you can check by putting these code in php file.

<?php
if(in_array  ('curl', get_loaded_extensions())) {
    echo "CURL is available on your web server";
}
else{
    echo "CURL is not available on your web server";
}

OR

var_dump(extension_loaded('curl'));

You can use T-Regx library, that doesn't need delimiters

pattern('^([0-9]+)$')->match($input);

you may need to check whether the settings.xml file is correct. such as user name, password, third party url.

http://constc.blogspot.com/2008/07/undeclared-undefined-null-in-javascript.html

Depends on how specific you want the test to be. You could maybe get away with

if(page_name){ string += "&page_name=" + page_name; }

& is the Bash equivalent for ; ( run commands) and && is the Bash equivalent of && (run commands only when the previous has not caused an error).

Use the format() method for objects of class "yearmon". Here is your example date (properly created!)

date1 <- as.yearmon("Mar 2012", "%b %Y")

Then we can extract the date parts as required:

> format(date1, "%b") ## Month, char, abbreviated
[1] "Mar"
> format(date1, "%Y") ## Year with century
[1] "2012"
> format(date1, "%m") ## numeric month
[1] "03"

These are returned as characters. Where appropriate, wrap in as.numeric() if you want the year or numeric month as a numeric variable, e.g.

> as.numeric(format(date1, "%m"))
[1] 3
> as.numeric(format(date1, "%Y"))
[1] 2012

See ?yearmon and ?strftime for details - the latter explains the placeholder characters you can use.

As a slight improvement over the other answers, you can do the mkdir and chmod as a single operation using mkdir's -m switch.

$ mkdir -m 700 ${HOME}/.ssh

Usage

From a Linux system

$ mkdir --help
Usage: mkdir [OPTION]... DIRECTORY...
Create the DIRECTORY(ies), if they do not already exist.

Mandatory arguments to long options are mandatory for short options too.
  -m, --mode=MODE   set file mode (as in chmod), not a=rwx - umask
...
...

Intro: There are the (probably) best solutions. But you have to know it and remember it and sometimes you have to hope that your Python version isn't too old or whatever the issue could be.

Then there are the most 'hacky' solutions. They are great and short but sometimes are hard to understand, to read and to remember.

There is, though, an alternative which is to to try to reinvent the wheel. - Why reinventing the wheel? - Generally because it's a really good way to learn (and sometimes just because the already-existing tool doesn't do exactly what you would like and/or the way you would like it) and the easiest way if you don't know or don't remember the perfect tool for your problem.

So, I propose to reinvent the wheel of the Counter class from the collections module (partially at least):

class MyDict(dict):
    def __add__(self, oth):
        r = self.copy()

        try:
            for key, val in oth.items():
                if key in r:
                    r[key] += val  # You can custom it here
                else:
                    r[key] = val
        except AttributeError:  # In case oth isn't a dict
            return NotImplemented  # The convention when a case isn't handled

        return r

a = MyDict({'a':1, 'b':2, 'c':3})
b = MyDict({'b':3, 'c':4, 'd':5})

print(a+b)  # Output {'a':1, 'b': 5, 'c': 7, 'd': 5}

There would probably others way to implement that and there are already tools to do that but it's always nice to visualize how things would basically works.

One way using awk:

tail -f file.txt | awk '/A1/ { print $NF }'

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Threading;

namespace ConsoleApp6
{
    class Program
    {
        static void Main(string[] args)
        {

            int x = 10;
            Thread t1 =new Thread(new ParameterizedThreadStart(order1));
            t1.IsBackground = true;//i can stope 
            t1.Start(x);

            Thread t2=new Thread(order2);
            t2.Priority = ThreadPriority.Highest;
            t2.Start();

            Console.ReadKey();
        }//Main

        static void  order1(object args)
        {
            int x = (int)args;


                for (int i = 0; i < x; i++)
            {
                Console.ForegroundColor = ConsoleColor.Green;
                Console.Write(i.ToString() + " ");
            }
        }

        static void order2()
        {
            for (int i = 100; i > 0; i--)
            {
                Console.ForegroundColor = ConsoleColor.Red;
                Console.Write(i.ToString() + " ");
            }
        }`enter code here`
    }
}

I would use the element.addEventListener method to link it to a function. From that function you can call multiple functions.

The advantage I see in binding an event to a single function and then calling multiple functions is that you can perform some error checking, have some if else statements so that some functions only get called if certain criteria are met.

How about this one...

int value = 0xFACE;

value = ((0xFF & value << 8) | (val >> 8);

This worked for me:
If you are comparing two lists of objects depend upon single entity like ID, and you want a third list which matches that condition, then you can do the following:

var list3 = List1.Where(n => !List2.select(n1 => n1.Id).Contains(n.Id));

Refer: MSDN - C# Compare Two lists of objects

Use docker-compose and multiple Dockerfile in separate directories

Don't rename your Dockerfile to Dockerfile.db or Dockerfile.web, it may not be supported by your IDE and you will lose syntax highlighting.

As Kingsley Uchnor said, you can have multiple Dockerfile, one per directory, which represent something you want to build.

I like to have a docker folder which holds each applications and their configuration. Here's an example project folder hierarchy for a web application that has a database.

docker-compose.yml
docker
+-- web
¦   +-- Dockerfile
+-- db
    +-- Dockerfile

docker-compose.yml example:

version: '3'
services:
  web:
    # will build ./docker/web/Dockerfile
    build: ./docker/web
    ports:
     - "5000:5000"
    volumes:
     - .:/code
  db:
    # will build ./docker/db/Dockerfile
    build: ./docker/db
    ports:
      - "3306:3306"
  redis:
    # will use docker hub's redis prebuilt image from here:
    # https://hub.docker.com/_/redis/
    image: "redis:alpine"

docker-compose command line usage example:

# The following command will create and start all containers in the background
# using docker-compose.yml from current directory
docker-compose up -d

# get help
docker-compose --help

In case you need files from previous folders when building your Dockerfile

You can still use the above solution and place your Dockerfile in a directory such as docker/web/Dockerfile, all you need is to set the build context in your docker-compose.yml like this:

version: '3'
services:
  web:
    build:
      context: .
      dockerfile: ./docker/web/Dockerfile
    ports:
     - "5000:5000"
    volumes:
     - .:/code

This way, you'll be able to have things like this:

config-on-root.ini
docker-compose.yml
docker
+-- web
    +-- Dockerfile
    +-- some-other-config.ini

and a ./docker/web/Dockerfile like this:

FROM alpine:latest

COPY config-on-root.ini /
COPY docker/web/some-other-config.ini /

Here are some quick commands from tldr docker-compose. Make sure you refer to official documentation for more details.

public enum FetchType extends java.lang.Enum Defines strategies for fetching data from the database. The EAGER strategy is a requirement on the persistence provider runtime that data must be eagerly fetched. The LAZY strategy is a hint to the persistence provider runtime that data should be fetched lazily when it is first accessed. The implementation is permitted to eagerly fetch data for which the LAZY strategy hint has been specified. Example: @Basic(fetch=LAZY) protected String getName() { return name; }

    // Disable #x
    $( "#x" ).prop( "disabled", true );
    // Enable #x
    $( "#x" ).prop( "disabled", false );

Sometimes you need to disable/enable the form element like input or textarea. Jquery helps you to easily make this with setting disabled attribute to "disabled". For e.g.:

  //To disable 
  $('.someElement').attr('disabled', 'disabled');

To enable disabled element you need to remove "disabled" attribute from this element or empty it's string. For e.g:

//To enable 
$('.someElement').removeAttr('disabled');

// OR you can set attr to "" 
$('.someElement').attr('disabled', '');

refer :http://garmoncheg.blogspot.fr/2011/07/how-to-disableenable-element-with.html

There are libraries that do charset conversion in Javascript. But if you want something simple, this function does approximately what you want:

function stringToBytes(text) {
  const length = text.length;
  const result = new Uint8Array(length);
  for (let i = 0; i < length; i++) {
    const code = text.charCodeAt(i);
    const byte = code > 255 ? 32 : code;
    result[i] = byte;
  }
  return result;
}

If you want to convert the resulting byte array into a Blob, you would do something like this:

const originalString = 'ååå';
const bytes = stringToBytes(originalString);
const blob = new Blob([bytes.buffer], { type: 'text/plain; charset=ISO-8859-1' });

Now, keep in mind that some apps do accept UTF-8 encoding, but they can't guess the encoding unless you prepend a BOM character, as explained here.

While taking the advice above with schtasks, you can see in the UI what must be done to perform an hourly task. When you edit trigger begin the task on a schedule, One Time (this is the key). Then you can select "Repeat task every:" 1 hour or whatever you wish. See screenshot:

If you know the some content of the file you can try to decode it with several encoding and see which is missing. In general there is no way since a text file is a text file and those are stupid ;)

use display:inline-block; instead of float

you can't centre floats, but inline-blocks centre as if they were text, so on the outer overall container of your "row" - you would set text-align: center; then for each image/caption container (it's those which would be inline-block;) you can re-align the text to left if you require

You only need one INSERT:

INSERT INTO table4 ( name, age, sex, city, id, number, nationality)
SELECT name, age, sex, city, p.id, number, n.nationality
FROM table1 p
INNER JOIN table2 c ON c.Id = p.Id
INNER JOIN table3 n ON p.Id = n.Id

I usualy use <li> to include <a> link. I disabled click action writing like this; You may not include <a> link, then you will ignore my post.

a.noclick       {_x000D_
  pointer-events: none;_x000D_
}

<a class="noclick" href="#">this is disabled</a>

Without using CTE and ROW_NUMBER() you can just delete the records just by using group by with MAX function here is and example

DELETE
FROM MyDuplicateTable
WHERE ID NOT IN
(
SELECT MAX(ID)
FROM MyDuplicateTable
GROUP BY DuplicateColumn1, DuplicateColumn2, DuplicateColumn3)

for those who want some official document to confirm the behavior

Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment. (If the ‘-e’ flag is specified, then values from the environment override assignments in the makefile.

When setup a job in new windows you have two fields "program/script" and "Start in(Optional)". Put program name in first and program location in second. If you will not do that and your program start not in directory with exe, it will not find files that are located in it.

There is a property in the drawable xml to do it. android:tileMode="repeat"

See this site: http://androidforbeginners.blogspot.com/2010/06/how-to-tile-background-image-in-android.html

SSL properties are set at the JVM level via system properties. Meaning you can either set them when you run the program (java -D....) Or you can set them in code by doing System.setProperty.

