept of equality instead of the default identity based equality) can explicitly flag themselves as being unhashable by setting __hash__ = None in the class definition. Doing so means that not only will instances of the class raise an appropriate TypeError when a program attempts to retrieve their hash value, but they will also be correctly identified as unhashable when checking isinstance(obj, collections.Hashable) (unlike classes which define their own __hash__() to explicitly raise TypeError).

Everyone else has explained why throwing destructors are terrible... what can you do about it? If you're doing an operation that may fail, create a separate public method that performs cleanup and can throw arbitrary exceptions. In most cases, users will ignore that. If users want to monitor the success/failure of the cleanup, they can simply call the explicit cleanup routine.

For example:

class TempFile {
public:
    TempFile(); // throws if the file couldn't be created
    ~TempFile() throw(); // does nothing if close() was already called; never throws
    void close(); // throws if the file couldn't be deleted (e.g. file is open by another process)
    // the rest of the class omitted...
};

Depending on your needs, this function will calculate the difference between the 2 days, and return a result in days decimal.

// This one returns a signed decimal. The sign indicates past or future.

this.getDateDiff = function(date1, date2) {
    return (date1.getTime() - date2.getTime()) / (1000 * 60 * 60 * 24);
}

// This one always returns a positive decimal. (Suggested by Koen below)

this.getDateDiff = function(date1, date2) {
    return Math.abs((date1.getTime() - date2.getTime()) / (1000 * 60 * 60 * 24));
}

In the interest of completeness, for people looking for a more modern solution, in Oracle 12c there are some new features including better paging and top handling.

Paging

The paging looks like this:

SELECT *
FROM user
ORDER BY first_name
OFFSET 5 ROWS FETCH NEXT 10 ROWS ONLY;

Top N Records

Getting the top records looks like this:

SELECT *
FROM user
ORDER BY first_name
FETCH FIRST 5 ROWS ONLY

Notice how both the above query examples have ORDER BY clauses. The new commands respect these and are run on the sorted data.

I couldn't find a good Oracle reference page for FETCH or OFFSET but this page has a great overview of these new features.

Performance

As @wweicker points out in the comments below, performance is an issue with the new syntax in 12c. I didn't have a copy of 18c to test if Oracle has since improved it.

Interestingly enough, my actual results were returned slightly quicker the first time I ran the queries on my table (113 million+ rows) for the new method:

• New method: 0.013 seconds.
• Old method: 0.107 seconds.

However, as @wweicker mentioned, the explain plan looks much worse for the new method:

• New method cost: 300,110
• Old method cost: 30

The new syntax caused a full scan of the index on my column, which was the entire cost. Chances are, things get much worse when limiting on unindexed data.

Let's have a look when including a single unindexed column on the previous dataset:

• New method time/cost: 189.55 seconds/998,908
• Old method time/cost: 1.973 seconds/256

Summary: use with caution until Oracle improves this handling. If you have an index to work with, perhaps you can get away with using the new method.

Hopefully I'll have a copy of 18c to play with soon and can update

Regarding conventions in C#. Let's say you're reading a cell that contains a date, e.g. 2014-10-22.

When using:

.Text, you'll get the formatted representation of the date, as seen in the workbook on-screen:
2014-10-22. This property's type is always string but may not always return a satisfactory result.

.Value, the compiler attempts to convert the date into a DateTime object: {2014-10-22 00:00:00} Most probably only useful when reading dates.

.Value2, gives you the real, underlying value of the cell. In the case for dates, it's a date serial: 41934. This property can have a different type depending on the contents of the cell. For date serials though, the type is double.

So you can retrieve and store the value of a cell in either dynamic, var or object but note that the value will always have some sort of innate type that you will have to act upon.

dynamic x = ws.get_Range("A1").Value2;
object  y = ws.get_Range("A1").Value2;
var     z = ws.get_Range("A1").Value2;
double  d = ws.get_Range("A1").Value2;      // Value of a serial is always a double

NOTE: This won't work in IE

var ob = {
    p: "ob.p"
}

var p = "window.p";

setTimeout(function(){
    console.log(this.p); // will print "window.p"
},1000); 

setTimeout(function(){
    console.log(this.p); // will print "ob.p"
}.bind(ob),1000);

Here's the FIDDLE

Same code as yours but it will work on dynamically created elements.

$(document).on('click', '.deletelanguage', function () {
    alert("success");
    $('#LangTable').append(' <br>------------<br> <a class="deletelanguage">Now my class is deletelanguage. click me to test it is not working.</a>');
});

Any component added to the GridLayout will be resized to the same size as the largest component added. If you want a component to remain at its preferred size, then wrap that component in a JPanel and then the panel will be resized:

JPanel displayPanel = new JPanel(new GridLayout(4, 2)); 
JTextField titleText = new JTextField("title"); 
JPanel wrapper = new JPanel( new FlowLayout(0, 0, FlowLayout.LEADING) );
wrapper.add( titleText );
displayPanel.add(wrapper); 
//displayPanel.add(titleText); 

You need to use Range and Value functions.
Range would be the cell where you want the text you want
Value would be the text that you want in that Cell

Range("A1").Value="whatever text"

Another option would be to run the batch file as a service, and set the startup of the service to "Automatic" or "Automatic (Delayed Start)". Check this question for more information on how to do it, personally I like NSSM the most.

The above answers really helped, but only delivered part of the solution. The major issue is that as soon as you remove the Default value attribute, the constraint on the column in database won't be removed. So previous default value will still stay in the database.

Here is a full solution to the problem, including removal of SQL constraints on attribute removal. I am also re-using .NET Framework's native DefaultValue attribute.

Usage

[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
[DefaultValue("getutcdate()")]
public DateTime CreatedOn { get; set; }

For this to work you need to update IdentityModels.cs and Configuration.cs files

IdentityModels.cs file

Add/update this method in your ApplicationDbContext class

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
            base.OnModelCreating(modelBuilder);
            var convention = new AttributeToColumnAnnotationConvention<DefaultValueAttribute, string>("SqlDefaultValue", (p, attributes) => attributes.SingleOrDefault().Value.ToString());
            modelBuilder.Conventions.Add(convention);
}

Configuration.cs file

Update your Configuration class constructor by registering custom Sql generator, like this:

internal sealed class Configuration : DbMigrationsConfiguration<ApplicationDbContext>
{
    public Configuration()
    {
        // DefaultValue Sql Generator
        SetSqlGenerator("System.Data.SqlClient", new DefaultValueSqlServerMigrationSqlGenerator());
    }
}

Next, add custom Sql generator class (you can add it to the Configuration.cs file or a separate file)

internal class DefaultValueSqlServerMigrationSqlGenerator : SqlServerMigrationSqlGenerator
{
    private int dropConstraintCount;

    protected override void Generate(AddColumnOperation addColumnOperation)
    {
        SetAnnotatedColumn(addColumnOperation.Column, addColumnOperation.Table);
        base.Generate(addColumnOperation);
    }

    protected override void Generate(AlterColumnOperation alterColumnOperation)
    {
        SetAnnotatedColumn(alterColumnOperation.Column, alterColumnOperation.Table);
        base.Generate(alterColumnOperation);
    }

    protected override void Generate(CreateTableOperation createTableOperation)
    {
        SetAnnotatedColumns(createTableOperation.Columns, createTableOperation.Name);
        base.Generate(createTableOperation);
    }

    protected override void Generate(AlterTableOperation alterTableOperation)
    {
        SetAnnotatedColumns(alterTableOperation.Columns, alterTableOperation.Name);
        base.Generate(alterTableOperation);
    }

    private void SetAnnotatedColumn(ColumnModel column, string tableName)
    {
        if (column.Annotations.TryGetValue("SqlDefaultValue", out var values))
        {
            if (values.NewValue == null)
            {
                column.DefaultValueSql = null;
                using var writer = Writer();

                // Drop Constraint
                writer.WriteLine(GetSqlDropConstraintQuery(tableName, column.Name));
                Statement(writer);
            }
            else
            {
                column.DefaultValueSql = (string)values.NewValue;
            }
        }
    }

    private void SetAnnotatedColumns(IEnumerable<ColumnModel> columns, string tableName)
    {
        foreach (var column in columns)
        {
            SetAnnotatedColumn(column, tableName);
        }
    }

    private string GetSqlDropConstraintQuery(string tableName, string columnName)
    {
        var tableNameSplitByDot = tableName.Split('.');
        var tableSchema = tableNameSplitByDot[0];
        var tablePureName = tableNameSplitByDot[1];

        var str = $@"DECLARE @var{dropConstraintCount} nvarchar(128)
SELECT @var{dropConstraintCount} = name
FROM sys.default_constraints
WHERE parent_object_id = object_id(N'{tableSchema}.[{tablePureName}]')
AND col_name(parent_object_id, parent_column_id) = '{columnName}';
IF @var{dropConstraintCount} IS NOT NULL
EXECUTE('ALTER TABLE {tableSchema}.[{tablePureName}] DROP CONSTRAINT [' + @var{dropConstraintCount} + ']')";

        dropConstraintCount++;
        return str;
    }
}

May I expand on the question and ask if Git work well on MacOS?

Reply to Comments: Thanks for the news, I'd been looking forward to trying it out. I'll install it at home on my Mac.

Threading Model in UI

Please read the Threading Model in UI applications (old VB link is here) in order to understand basic concepts. The link navigates to page that describes the WPF threading model. However, Windows Forms utilizes the same idea.

The UI Thread

• There is only one thread (UI thread), that is allowed to access System.Windows.Forms.Control and its subclasses members.
• Attempt to access member of System.Windows.Forms.Control from different thread than UI thread will cause cross-thread exception.
• Since there is only one thread, all UI operations are queued as work items into that thread:

• If there is no work for UI thread, then there are idle gaps that can be used by a not-UI related computing.
• In order to use mentioned gaps use System.Windows.Forms.Control.Invoke or System.Windows.Forms.Control.BeginInvoke methods:

BeginInvoke and Invoke methods

• The computing overhead of method being invoked should be small as well as computing overhead of event handler methods because the UI thread is used there - the same that is responsible for handling user input. Regardless if this is System.Windows.Forms.Control.Invoke or System.Windows.Forms.Control.BeginInvoke.
• To perform computing expensive operation always use separate thread. Since .NET 2.0 BackgroundWorker is dedicated to performing computing expensive operations in Windows Forms. However in new solutions you should use the async-await pattern as described here.
• Use System.Windows.Forms.Control.Invoke or System.Windows.Forms.Control.BeginInvoke methods only to update a user interface. If you use them for heavy computations, your application will block:

Invoke

• System.Windows.Forms.Control.Invoke causes separate thread to wait till invoked method is completed:

BeginInvoke

• System.Windows.Forms.Control.BeginInvoke doesn't cause the separate thread to wait till invoked method is completed:

Code solution

Read answers on question How to update the GUI from another thread in C#?. For C# 5.0 and .NET 4.5 the recommended solution is here.

