Programs & Examples On #Multiple matches

My solution is to use a function to create a table with the date intervals and then join this table to the data I want to group using the date interval in the table. The date interval can then be easily selected when presenting the data.

CREATE FUNCTION [dbo].[fn_MinuteIntervals]
    (
      @startDate SMALLDATETIME ,
      @endDate SMALLDATETIME ,
      @interval INT = 1
    )
RETURNS @returnDates TABLE
    (
      [date] SMALLDATETIME PRIMARY KEY NOT NULL
    )
AS
    BEGIN
        DECLARE @counter SMALLDATETIME
        SET @counter = @startDate
        WHILE @counter <= @endDate
            BEGIN
                INSERT INTO @returnDates VALUES ( @counter )
                SET @counter = DATEADD(n, @interval, @counter)
            END
        RETURN
    END

DateTime doesn't have a default key as an input. The default key should be an input to the Column function. Try this:

import datetime
from sqlalchemy import Column, Integer, DateTime
from sqlalchemy.ext.declarative import declarative_base

Base = declarative_base()

class Test(Base):
    __tablename__ = 'test'

    id = Column(Integer, primary_key=True)
    created_date = Column(DateTime, default=datetime.datetime.utcnow)

You don't specify which shell (there are many), so I am assuming Bourne Shell, that is I think your script starts with:

#!/bin/sh

Please remember to tag future questions with the shell type, as this will help the community answer your question.

You need to define your functions before you call them. Using ():

process_install()
{
    echo "Performing process_install() commands, using arguments [${*}]..."
}

process_exit()
{
    echo "Performing process_exit() commands, using arguments [${*}]..."
}

Then you can call your functions, just as if you were calling any command:

if [ "$choice" = "true" ]
then
    process_install foo bar
elif [ "$choice" = "false" ]
then
    process_exit baz qux

You may also wish to check for invalid choices at this juncture...

else
    echo "Invalid choice [${choice}]..."
fi

See it run with three different values of ${choice}.

Good luck!

I fixed this issue by reinstalling it in Program Files, it originally tried to install it in c:/Users/.../AppData/Android/....

Mine was caused by a user permission issue that running as admin didn't seem to fix (perhaps because they call batch files?).

Fetch does not use cookie by default. To enable cookie, do this:

fetch(url, {
  credentials: "same-origin"
}).then(...).catch(...);

I suggest you to use StringBuilder class for it and than parse it to string if you need.

System.Text.StringBuilder strBuilder = new System.Text.StringBuilder("valta is the best place in the World");
strBuilder[0] = 'M';
string str=strBuilder.ToString();

You can't change string's characters in this way, because in C# string isn't dynamic and is immutable and it's chars are readonly. For make sure in it try to use methods of string, for example, if you do str.ToLower() it makes new string and your previous string doesn't change.

Problem was my package name. It MUST be "com.outbottle" (then config/controllers/model/etc) for it to work. As you can see above, I used Maven (for the first time), Spring, 1.8 JDK and nearly had a stroke debugging this issue. All running on Glassfish (Tomcat is ok too for the above pom config). That said, I'm all happy with myself now and know Maven and Spring much better for the next step of my Spring learning curve. Hoping this helps you also!

I needed a package from github that was written in typscript. I did a git pull of the most recent version from the master branch into the root of my main project. I then went into the directory and did an npm install so that the gulp commands would work that generates ES5 modules. Anyway, to make the long story short, my build process was trying to build files from this new folder so I had to move it out of my root. This was causing these same errors.

We cannot escape if-else ladder in order to compare a string with others. Even regular switch-case is also an if-else ladder (for integers) internally. We might only want to simulate the switch-case for string, but can never replace if-else ladder. The best of the algorithms for string comparison cannot escape from using strcmp function. Means to compare character by character until an unmatch is found. So using if-else ladder and strcmp are inevitable.

DEMO

And here are simplest macros to simulate the switch-case for strings.

#ifndef SWITCH_CASE_INIT
#define SWITCH_CASE_INIT
    #define SWITCH(X)   for (char* __switch_p__ = X, int __switch_next__=1 ; __switch_p__ ; __switch_p__=0, __switch_next__=1) { {
    #define CASE(X)         } if (!__switch_next__ || !(__switch_next__ = strcmp(__switch_p__, X))) {
    #define DEFAULT         } {
    #define END         }}
#endif

And you can use them as

char* str = "def";

SWITCH (str)
    CASE ("abc")
        printf ("in abc\n");
        break;
    CASE ("def")              // Notice: 'break;' statement missing so the control rolls through subsequent CASE's until DEFAULT 
        printf("in def\n");
    CASE ("ghi")
        printf ("in ghi\n");
    DEFAULT
        printf("in DEFAULT\n");
END

Output:

in def
in ghi
in DEFAULT

Below is nested SWITCH usage:

char* str = "def";
char* str1 = "xyz";

SWITCH (str)
    CASE ("abc")
        printf ("in abc\n");
        break;
    CASE ("def")                                
        printf("in def\n");
        SWITCH (str1)                           // <== Notice: Nested SWITCH
            CASE ("uvw")
                printf("in def => uvw\n");
                break;
            CASE ("xyz")
                printf("in def => xyz\n");
                break;
            DEFAULT
                printf("in def => DEFAULT\n");
        END
    CASE ("ghi")
        printf ("in ghi\n");
    DEFAULT
        printf("in DEFAULT\n");
END

Output:

in def
in def => xyz
in ghi
in DEFAULT

Here is reverse string SWITCH, where in you can use a variable (rather than a constant) in CASE clause:

char* str2 = "def";
char* str3 = "ghi";

SWITCH ("ghi")                      // <== Notice: Use of variables and reverse string SWITCH.
    CASE (str1)
        printf ("in str1\n");
        break;
    CASE (str2)                     
        printf ("in str2\n");
        break;
    CASE (str3)                     
        printf ("in str3\n");
        break;
    DEFAULT
        printf("in DEFAULT\n");
END

Output:

in str3

Probably the easiest thing to do would be to give your scrip tag an id attribute.

Another approach to do it..

May it help someone...

if ([[temp substringToIndex:4] isEqualToString:@"http"]) {
  //starts with http
}

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

4. Set your camera of choice as the front/back cameras:

Are you changing the env option?

Then look at this answer.

I was trying to spawn a node process and TIL that you should spread the existing environment variables when you spawn else you'll loose the PATH environment variable and possibly other important ones.

This was the fix for me:

const nodeProcess = spawn('node', ['--help'], {
  env: {
    // by default, spawn uses `process.env` for the value of `env`
    // you can _add_ to this behavior, by spreading `process.env`
    ...process.env,
    OTHER_ENV_VARIABLE: 'test',
  }
});

   var tabSelect = document.location.hash.substr(1, document.location.hash.length);
   console.log("tabSelect: " + tabSelect);
   if (tabSelect == 'discount')
   { 
       var index = $('#myTab a[href="#discount"]').parent().index();
       $("#tabs").tabs("option", "active", index);

}

I know my answer is 7 years late, but here's my suggestion anyway:

When Access complains about an UPDATE query that includes a JOIN, just save the query, with RecordsetType property set to Dynaset (Inconsistent Updates).

This will sometimes allow the UPDATE to work.

Like stated in this question: Git: Create a branch from unstagged/uncommited changes on master: stash is not necessary.

Just use:

git checkout -b topic/newbranch

Any uncommitted work will be taken along to the new branch.

If you try to push you will get the following message

fatal: The current branch feature/NEWBRANCH has no upstream branch. To push the current branch and set the remote as upstream, use

git push --set-upstream origin feature/feature/NEWBRANCH

Just do as suggested to create the branch remotely:

git push --set-upstream origin feature/feature/NEWBRANCH

There is a possibility to split and explode the dataframe without changing the structure of dataframe

Split and expand data of specific columns

Input:

    var1    var2
0   a,b,c   1
1   d,e,f   2



#Get the indexes which are repetative with the split 
df['var1'] = df['var1'].str.split(',')
df = df.explode('var1')

Out:

    var1    var2
0   a   1
0   b   1
0   c   1
1   d   2
1   e   2
1   f   2

Edit-1

Split and Expand of rows for Multiple columns

Filename    RGB                                             RGB_type
0   A   [[0, 1650, 6, 39], [0, 1691, 1, 59], [50, 1402...   [r, g, b]
1   B   [[0, 1423, 16, 38], [0, 1445, 16, 46], [0, 141...   [r, g, b]

Re indexing based on the reference column and aligning the column value information with stack

df = df.reindex(df.index.repeat(df['RGB_type'].apply(len)))
df = df.groupby('Filename').apply(lambda x:x.apply(lambda y: pd.Series(y.iloc[0])))

Combining solutions above when using express request:

let url=url.parse(req.originalUrl);
let page = url.parse(uri).path?url.parse(uri).path.match('^[^?]*')[0].split('/').slice(1)[0] : '';

this will handle all cases like

localhost/page
localhost:3000/page/
/page?item_id=1
localhost:3000/
localhost/

etc. Some examples:

> urls
[ 'http://localhost/page',
  'http://localhost:3000/page/',
  'http://localhost/page?item_id=1',
  'http://localhost/',
  'http://localhost:3000/',
  'http://localhost/',
  'http://localhost:3000/page#item_id=2',
  'http://localhost:3000/page?item_id=2#3',
  'http://localhost',
  'http://localhost:3000' ]
> urls.map(uri => url.parse(uri).path?url.parse(uri).path.match('^[^?]*')[0].split('/').slice(1)[0] : '' )
[ 'page', 'page', 'page', '', '', '', 'page', 'page', '', '' ]

Ah, ok. What you're looking for is setHint(int). Simply pass in a resource id of a string from your xml and you're good to go.

EDIT

And in XML, it's simply android:hint="someText"

NSString * varyingString = ...;
NSString * cat = [NSString stringWithFormat:@"%s%@%@",
  "first part of string",
  varyingString,
  @"third part of string"];

or simply -[NSString stringByAppendingString:]

Try this

-moz-box-shadow:0 5px 5px rgba(182, 182, 182, 0.75);
-webkit-box-shadow: 0 5px 5px rgba(182, 182, 182, 0.75);
box-shadow: 0 5px 5px rgba(182, 182, 182, 0.75);

Thread.sleep() is simple for the beginners and may be appropriate for unit tests and proofs of concept.

