LPCWSTR stands for "Long Pointer to Constant Wide String". The W stands for Wide and means that the string is stored in a 2 byte character vs. the normal char. Common for any C/C++ code that has to deal with non-ASCII only strings.=

To get a normal C literal string to assign to a LPCWSTR, you need to prefix it with L

LPCWSTR a = L"TestWindow";

For your actual form, if you were to just post the results to your same page, it should probably work out all right. Try something like:

<form action=<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> method="POST>

While in Java it's indeed a bad practice to use exceptions for flow control (mainly because exceptions force the JVM to gather resources (more here)), in Python you have two important principles: duck typing and EAFP. This basically means that you are encouraged to try using an object the way you think it would work, and handle when things are not like that.

In summary, the only problem would be your code getting too much indented. If you feel like it, try to simplify some of the nestings, like lqc suggested in the suggested answer above.

Specifically...

How and where is app.run() used? After module definition or after app.config(), after app.controller()?

Where:

In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js

How:

Make it look like this

var app = angular.module('mean.dashboard', ['ui.bootstrap']);

app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
    function($scope, Global, Dashboard) {
        $scope.global = Global;
        $scope.package = {
            name: 'dashboard'
        };
        // ...
    }
]);

app.run(function(editableOptions) {
    editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});

The endpoint of the term is the URL that is focused on creating a request. Take a look at the following examples from different points:

/api/groups/6/workings/1
/api/v2/groups/5/workings/2
/api/workings/3

They can clearly access the same source in a given API.

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");

You can confirm this by printing out the string to see that it turns out identical to the first case.

Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string, which would make it look perhaps like this:

$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
               mysql_real_escape_string($prefix));
$query = mysql_query($sql);

Note that inside the first argument of sprintf the percent sign needs to be doubled to end up appearing once in the result.

Option1:

Start the console and execute this:

db.version()

Option2:

Open a shell console and do:

$ mongod --version

It will show you something like

$ mongod --version
db version v3.0.2

Implement Comparable interface to Fruit.

public class Fruit implements Comparable<Fruit> {

It implements the method

@Override
    public int compareTo(Fruit fruit) {
        //write code here for compare name
    }

Then do call sort method

Collections.sort(fruitList);

Bash alias does not directly accept parameters. You will have to create a function.

alias does not accept parameters but a function can be called just like an alias. For example:

myfunction() {
    #do things with parameters like $1 such as
    mv "$1" "$1.bak"
    cp "$2" "$1"
}


myfunction old.conf new.conf #calls `myfunction`

By the way, Bash functions defined in your .bashrc and other files are available as commands within your shell. So for instance you can call the earlier function like this

$ myfunction original.conf my.conf

There is an issue open with respect to this.

For now, the solution works for me: create a empty folder locally and synchronize it with the remote one.

Here is a sample playbook:

- name: "Empty directory"
  hosts: *
  tasks:
    - name: "Create an empty directory (locally)"
      local_action:
        module: file
        state: directory
        path: "/tmp/empty"

    - name: Empty remote directory
      synchronize:
        src: /tmp/empty/
        dest: /home/mydata/web/
        delete: yes
        recursive: yes

as explained here

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

Add your php folder path to the System PATH and everything should work fine. It will also fix some other extensions that are broken.

Try javax.net.ssl.keyStorePassword instead of javax.net.ssl.keyPassword: the latter isn't mentioned in the JSSE ref guide.

The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmExceptions are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.

You could also use -Djavax.net.debug=ssl, or at least -Djavax.net.debug=ssl,keymanager, to get more debugging information, if the information in the stack trace isn't sufficient.

Don't do this use a dictionary

import sys
this = sys.modules[__name__] # this is now your current namespace
for x in range(0,9):
    setattr(this, 'string%s' % x, 'Hello')

print string0
print string1
print string2
print string3
print string4
print string5
print string6
print string7
print string8

don't do this use a dict

globals() has risk as it gives you what the namespace is currently pointing to but this can change and so modifying the return from globals() is not a good idea

if you build an MVC project, its included by default. otherwise, what Nick said.

If you're doing fragment caching, you can manually break the cache by updating your cache key, like so:

Version #1

<% cache ['cool_name_for_cache_key', 'v1'] do %>

Version #2

<% cache ['cool_name_for_cache_key', 'v2'] do %>

Or you can have the cache automatically reset based on the state of a non-static object, such as an ActiveRecord object, like so:

<% cache @user_object do %>

With this ^ method, any time the user object is updated, the cache will automatically be reset.

I think this gives you the total list of all files in the repo history:

git rev-list --objects --all | git cat-file --batch-check="%(objectsize) %(rest)" | cut -d" " -f1 | paste -s -d + - | bc

You can replace --all with a treeish (HEAD, origin/master, etc.) to calculate the size of a branch.

There is a rather clever solution:

#define MACRO(X,Y)                         \
do {                                       \
  cout << "1st arg is:" << (X) << endl;    \
  cout << "2nd arg is:" << (Y) << endl;    \
  cout << "Sum is:" << ((X)+(Y)) << endl;  \
} while (0)

Now you have a single block-level statement, which must be followed by a semicolon. This behaves as expected and desired in all three examples.

xsd.exe as mentioned by Marc Gravell. The fastest way to get up and running IMO.

Or if you need more flexibility/options :

xsd2code VS add-in (Codeplex)

Since the question mentions VirtualBox, this one works currently:

VBoxManage convertfromraw imagefile.dd vmdkname.vmdk --format VMDK

Run it without arguments for a few interesting details (notably the --variant flag):

VBoxManage convertfromraw

This is older but placing this here for my reference too. boto3.resource is just implementing the default Session, you can pass through boto3.resource session details.

Help on function resource in module boto3:

resource(*args, **kwargs)
    Create a resource service client by name using the default session.

    See :py:meth:`boto3.session.Session.resource`.

https://github.com/boto/boto3/blob/86392b5ca26da57ce6a776365a52d3cab8487d60/boto3/session.py#L265

you can see that it just takes the same arguments as Boto3.Session

import boto3
S3 = boto3.resource('s3', region_name='us-west-2', aws_access_key_id=settings.AWS_SERVER_PUBLIC_KEY, aws_secret_access_key=settings.AWS_SERVER_SECRET_KEY)
S3.Object( bucket_name, key_name ).delete()

maybe if you want array value to be your object key too

function toObject(arr) {
  var rv = {};
  for (var i = 0; i < arr.length; ++i)
    rv[arr[i]] = arr[i];
  return rv;
}

You can also have a look at FLTK (C++ and not plain C though)

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation.

FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

Here are some quickstart screencasts

[Happy New Year!]

No version 2 doesn't actually work but if you want this kind of approach you can do the following (probably not the speediest, but arguably more intuitive):

switch (true) {
case ($var === 'something' || $var === 'something else'):
// do some stuff
break;
}

Don't ever use the setInterval or setTimeout functions for time measuring! They are unreliable, and it is very likely that the JS execution scheduling during a documents parsing and displaying is delayed.

Instead, use the Date object to create a timestamp when you page began loading, and calculate the difference to the time when the page has been fully loaded:

<doctype html>
<html>
    <head>
        <script type="text/javascript">
            var timerStart = Date.now();
        </script>
        <!-- do all the stuff you need to do -->
    </head>
    <body>
        <!-- put everything you need in here -->

        <script type="text/javascript">
             $(document).ready(function() {
                 console.log("Time until DOMready: ", Date.now()-timerStart);
             });
             $(window).load(function() {
                 console.log("Time until everything loaded: ", Date.now()-timerStart);
             });
        </script>
    </body>
</html>

NPS (Node Package Scripts) solved this problem for me. It lets you put your NPM scripts into a separate JavaScript file, where you can add comments galore and any other JavaScript logic you need to. https://www.npmjs.com/package/nps

Sample of the package-scripts.js from one of my projects

module.exports = {
  scripts: {
    // makes sure e2e webdrivers are up to date
    postinstall: 'nps webdriver-update',

    // run the webpack dev server and open it in browser on port 7000
    server: 'webpack-dev-server --inline --progress --port 7000 --open',

    // start webpack dev server with full reload on each change
    default: 'nps server',

    // start webpack dev server with hot module replacement
    hmr: 'nps server -- --hot',

    // generates icon font via a gulp task
    iconFont: 'gulp default --gulpfile src/deps/build-scripts/gulp-icon-font.js',

    // No longer used
    // copyFonts: 'copyfiles -f src/app/glb/font/webfonts/**/* dist/1-0-0/font'
  }
}

I just did a local install npm install nps -save-dev and put this in my package.json scripts.

"scripts": {
    "start": "nps",
    "test": "nps test"
}

Pretty easy, go to the 'scripts' tab. And select the source file you want and double-click any line to edit it.

Late answer but can be helpful

function areThereDuplicates(args) {

    let count = {};
    for(let i = 0; i < args.length; i++){
         count[args[i]] = 1 + (count[args[i]] || 0);
    }
    let found = Object.keys(count).filter(function(key) {
        return count[key] > 1;
    });
    return found.length ? true : false; 
}

areThereDuplicates([1,2,5]);

var $list = $('#divname input[id^="q17_"]');   // get all input controls with id q17_

// once you have $list you can do whatever you want

var ControlCnt = $list.length;
// Now loop through list of controls
$list.each( function() {

    var id = $(this).prop("id");      // get id
    var cbx = '';
    if ($(this).is(':checkbox') || $(this).is(':radio')) {
        // Need to see if this control is checked
    }
    else { 
        // Nope, not a checked control - so do something else
    }

});

var string = "Hi welcome to stack overflow"
var toSearch = "stack"

//case insensitive search

var result = string.search(new RegExp(toSearch, "i")) > 0 ? 'Matched' : 'notMatched'

Hope this helps

I am using this one with my codes.

Simply add this to your criteria:

criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

that code will be like the select distinct * from table of the native sql. Hope this one helps.

SELECT 0+COALESCE(SUM(Price),0) AS TotalPrice
FROM Inventory
WHERE (DateAdded BETWEEN @StartDate AND @EndDate)

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

I recommend that before executing SaveAs, delete the file it exists.

If Dir("f:ull\path\with\filename.xls") <> "" Then
    Kill "f:ull\path\with\filename.xls"
End If

It's easier than setting DisplayAlerts off and on, plus if DisplayAlerts remains off due to code crash, it can cause problems if you work with Excel in the same session.

If you're needing to test remote urls in an input field, you can try testing a simple regex with the types that you're interested in.

$input_field = $('.js-input-field-class');

if ( !(/\.(gif|jpg|jpeg|tiff|png)$/i).test( $input_field.val() )) {
  $('.error-message').text('This URL is not a valid image type. Please use a url with the known image types gif, jpg, jpeg, tiff or png.');
  return false;
}

This will capture anything ending in .gif, .jpg, .jpeg, .tiff or .png

I should note that some popular sites like Twitter append a size attribute to the end of their images. For instance, the following would fail this test even though it's a valid image type:

https://pbs.twimg.com/media/BrTuXT5CUAAtkZM.jpg:large

Because of that, this isn't a perfect solution. But it will get you to about 90% of the way.

