How about Freebase? I think they have an API available, too.

http://www.freebase.com/

Since the desired page will be called from a different domain you need to return jsonp instead of a json.

$.get("http://theSource", {callback : "?" }, "jsonp",  function(data) {
    $('#summary').text(data.result);
});

You can use the following code to hide a table column..

JQuery("tableName").hideCol("colName");

And you can use the following code to show it again.

JQuery("tableName").showCol("colName");

For your question, you can call the hideCol() code on the document.ready(), and you can bind the showCol() code on the dialog's edit/click event.

That's because operator overloading is something they specifically left out of the language deliberately. They "cheated" a bit with string concatenation, but beyond that, such functionality doesn't exist.

(disclaimer: I haven't worked with the last 2 major releases of java, so if it's in now, I'll be very surprised)

Use code as follows:

mylist <- lapply(pressure, function(i)read.xlsx(i,colNames = FALSE))#
mydata <- do.call('rbind',mylist)#

startdate.setDate(startdate.getDate() - daysToSubtract);


startdate.setDate(startdate.getDate() + daysToAdd);

Your Customer class has to be discovered by CDI as a bean. For that you have two options:

1. Put a bean defining annotation on it. As @Model is a stereotype it's why it does the trick. A qualifier like @Named is not a bean defining annotation, reason why it doesn't work

2. Change the bean discovery mode in your bean archive from the default "annotated" to "all" by adding a beans.xml file in your jar.

Keep in mind that @Named has only one usage : expose your bean to the UI. Other usages are for bad practice or compatibility with legacy framework.

.setGame is discontinued. Use:

client.user.setActivity("Game"); 

To set a playing game status.

As an addition, if you were using an earlier version of discord.js, try this:

client.user.setGame("Game");

In newer versions of discord.js, this is deprecated.

Use the method "toArray()"

ArrayList<String>  mStringList= new ArrayList<String>();
mStringList.add("ann");
mStringList.add("john");
Object[] mStringArray = mStringList.toArray();

for(int i = 0; i < mStringArray.length ; i++){
    Log.d("string is",(String)mStringArray[i]);
}

or you can do it like this: (mentioned in other answers)

ArrayList<String>  mStringList= new ArrayList<String>();
mStringList.add("ann");
mStringList.add("john");
String[] mStringArray = new String[mStringList.size()];
mStringArray = mStringList.toArray(mStringArray);

for(int i = 0; i < mStringArray.length ; i++){
    Log.d("string is",(String)mStringArray[i]);
}

SRCS=$(wildcard *.c)

OBJS=$(SRCS:.c=.o)

all: $(OBJS)

just trigger a click, it's work for me:

$("#tabX").trigger("click");

i found the easiest way was to just remove/delete the .m2 folder and recreate it, putting back your settings.xml configuration details(if applicable).

Symfony 2.7 has a new absolute_url which can be used to generate the absolute url. http://symfony.com/blog/new-in-symfony-2-7-the-new-asset-component#template-function-changes

It will work on those both cases or a path string:

<a href="{{ absolute_url(path('route_name', {'param' : value})) }}">A link</a>

and for assets:

<img src="{{ absolute_url(asset('bundle/myname/img/image.gif')) }}" alt="Title"/>

Or for any string path

<img src="{{ absolute_url('my/absolute/path') }}" alt="Title"/>

on those tree cases you will end up with an absolute URL like

http://www.example.com/my/absolute/path

Here's a script that uses GNU sort's random option:

ls |sort -R |tail -$N |while read file; do
    # Something involving $file, or you can leave
    # off the while to just get the filenames
done

The nicest solution I have found is to do the following in the first view controller.

Objective-C

- (void)viewWillAppear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:YES animated:animated];
    [super viewWillAppear:animated];
}

- (void)viewWillDisappear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:NO animated:animated];
    [super viewWillDisappear:animated];
}

Swift

override func viewWillAppear(_ animated: Bool) {
    self.navigationController?.setNavigationBarHidden(true, animated: animated)
    super.viewWillAppear(animated)
}

override func viewWillDisappear(_ animated: Bool) {
    self.navigationController?.setNavigationBarHidden(false, animated: animated)
    super.viewWillDisappear(animated)
} 

This will cause the navigation bar to animate in from the left (together with the next view) when you push the next UIViewController on the stack, and animate away to the left (together with the old view), when you press the back button on the UINavigationBar.

Please note also that these are not delegate methods, you are overriding UIViewController's implementation of these methods, and according to the documentation you must call the super's implementation somewhere in your implementation.

Once I found an xsd link on the top of the wsdl. Like this wsdl example from the web, you can see a link xsd1. The server has to be running to see it.

I recommend you just use rubyinstaller

It is recommended by the official Ruby page - see https://www.ruby-lang.org/en/downloads/

Ways of Installing Ruby

We have several tools on each major platform to install Ruby:

• On Linux/UNIX, you can use the package management system of your distribution or third-party tools (rbenv and RVM).
• On OS X machines, you can use third-party tools (rbenv and RVM).
• On Windows machines, you can use RubyInstaller.

I recommend my solution. My situation: g++(cygwin) on win10

My solution: Write a .bat batch file and execute compiler in that batch. compileCpp.bat

@echo off  
set PATH=%PATH%;C:\cygwin64\bin\
rm %~n1.exe
c++.exe -g %~dpnx1 -o %~dpn1.exe
%~n1.exe  

Console:

NPP_EXEC: "runCpp"
NPP_SAVE: E:\hw.cpp
CD: E:\
Current directory: E:\
cmd /c C:\cygwin64\bin\compileCpp.bat "hw.cpp"
Process started >>>
Hello World<<< Process finished. (Exit code 0)

Here is a realtime blurring overlay using RenderScript, which seems to be fast enough.

https://github.com/mmin18/RealtimeBlurView

You can use id(name) to check if two names represent the same object:

>>> a = b = c = [0, 3, 5]
>>> print(id(a), id(b), id(c))
46268488 46268488 46268488

Lists are mutable; it means you can change the value in place without creating a new object. However, it depends on how you change the value:

>>> a[0] = 1
>>> print(id(a), id(b), id(c))
46268488 46268488 46268488
>>> print(a, b, c)
[1, 3, 5] [1, 3, 5] [1, 3, 5]

If you assign a new list to a, then its id will change, so it won't affect b and c's values:

>>> a = [1, 8, 5]
>>> print(id(a), id(b), id(c))
139423880 46268488 46268488
>>> print(a, b, c)
[1, 8, 5] [1, 3, 5] [1, 3, 5]

Integers are immutable, so you cannot change the value without creating a new object:

>>> x = y = z = 1
>>> print(id(x), id(y), id(z))
507081216 507081216 507081216
>>> x = 2
>>> print(id(x), id(y), id(z))
507081248 507081216 507081216
>>> print(x, y, z)
2 1 1

I'm trying to learn how to do this myself, and it seems you can install the library like this:

cmake_minimum_required(VERSION 2.4.0)

project(mycustomlib)

# Find source files
file(GLOB SOURCES src/*.cpp)

# Include header files
include_directories(include)

# Create shared library
add_library(${PROJECT_NAME} SHARED ${SOURCES})

# Install library
install(TARGETS ${PROJECT_NAME} DESTINATION lib/${PROJECT_NAME})

# Install library headers
file(GLOB HEADERS include/*.h)
install(FILES ${HEADERS} DESTINATION include/${PROJECT_NAME})

you can use all cells as a object like this :

Dim x as Range
Set x = Worksheets("Sheet name").Cells

X is now a range object that contains the entire worksheet

As @Quentin and @Pointy pointed out in their comments, it's not a good idea to use parseInt() because it is designed to convert a string to an integer. When you pass a decimal number to it, it first converts the number to a string, then casts it to an integer. I suggest you use Math.trunc(), Math.floor(), ~~num, ~~v , num | 0, num << 0, or num >> 0 depending on your needs. This performance test demonstrates the difference in parseInt() and Math.floor() performance. Also, this post explains the difference between the proposed methods.

this error is also caused by null pointer reference. if you are using a pointer who is not initialized then it causes this error.

to check either a pointer is initialized or not you can try something like

Class *pointer = new Class();
if(pointer!=nullptr){
    pointer->myFunction();
}

If you write down a fractional value like 1 / 7 as decimal value you get

1/7 = 0.142857142857142857142857142857142857142857...

with an infinite sequence of 142857. Since you can only write a finite number of digits you will inevitably introduce a rounding (or truncation) error.

Numbers like 1/10 or 1/100 expressed as binary numbers with a fractional part also have an infinite number of digits after the decimal point:

1/10 = binary 0.0001100110011001100110011001100110...

Doubles store values as binary and therefore might introduce an error solely by converting a decimal number to a binary number, without even doing any arithmetic.

Decimal numbers (like BigDecimal), on the other hand, store each decimal digit as is (binary coded, but each decimal on its own). This means that a decimal type is not more precise than a binary floating point or fixed point type in a general sense (i.e. it cannot store 1/7 without loss of precision), but it is more accurate for numbers that have a finite number of decimal digits as is often the case for money calculations.

Java's BigDecimal has the additional advantage that it can have an arbitrary (but finite) number of digits on both sides of the decimal point, limited only by the available memory.

netstat -nlp should tell you the PID of what's listening on which port.

As far as I can tell what you could do is "retire" your previous app and redirect all users to your new app. This procedure is not supported by Google (tsk... tsk...), but it could be implemented in four steps:

1. Change the current application to show a message to the users about the upgrade and redirect them to the new app listing. Probably a full screen message would do with some friendly text. This message could be triggered remotely ideally, but a cut-off date can be used too. (But then that will be a hard deadline for you, so be careful... ;))

2. Release the modified old app as an upgrade, maybe with some feature upgrades/bug fixes too, to "sweeten the deal" to the users. Still there is no guarantee that all users will upgrade, but probably the majority will do.

3. Prepare your new app with the updated package name and upload it to the store, then trigger the message in the old app (or just wait until it expires, if that was your choice).

4. Unpublish the old app in Play Store to avoid any new installs. Unpublishing an app doesn't mean the users who already installed it won't have access to it anymore, but at least the potential new users won't find it on the market.

Not ideal and can be annoying to the users, sometimes even impossible to implement due to the status/possibilities of the app. But since Google left us no choice this is the only way to migrate the users of the old apps to a "new" one (even if it is not really new). Not to mention that if you don't have access to the sources and code signing details for the old app then all you could do is hoping that he users will notice the new app...

If anybody figured out a better way by all means: please do tell.

There is simply no need of using third party libraries. A little tweak in the method demonstrated in Google I/O 2016 and Heisenberg on this topic, does the trick.

Since notifyDataSetChanged() redraws the complete RecyclerView, notifyDataItemChanged() is a better option (not the best) because we have the position and the ViewHolder at our disposal, and notifyDataItemChanged() only redraws the particular ViewHolder at a given position.

But the problem is that the premature disappearence of the ViewHolder upon clicking and it's emergence is not eliminated even if notifyDataItemChanged() is used.

The following code does not resort to notifyDataSetChanged() or notifyDataItemChanged() and is Tested on API 23 and works like a charm when used on a RecyclerView where each ViewHolder has a CardView as it's root element:

holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            final boolean visibility = holder.details.getVisibility()==View.VISIBLE;

            if (!visibility)
            {
                holder.itemView.setActivated(true);
                holder.details.setVisibility(View.VISIBLE);
                if (prev_expanded!=-1 && prev_expanded!=position)
                {
                    recycler.findViewHolderForLayoutPosition(prev_expanded).itemView.setActivated(false);
                    recycler.findViewHolderForLayoutPosition(prev_expanded).itemView.findViewById(R.id.cpl_details).setVisibility(View.GONE);
                }
                prev_expanded = position;
            }
            else
            {
                holder.itemView.setActivated(false);
                holder.details.setVisibility(View.GONE);
            }
            TransitionManager.beginDelayedTransition(recycler);              
        }
});

prev_position is an global integer initialized to -1. details is the complete view which is shown when expanded and cloaked when collapsed.