Android comes with a built-in YesNoPreference class that does exactly what you want (a confirm dialog with yes and no options). See the official source code here.

Unfortunately, it is in the com.android.internal.preference package, which means it is a part of Android's private APIs and you cannot access it from your application (private API classes are subject to change without notice, hence the reason why Google does not let you access them).

Solution: just re-create the class in your application's package by copy/pasting the official source code from the link I provided. I've tried this, and it works fine (there's no reason why it shouldn't).

You can then add it to your preferences.xml like any other Preference. Example:

<com.example.myapp.YesNoPreference
    android:dialogMessage="Are you sure you want to revert all settings to their default values?"
    android:key="com.example.myapp.pref_reset_settings_key"
    android:summary="Revert all settings to their default values."
    android:title="Reset Settings" />

Which looks like this:

 System.out.println(System.getProperty("java.vendor"));
 System.out.println(System.getProperty("java.vendor.url"));
 System.out.println(System.getProperty("java.version"));

"Extended WPF Toolkit" now provides a richtextbox with the Text property.

You can get or set the text in different formats (XAML, RTF and plaintext).

Here is the link: Extended WPF Toolkit RichTextBox

To add to craig_h's comment above (I currently don't have enough rep to add this as a comment to his answer, sorry), if your primary key is not an integer, you'll also want to tell your model what data type it is, by setting keyType at the top of the model definition.

public $keyType = 'string'

Eloquent understands any of the types defined in the castAttribute() function, which as of Laravel 5.4 are: int, float, string, bool, object, array, collection, date and timestamp.

This will ensure that your primary key is correctly cast into the equivalent PHP data type.

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

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

Try this:

first, *rest = ex.split(/, /)

Now first will be the first value, rest will be the rest of the array.

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

$ ip route show default | awk '/default/ {print $5}'

return: eth0 (my online interface)

$ cat /sys/class/net/$(ip route show default | awk '/default/ {print $5}')/address

return: ec:a8:6b:bd:55:05 (macaddress of the eth0, my online interface)

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

As per my knowledge Inline sytle comes first so css class should not work.

Use Jquery as

$(document).ready(function(){

   $("#demoFour li").css("display","inline");
  });

You can also try 

#demoFour li { display:inline !important;}

I determined that this problem was a corrupt connection manager by identifying the specific connection that was failing. I'm working in SQL Server 2016 and I have created the SSISDB catalog and I am deploying my projects there.

Here's the short answer. Delete the connection manager and then re-create it with the same name. Make sure the packages using that connection are still wired up correctly and you should be good to go. If you're not sure how to do that, I've included the detailed procedure below.

To identify the corrupt connection, I did the following. In SSMS, I opened the Integration Services Catalogs folder, then the SSISDB folder, then the folder for my solution, and on down until I found my list of packages for that project.

By right clicking the package that failed, going to reports>standard reports>all executions, selecting the last execution, and viewing the "All Messages" report I was able to isolate which connection was failing. In my case, the connection manager to my destination. I simply deleted the connection manager and then recreated a new connection manager with the same name.

Subsequently, I went into my package, opened the data flow, found that some of my destinations had lit up with the red X. I opened the destination, re-selected the correct connection name, re-selected the target table, and checked the mappings were still correct. I had six destinations and only three had the red X but I clicked all of them and made sure they were still configured correctly.

I use very minimal, one page class implementation inspired by code from this blog post:

#import <mach/mach_time.h>

@interface DBGStopwatch : NSObject

+ (void)start:(NSString *)name;
+ (void)stop:(NSString *)name;

@end

@implementation DBGStopwatch

+ (NSMutableDictionary *)watches {
    static NSMutableDictionary *Watches = nil;
    static dispatch_once_t OnceToken;
    dispatch_once(&OnceToken, ^{
        Watches = @{}.mutableCopy;
    });
    return Watches;
}

+ (double)secondsFromMachTime:(uint64_t)time {
    mach_timebase_info_data_t timebase;
    mach_timebase_info(&timebase);
    return (double)time * (double)timebase.numer /
        (double)timebase.denom / 1e9;
}

+ (void)start:(NSString *)name {
    uint64_t begin = mach_absolute_time();
    self.watches[name] = @(begin);
}

+ (void)stop:(NSString *)name {
    uint64_t end = mach_absolute_time();
    uint64_t begin = [self.watches[name] unsignedLongLongValue];
    DDLogInfo(@"Time taken for %@ %g s",
              name, [self secondsFromMachTime:(end - begin)]);
    [self.watches removeObjectForKey:name];
}

@end

The usage of it is very simple:

• just call [DBGStopwatch start:@"slow-operation"]; at the beginning
• and then [DBGStopwatch stop:@"slow-operation"]; after the finish, to get the time

Try df.mean(axis=0) , axis=0 argument calculates the column wise mean of the dataframe so the result will be axis=1 is row wise mean so you are getting multiple values.

You need to run Set-ExecutionPolicy:

Set-ExecutionPolicy Unrestricted <-- Will allow unsigned PowerShell scripts to run.

Set-ExecutionPolicy Restricted <-- Will not allow unsigned PowerShell scripts to run.

Set-ExecutionPolicy RemoteSigned <-- Will allow only remotely signed PowerShell scripts to run.

I have just dealt with similar issue. In my case the default site asp.net version was 1.1 while i was trying to start up a 2.0 web app. The error was pretty trivial, but it was not immediately clear why the custom errors would not go away, and runtime never wrote to event log. Obvious fix was to match the version in Asp.Net tab of IIS.

while ((inputLine = in.readLine()) != null)
    System.out.println(inputLine);

I ran into this error because I was trying to pass in a date from localStorage. Passing the date into a new Date object, and then calling .toISOString() did the trick for me:

const dateFromStorage = localStorage.getItem('someDate');
const date = new Date(dateFromStorage);
const momentDate = moment(date.toISOString());

This suppressed any warnings in the console.

I'v solved this error by setting the correct path variables

Heres what I do for Bootstrap 3/4

Use container-fluid instead of container.

Add this to my CSS

@media (min-width: 1400px) {
    .container-fluid{
        max-width: 1400px;
    }   
}

This removes margins below 1400px width screen

For someone who wants to convert int to string in specific digits, the below method is recommended.

I hate pasting URLs but https://docs.oracle.com/javase/10/docs/api/java/lang/String.html is essential for you to read and understand if you're in java-land.

I think it's better work with individual "views", Im trying to move from PHP to MVC4, its really hard but im on the right way...

Answering your question, if you'll work individual pages, just edit the _ViewStart.cshtml

@{
  Layout = null;
}

Another tip if you're getting some issues with CSS path...

Put "../" before of the url

This are the 2 problems that i get today, and I resolve in that way!

You might want to look into Lex/Yacc (or Flex/Bison, whatever you want to call them). Flex is a lexical analyzer, which will parse and identify the semantic components ("tokens") of your language, and Bison will be used to define what happens when each token is parsed. This could be, but is definitely not limited to, printing out C code, for a compiler that would compile to C, or dynamically running the instructions.

This FAQ should help you, and this tutorial looks quite useful.

The print function in python adds itself \n

You could use

import sys
sys.stdout.write(a)

instead

with jQuery its even easier and works on Chrome as well

$('#your-button').on('click', function(){
       $('<a href="https://www.some-page.com" target="blank"></a>')[0].click();    
})

Vartec's answer doesn't read all lines, so I made a version that did:

def run_command(command):
    p = subprocess.Popen(command,
                         stdout=subprocess.PIPE,
                         stderr=subprocess.STDOUT)
    return iter(p.stdout.readline, b'')

Usage is the same as the accepted answer:

command = 'mysqladmin create test -uroot -pmysqladmin12'.split()
for line in run_command(command):
    print(line)

Generic Object Oriented Solution

For people like me that use frameworks like angular that don't allow manipulating DOM directly, I created a function that takes a string and returns an array of url/plainText objects that can be used to create any UI representation that you want.

URL regex

For URL matching I used (slightly adapted) h0mayun regex: /(?:(?:https?:\/\/)|(?:www\.))[^\s]+/g

My function also drops punctuation characters from the end of a URL like . and , that I believe more often will be actual punctuation than a legit URL ending (but it could be! This is not rigorous science as other answers explain well) For that I apply the following regex onto matched URLs /^(.+?)([.,?!'"]*)$/.

Typescript code

    export function urlMatcherInText(inputString: string): UrlMatcherResult[] {
        if (! inputString) return [];

        const results: UrlMatcherResult[] = [];

        function addText(text: string) {
            if (! text) return;

            const result = new UrlMatcherResult();
            result.type = 'text';
            result.value = text;
            results.push(result);
        }

        function addUrl(url: string) {
            if (! url) return;

            const result = new UrlMatcherResult();
            result.type = 'url';
            result.value = url;
            results.push(result);
        }

        const findUrlRegex = /(?:(?:https?:\/\/)|(?:www\.))[^\s]+/g;
        const cleanUrlRegex = /^(.+?)([.,?!'"]*)$/;

        let match: RegExpExecArray;
        let indexOfStartOfString = 0;

        do {
            match = findUrlRegex.exec(inputString);

            if (match) {
                const text = inputString.substr(indexOfStartOfString, match.index - indexOfStartOfString);
                addText(text);

                var dirtyUrl = match[0];
                var urlDirtyMatch = cleanUrlRegex.exec(dirtyUrl);
                addUrl(urlDirtyMatch[1]);
                addText(urlDirtyMatch[2]);

                indexOfStartOfString = match.index + dirtyUrl.length;
            }
        }
        while (match);

        const remainingText = inputString.substr(indexOfStartOfString, inputString.length - indexOfStartOfString);
        addText(remainingText);

        return results;
    }

    export class UrlMatcherResult {
        public type: 'url' | 'text'
        public value: string
    }

To print your context ,you can write code like this :

FILE *fp;
char *of;
sprintf(of,"%s%s",text1,text2);
fp=fopen(of,'w');
fprintf(fp,"your print line");

With LD_PRELOAD you can give libraries precedence.