But please DO NOT use sleep() for production code. Eventually sleep() may bite you badly.

Best practice for multithreaded/multicore java applications to use the "thread wait" concept. Wait releases all the locks and monitors held by the thread, which allows other threads to acquire those monitors and proceed while your thread is sleeping peacefully.

Code below demonstrates that technique:

import java.util.concurrent.TimeUnit;
public class DelaySample {
    public static void main(String[] args) {
       DelayUtil d = new DelayUtil();
       System.out.println("started:"+ new Date());
       d.delay(500);
       System.out.println("half second after:"+ new Date());
       d.delay(1, TimeUnit.MINUTES); 
       System.out.println("1 minute after:"+ new Date());
    }
}

DelayUtil implementation:

import java.util.concurrent.TimeUnit;
import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.ReentrantLock;

public class DelayUtil {
    /** 
    *  Delays the current thread execution. 
    *  The thread loses ownership of any monitors. 
    *  Quits immediately if the thread is interrupted
    *  
    * @param durationInMillis the time duration in milliseconds
    */
   public void delay(final long durationInMillis) {
      delay(durationInMillis, TimeUnit.MILLISECONDS);
   }

   /** 
    * @param duration the time duration in the given {@code sourceUnit}
    * @param unit
    */
    public void delay(final long duration, final TimeUnit unit) {
        long currentTime = System.currentTimeMillis();
        long deadline = currentTime+unit.toMillis(duration);
        ReentrantLock lock = new ReentrantLock();
        Condition waitCondition = lock.newCondition();

        while ((deadline-currentTime)>0) {
            try {
                lock.lockInterruptibly();    
                waitCondition.await(deadline-currentTime, TimeUnit.MILLISECONDS);
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
                return;
            } finally {
                lock.unlock();
            }
            currentTime = System.currentTimeMillis();
        }
    }
}

I got a easy solution which will select from database table and let you do easily.

SELECT b.FirstName + b.LastName FROM tbl_Users b WHERE b.Id='11'

You can easily add a space there if you try

SELECT b.FirstName +' '+ b.LastName FROM Users b WHERE b.Id='23'

Here you can combine as much as your table have.

thanks S Doerin:

"Just for completion. This error might be as well the case if you have a foreign key with VARCHAR(..) and the charset of the referenced table is different from the table referencing it. e.g. VARCHAR(50) in a Latin1 Table is different than the VARCHAR(50) in a UTF8 Table."

i solved this problem, changing the type of characters of the table. the creation have latin1 and the correct is utf8.

add the next line. DEFAULT CHARACTER SET = utf8;

The following is what I use to commit changes on foo to N=1 days in the past:

git add foo
git commit -m "Update foo"
git commit --amend --date="$(date -v-1d)"

If you want to commit to a even older date, say 3 days back, just change the date argument: date -v-3d.

That's really useful when you forget to commit something yesterday, for instance.

UPDATE: --date also accepts expressions like --date "3 days ago" or even --date "yesterday". So we can reduce it to one line command:

git add foo ; git commit --date "yesterday" -m "Update"

If you're using Python 3, or appropriate Python 2.x version with from __future__ import print_function then:

data = [7, 7, 7, 7]
print(*data, sep='')

Otherwise, you'll need to convert to string and print:

print ''.join(map(str, data))

[BTW, it also appears you are using Tabs. It's common practice to have the IDE turn Tabs into spaces (often 4), via Options.]

May I just leave it here

s = 'foo/bar spam\neggs'
print(s.replace('/', '+++/+++').replace(' ', '+++ +++').replace('\n', '+++\n+++').split('+++'))

['foo', '/', 'bar', ' ', 'spam', '\n', 'eggs']

I experienced this problem too. I discovered the problem is because Oracle DB does not like the space in C:program files (x86)\Toad...... so I created a new directory named C:App\Toad then reinstalled in it to connect Toad to Oracle. It worked.

(Current PowerShell version 5.1.17134.407)

This also works as of now:

$myVar = "Hello"

echo "${myVar} World"

Note: this only works with double quotes

I'm afraid that's not possible. the rgba format you know is the only one.

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

This is a very confusing topic. django stores all applied migrations in a table called django_migrations. perform this sql ( i am using postgres . so in query tool section)

select * from django_migrations where app='your appname'  (app in which u have issue with).

This will list all applied migrations for that app.
Go to your app/migration folder and check all migrations . find the migration file associated with your error . file where your table was created or column added or modified.
look for the id of this migration file in django_migrations table( select * from django_migrations where app='your app') .

Then do :

delete from django_migrations where id='id of your migration';

delete multiple id's if you have multiple migrations file associated with your issue.

now reapply migrate

Python manage.py migrate yourappname

second option

1. Drop tables in your app where you have issue.

2. delete all migrations for that app from app/migrations folder.(don't delete init.py from that folder).

3. now run

   python manage.py makemigrations appname

4. now run

python manage.py migrate appname

This solution works with special characters too, for instance é, è, ê, ü, ö, à

2 steps:

1. Remove the accents, based on this answer: Remove accents/diacritics in a string in JavaScript
2. Check if a to z character, using regex or unicode (your choice)

Live demos of my solution:

1. using global functions
2. using javascript module pattern

Note: I posted the solution that uses global functions as it's probably the simplest to understand. But do look into "javascript module pattern" if you want better code (cleaner, easier to maintain and extend), see impressivewebs.com/my-current-javascript-design-pattern and also this YouTube video (presentation by Paul Irish).

Getting an ECONNREFUSED errno means that your kernel was refused a connection at the other end, so if it's a bug, it's either in your kernel or in the other end. What you can do is to trap the error in a very specific way and try again in a little while, since this seems to work:

# This is Python > 2.5 code
import errno, time

for attempt in range(MAXIMUM_NUMBER_OF_ATTEMPTS):
    try:
        # your urllib call here
    except EnvironmentError as exc: # replace " as " with ", " for Python<2.6
        if exc.errno == errno.ECONNREFUSED:
            time.sleep(A_COUPLE_OF_SECONDS)
        else:
            raise # re-raise otherwise
    else: # we tried, and we had no failure, so
        break
else: # we never broke out of the for loop
    raise RuntimeError("maximum number of unsuccessful attempts reached")

Replace the two all-caps constants with your favourite numbers.

When the workbook first opens, execute this code:

alertTime = Now + TimeValue("00:02:00")
Application.OnTime alertTime, "EventMacro"

Then just have a macro in the workbook called "EventMacro" that will repeat it.

Public Sub EventMacro()
    '... Execute your actions here'
    alertTime = Now + TimeValue("00:02:00")
    Application.OnTime alertTime, "EventMacro"
End Sub

You can get list of all services and select by color one of them with 'grep':

sudo service --status-all | grep postgres

Or you may use another way if you know correct name of service:

sudo service postgresql status

Javascript String objects have a split function, doesn't really need to be jQuery specific

 var str = "nice.test"
 var strs = str.split(".")

strs would be

 ["nice", "test"]

I'd be tempted to use JSON in your example though. The php could return the JSON which could easily be parsed

 success: function(data) {
   var items = JSON.parse(data)
 }

This is pretty much what the generic method Value() is for. You get exactly the behavior you want if you combine it with nullable value types and the ?? operator:

width = jToken.Value<double?>("width") ?? 100;

for word in d:
    if d in paid[j]:
         do_something()

will try all the words in the list d and check if they can be found in the string paid[j].

This is not very efficient since paid[j] has to be scanned again for each word in d. You could also use two sets, one composed of the words in the sentence, one of your list, and then look at the intersection of the sets.

sentence = "words don't come easy"
d = ["come", "together", "easy", "does", "it"]

s1 = set(sentence.split())
s2 = set(d)

print (s1.intersection(s2))

Output:

{'come', 'easy'}

Let's start with this simple state diagram:

We have:

• 4 states (Inactive, Active, Paused, and Exited)
• 5 types of state transitions (Begin Command, End Command, Pause Command, Resume Command, Exit Command).

You can convert this to C# in a handful of ways, such as performing a switch statement on the current state and command, or looking up transitions in a transition table. For this simple state machine, I prefer a transition table, which is very easy to represent using a Dictionary:

using System;
using System.Collections.Generic;

namespace Juliet
{
    public enum ProcessState
    {
        Inactive,
        Active,
        Paused,
        Terminated
    }

    public enum Command
    {
        Begin,
        End,
        Pause,
        Resume,
        Exit
    }

    public class Process
    {
        class StateTransition
        {
            readonly ProcessState CurrentState;
            readonly Command Command;

            public StateTransition(ProcessState currentState, Command command)
            {
                CurrentState = currentState;
                Command = command;
            }

            public override int GetHashCode()
            {
                return 17 + 31 * CurrentState.GetHashCode() + 31 * Command.GetHashCode();
            }

            public override bool Equals(object obj)
            {
                StateTransition other = obj as StateTransition;
                return other != null && this.CurrentState == other.CurrentState && this.Command == other.Command;
            }
        }

        Dictionary<StateTransition, ProcessState> transitions;
        public ProcessState CurrentState { get; private set; }

        public Process()
        {
            CurrentState = ProcessState.Inactive;
            transitions = new Dictionary<StateTransition, ProcessState>
            {
                { new StateTransition(ProcessState.Inactive, Command.Exit), ProcessState.Terminated },
                { new StateTransition(ProcessState.Inactive, Command.Begin), ProcessState.Active },
                { new StateTransition(ProcessState.Active, Command.End), ProcessState.Inactive },
                { new StateTransition(ProcessState.Active, Command.Pause), ProcessState.Paused },
                { new StateTransition(ProcessState.Paused, Command.End), ProcessState.Inactive },
                { new StateTransition(ProcessState.Paused, Command.Resume), ProcessState.Active }
            };
        }

        public ProcessState GetNext(Command command)
        {
            StateTransition transition = new StateTransition(CurrentState, command);
            ProcessState nextState;
            if (!transitions.TryGetValue(transition, out nextState))
                throw new Exception("Invalid transition: " + CurrentState + " -> " + command);
            return nextState;
        }

        public ProcessState MoveNext(Command command)
        {
            CurrentState = GetNext(command);
            return CurrentState;
        }
    }


    public class Program
    {
        static void Main(string[] args)
        {
            Process p = new Process();
            Console.WriteLine("Current State = " + p.CurrentState);
            Console.WriteLine("Command.Begin: Current State = " + p.MoveNext(Command.Begin));
            Console.WriteLine("Command.Pause: Current State = " + p.MoveNext(Command.Pause));
            Console.WriteLine("Command.End: Current State = " + p.MoveNext(Command.End));
            Console.WriteLine("Command.Exit: Current State = " + p.MoveNext(Command.Exit));
            Console.ReadLine();
        }
    }
}

As a matter of personal preference, I like to design my state machines with a GetNext function to return the next state deterministically, and a MoveNext function to mutate the state machine.