The same as you would in .NET:

$DateStr = $Date.ToString("yyyyMMdd")

Or:

$DateStr = '{0:yyyyMMdd}' -f $Date

To help debug, and make your code better, do this:

private void processLine(String[] strings) {
    Integer[] intarray=new Integer[strings.length];
    int i=0;
    for(String str:strings){
        try {
            intarray[i]=Integer.parseInt(str);
            i++;
        } catch (NumberFormatException e) {
            throw new IllegalArgumentException("Not a number: " + str + " at index " + i, e);
        }
    }
}

Also, from a code neatness point, you could reduce the lines by doing this:

for (String str : strings)
    intarray[i++] = Integer.parseInt(str);

Laravel 5

This is working for me (i use laravel 5.6).

$collection = MyModel::all()->groupBy('column');

If you want to convert the collection to plain php array, you can use toArray()

$array = MyModel::all()->groupBy('column')->toArray();

To those that are incline to use GUI:

Click Right mouse button on procecdure name then select Test

Then in new window you will see script generated just add the parameters and click on Start Debugger or F9

Hope this saves you some time.

This function returns the actual used range to the lower right limit. It returns "Nothing" if the sheet is empty.

'2020-01-26
Function fUsedRange() As Range
Dim lngLastRow As Long
Dim lngLastCol As Long
Dim rngLastCell As Range
    On Error Resume Next
    Set rngLastCell = ActiveSheet.Cells.Find("*", searchorder:=xlByRows, searchdirection:=xlPrevious)
    If rngLastCell Is Nothing Then  'look for data backwards in rows
        Set fUsedRange = Nothing
        Exit Function
    Else
        lngLastRow = rngLastCell.Row
    End If
    Set rngLastCell = ActiveSheet.Cells.Find("*", searchorder:=xlByColumns, searchdirection:=xlPrevious)
    If rngLastCell Is Nothing Then  'look for data backwards in columns
        Set fUsedRange = Nothing
        Exit Function
    Else
        lngLastCol = rngLastCell.Column
    End If
    Set fUsedRange = ActiveSheet.Range(Cells(1, 1), Cells(lngLastRow, lngLastCol))  'set up range
End Function

Actually, You can achieve this with current typescript:

type Grow<T, A extends Array<T>> = ((x: T, ...xs: A) => void) extends ((...a: infer X) => void) ? X : never;
type GrowToSize<T, A extends Array<T>, N extends number> = { 0: A, 1: GrowToSize<T, Grow<T, A>, N> }[A['length'] extends N ? 0 : 1];

export type FixedArray<T, N extends number> = GrowToSize<T, [], N>;

Examples:

// OK
const fixedArr3: FixedArray<string, 3> = ['a', 'b', 'c'];

// Error:
// Type '[string, string, string]' is not assignable to type '[string, string]'.
//   Types of property 'length' are incompatible.
//     Type '3' is not assignable to type '2'.ts(2322)
const fixedArr2: FixedArray<string, 2> = ['a', 'b', 'c'];

// Error:
// Property '3' is missing in type '[string, string, string]' but required in type 
// '[string, string, string, string]'.ts(2741)
const fixedArr4: FixedArray<string, 4> = ['a', 'b', 'c'];

EDIT (after a long time)

This should handle bigger sizes (as basically it grows array exponentially until we get to closest power of two):

type Shift<A extends Array<any>> = ((...args: A) => void) extends ((...args: [A[0], ...infer R]) => void) ? R : never;

type GrowExpRev<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExpRev<[...A, ...P[0]], N, P>,
  1: GrowExpRev<A, N, Shift<P>>
}[[...A, ...P[0]][N] extends undefined ? 0 : 1];

type GrowExp<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExp<[...A, ...A], N, [A, ...P]>,
  1: GrowExpRev<A, N, P>
}[[...A, ...A][N] extends undefined ? 0 : 1];

export type FixedSizeArray<T, N extends number> = N extends 0 ? [] : N extends 1 ? [T] : GrowExp<[T, T], N, [[T]]>;

How to change commits deeper in history

Since history in Git is immutable, fixing anything but the most recent commit (commit which is not branch head) requires that the history is rewritten from the changed commit and forward.

You can use StGIT for that, initialize branch if necessary, uncommitting up to the commit you want to change, pop to it if necessary, make a change then refresh patch (with -e option if you want to correct commit message), then push everything and stg commit.

Or you can use rebase to do that. Create new temporary branch, rewind it to the commit you want to change using git reset --hard, change that commit (it would be top of current head), then rebase branch on top of changed commit, using git rebase --onto .

Or you can use git rebase --interactive, which allows various modifications like patch re-ordering, collapsing, ...

I think that should answer your question. However, note that if you have pushed code to a remote repository and people have pulled from it, then this is going to mess up their code histories, as well as the work they've done. So do it carefully.

The use of @Qualifier will solve the issue.
Explained as below example : 
public interface PersonType {} // MasterInterface

@Component(value="1.2") 
public class Person implements  PersonType { //Bean implementing the interface
@Qualifier("1.2")
    public void setPerson(PersonType person) {
        this.person = person;
    }
}

@Component(value="1.5")
public class NewPerson implements  PersonType { 
@Qualifier("1.5")
    public void setNewPerson(PersonType newPerson) {
        this.newPerson = newPerson;
    }
}

Now get the application context object in any component class :

Object obj= BeanFactoryAnnotationUtils.qualifiedBeanOfType((ctx).getAutowireCapableBeanFactory(), PersonType.class, type);//type is the qualifier id

you can the object of class of which qualifier id is passed.

Here is the way to do it:

#!/bin/sh

abort()
{
    echo >&2 '
***************
*** ABORTED ***
***************
'
    echo "An error occurred. Exiting..." >&2
    exit 1
}

trap 'abort' 0

set -e

# Add your script below....
# If an error occurs, the abort() function will be called.
#----------------------------------------------------------
# ===> Your script goes here
# Done!
trap : 0

echo >&2 '
************
*** DONE *** 
************
'

Extend HttpServletRequestWrapper, override the header getters to return the parameters as well:

public class AddParamsToHeader extends HttpServletRequestWrapper {
    public AddParamsToHeader(HttpServletRequest request) {
        super(request);
    }

    public String getHeader(String name) {
        String header = super.getHeader(name);
        return (header != null) ? header : super.getParameter(name); // Note: you can't use getParameterValues() here.
    }

    public Enumeration getHeaderNames() {
        List<String> names = Collections.list(super.getHeaderNames());
        names.addAll(Collections.list(super.getParameterNames()));
        return Collections.enumeration(names);
    }
}

..and wrap the original request with it:

chain.doFilter(new AddParamsToHeader((HttpServletRequest) request), response);

That said, I personally find this a bad idea. Rather give it direct access to the parameters or pass the parameters to it.

The pageContext is an implicit object available in JSPs. The EL documentation says

The context for the JSP page. Provides access to various objects including:
servletContext: ...
session: ...
request: ...
response: ...

Thus this expression will get the current HttpServletRequest object and get the context path for the current request and append /JSPAddress.jsp to it to create a link (that will work even if the context-path this resource is accessed at changes).

The primary purpose of this expression would be to keep your links 'relative' to the application context and insulate them from changes to the application path.

For example, if your JSP (named thisJSP.jsp) is accessed at http://myhost.com/myWebApp/thisJSP.jsp, thecontext path will be myWebApp. Thus, the link href generated will be /myWebApp/JSPAddress.jsp.

If someday, you decide to deploy the JSP on another server with the context-path of corpWebApp, the href generated for the link will automatically change to /corpWebApp/JSPAddress.jsp without any work on your part.

Look closely at the two dashes in

unzipRelease –Src '$ReleaseFile' -Dst '$Destination'

This first one is not a normal dash but an en-dash (– in HTML). Replace that with the dash found before Dst.

You can use retainAll method and get the intersection of your two sets.

I think you can use

sys.exit(0)

You may check it here in the python 2.7 doc:

The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like.

Use unlist with use.names = FALSE argument.

unlist(myList, use.names=FALSE)

StringUtils.isBlank(foo) will perform a null check for you. If you perform foo.isEmpty() and foo is null, you will raise a NullPointerException.

compileSdkVersion : The compileSdkVersion is the version of the API the app is compiled against. This means you can use Android API features included in that version of the API (as well as all previous versions, obviously). If you try and use API 16 features but set compileSdkVersion to 15, you will get a compilation error. If you set compileSdkVersion to 16 you can still run the app on a API 15 device.

minSdkVersion : The min sdk version is the minimum version of the Android operating system required to run your application.

targetSdkVersion : The target sdk version is the version your app is targeted to run on.

In fact, most compilers emit the same code for both functions calls, because references are generally implemented using pointers.

Following this logic, when an argument of (non-const) reference type is used in the function body, the generated code will just silently operate on the address of the argument and it will dereference it. In addition, when a call to such a function is encountered, the compiler will generate code that passes the address of the arguments instead of copying their value.

Basically, references and pointers are not very different from an implementation point of view, the main (and very important) difference is in the philosophy: a reference is the object itself, just with a different name.

References have a couple more advantages compared to pointers (e. g. they can't be NULL, so they are safer to use). Consequently, if you can use C++, then passing by reference is generally considered more elegant and it should be preferred. However, in C, there's no passing by reference, so if you want to write C code (or, horribile dictu, code that compiles with both a C and a C++ compiler, albeit that's not a good idea), you'll have to restrict yourself to using pointers.

I'd use a button to trigger the input:

<button onclick="document.getElementById('fileUpload').click()">Open from File...</button>
<input type="file" id="fileUpload" name="files" style="display:none" />

Quick and clean.

The main use of -f is to force the removal of files that would not be removed using rm by itself (as a special case, it "removes" non-existent files, thus suppressing the error message).

You can also just redirect the error message using

$ rm file.txt 2> /dev/null

(or your operating system's equivalent). You can check the value of $? immediately after calling rm to see if a file was actually removed or not.

rm -r recurses into directories, but only the directories you give to rm. It will also delete those directories. One solution is:

for i in $( find . -name *.pyc )
do
  rm $i
done

find will find all *.pyc files recursively in the current directory, and the for loop will iterate through the list of files found, removing each one.

Well, you can't add styling using pseudo selectors like :hover, :after, :nth-child, or anything like that using jQuery.

If you want to add a CSS rule like that you have to create a <style> element and add that :hover rule to it just like you would in CSS. Then you would have to add that <style> element to the page.

Using the .hover function seems to be more appropriate if you can't just add the css to a stylesheet, but if you insist you can do:

$('head').append('<style>.myclass:hover div {background-color : red;}</style>')

If you want to read more on adding CSS with javascript you can check out one of David Walsh's Blog posts.

you can go to project properties --> configuration properties --> General -->Project default and there change the "Character set" from "Unicode" to "Not set".