For example you can write a library which implement malloc and free. And by loading these with LD_PRELOAD your malloc and free will be executed rather than the standard ones.

this is server configuration, set up config.addAllowedHeader("*"); in the CorsConfiguration.

There are so many answers here, but if you're trying to change the jks password on a Mac in Android Studio. Here are the easiest steps I could find

1) Open Terminal and cd to where your .jks is located

2) keytool -storepasswd -new NEWPASSWORD -keystore YOURKEYSTORE.jks

3) enter your current password

I had the same problem and it was related to the .gitattributes file. However the file type that caused the problem was not specified in the .gitattributes.

If you build an APK for a target screen resolution like HDPI, the Android asset packageing tool,AAPT,can strip out the drawables for other resolution you don’t need.But if it’s in the mipmap folder,then these assets will stay in the APK, regardless of the target resolution.

I did some searching on the web, and this are some ways that I found:

The easiest way is using curve without predefined function

curve(x^2, from=1, to=50, , xlab="x", ylab="y")

You can also use curve when you have a predfined function

eq = function(x){x*x}
curve(eq, from=1, to=50, xlab="x", ylab="y")

If you want to use ggplot,

library("ggplot2")
eq = function(x){x*x}
ggplot(data.frame(x=c(1, 50)), aes(x=x)) + 
  stat_function(fun=eq)

with your toolbar you can solve that problem. use setTitle method.

 Toolbar   mToolbar = (Toolbar) findViewById(R.id.toolbar);
  mToolbar.setTitle("");
  setSupportActionBar(mToolbar);

super easy :)

If the check box's ID "Delete" then for the "onclick" event of the submit button the javascript function can be as follows:

html:
<input type="checkbox" name="Delete" value="Delete" id="Delete"></td>
<input type="button" value="Delete" name="delBtn" id="delBtn" onclick="deleteData()">

script:
<script type="text/Javascript">
    function deleteData() {
        if(!document.getElementById('Delete').checked){
            alert('Checkbox not checked');
            return false;
        }
</script>

Your json string is wrapped within square brackets ([]), hence it is interpreted as array instead of single RetrieveMultipleResponse object. Therefore, you need to deserialize it to type collection of RetrieveMultipleResponse, for example :

var objResponse1 = 
    JsonConvert.DeserializeObject<List<RetrieveMultipleResponse>>(JsonStr);

The thing I'd found confusing about -prune is that it's an action (like -print), not a test (like -name). It alters the "to-do" list, but always returns true.

The general pattern for using -prune is this:

find [path] [conditions to prune] -prune -o \
            [your usual conditions] [actions to perform]

You pretty much always want the -o (logical OR) immediately after -prune, because that first part of the test (up to and including -prune) will return false for the stuff you actually want (ie: the stuff you don't want to prune out).

Here's an example:

find . -name .snapshot -prune -o -name '*.foo' -print

This will find the "*.foo" files that aren't under ".snapshot" directories. In this example, -name .snapshot makes up the [conditions to prune], and -name '*.foo' -print is [your usual conditions] and [actions to perform].

Important notes:

1. If all you want to do is print the results you might be used to leaving out the -print action. You generally don't want to do that when using -prune.

   The default behavior of find is to "and" the entire expression with the -print action if there are no actions other than -prune (ironically) at the end. That means that writing this:

    find . -name .snapshot -prune -o -name '*.foo'              # DON'T DO THIS
   

   is equivalent to writing this:

    find . \( -name .snapshot -prune -o -name '*.foo' \) -print # DON'T DO THIS
   

   which means that it'll also print out the name of the directory you're pruning, which usually isn't what you want. Instead it's better to explicitly specify the -print action if that's what you want:

    find . -name .snapshot -prune -o -name '*.foo' -print       # DO THIS
   

2. If your "usual condition" happens to match files that also match your prune condition, those files will not be included in the output. The way to fix this is to add a -type d predicate to your prune condition.

   For example, suppose we wanted to prune out any directory that started with .git (this is admittedly somewhat contrived -- normally you only need to remove the thing named exactly .git), but other than that wanted to see all files, including files like .gitignore. You might try this:

   find . -name '.git*' -prune -o -type f -print               # DON'T DO THIS
   

   This would not include .gitignore in the output. Here's the fixed version:

   find . -name '.git*' -type d -prune -o -type f -print       # DO THIS
   

Extra tip: if you're using the GNU version of find, the texinfo page for find has a more detailed explanation than its manpage (as is true for most GNU utilities).

another way to access a column by number is to use a mapping dictionary where the key is the column name and the value is the column number

dates = pd.date_range('1/1/2000', periods=8)

df = pd.DataFrame(np.random.randn(8, 4),
   index=dates, columns=['A', 'B', 'C', 'D'])
print(df)
dct={'A':0,'B':1,'C':2,'D':3}
columns=df.columns

print(df.iloc[:,dct['D']])

Answer based on JQuery < 3

$('#iframeid').load(function(){
    alert('frame has (re)loaded');
});

As mentioned by subharb, as from JQuery 3.0 this needs to be changed to:

$('#iframe').on('load', function() {
    alert('frame has (re)loaded ');
});

If you take Erics answer a little further you can actually create a pretty decent implementation of abstract classes, with full support for polymorphism and the ability to call implemented methods from the base class. Let's start with the code:

/**
 * The interface defines all abstract methods and extends the concrete base class
 */
interface IAnimal extends Animal {
    speak() : void;
}

/**
 * The abstract base class only defines concrete methods & properties.
 */
class Animal {

    private _impl : IAnimal;

    public name : string;

    /**
     * Here comes the clever part: by letting the constructor take an 
     * implementation of IAnimal as argument Animal cannot be instantiated
     * without a valid implementation of the abstract methods.
     */
    constructor(impl : IAnimal, name : string) {
        this.name = name;
        this._impl = impl;

        // The `impl` object can be used to delegate functionality to the
        // implementation class.
        console.log(this.name + " is born!");
        this._impl.speak();
    }
}

class Dog extends Animal implements IAnimal {
    constructor(name : string) {
        // The child class simply passes itself to Animal
        super(this, name);
    }

    public speak() {
        console.log("bark");
    }
}

var dog = new Dog("Bob");
dog.speak(); //logs "bark"
console.log(dog instanceof Dog); //true
console.log(dog instanceof Animal); //true
console.log(dog.name); //"Bob"

Since the Animal class requires an implementation of IAnimal it's impossible to construct an object of type Animal without having a valid implementation of the abstract methods. Note that for polymorphism to work you need to pass around instances of IAnimal, not Animal. E.g.:

//This works
function letTheIAnimalSpeak(animal: IAnimal) {
    console.log(animal.name + " says:");
    animal.speak();
}
//This doesn't ("The property 'speak' does not exist on value of type 'Animal')
function letTheAnimalSpeak(animal: Animal) {
    console.log(animal.name + " says:");
    animal.speak();
}

The main difference here with Erics answer is that the "abstract" base class requires an implementation of the interface, and thus cannot be instantiated on it's own.

Your second way is correct.

def foo(opts: dict = {}):
    pass

print(foo.__annotations__)

this outputs

{'opts': <class 'dict'>}

It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.

I strongly advise against using mutable keyword arguments. More information here.

I think you are very confused about what is occurring.

In Python, everything is an object:

• [] (a list) is an object
• 'abcde' (a string) is an object
• 1 (an integer) is an object
• MyClass() (an instance) is an object
• MyClass (a class) is also an object
• list (a type--much like a class) is also an object

They are all "values" in the sense that they are a thing and not a name which refers to a thing. (Variables are names which refer to values.) A value is not something different from an object in Python.

When you call a class object (like MyClass() or list()), it returns an instance of that class. (list is really a type and not a class, but I am simplifying a bit here.)

When you print an object (i.e. get a string representation of an object), that object's __str__ or __repr__ magic method is called and the returned value printed.

For example:

>>> class MyClass(object):
...     def __str__(self):
...             return "MyClass([])"
...     def __repr__(self):
...             return "I am an instance of MyClass at address "+hex(id(self))
... 
>>> m = MyClass()
>>> print m
MyClass([])
>>> m
I am an instance of MyClass at address 0x108ed5a10
>>> 

So what you are asking for, "I need that MyClass return a list, like list(), not the instance info," does not make any sense. list() returns a list instance. MyClass() returns a MyClass instance. If you want a list instance, just get a list instance. If the issue instead is what do these objects look like when you print them or look at them in the console, then create a __str__ and __repr__ method which represents them as you want them to be represented.

Update for new question about equality

Once again, __str__ and __repr__ are only for printing, and do not affect the object in any other way. Just because two objects have the same __repr__ value does not mean they are equal!

MyClass() != MyClass() because your class does not define how these would be equal, so it falls back to the default behavior (of the object type), which is that objects are only equal to themselves:

>>> m = MyClass()
>>> m1 = m
>>> m2 = m
>>> m1 == m2
True
>>> m3 = MyClass()
>>> m1 == m3
False

If you want to change this, use one of the comparison magic methods

For example, you can have an object that is equal to everything:

>>> class MyClass(object):
...     def __eq__(self, other):
...             return True
... 
>>> m1 = MyClass()
>>> m2 = MyClass()
>>> m1 == m2
True
>>> m1 == m1
True
>>> m1 == 1
True
>>> m1 == None
True
>>> m1 == []
True

I think you should do two things:

1. Take a look at this guide to magic method use in Python.

2. Justify why you are not subclassing list if what you want is very list-like. If subclassing is not appropriate, you can delegate to a wrapped list instance instead:

   class MyClass(object):
       def __init__(self):
           self._list = []
       def __getattr__(self, name):
           return getattr(self._list, name)
   
       # __repr__ and __str__ methods are automatically created
       # for every class, so if we want to delegate these we must
       # do so explicitly
       def __repr__(self):
           return "MyClass(%s)" % repr(self._list)
       def __str__(self):
           return "MyClass(%s)" % str(self._list)
   

   This will now act like a list without being a list (i.e., without subclassing list).

