Or, even cleaner:

when(mockFoo.someMethod()).thenReturn(obj1, obj2);

The accurate way is to use the __FUNCTION__ predefined magic constant.

Example:

class Test {
    function MethodA(){
        echo __FUNCTION__;
    }
}

Result: MethodA.

I think one of the Advantages of code first is that you can back up all the changes you've made to a version control system like Git. Because all your tables and relationships are stored in what are essentially just classes, you can go back in time and see what the structure of your database was before.

You can ask for flags using checkboxes then do something like this:

var userInput = formInput;
var flags = '';
if(formGlobalCheckboxChecked) flags += 'g';
if(formCaseICheckboxChecked) flags += 'i';
var reg = new RegExp(userInput, flags);

To check multiple values, you can use numpy.in1d(), which is an element-wise function version of the python keyword in. If your data is sorted, you can use numpy.searchsorted():

import numpy as np
data = np.array([1,4,5,5,6,8,8,9])
values = [2,3,4,6,7]
print np.in1d(values, data)

index = np.searchsorted(data, values)
print data[index] == values

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

Given an activated Python 3.6 virtualenv in somepath/venv, the following aliases resolved the various issues on a macOS Sierra where pip insisted on pointing to Apple's 2.7 Python.

alias pip='python somepath/venv/lib/python3.6/site-packages/pip/__main__.py'

This didn't work so well when I had to do sudo pip as the root user doesn't know anything about my alias or the virtualenv, so I had to add an extra alias to handle this as well. It's a hack, but it works, and I know what it does:

alias sudopip='sudo somepath/venv/bin/python somepath/venv/lib/python3.6/site-packages/pip/__main__.py'

background:

pip3 did not exist to start (command not found) with and which pip would return /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/pip, the Apple Python.

Python 3.6 was installed via macports.

After activation of the 3.6 virtualenv I wanted to work with, which python would return somepath/venv/bin/python

Somehow pip install would do the right thing and hit my virtualenv, but pip list would rattle off Python 2.7 packages.

For Python, this is batting way beneath my expectations in terms of beginner-friendliness.

Both the shell and C one-line constructs work (ruby 1.9.3p429):

# Shell format
irb(main):022:0> true && "Yes" || "No"
=> "Yes"
irb(main):023:0> false && "Yes" || "No"
=> "No"

# C format
irb(main):024:0> true ? "Yes" : "No"
=> "Yes"
irb(main):025:0> false ? "Yes" : "No"
=> "No"

Auth::user()->products->sum('price');

The documentation is a little light for some of the Collection methods but all the query builder aggregates are seemingly available besides avg() that can be found at http://laravel.com/docs/queries#aggregates.

For portability, try this:

#ifdef _WIN32
#include <conio.h>
#else
#include <stdio.h>
#define clrscr() printf("\e[1;1H\e[2J")
#endif

Then simply call clrscr(). On Windows, it will use conio.h's clrscr(), and on Linux, it will use ANSI escape codes.

If you really want to do it "properly", you can eliminate the middlemen (conio, printf, etc.) and do it with just the low-level system tools (prepare for a massive code-dump):

#ifdef _WIN32
#define WIN32_LEAN_AND_MEAN
#include <windows.h>

void ClearScreen()
{
  HANDLE                     hStdOut;
  CONSOLE_SCREEN_BUFFER_INFO csbi;
  DWORD                      count;
  DWORD                      cellCount;
  COORD                      homeCoords = { 0, 0 };

  hStdOut = GetStdHandle( STD_OUTPUT_HANDLE );
  if (hStdOut == INVALID_HANDLE_VALUE) return;

  /* Get the number of cells in the current buffer */
  if (!GetConsoleScreenBufferInfo( hStdOut, &csbi )) return;
  cellCount = csbi.dwSize.X *csbi.dwSize.Y;

  /* Fill the entire buffer with spaces */
  if (!FillConsoleOutputCharacter(
    hStdOut,
    (TCHAR) ' ',
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Fill the entire buffer with the current colors and attributes */
  if (!FillConsoleOutputAttribute(
    hStdOut,
    csbi.wAttributes,
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Move the cursor home */
  SetConsoleCursorPosition( hStdOut, homeCoords );
}

#else // !_WIN32
#include <unistd.h>
#include <term.h>

void ClearScreen()
{
  if (!cur_term)
  {
     int result;
     setupterm( NULL, STDOUT_FILENO, &result );
     if (result <= 0) return;
  }

   putp( tigetstr( "clear" ) );
}
#endif

There's one reason to use an out param which has not already been mentioned: the calling method is obliged to receive it. If your method produces a value which the caller should not discard, making it an out forces the caller to specifically accept it:

 Method1();  // Return values can be discard quite easily, even accidentally

 int  resultCode;
 Method2(out resultCode);  // Out params are a little harder to ignore

Of course the caller can still ignore the value in an out param, but you've called their attention to it.

This is a rare need; more often, you should use an exception for a genuine problem or return an object with state information for an "FYI", but there could be circumstances where this is important.

You can use below class for validation:

public class PasswordValidator{

  private Pattern pattern;
  private Matcher matcher;

  private static final String PASSWORD_PATTERN =
          "((?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%]).{6,20})";

  public PasswordValidator(){
      pattern = Pattern.compile(PASSWORD_PATTERN);
  }

  /**
   * Validate password with regular expression
   * @param password password for validation
   * @return true valid password, false invalid password
   */
  public boolean validate(final String password){

      matcher = pattern.matcher(password);
      return matcher.matches();

  }
}

where 6 and 20 are minimum and maximum length for the password.

The other difference is that

template<class T> ...

is allowed, but

template<struct T> ...

is not.

You cannot use Set Transaction Isolation Level Read Uncommitted in a View (you can only have one script in there in fact), so you would have to use (nolock) if dirty rows should be included.

There is no 100% solution to delete browser cookies.

The problem is that cookies are uniquely identified by not just by their key "name" but also their "domain" and "path".

Without knowing the "domain" and "path" of a cookie, you cannot reliably delete it. This information is not available through JavaScript's document.cookie. It's not available through the HTTP Cookie header either!

However, if you know the name, path and domain of a cookie, then you can clear it by setting an empty cookie with an expiry date in the past, for example:

function clearCookie(name, domain, path){
    var domain = domain || document.domain;
    var path = path || "/";
    document.cookie = name + "=; expires=" + +new Date + "; domain=" + domain + "; path=" + path;
};

You can also use := construct to assign and decide on action in one step. Consider following example:

# Example of setting default server and reporting it's status

server=$1
if [[ ${server:=localhost} =~ [a-z] ]]      # 'localhost' assigned here to $server
then    echo "server is localhost"          # echo is triggered since letters were found in $server
else
        echo "server was set" # numbers were passed
fi

If $1 is not empty, localhost will be assigned to server in the if condition field, trigger match and report match result. In this way you can assign on the fly and trigger appropriate action.

Runtime.getRuntime().exec allocates the process with the same amount of memory as the main. If you had you heap set to 1GB and try to exec then it will allocate another 1GB for that process to run.

You need to commit at least one time on master before creating a new branch.

I think you want to open the ZipFile, which returns a file-like object, rather than read:

There is no advantage of using one vs the other, but, there is a specific case where throw won't work. However, those cases can be fixed.

Any time you are inside of a promise callback, you can use throw. However, if you're in any other asynchronous callback, you must use reject.

For example, this won't trigger the catch:

new Promise(function() {
  setTimeout(function() {
    throw 'or nah';
    // return Promise.reject('or nah'); also won't work
  }, 1000);
}).catch(function(e) {
  console.log(e); // doesn't happen
});

Instead you're left with an unresolved promise and an uncaught exception. That is a case where you would want to instead use reject. However, you could fix this in two ways.

1. by using the original Promise's reject function inside the timeout:

new Promise(function(resolve, reject) {
  setTimeout(function() {
    reject('or nah');
  }, 1000);
}).catch(function(e) {
  console.log(e); // works!
});

2. by promisifying the timeout:

function timeout(duration) { // Thanks joews
  return new Promise(function(resolve) {
    setTimeout(resolve, duration);
  });
}

timeout(1000).then(function() {
  throw 'worky!';
  // return Promise.reject('worky'); also works
}).catch(function(e) {
  console.log(e); // 'worky!'
});

Don't clone, fetch instead. In the repo:

git init
git remote add origin $url_of_clone_source
git fetch origin
git checkout -b master --track origin/master # origin/master is clone's default

Then you can reset the tree to get the commit you want:

git reset origin/master # or whatever commit you think is proper...

and you are like you cloned.

The interesting question here (and the one without answer): How to find out which commit your naked tree was based on, hence to which position to reset to.

I have had the same problem and came acrosse this site.

the solution to just set another "filename" in the

... for output as ... command was very simple and useful.

in addition (beyond the Application.GetSaveAsFilename() Dialog)

it is very simple to set a** new filename** just using

the replace command, so you may change the filename/extension

eg. (as from the first post)

sFileName = "C:\filelocation"
iFileNum = FreeFile

Open sFileName For Input As iFileNum
content = (...edit the content) 

Close iFileNum

now just set:

newFilename = replace(sFilename, ".txt", ".csv") to change the extension

or

newFilename = replace(sFilename, ".", "_edit.") for a differrent filename

and then just as before

iFileNum = FreeFile
Open newFileName For Output As iFileNum

Print #iFileNum, content
Close iFileNum 

I surfed over an hour to find out how to rename a txt-file,

with many different solutions, but it could be sooo easy :)

I just ran out of stack at work, it was a database and it was running some threads, basically the previous developer had thrown a big array on the stack, and the stack was low anyway. The software was compiled using Microsoft Visual Studio 2015.

Even though the thread had run out of stack, it silently failed and continued on, it only stack overflowed when it came to access the contents of the data on the stack.

The best advice i can give is to not declare arrays on the stack - especially in complex applications and particularly in threads, instead use heap. That's what it's there for ;)

Also just keep in mind it may not fail immediately when declaring the stack, but only on access. My guess is that the compiler declares stack under windows "optimistically", i.e. it will assume that the stack has been declared and is sufficiently sized until it comes to use it and then finds out that the stack isn't there.

Different operating systems may have different stack declaration policies. Please leave a comment if you know what these policies are.

var array = [];

//length array now = 0
array[array.length] = 'hello';
//length array now = 1
//            0
//array = ['hello'];//length = 1

steps 1 in the user variable and system variable

  C:\Program Files\nodejs

then check both node -v and the npm -v then try to update the the npm i -g npm

function myFunction(arg) {
    alert(arg.var1 + ' ' + arg.var2 + ' ' + arg.var3);
}

myFunction ({ var1: "Option 1", var2: "Option 2", var3: "Option 3" });

I just wondered, why col-xs-6 did not work for me but then I found the answer in the Bootstrap 4 documentation. The class prefix for extra small devices is now col- while in the previous versions it was col-xs.

https://getbootstrap.com/docs/4.1/layout/grid/#grid-options

Bootstrap 4 dropped all col-xs-* classes, so use col-* instead. For example col-xs-6 replaced by col-6.