The specific keys you have to set are below:

javax.net.ssl.keyStore- Location of the Java keystore file containing an application process's own certificate and private key. On Windows, the specified pathname must use forward slashes, /, in place of backslashes.

javax.net.ssl.keyStorePassword - Password to access the private key from the keystore file specified by javax.net.ssl.keyStore. This password is used twice: To unlock the keystore file (store password), and To decrypt the private key stored in the keystore (key password).

javax.net.ssl.trustStore - Location of the Java keystore file containing the collection of CA certificates trusted by this application process (trust store). On Windows, the specified pathname must use forward slashes, /, in place of backslashes, \.

If a trust store location is not specified using this property, the SunJSSE implementation searches for and uses a keystore file in the following locations (in order):

1. $JAVA_HOME/lib/security/jssecacerts
2. $JAVA_HOME/lib/security/cacerts

javax.net.ssl.trustStorePassword - Password to unlock the keystore file (store password) specified by javax.net.ssl.trustStore.

javax.net.ssl.trustStoreType - (Optional) For Java keystore file format, this property has the value jks (or JKS). You do not normally specify this property, because its default value is already jks.

javax.net.debug - To switch on logging for the SSL/TLS layer, set this property to ssl.

You can remove upstream using

git branch --unset-upstream

The above command will also remove the tracking stream branch, hence if you want to rebase from repository you have use

git rebase origin master

I am using Angular 5.2 and when I use import 'rxjs/Rx'; it throws me the following lint error: TSLint: This import is blacklisted, import a submodule instead (import-blacklist)

See the screenshot below:

SOLUTION: Solved it by importing only the operators that I needed. Example follows:

import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';

So the fix would be to import specifically only the necessary operators.

Sometimes even after installing python-dev the error persists, Check for the error if it is 'gcc' missing.

First download as stated in https://stackoverflow.com/a/21530768/8687063, then install gcc

For apt (Ubuntu, Debian...):

sudo apt-get install gcc

For yum (CentOS, RHEL...):

sudo yum install gcc

For dnf (Fedora...):

sudo dnf install gcc

For zypper (openSUSE...):

sudo zypper in gcc

For apk (Alpine...):

sudo apk gcc

One line in the Makefile should be enough:

DIR := $(notdir $(CURDIR))

Here is a solution that doesn't use the dangerouslySetInnerHTML which is dangerous as the name says.

import { IntlProvider, FormattedMessage } from "react-intl";

<FormattedMessage
          id="app.greeting"
          description="Bold text example"
          defaultMessage="Look here, I can include HTML tags in plain string and render them as HTML: <b>Bold</b>, <i>Italics</i> and <a>links too</a>."
          values={{
            b: (chunks) => <b>{chunks}</b>,
            i: (chunks) => <i>{chunks}</i>,
            a: (chunks) => (
              <a class="external_link" target="_blank" href="https://jiga.dev/">
                {chunks}
              </a>
            )
          }}
        />

This should be rendered as:

Full example in https://jiga.dev/react-render-string-with-html-tags-from-props/

1. Create two hidden iframes (add "display: none;" to the css style). Make your second iframe point to something on your own domain.

2. Create a hidden form, set its method to "post" with target = your first iframe, and optionally set enctype to "multipart/form-data" (I'm thinking you want to do POST because you want to send multipart data like pictures?)

3. When ready, make the form submit() the POST.

4. If you can get the other domain to return javascript that will do Cross-Domain Communication With Iframes (http://softwareas.com/cross-domain-communication-with-iframes) then you are in luck, and you can capture the response as well.

Of course, if you want to use your server as a proxy, you can avoid all this. Simply submit the form to your own server, which will proxy the request to the other server (assuming the other server isn't set up to notice IP discrepancies), get the response, and return whatever you like.

Since Spark 2.X spark-csv is integrated as native datasource. Therefore, the necessary statement simplifies to (windows)

df.write
  .option("header", "true")
  .csv("file:///C:/out.csv")

or UNIX

df.write
  .option("header", "true")
  .csv("/var/out.csv")

Notice: as the comments say, it is creating the directory by that name with the partitions in it, not a standard CSV file. This, however, is most likely what you want since otherwise your either crashing your driver (out of RAM) or you could be working with a non distributed environment.

VB version of C# given by Brannon:

Public Sub DisplayAll(ByVal Someobject As Foo)
    Dim _type As Type = Someobject.GetType()
    Dim properties() As PropertyInfo = _type.GetProperties()  'line 3
    For Each _property As PropertyInfo In properties
        Console.WriteLine("Name: " + _property.Name + ", Value: " + _property.GetValue(Someobject, Nothing))
    Next
End Sub

Using Binding flags in instead of line no.3

    Dim flags As BindingFlags = BindingFlags.Public Or BindingFlags.Instance
    Dim properties() As PropertyInfo = _type.GetProperties(flags)

You can't use a primitive because HashMap use object internally for the key. So you can only use an object that inherits from Object (that is any object).

That is the function put() in HashMap and as you can see it uses Object for K:

public V put(K key, V value) {
    if (key == null)
        return putForNullKey(value);
    int hash = hash(key);
    int i = indexFor(hash, table.length);
    for (Entry<K,V> e = table[i]; e != null; e = e.next) {
        Object k;
        if (e.hash == hash && ((k = e.key) == key || key.equals(k))) {
            V oldValue = e.value;
            e.value = value;
            e.recordAccess(this);
            return oldValue;
        }
    }

    modCount++;
    addEntry(hash, key, value, i);
    return null;
}

The expression "k = e.key" should make it clear.

I suggest to use a wrapper like Integer and autoboxing.

This should do it:

<style>
body {
    background:url(bg.jpg) fixed no-repeat bottom right;
}
</style>

http://www.w3schools.com/cssref/pr_background-position.asp

Another possibility can be connection reset from the TCP wrappers (/etc/hosts.deny and /etc/hosts.allow). Just check what is coming in from the telnet to port 3306 - if it is nothing, then there is something is in the middle preventing communication from happening.

IB and Swift

Given the flowing layout where yellow is the superview and red, green, and blue are sibling subviews of yellow,

the goal is to move a subview (let's say green) to the top.

In Interface Builder

In the Interface Builder all you need to do is drag the view you want showing on the top to the bottom of the list in the Documents Outline.

Alternatively, you can select the view and then in the menu go to Editor > Arrange > Send to Front.

In Swift

There are a couple of different ways to do this programmatically.

Method 1

yellowView.bringSubviewToFront(greenView)

• This method is the programmatic equivalent of the IB answer above.

• It only works if the subviews are siblings of each other.

• An array of the subviews is contained in yellowView.subviews. Here, bringSubviewToFront moves the greenView from index 0 to 2. This can be observed with

    print(yellowView.subviews.indexOf(greenView))
  

Method 2

greenView.layer.zPosition = 1

• This method just moves the 3D position of the layer higher (closer to the user) on the z-axis. Since the default is 0 for all the other views, the result is that the greenView looks like it is on top. However, it still remains at index 0 of the yellowView.subviews array. This can cause some unexpected results, though, because things like tap events will still go first to the view with the highest index number. For that reason, it might be better to go with Method 1 above.
• The zPosition could be set to CGFloat.greatestFiniteMagnitude (CGFloat(FLT_MAX) in older versions of Swift) to ensure that it is on top.

Leaving my specific solution of this for prosperity, as it's a tricky version of this problem:

Type 'System.Linq.Enumerable+WhereSelectArrayIterator[T...] was not marked as serializable

Due to a class with an attribute IEnumerable<int> eg:

[Serializable]
class MySessionData{
    public int ID;
    public IEnumerable<int> RelatedIDs; //This can be an issue
}

Originally the problem instance of MySessionData was set from a non-serializable list:

MySessionData instance = new MySessionData(){ 
    ID = 123,
    RelatedIDs = nonSerizableList.Select<int>(item => item.ID)
};

The cause here is the concrete class that the Select<int>(...) returns, has type data that's not serializable, and you need to copy the id's to a fresh List<int> to resolve it.

RelatedIDs = nonSerizableList.Select<int>(item => item.ID).ToList();

var img = document.createElement('img');
img.src = 'my_image.jpg';
document.getElementById('container').appendChild(img);

Just a little more clarification: A property without 'get','set' won't be able to be bound

I'm facing the case just like the asker's case. And I must have the following things in order for the bind to work properly:

//(1) Declare a property with 'get','set' in code behind
public partial class my_class:Window {
  public String My_Property { get; set; }
  ...

//(2) Initialise the property in constructor of code behind
public partial class my_class:Window {
  ...
  public my_class() {
     My_Property = "my-string-value";
     InitializeComponent();
  }

//(3) Set data context in window xaml and specify a binding
<Window ...
DataContext="{Binding RelativeSource={RelativeSource Self}}">
  <TextBlock Text="{Binding My_Property}"/>
</Window>

Here's a jquery plugin to do the same: http://s.technabled.com/jquery-foggle

If you want to know the port number of your local host on which Mysql is running you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'port';


mysql> SHOW VARIABLES WHERE Variable_name = 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set (0.00 sec)

It will give you the port number on which MySQL is running.

If you want to know the hostname of your Mysql you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'hostname';


mysql> SHOW VARIABLES WHERE Variable_name = 'hostname';
+-------------------+-------+
| Variable_name     | Value |
+-------------------+-------+
| hostname          | Dell  |
+-------------------+-------+
1 row in set (0.00 sec)

It will give you the hostname for mysql.

If you want to know the username of your Mysql you can use this query on MySQL Command line client --

select user();   


mysql> select user();
+----------------+
| user()         |
+----------------+
| root@localhost |
+----------------+
1 row in set (0.00 sec)

It will give you the username for mysql.

You can print duplicate and Unqiue using below logic using list.

def dup(x):
    duplicate = []
    unique = []
    for i in x:
        if i in unique:
            duplicate.append(i)
        else:
            unique.append(i)
    print("Duplicate values: ",duplicate)
    print("Unique Values: ",unique)

list1 = [1, 2, 1, 3, 2, 5]
dup(list1)

To follow debobroto das's answer you can also put after

input.reset();
input.next(); 

I had the same problem and when I tried this. It completely fixed it.

In /etc/hosts:

1. Add this line:

your-ip-address your-host-name

example: 192.168.1.8 master

In /etc/hosts:

2. Delete the line with 127.0.1.1 (This will cause loopback)

3. In your core-site, change localhost to your-ip or your-hostname

Now, restart the cluster.