I had the same problem. It's true the password is empty, but even so the error message is shown. The solution is just using "sudo" so

$ sudo mysql

will open the mysql tool

For securing the database, you should use sudo again.

$ sudo mysql_secure_installation

What you actually want in this case are the Object.values. Here is a concise ES6 implementation with that in mind:

const add = {
  a: {value:1},
  b: {value:2},
  c: {value:3}
}

const total = Object.values(add).reduce((t, {value}) => t + value, 0)

console.log(total) // 6

or simply:

const add = {
  a: 1,
  b: 2,
  c: 3
}

const total = Object.values(add).reduce((t, n) => t + n)

console.log(total) // 6

SELECT * FROM products WHERE catid IN ('1', '2', '3', '4')

I had the same problem and after reading this topic, I've solved adding this to my CSS:

.navbar-fixed-top {
    z-index: 10000;
}

because in my case, I'm using the fixed top menu.

For some reason, the connection to the server was lost. It could be that the server explicitly closed the connection, or a bug on the server caused it to be closed unexpectedly. Or something between the client and the server (a switch or router) dropped the connection.

It might be server code that caused the problem, and it might not be. If you have access to the server code, you can put some debugging in there to tell you when client connections are closed. That might give you some indication of when and why connections are being dropped.

On the client, you have to write your code to take into account the possibility of the server failing at any time. That's just the way it is: network connections are inherently unreliable.

 <script type="text/Javascript">
        function checkDecimal(inputVal) {
            var ex = /^[0-9]+\.?[0-9]*$/;
            if (ex.test(inputVal.value) == false) {
                inputVal.value = inputVal.value.substring(0, inputVal.value.length - 1);
            }

Use \W which is equivalent to [^a-zA-Z0-9_]. Check the documentation, https://docs.python.org/2/library/re.html

Import re
s =  'h^&ell`.,|o w]{+orld'
replaced_string = re.sub(r'\W+', '*', s)
output: 'h*ell*o*w*orld'

update: This solution will exclude underscore as well. If you want only alphabets and numbers to be excluded, then solution by nneonneo is more appropriate.

I initially avoided turning on logging to monitor PDO because I thought that it would be a hassle but it is not hard at all. You don't need to reboot MySQL (after 5.1.9):

Execute this SQL in phpMyAdmin or any other environment where you may have high db privileges:

SET GLOBAL general_log = 'ON';

In a terminal, tail your log file. Mine was here:

>sudo tail -f /usr/local/mysql/data/myMacComputerName.log

You can search for your mysql files with this terminal command:

>ps auxww|grep [m]ysqld

I found that PDO escapes everything, so you can't write

$dynamicField = 'userName';
$sql = "SELECT * FROM `example` WHERE `:field` = :value";
$this->statement = $this->db->prepare($sql);
$this->statement->bindValue(':field', $dynamicField);
$this->statement->bindValue(':value', 'mick');
$this->statement->execute();

Because it creates:

SELECT * FROM `example` WHERE `'userName'` = 'mick' ;

Which did not create an error, just an empty result. Instead I needed to use

$sql = "SELECT * FROM `example` WHERE `$dynamicField` = :value";

to get

SELECT * FROM `example` WHERE `userName` = 'mick' ;

When you are done execute:

SET GLOBAL general_log = 'OFF';

or else your logs will get huge.

There are multiple ways of applying aggregate functions to multiple columns.

GroupedData class provides a number of methods for the most common functions, including count, max, min, mean and sum, which can be used directly as follows:

• Python:

  df = sqlContext.createDataFrame(
      [(1.0, 0.3, 1.0), (1.0, 0.5, 0.0), (-1.0, 0.6, 0.5), (-1.0, 5.6, 0.2)],
      ("col1", "col2", "col3"))
  
  df.groupBy("col1").sum()
  
  ## +----+---------+-----------------+---------+
  ## |col1|sum(col1)|        sum(col2)|sum(col3)|
  ## +----+---------+-----------------+---------+
  ## | 1.0|      2.0|              0.8|      1.0|
  ## |-1.0|     -2.0|6.199999999999999|      0.7|
  ## +----+---------+-----------------+---------+
  

• Scala

  val df = sc.parallelize(Seq(
    (1.0, 0.3, 1.0), (1.0, 0.5, 0.0),
    (-1.0, 0.6, 0.5), (-1.0, 5.6, 0.2))
  ).toDF("col1", "col2", "col3")
  
  df.groupBy($"col1").min().show
  
  // +----+---------+---------+---------+
  // |col1|min(col1)|min(col2)|min(col3)|
  // +----+---------+---------+---------+
  // | 1.0|      1.0|      0.3|      0.0|
  // |-1.0|     -1.0|      0.6|      0.2|
  // +----+---------+---------+---------+
  

Optionally you can pass a list of columns which should be aggregated

df.groupBy("col1").sum("col2", "col3")

You can also pass dictionary / map with columns a the keys and functions as the values:

• Python

  exprs = {x: "sum" for x in df.columns}
  df.groupBy("col1").agg(exprs).show()
  
  ## +----+---------+
  ## |col1|avg(col3)|
  ## +----+---------+
  ## | 1.0|      0.5|
  ## |-1.0|     0.35|
  ## +----+---------+
  

• Scala

  val exprs = df.columns.map((_ -> "mean")).toMap
  df.groupBy($"col1").agg(exprs).show()
  
  // +----+---------+------------------+---------+
  // |col1|avg(col1)|         avg(col2)|avg(col3)|
  // +----+---------+------------------+---------+
  // | 1.0|      1.0|               0.4|      0.5|
  // |-1.0|     -1.0|3.0999999999999996|     0.35|
  // +----+---------+------------------+---------+
  

Finally you can use varargs:

• Python

  from pyspark.sql.functions import min
  
  exprs = [min(x) for x in df.columns]
  df.groupBy("col1").agg(*exprs).show()
  

• Scala

  import org.apache.spark.sql.functions.sum
  
  val exprs = df.columns.map(sum(_))
  df.groupBy($"col1").agg(exprs.head, exprs.tail: _*)
  

There are some other way to achieve a similar effect but these should more than enough most of the time.

Locate the following file

C:\Users\[your name]\.android\adb_usb.ini

And make the following changes:

# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x2207

I added 0x2207 to the file. This number is part of the hardware id, which can be found under the device's hardware information.

Mine was:

USB\VID_2207&PID_0010&MI_01

(I tried executing android update adb, but it did nothing.)

I assume you know how to get the DOM object for the <a> element (use document.getElementById or some other method).

To add any attribute, just use the setAttribute method on the DOM object:

a = document.getElementById(...);
a.setAttribute("href", "somelink url");

Add below line in ${kafka_home}/config/server.properties

delete.topic.enable=true

Restart the kafka server with new config:

${kafka_home}/bin/kafka-server-start.sh ~/kafka/config/server.properties

Delete the topics you wish to:

${kafka_home}/bin/kafka-topics.sh --delete  --zookeeper localhost:2181  --topic daemon12

The problem is that img tag is inline element and you can't restrict width of inline element.

So to restrict img tag width first you need to convert it into a inline-block element

img.Image{
    display: inline-block;
}

No there is not : But I have created one easy class to help :

public class PropertiesUtility
{
    private static Hashtable ht = new Hashtable();
    public void loadProperties(string path)
    {
        string[] lines = System.IO.File.ReadAllLines(path);
        bool readFlag = false;
        foreach (string line in lines)
        {
            string text = Regex.Replace(line, @"\s+", "");
            readFlag =  checkSyntax(text);
            if (readFlag)
            {
                string[] splitText = text.Split('=');
                ht.Add(splitText[0].ToLower(), splitText[1]);
            }
        }
    }

    private bool checkSyntax(string line)
    {
        if (String.IsNullOrEmpty(line) || line[0].Equals('['))
        {
            return false;
        }

        if (line.Contains("=") && !String.IsNullOrEmpty(line.Split('=')[0]) && !String.IsNullOrEmpty(line.Split('=')[1]))
        {
            return true;
        }
        else
        {
            throw new Exception("Can not Parse Properties file please verify the syntax");
        }
    }

    public string getProperty(string key)
    {
        if (ht.Contains(key))
        {
            return ht[key].ToString();
        }
        else
        {
            throw new Exception("Property:" + key + "Does not exist");
        }

    }
}

Hope this helps.

Seem to Junit jar file is not in path also make sure you are using jdk1.5 or above.

In migration file check the public override void Up() method. May be you are trying to create a new db object which is already in database. So, you need to drop this object/table before creation of the db object. Just do like bellow-

DropTable("dbo.ABC"); 
CreateTable(
            "dbo.ABC",
            c => new
                {
                    Id = c.Int(nullable: false, identity: true),
                    ..
                 }

And now run your migration Update-Database -TargetMigration: "2016_YourMigration"

Just add this to your code Controller

return response()->json(compact('token'))->header("Access-Control-Allow-Origin",  "*");

Install using pip install pycompyle6

pycompyle6 filename.pyc

You'll need to run this command from the MySQL prompt:

REPAIR TABLE tbl_name USE_FRM;

From MySQL's documentation on the Repair command:

The USE_FRM option is available for use if the .MYI index file is missing or if its header is corrupted. This option tells MySQL not to trust the information in the .MYI file header and to re-create it using information from the .frm file. This kind of repair cannot be done with myisamchk.

SQLServer runs the default instance over port 1433. If you specify the port as port 1433, SQLServer will only look for the default instance. The name of the default instance was created at setup and usually is SQLEXPRESSxxx_xx_ENU.