Another one simple method is there. You don't need to code more in CSS. Just including a java script and entering the div "id" inside the script you can get equal height of columns so that you can have the height fit to container. It works in major browsers.

modify in the above line its enough.

Try this.

I have JSONObject like this: {"status":[{"Response":"success"}]}.

If I want to convert the JSONObject value, which is a JSONArray into JSONObject automatically without using any static value, here is the code for that.

JSONArray array=new JSONArray();
JSONObject obj2=new JSONObject();
obj2.put("Response", "success");
array.put(obj2);
JSONObject obj=new JSONObject();
obj.put("status",array);

Converting the JSONArray to JSON Object:

Iterator<String> it=obj.keys();
        while(it.hasNext()){
String keys=it.next();
JSONObject innerJson=new JSONObject(obj.toString());
JSONArray innerArray=innerJson.getJSONArray(keys);
for(int i=0;i<innerArray.length();i++){
JSONObject innInnerObj=innerArray.getJSONObject(i);
Iterator<String> InnerIterator=innInnerObj.keys();
while(InnerIterator.hasNext()){
System.out.println("InnInnerObject value is :"+innInnerObj.get(InnerIterator.next()));


 }
}

Here it is:

s = "123"
try:
  i = int(s)
except ValueError as verr:
  pass # do job to handle: s does not contain anything convertible to int
except Exception as ex:
  pass # do job to handle: Exception occurred while converting to int

The short answer is:

1. choose the iOS scheme from the drop-down near the run button from the menu bar
2. choose product > archive in the window that pops-up
3. click 'validate'
4. upon successful validation, click 'submit'

Requests doesn't have an equivalent to Urlib2's read().

>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True

It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.

Edit for Python 3:

Python now handles data types differently. response.content returns a sequence of bytes (integers that represent ASCII) while response.text is a string (sequence of chars).

Thus,

>>> print response.content == response.text
False

>>> print str(response.content) == response.text
True

from datetime import datetime, timedelta

nine_hours_from_now = datetime.now() + timedelta(hours=9)
#datetime.datetime(2012, 12, 3, 23, 24, 31, 774118)

And then use string formatting to get the relevant pieces:

>>> '{:%H:%M:%S}'.format(nine_hours_from_now)
'23:24:31'

If you're only formatting the datetime then you can use:

>>> format(nine_hours_from_now, '%H:%M:%S')
'23:24:31'

Or, as @eumiro has pointed out in comments - strftime

If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").

Try using * unpack, like below:

>>> a=set('abcde')
>>> a
{'a', 'd', 'e', 'b', 'c'}
>>> l=['f','g']
>>> l
['f', 'g']
>>> {*l, *a}
{'a', 'd', 'e', 'f', 'b', 'g', 'c'}
>>> 

Non Editor version:

a=set('abcde')
l=['f', 'g']
print({*l, *a})

Output:

{'a', 'd', 'e', 'f', 'b', 'g', 'c'}

$('#div').scroll(function () {
   if ($(this).scrollTop() + $(this).innerHeight() >= $(this)[0].scrollHeight-1) {

     //fire your event


    }
}

Basic rule says that :

For Entities with generated identifier :

save() : It returns an entity's identifier immediately in addition to making the object persistent. So an insert query is fired immediately.

persist() : It returns the persistent object. It does not have any compulsion of returning the identifier immediately so it does not guarantee that insert will be fired immediately. It may fire an insert immediately but it is not guaranteed. In some cases, the query may be fired immediately while in others it may be fired at session flush time.

For Entities with assigned identifier :

save(): It returns an entity's identifier immediately. Since the identifier is already assigned to entity before calling save, so insert is not fired immediately. It is fired at session flush time.

persist() : same as save. It also fire insert at flush time.

Suppose we have an entity which uses a generated identifier as follows :

@Entity
@Table(name="USER_DETAILS")
public class UserDetails {
    @Id
    @Column(name = "USER_ID")
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int userId;

    @Column(name = "USER_NAME")
    private String userName;

    public int getUserId() {
        return userId;
    }
    public void setUserId(int userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
}

save() :

    Session session = sessionFactory.openSession();
    session.beginTransaction();
    UserDetails user = new UserDetails();
    user.setUserName("Gaurav");
    session.save(user); // Query is fired immediately as this statement is executed.
    session.getTransaction().commit();
    session.close();

persist() :

    Session session = sessionFactory.openSession();
    session.beginTransaction();
    UserDetails user = new UserDetails();
    user.setUserName("Gaurav");
    session.persist(user); // Query is not guaranteed to be fired immediately. It may get fired here.
    session.getTransaction().commit(); // If it not executed in last statement then It is fired here.
    session.close();

Now suppose we have the same entity defined as follows without the id field having generated annotation i.e. ID will be assigned manually.

@Entity
@Table(name="USER_DETAILS")
public class UserDetails {
    @Id
    @Column(name = "USER_ID")
    private int userId;

    @Column(name = "USER_NAME")
    private String userName;

    public int getUserId() {
        return userId;
    }
    public void setUserId(int userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
}

for save() :

Session session = sessionFactory.openSession();
session.beginTransaction();
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("Gaurav");
session.save(user); // Query is not fired here since id for object being referred by user is already available. No query need to be fired to find it. Data for user now available in first level cache but not in db.
session.getTransaction().commit();// Query will be fired at this point and data for user will now also be available in DB
session.close();

for persist() :

Session session = sessionFactory.openSession();
session.beginTransaction();
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("Gaurav");
session.persist(user); // Query is not fired here.Object is made persistent. Data for user now available in first level cache but not in db.
session.getTransaction().commit();// Query will be fired at this point and data for user will now also be available in DB
session.close();

The above cases were true when the save or persist were called from within a transaction.

The other points of difference between save and persist are :

1. save() can be called outside a transaction. If assigned identifier is used then since id is already available, so no insert query is immediately fired. The query is only fired when the session is flushed.

2. If generated identifier is used , then since id need to generated, insert is immediately fired. But it only saves the primary entity. If the entity has some cascaded entities then those will not be saved in db at this point. They will be saved when the session is flushed.

3. If persist() is outside a transaction then insert is fired only when session is flushed no matter what kind of identifier (generated or assigned) is used.

4. If save is called over a persistent object, then the entity is saved using update query.

var x = condition || null;

I'm usually facing this problem when dealing with events from an input field, like key up. But remember that the event could stem from anywhere, e.g. from a keyup listener on document, where there is no associated value. So in order to correctly provide the information I'd provide an additional type:

interface KeyboardEventOnInputField extends KeyboardEvent {
  target: HTMLInputElement;
}
...

  onKeyUp(e: KeyboardEventOnInputField) {
    const inputValue = e.target.value;
    ...
  }

If the input to the function has a type of Event, you might need to tell typescript what it actually is:

  onKeyUp(e: Event) {
    const evt = e as KeyboardEventOnInputField;
    const inputValue = evt.target.value;
    this.inputValue.next(inputValue);
  }

This is for example required in Angular.

Windows 10 Home Edition does not have Local Users and Groups option so that is the reason you aren't able to see that in Computer Management.

You can use User Accounts by pressing Window+R, typing netplwiz and pressing OK as described here.

I would recommend you google 'Read objects in folder'. You might need to create a reader and a list and let the reader read all the object names in the folder and add them to the list in n loops.

My problem was also the mysql.sock-file.

Chrome developer tools has this feature built-in. Bring up the developer tools (pressing F12 is one way), in the Sources tab, the bottom left bar has a set of icons. The "{}" icon is "Pretty print" and does this conversion on demand.

If you treat the content as text, not HTML, then DOM operations should cause the data to be properly encoded. Here's how you'd do it in jQuery:

$('#container').text(xmlString);

Here's how you'd do it with standard DOM methods:

document.getElementById('container')
        .appendChild(document.createTextNode(xmlString));

If you're placing the XML inside of HTML through server-side scripting, there are bound to be encoding functions to allow you to do that (if you add what your server-side technology is, we can give you specific examples of how you'd do it).

The easiest way is to use a for loop template tag.

Given the view:

def MyView(request):
    ...
    query_results = YourModel.objects.all()
    ...
    #return a response to your template and add query_results to the context

You can add a snippet like this your template...

<table>
    <tr>
        <th>Field 1</th>
        ...
        <th>Field N</th>
    </tr>
    {% for item in query_results %}
    <tr> 
        <td>{{ item.field1 }}</td>
        ...
        <td>{{ item.fieldN }}</td>
    </tr>
    {% endfor %}
</table>

This is all covered in Part 3 of the Django tutorial. And here's Part 1 if you need to start there.

Not recommended for serious deployments, but here is essentially a "wait x seconds" command.

With docker-compose version 3.4 a start_period instruction has been added to healthcheck. This means we can do the following:

docker-compose.yml:

version: "3.4"
services:
  # your server docker container
  zmq_server:
    build:
      context: ./server_router_router
      dockerfile: Dockerfile

  # container that has to wait
  zmq_client:
    build:
      context: ./client_dealer/
      dockerfile: Dockerfile
    depends_on:
      - zmq_server
    healthcheck:
      test: "sh status.sh"
      start_period: 5s

status.sh:

#!/bin/sh

exit 0

What happens here is that the healthcheck is invoked after 5 seconds. This calls the status.sh script, which always returns "No problem". We just made zmq_client container wait 5 seconds before starting!

Note: It's important that you have version: "3.4". If the .4 is not there, docker-compose complains.

Try this.

EditText text = (EditText)findViewById(R.id.edittext1);
String  str = text.getText().toString().trim();

You should always guarantee that if two objects are equal, as defined by Equals(), they should return the same hash code. As some of the other comments state, in theory this is not mandatory if the object will never be used in a hash based container like HashSet or Dictionary. I would advice you to always follow this rule though. The reason is simply because it is way too easy for someone to change a collection from one type to another with the good intention of actually improving the performance or just conveying the code semantics in a better way.

For example, suppose we keep some objects in a List. Sometime later someone actually realizes that a HashSet is a much better alternative because of the better search characteristics for example. This is when we can get into trouble. List would internally use the default equality comparer for the type which means Equals in your case while HashSet makes use of GetHashCode(). If the two behave differently, so will your program. And bear in mind that such issues are not the easiest to troubleshoot.

I've summarized this behavior with some other GetHashCode() pitfalls in a blog post where you can find further examples and explanations.

So, here is the deal:

When making

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Config.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();

You are passing GsonConverterFactory.create() here. If you do it like this, Gson will automatically convert the json object you get in response to your object <ResponseBody>. Here you can pass all other converters such as Jackson, etc...

C++, for two reasons.

1) a lot of games are programmed in C++. No mainstream game is, as yet, programmed in a managed language.

2) C++ is as hard as it gets. You have to master manual memory management and generally no bounds checking (beyond the excellent Valgrind!). If you master C++, you will find this transferable to managed procedural languages. Less so the other way around.