   >>> c = MyClass()
   >>> c.append(1)
   >>> c
   MyClass([1])
   

Just:

sudo rpm -Uvh https://archives.fedoraproject.org/pub/archive/epel/5/i386/epel-release-5-4.noarch.rpm
sudo yum install git-core

You could use the PHP in_array function

if( in_array( "bla" ,$yourarray ) )
{
    echo "has bla";
}

To resolve this issue, Go to your Project properties -> Java compiler -> Select compiler compliance level to 1.6-> Apply.

When you define your function using this syntax:

def someFunc(*args):
    for x in args
        print x

You're telling it that you expect a variable number of arguments. If you want to pass in a List (Array from other languages) you'd do something like this:

def someFunc(myList = [], *args):
    for x in myList:
        print x

Then you can call it with this:

items = [1,2,3,4,5]

someFunc(items)

You need to define named arguments before variable arguments, and variable arguments before keyword arguments. You can also have this:

def someFunc(arg1, arg2, arg3, *args, **kwargs):
    for x in args
        print x

Which requires at least three arguments, and supports variable numbers of other arguments and keyword arguments.

Using the for-loop like you have, one way is this:

def altElement(a):
    b = []
    j = False
    for i in a:
        j = not j
        if j:
            b.append(i)

    print b

j just keeps switching between 0 and 1 to keep track of when to append an element to b.

!members.find()

I think now the best way to solve this issue is code above. It works since Groovy 1.8.1 http://docs.groovy-lang.org/docs/next/html/groovy-jdk/java/util/Collection.html#find(). Examples:

def lst1 = []
assert !lst1.find()

def lst2 = [null]
assert !lst2.find()

def lst3 = [null,2,null]
assert lst3.find()

def lst4 = [null,null,null]
assert !lst4.find()

def lst5 = [null, 0, 0.0, false, '', [], 42, 43]
assert lst5.find() == 42

def lst6 = null; 
assert !lst6.find()

Android WebView is just another render engine that render HTML contents downloaded from a HTTP server, much like Chrome or FireFox. I don't know the reason why you need get the rendered page (or screenshot) from WebView. For most of situation, this is not necessary. You can always get the raw HTML content from HTTP server directly.

There are already answers posted talking about getting the raw stream using HttpUrlConnection or HttpClient. Alternatively, there is a very handy library when dealing with HTML content parse/process on Android: JSoup, it provide very simple API to get HTML contents form HTTP server, and provide an abstract representation of HTML document to help us manage HTML parsing not only in a more OO style but also much easily:

// Single line of statement to get HTML document from HTTP server.
Document doc = Jsoup.connect("http://en.wikipedia.org/").get();

It is handy when, for example, you want to download HTML document first then add some custom css or javascript to it before passing it to WebView for rendering. Much more on their official web site, worth to check it out.

You can use the Google Docs PDF-viewing widget, if you don't mind having them host the "application" itself.

I had more suggestions, but stack overflow only lets me post one hyperlink as a new user, sorry.

Check this page out: http://matplotlib.org/examples/pylab_examples/subplots_demo.html

plt.subplots is similar. I think it's better since it's easier to set parameters of the figure. The first two arguments define the layout (in your case 1 row, 2 columns), and other parameters change features such as figure size:

import numpy as np
import matplotlib.pyplot as plt

x1 = np.linspace(0.0, 5.0)
x2 = np.linspace(0.0, 2.0)
y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
y2 = np.cos(2 * np.pi * x2)

fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(5, 3))
axes[0].plot(x1, y1)
axes[1].plot(x2, y2)
fig.tight_layout()

In C, you can use the built in qsort command:

int compare( const void* a, const void* b)
{
     int int_a = * ( (int*) a );
     int int_b = * ( (int*) b );

     if ( int_a == int_b ) return 0;
     else if ( int_a < int_b ) return -1;
     else return 1;
}

qsort( a, 6, sizeof(int), compare )

see: http://www.cplusplus.com/reference/clibrary/cstdlib/qsort/

To answer the second part of your question: an optimal (comparison based) sorting algorithm is one that runs with O(n log(n)) comparisons. There are several that have this property (including quick sort, merge sort, heap sort, etc.), but which one to use depends on your use case.

As a side note, you can sometime do better than O(n log(n)) if you know something about your data - see the wikipedia article on Radix Sort

class Countries < ActiveRecord::Base
    self.table_name = "cc"
end

In Rails 3.x this is the way to specify the table name.

// spawn: allocate and initialize (a simple function)
template<typename T>
T * spawn(size_t n, ...){
  T * arr = new T[n];
  va_list ap;
  va_start(ap, n);
  for (size_t i = 0; i < n; i++)
    T[i] = va_arg(ap,T);
  return arr;

Semantically, this looks and feels exactly like an n-argument function. Under the hood, you might unpack it one way or the other.

You have compiled your code with references to the correct math.h header file, but when you attempted to link it, you forgot the option to include the math library. As a result, you can compile your .o object files, but not build your executable.

As Paul has already mentioned add "-lm" to link with the math library in the step where you are attempting to generate your executable.

In the comment, linuxD asks:

Why for sin() in <math.h>, do we need -lm option explicitly; but, not for printf() in <stdio.h>?

Because both these functions are implemented as part of the "Single UNIX Specification". This history of this standard is interesting, and is known by many names (IEEE Std 1003.1, X/Open Portability Guide, POSIX, Spec 1170).

This standard, specifically separates out the "Standard C library" routines from the "Standard C Mathematical Library" routines (page 277). The pertinent passage is copied below:

Standard C Library

The Standard C library is automatically searched by cc to resolve external references. This library supports all of the interfaces of the Base System, as defined in Volume 1, except for the Math Routines.

Standard C Mathematical Library

This library supports the Base System math routines, as defined in Volume 1. The cc option -lm is used to search this library.

The reasoning behind this separation was influenced by a number of factors:

1. The UNIX wars led to increasing divergence from the original AT&T UNIX offering.
2. The number of UNIX platforms added difficulty in developing software for the operating system.
3. An attempt to define the lowest common denominator for software developers was launched, called 1988 POSIX.
4. Software developers programmed against the POSIX standard to provide their software on "POSIX compliant systems" in order to reach more platforms.
5. UNIX customers demanded "POSIX compliant" UNIX systems to run the software.

The pressures that fed into the decision to put -lm in a different library probably included, but are not limited to:

1. It seems like a good way to keep the size of libc down, as many applications don't use functions embedded in the math library.
2. It provides flexibility in math library implementation, where some math libraries rely on larger embedded lookup tables while others may rely on smaller lookup tables (computing solutions).
3. For truly size constrained applications, it permits reimplementations of the math library in a non-standard way (like pulling out just sin() and putting it in a custom built library.

In any case, it is now part of the standard to not be automatically included as part of the C language, and that's why you must add -lm.

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

For triggers in general, you need to use a cursor to handle inserts or updates of multiple rows. For example:

DECLARE @Attribute;
DECLARE @ParameterValue;
DECLARE mycursor CURSOR FOR SELECT Attribute, ParameterValue FROM inserted;
OPEN mycursor;
FETCH NEXT FROM mycursor into @Attribute, @ParameterValue;
WHILE @@FETCH_STATUS = 0
BEGIN

If @Attribute LIKE 'NoHist_%'
      Begin
          Return
      End

etc.

FETCH NEXT FROM mycursor into @Attribute, @ParameterValue;
END

Triggers, at least in SQL Server, are a big pain and I avoid using them at all.

For anyone who's looking to do this in 2018, I've got a much better and simpler solution then all the old stuff posted here. You can make a nice looking drag & drop box with just vanilla HTML, JavaScript and CSS.

(Only works in Chrome so far)

Let's start with the HTML.

<div>
<input type="file" name="file" id="file" class="file">
<span id="value"></span>
</div>

Then we'll get to the styling.

    .file {
        width: 400px;
        height: 50px;
        background: #171717;
        padding: 4px;
        border: 1px dashed #333;
        position: relative;
        cursor: pointer;
    }

    .file::before {
        content: '';
        position: absolute;
        background: #171717;
        font-size: 20px;
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
        width: 100%;
        height: 100%;
    }

    .file::after {
        content: 'Drag & Drop';
        position: absolute;
        color: #808080;
        font-size: 20px;
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
    }

After you've done this it already looks fine. But I imagine you'd like to see what file you actaully uploaded, so we're going to do some JavaScript. Remember that pfp-value span? That's where we'll print out the file name.

let file = document.getElementById('file');
file.addEventListener('change', function() {
    if(file && file.value) {
        let val = file.files[0].name;
        document.getElementById('value').innerHTML = "Selected" + val;
    }
});

And that's it.

This should work. getElementsByClassName returns an array Array-like object(see edit) of the elements matching the criteria.

var elements = document.getElementsByClassName("classname");

var myFunction = function() {
    var attribute = this.getAttribute("data-myattribute");
    alert(attribute);
};

for (var i = 0; i < elements.length; i++) {
    elements[i].addEventListener('click', myFunction, false);
}

jQuery does the looping part for you, which you need to do in plain JavaScript.

If you have ES6 support you can replace your last line with:

    Array.from(elements).forEach(function(element) {
      element.addEventListener('click', myFunction);
    });

Note: Older browsers (like IE6, IE7, IE8) don´t support getElementsByClassName and so they return undefined.

EDIT : Correction

getElementsByClassName doesnt return an array, but a HTMLCollection in most, or a NodeList in some browsers (Mozilla ref). Both of these types are Array-Like, (meaning that they have a length property and the objects can be accessed via their index), but are not strictly an Array or inherited from an Array. (meaning other methods that can be performed on an Array cannot be performed on these types)

Thanks to user @Nemo for pointing this out and having me dig in to fully understand.

If you are using PHP's password_hash() with the PASSWORD_DEFAULT algorithm to generate the bcrypt hash (which I would assume is a large percentage of people reading this question) be sure to keep in mind that in the future password_hash() might use a different algorithm as the default and this could therefore affect the length of the hash (but it may not necessarily be longer).

From the manual page:

Note that this constant is designed to change over time as new and stronger algorithms are added to PHP. For that reason, the length of the result from using this identifier can change over time. Therefore, it is recommended to store the result in a database column that can expand beyond 60 characters (255 characters would be a good choice).