The instance name also matches the folder name created in Program Files -> Microsoft SQL Server. So if you look there and see one folder named SQLEXPRESSxxx_xx_ENU it is the default instance.

Folders named MSSQL12.myInstanceName (for SQLServer 2012) are named instances in SQL Server and are not accessed via port 1433.

So if your program is accessing a default instance in the database, specify port 1433, and you may not need to specify the instance name.

If your program is accessing a named instance (not the default instance) in the database DO NOT specify the port but you must specify the instance name.

I hope this clarifies some of the confusion emanating from the errors above.

In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.

The second BEGIN's SQL statement doesn't have INTO clause and that caused the error.

I have taken @Joel Coehoorn answer and made the changes he adviced - put the variable out of the method and put all in class. Plus now the time is random too. Here is the result.

class RandomDateTime
{
    DateTime start;
    Random gen;
    int range;

    public RandomDateTime()
    {
        start = new DateTime(1995, 1, 1);
        gen = new Random();
        range = (DateTime.Today - start).Days;
    }

    public DateTime Next()
    {
        return start.AddDays(gen.Next(range)).AddHours(gen.Next(0,24)).AddMinutes(gen.Next(0,60)).AddSeconds(gen.Next(0,60));
    }
}

And example how to use to write 100 random DateTimes to console:

RandomDateTime date = new RandomDateTime();
for (int i = 0; i < 100; i++)
{
    Console.WriteLine(date.Next());
}

This doesn't explain why it should be like that, but it explains why it could happen. The following byte-code sets -1 to the internal updateCount flag in the SQLServerStatement constructor:

// Method descriptor #401 (Lcom/microsoft/sqlserver/jdbc/SQLServerConnection;II)V
// Stack: 5, Locals: 8
SQLServerStatement(
  com.microsoft.sqlserver.jdbc.SQLServerConnection arg0, int arg1, int arg2) 
throws com.microsoft.sqlserver.jdbc.SQLServerException;

// [...]

34 aload_0 [this]
35 iconst_m1
36 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

Now, I will not analyse all possible control-flows, but I'd just say that this is the internal default initialisation value that somehow leaks out to client code. Note, this is also done in other methods:

// Method descriptor #383 ()V
// Stack: 2, Locals: 1
final void resetForReexecute() 
throws com.microsoft.sqlserver.jdbc.SQLServerException;

// [...]

10 aload_0 [this]
11 iconst_m1
12 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

// Method descriptor #383 ()V
// Stack: 3, Locals: 3
final void clearLastResult();
0 aload_0 [this]
1 iconst_m1
2 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

In other words, you're probably safe interpreting -1 as being the same as 0. If you rely on this result value, maybe stay on the safe side and do your checks as follows:

// No rows affected
if (stmt.executeUpdate() <= 0) {
}
// Rows affected
else {
}

UPDATE: While reading Mark Rotteveel's answer, I tend to agree with him, assuming that -1 is the JDBC-compliant value for "unknown update counts". Even if this isn't documented on the relevant method's Javadoc, it's documented in the JDBC specs, chapter 13.1.2.3 Returning Unknown or Multiple Results. In this very case, it could be said that an IF .. INSERT .. statement will have an "unknown update count", as this statement isn't SQL-standard compliant anyway.

There are a few more differences regarding the structure you could mention.

1. Both DLL and EXE share the same file structure - Portable Executable, or PE. To differentiate between the two, one can look in the Characteristics member of IMAGE_FILE_HEADER inside IMAGE_NT_HEADERS. For a DLL, it has the IMAGE_FILE_DLL (0x2000) flag turned on. For a EXE it's the IMAGE_FILE_EXECUTABLE_IMAGE (0x2) flag.
2. PE files consist of some headers and a number of sections. There's usually a section for code, a section for data, a section listing imported functions and a section for resources. Some sections may contain more than one thing. The header also describes a list of data directories that are located in the sections. Those data directories are what enables Windows to find what it needs in the PE. But one type of data directory that an EXE will never have (unless you're building a frankenstein EXE) is the export directory. This is where DLL files have a list of functions they export and can be used by other EXE or DLL files. On the other side, each DLL and EXE has an import directory where it lists the functions and DLL files it requires to run.
3. Also in the PE headers (IMAGE_OPTIONAL_HEADER) is the ImageBase member. It specifies the virtual address at which the PE assumes it will be loaded. If it is loaded at another address, some pointers could point to the wrong memory. As EXE files are amongst the first to be loaded into their new address space, the Windows loader can assure a constant load address and that's usually 0x00400000. That luxury doesn't exist for a DLL. Two DLL files loaded into the same process can request the same address. This is why a DLL has another data directory called Base Relocation Directory that usually resides in its own section - .reloc. This directory contains a list of places in the DLL that need to be rebased/patched so they'll point to the right memory. Most EXE files don't have this directory, but some old compilers do generate them.

You can read more on this topic @ MSDN.

Assuming ASCII strings:

string1 = 'Hello'
string2 = 'hello'

if string1.lower() == string2.lower():
    print("The strings are the same (case insensitive)")
else:
    print("The strings are NOT the same (case insensitive)")

dom event delegation is something different from the computer science definition.

It refers to handling bubbling events from many elements, like table cells, from a parent object, like the table. It can keep the code simpler, especially when adding or removing elements, and saves some memory.

The steps you took are not appropriate because the cell you want formatted is not the trigger cell (presumably won't normally be blank). In your case you want formatting to apply to one set of cells according to the status of various other cells. I suggest with data layout as shown in the image (and with thanks to @xQbert for a start on a suitable formula) you select ColumnA and:

HOME > Styles - Conditional Formatting, New Rule..., Use a formula to determine which cells to format and Format values where this formula is true::

=AND(LEN(E1)*LEN(F1)*LEN(G1)*LEN(H1)=0,NOT(ISBLANK(A1)))

Format..., select formatting, OK, OK.

where I have filled yellow the cells that are triggering the red fill result.

The question is really about scope, as the other guy put it.

In short, consider this "module":

You can check out this MSDN reference for more on variable declaration and this other Stack Overflow Question for more on how variables go out of scope.

Two other quick things:

1. Be organized when using workbook level variables, so your code doesn't get confusing. Prefer Functions (with proper data types) or passing arguments ByRef.
2. If you want a variable to preserve its value between calls, you can use the Static statement.

How about this?

 "1,112".delete(',').to_i

For such a seemingly simple thing this can be a royal pain in the butt! I found a solution that works beautifully (class="video-close" is obviously particular to this button and optional)

 <a href="javascript:window.open('','_self').close();" class="video-close">Close this window</a>

You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t below) and alias the columns as well.

The DISTINCT can also be safely removed as the internal GROUP BY makes it redundant:

SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
    SELECT MIN(`date`) AS `date`, `player_name`
    FROM `player_playtime`
    GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;

Since the COUNT is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*) and further simplify the query:

SELECT t.date , COUNT(*) AS player_count
FROM (
    SELECT DATE(MIN(`date`)) AS date
    FROM player_playtime
    GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;

Use lxml.builder class, from: http://lxml.de/tutorial.html#the-e-factory

import lxml.builder as lb
from lxml import etree

nstext = "new story"
story = lb.E.Asset(
  lb.E.Attribute(nstext, name="Name", act="set"),
  lb.E.Relation(lb.E.Asset(idref="Scope:767"),
            name="Scope", act="set")
  )

print 'story:\n', etree.tostring(story, pretty_print=True)

Output:

story:
<Asset>
  <Attribute name="Name" act="set">new story</Attribute>
  <Relation name="Scope" act="set">
    <Asset idref="Scope:767"/>
  </Relation>
</Asset>

Using codecs.open as Alex Martelli suggested proved to be useful to me.

import codecs

delimiter = ';'
reader = codecs.open("your_filename.csv", 'r', encoding='utf-8')
for line in reader:
    row = line.split(delimiter)
    # do something with your row ...

You have to calculate the total of grades If it is SQL 2005 you can use CTE

    WITH Tot(Total) (
    SELECT COUNT(*) FROM table
    )
    SELECT Grade, COUNT(*) / Total * 100
--, CONVERT(VARCHAR, COUNT(*) / Total * 100) + '%'  -- With percentage sign
--, CONVERT(VARCHAR, ROUND(COUNT(*) / Total * 100, -2)) + '%'  -- With Round
    FROM table
    GROUP BY Grade

I also added

.modal { position: absolute; }

to the stylesheet to allow the dialog to scroll, but if the user has moved down to the bottom of a long page the modal can end up hidden off the top of the visible area.

I understand this is no longer an issue in bootstrap 3, but looking for a relatively quick fix until we upgrade I ended up with the above plus calling the following before opening the modal

$('.modal').css('top', $(document).scrollTop() + 50);

Seems to be happy in FireFox, Chrome, IE10 8 & 7 (the browsers I had to hand)

Why reinvent the wheel, use the Threading and the Timer class.

    protected void Application_Start()
    {
        Thread thread = new Thread(new ThreadStart(ThreadFunc));
        thread.IsBackground = true;
        thread.Name = "ThreadFunc";
        thread.Start();
    }

    protected void ThreadFunc()
    {
        System.Timers.Timer t = new System.Timers.Timer();
        t.Elapsed += new System.Timers.ElapsedEventHandler(TimerWorker);
        t.Interval = 10000;
        t.Enabled = true;
        t.AutoReset = true;
        t.Start();
    }

    protected void TimerWorker(object sender, System.Timers.ElapsedEventArgs e)
    {
        //work args
    }

You can use DECIMAL or NUMERIC both are same

The DECIMAL and NUMERIC types store exact numeric data values. These types are used when it is important to preserve exact precision, for example with monetary data. In MySQL, NUMERIC is implemented as DECIMAL, so the following remarks about DECIMAL apply equally to NUMERIC. : MySQL

i.e. DECIMAL(10,2)

Good read

It could be some other line as well. PHP is not always that exact.

Probably you are just missing a semicolon on previous line.