As said, the root element of ViewHolder is a CardView with foreground and stateListAnimator attributes defined exactly as said by Heisenberg on this topic.

UPDATE: The above demonstration will collapse previosuly expanded item if one of them in expanded. To modify this behaviour and keep the an expanded item as it is even when another item is expanded, you'll need the following code.

if (row.details.getVisibility()!=View.VISIBLE)
    {
        row.details.setVisibility(View.VISIBLE);
        row.root.setActivated(true);
        row.details.animate().alpha(1).setStartDelay(500);
    }
    else
    {
        row.root.setActivated(false);
        row.details.setVisibility(View.GONE);
        row.details.setAlpha(0);
    }
    TransitionManager.beginDelayedTransition(recycler);

UPDATE: When expanding the last items on the list, it may not be brought into full visibility because the expanded portion goes below the screen. To get the full item within screen use the following code.

LinearLayoutManager manager = (LinearLayoutManager) recycler.getLayoutManager();
    int distance;
    View first = recycler.getChildAt(0);
    int height = first.getHeight();
    int current = recycler.getChildAdapterPosition(first);
    int p = Math.abs(position - current);
    if (p > 5) distance = (p - (p - 5)) * height;
    else       distance = p * height;
    manager.scrollToPositionWithOffset(position, distance);

IMPORTANT: For the above demonstrations to work, one must keep in their code an instance of the RecyclerView & it's LayoutManager (the later for flexibility)

Normally, you do something like this:

def myFunction(a,b,c):
   if not isinstance(a, int):
      raise TypeError("Expected int, got %s" % (type(a),))
   if b <= 0 or b >= 10:
      raise ValueError("Value %d out of range" % (b,))
   if not c:
      raise ValueError("String was empty")

   # Rest of function

You may try this. It solved my issue.

import matplotlib.image as mpimg
img = mpimg.imread("src.png")
mpimg.imsave("out.png", img, cmap=cmap)

The filter function can also provide an interesting solution:

result = list(filter(lambda x: x.count(1) > 0, a))

which searches the tuples in the list a for any occurrences of 1. If the search is limited to the first element, the solution can be modified into:

result = list(filter(lambda x: x[0] == 1, a))

As others have already mentioned you are required to provide a default constructor public Employee(){} in your Employee class.

What happens is that the compiler automatically provides a no-argument, default constructor for any class without constructors. If your class has no explicit superclass, then it has an implicit superclass of Object, which does have a no-argument constructor. In this case you are declaring a constructor in your class Employee therefore you must provide also the no-argument constructor.

Having said that Employee class should look like this:

Your class Employee

import java.util.Date;

public class Employee
{
      private String name, number;
      private Date date;

      public Employee(){} // No-argument Constructor

      public Employee(String name, String number, Date date)
      {
            setName(name);
            setNumber(number);
            setDate(date);
      }

      public void setName(String n)
      {
            name = n;
      }
      public void setNumber(String n)
      {
            number = n;
            // you can check the format here for correctness
      }
      public void setDate(Date d)
      {
            date = d;
      }

      public String getName()
      {
            return name;
      }
      public String getNumber()
      {
            return number;
      }
      public Date getDate()
      {
            return date;
      }
}

Here is the Java Oracle tutorial - Providing Constructors for Your Classes chapter. Go through it and you will have a clearer idea of what is going on.

Most / all answers caused issues for us when daylight savings time came around. Here's our working solution for all dates, without using JodaTime. It utilizes calendar objects:

public static int daysBetween(Calendar day1, Calendar day2){
    Calendar dayOne = (Calendar) day1.clone(),
            dayTwo = (Calendar) day2.clone();

    if (dayOne.get(Calendar.YEAR) == dayTwo.get(Calendar.YEAR)) {
        return Math.abs(dayOne.get(Calendar.DAY_OF_YEAR) - dayTwo.get(Calendar.DAY_OF_YEAR));
    } else {
        if (dayTwo.get(Calendar.YEAR) > dayOne.get(Calendar.YEAR)) {
            //swap them
            Calendar temp = dayOne;
            dayOne = dayTwo;
            dayTwo = temp;
        }
        int extraDays = 0;

        int dayOneOriginalYearDays = dayOne.get(Calendar.DAY_OF_YEAR);

        while (dayOne.get(Calendar.YEAR) > dayTwo.get(Calendar.YEAR)) {
            dayOne.add(Calendar.YEAR, -1);
            // getActualMaximum() important for leap years
            extraDays += dayOne.getActualMaximum(Calendar.DAY_OF_YEAR);
        }

        return extraDays - dayTwo.get(Calendar.DAY_OF_YEAR) + dayOneOriginalYearDays ;
    }
}

If you are using reactiveFormModule and have formGroup defined like this:

public exampleForm = new FormGroup({
        name: new FormControl('Test name', [Validators.required, Validators.minLength(3)]),
        email: new FormControl('[email protected]', [Validators.required, Validators.maxLength(50)]),
        age: new FormControl(45, [Validators.min(18), Validators.max(65)])
});

than you are able to add a new validator (and keep old ones) to FormControl with this approach:

this.exampleForm.get('age').setValidators([
        Validators.pattern('^[0-9]*$'),
        this.exampleForm.get('age').validator
]);
this.exampleForm.get('email').setValidators([
        Validators.email,
        this.exampleForm.get('email').validator
]);

FormControl.validator returns a compose validator containing all previously defined validators.

What about just using a global variable within your library, like so?

single.dart:

library singleton;

var Singleton = new Impl();

class Impl {
  int i;
}

main.dart:

import 'single.dart';

void main() {
  var a = Singleton;
  var b = Singleton;
  a.i = 2;
  print(b.i);
}

Or is this frowned upon?

The singleton pattern is necessary in Java where the concept of globals doesn't exist, but it seems like you shouldn't need to go the long way around in Dart.

Here is an elegant method using quaternions that are blazingly fast; I can calculate 10 million rotations per second with appropriately vectorised numpy arrays. It relies on the quaternion extension to numpy found here.

Quaternion Theory: A quaternion is a number with one real and 3 imaginary dimensions usually written as q = w + xi + yj + zk where 'i', 'j', 'k' are imaginary dimensions. Just as a unit complex number 'c' can represent all 2d rotations by c=exp(i * theta), a unit quaternion 'q' can represent all 3d rotations by q=exp(p), where 'p' is a pure imaginary quaternion set by your axis and angle.

We start by converting your axis and angle to a quaternion whose imaginary dimensions are given by your axis of rotation, and whose magnitude is given by half the angle of rotation in radians. The 4 element vectors (w, x, y, z) are constructed as follows:

import numpy as np
import quaternion as quat

v = [3,5,0]
axis = [4,4,1]
theta = 1.2 #radian

vector = np.array([0.] + v)
rot_axis = np.array([0.] + axis)
axis_angle = (theta*0.5) * rot_axis/np.linalg.norm(rot_axis)

First, a numpy array of 4 elements is constructed with the real component w=0 for both the vector to be rotated vector and the rotation axis rot_axis. The axis angle representation is then constructed by normalizing then multiplying by half the desired angle theta. See here for why half the angle is required.

Now create the quaternions v and qlog using the library, and get the unit rotation quaternion q by taking the exponential.

vec = quat.quaternion(*v)
qlog = quat.quaternion(*axis_angle)
q = np.exp(qlog)

Finally, the rotation of the vector is calculated by the following operation.

v_prime = q * vec * np.conjugate(q)

print(v_prime) # quaternion(0.0, 2.7491163, 4.7718093, 1.9162971)

Now just discard the real element and you have your rotated vector!

v_prime_vec = v_prime.imag # [2.74911638 4.77180932 1.91629719] as a numpy array

Note that this method is particularly efficient if you have to rotate a vector through many sequential rotations, as the quaternion product can just be calculated as q = q1 * q2 * q3 * q4 * ... * qn and then the vector is only rotated by 'q' at the very end using v' = q * v * conj(q).

This method gives you a seamless transformation between axis angle <---> 3d rotation operator simply by exp and log functions (yes log(q) just returns the axis-angle representation!). For further clarification of how quaternion multiplication etc. work, see here

Just for reference, a for loop can be used after getting the first row to get the rest of the file:

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    row1 = next(reader)  # gets the first line
    for row in reader:
        print(row)       # prints rows 2 and onward

The Decimal structure is strictly geared to financial calculations requiring accuracy, which are relatively intolerant of rounding. Decimals are not adequate for scientific applications, however, for several reasons:

• A certain loss of precision is acceptable in many scientific calculations because of the practical limits of the physical problem or artifact being measured. Loss of precision is not acceptable in finance.
• Decimal is much (much) slower than float and double for most operations, primarily because floating point operations are done in binary, whereas Decimal stuff is done in base 10 (i.e. floats and doubles are handled by the FPU hardware, such as MMX/SSE, whereas decimals are calculated in software).
• Decimal has an unacceptably smaller value range than double, despite the fact that it supports more digits of precision. Therefore, Decimal can't be used to represent many scientific values.

Here is the answer of my question. I've asked that again with some remarks. How to add support libraries?

I wrote a JavaScript function that returns the four coordinates of a square bounding box, given a distance and a pair of coordinates:

'use strict';

I was facing the problem in passing string value to string parameters in Ajax. After so much googling, i have come up with a custom solution as below.

var bar = 'xyz';
var calibri = 'no$libri';

$.ajax({
   type: "POST",
   dataType: "json",
   contentType: "application/json; charset=utf-8",
   url: "http://nakolesah.ru/",
   data: '{ foo: \'' + bar + '\', zoo: \'' + calibri + '\'}',
   success: function(msg){
       alert('wow'+msg);
   },
});

Here, bar and calibri are two string variables and you can pass whatever string value to respective string parameters in web method.

The present solution produces the same flow as your OP. It does not use Labels, but this was not a requirement of the OP. You only asked for "a simple conditional loop that will go to the next iteration if a condition is true", and since this is cleaner to read, it is likely a better option than that using a Label.

What you want inside your for loop follows the pattern

If (your condition) Then
    'Do something
End If

In this case, your condition is Not(Return = 0 And Level = 0), so you would use

For i = 2 To 24
    Level = Cells(i, 4)
    Return = Cells(i, 5)

    If (Not(Return = 0 And Level = 0)) Then
        'Do something
    End If
Next i

PS: the condition is equivalent to (Return <> 0 Or Level <> 0)

Hi Just addition to VonC comments. I am using ecj compiler to compile my project. it was throwing expcetion that some of the classes are not found. But the project was bulding fine with javac compiler.

So just I added the classes into the classpath(which we have to pass as argument) and now its working fine... :)

The clue is to work with the dict's items (i.e. key-value pair tuples). Then by using the second element of the item as the max key (as opposed to the dict key) you can easily extract the highest value and its associated key.

 mydict = {'A':4,'B':10,'C':0,'D':87}
>>> max(mydict.items(), key=lambda k: k[1])
('D', 87)
>>> min(mydict.items(), key=lambda k: k[1])
('C', 0)

In addition to using Request.Form and Request.QueryString and depending on your specific scenario, it may also be useful to check the Page's IsPostBack property.

if (Page.IsPostBack)
{
  // HTTP Post
}
else
{
  // HTTP Get
}

Write below code into your MainActivity file after setContentView(R.layout.activity_main);

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

And below import statement into your java file.