You can record a macro that removes the first blank line, and positions the cursor correctly for the second line. Then you can repeat executing that macro.

SELECT
  student.firstname,
  student.lastname,
  exam.name,
  exam.date,
  grade.grade
FROM grade
 INNER JOIN student
   ON student.studentId = grade.fk_studentId
 INNER JOIN exam
   ON exam.examId = grade.fk_examId
 GROUP BY grade.gradeId
 ORDER BY exam.date

Install the package python-tk like

There is no such thing as importing in MS SQL. I understand what you mean. It is so simple. Whenever you get/have a something.SQL file, you should just double click and it will directly open in your MS SQL Studio.

I was also interested in this, so I did a little performance comparison (using perfplot, a pet project of mine). Result:

y = np.bincount(a)
ii = np.nonzero(y)[0]
out = np.vstack((ii, y[ii])).T

is by far the fastest. (Note the log-scaling.)

Code to generate the plot:

import numpy as np
import pandas as pd
import perfplot
from scipy.stats import itemfreq


def bincount(a):
    y = np.bincount(a)
    ii = np.nonzero(y)[0]
    return np.vstack((ii, y[ii])).T


def unique(a):
    unique, counts = np.unique(a, return_counts=True)
    return np.asarray((unique, counts)).T


def unique_count(a):
    unique, inverse = np.unique(a, return_inverse=True)
    count = np.zeros(len(unique), np.int)
    np.add.at(count, inverse, 1)
    return np.vstack((unique, count)).T


def pandas_value_counts(a):
    out = pd.value_counts(pd.Series(a))
    out.sort_index(inplace=True)
    out = np.stack([out.keys().values, out.values]).T
    return out


perfplot.show(
    setup=lambda n: np.random.randint(0, 1000, n),
    kernels=[bincount, unique, itemfreq, unique_count, pandas_value_counts],
    n_range=[2 ** k for k in range(26)],
    logx=True,
    logy=True,
    xlabel="len(a)",
)

WordPress

If you work in the wordpress environment, Wordpress sets the error level in file wp-includes/load.php in function wp_debug_mode(). So you have to change the level AFTER this function has been called ( in a file not checked into git so that's development only ), or either modify directly the error_reporting() call

Edit: Use printf("val = 0x%" PRIx64 "\n", val); instead.

Try printf("val = 0x%llx\n", val);. See the printf manpage:

ll (ell-ell). A following integer conversion corresponds to a long long int or unsigned long long int argument, or a following n conversion corresponds to a pointer to a long long int argument.

Edit: Even better is what @M_Oehm wrote: There is a specific macro for that, because unit64_t is not always a unsigned long long: PRIx64 see also this stackoverflow answer

To deserialize the response need to use HashMap:

String resp = ...//String output from your source

Gson gson = new GsonBuilder().create();
gson.fromJson(resp,TheResponse.class);

class TheResponse{
 HashMap<String,Song> songs;
}

class Song{
  String id;
  String pos;
}

I'm using Styled Components and created a helper function for myself.

It takes the given Android elevation and creates a fairly equivalent iOS shadow.

stylingTools.js

import { css } from 'styled-components/native';

/*
 REMINDER!!!!!!!!!!!!!
 Shadows do not show up on iOS if `overflow: hidden` is used.
 https://react-native.canny.io/feature-requests/p/shadow-does-not-appear-if-overflow-hidden-is-set-on-ios
*/

// eslint-disable-next-line import/prefer-default-export
export const crossPlatformElevation = (elevation: number = 0) => css`
  /* Android - native default is 4, we're setting to 0 to match iOS. */
  elevation: ${elevation};

  /* iOS - default is no shadow. Only add if above zero */
  ${elevation > 0
    && css`
      shadow-color: black;
      shadow-offset: 0px ${0.5 * elevation}px;
      shadow-opacity: 0.3;
      shadow-radius: ${0.8 * elevation}px;
    `}
`;

To use

import styled from 'styled-components/native';
import { crossPlatformElevation } from "../../lib/stylingTools";

export const ContentContainer = styled.View`
  background: white;
  ${crossPlatformElevation(10)};
`;

You can't use a class's generic type parameters in static methods or static fields. The class's type parameters are only in scope for instance methods and instance fields. For static fields and static methods, they are shared among all instances of the class, even instances of different type parameters, so obviously they cannot depend on a particular type parameter.

It doesn't seem like your problem should require using the class's type parameter. If you describe what you are trying to do in more detail, maybe we can help you find a better way to do it.

ALTER TABLE `{$installer->getTable('sales/quote_payment')}`
ADD `custom_field_one` VARCHAR( 255 ) NOT NULL,
    ADD `custom_field_two` VARCHAR( 255 ) NOT NULL;

Add backtick i.e. " ` " properly. Write your getTable name and column name between backtick.

How about streams?

public boolean checkFieldsIsNull(Object instance, List<String> fieldNames) {

    return fieldNames.stream().allMatch(field -> {
        try {
            return Objects.isNull(instance.getClass().getDeclaredField(field).get(instance));
        } catch (IllegalAccessException | NoSuchFieldException e) {
            return true;//You can throw RuntimeException if need.
        }
    });
}

The tabularx package gives you

1. the total width as a first parameter, and
2. a new column type X, all X columns will grow to fill up the total width.

For your example:

\usepackage{tabularx}
% ...    
\begin{document}
% ...

\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF &  simulation & jsp\\
\hline
\end{tabularx}

 @Html.TextBoxFor(m => m.Age, new { @Value = "12" }) 

If you want it to be a hidden field

 @Html.TextBoxFor(m => m.Age, new { @Value = "12",@type="hidden" }) 

Use the Office FileDialog object to have the user pick a file from the filesystem. Add a reference in your VB project or in the VBA editor to Microsoft Office Library and look in the help. This is much better than having people enter full paths.

Here is an example using msoFileDialogFilePicker to allow the user to choose multiple files. You could also use msoFileDialogOpen.

'Note: this is Excel VBA code
Public Sub LogReader()
    Dim Pos As Long
    Dim Dialog As Office.FileDialog
    Set Dialog = Application.FileDialog(msoFileDialogFilePicker)

    With Dialog
        .AllowMultiSelect = True
        .ButtonName = "C&onvert"
        .Filters.Clear
        .Filters.Add "Log Files", "*.log", 1
        .Title = "Convert Logs to Excel Files"
        .InitialFileName = "C:\InitialPath\"
        .InitialView = msoFileDialogViewList

        If .Show Then
            For Pos = 1 To .SelectedItems.Count
                LogRead .SelectedItems.Item(Pos) ' process each file
            Next
        End If
    End With
End Sub

There are lots of options, so you'll need to see the full help files to understand all that is possible. You could start with Office 2007 FileDialog object (of course, you'll need to find the correct help for the version you're using).

"JSON has a special value called null which can be set on any type of data including arrays, objects, number and boolean types."

"The JSON empty concept applies for arrays and objects...Data object does not have a concept of empty lists. Hence, no action is taken on the data object for those properties."

Here is my source.

What you are after is called partial function application.

Don't be fooled by those that don't understand the subtle difference between that and currying, they are different.

Partial function application can be used to implement, but is not currying. Here is a quote from a blog post on the difference:

Where partial application takes a function and from it builds a function which takes fewer arguments, currying builds functions which take multiple arguments by composition of functions which each take a single argument.

This has already been answered, see this question for your answer: How can I pre-set arguments in JavaScript function call?

Example:

var fr = partial(f, 1, 2, 3);

// now, when you invoke fr() it will invoke f(1,2,3)
fr();

Again, see that question for the details.

Git clone has an option (--no-checkout or -n) that does what you want.

In your list of commands, just change:

git clone <path>

To this:

git clone --no-checkout <path>

You can then use the sparse checkout as stated in the question.

Here is an example of how to time a function using timeit:

import timeit

def time_this(n):
    return [str(i) for i in range(n)]

timeit.timeit(lambda: time_this(n=5000), number=1000)

This will return the time in seconds it took to execute the time_this() function 1000 times.

Dont forget to add user agent since some server will block request if there's no server agent..(you would get Forbidden resource response) example :

curl -X POST -A 'Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0' -d "field=acaca&name=afadxx" https://example.com

What is the utility of an only one Ampersand? This morning, I made a launcher in the XFCE panel (in Manjaro+XFCE) to launch 2 passwords managers simultaneously:

sh -c "keepassx && password-gorilla"
or
sh -c "keepassx; password-gorilla"

But it does not work as I want. I.E., the first app starts but the second starts only when the previous is closed

However, I found that (with only one ampersand):

sh -c "keepassx & password-gorilla"

and it works as I want now...

SELECT P.*
FROM primary_table P
LEFT JOIN secondary_table S on P.id = S.p_id
WHERE S.p_id IS NULL

Because the condition is never true. i.e. count !=100 never executes when you put count=count+3 or count =count+9. try this out..while count<100

Have you tried using jQuery's ajax request? As of version 1.3 jQuery supports certain types of cross domain ajax requests.

Quoting from the reference above:

Note: All remote (not on the same domain) requests should be specified as GET when 'script' or 'jsonp' is the dataType (because it loads script using a DOM script tag). Ajax options that require an XMLHttpRequest object are not available for these requests. The complete and success functions are called on completion, but do not receive an XHR object; the beforeSend and dataFilter functions are not called.

As of jQuery 1.2, you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". jQuery automatically replaces the ? with the correct method name to call, calling your specified callback. Or, if you set the dataType to "jsonp" a callback will be automatically added to your Ajax request.

You can avoid declaration of global variables by adding them directly to the global object:

(function(global) {

  ...

  global.varName = someValue;

  ...

}(this));

A disadvantage of this method is that global.varName won't exist until that specific line of code is executed, but that can be easily worked around.

You might also consider an application architecture where such globals are held in a closure common to all functions that need them, or as properties of a suitably accessible data storage object.