How to reproduce this error, put this in a file called a.php:

<?php
  $a = 5
  $b = 7;        // Error happens here.
  print $b;
?>

Run it:

eric@dev ~ $ php a.php

PHP Parse error:  syntax error, unexpected T_VARIABLE in
/home/el/code/a.php on line 3

Explanation:

The PHP parser converts your program to a series of tokens. A T_VARIABLE is a Token of type VARIABLE. When the parser processes tokens, it tries to make sense of them, and throws errors if it receives a variable where none is allowed.

In the simple case above with variable $b, the parser tried to process this:

$a = 5 $b = 7;

The PHP parser looks at the $b after the 5 and says "that is unexpected".

a = a.split("\n");

Note that splitting returns the new array, rather than just assigning it to the original string. You need to explicitly store it in a variable.

The cc and cxx is located inside /Applications/Xcode.app. This should find the right paths

export CXX=`xcrun -find c++`
export CC=`xcrun -find cc`

It is so simple,you can use following method to do this kind of work:-

-(BOOL)isPoint:(CGPoint)point insideOfRect:(CGRect)rect
{
    if ( CGRectContainsPoint(rect,point))
        return  YES;// inside
    else
        return  NO;// outside
}

In your case,you can pass imagView.center as point and another imagView.frame as rect in about method.

You can also use this method in bellow UITouch Method :

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
}

Here is the what I have done to avoid CrossThreadException and writing to the textbox from another thread.

Here is my Button.Click function- I want to generate a random number of threads and then get their IDs by calling the getID() method and the TextBox value while being in that worker thread.

private void btnAppend_Click(object sender, EventArgs e) 
{
    Random n = new Random();

    for (int i = 0; i < n.Next(1,5); i++)
    {
        label2.Text = "UI Id" + ((Thread.CurrentThread.ManagedThreadId).ToString());
        Thread t = new Thread(getId);
        t.Start();
    }
}

Here is getId (workerThread) code:

public void getId()
{
    int id = Thread.CurrentThread.ManagedThreadId;
    //Note that, I have collected threadId just before calling this.Invoke
    //method else it would be same as of UI thread inside the below code block 
    this.Invoke((MethodInvoker)delegate ()
    {
        inpTxt.Text += "My id is" +"--"+id+Environment.NewLine; 
    });
}

Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount() in a React class.

For you edit, you may want to try something like this:

class Component extends React.Component {
  constructor(props) {
    super(props);
    this.onAddBucket = this.onAddBucket.bind(this);
  }
  componentWillMount() {
    this.setState({
      buckets: {},
    })
  }
  componentDidMount() {
    this.onAddBucket();
  }
  onAddBucket() {
    let self = this;
    let getToken = localStorage.getItem('myToken');
    var apiBaseUrl = "...";
    let input = {
      "name" :  this.state.fields["bucket_name"]
    }
    axios.defaults.headers.common['Authorization'] = getToken;
    axios.post(apiBaseUrl+'...',input)
    .then(function (response) {
      if (response.data.status == 200) {
        this.setState({
          buckets: this.state.buckets.concat(response.data.buckets),
        });
      } else {
        alert(response.data.message);
      }
    })
    .catch(function (error) {
      console.log(error);
    });
  }
  render() {
    return (
      {this.state.bucket}
    );
  }
}

In 'array' world we can look on indexes as some kind of keys. What is surprising the in operator (which is good choice for object) also works with arrays. The returned value for non-existed key is undefined

let arr = ["a","b","c"]; // we have indexes: 0,1,2_x000D_
delete arr[1];           // set 'empty' at index 1_x000D_
arr.pop();               // remove last item_x000D_
_x000D_
console.log(0 in arr,  arr[0]);_x000D_
console.log(1 in arr,  arr[1]);_x000D_
console.log(2 in arr,  arr[2]);

With GNU Make, you can use shell and eval to store, run, and assign output from arbitrary command line invocations. The difference between the example below and those which use := is the := assignment happens once (when it is encountered) and for all. Recursively expanded variables set with = are a bit more "lazy"; references to other variables remain until the variable itself is referenced, and the subsequent recursive expansion takes place each time the variable is referenced, which is desirable for making "consistent, callable, snippets". See the manual on setting variables for more info.

# Generate a random number.
# This is not run initially.
GENERATE_ID = $(shell od -vAn -N2 -tu2 < /dev/urandom)

# Generate a random number, and assign it to MY_ID
# This is not run initially.
SET_ID = $(eval MY_ID=$(GENERATE_ID))

# You can use .PHONY to tell make that we aren't building a target output file
.PHONY: mytarget
mytarget:
# This is empty when we begin
    @echo $(MY_ID)
# This recursively expands SET_ID, which calls the shell command and sets MY_ID
    $(SET_ID)
# This will now be a random number
    @echo $(MY_ID)
# Recursively expand SET_ID again, which calls the shell command (again) and sets MY_ID (again)
    $(SET_ID)
# This will now be a different random number
    @echo $(MY_ID)

$product->get_categories() is deprecated since version 3.0! Use wc_get_product_category_list instead.

https://docs.woocommerce.com/wc-apidocs/function-wc_get_product_category_list.html

The == operator is a simple comparison of values.
For object references the (values) are the (references). So x == y returns true if x and y reference the same object.

I was also wondering about print order. Consider this case, for example:

For a priority queue:

PriorityQueue<String> pq3 = new PriorityQueue<String>();

This code:

pq3.offer("a");
pq3.offer("A");

may print differently than:

String[] sa = {"a", "A"}; 
for(String s : sa)   
   pq3.offer(s);

I found the answer from a discussion on another forum, where a user said, "the offer()/add() methods only insert the element into the queue. If you want a predictable order you should use peek/poll which return the head of the queue."

Starting from Python 3.1, you can use importlib :

import importlib  
foobar = importlib.import_module("foo-bar")

( https://docs.python.org/3/library/importlib.html )

That's a good problem. In order to solve that problem you will also have to disable ASLR otherwise the address of g() will be unpredictable.

Disable ASLR:

sudo bash -c 'echo 0 > /proc/sys/kernel/randomize_va_space'

Disable canaries:

gcc overflow.c -o overflow -fno-stack-protector

After canaries and ASLR are disabled it should be a straight forward attack like the ones described in Smashing the Stack for Fun and Profit

Here is a list of security features used in ubuntu: https://wiki.ubuntu.com/Security/Features You don't have to worry about NX bits, the address of g() will always be in a executable region of memory because it is within the TEXT memory segment. NX bits only come into play if you are trying to execute shellcode on the stack or heap, which is not required for this assignment.

Now go and clobber that EIP!

Something like this?

public static T ConvertValue<T>(string value)
{
    return (T)Convert.ChangeType(value, typeof(T));
}

You can then use it like this:

int val = ConvertValue<int>("42");

Edit:

You can even do this more generic and not rely on a string parameter provided the type U implements IConvertible - this means you have to specify two type parameters though:

public static T ConvertValue<T,U>(U value) where U : IConvertible
{
    return (T)Convert.ChangeType(value, typeof(T));
}

I considered catching the InvalidCastException exception that might be raised by Convert.ChangeType() - but what would you return in this case? default(T)? It seems more appropriate having the caller deal with the exception.

This did the trick for me:

echo trim($entry->title);

As per java documentation definition of Thread.sleep is :

Thread.sleep(t);
where t => time in millisecons to sleep

If you want to sleep for 1 second you should have :

Thread.sleep(1000);

I think requests.head instead of requests.get will be more safe to call when handling url redirect,check the github issue here:

r = requests.head(url, allow_redirects=True)
print(r.url)

A pointer to void is a "generic" pointer type. A void * can be converted to any other pointer type without an explicit cast. You cannot dereference a void * or do pointer arithmetic with it; you must convert it to a pointer to a complete data type first.

void * is often used in places where you need to be able to work with different pointer types in the same code. One commonly cited example is the library function qsort:

void qsort(void *base, size_t nmemb, size_t size, 
           int (*compar)(const void *, const void *));

base is the address of an array, nmemb is the number of elements in the array, size is the size of each element, and compar is a pointer to a function that compares two elements of the array. It gets called like so:

int iArr[10];
double dArr[30];
long lArr[50];
...
qsort(iArr, sizeof iArr/sizeof iArr[0], sizeof iArr[0], compareInt);
qsort(dArr, sizeof dArr/sizeof dArr[0], sizeof dArr[0], compareDouble);
qsort(lArr, sizeof lArr/sizeof lArr[0], sizeof lArr[0], compareLong);

The array expressions iArr, dArr, and lArr are implicitly converted from array types to pointer types in the function call, and each is implicitly converted from "pointer to int/double/long" to "pointer to void".

The comparison functions would look something like:

int compareInt(const void *lhs, const void *rhs)
{
  const int *x = lhs;  // convert void * to int * by assignment
  const int *y = rhs;

  if (*x > *y) return 1;
  if (*x == *y) return 0;
  return -1;
}

By accepting void *, qsort can work with arrays of any type.

The disadvantage of using void * is that you throw type safety out the window and into oncoming traffic. There's nothing to protect you from using the wrong comparison routine:

qsort(dArr, sizeof dArr/sizeof dArr[0], sizeof dArr[0], compareInt);

compareInt is expecting its arguments to be pointing to ints, but is actually working with doubles. There's no way to catch this problem at compile time; you'll just wind up with a missorted array.

Go to your settings.json file, add the following and, fix the eslint.nodepath. Tailor it to your own preferences.

 // PERSONAL
  "editor.codeActionsOnSaveTimeout": 2000,

It can be like this

or

Best is to install it using rvm(ruby version manager).
Run following commands in a terminal:

sudo apt-get update
sudo apt-get install build-essential make curl
\curl -L https://get.rvm.io | bash -s stable
source ~/.bash_profile
rvm install ruby-2.1.4

Then check ruby versions installed and in use:

rvm list
rvm use --default ruby-2.1.4

Also you can directly add ruby bin path to PATH variable. Ruby is installed in

$HOME/.rvm/rubies export PATH=$PATH:$HOME/.rvm/rubies/ruby-2.1.4/bin

If someone need the same in Xamarin (Xamarin.ios / Monotouch), this worked for me:

var myDelegate = UIApplication.SharedApplication.Delegate as AppDelegate;

(Require using UIKit;)

List.clear would remove the elements without reducing the capacity of the list.

groovy:000> mylist = [1,2,3,4,5,6,7,8,9,10,11,12]
===> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
groovy:000> mylist.elementData.length
===> 12
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@19d6af
groovy:000> mylist.clear()
===> null
groovy:000> mylist.elementData.length
===> 12
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@19d6af
groovy:000> mylist = new ArrayList();
===> []
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@2bfdff
groovy:000> mylist.elementData.length
===> 10

Here mylist got cleared, the references to the elements held by it got nulled out, but it keeps the same backing array. Then mylist was reinitialized and got a new backing array, the old one got GCed. So one way holds onto memory, the other one throws out its memory and gets reallocated from scratch (with the default capacity). Which is better depends on whether you want to reduce garbage-collection churn or minimize the current amount of unused memory. Whether the list sticks around long enough to be moved out of Eden might be a factor in deciding which is faster (because that might make garbage-collecting it more expensive).