Adapted from this answer to a very similar question:

FORFILES /S /D -10 /C "cmd /c IF @isdir == TRUE rd /S /Q @path"

You should run this command from within your d:\study folder. It will delete all subfolders which are older than 10 days.

The /S /Q after the rd makes it delete folders even if they are not empty, without prompting.

I suggest you put the above command into a .bat file, and save it as d:\study\cleanup.bat.

I don't know about less verbose but I was inspired to coerce the following onto one line by the one-liner request, don't know how Pythonic it is though ;)

var keys = (function(o){var ks=[]; for(var k in o) ks.push(k); return ks})(foo);

You should add AutoPostBack="true" to DropDownList1

                <asp:DropDownList ID="ddmanu" runat="server" AutoPostBack="true"
                    DataSourceID="Sql_fur_model_manu"    
                    DataTextField="manufacturer" DataValueField="manufacturer" 
                    onselectedindexchanged="ddmanu_SelectedIndexChanged">
                </asp:DropDownList>

I used @ControllerAdvice , please check is available in Spring 3.X; I am using it in Spring 4.0.

public class CommonController extends ControllerBase{

Iterative solution as an alternative:

def traverse_nested_dict(d):
    iters = [d.iteritems()]

    while iters:
        it = iters.pop()
        try:
            k, v = it.next()
        except StopIteration:
            continue

        iters.append(it)

        if isinstance(v, dict):
            iters.append(v.iteritems())
        else:
            yield k, v


d = {"a": 1, "b": 2, "c": {"d": 3, "e": {"f": 4}}}
for k, v in traverse_nested_dict(d):
    print k, v

Use mysqli_fetch_row(). Try this,

$query = "SELECT ssfullname, ssemail FROM userss WHERE user_id = ".$user_id;
$result = mysqli_query($conn, $query);
$row   = mysqli_fetch_row($result);

$ssfullname = $row['ssfullname'];
$ssemail    = $row['ssemail'];

one thing I want to add , before you try to install

apt-get install php5-sqlite

or

apt-get install php5-sqlite3 

search the given package is available or not :-

 # apt-cache search 'php5'

After that you get :-

php5-rrd - rrd module for PHP 5

php5-sasl - Cyrus SASL extension for PHP 5

php5-snmp - SNMP module for php5

**php5-sqlite - SQLite module for php5**

php5-svn - PHP Bindings for the Subversion Revision control system

php5-sybase - Sybase / MS SQL Server module for php5

Here you get an idea about whether your version support or not .. in my system I get php5-sqlite - SQLite module for php5 so I prefer to install

**apt-get install php5-sqlite**

$data = json_decode(...);
$firstId = $data[0]["id"];
$secondSeatNo = $data[1]["seat_no"];

Just like this :)

I've written an extension method for this purpose:

public static byte[] FromBase64Bytes(this byte[] base64Bytes)
{
    string base64String = Encoding.UTF8.GetString(base64Bytes, 0, base64Bytes.Length);
    return Convert.FromBase64String(base64String);
}

Call it like this:

byte[] base64Bytes = .......
byte[] regularBytes = base64Bytes.FromBase64Bytes();

I hope it helps someone.

_{This answer is meant to be a rather short and sweet one to answer (part of) the titled question. If you want an answer with more detail that explains why you have to put them there, please go here.}

The general rule for putting the typename keyword is mostly when you're using a template parameter and you want to access a nested typedef or using-alias, for example:

template<typename T>
struct test {
    using type = T; // no typename required
    using underlying_type = typename T::type // typename required
};

Note that this also applies for meta functions or things that take generic template parameters too. However, if the template parameter provided is an explicit type then you don't have to specify typename, for example:

template<typename T>
struct test {
    // typename required
    using type = typename std::conditional<true, const T&, T&&>::type;
    // no typename required
    using integer = std::conditional<true, int, float>::type;
};

The general rules for adding the template qualifier are mostly similar except they typically involve templated member functions (static or otherwise) of a struct/class that is itself templated, for example:

Given this struct and function:

template<typename T>
struct test {
    template<typename U>
    void get() const {
        std::cout << "get\n";
    }
};

template<typename T>
void func(const test<T>& t) {
    t.get<int>(); // error
}

Attempting to access t.get<int>() from inside the function will result in an error:

main.cpp:13:11: error: expected primary-expression before 'int'
     t.get<int>();
           ^
main.cpp:13:11: error: expected ';' before 'int'

Thus in this context you would need the template keyword beforehand and call it like so:

t.template get<int>()

That way the compiler will parse this properly rather than t.get < int.

Use element.classList .contains method:

element.classList.contains(class);

This works on all current browsers and there are polyfills to support older browsers too.

Alternatively, if you work with older browsers and don't want to use polyfills to fix them, using indexOf is correct, but you have to tweak it a little:

function hasClass(element, className) {
    return (' ' + element.className + ' ').indexOf(' ' + className+ ' ') > -1;
}

Otherwise you will also get true if the class you are looking for is part of another class name.

DEMO

jQuery uses a similar (if not the same) method.

Applied to the example:

As this does not work together with the switch statement, you could achieve the same effect with this code:

var test = document.getElementById("test"),
    classes = ['class1', 'class2', 'class3', 'class4'];

test.innerHTML = "";

for(var i = 0, j = classes.length; i < j; i++) {
    if(hasClass(test, classes[i])) {
        test.innerHTML = "I have " + classes[i];
        break;
    }
}

It's also less redundant ;)

There is various way to define a function. It is totally based upon your requirement. Below are the few styles :-

1. Object Constructor
2. Literal constructor
3. Function Based
4. Protoype Based
5. Function and Prototype Based
6. Singleton Based

Examples:

1. Object constructor

var person = new Object();

person.name = "Anand",
person.getName = function(){
  return this.name ; 
};

2. Literal constructor

var person = { 
  name : "Anand",
  getName : function (){
   return this.name
  } 
} 

3. function Constructor

function Person(name){
  this.name = name
  this.getName = function(){
    return this.name
  } 
} 

4. Prototype

function Person(){};

Person.prototype.name = "Anand";

5. Function/Prototype combination

function Person(name){
  this.name = name;
} 
Person.prototype.getName = function(){
  return this.name
} 

6. Singleton

var person = new function(){
  this.name = "Anand"
} 

You can try it on console, if you have any confusion.

According to SQL2000 help, sp_spaceused includes data and indexes.

This script should do:

CREATE TABLE #t (name SYSNAME, rows CHAR(11), reserved VARCHAR(18), 
data VARCHAR(18), index_size VARCHAR(18), unused VARCHAR(18))

EXEC sp_msforeachtable 'INSERT INTO #t EXEC sp_spaceused ''?'''
-- SELECT * FROM #t ORDER BY name
-- SELECT name, CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3)) FROM #t ORDER BY name
SELECT SUM(CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3))) FROM #t
DROP TABLE #t

Go to the package.json file, check the "@angular/core" version. It is an actual project version.

Got a similar error on IIS Express with Visual Studio 2017.

HTTP Error 413.0 - Request Entity Too Large

The page was not displayed because the request entity is too large.

Most likely causes:

• The Web server is refusing to service the request because the request entity is too large.

• The Web server cannot service the request because it is trying to negotiate a client certificate but the request entity is too large.

• The request URL or the physical mapping to the URL (i.e., the physical file system path to the URL's content) is too long.

Things you can try:

• Verify that the request is valid.

• If using client certificates, try:

  • Increasing system.webServer/serverRuntime@uploadReadAheadSize

  • Configure your SSL endpoint to negotiate client certificates as part of the initial SSL handshake. (netsh http add sslcert ... clientcertnegotiation=enable) .vs\config\applicationhost.config

Solve this by editing \.vs\config\applicationhost.config. Switch serverRuntime from Deny to Allow like this:

<section name="serverRuntime" overrideModeDefault="Allow" />

If this value is not edited, you will get an error like this when setting uploadReadAheadSize:

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

Then edit Web.config with the following values:

<system.webServer>
  <serverRuntime uploadReadAheadSize="10485760" />
...

Found the solution after some searching.

You need to add a <meta> tag in your <head> containing name="theme-color", with your HEX code as the content value. For example:

<meta name="theme-color" content="#999999" />

Update:

If the android device has native dark-mode enabled, then this meta tag is ignored.

Chrome for Android does not use the color on devices with native dark-mode enabled.

source: https://caniuse.com/#search=theme-color

What error is it giving you?

If you do exactly this:

data = json.loads('{"lat":444, "lon":555}')

Then:

data['lat']

SHOULD NOT give you any error at all.

if (DateTime.TryParse(datetoparser, out dateValue))
{
   string formatedDate = dateValue.ToString("yyyy-MM-dd");
}

I know this is old but this answer still applies to newer Core releases.

If by chance your DbContext implementation is in a different project than your startup project and you run ef migrations, you'll see this error because the command will not be able to invoke the application's startup code leaving your database provider without a configuration. To fix it, you have to let ef migrations know where they're at.

dotnet ef migrations add MyMigration [-p <relative path to DbContext project>, -s <relative path to startup project>]

Both -s and -p are optionals that default to the current folder.

Detecting peaks in a spectrum in a reliable way has been studied quite a bit, for example all the work on sinusoidal modelling for music/audio signals in the 80ies. Look for "Sinusoidal Modeling" in the literature.

If your signals are as clean as the example, a simple "give me something with an amplitude higher than N neighbours" should work reasonably well. If you have noisy signals, a simple but effective way is to look at your peaks in time, to track them: you then detect spectral lines instead of spectral peaks. IOW, you compute the FFT on a sliding window of your signal, to get a set of spectrum in time (also called spectrogram). You then look at the evolution of the spectral peak in time (i.e. in consecutive windows).

Assuming employee numbers are in the first column and their names are in the second:

=VLOOKUP(A1, Sheet2!A:B, 2,false)

public void setUp() throws Exception {

 System.setProperty("webdriver.chrome.driver","Absolute path of Chrome driver");

 driver =new ChromeDriver();
 baseUrl = "URL/";

    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }

Check your DataFrame with data.columns

It should print something like this

Index([u'regiment', u'company',  u'name',u'postTestScore'], dtype='object')

Check for hidden white spaces..Then you can rename with

data = data.rename(columns={'Number ': 'Number'})

This worked for me (though it's for reactjs & tachyons used as inline CSS)

<div className="pa2 cf vh-100-ns" style={{backgroundImage: `url(${a6})`}}> 
........
</div>

This takes in css as height: 100vh

This works for me!!!

When you specify window features, it will open in a new window

Just like :

window.open(url,"_blank","top=100,left=200,width=1000,height=500");

I tend to use the Information_Schema:

IF EXISTS ( SELECT  1
            FROM    Information_schema.Routines
            WHERE   Specific_schema = 'dbo'
                    AND specific_name = 'Foo'
                    AND Routine_Type = 'FUNCTION' ) 

for functions, and change Routine_Type for stored procedures

IF EXISTS ( SELECT  1
            FROM    Information_schema.Routines
            WHERE   Specific_schema = 'dbo'
                    AND specific_name = 'Foo'
                    AND Routine_Type = 'PROCEDURE' ) 

No, You can't do that, the only place you can call the constructor from another constructor in C# is immediately after ":" after the constructor. for example

class foo
{
    public foo(){}
    public foo(string s ) { }
    public foo (string s1, string s2) : this(s1) {....}

}

This can also be fixed by installing a node package manually.

npm install npm -g

The process of doing that will setup all the required directories.

The way to do this in .NET Core is (at the time of writing) as follows:

public async Task<IActionResult> YourAction(YourModel model)
{
    if (ModelState.IsValid)
    {
        return StatusCode(200);
    }

    return StatusCode(400);
}

The StatusCode method returns a type of StatusCodeResult which implements IActionResult and can thus be used as a return type of your action.

