result = initial number + (6 - initial number % 6)

@recursive's solusion (The accepted answer) is 100% right. I am just adding a sample code for your reference.

My case is to display price with two decimal digits.This is part of back-end response: "price": 2300, "currencySymbol": "CD", ....

This is my helper class:

public class CurrencyUtils
{
    private static final String[] suffix = { "", "K", "M" };

    public static String getCompactStringForDisplay(final int amount)
    {
        int suffixIndex;
        if (amount >= 1_000_000) {
            suffixIndex = 2;
        } else if (amount >= 1_000) {
            suffixIndex = 1;
        } else {
            suffixIndex = 0;
        }

        int quotient;
        int remainder;
        if (amount >= 1_000_000) {
            quotient = amount / 1_000_000;
            remainder = amount % 1_000_000;
        } else if (amount >= 1_000) {
            quotient = amount / 1_000;
            remainder = amount % 1_000;
        } else {
            return String.valueOf(amount);
        }

        if (remainder == 0) {
            return String.valueOf(quotient) + suffix[suffixIndex];
        }

        // Keep two most significant digits
        if (remainder >= 10_000) {
            remainder /= 10_000;
        } else if (remainder >= 1_000) {
            remainder /= 1_000;
        } else if (remainder >= 100) {
            remainder /= 10;
        }

        return String.valueOf(quotient) + '.' + String.valueOf(remainder) + suffix[suffixIndex];
    }
}

This is my test class (based on Junit 4):

public class CurrencyUtilsTest {

    @Test
    public void getCompactStringForDisplay() throws Exception {
        int[] numbers = {0, 5, 999, 1_000, 5_821, 10_500, 101_800, 2_000_000, 7_800_000, 92_150_000, 123_200_000, 9_999_999};
        String[] expected = {"0", "5", "999", "1K", "5.82K", "10.50K", "101.80K", "2M", "7.80M", "92.15M", "123.20M", "9.99M"};

        for (int i = 0; i < numbers.length; i++) {
            int n = numbers[i];
            String formatted = CurrencyUtils.getCompactStringForDisplay(n);
            System.out.println(n + " => " + formatted);

            assertEquals(expected[i], formatted);
        }
    }

}

This code appears to do what you are asking for.

for value in range(1,1000):
    if value % 3 == 0 or value % 5 == 0:
        print(value)

Or something like

for value in range(1,1000):
    if value % 3 == 0 or value % 5 == 0:
        some_list.append(value)

Or any number of things.

Basically modulus Operator gives you remainder simple Example in maths what's left over/remainder of 11 divided by 3? answer is 2

for same thing C++ has modulus operator ('%')

Basic code for explanation

#include <iostream>
using namespace std;


int main()
{
    int num = 11;
    cout << "remainder is " << (num % 3) << endl;

    return 0;
}

Which will display

remainder is 2

Note: Disregard this answer, as I must have misunderstood the question.

select *
  from Table
  where len(ColName) mod 2 = 1

The exact syntax depends on what flavor of SQL you're using.

Modulus operator gives you the result in 'reduced residue system'. For example for mod 5 there are 5 integers counted: 0,1,2,3,4. In fact 19=12=5=-2=-9 (mod 7). The main difference that the answer is given by programming languages by 'reduced residue system'.

You probably had a typo when you first ran it.

evaluating 0.5 % 0.3 returns '0.2' (A double) as expected.

Mindprod has a good overview of how modulus works in Java.

you can use the google chart api and generate any color with rgb code on the fly:

example: marker with #ddd color:

http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|ddd

include as stated above with

 var marker = new google.maps.Marker({
    position: marker,
    title: 'Hello World',
    icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|ddd'
});

Just found out that with the Java NIO (java.nio.file.*) you can easily write:

List<String> lines=Files.readAllLines(Paths.get("/tmp/test.csv"), StandardCharsets.UTF_8);
for(String line:lines){
  System.out.println(line);
}

instead of dealing with FileInputStreams and BufferedReaders...

If you're using maven, perhaps the project aint built yet. First do a mvn clean package then try redeploying again.

Java has a feature called "checked exceptions". That means that there are certain kinds of exceptions, namely those that subclass Exception but not RuntimeException, such that if a method may throw them, it must list them in its throws declaration, say: void readData() throws IOException. IOException is one of those.

Thus, when you are calling a method that lists IOException in its throws declaration, you must either list it in your own throws declaration or catch it.

The rationale for the presence of checked exceptions is that for some kinds of exceptions, you must not ignore the fact that they may happen, because their happening is quite a regular situation, not a program error. So, the compiler helps you not to forget about the possibility of such an exception being raised and requires you to handle it in some way.

However, not all checked exception classes in Java standard library fit under this rationale, but that's a totally different topic.

This is how you do CURL with sessions

//initial request with login data

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/login.php');
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/32.0.1700.107 Chrome/32.0.1700.107 Safari/537.36');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "username=XXXXX&password=XXXXX");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie-name');  //could be empty, but cause problems on some hosts
curl_setopt($ch, CURLOPT_COOKIEFILE, '/var/www/ip4.x/file/tmp');  //could be empty, but cause problems on some hosts
$answer = curl_exec($ch);
if (curl_error($ch)) {
    echo curl_error($ch);
}

//another request preserving the session

curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/profile');
curl_setopt($ch, CURLOPT_POST, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, "");
$answer = curl_exec($ch);
if (curl_error($ch)) {
    echo curl_error($ch);
}

I've seen this on ImpressPages

In php 5, you can also hint the type of the passed variable:

function sendemail(array $id, $userid){
  //function body
}

See type hinting.

In Oracle, you can simply subtract two dates and get the difference in days. Also note that unlike SQL Server or MySQL, in Oracle you cannot perform a select statement without a from clause. One way around this is to use the builtin dummy table, dual:

SELECT TO_DATE('2000-01-02', 'YYYY-MM-DD') -  
       TO_DATE('2000-01-01', 'YYYY-MM-DD') AS DateDiff
FROM   dual

You can use CSS under legend.green-color a:hover to do it.

legend.green-color a:hover {
    color:green;
    text-decoration:none;
}

i didn't put my environment variables in the right format as was in the dotenv module documentation e.g. i was doing export TWILIO_CALLER_ID="+wwehehe" and so the dotenv module wasn't parsing my file correctly. When i noticed that i removed the export keyword from the declarations and everything worked fine.

Since i stumbled on the post via google:

Try using npm ci it will be much than an npm install.

From the manual:

In short, the main differences between using npm install and npm ci are:

• The project must have an existing package-lock.json or npm-shrinkwrap.json.
• If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock.
• npm ci can only install entire projects at a time: individual dependencies cannot be added with this command.
• If a node_modules is already present, it will be automatically removed before npm ci begins its install.
• It will never write to package.json or any of the package-locks: installs are essentially frozen.

ko.cleanNode($("#modalPartialView")[0]);
ko.applyBindings(vm, $("#modalPartialView")[0]);

works for me, but as others note, the cleanNode is internal ko function, so there is probably a better way.

Looks like you are using python 2.x. Python 2.x defaults to ascii and it doesn’t know about Unicode. Hence the exception.

Just paste the below line after shebang, it will work

# -*- coding: utf-8 -*-

My friend that's very simple, here an example:

<dependency>
    <groupId>xalan</groupId>
    <artifactId>xalan</artifactId>
    <version>2.7.2</version>
    <scope>${my-scope}</scope>
    <exclusions>
        <exclusion>
        <groupId>xml-apis</groupId>
        <artifactId>xml-apis</artifactId>
    </exclusion>
</dependency>

And if you want to check in the terminal(windows console for this example) that your maven tree has no problems:

mvn dependency:tree -Dverbose | grep --color=always '(.* conflict\|^' | less -r

When download mysql zip version, if run mysqld directly, you'll get this error: 2016-02-18T07:23:48.318481Z 0 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist 2016-02-18T07:23:48.319482Z 0 [ERROR] Aborting

You have to run below command first: mysqld --initialize

Make sure your data folder is empty before this command.

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

Subversion does not yet have a first-class rename operations.

There's a 6-year-old bug on the problem: http://subversion.tigris.org/issues/show_bug.cgi?id=898

It's being considered for 1.6, now that merge tracking (a higher priority) has been added (in 1.5).

You have to redirect output from second java executable to some file. Then, use SendSignal to send "-3" to your second process.

There's a plugin for jQuery called 'rich array' discussed in Rich Array jQuery plugin .

As mentioned earlier, the __del__ functionality is somewhat unreliable. In cases where it might seem useful, consider using the __enter__ and __exit__ methods instead. This will give a behaviour similar to the with open() as f: pass syntax used for accessing files. __enter__ is automatically called when entering the scope of with, while __exit__ is automatically called when exiting it. See this question for more details.

In my copy, Shift + Tab does this, as long as I have a code selection, and am in a code window.

• packed means it will use the smallest possible space for struct Ball - i.e. it will cram fields together without padding
• aligned means each struct Ball will begin on a 4 byte boundary - i.e. for any struct Ball, its address can be divided by 4

These are GCC extensions, not part of any C standard.

Use a JSON library to parse the string and retrieve the value.

The following very basic example uses the built-in JSON parser from Android.

String jsonString = "{ \"name\" : \"John\", \"age\" : \"20\", \"address\" : \"some address\" }";
JSONObject jsonObject = new JSONObject(jsonString);
int age = jsonObject.getInt("age");

More advanced JSON libraries, such as jackson, google-gson, json-io or genson, allow you to convert JSON objects to Java objects directly.

function removeElements(){
  $('#models').html('');
}

The answers provided above are absolutely correct and worth to read but I just wanted to give a straight forward answer to the question.

The question asked is just a type conversion question and here its conversion from int data type to float data type and for that you can do it by the function :

float()

And for more details you can visit this page.

This is not my prefered way to do this, cause of massive CPU consumption.

If that is actually your working code, then just keep it like that. Checking a boolean once a second causes NO measurable CPU load. None whatsoever.

The real problem is that the thread that checks the value may not see a change that has happened for an arbitrarily long time due to caching. To ensure that the value is always synchronized between threads, you need to put the volatile keyword in the variable definition, i.e.

private volatile boolean value;

Note that putting the access in a synchronized block, such as when using the notification-based solution described in other answers, will have the same effect.

I use this:

interface IObjectKeys {
  [key: string]: string | number;
}

interface IDevice extends IObjectKeys {
  id: number;
  room_id: number;
  name: string;
  type: string;
  description: string;
}

If you use the optional property in your object:

interface IDevice extends IObjectKeys {
  id: number;
  room_id?: number;
  name?: string;
  type?: string;
  description?: string;
}

... you should add 'undefined' value into the IObjectKeys interface:

interface IObjectKeys {
  [key: string]: string | number | undefined;
}

Creating a virtual environment for Jupyter Notebooks

A minimal Python install is

sudo apt install python3.7 python3.7-venv python3.7-minimal python3.7-distutils python3.7-dev python3.7-gdbm python3-gdbm-dbg python3-pip

Then you can create and use the environment

/usr/bin/python3.7 -m venv test
cd test
source test/bin/activate
pip install jupyter matplotlib seaborn numpy pandas scipy
# install other packages you need with pip/apt
jupyter notebook
deactivate

You can make a kernel for Jupyter with

ipython3 kernel install --user --name=test

you can find all version install code here by changing the version of laravel doc

composer create-project --prefer-dist laravel/laravel yourProjectName "5.1.*"

above code for creating laravel 5.1 version project. see more in laravel doc. happy coding!!

If you are using text-overflow:ellipsis, the browser will show the contents whatever possible within that container. But if you want to specifiy the number of letters before the dots or strip some contents and add dots, you can use the below function.

function add3Dots(string, limit)
{
  var dots = "...";
  if(string.length > limit)
  {
    // you can also use substr instead of substring
    string = string.substring(0,limit) + dots;
  }
 
    return string;
}

call like

add3Dots("Hello World",9);

outputs

Hello Wor...