C++ has a level of complexity close to APL! You'll never get better by playing weaker opponents.

Joel makes a very strong point about this. People who understand how the machine works make better programmers, because all abstractions are leaky.

Using set elements ... isn't always the best way. It would be useful if there were a distinct set string-elements ....

So, I use these functions in my .gdbinit:

define pstr
  ptype $arg0._M_dataplus._M_p
  printf "[%d] = %s\n", $arg0._M_string_length, $arg0._M_dataplus._M_p
end

define pcstr
  ptype $arg0
  printf "[%d] = %s\n", strlen($arg0), $arg0
end

Caveats:

• The first is c++ lib dependent as it accesses members of std::string, but is easily adjusted.
• The second can only be used on a running program as it calls strlen.

Standard SQL disallows references to column aliases in a WHERE clause. This restriction is imposed because when the WHERE clause is evaluated, the column value may not yet have been determined. For example, the following query is illegal:

SELECT id, COUNT(*) AS cnt FROM tbl_name WHERE cnt > 0 GROUP BY id;

First of all you should verify that you have no excess virtual hosts in your httpd-vhosts file. I mean following simple rule: 1 project = 1 virtual host in config file. Otherwise you'll face with error even if you'll change ports etc.

Starting in Python 2.6, there is an alternative: the str.format() method. Here are some examples using the existing string format operator (%):

>>> "Name: %s, age: %d" % ('John', 35) 
'Name: John, age: 35' 
>>> i = 45 
>>> 'dec: %d/oct: %#o/hex: %#X' % (i, i, i) 
'dec: 45/oct: 055/hex: 0X2D' 
>>> "MM/DD/YY = %02d/%02d/%02d" % (12, 7, 41) 
'MM/DD/YY = 12/07/41' 
>>> 'Total with tax: $%.2f' % (13.00 * 1.0825) 
'Total with tax: $14.07' 
>>> d = {'web': 'user', 'page': 42} 
>>> 'http://xxx.yyy.zzz/%(web)s/%(page)d.html' % d 
'http://xxx.yyy.zzz/user/42.html' 

Here are the equivalent snippets but using str.format():

>>> "Name: {0}, age: {1}".format('John', 35) 
'Name: John, age: 35' 
>>> i = 45 
>>> 'dec: {0}/oct: {0:#o}/hex: {0:#X}'.format(i) 
'dec: 45/oct: 0o55/hex: 0X2D' 
>>> "MM/DD/YY = {0:02d}/{1:02d}/{2:02d}".format(12, 7, 41) 
'MM/DD/YY = 12/07/41' 
>>> 'Total with tax: ${0:.2f}'.format(13.00 * 1.0825) 
'Total with tax: $14.07' 
>>> d = {'web': 'user', 'page': 42} 
>>> 'http://xxx.yyy.zzz/{web}/{page}.html'.format(**d) 
'http://xxx.yyy.zzz/user/42.html'

Like Python 2.6+, all Python 3 releases (so far) understand how to do both. I shamelessly ripped this stuff straight out of my hardcore Python intro book and the slides for the Intro+Intermediate Python courses I offer from time-to-time. :-)

Aug 2018 UPDATE: Of course, now that we have the f-string feature in 3.6, we need the equivalent examples of that, yes another alternative:

>>> name, age = 'John', 35
>>> f'Name: {name}, age: {age}'
'Name: John, age: 35'

>>> i = 45
>>> f'dec: {i}/oct: {i:#o}/hex: {i:#X}'
'dec: 45/oct: 0o55/hex: 0X2D'

>>> m, d, y = 12, 7, 41
>>> f"MM/DD/YY = {m:02d}/{d:02d}/{y:02d}"
'MM/DD/YY = 12/07/41'

>>> f'Total with tax: ${13.00 * 1.0825:.2f}'
'Total with tax: $14.07'

>>> d = {'web': 'user', 'page': 42}
>>> f"http://xxx.yyy.zzz/{d['web']}/{d['page']}.html"
'http://xxx.yyy.zzz/user/42.html'

Use the StringFormat property (or ContentStringFormat on ContentControl and its derivatives, e.g. Label).

<TextBlock Text="{Binding Date, StringFormat={}{0:d}}" />

Note the {} prior to the standard String.Format positional argument notation allows the braces to be escaped in the markup extension language.

This whole setup seems a little unstable to me.

Talk to the ffmpegx folks about having a GUI front-end over a command-line backend. It doesn't seem to bother them.

Indeed, I submit that a GUI (or web) front-end over a command-line backend is actually more stable, since you have a very, very clean interface between GUI and command. The command can evolve at a different pace from the web, as long as the command-line options are compatible, you have no possibility of breakage.

My advise would be also to not ignore the .idea folder.

I've imported a Git-based Eclipse project to Android Studio and that went fine. Later, I wanted to import this project with Git (like the first time) to another machine with Android Studio, but that didn't worked. Android Studio did load all the files but wasn't able to "see" the project as a project. I only could open Git-files.

While importing the project for the first time (from Eclipse to Android Studio) my old .gitignore was overwritten and the new one looked like this:

• .idea/.name
• .idea/compiler.xml
• .idea/copyright/profiles_settings.xml
• .idea/encodings.xml
• .idea/libraries/libs.xml
• .idea/misc.xml
• .idea/modules.xml
• .idea/scopes/scope_settings.xml
• .idea/vcs.xml
• .idea/workspace.xml

So, I tried to use an empty gitignore and now it worked. The other Android Studio could load the files and the Project. I guess some files are not important (profiles_settings.xml) for Git and importing but I am just happy it worked.

In WSDL definition, bindings contain operations, here comes style for each operation.

Document : In WSDL file, it specifies types details either having inline Or imports XSD document, which describes the structure(i.e. schema) of the complex data types being exchanged by those service methods which makes loosely coupled. Document style is default.

• Advantage:
  • Using this Document style, we can validate SOAP messages against predefined schema. It supports xml datatypes and patterns.
  • loosely coupled.
• Disadvantage: It is a little bit hard to get understand.

In WSDL types element looks as follows:

<types>
 <xsd:schema>
  <xsd:import schemaLocation="http://localhost:9999/ws/hello?xsd=1" namespace="http://ws.peter.com/"/>
 </xsd:schema>
</types>

The schema is importing from external reference.

RPC :In WSDL file, it does not creates types schema, within message elements it defines name and type attributes which makes tightly coupled.

<types/>  
<message name="getHelloWorldAsString">  
<part name="arg0" type="xsd:string"/>  
</message>  
<message name="getHelloWorldAsStringResponse">  
<part name="return" type="xsd:string"/>  
</message>  

• Advantage: Easy to understand.
• Disadvantage:
  • we can not validate SOAP messages.
  • tightly coupled

RPC : No types in WSDL
Document: Types section would be available in WSDL

Your code works fine. When I ran it I got the output:

The values in the file input.txt are:
1
2
3
4
5
6
7
8
9
10
The sum of the values is: 55
The mean value is: 5.5

But it could still be improved.

You are iterating over the vector using indexes. This is not the "STL Way" -- you should be using iterators, to wit:

typedef vector<double> doubles;
for( doubles::const_iterator it = v.begin(), it_end = v.end(); it != it_end; ++it )
{
    total += *it;
    mean = total / v.size();
}

This is better for a number of reasons discussed here and elsewhere, but here are two main reasons:

1. Every container provides the iterator concept. Not every container provides random-access (eg, indexed access).
2. You can generalize your iteration code.

Point number 2 brings up another way you can improve your code. Another thing about your code that isn't very STL-ish is the use of a hand-written loop. <algorithm>s were designed for this purpose, and the best code is the code you never write. You can use a loop to compute the total and mean of the vector, through the use of an accumulator:

#include <numeric>
#include <functional>
struct my_totals : public std::binary_function<my_totals, double, my_totals>
{
    my_totals() : total_(0), count_(0) {};
    my_totals operator+(double v) const
    {
        my_totals ret = *this;
        ret.total_ += v;
        ++ret.count_;
        return ret;
    }
    double mean() const { return total_/count_; }
    double total_;
    unsigned count_;
};

...and then:

my_totals ttls = std::accumulate(v.begin(), v.end(), my_totals());
cout << "The sum of the values is: " << ttls.total_ << endl;
cout << "The mean value is: " << ttls.mean() << endl;

EDIT:

If you have the benefit of a C++0x-compliant compiler, this can be made even simpler using std::for_each (within #include <algorithm>) and a lambda expression:

double total = 0;
for_each( v.begin(), v.end(), [&total](double  v) { total += v; });
cout << "The sum of the values is: " << total << endl;
cout << "The mean value is: " << total/v.size() << endl;

Change return false; to return true; in longClickListener

You long click the button, if it returns true then it does the work. If it returns false then it does it's work and also calls the short click and then the onClick also works.

This is from comment by phihag above, deserves a separate answer. This works but info proc does not on the arm-none-eabi-gdb v7.4.1.20130913-cvs from the gcc-arm-none-eabi Ubuntu package.

I don't think you can get it directly, but there are a few ways to find it indirectly.

One way is to use the GC.GetTotalMemory method to measure the amount of memory used before and after creating your object. This won't be perfect, but as long as you control the rest of the application you may get the information you are interested in.

Apart from that you can use a profiler to get the information or you could use the profiling api to get the information in code. But that won't be easy to use I think.

See Find out how much memory is being used by an object in C#? for a similar question.

How about some extension methods that asynchronously await the completion of the asynchronous operation, then set a ManualResetEvent to indicate completion.

NOTE: You can use Task.Run(), however extension methods are a cleaner interface for expressing what you really want.

In case you need this to write a .properties file you can just add the Strings into a Properties object and then save it to a file. It will take care for the conversion.

The click handler that you are trying to trigger is most likely also attached via $(document).ready(). What is probably happening is that you are triggering the event before the handler is attached. The solution is to use setTimeout:

$("document").ready(function() {
    setTimeout(function() {
        $("ul.galleria li:first-child img").trigger('click');
    },10);
});

A delay of 10ms will cause the function to run immediately after all the $(document).ready() handlers have been called.

OR you check if the element is ready:

$("document").ready(function() {
  $("ul.galleria li:first-child img").ready(function() {
    $(this).click();
  });    
});

Basically, you need two jobs. One to check whether files changed and one to do the actual build:

Job #1

This should be triggered on changes in your Git repository. It then tests whether the path you specify ("src" here) has changes and then uses Jenkins' CLI to trigger a second job.

export JENKINS_CLI="java -jar /var/run/jenkins/war/WEB-INF/jenkins-cli.jar"
export JENKINS_URL=http://localhost:8080/
export GIT_REVISION=`git rev-parse HEAD`
export STATUSFILE=$WORKSPACE/status_$BUILD_ID.txt

# Figure out, whether "src" has changed in the last commit
git diff-tree --name-only HEAD | grep src

# Exit with success if it didn't
$? || exit 0

# Trigger second job
$JENKINS_CLI build job2 -p GIT_REVISION=$GIT_REVISION -s

Job #2

Configure this job to take a parameter GIT_REVISION like so, to make sure you're building exactly the revision the first job chose to build.