List<String> list = new ArrayList<String>();
Map<String, String> map = new HashMap<String, String>();
for (String str : map.keySet()) {
 list.add(str);
}
Collections.sort(list);
for (String str : list) {
 System.out.println(str);
}

I had a similar problem. As you increase the line-height the space above the text increases. It's not padding but it will affect the vertical space between content. I found that adding a -ve top margin seemed to do the trick. It had to be done for all of the different instances of line-height and it varies with font-family too. Maybe this is something which designers need to be more aware of when passing design requirements (?) So for a particular instance of font-family and line-height:

h1 {
    font-family: 'Garamond Premier Pro Regular';
    font-size: 24px;
    color: #001230;
    line-height: 29px;
    margin-top: -5px;    /* CORRECTION FOR LINE-HEIGHT */
}

Add all the strings to a dictionary and get the Keys property afterwards. This will produce each unique string, but not necessarily in the same order your original input had them in.

If you require the end result to have the same order as the original input, when you consider the first occurance of each string, use the following algorithm instead:

1. Have a list (final output) and a dictionary (to check for duplicates)
2. For each string in the input, check if it exists in the dictionary already
3. If not, add it both to the dictionary and to the list

At the end, the list contains the first occurance of each unique string.

Make sure you consider things like culture and such when constructing your dictionary, to make sure you handle duplicates with accented letters correctly.

Well, here the positioning of the css and script links makes a to of difference. Bootstrap executes in CSS and then Scripts fashion. So if you have even one script written at incorrect place it makes a lot of difference. You can follow the below snippet and change your code accordingly.

If you enable Query Store on SQL Server 2016 or newer you can use the following query to get last SP execution. The history depends on the Query Store Configuration.

SELECT 
      ObjectName = '[' + s.name + '].[' + o.Name  + ']'
    , LastModificationDate  = MAX(o.modify_date)
    , LastExecutionTime     = MAX(q.last_execution_time)
FROM sys.query_store_query q 
    INNER JOIN sys.objects o
        ON q.object_id = o.object_id
    INNER JOIN sys.schemas s
        ON o.schema_id = s.schema_id
WHERE o.type IN ('P')
GROUP BY o.name , + s.name 

In simple words other major difference is that IEnumerable execute select query on server side, load data in-memory on client side and then filter data while IQueryable execute select query on server side with all filters.

Suppose you have a tree like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]

First, checkout a temp branch:

git checkout -b temp

On temp branch, reset --hard to a commit that you want to change its message (for example, that commit is 946992):

git reset --hard 946992

Use amend to change the message:

git commit --amend -m "<new_message>"

After that the tree will look like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
           \
            b886a0 [temp]

Then, cherry-pick all the commit that is ahead of 946992 from master to temp and commit them, use amend if you want to change their messages as well:

git cherry-pick 9143a9
git commit --amend -m "<new_message>
...
git cherry-pick 5a6057
git commit --amend -m "<new_message>

The tree now looks like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
               \
                b886a0 - 41ab2c - 6c2a3s - 7c88c9 [temp]

Now force push the temp branch to remote:

git push --force origin temp:master

The final step, delete branch master on local, git fetch origin to pull branch master from the server, then switch to branch master and delete branch temp.

Now both your local and remote will have all the messages updated.

If re-starting Eclipse does not correct the problem, make sure that the image name begins with an alpha character (non-numeric).

For doing FORM posts, the best way is to use WebClient.UploadValues() with a POST method.

No, it's not possible.

It's really, if not use native selects, if you create custom select widget from html elements, t.e. "li".

If two different views are sharing the same model (for instance, maybe one is for mobile output and one is regular), it could be nice to have the string reside in a single place: as metadata on the ViewModel.

Additionally, if you had an inherited version of the model that necessitated a different display, it could be useful. For instance:

public class BaseViewModel
{
    [Display(Name = "Basic Name")]
    public virtual string Name { get; set; }
}

public class OtherViewModel : BaseViewModel
{
    [Display(Name = "Customized Inherited Name")]
    public override string Name { get; set; }
}

I'll admit that that example is pretty contrived...

Those are the best arguments in favor of using the attribute that I can come up with. My personal opinion is that, for the most part, that sort of thing is best left to the markup.

I had the same problem, with a RESTful API running on aspnet core.

I didn't want to uninstall the WebDAV, and I tried most of the remedies described above. I tried to set the verbs="*" both on the site and on the server itself, but without success.

What did the trick for me was the following:

IIS Manager -> Sites -> MySite -> HandlerMappings -> aspNetCore -> Edit

-> Request Restrictions -> Access -> None (it was Script).

After that everything worked, even if I replaced the original WebDAV options.

you can do it Pragmatically also

  GradientDrawable gradientDrawable=new GradientDrawable();
   gradientDrawable.setStroke(4,getResources().getColor(R.color.line_Input));

Then set the background of layout as :

LinearLayout layout = (LinearLayout ) findViewById(R.id.ayout); layout .setBackground(gradientDrawable);

Edit based on better answer below. Go down about 3 answers and find out about the coolness of basestring.

Old answer: Watch out for unicode strings, which you can get from several places, including all COM calls in Windows.

if isinstance(target, str) or isinstance(target, unicode):

Solution with Jquery

$(window).resize(function () {
    var width = $("#map").width();
    $("#map").height(width * 1.72);
});

I have the same problem and I followed this Post, it solved my problem.

Follow the following 2 steps:

1. Make sure the optimization level is -O0
2. Add -ggdb flag when compiling your program

Good luck!

Have you tried?

var isoDateTimeFormat = CultureInfo.InvariantCulture.DateTimeFormat;

// "2013-10-10T22:10:00"
 dateValue.ToString(isoDateTimeFormat.SortableDateTimePattern); 

// "2013-10-10 22:10:00Z"    
dateValue.ToString(isoDateTimeFormat.UniversalSortableDateTimePattern)

Also try using parameters when you store the c# datetime value in the mySql database, this might help.

CREATE TABLE someTable (
    id serial PRIMARY KEY,
    col1 int NOT NULL,
    col2 int NOT NULL,
    UNIQUE (col1, col2)
)

autoincrement is not postgresql. You want a serial.

If col1 and col2 make a unique and can't be null then they make a good primary key:

CREATE TABLE someTable (
    col1 int NOT NULL,
    col2 int NOT NULL,
    PRIMARY KEY (col1, col2)
)

- (void)GetCurrentTimeStamp
    {
        NSDateFormatter *objDateformat = [[NSDateFormatter alloc] init];
        [objDateformat setDateFormat:@"yyyy-MM-dd"];

        NSDate *objUTCDate  = [objDateformat dateFromString:strUTCTime];
        long long milliseconds = (long long)([objUTCDate timeIntervalSince1970] * 1000.0);

        NSString *strTimeStamp = [Nsstring stringwithformat:@"%lld",milliseconds];
        NSLog(@"The Timestamp is = %@",strTimestamp);
    }

        [dateFormatter setDateFormat:@"yyyy-MM-dd"];
        NSDate  *objDate    = [dateFormatter dateFromString:IN_strLocalTime];
        [dateFormatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];
        NSString *strDateTime   = [dateFormatter stringFromDate:objDate];
        return strDateTime;
    }

NOTE :- The Timestamp must be in UTC Zone, So I convert our local Time to UTC Time.

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

Using your example, you could do:

public void doit(A a) {
    if(a instanceof B) {
        // needs to cast to B to access draw2 which isn't present in A
        // note that this is probably not a good OO-design, but that would
        // be out-of-scope for this discussion :)
        ((B)a).draw2();
    }
    a.draw();
}

The best answer to this could be

Don't use selct for this job use input instead

like this

echo  $this->Form->input('field_name', array(
          'type' => 'select',
            'options' => $options_arr, 
            'label' => 'label here',
            'value' => $id,  // default value
            'escape' => false,  // prevent HTML being automatically escaped
            'error' => false,
            'class' => 'form-control' // custom class you want to enter
        ));

Hope it helps.

It's because you cannot access protected member data through its class instance. You should correct your code as follows:

namespace homeworkchap8
{
    class main
    {    
        static void Main(string[] args)
        {    
            SteelClubs myClub = new SteelClubs();
            Console.WriteLine("How far to the hole?");
            myClub.mydistance = Console.ReadLine();
            Console.WriteLine("what club are you going to hit?");
            myClub.myclub = Console.ReadLine();
            myClub.SwingClub();

            SteelClubs mycleanclub = new SteelClubs();
            Console.WriteLine("\nDid you clean your club after?");
            mycleanclub.mycleanclub = Console.ReadLine();
            mycleanclub.clean();

            SteelClubs myScoreonHole = new SteelClubs();
            Console.WriteLine("\nWhat hole are you on?");
            myScoreonHole.myhole = Console.ReadLine();
            Console.WriteLine("What did you score on the hole?");
            myScoreonHole.myscore = Console.ReadLine();
            Console.WriteLine("What is the par of the hole?");
            myScoreonHole.parhole = Console.ReadLine();

            myScoreonHole.score();

            Console.ReadKey();    
        }
    }
}

1. Install App::cpanminus from CPAN (use: cpan App::cpanminus for this).
2. Type cpanm --uninstall Module::Name (note the "m") to uninstall the module with cpanminus.

This should work.

I had trouble with all the answers here because I was working with a HUGE file (~300Gb) and none of the solutions scaled. Here's my solution:

dd if=/dev/null of=<filename> bs=1 seek=$(echo $(stat --format=%s <filename> ) - $( tail -n1 <filename> | wc -c) | bc )

In words: Find out the length of the file you want to end up with (length of file minus length of length of its last line, using bc) and, set that position to be the end of the file (by dding one byte of /dev/null onto it).

This is fast because tail starts reading from the end, and dd will overwrite the file in place rather than copy (and parse) every line of the file, which is what the other solutions do.

NOTE: This removes the line from the file in place! Make a backup or test on a dummy file before trying it out on your own file!

$link = mysqli_connect('127.0.0.1', 'my_user', 'my_pass', 'my_db');
mysqli_query($link, "INSERT INTO mytable (1, 2, 3, 'blah')");
$id = mysqli_insert_id($link);

See mysqli_insert_id().

Whatever you do, don't insert and then do a "SELECT MAX(id) FROM mytable". Like you say, it's a race condition and there's no need. mysqli_insert_id() already has this functionality.

This worked for me: .\mongod --dbpath c:......

In Other ways to get difference between date;

import dateutil.parser
import datetime
last_sent_date = "" # date string
timeDifference = current_date - dateutil.parser.parse(last_sent_date)
time_difference_in_minutes = (int(timeDifference.days) * 24 * 60) + int((timeDifference.seconds) / 60)

So get output in Min.

Thanks

My two cents

1. Indexes can fail when not using the correct datatypes:
   In SQL Server: When you have an index over a VARCHAR column and present it a Unicode String, SQL Server does not make use of the index. The same thing happens when you present a BigInt to a indexed-column containing SmallInt. Even if the BigInt is small enough to be a SmallInt, SQL Server is not able to use the index. The other way around you do not have this problem (when providing SmallInt or Ansi-Code to an indexed BigInt ot NVARCHAR column).