See it in action here

function add3Dots(string, limit)
{
  var dots = "...";
  if(string.length > limit)
  {
    // you can also use substr instead of substring
    string = string.substring(0,limit) + dots;
  }

    return string;
}



console.log(add3Dots("Hello, how are you doing today?", 10));

$('.IsBestAnswer').removeClass('IsBestAnswer').addClass('bestanswer');

Your code has two problems:

1. The selector .IsBestAnswe does not match what you thought
2. It's addClass(), not addclass().

Also, I'm not sure whether you want to replace the class or add it. The above will replace, but remove the .removeClass('IsBestAnswer') part to add only:

$('.IsBestAnswer').addClass('bestanswer');

You should decide whether to use camelCase or all-lowercase in your CSS classes too (e.g. bestAnswer vs. bestanswer).

UIAlertView is deprecated on iOS 8. Therefore, to create an alert on iOS 8 and above, it is recommended to use UIAlertController:

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title" message:@"Alert Message" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *defaultAction = [UIAlertAction actionWithTitle:@"Ok" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

    // Enter code here
}];
[alert addAction:defaultAction];

// Present action where needed
[self presentViewController:alert animated:YES completion:nil];

This is how I have implemented it.

Helper to fetch multiple files from a given revision

When trying to resolve merge conflicts, this helper is very useful:

#!/usr/bin/env python3

import argparse
import os
import subprocess

parser = argparse.ArgumentParser()
parser.add_argument('revision')
parser.add_argument('files', nargs='+')
args = parser.parse_args()
toplevel = subprocess.check_output(['git', 'rev-parse', '--show-toplevel']).rstrip().decode()
for path in args.files:
    file_relative = os.path.relpath(os.path.abspath(path), toplevel)
    base, ext = os.path.splitext(path)
    new_path = base + '.old' + ext
    with open(new_path, 'w') as f:
        subprocess.call(['git', 'show', '{}:./{}'.format(args.revision, path)], stdout=f)

GitHub upstream.

Usage:

git-show-save other-branch file1.c path/to/file2.cpp

Outcome: the following contain the alternate versions of the files:

file1.old.c
path/to/file2.old.cpp

This way, you keep the file extension so your editor won't complain, and can easily find the old file just next to the newer one.

Request class doesn't offer a method that would return exactly what you need. But you can easily get it by concatenating results of 2 other methods:

echo (Request::getPathInfo() . (Request::getQueryString() ? ('?' . Request::getQueryString()) : '');

There are two options:

First

You can also use like is()

$('#dropDownId').is(':disabled');

Second

Using == true by checking if the attributes value is disabled. attr()

$('#dropDownId').attr('disabled');

whatever you feel fits better , you can use :)

Cheers!

All the modern browsers provides you storage apis. You can use them (localStorage or sessionStorage) to save your data.

All you have to do is after receiving the response store it to browser storage. Then next time you find the same call, search if the response is saved already. If yes, return the response from there; if not make a fresh call.

Smartjax plugin also does similar things; but as your requirement is just saving the call response, you can write your code inside your jQuery ajax success function to save the response. And before making call just check if the response is already saved.

lastrow = Sheet1.Range("A#").End(xlDown).Row

This is more easy to determine the row count.
Make sure you declare the right variable when it comes to larger rows.
By the way the '#' sign must be a number where you want to start the row count.

I create a file dif.go that contains your code:

package dif

import (
    "time"
)

var StartTime = time.Now()

Outside the folder I create my main.go, it is ok!

package main

import (
    dif "./dif"
    "fmt"
)

func main() {
    fmt.Println(dif.StartTime)
}

Outputs:

2016-01-27 21:56:47.729019925 +0800 CST

Files directory structure:

folder
  main.go
  dif
    dif.go

It works!

Here's an example of how you could implement a list view:

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //We have our list view
    final ListView dynamic = findViewById(R.id.dynamic);

    //Create an array of elements
    final ArrayList<String> classes = new ArrayList<>();
    classes.add("Data Structures");
    classes.add("Assembly Language");
    classes.add("Calculus 3");
    classes.add("Switching Systems");
    classes.add("Analysis Tools");

    //Create adapter for ArrayList
    final ArrayAdapter<String> adapter = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1, classes);

    //Insert Adapter into List
    dynamic.setAdapter(adapter);

    //set click functionality for each list item
    dynamic.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Log.i("User clicked ", classes.get(position));
        }
    });



}

To answer the question asked, here is the most accurate SQL to accomplish the job, you can combine it with PL/SQL loop to actually run kill statements:

select ses.USERNAME,
    substr(MACHINE,1,10) as MACHINE, 
    substr(module,1,25) as module,
    status, 
    'alter system kill session '''||SID||','||ses.SERIAL#||''';' as kill
from v$session ses LEFT OUTER JOIN v$process p ON (ses.paddr=p.addr)
where schemaname <> 'SYS'
    and not exists
    (select 1 
        from DBA_ROLE_PRIVS 
        where GRANTED_ROLE='DBA' 
            and schemaname=grantee)
    and machine!='yourlocalhostname' 
order by LAST_CALL_ET desc;

We can solve this issue so easily.

1. Open a command prompt, and do cd <platform-tools directory>
2. Run command adb kill-server
3. Open Windows Task manager and check whether adb is still running. If it is, just kill adb.exe
4. Run command adb start-server in the command prompt

Don't use array_values on your $row

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
   {
       array_push($res_arr_values, $row);
   }

Also, the preferred way to add a value to an array is writing $array[] = $value;, not using array_push

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
   {
       $res_arr_values[] = $row;
   }

And a further optimization is not to call mysql_fetch_array($result, MYSQL_ASSOC) but to use mysql_fetch_assoc($result) directly.

$res_arr_values = array();
while ($row = mysql_fetch_assoc($result))
   {
       $res_arr_values[] = $row;
   }

In case you came here looking for the issue with ".smproj" file, it is because you are missing SQL Server Analysis Services(SSAS). To over come this, install SQL Server Data Tools(SSDT) in your system, restart your Visual Studio and it will work.

Thanks.

You have two basic options provided by java.util.Collections:

• <T extends Comparable<? super T>> void sort(List<T> list)
  • Use this if T implements Comparable and you're fine with that natural ordering
• <T> void sort(List<T> list, Comparator<? super T> c)
  • Use this if you want to provide your own Comparator.

Depending on what the Collection is, you can also look at SortedSet or SortedMap.

You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.

The ISO-8601 format for a DATETIME when using only the date is: YYYYMMDD (no dashes or antyhing!)

For a DATETIME with the time portion, it's YYYY-MM-DDTHH:MM:SS (with dashes, and a T in the middle to separate date and time portions).

If you want to convert a string to a DATE for SQL Server 2008 or newer, you can use YYYY-MM-DD (with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.

So in your case, you should try:

declare @a datetime
declare @b datetime 

set @a = '2012-04-06T12:23:45'   -- 6th of April, 2012
set @b = '2012-08-06T21:10:12'   -- 6th of August, 2012

exec LogProcedure 'AccountLog', N'test', @a, @b

Furthermore - your stored proc has problem, since you're concatenating together datetime and string into a string, but you're not converting the datetime to string first, and also, you're forgetting the close quotes in your statement after both dates.

So change this line here to this:

IF @DateFirst <> '' and @DateLast <> ''
   SET @FinalSQL  = @FinalSQL + '  OR CONVERT(Date, DateLog) >= ''' + 
                    CONVERT(VARCHAR(50), @DateFirst, 126) +   -- convert @DateFirst to string for concatenation!
                    ''' AND CONVERT(Date, DateLog) <=''' +  -- you need closing quotes after @DateFirst!
                    CONVERT(VARCHAR(50), @DateLast, 126) + ''''      -- convert @DateLast to string and also: closing tags after that missing!

With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.

For ejected create-react-app projects

I just solved my case adding the following lines to my webpack.config.js:

  presets: [
    [
      require.resolve('babel-preset-react-app/dependencies'),
      { helpers: true },
    ],
    /* INSERT START */
    require.resolve('@babel/preset-env'),
    require.resolve('@babel/preset-react'),
      {
      'plugins': ['@babel/plugin-proposal-class-properties']
    } 
    /* INSERTED END */
  ],

Add this line to dependencies in build.gradle:

dependencies {
compile 'com.android.support:appcompat-v7:18.0.+'
}

If you have all the features of type object then the first answer written above works well https://stackoverflow.com/a/31939145/5840973.

But, Suppose when we have mixed type columns. Then we can fetch the list of features names of type object type programmatically and then Label Encode them.

#Fetch features of type Object
objFeatures = dataframe.select_dtypes(include="object").columns

#Iterate a loop for features of type object
from sklearn import preprocessing
le = preprocessing.LabelEncoder()

for feat in objFeatures:
    dataframe[feat] = le.fit_transform(dataframe[feat].astype(str))
 

dataframe.info()

You can create a 'comment' table, with an id as primary key, then you add a text field to capture the text inserted by the user and you need another field to link the comment table to the article table (foreign key). Plus you need a field to store the user that has entered a comment, this field can be the user's email. Then you capture via GET or POST the user's email and comment and you insert everything in the DB:

"INSERT INTO comment (comment, email, approved) VALUES ('$comment', '$email', '$approved')"

This is a first hint. Of course adding a comment feature it takes a little bit. Then you should think about a form to let the admin to approve the comments and how to publish the comments in the end of articles.

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

I've used this simple code in my codebase:

static public string ToReadableByteArray(byte[] bytes)
{
    return string.Join(", ", bytes);
}

To use:

Console.WriteLine(ToReadableByteArray(bytes));

From the top menu "Build" -> "Rebuild Solution", the .exe file was somehow deleted or corrupted, the "Rebuild Solution will create a new one!

In your code you don't get the HttpResponse, so you won't see what the server side sends you back.

you need to get the Response similar to the way you get (make) the Request. So

public static bool SendAnSMSMessage(string message)
{
  var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
  httpWebRequest.ContentType = "text/json";
  httpWebRequest.Method = "POST";

  using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
  {
    string json = "{ \"method\": \"send\", " +
                      "  \"params\": [ " +
                      "             \"IPutAGuidHere\", " +
                      "             \"[email protected]\", " +
                      "             \"MyTenDigitNumberWasHere\", " +
                      "             \"" + message + "\" " +
                      "             ] " +
                      "}";

    streamWriter.Write(json);
  }
  var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
  using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
  {
    var responseText = streamReader.ReadToEnd();
    //Now you have your response.
    //or false depending on information in the response
    return true;        
  }
}

I also notice in the pennysms documentation that they expect a content type of "text/json" and not "application/json". That may not make a difference, but it's worth trying in case it doesn't work.

It's just common stuff for making cin input work faster.

For a quick explanation: the first line turns off buffer synchronization between the cin stream and C-style stdio tools (like scanf or gets) — so cin works faster, but you can't use it simultaneously with stdio tools.

The second line unties cin from cout — by default the cout buffer flushes each time when you read something from cin. And that may be slow when you repeatedly read something small then write something small many times. So the line turns off this synchronization (by literally tying cin to null instead of cout).

The following command helped me (executing on bash before running mvn)

export MAVEN_OPTS=-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

Here's an approach that relies purely on java configuration:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

@Configuration
public class MvcConfig extends WebMvcConfigurationSupport{

    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping handlerMapping = super.requestMappingHandlerMapping();
        handlerMapping.setUseSuffixPatternMatch(false);
        handlerMapping.setUseTrailingSlashMatch(false);
        return handlerMapping;
    }
}

My case is different, I had to kill running Nginx to restart it.

Instead of

sudo systemctl restart nginx

I had to use:

sudo pkill -f nginx & wait $!
sudo systemctl start nginx

If you instead have a jQuery object you want to render instead of the existing content: Then just reset the content and append the new.

var itemtoReplaceContentOf = $('#regTitle');
itemtoReplaceContentOf.html('');
newcontent.appendTo(itemtoReplaceContentOf);

Or:

$('#regTitle').empty().append(newcontent);

The answer is only valid if you have not changed the "Sketchbook Location" field in Preferences. So, first, you need to open the Arduino IDE and go to the menu

"File -> Preferences"

In the dialog, look at the field "Sketchbook Location" and open the corresponding folder. The "libraries" folder in inside.