Update

You can now use select with the where selection helper. select_if is superceded, but still functional as of dplyr 1.0.2. (thanks to @mcstrother for bringing this to attention).

library(dplyr)
temp <- data.frame(x = 1:5, y = c(1,2,NA,4, 5), z = rep(NA, 5))
not_all_na <- function(x) any(!is.na(x))
not_any_na <- function(x) all(!is.na(x))

> temp
  x  y  z
1 1  1 NA
2 2  2 NA
3 3 NA NA
4 4  4 NA
5 5  5 NA

> temp %>% select(where(not_all_na))
  x  y
1 1  1
2 2  2
3 3 NA
4 4  4
5 5  5

> temp %>% select(where(not_any_na))
  x
1 1
2 2
3 3
4 4
5 5

Old Answer

dplyr now has a select_if verb that may be helpful here:

> temp
  x  y  z
1 1  1 NA
2 2  2 NA
3 3 NA NA
4 4  4 NA
5 5  5 NA

> temp %>% select_if(not_all_na)
  x  y
1 1  1
2 2  2
3 3 NA
4 4  4
5 5  5

> temp %>% select_if(not_any_na)
  x
1 1
2 2
3 3
4 4
5 5

<? is disabled by default in newer versions. You can enable this like described Enabling Short Tags in PHP.

Theoretically, yes. Practice, not. Most kernels (incl. linux) doesn't allow you a second bind() to an already allocated port. It weren't a really big patch to make this allowed.

Conceptionally, we should differentiate between socket and port. Sockets are bidirectional communication endpoints, i.e. "things" where we can send and receive bytes. It is a conceptional thing, there is no such field in a packet header named "socket".

Port is an identifier which is capable to identify a socket. In case of the TCP, a port is a 16 bit integer, but there are other protocols as well (for example, on unix sockets, a "port" is essentially a string).

The main problem is the following: if an incoming packet arrives, the kernel can identify its socket by its destination port number. It is a most common way, but it is not the only possibility:

• Sockets can be identified by the destination IP of the incoming packets. This is the case, for example, if we have a server using two IPs simultanously. Then we can run, for example, different webservers on the same ports, but on the different IPs.
• Sockets can be identified by their source port and ip as well. This is the case in many load balancing configurations.

Because you are working on an application server, it will be able to do that.

Need to make sure once switched into a frame, need to switch back to default content for accessing webelements in another frames. As Webdriver tend to find the new frame inside the current frame.

driver.switchTo().defaultContent()

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

Git GUI has a PUSH button - pardon the pun, and the dialog box it opens has a checkbox for tags.

I pushed a branch from the command line, without tags, and then tried again pushing the branch using the --follow-tags option descibed above. The option is described as following annotated tags. My tags were simple tags.

I'd fixed something, tagged the commit with the fix in, (so colleagues can cherry pick the fix,) then changed the software version number and tagged the release I created (so colleagues can clone that release).

Git returned saying everything was up-to-date. It did not send the tags! Perhaps because the tags weren't annotated. Perhaps because there was nothing new on the branch.

When I did a similar push with Git GUI, the tags were sent.

For the time being, I am going to be pushing my changes to my remotes with Git GUI and not with the command line and --follow-tags.

I got this error message because while coding my project auto update compile version in my build.gradle file :

android {
    ...
    buildToolsVersion "23.0.2"
    ...
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:design:23.4.0' }

Solve it by correcting the version:

android {
        ...
        buildToolsVersion "23.0.2"
        ...
    }

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
}

Putting *args and/or **kwargs as the last items in your function definition’s argument list allows that function to accept an arbitrary number of arguments and/or keyword arguments.

For example, if you wanted to write a function that returned the sum of all its arguments, no matter how many you supply, you could write it like this:

def my_sum(*args):
    return sum(args)

It’s probably more commonly used in object-oriented programming, when you’re overriding a function, and want to call the original function with whatever arguments the user passes in.

You don’t actually have to call them args and kwargs, that’s just a convention. It’s the * and ** that do the magic.

The official Python documentation has a more in-depth look.

The margins vary depending on the printer. In Windows GDI, you call the following functions to get the built-in margins, the "no-print zone":

GetDeviceCaps(hdc, PHYSICALWIDTH);
GetDeviceCaps(hdc, PHYSICALHEIGHT);
GetDeviceCaps(hdc, PHYSICALOFFSETX);
GetDeviceCaps(hdc, PHYSICALOFFSETY);

Printing right to the edge is called a "bleed" in the printing industry. The only laser printer I ever knew to print right to the edge was the Xerox 9700: 120 ppm, $500K in 1980.

                       child: Align(
                          alignment: Alignment.center,
                          child: Text(
                            'Text here',
                            textAlign: TextAlign.center,                          
                          ),
                        ),

This produced the best result for me.

You may be forgetting something. Before #include <iostream>, write #include <stdafx.h> and maybe that will help. Then, when you are done writing, click test, than click output from build, then when it is done processing/compiling, press Ctrl+F5 to open the Command Prompt and it should have the output and "press any key to continue."

In C99(ISO/IEC 9899:TC3) which seems absent from this discussion thus far the following steteents are made regarding order of evaluaiton.

[...]the order of evaluation of subexpressions and the order in which side effects take place are both unspecified. (Section 6.5 pp 67)

The order of evaluation of the operands is unspecified. If an attempt is made to modify the result of an assignment operator or to access it after the next sequence point, the behavior[sic] is undefined.(Section 6.5.16 pp 91)

I ran into this when I reduced the number of user-input parameters in userInput from 3 to 1. This changed the variable output type of userInput from an array to a primitive.

Example:

myvar1 = userInput['param1']
myvar2 = userInput['param2']

to:

myvar = userInput

SSLSHopper has some pretty thorough articles about moving between different servers.

http://www.sslshopper.com/how-to-move-or-copy-an-ssl-certificate-from-one-server-to-another.html

Just pick the relevant link at bottom of this page.

Note: they have an online converter which gives them access to your private key. They can probably be trusted but it would be better to use the OPENSSL command (also shown on this site) to keep the private key private on your own machine.

Use \t and enclose the string with double-quotes:

The three constants have similar functions nowadays, but different historical origins, and very occasionally you may be required to use one or the other.

You need to think back to the days of old manual typewriters to get the origins of this. There are two distinct actions needed to start a new line of text:

1. move the typing head back to the left. In practice in a typewriter this is done by moving the roll which carries the paper (the "carriage") all the way back to the right -- the typing head is fixed. This is a carriage return.
2. move the paper up by the width of one line. This is a line feed.

In computers, these two actions are represented by two different characters - carriage return is CR, ASCII character 13, vbCr; line feed is LF, ASCII character 10, vbLf. In the old days of teletypes and line printers, the printer needed to be sent these two characters -- traditionally in the sequence CRLF -- to start a new line, and so the CRLF combination -- vbCrLf -- became a traditional line ending sequence, in some computing environments.

The problem was, of course, that it made just as much sense to only use one character to mark the line ending, and have the terminal or printer perform both the carriage return and line feed actions automatically. And so before you knew it, we had 3 different valid line endings: LF alone (used in Unix and Macintoshes), CR alone (apparently used in older Mac OSes) and the CRLF combination (used in DOS, and hence in Windows). This in turn led to the complications of DOS / Windows programs having the option of opening files in text mode, where any CRLF pair read from the file was converted to a single CR (and vice versa when writing).

So - to cut a (much too) long story short - there are historical reasons for the existence of the three separate line separators, which are now often irrelevant: and perhaps the best course of action in .NET is to use Environment.NewLine which means someone else has decided for you which to use, and future portability issues should be reduced.

This code can also compare floats. It is using awk (it is not pure bash), however this shouldn't be a problem, as awk is a standard POSIX command that is most likely shipped by default with your operating system.

$ awk 'BEGIN {return_code=(-1.2345 == -1.2345) ? 0 : 1; exit} END {exit return_code}'
$ echo $?
0
$ awk 'BEGIN {return_code=(-1.2345 >= -1.2345) ? 0 : 1; exit} END {exit return_code}'
$ echo $?
0
$ awk 'BEGIN {return_code=(-1.2345 < -1.2345) ? 0 : 1; exit} END {exit return_code}'
$ echo $?
1
$ awk 'BEGIN {return_code=(-1.2345 < 2) ? 0 : 1; exit} END {exit return_code}'
$ echo $?
0
$ awk 'BEGIN {return_code=(-1.2345 > 2) ? 0 : 1; exit} END {exit return_code}'
$ echo $?

To make it shorter for use, use this function:

compare_nums()
{
   # Function to compare two numbers (float or integers) by using awk.
   # The function will not print anything, but it will return 0 (if the comparison is true) or 1
   # (if the comparison is false) exit codes, so it can be used directly in shell one liners.
   #############
   ### Usage ###
   ### Note that you have to enclose the comparison operator in quotes.
   #############
   # compare_nums 1 ">" 2 # returns false
   # compare_nums 1.23 "<=" 2 # returns true
   # compare_nums -1.238 "<=" -2 # returns false
   #############################################
   num1=$1
   op=$2
   num2=$3
   E_BADARGS=65

   # Make sure that the provided numbers are actually numbers.
   if ! [[ $num1 =~ ^-?[0-9]+([.][0-9]+)?$ ]]; then >&2 echo "$num1 is not a number"; return $E_BADARGS; fi
   if ! [[ $num2 =~ ^-?[0-9]+([.][0-9]+)?$ ]]; then >&2 echo "$num2 is not a number"; return $E_BADARGS; fi

   # If you want to print the exit code as well (instead of only returning it), uncomment
   # the awk line below and comment the uncommented one which is two lines below.
   #awk 'BEGIN {print return_code=('$num1' '$op' '$num2') ? 0 : 1; exit} END {exit return_code}'
   awk 'BEGIN {return_code=('$num1' '$op' '$num2') ? 0 : 1; exit} END {exit return_code}'
   return_code=$?
   return $return_code
}

$ compare_nums -1.2345 ">=" -1.2345 && echo true || echo false
true
$ compare_nums -1.2345 ">=" 23 && echo true || echo false
false

You should inject a startup script that will close the page after the postback has finished.

ClientScript.RegisterStartupScript(typeof(Page), "closePage", "<script type='text/JavaScript'>window.close();</script>"); 

Technique described in this article by Ian Robertson works for me.

In short quick and dirty example:

Powder's comment may go undetected like I missed it so many times,. So with the hope of making it more visible, I will re-iterate his point.

Sometimes using image = array(img).reshape(a,b,c,d) will reshape alright but from experience, my kernel crashes every time I try to use the new dimension in an operation. The safest to use is

np.expand_dims(img, axis=0)

It works perfect every time. I just can't explain why. This link has a great explanation and examples regarding its usage.

I highly recommend looking into this plugin:

http://github.com/evanplaice/jquery-csv/

I used this for a project handling large CSV files and it handles parsing a CSV into an array quite well. You can use this to call a local file that you specify in your code, also, so you are not dependent on a file upload.

