Try this:

Calendar calendar = Calendar.getInstance();
calendar.setTime(yourdate);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
int minutes = calendar.get(Calendar.MINUTE);
int seconds = calendar.get(Calendar.SECOND);

Edit:

hours, minutes, seconds

above will be the hours, minutes and seconds after converting yourdate to System Timezone!

This seems to me to be what the question is after, no need for formatters:

NSDate *date = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:date];
NSInteger hour = [components hour];
NSInteger minute = [components minute];

select case when [am or _pm] ='PM' and datepart(HOUR,time_received)<>12 
           then dateadd(hour,12,time_received) 
           else time_received 
       END 
from table

works

You can use strtotime() to achieve this:

$new_time = date("Y-m-d H:i:s", strtotime('+3 hours', $now)); // $now + 3 hours

First of All you should download the Android SDK. Download here:
http://developer.android.com/sdk/index.html

Then, as stated in the SDK README:

The Android SDK archive now only contains the tools. It no longer comes populated with a specific Android platform or Google add-on. Instead you use the SDK Manager to install or update SDK components such as platforms, tools, add-ons, and documentation.

I'm not absolutely sure I got your question correctly, but it seems you want something like this:

    Class c = null;
    try {
        c = Class.forName("com.path.to.ImplementationType");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    T interfaceType = null;
    try {
        interfaceType = (T) c.newInstance();
    } catch (InstantiationException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }

Where T can be defined in method level or in class level, i.e. <T extends InterfaceType>

One major disadvantage of SPA - SEO. Only recently Google and Bing started indexing Ajax-based pages by executing JavaScript during crawling, and still in many cases pages are being indexed incorrectly.

While developing SPA, you will be forced to handle SEO issues, probably by post-rendering all your site and creating static html snapshots for crawler's use. This will require a solid investment in a proper infrastructures.

Update 19.06.16:

Since writing this answer a while ago, I gain much more experience with Single Page Apps (namely, AngularJS 1.x) - so I have more info to share.

In my opinion, the main disadvantage of SPA applications is SEO, making them limited to kind of "dashboard" apps only. In addition, you are going to have a much harder times with caching, compared to classic solutions. For example, in ASP.NET caching is extreamly easy - just turn on OutputCaching and you are good: the whole HTML page will be cached according to URL (or any other parameters). However, in SPA you will need to handle caching yourself (by using some solutions like second level cache, template caching, etc..).

I have a similar problem. I need users to submit html content to a profile page with a great WYSIWYG editor (Redactorjs!), i wrote the following function to clean the submitted html:

    <?php function filterxss($str) {
//Initialize DOM:
$dom = new DOMDocument();
//Load content and add UTF8 hint:
$dom->loadHTML('<meta http-equiv="content-type" content="text/html; charset=utf-8">'.$str);
//Array holds allowed attributes and validation rules:
$check = array('src'=>'#(http://[^\s]+(?=\.(jpe?g|png|gif)))#i','href'=>'|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i');
//Loop all elements:
foreach($dom->getElementsByTagName('*') as $node){
    for($i = $node->attributes->length -1; $i >= 0; $i--){
        //Get the attribute:
        $attribute = $node->attributes->item($i);
        //Check if attribute is allowed:
        if( in_array($attribute->name,array_keys($check))) {
            //Validate by regex:    
            if(!preg_match($check[$attribute->name],$attribute->value)) { 
                //No match? Remove the attribute
                $node->removeAttributeNode($attribute); 
            }
        }else{
            //Not allowed? Remove the attribute:
            $node->removeAttributeNode($attribute);
        }
    }
}
var_dump($dom->saveHTML()); } ?>

The $check array holds all the allowed attributes and validation rules. Maybe this is useful for some of you. I haven't tested is yet, so tips are welcome

If you wan to provide lollipop support notification icon then make two type notification icon :

1. normal notification icon : for below lollipop version.
2. notification icon with transparent background : for lollipop and above version.

Now set appropriate icon to notification builder at run time base on OS version :

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    mBuilder.setSmallIcon(R.drawable.ic_push_notification_transperent);
} else {
    mBuilder.setSmallIcon(R.drawable.ic_push_notification);
}

In Java
Integer/Integer = Integer
Integer/Double = Double//Either of numerator or denominator must be floating point number
1/10 = 0
1.0/10 = 0.1
1/10.0 = 0.1

Just type cast either of them.

There is another type-safe alternative to specifying a base-package location as a String. See the API here, but I've also illustrated below:

@ComponentScan(basePackageClasses = {ExampleController.class, ExampleModel.class, ExmapleView.class})

Using the basePackageClasses specifier with your class references will tell Spring to scan those packages (just like the mentioned alternatives), but this method is both type-safe and adds IDE support for future refactoring -- a huge plus in my book.

Reading from the API, Spring suggests creating a no-op marker class or interface in each package you wish to scan that serves no other purpose than to be used as a reference for/by this attribute.

IMO, I don't like the marker-classes (but then again, they are pretty much just like the package-info classes) but the type safety, IDE support, and drastically reducing the number of base packages needed to include for this scan is, with out a doubt, a far better option.

I think this is the right way :

git merge --abort

git fetch --all

Then, you have two options:

git reset --hard origin/master

OR If you are on some other branch:

git reset --hard origin/<branch_name>

SELECT * 
FROM t1
JOIN t2 USING (id, date)

perhaps you'll need to use INNEER JOIN or where t2.id is not null if you want results only matching both conditions

In some cases it's very useful to change font-size with relative font sizing units. For example:

.btn {font-size: 3vw;}

Demo: http://www.bootply.com/7VN5OCVhhF

1vw is 1% of the viewport width. More info: http://www.sitepoint.com/new-css3-relative-font-size/

May you have changed password recently for you git account You could try the git push with -u option

git push -u origin branch_name_that_you_want_to_push

After executing above command it will ask for password provide your updated password

Hope it may help you

1. Select the block of code that you want indented.

2. Right-click (or, on Mac, Ctrl-click).

3. Structure → Re-indent

Use the Attribute Equals Selector

var thevalue = 'foo';
var exists = 0 != $('#select-box option[value='+thevalue+']').length;

If the option's value was set via Javascript, that will not work. In this case we can do the following:

var exists = false;
$('#select-box option').each(function(){
    if (this.value == 'bar') {
        exists = true;
        return false;
    }
});

Caveats

Here are two worthy caveats from the comments.

Either you want user to be of type User | {} or Partial<User>, or you need to redefine the User type to allow an empty object. Right now, the compiler is correctly telling you that user is not a User. – jcalz

I don't think this should be considered a proper answer because it creates an inconsistent instance of the type, undermining the whole purpose of TypeScript. In this example, the property Username is left undefined, while the type annotation is saying it can't be undefined. – Ian Liu Rodrigues

Answer

One of the design goals of TypeScript is to "strike a balance between correctness and productivity." If it will be productive for you to do this, use Type Assertions to create empty objects for typed variables.

type User = {
    Username: string;
    Email: string;
}

const user01 = {} as User;
const user02 = <User>{};

user01.Email = "[email protected]";

Here is a working example for you.

You don't give a reproducible example but your warning message tells you exactly what the problem is.

memb only has a length of 10. I'm guessing the length of dih_y2$MemberID isn't a multiple of 10. When using ==, R spits out a warning if it isn't a multiple to let you know that it's probably not doing what you're expecting it to do. == does element-wise checking for equality. I suspect what you want to do is find which of the elements of dih_y2$MemberID are also in the vector memb. To do this you would want to use the %in% operator.

dih_col <- which(dih_y2$MemeberID %in% memb)

=COUNTIFS(H5:H21000,">=100", H5:H21000,"<999")

This doesn't work on android native browser to click "hidden input (file) element":

$('a#swaswararedirectlink')[0].click();

But this works:

$("#input-file").show();
$("#input-file")[0].click();
$("#input-file").hide();

You can also use file_put_contents():

file_put_contents('ids.txt', implode("\n", $gemList) . "\n", FILE_APPEND);

myList.GroupBy(test => test.id)
      .Select(grp => grp.First());

Edit: as getting this IEnumerable<> into a List<> seems to be a mystery to many people, you can simply write:

var result = myList.GroupBy(test => test.id)
                   .Select(grp => grp.First())
                   .ToList();

But one is often better off working with the IEnumerable rather than IList as the Linq above is lazily evaluated: it doesn't actually do all of the work until the enumerable is iterated. When you call ToList it actually walks the entire enumerable forcing all of the work to be done up front. (And may take a little while if your enumerable is infinitely long.)

The flipside to this advice is that each time you enumerate such an IEnumerable the work to evaluate it has to be done afresh. So you need to decide for each case whether it is better to work with the lazily evaluated IEnumerable or to realize it into a List, Set, Dictionary or whatnot.

All you need is a <clear /> tag. Here's an example:

<configuration>
  <system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="default.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>
</configuration>

Go to your Microsoft SDKs directory. A path like this:

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6 Tools

Open the WCF Configuration Editor (Microsoft Service Configuration Editor) from that directory:

SvcConfigEditor.exe

(another option to open this tool is by navigating in Visual Studio 2017 to "Tools" > "WCF Service Configuration Editor")

Open your .config file or create a new one using the editor and navigate to Diagnostics.

There you can click the "Enable MessageLogging".

More info: https://msdn.microsoft.com/en-us/library/ms732009(v=vs.110).aspx

With the trace viewer from the same directory you can open the trace log files:

SvcTraceViewer.exe

You can also enable tracing using WMI. More info: https://msdn.microsoft.com/en-us/library/ms730064(v=vs.110).aspx

Within Excel you need to set a reference to the VB script run-time library. The relevant file is usually located at \Windows\System32\scrrun.dll

• To reference this file, load the Visual Basic Editor (ALT+F11)
• Select Tools > References from the drop-down menu
• A listbox of available references will be displayed
• Tick the check-box next to 'Microsoft Scripting Runtime'
• The full name and path of the scrrun.dll file will be displayed below the listbox
• Click on the OK button.

This can also be done directly in the code if access to the VBA object model has been enabled.

Access can be enabled by ticking the check-box Trust access to the VBA project object model found at File > Options > Trust Center > Trust Center Settings > Macro Settings

To add a reference:

Sub Add_Reference()

    Application.VBE.ActiveVBProject.References.AddFromFile "C:\Windows\System32\scrrun.dll"
'Add a reference

End Sub

To remove a reference:

Sub Remove_Reference()

Dim oReference As Object

    Set oReference = Application.VBE.ActiveVBProject.References.Item("Scripting")

    Application.VBE.ActiveVBProject.References.Remove oReference
'Remove a reference

End Sub

I think it's important to point out and to know that if the destination slice (the slice you append to) has sufficient capacity, the append will happen "in-place", by reslicing the destination (reslicing to increase its length in order to be able to accommodate the appendable elements).

This means that if the destination was created by slicing a bigger array or slice which has additional elements beyond the length of the resulting slice, they may get overwritten.

To demonstrate, see this example:

a := [10]int{1, 2}
fmt.Printf("a: %v\n", a)

x, y := a[:2], []int{3, 4}
fmt.Printf("x: %v, y: %v\n", x, y)
fmt.Printf("cap(x): %v\n", cap(x))

x = append(x, y...)
fmt.Printf("x: %v\n", x)

fmt.Printf("a: %v\n", a)

Output (try it on the Go Playground):

a: [1 2 0 0 0 0 0 0 0 0]
x: [1 2], y: [3 4]
cap(x): 10
x: [1 2 3 4]
a: [1 2 3 4 0 0 0 0 0 0]

We created a "backing" array a with length 10. Then we create the x destination slice by slicing this a array, y slice is created using the composite literal []int{3, 4}. Now when we append y to x, the result is the expected [1 2 3 4], but what may be surprising is that the backing array a also changed, because capacity of x is 10 which is sufficient to append y to it, so x is resliced which will also use the same a backing array, and append() will copy elements of y into there.

If you want to avoid this, you may use a full slice expression which has the form

a[low : high : max]

which constructs a slice and also controls the resulting slice's capacity by setting it to max - low.