As a refactor, you could improve readability by using a cast of the HTTP status codes enum like:

return StatusCode((int)HttpStatusCode.OK);

Furthermore, you could also use some of the built in result types. For example:

return Ok(); // returns a 200
return BadRequest(ModelState); // returns a 400 with the ModelState as JSON

Ref. StatusCodeResult - https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.mvc.statuscoderesult?view=aspnetcore-2.1

Java support microseconds through TimeUnit enum.

Here is the java doc: Enum TimeUnit

You can get microseconds in java by this way:

long microsenconds = TimeUnit.MILLISECONDS.toMicros(System.currentTimeMillis());

You also can convert microseconds back to another time units, for example:

long seconds = TimeUnit.MICROSECONDS.toSeconds(microsenconds);

This is a diff engine for java developers, but it comes with a demo interface - you might be able to use it: https://community.emc.com/docs/DOC-5042

In case you are using eclipse to connect oracle without SID. There are two drivers to select i.e., Oracle thin driver and other is other driver. Select other drivers and enter service name in database column. Now you can connect directly using service name without SID.

Additionally, you could use just the same variable for the member of the input list which is currently accessed and for the element inside this member. However, this might even make it more (list) incomprehensible.

input = [[1, 2], [3, 4]]
[x for x in input for x in x]

First for x in input is evaluated, leading to one member list of the input, then, Python walks through the second part for x in x during which the x-value is overwritten by the current element it is accessing, then the first x defines what we want to return.

SELECT COALESCE(sum(CASE WHEN myCol THEN 1 ELSE 0 END),0) FROM <table name>

or, as you found out for yourself:

SELECT count(CASE WHEN myCol THEN 1 END) FROM <table name>

You can add a wrapper around promise functionality to return an Observable to observer.

• Creating a Lazy Observable using defer() operator which allows you to create the Observable only when the Observer subscribes.

import { of, Observable, defer } from 'rxjs'; 
import { map } from 'rxjs/operators';


function getTodos$(): Observable<any> {
  return defer(()=>{
    return fetch('https://jsonplaceholder.typicode.com/todos/1')
      .then(response => response.json())
      .then(json => {
        return json;
      })
  });
}

getTodos$().
 subscribe(
   (next)=>{
     console.log('Data is:', next);
   }
)

SSMSBoost add-in (currently free)

• keeps track on all executed statements (saves them do disk)
• regulary saves snapshot of SQL Editor contents. You keep history of the modifications of your script. Sometimes "the best" version is not the last and you want to restore the intermediate state.
• keeps track of opened tabs and allows to restore them after restart. Unsaved tabs are also restored.

+tons of other features. (I am the developer of the add-in)

Use empty (it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"

If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"

Update: as per the comments, the Map turns out to actually be a List (please work on your naming conventions). To check if a List contains an item the "normal" EL way, use JSTL fn:contains (although not explicitly documented, it works for List as well).

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"

I know it's an old post but I had the same issue today, what I did is simple : changing my script that send my playbook from my local host to the server, before sending it with maven command, I did this :

cat common_vars.yml > vars.yml
cat snapshot_vars.yml >> vars.yml
# or 
#cat release_vars.yml >> vars.yml
mvn ....

You can find a convenient one here:

https://github.com/varra4u/utils4j/blob/master/src/main/java/com/varra/util/StopWatch.java

Usage:

final StopWatch timer = new StopWatch();
System.out.println("Timer: " + timer);
System.out.println("ElapsedTime: " + timer.getElapsedTime());

Try either CopyOnWriteArrayList or CopyOnWriteArraySet depending on what you are trying to do.

To build upon Albert's answer, I like to use $COMSPEC for detecting Windows:

#!/bin/bash

if [ "$(uname)" == "Darwin" ]
then
 echo Do something under Mac OS X platform
elif [ "$(expr substr $(uname -s) 1 5)" == "Linux" ]
then
  echo Do something under Linux platform
elif [ -n "$COMSPEC" -a -x "$COMSPEC" ]
then 
  echo $0: this script does not support Windows \:\(
fi

This avoids parsing variants of Windows names for $OS, and parsing variants of uname like MINGW, Cygwin, etc.

Background: %COMSPEC% is a Windows environmental variable specifying the full path to the command processor (aka the Windows shell). The value of this variable is typically %SystemRoot%\system32\cmd.exe, which typically evaluates to C:\Windows\system32\cmd.exe .

You need to use OPENROWSET

Check this question: import-excel-spreadsheet-columns-into-sql-server-database

You can't commit empty folders in git. If you want it to show up, you need to put something in it, even just an empty file.

For example, add an empty file called .gitkeep to the folder you want to keep, then in your .gitignore file write:

# exclude everything
somefolder/*

# exception to the rule
!somefolder/.gitkeep 

Commit your .gitignore and .gitkeep files and this should resolve your issue.

As per my analysis and search on the internet also, I could not found a way to centre the image vertically centred using <div> it was possible only using <table> because table provides the following property:

valign="middle"

using System.Globalization;

LblMonth.Text = DateTime.Now.Month.ToString();

DateTimeFormatInfo dinfo = new DateTimeFormatInfo();
int month = Convert.ToInt16(LblMonth.Text);

LblMonth.Text = dinfo.GetMonthName(month);

None of these methods worked for me in .NET Core 2.2 but I was able to adapt some code I had for defining a different primary key to work for this purpose.

In the instance below I want to ensure the OutletRef field is unique:

public class ApplicationDbContext : IdentityDbContext
    {
        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<Outlet>()
                .HasIndex(o => new { o.OutletRef });
        }
    }

This adds the required unique index in the database. What it doesn't do though is provide the ability to specify a custom error message.

This is a very interesting bug. (In my opinion, it is a bug anyway) Nice find!

Regarding how to set it, I would recommend Camilo Martin's answer. But as to why, I'd like to explain this a bit if you guys don't mind.

In the CSS specs I found:

'padding'
Percentages: refer to width of containing block

… which is weird, but okay.

So, with a parent width: 210px and a child padding-top: 50%, I get a calculated/computed value of padding-top: 96.5px – which is not the expected 105px.

That is because in Windows (I'm not sure about other OSs), the size of common scrollbars is per default 17px × 100% (or 100% × 17px for horizontal bars). Those 17px are substracted before calculating the 50%, hence 50% of 193px = 96.5px.

You actually need to pass a function inside the window.setTimeout() which you want to execute after 5000 milliseconds, like this:

$(document).ready(function () {
    // Handler for .ready() called.
    window.setTimeout(function () {
        location.href = "https://www.google.co.in";
    }, 5000);
});

For More info: .setTimeout()

'Date' is your index so you want to do,

print (df.index.min())
print (df.index.max())

2014-03-13 00:00:00
2014-03-31 00:00:00

Looks like jQuery takes a guess about the datatype. It does the JSON parsing even though you're not calling getJSON()-- then when you try to call JSON.parse() on an object, you're getting the error.

Further explanation can be found in Aditya Mittal's answer.

<i class="fa" v-bind:class="cravings"></i>

and add in computed :

computed: {
    cravings: function() {
        return this.content['cravings'] ? 'fa-checkbox-marked' : 'fa-checkbox-blank-outline';
    }
}

You can use the overloaded constructor of DateTime:

DateTime utcDateTime = new DateTime(dateTime.Year, dateTime.Month, dateTime.Day, dateTime.Hour, dateTime.Minute, dateTime.Second, DateTimeKind.Utc);

I use the file *nix command to convert a unknown charset file in a utf-8 file

# -*- encoding: utf-8 -*-

# converting a unknown formatting file in utf-8

import codecs
import commands

file_location = "jumper.sub"
file_encoding = commands.getoutput('file -b --mime-encoding %s' % file_location)

file_stream = codecs.open(file_location, 'r', file_encoding)
file_output = codecs.open(file_location+"b", 'w', 'utf-8')

for l in file_stream:
    file_output.write(l)

file_stream.close()
file_output.close()

You can use my SwiftExcel library. It is especially good when performance and low memory usage come in place as it writes data directly to the file:

using (var ew = new ExcelWriter("C:\\temp\\test.xlsx"))
{
    for (var row = 1; row <= 100; row++)
    {
        for (var col = 1; col <= 10; col++)
        {
            ew.Write($"row:{row}-col:{col}", col, row);
        }
    }
}

Nuget command to install:

Install-Package SwiftExcel

It's up to the user whether they want to use new tabs or new windows, it isn't the business of the developer to modify this behaviour. I do not think you can do it.

Pet peeve of mine - I hate it when sites force me to open in a new window / tab - I am quite capable of making that decision for myself. Particularly when they do it in javascript - that is really unhelpful.

One way you can do it, is to get the slaves list from the frame that needs to be cleared and destroy or "hide" them according to your needs. To get a clear frame you can do it like this:

from tkinter import *

root = Tk()

def clear():
    list = root.grid_slaves()
    for l in list:
        l.destroy()

Label(root,text='Hello World!').grid(row=0)
Button(root,text='Clear',command=clear).grid(row=1)

root.mainloop()

You should call grid_slaves(), pack_slaves() or slaves() depending on the method you used to add the widget to the frame.

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

Somehow your requirement sounds a bit contradictory ..

group by name (which is basically a distinct on name plus readiness to aggregate) and then a distinct on IP

What do you think should happen if two people (names) worked from the same IP within the time period specified?

Did you try this?

SELECT name, COUNT(name), time, price, ip, SUM(price) 
  FROM tablename 
 WHERE time >= $yesterday AND time <$today 
GROUP BY name,ip

Appears you are having 'y' default to 1: An arrow function would be useful in 2020:

let x = (y = 1) => //insert operation with y here

Let 'x' be a function where 'y' is a parameter which would be assigned a default to '1' if it is some null or undefined value, then return some operation with y.

Isn't it smoother to make a method to be called after the creation of the EditText unit in an AlertDialog, for general use?

public static void EditTextListPicker(final Activity activity, final EditText EditTextItem, final String SelectTitle, final String[] SelectList) {
    EditTextItem.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(activity);
            builder.setTitle(SelectTitle);
            builder.setItems(SelectList, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialogInterface, int item) {
                    EditTextItem.setText(SelectList[item]);
                }
            });
            builder.create().show();
            return false;
        }
    });
}

in swift ;)

If you have Problems using this control, you might take a look here.

In addition to the other correct answers, you may want to consider scaling your values to avoid problems with floating-point arithmetic.

For example:

var result = 1.0 + 2.0;     // result === 3.0 returns true

... instead of:

var result = 0.1 + 0.2;     // result === 0.3 returns false

The expression 0.1 + 0.2 === 0.3 returns false in JavaScript, but fortunately integer arithmetic in floating-point is exact, so decimal representation errors can be avoided by scaling.

As a practical example, to avoid floating-point problems where accuracy is paramount, it is recommended¹ to handle money as an integer representing the number of cents: 2550 cents instead of 25.50 dollars.

For php 5.4 on Centos 6.10, we include these lines in php.ini

extension=/opt/remi/php54/root/usr/lib64/php/modules/pdo.so
extension=/opt/remi/php54/root/usr/lib64/php/modules/pgsql.so
extension=/opt/remi/php54/root/usr/lib64/php/modules/pdo_pgsql.so

It works.

public String substring(int beginIndex, int endIndex)

beginIndex—the begin index, inclusive.

endIndex—the end index, exclusive.

Example:

public class Test {

    public static void main(String args[]) {
        String Str = new String("Hello World");

        System.out.println(Str.substring(3, 8));
    }
 }

Output: "lo Wo"

From 3 to 7 index.