I've had to do this before using Paramiko in a case where I wanted to run a dynamic, local PyQt4 script on a host running an ssh server that has connected my OpenVPN server and ask for their routing preference (split tunneling).

So long as the ssh server you are connecting to has all of the required dependencies of your script (PyQt4 in my case), you can easily encapsulate the data by encoding it in base64 and use the exec() built-in function on the decoded message. If I remember correctly my one-liner for this was:

stdout = client.exec_command('python -c "exec(\\"' + open('hello.py','r').read().encode('base64').strip('\n') + '\\".decode(\\"base64\\"))"' )[1]

It is hard to read and you have to escape the escape sequences because they are interpreted twice (once by the sender and then again by the receiver). It also may need some debugging, I've packed up my server to PCS or I'd just reference my OpenVPN routing script.

The difference in doing it this way as opposed to sending a file is that it never touches the disk on the server and is run straight from memory (unless of course they log the command). You'll find that encapsulating information this way (although inefficient) can help you package data into a single file.

For instance, you can use this method to include raw data from external dependencies (i.e. an image) in your main script.

It will work if you use an IP or set domain to none. Details here:

http://analyticsimpact.com/2011/01/20/google-analytics-on-intranets-and-development-servers-fqdn/

The easiest way is to fire the debugger and check the disassembly window.

=(((A1/60)/60)/24)+DATE(1970,1,1)+(-5/24)

assuming A1 is the cell where your time stamp is located and dont forget to adjust to account for the time zone you are in (5 assuming you are on EST)

psql databasename < data_base_dump

That's the command you are looking for.

Beware: databasename must be created before importing. Have a look at the PostgreSQL Docs Chapter 23. Backup and Restore.

How about this:

from pandas import *

idx = Int64Index([171, 174, 173])
df = DataFrame(index = idx, data =([1,2,3]))
print df

It gives me:

     0
171  1
174  2
173  3

Is this what you are looking for?

All the highlighted solutions are using recursion (which is performance costly). Here is cleaner way without recursion:

public T GetControlByType<T>(Control root, Func<T, bool> predicate = null) where T : Control 
{
    if (root == null) {
        throw new ArgumentNullException("root");
    }

    var stack = new Stack<Control>(new Control[] { root });

    while (stack.Count > 0) {
        var control = stack.Pop();
        T match = control as T;

        if (match != null && (predicate == null || predicate(match))) {
            return match;
        }

        foreach (Control childControl in control.Controls) {
           stack.Push(childControl);
        }
    }

    return default(T);
}

After viewing and changed the properties to DocumentFormat.OpenXml, I also had to change the Specific Version to false.

You can also plot the timestamp, value pairs using pyplot.plot (after parsing them from their string representation). (Tested with matplotlib versions 1.2.0 and 1.3.1.)

Example:

import datetime
import random
import matplotlib.pyplot as plt

# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.plot(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()

plt.show()

Resulting image:

Here's the same as a scatter plot:

import datetime
import random
import matplotlib.pyplot as plt

# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.scatter(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()

plt.show()

Produces an image similar to this:

This works too and also demonstrates how to change the legend title:

ggplot(df, aes(x, y, colour=g)) +
  geom_line(stat="identity") + 
  theme(legend.position="bottom") +
  scale_color_discrete(name="")

you have to add the property Tables to the DataGridView Data Source

 dataGridView1.DataSource = table.Tables[0];

Step1

In your Dockerfile, you can use the verb EXPOSE to expose multiple ports.
e.g.

EXPOSE 3000 80 443 22

Step2

You then would like to build an new image based on above Dockerfile.
e.g.

docker build -t foo:tag .

Step3

Then you can use the -p to map host port with the container port, as defined in above EXPOSE of Dockerfile.
e.g.

docker run -p 3001:3000 -p 23:22

In case you would like to expose a range of continuous ports, you can run docker like this:

docker run -it -p 7100-7120:7100-7120/tcp 

There are multiple ways to open a link in new tab in using Selenium WebDriver.

Usecase A: Opening an adjacent blank tab and iterating through an iterator

• Code Block:

  import java.util.Iterator;
  import java.util.Set;
  
  import org.openqa.selenium.JavascriptExecutor;
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.chrome.ChromeDriver;
  import org.openqa.selenium.chrome.ChromeOptions;
  import org.openqa.selenium.support.ui.ExpectedConditions;
  import org.openqa.selenium.support.ui.WebDriverWait;
  
  public class NewTab_blank_iterator {
  
      public static void main(String[] args) {
  
          System.setProperty("webdriver.chrome.driver","C:\\WebDrivers\\chromedriver.exe");
          ChromeOptions options = new ChromeOptions();
          options.addArguments("start-maximized");
          WebDriver driver =  new ChromeDriver(options); 
          driver.get("https://mail.google.com/");
          String firstWindowHandle = driver.getWindowHandle();
          System.out.println("First Window Handle is: "+firstWindowHandle);
          // Opening an adjacent blank tab
          ((JavascriptExecutor)driver).executeScript("window.open('','_blank');");
          new WebDriverWait(driver, 10).until(ExpectedConditions.numberOfWindowsToBe(2));
          Set<String> allWindowHandles = driver.getWindowHandles();
          // Using iterator
          Iterator<String> itr = allWindowHandles.iterator();
          while(itr.hasNext()) {
              String nextWindow = itr.next();
              if(!firstWindowHandle.equalsIgnoreCase(nextWindow)) {
                  driver.switchTo().window(nextWindow);
                  System.out.println("New Tab Window Handle is: "+nextWindow);
              }
          }
      }
  }
  

• Console Output:

  First Window Handle is: CDwindow-0D89767363ED691767000F01E6712D0B
  New Tab Window Handle is: CDwindow-7232D2058514ED22344F129D30A0CCE7

Both definitions of modulus of negative numbers are in use - some languages use one definition and some the other.

If you want to get a negative number for negative inputs then you can use this:

int r = x % n;
if (r > 0 && x < 0)
{
    r -= n;
}

Likewise if you were using a language that returns a negative number on a negative input and you would prefer positive:

int r = x % n;
if (r < 0)
{
    r += n;
}

A shorter way to write the condition:

WHERE some_col > ''

Since null > '' produces unknown, this has the effect of filtering out both null and empty strings.

There is also some simple solution without mapping node_module directory into another volume. It's about to move installing npm packages into final CMD command.

Disadvantage of this approach:

• run npm install each time you run container (switching from npm to yarn might also speed up this process a bit).

In my situation, --prefix= failed to update the path correctly under some warnings or failures. please see the below link for the answer. https://stackoverflow.com/a/50208379/1283198

Only you need to add other parameter in your route, the parameter is useAsDefault:true. For example, if you want the DashboardComponent as default you need to do this:

@RouteConfig([
    { path: '/Dashboard', component: DashboardComponent , useAsDefault:true},
    .
    .
    .
    ])

I recomend you to add names to your routes.

{ path: '/Dashboard',name:'Dashboard', component: DashboardComponent , useAsDefault:true}

In Ef .net core there are two options that you can do; first with data annotations:

public class Blog
{
    public int BlogId { get; set; }
    [Required]
    public string Url { get; set; }
}

Or with fluent api:

class MyContext : DbContext
{
    public DbSet<Blog> Blogs { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Blog>()
            .Property(b => b.Url)
            .IsRequired(false)//optinal case
            .IsRequired()//required case
            ;
    }
}

public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }
}

It happens when common column in both table are of different data type.

Example: In table1, you have date as string whereas in table2 you have date as datetime. so before merging,we need to change date to common data type.

Using this source code you can upload multiple file like google one by one through ajax. Also you can see the uploading progress

HTML

 <input type="file" id="multiupload" name="uploadFiledd[]" multiple >
 <button type="button" id="upcvr" class="btn btn-primary">Start Upload</button>
 <div id="uploadsts"></div>

Javascript

    <script>

    function uploadajax(ttl,cl){

    var fileList = $('#multiupload').prop("files");
    $('#prog'+cl).removeClass('loading-prep').addClass('upload-image');

    var form_data =  "";

    form_data = new FormData();
    form_data.append("upload_image", fileList[cl]);


    var request = $.ajax({
              url: "upload.php",
              cache: false,
              contentType: false,
              processData: false,
              async: true,
              data: form_data,
              type: 'POST', 
              xhr: function() {  
                  var xhr = $.ajaxSettings.xhr();
                  if(xhr.upload){ 
                  xhr.upload.addEventListener('progress', function(event){
                      var percent = 0;
                      if (event.lengthComputable) {
                          percent = Math.ceil(event.loaded / event.total * 100);
                      }
                      $('#prog'+cl).text(percent+'%') 
                   }, false);
                 }
                 return xhr;
              },
              success: function (res, status) {
                  if (status == 'success') {
                      percent = 0;
                      $('#prog' + cl).text('');
                      $('#prog' + cl).text('--Success: ');
                      if (cl < ttl) {
                          uploadajax(ttl, cl + 1);
                      } else {
                          alert('Done');
                      }
                  }
              },
              fail: function (res) {
                  alert('Failed');
              }    
          })
    }

    $('#upcvr').click(function(){
        var fileList = $('#multiupload').prop("files");
        $('#uploadsts').html('');
        var i;
        for ( i = 0; i < fileList.length; i++) {
            $('#uploadsts').append('<p class="upload-page">'+fileList[i].name+'<span class="loading-prep" id="prog'+i+'"></span></p>');
            if(i == fileList.length-1){
                uploadajax(fileList.length-1,0);
            }
         }
    });
    </script>

PHP

upload.php
    move_uploaded_file($_FILES["upload_image"]["tmp_name"],$_FILES["upload_image"]["name"]);

This will clear only if you have filter and does not cause any error when there arent any filter. If ActiveSheet.AutoFilterMode Then ActiveSheet.Columns("A").AutoFilter

This worked for me. adding two dots and slash.

body{
    background: url(../images/yourimage.png);
}

You can get these data from RouteData of a ViewContext

ViewContext.RouteData.Values["controller"]
ViewContext.RouteData.Values["action"]

It's taking the ID , dividing it by 2 and checking if the remainder is not zero; meaning, it's an odd ID.

if(stop == true)

or

if(stop)

= is for assignment.

== is for checking condition.

if(stop = true) 

It will assign true to stop and evaluates if(true). So it will always execute the code inside if because stop will always being assigned with true.

I strongly recommend Perlbrew. It lets you run multiple versions of Perl, install packages, hack Perl internals if you want to, all regular user permissions.

You need to actually use the shortened array after you remove items from it. You are ignoring the shortened array.

You convert the cookie into an array. You reduce the length of the array and then you never use that shortened array. Instead, you just use the old cookie (the unshortened one).