See the modified example (the only difference is that we create x like this: x = a[:2:2]:

a := [10]int{1, 2}
fmt.Printf("a: %v\n", a)

x, y := a[:2:2], []int{3, 4}
fmt.Printf("x: %v, y: %v\n", x, y)
fmt.Printf("cap(x): %v\n", cap(x))

x = append(x, y...)
fmt.Printf("x: %v\n", x)

fmt.Printf("a: %v\n", a)

Output (try it on the Go Playground)

a: [1 2 0 0 0 0 0 0 0 0]
x: [1 2], y: [3 4]
cap(x): 2
x: [1 2 3 4]
a: [1 2 0 0 0 0 0 0 0 0]

As you can see, we get the same x result but the backing array a did not change, because capacity of x was "only" 2 (thanks to the full slice expression a[:2:2]). So to do the append, a new backing array is allocated that can store the elements of both x and y, which is distinct from a.

Yes, you can achieve this by using the following commands:

sqlite> .headers on
sqlite> .mode column

The result of a select on your table will then look like:

id          foo         bar         age         street      address
----------  ----------  ----------  ----------  ----------  ----------
1           val1        val2        val3        val4        val5
2           val6        val7        val8        val9        val10

my quick answer with basic java arithmetic calculation is this:

First consider the following values:

1 Minute = 60 Seconds
1 Hour = 3600 Seconds ( 60 * 60 )
1 Day = 86400 Second ( 24 * 3600 )

1. First divide the input by 86400, if you you can get a number greater than 0 , this is the number of days. 2.Again divide the remained number you get from the first calculation by 3600, this will give you the number of hours
2. Then divide the remainder of your second calculation by 60 which is the number of Minutes
3. Finally the remained number from your third calculation is the number of seconds

the code snippet is as follows:

int input=500000;
int numberOfDays;
int numberOfHours;
int numberOfMinutes;
int numberOfSeconds;

numberOfDays = input / 86400;
numberOfHours = (input % 86400 ) / 3600 ;
numberOfMinutes = ((input % 86400 ) % 3600 ) / 60 
numberOfSeconds = ((input % 86400 ) % 3600 ) % 60  ;

I hope to be helpful to you.

You can call it three ways - with parameters, with DEFAULT and via EXECUTE

SET NOCOUNT ON;

DECLARE
@Table  SYSNAME = 'YourTable',
@Schema SYSNAME = 'dbo',
@Rows   INT;

SELECT dbo.TableRowCount( @Table, @Schema )

SELECT dbo.TableRowCount( @Table, DEFAULT )

EXECUTE @Rows = dbo.TableRowCount @Table

SELECT @Rows

Please post your Model Class.

To check the errors in your ModelState use the following code:

var errors = ModelState
    .Where(x => x.Value.Errors.Count > 0)
    .Select(x => new { x.Key, x.Value.Errors })
    .ToArray();

OR: You can also use

var errors = ModelState.Values.SelectMany(v => v.Errors);

Place a break point at the above line and see what are the errors in your ModelState.

{ thetop : 10 } is a valid object literal. The code will create an object with a property named thetop that has a value of 10. Both the following are the same:

obj = { thetop : 10 };
obj = { "thetop" : 10 };

In ES5 and earlier, you cannot use a variable as a property name inside an object literal. Your only option is to do the following:

var thetop = "top";

// create the object literal
var aniArgs = {};

// Assign the variable property name with a value of 10
aniArgs[thetop] = 10; 

// Pass the resulting object to the animate method
<something>.stop().animate(
    aniArgs, 10  
);  

ES6 defines ComputedPropertyName as part of the grammar for object literals, which allows you to write the code like this:

var thetop = "top",
    obj = { [thetop]: 10 };

console.log(obj.top); // -> 10

You can use this new syntax in the latest versions of each mainstream browser.

The role you have created is not allowed to log in. You have to give the role permission to log in.

One way to do this is to log in as the postgres user and update the role:

psql -U postgres

Once you are logged in, type:

ALTER ROLE "asunotest" WITH LOGIN;

Here's the documentation http://www.postgresql.org/docs/9.0/static/sql-alterrole.html

public const int NUMBER = 9;

You'd need to put it in a class somewhere, and the usage would be ClassName.NUMBER

I had the same problem even though I had:

• a freshly downloaded JDK 1.8.0

• JAVA_HOME is set

• java -version on command line reports 1.8

• Java in control panel is set to 1.8

• downloaded Eclipse Mars

Eclipse only let me choose a compiler compliance level op to 1.7 in the compiler preferences, even though my installed JRE is 1.8.0. I also couldn't see a 1.8 in the Execution Environments underneath Installed JREs, only a JavaSE-1.7 (which I haven't even got installed!). When I clicked on that, it shows "jdk1.8.0" as a compatible JRE, so I selected that, but still no change.

Then I unzipped Eclipse Mars into a brand new directory, created a new project, and now I can select 1.8, hurrah! That greatly reduced the "Duplicate methods named spliterator..." errors I was getting when compiling my code under Java 1.8, however, there is still one left:

Duplicate default methods named spliterator with the parameters () and () are inherited from the types List and Set.

However, that's likely because I'm extending AbstractList and implementing Set, so I've fixed that for now by removing the implements Set because it doesn't really add anything in my case (other than signifying that my collection has only unique elements)

git merge --abort

Abort the current conflict resolution process, and try to reconstruct the pre-merge state.

If there were uncommitted worktree changes present when the merge started, git merge --abort will in some cases be unable to reconstruct these changes. It is therefore recommended to always commit or stash your changes before running git merge.

git merge --abort is equivalent to git reset --merge when MERGE_HEAD is present.

http://www.git-scm.com/docs/git-merge

It doesn't make a lot of sense, the original GAC was already quite capable of storing different versions of assemblies. And there's little reason to assume a program will ever accidentally reference the wrong assembly, all the .NET 4 assemblies got the [AssemblyVersion] bumped up to 4.0.0.0. The new in-process side-by-side feature should not change this.

My guess: there were already too many .NET projects out there that broke the "never reference anything in the GAC directly" rule. I've seen it done on this site several times.

Only one way to avoid breaking those projects: move the GAC. Back-compat is sacred at Microsoft.

Check if you are using Docker Machine :)

Run docker-machine env default should do the trick.

Because according to documentation:

Docker Machine is a tool that lets you install Docker Engine on virtual hosts, and manage the hosts with docker-machine commands. You can use Machine to create Docker hosts on your local Mac or Windows box, on your company network, in your data center, or on cloud providers like AWS or Digital Ocean.

Using docker-machine commands, you can start, inspect, stop, and restart a managed host, upgrade the Docker client and daemon, and configure a Docker client to talk to your host.

Point the Machine CLI at a running, managed host, and you can run docker commands directly on that host. For example, run docker-machine env default to point to a host called default, follow on-screen instructions to complete env setup, and run docker ps, docker run hello-world, and so forth.

https://docs.docker.com/machine/overview/

It's 'Dirty' way of using memory addresses. When you return an address (pointer) you don't know whether it belongs to local scope of a function. It's just an address. Now that you invoked the 'foo' function, that address (memory location) of 'a' was already allocated there in the (safely, for now at least) addressable memory of your application (process). After the 'foo' function returned, the address of 'a' can be considered 'dirty' but it's there, not cleaned up, nor disturbed/modified by expressions in other part of program (in this specific case at least). A C/C++ compiler doesn't stop you from such 'dirty' access (might warn you though, if you care). You can safely use (update) any memory location that is in the data segment of your program instance (process) unless you protect the address by some means.

That's called onload. DOM ready was actually created for the exact reason that onload waited on images. ( Answer taken from Matchu on a simmilar question a while ago. )

window.onload = function () { alert("It's loaded!") }

onload waits for all resources that are part of the document.

Click me, you know you want to!

here is an easy way to use join.

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

Another way is to use the subplots function and pass the width ratio with gridspec_kw:

import numpy as np
import matplotlib.pyplot as plt 

# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# plot it
f, (a0, a1) = plt.subplots(1, 2, gridspec_kw={'width_ratios': [3, 1]})
a0.plot(x, y)
a1.plot(y, x)

f.tight_layout()
f.savefig('grid_figure.pdf')

git show-ref --heads

The answer by @gertvdijk is the most concise and elegant, but I wanted to leave this here because it helped me grasp the idea that refs/heads/* are equivalent to local branches.

Most of the time the refs/heads/master ref is a file at .git/refs/heads/master that contains a git commit hash that points to the git object that represents the current state of your local master branch, so each file under .git/refs/heads/* represents a local branch.

The existing answers are true as of C# <=7.2. However, there is a C# language feature request (tied to a corefx feature request) to allow the following;

public class MyGeneric<TEnum> where TEnum : System.Enum
{ }

At time of writing, the feature is "In discussion" at the Language Development Meetings.

EDIT

As per nawfal's info, this is being introduced in C# 7.3.

EDIT 2

This is now in C# 7.3 forward (release notes)

Sample;

public static Dictionary<int, string> EnumNamedValues<T>()
    where T : System.Enum
{
    var result = new Dictionary<int, string>();
    var values = Enum.GetValues(typeof(T));

    foreach (int item in values)
        result.Add(item, Enum.GetName(typeof(T), item));
    return result;
}

You can try this code:

public void itemClicked(View v) {
 //code to check if this checkbox is checked!
 if(((Checkbox)v).isChecked()){
   // code inside if
 }
}

Also see PEP 263 if you are using a non-ascii characterset

Abstract

This PEP proposes to introduce a syntax to declare the encoding of a Python source file. The encoding information is then used by the Python parser to interpret the file using the given encoding. Most notably this enhances the interpretation of Unicode literals in the source code and makes it possible to write Unicode literals using e.g. UTF-8 directly in an Unicode aware editor.

Problem

In Python 2.1, Unicode literals can only be written using the Latin-1 based encoding "unicode-escape". This makes the programming environment rather unfriendly to Python users who live and work in non-Latin-1 locales such as many of the Asian countries. Programmers can write their 8-bit strings using the favorite encoding, but are bound to the "unicode-escape" encoding for Unicode literals.

Proposed Solution

I propose to make the Python source code encoding both visible and changeable on a per-source file basis by using a special comment at the top of the file to declare the encoding.

To make Python aware of this encoding declaration a number of concept changes are necessary with respect to the handling of Python source code data.

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given.

To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as:

      # coding=<encoding name>

or (using formats recognized by popular editors)

      #!/usr/bin/python
      # -*- coding: <encoding name> -*-

or

      #!/usr/bin/python
      # vim: set fileencoding=<encoding name> :

...

You can define your own custom MarshalJSON and UnmarshalJSON methods and intentionally control what should be included, ex:

package main

import (
    "fmt"
    "encoding/json"
)

type User struct {
    name string
}

func (u *User) MarshalJSON() ([]byte, error) {
    return json.Marshal(&struct {
        Name     string `json:"name"`
    }{
        Name:     "customized" + u.name,
    })
}

func main() {
    user := &User{name: "Frank"}
    b, err := json.Marshal(user)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(string(b))
}

I'm not fully sure that this is what you're looking for, but if your question is how to read an integer using <stdio.h>, then the proper syntax is

int myInt;
scanf("%d", &myInt);

You'll need to do a lot of error-handling to ensure that this works correctly, of course, but this should be a good start. In particular, you'll need to handle the cases where

1. The stdin file is closed or broken, so you get nothing at all.
2. The user enters something invalid.

To check for this, you can capture the return code from scanf like this:

int result = scanf("%d", &myInt);

If stdin encounters an error while reading, result will be EOF, and you can check for errors like this:

int myInt;
int result = scanf("%d", &myInt);

if (result == EOF) {
    /* ... you're not going to get any input ... */
}

If, on the other hand, the user enters something invalid, like a garbage text string, then you need to read characters out of stdin until you consume all the offending input. You can do this as follows, using the fact that scanf returns 0 if nothing was read:

int myInt;
int result = scanf("%d", &myInt);

if (result == EOF) {
    /* ... you're not going to get any input ... */
}
if (result == 0) {
    while (fgetc(stdin) != '\n') // Read until a newline is found
        ;
}

Hope this helps!

EDIT: In response to the more detailed question, here's a more appropriate answer. :-)

The problem with this code is that when you write

printf("got the number: %d", scanf("%d", &x));

This is printing the return code from scanf, which is EOF on a stream error, 0 if nothing was read, and 1 otherwise. This means that, in particular, if you enter an integer, this will always print 1 because you're printing the status code from scanf, not the number you read.