2. Datatypes can vary between different DBMS's (DataBase Management System):
   Know that every database has slightly different datatypes and VARCHAR does not means the same everywhere. While SQL Server has VARCHAR and NVARCHAR, an Apache/Derby database has only VARCHAR and there VARCHAR is in Unicode.

Try this

import ("strconv")

value := "123"
number,err := strconv.ParseUint(value, 10, 32)
finalIntNum := int(number) //Convert uint64 To int

I had the same issue. My tomcat was started but I was getting HTTP 404 page not found.However, in my situation, I installed tree instances of tomcat. Each instance contains conf, temp, work, webapps and logs folders. Unless I forgot, to copy the global web.xml under conf folder of each tomcat.

    e.g: /opt/tomcat/mytomcatInstance/conf/web.xml 

The web.xml Deployment Descriptor file describes how to deploy a web application in a servlet container.

So even if my tomcat was up, my web apps could not be deployed properly.

In case this helps someone, for me, none of the above was sufficient. I still couldn't build, VS still couldn't find the references. The key was simply to close and reopen the solution after restoring the packages.

Here's the scenario (using Visual Studio 2012):

You open a Solution that has missing packages. The references show that VS can't find them. There are many ways to restore the missing packages, including

• building a solution that is set to auto-restore
• opening the Package Manager Console and clicking the nice "Restore" button
• doing nuget restore if you have the command line nuget installed

But no matter what the approach, those references will still be shown as missing. And when you build it will fail. Sigh. However if you close the solution and re-open it, now VS checks those nice <HintPath>s again, finds that the packages are back where they belong, and all is well with the world.

Update

Is Visual Studio still not seeing that you have the package? Still showing a reference that it can't resolve? Make sure that the version of package you restored is exactly the same as the <HintPath> in your .csproj file. Even a minor bug fix number (e.g. 1.10.1 to 1.10.2) will cause the reference to fail. You can fix this either by directly editing your csproj xml, or else by removing the reference and making a new one pointing at the newly-restored version in the packages directory.

Try, the following code..

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

From what I know, respond_to is a method attached to the ActionController, so you can use it in every single controller, because all of them inherits from the ActionController. Here is the Rails respond_to method:

def respond_to(&block)
  responder = Responder.new(self)
  block.call(responder)
  responder.respond
end

You are passing it a block, like I show here:

respond_to <<**BEGINNING OF THE BLOCK**>> do |format|
  format.html
  format.xml  { render :xml => @whatever }
end <<**END OF THE BLOCK**>>

The |format| part is the argument that the block is expecting, so inside the respond_to method we can use that. How?

Well, if you notice we pass the block with a prefixed & in the respond_to method, and we do that to treat that block as a Proc. Since the argument has the ".xml", ".html" we can use that as methods to be called.

What we basically do in the respond_to class is call methods ".html, .xml, .json" to an instance of a Responder class.

Indeed there is an API to search google programmatically. The API is called google custom search. For using this API, you will need an Google Developer API key and a cx key. A simple procedure for accessing google search from java program is explained in my blog.

In Android O and later this error happens when you set

 android:screenOrientation="portrait"

in Manifest.

Remove that line and use

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

in your activity.

This will fix your issue.

You can do it like this:

<form class="form-horizontal" role="form">
    <div class="form-group">
        <label for="inputType" class="col-sm-2 control-label">Label</label>
        <div class="col-sm-4">
            <input type="text" class="form-control" id="input" placeholder="Input text">
        </div>
    </div>
</form>

<a href="javascript:call_func();">...</a>

where the function then has to return false so that the browser doesn't go to another page.

But I'd recommend to use jQuery (with $(...).click(function () {})))

Why not just create a 1dp high view with a background color? Then it can be easily placed where you want.

With quotes around the date:

or replace 50px with whatever you want.

What you can do is:

1. Update your local git repo:

   git fetch

2. Build a local branch and checkout on it:

   git branch pouet && git checkout pouet

3. Apply the commit you want on this branch:

   git cherry-pick abcdefabcdef

   (abcdefabcdef is the sha1 of the commit you want to apply)

Seven years after the inception of the App Store (July 10, 2008), Apple has finally introduced a new feature in Xcode 7 that allows you to deploy and run any number of apps on any of your devices, simply by logging in with your Apple ID. You will no longer need a paid Program membership to deploy apps on your own device (and you certainly no longer have to jailbreak your device if you're not comfortable doing so).

Well, not for the majority of use cases anyway. For obvious reasons, certain capabilities and entitlements that require Program membership such as Game Center and in-app purchases will not be available to apps deployed using this method. From Apple's developer documentation:

Launch Your App on Devices Using Free Provisioning (iOS, watchOS)

If you don’t join the Apple Developer Program, you can still build and run your app on your devices using free provisioning. However, the capabilities available to your app, described in Adding Capabilities, are restricted when you don’t belong to the Apple Developer Program.

The precise steps to getting your app onto your iOS device or Apple Watch follow immediately thus (screenshots omitted for ease of skimming):

1. In Xcode, add your Apple ID to Accounts preferences, described in Adding Your Apple ID Account in Xcode.

2. In the project navigator, select the project and your target to display the project editor.

3. Click General and choose your name from the Team pop-up menu.

4. Connect the device to your Mac and choose your device from the Scheme toolbar menu.

5. Below the Team pop-up menu, click Fix Issue.

   Xcode creates a free provisioning profile for you and the warning text under the Team pop-up menu disappears.

6. Click the Run button.

   Xcode installs the app on the device before launching the app.

Prior to Xcode 7, a Program membership was indeed required in order to sign the provisioning certificates required to deploy apps to devices. The only other alternative was jailbreaking. With Xcode 7, you no longer need to jailbreak your device just to run apps distributed outside the App Store, or to test apps if you cannot afford to join the Program, or to deploy and use apps that you have developed for your own personal use if you do not intend to distribute them through the App Store (in which case you probably don't need the entitlements offered by Program membership anyway).

I solved that issue follow that:

Steps:

1. Make sure that Aggressive Wi-Fi to Cellular handover under Networking section in the device's developer options is turned off.
2. Ping continuously from your pc to the device to make sure it's not in network idle mode ping -t 194.68.0.100 (windows cmd), unlock the device and even try to surf to some website just to make it get out of the network idle.
3. If ping doesn't work, turn off / on Android Wifi and go back to step 2.

4. When it replies to the ping, connect it via USB, and:

   adb usb

   adb tcpip 5555

   adb connect 194.68.0.100:5555

In casr it's still not connected, try to switch the usb connection mode as MTP / PTP / Camera while the device is connected through usb and repeat these steps over again...

std::remove does not actually erase the element from the container, but it does return the new end iterator which can be passed to container_type::erase to do the REAL removal of the extra elements that are now at the end of the container:

std::vector<int> vec;
// .. put in some values ..
int int_to_remove = n;
vec.erase(std::remove(vec.begin(), vec.end(), int_to_remove), vec.end());

Sometimes a binder throwns an exception with no error message. You can retrieve the exception with the following snippet to find out whats wrong:

(Often if the binder is trying to convert strings to complex types etc)

 if (!ModelState.IsValid)
            {
var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));

// Breakpoint, Log or examine the list with Exceptions.

  }

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

I had the same requirement, but when using the accepted answer, it did not fulfill all of my unit tests. The issue for me is when you have a new object, with Start and End dates and you have to set the Start date ( at this stage your End date has the minimum date value of 01/01/0001) - this solution did pass all my unit tests:

    public DateTime Start
    {
        get { return _start; }
        set
        {
            if (_end.Equals(DateTime.MinValue))
            {
                _start = value;
            }
            else if (value.Date < _end.Date)
            {
                _start = value;
            }
            else
            {
                throw new ArgumentException("Start date must be before the End date.");
            }
        }
    }


    public DateTime End
    {
        get { return _end; }
        set
        {
            if (_start.Equals(DateTime.MinValue))
            {
                _end = value;
            }
            else if (value.Date > _start.Date)
            {
                _end = value;
            }
            else
            {
                throw new ArgumentException("End date must be after the Start date.");
            }
        }
    }

It does miss the edge case where both Start and End dates can be 01/01/0001 but I'm not concerned about that.

I've had this problem twice. The first problem was fixed using the marked answer on this page (thank you for that). However, the second time proved a bit more difficult.

I found that in my httpd-vhosts.conf file that I made a mistake when assigning the document root to a domain name. Fixing this solved my problem. It is well worth checking (or even reverting to a blank copy) your httpd-vhosts.conf file for any errors and typo's.

The following line is looking for the exact NavigableString 'Python':

>>> soup.body.findAll(text='Python')
[]

Note that the following NavigableString is found:

>>> soup.body.findAll(text='Python Jobs') 
[u'Python Jobs']

Note this behaviour:

>>> import re
>>> soup.body.findAll(text=re.compile('^Python$'))
[]

So your regexp is looking for an occurrence of 'Python' not the exact match to the NavigableString 'Python'.

If you're meaning to make a server call from the client, you should use Ajax - look at something like Jquery and use $.Ajax() or $.getJson() to call the server function, depending on what kind of return you're after or action you want to execute.

In mathematics, there are sets and ordered sets (osets).

• set: an unordered container of unique elements (Implemented)
• oset: an ordered container of unique elements (NotImplemented)

In Python, only sets are directly implemented. We can emulate osets with regular dict keys (3.7+).

Given

a = [1, 2, 20, 6, 210, 2, 1]
b = {2, 6}

Code

oset = dict.fromkeys(a).keys()
# dict_keys([1, 2, 20, 6, 210])

Demo

Replicates are removed, insertion-order is preserved.

list(oset)
# [1, 2, 20, 6, 210]

Set-like operations on dict keys.

oset - b
# {1, 20, 210}

oset | b
# {1, 2, 5, 6, 20, 210}

oset & b
# {2, 6}

oset ^ b
# {1, 5, 20, 210}

Details

Note: an unordered structure does not preclude ordered elements. Rather, maintained order is not guaranteed. Example:

assert {1, 2, 3} == {2, 3, 1}                    # sets (order is ignored)

assert [1, 2, 3] != [2, 3, 1]                    # lists (order is guaranteed)

One may be pleased to discover that a list and multiset (mset) are two more fascinating, mathematical data structures:

• list: an ordered container of elements that permits replicates (Implemented)
• mset: an unordered container of elements that permits replicates (NotImplemented)*

Summary

Container | Ordered | Unique | Implemented
----------|---------|--------|------------
set       |    n    |    y   |     y
oset      |    y    |    y   |     n
list      |    y    |    n   |     y
mset      |    n    |    n   |     n*  

^{*A multiset can be indirectly emulated with collections.Counter(), a dict-like mapping of multiplicities (counts).}

You can infinitely loop easily enough via recursion.

function it_keeps_going_and_going_and_going() {
  it_keeps_going_and_going_and_going();
}

it_keeps_going_and_going_and_going()

Could use the following and then explode the post result explode(",", $_POST['data']); to give an array of results.

var data = new Array();
$("input[name='checkBoxesName']:checked").each(function(i) {
    data.push($(this).val());
});

Simply add style="line-height:0" to each cell. This works in IE because it sets the line-height of both existant and non-existant text to about 19px and that forces the cells to expand vertically in most versions of IE. Regardless of whether or not you have text this needs to be done for IE to correctly display rows less than 20px high.