Once you include the plugin above, you can essentially parse the CSV using the following:

$.ajax({
    url: "pathto/filename.csv",
    async: false,
    success: function (csvd) {
        data = $.csv.toArrays(csvd);
    },
    dataType: "text",
    complete: function () {
        // call a function on complete 
    }
});

Everything will then live in the array data for you to manipulate as you need. I can provide further examples for handling the array data if you need.

There are a lot of great examples available on the plugin page to do a variety of things, too.

Same problem with Chrome : I had in my html page the following code :

<body>
  ...
  <script src="http://myserver/lib/load.js"></script>
  ...
</body>

But the load.js was always in status pending when looking in the Network pannel.

I found a workaround using asynchronous load of load.js:

<body>
  ...
  <script>
    setTimeout(function(){
      var head, script;
      head = document.getElementsByTagName("head")[0];
      script = document.createElement("script");
      script.src = "http://myserver/lib/load.js";
      head.appendChild(script);
    }, 1);
  </script>
  ...
</body>

Now its working fine.

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

Try this code:

SELECT * FROM table WHERE column REGEXP '^[A-Za-z0-9]+$'

This makes sure that all characters match.

I just had the same error (with PHP 5.2.6), and all I had to do is enable the MySQL-specific PDO driver:

TL;DR

In your php.ini file, you should have the following line (uncommented):

• extension=php_pdo_mysql.dll on Windows
• extension=php_pdo_mysql.so on Linux/Mac

Longer explanation:

1. open php.ini in a text editor

   • _{e.g. its default path on Windows: C:\Program Files (x86)\PHP\v5.X\php.ini (substitute v5.x with the version you installed) or C:\Windows\php.ini, etc.}
   • _{or on Linux: /etc/php5/apache2/php.ini (e.g. this is the path on Ubuntu) or /etc/php5/cli/php.ini, /etc/php5/cgi/php.ini, etc.}
   • _{or you can get to know where it is like this:}
     • _{php --ini | find /i "Loaded" in Windows command prompt OR}
     • _{php --ini | grep "Loaded" in Linux/Mac terminal}
     • _{using phpinfo(), and looking for the line "Loaded Configuration File"}

2. and remove the semicolon from the beginning of the following line (to uncomment it):

   • ;extension=php_pdo_mysql.dll on Windows
     • OR ;extension=php_pdo_mysql.so on Linux/Mac
   • of course, if this line doesn't exist, you should paste it
   • so as a result the expected line would look like this in php.ini:
     • extension=php_pdo_mysql.dll on Windows
     • OR extension=php_pdo_mysql.so on Linux/Mac

3. You may need to restart your web server.

That solved my problem.

. ~/.bash_profile

Just make sure you don't have any dependencies on the current state in there.

You could us the 'net use' command:

var p = System.Diagnostics.Process.Start("net.exe", "use K: \\\\Server\\path");
var isCompleted = p.WaitForExit(5000);

If that does not work in a service, try the Winapi and PInvoke WNetAddConnection2

Edit: Obviously I misunderstood you - you can not change the sourcecode of the service, right? In that case I would follow the suggestion by mdb, but with a little twist: Create your own service (lets call it mapping service) that maps the drive and add this mapping service to the dependencies for the first (the actual working) service. That way the working service will not start before the mapping service has started (and mapped the drive).

This issue arises when your 64 bit os tries to install the Android SDK which in turns tries to install some 32 bit binaries and thus is the issue of compatibility.

Open an additional terminal and type

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6 

would help to install all the required binaries. After this, start the afresh the Android SDK installation process.

This solution worked for me:

Go to SQL Server Management Studio, Right click on the failing step and select Properties -> Logging -> Remove the Log Provider, and then re-add it

An object can't be null - the value of an expression can be null. It's worth making the difference clear in your mind. The value of s isn't an object - it's a reference, which is either null or refers to an object.

And yes, you should just use

if (s == null)

Note that this will still use the overloaded == operator defined in string, but that will do the right thing.

This example is use reduce(), but slow it:

def makepnl(pnl, n):
    for p in pnl:
        if n % p == 0:
            return pnl
    pnl.append(n)
    return pnl

def isprime(n):
    return True if n == reduce(makepnl, range(3, n + 1, 2), [2])[-1] else False

for i in range(20):
    print i, isprime(i)

It use Sieve Of Atkin, faster than above:

def atkin(limit):
    if limit > 2:
        yield 2
    if limit > 3:
        yield 3

    import math
    is_prime = [False] * (limit + 1)

    for x in range(1,int(math.sqrt(limit))+1):
        for y in range(1,int(math.sqrt(limit))+1):
            n = 4*x**2 + y**2

            if n<=limit and (n%12==1 or n%12==5):
                # print "1st if"                                                                                                                    
                is_prime[n] = not is_prime[n]
            n = 3*x**2+y**2
            if n<= limit and n%12==7:
                # print "Second if"                                                                                                                 
                is_prime[n] = not is_prime[n]
            n = 3*x**2 - y**2
            if x>y and n<=limit and n%12==11:
                # print "third if"                                                                                                                  
                is_prime[n] = not is_prime[n]

    for n in range(5,int(math.sqrt(limit))):
        if is_prime[n]:
            for k in range(n**2,limit+1,n**2):
                is_prime[k] = False

    for n in range(5,limit):
        if is_prime[n]: yield n

def isprime(n):
    r = list(atkin(n+1))
    if not r: return False
    return True if n == r[-1] else False

for i in range(20):
    print i, isprime(i)

The @jfriend00's answer helps me to understand the technique to animate only remove class (not add).

A "base" class should have transition property (like transition: 2s linear all;). This enables animations when any other class is added or removed on this element. But to disable animation when other class is added (and only animate class removing) we need to add transition: none; to the second class.

Example

CSS:

.issue {
  background-color: lightblue;
  transition: 2s linear all;
}

.recently-updated {
  background-color: yellow;
  transition: none;
}

HTML:

<div class="issue" onclick="addClass()">click me</div>

JS (only needed to add class):

var timeout = null;

function addClass() {
  $('.issue').addClass('recently-updated');
  if (timeout) {
    clearTimeout(timeout);
    timeout = null;
  }
  timeout = setTimeout(function () {
    $('.issue').removeClass('recently-updated');
  }, 1000);
}

plunker of this example.

With this code only removing of recently-updated class will be animated.

Try this

#/bin/bash

read -p "Enter a word: " word
echo "You entered $word"

on the form2.buttonclick put

this.close();

form1 should have object of form2.

you need to subscribe Closing event of form2.

and in closing method put

this.close();

In C++20 you'll be able to use std::format to do this:

std::cout << std::format("a is {:x}; b is {:x}\n", a, b);

Output:

a is 0; b is ff

In the meantime you can use the {fmt} library, std::format is based on. {fmt} also provides the print function that makes this even easier and more efficient (godbolt):

fmt::print("a is {:x}; b is {:x}\n", a, b);

Disclaimer: I'm the author of {fmt} and C++20 std::format.

Remember that HTML and XML are two distinct concepts in the tree of markup languages. You can't exactly replace HTML with XML . XML can be viewed as a generalized form of HTML, but even that is imprecise. You mainly use HTML to display data, and XML to carry(or store) the data.

I came across an "inverted" issue — I was getting good results with categorical_crossentropy (with 2 classes) and poor with binary_crossentropy. It seems that problem was with wrong activation function. The correct settings were:

• for binary_crossentropy: sigmoid activation, scalar target
• for categorical_crossentropy: softmax activation, one-hot encoded target

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

As martijn-courteaux said, create a custom component it's the better option. In C# exists a component called PictureBox and I tried to create this component for Java, here is the code:

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JComponent;

public class JPictureBox extends JComponent {

    private Icon icon = null;
    private final Dimension dimension = new Dimension(100, 100);
    private Image image = null;
    private ImageIcon ii = null;
    private SizeMode sizeMode = SizeMode.STRETCH;
    private int newHeight, newWidth, originalHeight, originalWidth;

    public JPictureBox() {
        JPictureBox.this.setPreferredSize(dimension);
        JPictureBox.this.setOpaque(false);
        JPictureBox.this.setSizeMode(SizeMode.STRETCH);
    }

    @Override
    public void paintComponent(Graphics g) {
        if (ii != null) {
            switch (getSizeMode()) {
                case NORMAL:
                    g.drawImage(image, 0, 0, ii.getIconWidth(), ii.getIconHeight(), null);
                    break;
                case ZOOM:
                    aspectRatio();
                    g.drawImage(image, 0, 0, newWidth, newHeight, null);
                    break;
                case STRETCH:
                    g.drawImage(image, 0, 0, this.getWidth(), this.getHeight(), null);
                    break;
                case CENTER:
                    g.drawImage(image, (int) (this.getWidth() / 2) - (int) (ii.getIconWidth() / 2), (int) (this.getHeight() / 2) - (int) (ii.getIconHeight() / 2), ii.getIconWidth(), ii.getIconHeight(), null);
                    break;
                default:
                    g.drawImage(image, 0, 0, this.getWidth(), this.getHeight(), null);
            }
        }
    }

    public Icon getIcon() {
        return icon;
    }

    public void setIcon(Icon icon) {
        this.icon = icon;
        ii = (ImageIcon) icon;
        image = ii.getImage();
        originalHeight = ii.getIconHeight();
        originalWidth = ii.getIconWidth();
    }

    public SizeMode getSizeMode() {
        return sizeMode;
    }

    public void setSizeMode(SizeMode sizeMode) {
        this.sizeMode = sizeMode;
    }

    public enum SizeMode {
        NORMAL,
        STRETCH,
        CENTER,
        ZOOM
    }

    private void aspectRatio() {
        if (ii != null) {
            newHeight = this.getHeight();
            newWidth = (originalWidth * newHeight) / originalHeight;
        }
    }

}

If you want to add an image, choose the JPictureBox, after that go to Properties and find "icon" property and select an image. If you want to change the sizeMode property then choose the JPictureBox, after that go to Properties and find "sizeMode" property, you can choose some values:

• NORMAL value, the image is positioned in the upper-left corner of the JPictureBox.
• STRETCH value causes the image to stretch or shrink to fit the JPictureBox.
• ZOOM value causes the image to be stretched or shrunk to fit the JPictureBox; however, the aspect ratio in the original is maintained.
• CENTER value causes the image to be centered in the client area.

Also you can see the code on Gitlab or Github.

For hiding a widget you can use function pack_forget() and to again show it you can use pack() function and implement them both in separate functions.

from Tkinter import *
root = Tk()
label=Label(root,text="I was Hidden")
def labelactive():
    label.pack()
def labeldeactive():
    label.pack_forget()
Button(root,text="Show",command=labelactive).pack()
Button(root,text="Hide",command=labeldeactive).pack()
root.mainloop()

The problem is the import of ProjectsListComponent in your ProjectsModule. You should not import that, but add it to the export array, if you want to use it outside of your ProjectsModule.