Using bcrypt, even if you have 1 billion users (i.e. you're currently competing with facebook) to store 255 byte password hashes it would only ~255 GB of data - about the size of a smallish SSD hard drive. It is extremely unlikely that storing the password hash is going to be the bottleneck in your application. However in the off chance that storage space really is an issue for some reason, you can use PASSWORD_BCRYPT to force password_hash() to use bcrypt, even if that's not the default. Just be sure to stay informed about any vulnerabilities found in bcrypt and review the release notes every time a new PHP version is released. If the default algorithm is ever changed it would be good to review why and make an informed decision whether to use the new algorithm or not.

char a[2] defines an array of char's. a is a pointer to the memory at the beginning of the array and using == won't actually compare the contents of a with 'ab' because they aren't actually the same types, 'ab' is integer type. Also 'ab' should be "ab" otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.

Something that might be illustrative is looking at the typeid of 'ab':

#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
    int some_int =5;
    std::cout << typeid('ab').name() << std::endl;
    std::cout << typeid(some_int).name() << std::endl;
    return 0;
}

on my system this returns:

i
i

showing that 'ab' is actually evaluated as an int.

If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator == overloaded and will do a comparison check when called this way.

If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:

#include <iostream>
#include <string>
using namespace std;
int main(){
    string a;
    cout<<"enter ab ";
    cin>>a;
    if(a=="ab"){
         cout<<"correct";
    }
    return 0;
}

This one is due to:

if(a=='ab') , here, a is const char* type (ie : array of char)

'ab' is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.

Since char is a primitive type inherited from C, no operator == is defined.

the good code should be:

if(strcmp(a,"ab")==0) , then you'll compare a const char* to another const char* using strcmp.

An old question, but I also have two methods.

For a fixed (predefined) length:

    public static String fill(String text) {
        if (text.length() >= 10)
            return text;
        else
            return "0000000000".substring(text.length()) + text;
    }

For a variable length:

    public static String fill(String text, int size) {
        StringBuilder builder = new StringBuilder(text);
        while (builder.length() < size) {
            builder.append('0');
        }
        return builder.toString();
    }

In the following shell commands existing-dir is a directory whose contents match the tracked files in the repo-to-clone git repository.

# Clone just the repository's .git folder (excluding files as they are already in
# `existing-dir`) into an empty temporary directory
git clone --no-checkout repo-to-clone existing-dir/existing-dir.tmp # might want --no-hardlinks for cloning local repo

# Move the .git folder to the directory with the files.
# This makes `existing-dir` a git repo.
mv existing-dir/existing-dir.tmp/.git existing-dir/

# Delete the temporary directory
rmdir existing-dir/existing-dir.tmp
cd existing-dir

# git thinks all files are deleted, this reverts the state of the repo to HEAD.
# WARNING: any local changes to the files will be lost.
git reset --hard HEAD

This tiny java method will help you produce standard CSV text of a specific column.

public static String getStandardizedCsv(String columnText){

    //contains line feed ?
    boolean containsLineFeed = false;
    if(columnText.contains("\n")){
        containsLineFeed = true;
    }

    boolean containsCommas = false;
    if(columnText.contains(",")){
        containsCommas = true;
    }

    boolean containsDoubleQuotes = false;
    if(columnText.contains("\"")){
        containsDoubleQuotes = true;
    }

    columnText.replaceAll("\"", "\"\"");

    if(containsLineFeed || containsCommas || containsDoubleQuotes){
        columnText = "\"" + columnText + "\"";
    }

    return columnText;
}

class Node:
    def __init__(self, wordList=None adjacencyList=None):
        self.wordList = wordList or []
        self.adjacencyList = adjacencyList or []

FWIW, in case anyone revisits this question later, you might also check what you are handing to your onKeyPress handler function.

I ran into this error when I mistakenly passed onKeyPress(this) instead of onKeyPress(event).

Just something else to check.

I struggled with this as well but heres the solution. If you add " before and at the end of the csv string you are trying to display, it will consolidate them into 1 cell while honoring new line.

csvString += "\""+"Date Generated: \n" ; 
csvString += "Doctor: " + "\n"+"\"" + "\n";

Also, you may try the getUserMedia method (supported by Opera 12)

In my particular case -g -march=armv7-a -mfloat-abi=hard -mfpu=neon -marm -mthumb-interwork worked.

I have the same issue but I resolve issue from database.I had rename table name and create new table with out index through which all indexes effected and I had huge amount of data in table.I again rename original table, it has fixed for me.

I had the same requirement in my development so I did research on this. I have read many articles and tried many solutions during last two days like jQuery.tabNext() plugin.

I had some trouble with IE11 (all IE version has this bug). When an input text followed by non text input the selection was not cleared. So I have created my own tabNext() method based on @Sarfraz solution suggestion. I was also thinking on how it should behave (only circle in the current form or maybe through the full document). I still did not take care of the tabindex property mostly because I am using it occasionally. But I will not forget it.

In order to my contribution can be useful for everybody easily I have created jsfiddle example here https://jsfiddle.net/mkrivan/hohx4nes/

I include also the JavaScript part of the example here:

            function clearSelection() {
            if (document.getSelection) { // for all new browsers (IE9+, Chrome, Firefox)
                document.getSelection().removeAllRanges();
                document.getSelection().addRange(document.createRange());
                console.log("document.getSelection");
            } else if (window.getSelection) { // equals with the document.getSelection (MSDN info)
                if (window.getSelection().removeAllRanges) {  // for all new browsers (IE9+, Chrome, Firefox)
                    window.getSelection().removeAllRanges();
                    window.getSelection().addRange(document.createRange());
                    console.log("window.getSelection.removeAllRanges");
                } else if (window.getSelection().empty) {  // maybe for old Chrome
                    window.getSelection().empty();
                    console.log("window.getSelection.empty");
                }
            } else if (document.selection) {  // IE8- deprecated
                document.selection.empty();
                console.log("document.selection.empty");
            }
        }
        function focusNextInputElement(node) { // instead of jQuery.tabNext();
            // TODO: take the tabindex into account if defined
            if (node !== null) {
                // stay in the current form
                var inputs = $(node).parents("form").eq(0).find(":input:visible:not([disabled]):not([readonly])");
                // if you want through the full document (as TAB key is working)
                // var inputs = $(document).find(":input:visible:not([disabled]):not([readonly])");
                var idx = inputs.index(node) + 1; // next input element index
                if (idx === inputs.length) { // at the end start with the first one
                    idx = 0;
                }
                var nextInputElement = inputs[idx];
                nextInputElement.focus(); //  handles submit buttons
                try { // if next input element does not support select()
                    nextInputElement.select();
                } catch (e) {
                }
            }
        }
        function tabNext() {
            var currentActiveNode = document.activeElement;
            clearSelection();
            focusNextInputElement(currentActiveNode);
        }
        function stopReturnKey(e) {
            var e = (e) ? e : ((event) ? event : null);
            if (e !== null) {
                var node = (e.target) ? e.target : ((e.srcElement) ? e.srcElement : null);
                if (node !== null) {
                    var requiredNode = $(node).is(':input')
                            // && !$(node).is(':input[button]')
                            // && !$(node).is(':input[type="submit"]')
                            && !$(node).is('textarea');
                    // console.log('event key code ' + e.keyCode + '; required node ' + requiredNode);
                    if ((e.keyCode === 13) && requiredNode) {
                        try {
                            tabNext();
                            // clearSelection();
                            // focusNextInputElement(node);
                            // jQuery.tabNext();
                            console.log("success");
                        } catch (e) {
                            console.log("error");
                        }
                        return false;
                    }
                }
            }
        }
        document.onkeydown = stopReturnKey;

I left commented rows as well so my thinking can be followed.

for total compatibility with twitter bootstrap 3, I need to override some plugins methods:

// override jquery validate plugin defaults
$.validator.setDefaults({
    highlight: function(element) {
        $(element).closest('.form-group').addClass('has-error');
    },
    unhighlight: function(element) {
        $(element).closest('.form-group').removeClass('has-error');
    },
    errorElement: 'span',
    errorClass: 'help-block',
    errorPlacement: function(error, element) {
        if(element.parent('.input-group').length) {
            error.insertAfter(element.parent());
        } else {
            error.insertAfter(element);
        }
    }
});

See Example: http://jsfiddle.net/mapb_1990/hTPY7/7/

Export like export default HelloWorld; and import, such as import React from 'react' are part of the ES6 modules system.

A module is a self contained unit that can expose assets to other modules using export, and acquire assets from other modules using import.

In your code:

import React from 'react'; // get the React object from the react module

class HelloWorld extends React.Component {
  render() {
    return <p>Hello, world!</p>;
  }
}

export default HelloWorld; // expose the HelloWorld component to other modules

In ES6 there are two kinds of exports:

Named exports - for example export function func() {} is a named export with the name of func. Named modules can be imported using import { exportName } from 'module';. In this case, the name of the import should be the same as the name of the export. To import the func in the example, you'll have to use import { func } from 'module';. There can be multiple named exports in one module.

Default export - is the value that will be imported from the module, if you use the simple import statement import X from 'module'. X is the name that will be given locally to the variable assigned to contain the value, and it doesn't have to be named like the origin export. There can be only one default export.

A module can contain both named exports and a default export, and they can be imported together using import defaultExport, { namedExport1, namedExport3, etc... } from 'module';.

InetAddress.getLocalHost().getHostName() is the best way out of the two as this is the best abstraction at the developer level.

First, turn off compression:

git config --global core.compression 0

Next, let's do a partial clone to truncate the amount of info coming down:

git clone --depth 1 <repo_URI>

When that works, go into the new directory and retrieve the rest of the clone:

git fetch --unshallow 

or, alternately,

git fetch --depth=2147483647

Now, do a regular pull:

git pull --all

I think there is a glitch with msysgit in the 1.8.x versions that exacerbates these symptoms, so another option is to try with an earlier version of git (<= 1.8.3, I think).