Here is your answer which is way to solve.You do not want to use jquery when you restricted the user input in textbox control.

<input type="text" id="my_txtbox" readonly />  <!--HTML5-->

<input type="text" id="my_txtbox" readonly="true"/>

>>> s = '23.45678'
>>> int(float(s))
23
>>> int(round(float(s)))
23
>>> s = '23.54678'
>>> int(float(s))
23
>>> int(round(float(s)))
24

You don't specify if you want rounding or not...

Use match to return your desired vector, then cbind it to your matrix

cbind(t, z[, "symbol"][match(rownames(t), rownames(z))])

PS. Be warned that t is base R function that is used to transpose matrices. By creating a variable called t, it can lead to confusion in your downstream code.

if you can't or don't want to set the autoincrement property of the id, you can set value for the id for each row, like this:

INSERT INTO role (id, name, created)
SELECT 
      (select max(id) from role) + ROW_NUMBER() OVER (ORDER BY name)
    , name
    , created
FROM (
    VALUES 
      ('Content Coordinator', GETDATE())
    , ('Content Viewer', GETDATE())
) AS x(name, created)

text() and node() are node tests, in XPath terminology (compare).

Node tests operate on a set (on an axis, to be exact) of nodes and return the ones that are of a certain type. When no axis is mentioned, the child axis is assumed by default.

There are all kinds of node tests:

• node() matches any node (the least specific node test of them all)
• text() matches text nodes only
• comment() matches comment nodes
• * matches any element node
• foo matches any element node named "foo"
• processing-instruction() matches PI nodes (they look like <?name value?>).
• Side note: The * also matches attribute nodes, but only along the attribute axis. @* is a shorthand for attribute::*. Attributes are not part of the child axis, that's why a normal * does not select them.

This XML document:

<produce>
    <item>apple</item>
    <item>banana</item>
    <item>pepper</item>
</produce>

represents the following DOM (simplified):

root node
   element node (name="produce")
      text node (value="\n    ")
      element node (name="item")
         text node (value="apple")
      text node (value="\n    ")
      element node (name="item")
         text node (value="banana")
      text node (value="\n    ")
      element node (name="item")
         text node (value="pepper")
      text node (value="\n")

So with XPath:

• / selects the root node
• /produce selects a child element of the root node if it has the name "produce" (This is called the document element; it represents the document itself. Document element and root node are often confused, but they are not the same thing.)
• /produce/node() selects any type of child node beneath /produce/ (i.e. all 7 children)
• /produce/text() selects the 4 (!) whitespace-only text nodes
• /produce/item[1] selects the first child element named "item"
• /produce/item[1]/text() selects all child text nodes (there's only one - "apple" - in this case)

And so on.

So, your questions

• "Select the text of all items under produce" /produce/item/text() (3 nodes selected)
• "Select all the manager nodes in all departments" //department/manager (1 node selected)

Notes

• The default axis in XPath is the child axis. You can change the axis by prefixing a different axis name. For example: //item/ancestor::produce
• Element nodes have text values. When you evaluate an element node, its textual contents will be returned. In case of this example, /produce/item[1]/text() and string(/produce/item[1]) will be the same.
• Also see this answer where I outline the individual parts of an XPath expression graphically.

I use .forEach to iterate over , and push result to results array then use it, with this solution I will not loop over array twice

There are several places colon is used in Java code:

1) Jump-out label (Tutorial):

label: for (int i = 0; i < x; i++) {
    for (int j = 0; j < i; j++) {
        if (something(i, j)) break label; // jumps out of the i loop
    }
} 
// i.e. jumps to here

2) Ternary condition (Tutorial):

int a = (b < 4)? 7: 8; // if b < 4, set a to 7, else set a to 8

3) For-each loop (Tutorial):

String[] ss = {"hi", "there"}
for (String s: ss) {
    print(s); // output "hi" , and "there" on the next iteration
}

4) Assertion (Guide):

int a = factorial(b);
assert a >= 0: "factorial may not be less than 0"; // throws an AssertionError with the message if the condition evaluates to false

5) Case in switch statement (Tutorial):

switch (type) {
    case WHITESPACE:
    case RETURN:
        break;
    case NUMBER:
        print("got number: " + value);
        break;
    default:
        print("syntax error");
}

6) Method references (Tutorial)

class Person {
   public static int compareByAge(Person a, Person b) {
       return a.birthday.compareTo(b.birthday);
   }}
}

Arrays.sort(persons, Person::compareByAge);

<div id="container">
  <table width="100%" height="100%">
    <tr>
      <td align="center" valign="middle">

Generate a protected application for Mac or Windows from your Excel spreadsheet using OfficeProtect with either AppProtect or QuickLicense/AddLicense. There is a demonstation video called "Protect Excel Spreedsheet" at www.excelsoftware.com/videos.

I expanded on @BenMcCormicks a bit. His worked for regular strings but not if I had escaped characters or wildcards. Here's what I did

str = "[curl] 6: blah blah 234433 blah blah";
mapObj = {'\\[curl] *': '', '\\d: *': ''};


function replaceAll (str, mapObj) {

    var arr = Object.keys(mapObj),
        re;

    $.each(arr, function (key, value) {
        re = new RegExp(value, "g");
        str = str.replace(re, function (matched) {
            return mapObj[value];
        });
    });

    return str;

}
replaceAll(str, mapObj)

returns "blah blah 234433 blah blah"

This way it will match the key in the mapObj and not the matched word'

As it may happens that the default branch of your submodules are not master (which happens a lot in my case), this is how I automate the full Git submodules upgrades:

git submodule init
git submodule update
git submodule foreach 'git fetch origin; git checkout $(git rev-parse --abbrev-ref HEAD); git reset --hard origin/$(git rev-parse --abbrev-ref HEAD); git submodule update --recursive; git clean -dfx'

Follow the steps below:

1- git stash
2- git add .
3- git commit -m "your commit message"

• Make sure the file exists: use os.listdir() to see the list of files in the current working directory
• Make sure you're in the directory you think you're in with os.getcwd() (if you launch your code from an IDE, you may well be in a different directory)
• You can then either:
  • Call os.chdir(dir), dir being the folder where the file is located, then open the file with just its name like you were doing.
  • Specify an absolute path to the file in your open call.
• Remember to use a raw string if your path uses backslashes, like so: dir = r'C:\Python32'
  • If you don't use raw-string, you have to escape every backslash: 'C:\\User\\Bob\\...'
  • Forward-slashes also work on Windows 'C:/Python32' and do not need to be escaped.

Let me clarify how Python finds files:

• An absolute path is a path that starts with your computer's root directory, for example 'C:\Python\scripts..' if you're on Windows.
• A relative path is a path that does not start with your computer's root directory, and is instead relative to something called the working directory. You can view Python's current working directory by calling os.getcwd().

If you try to do open('sortedLists.yaml'), Python will see that you are passing it a relative path, so it will search for the file inside the current working directory. Calling os.chdir will change the current working directory.

Example: Let's say file.txt is found in C:\Folder.

To open it, you can do:

os.chdir(r'C:\Folder')
open('file.txt') #relative path, looks inside the current working directory

or

open(r'C:\Folder\file.txt') #full path

Visibility is an animatable property according to the spec, but transitions on visibility do not work gradually, as one might expect. Instead transitions on visibility delay hiding an element. On the other hand making an element visible works immediately. This is as it is defined by the spec (in the case of the default timing function) and as it is implemented in the browsers.

This also is a useful behavior, since in fact one can imagine various visual effects to hide an element. Fading out an element is just one kind of visual effect that is specified using opacity. Other visual effects might move away the element using e.g. the transform property, also see http://taccgl.org/blog/css-transition-visibility.html

It is often useful to combine the opacity transition with a visibility transition! Although opacity appears to do the right thing, fully transparent elements (with opacity:0) still receive mouse events. So e.g. links on an element that was faded out with an opacity transition alone, still respond to clicks (although not visible) and links behind the faded element do not work (although being visible through the faded element). See http://taccgl.org/blog/css-transition-opacity-for-fade-effects.html.

This strange behavior can be avoided by just using both transitions, the transition on visibility and the transition on opacity. Thereby the visibility property is used to disable mouse events for the element while opacity is used for the visual effect. However care must be taken not to hide the element while the visual effect is playing, which would otherwise not be visible. Here the special semantics of the visibility transition becomes handy. When hiding an element the element stays visible while playing the visual effect and is hidden afterwards. On the other hand when revealing an element, the visibility transition makes the element visible immediately, i.e. before playing the visual effect.

If you are trying to get the id, then please update your code like

  html += '<option id = "' + n.id + "' value="' + i + '">' + n.names + '</option>';

To retrieve id,

$('option:selected').attr("id")

To retrieve Value

$('option:selected').val()

in Javascript

var e = document.getElementById("jobSel");
var job = e.options[e.selectedIndex].value;

select * from shirts where find_in_set('1',colors) <> 0

Works for me

On MacOSX, by combining the answers from Calaf and Ollie Ford, the following worked for me.

On the command line (be sure adb is in your path, mine was at ~/Library/Android/sdk/platform-tools/adb) and with your android device plugged in and in USB debugging mode, run:

 adb backup -f backup com.mypackage.myapp

Your android device will ask you for permission to backup your data. Select "BACKUP MY DATA"

Wait a few moments.

The file backup will appear in the directory where you ran adb.

Now run:

dd if=backup bs=1 skip=24 | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" > backup.tar

Now you'll you have a backup.tar file you can untar like this:

 tar xvf backup.tar

And see all the files stored by your application.

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

If you need to use foreach (for some reason) and don't want to use bult-in functions, here is a code snippet:

int minint = array[0];
int maxint = array[0];
foreach (int value in array) {
  if (value < minint) minint = value;
  if (value > maxint) maxint = value;
}

Follow these steps:

• Select the Start button, then type cmd.
• Right-click the Command Prompt option, then choose Run as administrator.
• Type net use, then press Enter.
• Look for any drives listed that may be questionable. In many cases where this problem occurs, the drive may not be assigned a letter. You’ll want to remove that drive.
• From the Command Prompt, type net use /delete \\servername\foldername where the servername\foldername is the drive that you wish to delete.

It's a new paradigm called "Unobtrusive JavaScript". The current "web standard" says to separate functionality and presentation.

It's not really a "bad practice", it's just that most new standards want you to use event listeners instead of in-lining JavaScript.

Also, this may just be a personal thing, but I think it's much easier to read when you use event listeners, especially if you have more than 1 JavaScript statement you want to run.

For me only this one worked

git checkout -p filename

I know this post is very old. I was actually looking for a solution to this myself. Some of the solutions posted work but they're pretty long so I decided to write my own version.

Directory.GetParent("./../..")

Basically what it does is:

1. . = will leave you in the same directory you are currently in.
2. / = in this context, the directory seperator.
3. .. = will move you one directory back (2x).
4. GetParent() = get the parent folder of ./../..

Combining all this together will leave you with: C:\Users\Oushima\Desktop\Homework\OoP\Assignment 1\part 1, (\part 1 being my project folder).

This is what worked for me. It's very similar to .Parent.Parent but shorter. I hope this will help someone else out.

If you want it to 100% return a string datatype then you can put .FullName behind it. Oh, and, don't forget the using System.IO; C# reference.

I've been using Typescript in my current angular project for about a year and a half and while there are a few issues with definitions every now and then the DefinitelyTyped project does an amazing job at keeping up with the latest versions of most popular libraries.

Having said that there is a definite learning curve when transitioning from vanilla JavaScript to TS and you should take into account the ability of you and your team to make that transition. Also if you are going to be using angular 1.x most of the examples you will find online will require you to translate them from JS to TS and overall there are not a lot of resources on using TS and angular 1.x together right now.

If you plan on using angular 2 there are a lot of examples using TS and I think the team will continue to provide most of the documentation in TS, but you certainly don't have to use TS to use angular 2.