Other issues are your project routes. You should add these to an exportable variable, otherwise it's not AOT compatible. And you should -never- import the BrowserModule anywhere else but in your AppModule. Use the CommonModule to get access to the *ngIf, *ngFor...etc directives:

@NgModule({
  declarations: [
     ProjectsListComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(ProjectRoutes)
  ],
  exports: [
     ProjectsListComponent
  ]
})

export class ProjectsModule {}

project.routes.ts

export const ProjectRoutes: Routes = [
      { path: 'projects', component: ProjectsListComponent }
]

I had this same error. I had everything written in correctly, including the Listing 10.13 from the tutorial.

Rails.application.configure do
.
.
.
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delevery_method :test
host = 'example.com'
config.action_mailer.default_url_options = { host: host }
.
.
.
end

obviously with "example.com" replaced with my server url.

What I had glossed over in the tutorial was this line:

After restarting the development server to activate the configuration...

So the answer for me was to turn the server off and back on again.

If the order is important, you should make the order yourself.

@Test public void test1() { ... }
@Test public void test2() { test1(); ... }

In particular, you should list some or all possible order permutations to test, if necessary.

For example,

void test1(); 
void test2(); 
void test3(); 


@Test
public void testOrder1() { test1(); test3(); }

@Test(expected = Exception.class)
public void testOrder2() { test2(); test3(); test1(); }

@Test(expected = NullPointerException.class)
public void testOrder3() { test3(); test1(); test2(); }

Or, a full test of all permutations:

@Test
public void testAllOrders() {
    for (Object[] sample: permute(1, 2, 3)) {
        for (Object index: sample) {
            switch (((Integer) index).intValue()) {
                case 1: test1(); break; 
                case 2: test2(); break; 
                case 3: test3(); break; 
            }
        }
    }
}

Here, permute() is a simple function which iterates all possible permuations into a Collection of array.

Got this error when I was setting up Posgtres with Django, I'm using Back Track and it comes with Postgres installed. I assume the settings are the issue. I fixed it by removing it completely then reinstalling like so.

sudo apt-get remove postgresql
sudo apt-get purge postgresql

Now run:

apt-get --purge remove postgresql\*

to remove everything PostgreSQL from your system. Just purging the postgres package isn't enough since it's just an empty meta-package.

Once all PostgreSQL packages have been removed, run:

rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres

You should now be able to:

apt-get install postgresql

I had the same problem, but I didnt find export command in line 70 in gradle file for the latest version 2.13, but I understand a silly mistake there, that is following,

If you don't find line 70 with export command in gradle file in your gradle folder/bin/ , then check your ~/.bashrc, if you find export JAVA_HOME==/usr/lib/jvm/java-7-openjdk-amd64/bin/java, then remove /bin/java from this line, like JAVA_HOME==/usr/lib/jvm/java-7-openjdk-amd64, and it in path>>> instead of this export PATH=$PATH:$HOME/bin:JAVA_HOME/, it will be export PATH=$PATH:$HOME/bin:JAVA_HOME/bin/java. Then run source ~/.bashrc.

The reason is, if you check your gradle file, you will find in line 70 (if there's no export command) or in line 75,

JAVACMD="$JAVA_HOME/bin/java"
    fi
    if [ ! -x "$JAVACMD" ] ; then
        die "ERROR: JAVA_HOME is set to an invalid directory: $JAVA_HOME

That means /bin/java is already there, so it needs to be substracted from JAVA_HOME path.

That happened in my case.

Set the href attribute with

$(selector).attr('href', 'url_goes_here');

and read it using

$(selector).attr('href');

Where "selector" is any valid jQuery selector for your <a> element (".myClass" or "#myId" to name the most simple ones).

Hope this helps !

I have just encountered a bug while using most of the solutions above that suggest adding a fixed number.

S4 is has a high dpi which resulted in the navigation bar's height being 100px thus my app thinking that the keyboard is open all the time.

So with all the new high res phones being released i believe using a hard coded value is not a good idea for long term.

A better approach that i found after some testing on various screens and devices was to use percentage. Get the difference between decorView and ur app content and afterwards check what is the percentage of that difference. From the stats that i got, most nav bar(regardless of the size, resolution etc..) will take between 3% to 5% of the screen. Where as if the keyboard is open it was taking between 47% to 55% of the screen.

As a conclusion my solution was to check if the diff is more than 10% then i assume its a keyboard open.

I created one more list by sorting Jaspers list by device RAM (I made my own tests with Split's tool and fixed some results - check my comments in Jaspers thread).

device RAM: percent range to crash

• 256MB: 49% - 51%
• 512MB: 53% - 63%
• 1024MB: 57% - 68%
• 2048MB: 68% - 69%
• 3072MB: 63% - 66%
• 4096MB: 77%
• 6144MB: 81%

Special cases:

• iPhone X (3072MB): 50%
• iPhone XS/XS Max (4096MB): 55%
• iPhone XR (3072MB): 63%
• iPhone 11/11 Pro Max (4096MB): 54% - 55%

Device RAM can be read easily:

[NSProcessInfo processInfo].physicalMemory

From my experience it is safe to use 45% for 1GB devices, 50% for 2/3GB devices and 55% for 4GB devices. Percent for macOS can be a bit bigger.

You are most likely not using the correct credentials for the MySQL server. You also need to ensure the user you are connecting as has the correct privileges to view databases/tables, and that you can connect from your current location in network topographic terms (localhost).

The version I'm using I think is the good one, since is the exact same as the Android Developer Docs, except for the name of the string, they used "view" and I used "webview", for the rest is the same

No, it is not.

The one that is new to the N Developer Preview has this method signature:

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)

The one that is supported by all Android versions, including N, has this method signature:

public boolean shouldOverrideUrlLoading(WebView view, String url)

So why should I do to make it work on all versions?

Override the deprecated one, the one that takes a String as the second parameter.

The below code will help you to merge two JSON object which has nested objects.

function mergeJSON(source1,source2){
    /*
     * Properties from the Souce1 object will be copied to Source2 Object.
     * Note: This method will return a new merged object, Source1 and Source2 original values will not be replaced.
     * */
    var mergedJSON = Object.create(source2);// Copying Source2 to a new Object

    for (var attrname in source1) {
        if(mergedJSON.hasOwnProperty(attrname)) {
          if ( source1[attrname]!=null && source1[attrname].constructor==Object ) {
              /*
               * Recursive call if the property is an object,
               * Iterate the object and set all properties of the inner object.
              */
              mergedJSON[attrname] = zrd3.utils.mergeJSON(source1[attrname], mergedJSON[attrname]);
          } 

        } else {//else copy the property from source1
            mergedJSON[attrname] = source1[attrname];

        }
      }

      return mergedJSON;
}

For those of you that do need a non jQuery answer you can simple add the following:

xmlhttp.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'));

A very simple example can be sen here:

xmlhttp.open("POST","example.html",true);
xmlhttp.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'));
xmlhttp.send();

This is the closest I could get without adding any custom CSS (this I'd already figured as of the time of asking the question; guess I've to stick with this):

And the markup in use:

<form class="navbar-form navbar-left" role="search">
    <div class="form-group">
        <input type="text" class="form-control" placeholder="Search">
    </div>
    <button type="submit" class="btn btn-default">
        <span class="glyphicon glyphicon-search"></span>
    </button>
</form>

PS: Of course, that can be fixed by adding a negative margin-left (-4px) on the button, and removing the border-radius on the sides input and button meet. But the whole point of this question is to get it to work without any custom CSS.

Really fast comparison, to get count of differences. Using specific column name.

colname = "CreatedDate" # specify column name
index <- match(colname, names(source_df)) # get index name for column name
sel <- source_df[, index] == target_df[, index] # get differences, gives you dataframe with TRUE and FALSE values
table(sel)["FALSE"] # count of differences
table(sel)["TRUE"] # count of matches

For complete dataframe, do not provide column or index name

sel <- source_df[, ] == target_df[, ] # gives you dataframe with TRUE and FALSE values
table(sel)["FALSE"] # count of differences
table(sel)["TRUE"] # count of matches

You can simply write

new ArrayList<MyEnum>(Arrays.asList(MyEnum.values()));

main() {
    double a;
    a=3669.0;
    int b;
    b=a;
    printf("b is %d",b);
  
}

output is :b is 3669

when you write b=a; then its automatically converted in int

var myArray = [

    {field: 'cStatus', operator: 'eq', value: cStatus}, 
    {field: 'money', operator: 'eq', value: money}
];
console.log(myArray.length); //3
myArray = $.grep(myArray, function(element, index){return element.field == "money"}, true);
console.log(myArray.length); //2

Element is an object in the array. 3rd parameter true means will return an array of elements which fails your function logic, false means will return an array of elements which fails your function logic.

Slight change to make it work on my region, Europe (. as thousands separator, comma as decimal separator):

[<1000000]#.##0,00" KB";[<1000000000]#.##0,00.." MB";#.##0,00..." GB"

Still same issue on data conversion (1000 != 1024) but it does the job for me.

Just add this property inside your toolbar and its done

app:layout_scrollFlags="scroll|enterAlways"

Isn't is awesome

I randomly recieved this error after deleting a few directories each containing some files. I deleted the directories through Netbeans and realised that it didn't actually delete them. It seemed to just delete everything inside the directories and removed the reference to the directory within Netbeans. They did still exist on the filesystem though. Make sure they're deleted from the filesystem and try the commit again.

There are several ways you can achieve this. One would be something like:

for filepath in /path/to/dir/*
do
    filename=$(basename $filepath)

    ... whatever you want to do with the file here
done

yes datediff is implemented; see: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF

By the way I found this by Google-searching "hive datediff", it was the first result ;)

make sure your css reads:

margin: 0 auto;

Even though you're saying you have the left and right set to auto, you may be placing an error. Of course we wouldn't know though because you did not show us any code.

For example for 3.6 version type py -3.6. If you have also 32bit and 64bit versions, you can just type py -3.6-64 or py -3.6-32.

android:minSdkVersion

An integer designating the minimum API Level required for the application to run. The Android system will prevent the user from installing the application if the system's API Level is lower than the value specified in this attribute. You should always declare this attribute.

android:targetSdkVersion

An integer designating the API Level that the application is targetting.

With this attribute set, the application says that it is able to run on older versions (down to minSdkVersion), but was explicitly tested to work with the version specified here. Specifying this target version allows the platform to disable compatibility settings that are not required for the target version (which may otherwise be turned on in order to maintain forward-compatibility) or enable newer features that are not available to older applications. This does not mean that you can program different features for different versions of the platform—it simply informs the platform that you have tested against the target version and the platform should not perform any extra work to maintain forward-compatibility with the target version.

cPickle comes with the standard library… in python 2.x. You are on python 3.x, so if you want cPickle, you can do this:

>>> import _pickle as cPickle

However, in 3.x, it's easier just to use pickle.