Because if you want to trigger your data with deep of it,you have to pass 3th argument true of your listener.By default it's false and it meens that you function will trigger,only when your variable will change not it's field.

Not exactly what you want, but close to it:

var jscriptVersion = /*@cc_on @if(@_jscript) @_jscript_version @else @*/ false /*@end @*/;
var geckoVersion = navigator.product === 'Gecko' && navigator.productSub;
var operaVersion = 'opera' in window && 'version' in opera && opera.version();

The variables will contain the appropriate version or false if it is not available.

I'd appreciate it if someone using Chrome could find out if you can use window.chrome in a similar way to window.opera.

Something like this (not tested)

with match_groups as (

  select product_id, 
         matching_product_id,
         product_id as group_id
  from matches
  where product_id not in (select matching_product_id from matches)

  union all

  select m.product_id, m.matching_product_id, p.group_id
  from matches m
    join match_groups p on m.product_id = p.matching_product_id
)
select group_id, product_id
from match_groups
order by group_id;

JavaScript has Function-Level variable scope which means you will have to declare your variable outside $(document).ready() function.

Or alternatively to make your variable to have global scope, simply dont use var keyword before it like shown below. However generally this is considered bad practice because it pollutes the global scope but it is up to you to decide.

$(document).ready(function() {
   intro = null; // it is in global scope now

• Explaining JavaScript Scope And Closures

You need to include the following lines in your docker-compose.yml:

version: "3"
services:
  app:
    image: app:1.2.3
    stdin_open: true # docker run -i
    tty: true        # docker run -t

The first corresponds to -i in docker run and the second to -t.

My guess is that with VWD your solutions are more likely to be deployed to third party servers, many of which do not allow for a dynamically attached SQL Server database file. Thus the allowing of the other connection type.

This difference in IDE behavior is one of the key reasons for upgrading to a full version.

It would seem that _AMD64_ is not defined, since I can't imagine you are compiling for Itanium (_IA64_).

Package organization or package structuring is usually a heated discussion. Below are some simple guidelines for package naming and structuring:

• Follow java package naming conventions
• Structure your packages according to their functional role as well as their business role
  • Break down your packages according to their functionality or modules. e.g. com.company.product.modulea
  • Further break down could be based on layers in your software. But don't go overboard if you have only few classes in the package, then it makes sense to have everything in the package. e.g. com.company.product.module.web or com.company.product.module.util etc.
  • Avoid going overboard with structuring, IMO avoid separate packaging for exceptions, factories, etc. unless there's a pressing need.
• If your project is small, keep it simple with few packages. e.g. com.company.product.model and com.company.product.util, etc.
• Take a look at some of the popular open source projects out there on Apache projects. See how they use structuring, for various sized projects.
• Also consider build and distribution when naming ( allowing you to distribute your api or SDK in a different package, see servlet api)

After a few experiments and trials you should be able to come up with a structuring that you are comfortable with. Don't be fixated on one convention, be open to changes.

In this particular case, the solution was the right proxy configuration of eclipse (Window -> Preferences -> Network Connection), the company possessed a strict security system. I will leave the question, because there are answers that can help the community. Thank you very much for the answers above.

TryGetValue will already assign the default value for the type to the dictionary, so you can just use:

dictionary.TryGetValue(key, out value);

and just ignore the return value. However, that really will just return default(TValue), not some custom default value (nor, more usefully, the result of executing a delegate). There's nothing more powerful built into the framework. I would suggest two extension methods:

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary, 
     TKey key,
     TValue defaultValue)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value : defaultValue;
}

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary,
     TKey key,
     Func<TValue> defaultValueProvider)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value
         : defaultValueProvider();
}

(You may want to put argument checking in, of course :)

Use int64_t, that portable C99 code.

int64_t var = 0x0000444400004444LL;

For printing:

#define __STDC_FORMAT_MACROS
#include <inttypes.h>

printf("blabla %" PRIi64 " blabla\n", var);

First of all, please make sure your Database server is up and running. I was getting the same error, after trying all the answers listed here I found out that my Database server was not running.

You can check the same from MySQL Workbench, or Command line using

mysql -u USERNAME -p

This sounds obvious, but many times we assume that Database server is up and running all the time, especially when we are working on our local machine, when we restart/shutdown the machine, Database server will be shutdown automatically.

Add some code to the Form Load event:

me.maximumsize = new size(Width, Height)
me.minimumsize = me.maximumsize
me.maximizebox = false
me.minimizebox = false

Example: For a Form height and width of 50 pixels each:

me.maximumsize = new size(50, 50)
me.minimumsize = me.maximumsize
me.maximizebox = false
me.minimizebox = false

Note that setting maximumsize and minimumsize to the same size as shown here prevents resizing the Form.

Set objShell = WScript.CreateObject("WScript.Shell") 
skey = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{9A25302D-30C0-39D9-BD6F-21E6EC160475}\"
with CreateObject("WScript.Shell")
    on error resume next            ' turn off error trapping
    sValue = .regread(sKey)       ' read attempt
    bFound = (err.number = 0)     ' test for success
end with
if bFound then
    msgbox "exists"
else
  msgbox "not exists" 
End If

I've found the same thing, but only on emulators that have the Use Host GPU setting ticked. Try turning that off, you'll no longer see those warnings (and the emulator will run horribly, horribly slowly..)

In my experience those warnings are harmless. Notice that the "error" is EGL_SUCCESS, which would seem to indicate no error at all!

The child selector > does not work in IE6.

Providing you know the index value of the beginning and end of each word you wish to replace in the character array, and you only wish to replace that particular chunk of data, you could do it like this.

>>> s = "papa is papa is papa"
>>> s = s[:8]+s[8:13].replace("papa", "mama")+s[13:]
>>> print(s)
papa is mama is papa

Alternatively, if you also wish to retain the original data structure, you could store it in a dictionary.

>>> bin = {}
>>> s = "papa is papa is papa"
>>> bin["0"] = s
>>> s = s[:8]+s[8:13].replace("papa", "mama")+s[13:]
>>> print(bin["0"])
papa is papa is papa
>>> print(s)
papa is mama is papa

I found that the easiest way is:

1. Add an Icon file into your WinForms project.
2. Change the icon files' build action into Embedded Resource

3. In the Main Form Load function:

   Icon = LoadIcon("< the file name of that icon file >");

Tensorflow 2.0 Compatible Answer: The explanations of dga and stackoverflowuser2010 are very detailed about Logits and the related Functions.

All those functions, when used in Tensorflow 1.x will work fine, but if you migrate your code from 1.x (1.14, 1.15, etc) to 2.x (2.0, 2.1, etc..), using those functions result in error.

Hence, specifying the 2.0 Compatible Calls for all the functions, we discussed above, if we migrate from 1.x to 2.x, for the benefit of the community.

Functions in 1.x:

1. tf.nn.softmax
2. tf.nn.softmax_cross_entropy_with_logits
3. tf.nn.sparse_softmax_cross_entropy_with_logits

Respective Functions when Migrated from 1.x to 2.x:

1. tf.compat.v2.nn.softmax
2. tf.compat.v2.nn.softmax_cross_entropy_with_logits
3. tf.compat.v2.nn.sparse_softmax_cross_entropy_with_logits

Many DOS commands in the different versions of Windows are similar but may support different parameters. Plus, newer versions of Windows may support new commands or retire older ones. Thus, if you wish to write a batch file that can run on different types of machines, it may prove beneficial to determine the version of Windows on which the batch file is running. This way the batch file can execute commands appropriate to the operating system.

The following batch file will determine whether or not the machine is running Windows 7, Windows Server 2008, Windows Vista, Windows Server 2003, Windows XP, Windows 2000, or Windows NT. It can easily be modified to support other versions of Windows as necessary or to set an environment variable based on the version of Windows detected. Note that for this batch file to correctly discern between newer versions of Windows Server and consumer versions of Windows, it is more convoluted than batch files you may see elsewhere. I have explained the reasoning below.

1) Open a Notepad window.

2) Copy the following text into Notepad (you may want to access this tip's printed version as some lines wrap):

@echo off

ver | find "2003" > nul
if %ERRORLEVEL% == 0 goto ver_2003

ver | find "XP" > nul
if %ERRORLEVEL% == 0 goto ver_xp

ver | find "2000" > nul
if %ERRORLEVEL% == 0 goto ver_2000

ver | find "NT" > nul
if %ERRORLEVEL% == 0 goto ver_nt

if not exist %SystemRoot%\system32\systeminfo.exe goto warnthenexit

systeminfo | find "OS Name" > %TEMP%\osname.txt
FOR /F "usebackq delims=: tokens=2" %%i IN (%TEMP%\osname.txt) DO set vers=%%i

echo %vers% | find "Windows 7" > nul
if %ERRORLEVEL% == 0 goto ver_7

echo %vers% | find "Windows Server 2008" > nul
if %ERRORLEVEL% == 0 goto ver_2008

echo %vers% | find "Windows Vista" > nul
if %ERRORLEVEL% == 0 goto ver_vista

goto warnthenexit

:ver_7
:Run Windows 7 specific commands here.
echo Windows 7
goto exit

:ver_2008
:Run Windows Server 2008 specific commands here.
echo Windows Server 2008
goto exit

:ver_vista
:Run Windows Vista specific commands here.
echo Windows Vista
goto exit

:ver_2003
:Run Windows Server 2003 specific commands here.
echo Windows Server 2003
goto exit

:ver_xp
:Run Windows XP specific commands here.
echo Windows XP
goto exit

:ver_2000
:Run Windows 2000 specific commands here.
echo Windows 2000
goto exit

:ver_nt
:Run Windows NT specific commands here.
echo Windows NT
goto exit

:warnthenexit
echo Machine undetermined.

:exit

3) Save the file as %WINDIR%\whichvers.bat

4) Now, from the command prompt, enter:

whichvers

This will display which version of Windows you are running.