To fix this, change this to

int x;
scanf("%d", &x);
/* ... error checking as above ... */
printf("got the number: %d", x);

Hope this helps!

    public class HomeController : Controller  
    {  
        public ActionResult Index()  
        {  
            ViewBag.TempValue = "Index Action called at HomeController";  
            return View();

            return View();

The code is initially invoking an Index action that in turn returns two Index views and at the View level it calls the ChildAction named “ChildAction”.

In my case I was using the maven-dependency-plugin so in order to resolve the issue I had to add the following property:

  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

The other features of CodeLens like: Show Bugs, Show Test Status, etc (other than Show Reference) might be useful.

However, if the only way to disable Show References is to disable CodeLens altogether.

Then, I guess I could do just that.

Furthermore, I would do like I always have, 'right-click on a member and choose Find all References or Ctrl+K, R'

If I wanted to know what references the member -- I too like not having any extra information crammed into my code, like extra white-space.

In short, uncheck Codelens...

For efficiency's sake you want to only hit the data once, as Harper does. However you don't want to use rank() because it will give you ties and further you want to group by language rather than order by language. From there you want add an order by clause to distinguish between rows, but you don't want to actually sort the data. To achieve this I would use "order by null" E.g.

count(*) over (group by language order by null)

To see a frequency count for column two (for example):

awk -F '\t' '{print $2}' * | sort | uniq -c | sort -nr

fileA.txt

z    z    a
a    b    c
w    d    e

fileB.txt

t    r    e
z    d    a
a    g    c

fileC.txt

z    r    a
v    d    c
a    m    c

Result:

  3 d
  2 r
  1 z
  1 m
  1 g
  1 b

Use Activity.getWindow() to get the window of your activity; use Window.addFlags() to add whichever of the following flags in WindowManager.LayoutParams that you desire:

• FLAG_DISMISS_KEYGUARD

• FLAG_SHOW_WHEN_LOCKED

• FLAG_TURN_SCREEN_ON

If you see those characters you probably just didn’t specify the character encoding properly. Because those characters are the result when an UTF-8 multi-byte string is interpreted with a single-byte encoding like ISO 8859-1 or Windows-1252.

In this case ë could be encoded with 0xC3 0xAB that represents the Unicode character ë (U+00EB) in UTF-8.

For Windows 7

You may specify an alternate path for \data\db with the dbpath setting for mongod.exe,

as in the following example:

c:\mongodb\bin\mongod.exe --dbpath c:\mongodb\data\db

or

you can set dbpath through Configuration File.

I know this answer is not 100% related to the question, but it might help someone.

If you want to disable the browser cache for the entire ASP.NET MVC Website, but you only want to do this TEMPORARILY, then it is better to disable the cache in your browser.

You map your dispatcher on *.do:

<servlet-mapping>
   <servlet-name>Dispatcher</servlet-name>
   <url-pattern>*.do</url-pattern>
</servlet-mapping>

but your controller is mapped on an url without .do:

@RequestMapping("/editPresPage")

Try changing this to:

@RequestMapping("/editPresPage.do")

Well you can use the setup() method to declare the different values of your env. variables in constants. Then use these constants in the tests methods used to test the different scenario.

I have tried all the above but nothing was working. Later on, I ran my command prompt as an admin and retried all the stages i.e. staging-> committing-> remote add -> pushing. It worked like a magic. The changes were reflected in the desired remote repository.

If your web server supports Serlvet 3.0 spec, like tomcat 7.0+, you can use below in web.xml as:

<session-config>
  <cookie-config>
     <http-only>true</http-only>        
     <secure>true</secure>        
  </cookie-config>
</session-config>

As mentioned in docs:

HttpOnly: Specifies whether any session tracking cookies created by this web application will be marked as HttpOnly

Secure: Specifies whether any session tracking cookies created by this web application will be marked as secure even if the request that initiated the corresponding session is using plain HTTP instead of HTTPS

Please refer to how to set httponly and session cookie for java web application

In Lumen's .env file, specify the timezones. For India, it would be like:

APP_TIMEZONE = 'Asia/Calcutta'
DB_TIMEZONE = '+05:30'

If someone finds this question like me, here are my performance tests of proposed methods:

Python 2.7.8

In [1]: %timeit ([1]*1000000).insert(0, 0)
100 loops, best of 3: 4.62 ms per loop

In [2]: %timeit ([1]*1000000)[0:0] = [0]
100 loops, best of 3: 4.55 ms per loop

In [3]: %timeit [0] + [1]*1000000
100 loops, best of 3: 8.04 ms per loop

As you can see, insert and slice assignment are as almost twice as fast than explicit adding and are very close in results. As Raymond Hettinger noted insert is more common option and I, personally prefer this way to prepend to list.

You could define a mapping of air pressure to servo angle, for example:

def calc_angle(pressure, min_p=1000, max_p=1200):     return 360 * ((pressure - min_p) / float(max_p - min_p))  angle = calc_angle(pressure) 

This will linearly convert pressure values between min_p and max_p to angles between 0 and 360 (you could include min_a and max_a to constrain the angle, too).

To pick a data structure, I wouldn't use a list but you could look up values in a dictionary:

d = {1000:0, 1001: 1.8, ...}  angle = d[pressure] 

but this would be rather time-consuming to type out!

I had a problem with sending a request with multiple parameters.

I've solved it by sending a class, with the old parameters as properties.

<form action="http://localhost:12345/api/controller/method" method="post">
    <input type="hidden" name="name1" value="value1" />
    <input type="hidden" name="name2" value="value2" />
    <input type="submit" name="submit" value="Submit" />
</form>

Model class:

public class Model {
    public string Name1 { get; set; }
    public string Name2 { get; set; }
}

Controller:

public void method(Model m) {
    string name = m.Name1;
}

You just download commons-logging-1.1.2.jar and then copy this file in to libs

finally, it works.

Currently, the link dlptest is working fine.

The files will only be stored for 30 minutes before being deleted.

I believe Double.NaN might be able to cover this. That is the only 'null' value double contains.

def time_to_sec(time):
    sep = ','
    rest = time.split(sep, 1)[0]
    splitted = rest.split(":")
    emel = len(splitted) - 1
    i = 0
    summa = 0
    for numb in splitted:
        szor = 60 ** (emel - i)
        i += 1
        summa += int(numb) * szor
    return summa

In the aspx page load event, add an onkeypress to the box.

this.TextBox1.Attributes.Add(
    "onkeypress", "button_click(this,'" + this.Button1.ClientID + "')");

Then add this javascript to evaluate the key press, and if it is "enter," click the right button.

<script>
    function button_click(objTextBox,objBtnID)
    {
        if(window.event.keyCode==13)
        {
            document.getElementById(objBtnID).focus();
            document.getElementById(objBtnID).click();
        }
    }
</script>

What you are trying to do is impossible; your current shell is running under your regular user ID (i.e. without root the access sudo would give you), and there is no way to grant it root access. What sudo does is create a new *sub*process that runs as root. The subprocess could be just a regular program (e.g. sudo cp ... runs the cp program in a root process) or it could be a root subshell, but it cannot be the current shell.

(It's actually even more impossible than that, because the sudo command itself is executed as a subprocess of the current shell -- meaning that in a sense it's already too late for it to do anything in the "current shell", because that's not where it executes.)

TLPD ("too long path directory") is the program that saved me. Very easy to use:

https://sourceforge.net/projects/tlpd/

This gives you last used row in a specified column.

Optionally you can specify worksheet, else it will takes active sheet.

Function shtRowCount(colm As Integer, Optional ws As Worksheet) As Long

    If ws Is Nothing Then Set ws = ActiveSheet

    If ws.Cells(Rows.Count, colm) <> "" Then
        shtRowCount = ws.Cells(Rows.Count, colm).Row
        Exit Function
    End If

    shtRowCount = ws.Cells(Rows.Count, colm).Row

    If shtRowCount = 1 Then
        If ws.Cells(1, colm) = "" Then
            shtRowCount = 0
        Else
            shtRowCount = 1
        End If
    End If

End Function

Sub test()

    Dim lgLastRow As Long
    lgLastRow = shtRowCount(2) 'Column B

End Sub

I am not familiar with this plugin, but we quite successfully use Bitbucket and Jenkins together, however we poll for changes instead of having them pushed from BitBucket (due to the fact our build server is hidden behind a company firewall). This approach may work for you if you are still having problems with the current approach.

This document on Setting up SSH for Git & Mercurial on Linux covers the details of what you need to do to be able to communicate between your build server and Bitbucket over SSH. Once this is done, with the Git Plugin installed, go to your build configuration and select 'Git' under Source Code Management, and enter the ssh URL of your repository as the repository URL. Finally, in the Build Triggers section, select Poll SCM and set the poll frequency to whatever you require.

i've mandained some similar page (classic asp...)

my approach was to use Q promise directly on the popup.

For example my problem was that the popup i wanted to print close itself too fast ... and the print previw was empty, i solved this way :

Caller :

var popup = window.open("index.asp","popupwindow","width=800,height=500,left=200,top=5,scrollbars,toolbar=0,resizable");

Popup (at the end of the page):

<script src="/Scripts/jquery-1.9.1.min.js"></script>
<script src="/Scripts/q.min.js"></script>
<script type="text/javascript">
    Q(window.print()).then(function () {window.close();});
</script>

I think that your "parent lock" could be solved in a similar way

i would try :

var w = whatever;
Q(
  // fill your popup
).then(function () {
 w.print();
}).then(function () {
 w.close();
}); 

that makes "the print" and "the close" async... so the parent will be immediately "unlocked"

That works fine. See this fiddle: http://jsfiddle.net/kveAL/

It is possible that you need to declare your jQuery in a $(document).ready() handler?

Also, might you have two elements that have the same ID?

The details in the comments section above did not work for me (VS 2013) when trying to copy the output dll from one C++ project to the release and debug folder of another C# project within the same solution.

I had to add the following post build-action (right click on the project that has a .dll output) then properties -> configuration properties -> build events -> post-build event -> command line

now I added these two lines to copy the output dll into the two folders:

xcopy /y $(TargetPath) $(SolutionDir)aeiscontroller\bin\Release
xcopy /y $(TargetPath) $(SolutionDir)aeiscontroller\bin\Debug

I had the same issue and the following seemed to have addressed the issue.

a) Updated to latest version 1.3.5 and re-enabled all the diagnosis settings.

I was still getting the messages

b) Added the vendor folder with the dependent libraries to the workspace

This seems to have solved the problem.

Although everyone answer "No" and I know that "No" is the right answer but if you really need to get local variables of a function there is a restricted way.

Consider this function:

var f = function() {
    var x = 0;
    console.log(x);
};

You can convert your function to a string:

var s = f + '';

You will get source of function as a string

'function () {\nvar x = 0;\nconsole.log(x);\n}'

Now you can use a parser like esprima to parse function code and find local variable declarations.

var s = 'function () {\nvar x = 0;\nconsole.log(x);\n}';
s = s.slice(12); // to remove "function () "
var esprima = require('esprima');
var result = esprima.parse(s);

and find objects with:

obj.type == "VariableDeclaration"

in the result (I have removed console.log(x) below):

{
    "type": "Program",
    "body": [
        {
            "type": "VariableDeclaration",
            "declarations": [
                {
                    "type": "VariableDeclarator",
                    "id": {
                        "type": "Identifier",
                        "name": "x"
                    },
                    "init": {
                        "type": "Literal",
                        "value": 0,
                        "raw": "0"
                    }
                }
            ],
            "kind": "var"
        }
    ]
}

I have tested this in Chrome, Firefox and Node.

But the problem with this method is that you just have the variables defined in the function itself. For example for this one:

var g = function() {
    var y = 0;
    var f = function() {
        var x = 0;
        console.log(x);
    };
}

you just have access to the x and not y. But still you can use chains of caller (arguments.callee.caller.caller.caller) in a loop to find local variables of caller functions. If you have all local variable names so you have scope variables. With the variable names you have access to values with a simple eval.

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

You can call qApp.exit();. I always use that and never had a problem with it.

If you application is a command line application, you might indeed want to return an exit code. It's completely up to you what the code is.