ES6 does have some nice features and I personally plan on getting more familiar with it but I would not consider it a production-ready language at this point. Mainly due to a lack of support by current browsers. Of course, you can write your code in ES6 and use a transpiler to get it to ES5, which seems to be the popular thing to do right now.

Overall I think the answer would come down to what you and your team are comfortable learning. I personally think both TS and ES6 will have good support and long futures, I prefer TS though because you tend to get language features quicker and right now the tooling support (in my opinion) is a little better.

@Jay Mooney: A generic Dictionary class in .NET is actually a hash table, just with fixed types.

The code you've shown shouldn't convince anyone to use Hashtable instead of Dictionary, since both code pieces can be used for both types.

For hashtable:

foreach(object key in h.keys)
{
     string keyAsString = key.ToString(); // btw, this is unnecessary
     string valAsString = h[key].ToString();

     System.Diagnostics.Debug.WriteLine(keyAsString + " " + valAsString);
}

For dictionary:

foreach(string key in d.keys)
{
     string valAsString = d[key].ToString();

     System.Diagnostics.Debug.WriteLine(key + " " + valAsString);
}

And just the same for the other one with KeyValuePair, just use the non-generic version for Hashtable, and the generic version for Dictionary.

So it's just as easy both ways, but Hashtable uses Object for both key and value, which means you will box all value types, and you don't have type safety, and Dictionary uses generic types and is thus better.

Even though this is an old question, I 've stumbled upon this issue multiple times and until now never figured out how to fix it. The update maven indices is a term coined by IntelliJ, and if it still doesn't work after you've compiled the first project, chances are that you are using 2 different maven installations.

Press CTRL+Shift+A to open up the Actions menu. Type Maven and go to Maven Settings. Check the Home Directory to use the same maven as you use via the command line

find . -name \*.cc -print0 -or -name \*.h -print0 | xargs -0 grep "hello".

Check the manual pages for find and xargs for details.

An alternative General Plan, which I'm only adding as an independent Answer because the blasted "comment on an answer" won't take newlines without posting the entire edit, even though it isn't finished yet.

UPDATE table A
JOIN table B ON {join fields}
JOIN table C ON {join fields}
JOIN {as many tables as you need}
SET A.column = {expression}

Example:

UPDATE person P
JOIN address A ON P.home_address_id = A.id
JOIN city C ON A.city_id = C.id
SET P.home_zip = C.zipcode;

Be careful of difference between 'c' and "c"

'c' is a char suitable for formatting with %c

"c" is a char* pointing to a memory block with a length of 2 (with the null terminator).

I needed my ASP.NET drop down list to take up all available space, and this is all I put in the CSS and it is working in Firefox and IE11:

If you have a list and you want to know where within the list an element exists that matches a given criteria, you can use the FindIndex instance method. Such as

int index = list.FindIndex(f => f.Bar == 17);

Where f => f.Bar == 17 is a predicate with the matching criteria.

In your case you might write

int index = pricePublicList.FindIndex(item => item.Size == 200);
if (index >= 0) 
{
    // element exists, do what you need

there's also an interesting tool called CUFON. There's a demonstration of how to use it in this blog It's really simple and interesting. Also, it doesn't allow people to ctrl+c/ctrl+v the generated content.

You have to add the FormHttpMessageConverter to your applicationContext.xml to be able to post multipart files.

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter" />
            <bean class="org.springframework.http.converter.FormHttpMessageConverter" />
        </list>
    </property>
</bean>

See http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/http/converter/FormHttpMessageConverter.html for examples.

My take on Christians solution.

git archive --prefix=deploy/  master | tar -x -C $TMPDIR | rsync $TMPDIR/deploy/ --copy-links -av [email protected]:/home/user/my_app && rm -rf $TMPDIR/deploy

• Archives the master branch into tar
• Extracts tar archive into deploy dir in system temp folder.
• rsync changes into server
• delete deploy dir from temp folder.

You can also do this without using groupby or loc. By simply including the condition in code. Let the name of dataframe be df. Then you can try :

df[df['a']==1]['b'].sum()

or you can also try :

sum(df[df['a']==1]['b'])

Another way could be to use the numpy library of python :

import numpy as np
print(np.where(df['a']==1, df['b'],0).sum())

Create a table with a normal numeric auto_increment ID, but either define it with ZEROFILL, or use LPAD to add zeroes when selecting. Then CONCAT the values to get your intended behavior. Example #1:

create table so (
 id int(3) unsigned zerofill not null auto_increment primary key,
 name varchar(30) not null
);

insert into so set name = 'John';
insert into so set name = 'Mark';

select concat('LHPL', id) as id, name from so;
+---------+------+
| id      | name |
+---------+------+
| LHPL001 | John |
| LHPL002 | Mark |
+---------+------+

Example #2:

create table so (
 id int unsigned not null auto_increment primary key,
 name varchar(30) not null
);

insert into so set name = 'John';
insert into so set name = 'Mark';

select concat('LHPL', LPAD(id, 3, 0)) as id, name from so;
+---------+------+
| id      | name |
+---------+------+
| LHPL001 | John |
| LHPL002 | Mark |
+---------+------+

First I executed:

sudo chown -R $(whoami):admin /usr/local

Then:

cd $(brew --prefix) && git fetch origin && git reset --hard origin/master

I tried this code, it may work for you also:

            DateFormat dateFormat2 = new SimpleDateFormat("dd"); 
            Date date2 = new Date();

            String today = dateFormat2.format(date2); 

            //find the calendar
            WebElement dateWidget = driver.findElement(By.id("dp-calendar"));  
            List<WebElement> columns=dateWidget.findElements(By.tagName("td"));  

            //comparing the text of cell with today's date and clicking it.
            for (WebElement cell : columns)
            {
               if (cell.getText().equals(today))
               {
                  cell.click();
                  break;
               }
            }

If you are importing file1.py from file2.py and used this:

if __name__ == '__main__':
    # etc

Variables below that in file1.py cannot be imported to file2.py because __name__ does not equal __main__!

If you want to import something from file1.py to file2.py, you need to use this in file1.py:

if __name__ == 'file1':
    # etc

In case of doubt, make an assert statement to determine if __name__=='__main__'

How about calling the .NET Framework methods?

You can do ANYTHING with them... :

[System.IO.File]::Copy($src, $dest, $true);

The $true argument makes it overwrite.

With Bootstrap 4, just use this CSS:

.carousel .carousel-item {
    transition-duration: 3s;
}

Change 3s to the duration of your choice.

Like what Volker mentioned, nested structs is the way to go. But if you really do not want nested structs, you can override the UnmarshalJSON func.

https://play.golang.org/p/dqn5UdqFfJt

type A struct {
    FooBar string // takes foo.bar
    FooBaz string // takes foo.baz
    More   string 
}

func (a *A) UnmarshalJSON(b []byte) error {

    var f interface{}
    json.Unmarshal(b, &f)

    m := f.(map[string]interface{})

    foomap := m["foo"]
    v := foomap.(map[string]interface{})

    a.FooBar = v["bar"].(string)
    a.FooBaz = v["baz"].(string)
    a.More = m["more"].(string)

    return nil
}

Please ignore the fact that I'm not returning a proper error. I left that out for simplicity.

UPDATE: Correctly retrieving "more" value.

You could use CSS for this and create classes for the elements. So you'd have something like this

p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }

Then your HTML would read:

<p class="detail">My Name is: <span class="name">Tintinecute</span> </p>

It's a lot neater then inline stylesheets, is easier to maintain and provides greater reuse.

Here's the complete HTML to demonstrate what I mean:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <style type="text/css">
    p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
    span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }
    </style>
</head>
<body>
    <p class="detail">My Name is: <span class="name">Tintinecute</span> </p>
</body>
</html>     

You'll see that I have the stylesheet classes in a style tag in the header, and then I only apply those classes in the code such as <p class="detail"> ... </p>. Go through the w3schools tutorial, it will only take a couple of hours and will really turn you around when it comes to styling your HTML elements. If you cut and paste that into an HTML document you can edit the styles and see what effect they have when you open the file in a browser. Experimenting like this is a great way to learn.

Generate keys

I am using /etc/mysql for cert storage because /etc/apparmor.d/usr.sbin.mysqld contains /etc/mysql/*.pem r.

sudo su -
cd /etc/mysql
openssl genrsa -out ca-key.pem 2048;
openssl req -new -x509 -nodes -days 1000 -key ca-key.pem -out ca-cert.pem;
openssl req -newkey rsa:2048 -days 1000 -nodes -keyout server-key.pem -out server-req.pem;
openssl x509 -req -in server-req.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 -out server-cert.pem;
openssl req -newkey rsa:2048 -days 1000 -nodes -keyout client-key.pem -out client-req.pem;
openssl x509 -req -in client-req.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 -out client-cert.pem;

Add configuration

/etc/mysql/my.cnf

[client]
ssl-ca=/etc/mysql/ca-cert.pem
ssl-cert=/etc/mysql/client-cert.pem
ssl-key=/etc/mysql/client-key.pem

[mysqld]
ssl-ca=/etc/mysql/ca-cert.pem
ssl-cert=/etc/mysql/server-cert.pem
ssl-key=/etc/mysql/server-key.pem

On my setup, Ubuntu server logged to: /var/log/mysql/error.log

Follow up notes:

• SSL error: Unable to get certificate from '...'

  MySQL might be denied read access to your certificate file if it is not in apparmors configuration. As mentioned in the previous steps^, save all our certificates as .pem files in the /etc/mysql/ directory which is approved by default by apparmor (or modify your apparmor/SELinux to allow access to wherever you stored them.)

• SSL error: Unable to get private key

  Your MySQL server version may not support the default rsa:2048 format

  Convert generated rsa:2048 to plain rsa with:

  openssl rsa -in server-key.pem -out server-key.pem
  openssl rsa -in client-key.pem -out client-key.pem
  

• Check if local server supports SSL:

  mysql -u root -p
  mysql> show variables like "%ssl%";
  +---------------+----------------------------+
  | Variable_name | Value                      |
  +---------------+----------------------------+
  | have_openssl  | YES                        |
  | have_ssl      | YES                        |
  | ssl_ca        | /etc/mysql/ca-cert.pem     |
  | ssl_capath    |                            |
  | ssl_cert      | /etc/mysql/server-cert.pem |
  | ssl_cipher    |                            |
  | ssl_key       | /etc/mysql/server-key.pem  |
  +---------------+----------------------------+
  

• Verifying a connection to the database is SSL encrypted:

  Verifying connection

  When logged in to the MySQL instance, you can issue the query:

  show status like 'Ssl_cipher';
  

  If your connection is not encrypted, the result will be blank:

  mysql> show status like 'Ssl_cipher';
  +---------------+-------+
  | Variable_name | Value |
  +---------------+-------+
  | Ssl_cipher    |       |
  +---------------+-------+
  1 row in set (0.00 sec)
  

  Otherwise, it would show a non-zero length string for the cypher in use:

  mysql> show status like 'Ssl_cipher';
  +---------------+--------------------+
  | Variable_name | Value              |
  +---------------+--------------------+
  | Ssl_cipher    | DHE-RSA-AES256-SHA |
  +---------------+--------------------+
  1 row in set (0.00 sec)
  

• Require ssl for specific user's connection ('require ssl'):

  • SSL

  Tells the server to permit only SSL-encrypted connections for the account.

  GRANT ALL PRIVILEGES ON test.* TO 'root'@'localhost'
    REQUIRE SSL;
  

  To connect, the client must specify the --ssl-ca option to authenticate the server certificate, and may additionally specify the --ssl-key and --ssl-cert options. If neither --ssl-ca option nor --ssl-capath option is specified, the client does not authenticate the server certificate.

Alternate link: Lengthy tutorial in Secure PHP Connections to MySQL with SSL.

I will put a small comparison table here (just to have it somewhere):

Servlet is mapped as /test%3F/* and the application is deployed under /app.

getParameterNames()     yes     [p 2, p 1]
getParameter("p 1")     yes     c d

In the example above the server is running on the localhost:8480 and the name 30thh.loc was put into OS hosts file.