Your code seems to be fine, make sure that key you specify really exists in the array or such key has a value in your array eg:

$array = array(4 => 'Hello There');
print_r(array_keys($array));
// or better
print_r($array);

Output:

Array
(
    [0] => 4
)

Now:

$key = 4;
$value = $array[$key];
print $value;

Output:

Hello There

Using pure java-script, here is a working code example

<input type="checkbox" name="fruit1" checked/>
<input type="checkbox" name="fruit2" checked />

<input type="checkbox" name="other1" checked />
<input type="checkbox" name="other2" checked />
<br>
<input type="button" name="check" value="count checked checkboxes name starts with fruit*" onClick="checkboxes();" />


<script>
function checkboxes()
{
var inputElems = document.getElementsByTagName("input"),
count = 0;
for (var i=0; i<inputElems.length; i++) {       
if (inputElems[i].type == "checkbox" && inputElems[i].checked == true && 
inputElems[i].name.indexOf('fruit') == 0) 
{
count++;

}

}
alert(count);
}
</script>

I want to present performance of different approaches, on Python 3.4, Linux x64. Excerpt from line profiler:

      Line #      Hits         Time  Per Hit   % Time  Line Contents
      ==============================================================
         (...)
         823      1508        11334      7.5     41.6          yday = int(period_end.strftime('%j'))
         824      1508         2492      1.7      9.1          yday = period_end.toordinal() - date(period_end.year, 1, 1).toordinal() + 1
         825      1508         1852      1.2      6.8          yday = (period_end - date(period_end.year, 1, 1)).days + 1
         826      1508         5078      3.4     18.6          yday = period_end.timetuple().tm_yday
         (...)

So most efficient is

yday = (period_end - date(period_end.year, 1, 1)).days

To store the array values in cookie, first you need to convert them to string, so here is some options.

Storing cookies as JSON

Storing code

setcookie('your_cookie_name', json_encode($info), time()+3600);

Reading code

$data = json_decode($_COOKIE['your_cookie_name'], true);

JSON can be good choose also if you need read cookie in front end with JavaScript.

Actually you can use any encrypt_array_to_string/decrypt_array_from_string methods group that will convert array to string and convert string back to same array. For example you can also use explode/implode for array of integers.

Warning: Do not use serialize/unserialize

From PHP.net

Do not pass untrusted user input to unserialize(). - Anything that coming by HTTP including cookies is untrusted!

As an alternative solution, you can do it also without converting array to string.

setcookie('my_array[0]', 'value1' , time()+3600);
setcookie('my_array[1]', 'value2' , time()+3600);
setcookie('my_array[2]', 'value3' , time()+3600);

And after if you will print $_COOKIE variable, you will see the following

echo '<pre>';
print_r( $_COOKIE );
die();

Array
(   
    [my_array] => Array
        (
            [0] => value1
            [1] => value2
            [2] => value3
        )

)

This is documented PHP feature.

From PHP.net

Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the user's system.

The compiler needs to know the size of the second dimension in your two dimensional array. For example:

void print_graph(g_node graph_node[], double weight[][5], int nodes);

this does not disable the spam checking

div.g-recaptcha > div.grecaptcha-badge {
    width:0 !important;
}

A StringBuilder will help you when you need to build strings in multiple steps.

Instead of doing this:

String x = "";
x += "first ";
x += "second ";
x += "third ";

you do

StringBuilder sb = new StringBuilder("");
sb.Append("first ");
sb.Append("second ");
sb.Append("third");
String x = sb.ToString();

The final effect is the same, but the StringBuilder will use less memory and will run faster. Instead of creating a new string which is the concatenation of the two, it will create the chunks separately, and only at the end it will unite them.

All you have to do is wrap your content inside a Grid Container tag, specify the spacing, then wrap the actual content inside a Grid Item tag.

 <Grid container spacing={24}>
    <Grid item xs={8}>
      <leftHeaderContent/>
    </Grid>

    <Grid item xs={3}>
      <rightHeaderContent/>
    </Grid>
  </Grid>

Also, I've struggled with material grid a lot, I suggest you checkout flexbox which is built into CSS automatically and you don't need any addition packages to use. Its very easy to learn.

Your question is similar to below:

What is the difference between application server and web server?

In Java: Web Container or Servlet Container or Servlet Engine : is used to manage the components like Servlets, JSP. It is a part of the web server.

Web Server or HTTP Server: A server which is capable of handling HTTP requests, sent by a client and respond back with a HTTP response.

Application Server or App Server: can handle all application operations between users and an organization's back end business applications or databases.It is frequently viewed as part of a three-tier application with: Presentation tier, logic tier,Data tier

DllImport will work fine without the complete path specified as long as the dll is located somewhere on the system path. You may be able to temporarily add the user's folder to the path.

String s = "";
s.length();

String s = null;
s.length();

A reference to an empty string "" points to an object in the heap - so you can call methods on it.

But a reference pointing to null has no object to point in the heap and thus you'll get a NullPointerException.

Or simply:

view.getLayoutParams().width = 400;
view.requestLayout();

def chunker(seq, size):
    return (seq[pos:pos + size] for pos in range(0, len(seq), size))
# (in python 2 use xrange() instead of range() to avoid allocating a list)

Works with any sequence:

text = "I am a very, very helpful text"

for group in chunker(text, 7):
   print(repr(group),)
# 'I am a ' 'very, v' 'ery hel' 'pful te' 'xt'

print '|'.join(chunker(text, 10))
# I am a ver|y, very he|lpful text

animals = ['cat', 'dog', 'rabbit', 'duck', 'bird', 'cow', 'gnu', 'fish']

for group in chunker(animals, 3):
    print(group)
# ['cat', 'dog', 'rabbit']
# ['duck', 'bird', 'cow']
# ['gnu', 'fish']

Try this on your position:fixed element.

overflow-y: scroll;
max-height: 100%;

You can do this :

<table id="table_header">
<tr>
   <td contenteditable="true">a</td>
   <td contenteditable="true">b</td>
   <td contenteditable="true">c</td>
</tr>
</table>

A very readable example from another post on similar topic:

var args = [ 'p0', 'p1', 'p2' ];

function call_me (param0, param1, param2 ) {
    // ...
}

// Calling the function using the array with apply()
call_me.apply(this, args);

And here a link to the original post that I personally liked for its readability

You can use Membership operator:

def list = ['Grace','Rob','Emmy']
assert ('Emmy' in list)  

Membership operator Groovy

Use the type() builtin function:

>>> i = 123
>>> type(i)
<type 'int'>
>>> type(i) is int
True
>>> i = 123.456
>>> type(i)
<type 'float'>
>>> type(i) is float
True

To check if a variable is of a given type, use isinstance:

>>> i = 123
>>> isinstance(i, int)
True
>>> isinstance(i, (float, str, set, dict))
False

Note that Python doesn't have the same types as C/C++, which appears to be your question.

in your servlet

 request.setAttribute("submitDone","done");
 return mapping.findForward("success");

In your jsp

<c:if test="${not empty submitDone}">
  <script>alert("Form submitted");
</script></c:if>

If you know the position, why not just get the index from that?

Then use .loc:

df.loc[index, 'COL_NAME'] = x

The append() method adds a single item to the existing list

some_list1 = []
some_list1.append("something")

So here the some_list1 will get modified.

Updated:

Whereas using + to combine the elements of lists (more than one element) in the existing list similar to the extend (as corrected by Flux).

some_list2 = []
some_list2 += ["something"]

So here the some_list2 and ["something"] are the two lists that are combined.

append a text node as follows

var td1 = document.getElementById('td1');
var text = document.createTextNode("some text");
td1.appendChild(text);

Using Array.Filter() with Arrow Functions we can achieve this using

users = users.filter(x => x.name == 'Mark' && x.address == 'England');

Here is the complete snippet

// initializing list of users_x000D_
var users = [{_x000D_
    name: 'John',_x000D_
    email: '[email protected]',_x000D_
    age: 25,_x000D_
    address: 'USA'_x000D_
  },_x000D_
  {_x000D_
    name: 'Tom',_x000D_
    email: '[email protected]',_x000D_
    age: 35,_x000D_
    address: 'England'_x000D_
  },_x000D_
  {_x000D_
    name: 'Mark',_x000D_
    email: '[email protected]',_x000D_
    age: 28,_x000D_
    address: 'England'_x000D_
  }_x000D_
];_x000D_
_x000D_
//filtering the users array and saving _x000D_
//result back in users variable_x000D_
users = users.filter(x => x.name == 'Mark' && x.address == 'England');_x000D_
_x000D_
_x000D_
//logging out the result in console_x000D_
console.log(users);

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,
              /* --> */  SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions // <---
    };

    return file.Id;
}

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <---
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = SupportedPermissions.basic // <---
    };

    return file.Id;
}

Syntax:

$(selector).text() returns the text content.

$(selector).text(content) sets the text content.

$(selector).text(function(index, curContent)) sets text content using a function.

I answered a very similar question, and here is a way of doing this :

First, create a file where you would define your animations and export them. Just to make it more clear in your app.component.ts

In the following example, I used a max-height of the div that goes from 0px (when it's hidden), to 500px, but you would change that according to what you need.

This animation uses states (in and out), that will be toggle when we click on the button, which will run the animtion.

animations.ts

import { trigger, state, style, transition,
    animate, group, query, stagger, keyframes
} from '@angular/animations';

export const SlideInOutAnimation = [
    trigger('slideInOut', [
        state('in', style({
            'max-height': '500px', 'opacity': '1', 'visibility': 'visible'
        })),
        state('out', style({
            'max-height': '0px', 'opacity': '0', 'visibility': 'hidden'
        })),
        transition('in => out', [group([
            animate('400ms ease-in-out', style({
                'opacity': '0'
            })),
            animate('600ms ease-in-out', style({
                'max-height': '0px'
            })),
            animate('700ms ease-in-out', style({
                'visibility': 'hidden'
            }))
        ]
        )]),
        transition('out => in', [group([
            animate('1ms ease-in-out', style({
                'visibility': 'visible'
            })),
            animate('600ms ease-in-out', style({
                'max-height': '500px'
            })),
            animate('800ms ease-in-out', style({
                'opacity': '1'
            }))
        ]
        )])
    ]),
]

Then in your app.component, we import the animation and create the method that will toggle the animation state.

app.component.ts

import { SlideInOutAnimation } from './animations';

@Component({
  ...
  animations: [SlideInOutAnimation]
})
export class AppComponent  {
  animationState = 'in';

  ...

  toggleShowDiv(divName: string) {
    if (divName === 'divA') {
      console.log(this.animationState);
      this.animationState = this.animationState === 'out' ? 'in' : 'out';
      console.log(this.animationState);
    }
  }
}

And here is how your app.component.html would look like :

<div class="wrapper">
  <button (click)="toggleShowDiv('divA')">TOGGLE DIV</button>
  <div [@slideInOut]="animationState" style="height: 100px; background-color: red;">
  THIS DIV IS ANIMATED</div>
  <div class="content">THIS IS CONTENT DIV</div>
</div>

slideInOut refers to the animation trigger defined in animations.ts

Side note : If an error ever occurs and asks you to add BrowserAnimationsModule, just import it in your app.module.ts:

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
  imports: [ ..., BrowserAnimationsModule ],

public void schedule(TimerTask task,long delay)

Schedules the specified task for execution after the specified delay.

you want:

public void schedule(TimerTask task, long delay, long period)

Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals separated by the specified period.