The accepted answer didn't meet my needs (it allows underscores, doesn't handle dashes at the beginning and end, etc.), and the other answers had other issues that didn't suit my use case, so here's the slugify function I came up with:

function slugify(string) {
    return string.trim() // Remove surrounding whitespace.
    .toLowerCase() // Lowercase.
    .replace(/[^a-z0-9]+/g,'-') // Find everything that is not a lowercase letter or number, one or more times, globally, and replace it with a dash.
    .replace(/^-+/, '') // Remove all dashes from the beginning of the string.
    .replace(/-+$/, ''); // Remove all dashes from the end of the string.
}

This will turn ' foo!!!BAR_-_-_baz-' (note the space at the beginning) into foo-bar-baz.

More correct create DTO for API queries, for example entityDTO:

1. Default response OK with list of entities:

@GetMapping(produces=MediaType.APPLICATION_JSON_VALUE)
@ResponseStatus(HttpStatus.OK)
public List<EntityDto> getAll() {
    return entityService.getAllEntities();
}

But if you need return different Map parameters you can use next two examples
2. For return one parameter like map:

@GetMapping(produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> getOneParameterMap() {
    return ResponseEntity.status(HttpStatus.CREATED).body(
            Collections.singletonMap("key", "value"));
}

3. And if you need return map of some parameters(since Java 9):

@GetMapping(produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> getSomeParameters() {
    return ResponseEntity.status(HttpStatus.OK).body(Map.of(
            "key-1", "value-1",
            "key-2", "value-2",
            "key-3", "value-3"));
}

Set sound to notification channel

        Uri alarmUri = Uri.fromFile(new File(<path>));

        AudioAttributes attributes = new AudioAttributes.Builder()
                .setUsage(AudioAttributes.USAGE_ALARM)
                .build();

        channel.setSound(alarmUri, attributes);

Are you sure you are on the local an-other-branch when you merge?

git fetch origin an-other-branch
git checkout an-other-branch
git merge origin/an-other-branch

The other explanation:

all the changes from the branch you’re trying to merge have already been merged to the branch you’re currently on.
More specifically it means that the branch you’re trying to merge is a parent of your current branch

if you're ahead of the remote repo by one commit, it's the remote repo that's out of date, not you.

But in your case, if git pull works, that just means you are not on the right branch.

You can use json_decode() to convert a json string to a PHP object/array.

Eg.

Input:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));
var_dump(json_decode($json, true));

Output:

object(stdClass)#1 (5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

array(5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

Few Points to remember:

• json_decode requires the string to be a valid json else it will return NULL.
• In the event of a failure to decode, json_last_error() can be used to determine the exact nature of the error.
• Make sure you pass in utf8 content, or json_decode may error out and just return a NULL value.

collections.Counter is new in python 2.7:

Python 2.5.4 (r254:67916, May 31 2010, 15:03:39) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
a = [1,2,3,2,1,5,6,5,5,5]
import collections
print [x for x, y in collections.Counter(a).items() if y > 1]
Type "help", "copyright", "credits" or "license" for more information.
  File "", line 1, in 
AttributeError: 'module' object has no attribute 'Counter'

In an earlier version you can use a conventional dict instead:

a = [1,2,3,2,1,5,6,5,5,5]
d = {}
for elem in a:
    if elem in d:
        d[elem] += 1
    else:
        d[elem] = 1

print [x for x, y in d.items() if y > 1]

Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax() method. Or if you wanted to do it using plain javascript, here's a tutorial.

Reporting to an external website/database

I wanted a way to simply and automatically report errors (since users often don't) from our applications. The easiest solution I could come up with was a public URL - a web page which could take input and store it to a database - that is sent data upon an application error. (The database could then be checked by a dev or a script to know if there are new errors.)

I wrote the web page in PHP and created a mysql database, user, and table to store the data. I decided on four user variables, an id, and a timestamp. The possible variables (either included in the URL or as POST data) are:

• app (application name)
• msg (message - e.g. Exception occurred ...)
• dev (developer - e.g. Pat)
• src (source - this would come from a variable pertaining to the machine on which the app was running, e.g. Environment.MachineName or some such)
• log (a log file or verbose message)

(All of the variables are optional, but nothing is reported if none of them are set - so if you just visit the website URL nothing is sent to the db.)

To send the data to the URL, I used NLog's WebService target. (Note, I had a few problems with this target at first. It wasn't until I looked at the source that I figured out that my url could not end with a /.)

All in all, it's not a bad system for keeping tabs on external apps. (Of course, the polite thing to do is to inform your users that you will be reporting possibly sensitive data and to give them a way to opt in/out.)

MySQL stuff

(The db user has only INSERT privileges on this one table in its own database.)

CREATE TABLE `reports` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `ts` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
  `applicationName` text,
  `message` text,
  `developer` text,
  `source` text,
  `logData` longtext,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COMMENT='storage place for reports from external applications'

            ':log' => $log

//print_r($dbData); // For debugging only! This could allow XSS attacks.
if(isEmpty($dbData)) die("No data provided");

try {
$db = new PDO("mysql:host=$host;dbname=reporting", "reporter", $pass, array(

Note: there may be some issues with the size of the log file, but I haven't figured out a simple way to truncate it (e.g. a la *nix's tail command).

I had to do this and used subprocess.

import subprocess

subprocess.run("python3 script1.py & python3 script2.py", shell=True)

ERROR 2005 (HY000): Unknown MySQL server host 'localhost' (0)

modify list of host names for your system:

C:\Windows\System32\drivers\etc\hosts

Make sure that you have the following entry:

127.0.0.1 localhost
In my case that entry was 0.0.0.0 localhost which caussed all problem

(you may need to change modify permission to modify this file)

This performs DNS resolution of host “localhost” to the IP address 127.0.0.1.

You can define a Error.prototype.toJSON to retrieve a plain Object representing the Error:

if (!('toJSON' in Error.prototype))
Object.defineProperty(Error.prototype, 'toJSON', {
    value: function () {
        var alt = {};

        Object.getOwnPropertyNames(this).forEach(function (key) {
            alt[key] = this[key];
        }, this);

        return alt;
    },
    configurable: true,
    writable: true
});

var error = new Error('testing');
error.detail = 'foo bar';

console.log(JSON.stringify(error));
// {"message":"testing","detail":"foo bar"}

Using Object.defineProperty() adds toJSON without it being an enumerable property itself.

Regarding modifying Error.prototype, while toJSON() may not be defined for Errors specifically, the method is still standardized for objects in general (ref: step 3). So, the risk of collisions or conflicts is minimal.

Though, to still avoid it completely, JSON.stringify()'s replacer parameter can be used instead:

function replaceErrors(key, value) {
    if (value instanceof Error) {
        var error = {};

        Object.getOwnPropertyNames(value).forEach(function (key) {
            error[key] = value[key];
        });

        return error;
    }

    return value;
}

var error = new Error('testing');
error.detail = 'foo bar';

console.log(JSON.stringify(error, replaceErrors));

This is what worked for me, I added another line after the 127.0.0.1 ip to specify the exact local network ip address (not the public ip address) of the device I wanted to use. In my case my Samsung Galaxy S3

As suggested by Bangptit edit the httpd.conf file (x being the version numbers): C:\wamp\bin\apache\Apache2.x.x\conf\httpd.conf

Search for the onlineoffline tag and add the ip of your phone (I found my phones ip address in my routers configuration pages):

onlineoffline tag - don't remove

 Order Deny,Allow
 Deny from all
 Allow from 127.0.0.1

my phones ip in the line below

 Allow from 192.168.1.65 
 Allow from ::1
 Allow from localhost

One could extend this to include an entire sub domain too for e.g. 192.168.1.0/24 etc

Go to the language settings in the Control Panel, then Format Options, select a locale and see the actual date format for the chosen locale used by Windows by default. Yes, that timestamp format is locale-sensitive. Excel uses those formats when parsing CSV.

Even further, if the locale uses characters beyond ASCII, you'll have to emit CSV in the corresponding pre-Unicode Windows "ANSI" codepage, e.g. CP1251. Excel won't accept UTF-8.

You reference a Linux distribution, so you need to install the readline development libraries

On Debian based platforms, like Ubuntu, you can run:

sudo apt-get install libreadline-dev 

and that should install the correct headers in the correct places,.

If you use a platform with yum, like SUSE, then the command should be:

yum install readline-devel

try this:

$('.chzn-choices input').autocomplete({
  source: function( request, response ) {
    $.ajax({
      url: "/change/name/autocomplete/"+request.term+"/",
      dataType: "json",
      beforeSend: function(){$('ul.chzn-results').empty();},
      success: function( data ) {
        response( $.map( data, function( item ) {
          $('ul.chzn-results').append('<li class="active-result">' + item.name + '</li>');
        }));
      }
    });
  }
});

You can use ANSI colour codes.

use these functions.

enum c_color{BLACK=30,RED=31,GREEN=32,YELLOW=33,BLUE=34,MAGENTA=35,CYAN=36,WHITE=37};
enum c_decoration{NORMAL=0,BOLD=1,FAINT=2,ITALIC=3,UNDERLINE=4,RIVERCED=26,FRAMED=51};
void pr(const string str,c_color color,c_decoration decoration=c_decoration::NORMAL){
  cout<<"\033["<<decoration<<";"<<color<<"m"<<str<<"\033[0m";
}

void prl(const string str,c_color color,c_decoration decoration=c_decoration::NORMAL){
   cout<<"\033["<<decoration<<";"<<color<<"m"<<str<<"\033[0m"<<endl;
}

open build.gradle and update dependencies

    classpath 'com.android.tools.build:gradle:4.0.1'

If you have issue with writing into an existing xls file because it is already created you need to put checking part like below:

PATH='filename.xlsx'
if os.path.isfile(PATH):
    print "File exists and will be overwrite NOW"
else:
    print "The file is missing, new one is created"

... and here part with the data you want to add

After :

sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0) 
    error("ERROR opening socket");

You can add (with standard C99 compound literal support) :

if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &(int){1}, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

Or :

int enable = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &enable, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

If the column has a 0 value, you are fine, my guess is that you have a problem with a Null value, in that case you would need to use IsNull(Column, 0) to ensure it is always 0 at minimum.

There are two ways:

The best way is to remove the <p> altogether. It is acting according to specification when it adds space.

Alternately, use CSS to style the <p>. Something like:

ul li p {
    padding: 0;
    margin: 0;
    display: inline;
}

The part about not being able to use the Back button is a common misinterpretation. window.location.replace(URL) throws out the top ONE entry from the page history list, by overwriting it with the new entry, so the user can't easily go Back to that ONE particular webpage. The function does NOT wipe out the entire page history list, nor does it make the Back button completely non-functional.

(NO function nor combination of parameters that I know of can change or overwrite history list entries that you don't own absolutely for certain - browsers generally impelement this security limitation by simply not even defining any operation that might at all affect any entry other than the top one in the page history list. I shudder to think what sorts of dastardly things malware might do if such a function existed.)

If you really want to make the Back button non-functional (probably not "user friendly": think again if that's really what you want to do), "open" a brand new window. (You can "open" a popup that doesn't even have a "Back" button too ...but popups aren't very popular these days:-) If you want to keep your page showing no matter what the user does (again the "user friendliness" is questionable), set up a window.onunload handler that just reloads your page all over again clear from the very beginning every time.

One way

// join type can be inner, left, right, fullouter
val mergedDf = df1.join(df2, Seq("keyCol"), "inner")
// keyCol can be multiple column names seperated by comma
val mergedDf = df1.join(df2, Seq("keyCol1", "keyCol2"), "left")

Another way

import spark.implicits._ 
val mergedDf = df1.as("d1").join(df2.as("d2"), ($"d1.colName" === $"d2.colName"))
// to select specific columns as output
val mergedDf = df1.as("d1").join(df2.as("d2"), ($"d1.colName" === $"d2.colName")).select($"d1.*", $"d2.anotherColName")

Yes you can do this without absolute positioning and without using tables (which screw with markup and such).

DEMO
This is tested to work on IE>7, chrome, FF & is a really easy thing to add to your existing layout.