NOTES:

1. The reasoning for using the SYSTEMINFO command rather than relying on the VER command is because Windows Server 2008 "shares" version numbers with other Windows releases (see Microsoft). Thus relying on a "version number" of 6.0 to detect Windows Vista or 6.1 to detect Windows 7 fails to differentiate a machine from Windows Server 2008 or Windows Server 2008 R2.

2. The creation of %TEMP%\osname.txt is solely because I could not place the results of systeminfo | find "OS Name" directly into the for /f command - it does not like piped commands. You may find an easier way to handle grabbing the information from SYSTEMINFO - if so, please comment.

3. The environment variable %vers% has leading spaces. I could remove these with a longer batch file, but in this case it is not necessary.

4. The batch file detects for SYSTEMINFO as it assumes if it gets beyond the older operating system detections, the running version of Windows is even older and will not have this utility. On Windows 7 64-bit it is still located in the %SystemRoot%\system32 folder - if later versions of Windows become 64-bit only, this batch file may have to be updated.

Return to the Windows XP and DOS page.

This might be easier to explain with a sample dataset.

Create Sample Data

Let's assume we have a single column of Timestamps, date and another column we would like to perform an aggregation on, a.

df = pd.DataFrame({'date':pd.DatetimeIndex(['2012-1-1', '2012-6-1', '2015-1-1', '2015-2-1', '2015-3-1']),
                   'a':[9,5,1,2,3]}, columns=['date', 'a'])

df

        date  a
0 2012-01-01  9
1 2012-06-01  5
2 2015-01-01  1
3 2015-02-01  2
4 2015-03-01  3

There are several ways to group by year

• Use the dt accessor with year property
• Put date in index and use anonymous function to access year
• Use resample method
• Convert to pandas Period

.dt accessor with year property

When you have a column (and not an index) of pandas Timestamps, you can access many more extra properties and methods with the dt accessor. For instance:

df['date'].dt.year

0    2012
1    2012
2    2015
3    2015
4    2015
Name: date, dtype: int64

We can use this to form our groups and calculate some aggregations on a particular column:

df.groupby(df['date'].dt.year)['a'].agg(['sum', 'mean', 'max'])

      sum  mean  max
date                
2012   14     7    9
2015    6     2    3

put date in index and use anonymous function to access year

If you set the date column as the index, it becomes a DateTimeIndex with the same properties and methods as the dt accessor gives normal columns

df1 = df.set_index('date')
df1.index.year

Int64Index([2012, 2012, 2015, 2015, 2015], dtype='int64', name='date')

Interestingly, when using the groupby method, you can pass it a function. This function will be implicitly passed the DataFrame's index. So, we can get the same result from above with the following:

df1.groupby(lambda x: x.year)['a'].agg(['sum', 'mean', 'max'])

      sum  mean  max
2012   14     7    9
2015    6     2    3

Use the resample method

If your date column is not in the index, you must specify the column with the on parameter. You also need to specify the offset alias as a string.

df.resample('AS', on='date')['a'].agg(['sum', 'mean', 'max'])

             sum  mean  max
date                       
2012-01-01  14.0   7.0  9.0
2013-01-01   NaN   NaN  NaN
2014-01-01   NaN   NaN  NaN
2015-01-01   6.0   2.0  3.0

Convert to pandas Period

You can also convert the date column to a pandas Period object. We must pass in the offset alias as a string to determine the length of the Period.

df['date'].dt.to_period('A')

0   2012
1   2012
2   2015
3   2015
4   2015
Name: date, dtype: object

We can then use this as a group

df.groupby(df['date'].dt.to_period('Y'))['a'].agg(['sum', 'mean', 'max'])


      sum  mean  max
2012   14     7    9
2015    6     2    3

The inspect.isclass is probably the best solution, and it's really easy to see how it's actually implemented

def isclass(object):
    """Return true if the object is a class.

    Class objects provide these attributes:
        __doc__         documentation string
        __module__      name of module in which this class was defined"""
    return isinstance(object, (type, types.ClassType))

It is recommended that you create a file named setenv.bat and place it in the Tomcat bin directory. With this file (which is run by the catalina.bat and catalina.sh scripts), you can change the following Tomcat environment settings with the JAVA_OPTS variable:

You can set the minimum and maximum memory heap size with the

JVM -Xms and -Xmx parameters.

The best limits depend on many conditions, such as transformations that Integrator ETL should execute. For Information Discovery transformations, a maximum of 1 GB is recommended. For example, to set the minimum heap size to 128 MB and the maximum heap size to 1024 MB, use

JAVA_OPTS=-Xms128m -Xmx1024m        

You should set the maximum limit of the PermGen (Permanent Generation) memory space to a size larger than the default. The default of 64 MB is not enough for enterprise applications. A suitable memory limit depends on various criteria, but 256 MB would make a good choice in most cases. If the PermGen space maximum is too low, OutOfMemoryError: PermGen space errors may occur. You can set the PermGen maximum limit with the following JVM parameter

    -XX:MaxPermSize=256m

For performance reasons, it is recommended that the application is run in Server mode. Apache Tomcat does not run in Server mode by default. You can set the Server mode by using the JVM -server parameter. You can set the JVM parameter in the JAVA_OPTS variable in the environment variable in the setenv file.

The following is an example of a setenv.bat file:

set "JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx1024m -XX:MaxPermSize=256m -server"

A somewhat clumsy ascii-art to demonstrate the mechanism: The join() is presumably called by the main-thread. It could also be called by another thread, but would needlessly complicate the diagram.

join-calling should be placed in the track of the main-thread, but to express thread-relation and keep it as simple as possible, I choose to place it in the child-thread instead.

without join:

  +,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,     child-thread(long + daemonized)

'-' main-thread/parent-thread/main-program execution
'.' child-thread execution
'#' optional parent-thread execution after join()-blocked parent-thread could 
    continue
'*' main-thread 'sleeping' in join-method, waiting for child-thread to finish
',' daemonized thread - 'ignores' lifetime of other threads;
    terminates when main-programs exits; is normally meant for 
    join-independent tasks

So the reason you don't see any changes is because your main-thread does nothing after your join. You could say join is (only) relevant for the execution-flow of the main-thread.

If, for example, you want to concurrently download a bunch of pages to concatenate them into a single large page, you may start concurrent downloads using threads, but need to wait until the last page/thread is finished before you start assembling a single page out of many. That's when you use join().

Simple:

  public static String decToHex(int dec)
  {
        return Integer.toHexString(dec);
  }

As mentioned here: Java Convert integer to hex integer

Yes. you can use SimpleDateFormat like this.

SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));

Output OldDate-->2011-03-10T11:54:30.207Z NewDate-->10-Mar-2011 11:54:30.207

Many of the answerers spotted the issue and already gave the solution.

I just want to suggest another solution, which is changing the Glogal variable value from within the tool Mysql Workbench. That is ofcourse IF you use Workbench running locally on server (or via SSH connection)

You just connect to your instance and go on menu:

Server -> Options File -> Networking -> max_allowed_packed

You set the desired value and then you need to restart MySql Service.

If you mean milliseconds since epoch you could do

ptime time_t_epoch(date(1970,1,1)); 
ptime now = microsec_clock::local_time();
time_duration diff = now - time_t_epoch;
x = diff.total_milliseconds();

However, it's not particularly clear what you're after.

Have a look at the example in the documentation for DateTime at Boost Date Time

I installed 2 and 3 and had the same problem finding 3. Fortunately, typing path at the windows path let me find where I had installed it. The path was an option when I installed Python which I just forgot. If you didn't select setting the path when you installed Python 3 that probably won't work - unless you manually updated the path when you installed it. In my case it was at c:\Program Files\Python37\python.exe

You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh

open new terminal and validate environment is clean from old RVM settings (should be no output):

env | grep rvm

if there was output, try to open new terminal, if it does not help then restart your computer.

install RVM:

\curl -L https://get.rvm.io | 
  bash -s stable --ruby --autolibs=enable --auto-dotfiles

If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04, which gives a bit more explanation.

I tend to find that if I'm specifying individual colours in multiple geom's, I'm doing it wrong. Here's how I would plot your data:

##Subset the necessary columns
dd_sub = datos[,c(20, 2,3,5)]
##Then rearrange your data frame
library(reshape2)
dd = melt(dd_sub, id=c("fecha"))

All that's left is a simple ggplot command:

ggplot(dd) + geom_line(aes(x=fecha, y=value, colour=variable)) +
  scale_colour_manual(values=c("red","green","blue"))

Example plot

public class MainActivity extends AppCompatActivity  implements View.OnClickListener{

    Button b1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        b1=(Button)findViewById(R.id.button);
        b1.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        Toast.makeText(getApplicationContext(),"Button is Working",Toast.LENGTH_LONG).show();
    }

}

It does not work because your script in JSFiddle is running inside it's own scope (see the "OnLoad" drop down on the left?).

One way around this is to bind your event handler in javascript (where it should be):

document.getElementById('optionID').onchange = function () {
    document.getElementById("message").innerHTML = "Having a Baby!!";
};

Another way is to modify your code for the fiddle environment and explicitly declare your function as global so it can be found by your inline event handler:

window.changeMessage() {
    document.getElementById("message").innerHTML = "Having a Baby!!";
};

?

Just use queuecomplete that's what its there for and its so so simple. Check the docs http://www.dropzonejs.com/

queuecomplete > Called when all files in the queue finished uploading.

      this.on("queuecomplete", function (file) {
          alert("All files have uploaded ");
      });

You want to git rebase -i to perform an interactive rebase.

If you're currently on your "commit 1", and the commit you want to merge, "commit 2", is the previous commit, you can run git rebase -i HEAD~2, which will spawn an editor listing all the commits the rebase will traverse. You should see two lines starting with "pick". To proceed with squashing, change the first word of the second line from "pick" to "squash". Then save your file, and quit. Git will squash your first commit into your second last commit.

Note that this process rewrites the history of your branch. If you are pushing your code somewhere, you'll have to git push -f and anybody sharing your code will have to jump through some hoops to pull your changes.

Note that if the two commits in question aren't the last two commits on the branch, the process will be slightly different.

The 'c' means it's a character device. tty is a special file representing the 'controlling terminal' for the current process.

Character Devices

Unix supports 'device files', which aren't really files at all, but file-like access points to hardware devices. A 'character' device is one which is interfaced byte-by-byte (as opposed to buffered IO).

TTY

/dev/tty is a special file, representing the terminal for the current process. So, when you echo 1 > /dev/tty, your message ('1') will appear on your screen. Likewise, when you cat /dev/tty, your subsequent input gets duplicated (until you press Ctrl-C).