You should convert the shortened array back to a string with .join(",") and then use it for the new cookie instead of using old_cookie which is not shortened.

You may also not be using .splice() correctly, but I don't know exactly what your objective is for shortening the array. You can read about the exact function of .splice() here.

I find this lecture very valuable https://vimeo.com/190275665, in point 3 it summarizes these generators and also gives some performance analysis and guideline one when you use each one.

This is a shorter version.

    return s.replace(/[$-\/?[-^{|}]/g, '\\$&');
}

This includes the non-meta characters of %, &, ', and ,, but the JavaScript RegExp specification allows this.

The first one is the "short" form - you use it, when you do not want to do something fancy with your getters and setters. It is not possible to execute a method or something like that in this form.

The second and third form are almost identical, albeit the second one is compressed to one line. This form is discouraged by stylecop because it looks somewhat weird and does not conform to C' Stylguides.

I would use the third form if I expectd to use my getters / setters for something special, e.g. use a lazy construct or so.

  String dateTime="15-3-2019 09:50 AM" //time should be two digit like 08,09,10 
   DateTimeFormatter dtf  = DateTimeFormatter.ofPattern("dd-MM-yyyy hh:mm a");
        LocalDateTime zdt  = LocalDateTime.parse(dateTime,dtf);
        LocalDateTime now = LocalDateTime.now();
        ZoneId zone = ZoneId.of("Asia/Kolkata");
        ZoneOffset zoneOffSet = zone.getRules().getOffset(now);
        long a= zdt.toInstant(zoneOffSet).toEpochMilli();
        Log.d("time","---"+a);

you can get zone id form this a link!

tar cf - $PWD|tar tvf -             

This is slow but works recursively and prints both directories and files. You can pipe it with awk/grep if you just want the file names without all the other info/directories:

tar cf - $PWD|tar tvf -|awk '{print $6}'|grep -v "/$"          

One-liner:

for F in K*; do NEWNAME=$(echo "$F" | tr '[:upper:]' '[:lower:]'); mv "$F" "$NEWNAME"; done

Note that this will convert only files/directories starting with letter K, so adjust accordingly.

The DFS-based variants with back edges will find cycles indeed, but in many cases it will NOT be minimal cycles. In general DFS gives you the flag that there is a cycle but it is not good enough to actually find cycles. For example, imagine 5 different cycles sharing two edges. There is no simple way to identify cycles using just DFS (including backtracking variants).

Johnson's algorithm is indeed gives all unique simple cycles and has good time and space complexity.

But if you want to just find MINIMAL cycles (meaning that there may be more then one cycle going through any vertex and we are interested in finding minimal ones) AND your graph is not very large, you can try to use the simple method below. It is VERY simple but rather slow compared to Johnson's.

So, one of the absolutely easiest way to find MINIMAL cycles is to use Floyd's algorithm to find minimal paths between all the vertices using adjacency matrix. This algorithm is nowhere near as optimal as Johnson's, but it is so simple and its inner loop is so tight that for smaller graphs (<=50-100 nodes) it absolutely makes sense to use it. Time complexity is O(n^3), space complexity O(n^2) if you use parent tracking and O(1) if you don't. First of all let's find the answer to the question if there is a cycle. The algorithm is dead-simple. Below is snippet in Scala.

  val NO_EDGE = Integer.MAX_VALUE / 2

  def shortestPath(weights: Array[Array[Int]]) = {
    for (k <- weights.indices;
         i <- weights.indices;
         j <- weights.indices) {
      val throughK = weights(i)(k) + weights(k)(j)
      if (throughK < weights(i)(j)) {
        weights(i)(j) = throughK
      }
    }
  }

Originally this algorithm operates on weighted-edge graph to find all shortest paths between all pairs of nodes (hence the weights argument). For it to work correctly you need to provide 1 if there is a directed edge between the nodes or NO_EDGE otherwise. After algorithm executes, you can check the main diagonal, if there are values less then NO_EDGE than this node participates in a cycle of length equal to the value. Every other node of the same cycle will have the same value (on the main diagonal).

To reconstruct the cycle itself we need to use slightly modified version of algorithm with parent tracking.

  def shortestPath(weights: Array[Array[Int]], parents: Array[Array[Int]]) = {
    for (k <- weights.indices;
         i <- weights.indices;
         j <- weights.indices) {
      val throughK = weights(i)(k) + weights(k)(j)
      if (throughK < weights(i)(j)) {
        parents(i)(j) = k
        weights(i)(j) = throughK
      }
    }
  }

Parents matrix initially should contain source vertex index in an edge cell if there is an edge between the vertices and -1 otherwise. After function returns, for each edge you will have reference to the parent node in the shortest path tree. And then it's easy to recover actual cycles.

All in all we have the following program to find all minimal cycles

  val NO_EDGE = Integer.MAX_VALUE / 2;

  def shortestPathWithParentTracking(
         weights: Array[Array[Int]],
         parents: Array[Array[Int]]) = {
    for (k <- weights.indices;
         i <- weights.indices;
         j <- weights.indices) {
      val throughK = weights(i)(k) + weights(k)(j)
      if (throughK < weights(i)(j)) {
        parents(i)(j) = parents(i)(k)
        weights(i)(j) = throughK
      }
    }
  }

  def recoverCycles(
         cycleNodes: Seq[Int], 
         parents: Array[Array[Int]]): Set[Seq[Int]] = {
    val res = new mutable.HashSet[Seq[Int]]()
    for (node <- cycleNodes) {
      var cycle = new mutable.ArrayBuffer[Int]()
      cycle += node
      var other = parents(node)(node)
      do {
        cycle += other
        other = parents(other)(node)
      } while(other != node)
      res += cycle.sorted
    }
    res.toSet
  }

and a small main method just to test the result

  def main(args: Array[String]): Unit = {
    val n = 3
    val weights = Array(Array(NO_EDGE, 1, NO_EDGE), Array(NO_EDGE, NO_EDGE, 1), Array(1, NO_EDGE, NO_EDGE))
    val parents = Array(Array(-1, 1, -1), Array(-1, -1, 2), Array(0, -1, -1))
    shortestPathWithParentTracking(weights, parents)
    val cycleNodes = parents.indices.filter(i => parents(i)(i) < NO_EDGE)
    val cycles: Set[Seq[Int]] = recoverCycles(cycleNodes, parents)
    println("The following minimal cycle found:")
    cycles.foreach(c => println(c.mkString))
    println(s"Total: ${cycles.size} cycle found")
  }

and the output is

The following minimal cycle found:
012
Total: 1 cycle found

I searched for multiple options to get my git reset to specific commit, but most of them aren't so satisfactory.

I generally use this to reset the git to the specific commit in source tree.

1. select commit to reset on sourcetree.

2. In dropdowns select the active branch , first Parent Only

3. And right click on "Reset branch to this commit" and select hard reset option (soft, mixed and hard)

4. and then go to terminal git push -f

You should be all set!

You can delete the index by Kibana Console:

To get all index:

GET /_cat/indices?v

To delete a specific index:

DELETE /INDEX_NAME_TO_DELETE

I've been trying different variants of this for days, and I thought for a day I had it re-launching the app in the background, even when the user swiped to kill, but no I can't replicate that behavior.

It's unfortunate that the behavior is quite different than before. On iOS 6, if you killed the app from the jiggling icons, it would still get re-awoken on SLC triggers. Now, if you kill by swiping, that doesn't happen.

It's a different behavior, and the user, who would continue to get useful information from our app if they had killed it on iOS 6, now will not.

We need to nudge our users to re-open the app now if they have swiped to kill it and are still expecting some of the notification behavior that we used to give them. I'm worried this won't be obvious to users when they swipe an app away. They may, after all, be basically cleaning up or wanting to rearrange the apps that are shown minimized.

I had this problem. As stated it is probably a static declaration issue. In my case it was because I had a static within a DEBUG clause. That is (in c#)

#if DEBUG
    public static bool DOTHISISINDEBUGONLY = false;
#endif

Everything worked fine until I complied a Release version of the code and after that I got this error - even on old release versions of the code. Once I took the variable out of the DEBUG clause everything returned to normal.

delete foo[key];

:D

Here is a solution that may help with this strange behaviour. I couldn't find a better solution than place a button to manually trigger the change event.

EDIT: Maybe a custom binding like this could help:

ko.bindingHandlers.changeSelectValue = {

   init: function(element,valueAccessor){

        $(element).change(function(){

            var value = $(element).val();

            if($(element).is(":focus")){

                  //Do whatever you want with the new value
            }

        });

    }
  };

And in your select data-bind attribute add:

changeSelectValue: yourSelectValue

A one liner:

perl -pi.back -e 's/<PREF>/ABCD/g;' inputfile

You can write directly to the response but then it isn't testable. It is preferred to return an ActionResult that has deferred execution. Here is my resusable StreamResult:

public class StreamResult : ViewResult
{
    public Stream Stream { get; set; }
    public string ContentType { get; set; }
    public string ETag { get; set; }

    public override void ExecuteResult(ControllerContext context)
    {
        context.HttpContext.Response.ContentType = ContentType;
        if (ETag != null) context.HttpContext.Response.AddHeader("ETag", ETag);
        const int size = 4096;
        byte[] bytes = new byte[size];
        int numBytes;
        while ((numBytes = Stream.Read(bytes, 0, size)) > 0)
            context.HttpContext.Response.OutputStream.Write(bytes, 0, numBytes);
    }
}

Creating an App Inventor app begins in your browser, where you design how the app will look. Then, like fitting together puzzle pieces, you set your app's behavior. All the while, through a live connection between your computer and your phone, your app appears on your phone.

I was also facing the same issue, tried all the solutions mentioned in the answer but none seemed to work. Turned out that during the checkin of code to TFS. TFS did not checkin the Resx file it only checked in the designer file. So all other developers were facing this issue while running on their machines. Checking in the resx file manually did the trick

• Press Esc to enter 'command mode'
• Use Ctrl+V to enter visual block mode
• Move Up/Downto select the columns of text in the lines you want to comment.
• Then hit Shift+i and type the text you want to insert.
• Then hit Esc, wait 1 second and the inserted text will appear on every line.

For further information and reading, check out "Inserting text in multiple lines" in the Vim Tips Wiki.

@Query("select b.equipSealRegisterId from EquipSealRegister b where b.sealName like %?1% and b.deleteFlag = '0'" )
    List<String>findBySeal(String sealname);

I have tried this code and it works.

An easy way is :

        wstring your_wchar_in_ws(<your wchar>);
        string your_wchar_in_str(your_wchar_in_ws.begin(), your_wchar_in_ws.end());
        char* your_wchar_in_char =  your_wchar_in_str.c_str();

I'm using this method for years :)

Here is some hacketi hack code. I wanted to maintain a row template in an HTML page. Table rows 0...n are rendered at request time, and this example has one hardcoded row and a simplified template row. The template table is hidden, and the row tag must be within a valid table or browsers may drop it from the DOM tree. Adding a row uses counter+1 identifier, and the current value is maintained in the data attribute. It guarantees each row gets unique URL parameters.