No need to install anything. If something requires cPickle in python 3.x, then that's probably a bug.

Please try the below code:

<script> 
 const games = {
  "Fifa": "232",
  "Minecraft": "476",
  "Call of Duty": "182"
 };

Object.keys(games).forEach((item, index, array) => {
  var msg = item+' '+games[item];
  console.log(msg);
});

It is important to test what you are expecting entity framework to do (i.e. validate your expectations). One way to do this that I have used successfully, is using moq as shown in this example (to long to copy into this answer):

https://docs.microsoft.com/en-us/ef/ef6/fundamentals/testing/mocking

However be careful... A SQL context is not guaranteed to return things in a specific order unless you have an appropriate "OrderBy" in your linq query, so its possible to write things that pass when you test using an in-memory list (linq-to-entities) but fail in your uat / live environment when (linq-to-sql) gets used.

For windows:

import pip

help(pip) 

shows the version at the end of the help file.

This guide was helpful for me http://wiki.eclipse.org/EGit/User_Guide#Resolving_a_merge_conflict.

UPDATED Just a note on that about my procedure, this is how I proceed:

1. Commit My change
2. Fetch (Syncrhonize workspace)
3. Pull
4. Manage Conflicts with Merge Tool (Team->Merge Tool) and Save
5. Add each file to stage (Team -> Add to index)
6. Now the Commit Message in the Stage window is prefilled with "Merged XXX". You can leave as it is or change the commit message
7. Commit and Push

It is dangerous in some cases but it is very usefull to avoid to use external tool like Git Extension or Source Tree

Edit 2018-05-28 I have changed the example to use Java 8's Time API:

LocalDate d1 = LocalDate.parse("2018-05-26", DateTimeFormatter.ISO_LOCAL_DATE);
LocalDate d2 = LocalDate.parse("2018-05-28", DateTimeFormatter.ISO_LOCAL_DATE);
Duration diff = Duration.between(d1.atStartOfDay(), d2.atStartOfDay());
long diffDays = diff.toDays();

Unit test is usually done for a single functionality implemented in Software module. The scope of testing is entirely within this SW module. Unit test never fulfils the final functional requirements. It comes under whitebox testing methodology..

Whereas Integration test is done to ensure the different SW module implementations. Testing is usually carried out after module level integration is done in SW development.. This test will cover the functional requirements but not enough to ensure system validation.

This should give what you want:

FLOOR(RAND() * 401) + 100

Generically, FLOOR(RAND() * (<max> - <min> + 1)) + <min> generates a number between <min> and <max> inclusive.

Update

This full statement should work:

SELECT name, address, FLOOR(RAND() * 401) + 100 AS `random_number` 
FROM users

This is what I achieved, but had to set width, and it cannot be percentual.

If you are an iPhone Developer don't just add your picture (by right clicking then add file...like we do in iPhone). You have to copy and paste the picture in your drawable folder.

To list only the containers SHA1:

docker ps -aq --no-trunc

That way, you can use the list of all containers for other commands (which accept multiple container ids as parameters).

For example, to list only the name of all containers (since docker ps list only their names with other information):

docker inspect --format='{{.Name}}' $(sudo docker ps -aq --no-trunc)

Math.round also returns an integer value, so you don't need to typecast.

int b = Math.round(float a);

The C# struct is a lightweight alternative to a class. It can do almost the same as a class, but it's less "expensive" to use a struct rather than a class. The reason for this is a bit technical, but to sum up, new instances of a class is placed on the heap, where newly instantiated structs are placed on the stack. Furthermore, you are not dealing with references to structs, like with classes, but instead you are working directly with the struct instance. This also means that when you pass a struct to a function, it is by value, instead of as a reference. There is more about this in the chapter about function parameters.

So, you should use structs when you wish to represent more simple data structures, and especially if you know that you will be instantiating lots of them. There are lots of examples in the .NET framework, where Microsoft has used structs instead of classes, for instance the Point, Rectangle and Color struct.

The C way:

char buf[100];
strcpy(buf, one);
strcat(buf, two);

The C++ way:

std::string buf(one);
buf.append(two);

The compile-time way:

#define one "hello "
#define two "world"
#define concat(first, second) first second

const char* buf = concat(one, two);

10 * * * Sun

Position 1 for minutes, allowed values are 1-60
position 2 for hours, allowed values are 1-24
position 3 for day of month ,allowed values are 1-31
position 4 for month ,allowed values are 1-12 
position 5 for day of week ,allowed values are 1-7 or and the day starts at Monday. 

If you're using AD you can use serverless binding to locate a domain controller for the default domain, then use LDAP://rootDSE to get information about the directory server, as described in the linked article.

The EOF pattern needs a prime read to 'bootstrap' the EOF checking process. Consider the empty file will not initially have its EOF set until the first read. The prime read will catch the EOF in this instance and properly skip the loop completely.

What you need to remember here is that you don't get the EOF until the first attempt to read past the available data of the file. Reading the exact amount of data will not flag the EOF.

I should point out if the file was empty your given code would have printed since the EOF will have prevented a value from being set to x on entry into the loop.

• 0

So add a prime read and move the loop's read to the end:

int x;

iFile >> x; // prime read here
while (!iFile.eof()) {
    cerr << x << endl;
    iFile >> x;
}

I got this error on my mac too. I use npm run dev to run my Nodejs app in Windows and it works fine. But I got this error on my mac - error given was: Error: bind EACCES null:80.

One way to solve this is to run it with root access. You may use sudo npm run dev and will need you to put in your password.

It is generally preferable to serve your application on a non privileged port, such as 3000, which will work without root permissions.

reference: Node.js EACCES error when listening on http 80 port (permission denied)

I would like to add that you can extend the compatibility of :scope by just assigning a temporary attribute to the current node.

let node = [...];
let result;

node.setAttribute("foo", "");
result = window.document.querySelectorAll("[foo] > .bar");
// And, of course, you can also use other combinators.
result = window.document.querySelectorAll("[foo] + .bar");
result = window.document.querySelectorAll("[foo] ~ .bar");
node.removeAttribute("foo");

Just call array.ToObject<List<SelectableEnumItem>>() method. It will return what you need.

Documentation: Convert JSON to a Type

What do you want to search near that known place?

For example if you want to search a restaurant near a known place you can use the parameters "q=" and "near=" and construct this URL: maps.google.com/?q=restaurant&near=47.154719,27.60551

For a list of complete parameters you can see this: https://web.archive.org/web/20070708030513/http://mapki.com/wiki/Google_Map_Parameters

Depending on what is the format you want your information in you can add at the end of the url the parameter output like this: maps.google.com/?q=restaurant&near=47.154719,27.60551&output=kml

For more types of output format you can read chapter 2 of this: http://csie-tw.blogspot.de/2009/06/android-driving-direction-route-path.html

Try this (apply to a class you image is in (not img itself), e.g.

.myimage {
  background: transparent url("yourimage.png") no-repeat top center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: 100%;
  height: 500px;
}

grep's -A 1 option will give you one line after; -B 1 will give you one line before; and -C 1 combines both to give you one line both before and after, -1 does the same.

String.IsNullOrEmpty(string value) returns true if the string is null or empty. For reference an empty string is represented by "" (two double quote characters)

String.IsNullOrWhitespace(string value) returns true if the string is null, empty, or contains only whitespace characters such as a space or tab.

To see what characters count as whitespace consult this link: http://msdn.microsoft.com/en-us/library/t809ektx.aspx

You might have them turned off in your gmail settings, heres the link to change them https://support.google.com/mail/answer/145919?hl=en

Also gmail may be blocking the images thinking they are suspicious.

from the link above.

How Gmail makes images safe

Some senders try to use externally linked images in harmful ways, but Gmail takes action to ensure that images are loaded safely. Gmail serves all images through Google’s image proxy servers and transcodes them before delivery to protect you in the following ways:

Senders can’t use image loading to get information like your IP address or location. Senders can’t set or read cookies in your browser. Gmail checks your images for known viruses or malware. In some cases, senders may be able to know whether an individual has opened a message with unique image links. As always, Gmail scans every message for suspicious content and if Gmail considers a sender or message potentially suspicious, images won’t be displayed and you’ll be asked whether you want to see the images.

Now Android Studio 3.3 and later version provide an inbuilt feature to change an Alpha value of the color,

Just click on a color in Android studio editor and provide Alpha value in percentage.

For more information see below image

HTML file:

<input [ngModel]="filterValue"
       (ngModelChange)="filterValue = $event ; search($event)"
        placeholder="Search..."/>

TS file:

timer = null;
time = 250;
  search(searchStr : string) : void {
    clearTimeout(this.timer);
    this.timer = setTimeout(()=>{
      console.log(searchStr);
    }, time)
  }

Views also break down very complex configuration and tables into managable chunks that are easily queried against. In our database, our entire table managment system is broken down into views from one large table.

There could be a lot of reason when you get this kind of error:

1. Check whether you have selected a provisioning profile which includes the valid Code Signing Identity and a valid Bundle Identifier in Settings. (Goto Build Settings->Signing->Provisioning Profile).

2. Open Keychain Access and click on lock icon at top left, so it will lock the login keychain and then again click to unlock.

3. Goto File->Project Settings->Derived Data and delete your project build folder. After that clean and build your app.

Since you are using JSON.NET, personally I would go with serialization so that you can have Intellisense support for your object. You'll need a class that represents your JSON structure. You can build this by hand, or you can use something like json2csharp to generate it for you:

e.g.

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public class RootObject
{
    public List<Person> People { get; set; }
}

Then, you can simply call JsonConvert's methods to deserialize the JSON into an object:

RootObject instance = JsonConvert.Deserialize<RootObject>(json);

Then you have Intellisense:

var firstName = instance.People[0].FirstName;
var lastName = instance.People[0].LastName;

Perhaps you installed the latest Android Studio 2.3.1, it changed command android list targets to avdmanager list targets, so there is how to fix it:

add path <android-sdk>/tools/bin to PATH, this is for MacOX.

export PATH="$PATH:/Users/<username>/Library/Android/sdk/tools/bin"

change your cordova project code <your-cordova-project>/platforms/android/cordova/lib/android_sdk.js.

change

module.exports.list_targets_with_android = function() {
    return superspawn.spawn('android', ['list', 'targets'])

to

module.exports.list_targets_with_android = function() {
    return superspawn.spawn('avdmanager', ['list', 'targets'])

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

Use this

$ dig +short stackoverflow.com

69.59.196.211

or this

$ host stackoverflow.com

stackoverflow.com has address 69.59.196.211
stackoverflow.com mail is handled by 30 alt2.aspmx.l.google.com.
stackoverflow.com mail is handled by 40 aspmx2.googlemail.com.
stackoverflow.com mail is handled by 50 aspmx3.googlemail.com.
stackoverflow.com mail is handled by 10 aspmx.l.google.com.
stackoverflow.com mail is handled by 20 alt1.aspmx.l.google.com.