Also there is another kind of substring() method:

public String substring(int beginIndex)

beginIndex—the begin index, inclusive. Returns a sub string starting from beginIndex to the end of the main String.

Example:

public class Test {

    public static void main(String args[]) {
        String Str = new String("Hello World");

        System.out.println(Str.substring(3));
    }
}

Output: "lo World"

From 3 to the last index.

In my case, it was working in x86 but not in x64.

It quite ridiculous, but in x64 the following change had to be added before it would work:

x86 -> szDsn = "DRIVER={MICROSOFT ACCESS DRIVER (*.mdb)};
x64 -> szDsn = "DRIVER={MICROSOFT ACCESS DRIVER (*.mdb, *.accdb)};

Note the addition of *.accdb.

Similar question asked and answered using JQuery here:

Get width height of remote image from url

function getMeta(url){
  $("<img/>").attr("src", url).load(function(){
     s = {w:this.width, h:this.height};
     alert(s.w+' '+s.h);      
  }); 
}

getMeta("http://page.com/img.jpg");

you can make it using js file and ajax call. while validating data using js file we can read the text of selected dropdown

$("#dropdownid").val();   for value
$("#dropdownid").text(); for selected value

catch these into two variables and take it as inputs to ajax call for a php file

$.ajax 
   ({
     url:"callingphpfile.php",//url of fetching php  
     method:"POST", //type 
     data:"val1="+value+"&val2="+selectedtext,
     success:function(data) //return the data     
     {

}

and in php you can get it as

    if (isset($_POST["val1"])) {
    $val1= $_POST["val1"] ;
}

if (isset($_POST["val2"])) {
  $selectedtext= $_POST["val1"];
}

There are two ways to write case statements, you seem to be using a combination of the two

case a.updatedDate
    when 1760 then 'Entered on' + a.updatedDate
    when 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

or

case 
    when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
    when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.

From the documentation of the HttpWebRequest.Timeout property:

A Domain Name System (DNS) query may take up to 15 seconds to return or time out. If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request.

Is it possible that your DNS query is the cause of the timeout?

Well, if you can use Tcl/Tk in your environment, you probably should write a TCL script and use that. You might also look at wish.

1. install json-loader:

   npm i json-loader --save

2. create data folder in src:

   mkdir data

3. put your file(s) there

4. load your file

Usually, you don't want to expose any of your internal paths for how your server is structured to the outside world. What you can is make a /scripts static route in your server that fetches its files from whatever directory they happen to reside in. So, if your files are in "./node_modules/bootstrap/dist/". Then, the script tag in your pages just looks like this:

<script src="/scripts/bootstrap.min.js"></script>

If you were using express with nodejs, a static route is as simple as this:

app.use('/scripts', express.static(__dirname + '/node_modules/bootstrap/dist/'));

Then, any browser requests from /scripts/xxx.js will automatically be fetched from your dist directory at __dirname + /node_modules/bootstrap/dist/xxx.js.

Note: Newer versions of NPM put more things at the top level, not nested so deep so if you are using a newer version of NPM, then the path names will be different than indicated in the OP's question and in the current answer. But, the concept is still the same. You find out where the files are physically located on your server drive and you make an app.use() with express.static() to make a pseudo-path to those files so you aren't exposing the actual server file system organization to the client.

If you don't want to make a static route like this, then you're probably better off just copying the public scripts to a path that your web server does treat as /scripts or whatever top level designation you want to use. Usually, you can make this copying part of your build/deployment process.

If you want to make just one particular file public in a directory and not everything found in that directory with it, then you can manually create individual routes for each file rather than use express.static() such as:

<script src="/bootstrap.min.js"></script>

And the code to create a route for that

app.get('/bootstrap.min.js', function(req, res) {
    res.sendFile(__dirname + '/node_modules/bootstrap/dist/bootstrap.min.js');
});

Or, if you want to still delineate routes for scripts with /scripts, you could do this:

<script src="/scripts/bootstrap.min.js"></script>

And the code to create a route for that

app.get('/scripts/bootstrap.min.js', function(req, res) {
    res.sendFile(__dirname + '/node_modules/bootstrap/dist/bootstrap.min.js');
});

foreach ($all_address as $aa) {
    $mail->AddAddress($aa); 
}

To test if object is an instance of class a:

[yourObject isKindOfClass:[a class]]
// Returns a Boolean value that indicates whether the receiver is an instance of 
// given class or an instance of any class that inherits from that class.

or

[yourObject isMemberOfClass:[a class]]
// Returns a Boolean value that indicates whether the receiver is an instance of a 
// given class.

To get object's class name you can use NSStringFromClass function:

NSString *className = NSStringFromClass([yourObject class]);

or c-function from objective-c runtime api:

#import <objc/runtime.h>

/* ... */

const char* className = class_getName([yourObject class]);
NSLog(@"yourObject is a: %s", className);

EDIT: In Swift

if touch.view is UIPickerView {
    // touch.view is of type UIPickerView
}

Just learning this myself. I will answer the second question:

2. How to use these files? Currently I am using webpack-dev-server to run the application.

Instead of using webpack-dev-server, you can just run an "express". use npm install "express" and create a server.js in the project's root dir, something like this:

var path = require("path");
var express = require("express");

var DIST_DIR = path.join(__dirname, "build");
var PORT = 3000;
var app = express();

//Serving the files on the dist folder
app.use(express.static(DIST_DIR));

//Send index.html when the user access the web
app.get("*", function (req, res) {
  res.sendFile(path.join(DIST_DIR, "index.html"));
});

app.listen(PORT);

Then, in the package.json, add a script:

"start": "node server.js"

Finally, run the app: npm run start to start the server

A detailed example can be seen at: https://alejandronapoles.com/2016/03/12/the-simplest-webpack-and-express-setup/ (the example code is not compatible with the latest packages, but it will work with small tweaks)

Add jstl jar to your application classpath.

Your code has no problem. It does print the way you want. Alternatively, you can do this:

printf("%04x",a);

STEP 1) Start Android SDK Manager

With android command something as below,

$ /usr/local/android-studio/sdk/tools/android

STEP 2) Find API 18

STEP 3) Select Android 4.3 (API 18 ) and install packages.

@ModelAttribute is a Spring mapping of request parameters to a particular object type. so your parameters might look like userClient.username and userClient.firstName, etc. as MockMvc imitates a request from a browser, you'll need to pass in the parameters that Spring would use from a form to actually build the UserClient object.

(i think of ModelAttribute is kind of helper to construct an object from a bunch of fields that are going to come in from a form, but you may want to do some reading to get a better definition)

Redirecting stderr to stdout seems to also do the trick without any other commands/scriptblock wrappers although I can't find an explanation why it works that way..

# test.ps1

$ErrorActionPreference = "Stop"

aws s3 ls s3://xxx
echo "==> pass"

aws s3 ls s3://xxx 2>&1
echo "shouldn't be here"

This will output the following as expected (the command aws s3 ... returns $LASTEXITCODE = 255)

PS> .\test.ps1

An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied

I'm using Android Studio 0.5.2. So if your version is lower than mine my answer may not work for you.

3 ways to add a new Jar to your project:

1. Menu under Files-->Project Structure
2. Just press 'F4'
3. under Project navigation, right clink on any java library and a context menu will show then click on 'Open Library Settings'

A Project Structure window will popup.

On the left column click on 'Libraries' then look at the right pane where there is a plus sign '+' and click on it then enter the path to your new library.

Make sure the new library is under the 'project\libs\' folder otherwise you may get a broken link when you save your project source code.

I couldn't find a single answer or a section in the official Django docs that had all the information I needed to override/extend the default admin templates, so I'm writing this answer as a complete guide, hoping that it would be helpful for others in the future.

Assuming the standard Django project structure:

mysite-container/         # project container directory
    manage.py
    mysite/               # project package
        __init__.py
        admin.py
        apps.py
        settings.py
        urls.py
        wsgi.py
    app1/
    app2/
    ...
    static/
    templates/

Here's what you need to do:

1. In mysite/admin.py, create a sub-class of AdminSite:

   from django.contrib.admin import AdminSite
   
   
   class CustomAdminSite(AdminSite):
       # set values for `site_header`, `site_title`, `index_title` etc.
       site_header = 'Custom Admin Site'
       ...
   
       # extend / override admin views, such as `index()`
       def index(self, request, extra_context=None):
           extra_context = extra_context or {}
   
           # do whatever you want to do and save the values in `extra_context`
           extra_context['world'] = 'Earth'
   
           return super(CustomAdminSite, self).index(request, extra_context)
   
   
   custom_admin_site = CustomAdminSite()
   

   Make sure to import custom_admin_site in the admin.py of your apps and register your models on it to display them on your customized admin site (if you want to).

2. In mysite/apps.py, create a sub-class of AdminConfig and set default_site to admin.CustomAdminSite from the previous step:

   from django.contrib.admin.apps import AdminConfig
   
   
   class CustomAdminConfig(AdminConfig):
       default_site = 'admin.CustomAdminSite'
   

3. In mysite/settings.py, replace django.admin.site in INSTALLED_APPS with apps.CustomAdminConfig (your custom admin app config from the previous step).

4. In mysite/urls.py, replace admin.site.urls from the admin URL to custom_admin_site.urls

   from .admin import custom_admin_site
   
   
   urlpatterns = [
       ...
       path('admin/', custom_admin_site.urls),
       # for Django 1.x versions: url(r'^admin/', include(custom_admin_site.urls)),
       ...
   ]
   

5. Create the template you want to modify in your templates directory, maintaining the default Django admin templates directory structure as specified in the docs. For example, if you were modifying admin/index.html, create the file templates/admin/index.html.

   All of the existing templates can be modified this way, and their names and structures can be found in Django's source code.

6. Now you can either override the template by writing it from scratch or extend it and then override/extend specific blocks.

   For example, if you wanted to keep everything as-is but wanted to override the content block (which on the index page lists the apps and their models that you registered), add the following to templates/admin/index.html:

   {% extends 'admin/index.html' %}
   
   {% block content %}
     <h1>
       Hello, {{ world }}!
     </h1>
   {% endblock %}
   

   To preserve the original contents of a block, add {{ block.super }} wherever you want the original contents to be displayed:

   {% extends 'admin/index.html' %}
   
   {% block content %}
     <h1>
       Hello, {{ world }}!
     </h1>
     {{ block.super }}
   {% endblock %}
   

   You can also add custom styles and scripts by modifying the extrastyle and extrahead blocks.

Here is an answer based on that by Anubis (which is a better approach as it doesn't modify the headers for every request) but which is more equivalent to the code in the original question:

using Newtonsoft.Json;
...

var client = new HttpClient();
var httpRequestMessage = new HttpRequestMessage
    {
        Method = HttpMethod.Post,
        RequestUri = new Uri("https://api.clickatell.com/rest/message"),
        Headers = { 
            { HttpRequestHeader.Authorization.ToString(), "Bearer xxxxxxxxxxxxxxxxxxx" },
            { HttpRequestHeader.Accept.ToString(), "application/json" },
            { "X-Version", "1" }
        },
        Content = new StringContent(JsonConvert.SerializeObject(svm))
    };

var response = client.SendAsync(httpRequestMessage).Result;

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

This error pops up, if you try to create a web worker with data URI scheme.

var w = new Worker('data:text/javascript;charset=utf-8,onmessage%20%3D%20function()%20%7B%20postMessage(%22pong%22)%3B%20%7D'); w.postMessage('ping');

It's not allowed according to the standard: http://www.whatwg.org/specs/web-apps/current-work/multipage/workers.html#dom-worker

The hashes are just because your column width is not enough to display the "number".

About the sorting, you should review how you system region and language is configured. For the US region, Excel date input should be "5/17/2012" not "17/05/2012" (this 17-may-12).