<div id="container">
    Some content you don't want affected by the "bottom floating" div
    <div>supports not just text</div>

    <div class="foot">
        Some other content you want kept to the bottom
        <div>this is in a div</div>
    </div>
</div>

#container {
    height:100%;
    border-collapse:collapse;
    display : table;
}

.foot {
    display : table-row;
    vertical-align : bottom;
    height : 1px;
}

It effectively does what float:bottom would, even accounting for the issue pointed out in @Rick Reilly's answer!

All above answers didn't work for me. My Eclipse mars is x64 but I need to set registry dll to x86 for another software.

At the end I put -vm argument at the end of shortcut and this did the trick.

D:\mars\eclipse\eclipse.exe -vm "C:\Program Files\Java\jre7\bin\server\jvm.dll"

According to this doc jvm.dll also work for some cases.

Try:

SELECT * 
FROM eventList 
WHERE  `date` BETWEEN FROM_UNIXTIME(1364256001) AND FROM_UNIXTIME(1364342399)

Or

SELECT * 
FROM eventList WHERE  `date` 
BETWEEN '2013-03-26 00:00:01' AND '2013-03-26 23:59:59'

Initialize it first

MainActivity mActivity= new MainActivity();

Then you can continue

mActivity.startChronometer();

Download http://download.cnet.com/Free-Desktop-Timer/3000-2350_4-75415517.html

Then add a button or something on the form and inside its event, just open this app ie:

{

Process.Start(@"C:\Program Files (x86)\Free Desktop Timer\DesktopTimer");

}

Both are models of an object that you have some means of controlling inputs to and observing outputs from.

The key difference is that:

• With an emulator, you want the output exactly match what the object you are emulating would produce.
• With a simulator, you want certain properties of your output to be similar to what the object would produce.

Let me give an example -- suppose you want to do some system testing to see how adding a new sensor (like a thermometer) to a system would affect the system. You know that the thermometer sends a message 8 time a second containing its measurement.

Simulation -- if you do not have the thermometer yet, but you want to test that this message rate will not overload you system, you can simulate the sensor by attaching a unit that sends a random number 8 times a second. You can run any test that does not rely on the actual value the sensor sends.

Emulation -- suppose you have a very expensive thermometer that measures to 0.001 C, and you want to see if you can get by with a cheaper thermometer that only measures to the nearest 0.5 C. You can emulate the cheaper thermometer using an expensive thermometer and then rounding the reading to the nearest 0.5 C and running tests that rely on the temperature values.

Note that simulations can also be used for forecasting or predicting behavior. Finite element analysis simulations are used in many applications, including weather prediction and virtual wind tunnels.

The definitions of the terms:

• emulation -- surpass or exactly match
• simulate -- imitate in appearance or character

Look into the cURL library. I've never used it in Java, but I'm sure there must be bindings for it. Basically, what you'll do is send a cURL request to whatever page you want to 'scrape'. The request will return a string with the source code to the page. From there, you will use regex to parse whatever data you want from the source code. That's generally how you are going to do it.

In DOS you couldn't use environment variables on the command line, only in batch files, where they used the % sign as a delimiter. If you wanted a literal % sign in a batch file, e.g. in an echo statement, you needed to double it.

This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your % signs in a .cmd file.

I wanted to do the same thing as, but I wanted to do it in the one file.

So the logic would be:

• if a script with my name is running, kill it, then exit
• if a script with my name is not running, do stuff

I modified the answer by Bakuriu and came up with this:

from os import getpid
from sys import argv, exit
import psutil  ## pip install psutil

myname = argv[0]
mypid = getpid()
for process in psutil.process_iter():
    if process.pid != mypid:
        for path in process.cmdline():
            if myname in path:
                print "process found"
                process.terminate()
                exit()

## your program starts here...

Running the script will do whatever the script does. Running another instance of the script will kill any existing instance of the script.

I use this to display a little PyGTK calendar widget which runs when I click the clock. If I click and the calendar is not up, the calendar displays. If the calendar is running and I click the clock, the calendar disappears.

Use the cmd activity start-activity (or the alternative am start) command, which is a command-line interface to the ActivityManager. Use am to start activities as shown in this help:

$ adb shell am
usage: am [start|instrument]
       am start [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>]
                [-c <CATEGORY> [-c <CATEGORY>] ...]
                [-e <EXTRA_KEY> <EXTRA_VALUE> [-e <EXTRA_KEY> <EXTRA_VALUE> ...]
                [-n <COMPONENT>] [-D] [<URI>]
       ...

For example, to start the Contacts application, and supposing you know only the package name but not the Activity, you can use

$ pkg=com.google.android.contacts
$ comp=$(adb shell cmd package resolve-activity --brief -c android.intent.category.LAUNCHER $pkg | tail -1)
$ adb shell cmd activity start-activity $comp

or the alternative

$ adb shell am start -n $comp

See also http://www.kandroid.org/online-pdk/guide/instrumentation_testing.html (may be a copy of obsolete url : http://source.android.com/porting/instrumentation_testing.html ) for other details.

To terminate the application you can use

$ adb shell am kill com.google.android.contacts

or the more drastic

$ adb shell am force-stop com.google.android.contacts

Creating and using the key is the way to go. The usage is free until your application reaches 25.000 calls per day on 90 consecutive days.

BTW.: In the google Developer documentation it says you shall add the api key as option {key:yourKey} when calling the API to create new instances. This however doesn't shush the console warning. You have to add the key as a parameter when including the api.

<script src="https://maps.googleapis.com/maps/api/js?key=yourKEYhere"></script>

Don't agree with post above. I have a Hero with only English available and I want Spanish.

I installed MoreLocale 2, and it has lots of different languages (Dutch among them). I choose Spanish, Sense UI restarted and EVERYTHING in my phone changed to Spanish: menus, settings, etc. The keyboard predictive text defaulted to Spanish and started suggesting words in Spanish. This means, somewhere within the OS there is a Spanish dictionary hidden and MoreLocale made it available.

The problem is that English is still the only option available in keyboard input language so I can switch to English but can't switch back to Spanish unless I restart Sense UI, which takes a couple of minutes so not a very practical solution.

Still looking for an easier way to do it so please help.

Yes. Use GetValues() method in System.Enum class.

myArray.sample

will return 1 random value.

myArray.shuffle.first

will also return 1 random value.

As already pointed out on this answer, KeyValuePair<TKey, TValue> implements a Deconstruct method starting on .NET Core 2.0, .NET Standard 2.1 and .NET Framework 5.0 (preview).

With this, it's possible to iterate through a dictionary in a KeyValuePair agnostic way:

var dictionary = new Dictionary<int, string>();

// ...

foreach (var (key, value) in dictionary)
{
    // ...
}

What you have done is created a new anonymous function that takes a single parameter which then gets assigned to the local variable myMessage inside the function. Since no arguments are actually passed, and arguments which aren't passed a value become null, your function just does alert(null).

This worked for me:

git branch

Copy the current branch name to clipboard

git pull origin <paste-branch-name>
git push

<style>
#outer { text-align: center; }
#inner { width:500px; text-align: left; margin: 0 auto; }
.t { float: left; width:240px; border: 1px solid black;}
#clearit { clear: both; }
</style>

Set alignment: Alignment.centerRight in Container:

Container(
    alignment: Alignment.centerRight,
    child:Text(
       "Hello",
    ),
)

Try this on Debian/Ubuntu:

sudo apt-get install python-mechanize

I got the similiar issue, and resolved it by the following. The issue looks not related to the Route definition but definition of the parameters, just need to give it a default value.

----Code with issue: Message: "No HTTP resource was found that matches the request URI

    [HttpGet]
    [Route("students/list")]
    public StudentListResponse GetStudents(int? ClassId, int? GradeId)
    {
       ...
    }

----Code without issue.

    [HttpGet]
    [Route("students/list")]
    public StudentListResponse GetStudents(int? ClassId=null, int? GradeId=null)
    {
       ...
    }

UPDATE: Check out AngularUI's new project to address this problem

For subsections it's as easy as leveraging strings in ng-include:

<ul id="subNav">
  <li><a ng-click="subPage='section1/subpage1.htm'">Sub Page 1</a></li>
  <li><a ng-click="subPage='section1/subpage2.htm'">Sub Page 2</a></li>
  <li><a ng-click="subPage='section1/subpage3.htm'">Sub Page 3</a></li>
</ul>
<ng-include src="subPage"></ng-include>

Or you can create an object in case you have links to sub pages all over the place:

$scope.pages = { page1: 'section1/subpage1.htm', ... };

<ul id="subNav">
  <li><a ng-click="subPage='page1'">Sub Page 1</a></li>
  <li><a ng-click="subPage='page2'">Sub Page 2</a></li>
  <li><a ng-click="subPage='page3'">Sub Page 3</a></li>
</ul>
<ng-include src="pages[subPage]"></ng-include>

Or you can even use $routeParams

$routeProvider.when('/home', ...);
$routeProvider.when('/home/:tab', ...);
$scope.params = $routeParams;

<ul id="subNav">
  <li><a href="#/home/tab1">Sub Page 1</a></li>
  <li><a href="#/home/tab2">Sub Page 2</a></li>
  <li><a href="#/home/tab3">Sub Page 3</a></li>
</ul>
<ng-include src=" '/home/' + tab + '.html' "></ng-include>

You can also put an ng-controller at the top-most level of each partial

You can use a css3 psuedo element (:before and/or :after) as shown in this article

https://www.exratione.com/2011/09/how-to-overflow-a-background-image-using-css3/

Good Luck...

I've used "TrueTime - part of Compuware's DevPartner suite for years. There's a [free version](you could try Compuware DevPartner Performance Analysis Community Edition.) available.

Basic debugging using Spring's DebugFilter can be configured like this:

@EnableWebSecurity
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.debug(true);
    }
}

You can press vi} to select the block surrounded with {} brackets where your cursor is currently located.

It doesn't really matter where you are inside that block (just make sure you are in the outermost one). Also you can change { to anything that has a pair like ) or ].

I have have this problem a number of times and there seems to be 2 ways of fixing it (shown below). You can use either of these properties to fix the rendering, or both at the same time.

Backface visibility hidden fixes the problem as it simplifies the animation to just the front of the object, whereas the default state is the front and the back.

backface-visibility: hidden;

TranslateZ also works as it is a hack to add hardware acceleration to the animation.

transform: translateZ(0);

Both of these properties fix the problem that you are having but some people also like to add

-webkit-font-smoothing: subpixel-antialiased;

to their animated to object. I find that it can change the rendering of a web font but feel free to experiment with that method too.

This problem happened for me when my Glass project was not using the SDK installed in Android Studio's default location. I was using another location I had previously from ADT, since I was trying to avoid re-downloading everything. Once I pointed the project back to the SDK location in Android Studio's install location the problem went away.

You should be able to do something like this:

byte[] bitmap = GetYourImage();

using(Image image = Image.FromStream(new MemoryStream(bitmap)))
{
    image.Save("output.jpg", ImageFormat.Jpeg);  // Or Png
}

Look here for more info.

Hopefully this helps.

The POSIX specification for find says:

-mtimen The primary shall evaluate as true if the file modification time subtracted from the initialization time, divided by 86400 (with any remainder discarded), is n.

Interestingly, the description of find does not further specify 'initialization time'. It is probably, though, the time when find is initialized (run).

In the descriptions, wherever n is used as a primary argument, it shall be interpreted as a decimal integer optionally preceded by a plus ( '+' ) or minus-sign ( '-' ) sign, as follows:

+n More than n.
  n Exactly n.
-n Less than n.

At the given time (2014-09-01 00:53:44 -4:00, where I'm deducing that AST is Atlantic Standard Time, and therefore the time zone offset from UTC is -4:00 in ISO 8601 but +4:00 in ISO 9945 (POSIX), but it doesn't matter all that much):

1409547224 = 2014-09-01 00:53:44 -04:00
1409457540 = 2014-08-30 23:59:00 -04:00

so:

1409547224 - 1409457540 = 89684
89684 / 86400 = 1

Even if the 'seconds since the epoch' values are wrong, the relative values are correct (for some time zone somewhere in the world, they are correct).

The n value calculated for the 2014-08-30 log file therefore is exactly 1 (the calculation is done with integer arithmetic), and the +1 rejects it because it is strictly a > 1 comparison (and not >= 1).

is is identity testing, == is equality testing. what happens in your code would be emulated in the interpreter like this:

>>> a = 'pub'
>>> b = ''.join(['p', 'u', 'b'])
>>> a == b
True
>>> a is b
False

so, no wonder they're not the same, right?