Yep, just add parenthesis (calling the function). Make sure the function is in scope and actually returns something.

Use format string

intNum = 123
print "0x%x"%(intNum)

or hex function.

intNum = 123
print hex(intNum)

Or using regular expressions

"rmlike" <- function(...) {
  names <- sapply(
    match.call(expand.dots = FALSE)$..., as.character)
  names = paste(names,collapse="|")
  Vars <- ls(1)
  r <- Vars[grep(paste("^(",names,").*",sep=""),Vars)]
  rm(list=r,pos=1)
}

rmlike(temp)

What does this record marking mean? If this is used only for logging purposes, I would use GET and disable all caching, since you want to log every query for this resources. If record marking has another purpose, POST is the way to go. User should know, that his actions effect the system and POST method is a warning.

Don’t Repeat Your CSS

OR

Programs that prompt for passwords usually set the tty into "raw" mode, and read input directly from the tty. If you spawn the subprocess in a pty you can make that work. That is what Expect does...

Try this: use "%40" in place of the "@"

$order = new WC_Order( $post_id ); 

If you

echo $order->id;

then you'll be returned the id of the post from which the order is made. As you've already got that, it's probably not what you want.

echo $order->get_order_number();

will return the id of the order (with a # in front of it). To get rid of the #,

echo trim( str_replace( '#', '', $order->get_order_number() ) );

as per the accepted answer.

As described above I executed:

sc delete ServiceName

However this didn't work as I was executing it from PowerShell.

When using PowerShell you must specify the full path to sc.exe because PowerShell has a default alias for sc assigning it to Set-Content. Since it's a valid command it doesn't actually show an error message.

To resolve this I executed it as follows:

C:\Windows\System32\sc.exe delete ServiceName

Write it however you want, but it's faster to iterate directly over the list, than to generate pairs() or ipairs()

#! /usr/bin/env lua

local items = { 'apple', 'orange', 'pear', 'banana' }

local function locate( table, value )
    for i = 1, #table do
        if table[i] == value then print( value ..' found' ) return true end
    end
    print( value ..' not found' ) return false
end

locate( items, 'orange' )
locate( items, 'car' )

orange found
car not found

To add a file/folder to the project, a good way is:

First of all add your files to /path/to/your/project/my/added/files, and then run following commands:

svn cleanup  /path/to/your/project

svn add --force /path/to/your/project/*

svn cleanup  /path/to/your/project

svn commit /path/to/your/project  -m 'Adding a file'

I used cleanup to prevent any segmentation fault (core dumped), and now the SVN project is updated.

In Python2, input is evaluated, input() is equivalent to eval(raw_input()). When you enter klj, Python tries to evaluate that name and raises an error because that name is not defined.

Use raw_input to get a string from the user in Python2.

Demo 1: klj is not defined:

>>> input()
klj
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'klj' is not defined

Demo 2: klj is defined:

>>> klj = 'hi'
>>> input()
klj
'hi'

Demo 3: getting a string with raw_input:

>>> raw_input()
klj
'klj'

The best place to understand the difference is at the official documentation on values / values_list. It has many useful examples and explains it very clearly. The django docs are very user freindly.

Here's a short snippet to keep SO reviewers happy:

values

Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable.

And read the section which follows it:

value_list

This is similar to values() except that instead of returning dictionaries, it returns tuples when iterated over.

Select 4th option

$('#select').val($('#select option').eq(3).val());

The .bash_profile for macOS is found in the $HOME directory. You can create the file if it does not exit. Sublime Text 3 can help.

• If you follow the instruction from OS X Command Line - Sublime Text to launch ST3 with subl then you can just do this

  $ subl ~/.bash_profile
  

• An easier method is to use open

  $ open ~/.bash_profile -a "Sublime Text"
  

Use Command + Shift + . in Finder to view hidden files in your home directory.

a = np.array([1,2,3])
b = np.array([4,5,6])
np.array((a,b))

works just as well as

np.array([[1,2,3], [4,5,6]])

Regardless of whether it is a list of lists or a list of 1d arrays, np.array tries to create a 2d array.

But it's also a good idea to understand how np.concatenate and its family of stack functions work. In this context concatenate needs a list of 2d arrays (or any anything that np.array will turn into a 2d array) as inputs.

np.vstack first loops though the inputs making sure they are at least 2d, then does concatenate. Functionally it's the same as expanding the dimensions of the arrays yourself.

np.stack is a new function that joins the arrays on a new dimension. Default behaves just like np.array.

Look at the code for these functions. If written in Python you can learn quite a bit. For vstack:

return _nx.concatenate([atleast_2d(_m) for _m in tup], 0)

git config user.name

No need for javascript, just wrap it in a link

<a href="http://www.google.com"><button type="button">button</button></a>

For shorter JavaScript-Code use this:

myApp.service('userService', [
  '$q', function($q) {
    this.initialized = $q.when();
    this.user = {
      access: false
    };
    this.isAuthenticated = function() {
      this.user = {
        first_name: 'First',
        last_name: 'Last',
        email: '[email protected]',
        access: 'institution'
      };
      return this.initialized;
    };
  }
]);

You know that you loose the binding to userService.user by overwriting it with a new object instead of setting only the objects properties?

Here is what I mean as a example of my plnkr.co example code (Working example: http://plnkr.co/edit/zXVcmRKT1TmiBCDL4GsC?p=preview):

angular.module('myApp', []).service('userService', [
    '$http', '$q', '$rootScope', '$location', function ($http, $q, $rootScope, $location) {

Assume you don't have a file named * into /any/dir/you/check, it should work on bash dash posh busybox sh and zsh but (for zsh) require unsetopt nomatch.

Performances should be comparable to any ls which use *(glob), I guess will be slow on directories with many nodes (my /usr/bin with 3000+ files went not that slow), will use at least memory enough to allocate all dirs/filenames (and more) as they are all passed (resolved) to the function as arguments, some shell probably have limits on number of arguments and/or length of arguments.

A portable fast O(1) zero resources way to check if a directory is empty would be nice to have.

update

The version above doesn't account for hidden files/dirs, in case some more test is required, like the is_empty from Rich’s sh (POSIX shell) tricks:

is_empty () (
cd "$1"
set -- .[!.]* ; test -f "$1" && return 1
set -- ..?* ; test -f "$1" && return 1
set -- * ; test -f "$1" && return 1
return 0 )

But, instead, I'm thinking about something like this:

dir_is_empty() {
    [ "$(find "$1" -name "?*" | dd bs=$((${#1}+3)) count=1 2>/dev/null)" = "$1" ]
}

Some concern about trailing slashes differences from the argument and the find output when the dir is empty, and trailing newlines (but this should be easy to handle), sadly on my busybox sh show what is probably a bug on the find -> dd pipe with the output truncated randomically (if I used cat the output is always the same, seems to be dd with the argument count).

In order to compare two files in the git bash you need to use the command:

git diff <Branch name>..master -- Filename.extension   

This command will show the difference between the two files in the bash itself.

After adding the data to the grid add the following code which will adjust the column according to the length of data in each cell

dataGrid1.AutoResizeColumns();            
dataGrid1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;

Here is the Result

Note: you should use the accepted answer if possible. It's better than mine.

It's quite easy with the GD library.

It's built in usually, you probably have it (use phpinfo() to check)

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");

imagejpeg($image, "folder/file.jpg");

The above answer is better (faster) for most situations, but with GD you can also modify it in some form (cropping for example).

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagecopy($image, $image, 0, 140, 0, 0, imagesx($image), imagesy($image));
imagejpeg($image, "folder/file.jpg");

This only works if allow_url_fopen is true (it is by default)

I've been using this function for a while. Removes pretty much any messy html you can throw at it and leaves the text intact.

        private static readonly Regex _tags_ = new Regex(@"<[^>]+?>", RegexOptions.Multiline | RegexOptions.Compiled);

        //add characters that are should not be removed to this regex

            html = RemoveTag(html, "<script", "</script>");
            html = RemoveTag(html, "<style", "</style>");

            //replace matches of these regexes with space
            html = _tags_.Replace(html, " ");

            foreach (Char c in inString)
            {
                switch (c)
                {
                    case '\r':
                    case '\n':

                        if (!inBlanks)
                        {
                            inBlanks = true;
                            sb.Append(' ');
                        }   
                        continue;
                    default:
                        inBlanks = false;
                        sb.Append(c);
                        break;
                }
            }
            return sb.ToString().Trim();
        }

The standard implementation is weak and using it leads to unnecessary collisions. Imagine a

class ListPair {
    List<Integer> first;
    List<Integer> second;

    ListPair(List<Integer> first, List<Integer> second) {
        this.first = first;
        this.second = second;
    }

    public int hashCode() {
        return Objects.hashCode(first, second);
    }

    ...
}

Now,

new ListPair(List.of(a), List.of(b, c))

and

new ListPair(List.of(b), List.of(a, c))

have the same hashCode, namely 31*(a+b) + c as the multiplier used for List.hashCode gets reused here. Obviously, collisions are unavoidable, but producing needless collisions is just... needless.

There's nothing substantially smart about using 31. The multiplier must be odd in order to avoid losing information (any even multiplier loses at least the most significant bit, multiples of four lose two, etc.). Any odd multiplier is usable. Small multipliers may lead to faster computation (the JIT can use shifts and additions), but given that multiplication has latency of only three cycles on modern Intel/AMD, this hardly matters. Small multipliers also leads to more collision for small inputs, which may be a problem sometimes.