/dev/tty doesn't 'contain' anything as such, but you can read from it and write to it (for what it's worth). I can't think of a good use for it, but there are similar files which are very useful for simple IO operations (e.g. /dev/ttyS0 is normally your serial port)

This quote is from http://tldp.org/HOWTO/Text-Terminal-HOWTO-7.html#ss7.3 :

/dev/tty stands for the controlling terminal (if any) for the current process. To find out which tty's are attached to which processes use the "ps -a" command at the shell prompt (command line). Look at the "tty" column. For the shell process you're in, /dev/tty is the terminal you are now using. Type "tty" at the shell prompt to see what it is (see manual pg. tty(1)). /dev/tty is something like a link to the actually terminal device name with some additional features for C-programmers: see the manual page tty(4).

Here is the man page: http://linux.die.net/man/4/tty

async and defer will download the file during HTML parsing. Both will not interrupt the parser.

• The script with async attribute will be executed once it is downloaded. While the script with defer attribute will be executed after completing the DOM parsing.

• The scripts loaded with async doesn't guarantee any order. While the scripts loaded with defer attribute maintains the order in which they appear on the DOM.

Use <script async> when the script does not rely on anything. when the script depends use <script defer>.

Best solution would be add the <script> at the bottom of the body. There will be no issue with blocking or rendering.

A common PyTorch convention is to save models using either a .pt or .pth file extension.

Save/Load Entire Model Save:

path = "username/directory/lstmmodelgpu.pth"
torch.save(trainer, path)

Load:

Model class must be defined somewhere

model = torch.load(PATH)
model.eval()

You can write an object to a file using writeObject in ObjectOutputStream

ObjectOutputStream

I got this error too even I ran cmd as an Administrator.

The root cause is: The file is from VCS(subversion, perforce, etc.), and when I checked the properties of this file, its' Attributes is Read-only.

So the solution is:

• (1) disable the 'Read-only' Attribute;
• (2) check out from VCS, let the file under the status of read&write.

Web.xml is called as deployment descriptor file and its is is an XML file that contains information on the configuration of the web application, including the configuration of servlets.

It can also be used as below:

from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)

Building on rq's answer, I found this line does what I want:

git grep "search for something" $(git log -g --pretty=format:%h -S"search for something")

Which will report the commit ID, filename, and display the matching line, like this:

91ba969:testFile:this is a test

... Does anyone agree that this would be a nice option to be included in the standard git grep command?

I just tried to use ranges from bigger to smaller amount and got the result I didn't expect:

irb(main):007:0> Array(1..5)
=> [1, 2, 3, 4, 5]
irb(main):008:0> Array(5..1)
=> []

That's because of ranges implementations.
So I had to use the following option:

(1..5).to_a.reverse

List<String> stringList = integerList.stream().map((Object s)->String.valueOf(s)).collect(Collectors.toList())

I'm using Visual Studio 2017 Community Edition.
I solved this problem by making a directory called tessdata in the Debug directory of my project. Then I put the eng.traineddata file into said directory.

If you want to check if an object is within in array by checking an attribute on the object, you can use any? and pass a block that evaluates to true or false:

unless @suggested_horses.any? {|h| h.id == horse.id }
  @suggested_horses << horse
end

In your PhP file there's going to be a variable called $_REQUEST and it contains an array with all the data send from Javascript to PhP using AJAX.

Try this: var_dump($_REQUEST); and check if you're receiving the values.

This is a few months late, but I have created PR#6251 with matplotlib to add a new PercentFormatter class. With this class you just need one line to reformat your axis (two if you count the import of matplotlib.ticker):

import ...
import matplotlib.ticker as mtick

ax = df['myvar'].plot(kind='bar')
ax.yaxis.set_major_formatter(mtick.PercentFormatter())

PercentFormatter() accepts three arguments, xmax, decimals, symbol. xmax allows you to set the value that corresponds to 100% on the axis. This is nice if you have data from 0.0 to 1.0 and you want to display it from 0% to 100%. Just do PercentFormatter(1.0).

The other two parameters allow you to set the number of digits after the decimal point and the symbol. They default to None and '%', respectively. decimals=None will automatically set the number of decimal points based on how much of the axes you are showing.

Update

PercentFormatter was introduced into Matplotlib proper in version 2.1.0.

I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.

REST

It is neither an API nor a framework. It is just an architectural concept. You can find more details here.

RESTful

I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.

EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.

Web API

It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).

Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.

SELECT left(NAME, charindex('_', NAME) - 1)
FROM tempdb..sysobjects
WHERE NAME LIKE '#%'
    AND NAME NOT LIKE '##%'
    AND upper(xtype) = 'U'
    AND NOT object_id('tempdb..' + NAME) IS NULL

you can remove the ## line if you want to include global temp tables.

In my case:

• The phone was connected as a media device.
• Clicked on that message and got a menu. "USB computer connection"
• In that menu chose to connect it as a camera (for devices that do not support MTP)

And then it worked.

This happened to me because I had moved the following line close to the beginning of the .csproj file:

  <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets"/>

It needs to be placed after the PropertyGroups that define your Configuration|Platform.

You can check if you got your remote setup right and have the proper permissions with

git ls-remote origin

if you called your remote "origin". If you get an error you probably don't have your security set up correctly such as uploading your public key to github for example. If things are setup correctly, you will get a list of the remote references. Now

git fetch origin

will work barring any other issues like an unplugged network cable.

Once you have that done, you can get any branch you want that the above command listed with

git checkout some-branch

this will create a local branch of the same name as the remote branch and check it out.

Accepted answer is right, however I had a trouble with that. When I add in my code, checking on debugger, I saw that it changes from

result.replace(/"/g,'"')

to

result.replace(/"/g,'"')

Instead of this I use that:

result.replace(/(&quot\;)/g,"\"")

By this notation it works.

I had used home-brew to install 2.7 on OS X 10.10 and the new install was missing the sym links. I ran

brew link --overwrite python

as mentioned in How to symlink python in Homebrew? and it solved the problem.

Take a look at algorithms package, especially the algorithm environment.

Does this work?

Workbooks.Open Filename:=filepath, ReadOnly:=True

Or, as pointed out in a comment, to keep a reference to the opened workbook:

Dim book As Workbook
Set book = Workbooks.Open(Filename:=filepath, ReadOnly:=True)

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

My solution;

Ubuntu 18.04 (WSL)

/etc/mysql/my.cnf

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/

/etc/mysql/mysql.conf.d/mysqld.cnf

[mysqld]
user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            = 3306

I changed the port. It's worked for me. You can write another port. Example 3355

With the latest aws-cli python command line tools, to recursively delete all the files under a folder in a bucket is just:

aws s3 rm --recursive s3://your_bucket_name/foo/

Or delete everything under the bucket:

aws s3 rm --recursive s3://your_bucket_name

If what you want is to actually delete the bucket, there is one-step shortcut:

aws s3 rb --force s3://your_bucket_name

which will remove the contents in that bucket recursively then delete the bucket.

Note: the s3:// protocol prefix is required for these commands to work

i think the most proper way is to use the same piece of code angular use when doing a "get" request using you $httpParamSerializer will have to inject it to your controller so you can simply do the following without having to use Jquery at all , $http.post(url,$httpParamSerializer({param:val}))

app.controller('ctrl',function($scope,$http,$httpParamSerializer){
  $http.post(url,$httpParamSerializer({param:val,secondParam:secondVal}));
}

Json.NET has a JsonPropertyAttribute which allows you to specify the name of a JSON property, so your code should be:

public class TeamScore
{
    [JsonProperty("eighty_min_score")]
    public string EightyMinScore { get; set; }
    [JsonProperty("home_or_away")]
    public string HomeOrAway { get; set; }
    [JsonProperty("score ")]
    public string Score { get; set; }
    [JsonProperty("team_id")]
    public string TeamId { get; set; }
}

public class Team
{
    public string v1 { get; set; }
    [JsonProperty("attributes")]
    public TeamScore TeamScores { get; set; }
}

public class RootObject
{
    public List<Team> Team { get; set; }
}

Documentation: Serialization Attributes

I had a similar issue and ended up hooking and event

ng-change="changeCount()" 

then:

self.changeCount = function () {
      if (!self.info.itemcount) {
        self.info.itemcount = 1;
      }
 };

So the user is defaulted to 1 if a invalid number is inserted.

I have created a Swift extension based on @Dima solution:

extension UIImage {
    class func imageWithView(view: UIView) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0)
        view.drawViewHierarchyInRect(view.bounds, afterScreenUpdates: true)
        let img = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return img
    }
}

EDIT: Swift 4 improved version

extension UIImage {
    class func imageWithView(_ view: UIView) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.isOpaque, 0)
        defer { UIGraphicsEndImageContext() }
        view.drawHierarchy(in: view.bounds, afterScreenUpdates: true)
        return UIGraphicsGetImageFromCurrentImageContext() ?? UIImage()
    }
}

Usage:

let view = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))  
let image = UIImage.imageWithView(view)

This is not JSON. JSON was designed to be simple; allowing arbitrary expressions is not simple.

In full JavaScript, I don't think you can do this directly. You cannot refer to this until the object called obj is fully constructed. So you need a workaround, that someone with more JavaScript-fu than I will provide.

This is how I did this on an existing table and column (named id):

UPDATE table SET id=ROWNUM;
DECLARE
  maxval NUMBER;
BEGIN
  SELECT MAX(id) INTO maxval FROM table;
  EXECUTE IMMEDIATE 'DROP SEQUENCE table_seq';
  EXECUTE IMMEDIATE 'CREATE SEQUENCE table_seq START WITH '|| TO_CHAR(TO_NUMBER(maxval)+1) ||' INCREMENT BY 1 NOMAXVALUE';
END;
CREATE TRIGGER table_trigger
  BEFORE INSERT ON table
  FOR EACH ROW
BEGIN
  :new.id := table_seq.NEXTVAL;
END;

I was recently dealing with an issue when I was trying to get past authentication while making a REST call from Java, and while the answers in this thread (and other threads) helped, there was still a bit of trial and error involved in getting it working.

What worked for me was encoding credentials in Base64 and adding them as Basic Authorization headers. I then added them as an HttpEntity to restTemplate.postForEntity, which gave me the response I needed.