I have run tests on Internet Explorer 8, Internet Explorer 9, Firefox, Chrome, Opera, Nokia Lumia 800, Nokia C7 (with Symbian 3), Android stock and Firefox beta browsers.

PS: I give all credits to the jQuery team; they deserve everything. JavaScript programming without jQuery - I don't even want think about that nightmare.

You have to select and send the form data as well:

$("#post-btn").click(function(){        
    $.post("process.php", $("#reg-form").serialize(), function(data) {
        alert(data);
    });
});

Take a look at the documentation for the jQuery serialize method, which encodes the data from the form fields into a data-string to be sent to the server.

Answer in Swift 5 (Continuation of Ricky's answer in Swift)

Add the UIGestureRecognizerDelegate to your ViewController

 override func viewDidLoad() {
    super.viewDidLoad()

    //Long Press
    let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress))
    longPressGesture.minimumPressDuration = 0.5
    self.tableView.addGestureRecognizer(longPressGesture)
 }

And the function:

@objc func handleLongPress(longPressGesture: UILongPressGestureRecognizer) {
    let p = longPressGesture.location(in: self.tableView)
    let indexPath = self.tableView.indexPathForRow(at: p)
    if indexPath == nil {
        print("Long press on table view, not row.")
    } else if longPressGesture.state == UIGestureRecognizer.State.began {
        print("Long press on row, at \(indexPath!.row)")
    }
}

I can tell you something:

Snippet #1 is not acceptable because it's ignoring exception. (it's swallowing it like nothing happened).

So do not add catch block that do nothing or just rethrows.

Catch block should add some value. For example output message to end user or log error.

Do not use exception for normal flow program logic. For example:

e.g input validation. <- This is not valid exceptional situation, rather you should write method IsValid(myInput); to check whether input item is valid or not.

Design code to avoid exception. For example:

int Parse(string input);

If we pass value that cannot be parsed to int, this method would throw and exception, instead of that we might write something like this:

bool TryParse(string input,out int result); <- this method would return boolean indicating if parse was successfull.

Maybe this is little bit out of scope of this question, but I hope this will help you to make right decisions when it's about try {} catch(){} and exceptions.

the answer with the host name didn't work for me but this did :

git clone file:////home/git/repositories/MyProject.git/

INSERTED and DELETED are virtual tables. They need to be used in a FROM clause.

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    IF EXISTS (SELECT foo
               FROM database2.dbo.table2
               WHERE id IN (SELECT deleted.id FROM deleted)
               AND bar = 4)

According to the official documentation:

Fragment#setTargetFragment

Optional target for this fragment. This may be used, for example, if this fragment is being started by another, and when done wants to give a result back to the first. The target set here is retained across instances via FragmentManager#putFragment.

Fragment#getTargetFragment

Return the target fragment set by setTargetFragment(Fragment, int).

So you can do this:

// In your fragment

public class MyFragment extends Fragment implements OnClickListener {
    private void showDialog() {
        DialogFragment dialogFrag = MyDialogFragment.newInstance(this);
        // Add this
        dialogFrag.setTargetFragment(this, 0);
        dialogFrag.show(getFragmentManager, null);
    }
    ...
}

// then

public class MyialogFragment extends DialogFragment {
    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        // Then get it
        Fragment fragment = getTargetFragment();
        if (fragment instanceof OnClickListener) {
            listener = (OnClickListener) fragment;
        } else {
            throw new RuntimeException("you must implement OnClickListener");
        }
    }
    ...
}

statmodels graphics also gives a nice view of correlation matrix

import statsmodels.api as sm
import matplotlib.pyplot as plt

corr = dataframe.corr()
sm.graphics.plot_corr(corr, xnames=list(corr.columns))
plt.show()

Just to add another flavor from the Reuben response, I use it like this to add or remove this rule according to a condition:

    RelativeLayout.LayoutParams layoutParams =
            (RelativeLayout.LayoutParams) holder.txtGuestName.getLayoutParams();

    if (SOMETHING_THAT_WOULD_LIKE_YOU_TO_CHECK) {
        // if true center text:
        layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);
        holder.txtGuestName.setLayoutParams(layoutParams);
    } else {
        // if false remove center:
        layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, 0);
        holder.txtGuestName.setLayoutParams(layoutParams);
    }

You are correct that this is currently not natively supported in Android, although Google has been saying it will be coming ever since Android was officially launched.

While not natively supported, the hardware on every android device released to date do support it. It is just disabled in software, and you would need to enable it in order to use these features.

It is however, fairly easy to do this, but you need to be root, and the specifics may be slightly different between different devices. Your best source for more informationa about this, would be XDA developers: http://forum.xda-developers.com/forumdisplay.php?f=564. Most of the existing solutions are based on replacing wpa_supplicant, and is the method I would recommend if possible on your device. For more details, see http://szym.net/2010/12/adhoc-wifi-in-android/.

Update: Its been a few years now, and whenever I need an ad hoc network connection on my phone I use CyanogenMod. It gives you both programmatic and scripted access to these functions, and the ability to create ad hoc (ibss) networks in the WiFi settings menu.

I have slightly modified the jangorecki function for the case where we may have a variety of values that cannot be converted to a number. In my function, a template search is performed and if the template is not found, FALSE is returned.! before gperl, it means that we need those vector elements that do not match the template. The rest is similar to the as.num function. Example:

as.num.pattern <- function(x, pattern){
  stopifnot(is.character(x))
  na = !grepl(pattern, x)
  x[na] = -Inf
  x = as.numeric(x)
  x[na] = NA_real_
  x
}

as.num.pattern(c('1', '2', '3.43', 'char1', 'test2', 'other3', '23/40', '23, 54 cm.'))

[1] 1.00 2.00 3.43   NA   NA   NA   NA   NA

To remove & delete all changes git clean -d -f

Environment returns user data directory. And getFilesDir returns application data directory.

import matplotlib.pyplot as plt

You can also run once in your code

plt.gray()

This will show the images in grayscale as default

im = array(Image.open('I_am_batman.jpg').convert('L'))
plt.imshow(im)
plt.show()

DATA = { u'spam': u'eggs', u'foo': frozenset([u'Gah!']), u'bar': { u'baz': 97 },
         u'list': [u'list', (True, u'Maybe'), set([u'and', u'a', u'set', 1])]}

def convert(data):
    if isinstance(data, basestring):
        return str(data)
    elif isinstance(data, collections.Mapping):
        return dict(map(convert, data.iteritems()))
    elif isinstance(data, collections.Iterable):
        return type(data)(map(convert, data))
    else:
        return data

print DATA
print convert(DATA)
# Prints:
# {u'list': [u'list', (True, u'Maybe'), set([u'and', u'a', u'set', 1])], u'foo': frozenset([u'Gah!']), u'bar': {u'baz': 97}, u'spam': u'eggs'}
# {'bar': {'baz': 97}, 'foo': frozenset(['Gah!']), 'list': ['list', (True, 'Maybe'), set(['and', 'a', 'set', 1])], 'spam': 'eggs'}

Assumptions:

• You've imported the collections module and can make use of the abstract base classes it provides
• You're happy to convert using the default encoding (use data.encode('utf-8') rather than str(data) if you need an explicit encoding).

If you need to support other container types, hopefully it's obvious how to follow the pattern and add cases for them.

The accepted solution didn't work for me but I did some digging on the project settings.

The following solution fixed it for me at least IF you are using a Dynamic Web Project:

1. Right click on the project then properties. (or alt-enter on the project)
2. Under Deployment Assembly remove "src".

You should be able to add the src/main/java. It also automatically adds it to Deployment Assembly.

Caveat: If you added a src/test/java note that it also adds it to Deployment Assembly. Generally, you don't need this. You may remove it.

Your system does not have a GUI manager. Happens mostly in Solaris/Linux boxes. If you are using GUI in them make sure that you have a GUI manager installed and you may also want to google through the DISPLAY variable.

Try this:

<?php
$to = "[email protected]";
$subject = "My subject";
$txt = "Hello world!";
$headers = "From: [email protected]" . "\r\n" .
"CC: [email protected]";

mail($to,$subject,$txt,$headers);
?>

I think the most intuitive way to do this is by giving the children a "wait" prop, which hides the component for the duration that was passed down from the parent. By setting the default state to hidden, React will still render the component immediately, but it won't be visible until the state has changed. Then, you can set up componentWillMount to call a function to show it after the duration that was passed via props.

var Child = React.createClass({
    getInitialState : function () {
        return({hidden : "hidden"});
    },
    componentWillMount : function () {
        var that = this;
        setTimeout(function() {
            that.show();
        }, that.props.wait);
    },
    show : function () {
        this.setState({hidden : ""});
    },
    render : function () {
        return (
            <div className={this.state.hidden}>
                <p>Child</p>
            </div>
        )
    }
});

Then, in the Parent component, all you would need to do is pass the duration you want a Child to wait before displaying it.

var Parent = React.createClass({
    render : function () {
        return (
            <div className="parent">
                <p>Parent</p>
                <div className="child-list">
                    <Child wait={1000} />
                    <Child wait={3000} />
                    <Child wait={5000} />
                </div>
            </div>
        )
    }
});

Here's a demo

a = (b = 'string is truthy'); // b gets string; a gets b, which is a primitive (copy)
a = (b = { c: 'yes' }); // they point to the same object; a === b (not a copy)

(a && b) is logically (a ? b : a) and behaves like multiplication (eg. !!a * !!b)

(a || b) is logically (a ? a : b) and behaves like addition (eg. !!a + !!b)

(a = 0, b) is short for not caring if a is truthy, implicitly return b

a = (b = 0) && "nope, but a is 0 and b is 0"; // b is falsey + order of operations
a = (b = "b is this string") && "a gets this string"; // b is truthy + order of ops

JavaScript Operator Precedence (Order of Operations)

Note that the comma operator is actually the least privileged operator, but parenthesis are the most privileged, and they go hand-in-hand when constructing one-line expressions.

Eventually, you may need 'thunks' rather than hardcoded values, and to me, a thunk is both the function and the resultant value (the same 'thing').

const windowInnerHeight = () => 0.8 * window.innerHeight; // a thunk

windowInnerHeight(); // a thunk

I had the same problem when I used code-first migrations to build my database for an MVC 5 application. I eventually found the seed method in my configuration.cs file to be causing the issue. My seed method was creating a table entry for the table containing the foreign key before creating the entry with the matching primary key.