Using a prime is pointless as primes have no meaning in the ring Z/(2**32).

So, I'd recommend using a randomly chosen big odd number (feel free to take a prime). As i86/amd64 CPUs can use a shorter instruction for operands fitting in a single signed byte, there is a tiny speed advantage for multipliers like 109. For minimizing collisions, take something like 0x58a54cf5.

Using different multipliers in different places is helpful, but probably not enough to justify the additional work.

Math.sqrt returns a double so you'll have to cast it to int as well

distance = (int)Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2));

This is the only comprehensive and reliable way I've found to do this.

Assume you want to merge "tag_1.0" into "mybranch".

    $git checkout tag_1.0 (will create a headless branch)
    $git branch -D tagbranch (make sure this branch doesn't already exist locally)
    $git checkout -b tagbranch
    $git merge -s ours mybranch
    $git commit -am "updated mybranch with tag_1.0"
    $git checkout mybranch
    $git merge tagbranch

Simply add these to your ggplot:

+ scale_x_continuous(expand = c(0, 0), limits = c(0, NA)) + 
  scale_y_continuous(expand = c(0, 0), limits = c(0, NA))

Example

df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for


p + scale_x_continuous(expand = c(0, 0), limits = c(0,NA)) + 
  scale_y_continuous(expand = c(0, 0), limits = c(0, NA))

Lastly, take great care not to unintentionally exclude data off your chart. For example, a position = 'dodge' could cause a bar to get left off the chart entirely (e.g. if its value is zero and you start the axis at zero), so you may not see it and may not even know it's there. I recommend plotting data in full first, inspect, then use the above tip to improve the plot's aesthetics.

Or you can simply use OleDbDataAdapter to get data from Excel

Yes, this can be scripted with VBScript. For example the following code can create a zip from a directory:

Dim fso, winShell, MyTarget, MySource, file
Set fso = CreateObject("Scripting.FileSystemObject")
Set winShell = createObject("shell.application")


MyTarget = Wscript.Arguments.Item(0)
MySource = Wscript.Arguments.Item(1)

Wscript.Echo "Adding " & MySource & " to " & MyTarget

'create a new clean zip archive
Set file = fso.CreateTextFile(MyTarget, True)
file.write("PK" & chr(5) & chr(6) & string(18,chr(0)))
file.close

winShell.NameSpace(MyTarget).CopyHere winShell.NameSpace(MySource).Items

do until winShell.namespace(MyTarget).items.count = winShell.namespace(MySource).items.count
    wscript.sleep 1000 
loop

Set winShell = Nothing
Set fso = Nothing

You may also find http://www.naterice.com/blog/template_permalink.asp?id=64 helpful as it includes a full Unzip/Zip implementation in VBScript.

If you do a size check every 500 ms rather than a item count it works better for large files. Win 7 writes the file instantly although it's not finished compressing:

set fso=createobject("scripting.filesystemobject")
Set h=fso.getFile(DestZip)
do
    wscript.sleep 500
    max = h.size
loop while h.size > max 

Works great for huge amounts of log files.

You can accomplish this by preventing the keyPress event from occurring for non-numeric values

e.g (using jQuery)

$('.input-selector').on('keypress', function(e){
  return e.metaKey || // cmd/ctrl
    e.which <= 0 || // arrow keys
    e.which == 8 || // delete key
    /[0-9]/.test(String.fromCharCode(e.which)); // numbers
})

This accounts for all different types of input (e.g. input from the number pad has different codes than the keyboard) as well as backspace, arrow keys, control/cmd + r to reload etc

It's working for me:

DependencyObject GetTopLevelControl(DependencyObject control)
{
    DependencyObject tmp = control;
    DependencyObject parent = null;
    while((tmp = VisualTreeHelper.GetParent(tmp)) != null)
    {
        parent = tmp;
    }
    return parent;
}

Use the Figure.savefig() method, like so:

ax = s.hist()  # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')

It doesn't have to end in pdf, there are many options. Check out the documentation.

Alternatively, you can use the pyplot interface and just call the savefig as a function to save the most recently created figure:

import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf')  # saves the current figure

You can use COPY. You need to specify the directory explicitly. It won't be created by itself

COPY go /usr/local/go

Why not just create a bean that starts your monitor on initialization, something like:

@Component
public class Monitor {
    @Autowired private SomeService service

    @PostConstruct
    public void init(){
        // start your monitoring in here
    }
}

the init method will not be called until any autowiring is done for the bean.

CSS
select{
  color:red;
 }

HTML
<select id="sel" onclick="document.getElementById('sel').style.color='green';">
 <option>Select Your Option</option>
 <option value="">INDIA</option>
 <option value="">USA</option>
</select>

The above code will change the colour of text on click of the select box.

and if you want every option different colour, give separate class or id to all options.

Doing the same in declarative pipeline syntax, below are few examples:

stage('master-branch-stuff') {
    when {
        branch 'master'
    }
    steps {
        echo 'run this stage - ony if the branch = master branch'
    }
}

stage('feature-branch-stuff') {
    when {
        branch 'feature/*'
    }
    steps {
        echo 'run this stage - only if the branch name started with feature/'
    }
}

stage('expression-branch') {
    when {
        expression {
            return env.BRANCH_NAME != 'master';
        }
    }
    steps {
        echo 'run this stage - when branch is not equal to master'
    }
}

stage('env-specific-stuff') {
    when { 
        environment name: 'NAME', value: 'this' 
    }
    steps {
        echo 'run this stage - only if the env name and value matches'
    }
}

equals - Compares two values - strings, variables, numbers, booleans - and returns true if they’re equal. I’m honestly not sure how we missed adding this earlier! You can do "not equals" comparisons using the not { equals ... } combination too.

changeRequest - In its simplest form, this will return true if this Pipeline is building a change request, such as a GitHub pull request. You can also do more detailed checks against the change request, allowing you to ask "is this a change request against the master branch?" and much more.

buildingTag - A simple condition that just checks if the Pipeline is running against a tag in SCM, rather than a branch or a specific commit reference.

tag - A more detailed equivalent of buildingTag, allowing you to check against the tag name itself.

Here is the syntax using jQuery $.get

$.get(url, data, successCallback, datatype)

So in your case, that would equate to,

var url = 'ajax.asp';
var data = { ajaxid: 4, UserID: UserID, EmailAddress: EmailAddress };
var datatype = 'jsonp';

function success(response) {
// do something here 
}

$.get('ajax.aspx', data, success, datatype)

Note $.get does not give you the opportunity to set an error handler. But there are several ways to do it either using $.ajaxSetup(), $.ajaxError() or chaining a .fail on your $.get like below

$.get(url, data, success, datatype)
 .fail(function(){
})

The reason for setting the datatype as 'jsonp' is due to browser same origin policy issues, but if you are making the request on the same domain where your javascript is hosted, you should be fine with datatype set to json.

If you don't want to use the jquery $.get then see the docs for $.ajax which allows room for more flexibility

If you do decide to have MySQL handle the update of timestamps, you can set up a trigger to update the field on insert.

CREATE TRIGGER <trigger_name> BEFORE INSERT ON <table_name> FOR EACH ROW SET NEW.<timestamp_field> = CURRENT_TIMESTAMP;

MySQL Reference: http://dev.mysql.com/doc/refman/5.0/en/triggers.html

You can reset the index using reset_index to get back a default index of 0, 1, 2, ..., n-1 (and use drop=True to indicate you want to drop the existing index instead of adding it as an additional column to your dataframe):

In [19]: df2 = df2.reset_index(drop=True)

In [20]: df2
Out[20]:
   x  y
0  0  0
1  0  1
2  0  2
3  1  0
4  1  1
5  1  2
6  2  0
7  2  1
8  2  2

Adding to the crazy ideas: with Python 3 accepting unicode identifiers, you could declare a variable ? = frozenset() (? is U+03D5) and use it instead.

If you have an abstract URL string (not from the current window.location), you can use this trick:

let yourUrlString = "http://example.com:3000/pathname/?search=test#hash";

let parser = document.createElement('a');
parser.href = yourUrlString;

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

The answer comes from the javadoc of ZoneId (emphasis mine) ...

A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:

• Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
• Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply

Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.

... and from the javadoc of ZoneId#of (emphasis mine):

This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.

The argument id is specified as "UTC", therefore it will return a ZoneId with an offset, which also presented in the string form:

System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));

Outputs:

2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]

As you use the equals method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false.

When the normalized() method is used as proposed in the documentation, the comparison using equals will return true, as normalized() will return the corresponding ZoneOffset:

Normalizes the time-zone ID, returning a ZoneOffset where possible.

now.withZoneSameInstant(ZoneOffset.UTC)
    .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true

As the documentation states, if you use "Z" or "+0" as input id, of will return the ZoneOffset directly and there is no need to call normalized():

now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true

To check if they store the same date time, you can use the isEqual method instead:

now.withZoneSameInstant(ZoneOffset.UTC)
    .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true

Sample

System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
        .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));

Output:

equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true

Here's a description of each one followed by with real world sample.

• Dummy - just bogus values to satisfy the API.

  Example: If you're testing a method of a class which requires many mandatory parameters in a constructor which have no effect on your test, then you may create dummy objects for the purpose of creating new instances of a class.

• Fake - create a test implementation of a class which may have a dependency on some external infrastructure. (It's good practice that your unit test does NOT actually interact with external infrastructure.)

  Example: Create fake implementation for accessing a database, replace it with in-memory collection.

• Stub - override methods to return hard-coded values, also referred to as state-based.

  Example: Your test class depends on a method Calculate() taking 5 minutes to complete. Rather than wait for 5 minutes you can replace its real implementation with stub that returns hard-coded values; taking only a small fraction of the time.

• Mock - very similar to Stub but interaction-based rather than state-based. This means you don't expect from Mock to return some value, but to assume that specific order of method calls are made.

  Example: You're testing a user registration class. After calling Save, it should call SendConfirmationEmail.

Stubs and Mocks are actually sub types of Mock, both swap real implementation with test implementation, but for different, specific reasons.

This is what I have come up with so far after studying the rest of the answers. It should be able to support touch-only, mouse-only or hybrid users.