In other words: a is b is the equivalent of id(a) == id(b)

Linear scrolling animation to bottom. Pure JS, no JQuery. Maybe my solution will be helpful for someone.

let action_count = 8;
let speed_ms = 15;
let objDiv = document.getElementsByClassName('js_y5_area3').item(0);

let scroll_height = objDiv.scrollHeight;
let window_height = objDiv.offsetHeight;

let scroll_top = objDiv.scrollTop;
let need_scroll_top = scroll_height - window_height;

if (scroll_top < need_scroll_top)
{
    let step = Math.ceil((need_scroll_top - scroll_top) / action_count);

    let scrollInterval = setInterval(function()
    {
        scroll_top += step;
        objDiv.scrollTop = scroll_top;

        if (scroll_top >= need_scroll_top)
        {
            clearInterval(scrollInterval);
        }

    }, speed_ms);
}

You can change variables action_count, speed_ms to configure scrolling animation on your taste.

You can think of (tight or loose) coupling as being literally the amount of effort it would take you to separate a particular class from its reliance on another class. For example, if every method in your class had a little finally block at the bottom where you made a call to Log4Net to log something, then you would say your class was tightly coupled to Log4Net. If your class instead contained a private method named LogSomething which was the only place that called the Log4Net component (and the other methods all called LogSomething instead), then you would say your class was loosely coupled to Log4Net (because it wouldn't take much effort to pull Log4Net out and replace it with something else).

Another reason why you should avoid converting the column to varchar(max) is because you cannot create an index on a varchar(max) column.

You are probably seeking:

ActiveRecord::Base.connection.tables

and

ActiveRecord::Base.connection.columns('projects').map(&:name)

You should probably wrap them in shorter syntax inside your .irbrc.

Does this work?

Workbooks.Open Filename:=filepath, ReadOnly:=True

Or, as pointed out in a comment, to keep a reference to the opened workbook:

Dim book As Workbook
Set book = Workbooks.Open(Filename:=filepath, ReadOnly:=True)

The following also can be tried:

DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells

or use the other setting options in the DataGridViewAutoSizeColumnsMode Enum

There is no agreed upon naming convention for HTML and CSS. But you could structure your nomenclature around object design. More specifically what I call Ownership and Relationship.

Ownership

Keywords that describe the object, could be separated by hyphens.

car-new-turned-right

Keywords that describe the object can also fall into four categories (which should be ordered from left to right): Object, Object-Descriptor, Action, and Action-Descriptor.

car - a noun, and an object
new - an adjective, and an object-descriptor that describes the object in more detail
turned - a verb, and an action that belongs to the object
right - an adjective, and an action-descriptor that describes the action in more detail

Note: verbs (actions) should be in past-tense (turned, did, ran, etc).

Relationship

Objects can also have relationships like parent and child. The Action and Action-Descriptor belongs to the parent object, they don't belong to the child object. For relationships between objects you could use an underscore.

car-new-turned-right_wheel-left-turned-left

• car-new-turned-right (follows the ownership rule)
• wheel-left-turned-left (follows the ownership rule)
• car-new-turned-right_wheel-left-turned-left (follows the relationship rule)

Final notes:

• Because CSS is case-insensitive, it's better to write all names in lower-case (or upper-case); avoid camel-case or pascal-case as they can lead to ambiguous names.
• Know when to use a class and when to use an id. It's not just about an id being used once on the web page. Most of the time, you want to use a class and not an id. Web components like (buttons, forms, panels, ...etc) should always use a class. Id's can easily lead to naming conflicts, and should be used sparingly for namespacing your markup. The above concepts of ownership and relationship apply to naming both classes and ids, and will help you avoid naming conflicts.
• If you don't like my CSS naming convention, there are several others as well: Structural naming convention, Presentational naming convention, Semantic naming convention, BEM naming convention, OCSS naming convention, etc.

If you can live without tools.jar and it's only included as a chained dependency, you can exclude it from the offending project:

If you want to display single value access from database into textbox, please refer to the code below:

SqlConnection con=new SqlConnection("connection string");
SqlCommand cmd=new SqlConnection(SqlQuery,Con);
Con.Open();
TextBox1.Text=cmd.ExecuteScalar();
Con.Close();

or

SqlConnection con=new SqlConnection("connection string");
SqlCommand cmd=new SqlConnection(SqlQuery,Con);
Con.Open();
SqlDataReader dr=new SqlDataReadr();
dr=cmd.Executereader();
if(dr.read())
{
    TextBox1.Text=dr.GetValue(0).Tostring();
}
Con.Close();

Here you go:

function neat_trim($str, $n, $delim='…') {
   $len = strlen($str);
   if ($len > $n) {
       preg_match('/(.{' . $n . '}.*?)\b/', $str, $matches);
       return rtrim($matches[1]) . $delim;
   }
   else {
       return $str;
   }
}

Here is another option

$array = [1=>'one', 2=>'two', 3=>'there'];
$array = array_flip($array);
echo $array['one']; 

Use this code to pass arraylist<customobj> to anthother Activity

firstly serialize our contact bean

public class ContactBean implements Serializable {
      //do intialization here
}

Now pass your arraylist

 Intent intent = new Intent(this,name of activity.class);
 contactBean=(ConactBean)_arraylist.get(position);
 intent.putExtra("contactBeanObj",conactBean);
 _activity.startActivity(intent);

Technical Answer

Abstract classes cannot be instantiated - this is by definition and design.

From the JLS, Chapter 8. Classes:

A named class may be declared abstract (§8.1.1.1) and must be declared abstract if it is incompletely implemented; such a class cannot be instantiated, but can be extended by subclasses.

From JSE 6 java doc for Classes.newInstance():

InstantiationException - if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no nullary constructor; or if the instantiation fails for some other reason.

You can, of course, instantiate a concrete subclass of an abstract class (including an anonymous subclass) and also carry out a typecast of an object reference to an abstract type.

A Different Angle On This - Teamplay & Social Intelligence:

This sort of technical misunderstanding happens frequently in the real world when we deal with complex technologies and legalistic specifications.

"People Skills" can be more important here than "Technical Skills". If competitively and aggressively trying to prove your side of the argument, then you could be theoretically right, but you could also do more damage in having a fight / damaging "face" / creating an enemy than it is worth. Be reconciliatory and understanding in resolving your differences. Who knows - maybe you're "both right" but working off slightly different meanings for terms??

Who knows - though not likely, it is possible the interviewer deliberately introduced a small conflict/misunderstanding to put you into a challenging situation and see how you behave emotionally and socially. Be gracious and constructive with colleagues, follow advice from seniors, and follow through after the interview to resolve any challenge/misunderstanding - via email or phone call. Shows you're motivated and detail-oriented.

You should use some form of the String#equals(Object) method. However, there is some subtlety in how you should do it:

If you have a string literal then you should use it like this:

"Hello".equals(someString);

This is because the string literal "Hello" can never be null, so you will never run into a NullPointerException.

If you have a string and another object then you should use:

myString.equals(myObject);

You can make sure you are actually getting string equality by doing this. For all you know, myObject could be of a class that always returns true in its equals method!

Start with the object less likely to be null because this:

String foo = null;
String bar = "hello";
foo.equals(bar);

will throw a NullPointerException, but this:

String foo = null;
String bar = "hello";
bar.equals(foo);

will not. String#equals(Object) will correctly handle the case when its parameter is null, so you only need to worry about the object you are dereferencing--the first object.

nil? can be omitted in boolean contexts. Generally, you can use this to replicate the C# code:

return my_string.nil? || my_string.empty?

I wouldn't normally answer a question that already has 16 answers, but all the other answers are wrong, and the right answer is so simple. The question says, "Is there a simple way to delete all tracking branches whose remote equivalent no longer exists?"

If "simple" means deleting them all in one go, not fragile, not dangerous, and without reliance on tools that not all readers will have, then the right answer is: no.

Some answers are simple, but they don't do what was asked. Others do what was asked, but are not simple: all rely on parsing Git output through text-manipulation commands or scripting languages, which may not be present on every system. On top of that, most of the suggestions use porcelain commands, whose output is not designed to be parsed by script ("porcelain" refers to the commands intended for human operation; scripts should use the lower-level "plumbing" commands).

Further reading:

• why you shouldn't parse git branch output in a script.
• tracking branches and the differences between git remote prune, git prune, git fetch --prune

If you want to do this safely, for the use case in the question (garbage-collect tracking branches which have been deleted on the server but still exist as local branches) and with high-level Git commands only, you have to

• git fetch --prune (or git fetch -p, which is an alias, or git prune remote origin which does the same thing without fetching, and is probably not what you want most of the time).
• Note any remote branches that are reported as deleted. Or, to find them later on, git branch -v (any orphaned tracking branch will be marked "[gone]").
• git branch -d [branch_name] on each orphaned tracking branch

(which is what some of the other answers propose).

If you want to script a solution, then for-each-ref is your starting point, as in Mark Longair's answer here and this answer to another question, but I can't see a way to exploit it without writing a shell script loop, or using xargs or something.

Background explanation

To understand what's happening, you need to appreciate that, in the situation of tracking branches, you have not one branch, but three. (And recall that "branch" means simply a pointer to a commit.)

Given a tracking branch feature/X, the remote repository (server) will have this branch and call it feature/X. Your local repository has a branch remotes/origin/feature/X which means, "This is what the remote told me its feature/X branch was, last time we talked," and finally, the local repository has a branch feature/X which points to your latest commit, and is configured to "track" remotes/origin/feature/X, meaning that you can pull and push to keep them aligned.

At some point, someone has deleted the feature/X on the remote. From that moment, you are left with your local feature/X (which you probably don't want any more, since work on feature X is presumably finished), and your remotes/origin/feature/X which is certainly useless because its only purpose was to remember the state of the server's branch.

And Git will let you automatically clean up the redundant remotes/origin/feature/X -- that's what git fetch --prune does -- but for some reason, it doesn't let you automatically delete your own feature/X... even though your feature/X still contains the orphaned tracking information, so it has the information to identify former tracking branches that have been fully merged. (After all, it can give you the information that lets you do the operation by hand yourself.)

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

http://sassmeister.com/gist/9775949

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

@mixin tip($pos:right) {

}

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

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

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

If using make, issue with -j. From man make:

  -j [jobs], --jobs[=jobs]
       Specifies the number of jobs (commands) to run simultaneously.  
       If there is more than one -j option, the last one is effective.
       If the -j option is given without an argument, make will not limit the
       number of jobs that can run simultaneously.

And most notably, if you want to script or identify the number of cores you have available (depending on your environment, and if you run in many environments, this can change a lot) you may use ubiquitous Python function cpu_count():

https://docs.python.org/3/library/multiprocessing.html#multiprocessing.cpu_count

Like this:

make -j $(python3 -c 'import multiprocessing as mp; print(int(mp.cpu_count() * 1.5))')

If you're asking why 1.5 I'll quote user artless-noise in a comment above:

The 1.5 number is because of the noted I/O bound problem. It is a rule of thumb. About 1/3 of the jobs will be waiting for I/O, so the remaining jobs will be using the available cores. A number greater than the cores is better and you could even go as high as 2x.

sys.dm_exec_connections uses varchar(48) after SQL Server 2005 SP1. Sounds good enough for me especially if you want to use it compare to your value.

Realistically, you won't see IPv6 as mainstream for a while yet, so I'd prefer the 4 tinyint route. Saying that, I'm using varchar(48) because I have to use sys.dm_exec_connections...

Otherwise. Mark Redman's answer mentions a previous SO debate question.

return returns a value. It doesn't matter what name you gave to that value. Returning it just "passes it out" so that something else can use it. If you want to use it, you have to grab it from outside:

lst = defineAList()
useTheList(lst)

Returning list from inside defineAList doesn't mean "make it so the whole rest of the program can use that variable". It means "pass this variable out and give the rest of the program one chance to grab it and use it". You need to assign that value to something outside the function in order to make use of it. Also, because of this, there is no need to define your list ahead of time with list = []. Inside defineAList, you create a new list and return it; this list has no relationship to the one you defined with list = [] at the beginning.