Comments

• "+" is handled as space only in the query string

• Anchor "#a" is not transferred to the server. Only the browser can work with it.

• If the url-pattern in the servlet mapping does not end with * (for example /test or *.jsp), getPathInfo() returns null.

If Spring MVC is used

• Method getPathInfo() returns null.

• Method getServletPath() returns the part between the context path and the session ID. In the example above the value would be /test?/a?+b

• Be careful with URL encoded parts of @RequestMapping and @RequestParam in Spring. It is buggy (current version 3.2.4) and is usually not working as expected.

Why don't you take a look to this answer

Including javascript files inside javascript files

In short you can load the script file with AJAX or put a script tag on the HTML to include it( before the script that uses the functions of the other script). The link I posted is a great answer and has multiple examples and explanations of both methods.

Try this:

git clone --recurse-submodules

It automatically pulls in the submodule data assuming you have already added the submodules to the parent project.

For Windows or Linux users, a possible solution is described on GitHub Docs, which I report below for your convenience.

You can run ssh-agent automatically when you open bash or Git shell. Copy the following lines and paste them into your ~/.profile or ~/.bashrc file:

env=~/.ssh/agent.env

agent_load_env () { test -f "$env" && . "$env" >| /dev/null ; }

agent_start () {
    (umask 077; ssh-agent >| "$env")
    . "$env" >| /dev/null ; }

agent_load_env

# agent_run_state: 0=agent running w/ key; 1=agent w/o key; 2= agent not running
agent_run_state=$(ssh-add -l >| /dev/null 2>&1; echo $?)

if [ ! "$SSH_AUTH_SOCK" ] || [ $agent_run_state = 2 ]; then
    agent_start
    ssh-add
elif [ "$SSH_AUTH_SOCK" ] && [ $agent_run_state = 1 ]; then
    ssh-add
fi

unset env

If your private key is not stored in one of the default locations (like ~/.ssh/id_rsa), you'll need to tell your SSH authentication agent where to find it. To add your key to ssh-agent, type ssh-add ~/path/to/my_key.

Now, when you first run Git Bash, you are prompted for your passphrase. The ssh-agent process will continue to run until you log out, shut down your computer, or kill the process.

Simple use of _.each

_.each(['Hello', 'World!'], function(word){_x000D_
    console.log(word);_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

Here's simple example that could use _.each:

function basket() {_x000D_
    this.items = [];_x000D_
    this.addItem = function(item) {_x000D_
        this.items.push(item);_x000D_
    };_x000D_
    this.show = function() {_x000D_
        console.log('items: ', this.items);_x000D_
    }_x000D_
}_x000D_
_x000D_
var x = new basket();_x000D_
x.addItem('banana');_x000D_
x.addItem('apple');_x000D_
x.addItem('kiwi');_x000D_
x.show();

Output:

items:  [ 'banana', 'apple', 'kiwi' ]

Instead of calling addItem multiple times you could use underscore this way:

_.each(['banana', 'apple', 'kiwi'], function(item) { x.addItem(item); });

which is identical to calling addItem three times sequentially with these items. Basically it iterates your array and for each item calls your anonymous callback function that calls x.addItem(item). The anonymous callback function is similar to addItem member function (e.g. it takes an item) and is kind of pointless. So, instead of going through anonymous function it's better that _.each avoids this indirection and calls addItem directly:

_.each(['banana', 'apple', 'kiwi'], x.addItem);

but this won't work, as inside basket's addItem member function this won't refer to your x basket that you created. That's why you have an option to pass your basket x to be used as [context]:

_.each(['banana', 'apple', 'kiwi'], x.addItem, x);

Full example that uses _.each and context:

function basket() {_x000D_
    this.items = [];_x000D_
    this.addItem = function(item) {_x000D_
        this.items.push(item);_x000D_
    };_x000D_
    this.show = function() {_x000D_
        console.log('items: ', this.items);_x000D_
    }_x000D_
}_x000D_
var x = new basket();_x000D_
_.each(['banana', 'apple', 'kiwi'], x.addItem, x);_x000D_
x.show();

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

In short, if callback function that you pass to _.each in any way uses this then you need to specify what this should be referring to inside your callback function. It may seem like x is redundant in my example, but x.addItem is just a function and could be totally unrelated to x or basket or any other object, for example:

function basket() {_x000D_
    this.items = [];_x000D_
    this.show = function() {_x000D_
        console.log('items: ', this.items);_x000D_
    }_x000D_
}_x000D_
function addItem(item) {_x000D_
    this.items.push(item);_x000D_
};_x000D_
_x000D_
var x = new basket();_x000D_
_.each(['banana', 'apple', 'kiwi'], addItem, x);_x000D_
x.show();

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

In other words, you bind some value to this inside your callback, or you may as well use bind directly like this:

_.each(['banana', 'apple', 'kiwi'], addItem.bind(x));

how this feature can be useful with some different underscore methods?

In general, if some underscorejs method takes a callback function and if you want that callback be called on some member function of some object (e.g. a function that uses this) then you may bind that function to some object or pass that object as the [context] parameter and that's the primary intention. And at the top of underscorejs documentation, that's exactly what they state: The iteratee is bound to the context object, if one is passed

Since you return to the client just String and its content type == 'text/plain', there is no any chance for default converters to determine how to convert String response to the FFSampleResponseHttp object.

The simple way to fix it:

• remove expected-response-type from <int-http:outbound-gateway>
• add to the replyChannel1 <json-to-object-transformer>

Otherwise you should write your own HttpMessageConverter to convert the String to the appropriate object.

To make it work with MappingJackson2HttpMessageConverter (one of default converters) and your expected-response-type, you should send your reply with content type = 'application/json'.

If there is a need, just add <header-enricher> after your <service-activator> and before sending a reply to the <int-http:inbound-gateway>.

So, it's up to you which solution to select, but your current state doesn't work, because of inconsistency with default configuration.

UPDATE

OK. Since you changed your server to return FfSampleResponseHttp object as HTTP response, not String, just add contentType = 'application/json' header before sending the response for the HTTP and MappingJackson2HttpMessageConverter will do the stuff for you - your object will be converted to JSON and with correct contentType header.

From client side you should come back to the expected-response-type="com.mycompany.MyChannel.model.FFSampleResponseHttp" and MappingJackson2HttpMessageConverter should do the stuff for you again.

Of course you should remove <json-to-object-transformer> from you message flow after <int-http:outbound-gateway>.

This is an easy one:

textField.setFocus();

If you are using DbContext and EF v6+, alternatively you can use:

this.context.Database.CommandTimeout = 180;

Do it in this format:

classmehodisin.methodname();

For example:

MyClass1.clearscreen();

I hope this helped.` Note:The method must be static.

I had the same problem. I solved it the following way :

1. Go to Settings->Storage->Click the USB icon at top
2. Make sure that MTP is selected

CURLOPT_POSTFIELDS as the name suggests, is for the body (payload) of a POST request. For GET requests, the payload is part of the URL in the form of a query string.

In your case, you need to construct the URL with the arguments you need to send (if any), and remove the other options to cURL.

curl_setopt($ch, CURLOPT_URL, $this->service_url.'user/'.$id_user);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);

//$body = '{}';
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET"); 
//curl_setopt($ch, CURLOPT_POSTFIELDS,$body);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

This works for me:

version: '3.1'
services:
  db:
    image: postgres
  web:
    build: .
    command:
      - /bin/bash
      - -c
      - |
        python manage.py migrate
        python manage.py runserver 0.0.0.0:8000

    volumes:
      - .:/code
    ports:
      - "8000:8000"
    links:
      - db

docker-compose tries to dereference variables before running the command, so if you want bash to handle variables you'll need to escape the dollar-signs by doubling them...

    command:
      - /bin/bash
      - -c
      - |
        var=$$(echo 'foo')
        echo $$var # prints foo

...otherwise you'll get an error:

Invalid interpolation format for "command" option in service "web":

string sentence = "This is a sentence with multiple    spaces";
RegexOptions options = RegexOptions.None;
Regex regex = new Regex("[ ]{2,}", options);     
sentence = regex.Replace(sentence, " ");

Check that the application on the test device and Google Play developer console really match.

I might have a bit of a special case but it might help someone: First, I had uploaded a package to Google Play that I had created with an ant build script. Second, on the test device, I debugged the same application (or so I thought). I got the "Error while retrieving information from server. [RPC:S-7:AEC-0]", and logcat displayed:

Class not found when unmarshalling: com.google.android.finsky.billing.lightpurchase.PurchaseParams, e: java.lang.ClassNotFoundException: com.google.android.finsky.billing.lightpurchase.PurchaseParams

The problem was that in the ant script, I have aapt command for modifying the package name. However, Eclipse does not run that command, so there was a package name mismatch between the applications in Google Play and the test device.

The approach I've found workable is git's submodule system. Using that you can submodule in a given version of the code and upgrading/downgrading is explicit and recorded - never haphazard.

The folder structure I've taken with this is:

+ myproject
++ src
+++ myproject
+++ github.com
++++ submoduled_project of some kind.

   var form = $('#job-request-form')[0];
        var formData = new FormData(form);
        event.preventDefault();
        $.ajax({
            url: "/send_resume/", // the endpoint
            type: "POST", // http method
            processData: false,
            contentType: false,
            data: formData,

It worked for me! just set processData and contentType False.

Very late to the thread, but a technique I've used, pre-Angular, is to take advantage of JSON and the flexibility of JS to dynamically reference collection keys, and use inalienable facts of the environment (host server name, current browser language, etc.) as inputs to selectively discriminate/prefer suffixed key names within a JSON data structure.

This provides not merely deploy-environment context (per OP) but any arbitrary context (such as language) to provide i18n or any other variance required simultaneously, and (ideally) within a single configuration manifest, without duplication, and readably obvious.

IN ABOUT 10 LINES VANILLA JS

Overly-simplified but classic example: An API endpoint base URL in a JSON-formatted properties file that varies per environment where (natch) the host server will also vary:

    ...
    'svcs': {
        'VER': '2.3',
        'API@localhost': 'http://localhost:9090/',
        '[email protected]': 'https://www.uat.productionwebsite.com:9090/res/',
        '[email protected]': 'https://www.productionwebsite.com:9090/api/res/'
    },
    ...

A key to the discrimination function is simply the server hostname in the request.

This, naturally, can be combined with an additional key based on the user's language settings:

    ...
    'app': {
        'NAME': 'Ferry Reservations',
        'NAME@fr': 'Réservations de ferry',
        'NAME@de': 'Fähren Reservierungen'
    },
    ...