Create a separate hover class for the hover effect. By default, add this hover class to our button.

We do not want to detect the presence of touch support and disable all hover effects from the very beginning. As mentioned by others, hybrid devices are gaining popularity; people may have touch support but want to use a mouse and vice versa. Therefore, only remove the hover class when the user actually touches the button.

The next problem is, what if the user wants to go back to using a mouse after touching the button? To solve that, we need to find an opportune moment to add back the hover class which we have removed.

However, we cannot add it back immediately after removing it, because the hover state is still active. We may not want to destroy and recreate the entire button as well.

So, I thought of using a busy-waiting algorithm (using setInterval) to check the hover state. Once the hover state is deactivated, we can then add back the hover class and stop the busy-waiting, bringing us back to the original state where the user can use either mouse or touch.

I know busy-waiting isn't that great but I'm not sure if there is an appropriate event. I've considered to add it back in the mouseleave event, but it was not very robust. For example, when an alert pops up after the button is touched, the mouse position shifts but the mouseleave event is not triggered.

Edit: Another approach I tried is to call e.preventDefault() within ontouchstart or ontouchend. It appears to stop the hover effect when the button is touched, but it also stops the button click animation and prevents the onclick function from being called when the button is touched, so you have to call those manually in the ontouchstart or ontouchend handler. Not a very clean solution.

Just a few suggestions:

• Screenshots might be an easy way, but you'll have to make sure the code in the image is big enough and clear enough to read. (not the whole screenshot, just the relevant part)
• If you can embed html then there are lots of tools to generate syntax highlighted html.

You can get them like this

$('#save_value').click(function() {
    $('.ads_Checkbox:checked').each(function() {
        alert($(this).val());
    });
});

I had a similar issue, but disabling the button didn't fully did the trick. There were some other actions that took place when the button was clicked and, sometimes, button wasn't disabled soon enough and when the user double-clicked, 2 events where fired.
I took Pangui's timeout idea, and combined both techniques, disabling the button and includeding a timeout, just in case. And I created a simple jQuery plugin:

var SINGLECLICK_CLICKED = 'singleClickClicked';
$.fn.singleClick = function () {
    var fncHandler; 
    var eventData;
    var fncSingleClick = function (ev) {
        var $this = $(this);
        if (($this.data(SINGLECLICK_CLICKED)) || ($this.prop('disabled'))) {
            ev.preventDefault();
            ev.stopPropagation();
        }
        else {
            $this.data(SINGLECLICK_CLICKED, true);
            window.setTimeout(function () {
                $this.removeData(SINGLECLICK_CLICKED);
            }, 1500);
            if ($.isFunction(fncHandler)) {
                fncHandler.apply(this, arguments);
            }
        }
    }

    switch (arguments.length) {
        case 0:
            return this.click();
        case 1:
            fncHandler = arguments[0];
            this.click(fncSingleClick);
            break;
        case 2: 
            eventData = arguments[0];
            fncHandler = arguments[1];
            this.click(eventData, fncSingleClick);
            break;
    }
    return this;
}

And then use it like this:

$("#button1").singleClick(function () {
   $(this).prop('disabled', true);
   //...
   $(this).prop('disabled', false);
})

I found out a solution about excluding SecurityAutoConfiguration class.

Example:

@SpringBootApplication(exclude = {SecurityAutoConfiguration.class })
public class ReportApplication {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(MyApplication.class, args);
    }
}

Lists are for looping, tuples are for structures i.e. "%s %s" %tuple.

Lists are usually homogeneous, tuples are usually heterogeneous.

Lists are for variable length, tuples are for fixed length.

useLayoutEffect could accomplish this with an empty set of observers ([]) if the functionality is actually similar to componentWillMount -- it will run before the first content gets to the DOM -- though there are actually two updates but they are synchronous before drawing to the screen.

for example:

function MyComponent({ ...andItsProps }) {
     useLayoutEffect(()=> {
          console.log('I am about to render!');
     },[]);

     return (<div>some content</div>);
}

The benefit over useState with an initializer/setter or useEffect is though it may compute a render pass, there are no actual re-renders to the DOM that a user will notice, and it is run before the first noticable render, which is not the case for useEffect. The downside is of course a slight delay in your first render since a check/update has to happen before painting to screen. It really does depend on your use-case, though.

I think personally, useMemo is fine in some niche cases where you need to do something heavy -- as long as you keep in mind it is the exception vs the norm.

use flask 0.9 instead use the following commands sudo pip uninstall flask

sudo pip install flask==0.9

Sometimes this error occurs when you use your schema (dbo) in your query in a wrong way.

for example if you write:

select dbo.prd.name
from dbo.product prd

you will get the error.

In this situations change it to:

select prd.name
from dbo.product prd

You have two options to drop and recreate the procedure in SQL Server 2016.

Starting from SQL Server 2016 - use IF EXISTS

DROP FUNCTION [ IF EXISTS ] { [ schema_name. ] function_name } [ ,...n ]   [;]

Starting from SQL Server 2016 SP1 - use OR ALTER

CREATE [ OR ALTER ] FUNCTION [ schema_name. ] function_name   

If you only need to share data between views/scopes/controllers, the easiest way is to store it in $rootScope. However, if you need a shared function, it is better to define a service to do that.

@Peheje will work, but you will have problem with unicode. To fix it I use the code on https://stackoverflow.com/a/30106551/5277071;

    ).join(''))_x000D_
_x000D_
let parseJwt = token =>_x000D_
  JSON.parse(_x000D_

Out of the box JQuery UI offers this solution:

$( function() {
    $( "#dialog-confirm" ).dialog({
      resizable: false,
      height: "auto",
      width: 400,
      modal: true,
      buttons: {
        "Delete all items": function() {
          $( this ).dialog( "close" );
        },
        Cancel: function() {
          $( this ).dialog( "close" );
        }
      }
    });
  } );

HTML

<div id="dialog-confirm" title="Empty the recycle bin?">
  <p><span class="ui-icon ui-icon-alert" style="float:left; margin:12px 12px 20px 0;">
 </span>These items will be permanently deleted and cannot be recovered. Are you sure?</p>
</div>

You can further customize this by providing a name for the JQuery function and passing the text/title you want displayed as a parameter.

The issue has been resolved while installation of the maven settings is provided as External in Eclipse. The navigation settings are Window --> Preferences --> Installations. Select the External as installation Type, provide the Installation home and name and click on Finish. Finally select this as default installations.

It's easy just add the name which you want to use in quotes before adding vector

a_matrix <- cbind(b_matrix,'Name-Change'= c_vector)

For Each row As DataGridViewRow In yourDGV.SelectedRows
    yourDGV.Rows.Remove(row)
Next

This will delete all rows that had been selected.

You can do this more easy way. And 100% works that you want

    $con = new mysqli($servername, $username, $password, $dbname);

    if ($con->connect_error) {
        die("Connection failed: " . $con->connect_error);
    }
    else
    {
        //echo ("Connect Successfully");
    }
    $query = "SELECT Date_time, Tempout FROM alarm_value"; // select column
    $aresult = $con->query($query);

If you want the cells to resize depending on the content, then you must not specify a width to the table, the rows, or the cells.

If you don't want word wrap, assign the CSS style white-space: nowrap to the cells.

If the SSL certificates are not properly installed in your system, you may get this error:

cURL error 60: SSL certificate problem: unable to get local issuer certificate.

You can solve this issue as follows:

Download a file with the updated list of certificates from https://curl.haxx.se/ca/cacert.pem

Move the downloaded cacert.pem file to some safe location in your system

Update your php.ini file and configure the path to that file:

Understand that .children is a property of an Element. ¹ Only Elements have .children, and these children are all of type Element. ²

However, .childNodes is a property of Node. .childNodes can contain any node. ³

A concrete example would be:

let el = document.createElement("div");
el.textContent = "foo";

el.childNodes.length === 1; // Contains a Text node child.
el.children.length === 0;   // No Element children.

Most of the time, you want to use .children because generally you don't want to loop over Text or Comment nodes in your DOM manipulation.

If you do want to manipulate Text nodes, you probably want .textContent instead. ⁴

<sup>1. Technically, it is an attribute of ParentNode, a mixin included by Element.
2. They are all elements because .children is a HTMLCollection, which can only contain elements.
3. Similarly, .childNodes can hold any node because it is a NodeList.
4. Or .innerText. See the differences here or here.</sup>

Use textRect(forBounds:limitedToNumberOfLines:).

class TopAlignedLabel: UILabel {
  override func drawText(in rect: CGRect) {
    let textRect = super.textRect(forBounds: bounds, limitedToNumberOfLines: numberOfLines)
    super.drawText(in: textRect)
  }
}

I was getting the read-only problem even when I was selecting the primary key. I eventually figured out it was a casing problem. Apparently the PK column must be cased the same as defined in the table. using: workbench 6.3 on windows

Read-Only

SELECT leadid,firstname,lastname,datecreated FROM lead;

Allowed edit

SELECT LeadID,firstname,lastname,datecreated FROM lead;

You can add an image resource in the project then (right click on the project and choose the Properties item) access that in this way:

this.picturebox.image = projectname.properties.resources.imagename;

I found an extension method that works quite well

public static string ToHex(this Color color)
{
    return String.Format("#{0}{1}{2}{3}"
        , color.A.ToString("X").Length == 1 ? String.Format("0{0}", color.A.ToString("X")) : color.A.ToString("X")
        , color.R.ToString("X").Length == 1 ? String.Format("0{0}", color.R.ToString("X")) : color.R.ToString("X")
        , color.G.ToString("X").Length == 1 ? String.Format("0{0}", color.G.ToString("X")) : color.G.ToString("X")
        , color.B.ToString("X").Length == 1 ? String.Format("0{0}", color.B.ToString("X")) : color.B.ToString("X"));
}

include the package name with class. It will remove your name. I also got the same issue but adding the package name with class fixed this issue.

data will return you a string representation of a list, but it is actually still a string. Just check the type of data with type(data). That means if you try using indexing on this string representation of a list as such data['fruits'][0], it will return you "[" as it is the first character of data['fruits']

You can do json.loads(data['fruits']) to convert it back to a Python list so that you can interact with regular list indexing. There are 2 other ways you can convert it back to a Python list suggested here