Incidentally, I changed your variable name from list to lst. It's not a good idea to use list as a variable name because that is already the name of a built-in Python type. If you make your own variable called list, you won't be able to access the builtin one anymore.

Note that in Log4J 2.x, the public interface org.apache.logging.log4j.Logger doesn't include the setAppender() and removeAppender() methods.

But if you're not doing anything too fancy, you should be able to cast it to the implementation class org.apache.logging.log4j.core.Logger, which does expose those methods.

Here's an example with Mockito and AssertJ:

// Import the implementation class rather than the API interface
import org.apache.logging.log4j.core.Logger;

// Cast logger to implementation class to get access to setAppender/removeAppender
Logger log = (Logger) LogManager.getLogger(MyClassUnderTest.class);

// Set up the mock appender, stubbing some methods Log4J needs internally
Appender appender = mock(Appender.class);
when(appender.getName()).thenReturn("Mock Appender");
when(appender.isStarted()).thenReturn(true);

log.addAppender(appender);
try {
    new MyClassUnderTest().doSomethingThatShouldLogAnError();
} finally {
    log.removeAppender(appender);
}

// Verify that we got an error with the expected message
ArgumentCaptor<LogEvent> logEventCaptor = ArgumentCaptor.forClass(LogEvent.class);
verify(appender).append(logEventCaptor.capture());
LogEvent logEvent = logEventCaptor.getValue();
assertThat(logEvent.getLevel()).isEqualTo(Level.ERROR);
assertThat(logEvent.getMessage().getFormattedMessage()).contains(expectedErrorMessage);

@AlvinGeorge should just use:

extension UIImageView{        
    func blurImage()
    {
        let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.Dark)
        let blurEffectView = UIVisualEffectView(effect: blurEffect)
        blurEffectView.frame = self.bounds

        blurEffectView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight] // for supporting device rotation
        self.addSubview(blurEffectView)
    }
}

usage:

 blurredBackground.frame = self.view.bounds
 blurredBackground.blurImage()
 self.view.addSubview(self.blurredBackground)

Added for reference to future people who find this via google: You might want to look at the {% overextend %} tag provided by the mezzanine library for cases like this.

Documenting this answer for others, as there is a much simpler way to do this that is rarely referenced, and doesn't require touching the XAML at all.

To link a keyboard shortcut, in the Window constructor simply add a new KeyBinding to the InputBindings collection. As the command, pass in your arbitrary command class that implements ICommand. For the execute method, simply implement whatever logic you need. In my example below, my WindowCommand class takes a delegate that it will execute whenever invoked. When I construct the new WindowCommand to pass in with my binding, I simply indicate in my initializer, the method that I want the WindowCommand to execute.

You can use this pattern to come up with your own quick keyboard shortcuts.

public YourWindow() //inside any WPF Window constructor
{
   ...
   //add this one statement to bind a new keyboard command shortcut
   InputBindings.Add(new KeyBinding( //add a new key-binding, and pass in your command object instance which contains the Execute method which WPF will execute
      new WindowCommand(this)
      {
         ExecuteDelegate = TogglePause //REPLACE TogglePause with your method delegate
      }, new KeyGesture(Key.P, ModifierKeys.Control)));
   ...
}

Create a simple WindowCommand class which takes an execution delegate to fire off any method set on it.

public class WindowCommand : ICommand
{
    private MainWindow _window;

    //Set this delegate when you initialize a new object. This is the method the command will execute. You can also change this delegate type if you need to.
    public Action ExecuteDelegate { get; set; }

    //You don't have to add a parameter that takes a constructor. I've just added one in case I need access to the window directly.
    public WindowCommand(MainWindow window)
    {
        _window = window;
    }

    //always called before executing the command, mine just always returns true
    public bool CanExecute(object parameter)
    {
        return true; //mine always returns true, yours can use a new CanExecute delegate, or add custom logic to this method instead.
    }

    public event EventHandler CanExecuteChanged; //i'm not using this, but it's required by the interface

    //the important method that executes the actual command logic
    public void Execute(object parameter)
    {
        if (ExecuteDelegate != null)
        {
            ExecuteDelegate();
        }
        else
        {
            throw new InvalidOperationException();
        }
    }
}

Use the correct call: strptime is a classmethod of the datetime.datetime class, it's not a function in the datetime module.

self.date = datetime.datetime.strptime(self.d, "%Y-%m-%d")

As mentioned by Jon Clements in the comments, some people do from datetime import datetime, which would bind the datetime name to the datetime class, and make your initial code work.

To identify which case you're facing (in the future), look at your import statements

• import datetime: that's the module (that's what you have right now).
• from datetime import datetime: that's the class.

Well, I didn't like any of those answers, my solution of the same problem was to add this:<div>&nbsp;</div>. So in your scheme it would look like this (more or less), no style changes were necessary in my case:

-row-fluid-------------------------------------
+-span6----------+ +----span6----------+
|                | | +---div---+       |
| content        | | | & nbsp; |       |
| that           | | +---------+       |
| is tall        | | +-----div--------+|   
|                | | |short content   ||
|                | | +----------------+|
+----------------+ +-------------------+

One other possible solution we just found after having this issue across multiple databases/tables on the same server.

Is the max connections open to the sql server. We had an app that wasn't closing it's SQL connection and was leaving them open so we were running around 28K-31K connections (SQL Sever has a max out at 32K ish), and we noticed that once we killed a few thousand sleeping connections it took care of the error listed on this question.

The fix was to update the apps to make sure they closed their connections instead of leaving them open.

This is what I do, just add \n and use encodeURIComponent

Example

var emailBody = "1st line.\n 2nd line \n 3rd line";

emailBody = encodeURIComponent(emailBody);

href = "mailto:[email protected]?body=" + emailBody;

Check encodeURIComponent docs

#Creating dictionary
animals = {"Cat" : "Pat", "Dog" : "Pat", "Tiger" : "Wild"}

#Convert dictionary to list (array)
keys = list(animals)

#Printing 1st dictionary key by index
print(keys[0])

#Done :)

table {
    background: #fff;
    box-shadow: 0 0 0 10px #fff;
    margin: 10px;
    width: calc(100% - 20px); 
}

You can try this:

You must follow the following format

    $('element,id,class').on('click', function(){....});

*JQuery code*

    $('body').addClass('.anything').on('click', function(){
      //do some code here i.e
      alert("ok");
    });

After spending lot of time I have solved the problem

 string strDate = PreocessDate(data);
 string[] dateString = strDate.Split('/');
 DateTime enter_date = Convert.ToDateTime(dateString[1]+"/"+dateString[0]+"/"+dateString[2]);

Inner join - An inner join using either of the equivalent queries gives the intersection of the two tables, i.e. the two rows they have in common.
Left outer join - A left outer join will give all rows in A, plus any common rows in B.
Full outer join - A full outer join will give you the union of A and B, i.e. All the rows in A and all the rows in B. If something in A doesn't have a corresponding datum in B, then the B portion is null, and vice versa. check this

There are these tools in the GNU C Library, which includes GetOpt.

If you are using Qt and like the GetOpt interface, froglogic has published a nice interface here.

By convention, the directory src/main/resources contains the resources that will be used by the application. So Maven will include them in the final JAR.

Thus in your application, you will access them using the getResourceAsStream() method, as the resources are loaded in the classpath.

If you need to have them outside your application, do not store them in src/main/resources as they will be bundled by Maven. Of course, you can exclude them (using the link given by chkal) but it is better to create another directory (for example src/main/external-resources) in order to keep the conventions regarding the src/main/resources directory.

In the latter case, you will have to deliver the resources independently as your JAR file (this can be achieved by using the Assembly plugin). If you need to access them in your Eclipse environment, go to the Properties of your project, then in Java Build Path in Sources tab, add the folder (for example src/main/external-resources). Eclipse will then add this directory in the classpath.

You can also use this library which wraps HttpWebRequest and Response into simple methods that return objects based on the results. It uses some of the techniques described in these answers and has plenty of code inspired by answers from this and similar threads. It automatically catches any exceptions, seeks to abstract as much boiler plate code needed to make these web requests as possible, and automatically deserializes the response object.

An example of what your code would look like using this wrapper is as simple as

    var response = httpClient.Get<SomeResponseObject>(request);
    
    if(response.StatusCode == HttpStatusCode.OK)
    {
        //do something with the response
        console.Writeline(response.Body.Id); //where the body param matches the object you pass in as an anonymous type.  
    }else {
         //do something with the error
         console.Writelint(string.Format("{0}: {1}", response.StatusCode.ToString(), response.ErrorMessage);

    }

Full disclosure This library is a free open source wrapper library, and I am the author of said library. I make no money off of this but have found it immensely useful over the years and am sure anyone who is still using the HttpWebRequest / HttpWebResponse classes will too.

It is not a silver bullet but supports get, post, delete with both async and non-async for get and post as well as JSON or XML requests and responses. It is being actively maintained as of 6/21/2020

You should always catch exceptions as concrete as possible, so you should use

try
{
    //code
}
catch (Web2PDFException ex)
{
    //Handle the exception here
}

You chould of course use something like this if you insist:

try
{
}
catch (Exception err)
{
    if (err is Web2PDFException)
    {
        //Code
    }
}

Not PIL, but imageio.imread might still be interesting:

import imageio
im = scipy.misc.imread('um_000000.png', flatten=False, mode='RGB')
im = imageio.imread('Figure_1.png', pilmode='RGB')
print(im.shape)

gives

(480, 640, 3)

so it is (height, width, channels). So the pixel at position (x, y) is

color = tuple(im[y][x])
r, g, b = color

Outdated

scipy.misc.imread is deprecated in SciPy 1.0.0 (thanks for the reminder, fbahr!)

I Just installed Mountain Lion and had the same problem I use FLashBuilder (which is 32bit) and MountainLion is 64bit, which means by default MacPorts installs everything as 64bit. The version of subclipse I use is 1.8 As i had already installed Subversion and JavaHLBindings I just ran this command:

 sudo port upgrade --enforce-variants active +universal 

This made mac ports go through everything already installed and also install the 32bit version.

I then restarted FlashBuilder and it no longer showed any JavaHL errors.

You can use this code

     <script>
                // Replace the <textarea id="editor"> with a CKEditor
                // instance, using default configuration.

                CKEDITOR.config.filebrowserImageBrowseUrl = '/admin/laravel-filemanager?type=Files';
                CKEDITOR.config.filebrowserImageUploadUrl = '/admin/laravel-filemanager/upload?type=Images&_token=';
                CKEDITOR.config.filebrowserBrowseUrl = '/admin/laravel-filemanager?type=Files';
                CKEDITOR.config.filebrowserUploadUrl = '/admin/laravel-filemanager/upload?type=Files&_token=';

                CKEDITOR.replaceAll( 'editor');
   </script>

The easiest solution I found for this:

git commit -m "fixing merge conflicts"
git push

You can loop all of the array and add into ArrayList:

ArrayList<String> files = new ArrayList<String>(filesOrig.length);
for(String file: filesOrig) {
    files.add(file);
}

Or use Arrays.asList(T... a) to do as the comment posted.

You just need to put "group(1)" instead of "group()" in the following line and the return will be the one you expected:

System.out.println("I found the text: " + matcher.group(**1**).toString());

Apple sort of rearranged/repurposed the fields.

Going forward, if you look on the Info tab for your Application Target, you should use the "Bundle versions string, short" as your Version (e.g., 3.4.0) and "Bundle version" as your Build (e.g., 500 or 1A500). If you don't see them both, you can add them. Those will map to the proper Version and Build textboxes on the Summary tab; they are the same values.

When viewing the Info tab, if you right-click and select Show Raw Keys/Values, you'll see the actual names are CFBundleShortVersionString (Version) and CFBundleVersion (Build).

The Version is usually used how you appear to have been using it with Xcode 3. I'm not sure on what level you're asking about the Version/Build difference, so I'll answer it philosophically.

There are all sorts of schemes, but a popular one is:

{MajorVersion}.{MinorVersion}.{Revision}

• Major version - Major changes, redesigns, and functionality changes
• Minor version - Minor improvements, additions to functionality
• Revision - A patch number for bug-fixes

Then the Build is used separately to indicate the total number of builds for a release or for the entire product lifetime.