The scope of the discrimination/preference can be confined to individual keys (as above) where the "base" key is only overwritten if there's a matching key+suffix for the inputs to the function -- or an entire structure, and that structure itself recursively parsed for matching discrimination/preference suffixes:

    'help': {
        'BLURB': 'This pre-production environment is not supported. Contact Development Team with questions.',
        'PHONE': '808-867-5309',
        'EMAIL': '[email protected]'
    },
    '[email protected]': {
        'BLURB': 'Please contact Customer Service Center',
        'BLURB@fr': 'S\'il vous plaît communiquer avec notre Centre de service à la clientèle',
        'BLURB@de': 'Bitte kontaktieren Sie unseren Kundendienst!!1!',
        'PHONE': '1-800-CUS-TOMR',
        'EMAIL': '[email protected]'
    },

SO, if a visiting user to the production website has German (de) language preference setting, the above configuration would collapse to:

    'help': {
        'BLURB': 'Bitte kontaktieren Sie unseren Kundendienst!!1!',
        'PHONE': '1-800-CUS-TOMR',
        'EMAIL': '[email protected]'
    },

What does such a magical preference/discrimination JSON-rewriting function look like? Not much:

// prefer(object,suffix|[suffixes]) by/par/durch storsoc
// prefer({ a: 'apple', a@env: 'banana', b: 'carrot' },'env') -> { a: 'banana', b: 'carrot' }
function prefer(o,sufs) {
    for (var key in o) {
        if (!o.hasOwnProperty(key)) continue; // skip non-instance props
        if(key.split('@')[1]) { // suffixed!
            // replace root prop with the suffixed prop if among prefs
            if(o[key] && sufs.indexOf(key.split('@')[1]) > -1) o[key.split('@')[0]] = JSON.parse(JSON.stringify(o[key]));

            // and nuke the suffixed prop to tidy up
            delete o[key];

            // continue with root key ...
            key = key.split('@')[0];
        }

        // ... in case it's a collection itself, recurse it!
        if(o[key] && typeof o[key] === 'object') prefer(o[key],sufs);

    };
};

In our implementations, which include Angular and pre-Angular websites, we simply bootstrap the configuration well ahead of other resource calls by placing the JSON within a self-executing JS closure, including the prefer() function, and fed basic properties of hostname and language-code (and accepts any additional arbitrary suffixes you might need):

(function(prefs){ var props = {
    'svcs': {
        'VER': '2.3',
        'API@localhost': 'http://localhost:9090/',
        '[email protected]': 'https://www.uat.productionwebsite.com:9090/res/',
        '[email protected]': 'https://www.productionwebsite.com:9090/api/res/'
    },
    ...
    /* yadda yadda moar JSON und bisque */

    function prefer(o,sufs) {
        // body of prefer function, broken for e.g.
    };

    // convert string and comma-separated-string to array .. and process it
    prefs = [].concat( ( prefs.split ? prefs.split(',') : prefs ) || []);
    prefer(props,prefs);
    window.app_props = JSON.parse(JSON.stringify(props));
})([location.hostname, ((window.navigator.userLanguage || window.navigator.language).split('-')[0])  ] );

A pre-Angular site would now have a collapsed (no @ suffixed keys) window.app_props to refer to.

An Angular site, as a bootstrap/init step, simply copies the dead-dropped props object into $rootScope, and (optionally) destroys it from global/window scope

app.constant('props',angular.copy(window.app_props || {})).run( function ($rootScope,props) { $rootScope.props = props; delete window.app_props;} );

to be subsequently injected into controllers:

app.controller('CtrlApp',function($log,props){ ... } );

or referred to from bindings in views:

<span>{{ props.help.blurb }} {{ props.help.email }}</span>

Caveats? The @ character is not valid JS/JSON variable/key naming, but so far accepted. If that's a deal-breaker, substitute for any convention you like, such as "__" (double underscore) as long as you stick to it.

The technique could be applied server-side, ported to Java or C# but your efficiency/compactness may vary.

Alternately, the function/convention could be part of your front-end compile script, so that the full gory all-environment/all-language JSON is never transmitted over the wire.

UPDATE

We've evolved usage of this technique to allow multiple suffixes to a key, to avoid being forced to use collections (you still can, as deeply as you want), and as well to honor the order of the preferred suffixes.

Example (also see working jsFiddle):

var o = { 'a':'apple', 'a@dev':'apple-dev', 'a@fr':'pomme',
          'b':'banana', 'b@fr':'banane', 'b@dev&fr':'banane-dev',
          'c':{ 'o':'c-dot-oh', 'o@fr':'c-point-oh' }, 'c@dev': { 'o':'c-dot-oh-dev', 'o@fr':'c-point-oh-dev' } };

/*1*/ prefer(o,'dev');        // { a:'apple-dev', b:'banana',     c:{o:'c-dot-oh-dev'}   }
/*2*/ prefer(o,'fr');         // { a:'pomme',     b:'banane',     c:{o:'c-point-oh'}     }
/*3*/ prefer(o,'dev,fr');     // { a:'apple-dev', b:'banane-dev', c:{o:'c-point-oh-dev'} }
/*4*/ prefer(o,['fr','dev']); // { a:'pomme',     b:'banane-dev', c:{o:'c-point-oh-dev'} }
/*5*/ prefer(o);              // { a:'apple',     b:'banana',     c:{o:'c-dot-oh'}       }

1/2 (basic usage) prefers '@dev' keys, discards all other suffixed keys

3 prefers '@dev' over '@fr', prefers '@dev&fr' over all others

4 (same as 3 but prefers '@fr' over '@dev')

5 no preferred suffixes, drops ALL suffixed properties

It accomplishes this by scoring each suffixed property and promoting the value of a suffixed property to the non-suffixed property when iterating over the properties and finding a higher-scored suffix.

Some efficiencies in this version, including removing dependence on JSON to deep-copy, and only recursing into objects that survive the scoring round at their depth:

function prefer(obj,suf) {
    function pr(o,s) {
        for (var p in o) {
            if (!o.hasOwnProperty(p) || !p.split('@')[1] || p.split('@@')[1] ) continue; // ignore: proto-prop OR not-suffixed OR temp prop score
            var b = p.split('@')[0]; // base prop name
            if(!!!o['@@'+b]) o['@@'+b] = 0; // +score placeholder
            var ps = p.split('@')[1].split('&'); // array of property suffixes
            var sc = 0; var v = 0; // reset (running)score and value
            while(ps.length) {
                // suffix value: index(of found suffix in prefs)^10
                v = Math.floor(Math.pow(10,s.indexOf(ps.pop())));
                if(!v) { sc = 0; break; } // found suf NOT in prefs, zero score (delete later)
                sc += v;
            }
            if(sc > o['@@'+b]) { o['@@'+b] = sc; o[b] = o[p]; } // hi-score! promote to base prop
            delete o[p];
        }
        for (var p in o) if(p.split('@@')[1]) delete o[p]; // remove scores
        for (var p in o) if(typeof o[p] === 'object') pr(o[p],s); // recurse surviving objs
    }
    if( typeof obj !== 'object' ) return; // validate
    suf = ( (suf || suf === 0 ) && ( suf.length || suf === parseFloat(suf) ) ? suf.toString().split(',') : []); // array|string|number|comma-separated-string -> array-of-strings
    pr(obj,suf.reverse());
}

If you're in Rails, .blank? should be the method you are looking for:

a = nil
b = []
c = ""

a.blank? #=> true
b.blank? #=> true
c.blank? #=> true

d = "1"
e = ["1"]

d.blank? #=> false
e.blank? #=> false

So the answer would be:

variable = id if variable.blank?

colo schema_name works fine if you are facing problems with colorscheme.

You've declared the class Thing as a non-static inner class. That means it must be associated with an instance of the Hello class.

In your code, you're trying to create an instance of Thing from a static context. That is what the compiler is complaining about.

There are a few possible solutions. Which solution to use depends on what you want to achieve.

• Move Thing out of the Hello class.

• Change Thing to be a static nested class.

  static class Thing
  

• Create an instance of Hello before creating an instance of Thing.

  public static void main(String[] args)
  {
      Hello h = new Hello();
      Thing thing1 = h.new Thing(); // hope this syntax is right, typing on the fly :P
  }
  

The last solution (a non-static nested class) would be mandatory if any instance of Thing depended on an instance of Hello to be meaningful. For example, if we had:

public class Hello {
    public int enormous;

    public Hello(int n) {
        enormous = n;
    }

    public class Thing {
        public int size;

        public Thing(int m) {
            if (m > enormous)
                size = enormous;
            else
                size = m;
        }
    }
    ...
}

any raw attempt to create an object of class Thing, as in:

Thing t = new Thing(31);

would be problematic, since there wouldn't be an obvious enormous value to test 31 against it. An instance h of the Hello outer class is necessary to provide this h.enormous value:

...
Hello h = new Hello(30);
...
Thing t = h.new Thing(31);
...

Because it doesn't mean a Thing if it doesn't have a Hello.

Maybe another question is, "what are you going to do with those indices once you get them?" If you are going to use them to create another list, then in Python, they are an unnecessary middle step. If you want all the values that match a given condition, just use the builtin filter:

matchingVals = filter(lambda x : x>2, a)

Or write your own list comprhension:

matchingVals = [x for x in a if x > 2]

If you want to remove them from the list, then the Pythonic way is not to necessarily remove from the list, but write a list comprehension as if you were creating a new list, and assigning back in-place using the listvar[:] on the left-hand-side:

a[:] = [x for x in a if x <= 2]

Matlab supplies find because its array-centric model works by selecting items using their array indices. You can do this in Python, certainly, but the more Pythonic way is using iterators and generators, as already mentioned by @EliBendersky.

Then use + to combine strings:

console.log("story " + name + " story");

Have a look at ImmutableMap JavaDoc: doc

There is information about that there:

Unlike Collections.unmodifiableMap(java.util.Map), which is a view of a separate map which can still change, an instance of ImmutableMap contains its own data and will never change. ImmutableMap is convenient for public static final maps ("constant maps") and also lets you easily make a "defensive copy" of a map provided to your class by a caller.

1) "container" is a class and not an ID 2) .container - set z-index and display: none in your CSS and not inline unless there is a really good reason to do so. Demo@fiddle

$("#button").click(function() {
    $(".container").css("opacity", 0.2);
   $("#loading-img").css({"display": "block"});
});

CSS:

#loading-img {
    background: url(http://web.bogdanteodoru.com/wp-content/uploads/2012/01/bouncy-css3-loading-animation.jpg) center center no-repeat;  /* different for testing purposes */
    display: none;
    height: 100px; /* for testing purposes */
    z-index: 12;
}

In JavaScript you can encode single quotes as "\x27" and double quotes as "\x22". Therefore, with this method you can, once you're inside the (double or single) quotes of a JavaScript string literal, use the \x27 \x22 with impunity without fear of any embedded quotes "breaking out" of your string.

\xXX is for chars < 127, and \uXXXX for Unicode, so armed with this knowledge you can create a robust JSEncode function for all characters that are out of the usual whitelist.

For example,

<a href="#" onclick="SelectSurveyItem('<% JSEncode(itemid) %>', '<% JSEncode(itemname) %>'); return false;">Select</a>

I believe you're looking for...

import config.logging_settings  # @UnusedImport

Note the double space before the comment to avoid hitting other formatting warnings.

Also, depending on your IDE (if you're using one), there's probably an option to add the correct ignore rule (e.g., in Eclipse, pressing Ctrl + 1, while the cursor is over the warning, will auto-suggest @UnusedImport).

My working solution is:

cd /opt/genymobile/genymotion/tools
./adb shell

You have to use its own adb tool.

Use this. It will work. I have used bootstrap 3.3.5 and jquery 1.11.3

If you're still getting this error message while using the WCF Test Client, it's because the client has a separate MaxBufferSize setting.

To correct the issue:

1. Right-Click on the Config File node at the bottom of the tree
2. Select Edit with SvcConfigEditor

A list of editable settings will appear, including MaxBufferSize.

Note: Auto-generated proxy clients also set MaxBufferSize to 65536 by default.

I ran into a new one for this: SQL 2012 hosted on Server 2012. Was tasked to create a cluster for SQL AlwaysOn.
Cluster was created everyone got the SSPI message.

To fix the problems ran following command:

setspn -D MSSQLSvc/SERVER_FQNName:1433 DomainNamerunningSQLService

DomainNamerunningSQLService == the domain account I set for SQL I needed a Domain Administrator to run the command. Only one server in the cluster had issues.

Then restarted SQL. To my surprise I was able to connect.

private IEnumerable<TextBox> GetTextBoxes(Control control)
{
    if (control is TextBox textBox)
    {
        yield return textBox;
    }

    if (control.HasChildren)
    {
        foreach (Control ctr in control.Controls)
        {
            foreach (var textbox in GetTextBoxes(ctr))
            {
                yield return textbox;
            }
        }
    }
}

I'd recommend that you take a look at jQuery.

jQuery way:

$("html").addClass("myClass");

The smallest change to fix this would be to change

onClick="document.getElementById("datepicker").click()">

to

onClick="$('#datepicker').click()">

click() is a jQuery method. Also, you had a collision between the double-quotes used for the HTML element attribute and those use for the JavaScript function argument.