For Angular 9+ You can add headers and params directly without the key-value notion:

const headers = new HttpHeaders().append('header', 'value');
const params = new HttpParams().append('param', 'value');
this.http.get('url', {headers, params}); 

I have solved this problem, please just make few changes

1- all controller class name should start with capital letter. i mean first letter of class should be capital . eg we have controler with class name Pages

so it should be Pages not pages

2- save the controller class Pages as Pages.php not pages.php

so first letter must be capital

same for model, model class first letter should be capital and also save model class as Pages_model.php not page_model.php

hope this will solve ur problem

you need to provide app name here like myapp

pm2 start npm --name {appName} -- run {script name}

you can check it by

pm2 list

you can also add time

pm2 restart "id" --log-date-format 'DD-MM HH:mm:ss.SSS' or pm2 restart "id" --time

you can check logs by

pm2 log "id" or pm2 log "appName"

to get logs for all app

pm2 logs

If the two databases are on the same server, you should be able to create a SQL statement something like this:

UPDATE Test1.dbo.Employee
SET DeptID = emp2.DeptID
FROM Test2.dbo.Employee as 'emp2'
WHERE
   Test1.dbo.Employee.EmployeeID = emp2.EmployeeID

From your post, I'm not quite clear whether you want to update Test1.dbo.Employee with the values from Test2.dbo.Employee (that's what my query does), or the other way around (since you mention the db on Test1 was the new table......)

See here:

http://jaanus.com/blog/2012/02/12/debugging-http-on-an-android-phone-or-tablet-with-charles-proxy-for-fun-and-profit/

You would need to install the charles.crt certificate to your device.

According to Ruskins answer and the comments here I came up with the following (recursive) solution:

public static T GetParentOfType<T>(this Control control) where T : class
{
    if (control?.Parent == null)
        return null;

    if (control.Parent is T parent)
        return parent;

    return GetParentOfType<T>(control.Parent);
}

@Daniel Thompson mentions that he had forgotten to add {"Content-Type": "application/json"} in the request. He was able to change the request, however, changing requests is not always possible (we are working on the server here).

In my case I needed to force content-type: text/plain to be parsed as json.

If you cannot change the content-type of the request, try using the following code:

app.use(express.json({type: '*/*'}));

Instead of using express.json() globally, I prefer to apply it only where needed, for instance in a POST request:

app.post('/mypost', express.json({type: '*/*'}), (req, res) => {
  // echo json
  res.json(req.body);
});

dic = {'female':1, 'male':0}
w['female'] = w['female'].replace(dic)

.replace has as argument a dictionary in which you may change and do whatever you want or need.

printf("%05d", zipCode);

The 0 indicates what you are padding with and the 5 shows the width of the integer number.

Example 1: If you use "%02d" (useful for dates) this would only pad zeros for numbers in the ones column. E.g., 06 instead of 6.

Example 2: "%03d" would pad 2 zeros for one number in the ones column and pad 1 zero for a number in the tens column. E.g., number 7 padded to 007 and number 17 padded to 017.

Here is a code to get the child elements (In java):

String childTag = childElement.getTagName();
if(childTag.equals("html")) 
{
    return "/html[1]"+current;
}
WebElement parentElement = childElement.findElement(By.xpath("..")); 
List<WebElement> childrenElements = parentElement.findElements(By.xpath("*"));
int count = 0;
for(int i=0;i<childrenElements.size(); i++) 
{
    WebElement childrenElement = childrenElements.get(i);
    String childrenElementTag = childrenElement.getTagName();
    if(childTag.equals(childrenElementTag)) 
    {
        count++;
    }
 }

In order to not have the Cannot recover key exception, I had to apply the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files to the installation of Java that was running my application. Version 8 of those files can be found here or the latest version should be listed on this page. The download includes a file that explains how to apply the policy files.

Since JDK 8u151 it isn't necessary to add policy files. Instead the JCE jurisdiction policy files are controlled by a Security property called crypto.policy. Setting that to unlimited with allow unlimited cryptography to be used by the JDK. As the release notes linked to above state, it can be set by Security.setProperty() or via the java.security file. The java.security file could also be appended to by adding -Djava.security.properties=my_security.properties to the command to start the program as detailed here.

Since JDK 8u161 unlimited cryptography is enabled by default.

To extend vlad2135's answer (read his first); that is how you set up Python debugging in Visual Studio Code with Don Jayamanne's great Python extension (which is a pretty full featured IDE for Python these days, and arguably one of Visual Studio Code's best language extensions, IMO).

Basically, when you click the gear icon, it creates a launch.json file in your .vscode directory in your workspace. You can also make this yourself, but it's probably just simpler to let Visual Studio Code do the heavy lifting. Here's an example file:

You'll notice something cool after you generate it. It automatically created a bunch of configurations (most of mine are cut off; just scroll to see them all) with different settings and extra features for different libraries or environments (like Django).

The one you'll probably end up using the most is Python; which is a plain (in my case C)Python debugger and is easiest to work with settings wise.

I'll make a short walkthrough of the JSON attributes for this one, since the others use the pretty much same configuration with only different interpreter paths and one or two different other features there.

• name: The name of the configuration. A useful example of why you would change it is if you have two Python configurations which use the same type of config, but different arguments. It's what shows up in the box you see on the top left (my box says "python" since I'm using the default Python configuration).
• type: Interpreter type. You generally don't want to change this one.
• request: How you want to run your code, and you generally don't want to change this one either. Default value is "launch", but changing it to "attach" allows the debugger to attach to an already running Python process. Instead of changing it, add a configuration of type attach and use that.
• stopOnEntry: Python debuggers like to have an invisible break-point when you start the program so you can see the entry-point file and where your first line of active code is. It drives some C#/Java programmers like me insane. false if you don't want it, true otherwise.
• pythonPath: The path to your install of Python. The default value gets the extension level default in the user/workspace settings. Change it here if you want to have different Pythons for different debug processes. Change it in workspace settings if you want to change it for all debug processes set to the default configuration in a project. Change it in user setting to change where the extension finds Pythons across all projects. (4/12/2017 The following was fixed in extension version 0.6.1). Ironically enough, this gets auto-generated wrong. It auto-generates to "${config.python.pythonPath}" which is deprecated in the newer Visual Studio Code versions. It might still work, but you should use "${config:python.pythonPath}" instead for your default first python on your path or Visual Studio Code settings. (4/6/2017 Edit: This should be fixed in the next release. The team committed the fix a few days ago.)
• program: The initial file that you debugger starts up when you hit run. "${workspaceRoot}" is the root folder you opened up as your workspace (When you go over to the file icon, the base open folder). Another neat trick if you want to get your program running quickly, or you have multiple entry points to your program is to set this to "${file}" which will start debugging at the file you have open and in focus in the moment you hit debug.
• cwd: The current working directory folder of the project you're running. Usually you'll just want to leave this "${workspaceRoot}".
• debugOptions: Some debugger flags. The ones in the picture are default flags, you can find more flags in the python debugger pages, I'm sure.
• args: This isn't actually a default configuration setting, but a useful one nonetheless (and probably what the OP was asking about). These are the command line arguments that you pass in to your program. The debugger passes these in as though they you had typed: python file.py [args] into your terminal; passing each JSON string in the list to the program in order.

You can go here for more information on the Visual Studio Code file variables you can use to configure your debuggers and paths.

You can go here for the extension's own documentation on launch options, with both optional and required attributes.

You can click the Add Configuration button at the bottom right if you don't see the config template already in the file. It'll give you a list to auto generate a configuration for most of the common debug processes out there.

Now, as per vlad's answer, you may add any breakpoints you need as per normal visual debuggers, choose which run configuration you want in the top left dropdown menu and you can tap the green arrow to the left to the configuration name to start your program.

Pro tip: Different people on your team use different IDEs and they probably don't need your configuration files. Visual Studio Code nearly always puts it's IDE files in one place (by design for this purpose; I assume), launch or otherwise so make sure to add directory .vscode/ to your .gitignore if this is your first time generating a Visual Studio Code file (this process will create the folder in your workspace if you don't have it already)!

Vue by default ships with the v-html directive to show it, you bind it onto the element itself rather than using the normal moustache binding for string variables.

So for your specific example you would need:

<div id="logapp">    
    <table>
        <tbody>
            <tr v-repeat="logs">
                <td v-html="fail"></td>
                <td v-html="type"></td>
                <td v-html="description"></td>
                <td v-html="stamp"></td>
                <td v-html="id"></td>
            </tr>
        </tbody>
    </table>
</div>

as @Christoph Winkler mentioned this is a base class for achieving it:

curl_helper.php

// This class has all the necessary code for making API calls thru curl library

class CurlHelper {

// This method will perform an action/method thru HTTP/API calls
// Parameter description:
// Method= POST, PUT, GET etc
// Data= array("param" => "value") ==> index.php?param=value
public static function perform_http_request($method, $url, $data = false)
{
    $curl = curl_init();

    switch ($method)
    {
        case "POST":
            curl_setopt($curl, CURLOPT_POST, 1);

            if ($data)
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            break;
        case "PUT":
            curl_setopt($curl, CURLOPT_PUT, 1);
            break;
        default:
            if ($data)
                $url = sprintf("%s?%s", $url, http_build_query($data));
    }

    // Optional Authentication:
    //curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    //curl_setopt($curl, CURLOPT_USERPWD, "username:password");

    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

    $result = curl_exec($curl);

    curl_close($curl);

    return $result;
}

}

Then you can always include the file and use it e.g.: any.php

    require_once("curl_helper.php");
    ...
    $action = "GET";
    $url = "api.server.com/model"
    echo "Trying to reach ...";
    echo $url;
    $parameters = array("param" => "value");
    $result = CurlHelper::perform_http_request($action, $url, $parameters);
    echo print_r($result)

Add a <div> wrapper around the table, and apply the following CSS

border-radius: x px;
overflow: hidden;
display: inline-block;

to this wrapper.

Have you looked into ControlsFx Popover control.

import org.controlsfx.control.PopOver;
import org.controlsfx.control.PopOver.ArrowLocation;

private PopOver item;

final Scene scene = addItemButton.getScene();

final Point2D windowCoord = new Point2D(scene.getWindow()
        .getX(), scene.getWindow().getY());

final Point2D sceneCoord = new Point2D(scene.getX(), scene.
                getY());

final Point2D nodeCoord = addItemButton.localToScene(0.0,
                        0.0);
final double clickX = Math.round(windowCoord.getX()
    + sceneCoord.getY() + nodeCoord.getX());

final double clickY = Math.round(windowCoord.getY()
        + sceneCoord.getY() + nodeCoord.getY());
item.setContentNode(addItemScreen);
item.setArrowLocation(ArrowLocation.BOTTOM_LEFT);
item.setCornerRadius(4);                            
item.setDetachedTitle("Add New Item");
item.show(addItemButton.getParent(), clickX, clickY);

This is only an example but a PopOver sounds like it could accomplish what you want. Check out the documentation for more info.

Important note: ControlsFX will only work on JavaFX 8.0 b118 or later.

Weak entities are also called dependent entities, since it's existence depends on other entities. Such entities are represented by a double outline rectangle in the E-R diagram.

Strong entities are also called independent entities.