Many developers start the Build number at 0, and every time they build they increase the number by one, increasing forever. In my projects, I have a script that automatically increases the build number every time I build. See instructions for that below.

• Release 1.0.0 might be build 542. It took 542 builds to get to a 1.0.0 release.
• Release 1.0.1 might be build 578.
• Release 1.1.0 might be build 694.
• Release 2.0.0 might be build 949.

Other developers, including Apple, have a Build number comprised of a major version + minor version + number of builds for the release. These are the actual software version numbers, as opposed to the values used for marketing.

If you go to Xcode menu > About Xcode, you'll see the Version and Build numbers. If you hit the More Info... button you'll see a bunch of different versions. Since the More Info... button was removed in Xcode 5, this information is also available from the Software > Developer section of the System Information app, available by opening Apple menu > About This Mac > System Report....

For example, Xcode 4.2 (4C139). Marketing version 4.2 is Build major version 4, Build minor version C, and Build number 139. The next release (presumably 4.3) will likely be Build release 4D, and the Build number will start over at 0 and increment from there.

The iPhone Simulator Version/Build numbers are the same way, as are iPhones, Macs, etc.

• 3.2: (7W367a)
• 4.0: (8A400)
• 4.1: (8B117)
• 4.2: (8C134)
• 4.3: (8H7)

Update: By request, here are the steps to create a script that runs each time you build your app in Xcode to read the Build number, increment it, and write it back to the app's {App}-Info.plist file. There are optional, additional steps if you want to write your version/build numbers to your Settings.bundle/Root*.plist file(s).

This is extended from the how-to article here.

In Xcode 4.2 - 5.0:

1. Load your Xcode project.
2. In the left hand pane, click on your project at the very top of the hierarchy. This will load the project settings editor.
3. On the left-hand side of the center window pane, click on your app under the TARGETS heading. You will need to configure this setup for each project target.
4. Select the Build Phases tab.
5. • In Xcode 4, at the bottom right, click the Add Build Phase button and select Add Run Script.
   • In Xcode 5, select Editor menu > Add Build Phase > Add Run Script Build Phase.
6. Drag-and-drop the new Run Script phase to move it to just before the Copy Bundle Resources phase (when the app-info.plist file will be bundled with your app).
7. In the new Run Script phase, set Shell: /bin/bash.

8. Copy and paste the following into the script area for integer build numbers:

   buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
   buildNumber=$(($buildNumber + 1))
   /usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"
   

   As @Bdebeez pointed out, the Apple Generic Versioning Tool (agvtool) is also available. If you prefer to use it instead, then there are a couple things to change first:

   • Select the Build Settings tab.
   • Under the Versioning section, set the Current Project Version to the initial build number you want to use, e.g., 1.
   • Back on the Build Phases tab, drag-and-drop your Run Script phase after the Copy Bundle Resources phase to avoid a race condition when trying to both build and update the source file that includes your build number.

   Note that with the agvtool method you may still periodically get failed/canceled builds with no errors. For this reason, I don't recommend using agvtool with this script.

   Nevertheless, in your Run Script phase, you can use the following script:

   "${DEVELOPER_BIN_DIR}/agvtool" next-version -all
   

   The next-version argument increments the build number (bump is also an alias for the same thing), and -all updates Info.plist with the new build number.

9. And if you have a Settings bundle where you show the Version and Build, you can add the following to the end of the script to update the version and build. Note: Change the PreferenceSpecifiers values to match your settings. PreferenceSpecifiers:2 means look at the item at index 2 under the PreferenceSpecifiers array in your plist file, so for a 0-based index, that's the 3rd preference setting in the array.

   productVersion=$(/usr/libexec/PlistBuddy -c "Print CFBundleShortVersionString" "$INFOPLIST_FILE")
   /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:2:DefaultValue $buildNumber" Settings.bundle/Root.plist
   /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:1:DefaultValue $productVersion" Settings.bundle/Root.plist
   

   If you're using agvtool instead of reading the Info.plist directly, you can add the following to your script instead:

   buildNumber=$("${DEVELOPER_BIN_DIR}/agvtool" what-version -terse)
   productVersion=$("${DEVELOPER_BIN_DIR}/agvtool" what-marketing-version -terse1)
   /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:2:DefaultValue $buildNumber" Settings.bundle/Root.plist
   /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:1:DefaultValue $productVersion" Settings.bundle/Root.plist
   

10. And if you have a universal app for iPad & iPhone, then you can also set the settings for the iPhone file:

    /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:2:DefaultValue $buildNumber" Settings.bundle/Root~iphone.plist    
    /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:1:DefaultValue $productVersion" Settings.bundle/Root~iphone.plist
    

Your class Delivery has no access modifier, which means it defaults to internal. If you then try to expose a property of that type as public, it won't work. Your type (class) needs to have the same, or higher access as your property.

@PeYoTIL's answer using BeautifulSoup and eliminating style and script content didn't work for me. I tried it using decompose instead of extract but it still didn't work. So I created my own which also formats the text using the <p> tags and replaces <a> tags with the href link. Also copes with links inside text. Available at this gist with a test doc embedded.

from bs4 import BeautifulSoup, NavigableString

def html_to_text(html):
    "Creates a formatted text email message as a string from a rendered html template (page)"
    soup = BeautifulSoup(html, 'html.parser')
    # Ignore anything in head
    body, text = soup.body, []
    for element in body.descendants:
        # We use type and not isinstance since comments, cdata, etc are subclasses that we don't want
        if type(element) == NavigableString:
            # We use the assumption that other tags can't be inside a script or style
            if element.parent.name in ('script', 'style'):
                continue

            # remove any multiple and leading/trailing whitespace
            string = ' '.join(element.string.split())
            if string:
                if element.parent.name == 'a':
                    a_tag = element.parent
                    # replace link text with the link
                    string = a_tag['href']
                    # concatenate with any non-empty immediately previous string
                    if (    type(a_tag.previous_sibling) == NavigableString and
                            a_tag.previous_sibling.string.strip() ):
                        text[-1] = text[-1] + ' ' + string
                        continue
                elif element.previous_sibling and element.previous_sibling.name == 'a':
                    text[-1] = text[-1] + ' ' + string
                    continue
                elif element.parent.name == 'p':
                    # Add extra paragraph formatting newline
                    string = '\n' + string
                text += [string]
    doc = '\n'.join(text)
    return doc

You can achieve this by utilizing the jsPDF library and the toDataURL function.

I made a little demonstration:

You can set left margins for li tags in percents and set the same negative left margin on parent:

They are called the Positional Parameters.

3.4.1 Positional Parameters

A positional parameter is a parameter denoted by one or more digits, other than the single digit 0. Positional parameters are assigned from the shell’s arguments when it is invoked, and may be reassigned using the set builtin command. Positional parameter N may be referenced as ${N}, or as $N when N consists of a single digit. Positional parameters may not be assigned to with assignment statements. The set and shift builtins are used to set and unset them (see Shell Builtin Commands). The positional parameters are temporarily replaced when a shell function is executed (see Shell Functions).

When a positional parameter consisting of more than a single digit is expanded, it must be enclosed in braces.

Just surfed in from the web and felt I could contribute. I noticed that with the above code posted by @calethebrewer can result in multiple calls over the selector and unexpected behaviour for example: -

$(document).on('mouseover', '.selector', function() {
   //do something
});
$(document).on('mouseout', '.selector', function() {
   //do something
});

This fiddle http://jsfiddle.net/TWskH/12/ illustraits my point. When animating elements such as in plugins I have found that these multiple triggers result in unintended behavior which may result in the animation or code being called more than is necessary.

My suggestion is to simply replace with mouseenter/mouseleave: -

$(document).on('mouseenter', '.selector', function() {
   //do something
});
$(document).on('mouseleave', '.selector', function() {
   //do something
});

Although this prevented multiple instances of my animation from being called, I eventually went with mouseover/mouseleave as I needed to determine when children of the parent were being hovered over.

You should use datetime.datetime.strptime:

import datetime

dt = datetime.datetime.strptime(string_date, fmt)

fmt will need to be the appropriate format for your string. You'll find the reference on how to build your format here.

Use Any() instead of Contains():

buildingStatus.Any(item => item.GetCharValue() == v.Status)

You can get a View's coordinates using getLocationOnScreen() or getLocationInWindow()

Afterwards, x and y should be the top-left corner of the view. If your root layout is smaller than the screen (like in a Dialog), using getLocationInWindow will be relative to its container, not the entire screen.

Java Solution

int[] point = new int[2];
view.getLocationOnScreen(point); // or getLocationInWindow(point)
int x = point[0];
int y = point[1];

NOTE: If value is always 0, you are likely changing the view immediately before requesting location.

To ensure view has had a chance to update, run your location request after the View's new layout has been calculated by using view.post:

view.post(() -> {
    // Values should no longer be 0
    int[] point = new int[2];
    view.getLocationOnScreen(point); // or getLocationInWindow(point)
    int x = point[0];
    int y = point[1];
});

~~

Kotlin Solution

val point = IntArray(2)
view.getLocationOnScreen(point) // or getLocationInWindow(point)
val (x, y) = point

NOTE: If value is always 0, you are likely changing the view immediately before requesting location.

To ensure view has had a chance to update, run your location request after the View's new layout has been calculated by using view.post:

view.post {
    // Values should no longer be 0
    val point = IntArray(2)
    view.getLocationOnScreen(point) // or getLocationInWindow(point)
    val (x, y) = point
}

I recommend creating an extension function for handling this:

// To use, call:
val (x, y) = view.screenLocation

val View.screenLocation get(): IntArray {
    val point = IntArray(2)
    getLocationOnScreen(point)
    return point
}

And if you require reliability, also add:

view.screenLocationSafe { x, y -> Log.d("", "Use $x and $y here") }

fun View.screenLocationSafe(callback: (Int, Int) -> Unit) {
    post {
        val (x, y) = screenLocation
        callback(x, y)
    }
}

You need to fetch all "numbers" manually

like this:

var currentdate = new Date(); _x000D_
    var datetime = "Now: " + currentdate.getDate() + "/"_x000D_
                + (currentdate.getMonth()+1)  + "/" _x000D_
                + currentdate.getFullYear() + " @ "  _x000D_
                + currentdate.getHours() + ":"  _x000D_
                + currentdate.getMinutes() + ":" _x000D_
                + currentdate.getSeconds();_x000D_
_x000D_
document.write(datetime);

For this you probably want myString.PadRight(totalLength, charToInsert).

See String.PadRight Method (Int32) for more info.

The following code works for me on owl carousel .

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

Amit's answer tells you how to get your AWS_ACCESS_KEY_ID, but the Your Security Credentials page won't reveal your AWS_SECRET_ACCESS_KEY. As this blog points out:

Secret access keys are, as the name implies, secrets, like your password. Just as AWS doesn’t reveal your password back to you if you forgot it (you’d have to set a new password), the new security credentials page does not allowing retrieval of a secret access key after its initial creation. You should securely store your secret access keys as a security best practice, but you can always generate new access keys at any time.

So if you don't remember your AWS_SECRET_ACCESS_KEY, the blog goes on to tell how to create a new one:

1. Create a new access key:

2. "Download the .csv key file, which contains the access key ID and secret access key.":

As for your other questions:

• I'm not sure about MERCHANT_ID and MARKETPLACE_ID.
• I believe your sandbox question was addressed by Amit's point that you can play with AWS for a year without paying.

I happen to have implemented it, and it works in most cases. Since it is long, I put it in a file here.

The idea is to find the location of the class source file which is available in most cases (a known exception are JVM class files -- as far as I've tested). If the code is in a directory, scan through all files and only spot class files. If the code is in a JAR file, scan all entries.

This method can only be used when:

1. You have a class that is in the same package you want to discover, This class is called a SeedClass. For example, if you want to list all classes in 'java.io', the seed class may be java.io.File.

2. Your classes are in a directory or in a JAR file it has source file information (not source code file, but just source file). As far as I've tried, it work almost 100% except the JVM class (those classes come with the JVM).

3. Your program must have permission to access ProtectionDomain of those classes. If your program is loaded locally, there should be no problem.

I've tested the program only for my regular usage, so it may still have problem.

I hope this helps.