Use theme():

d <- data.frame(x=gl(10, 1, 10, labels=paste("long text label ", letters[1:10])), y=rnorm(10))
ggplot(d, aes(x=x, y=y)) + geom_point() +
    theme(text = element_text(size=20),
        axis.text.x = element_text(angle=90, hjust=1)) 
#vjust adjust the vertical justification of the labels, which is often useful

There's lots of good information about how to format your ggplots here. You can see a full list of parameters you can modify (basically, all of them) using ?theme.

Yes for some reason WebView.reload() causes a crash if it failed to load before (something to do with the way it handles history). This is the code I use to refresh my webview. I store the current url in self.url

# 1: Pause timeout and page loading

self.timeout.pause()
sleep(1)

# 2: Check for internet connection (Really lazy way)

while self.page().networkAccessManager().networkAccessible() == QNetworkAccessManager.NotAccessible: sleep(2)

# 3:Try again

if self.url == self.page().mainFrame().url():
    self.page().action(QWebPage.Reload)
    self.timeout.resume(60)

else:
    self.page().action(QWebPage.Stop)
    self.page().mainFrame().load(self.url)
    self.timeout.resume(30)

return False

A pure javascript solution (without jQuery):

const SEARCH_DELAY = 100; // in ms

// it may run indefinitely. TODO: make it cancellable, using Promise's `reject`
function waitForElementToBeAdded(cssSelector) {
  return new Promise((resolve) => {
    const interval = setInterval(() => {
      if (element = document.querySelector(cssSelector)) {
        clearInterval(interval);
        resolve(element);
      }
    }, SEARCH_DELAY);
  });
}

console.log(await waitForElementToBeAdded('#main'));

You can use the CSS3 Linear Gradient property along with your background-image like this:

#landing-wrapper {
    display:table;
    width:100%;
    background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
    background-position:center top;
    height:350px;
}

Here's a demo:

#landing-wrapper {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
  background-position: center top;_x000D_
  height: 350px;_x000D_
  color: white;_x000D_
}

<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>

just FYI in GoDaddy it's this:

AddHandler x-httpd-php5-3 .php

In case you are trying to build a jar with kotlin you need to create a src/main/java folder and use this folder as a location for the META-INF folder.

I tried and found out that if you add a class called btn you can get that hand or cursor icon if you hover over the mouse to that element. Try and see.

Example:

<span class="btn">Hovering over must have mouse cursor set to hand or pointer!</span>

Cheers!

None of the answers here worked for me. What I had to do is:

1. Re-run the installer.
2. Select the quick action 're-configure' next to product 'MySQL Server'
3. Go through the options till you reach Authentication Method and select 'Use Legacy Authentication Method'

After that it works fine.

Use Pypdf or its successor PyPDF2:

A Pure-Python library built as a PDF toolkit. It is capable of:
* splitting documents page by page,
* merging documents page by page,

(and much more)

Here's a sample program that works with both versions.

#!/usr/bin/env python
import sys
try:
    from PyPDF2 import PdfFileReader, PdfFileWriter
except ImportError:
    from pyPdf import PdfFileReader, PdfFileWriter

def pdf_cat(input_files, output_stream):
    input_streams = []
    try:
        # First open all the files, then produce the output file, and
        # finally close the input files. This is necessary because
        # the data isn't read from the input files until the write
        # operation. Thanks to
        # https://stackoverflow.com/questions/6773631/problem-with-closing-python-pypdf-writing-getting-a-valueerror-i-o-operation/6773733#6773733
        for input_file in input_files:
            input_streams.append(open(input_file, 'rb'))
        writer = PdfFileWriter()
        for reader in map(PdfFileReader, input_streams):
            for n in range(reader.getNumPages()):
                writer.addPage(reader.getPage(n))
        writer.write(output_stream)
    finally:
        for f in input_streams:
            f.close()

if __name__ == '__main__':
    if sys.platform == "win32":
        import os, msvcrt
        msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY)
    pdf_cat(sys.argv[1:], sys.stdout)

To get rid of the if/else awkwardness you could use a using block:

@{
    var count = 0;
    foreach (var item in Model)
    {
        using(Html.TableRow(new { @class = (count++ % 2 == 0) ? "alt-row" : "" }))
        {
            <td>
                @Html.DisplayFor(modelItem => item.Title)
            </td>
            <td>
                @Html.Truncate(item.Details, 75)
            </td>
            <td>
                <img src="@Url.Content("~/Content/Images/Projects/")@item.Images.Where(i => i.IsMain == true).Select(i => i.Name).Single()" 
                    alt="@item.Images.Where(i => i.IsMain == true).Select(i => i.AltText).Single()" class="thumb" />
            </td>
            <td>
                @Html.ActionLink("Edit", "Edit", new { id=item.ProjectId }) |
                @Html.ActionLink("Details", "Details", new { id = item.ProjectId }) |
                @Html.ActionLink("Delete", "Delete", new { id=item.ProjectId })
            </td>
        }
    }
}

Reusable element that make it easier to add attributes:

//Block is take from http://www.codeducky.org/razor-trick-using-block/
public class TableRow : Block
{
    private object _htmlAttributes;
    private TagBuilder _tr;

    public TableRow(HtmlHelper htmlHelper, object htmlAttributes) : base(htmlHelper)
    {
        _htmlAttributes = htmlAttributes;
    }

    public override void BeginBlock()
    {
        _tr = new TagBuilder("tr");
        _tr.MergeAttributes(HtmlHelper.AnonymousObjectToHtmlAttributes(_htmlAttributes));
        this.HtmlHelper.ViewContext.Writer.Write(_tr.ToString(TagRenderMode.StartTag));
    }

    protected override void EndBlock()
    {
        this.HtmlHelper.ViewContext.Writer.Write(_tr.ToString(TagRenderMode.EndTag));
    }
}

Helper method to make razor syntax clearer:

public static TableRow TableRow(this HtmlHelper self, object htmlAttributes)
{
    var tableRow = new TableRow(self, htmlAttributes);
    tableRow.BeginBlock();
    return tableRow;
}

With Rails 4 it's easy:

 Foo.includes(:bar).where.not(bars: {id: nil})

Kind of, use the XmlAttribute instead of XmlElement, but it won't look like what you want. It will look like the following:

<SomeModel SomeStringElementName="testData"> 
</SomeModel> 

The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.

// TODO: make the class generic so that an int or string can be used.
[Serializable]  
public class SerializationClass
{
    public SerializationClass(string value)
    {
        this.Value = value;
    }

    [XmlAttribute("value")]
    public string Value { get; }
}


[Serializable]                     
public class SomeModel                     
{                     
    [XmlIgnore]                     
    public string SomeString { get; set; }                     

    [XmlIgnore]                      
    public int SomeInfo { get; set; }  

    [XmlElement]
    public SerializationClass SomeStringElementName
    {
        get { return new SerializationClass(this.SomeString); }
    }               
}

I'm not sure if this is a good solution but it removed the error. I commented out the line:

from numpy._distributor_init import NUMPY_MKL 

and it worked. Not sure if this will cause other features to break though

This is thrown when

... the peer was not able to identify itself (for example; no certificate, the particular cipher suite being used does not support authentication, or no peer authentication was established during SSL handshaking) this exception is thrown.

Probably the cause of this exception (where is the stacktrace) will show you why this exception is thrown. Most likely the default keystore shipped with Java does not contain (and trust) the root certificate of the TTP that is being used.

The answer is to retrieve the root certificate (e.g. from your browsers SSL connection), import it into the cacerts file and trust it using keytool which is shipped by the Java JDK. Otherwise you will have to assign another trust store programmatically.

Or if you need to match only the beginning of words:

WHERE interests LIKE 'sports%' OR interests LIKE 'pub%'

you can use the regexp caret matches:

WHERE interests REGEXP '^sports|^pub'

Set the define character to something other than &

SET DEFINE ~
create table blah (x varchar(20));
insert into blah (x) values ('blah&amp');
select * from blah;

X                    
-------------------- 
blah&amp 

Another alternative is;

sudo iptables -A INPUT -p tcp --dport 8000 -s ! 1.2.3.4 -j DROP

I had similar issue that 3 bridged virtualmachine just need access eachother with different combination, so I have tested this command and it works well.

Edit**

According to Fernando comment and this link exclamation mark (!) will be placed before than -s parameter:

sudo iptables -A INPUT -p tcp --dport 8000 ! -s 1.2.3.4 -j DROP

1. Open MySQL Workbench (6.3 CE)
2. In "Navigator" select "Management"
3. Then select "Data Export" (Here select the table whose create script you wish to export)
4. In Drop down select "Dump Structure and Data"
5. Select checkbox "Include Create Schema"
6. Click the button "Start Export" Once export is complete it will display the location in which exported file is dumped in your system. Go to the location and open the exported file to find table creation script.

Or Check https://dev.mysql.com/doc/workbench/en/wb-admin-export-import-management.html

I wanted a solution for Gnu sort on Windows, but none of the above solutions worked for me on the command line.

Using Lloyd's clue, the following batch file (.bat) worked for me.

Type the tab character within the double quotes.

C:\>cat foo.bat

sort -k3 -t"    " tabfile.txt

Instead of using a dot, like: 1.2, try to input like this: 1,2.

If you are trying to do that in a Portable Class Library PCL (like me), then here is how you can do it :)

public class Foo
{
   public string A {get;set;}

   [Special]
   public string B {get;set;}   
}

var type = typeof(Foo);

var specialProperties = type.GetRuntimeProperties()
     .Where(pi => pi.PropertyType == typeof (string) 
      && pi.GetCustomAttributes<Special>(true).Any());

You can then check on the number of properties that have this special property if you need to.

Yes that's possible you have to define your own style for radio buttons, at res/values/styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CustomTheme" parent="android:Theme">
   <item name="android:radioButtonStyle">@style/RadioButton</item>
</style>
<style name="RadioButton" parent="@android:style/Widget.CompoundButton.RadioButton">
   <item name="android:button">@drawable/radio</item>
</style>
</resources>

'radio' here should be a stateful drawable, radio.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:state_window_focused="false"
        android:drawable="@drawable/radio_hover" />
    <item android:state_checked="false" android:state_window_focused="false"
        android:drawable="@drawable/radio_normal" />
    <item android:state_checked="true" android:state_pressed="true"
        android:drawable="@drawable/radio_active" />
    <item android:state_checked="false" android:state_pressed="true"
        android:drawable="@drawable/radio_active" />
    <item android:state_checked="true" android:state_focused="true"
        android:drawable="@drawable/radio_hover" />
    <item android:state_checked="false" android:state_focused="true"
        android:drawable="@drawable/radio_normal_off" />
    <item android:state_checked="false" android:drawable="@drawable/radio_normal" />
    <item android:state_checked="true" android:drawable="@drawable/radio_hover" />
    </selector>

Then just apply the Custom theme either to whole app or to activities of your choice.

For more info about themes and styles look at http://brainflush.wordpress.com/2009/03/15/understanding-android-themes-and-styles/ that is good guide.

To answer the question more generally, the answer is:

select: function( event , ui ) {
    alert( "You selected: " + ui.item.label );
}

Complete example :

$('#test').each(function(i, el) {_x000D_
    var that = $(el);_x000D_
    that.autocomplete({_x000D_
        source: ['apple','banana','orange'],_x000D_
        select: function( event , ui ) {_x000D_
            alert( "You selected: " + ui.item.label );_x000D_
        }_x000D_
    });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/themes/smoothness/jquery-ui.css" />_x000D_

Type a fruit here: <input type="text" id="test" />

firstOrCreate() checks for all the arguments to be present before it finds a match. If not all arguments match, then a new instance of the model will be created.

If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value']) with only one item in the array. This will return the first item that matches, or create a new one if not matches are found.

The difference between firstOrCreate() and firstOrNew():

• firstOrCreate() will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.
• firstOrNew() will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save() on the model). Otherwise it will give you the matched item.

Choosing between one or the other depends on what you want to do. If you want to modify the model instance before it is saved for the first time (e.g. setting a name or some mandatory field), you should use firstOrNew(). If you can just use the arguments to immediately create a new model instance in the database without modifying it, you can use firstOrCreate().