Here's the class I wrote for this in full (extending RestTemplate):

public class AuthorizedRestTemplate extends RestTemplate{

    private String username;
    private String password;

    public AuthorizedRestTemplate(String username, String password){
        this.username = username;
        this.password = password;
    }

    public String getForObject(String url, Object... urlVariables){
        return authorizedRestCall(this, url, urlVariables);
    }

    private String authorizedRestCall(RestTemplate restTemplate, 
            String url, Object... urlVariables){
        HttpEntity<String> request = getRequest();
        ResponseEntity<String> entity = restTemplate.postForEntity(url, 
                request, String.class, urlVariables);
        return entity.getBody();
    }

    private HttpEntity<String> getRequest(){
        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic " + getBase64Credentials());
        return new HttpEntity<String>(headers);
    }

    private String getBase64Credentials(){
        String plainCreds = username + ":" + password;
        byte[] plainCredsBytes = plainCreds.getBytes();
        byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
        return new String(base64CredsBytes);
    }
}

If you have installed mongodb community server via homebrew, then you can do:

brew services list

This will list the current services as below:

Name              Status  User          Plist
mongodb-community started thehaystacker /Users/thehaystacker/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist

redis             stopped

Then you can restart mongodb by first stopping and restart:

brew services stop mongodb
brew services start mongodb

xkr.us has a great discussion, with examples. To quote their summary:

The escape() method does not encode the + character which is interpreted as a space on the server side as well as generated by forms with spaces in their fields. Due to this shortcoming and the fact that this function fails to handle non-ASCII characters correctly, you should avoid use of escape() whenever possible. The best alternative is usually encodeURIComponent().

escape() will not encode: @*/+

Use of the encodeURI() method is a bit more specialized than escape() in that it encodes for URIs as opposed to the querystring, which is part of a URL. Use this method when you need to encode a string to be used for any resource that uses URIs and needs certain characters to remain un-encoded. Note that this method does not encode the ' character, as it is a valid character within URIs.

encodeURI() will not encode: ~!@#$&*()=:/,;?+'

Lastly, the encodeURIComponent() method should be used in most cases when encoding a single component of a URI. This method will encode certain chars that would normally be recognized as special chars for URIs so that many components may be included. Note that this method does not encode the ' character, as it is a valid character within URIs.

encodeURIComponent() will not encode: ~!*()'

The answer is very simple. write the below code

import { Component, OnInit, OnDestroy, Input } from "@angular/core";
// Import this, and write at the top of your .ts file
import { HostListener } from "@angular/core";

@Component({
 selector: "app-login",
 templateUrl: './login.component.html',
 styleUrls: ['./login.component.css']
})

export class LoginComponent implements OnInit, OnDestroy {
// Declare height and width variables
scrHeight:any;
scrWidth:any;

@HostListener('window:resize', ['$event'])
getScreenSize(event?) {
      this.scrHeight = window.innerHeight;
      this.scrWidth = window.innerWidth;
      console.log(this.scrHeight, this.scrWidth);
}

// Constructor
constructor() {
    this.getScreenSize();
}
}

To make it easier for yourself you could also create an actionfilterattribute

public class AllowJsonGetAttribute : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        var jsonResult = filterContext.Result as JsonResult;

        if (jsonResult == null)
            throw new ArgumentException("Action does not return a JsonResult, 
                                                   attribute AllowJsonGet is not allowed");

        jsonResult.JsonRequestBehavior = JsonRequestBehavior.AllowGet;            

        base.OnResultExecuting(filterContext);
    }
}

and use it on your action

[AllowJsonGet]
public JsonResult MyAjaxAction()
{
    return Json("this is my test");
}

No one said, but array_push only pushes a element to the END OF THE ARRAY, where $array[index] can insert a value at any given index. Big difference.

Run in a shell loop, example:

#!/bin/sh    
counter=1
while true ; do
 echo $counter
 counter=$((counter+1))
 if [[ "$counter" -eq 60 ]]; then
  counter=0
 fi
 wget -q http://localhost/tool/heartbeat/ -O - > /dev/null 2>&1 &
 sleep 1
done

Here is a full example which reads the contents of the given web page. The web page is read from an HTML form. We use standard InputStream classes, but it could be done more easily with JSoup library.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>

</dependency>

<dependency>
    <groupId>commons-validator</groupId>
    <artifactId>commons-validator</artifactId>
    <version>1.6</version>
</dependency>  

These are the Maven dependencies. We use Apache Commons library to validate URL strings.

package com.zetcode.web;

import com.zetcode.service.WebPageReader;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet(name = "ReadWebPage", urlPatterns = {"/ReadWebPage"})
public class ReadWebpage extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        response.setContentType("text/plain;charset=UTF-8");

        String page = request.getParameter("webpage");

        String content = new WebPageReader().setWebPageName(page).getWebPageContent();

        ServletOutputStream os = response.getOutputStream();
        os.write(content.getBytes(StandardCharsets.UTF_8));
    }
}

The ReadWebPage servlet reads the contents of the given web page and sends it back to the client in plain text format. The task of reading the page is delegated to WebPageReader.

package com.zetcode.service;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.nio.charset.StandardCharsets;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.stream.Collectors;
import org.apache.commons.validator.routines.UrlValidator;

public class WebPageReader {

    private String webpage;
    private String content;

    public WebPageReader setWebPageName(String name) {

        webpage = name;
        return this;
    }

    public String getWebPageContent() {

        try {

            boolean valid = validateUrl(webpage);

            if (!valid) {

                content = "Invalid URL; use http(s)://www.example.com format";
                return content;
            }

            URL url = new URL(webpage);

            try (InputStream is = url.openStream();
                    BufferedReader br = new BufferedReader(
                            new InputStreamReader(is, StandardCharsets.UTF_8))) {

                content = br.lines().collect(
                      Collectors.joining(System.lineSeparator()));
            }

        } catch (IOException ex) {

            content = String.format("Cannot read webpage %s", ex);
            Logger.getLogger(WebPageReader.class.getName()).log(Level.SEVERE, null, ex);
        }

        return content;
    }

    private boolean validateUrl(String webpage) {

        UrlValidator urlValidator = new UrlValidator();

        return urlValidator.isValid(webpage);
    }
}

WebPageReader validates the URL and reads the contents of the web page. It returns a string containing the HTML code of the page.

<!DOCTYPE html>
<html>
    <head>
        <title>Home page</title>
        <meta charset="UTF-8">
    </head>
    <body>
        <form action="ReadWebPage">

            <label for="page">Enter a web page name:</label>
            <input  type="text" id="page" name="webpage">

            <button type="submit">Submit</button>

        </form>
    </body>
</html>

Finally, this is the home page containing the HTML form. This is taken from my tutorial about this topic.

If you would like to mount a particular host directory (/disk1/prometheus-data in the following example) as a volume in the volumes section of the Docker Compose YAML file, you can do it as below, e.g.:

version: '3'

services:
  prometheus:
    image: prom/prometheus
    volumes:
      - prometheus-data:/prometheus

volumes:
  prometheus-data:
    driver: local
    driver_opts:
      o: bind
      type: none
      device: /disk1/prometheus-data

By the way, in prometheus's Dockerfile, You may find the VOLUME instruction as below, which marks it as holding externally mounted volumes from native host, etc. (Note however: this instruction is not a must though to mount a volume into a container.):

Dockerfile

...
VOLUME ["/prometheus"]
...

Refs:

• https://docs.docker.com/compose/compose-file/#driver
• https://docs.docker.com/compose/compose-file/#driver_opts

For input number in range 0..100

int n1 = 75; // input value
String res; int n=0; 
int[] a ={0,20,35,55,70,85,101};

for(; n1>=a[n]; n++);
switch(6-n+1) {
  case 1: res="A"; break;
  case 2: res="B"; break;
  case 3: res="C"; break;
  case 4: res="D"; break;
  case 5: res="E"; break;
  default:res="F";
}
System.out.println(res);

For Firefox you need to go a little deeper with this:

var imgs = document.getElementsByTagName('img');

    // loop through fetched images
    for (i = 0; i < imgs.length; i++) {
        // and define onmousedown event handler
        imgs[i].onmousedown = disableDragging;
    }

function disableDragging(e) {
        e.preventDefault();
    }

Enjoy.

I ended up doing this:

    public static string ToStringNullSafe(this object obj)
    {
        return obj != null ? obj.ToString() : String.Empty;
    }
    public static bool Compare<T>(T a, T b)
    {
        int count = a.GetType().GetProperties().Count();
        string aa, bb;
        for (int i = 0; i < count; i++)
        {
            aa = a.GetType().GetProperties()[i].GetValue(a, null).ToStringNullSafe();
            bb = b.GetType().GetProperties()[i].GetValue(b, null).ToStringNullSafe();
            if (aa != bb)
            {
                return false;
            }
        }
        return true;
    }

Usage:

    if (Compare<ObjectType>(a, b))

Update

If you want to ignore some properties by name:

    public static string ToStringNullSafe(this object obj)
    {
        return obj != null ? obj.ToString() : String.Empty;
    }
    public static bool Compare<T>(T a, T b, params string[] ignore)
    {
        int count = a.GetType().GetProperties().Count();
        string aa, bb;
        for (int i = 0; i < count; i++)
        {
            aa = a.GetType().GetProperties()[i].GetValue(a, null).ToStringNullSafe();
            bb = b.GetType().GetProperties()[i].GetValue(b, null).ToStringNullSafe();
            if (aa != bb && ignore.Where(x => x == a.GetType().GetProperties()[i].Name).Count() == 0)
            {
                return false;
            }
        }
        return true;
    }

Usage:

    if (MyFunction.Compare<ObjType>(a, b, "Id","AnotherProp"))

<form action="" method="post" enctype="multipart/form-data">
<input type="file" multiple name="img[]"/>
<input type="submit">
</form>
<?php
print_r($_FILES['img']['name']);
?>

create table Table1
(
  id varchar(2),
  name varchar(2),
  PRIMARY KEY (id)
)


Create table Table1_Addr
(
  addid varchar(2),
  Address varchar(2),
  PRIMARY KEY (addid)
)

Create table Table1_sal
(
  salid varchar(2),`enter code here`
  addid varchar(2),
  id varchar(2),
  PRIMARY KEY (salid),
  index(addid),
  index(id),
  FOREIGN KEY (addid) REFERENCES Table1_Addr(addid),
  FOREIGN KEY (id) REFERENCES Table1(id)
)

You can this query:

pip install image 

I had pillow installed, and still, I got the error that you mentioned. But after I executed the above command, the error vanished. And My program worked perfectly.

When an Amazon RDS instance is blocked because the value of max_connect_errors has been exceeded, you cannot use the host that generated the connection errors to issue the "flush hosts" command, as the MySQL Server running on the instance is at that point blocking connections from that host.

You therefore need to issue the "flush hosts" command from another EC2 instance or remote server that has access to that RDS instance.

mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts

If this involved launching a new instance, or creating/modifying security groups to permit external access, it may be quicker to simply login to the RDS user interface and reboot the RDS instance that is blocked.

Here's one more alternative:

var classElements = document.getElementsByClassName("className");

function setClassHeight (classElements, desiredHeightValue) 
    {
        var arrayElements = Object.entries(classElements);
        for(var i = 0; i< arrayElements.length; i++) {
            arrayElements[i][1].style.height = desiredHeightValue;
        }

    }