If this problem persists, you may want to check all path values in the PATH variable (under Control Panel\System and Security\System\Advanced System Settings). It might be that some other path is invalid or contains an illegal character.

Today, I had the same problem and found a double quote in a different path value in the PATH variable. All paths after that (including a fresly installed conda) were not usable. Removing the double quote solved the problem.

Adding ... android:usesCleartextTraffic="true" ... to your manifest file may appear to fix the problem but it opens a threat to data integrity.

For security reasons I used manifest placeholders with android:usesCleartextTraffic inside the manifest file (like in Option 3 of the accepted answer i.e @Hrishikesh Kadam's response) to only allow cleartext on debug environment.

Inside my build.gradle(:app) file, I added a manifest placeholder like this:

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }

        debug {
            manifestPlaceholders.cleartextTrafficPermitted ="true"
        }
    }

Note the placeholder name cleartextTrafficPermitted at this line above

            manifestPlaceholders.cleartextTrafficPermitted ="true"

Then in my Android Manifest, I used the same placeholder ...

AndroidManifest.xml -

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:usesCleartextTraffic="${cleartextTrafficPermitted}"
        ...>
        ...
    </application>
</manifest>

With that, cleartext traffic is only permitted under the debug environment.

Alternatively, with MTCNN and OpenCV(other dependencies including TensorFlow also required), you can:

1 Perform face detection(Input an image, output all boxes of detected faces):

from mtcnn.mtcnn import MTCNN
import cv2

face_detector = MTCNN()

img = cv2.imread("Anthony_Hopkins_0001.jpg")
detect_boxes = face_detector.detect_faces(img)
print(detect_boxes)

[{'box': [73, 69, 98, 123], 'confidence': 0.9996458292007446, 'keypoints': {'left_eye': (102, 116), 'right_eye': (150, 114), 'nose': (129, 142), 'mouth_left': (112, 168), 'mouth_right': (146, 167)}}]

2 save all detected faces to separate files:

for i in range(len(detect_boxes)):
    box = detect_boxes[i]["box"]
    face_img = img[box[1]:(box[1] + box[3]), box[0]:(box[0] + box[2])]
    cv2.imwrite("face-{:03d}.jpg".format(i+1), face_img)

3 or Draw rectangles of all detected faces:

for box in detect_boxes:
    box = box["box"]
    pt1 = (box[0], box[1]) # top left
    pt2 = (box[0] + box[2], box[1] + box[3]) # bottom right
    cv2.rectangle(img, pt1, pt2, (0,255,0), 2)
cv2.imwrite("detected-boxes.jpg", img)

The answers mentioned here is quite elegant https://stackoverflow.com/a/6095776/1869562 but upon testing, I realize it only returns the last name. What if you want to return the entire record itself ? Do this (For Mysql)

SELECT *
FROM `beneficiary`
WHERE `lastname`
IN (

  SELECT `lastname`
  FROM `beneficiary`
  GROUP BY `lastname`
  HAVING COUNT( `lastname` ) >1
)

Like This:

[1,2,3,4].join('; ')

Google has a serious liking for goats and goat based Easter eggs. There has even been previous Stack Overflow posts about it.

As has been mentioned in previous posts, it also exists within the Chrome task manager (it first appeared in the wild in 2009):

<message name="IDS_TASK_MANAGER_GOATS_TELEPORTED_COLUMN" desc="The goats teleported column">
    Goats Teleported
</message>

And then in Windows, Linux and Mac versions of Chrome early 2010). The number of "Goats Teleported" is in fact random:

 int TaskManagerModel::GetGoatsTeleported(int index) const {
     int seed = goat_salt_ * (index + 1);
     return (seed >> 16) & 255;
 }

Other Google references to goats include:

• Mowing with goats
• The goats are baaaahk

The earliest correlation of goats and Google belongs in the original "Mowing with goats" blog post, as far as I can tell.

We can safely assume that it's merely an Easter egg and has no real-world use, except for returning false.

Another way to make it work:

echo "mysql-server-5.5 mysql-server/root_password password root" | debconf-set-selections
echo "mysql-server-5.5 mysql-server/root_password_again password root" | debconf-set-selections
apt-get -y install mysql-server-5.5

Note that this simply sets the password to "root". I could not get it to set a blank password using simple quotes '', but this solution was sufficient for me.

Based on a solution here.

If the columns in df1 is a subset of those in df2 (by column names):

df3 <- rbind(df1, df2[, names(df1)])

Since the other answers explained how to do it without actually explaining why it works:

When the switch executes, it finds the first matching case statement and then executes each line of code after the switch until it hits either a break statement or the end of the switch (or a return statement to leave the entire containing function). When you deliberately omit the break so that code under the next case gets executed too that's called a fall-through. So for the OP's requirement:

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

   case "details-page":
      alert("goodbye");
      break;
} 

Forgetting to include break statements is a fairly common coding mistake and is the first thing you should look for if your switch isn't working the way you expected. For that reason some people like to put a comment in to say "fall through" to make it clear when break statements have been omitted on purpose. I do that in the following example since it is a bit more complicated and shows how some cases can include code to execute before they fall-through:

switch (someVar) {
   case 1:
      someFunction();
      alert("It was 1");
      // fall through
   case 2:
      alert("The 2 case");
      // fall through
   case 3:
      // fall through
   case 4:
      // fall through
   case 5:
      alert("The 5 case");
      // fall through
   case 6:
      alert("The 6 case");
      break;

   case 7:
      alert("Something else");
      break;

   case 8:
      // fall through
   default:
      alert("The end");
      break;
}

You can also (optionally) include a default case, which will be executed if none of the other cases match - if you don't include a default and no cases match then nothing happens. You can (optionally) fall through to the default case.

So in my second example if someVar is 1 it would call someFunction() and then you would see four alerts as it falls through multiple cases some of which have alerts under them. Is someVar is 3, 4 or 5 you'd see two alerts. If someVar is 7 you'd see "Something else" and if it is 8 or any other value you'd see "The end".

In Jenkins ver. 1.635, it is impossible to show a native environment variable like this:

$BUILD_NUMBER or ${BUILD_NUMBER}

In this case, you have to set it in an other variable.

set BUILDNO = $BUILD_NUMBER
$BUILDNO

Best option I found was http://html2canvas.hertzen.com/
http://jsfiddle.net/nurbsurf/1235emen/

html2canvas(document.body, {  
  onrendered: function(canvas) {
    $("#page").hide();
    document.body.appendChild(canvas);
    window.print();
    $('canvas').remove();
    $("#page").show();
  }
});

Generally we use word count example in hadoop. I will take the same use case and will use map and flatMap and we will see the difference how it is processing the data.

Below is the sample data file.

hadoop is fast
hive is sql on hdfs
spark is superfast
spark is awesome

The above file will be parsed using map and flatMap.

Using map

>>> wc = data.map(lambda line:line.split(" "));
>>> wc.collect()
[u'hadoop is fast', u'hive is sql on hdfs', u'spark is superfast', u'spark is awesome']

Input has 4 lines and output size is 4 as well, i.e., N elements ==> N elements.

Using flatMap

>>> fm = data.flatMap(lambda line:line.split(" "));
>>> fm.collect()
[u'hadoop', u'is', u'fast', u'hive', u'is', u'sql', u'on', u'hdfs', u'spark', u'is', u'superfast', u'spark', u'is', u'awesome']

The output is different from map.

Let's assign 1 as value for each key to get the word count.

• fm: RDD created by using flatMap
• wc: RDD created using map

>>> fm.map(lambda word : (word,1)).collect()
[(u'hadoop', 1), (u'is', 1), (u'fast', 1), (u'hive', 1), (u'is', 1), (u'sql', 1), (u'on', 1), (u'hdfs', 1), (u'spark', 1), (u'is', 1), (u'superfast', 1), (u'spark', 1), (u'is', 1), (u'awesome', 1)]

Whereas flatMap on RDD wc will give the below undesired output:

>>> wc.flatMap(lambda word : (word,1)).collect()
[[u'hadoop', u'is', u'fast'], 1, [u'hive', u'is', u'sql', u'on', u'hdfs'], 1, [u'spark', u'is', u'superfast'], 1, [u'spark', u'is', u'awesome'], 1]

You can't get the word count if map is used instead of flatMap.

As per the definition, difference between map and flatMap is:

map: It returns a new RDD by applying given function to each element of the RDD. Function in map returns only one item.

flatMap: Similar to map, it returns a new RDD by applying a function to each element of the RDD, but output is flattened.

You could write a jQuery function which allowed you to add hidden fields to a form:

// This must be applied to a form (or an object inside a form).
jQuery.fn.addHidden = function (name, value) {
    return this.each(function () {
        var input = $("<input>").attr("type", "hidden").attr("name", name).val(value);
        $(this).append($(input));
    });
};

And then add the hidden field before you submit:

var frm = $("#form").addHidden('SaveAndReturn', 'Save and Return')
                    .submit();

As an alternative to $dollarsign notation, use a within block:

breast <- within(breast, {
  class <- as.numeric(as.character(class))
})

Note that you want to convert your vector to a character before converting it to a numeric. Simply calling as.numeric(class) will not the ids corresponding to each factor level (1, 2) rather than the levels themselves.

You don't need to use a subclass of Thread to make this work - take a look at the simple example I'm posting below to see how:

from threading import Thread
from time import sleep

def threaded_function(arg):
    for i in range(arg):
        print("running")
        sleep(1)


if __name__ == "__main__":
    thread = Thread(target = threaded_function, args = (10, ))
    thread.start()
    thread.join()
    print("thread finished...exiting")

Here I show how to use the threading module to create a thread which invokes a normal function as its target. You can see how I can pass whatever arguments I need to it in the thread constructor.

I know it's a old quetion but i got the same problem and fix it like this:

First, Add Fragment1 to BackStack with a name (e.g "Frag1"):

frag = new Fragment1();

transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.detailFragment, frag);
transaction.addToBackStack("Frag1");
transaction.commit();

And then, Whenever you want to go back to Fragment1 (even after adding 10 fragments above it), just call popBackStackImmediate with the name:

getSupportFragmentManager().popBackStackImmediate("Frag1", 0);

Hope it will help someone :)

Try to change directory to where the .box is saved

Run vagrant box add my-box downloaded.box, this may work as it avoids absolute path (on Windows?).