Try with opacity

div { transition: all 0.4s ease }_x000D_
.hide { opacity: 0; }

<input onclick="newpost.classList.toggle('hide')" type="button" value="toggle">_x000D_
_x000D_
<div id="newpost">Hello</div>

Try css:

.topcorner{
    position:absolute;
    top:10px;
    right: 10px;
 }

you can play with the top and right properties.

If you want to float the div even when you scroll down, just change position:absolute; to position:fixed;.

Hope it helps.

Use this method:

private static bool ContainsKey(this NameValueCollection collection, string key)
{
    if (collection.Get(key) == null)
    {
        return collection.AllKeys.Contains(key);
    }

    return true;
}

It is the most efficient for NameValueCollection and doesn't depend on does collection contain null values or not.

Ok, first e.preventDefault(); it's not a Jquery element, it's a method of javascript, now what it's true it's if you add this method you avoid the submit the event, now what you could do it's send the form by ajax something like this

$('#subscription_order_form').submit(function(e){
    $.ajax({
     url: $(this).attr('action'),
     data : $(this).serialize(),
     success : function (data){

      }
   });
    e.preventDefault();
});

It's a conceptual problem.

Stringstream is a stream, so its iterators are forward, cannot return. In an output stringstream, you need a flush() to reinitialize it, as in any other output stream.

i had same problem i solved it like that , here are newbies step by step instruction

first create object of child form it top of your form class , then use that object for every operation of child form like showing child form and reading value from it.

example

namespace ParentChild
{
   // Parent Form Class
    public partial class ParentForm : Form
    {
        // Forms Objects
        ChildForm child_obj = new ChildForm();


        // Show Child Forrm
        private void ShowChildForm_Click(object sender, EventArgs e)
        {
            child_obj.ShowDialog();
        }

       // Read Data from Child Form 
        private void ReadChildFormData_Click(object sender, EventArgs e)
        {
            int ChildData = child_obj.child_value;  // it will have 12345
        }

   }  // parent form class end point


   // Child Form Class
    public partial class ChildForm : Form
    {

        public int child_value = 0;   //  variable where we will store value to be read by parent form  

        // save something into child_value  variable and close child form 
        private void SaveData_Click(object sender, EventArgs e)
        {
            child_value = 12345;   // save 12345 value to variable
            this.Close();  // close child form
        }

   }  // child form class end point


}  // name space end point

The easiest way is to use to_datetime:

df['col'] = pd.to_datetime(df['col'])

It also offers a dayfirst argument for European times (but beware this isn't strict).

Here it is in action:

In [11]: pd.to_datetime(pd.Series(['05/23/2005']))
Out[11]:
0   2005-05-23 00:00:00
dtype: datetime64[ns]

You can pass a specific format:

In [12]: pd.to_datetime(pd.Series(['05/23/2005']), format="%m/%d/%Y")
Out[12]:
0   2005-05-23
dtype: datetime64[ns]

If you want to identify slow queries, than the method is to use log_min_duration_statement setting (in postgresql.conf or set per-database with ALTER DATABASE SET).

When you logged the data, you can then use grep or some specialized tools - like pgFouine or my own analyzer - which lacks proper docs, but despite this - runs quite well.

Some modifications were made on posted answer UnderWaterKremlin to make it python3 proof. A surprising result below as answer.

System specs:

• python =3.7.4,
• conda = 4.8.0
• 3.6Ghz, 8 core, 16gb.

import timeit

d = {x: x**2 for x in range(1000)}
#print (d)
print (len(d))
# 1000

print (len(d.keys()))
# 1000

print (timeit.timeit('len({x: x**2 for x in range(1000)})', number=100000))        # 1

print (timeit.timeit('len({x: x**2 for x in range(1000)}.keys())', number=100000)) # 2

Result:

1) = 37.0100378

2) = 37.002148899999995

So it seems that len(d.keys()) is currently faster than just using len().

CSS

li {
   display: inline-block;
}

Works for me also.

PDT eclipse from ZEND has a mac version (PDT all-in-one).

I've been using it for about 3 months and it's pretty solid and has debugging capabilities with xdebug (debug howto) and zend debugger.

Alternatively to a redirect, if it is calling your own code, you could use this:

actionContext.Result = new RedirectToRouteResult(
    new RouteValueDictionary(new { controller = "Home", action = "Error" })
);

actionContext.Result.ExecuteResult(actionContext.Controller.ControllerContext);

It is not a pure redirect but gives a similar result without unnecessary overhead.

If you want to use NASM and Visual Studio's linker (link.exe) with anderstornvig's Hello World example you will have to manually link with the C Runtime Libary that contains the printf() function.

nasm -fwin32 helloworld.asm
link.exe helloworld.obj libcmt.lib

Hope this helps someone.

So, if you are using flask_restful Package for API's returning 201 would becomes like

def bla(*args, **kwargs):
    ...
    return data, 201

where data should be any hashable/ JsonSerialiable value, like dict, string.

On OS X, where date does not support the %N flag, I recommend installing coreutils using Homebrew. This will give you access to a command called gdate that will behave as date does on Linux systems.

brew install coreutils

For a more "native" experience, you can always add this to your .bash_aliases:

alias date='gdate'

Then execute

$ date +%s%N

You have a <script> element that is trying to load some external JavaScript.

The URL you have given it points to a JSON file and not a JavaScript program.

The server is correctly reporting that it is JSON so the browser is aborting with that error message instead of trying to execute the JSON as JavaScript (which would throw an error).

Odds are that the underlying reason for this is that you are trying to make an Ajax request, have hit a cross origin error and have tried to fix it by telling jQuery that you are using JSONP. This only works if the URL provides JSONP (which is a different subset of JavaScript), which this one doesn't.

The same URL with the additional query string parameter callback=the_name_of_your_callback_function does return JavaScript though.

I think this is better, following the good practices of passing parameters to the query:

BookingDates::whereRaw('email = ? or name like ?', [$request->email,"%{$request->name}%"])->get();

You can see it in the documentation, Laravel 5.5.

You can also use the Laravel scout and make it easier with search. Here is the documentation.

You can pass an object as argument to the Thread.Start and use it as a shared data storage between the current thread and the initiating thread.

You can also just directly access (with the appropriate locking of course) your data members, if you started the thread using the instance form of the ThreadStart delegate.

You can't use attributes to create shared data between threads. You can use the attribute instances attached to your class as a data storage, but I fail to see how that is better than using static or instance data members.

cycles, arrays, regexp... for what? It can be much quicker :)

function isVowel(char)
{
    return char === 'a' || char === 'e' || char === 'i' || char === 'o' || char === 'u' || false;
}

Most of the people have given good answers. I would also like to contribute something here. I am providing the answer using lodash library to iterate through all command line arguments we pass while starting the app:

// Lodash library
const _ = require('lodash');

// Function that goes through each CommandLine Arguments and prints it to the console.
const runApp = () => {
    _.map(process.argv, (arg) => {
        console.log(arg);
    });
};

// Calling the function.
runApp();

To run above code just run following commands:

npm install
node index.js xyz abc 123 456

The result will be:

xyz 
abc 
123
456

If error comes for ".settings/language.settings.xml" or any such file you don't need to git.

1. Team -> Commit -> Staged filelist, check if unwanted file exists, -> Right click on each-> remove from index.
2. From UnStaged filelist, check if unwanted file exists, -> Right click on each-> Ignore.

Now if Staged file list empty, and Unstaged file list all files are marked as Ignored. You can pull. Otherwise, follow other answers.

A constructor allows you to initialize an object's properties upon creation of the object.

If you create a __construct() function, PHP will automatically call this function when you create an object from a class.

https://www.w3schools.com/php/php_oop_constructor.asp

import org.apache.commons.lang.math.NumberUtils;

This will handle null

NumberUtils.createLong(String)

This are just php notice messages,it seems php.ini configurations are not according vtiger standards, you can disable this message by setting error reporting to E_ALL & ~E_NOTICE in php.ini For example error_reporting(E_ALL&~E_NOTICE) and then restart apache to reflect changes.

I faced same issue (VS 2015), but my application is running under 32-bit application pool. So even though machine is 64-bit. I installed 32-bit installation and it works.

From React v16.02 you can use a Fragment.

<MyComponent text={<Fragment>This is an <strong>HTML</strong> string.</Fragment>} />

More info: https://reactjs.org/blog/2017/11/28/react-v16.2.0-fragment-support.html

This worked for me (on Windows via CMD):

pip install --proxy proxyserver:port requests

It would be:

config/databases.yml
cache
log
data/sql
lib/filter/base
lib/form/base
lib/model/map
lib/model/om

or possibly even:

config/databases.yml
cache
log
data/sql
lib/*/base
lib/model/map
lib/model/om

in case that filter and form are the only directories in lib that do have a basesubdirectory that needs to be ignored (see it as an example of what you can do with the asterics).

Watch this.

The video says that you need to just add self.view.layoutIfNeeded() like the following:

UIView.animate(withDuration: 1.0, animations: {
       self.centerX.constant -= 75
       self.view.layoutIfNeeded()
}, completion: nil)

1. Where does user.id go after passport.serializeUser has been called?

The user id (you provide as the second argument of the done function) is saved in the session and is later used to retrieve the whole object via the deserializeUser function.

serializeUser determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}

2. We are calling passport.deserializeUser right after it where does it fit in the workflow?

The first argument of deserializeUser corresponds to the key of the user object that was given to the done function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc). In deserializeUser that key is matched with the in memory array / database or any data resource.

The fetched object is attached to the request object as req.user

Visual Flow

passport.serializeUser(function(user, done) {
    done(null, user.id);
});              ¦
                 ¦ 
                 ¦
                 +--------------------? saved to session
                                   ¦    req.session.passport.user = {id: '..'}
                                   ¦
                                   ?           
passport.deserializeUser(function(id, done) {
                   +---------------+
                   ¦
                   ? 
    User.findById(id, function(err, user) {
        done(err, user);
    });            +--------------? user object attaches to the request as req.user   
});

In Magento 2 You have to remove file located in /var/.maintenance.flag - just realized that after some searching, so i shall share.

HTML:
 <div id="container"></div>   
JS:


$('#search').click(function() {
    $.ajax({
        type: 'POST',
        url: 'cityResults.htm',
        data: $('#cityDetails').serialize(),
        dataType:"json", //to parse string into JSON object,
        success: function(data){ 

                var len = data.length;
                var txt = "";
                if(len > 0){
                    for(var i=0;i<len;i++){

                            txt = "<tr><td>"+data[i].city+"</td><td>"+data[i].cStatus+"</td></tr>";
                            $("#container").append(txt);
                    }



        },
        error: function(jqXHR, textStatus, errorThrown){
            alert('error: ' + textStatus + ': ' + errorThrown);
        }
    });
    return false;
});

For Groovy script in the Jenkinsfile using the $BUILD_NUMBER it works.

You can't. I think you have FOUR options here. All four offer a solution but with a slightly different approach...

Option One: use the built-in name() on an enum. This is perfectly fine if you don't need any special naming format.

    String name = Modes.mode1.name(); // Returns the name of this enum constant, exactly as declared in its enum declaration.

Option Two: add overriding properties to your enums if you want more control

public enum Modes {
    mode1 ("Fancy Mode 1"),
    mode2 ("Fancy Mode 2"),
    mode3 ("Fancy Mode 3");

    private final String name;       

    private Modes(String s) {
        name = s;
    }

    public boolean equalsName(String otherName) {
        // (otherName == null) check is not needed because name.equals(null) returns false 
        return name.equals(otherName);
    }

    public String toString() {
       return this.name;
    }
}

Option Three: use static finals instead of enums:

public final class Modes {

    public static final String MODE_1 = "Fancy Mode 1";
    public static final String MODE_2 = "Fancy Mode 2";
    public static final String MODE_3 = "Fancy Mode 3";

    private Modes() { }
}

Option Four: interfaces have every field public, static and final:

public interface Modes {

    String MODE_1 = "Fancy Mode 1";
    String MODE_2 = "Fancy Mode 2";
    String MODE_3 = "Fancy Mode 3";  
}