Since you mentioned reflection in your question;

boolean isArray = myArray.getClass().isArray();
boolean isCollection = Collection.class.isAssignableFrom(myList.getClass());
boolean isMap = Map.class.isAssignableFrom(myMap.getClass());

I'm not sure that you want to send two SELECT statements in one request statement because you may not be able to access both ResultSets. The database may only return the last result set.

Multiple ResultSets

However, if you're calling a stored procedure that you know can return multiple resultsets something like this will work

CallableStatement stmt = con.prepareCall(...);
try {
...

boolean results = stmt.execute();

while (results) {
    ResultSet rs = stmt.getResultSet();
    try {
    while (rs.next()) {
        // read the data
    }
    } finally {
        try { rs.close(); } catch (Throwable ignore) {}
    }

    // are there anymore result sets?
    results = stmt.getMoreResults();
}
} finally {
    try { stmt.close(); } catch (Throwable ignore) {}
}

Multiple SQL Statements

If you're talking about multiple SQL statements and only one SELECT then your database should be able to support the one String of SQL. For example I have used something like this on Sybase

StringBuffer sql = new StringBuffer( "SET rowcount 100" );
sql.append( " SELECT * FROM tbl_books ..." );
sql.append( " SET rowcount 0" );

stmt = conn.prepareStatement( sql.toString() );

This will depend on the syntax supported by your database. In this example note the addtional spaces padding the statements so that there is white space between the staments.

In my case the cause was that I had resumed a VM with android-x86 inside. Rebooting the VM with Android-x86 and restarting the adb server fixed the problem.

The ASPX code will look something like this:

 <asp:RadioButtonList ID="rblist1" runat="server">

    <asp:ListItem Text ="Item1" Value="1" />
    <asp:ListItem Text ="Item2" Value="2" />
    <asp:ListItem Text ="Item3" Value="3" />
    <asp:ListItem Text ="Item4" Value="4" />

    </asp:RadioButtonList>

    <asp:Button ID="btn1" runat="server" OnClick="Button1_Click" Text="select value" />

And the code behind:

protected void Button1_Click(object sender, EventArgs e)
        {
            string selectedValue = rblist1.SelectedValue;
            Response.Write(selectedValue);
        }

Bjarne Stroustrup's example in his C++ FAQ suggests you are correct, and only need a definition if you take the address.

class AE {
    // ...
public:
    static const int c6 = 7;
    static const int c7 = 31;
};

const int AE::c7;   // definition

int f()
{
    const int* p1 = &AE::c6;    // error: c6 not an lvalue
    const int* p2 = &AE::c7;    // ok
    // ...
}

He says "You can take the address of a static member if (and only if) it has an out-of-class definition". Which suggests it would work otherwise. Maybe your min function invokes addresses somehow behind the scenes.

Your classes should look like this

[XmlRoot("StepList")]
public class StepList
{
    [XmlElement("Step")]
    public List<Step> Steps { get; set; }
}

public class Step
{
    [XmlElement("Name")]
    public string Name { get; set; }
    [XmlElement("Desc")]
    public string Desc { get; set; }
}

Here is my testcode.

string testData = @"<StepList>
                        <Step>
                            <Name>Name1</Name>
                            <Desc>Desc1</Desc>
                        </Step>
                        <Step>
                            <Name>Name2</Name>
                            <Desc>Desc2</Desc>
                        </Step>
                    </StepList>";

XmlSerializer serializer = new XmlSerializer(typeof(StepList));
using (TextReader reader = new StringReader(testData))
{
    StepList result = (StepList) serializer.Deserialize(reader);
}

If you want to read a text file you should load the file into a FileStream and deserialize this.

using (FileStream fileStream = new FileStream("<PathToYourFile>", FileMode.Open)) 
{
    StepList result = (StepList) serializer.Deserialize(fileStream);
}

Like other have said, span is an in-line element.

See here: http://www.w3.org/TR/CSS2/visuren.html

Additionally, you can make a span behave like a div by applying a

style="display: block; margin: 0px auto; text-align: center;"

scala> val arr = Array("Hello","World")
arr: Array[java.lang.String] = Array(Hello, World)

Depending on your use case, all the above solutions apply. This is how i usually do it however :

For server side code (e.g. a batch process) I usually load the entities and work with dynamic proxies. Usually in batch processes you need to load the data anyways at the time the service runs. I try to batch load the data instead of using the find method to save some time. Depending on the process I use optimistic or pessimistic concurrency control (I always use optimistic except for parallel execution scenarios where I need to lock some records with plain sql statements, this is rare though). Depending on the code and scenario the impact can be reduced to almost zero.

For client side scenarios, you have a few options

1. Use view models. The models should have a property UpdateStatus(unmodified-inserted-updated-deleted). It is the responsibility of the client to set the correct value to this column depending on the user actions (insert-update-delete). The server can either query the db for the original values or the client should send the original values to the server along with the changed rows. The server should attach the original values and use the UpdateStatus column for each row to decide how to handle the new values. In this scenario I always use optimistic concurrency. This will only do the insert - update - delete statements and not any selects, but it might need some clever code to walk the graph and update the entities (depends on your scenario - application). A mapper can help but does not handle the CRUD logic

2. Use a library like breeze.js that hides most of this complexity (as described in 1) and try to fit it to your use case.

Hope it helps

If you want to update / add single style in DOM Element style attribute you can use this function:

function setCssTextStyle(el, style, value) {
  var result = el.style.cssText.match(new RegExp("(?:[;\\s]|^)(" +
      style.replace("-", "\\-") + "\\s*:(.*?)(;|$))")),
    idx;
  if (result) {
    idx = result.index + result[0].indexOf(result[1]);
    el.style.cssText = el.style.cssText.substring(0, idx) +
      style + ": " + value + ";" +
      el.style.cssText.substring(idx + result[1].length);
  } else {
    el.style.cssText += " " + style + ": " + value + ";";
  }
}

style.cssText is supported for all major browsers.

Use case example:

var elem = document.getElementById("elementId");
setCssTextStyle(elem, "margin-top", "10px !important");

It depends whether you ListBox object of the System.Windows.Forms.ListBox class, which does have the ListBox.IndexFromPoint() method. But if the ListBox object is from the System.Windows.Control.Listbox class, the answer from @dark-knight (marked as correct answer) does not work.

Im running Win 10 (1903) and current versions of the .NET framework (4.8). This issue should not be version dependant though, only whether your Application is using WPF or Windows Form for the UI. See also: WPF vs Windows Form

Use This:

.modal-full {
    min-width: 100%;
    margin: 0;
}

.modal-full .modal-content {
    min-height: 100vh;
}

and so:

<div id="myModal" class="modal" role="dialog">
    <div class="modal-dialog modal-full">
        <!-- Modal content-->
        <div class="modal-content ">
            <div class="modal-header ">                    
                <button type="button" class="close" data-dismiss="modal">&times; 
                </button>
                <h4 class="modal-title">hi</h4>
            </div>
            <div class="modal-body">
                <p>Some text in the modal.</p>
            </div>
        </div>

    </div>

Depending on what exactly you require, a Server.Transfer might be a resource-cheaper alternative to Response.Redirect. More information is in Server.Transfer Vs. Response.Redirect.

Just add the onclick-attribute:

<div class="drill_cursor" onclick='alert("youClickedMe!");'>
....
</div>

It's javascript, but it's automatically bound using an html-attribute instead of manually binding it within <script> tags - maybe it does what you want.

While it might be good enough for very small projects or test pages, you should definitly consider using addEventListener (as pointed out by other answers), if you expect the code to grow and stay maintainable.

Not seeing the need for any object malarky myself. Simple have a variable which is an integer. When you start a request, increment the number. When one completes, decrement it. When it's zero, there are no requests in progress, so you're done.

$('#button').click(function() {
    var inProgress = 0;

    function handleBefore() {
        inProgress++;
    };

    function handleComplete() {
        if (!--inProgress) {
            // do what's in here when all requests have completed.
        }
    };

    $.ajax({
        beforeSend: handleBefore,
        complete: function () {
            // whatever
            handleComplete();
            // whatever
        }
    });
    $.ajax({
        beforeSend: handleBefore,
        complete: function () {
            // whatever
            handleComplete();
            // whatever
        }
    });
    $.ajax({
        beforeSend: handleBefore,
        complete: function () {
            // whatever
            handleComplete();
            // whatever
        }
    });
});

It's identical to commenting out the block, except with one important difference: Nesting is not a problem. Consider this code:

foo();
bar(x, y); /* x must not be NULL */
baz();

If I want to comment it out, I might try:

/*
foo();
bar(x, y); /* x must not be NULL */
baz();
*/

Bzzt. Syntax error! Why? Because block comments do not nest, and so (as you can see from SO's syntax highlighting) the */ after the word "NULL" terminates the comment, making the baz call not commented out, and the */ after baz a syntax error. On the other hand:

#if 0
foo();
bar(x, y); /* x must not be NULL */
baz();
#endif

Works to comment out the entire thing. And the #if 0s will nest with each other, like so:

#if 0
pre_foo();
#if 0
foo();
bar(x, y); /* x must not be NULL */
baz();
#endif
quux();
#endif

Although of course this can get a bit confusing and become a maintenance headache if not commented properly.

Simple input[name=Sex][value=M] would do pretty nice. And it's actually well-described in the standard doc:

Multiple attribute selectors can be used to refer to several attributes of an element, or even several times to the same attribute.

Here, the selector matches all SPAN elements whose "hello" attribute has exactly the value "Cleveland" and whose "goodbye" attribute has exactly the value "Columbus":

span[hello="Cleveland"][goodbye="Columbus"] { color: blue; }

As a side note, using quotation marks around an attribute value is required only if this value is not a valid identifier.

Is one just an extension?

Pretty much, yes - RFC 3339 is listed as a profile of ISO 8601. Most notably RFC 3339 specifies a complete representation of date and time (only fractional seconds are optional). The RFC also has some small, subtle differences. For example truncated representations of years with only two digits are not allowed -- RFC 3339 requires 4-digit years, and the RFC only allows a period character to be used as the decimal point for fractional seconds. The RFC also allows the "T" to be replaced by a space (or other character), while the standard only allows it to be omitted (and only when there is agreement between all parties using the representation).

I wouldn't worry too much about the differences between the two, but on the off-chance your use case runs in to them, it'd be worth your while taking a glance at:

• RFC 3339
• Wikipedia entry on ISO 8601

When you use loadbalancing it means you have several instances of tomcat and you need to divide loads.

• If you're using session replication without sticky session : Imagine you have only one user using your web app, and you have 3 tomcat instances. This user sends several requests to your app, then the loadbalancer will send some of these requests to the first tomcat instance, and send some other of these requests to the secondth instance, and other to the third.
• If you're using sticky session without replication : Imagine you have only one user using your web app, and you have 3 tomcat instances. This user sends several requests to your app, then the loadbalancer will send the first user request to one of the three tomcat instances, and all the other requests that are sent by this user during his session will be sent to the same tomcat instance. During these requests, if you shutdown or restart this tomcat instance (tomcat instance which is used) the loadbalancer sends the remaining requests to one other tomcat instance that is still running, BUT as you don't use session replication, the instance tomcat which receives the remaining requests doesn't have a copy of the user session then for this tomcat the user begin a session : the user loose his session and is disconnected from the web app although the web app is still running.
• If you're using sticky session WITH session replication : Imagine you have only one user using your web app, and you have 3 tomcat instances. This user sends several requests to your app, then the loadbalancer will send the first user request to one of the three tomcat instances, and all the other requests that are sent by this user during his session will be sent to the same tomcat instance. During these requests, if you shutdown or restart this tomcat instance (tomcat instance which is used) the loadbalancer sends the remaining requests to one other tomcat instance that is still running, as you use session replication, the instance tomcat which receives the remaining requests has a copy of the user session then the user keeps on his session : the user continue to browse your web app without being disconnected, the shutdown of the tomcat instance doesn't impact the user navigation.