I actually had this error and could not find a solution. I actually ended up not doing an ajax request. I don't know if this issue was due to this being sub domain on my server or what. Here's my jquery.

            $('#deleteMeal').click(function(event) {
                var theId = $(event.currentTarget).attr("data-mealId");
                  $(function() {
                    $( "#filler" ).dialog({
                      resizable: false,
                      height:140,
                      modal: true,
                      buttons: {
                      "Are you sure you want to delete this Meal? Doing so will also delete this meal from other users Saved Meals.": function() {
                           $('#deleteMealLink').click();
//                         jQuery.ajax({
//                              url : 'http://www.mealog.com/mealtrist/meals/delete/' + theId,
//                              type : 'POST',
//                              success : function( response ) {
//                                  $("#container").replaceWith("<h1 style='color:red'>Your Meal Has Been Deleted</h1>");
//                              }
//                          });
                        // similar behavior as clicking on a link
                           window.location.href = 'http://www.mealog.com/mealtrist/meals/delete/' + theId;
                          $( this ).dialog( "close" );
                        },
                        Cancel: function() {
                          $( this ).dialog( "close" );
                        }
                      }
                    });
                  });
                });

So I actually set up an anchor to go to my API rather than doing a post request, which is what I figure most applications do.

  <p><a href="http://<?php echo $domain; ?>/mealtrist/meals/delete/{{ $meal->id }}" id="deleteMealLink" data-mealId="{{$meal->id}}" ></a></p>

Yes, statics are generally bad - generally, but in this case, the static is the most secure code you can write. Since the security context associates a Principal with the currently running thread, the most secure code would access the static from the thread as directly as possible. Hiding the access behind a wrapper class that is injected provides an attacker with more points to attack. They wouldn't need access to the code (which they would have a hard time changing if the jar was signed), they just need a way to override the configuration, which can be done at runtime or slipping some XML onto the classpath. Even using annotation injection in the signed code would be overridable with external XML. Such XML could inject the running system with a rogue principal. This is probably why Spring is doing something so un-Spring-like in this case.

I wanted to share the steps that I followed that fixed this issue for me in the hopes that it can help someone else (and also as a reminder for me in case something like this happens again)

The issues I'd been having (which were the same as OP's) may have to do with using homebrew to install Ruby.

To fix this, first I updated homebrew:

brew update && brew upgrade
brew doctor

(If brew doctor comes up with any issues, fix them first.) Then I uninstalled ruby

brew uninstall ruby

If rbenv is NOT installed at this point, then

brew install rbenv
brew install ruby-build
echo 'export RBENV_ROOT=/usr/local/var/rbenv' >> ~/.bash_profile
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile

Then I used rbenv to install ruby. First, find the desired version:

rbenv install -l

Install that version (e.g. 2.2.2)

rbenv install 2.2.2

Then set the global version to the desired ruby version:

rbenv global 2.2.2

At this point you should see the desired version set for the following commands:

rbenv versions

and

ruby --version

Now you should be able to install bundler:

gem install bundler

And once in the desired project folder, you can install all the required gems:

bundle
bundle install

As detailed in the Oracle Java SE Support Roadmap

After April 2015, Oracle will no longer post updates of Java SE 7 to its public download sites. Existing Java SE 7 downloads already posted as of April 2015 will remain accessible in the Java Archive

Check the Java SE 7 Archive Downloads page. The last release was update 80, therefore the 32-bit filename to download is jdk-7u80-windows-i586.exe (64-bit is named jdk-7u80-windows-x64.exe.

Old Java downloads also require a sign on to an Oracle account now :-( however with some crafty cookie creating one can use wget to grab the file without signing in.

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/7u80-b15/jdk-7u80-windows-i586.exe"

You might also consider adding ".

For example for %i in (*.wav) do opusenc "%~ni.wav" "%~ni.opus" is very good idea.

You can use IntEnum:

from enum import IntEnum

class Color(IntEnum):
   RED = 1
   BLUE = 2


print(int(Color.RED))   # prints 1

To get list of the ints:

enum_list = list(map(int, Color))
print(enum_list) # prints [1, 2]

Just one command did the work

netsh http add iplisten 127.0.0.1

The tricky part is a regex that includes a dash as one of the valid characters in a character class. The dash has to come immediately after the start for a (normal) character class and immediately after the caret for a negated character class. If you need a close square bracket too, then you need the close square bracket followed by the dash. Mercifully, you only need dash, hence the notation chosen.

grep '^[-d]rwx.*[0-9]$' "$@"

See: Regular Expressions and grep for POSIX-standard details.

Option 2 is a non-starter - you can't override fields, you can only hide them.

Personally, I'd go for option 1 every time. I try to keep fields private at all times. That's if you really need to be able to override the property at all, of course. Another option is to have a read-only property in the base class which is set from a constructor parameter:

abstract class Mother
{
    private readonly int myInt;
    public int MyInt { get { return myInt; } }

    protected Mother(int myInt)
    {
        this.myInt = myInt;
    }
}

class Daughter : Mother
{
    public Daughter() : base(1)
    {
    }
}

That's probably the most appropriate approach if the value doesn't change over the lifetime of the instance.

myDict = {}
for k in itertools.chain(A.keys(), B.keys()):
    myDict[k] = A.get(k, 0)+B.get(k, 0)

In addition to the already established answers, with ES6 arrow functions Promises turn from a modestly shining small blue dwarf straight into a red giant. That is about to collapse into a supernova:

api().then(result => api2()).then(result2 => api3()).then(result3 => console.log(result3))

As oligofren pointed out, without arguments between api calls you don't need the anonymous wrapper functions at all:

api().then(api2).then(api3).then(r3 => console.log(r3))

And finally, if you want to reach a supermassive black hole level, Promises can be awaited:

async function callApis() {
    let api1Result = await api();
    let api2Result = await api2(api1Result);
    let api3Result = await api3(api2Result);

    return api3Result;
}

I'm surprised that no one mentioned matplot. It's pretty convenient in case you don't need to plot each line in separate axes. Just one command:

matplot(y = data, type = 'l', lty = 1)

Use ?matplot to see all the options.

To add the legend, you can set color palette and then add it:

mypalette = rainbow(ncol(data))
matplot(y = data, type = 'l', lty = 1, col = mypalette)
legend(legend = colnames(data), x = "topright", y = "topright", lty = 1, lwd = 2, col = mypalette)

I found this brilliant solution here, it uses the simple logic NAN!=NAN. https://www.codespeedy.com/check-if-a-given-string-is-nan-in-python/

Using above example you can simply do the following. This should work on different type of objects as it simply utilize the fact that NAN is not equal to NAN.

 import numpy as np
 s = pd.Series(['apple', np.nan, 'banana'])
 s.apply(lambda x: x!=x)
 out[252]
 0    False
 1     True
 2    False
 dtype: bool

I/O bound refers to a condition in which the time it takes to complete a computation is determined principally by the period spent waiting for input/output operations to be completed.

This is the opposite of a task being CPU bound. This circumstance arises when the rate at which data is requested is slower than the rate it is consumed or, in other words, more time is spent requesting data than processing it.

mutil init function in one package execute order:

1. const and variable defined file init() function execute

2. init function execute order by the filename asc

If none of the other options works, then this could be an issue with the version of the JDK itself, just uninstall the current jdk and install the latest version.

I too faced this issue, after trying everything I upgraded to latest JDK, then this issue was resolved finally.

Instead of using ">" to redirect like this:

java Foo > log

use ">>" to append normal "stdout" output to a new or existing file:

java Foo >> log

However, if you also want to capture "stderr" errors (such as why the Java program couldn't be started), you should also use the "2>&1" tag which redirects "stderr" (the "2") to "stdout" (the "1"). For example:

java Foo >> log 2>&1 

The ssh2 functions aren't very good. Hard to use and harder yet to install, using them will guarantee that your code has zero portability. My recommendation would be to use phpseclib, a pure PHP SFTP implementation.

You need to query the data dictionary, specifically the USER_CONS_COLUMNS view to see the table columns and corresponding constraints:

SELECT *
  FROM user_cons_columns
 WHERE table_name = '<your table name>';

FYI, unless you specifically created your table with a lower case name (using double quotes) then the table name will be defaulted to upper case so ensure it is so in your query.

If you then wish to see more information about the constraint itself query the USER_CONSTRAINTS view:

SELECT *
  FROM user_constraints
 WHERE table_name = '<your table name>'
   AND constraint_name = '<your constraint name>';

If the table is held in a schema that is not your default schema then you might need to replace the views with:

all_cons_columns

and

all_constraints

adding to the where clause:

   AND owner = '<schema owner of the table>'

You can probably just use the true command:

if [ "$a" -ge 10 ]; then
    true
elif [ "$a" -le 5 ]; then
    echo "1"
else
    echo "2"
fi

An alternative, in your example case (but not necessarily everywhere) is to re-order your if/else:

if [ "$a" -le 5 ]; then
    echo "1"
elif [ "$a" -lt 10 ]; then
    echo "2"
fi

Use nargs='?' (or nargs='*' if you need more than one dir)

parser.add_argument('dir', nargs='?', default=os.getcwd())

extended example:

>>> import os, argparse
>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('-v', action='store_true')
_StoreTrueAction(option_strings=['-v'], dest='v', nargs=0, const=True, default=False, type=None, choices=None, help=None, metavar=None)
>>> parser.add_argument('dir', nargs='?', default=os.getcwd())
_StoreAction(option_strings=[], dest='dir', nargs='?', const=None, default='/home/vinay', type=None, choices=None, help=None, metavar=None)
>>> parser.parse_args('somedir -v'.split())
Namespace(dir='somedir', v=True)
>>> parser.parse_args('-v'.split())
Namespace(dir='/home/vinay', v=True)
>>> parser.parse_args(''.split())
Namespace(dir='/home/vinay', v=False)
>>> parser.parse_args(['somedir'])
Namespace(dir='somedir', v=False)
>>> parser.parse_args('somedir -h -v'.split())
usage: [-h] [-v] [dir]

positional arguments:
  dir

optional arguments:
  -h, --help  show this help message and exit
  -v

If you need to frequently use LIKE, you can simplify the problem a bit. A custom method like () can be created in the model that inherits the Eloquent ORM:

public  function scopeLike($query, $field, $value){
        return $query->where($field, 'LIKE', "%$value%");
}

So then you can use this method in such way:

User::like('name', 'Tomas')->get();

Set texts with different sizes and styles, and size and style for texts from cells ( with Range)

As of AngularJS 1.2 there's a directive called ng-repeat-start that does exactly what you ask for. See my answer in this question for a description of how to use it.