You can do a Runtime.getRuntime.exec(command) to relaunch the jar including classpath with args.

Here are some thoughts and ideas:

Use ROM more creatively.

Store anything you can in ROM. Instead of calculating things, store look-up tables in ROM. (Make sure your compiler is outputting your look-up tables to the read-only section! Print out memory addresses at runtime to check!) Store your interrupt vector table in ROM. Of course, run some tests to see how reliable your ROM is compared to your RAM.

Use your best RAM for the stack.

SEUs in the stack are probably the most likely source of crashes, because it is where things like index variables, status variables, return addresses, and pointers of various sorts typically live.

Implement timer-tick and watchdog timer routines.

You can run a "sanity check" routine every timer tick, as well as a watchdog routine to handle the system locking up. Your main code could also periodically increment a counter to indicate progress, and the sanity-check routine could ensure this has occurred.

Implement error-correcting-codes in software.

You can add redundancy to your data to be able to detect and/or correct errors. This will add processing time, potentially leaving the processor exposed to radiation for a longer time, thus increasing the chance of errors, so you must consider the trade-off.

Remember the caches.

Check the sizes of your CPU caches. Data that you have accessed or modified recently will probably be within a cache. I believe you can disable at least some of the caches (at a big performance cost); you should try this to see how susceptible the caches are to SEUs. If the caches are hardier than RAM then you could regularly read and re-write critical data to make sure it stays in cache and bring RAM back into line.

Use page-fault handlers cleverly.

If you mark a memory page as not-present, the CPU will issue a page fault when you try to access it. You can create a page-fault handler that does some checking before servicing the read request. (PC operating systems use this to transparently load pages that have been swapped to disk.)

Use assembly language for critical things (which could be everything).

With assembly language, you know what is in registers and what is in RAM; you know what special RAM tables the CPU is using, and you can design things in a roundabout way to keep your risk down.

Use objdump to actually look at the generated assembly language, and work out how much code each of your routines takes up.

If you are using a big OS like Linux then you are asking for trouble; there is just so much complexity and so many things to go wrong.

Remember it is a game of probabilities.

A commenter said

Every routine you write to catch errors will be subject to failing itself from the same cause.

While this is true, the chances of errors in the (say) 100 bytes of code and data required for a check routine to function correctly is much smaller than the chance of errors elsewhere. If your ROM is pretty reliable and almost all the code/data is actually in ROM then your odds are even better.

Use redundant hardware.

Use 2 or more identical hardware setups with identical code. If the results differ, a reset should be triggered. With 3 or more devices you can use a "voting" system to try to identify which one has been compromised.

There are various ways to print size of an array. Here are the meanings of all:

Let’s say our array is my @arr = (3,4);

Method 1: scalar

This is the right way to get the size of arrays.

print scalar @arr;  # Prints size, here 2

Method 2: Index number

$#arr gives the last index of an array. So if array is of size 10 then its last index would be 9.

print $#arr;     # Prints 1, as last index is 1
print $#arr + 1; # Adds 1 to the last index to get the array size

We are adding 1 here, considering the array as 0-indexed. But, if it's not zero-based then, this logic will fail.

perl -le 'local $[ = 4; my @arr = (3, 4); print $#arr + 1;'   # prints 6

The above example prints 6, because we have set its initial index to 4. Now the index would be 5 and 6, with elements 3 and 4 respectively.

Method 3:

When an array is used in a scalar context, then it returns the size of the array

my $size = @arr;
print $size;   # Prints size, here 2

Actually, method 3 and method 1 are same.

You can add information about parameters, returns, etc. as well using:

/**
* This is the foo function
* @param bar This is the bar parameter
* @returns returns a string version of bar
*/
function foo(bar: number): string {
    return bar.toString()
}

This will cause editors like VS Code to display it as the following:

Try this process -

Open the Query Analyzer

Start --> Programs --> MS SQL Server --> Query Analyzer

Once opened, connect to the database that you are wish running the script on.

Next, open the SQL file using File --> Open option. Select .sql file.

Once it is open, you can execute the file by pressing F5.

You may be able to use LINQ (to SQL), and you may be able to make use of the Dynamic Query LINQ sample from MS. http://weblogs.asp.net/scottgu/archive/2008/01/07/dynamic-linq-part-1-using-the-linq-dynamic-query-library.aspx

You need to extract the initilization of time() out of the for loop.

Here is an example that will output in the windows console expected (ahah) random number.

#include <iostream>
#include <windows.h>
#include "time.h"
int main(int argc, char*argv[])
{
    srand ( time(NULL) );
    for (int t = 0; t < 10; t++)
    {
        int random_x;

        random_x = rand() % 100;
        std::cout << "\nRandom X = " << random_x << std::endl;
    }
    Sleep(50000);
    return 0;
}

To read some specific column I did something like this:

dpkcs.csv content:
FN,LN,EMAIL,CC
Name1,Lname1,[email protected],CC1
Nmae2,Lname2,[email protected],CC2

The function to read it:

private void getEMailRecepientList() {
                List<EmailRecepientData> emailList = null;// Blank list of POJO class
                Scanner scanner = null;
                BufferedReader reader = null;
                try {
                    reader = new BufferedReader(new FileReader("dpkcs.csv"));
                    Map<String, Integer> mailHeader = new HashMap<String, Integer>();
                    // read file line by line
                    String line = null;
                    int index = 0;
                    line = reader.readLine();
                    // Get header from 1st row of csv
                    if (line != null) {
                        StringTokenizer str = new StringTokenizer(line, ",");
                        int headerCount = str.countTokens();
                        for (int i = 0; i < headerCount; i++) {
                            String headerKey = str.nextToken();
                            mailHeader.put(headerKey.toUpperCase(), new Integer(i));

                        }
                    }
                    emailList = new ArrayList<EmailRecepientData>();

                    while ((line = reader.readLine()) != null) {
                    // POJO class for getter and setters
                        EmailRecepientData email = new EmailRecepientData();
                        scanner = new Scanner(line);
                        scanner.useDelimiter(",");
                    //Use Specific key to get value what u want
                        while (scanner.hasNext()) {
                            String data = scanner.next();
                            if (index == mailHeader.get("EMAIL"))
                                email.setEmailId(data);
                            else if (index == mailHeader.get("FN"))
                                email.setFirstName(data);
                            else if (index == mailHeader.get("LN"))
                                email.setLastName(data);
                            else if (index == mailHeader.get("CC"))
                                email.setCouponCode(data);

                            index++;
                        }
                        index = 0;
                        emailList.add(email);
                    }
                    reader.close();
                } catch (Exception e) {
                    StringWriter stack = new StringWriter();
                    e.printStackTrace(new PrintWriter(stack));

                } finally {
                    scanner.close();
                }

                System.out.println("list--" + emailList);

            }

The POJO Class:

public class EmailRecepientData {
    private String emailId;
    private String firstName;
    private String lastName;
    private String couponCode;

    public String getEmailId() {
        return emailId;
    }

    public void setEmailId(String emailId) {
        this.emailId = emailId;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getCouponCode() {
        return couponCode;
    }

    public void setCouponCode(String couponCode) {
        this.couponCode = couponCode;
    }

    @Override
    public String toString() {
        return "Email Id=" + emailId + ", First Name=" + firstName + " ,"
                + " Last Name=" + lastName + ", Coupon Code=" + couponCode + "";
    }

}

There is actually a truly invisible character: U+FEFF. This character is called the Byte Order Mark and is related to the Unicode 8 system. It is a really confusing concept that can be explained HERE The Byte Order Mark or BOM for short is an invisible character that doesn't take up any space. You can copy the character bellow between the > and <.

Here is the character:

> <

How to catch this character in action:

• Copy the character between the > and <,
• Write a line of text, then randomly put your caret in the line of text
• Paste the character in the line.
• Go to the beginning of the line and press and hold the right arrow key.

You will notice that when your caret gets to the place you pasted the character, it will briefly stop for around half a second. This is becuase the caret is passing over the invisible character. Even though you can't see it doesn't mean it isn't there. The caret still sees that there is a character in that area that you pasted the BOM and will pass through it. Since the BOM is invisble, the caret will look like it has paused for a brief moment. You can past the BOM multiple times in an area and redo the steps above to really show the affect. Good luck!