There are many metrics to define similarity and distance between strings as mentioned above. I will give my 5 cents by showing an example of Jaccard similarity with Q-Grams and an example with edit distance.

The libraries

from nltk.metrics.distance import jaccard_distance
from nltk.util import ngrams
from nltk.metrics.distance  import edit_distance

Jaccard Similarity

1-jaccard_distance(set(ngrams('Apple', 2)), set(ngrams('Appel', 2)))

and we get:

0.33333333333333337

And for the Apple and Mango

1-jaccard_distance(set(ngrams('Apple', 2)), set(ngrams('Mango', 2)))

and we get:

0.0

Edit Distance

edit_distance('Apple', 'Appel')

and we get:

2

And finally,

edit_distance('Apple', 'Mango')

and we get:

5

Cosine Similarity on Q-Grams (q=2)

Another solution is to work with the textdistance library. I will provide an example of Cosine Similarity

import textdistance
1-textdistance.Cosine(qval=2).distance('Apple', 'Appel')

and we get:

0.5

The difference are:

$(document).ready(function() { is jQuery event that is fired when DOM is loaded, so it’s fired when the document structure is ready.

$(window).load() event is fired after whole content is loaded.

One thing to be aware of is that many Linux netfilter firewalls are misconfigured.

If you have something like:

-A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

-A FORWARD -p tcp -j REJECT --reject-with tcp-reset

then packet reordering can result in the firewall considering the packets invalid and thus generating resets which will then break otherwise healthy connections.

Reordering is particularly likely with a wireless network.

This should instead be:

-A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

-A FORWARD -m state --state INVALID -j DROP

-A FORWARD -p tcp -j REJECT --reject-with tcp-reset

Basically anytime you have:

... -m state --state RELATED,ESTABLISHED -j ACCEPT

it should immediately be followed by:

... -m state --state INVALID -j DROP

It's better to drop a packet then to generate a potentially protocol disrupting tcp reset. Resets are better when they're provably the correct thing to send... since this eliminates timeouts. But if there's any chance they're invalid then they can cause this sort of pain.

Try :

Configure in web config file

<system.web> <globalization culture="ja-JP" uiCulture="zh-HK" /> </system.web>

eg: DateTime dt = DateTime.ParseExact("08/21/2013", "MM/dd/yyyy", null);

It's possible that the error didn't occur in the dot product, but after. For example try this

a = np.random.randn(12,1)
b = np.random.randn(1,5)
c = np.random.randn(5,12)
d = np.dot(a,b) * c

np.dot(a,b) will be fine; however np.dot(a, b) * c is clearly wrong (12x1 X 1x5 = 12x5 which cannot element-wise multiply 5x12) but numpy will give you

ValueError: operands could not be broadcast together with shapes (12,1) (1,5)

The error is misleading; however there is an issue on that line.

Without Linq:

Ascending:

li.Sort();

Descending:

li.Sort();
li.Reverse();

More generally, I think you might want to get "top" of the rows that are sorted within a given group.

For the case of where a single value is max'd out, you have essentially sorted by only one column. However, it's often useful to hierarchically sort by multiple columns (for example: a date column and a time-of-day column).

# Answering the question of getting row with max "value".
df %>% 
  # Within each grouping of A and B values.
  group_by( A, B) %>% 
  # Sort rows in descending order by "value" column.
  arrange( desc(value) ) %>% 
  # Pick the top 1 value
  slice(1) %>% 
  # Remember to ungroup in case you want to do further work without grouping.
  ungroup()

# Answering an extension of the question of 
# getting row with the max value of the lowest "C".
df %>% 
  # Within each grouping of A and B values.
  group_by( A, B) %>% 
  # Sort rows in ascending order by C, and then within that by 
  # descending order by "value" column.
  arrange( C, desc(value) ) %>% 
  # Pick the one top row based on the sort
  slice(1) %>% 
  # Remember to ungroup in case you want to do further work without grouping.
  ungroup()

No, you can't achieve that without setting a fixed height (or using a script).

Here are 2 answers of mine, showing how to use a script to achieve something like that:

• How to get header from cards or similar to have the same height with flex box?

• Same height for flex items in the flex-direction column flex container

The idea of os.path.join() is to make your program cross-platform (linux/windows/etc).

Even one slash ruins it.

So it only makes sense when being used with some kind of a reference point like os.environ['HOME'] or os.path.dirname(__file__).

I just went through this, and all of your answers helped me toward a good solution, for me. I resisted going the route suggested by, just because I found it hard to read and comprehend.

Here's what I did. I had a BOOL being carried around in a variable called "_talkative".

When I set my default (NSUserDefaults) object, I set it as an object, as I could then test to see if it was nil:

//converting BOOL to an object so we can check on nil
[defaults setObject:@(_talkative) forKey:@"talkative"];

Then when I went to see if it existed, I used:

if ([defaults objectForKey:@"talkative"]!=nil )
  {

Then I used the object as a BOOL:

if ([defaults boolForKey:@"talkative"]) {
 ...

This seems to work in my case. It just made more visual sense to me.

For those who don't have pip installed, I found this quick script on github (works with Python 2.7.13):

import pkg_resources
distros = pkg_resources.AvailableDistributions()
for key in distros:
  print distros[key]

You can always use Unicode character, for me personally this is the most clear solution:

var space = "\u0020"

thank-you Ignacio Vazquez-Abrams

i adapted slightly for better ease of use :)

placed at top of script

NEW_LINE=$'\n'

then to use easily with other variables

variable1="test1"
variable2="test2"

As far as I know you can only join this way:

var query = from obj_i in set1
join obj_j in set2 on 
    new { 
      JoinProperty1 = obj_i.SomeField1,
      JoinProperty2 = obj_i.SomeField2,
      JoinProperty3 = obj_i.SomeField3,
      JoinProperty4 = obj_i.SomeField4
    } 
    equals 
    new { 
      JoinProperty1 = obj_j.SomeOtherField1,
      JoinProperty2 = obj_j.SomeOtherField2,
      JoinProperty3 = obj_j.SomeOtherField3,
      JoinProperty4 = obj_j.SomeOtherField4
    }

The main requirements are: Property names, types and order in the anonymous objects you're joining on must match.

You CAN'T use ANDs, ORs, etc. in joins. Just object1 equals object2.

More advanced stuff in this LinqPad example:

class c1 
    {
    public int someIntField;
    public string someStringField;
    }
    
class c2 
    {
    public Int64 someInt64Property {get;set;}
    private object someField;
    public string someStringFunction(){return someField.ToString();}
    }
    
void Main()
{
    var set1 = new List<c1>();
    var set2 = new List<c2>();
    
    var query = from obj_i in set1
    join obj_j in set2 on 
        new { 
                JoinProperty1 = (Int64) obj_i.someIntField,
                JoinProperty2 = obj_i.someStringField
            } 
        equals 
        new { 
                JoinProperty1 = obj_j.someInt64Property,
                JoinProperty2 = obj_j.someStringFunction()
            }
    select new {obj1 = obj_i, obj2 = obj_j};
}

Addressing names and property order is straightforward, addressing types can be achieved via casting/converting/parsing/calling methods etc. This might not always work with LINQ to EF or SQL or NHibernate, most method calls definitely won't work and will fail at run-time, so YMMV (Your Mileage May Vary). This is because they are copied to public read-only properties in the anonymous objects, so as long as your expression produces values of correct type the join property - you should be fine.

Here is another possible solution, using the resolve attribute of the $stateProvider or the $routeProvider. Example with $stateProvider:

.config(["$stateProvider", function ($stateProvider) {

  $stateProvider

  .state("forbidden", {
    /* ... */
  })

  .state("signIn", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.isAnonymous(); }],
    }
  })

  .state("home", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.isAuthenticated(); }],
    }
  })

  .state("admin", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.hasRole("ROLE_ADMIN"); }],
    }
  });

}])

Access resolves or rejects a promise depending on the current user rights:

.factory("Access", ["$q", "UserProfile", function ($q, UserProfile) {

  var Access = {

    OK: 200,

    // "we don't know who you are, so we can't say if you're authorized to access
    // this resource or not yet, please sign in first"
    UNAUTHORIZED: 401,

    // "we know who you are, and your profile does not allow you to access this resource"
    FORBIDDEN: 403,

    hasRole: function (role) {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$hasRole(role)) {
          return Access.OK;
        } else if (userProfile.$isAnonymous()) {
          return $q.reject(Access.UNAUTHORIZED);
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    hasAnyRole: function (roles) {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$hasAnyRole(roles)) {
          return Access.OK;
        } else if (userProfile.$isAnonymous()) {
          return $q.reject(Access.UNAUTHORIZED);
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    isAnonymous: function () {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$isAnonymous()) {
          return Access.OK;
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    isAuthenticated: function () {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$isAuthenticated()) {
          return Access.OK;
        } else {
          return $q.reject(Access.UNAUTHORIZED);
        }
      });
    }

  };

  return Access;

}])

UserProfile copies the current user properties, and implement the $hasRole, $hasAnyRole, $isAnonymous and $isAuthenticated methods logic (plus a $refresh method, explained later):

.factory("UserProfile", ["Auth", function (Auth) {

  var userProfile = {};

  var clearUserProfile = function () {
    for (var prop in userProfile) {
      if (userProfile.hasOwnProperty(prop)) {
        delete userProfile[prop];
      }
    }
  };

  var fetchUserProfile = function () {
    return Auth.getProfile().then(function (response) {
      clearUserProfile();
      return angular.extend(userProfile, response.data, {

        $refresh: fetchUserProfile,

        $hasRole: function (role) {
          return userProfile.roles.indexOf(role) >= 0;
        },

        $hasAnyRole: function (roles) {
          return !!userProfile.roles.filter(function (role) {
            return roles.indexOf(role) >= 0;
          }).length;
        },

        $isAnonymous: function () {
          return userProfile.anonymous;
        },

        $isAuthenticated: function () {
          return !userProfile.anonymous;
        }

      });
    });
  };

  return fetchUserProfile();

}])

Auth is in charge of requesting the server, to know the user profile (linked to an access token attached to the request for example):

.service("Auth", ["$http", function ($http) {

  this.getProfile = function () {
    return $http.get("api/auth");
  };

}])

The server is expected to return such a JSON object when requesting GET api/auth:

{
  "name": "John Doe", // plus any other user information
  "roles": ["ROLE_ADMIN", "ROLE_USER"], // or any other role (or no role at all, i.e. an empty array)
  "anonymous": false // or true
}

Finally, when Access rejects a promise, if using ui.router, the $stateChangeError event will be fired:

.run(["$rootScope", "Access", "$state", "$log", function ($rootScope, Access, $state, $log) {

  $rootScope.$on("$stateChangeError", function (event, toState, toParams, fromState, fromParams, error) {
    switch (error) {

    case Access.UNAUTHORIZED:
      $state.go("signIn");
      break;

    case Access.FORBIDDEN:
      $state.go("forbidden");
      break;

    default:
      $log.warn("$stateChangeError event catched");
      break;

    }
  });

}])

If using ngRoute, the $routeChangeError event will be fired:

.run(["$rootScope", "Access", "$location", "$log", function ($rootScope, Access, $location, $log) {

  $rootScope.$on("$routeChangeError", function (event, current, previous, rejection) {
    switch (rejection) {

    case Access.UNAUTHORIZED:
      $location.path("/signin");
      break;

    case Access.FORBIDDEN:
      $location.path("/forbidden");
      break;

    default:
      $log.warn("$stateChangeError event catched");
      break;

    }
  });

}])

The user profile can also be accessed in the controllers:

.state("home", {
  /* ... */
  controller: "HomeController",
  resolve: {
    userProfile: "UserProfile"
  }
})

UserProfile then contains the properties returned by the server when requesting GET api/auth:

.controller("HomeController", ["$scope", "userProfile", function ($scope, userProfile) {

  $scope.title = "Hello " + userProfile.name; // "Hello John Doe" in the example

}])

UserProfile needs to be refreshed when a user signs in or out, so that Access can handle the routes with the new user profile. You can either reload the whole page, or call UserProfile.$refresh(). Example when signing in:

.service("Auth", ["$http", function ($http) {

  /* ... */

  this.signIn = function (credentials) {
    return $http.post("api/auth", credentials).then(function (response) {
      // authentication succeeded, store the response access token somewhere (if any)
    });
  };

}])

.state("signIn", {
  /* ... */
  controller: "SignInController",
  resolve: {
    /* ... */
    userProfile: "UserProfile"
  }
})

.controller("SignInController", ["$scope", "$state", "Auth", "userProfile", function ($scope, $state, Auth, userProfile) {

  $scope.signIn = function () {
    Auth.signIn($scope.credentials).then(function () {
      // user successfully authenticated, refresh UserProfile
      return userProfile.$refresh();
    }).then(function () {
      // UserProfile is refreshed, redirect user somewhere
      $state.go("home");
    });
  };

}])

This worked for me

<p:column headerText="name" style="width:20px;"/>

Seems like just this works:

curl -I http://example.com

Look for Access-Control-Allow-Origin: * in the returned headers

If you are looking for a difference expressed as a combination of years, months, and days, I would suggest this function:

        var result = interval(date2, date1);_x000D_

        result.months = -result.months;_x000D_

    }_x000D_
    if (result.days < 0) {_x000D_
        result.months--;_x000D_
        // days = days left in date1's month, _x000D_
        //   plus days that have passed in date2's month_x000D_
        var copy1 = new Date(date1.getTime());_x000D_
        copy1.setDate(32);_x000D_
        result.days = 32-date1.getDate()-copy1.getDate()+date2.getDate();_x000D_

var date2 = new Date(2015, 5-1, 9);_x000D_
_x000D_
document.write(JSON.stringify(interval(date1, date2)));

This solution will treat leap years (29 February) and month length differences in a way we would naturally do (I think).

So for example, the interval between 28 February 2015 and 28 March 2015 will be considered exactly one month, not 28 days. If both those days are in 2016, the difference will still be exactly one month, not 29 days.

Dates with exactly the same month and day, but different year, will always have a difference of an exact number of years. So the difference between 2015-03-01 and 2016-03-01 will be exactly 1 year, not 1 year and 1 day (because of counting 365 days as 1 year).

define a shape for your edittext and give it a padding For Example

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <padding
        android:left="5dp"
        android:right="5dp"
    />
    <solid android:color="#F6F6F6" />
    <stroke
        android:width="1px"
        android:color="#C3C3C3" />

    <corners
        android:bottomLeftRadius="1dp"
        android:bottomRightRadius="1dp"
        android:topLeftRadius="1dp"
        android:topRightRadius="1dp" />
</shape>

The padding defined in this shape will help in give padding to drawableleft or right ---------------------- Apply this shape on EditView

 <EditText
            android:id="@+id/example"
            android:layout_width="fill_parent"
            android:layout_height="36dp"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:background="@drawable/shape2"
            android:drawableLeft="@drawable/icon1"
            android:drawablePadding="@dimen/txtDrwblPadding"
            android:ems="10"
         />

using that defined shape as background will give your EditText some style plus margin to drawableLeft.

You could use row_factory, as in the example in the docs:

import sqlite3

def dict_factory(cursor, row):
    d = {}
    for idx, col in enumerate(cursor.description):
        d[col[0]] = row[idx]
    return d

con = sqlite3.connect(":memory:")
con.row_factory = dict_factory
cur = con.cursor()
cur.execute("select 1 as a")
print cur.fetchone()["a"]

or follow the advice that's given right after this example in the docs:

If returning a tuple doesn’t suffice and you want name-based access to columns, you should consider setting row_factory to the highly-optimized sqlite3.Row type. Row provides both index-based and case-insensitive name-based access to columns with almost no memory overhead. It will probably be better than your own custom dictionary-based approach or even a db_row based solution.

It is confirmed that Windows 7 and newer versions (at least 64bit or both) do not use system speaker and instead they route the call to the default sound device.

So, using system.beep() in win7/8/10 will not produce sound using internal system speaker. Instead, you'll get a beep sound from external speakers if they are available.

Little performance tip if somebody has a datastore kind of service with key -> value pairs:

If you have a service called dataStore, you can update a timestamp whenever your big data object changes. This way instead of deep watching the whole object, you are only watching a timestamp for change.

app.factory('dataStore', function () {

    var store = { data: [], change: [] };

    // when storing the data, updating the timestamp
    store.setData = function(key, data){
        store.data[key] = data;
        store.setChange(key);
    }

    // get the change to watch
    store.getChange = function(key){
        return store.change[key];
    }

    // set the change
    store.setChange = function(key){
        store.change[key] = new Date().getTime();
    }

});

And in a directive you are only watching the timestamp to change

app.directive("myDir", function ($scope, dataStore) {
    $scope.dataStore = dataStore;
    $scope.$watch('dataStore.getChange("myKey")', function(newVal, oldVal){
        if(newVal !== oldVal && newVal){
            // Data changed
        }
    });
});

You can also use the matrix command, to create a matrix with n lines and m columns, filled with zeros.

matrix(0, n, m)

var dateTimeString = "21?-?10?-?2014? ?15?:?40?:?30";
dateTimeString = Regex.Replace(dateTimeString, @"[^\u0000-\u007F]", string.Empty);

var inputFormat = "dd-MM-yyyy HH:mm:ss";
var outputFormat = "yyyy-MM-dd HH:mm:ss";
var dateTime = DateTime.ParseExact(dateTimeString, inputFormat, CultureInfo.InvariantCulture);
var output = dateTime.ToString(outputFormat);

Console.WriteLine(output);

Try this, it works for me.

I often want different columns to have different formats. Here is how I print a simple 2D array using some variety in the formatting by converting (slices of) my NumPy array to a tuple:

import numpy as np
dat = np.random.random((10,11))*100  # Array of random values between 0 and 100
print(dat)                           # Lines get truncated and are hard to read
for i in range(10):
    print((4*"%6.2f"+7*"%9.4f") % tuple(dat[i,:]))

A proper REST API should have below components in response

1. Status Code
2. Response Body
3. Location to the resource which was altered(for example, if a resource was created, client would be interested to know the url of that location)

The main purpose of ResponseEntity was to provide the option 3, rest options could be achieved without ResponseEntity.

So if you want to provide the location of resource then using ResponseEntity would be better else it can be avoided.

Consider an example where a API is modified to provide all the options mentioned

// Step 1 - Without any options provided
@RequestMapping(value="/{id}", method=RequestMethod.GET)
public @ResponseBody Spittle spittleById(@PathVariable long id) {
  return spittleRepository.findOne(id);
}

// Step 2- We need to handle exception scenarios, as step 1 only caters happy path.
@ExceptionHandler(SpittleNotFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
public Error spittleNotFound(SpittleNotFoundException e) {
  long spittleId = e.getSpittleId();
  return new Error(4, "Spittle [" + spittleId + "] not found");
}

// Step 3 - Now we will alter the service method, **if you want to provide location**
@RequestMapping(
    method=RequestMethod.POST
    consumes="application/json")
public ResponseEntity<Spittle> saveSpittle(
    @RequestBody Spittle spittle,
    UriComponentsBuilder ucb) {

  Spittle spittle = spittleRepository.save(spittle);
  HttpHeaders headers = new HttpHeaders();
  URI locationUri =
  ucb.path("/spittles/")
      .path(String.valueOf(spittle.getId()))
      .build()
      .toUri();
  headers.setLocation(locationUri);
  ResponseEntity<Spittle> responseEntity =
      new ResponseEntity<Spittle>(
          spittle, headers, HttpStatus.CREATED)
  return responseEntity;
}

// Step4 - If you are not interested to provide the url location, you can omit ResponseEntity and go with
@RequestMapping(
    method=RequestMethod.POST
    consumes="application/json")
@ResponseStatus(HttpStatus.CREATED)
public Spittle saveSpittle(@RequestBody Spittle spittle) {
  return spittleRepository.save(spittle);
}

I was trying to implement pandas append functionality in pyspark and what I created a custom function where we can concat 2 or more data frame even they are having different no. of columns only condition is if dataframes have identical name then their datatype should be same/match.

I have written a custom function to merge 2 dataframes.

def append_dfs(df1,df2):
    list1 = df1.columns
    list2 = df2.columns
    for col in list2:
        if(col not in list1):
            df1 = df1.withColumn(col, F.lit(None))
    for col in list1:
        if(col not in list2):
            df2 = df2.withColumn(col, F.lit(None))
    return df1.unionByName(df2)

usage:

1. concate 2 dataframes

   final_df = append_dfs(df1,df2)

2. 1. concate more than 2(say3) dataframes

   final_df = append_dfs(append_dfs(df1,df2),df3)

example:

df1:

df2:

result=append_dfs(df1,df2)

result :

Hope this will useful.

You can do this using cross apply

SELECT c.BalanceDue AS BalanceDue
FROM Invoices
cross apply (select (InvoiceTotal - PaymentTotal - CreditTotal) as BalanceDue) as c
WHERE  c.BalanceDue  > 0;

If you've got tags (and you should), you can open a file from the command line just by the name of the class or method or c function, with "vim -t DBPlaylist", and within vim with ":tag ShowList".

For a structure definition that is to be used across more than one source file, you should definitely put it in a header file. Then include that header file in any source file that needs the structure.

The extern declaration is not used for structure definitions, but is instead used for variable declarations (that is, some data value with a structure type that you have defined). If you want to use the same variable across more than one source file, declare it as extern in a header file like:

extern struct a myAValue;

Then, in one source file, define the actual variable:

struct a myAValue;

If you forget to do this or accidentally define it in two source files, the linker will let you know about this.

I know this is an old answer but here is what I usually do:

CSS:

.form-control-inline {
   width: auto;
   float:left;
   margin-right: 5px;
}

Then wrap the fields you want to be inlined in a div and add .form-control-inline to the input, example:

HTML

<label class="control-label">Date of birth:</label>
<div>
<select class="form-control form-control-inline" name="year"> ... </select>
<select class="form-control form-control-inline" name="month"> ... </select>
<select class="form-control form-control-inline" name="day"> ... </select>
</div>

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

If the performance hit of the default constructor isn't an issue, the please, for the love of god, go with the more readable version.

:)

I like the following:

public String readLine(String tPromptString) {
    byte[] tBuffer = new byte[256];
    int tPos = 0;
    System.out.print(tPromptString);

    while(true) {
        byte tNextByte = readByte();
        if(tNextByte == 10) {
            return new String(tBuffer, 0, tPos);
        }

        if(tNextByte != 13) {
            tBuffer[tPos] = tNextByte;
            ++tPos;
        }
    }
}

and for example, I would do:

String name = this.readLine("What is your name?")

Just in case above solutions didn't work:

1. Get the port your process is listening to:

   $ ps ax | grep python

2. Kill the Process

   $ kill PROCESS_NAME

Visual Studio 2008 does have a designer that allows you to add FK's. Just right-click the table... Table Properties, then go to the "Add Relations" section.