EDIT: Sadly, Stackoverflow doesn't like the character. Here is an example from w3.org: https://www.w3.org/International/questions/examples/phpbomtest.php

If anyone wanted to download it as well.
Here is an awesome little function that will convert an array of JSON objects to csv, then download it.

downloadCSVFromJson = (filename, arrayOfJson) => {
  // convert JSON to CSV
  const replacer = (key, value) => value === null ? '' : value // specify how you want to handle null values here
  const header = Object.keys(arrayOfJson[0])
  let csv = arrayOfJson.map(row => header.map(fieldName => 
  JSON.stringify(row[fieldName], replacer)).join(','))
  csv.unshift(header.join(','))
  csv = csv.join('\r\n')

  // Create link and download
  var link = document.createElement('a');
  link.setAttribute('href', 'data:text/csv;charset=utf-8,%EF%BB%BF' + encodeURIComponent(csv));
  link.setAttribute('download', filename);
  link.style.visibility = 'hidden';
  document.body.appendChild(link);
  link.click();
  document.body.removeChild(link);
};

Then call it like this:

this.downloadCSVFromJson(`myCustomName.csv`, this.state.csvArrayOfJson)

I'd go for jpeg. Read this post regarding image size reduction and after deciding on the technique, use ImageMagick

Hope this helps

Why not use a PdfPTable object for this? Create a fixed width table and use a float array to set the widths of the columns

PdfPTable table = new PdfPTable(10);
table.HorizontalAlignment = 0;
table.TotalWidth = 500f;
table.LockedWidth = true;
float[] widths = new float[] { 20f, 60f, 60f, 30f, 50f, 80f, 50f, 50f, 50f, 50f };
table.SetWidths(widths);

addCell(table, "SER.\nNO.", 2);

addCell(table, "TYPE OF SHIPPING", 1);
addCell(table, "ORDER NO.", 1);
addCell(table, "QTY.", 1);
addCell(table, "DISCHARGE PPORT", 1);

addCell(table, "DESCRIPTION OF GOODS", 2);

addCell(table, "LINE DOC. RECL DATE", 1);

addCell(table, "CLEARANCE DATE", 2);
addCell(table, "CUSTOM PERMIT NO.", 2);
addCell(table, "DISPATCH DATE", 2);

addCell(table, "AWB/BL NO.", 1);
addCell(table, "COMPLEX NAME", 1);
addCell(table, "G. W. Kgs.", 1);
addCell(table, "DESTINATION", 1);
addCell(table, "OWNER DOC. RECL DATE", 1);

....

private static void addCell(PdfPTable table, string text, int rowspan)
{
    BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
    iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);

    PdfPCell cell = new PdfPCell(new Phrase(text, times));
    cell.Rowspan = rowspan;
    cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
    cell.VerticalAlignment = PdfPCell.ALIGN_MIDDLE;
    table.AddCell(cell);
}

have a look at this tutorial too...

Will result always be the floor of the division? What is the defined behavior?

Not quite. It rounds toward 0, rather than flooring.

6.5.5 Multiplicative operators

6 When integers are divided, the result of the / operator is the algebraic quotient with any fractional part discarded.⁸⁸⁾ If the quotient a/b is representable, the expression (a/b)*b + a%b shall equal a.

and the corresponding footnote:

88. This is often called ‘‘truncation toward zero’’.

Of course two points to note are:

3 The usual arithmetic conversions are performed on the operands.

and:

5 The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder. In both operations, if the value of the second operand is zero, the behavior is undefined.

[Note: Emphasis mine]

To split the difference of opinion

I prefer:

   xls.DisplayAlerts = False    
   wb.SaveAs fullFilePath, AccessMode:=xlExclusive, ConflictResolution:=xlLocalSessionChanges
   xls.DisplayAlerts = True

cmsjr had the right solution. I just wanted to point out a couple of things for your future trigger development. If you are using the values statement in an insert in a trigger, there is a stong possibility that you are doing the wrong thing. Triggers fire once for each batch of records inserted, deleted, or updated. So if ten records were inserted in one batch, then the trigger fires once. If you are refering to the data in the inserted or deleted and using variables and the values clause then you are only going to get the data for one of those records. This causes data integrity problems. You can fix this by using a set-based insert as cmsjr shows above or by using a cursor. Don't ever choose the cursor path. A cursor in a trigger is a problem waiting to happen as they are slow and may well lock up your table for hours. I removed a cursor from a trigger once and improved an import process from 40 minutes to 45 seconds.

You may think nobody is ever going to add multiple records, but it happens more frequently than most non-database people realize. Don't write a trigger that will not work under all the possible insert, update, delete conditions. Nobody is going to use the one record at a time method when they have to import 1,000,000 sales target records from a new customer or update all the prices by 10% or delete all the records from a vendor whose products you don't sell anymore.

You do not need to pass the size parameter, just declare Varchar already understands that it is MAX like:

cmd.Parameters.Add("@blah",SqlDbType.VarChar).Value = "some large text";

You can use sshpass utility as below,

$ sshpass -p "your pass" ansible pattern -m module -a args \
   -i inventory --ask-sudo-pass

You can also explicitly tell maven which java version to compile for. You can try adding the maven-compiler-plugin to your pom.

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
          <source>1.7</source>
          <target>1.7</target>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>

If you imported a maven project into an IDE, then there is probably a maven setting in your IDE for default compiler that your maven runner is using.

You can declare local variables in MySQL triggers, with the DECLARE syntax.

Here's an example:

DROP TABLE IF EXISTS foo;
CREATE TABLE FOO (
  i SERIAL PRIMARY KEY
);

DELIMITER //
DROP TRIGGER IF EXISTS bar //

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = NEW.i;
  SET @a = x; -- set user variable outside trigger
END//

DELIMITER ;

SET @a = 0;

SELECT @a; -- returns 0

INSERT INTO foo () VALUES ();

SELECT @a; -- returns 1, the value it got during the trigger

When you assign a value to a variable, you must ensure that the query returns only a single value, not a set of rows or a set of columns. For instance, if your query returns a single value in practice, it's okay but as soon as it returns more than one row, you get "ERROR 1242: Subquery returns more than 1 row".

You can use LIMIT or MAX() to make sure that the local variable is set to a single value.

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = (SELECT age FROM users WHERE name = 'Bill'); 
  -- ERROR 1242 if more than one row with 'Bill'
END//

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = (SELECT MAX(age) FROM users WHERE name = 'Bill');
  -- OK even when more than one row with 'Bill'
END//

 $(document).ready(function () {
    $('.dates li a').click(function (e) {

        $('.dates li a').removeClass('active');

        var $parent = $(this);
        if (!$parent.hasClass('active')) {
            $parent.addClass('active');
        }
        e.preventDefault();
    });
});

Basically, you check if an object is an instance of a specific class. You normally use it, when you have a reference or parameter to an object that is of a super class or interface type and need to know whether the actual object has some other type (normally more concrete).

Example:

public void doSomething(Number param) {
  if( param instanceof Double) {
    System.out.println("param is a Double");
  }
  else if( param instanceof Integer) {
    System.out.println("param is an Integer");
  }

  if( param instanceof Comparable) {
    //subclasses of Number like Double etc. implement Comparable
    //other subclasses might not -> you could pass Number instances that don't implement that interface
    System.out.println("param is comparable"); 
  }
}

Note that if you have to use that operator very often it is generally a hint that your design has some flaws. So in a well designed application you should have to use that operator as little as possible (of course there are exceptions to that general rule).

Use ngInit: https://docs.angularjs.org/api/ng/directive/ngInit

<div ng-repeat="day in forecast_days" ng-init="f = forecast[day.iso]">
  {{$index}} - {{day.iso}} - {{day.name}}
  Temperature: {{f.temperature}}<br>
  Humidity: {{f.humidity}}<br>
  ...
</div>

It stands for Representational State Transfer and it can mean a lot of things, but usually when you are talking about APIs and applications, you are talking about REST as a way to do web services or get programs to talk over the web.

REST is basically a way of communicating between systems and does much of what SOAP RPC was designed to do, but while SOAP generally makes a connection, authenticates and then does stuff over that connection, REST works pretty much the same way that that the web works. You have a URL and when you request that URL you get something back. This is where things start getting confusing because people describe the web as a the largest REST application and while this is technically correct it doesn't really help explain what it is.

In a nutshell, REST allows you to get two applications talking over the Internet using tools that are similar to what a web browser uses. This is much simpler than SOAP and a lot of what REST does is says, "Hey, things don't have to be so complex."

You can implement this using Java 8 lambdas.

import java.util.HashMap;
import java.util.Map;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.event.Level;

public class LevelLogger {
    private static final Logger LOGGER = LoggerFactory.getLogger(LevelLogger.class);
    private static final Map<Level, LoggingFunction> map;

    static {
        map = new HashMap<>();
        map.put(Level.TRACE, (o) -> LOGGER.trace(o));
        map.put(Level.DEBUG, (o) -> LOGGER.debug(o));
        map.put(Level.INFO, (o) -> LOGGER.info(o));
        map.put(Level.WARN, (o) -> LOGGER.warn(o));
        map.put(Level.ERROR, (o) -> LOGGER.error(o));
    }

    public static void log(Level level, String s) {
        map.get(level).log(s);
    }

    @FunctionalInterface
    private interface LoggingFunction {
        public void log(String arg);
    }
}

StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace();

The last element of the array represents the bottom of the stack, which is the least recent method invocation in the sequence.

A StackTraceElement has getClassName(), getFileName(), getLineNumber() and getMethodName().

loop through StackTraceElement and get your desired result.

for (StackTraceElement ste : stackTraceElements ) 
{
    //do your stuff here...
}

This is not only applicable in Modernizer. I see some site implement like below to check whether it has javascript support or not.

<body class="no-js">
    <script>document.body.classList.remove('no-js');</script>
    ...
</body>

If javascript support is there, then it will remove no-js class. Otherwise no-js will remain in the body tag. Then they control the styles in the css when no javascript support.

.no-js .some-class-name {

}

In Tensorflow 1.x

import tensorflow as tf
tf.enable_eager_execution()
matrix1 = tf.constant([[3., 3.]])
matrix2 = tf.constant([[2.],[2.]])
product = tf.matmul(matrix1, matrix2)

#print the product
print(product)         # tf.Tensor([[12.]], shape=(1, 1), dtype=float32)
print(product.numpy()) # [[12.]]

With Tensorflow 2.x, eager mode is enabled by default. so the following code works with TF2.0.

import tensorflow as tf
matrix1 = tf.constant([[3., 3.]])
matrix2 = tf.constant([[2.],[2.]])
product = tf.matmul(matrix1, matrix2)

#print the product
print(product)         # tf.Tensor([[12.]], shape=(1, 1), dtype=float32)
print(product.numpy()) # [[12.]]

It means the respective method is not present in the class:

1. If you are using jar then decompile and check if the respective version of jar have proper class.
2. Check if you have compiled proper class from your source.

This is fixed in version 1.6 of the plugin.

            <groupId>org.codehaus.mojo</groupId>
            <artifactId>jaxb2-maven-plugin</artifactId>
            <version>1.6</version>

Quick note though, I noticed that the first iteration output was being deleted. I fixed it by adding the following to each of the executions.

                        <removeOldOutput>false</removeOldOutput>
                        <clearOutputDir>false</clearOutputDir>

Here is my full working example with each iteration outputting correctly. BTW I had to do this due to a duplicate namespace problem with the xsd's I was given. This seems to resolve my problem.
